[0029] Example

[0030] like Figure 1-3As shown, the autonomous emergency energy breaker of the drone includes a drone frame 2000 and an emergency energy breaker structure 1000 arranged on the side wall of the drone frame 2000; the emergency energy breaker structure 1000 is composed of a spring base 1100 arranged on the inner side of the side wall of the drone frame 2000, a switch frame 1200 arranged on the outer side of the side wall of the drone frame 2000 and cooperating with the spring base 1100, a movable frame 1300 cooperating with the switch frame 1200, a battery female connector 1400 arranged on the side wall of the drone frame 2000, and a battery male connector 1500 arranged on the movable frame 1300 and cooperating with the battery female connector 1400.

[0031] The drone frame is an existing technology. When it is installed and used, modules or components such as a control module, a drive module, a positioning module, a propeller, a propeller bracket, and a leg will be set on it. The emergency energy-off structure needs to be connected to the control module and the power supply model when in use. After receiving the instruction from the control module, it will run and disconnect the male power plug and the female power plug. Its power supply and control methods are all existing technologies in this field. Those skilled in the art can complete its setting and use based on the above description without creative labor, so they will not be elaborated here.

[0032] The spring base 1100 is composed of a bottom plate 1110 fixed inside the drone frame 2000 and parallel to the side wall of the drone frame 2000, a limiting seat barrel 1120 arranged on the side wall of the bottom plate 1110 facing the side wall, and a spring 1130 arranged on the limiting seat barrel 1120.

[0033] The base plate can be fixed inside the drone frame. The fixing method can be fixed by a slot, an adhesive, a snap fastener, a screw, etc. Those skilled in the art can select the corresponding fixing method according to the actual drone frame structure to complete the fixing of the base plate, which will not be described in detail here.

[0034] There are four limiting seat barrels 1120 , and the four limiting seat barrels 1120 are respectively arranged at the four corners of the side wall of the bottom plate 1110 facing the side wall; the limiting seat barrel 1120 is provided with a limiting slot hole with a diameter greater than or equal to the outer diameter of the spring 1130 .

[0035] The switch frame 1200 consists of two U-shaped frames 1210 symmetrically arranged on the left and right sides of the battery female connector 1400, and the rear side bars are fixed to the side walls of the drone frame 2000 by fixing screws and nuts 1220, and two electromagnetic switches 1230 relatively arranged on the upper and lower side bars of the U-shaped frame 1210; two spring holes 1211 with diameters and positions matching the limit slots are provided on the rear side bars of the U-shaped frame 1210, and a fixing hole 1212 that cooperates with the fixing screws and nuts 1220 is also provided between the two spring holes 1211.

[0036] The electromagnetic switch 1230 consists of an electromagnetic relay 1231, a movable rod 1232 arranged at the front end of the electromagnetic relay 1231, a return spring 1233 which is sleeved on the movable rod 1232, the front end of which is fixed on the outer wall of the movable rod 1232 and the rear end is fixed on the electromagnetic relay 1231, a sloped locking head 1234 arranged at the front end of the movable rod 1232, a pop-up limit ring 1235 which is sleeved on the outside of the movable rod 1232 and located between the return spring 1233 and the sloped locking head 1234, and a retraction limit ring 1236 which is sleeved on the outside of the movable rod 1232 and located between the pop-up limit ring 1235 and the sloped locking head 1234.

[0037] The material of the movable rod can be any material that can be attracted by a magnet, such as iron, cast iron, etc.

[0038] The electromagnetic relay 1231 is arranged on the outer side of the side bar of the U-shaped frame 1210, the sloped lock head 1234 passes through the side bar and extends from the inner side of the side bar, and the pop-up limit ring 1235 and the retraction limit ring 1236 are both fixed in the channel on the side bar penetrated by the sloped lock head 1234.

[0039] When setting, the slope of the slope lock head needs to face the opening direction of the U-shaped frame.

[0040] When the electromagnetic switch is not energized, the reset spring will extend and push the movable rod outward until the end of the reset spring touches the pop-up limit ring. At this time, the sloped lock head extends outward from the inner side of the side bar. When the movable frame is pushed into the U-shaped frame and passes through the sloped lock head, the sloped lock head is pressed outward into the side bar. After the movable frame passes, the sloped lock head pops out again under the action of the reset spring and uses the flat surface at the bottom to limit the movable frame from detaching outward from the U-shaped frame.

[0041] When the control module or remote controller sends a command to energize the electromagnetic switch, the electromagnetic relay is energized to generate a magnetic field, causing the movable rod to compress the spring under the action of the magnetic force to move toward the electromagnetic relay, thereby driving the sloped lock head to retract the side bar until the sloped lock head contacts the retraction limit ring. At this time, the sloped lock head is completely retracted into the side bar, allowing the movable frame to move toward the opening of the U-shaped frame.

[0042] The movable frame 1300 is composed of two symmetrically arranged vertical clamping plates 1310, a horizontal clamping plate 1320 arranged parallel to the two vertical clamping plates 1310, two matching blocks 1330 respectively arranged on the rear sides of the two vertical clamping plates 1310, and a spring slot 1340 arranged on the rear side of the matching blocks 1330.

[0043] The width of the vertical clamping plate 1310 is the same as the distance between the two side bars on the U-shaped frame 1210 , the width of the spring slot 1340 is greater than or equal to the outer diameter of the spring 1130 , and the distance between the horizontal clamping plates 1320 matches the battery male connector 1500 .

[0044] The spring 1130 passes through the spring hole 1211 and the side wall of the drone frame 2000 at the same time, and the front end of the spring 1130 extends into the spring groove 1340 and abuts against the bottom of the spring groove 1340, and the rear end extends into the limiting slot and abuts against the bottom of the limiting slot.

[0045] When in use, first make the front end of the spring rest against the bottom of the spring groove, push the movable frame and the power male connector into the U-shaped frame until the movable frame is restricted in the U-shaped frame by the electromagnetic switch and the power male connector and the power female connector are matched. At this time, the power supply connected to the power female connector can supply power to the outside normally; when it is necessary to cut off the power supply, the controller sends a command to energize the electromagnetic switch, so that the electromagnetic switch no longer restricts the movable frame, and the movable frame is separated from the U-shaped frame outward under the action of the spring. When separating, the movable frame pushes the power male connector outward, and finally the power male connector and the power female connector are separated, thereby completing the power cut-off of the drone.

[0046] It should be noted that all features disclosed in this specification, or steps in all methods or processes disclosed, except for mutually exclusive features and / or steps, can be combined in any manner.

[0047] In addition, the above-mentioned specific embodiments are merely illustrative.
