Automatic foot support device

Abstract

The invention provides an automatic kickstand device comprising a drive motor, a worm gear transmission component, a transmission shaft and hoops. The automatic kickstand device is characterized in that the automatic kickstand device further comprises limiting components, first support tubes, second support tubes, crank connecting rod components and a circuit device; when an electric bicycle or a motorcycle is in a pushing or riding state, the first support tubes, the second support tubes and the crank connecting rod components are in an initial state; when parking is needed, the circuit device controls the drive motor to work, and through the worm gear transmission component, the transmission shaft and the crank connecting rod components, the drive motor enables the second support tubes and the first support tubes to rotate forwardly to limiting blocks to be limited; afterwards, the second support tubes slide downwardly to prop up the rear portion of the electric bicycle or the motorcycle by the aid of the first support tubes, the limiting components send out signals to control the drive motor to stop through the circuit device after in-place propping, and automatic kickstand action is completed. The automatic kickstand device is simple and compact in structure, small in size, easy to mount, high in transmission efficiency, low in power consumption and long in service life.

Description

technical field [0001] The invention relates to a supporting device for an electric vehicle or a motorcycle, in particular to an automatic foot supporting device. Background technique [0002] Common electric car or the kicker device of motorcycle generally have the extension spring diagonal brace that temporarily suspends usefulness and the big brace that park usefulness. When the common large support feet for parking are in use, manpower is required to grasp the rear of the car to lift the rear wheels, and then step on the large support feet to realize parking support. However, in the case of electric vehicles or motorcycles with heavy self-weight or heavy vehicle load, it is more laborious to support the vehicle with such a large support foot, especially for weak women and other crowds. [0003] In order to solve this problem, people start to adopt the automatic double foot support device driven by motors on electric vehicles or motorcycles. For example, the Chinese pat...

Problems solved by technology

For example, the Chinese patent document with the publication number CN 102923210A discloses a kind of electric double support foot that adopts motor drive, screw rod and gear transmission structure, which can realize automatic support, but the disadvantage is that the screw rod and gear transmission Higher power motors are required, the transmission efficiency is not good and the service life is limited; another example is the Chinese patent document with the publication number CN 103818496A, which discloses another electric double support using screw drive; another example is the authorized announcement No. The Chinese patent literature of CN 204037728U discloses a kind of electric double support foot that adopts screw rod transmission

It can be seen that the automatic double support devices currently used on electric vehicles or motorcycles usually use screw drive devices. The common problems are that the structure is relatively complicated, the volume is large, the installation is inconvenient, the power consumption is large, and the service life is limited. There is a lot of noise during use
