Battery, telescoping device, shell, and battery fixing system

[0042] refer to Figure 7 , which shows a schematic structural diagram of Embodiment 2 of a telescopic device applied to an electronic device housing according to the present invention, wherein the telescopic device C may specifically include: a telescopic component 701 and a shrapnel 702;

[0043] Wherein, the telescopic component 701 is provided with a first notch 7011 and a second notch 7012;

[0044] The elastic piece 702 can be used to fit into the first notch 7011 or the second notch 7012 through elastic deformation in the vertical direction, so as to realize the extension and contraction of the telescopic component 701 .

[0045] In a specific embodiment, the first notch 7011 and the second notch 7012 may be located on the side of the telescopic member 701 adjacent to the elastic piece 702; the shape, size and other characteristics of the first notch and the second notch may be consistent with the shape of the top end of the elastic piece, The size is adapted to facilitat

[0055] The present invention also provides Embodiment 1 of a battery fixing system, which may specifically include: the aforementioned battery, the aforementioned retractable device applied to the casing of the electronic equipment, and the aforementioned casing of the electronic equipment; The opposite side of the sheet is provided with at least one groove, which is convenient for placing the telescopic device. In the embodiment of the present invention, one groove is used as an example. Specifically, the telescopic device may include a telescopic part, and the telescopic part is used to extend into the groove of the battery to realize the fixing of the battery, and to shrink into the space of the casing to realize the removal of the battery.

[0056] Example 2 of the battery fixing system

[0057] refer to Figure 8 and Figure 9 , which respectively show a second embodiment of a battery fixing system of the present invention and a cross-sectional view of the second embodimen
