[0059] In the embodiment of the present application, the fairlead assembly 100 is applied to a vehicle, the vehicle comprising a vehicle frame 200 and a front axle 300 and a rear axle 400 arranged at the bottom of the vehicle frame 200, and the fairlead assembly 100 comprising:

[0060] a front cover assembly 110 arranged between the front axle 300 and the vehicle frame 200 and detachably connected with the vehicle frame 200;

[0061] a rear cover assembly 130 arranged between the rear axle 400 and the vehicle frame 200 and detachably connected with the vehicle frame 200; and

[0062] a middle cover assembly 120 arranged on the side of the vehicle frame 200 facing the ground and detachably connected with the vehicle frame 200, and the front cover assembly 110 and the rear cover assembly 130 being arranged at opposite ends of the middle cover assembly 120 along the length direction of the vehicle.

[0063] The fairing assembly 100 in the technical scheme of one embodiment of the present application is applied to the bottom of the vehicle, and the fairing assembly 100 comprises a front cover assembly 110, a middle cover assembly 120 and a rear cover assembly 130, and the front cover assembly 110, the middle cover assembly 120 and the rear cover assembly 130 are arranged along the length direction of the vehicle. The front cover assembly 110 is arranged between the front axle 300 and the vehicle frame 200, the rear cover assembly 130 is arranged between the rear axle 400 and the vehicle frame 200, and the middle cover assembly 120 is arranged between the front cover assembly 110 and the rear cover assembly 130, so as to cover the bottom of the vehicle from the front axle 300 to the rear axle 400 along the length direction of the vehicle, thereby achieving a certain protection effect, reducing the possibility of damage to the vehicle chassis, reducing the possibility of air vortex at the bottom of the vehicle during driving of the vehicle, thereby reducing air resistance during driving of the vehicle and reducing driving noise of the vehicle. The front cover assembly 110, the middle cover assembly 120 and the rear cover assembly 130 are detachably connected with the vehicle frame 200, which can be achieved by bolt locking or clamping, etc. The fairing assembly 100 is conveniently disassembled through detachable connection, so as to facilitate maintenance and replacement of parts at the bottom of the vehicle.

[0064] In an embodiment, at least one of the front cover assembly 110, the rear cover assembly 130 and the middle cover assembly 120 comprises a plurality of cover bodies arranged in a split manner, and the plurality of cover bodies are spliced.

[0065] In the embodiment, at least one of the front cover assembly 110, the rear cover assembly 130 and the middle cover assembly 120 can be arranged in a plurality of cover bodies arranged in a split manner and spliced, which on the one hand makes the volume of each cover body smaller and the weight lighter, and the cover body can be directly taken out and assembled by manpower during disassembly, thereby improving the disassembly efficiency; on the other hand, when the parts at the bottom of the vehicle are maintained and replaced, only one or several cover bodies at the relevant position need to be disassembled, instead of disassembling the entire cover assembly, thereby reducing the disassembly difficulty and improving the disassembly efficiency, for example, when a certain part is located at the junction of the front cover assembly 110 and the middle cover assembly 120, only the cover bodies of the front cover assembly 110 and the middle cover assembly 120 at the junction need to be disassembled, instead of disassembling the entire front cover assembly 110 and the middle cover assembly 120; on the other hand, the front cover assembly 110 is arranged in a plurality of cover bodies arranged in a split manner and spliced, which facilitates avoiding the front axle 300 during assembly, thereby preventing the front cover assembly 110 from being difficult to be assembled between the front axle 300 and the vehicle frame 200, and similarly, the rear cover assembly 130 is arranged in a plurality of cover bodies arranged in a split manner and spliced, which facilitates avoiding the rear axle 400 during assembly, thereby preventing the rear cover assembly 130 from being difficult to be assembled between the rear axle 400 and the vehicle frame 200.

[0066] In an embodiment, the plurality of cover bodies are arranged in sequence along the length direction of the vehicle; and / or,

[0067] The adjacent two cover bodies abut each other and do not overlap in the height direction of the vehicle.

[0068] In combination with FIGS. 1-2, in the present embodiment, the plurality of cover bodies are arranged along the length direction of the vehicle. Compared with being arranged along the width direction, the volume of each cover body can be smaller, and the cover body is more convenient to disassemble and assemble. Compared with being staggered, being arranged in the same direction is more regular, and is simpler to assemble.

[0069] Referring to FIG. 3, in the present embodiment, the adjacent cover bodies abut each other, so that there is no gap or a very small gap between the adjacent cover bodies and the cover bodies. This reduces the possibility of airflow entering the inside of the fairing assembly 100 from the gap between the cover bodies during the driving of the vehicle, thereby avoiding problems such as airflow passing through the gap causing abnormal noise, airflow causing the cover bodies to be loose or even to fall off from the vehicle frame 200, and the like. Moreover, the two adjacent cover bodies do not overlap in the height direction of the vehicle, thereby avoiding the situation that one cover body presses another cover body, and thereby ensuring the convenience of disassembling and assembling each cover body.

[0070] In an embodiment, the front cover assembly 110 is provided with at least one first flow guide surface 1101, which is arranged on the side of the front cover assembly 110 facing the ground and facing the forward direction of the vehicle; and / or,

[0071] The middle cover assembly 120 is provided with at least one second flow guide surface 1201, which is arranged on the side of the middle cover assembly 120 facing the ground and facing the forward direction of the vehicle; and / or,

[0072] The rear cover assembly 130 is provided with at least one third flow guide surface 1301, which is arranged on the side of the rear cover assembly 130 facing the ground and facing the forward direction of the vehicle.

[0073] Referring to FIG. 4, in the present embodiment, the first flow guide surface 1101 is arranged on the side of the front cover assembly 110 facing the forward direction of the vehicle. The first flow guide surface 1101 is inclined to the ground from the direction of the vehicle head to the vehicle tail. When the vehicle is driving, the airflow at the bottom of the vehicle flows along the first flow guide surface 1101, which not only reduces the wind resistance, but also causes the airflow to provide a certain lift to the vehicle, thereby reducing the driving resistance when the vehicle is driving forward.

[0074] Referring to FIG. 4, in the present embodiment, the second flow guide surface 1201 is arranged on the side of the middle cover assembly 120 facing the forward direction of the vehicle. The second flow guide surface 1201 is inclined to the ground from the direction of the vehicle head to the vehicle tail. When the vehicle is driving, the airflow at the bottom of the vehicle flows along the second flow guide surface 1201, which not only reduces the wind resistance, but also causes the airflow to provide a certain lift to the vehicle, thereby reducing the driving resistance when the vehicle is driving forward.

[0075] Referring to FIG. 4, in the embodiment, the rear cover assembly 130 is provided with a third flow guide surface 1301 on the side thereof facing the advancing direction of the vehicle, and the third flow guide surface 1301 is inclined to approach the ground from the front to the rear of the vehicle.
