That is, the sliding shaft 115 includes a thick section that is sleeved with the return spring 116 and a thin section that is correspondingly inserted into the first push sliding hole 131 or the second push sliding hole 151, and the connection between the thin section and the thick section forms abutment surface that can be pressed, so that the transmission driving force can be abutted.

[0092] Through the above structure, the synchronous locking control of two lock heads 11 in a locking assembly can be achieved through a group of first transmission long rods 13, second transmission long rods 15, and one-way locking components 16, which can effectively reduce the number of parts and components, simplify the structural cost through linkage control, reduce the operation steps, and reduce the difficulty and complexity of operation.

[0093] More specifically, refer to Figure 1-7 In some embodiments, the locking drive assembly 52 includes two linear lifters arranged on the frame 51. The linear lifters correspond to the push plates 17 one by one, and the output ends of the linear lifters are located directly below the corresponding push plates 17, thereby automatically driving the push plates 17 to move. The structure is simple and the cost is low. The linear lifters can be linear oil cylinders or linear air cylinders, etc.

[0094] More specifically, in some embodiments, reference Figure 1-7 The one-way locking assembly 16 includes two ratchets 161 and at least one ratchet 162. The first transmission rod 13 and the second transmission rod 15 are respectively fixed with ratchets 161 coaxial with the central axis 14; at least one ratchet 162 is arranged on the carrier 12, and the ratchet 162 is used to cooperate with each ratchet 161 in a one-way locking manner, so that the first transmission rod 13 and the second transmission rod 13 can only move in one direction in the direction of pushing the corresponding sliding shaft 115. Therefore, when the power battery 200 is loaded as described above, the buckle portion 21 of the tray 2 is locked with the buckle portion 1121 of the locking claw auxiliary component 1, and then the power battery 200 is installed and locked; the pawl 162 maintains a one-way locking fit with the ratchet 161, and at this time, the push plate 17 can be pushed by the linear lifter, and then the push plate 17 synchronously pushes the first transmission long rod 13 and the second transmission long rod 15 to drive the corresponding lock head 11 to perform a locking movement, and finally the buckle portion 21 of the tray 2 is locked with the buckle portion 1121 of the locking claw auxiliary component 1 and cannot be unlocked; and in the above-mentioned loading of the power battery 200, that is Adjust the locking portion 1121 of the locking claw auxiliary component 1 so that the locking portion 1121 performs an unlocking action, and then the locking portion 1121 of the locking claw auxiliary component 1 is unlocked and separated from the locking portion 1121 of the locking claw auxiliary component 1, and unlocking is achieved; there is no need to use a linear lifter, and the pawl 162 is directly moved to release the one-way locking cooperation with the ratchet 161. At this time, under the action of the reset spring 116, the stop slider 114 is reset to the first position, and then the stop slider 114 releases the contact with the anti-rotation protrusion 1122 of the lock disk 112, so that the lock disk 112 can move to the unlocking position, and finally complete the unlocking.

[0095] Finally, it should be noted that the various technical features of the above embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the various technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0096] The above embodiment only expresses one implementation of the present invention, and its description is relatively specific and detailed, but it cannot be understood as limiting the scope of the invention patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
