Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicles, in particular to an A-pillar outer trim panel structure and a vehicle. BACKGROUND

[0002] The A-pillar outer trim panel covers the outer side of the A-pillar, and the application of the A-pillar outer trim panel can make up for the defect of insufficient stamping size of the body side outer panel. The application of the current A-pillar outer trim panel tends to be widespread, and the profile design of the A-pillar outer trim panel is also more flexible.

[0003] However, the A-pillar outer trim panel is in a long strip shape as a whole, and the overall torsional rigidity is insufficient after installation and is prone to twist and sway under stress, which is of poor quality. Moreover, when the vehicle appearance requires double colors, double-color spraying needs to be performed on different parts of the A-pillar outer trim panel, which increases the spraying difficulty, reduces the quality, and increases the cost at the intersection of different colors. SUMMARY

[0004] The present application provides an A-pillar outer trim panel structure, which comprises an outer trim panel lower body and an outer trim panel upper body. The position where the outer trim panel lower body and the outer trim panel upper body meet corresponds to the root position of the hood of the vehicle in the width direction, and the outer trim panel lower body and the outer trim panel upper body are respectively fixed to the vehicle body.

[0005] In a specific embodiment, one of the outer trim panel lower body and the outer trim panel upper body is provided with a clamping foot, and the other is provided with a clamping hole. The clamping foot is inserted into the clamping hole and gap-fitted with the clamping hole.

[0006] In a specific embodiment, the outer trim panel upper body is provided with at least one clasp, and the A-pillar of the vehicle body is provided with a corresponding insertion hole. The clasps are distributed in the length direction of the outer trim panel upper body.

[0007] In a specific embodiment, the distance between the clasp and the outer contour of the inner side of the outer trim panel upper body is less than or equal to 30 mm.

[0008] In a specific embodiment, the outer side of the outer trim panel upper body is provided with an outward turning edge towards the A-pillar of the vehicle body, and a support rib is arranged between the outward turning edge and the A-pillar.

[0009] In a specific embodiment, the outer trim panel lower body comprises a side plate and a top plate. The top plate is used to connect with the hood, and the side plate is used to connect with the fender. The rear end of the outer trim panel lower body is connected with the lower end of the outer trim panel upper body.

[0010] In a specific embodiment, the rear end of the side plate has a bevel towards the rear side, and the bevel is butt-jointed with the window frame of the quarter window of the vehicle. The rear end of the top plate has a notch, and the notch is matched with the outer peripheral wall of the lower end of the outer trim panel upper body.

[0011] And / or, the lower body of the exterior trim panel further includes a mounting portion, which is connected to the rear end of the roof panel and located on the inner side of the upper body of the exterior trim panel. The mounting portion is fixed to the vehicle body by fasteners, and the mounting portion has a mating surface that is interference-fitted with the windshield of the vehicle.

[0012] In one specific embodiment, the mating surface is provided with a soft rubber layer or a rubber pad.

[0013] This application provides a vehicle including a hood, a fender, an A-pillar, and an A-pillar exterior trim structure as described in any of the above claims covering the outside of the A-pillar, the lower part of the exterior trim structure being located between the hood and the fender.

[0014] In one specific embodiment, the lower body of the exterior trim panel is provided with bolts, the vehicle body is provided with waist-shaped holes, the bolts can be inserted into the waist-shaped holes for fixing, and the bolts can be adjusted in position at the waist-shaped holes to adjust the surface difference between the lower body of the exterior trim panel and the vehicle's hood.

[0015] In this application, the upper and lower sections of the A-pillar exterior trim panel structure are separate and independent structures. The installation of the lower section is not affected by the installation direction of the upper section, making installation more flexible and avoiding interference with surrounding components. Moreover, the separate design, with each section being shorter than a monolithic A-pillar exterior trim panel structure, reduces the likelihood of twisting and swaying.

[0016] Furthermore, the separate design of the upper and lower exterior trim panels facilitates the application of different paint colors when the vehicle has variations in appearance. When a vehicle is designed with two distinct colors, the hood typically serves as the dividing line, meaning the body portion between the roof and the hood is a different color. Since the lower and upper exterior trim panels are separated at the base of the hood, masking is unnecessary during painting, allowing for separate painting of the two sections, simplifying the painting process.

[0039] In order to make the person skilled in the art better understand the scheme of the present application, the present application is further described in detail below in combination with the drawings and specific embodiments.

[0040] Please refer to Figure 1 , Figure 1 The figure is a schematic view of the A-pillar outer panel structure 1 in the embodiment of the present application installed on the vehicle body.

[0041] The A-pillar outer panel structure 1 in the embodiment includes an outer panel lower body 12 and an outer panel upper body 11. The position where the outer panel lower body 12 and the outer panel upper body 11 meet corresponds to the root position of the hood 3 of the vehicle in the width direction, i.e. the left-right direction of the vehicle. Figure 1 In the embodiment, the vehicle includes a hood 3, a signal lamp cover 4, a fender 6, and a front windshield 7. The root of the hood 3, i.e. the rear end of the hood 3, meets the front windshield 7. The root of the hood 3 and the lower end of the front windshield 7 are connected by a windshield gutter 2. The position where the outer panel lower body 12 and the outer panel upper body 11 meet corresponds to the root of the hood 3 in the width direction, i.e. the position where the outer panel lower body 12 and the outer panel upper body 11 meet and the root of the hood 3 are substantially in the same width direction. The side of the hood 3 meets the outer panel lower body 12, and the hood 3 does not meet the outer panel upper body 11. In addition, the outer panel lower body 12 and the outer panel upper body 11 are respectively fixed to the vehicle body, i.e. both of them are fixed to the vehicle body.

[0042] In this way, the outer panel upper body 11 and the outer panel lower body 12 of the A-pillar outer panel structure 1 are separately arranged and are independent structures. The outer panel lower body 12 is installed without being affected by the installation direction of the outer panel upper body 11, which makes the installation more flexible, Figure 1 In the embodiment, the outer panel lower body 12 is arranged between the hood 3, the signal lamp cover 4, and the fender 6. The separately arranged outer panel lower body 12 has higher installation flexibility, which is beneficial to matching with the hood 3, the signal lamp cover 4, and the fender 6 and preventing interference with the surrounding components due to the installation of the outer panel upper body 11. In addition, the separately arranged outer panel lower body 12 has a relatively shorter length than the integral A-pillar outer panel structure, and the torsional vibration and shaking can be improved.

[0043] In addition, since the outer panel upper body 11 and the outer panel lower body 12 are separately arranged, it is beneficial to the spraying operation of different color paints when the vehicle has a color difference in appearance. When the vehicle is arranged in different colors, for example, in a two-color arrangement, the vehicle body is generally divided into different colors at the hood 3, i.e. the part of the vehicle body between the roof and the hood 3 and the hood 3 are different colors. Since the outer panel lower body 12 and the outer panel upper body 11 are separately arranged at the root of the hood 3, it is not necessary to shield during spraying, and the outer panel lower body 12 and the outer panel upper body 11 can be sprayed separately, which is more convenient for spraying operation.

[0044] Please continue to refer to Figures 2-4 , Figure 2 For Figure 1 the schematic view of the A-pillar outer panel structure 1 at the position A; Figure 3 For Figure 2 the cross-sectional view along A-A direction; Figure 4 For Figure 2 the schematic view of the outer panel upper body 11 of the A-pillar outer panel structure 1.

[0045] In this embodiment, the outer panel upper body 11 is provided with at least one buckle 112, Figure 4 In this embodiment, the outer panel upper body 11 is provided with a plurality of buckles 112, and the plurality of buckles 112 are distributed along the length direction of the outer panel upper body 11. The outer panel upper body 11 is wrapped around the A-pillar 9 of the vehicle and extends in the substantially vertical direction, and the upper end of the outer panel upper body 11 is connected to the roof, and the lower end substantially corresponds to the position of the lower side of the front windshield 7, so the length direction of the outer panel upper body 11 is the direction from the upper end to the lower end. The A-pillar 9 of the vehicle body is provided with a plurality of insertion holes corresponding to the plurality of buckles 112, as shown in Figure 3 The buckle 112 of the outer panel upper body 11 can be inserted into the insertion hole of the A-pillar 9, and the buckle 112 and the insertion hole are in clamping cooperation, so that the outer panel upper body 11 and the A-pillar 9 can be effectively positioned, and the outer panel upper body 11 is prevented from twisting and shaking when subjected to external force.

[0046] The outer panel upper body 11 described above is cooperated with the insertion hole of the A-pillar 9 through the buckle 112, and the outer panel upper body 11 is also fixed to the vehicle body through the bolt 114. As shown in Figure 3 The outer panel upper body 11 includes an outer plate 115 and an inner plate 113, and the inner plate 113 is welded to the inner side of the outer plate 115 to increase the strength of the outer panel upper body 11.

[0047] In addition, as shown in Figure 3 The distance D1 between the buckle 112 and the outer contour of the inner side of the outer panel upper body 11 is less than or equal to 30mm, and the inner side is the side of the outer panel upper body 11 close to the front windshield 7. This distance helps to further prevent the outer panel upper body 11 from twisting and shaking.

[0048] In addition, the outer side of the outer panel upper body 11 in this embodiment is also provided with an outward turning edge 111 towards the A-pillar 9 of the vehicle body, and a support rib can be provided between the outward turning edge 111 and the A-pillar 9, which also increases the strength of the outer panel upper body 11. In this way, in combination with the design of the buckle 112 described above, the twisting and shaking of the outer panel upper body 11 under external force and the collapse of the outer panel upper body 11 when pressed can be avoided.

[0049] In combination with Figure 5 , 6 understand, Figure 5 forFigure 2 Fig. 2 is a schematic view of the outer panel lower body 12 of the middle A-pillar outer panel structure 1; Figure 6 For Figure 2 Fig. 3 is a sectional view along the direction of B-B.

[0050] As Figure 6 shown, the rear end of the outer panel lower body 12 is provided with a clamping leg 12.1, and the lower end of the outer panel upper body 11 is provided with a clamping hole 11a, the clamping leg 12.1 is inserted into the clamping hole 11a and is in clearance fit with the clamping hole 11a. Through the clearance fit of the clamping leg 12.1 and the clamping hole 11a, the outer panel lower body 12 and the outer panel upper body 11 are mainly limited and positioned, and the two are not fixedly connected. Since the two are in clearance fit, the outer panel upper body 11 and the outer panel lower body 12 have a certain amount of movement, and the installation position of any one of the two will not affect the installation of the other. At this time, the above-mentioned bolt 114 for fixing the outer panel upper body 11 can be arranged at the lower end of the outer panel upper body 11, so that the lower end of the outer panel upper body 11 is more firm and can provide a firm positioning and installation carrier for the outer panel lower body 12.

[0051] In combination Figure 1 and Figure 5 understand, in this embodiment, the outer panel lower body 12 includes a side plate 122 and a top plate 121 connected thereto, the top plate 121 is used to engage with the hood 3, the root (i.e. the rear end edge) of the hood 3 can be substantially flush with the rear end edge of the top plate 121, and the top plate 121 is substantially in the horizontal direction or slightly inclined, and the side plate 122 is located on the side of the vehicle and is used to engage with the fender 6. The front end of the outer panel lower body 12 engages with the signal lamp cover 4, and the engagement herein means that the two are adjacent, which can be in contact or can have a certain assembly clearance.

[0052] As Figure 2 , 5 shown, the rear end of the outer panel lower body 12 engages with the lower end of the outer panel upper body 11, the rear end of the side plate 122 of the outer panel lower body 12 has a rearward inclined edge 1221, the inclined edge 1221 is in abutment with the window frame 5 of the quarter window a of the vehicle, and the rear end of the top plate 121 of the outer panel lower body 12 has a notch 12a, which matches the outer peripheral wall of the lower end of the outer panel upper body 11, and Figure 2 , 5 It can be seen that the rear end of the top plate 121 forms a substantially V-shaped notch 12a, the two sides of the notch 12a are a first side 1211 and a second side 1212, the first side 1211 and the second side 1212 wrap around the outer peripheral wall of the outer panel upper body 11, Figure 5In this configuration, the second side 1212 also has a certain curvature to match the corresponding part of the outer peripheral wall of the upper body 11 of the outer trim panel, thus forming a better connection with the upper body 11 of the outer trim panel. At this time, the retaining foot 12.1 can be set at the rear end of the side plate 122 of the lower body 12 of the outer trim panel, such as... Figure 5 As shown.

[0053] Continue to refer to Figure 5 In this embodiment, the lower body 12 of the exterior trim panel is also provided with two clips, namely clip 12.3 and clip 12.4. The lower body 12 of the exterior trim panel can be positioned and engaged with the vehicle body through these two clips, which facilitates assembly. Finally, it can be fastened and fixed by fasteners. The fasteners can be... Figure 5 Bolt 12.2 is shown in the diagram. The two clips are located at the front and rear ends of the side plate 122 of the lower body of the exterior trim panel 12, respectively. This allows for pre-positioning in the front-rear direction before tightening by bolt 12.2. Corresponding insertion holes are provided on the body body at the positions corresponding to clips 12.3 and 12.4. It can be seen that the position of the clips is not limited to this, and one or more clips can also be provided.

[0054] We can continue to combine Figure 5 and refer to Figures 7-10 understand, Figure 7 for Figure 2 Top view of the lower part of the interior and exterior trim panels at position 12; Figure 8 for Figure 7 A schematic diagram of the CC region; Figure 9 for Figure 7 A schematic diagram of the DD region; Figure 10 for Figure 1 A schematic diagram of the A-pillar exterior trim structure 1 installed on the vehicle body from another perspective.

[0055] In this embodiment, the lower body 12 of the exterior trim panel also includes a mounting part 123, which is connected to the rear end edge of the top plate 121. After assembly, the mounting part 123 is located inside the upper body 11 of the exterior trim panel. Figure 7 As you can see, the inner bifurcated portions of the V-shaped rear ends of the mounting section 123 and the top plate 121 connect. For example... Figure 5 As shown, the mounting part 123 is equipped with bolts 12.2, which can be fixed to the vehicle body, as detailed below. Figure 8 As shown, a mounting bracket 8 can be welded from the inner side panel of the vehicle body. The mounting bracket 8 has mounting holes, and bolts 12.2 can be inserted into the mounting holes for fastening.

[0056] like Figure 8As shown, the mounting hole of the mounting bracket 8 of the vehicle body is a waist-shaped hole 8a, the length dimension D2 of the waist-shaped hole 8a is greater than the diameter of the bolt 12.2, the bolt 12.2 can be inserted into the waist-shaped hole 8a and fastened, before being fixed, the distance between the underbody 12 of the outer panel and the hood 3 can be adjusted by adjusting the position of the bolt 12.2 in the waist-shaped hole 8a, so that the surface difference D3 of the underbody 12 of the outer panel and the hood 3 is controllable. Figure 8 In the embodiment, the direction of the length dimension D2 is perpendicular to the width direction, and the bolt 12.2 is arranged obliquely relative to the vertical direction, at this time, when the position of the bolt 12.2 is adjusted along the length direction, the height of the underbody 12 of the outer panel can be finely adjusted, so as to change the surface difference D3 of the underbody 12 of the outer panel and the hood 3.

[0057] In addition, as shown in Figure 5 , 10 The mounting portion 123 also has a matching surface 1231, which can be interference-fitted with the front windshield 7 of the vehicle, so as to further ensure the reliability of the connection between the underbody 12 of the outer panel and the vehicle body. As shown in Figure 5 , the mounting portion 123 includes a downward bottom surface, the bolt 12.2 is located on the bottom surface of the mounting portion 123, and the mounting portion 123 also has a matching surface 1231 facing the rear side of the front windshield 7. A soft rubber layer can be arranged on the matching surface 1231, which can be bonded to the front windshield 7 while being interference-fitted, of course, it can also be a rubber cushion structure, so as to avoid damaging the front windshield 7 when being interference-fitted, and also ensure the interference-fitting effect.

[0058] The embodiment also provides a vehicle including an A-pillar and an A-pillar outer panel structure 1 as described in the above embodiment, which has the same technical effects as the A-pillar outer panel structure 1 described above, and will not be described again.

[0059] The principles and implementation modes of the present application are described by using specific examples in the present application, and the above description of the embodiments is only used to help understand the method of the present application and its core idea. It should be pointed out that, for ordinary skilled in the art, without departing from the principles of the present application, the present application can be improved and modified in several ways, and these improvements and modifications also fall within the protection scope of the claims of the present application.
