[0075] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0076] A battery cell module is formed by stacking multiple battery cells. In order to protect the battery cells, an end plate with an insulating cover is generally installed at both ends of the stacked battery cells in the longitudinal direction. Then, the two end plates and several battery cells are bundled and fixed with steel strips or steel plates to form a battery cell module.

[0077] After processing, the battery cell modules need to be transported to the next process. Large and heavy battery cell modules are typically moved using lifting equipment such as gantry cranes. However, different battery cell modules vary in size, often requiring multiple different lifting equipment specifications, resulting in poor compatibility. Therefore, a multifunctional lifting equipment is needed to accommodate battery cell modules of varying sizes.

[0078] Therefore, the present application provides two embodiments of a multifunctional spreader, which are described in detail below:

[0079] Example 1

[0080] See also Figure 1 As shown, the multifunctional sling provided in the first embodiment of the present application includes a base frame 10, a lifting member 20 and two sets of first lifting mechanisms 30. The lower end of the lifting member 20 is connected to the base frame 10, and the upper end of the lifting member 20 is connected to the execution end of the lifting equipment; the two sets of first lifting mechanisms 30 are connected along the first direction ( Figure 1 The first set of first lifting mechanisms 30 is configured to pick up or release the first end of the battery cell module 40 in the first direction, and the second set of first lifting mechanisms 30 is configured to pick up or release the second end of the battery cell module 40 in the first direction.

[0081] It can be seen that the multifunctional lifting device proposed in the present application realizes the lifting of the battery cell module 40 through the cooperation of the base frame 10, the lifting parts 20, the two sets of first lifting mechanisms 30 and the lifting equipment; at the same time, the two sets of first lifting mechanisms 30 are installed on the base frame 10 with adjustable spacing. By adjusting the spacing between the two sets of first lifting mechanisms 30, it is possible to adapt to the lifting of battery cell modules 40 of different specifications, thereby improving the compatibility of the lifting device for the battery cell module 40 and greatly reducing the investment cost of the lifting device.

[0082] See also Figures 1 to 4 As shown in FIG. 1 , as an embodiment, each set of the first hanging mechanism 30 includes a movable seat 31, a plurality of first hooks 32 and a locking assembly 33. The movable seat 31 can be mounted on the bottom surface of the base frame 10 so as to slide back and forth along a first direction; the plurality of first hooks 32 can slide back and forth along a second direction ( Figure 1 The first hooks 32 are installed on the movable seat 31 at intervals (in the Y direction in the second direction), and a plurality of first openings 41 are opened on the end plate of the battery cell module 40. Each first hook 32 corresponds to a first opening 41. Each first hook 32 can be inserted into or pulled out from the corresponding first opening 41. The second direction is perpendicular to the first direction; the locking assembly 33 is configured to fix or loosen the movable seat 31 relative to the base frame 10.

[0083] Specifically, a guide assembly is provided between the movable seat 31 and the base frame 10, and the guide assembly includes two linear guide rails 34 and a plurality of sliders 35. The two linear guide rails 34 are fixedly installed in parallel on the bottom surface of the base frame 10 and both extend along the first direction.

[0084] Specifically, the locking assembly 33 includes a locking plate 330 and a locking screw 331. The locking plate 330 is fixedly mounted on the bottom surface of the base 10 and extends along the first direction. The locking plate 330 is provided with first threaded holes at intervals along the first direction. A number of through holes are provided on the movable seat 31 to match the first threaded holes. The locking screw 331 passes through the through hole on the movable seat 31 and is locked in the corresponding first threaded hole on the locking plate 330 to fix the movable seat 31 relative to the base 10; loosen the locking screw 331 and remove the locking screw 331 from the first threaded hole to loosen the movable seat 31 relative to the base 10, and then adjust the position of the movable seat 31 along the first direction. The overall structure of the locking assembly 33 is simple, easy to implement, and low in cost.

[0085] It can be seen that through the cooperation of the movable seat 31, the base frame 10 and the locking assembly 33, the movable seat 31 is fixed or loosened relative to the base frame 10, and after the movable seat 31 is loosened relative to the base frame 10, the position of the movable seat 31 on the base frame 10 along the first direction is adjusted, thereby realizing the adjustment of the first hanging mechanism 30 in the first direction, and then adjusting the distance between the two sets of first hanging mechanisms 30; at the same time, through the cooperation of the first hook 32 and the first opening 41, a method for picking up the battery cell module 40 with a simple structure, easy operation, stable and reliable connection is provided.

[0086] As an embodiment, each set of first hanging mechanisms 30 further includes at least two support members 36 , the upper end of each support member 36 can be mounted on the movable seat 31 so as to be adjustable in position along the second direction, and a first hook 32 is mounted on the lower end of each support member 36 .

Each group of second threaded holes 310 includes a plurality of second threaded holes 310 spaced apart along the second direction. The fixing screw passes through the fixing hole 360 ​​and is locked in the corresponding second threaded hole 310 to fix the support member 36 on the movable seat 31; by fixing the support member 36 in the second threaded hole 310 at different positions, the installation position of the support member 36 in the second direction can be adjusted.

[0089] It can be seen that by setting at least two support members 36 and installing the upper end of the support member 36 on the movable seat 31 so that it can be adjusted along the second direction, the adjustment of the distance between two adjacent first hooks 32 is achieved to adapt to the lifting of battery cell modules 40 with different first opening 41 spacings, thereby further improving the compatibility of the lifting equipment.

[0103] As an embodiment, an elastic reset member 5119 is installed on each lifting member 5111, and the first end of the elastic reset member 5119 is connected to the position of the lifting member 5111 above the waist-shaped hole 5116, and the second end of the elastic reset member 5119 is connected to the rotating shaft 5113. The elastic reset members 5119 on the two lifting members 5111 are configured to keep the first support rod 521 in the first position or the second position; when the first support rod 521 is in the first position, the shift rod 510 and the first connecting rod 5112 are located outside the side of the lifting member 5111 close to the battery cell module 40; when the first support rod 521 is in the second position, the shift rod 510 and the first connecting rod 5112 are located outside the side of the lifting member 5111 away from the battery cell module 40.

[0104] Specifically, the elastic reset member 5119 is a coil spring.

[0105] It can be seen that by installing an elastic return member 5119 on each lifting member 5111 and hingedly connecting the two ends of the elastic return member 5119 to the corresponding lifting member 5111 and the rotating shaft 5113 respectively, the first support rod 521 is maintained in the first position or the second position, which is beneficial to improving the stability and reliability of the support mechanism 52.

[0106] The specific working principle of the bottom support mechanism 50 proposed in the embodiment of the present application is as follows:

[0107] In the initial state, the first supporting rod 521 is in the second position, and the shifting rod 510 and the first connecting rod 5112 are located outside the lifting member 5111 on a side away from the battery module 40;

[0108] The shifting rod 510 is pushed to move close to the battery module 40. The shifting rod 510 drives the swinging member 520 to install one end of the first support rod 521 through the first connecting rod 5112, the rotating shaft 5113, the rotating member 5114 and the second connecting rod 5118 to move close to the battery module 40 to the first position, so that the first support rod 521 supports the bottom surface of the battery module 40 picked up by the two sets of first lifting mechanisms 30 on the side extending along the first direction and the second support rod 522 rests on the side of the battery module 40 extending along the first direction.

[0109] As an embodiment, a storage box 60 is installed on the mounting frame 5110, and hooks corresponding to battery cell modules 40 of different specifications are stored in the storage box 60, which is convenient for replacing and storing the hooks.

[0110] As an embodiment, the base frame 10 is provided with limiting brackets 70 on both sides of the opposite sides in the second direction. The limiting brackets 70 are configured to support the shift rod 510 so that when the bottom support mechanism 50 is not in use, the shift rod 510 is clamped on the corresponding limiting bracket 70 to keep the bottom support mechanism 50 fixed.

[0111] See also Figure 1 、 Figure 8 and Figure 9 As shown, as an embodiment, the multifunctional sling also includes several sets of second lifting mechanisms 80, each set of second lifting mechanisms 80 includes a traction member 81 and a second hook 82, the upper end of the traction member 81 is connected to the base frame 10, and the lower end of the traction member 81 is provided with a second hook 82, and the second hook 82 is configured to pick up or release the base 42 of the battery cell module 40.

[0112] Specifically, a plurality of second openings 420 are defined on the base 42 of the battery module 40 . Each second hook 82 corresponds to one second opening 420 . Each second hook 82 can be inserted into or removed from the corresponding second opening 420 .

[0113] It can be seen that by setting up several sets of second lifting mechanisms 80, the base 42 of the battery cell module 40 can be lifted. In conjunction with two sets of first lifting mechanisms 30, the battery cell module 40 and the base 42 of the battery cell module 40 can be lifted at the same time, or the base 42 of the battery cell module 40 can be lifted alone, thereby improving the compatibility of the lifting equipment.

[0114] The multifunctional spreader proposed in this application has the following advantages:

[0115] 1) It can be adapted to lift battery modules of different specifications, improving the compatibility of the lifting equipment for battery modules and greatly reducing the investment cost of the lifting equipment;

[0116] 2) A bottom support mechanism is provided to prevent the battery module from accidentally falling, greatly improving the safety and reliability of the multi-functional lifting device;

[0117] 3) The bottom support mechanism adopts connecting rod transmission, which has a simple overall structure, low cost and stable and reliable operation;

[0118] 4) By providing the first lifting mechanism and the second lifting mechanism, it is possible to lift the base of the cell module and to lift the cell module and the base of the cell module simultaneously, thereby further improving the compatibility of the lifting device.

[0119] Example 2

[0120] It should be noted that the structures of the second embodiment are substantially the same as those of the first embodiment, and only the differences between the two embodiments are described below.

[0121] See also Figure 10 As shown, the main differences between the second embodiment and the first embodiment are:

[0122] As an embodiment, each set of the first lifting mechanism 30 of the multifunctional sling of Example 2 of the present application includes four support members 36, the upper end of each support member 36 can be installed on the movable seat 31 so as to adjust the position along the second direction, and a first hook 32 is installed at the lower end of each support member 36.

[0123] It can be seen that by providing four support members 36 and installing a first hook 32 at the lower end of each support member 36 , the lifting of large battery cell modules is achieved, further improving the compatibility of the first lifting mechanism 30 .

[0124] As an implementation manner, the two sets of bottom-supporting mechanisms 50 of the multifunctional sling of Example 2 of the present application are configured to be able to approach or move away from each other along the second direction on the base frame 10.

[0125] Specifically, the mounting bracket 5110 can be arranged along the second direction ( Figure 10 The bottom supporting mechanisms 50 are adjustably mounted on the base frame 10 in the middle Y direction) so that the two sets of bottom supporting mechanisms 50 can approach or move away from each other along the second direction on the base frame 10, thereby adjusting the spacing between the two sets of bottom supporting mechanisms 50.

[0126] Specifically, a guide pair consisting of a linear guide rail 34 and a slider 35 is arranged between the mounting frame 5110 and the base frame 10. The linear guide rail 34 is installed on the top surface of the base frame 10 and extends along the second direction. The slider 35 is fixed on the mounting frame 5110 and can be slidably assembled on the linear guide rail 34 to ensure the stability of the mounting frame 5110 in moving relative to the base frame 10.

[0127] It can be seen that by arranging the two sets of bottom supporting mechanisms 50 to be able to move closer to or farther away from each other along the second direction on the base frame 10, the spacing between the two sets of bottom supporting mechanisms 50 in the second direction can be adjusted to adapt to battery modules of different specifications.

[0128] As an embodiment, a balancing member 53 is provided on each mounting frame 5110 of the multifunctional sling of Example 2 of the present application, the first end of the balancing member 53 is connected to the mounting frame 5110, and the second end of the balancing member 53 is connected to the lifting member 5111, and the balancing member 53 is configured to pull the lifting member 5111 upward through elastic force.

[0129] Specifically, the balancing member 53 includes two spring balancers 530 symmetrically arranged on both sides of the lifting member 5111. The fixed end of each spring balancer 530 is assembled on the mounting frame 5110, and the movable end of each spring balancer 530 is connected to the lifting member 5111. The two spring balancers 530 provide an upward pulling force to the lifting member 5111, so that the lifting member 5111 is in a weightless state.

[0130] It can be seen that by arranging a balancing member 53 on each mounting frame 5110, the balancing member 53 pulls the lifting member 5111 upward through elastic force, which facilitates manual operation of the bottom supporting mechanism 50 and saves manpower.

[0131] See also Figures 9 to 11 As shown, as an embodiment, the second hook 82 of the multifunctional sling of Example 2 of the present application includes a base 820 and a hook body 821, and the hook body 821 is rotatably mounted on the base 80 so that the hook body 821 can be switched to an unlocked state or a locked state; when the hook body 821 is switched to the unlocked state, the hook body 821 can be inserted into the corresponding second opening 420 or pulled out from the corresponding second opening 420; when the hook body 821 is switched to the locked state, the hook body 821 is locked in the second opening 420 to prevent it from falling off.

[0132] Specifically, the second opening 420 extends in the vertical direction, the hook body 821 matches the second opening 420, and a handle 822 is provided on the hook body 821. The hook body 821 can be rotated relative to the base 820 to a vertical state (i.e., an unlocked state) or a horizontal state (i.e., a locked state) by the handle 822. When the hook body 821 hooks the base 42 of the battery module, the hook body 821 is first rotated to the vertical state. At this time, the hook body 821 can be smoothly inserted into the corresponding second opening 420. After the hook body 821 is inserted into the corresponding second opening 420, the hook body 821 is rotated to the horizontal state. At this time, there is interference between the hook body 821 and the base 42 in the horizontal direction, and the hook body 821 is locked in the second opening 420 to prevent it from falling off; when the hook body 821 is removed from the base 42 of the battery module, the hook body 821 is first rotated to the vertical state, and then the hook body 821 can be pulled out from the corresponding second opening 420.

[0133] Specifically, when the hook body 821 is in a vertical state, the hook body 821 can be inserted into the second opening 420 . When the hook body 821 is in a horizontal state, the longer end of the hook body 821 prevents the hook body 821 from being separated from the second opening 420 .

[0134] It can be seen that by rotatably mounting the hook body 821 on the base 820 , the hook body 821 is locked in the second opening 420 to prevent it from falling off, thereby preventing the hook body 821 of the second hook 82 from falling off from the second opening 420 when the base 42 is lifted, thereby improving the safety of the second lifting mechanism 80.

Various changes and modifications may be made to the present application without departing from the spirit and scope of the present application.
