Reinforced structure of motor vehicle hood

The present invention relates to a reinforcing structure for a motor vehicle hood, and more particularly to a structural strength for reinforcing a hood of a motor vehicle.

As shown in FIG. 1 to FIG. 4, the conventional motor vehicle hood A is mainly provided with an intake chamber A1 and an exhaust chamber A2, wherein the intake chamber A1 has an intake port A3 on the side thereof. The air inlet A3 introduces air into the air inlet chamber A1, and then passes through an air filter core B to filter the suspended particles in the air to prevent the suspended particles in the air from injuring the engine.

However, the motor vehicle hood A is exposed to the outside for a long period of time without any protection, and is therefore often susceptible to collision by external forces, causing damage. Therefore, the creator of the case filed a patent application for "Shell Reinforcement Structure" in the Republic of China on July 31, 2006, and published the announcement No. M308846, which was applied to the intake chamber of the hood A of a motor vehicle. In the A1 and the exhaust chamber A2, a plurality of ribs C are formed on the inner surfaces of the inlet chamber A1 and the exhaust chamber A2 of the motor vehicle hood A, and the ribs C are arranged in a honeycomb state in the air intake The inside of the surface of the chamber A1 and the exhaust chamber A2 is used to increase the strength of the casing of the overall motor vehicle hood A.

As shown in the third figure, the ribs C are vertically and horizontally staggered in a honeycomb state, and the honeycomb state is a hexagonal shape. Therefore, an angle θ of 120° is formed at the intersection of the adjacent edges of the two ribs. This angle θ is easy to cause stress when the motor vehicle hood A is injection-molded. The phenomenon of concentration, and the phenomenon of fracture at the angle θ, is also prone to the problem that the filler is not sure.

In addition, the creator of this case is in the air intake chamber A1 and exhaust of the motor vehicle hood A. A reinforcing structure is added to the chamber A2, but after long-term use, it is found that the exhaust passage A4 of the motor vehicle hood A between the intake chamber A1 and the exhaust chamber A2 is insufficient in strength. The existing exhaust passage A4 between the inlet chamber A1 and the exhaust chamber A2 extends between the outer cover A5 and the inner cover A6 only by an extension plate A7 between the outer cover A5 and the inner cover A6. .

However, this extension plate A7 cannot effectively increase the outer cover of the exhaust passage A3. The structural strength of the plate A5, and thus the impact of the external force, tends to cause damage to the motor vehicle hood A at the outer cover A5, which reduces the service life of the motor vehicle hood A.

The trick is how to provide a structural strength that enhances the hood of a motor vehicle, which is the problem that the creative is trying to solve.

To achieve the above objective, the motor vehicle hood of the present invention has an intake chamber, an exhaust chamber and at least one exhaust passage, and the exhaust passage is disposed between the intake chamber and the exhaust chamber, and in the exhaust passage The utility model is formed by an outer cover plate, an inner cover plate and two side plates respectively connected to the outer cover plate and the two end sides of the inner cover plate, wherein the inner side of the surface of the inlet chamber and the exhaust chamber protrude inwardly. a plurality of ribs are disposed on the inner side of the surface of the inlet and outlet chambers in a polygonal cross-sectional manner, and a circular arc-shaped guide angle is formed between any two adjacent ribs; wherein, the outer cover The plate extends at least one reinforcing plate in the direction of the inner cover, the reinforcing plate has an angle with the outer cover, and the end of the reinforcing plate is provided with a connecting plate, and the connecting plate and the outer cover are parallel to each other and connected The distance between the plate and the outer cover is smaller than the distance between the connecting plate and the inner cover.

Therefore, the reinforcing plate and the connecting plate are used to strengthen the exhaust passage close to the motor vehicle engine. The strength of the outer cover of the cover is to prevent the outer cover from being damaged by the impact of the external force, thereby improving the strength of the overall motor vehicle hood.

Wherein, the connecting plate and the inner cover further have a reinforcing plate, and the reinforcing plate has two The ends are respectively connected to the connecting plate and the inner cover.

Figure 11 is an enlarged schematic view showing a third embodiment of the creation of the exhaust passage.

As shown in FIGS. 5 to 9, the motor vehicle hood of the present invention has an intake chamber 11, an exhaust chamber 12, and an exhaust passage 13, which is disposed in the intake chamber 11 and Between the exhaust chambers 12, the exhaust passage 13 is composed of an outer cover 20, an inner cover 30 and two side plates 40 connected to the opposite end sides of the outer cover 20 and the inner cover 30.

The inner surface 14 of the air inlet chamber 11 and the exhaust chamber 12 protrude inwardly with a plurality of ribs 70, and the ribs 70 are arranged in a polygonal state in the air inlet chamber 11 and the exhaust chamber 12 The inner side surface 14 and the intersection of each of the two adjacent ribs 70 of the ribs 70 are respectively formed with a circular arc guide angle R. The polygons referred to in this creation can be trigonometry, quadrilateral, pentagon, hexagon, octagon, etc. In this creation, the hexagon is the main implementation.

Therefore, with the design of the circular arc guide angles R, the integral motor vehicle hood 10 can be injection molded, which can improve the fluidity of the resin and make the formation of the motor vehicle hood 10 easier. Moreover, the design of the arc guide angles R can solve the phenomenon of stress concentration in the prior art and improve the structural strength of the motor vehicle hood 10.

In the present embodiment, the outer cover 20 mainly refers to the plate body of the exhaust passage 13 near the outer side of the motor vehicle hood 10, and the inner cover plate 30 refers to the exhaust passage 13 near the inner side of the motor vehicle hood 10. The board body is characterized in that at least one reinforcing plate 50 extends from the outer cover 20 toward the inner cover 30, and the reinforcing plate 50 forms an angle with the outer cover 20.

In this embodiment, five reinforcing plates 50 are disposed on the outer cover 20, and each reinforcing plate 50 and the outer cover 20 are vertically disposed so that each reinforcing plate 50 and the outer cover 20 are disposed. An angle of 90°. However, in practical applications, the reinforcing plate 50 may also be obliquely extended from the outer cover 20 toward the inner cover 30 at an angle such that an angle is formed between the reinforcing plate 50 and the outer cover 20, and the angle is less than 90°. The number of the reinforcing plates 50 can be increased or decreased according to the width of the outer cover 20 (ie, the distance between the two side plates 40), that is, the longer the length of the outer cover 20, the greater the number of the reinforcing plates 50. On the contrary, when the length of the outer cover 20 is shorter, the number of the reinforcing plates 50 is smaller.

The connecting plate 60 is disposed at the end of the reinforcing plate 50, and the connecting plate 60 is parallel to the outer cover 20. In the embodiment, the connecting plate 60 extends along the two side plates 40 and the two side plates 40. The connection is made, and the distance between the connecting plate 60 and the outer cover 20 is smaller than the distance between the connecting plate 60 and the inner cover 30.

Thereby, the structural strength of the outer cover 20 is increased by the reinforcing plate 50 extending in the direction of the inner cover 30 and the connecting plate 60 at the end of the reinforcing plate 50, so that the outer cover 20 is subjected to an external force. It can maintain a certain structural strength without avoiding damage to the outer cover 20 to protect the integrity of the motor vehicle hood.

Referring to FIG. 10 again, it is a second embodiment of the present invention. In this embodiment, mainly in the direction of the connecting plate 60 facing the inner cover 30, a reinforcing plate 80 extending from the reinforcing plate 80 is formed. The two ends are respectively connected to the connecting plate 60 and the inner cover 30 to utilize the supporting force generated by the reinforcing plate 80 on the connecting plate 60, thereby further reinforcing the structural strength of the outer cover 20.

Please refer to FIG. 11 again, which is the third embodiment of the present invention. In this embodiment, the two reinforcing plates 50' are mainly disposed above the outer cover 20', and the two ends of the connecting plate 60' are Connected to the last section of the two reinforcing plates 50', and connected to the two side plates 40', and the connecting plate 60' and the inner A reinforcing plate 80' is also disposed between the cover plates 30', so that the structural reinforcement effect of the outer cover 20' can be achieved.

Although the technical content of the present invention has been disclosed in the above preferred embodiments, it is not intended to limit the present invention, and any modifications and refinements made by those skilled in the art without departing from the spirit of the present invention should be encompassed by the present invention. Therefore, the scope of protection of this new type is subject to the definition of the scope of the patent application.
