Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of hydrogen transport vehicles, and in particular relates to an anti-rollover fixing structure for a hydrogen transport vehicle. Background Art
[0002] A hydrogen transport vehicle is a special vehicle designed for the safe transportation of compressed hydrogen or liquid hydrogen. Most hydrogen transport vehicles are composed of two major parts: a tank body and a chassis. Hydrogen transport vehicles are very prone to rollover under certain external forces when loading or moving. Therefore, a special anti-rollover fixed structure for hydrogen transport vehicles is required.
[0003] The existing anti-rollover fixed structure of hydrogen transport vehicles is usually equipped with retractable cylinders and support seats connected to them on both sides of the frame of the hydrogen transport vehicle. When parking or loading and unloading, the cylinders work to make the support seats contact the ground, forming a stable support point to prevent the vehicle from rolling over due to uneven force in a static state. However, during the driving of the vehicle, this fixed anti-rollover device cannot provide continuous dynamic stability support and still has certain limitations when used. Utility Model Content
[0004] In view of this, the utility model provides a hydrogen transport vehicle anti-rollover fixing structure, which can realize the intelligent sensing, response and regulation functions of the anti-rollover system through the anti-rollover mechanism, and can provide continuous dynamic stability support for the hydrogen transport vehicle during movement, ensuring that the hydrogen transport vehicle can always maintain the anti-rollover effect when moving, preventing the anti-rollover effect from being weakened due to the forces in the front and rear directions, ensuring that the support legs and support wheels can return to their positions smoothly when not in use, and maintain a stable storage state, thereby reducing unnecessary vibrations during vehicle driving.
[0005] In order to solve the above technical problems, the utility model provides an anti-rollover fixing structure for a hydrogen transport vehicle, including a mounting frame and an anti-rollover mechanism arranged in the middle of the lower end of the mounting frame, the anti-rollover mechanism includes a rotating seat rotatably connected to the middle of the lower surface of the mounting frame, the inner cavity of the rotating seat is rotatably connected to a support leg, the lower end of the right surface of the support leg is rotatably connected to a support wheel, a limit block is provided in the middle of the right end of the mounting frame, a limit groove matched with the support leg is provided in the middle of the lower surface of the limit block, an elastic support assembly is also provided between the rotating seat and the support leg, and a driving assembly for driving the rotating seat to move is also provided at the front end of the mounting frame.
[0006] The top wall surface of the limiting groove is arranged to be inclined upward from left to right.
[0007] The elastic support assembly includes a fixed plate longitudinally symmetrically arranged at the upper ends of the front and rear surfaces of the support leg, a longitudinally symmetrically distributed fixed block is arranged at the lower ends of the front and rear surfaces of the rotating seat, and a transversely symmetrically distributed spring is arranged between the upper surface of the fixed block and the left side of the lower surface of the adjacent fixed plate on the same side.
[0008] The driving assembly includes an electric push rod rotatably connected to the middle part of the front end of the upper and lower walls of the mounting frame, a transmission plate is provided on the upper side of the left rear end of the rotating seat, a rotating rod is rotatably connected to the left side of the upper surface of the transmission plate, and the upper end of the outer arc surface of the rotating rod is fixedly connected to the rear end of the telescopic end of the electric push rod.
[0009] A level sensor is arranged in the middle of the upper surface of the mounting frame.
[0010] The electric push rod and the level sensor are both electrically connected to the built-in microcontroller of the hydrogen transport vehicle.
[0011] The left and right sides of the upper surface of the mounting frame are provided with mounting holes evenly distributed in the longitudinal direction.
[0012] The beneficial effects of the above technical solution of the utility model are as follows:
[0013] 1. The horizontal sensor monitors the posture of the vehicle in real time and accurately captures any possible roll tendency or actual roll angle change. When the horizontal sensor detects that the vehicle deviates from the horizontal reference and exceeds the preset safety threshold, it will immediately send an alarm signal to the built-in single-chip microcomputer of the hydrogen transport vehicle. After receiving the signal, the built-in single-chip microcomputer of the hydrogen transport vehicle will immediately adjust the operation of the electric push rod to make its telescopic end move again, thereby starting the deployment process of the anti-rollover device. Conversely, when the vehicle returns to its normal posture or the anti-rollover device needs to be retracted, the intelligent sensing, response and control functions of the anti-rollover system are realized, which can provide continuous dynamic stability support for the hydrogen transport vehicle during movement, ensuring that the hydrogen transport vehicle can always maintain the anti-rollover effect when moving.
[0014] 2. When the vehicle is parking, loading hydrogen, etc., the built-in single-chip microcomputer of the hydrogen transport vehicle controls the operation of the electric push rod. The telescopic end of the electric push rod extends and rotates through the rotating rod and the transmission plate to link the rotating seat, so that the support legs, support wheels, fixed plates, fixed blocks and springs are expanded outward, so that the support wheels contact the ground, providing additional stable support points for the hydrogen transport vehicle, effectively preventing the vehicle from rolling over. Once the vehicle tilts, the support legs and support wheels will be embedded in the limit grooves under the action of force to ensure that the position of the support components is locked and limited, preventing the anti-rollover effect from being weakened due to the forces in the front and rear directions.
[0015] 3. The spring, relying on its own elastic characteristics, provides the necessary reset driving force when there is no external force, ensuring that the support legs and support wheels can return to their original positions smoothly when not in use, and maintain a stable storage state, thereby reducing unnecessary vibrations during vehicle driving.

Based on the described embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.
[0022] like Figure 1-4 As shown:
[0023] The present embodiment provides an anti-rollover fixing structure for a hydrogen transport vehicle, including a mounting frame 100 and an anti-rollover mechanism arranged in the middle of the lower end of the mounting frame 100, the anti-rollover mechanism including a rotating seat 200 rotatably connected to the middle of the lower surface of the mounting frame 100, the inner cavity of the rotating seat 200 is rotatably connected to a support leg 201, the lower end of the right surface of the support leg 201 is rotatably connected to a support wheel 202, a limit block 203 is provided in the middle of the right end of the mounting frame 100, a limit groove 204 matched with the support leg 201 is provided in the middle of the lower surface of the limit block 203, an elastic support component is also provided between the rotating seat 200 and the support leg 201, and a driving component for driving the rotating seat 200 to move is also provided at the front end of the mounting frame 100.
[0024] like Figure 1-4 As shown, the elastic support assembly includes a fixed plate 300 longitudinally symmetrically arranged at the upper ends of the front and rear surfaces of the support leg 201, a longitudinally symmetrically distributed fixed block 301 is provided at the lower ends of the front and rear surfaces of the rotating seat 200, and a transversely symmetrically distributed spring 302 is provided between the upper surface of the fixed block 301 and the left side of the lower surface of the adjacent fixed plate 300 on the same side.
[0025] like Figure 1-4As shown, the driving assembly includes an electric push rod 400 rotatably connected to the middle of the front end of the upper and lower walls of the mounting frame 100, a transmission plate 401 is provided on the upper side of the left rear end of the rotating seat 200, and a rotating rod 402 is rotatably connected to the left side of the upper surface of the transmission plate 401, and the upper end of the outer arc surface of the rotating rod 402 is fixedly connected to the rear end of the telescopic end of the electric push rod 400.
[0026] like Figure 1-4 As shown, a level sensor 500 is provided in the middle of the upper surface of the mounting frame 100 .
[0027] like Figure 1-4 As shown, the electric push rod 400 and the level sensor 500 are both electrically connected to the built-in single chip microcomputer of the hydrogen transport vehicle.
[0028] like Figure 1-4 As shown, both left and right sides of the upper surface of the mounting frame 100 are provided with mounting holes 600 evenly distributed in the longitudinal direction.
[0029] The working principle of the anti-rollover fixing structure of the hydrogen transport vehicle provided by the utility model is as follows: when the vehicle is parking, loading hydrogen, etc., the built-in single-chip computer of the hydrogen transport vehicle controls the operation of the electric push rod 400, and the telescopic end of the electric push rod 400 extends and simultaneously rotates the rotating seat 200 through the rotating rod 402 and the transmission plate 401, thereby making the support leg 201, the support wheel 202, the fixing plate 300, the fixing block 301 and the spring 302 expand outward, so that the support wheel 202 contacts the ground, providing additional stability for the hydrogen transport vehicle. The support point can effectively prevent the vehicle from rolling over. Once the vehicle tilts, the support leg 201 and the support wheel 202 will be embedded in the limit groove 204 under the action of force, ensuring that the position of the support component is locked and limited, preventing the front and rear forces from weakening the anti-rollover effect. Among them, the spring 302 provides the necessary reset driving force when there is no external force, ensuring that the support leg and the support wheel can return to their original position smoothly when not in use, and maintain a stable storage state, reducing unnecessary vibration during vehicle driving. In addition, the horizontal sensor The device 500 monitors the posture of the vehicle in real time, accurately captures any possible roll tendency or actual roll angle change. When the horizontal sensor detects that the vehicle deviates from the horizontal reference and exceeds the preset safety threshold, it will immediately send an alarm signal to the built-in single-chip microcomputer of the hydrogen transport vehicle. After receiving the signal, the built-in single-chip microcomputer of the hydrogen transport vehicle will immediately adjust the operation of the electric push rod 400 to make its telescopic end move again, thereby starting the deployment process of the anti-rollover device. Conversely, when the vehicle returns to a normal posture or the anti-rollover device needs to be retracted, the intelligent sensing, response and regulation functions of the anti-rollover system are realized, which can provide continuous dynamic and stable support for the hydrogen transport vehicle during movement, ensuring that the hydrogen transport vehicle can always maintain the anti-rollover effect when moving. The entire anti-rollover fixed structure is firmly installed on the chassis of the hydrogen transport vehicle by professionals through the mounting hole 600, ensuring that a stable and reliable mechanical connection is formed between the anti-rollover system and the vehicle body, effectively ensuring the effective transmission of the supporting force and the ability to bear the load, and fundamentally improving the safety and stability of the hydrogen transport vehicle during operation.
[0030] like Figure 1-3 As shown, the top wall surface of the limiting groove 204 is tilted upward from left to right, so that the support leg 201 is more tightly in contact with the limiting groove 204, thereby increasing the locking and limiting performance of the structure.
[0031] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.
[0032] The above is a preferred embodiment of the present invention.

These improvements and modifications should also be regarded as the protection scope of the present invention.
