Description

Technical Field

[0001] This utility model relates to the field of material transportation technology, specifically a square battery cell material transfer trolley. Background Technology

[0002] Against the backdrop of the rapid development of the new energy industry, prismatic cells, as a core component of power batteries, directly impact the overall production rhythm through efficient and safe material handling during their production, storage, and assembly. Currently, short-distance transport of prismatic cells largely relies on traditional trolleys or simple turnover devices. The moving parts of existing transport tools (such as casters) generally lack targeted anti-slip limiting structures. When the workshop floor is sloping or requires uphill transport, the vehicle is prone to backing up due to the weight of the cells, increasing the difficulty of control for operators and potentially leading to cell collisions, slippage, or even safety accidents. While some equipment is equipped with braking mechanisms, these are mostly passive designs that directly lock the wheels, failing to achieve unidirectional protection that "allows forward movement but restricts reverse movement," resulting in insufficient flexibility and safety. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a square battery cell material transfer trolley with the advantage of unidirectional anti-slip, solving the problem of traditional transfer trolleys easily backing uphill.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A square battery cell material transfer trolley includes an aluminum profile frame serving as the carrier of the entire device and a base fixed to the aluminum profile frame for placing the battery cells. Casters are installed at the four corners of the bottom of the aluminum profile frame, and an anti-slip mechanism is provided to prevent the casters from rotating. The anti-slip mechanism includes a connecting shaft fixed to the casters, a transmission wheel fixed to the connecting shaft, a plurality of inclined blocks I hinged to the transmission wheel, a spring fixed between the inclined blocks I and the transmission wheel, and a ring movably installed next to the transmission wheel, with a plurality of inclined blocks II fixed to the inner wall of the ring.

[0005] Preferably, both sides of the aluminum profile frame are provided with cavities, and a bidirectional lead screw is rotatably installed in the cavity. A transmission bar is threaded to both sides of the bidirectional lead screw, and the transmission bar extends to the bottom of the aluminum profile frame through a sliding groove. The bottom end of the transmission bar is fixedly connected to a nearby ring.

[0006] Preferably, the tilt angles of the first and second inclined blocks are both 30°-45°, and the number of the first and second inclined blocks is equal and corresponds one-to-one.

[0007] Preferably, a worm gear is mounted on the bidirectional lead screw, a rotating shaft is rotatably mounted on the aluminum profile frame, a worm gear that meshes with the worm gear is mounted on the rotating shaft, and a handwheel is fixedly connected to the rotating shaft.

[0008] Preferably, a handrail is fixed to the aluminum profile frame, and an anti-slip grip is provided on the outer periphery of the handwheel. The surface of the anti-slip grip is covered with a rubber layer, and the handwheel is provided with scale lines for indicating the locked state.

[0009] Preferably, the top of the base is provided with a plurality of spaced limiting strips, which extend along the length of the aluminum profile frame, and adjacent limiting strips enclose to form a placement groove adapted to the square battery cell.

[0010] By employing the above technical solution, this utility model provides a square battery cell material transfer trolley, which has at least the following beneficial effects: 1. This square battery cell material transfer trolley, through the setting of an anti-slip mechanism, realizes the one-way limit function of "smooth forward rotation and locked reverse rotation" of the casters, which can effectively prevent the trolley from rolling backward when going uphill. At the same time, the anti-slip status of the four casters can be controlled synchronously through a single operating terminal, which improves the safety and efficiency of the transfer.

[0011] 2. This square battery cell material transfer trolley, by setting a limit strip on the top of the base, a handle on the aluminum profile frame, and a handwheel with anti-slip grips and scale lines, not only achieves orderly positioning and anti-collision protection of square battery cells, but also improves the convenience of trolley operation and the accuracy of anti-slip mechanism control, making it suitable for batch battery cell transfer scenarios.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a square battery cell material transfer trolley.

[0016] Example 1: Combination Figures 1-4 As shown, the present invention provides a square battery cell material transfer trolley, including an aluminum profile frame 100 as the carrier of the entire device and a base 101 fixed to the aluminum profile frame 100 for placing the battery cells. The platform on the base 101 has an adjustment function and can be used for the transfer of square battery cells of various specifications. It has strong versatility and is suitable for small-batch material transfer by trial production personnel. Casters 103 are installed at the four corners of the bottom of the aluminum profile frame 100, and an anti-slip mechanism 200 is also provided to prevent the casters 103 from rotating. This ensures smooth passage when turning forward on an incline and can quickly lock the transmission wheel 205 when turning backward, effectively reducing the backward speed and improving the safety of the transfer. The anti-slip mechanism 200 includes a connecting shaft 206 fixed to the caster 103, a drive wheel 205 fixed to the connecting shaft 206, a plurality of inclined blocks 208 hinged to the drive wheel 205, a spring 207 fixed between the inclined blocks 208 and the drive wheel 205, and a ring 204 movably mounted next to the drive wheel 205. A plurality of inclined blocks 209 are fixed to the inner wall of the ring 204. When going uphill, the ring 204 is moved so that the inclined blocks 209 on the ring 204 are directly above the inclined blocks 208. Then, when the caster 103 rotates clockwise, the caster 103 drives the drive wheel 205. When the 05 rotates, the first inclined block 208 rotates with the transmission wheel 205. When it comes into contact with the second inclined block 209, the spring 207 is compressed, allowing it to rotate normally. When the caster 103 reverses, the first inclined block 208 comes into contact with the second inclined block 209, locking the first inclined block 208. Consequently, the transmission wheel 205 cannot reverse, preventing the caster 103 from reversing as well. This reduces the speed of the vehicle moving backwards when going uphill. Furthermore, a single rotation allows the transmission bars 203 on both sides to move synchronously in opposite directions, thereby driving the rings 204 on both sides to switch positions synchronously, ensuring the consistency of the anti-slip mechanisms 200 on both sides.

[0017] Specifically, the aluminum profile frame 100 has cavities 201 on both sides. A bidirectional lead screw 202 is rotatably installed in the cavity 201. A transmission bar 203 is threaded to both sides of the bidirectional lead screw 202. The transmission bar 203 extends to the bottom of the aluminum profile frame 100 through a sliding groove. The bottom end of the transmission bar 203 is fixed to a nearby ring 204. The rotation of the bidirectional lead screw 202 causes the transmission bars 203 on both sides to move in opposite directions, and the ring 204 moves with the transmission bar 203.

[0018] Furthermore, the tilt angles of both the first inclined block 208 and the second inclined block 209 are 30°-45°. If the angle is too small, it will easily lead to insufficient clamping force when reversing, while if the angle is too large, it will increase the compression resistance of the spring 207 when rotating forward. The number of the first inclined block 208 and the number of the second inclined block 209 are equal and correspond one-to-one to avoid anti-slip failure due to misalignment, ensure the comprehensiveness and stability of the anti-slip mechanism 200, and improve the reliability of the one-way locking function.

[0019] A worm gear 210 is mounted on the double-acting lead screw 202. A rotating shaft 211 is rotatably mounted on the aluminum profile frame 100. A worm 212 that meshes with the worm gear 210 is mounted on the rotating shaft 211. A handwheel 213 is fixedly connected to the rotating shaft 211. Rotating the handwheel 213 drives the rotating shaft 211 to rotate. The worm 212 rotates with the rotating shaft 211. The worm 212 drives the double-acting lead screw 202 to rotate through the worm gear 210. Thus, the four casters 103 can be anti-slip simultaneously through the linkage structure.

[0020] As can be seen from the embodiments, there is no need to adjust each caster 103 individually, which greatly improves the operating efficiency. At the same time, the self-locking characteristics of the worm gear 210 and worm 212 can maintain the locked state, avoiding safety hazards caused by accidental unlocking.

[0021] Example 2: Combination Figure 1 and Figure 2 As shown, based on Embodiment 1, a handrail 102 is fixedly attached to the aluminum profile frame 100, and an anti-slip handle is provided on the outer periphery of the handwheel 213. The surface of the anti-slip handle is covered with a rubber layer to increase friction and prevent hand slippage during operation, ensuring precise control of the anti-slip mechanism 200. The handwheel 213 is provided with scale lines for indicating the locked state, which can intuitively display the working status (locked or unlocked) of the anti-slip mechanism 200.

[0022] Specifically, the base 101 has multiple spaced limiting strips on its top. The limiting strips extend along the length of the aluminum profile frame 100. Adjacent limiting strips enclose and form a placement groove that fits the square battery cell. This allows for precise positioning and limiting of the battery cell, effectively preventing displacement, tipping, or collision of the battery cell during transportation, and reducing the risk of damage to the battery cell's appearance or performance.

[0023] As can be seen from the above embodiments: the square battery cell to be transported is placed into the fitting slot formed by adjacent limiting strips on the top of the base 101 to ensure stable placement of the battery cell; then, the operator holds the handle on the aluminum profile frame 100 to push the trolley to move. When it is necessary to go uphill, the operator turns the handwheel 213, which drives the rotating shaft 211 to rotate. The worm gear 212 on the rotating shaft 211 meshes with the worm wheel 210 on the bidirectional lead screw 202, causing the bidirectional lead screw 202 to rotate in the cavities 201 on both sides of the aluminum profile frame 100. The transmission bars 203 threaded on both sides of the bidirectional lead screw 202 move in opposite directions and extend to the bottom of the frame through the slide groove. The transmission bars 203 drive the ring 204 fixed at the bottom to move until the scale line of the handwheel 213 shows the locked state. At this time, the inclined block 209 on the inner wall of the ring 204 moves to the inclined block on the transmission wheel 205. Directly above 208, the anti-slip mechanism 200 is activated. During the uphill process, when the caster 103 rotates forward, it drives the transmission wheel 205 on the connecting shaft 206 to rotate. When the first inclined block 208 contacts the second inclined block 209, the spring 207 is compressed, and the caster 103 rotates normally. If the caster 103 has a tendency to reverse, the first inclined block 208 and the second inclined block 209 will be locked after contact, and the transmission wheel 205 will not be able to reverse, thus preventing the caster 103 from reversing and reducing the backward speed of the vehicle. After the uphill is completed, the handwheel 213 is rotated in the opposite direction, which drives the ring 204 to reset through the worm gear 210, worm 212, double lead screw 202, and transmission bar 203, so that the second inclined block 209 separates from the first inclined block 208 and releases the anti-slip lock. After pushing the trolley to the target position, the square battery cell placed in the slot is taken out smoothly. After the transfer is completed, the condition of each part of the trolley is checked again to ensure that there is no damage before it is properly parked.
