Description

Technical Field

[0001] The present application relates to the technical field of automotive trim parts, and particularly relates to a wheel arch trim panel and a vehicle. Background Art

[0002] With the rapid development of automobiles, wheel arch trim panels are increasingly applied to models such as SUVs and MPVs. Since the wheel trim panels can be processed by various techniques to achieve different effects such as painting, leather texture, and electroplating, they can not only protect the vehicle fenders from erosion by sediment and the like, reduce the corrosion of sheet metal paint, but also achieve variable shapes, reduce the drag coefficient, and at the same time increase the aesthetics and perception of the vehicle.

[0003] In the related art, the conventional positioning structure of the wheel arch trim panel is as follows: the main positioning is close to the corner position at the rear end of the fender. The top end of the wheel arch trim panel is the secondary positioning. The matching area between the wheel arch trim panel and the bumper is limited in the normal direction of the arc edge. A buckle is provided at the position of the matching gap between the wheel arch trim panel and the bumper in the height direction for Y-direction limiting. The above positioning strategy will cause a V-shaped gap to form in the matching area between the wheel arch trim panel and the front door trim panel, and the gap surface difference with other surrounding parts is unstable, affecting the delicate perception of the whole vehicle. Summary of the Utility Model

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the following will clearly and completely describe the technical solutions in the embodiments of this application with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, rather than all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of protection of this application.

[0033] In related technologies, with the rapid development of automobiles, wheel arch trim panels are increasingly applied to models such as SUVs and MPVs. Since the wheel trim panels can be processed by various techniques to achieve different effects such as painting, leather texture, and electroplating, they can not only protect the vehicle fenders from erosion by sediment and reduce the corrosion of sheet metal paint, but also achieve diverse shapes, reduce the wind resistance coefficient, and at the same time increase the aesthetics and perception of the vehicle.

[0034] However, the conventional positioning structure of the wheel arch trim panel is as follows: the main positioning is close to the corner position at the rear end of the fender, the topmost part of the wheel arch trim panel is the secondary positioning, the matching area between the wheel arch trim panel and the bumper is limited in the normal direction of the arc edge, and a buckle is arranged at the position of the fitting gap between the wheel arch trim panel and the bumper in the height direction for Y-direction limiting. The above positioning strategy will cause a V-shaped gap to form in the matching area between the wheel arch trim panel and the front door trim panel, and the gap surface difference with other surrounding parts is unstable, affecting the refined perception of the whole vehicle.

[0035] To solve the above problems, this application provides a wheel arch trim panel and a vehicle, which can solve or improve the problem of poor stability of the fitting gap surface difference between the wheel arch trim panel and the surrounding parts, so as to improve the refined perception of the whole vehicle.

[0036] The following will describe the embodiments of this application in conjunction with Figures 1 to 5 , to describe the embodiments of this application.

[0037] According to an embodiment of this application, on the one hand, a wheel arch trim panel is provided, as shown in Figure 1 and Figure 2 , which includes a trim panel assembly 1. The trim panel assembly 1 includes a wheel arch lower trim part 101 and an arc part 102 that are connected to each other; wherein, as shown in Figure 5 , the wheel arch lower trim part 101 is adapted to be connected to the body assembly or the fender assembly 3 by a buckle, and is adapted to perform a gap surface difference fit with the skirt panel assembly. As shown in Figure 3 , a main positioning part 1011 is arranged on the wheel arch lower trim part 101, which is adapted to form X-direction and Z-direction positioning for the trim panel assembly 1. Specifically, the main positioning part 1011 is a positioning pin or a main positioning insert piece, with a unilateral limit of 0.1 mm; as shown in Figure 2As shown, the arc portion 102 is successively adapted to be connected to the fender assembly 3 and the bumper assembly 2 by snap fasteners in a direction away from the wheel arch lower trim portion 101, and a clearance and flushness fit is performed. A plurality of secondary positioning portions 1021 are provided on the arc portion 102. Specifically, the secondary positioning portions 1021 are secondary positioning pins, and the plurality of secondary positioning portions 1021 are arranged at intervals along the arc direction of the arc portion 102, and are adapted to position the arc portion 102 in the normal direction of the arc of the arc portion 102, with a 0.1 mm limit on one side and a 1 mm allowance on one side in the arc direction.

[0038] It should be noted that, as Figure 2 shown, the above X-direction, Y-direction, and Z-direction refer to the X-direction, Y-direction, and Z-direction of the vehicle coordinate system. Of course, in the vehicle coordinate system, the X-direction refers to the front-rear direction of the vehicle, the Y-direction refers to the width direction of the vehicle, and the Z-direction refers to the height direction of the vehicle.

[0039] It should be explained that the above skirt panel assembly can be a separately manufactured plastic skirt panel assembly, which is installed on the vehicle body through snap connectors, or can be a "skirt panel assembly" made of sheet metal.

[0040] It is worth noting that when the wheel arch trim is the front wheel arch trim of the vehicle, the arc portion 102 is successively adapted to be connected to the front fender assembly 3 and the front bumper assembly 2 by snap fasteners; when the wheel arch trim is the rear wheel arch trim of the vehicle, the arc portion 102 is successively adapted to be connected to the rear fender assembly 3 and the rear bumper assembly 2 by snap fasteners.

[0041] In this embodiment, as Figure 1 、 Figure 2 and Figure 5 shown, by providing the main positioning portion 1011 on the wheel arch lower trim portion 101 and arranging a plurality of secondary positioning portions 1021 at intervals along the arc direction of the arc-shaped trim plate 105, the main positioning portion 1011 can accurately position the wheel arch lower trim portion 101 relative to the skirt panel assembly in the X-direction and Z-direction. One of the secondary positioning portions 1021 close to the main positioning portion 1011 can prevent the mating portion of the skirt panel assembly from rotating around the main positioning portion 1011 because its limiting direction is basically the same as the rotation direction of the skirt panel around the main positioning portion 1011, ensuring that the clearance and flushness with the skirt panel assembly meet the DTS requirements. Specifically, the matching clearance and flushness between the wheel arch trim and the skirt panel assembly can meet within a range of 0.5 mm; at the same time, the plurality of secondary positioning portions 1021 are arranged at intervals along the arc direction of the arc portion 102, and are adapted to position the arc portion 102 in the normal direction of the arc of the arc portion 102, thereby preventing the arc portion 102 from sinking in the Z-direction to ensure the clearance and flushness of the arc portion 102 in cooperation with the bumper assembly 2, the vehicle body assembly, or the fender assembly 3.

[0042] In one embodiment, as Figure 4As shown, a limiting portion 1022 is provided at the end of the arc portion 102 away from the lower wheel arch trim portion 101. The limiting portion 1022 is adapted to cooperate with the bumper assembly 2 to form Y-direction and Z-direction limits for the trim panel assembly 1.

[0043] Specifically, a limiting portion 1022 is provided at the end of the arc portion 102 away from the lower wheel arch trim portion 101, which means that the limiting portion 1022 can be provided on the end face or side face of the end of the arc portion 102 away from the lower wheel arch trim portion 101.

[0044] In this embodiment, by providing the limiting portion 1022 at the end of the arc portion 102 away from the lower wheel arch trim portion 101, Y-direction and Z-direction limits are applied to the trim panel, so as to ensure the clearance surface difference between the end of the arc portion 102 away from the lower wheel arch trim portion 101 and the bumper assembly 2. Specifically, the Y-direction surface difference between the wheel arch trim panel and the bumper is ensured, and the clearance thereof also meets the requirement of the flatness difference within the range of 0.5 mm.

[0045] In one embodiment, as Figure 2 shown, the wheel arch trim panel further includes a connecting portion 103. Specifically, the connecting portion 103 is a buckle installed on the wheel arch trim panel through a buckle seat, and more specifically, a D-shaped buckle, etc.; a plurality of connecting portions 103 are provided, which are respectively provided on the lower wheel arch trim portion 101 and the arc portion 102, and are adapted to be snap-connected along the Y-direction with the snap holes on the vehicle body assembly, the corresponding snap holes on the fender assembly 3, and the snap holes on the bumper assembly 2. Among them, a connecting portion 103 is provided around each sub-positioning portion 1021.

[0046] It should be noted that a connecting portion 103 is provided around each sub-positioning portion 1021, which means that a connecting portion 103 is provided beside each sub-positioning portion 1021. Usually, the connecting portion 103 and the sub-positioning portion 1021 are both provided on an installation table, and the form of the installation table is usually a doghouse, etc.

[0047] In this embodiment, by providing a connecting portion 103 around each sub-positioning portion 1021 and applying Y-direction limit to the wheel arch trim panel through the connecting portion 103, it is ensured that each sub-positioning portion 1021 is inserted into its corresponding sub-positioning hole in place, and the positioning accuracy of each sub-positioning portion 1021 is ensured, thereby further improving the accuracy and consistency of the clearance surface difference between the wheel arch trim panel and the surrounding parts.

[0048] In one embodiment, as Figure 4As shown, the limiting part 1022 includes a first limiting member 10221 and a second limiting member 10222. The first limiting member 10221 is arranged at the end of the arc part 102 away from the wheel arch lower trim part 101 and is adapted to be connected to the bumper assembly 2 for Y-direction limiting; the second limiting member 10222 is arranged at the part of the arc part 102 close to the first limiting member 10221 and is adapted to be connected to the bumper assembly 2 for Z-direction limiting.

[0049] It should be noted that the forms of the first limiting member 10221 and the second limiting member 10222 can be any structure capable of limiting, such as a single-sided hook with a limiting rib, an insert piece with a limiting rib, etc., as long as the limiting in the specified direction can be achieved.

[0050] In this embodiment, the limiting part 1022 is set as the first limiting member 10221 and the second limiting member 10222, which is convenient for manufacturing and the installation of the wheel arch trim panel, will not cause damage to the limiting, and improves the accuracy of the limiting.

[0051] In a specific embodiment, such as Figure 4 and Figure 5 As shown, a plurality of first limiting members 10221 are arranged at intervals in the X direction. Specifically, the number of the first limiting members 10221 is 2 to 3, preferably 2; and / or, the first limiting member 10221 is an insert piece extending in the Z direction, and a first limiting rib is arranged on the insert piece. The insert piece is adapted to be inserted into a slot on the bumper lower body in the bumper assembly 2, and the first limiting rib is adapted to cooperate with the slot on the bumper lower body for Y-direction limiting, with a single-sided limit of 0.1 mm. Specifically, the number of the first limiting ribs is not less than 2 and is arranged in parallel at intervals; and / or, the second limiting member 10222 is a hook, and a second limiting rib is arranged on the hook. The hook is adapted to be clamped in a slot on the bumper upper body in the bumper assembly 2, and the second limiting rib is adapted to cooperate with the slot on the bumper upper body for Z-direction limiting, with a single-sided limit of 0.5 mm. Specifically, the number of the second limiting ribs is not less than 2 and is arranged in parallel at intervals; in this embodiment, the number of the first limiting members 10221 is multiple, which can avoid the over-large opening of the mating part, reduce the strength, and improve the limiting accuracy and strength of the wheel arch trim panel; the first limiting member 10221 is an insert piece with a first limiting rib, and the second limiting member 10222 is a hook, with a simple structure and good limiting effect.

[0052] In an embodiment, such as Figure 2As shown, the arc length between any two adjacent secondary positioning portions 1021 is 300 mm to 450 mm, preferably any one of 300 mm, 310 mm, 320 mm, 330 mm, 340 mm, 350 mm, 360 mm, 370 mm, 380 mm, 390 mm, 400 mm, 410 mm, 420 mm, 430 mm, 440 mm, and 450 mm, and more preferably any one of 300 mm, 350 mm, 400 mm, and 450 mm. Of course, it can also be slightly enlarged or reduced according to specific circumstances. In this embodiment, the arc length between any two adjacent secondary positionings is 300 mm to 450 mm, which can ensure the gap surface difference between the wheel arch trim and the surrounding parts and meet the DTS requirements.

[0053] In one embodiment, as Figure 2 shown, the trim assembly 1 includes a lower wheel arch trim 104, an inner panel 106, and an arc-shaped trim 105. Specifically, both the lower wheel arch trim 104 and the arc-shaped trim 105 are plastic decorative parts with relatively high surface requirements such as painted parts or electroplated parts, and the inner panel 106 is a general injection molded part. The inner panel 106 includes a first connecting portion 1061 and a second connecting portion 1062. The first connecting portion 1061 is welded to the lower wheel arch trim 104 by a solder tab or vibration friction welding, and the second connecting portion 1062 is welded to the arc-shaped trim 105 by a solder tab or vibration friction welding. The main positioning portion 1011 is provided on the first connecting portion 1061, and the limiting portion 1022 and multiple secondary positioning portions 1021 are provided on the second connecting portion 1062. The lower wheel arch trim 104 and the first connecting portion 1061 form the lower wheel arch trim portion 101, and the arc-shaped trim 105 and the second connecting portion 1062 form the arc portion 102.

[0054] In this embodiment, by splitting the wheel arch trim into three parts: the lower wheel arch trim 104, the inner panel 106, and the arc-shaped trim 105, the surfaces of the lower wheel arch trim 104 and the arc-shaped trim 105 can be processed with high quality, such as painting, electroplating, etc., making it suitable for high-end models, improving the refined perception of the vehicle, and meeting the needs of customers.

[0058] In this embodiment, the lower fender trim 104 and the arc-shaped trim 105 are both positioned with the inner panel 106 through the main and secondary positioning pieces, which can ensure the position accuracy between the lower fender trim 104, the arc-shaped trim 105 and the inner panel 106.

[0059] In one embodiment, as Figure 3 shown, a plurality of first limiting bumps 10611 are arranged at intervals on the edge of the first connecting portion 1061 close to the inner circle of the lower fender trim 104, and the plurality of first limiting bumps 10611 form a limit with the inner side surface of the inner circle flanging of the lower fender trim 104; and / or, a plurality of second limiting bumps 10621 are arranged at intervals on the edge of the second connecting portion 1062 close to the inner circle of the arc-shaped trim 105, and the plurality of second limiting bumps 10621 form a limit with the inner side surface of the inner circle flanging of the arc-shaped trim 105; and / or, a plurality of limiting pieces 1053 are arranged at intervals along the arc direction on the arc-shaped trim 105, and the plurality of limiting pieces 1053 are respectively matched with a plurality of limiting grooves on the inner panel 106 and are suitable for performing limiting in the normal direction along the arc of the arc-shaped trim 105; and / or, a limiting piece 1044 is provided on the edge of the inner circle flanging of the lower fender trim 104 opposite to the inner circle flanging of the arc-shaped trim 105, and the limiting piece 1044 is limitedly arranged with the inner surface of the inner circle flanging of the arc-shaped trim 105.

[0060] Specifically, the distance between the first limiting bump 10611 and the inner circumferential flange of the wheel arch lower trim panel 104 is 0.5 mm; the limiting piece 1053 is 0.1 mm on one side in the arc direction, and the distance between the shape-limiting piece 1044 and the inner surface of the inner circumferential flange of the arc-shaped trim panel 105 is 0.2 mm.
