Further, the projections of the two third pivot points 140d and the two ball joints 140c of the present embodiment on a plane perpendicular to the vertical direction D2 (for example, the plane of the paper surface of FIG. 6) are defined. Out of the isosceles trapezoid L. Wherein, the connection of the projections of the two third pivot points 140d on the plane is the upper base of the isosceles trapezoid L, and the connection of the projections of the two ball joints 140c on the plane is waited for The lower base of the waist trapezoid L. In other words, the distance between the two ball joints 140c is designed to be greater than the distance between the two third pivot points 140d.

Under this configuration, when the motorcycle 100 is turned from the state shown in FIG. 6 to the state shown in FIG. 7, the angle A of the left front wheel 160 is slightly larger than the angle B at which the right front wheel 160 is rotated. Therefore, by the slight difference in the steering angle between the two front wheels 160, the outer front wheel 160 (in the steering mode of FIG. 7, the outer front wheel 160 is the right front wheel 160) can be reduced from sliding relative to the ground when the motorcycle 100 is turned. The degree is to make the user smoother during the steering process and reduce the wear of the front wheel 160.

The two second links 284 are respectively pivotally connected to the two first links 282 in the vertical direction D2, and are respectively located on two sides of the body 210. The two clamping members 286 are respectively pivotally connected to the two second links 284 in the vertical direction D2 and collectively clamp the body 210 to prevent the main body 210 from rotating in the horizontal direction D1. In other words, the first lever member 220, the second lever member 230, and the tilting member 240 are thus restricted from being actuated, and the three-wheeled motor vehicle 200 is in the parked state and cannot be tilted. Thereby, the situation in which the three-wheeled motor vehicle 200 is dumped at rest can be avoided to improve the safety and convenience of the user (such as a disabled person) driving the three-wheeled motor vehicle 200.

When the user wants to release the parking state, the two first links 282 and the second connection can be pushed by the two actuating members 288 disposed on the first rod 220 to resist the elastic forces of the two elastic members 289, respectively. The lever 284 is rotated to the state shown in FIG. 9 to drive the two clamping members 286 away from the main body 210. At this time, the main body 210 is no longer restricted by the clamping member 286, so the main body 210, the first rod member 220, the second rod member 230, and the tilting member 240 can be actuated from the state shown in FIG. 8 to the state shown in FIG. The motor vehicle 200 achieves the inclination of the vehicle body.

When the user wants to park again, the pushing action of the actuating member 288 on the first link 282 and the second link 284 can be released. At this time, as the main body 210 is rotated from the state shown in FIG. 9 to the state shown in FIG. 8, the first link 282, the second link 284, and the holding member 286 are reset by the elastic force of the elastic member 289. The state shown in Fig. 8 is to limit the main body 210 to be unable to rotate in the horizontal direction D1. The actuating member 288 of the present embodiment may be, for example, an electromagnetic switch. However, the present invention is not limited thereto, and in other embodiments, it may be other suitable components that can achieve the same effect. In addition, the elastic member 289 of the embodiment may be, for example, a torsion spring. However, the present invention is not limited thereto, and in other embodiments, it may be other suitable components that can achieve the same effect.

In summary, in the present invention, the first pivot member and the second member are configured by arranging the positions of the first pivot joint, the second pivot joint, and the ball joint of the two wheel seats in a rectangular manner. When the two wheel seats and the main body are tilted relative to the translation, the steering rod does not cause the wheel base to turn. Thereby, the inclination of the vehicle body can be avoided to cause the front wheel to generate a steering behavior that is not expected by the user, and the handling of the three-wheeled motor vehicle can be improved, and the probability of accidents during driving can be reduced.

In addition, the present invention is configured by arranging the positions of the third pivot point and the ball joint of the two steering members in an isosceles trapezoidal shape, so that the steering angle of the two front wheels is slightly different when the motorcycle is turned to reduce When the motorized tricycle turns, the outer front wheel slides relative to the ground, which makes the steering process smoother and reduces the wear of the front wheel.

In addition, the three-wheeled motor vehicle of the present invention can be further equipped with a parking mechanism, and the holding member of the parking mechanism can be used to limit the main body for parking operation, and can avoid the situation that the three-wheeled motor vehicle is dumped at rest and improve the use. Safety and convenience when driving a three-wheeled motor vehicle. When the user wants to release the parking state, the three-wheeled motor vehicle can be tilted by the two actuating members pushing the first link and the second connecting rod to drive the clamping member away from the main body.

The present invention utilizes the above simple mechanism design to improve the handling and safety of the three-wheeled motor vehicle, and therefore has the advantage of low cost, so that the low-income, vulnerable and vulnerable groups can also enjoy safer and more convenient means of transportation.

Although the present invention has been disclosed in the above embodiments, it is not intended to limit the invention, and any one of ordinary skill in the art can make some modifications and refinements without departing from the spirit and scope of the invention. The scope of the invention is defined by the scope of the appended claims.
