Embodiment 2

[0028] Embodiment 2. The difference between this embodiment and Embodiment 1 is that the telescopic pendulum adopts a commercially available automatic telescopic rod, and the automatic telescopic rod is connected to the slider through a curved plate. Remove the two-way lead screw, screw nut slider, support rod, universal gear, screw rod, and telescopic rod structure in the first embodiment. The swing driving mechanism of the telescopic swing rod adopts an air cylinder. Each swing link is connected to a cylinder. The overall height of this structure is slightly higher.

Embodiment 3

[0029] Embodiment 3. The difference between this embodiment and Embodiment 1 is that the bevel gear set in Embodiment 1 is removed, and the left two-way lead screw and the right two-way lead screw are each connected to a stepping motor.

Abstract

The invention provides an automatic supporting and winding type sunshade of a front windshield. The automatic supporting and winding type sunshade of the front windshield comprises a left group of telescopic roller shutters and a right group of telescopic roller shutters. The key point of the automatic supporting and winding type sunshade of the front windshield is that winding shafts of the leftgroup of telescopic roller shutters and the right group of telescopic roller shutters are symmetrically arranged on the two sides of a base; the base is positioned in the position, at the bottom of the front windshield, on a vehicle body; a left lifting supporting plate and a right lifting supporting plate are limited at the top of the base in a matched manner; and the left lifting supporting plate and the right lifting supporting plate are correspondingly connected with cord fabric free ends of the left group of telescopic roller shutters and the right group of telescopic roller shutters andform a structure, which horizontally moves upwards along the windshield to support a cord fabric and horizontally moves downwards to assist the winding of the cord fabric, by means of lifting drivingmechanisms connected to the left and right lifting supporting plates. The automatic supporting and winding type sunshade of the front windshield is mounted on the front windshield in the vehicle, thelifting driving mechanisms can be of folding types and can be folded and stored to the bottom of the front windshield; and moreover, the automatic supporting and winding type sunshade of the front windshield can be automatically supported; the operation is stable and reliable; the volume is small; the mounting is convenient; the automatic supporting and winding type sunshade of the front windshield does not need to be repeatedly assembled and disassembled; and the automatic supporting and winding type sunshade of the front windshield is safe and reliable.

Description

technical field [0001] The invention relates to automobile sunshade technology, in particular to an automatic stretching and retracting sunshade curtain for sunshading the front windshield of the automobile. Background technique [0002] Along with the raising of people's living standard and popularizing of automobile, automobile becomes the necessary means of transportation of numerous families. In the field of automobile industry and auto parts, sunshade and products that ensure privacy in the car are becoming more and more important. Long-term exposure of the car to the sun will accelerate the aging of the components inside the car and bring safety hazards to driving. Moreover, prolonged exposure to the sun will also cause the temperature inside the car to rise, causing harmful substances in certain materials in the car to volatilize, endangering human health. At present, there are related automatic sunshade solutions for glass positions in the interior of the car, but ...
