[0037] like Figure 1-Figure 4 As shown, this embodiment provides a new cover plate, which includes a cover body 1, a first insulating member, a second insulating member 2, a first connecting member 3 and a clamping member 4. The cover body 1 is provided with at least one first through-hole 11, which is configured to pass through a tab. The first insulating member is arranged between the tab and the hole wall of the first through-hole 11. The second insulating member 2 is arranged on the cover body 1 and is provided with a second through-hole 21 corresponding to the first through-hole 11. The first connecting member 3 is arranged on the second insulating member 2 and is configured to be connected to the pole. The tab passes through the first through-hole 11 and the second through-hole 21 and is connected to the first connecting member 3. The clamping member 4 can clamp the second insulating member 2 and the first connecting member 3 on the cover body 1.

[0038] In this embodiment, the cover 1 is provided with at least one first through-hole 11, which is configured to receive a tab. This allows the tab to pass through the first through-hole 11 and exit to the outside, preventing the tab from occupying space within the battery and improving space utilization. A first insulating member is disposed between the tab and the wall of the first through-hole 11 to ensure insulation between the tab and the cover 1 and prevent short circuits. A second insulating member 2 is disposed on the cover 1 and defines a second through-hole 21 corresponding to the first through-hole 11. A first connector 3 is disposed on the second insulating member 2 and configured to connect to the terminal post. The tab passes through the first and second through-holes 11, 21, and connects to the first connector 3, thereby achieving an external connection between the tab and the terminal post and avoiding the problem of the terminal post being disposed within the battery and occupying internal space. A clamp 4 can clamp the second insulating member 2 and the first connector 3 to the cover 1, thereby improving the stability and safety of the overall structure, preventing the first connector 3 from moving, and facilitating assembly and enhancing ease of operation. Through the above arrangement, the new cover plate of this embodiment can improve the space utilization inside the battery and the safety of use, and is easy to assemble.

[0039] The specific structure of the new cover is described below:

[0040] Specifically, if Figure 1 and Figure 3 As shown, the cover 1 is provided with a receiving groove 13, and the second insulating member 2 is placed in the receiving groove 13, ensuring that the second insulating member 2 can be accurately placed in the predetermined position in the receiving groove 13 during the installation process to avoid positional displacement. The first through hole 11 is opened in the receiving groove 13 to ensure that the tab can be smoothly inserted into the second through hole 21 on the second insulating member 2 through the first through hole 11, avoiding misalignment between the first through hole 11 and the second through hole 21, which would affect the insertion of the tab.

[0041] Specifically, if Figure 1-Figure 4 As shown, the new cover also includes a second connector 5. The second insulating member 2 and the second connector 5 are respectively arranged on opposite sides of the cover 1. The clamping member 4 clamps the cover 1 and the second connector 5, so that the cover 1, the second insulating member 2, the first connector 3, the clamping member 4, and the second connector 5 form a stable overall structure. This not only enhances the structural strength but also helps improve the sealing performance of the new cover. Moreover, by clamping the clamping member 4 between the cover 1 and the second connector 5, the operator can more conveniently assemble the above components, improving assembly efficiency.

[0042] More specifically, in this embodiment, the cover 1, first insulating member, second insulating member 2, first connector 3, and second connector 5 all have plate-like structures, ensuring that the overall structure of the novel cover plate is a laminated plate structure. This makes the overall structure more compact, thereby saving internal battery space and improving space utilization. In other embodiments, these components may also adopt a columnar or block-like structure, as long as they can achieve the above-mentioned functions, and are not further limited here.

[0043] Specifically, if Figure 1-Figure 4 As shown, there is at least one accommodating groove 13, and two first through holes 11 are correspondingly opened in one accommodating groove 13. The two first through holes 11 are parallel to each other and spaced apart. The two ends of the clamping member 4 are respectively passed through the two first through holes 11 and clamped on the outer wall of the second connecting member 5 to ensure that the clamping member 4 can remain stable and evenly stressed when passing through the first through holes 11, thereby improving the connection strength and stability between the clamping member 4 and the first connecting member 3.

[0044] It should be noted that if only the positive electrode or the negative electrode is designed on the cover body 1, the number N of the first through holes 11 is greater than or equal to 1. If the positive electrode is set on one side of the cover body 1 and the negative electrode is set on the other side, the number N of the first through holes 11 on the positive electrode side and the negative electrode side is greater than or equal to 1. The tab passes through the first through hole 11 and is folded over the top of the cover body 1, which can improve the utilization rate of the internal space of the battery.

[0045] Specifically, if Figure 1-Figure 4 As shown, the second connector 5 is provided with a third through hole 51 corresponding to the first through hole 11. The clamping member 4 passes through the second through hole 21, the first through hole 11, and the third through hole 51, and abuts against the first connector 3, thereby ensuring that the first connector 3 is firmly connected to the cover 1, the second insulating member 2, and the second connector 5. This ensures that the first connector 3 does not shift during use and affect the normal operation of the battery, thereby improving the safety of the battery. This arrangement not only enhances the integration between the various components, but also firmly fixes the components together through the clamping force, improving the overall tightness and stability of the combined cover.

[0046] More specifically, if Figure 1-Figure 3 As shown, a slot is provided on the second insulating member 2, and the slot is used to accommodate the first connecting member 3, as shown in FIG. Figure 1-Figure 4 As shown, when the first connector 3, second insulating member 2, cover 1, and second connector 5 are stacked and assembled in sequence, the end of the U-shaped clamping member 4 passes through the second through-hole 21, first through-hole 11, and third through-hole 51 in sequence, and is engaged with the outer peripheral wall of the open end of the third through-hole 51, so that the first connector 3 abuts the bottom of the groove body, thereby assembling the above components into an integral structure, further saving space and improving the space utilization inside the battery. The clamping member 4 includes, but is not limited to, a U-shaped structure and a V-shaped structure.

[0047] More specifically, in this embodiment, corresponding to the position and number of the first through holes 11, a plurality of second through holes 21 are provided on the second insulating member 2, and a plurality of third through holes 51 are provided on the second connecting member 5. When the second insulating member 2, the cover 1, and the second connecting member 5 are stacked and assembled, the first through holes 11, the second through holes 21, and the third through holes 51 at corresponding positions face each other and connect to form a through-hole. Each first connecting member 3 is provided with two through-holes, and the two ends of the clamping member 4 are respectively provided in the two through-holes, forming a U-shaped structure, so that the first connecting member 3 can abut against the groove of the second insulating member 2 and cannot move. Through the above arrangement, the position of the first connecting member 3 is fixed, ensuring a stable connection between the tab and the pole.

[0048] Specifically, an explosion-proof valve 12 is provided on the cover body 1. When the internal pressure of the battery rises abnormally, the explosion-proof valve 12 can automatically open to release the pressure inside the battery to prevent the battery from exploding or rupturing due to overpressure. The notch on the explosion-proof valve 12 can be facing the inside of the cover body 1, or facing the outside of the cover body 1, or not provided. The second connecting member 5 is provided with a grille 52 that is arranged opposite to the explosion-proof valve 12. By providing the grille 52, air circulation can be increased, and the battery can be assisted to dissipate heat better, thereby reducing the safety risks caused by excessive temperature of the battery. Those skilled in the art are aware of the specific structure and working principle of the explosion-proof valve 12, which will not be described here.

[0049] Specifically, the first insulating member and the second insulating member 2 are both made of plastic or rubber, which can effectively isolate current and prevent electrical faults such as short circuits.

[0050] Specifically, the material of the clamping member 4 is epoxy resin or plastic. Epoxy resin and plastic, as lightweight materials, can effectively reduce the overall weight of the new cover. Moreover, epoxy resin and plastic are both excellent insulating materials that can effectively isolate current and prevent electrical faults such as short circuits.

[0051] More specifically, the thickness of the clamping member 4 is 0.1 mm to 2 mm, which ensures the strength and stability of the clamping member 4 while avoiding the increase in weight and cost caused by an excessively thick clamping member 4. Furthermore, selecting an appropriate thickness for the clamping member 4 also helps improve the space utilization within the battery, avoiding excessive battery space occupation.

[0052] This embodiment also provides a battery, comprising a housing and a novel cover of this embodiment, the novel cover being disposed over the open end of the housing. This can improve the space utilization within the battery and the safety of use. Furthermore, a liquid injection port is provided on the cover 1, through which the interior of the housing is connected to the exterior, making it easier for operators to inject electrolyte into the housing. It is understood that the liquid injection port may or may not be provided. If provided, it may be located near the positive electrode side, near the negative electrode side, or between the positive and negative electrodes.

[0053] This embodiment also provides an electrical device, comprising an electrical mechanism and the battery of this embodiment. The battery is used to power the electrical mechanism, thereby improving internal battery space utilization and safety. The electrical mechanism includes, but is not limited to, electric motors, electronic equipment, lighting equipment, and vehicles.

[0054] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
