Detailed ways

Below in conjunction with accompanying drawing, technical scheme of the present utility model is described in detail:

As shown in FIG. 1 , the vehicle-mounted mobile warning sign includes: a warning sign and a car body 5 . The warning sign includes a concave-convex substrate 4 and a base 1 inlaid with magnet blocks. The concave-convex substrate 4 is fixed on the base 1 inlaid with the magnet block. The warning sign is adsorbed on the dolly body 5 through the base 1 inlaid with magnet blocks, which makes the warning sign moveable by pushing the dolly body when the warning sign needs to be used.

There is a reflective film 3 made of reflective material on the surface of the concave-convex substrate 4, and a warning pattern 2 made of luminescent material is arranged on the reflective film 3. The upper surface of the dolly body 5 is equipped with a solar panel 7, and the dolly body 5 is equipped with light-emitting diodes 6 around it. The reflection of natural light by the reflective film 3 makes the warning pattern 2 made of luminescent material more eye-catching. The light-emitting diode 6 is powered by a storage battery, and the solar panel 7 converts natural light into electric energy to charge the storage battery.

The trolley body 5 includes a controller for controlling the movement of the trolley body, and the block diagram of the controller is shown in FIG. 2 . The controller includes: single-chip microcomputer, command transmitter, display, motor drive control circuit, encoder, motor, LED. The input terminal of the motor drive control circuit is connected with the single chip microcomputer, and the output terminal is connected with the motor. The input terminal of the encoder is connected to the motor, and the output terminal is connected to the single-chip microcomputer. The command transmitter, the display and the LED are respectively connected with the single chip microcomputer.

The single-chip microcomputer generates PWM according to the instruction transmitted by the instruction transmitter, and the motor drive control circuit obtains the motor driving signal according to the PWM output by the single-chip microcomputer. The encoder is a rotary sensor that converts the rotational displacement of the motor into a series of digital pulse signals. The single-chip microcomputer uses the digital pulse signal output by the encoder as the PWM feedback signal, corrects the output PWM, and then adjusts the rotational displacement of the motor. The display shows the moving direction information of the trolley body. LED is the light-emitting diode 6 installed on the dolly body 5, which flickers when the dolly body moves to play a warning role. The command transmitter can be a keyboard, through which the user inputs the command to move the trolley body; it can also be a wireless remote controller, which sends out a movement command by operating the wireless remote control, and the movement command enters the single-chip microcomputer through the wireless communication port of the single-chip microcomputer. The controller arranged in the car body makes the car body move flexibly.

In summary, the vehicle-mounted mobile warning sign described in the utility model combines the warning sign with the trolley body, and realizes the function of the warning sign automatically reaching the designated position by controlling the movement of the trolley body; it is not only convenient to use, but also The danger that people directly place the warning sign is avoided.
