A switch body having a switch member connected by a cable to a drive unit for opening and closing a vehicle door, and an installation space for installing a printed circuit board; A knob member positioned to be movable inwardly or outwardly to allow a user to operate the switch member; It includes a connecting member that is integrally connected to the knob member and installed on the switch body, and is connected to the knob member and the switch body by a plurality of sealing portions. A vehicle door switch characterized in that the connecting member is made of the rigid material and the knob member is made of the elastic material, so that the knob member is installed so as to be movable inwardly or outwardly from the installation space.
In paragraph 1, A vehicle door switch characterized in that the connecting member and the knob member are integrally formed by an insert injection molding process.
In paragraph 1, the knob member is, A protrusion protruding to the outside of the above switch body; and It includes an operating projection that extends inwardly from the above-mentioned protrusion and protrudes toward the installation space, and is inserted into the installation space when a user presses the above-mentioned protrusion to operate the switch member. A vehicle door switch characterized by extending from the above-mentioned protrusion and the above-mentioned operating projection to form the above-mentioned sealing portion.
In paragraph 3, The above connecting member includes an extension insertion part that is inserted into a connecting groove formed by the gap between the installation space part and the switch body. A vehicle door switch characterized by the fact that the extension insertion part is provided with the sealing part connected to the switch body and the knob member.
In paragraph 4, the sealing part is, A first sealing part that connects the extension insertion part and the switch body and prevents moisture from entering through the gap between the connecting member and the switch body; and A vehicle door switch characterized by including a second sealing part that connects the extension insertion part and the knob member and prevents moisture from entering through the gap between the connecting member and the knob member.
In paragraph 5, A vehicle door switch characterized in that the first sealing portion includes a sealing groove portion that extends from the extension insertion portion and into which a rib protruding from the switch body is inserted and ultrasonically welded.
In paragraph 5, The second sealing portion includes a first bending portion that is extended and bent from the extension insertion portion, and A vehicle door switch characterized in that the first bend is formed integrally with the second bend of the knob member.
In any one of paragraphs 1 through 7, A vehicle door switch characterized by further including an operation feel improvement part that prevents the operation feel from being reduced as the operation protrusion, made of an elastic material, is deformed when it comes into contact with the switch member.
In paragraph 8, the above-mentioned operation feel improvement part is, A panel-shaped elastic member installed in the above-mentioned installation groove and movably supporting the above-mentioned knob member; and A vehicle door switch characterized by including an insertion groove formed in the installation groove so that the elastic member can be mounted opposite the knob member.
In any one of paragraphs 1 through 7, The above switch body further includes a terminal connection portion to which a terminal extending from the printed circuit board and the cable are connected. The above terminal connection part is provided with a flow prevention part that processes the cable to prevent damage to the connection part between the cable and the terminal, and The above-mentioned flow prevention unit is, A connection hole formed in the above terminal connection part; A fixed block made of an elastic material through which the cable inserted through the above connection hole passes; and A vehicle door switch characterized by including a storage groove provided in the terminal connection portion to fix the above-mentioned fixed block to the above-mentioned terminal connection portion.

Description

Vehicle Door Switch {DOOR SWITCH FOR VEHICLE} The present invention relates to a vehicle door switch installed in the trunk or end gate of a vehicle, which allows a user to open the door from the outside. Generally, a vehicle is equipped with doors for opening and closing the driver's seat, passenger seat, and rear seats. Each door is equipped with a window to ensure visibility of the outside of the vehicle. The windows of the vehicle doors open and close by raising or lowering through a predetermined opening and closing mechanism. As such, opening and closing devices for opening and closing vehicle windows include manual types that utilize the power of the occupant and automatic types that utilize electric power. Among these, the automatic type involves mounting a power window module on the door and operating a switch provided therein to raise and lower the window through a combination of the rotation of a motor provided inside the door and a link. A switch used to open and close vehicle windows or doors using electric power in this manner is a tact switch. An example of such a tact switch is disclosed in Korean Registered Patent No. 0747222. In particular, sports utility vehicles (SUVs) have recently been attracting public attention. Unlike sedans, vehicles of the SUV type feature a structure where the rear window, called the tailgate, and the rear door are combined and open together. A tact switch mechanism is applied to the locking device to open and close this tailgate. The tailgate can also be considered a type of trunk lid. The structure of a conventional tact switch device for a vehicle trunk consists of a tact switch that controls electrical connections mounted on a printed circuit board and installed in the body. An actuator capable of applying pressure to the tact switch installed in the body is installed, and the upper part of the actuator is covered with rubber. To secure the printed circuit board to the body, a back plate is attached to the body while pressing against the printed circuit board. Furthermore, the structure is formed by sealing the lower part of the back plate with epoxy resin to prevent moisture from entering the tact switch that controls electrical signals and the printed circuit board. However, conventional tact switch devices have a problem in that moisture can enter through the rubber on the upper part and the epoxy resin on the lower part of the tact switch, causing electrical damage to the tact switch or the printed circuit board. In addition, since the structure combining the tact switch and the printed circuit board cannot be standardized across different vehicle models, they must be manufactured separately for each model, leading to increased manufacturing costs. The background technology of the present invention is disclosed in Korean Registered Patent Publication No. 10-2245601 (published on April 29, 2021, title of invention: Tact switch device for a vehicle trunk).
