DETAILED DESCRIPTION OF THE INVENTION The above invention provides an automobile door that is provided with an outside handle at the rear end of the door body and is locked by approaching the door from the outside of the vehicle with a key plate. The present invention relates to a locking device.

[Sub] U Log - It has been known in the past for automobile doors to have a so-called vertical outside handle device 2 disposed at the rear end portion 1a of the door body 1, as shown in Fig. 4, for example. ing.

Specifically, the rear edge 3a of the door outer panel 3 of the door body 1 has a recess 3 for accommodating the outside handle 4.
b is formed, and under normal conditions, this outside handle 4 is set to be on the same plane as the door outer panel 3 and form a part of the rear end portion 1a of the door body 1. is rotatably attached to a shaft 5a of the base bracket 5 along the downward direction of the road via a pair of upper and lower arms 4a, 4a.The pace bracket 5 is fixed to the door outer panel 3 with bolts 5b. A handle lever 4b extends from the outside handle 4, and a sub-lever 6, which is formed with an operating arm portion 6a that engages with the lever 4b, is rotated by a pin 7 on the base bracket 5. A handle rod 8 (not shown) is attached to the free end of the sub-lever 6 to unlatch a door lock (not shown).

Furthermore, a return spring 9 is attached to the shaft 5a of the base bracket 5 to return the outside handle 4 to its normal state.

rotated in the direction. Then, a door lock (not shown) is unlatched by the handle rod 8, and the door is opened.

Conventional products of this kind include 1, for example, ``HONDA BALLADE, published by Honda Motor Co., Ltd., June 1982''.
There is something like the one described in the "Service Manual Maintenance Edition".

However, for automobile doors equipped with such conventional vertical outside handle devices, in order to lock the door from outside the vehicle, the first step (not shown) is to lock the door from outside the vehicle. There is a method of locking by inserting a key plate into the key cylinder, but this method is cumbersome to insert and has difficulty in operability.A second method is to lock using a keyless locking device.

In other words, there is a method of locking the door by pressing the lock knob on the inside of the door with the door open and rotating the outside handle 4 in the direction of arrow A to close the door. Since the direction of rotation and the direction of door closing are completely opposite, it is very difficult to operate.

In this case, there is a problem in that the key plate may be left behind in the vehicle.

In order to solve these conventional problems, this invention for fortune-telling provides an automobile door in which an outside handle is provided at the rear end of the door body and rotates around an axis along the downward direction of the road. , a locking device for an automobile door that operates and locks the door by approaching the door from the outside of the vehicle with a key plate capable of starting the engine, wherein the key plate is provided with a detection section; The vehicle door locking device is characterized in that it is provided with a sensor that detects the approach of a detection portion of a key plate, and further provided with an actuator that locks the door lock based on a signal from the sensor.

According to this method, when locking the door from outside the vehicle, the key plate is moved closer to the vehicle body. Then, a sensor installed on the door side detects the detection part provided on the key plate, and this signal is input to the actuator.
This actuator locks the door.

In this way, it is not necessary to insert the key plate into the key cylinder, and the door can be locked very easily without using a keyless locking device. Furthermore, since the key plate is used for locking, it is possible to prevent the key plate from being left behind inside the vehicle.

Master of craftsmanship Hereinafter, this invention will be explained based on examples.

1 to 3 are diagrams showing one embodiment of the present invention.

First, to explain the structure, reference numeral 11 in the figure is a door body of an automobile door, and a rear end portion 11a of this door body 11 has a
A so-called vertical outside handle device 12 is provided.

Specifically, a recess 13b for accommodating an outside handle 14 is formed in the rear end edge 13a of the door outer panel 13 of the door body 11, and in a normal state, this outside handle 14 is approximately the same as the door outer panel 13. - It is a flat surface and is set to form a part of the rear end portion 13a of the door body 11. This outside handle 1
4 is a pair of upper and lower arms 14a.

It is rotatably attached to a shaft 15a of the base bracket 15 along the road downward direction via a shaft 14a. This base bracket 15 is attached to the door outer panel 1 with bolts 15b.
It is fixed at 3. Further, a handle lever 14b extends from the outside handle 14, and a sub-lever 16, which is formed with an actuating arm portion 16a that engages with the lever 14b, is attached to the base bracket 15 with a pin 1.
7, it is rotatably mounted. This subleper 1
A handle lever 18 (not shown) for unlatching a door lock is attached to the free end of the handle 6. Further, a return spring 1 is attached to the shaft 15a of the base bracket 15 to return the outside handle 14 to its normal state.
9 is installed.

In addition, the key plate 20 that starts the engine of the car
A reflector 20b that reflects light as a detection section is attached to the head 20a. On the other hand, on the door side, a photosensor 21 is arranged as a sensor for detecting the approach of the reflector 20b of the key plate 20. This photosensor 21 is arranged such that a light emitting part 21a and a light receiving part 21b are held at the tip part 22a of a holder 22 which is fixed to a base bracket 15 with a screw 23. It is connected to an actuator (not shown). This actuator is configured to lock the door in response to a signal from the photosensor 21.

It is also set so that a locking sound is generated when the device is locked.

On the other hand, the outside handle 14 has the light emitting section 21
An opening 14c for light passage is provided at a position corresponding to the light receiving portion 21b and the light receiving portion 21b.

Next, the operation of the locking device having such a configuration will be explained.

To lock the door from outside the vehicle after closing the vehicle door, insert the reflector 20b provided on the head 20a of the key plate 20 into the opening 14c of the outside handle 14 as shown in FIG. guess. Then.

The light from the light emitting part 21a of the photosensor 21 is reflected by the reflector 20b of the key plate 20 and received by the light receiving part 21b, whereby the approach of the key plate 20 is detected, and this signal is input to the actuator.

This actuator locks the door.

In this way, the door can be locked simply by bringing the key plate 20 close to the outside handle 14, so there is no need to insert the key plate 20 into a key cylinder or use a keyless lock device as in the past. Since there is no door lock, it is extremely easy to lock the door. Further, since the key plate 20 is locked from the outside of the vehicle, there is no chance of the key plate 20 being left behind inside the vehicle. Moreover, since the key plate 20 only needs to be placed against the opening 14c of the outside handle 14, the opening 14c serves as a landmark, so that the locking operation can be easily performed. Furthermore, when the door is locked, a locking sound is generated, so the operator asks if the door has been locked.

It is possible to confirm whether or not the locking operation is performed, and the locking operation can be performed reliably.

In the above example, a photosensor that uses light is used as a sensor, but it is not limited to this.In addition to light, various other sensors such as sound, radio waves, radioactivity, natural frequency of 2 weights, 2 colors of materials, and shapes can be used. Means can be used to detect the approach of the key plate. Further, in the above embodiment, the sensor is disposed at the handle body, but the sensor is not limited to this, and it goes without saying that the sensor may be disposed at other locations.

As described in detail, according to the present invention, when a car door having a so-called vertical outside handle device is locked, a key plate is brought close to the door, and this approach is detected by a sensor. Since the door lock is activated by detection and activation of the actuator, there is no need to insert the key plate into the key cylinder, and there is no need to use a keyless locking device, making it very easy to lock the door. At the same time, it also has the practical effect of preventing the key plate from being left behind in the vehicle.
