Description

Technical Field

[0001] This utility model relates to the field of battery protection technology, and in particular to an anti-bump device for a truck starting and parking battery. Background Technology

[0002] As a core component of the electrical system, the truck starter battery bears the important mission of starting the engine, powering the vehicle's electrical appliances, and maintaining the system's power supply when the generator stops. When the truck is driving on complex road conditions, continuous bumps and vibrations become the main threat to the starter battery. Without effective shock absorption measures, the battery is prone to problems such as plate breakage, shell cracking, or electrode loosening, which will not only significantly shorten the battery's lifespan but also directly affect the vehicle's starting performance.

[0003] Currently, dampers and airbags are commonly used in automotive shock absorption to protect the car's battery and prevent vibration from damaging it. Airbags are mostly made of polymer materials such as rubber and TPU (thermoplastic polyurethane). Although these materials have a certain degree of sealing, there are still microscopic gaps between molecules. Gas molecules can slowly permeate from the high-pressure side (inside the airbag) to the low-pressure side (outside) through "diffusion," which reduces the shock absorption effect of the airbag. Therefore, it is necessary to replenish the airbag with gas in a timely manner during the use of airbag shock absorption. Existing devices can use a pressure detection device in conjunction with an air pump and a controller to automatically replenish the airbag. However, these devices are expensive and require a portable power source. When the power is off, the air pump cannot start, the pressure detection device loses its data acquisition capability, and the airbag pressure continues to decrease due to the continuous diffusion of gas molecules, resulting in weakened airbag elasticity or even complete collapse. This makes it unable to absorb the vibration generated by road bumps, thus damaging the battery.

[0004] Therefore, it is necessary to invent an anti-bump device for starting the parking battery of a truck to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an anti-bump device for starting and parking batteries in trucks, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an anti-bump device for a truck starting and parking battery, comprising a base, a fixing block symmetrically fixedly installed on the top of the base, crossbars symmetrically fixedly connected to both ends of the fixing block, a connecting plate movably passing through the two crossbars, a first compression spring sleeved on the outer circumferential surface of the crossbars with its two ends respectively abutting against the fixing block and the connecting plate, a side plate fixedly connected to the other end of the connecting plate, a plurality of limiting rods symmetrically movably passing through both ends of the outer surface of the side plate, a compression plate fixedly connected to the ends of the plurality of limiting rods, an airbag disposed between the compression plate and the side plate, a battery box fixedly installed inside the airbag, a base plate disposed at the bottom of the battery box, an inflation assembly for inflating the airbag disposed on the top of the base, the inflation assembly including a counterweight block slidably connected to the inner side of the fixing block, an air cylinder disposed below one side of the counterweight block, a fixing plate sleeved on the outer circumferential surface of the air cylinder, and a positioning block for fixing the air cylinder fixedly installed on one side of the fixing plate.

[0007] Preferably, a groove is provided in the middle of the upper part of the inner side of the fixing block to slide and connect with the counterweight block, and a horizontal plate is fixedly installed on the top of the groove.

[0008] Preferably, an air storage chamber is fixedly installed on the top of the base near the fixing block, a one-way valve is fixedly installed on one side of the air storage chamber, the end of the one-way valve is fixedly connected to the air injection head of the air cylinder, an air nozzle is opened on the top of the air storage chamber, and hoses are installed on the top and side of the air storage chamber, with the end of the hoses connected to the air injection hole of the air bag.

[0009] Preferably, a vertical plate is fixedly installed on the top of the gas storage chamber above the gas nozzle. A limit hole is opened on one side of the vertical plate. A vertical rod is movably inserted through the middle of the top of the vertical plate. A ring is fixedly connected to the bottom end of the vertical rod. A sealing head for insertion into the gas nozzle is fixedly connected to the bottom end of the ring.

[0010] Preferably, the end of the vertical plate is threadedly connected to a threaded rod, the bottom end of the threaded rod is rotatably connected to a connecting block, the connecting block is slidably connected to a limiting hole, the end of the connecting block is fixedly connected to a limiting plate that movably passes through the vertical rod, and the outer circumferential surface of the vertical rod is fitted with a second compression spring at both ends for abutting against the limiting plate and the ring respectively.

[0011] Preferably, shock absorbers are fixedly installed at the four top corners of the base, and the two ends of the shock absorbers are fixedly connected to the four bottom corners of the base plate and the four top corners of the base, respectively. L-shaped support plates are symmetrically fixedly connected to the two bottom ends of the base plate, and the L-shaped support plates are movably connected through a limiting post whose bottom end is fixedly connected to the top of the base.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. The counterweight moves up and down in the chute, which drives the air cylinder to automatically replenish the air chamber. The air is then continuously supplied to the airbag through the pipeline. It does not require electric drive, which avoids the risk of air replenishment failure when the power is off and reduces costs. The mechanical air replenishment component, which consists of the air cylinder and the one-way valve, uses the kinetic energy of vehicle bumps to convert into air pressure energy, ensuring that the airbag pressure is always maintained in the effective shock absorption range and avoiding the reduction of shock absorption effect due to gas diffusion.

[0014] 2. Through the mechanical cooperation between the conical air nozzle and the sealing head, the sealing head is automatically opened to release air when the air pressure is too high. The exhaust threshold can be manually adjusted by rotating the threaded rod. No electronic components are required, which eliminates the failure of air replenishment due to circuit failure or sensor malfunction. At the same time, it eliminates the need for maintenance steps such as sensor calibration and circuit repair, reducing maintenance costs. Attached Figure Description

[0021] 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.

[0022] This utility model provides, for example Figures 1-4 The illustrated anti-bump device for a truck starting and parking battery includes a base 1. A fixing block 3 is symmetrically fixedly mounted on the top of the base 1. Crossbars 4 are symmetrically fixedly connected to both ends of the fixing blocks 3. A connecting plate 6 movably passes through the two crossbars 4. A first compression spring 5 is sleeved on the outer surface of the crossbars 4, with its two ends respectively abutting against the fixing blocks 3 and the connecting plate 6. A side plate 7 is fixedly connected to the other end of the connecting plate 6. Multiple limiting rods 8 symmetrically and movably pass through both ends of the outer surface of the side plate 7. A compression plate 9 is fixedly connected to the ends of the multiple limiting rods 8. An airbag 10 is disposed between the compression plate 9 and the side plate 7. A battery box 11 is fixedly mounted inside the airbag 10. A base plate 12 is disposed at the bottom of the battery box 11. An inflation assembly for inflating the airbag 10 is disposed on the top of the base 1. The inflation assembly includes a counterweight 13 that is slidably connected to the inner side of the fixing block 3. An air cylinder 14 is provided below one side of the counterweight 13. A fixing plate 15 is sleeved on the outer peripheral surface of the air cylinder 14. A positioning block 16 for fixing the air cylinder 14 is fixedly installed on one side of the fixing plate 15. When the truck is driving on a bumpy road, the starting battery installed on the truck will generate irregular vibrations. When the battery box 11 sways left and right due to the vibration, the airbag 10 located between the side plate 7 and the compression plate 9 is squeezed by the impact force. The internal gas is compressed and the volume is reduced. During the gas compression process, the kinetic energy generated by the vibration is converted into the internal energy of the gas, thereby reducing the transmission of vibration to the protected object. After the impact force disappears, the compressed gas expands and returns to its original state, pushing the airbag 10 to reset.

[0023] A groove 301 is provided in the middle of the upper part of the inner side of the fixed block 3, which is slidably connected to the counterweight block 13. A horizontal plate 302 is fixedly installed on the top of the groove 301. An air storage chamber 18 is fixedly installed on the top of the base 1 near the fixed block 3. A one-way valve 17 is fixedly installed on one side of the air storage chamber 18. The end of the one-way valve 17 is fixedly connected to the air injection head of the air cylinder 14. An air nozzle 1801 is provided on the top of the air storage chamber 18. A hose is installed on the top and side of the air storage chamber 18. The end of the hose is connected to the air injection hole of the airbag 10. At the same time, when the truck is driving on a bumpy road, the fixed block The counterweight 13 between the three will swing irregularly with the bumps of the truck. Due to the limiting effect of the slide 301, the potential energy generated by the counterweight 13 will cause the counterweight 13 to move up and down in the slide 301, thereby driving the pressing part of the air cylinder 14 to move up and down, thereby generating gas, which is delivered to the air storage chamber 18 through the one-way valve 17. The one-way valve 17 can prevent the gas from flowing back and causing the gas to overflow. Since the air storage chamber 18 and the air bag 10 are connected by a pipe, the air pressure of the air storage chamber 18 can be delivered to the air bag 10, thereby achieving the function of automatic inflation.

[0024] A vertical plate 19 is fixedly installed on the top of the gas storage chamber 18 above the gas nozzle 1801. A limit hole 1901 is opened on one side of the vertical plate 19. A vertical rod 20 is movably passed through the middle of the top of the vertical plate 19. A ring 24 is fixedly connected to the bottom end of the vertical rod 20. A sealing head 26 for insertion into the gas nozzle 1801 is fixedly connected to the bottom end of the ring 24. A threaded rod 21 is threadedly connected to the end of the vertical plate 19. A connecting block 22 is rotatably connected to the bottom end of the threaded rod 21. The connecting block 22 is slidably connected to the limit hole 1901. A limit plate 23 that movably passes through the vertical rod 20 is fixedly connected to the end of the connecting block 22. A second compression spring 25 is sleeved on the outer circumferential surface of the vertical rod 20, with its two ends respectively abutting against the limit plate 23 and the ring 24. Shock absorbers 2 are fixedly installed at the four corners of the top of the base 1. The two ends of the shock absorbers 2 are fixedly connected to the four corners of the bottom of the base plate 12 and the four corners of the top of the base 1, respectively. The device has L-shaped support plates 102 fixedly connected symmetrically at both ends. The L-shaped support plates 102 are movably connected through a limiting post 101 fixedly connected to the base 1 at the bottom. The movable connection between the L-shaped support plates 102 and the limiting post 101 can improve the stability of the device. The air nozzle 1801 at the top of the air storage chamber 18 is conical and has a small diameter. When the air pressure in the air storage chamber 18 and the air bag 10 is sufficient, the air pressure generated by the air cylinder 14 continues to be delivered to the air storage chamber 18. The excess air pressure will push up the sealing head 26, thereby compressing the second compression spring 25 and relieving the excess air pressure inside. At the same time, by rotating the threaded rod 21, the connecting block 22 at the bottom can be moved downward, thereby causing the limiting plate 23 to squeeze the second compression spring 25, thereby changing the pressure between the sealing head 26 and the air nozzle 1801, thereby changing the critical value of gas overflow in the air storage chamber 18 and achieving the function of regulation.

[0025] It should be noted that when the battery box 11 is squeezed against the airbag 10, the increased internal air pressure of the airbag 10 will push up the sealing head 26. However, due to the size of the air nozzle 1801, the speed of gas leakage will be slowed down. When the battery box 11 is reset, the airbag 10 will also be reset. Furthermore, the air pressure in the airbag 10 and the air storage chamber 18 will be quickly replenished by the gas generated by the air cylinder 14, thereby keeping the air pressure of the airbag 10 within a suitable range and improving the vibration damping stability of the airbag 10.

[0026] The working principle of this utility model is as follows: When the truck is traveling on a bumpy road, the battery box 11 sways left and right, squeezing the airbag 10 between the side plate 7 and the compression plate 9. The gas inside the airbag 10 is compressed, converting the vibration kinetic energy into internal energy, reducing vibration transmission. After the impact force disappears, the gas expands and pushes the airbag 10 back to its original position. At the same time, when the truck is bumping, the counterweight 13 between the fixed blocks 3 moves up and down in the restricted position within the slide groove 301, driving the pressing part of the air cylinder 14 to move and generate gas, which is sent into the air storage chamber 18 through the one-way valve 17. Air is supplied to the airbag 10 through the pipeline. The air nozzle 1801 at the top of the air storage chamber 18 is conical. When the internal air pressure is too high, the excess air pressure pushes up the sealing head 26 and compresses the second compression spring 25 to exhaust the air. Finally, the pressure of the sealing head 26 and the air nozzle 1801 can be adjusted by rotating the threaded rod 21 to change the critical value of gas overflow in the air storage chamber 18. The shock absorbers 2 at the four corners of the base 1 consume vibration energy by generating resistance through the flow of liquid in the cylinder. They work together with the airbag 10 to reduce vibration and ensure the stability of the battery box 11 when it is bumpy.

[0027] It should be noted that the sealing head 26 and the air nozzle 1801 in this embodiment are both tapered designs, used only to provide a sealing effect. Their shapes include, but are not limited to, those shown in the drawings, and can be selected according to the actual needs of the device. Furthermore, the diameters of the sealing head 26 and the air nozzle 1801 in this embodiment are not limited.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
