Description

Technical Field

[0001] The utility model relates to the technical field of vehicle engineering, and particularly relates to an automobile fender assembly. Background Technique

[0002] At present, in the existing automobile design, the fender is usually a single component, and its function is mainly to prevent the sediment and stones carried by the tires during driving from splashing onto the surface of the vehicle and causing damage to the vehicle body.

[0003] For example, Chinese Patent discloses "Fender Assembly and Vehicle" (Patent No.: CN107499388B), which includes a fender body (10) and a bracket (20) fixed to one side of the fender body (10). The bracket (20) includes at least two telescopic sections, and the fender body (10) includes at least two sections respectively fixed to the corresponding brackets (20) so that the fender assembly has a contracted state and an unfolded state. The above patent has the advantages that when the fender assembly is in the unfolded state, the fender body can block dirt and other sundries. When the fender assembly is in the contracted state, since the lever arm of its cantilever beam structure becomes shorter, the moment generated at the root of the bracket is reduced, and stress concentration is avoided.

[0004] However, the above fender is difficult to meet the requirements for the fender under different wind resistances. Therefore, a fender that can change the length of the mud-blocking part of the telescopic baffle according to the degree of mud and water splashing is needed. Content of the Utility Model

[0021] An embodiment of the present utility model provides an automobile fender assembly, as Figures 1-3 shown, including a main body 11, an air inlet groove 12, an arc chute 13, a first chute 14, a second chute 15, a telescopic baffle 16, a first connecting block 17, a spring 18, a sliding piston 20, a connecting rod 21, and a second connecting block 22.

[0022] As shown Figures 1-3 in the figure, it includes a main body 11 and several telescopic baffles 16. A second sliding groove 15 is formed on one side of the main body 11, and several telescopic baffles 16 are slidably connected to the second sliding groove 15. Several drainage trough bodies are formed on the main body 11. The drainage trough bodies include an air inlet trough 12, an arc trough 13 and a first sliding groove 14. The air inlet trough 12 penetrates through the side of the main body 11 away from the telescopic baffle 16. The air inlet trough 12, the arc trough 13 and the first sliding groove 14 are sequentially connected along the extending direction of the main body 11. The diameter of the arc trough 13 is larger than that of the first sliding groove 14. An arc chamfer is provided at the connection between the arc trough 13 and the first sliding groove 14. Several drainage trough bodies are arranged on the main body 11 at equal intervals, and several drainage trough bodies correspond to several telescopic baffles 16 one by one.

[0023] Several first connection blocks 17 are arranged in the second sliding groove 15. A spring 18 is fixedly connected to the first connection block 17. One end of the spring 18 away from the first connection block 17 is fixedly connected to the telescopic baffle 16. A sliding piston 20 and a connecting rod 21 are slidably arranged in the first sliding groove 14. One end of the connecting rod 21 is fixedly connected to the sliding piston 20, and the other end of the connecting rod 21 is fixedly connected to a second connection block 22. The second connection block 22 is fixedly connected to the end of the telescopic baffle 16 away from the spring 18. Sealing rings are arranged on the contact surfaces of the sliding piston 20 and the first sliding groove 14.

[0024] When this solution is used for car mudguards, first, when the car is moving forward, the muddy water splashes onto the lower curved surface of the main body 11 along with the tires. At this time, the airflow generated by the forward movement of the car enters the air inlet trough 12 through the opening on the side of the main body 11 away from the telescopic baffle 16, so that the muddy water in the air inlet trough 12 and the arc trough 13 enters the first sliding groove 14 along the air inlet trough 12 and the arc trough 13. Then, the resultant force of the gravity of the muddy water in the first sliding groove 14 and the thrust of the airflow on the muddy water in the first sliding groove 14 pushes the sliding piston 20 to move downward. The sliding piston 20 drives the second connection block 22 to move downward through the connecting rod 21, and the second connection block 22 pulls the telescopic baffle 16 to move downward, thereby increasing the length of the mudguard part. Finally, when the car stops, the spring 18 generates a pulling force on the telescopic baffle 16, so that the sliding piston 20 and the telescopic baffle 16 are reset.

[0025] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
