TECHNICAL FIELD
[0001] The utility model belongs to the technical field of passenger car wheel cover, especially relate to a spliced wheel cover guard plate for passenger car. BACKGROUND
[0002] With the population growth, the public transport pressure of each place is more and more big, in order to improve the public transport efficiency, the pure electric passenger car manufacturer designs low floor bus, this car type not only improves the volume of passenger car, also improves the barrier-free and inclusiveness of public transport, such as the convenience of the old and the disabled, also suitable for the use of wheelchair and baby carriage.
[0003] The front wheel passageway floor of low floor bus is generally designed to be low and wide, and the space is released to the car as much as possible. This structure will squeeze the pipeline layout space designed on the chassis outside the vehicle. In addition to the need to set the wheel cover framework at a low position, the pipelines to be arranged are designed on the inner vertical surface of the front wheel cover. Therefore, if the traditional welded wheel cover guard plate is used for the bus, the front wheel cover framework and the bracket at the related position are relatively easy to appear serious corrosion problems after a certain period of operation. Specifically, the traditional welded wheel cover guard plate uses a steel plate, which is fixed by welding. The steel plate and the wheel cover framework cannot be completely electrophoresed, so the gap between the steel plate and the wheel cover framework after welding is sealed by glue. When there are many gaps, it is difficult to ensure complete sealing. At the same time, compared with the service life of the whole vehicle, the sealing glue has the risk of premature failure. Therefore, the steel plate and the wheel cover framework are easy to appear serious corrosion and damage at the welding gap, and mud, sand and stones will splash from the gap to the steel plate, pipelines, shock absorbers and sound insulation materials and other elements. In addition, since the steel plate and the wheel cover framework are welded together, it is not convenient to disassemble, replace and maintain after damage. SUMMARY
[0004] The utility model aims at providing a spliced wheel cover guard plate for passenger car to solve the technical problems in the background art.
[0005] The spliced wheel cover guard plate for passenger car comprises:
[0006] The front guard plate is connected as a three-fold structure through a front top fold, a front middle fold and a front bottom fold. The front top fold is provided with a front top connecting hole in an array. The front bottom fold is provided with a front bottom connecting hole. The front bottom is fixedly connected with a front bottom bracket through a screw. The front bottom bracket is used for fixedly connecting to the wheel cover framework.
[0007] The rear skid plate is a four-fold structure consisting of a rear top fold, a rear middle fold, a rear middle fold, and a rear bottom fold. The rear top fold has rear top connection holes arranged in a row. The rear top connection holes are aligned and fixed with the front top connection holes by a set of top screws. At this time, the outermost part of the rear top fold overlaps and fits with the outermost part of the front top fold to prevent mud, water, and gravel from splashing in through the gap between the rear and front top folds. The top screw set fixes a top bracket, which is used to fix and connect to the wheel arch frame so that the rear skid plate and the front skid plate can cover the upper part of the wheel to block mud, water, and gravel. The rear bottom fold has a rear bottom connection hole, which is fixed and connected to a rear bottom bracket by screws. The rear bottom bracket is used to fix and connect to the wheel arch frame.
[0008] Based on the above technical solution, the present invention achieves the following beneficial effects:
[0009] 1. Because the top screw assembly of the rear bottom folding surface is aligned with the front top screw assembly of the front skid plate, the rear skid plate and the front skid plate form a wheel cover that can cover the upper part of the wheel. The top screw assembly is installed on the wheel cover frame through a fixed top bracket. The front bottom screw assembly of the front skid plate is fixedly installed on the wheel cover frame through a fixed front bottom bracket. The rear bottom screw assembly of the rear skid plate is fixedly installed on the wheel cover frame through a fixed rear bottom bracket. Therefore, when the wheel cover is damaged, the damaged part can be disassembled and repaired, thereby improving the convenience of maintenance.
[0010] 2. Since the top screw assembly of the rear top connecting hole of the rear bottom fold is aligned and fixed with the front top connecting hole of the front guard plate, the outermost part of the rear top fold overlaps and fits with the outermost part of the front top fold. Therefore, it can effectively prevent mud, water and sand from splashing into the splicing gap between the front guard plate and the rear guard plate and causing damage to the components outside the wheel arch guard plate.
[0011] 3. Since mud, water, sand and gravel will not splash in through the joint between the front and rear guard plates, there is no need to apply sealant to the joint. At the same time, it is only necessary to apply an anti-rust coating or perform electrophoresis on the wheel guard plate near the wheel, thereby effectively reducing the manufacturing cost.
[0012] 4. Since there is no need to apply sealant to the joint between the front and rear skid plates, there is no need to worry about the sealant failing and causing corrosion of the wheel arch frame and surrounding components. At the same time, it is also easy to separate the front and rear skid plates during disassembly.
[0013] 5. Because the front skid plate has a three-fold structure and the rear skid plate has a four-fold structure, the front and rear skid plates can be spliced together to fit the arc contour of the wheel arch frame, while increasing the structural strength.
