Description

Technical Field

[0001] This utility model relates to the field of new energy battery box technology, and in particular to a drop-resistant battery structure. Background Technology

[0002] A battery is a device that converts chemical or physical energy into electrical energy. However, when traditional batteries are subjected to external impacts such as drops or collisions, the internal electrodes and electrolytes will be damaged, and short circuits may even occur. To address this, people have developed drop-resistant battery structures. By using springs and piston structures to fix the electrodes and reduce internal shaking, and then using a high-toughness drop-resistant shell to disperse the impact force, not only is the safety of the battery ensured in extreme environments, but the battery life is also significantly extended.

[0003] A search revealed Chinese patent publication number CN217468629U, which discloses a shock-resistant and scratch-resistant new energy battery box. The box includes a body, a spring-loaded frame fixedly installed on the bottom wall of the body, a compression plate inside the spring-loaded frame, and a support rod movably connected to the top of the compression plate via a hinge. A fixed frame is located inside the body, and telescopic rods are movably connected to both sides of the fixed frame, near its top and bottom ends, via hinges. A first spring is fixedly sleeved on the outside of each telescopic rod. Rotating rods are located on both sides of the body, and the output ends of the rotating rods pass through the side walls of the body and are fixedly connected to a fixing device. This utility model, through the combination of the above-mentioned structures, achieves buffering of the impact force generated during the battery box's drop, thereby providing cushioning protection for the battery. It can also fix different types of batteries, making it more applicable and convenient for users. Furthermore, the anti-scratch sleeve can isolate the box from the outside environment, thereby reducing the risk of box wear. However, in actual use, the existing device uses multiple springs and T-shaped moving rods for shock absorption. Due to its overly complex structure, the battery's internal components may be damaged when subjected to a major impact, leading to a short circuit. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a drop-resistant battery structure, aiming to improve the problem of too many drop-resistant structural components in existing batteries.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a drop-resistant battery structure, comprising a composite protective shell, an electrode disposed on the inner wall of the composite protective shell, a buffer mechanism disposed on the inner wall of the composite protective shell, a limiting mechanism disposed on the outer wall of the electrode, and a sealing mechanism disposed on the top of the composite protective shell;

[0006] The buffer mechanism includes two three-dimensional mesh buffer plates, with their opposite sides fixedly connected to the front and rear sides of the inner wall of the composite protective shell. Two three-dimensional mesh buffer plates are fixedly connected to the left and right sides of the inner wall of the composite protective shell. Adaptive pressure dispersion groups are fixedly connected to the upper and lower sides of the electrode. Connecting blocks are fixedly connected to the opposite sides of the two adaptive pressure dispersion groups. Piezoelectric sensors are fixedly connected to the upper and lower sides of the electrode. Square sleeves are fixedly connected to the upper and lower sides of the electrode. Positioning plates are slidably connected to the inner walls of the two square sleeves. Airbags are fixedly connected to the opposite sides of the two positioning plates. Two check valves are fixedly connected to the outer walls of the two airbags. An inflation assembly is provided on the outer wall of the electrode.

[0007] Through the above technical solution: the composite protective shell first absorbs the impact force on the battery with its own protective material, and then the three-dimensional mesh buffer plate one and three-dimensional mesh buffer plate two further reduce the vibration force transmitted from the outside. At the same time, the pressure sensor detects the pressure between the electrode and the positioning plate in real time. When the pressure is too high, the inflation component is activated to inflate the airbag, so that the airbag can fill the space between the composite protective shell and the positioning plate, reducing the remaining impact force, avoiding battery damage, and increasing the battery's drop resistance.

[0008] As a further description of the above technical solution:

[0009] The inflation assembly includes two miniature pressure pumps, with each of the two miniature pressure pumps fixedly connected to the upper and lower sides of the electrode, respectively. Each of the upper and lower sides of the electrode is fixedly connected to a miniature gas storage tank, and the left end of each of the two miniature gas storage tanks is connected to a gas supply pipe.

[0010] The above technical solution involves activating two miniature pressure air pumps to extract and compress the surrounding air. The compressed air is then stored in a miniature air tank. By controlling the inflow and outflow of compressed air, the compressed air flows into the airbag through the air supply pipe, thereby enabling the airbag to perform its shock absorption function.

[0011] As a further description of the above technical solution:

[0012] The limiting mechanism includes multiple sealing blocks, each of which is fixedly connected to the outer wall of the three-dimensional mesh buffer plate II on one adjacent side. Each of the multiple sealing blocks has a sliding groove on one adjacent side, and multiple springs are fixedly connected to the opposite sides of the two positioning plates.

[0013] Through the above technical solution: the positioning plate moves up and down when the vibration is relieved in the device, and slides in the groove on the inner wall of the sealing block. The groove can provide guidance and limit for the displacement of the positioning plate, preventing the positioning plate from detaching from the electrode and the directional sleeve. Then the positioning plate moves and resets under the cooperation of the spring and the adaptive pressure dispersion group.

[0014] As a further description of the above technical solution:

[0015] The sealing mechanism includes a cover, the bottom of which is slidably connected to the top of the composite protective shell. The top of the composite protective shell has multiple threaded grooves, and the inner walls of the multiple threaded grooves are threaded with fixing bolts.

[0016] The above technical solution involves placing the cover on top of the composite protective shell, and then threading bolts through the cover and connecting them to the corresponding threaded grooves to completely secure the cover, thereby sealing the outer wall of the battery and enhancing its shock absorption capability.

[0017] As a further description of the above technical solution:

[0018] The outer wall of the composite protective shell has multiple heat dissipation holes, and the two three-dimensional mesh buffer plates and the two three-dimensional mesh buffer plates are symmetrically distributed.

[0019] The above technical solution dissipates the high heat generated by the electrodes through multiple heat dissipation holes, reducing the internal heat of the battery. The symmetrical distribution of the two three-dimensional mesh buffer plates and the two three-dimensional mesh buffer plates increases the overall stability of the battery and prevents the battery from shaking.

[0020] As a further description of the above technical solution:

[0021] A vent is provided on the right side of the positioning plate, and the inner wall of the vent is larger than the outer wall of the air supply pipe.

[0022] The above technical solution involves opening a vent hole on the right side of the outer wall of the positioning plate, allowing the air supply pipe to enter the upper space through the vent hole.

[0023] As a further description of the above technical solution:

[0024] Both the upper and lower sides of the electrode are fixedly connected to shock-absorbing pads, and the two shock-absorbing pads are respectively fixedly connected to the adjacent sides of the two square sleeves on opposite sides.

[0025] The above technical solution involves adding a shock-absorbing pad between the electrode and the square sleeve, which can reduce vibration when the battery experiences significant vibration, thus preventing damage to the electrode.

[0026] As a further description of the above technical solution:

[0027] Temperature detectors are fixedly connected to both the upper and lower sides of the electrode, and buzzers are fixedly connected to both the upper and lower sides of the electrode.

[0028] Through the above technical solution, the temperature sensor inside the device can detect the temperature inside the battery in real time and make the buzzer sound when the temperature is too high.

[0029] This utility model has the following beneficial effects:

[0030] In this invention, the composite protective shell and three-dimensional mesh buffer plate initially absorb the impact force generated by the impact. For the impact force that is not completely absorbed, the micro hydraulic damper and airbag in the adaptive pressure dispersion group can absorb the impact force again. The impact force is resolved layer by layer through the three-layer buffer structure, which greatly reduces the risk of damage to the small electrode. After the shock absorption is completed, the components inside the device begin to reset, which can provide continuous protection for the battery and effectively improve the reliability and safety of the battery when it is subjected to impact.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Reference Figure 2 , Figure 3 and Figure 4 The present invention provides an embodiment of a drop-resistant battery structure, comprising a composite protective shell 1, an electrode 2 disposed on the inner wall of the composite protective shell 1, the electrode 2 serving as the main power generation component of the battery, a buffer mechanism 3 disposed on the inner wall of the composite protective shell 1, the buffer mechanism 3 being used to absorb shock when the battery is impacted, preventing damage to the electrode 2, a limiting mechanism 4 disposed on the outer wall of the electrode 2, the limiting mechanism 4 being used to limit the position of two positioning plates 307 inside the device, thereby limiting the electrode 2, and a sealing mechanism 5 disposed on the top of the composite protective shell 1, the sealing mechanism 5 being used to keep the battery in a sealed state;

[0040] The buffer mechanism 3 includes two three-dimensional mesh buffer plates 301. The two three-dimensional mesh buffer plates 301 are fixedly connected to the front and rear sides of the inner wall of the composite protective shell 1, respectively, with the opposite sides of the two three-dimensional mesh buffer plates 301. Three-dimensional mesh buffer plates 302 are fixedly connected to the left and right sides of the inner wall of the composite protective shell 1. The two three-dimensional mesh buffer plates 301 and 302 are used to dampen the device when it is impacted, preventing damage to the electrode 2 inside the device. The three-dimensional mesh buffer plates 302 are slightly shorter than the three-dimensional mesh buffer plates 301, with the shorter part used to provide installation space for the sealing block 401. Adaptive pressure dispersion groups 304 are fixedly connected to the upper and lower sides of the electrode 2. The adaptive pressure dispersion groups 304 contain six micro hydraulic dampers to reduce vibration. Connecting blocks 305 are fixedly connected to the opposite sides of the two adaptive pressure dispersion groups 304. One end of the connecting block 305 is connected to the corresponding positioning plate 307. Piezoelectric sensors 306 are fixedly connected to the upper and lower sides of the electrode 2. 306 is used to detect the impact force received by the device, and then to determine whether the inflation assembly 310 is operating based on the test results. Square sleeves 303 are fixedly connected to both the upper and lower sides of electrode 2. The square sleeves 303 provide space for the adaptive pressure dispersion group 304, piezoelectric sensor 306, and inflation assembly 310. Positioning plates 307 are slidably connected to the inner walls of both square sleeves 303. The positioning plates 307 are used to position the adaptive pressure dispersion group 304, piezoelectric sensor 306, and inflation assembly 310. To limit the impact, airbags 308 are fixedly connected to the opposite sides of the two positioning plates 307. The airbags 308 fill the space between the composite protective shell 1 and the positioning plates 307, which can further reduce shock. Two check valves 309 are fixedly connected to the outer walls of the two airbags 308. The check valves 309 can prevent the air from flowing back into the airbags 308. An inflation component 310 is provided on the outer wall of the electrode 2. The inflation component 310 provides air to the airbags 308, so that the airbags 308 can expand and reduce shock.

[0041] Specifically, when the battery is impacted, the composite protective shell 1 first resists the external impact force. The three-dimensional mesh buffer plate 301 and the three-dimensional mesh buffer plate 302 on the inner wall of the composite protective shell 1 undergo elastic deformation to initially absorb the kinetic energy generated by the impact and slow down the transmission of the impact force to the electrode 2. When the composite protective shell 1 and the three-dimensional mesh buffer plate do not completely offset the impact force, the piezoelectric sensors 306 on the upper and lower sides of the electrode 2 detect the impact force exceeding the threshold and trigger the inflation component 310. At the same time, the adaptive pressure dispersion group 304... The miniature hydraulic damper in the middle starts to operate, using the resistance of hydraulic oil to further reduce vibration, while the inflation component 310 quickly inflates the airbag 308 with gas. The airbag 308 expands and fills the gap between the composite protective shell 1 and the positioning plate 307, forming a buffer layer to further enhance the buffering effect. After the impact, the three-dimensional mesh buffer plate returns to its original shape with its own elasticity, the airbag 308 slowly deflates through the check valve 309, and the positioning plate 307 returns to its initial position under the action of the miniature hydraulic damper and the spring 403, preparing for the next impact.

[0042] Reference Figure 3 , Figure 4 and Figure 5 The inflation assembly 310 includes two miniature pressure pumps 3101, which are used to extract and compress air. The adjacent sides of the two miniature pressure pumps 3101 are fixedly connected to the upper and lower sides of the electrode 2, respectively. Miniature air storage tanks 3102 are fixedly connected to the upper and lower sides of the electrode 2. The miniature air storage tanks 3102 are used to store compressed air. The left ends of the two miniature air storage tanks 3102 are connected to air supply pipes 3103, which inflate the airbag 308 through the air supply pipes 3103.

[0043] Specifically, when the battery is impacted and the impact force is too large, the piezoelectric sensor 306 detects the impact force, causing two miniature pressure pumps 3101 to start synchronously, drawing air from inside the battery, compressing the air and injecting it into the miniature air tank 3102. The pressure inside the air tank rises rapidly, the solenoid valve on the air supply pipe 3103 opens, and high-pressure air is quickly injected into the airbag 308 through the air supply pipe 3103. The airbag 308 quickly expands and fills the gap between the positioning plate 307 and the composite protective shell 1. The check valve 309 ensures that the high-pressure air in the airbag 308 does not flow back. The miniature pressure pumps 3101 continue to work until the pressure in the airbag 308 reaches the safety threshold and then stops. The check valve 309 opens, and the air in the airbag 308 is slowly discharged. The positioning plate 307 returns to its original position under the action of the miniature hydraulic damper and the spring 403, so that the inflation component 310 returns to the standby state.

[0044] Reference Figure 1 , Figure 2 and Figure 3The limiting mechanism 4 includes multiple sealing blocks 401. Each adjacent side of the sealing blocks 401 is fixedly connected to the outer wall of the three-dimensional mesh buffer plate 302. Each adjacent side of the sealing blocks 401 has a sliding groove 402. The positioning plate 307 slides within the sliding groove 402, limiting the position of the positioning plate 307. Multiple springs 403 are fixedly connected to the opposite sides of the two positioning plates 307. The multiple springs 403 can reduce vibration and, in conjunction with the adaptive pressure dispersion group 304, limit the position of the positioning plate 307. The sealing mechanism 5 includes a cover 501. 01 and the composite protective shell 1 can form a sealed space. The bottom of the cover 501 is slidably connected to the top of the composite protective shell 1. The top of the composite protective shell 1 is provided with multiple threaded grooves 502. The inner walls of the multiple threaded grooves 502 are all threaded with fixing bolts 503. The cover 501 is fixed by the multiple threaded grooves 502 and fixing bolts 503. The outer wall of the composite protective shell 1 is provided with multiple heat dissipation holes 6. The heat dissipation holes 6 are used to dissipate heat from the heat-generating components inside the device. The two three-dimensional mesh buffer plates 1 and 2 three-dimensional mesh buffer plates 302 are symmetrically distributed.

[0045] Specifically, when the battery is impacted and the internal structure of the drop-resistant battery is in operation, the positioning plate 307 is subjected to the force of the adaptive pressure dispersion group 304 and the spring 403, and slides up and down in the groove 402 of the sealing block 401. The groove 402 restricts the movement trajectory of the positioning plate 307 and prevents the groove 402 from shifting or misaligning. When the positioning plate 307 slides, the spring 403 absorbs the vibration energy through compression or stretching deformation, and works with the adaptive pressure dispersion group 304 to reset the positioning plate 307 after the vibration weakens. When installing the battery, the cover 501 is placed on top of the composite protective shell 1, aligned with the threaded groove 502, and the fixing bolt 503 is screwed in to make the cover 501 tightly connected to the composite protective shell 1, forming a sealed space to protect the internal components of the battery from dust and moisture. During the charging and discharging process of the battery, the electrode 2 will generate heat, which is transferred to the composite protective shell 1 through the air and then dissipated to the external environment through the heat dissipation holes 6 on the shell, accelerating air convection and preventing the battery from being affected by excessive temperature, thus extending its performance and service life.

[0046] Reference Figure 3 and Figure 4A vent 3104 is provided on the right side of the positioning plate 307. The vent 3104 is used to allow the air supply pipe 3103 to pass directly through the positioning plate 307, avoiding the need to extend the air supply pipe 3103 to connect to the airbag 308. The inner wall shape and size of the vent 3104 are larger than the outer wall shape and size of the air supply pipe 3103. Shock-absorbing pads 311 are fixedly connected to the upper and lower sides of the electrode 2. The two shock-absorbing pads 311 are fixedly connected to the adjacent sides of the two square sleeves 303 respectively. The shock-absorbing pads 311 can increase the stability of the connection between the square sleeves 303 and the electrode 2 when the battery is subjected to large vibrations, thus preventing damage to the battery. Temperature sensors 7 are fixedly connected to the upper and lower sides of the electrode 2. Temperature sensors 7 can detect the temperature inside the device. Buzzers 8 are fixedly connected to the upper and lower sides of the electrode 2. Buzzers 8 can sound an alarm when the temperature inside the battery is too high, thus reminding the staff to take remedial measures.

[0047] Specifically, when the battery is impacted, the vent 3104 allows the air supply pipe 3103 to pass directly through the positioning plate 307, shortening the inflation path and ensuring that the airbag 308 inflates quickly. The inner diameter of the vent 3104 is slightly larger than the outer diameter of the air supply pipe 3103, preventing pipe bending and thus avoiding obstruction of airflow. At the same time, the shock-absorbing pad 311 uses its own elasticity between the square sleeve 303 and the electrode 2 to reduce the loosening of components caused by vibration. During battery operation, the temperature sensor 7 can monitor the temperature inside the battery in real time. When the temperature exceeds the threshold, the buzzer 8 sounds an alarm to remind the staff to cool down the battery in time, preventing accidents caused by high temperature and improving the battery's buffer response speed and operational safety.

[0048] Working principle: When the battery is impacted, the composite protective shell 1 first acts as a buffer against external impact. The three-dimensional mesh buffer plate 301 and the three-dimensional mesh buffer plate 302 on the inner wall of the shell convert the kinetic energy generated by the impact into elastic potential energy through their own elastic deformation, thus initially reducing the impact force and the impact on the electrode 2. When the composite protective shell 1 and the three-dimensional mesh buffer plates cannot completely dissipate the impact force, the piezoelectric sensor 306 sensitively detects the impact force and triggers the inflation component 310 to start. At the same time, the micro hydraulic damper in the adaptive pressure dispersion group 304 further slows down the vibration and reduces the impact. The force is determined by the pressure, and the inflation component 310 quickly inflates the airbag 308, causing the airbag 308 to expand rapidly, filling the gap between the composite protective shell 1 and the positioning plate 307 to form a buffer layer, which absorbs the remaining impact energy again. After the impact, the three-dimensional mesh buffer plate returns to its initial state due to its own elastic material properties, and the gas in the airbag 308 is slowly discharged through the check valve 309. Under the combined action of the restoring force of the micro hydraulic damper and the elastic force of the spring 403, the positioning plate 307 returns to its initial position to prepare for the next possible impact, so as to achieve continuous protection of the battery.
