Vehicle backstop sliding window assembly

Abstract

The invention relates to a vehicle backstop sliding window assembly. The vehicle backstop sliding window assembly comprises a whole window framework, fixed glass, an upper guide rail, a lower guide rail and a sliding window; defrosting heating lines are arranged on the fixed glass and the sliding window; the sliding window is provided with a cable rolling device; the cable rolling device comprisesa box, a rolling unit, a first electric conduction device and a second electric conduction device; the box comprises a bottom box body and a box cover; the bottom box body is arranged on the edge ofthe sliding window; the box cover is detachably installed above the bottom box body; the rolling unit is fixed inside the bottom box body; the first electric conduction device is arranged on the rolling unit; the rolling unit is wound with a first cable; the output end of the first cable is electrically connected with the first electric conduction device; the second electric conduction device is fixed to the inner surface of the box cover and in electric contact with the first electric conduction device; and a second cable is arranged between the second electric conduction device and the defrosting heating line of the sliding window for electric connection. The sliding window can ensure electrifying work of the defrosting heating line of the sliding window no matter in which state.

Description

Technical field: [0001] The invention relates to the technical field of automobile windows, in particular to an automobile rear shield sliding window assembly. Background technique: [0002] In the case of a large temperature difference between the inside and outside of the car, the surface of the car body glass is prone to fogging, which affects the driver's vision. When parked outdoors, the surface of the car body glass will condense thin ice or have ice and snow deposits, which will block the driver's sight. Before normal driving, usually It takes a certain amount of time for the driver to remove snow and ice on the glass surface. In order to solve this problem, the method of making silver paste heating lines on the window glass is usually adopted, especially on the rear windshield of the car. Hotline technology defrost. [0003] However, the silver paste heating line technology needs to set the bus feed point on the glass, and then connect the feed point through the veh...

AI Technical Summary

Problems solved by technology

And some vehicles, such as the rear windshield of pickup trucks, are mostly composed of fixed glass and sliding glass. If the silver paste heating line is made on the sliding glass and requires it to have the defrosting function, there will be the following problems: sliding The window will drive the cable to move at the same time during the movement, so the cable is very easy to be bent and damaged, and a complicated structure needs to be designed for the cable routing. The fixed glass is provided with an electrical connector connected to the power supply of the body, and the sliding glass is provided with an electrical contact piece that matches the electrical connector. When the sliding glass moves to the fully closed position, the point contact piece on the sliding glass and the electrical connector electrical connection between

However, the device is in a power-off state during the movement of the sliding glass, so the heating wire on the sliding glass cannot be energized at any position for defrosting.

[0004] In view of the problem that the conductive film on the sliding glass cannot be energized at any position for defrosting, US20110147153 discloses a retractable cable assembly for supplying power to the defrosting heating element of the sliding window of a vehicle, and the cable is installed on the fixed glass The retractor is equipped with an electrical connector on the sliding glass. The cable between the electrical connector and the cable retractor can be freely retracted in the guide rail through the cable retractor. There are components connected to the vehicle power supply inside the cable retractor. Therefore, whether the sliding glass is closed, open or partially open, it can be energized for defrosting

However, the cable retractor and electrical connector of the device are separately arranged on the fixed glass and the sliding glass, and the cables between them move in the guide rail together with the sliding glass, so the sliding guide rail and the sliding glass are designed on the same level, so that The structural design is only suitable for use on non-flush or split-level rear screen sliding windows, but it is still easy to bend and damage the cables on flush rear screen sliding windows with curvature changes in the guide rails, and it needs to slide on the rear screen Installing the cable retractor and electrical connector on the window will increase the structural complexity and production cost of the rear sliding window
