[0031] As Figures 1 - 4 shown, the front bumper skin assembly includes a front bumper skin 1, a grille reinforcement bracket 2, and an upper grille 3.

[0032] The grille reinforcement bracket 2 includes a first mounting portion 21, a second mounting portion 22, and a third mounting portion 23 that are connected in sequence. The first mounting portion 21 is used to connect to the vehicle body, and the third mounting portion 23 is detachably connected to the front bumper skin 1. The first end of the upper grille 2 is snap-connected to the second mounting portion 22, the second end of the upper grille 3 is detachably connected to the first mounting portion 21, and an accommodation cavity is formed between the upper grille 3, the first mounting portion 21, and the second mounting portion 22.

[0033] Set the front direction of the vehicle as the front, the rear direction as the rear, the direction away from the ground as the upper, and the direction towards the ground as the lower. When assembling the front bumper skin assembly, connect the third mounting portion 23 of the grille reinforcement bracket 2 to the front bumper skin 1 in the front-rear direction, snap the first end of the upper grille 3 onto the second mounting portion 22 of the grille reinforcement bracket 2 from top to bottom through a buckle to achieve the preliminary connection between the upper grille 3 and the grille reinforcement bracket 2. Then connect the second end of the upper grille 3 to the first mounting portion 21 of the grille reinforcement bracket 2 through a connecting member to achieve the further connection between the upper grille 3 and the grille reinforcement bracket 2. Next, fix the grille reinforcement bracket 2 to the vehicle body middle bracket 9 to achieve the connection to the vehicle body. When the front bumper skin assembly is installed on the front bumper and further installed on the vehicle body, when it is necessary to replace the upper grille 3, it is not necessary to disassemble the entire front bumper. Open the engine hood, disassemble the connecting member connecting the upper grille 3 and the first mounting portion 21, release the connection between the upper grille 3 and the first mounting portion 21, and then pull out the upper grille 3 forcefully from bottom to top to release the snap connection between the upper grille 3 and the second mounting portion 22. Then the upper grille 3 is completely independent of the grille reinforcement bracket 2, and the disassembly of the upper grille 3 is completed. Then install the new upper grille 3 to the grille reinforcement bracket 2 according to the original steps.

[0034] By adopting the front bumper skin assembly of the present invention, it is not necessary to disassemble the entire front bumper to achieve the disassembly and assembly of the upper grille, which improves the flexibility of the disassembly and assembly of the upper grille, is beneficial to the personalized customization and selection in the market, gives customers more choice space, saves after-sales working hours, and avoids part damage and matching problems caused by multiple disassembly and assembly of the bumper.

[0035] In this embodiment, as Figure 2 、 Figure 3As shown, the grille reinforcement bracket 2 includes a first mounting portion 21, a second mounting portion 22, and a third mounting portion 23 that are connected in sequence. Among them, the first mounting portion 21 is integrally bent into a horizontal section and a vertical section. The vertical section is connected to the second mounting portion 22, and the connection between the vertical section and the second mounting portion 22, as well as the connection between the second mounting portion 22 and the third mounting portion 23, are approximately perpendicular. The surface curvature of the third mounting portion 23 matches the front bumper skin 1 connected to it. As Figure 3 shown, in this embodiment, the third mounting portion 23 is snap-connected to the front bumper skin 1. A plurality of snap connectors are provided on the upper side, lower side, and right side of the third mounting portion 23. Corresponding snap holes are respectively opened at the corresponding positions of the front bumper skin 1. Each snap connector is inserted into the corresponding snap hole to achieve the detachable connection between the third mounting portion 23 and the front bumper skin 1. As Figure 4 shown, in this embodiment, the upper grille 3 is integrally bent into an obtuse angle. The first end of the upper grille 3, that is Figure 4 the lower end of the upper grille 3 described in Figure 4 is snap-connected to the nearly horizontal second mounting portion 22. The second end of the upper grille 3, that is

[0036] the left end of the upper grille 3 described in

[0037] is screwed to the horizontal section of the first mounting portion 21. Installation holes through which the screws pass are pre-opened on both of them. In this embodiment, the material selected for the upper grille is the commonly used ABS, which has good adaptability and can be used as the base material for spray-painted parts, electroplated parts, and spray-painted parts after electroplating, providing a richer appearance selection. According to the actual application situation, the specific shapes of the first mounting portion 21, the second mounting portion 22, and the third mounting portion 23 can be adjusted according to the vehicle model. Other detachable connection methods other than snap connection can be adopted between the third mounting portion 23 and the front bumper skin 1, and other detachable connection methods other than screw connection can be adopted between the upper grille 3 and the first mounting portion 21. Figure 2 and Figure 4As shown, after the upper grille 3 is installed on the grille reinforcement bracket 2, the space enclosed between the upper grille 3, the first mounting portion 21 and the second mounting portion 22 is the accommodation cavity. No other components need to be installed on the upper grille 3, and there is no interference with the second mounting portion 22. When it is necessary to replace the upper grille 3 with a through lamp, since a lamp body is installed inside the through lamp, interference will occur with the second mounting portion 22 after being connected to the grille reinforcement bracket 2. Therefore, an avoidance hole 4 is opened at the corresponding position of the second mounting portion 22 to smoothly install the through lamp. As Figure 2 shown, in this embodiment, the avoidance hole 4 is opened at the central position of the second mounting portion 22. According to the actual application situation, the number of avoidance holes 4 opened on the second mounting portion 22 and the specific opening positions can be adjusted.

[0038] Figure 5 For Figure 2 shown is a schematic diagram of the connection process of the windshield cover plate and the grille reinforcement bracket. As Figure 2 、 Figure 5 shown, optionally, the front bumper skin assembly further includes a windshield cover plate 5. The windshield cover plate 5 is detachably connected to the second mounting portion 22 in the accommodation cavity and covers the avoidance hole 4. By providing the windshield cover plate 5, it is possible to prevent the air flow from passing through the avoidance hole 4, thereby effectively controlling the air flow trajectory, reducing noise and improving the vehicle's aerodynamic performance.

[0039] In this embodiment, as Figure 5 shown, the windshield cover plate 5 is generally in the shape of a quadrilateral plate, and the cross-sectional area is larger than the area of the avoidance hole 4. And mounting holes are pre-opened. After the windshield cover plate 5 is placed on the second mounting portion 22 and covers the avoidance hole 4, screws are used to pass through the mounting holes on the windshield cover plate 5 and the corresponding second mounting portion 22 to achieve the detachable connection between the two. In this embodiment, the windshield cover plate 5 uses PP+EPDM as the plastic base material. According to the actual application situation, the shape and size of the windshield cover plate 5 can be adjusted as long as it can cover the avoidance hole 4, and the windshield cover plate 5 and the second mounting portion 22 can also adopt other detachable connection methods other than screw connection.

[0040] Figure 6 For Figure 2 shown is a schematic diagram of the connection process of the modal bracket and the grille reinforcement bracket. As Figure 2 、 Figure 6As shown, optionally, the front bumper skin assembly further includes a modal bracket 6. The opposite ends of the modal bracket 6 are respectively connected to the side of the second mounting portion 22 and the third mounting portion 23 facing away from the front bumper skin 1. The modal bracket 6 can play a strong supporting role to ensure that when the upper grille 3 is replaced with a through lamp, the modal requirements can always be met.

[0041] In this embodiment, as Figure 6 shown, an extension portion 231 for fixing the modal bracket 6 extends horizontally on the third mounting portion 23. The extension portion 231 is nearly parallel to the second mounting portion 22. The modal bracket 6 is vertically placed between the extension portion 231 and the second mounting portion 22, and the opposite ends in its extending direction are respectively connected to the extension portion 231 and the second mounting portion 22 by screws. The material selected for the modal bracket 6 is ASA, which has strong rigidity, plays a supporting role on the back of the front bumper skin assembly, improves the front-end mode and reduces the front-end sinking amount. The modal bracket 6 is beneficial to the mode and low-speed collision, but not beneficial to pedestrian protection; the avoidance hole 4 provided on the grille reinforcement bracket 2 is not beneficial to low-speed collision, but beneficial to pedestrian protection and heat dissipation. Finding a balance between the two can meet all regulatory and performance requirements. According to the actual application situation, the specific shape and size of the modal bracket 6 can be adjusted, and the specific connection position and connection method between the modal bracket 6 and the second mounting portion 22 and the third mounting portion 23 can be adjusted.

[0042] Optionally, a weight reduction hole 7 is provided on the third mounting portion 23. With this setting, the weight of the front bumper skin assembly can be reduced, and further the weight of the whole vehicle can be reduced, which is beneficial to the lightweight production of the whole vehicle.

[0043] In this embodiment, as Figure 2 shown, two weight reduction holes 7 are provided in the middle position of the third mounting portion 23, both of which are irregular in shape. The third mounting portion 23 is connected to the front bumper skin 1, and the weight reduction holes 7 are covered by the front bumper skin 1. Therefore, the provided weight reduction holes 7 on it will not cause noise or reduce the vehicle aerodynamic performance. According to the actual application situation, the number of the weight reduction holes 7 and the specific opening position on the third mounting portion 23 can both be adjusted.

[0044] Optionally, a weight reduction hole 7 is provided on the second mounting portion 22. With this setting, the weight of the front bumper skin assembly can be reduced, and further the weight of the whole vehicle can be reduced, which is beneficial to the lightweight production of the whole vehicle.

[0045] In this embodiment, as Figure 2As shown, three rectangular weight-reducing holes 7 of different specifications are spaced apart on the vertical section of the first mounting portion 21. Since the vertical section of the first mounting portion 21 is not involved in the sealing area, the weight-reducing holes 7 opened thereon will not cause noise or reduce the aerodynamic performance of the vehicle. According to the actual application situation, the number of the weight-reducing holes 7 and their specific opening positions on the first mounting portion 21 can be adjusted.

[0046] Figure 7 For Figure 2 Schematic diagram of the clamping relationship between the clamping portion of the upper grille shown and the second mounting portion of the grille reinforcement bracket; Figure 8 For Figure 7 A-A' cross-sectional view of the clamping relationship between the clamping portion and the second mounting portion shown. As Figure 2 、 Figure 7 And Figure 8 As shown, optionally, the second mounting portion 22 is provided with a clamping hole; the upper grille 3 is connected with a clamping portion 8, and the clamping portion 8 is inserted into the clamping hole to realize the clamping connection between the upper grille 3 and the second mounting portion 22, and the cross-section of the clamping portion 8 is set to be arc-shaped. Compared with the traditional straight-piece clamping structure, the arc-shaped clamping structure reduces the effective clamping area with the mating part, increases the deformation space, has a smaller clamping force than the traditional structure in the clamping direction, and is easier to disassemble.

[0047] As Figure 2 Shown, in this embodiment, at the first end of the upper grille 3, that is Figure 2 At the lower end of the upper grille 3 described in, a plurality of the clamping portions 8 are spaced and connected, and a plurality of rectangular clamping holes are spaced apart at the corresponding positions of the second mounting portion 22. As Figure 7 、 Figure 8 Shown, the clamping portion 8 is inserted into the clamping hole to realize the clamping connection between the upper grille 3 and the second mounting portion 22. According to the actual application situation, the arc curvature, the set number of the clamping portions 8 and their specific connection positions on the upper grille 3 can be adjusted, and the clamping holes opened on the second mounting portion 22 are adjusted accordingly.

[0048] Optionally, the grille reinforcement bracket 2 is made of ASA material.

[0049] ASA has good mechanical and physical properties. It can not only resist degradation, aging and fading caused by ultraviolet irradiation, but also has strong protection against decomposition or discoloration caused by oxidation in the atmosphere and high temperature in the processing process. Thus, the anti-aging and weather resistance of the material are greatly improved, and it is an anti-static material, which can make less dust accumulate on the surface.

[0051] The following will further introduce the process of replacing the upper grille for the through lamp in combination with Figure 9 and Figure 10 :

[0052] In this embodiment, the structure of the through lamp 11 is similar to that of the upper grille 3, except that a lamp body is installed inside. First, remove the multiple screws connecting the upper grille 3 and the first mounting portion 21 to release the connection between the upper grille 3 and the first mounting portion 21. Then, pull out the clamping portion 8 of the upper grille 3 from the clamping hole in the second mounting portion 22 from bottom to top to release the clamping connection between the upper grille 3 and the second mounting portion 22, and take out the upper grille 3. Next, remove the multiple screws connecting the windshield cover plate 5 and the second mounting portion 22 to release the connection between the windshield cover plate 5 and the second mounting portion 22, and take out the windshield cover plate 5. Subsequently, snap the first end of the through lamp 11 onto the second mounting portion 22 from top to bottom, and then connect the second end of the through lamp 11 to the first mounting portion 21 with screws, thus completing the process of replacing the upper grille for the through lamp.
