Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, in particular to an external power supply system for unmanned aerial vehicles. Background Art

[0002] With the development of unmanned aerial vehicle technology, its application scope is becoming more and more extensive; for example, ordinary people commonly use photography, configure a camera on a rotor unmanned aerial vehicle, remotely control the unmanned aerial vehicle to cruise through a mobile phone or the like, and simultaneously perform shooting; for example, for building inspection and maintenance, etc., it is necessary to configure an extension arm on the rotor unmanned aerial vehicle, and even configure a suction cup structure at the front end of the extension arm to extend and adsorb and fix on the building surface and perform inspection operations; for example, lift an object and throw it at a designated position.

[0003] Generally, an unmanned aerial vehicle in the market includes a fuselage, a frame, a landing leg, a support arm, a rotor, etc., and is configured with a control system and a power supply, and can remotely control the unmanned aerial vehicle to take off through remote control or a mobile phone or the like, and then cruise, perform operations, return, and land.

[0004] For example, in the Chinese patent document "Landing Unmanned Aerial Vehicle Landing Gear and Unmanned Aerial Vehicle with the Publication Number of CN219884123U", each lower pressure rod of the landing gear forms a landing fulcrum to approach and contact the ground directly below it vertically and is fixed to support the unmanned aerial vehicle body, realizing horizontal landing on uneven and irregular ground.

[0005] As described above, generally, an unmanned aerial vehicle is configured with a power supply. However, during the operation in the wild, the unmanned aerial vehicle needs to continuously consume power. If it encounters unexpected situations and the operation time is extended, the power of the unmanned aerial vehicle will be consumed too quickly, and then it will be difficult for the unmanned aerial vehicle to complete the return flight or continue to complete the operation.

[0006] In addition, outdoor operation devices such as flood monitoring devices, landslide monitoring devices, forest fire monitoring devices, crop monitoring devices, or meteorological monitoring devices need to continuously consume power during standby and operation. If they encounter unexpected situations and the operation time is extended, the power of the outdoor operation devices will be consumed too quickly, and then it will be difficult for the outdoor operation devices to continue to complete the operation. Summary of the Utility Model

[0007] The object of the present invention of the utility model is to provide an external power supply system for unmanned aerial vehicles, which can charge an operation unmanned aerial vehicle landing in the wild or an outdoor operation device in view of the above problems.

[0008] To achieve the above object, the technical solution adopted by the utility model is:

[0009] External battery charging system for unmanned aerial vehicle, comprising an external battery pack and the unmanned aerial vehicle body. The unmanned aerial vehicle body is configured with a throwing mechanism, and the external battery pack is suspended on the throwing mechanism, and the external battery pack can be thrown under the control of the unmanned aerial vehicle body. It further comprises a power connection component, which includes conductive sheet I, conductive sheet II, socket seat and fixed seat. The fixed end of the socket seat is arranged on the outer side wall of the external battery pack, the socket seat is provided with conductive sheet I, the fixed end of the fixed seat is arranged on the object to be wired, the fixed seat is provided with conductive sheet II, the socket seat can be sleeved on the connection end of the fixed seat under the action of external force, and the socket seat or the fixed seat is provided with a flared opening, and the flared opening gradually contracts from outside to inside for socketing and guiding. And when the socket seat is sleeved on the fixed seat, conductive sheet I is in contact connection with conductive sheet II. Conductive sheet I is electrically connected to the external battery pack through wire I, and conductive sheet II is electrically connected to the circuit of the object to be wired through wire II.

[0010] Wherein, the power connection component further includes terminal I and terminal II. The I end of terminal I is connected to conductive sheet I, the II end of terminal I is connected with wire I, the I end of terminal II is connected to conductive sheet II, and the II end of terminal II is connected with wire II. In this way, quick wiring can be achieved through the terminals. Wherein, the object to be wired is an operating unmanned aerial vehicle or outdoor operating equipment. Conductive sheet II is electrically connected to the circuit of the operating unmanned aerial vehicle or outdoor operating equipment through wire II. In this way, control the unmanned aerial vehicle body to slowly descend with the external battery pack, and control to align the socket seat with the fixed seat for socketing. After the socketing is completed, control the throwing mechanism to throw the external battery pack to charge the operating unmanned aerial vehicle or outdoor operating equipment landing in the wild.

[0011] As described above, the unmanned aerial vehicle body is configured with a throwing mechanism to install the external battery pack and make it be thrown under the control of the unmanned aerial vehicle body. A socket seat is arranged on the outer side wall of the external battery pack, a fixed seat is arranged on the object to be wired, and the socket seat or the fixed seat is provided with a flared opening for socketing and guiding to form an alignment error space. The unmanned aerial vehicle body flies to a position where the socket seat and the fixed seat can be aligned and sleeved, and then descends to complete the socketing of the socket seat and the fixed seat. After the socketing is completed, control the throwing mechanism to throw the external battery pack to achieve charging of the operating unmanned aerial vehicle or outdoor operating equipment landing in the wild.

[0012] Based on the foregoing solution, in an improved solution, in order to improve the stability of the contact connection between the conductive sheet I and the conductive sheet II, in this external power supply replenishment system of the drone, the power supply interconnection component further includes a locking member. The locking member is arranged on the fixed seat or the object to be wired, and when the socket is sleeved on the fixed seat, it can press the socket tightly against the fixed seat; in this way, after the sleeving is in place, the locking member locks, so that the conductive sheet I and the conductive sheet II are in close contact connection. Preferably, the locking member is an electric control lock. The fixed end of the fixed seat is arranged on the outer side wall of the housing of the object to be wired. The electric control lock can be arranged inside the housing of the object to be wired, and the lock tongue of the electric control lock can penetrate a certain length out of the housing of the object to be wired to press the socket tightly against the fixed seat; in this way, compared with the mechanical locking structure of the elastic convex component, it is more labor-saving to pull out the socket by using the electric control lock.

[0013] Based on the foregoing solution, in an improved solution, in order to increase the throwing range of the external battery and reduce the influence on the object to be wired during the throwing process, this external power supply replenishment system of the drone further includes a sliding bolt member. The sliding bolt member includes a sliding rail and a sliding block. The lower end of the sliding rail is arranged on the outer side wall of the external battery pack.

There is an assembly port at the upper end of the track, and the sliding block can slide into or out of the assembly port under the action of an external force; in this way, the detachable connection between the socket and the external battery pack is realized, and then through a certain length of wire I connected externally, the external battery pack can move and be thrown within a large range. In a preferred example, in order to limit the socket to prevent it from easily slipping out of the sliding rail, this sliding bolt member further includes an elastic protruding member. The elastic protruding member is arranged at the assembly port of the track. The elastic protruding member protrudes into the track in the initial natural state to block the sliding block, and the elastic protruding member is compressed to vacate the track when the sliding block is squeezed by a certain external force; in this way, the elastic protruding member can limit the sliding block, and it can slide into or out of the assembly port after the sliding block is squeezed by an external force value above a certain value.

[0036] Embodiment 1

[0037] Refer to Figures 1 - 9 For the external power supply system for drones of Embodiment 1 of the present utility model, it includes an external battery pack 4 and a drone body (power supply replenishing drone) 200. The drone body 200 is configured with a throwing mechanism 202. The external battery pack 4 is suspended on the throwing mechanism 202, and the external battery pack 4 can be thrown under the control of the drone body. It further includes a power supply interconnection component. The power supply interconnection component includes a conductive sheet I 22, a conductive sheet II 12, a socket 2, and a fixed seat 1. The fixed end of the socket 2 is arranged on the outer side wall of the external battery pack 4. The socket 2 is provided with a conductive sheet I. The fixed end of the fixed seat 1 is arranged on the object to be wired. The fixed seat 1 is provided with a conductive sheet II. The socket 2 can be socketed on the connection end of the fixed seat 1 under the action of an external force. And the socket 2 or the fixed seat 1 is provided with a flared opening for socketing guidance. The flared opening gradually contracts from the outside to the inside (from the connection end to the fixed end). And when the socket is socketed on the fixed seat, the conductive sheet I and the conductive sheet II are in contact and connected with each other. The conductive sheet I is electrically connected to the external battery pack through a wire I, and the conductive sheet II is electrically connected to the circuit of the object to be wired through a wire II.

[0038] Among them, the UAV body includes a fuselage 201, a frame, landing gears, a support arm, rotors, etc. A delivery mechanism 202 is assembled under the fuselage 201. Inside the fuselage 201, there are a lithium battery pack and a circuit board of a controller, etc. The start and stop of the rotors and the throwing of the delivery mechanism (throwing device) are connected and controlled via standard cables. The UAV body and its control are both existing technologies and will not be elaborated here; for example, DJI UAVs on the market; another example is the Chinese patent document "A Landing UAV Landing Gear Mechanism and UAV, Publication No. CN219884123U", where each downward pressure rod of the landing gear forms a landing fulcrum to approach and contact the ground directly below it vertically and is fixed to support the UAV body, realizing a horizontal landing on uneven and irregular ground; another example is the Chinese patent document "A Crack Detection UAV, Publication No. CN216509120U". Taking the crack detection solution of a four-rotor UAV for a building as an example, a telescopic arm and a crack detection mechanism are arranged on the UAV body. The crack detection mechanism includes a mechanical working arm, a crack detector, etc., which can slide back and forth and extend along the telescopic arm, and then the crack detection is realized through the crack detector. It is equipped with landing gears for landing; another example is the Chinese patent document "A UAV with a Removable External Battery, Publication No. CN207956061U", which installs a body battery and a throwing device on the UAV body, and a removable external battery is provided below the throwing device. Among them, the delivery mechanism 202 can be a steel wire strand lowering delivery structure. For example, in the Chinese patent document "A UAV Mounted Automatic Throwing Device, Publication No. CN111038700A", a reduction motor drives the motor fixed shaft and the wire winding wheel to rotate, thereby realizing automatic throwing; the delivery mechanism '202' can also be a suspension point delivery structure. For example, in the Chinese patent document "A Throwing Device of a UAV, Publication No. CN215663990U", it throws at the suspension point and can automatically complete the throwing action according to the flight state of the UAV; these existing delivery structures can be directly applied in this application by welding or bolt connection to the bottom surface of the fuselage 201; as Figure 1 shown in the example of the power replenishment system, the external battery pack 4 is configured with two lugs and connected to the delivery mechanism 202; as Figure 16 shown in the example of the power replenishment system, the external battery pack '4' is configured with one lug and connected to the delivery mechanism 202; as Figure 17In the illustrated power replenishment system example, the external battery pack '4' is configured with a lifting lug connected to the delivery mechanism '202'. This application improves the outer shell of the external battery pack dropped by the existing UAV body and its connection structure to the object to be wired. The number of the external battery pack and the connection structure can be set according to the actual situation; the object to be wired is an operation UAV or an outdoor operation device. The conductive sheet II is electrically connected to the circuit of the operation UAV or the outdoor operation device through the wire II. In this way, the UAV body is controlled to slowly descend with the external battery pack, and it is controlled to align the socket seat with the fixed seat for socketing. After the socketing is completed, the delivery mechanism is controlled to throw the external battery pack to replenish power for the operation UAV or the outdoor operation device landing in the field operation. This application is described by taking an example of externally connecting an external battery pack to the operation UAV 100.

[0039] The external battery pack can be a storage battery pack, a lithium battery pack or a non-rechargeable battery pack, and its power parameters are adapted to the circuit of the object to be wired. For example, a 5V or 12V, 24V lithium battery pack, etc. are used. Even a step-down and current-stabilizing circuit is configured on the object to be wired for adaptation, and a hanging structure is arranged on its outer shell and assembled and thrown with the thrower. The lithium battery pack is also configured with a battery management system to monitor the battery and regulate the output power, which are all existing technologies. Since the battery pack has positive and negative wiring, there are two conductive sheets I22 to respectively connect the positive and negative poles through the wire I, and there are also two conductive sheets II12 to respectively connect the positive and negative poles through the wire II.

[0040] The wire I can be directly welded to the conductive sheet I, and the wire II can be directly welded to the conductive sheet II. Of course, for quick wiring, the power supply interconnection component further includes a terminal I and a terminal II. The I end of the terminal I is connected to the conductive sheet I, the II end of the terminal I is connected with the wire I, the I end of the terminal II is connected to the conductive sheet II, and the II end of the terminal II is connected with the wire II; correspondingly, the number of the terminal I23 and the terminal II13 is two; both the terminal I and the terminal II are existing terminal structures with plug-in or threaded connections, so that quick wiring can be realized. Or, the wire I is directly welded to the conductive sheet I, and the wire II is connected to the conductive sheet II through the terminal II.

[0041] The socket base 2 and the fixed base 1 adopt a socket structure with a plug interface. As shown in the figure, in this Embodiment 1, the socket base 2 is a plug structure, which is made of plastic or the like, and is in the shape of a sheet plate or a cylindrical structure. A conductive sheet (such as a copper sheet, for example, with a thickness of 1 mm and a width of 10 mm) I is bonded or bolted to its outer wall, and the terminal I can be welded or bolted to the conductive sheet I; the fixed base 1 is an interface structure, which is in the shape of a large end and a small end. Corresponding to the socket base, the inner cavity 11 of the fixed base 1 is in the shape of a right trapezoid, an isosceles trapezoid, a frustum of a pyramid or a frustum of a cone (funnel). The fixed base 2 is made of plastic or the like, and its inner side wall is bonded or bolted to the body shell. A conductive sheet (such as a copper sheet, for example, with a thickness of 1 mm and a width of 10 mm) II is bonded or bolted to the inner cavity wall surface. Among them, a flared opening for socket guiding is provided on the fixed base, which is designed to have a large end and a small end structure, forming an alignment error space, facilitating the unmanned aerial vehicle body to achieve alignment. As shown in the figure, this application takes a sheet plug (for example, with a length, width and height of 35 mm * 2 mm * 50 mm, and 10 mm copper sheets are arranged at intervals on both sides of the 35 mm board surface) and a right trapezoid-shaped interface (with a length and width of 40 mm * 40 mm at the large end, a length and width of 40 mm * 2 mm at the small end, and a depth of 50 mm) socketing as an example for illustration.

[0042] The fixed end of the socket base 2 is bonded or bolted and fixedly connected to the outer side wall of the housing of the external battery pack 4, and the fixed end of the fixed base is arranged on the outer side wall of the body shell 101 of the working unmanned aerial vehicle, and their ground clearances are basically the same. The working unmanned aerial vehicle takes a quadrotor unmanned aerial vehicle as an example. The four rotors are arranged at the four corners of the frame through its support arms. The fixed bases are arranged at the four sides of the frame. The fixed bases can be fixed on the side wall of the frame or on the side wall of the body below the frame, and the fixed bases protrude relative to the frame to expose the fixed bases to leave a relatively wide space for socketing.

[0043] During use, control the power supply replenishing unmanned aerial vehicle 200 to approach and land near the working unmanned aerial vehicle 100 on the ground 300. After reaching a certain height, the power supply replenishing unmanned aerial vehicle flies to a position where the socket base and the fixed base can be aligned and inserted. Then control the power supply replenishing unmanned aerial vehicle to vertically descend a certain height or tilt outward and descend a certain height, and the socketing of the socket base and the fixed base can be completed. Then control the throwing mechanism to throw the external battery pack, and the power supply of the working unmanned aerial vehicle landing in the wild can be realized. The external battery pack can be used as an operating power supply to supply power for the operation and standby maintenance of the working unmanned aerial vehicle, thereby reducing the consumption of the power supply of the working unmanned aerial vehicle itself. After the operation is completed, the working unmanned aerial vehicle takes off and returns. Pull up the socket base, the wire and the external battery pack. Since the socket base is relatively thin, it will be bent under the downward pulling force of the gravity of the external battery pack. After the socket base is bent, it will come out, and the plugging structure or the threaded connection structure between the terminal I and the wire I will be pulled out or loosened under the downward pulling force of the gravity of the external battery pack. In this way, the connection can be disconnected, and the external battery pack is left in place for abandonment, or waiting for the power supply replenishing unmanned aerial vehicle or manual recovery.

[0044] On the other hand, in the scenarios of outdoor working equipment such as landslide monitoring equipment, there are the following situations: First, due to the temporary application and operation of the equipment, the original battery carried may not be sufficient to support long-term work, and thus recharge is required; second, the equipment is permanent, and due to the damage of the recharge device such as solar energy but it is difficult to repair and replace it in time, or because the original battery is due for replacement but the maintenance personnel are busy and it is difficult to repair and replace it in time, it will cause insufficient power and thus need to be recharged. At this time, this application solution can be used to solve the problem. A fixed seat can be set on the outdoor working equipment in advance. When recharge is needed, the drone can be controlled to arrive at the scene quickly. After the socket is completed, recharge can be achieved. The original battery and the external battery pack are both used as the operating power source of the equipment to achieve operation and standby power supply. After the operation is completed or the external battery pack is used up, it can be recovered by the recharge drone.

[0045] As mentioned above, a delivery mechanism is configured on the drone body to install an external battery pack and enable it to be thrown under the control of the drone body. A socket is provided on the outer wall of the external battery pack, and a fixed seat is provided on the wired object. The socket or the fixed seat is provided with an expansion for socketing guidance to form an alignment error space. The drone body flies to the socket and the fixed seat to align with the socket position, and then falls to complete the socketing of the socket and the fixed seat. After the socketing is completed, the delivery mechanism is controlled to throw the external battery pack to realize the charging of the operating drone or outdoor operating equipment landing in the field, as the operating and standby maintenance power supply. It can be powered in parallel; it can also realize power monitoring and regulation through the battery management system configured in the lithium battery pack to reduce the output power of the power battery, and give priority to the use of external battery packs for power supply, which are all existing technologies.

[0046] Example 2

[0047] The difference between the second embodiment and the first embodiment lies in the connection structure between the socket and the external battery pack. For other details not fully described, please refer to the first embodiment.

[0048] For example, the socket in Example 1 is fixed on the external battery pack and needs to be connected and thrown at a close distance. The external battery pack has a certain height below to support it after connection. The volume of the external battery pack may affect the alignment connection. The shaking when throwing may affect the operation of the drone or outdoor business equipment. Therefore, see Figures 1 - 9 In this embodiment 2, the socket adopts a detachable connection structure, and the wire I has a certain length, such as 20 mm or 50 mm.

[0049] Among them, an existing robotic arm can be used. The battery replenishing drone is configured with a robotic arm. The socket seat is connected to the external battery pack through a wire. The robotic arm gripper grabs the socket seat and, during socketing, cooperates with the movement of the robotic arm to make the alignment and socketing actions more precise. After socketing, the socket seat is released, and then the battery pack is thrown. Considering cost, an existing telescopic arm and the electromagnetic clamp thereon can be used to replace the robotic arm. The telescopic arm is arranged on the battery replenishing drone, and the electromagnetic clamp adsorbs the socket seat. During socketing, it cooperates with the downward movement of the telescopic arm for relatively accurate socketing. After that, the electromagnetic clamp is released, and the battery pack is thrown. To reduce weight and further control costs, a suspension structure, or a suspension structure with elastic clamping or elastic limitation is adopted; for example, a sliding connection using a slide rail is adopted; for example, a clamping connection using a clip is adopted. The clip is connected to the external battery pack through a support rod. The clip clamps the socket seat, and the socket seat slips out of the clip after receiving a certain force. The following will elaborate on the sliding connection using a slide rail. The clamping connection using a clip can be realized by referring to the slide rail sliding connection with elastic limitation, and other connection structures can be realized by referring to the existing technology.

[0050] See Figures 1 - 9 , in order to increase the throwing range of the external battery and reduce the impact on the object to be wired during the throwing process, the external battery replenishing system of the drone further includes a sliding bolt member. The sliding bolt member includes a slide rail 3 and a slider 21. The lower end of the slide rail 3 is arranged on the outer side wall of the external battery pack. A track 31 is arranged on the slide rail 3. The socket seat 2 includes a socket seat body 20 and a slider 21. The fixed end of the socket seat body 20 is provided with a slider 21, and the slider 21 is slidably connected to the track 31 in a matching manner. An assembly port is arranged at the upper end of the track 31, and the slider can slide into or out of the assembly port under the action of an external force.

[0051] The track 31 is arranged to be inclined outward from bottom to top. It can be welded or bolted to the outer shell of the external battery pack through a bracket 32 so as to leave a wider space for aligning and socketing the socket seat. After alignment, it falls downward or outward. The socket seat is sleeved on the fixed seat, and then continues to fall. The fixed end of the socket seat is subjected to the upward pushing action of the connecting end of the fixed seat, and then continues to fall. The connecting end of the fixed seat will push the socket seat out of the track to achieve socketing. The track is illustrated by a cavity channel. Corresponding to the cavity channel, the slider adopts a rectangular body, a cylindrical body, an elliptical cylindrical body structure, etc. As shown in the figure, a cylindrical structure is adopted. Moreover, compared with the circumferential limit of the rectangular body, the cylindrical body or the elliptical cylindrical body can rotate circumferentially. In this way, the socket seat body can vertically droop under the action of gravity, which is more conducive to alignment and socketing. Of course, the track can also adopt a slide bar structure. At this time, the slider is correspondingly provided with a slideway so that the slider is slidably connected to the slide bar. It can be realized by referring to the aforementioned cavity channel and the existing technology, and will not be elaborated here.

[0052] In this way, a detachable connection between the socket seat and the external battery pack is realized. Then, through an external connection with a wire I of a certain length, the external battery pack can move within a large range to find a more suitable position for throwing, and it will not touch the operating drone or outdoor business equipment during throwing and shaking.

[0053] Based on the foregoing examples, in a preferred example, in order to limit the socket to prevent it from easily slipping out of the slide rail, the sliding bolt member further includes an elastic protruding member. The elastic protruding member is disposed at the assembly port of the rail. In the initial natural state, the elastic protruding member protrudes into the rail to block the slider, and the elastic protruding member is compressed to vacate the rail when the slider is extruded by a certain external force, that is, the socket slides out of the rail to achieve disengagement of the socket when the upward acting force value of the fixed seat connection end exceeds the acting force of the elastic protruding member. As shown in the figure, taking the arrangement of two elastic pieces 33 at the assembly port of the rail 31 in the cavity channel as an example, other examples such as the elastic protruding member of the umbrella rod will not be elaborated one by one. In this way, the elastic protruding member can limit the slider, and can slide into or out of the assembly port after the slider is extruded by an acting force above a certain external force value.

[0054] Embodiment 3

[0055] This Embodiment 3 is an improved solution of Embodiment 1 or 2. For other unmentioned descriptions, please refer to the foregoing Embodiments 1-2.

[0056] See Figures 1 - 9 , in this Embodiment 3, in order to improve the stability of the contact connection between the conductive sheet I and the conductive sheet II, in the external power supply replenishment system of the drone, the power supply interconnection component further includes a locking member. The locking member is disposed on the fixed seat or the object to be wired, and can press the socket tightly against the fixed seat when the socket is sleeved on the fixed seat.

[0057] Among them, referring to the elastic protruding member in the foregoing Embodiment 2, a groove can be provided on the socket and an elastic protrusion (a protruding ball and a spring connected to its bottom) or an elastic piece can be provided in the fixed seat. When pressed down to the position corresponding to the groove of the protrusion, the protruding ball protrudes into the groove due to the restoring action of the spring (or the elastic piece returns to its natural state due to its elasticity), thereby locking. As Figure 15 shown in the example of the power supply replenishment system, a groove is provided on the socket, and an arc-shaped elastic piece 14 and a shrinkage hole are provided in the fixed seat to achieve assembly and locking.

[0058] In this way, after the socketing is in place, the locking member locks, so that the conductive sheet I and the conductive sheet II are in close contact connection.

[0059] Different from the foregoing examples, in a preferred example, the locking member is an electric control lock 5. The fixed end of the fixed seat 1 is disposed on the outer wall of the housing of the object to be wired (such as the housing 101 of the operating drone shown in the figure). The electric control lock 5 is disposed inside the housing of the object to be wired, and the lock tongue of the electric control lock can penetrate a certain length out of the housing of the object to be wired to press the sleeve seat against the fixed seat. For example, corresponding to the foregoing example, the length of the lock tongue in the telescopic direction changes from 40 mm to 2 mm, and the lock tongue is at the lower middle position and can penetrate 20 - 30 mm, so that it can be pressed against the sleeve seat. Among them, the electric control lock can be connected by welding or bolts. As shown in the figure, installation holes 51 and 52 are provided for bolt connection and fixation, and a locking hole 53 is provided for passing the lock tongue. When the electric control lock is locked, the lock tongue penetrates out of the inner side wall of the fixed seat and approaches the outer side wall of the fixed seat, so as to press tightly on the sleeve seat therebetween. The electric control lock and its connection control with the main controller of the supplementary power drone are all existing technologies and will not be elaborated here. Of course, referring to the principle of the electric control lock, a micro motor can also be used to control the telescopic movement of the bolt through gear transmission to achieve locking. In this way, after the socketing, the electric control lock is controlled to be locked, and the lock tongue of the electric control lock extends out and locks, so that the conductive sheet I and the conductive sheet II are in close contact connection. Compared with the mechanical locking structure of the elastic convex component in the foregoing example, using the electric control lock is more labor-saving when pulling out the sleeve seat.

And when the socket is sleeved on the fixed seat, the conductive sheet I is in contact connection with the conductive sheet II. A misalignment error space is formed by arranging the flared opening for socketing guidance on the socket or the fixed seat, so as to be applied to drones or other similar application scenarios that require guiding and aligning for sleeving. The drone body flies to the position where the socket and the fixed seat can be aligned and sleeved, and then it can complete the sleeving of the socket and the fixed seat by falling.

[0069] Based on the foregoing solution, in an improved solution, the power supply interconnection component further includes a locking member. The locking member is arranged on the fixed seat or the object to be wired, and it can press the socket tightly against the fixed seat when the socket is sleeved on the fixed seat. In a preferred example, the locking member is an electric control lock. The fixed end of the fixed seat can be arranged on the outer side wall of the housing of the object to be wired. The electric control lock can be arranged inside the housing of the object to be wired, and the lock tongue of the electric control lock can penetrate a certain length out of the housing of the object to be wired to press the socket tightly against the fixed seat.
