Abstract

PURPOSE:To enable releasing a lock without any use of a key by generating a signal via the pushing and pulling operation of a door handle so set as to be slightly movable back and forth, and opening a door upon the coincidence of the operation with the predetermined sequence and times. CONSTITUTION:A cushion material 42 is provided between a door handle 41 with the upper end thereof axially supported and a door 4, and the door handle 41 is made movable slightly back and forth. Then, two limit switches 21 and 22 are provided inside the door 4. When the door handle 41 is pushed, the first limit switch 21 is actuated, and the pulling of the door handle 41 actuates the second limit switch 22, respectively transmitting signals. Subsequently, the combination of a sequence for the pushing and pulling operation of the door handle 41 and each operation time is arbitrarily determined and saved in a control part. Furthermore, when the door handle 41 is operated in accordance with the determined sequence and time, a door lock is released.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to an automobile door unlocking device that can automatically unlock the automobile door by operating from outside the vehicle without using a key.

<Prior Art> Automobile doors are generally constructed so that the door lock device can be operated from inside and outside the vehicle.

Furthermore, when unlocking a door from outside the vehicle, the key is inserted into a keyhole exposed on the outside of the door and rotated.

<Problems to be Solved by the Present Invention> The following problems exist in conventional automobile door lock devices.

<B> If the door is locked with the key left inside the car or if the keyhole is frozen, it takes a lot of effort and time to open the door from outside the car, which is very inconvenient.

<Talking> Given the current situation as described above, there is a strong need for a proposal for a door lock release technique that can be easily and reliably unlocked.

<Object of the present invention> The present invention has been made in view of the above points, and an object of the present invention is to provide the following automobile door unlocking device.

<A> You can unlock the door from outside the car without using the key.
Automobile door unlocking device.

<Mouth> A car door unlocking device that makes unlocking the door easy.

<C> A highly versatile car door unlocking device.

<Structure of the Present Invention> Hereinafter, an embodiment of the automobile door unlocking device according to the present invention will be described with reference to the drawings.

<A> Overall configuration of door lock release device FIG. 1 shows an example of a door lock release device.

The door unlocking device includes a control section 1, an input section 2, and an actuation section 3.

The control unit 1 is electrically connected to the input unit 2 and the actuation unit 3, and after inputting the input signal from the input unit 2 to the control unit 1, sends a start signal to the actuation unit 3 to release the lock. It is structured so that it can be used.

Each part will be explained in detail below.

<Exposure> Control unit The control unit 1 includes a reset timer 11, a lock release relay 12, and multiple sets of amplifiers 1'3a to 13c.

14 is a 12 volt or 24 volt DC power supply,
The positive side is first connected to the reset timer 11.

Further, the reset timer 11 is connected to a lock release relay 12 and a plurality of sets of amplifiers 13a to 13c, respectively.

The reset timer 11 has a function of clearing the input of the erroneous signal after a certain period of time when an erroneous signal is input from the input section 2 to the plurality of amplifiers 13a to 13c, and the reset time can be freely set. can.

Each of the amplifiers 13a to 13c uses an IC (integrated circuit) that, when a predetermined signal is input from the input section 2, forms a relay circuit step by step in the order of the amplifiers 13a to 13c in conjunction with the unlocking relay 12.

Each of the amplifiers 13a to 13c has a plurality of switch elements inside thereof, and only when the set switch element receives an input signal, sends a signal to form a relay circuit to the lock release relay 12. The configuration is the same.

In advance, each of the amplifiers 13a to 13c is arbitrarily set to a value for forming a stepwise relay circuit in response to input signals from first and second limit switches 21 and 22, which will be described later.

This value is set using a known method.

Further, when the components constituting the control section 1 are for low voltage, a transformer for regulating the voltage to a predetermined voltage is appropriately interposed in the circuit.

<C> Input section The input section 2 consists of a first limit switch 21 and a second limit switch 22.

As an operating mechanism for the first and second limit switches 21 and 22, it is conceivable to attach them to the inside of the door handle 41 of the door 4, as shown in FIG. 3, for example.

Specifically, a cushioning material 42 such as rubber is interposed in the middle of the door handle 41 whose upper end is pivotally supported, so that the door handle 41 is slightly lifted, and the upper and lower peripheries of the operating scale 43 extending from the middle of the door handle 41 are Protrusions 44 and 45 are provided on the surface, and first and second limit switches 21 are provided on the upper and lower sides of the operating scale 43.
．． 22 respectively.

When the door handle 41 is pressed, the buffer material 42 is compressed and deformed, and a signal is sent only from the first limit switch 21, and conversely, when the door handle 41 is pulled toward this side, a signal is sent only from the second limit switch 22.

<2> Actuation part The actuation part 3 is composed of a known solenoid 31 that is actuated, for example, by electromagnetic force.

For example, in the case of a knob method in which the door is unlocked by artificially applying force to a knob connected to the door lock device, the operating portion 3 should be installed on the proximal end of the knob. The movement is installed in a position where it can be operated by the solenoid 31.

Further, if a solenoid is built into the door lock device from the beginning, the wiring from the lock release relay 12 is directly connected to the circuit of the built-in solenoid.

Although the above-mentioned door lock device is an example, in other known door lock devices, it is selected whether to incorporate the solenoid 31 or only the wiring, depending on the unlocking mechanism of these door lock devices.

In addition, a limit switch 32 for checking the door lock is installed inside the door, and a wire is connected between the limit switch 32 and the unlocking relay 12 so that the actuating part 3 operates only when the door is locked. With this configuration, malfunction of the actuating section 3 can be prevented.

<Effect> Next, the operation of the door lock release device will be explained.

<A> Input operation After pressing the door handle 41 a set number of times from outside the vehicle, for example once, pull it toward you twice, and then press it once.

The direction in which the door handle 41 is operated and the number of inputs can be set arbitrarily.

<Exposure> Formation of relay circuit By operating the door handle 41 described above, each of the first limit switch 21 and the second limit switch 2 of the input section 2 is activated.
2 sends a signal.

This signal is input to each amplifier 13a to 13C of the control section 1 and the lock release relay 12.

If the signals transmitted from the first and second limit switches 21 and 22 are accurate, a relay circuit is formed in stages.

Since the process of forming the relay circuit in stages is clear from FIG. 2, the explanation thereof will be omitted.

<C> When a relay circuit is formed step by step within the control unit 1 by inputting accurate signals from the lock release operation input unit 2, an activation signal is sent from the lock release relay 12 of the control unit 1 to the solenoid 31 of the actuation unit 3. to unlock the door.

<2> During erroneous operation If the direction or number of times the door handle 41 is operated is incorrect and an erroneous signal is input from the input unit 2 to the control unit 1, the actuating unit 3 will not operate because the stepwise relay circuit will not be formed. There isn't.

When an erroneous signal is input to the control unit 1, the reset timer 11 is started, and after a certain period of time set in the reset timer 11 has passed, all of the relay circuits are cleared and the door handle 41 is manually operated again. Operation becomes possible.

<Other Embodiments> In addition to the embodiments described above, for example, the limit switch of the input unit 2 may be attached to the door handle, or may be exposed and attached to the surface of the door, and input may be made by pressing directly with a finger.

Further, the number of stepwise formation of relay circuits is not limited to the above-mentioned embodiment, and it is sufficient that a plurality of relay circuits can be formed stepwise.

<Effects of the Present Invention> Since the present invention is as explained above, the following effects can be obtained.

<B> You can unlock the door from outside the vehicle without using the aS at all.

This is especially useful when you leave your keys in the car or when the keyhole is frozen.

<Exposure> The input operation from outside the vehicle to the input unit is as simple as pushing or pulling the door handle, making it easy to unlock the door.

<C> Since the input section is composed of multiple limit switches, and the door lock will not be released unless the individually set input order and number of inputs of the limit switches are correctly performed, even if tampered with, the door lock will not be released. The probability of release is extremely low and it is safe.

(2) Not only can it be applied to various types of automobiles, but it can also be easily applied to various types of doors for homes other than automobiles,
Full of versatility.
