Description

The wagon box of passenger-cargo dual-purpose tricycle

Technical field

The utility model relates to a kind of rickshaw, battery-driven car or self-propelled vehicle three-wheel vehicle wagon box, especially relates to a kind of wagon box of passenger-cargo dual-purpose tricycle.

Background technology

Usually the wagon box of manual tricycle or three wheeled motor car can only loading or can only carrying, and its function singleness is used inconvenience.Though disclosed mixed-traffic wagon box is also arranged, as CN2436399Y disclosed " a kind of three-wheel vehicle ", be to be movably hinged with collapsible seat in both sides, wagon box upper end, when three-wheel vehicle needs loading, conter clockwise rotates folding seat, the backrest of seat is withstood on the wagon box bottom surface, the anterior baffle plate of seat as wagon box sealed wagon box, promptly can be becomes loading space.When rotating folding seat in the clockwise direction, its backrest bottom frame is leaned against the upper end of wagon box, make the seat cushion level, can be manned.Though this three-wheel vehicle has mixed-traffic function, this seat is the top that is hinged on wagon box, when manned, because the increase of the height of gravitational center of wagon box, and driving safety is descended.On the other hand, because seat only as the front apron in compartment, has increased the car load deadweight, the heaviness of travelling.

Summary of the invention

The purpose of this utility model provides a kind of simple and reasonable for structure, and it is light to travel, safe and reliable can be manned again can the cargo-carrying passenger-cargo dual-purpose tricycle wagon box.

The further purpose of the utility model provides a kind of wagon box bottom and has wagon box than the passenger-cargo dual-purpose tricycle of large space.

The purpose of this utility model is achieved in that a kind of wagon box of passenger-cargo dual-purpose tricycle, comprise by two side shields and front cross rail, the wagon box frame that after cross member constitutes, and front apron and back shield, it is characterized in that: also comprise the interlock plate and with interlock front edge of board pivotally attached gangbar, side shield also is fixed with strutbeam, the other end of gangbar is hinged on the strutbeam, and the rear portion of interlock plate is hinged with the back backup plate, make gangbar, interlock plate and back backup plate constitute connecting rod mechanism, the limit shaft that is connected in backup plate bottom, back moves in the guide groove of wagon box frame bottom, the top of back backup plate is hinged with front apron, and front apron has respectively and side shield and back backup plate corresponding locking mechanism when being connected.

The utility model for the technical scheme that realizes above-mentioned further purpose is: the both sides of wherein said wagon box frame bottom also are connected with wheel carrier, and axle bed and trailing wheel axle bed before being fixed with on the wheel carrier of a side, the intermediate chain wheel before being contained on the axle bed links to each other with back sprocket wheel on the trailing wheel axle bed by rear chain.

Compared with prior art, good effect of the present utility model is: owing to adopt gangbar, interlock plate and back backup plate as connecting rod mechanism, by the mutual motion between interlock plate and the gangbar, can make the back backup plate keep flat or open, make wagon box have loading or manned double-purpose functional.Because of the back backup plate both as the wagon box base plate in when loading, make the backrest when being manned again, and the interlock plate is both as the rod member of interlock, again as seat support, so wagon box is rational in infrastructure, simple, from heavy and light, it is light to travel.On the other hand because lower as the interlock Board position of seat support, can reduce the height of gravitational center of wagon box when manned, improve the reliability of vehicle '.Moreover, because the wheel carrier one side of bottom of frame has preceding axle bed and trailing wheel axle bed, and the secondary transmission device that the intermediate chain wheel on preceding axle bed and the trailing wheel axle bed, back sprocket wheel and rear chain constitute, increased the space of wagon box bottom on the one hand, especially for electro-tricycle, high-capacity battery can be arranged in its wagon box bottom, three-wheel vehicle is by the secondary transmission on the other hand, can conveniently change transmitting ratio, reach rational transmitting ratio, but also can play the power-assisted effect of manpower.
