Technical Field

[0001] This invention relates to the field of battery liquid hydrogen system technology, and more particularly to a fuel cell liquid hydrogen system. Background Technology

[0002] A fuel cell liquid hydrogen system is a technology that uses the reaction of hydrogen and oxygen to generate electricity. This system typically includes a fuel cell stack, a hydrogen supply system, an oxygen supply system, a cooling system, a control system, and an electrical system.

[0003] However, there is a safety issue with the current fuel cell liquid hydrogen system after connecting the related system parts. Generally, the fuel cell liquid hydrogen system is installed in the car, and it is directly exposed. When the car drives over bumpy roads, if there are other loose parts or other parts in the car that have fallen off after long-term use, they may hit the fuel cell liquid hydrogen system after the bumps, causing accidental damage.

[0004] To address the aforementioned issues, we propose a fuel cell liquid hydrogen system. Summary of the Invention

[0005] The purpose of this invention is to solve the problems in the background art by proposing a fuel cell liquid hydrogen system.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a fuel cell liquid hydrogen system, including a fixed base, a liquid hydrogen body for the battery located at the middle portion of the fixed base, a crash plate fixedly installed on the top of the fixed base, a sliding opening on the top of the crash plate, a telescopic plate slidably inserted into the sliding opening, a support plate fixedly connected to the top of the fixed base, a motor fixedly connected to the outer wall of the support plate, a gear fixedly installed at the middle portion of the drive end of the motor, a pulley fixedly connected to the end of the drive end of the motor, and a transmission mechanism symmetrically arranged on the left and right sides of the motor located on the outer wall of the support plate. The mechanism includes a rotating rod 1, which is rotatably connected to the left and right sides of the outer wall of the support plate. A gear 2 is fixedly connected to the middle part of the rotating rod 1. The inner wall of the telescopic plate is provided with a meshing slot, and the gear 2 meshes with the meshing slot. A pulley 2 is fixedly connected to the end of the rotating rod 1. The pulley 1 is connected to the pulley 2 via a belt 1. A rotating rod 2 located on the left side of the motor is fixedly connected to the outer wall of the support plate. A gear 3 is fixedly provided to the middle part of the rotating rod 2. The gear 3 meshes with the gear 1. A pulley 3 is fixedly connected to the end of the rotating rod 2. The pulley 3 is connected to the pulley 2 on the left side via a belt 2.

[0007] In the aforementioned fuel cell liquid hydrogen system, the top of the mounting base has an opening, and the mounting base has a cavity that communicates with the opening. Two fixed cylinders are fixedly connected to the inner wall of the cavity, and a telescopic cylinder is slidably connected to the inner wall of the two fixed cylinders. A movable plate extending out of the mounting base through the opening is fixedly connected to the top of the telescopic cylinder. The liquid hydrogen body of the battery is placed on the surface of the movable plate. A spring is fixedly connected to the inner wall of the cavity, and the top of the spring is fixedly connected to the bottom of the movable plate. A baffle is fixedly connected to the left side of the top of the movable plate.

[0008] In the aforementioned fuel cell liquid hydrogen system, the top of the mounting base is provided with multiple threaded locking holes, and a limiting plate located on the right side of the movable plate is fixedly connected to the top of the mounting base. The limiting plate is provided with two threaded holes and two bolts passing through the threaded holes. A push plate with threads sleeved on the outside of the bolts is provided on the left side of the limiting plate. A fixing block is fixedly connected to the right side wall of the two bolts, and a long rod screw is threadedly connected to the fixing block.

[0010] In the aforementioned fuel cell liquid hydrogen system, the contact portion between the telescopic cylinder and the fixed cylinder is provided with damping fluid, and the two fixed cylinders are located on the left and right sides of the spring.

[0011] In the aforementioned fuel cell liquid hydrogen system, multiple threaded locking holes are located on the right side of the movable plate, the diameter of the long rod screw is equal to the diameter of the multiple threaded locking holes, and the fixing block is located directly above the multiple threaded locking holes.

[0012] In one of the aforementioned fuel cell liquid hydrogen systems, the lengths of the limiting plate and the pushing plate are greater than the width of the liquid hydrogen body.

[0013] Compared with existing technologies, the advantages of this fuel cell liquid hydrogen system are: The motor causes gear one and pulley one to rotate counterclockwise, which in turn drives the rotating rod one to rotate. At the same time, gear two will also rotate and drive the telescopic plate to move vertically upward along the anti-collision plate. When gear one rotates counterclockwise, it will drive gear three to rotate clockwise and drive pulley two of the transmission mechanism on the other side to rotate, thereby extending the anti-collision range of the anti-collision plate and improving the safety of the liquid hydrogen battery body. The liquid hydrogen battery body is placed on the surface of the movable plate. By making the push plate contact the liquid hydrogen battery body, and when the bolt can no longer be turned, the long rod screw is connected to the corresponding threaded buckle through the fixing block, thereby fixing the entire fixture. When the car bumps, it can effectively stabilize the liquid hydrogen battery body, improving its practicality. Attached Figure Description

[0016] The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0017] Reference Figures 1-4A fuel cell liquid hydrogen system includes a mounting base 1, with a liquid hydrogen fuel cell body 6 located in the middle of the mounting base 1. Liquid hydrogen fuel cell refers to a battery system that uses liquid hydrogen as fuel. Liquid hydrogen is a storage form of hydrogen gas, typically in a liquid state at extremely low temperatures (approximately -253 degrees Celsius). Its advantages include: high energy density, making it a potentially high-efficiency energy source; zero emissions, as the only emission from a fuel cell using liquid hydrogen is water vapor, producing no pollutants; and rapid refueling, as refueling with liquid hydrogen can be faster than charging a battery, thus reducing charging time. A crash barrier 2 is fixedly installed on the top of the mounting base 1, and a sliding opening is provided on the top of the crash barrier 2. A telescopic plate 3 is slidably inserted into the sliding opening. A support plate 23 is fixedly connected to the top of the mounting base 1. A motor 13 is fixedly connected to the side wall. A gear 14 is fixedly installed at the middle of the drive end of the motor 13. A pulley 15 is fixedly connected to the end of the drive end of the motor 13. A transmission mechanism is provided on the outer side wall of the support plate 23, symmetrically arranged on the left and right sides of the motor 13. The transmission mechanism includes a rotating rod 18, which is rotatably connected to the left and right sides of the outer side wall of the support plate 23. A gear 17 is fixedly connected at the middle of the rotating rod 18. A meshing joint is provided on the inner side wall of the telescopic plate 3, and the gear 17 meshes with the meshing joint. A pulley 19 is fixedly connected to the end of the rotating rod 1. The pulley 15 is connected to the pulley 19 via a belt 16. Connected to the outer wall of the support plate 23, a rotating rod 20 located to the left of the motor 13 is fixedly connected. A gear 3 21 is fixedly installed at the middle part of the rotating rod 20, and the gear 3 21 meshes with the gear 1 14. A pulley 3 22 is fixedly connected to the end of the rotating rod 20, and the pulley 3 22 is connected to the pulley 2 19 on the left side through a belt 2 24. The anti-collision plate 2 is located at the edge of the fixed seat 1, and the support plate 23 is located behind the anti-collision plate 2. The height of the telescopic plate 3 is greater than the height of the support plate 23, so that the meshing can mesh with the gear 2 17 through the anti-collision plate 2. First, the fixed seat 1 is installed on the car, and then the motor 13 drives the gear 27 to mesh. Wheel 14 and pulley 15 rotate counterclockwise. When pulley 15 rotates, it drives pulley 19 to rotate via belt 16, which in turn drives rotating rod 18 to rotate. At the same time, gear 17 also rotates and drives telescopic plate 3 to move vertically upward along anti-collision plate 2. When motor 13 causes gear 14 to rotate counterclockwise, it drives gear 21 to rotate clockwise, which in turn drives rotating rod 20 and pulley 22 to rotate. When pulley 22 rotates, it drives pulley 19 of the transmission mechanism on the other side to rotate via belt 24, thereby extending the anti-collision range of anti-collision plate 2 and improving the safety of battery liquid hydrogen body 6.

[0018] The top of the fixed base 1 has an opening, and the fixed base 1 has a cavity that communicates with the opening. Two fixed cylinders 26 are fixedly connected to the inner wall of the cavity. Telescopic cylinders 27 are slidably connected to the inner walls of the two fixed cylinders 26. A movable plate 4 extending out of the fixed base 1 through the opening is fixedly connected to the top of the telescopic cylinder. The battery liquid hydrogen body 6 is placed on the surface of the movable plate 4. A spring 25 is fixedly connected to the inner wall of the cavity. The top of the spring 25 is fixedly connected to the bottom of the movable plate 4. A baffle 5 is fixedly connected to the left side of the top of the movable plate 4. Damping fluid is provided at the contact part between the telescopic cylinder 27 and the fixed cylinder 26. The two fixed cylinders 26 are located at... On the left and right sides of the spring 25, when the car passes through a bumpy road section, if the bump is too large, the battery liquid hydrogen body 6 will shake, causing the movable plate 4 to shake downwards. The spring 25 can effectively absorb and buffer most of the shaking impact. The fixed cylinder 26 and the telescopic cylinder 27 can ensure that when shaking occurs, the movable plate 4 will only shake vertically and will not shake from the side, thereby reducing the adverse effects caused by the shaking of the battery liquid hydrogen body 6. By adding damping fluid into the fixed cylinder 26 and the telescopic cylinder 27, the self-shaking generated by the spring 25 during buffering can be effectively reduced, and the effect time of the spring 25 can be accelerated.

[0019] The top of the fixed base 1 is provided with multiple threaded locking holes 9. A limiting plate 7 located on the right side of the movable plate 4 is fixedly connected to the top of the fixed base 1. The limiting plate 7 is provided with two threaded holes and two bolts 8 passing through the threaded holes. A push plate 12 with threads sleeved on the outside of the bolts 8 is provided on the left side of the limiting plate 7. A fixing block 10 is fixedly connected to the right side wall of the two bolts 8. A long rod screw 11 is internally threaded to the fixing block 10. Multiple threaded locking holes 9 are located on the right side of the movable plate 4. The diameter of the long rod screw 11 is equal to the diameter of the multiple threaded locking holes 9. The fixing block 10 is located directly above the multiple threaded locking holes 9. The limiting plate 7 and the push plate The length of the push plate 12 is greater than the width of the liquid hydrogen battery body 6. The liquid hydrogen battery body 6 is placed on the surface of the movable plate 4 and makes the liquid hydrogen battery body 6 contact the baffle 5. When the liquid hydrogen battery body 6 moves downward due to gravity, it will exert pressure on the movable plate 4. When it is stable, the push plate 12 is moved vertically to the left along the bolt plate 8 by rotating the bolt 8. When the push plate 12 contacts the liquid hydrogen battery body 6 and the bolt 8 can no longer be turned, the long rod screw 11 is connected to the corresponding threaded locking hole 9 through the fixing block 10, thereby fixing the entire clamp. When the car bumps, it can effectively stabilize the liquid hydrogen battery body 6, improving its practicality.

[0020] The working principle of this invention is as follows: Motor 13 causes gear 14 and pulley 15 to rotate counterclockwise. When pulley 15 rotates, it drives pulley 19 to rotate via belt 16, which in turn drives rotating rod 18 to rotate. At the same time, gear 17 also rotates and drives telescopic plate 3 to move vertically upward along anti-collision plate 2. When motor 13 causes gear 14 to rotate counterclockwise, it drives gear 21 to rotate clockwise, which in turn drives rotating rod 20 and pulley 22 to rotate. When pulley 22 rotates, it drives pulley 19 of the transmission mechanism on the other side to rotate via belt 24. This can speed up the movement of telescopic plate 3 and improve the stability of vertical upward movement, thereby extending the anti-collision range of anti-collision plate 2 and improving the safety of battery liquid hydrogen body 6. Next, by placing the liquid hydrogen battery body 6 on the surface of the movable plate 4 and making the liquid hydrogen battery body 6 contact the baffle 5, the liquid hydrogen battery body 6 will exert pressure on the movable plate 4 due to gravity and move downward. When it is stable, the push plate 12 is moved vertically to the left along the bolt plate 8 by rotating the bolt 8. When the push plate 12 contacts the liquid hydrogen battery body 6 and the bolt 8 can no longer be turned, the long rod screw 11 is connected to the corresponding threaded locking hole 9 through the fixing block 10, thereby fixing the entire clamp. When the car bumps, it can effectively stabilize the liquid hydrogen battery body 6, improving its practicality.
