Abstract

The invention belongs to a touch lock device for a door of a car and particularly to the device which can achieve unlocking and locking of a door of the car by touching of a button point on a handle decoration cover. The device comprises a handle decoration cover, a touch chip module, a switching control module and an intelligent key system, wherein the touch chip module senses capacitance fluctuation caused by the touching of the touch button point of the handle decoration cover and transmits an alternating electrical signal to the switching control module, the switching control module is connected with a key free entering sensing module, when signals of the touch chip is input, the switching control module is put through and output a control signal to the key free entering sensing module, the key free entering sensing module determines that a driver with the intelligent key enters a sensing area and outputs the control signal to a locking / unlocking driving unit to achieve a locking / unlocking action of the door of the car, or the switching control module outputs the control signal directly to the locking / unlocking driving unit to achieve the locking / unlocking action of the door of the car. The device has the advantages of being accurate in sensitivity, high in safety performance, attractive in appearance, practical and the like.

Description

[0001] technical field

[0002] The invention belongs to a control locking device for a car door, in particular to a device for unlocking and locking a car door by touching a key point on a handle trim cover.

[0003] Background technique

[0004] The smart keyless system is the latest technology in the automotive industry. It uses RFID technology to identify legal keys. The car only responds to legal keys, such as opening the door, ignition, etc.; for uncertified or illegal keys, then No response is made. The smart key system in the prior art includes at least one keyless entry sensor module, which makes it and the antennas attached to the smart key communicate with each other through wireless information exchange and code verification, and then confirm that the driver with the smart key has Entering the sensing area, and at the same time, after receiving the effective touch electrical signal input, the keyless entry sensing module can be triggered to output a power signa...
