Fig. 6 is a partial schematic structural diagram of a locking mechanism 505 according to an embodiment of the present invention at a first viewing angle. Referring to fig. 4 to 6, in the embodiment, when the driving element 521 moves to the triggering position, the driving element 521 drives the transmission element 511 to move so as to move the locking assembly 507 to the unlocking state. Specifically, the driving element 521 includes a driving surface 523, the transmission element 511 includes a transmission surface 513, when the driving element 521 is located at the initial position, the driving surface 523 is spaced from the transmission surface 513, and when the driving element 521 moves from the initial position to the triggering position and the limiting element 525 moves along with the driving element 521 and exits from the movement path of the transmission element 511, the driving surface 523 abuts against the transmission surface 513 to drive the transmission element 511 to move, so that the locking assembly 507 moves to the unlocking state. In other embodiments of the present invention, when the driving element 521 moves from the initial position to the triggering position, the driving element 521 drives the limiting element 525 and the transmission element 511 to move simultaneously, so that the limiting element 525 exits from the movement path of the transmission element 511, and the transmission element 511 moves to move the locking assembly 507 to the unlocking state. The sequence of the driving member 521 driving the limiting member 525 and the driving member 511 is not particularly limited in this embodiment, as long as the driving member 521 driving the driving member 511 drives the locking hook 509 to separate from the locking portion 519.

In other embodiments of the present invention, the limiting member 525 is located on the movement path of the locking hook 509, and prevents the locking hook 509 from being separated from the locking portion 519, so that the locking assembly 507 is locked in the locking state, or the limiting member 525 is located outside the movement path of the transmission member 511, and when the limiting member 525 is located at the working position, the limiting member 525 is inserted into or engaged with the transmission member 511, and prevents the transmission member 511 from moving so that the locking assembly 507 is locked in the locking state.

In this embodiment, when the first frame 501 is in the open position, the driving member 521 is in the initial position, under the action of the elastic reset member 517, the locking assembly 507 is in a locking state, and at this time, the locking hook 509 is separated from the locking portion 519, when the first frame 501 rotates from the open position to the closed position, the locking hook 509 first contacts the locking portion 519, as the first frame 501 continues to rotate, the locking hook 509 moves under the action of the locking portion 519 against the action force of the elastic restoring member 517 to move the locking assembly 507 to the unlocking state, the transmission member 511 pushes the limiting member 525 to separate from the working position against the elastic force of the elastic member 531, after the transmission member 511 passes over the limiting member 525, the elastic restoring member 517 causes the locking hook 509 to cooperate with the locking portion 519, that is, the locking assembly 507 moves to the locking state, the elastic member 531 resets the limiting member 525 to the working position, and the limiting member 525 abuts against the limiting portion 545 to automatically lock the locking assembly 507 in the locking state. The arrangement is such that when the first frame 501 is closed, the operation of the driving element 521 is not required, and the locking of the first frame 501 can be automatically completed under the action of the elastic element 531 and the elastic restoring element 517, the operation is simple, and the limiting part 545 limits the movement of the limiting element 525 relative to the driving element 521, so that the limiting element 525 can lock the locking assembly 507 in the locked state more reliably.

In other embodiments of the present invention, the locking hook 509 is made of an elastic material, for example, the locking hook 509 is a metal spring, and under the elastic force of the locking hook 509, the locking component 507 always has a tendency to move to the locking state.

Optionally, with continued reference to fig. 4 and fig. 5, the locking assembly 507 is rotatably disposed on the first frame 501, the limiting element 525 is pivotally connected to the driving element 521 through a pivot shaft 543, the limiting element 525 can rotate around the pivot shaft 543 relative to the driving element 521, when the driving element 521 is located at the initial position, the limiting element 525 is located at the working position under the action of the elastic element 531, when the first frame 501 rotates from the open position to the closed position, the driving element 511 rotates and drives the limiting element 525 to rotate in a direction away from the working position against the elastic force of the elastic element 531, so that the limiting element 525 exits from the movement path of the driving element 511, and when the driving element 511 passes over the limiting element 525 to engage the locking hook 509 with the locking portion 519, the elastic element 531 rotates the limiting element 525 to the working position. In other embodiments of the present invention, the locking assembly 507 is movably disposed on the first frame 501, and the limiting member 525 is movably disposed on the driving member 521.

Alternatively, when the driving member 521 is located at the initial position, the axis of the pivotal shaft 543 is parallel to the rotation axis of the locking assembly 507. With such an arrangement, when the first frame 501 is closed, the driving member 511 can more smoothly pass over the limiting member 525 to engage the locking hook 509 with the locking portion 519, thereby further improving the smoothness when the first frame 501 is closed.

Referring to fig. 4 and fig. 5, in the embodiment, the limiting element 525 is movably disposed on the driving element 521, the elastic element 531 is connected between the limiting element 525 and the driving element 521, and the limiting portion 545 is fixedly disposed on the driving element 521. The arrangement enables the driving member 521 to more reliably drive the limiting member 525 to move from the initial position to the trigger position so as to unlock the state of the locking assembly 507, the limiting portion 545 is disposed on the driving member 521 so that the driving member 521 drives the limiting member 525 to move, the limiting portion 545 moves along with the limiting member 525, and therefore the reliability of the abutting joint of the limiting member 525 and the limiting portion 545 is improved, and the arrangement is further beneficial to realizing the modular installation of the locking mechanism 505.

Alternatively, when the first frame 501 is located at the closing position, the locking assembly 507 is located at the locking state, the driving element 521 is located at the initial position, and the limiting element 525 is located at the working position, the driving element 511, the limiting element 525, and the limiting portion 545 are sequentially arranged along the rotation direction of the limiting element 525. The arrangement is such that when the locking assembly 507 locks the first frame 501 at the closing position and the locking assembly 507 is vibrated due to falling or the like, the transmission member 511 can abut against the limiting member 525, and the acting force of the transmission member 511 on the limiting member 525 causes the limiting member 525 to abut against the limiting portion 545, so that the limiting member 525 is more reliably maintained at the working position, and the locking reliability of the locking mechanism 505 on the first frame 501 is improved.
