Description

Technical Field

[0001] This invention relates to the field of hydrogen fuel cell amusement park vehicle technology, specifically to a hydrogen fuel cell amusement park vehicle. Background Technology

[0002] The working principle of a hydrogen fuel cell vehicle is as follows: Hydrogen gas is delivered from a hydrogen cylinder to the anode (negative electrode) of the fuel cell. Through the action of a catalyst (platinum), an electron is separated from a hydrogen atom. The hydrogen ion (proton), having lost its electron, passes through the proton exchange membrane and reaches the cathode (positive electrode). Electrons, however, cannot pass through the proton exchange membrane; they must reach the cathode via an external circuit, thus generating an electric current. Upon reaching the cathode, the proton recombines with oxygen atoms and hydrogen ions to form water. Since the oxygen supplied to the cathode can be obtained from the air, as long as hydrogen is continuously supplied to the anode, air to the cathode, and water (vapor) is promptly removed, electrical energy can be continuously provided.

[0003] To protect the environment and conserve resources, more and more park vehicles are using hydrogen fuel cell vehicles instead of traditional rechargeable battery vehicles in parks and scenic areas.

[0004] Existing hydrogen fuel cell amusement park vehicles are generally fully or semi-open. To facilitate use within scenic areas, these vehicles are typically designed to be lightweight with thin, lightweight panels. The hydrogen cylinders are usually secured to the rear of the vehicle with straps. This makes the rear-mounted hydrogen cylinders susceptible to damage in the event of a collision with an object or other vehicle while the vehicle is in motion or parked. Furthermore, when traveling on bumpy roads, the hydrogen cylinders are prone to impact with the vehicle body due to inertia, leading to further damage. Therefore, a new hydrogen fuel cell amusement park vehicle has been proposed to address these issues. Summary of the Invention

[0005] The purpose of this invention is to provide a hydrogen fuel cell amusement park vehicle to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a hydrogen fuel cell amusement park vehicle, comprising a vehicle body and a hydrogen cylinder, wherein a rear seat box is provided at the rear of the vehicle body, a rectangular groove is provided on the top of the rear seat box, a cover plate is provided on the top of the rectangular groove, and transverse grooves communicating with the rectangular groove are provided on the left and right sides of the rear seat box, an installation plate is provided in the rectangular groove, the hydrogen cylinder is fixed to the top of the installation plate by multiple hoops, a shock absorption device is provided between the installation plate and the bottom wall of the rectangular groove, and a side protection device is provided in the transverse groove, the side protection device including a collision protection component, a triggering mechanism and an airbag mechanism, wherein the collision protection component includes a movable plate, the movable plate being movably disposed in the transverse groove.

[0007] Furthermore, a tail plate is provided at the rear of the rear seat box, and a connecting groove is formed between the rear seat box and the tail plate. Multiple corrugated plates are fixed between the inner walls on both sides of the connecting groove.

[0009] Furthermore, the triggering mechanism includes a reaction chamber, inside which a pressure plate is movably disposed. Multiple connecting rods are fixed to the outside of the pressure plate. The connecting rods are movably inserted into the reaction chamber. A disc-shaped block is fixed to the end of the connecting rod. The central axis of the disc-shaped block coincides with the central axis of the top rod. The outer end face of the disc-shaped block does not contact the end of the top rod.

[0010] Furthermore, the reaction chamber is filled with ammonium nitrate.

[0011] Furthermore, the airbag mechanism includes a second fixing plate, an airbag is fixedly fixed to the inner side of the second fixing plate, a venting pipe is fixedly connected between the top of the airbag and the top of the reaction chamber, and a gas one-way valve is connected between the venting pipes.

[0012] Furthermore, the shock absorption device includes fixed blocks fixed to both sides of the bottom end of the mounting plate, two fixed rods fixed between the fixed blocks, two sets of mounting grooves opened on the bottom wall of the rectangular groove, the two sets of mounting grooves are respectively located on one side of the two fixed rods, a fixed shaft is fixed between the groove walls of the mounting grooves, a slider is movably connected to the shaft of the fixed shaft, a second spring is fixed between the slider and the groove wall of the mounting groove, a connecting shaft is fixed to the top of the slider, a hinge plate is movably connected to the shaft of the connecting shaft, and the other side of the hinge plate is movably connected to the fixed rod.

[0015] This hydrogen fuel cell amusement vehicle is equipped with anti-collision components, a triggering mechanism, and an airbag mechanism on the side of the rear seat. When the side of the rear seat is subjected to a large impact, the anti-collision components trigger the ammonium nitrate in the triggering mechanism to react, thereby generating a large amount of gas. The gas quickly enters the airbag, thus protecting both sides of the hydrogen cylinder and effectively protecting the hydrogen cylinder from damage.

[0016] In addition, a shock absorption device is installed. During the driving process, external vibrations are transmitted upward along the vehicle body.

[0027] To address the issue that the hydrogen tank 7 of existing hydrogen fuel cell amusement park vehicles is easily damaged by impacts or when driving on bumpy roads, such as... Figures 1-4 As shown, the present invention provides a technical solution.

[0028] A hydrogen fuel cell amusement park vehicle includes a vehicle body 1 and a hydrogen cylinder 7. A rear seat box 2 is provided at the rear of the vehicle body 1. A rectangular groove is formed on the top of the rear seat box 2, and a cover plate 12 is provided on the top of the rectangular groove. Transverse grooves connected to the rectangular groove are formed on the left and right sides of the rear seat box 2. An installation plate 8 is provided in the rectangular groove. The hydrogen cylinder 7 is fixed to the top of the installation plate 8 by multiple ties 10. The ties 10 are fixed to the installation plate 8 by bolts, which facilitates the maintenance of the hydrogen cylinder 7 in the future. A shock-absorbing device 9 is provided between the installation plate 8 and the bottom wall of the rectangular groove to buffer the vibration of the amusement park vehicle when it is in motion. A side protection device is provided in the transverse groove. The side protection device includes a collision protection component 4, a triggering mechanism and an airbag mechanism. The collision protection component 4, the triggering mechanism and the airbag mechanism are arranged from left to right. The collision protection component 4 includes a movable plate 401, which is movably arranged in the transverse groove.

[0029] For protection of the back of hydrogen cylinder 7, such as Figure 1 and Figure 3As shown, a tail plate 201 is provided at the rear of the rear seat box 2. The tail plate 201 and the rear seat box 2 can be integrally formed. The tail plate 201 is connected to the top of the rear seat box 2. A connecting groove is formed between the rear seat box 2 and the tail plate 201. Multiple corrugated plates 3 are fixed between the inner walls on both sides of the connecting groove. Since stainless steel plates have a certain toughness and are not easy to rust, in order to improve the aesthetics and safety of the amusement vehicle, the corrugated plates 3 are preferably stainless steel plates.

[0030] When the amusement park vehicle is rear-ended or reverses into an external object, the tailgate 201 bends, causing the corrugated plate 3 to be compressed, which can effectively buffer the impact force and further improve the safety of the hydrogen cylinder 7.

[0031] To ensure the smooth implementation of this plan, such as Figure 1 and Figure 3 As shown, it should be noted that the anti-collision component 4 also includes a first fixed plate 402 fixed to the transverse groove wall. A top rod 403 is fixed at the four corners of the inner side of the movable plate 401, and the top rod 403 is movably inserted into the first fixed plate 402. Four first springs 404 are fixed between the inner side of the movable plate 401 and the first fixed plate 402, and the top rod 403 is located inside the spiral coil of the first spring 404.

[0032] To ensure the smooth implementation of this plan, such as Figure 3 As shown, it is important to understand that the triggering mechanism includes a reaction chamber 501, a pressure plate 502 is movably disposed inside the reaction chamber 501, four connecting rods 503 are fixed on the outside of the pressure plate 502, and the connecting rods 503 are movably inserted into the reaction chamber 501. A disc-shaped block 504 is fixed at the end of the connecting rod 503, the central axis of the disc-shaped block 504 coincides with the central axis of the push rod 403, and the outer end face of the disc-shaped block 504 does not contact the end of the push rod 403.

[0033] It should be noted that in this scheme, the reaction chamber 501 is filled with ammonium nitrate.

[0034] It should be noted that, due to the certain distance between the end of the push rod 403 and the side of the disc block 504, when the external impact is small, the first spring 404 is compressed and deformed to buffer the external force, and the end of the push rod 403 still does not contact the side of the disc block 504. When the external force is large, the first spring 404 is compressed and deformed, and the push rod 403 moves to the right. The push rod 403 quickly pushes the disc block 504 to the right. At this time, the pressure plate 502 compresses (at a relatively high speed, equivalent to a collision) the ammonium nitrate filled in the reaction chamber 501, and the ammonium nitrate reacts to form a large amount of gas. The reaction equation is as follows:

[0035] To achieve protection on both sides of hydrogen cylinder 7, such as Figure 3As shown, the airbag mechanism includes a second fixing plate 601, an airbag 602 is fixed on the inner side of the second fixing plate 601, a vent pipe 603 is fixedly connected between the top of the airbag 602 and the top of the reaction chamber 501, and a gas one-way valve 604 is connected between the vent pipes 603.

[0036] The nitrogen and oxygen produced by the reaction enter the gas bag 602 through the gas one-way valve 604, thereby inflating the gas bag 602 and achieving protection for both sides of the hydrogen cylinder 7.

[0037] To effectively cushion the vibrations caused by bumps between the wheels and the ground while the amusement park vehicle is in motion, and to reduce the damage to the hydrogen cylinder 7 caused by vibrations, such as... Figure 3 and Figure 4 As shown, the shock absorption device 9 includes fixed blocks fixed to both sides of the bottom end of the mounting plate 8. Two fixed rods 901 are fixed between the fixed blocks. Two sets of mounting grooves 902 are opened on the bottom wall of the rectangular groove, and the two sets of mounting grooves 902 are respectively located on one side of the two fixed rods 901. A fixed shaft is fixed between the groove walls of the mounting grooves 902. A slider 903 is movably connected to the shaft of the fixed shaft. A second spring 904 is fixed between the slider 903 and the groove wall of the mounting groove 902. A connecting shaft is fixed to the top of the slider 903. A hinge plate 905 is movably connected to the shaft of the connecting shaft, and the other side of the hinge plate 905 is movably connected to the fixed rod 901.

[0038] External vibrations are transmitted upwards along the vehicle body, and hydrogen cylinder 7 moves downwards due to inertia. At this time, the second spring 904 is pulled. Finally, under the elastic action of the second spring 904 and the cooperation of the slider 903 and the hinge plate 905, the external vibrations can be effectively buffered, reducing the damage to hydrogen cylinder 7 caused by external vibrations.

[0039] To further improve the stability of the hydrogen cylinder 7 installation, in this design, guide shafts 11 are fixed at the four corners of the bottom wall of the rectangular groove, and the guide shafts 11 are movably connected to the mounting plate 8.

[0040] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
