DETAILED DESCRIPTION

[0024] See also Figure 1-5 The utility model provides a technical solution: a new automobile fender that can avoid silt accumulation, comprising a plate body 1, a connecting plate 2 is fixedly mounted on the plate body 1, and a plurality of mounting holes 3 are opened on the connecting plate 2, so that the fender is mounted on the front side of the wheel by aligning the mounting holes 3 on the connecting plate 2 with the screw holes of the outer frame of the automobile wheel, and screwing the bolts through the mounting holes 3 into the screw holes;

[0025] Specifically, the front side of the plate body 1 is rotatably connected to the rotating shaft 4, and the rotating shaft 4 is arranged on the side of the plate body 1 facing away from the wheel. Since the fender is installed on the front side of the wheel, the rotating shaft 4 is on the windward side of the plate body 1, and the fan blades 5 are fixedly sleeved on the outer surface of the rotating shaft 4. In this way, when the vehicle is driving, since the fan blades 5 are on the windward side of the plate body 1, the airflow will form a thrust on the blades of the fan blades 5, so that the fan blades 5 can drive the rotating shaft 4 to rotate.

[0026] Specifically, a mounting block 6 is fixedly mounted on the back of the plate body 1, a connecting groove 8 is opened on the side of the mounting block 6, a ball screw 9 is rotatably connected between the inner walls on the upper and lower sides of the connecting groove 8, a movable slider 10 is sleeved on the outer surface of the ball screw 9, the movable slider 10 slides in the connecting groove 8, a ball nut is provided on the movable slider 10, the movable slider 10 is sleeved on the outer surface of the ball screw 9 through the ball nut thread, the connecting groove 8 is extended from one side of the movable slider 10, a scraper 7 is provided on the side of the movable slider 10 outside the connecting groove 8, the scraper 7 is inclined, and the lower side is in contact with the back of the plate body 1;

[0027] When the ball screw 9 rotates, the movable slider 10 is driven by the ball nut to move back and forth on the ball screw 9, so the scraper 7 can be displaced synchronously with the movable slider 10. In this way, when the scraper 7 moves downward, the scraper 7 can automatically scrape off the silt on the back of the plate body 1, thereby avoiding as much as possible the accumulation of excessive silt on the mudguard when the mudguard is used for a long time. There is no need to remove the mudguard to clean it, which solves the problem of mud clogging between the mudguard and the tire.

[0028] Specifically, a control chamber 11 is opened in the mounting block 6, and the upper end of the ball screw 9 rotates and passes through the control chamber 11. The upper end of the ball screw 9 is fixedly connected with a bevel gear 12, and the end of the rotating shaft 4 away from the fan blades 5 rotates and passes through the control chamber 11. The end of the rotating shaft 4 located in the control chamber 11 is also fixedly connected with a bevel gear 12. The two bevel gears 12 are meshed and connected. Therefore, when the fan blades 5 drive the rotating shaft 4 to rotate, the two bevel gears 12 are synchronously meshed and drive the ball screw 9 to rotate. The above structure makes it possible for the cleaning structure to not require an additional electric component to drive the scraper 7 to move, so that the mechanism has good environmental value and environmental significance.

[0029] Specifically, a connecting cavity 13 is provided in the movable slider 10, and the connecting cavity 13 is provided on a side close to the scraper 7. A control shaft 14 is fixedly connected to a surface of the scraper 7 close to the movable slider 10, and the other end of the control shaft 14 rotates and penetrates into the connecting cavity 13. A gear 15 is fixedly sleeved on one end of the control shaft 14 located in the connecting cavity 13, and a rack 16 is meshed and connected at the bottom of the gear 15, and the rack 16 slides on the bottom wall of the connecting cavity 13.

[0030] When the rack 16 moves backward, the rack 16 can engage the transmission gear 15 to rotate counterclockwise, so that the control shaft 14 drives the scraper 7 to rotate counterclockwise, so that the scraper 7 rotates to a vertical state, so that the scraper 7 no longer contacts the plate body 1.

[0031] Specifically, a push rod 17 is fixedly connected to the front side surface of the rack 16, and the other end of the push rod 17 slides through the front side surface of the movable slider 10. A tension spring 18 is fixedly connected between the rack 16 and the inner wall of the connecting cavity 13. The tension spring 18 is movably sleeved on the outer surface of the push rod 17. One end of the push rod 17 located outside the movable slider 10 is rotatably connected to a contact rod 19. A torsion spring is provided between the contact rod 19 and the push rod 17, so the contact rod 19 is vertical with the push rod 17 under the action of the torsion spring. The strength of the torsion spring is less than the strength of the tension spring 18. A control block 21 is fixedly connected to the inner wall of the front side of the connecting groove 8. The shape of the control block 21 is an isosceles trapezoid. The other end of the contact rod 19 contacts with the rear side surface of the control block 21 and slides. A baffle 20 is fixedly connected to the lower surface of the contact rod 19, and the other side of the baffle 20 contacts with the lower surface of the push rod 17.

[0032] Therefore, when the movable slider 10 slides from top to bottom, the contact rod 19 contacts the inclined surface on the upper side of the control block 21 and slides. At this time, the inclined surface of the control block 21 will squeeze the contact rod 19. Since the strength of the torsion spring is less than the strength of the tension spring 18, the contact rod 19 cannot drive the push rod 17 to move. At this time, the contact rod 19 rotates clockwise on the push rod 17, and the torsion spring is deformed. When the movable slider 10 slides to the bottom, the contact rod 19 is no longer in contact with the control block 21. At this time, the contact rod 19 rotates to the initial position under the action of the torsion spring. When the movable slider 10 moves from bottom to top, the contact rod 19 moves along the inclined surface of the control block 21. The contact rod 19 slides upward because a baffle 20 is provided at the bottom thereof. The baffle 20 will restrict the contact rod 19 and prevent the contact rod 19 from rotating counterclockwise. As a result, the contact rod 19 generates a thrust on the push rod 17, thereby causing the push rod 17 to move rearward. At this time, the rack 16 can drive the gear 15 to rotate counterclockwise. In this way, when the movable slider 10 moves upward, the rotation of the scraper 7 can be automatically controlled, so that the scraper 7 will not scrape the surface of the plate body 1, and the sludge on the surface of the plate body 1 is avoided as much as possible, resulting in the accumulation of the sludge between the scraper 7 and the plate body 1 when the scraper 7 scrapes upward, thereby further ensuring the cleaning effect of the scraper 7.

[0033] Working principle: When the vehicle is driving, since the fan blades 5 are on the windward side of the plate body 1, the airflow will form a thrust on the fan blades 5, so that the fan blades 5 can drive the rotating shaft 4 to rotate, and the two bevel gears 12 are synchronously engaged to drive the ball screw 9 to rotate. The movable slider 10 is driven by the ball nut to move up and down on the ball screw 9, so the scraper 7 can be displaced synchronously with the movable slider 10. In this way, when the scraper 7 moves downward, the scraper 7 can automatically scrape off the silt on the back of the plate body 1.
