[0037] The following is a further description of the drone arm contact type connection device provided in the embodiment of the present application: In the drone arm contact type connection device provided in the embodiment of the present application, the first end of the main arm body 11 of the arm mechanism 10 is provided with a power device 20, and the second end of the main arm body 11 is provided with a connecting male socket 12, the connecting male socket 12 extends into the installation cavity 313 of the fixing frame 31, and the second contact head 13 on the connecting male socket 12 is respectively electrically contacted with each first contact head 321 of the connecting female socket 32, so that the power device 20 can be electrically connected to the relevant electrical components in the drone fuselage through the electrical contact cooperation between the connecting male socket 12 and the connecting female socket 32. The connection is realized, thereby providing flight power for the UAV, and since the opening position of each first contact head 321 of the connecting female socket 32 ​​is the opening facing away from the installation cavity 313, and the setting position of each second contact head 13 of the connecting male socket 12 is the opening facing the installation cavity 313, when the connecting male socket 12 and the connecting female socket 32 ​​are electrically connected, the connecting male socket 12 can achieve effective limiting of the second end of the main arm body 11 in the installation cavity 313 by abutting against the connecting female socket 32, which improves the connection stability between the main arm body 11 and the fixing frame 31 on the one hand, and ensures the electrical connection stability between the connecting male socket 12 and the connecting female socket 32 ​​on the other hand.

[0038] In other embodiments of the present application, Figure 3 and Figure 4 As shown, the upper end of the connecting female seat 32 protrudes to form a connecting boss 322, and each first contact head 321 is formed on the side of the connecting boss 322 away from the outlet. The connecting male seat 12 is provided with an assembly groove 121, and the connecting boss 322 is embedded in the assembly groove 121. Each second contact head 13 is arranged on a side groove wall of the assembly groove 121 facing each first contact head 321.

[0039] Specifically, by providing the connecting boss 322 and the assembly groove 121, and making the connecting boss 322 embedded in the assembly groove 121, the abutment matching stability of the connecting female seat 32 and the connecting male seat 12 is significantly improved, thereby further improving the electrical connection stability of the connecting male seat 12 and the connecting female seat 32 and the connection stability between the main arm body 11 and the fixing frame 31.

[0040] In other embodiments of the present application, Figure 4 As shown, the connecting male seat 12 is provided with an assembly cavity 122, and the second end of the main arm body 11 is disposed in the assembly cavity 122. The outer wall of the connecting male seat 12 is protruded to form two protrusions 123 arranged at intervals, and an adjustment groove 124 is formed between the two protrusions 123. The adjustment groove 124 and the assembly cavity 122 are connected, and the two protrusions 123 are connected by a locking bolt 125.

[0041] Specifically, an adjustment groove 124 which is connected to the assembly cavity 122 is provided between the two protrusions 123, and the width of the adjustment groove 124 can be adjusted by adjusting the tightness of the locking bolt 125 connected to the two protrusions 123, thereby effectively adjusting the size of the assembly cavity 122. In this way, the connection strength between the second end of the main arm body 11 and the connecting male seat 12 can be adjusted by the locking degree of the locking bolt 125, and quick disassembly and assembly without tools of the main arm body 11 and the connecting male seat 12 can also be achieved.

[0043] Specifically, by setting a guide shaft 14 and making the guide shaft 14 pass through the opposite sides of the connecting male seat 12, the two ends of the guide shaft 14 are respectively slidably set in the guide grooves 311 on the opposite side walls of the installation cavity 313. In this way, when the connecting male seat 12 is inserted into the installation cavity 313, it can be quickly and accurately inserted into the installation cavity 313 under the guiding action of the guide shaft 14, thereby improving the assembly efficiency of the drone arm contact type connection device.

[0045] Specifically, the main arm body 11 is firstly arranged in the clamping area 35, and the second side of the second clamp 34 is rotated to the buckling side of the first clamp 33 and buckled with the buckling side. In this way, the first clamp 33 and the second clamp 34 are used to tighten the main arm body 11, and by tightening the main arm body 11 with the first clamp 33 and the second clamp 34, on the one hand, the main arm body 11 is firmly limited, and on the other hand, the convenience of disassembling the main arm body 11 relative to the fixing frame 31 is improved.

[0046] In other embodiments of the present application, Figure 6As shown, a buckling groove (not shown) is provided on the buckling side in a direction away from the installation side, and a buckling column 36 is provided on the second side, and the buckling column 36 is used to buckle in the buckling groove. Specifically, the buckling connection between the buckling side of the first clamp 33 and the second side of the second clamp 34 is completed by utilizing the cooperation of the buckling column 36 and the buckling groove. In this way, on the one hand, the first clamp 33 and the second clamp 34 can be quickly tightened on the main arm body 11. On the other hand, since the buckling groove is provided in the direction away from the installation side of the buckling side, the matching stability of the buckling column 36 and the buckling groove is also guaranteed, so that the buckling column 36 is not easy to loosen from the buckling groove.

[0047] In other embodiments of the present application, Figure 6 As shown, the first side protrudes in a direction away from the second side to form an angle piece 37. Specifically, by arranging the angle piece 37 on the first side in a direction away from the second side, the operator can achieve the clamping engagement or release of the first clamping member 33 and the second clamping member 34 by pulling the angle piece 37, thereby making the use of the clamp mechanism simple and convenient.

[0048] In other embodiments of the present application, Figure 1 and Figure 2 As shown, the arm mechanism 10 further includes a fixing seat 15 and a leg support mechanism (not shown), the fixing seat 15 is arranged at the first end of the main arm body 11, and the power device 20 and the leg support mechanism are both fixed to the fixing seat 15.
