A glass heating and thawing device and automobile doors and windows

Abstract

The application discloses a heating and defrosting device and automobile doors and windows, which relate to the technical field of automobile door and window design. The heating and defrosting device is used to heat the window glass in a cold environment. The heating and defrosting device includes: a heating wire, which is arranged around the vehicle The edge of the window glass has two glass heating conductive terminals at both ends; the two glass heating conductive terminals are arranged at the bottom of the window glass and connected to the vehicle power supply system; the door control button is used to control the lifting of the window glass, And the power on and off of the heating wire. The purpose of this application is to provide a glass heating and thawing device and automobile doors and windows, which adopts static communication control to realize the heating and thawing of the window glass without changing the design of the car door, and has strong durability and high reliability.

Description

technical field [0001] The application relates to the technical field of automobile door and window design, in particular to a glass heating and defrosting device and automobile doors and windows. Background technique [0002] In cold environments, the windows may freeze and prevent them from being opened. In particular, when it is cold and rainy, the windows may freeze, preventing the glass from moving and thus making it impossible to open the windows. In order to solve the problem that the automobile glass cannot be opened after being frozen at low temperature, designers in the field have carried out structural transformation on the automobile window glass. [0003] In related technologies, there are two conventional technical solutions, the first technical solution is as figure 1 As shown, the dotted line is a schematic diagram of the window glass falling to the bottom, and the solid line is a schematic diagram of the window glass rising to the top. The heating device i...

Problems solved by technology

[0005] However, the first technical solution has two disadvantages. ①The terminals of the heating device are located on both sides of the glass. When designing the car door, it is necessary to leave a space for the arrangement of the conductive terminal h3 on the door side in the lateral direction.

This requires that the bite width between the two sides of the glass and the door window frame be increased to more than 30mm, and in order to effectively block, the width of the black border on both sides of the window glass must be greatly increased, which not only affects the driving field of vision, but also The construction cost is increased; ②The conductive terminal h4 on the glass side on both sides moves up and down in the guide rail along with the glass, and the conductive terminal h4 on the glass side is always in a state of interference and friction with the guide rail during the lifting process. The electrical connection reliability of terminal h4 will be greatly reduced

[0006] However, the second technical solution also has two disadvantages: ①The door frame terminal k3 and the upper glass terminal k2 are bulky, and it is difficult to cover the leakage, which is easy to cause accidental scratches to passengers; ②The upper glass terminal k2 leaks, and the glass cannot be completely lowered to the bottom , cannot be fully lowered to the inside of the door, and cannot meet the current customer needs
