Description

Technical Field

[0001] This application relates to the field of vehicle parts technology, and more particularly to a decorative panel, a dashboard air vent module, and a vehicle. Background Technology

[0002] In automotive interior design, to enhance visual appeal and meet personalized needs, the trim panels around the air vents of the dashboard often require a segmented visual effect, such as displaying different colors, patterns, or textures in different areas. Achieving this segmented visual effect typically involves assembling multiple independently manufactured components. For each segment with different visual characteristics (such as color or texture), a dedicated injection mold must be designed and manufactured. These different molds are then used to injection mold multiple independent components corresponding to different visual effects. These components are then assembled to form a complete trim panel with the desired multi-segmented visual effect.

[0003] However, the complex structure of interconnected components, the cumbersome assembly process, and the need to design and develop multiple molds all affect the manufacturing efficiency of decorative panels and increase their manufacturing costs. Utility Model Content

[0004] In order to solve the above-mentioned technical problems, or at least partially solve the above-mentioned technical problems, this application provides a decorative panel, a dashboard air vent module, and a vehicle.

[0005] The first aspect of this application provides a decorative panel, which is an integral injection molded part. The decorative panel has at least two films with different visual effects integrated on it, and a separation structure is formed on the outer surface of the decorative panel at the boundary between two adjacent films. The separation structure makes the two adjacent films present a matching visual effect.

[0006] The decorative panel provided in this application is an integral injection-molded part. The decorative panel integrates at least two films with different visual effects, and a separating structure is formed at the boundary between adjacent films on the surface of the decorative panel. This separating structure allows the adjacent films to present a matching visual effect. This arrangement creates multiple areas with different visual effects on the surface, and the overall visual effect of the surface is consistent with that of a decorative panel formed by assembling multiple components. This allows the decorative panel provided in this application to replace traditional decorative panels formed by assembling multiple components. During injection molding, the mold has a molding structure corresponding to the separating structure. Multiple films can be pre-positioned through the molding structure, and during injection molding, the separating structure restricts the movement of the films, preventing offset and mutual interference, ensuring that the multiple films on the injection-molded decorative panel are in the required positions. A decorative panel with a zoned visual effect can be formed by injection molding with a single mold, eliminating the need for assembling multiple components to form a panel with a zoned visual effect. This reduces the number of molds required to manufacture the decorative panel, lowers manufacturing costs, simplifies the manufacturing process, and improves manufacturing efficiency.

[0007] In some embodiments of this application, the separating structure includes a slot formed at the boundary between two adjacent membranes, wherein the two adjacent membranes extend obliquely toward each other near each other's edges and abut together to jointly form the slot.

[0008] Based on the above embodiments, the seam groove can divide the exterior surface into multiple areas. During injection molding, the mold and the position corresponding to the seam groove will be provided with ribs. The ribs can initially position adjacent films and also limit the displacement of adjacent films. The seam groove formed on the exterior surface separates two adjacent films, making the seam groove a transition structure between two films, avoiding the edges of adjacent films from touching or overlapping, which would create a visual sense of discontinuity. The seam groove visually resembles the seam of traditional trim panels, making the appearance of the trim panel similar to that of traditional trim panels, so that the replacement of traditional trim panels with trim panels will not affect the visual matching of the vehicle interior.

[0009] In some embodiments of this application, the boundary between two adjacent membranes is used as the dividing line. The area of ​​the decorative panel corresponding to one of the membranes protrudes from the area of ​​the decorative panel corresponding to the other membrane along the thickness direction of the decorative panel, so that a stepped separation structure is formed at the boundary between two adjacent membranes.

[0010] Based on the above embodiments, the stepped partition structure has a height difference between the areas on both sides, giving the exterior a layered visual effect. The stepped structure also restricts the position of the diaphragm. The visual effect of the stepped partition structure is similar to that of multiple components with height differences in traditional trim panels, allowing the trim panels to match the vehicle interior after replacing traditional trim panels.

[0011] A second aspect of this application provides an instrument panel air vent module, including a panel and a decorative panel as described above, the decorative panel being mounted on the panel.

[0012] The dashboard air vent module provided in this application uses the decorative panel described above, which allows the decorative panel to cover the housing and has a partitioned visual effect, avoiding the use of multi-part spliced ​​decorative panels and reducing the manufacturing cost of the dashboard air vent module.

[0013] In some embodiments of this application, the top of the panel is provided with an upright welding plate, and an arc-shaped segment extending along the top surface of the panel is formed on the welding plate. The decorative panel is provided with a rib corresponding to the welding plate on the side facing away from the exterior surface, and the rib is welded and fused together with the welding plate.

[0014] Based on the above embodiments, the welded plate with the arc segment has a stable structure and is not easily tilted when under pressure after heating, ensuring the welding quality between the welded plate and the stiffener. The decorative panel can be placed on the panel for the fusion welding operation between the stiffener and the welded plate, facilitating automated batch welding for efficient production of decorative panels.

[0015] In some embodiments of this application, a plurality of arc-shaped segments are sequentially formed on the welding plate along the extension direction of the welding plate, and two adjacent arc-shaped segments protrude in opposite directions, and the stiffener is welded to the plurality of arc-shaped segments.

[0016] Based on the above embodiments, multiple arc segments provide support structures for the welding plate in two opposite directions, and multiple arc segments can have multiple welding points with the stiffener, thereby improving the stability of the welding connection between the welding plate and the stiffener.

[0017] In some embodiments of this application, the number of welding plates is multiple, and at least two of the welding plates are arranged in staggered directions;

[0018] There are multiple stiffening plates, and each stiffening plate is welded to a corresponding welding plate. The extension direction of each stiffening plate is parallel to the extension direction of the corresponding welding plate.

[0019] Based on the above embodiments, multiple welding plates are welded to multiple stiffening plates, so that the connection points between the decorative panel and the panel are evenly distributed, thereby improving the stability of the welded connection between the decorative panel and the panel; and welding plates and stiffening plates arranged in different directions are welded to each other, so that the welding plates provide multi-directional support to the decorative panel, thereby improving the stability of the connection between the decorative panel and the panel.

[0020] In some embodiments of this application, the top of the panel is provided with a plurality of positioning holes, and the side of the decorative panel facing away from the exterior surface is provided with a plurality of positioning members, and the plurality of positioning members are connected to the plurality of positioning holes in a one-to-one manner.

[0021] Based on the above embodiments, multiple positioning components are inserted into multiple positioning holes to guide the decorative panel to be positioned on the top side of the panel. Furthermore, when the decorative panel is welded to the panel, it can limit the offset between the decorative panel and the panel, making it convenient for the decorative panel to be installed on the panel.

[0022] In some embodiments of this application, the panel is provided with weight-reducing holes, which are offset from the welding plate.

[0023] Based on the above embodiments, the weight reduction holes reduce the weight of the welding plate, thereby reducing the overall weight of the instrument panel air vent module.

[0024] A third aspect of this application provides a vehicle including an instrument panel vent module as described in any of the preceding claims.

[0025] The vehicle provided in this application embodiment uses the above-mentioned dashboard air vent module. The decorative panel has a simple structure and low manufacturing cost. The decorative panel gives the dashboard air vent module a good visual effect, thereby reducing vehicle manufacturing costs and improving the aesthetics of the vehicle interior.

[0037] To better understand the above-mentioned objectives, features, and advantages of this application, the solution of this application will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0038] Many specific details are set forth in the following description in order to provide a full understanding of this application, but this application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of this application, and not all embodiments.

[0039] The existing dashboard air vents have a relatively complex structure, requiring decorative panels to conceal the vent housings and other structural elements to enhance the aesthetics of the vehicle interior. For visual appeal and to meet individual needs, automotive interiors require decorative panels to present a segmented visual effect, ensuring the panels complement the overall interior design. However, existing decorative panels typically consist of multiple injection-molded components, each using different materials and colors to create distinct visual effects. While assembling these components can achieve a segmented visual effect, the cost of creating individual injection molds and using different materials for each component is high, and the complex assembly of multiple components reduces production efficiency.

[0040] And reference Figures 1 to 8As shown, the first aspect of this application provides a decorative panel. The decorative panel 1 is an integral injection molded part. At least two films 13 with different visual effects are integrally integrated on the decorative panel. A separation structure 12 is formed on the outer surface 11 of the decorative panel 1 at the boundary between two adjacent films 13. The separation structure 12 makes the two adjacent films 13 present a visual effect of being matched and aligned.

[0041] Multiple membranes 13 are exposed on the surface 11, making the surface 11 divided into multiple sections with different visual effects. The partition structure 12 separates two adjacent membranes 13 on the surface 11. The visual effect of the surface 11 is consistent with the visual effect of the decorative panel formed by splicing and installing multiple components, so that the decorative panel 1 can replace the decorative panel formed by splicing multiple components.

[0042] It should be noted that in order to form a partition structure 12 on the outer surface 11 of the decorative panel 1, a corresponding structure for forming the partition structure 12 is provided on the inner wall of the mold used for injection molding. Multiple films 13 can be pre-positioned through the corresponding structure. The partition structure 12 formed during the injection molding process can also restrict the position of the films 13, ensuring that the multiple films 13 on the injection-molded decorative panel 1 are in the required position.

[0043] As a single component, the decorative panel 1 can achieve a partitioned visual effect by using multiple films 13 and partition structures 12. The decorative panel 1 with partitioned visual effect can be manufactured with a single mold, which reduces the number of molds required to manufacture the decorative panel 1, reduces the cost of manufacturing the decorative panel 1, and eliminates the need to assemble multiple components to manufacture the decorative panel 1, thus simplifying the manufacturing process and improving the manufacturing efficiency of the decorative panel 1.

[0044] Specifically, decorative panel 1 is injection molded into a mold. Decorative panel 1 is an integrated structure, eliminating the need for multiple parts to be assembled. The outer surface 11 is the top surface of decorative panel 1. When decorative panel 1 is installed on the air vent of the dashboard, the outer surface 11 is exposed on the dashboard, allowing decorative panel 1 to cover the shell structure of the air vent of the dashboard. Furthermore, users can directly observe areas with different visual effects on the outer surface 11 from inside the vehicle. The integrated structure of decorative panel 1 eliminates the need for connecting structures for assembling multiple parts, which helps to reduce the overall volume of decorative panel 1, saves structural space, and also reduces the number of molds required, thus reducing R&D investment costs.

[0045] The aforementioned surface 11 can be a plane or a curved surface; the partition structure 12 can be a groove or a raised step on the surface 11, creating a height difference between the partition structure 12 and the surface 11, thereby dividing the surface 11 into multiple regions. Alternatively, the partition structure 12 can be a continuous groove or step, with both ends extending to the two edges of the surface 11, thus dividing the surface 11 into two regions.

[0046] The aforementioned partition structure 12 and decorative panel 1 are an integrated structure. A groove can be provided on the inner wall of the mold. When the decorative panel 1 is formed by injection molding in the mold, a raised edge is formed on the outer surface 11 corresponding to the groove. The edge extends on the outer surface 11, dividing it into multiple areas, each area corresponding to a diaphragm 13. Adjacent diaphragms 13 are located on either side of the groove, preventing direct contact and interference between the edges of adjacent diaphragms 13. The groove on the inner wall of the mold can pre-position multiple diaphragms 13. During injection molding, the edge formed on the outer surface 11 also restricts the displacement of multiple diaphragms 13 within the mold, preventing positional shifts and interference between adjacent diaphragms 13, ensuring that the multiple diaphragms 13 on the injection-molded decorative panel 1 are in the required positions.

[0047] Alternatively, raised ribs can be provided on the inner wall of the mold. When the decorative panel 1 is formed by injection molding in the mold, grooves will be formed on the outer surface 11 at positions corresponding to the raised ribs. The grooves extend on the outer surface 11, dividing it into multiple areas, each area corresponding to a diaphragm 13. Adjacent diaphragms 13 are positioned on both sides of the edge to prevent direct contact and interference between the edges of adjacent diaphragms 13. The raised ribs on the inner wall of the mold can pre-position the multiple diaphragms 13. During injection molding, the raised ribs on the inner wall can also restrict the displacement of the multiple diaphragms 13 in the mold, preventing positional shifts of the diaphragms 13 and interference between adjacent diaphragms 13, ensuring that the multiple diaphragms 13 on the injection-molded decorative panel 1 are in the required positions.

[0048] Alternatively, a step can be formed by making some areas on the inner wall of the mold higher than others. When the decorative panel 1 is injection molded in the mold, areas with different positions in the thickness direction of the decorative panel 1 will be formed on the outer surface 11. A stepped structure is formed at the junction of the areas with different height positions. The stepped structure acts as a separator 12 to separate two adjacent diaphragms 13, preventing the edges of two adjacent diaphragms 13 from directly contacting each other and interfering with each other. The steps on the inner wall of the mold can pre-position multiple diaphragms 13. During injection molding, the sides of the steps on the inner wall can also restrict the displacement of multiple diaphragms 13 in the mold, preventing the position of the diaphragms 13 from shifting and interfering with adjacent diaphragms 13, ensuring that the multiple diaphragms 13 on the injection-molded decorative panel 1 are in the required positions.

[0049] The aforementioned film 13 is an INS (Insert Molding Sheet). This process involves using thermoforming or high-pressure molding technology to three-dimensionally stretch a pre-transfer-printed INS board, then cutting the insert according to the product's shape, and finally accurately placing the insert into the injection mold cavity to complete the injection molding. INS sheets typically consist of three layers: a bottom base layer, a middle ink and adhesive layer, and an outermost protective layer. The color of the INS sheet can be changed by adjusting the ink color, and the texture of the INS sheet can be adjusted by changing the material and texture of the protective layer, resulting in different films 13 with different visual effects. The multi-layered structure of the INS sheet makes its color and texture effects vivid, durable, and resistant to fading.

[0050] The visual effects of the aforementioned diaphragm 13 include at least one of color, pattern, and texture. Different diaphragms 13 can be selected with different colors, specifically different shades and color schemes. Different diaphragms 13 can also have different patterns; for example, each diaphragm 13 can be a solid wood ring pattern, a solid wood stripe pattern, an array of dotted patterns, an array of circular / rhomboid / regular polygonal patterns, a stripe pattern, or other patterns. Of course, each diaphragm 13 can also be selected as a solid color matte electroplated silver / gold / black, high-gloss electroplated silver / gold / black, or other patternless visual effects. Each diaphragm 13 can also be selected with a deep / shallow three-dimensional tactile texture, a flat non-tactile texture, or other visual effects. The different colors, patterns, and textures of multiple diaphragms 13 allow them to be combined to form a dashboard air vent module with a two-color or multi-color effect.

[0051] The aforementioned film 13 can achieve a solid wood pattern texture effect, a tech-textured pattern effect, or a solid color matte / high-gloss silver, gold, or black effect. Two films 13 installed on two areas of the exterior surface 11 can create a combination of two color effects, allowing the decorative panel 1 to achieve a two-color combination without being split into two parts. Precisely attaching multiple films 13 of different colors, patterns, and textures to corresponding areas allows different areas of the decorative panel 1 to have different visual effects.

[0052] The overall visual effect of the decorative panel 1 can be adjusted by changing the color, pattern, and texture of the film 13, allowing the decorative panel 1 to adapt to various automotive interior color schemes and layouts. Films 13 are correspondingly set on different areas of the exterior surface 11, and multiple films 13 achieve different visual effects in different locations of the decorative panel 1. The films 13 are low-cost to manufacture, and the visual effect of the display area can be changed by using images with different colors, textures, and patterns, thus improving the flexibility of changing the color scheme of the decorative panel 1.

[0053] The decorative panel 1 provided in this application embodiment is an integral injection molded part. At least two films 13 with different visual effects are integrally integrated on the decorative panel. A separating structure 12 is formed at the boundary between two adjacent films 13 on the outer surface 11 of the decorative panel 1. The separating structure 12 makes the two adjacent films 13 appear to be joined together visually. Multiple films 13 and the separating structure 12 cooperate with each other, giving the outer surface 11 multiple areas with different visual effects. Furthermore, the overall visual effect of the outer surface 11 is consistent with the visual effect of a decorative panel formed by splicing multiple components, allowing the decorative panel 1 provided in this application to replace traditional decorative panels formed by splicing multiple components. During injection molding of the decorative panel 1, a molding structure corresponding to the separating structure 12 is provided in the mold. Multiple films 13 can be pre-positioned through the molding structure. During injection molding, the separating structure 12 restricts the movement of the films 13, preventing offset and mutual interference among the multiple films 13, ensuring that the multiple films 13 on the injection-molded decorative panel 1 are in the required positions. A decorative panel 1 with a partitioned visual effect can be formed by injection molding with a single mold, avoiding the need to assemble multiple parts to form a partitioned visual effect. This reduces the number of molds required to manufacture the decorative panel 1, thereby reducing manufacturing costs. Furthermore, it simplifies the manufacturing process of the decorative panel 1 and improves its manufacturing efficiency by eliminating the need to assemble multiple parts.

[0054] Reference Figure 1 and Figures 3 to 6 As shown, in some embodiments, the partition structure 12 includes a slot formed at the boundary of two adjacent membranes 13, which extend at an angle toward each other and abut against each other near each other's edges to jointly form the slot.

[0055] With this design, the seam groove can divide the exterior surface 11 into multiple areas. During injection molding, the mold will have raised ribs at the positions corresponding to the seam groove. The raised ribs can initially position the adjacent films 13 and also limit the displacement of the adjacent films 13. The seam groove formed on the exterior surface 11 separates two adjacent films 13, making the seam groove a transition structure between two films 13, avoiding the edges of adjacent films 13 from touching or overlapping and creating a visual sense of discontinuity. The seam groove visually resembles the splicing seam of traditional trim panels, making the appearance of the trim panel 1 similar to that of traditional trim panels, so that the replacement of traditional trim panels with trim panel 1 will not affect the visual matching of the vehicle interior.

[0056] Specifically, a portion of the outer surface 11 is recessed to form a groove. The cross-section of the groove can be V-shaped, and the connection between the two sidewalls of the groove is an arc-shaped surface to achieve a smooth transition and avoid stress concentration. Alternatively, the cross-section of the groove can be U-shaped, with an arc-shaped transition between the two sidewalls and the bottom of the groove to avoid stress concentration. The groove and the outer surface 11 are smoothly transitioned by a rounded corner with a radius greater than or equal to 1.2 mm.

[0057] The transition between the seam surface and the exterior surface 11 is smooth. If the radius of the rounded corner between the seam surface and the exterior surface 11 is less than 1.2mm, the corner structure formed at the transition point is relatively sharp. The diaphragm 13 is easily damaged when it is applied to the corner, or gaps may easily appear between the corners, affecting the application quality of the diaphragm 13. If the rounded corner between the seam surface and the exterior surface 11 is greater than 1.2mm, the user will have a better feel when touching the decorative panel 1, and stress concentration will be less likely to occur at the connection between the seam surface and the exterior surface 11 when the decorative panel 1 is under stress.

[0058] The mold corresponding to the decorative panel 1 can be provided with a protruding structure. When the decorative panel 1 is formed by injection molding in the mold, the protruding structure can form a groove on the outer surface 11 of the decorative panel 1. When the decorative panel 1 and the diaphragm 13 are integrally injection molded, the protruding structure on the mold can also play the role of positioning multiple diaphragms 13, so that the diaphragms 13 are accurately set in the corresponding area of ​​the outer surface 11.

[0059] The inner wall of the mold corresponding to decorative panel 1 can be provided with raised ribs. The side of the raised ribs transitions smoothly with the curved surface of the inner wall of the mold. The mold is injection molded to form decorative panel 1. The position of decorative panel 1 opposite to the raised ribs is a seam groove. The seam groove and the outer surface 11 are smoothly transitioned. The side wall of the seam groove can be flat, so that the side wall of the seam groove is a straight line on the cross section perpendicular to the extension direction of the seam groove. The straight line dimension of the side wall of the seam groove on the cross section can be selected as 2mm.

[0060] Reference Figure 1 and Figures 2 to 6 As shown, in some embodiments, the area of ​​the decorative panel 1 corresponding to one of the diaphragms 13 is protruding from the area of ​​the decorative panel 1 corresponding to the other diaphragm 13 along the thickness direction of the decorative panel 1, so that a stepped partition structure 12 is formed at the boundary of the two adjacent diaphragms 13.

[0061] With this design, the areas on both sides of the stepped partition structure 12 have a height difference, giving the exterior surface 11 a layered visual effect. The stepped structure also restricts the position of the membrane 13. The visual effect of the stepped partition structure 12 is similar to that of multiple components with height differences in a traditional decorative panel, allowing the decorative panel 1 to match the vehicle interior after replacing the traditional trim panel.

[0062] Specifically, the mold for manufacturing the decorative panel 1 can be partitioned, with some partitions positioned higher than the others, resulting in a stepped structure for the surface 11 of the decorative panel 1 formed by injection molding. The surface 11 can be divided into a first region and a second region. The first region is located on one side of the second region in the thickness direction of the decorative panel 1. A stepped partition structure 12 is formed at the boundary between the first and second regions. A membrane 13 is provided on both the first and second regions. The stepped partition structure 12 separates the two membranes 13 from each other, preventing the edges of adjacent membranes 13 from contacting each other.

[0063] Reference Figures 1 to 8 As shown, a second aspect of the present application provides an instrument panel air vent module, including a panel 2 and a decorative panel as described in any of the preceding claims, wherein the decorative panel 1 is mounted on the panel 2.

[0064] Specifically, panel 2 is a plate structure. A lower panel 3, an upper shell 4, and a lower shell 5 are provided on the bottom side of panel 2 (also called the upper panel). Panel 2 is installed on the top side of the upper shell 4. The upper shell 4 and lower shell 5 are opposite to each other and connected to each other, forming an airflow channel between them. The lower panel 3 is connected to the side of the lower shell 5 and fixedly connected to panel 2. Panel 2 and lower panel 3 are opposite to each other, and their opposite edges together define the air outlet. The air outlet communicates with the space inside the lower shell 5. Decorative panel 1 is installed on panel 2. Optionally, decorative panel 1 can be bolted to panel 2, or it can be welded to panel 2.

[0065] The aforementioned air outlet can optionally be fitted with a blade assembly 6, which forms multiple air guide channels within the outlet. Alternatively, an air guide plate 7 can be installed on the lower plate 3, positioned within the air outlet to guide airflow. An air outlet motor 8 is installed on the bottom side of the lower housing 5, with its outlet end connected to the airflow channels. The wiring harness 81 of the air outlet motor 8 is secured to the upper housing 4 and lower housing 5, and is connected to the vehicle's power supply, enabling the vehicle's power to power the air outlet motor 8.

[0066] The aforementioned panel 2 can be processed using painting or a leather-textured finish. A portion of the panel 2 extends to the outer side of the trim panel 1 for connection to the vehicle body. Panel 2 can be mounted to the upper shell 4 using bolts or snap-fit ​​connections. The upper shell 4 is connected to the lower shell 5 using bolts or snap-fit ​​connections. The lower panel 3 is connected to the side of the lower shell 5 and fixedly connected to panel 2.

[0067] By using the decorative panel described above in the dashboard air vent module, the decorative panel 1 can cover the panel 2 and has a partitioned visual effect, avoiding the use of multi-part spliced ​​decorative panels and reducing the manufacturing cost of the dashboard air vent module.

[0068] Reference Figure 4 , Figure 5 and Figure 7 As shown, in some embodiments, the top of the panel 2 is provided with an upright welding plate 21, and an arc-shaped segment is formed on the welding plate 21 that extends along the top surface of the panel 2. The decorative panel 1 is provided with a stiffener 14 corresponding to the welding plate 21 on the side facing away from the appearance surface 11. The stiffener 14 is welded and fused together with the welding plate 21.

[0069] This design ensures the structural stability of the welding plate 21 with its curved section. The heated welding plate 21 is less prone to tipping over under pressure, guaranteeing the welding quality between the welding plate 21 and the stiffener 14. Placing the decorative panel 1 on the panel 2 allows for the fusion welding of the stiffener 14 and the welding plate 21, facilitating automated batch welding and improving the production efficiency of the instrument panel air vent module.

[0070] Specifically, a mounting surface is formed on the top side of panel 2, and welding plate 21 is set on the mounting surface, perpendicular to the mounting surface. Welding plate 21 can be an arc-shaped plate, or it can be a corrugated plate with multiple arc-shaped ends. The radius of the arc segment of welding plate 21 is greater than or equal to 3mm and less than or equal to 8mm; the radius can be 7.5mm or 6mm. When there are multiple welding plates 21, the radii of the arc segments of different welding plates 21 can be equal, or at least two of the welding plates 21 can have unequal radii of their arc segments.

[0071] The decorative panel 1 described above has multiple protruding plates on the side facing away from the exterior surface 11, serving as reinforcing ribs 14. The thickness of the decorative panel 1 can be greater than or equal to 3 mm. The reinforcing ribs 14 are vertically arranged on the decorative panel 1 along its thickness direction. The dimension of the reinforcing rib 14 in the direction parallel to the decorative panel 1 is its width, which can be greater than or equal to 1 mm. The dimension of the reinforcing rib 14 in the thickness direction of the decorative panel 1 can be greater than or equal to 4 mm. When the reinforcing rib 14 is welded to the welding plate 21, the overlapping portion of the reinforcing rib 14 and the welding plate 21 has a dimension of 3 mm in the thickness direction of the decorative panel 1.

[0072] When welding plate 21 and stiffener 14 are welded together, the end face of welding plate 21 away from panel 2 is heated to a molten state, and stiffener 14 is inserted downward into the end of the molten welding plate 21. After the welding plate 21 cools, it is fixedly connected to stiffener 14.

[0073] When the welding plate 21 is heated, its structure softens. If the welding plate 21 is a straight plate, the pressure of the stiffener 14 on the welding plate 21 may cause it to tilt to one side, affecting the contact area between the stiffener 14 and the end of the molten welding plate 21. When the welding plate 21 has an arc-shaped section, after the welding plate 21 is heated, the arc-shaped section provides support to the stiffener 14 in a direction parallel to the mounting surface when the stiffener 14 presses down on the welding plate 21. This prevents the welding plate 21 from tilting to one side, ensuring the contact area between the stiffener 14 and the welding plate 21 during welding, and enabling a stable welded connection between the stiffener 14 and the welding plate 21.

[0074] When the aforementioned stiffening plate 14 and welding plate 21 are connected by fusion welding, it is usually necessary to heat the end of the welding plate 21 to a molten state, and then position the decorative plate 1 on the panel 2 so that the stiffening plate 14 is pressed into the molten end of the welding plate 21. After cooling, the stiffening plate 14 and welding plate 21 can be fixedly connected. Compared with the method of using bolts or snap-fit ​​structures to install the decorative plate 1 on the panel 2, there is no need to set up a structure for matching fasteners between the decorative plate 1 and the panel 2, or to set up an additional snap-fit ​​structure. During assembly, it is only necessary to place the decorative plate 1 on the panel 2 to weld the stiffening plate 14 and welding plate 21 together, which simplifies the connection operation between the decorative plate 1 and the panel 2 and facilitates batch automated welding.

[0075] Welding can be performed when the stiffening plate 14 comes into contact with the arc segment. Since the welding plate 21 has an arc segment, a certain positional tolerance is provided in the extension direction perpendicular to the welding plate 21, so that the stiffening plate 14 can be effectively welded to the welding plate 21 within a certain range, avoiding the influence of manufacturing errors on the welding effect of the decorative panel 1 and the panel 2.

[0076] Reference Figure 7 As shown, in some embodiments, multiple arc-shaped segments are sequentially formed on the welding plate 21 along the extension direction of the welding plate 21, and two adjacent arc-shaped segments protrude in opposite directions; the stiffener 14 is welded to the multiple arc-shaped segments.

[0077] With this configuration, multiple arc segments provide support structures for the welding plate 21 in two opposite directions, and multiple arc segments can have multiple welding points with the stiffener 14, thereby improving the stability of the welding connection between the welding plate 21 and the stiffener 14.

[0078] Specifically, the welding plate 21 is set on the mounting surface. Although the welding plate 21 has a curved arc segment, the welding plate 21 as a whole still extends in a certain direction. For example, the welding plate 21 extends along the length direction of the panel 2, and the arc segment bends along the width direction of the panel 2; or the welding plate 21 extends along the width direction of the panel 2, and the arc segment bends along the length direction of the panel 2; or the extension direction of the welding plate 21 can be selected to have an angle with the length direction of the panel 2, or the welding plate 21 is set at one edge of the panel 2 and extends along that edge.

[0079] Multiple arc-shaped segments protrude in opposite directions in a direction parallel to the mounting surface at the top of panel 2, so that the welding plate 21 forms a wave shape on the cross section parallel to the mounting surface. The cross sections of multiple arc-shaped segments of the welding plate 21 can be selected to form a sinusoidal wave shape.

[0080] The length of the aforementioned stiffening rib 14 is greater than or equal to the distance between the two ends of the welding plate 21, allowing the stiffening rib 14 to contact the end faces of multiple arc-shaped segments away from the panel 2. During welding, the welding plate 21 is heated, causing the end faces of multiple arc-shaped segments away from the panel 2 to be in a molten state. The decorative panel 1 is then placed on the top side of the panel 2, and the stiffening rib 14 contacts and melts with the multiple arc-shaped segments. This contact welding of the stiffening rib 14 with the multiple arc-shaped segments creates multiple welding points between the stiffening rib 14 and the welding plate 21, improving the stability of the welded connection between the stiffening rib 14 and the welding plate 21.

[0081] Reference Figure 7 As shown, in some embodiments, there are multiple welding plates 21, and at least two welding plates 21 are arranged with their extension directions intersecting; there are multiple stiffeners 14, and multiple stiffeners 14 are welded to multiple welding plates 21 in a one-to-one correspondence, and the extension direction of each stiffener 14 is parallel to the extension direction of the corresponding welding plate 21.

[0082] With this configuration, multiple welding plates 21 are welded to multiple stiffening plates 14, so that the connection points between the decorative panel 1 and the panel 2 are evenly distributed, improving the stability of the welded connection between the decorative panel 1 and the panel 2; and the welding plates 21 arranged in different directions are welded to the stiffening plates 14, so that the welding plates 21 provide multi-directional support for the decorative panel 1, improving the stability of the connection between the decorative panel 1 and the panel 2.

[0083] Specifically, the number of welding plates 21 can be two, or five or eight welding plates 21 can be set on the panel 2. Two of the welding plates 21 can be selected to extend along the first direction and the second direction respectively, or some of the welding plates 21 can be selected to extend along the first direction and the rest of the welding plates 21 can extend along the second direction. The first direction and the second direction can be perpendicular to each other, or the angle between the first direction and the second direction can be 30° or 60°.

[0084] The aforementioned stiffener 14 extends in the same direction as the corresponding welding plate 21, ensuring that the stiffener 14 and the welding plate 21 have a large welding area.

[0085] Reference Figures 2 to 6 and Figure 8 As shown, in some embodiments, the top of the panel 2 is provided with a plurality of positioning holes 22, and the side of the decorative panel 1 facing away from the exterior surface 11 is provided with a plurality of positioning elements 15, which are connected to the plurality of positioning holes 22 in a one-to-one manner.

[0086] With this configuration, multiple positioning elements 15 are inserted into multiple positioning holes 22, which can guide the decorative panel 1 to be positioned on the top side of the panel 2. Furthermore, when the decorative panel 1 is welded to the panel 2, it can limit the offset between the decorative panel 1 and the panel 2, making it convenient for the decorative panel 1 to be installed on the panel 2.

[0087] Specifically, the positioning hole 22 can be a through hole located at the top of panel 2, or a raised frame structure can be provided at the top of panel 2, with the interior of the frame structure being hollow, forming the positioning hole 22. The positioning element 15 is a column structure or a vertical plate structure set on the decorative panel 1. The positioning element 15 is inserted into the positioning hole 22 to restrict the relative movement of the decorative panel 1 and panel 2 in a direction parallel to the decorative panel 1. The cross-sectional dimension of the positioning hole 22 can be slightly larger than the dimension of the positioning element 15, so that after the positioning element 15 is inserted into the positioning hole 22, the relative position of the decorative panel 1 and panel 2 can be adjusted within a small range.

[0088] Reference Figure 7 and Figure 8 As shown, in some embodiments, the panel 2 is provided with a weight reduction hole 23, which is offset from the welding plate 21.

[0089] With this configuration, the weight-reducing hole 23 reduces the weight of the welding plate 21, thereby reducing the overall weight of the instrument panel air vent module.

[0090] Specifically, the weight-reducing holes are through holes set on the panel 2. The weight-reducing holes are spaced apart from the welding plate 21 to avoid the weight-reducing holes affecting the structural stability of the welding plate 21. It is possible to have multiple weight-reducing holes on the panel 2, with the multiple weight-reducing holes spaced apart on the panel 2. The multiple weight-reducing holes can be arranged in one direction, or they can be evenly distributed on the panel 2.

[0091] A third aspect of this application provides a vehicle including an instrument panel vent module as described in any of the preceding claims.

[0092] With this design, the decorative panel 1 has a simple structure and low manufacturing cost. Furthermore, the decorative panel 1 gives the dashboard air vent module a good visual effect. Using the above-mentioned dashboard air vent module in the vehicle can reduce manufacturing costs and enhance the aesthetics of the vehicle interior.

[0093] When the decorative panel, dashboard air vent module and vehicle provided in this application embodiment are used, multiple diaphragms 13 are placed in the mold, the multiple diaphragms 13 are attached to the inner wall of the mold, and the part of the inner wall of the mold corresponding to the partition structure 12 has a positioning function for the multiple diaphragms 13. The decorative panel 1 is formed by injection molding in the mold, and the diaphragms 13 on both sides of the partition structure 12 on the decorative panel 1 are exposed on the outer surface 11.

[0094] The ends of multiple welding plates 21 away from the panel 2 are heated until they are molten. The decorative panel 1 is placed on the top side of the panel 2. Multiple positioning pieces 15 are inserted into multiple positioning holes 22 one by one. The decorative panel 1 is pressed down so that the ribs 14 are pressed into the ends of the molten welding plates 21. The ribs 14 are combined with multiple arc-shaped segments of the welding plates 21. After the welding plates 21 cool, they are welded to the ribs 14. Multiple ribs 14 are simultaneously welded to multiple welding plates 21 to fix the decorative panel 1 on the panel 2.
