Description

Grid mobile dimming cloth curtain device

The present invention relates to an electric side window sunshade used at a side door of a motor vehicle, in particular to the electric mobile side window sunshade, which can be driven by an electric method and has a grid-movable dimming cloth curtain with a shading function for adjusting the cloth curtain Device.

The side window sunshade is applied to the products that provide sunshade function at the side window of the side door of the motor vehicle. Existing side window sunshades include manual side window sunshades and electric side window sunshades. Among them, the manual side window sunshade is mainly fixed on the bottom or front side of the side window glass with a cloth curtain base with a cloth curtain retractor, and the cloth curtain extends beyond the hook of the movable side panel of the cloth curtain retractor After the curtain is manually stretched and unfolded, it is positioned by the hook part hooked on the rear door and window frame, and when the hook part is detached from the hook part, the curtain can be given by the curtain retractor Roll up. As for the existing electric side window sunshade, it is mainly fixed to the front position of the side window glass with a cloth curtain base with a cloth curtain retractor, and is driven by a motor set installed in the side door to move along the lateral rail The rocker pulls the cloth curtain connected to the cloth curtain retractor to automatically expand or collapse.

Although the aforementioned manual or electric side window shades have the function of providing shade by using unfolded curtains, the manual or electric side window shades only have a fixed shading performance, which is difficult to provide users with a car. Adjust the light transmittance of the light through the curtain according to the light and dark conditions and needs in the interior.

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 that can be parallel or horizontal to each other Moving and soft surface tissues, the two surface tissues each have a longitudinally or laterally extending strip portion without different light transmission properties, the two The surface tissue can be connected to at least one winding shaft unfolding and collapsing, and mechanically acts on at least one surface tissue with a control device and has at least one actuator that can be manually operated, so as to use the actuator to change the two The position of the strip part of the surface tissue is dimmed.

Although the aforementioned shading system can provide a dimming function inside the vehicle, the aforementioned existing shading system must be operated manually at close range through the actuator, and cannot be controlled remotely, and the technical means applied by the shading system are difficult to apply to electric side window shading In the curtain mechanism, there is a need for further improvement.

The purpose of the present invention is to provide a grid-movable dimming cloth curtain device, which solves that the existing shading system is manual, which is difficult to apply to the structure of the electric side window shade, and the existing shading system is not suitable for the electric side window shade problem.

In order to achieve the foregoing purpose, the grid-movable dimming cloth curtain device proposed by the present invention is used in an electric side window shade of a side door of a motor vehicle, and can be an electric driving mechanism of the electric side window shade Driven by the rocker arm in the grid, the grid-moving dimmable fabric curtain device includes: a multi-layer fabric curtain, which includes a first fabric and a second fabric woven into a shape, the first fabric and the second fabric A plurality of grids arranged in a matrix in each of their weaves, each of the first cord and the second cord has a movable edge; a cloth curtain winding mechanism including a first cord roll adjacent to and arranged in parallel A retractor and a second drape retractor, the first drape retractor is connected to the first drape, the second drape retractor is connected to the second drape; and a drape grid moving mechanism is movably connected to the The movable side of the first cord and the movable side of the second cord, and can be driven by the rocker arm, so that the first cord and the second cord are unfolded or collapsed synchronously, and the double-layered cord is in the unfolded state The window frame which can contact the side door can have a curtain dimming movement space relative to the window frame, and the rocker arm can drive the curtain grid movement mechanism to the curtain The movement of the dimming moving space changes the relative position of the matrix arrangement grid of both the first curtain and the second curtain, and adjusts the light-shielding state of the multi-layer curtain.

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 fabric can be unfolded or folded together by the rocker arm. When the multi-layer fabric is unfolded, the micro-drive of the rocker arm is used to drive the grid movement mechanism. The movement of the dimming movement space of the side door window frame can cause the relative position of the matrix arrangement of the first and second curtains to change, and the textures of the first and second curtains are opposite to each other. Partial shielding or complete shielding makes the shading of the multi-layered cloth curtain gradually increase from half-shading to the degree of shading or to the purpose of dimming for full shading. Furthermore, the grid-movable dimming cloth curtain device can be applied to electric side window sunshade cloth, providing a remote control function for the user, which is convenient for the user's operation.

The user can also reversely drive the first curtain edge plate 41A by the aforementioned operation method, so that the multi-layer fabric curtain 20 returns to the semi-shielding state.

In summary, the new grid mobile dimming cloth curtain device mainly uses a double-layer cloth curtain connected to the cloth curtain winding mechanism combined 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 fabric can be unfolded or folded together by the rocker arm. When the multi-layer fabric is unfolded, the micro-drive of the rocker arm is used to drive the grid movement mechanism. The movement of the dimming movement space of the side door window frame can cause the relative position of the matrix arrangement of the first and second curtains to change, and the textures of the first and second curtains are opposite to each other. Partial shielding or complete shielding makes the shading of the multi-layered cloth curtain gradually increase from half-shading to the degree of shading or to the purpose of dimming for full shading. Furthermore, the grid-movable dimming cloth curtain device can be applied to electric side window sunshade cloth, providing a remote control function for the user, which is convenient for the user's operation.
