Description

Technical Field

[0001] This utility model relates to the field of transportation vehicles, specifically to a tricycle handlebar anti-sway mechanism and a tricycle. Background Technology

[0002] A tricycle is a three-wheeled vehicle widely used for transporting goods and personal travel. In modern technology, tricycles, such as three-wheeled motorcycles, experience lateral swaying of the front wheel due to uneven road surfaces, increasing the difficulty of control and causing riders to lose control of the handlebars, thus increasing the risk of traffic accidents. Furthermore, this driving style requires the driver to expend a significant amount of energy maintaining control of the handlebars, leading to driver fatigue over extended periods. Utility Model Content

[0003] The purpose of this utility model includes, for example, providing a tricycle handlebar anti-sway mechanism and a tricycle, which can provide active anti-sway damping for the handlebars, thereby reducing the difficulty of handlebar direction control and improving driving safety; at the same time, it can also reduce the labor intensity of the driver.

[0004] The embodiments of this utility model can be implemented as follows:

[0005] In a first aspect, this utility model provides a tricycle handlebar anti-sway mechanism, comprising a frame, handlebars, a steering shaft, a steering shaft tube, and a damping unit, wherein:

[0006] The handlebars are connected to the steering shaft, which is inserted into and rotatably engaged with the steering shaft tube; the steering shaft tube is mounted on the frame; the damping unit is connected to both the frame and the steering shaft to provide resistance that prevents the steering shaft from rotating relative to the steering shaft tube.

[0007] In an optional embodiment, the damping unit includes a transmission component and a damping component. The transmission component is connected to both the steering shaft and the damping component. The transmission component is used to convert the rotational motion of the steering shaft into the linear reciprocating motion of the damping component. The damping component is mounted on the vehicle frame.

[0008] Based on the above solution, the rotational motion of the steering shaft is switched to the reciprocating motion of the damping component through the transmission component. While the damping component provides damping, it does not affect the active steering of the handlebars, thus ensuring safe handling.

[0009] In an optional embodiment, the transmission assembly includes a transmission gear and a transmission rack. The transmission gear is mounted on the direction shaft, and the transmission rack is mounted on the damping assembly and meshes with the transmission gear. The transmission gear is used to rotate with the direction shaft and convert the rotational motion into the reciprocating motion of the transmission rack.

[0010] Based on the above scheme, the transmission component has a simple structure, is easy to assemble, and the transmission gear and transmission rack have high stability and are safe and reliable to use.

[0011] In an optional embodiment, a clearance hole is provided on the directional shaft tube, and the transmission gear and the transmission rack mesh at the clearance hole.

[0012] Based on the above solution, by setting clearance holes on the directional shaft tube, the internal space of the directional shaft tube can be reasonably utilized to realize the meshing of the transmission gear and the transmission rack. This eliminates the need to increase the axial length of the directional shaft to provide a position for installing the transmission gear, thus improving the compactness of the structure.

[0013] In an optional embodiment, the damping assembly includes a hydraulic cylinder, the transmission rack is connected to the piston rod of the hydraulic cylinder, and the cylinder body is mounted on the vehicle frame.

[0014] Based on the above scheme, the damping effect is achieved by using hydraulic oil in conjunction with the piston rod and cylinder. The structure is simple, easy to assemble, and has good damping effect and long service life.

[0015] In an optional embodiment, the damping assembly includes a damping sleeve and a damping rod. The damping sleeve is provided with a damping cavity, and the inner wall surface of the damping cavity and / or the outer surface of the damping rod are provided with an elastic damping layer. The damping rod is slidably inserted into the damping cavity. The transmission rack is connected to the damping rod, and the damping sleeve is fixed to the vehicle frame.

[0016] Based on the above scheme, the damping is provided by the friction generated when the damping rod and the damping sleeve slide relative to each other, and the damping effect is good.

[0017] In an optional embodiment, the elastic damping layer is configured as a rubber layer or a silicone layer.

[0018] Based on the above scheme, the selection of the elastic damping layer is flexible and the cost is low.

[0019] In an alternative embodiment, the transmission rack is detachably coupled to the damping assembly.

[0020] Based on the above solution, the transmission rack can be replaced independently when it wears out, reducing operating costs.

[0021] In an optional embodiment, the directional shaft and the directional shaft tube are rotatably coupled via bearings.

[0022] Based on the above solution, the rotation of the steering shaft and steering shaft tube is flexible, with low friction, not easy to wear, and long service life.

[0023] Secondly, this utility model provides a tricycle, the tricycle comprising:

[0024] The anti-sway mechanism for the handlebars of the tricycle as described in any of the foregoing embodiments.

[0025] The beneficial effects of this utility model embodiment include, for example:

[0026] In summary, the tricycle handlebar anti-sway mechanism provided in this embodiment ensures that during driving, the driver maintains stability by gripping the handlebars. When encountering uneven road conditions, the front wheel experiences bumps, which are transmitted to the handlebars via the steering shaft, causing a rotational force on the handlebars. Due to the design of the damping unit, this force, when transmitted to the steering shaft, is relayed to the damping unit via the transmission shaft. The damping unit provides resistance to the rotation of the steering shaft, reducing the torque transmitted to the handlebars and decreasing the force required for the driver to stabilize them. This makes it easier to control the handlebars, reducing driver fatigue and improving safety. When the driver needs to turn, force is applied to the handlebars. Due to the handlebars' structural design, they are flexible and can actively overcome the damping applied to the steering shaft by the damping unit. The damping unit does not affect the steering of the handlebars, ensuring safe and reliable steering operation. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0036] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0037] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0038] In the existing technology, when a tricycle is traveling on a bumpy road, the front wheel 001 is subjected to external force and twists. The twisting force is transmitted to the handlebars through the shaft, which requires the driver to exert force on the handlebars to overcome the twisting force. This increases the driver's labor intensity, makes it easy to drive while fatigued, and poses a safety hazard.

[0039] In view of this, the designers have provided a tricycle handlebar anti-sway mechanism, which can provide damping to prevent the rotation of the steering shaft 300, thereby reducing the torsional force on the handlebar 200, reducing the driver's labor intensity, making it easier for the driver to stabilize the direction of the handlebar 200, reducing fatigue driving, and ensuring safety and reliability.

[0040] Please refer to Figure 1 and Figure 2 This embodiment provides a tricycle handlebar anti-sway mechanism, which includes a frame 100, handlebars 200, steering shaft 300, steering shaft tube 400, and damping unit 500. The handlebars 200 are connected to the steering shaft 300, and the steering shaft 300 is inserted into the steering shaft tube 400 and rotatably engaged with the steering shaft tube 400. The steering shaft tube 400 is mounted on the frame 100. The damping unit 500 is connected to both the frame 100 and the steering shaft 300, and is used to provide resistance that prevents the steering shaft 300 from rotating relative to the steering shaft tube 400.

[0041] As described above, the tricycle handlebar anti-sway mechanism provided in this embodiment works as follows:

[0042] During the operation of the tricycle, the driver holds the handlebars 200 to stabilize their direction. When encountering uneven road conditions, the front wheel experiences bumps, which are transmitted to the handlebars 200 via the steering shaft 300. This causes the handlebars 200 to experience a rotational force. Due to the design of the damping unit 500, the force driving the handlebars 200 to rotate is transmitted to the damping unit 500 via the drive shaft when it reaches the steering shaft 300. The damping unit 500 provides damping to resist the rotation of the steering shaft 300, thus reducing the torque transmitted to the handlebars 200. This reduces the force required for the driver to stabilize the handlebars 200, making it easier to control their direction, reducing the driver's workload, and improving safety. When the driver needs to turn, force is applied to the handlebar 200. Due to the structural design of the handlebar 200, the steering is flexible and can actively overcome the damping applied to the steering shaft 300 by the damping unit 500. The damping unit 500 will not affect the steering of the handlebar 200, and the steering operation of the handlebar 200 is safe and reliable.

[0043] The following embodiments illustrate the details of the anti-sway mechanism for the handlebars of the tricycle of this application by way of example.

[0044] Please refer to Figure 1In this embodiment, optionally, the tricycle handlebar anti-sway mechanism includes a frame 100, handlebars 200, a steering shaft 300, a steering shaft tube 400, a damping unit 500, and a bearing 600. The handlebars 200 are connected to the steering shaft 300, which is inserted into the steering shaft tube 400 and rotatably engaged with it via the bearing 600. The steering shaft tube 400 is mounted on the frame 100. The damping unit 500 is connected to both the frame 100 and the steering shaft 300, providing resistance to prevent the steering shaft 300 from rotating relative to the steering shaft tube 400.

[0045] In this embodiment, optionally, the steering shaft tube 400 can be set as a metal round tube. One end of the steering shaft tube 400 can be welded and fixed to the frame 100 or fixed by a screw connection. Both ends of the steering shaft tube 400 are open. The steering shaft 300 passes through one end of the steering shaft tube 400 and exits from the other end of the steering shaft tube 400. The steering shaft 300 can be connected to the front fork of the tricycle, thereby controlling the steering of the front wheel 001 through the handlebars 200.

[0046] Please refer to Figure 2 Optionally, a clearance hole 410 is provided on the circumferential tube wall of the steering shaft tube 400. The clearance hole 410 is located between the two ends of the steering shaft tube 400, and the distance between the clearance hole 410 and the frame 100 is greater than the distance between the clearance hole 410 and the handlebar 200. This facilitates the connection of the steering shaft 300 and the damping unit 500 at the clearance hole 410.

[0047] It should be understood that, since the relief hole 410 is provided on the directional shaft tube 400, the internal space of the directional shaft tube 400 is reasonably utilized to realize the meshing of the transmission gear 510 and the transmission rack 520, so that it is not necessary to increase the axial length of the directional shaft 300 to provide a position for installing the transmission gear 510, thereby improving the compactness of the structure.

[0048] Please refer to Figure 1 and Figure 2 In this embodiment, optionally, the damping unit 500 includes a transmission component and a damping component. The transmission component is connected to both the steering shaft 300 and the damping component, and is used to convert the rotational motion of the steering shaft 300 into the linear reciprocating motion of the damping component. The damping component is mounted on the frame 100. By switching the rotational motion of the steering shaft 300 to the reciprocating motion of the damping component through the transmission component, the active steering of the handlebars 200 is not affected while the damping component provides damping, ensuring safe handling.

[0049] Optionally, the transmission assembly includes a transmission gear 510 and a transmission rack 520. The transmission gear 510 is sleeved on the outside of the steering shaft 300 and fixedly fitted. The transmission rack 520 is mounted on the damping assembly and meshes with the transmission gear 510. A portion of the transmission rack 520 passes through a clearance hole 410, while a portion of the transmission gear 510 is exposed at the clearance hole 410. The transmission rack 520 meshes with the transmission gear 510 at the clearance hole 410. The transmission gear 510 rotates with the steering shaft 300 and converts the rotational motion into the reciprocating motion of the transmission rack 520. That is, when the steering shaft 300 is subjected to torque, it can drive the transmission gear 510 to rotate, thereby driving the transmission rack 520 to reciprocate linearly, which in turn drives the damping assembly to move. The damping assembly absorbs torque or reduces the torque transmitted to the handlebar 200.

[0050] Force is transmitted through the cooperation of transmission gear 510 and transmission rack 520, resulting in a stable structure.

[0051] In one embodiment, optionally, the damping assembly includes a hydraulic cylinder, with a drive rack 520 connected to a piston rod 530 of the hydraulic cylinder. The cylinder body 540 can be bolted to the frame 100, and the piston rod 530 slidably engages with the hydraulic cylinder, providing damping through the cooperation of the piston rod 530 and the cylinder body 540. In this case, the drive rack 520 can be detachably connected to the piston rod 530 via bolts or the like.

[0052] In another embodiment, optionally, the damping assembly includes a damping sleeve and a damping rod. The damping sleeve has a damping cavity, and the inner wall surface of the damping cavity and / or the outer surface of the damping rod are provided with an elastic damping layer. The damping rod is slidably inserted into the damping cavity. A transmission rack 520 is connected to the damping rod, and the damping sleeve is fixed to the frame 100. When the damping rod slides relative to the damping sleeve, it needs to overcome the damping provided by the elastic damping layer, thereby absorbing the external force transmitted through the transmission rack 520. In this case, the transmission rack 520 can be detachably connected to the damping rod by bolts or the like.

[0053] It should be understood that the elastic damping layer is set as a rubber layer or a silicone layer, and the rubber layer or silicone layer can be fixed to the damping sleeve or damping rod by means of bonding, which is a simple and reliable fixing method.

[0054] It should be noted that the transmission rack 520 is detachably connected to the piston rod 530 or the damping rod. When the transmission rack needs to be replaced, it can be removed from the piston rod 530 or the damping rod, which is convenient to operate and low in cost.

[0055] The anti-sway mechanism for the tricycle handlebars provided in this embodiment, due to the design of the damping unit 500, transmits external force to the steering shaft 300 when the front wheel 001 is vibrated and deflected on bumpy roads. Then, it is transmitted to the transmission rack 520 through the transmission gear 510. The damping component reduces or absorbs the external force, reduces or even eliminates the external force at the handlebars 200, which helps the driver stabilize the direction of the handlebars 200, reduces the workload, and improves safety.

[0056] This embodiment also provides a tricycle, which includes a tricycle handle anti-sway mechanism, based at least on the advantages of easy operation and high safety.

[0057] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
