[0002] In the lithium-ion battery energy storage sector, packing battery packs into containers places high demands on the handling trolley's flexibility, load capacity, and telescopic and lifting precision. Traditional forklifts transporting PACK modules into containers require high operator skills and high lifting precision. During actual handling, the module packs can easily collide with the container's left and right limit plates and height partitions, causing deformation. Therefore, for scenarios where packing battery packs into containers requires high lateral telescopic precision, height accuracy, and load capacity, there is an urgent need for a handling trolley that can flexibly move and detect lateral and lifting position in real time.

[0029] The following will clearly and completely describe the technical solution of this application in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of this application.

They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0031] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0032] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that ordinary technicians in this field can implement them. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0033] The present application discloses a battery module transporting mechanism, which is used to transport battery modules, so that they can cross obstacles, pass through openings, etc. for fork loading operations, and finally perform stacking and destacking operations of multiple rows of goods under complex working conditions, so that the battery modules can be smoothly stacked in the cabinet, or the battery modules can be taken out of the cabinet in sequence. The cabinet described above may include a frame and support plates, the support plates are arranged on both sides of the frame, two support plates on the same horizontal plane form a group, and a avoidance gap is provided between the two, which work together to achieve support for the battery module and will not interfere with the operation of the battery module transporting mechanism. It should be emphasized that the distance between two adjacent support plates in the vertical direction should be greater than the thickness of the battery module, so as to provide operating space for the battery module transporting mechanism and avoid interference with the battery module transporting mechanism.

[0034] The following combination Figures 1 to 3 The structure and working principle of the battery module handling mechanism are described in detail. Figure 1 As shown, the battery module transport mechanism includes a mobile rack 1, an electric control box module 2, a transverse module 3 and a drive module 4, wherein the transverse module 3 and the drive module 4 are arranged on the mobile rack 1, and the electric control box module 2 is independently arranged relative to the mobile rack 1, and a pulley 12 is provided at the bottom thereof. Signals are transmitted between the electric control box module 2 and the mobile rack 1 through a connecting plug. In this embodiment, the connecting plug between the mobile rack 1 and the electric control box module 2 adopts an aviation quick-connect connector, and the split design can facilitate the movement of the equipment and provide convenience for the maintenance of the equipment.

[0035] Preferably, the mobile rack 1 includes a frame 11, pulleys 12, armrests 13, and an extension plate 14. The frame 11 is provided with openings on both sides along the second direction to avoid the transverse module 3, allowing the transverse module 3 to drive the battery module to move along the first direction and the second direction without interfering with it. The pulleys 12 and armrests 13 cooperate to achieve the movement of the mobile rack 1. The armrests 13 can be provided in multiple groups and arranged at different positions of the frame 11 to facilitate pushing the frame 11 from different positions. In this embodiment, four armrests 13 are provided. In this embodiment, the pulleys 12 provided on the electric control box magic module 1 and the pulleys 12 provided on the mobile rack 1 are both pulleys 12 with brake pads. When the mobile rack 1 and the electric control box module 2 do not need to move, the pulleys 12 can be locked by the brake pads to prevent the mobile rack 1 or the electric control box module 2 from sliding.

[0036] Specifically, extension plates 14 are provided on both sides of the loading end of the mobile rack 1, near the bottom, in two parallel groups. Feed guide plates 15 are provided on each of the extension plates 14. The feed guide plates 15 include a vertical portion and an inclined portion. The two opposing inclined portions form an outwardly flared trumpet shape in the second direction. The distance between the two corresponding vertical portions is adapted to the width of the battery module, allowing the battery module to be centered relative to the transverse platform 33 along the first direction. The specific mode of operation will be further described later when describing the transverse module 3. In addition, positioning guide blocks 16 are provided on both sides of the unloading end of the mobile rack 1, near the bottom, in parallel. When the cabinet is docked, the two positioning blocks 16 can extend into the cabinet, facilitating docking with the cabinet, achieving positioning of the mobile rack 1, and facilitating the removal and placement of the battery module relative to the cabinet.

[0037] Furthermore, a base plate is provided between the extension plates 14, and a counterweight 17 is provided on the base plate. It should be noted that, two of the pulleys 12 provided on the mobile rack 1 are located at two corners of the base plate away from the frame body 11, and the other two pulleys 12 are provided at two corners of the bottom of the frame body 11 away from the base plate, so as to keep the force on the mobile rack 1 stable and prevent the problem of overturning. However, when the transverse module 3 places the battery module into the cabinet (or when the transverse module 3 takes the battery module out of the cabinet), in order to avoid interference between the cabinet and the mobile rack 1, the transverse module 3 will extend out of the mobile rack 1, and the center of gravity will shift to one side. The provided counterweight 17 can prevent the mobile rack 1 from overturning.

[0038] In this embodiment, in order to facilitate the description of the battery module handling mechanism, the loading end and the unloading end are defined as follows, and the scene when the battery module is placed into the cabinet is used as a reference for description. We call the battery module placed on the transverse module 3 the loading of the battery module, and the end of the mobile rack 1 for loading the battery module is defined as the loading end; sending the battery module into the cabinet is called the unloading of the battery module, and the end close to the mobile rack 1 during unloading is defined as the unloading end; in addition, Figure 1 The X direction is defined as a first direction, the Y direction is defined as a second direction, and the Z direction is defined as a third direction.

[0039] As a preference, see Figure 2 As shown, the transverse module 3 includes a mounting base 31, a transverse slide 32, a transverse platform 33 and a transverse platform driving component 34. The mounting base 31 is a cross-shaped plate with four protruding wings, two of which are slidably connected to the inner frame of the frame 11. The transverse slide 32 is fixedly set on the mounting base 31 and passes through the other two wings. The transverse platform 33 cooperates with the transverse slide 32. The transverse platform driving component 34 is set on the mounting base 31, and the transverse platform driving component 34 is used to drive the transverse platform 33 to move along the second direction.

[0040] In this embodiment, two groups of transverse slide rails 32 are arranged in parallel, and the two ends of the transverse slide rails 32 respectively extend out of a part of the mounting base 31. At the same time, in order to avoid interference between the battery module and the cabinet during loading and unloading operations, the width of the transverse platform 33 is smaller than the width of the battery module, and the outer margins of the two transverse slide rails 32 are not greater than the width of the transverse platform 33.

[0041] Specifically, the transverse platform driving component 34 includes a driving motor 341, a driving gear (not shown in the figure) and a rack 342. The driving end of the driving motor 341 is equipped with a driving gear, and a rack 342 is provided under the transverse platform 33. The driving gear and the rack 342 are engaged, and the driving motor 341 drives the driving gear to rotate, thereby driving the transverse platform 33 to move along the second direction, driving the battery module to realize loading and unloading operations.

[0042] Furthermore, a limit baffle 35 is provided at each end of the transverse slide 32 to limit the maximum stroke of the transverse platform 33 and prevent the transverse platform 33 from detaching from the transverse slide 32; moreover, a limit stop block 36 is provided on the side of the transverse platform 33 close to the loading end, which cooperates with the feeding guide plate 15 to further limit the position of the battery module relative to the transverse platform 33. At the same time, it can prevent the battery module from being touched and shifted when feeding the battery module relative to the cabinet body, thereby affecting the cabinet feeding operation.

[0043] Preferably, the battery module transport mechanism further includes a visual monitoring mechanism 5, which is provided on the mounting base 31, and the visual monitoring mechanism 5 is used to monitor the cabinet entry status of the battery module in real time; in this embodiment, the visual monitoring mechanism 5 includes an industrial camera.

[0044] Preferably, the driving module 4 includes a chain 41, a gear 42, a bearing 43 and a chain driving member 44. There are two groups of bearings 43, which are respectively slidably arranged on the upper and lower sides of the cavity of the mobile frame 1. The gears 42 are respectively arranged at both ends of the bearings 43. The chains 41 are connected end to end to form a closed ring structure. A group of chains 41 can be sleeved on two gears 42, and the rotation of the gear 42 is used to drive the chain 41 to transmit. A chain fixing block 37 is respectively provided on the two wing plates where the transverse platform 33 is slidably connected to the frame body 11. The chain 41 is connected to the mounting base 31 through the chain fixing block 37. A chain avoidance hole is provided on one side of the chain fixing block 37, and the chain 41 can pass through the chain avoidance hole. In this embodiment, the chain drive 44 is arranged at the bottom, which can drive the gear 42 to rotate by driving the bearing 43, and finally realize the transmission of the chain 41. The forward and reverse movements of the chain 41 can realize the lifting and lowering of the mounting base 31; in this embodiment, four chains 41 are used to drive the lifting to ensure the stability and safety of the lifting.

[0045] In this application, the battery module is placed on the transverse platform 33, and the transverse platform 33 slides along the extension direction of the transverse slide rail 32 to realize the sliding of the battery module in the horizontal direction. The driving module 4 can drive the transverse module 3 to move in the vertical direction, that is, it can drive the battery module to move in the vertical direction, and the mobile rack 1 is provided with openings at both ends along the sliding direction of the transverse platform 33, so that the loading and unloading of the battery module relative to the conveying mechanism can be completed (the unloading here is relative to the loading of the storage cabinet), which has very high flexibility.

[0046] When the battery module is loaded relative to the cabinet, first, the mobile frame 1 is positioned so that it is docked with the cabinet first, and then the transverse platform 33 is moved to the loading end. At this time, the upper surface of the transverse platform 33 is flush with the lower surface of the feed guide plate 15. The battery module is placed on the transverse platform 33 manually or by a robot. Under the action of the feed guide plate 15, the battery module is centered in the second direction relative to the transverse platform 33. The transverse platform 33 drives the battery module toward the cabinet until it extends into the interior of the cabinet. The transverse platform 33 drives the battery module down until the battery module is supported by the support plate of the cabinet. The transverse platform 33 continues to descend and disengages from the support for the battery module. The transverse platform 33 is reset and the next group of battery modules are loaded into the cabinet. When the battery module is unloaded from the cabinet, the action of the transverse platform 33 is reversed.

[0047] The above is only a preferred embodiment of the battery module transport mechanism disclosed in the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept of the present invention, and these all fall within the scope of protection of the present invention.
