Description

Technical Field

[0001] This utility model relates to the field of lithium battery protection board technology, specifically to a lithium battery protection board mounting structure. Background Technology

[0002] The installation structure of lithium battery protection boards mainly involves the design and optimization of lithium battery management systems, especially how to effectively protect lithium batteries from multiple risks such as overcurrent, overvoltage, and overtemperature during charging and discharging. Lithium batteries are widely used in portable electronic products, electric vehicles, and other fields due to their high energy density and long service life. However, due to the complexity of their internal chemical reactions, lithium batteries may experience problems such as thermal runaway, battery short circuit, overcharging, or over-discharging during use, which can lead to fires or explosions in severe cases. Therefore, the role of lithium battery protection boards is crucial, as they can effectively ensure the safety and stability of batteries during charging and discharging.

[0003] As disclosed in CN219086118U, a shock-absorbing mounting structure for a lithium battery protection board includes a battery rack. Side plates are fixedly connected to both ends of the battery rack. A lower mounting bracket is provided on one side of the outer wall of each side plate. Wing plates are fixedly connected to both sides of the lower mounting bracket. A rubber pad is fixedly connected to the side of each wing plate near the side plate. An upper mounting bracket is provided on the side of the lower mounting bracket away from the battery rack. Receiving grooves are provided on the sides of the upper and lower mounting brackets that are close to each other. This utility model utilizes the cooperation between the upper and lower mounting brackets, the buffer mechanism, and the insulating rubber cover. An insulating rubber cover is provided at the corner of the protection board, and the upper and lower mounting brackets are sleeved on its exterior. Simultaneously, a buffer mechanism is provided outside the mounting brackets. When the protection board and the lithium battery are working, the outer surface of the protection board is protected and buffered, preventing direct impact from the protection board and effectively protecting it from loosening and damage.

[0004] The aforementioned patented design can provide vibration reduction to a certain extent, but its vibration reduction effect is still insufficient when facing large vibrations or pressures. It is difficult to effectively cope with strong impacts or continuous high-pressure environments. In this case, the vibration reduction system cannot fully play its due role, resulting in the protective plate still being subjected to large impacts or displacements, affecting the overall stability and service life. Therefore, it is necessary to further optimize the vibration reduction structure and enhance its load-bearing capacity under high-intensity vibrations or pressures to ensure that the equipment can maintain good performance and reliability in various complex working environments. Utility Model Content

[0005] The purpose of this utility model is to provide a lithium battery protection board mounting structure, which has the advantage of efficient vibration reduction of the protection board and solves the problem that its vibration reduction effect is still insufficient when facing large vibrations or pressures.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a lithium battery protection board mounting structure, comprising a housing, two first fixing blocks fixedly connected to both sides of the top of the inner cavity of the housing, two fixing rods fixedly connected to the opposite side of the two first fixing blocks, and sliding brackets slidably connected to both ends of the two fixing rods, four sliding grooves opened at the top of the inner cavity of the housing, the sliding brackets slidably connected to the inner cavity of the sliding grooves, a first spring sleeved on the surface of the fixing rod, the two ends of the first springs respectively fixedly connected to the surface of the opposite side of the sliding bracket, a connecting rod rotatably connected to the top of the sliding bracket, the other ends of the two connecting rods rotatably connected to the fixing bracket, a mounting plate fixedly connected to the top of the four fixing brackets, a vibration damping pad fixedly connected to the top of the inner cavity of the mounting plate, and a protection board body provided on the top of the vibration damping pad.

[0021] As attached Figure 1 To be continued Figure 5As shown: This embodiment provides a lithium battery protection board mounting structure, including a housing 1. Two first fixing blocks 2 are fixedly connected to both sides of the top of the inner cavity of the housing 1. Two fixing rods 3 are fixedly connected to the opposite side of the two first fixing blocks 2. Sliding brackets 4 are slidably connected to both ends of the two fixing rods 3. Four sliding grooves 5 are opened at the top of the inner cavity of the housing 1. The sliding brackets 4 are slidably connected to the inner cavity of the sliding grooves 5. A first spring 6 is sleeved on the surface of the fixing rod 3. The two ends of the first spring 6 are respectively fixedly connected to the surface of the opposite side of the sliding bracket 4. A connecting rod 7 is rotatably connected to the top of the sliding bracket 4. The other ends of the two connecting rods 7 are rotatably connected to a fixing bracket 8. The top of the four fixing brackets 8 are fixedly connected to a mounting plate 9. A vibration damping pad 10 is fixedly connected to the top of the inner cavity of the mounting plate 9. A protection board body 11 is provided on the top of the vibration damping pad 10.

[0022] Specifically, a damper 12 is fixedly connected to the top of the outer casing 1, and two dampers 12 are symmetrically arranged.

[0023] In this embodiment, the damper 12 effectively absorbs and buffers the vibration and impact of the structure, rapidly absorbing and dispersing energy, thus reducing the impact of vibration on the internal structure.

[0024] Specifically, guide blocks 13 are fixedly connected to both sides of the sliding frame 4, and guide grooves 14 are opened on both sides of the sliding groove 5. The guide blocks 13 are slidably connected to the inner cavity of the guide grooves 14.

[0025] In this embodiment, the guide block 13 and the guide groove 14 work together to guide and limit the movement. When pressure is applied to the sliding frame 4, the guide blocks 13 on both sides of the sliding frame 4 will slide smoothly in the inner cavity of the guide groove 14, ensuring the stable movement of the sliding frame 4 and effectively avoiding instability caused by improper displacement or offset, thus improving the reliability and safety of the overall structure.

[0026] Specifically, two second springs 15 are fixedly connected to both sides of the inner wall of the outer casing 1, and two second fixing blocks 16 are fixedly connected to both sides of the mounting plate 9. One end of the second spring 15 is fixedly connected to the second fixing block 16.

[0027] In this embodiment, the second spring 15 and the second fixing block 16 work together to achieve a certain vibration reduction effect. The second spring 15 can dynamically adjust its compression and release according to the external vibration, thereby buffering and absorbing vibration and avoiding damage to sensitive components caused by vibration.

[0028] Specifically, grooves are provided on the inner walls of both sides of the fixing frame 8, and a third spring 17 is fixedly connected to the inner cavity of the groove. The other end of the third spring 17 is fixedly connected to a limit block 18.

[0029] In this embodiment, through the combined use of the groove, the third spring 17 and the limiting block 18, the limiting block 18 can effectively limit and block the protective plate body 11, ensuring that the protective plate body 11 will not shake or detach during use, thereby ensuring the stability and reliability of the structure and reducing the risk of damage caused by unexpected factors.

[0030] The working principle and usage process of this utility model are as follows: The user places the protective plate body 11 on the surface of the limiting block 18. Utilizing the inclined design of the top surface of the limiting block 18, the protective plate body 11 applies pressure to the limiting block 18, causing the limiting block 18 to retract the third spring 17 fixedly connected to it. This allows the limiting block 18 to enter the grooves on both sides of the mounting plate 9. Thus, the protective plate body 11 can smoothly enter the inner cavity of the mounting plate 9. Under the restoring elasticity of the third spring 17, the limiting block 18 effectively limits and blocks the protective plate body 11, ensuring that the protective plate body 11 will not shake or detach during use. To enhance stability, the bottom of the mounting plate 9 is also equipped with... The vibration damping pad 10 has good vibration damping and anti-slip functions. When pressure is applied to the protective plate body 11, the protective plate body 11 will drive the mounting plate 9 to press down. At this time, the second spring 15 and the second fixing block 16 set on both sides of the mounting plate 9 work together to provide a preliminary vibration damping effect. As the mounting plate 9 continues to press down, the four fixing brackets 8 at the bottom are squeezed downward. The fixing brackets 8 are rotatably connected to the connecting rod 7, and the connecting rod 7 is rotatably connected to the sliding bracket 4, so that the sliding bracket 4 slides on the surface of the fixing rod 3, which exerts a squeezing effect on the first spring 6. Under the rebound action of the first spring 6 itself, a more efficient vibration damping effect is provided, and the pressure is effectively decomposed, thereby ensuring that the protective plate body 11 receives good vibration damping protection.

[0031] It should be noted that in this paper, relational terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.

[0032] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Those skilled in the art to which this invention pertains can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of this invention shall be determined by the claims.
