Abstract
Disclosed is a stable wheel chair driven by a single motor. The stable wheel chair is composed of a frame, front wheels, a left rear wheel, a right rear wheel, a seat, a motor, a speed and steering control device, a differential mechanism, a first spring buffer mechanism and a second spring buffer mechanism. The differential mechanism comprises a differential mechanism input shaft, a planet wheel, a cone gear, a sun gear, a gear, a framework and a first output shaft and a second output shaft of the differential mechanism. The first spring buffer mechanism comprises a spring, an input shaft, an output shaft and a shaft disc, and the structure of the first spring buffer mechanism is equal to that of the second spring buffer mechanism. By means of the stable wheel chair driven by the single motor, the wheel chair is driven by the single motor, the number of the drive motor is small, the energy consumption is little, and the weight is light; the sudden change of the speed during traveling of the wheel chair is reduced, the wheel chair comfort is improved, and special requirements of special persons (such as the disabled, the old and patients) taking the chair for taking comfort are met.
Description
Technical field:
The present invention relates to a kind of unit and drive steady formula wheelchair, belong to the mechanical field of helping the disabled, help the elderly.
Background technology:
General motor-driven wheelchair has two driving and 4 wheel driven ejector half, when wheelchair turns to, the motors different by the wheelchair both sides drive the both sides wheel with different rotating speeds, thereby forming the different wheel speed in both sides realizes turning to, this type of drive adopts plural drive motors, so that the increase of wheelchair weight, big energy-consuming, cost are high; On the other hand because existing electric wheelchair is to regulate wheelchair speed by the wheelchair governing system, the in the process of moving sudden change of motor output torque can affect the stationarity of wheelchair speed, thereby causes taking advantage of wheelchair-bound special personnel (such as people with disability, old man, patient) to feel uncomfortable.
Summary of the invention:
The present invention relates to a kind of unit and drive steady formula wheelchair, the present invention solves mainly that the drive motors quantity that existing electric wheelchair exists is many, weight large, big energy-consuming, velocity jump is greatly and take uncomfortable problem in motion.The present invention addresses the above problem the technical scheme of taking to be: a kind of unit drives steady formula wheelchair, is comprised of vehicle frame, front-wheel, left rear wheel, off hind wheel, seat, motor, speed and steering control device, box of tricks, the first spring buffer mechanism, the second spring buffer mechanism; Box of tricks comprises box of tricks power shaft, planetary gear, angular wheel, central gear, gear, framework and box of tricks the first output shaft, box of tricks the second output shaft; The first spring buffer mechanism comprises spring, power shaft, output shaft and reel sheet, and the first spring buffer mechanism is identical with the second spring buffer mechanism structure; The output shaft of motor links to each other with the power shaft of box of tricks; The first output shaft of box of tricks links to each other with the power shaft of the first spring buffer mechanism, the second output shaft of box of tricks links to each other with the power shaft of the second spring buffer mechanism, the output shaft of the first spring buffer mechanism is connected with left rear wheel, and the output shaft of the second spring buffer mechanism is connected with off hind wheel.When the output torque of motor was undergone mutation, the linking springs between the input and output shaft of spring buffer mechanism played cushioning effect, and the sudden change of wheelchair speed is reduced, and improved and took the sensation comfortableness.
A kind of unit of the present invention drives steady formula wheelchair and adopts box of tricks to realize single motor-driven wheelchair, drive motors quantity is few, power consumption is little, lightweight, adopt the spring buffer winding machine when wheelchair travels, to reduce the sudden change of speed, improved the wheelchair riding comfort, satisfied and taken advantage of wheelchair-bound special personnel (such as people with disability, old man, patient) to the specific (special) requirements of ride comfort sense, compared tool with background technology and have large improvement.
Description of drawings:
Fig. 1 is structural representation of the present invention
Fig. 2 is the structural representation of box of tricks
Fig. 3 is the structural representation of spring buffer mechanism
The specific embodiment:
The invention will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of unit drives steady formula wheelchair, is comprised of vehicle frame (1), front-wheel (2), left rear wheel (3), off hind wheel (10), seat (4), motor (5), speed and steering control device (6), box of tricks (7), the first spring buffer mechanism (8), the second spring buffer mechanism (9); Box of tricks comprises box of tricks power shaft (17), planetary gear (14), angular wheel (16), central gear (13), gear (18), framework (11) and box of tricks the first output shaft (12), box of tricks the second output shaft (15); The first spring buffer mechanism (8) comprises spring (19), power shaft (22), output shaft (20) and reel sheet (21), and the second spring buffer mechanism (9) is identical with the first spring buffer mechanism (8) structure; The output shaft of motor (5) links to each other with the power shaft (17) of box of tricks; First output shaft (12) of box of tricks links to each other with the power shaft of the first spring buffer mechanism (8), second output shaft (15) of box of tricks links to each other with the power shaft of the second spring buffer mechanism (9), the output shaft of the first spring buffer mechanism (8) is connected with left rear wheel (3), and the output shaft of the second spring buffer mechanism (9) is connected with off hind wheel (10).
When wheelchair turns to, the transmission of power of motor (5) is to box of tricks (7), driving planetary wheel carrier (14) rotates, drive respectively box of tricks the first output shaft (12) by planetary gear (14) again, box of tricks the second output shaft (15), driving box of tricks the first output shaft (12), can allow box of tricks the first output shaft (12) in the time of box of tricks the second output shaft (15), box of tricks the second output shaft (15) is with different rotating speed rotations, make trailing wheel when turning, do not equidistance motion with the pure rolling form as far as possible, avoid the sliding friction on wheel and ground as far as possible.The first spring buffer mechanism (8) is installed between left rear wheel (3) and the box of tricks (7), the second spring buffer mechanism (9) is installed between off hind wheel (10) and the box of tricks (7), the power shaft (22) of the first spring buffer mechanism (8) links to each other by spring (19) with output shaft (20), and the second spring buffer mechanism (9) connected mode is similar to the first spring buffer mechanism (8) connected mode; When the output torque of motor is undergone mutation, the spring that is connected between the first spring buffer mechanism (8) and the second spring buffer mechanism (9) power shaft, the output shaft plays cushioning effect, the sudden change of wheelchair speed is reduced, improve and take the sensation comfortableness, satisfy and take advantage of wheelchair-bound special personnel (such as people with disability, old man, patient) to the specific (special) requirements of ride comfort sense.
