Abstract

A detachable wheelchair tricycle has total functions of a wheelchair, a bicycle and a three-wheeled vehicle. The wheelchair tricycle comprises a bicycle, a wheelchair, a camber beam and a steering gear, the bicycle is provided with a shaft sleeve, the camber beam is hinged with a shaft pipe of the wheelchair, the other end of the camber beam is provided with a mandrel and a back nut, the steering gear is arranged at a bending position of the camber beam, a lateral supporting rod of the steering gear is connected with the shaft pipe of the wheelchair through a connecting rod, and a front supporting rod of the steering gear is connected with a front fork of the bicycle to form a four-rod linkage mechanism. When assembling the tricycle, a front wheel of the bicycle is detached firstly, the mandrel on the camber beam is inserted in the shaft sleeve of a bicycle beam, the front fork of the bicycle is connected onto the front supporting rod of the steering gear, and then the back nut is locked, thereby assembling the tricycle. When a bicycle handlebar rotates, the front fork leads the steering gear to wiggle through the front supporting rod and drives the shaft pipe of the wheelchair to rotate through the lateral supporting rod and the connecting rod, thereby achieving the purpose of steering the tricycle. In addition, the wheelchair tricycle can be divided into a wheelchair and a bicycle respectively.

Description

The wheelchair tricycle

Affiliated technical field

The utility model relates to a kind of wheelchair tricycle, especially a kind of wheelchair tricycle detachable, that have wheelchair, three-wheel vehicle and bicycle repertoire.

Background technology

At present, general wheelchair needs manpower to promote to travel, and trammer's muscle power can consume very big, and trip is limited in scope, and degree of utilization is very low; Though three-wheel vehicle can be with people's fast running, it is also bigger to go out line range, and public places such as park, hospital, market can't enter; And bicycle band people to travel be comparison danger, more uncomfortable crossed belt old man trip.

Summary of the invention

For overcoming the existing intrinsic problem of existing wheelchair, three-wheel vehicle and bicycle, the utility model provides a kind of wheelchair tricycle, the structure of wheelchair and bicycle is transformed, make it and to connect together, being a three-wheel vehicle during connection, is respectively again a wheelchair and a bicycle in the time of separately.

The technical scheme that its technical matters that solves the utility model wheelchair tricycle adopts is: adopt fixedly vehicle frame formula wheelchair of a rough turn beam type bicycle and, an axle sleeve is installed on the car beam of bicycle; Have a camber beam hinged with it on the central siphon of wheelchair, the other end of camber beam is installed by mandrel and the back of the body is female; Bending part at camber beam is installed a deflector, and two side poles of deflector are connected with the central siphon of wheelchair by two connecting rods, forms four-bar linkage, and the front support rod of deflector can be connected with bicycle front fork; Assembling is taken the front-wheel of bicycle earlier during three-wheel vehicle, and the mandrel on the camber beam is inserted in the axle sleeve on the bicycle beam, and bicycle front fork is connected on the deflector front support rod, and the locking back of the body is female then, promptly becomes a three-wheel vehicle; When the handlebar of bicycle rotated, front fork twisted deflector by front support rod, and by side pole and connecting rod, drove the wheelchair central siphon and rotate, to reach the purpose that three-wheel vehicle turns to.

The beneficial effects of the utility model are a car three usefulness, save muscle power when riding, and have improved the degree of utilization of wheelchair simultaneously, can use as bicycle and wheelchair respectively again in the time of separately.

Among the figure:

1. bicycle, 2. wheelchair, 3. camber beam, 4. deflector, 5. axle sleeve, 6. front fork, 7. mandrel, 8. the back of the body is female, 9. front support rod, 10. connecting rod, 11. side poles, 12. hinges, 13. central siphons.

The specific embodiment

Figure 1 shows that agent structure, comprise bicycle (1), wheelchair (2), camber beam (3) and deflector (4) as three-wheel vehicle.

Fig. 2 is the structure of bicycle, and axle sleeve (5) and front fork (6) are installed on the bicycle (1).

Fig. 3 is the structure of wheelchair, and camber beam (3) is installed on the wheelchair (2), and the deflector of being made up of front support rod (9), side pole (11) (4) is installed on the camber beam (3), and camber beam (3) also is equipped with the mandrel (7) and the back of the body female (8).

Fig. 4 is the structure on wheelchair chassis, and the hinge (12) that wheelchair (2) and camber beam (3) are linked together is installed on the central siphon (13), between the side pole (11) of deflector (4) and the central siphon (13) of wheelchair (2) connecting rod (10) is installed.

During the combination three-wheel vehicle, mandrel (7) is inserted into axle sleeve (5) lining, screws the back of the body female (8) then, bicycle (1) is connected with camber beam (3); Camber beam (3) is hinged by the hinge (12) on the central siphon (13) with wheelchair (2); The front fork (6) of bicycle (1) is installed on the front support rod (9), and front fork (6) is connected with deflector (4); Connecting rod (10) is installed between side pole (11) and the central siphon (13), and deflector (4) is connected with central siphon (13); Thus, bicycle (1) links together by axle sleeve (5), mandrel (7), the back of the body female (8), camber beam (3), front fork (6), deflector (4) with wheelchair (2).

Claims

1. wheelchair tricycle, comprise bicycle (1), wheelchair (2), camber beam (3) and deflector (4), axle sleeve (5) and front fork (6) are installed on the bicycle (1), camber beam (3) is installed on the wheelchair (2), mandrel (7), the back of the body female (8) and deflector (4) are installed on the camber beam (3), it is characterized in that: bicycle (1) links together by axle sleeve (5), mandrel (7), the back of the body female (8), camber beam (3), front fork (6), deflector (4) with wheelchair (2).
