Description

  The present invention relates to a rear structure of a vehicle, and more particularly to a power feeding structure to an electronic component provided in an openable glass hatch at the rear of the vehicle.

  The glass hatch functions as a window for visually recognizing the rear of the driver when closed. Therefore, for example, if fine water droplets adhere to the surface of the glass hatch due to different temperatures inside or outside the vehicle during cold weather, the glass hatch may become cloudy and visibility behind the vehicle may be reduced. In order to prevent the occurrence of such problems, conventionally, a glass hatch has a defogger formed by arranging a plurality of heating wires in parallel. Haze is removed.

  Such a defogger is generally provided with a plurality of heating wires arranged in parallel to each other and bus bars connected to these heating wires at both sides in the vehicle width direction of the glass hatch to supply power. It is provided over a wide range in the center of the hatch (for example, see Patent Document 1 below). In this case, the bus bar provided on one side of the glass hatch in the vehicle width direction serves as a positive terminal, and the bus bar provided on the other side serves as a negative terminal.

  Also, this type of glass hatch may be equipped with electronic parts such as a wiper for removing raindrops and a wiper driving motor. For example, when a wiper drive motor is provided on a glass hatch, the wire harness routed from the vehicle body is connected to the wiper drive motor as a motor power supply harness, and a protector that covers the wire harness is fixed to the glass hatch. (See, for example, Patent Document 2 below).

JP 2007-76609 A JP 2000-247193 A

  By the way, the glass hatch functions not only as a rear window of the vehicle but also as an opening / closing door, so that it is necessary to be able to perform the opening / closing operation comfortably and safely while ensuring the visibility behind the vehicle when closed. There is. Therefore, in order to meet these requirements, efforts are being made to reduce the number of parts mounted on the glass hatch. Alternatively, with the exception of some parts such as wipers, as much as possible, efforts are made to attach them to the vehicle body side rather than the glass hatch side. On the other hand, for example, with regard to a glass hatch locking device, there is a demand to provide a latch on the glass hatch side and a striker that engages the latch on the vehicle body side for the purpose of improving the operability of the opening / closing operation. . In this case, the on / off operation of the engagement (locking) operation between the latch and the striker can be performed by using a switch provided in the vehicle interior or a remote control from outside the vehicle compartment, for example, an electromagnetic switch using an electrical signal as an operation switch. This is done by adopting a latch of the formula (so-called E latch). However, when this type of latch is fixed to the glass hatch, as in the case of the wiper motor described in Patent Document 2, a harness for feeding power to the electromagnetic latch and a protector for covering this feeding harness are provided. It is necessary to arrange or fix on the glass hatch. This deteriorates the appearance of the glass hatch, increases the weight of the harness cover, and increases the cost. In particular, glass hatches are counted as one of the characteristics that should be emphasized not only in functionality but also in appearance (beauty). Therefore, increasing the number of fitted items unnecessarily increases the commercial value of vehicles equipped with glass hatches. May result in diminishing the

  The above problems are not limited to electromagnetic latches, but are problems that require power supply and apply to all electronic components mounted on the glass hatch.

  In view of the above circumstances, there is provided a rear structure of a vehicle capable of mounting a predetermined electronic component on a glass hatch at a low cost while reducing the weight and improving the appearance required for this type of glass hatch. This is a technical problem to be solved by the present invention.

The solution to the above problem is achieved by the vehicle rear structure according to the present invention. In other words, the rear structure of this vehicle is such that a defogger and predetermined electronic components are arranged on the interior surface of a glass hatch that is attached to the vehicle body so as to be openable and closable. In the rear structure of the vehicle, the positive terminal and negative terminal connected to the power supply harness routed from the vehicle body side are connected to the parts, respectively, and the periphery of the glass hatch is colored. The electronic component is attached to the lower part of the vehicle interior surface of the glass hatch, and two harnesses that connect the electronic component and the terminal are formed by printing at a predetermined position on the vehicle interior surface together with the heating wire of the defogger. Both the heating wire connected to the power supply harness and the terminal of the electronic component are arranged in the colored coating region on one side of the glass hatch in the vehicle width direction, thereby the negative electrode side terminal of the heating wire and the negative electrode side end of the electronic component. : It is shared Rutotomoni, two harness extends from a lower portion of the vehicle interior surface along the heating wire which forms the periphery of the defogger to the vehicle width direction the one side, and shared by the negative terminal This is characterized by the fact that the positive electrode side terminal of the electronic component is disposed on the outer side in the vehicle width direction .

  Thus, in the present invention, the power supply harness for the electronic component is formed by printing on the interior surface of the glass hatch, so that the harness can be formed linearly on the glass hatch. In addition, this makes it possible to omit the wire harness cover that has been required in the past, which greatly reduces the apparent proportion of the harness for electronic components in the glass hatch and greatly improves the appearance (beautiful appearance) of the glass hatch. Can be increased. Further, by omitting the harness cover, it is possible to reduce the number of components and reduce the number of mounting points on the glass hatch to reduce the weight of the hatch. Further, as described above, by forming both the electronic component harness and the heating wire by printing, the harness and the heating wire can be simultaneously formed on the glass hatch by one printing operation. As a result, the assembling property and productivity can be improved, the work man-hour (assembly man-hour) can be reduced, and the electronic component harness can be formed on the glass hatch at low cost.

  In addition to the above-described configuration, the present invention is such that the heating wire connected to the power supply harness routed from the vehicle body side and the terminal of the electronic component are all disposed on one side of the glass hatch in the vehicle width direction. It is a further feature. In the conventional defogger power feeding structure, the terminals connected to the heating wires of the defogger arranged in parallel to each other along the vehicle width direction are arranged on both sides of the glass hatch in the vehicle width direction. Therefore, when a power supply harness (wire harness) wired from the vehicle body side is connected to this terminal, the power supply harness hangs down on both sides of the glass hatch in the vehicle width direction, which is very unpleasant. There was a problem. On the other hand, in the present invention, as described above, the terminals of the heating wire and the electronic component connected to the power feeding harness from the vehicle body side are concentrated on one side of the glass hatch in the vehicle width direction. By reducing the number of power supply harnesses connected to the cable, it is possible to further improve the appearance, simplify the wiring, and reduce the weight. In addition, by disposing each terminal in this way, the negative electrode side terminal as a ground can be shared by the electronic component and the heating wire. Therefore, this can also simplify the wiring and reduce the weight. In this case, since various components arranged on the glass hatch are biased to one side in the vehicle width direction, there is a risk that the appearance (appearance) of the glass hatch may be reduced. Since the terminal group concentratedly arranged on one side in the width direction is placed on the colored coating region provided on the peripheral edge of the glass hatch, the appearance does not deteriorate.

  As described above, according to the rear structure of the vehicle according to the present invention, while reducing the weight required for the glass hatch attached to the vehicle body so as to be openable and closable and improving the appearance, Parts can be mounted at low cost.

1 is a rear view of a vehicle having a vehicle rear structure according to an embodiment of the present invention. It is the figure which planarly viewed the glass hatch provided in the rear part of the vehicle shown in FIG. 1 from the vehicle interior side.

  Hereinafter, an embodiment of a rear structure of a vehicle according to the present invention will be described with reference to the drawings. In this embodiment, a case where an electromagnetic latch is attached to a glass hatch to supply power will be described as an example. In the following description, the vertical direction is simply referred to as the vertical direction unless otherwise specified.

  FIG. 1 is a view of a vehicle according to the present embodiment as viewed from the rear. As shown in the figure, this vehicle has an opening 3 in a rear surface portion 2 of a vehicle body 1, and an openable / closable glass hatch 4 constituting a rear window of the vehicle body 1 is attached to the opening 3. Has been. The glass hatch 4 has an upper end supported by the rear surface portion 2 of the vehicle body 1 and can be opened and closed by rotating around the support, and at the time of closing the glass hatch lock device provided at the lower end. By this, it is fixed to the vehicle body 1 (rear surface portion 2). Although not shown, a weather strip that is in close contact with the interior surface of the glass hatch 4 may be fitted over the entire periphery of the opening 3.

  The glass hatch lock device includes an electromagnetic latch 5 fixed to the glass hatch 4 side and a striker (not shown) fixed to the rear surface 2 side. The electromagnetic latch 5 and the striker are engaged with each other. By forming the state, the glass hatch 4 can be closed with respect to the rear surface portion 2. Here, a known method using the electromagnetic latch 5 can be adopted for the lock and unlock operation by the glass hatch lock device. For example, by operating a remote controller for locking and unlocking operation outside the passenger compartment, electricity is supplied from the battery to the actuator built in the electromagnetic latch 5, thereby actuating the actuator to operate the electromagnetic latch 5 and the striker. You may make it form or cancel an engagement state. Alternatively, as shown in FIG. 1, a button-type switch 6 that can be operated from outside the vehicle compartment is provided at a predetermined position (here, the lower end portion of the glass hatch 4) of the glass hatch 4, and the remote controller is When the switch 6 is operated from the outside of the passenger compartment while being placed in the passenger compartment or with the engine key inserted into the key cylinder of the instrument panel, electricity may be supplied to the actuator. . In short, in any operation mode, it is sufficient that the engagement state between the electromagnetic latch 5 and the striker is released by power feeding. By releasing the engagement state, the electromagnetic latch 5 fixed to the glass hatch 4 is detached from the striker fixed to the rear surface portion 2 of the vehicle body 1, so that the lower end portion of the glass hatch 4 is fitted to the opening 3. There is a reaction force from the weatherstrip that has been lifted up slightly. Therefore, the glass hatch 4 can be opened with respect to the rear surface portion 2 of the vehicle body 1 by gripping the lifted lower end portion and rotating the glass hatch 4 upward.

  FIG. 2 is a plan view of the glass hatch 4 shown in FIG. 1 from the vehicle interior side. As shown in the figure, a defogger 7 is provided at the central portion of the glass hatch 4 as a fog stop. The defogger 7 has a plurality of heating wires 8 disposed substantially horizontally and parallelly at a predetermined line interval on the interior surface of the glass hatch 4. Bus bars 9 and 10 for electrically connecting the heating wire 8 to terminals 11 and 12 to be described later are attached. In this embodiment, the two bus bars 9 and 10 are one side part (right side in FIG. 1) of the plurality of heating wires 8 and separated from each other in the vertical direction. The upper bus bar 9 is fixed to the interior surface of the glass hatch 4 with the upper bus bar 9 as the positive electrode side and the lower bus bar 10 as the negative electrode side. Half of the plurality of heating wires 8 arranged in parallel with each other are connected to the upper and lower bus bars 9 and 10, respectively, and at the other side in the vehicle width direction (left side in FIG. 1) via the connecting portion 8a. The half of the heating wires 8 are connected to each other.

  Terminals 11 and 12 for connecting to a power supply wire harness (not shown) wired from the vehicle body 1 side are fixed to the bus bars 9 and 10. Here, the terminal 11 fixed to the upper bus bar 9 functions as a positive terminal, and the terminal 12 fixed to the lower bus bar 10 functions as a negative terminal. A voltage is applied so that all of the plurality of heating wires 8 can generate energized heat. In addition, the form of the terminals 11 and 12 is arbitrary. For example, the terminals 11 and 12 themselves may have a predetermined connector shape corresponding to the connector provided at the distal end of the wire harness. May have a shape that can be attached to the terminals 11 and 12.

  The heating wire 8 (including the connecting portion 8a) constituting the defogger 7 is formed by various known printing means. As an example, a paste-like body containing conductive metal powder such as silver is printed in a thin line shape by screen printing at the above-mentioned predetermined position of the glass hatch 4 material before heat treatment, and then the glass hatch 4 material is predetermined. By performing this heat treatment (usually performed for the purpose of strengthening the glass hatch 4), for example, the heating wire 8 is baked into the pattern shown in FIG.

  An electromagnetic latch 5 for locking and unlocking the glass hatch 4 is fixed to an outer region of the defogger 7 (region closer to the peripheral edge of the glass hatch 4) on the interior surface of the glass hatch 4. The electromagnetic latch 5 is connected to positive and negative terminals 12 and 13 connected to a power supply wire harness routed from the vehicle body 1 side via predetermined harnesses 14 and 15 as described above. Here, the positive terminal 13 is disposed in the vicinity of the terminals 11 and 12 for the defogger 7 on the interior surface of the glass hatch 4. The negative terminal 12 is shared with the negative terminal 12 for the defogger 7 for grounding. Therefore, the positive-side terminal 13 is connected to the positive-side terminal 16 disposed in the vicinity of the electromagnetic latch 5 through the corresponding one harness 14, and the negative-side terminal 12 is connected to the corresponding other harness. 15 is connected to a terminal 17 on the negative electrode side disposed in the vicinity of the electromagnetic latch 5. The terminals 16 and 17 disposed in the vicinity of the electromagnetic latch 5 are both connected to the electromagnetic latch 5 via a covered electric wire, whereby the terminals 12 and 13 are connected to the power supply wire harness from the vehicle body 1 side. Predetermined electricity is supplied to the electromagnetic latch 5 via the harnesses 14 and 15 and the terminals 16 and 17, and the engaging operation with the striker provided in the vehicle body 1 or the releasing operation of the engaging state is performed. ing.

  Here, the power supply harnesses 14 and 15 of the electromagnetic latch 5 are both formed by printing, and are preferably formed by using the same material and the same printing means as the heating wire 8 of the defogger 7. This is because both the heating wire 8 and the harnesses 14 and 15 are on the same surface, and both of them can be energized enough to withstand the use of the conductive paste obtained by printing. As described above, when the heating wire 8 and the harnesses 14 and 15 are formed of the same material and a common printing means, the line width (thickness) of the portion printed in the thin line shape is set as the electric wire. It is preferable that the portion used as the heat wire 8 is different from the portion used as the harnesses 14 and 15. For example, the line width of the part used as the harnesses 14 and 15 of the electromagnetic latch 5 can be made larger than the line width of the part used as the heating wire 8.

  At the peripheral edge of the glass hatch 4, there is provided a colored paint region, here a black paint region 18 also called blackout (see FIG. 2). The terminals 11 and 12 of the defogger 7 (heating wire 8) connected to the power supply wire harness (not shown) routed from the vehicle body 1 side, and the terminals 12 of the electromagnetic latch 5 connected to the same wire harness as described above. , 13 are disposed on a region corresponding to one side portion of the glass hatch 4 in the vehicle width direction in the black coating region 18. Further, in this embodiment, not only the terminals 11, 12, 13 but also both sides of the heating wire 8 constituting the defogger 7 in the vehicle width direction (including the connecting portion 8 a), the bus bars 9, 10, and the electromagnetic latch 5 And terminals 16, 17 fixed in the vicinity of the electromagnetic latch 5, and harnesses 14, 15 for connecting the terminals 16, 17 in the vicinity of the electromagnetic latch 5 and the terminals 12, 13 on the power supply wire harness side, However, all are arrange | positioned on the black coating area | region 18 (refer FIG. 2).

  As described above, in the rear structure of the vehicle, since the harnesses 14 and 15 for supplying power to the electromagnetic latch 5 are formed on the interior surface of the glass hatch 4 by printing, the harnesses 14 and 15 are formed on the glass hatch. 4 can be formed linearly. As a result, the apparent ratio of the harnesses 14 and 15 to the glass hatch 4 can be made very small, and the appearance (beauty appearance) of the glass hatch 4 can be remarkably enhanced. Moreover, since the harness cover conventionally required when a wire harness is used can be omitted, the number of parts can be reduced, the cost can be reduced, and the glass hatch 4 can be reduced in weight. Further, as described above, the harnesses 14 and 15 of the electromagnetic latch 5 and the heating wire 8 of the defogger 7 are both formed by printing, so that the harnesses 14 and 15 and the heating wire 8 can be simultaneously formed by a single printing operation. It can be formed on the hatch 4. As a result, the assemblability and productivity can be improved, the work man-hour (assembly man-hour) can be reduced, and the harnesses 14 and 15 can be formed on the glass hatch 4 at low cost.

  In particular, in the case of the electromagnetic latch 5, the current to be supplied from the battery is sufficient for the electric signal level for switching on and off the operation of the actuator incorporated in the electromagnetic latch 5, and switching. Since only a short energization time is required only during operation, there is no problem of durability when the printed harnesses 14 and 15 are energized.

  In this rear structure, the heating wire 8 connected to the power supply wire harness routed from the vehicle body 1 side and the terminals 11, 12, 13 of the electromagnetic latch 5 are all on one side in the vehicle width direction of the glass hatch 4. The power supply wire harness routed from the vehicle body 1 side and the terminal are connected to both sides of the defogger 7 (heating wire 8) in the vehicle width direction as in the past. Compared with the case where the number of wire harnesses for feeding is reduced to one, it is possible to further improve the appearance, simplify the wiring, and reduce the weight. Further, the terminals 11, 12, and 13 are collectively arranged on one side in the vehicle width direction, so that the negative electrode side terminal 12 as a ground can be shared by the electromagnetic latch 5 and the heating wire 8. . Therefore, this can also simplify the wiring and reduce the weight. Moreover, in this rear structure, since the terminals 11, 12, and 13 collectively arranged on one side in the vehicle width direction of the glass hatch 4 are placed on the black coating region 18 provided on the peripheral edge of the glass hatch, You don't have to look bad. Further, the electromagnetic latch 5 is disposed outside the glass hatch 4 (side closer to the peripheral edge) than the defogger 7, so that the electromagnetic latch 5, and the electromagnetic latch 5 and one side portion in the vehicle width direction are arranged. All the connection structure portions (the harnesses 14 and 15 and the terminals 16 and 17 on the electromagnetic latch 5 side) between the terminals 12 and 13 that are collectively arranged on the black coating region 18 can be arranged. Therefore, it is possible to hide all the mounting parts other than the heating wire 8 of the defogger 7 from the outside of the vehicle compartment, thereby ensuring the appearance of the glass hatch 4.

  In the above embodiment, the electromagnetic latch 5 is illustrated as an electronic component on which a power supply harness is to be printed. However, the present invention can also be applied to other electronic components. For example, although not shown in the drawings, the present invention can be applied to various electronic parts such as lighting parts such as HMSL (High Mount Stop Lamp) and driving parts such as a wiper (wiper motor). In addition, if the electronic component does not require regular electric supply such as the electromagnetic latch 5 or HMSL and the supply current amount is relatively small, the material and wire of the printed harness (power supply wire) This is preferable because the room for selection of width, printing method, and the like is widened.

  In the above description, the case where the glass hatch 4 is attached to the opening 3 of the rear surface portion 2 provided integrally with the vehicle body 1 is illustrated, but a back door (not shown) is provided at the rear portion of the vehicle body 1. It is also possible to apply the present invention to a vehicle having a glass hatch 4 in an opening provided in the back door.

  Of course, other specific forms can be adopted for matters other than the above as long as the technical significance of the present invention is not lost.
