[0047] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art based on the present application belong to the scope of protection of the present application.

[0048] As Figure 1a 、Figure 1b , Figure 2 As shown in Figure 2 , a drone charging device is provided in the first aspect of the present application. The drone charging device includes a platform module 1, a position adjustment mechanism, a charging module 4, and a control unit. The platform module 1 includes a fixed platform 11 for a drone 5 to dock. The position adjustment mechanism is located below the fixed platform 11. The charging module 4 is provided on the position adjustment mechanism. The charging module 4 includes at least two types of charging units 41. The control unit (not shown in the figure) is configured to control the position adjustment mechanism to drive one of the charging units 41 to a specified position so that the charging unit 41 can be docked with the charging docking unit 54 of the drone 5. That is, the control unit can determine the charging unit 41 that matches the drone 5 to be charged from multiple types of charging units 41, and control the position adjustment mechanism to drive the determined charging unit 41 (i.e., the position adjustment mechanism drives one of the charging units 41) to a specified position so that the determined charging unit 41 can be docked with the charging docking unit 54 of the drone 5.

[0049] In the embodiment of the present application, the drone charging device has at least two different types of charging units 41, so it can match drones 5 of different models. The position adjustment mechanism can drive the determined charging unit to a specified position so that the determined charging unit can be docked with the charging docking unit of the drone, realizing automatic docking and charging. Therefore, the drone charging device can adapt to the charging docking units 54 at different positions and different heights of the drone 5. Through the sharing of the drone charging device, the compatibility and convenience of the drone charging device are improved.

[0050] Specifically, the "type" in the above embodiment includes both the model of the charging unit 41 and the installation direction of the interface of the charging unit 41. That is to say, multiple types of charging units 41 can be any of the following situations:

[0051] Multiple types of charging units 41 refer to charging units with the same model but different installation directions of the interfaces. For example, for charging units of the same model, some interfaces face upward, such as the electrode terminals 411 being vertically upward, while some other interfaces face the side, such as the electrode terminals 411 being horizontally oriented.

[0052] Multiple types of charging units 41 can also refer to charging units 41 with different models but the same installation direction of the interfaces. For example, for charging units of different models, all interfaces face the side, such as the electrode terminals 411 being horizontally oriented.

[0053] The multiple types of charging units 41 can also refer to the models of the charging units 41 and the installation directions of the interfaces are different. For example, there are charging units of the same model at the same time. Some interfaces face upward, such as the electrode terminals 411 are arranged vertically upward, while some other interfaces face sideways, such as the electrode terminals 411 are arranged horizontally. At the same time, there are also charging units of different models. The interface orientations of these different models of charging units can be the same or different. For example, for different models of interfaces, some interfaces face upward, such as the electrode terminals 411 are arranged vertically upward, while some other electrode terminals 411 are arranged horizontally.

[0054] Among them, the charging module 4 can be a wired charging module, a wireless charging module, or the charging module 4 includes both a wired charging module and a wireless charging module. Whether it is a wired charging module or a wireless charging module, it can include different types of charging units 41. When the charging module 4 is a wired charging module, the inner terminals in the interfaces of the charging units 41 in the wired charging module need to be in contact with the corresponding terminals in the charging docking unit 54 in the drone. For example, the two need to be plugged in to achieve electrical connection and then charge. When the charging module 4 is a wireless charging module, the charging units 41 in the wireless charging module only need to be within a preset range from the charging docking unit 54 set on the drone to dock and charge, without the need for interface plugging.

[0055] In addition, the number of each same type of charging unit 41 can be one, two, or even more. The present application does not limit this. Exemplarily, when the number of the same type of charging unit 41 is one, it can charge the matching drone 5 through a single port. When the number of the same type of charging unit 41 is two, it can charge the matching drone 5 through two ports, improving the charging efficiency.

[0056] In addition, the drone charging device can automatically match a suitable charging unit 41 according to the model of the drone 5 and the type of the charging docking unit, and automatically adjust the required charging unit 41 to the charging position through the position adjustment mechanism to dock and charge with the charging docking unit of the drone 5. The whole process can be automatically operated in a unmanned environment, reducing the labor input and improving the charging efficiency of the drone 5.

[0057] In some embodiments of the present application, such as Figure 3 , Figure 4 As shown, at least one charging hole 111 is provided on the fixed platform 11. The platform module 1 includes at least one protective cover 12 and at least one protective cover driving device. Each protective cover 12 corresponds to one charging hole 111, and each protective cover 12 blocks or opens the corresponding charging hole 111 under the drive of the protective cover driving device.

[0058] In the embodiments of the present application, the fixed platform 11 can be used for the landing of the leg-type drone 5. Such asFigure 5 , Figure 6 , Figure 7 and Figure 8 As shown in Figure 5 , Figure 6 , Figure 7 and Figure 8 , the charging docking unit 54 of the landing-leg type UAV 5 is provided on one or two of the landing legs 51. When charging is required, the protective cover driving device drives the protective cover 12 to move away, exposing the charging hole 111. The charging docking unit 54 on the landing leg 51 is docked with the charging unit 41 through the charging hole 111 for charging. The structure is simple and easy to operate. When charging is not required, the protective cover driving device drives the protective cover 12 to block the charging hole 111, which can improve the sealing performance of the UAV charging device.

[0059] Specifically, as Figure 4 shown, there are two charging holes 111. The protective cover 12 is arranged in one-to-one correspondence with the charging holes 111, and each protective cover 12 corresponds to a protective cover driving device. The protective cover 12 can be automatically opened or blocked under the drive of the protective cover driving device. The protective cover driving device includes a first sliding track 134 and a second sliding track 135 provided on the back of the fixed platform 11, a power component for driving the movement of the protective cover 12, and a first sliding member 121 and a second sliding member 122 that cooperate with the first sliding track 134. The first sliding member 121 and the second sliding member 122 are arranged at the head and tail ends of the protective cover 12. The first sliding track 134 corresponds to the position of the charging hole 111. The second sliding track 135 is arranged adjacent to the first sliding track 134 and is arranged in sequence along the sliding direction of the protective cover 12. The first sliding track 134 and the second sliding track 135 extend from the side of the fixed platform 11 to the bottom of the fixed platform 11. The power component can be a servo motor or the like. The power component drives the protective cover 12 to reciprocate along the sliding track, thereby opening or blocking the charging hole 111. One power component can drive one protective cover 12 or multiple protective covers 12.

[0060] Of course, the protective cover driving device can also be a combination of a link mechanism and a power component, that is, the power component drives the protective cover 12 to open or block the charging hole 111 through the link mechanism; or the protective cover driving device is a combination of a rotating shaft and a power component. The power component drives the rotating shaft to rotate, so that the protective cover 12 flips to open or block the charging hole 111.

[0061] The sliding component that drives the movement of the protective cover (for example, the sliding component includes a driving part and a sliding track) usually has a one-to-one relationship with the protective cover to ensure that each protective cover can be individually controlled. In different embodiments, multiple protective covers can also be controlled by one sliding component, that is, one sliding component corresponds to multiple protective covers, so that the movement of multiple protective covers can be controlled simultaneously. The power component in the protective cover driving device can be one or more. Each power component can correspond to one sliding component to control one protective cover, or one power component can simultaneously control multiple sliding components, and then control each protective cover. When one power component controls multiple protective covers, these multiple protective covers can move synchronously or separately.

[0062] In some embodiments of the present application, such as Figure 3 , Figure 4 As shown, the fixed platform 11 is provided with a stop through hole 112; the platform module 1 further includes a lifting platform 13 for controlling the docking height of the drone 5. The lifting platform 13 includes a platform plate 131 and a first lifting component 132. The platform plate 131 is arranged at a position corresponding to the stop through hole 112 and is connected to the first lifting component 132. The platform plate 131 moves up and down under the drive of the first lifting component, so that the platform plate 131 passes through the through hole 112 and is located above or below the fixed platform 11.

[0063] In the embodiments of the present application, the lifting platform 13 can be used for the docking of the arm-landing type drone 5. The platform plate 131 of the lifting platform 13 can be lifted and lowered under the action of the first lifting component 132 and lowered below the fixed platform 11, so that the fuselage 53 of the drone is located in the stop through hole 112, and the arms 52 are docked on the fixed platform 11, which can play a role in fixing the drone 5 to ensure stability during the charging process.

[0064] Such as Figure 9 and Figure 10 As shown, the charging docking unit 54 of the arm-landing type drone 5 is arranged on the fuselage 53. The charging docking unit 54 can be provided with one or two. The two charging docking units 54 are respectively located on both sides of the fuselage 53 and are opposite in position, such as Figure 9As shown in the figure. When the arm-dropping UAV 5 lands on the lifting platform 13, the fuselage 53 is supported on the lifting platform 13 and sinks as the lifting platform 13 sinks. When the arm 52 is supported on the fixed platform 11, the sinking stops, so that the charging docking unit 54 on the fuselage 53 is located below the through hole 112. The charging unit 41 can be docked with the charging docking unit 54 under the adjustment of the position adjustment mechanism for charging. It can be seen that the platform module 1 in this embodiment can be used to charge both the leg-dropping UAV 5 and the arm-dropping UAV 5. And under the adjustment of the position adjustment mechanism, the position of the charging docking unit 54 can be flexibly arranged, further improving the compatibility of the UAV charging device.

[0065] Optionally, as Figure 4 shown, the first lifting component 132 includes a first slide rail 1321, a first slider 1322 and a first driving member (not shown in the figure). The first slider 1322 is arranged on the first slide rail 1321, and the first driving member is used to drive the first slider 1322 to slide up and down along the first slide rail 1321. Among them, the first driving member can be a lead screw motor or a linear motor. The platform plate 131 and the first slider 1322 can be connected through a mounting bracket 133, so that when the first slider 1322 moves up and down, it can drive the platform plate 131 to move up and down. Specifically, the mounting bracket 133 is an inverted "L" type mounting plate. The inverted "L" type mounting plate includes a horizontal plate at the top and a vertical plate connected to the horizontal plate. The horizontal plate is fixedly connected to the platform plate 131, and the vertical plate is connected to the first slider 1322.

[0066] The platform plate 131 is connected to the first slider 1322 through the mounting bracket 133. Under the drive of the first driving member, the platform plate 131 can move up and down along the first slide rail 1321. When the platform plate 131 moves downward, it can be located below the fixed platform 11. When the platform plate 131 moves upward, it can be reset to be flush with the fixed platform 11.

[0067] It can be understood that when the fixed platform 11 is used for the UAV 5 to dock, the lifting platform 13 can be raised to be flush with the fixed platform 11, so that the through hole 112 on the fixed platform 11 can be filled by the lifting platform 13, facilitating the docking of the UAV 5. According to the different models of the UAV 5, the lifting platform 13 can be higher or lower than the fixed platform 11.

[0068] In some embodiments of the present application, such as Figure 11 、 Figure 12 、 Figure 13 and Figure 14As shown, the position adjustment mechanism includes a horizontal adjustment mechanism 2, and / or a lifting mechanism 3, and / or a rotating mechanism 6. The horizontal adjustment mechanism 2 is disposed below the fixed platform 11 through a mounting bracket. The horizontal adjustment mechanism 2 can control the charging module 4 disposed thereon to reciprocate in the horizontal direction. The lifting mechanism 3 is disposed below the fixed platform 11 through a mounting bracket 7. The lifting mechanism 3 is used to control the charging module 4 disposed thereon to reciprocate in a direction perpendicular to the ground. The rotating mechanism 6 is disposed below the fixed platform 11 through a mounting bracket 7. The rotating mechanism 6 is used to control the charging module 4 disposed thereon to rotate along the rotation axis of the rotating mechanism 6, wherein the rotation axis is parallel to the horizontal direction or perpendicular to the horizontal direction.

[0069] In the embodiment of the present application, the position adjustment mechanism may only include the horizontal adjustment mechanism 2, or may only include the lifting mechanism 3, or may only include the rotating mechanism 6, or the position adjustment mechanism may include two of them. Of course, the position adjustment mechanism may also include the horizontal adjustment mechanism 2, the lifting mechanism 3, and the rotating mechanism 6.

[0070] When the position adjustment mechanism includes two of them, for example, the position adjustment mechanism includes the horizontal adjustment mechanism 2 and the lifting mechanism 3, so that the installation position of the charging unit 41 is more flexible. When the position adjustment mechanism includes the horizontal adjustment mechanism 2 and the lifting mechanism 3, the lifting mechanism 3 may be disposed on the horizontal adjustment mechanism 2, that is, first translate and then lift, or the horizontal adjustment mechanism 2 may be disposed on the lifting mechanism 3, that is, first lift and then translate. For another example, when the position adjustment mechanism includes the horizontal adjustment mechanism 2 and the rotating mechanism 6, the rotating mechanism 6 may be disposed on the horizontal adjustment mechanism 2, and can first translate and then rotate. For another example, when the position adjustment mechanism includes the lifting mechanism 3 and the rotating mechanism 6, the rotating mechanism 6 may be disposed on the lifting mechanism 3, and can first lift and then rotate.

[0071] When there is only one of the horizontal adjustment mechanism 2, the lifting mechanism 3, or the rotating mechanism 6, it can be respectively installed below the fixed platform 11 through the mounting bracket 7. The mounting bracket 7 may be as Figure 1a shown, including a side plate 71 and a bottom plate 72. The side plate 71 is connected to the bottom plate 72. The side plate 71 is disposed around the outer periphery of the fixed platform 11. The fixed platform 11 is connected to the side plate 71. The position adjustment mechanism can be placed on the bottom plate 72 through a support assembly. Figure 1a The mounting bracket 7 in Figure 1aThe mounting bracket 7 therein can also maintain the sealing of the drone charging device, thereby protecting the internal structure of the drone charging device and playing roles such as dustproof and waterproof. Of course, the mounting bracket 7 can also be other structures, such as a frame structure, which is used to respectively support and fix the platform module 1 and the position adjustment mechanism, so that the position adjustment mechanism is located below the fixed platform 11, and the lifting platform 13 can lift relative to the fixed platform 11. As shown in Figure 1a The mounting bracket 7 shown in

[0072] is only a possible mounting bracket, and the embodiments of the present application do not limit the specific structure of the mounting bracket 7. Any bracket that can be used to mount the drone charging device can be used in the present application. Figure 1a It can be understood that when the drone charging device adopts the mounting bracket 7 shown in

[0073] the control unit can be arranged on the bottom plate 72 or the side plate 71 of the mounting bracket 7, and the present application does not limit this. When the platform module 1 and the position adjustment mechanism of the drone charging device are fixed by other frame structures, the control unit can be arranged on the frame structure.

[0074] The horizontal adjustment mechanism 2 can be a one-dimensional translation mechanism or a two-dimensional translation mechanism, so as to facilitate different charging units 41 of the charging module 4 to be docked with the charging docking unit 54 to realize the charging function of the drone 5.

[0075] The lifting mechanism 3 can adjust the position of the charging unit 41 in the vertical direction, so that the charging unit 41 can be docked with the charging docking unit 54 to realize the charging function of the drone 5. In order to realize the versatility of the drone charging device, when only the lifting mechanism 3 is included, multiple charging units 41 are arranged on the lifting mechanism 3. For example, multiple charging units 41 can be controlled by an ejection control component, and only the matching charging unit 41 can be ejected and docked with the charging docking unit 54 through lifting for charging.

[0076] In some embodiments of the present application, as shown in Figure 11 、 Figure 12 、 Figure 13 and Figure 14As shown in the figure, the horizontal adjustment mechanism 2 includes two first translation components 21, a second translation component 22, and at least one first horizontal link 23 that are oppositely arranged along a first horizontal direction; a charging module 4 is provided on the first horizontal link 23. The first end of the first horizontal link 23 is connected to the first translation component 21, and the second end is connected to the second translation component 22. Driven by the first translation component 21 and the second translation component 22, the first horizontal link 23 reciprocates along a second horizontal direction.

[0077] In this embodiment, there are two charging holes 111, and there are also two first horizontal links 23. Of course, more than two first horizontal links 23 can be provided. The first horizontal link 23 slides along the second horizontal direction Y on the first translation component 21 and the second translation component 22. The charging module 4 is arranged on the first horizontal link 23 and, driven by the first horizontal link 23, reciprocates along the second horizontal direction Y, thereby moving the charging module 4 to a specified position. It can be understood that in order to realize the versatility of the UAV charging device in this embodiment, a plurality of charging units 41 are provided on the first horizontal link 23, and a plurality of charging holes 111 are provided on the fixed platform 11. Through one translation, different charging units 41 can reach the positions of their respective matching charging holes 111 and dock with the charging docking unit 54. Since the first horizontal link 23 can drive the charging unit 41 to reciprocate in the second horizontal direction Y, a horizontal movement in one-dimensional direction is actually realized.

[0078] Optionally, as Figure 11 、 Figure 12 、 Figure 13 and Figure 14 shown, the first translation component 21 includes a fourth driving member 211, a second slide rail 212, and a second slider 213. The second translation component 22 includes a fifth driving member 221, a third slide rail 222, and a third slider. The first end of the first horizontal link 23 is connected to the second slider, and the second slider is arranged on the second slide rail 212. The second end of the first horizontal link 23 is connected to the third slider. The fourth driving member 211 and the fifth driving member 221 move synchronously and respectively drive the first end and the second end to reciprocate along the second horizontal direction Y.

[0079] The second translation component 22 can also only include the third slide rail 222 and the third slider 223 and share a driving component with the first translation component 21.

[0080] In this embodiment, the structures of the first translation component 21 and the second translation component 22 can be the same, which is beneficial to simplifying the structure of the horizontal adjustment mechanism 2. The fourth driving member 211 and the fifth driving member 221 move synchronously, so that the two ends of the first horizontal link 23 move in unison, thereby ensuring the linear movement of the first horizontal link 23.

[0081] Among them, the fourth driving member 211 and the fifth driving member 221 can be a lead screw motor, a linear motor, or the like.

[0082] Taking the fourth driving member 211 and the fifth driving member 221 as lead screw motors as an example, as Figure 11 、 Figure 12 、 Figure 13 and Figure 14 shown, the fourth driving member 211 is a first lead screw motor. The first lead screw motor includes a first motor 211a, a first lead screw 211b connected to the first motor 211a, and a first nut (not shown in the figure) sleeved on the first lead screw 211b. The second slide rail 212 is arranged in parallel with the first lead screw 211b, and both ends of the second slide rail 212 and both ends of the first lead screw 211b are fixed by a first support seat 214. The fifth driving member 221 is a second lead screw motor. The second lead screw motor includes a second motor 221a, a second lead screw 221b connected to the second motor 221a, and a second nut (not shown in the figure) sleeved on the second lead screw 221b. The third slide rail 222 is arranged in parallel with the second lead screw 221b, and both ends of the third slide rail 222 and both ends of the second lead screw 221b are fixed by a second support seat 224. The first end of the first horizontal connecting rod 23 is connected to the first nut through a second slider 213, and the second end of the first horizontal connecting rod 23 is connected to the second nut through a third slider 223. The first nut and the second nut are left-handed nuts or right-handed nuts.

[0083] In combination with the present application, the first end of the first horizontal connecting rod 23 is connected to the first nut through a second slider 213, and the second end of the first horizontal connecting rod 23 is connected to the second nut through a third slider 223. The first nut and the second nut are left-handed nuts or right-handed nuts. Both ends of the first horizontal connecting rod 23 are connected to nuts of the same type through the second slider 213 and the third slider 223 respectively. When the lead screw rotates, both ends of the first horizontal connecting rod 23 can move synchronously, so that the first horizontal connecting rod 23 moves along the linear guide rail 241.

[0084] In some embodiments of the present application, as Figure 11 、 Figure 12 shown, the horizontal adjustment mechanism 2 further includes a third translation assembly 24, which is arranged between the first horizontal connecting rod 23 and the charging module 4 and drives the charging module 4 to reciprocate in the first horizontal direction X.

[0085] In this embodiment, the charging module 4 is not directly disposed on the first horizontal link 23, but is connected to the third translation assembly 24. The third translation assembly 24 is connected to the first horizontal link 23, and the third translation assembly 24 drives the charging module 4 to move in the first horizontal direction X. This is equivalent to the charging module 4 being able to move arbitrarily in the first horizontal direction X and the second horizontal direction Y. That is, by providing the third translation assembly 24, two-dimensional movement of the charging module 4 can be achieved, thereby more conveniently adjusting the position of the charging module 4 so that one of the charging units 41 is located at a specified position and docks with the charging docking unit 54 to charge the drone 5.

[0086] Optionally, as Figure 11 , Figure 12 shown, the third translation assembly 24 includes a linear guide rail 241, at least two sliding blocks (not shown in the figure), a transmission mechanism 243, and at least two second driving members 242. The linear guide rail 241 is fixedly connected to the first horizontal link 23. At least two sliding blocks are provided on the linear guide rail 241. The transmission mechanism 243 includes a first member 2431 and at least two second members 2432 that mesh with each other. Each second member 2432 corresponds to a second driving member 242. The charging unit 41 is fixed to the sliding block and is connected to the second driving member 242 through the mounting seat 33. Driven by the second driving member 242, the second driving member itself together with the charging unit 41 can move along the linear guide rail 241 so that the charging unit 41 is located at a specified position. Among them, the second driving member 242 can be a servo motor.

[0087] As Figure 11 , Figure 12 shown, the sliding block is correspondingly arranged with the second member 2432, and the second member 2432 is correspondingly arranged with the charging unit 41.

[0088] Exemplarily, the first member 2431 can be a rack or a chain, and the second member 2432 can be a gear. At least two gears are meshed on the rack.

[0089] As Figure 12 shown, taking the first member 2431 of the transmission mechanism 243 as a rack and the second member 2432 as a gear as an example, the teeth of the rack are arranged downward, and the top of the rack is fixedly connected to the linear guide rail 241, for example, it can be fixedly connected by screwing. The gear can be fixed to the second driving member 242 through the gear mounting seat. Through the engagement of the gear and the rack, the rack is fixedly connected to the linear guide rail, and the rotation of the gear will be converted into linear motion along the rack. Therefore, the second driving member 242 and the lifting mechanism 3 can move horizontally on the linear guide rail 241. It can be understood that if the rack is replaced with a chain, the structure is similar and the function remains unchanged, and the present application will not be elaborated herein.

[0090] In some embodiments of the present application, the lifting mechanism 3 includes a second lifting component 31 and a lifting installation component 32; the second lifting component 31 is arranged on the first horizontal connecting rod 23 through the lifting installation component 32, and the charging module 4 is connected to the second lifting component 31 through the lifting installation component 32, and reciprocates in the vertical direction under the drive of the second lifting component 31.

[0091] In this embodiment, the position adjustment mechanism may include a lifting mechanism 3 and a horizontal adjustment mechanism 2, and the lifting mechanism 3 is arranged on the horizontal adjustment mechanism 2, that is, the second lifting assembly 31 is installed on the first horizontal connecting rod 23 through the lifting installation assembly 32. The position adjustment mechanism may also only include the lifting mechanism 3, and the second lifting assembly 31 is connected to the mounting frame through the lifting installation assembly 32 and fixed under the fixed platform 11. For example, the lifting installation assembly 32 may be a U-shaped structure, the opening of the U-shaped structure is arranged horizontally, one end of the U-shaped structure is fixed to one side of the top end of the second lifting assembly 31, and is fixedly connected to the charging unit 41, and the other end of the U-shaped structure is fixed to one side of the bottom end of the second lifting assembly 31, and is fixedly connected to the mounting frame 7, so that the second lifting assembly 31 is fixed on the mounting frame.

[0092] Among them, the second lifting component 31 can be an electric lifting rod, a driving cylinder, a screw motor, etc. Taking the electric telescopic rod as an example, the electric telescopic rod includes components such as a motor, a transmission device, a telescopic rod, and a controller. The telescopic and adjustment functions of the electric telescopic rod are mainly realized by the motor drive. When the motor starts, it drives the transmission device to move, and the transmission device pulls the telescopic rod to achieve telescopic movement. The controller is mainly used to control the start and stop of the motor and the locking of the telescopic rod. Of course, in order to ensure the smooth operation of the telescopic rod, a guide device can also be included, and the guide device can be a common matching structure of a slide rail and a slider.

[0093] When the position adjustment mechanism includes a lifting mechanism 3 and a horizontal adjustment mechanism 2, illustratively, as Figure 7 As shown, the charging process of horizontal docking is explained by taking the leg-landing UAV 5 as an example. The leg-landing UAV 5 lands on the fixed platform 11, and the charging docking unit 54 of the UAV 5 is located above the charging hole 111. Therefore, the horizontal adjustment mechanism 2 must first adjust the charging unit 41 to be directly below the charging hole 111, and the charging unit 41 is located obliquely below the charging docking unit 54. The vertical projection of the two is that the charging unit 41 is located on the opposite side of the charging docking unit 54, and then the lifting mechanism 3 raises the charging unit 41 to a position flush with the charging docking unit 54. Finally, the charging unit 41 is adjusted by the horizontal adjustment mechanism 2 to be close to the charging docking unit 54 and docked with the charging docking unit 54 before the UAV 5 can be charged.

[0094] In some embodiments of the present application, the rotation mechanism 6 includes a rotation assembly 61 and a rotation mounting assembly 62; the rotation assembly 61 is arranged on the first horizontal connecting rod 23 through the rotation mounting assembly 62, and the charging module 4 is connected to the rotation assembly 61 through the rotation mounting assembly 62 and rotates around the rotation axis in the rotation assembly 61 under the drive of the rotation assembly 61, wherein the rotation axis is parallel or perpendicular to the horizontal direction.

[0095] Among them, the position adjustment mechanism may include both the rotation mechanism 6 and the horizontal adjustment mechanism 2, or may only include the rotation mechanism 6. When the position adjustment mechanism includes the rotation mechanism 6 and the horizontal adjustment mechanism 2, the rotation mechanism 6 is arranged on the horizontal adjustment mechanism 2, and the rotation assembly 61 is connected to the first horizontal connecting rod 23 through the rotation mounting assembly 62. For example, the rotation mounting assembly 62 includes a mounting block 621, the bottom end of the mounting block 621 is connected to the first horizontal connecting rod 23, and the top end is connected to the rotation assembly 61. At least one charging unit is provided on the rotation assembly 61.

[0096] The horizontal adjustment mechanism 2 may be a one-dimensional translation mechanism. Driven by the first horizontal connecting rod 23, the rotation mechanism 6 can move along the second horizontal direction Y to reach below the specified charging position, such as below the position of the charging hole 111, and driven by the rotation assembly 61, the charging unit arranged on the rotation assembly 61 rotates to below the charging position.

[0097] Optionally, the rotation assembly 61 includes a rotating table 611, a third driving member 612 and a rotary bearing 613, and a charging unit is provided on the rotating table 611. The third driving member 612 is arranged at the top end of the mounting block 621, the output shaft of the third driving member 612 is fixedly connected to the rotary bearing, and the rotary bearing is fixedly connected to the rotating table 611. When the third driving member 612 rotates, it can drive the rotary bearing to rotate and drive the rotating table 611 to rotate. Among them, the third driving member 612 can drive the rotary bearing 613 to rotate clockwise or counterclockwise. Among them, the rotary bearing 613 is the rotation axis of the rotation assembly.

[0098] When there is one rotation mechanism 6, at least two charging units 41 are provided on each rotating table 611. When there are two or more rotation mechanisms 6, at least one charging unit 41 is provided on each rotating table 611.

[0099] In the embodiment of the present application, a rotating table 611 is provided on the first horizontal connecting rod 23, and a plurality of charging units 41 are provided on the rotating table 611, and each charging unit 41 corresponds to a lifting mechanism 3.

[0100] In some embodiments of the present application, when the position adjustment mechanism includes a horizontal adjustment mechanism 2, a lifting mechanism 3, and a rotating mechanism 6, the lifting mechanism 3 is disposed on the horizontal adjustment mechanism 2, the rotating mechanism 6 is disposed on the lifting mechanism 3, and the charging module 4 is disposed on the rotating mechanism 6.

[0101] In this embodiment, the position adjustment mechanism simultaneously includes a horizontal adjustment mechanism 2, a lifting mechanism 3, and a rotating mechanism 6. The charging module 4 can first move horizontally on the position adjustment mechanism, then move up and down, and finally rotate, so that the charging module 4 moves to a specified position and docks with the charging docking unit 54 for charging.

[0102] In some embodiments of the present application, the size of the charging hole 111, such as the width and length, needs to match the size of the charging unit 41. However, in order to meet the charging requirements, the charging hole 111 can have a certain operating space in the length direction or the width direction, so that the charging unit 41 can be inserted into the charging docking unit 54. Leaving an operating space only in one direction can reduce the size of the charging hole 111, which is beneficial to the sealing of the UAV charging device.

[0103] In some embodiments of the present application, the position adjustment mechanism includes a rotating mechanism 6 and a plurality of lifting mechanisms 3 disposed on the rotating mechanism 6. Each lifting mechanism 3 is provided with a charging unit 41; the rotating mechanism 6 drives the lifting mechanism 3 to rotate to adjust the charging unit 41 to a preset position; the lifting mechanism 3 drives the charging unit 41 to move up and down so that the charging unit 41 can charge the UAV 5.

[0104] In this embodiment, the rotating mechanism 6 includes a rotating table 611 and a third driving member 612 for driving the rotating table 611 to rotate. Among them, the rotating mechanism 6 can be referred to as Figure 13 , Figure 14 As shown, different from the embodiments shown in Figure 13 and Figure 14 , the rotating mechanism 6 is not disposed on the translation mechanism 21. The position of the rotating mechanism 6 can be directly below the charging hole 111, such as directly disposed on the bottom plate 72 of the mounting frame 7. Among them, the charging unit 41 only needs to rotate to be in the preset position, and then through the lifting of the lifting mechanism 3, it is docked with the charging docking unit 54 of the UAV 5 for charging.

[0105] In some embodiments of the present application, the platform module 1 includes at least one parking position (not shown in the figure), and each parking position is used for a UAV 5 to dock.

[0106] In this embodiment, the platform module 1 may include one parking position, and each time it can accommodate one aircraft for docking. The platform module 1 may also include two or more parking positions. Therefore, the platform module 1 can accommodate multiple drones for docking. When the battery life of the drones is insufficient, they can land on the platform module 1 in a timely manner.

[0107] In some embodiments of the present application, when the platform module 1 includes two or more parking positions, each parking position can be used for charging, or some of the parking positions are used for charging.

[0108] In this embodiment, the platform module 1 may include one parking position, which can accommodate one aircraft for docking each time and can charge the aircraft. The platform module 1 may also include two or more parking positions. Therefore, the platform module 1 can accommodate multiple drones for docking. When each parking position can be used for charging, the number of drones that can be charged by the drone charging device can be increased. When some of the parking positions are used for charging, the other parking positions can be used for drones to dock. After a drone finishes charging, some of the docked drones can move to the parking positions available for charging to charge. It can be understood that when multiple drones are charging simultaneously, multiple charging holes 111 can be provided on the fixed platform 11. When the drone charging device does not have enough parking positions for charging, some of the parking positions not used for charging can be used for drones to dock. When there is a charging position available, they can charge. Therefore, this drone charging device can also improve the safety of drones during flight. Even if there are not enough charging positions, it can still provide a place for drones that need to charge to dock and wait for charging.

[0109] It should be noted that as Figure 1b 、 Figure 3 shown, only one of the parking positions is taken as an example to show the basic structure of the fixed platform 11. When the platform module 1 includes multiple parking positions, each parking position can be used for both docking and charging. In this case, the position adjustment mechanism and the charging holes 111 are arranged in one-to-one correspondence with the parking positions. When the platform module 1 includes multiple parking positions, one or several of the parking positions can be used for charging, and the remaining parking positions are only used for docking drones. In this case, the corresponding position adjustment mechanism and charging holes 111 are only provided on the parking positions that can be used for both docking and charging. Of course, the number of the charging holes 111 is not limited to Figure 1b 、 Figure 3Among the two shown, there can also be only one, or more than two. This application does not limit this. In some embodiments of this application, the drone charging device further includes a clamping mechanism (not shown in the figure). The clamping mechanism is arranged on the platform module 1 and is used to fix the drone 5 during charging. In this embodiment, the clamping mechanism can be a pair of clamping plates arranged oppositely along the first horizontal direction X and the second horizontal direction Y. When the drone 5 lands on the platform module 1, the clamping plates move towards each other to clamp the legs or fuselage of the drone 5, maintaining the stability during the drone charging process. Moreover, the clamping mechanism also has a centering function. The position of the drone 5 can be finely adjusted through the clamping plates, so that the docking position of the drone 5 is more accurate.

[0110] In addition, for a drone with leg landing, the fixed platform 11 can be provided with grooves for accommodating the legs. By the movement of the clamping plates, the legs are moved into the grooves, maintaining the accuracy of the docking position of the drone 5, and at the same time, it can also play a role in fixing the drone 5.

[0111] In some embodiments of this application, the drone charging device can be fixed at any position outdoors or indoors. For example, it can be fixed on a street lamp pole or a tower pole outdoors. Among them, the tower pole is similar to the support structure in an overhead transmission line, which is used to fix the drone charging device, or the tower pole is the support structure in the overhead transmission line, which is used to support the conductors and ground wires of the transmission line, maintaining a certain safe distance between them and the ground. Fixing the drone fixing device on this tower pole facilitates charging the drone charging device.

[0112] It can be understood that when the drone charging device includes the mounting bracket 7 as shown in Figure 1a the figure, the mounting bracket 7 can be directly fixed on the street lamp pole or the tower pole. When the drone charging device does not include the mounting bracket 7, the platform module 1 and the position adjustment mechanism can be respectively fixed on the street lamp pole or the tower pole.

[0113] In the embodiments of this application, the power supply of the drone charging device is powered by photovoltaic energy storage or accessed through a wired power line.

[0114] The second aspect of this application provides a method for automatically controlling the charging of a drone, which is used for the interaction including the above-mentioned drone charging device, the drone 5, and the management and control platform; the method includes the following steps:

[0115] S1: When the drone 5 has a charging requirement, the drone 5 sends a charging request signal to the management and control platform. The charging request signal includes the drone identification, model, and current position information. Among them, the drone identification includes identity information, and the model includes the type information of the charging docking unit 54.

[0116] S2: The management and control platform matches a drone charging device for it according to the request signal, and feeds back the location information of the matched drone charging device to the drone 5.

[0117] S3: The drone 5 controls its flight to within a preset range from the drone charging device according to the received location information of the drone charging device, and sends a docking charging request message to the drone charging device.

[0118] S4: After determining that its own conditions are met, the drone charging device sends an allow docking message to the drone 5.

[0119] S5: The drone 5 docks at the designated position of the drone charging device according to the allow docking message.

[0120] S6: The drone charging device controls the position adjustment mechanism to drive the determined charging unit 41 to the designated position, so that the determined charging unit 41 can be docked with the charging docking unit 54 of the drone 5 for charging.

[0121] The determined charging unit 41 is determined by analyzing the charging request signal, and the charging unit 41 matching the model of the drone 5 to be charged is determined from the multiple types of charging units 41. For example, the corresponding charging module type is matched according to the model information, such as a wired charging module or a wireless charging module. Further, the specific interface type of the wired charging module, etc. The matching between the drone model and the charging unit 41 is established through their corresponding relationship.

[0122] In the embodiment of the present application, when the drone 5 needs to be charged, the corresponding charging unit 41 is determined through intelligent communication identification. At the same time, the position adjustment mechanism can adjust the position of the charging unit 41 to adapt to the charging docking unit 54 at different positions and heights of the drone 5 for docking charging, thereby improving the charging autonomy of the drone charging device. Specifically, the management and control platform can match a drone charging device for the drone 5 according to the identity information and current position information of the drone 5. The drone 5 flies to the preset range of the drone charging device according to the information of the received drone charging device and sends a docking charging request signal to the drone charging device. When the drone charging device determines that the current charging conditions are met, it sends an allow docking information. After the drone 5 docks, the drone charging device can automatically match a suitable charging unit 41 according to the type of the drone 5, and adjust the charging unit 41 to an appropriate position through the position adjustment mechanism to dock with the charging docking unit 54. Since the drone charging device has multiple types of charging units 41, it can adapt to multiple types of drones 5, and the position of the charging unit 41 can be adjusted, so as to meet the intelligent matching charging of different types of drones. The technical solution provided by the present application greatly improves the power supply and flight safety of the drone 5 during flight. All the above processes can be automatically completed without the participation of operators, meeting the adaptive charging and flight safety of multiple drones 5. The third aspect of the present application provides a drone automatic charging control system, including a management and control platform and the above-mentioned drone charging device. The management and control platform is used to receive the charging request signal sent by the drone 5, match a drone charging device for it according to the request signal, and feedback the position information of the matched drone charging device to the drone 5.

[0123] The drone charging device is used to receive the docking charging request information sent by the drone 5, and after determining that its own conditions are met, send an allow docking information to the drone 5, and control the position adjustment mechanism to drive the determined charging unit 41 to move to a specified position, so that the determined charging unit 41 can realize docking charging with the charging docking unit 54 of the drone 5.

[0124] In this embodiment, the management and control platform can match the nearest drone charging device for the drone according to the identity information and current position information of the drone, and control the drone charging device to automatically match a suitable charging unit for it, improving the autonomy and convenience of the electronic device. Since the drone charging device includes multiple types of charging units, it can adapt to multiple types of drones 5, and the position of the charging unit 41 can be adjusted, so as to meet the intelligent matching charging of different types of drones. The technical solution provided by the present application greatly improves the power supply and flight safety of the drone 5 during flight. All the above processes can be automatically completed without the participation of operators, meeting the adaptive charging and flight safety of multiple drones 5.

[0125] By applying the drone automatic charging control method and the automatic charging control system provided in the embodiments of the present application, information interaction can be carried out among the management and control platform, the drone 5, and the drone charging device. The drone charging device can automatically match a suitable charging unit 41 for the drone 5 to be charged according to the model of the drone 5, and automatically adjust the position of the matched charging unit 41 through the position adjustment mechanism to dock and charge with the charging docking unit 54 of the drone 5. The whole process can be automatically operated in a unmanned environment, improving the convenience and intelligence of the power supply supplement of the drone 5 in outdoor work, thereby improving the flight efficiency and safety of the drone 5 and reducing the maintenance and use cost of the outdoor work of the drone 5.

[0126] The above are only the preferred embodiments of the present application and are not intended to limit the protection scope of the present application.
