Detailed ways

As shown in Figures 1 and 2, the battery chuck is mainly composed of five parts: an upper locking bracket 1, a lower locking bracket 2, a plastic sheath 3, a secondary locking mechanism 4, and a base 5. The clamping and loosening of the battery pile head is realized by using the interaction between metals.

When the battery chuck is pressed tightly, since two holding structures 6 are designed on the upper locking bracket 1, as the fulcrum for pressing down the upper locking bracket 1, the downward pressure moment is reduced. When the upper locking bracket 1 is pressed against the annular structure 8 on the lower locking bracket 2, the lower locking bracket 2 is forced to shrink, and then the base 5 is pressed to shrink, so as to achieve the purpose of pressing the battery pile head. Simultaneously when the upper locking bracket 1 is pressed down, its locking hole 14 just passes through the secondary locking mechanism 4 (the material of the secondary locking mechanism is steel), and when the upper locking bracket 1 is pressed to the bottom, the secondary locking The bending structure 10 on the tightening mechanism 4 presses on the upper locking bracket 1 to play the role of secondary locking.

When the battery chuck is loosened, the secondary locking mechanism 4 needs to be opened first, and the upper locking bracket 1 is lifted up at the same time. Since a supporting structure 7 is designed on the upper locking bracket 1, it is used as a lifting and locking mechanism. The fulcrum of support 1 reduces the lifting moment. When the upper locking bracket 1 is lifted, because the lower locking bracket 2 is made of a material with self-recovery ability, when it exceeds the upper circular structure 8 of the lower locking bracket 2, the lower locking bracket 2 returns to its original shape, The pressing force to the base 5 is eliminated, so that the battery clamp is released.

Further elaborate the design idea of the present invention below in conjunction with the structural diagram of each component:

As shown in Figure 3, it is a schematic diagram of the upper locking bracket of the battery chuck. A cross-like holding structure 6 is designed on both sides of the upper locking bracket 1, and a supporting structure 7 is made in the middle, so that the leverage principle can be used to , reduce the moment of pressing or lifting.

As shown in Figure 4, it is a schematic diagram of the lower locking bracket of the battery chuck. A ring-shaped structure 8 is designed on the lower locking bracket 2, so that the lower locking bracket 2 can shrink. A contraction force is generated on the base, so that the base shrinks, so that it is tightly crimped on the battery pile head. The material of the lower locking bracket has good elasticity, which is convenient for shrinking when the upper locking bracket is crimped, and extended when the upper locking bracket is loosened.

As shown in Figure 5, it is a structural diagram of the plastic sheath of the battery chuck, which is assembled on the upper locking bracket 1 to protect the safety of personnel during operation and will not be scratched by metal.

As shown in Figure 6, it is a schematic diagram of the secondary locking mechanism of the battery chuck. The two positioning holes 9 at the lower end of the secondary locking mechanism are used for positioning and connected to the base or welded together, and through the bending of the upper end of the secondary locking mechanism The structure 10, relying on the elasticity of the metal, is pressed against the upper locking bracket. When it needs to be opened, it is only necessary to open the secondary locking mechanism and lift up the locking bracket, which is convenient and reliable.

As shown in Figure 7, it is the base structure diagram of the battery chuck. On one side of the base of the battery chuck, there is a Y-shaped structure 15, which cooperates with the support structure 7 on the upper locking bracket 1, thereby realizing the lever function ; The circular ring 11 on the base is designed according to the battery pile head, and has a vertebral degree of 1/9. , used to increase the friction between the battery pile head, so as to ensure that the battery chuck will not rotate or loose after being pressed, and will not break under a certain external force, ensuring good contact with the battery pile head. There is a structure 13 for crimping the wiring harness on the base to ensure the convenience of connecting the wiring harness and the battery pile head. For the base of the battery clamp, it needs to be directly connected to the positive or negative pole of the battery, so its material is required to have good electrical conductivity.

Fig. 8 is a structural schematic diagram when the battery clamp is loosened.

The above-mentioned embodiments are only preferred solutions embodying the technical solution of the present invention, and some changes that may be made by those skilled in the art to some parts thereof reflect the principles of the present invention and fall within the scope of protection of the present invention.
