Description

[0001] The present invention relates to a door antenna switch for a vehicle,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door antenna switch for a vehicle and, more particularly, to an antenna switch for a vehicle door which prevents moisture from flowing between the head and the rubber portion when assembling the handle and the antenna switch, The size of the head portion attached to the antenna switch and the distance between the stopper portion and the rubber portion are reduced and a surface groove and a stepped shape are applied without using a separate watertight prevention rib to improve the adhesive force between the body portion and the rubber portion And more particularly to a door antenna switch for a vehicle that prevents moisture from being introduced into the vehicle door.

Recently, a door antenna switch for a vehicle, in which a door antenna is disposed inside a door of a vehicle and operates the door antenna, is installed so as to be exposed to the exterior of a door handle protruding from the outside of the vehicle. When the user holds the door handle, A smart key for a vehicle, in which a vehicle smart key and a door antenna are wirelessly transmitted and received to control opening and closing of a door and a trunk and starts an engine, has been developed. However, such a door antenna switch for a vehicle is buried to be exposed and installed Therefore, there is a problem that moisture is introduced from the outside through the gap formed between the door handle of the vehicle and the antenna switch, resulting in product failure.

In order to solve such a problem, Patent Document 10-1385139 entitled " Watertight structure of a door antenna switch for a vehicle ", which is registered by the applicant of the present application, discloses a waterproof structure of a door antenna switch comprising a plurality of watertight- A watertight structure formed by a double watertightness preventing rib formed between the rubber and the switch substrate portion and a wire fixing portion for preventing the flow of the wire drawn into the door antenna switch for the vehicle are formed on one side of the body portion, So that the waterproof effect can be maximized by preventing water from entering from the outside in a limited space of the door handle of the vehicle by sealing the inside of the door antenna switch for a vehicle.

However, in such a conventional door antenna switch for a vehicle, since the complicated structure of overlapping the rubber with each other and the cap and the rubber are separately injected and assembled separately, moisture is introduced into the space between the cap and the rubber and the icing phenomenon And a switching seesaw phenomenon and an overstroke phenomenon are generated due to the space generated due to the separation distance between the cap assembled in the rubber and the case inserted in the rubber, thereby causing problems such as switching malfunction.

As described above, according to the present invention, when the rubber portion of the door antenna switch for a vehicle is injected, the head portion and the body portion are simultaneously inserted into the rubber portion to form an integrated structure. It is possible to simplify the assembling process of the antenna switch to be attached to the door for a vehicle, thereby simplifying the manufacturing process and shortening the process time and manufacturing cost.

Further, due to the coupling structure in which the head part is inserted into the rubber part, the space between the head part and the rubber part, which is generated at the time of assembling between the head part and the rubber part, is eliminated to completely seal the inside of the door switch for the vehicle, It is effective to protect the switch substrate portion.

Further, according to the present invention, since the size of the head portion is reduced by the unified coupling structure of the head portion to be inserted into the rubber portion and the cap exposed to the outside of the vehicle covers the head portion, the door is exposed to the outside The area of contact between the door knob main body and the cap of the antenna switch is relatively reduced to minimize the freezing of the moisture by minimizing the inflow of water, thereby preventing the icing phenomenon and preventing malfunction of the switching.

In addition, it is possible to minimize the spacing between the stopper and the rubber portion of the switch board portion located inside the housing, which is composed of the head portion inserted into the rubber portion constituting the door antenna switch for the vehicle, and the housing portion to minimize the switching seesaw phenomenon and overstroke It is effective.

In addition, the present invention is characterized in that the body portion of the door antenna switch for a vehicle is inserted into the rubber portion of the automotive door antenna switch without providing a separate watertight prevention rib, thereby forming a combined structure in which the integrated rubber portion and the body portion are strengthened. A stepped portion and a surface groove are formed to reinforce the adhesive force between the rubber portion and the body portion, thereby forming a watertight structure preventing moisture from being introduced by the insert, thereby maximizing the waterproof effect.

Further, according to the present invention, a watertight structure is formed by bonding an epoxy molding liquid between a lower surface and a rim of a stopper portion to which a switch substrate is attached, It is an effective invention.
