Description

Technical Field

[0001] This invention belongs to the field of transportation vehicles, and specifically relates to a scooter. Background Technology

[0002] A scooter is a mode of transportation made of wood, metal, or other materials. It typically consists of two or three wheels and a handlebar. People stand on the board and push off with their feet to propel it forward. It can be used for daily commuting, as well as leisure and sports. Scooters help people quickly navigate urban areas, reducing traffic congestion and contributing to environmental protection. While scooters are a convenient mode of transportation, they also have some drawbacks, especially three-wheeled scooters. These consist of two front wheels and a rear wheel, with the two front wheels connected on the same axle. This poses a safety hazard when turning. Existing three-wheeled scooters, because the two front wheels turn with the same radius, have limited deflection angles when turning at high speeds or with sharp turns. This can cause the front wheels to skid and bounce violently, resulting in a loss of traction. Furthermore, existing scooters cannot be folded, leading to poor portability. They cannot be carried to public transportation or other public places, require large storage spaces, and are inconvenient for travel. The non-foldable nature of scooters affects both carrying and storage. Summary of the Invention

[0003] To address the problems existing in the prior art, this invention provides a foldable scooter that supports Ackerman steering, improving passenger comfort. The foldable structure and simple operation make it easy to use.

[0004] According to one embodiment of the present invention, a scooter is provided, comprising a body body, a footboard, a folding control bar, a handlebar, a front wheel, a rear wheel, a shock-absorbing chassis, a frame, and side shock absorbers. The folding control bar is disposed at the front end of the footboard, the front wheel is connected to both ends of the shock-absorbing chassis, and the rear wheel is disposed at the rear end of the footboard. The folding control bar includes an upper bar and a lower bar, with a folding structure between the upper bar and the lower bar. The upper bar and the lower bar are connected via a rotating structure. The upper bar is connected to the handlebar, and the lower bar is connected to the shock-absorbing chassis. Both ends of the frame are connected to the lower bar and the footboard, respectively. Both ends of the side shock absorbers are connected to the shock-absorbing chassis and the lower bar, respectively.

[0005] Furthermore, the folding structure includes an upper convex plate, a lower convex plate, a pin, a pull ring, a spring, and an anti-detachment plate. The upper convex plate is located at the top of the lower rod, and the lower convex plate is located at the bottom of the upper rod. Both the upper and lower rods are tubular. The folding structure is accommodated within the cavity of the upper rod. Part of the upper convex plate and part of the lower convex plate overlap in a staggered manner. The overlapping part has a first through hole corresponding to the position. The pin includes a rod and an enlarged part. The enlarged part is connected to one end of the rod and is located outside the upper rod. The pull ring is connected to the enlarged part. The rod is inserted into the first through hole. The spring is sleeved on the rod between the lower convex plate and the tube wall of the upper rod. A second through hole is formed on the tube wall of the upper rod for the rod to pass through. The anti-detachment plate is fixed on the rod between the spring and the lower convex plate.

[0006] Furthermore, the rotating structure includes a first bearing, a second bearing, and a pivot. The first bearing is located at the bottom end of the upper rod, and the second bearing is located at the top end of the lower rod. The first bearing includes two first protrusions, each with a third through hole. The second bearing includes a second protrusion, each with a fourth through hole. The second protrusion is located between the first protrusions, and the pivot passes through the first and second protrusions.

[0007] Furthermore, the side shock absorber includes a sleeve, a telescopic rod, and a first telescopic spring. There are two side shock absorbers, distributed on the left and right sides of the folding control rod. The sleeve is hinged to the lower rod. The telescopic rod slides and extends along the inner wall of the sleeve. The first telescopic spring is located inside the sleeve above the telescopic rod. A fifth through hole is opened at the end of the telescopic rod away from the sleeve.

[0008] Furthermore, the shock-absorbing chassis includes an outer frame, a left support frame, a right support frame, lugs, and a central axle. The left and right support frames are located within the outer frame on both sides of the central axle. The left and right support frames each include a front trapezoidal frame and a rear trapezoidal frame, respectively. A crossbar connects the front and rear trapezoidal frames, and the crossbar passes through a fifth through hole. The side shock absorber rotates around the crossbar as an axis. There are two lugs, which are connected to the left and right ends of the outer frame. A sixth through hole is formed on the lug, and the sixth through hole is connected to the front wheel axle.

[0009] Furthermore, a telescopic upright is provided inside the lower rod's cylindrical cavity, and a second telescopic spring is provided in the cylindrical cavity above the telescopic upright. The end of the telescopic upright away from the second telescopic spring is inserted into the short tube. The short tube and the telescopic upright have corresponding seventh through holes. The central axis passes through the seventh through hole, allowing the folding control rod to rotate around the central axis.

[0010] Furthermore, the grip surface is provided with anti-slip protrusions.

[0011] Furthermore, the scooter body also includes a rear fork, a rear mudguard, and a front mudguard. The rear fork connects the rear wheel to the footboard, the rear mudguard covers the rear wheel, and the front mudguard covers the front wheel.

[0012] The beneficial effects of this invention are:

[0013] By incorporating side shock absorbers, a first telescopic spring, a second telescopic spring, and a shock-absorbing chassis, the two side shock absorbers have different lengths when the scooter turns. Simultaneously, the folding steering lever rotates inward around the central axis, compressing the second telescopic spring. This causes the two front wheels to point to different centers, achieving Ackerman steering and making the scooter more stable during turns, reducing sideslip. The rotating structure enables a rotatable connection between the upper and lower bars, ensuring a stable and smooth connection and preventing loosening. During operation, the upper bar rotates downward around the pivot axis to fold the steering lever, and rotates upward around the pivot axis to unfold it. The folding structure allows the scooter to fold, reducing the height of the folding steering lever for easier storage and carrying. The handlebars help users control direction and balance, while the shock-absorbing chassis and side shock absorbers reduce the feeling of bumps on rough roads. Attached Figure Description

[0025] As shown in the figure, the present invention provides a scooter, which includes a body body 1, a footboard 2, a folding control bar 3, a handlebar 4, a front wheel 5, a rear wheel 6, a shock-absorbing chassis 7, a frame 8, and side shock-absorbing bars 9. The folding control bar 3 is located at the front end of the footboard 2. The front wheel 5 is connected to both ends of the shock-absorbing chassis 7, and the rear wheel 6 is located at the rear end of the footboard 2. The folding control bar 3 includes an upper bar 301 and a lower bar 302. A folding structure 303 is provided between the upper bar 301 and the lower bar 302. The upper bar 301 and the lower bar 302 are connected by a rotating structure 10. The upper bar 301 is connected to the handlebar 4, and the lower bar 302 is connected to the shock-absorbing chassis 7. Both ends of the frame 8 are connected to the lower bar 302 and the footboard 2, respectively. Both ends of the side shock-absorbing bars 9 are connected to the shock-absorbing chassis 7 and the lower bar 302, respectively. In practical applications, the folding steering lever 3 is located at the front end of the footrest 2, the front wheel 5 is connected to both ends of the shock-absorbing chassis 7, and the rear wheel 6 is located at the rear end of the footrest 2. The folding steering lever 3 includes an upper lever 301 and a lower lever 302, with a folding structure 303 between the upper lever 301 and the lower lever 302. The upper lever 301 is connected to the handlebar 4, and the lower lever 302 is connected to the shock-absorbing chassis 7. Both ends of the vehicle beam 8 are connected to the lower lever 302 and the footrest 2, respectively, and both ends of the side shock absorber 9 are connected to the shock-absorbing chassis 7 and the lower lever 302, respectively. In this way, the height of the folding steering lever 3 is reduced by the folding structure 303, making it convenient for storage and carrying. The handlebar 4 helps the user control the direction and balance, and the shock-absorbing chassis 7 and the side shock absorber 9 reduce the feeling of bumps on bumpy roads.

[0026] The folding structure 303 includes an upper convex plate 3031, a lower convex plate 3032, a pin 3033, a pull ring 3034, a spring 3035, and an anti-detachment plate 3036. The upper convex plate 3031 is located at the top of the lower rod 302, and the lower convex plate 3032 is located at the bottom of the upper rod 301. Both the upper rod 301 and the lower rod 302 are tubular. The folding structure 303 is housed within the cavity of the upper rod 301. Part of the upper convex plate 3031 and part of the lower convex plate 3032 overlap in a staggered manner, and the overlapping part has a first through hole corresponding to the position. The pin 3033 includes a insertion rod 3033. 1 and the enlarged part 30332, the enlarged part 30332 is connected to one end of the insertion rod 30331, the enlarged part 30332 is located outside the upper rod 301, the pull ring 3034 is connected to the enlarged part 30332, the insertion rod 30331 is inserted into the first through hole, the spring 3035 is sleeved on the insertion rod 30331 between the lower convex plate 3032 and the tube wall of the upper rod 301, a second through hole is formed on the tube wall of the upper rod 301 for the insertion rod 30331 to pass through, and the anti-detachment plate 3036 is fixed on the insertion rod 30331 between the spring 3035 and the lower convex plate 3032. In specific applications, the folding structure 303 includes an upper convex plate 3031, a lower convex plate 3032, a pin 3033, a pull ring 3034, a spring 3035, and an anti-detachment plate 3036. The upper convex plate 3031 is located at the top of the lower rod 302. Both the upper rod 301 and the lower rod 302 are tubular. The bottom end of the upper rod 301 is provided with a radial partition 3037. The lower convex plate 3032 is fixed on the partition 3037. The top end of the lower rod 302 is closed. The folding structure 303 is accommodated in the cavity below the partition 3037. Part of the upper convex plate 3031 and part of the lower convex plate 3032 are misaligned and overlapped. The overlapping part has corresponding openings. The first through hole, the pin 3033 includes a rod 30331 and an enlarged part 30332. The enlarged part 30332 is connected to one end of the rod 30331. The pull ring 3034 is connected to the enlarged part 30332. The enlarged part 30332 is located outside the upper rod 301. The rod 30331 is inserted into the first through hole. The spring 3035 is sleeved on the rod 30331 between the lower convex plate 3032 and the tube wall of the upper rod 301. A second through hole is formed on the tube wall of the upper rod 301 for the rod 30331 to pass through. The anti-detachment plate 3036 is fixed on the rod 30331 between the spring 3035 and the lower convex plate 3032.Thus, during the use of the scooter, when it is necessary to fold the folding control lever 3, the user holds the pull ring 3034 and pulls the insert rod 30331 outward until the insert rod 30331 can no longer be pulled out. At this time, the anti-detachment plate 3036 compresses the spring 3035, the spring 3035 is in a compressed state, and the end of the insert rod 30331 away from the expansion part 30332 comes out of the first through hole. The upper rod 301 folds downward, and the upper convex plate 3031 and the lower convex plate 3032 are in a non-overlapping state. After folding is completed, the pull ring 3034 is released. When it is necessary to unfold the folding control lever 3, the upper rod 301 is opened upward, and the insert rod 30331 is pulled outward until the upper convex plate 3031 and the lower convex plate 3032 are misaligned and overlapped. At this time, the pull ring 3034 is released, and the insert rod 30331 is inserted into the first through hole, so that the upper rod 301 and the lower rod 302 are fixed together. Since the anti-detachment plate 3036 is a ring plate, and the inner diameter of the anti-detachment plate 3036 is the same as the diameter of the insertion rod 30331, it plays the role of preventing the insertion pin 3033 from falling off.

[0027] The rotating structure 10 includes a first bearing 1001, a second bearing 1002, and a pivot 1003. The first bearing 1001 is disposed at the bottom end of the upper rod 301, and the second bearing 1002 is disposed at the top end of the lower rod 302. The first bearing 1001 includes a first protrusion with a third through hole. The second bearing 1002 includes a second protrusion with a fourth through hole. The second protrusion is disposed between the first protrusions, and the pivot 1003 passes through the first and second protrusions. In specific applications, the rotating structure 10 includes a first bearing 1001, a second bearing 1002, and a pivot 1003. The first bearing 1001 is located at the bottom of the upper rod 301, and the second bearing 1002 is located at the top of the lower rod 302. The first bearing 1001 includes two parallel first protrusions that protrude from the upper rod 301 and have a third through hole. The second bearing 1002 includes a second protrusion that has a fourth through hole and is located between the first protrusions. The third through hole and the fourth through hole are coaxial. The pivot 1003 passes through the first protrusion and the second protrusion. This achieves a rotatable connection between the upper rod 301 and the lower rod 302, ensuring the stability and smoothness of the connection and preventing the rotatable connection between the upper rod 301 and the lower rod 302 from loosening. During operation, the upper rod 301 rotates downward around the pivot 1003 to fold the folding control rod 3, and the upper rod 301 rotates upward around the pivot 1003 to unfold the folding control rod 3.

[0028] The side shock absorber 9 includes a sleeve 901, a telescopic rod 902, and a first telescopic spring. There are two side shock absorbers 9, which are distributed on the left and right sides of the folding control rod 3. The sleeve 901 is hinged to the lower rod 302. The telescopic rod 902 slides and extends along the inner wall of the sleeve 901. The first telescopic spring is set in the sleeve 901 above the telescopic rod 902. A fifth through hole is opened at the end of the telescopic rod 902 away from the sleeve 901. In practical applications, since the side shock absorber 9 includes a sleeve 901, a telescopic rod 902, and a first telescopic spring, there are two side shock absorbers 9, distributed on the left and right sides of the folding control rod. The sleeve 901 is hinged to the lower rod 302. The telescopic rod 902 extends and retracts along the sleeve 901. The first telescopic spring is set inside the sleeve 901 above the telescopic rod 902. A fifth through hole is opened at the end of the telescopic rod 902 away from the sleeve 901. In this way, the telescopic rod 902 slides along the sleeve 901, and the first telescopic spring is in a compressed or extended state. The first telescopic spring absorbs and reduces the impact and vibration of the scooter during the ride.

[0029] The shock-absorbing chassis 7 includes an outer frame 701, a left support frame 702, a right support frame 703, lugs 704, and a central shaft 705. The left support frame 702 and the right support frame 703 are located inside the outer frame 701 on both sides of the central shaft 705. The left support frame 702 and the right support frame 703 respectively include a front trapezoidal frame 706 and a rear trapezoidal frame 707. A crossbar 708 is connected between the front trapezoidal frame 706 and the rear trapezoidal frame 707. The crossbar 708 passes through a fifth through hole. The side shock-absorbing rod 9 rotates around the crossbar 708. There are two lugs 704, which are connected to the left end and the right end of the outer frame 701. A sixth through hole is formed on the lug 704, and the sixth through hole is connected to the axle of the front wheel 5. In practical applications, the shock-absorbing chassis 7 includes an outer frame 701, a left support frame 702, a right support frame 703, lugs 704, and a central shaft 705. The left support frame 702 and the right support frame 703 are located within the outer frame 701 on both sides of the central shaft 705. The left support frame 702 and the right support frame 703 respectively include a front trapezoidal frame 706 and a rear trapezoidal frame 707. A crossbar 708 connects the front trapezoidal frame 706 and the rear trapezoidal frame 707. The crossbar 708 passes through a fifth through hole, and the side shock-absorbing rod 9 rotates around the crossbar 708. The lugs 704 are two... A sixth through hole is formed on the lug 704, which is connected to the left and right ends of the outer frame 701. The sixth through hole is connected to the axle of the front wheel 5. In this way, the left support frame 702 and the right support frame 703 effectively support the weight of the vehicle and provide sufficient rigidity. The front trapezoidal frame 706 and the rear trapezoidal frame 707 provide good structural support, which helps to reduce the vibration and bumps of the scooter during driving. The connection of the crossbar 708 increases the stability of the entire shock-absorbing chassis structure. The lug 704 is connected to the axle of the front wheel 5 to transmit rotational motion force and improve steering stability.

[0030] The lower rod 302 has a telescopic upright 11 inside its cylindrical cavity. A second telescopic spring 12 is located in the cylindrical cavity above the telescopic upright 11. The end of the telescopic upright 11 away from the second telescopic spring 12 is inserted into a short tube 13. A seventh through hole is opened on both the short tube 13 and the telescopic upright 11, corresponding to each other. The central shaft 705 passes through the seventh through hole, allowing the folding control rod 3 to rotate around the central shaft 705. In practical applications, the lower rod 302 has a telescopic upright 11 that slides up and down within its cylindrical cavity. A second telescopic spring 12 is located in the cylindrical cavity above the telescopic upright 11. The end of the telescopic upright 11 away from the second telescopic spring 12 is inserted into a short tube 13. A seventh through hole is opened on both the short tube 13 and the telescopic upright 11, corresponding to each other. The central shaft 705 of the chassis passes through the seventh through hole, allowing the folding control rod 3 to rotate around the central shaft 705. In this way, when encountering uneven road surfaces, the second telescopic spring 12 acts as a shock absorber, reducing bumps and vibrations and ensuring smooth driving. Through the coordinated action of the telescopic pole 11 and the second telescopic spring 12, the suspension state of the folding control bar 3 can be effectively adjusted and controlled, so that the scooter can remain stable under different road conditions, improving the scooter's passability and handling performance.

[0031] The grip 4 has anti-slip protrusions on its surface. In practical applications, the anti-slip protrusions on the grip 4 increase the friction when the user grips the grip 4, improving the stability and safety of operation. The anti-slip protrusions effectively prevent the hand from slipping and reduce the occurrence of accidents.

[0032] The scooter frame 1 also includes a rear fork 14, a rear mudguard 15, and a front mudguard 16. The rear fork 14 is connected between the rear wheel 6 and the footrest 2. The rear mudguard 15 covers the rear wheel 6, and the front mudguard 16 covers the front wheel 5. In practical applications, since the scooter also includes a rear fork 14, a rear mudguard 15, and a front mudguard 16, with the rear fork 14 connected between the rear wheel 6 and the footrest 2, the rear mudguard 15 covering the rear wheel 6, and the front mudguard 16 covering the front wheel 5, the rear mudguard 15 and the front mudguard 16 protect the rear wheel 6 and the front wheel 5, preventing mud, water, or other debris from splashing onto the rider and maintaining cleanliness and comfort during riding.

[0033] When the scooter turns, the different road conditions encountered by the two front wheels 5 result in different heights for the two front wheels 5. The extension and contraction states of the first telescopic springs of the inner and outer shock absorbers are different, with the compression of the inner first telescopic spring being greater than that of the outer first telescopic spring. This causes the lengths of the two side shock absorbers 9 to be different, with the inner shock absorber being shorter than the outer shock absorber. At the same time, the folding control rod 3 rotates inward around the central axis 705, and the second telescopic spring 12 is compressed. This causes the two front wheels 5 to point to different centers of rotation, achieving Ackerman steering. This makes the scooter more stable when turning and reduces sideslip during turns.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the inventive concept, and these all fall within the scope of protection of the present invention.
