Description

Technical Field

[0001] This utility model relates to the field of shared bicycle technology, specifically to a foot support structure for shared bicycles. Background Technology

[0002] In the daily use of shared bicycles, the kickstand is a key component, playing a crucial role in maintaining the stability of the bicycle when parked. However, the existing kickstand structure of shared bicycles has certain safety hazards. If the rider forgets to retract the kickstand before setting off, the unretracted kickstand may accidentally touch the ground during riding. This can not only cause the rider to lose balance and the bicycle to go out of control, but may even lead to serious traffic accidents, endangering the rider's personal safety. In addition, the accidental contact of the kickstand with the ground may also damage the kickstand itself and other parts of the bicycle, increasing the maintenance costs. Therefore, developing a structure that can automatically deploy the kickstand when it is not retracted is of great significance for improving the riding safety and stability of shared bicycles, reducing accident risks and maintenance costs. Utility Model Content

Detailed Implementation

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] Reference Figures 1-4 The present invention provides the following technical solution: In this embodiment, a foot support structure for a shared bicycle includes a bicycle body 100, a rear wheel 110 connected to the bicycle body 100, a rotating shaft 200 rotatably connected to the bicycle body 100 at the rear wheel 110, a foot support body 210 connected to the rotating shaft 200, a first connecting rod 330 hinged to the axle 300 of the rear wheel 110, a mounting plate 310 slidably connected to the end of the axle 300, a second connecting rod 320 hinged to the mounting plate 310, the ends of the first connecting rod 330 and the second connecting rod 320 being hinged together. When the foot support body 210 falls and the rear wheel 110 rotates, the axle 300 applies centrifugal force to the first connecting rod 330 and the second connecting rod 320, thereby driving the foot support body 210 to lift up at the hinged ends of the first connecting rod 330 and the second connecting rod 320.

[0020] When the vehicle is in motion, if the kickstand body 210 is not raised, the centrifugal force of the wheel axle 300 will continue to act. Since the hinge ends of the first link 330 and the second link 320 are heavier than the rest of their parts, the centrifugal force causes the hinge ends of the first link 330 and the second link 320 to gradually move away from the axis of the wheel axle 300. At this time, the hinge ends of the first link 330 and the second link 320 protrude from the side wall of the wheel axle 300, applying a rotational driving force to the pivot 200, ensuring that the kickstand body 210 is raised stably, avoiding accidental ground contact during riding, and improving riding safety and stability.

[0021] A first lever plate 220 is provided on the pivot 200, and a reversing plate 240 is rotatably connected to the vehicle body 100. The bottom end of the reversing plate 240 abuts against the first lever plate 220, and the hinge ends of the first link 330 and the second link 320 abut against the top end of the first lever plate 220.

[0022] Reference Figure 2 The rear wheel 110 Figure 2 When the direction is rolled to the left, it is in the forward direction. At this time, the hinge ends of the first link 330 and the second link 320 can move the top of the reversing plate 240, so that the reversing plate 240 is in... Figure 2 When the body rotates counterclockwise, the reversing plate 240 pushes the first lever plate 220 to make the rotating shaft 200 rotate clockwise, thereby causing the foot support body 210 to be raised.

[0023] There are multiple first links 330 and multiple second links 320, and the multiple first links 330 and multiple second links 320 are arranged in a ring array on the wheel axle 300.

[0024] By setting multiple first links 330 and second links 320, the structural stability is enhanced, so that the reversing plate 240 can be subjected to continuous thrust during driving, ensuring that the foot support body 210 can be reliably lifted. The ring array design effectively disperses the centrifugal force and extends the service life of the components.

[0025] A second lever plate 230 is fixedly connected to the pivot 200. When the foot support body 210 is raised, the second lever plate 230 pushes the reversing plate 240 to swing so that the top of the reversing plate 240 does not contact the hinge end of the first link 330 and the second link 320.

[0026] To prevent the reversing plate 240 from being continuously struck by the hinge ends of the first link 330 and the second link 320 when the kickstand body 210 is raised, causing damage and abnormal noise, the second lever 230 pushes the bottom end of the reversing plate 240 when the pivot 200 rotates and the kickstand body 210 is raised. This keeps the reversing plate 240 in an inclined state, and the top end of the reversing plate 240 no longer contacts the hinge ends of the first link 330 and the second link 320. This effectively avoids wear and noise caused by frequent impacts and improves the reliability and service life of the overall mechanical structure.

[0027] A first magnet 251 and a second magnet 252 are fixedly connected to the vehicle body 100. A magnetic rod 250 is fixedly connected to the top of the reversing plate 240. When the foot support body 210 falls, the magnetic rod 250 and the first magnet 251 are magnetically attracted to each other. When the foot support body 210 is raised, the magnetic rod 250 and the second magnet 252 are magnetically attracted to each other.

[0028] To further improve the positional stability of the commutator plate 240, when the foot support body 210 is raised and lowered, the magnetic rod 250 at the top of the commutator plate 240 can be magnetically attracted to the first magnet 251 or the second magnet 252, thus ensuring the positional stability of the commutator plate 240.

[0029] A slide rod 340 is fixedly connected to the middle of the mounting plate 310. The slide rod 340 is coaxially inserted into the wheel axle 300, and a spring 341 is connected between the slide rod 340 and the wheel axle 300.

[0030] The sliding rod 340 and spring 341 enable the mounting plate 310 to be installed. When the wheel axle 300 accelerates its rotation, the hinge ends of the first link 330 and the second link 320 move away from the wheel axle 300. At this time, multiple second links 320 apply a pulling force to the mounting plate 310, causing the mounting plate 310 to overcome the elastic force of the spring 341 and move closer to the wheel axle 300. When the rear wheel 110 is stationary or at a low speed, the spring 341 drives the mounting plate 310 to return to its original position. At this time, the hinge ends of the first link 330 and the second link 320 move closer to the wheel axle 300 to ensure the stability of the structure.

[0031] Multiple striking plates 311 are fixedly connected to the side wall of the mounting plate 310, and a hollow cylinder 312 is fixedly connected to the end of the magnetic rod 250. When the foot support body 210 falls, the reversing plate 240 is in a vertical state, so that the rotation of the mounting plate 310 can cause the multiple striking plates 311 to alternately strike the hollow cylinder 312 to produce sound.

[0032] If the hinge ends of the first link 330 and the second link 320 are far away from the wheel axle 300 and the kickstand body 210 is still not raised, the mounting plate 310 is in a position close to the wheel axle 300. As a result, the multiple striking plates 311 on the side wall of the mounting plate 310 can continuously strike the hollow cylinder 312, producing a sound to remind the user to raise the kickstand body 210 in time. If the kickstand body 210 has been raised, the magnetic rod 250 on the reversing plate 240 is attracted to the second magnet 252. At this time, the striking plates 311 separate from the hollow cylinder 312, the sound stops, and the riding is not disturbed.

[0033] This utility model provides a foot support structure for shared bicycles, and its specific working principle is as follows:

[0034] When the vehicle is in motion, if the vehicle starts to move and the rear wheel 110 rotates while the foot support body 210 is in a lowered state, the hinge ends of the first link 330 and the second link 320 are connected to the wheel axle 300. When the rear wheel 110 rotates, the centrifugal force generated by the wheel axle 300 will act on the first link 330 and the second link 320, causing the hinge ends of the two to tend to move outward. This tendency to move will be converted into a rotational driving force on the rotating shaft 200, thereby driving the foot support body 210 to gradually lift up.

[0035] During the lifting process of the foot support body 210, the interaction between the first lever plate 220 and the reversing plate 240 plays a key role in reversing direction. As the foot support body 210 is lifted, the first lever plate 220 is pushed by the hinge end of the first link 330 and the second link 320, and then transmitted through the reversing plate 240 to ensure that the rotating shaft 200 can rotate in the predetermined direction. This design not only enhances the stability of the structure, but also ensures that the foot support body 210 can be lifted smoothly and stably.

[0036] When the foot support body 210 is fully raised, the second lever 230 will take effect and push the reversing plate 240 to swing, so that the top of the reversing plate 240 no longer contacts the hinge end of the first link 330 and the second link 320. This design avoids noise and wear caused by continuous impact when the foot support body 210 is raised, and improves the reliability and service life of the overall structure.

[0037] Furthermore, this invention further enhances the positional stability of the reversing plate 240 through the magnetic attraction between the magnetic rod 250 and the first magnet 251 and the second magnet 252. During the lifting and lowering of the foot support body 210, the magnetic rod 250 can attract the first magnet 251 and the second magnet 252 respectively, ensuring that the reversing plate 240 can always remain in the predetermined position, thereby enhancing the stability and reliability of the entire structure.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
