[0045] Please refer to Figure 1-Figure 3 , Figure 1 A schematic diagram of the structure of a hoisting system 300 provided in an embodiment of the utility model; Figure 2 A schematic diagram of the structure of the lifting tool 100 provided by an embodiment of the utility model at a first viewing angle; Figure 3 This is a schematic structural diagram of the lifting tool 100 provided in an embodiment of the utility model at a second viewing angle.

[0046] An embodiment of the utility model provides a lifting system 300, which includes a crane (not shown), a battery pack 200 and a lifting tool 100. The crane is connected to the lifting tool 100. The crane can position the battery pack 200 through the lifting tool 100 and clamp or release the battery pack 200.

[0047] The hoisting tool 100 will be described in detail below:

[0048] Please refer to Figure 1-Figure 3 The lifting tool 100 includes a support frame 110, two clamping assemblies 120 and two positioning assemblies 130. The two clamping assemblies 120 are connected to the support frame 110, and the two clamping assemblies 120 move along a preset direction. The two positioning assemblies 130 are located between the two clamping assemblies 120, and the two positioning assemblies 130 are connected to the support frame 110.

[0049] Specifically, the two positioning assemblies 130 act on opposite sides of the battery pack 200 to position the battery pack 200, thereby confirming the clamping position of the battery pack 200. After confirming the position of the battery pack 200, the two clamping assemblies 120 approach each other along a preset direction to clamp the battery pack 200. Subsequently, the battery pack 200 is moved by a crane to move the battery pack 200 from the clamping position to the destination position. Finally, the two clamping assemblies 120 move away from each other to release the battery pack 200, and the crane moves upward, so that the positioning assembly 130 leaves the battery pack 200. In this way, the assembly or unloading of the battery pack 200 is completed.

[0050] It should be noted that, in the process of the clamping assembly 120 approaching the battery pack 200, since the positioning assembly 130 acts on both sides of the battery pack 200 and the positioning assembly 130 is located between the two clamping assemblies 120, it can be understood that the positioning assembly 130 is located between the battery pack 200 and the clamping assembly. Therefore, in order to avoid the positioning assembly 130 affecting the clamping of the battery pack 200 by the clamping assembly 120, the clamping assembly 120 and the positioning assembly 130 are staggered, thereby improving the stability of the clamping and the lifting efficiency.

[0051] For further information, please refer to Figure 1-Figure 6 , Figure 4 A schematic diagram of the structure of a clamping assembly 120 provided in an embodiment of the utility model; Figure 5 A schematic diagram of the structure of a battery pack 200 provided in an embodiment of the present utility model; Figure 6 for Figure 5 A partial enlarged view of point A in the middle.

[0052] The clamping assembly 120 includes a clamping plate 121 and at least one hook 122; the clamping plate 121 is movably connected to the support frame 110; the hook 122 is connected to the clamping plate 121 for clamping one side of the battery pack 200; the hook 122 is connected to the clamping plate 121; wherein, the clamping plate 121 is provided with an avoidance portion 123, and the avoidance portion 123 is used to avoid the positioning assembly 130.

[0053] The battery pack 200 includes two end plates 210 , which are respectively disposed at two opposite ends of the battery pack 200 . The end plates 210 are provided with at least one through hole 212 , and each through hole 212 corresponds to a hook 122 .

[0054] Specifically, the two clamping plates 121 approach each other along a preset direction, that is, the clamping plates 121 approach the battery pack 200 , thereby driving the hook 122 to approach the end plate 210 , so that the hook 122 passes through the through hole 212 and cooperates with the end plate 210 .

[0055] After the clamping plate 121 and the end plate 210 are fitted, that is, the two clamping plates 121 clamp the battery pack 200, they act as a mechanism to drive the lifting tool 100 to move upward, so that the hook 122 hooks the end plate 210, thereby improving the clamping stability and preventing the battery pack 200 from detaching.

[0056] In order to prevent the positioning assembly 130 from affecting the clamping of the clamping plate 121, an avoidance portion 123 is provided to avoid the positioning assembly 130. In this embodiment, the avoidance portion 123 is an avoidance hole, so that when the clamping plate 121 approaches the battery pack 200, the positioning assembly 130 can pass through the avoidance hole to avoid affecting the clamping and improve the stability of the clamping. In other embodiments, the avoidance portion 123 can also be an avoidance groove, etc.

[0057] According to the above configuration, the clamping assembly 120 further includes a linear bearing 125, which is sleeved on the support frame 110 and connected to the clamping plate 121. Specifically, the lifting tool 100 plays a guiding role by providing the linear bearing 125, so that the clamping plate 121 can move along a preset direction, thereby preventing the support frame 110 from being misaligned in its moving direction, resulting in poor clamping effect on the battery pack 200, and preventing the battery pack 200 from being detached.

[0058] For further information, please refer to Figure 1-Figure 8 , Figure 7 A schematic diagram of the structure of the positioning assembly 130 provided in an embodiment of the utility model from a first viewing angle; Figure 8 This is a schematic structural diagram of the positioning assembly 130 provided in an embodiment of the utility model from a second viewing angle.

[0059] The positioning assembly 130 includes a load-bearing bracket 131, a connecting member 132 and at least one positioning pin 133; the load-bearing bracket 131 is connected to the support frame 110; the load-bearing bracket 131 and the positioning pin 133 are both connected to the connecting member 132; the extension direction of the positioning pin 133 is perpendicular to the preset direction.

[0060] It should be noted that, in this embodiment, the preset direction is the horizontal direction, and the extending direction of the positioning pin 133 is the vertical direction.

[0061] Specifically, in the present embodiment, the connecting member 132 is located between the load-bearing bracket 131 and the clamping plate 121, that is, the connecting member 132 is connected to the side of the load-bearing bracket 131. Among them, the positioning pin 133 is connected to the bottom of the connecting member 132. The crane is connected to the load-bearing bracket 131. In the process of assembling or disassembling the battery pack 200, the crane drives the positioning assembly 130 to move downward close to the battery pack 200, so that the positioning pin 133 is inserted into the positioning groove 211 on the end plate 210 of the battery pack 200, thereby positioning the battery pack 200. After positioning the clamping station of the battery pack 200, the two clamping plates 121 approach each other along a preset direction to adhere to the battery pack 200, thereby preventing the sides of the clamping plates 121 from being in contact with the battery pack 200, thereby improving the stability of the clamping and the lifting efficiency, and preventing the battery pack 200 from being detached.

[0062] Based on the above settings, please refer to Figure 1-Figure 8 The lifting tool 100 further includes a screw rod 140 and a drive motor 150. One end of the screw rod 140 is connected to the drive motor 150, and the drive motor 150 is connected to the clamping plate 121, wherein the extension direction of the screw rod 140 is parallel to the preset direction. The drive motor 150 drives the clamping plate 121 to move along the extension direction of the screw rod 140, that is, along the preset direction, so that the two clamping plates 121 can move closer to each other to clamp the battery pack 200, or move away from each other to release the battery pack 200.

[0063] It should be noted that, in this embodiment, the connecting member 132 is provided with a receiving groove 1322, and a sensor is placed in the receiving groove 1322. After the positioning pin 133 is inserted into the positioning groove 211, the sensor sends a signal to the drive motor 150, so that the drive motor 150 rotates to drive the clamping plate 121 to approach the battery pack 200, thereby clamping the battery pack 200, realizing automatic control, and ensuring the personal safety of the staff.

[0064] Specifically, in this embodiment, the connecting member 132 is provided with a first clearance hole 1321; the clamping plate 121 is provided with a second clearance hole 124; the load-bearing bracket 131 is provided with a third clearance hole 1314; the other end of the screw rod 140 passes through the first clearance hole 1321, the second clearance hole 124 and the third clearance hole 1314, and the screw rod 140 is movably matched with the first clearance hole 1321, the second clearance hole 124 and the third clearance hole 1314, so that the clamping plate 121 moves towards or away from the connecting member 132 during the movement. Since the positioning pin 133 has been inserted into the positioning groove 211, that is, the battery pack 200 has been positioned, the clamping plate 121 moves toward the connecting member 132, that is, it moves toward the battery pack 200, so that the clamping plate 121 can clamp the battery pack 200, thereby improving the clamping stability and hoisting efficiency.

[0065] In this embodiment, since the connecting member 132 is connected to the side of the load-bearing bracket 131, the load-bearing bracket 131 is provided with a third clearance groove to make way for the screw rod 140. In other embodiments, for example, the connecting member 132 is connected to the bottom of the load-bearing bracket 131, and only the first clearance hole 1321 and the second clearance hole 124 may be provided.

[0066] For further information, please refer to Figure 1-Figure 8 The load-bearing bracket 131 includes two support arms 1311, and the extension direction of the two support arms 1311 is perpendicular to the extension direction of the screw rod 140; one ends of the two support arms 1311 are connected to each other; the first clearance hole 1321 is located at the connection of the two support arms 1311. The lifting tool 100 includes two support rods 111 arranged in parallel; the other ends of the two load-bearing brackets 131 are each provided with a mounting hole 1313; each support rod 111 is movably matched with one mounting hole 1313.

[0067] It should be noted that the preset direction is the extension direction of the support rod 111. Therefore, the extension direction of the positioning pin 133 is perpendicular to the extension direction of the support rod 111, and the extension direction of the screw rod 140 is parallel to the extension direction of the support rod 111.

[0068] Specifically, in this embodiment, two support arms 1311 are provided to improve the support effect of the load-bearing bracket 131, thereby improving the stability of the lifting tool 100. It should be noted that in this embodiment, the load-bearing bracket 131 is arched, the first clearance hole 1321 is located in the middle of the load-bearing bracket 131, and the installation holes 1313 are located at both ends of the load-bearing bracket 131; that is, the connecting member 132 is located in the middle of the load-bearing bracket 131, and the support frame 110 is connected to both ends of the load-bearing bracket 131.

[0069] It can be understood that the load-bearing bracket 131 is a symmetrical structure. In addition, in this embodiment, the clamping assembly 120 is provided with two linear bearings 125 , and each linear bearing 125 is sleeved on a support frame 110 .

[0070] According to the above content, in this embodiment, the load-bearing bracket 131 is provided with a hanging hole 1312, which is located directly above the first clearance hole 1321 and is used to cooperate with the crane, thereby ensuring the stability of the hoisting tool 100 and the battery pack 200 during the movement.

[0071] For further information, please refer to Figure 1-Figure 8 The lifting tool 100 is provided with a plurality of stoppers 160, each stopper 160 being sleeved on one end of the support frame 110. In this embodiment, the lifting tool 100 is provided with two support frames 110, thereby providing four stoppers 160 to prevent the clamping plate 121 from being separated from the support frame 110 during movement.

[0072] Based on the above, please refer to Figure 1-Figure 8 In this embodiment, the clamping assembly 120 further includes a handle 126, which is connected to the clamping plate 121, and the handle 126 and the hook 122 are respectively located on opposite sides of the clamping plate 121. When installing the lifting tool 100, the staff can take the clamping plate 121 through the handle 126, so as to facilitate the assembly of the lifting tool 100.

[0073] Please refer to Fig. 9 , Fig. 9 A schematic diagram of the structure of the lifting tool 100 provided in the third perspective of the embodiment of the utility model. The lifting tool 100 also includes a control module 170 and a connecting rod 180, the connecting rod 180 is connected to the positioning assembly 130, and the control module 170 is arranged on the connecting rod 180. After the battery pack 200 is moved to the target station, the battery pack 200 needs to be released, so that the drive motor 150 is controlled by the control module 170 to drive the splint 121 to move to release the battery pack 200. In addition, the control module 170 drives the crane to move upward, so that the positioning pin 133 leaves the positioning groove 211, thereby completing the assembly and disassembly of the battery pack 200.

[0074] In this embodiment, the connecting rod 180 extends in a direction perpendicular to the support frame 110 so that there is a certain distance between the control module 170 and the positioning assembly 130 and the clamping plate, that is, there is a certain distance between the control module 170 and the battery pack 200, thereby avoiding danger to the staff when operating the control module 170 and ensuring the safety of the staff.

[0075] In summary, the lifting tool 100 includes a support frame 110, two clamping assemblies 120 and two positioning assemblies 130. The two positioning assemblies 130 are located between the two clamping assemblies 120. Each positioning assembly 130 is connected to the support frame 110. The two positioning assemblies 130 act on the opposite sides of the battery pack 200 respectively to position the battery pack 200.

[0076] The positioning assembly 130 includes a load-bearing bracket 131 and a positioning pin 133. The load-bearing bracket 131 is provided with a lifting hole 1312, which is connected to a crane. The crane drives the positioning assembly 130 to move downward so that the positioning pin 133 and the positioning groove 211 on the end plate 210 are matched, thereby positioning the battery pack 200. After the positioning pin 133 is inserted into the positioning groove 211, the sensor on the connecting member 132 sends a signal to the driving motor 150, and the driving motor 150 drives the clamping plate 121 to move.

[0077] The two clamping assemblies 120 and the support frame 110 are movably connected, and the two clamping assemblies 120 move along the direction of the support frame 110, so that the two clamping assemblies 120 are moved closer to each other to clamp the battery pack 200 or the two clamping assemblies 120 are moved away from each other to release the battery pack 200, thereby assembling or disassembling the battery pack 200.

[0078] The clamping assembly 120 is provided with a clamping plate 121 and a hook 122. The clamping plate 121 is provided with an avoidance portion 123, so as to avoid the positioning assembly 130, so as to avoid the positioning assembly 130 from affecting the clamping assembly 120, so as to improve the stability of clamping. The positioning assembly 130 and the clamping assembly 120 can be staggered.

[0079] The hook 122 cooperates with the through hole 212 on the battery pack 200. When the crane drives the lifting tool 100 to move upward, the hook 122 can hook the end plate 210 of the battery pack 200, thereby increasing the stability of the clamping.

[0080] Thus, the position of the battery pack 200 can be located, and the battery pack 200 can be clamped or released to assemble or disassemble the battery pack 200, thereby improving the clamping stability and the lifting efficiency.
