Abstract

PURPOSE:To attain the certainty of the engaging operation of a secondary latch and a catcher. CONSTITUTION:A secondary latch 8 is mounted rotatably on a lock mechanism 7 engaged with and disengaged from a striker 6 on the engine hood 1 side while a catcher 12 engaged with and disengaged from the secondary latch 8 is installed rotatably to the rear-section side port edge of the lock-mechanism admission port 5 of a hood inner 2. The locking of the catcher 12 is released and operated by an operating stay 18 held on the rear of a grill section 3.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hood lock device for an automobile, and more particularly to an automobile having a grill-integrated engine hood in which a grill is integrally provided at a front end of the engine hood.

[0002]

2. Description of the Related Art Among the hood lock devices for automobiles equipped with an engine hood integrated with a grill, for example, on page D-32 of the introduction of the FGY32 type car of the new type car decoding document issued by Nissan Motor Co., August 1991. As shown, a manual lever mechanism for actuating a secondary latch pivotally supported by the lock mechanism is provided on the vehicle body side member provided with a lock mechanism for engaging and disengaging the striker on the engine hood side. It is known that the operation of the manual lever mechanism releases the engagement between the secondary latch and the catcher on the engine hood side.

[0003]

It is undeniable that when the engine hood is opened, the manual lever mechanism mounted on the front surface of the vehicle body side member is exposed and the appearance is deteriorated.

Further, since the shaft support portion of the secondary latch is exposed to the air that has passed through the grill portion, dust or the like may adhere and stick, so that expensive materials such as stainless steel must be used.

Therefore, the present invention can eliminate the manual lever mechanism and have a simple structure, which can greatly contribute to cost reduction, and can improve the appearance when the engine hood is opened, and further, the secondary latch and the catcher. It is intended to provide a hood lock device capable of performing a reliable engagement operation with.

[0006]

A secondary latch is rotatably provided on a lock mechanism that is disposed on a vehicle body side member and engages and disengages with a striker fixed to a hood inner of an engine hood, while a lock mechanism of the hood inner is rotatably provided. A catcher that engages with and disengages from the secondary latch is rotatably attached to an edge portion on the back side of the entrance, and the end portion of the operation stay held on the back surface of the grill portion at the front end of the engine hood is connected to the catcher. .

[0007]

[Function] When the engine hood is opened, when the lock mechanism and the striker are disengaged by operating the hood opener, the secondary latch and the catcher engage with each other. Is operated to rotate the catcher in the engagement releasing direction, the engagement between the catcher and the secondary latch is released, and the engine hood can be opened.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the drawings.

1 to 3, reference numeral 1 denotes an engine hood, and a grill portion 3 is integrally fastened and fixed to a front end of the engine hood by bolts and nuts 4.

A hood inner 2 coupled to the back surface of the engine hood 1 is formed with a lock mechanism entrance 5 for receiving an upper edge portion of a lock mechanism 7, which will be described later, at the center of the front end of the hood inner 2. A striker 6 is formed on the part where the mouth 5 is formed.
Is arranged so as to project downward.

The striker 6 is formed in a substantially U-shape, and is welded and fixed to the front and rear edges of the lock mechanism entrance 5 on the back side.

Reference numeral 7 denotes a vehicle body side member, more specifically, a locking mechanism that is fixed to the front surface of the radiator core upper rail 11 by bolts and nuts 22 and engages and disengages with the striker 6. The locking mechanism 7 has a secondary latch 8 Is rotatably supported by a support shaft 9.

The secondary latch 8 is biased by a set spring 10 in the direction of engagement with a catcher 12 which will be described later.

Numeral 12 is a catcher which is disposed on one side of the lock mechanism entrance 5 and engages with and disengages from the secondary latch 8. The catcher 12 is formed in a box shape with an open upper part, and one side of the upper edge. Bracket part 13 opposite to
It is rotatably attached to the catcher bracket 14 projecting to the back side of the lock mechanism entrance 5 via the support shaft 16 via the. The catcher bracket 14 is fixed to the rim of the lock mechanism entrance 5 with bolts and nuts 15.

Further, the catcher 12 is the support shaft 1 described above.
A set spring 17 mounted around 6 urges a turning force in a direction to engage with the secondary latch 8.

Reference numeral 18 denotes an operation stay which is slidably held by a holder 19 provided at a lower end portion of the rear surface of the grill portion 3,
The upper terminal is rotatably connected via a collar 21 to an arm portion 20 projecting from a side portion of the upper edge of the catcher 12 opposite to the bracket portion 13.

According to the structure of the above embodiment, when the upper edge of the secondary latch 8 interferes with the engaging edge 12a of the catcher 12 when the engine hood 1 is closed, the secondary latch 8 is formed.
Both the catcher 12 and the catcher 12 once rotate in the non-engagement direction, and the upper edge of the secondary latch 8 is
By passing through the locking edge 12a of the above, the spring force of the set springs 10 and 17 restores both to the original set position.

When the engine hood 1 is opened, when the lock mechanism 7 and the striker 6 are disengaged by operating the hood opener (not shown), the elasticity of the bumper rubber (not shown) causes the front end side of the engine hood 1 to slightly lift, and the secondary The latch 8 and the locking edge 12a of the catcher 12 engage with each other to maintain the engine hood 1 in a restrained state.

Therefore, by inserting a hand through the gap formed between the lower edge of the grill 3 and the front bumper 23 and pushing the operation stay 18 upward, the catcher 12
Rotates in the disengagement direction, the locking edge 12a disengages from the secondary latch 8, and the engine hood 1 can be opened.

Here, as described above, the secondary latch 8
Both the catcher 12 and the catcher 12 are rotatably mounted, and when the engine hood 1 is closed, they both interfere with each other and rotate. Therefore, the rotation strokes of the secondary latch 8 and the catcher 12 are small. A reliable lock can be performed.

Particularly, the secondary latch 8 is pivotally supported by the lock mechanism 7, and the pivotal support portion is exposed to the air passing through the grill portion 3 so that it is easy to stick, but the catcher 12 is on the back side of the hood inner 2. Since it is rotatably supported by and there is no stick factor due to dust adhesion, etc., it is possible to perform a reliable lock.

[0022]

As described above, according to the present invention, since the catcher with which the secondary latch engages and disengages is rotatably mounted, even if the secondary latch feels sticky, it is possible to perform a reliable lock, and The catcher can be unlocked by rotating it by operating the operation stay held on the rear surface of the grill part, and the conventional manual lever mechanism is eliminated. Therefore, the structure can be simplified and the cost can be greatly reduced. There is an advantage that the appearance of the vehicle body side member can be improved by making the area around the lock mechanism arrangement portion clear. Further, since the catcher is pivotally supported inside the hood inner, there is no fear of sticking due to adhesion of dust or the like, and the catcher can be made of an inexpensive material, which contributes to cost reduction.
