Damping mechanism and vehicle

A vehicle, comprising a vehicle body,

• wherein a front end the vehicle body being mounted with a damping mechanism;
• or
• a rear end of the vehicle body being mounted with a damping mechanism;
• or
• both the front end and the rear end of the vehicle body being mounted with a damping mechanisms;
• the damping mechanism comprising:
• a spindle;
• an elastic cushion assembly configured to couple the spindle and the vehicle body;
• a coupling arm having a first end configured to be fixedly coupled to an axle of the wheel and a second end pivotally coupled to the spindle;
• and
• a locking assembly provided between the coupling arm and the spindle and configured to switch the coupling arm and the spindle between at least two locking states and an unlocking state,
• wherein in the unlocking state, the coupling arm is rotatable relative to the spindle, and in the locking states, the coupling arm is locked relative to the spindle;
• in each of the locking states, the coupling arm is in different locking positions relative to the spindle;
• and when the coupling arm is in different locking positions, the coupling arm is at different angles relative to a horizontal plane,
• wherein the locking assembly comprises:
• an anti-rotation assembly provided between the coupling arm and the spindle and configured to hinder relative rotation of the coupling arm and the spindle when in the locking states;
• and an axial limiting member movably provided to the spindle, the coupling arm having a through hole for the spindle passing through, the axial limiting member being located at a side of the coupling arm away from the anti-rotation assembly and configured to abut against the coupling arm along an axial direction in the locking states;
• wherein the anti-rotation assembly comprises:
• a first anti-rotation member provided to the coupling arm, and a second anti-rotation member provided to the spindle and fixed to the spindle along the circumferential direction:
• wherein;
• the first anti-rotation member is fitted over the second anti-rotation member, and the second anti-rotation member has a latch position and a non-latch position on a stile surface of the second anti-rotation member;
• in the locking state, the first anti-rotation member abuts against the latch position of the second anti-rotation member to grip the coupling arm, the first anti-rotation member find the second anti-rotation member in the unlocking state, the first anti-rotation member moves to the non latch position of the second anti-rotation;
• member to enable relative rotation of at least two of the coupling arm, the first anti-rotation member and the second anti-rotation member;
• and
• wherein the first anti-rotation member comprises r roller cage and a plurality of rollers provided on the roller cage, the roller cage is provided in an accommodating cavity of the coupling arm, the plurality of rollers are distributed to a side surface of the roller cage along the circumferential direction, and the rollers is removable in a radial direction of the roller cage;
• the second anti-rotation member is a ratchet wheel fixed to the spindle along the circumferential direction, and the ratchet wheel is fitted inside the roller cage;
• in the locking state, the roller abuts between a wall of the accommodating cavity and the latch position of the ratchet wheel to grip the coupling arm, the roller and the ratchet wheel tightly;
• in the unlocking state, the roller moves to the non-latch position of the ratchet wheel along the radial direction, and the coupling arm is rotatable relative to the roller cage and the ratchet wheel.

• at least two locking states and an unlocking state,
• wherein in the unlocking state, the coupling arm is rotatable relative to the spindle, and in the locking states, the coupling arm is locked relative to the spindle;
• in each of the locking states, the coupling arm is in different locking positions relative to the spindle;
• and when the coupling arm is to different locking positions, the coupling arm is at different angles relative to a horizontal plane,
• wherein the locking assembly comprises:
• an anti-rotation assembly provided between the coupling arm and the spindle and configured to hinder relative rotation of the coupling arm and the spindle when in the locking states;
• and an axial limning member movably provided to the spindle, the coupling arm having a through hole for the spindle passing through, the axial limiting member being located at a side of the coupling arm away from the anti-rotation assembly and configured to abut against the coupling arm along an axial direction in the locking states;
• wherein the elastic cushion assembly comprises:
• a cushioning cavity comprising a cavity wall and a receiving cavity enclosed by the cavity wall, the cavity wall being fitted over the spindle and fixedly coupled to the vehicle body;
• and a cushioning member accommodated in the receiving cavity and abutting against the cavity wall and the spindle;
• and
• wherein the cushioning cavity further comprises two lateral cavity covers, and the two lateral cavity covers are detachably coupled to two ends of the cushioning cavity, respectively;
• the two lateral cavity covers are sealingly coupled to the cushioning cavity.
