Vehicle and sunroof assembly thereof

Abstract

The invention provides a vehicle and a sunroof assembly thereof. The sunroof assembly comprises a sunroof, a sunroof driver, an acceleration sensor, a supporting block, a supporting block driver and a control unit, wherein the acceleration sensor is used for detecting the acceleration of the sunroof; the supporting block driver is connected with the supporting block, and is used for driving the supporting block to move between a resisting position where the supporting block resists the sunroof and a separation position where the supporting block is separated from the sunroof; and in the sunroof closing process, the supporting block driver drives the supporting block to move to the resisting position to increase acceleration change when the sunroof pinches objects, and the control unit can stop the sunroof from being closed and move towards an opening direction according to the magnitude of the acceleration of the sunroof. Therefore, in the sunroof closing process, the temporary rigidity of the sunroof is increased by enabling the supporting block to resist the sunroof, the acceleration change of the sunroof when the sunroof pinches the objects is increased, therefore the control unit can stop the sunroof from being continuously closed in time and the situation that the sunroof pinches hands is effectively prevented from occurring.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a vehicle and a sunroof assembly thereof. Background technique [0002] At present, many technologies previously defined as high-end configurations in the field of automotive technology have become standard configurations of ordinary cars, such as the sunroof assembly of a car. [0003] The sunroof brings pleasant driving and riding experience to the driver and passengers, however, the anti-pinch effect of the sunroof has been unsatisfactory. [0004] The working principle of the sunroof anti-pinch is mostly through the acceleration sensor to detect the acceleration generated by the resistance encountered during the movement of the sunroof. Only when the acceleration reaches a predetermined value, the sunroof closing action needs to be stopped immediately, otherwise the sunroof will continue to close until it is completely closed. This just has concerns about people's safety du...

AI Technical Summary

Problems solved by technology

[0006] In actual use, often at the moment when the skylight clamps the hand, due to the insufficient strength of the skylight, the clamped object (especially the relatively soft hand) cannot cause enough resistance to the moving part of the skylight in a short time, resulting in acceleration The acceleration value of the sunroof detected by the sensor is relatively small, and the movement of the sunroof cannot be stopped at the first time, resulting in serious pinching of the hand

[0007] However, on the premise of satisfying the safety of the vehicle, increasing the strength of the vehicle sunroof roof (made of steel plate) only to prevent hand pinching not only increases the manufacturing cost of the vehicle, but also high-strength steel plate is difficult to form, increasing the Difficulty of the manufacturing process

[0008] In addition, the roof of the sunroof of the existing vehicle is formed by the outer plate and the inner plate, so the outer root of the sunroof cannot be treated with anticorrosion, so it is easy to cause local corrosion of the sunroof
