Description

Car Key Cylinder Cover Device

The present invention relates to a key cylinder installed in a door outside handle of a vehicle and provided with a key insertion hole, and more particularly, to a key cylinder cover device of a vehicle to prevent foreign matter from accumulating at the inlet of the key insertion hole.

In general, as shown in Figure 1, the door (1) of the vehicle is provided with a door locking device for the purpose of preventing theft, the door locking device can be locked or unlocked in and out of the vehicle, Locking or unlocking is achieved by the operation of the key.

The door locking device is installed at the side end of the door and engages with the door striker installed in the body pillar to lock the door, the door inside handle and the door outside handle 2 for releasing the door latch locked to the door striker. And a rod connecting each device, and a safety knob for restraining locking or unlocking of the door, and a key cylinder into which the key is inserted into the door outside handle 2 so as to unlock or unlock the door from the outside. (3) is installed.

In addition to the doors, the key cylinders are also installed in the trunk lid and in the car for the operation of the trunk lid open and ignition switches.

As shown in FIG. 2, the key cylinder 3 includes a cylindrical body 4, a key insertion hole 5 formed inside the body 4, and a cover installed at an inlet of the key insertion hole 5. It consists of (6).

The cover 6 normally closes the key insertion hole 5 and opens the key insertion hole 5 only when the key 10 is inserted, and between the cover 6 and the key cylinder body 4, 7) is formed.

The operation of the door locking device configured as described above is as follows.

When the key 10 is inserted into the key insertion hole 5 of the key cylinder body 4 to open the door 1, the key 10 is inserted into the key insertion hole 4 while pushing the cover 6, Subsequently, when the key 10 is rotated, the locking or locking of the door 1 is released.

When the key 10 is removed from the key insertion hole 5, the key 10 is removed and the cover 6 is closed.

However, according to the key cylinder of the conventional door locking device, the front surface of the key cylinder 2 is exposed to the outside so that the step 7 between the cover 6 and the key cylinder body 4 provided at the inlet of the key insertion hole 5 is provided. ), Foreign matters such as dust, and the like, in particular, when the foreign matter strong adhesive force accumulated on the step (7) cover 6 is not normally opened and closed, even if you try to insert the key 10, the key 10 is the key insertion hole Since it is not inserted into (5), there was a problem that can not open and close the door (1).

The present invention has been devised to solve the problems described above, by preventing the accumulation of dust or foreign matter with strong adhesive force at the entrance of the key insertion hole to prevent the malfunction of the key is not inserted into the key insertion hole product It is an object of the present invention to provide a key cylinder cover device of a vehicle to improve the reliability of the vehicle.

The present invention for achieving the above object, in the key cylinder provided with a key insertion hole is installed in the door outside handle and the key is inserted to lock or unlock the door from the outside,

And a cover installed at the door outside handle to open and close the inlet of the key insertion hole, driving means for driving the cover, and switch means for driving the driving means in the proximity of the key.

Hereinafter, the present invention will be described in detail with reference to the drawings.

Figure 3 is an exploded perspective view of an embodiment according to the present invention, Figures 4 and 5 show the operating state of the embodiment in the present invention, Figure 4 shows a state in which the cover is closed the key insertion hole, Figure 5 The cover shows a state in which the key insertion hole is opened.

3 and 4, the key cylinder cover device of the present invention is fixed to the door outside handle, the base plate 20 is provided with a through-hole 21 for opening the key insertion hole 5 to the outside in the center And a disc-shaped link 30 rotatably installed on the base plate 20 and having a through hole 31 communicating with the through hole 21 of the base plate 20, and an end of the disc-shaped link 30. Fixed to the plurality of blades 40 to open and close the through holes 21 and 31 while being opened or retracted by the rotation of the disc-shaped link 30, and fixed to the upper end of the disc-shaped link 30, while the circular motion A solenoid 50 for rotating the plate-shaped link 30 and a spring bent in a circular shape and both ends thereof are fixed to the base plate 10 and the disc-shaped link 30 respectively to elastically support the disc-shaped link 30 in one direction. It consists of 60.

A predetermined position of the base plate 20 is provided with a guide protrusion 22 for guiding the fixation and rotation of the disc-shaped link 30 and the blade 40, and the guide protrusion 22 is inserted into the disc-shaped link 30. The guide hole 32 for guiding rotation is punctured.

A fixing hole 41 into which the guide protrusion 22 is fitted is drilled at a predetermined position of each blade 40, and a fixing protrusion 42 fitted into the coupling hole 33 of the link 30 is formed at an end of the blade 40. ) Is provided.

According to the present invention, the key is magnetized. When the key is located within a predetermined distance from the key insertion hole 5, the switch applies power to the solenoid 50 by attaching each lead piece by the magnetic force of the key, and the key is spaced a predetermined distance apart. If it is not affected by the magnetic force, each lead piece is a reed switch that cuts off the power supplied to the solenoid 50.

The entrance of the key insertion hole 5 is provided with a cover (not shown) that opens when the key is inserted as in the prior art.

Hereinafter, the operation of the embodiment according to the present invention will be described with reference to the accompanying drawings.

As shown in FIG. 4, the blade 40 according to the present invention maintains a state in which the respective through holes 21 and 31 are always closed. That is, the key insertion hole 5 is closed.

On the other hand, when the key is positioned at the front of the key insertion hole 5 from the outside to open the door, each lead piece of the reed switch is attached by the magnetic force of the key, and power is applied to the solenoid 50.

The rod 51 of the solenoid 50 is inserted into the solenoid 30 while moving in the A direction, and the circular link 30 overcomes the elastic force of the spring 60 by the linear movement of the rod 51. Rotate in the B direction. At this time, the disk-shaped link 30 is rotated while being guided by the guide projection 22 of the base plate 20 fitted in the guide slot 32.

The end of the blade 40 is also rotated by the rotation of the disc-shaped link 30, and at the same time, each blade 40 is rotated in the C direction separately from the disc-shaped link 30 about the guide protrusion 22. While being opened to open each of the through holes (21) (31). That is, the key insertion hole 5 is opened.

After the key is inserted into the opened key insertion hole 5, the door is locked or unlocked.

If the key is removed from the key insertion hole 5 after the door is locked or unlocked, and the magnetic force of the key does not affect the reed switch, each reed piece of the reed switch is dropped and the power supplied to the solenoid 50 is cut off.

The rod 51 is drawn out of the solenoid 50 while moving in the opposite direction by the spring (not shown) installed inside the solenoid 50, and at the same time, the spring elastically supports the disc-shaped link 30 in one direction. By 60, the disk-shaped link 30 is rotated in the direction opposite to B while being guided by the guide protrusion 22 in which the guide slot 32 is fitted.

At the same time, each blade 40 closes the through holes 21 and 31 while rotating in the opposite direction. That is, the key insertion hole 5 is closed.

Therefore, since each blade 40 closes the key insertion hole 5 and opens the key insertion hole 5 only when the key is inserted, the foreign substance having strong dust or adhesive force at the inlet of the key insertion hole 5 as in the prior art. This will not accumulate.

As described above, according to the key cylinder cover device of the present invention, foreign matter does not accumulate at the inlet of the key insertion hole, and thus malfunctions are not generated in which the key is not inserted into the key insertion hole, thereby improving the reliability of the product. .
