[0047] Example one

[0048] Referring to Figures 1-2 The embodiment provides a rotating clamping piece, which comprises a main body 11 provided with an inner cavity, a rotating motor 12 and a clamping piece 13.

[0049] The rotating motor 12 and the clamping piece 13 are located at opposite sides of the main body 11 respectively.

[0050] The clamping piece 13 comprises a base 14 and a spring plate 15.

[0051] The rotating rod 16 is arranged on the base 14, the self-rebound spring 17 is sleeved on the rotating rod 16, and one free end of the self-rebound spring 17 abuts against the base 14.

[0052] The elastic plate 15 is arranged on the rotating rod 16 and abuts against the other free end of the self-rebound spring 17.

[0053] The output end of the rotating motor 12 penetrates into the inner cavity of the main body 11.

[0054] The rotating sleeve column 18 is connected to the upper portion of the base 14.

[0055] One end of the rotating sleeve column 18 penetrates into the inner cavity of the main body 11 and is sleeved on the output end of the rotating motor 12.

[0056] It should be noted that, as shown in Figure 2 The size of the base 14 is slightly larger than that of the elastic plate 15, so as to accommodate the elastic plate 15 into the base 14.

[0057] Specifically, the rotating clamping piece 1 of the embodiment is used to clamp the groove on the side wall of the battery 8. The side wall of the existing battery 8 is mostly provided with a groove, which is used to facilitate the grasping of the battery 8. The embodiment is aimed at this feature, and the clamping piece 13 can be clamped into the groove. Specifically, as shown in Figure 2 When the rotating clamping piece 1 moves towards the battery 8, the elastic plate 15 will retract into the base 14 due to the inclined surface of the elastic plate 15, and the self-rebound spring 17 will be compressed. When the elastic plate 15 enters the groove, the elastic plate 15 will be ejected under the action of the self-rebound spring 17, and the groove will be clamped, which is convenient for subsequent dragging of the battery 8.

[0058] Embodiment Two

[0059] As shown in Figure 3 The embodiment provides a transfer mechanism, which comprises two rotating clamping pieces 1 provided in the embodiment, a driving assembly 3, and a mounting rack 4.

[0060] The mounting rack 4 is arranged on the driving assembly 3.

[0061] The two rotating clamping pieces 1 are arranged at two end positions on the same side of the mounting rack 4.

[0062] Specifically, the mounting rack 4 cooperates with the two rotating clamping pieces 1 to realize the grasping of the battery 8, and then the battery 8 is transferred under the driving of the driving assembly 3, so as to drive the battery 8 to move.

[0063] Specifically, the driving assembly 3 comprises a plane rack body 31, a driving motor 32, a driving wheel 33, a driven wheel 34, and a belt 35.

[0064] The driving motor 32 and the driven wheel 34 are installed on the plane frame body 31 correspondingly;

[0065] The output end of the driving motor 32 is sleeved with the driving wheel 33;

[0066] The driving wheel 33 and the driven wheel 34 are connected through the belt 35;

[0067] The belt 35 is connected and installed through the connecting block connecting frame 4.

[0068] The driving motor 32 drives the driving wheel 33 to rotate, and then the belt 35 can also be driven to move under the cooperation of the driven wheel 34, thereby driving the installation frame 4 to move.

[0069] Specifically, the plane frame body 31 is also provided with two groups of sliding assemblies 5;

[0070] The two groups of sliding assemblies 5 are located on the left and right sides of the belt 35;

[0071] The arrangement direction of the sliding assembly 5 is the same as the transmission direction of the belt 35;

[0072] The installation frame 4 is connected with the two groups of sliding assemblies 5 respectively.

[0073] Specifically, the sliding assembly 5 can be a slidingly matched sliding rail and sliding block, as Figure 3 shown, the sliding rail is installed on the plane frame body 31, and the installation frame 4 is connected with the sliding block through the connecting plate, so as to realize the movement guidance of the installation frame 4.

[0074] Embodiment three

[0075] Referring to Figure 4 shown, the embodiment provides a battery transfer device, which comprises a transfer mechanism 2 provided in the embodiment two.

[0076] Specifically, the battery transfer device is installed with the transfer mechanism 2 on the side facing the battery 8, and the transfer mechanism is installed on the frame body of the battery transfer device. When it is needed to "grab" the battery 8, the battery can be grabbed and "transferred" through the transfer mechanism, so as to realize the movement of the battery driven by the battery transfer device. Specifically, a driving mechanism capable of cooperating with the transfer mechanism 2 to completely pull the battery 8 into the battery transfer device can also be arranged on the battery transfer device. In the embodiment, the specific structure of the driving mechanism will not be described too much, and the structure shown in Figure 4 can be referred to.

[0077] Embodiment four

[0078] The embodiment provides a battery replacement cabinet, which comprises a battery 8 transfer device provided in the embodiment three.

[0079] Specifically, the embodiment realizes complete transfer of the function of the battery driving device on the AGV to the battery transfer device (in the battery replacement cabinet), so that the AGV does not need to be provided with a driving device, thereby simplifying the structure of the AGV and reducing manufacturing and maintenance costs.

[0080] It should be noted that when the rotating clamping piece 1 clamps the groove of the battery and drags the battery to move, the battery is taken by other devices inside the battery replacement cabinet after being positioned, and the battery continues to move in the original moving direction, and the rotating clamping piece 1 is released from the groove by inertia. When the process of sending the battery out of the battery replacement cabinet needs to be performed, the rotating motor 12 drives the clamping piece 13 to rotate, and then clamps the groove of the battery 8 or is released from the groove by the same principle.

[0081] In addition, it should be noted that, as shown in Figure 5 The rotating motor 12 can be a double-output-shaft motor, one shaft of which penetrates into the main body 11, and the other shaft can be connected with a sensor 6, and two receivers 7 corresponding to the sensor are arranged on both sides of the shaft, so that when the two shafts of the rotating motor 12 rotate synchronously, the number of degrees of rotation of the rotating motor 12 can be known through the sensor 6. Since the battery enters and exits the battery replacement cabinet, the rotating clamping piece 13 needs to be “flipped”, so it needs to be rotated by 180 degrees, which can better control the angle of rotation of the rotating motor 12 driving the clamping piece 13, and ensure that it is rotated in place every time.

[0082] In this paper, specific examples are applied to explain the principles and implementation modes of the utility model, and the above examples are only used to help understand the method and core idea of the utility model; at the same time, for those skilled in the art, according to the idea of the utility model, the specific implementation mode and application range will be changed. In conclusion, the content of the specification should not be understood as a limitation of the utility model.
