Description

Technical Field

[0001] The invention relates to the technical field of electric vehicles and motorcycles, and in particular to a parking mechanism for three-wheeled vehicles. Background Art

[0002] A dual front wheel vehicle refers to a new type of vehicle with two steering front wheels and at least one driving rear wheel. In the prior art, dual front wheel vehicles generally adopt the principle of "parallelogram multi-axis multi-rod linkage". The two front wheels responsible for steering are connected to the front standpipe at the front end of the frame using a unique tiltable rocking device, and the variable parallelogram structure is used to achieve the same sideways bending as a traditional two-wheeled motorcycle. Unlike a triangle, a parallelogram is unstable and can deform under the action of external force, and the two opposite sides will always remain parallel during deformation. It is precisely by utilizing this principle that the two front wheels of a dual front wheel vehicle can be tilted to the left and right without being restricted by the frame and shock absorbers when turning, and the three wheels of the vehicle always remain in contact with the ground, so that the vehicle generates a sufficiently large positive pressure on the ground through the wheels to balance the centrifugal force on the vehicle, thereby effectively improving the vehicle's ability to resist rollover when turning.

[0003] Although this parallelogram-structured swaying device can improve the stability and safety of dual front-wheel vehicles when driving, especially when turning, when the dual front-wheel vehicle needs to be parked, the instability of the parallelogram makes it easy for the swaying device of the dual front-wheel vehicle to tilt left and right, making it difficult for the entire vehicle body to remain upright, and the stability of the dual front-wheel vehicle when parked cannot be guaranteed.

[0004] Therefore, in the prior art, a parking mechanism is usually added to fix the wheels so that the vehicle can remain stable when parked. For example, a Chinese utility model patent with the patent number CN207208339U discloses a parking lock structure for a double front-wheel electric vehicle or motorcycle. By pressing down the handle and pulling the wire to drive the tail of the parking block to move, the parking block is rotated around the first lock frame through the pivot portion, and the locking portion rises to resist the lower end of the linkage member. The linkage member is laterally fixed and cannot swing. In this way, the entire independent suspension system is fixed to achieve the parking effect.

[0005] The above solution achieves the parking effect by fixing the independent suspension system, but since the shock absorbing device on the wheel can still move, it will cause unstable parking, so the structure needs to be further improved. Summary of the invention

[0006] The purpose of the present invention is to provide a parking mechanism for a three-wheeled vehicle, which solves the problem of unstable parking by means of a brake assembly.
