They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-3A high-safety intelligent mobility scooter includes a footrest 1, with wheel covers 2 at both ends of the footrest 1. Each wheel cover 2 contains a walking wheel 3. A wheel frame 4 is located between the two walking wheels 3 on the same side. A cylindrical seat 5 is fixedly connected to the upper center of each wheel frame 4. A fixing seat 6 is fixedly connected to the lower end of each wheel cover 2 opposite to the cylindrical seat 5. A circular groove 7 is provided at the upper end of each cylindrical seat 5. A buffer mechanism is provided within each circular groove 7. A fixing block 8 is provided at the upper end of each buffer mechanism. The buffer mechanism includes a fixed block 8. A first damping spring 10 and a buffer airbag 11 are located at the bottom of the circular groove 7. The first damping spring 10 is sleeved on the buffer airbag 11. The upper ends of the first damping spring 10 and the buffer airbag 11 are fixedly connected to the same movable rod 12. The lower end of the center of the fixed block 8 is fixedly connected to the upper end of the movable rod 12. Two symmetrically distributed sliders 13 are fixedly connected to the annular sidewall of the movable rod 12 near its lower end. Two symmetrically distributed sliding grooves 14 are provided on the annular inner wall of the circular groove 7. The two sliders 13 are respectively inserted into the two sliding grooves 14 and slide. The two sliding grooves 14 are in contact with each other, and their top surfaces are connected to the upper end of the cylindrical seat 5. When the intelligent mobility scooter is running with the walking wheels 3, the vehicle body is subjected to force, which, together with the fixed seat 6 and the fixed block 8, drives the movable rod 12 to compress the first damping spring 10 and the buffer airbag 11 in the circular groove 7 under the limiting action of the sliding groove 14 and the slider 13. This causes the first damping spring 10 and the buffer airbag 11 to work together with the movable rod 12 to provide damping and buffering for the vehicle body in the vertical direction under the limiting action of the sliding groove 14 and the slider 13. One end of the movable rod 12 located outside the circular groove 7 is fitted with a sleeve. A sealing ring 15 is attached, and the lower end of the sealing ring 15 is fixedly connected to the upper end of the cylindrical seat 5. The sealing ring 15 can prevent impurities from entering the circular groove 7. Roller balls 16 are embedded in the inner walls of the left and right sides of the two rectangular grooves 9. The left and right side walls of the two fixing blocks 8 are provided with strip-shaped arc-shaped slots 17. The two roller balls 16 are respectively inserted into the two strip-shaped arc-shaped slots 17 and roll and abut against each other. When the roller balls 16 move along the strip-shaped arc-shaped slots 17 on the side of the fixing block 8, they can provide a limit to the fixing block 8, so that it can move smoothly along the rectangular grooves 9.

[0022] Both fixed seats 6 have rectangular grooves 9 at their lower ends. Two fixed blocks 8 are inserted into the two rectangular grooves 9 and locked in place. The upper end of the fixed blocks 8 has a strip groove 18. A horizontal limiting rod 19 is vertically inserted through the inner walls of the front and rear sides of the strip groove 18. The front and rear ends of the horizontal limiting rod 19 are respectively horizontally inserted through the inner walls of the front and rear sides of the rectangular groove 9. The front and rear ends of the horizontal limiting rod 19 outside the rectangular groove 9 are provided with threaded protrusions 20. Nuts 21 are threaded onto the two threaded protrusions 20. The two nuts 21 are fixedly connected to the front and rear side walls of the fixed seats 6 respectively. The threaded protrusion 20 positions the fixing block 8 within the rectangular groove 9. When the vehicle body is subjected to force, the fixing block 8 moves smoothly along the rectangular groove 9 under the limiting action of the ball bearing 16 and the strip-shaped arc-shaped slot 17. This causes the fixing block 8 to drive the annular block 23 on the horizontal limiting rod 19 to compress or stretch the two second damping springs 22 under the limiting action of the limiting protrusion 24 and the limiting slot 25, thereby providing damping and buffering for the vehicle body in the horizontal direction and improving the stability and safety of the vehicle body. The second damping springs 22 are fixedly connected to the front and rear inner walls of the strip-shaped groove 18, and the annular block 23 is movably sleeved on the horizontal limiting rod 19. 3. Both second damping springs 22 are sleeved on the horizontal limiting rod 19 and fixedly connected to the front and rear ends of the annular block 23 respectively. The annular sidewall of the annular block 23 is provided with two limiting protrusions 24. The inner walls of the left and right sides of the strip groove 18 are provided with limiting slots 25. The two limiting protrusions 24 are respectively inserted into the two limiting slots 25 and slide against each other. When the limiting protrusions 24 move in the limiting slots 25, they can limit the annular block 23, so that it can move smoothly along the horizontal limiting rod 19 and prevent the inner annular wall of the annular block 23 from pressing against the annular sidewall of the horizontal limiting rod 19. The threaded protrusion 20 and the horizontal limiting rod 19 are integrally cast, and the limiting protrusion 24 and the annular block 23 are integrally cast. The same electromagnetic braking system 26 is fixedly installed between the rear wheel frame 4 and the wheel cover 2. The electromagnetic braking system 26 automatically activates the braking mechanism when parking on a slope, effectively preventing the vehicle from losing control and sliding down the slope due to gravity. It can quickly respond to parking needs, reduce human error, and improve the sense of security and driving confidence when parking on a slope. The electromagnetic braking system 26 is equipped with an adjustable control handle 27, which is used to control the opening or closing of the electromagnetic braking system 26.

[0023] When this utility model is in use, as the intelligent mobility scooter runs with the walking wheels 3, the scooter body, under the force of the fixed seat 6 and the fixed block 8, drives the movable rod 12 to compress the first damping spring 10 and the buffer airbag 11 in the circular groove 7 under the limiting action of the sliding groove 14 and the slider 13. This causes the first damping spring 10 and the buffer airbag 11, together with the movable rod 12 under the limiting action of the sliding groove 14 and the slider 13, to provide vertical damping and buffering for the scooter body. After the scooter body is subjected to force, it drives the fixed block 8 to move within the rectangular groove 9 on the fixed seat 6, causing the fixed block 8 to be forced to move the annular block 23 along... The horizontal limiting rod 19 moves and compresses or stretches the two second damping springs 22, so that the horizontal limiting rod 19 in the strip groove 18, together with the annular block 23 and the second damping springs 22, provides damping and buffering for the vehicle body in the horizontal direction under the limiting action of the limiting protrusion 24 and the limiting slot 25, thereby improving the stability and safety of the vehicle body. The electromagnetic braking system 26 automatically activates the braking mechanism when parking on a slope, effectively preventing the vehicle from losing control and sliding down the slope due to gravity. It can quickly respond to parking needs, reduce human error, and improve the sense of security and driving confidence when parking on a slope.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
