Description

Technical Field

[0001] The present invention relates to the technical field of sports equipment, and particularly to an extreme scooter. Background Art

[0002] An extreme scooter is a kind of sports equipment for extreme sports and is a new product form of skateboarding after traditional skateboards. An extreme scooter usually consists of a handlebar, a bottom plate, a front fork, a front wheel, a rear wheel, etc. Some extreme scooters also add a braking system like bicycles.

[0003] As a new form of extreme sports, in addition to being used as a means of transportation, the more common use of an extreme scooter is to perform various stunts. The more complex structure of an extreme scooter than a traditional skateboard also enables the extreme scooter to perform more complex stunt actions through combinations such as turning and lifting the handlebar, jumping and flipping the whole body.

[0004] Among various stunt actions of an extreme scooter, the rotation of the handlebar driving the front wheel as a basic action can be combined with other actions to form various stunt actions. For example, the high-level move Bar twist: when the extreme scooter passes over a high place such as a step or is in the air through the cooperation of hands and feet, rotate the handlebar and the front wheel one circle and then land.

[0005] The action of rotating the handlebar and the front wheel one circle when the extreme scooter is in the air is quite difficult. Whether for some beginners who are not proficient enough or for experienced users, during the process of completing the rotation of the handlebar in the air, the handlebar may not rotate in place, and the handlebar and the front wheel may not be rotated to 180° before landing. If the front wheel touches the ground in an inclined direction, it may cause the vehicle body to be unstable and fall, causing harm to the user. Therefore, there is an urgent need to propose an extreme scooter to assist in completing the action of rotating the handlebar in the air in common stunt actions of extreme scooters and improve safety.

[0024] 1. The extreme scooter has an auxiliary system installed in the connecting frame to assist in the basic action of rotating the handlebars and front wheels during the airborne process, which constitutes many stunts of the extreme scooter. The elastic potential energy is accumulated by the power storage component installed in the connecting frame. When the handle completes the rotation and reaches a certain degree before 180°, the elastic potential energy of the handle is released through the trigger component, and the handle is twisted by elastic force to assist the handle to rotate to 180°.

[0025] 2. The extreme scooter is provided with two groups of auxiliary systems, and the two groups of auxiliary systems are rotationally symmetrical in the connecting frame. They correspond to clockwise rotation assistance and counterclockwise rotation assistance respectively. And the gear position can be adjusted through the control mechanism. By pulling out the second latch, the sleeve arranged on the outside of the handle is released, and the sleeve is pulled to slide, and then re-engaged in another second slot to complete the gear adjustment between clockwise assisted rotation, non-assisted rotation and counterclockwise assisted rotation. And during the installation process, by adjusting the initial position of the guide block in the trigger assembly in the spiral track, the stroke of the trigger assisted rotation condition can be adjusted to meet the different assistance needs of the rider.

[0026] 3. The extreme scooter is very convenient to use and operate automatically. When adjusting the gear, you only need to pull out the second latch and then buckle it again. The triggering of the auxiliary rotation is also automatic. When resetting, you only need to turn the handle normally. For example, when the second latch is buckled in the clockwise rotation auxiliary gear, the trigger component triggers the auxiliary clockwise rotation to °, and then rotates the handle counterclockwise to complete the power storage component to store power again, so as to complete the next auxiliary rotation.

Detailed implementation manners

[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0039] Embodiment 1

[0040] Flipping the handlebar 150 and the front wheel 130 180° during the vacancy process is one of the basic actions of many stunts that constitute the extreme scooter. This action is relatively difficult. If the handlebar 150 is not flipped into place during the vacancy process, the front wheel 130 will fall to the ground at an inclined angle, which will cause the body of the scooter to be unstable and fall over, posing a threat to the safety of the user. Therefore, in order to solve the above problems, an extreme scooter is proposed;

[0041] See also Figures 1 - 10 , comprising a base plate 100, a connecting frame 110 and a rear wheel 140 are arranged on the base plate 100, a front fork 120 is rotatably arranged on the connecting frame 110, a handle 150 is arranged on the front fork 120, and a front wheel 130 is arranged on the handle 150;

[0042] The connecting frame 110 is provided with an auxiliary system 200, the auxiliary system 200 includes a power storage assembly 210, the power storage assembly 210 includes a fixed cylinder 211 provided on the connecting frame 110, a rotating cylinder 212 is rotatably provided on the fixed cylinder 211, a rotating groove 213 is provided on the fixed cylinder 211, a rotating ring 214 is rotatably provided in the rotating groove 213, a torsion spring 215 is provided on the rotating ring 214, and the torsion spring 215 is connected to the inner wall of the rotating groove 213;

[0043] The rotating ring 214 is connected to the rotating cylinder 212, and the rotating cylinder 212 is connected to the handle 150. The torsion spring 215 accumulates elastic potential energy and releases it to assist the handle 150 in rotating.

[0044] The auxiliary system 200 further includes a connecting assembly 220 and a transmission assembly 230. The rotating ring 214 is connected to the rotating cylinder 212 through the transmission assembly 230 so that the rotating ring 214 drives the rotating cylinder 212 to rotate when the torsion spring 215 releases elastic potential energy. The rotating cylinder 212 is connected to the handle 150 through the connecting assembly 220 so that the rotating cylinder 212 drives the handle 150 to rotate.

[0045] The auxiliary system 200 also includes a fixing component 240 and a trigger component 250. The fixing component 240 is used to fix the torsion spring 215 in a twisted state to accumulate elastic potential energy. The trigger component 250 is connected to both the handle 150 and the fixing component 240 to enable the handle 150 to release the elastic potential energy by releasing the fixing component 240 from the torsion spring 215 through the trigger component 250 during the rotation process.

[0046] In this embodiment, the base plate 100, the connecting frame 110, the front fork 120, the front wheel 130, the rear wheel 140 and the handle 150 are the main structures of the extreme scooter, wherein the front fork 120 is rotatably mounted on the connecting frame 110, and the handle 150 is fixed to the front fork 120 and the front wheel 130.

[0047] Inside the cylindrical cavity of the connecting frame 110, a fixed cylinder 211 with an upward opening is fixed. Inside the upper cavity of the fixed cylinder 211, a rotating cylinder 212 is rotatably installed. The rotating cylinder 212 also has an upward opening, and the rotating cylinder 212 is connected to the handle 150 through a connecting component 220. When the handle 150 rotates, it drives the rotating cylinder 212 to rotate.

[0048] An annular rotating groove 213 is formed in the lower inner wall of the fixed cylinder 211. A rotating ring 214 is rotatably installed in the rotating groove 213. The two ends of a torsion spring 215 are respectively fixed to the bottom end of the rotating ring 214 and the bottom wall of the rotating groove 213.

[0049] When the torsion spring 215 is in a twisted state and accumulates elastic potential energy, the torsion spring 215 is fixed by a fixing component 240. During the process of rotating the handlebar, the handle 150 drives the rotating cylinder 212 to rotate. When it reaches a certain degree, through a triggering component 250, the fixing of the torsion spring 215 by the fixing component 240 is released, and its elastic potential energy is released.

[0050] The transmission component 230 is connected to both the rotating cylinder 212 and the rotating ring 214. Its function is that when the rotating cylinder 212 rotates, it will not drive the rotating ring 214 to rotate, so as not to affect the fixed torsion spring 215 at this time. When the torsion spring 215 drives the rotating ring 214 to rotate, the transmission component 230 will in turn drive the rotating cylinder 212 to rotate, driving the handle 150 to rotate, and the rotation direction is the same as the rotation direction of the handle 150. Thus, it assists the handle 150 to complete the rotation action and improves safety.

[0051] It should be supplemented and explained that damping devices and other components for absorbing and buffering vibrations can be installed in the rotating groove 213 and connected to the torsion spring 215 to avoid the large turning force on the handle 150 caused by the elastic force of the torsion spring 215 during the rotation assistance.

[0052] Embodiment 2

[0053] To achieve the transmission between the handle 150 and the rotating cylinder 212, and the one-way transmission between the rotating ring 214 and the rotating cylinder 212, Embodiment 2 is proposed;

[0054] This embodiment is an improved description based on Embodiment 1. Specifically, please refer to Figures 2 - 10 , a sleeve 160 is slidably arranged on the handle 150. The connecting component 220 includes a connecting groove 221 formed on the rotating cylinder 212, and a connecting block 222 matching the connecting groove 221 is arranged on the sleeve 160;

[0055] The transmission assembly 230 includes a turntable 231 disposed on the swivel ring 214. A ratchet wheel 232 is provided on the rotating cylinder 212. Two ratchet pawls 233 are rotatably disposed on the turntable 231, and both of the two ratchet pawls 233 are engaged with the ratchet wheel 232. Two first spring pieces 234 are provided on the turntable 231.

[0056] In this embodiment: A cross-shaped connection groove 221 is formed in the circumferential inner wall of the rotating cylinder 212. A sleeve 160 is slidably mounted on the handle 150. A part of the surface of the handle 150 is polygonal, and a part of the inner wall of the sleeve 160 is a fitting polygon, so that when the sleeve 160 slides up and down along the surface of the handle 150, the handle 150 can also be driven to rotate.

[0057] A cross-shaped connection block 222 is fixed on the sleeve 160. When the connection block 222 extends into the connection groove 221, the rotation of the handle 150 drives the sleeve 160 and the connection block 222 to rotate, and then drives the rotating cylinder 212 to rotate.

[0058] The turntable 231 is fixed to the upper end of the swivel ring 214. The ratchet wheel 232 is fixed to the lower end of the rotating cylinder 212. Two ratchet pawls 233 are symmetrically and rotatably mounted on the upper end of the turntable 231. Two first spring pieces 234 are fixed to the inner wall of the turntable 231. The elastic forces of the two first spring pieces 234 press the two ratchet pawls 233 against the ratchet wheel 232.

[0059] The tooth direction of the ratchet wheel 232 is counterclockwise. When the handle 150 rotates counterclockwise, it drives the ratchet wheel 232 to rotate counterclockwise. At this time, the rotation direction of the ratchet wheel 232 is the same as the tooth direction of the two ratchet pawls 233. The ratchet wheel 232 only drives the two ratchet pawls 233 to vibrate repeatedly under the elastic force of the two first spring pieces 234, and does not drive the turntable 231 to rotate, which will not affect the swivel ring 214 fixed by the fixing assembly 240 at this time.

[0060] When the elastic potential energy of the torsion spring 215 is released, causing the swivel ring 214 and the turntable 231 to rotate counterclockwise, the rotation direction of the two ratchet pawls 233 is opposite to the tooth direction of the ratchet wheel 232. At this time, the two ratchet pawls 233 will catch the ratchet wheel 232 and drive the ratchet wheel 232 to rotate counterclockwise, thereby driving the handle 150 to rotate counterclockwise.

[0061] The handle 150 and the sleeve 160 pass through the rotating cylinder 212, the ratchet wheel 232, the turntable 231, the swivel ring 214, the torsion spring 215 and the fixed cylinder 211, etc. and do not contact them.

[0062] Embodiment 3

[0063] In order to trigger the handle 150 to release the elastic potential energy to assist rotation when the handle 150 rotates to a certain extent, Embodiment 3 is proposed;

[0064] This embodiment is an improved description based on Embodiment 2. Specifically, please refer to Figures 2 - 9 , the fixing component 240 includes a first sliding groove 241 formed in the fixing cylinder 211. A first bolt 242 is slidably arranged in the first sliding groove 241. A first slot 243 is formed in the turntable 231, and the first bolt 242 is movably inserted into the first slot 243. A first spring 244 is arranged on the first bolt 242, and the first spring 244 is connected to the inner wall of the first sliding groove 241;

[0065] The triggering component 250 includes a spiral groove 251 formed in the fixing cylinder 211, and the spiral groove 251 communicates with the first sliding groove 241;

[0066] A spiral track 252 is arranged in the spiral groove 251. A second sliding groove 253 is formed in the rotating cylinder 212. A guiding block 254 is slidably arranged in the second sliding groove 253, and the guiding block 254 is slidably arranged on the spiral track 252. A second spring piece 255 is arranged on the first bolt 242, and the second spring piece 255 is slidably arranged on the spiral track 252, and the second spring piece 255 matches the guiding block 254.

[0067] In this embodiment: a spiral groove 251 is formed in the inner wall of the fixing cylinder 211, and the spiral track 252 is fixed in the spiral groove 251. A linear second sliding groove 253 is formed in the inner wall of the rotating cylinder 212. The guiding block 254 slides up and down along the second sliding groove 253. When the handle 150 rotates to drive the rotating cylinder 212 to rotate, the part of the guiding block 254 extending out of the rotating cylinder 212 will move downward in a spiral along the spiral track 252.

[0068] A first sliding groove 241 is formed in the inner wall of the fixing cylinder 211. A first bolt 242 is slidably installed in the first sliding groove 241. A first slot 243 is formed in the side end of the turntable 231. Two ends of the first spring 244 are respectively fixed on the first bolt 242 and the inner wall of the first sliding groove 241. The first bolt 242 is fixed in the first slot 243 by the elastic force of the first spring 244 to fix the turntable 231.

[0069] A second spring piece 255 is further fixed on the upper end of the first bolt 242, and the second spring piece 255 extends into the spiral track 252. When the guiding block 254 moves downward in a spiral along the spiral track 252 and touches the second spring piece 255, it will push the second spring piece 255 towards the outside of the fixing cylinder 211, driving the first bolt 242 to be pulled out of the first slot 243, thereby releasing the fixation of the turntable 231, the rotating ring 214 and the torsion spring 215.

[0070] After assisting in the counterclockwise rotation of the handle 150, during the restoration process of the fixing component 240, the triggering component 250, etc., the handle 150 rotates clockwise. At this time, the handle 150 drives the ratchet wheel 232 to rotate clockwise, driving the turntable 231 and the rotating ring 214 to rotate clockwise until they are clamped and fixed again when the first slot 243 and the first pin 242 are rematched, and elastic potential energy is stored for the torsion spring 215 again. At the same time, the guiding block 254 also moves spirally upward along the spiral track 252 and returns to the initial position.

[0071] It should be supplemented and explained that during the assembly process, the initial position of the guiding block 254 in the spiral track 252 can be adjusted, so as to adjust the stroke of the process of triggering the auxiliary rotation.

[0072] Embodiment 4

[0073] The above solution only shows the auxiliary rotation of the handle 150 during counterclockwise rotation, and the special action does not limit the direction. The handle 150 also needs to rotate clockwise. In order to assist the clockwise rotation of the handle 150 as well, Embodiment 4 is proposed;

[0074] This embodiment is an improved description based on Embodiment 3. Specifically, please refer to Figures 2 - 8 , two auxiliary systems 200 are provided, and the two auxiliary systems 200 are symmetrically arranged on the connecting frame 110, and the two connecting blocks 222 in the two auxiliary systems 200 are connected.

[0075] In this embodiment: Another set of auxiliary systems 200 is symmetrically installed and rotated inside the connecting frame 110. In the other set of auxiliary systems 200, the opening of the fixed cylinder 211 faces downward, the tooth direction of the ratchet wheel 232 is clockwise, and the direction of the spiral track 252 is also opposite.

[0076] And the contact surfaces of the two connecting blocks 222 are connected. When the sleeve 160 slides upward so that the upper connecting block 222 is connected to the upper connecting groove 221, the lower connecting block 222 is not connected to the lower connecting groove 221. At this time, the handle 150 can complete the auxiliary rotation during clockwise rotation through the upper auxiliary system 200.

[0077] Embodiment 5

[0078] In order to control the connection between the handle 150 and the two auxiliary systems 200 and switch between auxiliary clockwise rotation, auxiliary counterclockwise rotation, and no auxiliary rotation, Embodiment 5 is proposed;

[0079] This embodiment is an improved description based on Embodiment 4. Specifically, please refer to Figures 1 - 7The front fork 120 is provided with a control mechanism 300 for controlling the connection between the handlebar 150 and the two auxiliary systems 200. The control mechanism 300 includes a connection seat 310 slidably provided on the front fork 120, and the sleeve 160 is rotatably provided on the connection seat 310;

[0080] A second latch 320 is slidably disposed on the connecting seat 310 , a plurality of second slots 330 are opened on the front fork 120 , and the second latch 320 matches the plurality of second slots 330 , a second spring 340 is disposed on the second latch 320 , and the second spring 340 is connected to the connecting seat 310 .

[0081] In this embodiment, a connecting seat 310 is slidably mounted on the front fork 120, the sleeve 160 is rotatably mounted in the connecting seat 310, a second latch 320 is slidably mounted on the portion of the connecting seat 310 extending out of the front fork 120, and three second slots 330 are provided in a straight line direction on the front fork 120. The second latch 320 is elastically connected to the connecting seat 310 via a second spring 340.

[0082] After the connection base 310 is released by pulling out the second pin 320, the sliding connection base 310 drives the sleeve 160 to slide up and down, and is adjusted to the clockwise auxiliary rotation position, the non-auxiliary position and the counterclockwise auxiliary rotation position, and then the second pin 320 is re-locked in the corresponding second slot 330 to complete the adjustment.

[0083] Example 6

[0084] In order to prevent the auxiliary system 200 that is not connected to the handle 150 from rotating unsteadily during the rotation of the handle 150 and the movement of the vehicle body, embodiment 6 is proposed;

[0085] This embodiment is an improvement made on the basis of embodiment 5. For details, please refer to Figures 2 - 9 A limiting mechanism 400 is disposed on the connecting frame 110. The limiting mechanism 400 includes two limiting components 410 and a resisting block 420.
