Detailed Description

In order to make the above objects, features and advantages of the present invention more comprehensible, embodiments of the present invention are described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, as those skilled in the art will be able to make similar modifications without departing from the spirit and scope of the present invention.

Referring to fig. 1, fig. 1 shows an explosion structure diagram of a protective shell according to an embodiment of the present invention, which provides a protective shell including a first layer 100, a second layer 300, and an intermediate layer 200. The second layer 300 is nested outside the first layer 100 and the intermediate layer 200 is disposed intermediate the first layer 100 and the second layer 300. The first layer 100 is provided with a mounting groove 110 for mounting an article. The article may be, for example, an electronic device such as a mobile phone and a tablet computer. The mounting groove 110 has an opening, and an electronic device such as a mobile phone or a tablet computer can be mounted in the mounting groove 110 through the opening, and a display screen of the electronic device such as the mobile phone or the tablet computer is exposed from the opening of the mounting groove 110. That is, the second layer 300 is disposed at a side of the first layer 100 away from the mounting groove 110. As shown in fig. 1, the first layer 100 has a substantially rectangular parallelepiped structure, and in the view angle shown in fig. 1, the opening of the mounting groove 110 of the first layer 100 faces upward, and the mounting groove 110 has a substantially rectangular parallelepiped shape. The side of the first layer 100 away from the mounting groove 110 may be the outer side portion of the first layer 100 shown in fig. 1, the bottom portion of the first layer 100 shown in fig. 1, or a position where the first layer 100 shown in fig. 1 meets the bottom portion at the outer side portion.

Specifically, in the embodiment shown in fig. 1, the intermediate layer 200 is disposed at the outer side portion of the first layer 100. The case where the intermediate layer 200 is disposed at the bottom of the first layer 100 will be described in other embodiments. The case where the intermediate layer 200 is provided at a position where the first layer 100 meets the bottom portion at the outer side portion will be described in other embodiments.

Specifically, the first layer 100 is a soft layer, and the intermediate layer 200 is a hard layer. The hard layer can be made of metal material, and can also be made of PC plastic. The second layer 300 is used to fix the intermediate layer 200 to the first layer 100. Since the first layer 100 is provided with the mounting groove 110, the article can be directly mounted in the mounting groove 110. The soft first layer 100 may avoid scratching the exterior of the article.

Meanwhile, the soft first layer 100 has a buffering function, and after the protective shell provided with the articles falls, the soft first layer 100 can play a role in buffering.

Since the first layer 100 is a soft layer, if the protective shell falls and the first layer 100 directly contacts with the ground, the first layer 100 will generate a large elastic deformation, and when the impact force is large, the degree of elastic deformation of the first layer 100 is also large. Specifically, when the first layer 100 of the protective shell contacts the ground, the first layer 100 is pressed by the impact force, and the portion of the first layer 100 contacting the ground is elastically compressed and becomes thin. When the impact force is large, the contact part of the first layer 100 and the ground becomes very thin, so that the ground applies the impact force to the article in the mounting groove 110, and the article is easily broken. By providing a hard intermediate layer 200 between the first layer 100 and the second layer 300. Even after the protective case falls to the ground, the first layer 100 is prevented from being largely elastically deformed due to the supporting function of the intermediate layer 200. When the protective shell is grounded and the middle layer 200 plays a supporting role, the middle layer 200 is subjected to a large impact force to generate vibration. The first layer 100 is in direct contact with the middle layer 200 to absorb shock, so that the first layer 100 isolates the shock of the middle layer 200 from being transmitted to the article in the mounting groove 110 to protect the article.

The protective case in fig. 1 is a rectangular parallelepiped, and fig. 2 is a sectional view of the protective case shown in fig. 1 in the width direction. In the embodiment shown in fig. 1 and 2, the first layer 100 has a first sidewall 120 and a first back wall 130 connecting the first sidewall 120. The intermediate layer 200 is ring-shaped, and both the intermediate layer 200 and the second layer 300 are disposed on the first sidewall 120. Statistics show that when the protective shell falls, the probability that the first side wall 120 collides with the ground is high, and the first side wall 120 is a weak position, so that the first side wall 120 needs special protection. In order to reduce the weight of the protective case and make the protective case thinner, both the intermediate layer 200 and the second layer 300 may be disposed on the first sidewall 120.

Further, as shown in fig. 1, the first sidewall 120 is provided with a first fixing groove 140, the intermediate layer 200 and the first fixing groove 140 are both ring-shaped, and the intermediate layer 200 is mounted in the first fixing groove 140. That is, the first fixing groove 140 may play a role of fixing the intermediate layer 200. If the fixing groove 140 is not formed, but the intermediate layer 200 is directly adhered to the surface of the first layer 100 by glue, the intermediate layer 200 is easily delaminated from the first layer 100 in actual use. In addition, if the first fixing groove 140 is not provided, but the intermediate layer is directly injection-molded on the surface of the first layer 100, the intermediate layer 200 is easily separated from the first layer 100 in actual use. It should be noted that, although the first fixing groove 140 for fixing the intermediate layer 200 is provided on the first sidewall 120 as a preferred embodiment, it does not constitute an indication that the first fixing groove 140 for fixing the intermediate layer 200 can be provided only on the intermediate layer 200. For example, the intermediate layer 200 may be adhered to the first layer 100 by glue, or the intermediate layer 200 may be adhered to the first layer 100 by injection molding. Further, the width of the first fixing groove 140 is substantially the same as the width of the intermediate layer 200, so that the side wall of the intermediate layer 200 can be attached to the inner wall of the first fixing groove 140 when the intermediate layer 200 is mounted in the first fixing groove 140. Further, the second layer 300 is also disposed in the first fixing groove 140, and the sum of the thicknesses of the second layer 300 and the intermediate layer 200 is substantially the same as the depth of the first fixing groove 140.

Wherein the second layer 300 may be a soft layer. The second layer 300 may also be a hard layer. It should be noted that the soft layer and the hard layer in the above embodiments are relatively, that is, the soft layer has a lower hardness than the hard layer. For example, the soft layer may be rubber, plastic, etc., and the hard layer may be metal, ceramic, etc. Of course, the soft layer and the hard layer may be the same in material, for example, the soft layer may be made of soft plastic, and the hard layer may be made of hard plastic.

In the embodiment shown in fig. 1, the first layer 100 is made of a TPU (Thermoplastic polyurethane elastomer rubber) material, the middle layer 200 is made of a metal material, and the second layer 300 is made of a TPU material. When the protective case with the article mounted thereon is dropped, the second layer 300 is first in contact with the ground if the side walls of the protective case are in contact with the ground. Since the second layer 300 is made of TPU, that is, the second layer 300 is a soft layer, the portion of the second layer 300 contacting with the ground is elastically compressed to be thinner, and the process of elastic compression of the second layer 300 is a process of buffering the impact force. When the impact force is large, the portion of the second layer 300 contacting the ground becomes so thin that the ground applies the impact force to the middle layer 200. Since the intermediate layer 200 is made of a metal material, the intermediate layer 200 is a hard layer. The middle layer 200 can prevent the protective shell from further elastic deformation, but the middle layer 200 can also generate vibration under the action of impact force. Since the intermediate layer 200 functions to protect the first layer 100 to reduce elastic deformation of the first layer 100, the first layer 100 mainly functions to absorb shock of the intermediate layer 200. In summary, the first layer 100, the second layer 300 and the middle layer 200 cooperate with each other to protect the articles in the mounting groove 110. That is, the second layer 300 absorbs most of the impact force by elastic deformation, the intermediate layer 200 plays a role of supporting to prevent the first layer 100 from being largely deformed, and the first layer 100 mainly plays a role of absorbing the shock of the intermediate layer 200.

In one embodiment, the softer and harder layers may also be differentiated by tactile feel. For example, the soft layer is made of an elastic and soft material, and the soft layer is elastically deformed when pressed by a small amount of force. Whereas the hard layer is substantially made of a harder material. The hard layer may be a hard plastic or metal, for example. For example, in fig. 1, the intermediate layer 200 is metal and the second layer 300 is rigid plastic.

As shown in fig. 3, fig. 3 is a schematic diagram of an explosive structure of a protective shell according to an embodiment of the present invention. As shown in fig. 3, the first layer 100 has a first sidewall 120 and a first back wall 130 connecting the first sidewall 120. The second layer 300 has a second sidewall 310 and a second back wall 320 connecting the second sidewall 310. The second sidewall 310 is disposed on the first sidewall 120. The second back wall 320 is disposed on the first back wall 130. The second sidewall 310 is disposed on the first sidewall 120, and the second sidewall 310 may be in direct contact with the first sidewall 120, or the second sidewall 310 may be in indirect contact with the first sidewall 120; the second back wall 320 is disposed on the first back wall 130, and the second back wall 320 may be in direct contact with the first back wall 130, or the second back wall 320 may be in indirect contact with the first back wall 130. Similarly, when a feature is provided on another feature in the present application, it is intended that the feature may be in direct contact with the other feature or in indirect contact with the other feature. The indirect contact is particularly characterized in that other technical features exist between one technical feature and another technical feature.

As shown in fig. 3, the structure of the first layer 100 is substantially the same as that of the second layer 300. For example, the first layer 100 is substantially rectangular parallelepiped, and the second layer 300 is also substantially rectangular parallelepiped. The first layer 100 is provided with a mounting groove 110 for mounting an article, and the second layer 300 is provided with a groove structure for mounting the first layer 100. The dimensions of the second layer 300 may be slightly larger than the dimensions of the corresponding locations of the first layer 100 to enable the first layer 100 to fit within the channel structure of the second layer 300. That is, the second layer 300 may wrap around the first layer 100. Therefore, when the protective shell is dropped, the opening of the first layer 100 except the mounting groove 110 is exposed to the outside, and other parts of the first layer 100 are wrapped by the second layer 300, so that the second layer 300 can play a role of protecting the first layer 100 in multiple directions.

In one embodiment, as shown in fig. 3, the intermediate layer 200 includes a corner portion 210 and a plate portion 220 connecting the corner portions 210. The corner portion 210 is disposed on the first sidewall 120 of the first layer 100, and the plate portion 220 is disposed on the first back wall 130 of the first layer 100. Specifically, the first layer 100 may be a flat rectangular parallelepiped as a whole, and twelve edges of the rectangular parallelepiped form eight corners in total. The middle layer 200 has four corners 210, and each corner 210 wraps two corners of the first layer 100 disposed in the thickness direction. Thus, when the protective case is dropped, all eight corners are protected by the corner portions 210 of the intermediate layer 200. Further, the plate portion 220 of the intermediate layer 200 is provided on the first back wall 130 of the first layer 100, and can protect the first back wall 130.

In one embodiment, the corners 210 of the intermediate layer 200 are spaced apart. As shown in fig. 3, the intermediate layer 200 has four corners 210, and the four corners 210 are spaced apart. That is, the space 230 is formed between adjacent corner portions 210. The intermediate layer 200 may be made of a hard material, and the hard material may be a metal material. Therefore, the protective shell has a good protective effect, the material consumption of the hard middle layer 200 is reduced, the weight of the protective shell is reduced, and the protective shell has a good protective effect and a light effect.

As shown in fig. 4, fig. 4 is an exploded schematic view of a protective shell according to an embodiment of the present invention. The protective case includes a first layer 100, a second layer 300, and an intermediate layer 200. Wherein the structure of the intermediate layer 200 is the same as the structure of the intermediate layer 200 in the embodiment shown in fig. 3. As shown in fig. 4, the intermediate layer 200 includes corner portions 210 and plate portions 220 connecting the corner portions 210. The corner portion 210 is disposed on the first sidewall 120 of the first layer 100, and the plate portion 220 is disposed on the first back wall 130 of the first layer 100. Specifically, the first layer 100 may be a flat rectangular parallelepiped as a whole, and twelve edges of the rectangular parallelepiped form eight corners in total. The middle layer 200 has four corners 210, and each corner 210 wraps two corners of the first layer 100 disposed in the thickness direction. Thus, when the protective case is dropped, all eight corners are protected by the corner portions 210 of the intermediate layer 200. Further, the plate portion 220 of the intermediate layer 200 is provided on the first back wall 130 of the first layer 100, and can protect the first back wall 130. The corners 210 of the intermediate layer 200 are spaced apart. The intermediate layer 200 has four corners 210, the four corners 210 being spaced apart. That is, the space 230 is formed between adjacent corner portions 210. The intermediate layer 200 may be made of a hard material, and the hard material may be a metal material. Therefore, the protective shell has a good protective effect, the material consumption of the hard middle layer 200 is reduced, the weight of the protective shell is reduced, and the protective shell has a good protective effect and a light effect.

As shown in fig. 4, the first layer 100 is different from the first layer 100 in the embodiment shown in fig. 3 in that four second fixing grooves 150 are provided on four corners of the first layer 100 in the embodiment shown in fig. 4, and the second fixing grooves 150 are used to fix four corners 210 of the intermediate layer 200. The second layer 300 in the embodiment shown in fig. 4 includes a second sidewall 310 and a second back wall 320, which is different from the second layer 300 in the embodiment shown in fig. 3 in that the second sidewall 310 and the second back wall 320 in fig. 3 are integrally formed, i.e. the second sidewall 310 and the second back wall 320 in fig. 3 are both made of soft material such as TPU. As shown in fig. 4, the second side wall 310 shown in fig. 4 may be a soft layer made of TPU (thermoplastic polyurethane), and the second back wall 320 may be a hard layer made of hard material such as PC (polycarbonate plastic). The second layer 300 of the protective case in the embodiment shown in fig. 4 adopts a soft-hard bonded structure. The soft second sidewall 310 plays a role of buffering and absorbing shock. The rigid second back wall 320 serves as a support to prevent the protective case from being deformed by an impact at the second back wall 320. The second sidewall 310 and the second back wall 320 shown in fig. 4 may be connected by an in-mold injection molding or the like.

As shown in fig. 5, fig. 5 is a schematic diagram of an explosive structure of a protective shell according to an embodiment of the present invention. The protective case includes a first layer 100, an intermediate layer 200, and a second layer 300. The first layer 100 includes a first sidewall 120 and a first back wall 130 connecting the first sidewall 120. The embodiment shown in fig. 5 is different from the first layer 100 of the embodiment shown in fig. 1 in that, in the embodiment shown in fig. 5, a third fixing groove 160 having a ring shape is provided at a connection position of the first sidewall 120 and the first back wall 130. The intermediate layer 200 is ring-shaped. The middle layer 200 is installed in the third fixing groove 160.

The second layer 300 in the embodiment shown in fig. 5 has substantially the same structure as the second layer 300 in the embodiment shown in fig. 3. The second layer 300 has a second sidewall 310 and a second back wall 320 connecting the second sidewall 310. The second sidewall 310 is disposed on the first sidewall 120. The second back wall 320 is disposed on the first back wall 130. The structure of the first layer 100 is substantially the same as that of the second layer 300, for example, the first layer 100 is substantially rectangular parallelepiped, and the second layer 300 is also substantially rectangular parallelepiped; the first layer 100 is provided with a mounting groove 110 for mounting an article, and the second layer 300 is provided with a groove structure for mounting the first layer 100. The dimensions of the second layer 300 may be slightly larger than the dimensions of the corresponding locations of the first layer 100 to enable the first layer 100 to fit within the channel structure of the second layer 300. That is, the second layer 300 may wrap around the first layer 100. Therefore, when the protective shell is dropped, the opening of the first layer 100 except the mounting groove 110 is exposed to the outside, and other parts of the first layer 100 are wrapped by the second layer 300, so that the second layer 300 can play a role of protecting the first layer 100 in multiple directions.

In one embodiment, the intermediate layer 200 is a plate-like structure, the intermediate layer 200 being disposed at the bottom of the first layer 100, in particular, the intermediate layer 200 being disposed between the first layer 100 and the second layer 300.
