Description

Technical Field

[0001] This invention relates to the field of handling equipment technology, and in particular to a nickel-metal hydride battery module loading and unloading vehicle. Background Technology

[0002] In fields such as new energy storage equipment and industrial power systems, nickel-metal hydride (NiMH) batteries have become core energy storage components due to their advantages of high energy density, long cycle life, and strong structural stability. Among them, the dual-cell module of a 75kg heavy-duty cylindrical NiMH battery (weighing 150kg per unit) is the mainstream assembly unit. The cabinet assembly of the dual-cell module is a core link in the production of end products. It requires the sequential completion of key operations such as transfer, height adaptation, position calibration, cabinet pushing, and safety protection. Its assembly efficiency, accuracy, and safety directly affect the connection reliability and service life of the product.

[0003] Currently, the industry primarily uses a combination of forklifts, crane hoists, slings, and other simple tools and equipment, along with manual assistance, to assemble these heavy-duty nickel-metal hydride (NiMH) battery modules into storage. Due to the relatively large weight and volume of NiMH battery modules, manual assistance during storage is ineffective. It's difficult to accurately align the modules, and they are prone to collisions with racks and other objects during assembly, making it unsuitable for the efficient, precise, and safe assembly requirements of modern production lines.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0021] This invention provides a cabinet-mounted lifting vehicle for nickel-metal hydride battery modules, such as... Figures 1-8 As shown, this cabinet-loading lifting vehicle adopts a modular design concept, mainly including core modules such as a load-bearing moving mechanism 1, a lifting mechanism 2, an adaptive mechanism 4, a pushing mechanism 6, a blocking mechanism 8, and a limiting mechanism 9. These modules work together to achieve a fully integrated operation for the cabinet-loading and assembly of heavy-duty nickel-metal hydride battery modules. The overall dimensions of the equipment are 2500mm × 500mm × 500mm (length × width × height), with a lifting range covering 500-2300mm and a load capacity ≥200kg, suitable for assembling 75kg-class single / dual-cell modules. The specific structure of each module is as follows: The load-bearing moving mechanism 1, serving as the basic support and moving unit of the equipment, moves independently on the ground. The main body of the load-bearing moving mechanism 1 is a reinforced support frame welded from high-quality angle steel, fixed to the equipment's load-bearing frame with M12 high-strength bolts, and equipped with rollers at the bottom. The load-bearing moving mechanism 1 can be configured as either electrically driven or manually propelled, depending on requirements.

[0022] Lifting mechanism 2 is located above load-bearing moving mechanism 1. Lifting power mechanism 3 is located on load-bearing moving mechanism 1 and is used to drive lifting mechanism 2 to move up and down. The combination of lifting mechanism 2 and lifting power mechanism 3 provides height adjustment function for the cabinet lifting vehicle.

[0023] An adaptive mechanism 4 moves horizontally on the lifting mechanism 2, and the nickel-metal hydride battery assembly is placed on the adaptive mechanism 4. One or more fixing mechanisms 5 are disposed on the lifting mechanism 2; each fixing mechanism 5 includes a fixing block 51, which moves towards and away from the adaptive mechanism 4. When the fixing block 51 moves towards the adaptive mechanism 4 and presses against it, it restricts the sliding of the adaptive mechanism 4; when the fixing block 51 moves away from the adaptive mechanism 4, separating it from the adaptive mechanism 4, the adaptive mechanism 4 can move freely in the horizontal direction, including slight rotation and translation.

[0024] A pushing mechanism 6 slides on the adaptive mechanism 4; the pushing mechanism 6 includes a pushing plate 61 that abuts against one end face of the nickel-metal hydride battery assembly. A pushing power mechanism 7, disposed on the adaptive mechanism 4, is used to drive the pushing mechanism 6 to slide. The pushing mechanism 6 is used to push the nickel-metal hydride battery assembly out of the adaptive mechanism 4.

[0025] The blocking mechanism 8 rotates on the adaptive mechanism 4; the blocking mechanism 8 includes a blocking plate 81 that abuts against the other end face of the nickel-metal hydride battery assembly; used to prevent the nickel-metal hydride battery assembly from falling out of the adaptive mechanism 4 during transportation.

[0026] The limiting mechanism 9 is fixedly connected to the adaptive mechanism 4, and the limiting mechanism 9 is attached to the side of the nickel-metal hydride battery assembly to form a vertical limit on the nickel-metal hydride battery assembly, ensuring the stability of the nickel-metal hydride battery assembly during transportation and assembly.

[0027] The specific operating procedure for this cabinet lifting vehicle is as follows: S1: Battery Module Loading: Place the manufactured nickel-metal hydride (NiMH) battery module into the adaptive mechanism 4. Operate the fixing mechanism 5 to fix the position of the adaptive mechanism 4, install the upper limit mechanism 9, and operate the blocking mechanism 8 to make the blocking plate 81 abut against the end face of the NiMH battery module. The blocking plate 81 and the push plate 61 simultaneously abut against both ends of the NiMH battery module to fix the battery module and prevent it from shaking. If necessary, the fixing mechanism 5 can be released before loading, allowing the adaptive mechanism 4 to better align with the NiMH battery module by adjusting its position.

[0028] S2: Battery component handling: Transfer the equipment to the cabinet entry position, and control the lifting mechanism 2 to rise to the target height according to the height of the cabinet entry interface.

[0029] S3: Preparation before cabinet entry: The operator rotates the blocking plate 81 of the blocking mechanism 8 to release it from obstruction of the battery assembly. The blocking plate 81 flips to a 90° horizontal position and fits against the bottom of the table. At the same time, the limiting mechanism 9 is removed to ensure that the battery assembly pushing path is unobstructed. If necessary, the fixing mechanism 5 can be released to allow the adaptive mechanism 4 to better align with the cabinet entry interface by adjusting its position.

[0030] S4: Push into cabinet: The operator controls the push mechanism 6 to slide and push the battery pack out of the adaptive mechanism 4 and into the cabinet. During the push, the adaptive mechanism 4 is driven by the reaction force of the cabinet and automatically corrects the lateral deviation and entry angle of the battery pack to avoid jamming. If the pushing resistance exceeds 300N and the rocker wheel generates a damping sensation, the operator should immediately stop pushing and check the alignment status. After troubleshooting, push can continue.

[0031] S5: Reset and Finishing: After the battery pack is fully pushed into the cabinet mounting slot, the operator controls the pushing mechanism 6 to reverse and reset, completing the single cell assembly in the cabinet; then the blocking plate 81 is flipped up and locked, and the equipment can be transferred to the next station for repeated operation.

[0032] The lifting power mechanism 3 can use various existing lifting power devices or structures. As a preferred embodiment of the present invention, the lifting power mechanism 3 adopts the following structure: It includes lifting components symmetrically arranged on both sides of the lifting mechanism 2. Each lifting component includes a first lower connecting rod 31, a second lower connecting rod 32, a first upper connecting rod 33, a second upper connecting rod 34 and a first power device 35. The first lower connecting rod 31 and the second lower connecting rod 32 are hinged at the middle section; the first upper connecting rod 33 and the second upper connecting rod 34 are hinged at the middle section. The bottom end of the first lower connecting rod 31 is hinged to the load-bearing moving mechanism 1; The bottom end of the second lower connecting rod 32 slides horizontally on the load-bearing moving mechanism 1; The bottom end of the first upper connecting rod 33 is hinged to the top end of the first lower connecting rod 31, and the top end of the first upper connecting rod 33 is hinged to the lifting mechanism 2. The bottom end of the second upper connecting rod 34 is hinged to the top end of the second lower connecting rod 32, and the top end of the first upper connecting rod 33 slides horizontally on the lifting mechanism 2. The first power unit 35 drives the two first lower connecting rods 31 and the second lower connecting rod 32 on both sides to rotate synchronously.

[0033] The above structure not only provides symmetrical thrust to both sides of the lifting mechanism 2, making the lifting mechanism 2 rise more smoothly, but also the lifting assembly that forms the linkage assembly can adjust the height of the lifting mechanism 2 at any position, so that this cabinet lifting vehicle can adapt to various work scenarios with different height requirements.

[0034] Preferably, the first power device 35 is a power telescopic rod, such as an electro-hydraulic push rod or an electric lead screw push rod; The lifting power mechanism 3 also includes a connecting plate 36 whose two ends are fixedly connected to the bottom ends of two second lower connecting rods 32 respectively, and a connecting rod 37 whose two ends are fixedly connected to the middle sections of two first lower connecting rods 31 respectively; the connecting rod 37 is provided with an extension section 38 that extends radially and toward the lifting mechanism 2; The first power unit 35 is hinged at one end to the connecting plate 36 and at the other end to the extension section 38.

[0035] The first lower connecting rod 31 and the second lower connecting rod 32 on both sides of the lifting mechanism 2 can be connected to each other through the connecting plate 36 and the connecting rod 37, so that they move synchronously and the lifting mechanism 2 is more stable when lifting. After the connecting plate 36 is combined with the extension section 38, it can form a force-reducing lever structure when the first power device 35 drives the lifting mechanism 2 to rise. In this way, when the lifting mechanism 2 interferes with the outside, the first power device 35 will not generate excessive thrust on the lifting mechanism 2, which would damage the battery assembly.

[0036] Because the stopping position of the load-bearing moving mechanism 1 varies considerably each time, the displacement required for the adaptive mechanism 4 to align with the cabinet interface may also differ each time. To maximize the automatic horizontal adjustment capability of the adaptive mechanism 4 and enable it to adapt to various positional requirements, it is preferable to install multiple load-bearing rollers 21 on the top surface of the lifting mechanism 2 and multiple recessed limiting grooves 41 on the bottom surface of the adaptive mechanism 4. When the adaptive mechanism 4 is placed on the lifting mechanism 2, each load-bearing roller 21 abuts against the end face of a limiting groove 41, ensuring that each load-bearing roller 21 can only slide within one limiting groove 41.

[0037] To prevent the adaptive mechanism 4 from detaching from the lifting mechanism 2, and to prevent the adaptive mechanism 4 from sliding too sensitively on the lifting mechanism 2, it is preferable to provide multiple through-holes 42 on the bottom surface of the adaptive mechanism 4, and multiple limiting posts 22 on the top surface of the lifting mechanism 2. Each limiting post 22 passes through a limiting hole 42, and the diameter of the limiting hole 42 is larger than that of the limiting post 22. Additionally, a limiting plate 23 is provided on the top of each limiting post 22, and the diameter of the limiting plate 23 is larger than that of the limiting hole 42. The large-diameter limiting plate 23 prevents the limiting post 22 from detaching from the limiting hole 42, thus ensuring that the adaptive mechanism 4 will not detach from the lifting mechanism 2. Furthermore, a certain amount of friction can be formed between the bottom surface of the limiting plate 23 and the top surface of the limiting hole 42, thereby preventing the adaptive mechanism 4 from sliding too sensitively on the lifting mechanism 2 and ensuring that the adaptive mechanism 4 will not easily wobble after being aligned with the cabinet interface. The limiting plate 23 can be connected to the limiting post 22 via a threaded structure, which enables the limiting plate 23 to be quickly clamped and unlocked, and the magnitude of the friction force can be adjusted.

[0038] The fixing mechanism 5 can be implemented using various existing abutment devices or structures. As a preferred embodiment of the present invention, the fixing mechanism 5 adopts the following structure: In addition to the fixed block 51, the fixing mechanism 5 also includes a fixed base 52, a handle 53, and a self-locking linkage 54. The fixed base 52 is fixedly mounted on the lifting mechanism 2. The fixed block 51 slides horizontally on the fixed base 52. The handle 53 is L-shaped, with one end hinged to the fixed base 52. One end of the self-locking linkage 54 is hinged to the L-shaped corner of the middle section of the handle 53, and the other end is hinged to the fixed block 51. During operation, simply moving the handle 53 will cause the fixed block 51 to move via the self-locking linkage 54. The fixed block 51 has a V-shaped convex structure on the side facing the adaptive mechanism 4, and the adaptive mechanism 4 has a V-shaped concave structure that matches the V-shaped convex structure, thereby achieving quick and stable fixing of the fixed block 51 to the adaptive mechanism 4.

[0039] To prevent the fixing mechanism 5 from loosening during transportation and thus releasing the fixation of the adaptive mechanism 4, the fixing mechanism 5 needs to have a certain self-locking capability. We can denote the hinge point between the handle 53 and the fixed seat 52 as point A, the hinge point between the handle 53 and the self-locking link 54 as point B, and the hinge point between the self-locking link 54 and the fixed block 51 as point C. When the fixed block 51 abuts against the adaptive mechanism 4, points A, B, and C are aligned in the horizontal direction. At this time, the self-locking link 54 should be almost or directly in contact with the fixed seat 52. In this way, unless the handle 53 is manually pried open, the self-locking link 54 will hardly rotate on its own, thereby achieving the self-locking of the fixed block 51.

[0040] Preferably, multiple rollers 43 are provided at the bottom of the adaptive mechanism 4. When the battery pack is placed into the adaptive mechanism 4, it will fall on the rollers 43. In this way, when the battery pack is pushed out of the adaptive mechanism 4, the rollers 43 can reduce the wear and collision of the battery pack and ensure the safety of the battery pack.

[0041] The pushing power mechanism 7 can use various existing sliding devices or structures. As a preferred embodiment of the present invention, the pushing power mechanism 7 adopts the following structure: The pushing power mechanism 7 includes a second power unit 71, a driving pulley 72, a driven pulley 73, and a belt 74; the second power unit 71 drives the driving pulley 72 to rotate; the driving pulley 72 and the driven pulley 73 are respectively located at both ends of the adaptive mechanism 4; the belt 74 wraps around the driving pulley 72 and the driven pulley 73; the pushing mechanism 6 is provided with a clamping structure 62, which clamps the belt 74.

[0042] The second power unit 71 can be electrically controlled directly using a motor, or manually controlled using a combination of a rocker wheel and a reduction gear set. This invention preferably uses manual control, allowing the operator to promptly control parameters such as the pushing speed and the position of the adaptive mechanism 4 based on feedback from the damping sensation during the battery assembly's movement. The rocker wheel uses a non-slip rubber disc with anti-slip textured surfaces for easy grip. The reduction gear set employs a helical gear transmission design with a 1:50 ratio, amplifying the operator's rotational force by 50 times. A thrust feedback device can also be installed within the reduction gear set, connected to the rocker wheel transmission; when the pushing resistance exceeds 300N, the rocker wheel generates a noticeable damping sensation.

[0043] The blocking mechanism 8 has a high-strength engineering plastic plate 81 with a width consistent with the equipment table surface. The blocking mechanism 8 is also equipped with a locking pin assembly for locking the blocking plate 81. The locking pin assembly consists of a metal locking pin, a spring return device, and a positioning slot. The locking pin is installed on the side wall of the adaptive mechanism 4, the spring return device is connected to the locking pin, and the positioning slot is opened at the corresponding position of the adaptive mechanism 4. When the blocking plate 81 is flipped up to 90°, the locking pin automatically inserts into the positioning slot under the action of the spring to achieve locking.

[0044] One or more roller sets 91 are provided at the bottom of the limiting mechanism 9. The roller sets 91 abut against the side of the nickel-metal hydride battery assembly. In this way, when the battery assembly is pushed out of the adaptive mechanism 4, the roller sets 91 can reduce the wear and collision of the battery assembly and ensure the safety of the battery assembly.
