Trunk switch module for vehicle

1. A trunk switch module for a vehicle, comprising:

a housing, of which a rear side is partially inserted into a trunk lid of the vehicle, having a mounting space at a front side of the housing;

a trunk switch disposed in the mounting space to selectively open the trunk lid according to an operation of a user;

a cover assembly attached to a front edge of the housing to close the opened front side of the housing, the cover assembly having a button sealing unit which corresponds to the trunk switch;

a protection film attached to a front surface of the cover assembly; and

an emblem mounted on the cover assembly at a front side of the protection film,

wherein the housing includes an air vent hole at one end of the housing for ventilating the mounting space, and

wherein, when the cover assembly is mounted on the housing to seal the mounting space, pressure generated in the mounting space is released through the air vent hole to prevent the trunk switch from not being actuated due to the pressure in the mounting space,

wherein the cover assembly includes:

a main body having a mounting hole at an upper portion of the main body to correspond to the trunk switch so that the button sealing unit is disposed in the mounting hole;

a flange unit integrally formed on an outer circumference of the main body; and

a vehicle body sealing unit integrally formed on a rear surface of the flange unit,

wherein the main body includes, below the mounting hole, an engagement protrusion integrally formed in the main body so that a lower part of the button sealing unit covers the outer circumference of the main body,

wherein the main body includes, on a rear surface thereof, a coupling groove corresponding to a coupling protrusion of the housing,

wherein the main body is coupled to the housing through ultrasonic fusion while the coupling protrusion is inserted into the coupling groove,

wherein a label tape is attached to the emblem so that the trunk switch is disposed on an upper front surface of the emblem, and

wherein the housing includes a mounting pad for fixing the housing in the trunk lid at the rear side of the housing.

2. The trunk switch module of claim 1 , wherein:

the button sealing unit and the vehicle body sealing unit are insert-injected into the main body and the flange unit, respectively.

3. The trunk switch module of claim 1 , wherein:

the button sealing unit and the vehicle body sealing unit are formed of thermoplastic poly urethane (TPU) materials.

4. The trunk switch module of claim 1 , wherein:

the front side of the main body has the same color as a body of the vehicle.

5. The trunk switch module of claim 4 , wherein:

the protection film is an anti-chipping film that protects a painted surface on the front surface of the main body.

6. The trunk switch module of claim 1 , wherein the trunk switch includes:

a tack switch mounted on the rear side of the housing; and

a push block disposed in the mounting space and moving, forward and backward to correspond to the tack switch, the push block to selectively contacting the tack switch and turning on or off the tack switch while selectively contacting the tack switch.

7. The trunk switch module of claim 6 , wherein:

the push block includes a contact protrusion contacting the tack switch at a rear side of the push block.
