Description

Technical Field

[0001] The invention relates to the technical field of electric vehicles and motorcycles, and in particular to a mechanical 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 object of the present invention is to provide a mechanical parking mechanism for a three-wheeled vehicle, which solves the problem of unstable parking by directly fixing the wheels.

[0007] The object of the present invention is achieved as follows: A mechanical parking mechanism for a three-wheeled vehicle includes a frame vertical pipe and a wheel disposed on one side thereof. A sleeve is installed on one side of the frame vertical pipe, and a connecting rod is movably disposed within the sleeve. A shock absorber is installed on the wheel, and the lower end of the connecting rod is connected to the connection point between the shock absorber and the wheel. A stop member is disposed on one side of the connecting rod, and a plurality of limiting grooves for the stop member to snap into are formed on the connecting rod. The stop member is connected to a parking pull rope that drives its movement, and the other end of the parking pull rope is connected to a parking handle. Operating the parking handle causes the stop member to snap into the limiting groove to restrict the relative movement between the sleeve and the connecting rod.

[0008] Preferably, the middle part of the stop member is rotatably disposed on the sleeve, and a limiting claw is formed at one end of the stop member.

[0009] Preferably, the parking pull rope includes an upper pull rope and a lower pull rope. The upper end of the stop member is connected to the upper pull rope, and the lower end of the stop member is connected to the lower pull rope. The other ends of the upper pull rope and the lower pull rope are respectively connected to the parking handle.

[0010] Preferably, the upper end of the sleeve is connected to the frame vertical pipe through an upper joint bearing.

[0011] Preferably, the shock absorber includes a piston sleeve and a piston rod movably disposed within it. The lower end of the sleeve is connected to the piston sleeve through a lower joint bearing.

[0012] The prominent and beneficial technical effects of the present invention compared with the prior art are:

[0013] Through the design of the mechanical parking structure, during actual use, by operating the parking handle, the stop member can be snapped into the limiting groove, thereby restricting the relative movement between the sleeve and the connecting rod, fixing the position between the frame vertical pipe and the wheel, achieving the parking effect, avoiding the movable structure at the shock absorption part, and being able to achieve a more stable parking effect.

[0020] The following further describes in detail the specific embodiments of the present invention with reference to the accompanying drawings.

[0021] As Figure 1 , Figure 2 shown, a mechanical parking mechanism for a three - wheel vehicle includes a frame riser 1 and a wheel 2 disposed on one side thereof. A sleeve 3 is installed on one side of the frame riser 1. A connecting rod 4 is movably disposed within the sleeve 3. A shock absorber 5 is installed on the wheel 2. The sleeve 3 and the connecting rod 4 are disposed between the frame riser 1 and the shock absorber 5. The lower end of the connecting rod 4 is connected between the connection points of the shock absorber 5 and the wheel 2. A stopper 6 for restricting the movement of the connecting rod 4 is disposed on one side of the connecting rod 4. A plurality of limiting grooves 7 for the stopper 6 to snap into are formed on the connecting rod 4. The stopper 6 is connected to a parking pull - rope 8 that drives its movement. The other end of the parking pull - rope 8 is connected to a parking handle 9. During actual use, by operating the parking handle 9, the stopper 6 can be snapped into the limiting groove 7, thereby restricting the relative movement between the sleeve 3 and the connecting rod 4, fixing the position between the frame riser and the wheel, achieving the effect of parking, thus avoiding the moving structure at the shock - absorbing part and enabling a more stable parking effect.

[0022] Combined with Figure 2 and Figure 3 , the middle part of the stopper 6 is rotatably disposed on the sleeve 3. One end of the stopper 6 is formed with a limiting claw 10 for snapping into the limiting groove 7 for limiting.

[0023] Combined with Figure 2 and Figure 3 , the parking pull - rope 8 includes an upper pull - rope 8a and a lower pull - rope 8b. The upper end of the stopper 6 is connected to the upper pull - rope 8a, and the lower end of the stopper 6 is connected to the lower pull - rope 8b. The other ends of the upper pull - rope 8a and the lower pull - rope 8b are respectively connected to the parking handle 9. When the parking handle 9 is rotated in one direction, the stopper 6 will be driven to rotate through the lower pull - rope 8a, so that the limiting claw 10 snaps into the limiting groove 7. When the parking handle 9 is rotated in the other direction, the stopper 6 will be driven to rotate through the upper pull - rope 8b, so that the limiting claw 10 leaves the limiting groove 7. The installation structure and working principle of the parking handle 9 are common knowledge, so they will not be specifically described herein.

[0024] Combined with Figure 1 and Figure 2 , the upper end of the sleeve 3 is connected to the frame riser 1 through an upper joint bearing 11, thus realizing a movable connection.

[0025] Combined with Figure 1 and Figure 2 , the shock absorber 5 includes a piston sleeve 5a and a piston rod 5b movably disposed therein, and the lower end of the sleeve 3 is connected to the piston sleeve 5a through a lower joint bearing 12.
