Abstract
The invention discloses a protection lock mechanism. The electromagnetic lock comprises a lock pin, a power pin, a first electromagnetic induction element and a first elastic element. A power pin acts on the lock pin, and the power pin can move relative to the lock pin to engage with or disengage from the lock pin. The first electromagnetic induction element is arranged on the power pin and used for driving the power pin to apply acting force to the lock pin along the retraction direction under the action of external electromagnetic equipment. The first elastic member is connected to an end of the lock pin for applying a force to the lock pin in a protruding direction. When the first electromagnetic induction element is attracted with the external electromagnetic equipment, the first electromagnetic induction element applies acting force to the lock pin along the retraction direction so as to enable the lock pin to be in the retraction state. When the first electromagnetic induction element is separated from the external electromagnetic equipment, the first elastic element applies acting force to the lock pin along the extending direction, so that the lock pin is in the extending state. The protection lock mechanism enables the lock pin to be switched between the extending state and the retracting state in an electromagnetic mode, and is high in efficiency and reliability.

The power pin 103 acts on the lock pin 102, and the power pin 103 can move relative to the lock pin 102 to engage with or disengage from the lock pin 102. The first electromagnetic induction element 104 is disposed on the power pin 103, and the first electromagnetic induction element 104 is configured to drive the power pin 103 to apply an acting force to the lock pin 102 along a retraction direction of the lock pin 102 under the action of an external electromagnetic device. A first elastic member 105 is attached to an end of the lock pin 102, and the first elastic member 105 is used to apply a force to the lock pin 102 in a protruding direction of the lock pin 102.
Wherein, when the first electromagnetic induction element 104 is engaged with an external electromagnetic device, the power pin 103 is separated from the lock pin 102 and applies a force in a retracting direction to the lock pin 102 to put the lock pin 102 in a retracted state. When the first electromagnetic induction element 104 is separated from the external electromagnetic device, the first elastic element 105 applies a force to the lock pin 102 in the extending direction, and the power pin 103 engages with the lock pin 102 to place the lock pin 102 in the extending state. In the present embodiment, the first elastic element 105 is a spring.
In the present embodiment, the protection lock mechanism 10 enables the power pin 103 to be engaged with or disengaged from the lock pin 102 relatively quickly and reliably through the cooperation of the first electromagnetic induction element 104 and the external electromagnetic device, so that the lock pin 102 can be switched between the extended state and the retracted state relatively quickly and reliably, and the efficiency and reliability of switching between the extended state and the retracted state of the protection lock mechanism can be improved.
As will be appreciated with reference to fig. 1-5, the locking pin 102 has an actuating portion 1021, a connecting portion 1022. The connecting portion 1022 is connected to one end of the actuating portion 1021 along the length direction of the actuating portion 1021, and the connecting portion 1022 has a first receiving cavity 1023, and the first receiving cavity 1023 is used for receiving the power pin 103. The first elastic element 105 is connected to an end of the connection part 1022 far from the executing part 1021, and the first elastic element 105 applies a force to the connection part 1022 in the extending direction. In the present embodiment, when the power pin 103 is engaged with the lock pin 102, one end of the power pin 103 close to the lock pin 102 is engaged with the first receiving cavity 1023, which belongs to embedded connection and occupies less space.

It should be noted that in other alternative embodiments, the first included angle may be set to any angle between more than 0 ° and less than 90 °.
As will be understood by referring to fig. 1 to 4 and fig. 6, the power pin 103 has a head end and a tail end along the height direction thereof, the head end of the power pin 103 is embedded in the first receiving cavity 1023, and the first electromagnetic induction element 104 is disposed at the tail end of the power pin 103. The first accommodation cavity 1023 has a first inclined part 1024 on the inner wall surface, and the head end of the power pin 103 has a second inclined part 1032 fitting the first inclined part 1024. When the power pin 103 is engaged with the lock pin 102, the first inclined part 1024 is attached to the second inclined part 1032; when the power pin 103 is separated from the lock pin 102, the second inclined portion 1032 moves downward relative to the first inclined portion 1024 and applies a force in the retracting direction to the lock pin 102 to place the lock pin 102 in the retracted state.
In the present embodiment, by skillfully utilizing the cooperation of the first inclined part 1024 and the second inclined part 1032, when the power pin 103 moves in a direction away from the lock pin 102, the first inclined part 1024 slides relative to the second inclined part 1032, and the frictional force applied to the second inclined part 1032 by the first inclined part 1024 can be decomposed into a component force in the retracting direction, under which the lock pin 102 retracts.

The force applied to the power pin 103 by the second elastic member 106 is greater than the weight force of the power pin 103. In the present embodiment, when the power pin 103 is engaged with the lock pin 102, the urging force applied to the power pin 103 by the second elastic member 106 can prevent the power pin 103 from falling down by gravity, and thus the reliability of the engagement of the power pin 103 with the lock pin 102 can be further improved. When the power pin 103 needs to move towards the direction close to the lock pin 102, the acting force applied to the power pin 103 by the second elastic element 106 can overcome the gravity of the power pin 103, so that the power pin 103 can move towards the direction close to the lock pin 102 more reliably.

the locking pin is positioned in the second accommodating cavity, and the execution part is arranged in the through hole in a penetrating way so as to switch between the extending state and the retracting state; the first elastic element is positioned in the second accommodating cavity and abuts against between one end, far away from the execution part, of the connecting part and the inner wall surface of the second accommodating cavity;
the second lower shell is connected to the bottom of the first lower shell and provided with a third accommodating cavity, the third accommodating cavity is communicated with the second accommodating cavity, and the power pin is positioned in the third accommodating cavity;
a blocking part is arranged on the outer wall surface of the power pin and corresponds to one end of the second elastic element, and the second elastic element is clamped between the blocking part and the second lower shell;
and/or the second elastic element is a spring.
10. The dongle mechanism of claim 3, further comprising:
the locking pin is positioned in the second accommodating cavity, and the execution part is arranged in the through hole in a penetrating way so as to switch between the extending state and the retracting state;
the second lower shell is connected to the bottom of the first lower shell and provided with a third accommodating cavity, the third accommodating cavity is communicated with the second accommodating cavity, and the power pin is positioned in the third accommodating cavity;
and/or a second included angle is formed between the central axis of the second lower shell and the central axis of the first lower shell, and the second included angle is equal to the first included angle.
11. The protective lock mechanism of claim 10 wherein the first lower housing is integrally formed with the second lower housing.
