At the same time, the direction control device 5 can pull the double-wheel suspension structure 3 to deflect while controlling the steering of the front wheel 21 on the single-wheel suspension structure 2, so that the body 1 can tilt toward the steering side, so that the overall force of the vehicle is balanced, damage to structural components is avoided, the service life is extended, the control is more convenient, and the occurrence of safety accidents such as rollover is avoided. At the same time, the counterweight of the vehicle is increased, the stability of the vehicle is improved, the safety is higher, and it is more conducive to the use and promotion of the vehicle.

[0035] Specifically, the vehicle body 1 has a front end and a rear end, and the vehicle body 1 provides an installation carrier for the single-wheel suspension structure 2, the double-wheel suspension structure 3, the adjustment component 4 and the steering control device 5, which facilitates the assembly of the above structures and, at the same time, increases the vehicle's counterweight to ensure the stability of the vehicle's operation.

[0036] Specifically, the single-wheel suspension structure 2 is arranged at the front end of the vehicle body 1, and the single-wheel suspension structure 2 is provided with a front wheel 21, so that the single-wheel suspension structure 2 and the front wheel 21 arranged thereon serve as the front structure of the vehicle, providing a structural basis for supporting the front of the vehicle and steering. In addition, the double-wheel suspension structure 3 is arranged at the rear end of the vehicle body 1, and rear wheels 31 are arranged on and on both sides of the double-wheel suspension structure 3. At this time, the double-wheel suspension structure 3 and the rear wheels 31 arranged thereon serve as the rear structure of the vehicle, providing a structural basis for supporting the rear of the vehicle, and the rear wheels 31 are arranged on both sides of the double-wheel suspension structure 3, ensuring that the two rear wheels 31 and the one front wheel 21 are distributed in an isosceles triangle structure, ensuring the stability of the vehicle in static and moving states, and the structural design is more reasonable.

[0037] Figure 3 FIG. 1 is a structural diagram of an adjustment component of a preferred embodiment of the present invention. Figures 1 to 3As shown, the adjustment component 4 is arranged at the rear end of the vehicle body 1, which is conducive to the adjustment component 4 acting on the two-wheel suspension structure 3, and the adjustment component 4 includes a swing rod 41 and a return spring 42. One end of the swing rod 41 is hinged on the vehicle body 1 and fixedly connected to the two-wheel suspension structure 3, so that the swing rod 41 can swing on the vehicle body 1. At the same time, the swing rod 41 can drive the two-wheel suspension structure 3 to deflect relative to the plane where the vehicle body 1 is located, that is, when the plane (ground) where the two rear wheels 31 on the two-wheel suspension structure 3 are located remains unchanged, the vehicle body 1 can tilt relative to the ground, so that the posture change of the vehicle body 1 can adapt to the driving needs of the vehicle, so that the vehicle body 1 can adapt to the force change during the turning process, so that the centrifugal force and the centripetal force of the vehicle are equal, so that the overall force of the vehicle is more balanced, the damage of the structural components of the vehicle is avoided, the service life is extended, and the problem of rollover during the steering process of the vehicle is prevented, the safety guarantee is higher, and the counterweight of the vehicle is further increased, so that the structural process of the vehicle is more reasonable and the safety is higher. In addition, a return spring 42 is provided between the other end of the swing arm 41 and the vehicle body 1, so that after the swing arm 41 swings, it can be reset under the action of the elastic force of the return spring 42, thereby improving the controllability of the vehicle and making the structural design more reasonable.

[0038] Figure 4 FIG. 1 is a structural diagram of a direction control device according to a preferred embodiment of the present invention. Figures 1 to 4As shown, the direction control device 5 is arranged on the vehicle body 1, and the direction control device 5 includes a rocker 51, a push-pull rod 52 and a cable 53. At this time, the lower end of the rocker 51 is hinged on the vehicle body 1 and is located between the front end and the rear end, so that the rocker 51 can rotate around its hinge point on the vehicle body 1, and the rotation direction of the rocker 51 is from the front end to the rear end or from the rear end to the front end of the vehicle body 1, so that the end of the rocker 51 away from the vehicle body 1 can be rotated to a state close to the front end and away from the rear end, or the end of the rocker 51 away from the vehicle body 1 can be rotated to a state away from the front end and close to the rear end, so as to adapt to different steering requirements. In addition, the push-pull rod 52 is arranged between the upper end of the rocker arm 51 and the front wheel 21, and the two ends of the push-pull rod 52 are respectively hinged to the front wheel 21 and the rocker arm 51, so that when the rocker arm 51 is pushed toward the front end side, the push-pull rod 52 can move toward the front end side of the vehicle body 1, thereby pushing the front wheel 21 to deflect toward the side opposite to the side where the push-pull rod 52 is located, thereby realizing the front wheel 21 turning to one side, and when the rocker arm 51 is pushed toward the rear end side, the push-pull rod 52 can move toward the side of the rear end of the vehicle body 1, thereby pulling the front wheel 21 to deflect toward the side where the push-pull rod 52 is located, thereby realizing the front wheel 21 turning to the other side. The cable 53 is arranged between the upper end of the rocker arm 51 and the double-wheel suspension structure 3, and the two ends of the cable 53 are respectively connected to the upper end of the rocker arm 51 and one end of the rocker arm 41 provided with a return spring 42, so that when the rocker arm 51 rotates, the rocker arm 41 can be pulled by the cable 53 to swing, thereby realizing the adjustment of the tilt state of the vehicle body 1. That is, when the rocker arm 51 is pushed toward the front end side of the vehicle body 1, the front wheel 21 is pulled by the push-pull rod 52 to deflect toward the side opposite to the side where the towing rod is located. At the same time, the rocker arm 51 can pull the rocker arm 41 to deflect toward the side where the rocker arm 41 is located through the cable 53 connected thereto, thereby making the vehicle body 1 tilt toward the side in the same direction as the steering direction of the front wheel 21, so that the vehicle adapts to the steering force environment, the force is more balanced, the damage of structural components is prevented, and safety accidents such as rollover are avoided. In addition, the deflected rocker arm 41 can be reset under the action of the return spring 42 after the turn is completed, which provides conditions for the normal use of the vehicle.

[0039] More specifically, two groups of return springs 42 are provided for returning the rocker arm 41, and the two groups of return springs 42 are symmetrically arranged on both sides of the rocker arm 41, and the two groups of return springs 42 are respectively connected to the two sides of the rear end of the vehicle body 1 at one end away from the rocker arm 41, so that when the rocker arm 41 deflects following the turning of the front wheel 21, the return springs 42 on both sides can ensure that the rocker arm 41 can be returned to its original position after swinging to either side, which is suitable for the use environment where the front wheel 21 turns to either side, and the structural design is more reasonable.

[0040] More specifically, two groups of steering control devices 5 for achieving steering of the front wheels 21 are also provided. The two groups of steering control devices 5 are symmetrically arranged on both sides of the vehicle body 1 to facilitate the driver and passengers to drive with both hands, and the two push-pull rods 52 of the two groups of steering control devices 5 are respectively hinged on both sides of the front wheels 21, so that the two push-pull rods 52 can act on the front wheels 21 at the same time. At the same time, the two cables 53 of the two groups of steering control devices 5 are respectively connected to the two sides of the rocker arm 41, so that the rocker arm 41 can be pulled toward the corresponding side by the two cables 53. At this time, when the vehicle turns right, the driver and passengers push the rocker arm 51 on the left side of the vehicle body 1 to rotate toward the front end of the vehicle body 1, and the push-pull rod 52 hinged to the left rocker arm 51 also moves toward the front end of the vehicle body 1, thereby pushing the front wheel 21 to deflect toward the right side, realizing the right turn of the vehicle. At the same time, the rocker arm 51 can pull the cable 53, so that the cable 53 can pull the swing rod 41 to deflect toward the left side, thereby making the vehicle body 1 tilt toward the right side, so that the vehicle adapts to the force requirements of steering, and in this process, the driver and passengers pull the rocker arm 51 on the right side of the vehicle body 1 to rotate toward the rear end of the vehicle body 1, and the push-pull rod 52 hinged to the right rocker arm 51 also moves toward the rear end of the vehicle body 1, thereby pulling the front wheel 21 to deflect toward the right side, also realizing the right turn of the vehicle, and the cable 53 connected to the right rocker arm 51 is in a relaxed state, which will not affect the deflection of the swing rod 41, thereby ensuring the reliability of the tilting of the vehicle body 1. Similarly, when the vehicle turns left, the driver pushes the rocker 51 on the right side of the vehicle body 1 to rotate toward the front end of the vehicle body 1, and pulls the rocker 51 on the left side of the vehicle body 1 to rotate toward the rear end of the vehicle body 1. The control process is opposite to the above-mentioned right turn control process, which also ensures the force balance of the vehicle when turning left, and the structural design is more reasonable.

[0041] More specifically, the direction control device 5 also includes a sleeve 54, which is arranged on the vehicle body 1 and between the rocker 51 and the swing arm 41. The two ends of the sleeve 54 extend to the rocker 51 and the rear end of the vehicle body 1 where the swing arm 41 is arranged, respectively. In addition, the cable 53 is passed through the sleeve 54, that is, the cable 53 is protected by the sleeve 54, which prevents the cable 53 from being exposed to the outside and easily damaged. At the same time, it also improves the neatness and aesthetics of the vehicle, and the structural design is more reasonable.

[0042] In addition, to facilitate the installation of the return spring 42 and the cable 53, a vertically upward column 43 is provided on the rear end of the vehicle body 1, and the end of the return spring 42 that is away from the rocker arm 41 is connected to the column 43. At the same time, the end of the cable 53 that is connected to the rocker arm 41 first passes through the column 43 and then is connected to the rocker arm 41.

Steering wheels 214 are arranged on both sides of the hub of the wheel body 211, that is, the hub of the wheel body 211 is clamped by two steering wheels 214. At the same time, steering connecting parts 2141 are arranged on the two steering wheels 214 and on the sides away from each other, and the two steering connecting parts 2141 are respectively hinged to the two push-pull rods 52, so that the push-pull rod 52 can drive the wheel body 211 to deflect toward the corresponding side through the steering connecting part 2141, so as to realize the steering of the wheel. At the same time, a penetrating flat hole 2142 is provided on the two steering wheels 214 along the axial direction of the wheel body 211, and the flat shaft 212 is inserted into the flat hole 2142 of the two steering wheels 214, so that the overall structure formed by the two steering wheels 214 clamped with the wheel body 211 can be installed on the flat shaft 212 through the flat hole 2142. At the same time, the rotation direction of the overall structure formed by the two steering wheels 214 clamped with the wheel body 211 on the flat shaft 212 can be limited, providing a structural basis for subsequent steering. In addition, both ends of the flat shaft 212 extend out from the two flat holes 2142 respectively. At the same time, a vertical steering shaft 213 is provided in the middle of the flat shaft 212, and an arc groove 2143 connecting the flat hole 2142 is provided on each steering wheel 214 along the direction in which the vertical flat hole 2142 penetrates. The arc grooves 2143 on the two steering wheels 214 are arranged opposite to each other and form a circular hole, and the steering shaft 213 is arranged in the circular hole formed by the two arc grooves 2143, so that the two steering wheels 214 can rotate around the axial direction of the steering shaft 213 on the flat shaft 212, thereby realizing the steering of the driving wheel body 211, and the structural design is more reasonable.

[0044] More specifically, the single-wheel suspension structure 2 arranged at the front end of the vehicle body 1 and used to install the front wheel 21 includes a connecting arm 22, a front shock absorber 23 and a front support frame 24. The front support frame 24 is arranged on the vehicle body 1 and protrudes upward from the vehicle body 1. One end of the connecting arm 22 is hinged to the front end of the vehicle body 1 and extends outward. The other end of the connecting arm 22 is rotatably connected to one end of the flat shaft 212 extending out of the flat hole 2142. One end of the front shock absorber 23 is hinged to one end of the connecting arm 22 connected to the flat shaft 212, and the other end of the front shock absorber 23 is hinged to the front support frame 24, so that the front shock absorber 23, the connecting arm 22 and the front support frame 24 form a triangular structure, which improves the stability of the single-wheel suspension structure 2 and facilitates the installation of the front wheel 21.

[0045] More specifically, two groups of connecting arms 22 and front shock absorbers 23 are provided, and the two groups of connecting arms 22 are symmetrically arranged on both sides of the vehicle body 1. The two groups of connecting arms 22 are rotatably connected to the two ends of the flat shaft 212, respectively, so that both ends of the flat shaft 212 of the front wheel 21 can be supported by the single-wheel suspension structure 2, so that the force on the front wheel 21 is more uniform, and the service life of the front wheel 21 is extended. At the same time, one group of connecting arms 22 corresponds to one group of front shock absorbers 23, and the two ends of the front shock absorber 23 are respectively hinged to the connecting arms 22 and the front support frame 24 on the corresponding side, so that each connecting arm 22 corresponds to a front shock absorber 23, which not only improves the supporting strength of the single-wheel suspension structure 2 and has a stronger load-bearing capacity, but also improves the shock absorbing ability of the single-wheel suspension structure 2 and has a higher riding comfort.

At this time, the rear connecting portion 32 is disposed in the middle of the rear end of the vehicle body 1 and extends outward, so that the rear connecting portion 32 can serve as the main supporting structure of the double-wheel suspension structure 3, and the side support frames 33 are hinged on both sides of the rear connecting portion 32, and the wheel mounting portion is disposed at one end of the side support frame 33 away from the rear connecting portion 32. The rear connecting portion 32 is provided with a rear wheel 31, that is, the rear wheels 31 are installed on both sides of the rear end of the vehicle body 1 through the support frames 33 on both sides. At the same time, the top of the rear connecting portion 32 is hinged with a connecting shaft 37 arranged along the direction from the front end to the rear end of the vehicle body 1, so that the connecting shaft 37 can rotate on the rear connecting portion 32 with the longitudinal direction from the front end to the rear end of the vehicle body 1 as the axis, and one end of the deflection portion 36 is fixedly connected to the connecting shaft 37, so that the connecting shaft 37 can drive the deflection portion 36 to deflect. At the same time, the two sides of the other end of the deflection portion 36 are respectively hinged with a rear shock absorber 35, and the other end of the rear shock absorber 35 is hinged to the side support frame 33 on the corresponding side, so that during the driving of the vehicle, the deflection portion 36 can also deflect under the action of the rear shock absorber 35, so as to adapt to the bumpy road surface. At the same time, one end of the connecting shaft 37 is also fixedly connected to the end of the rocker arm 41 away from the reset spring 42, so that the deflection of the rocker arm 41 can act on the deflection part 36 through the connecting shaft 37, that is, the deflection part 36 can be controlled by the rocker arm 51 to deflect, thereby causing the two-wheel suspension structure 3 to deflect and the vehicle body 1 to tilt, thereby meeting the force requirements of vehicle steering and making the structural design more reasonable.

[0047] More specifically, the support frame on each side of the rear connecting part 32 includes an upper support frame 331 and a lower support frame 332, and the upper support frame 331 and the lower support frame 332 are distributed in upper and lower layers, and the two ends of the upper support frame 331 are respectively hinged to the upper part of the rear connecting part 32 and the upper part of the wheel mounting part 34 on the corresponding side, and the two ends of the lower support frame 332 are respectively hinged to the lower part of the rear connecting part 32 and the lower part of the wheel mounting part 34 on the corresponding side, and the end of the rear shock absorber 35 away from the connection deflection part 36 is hinged to the upper support frame 331 or the end of the lower support frame 332 hinged to the wheel mounting part 34, so that the support structure on each side is a double-layer structure, which can not only prevent the wheel mounting part 34 from rotating in the vertical plane, but also improve the structural strength of the side double-wheel suspension structure 3, with stronger load-bearing capacity and more solid structure.

[0048] More specifically, a seat 6 is provided on the vehicle body 1 and between the rocker 51 and the two-wheel suspension structure 3, providing a seating space for the driver and passengers. At the same time, the rocker 51 for controlling the direction is located on the front side of the seat 6, which is convenient for the driver and passengers to control, improves the riding experience, and provides higher riding comfort.

[0049] In addition, different types of return springs 42 can be selected to meet different steering requirements of the vehicle, that is, the swing amplitude of the swing bar 41 can be adjusted by replacing different types of springs, thereby controlling the inclination of the vehicle body 1, and the structural design is more reasonable. Moreover, during the low-speed steering of the vehicle, the cable 53 and the return spring 42 can also tighten the swing bar 41 to limit the movement of the swing bar 41, thereby limiting the deflection of the two-wheel suspension structure 3 connected to the swing bar 41, and preventing safety accidents such as rollover caused by excessive deflection of the two-wheel suspension structure 3 during the steering process. When the vehicle is driving straight at high speed, the cable 53 and the return spring 42 will not impose excessive restrictions on the swing bar 41, and the two-wheel suspension structure 3 can deflect more freely, thereby adapting to the ups and downs of the road, reducing the vibration of the vehicle, and improving the riding experience.

[0050] The manual three-wheeled motorcycle provided in this embodiment includes a body 1, a single-wheel suspension structure 2, a double-wheel suspension structure 3, an adjustment component 4 and a direction control device 5; the single-wheel suspension structure 2 with a front wheel 21 and the double-wheel suspension structure 3 with a rear wheel 31 are respectively arranged at the front end and the rear end of the body 1, and the adjustment component 4 connected to the double-wheel suspension structure 3 and the direction control device 5 for controlling the steering of the front wheel 21 and acting on the adjustment component 4 are arranged on the body 1, so that when the front wheel 21 turns, the adjustment component 4 can be pulled by the cable 53 in the direction control device 5, so that the adjustment component 4 drives the double-wheel suspension structure 3 to deflect toward the opposite side of the steering direction, so that the body 1 tilts toward the steering direction, so that the overall force of the vehicle is more balanced, damage to structural components is prevented, the service life of the vehicle is extended, and the occurrence of safety accidents such as rollover is avoided. At the same time, the counterweight of the vehicle is increased, so that the stability of the vehicle is higher, which is more conducive to the use and promotion of the vehicle.

Those skilled in the art should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
