Description

Technical Field

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

[0002] As a core component ensuring the safe operation of lithium batteries, the lithium battery protection board often faces significant shaking and impact during handling and transportation after production, which can easily lead to component detachment or poor circuit contact. After installation and use, the environment tends to stabilize, requiring the protection board to remain firmly installed to prevent minor displacement from affecting the reliability of electrical connections. However, existing lithium battery protection board installation structures have significant drawbacks: most structures only emphasize either shock absorption or fixation, failing to meet the needs of both scenarios. Structures with only shock absorption lack effective locking mechanisms during use, making the protection board prone to loosening; structures that only emphasize fixation lack cushioning designs during handling and transportation, making the protection board susceptible to vibration damage. Furthermore, the few structures that attempt to combine both functions require manual disassembly and adjustment of components to switch states, which is cumbersome and inefficient, making it difficult to adapt to the full range of needs from lithium battery production and transportation to installation and use, and failing to meet the dual requirements of convenience and safety in practical applications. Utility Model Content

[0003] To solve the above technical problems, this utility model provides a shock-absorbing mounting structure for a lithium battery protection board, including a shock-absorbing rubber plate attached to the bottom of the protection board and a support plate located below the shock-absorbing rubber plate. A lower electromagnetic component is installed on the upper surface of each end of the support plate, and an upper electromagnetic component is installed on the lower surface of each end of the shock-absorbing rubber plate. The upper electromagnetic components are located directly above the lower electromagnetic components. Limiting rods are connected to the four corners of the support plate and the shock-absorbing rubber plate. The spacing between the shock-absorbing rubber plate and the support plate is controlled by the change of the magnetic field of the upper and lower electromagnetic components.

[0004] A limiting mechanism is also provided between the upper surface of the support plate and the lower surface of the shock-absorbing rubber plate. After the upper and lower electromagnetic components are attached, the spacing between the support plate and the shock-absorbing rubber plate is controlled by the limiting mechanism.

Detailed Implementation

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0020] like Figure 1-4 The illustrated shock-absorbing mounting structure for a lithium battery protection board includes a shock-absorbing rubber plate 2 attached to the bottom of a protection board 1 and a support plate 3 located below the shock-absorbing rubber plate 2. Lower electromagnetic components are mounted on the upper surfaces of both ends of the support plate 3, and upper electromagnetic components are mounted on the lower surfaces of both ends of the shock-absorbing rubber plate 2. The upper electromagnetic components are positioned directly above the lower electromagnetic components. Limiting rods are connected to the four corners of the support plate 3 and the shock-absorbing rubber plate 2. The spacing between the shock-absorbing rubber plate 2 and the support plate 3 is controlled by the magnetic field changes of the upper and lower electromagnetic components. A limiting mechanism is also provided between the upper surface of the support plate 3 and the lower surface of the shock-absorbing rubber plate 2. After the upper and lower electromagnetic components are attached, the spacing between the support plate 3 and the shock-absorbing rubber plate 2 is controlled by the limiting mechanism. By controlling the energization state of the electromagnetic components, two different equipment states are achieved: one with good shock absorption, and the other for more stable and convenient operation and heat dissipation.

[0021] Based on the above, the shock-absorbing rubber plate 2 is first attached to the bottom of the protective plate 1 to provide basic elastic buffer for the protective plate 1; the support plate 3 serves as the bottom support, and the lower electromagnetic components at both ends of the support plate 3 correspond vertically to the upper electromagnetic components at both ends of the shock-absorbing rubber plate 2. By changing the current direction of the upper and lower electromagnetic components, the same current generates repulsion, the opposite current generates attraction, or the power is cut off, the distance between the shock-absorbing rubber plate 2 and the support plate 3 can be controlled. In the repulsion state, a shock-absorbing space is formed, and in the attraction or power-off state, a tight fit is achieved; the four corner limit rods connect the two to prevent lateral displacement; the limit mechanism further locks the distance after the fit to ensure stability; the whole system achieves the switching between shock absorption and fixation states through the cooperation of electromagnetic distance control and mechanical limit.

[0022] Among them, mounting blocks 22 are installed at the four corners of the support plate 3. The mounting blocks 22 have through screw holes, and the support plate 3 is fixedly installed inside the battery casing by screws and other components.

[0023] Furthermore, it can switch working states without manual disassembly, adapting to both transport and shock absorption scenarios and fixed use scenarios. The basic structure reserves space for future functional expansion, making it highly practical.

[0024] The lower electromagnetic component includes a lower electromagnet 4 fixed on the upper surface of the support plate 3 and a first protective cover 5 covering the lower electromagnet 4. Several protruding lower limit rods 6 are installed in the middle of the upper surface of the first protective cover 5, and lower rubber pads 7 are attached to the upper surface of the first protective cover 5 located on both sides of the lower limit rods 6.

[0025] Based on the above, the lower electromagnet 4 is fixed on the support plate 3 to provide magnetic force for spacing control; the first protective cover 5 completely covers the lower electromagnet 4 to avoid impact and damage to the electromagnet; the lower limit rod 6 on the first protective cover 5 is used to cooperate with the upper limit rod 10 of the upper electromagnet in the fit state to achieve precise positioning; the lower rubber pad 7 contacts the upper rubber pad 11 when in the fit, and buffers very slight vibrations through its own elasticity, while avoiding wear caused by direct friction between metal parts.

[0026] The upper electromagnetic component includes an upper electromagnet 8 fixed to the lower surface of the shock-absorbing rubber plate 2 and a second protective cover 9 covering the lower part of the upper electromagnet 8. Several protruding upper limit rods 10 are installed in the middle of the lower surface of the second protective cover 9, and upper rubber pads 11 are attached to the lower surface of the second protective cover 9 on both sides of the upper limit rods 10.

[0027] Based on the above, the upper electromagnet 8 is fixed to the lower surface of the shock-absorbing rubber plate 2, corresponding to the lower electromagnet 4, and drives the shock-absorbing rubber plate 2 to move up and down through changes in the magnetic field; the second protective cover 9 covers the upper electromagnet 8, providing protection against impact; the upper limit rod 10 on the lower surface of the second protective cover 9 corresponds to the lower limit rod 6, and can be inserted into the adjacent gap of the lower limit rod 6 when they are attached, limiting the lateral sliding of the shock-absorbing rubber plate 2 and the support plate 3; the upper rubber pad 11 corresponds to the lower rubber pad 7, and they are pressed against each other when they are attached, further enhancing the cushioning effect and the sealing performance.

[0028] Furthermore, the structure is symmetrical with the lower electromagnetic component to ensure uniform magnetic force transmission and precise positioning; the second protective cover 9 protects the upper electromagnet 8, the upper limit rod 10 and the lower limit rod 6 cooperate to achieve dual positioning, the upper rubber pad 11 and the lower rubber pad 7 work together to improve the buffering and anti-wear effect, and the upper and lower electromagnetic components are closely matched and have complementary functions.

[0029] Several upper limit rods 10 are located directly above several lower limit rods 6. After the upper electromagnetic component and the lower electromagnetic component are attached, the lower rubber pad 7 and the upper rubber pad 11 are attached to each other, and the several upper limit rods 10 and the several lower limit rods 6 are respectively inserted into the adjacent gaps.

[0030] Based on the above, the positional relationship between the upper limit rod 10 and the lower limit rod 6 ensures that the upper and lower electromagnetic components can be precisely aligned when they are attached. After attachment, the upper limit rod 10 is inserted into the adjacent gap of the lower limit rod 6, and the lower limit rod 6 is simultaneously inserted into the adjacent gap of the upper limit rod 10, forming a cross-insertion structure, which completely restricts the relative sliding of the shock-absorbing rubber plate 2 and the support plate 3 in the horizontal direction. At the same time, the lower rubber pad 7 and the upper rubber pad 11 are completely attached, and the elastic deformation of the rubber fills the tiny gaps, which not only buffers the micro-vibrations of the environment, but also avoids the direct contact of the metal limit rods to generate noise or wear. The structural stability is greatly improved, and no additional space is occupied.

[0031] The limiting rod includes a connecting rod 12 fixed to the lower surface of the shock-absorbing rubber plate 2 and a connecting pipe 13 fixed to the upper surface of the support plate 3. A piston block 14 that moves back and forth is provided inside the connecting pipe 13. The bottom end of the connecting rod 12 passes through the connecting pipe 13 and is fixedly connected to the piston block 14.

[0032] Based on the above, the top end of the connecting rod 12 is fixed to the lower surface of the shock-absorbing rubber plate 2, and the bottom end is connected to the piston block 14 inside the connecting tube 13. The connecting tube 13 is fixed to the upper surface of the support plate 3, forming a vertical connection of "shock-absorbing rubber plate 2-connecting rod 12-piston block 14-connecting tube 13-support plate 3". When the device is in the shock-absorbing state, the electromagnetic repulsion causes the shock-absorbing rubber plate 2 to move up and down. The connecting rod 12 drives the piston block 14 to slide back and forth inside the connecting tube 13. The friction between the piston block 14 and the inner wall of the connecting tube 13 can consume some of the vibration energy. At the same time, the connecting tube 13 restricts the lateral displacement of the connecting rod 12, thereby preventing the shock-absorbing rubber plate 2 and the protective plate 1 from shaking laterally. Meanwhile, the piston block 14 moves inside the connecting tube 13 to prevent the connecting rod 12 from separating and falling off from the connecting tube 13.

[0033] The limiting mechanism includes a first connecting plate 15 fixed to the lower surface of the shock-absorbing rubber plate 2 and a second connecting plate 16 fixed to the upper surface of the support plate 3. The bottom end of the first connecting plate 15 and the top end of the second connecting plate 16 are provided with through limiting holes 17. After the upper electromagnetic component and the lower electromagnetic component are attached, the limiting holes 17 on the first connecting plate 15 and the second connecting plate 16 coincide.

[0034] Based on the above, the first connecting plate 15 moves with the shock-absorbing rubber plate 2, and the second connecting plate 16 is fixed on the support plate 3. When the upper and lower electromagnetic components are in contact, the shock-absorbing rubber plate 2 drives the first connecting plate 15 to move down, so that the first connecting plate 15 and the second connecting plate 16 are aligned, and the limiting holes 17 of the two are precisely overlapped. The overlapping limiting holes 17 provide an insertion channel for the subsequent locking structure micro servo push rod 19, ensuring accurate positioning during locking and preventing relative displacement between the shock-absorbing rubber plate 2 and the support plate 3 before locking.

[0035] A support frame 18 is installed on the upper surface of the support plate 3. A micro servo push rod 19 is installed at the top of the support frame 18. The output shaft of the micro servo push rod 19 faces the limiting hole 17 and matches the inner wall size of the limiting hole 17.

[0036] Based on the above, the support frame 18 is fixed on the support plate 3 to provide stable support for the micro servo push rod 19. When the limiting hole 17 of the first connecting plate 15 and the second connecting plate 16 coincides, the micro servo push rod 19 is activated, and its output shaft extends in the direction toward the limiting hole 17 and is inserted into the overlapping limiting hole 17. The output shaft matches the inner wall size of the limiting hole 17. After insertion, it can rigidly restrict the relative movement of the first connecting plate 15 and the second connecting plate 16, thereby locking the distance between the shock-absorbing rubber plate 2 and the support plate 3 to ensure a stable and unloose state.

[0037] Furthermore, the rigid locking method of the miniature servo push rod 19 is more reliable than the elastic locking method, and can completely eliminate the gap change caused by vibration during use; the output shaft and the limit hole 17 are matched in size to avoid shaking after locking; the support frame 18 ensures the stability of the push rod when it is working; the overall locking structure has fast response and high reliability.

[0038] The shock-absorbing rubber plate 2 has a through hole 20 in the middle, and the support plate 3 has a cooling fan 21 embedded in the middle, with the cooling fan 21 located directly below the through hole 20.

[0039] Based on the above, the cooling fan 21 is embedded in the middle of the support plate 3. After being powered on, it can draw in cold air from the outside. The through hole 20 in the middle of the shock-absorbing rubber plate 2 corresponds to the cooling fan 21. The cold air flows upward through the cooling fan 21 and reaches the bottom of the protection plate 1 through the through hole 20. It exchanges heat with the protection plate 1 and takes away the heat generated by the protection plate 1 during operation. The air after heat exchange naturally diffuses upward and is discharged, forming a heat dissipation path of "drawing in cold air - dissipating heat - dissipating hot air". The direct correspondence between the through hole 20 and the cooling fan 21 ensures that the airflow is unobstructed and the heat dissipation efficiency is maximized.

[0040] Furthermore, heat dissipation is integrated into the shock absorption and fixing structure without requiring additional external space for the device; the through hole 20 corresponds precisely to the cooling fan 21, avoiding the shock absorption plate 2 from blocking airflow and ensuring heat dissipation efficiency; compared with the traditional design of "shock absorption structure blocking heat dissipation", this structure achieves non-conflicting synergy between shock absorption and heat dissipation, extending the service life of the protection plate 1.

[0041] Based on the above, this structure has two states. In the first state, when the device is in handling or transport mode, the upper and lower electromagnetic components are energized, generating a repulsive magnetic field in the same direction. This repulsive force pushes the shock-absorbing rubber plate 2 at the bottom of the protective plate 1 away from the support plate 3, forming a shock-absorbing gap that can be adjusted by the current intensity. The greater the current, the stronger the repulsive force and the larger the gap, laying the foundation for buffering vibrations. In the second state, when the upper and lower electromagnetic components are de-energized or the current direction is switched, the magnetic repulsive force disappears and transforms into an opposite magnetic attraction force, pulling the shock-absorbing rubber plate 2 downwards until the upper and lower electromagnetic components are completely attached. The first connecting plate 15 fixed to the shock-absorbing rubber plate 2 aligns with the second connecting plate 16 fixed to the support plate 3, and their limiting holes 17 completely overlap. The miniature servo push rod 19 at the top of the support frame 18 on the support plate 3 is activated, and its output shaft is inserted into the overlapping limit hole 17 to rigidly lock the distance between the shock-absorbing rubber plate 2 and the support plate 3, completely preventing structural loosening during use. The cooling fan 21 embedded in the middle of the support plate 3 is activated, and the external cold air flows upward through the fan and reaches the bottom of the protection plate 1 through the through hole 20 in the middle of the shock-absorbing rubber plate 2, quickly carrying away the heat generated by the protection plate 1 during operation and avoiding the shock-absorbing structure from blocking the heat dissipation efficiency.

[0042] Furthermore, this device requires no manual disassembly or adjustment. It can quickly switch between "shock-absorbing during transport" and "fixed use" simply by controlling the current of the upper and lower electromagnetic components. During transport, it relies on electromagnetic repulsion and multiple shock absorption mechanisms to buffer bumps. During use, it uses electromagnetic attraction and servo push rod locking to ensure stability. It perfectly adapts to the full range of lithium battery needs from production and transportation to installation and use. It is easy to operate and highly efficient.

All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model.
