[0042] As described in the background technology, the battery pack module is provided with lifting holes to provide lifting points during the process of lifting the battery pack module. These lifting holes are often not centered, and the module cannot be kept horizontal during lifting. In addition, the positions of the lifting holes on different battery pack modules are uncertain, and the existing lifting tools cannot be used for a variety of battery pack modules.

[0043] In view of this, the embodiment of the utility model provides a single-hole hanger 10 and a battery pack module hoisting device, wherein the single-hole hanger 10 includes a main bracket 11, a hook assembly 12, and a positioning assembly 13. The single-hole hanger 10 can keep the battery pack module in a horizontal state through the interference of the positioning assembly 13, and can be adapted to a variety of battery pack modules by moving the hook assembly 12 in the slot 112.

[0044] The following is an exemplary description of the single-hole hanger 10 provided in the embodiment of the utility model:

[0045] See also Figure 1 , Figure 1 A structural schematic diagram of a single-hole hanger 10 provided for an embodiment of the utility model, the single-hole hanger 10 includes a main support 11, a hook assembly 12 and a positioning assembly 13, the main support 11 includes a hanging hole 111, a slot 112 and a plug-in hole 113; the hanging hole 111 is opened on the central axis of the main support 11, the slot 112 is opened horizontally below the hanging hole 111, the positioning assembly 13 is installed in the plug-in hole 113 with a fixing member 14, the hook assembly 12 includes a hook fixing pin 121, a hook shaft 122 and a hook 123; the hook fixing pin 121 is movably installed in the slot 112, the hook fixing pin 121 can slide in the slot 112, the hook 123 is connected to the hook fixing pin 121 through the hook shaft 122, and the hook 123 can rotate along the hook shaft 122.

[0046] See also Figure 2 , Figure 2 A schematic diagram of hoisting a battery pack module is provided for an embodiment of the utility model. When the battery pack module needs to be hoisted, the single-hole hoist 10 is moved to the upper part of the battery pack module that needs to be hoisted, and the positioning assembly 13 is aligned with the positioning pin hole position of the battery pack module and pressed down. When the positioning pin 132 of the single-hole hoist 10 is pressed to the bottom, the hook 123 is hung in the end plate hoisting hole 111 of the battery pack module. The same method is used to install two single-hole hoists 10 into the positioning pin holes of the battery pack module to complete the hoisting. When the battery pack module is hoisted, although the end plate hoisting hole 111 of the battery pack module is not centered, the hoisting hole 111 on the single-hole hoist 10 is designed in the middle position. After lifting, the battery pack module is kept in a horizontal state by the interference of the positioning assembly 13 with the positioning pin hole of the battery pack module.

[0047] See also Figure 2 as well asFigure 3 , Figure 3 is another lifting schematic diagram of a battery pack module provided by an embodiment of the present utility model. Figure 2 In Figure 3 , all the end plate lifting holes 111 of the battery pack module are on the right side. When the battery pack module is as

[0048] shown, one end plate lifting hole 111 is on the left side and one is on the right side. At this time, after the hook fixing pin 121 is rotated and slides from one end of the slot hole 112 of the main bracket 11 to the other end, the single-hole lifting tool 10 is inserted into the end plate positioning pin hole and the end plate lifting hole 111 of the battery pack module in the above-mentioned manner to complete the lifting. Through this method, it can be applicable to a variety of battery pack modules.

[0049] In a possible implementation manner, in order to make the hook 123 more stable when hooking the end plate positioning pin hole of the battery pack module, the hook 123 can be designed as an S-shaped mechanism. Specifically, please refer to Figure 4 , Figure 4 which is a structural schematic diagram of a hook 123 provided by an embodiment of the present utility model. The hook 123 can include a first connecting portion 1231, a main bracket contact portion 1232, and a hook portion 1233. The first connecting portion 1231 is provided with a first through hole 1234. The hook shaft 122 passes through the first through hole 1234 to connect the hook fixing pin 121 with the hook 123. The main bracket contact portion 1232 can contact the main bracket 11 for limiting, and is used to fix the hook 123 when lifting the battery pack module. The hook portion 1233 is used to be hung into the end plate lifting hole 111 of the battery pack module when lifting the battery pack module.

[0050] As Figure 4 can be seen, the first connecting portion 1231 of the hook 123 is provided with a first through hole 1234, and is connected with the hook fixing pin 121 through this first through hole 1234. Therefore, the hook 123 can rotate along with the hook shaft 122. When lifting, the hook 123 is in a vertical state, and the main bracket contact portion 1232 contacts the main bracket 11 to form a limiting effect, which can make the battery pack module more stable when being lifted.

[0051] Furthermore, the hook portion 1233 is a right-angle hook. When the hook portion 1233 is hung into the end plate lifting hole 111 of the battery pack module, the bottom end of the hook portion 1233 can well support the end plate lifting hole 111 of the battery pack module, and both ends of the hook portion 1233 can contact and limit the end plate above the end plate lifting hole 111, finally making the lifted battery pack module not easy to shake.

[0052] In a possible implementation, in order to make the hook assembly 12 easier to move and still be stable, please refer to Figure 5 , Figure 5 FIG. is a schematic structural view of a hook fixing pin 121 provided by an embodiment of the present invention. The hook fixing pin 121 may include a second connecting portion 1221 and a fixing portion 1222. An installation groove 1224 and two installation holes 1223 are provided on the second connecting portion 1221. The two installation holes 1223 are distributed on opposite two groove side walls of the installation groove 1224. Both of the two installation holes 1223 communicate with the installation groove 1224. A hook shaft 122 passes through the two installation holes 1223 to connect the hook fixing pin 121 with the hook 123.

[0053] Preferably, the installation groove 1224 of the second connecting portion 1221 can just fit into the first connecting portion 1231 of the hook 123. The hook shaft 122 passes through the two installation holes 1223 of the second connecting portion 1221 and the first through hole 1234 of the first connecting portion 1231 to connect the second connecting portion 1221 and the first connecting portion 1231. C-shaped circlips can be used to fix both ends of the hook shaft 122.

[0054] Preferably, the fixing portion 1222 is of a waist-shaped structure. Both ends of the slot hole 112 are round holes, and the diameter of the round holes is greater than the width of the middle portion of the slot hole 112. When the fixing portion 1222 is in the round holes and the hook 123 hangs down, the fixing portion 1222 can be locked in the round holes. When the hook 123 is horizontal, the fixing portion 1222 can slide in the slot hole 112.

[0055] Continue to refer to Figure 5 , the fixing portion 1222 is of a waist-shaped structure and includes a wide surface and a narrow surface. When hoisting, the fixing portion 1222 is perpendicular to the slot hole 112 at both ends of the fixing portion 1222, and the wide surface of the fixing portion 1222 is perpendicular to the slot hole 112 of the main bracket 11. Since both ends of the slot hole 112 are round holes and the diameter of the round holes is greater than the width of the middle portion of the slot hole 112, when the wide surface of the fixing portion 1222 is perpendicular to the slot hole 112 of the main bracket 11, the wide surface of the fixing portion 1222 cannot pass through the middle portion of the slot hole 112 and can just be stuck at both ends of the slot hole 112. Please refer to Figure 6 , Figure 6 FIG. is a schematic view of the movement of a hook assembly 12 provided by an embodiment of the present invention. The fixing portion 1222 of the hook fixing pin 121 is of a waist-shaped structure and is rotated 90 degrees to facilitate left and right sliding in the slot hole 112 of the main bracket 11 and can be locked when it falls into the round holes at both ends and the hook 123 hangs down, so that the hook fixing pin 121 can move easily in the slot hole 112 and still be stable during hoisting.

[0056] In a possible implementation, in order to keep the hook 123 from falling off easily when hanging into the end plate lifting hole 111 of the battery pack module, please refer to Figure 7, Figure 7 It is a schematic structural diagram of a positioning component 13 provided by an embodiment of the present invention. The positioning component 13 may include a positioning pin 132 and a spring 131, and the spring 131 is sleeved on the surface of the positioning pin 132. The positioning component 13 includes a positioning pin 132 and a spring 131, and the spring 131 is sleeved on the surface of the positioning pin 132.

[0057] When hoisting the battery pack module, when the positioning pin 132 is pressed to the bottom, the positioning pin 132 is aligned with the positioning pin hole of the battery pack module and pressed down. When the positioning pin 132 of the single-hole hoist 10 is pressed to the bottom, the hook 123 is hung into the end plate lifting hole 111 of the battery pack module. At this time, when the spring 131 of the single-hole hoist 10 is released, it rebounds, forming a force exerted by the spring 131 downward on the battery pack module. The hook 123 hooks the end of the battery pack module, forming an upward force exerted on the battery pack module. The two upward and downward forces formed can well keep the hook 123 from falling off when hanging into the end plate lifting hole 111.

[0058] Optionally, the fixing member 14 is an M4 set screw, and a plurality of M4 set screws fix the positioning pin 132 and the spring 131 in the jack 113.

[0059] It is a mechanical fastener with a specification of M4, that is, a threaded fastener with a diameter of 4 mm, a threaded rod for fixing or adjusting the position, which can achieve the effect of tightening or loosening by rotation. The M4 set screw has a self-locking function and can prevent self-loosening to a certain extent due to vibration or impact.

[0060] Preferably, the end of the positioning pin 132 is spherical. The spherical end can provide multi-directional alignment freedom, and when hoisting, the positioning pin 132 can be very conveniently inserted into the positioning pin hole of the battery pack module.

[0061] Based on the above implementation, an embodiment of the present invention also provides a battery pack module hoisting device, including two single-hole hoists 10 and a connecting rod. The connecting rod connects the two single-hole hoists 10 through the lifting holes 111 of the two single-hole hoists.

[0062] In summary, for a single-hole hoist and a battery pack module hoisting device provided by an embodiment of the present invention, the single-hole hoist inserts the positioning component into the end plate positioning pin hole of the battery pack module, and the lifting hole is designed in the middle position, which can keep the battery pack module in a horizontal state. Through the movement of the hook component in the slot hole of the main bracket, it can be applicable to a variety of battery pack modules, and the waist-shaped structure of the fixing part of the hook fixing pin can make the hook fixing pin move easily in the slot hole and still be stable during hoisting. And through the spring design of the positioning component, it can well keep the hook from falling off when hanging into the end plate lifting hole.
