Description

Technical Field

[0001] This utility model relates to a convenient battery pack transfer device, belonging to the technical field of battery pack transportation. Background Technology

[0002] In the production, storage, and transportation of battery packs, battery pack transfer devices are key tooling equipment to ensure their safe and efficient turnover. However, existing battery pack transfer devices have significant limitations when dealing with the complex requirements of real-world application scenarios, especially in ensuring the absolute stability of the battery packs and ease of operation.

[0003] The primary drawback is the insufficient constraint capability of existing devices on battery packs under dynamic operating conditions. When battery packs experience unavoidable vibrations, impacts, or tilting during vehicle transport or AGV handling, they are highly susceptible to unexpected displacement or even complete detachment within the transfer device. This displacement or detachment not only directly threatens the physical integrity of the battery pack casing, causing visible damage, but also poses a deeper risk of inducing short circuits or structural damage to the internal battery cells, leading to serious safety risks and significant economic losses. The limiting structures used in existing transfer devices often fail to adequately adapt to diverse and high-intensity stability requirements arising from different road conditions, handling speeds, or sudden bumps, resulting in uncertain protective effectiveness.

[0004] Furthermore, in an attempt to mitigate the risk of battery pack displacement during dynamic processes, existing designs often minimize the gap between the battery pack and the carrier surface of the transfer device. However, this compact design, undertaken for safety reasons, introduces operational obstacles. The excessively small gap makes it difficult for conventional automated or semi-automated handling tools, such as material handling grippers, to effectively reach the bottom of the battery pack for operation. Operators or equipment cannot smoothly maneuver the grippers through the extremely limited space between the battery pack and the transfer device to grasp or release the battery pack, severely hindering the efficiency of battery pack flow during loading and unloading, increasing the need for manual intervention and operational complexity. Summary of the Invention

[0005] Purpose of the invention: To solve the above-mentioned technical problems, this utility model provides a convenient battery pack transfer device. The device uses a rectangular support frame and multiple sets of spaced horizontal / vertical limiting blocks to work together to form a constraint structure in which the battery pack abuts in four directions. The layout design of the limiting blocks is optimized to retain sufficient operating space at the bottom of the battery pack, thus solving the problems of unstable limiting and difficulty in gripping.

[0006] Technical Solution: A convenient battery pack transfer device includes a support frame, which is a rectangular support frame made of square tubes. Lateral limiting blocks and longitudinal limiting blocks are respectively installed on the square tubes on both sides of the support frame. At least one set of lateral limiting blocks is arranged in pairs on the square tubes on both sides of the support frame, and two sets of longitudinal limiting blocks are arranged in pairs on the square tubes on both sides of the support frame. The longitudinal limiting blocks on each side of the support frame are located on both sides of the lateral limiting blocks. Adjacent lateral limiting blocks and longitudinal limiting blocks on each side of the support frame are spaced apart. The lateral limiting blocks on each side of the support frame are arranged opposite each other along the lateral direction of the support frame, and the longitudinal limiting blocks on each side of the support frame are arranged opposite each other along the longitudinal direction of the support frame. The two lateral end faces of the battery pack abut against the lateral limiting blocks on the square tubes on both sides of the support frame, and the two longitudinal end faces of the battery pack abut against the two sets of longitudinal limiting blocks.

[0007] This invention utilizes a rectangular support frame constructed of square tubes, with groups of lateral and longitudinal limiting blocks arranged on the lateral sides of the square tubes. These limiting blocks are spaced apart, ensuring that the lateral end faces of the battery pack abut against the lateral limiting blocks and the longitudinal end faces abut against the longitudinal limiting blocks, forming a multi-directional constraint structure. This addresses the risk of displacement and slippage caused by insufficient constraint on the battery pack in existing devices under dynamic operating conditions. Simultaneously, the spaced design preserves operating space at the bottom of the battery pack, providing gripping space for the material distribution gripper, thus balancing stability and ease of operation.

[0008] In a preferred embodiment, to limit the displacement of the battery pack in four directions, a limiting protrusion is provided extending upward from the upper surface of the lateral limiting block along the side end face of the lateral limiting block. The limiting protrusion is perpendicular to the upper surface of the lateral limiting block. The lateral limiting block and the longitudinal limiting block have the same structure, and the limiting protrusions of the lateral limiting block and the longitudinal limiting block are perpendicular to each other. The bottom surface of the battery pack abuts against the upper surfaces of the lateral limiting block and the longitudinal limiting block, and the two lateral end faces of the battery pack abut against the limiting protrusions of the lateral limiting block and the longitudinal limiting block, respectively.

[0009] By extending upwards from the side surfaces of the lateral and longitudinal limiting blocks, limiting protrusions are provided, so that the bottom surface of the battery pack fits against the upper surface of the limiting blocks and the side surfaces abut against the limiting protrusions, thus achieving an L-shaped three-dimensional limiting structure, which significantly enhances the rigid constraint on the horizontal direction of the battery pack.

[0010] In a preferred embodiment, in order to provide guidance during the hoisting of the battery pack, a guide ramp is provided on the surface of the limiting protrusion that abuts against the battery pack.

[0011] By setting a guide ramp between the limiting protrusion and the contact surface of the battery pack, the battery pack can achieve self-correction positioning during the falling process, avoiding collision damage caused by positional deviation and improving hoisting efficiency and safety.

[0012] In a preferred embodiment, to avoid frequent drilling on the square tube while enabling it to adapt to different battery pack sizes, a grooved profile is further provided on the horizontal square tube of the support frame. The grooved profile is provided between the square tubes on both sides of the support frame and the horizontal limiting block and the vertical limiting block. The horizontal limiting block and the vertical limiting block are slidably connected to the grooved profile through a moving component.

[0013] By adding grooved profiles and moving components, the horizontal / vertical limiting blocks are slidably connected to the profiles, enabling stepless adjustment of the limiting block positions. Multiple battery pack specifications can be quickly matched simply by moving along the grooves.

[0014] In a preferred embodiment, to simplify the adjustment process of the limiting block position, the moving component includes a slider, the slider matching the groove of the grooved profile, the lateral limiting block and the longitudinal limiting block having the same first through hole along the vertical direction, the slider having a second through hole matching the first through hole, and the lateral limiting block and the longitudinal limiting block being detachably connected to the slider after being bolted through the first through hole and the second through hole respectively.

[0015] By using a slider and a slot to cooperate, and by using bolts to pass through the through holes of the limit block and the slider to achieve a detachable connection, it is possible to make the slider and the limit block move synchronously after loosening the bolts and then fix them after tightening, which greatly improves the adjustment efficiency.

[0016] In a preferred embodiment, to facilitate the installation of the grooved profile and improve the reliability and load-bearing capacity of the installation, an installation plate is also included, which is symmetrically arranged along the vertical centerline of the longitudinal square tube of the support frame. The installation plate is arranged between the longitudinal square tube of the support frame and the grooved profile. The bottom surface of the installation plate is fixedly connected to the upper surface of the longitudinal square tube of the support frame, and the top surface of the installation plate is connected to the bottom surface of the grooved profile.

[0017] In a preferred embodiment, to facilitate the stacking, storage, and transportation of the transfer device, a stacking assembly is further included, which is installed on square tubes at both ends of the support frame. The stacking assembly includes a support rod, a stacking foot installed at the top of the support rod, and a stacking base installed at the bottom of the support rod. The height of the support rod is greater than the height of the support frame, and the support rod is set upward from the bottom of the support frame.

[0018] By designing the height of the support rods, stacking feet, and stacking base, stable stacking of multiple devices can be achieved, saving storage space and improving logistics efficiency.

[0019] Preferably, to enhance stability and guidance during stacking, the stacking feet have an isosceles trapezoidal cross-section. By setting the stacking feet with an isosceles trapezoidal cross-section, self-positioning and anti-slip properties are achieved during stacking, ensuring the safety of high-level stacking and facilitating stacking guidance.

[0020] Preferably, to facilitate mechanized handling operations, the support frame is provided with a longitudinally continuous transfer slot. This longitudinally continuous transfer slot on the support frame enables forklifts or AGVs to quickly insert and move, improving the efficiency and convenience of the transfer process.

[0021] Beneficial Effects: This utility model utilizes a rectangular support frame and multiple sets of spaced horizontal / vertical limiting blocks to form a four-way abutment constraint structure for the battery pack, significantly improving its resistance to displacement and slippage under dynamic operating conditions. Simultaneously, the optimized limiting block layout design preserves ample operating space at the bottom of the battery pack, effectively improving the gripping smoothness of automated tools such as material handling grippers. Furthermore, the L-shaped three-dimensional limiting design with limiting protrusions strengthens the horizontal constraint rigidity, and combined with guide ramps, achieves self-correction during hoisting, reducing the risk of collisions. The sliding adjustment mechanism of grooved profiles and sliders improves the stepless adjustment convenience of the limiting block positions, meeting the rapid adaptation needs of various battery pack specifications. Relying on the trapezoidal stacking feet of the stacking components and the through-slot design of the support frame, the stacking stability of the transfer device and the efficiency of mechanized handling are effectively improved, meeting the requirements of efficient turnover and space-saving in production, storage, and transportation.

[0029] like Figure 1 As shown,

[0030] A convenient battery pack transfer device includes a support frame 1, which is a rectangular support frame made of square tubes. Lateral limiting blocks 2 and longitudinal limiting blocks 3 are respectively installed on the square tubes on both sides of the support frame 1. At least one set of lateral limiting blocks 2 are arranged in pairs on the square tubes on both sides of the support frame 1, and two sets of longitudinal limiting blocks 3 are arranged in pairs on the square tubes on both sides of the support frame 1. The longitudinal limiting blocks 3 on each side of the square tubes on the lateral side of the support frame 1 are located on both sides of the lateral limiting blocks 2. Adjacent lateral limiting blocks 2 on each side of the square tubes on the lateral side of the support frame 1 are spaced apart, and longitudinal limiting blocks 3 are spaced apart from lateral limiting blocks 2. The lateral limiting blocks 2 on each side of the square tubes on the lateral side of the support frame 1 are arranged opposite each other laterally along the support frame 1, and the longitudinal limiting blocks 3 on each side of the square tubes on the lateral side of the support frame 1 are arranged opposite each other longitudinally along the support frame 1. The two lateral end faces of the battery pack abut against the lateral limiting blocks 2 on the square tubes on both sides of the support frame 1, and the two longitudinal end faces of the battery pack abut against the two sets of longitudinal limiting blocks 3.

[0031] A rectangular support frame composed of square tubes is used, with lateral limiting blocks 2 and longitudinal limiting blocks 3 grouped on the lateral sides of the square tubes. The limiting blocks are arranged at intervals, so that the lateral end faces of the battery pack abut against the lateral limiting blocks 2 and the longitudinal end faces abut against the longitudinal limiting blocks 3, forming a multi-directional constraint structure. This solves the risk of displacement and slippage caused by insufficient constraint on the battery pack in existing devices under dynamic operating conditions. At the same time, the interval design retains operating space at the bottom of the battery pack, providing gripping space for the material distribution gripper, thus balancing stability and ease of operation.

[0032] To limit the displacement of the battery pack in four directions, a limiting protrusion 4 is provided extending upward from the side end of the transverse limiting block 2 and protruding from the upper surface of the transverse limiting block 2. The limiting protrusion 4 is perpendicular to the upper surface of the transverse limiting block 2. The transverse limiting block 2 and the longitudinal limiting block 3 have the same structure, and the limiting protrusions 4 of the transverse limiting block 2 and the longitudinal limiting block 3 are perpendicular to each other. The bottom surface of the battery pack abuts against the upper surfaces of the transverse limiting block 2 and the longitudinal limiting block 3, and the two transverse end faces of the battery pack abut against the limiting protrusions 4 of the transverse limiting block 2 and the longitudinal limiting block 3, respectively.

[0033] By extending the limiting protrusions 4 upward from the side surfaces of the transverse limiting block 2 and the longitudinal limiting block 3, the bottom surface of the battery pack is in contact with the upper surface of the limiting block, and the side surface is in contact with the limiting protrusions 4, thus realizing an L-shaped three-dimensional limiting structure, which significantly enhances the rigid constraint on the horizontal direction of the battery pack.

[0034] In order to serve as a guide during the hoisting of the battery pack, the limiting protrusion 4 is provided with a guide ramp 5 on the surface that abuts against the battery pack.

[0035] By setting a guide ramp 5 between the limiting protrusion 4 and the contact surface of the battery pack, the battery pack can achieve self-correction positioning during the falling process, avoiding collision damage caused by position deviation and improving hoisting efficiency and safety.

[0036] To avoid frequent drilling on the square tubes and to make them adaptable to different battery pack sizes, a grooved profile 6 is also included on the square tubes on both sides of the support frame 1. The grooved profile 6 is disposed between the horizontal square tubes of the support frame 1 and the horizontal limiting block 2 and the vertical limiting block 3. The horizontal limiting block 2 and the vertical limiting block 3 are slidably connected to the grooved profile 6 through a moving component.

[0037] By adding a grooved profile 6 and a moving component, the horizontal / vertical limiting block 3 is slidably connected to the profile, realizing stepless adjustment of the position of the limiting block. It can quickly match various battery pack specifications simply by moving along the groove.

[0038] To simplify the adjustment process of the limiting block position, the moving component includes a slider 7, which matches the groove of the grooved profile 6. The transverse limiting block 2 and the longitudinal limiting block 3 are respectively provided with the same first through hole 8 along the vertical direction. The slider 7 is provided with a second through hole 71 that matches the first through hole 8. The transverse limiting block 2 and the longitudinal limiting block 3 are respectively connected to the slider 7 by bolts passing through the first through hole 8 and the second through hole 71.

[0039] By using the slider 7 to cooperate with the slot and by using bolts to pass through the through holes of the limiting block and the slider 7 to achieve a detachable connection, the slider 7 and the limiting block can be moved synchronously after the bolts are loosened and then fixed after tightening, which greatly improves the adjustment efficiency.

[0040] In order to facilitate the installation of the grooved profile 6 and improve the reliability and load-bearing capacity of the installation, an installation plate 9 is also included, which is symmetrically arranged along the vertical center line of the longitudinal square tube of the support frame 1. The installation plate 9 is arranged between the longitudinal square tube of the support frame 1 and the grooved profile (6). The bottom surface of the installation plate 9 is fixedly connected to the upper surface of the longitudinal square tube of the support frame 1, and the top surface of the installation plate 9 is connected to the bottom surface of the grooved profile 6.

[0041] To facilitate the stacking, storage, and transportation of the transfer device, a stacking assembly 10 is also included, which is installed on square tubes at both ends of the support frame 1. The stacking assembly 10 includes a support rod 101, a stacking foot 102 installed at the top of the support rod 101, and a stacking base 103 installed at the bottom of the support rod 101. The height of the support rod 101 is greater than the height of the support frame 1, and the support rod 101 is set upward from the bottom of the support frame 1.

[0042] By designing the heights of the support rod 101, stacking feet 102, and stacking base 103, stable stacking of multiple devices can be achieved, saving storage space and improving logistics efficiency.

[0043] To enhance stability and guidance during stacking, the cross-section of the stacking foot 102 is an isosceles trapezoid.

[0044] By setting stacking feet 102 with an isosceles trapezoidal cross-section, self-positioning and anti-slip are achieved during the stacking process, ensuring the safety of high-level stacking and facilitating stacking guidance.

[0045] To facilitate mechanized handling, the support frame 1 is provided with a longitudinally penetrating transfer groove 11.

[0046] By setting a through transfer channel 11 longitudinally through the support frame 1, forklifts or AGVs can be quickly inserted and moved, improving the efficiency and convenience of the transfer process.
