[0030] The utility model provides an electronic device protective shell, referring to Figure 1-6 The electronic device protective shell includes a back plate 10 and a frame 20 connected to the edge of the back plate 10. The frame 20 includes a first inner wall 21 and a second inner wall 22 located on opposite sides of the back plate 10. The first inner wall 21 is inclined relative to the back plate 10 toward the direction of the back plate 10.

[0031] Specifically, when the electronic device 40 is assembled on the electronic device protective case, since the first inner wall 21 is inclined toward the back plate 10, the first inner wall 21 and the second inner wall 22 on the opposite sides of the back plate 10 can be clamped on the corresponding side walls of the electronic device 40. The utility model uses the first inner wall 21 and the second inner wall 22 to clamp the side walls of the electronic device 40 to achieve assembly of the electronic device 40 and the electronic device protective case. Therefore, when the electronic device protective case of this embodiment is used, there will be no situation where the electronic device protective case blocks the screen of the electronic device 40. In addition, the first inner wall 21 is inclined in this embodiment to enable the first inner wall 21 and the second inner wall 22 to clamp the electronic device 40, which can also ensure the stability of the electronic device 40 when it is assembled on the electronic device protective case.

[0032] It can be understood that the first inner wall 21 can be in contact with the side wall of the electronic device 40 through the wall surface of the first inner wall 21 (see Figure 3), the second inner wall 22 can, for example, contact the side wall of the electronic device 40 through the wall surface of the second inner wall 22, and a certain friction force can be generated between the first inner wall 21 and the second inner wall 22 and the corresponding side walls of the electronic device 40, thereby realizing the assembly of the electronic device protective shell and the electronic device 40.

[0033] It should be noted that the frame 20 may be entirely located on two opposite sides of the back plate 10, or part of the frame 20 may be located on two opposite sides of the back plate 10, for example, in the width direction of the electronic device protective shell, the frame 20 is located on two opposite sides of the back plate 10, and / or, in the length direction of the electronic device protective shell, the frame 20 is located on two opposite sides of the back plate 10. The first inner wall 21 and the second inner wall 22 may be located on two opposite sides of the back plate 10 in the width direction of the electronic device protective shell, or may be located on two opposite sides of the back plate 10 in the length direction of the electronic device protective shell. The frame 20 located on two opposite sides of the back plate 10 in the width direction of the electronic device protective shell and the frame 20 located on two opposite sides of the back plate 10 in the length direction of the electronic device protective shell may be integrally formed or may be independent of each other.

[0034] In some embodiments, reference Figure 4 or Figure 6 The frame 20 includes a protrusion 201, which is protruded and formed on the first inner wall 21 and / or the second inner wall 22 (that is, the protrusion 201 is protruded and formed on the first inner wall 21, or the protrusion 201 is protruded and formed on the second inner wall 22, or the protrusion 201 is not only protruded and formed on the first inner wall 21 but also on the second inner wall 22), and the protrusion 201 is used to contact the side wall of the electronic device 40. The provision of the protrusion 201 can further increase the clamping force of the first inner wall 21 and the second inner wall on the electronic device 40, so that the first inner wall 21 and the second inner wall clamp the electronic device 40 more firmly, and because the protrusion 201 contacts the side wall of the electronic device 40, the screen of the electronic device 40 will not be blocked.

[0035] In some embodiments, reference Figure 4 When the protrusion 201 is arranged on the first inner wall 21, along the thickness direction of the electronic device protective shell, the protrusion 201 is located in the middle position of the first inner wall 21 or the protrusion 201 is located at the end of the first inner wall 21 away from the back plate 10; in addition, when the protrusion 201 is arranged on the second inner wall 22, along the thickness direction of the electronic device protective shell, the protrusion 201 is located in the middle position of the second inner wall 22 or the protrusion 201 is located at the end of the second inner wall 22 away from the back plate 10.

[0036] Take the protrusion 201 protruding relative to the first inner wall 21 as an example: Figure 4After the electronic device 40 and the electronic device protective shell are assembled, the protrusion 201 will support the side wall of the electronic device 40, and the frame 20 is usually deformable. Therefore, in the above-mentioned thickness direction, when the protrusion 201 is closer to the back plate 10, the protrusion 201 is more likely to push the frame 20 away from the electronic device 40, resulting in the frame 20 not being able to clamp the electronic device 40 well, and then causing the electronic device 40 to easily fall off the electronic device protective shell. Therefore, in this embodiment, setting the protrusion 201 in the middle of the inner wall or at an end away from the back plate 10 can make it difficult for the electronic device 40 to fall off the electronic device protective shell, so that the stability of the electronic device 40 and the electronic device protective shell after assembly is higher.

[0037] It can be understood that the frame 20 can usually be deformed. For example, when assembling the electronic device 40 with the electronic device protective case, the frames 20 on opposite sides of the back panel 10 can be bent outward to expand the distance between the first inner wall 21 and the second inner wall 22, so that the electronic device 40 can be installed in the electronic device protective case.

[0038] In some embodiments, reference Figure 6 The frame 20 includes a plurality of protrusions 201. When the protrusions 201 are disposed on the first inner wall 21, the plurality of protrusions 201 may be disposed at intervals on the first inner wall 21; in addition, when the protrusions 201 are disposed on the second inner wall 22, the plurality of protrusions 201 may also be disposed at intervals on the second inner wall 22. In this way, the friction between the protrusions 201 and the side wall of the electronic device 40 may be increased, thereby improving the stability of the electronic device 40 when assembled on the electronic device protective shell.

[0039] Specifically, take the protrusion 201 set on the first inner wall 21 as an example: referring to the figure, when the first inner wall 21 and the second inner wall 22 are located on opposite sides of the back plate 10 in the length direction of the electronic device protective shell, multiple protrusions 201 may be distributed at intervals along the width direction and / or thickness direction of the electronic device protective shell; when the first inner wall 21 and the second inner wall 22 are located on opposite sides of the back plate 10 in the width direction of the electronic device protective shell, multiple protrusions 201 may be distributed at intervals along the length direction and / or thickness direction of the electronic device protective shell.

[0040] Similarly, when the protrusion 201 is arranged on the second inner wall 22: when the first inner wall 21 and the second inner wall 22 are located on opposite sides of the back plate 10 in the length direction of the electronic device protective case, multiple protrusions 201 may be distributed at intervals along the width direction and / or thickness direction of the electronic device protective case; when the first inner wall 21 and the second inner wall 22 are located on opposite sides of the back plate 10 in the width direction of the electronic device protective case, multiple protrusions 201 may be distributed at intervals along the length direction and / or thickness direction of the electronic device protective case.

[0041] It is understandable that the surface of the protrusion 201 can be, for example, a curved surface, so that when the electronic device 40 and the electronic device protective case are assembled, the risk of the protrusion 201 scratching the electronic device 40 can be reduced.

[0042] In some embodiments, reference Figure 5 The first inner wall 21 includes an inclined portion 211 and a fitting portion 212. The inclined portion 211 is inclined toward the back plate 10. The fitting portion 212 is located at one end of the inclined portion 211 away from the back plate 10. The thickness of the frame 20 at the inclined portion 211 is less than the thickness of the frame 20 at the fitting portion 212.

[0043] When the electronic device 40 is assembled on the electronic device protective case, the first inner wall 21 can be attached to the side walls of the electronic device 40 on opposite sides together with the second inner wall 22 through the fitting portion 212 to achieve clamping of the electronic device 40. In addition, since the fitting portion 212 is located at the end of the inclined portion 211 away from the back plate 10, when the electronic device 40 is assembled on the electronic device protective case, the fitting portion 212 is closer to the side wall of the electronic device 40, so that the fitting strength between the fitting portion 212 and the side wall of the electronic device 40 is higher.

[0044] Further, in some embodiments, reference Figure 5 The surface of the fitting portion 212 is perpendicular to the back plate 10, so that the contact area between the fitting portion 212 and the side wall of the electronic device 40 can be increased, thereby increasing the friction between the fitting portion 212 and the side wall of the electronic device 40, thereby improving the stability of the electronic device 40 when assembled on the electronic device protective case.

[0045] In some embodiments, reference Figure 2 , the distance between the end of the first inner wall 21 away from the back plate 10 and the end of the second inner wall 22 away from the back plate 10 is smaller than the distance between the end of the first inner wall 21 close to the back plate 10 and the end of the second inner wall 22 close to the back plate 10. In this way, the end of the first inner wall 21 away from the back plate 10 can better contact the side wall of the electronic device 40, so that the electronic device can be better clamped between the first inner wall 21 and the second inner wall 22.

[0046] In some embodiments, reference Figure 4 or Figure 5The frame 20 includes a first part 23 and a second part 24 that are connected to each other. The hardness of the first part 23 is greater than that of the second part 24. The first part 23 is formed by extending upward from the back plate 10 along the direction from one end of the first inner wall 21 close to the back plate 10 to the end of the first inner wall 21 away from the back plate 10. Specifically, the first part 23 and the back plate 10 are integrally formed, and the material of the back plate 10 and the first part 23 is, for example, PC, and the material of the second part 24 is, for example, TPU. Such a setting can make the elastic restoring force of the second part 24 (that is, the elastic force of the frame 20 after the elastic deformation (the frame 20 is under the same deformation displacement)) higher when the elastic deformation occurs. By setting the hardness of the first part 23 to be greater than that of the second part 24, the elastic force of the frame 20 is increased, so that the frame 20 clamps the electronic device 40 more firmly.

[0047] refer to Figure 4 or Figure 5 , the positional relationship between the first portion 23 and the second portion 24 is not limited, for example Figure 4 , the first part 23 is interspersed in the second part 24, for example Figure 5 , the first part 23 is located on one side of the second part 24.

[0048] It can be understood that the first portion 23 and the second portion 24 can be formed by secondary injection molding.

[0049] Further, in some embodiments, reference Figure 4 or Figure 5 The distance from one end of the first part 23 away from the back plate 10 to the back plate 10 is greater than or equal to half the distance from one end of the frame 20 away from the back plate 10 to the back plate 10. Since the hardness of the first part 23 is greater than that of the second part 24, the setting of this embodiment makes the elastic restoring force of the frame 20 better.

[0050] In some embodiments, reference Figure 2 The second inner wall 22 is inclined relative to the back plate 10 in the direction of the back plate 10 , so that the clamping force of the first inner wall 21 and the second inner wall 22 on the electronic device 40 can be increased, and the stability of the electronic device protective shell and the electronic device 40 during assembly can be improved.

[0051] In some embodiments, reference Figure 1-5 , the included angle α between the first inner wall 21 and the back plate 10 is less than 90° and greater than or equal to 85°.

[0052] Specifically, Table 1 is a statistical table of the assembly status of the electronic device protective case and the electronic device 40 when the angle α between the first inner wall 21 and the back plate 10 of the embodiment of the utility model is at different angles. It can be seen from Table 1 that during the assembly of the electronic device protective case with the electronic device 40: when the angle α between the first inner wall 21 and the back plate 10 is 90°, the first inner wall 21 and the second inner wall 22 cannot clamp the electronic device 40; when the angle α is 89°, the first inner wall 21 and the second inner wall 22 can clamp the electronic device 40; when the angle α is less than 85°, the assembly between the electronic device 40 and the electronic device protective case begins to become difficult, which will bring difficulties to the user in assembling the electronic device 40 and the electronic device protective case, affecting the user's experience.

[0053]

[0054] Table 1

[0055] Therefore, the angle α in this embodiment is optimally less than 90° and greater than 85°, and the electronic device 40 and the electronic device protective shell are easy to assemble, and the electronic device 40 and the electronic device protective shell fit well, and the electronic device 40 will not fall off.

[0056] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
