Detailed Description
The present invention will be further described with reference to the accompanying drawings and specific embodiments.
Example 1: as shown in fig. 1-2, a snow and ice removing device for a license plate of an automobile comprises a shell 1, a heat conducting plate 2 and an electric heating wire 3, wherein the shell 1 is of a square shell structure, two ends of the shell are provided with holes, the heat conducting plate 2 is arranged at the outer end of the shell 1, two sides of the end are provided with connecting lugs 10, the connecting lugs 10 are of a U-shaped opening structure, the installation is convenient and rapid, and the device can adapt to the distance of an on-vehicle mounting hole which changes within a certain range, the electric heating wire 3 is arranged at the inner side of the heat conducting plate 2, the heat conducting plate 2 is tightly attached to the back surface of the license plate, the heat conducting plate 2 is of a step structure, one end of the protrusion extends out of an annular clamping table at the opening of the shell and is tightly clamped with the annular clamping table, the electric heating wire is fixed on the heat conducting plate, the heat insulating plate 5 is tightly attached to the inner side of the electric heating wire 3, the shell is fixedly connected with the shell, the insulating plate is arranged, the insulating plate can realize heat insulation, the heat is prevented from being dissipated and transmitted to an electric control device, a high-temperature area inside the device is separated from an isolated circuit part by the insulating plate 5, the high-temperature aging of the high-temperature-proof circuit is prevented, and a box cover 9 is arranged at the back side of the shell 1. The snow removing device is connected with the control switch through a lead, the license plate snow removing control switch is arranged on the automobile instrument desk, and the control switch controls the starting of the snow removing device. The snow removing device main part is inside to be arranged through the layering mode, and heat-conducting plate 2 realizes the snow removing function with the even transmission of the heat of heating wire 3 on the automobile license plate body.
Preferably, a heating wire control device is installed on the inner side of the heat insulation plate 5, the heating wire 3 is connected to the heating wire control device, and the on-off of the heating wire is controlled through the heating wire control device, so that the control is convenient and rapid.
Preferably, the heating wire control device comprises a control single chip microcomputer 6 and a relay 8, the control single chip microcomputer 6 is connected to the heating wire 3 through the relay 8, the control single chip microcomputer 6 is connected to the relay through a lead, the on-off of the heating wire is controlled through the relay, and the control is accurate and stable; the control single chip microcomputer 6 is further connected with a temperature sensor 4, the temperature sensor 4 penetrates through the heat insulation plate 5 and the heat conduction plate 2 and then abuts against the license plate, the license plate is controlled through the temperature sensor, control accuracy is improved, the phenomena that paint on the license plate drops due to overhigh temperature and deicing and snow removal cannot be achieved due to overlow temperature are avoided, and a fuse is further installed between the relay 8 and the heating wire.
The snow and ice removing device has the working principle that: according to the flow shown in fig. 3, in the diagram, T represents the initial temperature of a sampling interval (2 min), T represents the ending temperature of the sampling interval, the temperature sensor 4 feeds the detected temperature of the license plate back to the control single chip 6, and whether the temperature of the snow removing device exceeds the limit and whether the ice and snow are removed is judged according to the temperature state. When the control singlechip 6 judges that the temperature is too high, the control singlechip 6 sends a signal to cut off the power supply of the electric heating wire 3, and the power supply of the electric heating wire 3 is switched on until the temperature returns to a normal value, so that the device is prevented from being in failure due to continuous temperature rise; when the singlechip 6 judges that the snow ice blocks on the license plate are completely removed, the singlechip 6 is controlled to send a signal to cut off the power supply of the electric heating wire 3 to finish snow and ice removing work of the snow and ice removing device. When the control switch is pressed down, the singlechip 6 detects that the switch is pressed down, the temperature sensor 4 starts to work at the moment, and the singlechip 6 judges whether accumulated snow and ice exist or not according to the external temperature detected by the temperature sensor 4 so as to prevent the heating wire from being started due to misoperation; when the condition that snow is accumulated due to too low temperature is judged, the single chip microcomputer sends a signal for switching on the power supply of the heating wire 3 to the relay 8, the relay is switched on the power supply of the heating wire, and the heating wire starts to work.
