[0024] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0025] Please refer to Figures 1 to 3 The utility model provides a battery structure, including: a battery body 1, the battery body 1 has a pole ear 11, a part of the pole ear 11 is exposed and arranged outside the battery body 1, and the pole ear 11 is electrically connected to the electrode sheet of the battery body 1; a battery bracket 2, the battery bracket 2 is arranged on the battery body 1, and the battery bracket 2 fixes the pole ear 11; when the battery structure is installed on the electronic device body 10, the pole ear 11 is electrically connected to the power input terminal 102 of the electronic device body 10, and the power input terminal 102 is electrically connected to the battery protection board inside the electronic device body 10, so as to control the charge and discharge of the battery body 1 through the battery protection board.

[0026] The battery structure adopting this structural design allows the pole ear 11 of the battery body 1 to extend to the outside of the battery body 1 and be fixed by the battery bracket 2. When the battery structure is installed on the electronic device body 10, the exposed pole ear is electrically connected to the power input terminal 102 of the electronic device body 10, wherein the power input terminal 102 is electrically connected to the battery protection board in the electronic device body 10. In other words, the battery protection board is no longer provided in the battery structure, and the pole ear 11 of the battery body is exposed and provided as a wiring terminal. As long as the electronic device body 10 in which it is installed is provided with a battery protection board, the battery protection board can be avoided from occupying the internal space of the battery, thereby freeing up more energy storage space inside the battery structure, reserving a larger space for the battery to place the battery cells, thereby increasing the battery capacity and improving the battery life of the electronic device. The battery structure of this embodiment can solve the technical problem in the related art that the battery capacity of the electronic device is difficult to increase, resulting in poor battery life of the electronic device.

[0027] Among them, the above-mentioned battery protection board is an integrated circuit board that performs charge and discharge protection on the battery body, and can achieve at least one of the following protections: overcharge protection, over-discharge protection, overcurrent protection, short circuit protection, and ultra-high temperature charge and discharge protection.

[0028] As described above, a portion of the tab 11 is exposed and arranged outside the battery body 1, so as to be connected to the power input terminal 102 of the electronic device body 10 to realize power supply. In a preferred embodiment, a portion of the tab 11 is inserted into the battery holder 2, and the length of the portion of the tab 11 protruding from the battery holder 2 is greater than or equal to 3 mm. By inserting the tab 11 into the battery holder 2, the tab 11 can be reliably fixed, thereby ensuring position stability, and further ensuring the reliability of its cooperation with the power input terminal 102. By designing the length of the portion of the tab exposed to the outside to be greater than or equal to 3 mm, sufficient contact area can be provided to contact the power input terminal 102, ensuring the reliability of the electrical connection between the two, thereby realizing reliable power supply to the electronic device body 10.

[0029] In specific implementation, the battery bracket 2 can be arranged in different ways:

[0030] For example, in an optional setting mode, the battery holder 2 has a tab avoidance hole, and the tab 11 is inserted into the tab avoidance hole, so that the tab 11 is limited and fixed by the inner wall of the tab avoidance hole. That is to say, in this embodiment, the battery holder 2 and the battery body 1 are assembled together after being manufactured, and the tab avoidance hole is reserved in the battery holder 2 during manufacturing, so that the tab 11 can be inserted therein. The use of this structural design is conducive to the assembly production of the battery structure, thereby improving the production efficiency, and is conducive to the subsequent battery disassembly and maintenance.

[0031] For another example, in another optional setting mode, the battery holder 2 is formed on the battery body 1 by injection molding. In this embodiment, the battery holder 2 is formed by directly injection molding on the battery body 1, and the implementation method is more concise and flexible, which is conducive to reducing the manufacturing cost of the battery structure, and the injection molding structure has a better fixing effect on the tab 11.

[0032] In a specific embodiment, the gap between the inner wall of the tab avoidance hole and the outer surface of the tab 11 ranges from 0.05 mm to 0.1 mm. By designing the gap between the inner wall of the tab avoidance hole and the outer surface of the tab 11 to be 0.05 mm to 0.1 mm, it can be ensured that the tab 11 is smoothly inserted into the tab avoidance hole, and the tab avoidance hole will not be too large, so that the tab 11 can have a reliable limiting and fixing effect.

[0033] Furthermore, the battery body 1 is a plate-like structure, and the battery body 1 has a first plate surface and a second plate surface. When the battery body 1 is installed on the electronic device body 10, the first plate surface faces the electronic device body 10, and the second plate surface faces away from the electronic device body 10; the portion of the tab 11 exposed outside the battery body 1 is bent to the first plate surface, and the battery structure also includes a protective layer 4, which is located between the tab 11 and the main part of the battery body 1.

[0034] By designing a protective layer between the tab 11 and the main part of the battery body 1, the tab 11 or the corresponding power input terminal 102 can be prevented from puncturing the battery cell of the battery body 1, which can effectively improve the safety of the battery structure. In actual implementation, the material and shape of the protective layer 4 can be flexibly selected according to actual needs, as long as it can prevent the battery cell from being punctured.

[0035] In an optional embodiment, the battery holder 2 has a first matching portion 21; the battery structure further includes: a fixing frame 3, the fixing frame 3 has a fixing portion 31 for connecting with the electronic device body 10, and the fixing frame 3 also has a second matching portion 32, at least part of the shape of the second matching portion 32 matches at least part of the shape of the first matching portion 21, when the fixing frame 3 is fixed to the electronic device body 10, the second matching portion 32 matches the first matching portion 21, so that the battery holder 2 and the battery body 1 are fixed to the electronic device body 10 through the fixing frame 3. In this embodiment, the first matching portion 21 is designed on the battery holder 2, and the fixing frame 3 is designed. When the battery body 1 and the battery holder 2 are placed in the electronic device body 10 together, the second matching portion 32 of the fixing frame 3 can be matched with the first matching portion 21 of the battery holder 2, and the fixing frame 3 is connected to the electronic device body 10 through the fixing portion 31. In this way, the battery holder 2 can be limited by the fixing frame 3, so that the battery body 1 is stably fixed in the electronic device body 10. Compared with the method of fixing the battery by gluing in the related art, the use of this snap-fitting battery fixing method can more conveniently realize the removal and replacement of the battery, thereby solving the technical problem of the difficulty in removing and replacing the battery of the electronic device in the related art.

[0036] In a preferred embodiment, the battery structure further includes an insulating protective layer 5 , which wraps at least a portion of the battery body 1 , and at least a portion of the insulating protective layer 5 is located on the second plate surface of the battery body 1 .

[0037] As described above, on the basis of designing the protective layer 4 on the first plate surface of the battery body 1, the present embodiment further designs an insulating protective layer 5, which wraps at least a portion of the battery body 1, thereby improving the insulating protection effect of the battery, and at least a portion of the insulating protective layer 5 is located on the second plate surface of the battery body 1, so that the battery body 1 can be more effectively protected by the protective layer 4 on the first plate surface and the insulating protective layer 5 on the second plate surface. In actual implementation, a label can be printed on the insulating protective layer 5, so as to facilitate the display of relevant information of the battery structure.

[0038] Specifically, the first matching portion 21 is a depression or a protrusion disposed at the edge of the battery holder 2, and the second matching portion 32 is a protrusion or a depression disposed at the edge of the fixing frame 3; and / or, there are multiple first matching portions 21, and the multiple first matching portions 21 are arranged at intervals, and there are multiple second matching portions 32, and the multiple second matching portions 32 are arranged one-to-one with the multiple first matching portions 21. Figures 1 to 3 As shown, in this embodiment, the first matching portion 21 is a depression arranged at the edge of the battery holder 2, and correspondingly, the second matching portion 32 is a protrusion arranged at the edge of the fixing frame 3. Through the snap-fitting of the depression and the protrusion, the fixing frame 3 can limit and fix the battery holder 2. In actual implementation, the shape and size of the depression and the protrusion can be flexibly set according to actual needs, such as arc-shaped depressions or protrusions, triangular depressions or protrusions, square depressions or protrusions, etc. By designing multiple first matching portions 21 and multiple second matching portions 32, the limiting matching effect of the fixing frame 3 on the battery holder 2 can be effectively improved, which is conducive to more stable fixing of the battery structure.

[0039] In a preferred embodiment, there are multiple fixing frames 3, and the multiple fixing frames 3 are arranged in a one-to-one correspondence with the multiple edges of the battery holder 2. In actual implementation, the fixing frame 3 can be one or more. In the case where there is one fixing frame 3, it can be a strip-shaped structure and be arranged at one side edge of the battery holder 2, or it can be a shape that matches the shape of multiple side edges of the battery holder 2, so that it can cooperate with multiple side edges of the battery holder 2 at the same time, such as a closed or unclosed annular structure, a U-shaped structure, etc. As a preferred embodiment, there are multiple fixing frames 3, and the multiple fixing frames 3 are arranged in a one-to-one correspondence with the multiple edges of the battery holder 2, such as Figure 2 , Figure 3 , Figure 4 as well as Figure 5 As shown, in a specific embodiment, there are two fixing frames 3, and the two fixing frames 3 are correspondingly arranged on the opposite sides of the battery bracket 2, so as to fix the two sides of the battery bracket 2, and the battery structure can be fixed more stably while facilitating the disassembly of the battery structure.

[0040] Please refer to Figure 1 , Figure 4 and Figure 5The embodiment of the utility model also provides an electronic device, including an electronic device body 10 and the above-mentioned battery structure, the electronic device body 10 has a battery compartment 101, the battery structure is installed in the battery compartment 101, and the battery compartment 101 is provided with an electric energy input terminal 102 and a battery protection board electrically connected thereto, and the electric energy input terminal 102 is electrically connected to the pole ear 11 of the battery structure. In this embodiment, the battery structure in this embodiment does not include a battery protection board, but a battery protection board is designed in the electronic device body 10 that matches it. When the battery body 1 is installed in the electronic device body 10, the pole ear is conductively connected to the battery protection board inside the electronic device body 10. By adopting this design method, the occupation of the battery space by the battery protection board can be avoided, and a larger space can be reserved for the battery to place the battery cells, which is conducive to increasing the capacity of the battery.

[0041] In order to ensure that the tab 11 and the power input terminal 102 are always connected, the installation position of the power input terminal 102 is placed directly below the tab, that is, the positions of the two correspond to each other. At the same time, the power input terminal 102 can be designed as a spring-type structure, which is always in contact with the tab 11 through elastic force. It can also be designed as a spring-inserted structure with a lock to prevent the tab 11 from being disconnected from the power input terminal 102 when it falls, thereby ensuring the stability of the electronic device.

[0042] In a specific implementation, the battery protection board is integrated into the main board of the electronic device body 10 , or the battery protection board is a circuit board independently provided from the main board of the electronic device body 10 , and the battery protection board is electrically connected to the main board of the electronic device body 10 .

[0043] Preferably, the electronic device further comprises a cover plate 20. When the battery structure is installed in the battery compartment 101 of the electronic device body 10, the cover plate 20 can be matched with the electronic device body 10 to shield and protect the battery structure.
