[0002] With the continuous development of technology, the popularity of electronic devices such as mobile phones, tablet computers, and power banks has been increasing. Users protect electronic devices such as mobile phones by sleeving a protective case on the electronic device. The protective case is usually made of materials such as TPU (thermoplastic polyurethane elastomer) and silica gel. Through the characteristics of its materials, when the electronic device drops or collides, a part of the impact force can be offset by the deformation of the protective case material, thereby playing a certain protective role. However, relying solely on the deformation of the protective case material itself, the achieved protective effect is limited. Unless the thickness of the protective case is set to be relatively thick, but this will make the protective case of the electronic device heavier, thus not meeting the requirements of portability and lightness of the electronic device and affecting the user experience.

Detailed implementation manners

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0027] Refer to Figures 1 to 4 , a protective case 10 for an electronic device provided by an embodiment of the present invention specifically may include, for example: a back plate 100 and a side frame 200.

[0028] The side frame 200 is connected to the back plate 100, and the side frame 200 and the back plate 100 form an electronic device accommodation cavity 101 for accommodating an electronic device so that the electronic device protective case 10 can be sleeved on the electronic device. Referring again to Figure 1 , the side frame 200 has opposite ends 201 along the length direction, and an airbag cavity 202 is provided at the ends 201. In this embodiment, the ends 201 can be, for example, the positions where the two short sides of the side frame 200 are located. The ends 201 not only refer to the two short sides, but can also, for example, include the positions at the long sides connected to the short sides. Of course, this embodiment is not limited thereto. Since when the electronic device drops or collides, the four corners of the electronic device or the bottom and top of the electronic device are more likely to be damaged by external forces, by providing the airbag cavity 202 at the two ends 201 of the side frame 200, the electronic device protective case 10 can form better protection for the electronic device through the airbag cavity 202.

[0029] The electronic device protective case 10 provided in this embodiment is provided with an airbag cavity 202 at the end 201 of the side frame 200. Through the setting of the airbag cavity 202 at the end 201, when the electronic device drops or collides, it can play a protective role for the electronic device, which can improve the protection ability of the electronic device protective case 10 for the electronic device, and will not increase the overall thickness of the protective case, so that the electronic device sleeved with the electronic device protective case 10 meets the requirements of portability and lightness, and improves the user experience.

[0030] Referring to Figure 3 and Figure 4 , the side frame 200 can, for example, include an inner side frame 210 and an outer side frame 220. The inner side frame 210 and the outer side frame 220 are connected, and the outer side frame 220 is provided on the side of the inner side frame 210 away from the electronic device accommodation cavity 101, that is, the inner side frame 210 is arranged close to the electronic device accommodation cavity 101, and the outer side frame 220 is arranged on the outer side of the inner side frame 210. The airbag cavity 202 is formed between the inner side frame 210 and the outer side frame 220.

[0031] Referring to Figure 3 and Figure 5 , a recessed airbag wall 222 is provided on the inner side wall of the end 201 of the outer side frame 220. The inner side frame 210 and the outer side frame 220 are connected, so that the airbag wall 222 and the inner side frame 210 enclose to form the airbag cavity 202. The airbag wall 222 forms a groove structure by recessing. The surface of the inner side frame 210 close to the outer side frame 220 can be, for example, a flat structure. Through the setting of the airbag wall 222, the airbag cavity 202 is formed between the inner side frame 210 and the outer side frame 220, and the surface of the inner side frame 210 close to the electronic device accommodation cavity 101 can be flat, which can improve the fitting degree of the electronic device protective case 10 and the electronic device.

[0032] Referring again to Figure 3 , the edge of the inner side frame 210 connecting the outer side frame 220 has a first connecting portion 211, that is, the edge of the airbag wall 222 has a first connecting portion 211, and the edge of the outer side frame 220 has a second connecting portion 221. The second connecting portion 221 is stacked on the side of the first connecting portion 211 away from the electronic device accommodating cavity 101, and the first connecting portion 211 and the second connecting portion 221 are hermetically connected. Through the arrangement of the first connecting portion 211 and the second connecting portion 221, the airbag cavity 202 is formed by a simple structure, and the second connecting portion 221 is stacked on the side of the first connecting portion 211 away from the electronic device accommodating cavity 101, making the connection tight and convenient for production. The second connecting portion 221 and the first connecting portion 211 can be fixedly connected by, for example, die cutting, injection molding, pasting and other methods.

[0033] Further, in an embodiment of the present embodiment, a connecting groove may be provided on the second connecting portion 221. Specifically, for example, a connecting groove is provided on the side of the second connecting portion 221 connecting the first connecting portion 211, and the first connecting portion 211 is accommodated in the connecting groove. Through the arrangement of the connecting groove, while reducing the thickness of the second connecting portion 221, the surface of the side frame 200 close to the electronic device accommodating cavity 101 can be made flat, and the fitting degree between the electronic device protective case 10 and the electronic device can be improved.

[0034] The side frame 200 has two first side edges extending in the width direction and two second side edges extending in the length direction. In an embodiment of the present embodiment, the airbag cavity 202 may be provided, for example, on the two first side edges and extend respectively toward the two second side edges. That is, the airbag cavity 202 is located on the two first side edges and on a partial area where the two second side edges are connected to the two first side edges. Further, the total length of the airbag cavity 202 accounts for 30% - 50% of the total length of the side frame 20 . In the present embodiment, the airbag cavity 202 may also extend, for example, to the corner position where the first side edge is connected to the second side edge. Through such an arrangement, the protection ability of the electronic device protective case 10 can be improved.

[0035] See Figure 4 , Figure 6 and Figure 7, the outer frame 220 may be provided with a holding portion 223, for example. The holding portion 223 may be provided in the length direction, for example. The holding portion 223 may be provided on one second side of the outer frame 220, or may be provided on two second sides. Of course, this embodiment is not limited thereto. The electronic device protective case 10 may further include an auxiliary holding member 300, for example. The auxiliary holding member 300 is fixedly connected to the holding portion 223 of the outer frame 220. Similarly, the auxiliary holding member 300 may include one or two, for example. The auxiliary holding member 300 may be provided on one second side length of the outer frame 220, or may be provided on two second sides. In this embodiment, the outer frame 220 may be made of a soft material, and the auxiliary holding member 300 may also be made of a soft material. The soft material may be, for example, a silicone material, a rubber material, or may also be a TPU (thermoplastic polyurethane elastomer) material, etc.

[0036] Referring again to Figure 7 , the holding portion 223 may also be provided with a receiving groove 2231 that matches the auxiliary holding member 300, for example. The auxiliary holding member 300 is disposed in the receiving groove 2231. In an implementation manner of this embodiment, the surface of the auxiliary holding member 300 is flush with the surface of the outer frame 220. In another implementation manner of this embodiment, the surface of the auxiliary holding member 300 may be higher than the surface of the outer frame 220, for example. Through the receiving groove 2231, the thickness of the side frame 200 of the electronic device protective case 10 can be further reduced, and the holding feel can be further improved.

[0037] Referring again to Figure 6 , the auxiliary holding member 300 and the inner frame 210 are located on both sides of the outer frame 220, and the auxiliary holding member 300 is attached to the outer frame 220, and the outer frame 220 and the inner frame 210 are attached and connected. Through the three-layer structure attachment and connection, the strength of the side frame 200 can be further improved to further improve the protection ability of the electronic device protective case 10. Referring to Figure 8 , the auxiliary holding member 300 may also be provided with an anti-slip structure 301, for example. The anti-slip structure 301 may be a plurality of protrusions or a plurality of grooves provided on the surface of the auxiliary holding member 300, and the plurality of protrusions or the plurality of grooves are arranged on the surface of the auxiliary holding member 300. Through the setting of the anti-slip structure 301, the holding stability can be improved, and it can be avoided that the user drops the electronic device protective case 10, and the protection force can be further improved.
