Description

FOB key for vehicle < RTI ID = 0.0 >

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a Paw key for a vehicle, and particularly to a side button type vehicle Paw key having a structure in which a button for remote operation is disposed on a case side.

In order to prevent vehicle theft in the early days of the automobile industry, the security device for vehicles started with door locks installed on the vehicle doors. Then, a turn key type anti-theft device in which the steering lock was interlocked with the ignition switch Device.

In addition, with the recent development of communication technology, smart key system of electronic authentication method which further enhances security convenience has been introduced and is being applied to actual vehicles. The smart key system has a mechanism for exchanging wirelessly encrypted information between the FOB key and the vehicle-side communication device and wirelessly controlling the desired operation.

To this end, the smart key system basically includes the Pawkey for remote control. The smart key has a portable size. According to the needs of the customer, the smart key has recently become smaller and thinner in size and thickness that can be carried in a wallet or a pocket.

Depending on the structure and the input method, the Pobu key can be divided into a mechanism type and a touch type. The mechanism type includes a mechanical switch that is switched to a physical force from the outside. The touch type includes a touch sensor capable of recognizing a desired operation command by a simple touch of a user.

In the touch type, since it does not require a large force for operation and does not use a component that occupies a large physical space such as a mechanical switch, it is advantageous in downsizing and thinning as compared with a mechanism type. However, the manufacturing cost is high, the circuit configuration is complicated, and even unintentional operation is recognized as a normal touch and a motion command is output.

For this reason, it is still in the field that machine types are preferred. However, in the case of the apparatus type, since the size and thickness of the apparatus are reduced in size and thickness, the internal physical space is reduced, which makes it difficult to mount the switch and the electric element, and there is a limitation in expanding the functionality.

Moreover, most of the conventional Paw keys have function operation buttons disposed on the front face of the case. Therefore, the minimum physical space in which the switch can operate within the case must be secured in the thickness direction of the case, and therefore, there is a limit to reduce the thickness thereof.

In addition, in order to provide products in various modes with different button operation feeling (pressing load, operating distance, etc.) according to the specifications, it was possible to change the internal structure of the case according to the specifications. Therefore, it is difficult to share the production line, so the competitiveness is low in terms of cost and mass production, and it is difficult to tune the operation feeling in the state of the finished product.
