    FRONT DEFLECTOR FOR A MOTOR VEHICLE. A front deflector of a motor vehicle is retained in the front section of the motor vehicle via hitch elements or fasteners. For the stiffening of the front deflector in the central area, reinforcement ribs are provided, which extend in formations and deformations of the front section. These reinforcing ribs are preferably designed in a plate-like shape and oriented in the vertical direction and arranged running in the longitudinal direction. In order to guarantee a necessary stability in the form of the front deflector, during driving, the reinforcing ribs can be supported on the front section, where the front deflector can itself be supported on the reinforcing ribs.

    专利说明:

    [001] The invention relates to a front deflector for a motor vehicle according to the preamble of claim 1.
    [002] Front deflectors for motor vehicles are necessary to achieve a favorable coefficient of aerodynamic drag, as well as to achieve lift coefficients on the front and rear axle of the motor vehicle. The front deflector is attached to a front section of the motor vehicle and features a concave, arched and rounded incidence surface in the form of an air supply system.
    [003] The object of the invention is to provide a front deflector for a motor vehicle, which is designed in such a way that, in a driving situation with loads caused by wind or air forces, a stability of the such that its aerodynamic function can be performed.
    [004] This objective is achieved according to the invention by the features of claim 1. Other advantageous features are included in the dependent claims.
    [005] The advantages effectively achieved with the invention are based on the fact that a front deflector is provided for a motor vehicle, which is arranged on the motor vehicle in such a way that in a situation of air incidence, especially in a windy situation incident on the central portion of the front deflector, the stability of form is guaranteed, which obeys the aerodynamic function, with respect to a desired Cw coefficient, as well as a lift coefficient Cav and Cah. Furthermore, it is to be achieved through the invention that the complete reinforcement measures do not allow for the creation of markings on the outer coating. This is achieved according to the invention, in that the front deflector comprises in the central portion, on both sides of a central longitudinal axis, a region reinforced with plate-shaped reinforcing ribs, which are arranged on the upper bar of the deflector element, in which the ribs - viewed in relation to the driving direction - are arranged vertically behind the deflector element and aligned downwards, and are provided with a continuous interval distance to the deflector element, and are run in the longitudinal direction of the motor vehicle. Underneath the region of the deflector element, which is reinforced by the reinforcing ribs, an elastically flexible region of the deflector element is formed. The reinforcing ribs are thus spaced apart by the gap distance from the baffle element, and not connected to it in plane, so that no markings visible from the outside can be created on the front baffle.
    [006] This reinforced region and the subsequent flexible region of the deflector element are formed as a function of the length of the reinforcement ribs, wherein the flexible region lies below a horizontal plane running along the free ends of the reinforcement ribs and the reinforced region of the front deflector is formed above this level. Through this application and arrangement of reinforcements on the deflector, a reinforcement and support of the front deflector is achieved in the region of the main load caused by the wind. The flexible region of the front deflector serves to ensure that the front deflector, when in contact with obstacles, for example a curb, is not damaged and can be flexibly and resiliently articulated.
    [007] In addition, according to the invention, it is provided that the deflector element presents on the front side the air incidence surface and comprises, on the back side, the reinforcement ribs and that the deflector element on the upper bar of the deflector element, which is arranged above and which runs transversely, is formed in an elastic way that can be articulated within the interval distance, whereby the possibility arises, through the change of the geometry of the reinforcement, of regulating the balance between the stiffness ( aerodynamic function) and resilience or flexibility (damage reduction).
    [008] The reinforcement ribs present in an upper region, in each case, respectively, an angle-shaped notch, which is arranged correspondingly to a curvature of the front section and, in this region, the reinforcement ribs are maintained at a distance from the adjacent front section. Here, the angle-shaped notch of the reinforcing rib comprises a vertical and a horizontal rib edge, wherein the vertical rib edge is formed from a section of the rectangular rib, which is connected to the top bar, and the edge The horizontal rib is formed from a section of the posterior triangular rib.
    [009] The angle-shaped notch of the reinforcing rib overlaps the curvature of the front section from the outside and in the downward direction, wherein the rectangular rib section is arranged in a front and angular deposition of the front section. Through the gap distance formed between the deflector element of the front deflector and the front edge of the angled notch of the reinforcing rib, the deflector element is held in the front section, in the base position, by its fastening means. The horizontal rib edge of the reinforcing rib is disposed a small distance from the curvature or lower surface of the front section. During driving, the front deflector can thus be moved over the reinforcing ribs, by the prevailing air pressure, from the base position to adjustment positions and the reinforcing ribs held elastically on the upper bar are placed in this case in the front section , whereby the movement of the front deflector towards the rear, ie against the driving direction, is blocked and the front deflector thus performs its function as an air supply system.
    [010] Thus, the deflector element, depending on the occurrence of air forces opposite the driving direction, can be moved around the articulation axis from the base position to adjustment positions and present an arrangement adjacent to the ribs of reinforcement. In the adjustment positions of the deflector element, the edge of the rib of the notch of the reinforcement rib, which protrudes horizontally, is then disposed adjacent to the lower surface of the front section.
    [011] The fastening of the front deflector on the front section is preferably achieved through fastening hooks integrally formed on the top bar, which can be snapped into corresponding openings for connection with the front section. Furthermore, a connection of the front baffle with the front section can also be additionally obtained through the known plate elements, which are arranged at the free ends of the baffle element and protrude backwards along the underside of the front section and which can be attached to the front section.
    [012] In summary, according to the invention, a front deflector is obtained, which has a necessary stability during driving and which only forms slightly under loads caused by the driving wind (pressure), so that the desired aerodynamic function is fulfilled. At the same time, the front deflector must be made flexibly in a lower zone to avoid possible damage from contact with obstacles. The assembly of the deflector must be carried out with such a reinforcement that no additional costs are caused, which is achieved with a deflector with integrated reinforcement and without the application of a separate component. The use of a separate reinforcement for the deflector was thus avoided. All reinforcement measures are designed in such a way that no markings occur on the outer cladding, where mounting takes place only in one direction.
    [013] An embodiment of the invention is shown in the drawings and will be described in more detail below. The drawings show: Fig. 1 shows a view of a front deflector attached to the front section of a motor vehicle, Fig. 2 shows a bottom view of a front deflector attached to the front section of a motor vehicle, Fig. 3 shows a bottom view of the front deflector with gusset ribs, Fig. 4 shows a detailed schematic view of the gusset ribs, Fig. 5 shows a vertical section along the front shroud retained in the front section with the gusset ribs and marked gusset section, Fig. 6 shows a vertical section along the front deflector retained in the front section with fastening hooks and arrangement of the reinforcing ribs in the front section without collision with adjacent components, Fig. 7 shows an arrangement of the front deflector element in a position of base and in adjustment positions, as well as a reinforcing rib, Fig. 8 is a schematic view of an upper bar of the deflector element of the front deflector with snap-on hook hooks. shown in the front section and Figs. 9 to 11 show the formation of various lengths of the reinforcement ribs to obtain different flexible effect areas of the deflector element below the reinforcement area.
    [014] A front deflector 1 for a motor vehicle is connected to a front section 2, which is retained in the motor vehicle bodywork. The front deflector 1 forms an air supply system for the air flow L that runs opposite the driving direction F. In order to achieve a favorable aerodynamic drag coefficient Cw and air lift coefficients Cav and Cah on the shaft front and rear of the motor vehicle, the front deflector 1 is provided in its deflector element 3 with an effective aerodynamic air-incidence surface. For aerodynamic efficiency, the air bearing surface can be arc-shaped, or concave-shaped.
    [015] A central area of the front deflector 1 forms on both sides of a central longitudinal axis LA with reinforcement ribs 4 or support ribs, a reinforced section V, wherein the reinforcement ribs 4 are formed in one piece with the deflector element 3 of the front deflector 1. These reinforcing ribs 4 are preferably designed in the form of a plate and protrude - seen in relation to the driving direction F - behind the deflector element 3, and are provided with a distance of range c from the deflector element, and are constructed vertically with downward projection in the longitudinal direction of the motor vehicle. The number of reinforcement ribs 4 is applied variably as needed. Below the area reinforced by the support ribs 4 there follows a vertical, elastic and flexible area b of the deflector element 3.
    [016] This flexible region b and the reinforced area a are formed as a function of the length of the reinforcement ribs 4, 4a, 4b. As is also shown in detail in Figs. 9 to 11, the flexible region b is formed below the horizontal plane E which runs along the free ends 5 of the reinforcement ribs 4, and above this horizontal plane E forms the reinforced area a of the deflector element 3 of the front deflector 1. The elongated reinforcing rib 4a is illustrated in detail in Fig. 10 and the shortened reinforcing rib 4b is illustrated in detail in Fig. 11, wherein the pivotability of the lower area b of the reinforcing ribs 4, 4a and 4b is shown schematically with adjustment positions I e. II, from rest position R outwards. By moving the plane E downwards (Fig. 10), which defines the longer ribs 4a, the rigidity of the front deflector 1 is thus also increased. In contrast, when the reinforcing rib 4 is shortened (Fig. 11), on the contrary, the flexibility of the front deflector 1 is increased.
    [017] The deflector element 3, as well as the reinforcing ribs 4 are formed in an elastic and pivotable way in a known upper bar 6 of the deflector element 3, such that in rest position R between the deflector element 3 and the ribs of gusset 4, a continuous gap distance is formed, and an edge of ribs 12 of the rib 4 is arranged at a distance from the cladding or front section 2. These areas are characterized by positions 7 and 8. At illustrated embodiments, rib edge 12 is aligned horizontally. However, it can also be arranged at an angle.
    [018] The reinforcing ribs 4 are provided in an upper region, in each case, with an angle-shaped notch 9, which is arranged correspondingly to a curvature 10 of the front section. The angled notch 9 of the reinforcing ribs 4 has a vertical and a horizontal rib edge 11, 12, wherein the vertical rib edge 11 is formed from a section of the rectangular rib 14, which is connected to the bar upper 6, and the horizontal rib edge 12 is formed from a posterior triangular rib section 15, which is shown in greater detail in Fig. 5. The rib edge 12 of the notch 9 is, as already mentioned, arranged at distance c from the opposite surface 16 of the front section 2.
    [019] The angled notch 9 of the reinforcing ribs 4 overlaps the curvature 10 of the front section 2, from below and outwards, wherein the rectangular rib section 14 is arranged in a front and angular deposition 17 of the front section 2.
    [020] The upper bar 6 of the deflector element 3 constitutes the elastic axis of articulation or flexion axis, around which the elastic mobility of articulation of the deflector element 3 of the front deflector 1 is in such a way obtained in relation to the reinforcing ribs 4, that this deflector element 3, depending on the air forces L occurring opposite to the driving direction F, can be moved around the articulation axis from the base position R to the adjustment positions I and II and, in these positions I and II, an arrangement adjacent to the front edge 15a of the support ribs 4, and the rib edge 12 arising from the notch 9 of the reinforcing ribs 4, is disposed adjacent to the lower surface 16 of the front section 2 and thus movement of the front deflector 1 in the rearward direction, opposite to the driving direction F, is blocked.
    [021] For the fastening of the front deflector 1 in the front section 2, fastening hooks 20 are provided, which are integrally formed on the top bar 6 and which engage so by hooking in the openings 21 of the front section 2. At their free ends externally, the deflector element 3 has plate elements 22, 23 which project in a plane towards the rear, over the lower part of the front section 2, and form a support of the front deflector I in the front section 2, and which can be formed for fixation.
    [022] A mounting of the front deflector 1 on the front section 2 takes place in a main mounting direction, according to the direction of arrow P, according to Fig. 8, where mounting is carried out without a collision with the adjacent component B (Fig. 6). After assembly, the reinforcing ribs 4 are arranged in the shape of the surrounding components, such as the front section 4, so that no markings can occur on the outer cladding, which is beneficial for styling and quality assurance.
