Coupler with adjustable tilt angle of tricycle

The present invention relates to a coupler with an adjustable tilt angle of a tricycle, in particular to a tilt limit block for applying a locking angle to a thread of a fixed shaft of a front and rear frame, and The tilt limit block of the tilt angle is changed according to the frame.

At present, the tricycle has a front wheel and two rear wheels/two front wheels and one rear wheel, so that the rider can be given a perfect balance and safety. Most tricycles drive the car forward or backward by pedaling the rider or by running the motor or engine. When the tricycle is bent, the wheels must be attached to the road. If one of them is suspended, the car will be overturned. Therefore, the tricycle cannot be bent in an inward manner like a two-wheeled vehicle, and the speed must be reduced when cornering, and the wear of the deceleration system of the tricycle is increased.

At present, some organizations have been able to provide tricycles to bend in an inward manner. For example, the Republic of China Invention Patent Publication No. I274677 discloses a structure in which an independent suspension wheel and a vehicle body are tilted together, including a link mechanism and an independent suspension wheel mechanism. The link mechanism includes an upper floating rod and is located below the upper floating rod and a bottom rod parallel to the upper floating rod and a connecting member; two ends of the upper floating rod and the bottom rod are respectively pivotally connected to the rocker to form a quadrilateral structure, and the connecting member has a protruding slider and is centrally connected with the upper floating rod The position has a sliding groove extending upwardly and downwardly, and the bottom of the connecting member is pivotally connected to the central position of the bottom rod; the independent hanging wheel mechanism is mainly composed of a shock absorber, a suspension connecting rod and a hub, and the wheel hub is suspended by the suspension The connecting rod and the rocker are pivotally connected, and the top and bottom of the shock absorber are respectively pivotally connected On the top of the rocker and the bottom area of the hub or its attached suspension link. For example, the anti-overturning three-wheeled motor vehicle disclosed in the Republic of China Invention Patent Publication No. I410339 has a frame, a front wheel, and a rear two-wheel assembly including a tilting base and a four-bar linkage; The first fixing frame is connected to the frame, the four-bar linkage mechanism is used for connecting the frame and the rear two wheels, and comprises a first connecting rod, a second connecting rod, a third connecting rod and a fourth connecting rod; the first connecting rod The second link is pivotally connected to the inward tilting base, and the third link and the fourth link are respectively pivotally connected to the two ends of the first link and the second link, and are respectively connected to the suspension of the second wheel, When the frame is tilted, the tilting base and the first fixing frame are inclined with the frame, so that the first link and the second link maintain a fixed angle with the road surface, and the third link and the fourth link are followed by the vehicle. The frame is tilted so that the rear two wheels are kept wide while being tilted with the frame. However, the above-mentioned link mechanism and the four-bar linkage mechanism mainly cause the front wheel and the second rear wheel of the tricycle to be inwardly tilted at the time of cornering, which may cause uneven wear of the two rear wheels and affect driving safety. Moreover, these conventional mechanisms do not have any inclination limit mechanism, and even a mechanism for adjusting the angle of inclination of the frame according to the actual structure of the frame. Therefore, when the tricycle of the conventional structure is bent, the body is easy to be used. Overturned and overturned.
