The screen body is still erected on the automobile when not in use, not only is the aging of the module accelerated by daily wind and sunlight, but also the wind resistance coefficient of the erected display screen is increased in the driving process of the automobile.
SUMMERY OF THE UTILITY MODEL
To prior art's defect and not enough, the utility model provides a highway warning is with on-vehicle led display screen of collapsible lift.
The utility model provides a foldable lifting vehicle-mounted LED display screen for highway warning, which is characterized in that the foldable lifting vehicle-mounted LED display screen comprises a counterweight frame, wherein the counterweight frame is fixedly arranged on a car roof or a car rear hopper, a support is arranged on the counterweight frame, the support is connected with the lower end of the display screen through a rotating shaft, two sides of the display screen are respectively provided with a telescopic pushing mechanism, and the telescopic pushing mechanism is connected with a controller to control the telescopic pushing mechanism to stretch so that the display screen can rotate along the rotating shaft under the driving of the telescopic pushing mechanism to realize the falling/erecting of the display screen;
when the display screen needs to be used, the telescopic pushing mechanism drives the display screen to rotate along the rotating shaft so as to enable the display screen to be erected, the display screen is used for displaying induced traffic warning information related to highway traffic conditions, speed control, vehicle distance keeping and highway visibility, and is matched with a highway management department to display traffic control information so as to eliminate traffic accident potential;
when the display screen does not use, scalable pushing mechanism drive display screen rotates along the pivot so that the display screen falls to prevent that wind from blowing to the sun can accelerate the ageing and reduce the windage coefficient of vehicle of module.
Preferably, when the display screen is laid down, the display screen faces downward.
Preferably, the telescopic pushing mechanism is an electric push rod.
The utility model provides a pair of highway warning is with on-vehicle led display screen of collapsible lift opens the screen body during use and shows prompt information, folding merging protection screen body module when not using, and the screen body top of merging saves the space moreover and can load other article, and the screen body that falls when the car is marchd reduces the windage, reduces the car power consumption.
Drawings
In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the drawings needed to be used in the description of the embodiments will be briefly described below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and it is obvious for those skilled in the art to obtain other drawings without creative efforts.
Fig. 1 is a schematic structural view of a foldable lifting vehicle-mounted led display screen for highway warning provided in the embodiment of the present invention;
fig. 2 is the embodiment of the utility model provides an on-vehicle led display screen of collapsible lift state schematic diagram that falls is used in highway warning.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
The utility model provides an on-vehicle led display screen of collapsible lift is used in highway warning, including counter weight frame 1, the counter weight frame is fixed to be set up on car roof or car back fill, be provided with the support on the counter weight frame, the support is through 2 connection display screen 3 lower extremes of pivot, the display screen both sides are provided with scalable pushing mechanism 4 respectively, flexible pushing mechanism is for can be electric putter.
The telescopic pushing mechanism is connected with the controller to control the telescopic pushing mechanism to stretch so that the display screen can rotate along the rotating shaft under the driving of the telescopic pushing mechanism to realize the falling/standing of the display screen, and when the display screen falls, the display screen faces downwards;
when the display screen needs to be used, the telescopic pushing mechanism drives the display screen to rotate along the rotating shaft so as to enable the display screen to be erected, the display screen is used for displaying induced traffic warning information related to highway traffic conditions, speed control, vehicle distance keeping and highway visibility, and is matched with a highway management department to display traffic control information so as to eliminate traffic accident potential;
when the display screen does not use, scalable pushing mechanism drive display screen rotates along the pivot so that the display screen falls to prevent that wind from blowing to the sun can accelerate the ageing and reduce the windage coefficient of vehicle of module.
The utility model provides a highway warns with collapsible lift on-vehicle led display screen, screen body horizontal module withstands downwards during electric putter initial condition under general condition, and when touching the controller switch, electric putter motor function, electric putter stretches out, and the screen body is pushed up and erects, and electric putter reaches the stroke terminal, and the motor stop motion; and reversely, the electric push rod is contracted to the initial stage of the stroke, and the screen body is folded and laid down.
The telescopic pushing mechanism can be an electric push rod, the electric push rod only needs simple setting and maintenance and is good in power supply selection, and a common electric push rod is powered by 12/24/36/48VDC direct current and 220V alternating current.
