Description

A New Automobile Door Lock Control System

technical field

The utility model relates to an automobile door lock control technology, in particular to a novel automobile door lock control system which is convenient and quick to use. the

Background technique

Now cars have gone to thousands of households and have become an indispensable means of transportation in people's lives. When the current door device is unlocked, the user needs to take out the key, insert the key into the lock cylinder and turn the key, or take out the key and press the unlock button on the key. The door opening process is cumbersome and will bring some inconvenience to the user. For example, the Chinese utility model patent with the patent number of 201220404388.8 discloses a car door lock remote control key, which includes a car door lock unlock signal generator for sending a lock or unlock signal to the car door lock, and also includes a controller , a light display device and a car door lock signal receiver, the car door lock signal receiver is connected with the controller, and is used to receive the car door lock detection signal sent by the car door lock detection sensor arranged on the car door, and output the detection signal to controller. This car remote control key just has above-mentioned shortcoming, and user needs to take out key and press unlocking button to unlock car door, sends unlocking signal to door lock to complete receiving, and the door opening process is comparatively troublesome, brings certain inconvenience to user. the

Contents of the invention

The utility model mainly solves the problem that the door opening process is cumbersome when the existing car door lock device needs to be taken out and inserted into the lock core to rotate or press the key unlocking button, and provides a new car door lock control system that is convenient and quick to use. the

The technical solution adopted by the utility model to solve the technical problem is: a new type of automobile door lock control system, including a door key and a vehicle body control unit, a signal transmitting unit is provided on the door key, and a device for detecting whether the hand is placed on the door is provided. The human hand detection sensing unit on the door handle and the signal receiving unit for detecting the door key signal, the human hand detection sensing unit and the signal receiving unit are respectively connected to the vehicle body control unit. The signal transmitting unit of the car door key in the utility model transmits the key signal. When the car door key is close to the car door, the signal receiving unit receives the key signal and transmits it to the vehicle body control unit. The signal is detected and sent to the body control unit. The body control unit detects the key signal and the hand signal at the same time, and controls the door lock to unlock. The user does not need to take out the key when unlocking the car door, and only needs to bring the key close to the car door to open the car door, which is convenient and quick. the

As a preferred solution, the human hand detection sensing unit is a contact sensing sensor. As long as the human hand touches the door handle, the contact sensor can detect the signal. the

As a preferred solution, the human hand detection sensing unit is installed on the door handle. the

As a preferred solution, the vehicle body control unit is connected with the execution unit for unlocking the door lock. The execution unit is a mechanical part that controls the door lock, and the vehicle body control unit controls the mechanical part to unlock the door lock. the

The utility model has the advantages that the user does not need to take out the key when unlocking the car door, and only needs to bring the key close to the car door to open the car door, which is convenient and quick. the

Detailed ways

The technical solutions of the present utility model will be further described below through the embodiments and in conjunction with the accompanying drawings. the

Example:

A kind of novel automobile door lock control system of this embodiment, as shown in Figure 1, comprises car door key and is arranged on the vehicle body control unit 1 in the car, is provided with signal transmitting unit in the car door key, and this signal transmitting unit is radio frequency transmitting Transmitter, sending signals to the surroundings at all times. The car door is also provided with a human hand detection sensing unit 2 for detecting whether the human hand is placed on the door handle and a signal receiving unit 3 for detecting the door key signal. The human hand detection sensing unit is a touch sensing sensor installed on the door handle. The signal receiving unit is a radio frequency signal receiver matched with the radio frequency transmitter. When the key is close to the car door, that is, the radio frequency signal receiver enters the range of the radio frequency generator, the radio frequency signal receiver receives the signal. The hand detection sensing unit and the signal receiving unit are respectively connected to the vehicle body control unit, and the vehicle body control unit is connected to the execution unit 5 for unlocking the door lock.

The working process of this embodiment is: when the car door key is close to the car door, the signal receiving unit receives the key signal and transmits it to the vehicle body control unit; unit, the body control unit detects the key signal and the hand signal at the same time, and controls the execution unit to unlock the door lock. the
