Description

A PATCH FOR USE IN REPLACEMENT OF A RIVET AND A METHOD FOR REPLACING
A RIVET
TECHNICAL FIELD
The present disclosure relates to a patch for use in replacement of a rivet and a method for replacing a rivet. In particular, but not exclusively, it relates to a patch for use in replacement of a rivet and a method for replacing a rivet in a vehicle.
Aspects of the invention relate to a patch, a method, a vehicle part and a vehicle.
BACKGROUND
Rivets, such as self-piercing rivets (SPRs) are used to join layers of materials together, for example, in an automotive application to create a vehicle body structure. In particular, selfpiercing rivets are particularly useful in manufacture of predominantly aluminium or aluminium alloy vehicle body structures, where the SPR is arranged to create its own aperture in the material of the body panels it is being used to secure together, thus negating the need to pre-drill holes for each rivet.
Under certain circumstances a rivet, such as an SPR may need to be removed, for example to allow replacement of a damaged panel of material. In conventional methods a fitted rivet, such as an SPR, is drilled out leaving a hole at the original location of the fitted SPR. Accordingly, if a new or replacement SPR is to be fitted, for example to attach a replacement panel, the original location for the SPR cannot be used and a new location for the replacement rivet must be found for use.
In some circumstances, such as if multiple repairs are required, there may be no suitable locations for a new rivet, such as an SPR, to be fitted. This may render the object unrepairable and therefore out of use.
In addition, during vehicle production for example, the production process may change the properties of materials joined using a rivet, such as an SPR, such as adhesives in and between a stack of materials. Accordingly, if a new rivet, such as an SPR, is fitted an unsatisfactory joint may be achieved due to the change in the material properties subsequent to the original fitting of the rivet.
It is an aim of the present invention to improve upon known techniques for the replacement of a rivet in the repair of a riveted structure.

Examples and aspects of the present invention relate to replacement of a rivet such as a self-piercing rivet.
The following description and the examples shown in the Figures, are directed to the use of self-piercing rivets. However, the present disclosure is not intended to be limited to selfpiercing rivets and the patch and associated methods described below for using the patch may be used for a variety of different types of rivets such as a pop-rivet (blind-rivet); a selfpiercing rivet (SPR); a semi-tubular rivet; or a flush rivet. It will be appreciated that other types of rivet may be useful. Whilst the following description refers to a self-piercing rivet it is to be understood that the self-piercing rivet (SPR) is used by way of example only and that aspects of the present invention are not limited to the exclusive use with SPRs.
In examples, a patch is located in a hole created by removal of a self-piercing rivet to allow a new self-piercing rivet to be fitted at the original location of the removed self-piercing rivet. A technical effect of at least some examples of the disclosure is that the use of a patch in replacement of a rivet, such as a self-piercing rivet, allows a new self-piercing rivet to be fitted at the original location meaning that, for example, unlimited repairs to a vehicle body can be made without exhausting locations for self-piercing rivet joints.
Furthermore, the use of patch in replacement of a self-piercing rivet also allows for control of the materials used in the new self-piercing rivet to provide for good quality consistent selfpiercing rivet joints to be formed.
Additionally or alternatively the use of a patch in replacement of a self-piercing rivet provides that the button created by the new self-piercing rivet joint will be no thicker than the original self-piercing rivet joint. As a result, there will be no issues relating to, for example, fitting surrounding panels or seals over a new joint that can only tolerate certain overall thicknesses.
The use of a patch in replacement of rivets, such as self-piercing rivets, facilitates repair, permits component replacement and thus extends the service life of a riveted vehicle body in use.
Figs 1, 2, 3A to 3C, 4 and 7 illustrate a patch 10 for use in replacement of a self-piercing rivet 12, comprising; a protrusion 14 for fitting into a hole 16 created by removal of a selfpiercing rivet 12; and a flange area 18 adjacent to the protrusion 14.
Figs 5 and 6 illustrate a method 500, 600 for replacing a self-piercing rivet 12, comprising; removing a fitted self-piercing rivet 12; locating a patch 10 as described herein in a hole 16 created by removal of the self-piercing rivet 12; and applying a new self-piercing rivet 30 at the location 48 of the patch 10.
Fig 1 schematically illustrates an example of a patch 10 for use in replacement of a selfpiercing rivet 12. It is noted that some of the features referred to in relation to Figs 1 to 6 are illustrated in the example of Figs 7 and 8.
The patch 10 of Fig 1 may be comprised in a vehicle part 44 which may in turn be comprised in a vehicle 46. See, for example, the examples of Figs 2 and 8.
The patch 10 illustrated in the example of Fig 1 comprises a protrusion 14 and a flange area 18.
The protrusion 14 is for fitting into a hole 16 created by removal of an SPR. In some examples, the protrusion 14 is for fitting into a hole 16 that has been modified following creation of the hole 16 by removal of the SPR 12. In such examples, the modified hole 16 may still be considered to be the hole 16 created by removal of an SPR 12.
For example, the protrusion 14 may be for fitting into a hole 16 that has been modified by chamfering of the hole 16.
In examples, the protrusion 14 may be of any suitable size and/or shape. For example, the size and/or shape of the protrusion 14 may be selected in dependence upon the hole 16 created by removal of the SPR 12.
In some, but not necessarily all, examples the protrusion 14 may be circular in shape to match the hole 16 created by drilling out of a SPR 12.
Additionally or alternatively, the protrusion 14 may be tapered to match a modified hole 16 that has been chamfered (see, for example, the example of Fig 3C and Fig 7). The protrusion 14 may be tapered by any suitable amount.
The protrusion 14 may have any suitable height. The height of the protrusion 14 may be selected in dependence upon the usage of the patch 10. See, for example, Fig 3C.
In some examples, the protrusion 14 is for providing an interference fit 20 with the hole 16. For example, the size and/or shape and/or height of the protrusion may be selected to provide an interference fit with a hole 16 created by removal of an SPR 12.
In examples the patch 10 may comprise a plurality of protrusions 14.
In some examples the patch may comprise one or more apertures 19 (see Fig 3A) to allow insertion of a replacement rivet or rivets, such as a pop-rivet (blind-rivet), a semi-tubular rivet, or a flush rivet through the aperture(s).
In examples, such as the one illustrated in Fig 3A, the aperture 19 may be located on the protrusion 14.
The flange area 18 may be adjacent the protrusion 14. In some examples, the flange area 18 surrounds at least one edge 22 of the protrusion 14. See, for example, Figs 3A and 3B.
That is, in some examples, the flange area 18 may be located in every direction around an edge 22 of the protrusion 14.
The flange area 18 may have any suitable size and/or shape. In examples, the size and/or shape of the flange area 18 may be selected in dependence upon the intended use of the patch 10. For example, the size and/or shape of the flange area 18 may be selected to match the intended use location of the patch 10.
In examples, the flange area 18 comprises a first portion 32 extending from the protrusion 14 in a first direction 34 and a second portion 36 extending from the protrusion 14 in a second direction 38. The second direction 38 may be opposite to the first direction 34. See, for example, Figs 3A to 3C and Fig.4.
In examples, the first portion 32 and second portion 36 may be of the same shape and/or size. In other examples, the first portion 32 and second portion 36 may be of different shapes and/or sizes.
The flange area 18 may be for abutting a surface of a material stack 28 through which the replacement SPR is to be fitted (see, for example, Fig 7).
Additionally or alternatively the flange area 18 may provide at least one surface 24 for receiving adhesive 26 to adhere the patch 10 to a material stack 28 that is to receive a replacement SPR 30. See, for example, Fig 7.
In some examples, the flange area 18 forms a plane to abut against the surface of a material stack 28 to support the protrusion 14 when it is located in a hole 16 created by removal of an SPR 12 and/or to provide at least one surface 24 for receiving adhesive.
For example, the surface of the flange area 18 that is to abut the material stack 28 may be provided with an adhesive 26 to adhere the patch 10 to the material stack 28. The use of the adhesive 26 may provide for a stronger SPR joint.
In examples any suitable adhesive 26 may be used. For example epoxies and/or single or two component adhesives and/or polyurethane structural adhesives and so on.
The patch 10 is considered for use in replacement of an SPR 12 as it allows for a new SPR 30 to be fitted in the hole 16 created by removal of an SPR 12. That is, the patch 10 allows for fitting of a new SPR 30 but does not itself replace an SPR 12.
The patch 10 may have any suitable size and/or shape. In examples, the size and/or shape of the patch 10 may be selected in dependence on the intended use of the patch 10. For example, the size and/or shape of the patch 10 may be selected in dependence upon the intended location of use of the patch 10 on a vehicle part 44 and/or on a vehicle 46.
The patch 10 may be made of/comprise any suitable material or materials.
The material of the patch 10 may be selected to have properties that ensure a satisfying strength and quality of SPR joint. For example the material or materials of the patch 10 may be selected to ensure a good SPR joint can be created using the patch 10.
In examples the material or materials of the patch 10 have a ductility percentage of approximately 20%. In some examples, an aluminium alloy that does not comprise silicon as an alloying element may be used.
Some examples of suitable materials are aluminium 5000 series, non-heat treatable aluminium, for example NG5754, and so on.
The patch 10 of Fig 1 may be made using any suitable method. For example, the patch 10 may be made using a forming process such as stamping or pressing and so on.
The patch 10 may comprise any number of additional elements not illustrated in the example of Fig 1.
For example, the patch 10 may comprise a recess 40. The recess 40 may correspond to the protrusion 14. For example, the recess 40 may be the reverse feature of the protrusion 14 on the patch 10. See, for example, Figs 3A to 3C. In some example, the recess 40 may not correspond to the protrusion 14.
In some examples, the recess 40 may include an aperture for receiving a non self-piercing type rivet, such as a pop-rivet (blind-rivet), a semi-tubular rivet; or a flush rivet as may be appropriate for a given riveted joint.
In examples, a recess 40 of the patch 10 is for providing a location aid 42 for application of a new SPR 30. For example, the recess 40 may provide an aid in locating a die 54 for fitting of a new SPR 30. See, for example, Fig 7.
Throughout the description like numerals will be used to indicate like features.
Fig 2 schematically illustrates an example of a vehicle part 44. In the example of Fig 2 the vehicle part 44 is comprised in a vehicle 46 and comprises a patch 10 illustrated in Fig 1.
In the example of Fig 2, the patch 10 is comprised in the vehicle part 44 as part of replacement of one or more SPRs 12 to replace one or more panels of the vehicle part 44 in the vehicle 46. For example, the patch 10 may be comprised in a vehicle part 44 in the vehicle 46 as part of a repair of the vehicle part 44.
In examples, the vehicle part 44 may be any suitable vehicle part. For example, the vehicle part 44 may be an external part of a vehicle structure such as a vehicle body side, a rear quarter panel, an outer pillar panel and so on.
In some examples, the vehicle part 44 may comprise a plurality of patches 10.
The vehicle 46 may be any suitable vehicle 46 such as a car, van or truck and so on. In examples, the vehicle 46 may comprise a plurality of vehicle parts 44 comprising at least one patch 10.
An example of a vehicle 46 comprising a patch 10 is illustrated in Fig 8.
Figs 3A to 3C illustrate an example of a patch 10 for use in replacement of a self-piercing rivet 12. The patch 10 illustrated in the examples of Figs 3A to 3C is an example of a patch 10 illustrated in Figs 1 and/or 2.
In Fig 3A a top-down or plan view of the patch 10 is illustrated. In the example of Fig 3A, the protrusion 14 is circular and is pointing out of the page.
In Fig 3A, the protrusion 14 is tapered. This is illustrated in the figure by the diameter d1 of the circle at the base of the protrusion 14 being larger than the diameter d2 of the circle at the tip of the protrusion 14. The tapering of the protrusion 14 is illustrated more clearly in the example of Fig 3C.
Accordingly, in the example of Fig 3A the protrusion 14 is for fitting into a hole 16 that has been modified by chamfering of the hole 16. See, for example, Fig 7.
In examples, the diameters d1 and d2 may have any suitable size. For example, the diameter d1 may be dependent upon the diameter of the SPR 30 that is to be applied. For example, the diameter d1 may be chosen during manufacturing of the patch 10 in dependence upon the diameter of the SPR 30 that the patch 10 will be used with.
In some examples the diameter d1 is at least two times the diameter of the shaft of the SPR 30 that is to be applied to accommodate the SPR 30 that is to be applied. A typical value for d1 is approximately 10mm.
In examples, the difference between the d1 diameter and d2 diameter may be any suitable value. That is, in examples, the amount of tapering or chamfering of the protrusion 14 may be any suitable amount. For example, the amount of tapering of the protrusion 14 may match the amount of chamfering of the hole 16 into which the protrusion 14 is to be placed and/or may be selected to provide an interference fit 20.
In examples the patch 10 may comprise one or more apertures 19 to allow insertion of a replacement rivet. This is illustrated in Fig 3A by the dotted circular line on the protrusion 14.
In examples, the aperture 19 of the patch 10 may provide the aperture 19 into which a replacement pop-rivet (blind-rivet), a semi-tubular rivet, or a flush rivet may be fitted.
The aperture 19 may have any suitable size and shape to facilitate fitting of a replacement rivet such as a pop-rivet (blind-rivet), a semi-tubular rivet, or a flush rivet for example.
In the illustrated example the aperture 19 is located in the protrusion 14. However, in other examples the aperture 19 may be located at any suitable location on the patch 10.
In some examples the patch 10 may comprise a plurality of apertures 19 that may be of the same or different shapes and/or sizes to allow fitting of multiple replacement rivets.
In Fig 3A the flange area 18 surrounds an edge 22 of the protrusion 14. The edge 22 of the protrusion 14 is at the base of the protrusion 14.
In Fig 3A, the flange area 18 comprises a first portion 32 extending from the protrusion 14 in a first direction 34 and a second portion 36 extending from the protrusion 14 in a second direction 38. The second direction 38 is opposite to the first direction 34.
In the example of Fig 3A, the flange area 18 forms a plane for abutting against a material stack 28 that is to receive a new SPR 30. See, for example, Fig 7.
The flange area 18, of the patch 10 in Fig 3A comprises a surface 24 for receiving adhesive 26 to adhere the patch 10 to a material stack 28 that is to receive a replacement SPR 30. In the example of Fig 3A, the adhesive 26 is indicated by a dotted box. However, in examples, the adhesive 26 may cover some or all of the flange area 18.
In some examples, the flange area 18 may comprise a plurality of surfaces for receiving an adhesive 26. In examples, the adhesive may be pre-applied to at least a portion of the flange area 18 which, depending on the type of adhesive used, may be covered by a removable protective film to protect the adhesive from contamination or exposure to air during storage or transport prior to use. In examples, the protective film is removed by a user before the patch is fitted in place and the replacement rivet 30 applied.
In Fig 3A, the flange area 18 has a width W and a length L. In examples, the patch 10 may be considered to have a width W and a length L.
The flange area 18/patch 10 may have any suitable width W and/or length L. In examples the width W of the flange area 18/patch 10 may be dependent upon the size of the diameter d1. For example the width W may be chosen during manufacturing of the patch 10 in dependence upon the diameter d1. In examples the width W may be equal to or greater than diameter d1 + 10mm.
In some examples the length L of the flange area 18/patch 10 may be dependent upon the size of the diameter d1. For example the length L may be chosen during manufacturing of the patch 10 in dependence upon the diameter d1. In examples the length L may be equal to or greater than d1 + 10mm.
In the example of Fig 3A, the patch 10 comprises a recess 40. The recess 40 corresponds to the protrusion 14 and is therefore on the underside of the patch 10 in the example of Fig 3A and not visible in the figure.
Fig 3B illustrates an example of a patch 10 for use in replacement of a self-piercing rivet 12. The example of Fig 3B illustrates a perspective view of the patch 10 illustrated in Fig 3A.
In Fig 3B, the protrusion 14 is directed into the page. Accordingly, the recess 40 corresponding to the protrusion 14 illustrated in Fig 3A can be seen in the example of Fig 3B.
Fig 3C illustrates an example of a patch 10 for use in replacement of a self-piercing rivet 12. The example of Fig 3C illustrates a side view of the patch 10 illustrated in the examples of Figs 3A and 3B.
In the example of Fig 3C, the protrusion 14 can be seen extending upwards from the flange area 18. The tapering of the protrusion 14 is visible in the example of Fig 3C.
In the example of Fig 3C, the protrusion 14 has a height h and the flange area 18 has a thickness t.
In examples, the protrusion 14 may have any suitable height h and/or the flange area 18 may have any suitable thickness t.
For example, the height h of the protrusion 14 may be greater than or equal to 1mm and less than or equal to 3mm. That is, in examples the height h of the protrusion 14 may be in the range 1mm < h < 3mm. In examples the thickness t of the flange area 18 may be chosen in dependence upon the thickness of the vehicle part 44 that the patch 10 will be used with. In examples the thickness t may be less than or equal to 2.5mm.
Fig 4 illustrates an example of a patch 10 for use in replacement of a self-piercing rivet 12. In the example of Fig 4, the patch 10 is the patch illustrated in the examples of Figs 3A to 3C.
In the example of Fig 4, the patch 10 is comprised in a vehicle part 44 and is located in a hole 16 created by removal of a self-piercing rivet 12.
The recess 40 of the patch 10 is visible in Fig 4 and provides a location aid 42 for application of a new self-piercing rivet 30. In the example of Fig 4, the new self-piercing rivet 30 has not yet been applied.
It can be seen from the example of Fig 4 that the patch 10 provides for application of a new SPR 30 at the location 48 of the patch 10 at the recess 40. For example, the recess 40 may provide a location aid for locating a die 54 for use in fitting a new SPR 30. See, for example, Fig.7.
Fig.5 illustrates an example of a method 500. For example, the method 500 may be for replacing a self-piercing rivet 12.
At block 502 a fitted self-piercing rivet 12 is removed.
Any suitable method for removing a fitted self-piercing rivet 12 may be used. For example, removing the self-piercing rivet 12 may comprise drilling out the fitted self-piercing rivet 12.
In examples, removing the self-piercing rivet 12 creates a hole 16 through the material that had previously been the site of the riveted joint.
At block 504 a patch 10 for use in replacement of a self-piercing rivet 12 is located in the hole 16 created by removal of the self-piercing rivet 12.
In examples, the patch 10 may be as described in relation to Figs 1 and/or 2.
The patch 10 may be located in the hole 16 by inserting the protrusion 14 of the patch 10 into the hole 16. See, for example, Figs 4 and 7.
In examples, the protrusion 14 of the patch 10 may provide an interference fit 20 with the hole 16 to maintain the patch 10 in position in the hole 16.
At block 506 a new, that is to say, a replacement rivet 30 such as a self-piercing rivet 30 is applied at the location of the patch 10. Any suitable method for applying the new selfpiercing rivet 30 at the location of the patch 10 may be used.
For example, a die 54 may be positioned in the recess 40 of the patch 10 and a self-piercing rivet driven into the material of the protrusion 14. See, for example, Fig 7.
As the new SPR 30 is driven into the material of the protrusion 14 the displaced material of the protrusion 14 may be forced back into the recess 40. This provides the advantage that the button created by application of the new SPR 30 will not be larger than the original button of the original SPR 12.
In examples, the application of the new self-piercing rivet 30 may hold a repaired or replacement panel on a vehicle part 44.
Fig 6 illustrates an example of another method 600. For example, the method 600 may be for replacing a self-piercing rivet 12.
At block 602 a fitted self-piercing rivet 12 is removed. Block 602 corresponds to block 502 of Fig 5 and may be as described in relation to block 502 of Fig 5.
At block 604 at least one panel of material is removed from a material stack 28 from which the fitted self-piercing rivet 12 was removed. For example, the removed panel 50 may be damaged panel of a vehicle part 44 of a vehicle 46.
At block 606 the hole 16 created by removal of the self-piercing rivet 12 is modified. Any suitable method for modifying the hole 16 may be used. For example, the hole 16 may be chamfered using a countersunk drill or a machine driven hole punch to create a hole having the required shape.
At block 608 adhesive 26 is applied to at least a portion of at least one surface of the flange area 18 of the patch 10. Any suitable adhesive may be used. For example, any suitable adhesive for adhering the patch 10 to the material stack 28 may be used.
In examples, the adhesive 26 may comprise single or two component adhesives and/or polyurethane structural adhesives and so on. Other adhesive materials and compounds are useful.
At block 610 the patch 10 is located in the modified hole 16. This corresponds to block 504 of Fig 5 and may be as described in relation to block 504 of Fig 5.
At block 612 a new panel of material 52 is located on the material stack 28 to be fixed to the material stack 28 by application of the new SPR 30 at the location 48 of the patch 10. Any suitable method for locating the new panel of material 52 on the material stack 28 may be used.
In examples a panel of a vehicle 46 may be located on the material stack 28 to replace a damaged panel that has been removed.
At block 614 a new self-piercing rivet is applied at the location 48 of the patch 10. This corresponds to block 506 of Fig 5 and may be as described in relation to block 506 of Fig 5.
In examples, methods 500 and 600 may be considered methods for repairing one or more items such as one or more vehicles.
Fig 7 illustrates an example of a method for replacing a self-piercing rivet 12. Fig 7 is split into 7 parts labeled A to G respectively.
Part A of Fig 7 illustrates a fitted SPR 12 in a material stack 28 that comprises a panel of material 50 that is damaged and is to be removed.
