Description

Technical Field

[0001] This utility model relates to the field of lithium battery technology, and in particular to a lithium battery placement device. Background Technology

[0002] A lithium battery is a rechargeable battery that primarily functions by the movement of lithium ions between the positive and negative electrodes. During discharge, lithium ions are extracted from the negative electrode and inserted into the positive electrode via the electrolyte; during charging, lithium ions are extracted from the positive electrode and inserted into the negative electrode via the electrolyte. It boasts advantages such as high energy density, low self-discharge rate, and no memory effect, making it the primary power source for consumer electronics, electric vehicles, and energy storage systems. The core function of this placement device is to provide safe, stable, and reliable fixation and protection during the transportation, storage, and handling of lithium batteries.

[0003] Traditional lithium battery transport devices often suffer from unstable clamping due to their simple fixed structure, which can easily lead to battery displacement and collision, especially when the vehicle is bumpy. In addition, most clamping mechanisms lack pressure control, which can easily damage the battery cells. Furthermore, the locking of the box often relies on simple buckles, which poses a risk of loosening due to vibration.

[0004] Therefore, how to provide a lithium battery placement device is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] One objective of this invention is to provide a lithium battery placement device. This device includes a clamping assembly that can hold multiple lithium batteries, and a snap-fit ​​assembly that allows the hinge to be driven by an upward-pushing rod, causing the movable clamping plate to press against the through groove of the housing. This, combined with a threaded ring sleeve for rotational locking, forms a double-fixed structure, preventing damage to the lithium batteries caused by the top cover loosening during movement due to impacts. This addresses the problems mentioned in the background section.

[0006] A lithium battery placement device according to an embodiment of the present invention includes a placement box and a plug-in rod. A push-pull rod is slidably connected inside the plug-in rod. A threaded ring is formed on the top of the outer wall of the plug-in rod. A threaded ring sleeve is threadedly connected to the outer wall of the threaded ring. A plurality of rotating blocks are provided on the outer wall of the threaded ring sleeve. A connecting plate is fixedly connected to the top of the plug-in rod. A pull rod is fixedly connected to the top of the connecting plate. The connecting plate is slidably connected to the push-pull rod. A spring telescopic rod is fixedly connected to the bottom of the push-pull rod. The bottom of the spring telescopic rod is fixedly connected to the plug-in rod. Two hinges are fixedly connected to both sides of the bottom outer wall of the push-pull rod. A connecting rod is hinged inside the two hinges. A hinge is hinged to the end of the connecting rod away from the two hinges.

[0007] As a preferred embodiment of this utility model: a movable locking plate is fixedly connected to the end of the hinge member away from the push-pull rod, and the movable locking plate is movably connected to the plug rod.

[0008] As a further preferred embodiment of this utility model: a rotating motor is fixedly connected to the front right side of the placement box, and a drive sprocket is fixedly connected to the output end of the rotating motor.

[0009] As a further preferred embodiment of this utility model: a chain is meshed with the outer wall of the driving sprocket, a driven chain is meshed with the rear side of the inner wall of the chain, and a rotating rod is fixedly connected to the inner walls of the driving sprocket and the driven chain.

[0010] As a further preferred embodiment of this utility model: a plurality of threaded rods are fixedly connected to the outer wall of the rotating rod, and a movable block is threadedly connected to the outer wall of the threaded rod.

[0011] As a further preferred embodiment of this utility model: a movable clamping plate is fixedly connected to one end of the movable block near the middle of the placement box, and the left end of the rotating rod is rotatably connected to the placement box.

[0012] As a further preferred embodiment of this utility model: the top of the placement box is hinged to a top cover, and a number of springs are fixedly connected to the inner wall of the top cover, with a protective plate fixedly connected between the bottom ends of the springs.

[0013] As a further preferred embodiment of this utility model: a placement base plate is fixedly connected to the bottom of the inner wall of the placement box, and a plurality of fixing clamping plates are fixedly connected to the top of the placement base plate.

[0014] The beneficial effects of this utility model are:

[0015] The lithium battery placement device uses a rotating motor to drive a sprocket and chain mechanism, which simultaneously rotates multiple threaded rods. This allows the movable clamping plate to work in conjunction with the fixed clamping plate to quickly and evenly clamp the lithium battery. Combined with a pressure sensor, it prevents over-pressure damage to the battery. Simultaneously, an innovative linkage mechanism between the plug-in rod and the push-pull rod is designed. Pulling the push-pull rod drives the hinge to press the movable clamping plate against the through slot in the housing. This, along with the rotating locking of the threaded ring, forms a double fixation, preventing damage to the lithium battery caused by the top cover loosening during movement due to impacts.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0027] refer to Figure 1 , Figure 5 , Figure 6 , Figure 7 , Figure 8As shown, a lithium battery placement device includes a placement box 1 and a plug-in rod 9. A push-pull rod 7 is slidably connected inside the plug-in rod 9. A threaded ring 8 is formed on the top of the outer wall of the plug-in rod 9. A threaded ring sleeve 20 is threadedly connected to the outer wall of the threaded ring 8. Several rotating blocks 13 are provided on the outer wall of the threaded ring sleeve 20. A connecting plate 26 is fixedly connected to the top of the plug-in rod 9. A pull rod 5 is fixedly connected to the top of the connecting plate 26. The connecting plate 26 is slidably connected to the push-pull rod 7. A spring telescopic rod 22 is fixedly connected to the bottom of the push-pull rod 7. The bottom of the spring telescopic rod 22 is fixedly connected to the plug-in rod 9. Two hinges 25 are fixedly connected to both sides of the bottom outer wall of the push-pull rod 7. A connecting rod 24 is hinged inside the two hinges 25. A hinge 23 is hinged to the end of the connecting rod 24 away from the two hinges 25. A movable card plate 10 is fixedly connected to the end of the hinge 23 away from the push-pull rod 7. The movable card plate 10 is movably connected to the plug-in rod 9.

[0028] By pulling the push-pull rod 7 upwards, it is necessary to press down the pull rod 5 simultaneously to prevent the plug rod 9 from moving upwards when the push-pull rod is pulled upwards. Pulling the push-pull rod 7 will stretch the spring telescopic rod 22 at the bottom. Then, the hinges 25 on both sides of the bottom of the push-pull rod 7 will cause the connecting rod 24 to rotate upwards at the end near the push-pull rod 7. Thus, the connecting rod 24 will drive the movable plate 10 to rotate through the hinge 23, so that the top of the movable plate 10 is pressed against the top of the slot of the placement box 1. Then, the threaded ring sleeve 20 on the outer wall of the threaded ring 8 will rotate downwards until it is pressed against the top of the top cover 4, which can ensure that the buckle assembly is in a tight state. If it is necessary to disengage, the operation can be reversed. A limit block is set on the outer wall of the push-pull rod 7 to prevent the force of pulling the push-pull rod 7 upwards from being too great and causing the movable plate 10 to press against the top of the inner wall of the slot of the placement box 1.

[0029] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, a rotating motor 6 is fixedly connected to the front right side of the placement box 1. A drive sprocket 21 is fixedly connected to the output end of the rotating motor 6. A chain 2 is meshed with the outer wall of the drive sprocket 21. A driven chain 3 is meshed with the rear side of the inner wall of the chain 2. A rotating rod 17 is fixedly connected to the inner wall of the drive sprocket 21 and the driven chain 3. Several threaded rods 16 are fixedly connected to the outer wall of the rotating rod 17. A movable block 15 is threadedly connected to the outer wall of the threaded rod 16. A movable clamping plate 18 is fixedly connected to one end of the movable block 15 near the middle of the placement box 1. The left end of the rotating rod 17 is rotatably connected to the placement box 1. A top cover 4 is hinged to the top of the placement box 1. Several springs 11 are fixedly connected to the inner wall of the top cover 4. A protective plate 12 is fixedly connected between the bottom ends of the springs 11. A placement base plate 14 is fixedly connected to the bottom of the inner wall of the placement box 1. Several fixed clamping plates 19 are fixedly connected to the top of the placement base plate 14.

[0030] The rotating motor 6 is started, which drives the rotating rod 17 at the output end to rotate. The rotation of the rotating rod 17 drives the driving sprocket 21 on the outer wall to rotate. The rotation of the driving sprocket 21 drives the chain 2 on the outer wall to mesh and rotate. The meshing and rotation of the chain 2 drives the driven chain 3 on the rear side of the inner wall to rotate. The rotation of the driven chain 3 drives the rotating rod 17 inside to rotate. The rotation of the rotating rod 17 drives the threaded rod 16 on the outer wall to rotate. The rotation of the threaded rod 16 drives the movable block 15 on the outer wall to move. The movement of the movable block 15 drives the movable clamping plate 18 to move. The movement of the movable clamping plate 18 can cooperate with the fixed clamping plate 19 to clamp the lithium battery. A pressure sensor is provided on the inner wall of the fixed clamping plate 19 on the side where the lithium battery is clamped to prevent the rotating motor 6 from driving the movable clamping plate 18 to clamp the lithium battery with excessive force, which could damage it.

[0031] Working principle:

[0032] First, open the top cover 4 of the placement box 1. Then, place the lithium batteries on the side closest to the movable clamping plate 18 and the fixed clamping plate 19. Next, start the rotating motor 6 to drive the rotating rod 17 at the output end to rotate. The rotation of the rotating rod 17 drives the driving sprocket 21 on the outer wall to rotate. The rotation of the driving sprocket 21 drives the chain 2 on the outer wall to mesh and rotate. The meshing and rotation of the chain 2 drives the driven chain 3 on the rear side of the inner wall to rotate. The rotation of the driven chain 3 drives the internal rotating rod 17 to rotate. The rotation of the rotating rod 17 drives the threaded rod 16 on the outer wall to rotate. The rotation of the threaded rod 16 drives the movable block 15 on the outer wall to move. The movement of the movable block 15 drives the movable clamping plate 18 to move. The movement of 8 can be used to clamp the lithium battery with the fixed clamping plate 19. Then, close the top cover 4 and pull the push-pull rod 7 upward. While pulling the push-pull rod 7 upward, the pull rod 5 needs to be pressed down. Pulling the push-pull rod 7 can cause the bottom spring telescopic rod 22 to stretch. Then, the hinges 25 on both sides of the bottom of the push-pull rod 7 can drive the connecting rod 24 to rotate upward near the end of the push-pull rod 7. Thus, the connecting rod 24 can drive the movable card plate 10 to rotate through the hinge 23, so that the top of the movable card plate 10 is pressed against the top of the slot of the placement box 1. Then, rotate the threaded ring sleeve 20 on the outer wall of the threaded ring 8, so that the threaded ring sleeve 20 rotates downward until it is pressed against the top of the top cover 4, which can ensure the fastening assembly is in a tight state. If it is necessary to disconnect, the operation can be reversed.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
