Two guide blocks 104 are arranged side by side below each guide plate 105, wherein the guide blocks 104 near the middle of the battery compartment 200 are positioned in the grooves of the connecting bracket 602. The connection brackets 602 are provided with 2 sets along the length direction of the corresponding guide block 104.
Specifically, the translation device includes a connection block 701 connected to the rotation shaft 601, a translation guide assembly disposed between the power changing compartment 200 and the frame 100, and a translation driving assembly disposed between the connection block 701 and the frame 100. The function of the swivel shaft 601 is to position the battery compartment 200 to provide a center of rotation and to provide translational power to the battery compartment 200. The translation drive assembly includes a translation screw 702 disposed on top of the carriage 100 and threadably coupled to the connection block 701. The translating screw 702 is connected to the carriage 100 through a bearing mount. Translation of the battery changing bin 200 is achieved through a screw rod and nut transmission structure. A translation driving hand wheel 703 is installed at one or both ends of the translation screw 702 so that the screw can be driven to rotate no matter which side of the frame 100; a motor may be mounted at one end of the translation screw 702 to achieve electrical adjustment.
The translation guide assembly comprises a guide block 104 arranged at the top of the frame 100 and a guide plate 105 limited between the power changing bin 200 and the guide block 104. The guide blocks 104 in each set of translation guide assemblies are arranged 2 side by side on top of the carriage 100 and provided with translation guide grooves on the top surface, and the bottom of the guide plate 105 is provided with translation guide blocks (not shown) which are matched with the translation guide grooves in the two guide blocks 104. The connection bracket 602 is arranged on the battery changing bin 200, and the weight of the whole battery changing bin 200 is transferred to the guide block 104 of the frame 100 through the connection bracket 602 and the guide plate 105.

The swing driving assembly comprises two connecting brackets 602 fixed on the power changing bin 200, an arc-shaped rack 603 fixed in the middle of a cross beam 608 connecting the two connecting brackets 602 and taking a swing shaft 601 as a rotation center, a driving rack 604 meshed with the arc-shaped rack 603, and an intermediate transmission assembly arranged between the guide plate 105 and the driving rack 604. Because the rotatable angle of the battery compartment 200 in the vehicle frame 100 is not large, the arc-shaped rack 603 occupies a central angle of 6 ° -10 ° (i.e., the rotatable angle of the battery compartment 200 in the vehicle frame 100 is ±3 ° -5 °). The intermediate transmission assembly comprises a rotary screw 605 rotatably arranged on the guide plate 105 through a bearing seat, a nut 606 matched with the rotary screw 605, and a driving rack 604 fixed on the nut 606. The guide plate 105 is provided with a guide plate for guiding the nut 606, and the top of the guide plate is positioned in a guide groove at the bottom of the nut 606. A support seat matched with the rotary screw rod 605 and a rotary driving hand wheel 607 connected with the rotary screw rod 605 through a bevel gear transmission assembly are arranged on the guide plate 105. The nut 606 horizontally moves through rotating the rotary driving hand wheel 607, so that the rack 604 is driven to drive the arc-shaped rack 603 to rotate along the arc-shaped groove 105-1, and the purpose that the battery compartment 200 rotates around the rotary shaft 601 is achieved; a driving motor connected to the rotary screw 605 may be provided to the guide plate 105 to drive the motor.
An arc-shaped groove 105-1 with a rotation center of a rotation shaft 601 is provided on the top surface of the guide plate 105, and a rotation guide block (not shown) located in the arc-shaped groove 105-1 is provided on the connection bracket 602. When the battery compartment 200 translates, the rotary guide block is used for driving the guide plate 105 to translate by being matched with the arc-shaped groove 105-1; when the battery compartment 200 rotates, the rotary guide block is matched with the arc-shaped groove 105-1 to realize the guide function.
When the battery compartment 200 is required to rotate, the rotary driving hand wheel 607 is rotated to enable the rotary screw 605 to rotate, and the driving rack 604 is used for driving the arc-shaped rack 603 to rotate by taking the rotary shaft 601 as a rotation center, so that the guide structure between the connecting support 602 and the guide plate 105 can ensure that the battery compartment 200 rotates stably.
When the battery compartment 200 is required to translate, the translation driving hand wheel 703 is rotated to enable the translation screw rod 702 to rotate, so that the connection block 701 and the rotary shaft 601 drive the battery compartment 200 to translate, and in the process, the battery compartment 200 synchronously drives the guide plate 105 to horizontally move through the rotary guide block on the connection support 602, so that the translation of the battery compartment 200 is realized.
