Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of unmanned aerial vehicles, and particularly relates to an unmanned aerial vehicle charging device. BACKGROUND

[0002] The battery capacity of an unmanned aerial vehicle is limited due to the volume restriction, and the unmanned aerial vehicle needs to be charged after working for a period of time. However, the charging method at the present stage cannot charge well and cannot fix tightly.

[0003] The patent for invention with the publication number CN110745239A discloses a mobile power supply device for automatic navigation of a multi-rotor unmanned aerial vehicle. A camera is installed directly below the unmanned aerial vehicle. A landing gear is installed at the bottom of the unmanned aerial vehicle, and a guide block is installed at the end of the landing gear. The guide block is made of a conductive magnetic material. A guide seat is installed on the upper side of the surface of the unmanned vehicle. The position of the guide seat corresponds to the position of the landing gear. The guide seat has an inner cavity with an open top. An electromagnet is installed at the bottom of the inner cavity of the guide seat. When the unmanned aerial vehicle is parked on the unmanned vehicle, the storage battery charges the electric plate on the unmanned aerial vehicle. The unmanned aerial vehicle is provided with a first central controller and a first wireless communication module. The driving motor of the unmanned aerial vehicle is connected to the first central controller. The unmanned vehicle is provided with a second central controller and a second wireless communication module. The driving device of the unmanned vehicle is connected to the second central controller. The unmanned aerial vehicle and the unmanned vehicle maintain real-time communication. The unmanned aerial vehicle flies to the unmanned vehicle through GPS navigation. The present application can solve the problem of mobile charging of the multi-rotor unmanned aerial vehicle.

[0004] The mobile power supply device for automatic navigation of the multi-rotor unmanned aerial vehicle adopts the magnetic attraction mode to connect the guide block of the unmanned aerial vehicle and the guide seat of the unmanned vehicle, so as to realize charging. However, when the unmanned aerial vehicle takes off, the guide block is difficult to separate from the guide seat, causing the problem of difficulty in taking off. SUMMARY

[0005] In order to solve the above problems existing in the prior art, the purpose of the present application is to provide an unmanned aerial vehicle charging device which can guarantee reliable charging and does not affect take-off and landing.

[0006] The technical scheme adopted by the present application is as follows:

[0007] The unmanned aerial vehicle charging device comprises a charging head installed on a landing gear of the unmanned aerial vehicle. The charging head comprises a charging fixing seat. The lower side of the charging fixing seat is connected with a spring. The other end of the spring is connected with a charging copper sheet. The device further comprises a parking apron. The parking apron is provided with a charging contact point matched with the charging copper sheet. The parking apron is further provided with a top plate for pressing the charging head.

[0008] The top plate of the present application presses the charging fixing seat, so that the spring is compressed, the charging copper sheet is pressed against the charging contact point on the parking apron, and reliable charging is guaranteed. When the unmanned aerial vehicle takes off, the top plate moves away, the charging copper sheet can be smoothly separated from the charging contact point, and the influence of the charging device on the take-off and landing of the unmanned aerial vehicle is avoided.

[0009] As a preferred scheme of the present application, a plug screw is threaded on the charging copper sheet, the head of the plug screw is sleeved in the charging fixed seat, and the shank of the plug screw is sleeved in the spring. The plug screw guides the spring, ensures the stable compression of the charging copper sheet and the charging contact, and avoids the deviation of the charging copper sheet in the process of compression.

[0010] As a preferred scheme of the present application, the charging copper sheet is a downward convex curved surface. When the charging copper sheet is a curved surface, the convex position of the charging copper sheet can smoothly contact the charging contact, avoiding the problem of poor contact.

[0011] As a preferred scheme of the present application, the bottom surface of the top plate is an inclined surface, and one side of the top of the charging fixed seat is an inclined surface; when the unmanned aerial vehicle is locked, the inclined surface of the charging fixed seat is compressed with the inclined surface of the top plate. When the bottom surface of the top plate and one side of the charging head are both inclined surfaces, the inclined surface of the top plate gradually compresses the inclined surface of the charging head in the process of moving the top plate towards the charging head, further improving the contact effect of the charging copper sheet and the charging contact.

[0012] As a preferred scheme of the present application, two horizontal movement rods and two vertical movement rods are arranged on the parking apron, the two horizontal movement rods and the two vertical movement rods are synchronously folded towards the center or synchronously dispersed outward, the two horizontal movement rods and the two vertical movement rods are connected with a locking driving mechanism, and the top plate is arranged on the top of the vertical movement rod. The locking driving mechanism drives the two horizontal movement rods and the two vertical movement rods to move synchronously. When the two horizontal movement rods and the two vertical movement rods are synchronously folded towards the center, the bottom of the unmanned aerial vehicle is locked from four directions.

[0013] As a preferred scheme of the present application, a plurality of horizontally arranged and a plurality of vertically arranged limiting grooves are arranged on the parking apron, one end of the horizontal transmission nut connected with the horizontal movement rod passes through the horizontally arranged limiting groove, and the vertical transmission rod passes through the vertically arranged limiting groove; when the horizontal movement rod moves to the inner end of the horizontally arranged limiting groove and the vertical movement rod moves to the inner end of the vertically arranged limiting groove, the two horizontal movement rods and the two vertical movement rods respectively lock the bottom of the unmanned aerial vehicle from four directions and compress the charging contact.

[0014] The transversely arranged limiting grooves limit the transversely moving rods, the longitudinally arranged limiting grooves limit the longitudinally moving rods, and when the two transversely moving rods and the two longitudinally moving rods are driven by a locking driving mechanism, the two transversely moving rods and the two longitudinally moving rods can be set to reach the locking limit position at the same time. Thus, the two transversely moving rods and the two longitudinally moving rods accurately limit the bottom of the unmanned aerial vehicle from four directions. In the space defined by the locking limit position of the two transversely moving rods and the two longitudinally moving rods, a charging contact is arranged corresponding to each charging head of the unmanned aerial vehicle, so that when the unmanned aerial vehicle is accurately locked and positioned, each charging head is reliably charged.

[0015] The application pushes the four charging devices of the unmanned aerial vehicle to the charging contact position through the two transversely moving rods and the two longitudinally moving rods, so that the initial parking position of the unmanned aerial vehicle has low accuracy requirement, and the unmanned aerial vehicle can be quickly landed.

[0016] The end position of the limiting groove needs to meet the following requirements: when the transversely moving rods move close to the inner end of the transversely arranged limiting grooves and the longitudinally moving rods move close to the inner end of the longitudinally arranged limiting grooves, the two transversely moving rods and the two longitudinally moving rods respectively lock the bottom of the unmanned aerial vehicle from four directions. The position of the charging contact needs to meet the following requirements: when the two transversely moving rods and the two longitudinally moving rods lock and position the bottom of the unmanned aerial vehicle, each charging head presses a charging contact.

[0017] As a preferred scheme of the application, the locking driving mechanism comprises a locking motor mounted on one side of the landing apron, and lead screws are rotatably mounted on the front and back sides of the landing apron. One end of one of the lead screws is connected to the output end of the locking motor, the two sections of the lead screw are reversely threaded, and transversely transmission nuts are drivingly connected to the two sections of the lead screw. The transversely moving rods are connected between the transversely transmission nut on the front side of the lead screw and the transversely transmission nut on the back side of the lead screw. Since the two sections of the lead screw are reversely threaded, the locking motor drives the lead screw to rotate, the two transversely transmission nuts on the same lead screw move in opposite directions, and the two transversely moving rods move in opposite directions to lock or release the bottom of the unmanned aerial vehicle in the transverse direction.

[0018] As a preferred scheme of the application, the left and right ends of the lead screws are each provided with a synchronous pulley, a synchronous belt is drivingly connected between the synchronous pulley on the front side of the lead screw and the synchronous pulley on the back side of the lead screw, and longitudinally moving rods are connected between the longitudinally moving rods on the left side of the synchronous belt and the longitudinally moving rods on the right side of the synchronous belt. When the two lead screws rotate, the synchronous belt moves under the drive of the synchronous pulleys, so that the synchronous belt drives the two longitudinally moving rods to move. Since the two longitudinally moving rods are respectively connected to the upper and lower sides of the synchronous belt, the two longitudinally moving rods on the same synchronous belt move in opposite directions, and the two longitudinally moving rods move in opposite directions to lock or release the bottom of the unmanned aerial vehicle in the transverse direction.

[0019] As a preferred scheme of the present application, the transverse movement rod and the longitudinal movement rod are arranged close to the upper surface of the parking apron, the longitudinal movement rod is provided with an avoiding slot, and the transverse movement rod passes through the avoiding slot. The transverse movement rod and the longitudinal movement rod are arranged close to the upper surface of the parking apron, so that the contact distance of the charging head of the unmanned aerial vehicle with the transverse movement rod and the longitudinal movement rod is improved, thereby enabling the charging head to be stably locked and positioned. When the transverse movement rod and the longitudinal movement rod are arranged close to the upper surface of the parking apron, the problem of movement interference between the transverse movement rod and the longitudinal movement rod needs to be considered. However, the present application passes the transverse movement rod through the avoiding slot of the longitudinal movement rod, thereby avoiding the movement interference. In addition, the avoiding slot can also limit the transverse movement rod.

[0020] When the transverse movement rod moves close to the inner end of the avoiding slot, the two transverse movement rods and the two longitudinal movement rods lock the bottom of the unmanned aerial vehicle from four directions, thereby enabling the avoiding slot to also function to accurately position the transverse movement rod.

[0021] As a preferred scheme of the present application, the parking apron is fixed with a bearing seat, and the lead screw is rotationally connected with the bearing seat.

[0022] The present application has the following beneficial effects:

[0023] The top plate of the present application compresses the charging fixing seat, so that the spring is compressed, the charging copper sheet is compressed with the charging contact on the parking apron, and reliable charging is ensured. When the unmanned aerial vehicle takes off, the top plate moves away, and the charging copper sheet can be smoothly separated from the charging contact, thereby avoiding the influence of the charging device on the take-off and landing of the unmanned aerial vehicle.

DETAILED DESCRIPTION

[0033] To make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. The components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0034] Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative labor are within the scope of protection of the present application. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0035] As shown in Figure 1 The unmanned aerial vehicle 1 comprises a movement assembly 12, an unmanned aerial vehicle body 14 and a landing gear 13. The landing gear 13 comprises two bottom rods, and one charging head 11 is installed at each end of the two bottom rods.

[0036] As shown in Figures 1-4 The unmanned aerial vehicle charging device of the embodiment comprises the charging head 11 installed on the landing gear 13 of the unmanned aerial vehicle 1. The charging head 11 comprises a charging fixing seat 111, the lower side of the charging fixing seat 111 is connected with a spring 112, and the other end of the spring 112 is connected with a charging copper sheet 113. The parking apron 2 is further provided with the charging contact 21 matched with the charging copper sheet 113, and the top plate 42 for pressing the charging head 11 is further provided on the parking apron 2.

[0037] The top plate 42 of this invention presses the charging mounting base 111 tightly, thereby compressing the spring 112 and pressing the charging copper sheet 113 against the charging contact 21 on the landing pad 2, ensuring reliable charging. When the drone 1 takes off, the top plate 42 is removed, and the charging copper sheet 113 can be smoothly separated from the charging contact 21, avoiding the charging device from affecting the take-off and landing of the drone 1.

[0038] To ensure accurate guidance, a screw threaded onto the charging copper plate 113 is provided. The head of the screw threaded onto the charging mounting base 111 is fitted inside the charging mounting base 111, and the shaft of the screw threaded onto the spring 112. The screw threaded onto the spring 112 guides the charging copper plate 113, ensuring that the charging copper plate 113 is smoothly pressed against the charging contact 21, and preventing the charging copper plate 113 from shifting during the pressing process.

[0039] The charging copper sheet 113 has a downwardly convex curved surface. When the charging copper sheet 113 is curved, the convex position of the charging copper sheet 113 can make smooth contact with the charging contact 21, avoiding the problem of poor contact.

[0040] The charging mounting base 111 is a curved surface with an opening at the bottom. The charging copper sheet 113 is fitted inside the charging mounting base 111. An end cap 115 is connected to the charging mounting base 111. The end cap 115 and the charging mounting base 111 protect the charging copper sheet 113.

[0041] The bottom surface of the top plate 42 is inclined, and one side of the top of the charging mounting base 111 is also inclined. When locking the drone 1, the inclined surface of the charging mounting base 111 presses against the inclined surface of the top plate 42. When both the bottom surface of the top plate 42 and one side of the charging head 11 are inclined, as the top plate 42 moves toward the charging head 11, the inclined surface of the top plate 42 gradually presses against the inclined surface of the charging head 11, further improving the contact effect between the charging copper sheet 113 and the charging contact 21.

[0042] like Figures 5-8 As shown, to reliably lock the drone 1, the landing pad 2 is equipped with two horizontal moving rods 3 and two vertical moving rods 4. The two horizontal moving rods 3 and two vertical moving rods 4 synchronously converge towards the center or synchronously disperse outwards. The two horizontal moving rods 3 and two vertical moving rods 4 are connected to a locking drive mechanism 5, and a top plate 42 is located on top of the vertical moving rods 4. The locking drive mechanism 5 drives the two horizontal moving rods 3 and two vertical moving rods 4 to move synchronously. When the two horizontal moving rods 3 and two vertical moving rods 4 synchronously converge towards the center, the bottom of the drone 1 is locked from four directions.

[0043] The locking drive mechanism 5 is installed on the bottom surface of the landing pad 2 to prevent the locking drive mechanism 5 from interfering with the lateral movement rod 3, the longitudinal movement rod 4 and the UAV 1.

[0044] In order to accurately position the unmanned aerial vehicle 1, a plurality of transversely arranged and longitudinally arranged limiting grooves 22 are arranged on the parking apron 2, one end of the transverse movement rod 3 is connected with the transversely arranged limiting groove 22 through the transverse transmission nut 53, and the longitudinal transmission rod 56 is connected with the longitudinally arranged limiting groove 22; when the transverse movement rod 3 is moved to the inner end of the transversely arranged limiting groove 22 and the longitudinal movement rod 4 is moved to the inner end of the longitudinally arranged limiting groove 22, the two transverse movement rods 3 and the two longitudinal movement rods 4 respectively lock the bottom of the unmanned aerial vehicle 1 from four directions and press the charging head 11 to the charging contact 21.

[0045] The transversely arranged limiting groove 22 limits the transverse movement rod 3, the longitudinally arranged limiting groove 22 limits the longitudinal movement rod 4, and when the two transverse movement rods 3 and the two longitudinal movement rods 4 are driven by a locking drive mechanism 5, the two transverse movement rods 3 and the two longitudinal movement rods 4 can be arranged to reach the locking limit position at the same time. Therefore, the two transverse movement rods 3 and the two longitudinal movement rods 4 accurately limit the bottom of the unmanned aerial vehicle 1 from four directions. In the space defined by the locking limit position of the two transverse movement rods 3 and the two longitudinal movement rods 4, the charging contact 21 corresponding to each charging head 11 of the unmanned aerial vehicle 1 is arranged, so that when the unmanned aerial vehicle 1 is accurately locked and positioned, each charging head 11 can be reliably charged.

[0046] The present application pushes the four charging devices of the unmanned aerial vehicle 1 to the charging contact 21 position through the two transverse movement rods 3 and the two longitudinal movement rods 4, so that the initial parking position of the unmanned aerial vehicle 1 has low accuracy requirement, and the unmanned aerial vehicle 1 can be quickly landed.

[0047] It should be noted that the end position of the limiting groove 22 needs to meet the following requirements: when the transverse movement rod 3 is moved to the inner end of the transversely arranged limiting groove 22 and the longitudinal movement rod 4 is moved to the inner end of the longitudinally arranged limiting groove 22, the two transverse movement rods 3 and the two longitudinal movement rods 4 respectively lock the bottom of the unmanned aerial vehicle 1 from four directions. The position of the charging contact 21 needs to meet the following requirements: when the two transverse movement rods 3 and the two longitudinal movement rods 4 lock and position the bottom of the unmanned aerial vehicle 1, each charging head 11 presses one charging contact 21.

[0048] Specifically, as Figure 8As shown, the locking driving mechanism 5 comprises a locking motor 51 mounted on one side of the parking apron 2, and two lead screws 52 rotatably mounted on the front and back sides of the parking apron 2, one end of one of the lead screws 52 is connected with the output end of the locking motor 51, and a bearing seat 57 is fixed on the parking apron 2, and the lead screw 52 is rotatably connected with the bearing seat 57. The two sections of the lead screw 52 are reversely threaded, and the two sections of the lead screw 52 are both drivingly connected with a transverse transmission nut 53, and the transverse movement rod 3 is connected between the transverse transmission nut 53 on the front side of the lead screw 52 and the transverse transmission nut 53 on the back side of the lead screw 52. The left and right ends of the lead screw 52 are both mounted with a synchronous belt pulley 54, the synchronous belt pulley 54 on the front side of the lead screw 52 is drivingly connected with the synchronous belt pulley 54 on the back side of the lead screw 52 through a synchronous belt 55, and the upper and lower sides of the synchronous belt 55 are both connected with a longitudinal transmission rod 56, and the longitudinal movement rod 4 is connected between the longitudinal transmission rod 56 on the left side of the synchronous belt 55 and the longitudinal transmission rod 56 on the right side of the synchronous belt 55.

[0049] Since the two sections of the lead screw 52 are reversely threaded, the locking motor 51 drives the lead screw 52 to rotate, and the two transverse transmission nuts 53 on the same lead screw 52 move reversely, so that the two transverse movement rods 3 move in opposite directions, and the bottom of the unmanned aerial vehicle 1 can be locked and positioned or released in the transverse direction.

[0050] When the two lead screws 52 rotate, the synchronous belt 55 moves under the drive of the synchronous belt pulley 54, so that the synchronous belt 55 drives the two longitudinal transmission rods 56 to move. Since the two longitudinal transmission rods 56 are respectively connected to the upper and lower sides of the synchronous belt 55, the two longitudinal transmission rods on the same synchronous belt 55 move in opposite directions, and then the two longitudinal movement rods 4 move in opposite directions, so that the bottom of the unmanned aerial vehicle 1 can be locked and positioned or released in the transverse direction.

[0051] Further, as shown, Figure 6 The transverse movement rod 3 and the longitudinal movement rod 4 are both arranged close to the upper surface of the parking apron 2, the longitudinal movement rod 4 is provided with an avoiding slot 41, and the transverse movement rod 3 passes through the avoiding slot 41. The transverse movement rod 3 and the longitudinal movement rod 4 are both arranged close to the upper surface of the parking apron 2, the contact distance between the charging head 11 of the unmanned aerial vehicle 1 and the transverse movement rod 3 and the longitudinal movement rod 4 is improved, so that the charging head 11 can be stably locked and positioned. When the transverse movement rod 3 and the longitudinal movement rod 4 are arranged close to the upper surface of the parking apron 2, the problem of movement interference between the transverse movement rod 3 and the longitudinal movement rod 4 needs to be considered. However, the transverse movement rod 3 passes through the avoiding slot 41 of the longitudinal movement rod 4, so that the movement interference is avoided. Moreover, the avoiding slot 41 can also limit the transverse movement rod 3.

[0052] When the lateral movement rods 3 move to the inner end of the avoiding groove 41, the two lateral movement rods 3 and the two longitudinal movement rods 4 lock the bottom of the unmanned aerial vehicle 1 from four directions respectively, so that the avoiding groove 41 also plays a role in accurately positioning the lateral movement rods 3.

[0053] The present application is not limited to the above-mentioned optional embodiments, and anyone can derive other various forms of products under the inspiration of the present application, but regardless of any changes in shape or structure, any technical solutions falling within the scope defined by the claims of the present application fall within the protection scope of the present application.
