Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a door cock mechanism of a personal io vehicle that is equipped with
Regarding keyless entry devices that unlock doors even without a key, J
This relates to the improvement of the 5G electrical signal pattern.

The door locking mechanism of a car generally has a locking mechanism in ( ) f stages, and when closing the door, at least the driver's door, even if it is locked with a push button etc., the outer handle cannot be opened. If you close the door without doing the special operation of pulling it closed, the locked lock will be released. It is designed to prevent the danger of forgetting and locking the door in the car.However, even if you add a special operation mechanism (=4) to warn owners of this J, If you forget the key and perform that operation, it will be locked, and this fish?
There still remains the problem of forgetting the key inside the vehicle and carrying it out due to neglect.

Therefore, as a solution to this problem, a keyless dirt removal device has been proposed that unlocks the door using a BIN identification number exclusive to the owner. ing.

By the way, the keyless converter'Aff? (An example of what has been proposed in the past is !121-151774, which describes a switch f equipped with button switches for each number from 0 to 9 on the car body.
1-nit is installed, and when this switch is operated, it sends an electrical signal pattern consisting of a set of numbers 1 in a row. This is compared with the programmed PIN number, and only if it matches, the door is opened. It is configured to remove W. Therefore, according to the button switch method of this prior art, the button switch for each number must be operated (pull) several times, making it easy to press the button by mistake and making the operation complicated. It has drawbacks such as being difficult to operate and requiring a large number of B switches.

In view of the problems of the electrical signal pattern creation method based on the conventional technology, the present invention has been devised to create electrical signal patterns quickly and reliably, regardless of day or night, by operating a minimum of one switch. An object of the present invention is to provide a key 1 no entry device that provides a key 1 no entry device.

For this purpose, the device according to the present invention generates a buzzer sound at constant intervals of 1 HJ based on the operating time of a single switch installed in the vehicle body, and also controls the number of E-Rus signals accompanying this buzzer sound. The gist of the system is that it is constructed so that the electricity (ffi number pattern), in which numbers are arranged in the sum δ1, is 1'13, and this is checked against a pre-programmed password.

Hereinafter, an embodiment of the present invention will be explained in a shell (A) form with reference to the drawings. A switch means is assembled into the handle 3 or the cylinder lock 4 of the locking IA structure, as will be described later.

To explain an embodiment in which a switch means is assembled to a pull-type outer handle as shown in FIG. 2, the outer handle 3 is supported by a shaft 6S on a door side support part 5 so as to be able to hear at a predetermined angle. In addition, the spring 7 for return is biased. Therefore, a switch 8 is attached to the member 5, and an operating lever is attached to the shaft 6, which rotates as the handle is pulled back.
It is placed at 8ahNm and can be operated by pulling the outer handle 3.
The bar 88 turns on the switch 8.

Referring to FIG. 3, an example in which a slider stage is assembled to a cylinder lock will be described. A cylinder case 10 is attached to a door panel 9. l! A case cover=-11 is attached to the external protrusion of the case 1°. Further, a stepped cylindrical sleeve 12 is inserted into the case 10 so as to be movable in the direction of the axis. A return spring 15 is biased between the rear l-tube ring 14 and the key cylinder 13 can be pushed back like a button switch. Insert the key/
One end of a lever 18 is connected to a clip 17 to a rotor 16 protruding from the key cylinder 13 as a mechanism for locking and releasing the lock using a V key, and a rod 20 to the door lock mechanism is connected to the other end of the lever 18 by a holder 19. A return sublink 21 is biased between the sleeve 12 and the sleeve 12 against rotation of the rotor 16. (In the structure of the key cylinder 13 that can be pushed back as described above, the operation magnet 8b is attached to the sleeve 12 side that is integral with it, and the switch 8 is attached to the case 10 side. It is mounted so that when the cylinder 13 is pressed, it is turned on by an operating magnet 81).

45 in Figure 4, the operation system for unlocking the door with a single switch 8 is as follows.
One of them is connected to the variable valve 25, and the other is connected to the integrating circuit 2G to output a voltage signal corresponding to the time when the switch 8 is turned on, and this voltage signal is input to the generator circuit 27. The oscillation circuit 27 includes an A bare amplifier 28 and a capacitor 2.
By repeating charging and discharging of the capacitor 29, it outputs a pulse signal of a number or regular intervals according to the voltage signal from the integrating circuit 26, and this pulse signal is output to the output 1 transistor. 30, the input signal 31 is inputted to a right-handed circuit 32 and a microprocessor L tether 33.

1 setter 33 is a counter circuit 34 that measures the number of pulses, a memory circuit 35, and a memory circuit 3! ) is compared with a pre-programmed password and a comparison circuit 3G generates an output signal only when they match. The output of the comparison circuit 26/l (i+i, jdzunij) operates the actuator l-1i-ta 38 via the retransistor 37, thereby providing an unlocking effect.

Next, the operation of the keyless-keyless 1-helicopter device configured in this way will be explained using FIG. 5. First, by pulling the outer handle 3 in the embodiment shown in FIG. 2 outside the vehicle, In the example, the switch 8 is turned on by pressing the key cylinder 13.

In other words, the pulse (g) from the oscillation circuit 27 causes the buzzer 31 to sound a number of times corresponding to the 32 hours of the switch 8, and from this, conversely, the length of the on time of the switch 8 is 1.
0 can be confirmed. Therefore, when the switch-on time pattern is set to J in FIG. 5(a), a pulse signal as shown in (1)
The pulses enter the counter circuit 34 of the cell 33 and are counted, and the memory circuit 35 creates an electrical signal pattern according to the number of pulses as shown in (0).

Then, the comparison circuit 36 compares the pattern of these numbers with the PIN pattern, and only if they match, the lock is unlocked by the actuator L and I-ta 38, and the tonneau lock is released without a key to allow entry into the vehicle. It is possible (becomes j pi).

As is clear from the explanation below, according to the present invention, in the 6 type that unlocks by generating a specific electric signal pattern by operating a switch installed on the vehicle body, the switch 80 on time is set at regular intervals. The configuration is such that it is confirmed by the "bleep" sound and generates an electric signal pattern based on this on time.
Multi-layered patterns can be easily created, and short poems can be performed with the guidance of a buzzer sound. Since the ON time is determined by the sound, there is no distinction between I='i 4St-, and there is no need to concentrate on the switch 8 when operating it, and you can operate it while being aware of the safety of your surroundings. obtain. Furthermore, since one switch 8 is required for 1 minute, it is advantageous in terms of structure and ship equipment.
