Description

Technical Field

[0001] The present invention relates to the technical field of electric scooters, and in particular to an electric scooter capable of automatic induction braking. Background Art

[0002] As a means of transportation and fitness, electric scooters are gaining popularity and acceptance, boasting a broad market outlook. Riding a scooter requires a high level of savvy and courage, a skill perfectly suited to the imagination and adventurous nature of young people. Scooters have become a trendy sport for a new generation of young people, demonstrating their appeal comparable to skateboarding.

[0003] Currently, existing electric scooters are generally L-shaped and lightweight. When a child stands on an electric scooter and operates it independently, the scooter's center of gravity is positioned forward and upward. If an obstacle or pedestrian appears in the scooter's path, the child, due to nervousness or poor judgment, may fail to use the scooter's built-in braking system to slow down the scooter. This can easily cause the scooter to tilt or flip forward, injuring the child and pedestrians ahead. Furthermore, most existing electric scooters only have disc brakes installed on the rear wheel. If the disc brake is damaged and cannot be used, the scooter loses its braking function, posing a significant safety hazard. Summary of the Invention

[0013] Preferably, anti-slip sleeves are sleeved on both the left and right ends of the steering pipe; an anti-slip pad is pasted on the top surface of the vehicle bottom cover.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] 1. Easy to use and operate as usual: the user holds the anti-slip cover on the steering tube with both hands, stands on the anti-slip pad on the bottom cover with both feet, and lightly steps the heel of one foot on the two foot pedals, and then slowly turns the paddle on the speed regulator to drive the electric scooter to move through the motor.

[0016] 2. When the user observes with the naked eye that there is an obstacle in the moving path of the electric scooter, the user first reduces or removes the force applied to the paddle on the speed regulator, and then changes the foot that is lightly stepping on the foot pedal to stepping heavily on the two foot pedals, thereby pushing the contact column and the guide column to move backward, and the clamping bar 1 and the two clamping bars 2 move backward following the guide column. When the inner wall of the clamping bar 1 gradually approaches and contacts the front side of the rear-mounted shaft, the inner walls of the two clamping bars 2 gradually approach and contact the rear side of the rear-mounted shaft, and then gradually clamp the rear-mounted shaft and restrict the rotation of the rear-mounted shaft and the rear-mounted wheel, thereby limiting the moving speed of the electric scooter.

[0017] 3. When the photoelectric sensor detects that there is an obstacle in the moving path of the electric scooter and the user does not take the above-mentioned braking measures manually, the two motors 2 drive the corresponding push plates to move backward, thereby pushing the contact column and the guide column to move backward, and the clamping bar 1 and the two clamping bars 2 move backward following the guide column. When the inner wall of the clamping bar 1 gradually approaches and contacts the front side of the rear-mounted shaft, the inner walls of the two clamping bars 2 gradually approach and contact the rear side of the rear-mounted shaft, and then gradually clamp the rear-mounted shaft and limit the rotation of the rear-mounted shaft and the rear-mounted wheel, thereby limiting the moving speed of the electric scooter.

[0018] 4. In the above description, when the contact post moves rearward, it pushes the contact block it contacts outward, thereby disengaging the corresponding side-mounted strip from the side of the chassis. This simultaneously drives the corresponding front-mounted axle 2 and front-mounted wheel outward, disengaging the meshing wheel 2 on the front-mounted axle 2 from the meshing wheel 1 on the front-mounted axle 1. This prevents the motor 1 from further driving the front-mounted axle 2 and the front-mounted wheel, thereby limiting the speed of the electric scooter. Furthermore, the outward-moving front and rear wheels provide a larger support surface for the electric scooter, thereby reducing the possibility of the electric scooter tipping or overturning during emergency braking.

[0036] In this embodiment, the induction module 51 includes a mounting cover 501, a mounting plate 502 and a photoelectric sensor 504. The mounting cover 501 is coaxially sleeved on the lower part of the steering shaft 103.

[0037] In this embodiment, the automatic control module 52 is provided with a pair and is symmetrically distributed on the left and right. The automatic control module 52 includes a second motor 505 and a push plate 507. The second motor 505 is horizontally installed in the middle and rear part of the vehicle bottom box 101 through the second L-shaped fixing plate 506.

[0038] In this embodiment, the left and right ends of the steering tube 105 are each fitted with anti-slip sleeves 106, and the top surface of the underbody cover 119 is affixed with an anti-slip pad 120. The anti-slip sleeves 106 increase the friction and comfort of the user gripping the steering tube 105, while the anti-slip pads 120 increase the friction and comfort of the user standing on the underbody cover 119.

[0039] The actual application of this electric scooter with automatic braking includes the following usage process:

[0040] Step 1: The user holds the anti-slip cover 106 on the steering tube 105 with both hands, stands on the anti-slip pad 120 on the bottom cover 119 with both feet, and lightly steps the heel of one foot on the two footrests 310. Then, the user slowly turns the paddle on the speed regulator 127 to drive the electric scooter to move via the motor 1 121.

[0041] Step 2: When the user visually observes an obstacle in the moving path of the electric scooter, the user first reduces or removes the force applied to the paddle on the speed regulator 127, and then changes the foot that was lightly stepping on the foot pedal 310 to stepping heavily on both foot pedals 310, thereby pushing the contact column 307 and the guide column 301 to move backward. The clamping bar 1 303 and the two clamping bars 2 304 then move backward following the guide column 301. When the inner wall of the clamping bar 1 303 gradually approaches and contacts the front side of the rear shaft 117, the inner walls of the two clamping bars 2 303 gradually approach and contact the rear side of the rear shaft 117, thereby gradually clamping the rear shaft 117 and restricting the rotation of the rear shaft 117 and the rear wheel 118, thereby limiting the moving speed of the electric scooter.

[0042] Step 3: When the photoelectric sensor 504 detects an obstacle in the moving path of the electric scooter and the user does not manually take the above-mentioned braking measures, the two second motors 505 drive the corresponding push plates 507 to move backward, thereby pushing the contact column 307 and the guide column 301 to move backward. The clamping bar 1 303 and the two clamping bars 2 304 move backward following the guide column 301. When the inner wall of the clamping bar 1 303 gradually approaches and contacts the front side of the rear shaft 117, the inner walls of the two clamping bars 2 303 gradually approach and contact the rear side of the rear shaft 117, thereby gradually clamping the rear shaft 117 and restricting the rotation of the rear shaft 117 and the rear wheel 118, thereby limiting the moving speed of the electric scooter.

[0043] Step 4: In step 3 or 4, when the contact post 307 moves backward, it pushes the contact block 309 in contact with it to move outward, thereby pushing the corresponding side-mounted strip 110 out of contact with the side of the vehicle bottom box 101. At the same time, it drives the corresponding front-mounted axle 2 113 and front-mounted wheel 115 outward, thereby disengaging the meshing wheel 2 114 on the front-mounted axle 2 113 from the meshing wheel 1 109 on the front-mounted axle 1 107. This prevents the motor 121 from further driving the front-mounted axle 2 113 and the front-mounted wheel 115 to rotate, thereby limiting the speed of the electric scooter. In addition, the outward-moving two front-mounted wheels 115 and rear-mounted wheels 118 provide a larger support surface for the electric scooter, thereby reducing the possibility of the electric scooter tipping or overturning during emergency braking.

[0044] Therefore, the embodiments disclosed above are only illustrative in all aspects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are encompassed by the present invention.
