Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, and in particular to a vehicle steering wheel structure. Background Technology

[0002] Motorcycles, bicycles, and mobility scooters are widely used due to their small size, ease of driving, and low maintenance costs. However, existing vehicle handlebars, due to their relatively flexible design, tend to wobble during straight-line travel, causing the vehicle to deviate from its straight-line trajectory. This necessitates frequent steering adjustments by the rider to maintain a straight-line position, increasing the burden of control and significantly depleting the rider's energy. Current technology lacks an effective automatic return-to-center mechanism to stabilize the vehicle's direction, making it difficult to achieve automatic reset after turning. This fails to effectively reduce the rider's workload during extended straight-line riding, and the inability to automatically return to center after turns necessitates manual steering, causing inconvenience. Therefore, designing a vehicle handlebar with an automatic return-to-center function is a pressing issue that needs to be addressed. Summary of the Invention

[0003] The purpose of this utility model is to provide a vehicle steering wheel structure and vehicle, which aims to solve problems such as the steering wheel not being able to automatically return to center when turning.

[0004] To solve the above-mentioned technical problems, this utility model provides a vehicle steering wheel structure, including: a frame, a front fork mounted on the front end of the frame, a steer tube and a steering wheel on the front fork; a spring return mechanism, one end of which is connected to the frame and the other end of which is connected to the steer tube; the spring return mechanism can provide a spring force to keep the steer tube in a centered state so that the vehicle can keep moving straight.

[0005] Furthermore, the spring reset mechanism includes: an air spring, initially arranged parallel to the rudder tube; and ball joints, disposed at both ends of the air spring, for connecting the air spring to the rudder tube and the vehicle frame.

[0006] Furthermore, the spring reset mechanism also includes: a first link connecting the upper end of the air spring to the rudder tube via a ball joint; and a second link connecting the lower end of the air spring to the vehicle frame via a ball joint; both the first link and the second link are arranged perpendicular to the air spring.

[0007] Furthermore, the spring reset mechanism also includes: a locking nut, which is respectively disposed between the first connecting rod and the rudder tube and between the second connecting rod and the vehicle frame.

[0008] Furthermore, the spring reset mechanism also includes a connecting block for connecting the first connecting rod and the rudder tube, so as to facilitate the disassembly of the spring reset mechanism.

[0009] Furthermore, the connecting block includes a clamping end and a connecting end; the clamping end is used to clamp the rudder tube; the connecting end is used to connect the first connecting rod.

[0010] Furthermore, the connecting end protrudes above the clamping end.

[0011] Furthermore, the vehicle steering structure also includes: a sleeve, which is rotatably sleeved outside the steering tube, and the sleeve is integral with the vehicle frame; the second connecting rod connects the lower end of the air spring to the sleeve.

[0012] Furthermore, the protruding end and the clamping end are detachably fixedly connected. Specifically, the protruding end and the clamping end are connected by a threaded connection. This connection allows for easy maintenance by simply separating the clamping end from the protruding end without disassembling it when the air spring needs to be replaced.

[0013] Furthermore, the vehicle is a tricycle; in some embodiments, the vehicle may also be a two-wheeled vehicle, such as a bicycle, electric vehicle, etc.

[0014] Usage State 1: Vehicle turning left. The steering wheel is turned counterclockwise. At this time, the steering tube drives the first link to turn counterclockwise along with the steering wheel. The upper end of the first link rotates clockwise around the ball joint at the lower end of the first link. At the same time, the air spring is stretched, generating restoring force. After the vehicle completes the left turn, the force on the steering wheel is released, and the air spring contracts, causing the upper end of the first link to rotate counterclockwise around the ball joint at the lower end of the first link, which in turn drives the steering wheel back to the straight-ahead state.

[0015] Usage State 2: Vehicle Turning Right. When the steering wheel is turned clockwise, the steering tube drives the first link to follow the steering wheel's clockwise rotation. The upper end of the first link rotates counterclockwise around the ball joint at the lower end of the first link. At the same time, the air spring is stretched, generating restoring force. After the vehicle completes the right turn, the force on the steering wheel is released, and the air spring contracts, causing the upper end of the first link to rotate clockwise around the ball joint at the lower end of the first link, leading the steering wheel back to the straight-ahead state.

[0016] Usage State 3: Vehicle traveling straight. The vehicle is traveling straight, but the bumps cause the steering wheel to swing from side to side. At this time, the air spring is always in a stretched state. Therefore, the air spring can always generate restoring force to reduce the swing amplitude of the steering wheel caused by the bumps, so that the vehicle can keep traveling straight as much as possible.

[0017] This utility model also provides a vehicle, including the vehicle steering wheel structure as described in the above embodiments.

[0018] Implementing the embodiments of this utility model will have the following beneficial effects: By setting a spring return mechanism between the steering tube and the frame, the steering wheel of the vehicle can automatically return to center after turning. The spring return mechanism is simple in structure, highly stable, and low in cost, thus improving the ease of vehicle operation. Attached Figure Description

Preferred embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0025] Motorcycles, bicycles, and mobility scooters are widely used due to their small size, ease of driving, and low maintenance costs. However, existing vehicle handlebars, due to their relatively flexible design, tend to wobble during straight-line travel, causing the vehicle to deviate from its straight-line trajectory. This necessitates frequent steering adjustments by the rider to maintain a straight-line position, increasing the burden of control and significantly depleting the rider's energy. Current technology lacks an effective automatic return-to-center mechanism to stabilize the vehicle's direction, making it difficult to achieve automatic reset after turning. This fails to effectively reduce the rider's workload during extended straight-line riding, and the inability to automatically return to center after turns necessitates manual steering, causing inconvenience. Therefore, designing a vehicle handlebar with an automatic return-to-center function is a pressing issue that needs to be addressed.

[0026] This utility model provides a vehicle steering wheel structure and a vehicle. The vehicle steering wheel structure includes a frame, a steering wheel, and a steering tube. By setting a spring return mechanism between the steering tube and the frame, the vehicle steering wheel can automatically return to center after turning. The spring return mechanism is simple in structure, highly stable, and low in cost, thus improving the ease of vehicle operation.

[0027] Combination Figures 1 to 5As shown, this embodiment of the present disclosure provides a vehicle steering wheel structure 100, including a frame 110 and a spring return mechanism 150. A front fork 120 is mounted on the front end of the frame 110, and the front fork 120 is connected to the wheel for controlling wheel steering. The front fork 120 is provided with a steerer tube 130 and a steering wheel 140. The steerer tube 130 is fixedly connected to the top of the front fork 120. Rotation of the steerer tube 130 drives the front fork 120 to rotate, which in turn drives the wheel to rotate. One end of the spring return mechanism 150 is connected to the frame 110. The frame 110 is stationary relative to the wheel, and the other end of the spring return mechanism 150 is connected to the frame 110 and does not rotate with the wheel. The other end of the spring return mechanism 150 is connected to the steer tube 130, which is connected to the steering wheel 140. Rotation of the steering wheel 140 drives the steerer tube 130 to rotate, which in turn drives the other end of the spring return mechanism 150 to rotate. One end of the spring reset mechanism 150 remains stationary while the other end rotates with the rudder tube 130, causing the spring in the spring reset mechanism 150 to be in a stretched state. The restoring force of the spring in the spring reset mechanism 150 can provide the elastic force to keep the rudder tube 130 in the centered state so that the vehicle 200 keeps moving straight.

[0028] Combination Figure 2 and Figure 4 As shown, in some embodiments, the spring return mechanism 150 includes an air spring 151 and a ball joint 152. The air spring 151 is initially positioned parallel to the steering tube 130. For example, when the vehicle 200 is traveling straight, the steering tube 130 is in a vertical position, and the extension direction of the air spring 151 is vertical. The ball joint 152 is located at both ends of the air spring 151, connecting the air spring 151 to the steering tube 130 and the frame 110. That is, the upper end of the air spring 151 is connected to the steering tube 130 via the ball joint 152 to achieve a rotatable connection with the steering tube 130, and the lower end of the air spring 151 is connected to the frame 110 to achieve a rotatable connection with the frame 110. When the steering wheel 140 rotates, it drives the upper end of the air spring 151 to rotate and move while being extended. Since the lower end of the air spring 151 is connected to the frame 110 via the ball joint 152, the air spring 151 tilts as a whole in the direction of rotation of the steering wheel 140. Under the restoring force of the air spring 151, the air spring 151 is pulled from the inclined stretching state back to the vertical contraction state, and at the same time the faucet 140 is pulled back to its original position.

[0029] Combination Figure 2 , Figure 3 and Figure 4As shown, in some embodiments, the spring return mechanism 150 further includes a first link 153 and a second link 154. The first link 153 connects the upper end of the air spring 151 to the rudder tube 130 via a ball joint 152. One end of the first link 153 is detachably connected to the rudder tube 130, and the other end is fixedly connected to the ball joint 152. For example, one end of the first link 153 is provided with an external thread, the rudder tube 130 is designed with a matching internal thread, the other end of the first link 153 is provided with a spherical surface, and the upper end of the air spring 151 is provided with an inner spherical surface, which, together with the spherical surface of the first link 153, forms the ball joint 152. The second link 154 connects the lower end of the air spring 151 to the frame 110 via the ball joint 152. The second link 154 has the same structure as the first link 153. Both the first link 153 and the second link 154 are arranged perpendicular to the air spring 151. In the initial state, the air spring 151 is vertical, and the first link 153 and the second link 154 are both horizontal, so that after a period of use, the condition of the air spring 151 can be preliminarily judged by observation, so as to carry out regular maintenance and replacement.

[0030] Combination Figure 2 and Figure 4 As shown, in some embodiments, the spring return mechanism 150 further includes a locking nut 155. The locking nuts 155 are respectively disposed between the first connecting rod 153 and the steer tube 130, and between the second connecting rod 154 and the frame 110. The locking nuts 155 have internal threads, and one end of the first connecting rod 153 has an external thread, which first engages with the adjusting nut and then is screwed into the corresponding internal thread on the steer tube 130. One end of the second connecting rod 154 has an external thread, which first engages with the locking nut 155 and then is screwed into the corresponding internal thread on the frame 110. The locking nut 155 of the first connecting rod 153 and the internal thread on the steer tube 130 together form a double nut to lock the first connecting rod 153 and the steer tube 130. The locking nut 155 of the second connecting rod 154 and the corresponding internal thread on the frame 110 together form a double nut to lock the second connecting rod 154 and the frame 110. Meanwhile, during installation, the locking nut 155 can also adjust the length of the first connecting rod and the second connecting rod 154.

[0031] Combination Figures 1 to 4 As shown, in some embodiments, the spring return mechanism 150 further includes a connecting block 156. The connecting block 156 is used to connect the first connecting rod 153 and the rudder tube 130 to facilitate the disassembly of the spring return mechanism 150. The upper end of the first connecting rod 153 is connected to one end of the connecting block 156 by a threaded connection, that is, one end of the connecting block 156 is provided with an internal thread that mates with the first connecting rod 153. The other end of the connecting block 156 is fixedly connected to the rudder tube 130.

[0032] Combination Figures 1 to 4As shown, in some embodiments, the connecting block 156 includes a clamping end 1561 and a connecting end 1562. The clamping end 1561 is used to clamp the rudder tube 130, and the connecting end 1562 is used to connect the first connecting rod 153. The clamping end 1561 includes two mating clamping edges that clamp the rudder tube 130 relative to each other. The two clamping edges are connected by bolts to clamp the rudder tube 130. The connecting end 1562 is fixedly integrated with the clamping end 1561. The connecting end 1562 is provided with an internal thread corresponding to the first connecting rod 153. The first connecting rod 153 is fixedly connected to the connecting end 1562 by screwing into the internal thread.

[0033] Combination Figure 2 As shown, in some embodiments, the connecting end 1562 protrudes above the clamping end 1561. A protruding plate is provided above the clamping end 1561, and internal threads are machined on the protruding plate to maximize the connection strength.

[0034] In some embodiments, the protrusion and the clamping end 1561 are detachably fixedly connected. Specifically, the protrusion and the clamping end 1561 are connected by a threaded connection. This connection allows for easy maintenance by separating the clamping end 1561 directly from the protrusion without disassembling the air spring 151 when it needs to be replaced.

[0035] Combination Figure 1 , Figure 3 and Figure 5 As shown, in some embodiments, the vehicle steering structure 100 further includes a sleeve 160. The sleeve 160 is integral with the frame 110. The sleeve 160 is rotatably fitted over the steering tube 130, which is rotatable within the sleeve 160. A second link 154 connects the lower end of the air spring 151 to the sleeve 160. The sleeve 160 is integral with the frame 110 to keep the lower end of the air spring 151 stationary.

[0036] Combination Figures 1 to 5 As shown, this utility model also provides a vehicle 200, including the vehicle handle structure 100 as described in the above embodiments.

[0037] In some embodiments, such as Figure 1 to, Figure 3 and Figure 5 As shown, vehicle 200 is a tricycle; in some embodiments, vehicle 200 may also be a two-wheeled vehicle, such as a bicycle, electric vehicle, etc.

[0038] For example, when vehicle 200 turns left, the steering wheel 140 rotates counterclockwise. At this time, the steering tube 130 drives the first link 153 to rotate counterclockwise along with the steering wheel 140. The upper end of the first link 153 rotates clockwise around the ball joint 152 at the lower end of the first link 153. At the same time, the air spring 151 is stretched, generating restoring force. After vehicle 200 completes the left turn, the force on the steering wheel 140 to turn left is removed, and the air spring 151 contracts, causing the upper end of the first link 153 to rotate counterclockwise around the ball joint 152 at the lower end of the first link 153, driving the steering wheel 140 back to the straight-going state.

[0039] Similarly, when vehicle 200 turns right, the steering wheel 140 rotates clockwise. At this time, the steering tube 130 drives the first link 153 to rotate clockwise along with the steering wheel 140. The upper end of the first link 153 rotates counterclockwise around the ball joint 152 at the lower end of the first link 153. At the same time, the air spring 151 is stretched, generating restoring force. After vehicle 200 completes the right turn, the force on the steering wheel 140 to turn right is removed, and the air spring 151 contracts, causing the upper end of the first link 153 to rotate clockwise around the ball joint 152 at the lower end of the first link 153, driving the steering wheel 140 back to the straight-going state.

[0040] When the vehicle 200 is bumped and the handlebars 140 swing from side to side, the air spring 151 is always in a stretched state. Therefore, the air spring 151 can always generate restoring force to reduce the swing amplitude of the handlebars 140 caused by the bumps, so that the vehicle 200 can keep the vehicle as straight as possible.
