Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a hood lock device.
[0002]
[Prior art]
For large bonnet vehicles such as those found in trucks and school buses mainly in the United States, engine maintenance and inspection work is performed by setting the hood to the front with the front end of the side rail as the tilt center axis and expanding the hood forward. I am getting it.
[0003]
At this time, in such a large bonnet vehicle, the assist spring force by the counter balance spring or the like is effective to reduce the physical labor of the hood opening / closing operation. Although the hood's own weight is supported by the assist spring force and held in an open state, the hood deployed forward closes carelessly from the viewpoint of ensuring safety when opening and closing the hood. It is necessary to support the hood with a hood lock device so that the hood lock device does not need to be supported. As this type of hood lock device, for example, the one described in Patent Literature 1 is already known.
[0004]
FIGS. 11 and 12 show an outline of a hood lock device described in Patent Document 1. As shown in FIGS. 11 and 12, a catch attached to a radiator support member b near the front end of a side rail a. A lock bar e, which is inclined so as to form a downward slope toward the front of the vehicle, is passed through the opening d of the member c, and the tip of the lock bar e is pivotally attached to the back surface of the front lower end of the hood f. In a neutral position where a counter balance spring (not shown) balances, a tooth g formed on a lower edge portion of the lock bar e in the middle in the longitudinal direction is engaged with the lower end of the opening d of the catch member c by the action of gravity.
[0005]
Also, the height at which the teeth g at the lower edge of the lock bar e do not engage with the lower end of the opening d of the catch member c is formed by hanging the outward flange h formed on the lock bar e over the notch i at the top of the opening d of the catch member c. It can also be held in position.
[0006]
[Patent Document 1]
US Pat. No. 5,791,428 [0007]
[Problems to be solved by the invention]
However, in the hood lock device of FIGS. 11 and 12 as described above, a large opening d for passing the lock bar e with the outward flange h is required, so that the catch member c is prevented from being enlarged. However, this causes a problem that the weight of the vehicle is increased, the cost is increased, and the layout is restricted due to the increase of the occupied space.
[0008]
Further, when the hood f is closed in a state where the engagement between the lower edge teeth g and the lower end of the opening d of the catch member c at the middle part in the longitudinal direction of the lock bar e is closed, the lower portion of the lock bar e Since the lock member e is inserted with a large play into the opening d of the catch member c, the lock bar e and the catch member c may interfere with each other due to vibration during traveling, and there is a possibility that abnormal noise may be generated. .
[0009]
Further, since the teeth g at the lower edge portion in the longitudinal middle portion of the lock bar e are formed in a saw blade shape, even if the hood f can be locked so as not to be inadvertently closed, the hood f is excessively moved forward. There is also a problem that it cannot be used also as an overtilt lock for preventing the unfolding from occurring.
[0010]
In view of such circumstances, an object of the present invention is to provide a hood lock device that is more compact than before, does not generate abnormal noise when unlocking, and can also be used as an overtilt lock.
[0011]
[Means for Solving the Problems]
The present invention is a hood lock device that supports a hood of a hood car deployed forward so as not to be inadvertently closed,
A hood hinge pivotally attached to a tilt center axis provided near the front end of the side rail and integrally attached to a front-side back surface of the hood;
The front end is pivotally connected to the hood hinge at a position displaced rearward by a required length from the pivot point of the hood hinge to the tilt center axis so that the front end is rotatably pivoted and descends rearward along the outer surface of the front end of the side rail. A hood stopper that is arranged in an inclined manner,
A guide slit extending from the middle portion in the longitudinal direction of the hood stopper toward the rear end and bent upward to form a hooking portion near the rear end;
The hood stopper is held in an inclined position by slidably and loosely fitting into the guide slit, and the hood hinge is tilted up when the hood is deployed forward, so that the hood stopper is pulled up. A guide pin protruding from the outer surface of the front end of the side rail so as to fit into the stop and prevent the hood stopper from returning downward;
The hood stopper, which is pivotally mounted between the side rail and the hood stopper so as to be rotatable about the guide pin and which is held in the lock position by the engagement of the guide pin from the release OFF position. A hood lock device comprising: a release lever that can be held at an unlocked position by being lifted by a rotation operation to a release ON position.
[0012]
According to the above means, the following effects can be obtained.
[0013]
When the hood is unfolded forward, the hood hinge is tilted integrally with the hood, and the hood hinge is tilted to raise the hood stopper, whereby the guide pin slides relatively to the rear end side of the guide slit. As a result, when the hood is fully engaged with the hood, the hood stopper is prevented from returning downward, and the hood is supported so as not to be accidentally closed. Will be held in the locked position.
[0014]
To release the lock, when the release lever is manually turned from the release OFF position to the release ON position, the hook portion is fitted into the guide pin, and the hood stopper held at the lock position is lifted, The hook of the hook is released from the guide pin, the hood stopper is held in the unlocked position, and the hook is prevented from being re-engaged with the guide pin. In such a state, the hood can be safely closed by turning around the hood and closing the hood with both hands.
[0015]
If a mechanism that locks and locks the guide slit on the guide pin is adopted, the overall structure becomes compact, and it is possible to avoid an increase in vehicle weight and cost. In addition, since the occupied space is small, restrictions on the layout are eased.
[0016]
Also, even when the unlocked hood is closed, the guide pins are loosely fitted through only a relatively small clearance that allows free sliding with respect to the guide slits. Therefore, there is no fear that particularly unpleasant noise is generated.
[0017]
Furthermore, since the guide pin does not come off the guide slit even when the hood is excessively expanded forward, it can also be used as an overtilt lock that prevents the hood from being excessively expanded forward. It is possible.
[0018]
In the hood lock device, a cam seating surface formed on a hood stopper side surface of a release lever such that a radial distance from a center of the guide pin gradually increases from the rear to the front, and
A rear end of the hood stopper is formed at a required position, engages with the hood stopper so as to ride on the cam seat surface in a state where the hood stopper is held at the lock position, and rotates the release lever from the release OFF position to the release ON position. And a cam receiving surface that is lifted by the cam seating surface in association with the moving operation. In such a case, the hand is held in a state in which the engaging portion is engaged with the guide pin. When the release lever is turned from the release-OFF position to the release-ON position, the cam seating surface of the release lever lifts the cam seating surface of the hood stopper, and the hooking of the hooking portion to the guide pin is released. The stopper is held in the unlock position.
[0019]
In the hood lock device, a rib extending upward around the guide pin and also serving as a reinforcement is provided on the side rail side surface of the release lever, and the rib is engaged with an outer peripheral portion of the guide pin. In addition, it is desirable to form a notch groove for restricting the rotation range of the release lever between the release ON position and the release OFF position. In this case, the release lever protrudes from the side rail side surface of the release lever. The rib that also serves as reinforcement engages with the notch groove formed on the outer periphery of the guide pin, and the movement of the release lever is restricted so that it only rotates between the release ON position and the release OFF position. There is no need to worry about malfunction due to no rotation above.
[0020]
Further, in the hood lock device, a reset projection is provided so as to protrude toward the release lever from a middle portion in the longitudinal direction of the hood stopper, and the reset projection is engaged with the reset projection under the release lever. And a reset protrusion receiving portion which is engageable with the reset protrusion receiving portion when the hood stopper moves rearward from the unlocked position when the hood is closed. It is effective that the release lever is pivotally returned from the release ON position to the release OFF position by pressing the one-side receiving portion. In this case, when the hood is closed, the hood stopper is unlocked. It moves backward from the position, but at this time, it protrudes from the lower part in the longitudinal direction of the hood stopper toward the release lever side. The setting protrusion engages with the reset protrusion receiving portion formed below the release lever to push the reset protrusion receiving portion, whereby the release lever moves from the release ON position to the release OFF position. The automatic return of rotation prevents the release lever from being forgotten to be returned, and when the hood is deployed forward at the next inspection, etc., the latch does not float with respect to the guide pin. As a result, the hood stopper is securely locked.
[0021]

The catch member c having a large opening d for passing the lock bar e with the h is unnecessary, and instead, the hood 5 is formed by a mechanism occupying a small space by the guide slit 10 and the small guide pin 12 formed in the hood stopper 8 itself. Is realized, the overall structure of the hood lock device becomes compact, and it is possible to avoid an increase in vehicle weight and a rise in cost. Will be.
[0039]
Even when the hood 5 is unlocked, the guide pin 12 is loosely fitted only through a relatively small clearance that allows the guide pin 12 to slide freely on the guide slit 10. Therefore, there is no danger that particularly unpleasant noise is generated by vibration during traveling.
[0040]
Further, since the guide pin 12 does not come off from the guide slit 10 even when the hood 5 is excessively expanded forward, an over-tilt lock that prevents the hood 5 from being excessively expanded forward is provided. It is also possible to use them together.
[0041]
On the other hand, the locking portion 11 can be released from the locking of the guide pin 12 simply by pinching and rotating the outward flange 20c of the release lever 20, so that the locked state can be easily released with one touch, and Even if the hand is released, the hood stopper 8 is securely held at the unlocked position without being affected by the variation of the effectiveness of the assist spring force acting on the hood 5, so that the hood 5 rotates forward. The hood 5 can be safely closed with both hands.

Further, the rib 20f serving also as a reinforcement protruding from the surface of the release lever 20 on the side rail 1 side is engaged with the notch groove 22 formed on the outer peripheral portion of the guide pin 12, so that the release lever 20 is released from the release ON position. By restricting the movement so as to rotate only between the OFF position, unnecessary rotation of the release lever 20 can be prevented, and malfunction can be prevented.
[0043]
Further, when the hood 5 is closed and the hood stopper 8 is moved backward from the unlocked position when the hood 5 is closed, the hood stopper 8 protrudes from the lower half in the longitudinal direction toward the release lever 20 side. The release piece 20 is released from the release ON position by engaging the projection 23 with a reset projection reception part 20g formed below the release lever 20 to push the reset projection reception part 20g. The rotation can be automatically returned to the OFF position, and it is possible to avoid forgetting to return the release lever 20. When the hood 5 is unfolded forward at the next inspection or the like, the engaging portion 11 Can be securely hooked without floating, and the reliability of the lock of the hood stopper 8 can be improved.
[0044]
