Abstract
A buffering and damping mechanism of a walking air wheelchair comprises a frame (1), a seat (2), a damping device (3), rear wheels (4) and front wheels (6), wherein the damping device (3) is composed of a damper (12) and a damping spring (11) and disposed between the wheelchair front wheels (6) and the frame (1). The mechanism is characterized in that the upper end and the lower end of the damping spring (11) are fixed on an upper supporting plate (10) and a lower supporting plate (13) of the damper (12) respectively; a hydraulic system with a buffering function is disposed inside the damper (12); and threads (9) and threads (14) are disposed on the upper part and the lower part of the damper (12). According to the invention, the structure is simple; manufacture cost is low; jolting and shaking ranges of the wheelchair can be effectively reduced during walking; and the mechanism is characterized by high safety, high comfort and convenient carrying, etc.
Description
Technical field
The invention belongs to medical instruments field, particularly a kind of damping of walking-aided wheelchair buffering.
Background technology
Walking-aided wheelchair is used as medical special equipment, and its function sets service object as specific crowd or old people, 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 by wheelchair and participate in
Social activity.At present, although existing wheelchair solves the problems, such as trip on the market, but its riding comfort need to be improved.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 buffers shock-absorbing, and wheelchair can be made to jolt incessantly, and riding comfort is substantially reduced, or even inclination is translated into, and causes user to be received
, there is certain potential safety hazard in wound.
Content of the invention
For the deficiencies in the prior art, it is an object of the invention to provide a kind of walking-aided wheelchair with bumper and absorbing shock, be
Between walking-aided wheelchair front-wheel and vehicle frame, damping device is set, is prevented effectively from walking-aided wheelchair and occurs when walking jolting, use
Person becomes comfortable safety in trip.
The technical solution adopted in the present invention：A kind of walking-aided wheelchair damping, including vehicle frame, seat, front-wheel, trailing wheel,
Damping device, it is characterised in that：Damping device is set between the wheelchair front wheel with vehicle frame；The damping device by amortisseur with
Shock-absorbing spring constitutes, and the damping spring top and bottom are separately fixed at upper bearing plate and the lower support plate of amortisseur；Described
The effect that hydraulic system has buffering is provided with amortisseur, and the damping spring has the effect of shock-absorbing, on the amortisseur
Portion and bottom offer screw thread.
The amortisseur is through inside damping spring, i.e., the amortisseur is used in parallel with shock-absorbing spring.
The amortisseur is to enter row buffering using hydraulic pressure, carries out shock-absorbing by the compression of the damping spring and recovery.
The damping device is that vehicle frame and front-wheel connecting lever are distinguished in the upper and lower of amortisseur by the mode that is threaded connection
Fixing.
The present invention, simple structure, damping device is set between wheelchair front wheel and vehicle frame, runs into injustice or road surface of jolting
When, the vibrations from ground can be relaxed well and in time vibration energy is carried out absorption mitigation, effectively reduce wheelchair in walking
When jolt, jitter amplitude, with safety and comfort are used, the features such as carry convenient.
Description of the drawings
Fig. 1 is the structural representation of the present invention；
Fig. 2 is damping device system schematic of the present invention；
Fig. 3 is shock absorber structure schematic diagram of the present invention；
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 subtract
Shake device top screw thread, 10 amortisseur upper bearing plates, 11 damping springs, 12 amortisseurs, 13 amortisseur lower support plate, under 14 vibroshocks
Portion's screw thread.
Specific embodiment
Known by Fig. 1, a kind of walking-aided wheelchair buffer damping mechanism of the present invention, including vehicle frame 1, seat 2, front-wheel 6, trailing wheel 4, subtract
Shake device 3, damping device 3 is located at wheelchair front wheel connecting lever 5 and is arranged with the vehicle frame 1 of seat lower end.
Known by Fig. 2, the vibration absorber upper and lower offers screw thread, is threaded connection mode by the upper of amortisseur
Portion and bottom respectively above the lower section screwed hole 7 of seat lower end vehicle frame and front-wheel connecting lever screwed hole 8 fix.
Known by Fig. 3, the damping device 3 is made up of amortisseur 12 and damping spring 11, the amortisseur 12 passes through damping
Inside spring 11,11 top and bottom of the damping spring are separately fixed at the upper bearing plate 10 of amortisseur and lower support plate 11；
The effect that hydraulic system has buffering, effect of the damping spring 11 with shock-absorbing is provided with the amortisseur 12；Walk help
When wheelchair runs into uneven road surface, vibration energy is delivered to damping device 3 through front-wheel connecting lever 5, and vibration energy is by 12 liquid of amortisseur
Pressure Systemic absorption, damping spring 11 is relaxed 12 hydraulic pressure system of amortisseur also with compressing after damping spring 11 recovers elastic deformation
The vibration energy that system absorbs, therefore the amortisseur 12 is used in parallel with shock-absorbing spring 11.
