Description

Mesh moving dimming cloth curtain device of electric side window sunshade

The present invention relates to an electric side window sunshade for motor vehicles, in particular, the electric side window sunshade is provided with a grid-movable dimming cloth curtain device for adjusting the light transmission state of the cloth curtain.

There are two types of side window sunshades in existing motor vehicles: manual side window sunshades and electric side window sunshades. Among them, the manual side window sunshades are based on a cloth curtain base with a cloth curtain retractor Fixed at the bottom or front side of the side window glass, the curtain extends out of the hook portion of the movable side panel of the curtain retractor, so that the curtain is manually stretched and unfolded, and hooked to the rear side by the hook portion The hooks on the door and window frames are positioned, and when the hooking part disengages from the hooks, the cloth curtain can be retracted by the cloth curtain retractor. As for the electric side window sunshade, it is fixed to the front position of the side window glass with a cloth curtain base with a cloth curtain retractor, and a motor arm installed in the side door is used to drive a rocker arm that can move along a lateral rail Pulling the curtain connected to the curtain retractor automatically unfolds or folds.

The existing manual side window sunshade or electric side window sunshade can use the unfolded cloth curtain to provide the function of shading. However, the cloth curtains of the manual or electric side window shades only have a fixed shading performance, and it is difficult to provide users to adjust the light transmittance of the light through the cloth curtains according to the light and dark conditions and needs in the car.

In order to solve the aforementioned problem that the side window sunshade does not have the function of dimming the cloth curtain, someone proposed a "shading system for vehicle interior space" as disclosed in the Chinese CN108698490A invention. The shading system mainly has two parallel or horizontal A moving and soft surface tissue, the two surface tissues each have a longitudinally or laterally extending strip portion with different light-transmitting properties, the two surface tissues can be expanded and collapsed and connected to at least one winding shaft, and The control device mechanically acts on at least one surface tissue and has at least one actuating element that can be operated manually, whereby the actuating element is used to change the position of the strip portions of the two surface tissues for dimming.

Although the aforementioned shading system can provide a dimming function inside the vehicle, the aforementioned existing shading system must be operated at close range via manually operated actuators and cannot be controlled remotely, and the shading system is only applicable to the mechanism of manual side window shades, It is difficult to directly apply to the mechanism of electric side window sunshade.

The purpose of the present invention is to provide a grid-movable dimming cloth curtain device for electric side window shades, which solves the problems that the existing shading system is manual, cannot be operated remotely, and is difficult to apply to the structure of electric side window shades.

In order to achieve the foregoing objective, the grid-shifting dimmable cloth curtain device of the electric side window sunshade proposed by the present invention is used to be installed in the electric side window sunshade at the side door of the motor vehicle, and can be the electric side Driven by the rocker arm of the electric drive mechanism of the window shade, the grid moving dimming cloth curtain device includes: A multi-layer fabric curtain, which includes a first fabric and a second fabric formed in a woven shape, the first fabric and the second fabric each form a plurality of grids arranged in a matrix in their weaves, the first fabric Each has a movable edge with the second curtain; A fabric curtain winding mechanism, which includes a first curtain retractor and a second curtain retractor arranged adjacent to and in parallel, the first curtain retractor is connected to the first curtain, and the second curtain retracts Connected to the second cord; and A curtain grid moving mechanism, which movably connects the movable edge of the first curtain and the movable edge of the second curtain, and can be driven by the rocker arm, so that the first curtain and the second curtain are unfolded or retracted synchronously The cloth curtain grid moving mechanism includes a first movable side plate, a second movable side plate and an elastic element. The first movable side plate is disposed on the movable side of the first curtain and connected to the rocker arm, the The second movable side panel is arranged on the movable side of the second curtain, the second movable side panel is sleeved on the outside of the first movable side panel, and the inside of the second movable side panel is provided with the first movable side panel Move one of the cloth curtains to adjust the light moving space, the elastic element is disposed between the second movable side plate and the first movable side plate, so that the first movable side plate can move and reset relative to the second movable side plate , And when the second movable side plate is restrained by the window frame of the side door, the driving force of the rocker arm to the first movable side plate can be combined with the elastic element, so that the first movable side plate uses the cloth The curtain dimming movement space moves relative to the second movable side plate, and causes the relative position of the matrix arrangement grid of both the first curtain and the second curtain to change, and adjusts the penetration of the double-layer curtain Light state.

Through the creation of the aforementioned grid-movable dimming cloth curtain device, it mainly uses the double-layer cloth curtain connected to the cloth curtain winding mechanism in combination with the cloth curtain grid moving mechanism to connect the rocker arm of the electric drive mechanism, so that The first curtain and the second curtain of the multi-layer curtain can be jointly unfolded or driven by the rocker arm, so that the grid-moving dimming curtain device can be applied to the electric side window shade curtain, providing remote control by the user Function, easy for users to operate.

Furthermore, in the state where the grid-movable dimming cloth curtain device is unfolded, the cloth grid movement mechanism uses its second movable side panel to be sleeved on the outside of the first movable side panel, and The second movable side panel has a cloth dimming movement space for providing movement of the first movable side panel. The elastic element is disposed between the second movable side panel and the first movable side panel, so that the first movable side panel can be opposite to The second movable side plate moves and resets, and when the second movable side plate is restrained by the window frame of the side door, the driving force of the electrically movable rocker arm to the first movable side plate can be combined with the elastic element to make the first The movable side panel moves relative to the second movable side panel by using the dimming movement space of the cloth curtain, thereby changing the relative position of the matrix arrangement grid of both the first curtain and the second curtain.
