[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0034] like Figures 1 to 5 As shown, an embodiment of the present invention provides a battery pack 30 transfer device, which includes: a receiving component 10, having a receiving portion and a first side 11 and a second side 12 arranged opposite to each other, the receiving portion being used to receive the battery pack 30 to be transferred, and the battery pack 30 can move along the first side 11 toward the second side 12 or along the second side 12 toward the first side 11; a traction component 20, having a connecting portion, a traction portion and a traction rope, the connecting portion is connected to the traction portion, and the traction component 20 is used to connect with the battery pack 30 through the connecting portion, one end of the traction rope is fixed on the first side 11 of the receiving component 10, and the other end of the traction rope passes around the traction portion and makes part of the traction rope fit and connected to the outer wall of the traction portion, and the traction rope is configured to enable the battery pack 30 to move from the second side 12 toward the first side 11.

[0035] By applying the technical solution of the present invention, when the battery pack 30 needs to enter the cluster, the battery pack 30 is first placed on the receiving part, and then the receiving part is moved to the cluster entrance of the battery pack 30, the battery pack 30 is pushed and moved along the first side 11 toward the second side 12, so that the battery pack 30 is moved to the installation position to meet the cluster entry requirement of the battery pack 30. When the battery pack 30 needs to leave the cluster, the connecting part of the traction component 20 is connected to the battery pack 30, and the traction part of the traction component 20 is used in conjunction with the traction rope to move the battery pack 30 along the second side 12 toward the first side 11 to the receiving part to meet the cluster exit requirement of the battery pack 30. In this way, the cluster entry and exit requirements of the battery pack 30 can be met at the same time, the transportation efficiency of the battery pack 30 is improved, and the user's usage needs are met.

[0036] In one embodiment, the traction assembly 20 includes a housing 21 having a receiving slot 22 for connecting to the battery pack 30; a first pulley 23 rotatably disposed within the receiving slot 22. The first pulley 23 forms a traction portion, with at least a portion of the traction rope lapped onto the pulley slot of the first pulley 23. In this application, the first pulley 23 is equivalent to a movable pulley. The first pulley 23 can move simultaneously with the battery pack 30 along the second side 12 toward the first side 11. Because the movable pulley is essentially a lever with a power arm equal to twice the resistance arm (a labor-saving lever), it can save effort, making it easier for the user to remove the battery pack 30 from the cluster, thereby improving the efficiency of removing the battery pack 30 from the cluster.

[0037] In one embodiment, the rotation axis of the first pulley 23 forms an angle with the moving direction of the battery pack 30. This arrangement can adjust the moving direction of the battery pack 30, thereby improving the moving efficiency of the battery pack 30.

[0038] In one embodiment, the angle is a right angle. Optionally, the angle can also be set to other angles, and the specific setting should be set according to actual use requirements, which can improve the applicability and scope of application of the device.

[0039] In one embodiment, the traction assembly 20 further includes a first frame 24 disposed between the battery pack 30 and the housing 21. The first frame 24 has a connecting portion, one end of which is movably connected to the housing 21. The first frame 24 protects the housing 21 from direct force, thereby protecting the structure of the housing 21 and extending the service life of the housing 21.

[0040] In one embodiment, the first frame 24 has a triangular cross-section along the direction from the first side 11 toward the second side 12. Because the triangle shape provides stability, the first frame 24 is less likely to deform or tilt during operation when the battery pack 30 is towed, effectively improving the durability of the first frame 24 and reducing the cost of using the first frame 24.

[0041] In one embodiment, the triangle is an isosceles triangle. Because the three vertices of an isosceles triangle support each other, forming a stable structure, the first frame 24 is less likely to deform or tilt when subjected to pressure. Furthermore, an isosceles triangle exhibits central symmetry, meaning that a line connecting the vertices to the midpoint of the base (i.e., the altitude, median, and angle bisector) can be divided into two identical parts. This symmetry not only facilitates the processing of the first frame 24 but also correspondingly improves its structural strength.

[0042] In one embodiment, the first frame 24 includes a first section 25, a second section 26, and a third section 27, which are connected end to end. The first and second sections 25, 26 form the hypotenuse of an isosceles triangle, and the third section 27 forms the base of the isosceles triangle. Connecting posts 29 are provided at each end of the third section 27. The connecting posts 29 form a connecting portion and are configured to engage with connecting holes 31 on the battery pack 30. This simple structure improves the connection efficiency between the first frame 24 and the battery pack 30, thereby facilitating assembly and disassembly of the first frame 24 and the battery pack 30.

[0043] In one embodiment, the first frame 24 further includes a reinforcement section 28. A reinforcement section 28 is provided between the first section 25 and the third section 27, and between the second section 26 and the third section. One end of the reinforcement section 28 is connected to the third section 27, and the other end of the reinforcement section 28 is connected to the first section 25 or the second section 26. The reinforcement section 28 can further improve the overall structural strength of the first frame 24, thereby extending the service life of the first frame 24 as much as possible.

[0044] In one embodiment, the connecting portion is connected to the side wall of the battery pack 30 facing the first side 11. This configuration facilitates assembly and disassembly of the connecting portion and the battery pack 30, thereby maximizing the efficiency of the battery pack 30.

[0045] In one embodiment, the receiving assembly 10 includes a second frame 13 having a first side 11 and a second side 12; and a roller 14 rotatably mounted on the second frame 13. The roller 14 forms a receiving portion. When the battery pack 30 moves on the roller 14, the roller 14 can rotate relative to the battery pack 30. This arrangement can reduce friction during the movement of the battery pack 30, thereby improving the movement efficiency of the battery pack 30 and facilitating rapid entry and exit of the battery pack 30.

[0046] In one embodiment, the rotation axis of the roller 14 is perpendicular to the direction from the first side 11 to the second side 12. This arrangement can maximize the moving efficiency of the battery pack 30 to meet the use requirements of the device.

[0047] In one embodiment, the receiving assembly 10 includes a plurality of rollers 14 arranged along the first side 11 toward the second side 12. The plurality of rollers 14 further reduces the contact area between the rollers 14 and the battery pack 30, thereby minimizing friction during movement of the battery pack 30 and facilitating rapid movement of the battery pack 30 into and out of the cluster.

[0048] In one embodiment, the receiving assembly 10 further includes a second pulley 15 rotatably disposed on the first side 11 of the second frame 13. The traction rope cooperates with the first pulley 23 and the second pulley 15 to move the battery pack 30 from the second side 12 toward the first side 11. In this application, the second pulley 15 is a fixed pulley. By cooperating with the first pulley 23, it not only saves effort but also changes the direction of the force, thereby meeting the movement requirements of the battery pack 30.

[0049] In one embodiment, the rotation axis of the second pulley 15 is parallel to the rotation axis of the roller 14. This arrangement can maximize the stability of the battery pack 30 during movement, thereby ensuring that the battery pack 30 does not fall from the first frame 24 during movement, thereby improving the safety of the battery pack 30 during movement.

[0050] In one embodiment, the first side 11 of the second frame 13 is further provided with fixing holes 16, which correspond to the connection holes 31 on the battery pack 30. Fasteners are sequentially inserted through the fixing holes 16 and the connection holes 31 to secure the battery pack 30 to the second frame 13. This improves the stability of the connection between the battery pack 30 and the second frame 13, thereby minimizing the risk of the battery pack 30 falling during transportation.

[0051] In one embodiment, the receiving assembly 10 further includes a lifting ring 17, which is arranged along the circumference of the second frame 13. The lifting ring 17 is used to connect with an external assembly to lift the second frame 13. When the battery pack 30 is inserted into the cluster, the battery pack 30 is first placed on the roller, and then the fixing parts are sequentially connected to the fixing holes 16 and the connection holes 31 to fix the battery pack 30 to the second frame 13. Then, the lifting hook is hooked on the four lifting rings 17, and the battery pack 30 is lifted to the cluster entrance of the battery pack 30 (a forklift can also be used). Then, the fixing parts are removed and the battery pack 30 is pushed into the installation position.

[0052] By applying the technical solution of the present invention, when the battery pack 30 needs to enter the cluster, the battery pack 30 is first placed on the receiving part, and then the receiving part is moved to the cluster entrance of the battery pack 30, the battery pack 30 is pushed and moved along the first side 11 toward the second side 12, so that the battery pack 30 is moved to the installation position to meet the cluster entry requirement of the battery pack 30. When the battery pack 30 needs to leave the cluster, the connecting part of the traction component 20 is connected to the battery pack 30, and the traction part of the traction component 20 is used in conjunction with the traction rope to move the battery pack 30 along the second side 12 toward the first side 11 to the receiving part to meet the cluster exit requirement of the battery pack 30. In this way, the cluster entry and exit requirements of the battery pack 30 can be met at the same time, the transportation efficiency of the battery pack 30 is improved, and the user's usage needs are met.
