[0044] As described in the background art, during the hoisting process of the existing battery pack module, the anti-disengagement member that is jointly limited in the hanging hole with the hook body is prone to shift out of the hanging hole due to gravity and shaking, posing a serious risk of safety accidents.

[0045] To improve the above problems, the present application provides a lifting tool 10, which can drive the sliding component 300 to move along the first direction 910 through the locking component 500, so as to jointly abut against and lock in the hanging hole 31 opened in the battery module 30 with the hook body 100, avoiding the sliding component 300 from disengaging from the hanging hole 31 when the center of gravity is unstable due to shaking, thus affecting the hoisting safety.

[0046] Figure 1 Schematic diagram of the working state of the lifting tool 10 provided by the embodiment of the present utility model, Figure 2 provided by the embodiment of the present utility model Figure 1 Enlarged schematic diagram at position A in Figure 3 provided by the embodiment of the present utility model Figure 1 Enlarged schematic diagram at position B in, please refer to Figures 1 to 3 , the present application provides a lifting tool 10, which includes a hook body 100, a sliding component 300, and a locking component 500.

[0047] Among them, as Figure 4 and Figure 5 shown, the hook body 100 is used to abut against the hanging hole 31 opened in the battery module 30, and the hook body 100 is provided with a channel 111 extending along the first direction 910. And, the sliding component 300 is slidably connected to the channel 111, so as to always reciprocate along the first direction 910 under the guiding action of the channel 111. On the basis of the above settings, the locking component 500 is located in the channel 111 and connected to the sliding component 300, and is used to drive the sliding component 300 to move along the first direction 910, so that the sliding component 300 and the hook body 100 jointly abut against and lock in the hanging hole 31. In addition, it should be noted that the above-mentioned hanging hole 31 is specifically the Figure 2 and Figure 3 C-shaped iron hanging hole 31 shown in.

[0048] Specifically, before hoisting the battery module 30, the operator moves the sliding component 300 in the reverse direction along the first direction 910, so that the hook body 100 can be pre-positioned in the hanging hole 31 alone in advance. After that, the operator releases the sliding component 300. At this time, the locking component 500 drives the sliding component 300 to move along the first direction 910, so that the sliding component 300 and the hook body 100 are jointly abutted and limited in the hanging hole 31. It can be understood that in the above process, the force applied by the locking component 500 to the sliding component 300 is always a force moving along the first direction 910 (that is, downward). That is to say, the locking component 500 always locks the sliding component 300 in the hanging hole 31. Even if there is shaking or collision, it still ensures that the sliding component 300 is located in the hanging hole 31 and will not shift or disengage.

[0049] Please refer to Figure 6 , Figure 6 which is a schematic diagram of the locking component 500 and the positioning component provided by the embodiment of the present invention. Next, the sliding component 300 and the locking component 500 will be explained in detail. In some embodiments, the sliding component 300 includes a sliding member 310 and a limiting member 330. Among them, the sliding member 310 is connected to the locking component 500 and is slidably connected to the channel 111 to move along the first direction 910 under the action of the locking component 500. The limiting member 330 is connected to the sliding member 310 and is used to jointly abut against the hook body 100 in the hanging hole 31 opened in the battery module 30.

[0050] It can be understood that the sliding member 310 is located inside the channel 111, and the limiting member 330 is located outside the channel 111. Under the action of the locking component 500 also located in the channel 111, the sliding member 310 drives the limiting member 330 to move along the first direction 910 relative to the hook body 100 together, without causing impact or influence on the hook body 100, ensuring that the hook body 100 can cooperate with the limiting member 330 to improve the safety of the subsequent hoisting module.

[0051] To ensure that the sliding member 310 can slide smoothly along the first direction 910 without obstruction, a positioning groove is opened on the side of the sliding member 310 away from the limiting member 330. The sliding component 300 further includes an anti-disengagement member 350 that cooperates with the positioning groove, and the anti-disengagement member 350 abuts against the edge of the channel 111. Based on this, it also means that the anti-disengagement member 350 and the limiting member 330 located on both sides of the hook assembly limit the sliding member 310 in the channel 111 to prevent it from disengaging and causing the locking component 500 to fail. Optionally, the sliding member 310, the positioning groove, and the limiting member 330 are integrally formed.

[0052] Furthermore, as Figure 7As shown, in order to improve the positioning function of the hook body 100, in some embodiments, the hook body 100 includes a hook portion 110 with a groove 111 and a positioning portion 130 connected to the hook portion 110. The positioning portion 130 is used to penetrate the hole wall of the hanging hole 31, that is, the hook portion 110 is positioned and abutted against the hanging hole 31 through the positioning portion 130. In addition, the positioning portion 130 and the limiting member 330 are respectively located on two opposite sides of the hook body 100 along the second direction 930 to avoid collision or interference between the two, and at the same time achieve the purpose of increasing the limiting size in the second direction 930. It can be understood that the second direction 930 is perpendicular to the first direction 910.

[0053] On the basis of the above, further, the sum of the lengths of the stopper 330, the hook portion 110 and the positioning portion 130 extending along the second direction 930 is greater than the length of the hanging hole 31 extending along the second direction 930. Based on this, it is ensured to the greatest extent that when the stopper 330 is located in the hanging hole 31, the sling 10 will not slip out of the hanging hole 31. In addition, in order to facilitate the connection between the sling 10 and the hanging rope, a through hole 117 is provided at one end of the hook body 100 away from the locking assembly 500, and the through hole 117 is used to connect with the hanging rope.

[0054] In order to facilitate the disassembly and assembly of the lifting device 10 and the lifting hole 31, Figure 6 As shown, the sliding assembly 300 further includes a disassembly buckle 370, which is connected to the limiting member 330 and is used to drive the limiting member 330 to move in the opposite direction along the first direction 910 under the action of an external force. In other words, the operator pulls the disassembly buckle 370 to overcome the force of the locking assembly 500, and drives the limiting member 330 to move in the opposite direction along the first direction 910 and detach from the hanging hole 31. At this time, there is plenty of room for movement in the hanging hole 31 along the second direction 930, which facilitates the operator to remove the hook body 100 from the hanging hole 31, thereby separating the sling 10 from the hanging hole 31.

[0055] Please refer again Figure 7 Next, the relationship between the hook body 100 and the locking assembly 500 will be described in detail. In some embodiments, the locking assembly 500 includes a connecting pin 510 and an elastic member 530. The connecting pin 510 is connected to the sliding assembly 300, and one end of the elastic member 530 is connected to the connecting pin 510, and the other end extends along the first direction 910 and is connected to the groove wall of the groove 111.

[0056] Based on the above arrangement, it can be understood that the central axis of the elastic member 530 extends along the first direction 910, and it can exert an action of moving along the first direction 910 (i.e., downward) on the connecting pin 510 through its own restoring force, thereby being able to drive the sliding assembly 300 connected to the connecting pin 510 to move along the first direction 910 together, until the sliding assembly 300 enters the hanging hole 31. Optionally, in order to improve the connection strength between the elastic member 530 and the groove wall of the groove 111, the locking assembly 500 further includes a positioning pin 550, and the elastic member 530 is connected to the groove wall of the groove 111 through the positioning pin 550. Specifically, the positioning pin 550 can be vertically connected to the bottom end of the groove 111, or both ends can be horizontally connected to the side walls of the groove 111, which will not be described in detail here.

[0057] To ensure the locking effect of the locking assembly 500, Figure 7 As shown, the channel 111 includes a slide groove 113 and a mounting groove 115, the slide groove 113 is arranged through the hook body 100, and the sliding assembly 300 is slidably connected with the slide groove 113. The mounting groove 115 is recessed in the hook body 100, and the slide groove 113 is connected with the mounting groove 115 along the first direction 910, the elastic member 530 is located in the mounting groove 115, and the groove wall of the mounting groove 115 close to one end of the slide groove 113 is used to abut against the sliding assembly 300. Based on the above arrangement, it can be understood that when the sliding assembly 300 enters the hanging hole 31, the groove wall of the mounting groove 115 will abut against and limit the sliding assembly 300. At this time, the elastic member 530 still exerts a downward force on the sliding assembly 300 to ensure that when there is no external force in the opposite direction along the first direction 910, the sliding assembly 300 is always located in the hanging hole 31, and abuts against and limits together with the hook body 100.

[0058] Taking this embodiment as an example, the working principle and workflow of the sling 10 provided in this application are as follows:

[0059] Before hoisting the battery module 30, the operator pulls the disassembly buckle 370 to move the limiter 330 in the opposite direction along the first direction 910, so that the hook portion 110 can be positioned and abutted against the hanging hole 31 through the positioning portion 130. Afterwards, the operator releases the disassembly buckle 370, and the elastic member 530 drives the sliding assembly 300 to move along the first direction 910, so that the sliding member 310 moves into the hanging hole 31 and abuts against the groove wall of the mounting groove 115 to limit the position. At this time, the limiter 330 and the hook body 100 are abutted and limited in the hanging hole 31 together, and are always subjected to the downward force applied by the elastic member 530. Based on the above settings, it can be seen that at this time, the sling 10 and the hanging hole 31 are in an inseparable state, achieving self-locking. After the hoisting is completed, repeat the above actions to remove the sling 10 for the next hoisting operation.

[0060] In summary, the present application provides a lifting tool 10, which includes a hook body 100, a sliding assembly 300, and a locking assembly 500. Among them, the hook body 100 is used to abut against a lifting hole 31 formed in the battery module 30, and the hook body 100 is provided with a channel 111 extending along the first direction 910. Moreover, the sliding assembly 300 is slidably connected to the channel 111, so that under the guiding action of the channel 111, it always reciprocates along the first direction 910. On the basis of the above settings, the locking assembly 500 is located in the channel 111 and connected to the sliding assembly 300, and is used to drive the sliding assembly 300 to move along the first direction 910, so that the sliding assembly 300 and the hook body 100 together abut against and lock in the lifting hole 31. It can be understood that since the force applied by the locking assembly 500 to the sliding assembly 300 is always along the first direction 910, the purpose of constantly locking the sliding assembly 300 in the lifting hole 31 can be achieved, ensuring that even if there is shaking or collision, the sliding assembly 300 always remains in the lifting hole 31 and will not shift or disengage.

[0061] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
