Abstract
The utility model is related to the body frame structure for automotive of centre fold, including front-wheel, front axle, holder, rotary shaft, vehicle frame, cover board, mounting base, trailing wheel, in the utility model, under use state, front-wheel, trailing wheel passes through holder, vehicle frame forms normal riding condition from front to back, when needing to fold, handle portion is shunk first, then vehicle frame is rotated 180 ° along rotary shaft, front-wheel is then turned back under the drive of holder to the cavity of vehicle frame front, since vehicle frame front cavity is sealed with the slit-like through-holes on cover board by the plastic parts engaged, preceding wheelchair can be smoothly through slit-like through-holes, to which the vehicle frame connected between front-wheel and trailing wheel be folded, reduce the size after folding, it is easily portable.Therefore have the characteristics that convenient and practical.
Description
Technical field
The utility model is related to mechanical fitting field, the specially intermediate body frame structure for automotive turned down.
Background technology
Electric vehicle, i.e. electric drive vehicle also known as electricity are driven.Electric vehicle is divided into alternating current electric vehicle and DC electric car.Usually
The electric vehicle said is, by components such as controller, motors, to convert electrical energy into mechanical energy movement using battery as energy source,
To control the vehicle that size of current changes speed.
First electric vehicle was manufactured in 1881, and inventor France engineer Gustaf Te Lufu, this is
One with the tricycle that lead-acid battery is power, it is driven by direct current generator, and even to this day, electric vehicle has had occurred huge
Variation, type are also varied.Electric bicycle functionality advantage once inexpensive with its, convenient, environmentally friendly, by city middle and low income
Stratum favors.The electric bicycle of China is launched from developing middle nineteen nineties in last century small lot, until 2012
Production and selling since year is in the impetus to increase substantially year by year always.Due in great demand, Chinese electric bicycle in recent years
Market is always maintained at great-leap-forward growth.
The structure of whole electric vehicle is very simple, and basic unit is exactly vehicle frame, plastic, damping, battery, controller, motor.Vehicle
The quality of frame is particularly critical, and many users less take notice of the quality of vehicle frame, because this part is difficult to observe.But the product of vehicle frame
Upright to connect the security performance for determining vehicle, vehicle frame gets rusty in order to prevent needs the technique for being referred to as electrophoresis, many vehicle frames
Manufacturer only simply sprays pitch-dark without electrophoresis for control cost.When test run, then emergency brake of running at high speed is seen
Whether vehicle frame there is double swerve, if shaken terribly, illustrates that vehicle frame quality is unqualified, there are security risks.Damping is shadow
The critical component of comfort is rung, it is divided into preceding damping and rear damping.The selection of battery is also that highly important, good battery can be with
Substantially reduce use and the maintenance cost in consumer's later stage.
Folding type battery vehicle is that handle portion is folded to vehicle frame mostly at present, therefore total length or long is not portable
Band, use scope have certain limitation.
Utility model content
The utility model, and can be by the front and back wheel of battery truck exactly in view of the above problems, provide a kind of telescoping handle
Fold into the intermediate body frame structure for automotive turned down of juxtaposition.
The utility model is achieved through the following technical solutions above-mentioned purpose：
The body frame structure for automotive of centre fold, including front-wheel, front axle, holder, rotary shaft, vehicle frame, cover board, mounting base, trailing wheel,
It is characterized in that front-wheel is arranged by front axle on holder, holder is connect by rotary shaft with vehicle frame, and vehicle frame front is arranged to cavity,
Rear portion has the protrusion vertical with front cavity, vehicle frame front upper to be provided with cover board, and vehicle frame front medial location is provided with
Slit-like through-holes, corresponding position is again provided with slit-like through-holes on cover board, is set by mounting base below the protrusion at vehicle frame rear portion
It is equipped with trailing wheel.Front-wheel is directive wheel.Trailing wheel is carrying roller.Vehicle frame front cavity and the slit-like through-holes on cover board pass through the modeling engaged
Glue part is sealed.
In the utility model, under use state, front-wheel, trailing wheel are made up of normal shape of riding holder, vehicle frame from front to back
State first shrinks handle portion when needing to fold, and vehicle frame is then rotated 180 ° along rotary shaft, front-wheel is then in holder
It turns back under drive to the cavity of vehicle frame front, since vehicle frame front cavity and the slit-like through-holes on cover board pass through the plastic cement that engages
Part is sealed, and preceding wheelchair can be smoothly through slit-like through-holes, to roll over the vehicle frame connected between front-wheel and trailing wheel
It is folded, the size after folding is reduced, it is easily portable.Therefore have the characteristics that convenient and practical.
Description of the drawings
Fig. 1 is the utility model overall structure diagram, and Fig. 2 is the utility model folded state schematic diagram, wherein：
1-front-wheel, 2-front axles, 3-holders, 4-rotary shafts, 5-vehicle frames, 6-cover boards, 7-mounting bases, 8-trailing wheels.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
5 structure of vehicle frame of centre fold, including front-wheel 1, front axle 2, holder 3, rotary shaft 4, vehicle frame 5, cover board 6, mounting base
7, trailing wheel 8, it is characterised in that front-wheel 1 is arranged by front axle 2 on holder 3, and holder 3 is connect by rotary shaft 4 with vehicle frame 5, vehicle
5 front of frame is arranged to cavity, and rear portion has the protrusion vertical with front cavity, 5 front upper of vehicle frame to be provided with cover board 6, vehicle
5 front medial location of frame is provided with slit-like through-holes, and corresponding position is again provided with slit-like through-holes on cover board 6, and 5 rear portion of vehicle frame is dashed forward
Go out beneath portions and trailing wheel 8 is provided with by mounting base 7.Front-wheel 1 is directive wheel.Trailing wheel 8 is carrying roller.5 front cavity of vehicle frame with
