The front end of the threaded screw rod 34 is fixedly provided with a bolt 35, and the tail end of the threaded screw rod 34 can be rotationally connected with the front end plate through a bearing. The distal end of the threaded screw 34 is inserted into and secured to the inner race of the bearing, thereby allowing only relative rotation between the threaded screw 34 and the front end plate, thereby ensuring that the threaded screw 34 can also move the front end plate along the length of the frame 30 while rotating.

The central axis of the bolt 35 is close to or intersects with the central axis of the screw rod 34, and the central axis of the bolt 35 is perpendicular to the central axis of the screw rod 34, wherein both ends of the bolt 35 extend out of the screw rod 34 in equal length.

The battery restraint tray can be driven to perform restraint or restraint releasing actions by controlling the forward rotation or the reverse rotation of the output shaft of the driving motor 29.

When the driving motor 29 and the battery restraint tray are required to be separated, the driving cylinder 27 is only required to be started to drive the driving motor 29 to move towards the direction away from the battery restraint tray.

As shown in fig. 6a and 9, in the present embodiment, a first position detecting module 38 and a second position detecting module 39 are disposed on the mounting platform 2, wherein an induction piece 40 is disposed at the bottom of the front end plate of the battery restraint tray, and both the first position detecting module 38 and the second position detecting module 39 can induce with the induction piece 40. The first and second position detection modules 38, 39 may be proximity switches, such as hall proximity switches, or the like.

When the clamping plate 32 of the battery restraining tray is at the restraining-releasing position, the sensing piece 40 moves to the sensing range of the first position detecting module 38, and at this time, the first position detecting module 38 is triggered; when the clamping plate 32 of the battery restraining tray is at the restraining position, the sensing piece 40 moves to the sensing range of the second position detecting module 39, and at this time, the second position detecting module 39 is triggered.

In this embodiment, the battery restraint device further includes a lifting mechanism, where the lifting mechanism is used to lift the battery in the battery restraint tray located on the lifting mechanism. The lifting mechanism can jack up the battery in the accommodation space outside the accommodation space, wherein the height of the battery which is jacked up can be adjusted through the lifting mechanism.

As shown in fig. 16, the lifting mechanism includes a jacking module 41, a lifting cylinder 42 and a mounting plate 43, wherein the jacking module 41 is fixedly arranged on the top surface of the mounting plate 43, and a piston of the lifting cylinder 42 is connected with the bottom surface of the mounting plate 43. The bottom of the lifting cylinder 42 may be fixedly connected to the housing 1.

The lifting mechanism comprises two lifting motors which are respectively arranged at two ends of the length direction of the mounting plate 43, wherein the two lifting motors of the lifting mechanism synchronously lift and have the same lifting height.

Referring to fig. 9 and 13, the battery restraining tray includes a plurality of receiving spaces for receiving the batteries, and insertion through holes 44 are provided at the bottoms of the receiving spaces.

The insertion through holes 44 are used for inserting the jacking modules 41 therein, and the jacking modules 41 are in one-to-one correspondence with the accommodation spaces. When the battery restraint tray is horizontally placed on the jacking mechanism, the top of each jacking module 41 is opposite to the insertion through hole 44 of the corresponding accommodating space.

To ensure the stability of the jacking, the jacking module 41 comprises at least two jacking rods 45 arranged in parallel. Wherein, the insertion through holes 44 at the bottom of the accommodating space are in one-to-one correspondence with the ejector rods 45 of the jacking module 41.

In this embodiment, two insertion through holes 44 are provided at the bottom of each accommodation space, and each jack-up module 41 includes two jack rods 45.

Since the battery restraint tray in this embodiment is provided with two restraint modules 31, two sets of lifting mechanisms are shown. Wherein each set of lifting mechanisms is independently controlled.

The side or top surface of the shell of the battery restraint machine can be provided with a door opening, and the door opening is provided with a door plate for opening and closing the door opening. When the battery in the tray of the electricity Chi Jushu needs to be taken out, the battery in the battery restraint tray on the jacking mechanism can be jacked up by the lifting mechanism, and then the battery is taken out through the door opening, wherein the battery can be taken out by a mechanical arm or a manual work. When the batteries are all taken away, the empty battery restraint tray can be sent out from the feeding port through the conveying mechanism, or the battery restraint tray can be taken out from the door opening through the mechanical arm.

In this embodiment, a battery restraint workstation is further provided, including a temporary storage platform and the battery restraint device, where the temporary storage platform is used to store a battery restraint tray to be entered into the battery restraint device.

The temporary storage platform can be close to the parking of the feed inlet of the battery restraint machine, wherein a battery restraint tray to be entered into the battery restraint machine is placed on the temporary storage platform in advance, so that workers can push the battery restraint tray into the feed inlet conveniently.
