[0057] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0058] Combine the following Figures 1 to 13 , describing an embodiment of the utility model.

[0059] According to an embodiment of the present utility model, on the one hand, a lithium battery protection board structure is provided, comprising:

[0060] A folding plate 10, wherein the folding plate 10 is bent to form at least two folding layers, and a first accommodation space 101 is formed between each two adjacent folding layers along the thickness direction, and the first accommodation space 101 is suitable for accommodating a first electronic device 100, and the first electronic device 100 is arranged on one side of any folding layer in the thickness direction;

[0061] The bracket 20 can be made of plastic material. The bracket 20 is at least partially disposed in the first receiving space 101 . Both sides of the bracket 20 in the thickness direction are respectively connected to the folding layer. The bracket 20 is suitable for encapsulating the first electronic device 100 in the first receiving space 101 .

[0062] It should be noted that the folding plate 10 can be made of FPC soft board; the folding plate 10 forms multiple folding layers through "S" shape bending, and the two adjacent folding layers can be integrally formed, or connected by wiring or soldering pins. The number of folding layers can be two layers, three layers, four layers, and more than four layers. For better explanation and understanding, the following is an example of three folding layers. The first electronic device 100 refers to an electronic component with a thickness less than or equal to the height of the first accommodating space 101. The number of first electronic devices 100 can be one or more, one type, or multiple types; the second electronic device 200 refers to an electronic component with a thickness greater than or equal to the height of the first accommodating space 101. The number of second electronic devices 200 can be one or more, one type, or multiple types.

[0063] Compared with the hard board packaging structure in the related art, the lithium battery protection board structure provided by the utility model is achieved by bending the folding board 10 to form at least two folding layers, and forming a first accommodating space 101 between each two adjacent folding layers along the thickness direction, so that the first electronic device 100 is built into the first accommodating space 101; by setting a bracket 20, and making the two sides of the bracket 20 in the thickness direction respectively connected to the two adjacent folding layers, not only can rebound or warping after bending to form the folding layer be avoided, but also the first accommodating space 101 can be completely closed, so that the first electronic device 100 is packaged in the first accommodating space 101, realizing the device being built-in, avoiding short circuit caused by exposure of the electronic device, and facilitating the process assembly of the mobile phone lithium battery.

[0064] Furthermore, the folding plate 10 is an integrally formed structure, which is beneficial for shortening the production time and increasing the overall heat dissipation area and improving the heat dissipation performance.

[0065] The hard board structure in the related art not only has the problem of exposed electronic devices, which easily leads to short circuits, but also has a long production cycle for hard board packaging. The thickness of the formed hard board packaging structure reaches 2.1mm, and the heat dissipation performance is poor.

[0066] It is worth noting that in the lithium battery protection board structure provided by the present invention, the folding board 10 is bent to form at least two folding layers, thereby performing soft board packaging. Compared with the hard board packaging in the related art, the production cycle can be shortened. The thickness of the formed soft board packaging structure is between 1.3mm and 1.6mm, which realizes the thinning of the lithium battery protection board structure. The folding board 10 with multiple folding layers is better than the hard board packaging structure in terms of heat dissipation performance.

[0071] Furthermore, in the manufacturing process, before the folding plate 10 is bent, the first electronic device 100 can be adhered to one side of the thickness direction of the first folding layer 11 by double-sided tape, and then the folding plate 10 is bent so that the first electronic device 100 is built into the first accommodating space 101, thereby realizing device integration.

[0077] It should be noted that the bending angle between the first folding layer 11 and the second folding layer 12 is α, and α satisfies 0°≤α≤180°. During the process, α can be any angle in the range of 0°≤α≤180°; the bending angle between the third folding layer 13 and the second folding layer 12 is β, and β satisfies 0°≤β≤180°.
