[0040] To better understand the purpose, structure, and function of this utility model, a more detailed description of this utility model is provided below with reference to the accompanying drawings.

[0041] Example 1

[0042] See Figure 1a , Figure 1b As shown, the gripping mechanism provided in this embodiment is characterized by including a mounting plate 11 and two sets of gripping parts 12 correspondingly arranged at both ends of the bottom of the mounting plate 11;

[0043] The gripping part 12 includes an electric push rod 121, a first sliding assembly 122, and a snap-fit ​​assembly 123;

[0044] The fixed ends of the first sliding assembly 122 and the electric push rod 121 are both installed at the bottom of the mounting plate 11;

[0045] The sliding direction of the first sliding component 122 is the same as the extension and retraction direction of the output end of the electric actuator 121;

[0046] The snap-fit ​​assembly 123 is mounted on the first sliding assembly 122 and connected to the output end of the electric actuator 121.

[0047] Specifically, the two gripping parts 12 cooperate with each other and can hold the side wall of the battery 5 through the two sets of snap-fit ​​components 123, so as to facilitate the subsequent pushing and pulling of the battery 5.

[0048] Specifically, such as Figure 1a As shown, the snap-fit ​​assembly 123 includes a clamping arm 1231 and a snap-fit ​​piece 1232;

[0049] The clamping arm 1231 is mounted on the first sliding assembly 122 and connected to the output end of the electric push rod 121;

[0050] The clip 1232 is installed on the end of the clamping arm 1231 away from the first sliding assembly 122 and is located on the opposite surface of the two sets of clamping arms 1231.

[0051] Specifically, the clip 1232 in this embodiment is designed to hold the groove on the side wall of the battery 5. Most existing batteries 58 have grooves on their side walls to facilitate gripping the battery 5. This embodiment takes into account this feature and allows the clip 1232 to be inserted into the groove. The clip 1232 is moved horizontally by the electric push rod 121, thereby holding the battery 5 in the groove or releasing it.

[0052] In addition, see Figure 1a The gripping unit 12 also includes a positioning sensor 124 and two sets of sensors 125;

[0053] Two sets of sensors 125 are sequentially mounted on the mounting plate 11 along the sliding direction of the first sliding assembly 122;

[0054] The positioning sensor 124 is mounted on the snap-fit ​​assembly 123 and moves back and forth between the two sets of sensors 125 via the first sliding assembly 122.

[0055] Specifically, by using the cooperation of sensor 125 and positioning sensor 124, the moving distance of the snap-fit ​​assembly 123 can be adjusted more accurately, so that the translation amount of the snap-fit ​​1232 can be adapted to the depth of the groove on the side wall of the battery 5.

[0056] Example 2

[0057] See Figure 2a , Figure 2b As shown, this embodiment provides a transfer device, including a gripping mechanism 1 as provided in Embodiment 1, a drive assembly 2, and a mounting frame 3;

[0058] Both ends of the mounting plate 11 are slidably connected to the top ends of the mounting bracket 3 via the second sliding assembly 4;

[0059] The sliding direction of the second sliding component 4 is perpendicular to the sliding direction of the first sliding component 122;

[0060] The drive assembly 2 includes a drive motor 21 mounted on the top of the mounting frame 3 and a belt 223 conveyor 22 arranged along the sliding direction of the second sliding assembly 4.

[0061] The output end of the drive motor 21 is connected to the belt 223 transmission section 22;

[0062] Mounting plate 11 is connected to belt 223 transmission section 22 via belt clamp 6.

[0063] Specifically, the drive motor 21 drives the belt 223 transmission unit 22 to drive the mounting plate 11 to move accordingly, and the second sliding component 4 guides the movement and provides a basis for the movement.

[0064] It should be noted that both the first sliding component 122 and the second sliding component 4 are combinations of sliders and rails, and the connection objects of the sliders and rails can be selected according to the actual situation.

[0065] Specifically, see Figure 2b The belt 223 transmission unit 22 can be a combination of a drive pulley 221, a driven pulley 222, and a belt 223 sleeved between the drive pulley 221 and the driven pulley 222. The drive pulley 221 is driven by a drive motor 21, causing the belt 223 to rotate. A belt clamping member 6 is provided on the mounting plate 11 to clamp the belt 223, thereby enabling the drive motor 21 to drive the belt 223 to rotate. The belt 223 then moves the mounting plate 11 horizontally. This allows the gripping mechanism 1 to "grab" the battery 5, and the drive assembly 2 to move the gripping mechanism 1 horizontally, thus pulling the battery 5 into the mounting frame 3. (See reference...) Figure 3 The illustration.

[0066] In addition, to facilitate the entry and exit of the battery 5 into and out of the mounting bracket 3, a drive mechanism that can move the battery 5 can be added to the bottom of the mounting bracket 3, such as various drive rollers.

[0067] Example 3

[0068] This embodiment provides a battery swapping cabinet, including a transfer device as provided in Embodiment 2.

[0069] Specifically, this embodiment completely transfers the function of the battery drive device on the AGV to the transfer device (inside the battery swapping cabinet), so that the AGV does not need to be equipped with a drive device, thereby simplifying the structure of the AGV and reducing manufacturing and maintenance costs.

[0070] This document uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. Furthermore, those skilled in the art will recognize that, based on the ideas of this utility model, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this utility model.
