Description

Wireless electronic transmitter for vehicle engine starting system {REMOTE KEYLESS ENTRY FOR ENGINE STARTING SYSTEM FOR VEHICLE}

The present invention provides a wireless electronic transceiver for communicating with a vehicle externally and opening and closing the door of the vehicle electronically and enabling the engine to start when in the vehicle, wherein the structure of the housing is improved. It relates to a transceiver.

In general, in order to start a vehicle engine, the vehicle's key is inserted into a vehicle's key cylinder and rotated to a starting position. The vehicle could also be started with a key, preventing theft of the vehicle.

Accordingly, in recent years, a vehicle engine starting system using a wireless electronic transceiver has been popularized. The system uses the wireless electronic transmitter to communicate with the vehicle at a short distance from the outside of the vehicle to electronically unlock the door and prevents theft or damage of the vehicle at the command of the system when the driver leaves a certain distance from the vehicle. It automatically locks the door of the vehicle, and when the wireless electronic transmitter is located in the vehicle, it recognizes that there is a driver in the vehicle and enables the engine to be started by pressing the start button in the vehicle.

However, when power is not applied to the system due to system failure or discharge, or when the wireless electronic transmitter is discharged and the wireless electronic transceiver is not recognized by the vehicle, the emergency metal key is inserted into the key cylinder as described above. I had to start the engine. Accordingly, such a wireless electronic transmitter / receiver for a vehicle engine starting system accommodates an emergency metal key.

In the accompanying drawings, FIG. 7 shows an electronic key for a vehicle engine starting system according to the prior art.

Referring to Fig. 7, the electronic key 3 is shown in partial cross sectional view. The electronic key 3 comprises a housing 18 incorporating a switching button 19 which can initiate remote control functions.

The emergency key 20 is used for emergency opening of the vehicle by a closed cylinder installed in the vehicle when the control unit has completely failed. In the normal position the key shaft 21 is inserted into the recess 16 and locked by the locking device 22 which is operated by the button 23 and interacts with the key head 24. The head face 25 of the key head 24 ends in line with the head face 26 of the wireless electronic transceiver. When the emergency key 20 is separated from the electronic key 3, the button 23 is pressed and the emergency key 20 is drawn out.

However, when the emergency key 20 withdrawal structure such as the conventional electronic key 3 is configured, the housing 18 is not properly waterproofed, and thus it is inconvenient for the user because it requires attention in use.

In addition, the conventional electronic key 3 is divided into a top cover and a lower cover along a thin side surface of the housing 18 so that there is a gap between the two covers and is vulnerable to waterproofing. Since the battery cover of the receiving portion is forcibly separated from the housing 18, it is difficult for the user to replace the battery.

In addition, although the conventional electronic key 3 is attached with a label or a certification number for the wireless communication authentication and compliance with the law, there is a risk of hurting the appearance, such as being separated from the housing 18 with a long time use.
