Description of drawings
Fig. 1 is that the box Vehicular multifunctional tail-gate of the utility model is installed in the lateral plan on the main box.
Fig. 2 is the front elevation of jacking system in the box Vehicular multifunctional tail-gate of the utility model.
Among the figure: the 1-electric capstan; The 2-main box; 3-tail-gate plate; 4-capstan winch steel wire; The 5-center shaft; 6-exchanges the double output shaft motor; The 7-transmission shaft; The 8-coupler; 9-screw mandrel group; The 10-nut connecting plate; The 12-connecting panel; The 13-track.
The specific embodiment
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing, but should not limit protection domain of the present utility model with this.
Please consult Fig. 1 and Fig. 2 earlier, Fig. 1 is that the box Vehicular multifunctional tail-gate of the utility model is installed in the lateral plan on the main box, as seen from the figure, a kind of box Vehicular multifunctional tail-gate, this box car comprises having roof box and box plate main box, multi-functional tail-gate comprises tail-gate plate 3, is fixedly installed on the electric capstan of this main box tail box top board below, the capstan winch steel wire that an end is connected with this electric capstan, the center shaft 5 that the other end hasp of this capstan winch steel wire is connected in tail-gate plate inside top and is connected with described tail-gate plate bottom.The opening and closing of electric capstan 1 control tail-gate plate, when vehicle arrives the destination, in the time of need opening tail-gate plate 3, utilize electric capstan 1 that capstan winch steel wire 4 is pulled out, the tail-gate plate is around center shaft 5 Unscrews, when needs were closed tail-gate plate 3, when utilizing electric capstan 1 that capstan winch steel wire 4 is packed up, the tail-gate plate was around center shaft 5 rotary closings.
Fig. 2 is the front elevation of jacking system in the box Vehicular multifunctional tail-gate of the utility model, as shown in the figure, the box Vehicular multifunctional tail-gate of the utility model also comprises the connecting panel 12 that is separately fixed at tail-gate plate two bottom sides, the jacking system that is arranged on main box tail box base plate top, and the track 13 that is separately positioned on the main box afterbody left and right sides, the width of the spacing of this two track 13 and connecting panel 12 is suitable;
Described jacking system comprises interchange double output shaft motor 6, transmission shaft 7, coupler 8, left and right sides screw mandrel group 9 and two nut connecting plate 10, and described interchange double output shaft motor 6 is connected with nut connecting plate 10 through transmission shaft 7, coupler 8 and screw mandrel group 9 successively.Described interchange double output shaft motor drives the nut connecting plate on the screw mandrel group by transmission shaft and coupler, and nut connecting plate is moved up and down, and described nut connecting plate is connected with the tail-gate plate by connecting panel 12, moves up and down thereby drive the tail-gate plate.Connecting panel is provided with a plurality of closed type antifriction-bearing boxs, and this antifriction-bearing box is embedded in the described track.
When tail-gate plate 3 open set level after, under the driving of jacking system, track 13 along the main box afterbody left and right sides moves up and down, a plurality of closed type antifriction-bearing boxs 14 have been installed on the connecting panel 12, antifriction-bearing box embeds in orbit, when having guaranteed the moving up and down of elevating tail gate steadily and smooth and easy, with being placed on article lifting on the tail-gate to the appropriate location, just can easily article be moved in the compartment.
Our experiments show that, the box Vehicular multifunctional tail-gate of the utility model has easy to use, safe, steady, and have the big characteristics of load carrying ability, can be placed into each position highly in the compartment by the article that car is outer, can close the compartment afterbody as the tail-gate of vehicle after finishing using, can be used for all kinds of box chassis car, box trailer, have favorable application prospect.
