Description

[Detailed Description of the Invention] This invention relates to a modification of a locking device for a vehicle bonnet.

Generally, in vehicle bonnets, when closing the bonnet, a striker provided on the bonnet bottom is locked by a fork lever, which is a locking member pivoted to a base plate provided on the vehicle body side, to keep the bonnet closed. When the bonnet is opened, the release wire is operated to unlock the claw lever, which also has a locking function for locking the fork lever in the locked position, to release the fork lever from locking the striker, and to open the bonnet. A locking device has already been put into practical use in which the striker is relocked by a safety lever in a slightly opened state, and the striker is released from the lock by manual operation of the safety lever to open the bonnet.

By the way, regarding the locking of the striker with the fork lever when closing the bonnet, in order to prevent errors during manufacturing and assembly and to ensure smooth operation when locking and releasing the lock,
A gap is provided between the locking part of the fork lever and the striker, but this gap causes the bonnet to rattle due to running vibrations, causing noise.

A similar problem also exists in hook-type bonnet locking devices.

For this purpose, there was a method in which the striker, which was locked by the locking member, was pressed against the locking part of the locking member using a separate lever.
Requires levers, pivot pins, biasing springs, etc., and requires manufacturing and
Assembly was not only troublesome but also expensive.

This idea was made in order to solve the above-mentioned conventional problems. Focusing on the safety lever provided in the locking device, the safety lever was given a striker pressing function and a separate lever was provided. This design was designed to prevent the bonnet from rattling.

Hereinafter, embodiments of this invention will be described in detail with reference to the accompanying drawings.

As shown in the figure, a base plate 3 fixed to the vehicle body 1 with flanges 2, 2 has a hinged bonnet 4.
A locking member is formed on the back surface of the base plate 3, which has a U-shaped engagement portion 7a corresponding to the fitting groove 6. A fork lever 7 is pivotally connected with a pin 8, and
A claw lever 9 as a release lever having a protrusion 9a that can be engaged with the recess 7b of the fork lever 7 is pivotally attached with a pin 10, and a coil spring 11 is stretched between the claw lever 9 and the fork lever 7. Then, the claw lever 9 is relatively biased in the locking direction (counterclockwise around the hour hand in the figure) and the fork lever 7 is relatively biased in the locking direction (counterclockwise around the hour hand in the figure).

Note that the coil spring 11 may be a separate spring provided for each lever 7.9.

When the bonnet 4 is opened, the fork lever 7 is
The engaging portion 7a swings to the non-latching position facing the striker fitting side of the fitting groove 6 and is positioned, and when the bonnet 4 is closed, the striker 5 guided by the fitting groove 6 is placed in the retaining portion 7a. When engaged, it swings counterclockwise and is positioned at a locking position where the striker 5 is locked.

At the locking position of the fork lever 7, the protrusion 9a of the claw lever 9 engages with the recess 7b of the fork lever 7, thereby locking the fork lever 7 in the locking position.

The claw lever 9 is connected to a release wire 12 that is manually operated from the passenger compartment side, and when the release wire 12 is operated to swing the claw lever 9 in the unlocking direction (around the hour hand in the figure), the claw lever 9 is released by the protrusion 9a. The lock of the fork lever 7 is released, and the fork lever 7 is moved by the coil spring 11.
By swinging around the hour hand, the striker 5 is unlocked.

On the other hand, the above-mentioned fitting groove 6 is provided on the surface of the base plate 3 in the figure.
Safety lever 1 having a hook portion 13a corresponding to
3 is pivotally connected with a pin 14, and the safety lever 1
3 is biased by a coil spring 15 in the direction of locking the striker (around the hour hand in the figure).

The safety lever 13 re-locks the striker 5, which has been released from the locking by the fork lever 7, at the upper position using the hook portion 13a, and operates the hand-operated portion 13b to prevent the gap between the bonnet 4 and the vehicle body 1. When the striker 5 is swung in the unlocking direction (counterclockwise in the figure), the hook portion 13a unlocks the striker 5, allowing the bonnet 4 to be opened.

The safety lever 13 is integrally formed with a convex pressing portion 13C that presses the striker 5, which is locked by the locking portion 7a of the fork lever 7, against the locking portion 7a of the fork lever 7.

If the locking device is configured as described above, when the bonnet 4 is currently closed, the striker 5 will be locked by the fork lever 7 that is swung in the locking direction, and the fork lever 7 will be locked.
is locked by a lock lever 9 that swings in the locking direction.

In this state, the safety lever 13 is urged in the locking direction by the coil spring 15, and the pressing portion 13C presses the striker 5 against the locking portion 7a of the fork lever 7, so that the locking portion 7a and the striker 5 are The gap between them is zero, and the bonnet 4 will not rattle due to running vibrations, so no noise will be generated.

Next, when the release wire 12 is manually operated from the passenger compartment side, the claw lever 9 swings in the unlocking direction to unlock the fork lever 7, and the coil spring 11 swings the fork lever 7 in the unlocking direction. The striker 5 is unlocked.

The bonnet 4 is swung in the opening direction by a spring mechanism (not shown), but the striker 5 is rotated by the safety lever 13.
It is locked by the hook part 13a, and the swinging stops in a slightly opened state.

Then, when the safety lever 13 is swung in the unlocking direction by inserting a finger into the gap in the bonnet 4 and manually operating the manual operation part 13b, the hook part 13a is moved to the striker 5.
The bonnet 4 can now be opened.

Note that the present invention can also be applied to a hook type bonnet locking device that has a locking member and a release lever at both ends, and whose intermediate portion is pivotally connected to a base plate.

As is clear from the above explanation, this invention has a pressing part formed on the safety lever of the locking device to press the striker against the retaining part of the locking member, so when the bonnet is closed, the pressing part Due to the pressure, no gap is created between the engaging portion of the locking member and the striker, the bonnet is no longer rattled, and noise due to running vibrations is no longer generated.

Furthermore, since it is only necessary to form a pressing portion on the safety lever, there is no need to provide separate levers, pins, springs, etc. as in the past, making manufacturing and assembly simple and cost-effective.
