[0003] The existing engine hood hinge consists of a fixed seat, a pin shaft, and a rotating arm. The fixed seat is installed on the vehicle body, and the rotating arm is riveted to the fixed seat through the pin shaft and can rotate around the pin shaft. The engine hood is opened during vehicle maintenance and consumable supply. According to the layout of the engine and the vehicle, there are several ways to open and close the engine hood: one is to arrange a special engine hood support rod. When opening the engine hood, one hand lifts the engine hood, and the other hand picks up the support rod and puts it into the support hole on the engine hood to keep the engine hood in the support position. This solution has many parts, a complex system, and a cumbersome operation process; the other is to support the load of the engine hood through support rods, gas springs, etc. to keep it open. In order to install support rods, gas springs and other components, this solution needs to provide additional installation space, and the production cost will also increase.

[0004] For this purpose, a hood hinge for a motor vehicle is proposed. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0025] Reference Figures 1 to 5 As shown, this embodiment provides a hood hinge of a motor vehicle, comprising: a support base 1, a rib plate 2 is fixedly connected to one side of the support base 1, a hinged end 3 is protruded at one end of the rib plate 2, a rotating arm 4 is hinged at the upper end of the hinged end 3, and a sliding groove 5 is provided at the bottom end of the rotating arm 4; a support arm 6 is hinged at the other end of the rib plate 2 away from the hinged end, a sliding head 7 is fixed to the end of the support arm 6 away from the rib plate 2, the sliding head 7 is slidably connected in the sliding groove 5, and a locking groove 8 is provided at the end of the sliding groove 5 away from the hinged end 3.

[0026] The engine hood hinge of the motor vehicle is symmetrically installed on both sides of the engine hood, the support seat 1 is installed on the vehicle body, and the rotating arm 4 is installed on the engine cover plate. In the closed state, the sliding head 7 is close to one end of the hinged end 3 in the sliding groove 5, and the rotating arm 4 is close to the supporting seat 1. When opening, the front side of the engine hood is gradually raised, so that the rotating arm 4 rotates with the hinged end 3 as the axis, and the sliding head 7 gradually slides in the sliding groove 5 to the end away from the hinged end 3 until the sliding head 7 slides into the clamping groove 8. Due to the weight of the engine hood itself, the sliding head 7 can be clamped in the clamping groove 8. At this time, the engine hood is fixed in the open position, and the engine maintenance and consumables can be added; when the engine hood needs to be closed, the engine hood is lightly lifted, and the sliding head 7 is disengaged from the clamping groove 8, and then the engine hood is gradually lowered to rotate the rotating arm 4, and the sliding head 7 gradually moves toward the hinged end 3 until the engine hood is closed. The utility model has a simple structure, saves installation space, can be operated with one hand, is easy to operate, and has low cost, and is suitable for mass production.

[0027] According to a further optimization scheme, the sliding head 7 is a round head which is embedded in the sliding groove 5 , and the locking groove 8 is a hemispherical groove which is opened inward on the basis of the sliding groove 5 , and the sliding head 7 can be locked in the locking groove 8 .

[0028] The sliding head 7 is round and easy to slide. It is embedded in the sliding groove 5. A blocking protrusion is provided at the bottom of the sliding head 7, which is not easy to fall out. The locking groove 8 is grooved inward again on the basis of the sliding groove 5 and is based on the shape of the sliding head 7. Therefore, the sliding head 7 can be embedded in the locking groove 8 for locking.

[0029] According to a further optimized solution, the connection between the locking groove 8 and the sliding groove 5 is smoothly connected.

[0030] The locking groove 8 and the sliding groove 5 are smoothly connected to each other to prevent the sliding head 7 from sliding into / out of the locking groove 8 smoothly.

[0031] According to a further optimization scheme, the maximum angle between the support arm 6 and the support base 1 is smaller than a right angle.

[0032] The angle smaller than the right angle effectively limits the rotation direction of the support arm 6 , thereby preventing the support arm 6 from rotating toward the side away from the hinge end 3 .

[0033] According to a further optimized solution, the hinged end 3 and the rotating arm 4 , and the rib plate 2 and the supporting arm 6 are hinged by bolts 9 .

[0034] According to a further optimized solution, a hinge block 10 is fixed to the hinged end of the support arm 6 , the support arm 6 is hinged to the bolt 9 via the hinge block 10 , and the side surface of the hinge block 10 is parallel to the side surface of the rib plate 2 .

[0035] The side of the hinge block 10 close to the rib plate 2 is flat, and the gap between the side of the hinge block 10 and the rib plate 2 is small, which can make the hinge between the support arm 6 and the rib plate 2 more stable and prevent the support arm 6 from shaking left and right.

[0036] According to a further optimized solution, a connecting plate 11 is fixedly connected to the rotating arm 4 in the direction opposite to the supporting seat 1 .

[0037] The connecting plate 11 is used to fix the rotating arm 4 and the engine cover.

[0038] According to a further optimized solution, a plurality of connection holes 12 are provided on the connection plate 11 and the support seat 1 .

[0039] The connection holes 12 are used to pass screws, bolts 9, etc., so as to fix the connection plate 11 on the engine hood or fix the support base 1 on the vehicle body.

[0040] The parts not described in detail in the present invention are all conventional technical means known to those skilled in the art.

[0041] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0042] The embodiments described above are only descriptions of the preferred methods of the present invention, and are not intended to limit the scope of the present invention.
