Description
Technical Field
The invention relates to the field of a scooter, in particular to a swing device for the scooter and the scooter.
Background
In a traditional scooter, such as a tricycle, a frame and a rear axle are fixed into a whole, and when the scooter turns (particularly when the scooter turns suddenly), the scooter is influenced by the action of centrifugal force, so that the problems of unbalance and side turning are easy to occur; in particular, the scooter with a smaller rear wheel track is more prone to unbalance and side turning.
In order to solve the problem, some inventors invented a rocker, which connects a frame and a rear axle of an electro-tricycle through the rocker, so that the frame and the front wheels of the electro-tricycle can swing relative to the rear axle, when a vehicle turns, a driver can control the frame and the front wheels to incline towards the inner side of a turning circle, and the centrifugal force of the vehicle when the vehicle turns is counteracted by a component force of gravity of the driver and the frame (component force towards the inner side of a turning radius), or a part of the centrifugal force of the vehicle when the vehicle turns is counteracted, thereby effectively improving the problems that the vehicle is influenced by the centrifugal force and is easy to unbalance and roll over when the vehicle turns (especially when the vehicle turns sharply). At present, although the problem that the vehicle is easy to unbalance and roll over due to the influence of centrifugal force when the vehicle is steered (particularly when the vehicle is steered suddenly) can be solved by the electric tricycle applying the rocker, a driver needs to actively control the front frame to incline towards the inner side of a turn, and the requirement on the driving skill of the driver is high; if the driver does not control the frame and the front wheels to incline towards the turning inner side, the frame can incline towards the turning outer side greatly under the action of centrifugal force on the front frame, and the inclination angle of the frame towards the turning outer side is larger along with the increase of the turning centrifugal force, so that the driver on the frame can incline towards the turning outer side (the driver seat is positioned on the frame), the driving experience of the driver is greatly influenced, fear and uneasiness can be brought to the driver, and even the risk that the driver slides down from the seat can occur; especially for the old person, often difficult control preceding frame toward the inboard slope of turning when the vehicle turns to, can produce people and frame and produce great slope toward the outside of turning together, very big influence driving experience for general old person can't adapt to all.
For example, chinese patent publication No. CN206644925U, published 2017, 11.17.A name invented and created is a rocker of a rocking electric tricycle, which includes a lower shell, an upper shell is disposed above the lower shell to form a rocker shell, a mountain-shaped protrusion is disposed above the upper shell, two sides of a top end of the mountain-shaped protrusion are provided with buffer rubber blocks, a front end of an inner shaft is provided with an outer shaft, the inner shaft is inserted into the rocker shell through a port of the rocker shell, a bearing is disposed between an inner surface of the port of the rocker shell and an outer surface of the inner shaft, a mandrel is disposed at a rear end of the inner shaft, a cross section of the mandrel is cross-shaped, and inner rubber blocks are disposed at four; the aforementioned problems also exist with the rocker of the rocking electric tricycle in this application.
