Technical Field

The invention belongs to the technical field of tricycles, and particularly relates to an old-age tricycle with a damping function.

Background

At present, the outdoor activities of the old generally select a near place to go, and if the old needs to go to a far place, the old can drive and ride vehicles, such as: public transport means such as buses and subways, and private transport means such as bicycles, electric tricycles and private cars. For public vehicles, which are all fixed routes, the destination is most likely not on these routes, so private vehicles are a more free choice, where bicycles need to be larger, private cars are more expensive, and electric tricycles are the most suitable.

However, the elderly have relatively weak physical quality, so that the requirements on the damping system of the electric tricycle are relatively high, and particularly, under the condition of poor road conditions, the body of the elderly is greatly burdened, so that the electric tricycle is required to have better damping performance.

One of the shock absorbing performances of the electric tricycle is to improve the shock absorbing effect of the seat.

Disclosure of Invention

The invention mainly solves the technical problem of providing the tricycle for the old people with the damping function, and the tricycle for the old people has a better damping effect and improves the comfort of the old people in the using process by improving the structural design of a tricycle seat.

In order to solve the technical problems, the invention adopts a technical scheme that: a tricycle for the aged with a shock absorption function comprises a tricycle body, a tricycle seat, a backrest, wheels and a handlebar, wherein the tricycle seat comprises an external protective cover and a shock absorption structure positioned in the protective cover;

the shock-absorbing structure comprises an upper shock-absorbing part and a lower shock-absorbing part;

the upper shock absorption piece comprises an upper substrate layer, a first cotton layer formed on the upper surface of the upper substrate layer and a second cotton layer formed on the upper surface of the first cotton layer, the middle of the first cotton layer is inwards sunken to form a groove, and a plurality of negative ion particles are arranged in the groove;

the lower damping part comprises a lower substrate layer, the lower substrate layer is provided with a plurality of positioning holes and a plurality of lower placing holes, and elastic parts are fixed in the positioning holes; the lower surface of the upper substrate layer is provided with a plurality of positioning columns, the positioning columns are matched with the positioning holes, the height of the positioning columns is larger than that of the positioning holes, the lower surface of the upper substrate layer is provided with a plurality of upper placing holes, when the upper damping part and the lower damping part are spliced through the positioning columns and the positioning holes, the upper placing holes and the lower placing holes form accommodating cavities for accommodating buffer rubber balls, and a certain gap is reserved between the upper damping part and the lower damping part when no external pressure exists;

the lower surface of the upper substrate layer is distributed with at least one first magnet, the upper surface of the lower substrate layer is distributed with at least one second magnet, and the upper substrate layer and the lower substrate layer are attracted by the first magnet and the second magnet.

The invention adopts a further technical scheme for solving the technical problems that:

further, the protective cover is a leather protective cover.

Further, the first surface layer is a high-density memory cotton layer.

Further, the second cotton layer is a low-density memory cotton layer.

Furthermore, one side of the protective cover is provided with a zipper.

Further, the buffer rubber ball is oval.

Further, the upper substrate layer, the first cotton layer and the second cotton layer are connected through an adhesive.

Further, the height direction of the elastic piece is consistent with the height direction of the positioning hole.

Further, the positioning holes are formed at four corners of the lower substrate layer.

Further, the lower placing holes are distributed at intervals along the length direction of the lower substrate layer.

The invention has the beneficial effects that: the saddle comprises an external protective cover and a shock-absorbing structure positioned in the protective cover, wherein when no external pressure exists in the shock-absorbing structure, a certain gap is formed between an upper shock-absorbing part and a lower shock-absorbing part; when the external pressure is applied, the buffering rubber ball between the upper shock absorption part and the lower shock absorption part and the elastic part between the positioning hole and the positioning column play a role in shock absorption, the resetting speed of the upper shock absorption part can be reduced by the buffering rubber ball, the shock absorption effect is further played, and the comfort level of the buttocks of a user can be improved even in a bumpy road condition;

the upper damping part and the lower damping part are movably connected, and when the buffering rubber ball between the upper damping part and the lower damping part is deformed and loses elasticity due to long-term use, the buffering rubber ball is convenient to replace in time, and the service life of the saddle is prolonged.
