Description

A kind of multifunctional folding handcart
Technical field
The present invention relates to a kind of foldable luggage trolley that has car and two kinds of functions of baggage container simultaneously.
Background technology
The luggage lodge is that people go on business, go to work and carry the common tool of laptop computer, office appliance and other luggage and articles.When luggage more after a little while, can select light portable or shoulder back of the body baggages for use; But when luggage more for a long time, then to use the big briefcase of matter-loading amount, in its bottom wheel is installed, the user when walking with hand push, draw and drive.Obviously, if luggage is too heavy, merely with hand push, to draw be more laboriously, particularly far away for the walking distance, the time, it was very inconvenient to walk in the time of nervous again.
Bicycle is the long-term widely used a kind of vehicle of people.For the ease of carrying and keeping, various Folding Bicycles arise at the historic moment.The bicycle designs function singleness fails to play one's part to the full but for a long time.
The patent No. is that the Chinese utility model patent of ZL200420019801.4 discloses a kind of " electric trunk ", is made up of casing, wheel, vehicle wheel frame, supporting leg, storage battery, Transmission and movable handle; Bottom half is equipped with foldable vehicle wheel frame and supporting leg, under the vehicle wheel frame wheel is installed, and the bottom of casing is provided with storage battery, and storage battery provides kinetic energy to Transmission, the Transmission drive wheels; Bumper and brake gear are housed above the wheel; The bottom of casing also is provided with micro-motor and charger.During use, it provides the electric energy drive wheels to drive casing by storage battery, can save manpower, makes things convenient for the tourist, but it is a simple baggage container still, can't play manned effect as walking-replacing tool.
The patent No. is that the Chinese utility model patent of ZL200420091867.4 discloses a kind of " portable electric baggage car ", adopt square car body, at the front portion of car body installing guide front wheel, front-wheel handlebar by the load of scalable convertible handlebar connecting leg, the handlebar connecting leg is connecting transverse axis pipe running-fit and is connecting the connecting shaft sleeve pipe of Vehicular body front and connect the location by dowel bolt, on the rear body of vehicle frame, be fitted with two back wheels of vehicle side by side, one sidecar trailing wheel is that power wheel is equipped with sprocket wheel and connects electrical motor by chain, electrical motor is connecting storage battery, and on trailing wheel, be fitted with brake actuator, also on car body, be fitted with the platform-type vehicle seat that the energy folding supports, be fitted with the folding type bicycle basket that basket was deposited and be opened into to the energy folding before the car body in the case.As buggy, its load-carrying capacity is strong, and the roping article are light laborsaving, can be according to using the needs conversion to amount to.But its essence is a simple car, user's luggage and articles also need to package with baggage container in addition to put onboard, during individual out using, carry and inconvenient.And its complex structure, member is many, and volume is big.
Summary of the invention
Of the present invention providing a kind ofly promptly can be used as baggage container, can be used as the multifunctional folding handcart of the vehicle again.
For reaching above-mentioned purpose, multifunctional folding handcart structure of the present invention is as follows: comprise baggage container, the outside of baggage container is fixed with forward and backward steering shaft respectively, forward and backward steering shaft is connected with forward and backward pull bar by forward and backward eccentric pivoted arm respectively, is equipped with steering lock spare between forward and backward pull bar and the forward and backward eccentric pivoted arm and between forward and backward eccentric pivoted arm and the forward and backward steering shaft; Forward and backward pull bar lower end is separately installed with front and rear wheel; The front tension bar upper end is provided with handlebar, and the back stay upper end is provided with seat cushion; Front-wheel or trailing wheel are connected with wheel driver.The user is put in luggage and articles in the baggage container, and is current, when forward and backward steering shaft forwarded the most preceding and rearmost end of baggage container to and locks, baggage car of the present invention can be used as car and rides back stay respectively; Current, back stay respectively when forward and backward steering shaft forwards baggage container one side to and locks, baggage car of the present invention promptly as an available hand push, draw the baggage container that advances.
As a kind of improvement, described arbitrary steering shaft and connected eccentric pivoted arm are the cylinder (also available two the coaxial annulus of cylinder replace) that is installed on either side in baggage container front side or the rear side, described arbitrary pull bar is connected with cylinder respectively, and pull bar is fixed on the front end or a side of cylinder by described steering lock spare.When needs baggage car of the present invention as car when riding, front tension bar be the center with the axis (being equivalent to steering shaft) of cylinder, be radius with the radius (being equivalent to eccentric pivoted arm) of cylinder, the front end that forwards baggage container to is also locked; Back stay is the center with the axis of cylinder, is radius with the radius of cylinder, and the rear end and the locking that forward baggage container to get final product.When needs baggage car with hand push, draw when advancing, forward and backward pull bar is turned back to baggage container one side and locking gets final product around corresponding cylinder.
For the people who is fit to different heights uses, described arbitrary pull bar adopts the telescopic structure that can be locked at the different length position.
Described baggage container has the rigidity housing, and baggage container main body and this rigidity housing are detachable structure.When arriving the destination, the user can disassemble the baggage container main body from baggage car, use more convenient.
In order to dwindle the volume after baggage car folds, described handlebar adopts accordion structure.For the ease of regulating the length of forward and backward pull bar simultaneously, and then be convenient to push away, draw baggage car, described handlebar one end after folding flexibly connects the other end and back stay flexible connection with front tension bar.
The wheel driver of baggage car of the present invention can be an electrical motor, also can be the manpower foot drive device, can also electronicly mix dual-purpose with manpower.
In order further to dwindle the volume after baggage car folds, described stretcher is detachable structure.
Described manpower foot drive device is made up of the chain sprocket drive group, change-gear set and the stretcher that are connected with trailing wheel.In order both to dwindle the volume after baggage car folds, the distance when increase is ridden again between the front and rear wheel is convenient to ride, and described chain sprocket drive group is a folding structure, and chain drum spider wherein is made up of fixed support and travel(l)ing rest, and trailing wheel is installed on the travel(l)ing rest.Can pull out travel(l)ing rest backward when riding, can pack up travel(l)ing rest forward during implementation.
The utility model compared with prior art has following advantage and beneficial effect:
(1) this multifunctional folding handcart with briefcase, baggage container etc. have the casing of rigidity housing and self-moving vehicle battery-driven car be combined as a whole, simple in structure, member is few, safety easy to use is easy to control, environmental protection and energy saving.
(2) the utility model can directly be put in office, the family, exempts stolen hardship.
(3) the utility model is when towing state, be the casing form, be adapted at various different occasions, at out of town trip, shopping and on and off dutyly from the road of family or company, can occur with riding condition again, become small vehicles---bicycle battery-driven car, thereby, have good applicability energy and market outlook.
