Description

Technical Field

[0001] The utility model relates to the technical field of automobile hinges, and particularly relates to a vehicle hood hinge. Background Art

[0002] A vehicle hood is usually used to enclose the front engine compartment of the vehicle to protect the components in the engine compartment. When the hood needs to be opened, it is flipped backward to a predetermined angle. The hood and the vehicle body are usually connected by a hinge to achieve the flipping. For example, the patent with the publication number CN209585976U discloses a vehicle hood hinge. By arranging a spring above the mounting holes on the fixed hinge and the movable hinge, the influence of the hood vibration on the hinge can be reduced when the hinge is installed on the hood. However, due to the heavy weight of the hood, the impact force during opening or closing may cause damage to the spring. Summary of the Utility Model

[0016] Next, the substantial features and advantages of the present utility model will be further described in conjunction with examples, but the present utility model is not limited to the listed embodiments.

[0017] As Figures 1 to 3 shown, a vehicle hood hinge according to this embodiment includes a first connection portion 1 and a second connection portion 2. The first connection portion 1 and the second connection portion 2 are pivotally connected. The first and second connection portions are respectively connected to the hood 10 and the vehicle body 20, so that the hood 10 can rotate relative to the vehicle body 20. The first connection portion 1 and the second connection portion 2 are pivotally connected through a first mating member 3 and a second mating member 4. Two ends of the first mating member 3 are respectively connected to the first and second connection portions through a first rotating shaft 51 and a second rotating shaft 52. Two ends of the second mating member 4 are respectively connected to the first and second connection portions through a third rotating shaft 53 and a fourth rotating shaft 54. The first rotating shaft 51 and the third rotating shaft 53 are arranged in parallel. A cylinder 6 is provided in the second connection portion 2. The telescopic rod 61 of the cylinder 6 is pivotally connected to the extension plate 31 of the first mating member 3. When the hood 10 is in the closed state, the telescopic rod 61 is in the extended position, and the extended length of the telescopic rod 61 is between the maximum length and the minimum length, that is, the length of the extended part of the telescopic rod 61. When the hood 10 is opened (as Figure 3As shown in the figure, the engine hood 10 flips upward and rotates relative to the second connecting portion 2 through the first and second mating members. One end of the first mating member 3 moves downward, compressing the telescopic rod 61 so that it moves downward in the cylinder. Therefore, when the telescopic rod 61 moves downward, it is necessary to overcome the resistance to provide damping to avoid damage to the engine hood hinge. When the engine hood 10 is closed, the first mating member 3 drives the telescopic rod 61 to extend, which can also provide damping to avoid damage to the engine hood caused by too fast downward movement. Through the above technical solution, it is possible to avoid damage to the engine hood caused by too fast opening or closing speed of the engine hood.

[0018] In this embodiment, the second connecting portion 2 includes a fixed seat 21 and a mounting seat 22. The two ends of the fixed seat 21 are respectively provided with a first fixing hole 211 and a first adjusting hole 212, and the two ends of the mounting seat 22 are respectively provided with a second fixing hole 221 and a second adjusting hole 222. The first fixing hole 211 and the second adjusting hole 222 are correspondingly arranged, and the first adjusting hole 212 and the second fixing hole 221 are correspondingly arranged. Through the above technical solution, the relative position of the fixed seat 21 and the mounting seat 22 can be adjusted through the first and second adjusting holes, making the installation more flexible. The fixed seat 21 and the mounting seat 22 are locked tightly by screws. The first adjusting hole 212 is a U-shaped hole, the second adjusting hole 222 is a strip-shaped hole, and the first fixing hole 211 and the second fixing hole 222 are screw holes. After the adjustment is completed, the screws are locked into the screw holes for locking and fixing. One end of the mounting seat 22 is pivotally connected to the first mating member 3 and the second mating member 4 respectively, so that the first and second mating members can rotate relative to the mounting seat 22. The fixed seat 21 has a convex portion 213, and the convex portion 213 is correspondingly arranged with the receiving groove 223 of the mounting seat 22, so that the fixed seat 21 and the mounting seat 22 can be conveniently installed and limited. A groove 214 is provided in the convex portion 213, and the cylinder 6 is arranged in the groove 214, which is convenient for the positioning and installation of the cylinder 6. The two sides of the fixed seat 21 are provided with flat plates 215, and the flat plates 215 are provided with connecting holes 216. The fixed seat 21 is connected to the vehicle body through the connecting holes 216. The first rotating shaft 51 and the third rotating shaft 53 are U-shaped pins 7 integrally provided, so that the first and second rotating shafts can be synchronously inserted through the U-shaped pins 7, which is convenient for assembly.

[0019] A vehicle engine hood hinge in this embodiment can reduce the opening or closing speed of the engine hood through a cylinder, and avoid damage to the engine hood caused by too fast opening or closing speed of the engine hood.
