Further, reference herein to "one embodiment" or "an embodiment" means that a particular feature, structure, or characteristic can be included in at least one implementation of the application. The appearances of the phrase "in one embodiment" in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments.

Example 1

Referring to fig. 1 to 3 and 7, a first embodiment of the present application provides an autonomous driving tractor for civil aviation, in which a movable mud flap 201 is provided to accelerate the falling speed of clay attached to the mud flap 201.

Specifically, the tractor component C comprises a vehicle body C-1, a carriage C-2 arranged in the vehicle body C-1 and a saddle C-3 arranged in the carriage C-2; the support assembly 100 is arranged outside the vehicle body C-1 and comprises an outer frame 101, a first connecting channel 101a integrally formed outside the outer frame 101, a water delivery groove 101a-1 arranged in the first connecting channel 101a and a water outlet 101b arranged outside the outer frame 101 and communicated with the water delivery groove 101a-1, and an inner lining plate 102 is screwed in the first connecting channel 101 a; and the mud guard assembly 200 comprises a mud guard 201 movably connected with the inner lining plate 102, and a diversion end 202 is arranged on the outer wall of the mud guard 201.

Wherein the tractor assembly C is an autopilot measurement, the passenger compartment C-2 is used for passenger loading in civil aviation, and how the support assembly 100 is connected to the vehicle body C-1 is well documented in the art and will not be described herein.

In summary, in a specific use process, as shown in fig. 7, since the bottom side of the outer wall of the fender 201 is provided with a guiding end 202, the bottom of the guiding end 202 tends to be sharp when viewed in cross-section, and the guiding end 202 will unbalance the fender 201, that is, the fender 201 is in an inclined state without being affected by external force, and the gap between the bottom side of the fender 201 and the inner liner 102 is slightly smaller than the gap between the top side of the fender 201 and the inner liner 102.

During running of the vehicle, there will be a certain inertia, which will cause the mud flap 201 to rotate and to oscillate repeatedly due to striking the inner lining 102, thereby accelerating the fall of clay. The liquid adhered to the mud guard 201 is easier to enter the water delivery groove 101a-1 and is discharged from the water outlet 101b, so that the effect of reducing the raised splash is achieved, and the mud guard function is optimized.

Example 2

Referring to fig. 1 to 5 and 7, a second embodiment of the present application is based on the previous embodiment, except that the vibration of the fender 201 is accelerated by giving an external force to the fender 201 by wind energy generated during the running of the vehicle.

Specifically, the opening of the outer wall of the outer frame 101 is in threaded connection with a sleeve 300, a limiting ring 301 is rotationally arranged in the sleeve 300, an air inlet 101c is formed in the outer wall of the outer frame 101, and a first air guide channel which can be communicated with the air inlet 101c is formed in the inner wall of the sleeve 300 in a penetrating manner. Wherein most of the wind will contact the cambered surface of the outer wall of the outer frame 101 during the running of the vehicle, i.e. the wind will be poured in from the air inlet 101 c.

The inner wall of sleeve 300 has seted up arc wall 300a, and the terminal surface of spacing ring 301 is provided with can take place sliding fit's with arc wall 300a connection slider 301b, and the draw-in groove 301a has been seted up to the inner wall of spacing ring 301, and the one end of sleeve 300 can be dismantled and be provided with shield 302, and the terminal surface of shield 302 has run through and has seted up air-out passageway 302a. The arcuate groove 300a may be defined by the limit ring 301 when being matched with the connecting slider 301b, and it should be noted that, to enhance driving safety, the limit ring 301 is used to close the air inlet 101c to fix the mud guard 201, which will be described in detail in embodiment 3.

The outer wall of the limit ring 301 is provided with a second air guide channel 301c in a penetrating way; in the initial state, the connecting slider 301b is located at one side of the arc-shaped slot 300a, and at the same time, the second air guiding channel 301c, the first air guiding channel and the air inlet 101c are communicated, and when the limiting ring 301 rotates, the connecting slider 301b will displace in the stroke of the arc-shaped slot 300 a. Wherein, as described above, only when the connecting slider 301b is located at one side of the arc-shaped slot 300a, the second air guiding channel 301c, the first air guiding channel and the air inlet 101c are mutually communicated, and once the limiting ring 301 rotates, the limiting ring 301 seals the air guiding channels by its own structural feature when the connecting slider 301b moves on the arc-shaped slot 300 a.

Specifically, a transmission assembly is further disposed in the sleeve 300, and the transmission assembly includes a transmission disc 401 rotatably disposed in the sleeve 300. A transmission shaft 402 is provided in the axial direction of the transmission plate 401, a transmission passage 101d is provided in the outer wall of the inner liner 102, and one end of the transmission shaft 402 extends into the transmission passage 101d and is provided with a cam 402a. When the transmission shaft 402 is controlled to rotate, the cam 402a moves along with the rotation, and impacts the mud guard 201, so as to accelerate the shaking of the mud guard 201, and realize quick falling of clay.

In summary, when the vehicle is traveling, the transmission shaft 402 rotates to drive the cam 402a to displace in the transmission channel 101d, and when the cam 402a rotates, as shown in fig. 7, the protruding end of the cam 402a contacts the fender 201, so as to apply an external force to the fender 201, and make one side of the fender 201 repeatedly oscillate when striking the lining board 102.

Example 3

Referring to fig. 1 to 7, in a third embodiment of the present application, the rotation of the transmission shaft 402 is realized by wind energy generated during driving, and it should be additionally described that, if the driving is performed in windy weather or at a fast driving speed, the transmission shaft 402 is prohibited from being displaced and the mud guard 201 is prevented from being rotated to ensure driving safety, prolong the service life of the mud guard 201, and limit the service life of the mud guard 201.

Specifically, the other end of the transmission shaft 402 is provided with a fan blade 402b, the end face of the transmission disc 401 is movably provided with a plurality of claws 403, the outer wall of each claw 403 is provided with a second connecting channel, and the end face of each claw 403 is provided with a locking through hole 403a which can be communicated with the second connecting channel. The fan blades 402b are configured to utilize wind in the sleeve 300, so as to drive the transmission shaft 402 to rotate.

The end face array of the transmission disc 401 is in threaded connection with a plurality of fixing blocks 401a, and a third connecting channel is formed in the outer wall of the fixing block 401a in a penetrating mode. The third connecting channel is movably provided with a connecting rod 401a-1, one end of the connecting rod 401a-1 extends into the second connecting channel by penetrating through the third connecting channel, and is provided with a plug rod 401a-11, and one end of the plug rod 401a-11 extends into the sleeve 300 by penetrating through the locking through hole 403a. The number of the fixing blocks 401a corresponds to the number of the claws 403 one by one, and in this embodiment, the number of the fixing blocks 401a and the claws 403 is three.

The claw 403 is similar to a pawl, and one end of the claw is connected with the driving disk 401, and when the claw is unfolded at the connection point with the driving disk 401, the claw is clamped into the clamping groove 301a in the limiting ring 301, so that the limiting ring 301 is driven to rotate.

The other end of the connecting rod 401a-1 is connected with a limit column in a threaded manner, an elastic piece 401a-2 is sleeved on the outer wall of the connecting rod 401a-1, and the position of the elastic piece 401a-2 is located between the limit column and the fixed block 401 a. Wherein the link 401a-1 functions to limit the extension angle of the claw 403 to prevent it from rotating excessively, and the elastic member 401a-2 is a compression spring for the rebound of the claw 403, i.e., its return.

In summary, when the wind speed of the vehicle is low during low-speed driving or in the driving environment of the vehicle, the mud guard 201 needs to deflect and repeatedly swing to drop the accelerated clay, as described in embodiment 2, wind enters from the air inlet 101c and gradually enters into the sleeve 300 through the first air guide channel and the second air guide channel 301c, so that the fan blade 402b is stressed, and the cam 402a is driven to rotate through the transmission shaft 402, so that the mud guard 201 is impacted to make the accelerated clay oscillate.

When the running speed or wind speed is high, the fan blades 402b will drive the transmission shaft 402 to rotate at a high speed, the transmission disc 401 rotating at a high speed will also rotate at a high speed, the connecting rod 401a-1 will be displaced under the influence of centrifugal force, and one end of the claw 403 will be thrown out and enter the clamping groove 301a in the stroke of the inserting rod 401a-11 and the locking channel 403a to drive the limiting ring 301 to rotate.

The rotation of the limiting ring 301 will close the air inlet, and in the environment not receiving wind energy, the fan blades 402b drive the transmission shaft 402 to stop rotating, and the cam 402a will abut against the mudguard 201, so that the bottom of the diversion end 202 contacts with the inner lining plate 102, and the clamping of the mudguard 201 is completed.

It should be noted that, when the running speed is too high, the vibration caused by the vehicle will be transmitted to the mud guard 201, so that the clay on the mud guard 201 will be accelerated and fall off, but if the mud guard 201 is not fixed, the mud guard 201 will impact the inner lining plate 102 quickly to greatly accelerate the wear degree of the mud guard 201, and a certain potential threat will be brought to the running safety. After the end of the stroke, one skilled in the art can manually reset stop collar 301.
