Being provided for of joystick makes the wheelchair occupant rotate joystick, thereby two front-wheels of actuator drives rotate and drive wheelchair and move ahead.
For example, two joysticks that turn clockwise simultaneously, wheelchair advances; When wheelchair need be turned left, the joystick in left side stopped operating, the joystick on the right side that turns clockwise, and then wheelchair is realized the operation of turning left.When wheelchair need be retreated, be rotated counterclockwise joystick simultaneously.Joystick is arranged at the seat front portion, controls advancing of wheelchair, turns to, and retreats very conveniently, and wholesomeness is good, and transmission efficiency is high.
As preferably, said actuating device comprises the driven gear that is meshed on the wheel shaft of the taper driven wheel of being located at the joystick lower end and front-wheel.The actuating device that driven wheel and driven gear are formed has controls easily the characteristics that transmission efficiency is high.
As preferably, said crank comprises handle and pivoted arm, and handle is connected through rotating shaft with pivoted arm.In the time of need shaking joystick handle opened and make itself and the rectangular steady statue of pivoted arm; In the time need not shaking joystick, handle and pivoted arm are folded.
As preferably, pivoted arm is the telescopic sleeve pipe structure.The telescopic sleeve pipe structure makes the length of pivoted arm to regulate, and pivoted arm is long more laborsaving more, can regulate according to occupant's needs.
As preferably, said crank is provided with the crank medicated cap, and the crank cap sleeve is in the joystick upper end, and the crank medicated cap is provided with through hole, and joystick is provided with corresponding convexity.When needs shake wind and drive wheelchair and move ahead, the convexity on the joystick is passed the through hole on the crank medicated cap, shake crank this moment and drive wheelchair and advance.In the time need not shaking wind and drive wheelchair and move ahead, the convexity on the joystick is broken away from the through hole on the crank medicated cap, crank medicated cap and joystick are gapped socket, wheel can not drive the crank rotation.
As preferably, said trailing wheel is a universal wheel.Trailing wheel is a universal wheel, and wheelchair rotates more flexible.
As preferably, said joystick is provided with braking clamp, and braking clamp is connected with the brake cable upper end, the brake cable lower end respectively with the wheel hub that is arranged on left and right front-wheel on disc brake apparatus be connected.The braking that is provided for controlling respectively two front-wheels of braking clamp, brake cable and disc brake apparatus, this design operation is simple and convenient, can in time control the motion of front vehicle wheel, effectively avoids wheel chair sport danger out of control to occur.Disc brake apparatus comprises disc brake sheet and disc brake.It is good that disc brake apparatus has a braking quality, the characteristics of processing ease.
As preferably, be provided with damping spring between vehicle frame and front-wheel, the trailing wheel.The setting of damping spring has alleviated the influence of the vibrations of wheelchair to the occupant, takes more comfortable.
As preferably, the foot carriage of vehicle frame is provided with detachable foot holder.Upper and lower wheelchair is conveniently taken in the foot holder, also can be used to place the foot of taking the people, need not be placed in the foot holder if take people's foot, then can the foot holder be disassembled, and perhaps is fixed to suitable position according to taking human needs.
As preferably, the seat both sides are provided with protects the skirt net.Protect the skirt net and can prevent effectively that medicated clothing from clipping in the wheel, and aeration is good.
Therefore, the utlity model has following beneficial effect: it is convenient that wheelchair is controlled in (1); (2) can damping.
Description of drawings
Fig. 1 is a kind of structural representation of this utility model.
Among the figure: front-wheel 1, vehicle frame 2, handle 3, driven wheel 5, driven gear 6, pivoted arm 7, joystick 8, foot carriage 9, seat 10, crank medicated cap 11.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment this utility model is done further description.
Embodiment as shown in Figure 1 is a kind of wheelchair of conveniently controlling; Comprise: vehicle frame 2, be located at seat 10 on the vehicle frame, be located at the vehicle frame rear portion trailing wheel, be located at two front-wheels 1 of the front axle both sides of vehicle frame; Also comprise and be located at forward two the rotating joysticks 8 of seat vertically; Two joystick upper ends are respectively equipped with crank, and rotate through two front-wheels of actuator drives respectively the lower end of two joysticks.Said actuating device comprises the driven gear that is meshed 6 on the wheel shaft of the taper driven wheel 5 of being located at the joystick lower end and front-wheel.Said crank comprises handle 3 and pivoted arm 7, and handle is connected through rotating shaft with pivoted arm.Pivoted arm is the telescopic sleeve pipe structure.Said crank is provided with crank medicated cap 11, and the crank cap sleeve is in the joystick upper end, and the crank medicated cap is provided with through hole, and joystick is provided with corresponding convexity.Said trailing wheel is a universal wheel.Said joystick is provided with braking clamp, and braking clamp and brake cable upper end is connected, the brake cable lower end respectively with the wheel hub that is arranged on left and right front-wheel on disc brake apparatus be connected.Disc brake apparatus comprises disc brake sheet and disc brake.Be provided with damping spring between vehicle frame and front-wheel, the trailing wheel.The foot carriage 9 of vehicle frame is provided with detachable foot holder.The seat both sides are provided with protects the skirt net.Said handle and pivoted arm are the industrial plastic material.
