As used herein, the terms "first", "second", and "third", and the like, are used interchangeably to distinguish one component from another, and are not intended to signify location or importance of the individual components.

[0027] In cold regions, wiper blades often freeze to the glass. This is mainly because: when people are inside a car, they usually use the heater, which causes the temperature inside the vehicle to be above zero. The windshield, affected by the temperature inside the car, also has a certain temperature, which is above zero. Snowflakes outside will melt when they land on the warm windshield. When people leave the vehicle and the engine is turned off, there is no heater inside the car, and the temperature inside the car gradually drops. At this time, the windshield still has a certain temperature. When snowflakes land on the windshield, they will still melt and turn into water. The melted water flows down to the stationary wiper blades. When the windshield temperature drops below zero due to the external temperature, the water on the contact surface between the wiper blades and the windshield will freeze, freezing the wiper blades to the windshield and causing the wipers to stop working properly. In the background art, the method of warming up the car to melt the frozen wiper blades between the wiper blades and the windshield requires using warm air to raise the temperature of the windshield to melt the frozen wiper blades, which takes a long time. If a heating plate is directly attached to the glass to heat the frozen wiper blades, the glass will be rapidly heated and may burst.

[0028] The vehicle wiper blade thawing device provided in this embodiment is shown in FIG. Figure 1 、 Figure 2 It is mainly composed of five parts: a heat insulation seat 1, a heating plate 2, a power supply device 3, a temperature controller 4 and a control switch 5. Among them, the heat insulation seat 1 is installed on the glass where the wiper blade is parked. There are many installation methods, such as pasting, vacuum adsorption, etc. The heating plate 2 is installed on the heat insulation seat and is in direct contact with the wiper blade. The power supply device 3 is electrically connected to the heating plate 2 to supply power to the heating plate 2. The temperature controller 4 is connected in series between the power supply device 3 and the heating plate 2 to control the heating temperature of the heating plate 2. The control switch 5 is used to control whether the power supply device 3 supplies power.

[0029] See also Figure 4 、 Figure 5 Grooves or channels are arranged at intervals along the length direction on the thermal insulation base 1. The bottom surface of the thermal insulation base 1 is attached to the windshield of the vehicle. The heating plate 2 is fixedly installed on the thermal insulation base 1. The above-mentioned grooves or channels are arranged on the bottom surface of the thermal insulation base 1, or the grooves or channels are arranged in the thermal insulation base 1.

[0030] In practice, the thawing device is installed on the front windshield of a vehicle, specifically in a position corresponding to the position of the vehicle's wiper blade and having the same length as the wiper blade. The wiper blade rests on the heating plate. When the wiper blade is frozen in cold regions, turning on the control switch causes the power supply device to supply power to the heating plate, rapidly raising the temperature of the heating plate to the temperature set by the temperature controller, thereby thawing the frozen wiper blade. Because there is a heat insulation seat between the heating plate and the glass, the glass will not crack due to the rapid increase in temperature.

[0031] The groove or the channel is arranged on the heat insulation seat, and the main purpose is to absorb the change amount of thermal expansion and cold contraction.

[0032] In order to improve the heating effect and accurately heat the position, the number and position of the heat insulation seats and the heating pieces in the thawing device correspond to the number and position of the windshield wiper pieces.

[0033] Referring to Figure 3 The heating element in the heating piece can be a heating resistance wire, a heating diode or the like, and can be in a wave shape or a back-to-back shape to improve the heating area.

[0034] The above only describes preferred embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can be variously changed and modified. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
