Description

Technical Field

[0001] This utility model relates to the field of new energy vehicle battery production technology, and in particular to a new energy vehicle battery bracket. Background Technology

[0002] New energy vehicle battery trays are used to support and position battery packs during assembly, testing, and logistics transportation on production lines, ensuring stable positioning and precise docking, and are compatible with AGV automated handling systems. They also need to meet requirements such as rapid loading and unloading, high repeatability and positioning accuracy, structural impact resistance, and multi-layer stacking stability. They are key auxiliary tooling for achieving efficient, safe, and automated production and circulation of battery modules.

[0003] In existing technologies, traditional brackets mostly adopt fixed clamping structures, which lack a coarse and fine positioning coordination mechanism. When placing batteries, they cannot be automatically guided to center, and are prone to jamming or collision due to initial deviations. This not only reduces the assembly cycle time but also affects the repeatability of positioning accuracy. At the same time, rigid alignment is difficult to adapt to the tolerance fluctuations of different batches of batteries, resulting in poor loading and unloading efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a battery bracket for new energy vehicles to solve the problem of battery placement jamming caused by the use of a fixed clamping structure and the lack of a coarse and fine positioning coordination mechanism in traditional brackets mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a new energy vehicle battery bracket, including a bearing component, the bearing component including a bearing block, a support block integrally formed on the bearing block, an adhesive plate on the support block, and a plurality of support legs at the bottom of the bearing block. The adhesive plate is used to support the battery body, and a positioning post is provided on the adhesive plate. The support legs are provided with positioning holes corresponding to the positioning posts. An inlet opening can be formed between two support legs. The inlet opening is used to unload force from accidental impacts by the AGV. A first positioning component is provided on both sides of the adhesive plate, and a second positioning component is provided below the adhesive plate.

[0006] In a preferred embodiment of this technical solution, the second positioning component includes a perforation formed on the bonding plate, a round rod inside the perforation, a mounting block provided on the side wall of the battery body, and a mounting hole provided on the mounting block, through which the round rod can be inserted.

[0007] Based on the preferred embodiment of this technical solution, the top of the round rod is integrally formed with a guide cone, which is used to correct the placement deviation of the battery body.

[0008] Based on the preferred embodiment of this technical solution, a second limiting block is integrally formed at the outer diameter of the round rod. The second limiting block can fit onto the bearing block. A second spring is sleeved between the round rod and the fitting plate and the second limiting block. A connecting plate is spirally connected to the bottom of the round rod, and the connecting plate can contact the AGV lifting plate.

[0009] According to the preferred embodiment of this technical solution, the first positioning component includes mounting positions opened on both sides of the bonding plate and an L-shaped block rotatably connected within the mounting positions. The L-shaped block includes a first plate and a second plate. When the second plate is bonded to the bottom of the battery body, the first plate can bond to the side wall of the battery body.

[0010] In a preferred embodiment of this technical solution, a U-shaped block is provided below the bonding plate. The U-shaped block can simultaneously abut against the second plate of the L-shaped blocks on both sides to form an opening space for accommodating the battery body.

[0011] In the preferred embodiment of this technical solution, a guide rod is spirally connected to the bottom of the bonding plate, and a first limiting block is spirally connected to the guide rod. A first spring is sleeved between the guide rod and the corresponding U-shaped block and the first limiting block. The first spring is used to drive the U-shaped block to abut against the second plate.

[0012] In a preferred embodiment of this technical solution, the first positioning component includes a dovetail groove on the bottom of a plate and a bidirectional screw rotatably connected to a bearing block. A dovetail block corresponding to the dovetail groove is provided on the second plate. The rotation of the bidirectional screw can drive the L-shaped blocks on both sides to move towards each other. A handwheel for driving the bidirectional screw to rotate is installed on the bearing block.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. By using L-shaped blocks and U-shaped blocks together, lateral coarse positioning is achieved, and space is reserved for insertion to avoid interference and jamming when the battery is placed, which significantly improves the smoothness of placement and the safety of operation.

[0014] 2. A precision positioning assembly consisting of a guide cone and a retractable round rod is used, combined with the AGV lifting triggering mechanism, to automatically correct residual deviations and ensure high repeatability and reliable handling. Attached Figure Description

[0017] 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.

[0018] Please see Figure 1-6 This utility model provides an embodiment of a new energy vehicle battery bracket, including a support component 1. The support component 1 includes a support block 10, a support block 12 integrally formed on the support block 10, an adhesive plate 13 on the support block 12, and several support legs 11 at the bottom of the support block 10. The adhesive plate 13 supports the battery body 5 and has positioning posts 131. The support legs 11 have positioning holes corresponding to the positioning posts 131. An inlet opening 110 can be formed between two support legs 11 to relieve force from accidental impacts by AGVs. First positioning components 2 are provided on both sides of the adhesive plate 13, and a second positioning component 4 is provided below the adhesive plate 13. This overall structure integrates multi-level positioning, avoidance, AGV compatibility, and stacking stability functions, meeting the high-precision assembly requirements of production lines while also considering logistics handling efficiency and structural protection under abnormal working conditions, significantly improving the bracket's versatility and safety.

[0019] Please see Figure 1-6 A further solution based on this embodiment is as follows: the second positioning component 4 includes a through hole 133 formed on the bonding plate 13 and a round rod 41 inside the through hole 133. A mounting block 51 is provided on the side wall of the battery body 5, and a mounting hole 511 is formed on the mounting block 51, through which the round rod 41 can pass. Through the cooperation of the round rod 41 and the mounting hole 511, precise positioning of the battery body 5 in the horizontal plane is achieved, effectively limiting its lateral displacement and improving assembly repeatability.

[0020] Please see Figure 4-5A further solution based on this embodiment is as follows: a guide cone 411 is integrally formed on the top of the round rod 41. The guide cone 411 is used to correct the placement deviation of the battery body 5. The setting of the guide cone 411 significantly improves the alignment tolerance between the round rod 41 and the mounting hole 511. Even if there is a slight offset when the battery is lowered, it can automatically slide into the mating position under its own weight, reducing the need for manual intervention and improving work efficiency.

[0021] Please see Figure 4-5 A further embodiment of this solution is as follows: a second limiting block 412 is integrally formed at the outer diameter of the round rod 41. The second limiting block 412 can fit against the bearing block 10. A second spring 44 is sleeved between the round rod 41 and the fitting plate 13 and the second limiting block 412. A connecting plate 43 is spirally connected to the bottom of the round rod 41, and the connecting plate 43 can contact the AGV lifting plate. This elastic and retractable structure allows the round rod 41 to automatically retract under normal conditions and be pushed out when the AGV is lifted, achieving precise alignment.

[0022] Please see Figure 2-3 A further solution based on this embodiment is as follows: The first positioning component 2 includes mounting positions 130 on both sides of the bonding plate 13 and an L-shaped block 21 rotatably connected within the mounting positions 130. The L-shaped block 21 includes a first plate 211 and a second plate 212. When the second plate 212 is attached to the bottom of the battery body 5, the first plate 211 can be attached to the side wall of the battery body 5. The L-shaped block 21 adopts a passive swing design, automatically attaching to the side wall and bottom edge during the battery placement process, realizing the first rough alignment work.

[0023] Please see Figure 2-3 A further solution based on this embodiment is as follows: A U-shaped block 22 is provided below the bonding plate 13. The U-shaped block 22 can simultaneously abut against the second plate 212 of the L-shaped blocks 21 on both sides to form an opening space for accommodating the battery body 5. Before the battery is placed, the U-shaped block 22 expands the L-shaped blocks 21 to an open state, leaving sufficient space for insertion, effectively preventing the first plate 211 from blocking the battery too early, ensuring that the battery can be placed smoothly without obstacles, and improving the safety of human-machine operation.

[0024] Please see Figure 2-4 A further embodiment of this solution is as follows: a guide rod 231 is spirally connected to the bottom of the bonding plate 13, and a first limiting block 232 is spirally connected to the guide rod 231. A first spring 233 is sleeved between the guide rod 231 and the corresponding U-shaped block 22 and the first limiting block 232. The first spring 233 is used to drive the U-shaped block 22 to abut against the second plate 212. The spring-driven U-shaped block 22 has a simple and reliable structure, can maintain the pre-opened state of the L-shaped block 21 without external power, and also has a buffering capacity.

[0025] The second embodiment of the first positioning component 2, please refer to [link / reference]. Figure 6 A further solution based on this embodiment is as follows: The first positioning component 2 includes a dovetail groove at the bottom of the bonding plate 13 and a bidirectional screw 61 rotatably connected to the bearing block 10. The second plate 212 is provided with a dovetail block corresponding to the dovetail groove. The rotation of the bidirectional screw 61 can drive the L-shaped blocks 21 on both sides to move towards each other. A handwheel 62 for driving the bidirectional screw 61 to rotate is installed on the bearing block 10. This manually adjustable structure is suitable for high-precision lateral clamping scenarios. The distance between the L-shaped blocks 21 on both sides can be adjusted synchronously by the handwheel 62, achieving rapid adaptation and locking by utilizing the self-locking property of the screw.

[0026] Working principle: When the battery body 5 is hoisted and lowered above the bracket, it is first roughly positioned by the L-shaped blocks 21 on both sides, which are in an open state. The L-shaped blocks 21 are pre-opened under the action of the U-shaped blocks 22 and the first spring 233, forming a lateral guide opening 110 larger than the battery's shape, ensuring that the battery can enter smoothly. As the battery continues to fall, its bottom contacts the second plate 212 of the L-shaped blocks 21, causing the L-shaped blocks 21 to rotate around the mounting position 130, so that the first plate 211 automatically fits against the side wall of the battery, completing the lateral (left-right) coarse centering. It should be noted that this solution does not have a dedicated longitudinal (front-back) coarse positioning structure because the battery body 5 is a long strip component. During hoisting and placement, the main cause of significant lateral positional deviation is the swing, while the longitudinal deviation is usually smaller. The battery is long, and the displacement caused by a small angle deflection in the longitudinal direction is much smaller than that in the lateral direction. Meanwhile, the subsequent second positioning component 4 (round rod 41 and guide cone 411) has sufficient tolerance to automatically correct longitudinal deviations within this range, thus eliminating the need for an additional longitudinal coarse positioning structure. Subsequently, during the battery's complete placement, the AGV lifts and pushes the connecting plate 43, overcoming the elasticity of the second spring 44, pushing the originally retracted round rod 41 upwards, allowing the guide cone 411 at its top to insert into the mounting hole 511 of the battery sidewall mounting block 51, achieving precise positioning. The conical structure of the guide cone 411 further corrects residual deviations in the lateral and longitudinal directions, ensuring high repeatability positioning accuracy. When the AGV completes lifting and transporting the tray, the round rod 41 remains extended to maintain positioning. After the tray reaches the next workstation and is lowered, the AGV withdraws, and the second spring 44 drives the round rod 41 to automatically retract, releasing the constraint. This design, through a collaborative mechanism of "lateral coarse positioning + omnidirectional fine positioning," balances placement smoothness and positioning accuracy. In the second embodiment: the first positioning component 2 adopts an active adjustment structure, including a bidirectional screw 61 rotatably connected to the bearing block 10, a dovetail groove at the bottom of the bonding plate 13, and a dovetail block on the second plate 212 of the L-shaped block 21; the operator can rotate the bidirectional screw 61 through the handwheel 62 to drive the two L-shaped blocks 21 on both sides to move synchronously towards or away from each other along the dovetail groove, thereby precisely adjusting the distance between the first plates 211. The AGV is a transport trolley.
