Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a vehicle bonnet lock mounting structure.

[Conventional technology]

A bonnet lock for locking the free side end of the bonnet to the vehicle body side is generally attached to a shroud upper supporting a radiator. However, since a large downward load is applied to the bonnet lock when the bonnet is closed, the above load may not be supported only by fixing the bonnet lock to the shroud upper.

Therefore, conventionally, for example, as disclosed in Japanese Utility Model Publication No. 61-205870, a hood lock stay (center stay) for reinforcing the bonnet lock and the front cross member is provided.
It is often used that the center stay is supported by the axial rigidity of the center stay.

[Problems to be solved by the device]

Since the center stay is arranged so as to vertically cross the space in front of the radiator, the air flow toward the radiator is easily disturbed by the center stay, which causes a reduction in cooling efficiency.

In addition, since the distance from the bonnet lock to the front cross member is long and the center stay must support a large load, the center stay must be long and have a large cross-sectional area. However, there is an inconvenience that this prevents the weight reduction of the vehicle.

Although the bonnet lock is attached to a position in front of the shroud upper, it is desirable to support the bonnet lock at a position close to the central axis of the shroud upper in terms of strength.

In view of such circumstances, the present invention provides a vehicle bonnet lock mounting structure that is lightweight and has a simple structure and can sufficiently support the load acting on the bonnet lock without lowering the cooling efficiency of the radiator. With the goal.

[Means for Solving the Problems]

The present invention relates to a vehicle bonnet lock mounting structure, in which a middle portion of a shroud upper supporting a radiator is bent to form a recess, and the bonnet lock is fixed in the recess, and the bonnet lock and the recess are formed. A single reinforcing member is fixed to the left and right edges of the.

[Action]

According to the above configuration, the bonnet lock is supported at a position close to the central axis of the shroud upper, and the load acting on the bonnet lock is supported by the bending rigidity of both the shroud upper and the reinforcing member. Further, since there is no vertically extending center stay or the like, air rectification toward the radiator is not disturbed.

〔Example〕

 An embodiment of the present invention will be described with reference to the drawings.

FIG. 4 shows a front portion of a vehicle equipped with the mounting structure of the present invention. This vehicle is provided with front side frames 10 extending in the front-rear direction on the left and right sides, a front cross member 12 extending in the left-right direction is fixed to a lower front end thereof, and a shroud upper 14 extending in the left-right direction is fixed to an upper front end thereof. The shroud upper 14 carries a radiator 16 as shown in FIG.
16 is shrouded upper 14 and front cross member 12
It is in a state of being located behind.

Next, the mounting structure of the bonnet lock 18 in this vehicle will be described with reference to FIGS.

A substantially central portion of the shroud upper 14 has a shape that bulges rearward by bending, thereby forming a concave portion 20 that opens forward, and a bonnet lock 18 is fixed to a substantially central front surface of the concave portion 20. Has been done. Specifically, mounting portions 181 are formed on both left and right wings of the bonnet lock 18, and the mounting portions 181 are fixed to the shroud upper 14 side with bolts 22 or the like. In the present invention, a well-known structure may be used regardless of the specific structure of the bonnet lock 18.

Further, a single reinforcing plate (reinforcing member) 24 is fixed to the front side surface of the bonnet lock 18 and the left and right edges of the recess 20. Specifically, the central portion of the reinforcing plate 24 is the bolt 22.
And the like are fixed to the front surface of the bonnet lock 18, and both left and right ends are fixed to the front surface of the shroud upper 14 with bolts 22, nuts 26, and the like.

According to this structure, the bonnet lock 18 is sandwiched between the shroud upper 14 and the reinforcing plate 24, and the large load acting on the bonnet lock 18 when the bonnet is closed causes bending rigidity of both the shroud upper 14 and the reinforcing plate 24. Since it is supported by, the attachment strength of the bonnet lock 18 can be sufficiently maintained without providing a vertically extending center stay as in the related art. Therefore, it is possible to eliminate obstacles in front of the radiator 16, and by ensuring air flow to the radiator 16, it is possible to prevent a reduction in cooling efficiency of the radiator 16 and also to reduce the weight of the vehicle. .

Moreover, in this structure, by providing the bonnet lock 18 in the recess 20, the bonnet lock 18 is substantially positioned on the center line G (FIG. 2) of the shroud upper 14, so that the shroud upper 14 has no recess. It is more advantageous in strength than the conventional structure which is not formed.

In this embodiment, the shroud upper 14 is swollen rearward to form the concave portion 20, but the shroud upper 14 may be swollen forward to form the convex portion 20 opening rearward. . In this case, the rear surface of the bonnet lock 18 and the rear surface of the shroud upper 14 (the left and right edge portions of the recess)
The reinforcing member may be fixed to the.

[Effect of device]

As described above, the present invention has a sandwich structure in which the middle portion of the shroud upper supporting the radiator is bent to form a concave portion, the bonnet lock is fixed in the concave portion, and the bonnet lock is sandwiched by the reinforcing member and the shroud upper. Therefore, the load acting on the bonnet lock can be supported without using a center stay as in the past. Therefore, while maintaining sufficient attachment strength, there is an effect that cooling air efficiency is prevented by keeping the air flow rectified in the radiator, and the weight of the vehicle can be reduced by omitting the center stay. Further, since the bonnet lock fixed in the recess is located substantially on the center line of the shroud upper, it is more advantageous in strength than the structure in which the bonnet lock is attached to the shroud upper having no recess.
