Abstract

The utility model relates to a tricycle, the rear wheels of which are capable of folding from vertical to horizontal positions. In the tricycle, both sides of the rear part of the frame are respectively provided with a collapsible parallelogram linkage; a driving shaft and a driven shaft are arranged under the left parallelogram linkage; the driving shaft and the driven shaft are hinged to a coupling rod via shaft pins; the driven shaft is made into a folding shaft; a stationary shaft is arranged under the right parallelogram linkage; the driven shaft and the end of the stationary shaft are provided with rear wheels. The rear wheels of the tricycle can be vertically and horizontally folded, and the utility model requires three fifths of the occupation area of the adult bicycles. The utility model has the advantages of small volume, light weight and convenient commodity circulation and storage. The tricycle which can not only be placed indoors, but also be carried on buses is suitable for the modification of all kinds of tricycles.

Description

Folding tricycle with rear wheels capable of transversely and longitudinally folding

This novel improvement that relates to a kind of three-wheel vehicle.

Existing three-wheel vehicle mostly is fixed sturcture, and car load can not fold, and it is bigger to take up room, and deposits and carry all very inconvenient.

This novel purpose provide a kind of take up room little collapsible and deposit and folding tricycle with rear wheels capable of transversely and longitudinally folding easy to carry.

This three-wheel vehicle mainly comprises vehicle frame, handlebar, vehicle seat, wheel, driver train and stop mechanism are formed, it is characterized in that the vehicle frame rear portion and on open and have four folder fin axis hole its rear end to have upwards the saddle of the positioning plate of bending is rigidly connected, saddle is hinged with folding rod one end respectively by folder fin and pin shaft hole, the folding rod other end is hinged and constitute two groups of parallelogram lindages in the vehicle frame bilateral symmetry with the movable stand end respectively, the folding rod registration device is installed on the saddle simultaneously, saddle and vehicle frame below are fixed with the dead axle that imput shaft is housed in it and support, being fixed with the mobile shaft that driven axle is housed in it below the movable stand of left side supports, hinged with coupling lever one end respectively between imput shaft and the driven axle by the axostylus axostyle pin, the terminal revolver of installing of driven axle, the imput shaft other end is connected with stop mechanism with chain drive mechanism respectively with brake wheel by flywheel, and the right side movable stand had the mobile support that anchor shaft is housed in it in following minute surely, the terminal right side wheel of installing of dead axle.

Embodiment 1

Shown in Fig. 1-4, this three-wheel vehicle mainly comprises vehicle frame, handlebar, vehicle seat, wheel, driver train and stop mechanism are formed, vehicle frame 19 rear portions and saddle 1 are rigidly connected, its rear end has the upwards positioning plate 27 of bending, and have four folder fin axis holes on the saddle, saddle is hinged with folding rod 2 one ends respectively by folder fin 11 and pin shaft hole, the folding rod other end is hinged and constitute two groups of parallelogram lindages in the vehicle frame bilateral symmetry with movable stand 4 ends respectively, the folding rod registration device is installed on the saddle simultaneously, comprise two inverted U-shaped locating racks 10 that have chucking lug 24 on it respectively, the inboard end of locating rack is hinged with saddle respectively, below saddle and vehicle frame, be fixed with the dead axle that imput shaft 9 is housed in it and support 3, movable stand below, left side is fixed with the mobile shaft that driven axle 6 is housed in it and supports 5, hinged with an end of coupling lever 7 respectively between imput shaft and the driven axle by axostylus axostyle pin 8, and two axostylus axostyle pins are positioned at same plane, the terminal revolver 20 of installing of driven axle, the imput shaft other end is by flywheel 17, chain 18, wheel disc 15 is connected with chain drive mechanism, be connected with stop mechanism by brake wheel on the imput shaft 16 and brake collar 12 simultaneously, movable stand below, right side is fixed with the mobile dead axle that dead axle 14 is housed in it and supports 13, the terminal right side wheel 23 of installing of dead axle, be positioned at the saddle top on the vehicle frame and a Basket on bicycle for containing article 21 be installed by hinge 22, when folding the Basket on bicycle for containing article upset is placed on the vehicle seat, simultaneously with the upwards interior upset of locating rack 10, to put down locating rack after wheel and the inwardly folding gathering of movable stand then, rugosity such as Fig. 1, reverse operating opens car exhibition as Fig. 2 during use.

This case folding rod registration device also can adopt an inverted U-shaped locating rack, and the locating rack middle part is hinged by connecting rod and saddle, and contacts with saddle upper limit plate, prevents that locating rack from falling, as Fig. 6.

This registration device also can be realized the location by the knock hole on spring pin of installing on the folding rod and the positioning plate, as shown in Figure 5.

Embodiment 2.

As shown in Figure 7, by hinge 22 adult's chair 25 is installed and makes the two people car of riding instead of walk of travelling on vehicle frame, all the other structures are with example 1.

Embodiment 3.

By hinge 22 baby' chair 26 is installed as shown in Figure 8 on vehicle frame, is made mother and sons' car form, all the other structures and example 1 are together.

Embodiment 4.

As shown in Figure 9, this example adopts the f-w-d brake equipment of installing on the front wheel spindle, this device can be selected the driving brake equipment (or actuating device of other form) that proposes in the 93242404X patent of the previous application of the applicant and No. 95224566.3 patents for use, concrete structure as shown in figure 10, all the other structures are with example 1.

This tricycle advantage and effect: 1. this back wheels of vehicle can fold in length and breadth, and volume is little, takes up an area The Area Ratio adult bicycle is little by 2/5, is convenient to circulation of commodities and deposits; 2. this design is suitable for institute The light manpower tricycle is arranged, and level of all ages all can use, especially towards aging society More suitable; 3. this car has solved in the past most of light manpower tricycle and has deposited in outdoor wind Change, Exposure to Sunlight, drench with rain or stolen or the hard nut to cracks such as the people destroys are arranged, can deposit after this car is folding Be put in indoorly, it is little to take up room, in light weight, can carry by bus simultaneously, easy to use; 4. this car can be designed to the seat formula such as two people play scooter or parent-subsidiary vehicle etc., as with manpower three Wheel car goods bucket, the goods bat is designed to collapsible, and this scheme also is applicable to all manpower tricycles simultaneously Car.
