Description
Technical field
The present invention relates to a kind of assisting overturn device after automobile on tailgate.
Background technology
At present, the rear tailgate of goods carrying vehicle container generally adopts and the lower end of rear tailgate is hinged on container lower end, and then after manual unlocking, rear tailgate is closed by tailgate and manual locking, also has the structure that rear tailgate is opened automatically by oil cylinder etc.But the effect that so rear tail-board structure plays is only limitted to be closed in compartment and open, convenient unloading.The help played above unloading goods is less.Often comparatively requiring great effort when getting in stocks, needing independent hydraulic elevating platform to help.
In order to overcome the problems referred to above, rear tailgate is designed to move up and down by we, tail plate device after a kind of double-layer plate type road obstacle clearing vehicle disclosed in Chinese patent ZL201120556056.7, tailgate after tailgate and second after rear tail plate device being designed to comprise first, after first, after tailgate and second, tailgate is hinged, first rear tailgate and the second rear tailgate can be elevated, tailgate open second after decline after, like this, tail plate device is just equivalent to a lifting table, goods can be shifted onto on rear tailgate, then after, tailgate rises, then goods is advanced compartment.After getting in stocks, rear tail plate device is overturn, for compartment is closed.
Like this, design one lifting horizontal support structure and suitable switching mechanism become our the first-selected problem needing to consider.
Turning control mechanism disclosed in Chinese patent ZL201120556056.7 comprises two oil cylinders, two oil cylinders are hinged respectively at the both sides of wrecker flat board, the push rod of two oil cylinders is hinged respectively at the both sides of the first rear tailgate, upset is realized by two oil cylinders, such oil piping system complex structure, cost is high, needs the dynamics of oil cylinder larger.
Summary of the invention
For existing problem, the object of the present invention is to provide that a kind of cost is low, tailgate assisting overturn device after the automobile of labour-saving.
To achieve these goals, technical scheme of the present invention is: tailgate assisting overturn device after a kind of automobile, comprise rear tailgate body, it is characterized in that: the rear lower surface of described rear tailgate body is provided with supporting seat, one end of back-up block by pin hinges on supporting seat, the rear lower surface of described rear tailgate body is also provided with extension spring, one end of described extension spring is connected on rear tailgate body, the other end is connected with the end of connecting rod, one end that described connecting rod is connected with extension spring is connected with pull bar by pin, the described connecting rod other end is connected with back-up block, turning rack is provided with at the rear of rear tailgate body, pull pull bar, described back-up block reaches below turning rack.
Adopt such scheme, as shown in Figure 1, after we adopt single oil cylinder lifting to control, tail plate device rises and declines, when on unload goods time, in the raw, back-up block, under the effect of connecting rod, is in contraction state in extension spring, can not interfere with turning rack, freely rising and declining of rear tail plate device can be realized.
When on unload goods after, need rear tailgate to overturn, make compartment close, now, pull pull bar, spring elongates, connecting rod follows pull bar to move, connecting rod drives back-up block to stretch out, and back-up block reaches below turning rack, and lifting mechanism continues action upwards, back-up block is reversed frame to be stopped, rear tailgate is just reversed, until vertical state, then the locking of the catch gear of rear end, rear tailgate compartment just can.Now back-up block is separated with roller, and spring self-return, initial position got back to by back-up block.
In technique scheme: described turning rack comprises transverse beam, longitudinal beam is provided with at the middle part of the side of transverse beam, the end of described longitudinal beam is provided with two rollers and installs journal stirrup, two rollers are installed journal stirrup and are symmetrical set, install between journal stirrup at two rollers, by bearing pin, roller is installed, when pulling extension spring, described back-up block reaches below roller.Transverse beam is arranged on vehicle frame, and back-up block props up roller and rear tailgate is overturn, and back-up block coordinates with roller, avoids very stiff and demanding phenomenon, and device is not fragile.
In such scheme, the end of described longitudinal beam is provided with end plate, and described roller is installed journal stirrup and is arranged on end plate.More convenient like this installation.
In such scheme: be connected with reinforced rib between described longitudinal beam and transverse beam.Increase the Joint strenght between longitudinal beam and transverse beam.
In such scheme, the lower surface of described rear tailgate body is provided with pull bar fixed block, and described pull bar fixed block is provided with the through hole passed for pull bar, and described pull bar is provided with bending part away from one end of extension spring.Pull bar fixed block is set, facilitates steady brace, pull bar is not sling.Pull bar arranges bending, handled easily.
The invention has the beneficial effects as follows: structure of the present invention is simple, easy to use, by the combined action of back-up block and turning rack, more laborsaving when making tailgate upset after realization, single oil cylinder can be adopted just can to complete rotary movement, and cost is low.
