[0031] As shown, Figures 1-4 The principle of the low-voltage power-on and power-off power management system provided by the embodiment is as follows: when the device is used, the power supply protection shell 1 should be taken out first, then the power supply protection shell 1 is installed at the position required for work, then the low-voltage power supply body 2 is placed in the power supply protection shell 1, then the protective cover 3 is installed on the power supply protection shell 1 through bolts, and finally the synchronous head-tail control switch 4 is installed on the protective cover 3 through bolts, at this time, it is ensured that the positive and negative poles of the synchronous head-tail control switch 4 are consistent with the positive and negative poles of the low-voltage power supply body 2, and at this time, the external other controllers are connected in series through the positive wire 8 and the negative wire 24.
[0032] When the synchronous head-tail control switch 4 starts work, the electric telescopic rod 6 will be stretched out synchronously, at this time, the stretched electric telescopic rod 6 will push the fixed seat 9 to move downward until it is clamped in the clamping seat groove 16, in this process, the first foolproof insertion block 13 will be inserted into the first foolproof insertion groove 18 first, at the same time, the second foolproof insertion block 15 will be inserted into the second foolproof insertion groove 21 first, then the first insertion end 26 will be inserted into the first insertion end groove 19, and at the same time, the second insertion end 27 will be inserted into the second insertion end groove 22, so that the protection of the first insertion end 26 and the second insertion end 27 before electrical connection can be realized, at this time, a low-voltage power-on and power-off closed loop circuit with the low-voltage power supply body 2 as the center is completed, and the positive wire 8 and the negative wire 24 cooperate with each other to facilitate the external other controllers to realize electrical connection with the low-voltage power supply body 2 through the synchronous head-tail control switch 4.
[0033] When the synchronization head-tail control switch 4 stops working, the electric telescopic rods 6 will be retracted synchronously, and the fixed seat 9 will move upward to disengage from the clamping seat groove 16 to the initial position. In this process, the first insertion terminal 26 will first disengage from the first insertion terminal slot 19 to return to the initial position, and the second insertion terminal 27 will also first disengage from the second insertion terminal slot 22 to return to the initial position. Then, the first foolproof plug 13 will disengage from the first foolproof plug slot 18 to return to the initial position, and the second foolproof plug 15 will also disengage from the second foolproof plug slot 21 to return to the initial position. Thus, the protection of the first insertion terminal 26 and the second insertion terminal 27 before electrical disconnection can be achieved. At this time, the bidirectional disconnection of the low-voltage power supply body 2 is completed, and the positive wire 8 and the negative wire 24 cooperate with each other to facilitate the external controller to realize the bidirectional electrical disconnection with the low-voltage power supply body 2 through the synchronization head-tail control switch 4.
[0034] When the synchronization head-tail control switch 4 is working, the positive wire 8 and the negative wire 24 are always in a relaxed state, so that the positive wire 8 and the negative wire 24 will not be pulled violently when the synchronization head-tail control switch 4 is working.
[0035] This allows the synchronization head-tail control switch 4 to quickly perform low-voltage power-on and low-voltage power-off operations according to the predetermined program of the device after receiving the instruction. Since the low-voltage power supply body 2 is connected to the positive and negative poles synchronously, the connection can be disconnected bidirectionally, thereby increasing the safety and reliability of the connection.
