Taking the example of only the first elastic member 100, the following specific movement process is performed when the stopper 10 receives an external impact force:
When the blocking member 10 is not subjected to external impact force in the open state, the screw abuts against the fixing seat 90 under the action of the first elastic member 100, and the buffer gap between the screw and the supporting seat 80 is at a maximum.
When the stopper 10 receives an external impact force in the open state, for example, when the stopper 10 receives an external impact force that drives the stopper 10 to move in the closing direction, referring to fig. 11 to 12, that is, a direction that drives the nut to move in the left direction along the screw, the direction is set as a first direction; when the blocking member 10 receives the external impact force in the first direction, the external impact force in the first direction is transmitted to the nut through the blocking member 10 and the connecting arm 303, the nut drives the screw rod to move along the linear track 40 towards the direction close to the rotating member 70, and presses the first elastic member 100, in this process, the buffer gap between the screw rod and the supporting seat 80 is reduced, the buffer gap between the screw rod and the fixing seat 90 is increased until the screw rod impacts the supporting seat 80, at this time, the buffer gap between the screw rod and the supporting seat 80 is 0, and the buffer gap between the screw rod and the fixing seat 90 is maximum.
When the external impact force on the blocking member 10 in the first direction disappears, the first elastic member 100 resets, under the action of the first elastic member 100, the nut drives the screw rod to move along the linear rail 40 towards the direction close to the output end of the motor, in this process, the buffer gap between the screw rod and the supporting seat 80 increases, the buffer gap between the screw rod and the fixing seat 90 decreases until the screw rod impacts the fixing seat 90, at this time, the buffer gap between the screw rod and the supporting seat 80 is the maximum value, and the buffer gap between the screw rod and the fixing seat 90 is 0.
It should be noted that, the avoiding groove 110 may be disposed at the output end of the rotating member 70 and the motor, so as to prevent the screw from impacting the output end of the rotating member 70 and the motor when the blocking member 10 receives an external impact force; naturally, the first elastic member 100 may be disposed in the first connecting hole 305, so that the damper 10 may be buffered when an external impact force in a second direction, which is opposite to the first direction, is received.
