A type of vehicle splash guard mudguard

Abstract

A vehicle splash-proof mudguard includes a front fender and an extension plate fixedly installed at the rear of the front fender. The front fender has mounting holes that can be matched with vehicle body structural connectors for quick positioning and installation on the vehicle body structure. Both the front fender and the extension plate have multiple inwardly protruding splash-proof deflector tubes on their inner surfaces. The splash-proof deflector tubes are hollow tubular structures with a beveled cut edge at the free end that decreases in length from top to bottom. A slit of a predetermined width is formed on the shorter side of the tube wall with the beveled cut edge. This vehicle splash-proof mudguard is a two-piece combined structure. The splash-proof deflector tubes formed on the inner surfaces of the front fender and the extension plate can absorb water vapor as the wheels rotate. The water vapor slides down the inner wall of the splash-proof deflector tubes, effectively suppressing the formation of rain and fog on the sides and rear of the wheels, ensuring the visibility safety of overtaking vehicles.

Description

Technical Field

[0001] This utility model relates to a vehicle anti-splash mudguard. Background Technology

[0002] Mudguards are accessories installed near the tires of a vehicle. They are usually fixed to the vehicle body structure with fasteners and wrap around the rear side of the wheel in a ring shape. When the vehicle is driving at high speed in the rain or passing through areas of standing water, the mudguards can effectively prevent water and dirt from being splashed onto the vehicle body due to centrifugal force, thus avoiding pollution of the vehicle body.

[0003] Existing water deflectors and mudguards are generally made of plastic. After injection molding and demolding to obtain the finished product of the set shape, the inner surface of the water deflector and mudguard (the side that is close to the tire surface after installation) is generally smooth. The smooth inner wall is prone to splashing of droplets on the tire due to airflow entrapment. This manifests as a diffused rain mist forming behind and to the side of the tire. Large passenger and freight vehicles have larger tire sizes, and the area of ​​the rain mist formed during high-speed driving is also larger. When small family cars are overtaking large vehicles on highways, drivers may experience a brief visual blur, often leading to accidents due to misjudging the lateral distance between them and large vehicles.

[0004] This solution arose from the need to improve and upgrade the structure of existing water-blocking and mud-blocking plates. Utility Model Content

[0005] To address the shortcomings mentioned above, this utility model provides a vehicle splash guard and mudguard.

[0006] To achieve the above objectives, this utility model provides a vehicle anti-splash mudguard, including a front baffle and an extension plate fixedly installed at the rear of the front baffle. The front baffle is provided with mounting holes that can cooperate with the vehicle body structure connectors for quick positioning and installation on the vehicle body structure. The inner surfaces of the front baffle and the extension plate are provided with multiple inwardly protruding anti-splash deflector tubes. The anti-splash deflector tubes are hollow tubular structures. The free end of the hollow tube has a slanted cut edge with a decreasing length from top to bottom. A slit of a set width is formed on the shorter side of the hollow tube with the slanted cut edge.

[0007] As a further improvement to the solution, the rear of the front baffle has a first overlapping portion, and the front of the extension plate has a second overlapping portion. The first overlapping portion is machined with a plurality of connecting holes for screws to pass through, and the second overlapping portion is formed with a screw seat for screws to be screwed in. The screw seat is positioned corresponding to the connecting holes.

[0008] As a further improvement to the solution, there are five connecting holes, which are evenly spaced along the long side of the first overlapping part.

[0009] As a further improvement to the solution, the first overlapping part is further provided with three to five positioning posts between two adjacent connecting holes. The positioning posts have a circular cross-section. The second overlapping part is provided with positioning tubes for insertion and mating with the positioning posts.

[0010] As a further improvement to the solution, the positioning tube has an elongated cross-section, the short side dimension of the positioning tube matches the positioning post, and the long side dimension of the positioning tube is 1.2 to 1.5 times the diameter of the positioning post.

[0011] As a further improvement to the solution, the outer walls of two adjacent positioning tubes are connected to each other by connecting ribs.

[0012] As a further improvement to the design, the front baffle is made of rigid plastic, and the extension plate is made of soft silicone material.

[0013] As a further improvement to the solution, the front baffle includes an arc-shaped main panel and side panels integrally connected to the left and right sides of the main panel. The side panel located on the inner side is also machined with a notch to facilitate the distinction between the inner and outer sides during installation.

[0014] The advantages of this utility model over the prior art are as follows: This vehicle splash-proof mudguard has a two-piece combined structure. By selecting an extension plate of appropriate length, it can meet the needs of tires and rims of a certain size range. Splash-proof deflector tubes are formed on the inner side of the front mudguard and the extension plate, which can absorb the water vapor as the wheel rotates. The water vapor slides down along the inner wall of the splash-proof deflector tube, effectively suppressing the formation of rain and fog on the side and rear of the wheel, ensuring the visibility safety of overtaking vehicles. This vehicle splash-proof mudguard is particularly suitable for use on large passenger and freight vehicles. Attached Figure Description

[0017] like Figures 1-5As shown in the figure, a vehicle splash guard and mudguard of this utility model includes a front baffle 1 and an extension plate 2 fixedly installed at the rear of the front baffle 1. The front baffle 1 is provided with mounting holes 11 that can cooperate with the vehicle body structure connectors for quick positioning and installation on the vehicle body structure. In the figure, there are two mounting holes 11, but multiple mounting holes 11 can be provided, and their shapes can also be different, as long as the requirements for stable installation of the front baffle 1 on the vehicle body structure are met. The inner sides of the front baffle 1 and the extension plate 2 are provided with multiple inwardly protruding splash deflector tubes 3. The splash deflector tubes 3 are hollow tubular structures. The free end has a beveled edge 31 whose length decreases from top to bottom. A slit 32 of a predetermined width is formed on the shorter side of the hollow tube with the beveled edge 31. The rear of the front baffle 1 has a first overlapping portion 12, and the front of the extension plate 2 has a second overlapping portion 21. The first overlapping portion 12 has multiple connecting holes 121 for screws to pass through, and the second overlapping portion 21 has screw seats 211 for screws to be screwed in. The screw seats 211 correspond to the positions of the connecting holes 121. The front baffle 1 and the extension plate 2 are quickly connected by overlapping first and then screwing in. The number of connecting holes 121... There are five connecting holes 121, which are evenly spaced along the long side of the first overlapping portion 12. Between adjacent connecting holes 121, the first overlapping portion 12 also forms three to five positioning posts 122, each with a circular cross-section. The second overlapping portion 21 forms positioning tubes 212 for insertion and mating with the positioning posts 122. The positioning tubes 212 have an elongated cross-section, with their short side matching the positioning post 122, and their long side being 1.2 to 1.5 times the diameter of the positioning post 122. The mating between the positioning posts 122 and the positioning tubes 212 enables the front baffle 1 to overlap with the extension plate 2. Before initial positioning, the front baffle 1 and the extension plate 2 can move slightly in the width direction, which is convenient for position adjustment when tightening screws; the outer walls of the two adjacent positioning tubes 212 are connected to each other by connecting ribs, which plays a role in local structural reinforcement; the front baffle 1 is made of hard plastic and the extension plate 2 is made of soft silicone material; the front baffle 1 includes an arc-shaped main panel and side panels 13 integrally connected to the left and right sides of the main panel. The inner side panel 13 is also machined with a notch 131 to facilitate the distinction between the inner and outer sides during installation. During installation, the side with the notch 131 is installed closer to the inner side of the tire.

[0018] The vehicle's splash guard and mudguards are a two-piece composite structure. By selecting an extension plate of appropriate length, they can accommodate tires and rims of a certain size range. Splash deflectors are formed on the inner sides of the front fender and extension plate, which can absorb the water vapor as the wheels rotate. The water vapor slides down the inner wall of the splash deflector, effectively suppressing the formation of rain and fog on the sides and rear of the wheels, ensuring the visibility safety of overtaking vehicles. The vehicle's splash guard and mudguards are particularly suitable for use on large passenger and freight vehicles.

[0019] For practical use, in order to facilitate understanding of this utility model, the following description is provided in conjunction with the accompanying drawings: like Figure 6 As shown, when the wheel rotates at high speed, it causes the droplets to undergo centrifugal motion. The flung droplets collide and strike the anti-splash tube, resulting in a loss of kinetic energy. At the same time, most of the droplets enter the inner side of the anti-splash tube through the narrow slits and slide down the inner wall of the anti-splash tube due to their own weight. The collision causes a significant loss of kinetic energy. Meanwhile, the anti-splash tube restricts the splashing of droplets to the outside of the tire, preventing the formation of obvious rain and fog on the outside and rear of the tire. This ensures clear visibility for the driver when overtaking and guarantees driving safety.

[0020] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
