Supporting leg assembly, supporting leg telescopic mechanism and carrier

A carrier, comprising:

• a base;
• a supporting leg, pivotally connected to the base and configured to pivot relative to the base;
• and
• a buffer mechanism, disposed between the base and the supporting leg and configured to contact at least one of the base and the supporting leg, wherein,
• the buffer mechanism is configured to provide resistance to a pivoting movement of the supporting leg relative to the base,
• wherein the supporting leg is configured to pivot between a folded position and an unfolded position, and the buffer mechanism comprises a buffer portion which provides resistance to a part route of pivoting of the supporting leg from the folded position to the unfolded position, and either:
• the buffer portion is formed on the supporting leg, and in a process of the supporting leg moving from the folded position to the unfolded position, the buffer portion abuts against the base, so that the buffer portion is elastically deformed to prevent the pivoting of the supporting leg;
• or
• the buffer portion is formed on the base, and in the process of the supporting leg moving from the folded position to the unfolded position, the buffer portion abuts against the supporting leg, so that the buffer portion is elastically deformed to prevent the pivoting of the supporting leg.

A carrier, comprising:

• a base, having a fixing bracket;
• a movable bracket, slidably connected to the fixing bracket, the movable bracket is capable of sliding between an extended position and a retracted position;
• a supporting leg, connected to the movable bracket;
• a buffer mechanism, disposed between the base and the movable bracket and capable of contacting at least one of the base and the movable bracket;
• and
• a restoring element, connected to the movable bracket and capable of biasing the movable bracket to a sliding direction away from the base.

A carrier comprising:

• a base that has a fixing bracket;
• a movable bracket slidably connected to the fixing bracket thereof;
• a supporting leg connected to the movable bracket;
• a first buffer mechanism disposed between the movable bracket and the supporting leg, the first buffer mechanism configured to contact at least one of the movable bracket and the supporting leg;
• a second buffer mechanism disposed between the base and the movable bracket, the second buffer mechanism configured to contact at least one of the base and the movable bracket;
• and
• a restoring element that is connected to the movable bracket and configured to bias the movable bracket in a sliding direction away from the base;
• wherein the supporting leg is configured to pivot between a folded position and an unfolded position, the first buffer mechanism includes a buffer portion, and the buffer portion provides resistance to a portion of a pivoting path of the supporting leg from the folded position to the unfolded position;
• and
• the movable bracket is configured to slide between an extended position and a retracted position, and the second buffer mechanism is configured to provide resistance to a portion of a moving path of the movable bracket from the retracted position to the extended position.
