Description

[Detailed description of the invention] [Field of industrial application] This invention automatically locks the striker installed under the front-opening hood panel when it comes down by closing it, and this lock can be operated from the driver's seat. It can be released by operating the hood, and for safety purposes, it also has a mechanism that locks another safety striker similarly installed below the hood panel. This invention relates to a hood lock device that allows the hood to be opened.

(Problems to be solved by conventional technology and ideas) In this type of hood lock device, the safety lock mechanism locks the descending striker by being pressed against the spring force and swinging. It is formed by a lever that is operated to release the lock from the gap between the claw part and the tip of the hood. However, this lever was apparently located at the back of the hood tip, so I had to feel around to operate it.

In view of this, the object of the present invention is to provide a hood lock device of the type mentioned at the beginning, in which the operating lever for the safety lock is automatically advanced when the hood is opened.

(Means for Solving the Problem) In order to achieve this purpose, the present invention rotates the striker 2, which descends due to closure, to a lower locking position by being pressed against a spring force. The hood 5 includes a striker locking member 10 that locks the striker while rotating, a locking member 20 that locks the striker locking member 10 that has rotated to the locking position, and that can release this lock by operation from the driver's seat. The safety is equipped with a safety striker, and is formed by a claw portion 31a that swings and locks against a spring force when lowered and pressed, and a lever 32 for engaging and disengaging the hood with a finger from a gap 5a at the tip of the hood. The present invention is based on a food lock device comprising a taster lock member 30.

And the safety striker lock member 30
A pin 33 fixed to the engine compartment is movable back and forth, and is urged in the backward direction by a spring 34 to be pivotally supported on the base frame 1 on the engine room side, and furthermore, a tapered part 33b is formed at the rear end of the pin 33. At the same time, an actuating piece 1 is provided on the striker locking member 10 to abut the taper portion 33b from the side and drive the pin 33 forward against the spring force during the rotation operation process from the locking position to the locking and disengaging position.
7 was formed.

[Effect]

When the hood 5 is unlocked from the driver's seat, the striker locking member 10 rotates from the locking position to the locking position due to the spring force, and at this time, the actuating piece 17 rotates in conjunction with the locking member 10, thereby locking the pin 33. The tapered portion 33b is abutted from the side and driven forward against the spring force. As a result, the gap 5a at the tip of the hood
The safety lock lever 32 moves forward from the back to a position where it can be easily operated with a finger.

When the hood 5 is closed, the striker locking member 1
0 is rotated from the locking position to the locking position and locked, and at this time, the operating piece 17 releases the forward drive of the pin 33 and moves it backward by the spring force, positioning the lever 32 further into the gap 5a. .

[Example of idea]

1 and 2 show a food lock device according to an embodiment of the present invention.

In FIG. 1, reference numeral 1 denotes a base frame disposed in the engine room in the vehicle width direction. In this base frame, first, a striker locking member 10 is provided with a locking groove 11 around the periphery for locking the striker 2 provided below on the inner surface of the hood 5 that descends through the notch 1e. It is rotatably supported by. That is, the striker 2
When pushed downward, it slides into the locking groove 11 while rotating clockwise as seen in the figure, and rotates to the lower locking position. The base frame 1 is formed with a stopper bent portion 1d that restricts the counterclockwise rotation of the striker locking member 10 and defines the locking/disengaging position.

Furthermore, the base frame 1 is provided with a locking groove 21 that is slid into and locked when the locked piece 13 protruding from the striker locking member 10 rotates from the locking position to the locking position. 20 is
It is rotatably supported by a pin 22.

By tensioning the tension springs 15 on the spring locking levers 16 and 23 of the striker locking member 10 and the locking member 20, the striker locking member 10 is engaged in a counterclockwise direction as viewed in FIG. The locking member 20 is urged in the locking direction, which is clockwise as viewed in the figure. The base frame 1 includes a bent part 1a for a stopper that limits the clockwise rotation of the lock member 20 when the striker locking member 10 is engaged and disengaged, and a stopper bending part 1a that controls the angle at which the striker is pulled counterclockwise against a spring force. A bending portion 1b for a stopper is formed to allow the stopper to be bent. A traction lever 24 for pulling the lock member 20 in the unlocking direction is formed,
A cable 26 connected to its tip is connected through a guide groove 1c formed in the base frame 1 to a hood lock release knob provided inside the vehicle interior.

When another safety striker 9, which is similarly installed on the inner surface of the hood, descends and is pushed to the front side of the base frame 1, a tension spring 35 stretched between the base frame 1 and the base frame 1 is pressed.
A claw portion 31a that swings and locks against the spring force of
lever 31 and grill 5b at the tip of the hood.
A lever 32 extending forward for operating this lever 31 in the unlocking direction with a finger from the gap 5a between the
A safety lock member 30 is rotatably supported by a pin 33 fixed to the lower end of the lever 31. This pin can move back and forth orthogonally to the base frame 1, and is biased in the backward direction by a compression spring 34 loaded between it and a spring seat 33a formed at its rear end.

Further to the rear of the spring seat 33a at the rear end of the pin 33, a tapered portion 33b is formed toward the rear of the vehicle body. The front surface of the spring locking lever 16 of the striker locking member 10 is provided with a plate-shaped plate that is spaced upwardly from the taper portion 33b in the locking position and does not come into contact with it, but comes into contact with it when rotated to the locking position. An actuation piece 17 is formed. This actuating piece is the second
As shown in the figure, the contact surface 1 for the tapered portion 33b is inclined in accordance with the taper angle of the tapered portion 33b.
7a, and a parallel surface 17b to the spring locking lever 16 so that the tip of the tapered portion 33b rides on it.

The operation of the food lock device constructed in this way is as follows.

Usually, in the conventional striker 2, the locked piece 13 engages with the locking groove 21 at the position where it is locked in the locking groove 11, and is restrained by the tension spring 15. Further, the claw portion 31a of the safety lock member 30 locks the safety striker.

When the hood is opened, when the cable 26 is pulled by an operation from the driver's seat, the striker locking member 10 is unlocked by the rotation of the locking member 20, and rotates to the locking/disengaging position where it is restrained by the bending portion 1d by the spring 15. As a result, the actuating piece 17 rotates counterclockwise as seen in FIG. 1, and from the state shown in FIG. The pin 33 is moved forward against the pressure to bring it into the state shown in FIG. 2b. As a result, the lever 32 moves from the dotted line position to the solid line position, and its tip is placed in the gap 5 at the tip of the hood.
Displaced from a to a visible position. Therefore, the lever 32 can be easily operated upward.

When hood 5 is closed, main striker 2
comes into contact with the associated striker locking member 10, rotates downward, and is restrained by the locking member 20 at the locking position. At the same time, in this process, the actuating piece 17 rotates upward to release the pressure on the tapered portion 33b and retract the pin 33, and the claw portion 31a locks the safety striker 9.

[Effect of idea]

As described above, according to the present invention, the lever for unlocking the safety lock is normally located at the back where it cannot be seen as in the conventional case, but when the hood is opened, it is automatically displaced forward, thereby improving its operability.
