Abstract
A kind of walking-aided wheelchair buffer damping mechanism, including vehicle frame（1）, seat（2）, damping device（3）, trailing wheel（4）, front-wheel（6）, described damping device（3）By damper（12）And damping spring（11）Composition, is arranged on wheelchair front wheel（6）With vehicle frame（1）Between；It is characterized in that：Described damping spring（11）Top and bottom be separately fixed at damper（12）Upper bearing plate（10）And lower support plate（13）On；The damper（12）Inside it is provided with the hydraulic system with cushioning effect, the damper（12）Top, bottom shock absorber top screw thread（9）With shock absorber lower thread（14）.The utility model, simple in construction, low manufacture cost, effectively reduction wheelchair are jolted when walking, jitter amplitude, with using safety and comfort, the features such as carrying convenient.
Description
Technical field
The utility model belongs to medical instruments field, particularly a kind of damping of walking-aided wheelchair buffering.
Background technology
Walking-aided wheelchair is as medical special equipment, and its function sets service object as specific crowd or the elderly, especially
It is that it is not only a kind of walking-replacing tool for handicapped people comes, more importantly can goes on a journey and participate in by wheelchair
Social activities.At present, although existing wheelchair solves the problems, such as trip on the market, but its riding comfort need to be improved.It is existing
Due to being not provided with damping device on the front-wheel of traditional wheelchair, wheelchair ought run into uneven road surface or surface conditions are poor
Shi Wufa buffer shock-absorbing, wheelchair can be made to jolt incessantly, riding comfort is substantially reduced, in addition inclination translate into, cause user by
, there is certain potential safety hazard in wound.
The content of the invention
In view of the shortcomings of the prior art, the purpose of this utility model is to provide a kind of walking-aided wheelchair with bumper and absorbing shock,
It is that damping device is set between walking-aided wheelchair front-wheel and vehicle frame, is prevented effectively from walking-aided wheelchair and jolts when walking, make
User becomes comfortable safety in trip.
The technical scheme that the utility model is used：A kind of walking-aided wheelchair damping, including vehicle frame, seat, front-wheel, after
Wheel, damping device, it is characterised in that：Damping device is set between the wheelchair front wheel and vehicle frame；The damping device is by damping
Device is constituted with shock-absorbing spring, and the damping spring top and bottom are separately fixed at the upper bearing plate and lower support plate of damper；
Hydraulic system is provided with the damper has the effect of buffering, and the damping spring has the effect of shock-absorbing, the damping
Device upper and lower part offers screw thread.
The damper is passed through inside damping spring, i.e., described damper is used in parallel with shock-absorbing spring.
The damper is to enter row buffering using hydraulic pressure, and shock-absorbing is carried out with recovering by the compression of the damping spring.
The damping device is that vehicle frame and front-wheel connecting lever are distinguished in the upper and lower part of damper by the mode that is connected through a screw thread
It is fixed.
The utility model, it is simple in construction, damping device is set between wheelchair front wheel and vehicle frame, runs into uneven or jolts
During road surface, the vibrations from ground can be relaxed well and vibration energy is subjected to absorption mitigation in time, effectively reduction wheelchair exists
Jolted during walking, jitter amplitude, with using safety and comfort, the features such as carrying convenient.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the utility model damping device system schematic；
Fig. 3 is the utility model shock absorber structure schematic diagram；
In figure：1 vehicle frame, 2 seats, 3 damping devices, 4 trailing wheels, 5 connecting levers, 6 front-wheels, 7 vehicle frame screwed holes, 8 connecting lever screwed holes,
9 shock absorber top screw threads, 10 damper upper bearing plates, 11 damping springs, 12 dampers, 13 damper lower support plates, 14 vibration dampings
Device lower thread.
Embodiment
Known by Fig. 1, a kind of walking-aided wheelchair buffer damping mechanism of the utility model, including vehicle frame 1, seat 2, front-wheel 6, trailing wheel
4th, damping device 3, damping device 3 is located at wheelchair front wheel connecting lever 5 and the vehicle frame 1 of seat lower end is set.
Known by Fig. 2, the vibration absorber upper and lower part offers screw thread, is connected through a screw thread mode by the upper of damper
Portion and bottom are distinguished screwed hole 8 above the lower section screwed hole 7 and front-wheel connecting lever of seat lower end vehicle frame and fixed.
Known by Fig. 3, the damping device 3 is made up of damper 12 and damping spring 11, the damper 12 passes through damping
Inside spring 11, the top and bottom of damping spring 11 are separately fixed at the upper bearing plate 10 and lower support plate 11 of damper；
Hydraulic system is provided with the damper 12 has the effect of buffering, and the damping spring 11 has the effect of shock-absorbing；Walk help
When wheelchair runs into uneven road surface, vibration energy is delivered to damping device 3 by front-wheel connecting lever 5, and vibration energy is by the liquid of damper 12
Pressure system absorbs, and damping spring 11 is also with being compressed, and damping spring 11 recovers after elastic deformation, relaxes the hydraulic pressure system of damper 12
The vibration energy that system absorbs, therefore the damper 12 and shock-absorbing spring 11 are used in parallel.
