Description

DETAILED DESCRIPTION OF THE INVENTION (Field of the Invention) The present invention relates to a door locking device for an automobile, which allows the door to be locked or unlocked from a remote location using a remote control device.

(Summary of the invention) The invention provides a door lock device for an automobile.
The vehicle door can be effectively locked or unlocked by a remote control device from a wide range of positions in front of the vehicle body and on both the right and left sides without being affected by dirt caused by thrown up mud or the like.

(Prior art and its problems) In the car door lock device whose operation is controlled by a remote control device, in order to operate the device from a remote location, it is necessary to directly operate the door lock device when getting into or out of the car. There is no need to insert the car key into the key hole and operate the lock or unlock key, and the car key will not damage the outside surface of the car door, and even when the car key cannot be inserted into the key hole due to freezing. It has the advantage that it can be operated for locking or unlocking.

By the way, when installing a light-receiving section that receives a lock or unlock optical signal transmitted from a remote control device, conventionally, the keyhole of a car door is generally used from the viewpoint of using the remote control device in the same way as a car key. near or below the
A light-receiving portion is provided within the structure of an automobile door, a hole is formed in a sheet metal at a location corresponding to the light-receiving portion, and the hole is covered with a suitable light-transmitting material.

However, with conventional methods, in order to prevent water from entering through the holes during car washing, a light-transmitting material with excellent water resistance is required, and the light-transmitting material must be sealed with sufficient sealing. ,
Moreover, it had to be installed without damaging the appearance of the door, which had the disadvantage of increasing the overall cost.

Furthermore, foreign objects such as mud and dust thrown up during driving may adhere to the outer surface of the door, and these foreign objects may adhere to the light-transmitting material, which may block the optical signal from the remote control device. This has the disadvantage that the locking or unlocking operation itself of the car door becomes defective.

Moreover, it is not preferable to form a large hole in the sheet metal of an automobile door, and as a result, the light-receiving area determined by the light-receiving part and the outer diameter of the hole becomes narrow.
Locking or unlocking cannot be performed unless the remote control device is brought close to the light receiving section, which has the disadvantage that the remote control device itself cannot be fully utilized as a remote control, and the light receiving section may be damaged if the door is deformed due to a collision, etc. There were some easy drawbacks.

(Purpose of the invention) The present invention is capable of locking or unlocking a car door using a remote control device, without being affected by the adhesion of foreign matter to the car door or damage to the car door, and by configuring it at low cost. The purpose is to be able to perform this effectively from a wide range of positions on both the left and right sides of the vehicle.

(Structure and effects of the invention) In order to achieve the above purpose, the invention has the following features:
It has a light receiving section that receives a locking or unlocking optical signal transmitted from a remote control device operated to lock or unlock a car door from a remote location, and converts the optical signal received by the light receiving section into a reception signal. a control circuit that outputs a lock control signal and an unlock control signal in response to the received signal; and a control circuit that responds to the lock control signal or the unlock control signal to move the door lock mechanism to the door lock position or the door unlock position, respectively. In the door lock device for an automobile, the light receiving section is provided at least at the end on the driver's seat side of both left and right end sides of a dash board in the vehicle body.

According to this configuration, when an optical signal from the remote control device is transmitted toward either the left or right end of the dash board, the light receiving section receives the optical signal from the front of the vehicle and through either the left or right window. Accordingly, the vehicle door can be locked or unlocked.

Therefore, there is no need to install a light receiving part inside the door structure, there is no need to form a hole or cover it with a light-transmitting material, and there is no need to consider water resistance because there is no need to splash water when washing the car. , the overall structure can be constructed at low cost. Moreover, since the light receiving section is located inside the vehicle, there is no chance that the optical signal to the light receiving section will be blocked by foreign matter such as thrown up dirt or dust, thus avoiding poor reception caused by foreign matter. can.

In addition, the optical receiver can receive the optical signal from the remote control device from any position in the front of the vehicle as well as on both left and right sides of the vehicle, so there is no need to go to the side of the vehicle door to lock or unlock. Locking or unlocking can also be performed from the front, and the range of operation is wide; for example, even if the driver's seat is parked close to a building, unlocking can be easily performed from the front side of the vehicle. , which is extremely convenient in practice.
