Description

Technical Field

[0001] This utility model relates to the field of vehicle mudguards, and more particularly to a vehicle mudguard made of a novel material. Background Technology

[0002] Vehicle mudguards are important components installed behind the wheels to block mud, rainwater, and flying gravel. Traditional mudguards are mostly made of metal (such as steel plates and aluminum alloys) or hard plastics (such as PP and ABS). Although these materials have a certain strength and durability, they are not suitable for the use of special vehicles in extreme weather conditions, such as high temperatures of up to 85°C and low temperatures of -45°C, and in places where there may be chemical solvents.

[0003] Therefore, those skilled in the art have provided a novel material for vehicle mudguards to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a new type of vehicle mudguard. Through the setting of the adjustment mechanism, by pressing the positioning post to compress the damping spring into the interior of the mounting groove, the movable plate is pulled to the appropriate position, and then the positioning post is aligned with the positioning hole. Then, the positioning post is locked into the interior of the positioning hole by the elastic force of the damping spring, so that the vehicle mudguard can effectively adapt to vehicles with different chassis heights.

[0005] To achieve the above objectives:

[0006] This utility model provides a new type of vehicle mudguard, including a mudguard mechanism. The mudguard mechanism includes a fixed plate and a movable plate. The outer walls of the fixed plate and the movable plate are provided with a covering mechanism. The covering mechanism includes an engineering plastic alloy provided on the front outer wall of the fixed plate and the movable plate, and a fiberglass material provided on the rear outer wall of the fixed plate and the movable plate.

[0007] Both the fixed plate and the movable plate are equipped with an adjustment mechanism. The adjustment mechanism includes mounting grooves on both sides of the upper part of the movable plate. A sliding rod is installed inside the mounting groove. The sliding rod is fitted with a damping spring and a positioning post. Positioning holes are opened on both outer walls of the fixed plate.

[0008] The above technical solution effectively solves the problem that existing technologies cannot meet the usage conditions in extreme environments.

[0009] Furthermore, mounting plates are fixedly connected to both sides of the upper surface of the fixing plate;

[0010] The above technical solution allows for easier installation of the mudguard via the provided mounting plate.

[0011] Furthermore, the fixed plate has a movable groove inside, and the movable plates slide inside the movable groove;

[0012] The above technical solution allows the movable plate to slide more easily through the set movable groove, and also makes it easier for the positioning pin to be inserted into the positioning hole.

[0013] Furthermore, the damping spring is sleeved on the side of the slide rod near the middle of the movable plate, and the positioning posts slide on the side of the slide rod away from the damping spring. The positioning posts have a storage cavity inside.

[0014] The above technical solution allows for easier resetting of the positioning post using a damping spring, and the storage cavity allows for the storage of one end of the slide rod when the positioning post moves.

[0015] Furthermore, a silicone pad is fixedly connected to the outer wall of the positioning post on the side away from the movable plate;

[0016] The above technical solution effectively improves the pressing feel of the positioning post by using the silicone pad.

[0017] Furthermore, all the positioning pins are engaged with positioning holes;

[0018] The above technical solution allows for a more convenient fixation of the height of the movable plate using positioning posts and positioning holes.

[0019] This utility model has the following beneficial effects:

[0020] 1. This utility model proposes a new type of vehicle mudguard made of a novel material. Through an adjustment mechanism, the positioning pin is pressed to compress the damping spring into the mounting groove. Then, the movable plate is pulled to a suitable position, and the positioning pin is aligned with the positioning hole. The positioning pin is then engaged in the positioning hole by the elastic force of the damping spring, thereby enabling the vehicle mudguard to effectively adapt to vehicles with different chassis heights.

[0021] 2. The present invention proposes a novel vehicle mudguard made of engineering plastic alloy and fiberglass. The fiberglass enhances the mudguard's performance under extreme conditions and effectively improves its corrosion resistance. The engineering plastic alloy further enhances both its corrosion resistance and impact resistance. Attached Figure Description

Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] This utility model provides a specific implementation method:

[0034] Reference Figure 1 , Figure 4 and Figure 5 :

[0035] A new type of vehicle mudguard made of a novel material includes a mudguard mechanism 1. The mudguard mechanism 1 includes a fixed plate 101 and a movable plate 102. The outer walls of the fixed plate 101 and the movable plate 102 are provided with an applicating mechanism 2. The applicating mechanism 2 includes an engineering plastic alloy 201 provided on the front outer wall of the fixed plate 101 and the movable plate 102, and a fiberglass 202 provided on the rear outer wall of the fixed plate 101 and the movable plate 102.

[0036] Both the fixed plate 101 and the movable plate 102 are provided with an adjustment mechanism 3. The adjustment mechanism 3 includes mounting grooves 306 opened on both sides of the upper end inside the movable plate 102. The mounting grooves 306 are provided with sliding rods 305. The rods of the sliding rods 305 are fitted with damping springs 304 and positioning pins 302. The outer walls on both sides of the fixed plate 101 are provided with positioning holes 301.

[0037] It can effectively solve the problem that existing technologies cannot meet the usage conditions in extreme environments.

[0038] Reference Figure 2 :

[0039] Mounting plates 4 are fixedly connected to both sides of the upper surface of the fixed plate 101. The mounting plates 4 make it easier to install the mudguard. The fixed plate 101 has a movable groove 5 inside, and the movable plates 102 slide inside the movable groove 5. The movable groove 5 makes it easier to slide the movable plates 102, and also makes it easier for the positioning pin 302 to be inserted into the positioning hole 301.

[0040] Reference Figure 3 and Figure 4 :

[0041] A damping spring 304 is sleeved on the side of the slide rod 305 near the middle of the movable plate 102. The positioning posts 302 slide on the side of the slide rod 305 away from the damping spring 304. The positioning posts 302 have a storage cavity 303 inside. The damping spring 304 can make it easier to reset the positioning posts 302. The storage cavity 303 can store one end of the slide rod 305 when the positioning posts 302 move. A silicone pad 307 is fixedly connected to the outer wall of the side of the positioning posts 302 away from the movable plate 102. The silicone pad 307 can effectively improve the pressing feel of the positioning posts 302. The positioning posts 302 are all engaged with positioning holes 301. The positioning posts 302 and positioning holes 301 can make it easier to fix the height of the movable plate 102.

[0042] Working principle: In use, the mudguard is installed on the rear end of the inner wheel arch of the car using the mounting plate 4. The height of the mudguard is then adjusted according to the height of the vehicle chassis. During adjustment, first press the positioning pins 302 on both sides, which compress the damping springs 304 and enter the mounting groove 306. Then, pull the movable plate 102 to slide inside the movable groove 5. When it slides to the appropriate height, the positioning pins 302 are engaged into the positioning holes 301 by the elastic force of the damping springs 304, thereby fixing the height of the movable plate 102. This step can also be adjusted before fixing it to the inner wheel arch of the car. When the mudguard is installed on military or special vehicles, the engineering plastic alloy 201 improves the corrosion resistance and impact resistance of the movable plate 102. The fiberglass 202 improves the corrosion resistance and high temperature resistance of the movable plate 102, allowing the mudguard to be used normally under different operating temperatures.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
