Embodiment Construction

[0014] Referring to Fig. 1, the present invention mainly consists of a light handle 101, a wiper handle 102, and a base 103. The light handle 101 and the wiper handle 102 are respectively connected to the base 103. The above components and their connections are the same or equivalent to those of the prior art. . The base 103 is provided with a control circuit board slot 105 equipped with an embedded wiper control system 104, and the base 103 of the combination switch adopts an embedded integral contact plate with a translational contact structure, which is punched and formed by a whole piece of copper plate once Injection molding, all contacts move on the contact plate, so that the space utilization rate reaches the highest. Finally, after the embedded wiper control system 104 is installed, the overall volume is similar to that of a common combination switch, achieving the purpose of occupying less external space.

[0015] Referring to Fig. 2-Fig. 5, the embedded wiper control...

Abstract

The combined switch with embedded windshield wiper system is suitable mainly for Feit automobiles. It includes light handle, wiper handle, base, and slot on the base for the control circuit of the embedded windshield wiper control system. The present invention features that the embedded windshield wiper control system consists of mainly outer interface circuit, monochip computer control module, inverter, monochip computer power source, high level signal and post-wiper signal generator unit, intermittent signal generator unit, pre-water jetting signal generator unit, post-water jetting signal generator unit, slow signal generator unit, fast signal generator unit and relay. The present invention has the advantages of high time control precision, less interference on the computer signal, and prolonged life of the combined switch.

Description

technical field [0001] The invention relates to an automobile accessory, in particular to a combined switch with an embedded wiper system, which is mainly suitable for Fiat automobiles. technical background [0002] At present, the domestic combination switch is mainly composed of a light handle, a wiper handle, a base and a wiper system, and the light handle and the wiper handle are connected to the base respectively. The wiper system is to connect the pins through the movement of the mechanical contacts, and drive the external wiper intermittent through the wire harness to drive the wiper motor to work. The wiper time accuracy is poor; the contacts pass through a large current and require high requirements; the external wiper controller takes up a lot of space and has large electromagnetic interference. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned technical defects and provide a combination switch with an emb...
