Description
Technical field
The utility model belongs to technical field of medical instruments, and in particular to wheelchair special purpose spring damping device.
Background technology
Electric wheelchair is mainly used in the wheel-chair by driven by power, can advance, retreats and turn, and outer indoors can make
With operating easy and convenient.
Electric wheelchair in the market is universal, and as not ground is jolted injustice when outgoing, user needs special controls
Travel speed, with falling-resistant, it is necessary to there is household to accompany with the coefficient that ensures safety.
Utility model content
Purpose of utility model：The purpose of this utility model is to provide wheelchair special purpose spring damping device, apparatus structure letter
Single compact, damping is comfortable, meets user's demand.
Technical scheme：In order to realize above-mentioned purpose of utility model, the utility model adopts the following technical scheme that：
Wheelchair special purpose spring damping device, including back rest, seat frame and damping spring, the both ends of described back rest are equal
It is fixed on respectively by column on seat frame；Two damping springs, described damping spring are symmetrical arranged on described column
One end be fixedly installed on column, the other end of described damping spring is connected by connecting rod piece with seat frame.
The other end of described damping spring is connected by standing screw with connecting rod piece.
The both ends of described back rest are rotatedly connected with column.
Described back rest is U-shaped.
Described back rest is arranged on electric wheelchair.
Beneficial effect：Wheelchair special purpose spring damping device of the present utility model, when user meets bumpy sections, seat frame
Vibrations damping spring is transferred to by connecting rod piece, buffering is realized by the compression of damping spring, and then realize damping；The present apparatus
It is simple and compact for structure, it is improved using existing apparatus on wheelchair and the purpose of this utility model can be achieved, beneficial to popularization and application,
Possesses good economic benefit.
Brief description of the drawings
Fig. 1 is the Wheelchair structure schematic diagram with wheelchair special purpose spring damping device；
Fig. 2 is the structural representation of wheelchair special purpose spring damping device；
Fig. 3 is damping spring enlarged diagram.
Embodiment
The utility model is further described below in conjunction with the accompanying drawings.
As shown in figure 1, the wheelchair with wheelchair special purpose spring damping device, including back rest 1, seat frame 2, control stick 3,
Handrail 4, pedal 5, universal wheel front fork 6, universal wheel 7, damping spring 8, motor driving wheel 9, lithium battery 10, controller 11 and gear
Mud plate 12.Back rest 1, seat frame 2 and handrail 4 constitute the framework of wheelchair, and the pedal being used cooperatively is set under the framework
5th, universal wheel front fork 6, universal wheel 7 and motor driving 9, electronic lithium battery 10 and controller 11 are set in the bottom of the framework.
Mud guard 12 is set on motor driving wheel 9.Damping spring 8 is set on back rest 1.
As Figure 2-3, back rest 1 is U-shaped, and the both ends of the U-shaped of back rest 1 are respectively fixed on seat cushion by column 13
On frame 2, both ends and the column 13 of the U-shaped of back rest 1 are rotatedly connected.Two damping springs 8, damping are symmetrical arranged on column 13
One end of spring 8 is fixedly installed on column 13, and the other end of damping spring 8 is connected by connecting rod piece 14 with seat frame 2.Damping
The other end of spring 8 is connected by standing screw 15 with connecting rod piece 14.
The course of work：When user meets bumpy sections, the vibrations of seat frame 2 are transferred to damping spring by connecting rod piece 14
8, buffering is realized by the compression of damping spring 8, and then realize damping；Damping spring 8 lives seat cushion using elasticity stable, so that
Drivers will not jolt because of road conditions.Such magnesium alloy intelligent electric wheelchair, manual and electric free switching, overturns tradition, on the right side
Rear wheel-side has spring vibration damper, when meeting the bad road surface of road conditions on the way wheelchair vibrations of jolting may be significantly alleviation, immediately
The comfortable safety coefficient of user is improved, goes on a journey alone not and hidden danger be present.
