In a specific embodiment, as shown in fig. 5, the fixing mechanism 3 is provided with a locking channel 4.1 for inserting a cylindrical locking pin 2.4, an annular positioning cavity 4.2 is arranged on the side wall of the locking channel 4.1, and the locking assembly 5 is arranged in the annular positioning cavity 4.2.
It should be noted that the locking channel 4.1 may be disposed on the upper fixed side plate 3.2, or the side rib 4 may be disposed on the upper fixed side plate 3.2, and the locking channel 4.1 may be disposed on the side rib 4.
Wherein the number of locking channels 4.1 corresponds to the number of cylindrical locking pins 2.4. When the battery pack 1 is mounted on a vehicle body, the cylindrical locking pins 2.4 are inserted into the locking channels 4.1 in a one-to-one correspondence mode, then the bearing plate 2.1 is driven to move upwards through the jacking device until the arc-shaped locking parts of the cylindrical locking pins 2.4 move to positions corresponding to the annular positioning cavities, and then the locking assemblies 5 positioned in the annular positioning cavities are locked with the arc-shaped locking parts 2.5 in a corresponding mode, so that the fixing mechanism 3 can achieve locking and fixing of the cylindrical locking pins 2.4 and the bearing plate 2.1.
In a specific embodiment, referring to fig. 5-6, the locking assembly 5 comprises a plurality of locking balls 5.1 rollingly arranged in an annular positioning cavity 4.1, the arcuate sides of the locking balls 5.1 being insertable into the arcuate locking portions 2.5.
It should be noted that the plurality of locking steel balls 5.1 are sequentially arranged at intervals along the circumferential direction of the annular positioning cavity 4.2. The locking balls 5.1 are free to roll in the radial direction of the annular positioning cavity 4.2. The arc of the arc-shaped locking part 2.5 is larger than the size of the locking steel ball 5.1, so that during the rolling process of the locking steel ball 5.1, part of the locking steel ball 5.1 can be embedded into the arc-shaped locking part 2.5.
Specifically, when the cylindrical locking pin 2.4 moves to a designated position along the locking channel 4.1, the locking steel ball 5.1 rolls to the arc-shaped locking part 2.5 partially, so that the cylindrical locking pin 2.4 is limited, but at this time, the locking steel ball 5.1 only limits the cylindrical locking pin 2.4, and cannot lock the cylindrical locking pin 2.4, at this time, if pushing or pulling force is applied to the cylindrical locking pin 2.4, the arc-shaped side surface of the arc-shaped locking part 2.5 can press the locking steel ball 5.1, so that the locking steel ball 5.1 moves to the inside of the annular positioning cavity 4.2, further, the locking steel ball 5.1 is separated from the arc-shaped locking part 2.5, and then the cylindrical locking pin 2.4 can still continue to move along the locking channel 4.1.

It should be noted that, in this embodiment, the inclined plane is disposed at the bottom of the annular positioning cavity 4.2, and the inclined plane is disposed obliquely from the annular positioning cavity 4.2 to the locking channel 4.1, that is, the inclined plane is inclined from the edge of the annular positioning cavity 4.2 to the center of the circle, so that the locking steel ball 5.1 can roll to the locking channel 4.1 more quickly, and the power conversion efficiency is improved.
In another preferred embodiment, referring to fig. 6, the present embodiment further comprises an annular restriction 5.3, the annular restriction 5.3 being arranged at the opening of the annular positioning chamber 4.2 for blocking the locking steel ball 5.1 from rolling out of the opening of the annular positioning chamber 4.2.
It should be noted that, in this embodiment, after the bottom of the annular positioning cavity 4.2 is provided with the inclined plane, an annular limiting piece 5.3 is further provided at the opening of the annular positioning cavity 4.2, so as to prevent the locking steel ball 5.1 from rolling out from the opening of the annular positioning cavity 4.2.
It will be appreciated that under the action of gravity, the locking steel balls 5.1 can roll along the inclined plane towards the locking channel 4.1, the annular limiting piece 5.3 blocks and limits the locking steel balls 5.1, the locking steel balls 5.1 are prevented from rolling out of the opening of the annular positioning cavity 4.2, but the arrangement of the annular limiting piece 5.3 does not influence the rolling of one side of the locking steel balls 5.1 into the arc-shaped locking part 2.5.
Specifically, an arc-shaped end part is arranged at one end of the cylindrical locking pin 2.4 far away from the bearing plate 2.1, wherein the arc-shaped end part is arranged above the arc-shaped locking part 2.5, when the full-electric battery pack is installed, the cylindrical locking pin 2.4 moves gradually along the locking channel 4.1, when the arc-shaped end part moves to a position corresponding to the locking steel balls 5.1, the arc-shaped end part pushes each locking steel ball 5.1 to move into the annular positioning cavity 4.2, so that the cylindrical locking pin 2.4 continues to move in the locking channel 4.1, when the cylindrical locking pin 2.4 moves to a preset position, the arc-shaped locking part 2.5 corresponds to the annular positioning cavity 4.2, and the locking steel balls 5.1 roll into the arc-shaped locking part 2.5 along an inclined plane, so that the cylindrical locking pin 2.4 is subjected to positioning limitation.
In a further preferred embodiment, the size of the opening of the annular positioning chamber 4.2 is smaller than the diameter of the locking balls 5.1.
It should be noted that, after the partition plate is provided, the diameter of the opening of the annular positioning cavity 4.2 may be smaller than the diameter of the locking steel ball 5.1, so that the locking steel ball 5.1 may only partially enter the locking channel 4.1 to lock and not fall into the locking channel 4.1. In this embodiment, the installation of the limiting member is not required, so that the locking steel balls 5.1 can be prevented from falling into the locking channel 4.1 from the opening of the annular positioning cavity 4.2 after the installation mechanism 2 is separated from the fixing mechanism 3 when the battery pack 1 is detached.
In another preferred embodiment, referring to fig. 6, the locking device further comprises an annular magnetic attraction piece 5.2, wherein the annular magnetic attraction piece 5.2 is arranged on an annular side wall of the annular positioning cavity 4.2, which is far away from the locking channel 4.1, a magnetic layer is wrapped on the locking steel ball 5.1, and the magnetism of the magnetic layer is the same as that of the annular magnetic attraction piece 5.2.
In this embodiment, by setting the annular magnetic attraction piece 5.2, a certain repulsive force is provided between the annular magnetic attraction piece and the locking steel ball 5.1, so that the locking steel ball 5.1 has a tendency to roll towards the opening of the annular positioning cavity 4.2, and when the cylindrical locking pin 2.4 moves to a preset position, the locking steel ball 5.1 can roll into the arc-shaped locking part 2.5 rapidly, so as to limit the cylindrical locking pin 2.4.
It should be noted that the annular limiting piece 5.3, the annular magnetic attraction piece 5.2 and the magnetic layer do not affect the limitation and locking of the locking steel ball 5.1 to the cylindrical locking pin 2.4.
In another preferred embodiment, the magnetic layer on each locking bead 5.1 is of the same magnetic nature.
In this embodiment, by providing the magnetic layers with the same magnetism on each locking steel ball 5.1, a certain distance can be kept between each locking steel ball 5.1, so that the situation that two or more locking steel balls 5.1 roll together and the locking effect is reduced due to the fact that the gaps between part of two adjacent balls are too large is avoided.

In the locking movement stroke, the annular plate 6.2 receives the drive of the operating unit 7 and moves downwards, and when moving to the first working position, the annular plate 6.2 stretches into the annular positioning cavity 4.2 and presses against the side part of the locking steel ball 5.1, so that the locking steel ball 5.1 is fixed, and in this state, the locking steel ball 5.1 cannot move, and on the basis of this, the connection of the mounting mechanism 2 and the fixing mechanism 3 is completed, namely the mounting of the full-charge battery is completed.
In the unlocking movement stroke, the annular plate 6.2 receives the driving of the operation unit 7 and moves upwards, when the annular plate moves to the second working position, the annular plate 6.2 is completely retracted into the annular movement channel 4.3, the locking steel balls 5.1 only play a limiting role on the cylindrical locking pins 2.4, at the moment, pushing force or pulling force is applied to the cylindrical locking pins 2.4, the arc-shaped side of the arc-shaped locking part 2.5 is pressed against the locking steel balls 5.1, so that the locking steel balls 5.1 move inwards of the annular positioning cavity 4.2, the locking steel balls 5.1 are separated from the arc-shaped locking part 2.5, then the cylindrical locking pins 2.4 are pushed or pulled continuously, and the cylindrical locking pins 2.4 continue to move downwards along the locking channel 4.1 until the cylindrical locking pins are separated from the locking channel 4.1, and the dismounting of the under-powered battery is completed.
Therefore, in this embodiment, by providing the annular plate slidingly connected with the annular movement channel 4.3, the annular plate 6.2 moves up and down along the annular movement channel 4.3, so as to drive the locking steel ball 5.1 to move or fix the locking steel ball 5.1, thereby switching the locking steel ball 5.1 between the locking state and the unlocking state, and completing the locking or unlocking of the battery pack.
In a specific embodiment, referring to fig. 5-7, the operating unit 7 comprises a circular plate 7.1 arranged on top of the annular plate 6.2, and a connecting rod 7.2 fixedly arranged on the circular plate 7.1, the upper end of the connecting rod 7.2 being provided with a driving block 7.3; the fixed mechanism 3 is internally provided with a cylindrical moving cavity 4.4 and a movable channel 4.5 communicated with the cylindrical moving cavity 4.4, and the cylindrical moving cavity 4.4 is communicated with the annular moving channel 4.3; the circular plate 6.2 slides and moves in the cylindrical movement cavity 4.4; the connecting rod 7.2 is movably connected in the movable channel 4.5.
The circular plate 7.1 and the annular plate 6.2 may be of a unitary structure.
In this embodiment, the driving block 7.3 is configured to receive an external driving force, drive the connecting rod 7.2, and drive the circular plate 7.1 to move through the connecting rod 7.2, and further drive the annular plate 6.2 to move through the circular plate.

Wherein, annular plate 6.2, circular plate 7.1 and connecting rod 7.2 fixed connection form the motion structure of integral type. The up-and-down movement of the movement structure correspondingly drives the locking steel ball 5.1 to change between a locking state and an unlocking state, and the specific operation process is as follows:
in the installation process of the full-power battery pack, when the cylindrical locking pins 2.4 move to the preset positions, the locking steel balls 5.1 roll into the arc-shaped locking parts 2.5, then the driving block 7.3 is driven, so that the whole moving structure moves downwards, in the moving process, after the annular plate 6.2 moves from the second working position to the first working position, the annular plate 6.2 abuts against the locking steel balls 5.1, so that the locking steel balls 5.1 cannot move in the annular positioning cavity 4.2, at the moment, the locking steel balls 5.1 are locked with the arc-shaped locking parts 2.5, the locking steel balls 5.1 are locked with the cylindrical locking pins 2.4, and therefore the installation and fixation of the bearing plate 2.1 and the full-power battery pack are completed, and the full-power battery pack is installed on a vehicle body.
When the underpowered battery pack is dismounted, the driving block 7.3 is reversely driven, so that the whole moving structure moves upwards, in the moving process, the annular plate 6.2 moves from the first working position to the second working position, after moving to the second working position, the annular plate 6.2 leaves the annular positioning cavity 4.2 and is stored in the annular moving channel 4.3, at the moment, the pressing force of the annular plate 6.2 on the locking steel balls 5.1 disappears, at the moment, a pulling force is applied to the cylindrical locking pins 2.4, the arc-shaped surface of the arc-shaped positioning part presses the locking steel balls 5.1 to move into the annular positioning cavity 4.2, so that the locking steel balls 5.1 are separated from the cylindrical locking pins 2.4, at the moment, the locking steel balls 5.1 and the cylindrical locking pins 2.4 are in an unlocking state, and the bearing plate 2.1 and the underpowered battery pack can be dismounted.

Specifically, when the undercharged battery pack is dismounted, the driving mechanism 8.1 drives the moving plate 8, so that when each annular plate 6.2 synchronously moves to the second working position, the locking steel balls 5.1 and each cylindrical locking pin 2.4 are in an unlocking state, and the bearing plate 2.1 and the undercharged battery pack can be dismounted. In the process of installing the full-power battery pack, when the cylindrical locking pins 2.4 move to the preset positions, the locking steel balls 5.1 automatically roll into the arc-shaped locking parts 2.5, and then the driving mechanism 8.1 drives the moving plates 8, so that the annular plates 6.2 move to the first working positions, and at the moment, the locking steel balls 5.1 and the cylindrical locking pins 2.4 are simultaneously in a locking state, and the fixation of the cylindrical locking pins 2.4 is realized.
