Patent number: 11529929Abstract: The present invention proposes a wiper system being capable of ensuring wiping quality for the windshields with complex surfaces. The wiper system comprises: a wiper arm (19), on which a wiper blade (12) for cleaning a surface (16) of an object to be cleaned is provided; a first electrical motor (1) driving the wiper arm (19) to swing; a second electrical motor (9); a sensor (13) measuring a parameter representing the position of the wiper arm on the object to be cleaned; a control unit (7) receiving said parameter from said sensor (13) and utilizing said parameter to control the rotation angle of the an output shaft (18) of the second electrical motor (9), such that the output shaft (18) drives rotate the wiper blade (12) under control to change the rotation angle of the central plane of the wiper blade with respect to the wiper arm. The present invention also proposes a vehicle comprising said wiper system.Type: GrantFiled: September 19, 2017Date of Patent: December 20, 2022Assignee: TAIZHOU VALEO WENLING AUTOMOTIVE SYSTEMS CO., LTDInventors: Denis Grandjean, Jian Chen, Haoyi Hong

Patent number: 10471936Abstract: The present invention discloses an assembly that can be used in windscreen wipers of vehicles and is consisting of an adapter and a nozzle structure, and also the assembling method thereof. Here the adapter presents a first adapter assembling feature (1a) and a second adapter assembling feature (1b). The nozzle structure (2) presents a first nozzle structure assembling feature (2a) and a second nozzle structure assembling feature (2b). The first adapter assembling feature and the first nozzle structure assembling feature are matched with each other to form a first connection in the form of pin-aperture between the adapter and the nozzle structure, and the nozzle structure and adapter are rotatably pre-assembled together when they are connected only be means of the first connection. The second adapter assembling feature and the second nozzle structure assembling feature are matched with each other to form a second connection in the form of snap fit between the adapter and the nozzle structure.Type: GrantFiled: January 6, 2017Date of Patent: November 12, 2019Assignee: Taizhou Valeo Wenling Automotive Systems Co., Ltd.Inventors: Bin Deng, Xu Cheng, Denis Grandjean, Shilu Chen

Patent number: 8938845Abstract: The invention relates to a liquid heating device for an automobile that comprises two independent liquid flow paths (10a, 10b) integrally formed in at least one part (1a) made of a heat-conducting material, each liquid flow path (10a) being capable of enabling a flow of liquid between a connection terminal defining an inlet and a connection terminal defining an outlet (12a, 12b), each of the connection terminals being capable of sealingly receiving a liquid supply duct or tube, and a heating means (14) thermally coupled with said part (1a) and capable of heating said part (1a) so that the liquid flowing through said flow paths can absorb the heat of said part (1a). The invention advantageously enables the very flexible use thereof for one or more systems requiring heated liquid inside a single vehicle.Type: GrantFiled: September 7, 2009Date of Patent: January 27, 2015Assignee: Valeo Systèmes d'EssuyageInventors: Denis Grandjean, Marcel Trebouet
