The elastic mechanism 40 is connected with the executing piece 20 and the triggering piece 30, the triggering piece 30 is used as an action input piece of the hard disk locking assembly 100, the triggering piece 30 moves relative to the base 10 after being stressed and causes the elastic mechanism 40 to change the shape, and then the elastic mechanism 40 drives the executing piece 20 to move relative to the base 10, so that the aim of switching between the two states of locking the connecting hard disk 300 and unlocking the disconnecting hard disk 300 of the executing piece 20 is achieved, or when the elastic mechanism 40 reaches a specific shape, the position of the executing piece 20 is restrained through the cooperative matching of the elastic mechanism 40 and the base 10 in the current shape, so that the locking connecting state of the hard disk 300 can be maintained for a long time by the executing piece 20.

The utility model is defined as follows: the personnel press the trigger piece 30 to trigger the form change of the elastic mechanism 40 and realize the switching of the position state of the executing piece 20, the trigger piece 30 is provided with a plurality of positions relative to the base body 10, the positions respectively correspond to different states of the executing piece 20, the positions are distributed along the movement track of the stressed trigger piece 30, namely, the trigger piece 30 passes through the positions successively along with the force applied by the personnel to the trigger piece 30, and the positions comprise a releasing position and a fixed position.

When the trigger 30 is in the release position, the force applied by the person to the trigger 30 is weak, or the trigger 30 is not pressed by the person at this time, the elastic mechanism 40 can be compressed, that is, as the person subsequently presses the trigger 30 to enable the trigger 30 to move relative to the base 10, the elastic mechanism 40 can change its shape and gradually accumulate elastic potential energy. When the trigger 30 is in the releasing position, the actuator 20 withdraws from the inside of the base 10, and the hard disk locking assembly 100 is in a state of being unlocked and separated from the hard disk 300.

When the trigger 30 is at the fixed position, the potential energy of the elastic mechanism 40 is increased compared with that of the trigger 30 at the releasing position, and after that, even if the pressing force to the trigger 30 is withdrawn, the elastic mechanism 40 and the base 10 are cooperatively connected, so that the trigger 30 can still stay at the fixed position, the elastic mechanism 40 is in a self-locking fixed state at present, the actuator 20 can be kept in a state of extending out of the base 10 for a long time, and the hard disk locking assembly 100 is in a state of locking the hard disk 300 at the moment.

When the cam portion 441 abuts the actuator 20, the actuator 20 is pushed away from the center of oscillation 442, and at this time, the distance D1 from the end of the actuator 20 that contacts the rocker 44 to the center of oscillation 442 is set, and when the rocker 44 abuts the actuator 20 through a portion other than the cam portion 441, the distance D2 from the end of the actuator 20 that contacts the rocker 44 to the center of oscillation 442 is set to D2, and D1 > D2. As the rocker 44 is reciprocated by the link 43, the distance from the end of the actuator 20 contacting the rocker 44 to the center 442 of the rocking varies between D1 and D2.

Thus, the trigger 30, the link 43, the rocker 44 and the base 10 together form a rocker slider mechanism, the trigger 30 and the rocker 44 respectively serve as a slider member and a rocker member of the rocker slider mechanism, and the link 43 and the base 10 respectively serve as a link 43 member and a frame member of the rocker slider mechanism. The rocker 44 oscillates reciprocally with respect to the base 10 as the trigger 30 reciprocates relative to the base 10 between the released position and the bottoming position. Alternatively, the button chute 17 extends in a linear direction, and the trigger 30 can reciprocate along a linear trajectory with respect to the housing 10.

Summarizing the power transmission path of trigger 30 to implement 20: the personnel apply pressing force to the trigger piece 30, the trigger piece 30 slides relative to the base body 10, so that the shape of the rocker sliding block mechanism is changed, the trigger piece 30 drives the rocking block 44 to swing through the connecting rod 43, the rocking block 44 pushes the executing piece 20 through the cam portion 441, and therefore the executing piece 20 is pushed out of the base body 10, and at the moment, the hard disk locking assembly 100 is in a state capable of locking the hard disk 300. With the continuous force applied to the trigger 30, the link 43 drives the rocker 44 to swing, the rocker 44 contacts the actuator 20 through the portion other than the cam portion 441, the rocker slider mechanism is reset to the state when the trigger 30 is at the releasing position under the elastic force of the first elastic member 41, and the actuator 20 withdraws the inner cavity 11 under the action of the second elastic member 42, so that the hard disk locking assembly 100 is in a state capable of unlocking the hard disk 300.

Referring to fig. 4, and also referring to fig. 2 to 3, the guide member 12 is fixedly disposed on the inner wall of the base 10, and the guide member 12 is provided with a closed-loop guide groove 13, and the notch shape of the closed-loop guide groove 13 is a closed-loop strip-shaped pattern shown in fig. 4. A sliding end 431 at the end of the link 43 extends into the closed loop guide 13 and is in slidable contact with the guide 12. In the case of a plurality of successive presses of the trigger 30, the sliding end 431 can slide in the closed-loop guide groove 13 exactly in accordance with the pattern of the notches of the closed-loop guide groove 13 shown in fig. 4. The closed loop guide groove 13 includes the following three portions which are disposed in sequence and communicate with each other: a downshifting segment 131, a turning segment 132, and an upshifting segment 133.

The downshifting segment 131 and the upshifting segment 133 are directly connected to form an approximately inverted V-shaped pattern, the junction of the two (defined as the third junction) is the sharp corner of the V-shape, and the turning segment 132 itself approximates an inverted V-shaped pattern. The inverted V-shaped opening of the turning section 132 is connected with the inverted V-shaped opening formed by the downward moving section 131 and the upward moving section 133, namely, one end of the downward moving section 131 relatively far from the upward moving section 133 is communicated with one end of the turning section 132 in a crossing way, and one end of the upward moving section 133 relatively far from the downward moving section 131 is communicated with the other end of the turning section 132 in a crossing way; the sharp angle of the inverted V-shape of the turning section 132 has approximately the same orientation as the sharp angle of the inverted V-shape formed by the downward movement section 131 and the upward movement section 133, i.e., the bottoming position points in the direction of the releasing position.

In the closed loop guide slot 13, the turning section 132 is recessed in a direction pointing from the bottoming position to the releasing position to form a turning angle 135. The above-mentioned rocker-slide mechanism has a defined movement path, as well as for the individual components in the rocker-slide mechanism, so that the position of the trigger 30 on the pressing movement path corresponds to the position of the sliding end 431 in the closed-loop guide slot 13 as follows:

when the trigger 30 is at the releasing position, the sliding end 431 extends into the downward moving section 131 and stays in a region relatively close to the upward moving section 133 in the downward moving section 131;

when the trigger piece 30 is at the fixed position, the sliding end 431 extends into the turning section 132 and stays in the bending angle 135 area of the turning section 132;

when the trigger 30 is in the bottoming position, the sliding end 431 extends into the first junction between the downward moving section 131 and the turning section 132, or into the second junction between the upward moving section 133 and the turning section 132, depending on the position of the trigger 30 before reaching the bottoming position.

Referring to fig. 4, the inner wall of the outer edge of the turning section 132 forms a lifting angle 134, when the trigger 30 is pressed from the releasing position to the bottoming position for the first time, the sliding end 431 is located at the base of the lifting angle 134 relatively close to one side of the downward moving section 131, after that, pressing the trigger 30 is stopped, the trigger 30 is pushed by the first elastic member 41 and is reset along the direction approaching the fixed position and the releasing position, the sliding end 431 continues to move along the turning section 132 and is lifted to the turning angle 135 by the lifting angle 134, when the sliding end 431 reaches the turning angle 135, the trigger 30 reaches the fixed position, and at this time, the sliding end 431 is located at one side of the lifting angle 134 relatively close to the upward moving section 133.

When the trigger member 30 is at the fixed position, the potential energy of the first elastic member 41 at this time has a tendency to drive the trigger member 30 to move from the fixed position to the releasing position, and the sliding end 431 is just blocked by the inner wall of the inflection angle 135, so that the first elastic member 41 and the guide member 12 cooperate with each other at the inner edge of the inflection angle 135, so that the sliding end 431 is fixedly abutted against the inner wall of the inflection angle 135, and the connecting rod 43 is in a balanced state. Therefore, when the trigger member 30 is at the fixed position, the rocker slider mechanism is in a self-locking equilibrium state and remains fixed, and the rocker 44 also remains fixed in the angular state shown in fig. 8, so that the cam portion 441 can be ensured to continuously apply a holding force to the actuator 20 to maintain the state that the actuator 20 extends out of the seat 10.

To release the self-locking equilibrium state of the rocker slider mechanism, the trigger 30 needs to be pressed again and the trigger 30 is brought back to the bottoming position. When the sliding end 431 is fixedly abutted against the inner wall of the bending angle 135, the sliding end 431 is already at one side of the lifting angle 134 relatively close to the upward moving section 133, and then applies force to the trigger 30 again to press the trigger 30 to the bottoming position again, the sliding end 431 will continue to slide along one side of the lifting angle 134 relatively close to the upward moving section 133 and gradually approach the second intersection of the bending section 132 and the upward moving section 133, but will not slide along the opposite direction to one side of the lifting angle 134 relatively close to the downward moving section 131.

After the trigger 30 reaches the bottoming position again, the pressing force is removed, and the first elastic member 41 pushes the trigger 30 again to reset along the direction approaching the releasing position, in which the sliding end 431 slides along the up-moving section 133 and approaches the third junction of the down-moving section 131 and the up-moving section 133. When the trigger 30 finally stays in the release position, the sliding end 431 has entered the downshifting section 131, after which the trigger 30 is pressed, the sliding end 431 will slide along the downshifting section 131 and not in the opposite direction into the upshifting section 133. Thus, the slip direction of the slip end 431 within the closed loop guide slot 13 is uniquely defined.

Referring to fig. 7 to 8, the hard disk locking assembly 100 shown in fig. 7 is in a state of unlocking and separating from the hard disk 300, the trigger member 30 is in a releasing position, the actuator member 20 withdraws from the inner cavity 11 of the base 10, the distance from one end of the actuator member 20 abutting against the rocker 44 to the swinging center 442 is shortest, the hard disk locking assembly 100 shown in fig. 8 is in a state of locking and connecting with the hard disk 300, the trigger member 30 is in a fixed position, a part of the actuator member 20 extends out of the base 10, one end of the actuator member 20 abutting against the rocker 44 contacts the cam portion 441, the first elastic member 41 and the second elastic member 42 are in a compressed state, potential energy of the first elastic member 41 is greater than potential energy of the first elastic member 41 in the state shown in fig. 7, and potential energy of the second elastic member 42 is greater than potential energy of the second elastic member 42 in the state shown in fig. 7.

As shown in fig. 7, when the trigger 30 is in the release position, the two actuators 20 respectively abut against the rocker 44 except the two cam portions 441, and both are withdrawn from the seat 10; as shown in fig. 8, when the two actuators 20 are respectively abutted against the two cam portions 441, the two actuators 20 are both in a state of protruding out of the housing 10.

In the state shown in fig. 8, the compression amount of the second elastic member 42 is maximized, and when the trigger member 30 reaches the bottoming position, the compression amount of the first elastic member 41 is maximized, in other words, when the trigger member 30 is in the bottoming position, the sum of elastic potential energies Q1 of the first elastic member 41 and the second elastic member 42, and when the trigger member 30 is in the stationary position, the sum of elastic potential energies Q2 of the first elastic member 41 and the second elastic member 42, Q1 > Q2. When the trigger member 30 is at the bottoming position, the potential energy accumulated by the first elastic member 41 is sufficient to drive the sliding end 431 to leave the turning section 132 and enter the upward moving section 133.
