Description

Technical Field

[0001] This utility model relates to the field of anti-skid wheel technology, specifically an anti-skid wheel. Background Technology

[0002] Traditional wheel slip prevention measures rely primarily on driver input, such as timely deceleration or gear shifting, to prevent wheel slippage. However, this method demands a high level of driver skill and still carries the risk of accidents under extreme conditions.

[0003] Especially in adverse weather conditions such as wet, slippery, icy, or snowy conditions, the excessively slippery wheels of vehicles can lead to loss of control and frequent traffic accidents. This increases the burden on drivers and enhances driving comfort and confidence.

[0004] On complex road surfaces, such as mountainous areas, deserts, snowy or muddy terrain, wheels cannot adapt to different surface conditions. Variable diameter wheels cannot adaptively adjust their diameter to provide optimal traction and stability on different road surfaces. Furthermore, driving large-diameter wheels on flat roads consumes a significant amount of energy, resulting in energy waste. Summary of the Invention

[0005] In view of the shortcomings of the prior art and in order to solve the problems mentioned in the background art, the technical problem to be solved by the present invention is to provide an anti-skid wheel that can adjust the wheel diameter at any time according to the vehicle type and road conditions, and can generate friction to effectively grip the ground and save energy.

[0006] The technical problem to be solved by this utility model is achieved through the following technical solution: an anti-skid wheel includes a wheel body. A plurality of radial grooves are provided along the center on one side of the wheel body. Each groove has a strip-shaped notch on its surface. Each groove contains a synchronously extending and retracting spoke. The end of each spoke has an arc-shaped wheel body. The outer contour of the arc-shaped wheel body forms a gap circle larger than the diameter of the wheel body. Resistance teeth are provided on the outer arc surface of the arc-shaped wheel body. These resistance teeth effectively cope with complex road conditions when the wheel is in motion, increasing the friction between the wheel and the ground. When encountering rough road surfaces, the resistance teeth maintain the stability of the wheel, reducing the risk of slippage or loss of control. A gap exists between two arc-shaped wheel bodies, which increases friction during movement.

[0007] The wheel body is equipped with a drive mechanism that drives the spokes to extend and retract synchronously. The drive mechanism includes a large gear located at the center of a circle on one side of the groove. The large gear meshes with a small gear. The small gear rotates, driving the large gear to rotate. The large gear is equipped with arc-shaped guide holes that correspond to the groove. The arc-shaped guide holes rotate in the same direction and are evenly distributed circumferentially. A positioning guide post is provided in the arc-shaped guide hole. The positioning guide post is perpendicularly hinged to the end of the spoke. The positioning guide post reciprocates along the length of the strip notch, driving the spokes to extend and retract along the groove.

[0008] The spokes on the wheel body can be adjusted according to road conditions via a synchronous extension and retraction mechanism. The spokes within the grooves can extend or retract as needed, increasing the wheel's contact area with the ground and improving traction on different road surfaces. On wet, slippery, icy, or snowy surfaces, the spokes can extend to increase friction and improve grip; while on flat, dry surfaces, the spokes can retract to reduce friction and improve driving efficiency.

[0009] Different vehicle models are equipped with wheels of different diameters. The diameter of the wheels can be adjusted in real time according to driving speed, load and road conditions. On complex road surfaces, such as mountainous areas, deserts, snowy or muddy terrain, variable diameter wheels can adjust their diameter under different road conditions to help vehicles provide the best traction and stability on different road surfaces.

[0010] As a further embodiment of this utility model, the pinion is disposed at the edge of the wheel body, and a mounting hole is provided on the wheel body corresponding to the center hole of the pinion. A rotary motor is provided on the wheel body on the other side of the pinion, and a power supply and a controller are provided on the side of the rotary motor. The power supply and the rotary motor are electrically connected, and the controller and the rotary motor are communicatively connected. The rotating shaft of the rotary motor passes through the mounting hole and extends into the center hole of the pinion. The rotating shaft is fitted with the keyway of the center hole, and a bearing is provided in the mounting hole. The inner ring of the bearing is interference-fitted with the rotating shaft.

[0011] A pinion gear is combined with a rotary motor, and the rotary motor's rotating shaft drives the pinion gear to rotate, thus transmitting power. This gear transmission method ensures efficient and smooth power transmission while reducing friction and energy loss, improving overall drive efficiency. The controller communicates with the rotary motor to achieve precise motor control, including adjusting speed and direction. Adjustments can be made to meet different needs, providing greater operability and flexibility.

[0012] As a further embodiment of this invention, a mounting ring is provided at the center of the wheel body on one side of the rotary motor, and the mounting ring is fixedly connected to the end of the axle. The mounting ring is synchronously connected to the axle through a mounting bearing to ensure that the axle and the wheel move synchronously.

[0013] As a further embodiment of this invention, a fixing plate is provided on one side of the rotary motor, and the fixing plate has positioning holes. The rotary motor and the fixing plate are fixedly connected to the positioning holes by bolts. This effectively reduces the shaking or offset of the rotary motor during operation, improves the stability of the motor during operation, and enhances the overall reliability of the system.

[0014] As a further embodiment of this invention, the spoke end is provided with a hinge hole, and the positioning guide post is concentrically arranged with the hinge hole. An upper limit end plate and a lower limit end plate are respectively provided at both ends of the positioning guide post. The diameter of the lower limit end plate is smaller than that of the slide groove, and the lower limit end plate slides along the slide groove. The upper limit end plate slides with the upper surface of the large gear. The lower limit end plate's smaller diameter and ability to slide along the slide groove ensure an effective movement path for the spoke. The sliding engagement of the upper and lower limit end plates effectively controls the range of movement of the spoke and the assembly range with the large gear.

[0015] As a further embodiment of this invention, the width of the strip-shaped notch is smaller than the width of the groove, and the opening length of the strip-shaped notch is smaller than the length of the groove. This limits the displacement of the positioning guide post in both the vertical and horizontal directions. The dimensional matching between the notch and the groove allows the component to slide smoothly within the groove, while simultaneously limiting the risk of component detachment and ensuring the movement trajectory of the spokes.

[0016] As a further embodiment of this invention, the resistance teeth include concave and convex teeth arranged along the arc length of the arc-shaped wheel body, which make frictional contact with the ground. The concave and convex structure of the resistance teeth provides more friction surface when in contact with the ground, significantly increasing the friction and gripping force between the wheel body and the ground. This results in better grip, reduces the risk of wheel slippage, and effectively improves the traction and stability of vehicles or mechanical equipment.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: This anti-skid wheel includes a wheel body. A plurality of radial grooves are provided along the center on one side of the wheel body. Each groove has a strip-shaped notch on its surface. Each groove contains a synchronously extending and retracting spoke. The end of each spoke has an arc-shaped wheel body. The outer contour of the arc-shaped wheel body forms a gap circle larger than the diameter of the wheel body. Resistance teeth are provided on the outer arc surface of the arc-shaped wheel body. These resistance teeth effectively cope with complex road conditions when the wheel is in motion, increasing the friction between the wheel and the ground. When encountering rough road surfaces, the resistance teeth maintain the stability of the wheel, reducing the risk of slippage or loss of control. A gap exists between two arc-shaped wheel bodies, which increases friction during movement.

[0018] The wheel body is equipped with a drive mechanism that drives the spokes to extend and retract synchronously. The drive mechanism includes a large gear located at the center of a circle on one side of the groove. The large gear meshes with a small gear. The small gear rotates, driving the large gear to rotate. The large gear is equipped with arc-shaped guide holes that correspond to the groove. The arc-shaped guide holes rotate in the same direction and are evenly distributed circumferentially. A positioning guide post is provided in the arc-shaped guide hole. The positioning guide post is perpendicularly hinged to the end of the spoke. The positioning guide post reciprocates along the length of the strip notch, driving the spokes to extend and retract along the groove.

[0019] The spokes on the wheel body can be adjusted according to road conditions via a synchronous extension and retraction mechanism. The spokes within the grooves can extend or retract as needed, increasing the wheel's contact area with the ground and improving traction on different road surfaces. On wet, slippery, icy, or snowy surfaces, the spokes can extend to increase friction and improve grip; while on flat, dry surfaces, the spokes can retract to reduce friction and improve driving efficiency.

[0020] Different vehicle models are equipped with wheels of different diameters. The diameter of the wheels can be adjusted in real time according to driving speed, load and road conditions. On complex road surfaces, such as mountainous areas, deserts, snowy or muddy terrain, variable diameter wheels can adjust their diameter under different road conditions to help vehicles provide the best traction and stability on different road surfaces.

[0035] Example 1

[0036] As attached Figure 1 - Appendix Figure 8As shown, an anti-skid wheel includes a wheel body 1. A plurality of radial grooves 101 are provided on one side of the wheel body along the center. A strip-shaped notch 111 is provided on the surface of the wheel body where the groove is located. The width of the strip-shaped notch is smaller than the width of the groove, and the opening length of the strip-shaped notch is smaller than the length of the groove.

[0037] Each groove is equipped with synchronously extending spokes 3. The wheel body and spokes are made of materials with good flexibility, high hardness and high strength, such as high-strength stainless steel.

[0038] The spoke ends are provided with an arc-shaped wheel body 2. The outer contour of the arc-shaped wheel body forms a gap circle larger than the diameter of the wheel body. The outer arc surface of the arc-shaped wheel body is provided with resistance teeth 201. The resistance teeth include concave and convex teeth provided along the arc length direction of the arc-shaped wheel body. The concave and convex teeth make frictional contact with the ground. The resistance teeth can also be set to other tooth shapes that can improve resistance.

[0039] There is an assembly gap between two adjacent arc-shaped wheels. When the resistance teeth contact the ground, the wheel body rotates, and the gap circle formed by the arc-shaped wheels moves along the trajectory on the ground. The assembly gap plays the same resistance role as the concave and convex teeth, improving the grip and friction between the arc-shaped wheels and the ground, and ensuring that the wheels can travel stably on complex road surfaces.

[0040] The wheel body has a mounting ring 7 at its center on one side of the rotary motor, and the mounting ring is fixedly connected to the end of the axle. The mounting ring has bolt holes, and the axle end has assembly holes corresponding to the bolt holes on the mounting ring, which are tightened by passing bolts through them.

[0041] The wheel body is equipped with a drive mechanism that drives the spokes to extend and retract synchronously. The drive mechanism includes a large gear 5 located at the center of one side of the slide groove, and a small gear 4 meshing with the large gear. The small gear rotates and drives the large gear to rotate. The small gear is located at the edge of the wheel body. The wheel body has a mounting hole corresponding to the center hole of the small gear. A rotary motor 8 is located on the other side of the wheel body on the small gear. A fixing plate 801 is located on one side of the rotary motor. The fixing plate has a positioning hole. The rotary motor and the fixing plate are fixedly connected by bolts to the positioning hole.

[0042] The rotating motor is equipped with a power supply 9 and a controller 10. The power supply and the rotating motor are electrically connected, and the controller and the rotating motor are communicatively connected. The rotating shaft of the rotating motor passes through the mounting hole and extends into the center hole of the pinion. The rotating shaft is fitted with the keyway of the center hole. A bearing is installed in the mounting hole, and the inner ring of the bearing is interference-fitted with the rotating shaft.

[0043] When a vehicle is driving in mountainous, desert, icy, or muddy terrain, large-diameter wheels can improve the vehicle's traction efficiency in harsh road conditions, reduce tire slippage, and the traction force generated by large-diameter wheels reduces vehicle slippage in sandy, snowy, and other places, thus improving the vehicle's traction efficiency.

[0044] The large gear is provided with arc-shaped guide holes 501 respectively corresponding to the slide groove. The arc-shaped guide holes are rotated in the same direction and are evenly distributed in the circumference. A positioning guide post 6 is provided in the arc-shaped guide hole. The positioning guide post 6 is perpendicularly hinged to the end of the spoke 3. The end of the spoke is provided with a hinge hole 301. The positioning guide post and the hinge hole are concentrically arranged. An upper limit end plate and a lower limit end plate are respectively provided at both ends of the positioning guide post. The diameter of the lower limit end plate is smaller than that of the slide groove. The lower limit end plate slides along the slide groove. The upper limit end plate slides with the surface of the large gear.

[0045] When it is necessary to increase the diameter of the clearance circle formed by the outer contour of the arc-shaped wheel, the rotary motor 8 is started. The rotary motor moves forward, driving the small gear to rotate forward, which in turn drives the large gear to rotate forward. The positioning post slides along the arc-shaped guide hole in the direction of increasing diameter. At the same time, the positioning post is limited by the slide groove in the straight direction. The positioning guide post moves along the length of the strip notch in the direction of the opening, driving the spokes to extend along the slide groove. The rotation of the large gear drives all the positioning guide posts to move synchronously in the same direction, thus forming a large-diameter clearance circle.

[0046] When the clearance circle diameter reaches the set diameter, the rotary motor is turned off. All spokes extend to the same length, and the circumference of the arc-shaped wheel forms a circular outer arc surface that rolls on the ground. The outer arc surface has resistance teeth that provide gripping and friction during movement, allowing the wheel to roll more smoothly and prevent slippage.

[0047] Example 2

[0048] When a vehicle travels on a flat surface, small-diameter wheels can reduce driving force and save energy, thus ensuring the vehicle's traction efficiency with low energy consumption.

[0049] When the diameter of the gap circle formed by the outer contour of the arc-shaped wheel needs to be reduced, the rotary motor 8 is started. The rotary motor moves in the reverse direction, driving the small gear 4 to rotate in the reverse direction, which in turn drives the large gear 5 to rotate in the reverse direction. The positioning post slides along the arc-shaped guide hole in the direction of decreasing diameter. At the same time, the positioning post is limited by the slide groove 101 in the straight direction. The positioning guide post moves away from the opening along the length of the strip notch 111, driving the spokes 3 to retract along the slide groove 101. The rotation of the large gear drives all the positioning guide posts 6 to move synchronously in the same direction, thus forming the gap circle with different diameters.

[0050] When the gap circle diameter reaches the set diameter, the rotary motor 8 is turned off. All spokes 3 extend to the same length. The arc-shaped wheel 2 forms a circular outer arc surface that rolls on the ground. The outer arc surface is provided with resistance teeth 201, which ensures gripping force and friction during the movement.

[0051] Example 3

[0052] The diameter of the clearance circle formed by the outer contour of the arc-shaped wheel body is adjusted to either the maximum or minimum limit diameter, which is determined by the size of the arc-shaped guide hole 501 starting on the large gear. When the positioning guide post 6 slides to the maximum diameter of the arc-shaped guide hole, the clearance circle diameter reaches the maximum limit diameter. When the positioning guide post 6 slides to the minimum diameter of the arc-shaped guide hole, the clearance circle diameter reaches the minimum limit diameter.

[0053] In the description of this specification, the terms "connection," "installation," "fixing," and "setting," etc., are interpreted broadly. For example, "connection" can mean a fixed connection or an indirect connection via intermediate components without affecting the relationship between components and the technical effect; it can also mean an integral connection or a partial connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model or utility model according to the specific circumstances. The above description is only a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the protection scope of this utility model.
