Description

Technical Field

[0001] The present invention relates to the technical field of charging equipment, and in particular to a positioning charging mechanism, an unmanned equipment parking platform and a system. Background Art

[0002] Unmanned driving equipment is a device that integrates many high technologies such as artificial intelligence, computer vision, integrated navigation, information fusion, automatic control and architecture.

[0003] Unmanned devices include unmanned vehicles and unmanned aerial vehicles, which can move in the air (e.g., fixed-wing aircraft, rotary-wing aircraft, or aircraft with neither fixed wings nor rotary wings), on land (e.g., cars), etc. Unmanned devices generally use batteries as the power source of their power systems. Therefore, the capacity of the battery is an important reference factor for the endurance of unmanned devices. Due to the limited capacity of the battery, the battery of the unmanned device needs to be replaced or charged every time the battery is exhausted.

[0004] The existing solution to achieve automatic remote operation of unmanned equipment is to configure charging stations for unmanned equipment, so that the unmanned equipment can be automatically charged through the charging stations. After the power is replenished, the unmanned equipment can automatically operate according to the pre-planned operation route. The power replenishment methods of unmanned equipment mainly include battery replacement, contact charging and contactless charging.

[0005] During the charging process of unmanned equipment, since there is no manual operation assistance, the unmanned equipment needs to be accurately parked in the charging area of ​​the charging station. The charging device in the charging area can then be electrically connected to the unmanned equipment to charge it. This places high demands on the software and hardware of the unmanned equipment and the charging station, and it is necessary to increase the complexity of the equipment to improve the operational precision and positioning accuracy.

[0006] In summary, there is an urgent need for a charging device with a simple structure and precise positioning for unmanned equipment to park and charge. Summary of the invention

[0007] One of the purposes of the embodiments of the present invention is to provide a positioning charging mechanism to solve the technical problem that it is difficult to charge the unmanned equipment when the parking position of the unmanned equipment is deviated.

[0008] The second purpose of the embodiment of the present invention is to provide an unmanned equipment parking platform, reduce the positioning accuracy requirements of the unmanned equipment on the parking platform, and improve the charging efficiency of the unmanned equipment.

[0009] The third purpose of the embodiment of the present invention is to provide an unmanned equipment parking system by means of a support part arranged on the unmanned equipment, so that the guide part can more easily guide the parking position of the unmanned equipment, thereby overcoming the above-mentioned problems existing in the prior art.

[0010] To achieve one of the above purposes, the present invention adopts the following technical solutions:

[0011] In a first aspect, a positioning charging mechanism is provided, comprising a support plate defining a charging area; a guide portion, arranged on the support plate and surrounding a circumference of the charging area, for guiding a device to be charged parked on the guide portion to move into the charging area; a charger; a linkage mechanism, arranged in the charging area, comprising a linkage portion and a pressing portion connected to each other, the linkage portion being used to drive the charger to move relative to the support plate; when a device to be charged is parked in the charging area, the linkage mechanism is in a charging position, the device to be charged contacts the pressing portion, so that the linkage portion drives the charger to approach the device to be charged and electrically connects to the device to be charged; when the device to be charged is not parked in the charging area, the linkage mechanism is in a standby position, the pressing portion is not contacted by the device to be charged, so that the linkage portion and the charger are restored to an initial state.

[0012] In order to achieve the second of the above-mentioned objectives, the present invention adopts the following technical solutions:

[0013] In a second aspect, an unmanned equipment parking platform is provided, comprising a base, the interior of which is hollow to form an installation cavity, and the top of the base is provided with an opening connected to the installation cavity; a battery is arranged in the installation cavity and electrically connected to the charger; a charging device is arranged on the base and electrically connected to the battery; and the positioning charging mechanism as described above, the support plate is connected to the base and covers the opening.

[0014] In order to achieve the third of the above objectives, the present invention adopts the following technical solutions:

[0015] According to a third aspect, an unmanned equipment parking system is provided, characterized in that it includes the unmanned equipment parking platform as described above; the equipment to be charged is provided with a support portion, and the support portion is used to support the equipment to be charged; when the equipment to be charged is not completely parked in the charging area, and the support portion is placed on the guide portion, the guide portion is used to guide the support portion to guide the equipment to be charged to a position where it is completely parked in the charging area; the equipment to be charged is also provided with a charging portion, and when the linkage mechanism is in the charging position, the charger is electrically connected to the charging portion.

[0016] The beneficial effects of the present invention are as follows: the positioning charging mechanism of the present invention, by arranging the guide part on the support plate, allows the guide part to surround and define the charging area, so that when the unmanned equipment enters the charging area for charging, even if it is not completely and accurately parked in the corresponding charging area, the guide part located at the periphery of the charging area will guide the unmanned equipment to be charged toward the charging area, and the unmanned equipment is physically assisted in parking and guiding by the guide part, thereby reducing the positioning accuracy requirements for the unmanned equipment during the parking process, making the parking process of the unmanned equipment shorter, thereby improving the charging efficiency of the unmanned equipment;

[0017] When the unmanned equipment to be charged is completely parked in the charging area, the unmanned equipment contacts the pressing part of the linkage mechanism, so that the linkage part drives the charger to charge the unmanned equipment, thereby ensuring accurate electrical connection between the unmanned equipment to be charged and the charger; and when the unmanned equipment is fully charged and needs to perform the next round of operation, the unmanned equipment leaves the charging area and separates from the pressing part, so that the linkage part and the charger return to their initial state. In this way, when the unmanned equipment parking platform is in the standby state and during the parking process of the unmanned equipment, the charger can be protected to avoid contact between external objects or the unmanned equipment during the parking process and the charger, thereby improving the safety of the unmanned equipment parking platform and the system.

[0032] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention are further described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0033] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0035] like Figure 1-Figure 10 As shown, this embodiment provides a positioning charging mechanism, which aims to reduce the positioning accuracy of unmanned equipment during automatic parking, so that the unmanned equipment can still achieve electrical connection with the charger 30 when the parking accuracy is low, and complete the charging of the equipment. The positioning charging mechanism described in this embodiment can be applied to various equipment charging platforms, specifically to the remote operation charging platform of unmanned equipment, providing a parking platform close to the work site for remote operation unmanned equipment, reducing the distance between the work site and the charging platform, reducing the round-trip time of unmanned equipment, and improving the operation efficiency of unmanned equipment.

[0036] The unmanned equipment described in this embodiment can move in any suitable environment, such as in the air (for example, a fixed-wing aircraft, a rotary-wing aircraft, or an aircraft with neither fixed wings nor rotary wings), on land (for example, a car), and any combination of the above various environments. The unmanned equipment in this embodiment specifically takes the unmanned aerial vehicle 60 as an example. It can be understood that the type of the unmanned equipment can also be other devices mentioned above, which cannot be understood as a limitation of the present invention. Specifically, the unmanned aerial vehicle can be a multi-rotor unmanned aerial vehicle, such as a four-rotor unmanned aerial vehicle, a six-rotor unmanned aerial vehicle, an eight-rotor unmanned aerial vehicle, a twelve-rotor unmanned aerial vehicle, etc. The unmanned aerial vehicle can be used to carry a load to complete a predetermined task, such as carrying an imaging device for shooting, carrying pesticides, nutrient solution and spraying devices to perform plant protection tasks, and can also be used in other fields such as geographic surveying and mapping, aerial photography, power inspection, environmental monitoring and disaster inspection.

[0037] like Figure 2-Figure 5 As shown, the positioning charging mechanism includes a support plate 10, on which the unmanned equipment can be parked, and a charging area 11 for charging the unmanned equipment is defined on the support plate 10, and a guide portion 12 is provided around the charging area 11, and the guide portion 12 is provided on the support plate 10. The size of the charging area 11 can be defined by the range formed by the guide portion 12. When the unmanned equipment is not accurately and completely parked in the charging area 11, and is partially placed on the guide portion 12, the guide portion 12 can guide the unmanned equipment to be charged, and guide the unmanned equipment to be accurately placed in the charging area 11 for charging.

[0038] The positioning charging platform of this embodiment cooperates with the unmanned equipment through the guide part 12. The unmanned aerial vehicle 60 or the unmanned vehicle can use technology such as machine vision to perform fixed-point landing or parking without human operation. After the unmanned aerial vehicle 60 or the unmanned vehicle is parked and loses the power applied to it by the power system, the guide part 12 can guide the unmanned equipment, allowing the unmanned equipment to move in the direction of gravity and the direction guided by the guide part 12, so as to realize the positioning of the unmanned equipment in the charging area 11. The structure is simple, and the parking error range of the unmanned equipment is expanded. The unmanned aerial vehicle 60 and the vehicle can be accurately positioned on the support plate 10 without the need for a high-precision mechanical arm or a positioning and navigation module. On the one hand, the equipment cost and complexity of the unmanned equipment parking platform are reduced, and on the other hand, the accuracy requirements for the navigation and positioning equipment of the unmanned equipment in the unmanned equipment parking system are reduced. It has strong versatility and a wider range of applications.

[0039] A linkage mechanism 20 is provided in the charging area 11, and a linkage portion 21 and a pressing portion 22 are formed on the linkage mechanism 20. The linkage mechanism 20 is mainly used to control the movement and position state of the charger 30. The charger 30 can be provided on the linkage portion 21, or can be supported and positioned at the linkage portion 21 by other supporting components, so that the linkage portion 21 drives the charger 30 to move relative to each other during the movement. The linkage mechanism 20 can be provided on the support plate 10, or can be installed in the guide portion 12.

[0040] The linkage mechanism 20 is specifically described in different positions. The linkage mechanism 20 includes a charging position for charging unmanned equipment and a standby position in a non-working, charging state:

[0041] When the unmanned device to be charged is parked in the charging area 11, the linkage mechanism 20 is in the charging position, and the device to be charged contacts the pressing portion 22 in the charging area 11, so that the linkage portion 21 drives the charger 30 to move relative to the support plate 10, close to the unmanned device, and realizes electrical connection with the unmanned device to be charged, thereby ensuring the electrical connection strength between the charger 30 and the battery 53 of the unmanned device;

[0042] When the unmanned equipment is fully charged or the next round of operation is required after the standby is completed, the unmanned equipment drives away from the support plate 10 and the charging area 11. There is no unmanned equipment to be charged parked in the charging area 11. The linkage mechanism 20 is in the standby position. The pressing part 22 is not contacted by the equipment to be charged, so that the linkage part 21 is not driven by the linkage mechanism 20 or does not receive the driving instruction triggered by the pressing part 22. The linkage part 21 drives the charger 30 to restore to the initial state, and assists the charger 30 to separate from the unmanned equipment when the unmanned equipment drives away from the charging area 11. At the same time, it should be noted that when the linkage part 21 and the charger 30 are in the initial state, the horizontal height of the charger 30 is less than the horizontal height of the charger 30 at the charging position. In this way, the charger 30 can be better protected in the non-charging state, and the risk of collision between the unmanned equipment and the charger 30 during the parking process can be reduced or avoided, thereby reducing the damage rate of the unmanned equipment parking platform and the system, and reducing the work intensity of maintenance and repair personnel. In the absence of external force pressing the pressing part 22, the linkage mechanism 20 remains in the initial state.

[0043] Based on the above-mentioned positioning and charging mechanism, this embodiment also provides an unmanned equipment parking platform, which is used to start and stop unmanned equipment, detect the flight and driving environment of unmanned equipment, and charge unmanned equipment. It can be set in the waiting area of ​​​​unmanned equipment, such as farmland and orchards. In this embodiment, the unmanned equipment parking platform can be connected to the control terminal for communication, and the user can send control instructions to the unmanned equipment through the control terminal at any time to let it operate. After the unmanned equipment is completed, the unmanned equipment can be parked in the unmanned equipment parking platform. Thus, the unmanned equipment parking platform can provide protection for the unmanned equipment, and there is no need to carry and transfer the unmanned equipment, and the operation efficiency is high. Of course, the unmanned equipment can automatically fly and operate according to the settings when it meets the take-off and driving environment.

[0044] like Figure 6As shown, the unmanned equipment parking platform includes a base 50, a battery 53 and the above-mentioned positioning charging mechanism. The inner hollow of the base 50 forms an installation cavity 51 for installing the hardware equipment required for the parking platform. The top of the base 50 is provided with an opening 52 connected to the installation cavity 51. The opening 52 can facilitate the installation, maintenance and replacement of the hardware equipment in the installation cavity 51. A battery 53 is installed in the installation cavity 51. In this embodiment, the battery 53 is electrically connected to the charger 30. A charging device is also provided on the base 50. The charging device is electrically connected to the battery 53 and the external power supply respectively. When the unmanned equipment parking platform is powered normally, the battery 53 supplies power to the charger 30 normally through the charging device connected to the external power supply. At the same time, the battery 53 stores a certain amount of electric energy through the charging device. When the external power supply is cut off, the battery 53 can provide emergency power for the charger 30 and other live working equipment of the unmanned equipment parking platform, ensuring that the parking platform can still operate normally in the case of a short-term power outage. Of course, the battery 53 can also be directly connected to an external power supply, and the charging device can be two charging circuits independent of the battery 53. The external power supply is directly connected to the charger 30 through the charging device. Under normal power supply conditions, the charging device is enabled to power the charger 30. Under power-off conditions, the battery 53 is enabled to power the charger 30.

[0045] The above-mentioned positioning charging mechanism is arranged on the base 50, the support plate 10 is connected to the base 50 and covers the opening 52, a bin cover 54 is pivotally connected to the base 50 and moves in the direction of opening or closing through the bin cover 54 to open or cover the support plate 10, and a receiving cavity 55 for receiving unmanned equipment is formed between the support plate 10 and the bin cover 54 in the closed state. A photovoltaic panel 541 electrically connected to the battery 53 is arranged on the top of the bin cover 54, which converts solar radiation energy directly or indirectly into electrical energy through the photoelectric effect or the photochemical effect to charge the battery 53.

[0046] A driving member for driving the bin cover 54 to open or close may also be provided in the installation cavity 51. In the present embodiment, there are two bin covers 54, which are pivotally connected to opposite sides of the base 50, and can move in directions approaching and moving away from each other to achieve complete closure or opening of the bin cover 54. Correspondingly, the number of driving members matches the number of bin covers 54, and the two driving members are used to drive the opening and closing of the two bin covers 54, respectively.

[0047] Preferably, the driving member is a telescopic rod, one end of which is rotatably connected to the bin cover 54, and the other end is rotatably and detachably mounted in the mounting cavity 51. Since the bin cover 54 is detachably and rotatably connected to the mounting cavity 51 of the base 50, the opening and closing of the bin cover 54 is controlled by the extension and contraction of the telescopic rod, and the telescopic rod can be one or a combination of two of an electric telescopic rod, a pneumatic telescopic rod, and a hydraulic telescopic rod. It can be understood that the present application does not specifically limit the type of telescopic rod. In the present embodiment, the telescopic rod is an electric telescopic rod, which is also called an electric push rod. It is an electric drive device that converts the rotational motion of a motor into the linear reciprocating motion of a push rod. It is used as an execution machine in the process flow to achieve remote control, centralized control or automatic control.

[0048] The specific structure and installation method of the telescopic rod are common knowledge to those skilled in the art and will not be described in detail here.

[0049] A travel switch is also provided in the installation cavity 51, which is used to detect the open state or closed state of the bin cover 54. Furthermore, corresponding to the number of bin covers 54, at least two travel switches are provided inside the installation cavity 51, and the travel switch can be passed through the installation cavity 51 on the support plate 10, so as to detect whether the bin cover 54 is completely closed. The travel switch can also be provided in the installation cavity 51 to cooperate with the driving member. When the electric push rod as the driving member opens the bin cover 54, the electric push rod will squeeze the travel switch located in the installation cavity 51, so as to detect whether the bin cover 54 is completely opened, thereby avoiding obstacles to the unmanned equipment caused by the bin cover 54 not being opened.

[0050] Furthermore, the unmanned equipment parking platform is also provided with a smoke sensor, a temperature and humidity sensor, and a smoke sensor. The smoke sensor, the temperature and humidity sensor, and the smoke sensor are used to detect the environment inside and around the unmanned equipment parking platform. In addition, the external environment of the unmanned equipment parking platform can also be monitored by a camera, a temperature sensor, and a wind speed sensor.

[0051] In accordance with the above, the unmanned equipment parking platform also includes a parking status camera (not shown), which is used to observe the parking environment of the unmanned equipment.

[0052] Here, in order to improve the heat insulation performance of the unmanned equipment parking platform and reduce the difficulty of pre-processing, the base 50, the support plate 10 and the bin cover 54 can be integrally formed by rotational molding or injection molding. Preferably, the base 50, the support plate 10 and the bin cover 54 are hollow structures. When the unmanned equipment parking platform is set in an outdoor environment, the hollow grooves formed in the base 50, the support plate 10 and the bin cover 54 can be heat-insulated to prevent the electronic equipment in the unmanned equipment parking platform from being damaged by heat. A warning light can also be provided on the base 50 to facilitate the staff to find the unmanned equipment parking platform placed in the working environment and indicate the environmental conditions in the installation cavity 51.

[0053] In addition, the base 50 in this embodiment is roughly formed into a square shell structure, and the bottom of the base 50 is supported by four supporting legs 56.

[0054] Based on the above unmanned equipment parking platform, this embodiment also provides an unmanned equipment parking system, including the above unmanned equipment parking platform, the equipment to be charged, the equipment to be charged described here is the above unmanned equipment, it should be noted that the equipment to be charged described in this embodiment is another name for the unmanned equipment, the above and the equipment to be charged described later, for the convenience of explanation and understanding, can be understood as the above unmanned equipment in this embodiment, which can be an unmanned equipment that has been charged or to be charged, or an unmanned equipment that is being charged, the unmanned equipment is provided with a support part 61, the support part 61 is used to support the unmanned equipment and cooperate with the guide part 12 for guidance, when the equipment to be charged is not completely parked in the charging area 11, the support part 61 is located in the guide part 12, the guide part 12 is used to guide the support part 61, so as to guide the equipment to be charged to a position where it is completely parked in the charging area 11. The equipment to be charged is also provided with a charging part 62 electrically connected to its internal power supply, and when the linkage mechanism 20 is in the charging position, the charger 30 is electrically connected to the charging part 62.

[0055] When the unmanned equipment is an unmanned aerial vehicle 60, the support part 61 can be a tripod 65 of the unmanned aerial vehicle 60. When the unmanned equipment is an unmanned vehicle, the support part 61 can be a wheel or a support frame extending from the vehicle chassis, so that the unmanned vehicle can be supported by the support frame after the wheel leaves the ground and achieve coordinated guidance with the guide part 12.

[0056] When the unmanned equipment needs to land on the unmanned equipment parking platform, the communication module on the parking platform will send the location information of the parking platform to the unmanned equipment, so that the unmanned equipment can drive to the parking platform according to the location information and park on the charging area 11 and / or the guide part 12. In this way, the unmanned equipment can move along the guide direction and the guide part 12 to the charging area 11 for positioning and charging.

[0057] The unmanned equipment parking positioning and charging method of the unmanned equipment parking system mentioned above includes:

[0058] S10, the unmanned equipment parking platform sends the platform location information to the unmanned equipment through the communication module;

[0059] S20, the unmanned equipment drives to the unmanned equipment parking platform according to the location information;

[0060] S30, the unmanned equipment lands on the support plate 10 by driving or flying, and parks as close to the charging area 11 as possible;

[0061] S40, when the unmanned equipment is partially parked on the guide portion 12, the unmanned equipment can be moved along the direction guided by the guide portion 12 through the support portion 61 to a position completely placed in the charging area 11;

[0062] S50, the unmanned device contacts the pressing part 22, so that the linkage part 21 linked thereto drives the charger 30 to approach the unmanned device and electrically connects with the power supply 67 of the unmanned device to charge it;

[0063] S60, when the unmanned device leaves the unmanned device parking platform, the unmanned device disengages from the pressing portion 22, allowing the linkage portion 21 linked thereto to drive the charger 30 to move away from the unmanned device, and disconnect from the power supply 67 of the unmanned device.

[0064] like Figure 3 As shown, the specific structure of the unmanned aerial vehicle 60 is further described below by taking the unmanned equipment as an unmanned aerial vehicle 60 as an example. The unmanned aerial vehicle 60 includes a fuselage 63, an arm 64, a tripod 65, a power assembly 66, and a power source 67. In this embodiment, the unmanned aerial vehicle 60 is a quad-rotor unmanned aerial vehicle 60, so the corresponding number of power assemblies 66 is four, and the four power assemblies 66 are distributed in a rectangular area around the fuselage 63 through the support of the arm 64, and each power assembly 66 is located at a vertex of the rectangle.

[0065] Of course, according to different needs, the number of power components 66 can be appropriately changed. For example, the number of power components 66 can be two, three, six, etc., or even the number of power components 66 can be only one. Accordingly, the number of arms 64 can also be reasonably set according to the number of power components 66.

[0066] Moreover, depending on the application field of the UAV 60, the fuselage 63 may also carry other loads capable of achieving specific tasks. For example, when the UAV 60 is used for aerial photography or surveying, the fuselage 63 may carry a shooting device equipped with a stabilizing gimbal. When the UAV 60 is used in the agricultural field for sowing and spraying pesticides on crops, the fuselage 63 may carry a box for storing seeds or pesticides.

[0067] like Figure 3 As shown, a fixed compartment 68 is provided at the rear of the fuselage 63, a power supply 67 for powering the unmanned aerial vehicle 60 is arranged in the fixed compartment 68, and a charging unit 62 is formed at the lower part of the unmanned aerial vehicle 60, that is, the side of the unmanned aerial vehicle facing the ground when the unmanned aerial vehicle is in use.

[0068] The arm 64 is rotatably connected to the side of the fuselage 63, and is used to support the power assembly 66 and distribute the power assembly 66 around the fuselage 63 in a predetermined pattern. Here, the power assembly 66 generally includes a motor and a rotor. The housing of the motor is fixed to the end of the arm 64, and the rotor is set on the output shaft of the motor. The motor rotates to rotate the rotor, and finally drives the fuselage 63 to rise or fall. Since the arm 64 can be rotatably connected to the side of the fuselage 63, the arm 64 can adjust different positions and states relative to the fuselage 63.

[0069] Further, the machine arm 64 includes a main arm 641 and a support arm 642 connected to the main arm 641. One end of the main arm 641 is rotatably connected to the fuselage 63, and the other end is connected to the support arm 642. In this embodiment, the main arm 641 and the support arm 642 are roughly connected in a "T" shape. In this embodiment, taking the above-mentioned machine arm 64 structure as an example, the number of main arms 641 is two, and the two main arms 641 are respectively connected to the opposite sides of the fuselage 63. Each main arm 641 is connected to two support arms 642, and the two support arms 642 are coaxially arranged and respectively located on both sides of the main arm 641. In this embodiment, the support arms 642 on both sides of each main arm 641 can be connected as a whole, and the support arms 642 are shown as an integral long arm. The support arms 642 fix the end of the main arm 641 away from the fuselage 63 through a connecting kit. The main arm 641 is connected to the roughly middle position of the support arm 642, and the support arm 642 is roughly perpendicular to the main arm 641. Both ends of the support arm 642 are respectively formed with fixing seats 643 for mounting the power assembly 66 .

[0070] The tripod 65 is used as a support for the UAV 60 when landing. In this embodiment, there are four tripods 65 , which are respectively disposed at the ends of the supporting arms 642 and pivotally connected to the fixing base 643 .

[0071] The power source 67 is disposed in a fixed compartment 68 at the rear of the body 63. The rear of the power source 67 protrudes from the fixed compartment 68 and a charging portion 62 is formed at the lower end. The charging portion 62 described here can be a charging terminal through plug-in matching, or a charging plate through wireless charging. Figure 3 As shown in FIG. 6 , the charging portion 62 is a charging terminal that slightly protrudes from the fixing compartment 68 .

[0072] As a preferred embodiment of the positioning charging mechanism, the support plate 10 in this embodiment is penetrated by a charging hole 13 and a trigger hole 14. The charging hole 13 and the trigger hole 14 are two through holes set at intervals and respectively opened on the support plate 10. The charging hole 13 and the trigger hole 14 can also be combined into a large through hole, so that the through hole can realize the functions of both the charging hole 13 and the trigger hole 14. The linkage mechanism 20 is arranged at the lower part of the support plate 10 and is located between the charging hole 13 and the trigger hole 14. Preferably, the linkage mechanism 20 is arranged at the lower part of the support plate 10, that is, in the installation cavity 51. The linkage mechanism 20 can be specifically arranged at the lower part of the guide portion 12 or directly at the lower part of the support plate 10.

[0073] When the linkage mechanism 20 is arranged at the lower part of the support plate 10, the charging hole 13 and the trigger hole 14 are both arranged on the support plate 10; when the linkage mechanism 20 is arranged at the lower part of the guide portion 12, the trigger hole 14 is arranged at the bottom of the guide portion 12, and the charging hole 13 is arranged on the support plate 10.

[0074] Specifically, the pressing portion 22 is arranged opposite to the trigger hole 14 so that the pressing portion 22 can at least partially extend out of the support plate 10 from the trigger hole 14, or the device to be charged can contact the pressing portion 22 through the trigger hole 14; the charger 30 is arranged opposite to the charging hole 13 so that the charger 30 can extend out of or retract into the charging hole 13 according to the position state of the linkage mechanism 20.

[0075] In this embodiment, three implementations of the linkage mechanism 20 are provided:

[0076] like Figure 7-Figure 10 The figure shows a preferred implementation of the present scheme, in which the linkage mechanism 20 is specifically a lever mechanism, which includes a tilting rod 23, which is movably arranged on the support plate 10 and can swing relative to the support plate 10, and a linkage portion 21 and a pressing portion 22 are formed at opposite ends of the tilting rod's swing axis, respectively, and the pressing portion 22 is connected to the linkage portion 21. When the unmanned device is parked at the charging position, the pressing portion 22 can be pushed, so that the tilting rod 23 drives the linkage portion 21 to approach the unmanned device.

[0077] In this embodiment, the linkage mechanism 20 is set in the installation cavity 51 as an example. When the trigger hole 14 is set at the bottom of the guide part 12 and the charging hole 13 is set on the support plate 10, the tilting rod 23 can be pivotally set at the lower part of the support plate 10 or the lower part of the guide part 12. The tilting rod 23 is located at one end of the linkage part 21, facing the charging hole 13 set at the bottom of the guide part 12, and the tilting rod 23 is located at one end of the pressing part 22, facing the trigger hole 14 set on the support plate 10; when the trigger hole 14 and the charging hole 13 are both set on the support plate 10, the tilting rod 23 is pivotally set at the lower part of the support plate 10, and the two ends of the tilting rod 23, namely the linkage part 21 and the pressing part 22 are respectively set opposite to the charging hole 13 and the trigger hole 14 on the support plate 10.

[0078] Furthermore, since the tilting rod 23 is disposed at the lower part of the support plate 10, in order to facilitate the unmanned device to press the pressing portion 22 at one end of the tilting rod 23 when it is parked on the support plate 10, when the linkage mechanism 20 is in the standby position, the pressing portion 22 may at least partially protrude from the surface of the support plate 10 through the trigger hole 14, or a component such as a bump protruding from the surface of the unmanned device and used to press the pressing portion 22 may be disposed at a position corresponding to the trigger hole 14 when the unmanned device is in the parked state; and when the linkage mechanism 20 is in the standby position, the linkage portion 21 and the charger 30 may be hidden in the lower part of the support plate 10, or at least partially protrude from the support plate 10 through the charging hole 13. The pressing part 22 is triggered by the pressing after the unmanned equipment is positioned and parked, causing the tilting rod 23 to swing around its own rotation axis, the pressing part 22 to drop, and the linkage part 21 to rise, thereby driving the charger 30 to approach the unmanned equipment in the parked state, so that the linkage mechanism 20 is in the charging position, and then the charger 30 is electrically connected to the power supply 67 of the unmanned equipment to charge it. When the unmanned equipment needs to leave the unmanned equipment parking platform and leave the support plate 10, the unmanned equipment is separated from the pressing part 22, so that the pressing part 22 loses the external force applied by the unmanned equipment. Since the linkage part 21 is provided with the charger 30, the linkage part 21 will drop under the influence of its weight, and the tilting rod 23 will swing around its own rotation axis, causing the pressing part 22 to rise and tilt, restore to the initial state, and wait for the next parking and charging of the unmanned equipment.

[0079] It should be noted here that, in order for the tilting rod 23 to smoothly return to the standby position when the unmanned equipment leaves the support plate 10, the rotating shaft between the tilting rod 23 and the support plate 10 should be arranged close to the pressing portion 22, and the force arm at one end close to the linkage portion 21 should be greater than the force arm at the other end close to the pressing portion 22. In this way, in the absence of external force, the linkage portion 21 will use the rotation axis position of the tilting rod 23 as a fulcrum to continuously apply a force on the tilting rod 23 in the direction of the standby position.

[0080] Further description, the lever mechanism also includes a mounting seat 24, the mounting seat 24 is used to provide a fulcrum for the tilting rod 23 at the bottom of the support plate 10, the mounting seat 24 is installed on the support plate 10, the mounting seat 24 and the support plate 10 are preferably detachably connected, or can be fixedly connected, and the other side of the mounting seat 24 extends away from the support plate 10. A pivot portion 241 is extended. In this embodiment, the pivot portion 241 is formed by two pivot plates 2411 of plate-like structures that are relatively spaced apart, and both pivot plates 2411 are opened. Relative pivot holes are provided, and the tilting rod 23 adopts a sheet metal structure. The opposite sides of the tilting rod 23 are bent in the same direction to form folded plates 231. The spacing between the two folded plates 231 is greater than the spacing between the two pivot plates 2411, and through holes corresponding to the pivot holes are respectively penetrated on the two folded plates 231. In this way, the two folded plates 231 can be sleeved on the outer sides of the two pivot plates 2411, and are movably connected to the through holes and the pivot holes through the rotating shaft to form the swing axis of the tilting rod 23, so that the mounting seat 24 forms the fulcrum of the tilting rod 23.

[0081] In the present embodiment, in order to allow the UAV 60 to abut against the pressing portion 22 when parked in place, the tilting rod 23 is located at one end of the pressing portion 22 and is bent toward the support plate 10, and a pressing head 232 is provided at its end for the bottom of the UAV 60 to abut against. The pressing head 232 extends out of the surface of the support plate 10 from the trigger hole 14 when the linkage mechanism 20 is in the standby position.

[0082] As another embodiment of this embodiment, the linkage mechanism 20 can also use an electric control structure (not shown) to realize the movement of the charger 30. In this embodiment, the linkage mechanism 20 includes a switch and an actuator arranged on the support plate 10. Of course, when the charging hole 13 is arranged on the guide part 12, the switch can also be arranged at a position corresponding to the guide part 12 and the charging hole 13. The switch is electrically connected to the actuator, and the switch is arranged at a position corresponding to the trigger hole 14 to form a pressing part 22. The actuator includes a fixed end and an output end. The fixed end is fixedly installed on the support plate 10, and its output end is arranged opposite to the charging hole 13 to form a linkage part 21.

[0083] When a device to be charged is parked in the charging area 11, the switch is connected to the actuator so that the charger 30 is electrically connected to the device to be charged through the drive of the actuator; when the device to be charged is not parked in the charging area 11, the switch is disconnected from the actuator so that the actuator and the charger 30 return to their initial state.

[0084] The actuator described in the above embodiment can be realized by a driving mechanism of an electromagnet cooperating with a spring reset. When in the standby state, the electromagnet is in a normally closed state, and the magnetic driving end of the electromagnet is connected to the charger 30 and is retracted into the charging hole 13. When the switch is triggered, the actuator loses power, and the spring can push its driving end together with the charger 30 out of the charging hole 13.

[0085] The actuator described in the above embodiment can also be implemented by driving components such as air cylinders and oil cylinders. A relay can be set between the actuator and the switch. The relay can be a normally open or normally closed relay. In the standby state, the relay drives the piston rod of the actuator to be retracted into the charging hole 13. When the switch is triggered, the relay causes the piston rod of the actuator to move in the direction of extending out of the charging hole 13 by conducting or disconnecting, thereby reaching the charging position.

[0086] As other implementations of this embodiment, the linkage mechanism 20 can also adopt a connected cylinder structure (not shown) to realize the movement of driving the charger 30. Specifically, the linkage mechanism 20 includes a first cylinder and a second cylinder, and the cylinder barrels of the first cylinder and the second cylinder are connected to each other. Specifically, the piston rods in the first cylinder and the second cylinder respectively divide the corresponding cylinders into a first cylinder cavity close to the side where the piston rod extends and a second cylinder cavity away from the side where the piston rod extends. The second cylinder cavity of the first cylinder is connected to the second cylinder cavity of the second cylinder. In this way, when the piston rod of the first cylinder is retracted into the cylinder body, the air in its second cylinder cavity will be squeezed into the second cylinder cavity of the second cylinder, thereby pushing the piston rod of the second cylinder out of the second cylinder. Similarly, when the piston rod of the second cylinder is retracted into the cylinder body, the piston rod of the first cylinder will also be pushed out of the first cylinder.

[0087] Continuing from the above, the first cylinder is arranged at the lower part of the support plate 10, and its piston rod is arranged opposite to the trigger hole 14 to form a pressing portion 22. The second cylinder is arranged at the lower part of the support plate 10 or the guide portion 12, and its piston rod is arranged opposite to the charging hole 13 to form a linkage portion 21. Similarly, whether the second cylinder is arranged on the support plate 10 or the guide portion 12 depends on whether the charging hole 13 is arranged on the support plate 10 or the guide portion 12. In order to allow the linkage mechanism 20 to be reset to the standby position after the unmanned equipment leaves the unmanned equipment parking platform when it is in the charging position, a first elastic reset member is provided between the cylinder barrel of the second cylinder and its piston rod. According to the above description, the first elastic reset member is sleeved on the piston rod of the second cylinder and placed in the first cylinder chamber of the second cylinder. In this way, when the second cylinder chamber of the second cylinder is inflated and its piston rod moves in the direction of extending out of the second cylinder, the piston rod will continue to be subjected to the elastic force applied by the first elastic reset member to move in the direction of the second cylinder chamber. When the piston rod of the first cylinder loses the external force, the elastic reset member will drive the piston rod of the second cylinder to reset, so that the piston rod of the first cylinder can extend out of the first cylinder again. When the linkage mechanism 20 is in the charging position, the device to be charged applies a certain force to the piston rod of the first cylinder to retract the piston rod of the first cylinder, drive the piston rod of the second cylinder to extend from its cylinder barrel and drive the charger 30 to be electrically connected to the device to be charged; when the linkage mechanism 20 is in the standby position, the first elastic reset member drives the piston rod of the second cylinder to retract, thereby driving the charger 30 to separate from the device to be charged, so that the piston rod of the first cylinder can be extended from its cylinder barrel again.

[0088] The linkage mechanism 20 described above, in addition to being able to be connected to the support plate 10, can also be set at any position in the installation cavity 51 through other support parts 61 or connecting parts, and can be connected to other parts of the base 50, as long as its function can achieve the above-mentioned linkage to enable the charger 30 to reciprocate between the charging position or the standby position.

[0089] In order to make the charger 30 move more stably between the charging position and the standby position and ensure the transmission connection between the linkage mechanism 20 and the charger 30 is effective, the present embodiment further includes a support seat 40, which is used to cooperate with the charger 30, can protect the charger 30, reduce the probability of contact with the outside in the standby position, and can also help limit the direction of movement of the charger 30 between the standby position and the charging position. Specifically, the support seat 40 is arranged on the support plate 10, and the support seat 40 can be arranged at the bottom of the support plate 10 or at the upper part of the support plate 10. In the present embodiment, the size of the charging hole 13 on the support plate 10 matches the size of the support seat 40, a positioning platform is arranged on the support plate 10, and a positioning structure matching the positioning platform is arranged on the outside of the support seat 40, the support seat 40 is partially embedded in the charging hole 13, and partially protrudes from the charging hole 13 to the surface of the support plate 10, and the support plate 10 and the support seat 40 cooperate through the positioning platform and the positioning structure so that the support seat 40 can be stuck in the charging hole 13.

[0090] The support base 40 has a hollow portion to form an activity space 41 . The support base 40 has an upper side formed with a first activity opening 42 connected to the activity space 41 . The charger 30 is disposed in the activity space 41 . The charger 30 can extend out of the support base 40 from the first activity opening 42 .

[0091] When the linkage mechanism 20 is in the charging position, the charger 30 will extend out of the support seat 40 from the first movable opening 42, so that the charger 30 can be closer to the unmanned equipment; in the horizontal direction of the support plate 10, the horizontal height of the charger 30 in the charging position is greater than the horizontal height of the charger 30 in the standby position. When the linkage mechanism 20 is in the standby position, the charger 30 can be hidden in the active space 41, or it can at least partially protrude from the surface of the support seat 40 from the first movable opening 42. In this embodiment, the charger 30 is a contact charger 30, specifically a charging terminal, and therefore, it has a certain length. In order to reduce the volume of the support seat 40, the charger 30 of this embodiment partially protrudes from the surface of the charging seat in the standby position.

[0092] Of course, the contact charger 30 can also be a wireless charging plate, and the charger 30 can also be a non-contact charger 30. Both the contact and non-contact chargers 30 use the existing charger 30 structure in the charger 30 field as an illustration of this embodiment, and its specific structure will not be described in detail here.

[0093] Furthermore, a second movable port 43 connected to the movable space 41 is also opened on the lower side of the support base 40, and the first movable port 42 and the second movable port 43 are arranged opposite to each other. The charger 30 can reciprocate between the first movable port 42 and the second movable port 43. When the linkage mechanism 20 is in the standby position, the charger 30 is located in the movable space 41 near the second movable port 43.

[0094] Specifically, the linkage part 21 of the linkage mechanism 20 is located at the lower part of the support base 40. When the linkage mechanism 20 is in the charging position, the linkage part 21 is close to the second active port 43 to abut against the charger 30 and drive the charger 30 to move toward the first active port 42. When the linkage mechanism 20 is in the standby position, the linkage part 21 is away from the second active port 43 to move the charger 30 toward the second active port 43 to reset.

[0095] In order to make the movement of the charger 30 more stable, this embodiment provides two guiding structures for guiding the movement of the charger 30:

[0096] like Fig.10 The figure shows a cross-sectional assembly diagram of the structure 1. In this embodiment, the support seat 40 is a shell structure, and the internal movable space 41 is a cavity structure for protecting the internal charger structure. A guide cylinder 44 is also provided on the outside of the support seat 40. In this embodiment, the guide cylinder 44 is provided at the bottom of the support seat 40 and adjacent to the second movable opening 43. The extension direction of the guide cylinder 44 is substantially the same as the movement direction of the charger 30. One end of the guide cylinder 44 is connected to the movable space 41 through a guide hole 441.

[0097] A guide assembly is disposed in the activity space 41 and the guide cylinder 44 . The guide assembly is connected to the charger 30 and is used to limit the direction in which the charger 30 moves between the charging position and the standby position.

[0098] Specifically, the guide assembly includes a guide plate 45, which is flatly arranged in the movable space 41, and the edge of the guide plate 45 is matched with the inner wall gap of the movable wall, so that it can be movably arranged in the movable space 41, and the charger 30 is fixed to the side surface of the guide plate 45 facing the first movable port 42, and the other side surface of the guide plate 45 faces the second movable port 43 and forms a convex portion for the linkage mechanism 20 to press against. In this way, when the linkage mechanism 20 presses against the convex portion, the guide plate 45 can move toward the first movable port 42 together with the charger 30.

[0099] A guide column 46 is movably arranged in the guide cylinder 44, and the diameter of the guide column 46 is smaller than the guide hole 441, so that it can be fixedly connected to the guide plate 45 through the guide hole 441. In this embodiment, a threaded section is arranged at the end of the guide column 46, and correspondingly, a threaded hole is through-arranged on the guide plate 45, so that the guide column 46 can be threadedly connected to the guide plate 45, and a limit plate 461 with a diameter larger than the guide hole 441 is arranged at the end of the guide column 46 away from the guide hole 441. The guide column 46 can move along the length direction of the guide cylinder 44 to reciprocate in the direction of extending into the active space 41 and retracting the guide cylinder 44. The limit plate 461 and the guide plate 45 can respectively constrain the axial movement stroke of the guide column 46 to prevent the guide column 46 from fully extending into the active space 41 or fully retreating into the guide cylinder 44, and being disconnected from the support seat 40.

[0100] Furthermore, in order to allow the guide assembly to reset or remain in the initial state after pushing the charger 30 out of the first movable opening 42 without the application of external force, the guide assembly also includes a second elastic reset member 47, which has a diameter larger than the guide hole 441 and is arranged in the guide cylinder 44 between the support seat 40 and the limit plate 461 to continuously apply an elastic force to the guide column 46 to drive the guide plate 45 to move toward the standby position.

[0101] In this embodiment, there are two guide cylinders 44, which are relatively arranged on both sides of the second movable opening 43. Correspondingly, there are two guide columns 46 and second elastic return members 47, which are respectively arranged in the corresponding guide cylinders 44. The two guide columns 46 are respectively fixedly connected to the two ends of the guide plate 45.

[0102] like Figure 11-Figure 12The figure shows an assembly diagram of the second structure. In this embodiment, the support seat 40 is a plate structure. The charger 30 is protected by a shell that can reciprocate in the activity space 41, and the shell and the charger 30 are integrated. A guide rail 48 is provided at the lower part of the support seat 40. The extension direction of the guide rail 48 is consistent with the movement direction of the charger 30. Specifically, the guide rail 48 extends in a direction perpendicular to the horizontal plane. Accordingly, the charger 30 is provided with a slider 49 that slides with the guide rail 48. In order to stably fix the slider 49 on the charger 30, an adapter 32 is provided at the lower part of the shell on the charger 30. The adapter 32 extends in a direction perpendicular to the horizontal plane, and the slider 49 is provided on the adapter 32 along the extension direction of the adapter 32. In order for the slider 49 to guide the charger 30, the length of the guide rail 48 is greater than the slider 49, so that when the slider 49 slides along the extension direction of the guide rail 48, it drives the charger 30 to reciprocate between the charging position and the standby position. The linkage part 21 contacts the bottom of the charger 30 . When the linkage part 21 is lifted upward, the linkage part 21 swings around the pivot part 241 , so the linkage part 21 and the bottom of the charger 30 slide relative to each other and drive the charger 30 to be lifted.

[0103] Further, in order to facilitate the charger 30 to be reset to the standby position in the charging position, a third elastic reset member 31 is provided between the adapter 32 and the guide rail 48 as a whole, which is connected to the housing of the charger 30. In this embodiment, the third elastic reset member 31 is a tension spring. Specifically, the third elastic reset member 31 One end is connected to the end of the guide rail 48 away from the support seat 40, and the other end of the third elastic reset member 31 is connected to the end of the adapter 32 away from the support seat 40. In this way, when the charger 30 moves from the standby position to the charging position, the adapter 32 will move toward the first active port 42 together with the charger 30, and at the same time pull the third elastic reset member 31. At this time, the third elastic reset member 31 will continue to apply an elastic force to the charger 30 to move in the direction of the standby position. When the unmanned aerial vehicle 60 leaves the support plate 10 and the tilting rod 23 loses the pressure of the unmanned aerial vehicle 60, the pressing part 22 loses the pressure, so that the third elastic reset member 31 can pull the charger 30 to move in the direction of the standby position and reset, so that the pressing part 22 rises again and returns to the standby position.

[0104] The following is a specific implementation of the guide portion 12, as one of the structures of the guide portion 12, in this solution, the number of the guide portions 12 is preferably consistent with the number of the support portions 61 of the unmanned equipment, the guide portion 12 is recessed in the support plate 10, the guide portion 12 includes a guide opening connected to the surface of the support plate 10, a support surface located at the bottom of the guide portion 12 to support the device to be charged, and the guide opening and the support surface are connected to form a guide surface. The guide surface gradually narrows from one end of the guide opening toward the support surface, so that the guide portion 12 forms an inverted cone or bowl-shaped structure.

[0105] In this embodiment, when the tripod 65 of the unmanned aerial vehicle 60 serving as the support portion 61 lands on the guide portion 12, the tripod 65 will slide along the side wall of the guide portion 12 to the bottom of the guide portion 12. If the trigger hole 14 is provided on the support plate 10, the fuselage 63 of the unmanned aerial vehicle 60 will come into contact with the pressing portion 22, driving the linkage portion 21 to drive the charger 30 to approach the unmanned aerial vehicle 60 and be electrically connected to its power source 67. If the trigger hole 14 is provided at the bottom of the guide portion 12, when the tripod 65 of the unmanned aerial vehicle 60 slides to the bottom of the guide portion 12, the support portion 61 thereof will come into contact with the pressing portion 22, thereby completing the charging of the unmanned aerial vehicle 60 through the linkage mechanism 20.

[0106] As another structure of the guide portion 12, the guide portion 12 includes a guide surface disposed facing the charging area 11, and a plurality of guide surfaces are disposed around the periphery of the charging area 11, so that the charging area 11 and the plurality of guide surfaces are combined to form a groove-shaped structure. When the unmanned aerial vehicle 60 needs to land on the unmanned equipment parking platform, the remote control device sends the location information of the unmanned equipment parking platform to the unmanned aerial vehicle 60, so as to enable the unmanned aerial vehicle 60 to fly above the unmanned equipment parking platform according to the location information, and land on the guide portion 12, slide along the guide surface of the guide portion 12 to the charging area 11, complete the positioning, and then complete the charging of the unmanned aerial vehicle 60 through the above process.

[0107] Through the above-mentioned implementation mode, the guide part 12 can cooperate with the linkage mechanism 20, so that after the unmanned equipment is guided and positioned to complete parking, the linkage mechanism 20 drives the charger 30 to charge the unmanned equipment, thereby reducing the parking positioning accuracy of the unmanned equipment, making the parking process of the unmanned equipment shorter, and thus improving the charging efficiency of the unmanned equipment.
