Description

[Detailed description of the invention] The present invention relates to an automobile hood lock device.

In particular, the present invention relates to a hood lock device that can prevent unauthorized unlocking from outside the vehicle.

2. Description of the Related Art Conventionally, the hood of an automobile is provided with a locking device that can be unlocked from inside the vehicle via a control cable.

As shown in FIGS. 1 to 3, a conventional hood lock device includes a base plate or housing 1, a lock mechanism 2 provided therein, and a control cable 3 led from the lock mechanism 2 into the vehicle interior. It consists of

The housing 1 is bolted to the inside of the radiator core support 4 of the front body through holes 5.

The locking mechanism 2 includes a latch 6 and a locking plate 7.
It is composed of.

Here, the latch 6 engages with a striker 8 planted below the inner panel H of the hood, and is rotatably attached to the nozzle 1 by a pin 9.

Further, the locking plate 7 is used to maintain the meshing state of the latch 6 and the striker 8 as well as to release the meshing between them, and is similarly rotatably attached to the housing 1 by a pin 10. .

The latch 6 and the locking plate 7 are in such a relationship that when the latch 6 engages with the striker 8 as shown in FIG. The hood will be locked in this state.

Next, when the hood is unlocked, the protrusion 12 is removed from the lower jaw 11, and the striker 8 is released from the latch 6 due to the upward force applied to the hood in advance.

Note that a manually operated safety latch 13 is pivotally supported on the housing 1 in order to prevent the hood from being accidentally released.

Further, a spring 14 that maintains the locked and unlocked states of the latch 6 and the locking plate 7 is stretched between them, so that the latch 6 moves clockwise around the bin 9, and the locking plate T moves clockwise around the bin 9. They are each biased counterclockwise about 10.

On the other hand, the control cable 3 includes a flexible outer casing 15 and a core wire 16.

The outer casing 15 is made of a winding wire so as to have elasticity, and one end of the outer casing 15 is fixed to a stopper 17 provided near the driver's seat in the vehicle interior, while a tension knot is attached to the end of the core wire 16 on the interior side of the vehicle interior.・A steering wheel 18 is provided.

The other end of the outer casing 15 is fixed to the housing 1, and the other end of the core wire 16 is attached to a ball 19 fixed to the tip.
It is connected to the lower part of the locking plate 7 via.

In the conventional hood lock device configured as described above, in order to unlock the hood from the locked state as shown in FIG. 1, the driver's seat must pull the handle 18.

As a result, the core wire 16 is pulled to the left in the figure as shown in FIG. 3, the locking plate 7 is rotated clockwise, and the protrusion 12 is disengaged from the lower jaw 11 of the latch 6.

Then, the latch 6 also rotates clockwise due to the force of the spring 14 and the force of the striker 80 that tries to rise automatically, the striker 8 comes off the latch 6, and the inner panel H of the hood is temporarily stopped by the safety launch 13. Open until (.

At this time, if the handle 18 is released, the locking plate 7 returns to the position shown in FIG.

In addition, to lock the hood, the striker 8 is the lower jaw 1 of the latch.
1 and push it into the protrusion 12 of the locking plate.
This is done by pressing down firmly on the hood until it locks into place.

However, in such conventional devices, since the core wire 16 of the control cable is configured to unlock by pulling the locking plate 7, it is not necessary to pull the handle 18 to access the outside of the vehicle, that is, the bottom space of the front body or the radiator grill. There is a possibility that by pulling the control cable halfway through the outer casing 15, the outer casing 15 will be extended, and the core wire 16 will also be pulled, causing the hood to be unlocked.

Therefore, it is somewhat weak in reliably preventing theft of parts inside the engine room.

The present invention has been made in view of these conventional deficiencies, and has a structure in which the locking mechanism is unlocked by pressing the outer casing of the control cable, thereby preventing unauthorized attempts by pulling the control cable from an external force. To provide a hood lock device that can reliably prevent unlocking.

Hereinafter, the present invention will be explained in detail with reference to the embodiments shown in FIGS. 4 and 5.

In these figures, a hood lock device 3 according to the invention
0 is equipped with a base plate or housing 31 that is almost the same as the conventional one, a lock mechanism 32 provided inside this, and a control cable 33 that is wired from the lock mechanism 32 to the inside of the vehicle.

As in the conventional case, the housing 31 is fixed to the inner central upper part of the radiame core support with the front facing forward by a bolt (not shown) inserted into the hole 34.

The locking mechanism 32 also includes a latch 35 located on the left side when viewed from the front, and a locking plate 36 located on the right side.
It is composed of.

These latches and locking plates are located at bin 37, respectively.
It is rotatably attached to the housing 31 at an angle of .degree.

As in the prior art, the latch 35 has four parts between the upper jaw 40 and the lower jaw 41 so as to engage with the lower part of the striker 39 installed below the inner panel H of the hood.

On the other hand, the locking plate 36 holds the lower jaw 4 of the latch in order to maintain the latch 35 and the striker 39 in an engaged state.
A protrusion 42 that engages with the upper part of the body 1 is formed on the abdomen 1.

In order to keep the latch 35 and the locking plate 36 locked or unlatched, a spring 44 is stretched between them as in the prior art.

As a result, the latch 35 is biased counterclockwise about the bin 37 at the substantially central portion, and the locking plate 36 is biased clockwise about the bin 38 at the top.

However, instead of the spring 44, independent biasing springs may be provided for the latch and the locking plate, respectively.

1 Also, as in the conventional case, a manually operated V-shaped safety latch 45 is pivotally supported on the nozzle 31 by a pin 46, and its hook portion 47 is attached to the inner panel H of the hood.
In order to be able to constantly engage the outside of the drilled hole formed in the
8.

- On the other hand, the control cable 33 consists of an outer casing 49 and a core wire 50 inside the outer casing 49.

The eyeter casing 49 is made of a winding wire so as to be flexible and stretchable as in the conventional case, and one end of the eyeter casing 49 is fixed to a stopper 51 near the driver's seat.

Further, the outer casing 49 is configured to be slidably clamped to a substantial part of the vehicle body near the hood lock, for example, the radiame core support 4.

At the end of the core wire 50 on the inside side of the vehicle, a tension handle 52 that is engaged with a stopper 51 is provided.

The other end 53 of the outer casing 49 is fixed to the lower part of the locking plate 36 through the left side wall of the housing 31, and the other end of the core wire 50 is locked to the right side wall of the housing by a ball 54 provided at the tip. ing.

However, the ball 54 can also be fixed to the vehicle body.

As is clear from the structure of the above embodiment, FIG. 4 shows the hood in a locked state, with the latch 35 meshing with the lower part of the striker 39.

To unlock the hood from this state, the bundle 52 must be pulled on the inside of the vehicle, as in the conventional case.

As a result, since the end of the core wire 50 on the locking mechanism 32 side is fixed, the outer casing 49 is fixed as shown in FIG.
The end portion 53 of moves to the right in the figure.

Then, due to the pressing force at that time, the locking plate 36
and latch 35 counterclockwise,
The striker 39 will be removed from 5.

Since the striker 39 is given a force in advance so that the hood is always opened upwardly, it automatically rises as shown by the arrow.

At this point, the hood can be opened completely by further operating the safety latch 45.

If the bundle 52 is pushed back in the state shown in FIG. 5 and the core wire 50 is loosened, the locking plate 36 returns to the state shown in FIG. 4.

However, the lower jaw 41 remains oriented upwardly so that the latch 35 can again receive the striker 39.

At this point, if you push down the hood strongly, the striker 3 will be activated again.
9 and the latch 35 are engaged as shown in FIG.

As explained above, according to the present invention, the locking mechanism is unlocked by the pressing force of the outer casing of the control cable, so even if an attempt is made to illegally open the hood by pulling the middle of the control cable, the locking is more difficult. It will only become hard and you will not be able to unlock it.

Therefore, the theft of parts in the engine room can be completely and reliably prevented.

Furthermore, even if an attempt is made to unlock the lock by pushing the outer casing without pulling it, the control cable is flexible and will easily bend, making unauthorized operation completely impossible.

Therefore, the present invention provides a hood lock device that can reliably prevent theft.
