When a double rear wheel drive scooter is turning, the turning radius of the outer rear wheel is greater than that of the inner rear wheel. Therefore, the existing dual rear wheel drive scooter usually needs to adjust the inner and outer rear wheels by means of a differential. The speed difference is to make the speed of the outer wheel higher than the speed of the inner wheel, so that the inner and outer rear wheels can turn smoothly without interfering with each other. However, due to the complex structure and high cost of the differential, resulting in double rear wheels Wheel-drive scooters have the problems of complex structure and high cost; while the existing single front-wheel drive scooters are prone to head tilt during driving, and have a low safety factor. Therefore, the existing dual rear-wheel drive or Single front-wheel drive scooters cannot meet the actual needs of current users

Embodiment Construction
[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0033] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relationship between the components in a certain posture (as shown in the accompanying drawings). Relative positional relationship, movement conditions, etc., if the specific posture changes, the directional indication will also change accordingly. In addition, the descripti...

The invention discloses a scooter. The scooter comprises a scooter body, a front wheel, a first rear wheel, a second rear wheel, a driving part and a controller, wherein the front wheel is rotationally arranged on a front portion of the scooter body, the first rear wheel and the second rear wheel are rotationally arranged on a rear portion of the scooter body at intervals, the driving part is connected with the first rear wheel, and the quantity of the driving part is one. According to the scooter, the number of the driving part is one, the driving part is only used for driving the first rear wheel to rotate so as to drive the scooter body to move, the controller is electrically connected with the driving part, and the controller is used for adjusting the rotating speed of the driving part so as to adjust the rotating speed of the first rear wheel. The scooter driven by the single rear wheel does not need a differential mechanism with a complex structure like a scooter driven by double rear wheels in the prior art, and also does not need a scooter driven by a single front wheel in the prior art, and therefore the scooter is simple in structure, low in cost and high in safety coefficient.
Description
technical field [0001] The invention relates to the technical field of walking aids, in particular to a scooter. Background technique [0002] Existing scooter usually adopts double rear wheel drive or single front wheel drive. When a double rear wheel drive scooter is turning, the turning radius of the outer rear wheel is greater than that of the inner rear wheel. Therefore, the existing dual rear wheel drive scooter usually needs to adjust the inner and outer rear wheels by means of a differential. The speed difference is to make the speed of the outer wheel higher than that of the inner wheel, so that the inner and outer rear wheels can turn smoothly without interfering with each other. However, due to the complex structure and high cost of the differential, resulting in double rear wheels The wheel-driven scooter has the problems of complex structure and high cost; while the existing single front-wheel drive scooter is prone to head tilt during driving, and has a low sa...
