Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0031] The present application proposes a sling 100, which is used for lifting and transporting battery modules. Figures 1 to 3 In the embodiment of the present application, the hanger 100 includes a hanger frame 10 and a plurality of hook assemblies 20 arranged at intervals on the hanger frame 10. The number of the hook assemblies 20 is generally set according to the size and / or mass of the battery module. In some examples, the hanger 100 includes four hook assemblies 20, and the four hook assemblies 20 are respectively matched with the four corners of the battery module; in some examples, the hanger 100 includes six hook assemblies 20, wherein four hook assemblies 20 are respectively matched with the four corners of the battery module, and the remaining two hook assemblies 20 are matched with the middle part of the battery module in the length direction.

[0032] The lifting frame 10 is used to connect with the lifting equipment. Each hook assembly 20 includes a mounting frame 21 and a movable pin 22. The mounting frame 21 is provided with mounting portions 211 and abutment portions 213 at intervals along its length direction. A clamping position 212 for placing a battery frame is formed between the mounting portion 211 and the abutment portion 213. The movable pin 22 is slidably installed on the mounting portion 211 so that one end of the movable pin 22 can move toward or away from the abutment portion 213 along the length direction of the mounting frame 21.

[0033] The hanging frame 10 is usually provided with a lifting ring to cooperate with the hook of the hanging equipment. Considering the limited lifting power of the hanging equipment, the hanging frame 10 is usually frame-shaped and adopts a hollow structure.

[0034] It should be emphasized that the height of the clamping position 212 is greater than the thickness of the battery frame, that is, the distance between the mounting portion 211 and the abutment portion 213 is greater than the thickness of the battery frame in the vertical direction, so that the battery frame can be placed in the clamping position 212 for the movable pin 22 to cooperate with the pin hole of the battery frame; wherein, the abutment portion 213 is located below the battery frame and plays the role of supporting the battery frame.

[0035] The present application adopts the above-mentioned technical scheme, and a clamping position 212 for placing the battery frame is formed between the mounting portion 211 and the abutment portion 213 of the mounting frame 21, and the movable pin 22 is slidably installed on the mounting portion 211. When the battery frame is placed in the clamping position 212, one end of the movable pin 22 moves along the length direction of the mounting frame 21 toward the abutment portion 213, and the movable pin 22 can be inserted into the pin hole of the battery frame, limiting the horizontal movement of the battery frame relative to the mounting frame 21, thereby preventing the battery module from detaching from the hanger 100. When the battery module is transported to the designated position and is taken over by a new carrying device, one end of the movable pin 22 moves along the length direction of the mounting frame 21 toward away from the abutment portion 213, and the movable pin 22 can be detached from the pin hole of the battery frame, and the hanger 100 can be taken away. It can be seen that compared with the prior art, the technical solution of the present application does not require manual alignment of the limit holes on the mounting plate with the pin holes when installing the sling 100. As long as the movable pin 22 is aligned with the pin hole, the installation operation of the sling 100 can be completed quickly and conveniently by directly driving one end of the movable pin 22 along the length direction of the mounting frame 21 toward the abutment portion 213 to complete the plug-in cooperation operation with the pin hole. This improves the installation efficiency of the sling 100 and the transportation efficiency of the battery module.

[0036] In some examples, such as Figures 1 to 3 As shown, each hook assembly 20 further includes a handle 23 , which is connected to the movable pin 22 . The handle 23 is used to drive the movable pin 22 to move back and forth in the length direction of the mounting frame 21 .

[0037] With such arrangement, a worker using the sling 100 can drive the movable pin 22 to move back and forth in the length direction of the mounting frame 21 through the handle 23 , so as to further improve the worker's installation efficiency of the sling 100 .

[0038] In some examples, such as Figure 2 and Figure 3 As shown, the handle 23 includes a rotating part 232 and a short rod 231 and a long rod 233 connected at both ends of the rotating part 232. The rotating part 232 is rotatably mounted on the mounting frame 21, and the short rod 231 is connected to the movable pin 22, so that when the long rod 233 is subjected to external force, the short rod 231 can drive the movable pin 22 to move back and forth in the length direction of the mounting frame 21.

[0039] In this way, the worker can drive the movable pin 22 to move back and forth in the length direction of the mounting frame 21 through the short rod 231 by operating the long rod 233. Since the short rod 231 is shorter than the long rod 233, the worker can operate the handle 23 with less force, thereby improving the comfort of operating the handle 23.

[0040] Considering that the rotating part 232 of the handle 23 is rotatably mounted on the mounting frame 21, when the worker operates the long rod 233, the movement trajectory of the end of the short rod 231 away from the rotating part 232 is arc-shaped, while the movable pin 22 moves along the length direction of the mounting frame 21, and its movement trajectory is linear.

[0041] In some examples, such as Figure 3 As shown, a connecting column 221 is convexly provided on the peripheral side of the movable pin 22, a connecting plate 234 is provided at one end of the short rod 231 away from the rotating part 232, and the connecting plate 234 is provided with a groove 235 that is clearance-matched with the connecting column 221. Such a configuration is intended to further improve the comfort of the control handle 23.

[0042] Preferably, in some examples, each hook assembly 20 further includes an elastic member, which is elastically installed between the movable pin 22 and the mounting frame 21 so that the movable pin 22 has a tendency to move closer to the abutment portion 213 .

[0043] With such a configuration, when the movable pin 22 is inserted into the pin hole, the movable pin 22 is not easy to be separated from the pin hole under the action of the elastic member, thereby reducing the possibility that the movable pin 22 is affected by external factors and causes the battery module to be separated. At the same time, it is also convenient for the hanger 100 to be installed or removed from the battery frame.

[0044] In some examples, the mounting frame 21 is further provided with a power assist rod on one side of the long rod 233 , and when a worker operates the long rod 233 , the worker can use the resistance rod to leverage the force to further improve the comfort of the operating handle 23 .

[0045] In some examples, such as Figure 3 As shown, the abutment portion 213 is provided with a convex column 214 that cooperates with the pin hole of the battery frame. In this way, when the battery frame is placed in the clamping position 212, the convex column 214 can play a role in positioning and aligning, so that the movable pin 22 is plugged and matched with the pin hole.

[0046] In some examples, such as Figure 1 As shown, the hanging frame 10 includes a hanging plate assembly 11 and at least two hook connection modules 12. The hanging plate assembly 11 includes a hanging plate 111 and a first hanging chain 112. The two ends of the first hanging chain 112 are respectively connected to the two ends of the hanging plate 111, and the middle part of the first hanging chain 112 is used to connect with the hanging equipment. The top ends of at least two hook connection modules 12 are respectively detachably connected to the hanging plate 111, and at least two hook connection modules 12 are spaced apart in the length direction of the hanging plate 111. The bottom end of each hook connection module 12 is also connected to two hook assemblies 20, and the two hook assemblies 20 are respectively located on both sides of the hanging plate 111.

[0047] In some examples, a plurality of card holes are provided in the length direction of the hanging plate 111, and at least two hook connection modules 12 are detachably connected to the plurality of card holes. Specifically, a card block that is plugged into the card hole is provided on the top of the hook connection module 12.

[0048] In other examples, the tops of at least two hook connection modules 12 are slidably connected to the hanging plate 111, and the tops of at least two hook connection modules 12 are provided with locking members, which act on the tops of the hook connection modules 12 and the hanging plate 111 to lock or unlock the tops of the hook connection modules 12 and the hanging plate 111.

[0049] With such arrangement, at least two hook connection modules 12 can adjust the spacing in the length direction of the hanging plate 111 , so that the hanger 100 of the present application can be suitable for battery modules of different lengths.

[0050] In some examples, such as Figures 1 to 5 As shown, each hook connection module 12 includes a second lifting chain 121, an adjusting component 122 and two fixing blocks 123. The top end of the second lifting chain 121 is detachably connected to the hanging plate 111. The bottom end of the second lifting chain 121 includes two sub-chains 1211. The ends of the two sub-chains 1211 away from the hanging plate 111 are respectively connected to a hook component 20. A fixing block 123 is fixedly provided on each sub-chain 1211. The adjusting components 122 are respectively connected to the two fixing blocks 123 and act on the two fixing blocks 123 to adjust the spacing between the two hook components 20 on the second lifting chain 121 by adjusting the spacing between the two fixing blocks 123.

[0051] Such a configuration is intended to enable the hanger 100 of the present application to be applicable to battery modules of different widths.

[0052] In some examples, such as Figure 1 As shown, the adjustment assembly 122 includes a first adjustment plate 1221, and the first adjustment plate 1221 is provided with a plurality of first adjustment parts 1222 at intervals along its length direction, and the two fixing blocks 123 can be detachably connected to any first adjustment part 1222. In some examples, the first adjustment part 1222 is a card hole, and the positioning block is plugged into the card hole.

[0053] With such a configuration, workers can adjust the spacing between the two hook assemblies 20 on the second lifting chain 121 by adjusting the two fixing blocks 123 to be detachably connected with different first adjustment parts 1222, so that the lifting device 100 of the present application can be suitable for battery modules with different widths.

[0054] In some examples, such as Figure 4 and Figure 5As shown, the adjustment assembly 122 includes two second adjustment plates 1223 and a fixing member 1225. The two second adjustment plates 1223 are fixedly connected to the inner sides of the two fixing blocks 123, respectively. The two second adjustment plates 1223 are each provided with a plurality of second adjustment portions 1224 spaced apart along their length direction. The fixing member 1225 can be detachably connected to any second adjustment portion 1224 of the two second adjustment plates 1223, respectively.

[0055] In some examples, the fixing member 1225 includes a sleeve and two positioning pins. The sleeve is provided with two through holes. The second adjustment portions 1224 on the two second adjustment plates 1223 are both card holes. When parts of the two second adjustment plates 1223 are accommodated in the sleeve, the two positioning pins are respectively plugged into and matched with the corresponding card holes through the two through holes.

[0056] In another example, the fixing member 1225 is provided with a receiving groove for accommodating the two second adjustment plates 1223, and two positioning columns are protruding from the bottom of the receiving groove. The second adjustment portions 1224 on the two second adjustment plates 1223 are both card holes. When parts of the two second adjustment plates 1223 are accommodated in the receiving groove, the two positioning columns are respectively plugged into and matched with the corresponding card holes, and the groove wall of the receiving groove abuts against the two second adjustment plates 1223.

[0057] With such a configuration, workers can adjust the spacing between the two hook assemblies 20 on the second lifting chain 121 by adjusting the detachable connection between the fixing piece 1225 and the different second adjustment parts 1224 of the two second adjustment plates 1223, so that the lifting device 100 of the present application can be suitable for battery modules with different widths.

[0058] The above description is only an optional embodiment of the present application, and does not limit the patent scope of the present application. All equivalent structural transformations made by using the contents of the present application specification and drawings under the inventive concept of the present application, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present application.
