[0040] like Figure 1-Figure 5As shown, this embodiment provides a tab shaping assembly, which includes a cover member 1 and a shaping member 2. The cover member 1 covers the opening of the battery housing 100 and is provided with at least one first through hole 11. The first through hole 11 is configured to pass through the tab. The shaping member 2 is arranged between the battery housing 100 and the cover member 1. Corresponding to the first through hole 11, the shaping member 2 is provided with a second through hole 21. The tab can be passed through the second through hole 21 and the first through hole 11, and is folded over the end of the cover member 1 away from the battery housing 100. The shaping member 2 is provided with a shaping portion 22 on the end away from the cover member 1. The shaping portions 22 are arranged on opposite sides of the second through hole 21 to shape the tab.

[0041] In this embodiment, the cover member 1 is sealed at the opening of the battery housing 100 and is provided with at least one first through hole 11. The first through hole 11 is configured to pass through the tab. Corresponding to the first through hole 11, the shaping member 2 is provided with a second through hole 21. The tab can be passed through the second through hole 21 and the first through hole 11, and is folded at the end of the cover member 1 away from the battery housing 100, so that the tab can pass through the first through hole 11 and the second through hole 21 to the outside of the battery housing 100, thereby preventing the tab from occupying space inside the battery and improving the internal space utilization of the battery housing 100. The shaping member 2 is provided between the battery housing 100 and the cover member 1 to ensure that the tab is shaped before passing through the first through hole 11, further saving space inside the battery. The shaping member 2 is provided with a shaping portion 22 at one end facing away from the cover member 1. The shaping portions 22 are arranged on opposite sides of the second through hole 21. When the tab passes through the second through hole 21, the tab is shaped by the shaping portions 22 on both sides of the second through hole 21. This not only improves the shape of the tab, but also simplifies the shaping process, improves the convenience and safety of the shaping, and reduces the risk of short circuits. Through the above arrangement, the tab shaping assembly of this embodiment can improve the space utilization inside the battery, facilitate the shaping of the tab, and improve the safety of use.

[0042] The specific structure of the tab shaping component is described below:

[0043] Specifically, if Figure 2 As shown, the tab shaping assembly further includes an insulating member 3 , which is disposed between the tab and the wall of the first through hole 11 to ensure insulation between the tab and the cover member 1 and avoid direct contact between the tab and the cover member 1 to cause a short circuit.

[0044] More specifically, the insulating member 3 is made of plastic or rubber, which can effectively isolate the current and prevent electrical faults such as short circuits. The specific material of the insulating member 3 is not limited here.

[0045] More specifically, in this embodiment, the cover member 1, shaping member 2, and insulating member 3 all have plate-like structures to ensure that the tab shaping assembly has a laminated plate structure, making the overall structure more compact, thereby saving internal battery space and improving internal battery space utilization. In other embodiments, the above 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.

[0046] Specifically, if Figure 2 As shown, the insulating member 3 is provided with a receiving groove 31, which is configured to place the connecting piece or the pole, thereby providing a stable and precise installation position for the connecting piece or the pole, which facilitates the installation operation. The insulating member 3 is provided with a third through hole 32 corresponding to the first through hole 11. The tab can pass through the second through hole 21, the first through hole 11 and the third through hole 32 and be connected to the connecting piece or the pole, thereby ensuring the continuity and smoothness of the tab's path. Moreover, since the third through hole 32 is provided on the insulating member 3, when the tab passes through the third through hole 32, it can ensure effective isolation between the tab and the insulating member 3, thereby maintaining the insulation performance of the overall structure and avoiding the danger of short circuit.

[0047] More specifically, if Figure 2 As shown, there is at least one accommodating slot 31, the specific number of which is adjusted based on the number of connecting tabs and terminals, thereby adapting to the requirements of batteries of different specifications and configurations, thereby improving the versatility and flexibility of the tab shaping assembly. Corresponding to each accommodating slot 31, the insulating member 3 is provided with two third through holes 32, which are located on opposite sides of the accommodating slot 31. The two tabs can be respectively inserted into the two third through holes 32, which not only prevents interference between the two tabs, but also reduces bending and folding of the tabs, thereby reducing resistance loss and improving current transmission efficiency.

[0048] It should be noted that if only the positive electrode or the negative electrode is designed on the cover member 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 and the negative electrode is set on the other side of the cover member 1, 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 member 1, which can improve the utilization rate of the internal space of the battery.

[0049] Specifically, if Figure 2-Figure 5As shown, the cover member 1 is provided with an explosion-proof valve 12. When the internal pressure of the battery rises abnormally, the explosion-proof valve 12 can automatically open to release the pressure inside the battery, preventing 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, the outside of the cover, or not provided. The shaping member 2 is provided with an air vent 23 arranged opposite to the explosion-proof valve 12. By providing the air vent 23, 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. The specific structure and working principle of the explosion-proof valve 12 are clear to those skilled in the art, and will not be described in detail here.

[0050] More specifically, if Figure 3-Figure 5 As shown, there are multiple air holes 23, which are arranged in a matrix and spaced apart on the shaping member 2, so that the air holes 23 can be evenly distributed on the surface of the shaping member 2, thereby ensuring the uniformity and effectiveness of air circulation and reducing safety risks caused by excessive temperature.

[0051] Specifically, if Figure 3-Figure 5 As shown, the shaping member 2 includes a plastic member 24. The plastic member 24 of this embodiment is made of plastic, which has the advantages of being lightweight, corrosion-resistant, and easy to process. It can protect and isolate the tab and the cover member 1. The plastic member 24 in other embodiments can be made of a silicone plate. The specific material and structure of the plastic member 24 are not limited here, as long as it can achieve the above-mentioned functions. Figure 3 As shown, the shaping portion 22 includes a plurality of shaping plates 221 disposed obliquely on the plastic part 24. The shaping plates 221 extend at an angle to the plastic part 24. The shaping plates 221 directly contact the tabs to apply pressure or thrust, thereby changing the shape and size of the tabs. The oblique shaping plates 221 enable precise shaping of the tabs at various angles and directions.

[0052] More specifically, if Figure 3-Figure 5 As shown, one second through hole 21 corresponds to two shaping plates 221, and the two shaping plates 221 are respectively arranged on both sides of a second through hole 21 and tend to be arranged in opposite directions. When the tab is passed through the second through hole 21, the shaping plates 221 on both sides of the second through hole 21 can exert precise control force on the tab from two opposite directions, ensuring that the tab is adjusted to a predetermined shape and position, and improving the space utilization inside the battery, avoiding problems such as short circuit caused by morphological differences after the tab is folded.

[0053] It should be noted that, in this embodiment, the shaping member 2 is made of plastic or resin. The above materials are not only light in texture but also can play a role of insulation protection. The specific material of the shaping member 2 is not limited too much here.

[0054] This embodiment also provides a battery, comprising a battery housing 100 and a tab shaping assembly of this embodiment. The tab shaping assembly is covered at the opening of the battery housing 100. The tab shaping assembly is provided with a liquid injection hole 13. The interior of the battery housing 100 is connected to the outside through the liquid injection hole 13, which can improve the space utilization inside the battery, facilitate the shaping of the tabs, and improve the safety of use. It is understood that the liquid injection hole can be provided or not. If provided, it can be provided near the positive electrode side, near the negative electrode side, or between the positive and negative electrodes.

[0055] This embodiment also provides a battery pack, which includes the battery of this embodiment, can improve the space utilization inside the battery, facilitate the shaping of the tabs, and improve the safety of use.

[0056] This embodiment also provides an electrical device, comprising a power-consuming mechanism and a battery according to this embodiment, the battery being used to power the power-consuming mechanism. Alternatively, the power-consuming mechanism and a battery pack according to this embodiment are used to power the power-consuming mechanism, thereby improving space utilization within the battery, facilitating tab shaping, and enhancing safety. The power-consuming mechanism includes, but is not limited to, electric motors, electronic devices, lighting equipment, and vehicles.

[0057] 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.
