Abstract

This utility model relates to the field of plastic battery cell holder technology, and more particularly to a quick-insertion plastic inner core holder, comprising: a plastic base, a shock-absorbing clamping assembly disposed within the plastic base, a splicing assembly disposed on the outer side of the plastic base, and an arc-shaped placement platform disposed at the bottom of the inner side of the plastic base, with an anti-slip pad disposed on the arc-shaped placement platform. This utility model, by incorporating the shock-absorbing clamping assembly, can flexibly adapt to lithium battery cells of different diameters, ensuring that the lithium battery cell receives uniform clamping force after insertion, preventing loosening. Simultaneously, the movement of the piston rod and piston one within the oil reservoir, and the damping force generated during the flow of hydraulic oil, effectively slows down the rebound speed of the buffer spring, not only enhancing clamping stability but also effectively absorbing vibration. The shock-absorbing clamping assembly not only simplifies the installation steps of the lithium battery cell and the plastic base, enabling quick insertion and removal, but also ensures the stability of the lithium battery cell during operation, extending its service life.

Description

Technical Field

[0001] This utility model relates to the field of plastic battery holder technology, and in particular to a plastic inner core holder that can be quickly inserted and removed. Background Technology

[0002] A lithium-ion battery cell is the core of a lithium-ion battery, primarily responsible for storing and converting energy. A lithium-ion battery cell consists of components such as positive electrode material, negative electrode material, electrolyte, separator, and casing, and features high voltage platform, high energy density, long lifespan, and environmental friendliness.

[0003] However, the existing methods of fixing multiple lithium cells in the core of lithium batteries are relatively simple and they are closely adjacent to each other, which leads to the instability of the core structure of lithium batteries and increases the risk of safety accidents. Although some lithium batteries use core holders to arrange the lithium cells in a regular manner, these core holders are often complex in structure, which seriously reduces the effective utilization of space and makes it impossible to quickly insert and remove lithium cells when needed, thus reducing the efficiency of production and later maintenance. Utility Model Content

[0004] The purpose of this invention is to provide a quick-pluggable plastic core holder to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: it includes a plastic base, a shock-absorbing clamping assembly is provided inside the plastic base, a splicing assembly is provided on the outside of the plastic base, an arc-shaped placement platform is provided at the bottom inside the plastic base, and an anti-slip pad is provided on the arc-shaped placement platform.

[0006] As a preferred embodiment of the present invention, the shock-absorbing clamping assembly includes a pair of arc-shaped clamping seats disposed within a plastic base. Several mounting plates are disposed on the inner walls of both sides of the plastic base, and an oil reservoir is disposed on one side of each mounting plate.

[0007] As a preferred embodiment of this utility model, each of the two arc-shaped clamping seats is provided with a mounting plate two on one side corresponding to the position of mounting plate one. Each mounting plate two is provided with a piston rod on the side away from the arc-shaped clamping seat. Each piston rod is provided with a piston one. The piston one is slidably disposed in the oil storage cylinder. A buffer spring is provided between mounting plate one and mounting plate two. Each of the two arc-shaped clamping seats is provided with an anti-slip pad two on one side.

[0008] As a preferred embodiment of the present invention, the splicing assembly includes a pair of mounting plates three disposed on the upper and lower sides of the plastic base. Each of the two mounting plates three is provided with a connector on one side. An arc-shaped fastener one is movably disposed on one side of the connector, and an arc-shaped fastener two is movably disposed on the side of the connector away from the arc-shaped fastener one.

[0009] As a preferred embodiment of this utility model, each of the arc-shaped fastener 1 and arc-shaped fastener 2 is provided with a mounting plate 4 on one side, and each of the two mounting plates 4 is provided with a spring 1. The ends of the two springs 1 away from the mounting plate 4 are connected to the mounting plate 3. The plastic base is provided with a card holder corresponding to the arc-shaped fastener 1 and arc-shaped fastener 2 on the side away from the mounting plate 3.

[0010] As a preferred embodiment of this utility model, the top of the plastic base is provided with a plug-in block, and the bottom of the plastic base is provided with a plug-in groove corresponding to the plug-in block.

[0011] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0012] This invention, through the design of a shock-absorbing clamping assembly, combines an arc-shaped clamping seat with a buffer spring to flexibly adapt to lithium battery cells of different diameters. This ensures that the lithium battery cell receives uniform clamping force after insertion, preventing loosening. Simultaneously, the movement of the piston rod and piston one within the oil reservoir, along with the damping force generated by the hydraulic oil flow, effectively slows down the rebound speed of the buffer spring, enhancing clamping stability and effectively absorbing vibrations. Furthermore, the anti-slip pad two increases the friction between the arc-shaped clamping seat and the lithium battery cell, effectively preventing the lithium battery cell from sliding or falling off during use. The shock-absorbing clamping assembly not only simplifies the installation steps of the lithium battery cell and the plastic base, enabling quick insertion and removal, but also ensures the stability of the lithium battery cell during operation, extending its service life.

[0013] This invention, through the design of splicing components, enables convenient horizontal and vertical splicing of the plastic inner core base, greatly improving space utilization and operational stability. The use of arc-shaped fasteners one and two in conjunction with the mounting bracket facilitates rapid horizontal connection between the plastic bases. When the plastic base is pushed in, arc-shaped fasteners one and two open under pressure, simultaneously compressing spring one. After the mounting bracket is fully engaged, spring one releases its elastic potential energy, pushing arc-shaped fasteners one and two back to their original positions and firmly engaging with the mounting bracket. Furthermore, the combination of the insertion block and insertion slot provides a convenient method for vertical splicing; simply align the insertion block with the insertion slot and push it in. The splicing components not only allow the lithium battery core to be composed of multiple lithium battery cells arranged in a regular pattern, improving the overall structural stability, but also facilitate subsequent maintenance, reducing operational difficulty and time costs.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0021] like Figures 1-5 As shown, this utility model proposes a quick-insertion plastic core holder, which includes a plastic base 1. The plastic base 1 is used to place the lithium battery cell and ensure the stability and safety of the lithium battery cell after insertion. A shock-absorbing clamping component 2 is provided inside the plastic base 1, and a splicing component 3 is provided on the outside of the plastic base 1. An arc-shaped placement platform 4 is provided at the bottom inside the plastic base 1. An anti-slip pad 5 is provided on the arc-shaped placement platform 4. The arc-shaped placement platform 4 provides a placement platform for the lithium battery cell, which helps to correctly position and stably place the lithium battery cell, while the anti-slip pad 5 increases the friction between the lithium battery cell and the arc-shaped placement platform 4.

[0022] The shock-absorbing clamping assembly 2 includes a pair of arc-shaped clamping seats 23 disposed in the plastic base 1. The arc-shaped clamping seats 23 are used to clamp and fix the lithium battery cell. The arc-shaped design helps to adapt to the shape of the lithium battery cell and provide uniform clamping force. Several mounting plates 21 are provided on the inner walls of both sides of the plastic base 1. Each mounting plate 21 has an oil reservoir 22 on one side, which stores hydraulic oil.

[0023] Two mounting plates 24 are provided on one side of each of the two arc-shaped clamping seats 23, corresponding to the position of mounting plate 21. A piston rod 25 is provided on the side of each mounting plate 24 away from the arc-shaped clamping seat 23. A piston 26 is mounted on each piston rod 25. The piston 26 is slidably disposed within the oil reservoir 22. The oil reservoir 22, piston rod 25, and piston 26 form a hydraulic damping system. The piston 26, slidably disposed within the oil reservoir 22, allows hydraulic oil to flow between the two chambers within the oil reservoir 22 through a small hole. This generates damping force, which helps to slow down the rebound speed of the buffer spring 27. A buffer spring 27 is provided between the mounting plate 1 21 and the mounting plate 24. The buffer spring 27 can not only contract to adapt to the diameter of the lithium battery cell when it is inserted, but also work with the hydraulic damping system to effectively absorb vibration. Anti-slip pads 28 are provided on one side of each of the two arc-shaped clamping seats 23. The anti-slip pads 28 can increase the friction between the arc-shaped clamping seats 23 and the lithium battery cell, preventing the lithium battery cell from sliding or falling off during use.

[0024] The splicing component 3 includes a pair of mounting plates 31 disposed on the upper and lower sides of the plastic base 1. The mounting plates 31 provide a mounting base for the connectors 32. Each mounting plate 31 has a connector 32 on one side. The connectors 32 provide a mounting base for the arc-shaped fasteners 33 and 34, and allow the arc-shaped fasteners 33 and 34 to rotate around the connectors 32 at a certain angle. The arc-shaped fastener 33 is movably disposed on one side of the connectors 32. An arc-shaped fastener 34 is movably provided on the side of the connector 32 away from the arc-shaped fastener 33. The arc-shaped fastener 33 and the arc-shaped fastener 34 are used to engage with the card holder 37 of the adjacent plastic seat 1. When the plastic seat 1 is pushed in, the arc-shaped fastener 33 and the arc-shaped fastener 34 are opened to both sides under pressure. After the card holder 37 is fully engaged, the spring 36 releases its elastic potential energy, pushing the arc-shaped fastener 33 and the arc-shaped fastener 34 to be firmly engaged with the card holder 37.

[0025] Each of the arc-shaped fasteners 33 and 34 has a mounting plate 35 on one side. Each of the two mounting plates 35 has a spring 36. The ends of the two springs 36 away from the mounting plate 35 are connected to the mounting plate 31. When the arc-shaped fasteners 33 and 34 are opened under pressure, the springs 36 are compressed. After the external force is removed, the springs 36 release their elastic potential energy, pushing the arc-shaped fasteners 33 and 34 to reset and lock firmly. Each of the plastic bases 1 has a corresponding retainer 37 on the side away from the mounting plate 31. The arc-shaped fasteners 33 and 34 cooperate with the retainer 37 to achieve the lateral splicing between the plastic bases 1.

[0026] The top of the plastic base 1 is provided with a plug-in block 38, and the bottom of the plastic base 1 is provided with a plug-in groove 39 corresponding to the plug-in block 38. The combination of the plug-in block 38 and the plug-in groove 39 can realize the vertical splicing between the plastic bases 1.

[0027] During use, the operator first aligns the lithium battery cell with the arc-shaped placement platform 4 inside the plastic base 1 and pushes it in. During the pushing process, the arc-shaped clamping seats 23 on both sides of the plastic base 1 are subjected to pressure, and the buffer spring 27 contracts to increase the distance between the two arc-shaped clamping seats 23, thereby accommodating the diameter of the lithium battery cell. At the same time, the arc-shaped clamping seats 23 push the piston rod 25 and piston 26 to move inside the oil reservoir 22. Piston 26 divides the space inside the oil reservoir 22 into two chambers, and the hydraulic oil in the oil reservoir 22 will pass through piston 26. Different small holes repeatedly flow from one cavity to another. During the flow of hydraulic oil, the friction between the hole wall and the hydraulic oil and the internal friction between hydraulic oil molecules will hinder the flow of hydraulic oil, thereby generating damping force, slowing down the rebound speed of the buffer spring 27, ensuring the stability of the arc-shaped clamping seat 23, and realizing stable clamping of the lithium battery cell. At the same time, the combination of the buffer spring 27 and the hydraulic damping system can also effectively absorb vibration, ensure the stability of the lithium battery cell during operation, simplify the installation steps of the lithium battery cell and the plastic seat 1, and realize quick insertion and removal.

[0028] The core of a lithium battery is usually composed of multiple lithium battery cells. The operator can align the arc-shaped fasteners 33 and 34 on one side of the first plastic base 1 with the retaining plate 37 on the other side of the second plastic base 1 and push them in. When the arc-shaped fasteners 33 and 34 come into contact with the protruding part on the retaining plate 37, they will be subjected to pressure and open to both sides. When they open, the mounting plate 35 will compress the spring 36. After the retaining plate 37 is fully inserted, the external force will disappear, and the spring 36 will release its elastic potential energy, pushing the arc-shaped fasteners 33 and 34 to firmly engage with the retaining plate 37. The remaining plastic bases 1 can be horizontally spliced ​​in sequence according to the above steps. When vertical splicing is required after horizontal splicing, simply align the insertion slot 39 at the bottom of the first row of plastic bases 1 with the insertion block 38 on the second row of plastic bases 1 and push it in. This allows for independent installation and regular arrangement of lithium battery cells, improving space utilization and stability during operation.
