TECHNICAL FIELD

[0001] The present application relates to the technical field of passenger car parts, in particular to a passenger car internal wheel cover aluminum profile. BACKGROUND

[0002] With the development of urban public transportation, low-floor and low-chassis passenger car designs are becoming more and more popular. Although this design is convenient for passengers to get on and off the bus, it also leads to the exposure of the wheel contour inside the passenger car. The exposed wheel contour not only affects the appearance of the car, but also poses a safety hazard, and effective protection and decoration measures need to be taken.

[0003] The existing wheel cover protection device adopts a split structure, which is complex to install, and the exposed fixing screws affect the appearance, and the edges are easily damaged by knocking, the floor leather is not firmly fixed, and the service life is short.

[0004] Therefore, the skilled person in the art provides a passenger car internal wheel cover aluminum profile to solve the problems raised in the background art. SUMMARY

[0005] In view of the deficiencies of the prior art, the present application provides a passenger car internal wheel cover aluminum profile, which solves the problems of complex installation, poor appearance, and poor protection effect of the existing wheel cover.

[0006] To achieve the above purpose, the following technical solutions are adopted: A passenger car internal wheel cover aluminum profile, comprising a main profile, the main profile is integrally extruded by aluminum alloy, the cross section of the main profile comprises a clamping groove part, a supporting part and a decorative part, the clamping groove part is provided with a clamping groove for fixing the floor leather, the supporting part is connected with the body of the passenger car, and the decorative part forms the outer contour of the wheel cover. Through the above technical scheme, the integrally extruded design ensures the overall strength and precision of the profile, and the structure of the clamping groove part, the supporting part and the decorative part is clear, which not only ensures the firmness of installation, but also takes into account the appearance.

[0007] Further, the main profile can be provided with a straight line segment at both ends, the straight line segments are connected into a continuous ring structure by a fan-shaped cutting and folding process, the fan-shaped cutting and folding process is that the connection angle is calculated in advance, the excess fan-shaped part is punched off at the end of the straight line segment by using a stamping die, and then folded and jointed to make no gap after folding. Through the above technical scheme, by calculating the angle and accurately punching off the fan-shaped part, the geometric size of the profile after bending and folding can be ensured to be accurate, the tight and seamless connection at the joint is realized, the gap caused by segmented splicing is eliminated, the overall appearance and structural strength of the wheel cover are significantly improved, the on-site installation process is simplified, and the assembly efficiency is improved.

[0008] Further, the support part is provided with a mounting hole, and a self-tapping screw is arranged in the mounting hole to fix the passenger car body; By the above technical scheme, the self-tapping screw fixing mode is convenient to install, and a nut does not need to be pre-buried, thereby reducing installation cost and difficulty.

[0009] Further, the surface of the decoration part is provided with a decoration pattern, and the decoration pattern matches the interior decoration style of the passenger car. By the above technical scheme, the design of the decoration pattern makes the profile better integrate into the interior decoration of the whole vehicle, and visual aesthetics is improved.

[0010] Further, the wall thickness of the main profile is 2-3 mm. By the above technical scheme, the reasonable wall thickness design meets the structural strength requirement and realizes the lightweight target, and conforms to the lightweight trend of the passenger car.

[0011] Further, the slot width of the clamping slot is less than the slot bottom width, and a anti-falling structure is formed. By the above technical scheme, the anti-falling structure design effectively prevents the floor covering from accidentally falling off, and use reliability is improved.

[0012] Further, the main profile is made of 6063 aluminum alloy material. By the above technical scheme, the 6063 aluminum alloy has excellent hot extrusion performance and good corrosion resistance, is easy to extrude into a complex cross-section structure, can meet the demand of product lightweight, and at the same time, ensures that the profile has sufficient mechanical strength and surface treatment quality, and prolongs the service life of the wheel cover.

[0014] 2. The application provides a passenger car interior wheel cover aluminum profile, which is firmly fixed to the floor covering and completely conceals the screw through the ingenious clamping slot structure and hidden fixing scheme, realizes simple and beautiful appearance and reliable protection performance, and effectively improves the durability of the product, the quality of the passenger car interior, and the convenience of later maintenance.

[0015] 3. The application provides a passenger car interior wheel cover aluminum profile, which is integrally connected at both ends to form a ring structure, so that on-site splicing is not needed during installation, the assembly process is fast and convenient, the installation efficiency is improved, and the integrity and aesthetics of the appearance of the wheel cover are ensured.
