Description

Technical Field

[0001] This utility model relates to the field of reverse tricycle scooter technology, and in particular to an independent front suspension mechanism for a side-tilting reverse tricycle scooter. Background Technology

[0002] Tricycles have gained attention for their superior initial stability compared to two-wheeled scooters. However, the front suspension mechanisms of traditional tricycles often have limitations. Many designs employ a rigid front axle or a simple swing axle structure, which provides stability when traveling in a straight line but cannot allow for body roll when cornering. This results in poor cornering agility, a stiff handling experience, and an inability to efficiently corner using the balance of centrifugal force and gravitational torque like two-wheeled or tilting vehicles, reducing driving pleasure and cornering limits. Utility Model Content

[0003] This utility model addresses the shortcomings of existing technologies by providing an independent front suspension mechanism for a tiltable three-wheeled scooter. This mechanism is structurally stable, offers flexible handling, and enables tilting and turning.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an independent front suspension mechanism for a tiltable three-wheeled scooter. The scooter includes a fixed bracket with one end of a first upper swing arm and a second upper swing arm hinged to it, as well as one end of a first lower swing arm and a second lower swing arm. The other ends of the first upper swing arm and the first lower swing arm are rotatably connected to a first front wheel via a first connecting member, and the other ends of the second upper swing arm and the second lower swing arm are rotatably connected to a second front wheel via a second connecting member, forming a parallelogram structure to allow the scooter to tilt.

[0005] In the above scheme, preferably, both the first connecting member and the second connecting member include a wheel axle and connecting shafts at both ends, and the connecting shafts are rotatably connected to the swing arm.

[0006] In the above scheme, preferably, the fixed bracket is further provided with a locking component, which includes a locking disc and a locking insert. The locking disc is connected to the upper end of the fixed bracket via a rotating shaft, and the locking insert portion located on the fixed bracket wraps around and clamps the locking disc.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments: See below Figures 1-9 The independent front suspension mechanism of the tilting tricycle includes a fixed bracket 1, several swing arms, connectors, several front wheels, locking components, shock absorbers 18, and steering limit components.

[0025] The fixed bracket 1, as a supporting component, is generally fixedly connected to the bottom of the scooter. The scooter includes a steering rod 19 for controlling direction; therefore, the fixed bracket 1 is located below the steering rod 19. A handle is provided at the upper part of the steering rod 19 for the user to control the direction.

[0026] Furthermore, one end of the first upper swing arm 2 and the second upper swing arm 3, as well as one end of the first lower swing arm 4 and the second lower swing arm 5, are hinged to the fixed bracket 1. The swing arms are symmetrically arranged on both sides of the fixed bracket 1 to form independent suspension units.

[0027] The other end of the first upper swing arm 2 and the first lower swing arm 4 is rotatably provided with a first front wheel 8 via a first connecting member 6. Similarly, the other end of the second upper swing arm 3 and the second lower swing arm 5 is rotatably provided with a second front wheel 9 via a second connecting member 7.

[0028] Each of the connecting components specifically includes a wheel axle 10 and connecting shafts 11 at both ends thereof. The front wheel is rotatably connected to the wheel axle 10, allowing the front wheel to rotate freely around the wheel axle 10. Simultaneously, the connecting shafts 11 are rotatably connected to the corresponding swing arms, thereby forming a parallelogram structure between the first upper swing arm 2, the second upper swing arm 3, the first lower swing arm 4, the second lower swing arm 5, and the connecting components. This allows the two front wheels to move independently when the scooter turns, while the parallelogram mechanism enables overall tilting, thus adapting to curves and maintaining stability.

[0029] Furthermore, the scooter is also equipped with a locking component, which is mounted on the fixed bracket 1 and is used to rotate in the locking or unlocking tilting function to meet different usage scenarios.

[0030] Therefore, the locking assembly includes a locking disc 12 and a locking insert 13. The locking disc 12 is connected to the upper end of the fixed bracket 1 via a rotating shaft 14. In this embodiment, the locking disc 12 is positioned higher than the swing arm, and partially encloses and clamps the locking insert 13. The locking insert 13 is located below the rotating shaft 14. The locking insert 13 is used to lock the position of the locking disc 12.

[0031] Furthermore, the locking assembly also includes a locking cable 15 and a locking handle 16. The locking handle 16 is rotatably connected to the steering rod 19 and is positioned close to the handle for easy user operation. One end of the locking cable 15 is connected to the locking handle 16, and the other end is connected to the locking insert 13, used to control the clamping or releasing state of the locking insert 13.

[0032] When the locking handle 16 is activated, the locking insert 13 is driven by the locking cable 15 to clamp the locking disc 12, thereby preventing the lateral movement of the suspension mechanism; when released, the lateral movement is restored. At the same time, a tube 22 is provided between the steering rod 19 and the locking insert 13, and the locking cable 15 is provided through the tube 22 to protect the cable and ensure smooth operation.

[0033] The locking disc 12 is rotatably connected to the fixed arm 17. A shock absorber 18 is provided between the fixed arm 17 and the two sets of upper swing arms to absorb vibrations during driving and improve comfort. At the same time, the shock absorber 18 is located above the swing arms to save space.

[0034] A steering limiter 20 is provided at the bottom of the steering rod 19. Two sets of limit blocks 21 extend from the steering limiter 20 and are respectively located on both sides of the fixed bracket 1 to limit the steering angle and prevent over-steering. Two sets of steering tie rods 23 are also provided on the steering limiter 20, and the two steering tie rods 23 are respectively connected to the corresponding wheel axle 10. When the scooter tilts to one side, the steering rod 19 adapts to the change after the swing arm on one side swings. Therefore, the steering tie rods 23 are used to strengthen the strength between the swing arms after tilting.

[0035] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
