Description
Technical field
The utility model relates to the technical field of mobility scooter for old people, is specifically related to a kind of shock-absorbing seat for mobility scooter for old people.
Background technology
Along with the development of society, the raising of people's living standard, the elderly and disabled person also get more and more and use scooter as the vehicle, greatly reduce the inconvenience of elderly and the disabled's trip, but because elderly and the disabled's fitness is relatively weak, this just requires relatively high to the shock mitigation system of scooter, existing scooter shock mitigation system damping effect is not ideal, when particularly road conditions are bad, comparatively large to the body burden of the elderly and the disabled, and damper of vehicle except tire be exactly that seat is the most important.
Summary of the invention
Technical problem to be solved in the utility model is, a kind of shock-absorbing seat for mobility scooter for old people provided, and structure is simple, good damping effect.
For achieving the above object, the technical scheme that the utility model is taked is:
A kind of shock-absorbing seat for mobility scooter for old people, comprise main body, it is characterized in that: described bottom part body is provided with at least 4 Shock absorbers, described Shock absorber comprises the outer tube of tubular, be located at the capping on outer tube top, through capping center through hole and the piston rod goed deep in outer tube, be located at the piston head of piston rod bottom, outer tube internal cavity is divided into upper plenum and lower cavity by this piston head, spring is provided with in described lower cavity, described outer tube upper end wall is provided with from outer toward interior check valve one, middle part is provided with blow off valve, described piston head is provided with check valve two from top to bottom, survey in described outer tube top and be provided with seal groove, described seal groove is provided with seal ring.
As preferably, described Shock absorber upper end is fixed on bottom part body by attaching parts, and lower end is fixed on scooter vehicle frame by permanent seat.
As preferably, described blow off valve is from interior unidirectional outward, and it opens required pressure higher than check valve two.
As preferably, when described piston head up moves, highly check valve one can not be exceeded.
As preferably, described spring upper end and piston head contact connection, and lower end and outer tube inner bottom surface contact connection.
A kind of shock-absorbing seat for mobility scooter for old people described in the utility model, compensate for the deficiencies in the prior art, adopts multiple pneumatic bumper, in conjunction with spring, reaches good damping effect, and structure is simple, and cost is low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of Shock absorber in the utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing and example, the utility model is described further.
As shown in the figure, a kind of shock-absorbing seat for mobility scooter for old people, comprise main body 1, it is characterized in that: bottom described main body 1, be provided with at least 4 Shock absorbers 3, described Shock absorber 3 comprises the outer tube 305 of tubular, be located at the capping 313 on outer tube 305 top, through capping 313 center through hole and the piston rod 303 goed deep in outer tube 305, be located at the piston head 306 of piston rod 303 bottom, outer tube 305 internal cavity is divided into upper plenum 304 and lower cavity 307 by this piston head 306, spring 308 is provided with in described lower cavity 307, described outer tube 305 upper end wall is provided with from outer toward interior check valve 1, middle part is provided with blow off valve 311, described piston head 306 is provided with check valve 2 310 from top to bottom, survey in described outer tube 305 top and be provided with seal groove 302, described seal groove 302 is provided with seal ring 301, described Shock absorber 3 upper end is fixed on bottom main body 1 by attaching parts 2, lower end is fixed on scooter vehicle frame by permanent seat 4, described blow off valve 311 is from interior unidirectional outward, it opens required pressure higher than check valve 2 310, when described piston head 306 up moves, height can not exceed check valve 1, described spring 308 upper end and piston head 306 contact connection, lower end and outer tube 305 inner bottom surface contact connection.
When piston head 306 moves downward, extraneous air enters upper plenum 304 from check valve 1, when piston head 306 upward movement, open required pressure due to blow off valve 311 and be greater than check valve 2 310, therefore check valve 2 310 is first opened, air in upper plenum 304 preferentially enters lower cavity 307 from check valve 2 310, and the air pressure instantly in cavity 307 increases to and enough opens blow off valve 311, when piston head 306 is in again above blow off valve 311, air in lower cavity 307 can be discharged by blow off valve 311, this ensures that there piston head 306 to be in blow off valve about 311 all the time and can not to cross high pressure and do not get off, outer tube 305 top is provided with seal ring 301, and adopt capping 313 to compress, ensure that good leak tightness, spring 308 is provided with in lower cavity 307, ensure while playing damping effect further that piston head 306 can not strike outer pipe bottom and damage.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., be all included within protection domain of the present utility model.
