Description

Mother and baby's multipurpose three-wheel car

The utility model relates to a kind of multipurpose three-wheel car.

Bicycle is the most popular vehicle of China resident at present, because it can be applicable to different kinds of roads, expense is low, bring a lot of convenience to the user, but because the operation easier of existing two-wheel car, three-wheel vehicle is big, all have defectives such as driving safety difference, especially the mother and baby brings a lot of troubles for people's life with taking advantage of the accident rate height.

In view of the deficiency of above-mentioned prior art, the purpose of this utility model is to increase by one to help balancing device on the basis of existing three-wheel vehicle, provides a kind of meeting not drive mother and baby's multipurpose three-wheel car that two-wheel car, three-wheel vehicle person all can use and be highly suitable for mother and baby and band thing.

For achieving the above object, technical solution of the present utility model is: a kind of mother and baby's multipurpose three-wheel car, and it comprises handlebar, car front fork, wheel, transmission device, vehicle frame, vehicle bridge, compartment and compartment supporting seat, it is characterized in that: vehicle bridge is approximately

Type, the crossbeam above it are V-type; The place of connecting to ground helps balancing device in vehicle bridge, help balancing device to comprise balance shaft, bearing, bearing seat, balance handle and extension spring, there is fixed hole seat the front-end bearing pedestal top, front-end bearing pedestal is fixed on the vehicle bridge front end, rear bearing block is fixed on the bottom of the V-type crossbeam on the vehicle bridge, balance shaft links together by bearing and forward and backward bearing seat, and balance handle is vertically fixed on the balance shaft, and is connected together by the extension spring at left and right two ends and the left and right bridging of vehicle bridge; Vehicle frame is connected on the balance shaft by stay bearing plate by having putting on the shelf of locknut, the vehicle frame undercarriage is fixed on below the balance shaft, the locking bar that bonded assembly supporting with it is with spring is housed on the locknut, front compartment supporting seat and vehicle bridge fwd two fulcrums link together, the trunk supporting seat is connected with the vehicle bridge rear end by shock absorber, and the compartment is fixed on the supporting seat of front and back.

The described compartment of the utility model multipurpose three-wheel car is made up of camber line shape railway carriage or compartment bucket and the overlapping railway carriage or compartment lid supporting with it, flexibly connects between railway carriage or compartment lid and the railway carriage or compartment bucket, and railway carriage or compartment bucket front end has ventilation inlet, and its rear end has air outlet.

Because the utility model is equipped with at the vehicle bridge place of connecting to ground and helps balancing device, when locknut, locking bar are not connected with the bearing seat of vehicle bridge front end, car travels when concavo-convex road surface, perhaps during the left and right inclination of rider oneself, handlebar left and right swing can not occur, therefore can the tricyclist can not drive yet; After locknut, locking bar and front-end bearing pedestal are locked, can make common three-wheel vehicle and use, so usability is strong.Because compartment of the present utility model adopts the movable railway carriage or compartment of eclipsed form lid, protecgulum and bonnet have the sunshade effect when overlapping, when protecgulum and bonnet are end to end, be round-the-clock effect, when forward and backward lid all falls back on bucket rear end, railway carriage or compartment, also can be used as the usefulness of loading, so easy to use.

Below in conjunction with accompanying drawing and specific embodiment in detail the utility model is described in detail.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is vehicle bridge among Fig. 1, balancing device, vehicle frame spatial structure decomposing schematic representation;

Fig. 3 is the railway carriage or compartment bucket spatial structure decomposing schematic representation of the overlapping railway carriage or compartment of Fig. 1 band lid.

As Fig. 1, shown in Figure 2, the utility model comprises wheel, handlebar, the car front fork, transmission device, vehicle frame, vehicle bridge, help balancing device, compartment and compartment supporting seat, before the compartment is reached by camber line shape railway carriage or compartment bucket 24, back railway carriage or compartment lid 22,23 form, before, be movably connected by locknut 25 between back railway carriage or compartment lid and the railway carriage or compartment bucket, railway carriage or compartment 24 front ends that struggle against have two ventilation inlets 26, the rear end has two air outlets 27, before the compartment is fixed on, trunk supporting seat 6, on 1, back supporting seat 1 is fixed on vehicle bridge 2 rear ends by shock absorber 20, front compartment supporting seat 6 is fixed on vehicle bridge 2 fronts by two fulcrums 16, and vehicle bridge 2 is approximately Type, crossbeam 19 is the V-type crossbeam, front-end bearing pedestal 13 is fixed on the vehicle bridge front end, the front-end bearing pedestal top is welded with fixed hole seat 10, rear bearing block 21 is fixed on V-type crossbeam 19 bottoms, before, rear bearing block is on same horizon, balance shaft 3 passes through the bearing fixing at two ends preceding, on the rear bearing block, balance handle 5 is vertically fixed on the balance shaft 3, a vehicle bridge left side, be welded with permanent seat 17 on the right bridge, a left side on the balance handle 5, right two ends are welded with permanent seat 4, four permanent seats are on same horizontal surface, extension spring 18 is fixed on four permanent seats, vehicle frame 11 tail ends of putting on the shelf are welded with locknut 9, and be connected by dowel fixes with an end of stay bearing plate 14, the other end of stay bearing plate 14 passes through dowel fixes together with the permanent seat 15 that is welded on the balance shaft 3, vehicle frame undercarriage 12 is welded on balance shaft 3 bottoms, supporting seat 6 links together with two fulcrums 16 of vehicle bridge 2 front ends welding before the compartment, back supporting seat 1 links together by shock absorber 20 and vehicle bridge 2 rear ends, the locking bar 7 that is with spring 8 is contained in the locknut 9, when locking bar 7 is tightened with the fixed hole seat 10 of front-end bearing pedestal 13 tops, help balancing device not work, can be used as common three-wheel vehicle and use; When locking bar 7 breaks away from the fixed hole seat 10 of front-end bearing pedestal top, help balancing device to devote oneself to work, when the handlebar right steering, balance handle on the balance shaft and vehicle frame are garden mind-set right bank with the balance shaft, and chaufeur is tilted to the right, and the force of inertia of generation acts on the balance handle along vehicle frame, the moment loading that balance handle produces is on Zola's spring, the pulling force that Zola's spring produces has overcome this moment, makes balance handle, vehicle frame perpendicular to balance shaft, thereby the auxiliary handlebar involution is kept straight on; When the handlebar left steering, the moment loading that produces is in right extension spring, the pulling force that right extension spring produces has overcome this moment, thereby the auxiliary handlebar involution is kept straight on, car is kept straight on when concavo-convex road surface, when back axle right bank during in ground, bridge extension spring permanent seat in a vehicle bridge left side stretches Zola's spring, the pulling force that Zola's spring produces has overcome this application force, and balance handle keeps vertical axletree constant, thereby auxiliary vehicle frame is perpendicular to ground level, when back axle left bank during in ground, extension spring permanent seat on the right bridge of vehicle bridge stretches extension spring, and the pulling force that right extension spring produces overcomes this application force, thereby auxiliary vehicle frame is perpendicular to ground level.
