Please refer to FIG. 4A, since the gravity FG of the cover body 310 can be seen to be twice C and point to the negative direction of the Y axis, the gravity moment generated by the cover body 310 relative to the brother-rotation axis 32 () is counterclockwise. Second, the effective radius RG of this gravity moment is the distance from the center of the first frame rotation axis to a parallel line passing through the center of gravity c and parallel to the γ axis. On the contrary, relative to the clockwise moment generated by the first pinning shaft 320: ° its-'is provided by the rotation resistance ff of the arc plane 252 of the cantilever 250 and the rotating wheel 230 _ at the junction ρ. In Θ, because the biasing element 24 is in a compressed state, it provides a biasing force along and pointing to the axis of the second frame rotation axis 232; this keeps the damping wheel 230 in contact with the curved plane 252, and then The consumption point p between 230 and the curved plane 252 does not produce the rotational resistance FF of the sliding plane 252 relative to the rotational resistance torque generated by the first pivot axis 320 in a clockwise direction, and the effective radius RF of the moment is the first pivot The distance from the axis of the shaft 320 to a tangent passing through the joint P and tangent to the damping wheel 230. The above-mentioned amount of bias causes the damping wheel 230 to be in contact with the fox-shaped plane 252 and further causes the light-contact point ρ of the damping wheel 230 and the arc-shaped plane 252 to generate a positive force FN. The positive force acting on the arc-shaped plane 252 is opposite; the positive force moment generated by the holding axis 320 is clockwise, and the effective radius RN of this positive force moment is the first pivot axis 32. A M282210 16286t \ vf.doc / m The distance between the line connecting the consumption point P and the 232 axis of the second pivot axis. Please refer to FIGS. 4A and 4B at the same time. When the cover body 310 is rotated from FIG. 4A to FIG. 4B, the cantilever 25 ° drives the damping wheel 23 ° to rotate along the second pivot axis 232. It is worth noting that although the gravity moment The effective radius RG increases and increases, but because the radius R1 of the arc-shaped plane 252 of the cantilever 25 relative to the axis of the first pivot axis 320 will increase as the cover 31 gradually covers the body 300 (see FIG. 2), Therefore, the effective radius RF of the rotational resistance torque of the damping wheel 23 is also relatively increased. At the same time, the biasing element 24o will be further compressed to generate a greater biasing force than that shown in FIG. 4A. Therefore, the effective radius RF of the rotational resistance torque and the forward force FN are relatively increased, because: the square rotation resistance torque and the forward force torque (both are clockwise) can be offset by some of the gravity torque (counterclockwise) Direction), so that the cover body 31 slowly covers the body 300 (see FIG. 2). From the above, it can be known that the rotating mechanism of this embodiment can be used to offset a part of the counter moment of the gravity moment in three ways. They are respectively adjusting the radius R1 of the cantilever plane 252 to the first axis of rotation 320 of the center of gravity of the vehicle, adjusting the rotation resistance damping value of the second body, and adjusting the biasing element of the green 2 as described when the cover is gradually covering the body During the process, the contact point between the Γ arm and the damping wheel is relatively increased relative to the first pivot point ^, so that the contact between the damping wheel and the cantilever relatively increases the forward force moment and the rotational resistance moment of the heart. Increased gravitational force = Sustained by the cover relative to the axis of the first-pivot axis. Therefore, reduce the impact and noise of the cover when covering the body.
