[0042] like Figures 1-6As shown, this embodiment provides a cover plate connection assembly, which includes a cover member 1, a first insulating member 2, and a second insulating member 3. The cover member 1 is provided with at least one first through hole 11, and the first through hole 11 is configured to pass through a tab. The first insulating member 2 is provided on the cover member 1 and is provided with a second through hole 21 corresponding to the first through hole 11. The second insulating member 3 is provided with a third through hole 31 corresponding to the first through hole 11. The tab can be passed through the third through hole 31, the first through hole 11, and the second through hole 21 and folded over the first insulating member 2. One of the first insulating member 2 and the second insulating member 3 is provided with a connecting protrusion 32, and the other is provided with a connecting groove 22. By connecting the connecting protrusion 32 to the connecting groove 22, the cover member 1 can be clamped between the first insulating member 2 and the second insulating member 3.
[0043] In this embodiment, the cover member 1 is provided with at least one first through-hole 11, which is configured to pass through a tab. The first insulating member 2 is provided on the cover member 1 and has a second through-hole 21 corresponding to the first through-hole 11. The second insulating member 3 has a third through-hole 31 corresponding to the first through-hole 11. The tab can be passed through the third through-hole 31, the first through-hole 11, and the second through-hole 21 and folded over the first insulating member 2, so that the tab can pass through the first through-hole 11, the second through-hole 21, and the third through-hole 31 to the outside of the battery, thereby preventing the tab from occupying space inside the battery and improving the space utilization inside the battery casing 100. One of the first insulating member 2 and the second insulating member 3 is provided with a connecting protrusion 32, and the other is provided with a connecting groove 22. By connecting the connecting protrusion 32 to the connecting groove 22, the cover member 1 can be sandwiched between the first insulating member 2 and the second insulating member 3, and then the first insulating member 2, the cover member 1, and the second insulating member 3 are assembled into an integral structure, which not only improves the connection strength of the overall structure but also facilitates assembly. Through the above arrangement, the cover plate connection assembly of this embodiment can improve the space utilization inside the battery and is easy to assemble.
[0044] The specific structure of the cover plate connection assembly is described below:
[0045] Specifically, if Figure 3 As shown, in this embodiment, the connecting protrusion 32 is provided on the second insulating member 3, and the connecting groove 22 is provided on the first insulating member 2. When the first insulating member 2 and the second insulating member 3 are respectively brought together toward the cover member 1 from opposite sides of the cover member 1 for assembly, the connecting protrusion 32 passes through the first through-hole 11 in the cover member 1 and extends into the connecting groove 22, thereby achieving the overall assembly of the first insulating member 2, the cover member 1, and the second insulating member 3, making the operation more convenient and quick. In other embodiments, the connecting protrusion 32 may be provided on the first insulating member 2, and the connecting groove 22 may be provided on the second insulating member 3. As long as the above-mentioned functions can be achieved, the specific positions of the above-mentioned components are not limited here.
[0046] More specifically, if Figure 2-Figure 5 As shown, in this embodiment, the connecting protrusion 32 is provided at the open end of the third through hole 31, so that when the tab passes through the third through hole 31, the connecting protrusion 32 will not hinder it, thereby ensuring the smooth passage of the tab. The connecting groove 22 is provided on the inner wall of the second through hole 21, without occupying additional space. The connecting protrusion 32 can pass through the first through hole 11 and extend into the connecting groove 22, which not only simplifies the assembly process, but also ensures the accuracy and stability of the connection of the above components. By aligning the first through hole 11, the second through hole 21 and the third through hole 31, and inserting the connecting protrusion 32 into the connecting groove 22, the first insulating member 2, the cover member 1 and the second insulating member 3 can be tightly connected, thereby improving the assembly efficiency.
[0047] Specifically, if Figure 3-Figure 5 As shown, a fixing portion 321 is provided at one end of the connecting protrusion 32 extending into the connecting groove 22, and the fixing portion 321 abuts against the end of the connecting groove 22 facing away from the cover member 1, so that the connection between the connecting protrusion 32 and the connecting groove 22 is more reliable, preventing the connecting protrusion 32 from being pulled out of the connecting groove 22.
[0048] More specifically, in this embodiment, when the connecting protrusion 32 extends into the connecting groove 22, the end of the connecting protrusion 32 is heat-soldered or heat-riveted to form the fixing portion 321. Compared to traditional bonding or mechanical fastening methods, heat-soldered or heat-riveted connections are faster and simpler. Assemblers simply insert the connecting protrusion 32 into the connecting groove 22 and then use heat-soldered or heat-riveted equipment to complete the connection. This not only improves assembly efficiency but also enhances the stability of the connection between the connecting protrusion 32 and the connecting groove 22.
[0049] More specifically, if Figure 2-Figure 5 As shown, the connection groove 22 is provided with two protrusions 221. The two protrusions 221 are arranged facing each other and spaced apart, forming a step-like structure. The fixing portion 321 abuts against the two protrusions 221, thereby forming a multi-point support structure. This support method is more stable than single-point support and can withstand greater forces and torques, thereby enhancing the connection strength between the connection protrusion 32 and the connection groove 22.
[0050] Specifically, if Figure 2-Figure 6As shown, a shaping portion 33 is provided at one end of the second insulating member 3 facing away from the cover member 1. The shaping portion 33 is provided on opposite sides of the third through hole 31 and is used to shape the tab, so that when the tab passes through the third through hole 31, the tab is shaped by the shaping portions 33 on both sides of the third through hole 31. This not only improves the shape of the tab, but also simplifies the shaping process, improves the convenience and safety of shaping, and reduces the risk of short circuits. Among them, the shaping portion 33 includes but is not limited to a pressure plate, a slider and a blowing assembly, and the tab is shaped by moving the pressure plate or slider, or by blowing air toward the tab through the blowing assembly to smooth the surface of the tab. It is understandable that those skilled in the art are aware of the specific structure and working principle of the pressure plate, slider and blowing assembly, and will not be repeated here. Moreover, there is no limitation on the specific structure of the shaping portion 33, as long as it can achieve the above-mentioned functional effects.
[0051] Specifically, if Figure 3 and Figure 6 As shown, the second insulating member 3 includes a plastic member 34, which can protect and isolate the tabs and the cover member 1. The shaping portion 33 includes a plurality of shaping plates 331 obliquely arranged on the plastic member 34. The extension direction of the shaping plates 331 is set at an angle to the extension direction of the plastic member 34. The shaping plates 331 directly contact the tabs to apply pressure or thrust, thereby changing the shape and size of the tabs. The obliquely arranged shaping plates 331 can accurately shape the tabs at different angles and directions. Among them, the plastic member 34 of this embodiment is a plastic plate, which has the advantages of being lightweight, corrosion-resistant, and easy to process. The plastic member 34 in other embodiments can also be made of a silicone plate, which is not limited here.
[0052] More specifically, if Figure 6 As shown, one third through hole 31 corresponds to two shaping plates 331, and the two shaping plates 331 are respectively arranged on both sides of one third through hole 31 and tend to be arranged in opposite directions. When the tab is passed through the third through hole 31, the shaping plates 331 on both sides of the third through hole 31 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] Specifically, the cover member 1 is provided with an explosion-proof valve. When the internal pressure of the battery rises abnormally, the explosion-proof valve 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 can be facing the inside of the cover, the outside of the cover, or not provided. The plastic part 34 is provided with a vent hole arranged opposite to the explosion-proof valve. By providing the vent hole, air circulation can be increased, which helps the battery to better dissipate heat and reduce the safety risks caused by excessive temperature. The specific structure and working principle of the explosion-proof valve are clear to those skilled in the art and will not be described in detail here.
[0054] It should be noted that in this embodiment, the first insulating member 2 and the second insulating member 3 are both made of plastic. In other embodiments, the first insulating member 2 and the second insulating member 3 may also be made of rubber. Both plastic and rubber can effectively isolate current and prevent electrical faults such as short circuits. The specific materials of these components are not particularly limited herein.
[0055] This embodiment further provides a battery, which includes a battery housing 100 and a cover plate connecting assembly of this embodiment. The cover member 1 is disposed at the opening of the battery housing 100 , which can improve the space utilization inside the battery and facilitate assembly.
[0056] This embodiment also provides a battery pack, which includes the battery of this embodiment, can improve the space utilization inside the battery and is easy to assemble.
[0057] This embodiment also provides an electrical device, comprising a power-consuming mechanism and the battery of this embodiment, the battery being used to power the power-consuming mechanism. Alternatively, the power-consuming mechanism and the battery pack of this embodiment are used to power the power-consuming mechanism, thereby improving internal battery space utilization and facilitating assembly. The power-consuming mechanism includes, but is not limited to, electric motors, electronic devices, lighting equipment, and vehicles.
[0058] 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.
