Abstract
The present invention relates to a vehicle card key in which a manufacturing defect rate of the vehicle card key may be reduced when the vehicle card key is manufactured, and a method of manufacturing the same. A PCB substrate which has a first key holder receiving groove and a first battery cover; a case which has a second key holder accommodation groove and a second battery cover accommodation groove; a key holder which accommodates the mechanical key; a battery terminal which includes a first terminal and a second terminal; and a battery cover which allows one surface of the battery to be in contact with the first terminal and the other surface of the battery to be in contact with the second terminal.
Claims11
A vehicle card key in which a mechanical key and a battery are accommodated, the vehicle card key comprising:
- a printed circuit board (PCB) substrate which has a first key holder accommodation groove formed in one direction of the PCB substrate, a first battery cover accommodation groove formed in an other direction of the PCB substrate, and one surface on which circuit elements for wireless transmission and reception with a vehicle are mounted, wherein the mechanical key is assembled in the first key holder accommodation groove and the battery is assembled in the first battery cover accommodation groove;
- a case which has a second key holder accommodation groove formed at a position corresponding to the first key holder accommodation groove and a second battery cover accommodation groove formed at a position corresponding to the first battery cover accommodation groove and molds the one surface of the PCB substrate on which the circuit elements are mounted;
- a key holder which accommodates the mechanical key and which is fixed to the first key holder accommodation groove;
- a battery terminal which includes a first terminal fixed to the one surface of the PCB substrate and a second terminal spaced apart from the first terminal and fixed to an other surface of the PCB substrate and fixed to the first battery cover accommodation groove;
- and
- a battery cover in which a battery is accommodated and which is inserted between the first terminal and the second terminal and allows one surface of the battery to be in contact with the first terminal and an other surface of the battery to be in contact with the second terminal.
A method of manufacturing a vehicle card key, the method comprising:
- providing a printed circuit board (PCB) substrate which has one surface on which circuit elements for wireless transmission and reception with a vehicle are mounted and an other surface on which the circuit elements are not mounted and has a first key holder accommodation groove formed in one direction of the PCB substrate and a first battery cover accommodation groove formed in an other direction of the PCB substrate;
- fixing the other surface of the PCB substrate on which the circuit elements are not mounted to a lower mold;
- disposing an upper mold on the one surface of the PCB substrate on which the circuit elements are mounted;
- defining a preset space on the one surface of the PCB substrate on which the circuit elements are mounted and lowering the upper mold;
- injecting a molding material into the preset space and forming a case;
- curing and taking out the case;
- and
- fixing a key holder to the first key holder accommodation groove and fixing a battery terminal to the first battery cover accommodation groove.
The method of 10, wherein the battery cover includes cover supports which are in contact with both inner surfaces of the first battery cover accommodation groove and cover fixing protrusions which are formed at positions corresponding to the cover fixing holes and inserted into the cover fixing holes.
