Problems to be solved by the invention

[0006] Each of the headlamp bracket and the lamp stage is supported in a cantilever manner on the frame, and the mounting strength thereof is reinforced by a connecting rod and a tension means.

[0007] However, since the connecting rod supports the headlamp bracket in the vehicle width direction, and the tension means supports the lamp stay from an oblique direction with respect to the vehicle front-rear direction, both of them extend from the vehicle front-rear direction. It is difficult to say that the reinforcement structure is effective against the input of There is a possibility that sufficient mounting strength cannot be obtained. In particular, when the amount of headlamp offset relative to the frame increases in the vehicle width direction, the headlamp mounting strength in the vehicle front-rear direction decreases accordingly.

[0008] The reduction in the mounting strength of the headlamp increases the longitudinal vibration of the headlamp, and as a result, there is a risk that the durability of the headlamp may be reduced, such as shortening the life of the nozzle.

[0009] In addition, the increase in the longitudinal vibration of the headlamp may reduce the durability of the headlamp bracket and the like that support the headlamp bracket and may cause damage to the headlamp bracket and the like.

Accordingly, an object of the present invention is to provide a headlamp mounting structure having a mounting strength effective for suppressing longitudinal vibration without causing complication of the structure in a vehicle including a step bracket.

Means for solving the problem

[0011] A vehicle headlamp mounting structure according to the present invention that achieves the above object includes a frame, an intermediate bracket, a headlamp bracket, a headlamp, a step bracket, and a gusset. The intermediate bracket is fixed to the front end of the frame and extends outward in the vehicle width direction. The headlamp bracket is cantilevered by the intermediate bracket. The headlamp is fixed to the headlamp bracket. The step bracket is fixed to the frame at the rear of the vehicle with respect to the intermediate bracket, extends outward in the vehicle width direction, and supports the step. The gusset has one end, the other end, and an intermediate portion. One end is fixed to the head lamp bracket, and the other end is fixed to the step bracket. The intermediate portion extends rearward from the one end to the other end.

[0012] In the above configuration, the headlamp bracket is supported from the inner side in the vehicle width direction by the intermediate bracket and is also supported by the vehicle rear force by the step bracket via the gusset. Therefore, the mounting strength of the headlamp can be sufficiently secured in the vehicle width direction and the vehicle front-rear direction by a simple structure in which the headlamp bracket and the step bracket are connected by a gusset.

[0013] In particular, since the mounting strength of the head lamp in the vehicle front-rear direction is efficiently increased by supporting the vehicle rear force by the gusset, the head lamp front-rear vibration is accurately suppressed. The durability of the headlamp and the headlamp bracket can be improved.

[0014] Further, the headlamp mounting structure may include a front under-run protector bracket disposed below the front end of the frame. In this case, the intermediate bracket may be provided with a head lamp bracket support and upper and lower mounting parts! The headlamp bracket support part supports the headlamp bracket, and the upper and lower attachment parts also extend the head lamp bracket support part force inward in the vehicle width direction. The upper mounting portion is fixed to the front end portion of the frame, and the lower mounting portion is fixed to the front underrun protector bracket below the upper mounting portion.

[0015] In the above configuration, the upper mounting portion of the intermediate bracket is fixed to the front end portion of the frame, and the lower mounting portion is fixed to the front underrun protector bracket below the upper mounting portion. Is done. That is, the headlamp bracket is supported by the intermediate bracket at at least two locations in the vertical direction, and these supporting portions are attached over a sufficient range in the vertical direction. Accordingly, the mounting strength of the headlamp in the vehicle width direction and the vehicle front-rear direction can be further increased.

The invention's effect

[0016] According to the present invention, it is possible to obtain a headlamp mounting structure having a mounting strength effective for suppressing longitudinal vibration without incurring structural complexity.
