Description

Technical Field

[0001] The utility model relates to the field of scooters, and specifically relates to a scooter wheel and a scooter with an internal disc brake structure. Background Art

[0002] An electric scooter is a means of transportation based on a traditional manual scooter with an electric power kit added. The control method of an electric scooter is the same as that of a traditional electric bicycle and is easy for a driver to learn. It is equipped with a detachable and foldable seat, and is simpler in structure, smaller in wheel size, lighter and more convenient than a traditional electric bicycle. In recent years, electric scooters have been widely used for short-distance commuting, leisure and entertainment, etc., and have witnessed rapid development. There are mainly two types of braking systems for electric scooters, mechanical braking and electronic braking. Electronic braking utilizes the reverse torque generated by the reverse rotation of the motor to achieve instantaneous braking. Mechanical braking generally uses disc brakes or drum brakes for braking, which are controlled by a manual brake lever. Disc brake braking is relatively safer and more widely used.

[0003] Currently, the disc brake structure of an electric scooter adopts an external arrangement. The disc brake disc and the disc brake caliper are both arranged outside the wheel hub and are directly exposed without protection. On the one hand, the ground clearance of the disc brake disc is usually between 40 - 60 mm, and it is extremely easy to collide with road shoulders, stones, etc., resulting in deformation of the disc brake disc, leading to abnormal or ineffective braking systems. On the other hand, since the disc brake caliper is completely exposed outside due to the complete exposure of the disc brake disc, the arranged position is also completely exposed on the outside and is extremely vulnerable to damage or abnormality due to external forces. Therefore, a new type of disc brake structure is needed to solve the above problems. Summary of the Utility Model

[0004] To solve the above technical problems, the utility model provides a scooter wheel and a scooter with an internal disc brake structure, which can protect the disc brake system, reduce problems such as deformation of the disc brake disc and damage to the disc brake caliper, avoid abnormal or ineffective braking systems caused by accidents, reduce the maintenance of the braking system, and improve the safety performance of the vehicle.

[0005] The technical solution of the utility model is as follows:

[0006] A scooter wheel and a scooter with an internal disc brake structure, comprising a central shaft, a front fork, a wheel hub, a disc brake caliper mounting seat, a disc brake disc, a disc brake caliper, and a connecting member;
