[0035] The technical solution of the utility model is further elaborated in detail below in conjunction with the drawings and specific embodiments of the specification. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by technicians in the technical field of the utility model. The terms used herein in the specification of the utility model are only for the purpose of describing specific embodiments and are not intended to limit the utility model. In the following description, the expression "some embodiments" is involved, which describes a subset of all possible embodiments, but it should be understood that "some embodiments" can be the same subset or different subsets of all possible embodiments, and can be combined with each other without conflict.

[0036] It should also be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "inside", "outside", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only implementation method.

[0037] In the prior art, in order to ensure the stability and firmness of the bracket support, the bracket protective shell with integrated bracket function usually uses metal materials to make the bracket. Although the bracket made of metal materials has good supporting strength, when the wireless charging technology is used to charge electronic products, the bracket made of metal materials will reduce the transmission efficiency of the magnetic field energy. The reason is that the metal material will absorb the surrounding magnetic field energy, so that the magnetic field energy generated by the transmitting coil inside the wireless charging device cannot be effectively transmitted to the receiving coil inside the electronic product, thereby affecting the wireless charging efficiency. In addition, the bracket made of metal materials will generate heat in the process of absorbing the surrounding magnetic field energy, which will cause the temperature of the bracket and its surrounding areas to rise, which will have an adverse effect on the performance of the wireless charging device and the electronic components in the electronic product, further reducing the wireless charging efficiency, and even causing the problem of charging interruption.

[0038] Please refer to the attached Figure 1 and attached Figure 2An embodiment of the utility model provides a bracket protective shell, which includes a shell 30 and a bracket assembly 10. The bracket assembly 10 includes a base 11 and a support member 12 rotatably connected to the base 11; the base 11 includes a metal part 111 and a non-metal part 112 connected to the metal part 111. The metal part 111 is rotatably connected to the support member 12, and the base 11 is connected to the shell 30. Among them, the metal part 111 is a part made of metal material, which can be made of pure metal material or alloy material; the non-metal part 112 is a part made of non-metal material, which can be made of plastic, ceramic or other composite materials. The metal part 111 provides support strength and connection strength for the support member 12 to ensure the stability and firmness of the support of the support member 12. The non-metal part 112 reduces the loss of magnetic field energy transmission and the interference to the magnetic field energy transmission during wireless charging.

[0039] The base 11 in this embodiment includes a metal part 111 and a non-metal part 112 connected to the metal part 111. The metal part 111 is rotatably connected to the support member 12. On the one hand, the metal part 111 can provide the strength and stability required by the support member 12 to ensure the firmness of the connection between the support member 12 and the base 11. On the other hand, the non-metal part 112 can help reduce the loss of magnetic field energy transmission and heat generation during wireless charging, thereby improving the wireless charging efficiency.

[0040] In some optional embodiments, the metal part 111 and the non-metal part 112 are integrally formed by injection molding; it can be explained that the metal part 111 and the non-metal part 112 are integrally formed by injection molding, which means that in the injection molding process, the metal part 111 is first molded, and then the metal part 111 is placed in the mold for molding the base 11, and the metal part 111 and the non-metal part 112 are injection molded into a whole at one time, thereby improving the overall stability and durability of the base 11. In some other optional embodiments, the metal part 111 and the non-metal part 112 are assembled and connected, and it can be explained that the metal part 111 and the non-metal part 112 are assembled and connected, which means that the metal part 111 and the non-metal part 112 are manufactured separately, and then assembled and spliced ​​by one or more combinations of connection methods such as welding, riveting, threaded connection, snap-fit ​​or bonding to form the base 11.

[0041] Please refer to the attached Figure 3In a specific example, the metal part 111 is provided with a first connection structure 1111, and the non-metal part 112 is provided with a second connection structure 1121, and the metal part 111 is firmly connected to the non-metal part 112 through the connection between the first connection structure 1111 and the second connection structure 1121. More specifically, one of the first connection structure 1111 and the second connection structure 1121 includes a card slot, and the other includes a card block, and / or, one of the first connection structure 1111 and the second connection structure 1121 includes a connection column, and the other includes a connection hole. Exemplarily, the first connection structure 1111 includes a card slot and a connection column, and the second connection structure 1121 includes a card block matching the card slot and a connection hole matching the connection column, and the metal part 111 is firmly connected to the non-metal part 112 through the card connection between the card slot and the card block and the plug-in connection between the connection column and the connection hole.

[0042] Please refer to the attached Figure 4 and attached Figure 5 In some optional embodiments, the base 11 is an annular structure, and the metal part 111 and the non-metal part 112 are arranged to form an annular structure, and the area surrounded by the annular structure is the wireless charging area 20. Among them, the annular structure can be a circular annular structure, or a square annular structure or a polygonal annular structure, which is not specifically limited here. It can be explained that the wireless charging area 20 refers to the area corresponding to the position where the wireless coil is set in the electronic product. A wireless transmitting coil and a wireless receiving coil are respectively arranged on both sides of the wireless charging area 20. The energy emitted by the wireless transmitting coil passes through the wireless charging area 20 and is received by the wireless receiving coil, thereby realizing the wireless charging function. In the design of the bracket protective shell, the position of the base 11 of the annular structure is set based on the position of the wireless coil in the electronic product. When the base 11 of the annular structure is installed on the bracket protective shell, the hollow part of the base 11 just corresponds to this wireless charging area 20, so that the bracket protective shell can cooperate with the wireless charging device during use to realize a convenient wireless charging function.

[0043] In some optional embodiments, the annular structure is a circular ring structure, and the metal portion 111 and the non-metal portion 112 are respectively a first arc structure and a second arc structure; in other words, the first arc structure is made of metal, the second arc structure is made of non-metal, and the first arc structure and the second arc structure are jointly arranged to form a circular ring structure. It should be further explained that the sum of the arc angle of the first arc structure and the arc angle of the second arc structure is less than or equal to 360°. It can be explained that when the sum of the arc angle of the first arc structure and the arc angle of the second arc structure is equal to 360°, the two ends of the first arc structure can be connected to the two ends of the second arc structure respectively, and at this time, the first arc structure and the second arc structure can form a completely closed circular ring structure; and when the sum of the arc angle of the first arc structure and the arc angle of the second arc structure is less than 360°, one end of the first arc structure is connected to one end of the second arc structure, and a notch is formed between the other end of the first arc structure and the other end of the second arc structure, and at this time, the first arc structure and the second arc structure form a semi-closed circular ring structure with a notch.

[0044] In some optional embodiments, the arc angle range of the first arc structure is 15°-355°. Figure 4 As shown by α in . Among them, the arc angle of the first arc structure is not less than 15° so that the first arc structure made of metal has a sufficient arc length, so as to provide an appropriate connection area when the support member 12 and the metal part 111 are rotatably connected, thereby ensuring the stability of the connection between the support member 12 and the metal part 111. The arc angle of the first arc structure is not greater than 355° so that the first arc structure made of metal cannot form a completely closed circular ring structure alone, thereby reserving space for the second arc structure made of non-metal. It should be pointed out that the arc angle range of the second arc structure is 0°-345°, preferably 5°-345°.

[0045] In some optional embodiments, the two opposite ends where the metal part 111 and the non-metal part 112 are connected include a starting end 113 and a terminating end 114; wherein the distribution forms of the starting end 113 and the terminating end 114 are various, illustratively, the starting end 113 and the terminating end 114 are arranged in parallel, or the starting end 113 and the terminating end 114 are arranged in non-parallel. It can be explained that the parallel arrangement of the starting end 113 and the terminating end 114 means that the end face corresponding to the starting end 113 and the end face corresponding to the terminating end 114 are arranged in parallel, that is, the two end faces do not have the possibility of intersecting. The non-parallel arrangement of the starting end 113 and the terminating end 114 means that the end face corresponding to the starting end 113 and the end face corresponding to the terminating end 114 are arranged in non-parallel, that is, the two end faces may intersect.

[0046] In some optional embodiments, the bracket assembly 10 further includes a rotating connection structure 13, which includes a first connection member 131 and a second connection member 132 hinged to the first connection member 131; specifically, the rotating connection structure 13 includes a rotating shaft, a first pivoting portion 1311 is provided at one end of the first connection member 131 close to the rotating shaft, the first pivoting portion 1311 is provided with a first shaft hole, a second pivoting portion 1321 is provided at one end of the second connection member 132 close to the rotating shaft, the second pivoting portion 1321 is provided with a second shaft hole, the rotating shaft is passed through the first shaft hole and the second shaft hole, and the end of the rotating shaft exceeds the first shaft hole and / or the second shaft hole, so as to realize the hinged connection between the first connection member 131 and the second connection member 132. In this embodiment, the supporting member 12 can be rotated relative to the metal part 111 by means of the rotating connection structure 13, allowing the user to flexibly adjust the angle and orientation of the supporting member 12 according to actual needs.

[0047] In a specific example, the metal part 111 is fixedly connected to the first connecting member 131, the support member 12 is fixedly connected to the second connecting member 132, and the support member 12 is rotatably connected relative to the metal part 111 through the hinge of the first connecting member 131 and the second connecting member 132. Specifically, the first connecting member 131 can be connected to the metal part 111 by welding, riveting, threading or bonding, and similarly, the second connecting member 132 can also be connected to the support member 12 by welding, riveting, threading or bonding. In addition, the first connecting member 131 and the metal part 111 can also be an integrally formed structure, and / or the second connecting member 132 and the support member 12 can be an integrally formed structure.

[0048] It should be further explained that the metal part 111 is provided with a mounting portion for mounting the rotating connection structure 13, the mounting portion includes a first mounting portion 1112 and a second mounting portion 1113, the first connecting member 131 is mounted on the first mounting portion 1112, the first pivot portion 1311, the second pivot portion 1321 and the rotating shaft are mounted on the second mounting portion 1113, and the second connecting member 132 is placed outside the mounting portion for connecting the support member 12.

[0049] Please refer to the attached Figure 6In some optional embodiments, the shell 30 includes a receiving portion 31, and the base 11 is installed in the receiving portion 31 and can rotate in the receiving portion 31. Specifically, the shell 30 includes a back plate, one side of the back plate is provided with a mounting portion for installing electronic products, and the other side of the back plate is provided with a receiving portion 31 for installing the base 11. In a specific example, the base 11 is a circular ring structure, the receiving portion 31 is a circular ring groove adapted thereto, the base 11 is rotatable relative to the center of the receiving portion 31, and the edge of the base 11 and the edge of the receiving portion 31 can be connected in a snap-fit ​​manner. In this embodiment, the flexibility of the bracket protective shell is increased by arranging the base 11 to be rotatable relative to the center of the receiving portion 31, so that the user can more flexibly adjust the angle and orientation of the support body. It should be further pointed out that in order to ensure that the base 11 can rotate smoothly relative to the center of the accommodating portion 31 and maintain a stable connection during the rotation process, the material of the non-metallic part 112 should be selected with appropriate hardness. The reason is that materials with too low hardness are prone to deformation or distortion during rotation, causing the connection between the base 11 and the accommodating portion 31 to become unstable, thereby affecting the reliability and stability of the entire bracket protective shell. In addition, materials with too low hardness will increase the friction between the base 11 and the accommodating portion 31, making the rotation unsmooth and may even cause jamming or jamming, affecting the user's experience.

[0050] In some optional embodiments, the housing 30 further includes a receiving portion 32 communicating with the receiving portion 31 and an opening 33 provided at the communication point between the receiving portion 31 and the receiving portion 32. When the support member 12 is in the receiving state, the support member 12 is located in the receiving portion 32, and the rotating connection structure 13 is located in the opening 33. It should be further explained that the support body has a supporting state and a receiving state relative to the housing 30. In the receiving state, the support body is placed in the receiving portion 32, and the rotating connection structure is placed in the opening 33 between the receiving portion 31 and the receiving portion 32. When the support body is in the receiving state, the electronic product can be wirelessly charged with an external wireless charging device; when the bracket assembly 10 on the bracket protective shell needs to be used, the support body is rotated to be taken out of the receiving portion 32 and rotated to a preset use angle.

[0051] In some optional embodiments, the support member 12 is a support ring, and the housing 30 is provided with an avoidance hole 34 at a position corresponding to the camera of the electronic product, and a storage portion 32 is provided around the periphery of the avoidance hole 34. The position and shape of the avoidance hole 34 can be set according to the camera on the electronic product. For example, if it is suitable for a Huawei mobile phone, the avoidance hole 34 may be in the shape of a circular ring and is provided in the upper middle position of the back plate of the housing 30, the storage portion 32 surrounds the outside of the avoidance hole 34, and the accommodation portion 31 may be provided directly below the storage portion 32 at a position corresponding to the wireless coil inside the mobile phone. When the base 11 of the annular structure is mounted on the accommodation portion 31, the hollow portion of the base 11 of the annular structure is the wireless charging area 20.

The placement space 115 can be a groove arranged on the base 11, and the magnetic component 14 is embedded in the groove. The magnetic component 14 is an adsorbent element such as a magnet. Specifically, the magnetic component 14 may include a plurality of magnets, and the plurality of magnets are arranged in the groove.
