Abstract
The invention relates to the technical field of wheelchairs, in particular to a front fork for an electric wheelchair with a shock-absorbing device. The front fork for the electric wheelchair with the shock-absorbing device comprises a vertical shaft, a fork base, a spring sleeve, a fastening bolt, a gasket, a first screw, a second screw, a first screw nut, a second screw nut and a fork foot plate. A spring is arranged in the front fork of the electric wheelchair with the shock-absorbing device, and the spring can effectively reduce bumpiness, caused by an uneven road surface, of a user sitting on the electric wheelchair, so that the user feels more comfortable. When the front fork is used, when a person sits on the electric wheelchair or the electric wheel bumps, the first screw will move in a U-shaped groove, so that the spring is driven to deform to achieve a bumpiness buffering function, and the user feels more comfortable. Besides, the front fork for the electric wheelchair with the shock-absorbing device is reasonable in design, stable and reliable in use and suitable for application and popularization.
Description
Technical field
The present invention relates to wheelchair technical field, particularly relate to a kind of electric wheelchair front fork with damping device.
Background technology
Electric wheelchair improves on the basis of traditional manual wheelchair, and add critical pieces such as loading onto high performance driving device, Intelligent control device, battery, transformation and upgrade form.Common electric wheelchair, user only needs to manipulate stick just can realize the functions such as the advance of wheelchair, retrogressing, turning and stopping.Great help can be provided to individuals with disabilities or action inconvenient personage.But common electric wheelchair lacks damping device, be expert at and go to the section of Uneven road, can bring to the people taking electric wheelchair and jolt, affect the comfort level of electric wheelchair occupant.
The present invention devises a kind of electric wheelchair front fork with damping device, is provided with spring in this electric wheelchair front fork, and what spring effectively can reduce that Uneven road causes take electric wheelchair person jolts, and makes occupant more comfortable.This front fork in use when people takes electric wheelchair or run into jolt time, screw moves for a moment in U-lag, thus drive spring generation deformation, play the effect cushioning and jolt, make occupant more comfortable, in addition the electric wheelchair front fork structure of this band damping device is reasonable in design, uses reliable and stable, is applicable to promoting the use of.
Summary of the invention
In order to overcome the defect existed in background technology, the technical solution adopted for the present invention to solve the technical problems is: a kind of electric wheelchair front fork with damping device, comprise vertical shaft, forked standard, spring housing, hanging bolt, packing ring, screw one, screw two, screw one nut, screw two nut and fork foot plate, described vertical shaft is arranged on the top of forked standard, be together by a threaded connection between described vertical shaft and forked standard, the outside of described vertical shaft is provided with vertical shaft hold-down nut, spring housing is provided with in described forked standard, spring is provided with in described spring housing, the bottom of described spring housing is provided with U-lag, described hanging bolt passes in spring and U-lag, sole is movable links together by forked standard and fork for described screw two and screw two nut, two fork soles are fixed together by described screw one and screw one nut, described screw one passes from one end of hanging bolt, another one end of described hanging bolt is provided with hanging bolt hold-down nut, packing ring is provided with between described spring and hanging bolt hold-down nut.
A kind of electric wheelchair front fork with damping device involved in the present invention, is provided with spring in this electric wheelchair front fork, and what spring effectively can reduce that Uneven road causes take electric wheelchair person jolts, and makes occupant more comfortable.This front fork in use when people takes electric wheelchair or run into jolt time, screw moves for a moment in U-lag, thus drive spring generation deformation, play the effect cushioning and jolt, make occupant more comfortable, in addition the electric wheelchair front fork structure of this band damping device is reasonable in design, uses reliable and stable, is applicable to promoting the use of.
