Description

Technical Field

[0001] The present invention relates to the adaptive connection of automobile exterior functional parts, and in particular to a connection structure between a headlight and an air intake grille. Background Art

[0002] Most automotive exterior components serve both decorative and functional purposes, such as headlights and grilles. Headlights not only provide lighting for driving safety but also offer significant decorative benefits. The accompanying grilles also direct cool airflow and provide a distinct identity for the vehicle. The uniformity and size of the gaps and surface differences between the headlights and grilles significantly impact vehicle noise and wind resistance, and directly impact the vehicle's exterior appearance.

[0003] Titled "A Y-axis Positioning and Adjustment Mechanism for a Front Bumper Grille" (Document No. CN 204452006U, hereinafter referred to as Document 1), this document provides a solution for resolving the Y-axis gap between the front bumper grille 1 and the headlight 2. The slider 4 in this document is provided with a positioning pin hole 5, into which the headlight's positioning pin fits, thereby connecting the slider 4 to the headlight 2 corresponding to the end of the slide rail of the front bumper grille 1. This solution, as can be seen, only adjusts the Y-axis gap, or gap, between the front bumper grille 1 and the headlight 2.

[0004] Titled "An Improved Structure for Matching Automobile Front Bumper and Headlights" (Document No. CN203854599U, hereinafter referred to as Document 2), the slot 11 of the limiting flange 1 on the front bumper 4 matches the hook 21 on the limiting bracket 2 on the front module 3, thereby defining the Z-axis coordinate of the limiting flange 1 on the front bumper 4. The headlight 5 is fixedly connected to the front module 3, thereby defining the Z-axis coordinate of the headlight 5. Document 2 also states that the Z-axis limited clearance and surface difference of the front bumper 4 can well match the headlight without causing the risk of damage such as water leakage or light leakage to the headlight 5 itself. Given that the front bumper 4 and the headlights 5 in Document 2 are respectively connected to the front-end module 3, the front bumper 4 and the headlights 5 are not directly related but indirectly related, and the gap and face difference between the two are determined by the cumulative errors of assembling the front bumper 4 and the headlights 5 with the front-end module 3 respectively. Therefore, it is extremely difficult to control the gap and face difference between the front bumper 4 and the headlights 5, and as the vehicle continues to be used, the gap and face difference between the front bumper 4 and the headlights 5 will significantly deteriorate. Summary of the Invention

[0005] The purpose of the present invention is to provide a connection structure between a headlight and an air intake grille, so as to improve the gap and surface difference quality at the adjacent parts of the headlight and the air intake grille.

[0006] To achieve the above-mentioned purpose, the present invention adopts the following technical solution: a connection structure between a headlight and an air intake grille, characterized in that: a connecting bracket is provided at the lower inner end of the lamp housing of the headlight, a rearward extending protrusion is provided at the back end of the air intake grille, the connecting bracket extends to the bottom of the protrusion and the two form a limiting fit in the X, Y and Z directions.

[0007] The core of the above solution is to directly link the headlights and the air intake grille together, implement positioning connection at the adjacent parts of the two, and realize limit coordination in the X, Y, and Z directions to ensure the quality of the gap and surface difference in the adjacent parts of the headlights and the air intake grille.

[0011] Figure 7 、 8 They are respectively schematic diagrams of the three-dimensional structure of the invention. DETAILED DESCRIPTION

[0012] In view of the relationship between spatial positions, it is first necessary to explain the meaning of the relevant directions. When observing the vehicle facing the front, the surface of the air intake grille 2 observed is the exterior surface, that is, the front, and the surface of the air intake grille 2 facing the cabin is the back; the front direction of the vehicle is the front, and the rear direction is the back; the headlights 1 usually extend in the width direction of the vehicle, and the end of the headlight 1 close to the side where the air intake grille 2 is located is the inner end, and the end close to the side where the fender is located is naturally the outer end; for the air intake grille 2, its enclosed area is a horizontally placed square or elliptical area, and the upper edges of the left and right ends are adjacent to the lower edges of the inner ends of the left and right headlights 1, and the end of the air intake grille 2 refers to the left or right end.

[0013] The present invention provides a connection structure between a headlight and an air intake grille. The accompanying drawings show the assembly structure of a left headlight, which refers to the left headlight when viewed from inside the passenger compartment.

[0014] A connecting bracket 10 is provided at the lower inner portion of the lamp housing of the headlight 1, and a rearward extending boss 20 is provided at the back end of the air intake grille 2. The connecting bracket 10 extends to the bottom of the boss 20 and the two form a limiting fit in the X, Y, and Z directions.

[0015] Combine Figure 7 、 8 The above scheme is to directly associate the headlamp 1 and the air intake grille 2, where the quality of the fitting gap and surface difference needs to be controlled. The specific scheme is to set a connecting bracket 10 at the lower inner end of the lamp shell of the headlamp 1, so that the connecting bracket 10 and the rearward extending protrusion 20 set at the back end of the air intake grille 2 extend toward each other and form a contact-type positioning and limiting fit, thereby controlling and limiting the X, Y, and Z directions between the two, and naturally ensuring the quality of the gap and surface difference at the fitting point between the headlamp 1 and the air intake grille 2.

[0016] Preferably, the connecting bracket 10 has a support 11 with a plate facing upward, and the boss 20 has a base 21 with a plate facing downward. The support 11 is supported on the base 21, and the two form a limit fit that restricts the upward displacement of the support 11 relative to the base 21 or the downward displacement of the base 21 relative to the support 11. The selection of a fit with the support 11 at the bottom and the boss 20 at the top mainly limits the Z-direction position between the two, which may cause the headlight 1 shell to be subjected to a plumb load, which is also a concern of Document 2. The present invention utilizes the characteristic that the volume of the headlight 1 shell occupies the interior space of the cabin, that is, the characteristic that the headlight 1 shell extends into the cabin, which is conducive to providing a suitable support point for the support 11. On the contrary, the air intake grille 2 is entirely externally located in front of components such as the water tank. There are no suitable components or parts on the existing vehicle frame for the boss 20 to provide support. Otherwise, additional support points can only be provided, which will inevitably increase the number of accessories and is not conducive to the lightweight requirements of the vehicle.

[0017] The Z-axis position between the support 11 and the protruding seat 20 primarily controls the surface difference between the headlight 1 and the air intake grille 2. Furthermore, the size and uniformity of the gap between the adjacent edge contours of the headlight 1 and the air intake grille 2 must be controlled. To this end, the present invention employs a solution in which the support 11 and the base 21 are provided with vertically interlocking concave and convex portions that constrain the position of the two components in the X and Y axes. The interlocking of the vertically interlocking concave and convex portions naturally constrains the positional relationship between the two components in the X and Y axes.

[0018] Preferred as Figure 1 、 2 3, the headlight 1 shown is the left headlight and the light-transmitting glass and the lamp have been hidden, and the headlight 1 only shows the headlight housing, and Figure 1 The observer is located in the front left side of the vehicle to observe; Figure 2 The observer is located slightly to the right of the rear of the headlight and is looking upwards; Figure 3 The observer is standing in front of the right side of the headlight for observation.

[0019] The support platform 11 is provided with a groove with the notch facing upward or a strip hole 111 that passes through in the up and down directions. The length direction of the groove or the long hole edge of the strip hole 111 is located in the width direction of the vehicle. The seat bottom 21 is provided with a convex strip 211. The length direction of the convex strip 211 is consistent with the length direction of the groove or the long hole edge of the strip hole 111.

[0020] More preferably, the profile of the strip hole 111 is rectangular, the cross-section of the ridge 211 is triangular, the length of the ridge 211 is consistent with the length of the long side of the strip hole 111, and the roots of the front and / or rear sides of the ridge 211 abut against the front and / or rear walls of the strip hole 111. The cooperation between the strip hole 111 and the ridge 211 in the vehicle length direction, i.e., the X-direction, limits their relative positions in the X-direction. When the roots of the front and rear sides of the ridge 211 simultaneously abut against the front and rear walls of the strip hole 111, bidirectional X-direction limitation is achieved.

[0021] The support platform 11 is a slanted surface with a low front end and a high rear end, and the base 21 is a slanted surface with a high rear end and a low front end. The slanted arrangement of the support platform 11 and the base 21 facilitates the adaptation and installation of the two, and is also conducive to the introduction of the triangular cross-section rib 211 into the bar hole 111.

[0022] See also Figure 1 、 2 3. A connecting plate 12 is provided on the connecting bracket 10. The connecting plate 12 is located at the lower inner side of the support platform 11. The connecting plate 12 is detachably connected to the water tank rack 3. The water tank rack 3 is a vehicle body strength component. By utilizing its reliable strength and rigidity and taking advantage of its proximity, the connecting bracket 10 is fixed to the side column of the water tank rack 3 without affecting the installation and fixation of the water tank. The connection and support problem of the connecting plate 12 is solved. The connecting plate 12 is arranged at the lower inner side of the support platform 11, that is, close to one side of the water tank rack 3 and biased below the support platform 11, realizing a bottom-up supporting effect and having both vehicle width and vehicle length directions, i.e., Y and X direction limitation. During specific installation, a bracket 3a is connected to the outer side of the column of the water tank rack 3, and the horizontal supporting surface of the bracket 3a is supported below the connecting plate 12.

[0023] In view of the need for styling, the grille area of ​​the air intake grille 2 is set to be larger, which is a popular styling trend at present. It is jokingly called the big mouth design. In the present invention, a grille baffle 23 is provided at the back end of the air intake grille 2. The front end of the protrusion 20 is integrally connected to the upper part of the back of the grille baffle 23. Figure 5 、 6As shown, it is relatively easy to directly integrally form the boss 20 on the grille baffle 23, while reducing the difficulty of forming the air intake grille 2. In addition, the grille baffles 23 are placed at the left and right ends of the back of the air intake grille 2, which does not affect the design of the front of the air intake grille 2. The grille baffles 23 can also be used to block the range of the air intake area on the left and right ends of the air intake grille 2, ensuring that the front of the water tank is exposed to wind and preventing cold air from flowing around the left and right sides of the water tank and reducing the cooling effect of the water tank. Figure 5 、 6 As shown, a connecting ear seat 231 is provided at the edge of the grille baffle 23, and a connecting hole 232 is provided on the connecting ear seat 231 to facilitate connection with the back of the air intake grille 2. The addition of the grille baffle 23 also enhances the deformation resistance of the air intake grille 2.

[0024] Preferably, an elastic pad 22 is attached to the rear end of the convex seat 20. The cooperation between the support platform 11 and the base 21 is a contact cooperation. In order to reduce the wear and abnormal noise caused by the sliding friction between the two, the elastic pad 22 on the convex seat 20 plays the role of an elastic pre-tightened cushion.

[0025] In order to ensure the reliability of the connection between the support 11 and the housing of the headlight 1, the present invention provides an optimized design scheme between the support 11, the connecting plate 12 and the housing of the headlight 1, such as Figure 1 、 2 As shown in Figures 3 and 4, the connecting plate 12 is flat, with vertical connecting ribs 13 between the edge of the connecting plate 12 and the adjacent side surface of the support platform 11. The edge of the connecting plate 12 near the radiator frame 3 has vertical reinforcing ribs 14. A hanging frame 15 connects the connecting plate 12 and the support platform 11 to the lower inner end of the lamp housing of the headlight 1 from bottom to top. The overall plate-and-frame structure formed by the support platform 11, connecting plate 12, connecting ribs 13, reinforcing ribs 14, and hanging frame 15 not only solves the connection strength problem but also solves the problem of lightweight design of the components, and also solves the spatial positioning problem of the support platform 11 and connecting plate 12.
