Abstract

PURPOSE: A theft prevention structure of a vehicle is provided to isolate the approach of a steeling tool by a simple structure. CONSTITUTION: The length of a first isolating plate(10) covers a latch operation lever and a safety lock rod. The width of the first isolating plate is the half of a cavity between a door inner panel(11) and a door outer panel(12). The one end of the first isolating plate is supported in brackets of the door inner panel through a pin(14). Both ends of the first isolating plate are supported in the door inner panel by winding a coil spring(15) in the pin. An inner hook(16) is formed in a free end. A second isolating plate(20) is formed with the same length and the same width as the first isolating plate. The second isolating plate is supported in brackets(21') of the door outer panel through a pin(22). Both ends of the second isolating plate are supported in the door outer panel by winding a coil spring(23) in the pin. An outer hook(24) is formed under a free end to hang in the inner hook. Thereby, the theft of a vehicle is prevented by preventing the locking release of a latch.

Description

Anti-theft structure of car {BURGLAR PROOF MEANS OF AUTOMOBILE}

The present invention relates to an anti-theft structure of an automobile, and more particularly, to an anti-theft structure for preventing the opening of the door by preventing the operation of the door latch operating lever and the safety lock rod.

As is well known, the door lock mechanism of a vehicle is normally unlocked by a key from the outside and the inside handle or the safety lock rod knob inside to release the lock. In addition, since the latch is connected to the safety lock rod knob therein, a third party can unlock the door by operating the latch operation lever or the safety lock rod.

The conventional unlocking method used by a third party uses a method of operating a door latch operation lever by pushing a stolen manipulation tool such as a screwdriver, a steel ruler or a wire between the door glass and the door outer panel.

In order to prevent the door latch unlocking, that is, theft prevention, a universal method of covering the plastic cover on the latch operation lever and the safety lock rod, or a dead locking system or an electronic method that cannot be unlocked without a key around the vehicle. Burger alarm systems and the like are known.

However, the method of covering the plastic cover on the latch operation lever and the swivel lock rod is expensive and requires a lot of assembly work. When the thickness of the plastic cover is thinned, it is difficult to achieve the desired purpose. In terms of period, investment cost and cost, it is unreasonable to apply to a small car, and the Burger alarm system is not only disadvantageous in terms of cost, but also has a problem that the desired purpose cannot be achieved when the wiring route is not perfect.

SUMMARY OF THE INVENTION An object of the present invention is to provide an anti-theft structure for an automobile which can block the access of the anti-theft operation tool to a latch operating lever and the like by a simple structure.

In order to achieve the above object, the present invention provides a first blocking plate that supports one end with a coil spring on the upper end of the latch operation lever, etc. of the door inner panel, and forms an inner hook with an open portion at the upper end thereof. ; One end is supported at the corresponding position of the first blocking plate of the door outer panel together with the coil spring, and a second blocking plate is formed at the free end of which the outer hook is formed at the lower part of the open part engaged with the inner hook.

1 is a side view of the vehicle, FIG. 2 is a cross-sectional view taken along the line AA of FIG. 1, FIG. 3 is a cross-sectional view taken along the line BB of FIG. 2, 10 is a first blocking plate, and the first blocking plate 10 is a latch in length. It is formed to a length that can cover the operation lever and the safety lock rod portion, and the width is formed to about half of the cavity between the door inner panel 11 and the door outer panel 12 so that one end of the door on the latch operation lever, etc. The coil spring 15 is wound around the pin 14 at the same time as the pin 14 is supported on the brackets 13 and 13 ′ formed on the inner panel 11, and both ends thereof are closed with the door inner panel 11. It is supported at one end, and formed at the free end the inner hook 16, the opening is located at the top.

20 is a second blocking plate, and the second blocking plate 20 is also formed to have the same length and width as the first blocking plate 10 so as to face the first blocking plate 10 of the door outer panel 12. One end in position is supported by the pins 22 on the brackets 21 and 21 'formed on the door outer panel 12, and at the same time, the coil spring 23 is wound around the pins 22 and both ends of the door outer It is supported on the panel 12 and one end, and formed on the free end to the outer hook 24, the opening is located at the bottom to be caught by the inner hook 16.

In addition, the pressing piece 17 is formed on the upper portion of the first blocking plate 10 so that its free end is located at the lower end of the door glass 18, and adjacent to the outer hook 24 of the second blocking plate 20. The position is to form the engaging piece 25.

Reference numeral 19 indicates the installation position of the latch, its operating lever and the safety lock rod.

In the present invention as described above, the first blocking plate 10 and the second blocking plate 20 are fastened by the elastic restoring force of the coil springs 15 and 23 by the outer hook 24 being caught by the inner hook 16. As shown in FIG. 2, when a third party inserts a stolen tool between the door glass 18 and the door outer panel 12, the tip contacts the second blocking plate 20 so that the second blocking plate ( Even if 20 is pressed, the outer hook 24 formed at the free end of the second blocking plate 20 is caught by the inner hook 24 formed at the free end of the first blocking plate 10, thereby blocking the second block. Since the plate 20 cannot be lowered, the anti-theft manipulation tool can no longer be inserted, thereby preventing access to the latch operation lever and the like, and thus preventing operation of the latch operation lever and the like (see FIG. 4).

When the operation tool is inserted as described above, when the operation tool is caught by the locking piece 25 formed at the position adjacent to the outer hook 24 of the second blocking plate 20, access becomes even more impossible.

When the door glass 18 is opened, the free end of the first blocking plate 10 is pressed by pressing the pressing piece 17 formed on the upper portion of the first blocking plate 10 while the door glass 18 is lowered. The outer hook 24 formed at the free end of the second blocking plate 20 by the inner hook 16 formed at the free end of the first blocking plate 10 while being lowered while overcoming the elasticity of the 15. When the door glass 18 is lowered by being released, there is no problem in opening the door glass 18. When the door glass 18 is raised to close the door glass 18, both blocking plates 10 and 20 are lifted. The inner hook 16 is caught by the outer hook 24 by the elastic restoring force of the coil springs 15 and 23 respectively installed at one end thereof, and is reduced to the state of FIG. 2.

As described above, the present invention provides a simple blocking plate which is interlocked by internal and external hooks on the upper parts of the door inner panel and the latch operation lever of the door outer panel, thereby preventing theft operation tools from accessing the latch operation lever. By preventing the unlocking of the latch by the structure, theft of the automobile can be prevented well.
