[0005] To achieve the above objectives, this utility model provides a hinge mechanism for opening and closing a car hood, including a body part, a hood part, and a locking connection assembly. The locking connection assembly includes a fastening bolt, a washer, a bushing, and a fastening screw. The hood part is disposed on one side of the body part, and the locking connection assembly is connected to both the body part and the hood part. The body part has an elliptical hole that is movably fitted with the fastening screw. The hood part has a mounting hole that is adapted to the fastening screw. The fastening bolt is threadedly connected to the fastening screw and is located on the outer side wall of the fastening screw, and the fastening bolt contacts the left side of the hood part. The washer is disposed on the outer side wall of the fastening screw and contacts the right side of the hood part. The bushing is detachably connected to the fastening screw and is located on the outer side wall of the fastening screw, and the bushing contacts both the washer and the hood part.

[0006] The locking connection assembly further includes a limiting member, which is fixedly connected to the body part and located on one side of the body part, and the limiting member is adapted to the fastening bolt.

[0007] The body parts have rounded chamfers.

[0008] The vehicle body component has a first groove.

[0009] The hood component has a second groove.

[0010] This utility model discloses a hinge mechanism for an automotive hood opening and closing component. During assembly, the gasket, bushing, and hood component are sequentially placed on one side of the vehicle body component, aligning the mounting hole, bushing, gasket, and elliptical hole. Then, the fastening screw is sequentially passed through the mounting hole, bushing, gasket, and elliptical hole, and tightened in conjunction with the fastening bolt. This process allows adjustment of the position of the fastening screw within the elliptical hole, achieving Z-axis adjustment of the hinge and thus absorbing dimensional and shape deviations between the vehicle body and the hood. After adjustment, tightening the fastening screw locks the vehicle body component to the vehicle body, ensuring the final positioning rigidity and connection strength of the hinge. This method solves the problem that the assembled vehicle body component cannot be fine-tuned in the Z-axis direction, has weak fine-tuning capability, and insufficient compensation, affecting the precision requirements of the vehicle body and hood component.

[0016] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0017] Please see Figures 1-3 , Figure 1 This is a structural schematic diagram of the hinge mechanism for the opening and closing of an automotive hood according to this utility model. Figure 2 This is an exploded view of the hinge mechanism for opening and closing a car hood according to this utility model. Figure 3 This is a structural schematic diagram of the vehicle body component of this utility model.

[0018] This utility model provides a hinge mechanism for opening and closing a car hood, including a body part 101, a hood part 102, and a locking connection assembly. The locking connection assembly includes a fastening bolt 103, a washer 104, a bushing 105, a fastening screw 106, and a limiting member 107.
