[0029] The connection method can adopt existing methods such as bonding, welding, bolt connection, etc., depending on actual needs.

[0030] Please refer to Figures 1 to 4As shown in the figure, this embodiment includes a battery cover body 1, a fixing component 2, and a limiting component 3. Among them, the battery cover body 1 includes a substrate body 101 and an electrode plate body 102. Two electrode plate bodies 102 are symmetrically arranged on one side of the substrate body 101 through bolts. The fixing component 2 is arranged inside the electrode plate body 102. Among them, the fixing component 2 includes a through-hole groove 201, a receiving groove 202, and an internal-thread sleeve 203. A through-hole groove 201 is opened on the electrode plate body 102. A receiving groove 202 is opened inside the through-hole groove 201. The internal-thread sleeve 203 is connected to the inner wall of the receiving groove 202 through the limiting component 3.

[0031] In this utility model, through the provided through-hole groove 201, receiving groove 202, and internal-thread sleeve 203, when multiple batteries need to be combined together, first, fix multiple batteries on a sheet. Subsequently, align the holes on the sheet with the through-hole groove 201, use a screw to pass through the holes on the sheet and the through-hole groove 201, and rotate the screw so that the screw is threadedly connected to the internal-thread sleeve 203 through the limiting component 3. Through the threaded connection method, not only can the positions of multiple batteries be fixed and connected together, but also it is convenient to replace a single battery that is damaged or has an adverse reaction, greatly improving the battery replacement efficiency.

[0032] As a preferred implementation, the electrode plate body 102 is made of aluminum material, and the electrode plate body 102 is integrally formed by stamping. The processing method of integral stamping can make the aluminum electrode plate body 102 softer itself, so as to facilitate inserting the internal-thread sleeve 203 into the receiving groove 202, greatly improving the convenience of assembling the internal-thread sleeve 203.

[0033] As a preferred implementation, the electrode plate body 102 has a T-shaped structure, and the T-shaped surface of the electrode plate body 102 is arranged in the direction close to the substrate body 101. To facilitate keeping the position of the sheet connected to multiple batteries away from the substrate body 101.

[0034] As a preferred implementation, the fixing component 2 further includes a gasket groove 204 and a gasket 205. A gasket groove 204 is opened on the side of the receiving groove 202 close to the substrate body 101. The gasket 205 is arranged in the gasket groove 204, and the gasket 205 is in contact with the substrate body 101. In this utility model, by providing the gasket groove 204 and the gasket 205, since the substrate body 101 can be electrified, when the used screw is too long, the screw is very likely to pierce through the substrate body 101, resulting in a short circuit of the substrate body 101 and affecting the normal use of the battery cover body 1 and the battery, thus playing a protective effect on the battery.

[0035] As a preferred embodiment, the internal thread sleeve 203 and the gasket 205 are both made of stainless steel. Making the internal thread sleeve 203 and the gasket 205 of stainless steel can not only endow the internal thread sleeve 203 and the gasket 205 with non-conductive properties, but also improve the self-strength of the internal thread sleeve 203 and the gasket 205, thereby enhancing the durability of the internal thread sleeve 203 and the gasket 205.

[0036] As a preferred embodiment, the limiting component 3 includes a rotation stopping groove 301 and a rotation stopping tooth 302; a plurality of rotation stopping grooves 301 are annularly and arrayedly formed on the side of the receiving groove 202 away from the inner wall of the substrate body 101; the rotation stopping tooth 302 is arranged in the receiving groove 202, and the end of the rotation stopping tooth 302 passes through the receiving groove 202 and is fixedly connected to the internal thread sleeve 203; wherein, the rotation stopping tooth 302 has an arc-shaped structure, and the cross-section of the rotation stopping tooth 302 is an isosceles trapezoid structure, and the dimension of the rotation stopping tooth 302 on the side close to the internal thread sleeve 203 is larger than the dimension of the rotation stopping tooth 302 on the side away from the internal thread sleeve 203. By providing the rotation stopping groove 301 and the rotation stopping tooth 302 in the present utility model, when the screw rotates during the threaded connection with the internal thread sleeve 203, the rotation of the internal thread sleeve 203 in the receiving groove 202 can be avoided, thereby playing a limiting role on the internal thread sleeve 203. By setting the rotation stopping tooth 302 into an arc-shaped structure, the arc surface of the rotation stopping tooth 302 will not affect the stability of the threaded connection between the screw and the internal thread sleeve 203. By setting the cross-section of the rotation stopping tooth 302 into an isosceles trapezoid structure, when the screw is threaded from top to bottom in the internal thread sleeve 203, the upward movement of the screw will become tighter and tighter, greatly improving the stability of the internal thread sleeve 203 in the receiving groove 202.

[0037] Working principle

[0038] For this battery cover plate that is convenient for disassembly and assembly, when a plurality of batteries need to be combined together, first, fix the plurality of batteries on the sheet board. Subsequently, align the holes on the sheet board with the through-hole grooves 201, use screws to pass through the holes on the sheet board and the through-hole grooves 201, and rotate the screws to make the screws threadedly connected with the internal thread sleeve 203. Since the position of the rotation stopping tooth 302 in the rotation stopping groove 301 is fixed, when the screw is threadedly connected with the internal thread sleeve 203, the internal thread sleeve 203 will not rotate in the receiving groove 202, so that the position of the internal thread sleeve 203 is fixed until the screw is in contact with the gasket 205. At this time, the threaded connection between the screw and the internal thread sleeve 203 reaches the maximum limit. When disassembling the plurality of batteries and the sheet board, rotate the screw in the opposite direction to make the screw move upward, so that the screw is threadedly connected with the internal thread sleeve 203 until the screw disengages from the connection with the internal thread sleeve 203. At this time, the battery can be disassembled at will for replacement or repair.
