An electric window switch control device and system

Abstract

A control device for a power window switch includes an infrared transmitting device (11), an infrared receiving device (12), a control device (13), and a structural member (14) arranged between the infrared transmitting device (11) and the infrared receiving device (12) and configured to block an infrared signal transmitted by the infrared transmitting device (11). The infrared receiving device (12) includes a first infrared receiving unit (121) and a second infrared receiving unit (122), and the first infrared receiving unit (121) and the second infrared receiving unit (122) are controlled by movement of the structural member (14) according to an operation instruction of a user, to receive or not to receive the infrared signal, thus outputting different level signals. The control device (13) controls the power window switch according to the changes of the level signals during the movement of the structural member (14). The infrared receiving device (12) transmits different level signals when being allowed or not allowed to receive infrared signals, to achieve recognition for the operation instruction of the user, thus realizing control of the power window switch, thereby avoiding a direct contact between parts, reducing physical abrasion, and improving a service life of the control system.

Description

technical field [0001] The invention relates to the field of switches, in particular to an electric window switch control device and system. Background technique [0002] At present, a contact control system is usually used to control the electric window switch of the car, such as using a keyboard to touch carbon or gold-plated contact points on the PCB board, or a mechanical contact method. [0003] However, no matter which method is used, at least two contact points are required, and a relatively complicated mechanical structure is required to realize the contact between the two to control the switch of the electric window. In the process, the mechanical structure and contact points will cause a certain degree of physical wear, thereby reducing the problem of service life. Contents of the invention [0004] In view of this, the present invention provides an electric window switch control device and system to solve the problem of using a contact structure in the prior ar...
