The present invention relates to an electronic key slot device, and more particularly, to an electronic key slot device capable of inserting / exporting an electronic key by sliding it into a slot and charging an electronic key and charging a battery.

In general, an automobile includes an engine that provides driving power to a power transmission unit connected to a driving wheel. The engine can be started by driving the starting motor.

The starting motor is driven by receiving an electric supply by inserting a car key into a car key hole installed inside the car to perform a rotation operation.

In recent years, an electronic key has been introduced to enable the driver's own authentication of a vehicle, to start the vehicle, and to make an emergency start when an abnormal condition occurs in the vehicle.

The electronic key exchanges electrical signals to an electronic control system such as an ECU in the interior of the vehicle, and enables the vehicle to be started when the information stored in the electronic key matches the information stored in the electronic control system.

An electronic key for this purpose is known from "German Patent Application Publication No. 19814964".

In the German patent, a driving qualification signal is generated by fingerprint detection of a qualified individual. In this case the automation member is used in the form of a check inserted into the slot next to the rocking switch or in the rotary switch.

In addition, the rotary switch and the rocking switch include a sensor for the fingerprint, and can be activated or rotated by a pressing operation between various switching positions. Accordingly, various functions of the automobile engine are controlled.

Such a known German patent requires not only the rotation or pressing operation of the switch but also to provide a fingerprint at the place where the sensor is placed, in addition to the insertion operation of the automation member, and this operation is complicated and difficult to implement.

On the other hand, the description of the above electronic key is known in "German Patent Application No. 195 04 991, title of the invention: vehicle start switch".

The German known patent provides a shaft for completely inserting an identification card in the rotary handle. Insertion in this manner is possible only in the first position of the rotary handle. The rotary handle starting from this position can be displaced to various other rotary positions by the insertion of a card which controls various functions of the engine.

Therefore, the German known patent has a problem that the rotation operation of the rotary handle is required in addition to the insertion operation of the identification card.

On the other hand, "German Patent Application No. 3306863" discloses a device for starting a vehicle engine using an electronic key.

The electronic key can be displaced longitudinally between a plurality of operating positions which are axially displaced, in which case the electronic contact executes various functions by interaction with the transmit-receive unit in the respective operating position. In addition, the electronic keys are fixed in their respective operating positions by locks or manually pivotable brake levers.

However, the patent has a problem in that a new operating position is required for each successive work process. In addition, the device must maintain its final position by pressure until the engine is operated after the electronic key has been inserted to its final position to start the engine. Since each working procedure is assigned to one operating position of the electronic key, the device has to be designed with a correspondingly large scale.

On the other hand, "Korean Patent Application No. 10-2002-7002268" is known a technique for inserting the electronic key into the interior of the receiving portion.

This patent is a key insertion / removal operation by the operation of the hoisting magnet of the cam gear and rotator. In addition, this method allows the function to be selected in each step by the operation response according to the position of the micro switch.

Therefore, the patent uses components such as a hoisting magnet and a micro switch of a cam gear and a rotator connected to a motor in an operation of inserting / exporting an electronic key into a receiving portion.

Accordingly, the conventional patent has a problem in that the manufacturing process cost is increased due to the increase in the number of electrical parts, if the parts such as a motor is broken, the repair cost accordingly increases. In addition, there is a problem that the assembly between these parts is poor. And, there is a problem that the noise between parts due to the poor assembly.

2 and 3, the state before the electronic key 50 is inserted into the bracket 200 will be described.

The slider 300 is located at the front end of the bracket 200. In addition, the pair of rotator guides 310 positioned at both sides of the slider 300 are open to each other. That is, the fixing protrusions 312 provided at one end of the rotator guides 310 are open to each other. This state is achieved by the return force of the return spring 311 fitted to the rotary shaft 310a of the rotator guide 310.

Here, the other ends of the rotator guides 310 are supported by the first guide 241 of the guide member 240, as shown in FIG.

In addition, the elastic spring 320 connecting the rear end of the slider 300 and the rear end of the bracket 200 is in a relaxed state.

In addition, one end of the guide ring 220 installed at the rear end of the bracket 200 is in contact with the initial position ① of the guide path portion 340 provided at the rear end of the slider 300, as shown in FIG.

In this state, if the electronic key 50 is pushed into the insertion opening 121 of the open cover 120 in the direction of the arrow, the state as shown in FIG.

This state will be described in detail.

When the electronic key 50 is pushed into the insertion opening 121 of the open cover 120, the electronic key 50 pushes one side of the opening and closing door 110, and the opening and closing door 110 is rotated downward to insert the insertion opening 121. To open.

Subsequently, one surface of the electronic key 50 contacts the diaphragm 301 of the slider 300. When the electronic key 50 is continuously pushed in such a state, the elastic spring 320 is compressed.

Then, one end of the guide ring 220 waiting at the initial position (position I) of the guide path portion 340 is moved to the intermediate position (position II) along the first path as shown in FIG. At this time, one end of the guide ring 220 which is moved along the first path is formed so that the first path is stepped downward, so that it does not proceed from the intermediate position (position II) back to the initial position (position I), that is, in the reverse direction. can not do it.

As such, while one end of the guide ring 220 is positioned at an intermediate position (position II), the slider 300 is slidably moved in the direction in which the elastic spring 320 is compressed. In this case, the other end of each of the pair of rotator guides 310 may be positioned as the second guide 242 along the first guide 241 of the guide member 240. That is, the rotator guides 310 may be parallel to each other.

At this time, the fixing protrusions 312 formed at one end of the rotator guides 310 move along both sides of the electronic key 50 that is slid and inserted into the fixing grooves 51 formed at both sides of the electronic key 50. Can lose.

Therefore, the electronic key 50 is inserted through the insertion hole 121, one end of the guide ring 220 is positioned in the intermediate position (position II) of the guide path portion 340 to be inserted and positioned inside the slot device Can be.

At this time, the damper 250 provided at the front end of the slider 300 and the stopping rubber 230 provided at the front end of the bracket 200 are spaced apart from each other.

And, the antenna coil 410 located at the bottom of the electronic key 50 receives the authentication information stored in the electronic key 50, the controller 420 provided in the printed circuit board 400 To send).

In addition, the antenna coil 410 may charge a battery provided in the electronic key 50.

The controller 420 may turn on the LED lamps 432 when the received authentication information is the same as the preset authentication information. The light of the lit LED lamp 432 may be emitted to the outside through the exposure hole 122 of the open cover 120 through the illumination lens 431. Therefore, due to the emitted light, it is possible to visually know the authentication state and the charging state of the electronic key 50.
