Description

Technical Field

[0001] This utility model relates to the field of energy storage battery transportation technology, and in particular to a battery pack loading and unloading device. Background Technology

[0002] During the installation and maintenance of energy storage cabinets, the handling and placement of battery packs are usually accomplished using forklifts. The common practice is to place the battery packs directly on the forklift arms, lift the battery packs to a suitable height, and then manually push or pull them into or out of the cabinet.

[0003] This method has certain shortcomings. On the one hand, the battery pack is in direct contact with the forklift during handling, resulting in significant resistance when pushing, requiring considerable effort from operators, and leading to low efficiency. On the other hand, the battery pack is prone to friction and abrasion during pushing or pulling, affecting its appearance and even posing safety hazards. Therefore, the existing methods for loading and unloading battery packs still have room for improvement in terms of convenience and safety. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, the technical problem to be solved by this utility model is to propose a battery pack loading and unloading cabinet device, which adopts the following technical solution:

[0005] A battery pack loading / unloading cabinet device includes a support base, the support base being provided with a forklift slot for inserting a forklift arm;

[0006] A support platform is provided on the aforementioned support base, and a transport roller for supporting and transporting the battery pack is laid on the aforementioned support platform. Several side limiting components are provided on both sides of the aforementioned support platform.

[0007] The aforementioned support base is equipped with a push plate, which is detachably fixed to the frame of the battery pack. Driven by the telescopic mechanism, the push plate moves back and forth along the transport direction of the transport roller to push the battery pack in or pull it out.

[0008] As a further improvement, the telescopic mechanism includes a fixed seat, a scissor linkage assembly, and a motor, all mounted on the support base. The two legs on the transmission side of the scissor linkage assembly are slidably mounted in the track groove of the push plate via hinged seats, while the two legs on the drive side are hinged to the fixed seat via a tensioning mechanism. The motor drives the tensioning mechanism to control the extension or retraction of the scissor linkage assembly, thereby driving the push plate to move forward or backward along the conveying direction of the transport roller.

[0009] As a further improvement, the opening and closing mechanism includes a guide rail mounted on the fixed base, a slider slidably mounted inside the guide rail, and the slider hinged to the drive-side support leg of the scissor linkage assembly; the motor is a rotary motor, and the output end of the rotary motor is provided with a gear, the slider meshing with the gear, and the rotary motor rotating drives the slider to slide inside the guide rail, causing the two drive-side support legs of the scissor linkage assembly to open or close.

[0010] As a further improvement, the aforementioned fixed base includes upper and lower guide rails, with sliders slidably disposed within each of the guide rails. The gear is located between the two guide rails and simultaneously meshes with both upper and lower sliders.

[0011] As a further improvement, a connecting plate is provided on the rear side of the push plate, and the connecting plate has the aforementioned track groove. The connecting plate and the push plate are detachably connected to each other, and the push plate has a number of bolt holes for connecting the battery pack frame.

[0012] As a further improvement, the aforementioned support platform includes two horizontally arranged square frames, and several of the aforementioned transport rollers are rotatably arranged within the aforementioned square frames to form two parallel transport paths.

[0013] As a further improvement, a plurality of side limiting members are respectively provided on the outer sides of the two aforementioned square frames. The side limiting members are horizontal wheels, which make rolling contact with the side wall of the battery pack.

[0014] As a further improvement, the lower side of the aforementioned support base is provided with several legs for supporting the support base to form the aforementioned forklift slot.

[0015] As a further improvement, the entrance to the forklift bay is equipped with a positioning element.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] Firstly, in this invention, the support base is equipped with a forklift slot, allowing the forklift arm to be directly inserted and the entire device lifted. The battery pack is placed on the transport roller, changing from sliding friction to rolling friction, making pushing easier. The side limit wheels fit snugly against the side walls of the battery pack, providing lateral guidance and preventing deviation. The push plate is located on the end face of the battery pack and is pushed forward or pulled back under the drive of the telescopic mechanism. It can also be fixed to the battery pack frame through bolt holes, ensuring smooth loading and unloading, reducing manual labor and the risk of paint damage.

[0018] Secondly, in this utility model, the telescopic mechanism consists of a fixed base, a scissor linkage, a guide rail, a slider, a gear, and a motor. The motor drives the gear, which in turn pushes the slider to slide along the guide rail. The slider drives the scissor linkage to open and close, and the other end of the linkage slides within the push plate's track groove, thus achieving linear reciprocating motion of the push plate. The fixed base is equipped with upper and lower guide rails, and the gear simultaneously meshes with the upper and lower sliders, ensuring consistent movement on both sides, uniform force on the push plate, preventing tilting, and guaranteeing stable movement of the battery pack.

[0019] Thirdly, this utility model features a connecting plate and bolt holes on the push plate, allowing for detachable connection to the battery pack frame and adaptability to battery packs of different specifications. The support platform consists of two square frames and transport rollers, forming parallel conveying paths for more even load distribution. A reserved space exists between the two conveying paths, allowing the forklift arm to lower into the reserved space when loading the battery pack, placing the battery pack on the transport rollers. The outer horizontal wheels roll in contact with the sidewalls of the battery pack, further ensuring smooth transport. Support legs are installed below the support base to create a forklift slot, and a positioning element is provided at the entrance to facilitate forklift arm insertion and alignment, improving operational safety.

[0030] To facilitate understanding by those skilled in the art, the structure of this utility model will now be described in further detail with reference to the accompanying drawings:

[0031] In the description of this utility model, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. The terms "part," "side," "end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on this utility model.

[0032] like Figures 1-3 As shown, a battery pack loading and unloading cabinet device includes a support base 1, and a forklift slot 11 is provided below the support base 1, which can be inserted with the forklift arm 4 of a forklift to lift and transport the device as a whole.

[0033] like Figure 1 As shown, a support platform 2 is provided on the support base 1. Several transport rollers 22 are rotatably mounted on the support platform 2 in the front-to-back direction to support and transport the battery pack 3 forward or backward in the transport direction. A push plate 12 is provided at the rear end of the support base 1. The push plate 12 can abut against the end face of the battery pack 3 or be fixed to the edge of the battery pack 3 by fasteners. When the battery pack 3 is placed on the support platform 2, its bottom contacts the transport rollers 22. The push plate 12 pushes the battery pack 3. The rotation of the rollers reduces friction and facilitates the movement of the battery pack 3 on the support platform 2.

[0034] Furthermore, such as Figures 1-3 As shown, limiting components are arranged on both sides of the support platform 2 to provide lateral limiting and guiding for the battery pack 3 during the conveying process, ensuring that the battery pack 3 moves stably along the roller direction.

[0035] Preferably, a telescopic mechanism is also included, such as Figure 1 and Figure 4As shown, the push plate 12 moves back and forth along the transport direction of the transport roller 22 under the drive of the telescopic mechanism, so as to push the battery pack 3 in or pull it out on the transport roller 22. That is, when the push plate 12 moves forward, it can push the battery pack 3 into the cabinet, and when the push plate 12 moves backward, it can drive the battery pack 3 out of the cabinet, thereby realizing the operation of the battery pack 3 entering and leaving the cabinet.

[0036] Specifically, such as Figures 2-4 As shown, the telescopic mechanism is mounted on the support base 1 and includes a fixed base 13, a scissor linkage assembly 14, and a motor 15. The fixed base 13 is fixed to the frame of the support base 1 and serves as the mounting base for the entire telescopic mechanism. The scissor linkage assembly 14 is formed by hinged ends and intersections of multiple cross links, with two legs on each side. The side closer to the battery pack 3 is the transmission side, and the side closer to the motor 15 is the drive side. The ends of the two legs on the transmission side engage with the track groove 171 at the rear of the push plate 12, and the ends of the legs are equipped with hinge seats 16, which can slide in the front-back direction within the track groove 171, so that the telescopic motion of the scissor linkage assembly 14 is converted into the linear reciprocating motion of the push plate 12 along the transport direction. The other side of the scissor linkage assembly 14, i.e., the two legs on the drive side, are hinged to the fixed base 13 through a tensioning mechanism.

[0037] like Figure 3 and Figure 5 As shown, the opening and closing mechanism is mounted on the fixed base 13 and is used to drive the opening and closing of the scissor linkage assembly 14. A crossbar is provided on the fixed base 13, and a guide rail 131 is arranged on the crossbar, with a slider 132 slidably installed inside it.

[0038] The motor 15 is preferably a rotary motor, fixedly mounted in the middle of the fixed base 13. A gear 151 is provided at the output end of the motor 15. The slider 132 can reciprocate along the guide rail 131, and a rack segment is provided on the slider 132. The motor 15 is preferably a rotary motor, fixedly mounted in the middle of the fixed base 13. A gear 151 is provided at the output end of the motor 15, and meshes with the rack segment of the slider 132. The slider 132 is hinged to the drive-side support leg of the scissor linkage assembly 14. When the slider 132 moves within the guide rail 131, it can drive the drive-side support leg of the scissor linkage assembly 14 to move synchronously, thereby closing or opening the two support legs on the drive side, thus controlling the extension or shortening of the scissor linkage assembly 14, and driving the push plate 12 to move forward or backward along the transport direction of the transport roller 22.

[0039] Preferably, to improve force balance and motion synchronization, the fixed base 13 is provided with two parallel guide rails 131 arranged side by side, which respectively engage with the upper slider 132 and the lower slider 132. Both sliders 132 are equipped with rack segments. The gear 151 of the rotary motor is located between the two guide rails 131 and meshes with both the upper and lower sliders 132 simultaneously, realizing the synchronous linear motion of the two sliders 132. This arrangement makes the scissor linkage assembly 14 symmetrically subjected to force, shortens the stroke of a single slider 132, and improves the stability of the transmission.

[0040] Through the above structure, the rotational motion of the motor 15 is ultimately converted into the linear reciprocating motion of the push plate 12. The operation is smooth and the force is transmitted evenly. It can both push the battery pack 3 in and pull it out, ensuring the reliability of the device in use.

[0041] like Figure 4 As shown, a connecting plate 17 is installed on the rear side of the push plate 12. The connecting plate 17 is fixedly connected to the push plate 12 by bolts, which facilitates disassembly or replacement when needed, adapts to different battery pack 3 sizes, and facilitates maintenance. The connecting plate 17 has a track groove 171, which provides sliding space for the drive-side support of the scissor linkage assembly 14. There are several bolt holes on the front of the push plate 12. During installation, the push plate 12 can be fixed to the frame of the battery pack 3 by bolts, ensuring that the push plate 12 can firmly pull the battery pack 3 during the cabinet removal operation.

[0042] In one specific embodiment, the support platform 2 consists of two horizontally parallel square frames 21. Each square frame 21 contains several rotatably mounted transport rollers 22. The two sets of transport rollers 22 together form two parallel conveying paths, providing uniform load-bearing capacity when the battery pack 3 is placed on them, preventing localized stress that could cause roller deformation or unstable operation. A reserved space is left between the two square frames 21. When loading the battery pack 3, the forklift arm 4 can be lowered from this reserved space, allowing the battery pack 3 to be smoothly placed onto the transport rollers 22, thus achieving a smooth transition of the battery pack 3 from the forklift to the cabinet loading device.

[0043] like Figure 3 As shown, several side limiting members 23 are evenly distributed on the outside of the two square frames 21. The side limiting members 23 are horizontal wheels that can rotate freely. The horizontal wheels maintain rolling contact with the side wall of the battery pack 3, which can provide guidance during the process of pushing the battery pack 3 in or pulling it out, prevent the battery pack 3 from shifting laterally, and ensure that the transportation process is stable and reliable.

[0044] like Figures 1-3As shown, several support feet 18 are installed on the lower side of the support base 1 to lift the base as a whole, thereby forming a forklift slot 11 space at the bottom to support the entire device. In order to improve the docking efficiency between the forklift and the device, a positioning element 19 is provided at the entrance of the forklift slot 11. In one specific embodiment, the positioning element 19 is a square frame set at the entrance of the forklift slot 11, which can provide guidance when the forklift arm 4 is inserted, preventing the forklift arm 4 from being inserted too far off-center, causing the device to tilt or even tip over during lifting and transportation.

[0045] During the cabinet insertion operation, the forklift arm 4 is first inserted into the positioning part of the support base 1 and extended into the forklift slot 11. Simultaneously, the forklift arm 4 is secured to the cabinet insertion device using strapping, ensuring a stable connection between the device and the forklift. Then, another forklift transports the battery pack 3 to the support platform 2 of the device. The forklift arm 4 of the forklift transporting the battery pack 3 is lowered from the reserved space between the two square frames 21, allowing the battery pack 3 to be stably placed on the two sets of transport rollers 22. The operator moves the push plate 12 forward to a position where it abuts against the edge of the battery pack 3 and secures the push plate 12 to the battery pack 3 with bolts. The forklift is then operated to lift the device along with the battery pack 3 to the height where it aligns with the cabinet. The rotary motor drives the telescopic mechanism, pushing the push plate 12 forward along the transport direction. The battery pack 3 moves forward under the action of the side limiting part 23 until it is pushed into the cabinet. After the cabinet insertion is completed, the connection between the push plate 12 and the battery pack 3 is released, and the cabinet insertion device is removed.

[0046] During the unloading operation, the device is first placed on and secured on the forklift arm 4. The forklift is then operated to raise the device to the position where it aligns with the cabinet. Next, the motor 15 is started to drive the push plate 12 forward, bringing it to the front of the battery pack 3. The push plate 12 is then securely connected to the battery pack 3 using bolts. The motor 15 is then started again, causing the telescopic mechanism to move the push plate 12 backward along the transport roller 22, thus smoothly pulling the battery pack 3 out of the cabinet and placing it on the transport roller 22. At this point, the forklift can transport the loading device along with the battery pack 3 out of the cabinet, completing the unloading process.

[0047] In summary, the battery pack 3 loading / unloading device of this utility model, through the cooperation of the support base 1, support platform 2, transport roller 22, side limiting member 23, push plate 12, and telescopic mechanism, achieves smooth transfer of the battery pack 3 inside and outside the cabinet. This device can be flexibly coordinated with forklifts during use, not only improving the efficiency of battery pack 3 loading and unloading from the cabinet but also reducing the intensity of manual operation and preventing damage to the paint and bottom of the battery pack 3.

[0048] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
