Description

A device for locking a flap door of an engine

The present invention relates to a locking device of a flap door that is mounted to protect an engine of a motor vehicle, and more particularly to a flap door locking device of an automobile engine that can securely hold a locked state of a lock assembly.

In general, a rear wheel drive vehicle provided with a rear engine such as a bus is provided with a flap door for protecting the engine. The flap door is hinged to the rear of the body frame to be pivotable upward. It is installed.

In addition, the flap door is provided with a handle fixed by a latch and a striker on both sides of the lower flap, and prevents the latch and the striker from being accidentally released between the handles and theft of the engine parts. Locking assembly is installed to prevent foreign substances from entering.

Therefore, the flap door is opened by raising the handle while the locking assembly is released with the key.

In other words, the locking assembly of the prior art, which is capable of performing the above function, is shown in the schematic diagram of FIG. 1, and the locking assembly 110 is operable by inserting a key into the lower portion of the flap door 100. ) Is inserted and installed, the stopper 120 is installed on the rear of the locking assembly 110 to open and close the flap door while rotating at a predetermined angle.

In addition, the upper surface of the body frame 130 in which the flap door 100 is installed has a structure in which a locking bracket 140 is installed to be selectively caught on the stopper 120.

Of course, the body of the locking bracket 140 has a structure installed on the outside of the vehicle body compared to the body of the stopper 120.

Therefore, when the key is inserted into the locking assembly 110 and rotated, the stopper 120 installed on the rear side of the locking assembly rotates at a predetermined angle, and the locking state is maintained while being in surface contact with the rear surface of the locking bracket 140. Or the lock state is released while the surface contact is released.

However, since the locking assembly 110 is caught or released while the stopper 120 and the latching bracket 140 are in surface contact, the locking assembly 110 may be detached when the vehicle is vibrated or an impact is applied while passing through the uneven portion. There was a problem.

Accordingly, the present invention has been made in order to solve the problems described above, the flap door lock of the vehicle engine to prevent the deviation caused when the vehicle is vibrated by maintaining the locking state of the locking assembly firmly The object is to provide a device.

The present invention for achieving the above object, the locking assembly is inserted into the lower portion of the flap door to be operated by inserting a key, the rear of the locking assembly to open and close the flap door while rotating at a certain angle. In the flap door lock device having a stopper structure is provided so that the stopper, the locking member formed in the locking jaw is hinged to both sides via a rotation rod that can be rotated at a predetermined angle to the front end of the stopper, the flap The rear of the door is formed with a sliding groove through which the locking member can slide along the up and down direction, and the sliding groove is equipped with a guide bracket provided with an elastic spring for pressing the locking member downward. Locking mechanism to insert locking member in the lower frame of the door It has a structure consisting of a structure in which the locking bracket is formed with a groove.

Therefore, the locking member is held firmly while the locking member of the flap door is compressed to the locking bracket by the elastic spring, thereby preventing the accident of detachment of the locking device caused by impact while the vehicle vibrates or passes through the uneven part. Will be.

Hereinafter, an embodiment according to the present invention will be described in detail with reference to the accompanying drawings.

Figure 2 is a schematic diagram showing a state in which the flap door lock of the automobile engine according to the invention is mounted, Figure 3 is a schematic diagram showing a state in which the flap door lock of the automobile engine according to the invention is operated, these drawings As shown in, the locking assembly 110 is inserted into the lower portion of the flap door 100 to be operated by inserting a key, the flap door while rotating at a predetermined angle on the rear of the locking assembly 110. A flap door locking device having a stopper 120 configured to open and close, wherein the front end of the stopper 120 is locked to both sides by a rotation rod 10 that can rotate at a predetermined angle. A locking member 20 in which a 21 is formed is hinged, and a sliding groove 41 in which the locking member 20 is slidably moved along the up and down direction is provided at the rear of the flap door 100. At the same time, the sliding groove is equipped with a guide bracket 40 provided with an elastic spring 30 for pressing the locking member 20 downward, and a locking member (b) in the lower frame of the flap door 100. 20) is inserted into the lock bracket 51 is formed so that the locking groove 50 is formed so that the structure is made of a structure.

Here, the rotating rod 10 is hinged to the front end portion of the stopper 120 to be rotated at a predetermined angle, and in the state where the locking jaw 21 is formed at both sides at the top end of the rotating rod 10. The locking member 20 is formed in the lower portion has a structure in which the hinge is coupled.

In addition, the rear of the flap door 100 is mounted with a box-shaped guide bracket 40 via a fastening means such as a bolt, and the body of the guide bracket 40 along the up and down direction is a locking member 20. The sliding groove 41 is formed to penetrate through the sliding groove 41, and the locking member faces the downward direction between the upper surface of the sliding groove 41 and the locking jaw 21 of the locking member 20. It has a structure in which the elastic spring 30 is installed to be compressed.

Of course, the upper side of the sliding groove 41 has a structure in which the locking projection 41a is integrally formed so that the locking jaw 21 of the locking member can be caught.

On the other hand, the lower frame in which the flap door 100 is installed is equipped with a locking bracket 50 via a fastening means such as a bolt, the locking member 50 is moved to the locking member 50 in the vertical direction The locking groove 51 is inserted into and can be released while the structure is formed concave.

Hereinafter, described in detail with reference to the accompanying drawings illustrating the operation according to the present invention.

First, when the key is inserted into the key groove formed in the lock assembly 110 and rotated in one direction, the stopper 120 rotates simultaneously with the rotation of the key.

At this time, the stopper 120 rotates in the upward direction and pulls the rotation rod 10 upward.

In addition, since the rotation rod 10 is pulled upwards to raise the body of the locking member 20, the locking member 20 is locked to the locking bracket 50 bolted to the body frame 130 It is accommodated in the guide bracket 40 while being separated from the groove 51.

That is, when the body of the locking member 20 is inserted into the guide bracket 40, the locking of the locking member 20 is released.

Of course, when the locking state of the locking member 20 is released, the flap door 100 is opened.

On the other hand, when locking the flap door 100, when the key is inserted into the key groove formed in the lock assembly 110 and rotated in the opposite direction, the body of the locking member 20 is the elastic force of the elastic spring 30 While being lowered by being inserted into the locking groove 51 of the locking bracket, the locked state is maintained.

As described above, according to the flap door locking device of an automobile engine according to the present invention, the locking member of the flap door is firmly locked while being locked to the locking bracket by an elastic spring, so that the vehicle vibrates or is uneven. Passing through the site is the effect of preventing the accident of leaving the lock caused by the impact.
