Description

Light tricycle

Light tricycle is the motor moped that a kind of energy is manned or freight, and belongs to small vehicles.

For a long time, people are accustomed to using two-wheeled cycle, run into need manned---as when picking the preschool child, little seat have to be set on the car beam, when needing the band article, then can only hang on the handle and be bundled on the rear object carrier, both inconvenient, dangerous again, it is more difficult especially to meet wet weather, severe cold weather.

The purpose of this utility model is to address the above problem, and provides a kind of can the use as ordinary bicycle again can the manned or multifunctional portable tricycle of dress shipping parcels.

Light tricycle adopts woman style camber beam bicycle predecessor, connect with turning to leaning device and transmission device by the back rest, back vehicle frame is fixed on the turning sleeve and axle sleeve that turns to leaning device and transmission device, the two side channels below of back vehicle frame is installed with two trailing wheels, and dual-purpose basket has been installed in the top of back vehicle frame; The trailing wheel of car is less than front-wheel, between two trailing wheels apart from and front body two handles between distance quite.

Be described in detail the utility model below in conjunction with accompanying drawing

The light tricycle block diagram of Fig. 1;

Fig. 2 turns to the leaning device block diagram;

Fig. 3 transmission device scheme drawing;

The dual-purpose basket of Fig. 4 block diagram;

Vehicle frame birds-eye view behind Fig. 5.

Light tricycle shown in Figure 1 mainly by woman style camber beam front body (1), the back rest (2), turn to leaning device and transmission device (3), trailing wheel (4), back vehicle frame (5) and dual-purpose basket (6) to form.Front body (1) comprises front vehicle frame, handle, front-wheel, vehicle seat, pedal transmission mechanism etc., front body (1) is by the back rest (2) and turn to leaning device and transmission device (3) to link, back vehicle frame (5) is fixed on the turning sleeve (7) and the axle sleeve (11) that turn to leaning device and transmission device (3) and goes up (referring to Fig. 3 and Fig. 5), back vehicle frame (5) down either side is installed with two trailing wheels (4), dual-purpose basket (6) is installed above the back vehicle frame (5), and dual-purpose basket (6) is in transition intermediateness manned or loading.

The leaning device that turns to shown in Figure 2 is mainly by the back rest (2), turning sleeve (7), locating dowel pin (8), spring (9), axle sleeve formations such as (11).The back rest (2) and the loosening socket of the turning sleeve (7) that turns to inclination and transmission device (3), all have the strip shape pin-and-hole on the back rest (2) and the turning sleeve (7), aforementioned socket is to pass the pin-and-hole location by locating dowel pin (8), retracing spring (9) has been installed at locating dowel pin (8) two ends, the other end of spring (9) is separately fixed on turning sleeve (7) and the axle sleeve (11), and turning sleeve (7) and axle sleeve (11) vertical fixing are one; During turning of bicycle, the back rest (2) can be in turning sleeve (7) left or Right deviation change, maximum tilt angle is 30 degree, so trailing wheel (4) can not break away from ground, also can not produce and take off the chain situation, when not turning, retracing spring (9) can make vehicle body be in erectility.

Shown in Figure 3, transmission device is mainly by axle (12), bearing (14), axle sleeve (11), inner casing (15), sprocket wheel (10), outer casing (16), bolt formations such as (17).A bearing (14) is respectively being adorned at axle (12) two ends, be enclosed within then in the axle sleeve (11), on the axle head outside the bearing (14) trailing wheel (4) has been installed, on the axle head outside another bearing (14) inner casing (15), sprocket wheel (10), outer casing (16) are installed successively, use bolt (17) that they are fixed tightly on the axle (12) then; Unclamp bolt (17), take off outer casing (16), just the chain on the sprocket wheel (10) can be loaded onto or pulled down; The axle head of trailing wheel (4) is installed, and its profile is a square, and inner chamber has screw thread, rotates the four directions and just can load onto or pull down trailing wheel (4).

Dual-purpose basket shown in Figure 4 (6) mainly is made of basket (18), backrest (also claiming the basket lid) (19), hinge joint cross bar (21) and seat (22).The rear side both sides of basket (18) has the guided bearing groove (20) of symmetry, backrest (19) links to each other by the hinge joint cross bar (21) that two ends are arranged in guided bearing groove (20) with seat (22), and hinge joint cross bar (21) and guided bearing groove (20) lead and position-limiting action to moving up and down and having rotated of backrest (19) and seat (22).Seat (22) can rely on backrest (19) by hinge joint cross bar (21) rotation, when backrest (19) is thus lifted to hinge joint cross bar (21) and is arranged in the extreme higher position of guided bearing groove (20), it is rotated to level attitude again and just forms basket lid (19).

Backrest shown in Figure 4 (19) is that hinge joint cross bar (21) is in the extreme lower position in the guided bearing groove (20), and backrest (19) is upright, promptly sits child's position; The position of dual-purpose basket shown in Figure 1 (6) is the transition midway location, promptly basket lid (19) has risen to the extreme higher position, as long as seat (22) is folded to the basket lid, the thing of just can freighting, right institute rotates to level attitude with basket lid (19), just basket (18) has been covered, can also they have been locked with lock.
