Referring to fig. 1 to 3, according to an embodiment of the present disclosure, a battery cover plate assembly is provided.

Specifically, the battery cover plate assembly comprises a base plate 10 and a lower plastic plate 20, wherein the lower plastic plate 20 is connected with the base plate 10 through a connecting assembly 30, the connecting assembly 30 comprises a connecting protrusion 31 and a connecting concave portion 32, one of the base plate 10 and the lower plastic plate 20 is provided with the connecting protrusion 31, and the other of the base plate 10 and the lower plastic plate 20 is provided with the connecting concave portion 32.

Use the technical scheme of this embodiment, base plate 10 passes through coupling assembling 30 with lower plastic plate 20 and is connected, wherein, coupling assembling 30 is including connecting arch 31 and connection concave part 32, be provided with connecting arch 31 through one in base plate 10 and lower plastic plate 20, another is provided with and connects concave part 32, at the in-process of battery cover plate subassembly assembly, connecting arch 31 can play location and fixed effect to lower plastic plate 20, and through connecting arch 31 and the cooperation of connecting concave part 32, can realize the firm connection of plastic plate 20 and base plate 10 down, thereby prevent that plastic plate 20 from taking place to rock in transportation and use down, the problem that the plastic easily drops under having solved prior art.

The lower plastic plate 20 is connected to the base plate 10 by interference fit through the connecting assembly 30. Therefore, the phenomenon that the plastic plate 20 can shake after being assembled can be avoided, the stability of the battery cover plate component in use is ensured, and the service life of the battery is prolonged.

The connecting members 30 are plural, and the plural connecting members 30 are arranged at intervals along the circumferential direction of the base plate 10. The arrangement further realizes the stable connection between the lower plastic plate 20 and the base plate 10, and avoids the problem that the lower plastic plate 20 can shake in the transportation and use processes.

The end of the coupling projection 31 is provided with a guide slope. The guide slope plays a guiding role in the process of assembling the lower plastic plate 20.

The connection protrusion 31 is integrally formed with the lower plastic plate 20, and the connection recess 32 is opened on the substrate 10. Wherein, the connecting protrusion 31 located in the middle of the lower plastic plate 20 can position the lower plastic plate 20 during the assembly process of the lower plastic plate 20. The coupling protrusions 31 located at both sides of the lower plastic plate 20 play a role of fixing the lower plastic plate 20 during the assembly of the lower plastic plate 20.

The connecting members 30 are plural, the connecting protrusion 31 of one connecting member 30 of the plural connecting members 30 is integrally formed with the lower plastic plate 20, and the connecting protrusion 31 of the other connecting member 30 is integrally formed with the substrate 10. This arrangement improves reliability between the plurality of connecting members 30 and the base plate 10 and the lower plastic plate 20.

The number of the connecting members 30 is four. The connecting protrusions 31 and the connecting recesses 32 are four, and each connecting protrusion 31 is in one-to-one correspondence with the connecting recess 32, so that the stable connection between the lower plastic plate 20 and the substrate 10 is ensured. In this embodiment, the number of the connecting components 30 can be increased or decreased according to actual needs. The connecting protrusion 31 may be a cylindrical protrusion or a protrusion with other shapes, as long as it can position and fix the lower plastic plate 20.

In one embodiment of the present application, the connecting recess 32 is a blind hole opened on the substrate 10 or the lower plastic plate 20. The lower plastic plate 20 is guided into the blind hole through the guide slope of the coupling protrusion 31, and then a force is applied to completely insert the coupling protrusion 31 into the blind hole, thereby fixing the lower plastic plate 20 to the battery cover plate assembly. Because all be equipped with the bonding protrusion 31 on four directions of plastic board 20 down, can prevent down plastic board 20 after the assembly and take place to rock in transportation and use, simultaneously because the size of blind hole is less than the size of bonding protrusion 31, can form interference fit in the assembling process, this will be at the peripheral great frictional force of formation of bonding protrusion 31 to plastic board 20 assembles unstable problem down has been avoided. In this embodiment, the interference fit may be formed by providing the connection protrusion 31 on the substrate 10 and the connection recess on the lower plastic plate 20.

According to another specific embodiment of the present application, a power battery is provided, and includes a battery cover plate assembly, where the battery cover plate assembly is the battery cover plate assembly in the foregoing embodiments. In this embodiment, since the power battery adopts the battery cover plate assembly in the above embodiments, the stable connection between the lower plastic plate 20 and the substrate 10 is realized, so that the effect of supporting the battery core and forming a gas generation space in the power battery by the lower plastic plate 20 is ensured, the problem of shaking the battery core of the power battery is further avoided, and the risk of tearing off the tab is reduced.
