Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to a front body structure of a vehicle in which a front-opening type bonnet is openably and closably installed.

[Prior Art] Conventionally, a front cross member installed below a front end portion of a vehicle body and a shroud upper installed above the front cross member have been connected by a center stay extending in a vertical direction of the vehicle body (actually). (See Japanese Laid-Open Publication No. 62-94980). The center stay is mounted on the shroud upper so that the upper end of the center stay covers the bonnet lock mounted on the front surface of the central portion of the shroud upper, thereby supporting the load input to the vehicle body from the bonnet lock. ing.

[Problems to be Solved by the Invention] In the above-mentioned conventional front vehicle body structure, after mounting the bonnet lock on the shroud upper, it is necessary to mount the upper end portion of the center stay so as to cover the front surface of the mounting portion.
If the vehicle body is painted in this state, the paint will adhere to the bonnet lock. If paint adheres to this bonnet lock, its function may be impaired.Therefore, it is necessary to paint the center stay in a process different from the car body painting process, and then attach the bonnet lock and center stay to the shroud upper. However, there is a problem in that the painting work is complicated and the manufacturing cost is high. Further, since it is necessary to form the upper portion of the center stay to have a width larger than that of the hood lock, there is a problem that it is difficult to reduce the weight of the vehicle body.

The present invention has been made to solve the above-mentioned problems, and the coating work can be simplified and the center stay can be simplified by performing the coating while the center stay is attached to the shroud upper. It is an object of the present invention to provide a front body structure of a vehicle in which the width of the upper end of the vehicle can be reduced to reduce the weight of the vehicle.

[Means for Solving the Problems] The present invention relates to a front body member structure of a vehicle in which a front-opening type bonnet is installed so as to be openable and closable, and a front cross member installed below a front end portion of the vehicle body and an upper part thereof. Is connected to the shroud upper by a center stay that extends in the vertical direction of the vehicle body, and a mounting flange portion that is mounted on the front surface of the shroud upper is formed on one side of the upper end of the center stay. A support flange portion is formed on the other side portion so as to face the front surface of the shroud upper at a predetermined distance, and the support flange portion,
A gap for inserting a bonnet lock is provided between the shroud upper and the shroud upper.

[Operation] According to the above configuration, the vehicle body can be painted with the upper end of the center stay attached to the front surface of the shroud upper via the mounting flange portion, and then the support flange portion and the front surface of the shroud upper. A bonnet lock can be installed between and.

[Embodiment] FIG. 1 shows an embodiment of a front body structure of a vehicle according to the present invention. This front vehicle body structure includes a pair of left and right front side frames 1 extending in the front-rear direction of the vehicle body, a front cross member 2 installed below the front end portions of both front side frames 1, and a shroud upper 3 installed above the front cross members 2. And a suspension cross member 4 installed below the rear end of the front side frame 1. The front cross member 2 and the suspension cross member 4 are connected by a center frame 5 extending in the front-rear direction of the vehicle body, and the front cross member 2 and the shroud upper 3 are connected by a center stay 6 extending in the vertical direction of the vehicle body. Further, a front opening type bonnet (not shown) is installed above the front vehicle body so as to be openable and closable.

The center stay 6 has a front wall 7 as shown in FIG.
And a pair of left and right side walls 8 and 9 projecting rearward from the side portions of the front wall 7, the U-shaped cross section is formed. A mounting flange portion 10 to be mounted on the front surface of the cross member 2 is formed. Further, at the upper end of the center stay 6, a mounting flange portion 11 to be mounted on the front surface of the shroud upper 3 is formed at the base end portion of the left side wall 8 and at the base end portion of the right side wall 9. , A support flange portion 12 is formed to face the front surface of the shroud upper 3 with a predetermined gap,
A bonnet lock 13 is installed in the gap. A hole 14 is formed in the upper portion of the front wall 7 of the center stay 6 at a position facing the mounting portion of the bonnet lock 13.

The mounting flange portion 10 formed on the lower end portion of the center stay 6 is joined to the front surface of the front cross member 2 and is formed on one side of the upper end portion of the center stay 6 as shown in FIG. After the mounting flange portion 11 is joined to the front surface of the shroud upper 3 with a mounting bolt, a bonnet is formed between the support flange portion 12 formed on the other side of the upper end portion of the center stay 6 and the front surface of the shroud upper 3. The lock 13 is inserted, and the side flanges 15 and 16 of the base plate 19 of the bonnet lock 13 are joined to the front surface of the shroud upper 3 by the mounting bolts, and the support flange 12 and the base plate 19 of the bonnet lock 13 are joined together.
The front wall portion 17 and the safety lock lever 20 are joined together.

In this way, the upper end of the center stay 6 is supported by the support flange portion 12
Before mounting the bonnet lock 13, the bonnet lock 13 is mounted after the center stay 6 has been mounted on the vehicle body by providing a gap for mounting the bonnet hinge between the shroud upper 3 and the front of the shroud upper 3. In addition, with the center stay 6 attached to the front surfaces of the front cross member 2 and the shroud upper 3, it is possible to perform a coating operation including them.

Also, attach one side of the bonnet lock 13 to the center stay 6
Since the bonnet lock 13 is attached to the front surface of the shroud upper 3 with the bonnet lock 13 protruding laterally, the conventional device in which the upper portion of the center stay 6 is formed to have a size to cover the entire surface of the bonnet lock 13 Compared with this, the width of the upper part of the center stay 6 can be made smaller, and the center stay 6 can be made lighter. Further, the support flange portion 12 of the center stay 6, the front wall portion 17 of the base plate 19 of the bonnet lock 13, and the safety lock lever
Since the center stay 6 is configured to directly support the load input from the bonnet lock 13 by joining the load 20 and the bonnet lock 13, the load can be stably supported.

Further, in the above-described embodiment, since the hole 14 is formed in the upper portion of the front wall 7 of the center stay 6, an electric tool or the like is inserted into the hole 14 and the mounting bolt 18 is rotated to operate the bonnet lock 13 Base plate 19 side edge flange
There is an advantage that the mounting work of 15 can be performed easily.

[Effects of the Invention] As described above, the present invention has the center stay that connects the front cross member of the front vehicle body and the shroud upper, and is attached to the front side of the shroud upper at one side of the upper end thereof. While forming a mounting flange part that is formed, the other side part, the front face of the shroud upper, and the supporting flange part that is opposed to the bonnet lock with a gap for mounting the bonnet lock formed, therefore, before installing the bonnet lock in the gap, With the center stay attached to the vehicle body, it is possible to coat them together. Therefore, the painting work can be simplified as compared with the conventional technique in which the center stay needs to be painted in a state where it is detached from the vehicle body.

Further, since it is not necessary to cover the bonnet lock with the upper end portion of the center stay, there is an advantage that the width of the upper portion of the center stay can be reduced and the weight of the vehicle body can be reduced.
