Description

The utility model relates to the field of automotive industry, in particular to the wing of a car, which is installed in front of the car and is a front side panel.

The prior art design of the front wings for a passenger car (analogues - DE patent No. 3724193, IPC - B62D 25/16, publication date 03.03.1988, PCT patent No. 9205064, IPC - B62D 25/16, publication date 02.04.1992 d) made of sheet steel and having complex geometry and numerous flanges, holes for attaching the wing to the car, which leads to design complexity and to increased costs for the manufacture and installation of wings.

The closest technical solution is the front wing for the vehicle (prototype - RF patent No. 50959, IPC - 62D 25/08, publication date 01/27/2006) made in the form of an all-stamped sheet metal part, during operation the wing undergoes corrosion, which leads to to short service life. The wing contains upper vertical and horizontal flanges for connection with the body, and the upper horizontal flange is located below the upper generatrix of the wing on which is formed

ledge made along the upper belt, lower vertical flange for communication with the sidewall of the body and an arched cut along which a flange is formed for connection with the wing shield

The objective of the utility model is to create a wing structure that does not corrode during operation, to ensure a constant gap between the wing and the bumper, and also to be easily manufactured and installed, which reduces the cost of installing the wing and replacing it during repair.

To solve this problem, we propose a front wing for a passenger car made of plastics and containing an upper horizontal flange with an L-shaped cross section located below the upper wing generatrix on the back along the upper belt, and also an upper vertical flange, which is made in the form of a volumetric element with a [-shaped cross-section and having a U-shaped recesses, a lower vertical flange designed to communicate with the sidewall of the body, and an arcuate notch. A reinforcing element is arranged along the trailing edge of the rear surface of the wing, detachably connected to the wing and made with a limb, the angle of which is directed inside the wing and on which stiffeners are made.

A comparison of the claimed technical solution with the level of technology for scientific, technical and patent documentation on the priority date in the main and related sections shows that the set of essential

the signs of the claimed decision was not known - therefore, it meets the condition of patentability “novelty”.

The proposed technical solution is industrially applicable, because can be manufactured industrially, efficiently, reproducibly, therefore, meets the patentability condition “industrial applicability”.

The essence of the technical solution is illustrated in the drawings.

The front wing (see figure 1) for a passenger car is an integral part of complex spatial shape made of plastics. The wing is made in the form of an elongated L-shaped element with an arcuate notch for the front wheel. A decorative groove (1) is formed on the front surface of the wing, which goes to “no” towards the front side edge (2) of the wing

(the area that joins the headlight and the front bumper) and visually dividing the wing into the upper and lower zones.

Along the upper zone from the upper generatrix (3) of the wing through smooth rounding directed to the rear side of the wing, an upper horizontal flange (4) with an L-shaped cross section is made, having holes (5) for attaching the wing to the body (Fig. 2, 3) and vertical triangular ribs (6) stiffness on the angular bend of the flange (4). The horizontal flange (4) is mounted under the hood when installed in the vehicle.

On the lower wing belt from the side of the front leading edge (2), an upper vertical flange (7) is made in the form of a volumetric element (Figs. 4, 8) with [-shaped cross section and U-shaped recesses (8), on the bottom of which are made holes (9) for attaching the wing to the body. On the upper horizontal part of the volumetric element (7), in the recess between the flange (7) and the wing surface, rectangular protrusions (10) are made to provide a constant gap between the wing and the bumper (not shown) (Fig. 1).

The lower vertical flange (11) is located in the lower wing zone, with an opening for attaching the wing to the body.

Along the trailing edge (12) (in the area of the doorway), from the rear surface of the wing there is an reinforcing element (13), which adds rigidity to the wing along the trailing edge (12). The reinforcing element (13) is a complex polygonal part, which is connected to the wing by a detachable bolted connection by means of L-shaped flanges (14) made integrally with the wing. To fix the reinforcing element (13) in the upper part, on the back surface of the wing, a hole (15) is made, into which the upper part of the reinforcing element (13) enters (Fig. 7), and the lower part of the reinforcing element (13) is attached directly to wing by bolting. The reinforcing element (13) is made with a limb, the angle of which is directed inside the wing. To reinforce the stiffness of the trailing edge (12) of the wing, triangular stiffeners (16) are made on the angular bend of the reinforcing element (13). For fastening the wing to the body, holes (17) are made on the reinforcing element (13).

The above-described wing is characterized by the absence of corrosion during operation, is easily installed on the body and does not require additional technological operations designed for a metal wing.
