[0002] The vehicle interior includes side panel and roof panel. The side panel mainly provides shielding for the body sheet metal, wiring harness, seat belt and other accessories, so as to obtain a good interior appearance and provide a safe and comfortable riding environment for the driver and passengers. Usually, hooks are set on the side panel for hanging items.

[0003] At present, there are two main types of vehicle interior hook structures: snap-on rotatable hooks and screw-on rotatable hooks. Among them, the snap-on rotatable hook includes an injection-molded hook body and a base, which are snap-on together via a central axis and snap-on and fixed to the side frame via the base. The disadvantage of this structural form is that it has poor load-bearing capacity and is easy to fall off; the screw-on rotatable hook is usually arranged at the bottom of the luggage compartment to bind items and has no function of hanging items. Although the hook of this structure has high load-bearing strength, its structure is relatively complex and requires a dedicated screw hole or connection bracket to be set on the body sheet metal. Not only is its own weight and installation space large, but the cost is also high. Utility Model Content

In the description of the present application, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0026] Please also read Figures 1 to 3 The decorative panel hook structure provided by the utility model is now described. The decorative panel hook structure includes a decorative panel body 10, which has a clearing area 11, and the lower boundary of the clearing area 11 is partially convex to form a hook rib 12; the decorative panel body 10 is provided with a first flange 13 along the boundary of the clearing area 11, and the edge of the hook rib 12 is provided with a second flange 14, the first flange 13 and the second flange 14 are both folded toward the outside of the vehicle body, and the two ends of the second flange 14 are respectively connected to the two ends of the first flange 13 as a whole.

[0027] It should be noted that, in the present embodiment, the trim panel body 10 may be a side trim panel in a vehicle cockpit or a trim panel in a vehicle luggage compartment, which is not limited here.

[0028] In this embodiment, an air avoidance area 11 is set on the side panel, and the hook rib 12 is formed by a local area of ​​the lower boundary of the air avoidance area 11 that protrudes upward, and a slot suitable for a hanging part of an object, such as a hanging rope, is formed between the hook rib 12 and the boundary of the air avoidance area 11, and the hanging part is hung on the hook rib 12 after passing through the slot. Specifically, the hook rib 12 can occupy the middle position of the lower boundary of the air avoidance area 11 and protrude upward to the middle height position of the air avoidance area 11; on the basis of the above, in order to ensure the boundary strength of the air avoidance area 11, a first flange 13 is set along the boundary of the air avoidance area 11, and a second flange 14 is set along the edge of the hook rib 12, and the first flange 13 and the second flange 14 are connected to form a closed loop. This not only can avoid the boundary of the air avoidance area 11 from being torn by force, but also can improve the structural strength and load-bearing capacity of the hook rib 12.

[0029] In this embodiment, the decorative panel body 10 can be a molded part, and based on the molded decorative panel body 10, a later secondary injection molding is performed at the position where the decorative panel hook needs to be set to form the above-mentioned air avoidance area 11, hook ribs 12, first flanges 13 and second flanges 14. During the secondary injection molding, ABS (Acrylonitrile Butadiene Styrene), PC (Polycarbonate) and ABS mixture or PP-TD20 (polypropylene containing 20% ​​talcum powder) can be used. These engineering plastics that can meet the load-bearing strength requirements of the hook are not only conducive to reducing costs, but also can improve the connection reliability and structural strength between the hook ribs 12 and the lower boundary of the air avoidance area 11, and at the same time can also improve the flexibility of setting the decorative panel hook position.

[0030] In order to avoid problems such as breakage of the hook rib 12 or cracking of the trim body 10 near the air avoidance area 11 due to excessive use, a maximum load-bearing mark 101 can be set on the interior surface 100 near the air avoidance area 11 or directly on the surface of the hook rib 12 to remind drivers and passengers not to hang heavy objects that exceed the structural bearing capacity, thereby ensuring the long-term service life of the trim hook structure.

[0031] Compared with the prior art, the trim panel hook structure provided in the present embodiment provides an air avoidance area 11 on the trim panel body 10, and utilizes the lower boundary of the air avoidance area 11 to partially bulge upward to form hook ribs 12 for hanging items. Not only is the structure simple and conducive to weight reduction, it can be integrally formed with the trim panel body 10, and there is no need to provide a corresponding connection structure on the body sheet metal, thereby reducing processing costs. In addition, the first flange 13 can be used to increase the boundary strength of the air avoidance area 11, and the second flange 14 connected to the first flange 13 to form a closed loop connection can be used to increase the structural strength of the hook rib 12, thereby improving the load-bearing capacity of the trim panel hook.

[0032] In some embodiments, see Figure 2 and Figure 3 , one side of the decorative plate body 10 forms the interior surface 100, and a sealing plate 15 is provided at one end of the first flange 13 away from the interior surface 100, and a hanging gap 16 is provided between the sealing plate 15 and the hook rib 12. By providing the sealing plate 15, the end of the first flange 13 away from the interior surface 100 is blocked and connected, thereby converting the hole or sleeve structure into a cavity structure, which can not only improve the structural strength, but also shield the air avoidance area 11 to prevent the body sheet metal from being exposed and affecting the interior quality; on this basis, the hanging part of the object can be embedded by using the hanging gap 16 between the sealing plate 15 and the hook rib 12, thereby preventing the object from falling off and improving the hanging stability of the object.

[0033] To facilitate one-piece molding, please combine Figure 3 and Figure 6 It is understood that a die-out hole 151 is provided on the sealing plate 15, and the die-out hole 151 corresponds to the position of the hook rib 12. By setting the die-out hole 151, the position of the hook rib 12 can be avoided, so that the die is easily ejected to the outside of the vehicle body.

[0034] Furthermore, in this embodiment, a third flange 17 is provided at the top of one end of the second flange 14 facing away from the interior trim surface 100 . The third flange 17 is folded downward and forms a core-pulling cavity 18 between the third flange 17 and the hook rib 12 .

[0035] By setting the third flange 17, a double-layer structure can be formed with the hook rib 12, thereby improving the load-bearing capacity. During the injection molding process, the movable mold 30 can be partially passed through the ejection hole 151 to form the surface of the third flange 17. At the same time, the surface of the core-pulling slide 40 inserted into the core-pulling cavity 18 from bottom to top is used as the surface of the second flange 14 and the hook rib 12. After the injection molding is completed, the movable mold 30 is pulled out along the axial direction of the ejection hole 151 and the core-pulling slide 40 is pulled downward, thereby realizing one-piece molding, which not only improves the structural integrity and strength, but also saves processing costs.

[0036] It should be noted that the core-pulling cavity 18 has a first draft angle for downward ejection. Specifically, the first draft angle can be formed based on the gradually increasing distance between the third flange 17 and the hook rib 12 from top to bottom. By setting the first draft angle, it is ensured that the core-pulling slide 40 can be smoothly ejected downward during the injection molding process, thereby ensuring the molding quality.

[0037] For some possible implementations, see Figure 3 The lower end of the third flange 17 is provided with a shielding rib 19, which passes through the die-out hole 151 in a direction away from the interior trim surface 100. Since the die-out hole 151 may cause the body sheet metal to be exposed, the shielding rib 19 is provided through the die-out hole 151 to shield the body sheet metal, which can prevent the body sheet metal from being exposed and does not affect the smooth demolding of the mold.

[0038] It should be understood that, in this embodiment, Figure 3 As shown, there is a second draft angle between the first flange 13 and the second flange 14 for demolding toward the interior of the vehicle body (i.e., toward the interior trim surface 100). Specifically, a certain angle is formed between the first flange 13 and the second flange 14, and based on the angle, a notch structure suitable for demolding is formed between the first flange 13 and the second flange 14, which is wide outside and narrow inside, thereby reducing the difficulty of demolding and also helping to improve the molding quality.

[0039] Based on the same inventive concept, Figures 3 to 6It is understood that the embodiment of the present application also provides a hook forming mold, including a fixed mold 20 and a movable mold 30, and a cavity is formed between the fixed mold 20 and the movable mold 30, and the cavity is used to integrally form the above-mentioned decorative panel hook structure.

[0040] It should be noted that, in this embodiment, the molding surface of the fixed mold 20 can be used to form the interior surface 100 of the decorative panel body 10, and the molding surface of the movable mold 30 is used to form the back side of the decorative panel body 10. The cavity enclosed by the movable mold 30 and the fixed mold 20 enables the structural features such as the air avoidance area 11, the hook rib 12, the first flange 13, and the second flange 14 to be integrally formed with the decorative panel body 10, thereby reducing processing costs and also helping to improve structural strength.

[0041] Compared with the prior art, the decorative panel hook structure provided in the present embodiment can integrally form the hook rib 12, the first flange 13 and the second flange 14 on the decorative panel body 10 through the cavity enclosed by the fixed mold 20 and the movable mold 30, thereby simplifying the structure of the decorative panel hook, reducing the weight and manufacturing cost of the decorative panel hook, and utilizing the connected first flange 13 and second flange 14 to improve the structural strength of the hook rib 12, thereby improving the load-bearing capacity of the decorative panel hook; in addition, the hook molding mold provided in the present embodiment can perform secondary injection molding at any required position of the decorative panel body 10 to obtain the above-mentioned decorative panel hook structure, thereby improving the flexibility of the setting position of the above-mentioned decorative panel hook structure.

[0042] In some embodiments, the hook forming mold further includes a core-pulling mold 40; wherein a first cavity 50 is formed between the fixed mold 20 and the movable mold 30, and the first cavity 50 is used to form the first flange 13 and the closing plate 15 connected to the first flange 13; a second cavity 60 is formed between the fixed mold 20 and the core-pulling mold 40, and the second cavity 60 is used to form the second flange 14 and the hook rib 12; a third cavity 70 is formed between the movable mold 30 and the core-pulling mold 40, and the third cavity 70 is used to form the third flange 17 connected to the second flange 14, and the shielding rib 19 connected to the third flange 17.

[0043] It should be understood that the hook molding mold provided in this embodiment can be used to perform secondary injection molding on the molded trim body 10 at the position where the trim hook needs to be set according to design requirements, thereby obtaining the above-mentioned trim hook structure.

[0044] Specifically, due to the existence of the air avoidance area 11, the decorative panel body 10 is divided into two parts, an upper and a lower part, in the air avoidance area 11, where the surface of the fixed mold 20 matches the interior decoration surface 100 of the decorative panel body, and at the same time, the hook rib 12, the first flange 13, the second flange 14, the closing plate 15 and other surfaces facing the interior decoration surface 100 are also formed based on the surface of the fixed mold 20; the movable mold 30 is mainly used to form the surfaces of the first flange 13, the closing plate 15, the third flange 17, the shielding rib 19 and other components away from the interior decoration surface 100; the surface of the core pulling sliding mold 40 is used to form the back of the lower half of the decorative panel body 10, the cavity wall of the core pulling cavity 18, and the lower surface of the shielding rib 19; of course, considering that the second flange 14 is formed on the top of the hook rib 12, the above-mentioned second cavity 60 and the third cavity 70 are connected.

[0045] When the demolding operation is performed after injection molding, the core-pulling slide 40 can be first pulled downward from the core-pulling cavity 18, and then the movable mold 30 can be moved in the direction away from the interior trim surface 100 to separate the movable mold 30 from the fixed mold 20, and finally the decorative panel body 10 can be removed from the fixed mold 20. In this way, the above-mentioned decorative panel hook structure is integrally formed on the decorative panel body 10, which not only has a low processing cost, but also can ensure the integrity of the structure and improve the load-bearing capacity.

[0046] It can be seen that the above-mentioned hook forming mold can be used to flexibly set the trim panel hook structure at any position of the trim panel body 10 and form an integrated structure, thereby improving the position flexibility of the trim panel hook structure and reducing processing costs.

[0047] Based on the same inventive concept, an embodiment of the present application also provides a vehicle with the above-mentioned trim panel hook structure. Compared with the prior art, the trim panel assembly of the vehicle in this embodiment can not only simplify the structure of the trim panel hook, thereby reducing the weight and manufacturing cost of the trim panel hook, but also can utilize the connected first flange 13 and second flange 14 to improve the structural strength of the hook rib 12, thereby improving the load-bearing capacity of the trim panel hook.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
