Summary of the Invention

Problems to be Solved by the Invention

[0006] By the way, as described in Patent Documents 1 and 2, when one hood lock device is attached to the center in the vehicle width direction of the radiator support upper, the radiator support may be sheared and deformed by the lateral load input from the hood during vehicle turning, and the feeling during turning may become poor.

[0007] Therefore, an object of the present disclosure is to improve the shear rigidity of the radiator support.

Means for Solving the Problems

[0008] The radiator support of the present disclosure is a rectangular frame shape including a radiator support upper extending in the vehicle width direction and left and right vertical columns connected to the left and right ends of the radiator support upper and extending in the vehicle up and down direction, and is arranged at the front part of the vehicle to fixedly support a radiator in the frame. It is a radiator support to which a hood lock device that is arranged at the center in the vehicle width direction and supports the front end portion of the hood when the hood is closed is attached, and a reinforcing bracket attached to the radiator support upper between the hood lock attachment portion and the left and right vertical columns.

Effects of the Invention

[0009] Thereby, the shear rigidity of the radiator support is improved, and the torsional rigidity of the front part of the vehicle is improved, so that the feeling during turning and the followability to steering are improved.

Mode for Carrying Out the Invention

[0011] Hereinafter, the radiator support 10 of the embodiment will be described with reference to the drawings. Note that FR, UP, and RH shown in FIG. 1 indicate the front side, the upper side, and the right side of the vehicle including the radiator support 10, respectively. Also, the opposite directions of FR, UP, and RH indicate the rear side, the lower side, and the left side. Hereinafter, when simply using the front-rear, left-right, and up-down directions for explanation, unless otherwise specified, they indicate the front and rear in the front-rear direction of the vehicle, the left and right in the left-right direction, and the up and down in the up-down direction.

[0012] As shown in FIG. 1, the radiator support 10 is a rectangular frame-shaped structural member of the body that is disposed at the front of the vehicle and fixedly supports a radiator (not shown) inside the frame. The radiator support 10 includes a radiator support upper 11, a radiator support lower 12, left and right vertical columns 13, 14, a hood lock attachment portion 18, and reinforcing brackets 21, 22, 23.

[0013] The radiator support upper 11 is a long member extending in the vehicle width direction. The radiator support lower 12 is a long member disposed below the radiator support upper 11 and extending in the vehicle width direction. The left and right vertical columns 13, 14 connect the left and right ends of the radiator support upper 11 and the left and right ends of the radiator support lower 12 in the vehicle up-down direction. The radiator support upper 11, the radiator support lower 12, and the left and right vertical columns 13, 14 define a rectangular frame-shaped outer shape.

[0014] The hood lock attachment portion 18 is a member that connects the radiator support upper 11 and the radiator support lower 12 in the up-down direction at the center in the vehicle width direction. The hood lock attachment portion 18 has a wider width at the upper part, and bolt holes 19 for attaching a hood lock device (not shown) are provided.

[0015] Here, the hood is rotatably supported at the rear end of the front compartment in front of the vehicle, and the front end moves up and down to open and close the front compartment. The hood lock device is attached to the hood lock attachment portion 18 and fixed to the radiator support 10 at the front end portion of the hood when the hood is closed.

[0016] Reinforcement bracket 21 is a reinforcing member with an L-shaped cross-section that covers the front and upper surfaces of the radiator support upper 11 to which the upper part of the hood lock attachment part 18 is connected. A vertical rib extending in the vehicle width direction is arranged behind the upper surface of the reinforcement bracket 21. The reinforcement bracket 21 extends from the central part of the radiator support upper 11 to which the hood lock attachment part 18 is connected to the middle between the left and right vertical columns 13 and 14.

[0017] Reinforcement bracket 22 is a reinforcing member attached to the rear part of the radiator support upper 11 between the left end of the reinforcement bracket 21 and the left vertical column 13. Further, the reinforcement bracket 23 is a reinforcing member attached to the rear part of the radiator support upper 11 between the right end of the reinforcement bracket 21 and the right vertical column 14.

[0018] As described above, the radiator support 10 described has improved shear rigidity by attaching the reinforcement brackets 21, 22, and 23 to the radiator support upper 11. Therefore, when the vehicle turns, even if a lateral load from the hood is input to the hood lock attachment part 18, the radiator support 10 does not undergo shear deformation. As a result, the torsional rigidity of the vehicle front part is improved, and the feeling during turning and the followability to steering are improved.

[0019] In the radiator support 10 described above, it has been described as including three reinforcement brackets 21, 22, and 23, but it is not limited to this. The position, shape, and number of the reinforcement brackets can be freely selected as long as they are attached to the radiator support upper 11 between the hood lock attachment part 18 and the left and right vertical columns 13 and 14.
