[0024] When the module tray 1, carrying the pressurized battery module, flows along the line to the workstation that needs to be unlocked, the lifting and positioning mechanism 7 rises, lifting and positioning the module tray 1. At this time, the cylinder 6 extends, driving the male connector assembly 5 to move upward and insert it into the female connector assembly 4 to connect with the pneumatic guide rail lock 2. At this time, the cylinder 6 intakes air and pushes the two end plates 3 to move to the sides and separate from the battery module to relieve the pressure on the battery module and facilitate the next process. Since the female connector assembly 4 and the male connector assembly 5 are arranged up and down, the reliability of the connection between the male connector assembly 5 and the female connector assembly 4 is guaranteed.

[0025] Example 2

[0026] from Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 It can be seen that the automatic plug-in unlocking device of the present invention: the female connector assembly 4 includes a female connector 41, which is fixed under the module tray 1; the male connector assembly 5 includes a male connector 51, which is connected to the rod end of the cylinder 6.

[0027] Since the female connector 41 and the male connector 51 are arranged up and down, and the male connector 51 and the female connector 41 are floatingly connected, when the cylinder 6 extends upward, the air nozzle on the male connector 51 is reliably inserted into the inner hole of the female connector 41.

[0028] Example 3

[0029] from Figure 5 、 Figure 6It can be seen that the automatic plug-in unlocking device of the present invention: the female connector assembly also includes two upper mounting seats 42 and two guide grooves 43, the upper mounting seats 42 are respectively fixed to the front and rear ends of the female connector 41, and each upper mounting seat 42 is provided with a guide groove 43; the male connector assembly also includes two lower mounting seats 52 and two guide blocks 53, the two lower mounting seats 52 are respectively fixed to the front and rear ends of the male connector 51, and each lower mounting seat 52 is provided with a guide block 53, and the guide block 53 has the same shape as the guide groove 43 and is slightly smaller in size than the guide groove.

[0030] When the cylinder 6 extends upward, the guide block 53 first moves upward along the guide groove 43 to provide guidance, and the air nozzle on the male connector 51 is then inserted into the inner hole of the female connector 41 and connected with the guide rail lock 2. At this time, the cylinder 6 intakes air to push the two end plates 3 to move to both sides and separate from the battery module, thereby relieving the pressure on the battery module and facilitating the next process.

[0031] Example 4

[0032] from Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 It can be seen that in the automatic plug-in unlocking device of the present invention, the guide groove 43 is square; and the cross-section of the guide block 53 is square.

[0033] The automatic plug-in unlocking device of the present invention has the following features: the guide groove 43 is circular; and the cross-section of the guide block 53 is also circular.
