Description

Technical Field

[0001] The utility model relates to the technical field of batteries, and in particular to a battery pack self-locking mechanism and a battery pack. Background Art

[0002] A battery pack is a drawer-type battery module, which is usually used for storage and power supply in the battery compartment of an energy storage system or electric vehicle. It can be inserted or removed independently, similar to the design of a drawer. The battery pack has a hot-swappable function, which allows the battery pack to be pulled out for repair and replacement while it is working. However, when repairing and replacing the battery pack, the battery pack module is prone to slipping out. The battery pack module is relatively heavy, and it also poses a great threat to personal safety when it slips out. Therefore, it is necessary to set a locking structure to prevent the battery pack module from slipping out during the process of pushing or pulling out the battery pack module.

[0003] At present, traditional drawer-type battery modules generally use rubber clamps to clamp limit blocks to prevent the modules from sliding out. For the traditional drawer-type module locking method, since the rubber clamps are easily affected by time and temperature, the clamping force will gradually decrease, which reduces the effect of the clamping force. Especially for heavier modules such as battery packs, the risk of sliding out is greatly increased, which can easily cause safety hazards. Utility Model Content

[0004] The utility model aims to solve the problem that the rubber clamp in the prior art is easily affected by time and temperature and the clamping force effect is easily reduced, and proposes a battery pack self-locking mechanism and a battery pack.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A battery pack self-locking mechanism comprises a locking plate with an L-shaped structure, wherein a turning point is arranged at the turning corner of the locking plate; and a limiting inclined plate matched with the locking plate, wherein one end of the locking plate matches with the limiting inclined plate, and when the limiting inclined plate moves, the locking plate rotates around the turning point and abuts against the outer wall of the limiting inclined plate, and a reset assembly is arranged on the locking plate.

[0007] In order to facilitate resetting of the locking plate so that the locking plate can improve the limiting effect, preferably, the resetting component includes a limiting spring.

[0008] In order to facilitate the installation of the limit spring, a storage bin is further included, and both ends of the limit spring are fixedly connected to the storage bin and the locking plate respectively.

[0009] In order to facilitate the connection of the locking plate, further, a first connecting plate is fixedly connected to the storage bin, the locking plate is rotatably connected to the first connecting plate, and the turning point is arranged on the first connecting plate.

[0010] In order to facilitate the adjustment of the position of the locking plate, preferably, a second connecting plate is fixedly connected to the storage bin, a clamping plate is rotatably connected to the second connecting plate, a limiting groove is provided on the locking plate, one end of the clamping plate extends into the limiting groove, and an adjusting bolt is provided on the storage bin, and the end of the adjusting bolt cooperates with the other end of the clamping plate.

[0011] A battery pack also includes a battery module, and the limiting inclined plate is fixedly connected to the side wall of the battery module.

[0012] Compared with the prior art, the utility model provides a battery pack self-locking mechanism and a battery pack, which have the following beneficial effects:

[0013] 1. The self-locking mechanism of the battery pack can ensure that the battery module is firmly fixed in the storage bin through the cooperation of the locking plate and the limiting inclined plate, so as to avoid falling during transportation or use, thereby improving the safety of use. Compared with the locking method of the traditional drawer-type module, it will not be affected by time and temperature. While ensuring the clamping strength, it can also reduce the risk of the battery module sliding out, so as to improve the user experience. Users do not have to worry about safety problems caused by the battery module falling, and it is more convenient and assured to use.

[0014] 2. The self-locking mechanism of the battery pack can be adjusted by adjusting the position of the bolt to unlock the self-locking mechanism, so that the battery module can be conveniently taken out of the storage compartment, thereby achieving the effect of being able to unlock when self-locking, which can improve the user experience;

[0015] 3. The battery pack can be removed or installed in the storage compartment as needed, which can improve the user experience.

[0016] The parts not involved in the device are the same as the existing technology or can be implemented by the existing technology. The utility model can ensure that the battery module is firmly fixed in the storage bin to avoid falling during transportation or use, thereby improving the safety of use. Compared with the traditional drawer-type module locking method, it will not be affected by time and temperature. While ensuring the clamping force, it can also reduce the risk of the battery module slipping out, so as to improve the user experience. Users do not have to worry about safety problems caused by the battery module falling, and it is more convenient and reliable to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Also, please refer to Figure 3 As shown in the figure, a limiting spring 401 is also fixedly connected to the inner wall of the storage bin 3, and the other end of the limiting spring 401 is fixedly connected to the outer wall of the locking plate 4, so that it can limit the locking plate 4. Here, when the battery module 1 needs to be limited, the battery module 1 can be pushed into the storage bin 3.

[0029] The working principle is as follows: the limit spring 401 can continuously limit the position of the locking plate 4, and the limit inclined plate 2 will contact the end of the locking plate 4 during the movement, and the limit spring 401 can be compressed during the displacement, and then the limit inclined plate 2 will cooperate with the locking plate 4 to self-lock the battery module 1 in the storage bin 3, thereby ensuring that the battery module 1 is firmly fixed in the storage bin 3 to avoid falling during transportation or use, thereby improving the safety of use.
