Technical Field
[0001] This application relates to the technical field of battery production and manufacturing, and in particular, to a module hoisting device. Background Art
[0002] During the production process of a battery pack, it is necessary to install battery modules into a battery box. Since the battery modules are heavy, manual handling is inconvenient and there are safety hazards. Therefore, currently, the installation of battery modules into the box is usually completed with the assistance of a hoisting device.
[0003] Existing hoisting devices generally have hooks provided at both ends of a hanging beam to connect the battery modules through the hooks at both ends. However, the hooks are usually exposed, which causes the hooks to easily collide with the battery modules and be damaged or cause a short-circuit accident. Utility Model Content
[0004] The purpose of this utility model is to provide a module hoisting device to prevent the hooks from colliding with the battery modules and being damaged or causing a short circuit in the battery modules.

The hoisting tool assembly includes a positioning member and a hook. The hook is hung on the hanging beam through the positioning member.
[0006] The hook is movable. A receiving space is provided at a position of the positioning member opposite to the hook. The hook can be completely received in the receiving space, or the hook can extend toward the battery module below the hanging beam to be connected to the battery module.
[0007] Furthermore, the positioning member is slidably connected to the hanging beam in the first direction, so that the battery module can extend into and be limited between the positioning members of the two hoisting tool assemblies.
[0008] Furthermore, the positioning member is a positioning plate. The thickness direction of the positioning plate is along the first direction. A hollow hole penetrating the positioning plate in the first direction is provided on the positioning plate to form the receiving space.
[0009] Furthermore, the thickness of the positioning plate is d, and 3 mm ≤ d ≤ 15 mm.
[0010] Furthermore, the hoisting tool assembly further includes a connecting rod;
[0011] The connecting rod is rotatably mounted on the positioning member about its own axis. The axis direction of the connecting rod is perpendicular to the first direction;
[0012] One end of the connecting rod extends into the accommodating space and is connected to one end of the hook, so as to drive the hook to screw into or out of the accommodating space.
[0013] Further, one end of the positioning member is slidably connected to the suspension beam through a sliding plate, and a indexing pin is provided on the sliding plate;
[0014] The sling assembly further includes a stop member, the stop member is fixed on the suspension beam, and the stop member is provided with a stop hole for the indexing pin to insert.
[0015] Further, a collision avoidance pad is provided below the suspension beam, and the suspension beam abuts against the top of the battery module through the collision avoidance pad.
[0016] Further, collision avoidance pads are provided on both sides of the suspension beam in the second direction, and the second direction is perpendicular to the first direction;
[0017] The collision avoidance pad includes a flat pad portion and a limiting portion connected to each other. The collision avoidance pad abuts against the top of the battery module through the flat pad portion, and the collision avoidance pad abuts against the side portion of the battery module in the second direction through the limiting portion.
[0018] Further, the thickness of the flat pad portion is h, and 5mm ≤ h ≤ 30mm.
[0019] Further, an end plate is provided at the end of the battery module opposite to the positioning member. A slot hole is provided on one side of the end plate facing the positioning member. A module fixing hole penetrating the end plate in the vertical direction is provided on the end plate, and the module fixing hole passes through the slot hole;
[0020] The free end of the hook can extend into the slot hole and abut against the top wall of the slot hole. A positioning protrusion is provided on the top of the free end of the hook, and the positioning protrusion extends into the module fixing hole.
[0021] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0022] The module hoisting device provided by the present utility model includes a suspension beam and a sling assembly. Sling assemblies are provided at both ends of the suspension beam in the first direction. The suspension beam can connect a hoisting device and is connected to a battery module through the sling assemblies at both ends, so as to hoist the battery module by relying on the hoisting device and hoist the battery module into a box. The sling assembly includes a positioning member and a hook. The hook is installed on the positioning member and is hung below the suspension beam through the positioning member to connect the battery module when hoisting the battery module. Among them, an accommodating space is provided at the position where the positioning member installs the hook, and the hook is movable relative to the positioning member, so that the hook can protrude from the positioning member or retract into the accommodating space of the positioning member.
[0023] When the hook protrudes from the positioning member, the hook extends towards the battery module so that the hook can be connected to the battery module to lift the battery module; when the hook retracts into the accommodation space of the positioning member, the accommodation space completely houses the hook, so that the hook does not protrude from the outer surface of the positioning member. Thus, when the battery module is lifted into the box, the hook can be retracted into the positioning member to release the battery module, and then the lifting beam can be lifted to make the hook withdraw from the inside of the battery box and between two adjacent battery modules. Moreover, the hook is housed inside the positioning member during the process of withdrawing from the battery box, which can effectively prevent the hook from colliding with the adjacent battery module and being damaged or causing a short circuit accident to the battery module.

[0036] Next, refer to Figures 1 to 3 Describe the module hoisting device according to some embodiments of the present application.
[0037] The present application provides a module hoisting device. As Figure 1 shown, the module hoisting device includes a lifting beam 1 and a sling assembly 2. Sling assemblies 2 are provided at both ends of the lifting beam 1 in the first direction a. The lifting beam 1 can be connected to a hoisting device and connected to a battery module 3 through the sling assemblies 2 at both ends, so as to hoist the battery module 3 by relying on the hoisting device and hoist the battery module 3 into a box.
[0038] As Figure 2 and Figure 3As shown, the sling assembly 2 includes a positioning member 21 and a hook 22. The hook 22 is installed on the positioning member 21 and is hung under the hanging beam 1 through the positioning member 21 to connect the battery module 3 when lifting the battery module 3. Among them, a receiving space 27 is provided at the position where the positioning member 21 installs the hook 22, and the hook 22 is movable relative to the positioning member 21, so that the hook 22 can protrude from the positioning member 21 or retract into the receiving space 27 of the positioning member 21.
[0039] When the hook 22 protrudes from the positioning member 21, the hook 22 extends towards the battery module 3, so that the hook 22 can be connected to the battery module 3 to lift the battery module 3; when the hook 22 retracts into the receiving space 27 of the positioning member 21, as Figure 3 shown, the receiving space 27 completely houses the hook 22, so that the hook 22 does not protrude from the outer surface of the positioning member 21. Thus, when the battery module 3 is lifted and loaded into the box, the hook 22 can be retracted into the positioning member 21 to release the battery module 3, and then lifting the hanging beam 1 can make the hook 22 withdraw from the inside of the battery box and between two adjacent battery modules 3. Moreover, the hook 22 is housed inside the positioning member 21 during the process of withdrawing from the battery box, which can effectively prevent the hook 22 from colliding with the adjacent battery module 3 and being damaged or causing a short-circuit accident of the battery module 3.
[0040] In this embodiment, preferably, as Figure 1 shown, when lifting the battery module 3, the battery module 3 can extend between the positioning members 21 at both ends of the hanging beam 1, so that the battery module 3 is clamped between the positioning members 21 at both ends of the hanging beam 1 to limit the relative position between the module lifting device and the battery module 3 in the first direction a, and the hook 22 on each positioning member 21 can be connected to the battery module 3 after protruding.
[0041] Preferably, as Figure 2 shown, each positioning member 21 is slidably connected to the hanging beam 1 along the first direction a, so that the distance between the positioning members 21 at both ends of the hanging beam 1 is adjustable. Thus, when the battery module 3 extends between the two positioning members 21, the distance between the two positioning members 21 can be adjusted to be larger to facilitate the battery module 3 to extend between the two positioning members 21, and then the distance between the two positioning members 21 is adjusted to be smaller, so that the two positioning members 21 respectively abut against the battery module 3 to clamp and limit the battery module 3.
[0042] In this embodiment, preferably, as Figure 2As shown, the sling assembly 2 further includes a stopper 26. The stopper 26 is fixed to the suspension beam 1, and the stopper 26 is provided with a stopper hole. One end of the positioning member 21 facing the suspension beam 1 is slidably connected to the suspension beam 1 along the first direction a through a slide plate 24, and a indexing pin 25 is provided on the slide plate 24. Moving the positioning member 21 can make the indexing pin 25 opposite to the stopper hole and insert into the stopper hole, so as to stop the positioning member 21 under the cooperation of the indexing pin 25 and the stopper hole. Therefore, when the battery module 3 needs to extend between the positioning members 21 at both ends of the suspension beam 1, the indexing pins 25 of the two positioning members 21 can be withdrawn from the corresponding stoppers 26 to move the two positioning members 21 and increase the distance between the two positioning members 21. After the battery module 3 enters between the two positioning members 21, move the two positioning members 21 again to make the indexing pins 25 of the two positioning members 21 respectively insert into the corresponding stoppers 26 to stop the two positioning members 21, so that the two positioning members 21 can stably limit and clamp the battery module 3.
[0043] In this embodiment, preferably, as Figure 2 shown, the positioning member 21 is a positioning plate. The thickness direction of the positioning plate is arranged along the first direction a, and the positioning plate is provided with a hollow hole penetrating the positioning plate along the first direction a to form a receiving space 27 for receiving the hook 22. When the hook 22 is completely received in the hollow hole, neither side of the hook 22 in the first direction a protrudes from the plate surface of the positioning plate.
[0044] Therefore, when hoisting the battery module 3 into the box, it is only necessary to ensure that the distance between two adjacent battery modules 3 connected along the first direction a in the battery box is greater than the thickness of the positioning plate, so as to reduce the distance between two adjacent battery modules 3 along the first direction a, reduce the size of the battery box in the first direction a, and improve the energy density of the battery pack.
[0045] In this embodiment, preferably, the thickness of the positioning plate is d, and 3mm ≤ d ≤ 15mm, so that while the positioning plate has a relatively thin thickness, the strength of the positioning plate can also be ensured to ensure the stability of hoisting the battery module 3.
[0046] In an embodiment of the present application, preferably, as Figure 2 shown, the sling assembly 2 further includes a connecting rod 23. The axis direction of the connecting rod 23 is perpendicular to the first direction a, and the connecting rod 23 is rotatably installed on the positioning member 21, so that the connecting rod 23 can rotate around its own axis. At the same time, one end of the connecting rod 23 extends into the receiving space 27 and is connected to one end of the hook 22. Therefore, by rotating the connecting rod 23, the free end of the hook 22 can be screwed out of the positioning member 21 to connect the battery module 3, or the free end of the hook 22 can be screwed into the positioning member 21 to release the battery module 3, and the hook 22 can be completely received through the receiving space 27 of the positioning member 21.
[0047] Specifically, a mounting hole is provided on the positioning member 21, and the axial direction of the mounting hole is arranged along the vertical direction. The upper end of the mounting hole passes through the positioning member 21, and the lower end of the mounting hole is first connected with the accommodating space 27; the connecting rod 23 is rotatably inserted into the mounting hole, the upper end of the connecting rod 23 extends out of the positioning member 21 and is provided with a handle portion, and the lower end of the connecting rod 23 extends into the accommodating space 27 and is connected to one end of the hook 22; the connecting rod 23 can be rotated by moving the handle portion at the upper end of the connecting rod 23, thereby driving the hook 22 to rotate, so that the hook 22 can be screwed in or out of the positioning member 21.
[0048] In this embodiment, preferably, Figure 1 As shown, both ends of the battery module 3 in the length direction are provided with end plates 31. When the battery module 3 is lifted, the length direction of the battery module 3 is also arranged along the first direction a, so that the end plates 31 at both ends of the battery module 3 are arranged in a one-to-one correspondence with the positioning members 21 at both ends of the suspension beam 1. For any opposite end plates 31 and positioning members 21, a slot is provided on the side of the end plate 31 facing the positioning member 21, and the end of the hook 22 connected to the connecting rod 23 is a fixed end, and the other end of the hook 22 is a free end. Rotating the hook 22 can make the free end of the hook 22 rotate out of the positioning member 21 and extend into the slot of the end plate 31, and by lifting the suspension beam 1, the top wall of the slot can be mounted on the hook 22, so that it can be lifted along with the suspension beam 1, thereby realizing the lifting of the battery module 3.
[0049] Preferably, the end plate 31 is provided with a module fixing hole penetrating the end plate 31 in the vertical direction, and the module fixing hole is used to penetrate a fastener, so that after the battery module 3 is hoisted into the box, the battery module 3 is fixed in the battery box by the fastener. Figure 3 As shown, a positioning protrusion 28 is provided on the top of the free end of the hook 22. When the free end of the hook 22 is inserted into the slot, the positioning protrusion 28 can be inserted into the module fixing hole, thereby realizing the positioning connection between the hook 22 and the battery module 3, improving the stability of lifting the battery module 3, and at the same time, the lifting of the module is realized by relying on the existing slots and module fixing holes of the end plate 31, without the need to set additional positioning holes, thereby improving the applicability of the module lifting equipment.
[0050] In this embodiment, preferably, Figure 1 and Figure 2 As shown, there is also a second direction b perpendicular to the first direction a in the horizontal direction, module positioning holes are provided on both sides of the second direction b of the end plate 31, and two hooks 22 are also provided on the positioning member 21 at intervals along the second direction b, and each positioning member 21 is connected to the battery module 3 through the two hooks 22, thereby providing stability for lifting the battery module 3.
[0051] In one embodiment of the present application, preferably, Figure 1 and Figure 2As shown in the figure, a collision prevention pad 11 is installed below the hanging beam 1 through a bracket. The collision prevention pad 11 is elastic. When the hanging beam 1 descends to pick up the battery module 3 to be lifted, the hanging beam 1 can abut against the top of the battery module 3 through the collision prevention pad 11, avoiding rigid contact between the hanging beam 1 and the battery module 3 and damaging the battery module 3.
[0052] Preferably, at least one collision prevention pad 11 is provided on both sides of the hanging beam 1 in the second direction b. When there are multiple (including two) collision prevention pads 11 on the same side, the multiple collision prevention pads 11 are arranged at intervals in the first direction a.
[0053] Further preferably, the collision prevention pad 11 includes a connected flat pad portion and a limiting portion, making the collision prevention pad 11 in an L shape. For the collision prevention pad 11 on one side of the hanging beam 1 in the second direction b, it can abut against the top of the battery module 3 through the flat pad portion and abut against the side portion of the battery module 3 in the second direction b through the flat pad portion; thus, the relative position of the hanging beam 1 and the battery module 3 in the second direction b can also be limited by the collision prevention pads 11 on both sides of the hanging beam 1 in the second direction b.
[0054] Preferably, the thickness of the flat pad portion is h, and 5mm ≤ h ≤ 30mm, so that the collision prevention pad 11 can effectively play a buffering role and avoid crushing the battery module 3 when the hanging beam 1 descends towards the battery module 3.
[0055] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
