Abstract
The utility model discloses a recreational human tricycle for the old, weak and sick people to lay fallow, ride instead of walk and keep fit and is characterized in that: a direction mechanism that is arranged on the vehicle frame is connected with a front fork through a flexible connecting piece and the direction mechanism and braking mechanism are provided with a jointly used operating grip; the left and right throw operation grips can realize changing the direction, while a push operating grip can realize applying the brake, so the utility model is quite convenient for operating and suitable for the physiological characteristics of the old, weak and sick people and effectively avoids unfavorable consequences from occurring under the special circumstances that there is no enough time to apply the brake and then result in the accidents. In addition, in order to diminish the volume of the small flywheel, a three stage chain transmission is applied, while the first stage transmission chain and flywheel are hidden in the flywheel bracket, beautiful in whole appearance and safer for using.
Description
Technical field
The utility model relates to a kind of three-wheel vehicle, specifically, relates to a kind of manpower three-wheel leisure vehicle.It is particularly suitable for old, weak, patient lies fallow, ride instead of walk, body-building is used.
Background technology
At present, " bicycle for old people " of commercially available and repacking, just with the volume-diminished of car, weight saving, vehicle seat changes chair form into, and its transmission device, direction mechanism, stop mechanism and ordinary bicycle, three-wheel vehicle are identical.The major defect of this structure is: the operating handle of direction mechanism and stop mechanism separates, and is not suitable for body reason characteristics old, weak, patient, in particular cases has little time braking and causes the accident.
Summary of the invention
The purpose of this utility model is exactly in order to overcome the shortcoming of above-mentioned existing " bicycle for old people ", to avoid taking place above-mentioned negative consequence, a kind of manpower three-wheel leisure vehicle being provided.
The technical solution of the utility model is: a kind of manpower three-wheel leisure vehicle, comprise forward and backward wheel, vehicle frame, vehicle seat, transmission device, direction mechanism, stop mechanism, it is characterized in that: described direction mechanism is located on the vehicle frame, and is connected with front fork by flexible connecting member; Direction mechanism and stop mechanism are established a shared operating handle.
Described transmission device is three grades of chain drives; The first order, the second stage are the geometric ratio transmission, and the third stage is the no-load voltage ratio transmission, and driving wheel is a flywheel; Flywheel and first order messenger chain is hidden is located in the flywheel-bracket.
Described vehicle seat is a single seat, establishes a sets of transmission mechanism.
Described vehicle seat is a two-seater, establishes the separate transmission device that is symmetrically arranged of two covers.
Described vehicle seat is adjustable being connected in front and back with vehicle frame, and its handrail is foldable flexible connection.
Described flexible connecting member is a steel cable, and this steel cable is hidden to be arranged in the vehicle frame pipe.
Advantage of the present utility model: mainly be the shared same operating handle of direction mechanism, stop mechanism, the left and right operating handle of pulling can be realized turning to, press down operating handle and can realize braking, operation is very easy, avoided in particular cases having little time to brake the negative consequence that causes the accident effectively; In addition, adopt three grades of chain-drivings for dwindling the flywheel volume, the driving chain of the first order and flywheel are hidden in flywheel-bracket, and not only monnolithic case is attractive in appearance, and uses safer; Also have, rational in infrastructure on the whole, and practical.Just owing to have described characteristics, this three-wheel RV recreational vehicle is given people's sense safe in utilization, not only easily enters family, and enters recreation ground very big market is also arranged.

The specific embodiment
Describe the utility model in detail below in conjunction with accompanying drawing.
Referring to Fig. 1---Fig. 6: this manpower three-wheel leisure vehicle comprises forward and backward wheel 11, vehicle frame 14, vehicle seat 3 and transmission device, direction mechanism, stop mechanism.Direction mechanism is made up of steering wheel 15, direction lever 6, direction lever sleeve pipe 7 and the operating handle 4 of front fork steering wheel 10, steel cable 20, steel cable track adjusting wheel 21, band boomer 26.Its direction lever sleeve pipe 7 vertically is fixed on the vehicle frame 14, direction lever 6 is located in the direction lever sleeve pipe 7 and movable with it the cooperation, direction lever 6 upper end attended operation handles 4, the affixed steering wheel 15 in lower end, steel cable 20 is around front fork steering wheel 10 and steering wheel 15, and affixed by screw 27 and front fork steering wheel 10, boomer 26 respectively.Like this, the left and right operating handle 4 of pulling makes direction lever 6, steering wheel 15 deflections, through steel cable 20 transmissions, can drive the 10 synchronous deflections of front fork steering wheel, realizes turning to.Elongatedly turn to ineffectively for preventing that steel cable 20 usefulness from stretching for a long time, the bolt 25 that can adjust on the boomer 26 tightens up steel cable 20, and steel cable 20 is hidden to be located in the vehicle frame pipe 19 and by track adjusting wheel 21 guiding.Stop mechanism is made up of drg 12, steel cable 5, steel cable track adjusting wheel 21 and operating handle 4, drg 12 is located on rear wheel 11 outer shaft, passing direction lever 6 by steel cable 5 links to each other with the lever 24 of operating handle 4, steel cable 5 is by guides 18 guiding that are fixed on the vehicle frame 14, and operating handle 4 is movably connected by the axle 22 on kink 23 and the direction lever 6.Like this, need only press down operating handle 4, lever 24 can tighten up steel cable 5 to top offset, realizes braking.Transmission device is three grades of chain drive structures, is made up of flywheel 9, breast wheel 17,31,29,30 and flower wheel 13, the chain 16 of band foot-operated 8, and driving wheel is a flywheel 9; Flywheel 9 and first order driving chain 16 hidden being located in the flywheel-bracket 28 are adopted this hidden setting, both are suitable for, and are safe again, attractive in appearance; Flower wheel 13 is located on rear wheel 11 inner shafts, and breast wheel 17,31,29,30 is connected with vehicle frame 14 by axle, bearing; The geometric ratio transmission is adopted in the first order, the second stage, and the third stage is adopted the no-load voltage ratio transmission, and for adapting to old leisure characteristics, transmitting ratio should not be too big, in order to avoid require great effort very much, and the high unfavorable safety of the speed of a motor vehicle.Vehicle seat 3 is provided with slideway with vehicle frame 14 junctions, and vehicle seat 3 front and back are adjustable, is convenient to the different people of height and uses; Handrail 2 flexibly connects the folding that can make progress, convenient for passenger to get on and off by kink and vehicle frame 14; Behind the seat of vehicle seat 3, be provided with and lean against 1, also be provided with at the bottom of vehicle seat 3 and rear portion and put object location.This manpower three-wheel leisure vehicle can be single seat (as shown in Figure 6), establishes a sets of transmission mechanism, and flywheel 9 is located on vehicle frame 14 axis, and flower wheel 13 is located at arbitrary rear wheel 11 inboards.
But this manpower three-wheel leisure vehicle is two-seater side by side also, and except that the separate transmission device that is symmetrically arranged of establishing the above-mentioned structure of two covers (as shown in Figure 7), other structure is same as described above.
