Description

Technical Field

[0001] This utility model relates to the field of battery cell support technology, specifically a lithium battery cell support. Background Technology

[0002] Lithium-ion batteries, as a core component of modern new energy technologies, are widely used in electric vehicles, energy storage systems, and portable electronic devices. However, battery cells are susceptible to mechanical vibration and thermal runaway during operation; therefore, the design of the cell support structure is crucial to battery safety, lifespan, and performance. Current cell support structures still face the following significant challenges:

[0003] The lack of adaptability to different sizes (especially lengths) of battery cells is a pain point. Existing mounting brackets mostly adopt a fixed height design, requiring the customization of different specifications of brackets to adapt to changes in battery cell length, which increases costs. For example, although some brackets form a storage space by combining upper and lower brackets, they lack a height adjustment structure, making it impossible to flexibly adapt to multiple specifications of battery cells and limiting versatility. To address this, we provide a lithium battery cell bracket to solve the aforementioned problems. Summary of the Invention

[0004] The purpose of this invention is to provide a lithium battery cell support to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A lithium battery cell support includes a support, a lower cover plate on the support, a crossbeam above the lower cover plate, an upper cover plate on the crossbeam, a limiting component for the crossbeam to move up and down between the support and the crossbeam, and a lifting mechanism for manually adjusting the height of the upper cover plate on the support.

[0007] The lifting mechanism includes an L-shaped frame fixed on both sides of the support. The L-shaped frame has a spring groove. A slider and a spring are movably engaged in the spring groove from top to bottom. A bolt fixing plate is provided on the slider. The bolt fixing plate is locked to the upper cover plate by bolts. An adjustment mechanism is provided on the L-shaped frame to drive the slider to slide up and down in the spring groove.

[0008] As described above, a lithium battery cell support has battery slots on the lower cover plate and the upper cover plate for embedding and snapping the two ends of the cell. The battery slots are arranged in an array on the lower cover plate and the upper cover plate.

[0009] As described above, a lithium battery cell support includes a limiting screw fixed on the support and a mounting hole on the crossbeam. The limiting screw is movably inserted into the mounting hole and locked to the top of the crossbeam by a locking bolt sleeved on the limiting screw.

[0010] As described above, a lithium battery cell support includes an adjustment mechanism comprising a first rotating rod and a second rotating rod rotatably mounted on an L-shaped frame. The first and second rotating rods are vertically distributed and are driven by a gear mechanism. When the first rotating rod rotates, it drives the second rotating rod to rotate synchronously. One end of the second rotating rod is provided with an external threaded rod, and a threaded sleeve is threadedly fitted onto the external threaded rod. The L-shaped frame has a through groove, and the threaded sleeve is fixedly connected to a slider via a connecting rod that is movably engaged in the through groove.

[0011] A lithium battery cell support as described above: the gear mechanism includes a driven bevel gear fixed on a second rotating rod and a driving bevel gear fixed on a first rotating rod, wherein the driven bevel gear meshes with the driving bevel gear.

[0012] As described above, a lithium battery cell support has a handwheel fixedly mounted at the end of the first rotating rod.

[0013] A lithium battery cell support as described above: a sealing ring is embedded inside the battery slot to seal the gap between the end of the cell and the battery slot after the end of the cell is snapped into the battery slot.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: a lower cover plate is fixed on the bracket, and a non-fixed upper cover plate is set above the lower cover plate. The bracket is equipped with a lifting mechanism for manually adjusting the height of the upper cover plate. The lifting mechanism includes an L-shaped frame, a first rotating rod, etc. In use, the first rotating rod is manually rotated to drive the external threaded rod at one end of the second rotating rod to rotate. The threaded sleeve and the external threaded rod are threaded together to drive the threaded sleeve to move up and down, thereby driving the upper cover plate fixed on one side of the threaded sleeve to move up and down, thus adjusting the height of the upper cover plate.

[0015] Therefore, by setting a non-fixed upper cover plate and cooperating with a lifting mechanism to adjust the height of the upper cover plate to change the accommodating space formed by the combination of the lower cover plate and the upper cover plate, this utility model can flexibly adapt to multiple specifications of battery cells, no longer adopting a fixed height design, and eliminating the need to customize different specifications of brackets to adapt to changes in battery cell length, thus significantly reducing costs.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Please see Figures 1 to 7 As an embodiment of this utility model, a lithium battery cell support includes a support 1, a lower cover plate 2 is provided on the support 1, a crossbeam 3 is provided above the lower cover plate 2, an upper cover plate 4 is provided on the crossbeam 3, a limiting component for the crossbeam 3 to move up and down is provided between the support 1 and the crossbeam 3, and a lifting mechanism for manually adjusting the height of the upper cover plate 4 is provided on the support 1.

[0026] The lifting mechanism includes an L-shaped frame 10 fixed on both sides of the bracket 1. The L-shaped frame 10 has a spring groove 18. A slider 16 and a spring 19 are movably engaged in the spring groove 18 from top to bottom. A bolt fixing plate 17 is provided on the slider 16. The bolt fixing plate 17 is locked to the upper cover plate 4 by bolts. An adjustment mechanism is provided on the L-shaped frame 10 to drive the slider 16 to slide up and down in the spring groove 18.

[0027] The lower cover plate 2 and the upper cover plate 4 are respectively provided with battery slots 8 for embedding and snapping the two ends of the battery cell 9. The battery slots 8 are respectively arranged in an array on the lower cover plate 2 and the upper cover plate 4.

[0028] In this embodiment, a lower cover plate 2 is fixed on a bracket 1, and a non-fixed upper cover plate 4 is set above the lower cover plate 2. The bracket 1 is equipped with a lifting mechanism for manually adjusting the height of the upper cover plate 4. The lifting mechanism includes an L-shaped frame 10, a spring groove 18, etc. In use, the bottoms of multiple battery cells 9 are first respectively snapped into the battery slots 8 opened on the lower cover plate 2. The slider 16 is driven to slide up and down in the spring groove 18 through the adjustment mechanism, thereby driving the upper cover plate 4 fixed on one side of the slider 16 to move up and down, adjusting the height of the upper cover plate 4 so that the top of the battery cell 9 is snapped into the battery slots 8 opened on the upper cover plate 4. The battery cell 9 is supported and placed using the accommodating space between the upper cover plate 4 and the lower cover plate 2.

[0029] By setting a non-fixed upper cover plate 4 and cooperating with a lifting mechanism to adjust the height of the upper cover plate 4, the accommodating space formed by the combination of the lower cover plate 2 and the upper cover plate 4 can be changed, thereby flexibly adapting to multiple specifications of battery cells 9. The fixed height design is no longer required, and different specifications of brackets are not needed to adapt to the changes in the length of the battery cells 9, significantly reducing costs.

[0030] As a further embodiment of this utility model, the limiting component includes a limiting screw 5 fixed on the bracket 1 and a mounting hole 6 opened on the crossbeam 3. The limiting screw 5 is movably inserted into the mounting hole 6 and the top of the crossbeam 3 is locked by a locking bolt 7 sleeved on the limiting screw 5.

[0031] In this embodiment, the limiting screw 5 is inserted into the mounting hole 6. When the upper cover plate 4 moves up and down, the crossbeam 3 moves up and down synchronously. Thus, the limiting screw 5 limits the up and down movement of the crossbeam 3, thereby limiting the up and down movement of the upper cover plate 4 to ensure that its position does not shift during the up and down movement. After the height adjustment of the upper cover plate 4 is completed, its bottom is supported by the spring 19. Then, the locking bolt 7 is threadedly connected to the limiting screw 5 to lock the top of the crossbeam 3, thereby fixing the position of the upper cover plate 4 after the height adjustment.

[0032] As a further embodiment of this utility model, the adjustment mechanism includes a first rotating rod 11 and a second rotating rod 12 rotatably mounted on an L-shaped frame 10. The first rotating rod 11 and the second rotating rod 12 are vertically distributed and are driven by a gear mechanism. When the first rotating rod 11 rotates, it will drive the second rotating rod 12 to rotate synchronously. One end of the second rotating rod 12 is provided with an external threaded rod 13, and a threaded sleeve 15 is threadedly fitted on the external threaded rod 13. A through groove 14 is provided on the L-shaped frame 10, and the threaded sleeve 15 is fixedly connected to the slider 16 through a connecting rod that is movably engaged in the through groove 14.

[0033] In this embodiment, the first rotating rod 11 is rotated, and the first rotating rod 11 and the second rotating rod 12 are driven by a gear mechanism. When the first rotating rod 11 rotates, it will drive the second rotating rod 12 to rotate synchronously. One end of the second rotating rod 12 is provided with an external thread rod 13. When the second rotating rod 12 rotates, it will drive the external thread rod 13 to rotate. The threaded sleeve 15 is driven to move up and down by the threaded engagement with the external thread rod 13, thereby driving the upper cover plate 4 fixed by the bolt fixing plate 17 at the end of the slider 16 to move up and down.

[0034] As a further embodiment of this utility model, the gear mechanism includes a driven bevel gear 20 fixed on the second rotating rod 12 and a driving bevel gear 21 fixed on the first rotating rod 11, wherein the driven bevel gear 20 meshes with the driving bevel gear 21.

[0035] In this embodiment, rotating the first rotating rod 11 will drive the driving bevel gear 21 to rotate. The driven bevel gear 20 meshes with the driving bevel gear 21, which will drive the driven bevel gear 20 to rotate, thereby driving the second rotating rod 12 to rotate.

[0036] As a further embodiment of this utility model, a handwheel 22 is fixedly installed at the end of the first rotating rod 11.

[0037] In this embodiment, a handwheel 22 is provided to facilitate manual rotation of the first lever 11 by the user, thereby increasing the convenience of adjusting the rotation of the first lever 11.

[0038] As a further embodiment of this utility model, a sealing ring is embedded inside the battery slot 8 to seal the gap between the end of the battery cell 9 and the battery slot 8 after the end of the battery cell 9 is snapped into the battery slot 8.

[0039] In this embodiment, the sealing ring is used to form a seal at the gap between the battery cell 9 and the upper cover plate 4 and the limiting screw 5, ensuring that the end of the battery cell 9 has good sealing performance and reducing interference from external dust and moisture. In addition, the sealing ring can also play a pressure relief buffering role when the end of the battery cell 9 is pressed, ensuring the normal operation of the internal components of the battery cell 9, thereby ensuring the life and safety of the battery cell 9.

[0040] This utility model uses a bracket 1 to fix a lower cover plate 2, and a non-fixed upper cover plate 4 above the lower cover plate 2. The bracket 1 is equipped with a lifting mechanism for manually adjusting the height of the upper cover plate 4. The lifting mechanism includes an L-shaped frame 10, a spring groove 18, etc. In use, the bottoms of multiple battery cells 9 are first respectively snapped into the battery slots 8 opened on the lower cover plate 2. The adjustment mechanism drives the slider 16 to slide up and down in the spring groove 18, thereby driving the upper cover plate 4 fixed on one side of the slider 16 to move up and down, adjusting the height of the upper cover plate 4 so that the top of the battery cell 9 is snapped into the battery slots 8 opened on the upper cover plate 4. The space between the upper cover plate 4 and the lower cover plate 2 is used to support and place multiple battery cells 9.

[0041] This utility model uses a non-fixed upper cover plate 4 and a lifting mechanism to adjust the height of the upper cover plate 4 to change the accommodating space formed by the combination of the lower cover plate 2 and the upper cover plate 4, thereby flexibly adapting to the use of various specifications of battery cells 9.

[0042] The above embodiments are exemplary and not restrictive. Therefore, without departing from the spirit or basic characteristics of this utility model, any technical solutions that can be implemented in other specific forms are included in this utility model.
