[0036] In order to make the purpose, technical solutions and advantages of the present disclosure more apparent, the following will describe in detail exemplary embodiments of the present disclosure with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments of the present disclosure, and it should be understood that the present disclosure is not limited to the exemplary embodiments described herein.

[0037] Example 1

[0038] Please refer to Figure 1 and Figure 2 This embodiment provides a push-lock folding mechanism, which includes a first connector 1 and a second connector 2. In a specific implementation, the first connector 1 and the second connector 2 are used to connect the drone's arm and the drone's body, respectively.

[0039] In a specific implementation, the first connecting member 1 is hinged to the second connecting member 2 ; in a specific implementation, the side edge of one end of the first connecting member 1 is hinged to the side edge of the second connecting member 2 .

[0040] Specifically, the first connecting member 1 is provided with a first clamping portion 11, the second connecting member 2 is provided with a claw 3, and the claw 3 is provided with a second clamping portion 31. In a specific implementation, the second clamping portion 31 is provided on the side of the second connecting member 2.

[0041] The first engaging portion 11 is capable of engaging with the second engaging portion 31. In a specific implementation, the second engaging portion 31 is a surface perpendicular to the length direction of the claw. In a specific implementation, the claw 3 is an L-shaped structure. The first engaging portion 11 is a stepped surface, wherein the stepped surface is perpendicular to the length direction of the first connector 1.

[0042] In a specific implementation, the first connecting member 1 and the second connecting member 2 have at least two states:

[0043] In the first state, please refer to Figure 1 The first engaging portion 11 engages with the second engaging portion 31, and the first connector 1 and the second connector 2 remain locked. In this state, the first connector 1 and the second connector 2 cannot rotate relative to each other, and the second connectors 2 no longer rotate relative to each other, allowing the arms to be deployed.

[0044] In the second state, please refer to Figure 2, the first clamping portion 11 is disengaged from the second clamping portion 31, and the first connecting member 1 and the second connecting member 2 can be folded. In this state, the second connecting members 2 can rotate relative to each other, making it easier to fold the arm.

[0045] In a specific implementation, the middle part of the claw 3 is hinged to the second connecting member 2; in a specific implementation, the middle part of the claw 3 protrudes toward the second connecting member 2. In this way, the claw 3 forms a fulcrum at the hinge, so that the claw 3 forms a lever mechanism, so that the pressure-type lock folding mechanism can be controlled by pressing, which facilitates the control between the first state and the second state.

[0046] The hinge centers of the first and second connectors 1 and 2 are arranged parallel to the centerline of the claws 3 and are located on opposite sides of the second connector 2 at one end close to the first connector 1. In this way, the claws 3 can further tighten the first and second connectors 1 and 2.

[0047] In a specific implementation, in order to facilitate the control of the claw 3 to achieve locking and unlocking of the first connecting member 1 and the second connecting member 2, the claw 3 is provided with a pressing portion 32, and the hinged position of the claw 3 is located between the second engaging portion 31 and the pressing portion 32. In this way, the claw 3 can form a lever structure. When in the first state, by pressing the pressing portion 32, the claw 3 can be released from the engaging state with the first connecting member 1.

[0048] For specific implementation, please refer to Figure 1 In order to ensure stable engagement of the claw 3 in the first state, an elastic member 4 is further included. The elastic member 4 is installed between the pressing portion 32 and the second connecting member 2. The elastic member 4 is used to abut the second engaging portion 31 of the claw 3 against the first engaging portion 11, thereby limiting relative rotation between the first connecting member 1 and the second connecting member 2. Specifically, the elastic member 4 is compressive and elastic. The elastic member 4 is used to press the second engaging portion 31 of the claw 3 toward the upper direction of the first connecting member 1, thereby enabling the first engaging portion 11 to hinder relative rotation between the first connecting member 1 and the second connecting member 2, thereby achieving stable locking between the first connecting member 1 and the second connecting member 2.

[0049] In a specific implementation, to facilitate the switching of the push-lock folding mechanism from the second state to the first state, a first guide portion 33 is provided on the end of the claw 3 proximate to the first connector 1. When the push-lock folding mechanism switches from the second state to the first state, the first connector 1 is directly rotated. During the rotation, the first connector 1 abuts against the first guide portion 33, driving the claw 3 to open outward until the first engaging portion 11 engages with the second engaging portion 31. Furthermore, to facilitate sliding movement with the first guide portion 33, a second guide portion 12 is provided on the edge of the first engaging portion 11 near the hinge center of the claw 3. During the switching of the push-lock folding mechanism from the second state to the first state, when the first connector 1 rotates, the second guide portion 12 contacts the first guide portion 33, generating a lateral force that causes the second engaging portion 31 of the claw 3 to open outward until the second engaging portion 31 engages with the first engaging portion 11.

[0050] In a specific implementation, in order to enable the first connecting member 1 to quickly open with the second connecting member 2 when switching from the first state to the second state, an avoidance hole 34 is provided on the claw 3 during the implementation process. The second connecting member 2 is also provided with a pressing member 21, which extends toward the direction close to the first connecting member 1; the function of the pressing member 21 is that when the claw 3 is pressed, the pressing member 21 can generate a small lateral force to cause relative rotation between the first connecting member 1 and the second connecting member 2. Specifically, in the first state, the pressing member 21 is located in the avoidance hole 34, and the pressing member 21 rests on the first connecting member 1. In a specific implementation, the avoidance hole 34 can also play a role in reducing weight.

[0051] In practice, to facilitate secure connection to the arm and body, the first connector 1 is provided with a sleeve 13 for connecting to the arm. The second connector 2 is provided with an outwardly extending connecting rod 22, which is provided with a connecting hole 23. The provision of connecting hole 23 facilitates bolt connection to the body.

[0052] In a specific implementation, a connecting ear 24 is provided at one end of the second connecting member 2 close to the first connecting member 1, and the connecting ear 24 is rotatably connected to the first connecting member 1 via a connecting shaft. That is, the connecting ear 24 and the first connecting member 1 can rotate relative to each other.

[0053] In a specific implementation, the pressing portion 32 is provided with anti-slip grooves on the side facing away from the second connector 2. Thus, by providing the anti-slip grooves, it is easy to press the claws to achieve the switching of the press-type lock folding mechanism from the first state to the second state.

[0054] In a specific implementation, in order to achieve the purpose of lightweighting, both the first connecting member 1 and the second connecting member 2 are provided with weight-reducing holes.

[0055] Example 2

[0056] This embodiment is a specific application of embodiment 1, and the similarities are not repeated here. Only the differences are described below.

[0057] This embodiment provides a drone, which includes the push-lock folding mechanism described in Example 1, wherein the first connector 1 is used to connect the drone's arm, and the second connector 2 is used to connect the drone's body. In a specific implementation, the drone's arm can be switched between the first and second states by controlling the push-lock folding mechanism to switch between the first and second states. During the switching process from the first state to the second state, the second state can be switched by simply pressing the pressing portion 32 of the claw 3. During the switching process from the second state to the first state, the first connector 1 can be simply rotated toward the second connector 2 until the first engaging portion 11 engages with the second engaging portion 31.
