Anti-pinch dustproof skylight device of automobile

Abstract

The invention belongs to the field of automobile skylights, and particularly relates to an automobile anti-pinch dustproof skylight device. The device comprises a mounting plate, a transmission shaft,a belt wheel A, a belt wheel B, a synchronous belt, a sliding pin A, a sliding pin B and the like, wherein the mounting plate is mounted on the top of a carriage. When sundries such as dusts or leaves fall on skylight glass, impurities on the skylight glass cannot be brought into a guide groove A and a guide groove B by the movement of the skylight glass, rubber curtains for shielding sundries are mounted at groove openings of the guide groove A and the guide groove B, so impurities falling on the skylight glass are difficult to enter the guide groove A and the guide groove B under the movement of the skylight glass, the sliding pin A and the sliding pin B are prevented from intensifying movement blockage due to abrasion caused by sundries falling into the guide groove A and the guide groove B, thereby an effective dustproof effect is achieved, the skylight glass is always in a smoothly opened or smoothly closed movement state, and the skylight maintenance cost caused by part abrasiondue to sundry entering is reduced.

Description

technical field [0001] The invention belongs to the field of automobile sunroofs, in particular to an automobile anti-pinch and dust-proof skylight device. Background technique [0002] The traditional car sunroof anti-pinch methods mainly include contact type and non-contact type; among them, the motor in the sunroof of the contact type anti-pinch type is equipped with a Hall sensor that monitors the motor speed and feeds back to the ECU. The non-contact anti-pinch sunroof transmits signals to the ECU through the rear external line transmitter and receiver installed on both sides of the sunroof to determine whether anti-pinch protection is needed. The principle is similar to that of an infrared anti-pinch elevator. [0003] The above two anti-pinch methods used in traditional skylights mainly rely on related electronic components and their control circuits to realize the anti-pinch function of the skylight. However, electronic components are prone to damage and failure unde...

AI Technical Summary

Problems solved by technology

[0003] The above two anti-pinch methods used in traditional skylights mainly rely on related electronic components and their control circuits to realize the anti-pinch function of the skylight. However, electronic components are prone to damage and failure under the influence of climate temperature changes and other environmental factors, resulting in Failure of sunroof anti-pinch function

In addition, during the use of the traditional car sunroof, the guide rail of the sunroof is easy to fall into debris such as dust or leaves, which will hinder the sliding of the sunroof glass in the guide rail, increase wear and tear, and cause great damage to the car sunroof. In severe cases, it will Cause the car sunroof seal to fail and cause water leakage in rainy days, increasing the cost of vehicle maintenance

[0004] In view of the above-mentioned shortcomings of the anti-pinch function of the traditional car sunroof, which is prone to failure due to the failure of electrical components and is not dust-proof, it is necessary to design a sunroof device that can realize the anti-pinch function and prevent dust without relying on electronic components.
