Description

Technical Field

[0001] This utility model relates to the field of battery conveying mechanism technology, specifically to a limiting device for a battery rack. Background Technology

[0002] In the production, testing, and transportation of lithium-ion batteries, power batteries, and other products, battery racks serve as crucial carriers and positioning fixtures, widely used in automated production lines, laboratories, and warehousing logistics. During transfer, batteries require racks for stable storage and precise positioning to ensure they are protected from damage by collisions, vibrations, and other external forces during loading, unloading, charging / discharging testing, and handling, while also meeting the repeatability and accuracy requirements of automated equipment. Therefore, the structural design and performance of the racks directly impact the safety, efficiency, and smoothness of battery handling and the overall production process.

[0003] Currently, common battery transport racks in the industry typically employ a frame structure, primarily constructed from welded or assembled metal profiles (such as aluminum profiles or steel square tubing) to provide sufficient structural strength. Inside the rack, a series of fixed limiting and protective structures are installed to accommodate the specific dimensions of each battery model. These structures usually include welded or bolted limiting blocks and rods, as well as protective padding formed by cushioning materials such as foam and EVA. After the batteries are placed in the rack, the combination of these rigid limiting mechanisms and flexible cushioning achieves circumferential and bottom-level restraint, thus precisely fixing them in space and preventing them from shifting or colliding with each other inside the rack.

[0004] However, the existing battery transport racks have a significant drawback: their internal positioning and clamping devices are designed and manufactured for a single, fixed battery specification. This means that a rack can typically only accommodate one specific battery model. In actual production, especially in flexible manufacturing models with multiple varieties and small batches, battery manufacturers or users often need to handle multiple batteries of different sizes simultaneously. This necessitates the use of multiple dedicated racks for corresponding specifications, which not only significantly increases tooling costs and occupies a large amount of warehousing and logistics space, but also makes rack switching during production line changes cumbersome, reducing overall operational efficiency. Furthermore, for batteries that are similar but not identical in size, using fixed-size racks either fails to reliably secure them, posing a safety hazard, or results in wasted space and insufficient protection due to excessive gaps. Utility Model Content

[0005] The present invention aims to provide a limiting device for battery racks to solve the problem that the fixed size of existing battery racks necessitates the replacement of the entire rack when transporting or storing batteries of different sizes.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A limiting device for a battery rack includes multiple first limiting units and second limiting units. Each first limiting unit is symmetrically installed on opposite sides of the rack, and the second limiting units are symmetrically installed on the other two sides of the rack. Each first limiting unit includes a first adjusting groove and a first limiting member. The first limiting member is slidably connected to the first adjusting groove via a slider, and the first adjusting groove is slidably connected to the rack. Each second limiting unit includes a second adjusting groove and a second limiting member. The second limiting member is slidably connected to the second adjusting groove via a slider, and the second adjusting groove is fixedly connected to the rack. Adjustment mechanisms are provided at the sliding connections between the slider and both the first and second adjusting grooves. The first and second limiting members together form a receiving hole for installing batteries.

[0007] Beneficial effects: 1. By incorporating a first limiting unit that can slide and adjust on both sides of the rack, and a second limiting unit that can be finely adjusted on the other two sides, the device can dynamically change the size of the receiving hole formed by the first and second limiting units. This allows a single rack to accommodate batteries of various sizes and specifications, achieving compatibility of one rack with multiple battery models. This significantly improves the rack's versatility and effectively solves the problem of needing to replace or re-customize the entire rack due to changes in battery models, thereby reducing equipment purchase costs and the complexity of warehouse management.

[0008] 2. Each slider is equipped with an adjustment mechanism at the connection point with the adjustment groove. Once the position of the limiting component is adjusted, it can be firmly locked by the mechanism to ensure that the limiting device will not shift due to vibration or impact during subsequent handling and transportation. This provides stable and reliable clamping and protection for the battery, avoiding safety risks such as battery loosening and collision that may occur due to the use of a fixed rack with poor compatibility.

[0009] Preferably, as an improvement, the adjustment mechanism includes a housing and two sets of adjustment units that slide in opposite directions on the housing. The housing is fixed on the slider, and the adjustment units are used to engage with the first adjustment slot or the second adjustment slot.

[0010] Beneficial effects: By integrating two sets of opposing adjustment units into a housing that passes through the slider, this design achieves synchronous locking and releasing on both sides of the adjustment groove, ensuring that the slider is subjected to balanced force when locked, avoiding swaying or loosening that may be caused by locking on one side, thereby greatly improving the stability and reliability of the limiting component under load and vibration.

[0011] Preferably, as an improvement, the adjustment unit includes an adjustment block, a moving rod, a spring, and a baffle. The adjustment block and the moving rod are integrally formed. The end of the adjustment block away from the moving rod is inserted into an adjustment hole provided on the side wall of the first adjustment groove. The moving rod is slidably connected in the housing. The baffle is fixedly connected in the housing. One end of the elastic element is fixedly connected to the adjustment block, and the other end abuts against the baffle.

[0012] Beneficial effects: The integrated design of the adjusting block and the moving rod enhances structural strength and simplifies assembly. The adjusting block is directly inserted into the adjusting hole to achieve rigid mechanical interlocking, while the spring provides continuous locking force and allows the mechanism to automatically reset after unlocking. This enables a quick and easy operation experience of pressing to unlock and releasing to lock, while ensuring absolute reliability of the locked state when no external force is involved.

[0013] Preferably, as an improvement, the end face of the adjusting block away from the moving rod is wedge-shaped.

[0014] Beneficial effects: By designing the end of the adjusting block as a wedge-shaped surface, the smoothness and fault tolerance of the locking process are greatly optimized.

[0015] Preferably, as an improvement, the adjustment unit further includes an adjustment rod, and a strip-shaped hole is provided on the top of the housing, through which the adjustment rod is detachably connected to the moving rod.

[0016] Beneficial effects: The adjusting rod connects to the moving rod through the slotted hole on the housing, providing the operator with a clear and effortless point of application. By simply pinching the two adjusting rods inward, both adjusting units can be unlocked simultaneously, enabling quick, tool-free adjustment and greatly improving operational efficiency.

[0017] Preferably, as an improvement, the first adjusting groove is provided with guide rails at both ends, the guide rails are mounted on the material rack, the first adjusting groove can slide along the length of the guide rails, and a locking mechanism is provided at the sliding connection.

[0018] Beneficial effects: By allowing the entire first adjustment groove to slide along the guide rail, the spacing between the limiting members on both sides of the material rack can be adjusted over a wide range to accommodate significant differences in battery width; combined with the adjustment of the limiting members in the length direction within the first adjustment groove, the limiting device can cover a wider range of battery sizes, further enhancing its flexibility and adaptability.

[0019] Preferably, as an improvement, the locking mechanism includes a handle, a locking rod, and a locking element. One end of the locking rod passes through the guide rail and is threadedly connected to the locking element via the first adjusting groove, while the other end is connected to an eccentric wheel provided on the handle.

[0020] Beneficial effects: Utilizing the principle of an eccentric wheel, rotating the handle allows the locking rod to quickly tighten or loosen the guide rail, achieving a one-turn lock and one-turn release effect. Compared to traditional bolt locking methods that require multiple rotations, this locking mechanism operates extremely quickly, saving time and effort, further enhancing its advantages in rapid changeover scenarios.

[0021] Preferably, as an improvement, the locking mechanism further includes a connecting seat, which is installed in the first adjusting groove, and the locking rod passes through the connecting seat and connects to the locking member. The end face of the connecting seat near the handle is arc-shaped.

[0022] Beneficial effects: As a force-bearing component, the connecting seat can distribute the locking force and protect the first adjustment groove body from damage. Its end face near the handle is designed as an arc, providing a smooth contact surface for the rotation of the eccentric wheel, ensuring that the handle can rotate smoothly within the locking stroke, avoiding jamming, resulting in a better operating feel and improving the durability of the mechanism.

[0023] Preferably, as an improvement, an auxiliary component is provided at the sliding connection between the first adjusting groove and the guide rail. The auxiliary component includes a rolling bearing, a bolt, and a nut. The bolt passes through the rolling bearing and is connected to the nut. The rolling bearing is located inside the guide rail.

[0024] Beneficial effects: By setting rolling bearings, the original sliding friction is transformed into rolling friction, making it easier and less strenuous to push the heavy first adjusting groove, reducing the wear of the guide rail and adjusting groove, and extending the service life of the entire device.

[0025] Preferably, as an improvement, the first adjustment groove, the second adjustment groove, and the guide rail are all provided with marking sections.

[0026] Beneficial effects: Markings are set on the positions of the first adjustment slot, the second limit component, and the guide rail corresponding to different battery specifications, so that operators can quickly and accurately adjust each limit component to the predetermined position according to the markings.

Detailed Implementation

[0035] The following detailed description illustrates the specific implementation method: The basic implementation examples are as follows: Figures 1-7 As shown: like Figure 1 As shown, this embodiment provides a limiting device for a battery rack 1, including multiple first limiting units 3 and second limiting units 4. Each first limiting unit 3 is symmetrically installed on opposite sides of the rack 1, and the second limiting units 4 are symmetrically installed on the other two sides of the rack 1. The first limiting member 32 and the second limiting member 42 enclose a receiving hole for installing a battery. A support plate 2 for supporting the battery is provided inside the receiving hole, and the support plate 2 is installed in the middle of the rack 1. The first limiting unit 3 includes a first adjusting groove 31 and a first limiting member 32. The first limiting member 32 is slidably connected to the first adjusting groove 31 via a slider 5, and the first adjusting groove 31 is slidably connected to the rack 1. The second limiting unit 4 includes a second adjusting groove 41 and a second limiting member 42. The second limiting member 42 is slidably connected to the second adjusting groove 41 via a slider 5, and the second adjusting groove 41 is fixedly connected to the rack 1. Adjustment mechanisms 6 are provided at the sliding connections between the slider 5 and the first adjusting groove 31 and the second adjusting groove 41. It is worth noting that both the first limiting member 32 and the second limiting member 42 are made of rubber.

[0036] like Figure 2 As shown, the adjustment mechanism 6 includes a housing 61 and two sets of adjustment units that slide opposite each other on the housing. The housing 61 is fixed to the slider 5, and the adjustment units are used to engage with the first adjustment groove 31 or the second adjustment groove 41. Specifically, as shown... Figure 3 and Figure 4As shown, the adjustment unit includes an adjustment block 62, a moving rod 63, a spring, a baffle 65, and an adjustment rod 66. The adjustment block 62 and the moving rod 63 are integrally formed. The end of the adjustment block 62 away from the moving rod 63 is inserted into the adjustment hole 311 provided on the side wall of the first adjustment groove 31. To facilitate the insertion of the adjustment block 62 into the adjustment hole 311, the end face of the adjustment block 62 away from the moving rod 63 is wedge-shaped. The baffle 65 is fixedly connected inside the housing 61. One end of the elastic element 64 is fixedly connected to the adjustment block 62, and the other end abuts against the baffle 65. In this embodiment, the elastic element 64 is a spring. The movable rod 63 is slidably connected inside the housing 61. The top of the housing 61 is provided with a strip-shaped hole 611. The adjusting rod 66 passes through the strip-shaped hole 611 and is detachably connected to the movable rod 63. When an external force is applied to the adjusting rods 66 on both sides and they move closer to each other, the adjusting rods 66 can drive the movable rod 63 to move towards the center, thereby causing the adjusting block 62 to disengage from the adjusting hole 311, so as to adjust the position of the first limiting block. When the external force disappears, the adjusting rods 66 on both sides move away from each other, thereby causing the movable rod 63 to push the adjusting block 62 into the adjusting hole 311.

[0037] It is worth noting that the adjustment mechanism 6 in the second adjustment groove 41 is the same as the adjustment mechanism 6 in the first adjustment groove 31, so we will not go into too much detail here.

[0038] Furthermore, in order to adjust the first limiting member 32 along the width direction of the material rack 1, guide rails 7 are provided at both ends of the first adjusting groove 31. The guide rails 7 are installed on the material rack 1. The first adjusting groove 31 can slide along the length direction of the guide rails 7. A locking mechanism 8 is provided at the sliding connection.

[0039] Specifically, such as Figure 6 As shown, the locking mechanism 8 includes a handle 81, a locking rod 82, a locking element 83, and a connecting seat 84. The connecting seat 84 is installed in the first adjusting groove 31. One end of the locking rod 82 passes through the guide rail 7 of the connecting seat 84 and is threadedly connected to the first adjusting groove 31 and the locking element 83. The other end is connected to the eccentric wheel 811 provided on the handle 81. To facilitate the rotation of the eccentric wheel 811, the end face of the connecting seat 84 near the handle 81 is arc-shaped.

[0040] To facilitate the movement of the first adjusting groove 31 within the guide rail 7, in this embodiment, an auxiliary component 9 is also provided at the sliding connection between the first adjusting groove 31 and the guide rail 7, such as... Figure 7 As shown, the auxiliary component 9 includes a rolling bearing 91, a bolt 92, and a nut 93. The bolt 92 passes through the rolling bearing 91 and is connected to the nut 93. The rolling bearing 91 is located inside the guide rail 7.

[0041] The first adjustment groove 31, the second adjustment groove 41 and the guide rail 7 are all equipped with marking parts on the corresponding material rack 1, so that the operator can adjust the position of the first limit member 32 and the second limit member 42 in advance according to the size and specifications of the battery.

[0042] In actual use, the operator first determines the target positions of the first limiting member 32 and the second limiting member 42 based on the battery size specifications and the markings on the first adjusting groove 31, the second adjusting groove 41, and the guide rail 7 on the rack 1. Then, the battery is placed on the support plate 2, and the first limiting unit 3 and the second limiting unit 4 are adjusted sequentially according to the battery's fixed position, ensuring that the first limiting member 32 and the second limiting member 42 are fully abutted against the battery end face. For the first limiting unit 3, the operator rotates the handle 81 of the locking mechanism 8, causing the eccentric wheel 811 to drive the locking rod 82 away from the guide rail 7, thereby releasing the first adjusting groove 31. At this time, the first adjusting groove 31 can slide along the guide rail 7 to adjust the lateral position of the first limiting member 32. Then, the operator presses the adjusting rods 66 on both sides of the adjusting mechanism 6, causing the moving rod 63 to move inward, compressing the spring, and causing the adjusting block 62 to disengage from the adjusting hole 311 on the side wall of the first adjusting groove 31, thereby allowing the first limiting member 32 to slide and make fine adjustments along the length of the first adjusting groove 31. After adjustment, release the adjusting rod 66, the spring returns to its original deformation, pushing the adjusting block 62 back into the adjusting hole 311, fixing the first limiting member 32, and then tightening the locking mechanism 8 again to ensure the first adjusting groove 31 is stable. For the second limiting unit 4, since the second adjusting groove 41 is fixedly installed on the material rack 1, the operator only needs to operate the adjusting mechanism 6 similarly to adjust the position of the second limiting member 42 within the second adjusting groove 41.
