Description

Electric wheel-chair vehicle

Technical field

This utility model relates to a kind of people with disability, patient's device instead of walk, especially a kind of electric wheel-chair vehicle.

Background technology

Existing people with disability, patient's equipment of riding instead of walk adopt the wheel Wheel-chair more, its power mode is following three kinds substantially: 1, manual type, and the type car is realized the motion of car body by rotating the other rim of two-wheeled manually, adopts this kind mode effort of travelling, and speed is slow, therefore should not go hiking; 2, hand chain-type, though this mode is laborsaving than 1 mode, speed has raising, is not suitable for long journey equally; 3, motorcycle, electrodynamic type, this mode can overcome the shortcoming of above-mentioned dual mode effectively, and is laborsaving, speed is fast, but himself complex structure and cost height.Though more than several Wheel-chairs of taking turns can ride instead of walk for the people with disability, can't solve the people with disability and solve separately a large and small difficult problem just.

The utility model content

The technical problems to be solved in the utility model provides a kind of people with disability separately can large and small electric wheel-chair vehicle just.

For solving the problems of the technologies described above, this utility model is to be provided with wheel and seat support on underframe, the accumulator that is positioned on the underframe drives the motor rotation by the control speed regulator, motor drives wheel by actuating device and rotates, described seat support is to put on the shelf at the chair frame to be provided with mobilizable base, be respectively equipped with suspension rod moving up and down in the both sides of chair frame, between two suspension rods, be connected with a suspender belt; On the chair frame, be provided with and drive the elevating mechanism that suspension rod moves up and down; Bottom at base is placed with chamber pot.

This utility model drives suspension rod by elevating mechanism and rises in use, and the suspension rod of rising drives on the suspender belt and moves, and the suspender belt that moves on like this gets final product pull-up and is sitting in user on the base; After user rising certain height, active base can be taken out, expose the chamber pot that is positioned at the base bottom, user can carry out defecation.After the convenient end of user, active base is reapposed on the chair frame, by elevating mechanism suspension rod, suspender belt is moved down then, user can be sitting on the seat support again, rides instead of walk.

Adopt the beneficial effect that technique scheme produced to be: user (people with disability, patient) uses this utility model not need to get off can carry out conveniently (defecation), solve the people with disability goes the lavatory inconvenience under the situation that does not have other people to help a difficult problem, used convenient, safety.

The specific embodiment

As shown in Figure 1, this electric wheel-chair vehicle is provided with wheel and seat support on underframe, and 14 and the turning to of steering 11 these electric wheel-chair vehicles of realization, front truck can be provided with brake 15 to Herba Plantaginis wheel 12 on 14 by front truck.Be provided with accumulator 13 on underframe, accumulator 13 drives motor 10 by the control speed regulator and rotates, and motor 10 drives rear wheel 8 by chain 9 and rotates, and chain also can be other actuating devices such as belt, V-belt.Side at seat support is provided with control 3, and control is being provided with another brake 20.Be provided with on the pro-handlebar 14 with what can place article and make things convenient for plate 16 or convenient stand.

As Fig. 1, shown in Figure 3, the seat support of this electric wheel-chair vehicle is to put on the shelf at chair frame 1 to be provided with mobilizable base 18, and base 18 is connected with the upper end of chair frame 1 by connecting rope 34, like this when user is conveniently removed base 18, base can not drop, thereby increases the ease of use of this electric wheel-chair vehicle.This electric wheel-chair vehicle is respectively equipped with the suspension rod 4 moving up and down and the chair back 2 in the both sides of chair frame 1, promptly the chair back 2 is socketed on the chair frame 1, and the two ends of the chair back 2 are connected with suspension rod 4.Between two suspension rods, be connected with a suspender belt 22, be placed with chamber pot 17 in the bottom of base 18.

As shown in Figure 1, 2, 3, this electric wheel-chair vehicle is provided with on chair frame 1 can drive the elevating mechanism that suspension rod 4 moves up and down, elevating mechanism can adopt motor elevating mechanism, hydraulicefficiency elevation structure etc., also can adopt the elevating mechanism of following structure: on chair frame 1, be rotatably connected to columniform bull stick 5, be consolidated with halliard 21 on the bull stick 5, halliard 21 passes fixed pulley 35 backs that are located on the chair frame 1 and is connected with suspension rod 4.Be connected with and the concentric gear 7 of bull stick in the end of bull stick 5, on chair frame 1, be provided with the rotation of lifting handle 6 driven gears 7.The middle part of piped handle shell 23 front ends of lifting handle has groove and forms U-lag, and two ends 33 of U-lag are positioned at the both sides, front and back of gear 7 and are rotatably connected on the bull stick 5; Switching has driving lever 26 in U-lag, the turning cylinder 25 of driving lever 26 is positioned at the middle part of driving lever 26, but is installed with the handle bar 24 of push-and-pull in handle shell 23, and handle bar 24 presses closer the lower end of driving lever 24, the upper end of driving lever 24 is connected with spring 27, spring 27 tension downwards and be connected with the handle shell 23 of lifting handle.As shown in Figure 2, the described elevating mechanism of this electric wheel-chair vehicle also is provided with positioner, and its structure is: the fixing head 31 of positioner is fixed on the chair frame 1, switching locating rod 29 on fixing head 31, and turning cylinder 32 is positioned at the middle part of locating rod 29; The gear teeth of gear 7 are inserted in the upper end of locating rod 29, and strain to the end away from gear by back-moving spring 30 lower end of locating rod 29; The lower end of locating rod 29 connects control the control lock 19 on 3 by brake cable 28.

The another kind of embodiment of this electric wheel-chair vehicle is: described positioner is that chair frame 1 is provided with the lock 36 that rises of checking bull stick, and the lock that rises adopts bicycle expansion brake commonly used, also can use the rotation of control bull sticks 5 such as bicycle band-type brake; The lock 36 that rises connects the control lock by brake cable.The lock 36 that rises is in the tight state of stopping, and holds control during lock when user, and the lock 36 that rises is in releasing orientation, after preventing that suspension rod and suspender belt are raised to certain height, takes place because of the weight of user drives the rotating situation of bull stick.

This electric wheel-chair vehicle is communicated with accumulator and motor in use, and user is controlled walking, stopping of this car by handlebar and brake.User needs at one's leisure, upwards pulls the lifting handle with hands, and lifting handle driven gear, bull stick rotate, and the bull stick of rotation twines halliard, rises thereby drive suspension rod; After the lifting handle is raised to peak, press down the handle bar of lifting handle, the handle bar promotes the bottom of driving lever, makes driving lever leave gear teeth, and at this moment the location-plate of positioner can not turn round gear; After driving lever leaves gear teeth, lifting handle return can be unclamped the handle bar and makes driving lever insert gear teeth under spring action, can repeat lifting.After suspension rod is raised to certain height by suspender belt drive user, can take out out base, carry out convenience.Conveniently finish, behind the base return, user can be by holding the control lock, and gear teeth is left in the upper end that drives locating rod by brake cable, descends the pressure handle bar simultaneously, makes gear lose restriction, thereby revolution sits on the base user again.When positioner is a band-type brake or when rising by lock, realize the rising of suspension rod and suspender belt with the lifting handle, with the degree of tightness of the control lock control band-type brake or the lock that rises, control the lifting of suspension rod and suspender belt.
