Abstract
The present invention relates to a button-type car ignition system. The present invention includes: a housing the upper and lower portions of which are open; an upper plate coupled with an upper end of the housing; a moving button disposed inside the housing; a cover coupled with the lower portion of the housing; a printed circuit board disposed inside the housing; a key pad pressurized by the moving button; a light guide member that guides light generated by the light-emitting diode to the moving button; and an antenna coil that transmits and receives a wireless signal to and from an ignition key. According to the present invention, no additional components are required to install the antenna coil, and thus the number of components can be reduced, the number of assembly steps is reduced, and productivity is improved.
Claims9
A button-type car ignition system comprising:
- a housing having opened upper and lower portions;
- an upper plate coupled to an upper end of the housing and having a through-hole;
- a moving button arranged to reciprocate inside the housing;
- a cover coupled to the lower portion of the housing;
- a printed circuit board arranged inside the housing and having one or more light-emitting diodes;
- a key pad having an elastic protrusion portion pressed by the moving button;
- a light guide member for guiding light generated by the light-emitting diodes to the moving button;
- and
- an antenna coil installed on and wound onto the light guide member so as to transmit and receive wireless signals to and from an ignition key;
- wherein the light guide member comprises:
- a ring portion fitted between the moving button and the upper plate such that an upper end of the ring portion is exposed to the outside of the housing;
- and
- a light focusing portion configured for refracting light generated by the light-emitting diodes such that the light is focused on the ring portion.
A button-type car ignition system, comprising:
- a housing having opened upper and lower portions;
- an upper plate coupled to an upper end of the housing and having a through-hole;
- a moving button arranged to reciprocate inside the housing;
- a cover coupled to the lower portion of the housing;
- a printed circuit board arranged inside the housing and having one or more light-emitting diodes;
- a key pad having an elastic protrusion portion pressed by the moving button;
- a light guide member for guiding light generated by the light-emitting diodes to the moving button;
- and
- an antenna coil installed to the light guide member so as to transmit and receive wireless signals to and from an ignition key;
- wherein the housing is formed with a partition wall which guides the moving button and forms a separate space portion;
- and
- wherein the partition wall has a bending prevention portion which encloses one side of the elastic protrusion portion in order to prevent the elastic protrusion portion from being bent by the pressing member.
