In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance. Among them, the terms "first position" and "second position" are two different positions.

[0035] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection or a detachable connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the protection scope of the utility model.

[0037] Combine the following Figures 1 to 5 The battery module lifting device provided by the utility model is introduced with reference to a specific embodiment. For the sake of convenience, it is referred to as the "lifting device" below. The lifting device is suitable for the battery pack assembly process, and includes a lifting plate 1 and a hook assembly 2. Along the length direction of the battery module (i.e., along the direction of battery cell stacking), a hook assembly 2 is installed on each of the opposite sides of the lifting plate 1. The hook assembly 2 is a conventional structure in the existing field of battery pack lifting and assembly technology, and this embodiment will not be described in detail here. When the lifting device is in use, each hook assembly 2 is connected to one of the end plates of the battery module, and then the battery module is lifted and transported to the battery box, and then moved to the starting position, thereby completing the lifting process of a battery module.

[0038] However, when hoisting a large and long battery module, the battery module as a whole may be deformed, presenting a "boat" shape with high sides near the end plate and low in the middle. To avoid the above phenomenon, the battery module is connected along the length direction. Figure 1 , Figure 2As shown, a plurality of support members 3 are arranged on the lifting plate 1 provided in this embodiment, and the plurality of support members 3 have the same horizontal height, and the plurality of support members 3 are located in the middle position of the battery module, so that the middle part of the battery module is supported by the plurality of support members 3 at the same horizontal height to prevent the battery module from sinking and deforming, thereby ensuring the stability of the battery module during lifting and transportation, ensuring the safety of lifting, and effectively improving the assembly efficiency of the battery pack.

[0039] Specifically, in the present embodiment, the support member 3 includes a vacuum pump, a pipe fitting and a suction cup 31. Among them, the surface of the suction cup 31 is fitted and connected to the top cover of the battery module, and the suction cup 31 is connected to the vacuum pump through the pipe fitting. Before lifting the battery module, the suction cup 31 is first placed above the battery module, and then the vacuum pump is started so that the surface of the suction cup 31 is tightly fitted and adsorbed on the top cover of the battery module, and then the hook assembly 2 can be manually hooked into the bolt holes on both sides of the end plate of the battery module, and the lifting can be performed normally after the connection is stable. Since the suction cup 31 has a strong adsorption capacity, it can ensure a good connection stability between the support member 3 and the battery module, ensure the hoisting stability, and it is relatively simple to use, and a stable connection can be achieved without a complex structure, which helps to simplify the structure of the entire hoisting device.

[0040] In this embodiment, Figure 3 As shown, twelve support members 3 are arranged on the lifting plate 1, and along the length direction of the battery module, the twelve support members 3 are staggered and evenly arranged on the lifting plate 1, so as to provide more uniform support in the length direction of the battery module and ensure that the force on the entire battery module is more evenly balanced.

[0041] It is understandable that the number of support members 3 arranged on the hanging plate 1 is determined according to the actual length of the battery module. As long as the force on the battery module can be ensured to be uniform and balanced, it is within the protection scope of the present utility model.

[0042] Optionally, a waist-shaped hole is opened on the lifting plate 1, and the suction cup 31 can be slidably arranged in the waist-shaped hole along the length direction of the waist-shaped hole, so that the adsorption position of the suction cup 31 can be slightly adjusted, thereby improving the accuracy of the adsorption position of the suction cup 31 and ensuring that multiple support members 3 can evenly support the battery module.

[0043] In this embodiment, Figure 4As shown, the hanging plate 1 includes a main board 11, and a hook assembly 2 is installed at each end of the main board 11 along the length direction of the battery module; in addition, the waist-shaped hole includes a first waist-shaped hole 1011, and twelve first waist-shaped holes 1011 are opened on the main board 11, which are respectively arranged in a one-to-one correspondence with the suction cup 31. The length direction of the first waist-shaped hole 1011 is parallel to the length direction of the battery module, and the suction cup 31 can be slidably arranged in the first waist-shaped hole 1011 along the length direction of the first waist-shaped hole 1011. Through the above arrangement, the suction cup 31 can adjust the adsorption position along the length direction of the battery module to ensure the accurate positioning of the suction cup 31.

[0044] More specifically, the hanging plate 1 also includes a slider 12, which is mounted on the main board 11. In this embodiment, the number of the sliders 12 is twelve, and the number of the sliders 12 corresponds to the number of the first waist-shaped holes 1011. In addition, the waist-shaped holes also include a second waist-shaped hole 1012, the length direction of the second waist-shaped hole 1012 is horizontally perpendicular to the direction of the first waist-shaped hole 1011, that is, the length direction of the second waist-shaped hole 1012 is parallel to the width direction of the battery module, and each slider 12 is provided with a second waist-shaped hole 1012, the second waist-shaped hole 1012 is arranged opposite to the first waist-shaped hole 1011, and the suction cup 31 is penetrated through the first waist-shaped hole 1011 and the second waist-shaped hole 1012, and can be slidably arranged in the second waist-shaped hole 1012 along the length direction of the second waist-shaped hole 1012. In this way, the suction cup 31 can adjust the adsorption position along two horizontal directions, that is, along the length direction of the battery module and along the width direction of the battery module, so as to further improve the effect of accurate positioning of the suction cup 31.

[0045] In order to improve the convenience and reliability of adjusting the suction cup 31, refer to Figure 5 As shown, in this embodiment, the support member 3 also includes a joint 32 and a fastening nut 33, wherein an air path is provided in the joint 32, and a threaded section is provided on the outer surface of the joint 32. The suction cup 31 is connected to the pipe fitting through the joint 32. After the joint 32 passes through the second waist-shaped hole 1012 and the first waist-shaped hole 1011, the threaded section on the joint 32 is threadedly connected to the fastening nut 33, and the lower surface of the fastening nut 33 is fitted and connected to the first waist-shaped hole 1011 or the second waist-shaped hole 1012 to fix the suction cup 31 and prevent the suction cup 31 from loosening and deflecting. The staff only needs to loosen the fastening nut 33 to adjust the adsorption position of the suction cup 31 in two horizontal directions, and then tighten the fastening nut 33 to complete the operation, which is simple, convenient, fast and efficient. In addition, after loosening the fastening nut 33, the horizontal height of the suction cup 31 can also be adjusted so that all the suction cups 31 can be kept at the same horizontal height, ensuring the stability and reliability of the adsorption of the suction cup 31.

[0046] In this embodiment, the fastening nut 33 is fitted against the second waist-shaped hole 1012 to enhance the connection stability between the slider 12 and the suction cup 31, and ensure that the suction cup 31 will not move with the slider 12 during the process of adjusting the adsorption position along the length direction of the battery module. In addition, in order to ensure the tightness of the connection between the slider 12 and the main board 11, the lifting device also includes an assembly part, and the slider 12 is fixedly connected to the main board 11 through the assembly part, so as to prevent the slider 12 from moving relative to the main board 11, and ensure the accuracy of the adsorption position of the suction cup 31.

[0047] Exemplarily, the assembly parts include assembly bolts and assembly nuts; a third waist-shaped hole 111 is formed through the main board 11, and a round hole 121 is formed through the slider 12. The round hole 121 is arranged relative to the third waist-shaped hole 111, and the length direction of the third waist-shaped hole 111 is parallel to the length direction of the battery module. After the assembly bolts pass through the third waist-shaped hole 111 and the round hole 121, they are threadedly connected to the assembly nuts. Through the above-mentioned assembly parts, the connection between the slider 12 and the main board 11 can be made stable, and by loosening the assembly nut, the horizontal adsorption position of the suction cup 31 can be adjusted by moving the slider 12.

[0048] Of course, in other embodiments, the length direction of the third waist-shaped hole 111 can also be parallel to the width direction of the battery module, so that after the suction cup 31 adjusts the adsorption position along the width direction of the battery module, it is fixed on the main board 11 through the slider 12 and the assembly part. Therefore, the utility model does not limit the length direction of the third waist-shaped hole 111.

[0049] Preferably, in this embodiment, four third waist-shaped holes 111 are evenly opened around the first waist-shaped hole 1011, and correspondingly, four round holes 121 are opened on the slider 12, so that the slider 12 can be tightly connected to the mainboard 11 all around, greatly improving the connection stability between the two.

[0050] Optionally, a rib plate 13 is also provided on the main board 11, and the extension direction of the rib plate 13 is parallel to the length direction of the battery module. The rib plate 13 can enhance the structural strength of the main board 11 to prevent the main board 11 from bending and deforming during the lifting of the battery module by the lifting device, thereby ensuring the adsorption stability between the suction cup 31 and the battery module.
