Detailed ways

In order to better understand the utility model, the content of the utility model will be further described below in conjunction with specific embodiments and accompanying drawings, but the utility model is not limited to the following embodiments. See attached drawings 1 to 5:

The novel reclining three-wheeled rickshaw implemented by the utility model mainly includes a human driving mechanism 2, a suspension device 5, a handle 6, a three-wheel mechanism, a backrest type seat 7, a braking device, a speed changer and a vehicle frame 4, etc. Frame 4 front end is connected with manpower driving mechanism 2, and driving wheel 8 is connected at vehicle frame 4 end, and the vehicle frame 4 between manpower driving mechanism 2 and driving wheel 8 is connected suspension device 5, and suspension device 5 is connected with steering wheel 1, The operator lies on the backrest type seat 7 and realizes the movement of the whole vehicle through the manpower driving mechanism 2 . Specifically, it is achieved through the following schemes:

The vehicle frame 4 is made of square steel to reduce the weight of the whole vehicle and ensure the strength. The vehicle frame 4 is a herringbone structure when viewed from the side, and is mainly driven by the main beam at the bottom, the oblique arm 402 protruding obliquely upwards, and connecting manpower. The support beam 3 of the mechanism 2 is connected, and the backrest seat 7 is connected to the main beam at the bottom of the vehicle frame 4 and the inclined arm 402 protruding upward. The backrest seat 7 is a curved shape designed according to ergonomics. And the glass fiber reinforced plastic is molded at one time, the height of the rider's buttocks contact part on the backrest seat is basically the same as the height of the steering wheel 1 wheel center, so the center of gravity of the whole bike plus the rider is much lower than that of a traditional bicycle . Bolts are set inside the backrest type seat 7, and bar-shaped grooves are set on the vehicle frame 4, and the bolts pass through the bar-shaped grooves and are tightened and fixed with nuts. In order to reduce the center of gravity of the whole vehicle, the front and rear ends of the main beam 401 of the vehicle frame are equipped with the 2 parts of the human driving mechanism and the 8 parts of the driving wheel. The end is connected with the driving wheel 8 and the part is bifurcated, and the driving wheel 8 is installed between the vehicle frame 4 bifurcations. The frame main beam 401 and the support beam 3 are plug-in telescopic connections, the support beam 3 is provided with a row of through holes, and the main beam is provided with a through hole, the support beam 3 is inserted into the frame main beam 401, and the connection is fixed with bolts The distance between the seat 7 and the human driving mechanism 2 can be adjusted by selecting different holes on the support beam 3 to satisfy people of different heights.

The manpower drive mechanism 2 of tricycle rickshaw is similar to traditional bicycle drive mechanism, adopts manpower drive mechanism 2 to be the pedal drive mode, and manpower drive mechanism 2 includes sprocket wheel 201, pedal 202, crank linkage, pedal 202, crank The connecting rod mechanism is two sets, symmetrically distributed on both sides of the sprocket 201, the pedal 202 cooperates with the crank, the crank is connected with one end of the connecting rod, the other end of the connecting rod is connected with the rotating shaft, and the rotating shaft passes through the support of the vehicle frame 4 It is connected with the sprocket 201, and the crank linkage mechanism on the other side is connected with the rotating shaft. The sprocket 201 drives the driving wheel 8 installed at the rear of the frame 4 to rotate through the transmission of the chain 203.

Both sides of the main beam 401 of the vehicle frame between the driving wheel 8 and the sprocket 201 are symmetrically connected with a suspension device 5, and the head end of the suspension device 5 is connected with the steering wheel 1, thereby forming two steering wheels in the front and a driving wheel 8 in the back. Three-wheel structure, the diameter of the driving wheel 8 is larger than that of the steering wheel 1, so that the center of gravity is tilted forward, which is convenient for exerting force. When the three wheels touch the ground during driving, everyone can use it with their hands. The suspension device 5 includes an inclined shaft 504, a joint bearing 503, and a connecting beam 501. The middle part of the inclined shaft 504 is connected with the fixed wheel shaft 101 of the steering wheel 1. The upper and lower ends of the inclined shaft 504 are respectively equipped with a joint bearing 503, and the joint bearing 503 is used The nut 502 is connected to the head end of the connecting crossbeam 501, and the other end of the connecting crossbeam 501 is fixedly welded on the main beam 401 of the vehicle frame. Since the height of the main beam 401 of the vehicle frame from the ground is lower than the height of the center of the rotating wheel, the height of the connecting crossbeam 501 Both ends are tilted upwards. The intersection of the extension line of the inclined axis 504 and the ground coincides with the intersection of the steering wheel 1 and the ground, so as to reduce the inclination or camber deviation between the steering wheel 1 and the ground. The inclination angle deviation can be reduced by rotating the upper and lower joint bearings 503 and the nut 502 connecting the beam 501 to adjust the distance between the joint bearing 503 and the connecting beam 501. The nut of the lower joint bearing can reduce the inclination deviation; when the steering wheel 1 is cambered, tighten the nut of the upper joint bearing, and unscrew the nut of the lower joint bearing simultaneously. Because when the tire is tilted or tilted, the friction between the tire and the ground will increase greatly, and the service life of the tire will be shortened, so the ability to adjust the tilt angle is of great significance to the use of the car. Of course, it is also possible to replace the joint bearings with traditional hub bearings, but the cost is higher and the inclination angle cannot be adjusted.

The steering of the tricycle is realized by connecting the turning handle 6 on the fixed wheel shaft 101 between the inclined shaft 504 and the steering wheel 1. The turning handle 6 has a certain length of force arm after being connected with the fixed wheel shaft 101 in an L shape. The inner ring of the joint bearing 503 cooperates, so holding the turning handle 6 to rotate can drive the steering wheel 1 to rotate. During the steering process, the rotation directions and angles of the two steering wheels 1 must be consistent to ensure smooth operation, so the steering linkage lever 601 is hinged between the handlebars 6 on both sides to realize the steering linkage. Using the joint bearing 503 instead of the traditional hub bearing can not only realize the flexible steering of the car, but also facilitate the adjustment of the inclination angle between the wheel and the ground, and also reduce the cost.

Drive wheel 8 and steering wheel 1 are all provided with brake device, and the structure of brake device is identical with existing bicycle brake device structure, is not drawn in the figure, and the mode of brake brake has two kinds: a kind of is to be used for walking and usual Physical exercise, adopt the conventional wiring method that is, two steering wheels 1 are braked by the same brake brake, and the driving wheel 8 is braked by another brake brake. Another way is mainly used for drift stunts, the driving wheel 8 and one side steering wheel are set to combined braking, and the other side steering wheel is independently braked by another brake. The realization of these two brake modes only needs to change the connection of the brake wires.

The speed changer 9 is arranged on the rotating hub of the driving wheel, and the speed regulating device is arranged on the handlebar 6. The same structure as the existing bicycle speed changer, the rotating speed regulating device can replace and select the transmission ratio of the sprocket wheel 201 and the driving wheel 8 .

The above disclosures are only preferred embodiments of the present utility model, and of course the scope of rights of the present utility model cannot be limited with this. Therefore, the equivalent changes made according to the patent scope of the utility model still belong to the scope of the utility model. protected range.
