Description

Technical Field

[0001] This invention relates to automobile air intake grilles, and more specifically to a new structure and manufacturing method of automobile air intake grilles. Background Technology

[0002] With technological advancements and the diversification of people's needs for vehicles, car grilles not only need to fulfill the basic function of providing airflow and cooling for the engine compartment, but also, due to their unique placement, require aesthetic design to enhance their recognizability.

[0003] The technical solution disclosed in the document entitled "Automotive Air Intake Grille Structure" (document number CN 210822138 U) aims to reduce the difficulty of component injection molding and back panel painting, and improve structural strength, rigidity and visual effect. The design includes a painted back panel 1 with an opening in the middle, an electroplated outer frame trim 2 installed circumferentially on the front of the painted back panel 1, and a number of mounting feet spaced circumferentially on the back of the electroplated outer frame trim 2. The painted back panel 1 has corresponding mounting grooves, and the mounting feet are inserted into the mounting grooves and connected to the painted back panel 1 by fastening screws. A mesh electroplated grille 3 is installed in the opening in the middle of the painted back panel 1 by welding. The mesh electroplated grille 3 is a centrally protruding structure that is installed on the painted back panel 1 and protrudes forward from the opening. The three components in this document, which are independently injection molded and assembled together, do reduce the processing difficulty of the grille. That is, the electroplated outer frame trim 2 and the mesh electroplated grille 3 can be independently electroplated for decorative treatment. However, the decorative visual effects of the painted back panel 1, the electroplated outer frame trim 2, and the mesh electroplated grille 3 are still independent areas. In other words, the decorative area of ​​the mesh electroplated grille 3 is only in the opening area in the middle of the painted back panel 1. The mesh electroplated grille 3 does not achieve interactive decorative effect support and enhancement with the painted area on the painted back panel 1 outside the opening area in the middle of the painted back panel 1. Similarly, the electroplated outer frame trim 2 only decorates its own frame outline and does not penetrate into the area of ​​the mesh electroplated grille 3 to reflect the mesh electroplated grille 3 unit to improve the decorative effect, nor does it assist in enhancing the painted effect on the painted back panel 1.

[0004] The utility model document entitled "An Air Intake Grille with Decorative Strips" (Document No. CN216069900U) discloses a grille body (1) comprising multiple spaced grille bars (11). A decorative strip (2) can be detachably and fixedly connected to the front of any of the grille bars (11), allowing the user to obtain a decorative strip (2) of their preferred color through removal and replacement. Its visual effect is solely provided by the decorative strip (2), and despite its complex structure, it fails to offer a rich and varied visual experience.

[0005] The document titled "A High-Strength Automotive Air Intake Grille" (CN209776369U) describes a grille with a wave-shaped reinforcing strip between the top of the grille body and the decorative strip. A sealing wave strip on the upper part of the sealing plate effectively absorbs the lateral pressure on the automotive air intake grille, preventing deformation even from minor impacts. The cooperation between the sealing plate and the first grille area absorbs the longitudinal pressure on the grille, and the cooperation between the second grille area and the first grille area further enhances its ability to absorb longitudinal pressure. It is evident that this document focuses on improving the structural strength of the air intake grille, neglecting its three-dimensional and dynamic visual appeal. Summary of the Invention

[0006] The purpose of this invention is to provide an air intake grille assembly and its manufacturing method. The grille units constituting the grille assembly have a variety of brightness and color, with at least two options, thereby improving the three-dimensional and dynamic visual effect of the grille.

[0007] To achieve the above-mentioned objectives, the present invention discloses the following technical solution: an air intake grille assembly, characterized in that: the grille body has a body frame, and body grille bars are staggered within the frame area of ​​the body frame, the body grille bars are arranged in a matrix-like arrangement of grille hole area units, the interior grille is connected to the grille body from the back of the grille body, the interior grille includes staggered interior grille bars, the interior grille bars are arranged in a matrix-like arrangement of interior grille hole area units, a trim panel unit is provided within the interior grille hole area unit, the trim panel unit is filled within the grille unit hole area and the area of ​​the trim panel unit is smaller than that of the grille hole area unit, the front face of the trim panel unit is offset from and / or angled to the front face of the body grille bar of the grille hole area unit in which it is placed.

[0008] The preparation method includes the following steps:

[0009] Step 1: Molding the grille body and interior grille;

[0010] Step 2: Select the paint color and apply paint to both the grille body and the interior grille.

[0011] Step 3: Position the grille body and the interior grille together and then weld them together.

[0012] In the above solution, the grille body and the interior grille are connected to each other. The two independent components can be pre-painted with different reflective properties and colors, so that the grille body and the trim unit have different paint surfaces. At the same time, the grille body and the trim unit can be set as a glossy surface that is conducive to reflecting light or a frosted surface that diffuses light. The resulting air intake grille assembly has colorful glossy forms and diverse visual effects, enhancing the three-dimensional and dynamic effect of the grille. Attached Figure Description

[0026] Example 1

[0027] like Figures 1-7 As shown, an air intake grille assembly includes a grille body 10 with a body frame 10A. Body grille bars 11 are staggered within the frame of the body frame 10A, forming a matrix of grille aperture units 12. An interior grille 20 is connected to the grille body 10 from its back. The interior grille 20 includes staggered interior grille bars 21, which form a matrix of interior grille aperture units 22. A trim panel unit 23 is disposed within the interior grille aperture units 22. The trim panel unit 23 is placed within the grille unit aperture units 12, and its area is smaller than the area of ​​the grille aperture units 12. The front face of the trim panel unit 23 is staggered and / or angled with the front face of the body grille bars 11 of the grille aperture unit 12.

[0028] In the above scheme, the trim unit 23 on the interior grille 20 can be painted with a color selected by the user. Furthermore, since the trim unit 23 is placed within the corresponding grille aperture unit 12 and positioned slightly behind the front surface of the main grille bar 11, the two work together to create a significant three-dimensional effect. Simultaneously, because the front surface of the trim unit 23 is arranged at an angle to the front surface of the main grille bar 11 of the grille aperture unit 12, the trim unit 23 can receive and reflect light from different directions. Moreover, when the light source is fixed but the viewing angle changes, it can obtain reflected light that moves with the light, further enhancing the three-dimensional effect and strengthening the dynamic feel. Additionally, since the trim unit 23 is equivalent to... The recessed design is located inside the front surface of the main grille bar 11, and the edge of the trim unit 23 is darker, which reduces the amount of work required to repair defects in the injection molding and painting of the trim unit 23. Even if there are some injection molding and painting defects on the edge of the trim unit 23, they are difficult to observe. Furthermore, since the front surface of the main grille bar 11 can achieve excellent appearance quality during injection molding and painting, the processing cost of the product can be significantly reduced. In addition, the present invention provides a double grille structure that connects the grille body 10 and the interior grille 20, which can naturally ensure the stability and strength of the grille assembly, prevent vibration and abnormal noise during normal driving, and have the ability to resist minor collisions.

[0029] Preferred solutions include Figure 7 , 8 As shown in Figures 9 and 10, the interior grille 20 includes an interior grille frame 20A whose position corresponds to the body frame 10A. Interior grille bars 21 are staggered within the frame area of ​​the interior grille frame 20A. The area of ​​the trim panel unit 23 is smaller than the area of ​​the hole area of ​​the interior grille hole area unit 22 to which it is placed. The outlines of the interior grille hole area unit 22 and the grille hole area unit 12 match each other. The partial outline edge of the trim panel unit 23 is aligned with the partial edge of the body grille bar 11 of the grille hole area unit 12 to which it is placed.

[0030] To ensure that the structure of the grille body 10 facilitates melt flow during injection molding, it is essential to avoid excessive differences in the volume of the molding cavity between the body frame 10A and the body grille rod 11. This ensures that the melt can fill all parts of the cavity. Furthermore, significant abrupt changes in thickness at transition points can easily lead to surface wrinkling and stress concentration defects. Therefore, the thickness of the body frame 10A needs to be appropriate and should not be too thick, which in turn limits its strength. The interior grille 20 is fitted with an interior grille frame 20A, which connects to the body frame 10A. This not only helps to enhance the strength of the body frame 10A but also ensures the integrity of the interior grille 20 and the molding process, while improving assembly efficiency. This eliminates the need to make the trim unit 23 an independent unit, instead creating a continuous structural form. Since the area of ​​the trim panel unit 23 is smaller than the area of ​​the grille hole area unit 12 in which it is placed, this provides a passage for airflow to enter the cabin. It also highlights the trim panel unit 23 as an independent unit, giving it a dynamic visual effect, rather than a large area of ​​the same color panel that gives people a sense of oppression and dullness. Since the partial outline edge of the trim panel unit 23 is close to the partial edge of the main grille bar 11 of the grille hole area unit 12 in which it is placed, the main grille bar 11 can be used to cover the edge of the trim panel unit 23 to reduce the processing defects caused by the injection molding and painting processes that are prone to occur at the edge, and it is also conducive to the reliable fixation of the trim panel unit 23.

[0031] The structural relationship between the decorative panel unit 23 and the main grille bar 11 provided by this invention can achieve rich visual effects. Specifically, the front of the decorative panel unit 23 and the main grille bar 11 are coated with paints of different reflective properties and / or shades. For example, the main grille bar 11 can be painted with glossy black paint, while the decorative panel unit 23 is painted with a diffuse matte silver or light gray. Against the backdrop of the matte silver or light gray provided by the decorative panel unit 23, the fine mesh-like bright lines provided by the main grille bar 11 appear more delicate, possessing a striking sense of layering without being glaring or oppressive, thus avoiding the commonly used wide, bright band finishes in the prior art.

[0032] like Figures 1-6 As shown, the main body grille bar 11 includes a lateral grille bar 10A and a lateral grille bar 10B. The lateral grille bars 10A and the lateral grille bars 10B are arranged alternately to form a matrix-distributed grille hole area unit 12. The periphery of the grille hole area unit 12 is rhomboid and the four corners are located at the top, bottom, left, and right positions. The outline of the trim panel unit 23 is triangular and the apex corner 231 of the trim panel is arranged downward at the corner position of the lower part of the grille unit hole area 12. The top edge 232 of the trim panel unit 23 is horizontally placed in the middle of the grille unit hole area 12.

[0033] Existing technologies have various forms of grille perforation, such as the vertical strip area formed by two spaced-apart grilles (nicknamed "waterfall grille"), the square perforation formed by staggered grilles, and horizontal trim strips. The key point of the rhomboid shape of the grille perforation unit 12 selected in this invention is that the apex 231 of the triangular trim panel unit 23 is positioned downwards at the lower corner of the grille perforation unit 12. An air intake passage is reserved above the top edge 232 of the trim panel to contribute cooling airflow to the engine compartment. The trim panel unit 23 is arranged in the lower half of the rhomboid area of ​​the grille perforation unit 12, enhancing the dynamic visual effect of the trim panel unit 23. Furthermore, the airflow reaching the grille perforation unit 12 flows backwards and upwards simultaneously, which helps reduce wind resistance and guides airflow into the engine compartment.

[0034] like Figure 1 , 1a As shown, a decorative bead 30 is provided in the middle of the top edge 232 of the decorative panel unit 23. Since the upper part of the top edge 232 of the decorative panel is a dark part that leads directly to the engine compartment, the decorative bead 30 provided here can play a finishing touch role. Furthermore, the lower part of the decorative bead 30 is supported by the surface of the decorative panel unit 23, and the two complement each other. In order to enhance the decorativeness of the decorative bead 30, the outer surface of the decorative bead 30 can be selected as a diamond-shaped multifaceted shape.

[0035] As shown in the figure, the trim panel unit 23 has a forward-protruding tubular or platform-shaped fixing seat 24 at the middle of the top edge 231 of the trim panel, and the trim beads 30 are arranged on the fixing seat 24. This can reliably fix the trim beads 30. In addition, the fixing seat 24 is located at the middle of the top edge 232 of the trim panel, which can strengthen the rigidity of the free edge and prevent it from vibrating and generating noise when the vehicle is in motion.

[0036] As a preferred embodiment, the trim area of ​​the trim unit 23 has a slightly curved, forward-convex shape. The top corner 231 of the trim is positioned forward, and the top edge 232 is positioned rearward. The left and right ends of the top edge 232 are staggered. The trim of the trim unit 23 provided by this embodiment can provide flowing light and shadow changes when the vehicle is in motion. The grille assembly can exhibit a strong three-dimensional effect when the vehicle is in motion or stationary. Furthermore, the arrangement of the top corner 231 being forward, the top edge 232 being rearward, and the left and right ends of the top edge 232 being staggered also ensures low airflow resistance when entering the engine compartment.

[0037] Combination Figure 4 , 5As shown in Figure 6, the back of the four sides of the grille hole unit 12 at the upper left, upper right, lower right, and lower left positions have upper left, upper right, lower right, and lower left enclosure walls 13a, 13b, 13c, and 13d, respectively. The walls of the upper left, upper right, lower right, and lower left enclosure walls 13a, 13b, 13c, and 13d are aligned with the glancing grille bar 11A and the pressing grille bar 11B, respectively. The lower right enclosure wall 13c on both sides of the same glancing grille bar 11A and the upper left enclosure wall 13a are spaced to form a glancing slot 14A. The upper right enclosure wall 13b on both sides of the same pressing grille bar 11B and the lower left enclosure wall 13d are spaced to form a glancing slot 14B. The interior grille bar 21 on the interior grille 20 is inserted into the aforementioned glancing slot 14A and pressing slot 14B.

[0038] In the above scheme, the glancing slots 14A and 14B are not slots with continuous walls, but rather each grid hole area unit 12 has a section of wall, which is arranged in a discontinuous, continuous manner. Furthermore, the lower right wall 13c and upper left wall 13a on both sides of the same glancing grid rod 11A constituting the glancing slot 14A belong to two adjacent grid hole area units 12. Moreover, the glancing grid rods 11A and 11B should not be simply understood as rods with square or circular cross-sections. In fact, in this invention, the cross-section of the joint between the glancing grid rod 11A, the lower right wall 13c, and the upper left wall 13a is a widened U-shape or a small-angled V-shape. Therefore, part of the glancing grid rod 11A is actually the bottom of the slot. Figure 5a , 6a As shown, at the intersection of the grid bar 11A and the grid bar 11B, the upper left and lower left walls 13a and 13d of the same grid hole area unit 12 are arranged in an angular plate shape. The upper right and lower right walls 13b and 13c of the adjacent right grid hole area unit 12 are also angular plates. The openings of the two angular plates are opposite to each other and the corners are arranged opposite each other.

[0039] As a preferred embodiment, the upper left and upper right enclosures 13a and 13b have the same edge contour, and the lower right and lower left enclosures 13c and 13d have the same edge contour, with their edges adhering to the left and right edges of the panel unit 23. Figure 11 As shown, since the inner edges of the lower right and lower left enclosures 13c and 13d press against the two side edges of the trim unit 23, it ensures that the trim surface of the trim unit 23 is recessed within the area enclosed by the grille bar 11A and the grille bar 11B to enhance the three-dimensional effect, while also concealing the processing defects on the trim edge of the trim unit 23 that do not require trimming.

[0040] Correspondingly, the interior grille bar 21 is not a continuous bar. Due to the inclusion of the trim panel unit 23, the left and right sides of the triangle formed by the trim panel unit 23 create a continuous connecting part. This not only saves materials and simplifies the structure but also improves strength. A specific implementation scheme is as follows: Figure 7 , 8 As shown in Figures 9 and 10, the trim panel unit 23 has left and right support walls 23A and 23B on its back side, which are connected to the interior grille rod 21. The upper edge of the back side of the trim panel unit 23 has an upper support wall 23C extending towards the back. The left and right ends of the upper support wall 23C are connected to the interior grille rod 21. The upper support wall 23C also improves the stability of the fixing seat 24. The arrangement of the left and right support walls 23A and 23B and the upper support wall 23C solves the stability problem of the thin-walled trim panel unit 23, while also serving as connecting components for the unit area.

[0041] Insertion holes 25 are provided at the left or right edge of the trim panel unit 23, and tongues 15 are provided on the grille body 10 facing the grille bar 11A or facing the grille bar 11B. Figure 4a , 5a As shown in Figure 6a, the tongue 15 is inserted into the socket 25 and welded to the back side, thus forming a connection. Figure 8a , 9a 10a. This not only achieves a fixed connection between the two, but also ensures that the inner edges of the lower right and lower left enclosures 13c and 13d press against the two side edges of the trim unit 23, while simultaneously concealing the connection between the tongue 15 and the insertion hole 25, resulting in a flush and flawless appearance. To ensure assembly accuracy, the position of the tongue 15 inserted into the insertion hole 25 is basically fixed during initial assembly for subsequent welding and fixing. A positioning fit is also provided between the grille body 10 and the trim unit 23, namely, positioning anti-return claws 16 are provided on the grille body 10 facing the grille rod 11A or facing the grille rod 11B, such as... Figure 5a , 6a As shown, the positioning anti-return claw 16 is disposed on the grille bar 11A and located between the upper left wall 13a of one grille hole area unit 12 and the lower right wall 13c of the adjacent grille hole area unit 12. The edge side of the trim panel unit 23 has a corresponding clearance portion for the insertion of the positioning anti-return claw 16 and an anti-return portion 26 that cooperates with the claw of the positioning anti-return claw 16 to restrict separation from each other. Figure 8a , 10a As shown.

[0042] Example 2

[0043] The method for manufacturing the air intake grille assembly provided in Example 1 includes the following steps:

[0044] Step 1: Form the grille body 10 and the interior grille 20;

[0045] Step 2: Select the paint color and apply paint to the grille body 10 and the interior grille 20 respectively;

[0046] Step 3: The grille body 10 is snapped into place with the interior grille 20 and then welded.

[0047] In step 3 above, the selected welding location is a plug hole 25 provided at the left or right edge of the decorative panel unit 23. A tongue 15 is provided on the lateral grille bar 11A or lateral grille bar 11B that constitutes the grille body 10. The tongue 15 is inserted into the plug hole 25 and welded on the back side.

[0048] The manufacturing method provided by this invention employs a snap-fit ​​positioning and welding at the insertion mating parts, achieving a reliable connection between the two components. Specifically, by selecting insertion holes 25 at the left or right edge of the trim panel unit 23 and inserting them into the grille bar 11A or grille bar 11B with tongues 15, welding is performed, solving the stability problem of fixing the trim panel unit 23, which is an important decorative element. Both the welding points of the insertion holes 25 and tongues 15, and the mating points of the positioning check claws 16 and check parts 26, are located on the back or in obscured positions. This prevents damage to the exterior surfaces of the grille body 10 and the interior grille 20 during assembly, ensuring the aesthetic appeal of the air intake grille assembly and significantly reducing the workload of repairing defects during assembly.
