FIG. 6 is a diagram illustrating components of a trunk switch assembly integrated with an emblem according to the exemplary embodiment of the present disclosure.

As illustrated in FIGS. 3 and 6, a trunk switch assembly integrated with an emblem according to an exemplary embodiment includes a body 10, and an emblem knob 20 that is coupled with an outer side of the body so as to have an emblem provided on an outer surface thereof, and is provided with a switch operating rib 70. The trunk switch assembly further includes a micro switch 40 that is provided both in a switch case 30 and the body 10, a pad 60 provided between the emblem knob 20 and the body 10, a return spring 7 that is provided on the body 10 to apply the pressing or restoration operating force of the emblem knob 20, a case 18 that is connected between the body 10 and the switch case 30 and has a hole provided therein, the micro switch 40 penetrating through the hole, and a link plate 80 that is provided in the case 18.

The emblem knob 20 has an emblem symbolizing an automaker provided on an outer surface thereof. The emblem knob 20 has a sealing groove 21 at its peripheral, for waterproof and preventing foreign substances from coming in from the outside. The sealing groove 21 is provided in a stepped form around the outer surface of the emblem knob 20.

A center of an inner side of the emblem knob 20 is provided with a switch operating rib 70 that enables the micro switch 40 to operate according to the motion of the emblem knob 20. The switch operating rib 70 extends vertically from the inner top surface of the emblem knob 20.

The bottom surface of the emblem knob 20 at its both ends are provided with guide members 25 that are inserted into guide holes 15 of the body 10. The guide members 25 vertically move within the guide holes 15, such that the guide members 25 may guide the entire emblem knob 20 so as to move vertically without shaking. The guide member 25 has a shape corresponding to that of the guide hole 15 of the body 10 and may preferably have a cylindrical shape so as to smoothly move in the vertical direction.

The outer circumference of the emblem knob 20 is coupled with a decoration 90. The decoration 90 serves to decorate an edge of the outer surface of the trunk switch assembly integrated with an emblem.

The sealing groove 21 provided on the emblem knob 20 is coupled with a waterproof ring 95 that is separately provided. The waterproof ring 95, which prevents moisture from coming in from the outside, serves to prevent moisture from permeating a clearance between the edge of the emblem knob 20 and the decoration 90.

The inner side of the emblem knob 20 is coupled with a pad 60. The pad 60 is made of a rubber material and serves to prevent moisture from permeating, together with the waterproof ring 95.

Referring to FIGS. 3, 5 and 6, the pad 60 is provided with two link portions 65. Each of the link portions 65 is inserted into a link mounting groove 11 that is provided on the body 10, such that the entire link portion 65 is provided in the body 10 and has one part coupled with the link plate 80. The link plate 80 is provided in the case 18 and mounted on the body 10. The link portions 65 are provided at both ends of the pad 60. Referring to FIG. 5, one of the link portions 65 includes a first link L1 having one end connected with the pad 60 and the other end on which a first hinge point H1 is formed, and a second link L2 having one end rotatably connected with the first link L1 through the first hinge point H1 and the other end connected with the link plate 80. The other link portion 65 includes a third link L3 having one end connected with the other part of the pad 60 and the other end on which a second hinge point H2 is formed, and, a fourth link L4 having one end rotatably connected with the third link L3 through the second hinge point H2 and the other end connected with the link plate 80.

Both parts of the link plate 80 are connected with the link portions 65, that is, the second link L2 and the fourth link L4 of the link portions 65, such that the part of the link plate 80 connected with the second link L2 and the other part of the link plate 80 connected with the fourth link L4 are integrally formed and the inside of the link plate 80 is formed with a hole through which the micro switch 40 penetrates so as to transfer the motion of the link portion 65 horizontally.

With reference to FIG. 3, the motions of the link portion 65 and the link plate 80 are described in more detail. When the outside of the emblem knob 20 is biasedly pressed to any one part, rather than the center, the first link L1 moves vertically by a vertical force that is biasedly transferred. Therefore, the first link L1 transfers force to the first hinge point H1 and the first hinge point H1 rotates by the force transferred from the first link L1. The second link L2 connected with the first hinge point H1 rotates together with the rotation of the first hinge point H1, such that the link plate 80 connected with the second link L2 moves with the horizontal force generated by the rotation of the second link L2 and the first hinge point H1. The fourth link L4 having one part connected with the link plate 80 also moves horizontally together with the motion of the link plate 80 to transfer force to the second hinge point L2 and the second hinge point H2 rotates by the force transferred from the fourth link L4. The third link L3 connected with the second hinge point H2 rotates together with the rotation of the second hinge point H2, and thus moves vertically. As such, even though the position biased to any one part of the emblem knob 20 is pressed, both parts of the emblem knob 20 move at the same stroke due to the motions of the link portion 65 provided by the pad 60 connected with the emblem knob 20 and the link plate 80 connected with the link portion 65 to move the switch operating rib 70, such that the micro switch 40 operates.

The body 10 is coupled to the pad 60 and serves to support the entire trunk switch assembly integrated with an emblem.

Referring to FIG. 4, in the body 10, a switch guide hole 19 that guides the movement of the switch operating rib 70 is provided at a position corresponding to the switch operating rib 70 that is coupled to the emblem knob 20. The switch guide hole 19 is formed as a hole extending outwardly from the body 10 and having a hollow inside. The switch operating rib 70 vertically moves in the switch guide hole 19 to operate the micro switch 40 that is provided in the body 10.

In one side of the body 10, the guide hole 15 that extends inwardly from the body 10 and has a hollow inside is provided at a position to which the guide member 25 of the emblem knob 20 is coupled. Therefore, the guide member 25 of the emblem knob 20 is inserted into the hollow inside of the guide hole 15.

The body 10 is provided with a drain hole 17. The drain hole 17 is a hole that discharges moisture introduced thereinto and is provided for the waterproof of the trunk, in combination with the waterproof ring 95 and the pad 60 made of a rubber material. Therefore, a double waterproof structure prevents the moisture introduced thereinto from permeating into the micro switch 40. The drain hole 17 is provided in plural to easily discharge moisture to the outside.

Referring to FIGS. 2 and 4, the body 10 is provided with the return spring 7 and thereby elastically supports the entire emblem knob 20 to improve the operating force. To this end, the body 10 is provided with a return spring supporting member 8. The middle of the return spring supporting member 8 is provided with a groove and the bottom surface of the return spring supporting member is closed, such that the return spring 7 inserted into the groove of the return spring supporting member 8 penetrates through the pad 60 to elastically support the emblem knob 20. Therefore, when the emblem knob 20 is pressed from the outside, the return spring 7 is pressed and when the force pressing the emblem knob 20 is removed, the emblem knob 20 returns to an original position again by an elastic restoring force of the return spring 7. The plurality of return springs 7 may be preferably provided at positions symmetrical with each other so that the emblem knob 20 is applied with the uniform elastic restoring force.

The inside of the body 10 is provided with the case 18 in which the link plate 80 is received and the inside of the case 18 is connected with the switch case 30 in which the micro switch 40 is received. Therefore, the case 18 and the link plate 80 are provided with micro switch through holes so that the micro switch 40 may operate by the switch operating rib 70.

Referring to FIG. 3, in the trunk case integrated with an emblem provided by the foregoing configuration, when the outside of the emblem knob 20 is pressed, the switch operating rib 70 provided on the emblem knob 20 moves vertically, and thus contacts the micro switch 40 provided in the switch case 30, such that the micro switch 40 operates. In this case, the emblem knob 20 is pressed and applied with the restoration force by the return spring 7 that supports the entire emblem knob 20. Even though an area close to the peripheral side of the emblem knob 20, not the position at which the switch operating rib 70 of the emblem knob 20 is provided, is pressed, the switch operating rib 70 enables the micro switch 40 to operate by the motions of the link portion 65 of the pad 60 and the link plate 80. Further, it is possible to prevent moisture from coming thereinto due to the pad 60 made of a rubber material and the waterproof ring 95 provided at the outer side of the emblem knob 20 along the circumference of the emblem knob 20. This configuration achieves the double waterproof due to the drain hole 17 provided on the body 10 to discharge moisture to the outside even when moisture is introduced.

As set forth above, it is possible to improve ability to open the trunk and convenience of the trunk and avoid the design restrictions by attaching the trunk open switch to the emblem, have the waterproof structure provided in the trunk, and improve the operability of the trunk by operating at the same stroke whichever part of the emblem is pressed.
