In some embodiments, referring to fig. 1 to 3, the third elastic buckle 30 of the fastening mechanism is disposed between the first elastic buckle 10 and the second elastic buckle 20, the second plate portion 21 is provided with a first protrusion 211 on a side facing the first elastic buckle 10, the pushing portion 31 is provided with a second protrusion 312, and the second protrusion 312 is configured to interfere with the first protrusion 211 along a rebound direction of the pushing portion 31 when the first engaging portion 11 and the second engaging portion 22 are engaged, so that when the pushing portion 31 rebounds, the second protrusion 312 can push against the first protrusion 211 to move in a direction away from the first elastic buckle 10, thereby separating the first engaging portion 11 and the second engaging portion 22. Specifically, when the press-contact portion 32 receives external pressure, the pushing portion 31 compresses the third elastic member, and the second protrusion 312 moves along with the third elastic member, so that the second protrusion 312 is separated from the first protrusion 211, and at this time, the second elastic buckle 20 rebounds under the elastic force of the second elastic member, so that the second engaging portion 22 can be engaged with the first engaging portion 11, thereby locking the first elastic buckle 10 at the unlocking position, and facilitating the external device to be taken down; in addition, after the external pressure applied to the press-contact portion 32 is released, the pushing portion 31 rebounds under the action of the third elastic member, the second protrusion 312 pushes the first protrusion 211 to move, and further drives the second engaging portion 22 to separate from the first engaging portion 11, so that the engagement connection between the first elastic buckle 10 and the second elastic buckle 20 is released, and the first elastic buckle 10 returns to the locking position under the action of its own resilience.

In some embodiments, referring to fig. 1 to fig. 3, the first protrusion 211 of the locking mechanism is provided with a first guiding surface 2111, and the first guiding surface 2111 is configured to slidably cooperate with the second protrusion 312 to guide the first protrusion 211 to move away from the first elastic buckle 10. Specifically, the first guide surface 2111 is provided so that the second protrusion 312 is separated and displaced from the first protrusion 211 more easily, and the second engaging portion 22 is separated from the first engaging portion 11 more easily, so that the engaging connection between the first buckle 10 and the second buckle 20 is released more easily, and the use of the entire buckle mechanism is smoother.

In another embodiment, the first engaging portion 11 may be a buckle formed on the first board portion 12, and the second engaging portion 22 is a slot formed on the second board portion 21, so that the first elastic buckle 10 and the second elastic buckle 20 are engaged and fixed by the cooperation of the buckle and the slot; of course, in other embodiments, the first engaging portion 11 and the second engaging portion 22 may have other engaging structures, which are not described herein again.

The operation of the latch mechanism in this embodiment is explained with reference to fig. 1 to 3, and the latch mechanism has an initial state, a locked state, and an unlocked state, which are described below:

when the buckle mechanism is in the initial state, no external force acts on the third elastic buckle 30, the second protrusion 312 of the third elastic buckle 30 pushes the first protrusion 211 of the second elastic buckle 20 to move in the direction away from the first elastic buckle 10, so that the second engaging portion 22 of the second elastic buckle 20 is located outside the first engaging portion 11, and the first elastic buckle 10 is in the locking position under the action of the first elastic member.

When the buckle mechanism is in a locked state, that is, the first elastic buckle 10 is in a locked position under the action of the first elastic member and is in buckle connection with the external device, at this time, the external device is pressed on the press-contact portion 32 of the third elastic buckle 30 and drives the pushing portion 31 to move in a direction away from the second elastic buckle 20, so that the second protrusion 312 is separated from the first protrusion 211, the second elastic buckle 20 is elastically abutted against one side of the first elastic buckle 10 where the first engaging portion 11 is disposed under the action of the second elastic member, but the second engaging portion 22 is not in contact with the first engaging portion 11.

When this buckle mechanism is in the unblock state, when external equipment needs to separate with first bullet knot 10 promptly, when moving unlocking position with first bullet knot 10 from the locking position, second bullet knot 20 is connected with first bullet knot 10 buckle this moment, second block portion 22 of second bullet knot 20 is connected with first block portion 11 block of first bullet knot 10 under the resilience force of second elastic component promptly, at this moment, second bullet knot 20 locks first bullet knot 10 in unlocking position, first bullet knot 10 can't kick-back, make things convenient for takeaway of external equipment.

After the external device is taken away, the press-contact force applied to the third elastic buckle 30 is released, and at this time, the third elastic buckle 30 moves under the resilience force of the third elastic member, and the second protrusion 312 pushes the first protrusion 211, so that the second engaging portion 22 of the second elastic buckle 20 moves out from the first engaging portion 11, thereby releasing the engaging connection between the first elastic buckle 10 and the second elastic buckle 20, i.e., returning to the initial state.

Referring to fig. 4 to 6, the present embodiment further provides a power module 50, which includes a housing 51, a battery pack (not shown) and the fastening mechanism, where the housing 51 has a first mounting cavity 5101 and a second mounting cavity 5102, the battery pack is assembled in the first mounting cavity 5101, and a first elastic buckle 10, a second elastic buckle 20 and a third elastic buckle 30 of the fastening mechanism are assembled in the first mounting cavity 5101.
