Description

Technical Field

[0001] This utility model relates to the field of battery loading technology, specifically to a battery tray. Background Technology

[0002] Currently, the production, storage, and transportation of cylindrical batteries commonly utilize one-piece injection-molded trays designed specifically for each battery size. This traditional tray design involves customizing a unique tray structure for each cylindrical battery with a specific diameter and height. However, with the rapid development of the lithium battery industry, the model specifications (especially diameter) of cylindrical batteries are being updated and iterated at an accelerated pace, exhibiting a trend towards diversification.

[0003] Traditional battery trays have fixed dimensions. Once the diameter or length of the battery changes, the original trays become unusable, failing to flexibly adapt to different battery sizes. This means that processing different battery models on the production line requires preparing and replacing multiple sets of trays of different specifications, resulting in cumbersome operations and difficulty in responding to rapidly changing market demands. Due to the lack of compatibility with different battery models, whenever a new battery model is introduced or customer requirements change, it is often necessary to redesign and manufacture entirely new tray molds and replace the entire inner lining structure of the tray. This not only significantly increases the company's mold development costs, material procurement costs, and inventory management costs, but also significantly prolongs the preparation cycle for new product introductions or production line switchovers, reducing overall production efficiency and economic benefits. Utility Model Content

[0004] In order to overcome the technical defects of existing technologies, such as the inability to flexibly accommodate batteries of different sizes and the low versatility of tray designs, this utility model provides a battery tray.

[0005] To solve the above problems, this utility model is implemented according to the following technical solution:

[0006] The present invention provides a battery tray for loading cylindrical batteries, comprising:

[0007] The tray body has a bottom plate for accommodating cylindrical batteries;

[0008] Multiple first and second adjustment plates are provided, with the first and second adjustment plates arranged parallel to each other within the pallet body; the inner sidewall of the pallet body and the upper surface of the bottom support plate are provided with guide structures for guiding the movement of the first and second adjustment plates;

[0009] A plurality of left locking plates, each of the left locking plates being fixedly mounted on the upper surface of a first adjusting plate and sliding together with the long axis of the first adjusting plate;

[0010] A plurality of right-hand plates, each of which is fixedly mounted on the upper surface of a second adjusting plate and slides together with the long axis of the second adjusting plate;

[0011] The left and right clamping plates are arranged opposite each other within the tray body to form a variable battery clamping gap. The distance between the left and right clamping plates is adjusted by sliding the first adjusting plate and / or the second adjusting plate.

[0012] Preferably, the guide structure includes a limiting groove disposed on the inner side wall of the pallet body and a slide rail disposed on the upper surface of the bottom support plate.

[0013] The base plate is provided with several battery mounting parts, and the base plate is hollow inside.

[0014] Preferably, the first adjusting plate and the second adjusting plate are flat plate structures, and the bottom surfaces of the first adjusting plate and the second adjusting plate that cooperate with the guide structure are provided with sliding contact parts.

[0015] Preferably, a plurality of the first adjustment plates and the second adjustment plates are arranged in groups at intervals within the tray body along the arrangement direction of the cylindrical batteries.

[0016] Preferably, the spacing between adjacent first and second adjustment plates is consistent with the center distance of the cylindrical battery.

[0017] Preferably, one side of the left card plate is provided with a diamond-shaped groove adapted to the outer wall of the cylindrical battery, and one side of the right card plate is provided with a symmetrical diamond-shaped groove opposite to the diamond-shaped groove of the left card plate.

[0018] Preferably, the left and right card plates move toward or away from each other.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] The guide structures on the inner wall of the tray body and the upper surface of the bottom plate provide smooth guidance for the movement of the first and second adjusting plates, ensuring a smooth and precise adjustment process. The left and right clamping plates are fixedly installed on the upper surface of the adjusting plates and stably positioned as the adjusting plates move, effectively ensuring the stability of the cylindrical batteries during clamping and preventing battery displacement or damage due to movement or vibration. By setting multiple first and second adjusting plates that can slide laterally within the tray body, and fixing the left and right clamping plates on these adjusting plates respectively, the battery clamping gap formed between the left and right clamping plates is variable. Operators can easily adjust the size of this gap by sliding the first and / or second adjusting plates, allowing a single-size tray to accommodate and load cylindrical batteries of various diameters. The sliding design of the adjusting plates is simple and convenient to operate; the distance between the left and right clamping plates can be quickly adjusted by sliding to accommodate changes in battery size. Compared to the cumbersome operation of replacing the entire tray required by traditional fixed-size trays, this reduces the time and labor costs associated with changing trays due to battery size adjustments, improving the overall efficiency of the production line. Because it is compatible with different types of cylindrical batteries, the tray structure of this invention improves its versatility. Manufacturers no longer need to redesign and purchase dedicated trays for every new battery model, thereby reducing the types and quantities of trays, simplifying inventory management, and enabling more flexible response to changes in market demand for different battery models. This avoids the need to frequently replace tray liners or remanufacture the entire tray mold due to changes in battery models. Attached Figure Description

Detailed Implementation

[0028] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0029] like Figures 1-4 As shown, the present invention provides a battery tray for holding cylindrical batteries 50, comprising:

[0030] The tray body 10 has a bottom support plate 11 for accommodating the cylindrical battery 50.

[0031] Multiple first adjustment plates 20 and second adjustment plates 21 are arranged parallel to each other inside the pallet body 10; the inner side wall of the pallet body 10 and the upper surface of the bottom support plate 11 are provided with guide structures 40 for guiding the movement of the first adjustment plates 20 and second adjustment plates 21.

[0032] Several left locking plates 30, each left locking plate 30 is fixedly installed on the upper surface of a first adjusting plate 20, and slides together with the long axis of the first adjusting plate 20;

[0033] Several right-side locking plates 31 are fixedly installed on the upper surface of a second adjusting plate 21 and slide together with the long axis of the second adjusting plate 21.

[0034] The left clamping plate 30 and the right clamping plate 31 are arranged opposite each other within the tray body 10 to form a variable battery clamping gap. The distance between the left clamping plate 30 and the right clamping plate 31 is adjusted by sliding the first adjusting plate 20 and / or the second adjusting plate 21.

[0035] The tray body 10 is a rectangular frame structure, providing a stable outer frame and foundation for loading the cylindrical battery 50. At the bottom of the tray body 10, there is a bottom support plate 11, which is used to support and accommodate the cylindrical battery 50.

[0036] The pallet body 10 contains multiple first adjustment plates 20 and second adjustment plates 21 that slide laterally in a linked manner. These adjustment plates are arranged parallel to each other within the pallet body 10 and typically slide along the upper surface of the bottom support plate 11. To ensure the stability of these first adjustment plates 20 and second adjustment plates 21 during sliding, guide structures 40 are provided at multiple locations on the inner sidewall of the pallet body 10 and on the upper surface of the bottom support plate 11 near the inner sidewall. Thus, the guide structures 40 can be located on the four walls of the pallet body 10, facilitating the installation of the adjustment plates and the locking plates. Specifically, straight grooves extending along the sliding direction of the adjustment plates can be provided on the inner sidewall of the pallet body 10; simultaneously, multiple corresponding straight grooves are also provided on the upper surface of the bottom support plate 11 near the inner sidewall. These guide structures 40 collectively limit the movement of the first adjustment plates 20 and second adjustment plates 21 along a predetermined lateral path and prevent them from deflecting or unnecessary shaking.

[0037] The left and right locking plates 30 are key components that directly contact and position the cylindrical battery 50. In this embodiment, each left locking plate 30 is fixedly mounted to the upper surface of its corresponding plurality of first adjustment plates 20 by screws, snap-fits, or other fixing methods. Therefore, when the first adjustment plate 20 slides within its guide structure 40 along its effective adjustment direction (i.e., the long axis direction, usually transverse), the left locking plate 30 fixed thereon also slides synchronously as a whole. Similarly, each right locking plate 31 is also fixedly mounted to the upper surface of its corresponding plurality of second adjustment plates 21 and slides together with the second adjustment plate 21 along its effective adjustment direction (long axis direction).

[0038] During actual battery loading, inside the tray body 10, each left clamping plate 30 and an opposing right clamping plate 31 together form one or more channels or gaps for clamping the cylindrical battery 50. The width of this clamping gap is variable during operation. The distance between the opposing left clamping plates 30 and right clamping plates 31 can be adjusted by sliding one or more first adjusting plates 20 (and their corresponding left clamping plates 30) and / or one or more second adjusting plates 21 (and their corresponding right clamping plates 31) laterally within the guide structure 40, either separately or simultaneously. When it is necessary to load cylindrical batteries 50 of different diameters, simply adjust the spacing to match the battery diameter. This will stably house and fix the batteries within the clamping space formed by the rhomboid grooves 301 of the left and right clamping plates 31. For example, when accommodating a cylindrical battery 50 with a larger diameter, the first adjusting plate 20 and the second adjusting plate 21 can be slid back-to-back to increase the spacing between the left and right clamping plates 30 and 31. Conversely, when accommodating a cylindrical battery 50 with a smaller diameter, they can be slid towards each other to decrease the spacing. This achieves stepless compatibility of the tray with different types of cylindrical batteries 50.

[0039] Implementation, for example Figure 2 and 3 As shown, preferably, the guide structure 40 includes a limiting groove 41 disposed on the inner side wall of the pallet body 10 and a slide rail 42 disposed on the upper surface of the bottom support plate 11.

[0040] The tray body 10 is preferably a rectangular frame structure with a certain strength and rigidity. At the bottom of the tray body 10, a bottom support plate 11 is provided. This bottom support plate 11 is not only used to support the cylindrical battery 50, but its structural design also takes into account lightweighting and specific functional requirements, specifically, its interior is a hollow structure.

[0041] To accommodate batteries of different sizes, the tray structure includes a guide structure 40. Preferably, the guide structure 40 comprises two parts: a limiting groove 41 extending along the sliding direction of the adjustment plate on the inner wall of the tray body 10; and a slide rail 42 parallel to the adjustment plate on the upper surface of the base plate 11. These limiting grooves 41 and slide rails 42 together provide stable and precise lateral sliding guidance or fixation for the subsequently introduced adjustment plate.

[0042] A plurality of battery mounting portions 111 are provided on the hollow base plate 11. According to this embodiment, and considering weight reduction, ventilation, or specific process requirements, the battery mounting portions 111 are characterized by an array of through-holes on the base plate 11 corresponding to each planned battery location. The diameter and arrangement of these through-holes are adapted to the cylindrical batteries 50 to be mounted. The bottom of the cylindrical battery 50 can partially or completely fall into these through-holes, obtaining support and initial radial positioning through the edges of the holes. This design makes the base plate 11 appear as a plate-like or grid-like structure with multiple circular openings.

[0043] When loading the battery, the cylindrical battery 50 is initially placed and positioned by engaging its bottom with the through circular hole (battery mounting part 111) on the base plate 11. Subsequently, by laterally sliding one or more first adjusting plates 20 (and their left clamping plates 30) and / or one or more second adjusting plates 21 (and their right clamping plates 31), the effective clamping distance between the opposing left and right clamping plates 30 and 31 can be adjusted so that the rhomboid groove 301 fits into the outer wall of the cylindrical battery 50 already positioned in the hole of the base plate 11 and securely clamps it. In this way, the tray structure can flexibly adapt to and firmly fix cylindrical batteries 50 of different sizes.

[0044] Implementation, for example Figure 2 and Figure 4As shown, multiple first adjustment plates 20 and multiple second adjustment plates 21 are arranged in parallel inside the tray body 10. Preferably, both the first adjustment plates 20 and the second adjustment plates 21 are flat plate structures, and their length direction is consistent with the long axis direction of the tray body 10, that is, extending along the direction of battery arrangement. In order to achieve smooth sliding adjustment, the bottom surfaces of the first adjustment plates 20 and the second adjustment plates 21 are provided with sliding contact portions. More specifically, the sliding contact portion is a groove structure that matches the slide rail 42 provided on the bottom of the tray body 10 (such as the upper surface of the bottom support plate 11). This ensures that when the adjustment plate slides laterally along the slide rail 42, it can maintain smooth and stable movement while effectively preventing unnecessary deviation or shaking. The inner sidewall of the tray body 10 may also be provided with corresponding limiting or guiding structures 40 to cooperate with the side of the adjustment plate, further enhancing its movement stability.

[0045] Several left locking plates 30 are fixedly installed on the upper surface of the corresponding multiple first adjustment plates 20 and slide laterally together with them. Several right locking plates 31 (similarly, can be assumed to be blue plates) are fixedly installed on the upper surface of the corresponding multiple second adjustment plates 21 and slide laterally together with them.

[0046] Preferably, multiple first adjustment plates 20 and second adjustment plates 21 are grouped and spaced apart within the tray body 10 along the arrangement direction of the cylindrical batteries 50. Specifically, for example, a group of first adjustment plates 20 and a group of second adjustment plates 21 can be arranged alternately. Each clamping unit formed by a first adjustment plate 20 (with a left clamping plate 30) and a second adjustment plate 21 (with a right clamping plate 31) corresponds to a clamping unit for one battery. When multiple such clamping units exist, the center distance between adjacent battery clamping units (i.e., the distance from the center of one battery to the center of the next battery) is consistent with the standard center distance required when the cylindrical batteries 50 are arranged side by side in the tray, thereby forming multiple continuous and equally spaced battery receiving channels.

[0047] Implementation, for example Figure 2 and Figure 3 As shown, regarding the clamping of the battery, one side of the left clamping plate 30 is provided with a diamond-shaped groove 301 that fits the outer wall of the cylindrical battery 50, and one side of the right clamping plate 31 is also provided with a diamond-shaped groove 301 that is opposite to and symmetrical in shape to the diamond-shaped groove 301 of the left clamping plate 30. These two opposing diamond-shaped grooves 301 together constitute the clamping interface for the cylindrical battery 50.

[0048] Preferably, the depth of the rhomboid groove 301 is designed to be 1 / 4 to 1 / 3 of the diameter of the cylindrical battery 50, and the opening directions of the two grooves are opposite to each other, forming an adjustable clamping gap. When the first adjusting plate 20 (carrying the left clamping plate 30) and the second adjusting plate 21 (carrying the right clamping plate 31) move closer to each other by sliding laterally, the two rhomboid grooves 301 can jointly cover and clamp the outer wall of the cylindrical battery 50, thereby restricting its degree of freedom of movement in the XY plane (usually a horizontal plane) of the tray.

[0049] To achieve optimal clamping and fit, when the cylindrical battery 50 is inserted, the outer wall of the battery will contact the four sides of the rhomboid groove, thus securing the battery. The size and angle of the rhomboid groove 301 should match the diameter and outer contour of the cylindrical battery 50 to ensure optimal fit and fixation.

[0050] The surface of the diamond-shaped groove 301 can be optionally treated with a smooth finish to reduce wear on the outer wall of the battery;

[0051] Or perhaps,

[0052] An anti-slip coating can be added to further enhance the fixation effect.

[0053] This ensures that the inner wall of the groove can fit against the cylindrical surface of the battery with the maximum area, thereby providing more uniform support and clamping force during clamping, avoiding stress concentration, and further improving positioning accuracy.

[0054] With the above structure, the operator can adjust the clamping gap width formed by the diamond-shaped grooves 301 of the left and right clamping plates 30 and 31 by sliding the first adjustment plate 20 and / or the second adjustment plate 21 laterally, so that it can adapt to and fix cylindrical batteries 50 of different diameters. When it is necessary to clamp a cylindrical battery 50 with a diameter of D, the closest distance between the diamond-shaped grooves 301 of the left and right clamping plates 31 can be adjusted to be approximately equal to D, or slightly larger than D, taking into account a small tolerance compensation value Δ (such as D+Δ), to ensure that the battery can be effectively fixed in the tray without generating excessive clamping stress, and remains tight and without shaking when arranged.

[0055] To achieve effective adjustment of the clamping gap, preferably, when adjusting the positions of the first adjusting plate 20 and the second adjusting plate 21, the left clamping plate 30 and the right clamping plate 31 fixed on them move towards or away from each other. Specifically, when it is necessary to clamp the battery or adapt to a battery with a smaller diameter, the first adjusting plate 20 carrying the left clamping plate 30 and the second adjusting plate 21 carrying the right clamping plate 31 are moved closer to each other, causing the left clamping plate 30 and the right clamping plate 31 to move towards each other, reducing the clamping gap. Conversely, when it is necessary to release the battery or adapt to a battery with a larger diameter, the first adjusting plate 20 and the second adjusting plate 21 are moved away from each other, causing the left clamping plate 30 and the right clamping plate 31 to move away from each other, increasing the clamping gap. The method of moving towards or away from each other helps to keep the battery approximately in the center of the clamping unit during the adjustment process and can quickly and symmetrically complete the gap adjustment. After adjusting to a suitable gap, the two rhomboid grooves 301 can jointly cover and clamp the outer wall of the cylindrical battery 50, thereby restricting its degree of freedom of movement in the XY plane of the tray.

[0056] In summary, the tray structure of this utility model achieves flexible compatibility with cylindrical batteries of different diameters through its adjustable design. Its core lies in the smooth sliding of the first and second adjustment plates within the guide structure, which drives the relative movement of the left and right clamping plates, creating a variable battery clamping gap. This design can adapt to various battery sizes without replacing the tray, improving versatility and production efficiency. The guide structure consists of limiting grooves on the inner wall and slide rails on the bottom plate, ensuring stable and precise adjustment; while the diamond-shaped grooves on the left and right clamping plates fit snugly against the outer wall of the battery, further enhancing clamping stability. The hollow bottom plate combined with the circular hole battery mounting section not only reduces overall weight but also facilitates rapid battery installation and initial positioning. This structural design balances ease of operation and economy, reducing production and operating costs, and flexibly responding to the diverse needs of the rapidly developing battery industry.

[0057] The working principle of the battery tray described in this utility model is as follows: the tray structure, through its internal adjustable mechanism, enables compatible loading and positioning of cylindrical batteries of different diameters. Its core working principle relies on left and right clamping plates fixedly mounted on laterally sliding adjustment plates. The tray body provides an overall frame, and its bottom support plate provides a basic bearing surface for the cylindrical batteries. Guide structures (such as slide rails or limiting grooves) provided on the inner wall of the tray body and / or the upper surface of the bottom support plate provide guidance and support for the lateral sliding of the first adjustment plate (carrying the left clamping plate) and the second adjustment plate (carrying the right clamping plate), ensuring their smooth movement. The left clamping plate is fixedly mounted on the corresponding first adjustment plate, and the right clamping plate is fixedly mounted on the corresponding second adjustment plate. The inner side of these clamping plates typically has diamond-shaped grooves adapted to the outer wall of the cylindrical battery. Operation allows one or more first adjustment plates and / or one or more second adjustment plates to slide laterally within the guide structure. When the first and second adjusting plates shift relative to each other, the fixed left and right clamping plates also move synchronously, changing the clamping gap between them. When loading batteries of different diameters, simply readjusting the positions of these adjusting plates changes the clamping gap without replacing the entire tray or its main components, thus achieving compatibility with various cylindrical battery models. Once the appropriate gap is achieved, the cylindrical battery is placed on the base plate and clamped from both sides by the diamond-shaped grooves of the opposing left and right clamping plates. This clamping method restricts the lateral movement of the battery within the tray's XY plane, achieving battery fixation and positioning.

[0058] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
