The folding key device for automobiles of the present invention for realizing the above object is formed with a key body consisting of a plate portion formed with a key row, and a seating portion on which one side of the key body can be accommodated, and the remaining portion is used for other purposes. The case, the rotating body rotatably coupled to the hinge portion formed in the corner of the case and the key body is eccentrically fixed, and inserted into the hinge portion from the side of the case to be rotated together with the key body A push button coupled to the rotating body, one end of which is fixed to the case, and the other end of which is fixed to the push button to elastically push the push button and at the same time provide an elastic force to unfold the key body; It is characterized by consisting of the folding holding means for blocking the rotation to maintain the key body folded state The following, when describing the embodiments of the invention with reference to the accompanying drawings as follows.

1 is a plan view and a front view showing a folding key device for a vehicle according to the present invention, Figure 2 is a front view showing a key body, Figure 3 is a view showing the folding holding means.

According to the present invention, a key body 10 having a rotating body 15 fixed thereto and a hinge portion 25 formed to rotatably install the rotating body 15 are inserted when the key body 10 is folded. A knob case 20 having a seating portion 23 formed therein and a hinge portion 25 inserted into a hinge portion 25 from the side of the knob case 20 and coupled to the rotating body 15 so as to rotate simultaneously with the key body 10. Both ends of the push button 30 and the push button 30 and the knob case 20 are fixed to the coil to push the push button 30 to the outside and to provide an elastic force to open the key body 10. It is composed of a spring (40).

The main parts of the present invention configured as described above will be described with reference to FIGS. 1 to 3.

The key body 10 is fixed to the plate portion 11 and the plate portion 11, the key portion is formed so as to lock or unlock the door, the trunk and the starting device of the vehicle, It consists of the rotating body 15 rotated in the hinge part 25 of the knob case 20. As shown in FIG.

Here, as shown in FIG. 2, the rotating body 15 has a hole 16 formed therein such that the push button 30 is inserted into and coupled to the center thereof, and the upper and lower surfaces of the rotating body 15 rotate the rotation range of the key body 10. To restrict the protrusion 17 is formed in the hinge portion 25 of the knob case 20.

Next, in the knob case 20, the upper case 21 and the lower case 22 are coupled to each other, as shown in FIG. 1, and a hinge portion 25 is positioned at one corner thereof, and the upper portion 21 of the knob case 20 is disposed on the hinge portion 25. A long groove-shaped seating portion 23 is formed to insert the key body 10 on the side.

Here, the hinge portion 25 is formed as a space in which the rotating body 15 of the key body 10 can be sufficiently rotated by a 180 ° radius, and the upper end of the coil spring 40 on the upper case 21 side. In addition to the insertion portion, a protrusion bar 27 for guiding the linear movement of the push button 30 is formed.

On the lower case 22 side, a hole 26 is formed to insert the push button 30 into the hinge portion 25, and the inside of the hole 26 limits the rotation of the push button 30. The engaging groove portion 28 is formed.

Two locking grooves 28 are formed at 180 ° in a portion protruding in an annular shape from the inside of the lower case 22.

The knob case 20 as described above may be provided with a remote door lock device or a remote start device in the remaining inner space except the hinge portion 25 and the seating portion 23.

Next, the push button 30 is formed in a cylindrical shape, a part of the coil spring 40 is inserted, the engaging projection 31 is inserted into the locking groove portion 28 of the lower case 22 on the outer peripheral surface. Is formed.

The locking protrusion 31 is coupled in the state inserted into both grooves 18 of the rotating body 15, as shown in Figure 2 when the user presses the push button 30, the locking of the lower case 22 Breaking out of the groove 28 is made to rotate with the key body 10 by the elastic force of the coil spring 40.

The locking groove portion 28 and the locking protrusion 31 of the folding holding means of the present invention are formed in the lower case 22 and the push button 30 in a 180 ° direction, respectively, as shown in FIG. In the direction in which the key body 10 is folded, the locking protrusions 31 are formed as mutually inclined surfaces 28a and 31a so that when the user provides a force to the key body 10, the locking protrusion 31 is easily separated from the locking groove 28. .

The coil spring 40 is inserted into the push button 30 as shown in FIG. 1 so that one end is fixed, and the other end is fixed to the upper case 21 to hold the push button 30. While providing an elastic force to push outwards, when the push button 30 is pressed, the elastic key is provided to expand the folded key body 10.

Referring to Figures 1 and 4 to 6 the operation of the folding device for a vehicle according to the present invention configured as described above are as follows.

As shown in FIG. 4, when the user presses the push button 30 protruding from the knob case 20, the key body 10 is extended while being rotated 180 ° by the elastic force of the coil spring 40.

That is, when the push button 30 is pressed, the locking protrusion 31 is separated from the locking groove 28, and at this time, the key body 10 and the push button 30 are rotated by the elastic force of the coil spring 40. It will be unfolded as it rotates.

As shown in FIG. 5, when the key body 10 is unfolded as shown in FIG. 5, the locking protrusion 31 is rotated by 180 ° so that the key body 10 is inserted into the locking groove 28 again to unfold the key body 10. The state is maintained.

After inserting and using the door lock device or the starting key set of the vehicle as described above, in order to fold the key body 10, the key body 10 may be folded by sliding in the direction of the seating part 23 of the knob case 20.

That is, as shown in FIG. 5, since the locking groove 28 and the locking protrusion 31 are formed as the inclined surfaces 28a and 31a in the key body folding direction, pressing only when a predetermined force or more is applied to the key body 10. The locking protrusion 31 of the button 30 rotates while being separated from the locking groove 28, and when the key body 10 is completely inserted into the seating part 23 of the knob case 20, the locking protrusion 31 is rotated. By being rotated 180 degrees, the key body 10 is maintained in a folded state by being coupled to the locking groove 28 again.

At this time, the coil spring 40 has an elastic force to expand the key body 10 by folding the key body 10.

Therefore, the folding key device for a vehicle of the present invention constructed and operated as described above is folded in the case when the user rotates the key body, and when the button is pressed, the key body is easily unfolded. It is easy to carry and store, which provides an advantage of improving user convenience. In addition, when various devices related to driving of a vehicle, such as a remote starter, are installed in the remaining parts except the seating part and the hinge part of the case, the device is inherently unique. By carrying out a function and storing a key at the same time, the user's convenience can be further increased.
