The following description will be made taking the following device 1 provided at the left steering wheel as an example.
The follower device 1 comprises an outer plate 11, an inner plate 12 and a push-pull member 13. The outer plate 11 and the inner plate 12 are arc plates slightly larger than a quarter arc. Wherein the outer plate 11 is fixed on the frame, the upper end of the outer plate 11 is positioned at the front upper part of the axle center of the left steering wheel, and the lower end is positioned at the rear lower part of the axle center of the left steering wheel. An arc groove 111 is provided on the left side surface of the outer plate 11, a vertical-direction rotary pin 112 is provided on the upper end portion of the arc groove 111, and an extension line of the geometric axis of the rotary pin 112 perpendicularly intersects with the axis of the left steering wheel. The inner plate 12 is disposed within the arcuate slot 111, and the inner plate 12 mates with the arcuate slot 111. The upper end of the inner plate 12 is provided with a pin hole 121 matched with the pin 112, and the upper end of the inner plate 12 is pivoted to the upper end of the arc-shaped groove 111 through the pin 112 and the pin hole 121. When the automobile turns right, the upper end of the inner plate 12 rotates along the rotary pin 112, and the lower end of the inner plate 12 extends leftwards from the lower end of the arc-shaped groove 111 to block mud, sand, sewage and other dirt thrown out by the left steering wheel.
In order to avoid the collision of the upper end of the inner plate 12 with the upper end of the arc-shaped groove 111 when rotating along the rotating pin 112, an arc chamfer surface is arranged at the upper end of the inner plate 12, and the geometric rotating shaft of the arc chamfer surface is coaxial with the axle center of the pin hole 121.
In order to prevent dirt from entering the arc-shaped groove 111, a water-blocking sealing strip 113 is arranged at the notch of the arc-shaped groove 111, and the water-blocking sealing strip 113 is matched with the upper side surface and the lower side surface of the inner plate 12.
A mounting groove 122 is provided in the inner plate 12 on the left side of the arc-shaped groove 111. The push-pull member 13 has one end fixed in the installation groove 122 and the other end fixed at the bottom of the arc-shaped groove 111 corresponding to the installation groove 122, and the push-pull member 13 is used to extend or retract the lower end of the inner plate 12 from the lower end of the arc-shaped groove 111.
