Detailed Description

The present invention will be described in further detail with reference to the following drawings and embodiments:

Example 1

The utility model relates to a fender that splashes is prevented to integral type, for PP-PE material injection molding, including body 2, the integrative suppression structure that splashes that prevents of moulding plastics on body 2's the internal surface, body 2 is equipped with the runner that the surface formation of the suppression structure that splashes the liquid stream that prevents splashing.

One embodiment of an integrated splash guard rear fender and rear extension panel assembly is shown in fig. 1-7. The main structure of the rear mudguard 1 is an arc-shaped body 2, and a side plate with a flange is arranged on one surface of the body 2 corresponding to the outer side of the wheel, and is mainly used for preventing splash liquid from flowing to impact of the side surface. The main structure of the rear lengthened plate 4 is a plate-shaped structure, and the upper part of the rear lengthened plate 4 is connected with the rear mudguard 1 through 6 screws. The inner arc surface of the arc-shaped body 2 of the rear mudguard 1 and the inner surface of the rear lengthened plate 4 are integrally injected with the anti-splash restraining structure in the same form.

As shown in fig. 2, the splash prevention suppression structure is a hollow cylinder distributed in a rectangular array. As shown in fig. 3, 4 and 6, the hollow cylinder is obliquely arranged, and for the rear mudguard, the splashing liquid flow is mainly shown as that the liquid flow is splashed upwards from the ground in the running process of the automobile, so that an included angle is formed between the hollow cylinder and the tangential vertical line of the upward splashing liquid flow, the hollow cylinder is obliquely directed upwards to the wheel and downwards extends along the wheel, and the included angle ranges from 20 degrees to f degrees and is less than or equal to 120 degrees. The edge distance between the adjacent outer ring surface and the outer ring surface of the hollow cylinders arranged in the array is 3mm or more and 30mm or less, the height of the hollow cylinders is 2mm or more and 50mm or less, and the inner diameter of the hollow cylinders, namely the distance between the central point and the side line, is 2mm or more and 30mm or less.

As shown in fig. 3, 4 and 7, the hollow cylinder is provided with an arc notch 5 in the direction opposite to the splashing liquid flow, that is, the outer end surface of the hollow cylinder is an arc end surface, and the arc end surface is formed by cutting off the outer end of the hollow cylinder far away from the body by an arc knife edge. The arc incision 5 is recovered from the top end of the upper half side of the hollow cylinder towards the inner side of the body from the downward and inward arc-shaped knife edge, and the arc incision 5 is stopped at the bottom end face of the lower half side of the hollow cylinder. The included angle between the arc notch 5 and the vertical line is more than or equal to 10 degrees and less than or equal to 80 degrees.

As shown in fig. 2-4 and 7, the hollow cylinder is notched 6 towards the lower half of the proximal end against the splashing liquid stream. The notch 6 is formed by cutting off a plurality of fan-shaped rings by a cutter along the axis of the hollow cylinder, and the notch 6 extends inwards from the outer end surface of the hollow cylinder to the inner surface of the body.

In the embodiment, the inclination angle f is 90 degrees, the edge distance is 10mm, the height c is 30mm, the inner diameter d is 13mm, and the included angle range e between the arc notch and the vertical line is 45 degrees; the lower half side of the hollow cylinder is provided with 5 openings, the lowest end is provided with one opening, and the two sides are symmetrically provided with openings at two sides.

The hollow bulge 3 of the hollow cylinder can also be deformed into a hollow cylinder with the shape of rectangle, square, trapezoid, triangle, hexagon, quincunx and the like. The structure requires the same size and angle as the distribution of the hollow cylinders.

When the automobile rear fender is in operation, the automobile runs in a rainy day or on a water ground (special conditions such as reversing are not considered), the wheels rotate forwards at a high speed to drive liquid flow to throw the fender, for the rear fender, the liquid flow splashes to the opening from bottom to top, the anti-splashing restraining structure opening blocks the liquid flow to play a certain energy-absorbing and shock-proof role, and then the liquid flow downwards flows out along the body downwards along the inclination angle of the cylindrical surface of the hollow cylinder. The opening formed by the arc notch and the notch is beneficial to forming a larger opening space and blocking the arc surface, so that splashing liquid flow is blocked conveniently.

Example 2

Fig. 8 and 9 show an embodiment of an integrated splash-proof front fender and a front elongated plate. This example differs from example 1 in that: the main body structures of the front fender and the rear fender are slightly different. The inclined direction, the arc notch and the notch of the hollow bulge integrally molded on the inner surfaces of the front mudguard and the front lengthened plate are arranged at different positions from those of the rear mudguard.

For the front fender, the splashing liquid flow is mainly shown in the process that the liquid flow is carried away from the wheel to splash forwards and downwards in the advancing process of the automobile, so that the coming direction of the splashing liquid flow is obliquely downwards directed to the front fender from the wheel, the tangential direction of the splashing liquid flow downwards of the hollow bulge forms an included angle with the body, and the range of the inclination angle is more than or equal to 20 degrees and less than or equal to 120 degrees. The corresponding circular-arc cut 5 shown in fig. 8 and 9 is closed upward and inward from the lower end of the hollow protrusion, i.e., the circular-arc cut opens upward. A plurality of gaps 6 are arranged on the upper half side of the hollow bulge. Other parameters of the hollow protrusions were the same as those of example 1.
