Good practical performance, safe and reliable.

Preferably, the power device is a motor, and a control device for controlling the operation of the power device is fixed on the frame, or it can be other power devices, and the motor has good stability and reliability.

Preferably, an electromagnet and a stop device are also fixed on the frame at the other end of the rotating shaft, and the electromagnet and the stopping device ensure that the rotating shaft is fixed at a position when locking, ensuring the reliability of the locking baffle when locking Well, the safety features are better.

Preferably, the control device is a two-position selector switch, and it can also be other control devices that are convenient for controlling the operation of the power unit. The two-position selector switch has a simple structure and good use effect.

Preferably, the cross-section of the locking baffle is L-shaped, the horizontal plane of the locking baffle is arranged parallel to the frame body, the vertical surface of the locking baffle is connected to the rotating shaft, and it can also be other convenient processing The shape of the L shape is simple, the use effect is good, and the locking effect is good.

To sum up, the advantages of the present invention are: through the power unit driving the locking device on the frame, the automatic control of lithium battery locking is realized, which greatly improves the original manual operation, low battery access efficiency and There are no problems such as unsafe factors of the locking mechanism, which creates a foundation for realizing the cooperation with the robot, and the use effect is good.

Description of drawings

The present invention will be further described below in conjunction with accompanying drawing:

Fig. 1 is a schematic structural view of the locking mechanism of the lithium battery charging stand of the present invention.

Detailed ways

As shown in Figure 1, the locking mechanism of the lithium battery charging stand includes a frame body 1, a locking device 2 is provided in the middle of the frame body 1, and a driving locking device 2 is fixed on the frame body 1 to lock or loosen. The power unit 5 is opened, and the frame body 1 is also provided with a limiting device for controlling the power unit 5 to stop. The locking device 2 is a locking baffle, and the locking baffle is connected to the frame body through a rotating shaft 6. 1, the power device 5 is fixed on the frame body 1 at one end of the rotating shaft 6, and it can also be other locking structures that are convenient for locking, and the locking baffle is locked and released by driving the rotating shaft 6 with the power device 5, The structure is simple and the operation is simple. The limiting device includes a cam 4 rotatably connected to the rotating shaft 6 and a travel switch 3 fixed on the frame body 1. The cam 4 is in contact with the travel switch 3. It can also be other limiting devices, such as a cam 4 Rotation is in contact with the travel switch 3, the structure is simple, the practical performance is good, safe and reliable, the power device 5 is a motor, and the control device 7 for controlling the operation of the power device 5 is also fixed on the frame body 1, and it can also be used for other power devices. Device 5, the motor has good stability and reliability. An electromagnet 8 and a stopper 9 are also fixed on the frame body 1 at the other end of the rotating shaft 6. The stopper is an iron block. The device ensures that the rotating shaft is fixed at one position when locking, and ensures good reliability and better safety performance when the locking baffle is locked. The control device 7 is a two-position selector switch, which can also be used for other convenient control power devices 5.
