The hinge support includes a horizontal plate portion fixed to the vehicle body and a vertical plate portion supporting the second end of the hinge arm. The vertical plate portion is erected and extends in both the vehicle height direction and the vehicle front-rear direction from the first end of the horizontal plate portion in the vehicle width direction. The hinge arm of the hood hinge is provided with arm reinforcing ribs and the vertical plate portion of the hinge support is provided with support reinforcing ribs extending in the vehicle height direction. The support reinforcing ribs are not provided on the ridge of the connecting portion between the vertical plate portion and the horizontal plate portion.

[0004] However, this technology does not involve the technical problems and technical solutions of the present application. Summary of the Utility Model

The hinge support bracket 1 is connected to the vehicle body, and the front hinge 3 is connected to the hood. For the deficiencies in the prior art, the above structure proposes an improved technical solution. When setting the structure of the hood hinge, instead of setting an integral hood hinge, the hood hinge is divided into multiple components, namely the hinge support bracket 1, the rear hinge connecting member 2, and the front hinge 3. When processing the hood hinge, the hinge support bracket 1, the rear hinge connecting member 2, and the front hinge 3 are respectively processed and formed, thereby reducing the manufacturing difficulty and also reducing the cost. When the hood hinge needs to be used, the hinge support bracket 1, the rear hinge connecting member 2, and the front hinge 3 are connected, and the connection is achieved through bolts to form an integral hood hinge structure, that is: the hinge support bracket 1 is connected to one end of the rear hinge connecting member 2, the other end of the rear hinge connecting member 2 is connected to the front hinge 3, the hinge support bracket 1 is connected to the vehicle body, and the front hinge 3 is connected to the hood. In this way, even if the hood hinge is damaged, only the damaged hinge support bracket 1, rear hinge connecting member 2, and front hinge 3 need to be disassembled and replaced correspondingly, without the need to scrap the entire hood hinge. This not only makes the disassembly and replacement convenient, but also avoids waste of the hood hinge, improves the utilization rate, and reduces the cost.

The hinge support bracket 1, the rear hinge connecting member 2, and the front hinge 3 are all structures made of metal materials, and the strength is guaranteed.

[0030] For the separable hood hinge structure described in the present utility model, when setting up the structure of the hood hinge, instead of setting up an integral hood hinge, the hood hinge is divided into multiple components, namely, hinge support bracket 1, rear-end hinge connecting piece 2, and front-end hinge 3. During the processing of the hood hinge, the hinge support bracket 1, rear-end hinge connecting piece 2, and front-end hinge 3 are respectively processed and formed, thereby reducing the manufacturing difficulty and also reducing the cost. When the hood hinge needs to be used, the hinge support bracket 1, rear-end hinge connecting piece 2, and front-end hinge 3 are connected, and the connection is achieved through bolts to form an integral hood hinge structure, that is: the hinge support bracket 1 is connected to one end of the rear-end hinge connecting piece 2, the other end of the rear-end hinge connecting piece 2 is connected to the front-end hinge 3, the hinge support bracket 1 is connected to the vehicle body, and the front-end hinge 3 is connected to the hood. In this way, even if a part of the hood hinge is damaged, only the damaged hinge support bracket 1, rear-end hinge connecting piece 2, and front-end hinge 3 need to be disassembled and replaced correspondingly, and there is no need to scrap the entire hood hinge. It is not only convenient to replace but also avoids waste of the hood hinge, improves the utilization rate of parts, and reduces the cost.
