3 to 5 show an embodiment of the anti-theft device of the vehicle door outside handle according to the present invention, the outer side of the housing 31 which is fixed to the door outer panel 30 of the vehicle as shown therein Handle 32 is provided on the side, the lower portion of the handle 32 is provided with a concave inlet portion 33 for the user's hand, and the inner side of the housing 31 from both sides of the handle 32 A plurality of support brackets 36 and 37 for supporting two protruding hinge arms 34 and 35 are protruded, and the hinge arms 34 and 35 and support brackets 36 and 37 are supported. Both ends of the hinge shaft 38 penetrating both in the horizontal direction are fixed to the hinge arms 34 and 35 on both sides, and the hinge arms 34 and 35 are provided on both sides of the housing 31. An entrance and exit hole 40 and 41 are formed and a torsion fits on the hinge shaft 38. One end of both ends of the pring 42 is hung on the hinge arms 34 and 35, and the other end thereof is hung on the support brackets 36 and 37 so that the handle 32 is connected to the housing 31. On the hinge shaft 38, in the automobile door outside handle, which is adapted to give elasticity in the overlapping direction, and in which the key cylinder 44 interlocked with the handle 32 is located at the rear of the housing 31. A drive gear 50 engaged with the input gear 61 of the motion expansion mechanism 60 is installed, and a driven gear 51 that is engaged with the output gear 62 of the motion expansion mechanism 60 is installed at both ends thereof. The feed screw 54 having the right screw portion 52 and the left screw portion 53 formed thereon is provided by the supporter bearings 55 and 56, while at least the rear portion of each of the access holes 40 and 41 is provided. Two shielding plates 70 and 71 having a covering size are provided on the inner rear side of the housing 31 by a linear guide mechanism 80. Installed and connected to both of the right side screw 52 and the left side screw 53 of the transfer screw 54 is connected to the transfer screw 58, 59 of both sides.

The motion expanding mechanism 60 is rotated in engagement with the input gear 61 and coaxial with the first accelerator gear 64 and the first accelerator gear 64 having a pitch circle diameter smaller than that of the input gear 61. And a second acceleration gear 66 having a pitch diameter larger than that of the output gear 62 while being rotated at the same time as the first accelerator gear 64 and being rotated together with the output gear 62.

The linear guide mechanism 80 is a pin bolt 84a with spacers 82a, 82b, 82c, and 82d floating the shielding plates 70 and 71 from the housing 31. (84b) (84c) and (84d) are screwed into the respective screw holes (86a) (86b) (86c) (86d) formed in a row in the housing (31), and the shield plates (70) (71). The sliding holes 88a and 88b, which are slid to the pin bolts 84a, 84b, 84c and 84d, are formed in the horizontal direction, respectively, so that both sides 70a of the shielding plates 70 and 71 are formed. (70b) (71a) (71b) are the head (84e) (84f) (84g) of the spacer (82a) (82b) (82c) (82d) and the pin bolts (84a) (84b) (84c) (84d). (84h) is configured to slide in sliding contact.

In addition, the transfer nuts 58 and 59 are screwed into the engaging holes 70f and 71f formed in the shielding plates 70 and 71 by protruding the projections 58a and 59a horizontally from the bottom thereof. It is configured to be coupled so that the shield plate 70, 71 is also configured to move at the same time when the transfer nuts 58, 59 are moved.

With reference to the accompanying drawings, the operation and effect according to the embodiment of the present invention as described above will be described in detail.

As shown in FIGS. 3 to 5, when the handle 32 of the vehicle is pulled while the door lock is engaged, the handle 32 is slightly rotated due to the play and installed on both rear sides of the handle 32. The hinge arms 34 and 35 are also rotated together with the handle 32 so that the hinge shafts 38 installed on the hinge arms 34 and 35 are rotated, and at the same time, the hinge arms 34 and 35 are installed on the hinge shafts 38. The drive gear 50 is rotated to transmit power to the input gear 61 of the motion expansion mechanism 60, and the motion expansion mechanism 60 enlarges the movement therein and then transfers the screw through the output gear 62. The enlarged movement is transmitted to the driven gear 51 provided on the 54.

If described in more detail the action of the motion expansion mechanism 60 to exercise expansion as described above as follows. The power transmitted to the input gear 61 of the motion expansion mechanism 60 has a pitch circle diameter of the first acceleration gear 64 meshed with the input gear 61 smaller than the pitch circle diameter of the input gear 61. The first acceleration gear 64 is accelerated as much as the acceleration ratio. As the first acceleration gear 64 is rotated, the rotational force is transmitted to the second acceleration gear 66, and the power is transmitted to the output gear 62, and the output gear 62 is also lower than the second acceleration gear 66. Because of the small pitch circle diameter, the final acceleration is achieved.

That is, the greater the number of revolutions, the longer the moving distance is, so that the motion is expanded.

At this time, the feed screw 54 is rotated by the rotation of the driven gear 51 to send the left and right transfer nuts 58, 59 in a direction away from each other, shielding is connected to the transfer nuts 58, 59 The plates 70 and 71 move together with the transfer nuts 58 and 59 on both sides to move away from each other.

In this case, the shielding plates 70 and 71 seal the entrance and exit holes 40 and 41 formed on both sides of the housing 31 while performing linear motion by the linear guide action of the linear guide mechanism 80.

And the operation of the linear guide mechanism 80 for the linear guide action in more detail as follows. The shielding plate 70 (71) by guidance of the sliding holes 88a (88b) which are in sliding contact with the pin bolts 84a (84b) (84d) (84d) which are provided in a row at the rear part of the housing (31). ) Is restrained to move upward and downward, and the screw head 84e of the spacers 82a, 82b, 82c, 82d and the pin bolts 84a, 84b, 84c, 84d. Since the shielding plates 70a, 70b, 71a, 71b of the shield plates 70, 71 in sliding contact with the 84f, 84g, 84h are restrained to move back and forth, the shielding plate (70) (71) is to make a linear motion.

On the other hand, when the handle 32 was pulled, by the elastic return action of the torsion spring 42, the handle 32 is rotated in a direction opposite to the beginning to repeat the previous operation only in the opposite direction. That is, the entrance plate 40 and 41 are opened by linear movement in the direction in which the shield plates 70 and 71 are closer to each other.

In the present invention as described above, even if someone tries to insert a thin steel wire through the entrance hole by pulling the handle installed on the outside of the door while the door lock is closed, the shielding plate is to automatically cover the entrance hole There is no fear of stolen valuables or vehicles left in the car, and even if you move the handle a little by the movement enlargement mechanism, the shield moves largely to cover the entrance and exit, so that the operation is sure.
