A hood hinge mounting reinforcement plate structure

Abstract

This utility model discloses a hinge mounting reinforcement plate structure for a hood. The reinforcement plate (10) is divided into a flat plate part and a bent part. The bent part is an extension plate (11) that extends outward from the edge of the flat plate part. The bent part is provided with a support leg that is connected to the outer plate of the hood. An additional reinforcement plate (10) is added between the inner and outer plates of the hood, and the reinforcement plate (10) is in close contact with the surface of the inner and outer plates of the hood. It is connected to the inner plate of the hood and the movable leaf plate of the hinge through the flat plate part, which plays the role of strengthening the inner plate of the hood. At the same time, it also provides a gas spring mounting position to increase its installation strength. By connecting the support leg of the bent part to the outer plate of the hood, after CAE multi-round analysis, the angle of the support leg connecting the inner and outer plates of the hood is 30°~40°. When the outer plate of the hood is pressed with force, the hood is reduced to prevent dents and the hood's anti-dent performance is improved. At the same time, it also increases the buffering effect when pedestrians collide with the hinge area, reducing the head injury value and improving the pedestrian protection score.

Description

Technical Field

[0001] This utility model belongs to the field of automotive technology. Specifically, this utility model relates to a hood hinge mounting reinforcement plate structure. Background Technology

[0002] Traditional hinge mounting reinforcement plates are simply flat structures that are tightly attached to the inner panel of the hood and connected to it by welding. During road tests, cracking often occurs, and there is a lack of connection between the hood and the outer panel, which is detrimental to the hood's dent resistance. At the same time, the low-slung design of the car results in a relatively small front compartment space. When a head hits the hood hinge in a collision, the head injury value increases, the pedestrian protection score decreases, and it affects the passing of regulations or star ratings.

[0003] A patent application with patent number 201520965991.7, published on May 16, 2016, discloses a hood hinge mounting plate reinforcement structure and an automobile. The hood hinge mounting plate reinforcement structure includes: a hood hinge mounting plate; and a hinge mounting reinforcement plate located on and fixedly connected to the hood hinge mounting plate. The hood hinge mounting plate and the hinge mounting reinforcement plate are fixed to the hood hinge. This invention, by adding a hinge mounting reinforcement plate, makes the hood hinge mounting plate structure more robust, while occupying less space and adding less weight. The structure is sturdy and compact, improving the strength and rigidity of the hood hinge mounting point, enabling it to withstand greater loads, and solving the problem of excessive hood sway caused by insufficient strength at the hood hinge mounting point.

[0004] In the current technology, with the rapid development of the automotive industry and the rapid rise of electric vehicles, the traditional hood hinge mounting plate, which only serves to improve the rigidity of the inner hood panel, can no longer meet the current requirements. Due to the requirements of lightweighting of automobiles, aluminum and aluminum alloys are widely used in the hoods of electric vehicles. However, aluminum products generally have low hardness and rigidity. When the outer hood panel is pressed down by hand, dents will appear, which is not conducive to the hood's dent resistance. At the same time, the compact space of the hood's front compartment is not conducive to pedestrian collision protection at the hinge position. Utility Model Content

[0018] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the utility model concept and technical solution, and to facilitate its implementation.

[0019] Please see Figure 1-3 A hood hinge mounting reinforcement plate structure is disclosed. The reinforcement plate 10 is divided into a flat section and a bent section. The bent section is an extension plate 11 extending outward from the edge of the flat section. The bent section is provided with a support leg connected to the outer hood panel. The flat section is connected to the inner hood panel and the movable flap of the hinge, which strengthens the inner hood panel and provides a gas spring mounting position to increase its installation strength. By connecting the support leg of the bent section to the outer hood panel, CAE multi-round analysis shows that the angle between the support leg and the inner and outer hood panels is 30°~40°. When the outer hood panel is pressed, the hood is reduced indentation, improving the hood's anti-dent performance. At the same time, it increases the buffering effect when pedestrians collide with the hinge area, reducing head injury value and improving pedestrian protection score.

[0020] There are three bending sections, namely the first support leg 7, the second support leg 8, and the third support leg 9. The flat plate is long and narrow, with the long side divided into a straight side and a curved side. The bending sections are located on the curved side and the short side edge of the flat plate. The support legs on the bending sections are set along the edge of the flat plate, which can ensure the strength and stability of the connection while minimizing the number of structures.

[0021] The support leg protrudes from the surface of the bent section, facilitating connection with the outer panel of the cover.

[0022] The support legs are connected to the outer panel of the cover via adhesive strips; installation is simple.

[0023] The upper part of the flat plate of the reinforcing plate 10 is provided with two hinge mounting holes, namely the first hinge mounting hole 1 and the second hinge mounting hole 2; the reinforcing plate 10 is tightened with bolts in the hinge mounting holes to achieve the fit of the movable leaf plate of the hinge to the inner plate of the cover.

[0024] The flat plate portion of the reinforcing plate 10 is provided with a main positioning hole 3; the hinge mounting reinforcing plate 10 is positioned in the inner plate of the cover by the main positioning hole 3 and the local profile.

[0025] The plate portion of the reinforcing plate 10 is provided with a secondary positioning hole 4; the position of the gas spring mounting point is located by means of the secondary positioning hole 4 and the local profile.

[0026] The flat plate portion of the reinforcing plate 10 is provided with a leakage hole 5 to prevent water residue.

[0027] The flat plate of the reinforcing plate 10 is provided with a gas spring mounting hole 6; the bolts are tightened through the gas spring mounting hole 6, and the ball pin of the gas spring is installed on the inner plate of the cover, ensuring the rigidity of the cover and the safety during driving and opening and closing, and realizing that the mounting reinforcing plate 10 of the hinge and the gas spring uses the same structure, reducing development costs.

[0028] Working principle: The hinge mounting reinforcement plate structure connecting the inner and outer plates of the cover improves the dent resistance of the outer plate of the cover, while also acting as an energy absorber and buffer, improving the pedestrian protection score. The reinforcement plate 10 has a main positioning hole 3 and a secondary positioning hole 4 for positioning the reinforcement plate 10. At the same time, the parts where the main positioning hole 3 and the secondary positioning hole 4 are located have been deformed so that the local surface where the main positioning hole 3 and the secondary positioning hole 4 are located can position the hinge mounting reinforcement plate 10 on the inner plate of the cover, which facilitates the subsequent bolt tightening and installation. The main positioning hole 3 is mainly used to position the hinge mounting hole, and the secondary positioning hole 4 is mainly used to position the gas spring mounting point. After the hinge mounting reinforcement plate 10 is installed, the bolts are tightened through the gas spring mounting hole 6, and the ball pin of the gas spring is installed on the inner plate of the cover to ensure the rigidity of the cover and the safety during driving and opening and closing. The hinge and the gas spring mounting reinforcement plate 10 use the same structure, reducing development costs. The surface of the reinforcing plate 10 has multiple grooves, which makes the surface shape of the reinforcing plate 10 change. It can be adapted to the shape of the inner and outer plates of the cover, so that the reinforcing plate 10 can fit more closely to the inner and outer plates of the cover, reducing gaps and abnormal noises. At the same time, it can also play a certain role in positioning and facilitate installation. After the reinforcing plate 10 is connected to the inner panel of the cover, the outer side of the flat plate of the reinforcing plate 10 is provided with a bent part. The bent part is an outwardly extending extension plate 11 set at the edge of the flat plate. The bent part is inclined relative to the flat plate, while the part with the support legs is parallel to the flat plate. At the same time, the bent part is provided with a weight-reducing groove and a reinforcing rib, which improves the bending strength. The support legs of the bent part are connected to the outer panel of the cover by an adhesive strip. The angle between the support legs and the inner and outer panels of the cover is 30°~40°. When the outer panel of the cover is pressed down, the cover is reduced and the cover's anti-dent performance is improved. At the same time, it also increases the buffer effect when pedestrians collide with the hinge area, reducing the head injury value and improving the pedestrian protection score.

[0029] The technical effects of this utility model are as follows: the flat plate is connected to the inner plate of the cover and the movable plate of the hinge, which strengthens the inner plate of the cover; the support leg of the bent part is connected to the outer plate of the cover, which not only supports the outer plate of the cover, but also acts as a buffer when a pedestrian collides with the hinge area, thus improving the pedestrian protection score; at the same time, it also provides a gas spring installation position to increase its installation strength.
