Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to the structure of a striker support portion of an automobile hood, and more particularly to the structure of a reinforcing rod of the striker support portion.

[Conventional technology]

In the conventional automobile hood 51 shown in FIG. 7, 52 is an outer panel of the hood 51;
Reference numeral 54 indicates an inner panel having an opening 53a at a proper position at the lower part, 54 indicates a hood lock provided on the vehicle body side, and 55 indicates a striker 56 that engages with the hood lock 54 to restrain the hood 51 in the closed state. The striker 5 projects downward from the inner panel 53 through the opening 53a.
6 is fixed, and the inner panel 5
3, a base member 57 is a reinforcing rod whose front and rear parts are fixed to the base member 55 so as to face in the front and rear directions, 58 is a radiator grille, and 59 is an inner panel 5 of the hood 51.
The hood 51 has a hook that fits into an opening (not shown) formed in the hood 3, and temporarily locks the hood 51 from fully opening, unless the locked state is released by manual operation by the driver. , is a secondary latch that prevents the hood 51 from opening forward.

[Problem that the invention attempts to solve]

In recent years, as automobiles have become lighter, the thickness of the outer panel 52 of the hood 51 has been reduced, resulting in a decrease in the rigidity of the outer panel 52.

In the conventional hood 51, the front end of the reinforcing rod 57 is bent forward and fixed to the inner panel 53, so that the front end of the hood 51 has the outer panel 52 and the inner panel 53
As a result, a gap 61 is formed, and the outer panel 52 located in the gap 61 has the problem of being easily deformed when external force is applied.

[Technical means to solve problems]

In the present invention, an opening is formed at a suitable position in the inner panel of the hood, the peripheral edge of which is fixed to the outer panel by forming a hollow portion below the front end of the outer panel of the hood, and is provided on the vehicle body side. a base member fixed to the upper end of the striker so that the striker engages with the hood lock and locks the hood in a closed state and projects downwardly through the opening;
A striker support part of an automobile hood, which is fixed to the upper surface of the inner panel in the hollow part, and further has a front part and a rear part of a reinforcing rod facing in the front-rear direction fixed to the front part and the rear part of the base member, respectively, The front end portion of the reinforcing rod is folded back and downward to form a folded portion, and the folded portion is fixed to the front portion of the base member, so that the front portion of the reinforcing rod is folded back and downward toward the front portion of the outer panel. The purpose is to solve the above-mentioned problems by making the shape conform to the shape of .

[Effect]

According to the present invention, a folded portion is formed by folding back the end portion toward the rear and downward at the front portion of the reinforcing rod whose front and rear portions are fixed to the base member, and the folded portion is connected to the front portion of the base member. By being fixed to the reinforcing rod, the front part of the reinforcing rod can follow the shape of the front part of the outer panel of the hood, and the rigidity of the front part of the outer panel can be strengthened.

〔Example〕

Hereinafter, one embodiment of the present invention will be described based on the drawings.

Components having the same functions as those shown in FIG. 7 are designated by the same reference numerals, and their explanations will be omitted.

In FIG. 3, the main components of the hood lock 54 are housed within a housing 2 secured to the radiator core support bracket 1. As shown in FIG. 3 is
A latch 5 is pivotally connected to the housing 2 by a shaft 4 and has an engagement groove 3a that engages the striker 56;
In addition, the wire 7 is connected to the operating lever (not shown) on the driver's seat.
The lock lever 8 is a tension spring which is locked at both ends to the latch 3 and the lock lever 5.

The latch 3 of the hood lock 54 has an engagement groove 3a that engages the striker 56 when the hood 51 is closed.
is pushed around by the striker 56 to the position shown in FIG. 3, and a part of the engagement groove 3a is locked by the stepped portion 5a of the lock lever 5, so that the lock lever 5 is locked in the lock position shown in FIG. be done.

By operating the operating lever on the driver's seat and rotating the lock lever 5 clockwise in FIG. 3, the latch 3 rotates clockwise to release the striker 56, but the hook portion of the secondary latch 59 engages with the inner panel 53.

In this state, the hood 51 is opened by manually rotating the secondary latch 59 clockwise in FIG.

A plurality of reinforcing rods 9 are provided at the rear part 55a of the base member.
The rear end portion 9a is overlapped and welded by spot welding. A folded part 9b is formed at the front end of the reinforcing rod 9 by folding the front end backward and downward.
It is welded to the front part 55b of.

By forming the folded part 9b at the front end of the reinforcing rod 9, the front part of the reinforcing rod 9 can be attached to the outer panel 52.
The front part of the outer panel 52 no longer has a gap 61 as shown in FIG. Deformation is prevented.

When fixing the reinforcing rod 9 to the base member 55,
Since a folded part 9b is formed at the front end of the reinforcing rod 9, after welding the end 9c of the folded part 9b to the front part 55b of the base member 55 as shown in FIG. Bend it in the direction of the arrow to the position indicated by
The rear portion 55a of 5 is welded in a superposed state.

According to the method of fixing the reinforcing rod 9 as described above, it is difficult to maintain the position and the radius of curvature of the folded portion 9b of the reinforcing rod 9 in an appropriate state. It is possible that each trailing end will not polymerize correctly.

The reinforcing rod 9 shown in FIG. 5 has a bent piece 9d formed on the side edge of the intermediate portion between both ends thereof. The shape and radius of curvature of the middle part of this reinforcing rod 9 are held constant by the bent piece 9d, but the position of the folded part 9b is displaced from the position shown by the solid line to the position shown by the chain line. Sometimes it happens.

The reinforcing rod 9 shown in FIG. 6 has bent pieces 9d on both side edges of the intermediate portion thereof, and bent pieces 9e on both side edges of the end portion 9c on the side of the folded portion 9b. In this way, by forming the bent pieces 9d and 9e on the middle and end sides of the folded part 9b, the folded part 9b always has the same radius of curvature at a constant position from the end 9c. will be formed.

Thereby, the rear end portion 9a of the reinforcing rod 9 can easily overlap the rear portion 55a of the base member 55, improving workability and preventing variations in the shape of the parts.

[Effect of idea]

According to the present invention, a folded portion is formed by folding back the end portion toward the rear and downward at the front portion of the reinforcing rod whose front and rear portions are fixed to the base member, and the folded portion is connected to the front portion of the base member. By being fixed to the reinforcing rod, the front part of the reinforcing rod is formed to follow the shape of the front part of the outer panel of the hood, increasing the rigidity, and making it possible to prevent the front part of the outer panel from deforming.
