  • Patent number: 11718002
    Abstract: The invention relates to a technical field of car roller shutter door production, in particular to a method for manufacturing a car roller shutter door. A single film piece is firstly vacuum formed into a desired shape, and then rubber is injected into the film piece after vacuum forming, so that the rubber and the film piece are integrally formed to form a single roller shutter strip, and then a required number of single roller shutter strips are placed and laminated on a flexible substrate in an integrated and orderly manner to form a car roller shutter door. Each of roller shutter strips is independent of each other and does not interfere or affect each other, which improves flexibility of the car roller shutter door. Compared with long strips of whole film sheet on the car roller shutter door in the prior art, each of film pieces of the present invention is independent of each other and does not have defect of easy fracture of the whole film sheet, which makes service life long.

  • Publication number: 20220097628
    Abstract: An automotive ornament, including a circuit board, a substrate, a light-emitting element, a surface decoration layer, and a pressure sensing element, is provided. The substrate is disposed on the circuit board. The light-emitting element is disposed between the circuit board and the substrate, and the light-emitting element is electrically connected to the circuit board. The surface decoration layer wraps the substrate. The surface decoration layer covers the pressure sensing element. The pressure sensing element is electrically connected to the light-emitting element through the circuit board, and pressure sensing of the pressure sensing element causes the light-emitting element to emit light, vibrate, or feedback sound.

  • Publication number: 20220097627
    Abstract: An automotive ornament including a substrate, a texture layer and a transparent layer is provided. The substrate has a first surface and a second surface opposite to the first surface. The texture layer is located on the first surface, wherein the texture layer includes a texture pattern. The transparent layer extends from a top surface of the texture layer to cover a sidewall of the texture layer and a sidewall of the substrate. The transparent layer covers the texture pattern, and the texture layer has a degree of stretching less than the transparent layer. A manufacturing method of automotive ornament is also provided.
