Description
Technical Field
[0001] The utility model relates to the field of automobile front fender assemblies, and particularly to an automobile front fender assembly structure. Background Art
[0002] The front fender, as an important part of an automobile, has multiple functions and meanings. As a part of the vehicle body appearance, the front fender has a significant decorative effect. Especially for non-white cars, installing a front fender can bring visual beauty, make the body lines more smooth, and enhance the overall appearance charm of the vehicle. With the development of the concept of automobile personalization, the front fender has also become an option for car owners' customized modifications. By replacing the front fenders of different styles, materials or colors, car owners can meet their personalized needs and make their cars more unique. The wheel hub area is where the vehicle is prone to scratches during use. Installing a front fender can, to a certain extent, protect the wheel hub from minor scratches and reduce vehicle damage. The design of the fender conforms to the principle of fluid mechanics and can, to a certain extent, reduce the wind resistance coefficient, improve the driving stability and fuel economy of the vehicle. The connection between the front fender and the door lower trim usually involves a variety of technologies and processes, and these connection methods are designed to ensure the cleanliness of the vehicle appearance, the stability of the structure, and the safety during driving. The rear end split of the front fender needs to have continuity with the door lower trim. As Figure 1-2 shown, it is a schematic diagram of the connection between the upper and lower outer plates and the inner plate in the prior art. The upper and lower outer plates and the inner plate are used in a form of limit to cooperate and fix. In this way, there is an inconsistency in the surface difference of the split position. The cumulative tolerances of the two outer plates and the inner plate after product board injection molding and welding are inconsistent, resulting in uneven surface differences in the split position gap, and it is easy to appear unsightly problems. Now people pay particular attention to the aesthetics of vehicles.
[0003] Therefore, it is particularly important to design an automobile front fender assembly structure with uniform surface differences in the split position gap between the upper and lower outer plates and the inner plate, consistent front fender appearance, and simple assembly.

[0024] An embodiment of the present utility model provides a structure of an automobile front fender assembly.
[0025] Such as Figure 1-2As shown in the figure, it is a schematic diagram of the connection and installation of the upper and lower outer plates and the inner plate in the prior art. At the connection of the upper outer plate 1 and the lower outer plate 2, there is an inner and outer plate limit rib 3. The upper outer plate 1 and the lower outer plate 2 are in contact and close to each other. At the connection of the upper outer plate 1 and the lower outer plate 2, there is an inner plate 4. The inner plate 4 is provided with inner and outer plate limit rib holes. The inner and outer plate limit rib holes on the inner plate 4 are arranged on the inner and outer plate limit ribs 3 on the upper outer plate 1 and the lower outer plate 2 to achieve the connection and fixation of the upper outer plate 1 and the lower outer plate 2. However, there is a problem that the upper and lower outer plates and the inner plate 4 cannot be properly buckled together, resulting in a vertical difference in the position gap between the upper and lower outer plates, and the upper and lower outer plates are not parallel to each other.
[0026] As Figures 3-7 shown in the figure, it is the connection method of the improved upper outer plate 1 and the lower outer plate 2. The lower outer plate 2 is provided with a buckle 7 and a rib limit plate 8. The upper outer plate 1 is provided with a buckle hole and a rib limit plate hole matching the lower outer plate 2. The upper outer plate 1 and the lower outer plate 2 are fixed to each other by buckling the buckle 7 and the buckle hole and buckling the rib limit plate 8 and the rib line plate hole; the buckle 7 and the buckle hole form a complete buckle structure to fix the upper and lower outer plates. At the same time, the rib limit plate 8 is also provided to enhance the connection stability of the upper and lower outer plates, and the upper and lower buckling of the buckle structure is more reliable and stable. The gap surface difference at the split position between the two outer plates is consistent. Compared with the prior art, it is no longer necessary for the inner plate to cooperate with the upper and lower outer plates to realize the connection and fixation of the upper and lower outer plates. Directly fixing the upper and lower outer plates to each other reduces interference factors and increases the consistency of the gap surface difference at the split position.
[0027] The connection and fixation part of the upper outer plate 1 and the lower outer plate 2 is wrapped with an inner plate 3. The inner plate 3 is arranged to avoid the matching positions of the upper outer plate 1 and the lower outer plate 2. The inner plate 3 plays the role of a protective layer and does not contact the connection structure of the upper outer plate 1 and the lower outer plate 2. At the same time, a number of piercing welding points 5 and buckle anti-loosening structures 6 are arranged on the upper outer plate 1 and the lower outer plate 2 according to certain regulations.
[0028] As Figures 6-7 shown in the figure, the front wheel arch product is made of PP+EPDM-TD20 material. At the same time, the connection part of the upper outer plate 1 and the lower outer plate 2 is connected in the form of a positioning pin of the buckle 7 and the rib limit plate 8. As shown by the C mark, the distance between the buckle 7 and the convenient outer plate is within 20mm. As shown by the B mark, the distance between two buckles 7 is within 80mm. As shown by the F mark, the thickness of the rib limit plate 8 is more than 1.5mm. As shown by the D mark, the buckle clamping amount is 12°. The clamping angle of the buckle 7 is controlled within 10-15°.
[0029] This device is different from the prior art. The prior art uses raised inner and outer plate limit ribs 3 provided on the upper outer plate 1 and the lower outer plate 2 and is installed in cooperation with the hollowed-out inner and outer plate limit rib holes provided on the inner plate. This device uses a snap structure and a rib limit plate positioning pin form to connect and fix the upper outer plate 1 and the lower outer plate 2. Compared with the prior art, it does not require the cooperation of the inner plate 4. At the same time, the snap structure is more convenient and stable to install, and the installation is more convenient and stable through the rib limit plate positioning pin form. It can effectively ensure the consistency of the gap surface difference at the seam position, meet the appearance consistency problem, and the assembly process and the functional ends of the parts are not affected. The process is controllable and the requirements for the part size end are reduced. This device is easy to manufacture and suitable for large-scale industrial production.
[0030] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present utility model. Any reference signs in the claims should not be regarded as limiting the claimed rights.
[0031] In addition, it should be understood that although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
