Description

Technical Field

[0001] The utility model belongs to the technical field of lithium batteries, in particular to a high-stability lithium battery box. Background Art

[0002] With the development of science and technology, the number of electronic intelligent devices is increasing. In order to improve the convenience and reliability of electronic intelligent devices, most mobile electronic devices are currently powered by batteries. Among them, lithium batteries are the most widely used and are widely used in various fields such as transportation, medical treatment, military, and energy storage. Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. After the lithium battery pack is assembled and installed, it is usually necessary to use a battery box to protect the lithium battery pack to ensure that the lithium battery pack can be used stably for a long time.

[0003] The structural stability of the lithium battery box is crucial to ensure the safety of the battery during transportation and use. At present, there are some lithium battery boxes on the market with design defects, which may cause safety hazards during transportation or use, and increase the difficulty of battery maintenance and replacement. First, the structural instability of the lithium battery box is usually due to its design deficiencies. During transportation, the box may be subjected to impact, vibration and other forms of external forces. If the box structure is not strong enough, this may cause the battery to be out of its fixed position or shifted, thereby increasing the risk of battery damage and may trigger serious safety accidents such as short circuits or even fires. Secondly, the current lithium battery replacement and maintenance process is insufficient in terms of convenience. If the battery box adopts a fixed structure and the actual needs of rapid replacement and maintenance are not fully considered, then when replacing or maintaining the battery, the staff may need to spend a lot of time and energy on disassembly and reassembly operations. This not only increases the workload, but may also cause additional damage to the battery during replacement and maintenance. Utility Model Content

[0004] In order to solve the problem that lithium batteries are easily detached and damaged, and are inconvenient to replace and repair in the battery box in the prior art, the utility model provides a high-stability lithium battery box, which can clamp and fix the lithium batteries by arranging anti-detachment components, buffer plates and buffer springs in the inner box body. At the same time, the cooperation of the anti-detachment components, buffer plates and buffer springs can not only provide buffering for the lithium batteries, but also prevent the lithium batteries from detaching from the inner box body, thereby effectively improving the risk resistance of the lithium batteries.

[0005] To achieve the above purpose, the specific technical solution is as follows:

[0006] A high-stability lithium battery box comprises an outer box body and a box cover, and also comprises: an inner box body, which is arranged inside the outer box body; and an anti-slip assembly, which comprises two groups of anti-slip assemblies symmetrically mounted on the two side walls of the upper part of the inner box body; and a buffer plate, which comprises two groups of buffer plates, both groups of buffer plates being mounted on the bottom of the inner box body via buffer springs arranged on their side walls; the buffer plate and the anti-slip assembly are located on the same side of the inner box body; the anti-slip assembly realizes unidirectional movement of the lithium battery in the inner box body via an internal ratchet; and the buffer plate increases the friction between the lithium battery and the buffer plate via the buffer spring.

[0007] Furthermore, the anti-slip assembly includes: a mounting base installed on the inner wall of the inner box body; a skateboard installed inside the mounting base through a damping shock absorber; a plurality of mounting rods installed on the front side of the skateboard; and a pull rod installed on the side wall of the skateboard and extending toward the outer box body; the inner ratchet is installed on the mounting rod; a grab block is fixedly provided at the end of the pull rod, and the grab block is located outside the outer box body.

[0008] Furthermore, through holes adapted to the pull rod are provided on both side walls of the inner box body, and stepped holes adapted to the pull rod and the gripping block are provided on both side walls of the outer box body.

[0009] Furthermore, the mounting base is a rectangular parallelepiped structure with openings at the top and front, and an opening groove adapted to the slide plate is provided in the middle of the two side walls.

[0010] Furthermore, a mounting groove is formed at the middle of the top end of the slide plate, wherein a control push block is mounted on the mounting groove.

[0011] Furthermore, a partition is mounted on the top of the inner box body; wherein through holes adapted to the control push block and the lithium battery are respectively provided on both sides and the middle position of the upper surface of the partition.

[0012] Furthermore, a receiving cavity adapted to the lithium battery is formed between the inner box body, the anti-drop assembly and the buffer plate, and the receiving cavity has the same size as the through hole in the middle of the partition.

[0013] Furthermore, the buffer springs used to connect the buffer plate and the inner box body are in a plurality of groups; wherein the lengths of the plurality of groups of buffer springs increase sequentially from top to bottom when no deformation occurs.

[0014] Furthermore, support columns are arranged between the inner box and the outer box; wherein the support columns are evenly installed at the four corners of the outer box to achieve support installation of the inner box.

[0015] Furthermore, the inner box body is an inverted boss-shaped structure, and a heat dissipation cavity interconnected with each other is formed between the bottom outer wall of the inner box body and the outer walls of the outer box body and the support column, and ventilation holes are arranged on the bottom side wall of the outer box body corresponding to the heat dissipation cavity.

[0016] Compared with the prior art, the beneficial effects of the present invention are at least:

DETAILED DESCRIPTION

[0034] The present invention will be described in detail below in conjunction with the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0035] Example 1

[0036] Structure Figure 1-7 As shown, the utility model aims to provide a lithium battery box which can prevent lithium batteries from detaching, has buffering function and is easy to replace, so as to solve the problem in the prior art that lithium batteries are easily detached, damaged by collision and inconvenient to replace and repair. The utility model specifically includes an outer box body 4 and an inner box body 8.

[0037] A box cover 1 is snap-fitted onto the top of the outer box body 4, and connecting plates 2 are welded or integrated on both sides of the outer box body 4 and the box cover 1, and the two connecting plates 2 are connected to each other by bolts 10; supporting feet 5 are fixedly arranged at the four corners of the lower surface of the bottom end of the outer box body 4, and the supporting feet 5 are used to lift the outer box body 4 to facilitate ventilation through the ventilation holes 3, and the supporting feet 5 can be installed and removed according to actual needs; solid, rectangular support columns 11 are arranged at the four corners of the inner bottom of the outer box body 4, and the inner box body 8 is placed on the support columns 11, and a heat dissipation cavity that is interconnected is formed between the outer side wall of the bottom of the inner box body 8 and the outer side walls of the outer box body 4 and the support columns 11, and the bottom side wall of the outer box body 4 corresponding to the heat dissipation cavity is provided with ventilation holes 3, and the ventilation holes 3 realize circulation heat dissipation at the bottom of the inner box body 8 through heat exchange.

[0038] The inner box body 8 is a hollow inverted convex structure with an open top. Anti-slip components 9 are fixedly installed on the two opposite side walls of the inner top of the inner box body 8, and buffer plates 13 are installed on the two opposite side walls of the inner bottom of the inner box body 8 through buffer springs 12. The buffer plate 13 and the anti-slip component 9 are located on the same side of the inner box body 8; wherein, the buffer springs 12 used to connect the buffer plate 13 and the inner box body 8 are several groups, and the lengths of the several groups of buffer springs 12 increase from top to bottom in sequence when no deformation occurs, that is, when the lithium battery is not inserted, the buffer plate 13 is inclined, and then after the lithium battery is inserted, the buffer spring 12 located at the upper part is stretched and expanded, and the buffer spring 12 located at the lower part is compressed and deformed, and then under the action of pulling up and pressing down, the buffer spring 12 and the buffer plate 13 can achieve stable clamping and fixing of the lithium battery, and at the same time, the cooperation of the buffer spring 12 and the damping shock absorber 902 can prevent the lithium battery from shaking, slow down and offset the energy of the impact on the lithium battery, and prevent the lithium battery from colliding with the battery box and causing damage to the lithium battery. It is worth noting that, in order to improve adaptability, two sets of L-shaped plates with their bottoms hinged to each other can be used to clamp the lithium battery first, and then put it into the inner box 8 as a whole, and in order to improve heat dissipation, heat dissipation holes should be opened on the L-shaped plate. At the same time, the selection of the buffer spring 12 and the damping shock absorber 902 should be adapted to the lithium battery, the mounting base 903 and the inner box 8, and should have a high stiffness coefficient to prevent the lithium battery from shaking under the action of weak external force.

[0039] The anti-detachment assembly 9 includes a mounting base 903 mounted on the inner side wall of the inner box 8 by bolts. The mounting base 903 is a rectangular parallelepiped structure with openings at the upper end and the front side. An opening groove matching the slide plate 904 is opened in the middle of the two side walls. The slide plate 904 is slidably mounted on the opening groove. A damping shock absorber 902 is arranged between the slide plate 904 and the mounting base 903. Several groups of mounting rods 905 are mounted on the front side wall of the slide plate 904. Several groups of inner ratchets 906 are mounted on the mounting rods 905. A pawl matching the inner ratchets 906 is fixedly arranged on the mounting rods 905. The setting of the pawl enables the inner ratchet 906 to only realize one-way rotation on the mounting rod 905, thereby providing friction when the lithium battery is detached, thereby preventing the lithium battery from accidentally detaching. It is worth noting that the damping force of the damping shock absorber 902 should be kept large enough to avoid the lithium battery from detaching automatically due to accident.

[0040] An installation groove begins to be provided at the middle of the top of the slide plate 904, and a control push block 901 is snap-fitted and installed on the installation groove; a partition plate 6 is snap-fitted and installed on the top of the inner box body 8, and through holes compatible with the control push block 901 and the lithium battery are respectively provided on both sides and the middle position of the upper surface of the partition plate 6, and the through holes are used to control the reciprocating movement of the push block 901 and the insertion of the lithium battery; a pull rod 14 is installed in the middle of the back wall of the slide plate 904 by screws, one end of the pull rod 14 passes through the side walls of the inner box body 8 and the outer box body 4 and is located outside the outer box body 4, and the end of the pull rod 14 is threadedly connected with a gripping block 15, and through holes compatible with the pull rod 14 are provided on the two side walls of the inner box body 8, and through holes compatible with the pull rod 14 are provided on the two side walls of the outer box body 4. The step hole 16 is equipped with a through hole, and rubber sealing rings are provided on the through hole and the step hole 16; the gripping block 15 is a flat strip structure, which is located in the step hole 16 during use, and the gripping block 15 and the inside of the step hole 16 are provided with gaps for the gripping block 15 to grasp, and then the gripping block 15 pulls the pull rod 14 to drive the slide plate 904 to move along the open groove on the mounting base 903, wherein the pushing control push block 901 can assist the slide plate 904 in moving, and after the two slide plates 904 move to both sides, the outer wall of the inner ratchet 906 installed on the mounting rod 905 is disengaged from the outer wall of the lithium battery, and the lithium battery can be easily pulled out at this time, which can effectively reduce the workload of replacing and repairing the lithium battery.

[0041] A accommodating chamber 17 adapted to the lithium battery is formed between the inner box body 8, the anti-detachment component 9 and the buffer plate 13. The accommodating chamber 17 has the same size as the through hole in the middle position of the partition 6. After the lithium battery is placed in the accommodating chamber 17 through the partition 6, there is a small gap between the lithium battery and the side wall of the accommodating chamber 17. Specifically, the inner wall of the bottom of the inner box body 8, the front wall of the buffer plate 13, the two inner walls at the front end of the mounting base 903 and the outer wall of the inner ratchet 906 are all in contact with the outer wall of the lithium battery. At this time, in order to prevent the lithium battery from detaching autonomously, the unidirectional rotation force of the inner ratchet 906 and the upward and downward force of the buffer spring 12 at the rear of the buffer plate 13 can increase the friction between the inner ratchet 906 and the buffer plate 13 and the lithium battery, thereby reducing the risk of the lithium battery detaching autonomously. At the same time, the buffer spring 12 and the damping shock absorber 902 can also effectively slow down and offset the energy of the impact received by the lithium battery during transportation, preventing the lithium battery from shaking violently and being damaged by collision. It is worth noting that the gap between the lithium battery and the side wall of the accommodating cavity 17 should be controlled at 2 to 4 mm, which is convenient for placement and pulling out, and does not cause the lithium battery to shake drastically; at the same time, a number of rubber buffer pads should be set on the inner wall of the bottom of the inner box 8 and the two inner walls of the front end of the mounting base 903 to further reduce the collision energy between the lithium battery and the side wall of the accommodating cavity 17, thereby protecting the lithium battery and helping to improve the safety and stability of the lithium battery transportation process.

[0042] An automatic fire extinguishing device 7 is also fixed inside the inner box 8 by screws. The automatic fire extinguishing device 7 adopts a dry powder fire extinguisher with model number Sanqi'an 9020700022, which is used to automatically extinguish the fire in the inner box 8 when an emergency occurs.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole.
