[0022] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.
[0023] Please see Figures 1 to 4This application provides a reversing tricycle. The reversing tricycle uses a certain amount of electrical wires, signal transmission lines, water pipes, oil pipes, etc., for the reclining frame 2 to rotate, all of which can pass through the base frame 1. It includes the base frame 1 and the reclining frame 2. In addition to the parts shown in the figure, the reclining frame 2 also has protective frames for the head and sides of the body. The driver can enter from the top, similar to the entry method of an F1 race car. A rear wheel 3 and two front wheels 4 are rotatably mounted on the base frame 1. A drive motor is mounted on the rear wheel 3, driving the rear wheel 3 to rotate, equivalent to the rear wheel motor drive rotation in existing two-wheeled electric vehicles, so it will not be described in detail. A front bearing seat 5 and a rear bearing seat 6 are mounted on the base frame 1. The reclining frame 2 is rotatably mounted on the base frame 1 through the front bearing seat 5 and the rear bearing seat 6. A drive gear 7 is mounted on the reclining frame 2. The drive gear 7 can be a whole gear, or... To meet the requirements of the semi-circular gear, a hydraulic cylinder 8 is installed on the base frame 1. The hydraulic cylinder 8 is a hydraulic cylinder with two output ends that do not extend or retract simultaneously. A rack 9 is installed on the output end of the hydraulic cylinder 8. The rack 9 meshes with the drive gear 7. A connecting block 10 is rotatably installed on the reclining frame 2. A tripod 11 is rotatably installed on the connecting block 10. Steering support rods 12 are installed at both ends of the bottom of the tripod 11. An mounting block 13 is rotatably installed on the base frame 1. The front wheel 4 is rotatably installed on the mounting block 13. The steering support rod 12 is hinged to the front wheel 4 through a fisheye bearing 14. A left brake 15 and a right brake 16 are hinged on the reclining frame 2. A brake fluid reservoir 161 is installed on the reclining frame 2. An oil brake 17 is installed on the front wheel 4. The left brake 15, the right brake 16, the brake fluid reservoir 161, and the oil brake 17 are all connected through oil pipes.
[0024] In this embodiment, the driver lies in a reclining position on the reclining frame 2 to drive the three-wheeled vehicle. The drive motor on the rear wheel 3 drives the rear wheel 3 to rotate and move forward, serving as the power source for the entire three-wheeled vehicle's movement. The reclining frame 2 is mounted on the base frame 1 through the rotational bearing capacity of the front bearing seat 5 and the rear bearing seat 6. When turning is required, the output end on the other side of the rotation direction is extended by the hydraulic cylinder 8, thereby driving the rack 9 to move. The moved rack 9 drives the drive gear 7 on the reclining frame 2 to rotate, so that the entire reclining frame 2 can guide the driver to face the direction of turning, thus preventing the driver from being thrown out by centrifugal force. When the reclining frame 2 rotates, it can drive the tripod 11 on the connecting block 10 to rotate. The entire tripod 11 moves in an arc-shaped upward trajectory around the gear 7 and is driven upward by the connecting block 10, thus providing steering support on both sides of the tripod 11. The lever 12 can pull or push the two front wheels 4 to adjust their direction, thus allowing them to turn while moving forward. When the turning space is small, the driver can press the brake on the turning side, i.e., the left brake 15 or the right brake 16, thereby applying pressure to the hydraulic brake 17 on one side of the front wheel 4 through the brake fluid reservoir 161. This stops the front wheel 4 on the turning side, leaving only the other front wheel 4 to turn forward. At this time, the three-wheeled vehicle can achieve a 360° turn on the spot. When the front wheels 4 are adjusted in direction, it is achieved by rotating the mounting block 13 on the base frame 1. The spherical bearing 14 is used to rotate the support rod 12, which is driven to rise and fall, and can be adjusted to a certain angle when the front wheels 4 are turning.
[0025] In some embodiments, to facilitate driver control of steering, a rotary control lever 18 is installed on the reclining frame 2, and a comprehensive controller 19 and a steering pump station 20 are installed on the base frame 1. The steering pump station 20 can be a miniature oil pump. The control lever 18, the comprehensive controller 19, and the steering pump station 20 are electrically connected. The steering pump station 20 is connected to both output ends of the hydraulic cylinder 8 via oil supply pipes. When the driver rotates the rotary control lever 18, the rotation transmits a signal to the comprehensive controller 19, which then drives the steering pump station 20 to supply oil to the hydraulic cylinder 8, thereby controlling the operation of the hydraulic pump 8.
[0026] In some embodiments, to facilitate control of the rotation direction, a left and right oil pump control valve 21 is installed on the rotary pump station 20. The left and right oil pump control valve 21 controls the rotary oil pump 20 to deliver oil to one side of the two ends of the hydraulic oil pump 8, thereby precisely controlling which end of the hydraulic oil pump 8 extends to drive the rack 9 to move.
[0027] In some embodiments, to facilitate control of the maximum rotation angle of the reclining frame 2 when it is driven to rotate by the gear 7, two collision sensors 22 are installed on the base frame 1. The detection ends of the two collision sensors 22 are located outside the two output ends of the hydraulic cylinder 8, and the collision sensors 22 are electrically connected to the integrated controller 19. After the hydraulic cylinder 8 drives the rack 9 to contact the collision sensor 22, the integrated controller 19 prevents the hydraulic cylinder 8 from extending and working.
[0028] In some embodiments, to facilitate power supply to the drive motor on the rear wheel 3 and the integrated controller 19, a first battery 30 and a second battery 23 are installed on the base frame 1. The first battery 30 is electrically connected to the drive motor on the rear wheel 3, and the second battery 23 is electrically connected to the integrated controller 19, collision sensor 22, etc.
[0029] In some embodiments, to facilitate the driver's precise application of the left brake 15 and right brake 16, limit frames 24 are installed on both the left brake 15 and right brake 16. This limits the driver's feet and prevents them from slipping off the left brake 15 and right brake 16 when the recumbent frame 2 rotates.
[0030] In some embodiments, to reduce friction between the rear wheel 3 and the ground during steering, a water tank control switch 25 is installed on both the left brake 15 and the right brake 16. A water tank 26 is installed on the chassis 1, and a water pump is installed inside the water tank 26. The water tank control switch 25 is electrically connected to the water pump. A water spray nozzle 27 is installed on the chassis 1, and the water spray nozzle 27 is configured to cooperate with the rear wheel 3. The water tank 26 and the water spray nozzle 27 are connected by a water pipe. When the driver presses the left brake 15 and the right brake 16, they will also press the water tank control switch 25, thereby controlling the water pump in the water tank 26 to work, delivering water to the water spray nozzle 27 and spraying it out. The water pump can be electrically connected to the second battery 23.
[0031] In some embodiments, to protect the driver, a seatbelt crossbar 28 is installed on the reclining frame 2, and a protective frame is also installed on the reclining frame 2. This allows the seatbelt to pass through different seatbelt crossbars 28, thus accommodating drivers of different body types.
[0032] In some embodiments, to facilitate control of the forward speed of the three-wheeled vehicle, a throttle control lever 29 is installed on the reclining frame 2. The throttle control lever 29 is electrically connected to the battery 30 and the integrated controller 19.
[0033] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
