[0038] Embodiment 1

[0039] A battery module lifting device comprises a lifting device seat 1, a hook unit 2 arranged at the end of the lifting device seat 1, and a supporting unit 3 arranged in the middle of the lifting device seat 1; the supporting unit 3 comprises a supporting piece 301 which can be replaced according to the size of the battery module to be lifted.

[0040] Based on the above structural design ideas, such as Figure 1 , Figure 2 and Figure 3 As shown, the battery module lifting device of this embodiment is provided with structures for lifting the battery module at the ends and the middle of the lifting device seat 1, so as to reduce the bending deformation caused by the gravity of the battery module after lifting, wherein the lifting unit 3 is for the more flexible part of the middle end plate of the battery module (such as Fig.10 As shown in the figure, it can play a supporting role, effectively preventing the module from falling and deforming in the middle, and has a good effect on improving the stability of battery module transportation; the supporting unit 3 can be adapted to different supporting parts 301 according to the size of the hoisted battery module, and a simple change of type can be performed to switch between different modes of hoisting double-row modules and single-row modules.

[0041] The operating procedure of the battery module lifting device of this embodiment is: when lifting and transporting a double-row module, first install the lifting support 301 adapted to the double-row module on the lifting unit 3 to complete the replacement of the double-row module lifting device; then use the hooks 201 of the hook units 2 at both ends of the lifting device to hook the end plates at both ends of the double-row module, and use the lifting hooks 3011 on the lifting support 301 to hook the middle end plate of the module to complete the module lifting and fixing; then the module can be transported to the battery pack shell by carrying the lifting device. Similarly, when hoisting and transporting a single-row module, first install the support member 301 adapted to the single-row module on the support unit 3 to complete the transformation of the single-row module hoisting device; then use the hooks 201 of the hook units 2 at both ends of the hoisting device to hook the end plates at both ends of the single-row module, and use the support hooks 3011 on the support member 301 to hook the middle end plate of the module to complete the module hoisting and fixing; then the module can be transported to the battery pack shell by carrying the hoisting device. Through the above hoisting device structure of this embodiment, the compatibility of the battery module hoisting device with battery modules of different sizes can be achieved.

[0042] A preferred implementation structure of this embodiment is that the spacing between the hook units 2 at both ends of the sling seat 1 can be adjusted to adapt to the lifting of battery modules of different lengths. Figure 4 and Figure 5As shown, the spacing between the hook units 2 at both ends of the hanger seat 1 is adjusted by sliding. For example, in this embodiment, four guide rails 102 along the length direction of the battery module can be set on the hanger seat 1, and each hook unit 2 is provided with two slide grooves that cooperate with the guide rails 102. When the module end plate is fixed to the hook 201 of the hook unit 2, the toggle clamps on the two hook units 2 simultaneously move in the opposite direction, driving the hook units 2 to move toward each other along the slide rails, so that the battery module is tightened by the two hook units 2, and at the same time, the hook 201 hooks the two end plates of the battery module to complete the hoisting and fixing of the end plates.

[0043] In addition, the spacing between the hooks 201 of the same hook unit 2 can be adjusted to adapt to the hoisting of battery modules of different widths. Specifically, the spacing between the hooks 201 of the same hook unit 2 can be adjusted in a disassembly manner, and each hook unit 2 is provided with a plurality of hook positioning holes 202, and the hooks 201 are fixed by bolts. In order to simply adapt to single-row and double-row modules, this embodiment is provided with four hook positioning holes 202. When hoisting a single-row module, the hook 201 can be installed on two adjacent hook positioning holes 202, such as the two middle positioning holes; when hoisting a double-row module, the hook 201 can be installed on two farther hook positioning holes 202, such as one or two positioning holes between the two hook positioning holes 202.

[0044] In a preferred embodiment, Figure 1 , Figure 6 , Figure 7 and Figure 8 As shown, the suspension unit 3 also includes a suspension bracket 302 fixedly connected to the suspension seat 1, and the suspension bracket 302 can be connected to the suspension member 301 adapted for the single-row and double-row modules through the suspension seat 303. When suspending a single-row module, only one suspension bracket 301 needs to be retained, and a single suspension hook 3011 on the suspension bracket 301 can support the middle end plate of the module. When suspending a double-row module, two suspension brackets 301 need to be retained, and the suspension hooks 3011 on the two suspension brackets 301 with opposite bending directions can support the middle end plate of the module. In addition, in this embodiment, the suspension bracket 301 can preferably be slid on the suspension bracket 302 by connecting the suspension seat 303, so that the disassembly and assembly of the suspension bracket 301 is simpler and the switching of different suspension modes is more efficient.

[0045] More preferably, the position of the suspension hook 3011 on the suspension member 301 can be adjusted and locked along the length direction of the battery module, so as to fine-tune the position of the suspension hook 3011 and adapt the contact position of the middle end plate of the battery module. Specifically, in this embodiment, a threaded fit is provided inside the suspension member 301, so that the suspension hook 3011 is matched with the adjustment knob 3012, and the position of the suspension hook 3011 is fine-tuned by rotating the adjustment knob 3012. After the position of the suspension hook 3011 is set, the locking knob 3013 is used to fix the position of the suspension hook 3011.

[0046] In addition, if Fig. 9 As shown, a lifting ring 101 may be further provided at the top of the lifting device seat 1, and the lifting ring 101 may be connected to an external power unit so as to move and transport the lifting device.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
