Description

Technical Field

[0001] This invention relates to the field of lithium battery assembly, and in particular to an assembly rack for lithium battery packs. Background Technology

[0002] Lithium-ion batteries are a type of battery that uses lithium metal or lithium alloys as the positive / negative electrode materials and a non-aqueous electrolyte solution. Due to the highly reactive chemical properties of lithium metal, its processing, storage, and use require very strict environmental control. With the development of science and technology, lithium-ion batteries have become the mainstream technology.

[0003] Currently, when using lithium batteries, due to different needs, some require multiple lithium batteries to be assembled into lithium battery packs for use. Currently, when assembling lithium battery packs, multiple lithium batteries need to be clamped and fixed to facilitate assembly by workers. However, if the clamping is too loose, it will affect the normal operation of workers. If it is too tight, it may cause certain deformation of the lithium batteries, affecting normal use and the quality of the finished lithium battery pack. To address this, we propose an assembly rack for lithium battery packs. Summary of the Invention

[0004] The main objective of this invention is to provide an assembly rack for lithium battery packs, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention proposes an assembly rack for lithium battery packs, comprising a base, a clamping assembly disposed on the base, and a driven stop assembly disposed inside and on the top of the base. The clamping assembly includes a rocker arm, a threaded rod, and a movable plate, and an abutment assembly disposed on the movable plate. The driven stop assembly includes:

[0006] A vertical rod, which passes through the top of the base and is slidably connected to the base;

[0007] A placement plate is fixed to the top of the vertical rod;

[0008] A skateboard, wherein a skateboard is fixed to the bottom of the vertical rod, and the skateboard is slidably mounted on the inner wall of the base;

[0009] Spring 1, the top of the skateboard is fixed with spring 1, and the end of spring 1 away from the skateboard is fixed to the inner wall of the base;

[0010] A one-way limiting component is provided at the bottom of the sliding plate;

[0011] A fixed column, wherein the threaded rod passes through the fixed column and is fixedly connected to the fixed column.

[0012] Optionally, the driven stop assembly includes a vertical rod, a placement plate, a sliding plate, a spring, a one-way limiting member, and a fixed column. The moving plate, the one-way limiting member, and the abutment assembly are all provided in two sets, and the two sets of moving plates, one-way limiting members, and abutment assemblies are symmetrically arranged with the center line of the base as the axis of symmetry.

[0013] Optionally, the one-way limiting member includes a fixed plate, which is fixed to the bottom of the slide plate. A limiting plate is hinged to the bottom of the fixed plate. A torsion spring is fixed to one side of the fixed plate, and a fixing block is fixed to the other side of the fixed plate. The end of the torsion spring away from the fixed plate is fixed to the limiting plate. Under the action of the fixing block, the limiting plate can only swing clockwise at the position hinged to the fixed plate.

[0014] Optionally, the rocker arm is rotatably mounted on the left side of the base, the left side of the base is penetrated by a threaded rod and rotatably connected to the threaded rod, the left side of the threaded rod is fixed to the right side of the rocker arm, the threaded rod penetrates the movable plate and is threadedly connected to the movable plate, and the movable plate penetrates the top of the base and is slidably connected to the base.

[0015] Optionally, the threaded rod is provided with two opposite threads, so that when the rocker arm is rotated, the two sets of moving plates can move towards or away from each other.

[0016] Optionally, the movable plate has a through hole for the plate to pass through, and the top of the base has a sliding groove for the movable plate to move left and right.

[0017] Optionally, the surface of the fixing post is provided with annular teeth, and the limiting plate can be inserted into the annular teeth on the surface of the fixing post to limit the threaded rod, so that the threaded rod can only rotate counterclockwise and not clockwise.

[0018] Optionally, the abutment assembly includes a support rod, one end of which is hinged to the inner wall of the movable plate and passes through the movable plate. The other end of the support rod is hinged to a rectangular block. A torsion spring is fixed to the inner wall of the movable plate, with the end of the torsion spring away from the movable plate fixed to the support rod. A torsion spring is fixed to the side of the rectangular block near the movable plate, with the end of the torsion spring away from the rectangular block fixed to the support rod. An abutment plate is inserted into the side of the rectangular block away from the support rod. The abutment plate is penetrated by a connecting rod and slidably connected to the connecting rod. A spring is fixed to the side of the abutment plate near the rectangular block, with the end of the spring away from the abutment plate fixed to the connecting rod. A limit block is fixed to the inner wall of the rectangular block. The abutment plate is a rubber plate. When the abutment plate contacts the lithium battery, it abuts against the lithium battery. As the movable plate moves towards the center of the base, the support rod can swing downward at the hinged position with the movable plate, allowing the abutment plate to move downward together with the lithium battery.

[0019] Optionally, the limiting block is provided with a through hole, which allows the connecting rod to be inserted to limit the position of the contact plate, ensuring the stability of the contact plate during use.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] (1) The lithium battery pack assembly frame, through the clamping component, driven stop component and abutment component, when the control moving plate moves to the side closer to the lithium battery, the abutment plate pushes the lithium battery to move downward, the placement plate pushes the slide plate downward through the vertical rod, the slide plate moves downward with the fixing plate and the limiting plate, the limiting plate inserts into the annular tooth on the surface of the fixing column, so that the threaded rod can only rotate counterclockwise and not clockwise, so as to avoid clamping the lithium battery too tightly, causing the lithium battery to deform, affecting the normal use of the lithium battery and the quality of the finished product.

[0022] (2) The lithium battery pack uses an assembly frame. When the contact plate and the lithium battery come into contact with each other, the connecting rod is pushed by the lithium battery and moves to the side closer to the rectangular block. The connecting rod is inserted into the through hole on the limiting block to limit the contact plate and ensure the stability of the contact plate during use.

[0023] (3) The lithium battery pack assembly frame, after processing, only needs to reverse the rocker arm. The rocker arm rotates counterclockwise with the threaded rod, so that the two sets of moving plates move in opposite directions. At this time, the threaded rod rotates with the fixed column. The annular teeth on the surface of the fixed column abut against the limiting plate, so that the limiting plate swings clockwise at the position of hinge with the fixed plate, which will not affect the normal counterclockwise rotation of the threaded rod.

[0038] Reference Figures 1 to 7 The present invention proposes an assembly frame for lithium battery packs, including a base 1, a clamping assembly 2 on the base 1, a driven stop assembly 3 inside and on the top of the base 1, the clamping assembly 2 including a rocker arm 21, a threaded rod 22 and a moving plate 23, and an abutment assembly 4 on the moving plate 23.

[0039] In this embodiment of the invention, the driven stop component 3 includes:

[0040] Vertical rod 31 passes through the top of base 1 and is slidably connected to base 1;

[0041] The placement plate 32 is fixed to the top of the vertical rod 31;

[0042] The bottom of the vertical rod 31 is fixed with a slide plate 33, which is slidably mounted on the inner wall of the base 1.

[0043] Spring 34 is fixed to the top of the slide plate 33, and the end of spring 34 away from the slide plate 33 is fixed to the inner wall of the base 1.

[0044] One-way limiting component 35, the bottom of the slide plate 33 is provided with one-way limiting component 35;

[0045] The fixed post 36 is connected to the threaded rod 22 through the fixed post 36.

[0046] Specifically, the driven stop assembly 3 includes a vertical rod 31, a placement plate 32, a sliding plate 33, a spring 34, a one-way limiting member 35, and a fixed column 36. The moving plate 23, the one-way limiting member 35, and the abutting assembly 4 are all provided in two sets, and the two sets of moving plates 23, one-way limiting members 35, and abutting assemblies 4 are symmetrically arranged with the center line of the base 1 as the axis of symmetry.

[0047] In one embodiment of the present invention, the one-way limiting member 35 includes a fixing plate 351, which is fixed to the bottom of the slide plate 33. A limiting plate 352 is hinged to the bottom of the fixing plate 351. A torsion spring 353 is fixed to one side of the fixing plate 351, and a fixing block 354 is fixed to the other side of the fixing plate 351. The end of the torsion spring 353 away from the fixing plate 351 is fixed to the limiting plate 352. Under the action of the fixing block 354, the limiting plate 352 can only swing clockwise at the position hinged to the fixing plate 351.

[0048] Please continue reading. Figure 1-7 The rocker arm 21 is rotatably mounted on the left side of the base 1. The left side of the base 1 is penetrated by the threaded rod 22 and rotatably connected to the threaded rod 22. The left side of the threaded rod 22 is fixed to the right side of the rocker arm 21. The threaded rod 22 penetrates the movable plate 23 and is threadedly connected to the movable plate 23. The movable plate 23 penetrates the top of the base 1 and is slidably connected to the base 1.

[0049] In addition, the threaded rod 22 is provided with two opposite threads, so that when the rocker arm 21 is rotated, the two sets of moving plates 23 can move towards or away from each other.

[0050] In order to affect the normal movement of the movable plate 23, the movable plate 23 is provided with a through hole, through which the plate 32 can pass. The top of the base 1 is provided with a sliding groove for the movable plate 23 to move left and right.

[0051] In an embodiment of the present invention, the surface of the fixing post 36 is provided with annular teeth, and the limiting plate 352 can be inserted into the annular teeth on the surface of the fixing post 36 to limit the threaded rod 22, so that the threaded rod 22 can only rotate counterclockwise and not clockwise.

[0052] In an embodiment of the present invention, the abutment component 4 includes a support rod 41, one end of which is hinged to the inner wall of the movable plate 23 and passes through the movable plate 23. The other end of the support rod 41 is hinged to a rectangular block 42. A torsion spring 43 is fixed to the inner wall of the movable plate 23, with the end of the torsion spring 43 away from the movable plate 23 fixed to the support rod 41. A torsion spring 44 is fixed to the side of the rectangular block 42 near the movable plate 23, with the end of the torsion spring 44 away from the rectangular block 42 fixed to the support rod 41. An abutment plate 45 is inserted into the side of the rectangular block 42 away from the support rod 41. 5 is slidably connected to the connecting rod 46. A second spring 47 is fixed on the side of the contact plate 45 near the rectangular block 42. The end of the second spring 47 away from the contact plate 45 is fixed to the connecting rod 46. A limit block 48 is fixed on the inner wall of the rectangular block 42. The contact plate 45 is a rubber plate. When the contact plate 45 contacts the lithium battery, the contact plate 45 abuts against the lithium battery. As the moving plate 23 moves towards the center of the base 1, the support rod 41 can swing downward at the hinge position with the moving plate 23, so that the contact plate 45 can move downward together with the lithium battery.

[0053] In an embodiment of the present invention, a through hole is provided on the limiting block 48, which allows the connecting rod 46 to be inserted to limit the contact plate 45 and ensure the stability of the contact plate 45 during use.

[0054] In this invention, when in use, the lithium battery to be assembled is placed on top of the placement plate 32, and the rocker arm 21 is turned. The rocker arm 21 rotates clockwise with the threaded rod 22, controlling the two sets of moving plates 23 to move towards each other. When the contact plate 45 contacts the lithium battery, the contact plate 45 abuts against the lithium battery. As the moving plate 23 moves towards the center of the base 1, the support rod 41 can swing downward at the hinge position with the moving plate 23, so that the contact plate 45 can move downward together with the lithium battery.

[0055] As the bottom of the placement plate 32 comes into contact with the top of the base 1, the placement plate 32 pushes the slide plate 33 downward via the vertical rod 31. The slide plate 33 moves downward along with the fixing plate 351 and the limiting plate 352. The limiting plate 352 is inserted into the annular teeth on the surface of the fixing post 36, thereby limiting the threaded rod 22 by the fixing post 36. This ensures that the threaded rod 22 can only rotate counterclockwise and not clockwise, preventing the lithium battery from being clamped too tightly, which could cause deformation of the lithium battery and affect its normal use and the quality of the finished product.

[0056] At the same time, the connecting rod 46 is pushed against the lithium battery and moves to the side closer to the rectangular block 42. The connecting rod 46 is inserted into the through hole on the limiting block 48 to limit the contact plate 45 and ensure the stability of the contact plate 45 during use.

[0057] After processing is completed, simply reverse the rocker arm 21. The rocker arm 21 rotates counterclockwise with the threaded rod 22, causing the two sets of moving plates 23 to move in opposite directions. At this time, the threaded rod 22 rotates with the fixed column 36. The annular teeth on the surface of the fixed column 36 abut against the limiting plate 352, causing the limiting plate 352 to swing clockwise at the position where it is hinged with the fixed plate 351. This will not affect the normal counterclockwise rotation of the threaded rod 22.

[0058] When the moving plate 23 resets with the abutment component 4, the lithium battery is no longer abutted. Under the action of spring 1 34, the sliding plate 33 resets upward with the placement plate 32 via the vertical rod 31. At the same time, under the action of spring 2 47, the connecting rod 46 resets and is no longer inserted into the through hole on the limiting block 48, thereby releasing the limitation on the abutment plate 45. The abutment plate 45 and the rectangular block 42 can be separated, and the abutment plate 45 can be replaced or cleaned.

[0059] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
