DETAILED DESCRIPTION

[0029] In order to make the above-mentioned purpose, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0030] In order to make the above-mentioned purpose, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0031] It should be noted that the terms "first", "second", and the like in the description and in the claims of the utility model of the present application and the above-mentioned drawings are used to distinguish similar objects and do not have to be used to describe a specific order or sequence. It should be understood that the terms used in this way can be interchanged under appropriate circumstances, so that the utility model embodiments described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product or device including a series of steps or units does not have to be limited to those steps or units clearly listed, but can include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0032] It should also be noted that the division of multiple embodiments in the utility model is only for the convenience of description and should not constitute a special limitation. The features in various embodiments can be combined and mutually referenced without contradiction.

[0033] Referring to Figure 1 , the utility model embodiment provides a protective shell, including shell 10 and cladding 20. Referring to Figure 2 and Figure 3 , the shell 10 includes backboard 11 and side frame 12, and the side frame 12 is connected to the backboard 11 and is surrounded together with the backboard 11 to form a containing cavity 13. The cladding 20 includes main body 21 and extension 22, the main body 21 covers the side of the backboard 11 away from the containing cavity 13, and the extension 22 extends from the periphery of the main body 21 to the side frame 12 and covers at least part of the side frame 12. Wherein, the material hardness of the cladding 20 is greater than the material hardness of the shell 10.

[0034] For example, the shell 10 adopts TPU, TPE, silica gel and other relatively soft materials, and the cladding 20 adopts PC and other relatively hard materials. For example, the material hardness range of the shell 10 is Shore Hardness 60HA~60HD. The material hardness range of the cladding 20 is Shore Hardness 70HD~90HD. Wherein, the shell 10 and the cladding 20 can be connected into one body through a sleeve process or ultrasonic welding process, etc.

[0035] The side frame 12 extends towards the side of the back plate 11 close to the accommodating cavity 13. The back plate 11 is consistent with the overall shape of the electronic device, and is generally a rectangular with rounded corners, having four edges. The side frame 12 is mainly provided with four parts surrounding the four edges of the back plate 11. According to the conventional use direction of the electronic device, the four parts of the side frame 12 can be respectively referred to as a top part, a bottom part 122 and two side parts. The top part corresponds to the top edge of the electronic device, and the bottom part 122 corresponds to the bottom edge of the electronic device. The shape of the main body part 21 is basically consistent with that of the back plate 11. For example, a camera avoiding hole is formed in the back plate 11, and the main body part 21 covers the part of the back plate 11 except the camera avoiding hole, that is, the main body part 21 exposes the camera avoiding hole. The extension part 22 extends towards the side of the main body part 21 close to the back plate 11 (the accommodating cavity 13). The extension part 22 can respectively extend from the four edges of the main body part 21 to cover the four parts of the side frame 12, of course, the extension part 22 can completely cover or partially cover each of the four parts of the side frame 12.

[0036] When the protective shell provided by the present embodiment is used, the protective shell is sleeved on the electronic device, so that the electronic device is located in the accommodating cavity 13. In the present embodiment, the cladding layer 20 with a relatively high material hardness is covered on the shell 10 with a relatively low material hardness, so that when the electronic device sleeved with the protective shell of the present embodiment falls or is impacted, the cladding layer 20 is first contacted, and the cladding layer 20 is not easy to be deformed and press the electronic device due to the high hardness, and the shell 10 on the inner side has a soft material and can effectively disperse the impact force, so that the cladding layer 20 is not easy to be broken, and the impact force is not transmitted to the electronic device, so that a better protection effect can be achieved on the electronic device, and the protective shell itself is also not easy to be broken and damaged, and has a longer service life.

[0037] In some embodiments, referring to Figure 2 , Figure 3 and Figure 5 , the side frame 12 has an edge part 121 located at the end of the side frame 12 away from the back plate 11, and the surface of the edge part 121 away from the accommodating cavity 13 is not covered by the cladding layer 20. In a specific embodiment, the edge part 121 is a whole structure surrounding the accommodating cavity 13, and of course, it can also be only part of the edge of the side frame 12. The cladding layer 20 does not cover the edge part 121, that is, at least part of the edge of the end of the side frame 12 away from the back plate 11 is not covered by the cladding layer 20 (specifically, the extension part 22), that is, the extension part 22 does not completely extend to the end of the side frame 12 away from the back plate 11. So that only the soft material is left on the edge part 121 not covered by the cladding layer 20, so that the user can use fingers to pick up the edge part 121 to make the edge part 121 deform to separate from the mobile phone, so as to take off the protective shell, so that the disassembly of the protective shell is more easy and convenient.

[0038] In some embodiments, the edge portion 121 has a width greater than or equal to 2 mm in a direction from an end of the side frame 12 away from the back plate 11 to an end of the side frame 12 connected to the back plate 11, i.e. the extending direction of the side frame 12. The edge portion 121 has a proper width to ensure that it can be deformed without affecting the protection effect. When the width of the edge portion 121 is small, e.g. less than 2 mm, the edge portion is not easy to deform, which makes it difficult for a user to remove the protective case from the mobile phone. The edge portion 121 can have different widths in different regions of the side frame 12, which can be selected according to actual needs.

[0039] In some embodiments, the side frame 12 has an inner surface 122S on a side facing the accommodating cavity 13. The distance between the surface of the accommodating cavity 13 away from the edge portion 121 and the inner surface 122S is a first thickness, and the distance between the surface of the accommodating cavity 13 away from the extending portion 22 and the inner surface 122S is a second thickness. The first thickness is equal to the second thickness. Referring to Figure 4 and Figure 5 In short, the surface of the edge portion 121 away from the accommodating cavity 13 is flush with the surface of the extending portion 22 away from the accommodating cavity 13. That is, the outer surface of the edge portion 121 is flush with the outer surface of the extending portion 22, so that the overall outer side of the protective case is flat without steps, which is more comfortable to use and will not hurt the hand.

[0040] Referring to Figure 5 In some embodiments, the end of the side frame 12 away from the back plate 11 is curved towards the inside of the accommodating cavity 13. Alternatively, the end of the side frame 12 away from the back plate 11 is formed with a protrusion extending towards the inside of the accommodating cavity 13. The end of the side frame 12 away from the back plate 11 can thus clasp the edge of the electronic device inside the accommodating cavity 13, which can prevent the protective case from falling off during use.

[0041] In some embodiments, referring to Figure 3 The bottom 122 is provided with a functional avoiding hole 1221. The extending portion 22 is provided with a first opening 221 corresponding to the functional avoiding hole 1221, referring to Figure 2The first opening 221 on the bottom 122 covers the functional avoiding hole 1221 in the orthographic projection, that is, the functional avoiding hole 1221 is exposed to the extension 22 through the first opening 221. Specifically, the bottom of the electronic device is usually provided with a charging port, a speaker hole, and a microphone hole, and corresponding avoiding is needed on the protective shell to ensure the normal use of the electronic device. The functional avoiding hole 1221 can be a charging avoiding hole, a speaker avoiding hole, or a microphone avoiding hole. A plurality of functional avoiding holes 1221 can be provided corresponding to a plurality of functional holes, or an integral functional avoiding hole 1221 can be provided corresponding to a plurality of functional holes. The first opening 221 on the bottom 122 covers the functional avoiding hole 1221 in the orthographic projection, that is, the functional avoiding hole 1221 is exposed from the first opening 221, that is, the extension 22 does not cover the functional avoiding hole 1221, and the area of the first opening 221 is larger, and more area of the bottom 122 can be exposed and thus deformation can occur more easily. At this time, the user can disassemble the protective shell through the bottom 122. In combination with the foregoing embodiments, the width of the edge portion 121 of the bottom 122 can be greater than the width of the edge portion 121 of the two side portions or the top portion, and the edge portion 121 of the bottom 122 can surround the functional avoiding hole 1221.

[0042] In some embodiments, specifically referring to Figure 2 and Figure 3 The number of functional avoiding holes 1221 is a plurality, and the bottom 122 has an isolation area 1222 between adjacent two functional avoiding holes 1221, which is exposed outside the extension 22 through the first opening 221, that is, the extension 22 does not cover the isolation area 1222. The area corresponding to the plurality of functional avoiding holes 1221 is not covered by the extension 22, and deformation can occur more easily, facilitating disassembly of the protective shell.

[0043] In some embodiments, the thickness of the cladding layer 20 is greater than or equal to the thickness of the shell 10. For example, the material thickness of the shell 10 ranges from 1.2 to 1.5 mm, and the thickness of the cladding layer 20 ranges from 1.2 to 2.0 mm. In some embodiments, the overall thickness of the cladding layer 20 is greater than the overall thickness of the shell 10. If the thicknesses are not uniform, the thickness of a certain area of the cladding layer 20 is compared with the thickness of the area covered by the area on the shell 10. For example, the thickness of the main body portion 21 is greater than or equal to the thickness of the back plate 11. The thickness of the extension 22 is greater than or equal to the thickness of the side frame 12. It is not required that the thickness of the extension 22 is greater than the thickness of the back plate 11. The overall thickness of the cladding layer 20 is set to be relatively thick, which can better prevent the cladding layer 20 from breaking and make the cladding layer 20 easier to be manufactured into a shape.

[0044] In some embodiments, the thickness of the main part 21 is greater than the thickness of the extension part 22, and the difference is less than or equal to 0.2 mm. That is, the thickness of the cladding layer 20 on the back plate 11 is greater than the thickness of the cladding layer 20 on the side frame 12, so that the back plate 11 is better protected, and the overall hardness of the side of the protective shell is not too large, facilitating the removal of the protective shell. In some specific embodiments, the thickness of the main part 21 is in the range of 1.2-2.0 mm, and the thickness of the extension part 22 is in the range of 1.0-1.8 mm.

[0045] In some embodiments, the side frame 12 is provided with a key part 123, and the extension part 22 is arranged around the periphery of the key part 123. It can also be said that the extension part 22 has a second opening 222, and the edge of the extension part 22 located in the second opening 222 surrounds the key part 123. The key part 123 is exposed outside the extension part 22 through the second opening 222 and is not covered by the extension part 22. At this time, the problem that the key part 123 is covered and affects the operation can be avoided, and the deformation ability of the periphery of the key part 123 can also be reduced through the extension part 22, so that the user operates the key part 123 and the side frame 12 does not deform with the key part 123, and the operation is more sensitive. In some embodiments, the distance between the surface away from the accommodating cavity 13 of the key part 123 and the inner surface 122S is greater than or equal to the distance between the surface away from the accommodating cavity 13 of the extension part 22 and the inner surface 122S, which facilitates the user to contact the key part 123 and facilitates the operation.

[0046] Referring to Figure 6 The protective shell provided by the embodiments of the present application further comprises a sandwich layer 30, which is located between the cladding layer 20 and the shell 10. The sandwich layer 30, for example, comprises a heat dissipation material layer such as a graphene layer and the like for heat dissipation, and can also comprise a decorative layer for decoration. The sandwich layer 30 can be a separate material layer clamped between the cladding layer 20 and the shell 10, and in some embodiments, the sandwich layer 30, the cladding layer 20 and the shell 10 are integrally formed. The sandwich layer 30 can also be a coating layer coated on the outer surface of the shell 10 (towards the surface of the cladding layer 20) or the inner surface of the cladding layer 20 (towards the surface of the shell 10), and the present embodiment is not limited.

[0047] Referring to Figure 7 The protective shell provided by the embodiments of the present application further comprises a magnetic attraction member 40, which is clamped between the back plate 11 and the main part 21. The magnetic attraction member 40, for example, is a ring-shaped magnet, that is, the whole is ring-shaped or is arranged in a ring shape by a plurality of magnets, which corresponds to the wireless charging coil area of the electronic device, so as to enhance the magnetic attraction connection with the wireless charger. The magnetic attraction member 40, for example, can also comprise a positioning magnet, which can realize the function of automatically adjusting the adsorption angle of the electronic device when connected with the wireless charger.

[0048] The protective shell provided by the embodiment of the utility model further comprises a protective coating, and the protective coating is located on the side of the cladding layer away from the shell. The protective coating can comprise a scratch-resistant layer, a fingerprint-resistant layer and the like, and the protective coating can be multilayered, and the materials of the multilayered protective coating can be different, so as to realize protection with different functions. Of course, the protective coating can also be a single-layered coating.
