Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to a contact-type automatic charging device for UAVs using a coupling insertion method. Background Technology

[0002] Unmanned aerial vehicles (UAVs) are unmanned aircraft controlled by radio remote control equipment and onboard program control devices. They can take off and land vertically and fly flexibly. With capabilities such as high-definition photography, precise positioning, and efficient operation, they are widely used in aerial photography, surveying and mapping, agricultural plant protection, logistics and distribution, and emergency rescue, continuously expanding the boundaries and efficiency of human activities.

[0003] Drones are typically powered by batteries and therefore require frequent charging. A search revealed a contact-type automatic charging device for drones disclosed in CN205811623U, which includes a charging base and a charging plate. Although the device is simple in structure, it lacks the ability to secure the drone during charging. The drone is prone to movement under external forces, affecting charging or causing poor contact. Therefore, a contact-type automatic charging device for drones using a coupling insertion method is proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the lack of fixation for the drone during charging, which makes the drone prone to movement under external forces, affecting charging or causing poor contact. Therefore, this invention proposes a contact-type automatic charging device for drones that uses a coupling insertion method.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A contact-type automatic charging device for drones using a coupling insertion method includes a drone body and a charging shell. The top of the charging shell is fixedly connected to four through-hole positioning and fixing sleeves, the top of which is flared. The bottom of the drone body is fixed with four support columns corresponding to the positioning and fixing sleeves, the bottom of which is conical.

[0007] Each of the support columns has a through-hole plug-in connection hole on one side. The top inner wall of the charging shell is provided with four fasteners for fixing the support columns. Each fastener includes a guide sleeve, which is fixed to the top inner wall of the charging shell. A through-hole plug-in connection rod is slidably connected to one side of the guide sleeve. The end of the plug-in connection rod near its corresponding plug-in connection hole is triangular.

[0008] A charging mechanism, which is disposed inside the charging shell, is used to charge the drone body.

[0009] A drive mechanism, which is disposed inside the charging housing, is used to drive the plug-in connecting rod to move so that the drone body remains stable when charging.

[0010] As a further embodiment of this utility model, the driving mechanism includes a mounting base plate, which is fixed to the inner wall of the charging shell. An electric push rod is fixedly connected to the surface of the mounting base plate, and an upper load-bearing cover plate is fixedly connected to the output end of the electric push rod. Both ends of the upper load-bearing cover plate are rotatably connected to four plug-in connecting rods by diagonal braces.

[0011] As a further embodiment of this utility model, the charging mechanism includes two mounting boxes, two contact pieces I, two female connectors, and two male connectors. The two mounting boxes are respectively fixed to the inner walls of both sides of the bottom of the drone body. Contact pieces II are fixedly connected to the top inner wall of each mounting box. Contact pieces I are fixed to the top of the charging shell and abut against contact pieces II when the drone body falls. The female connectors are fixed to the top inner wall of the charging shell and are electrically connected to contact pieces I. The male connectors are fixed to one side of the upper load-bearing cover and are inserted into the female connectors when the upper load-bearing cover rises.

[0012] As a further embodiment of this utility model, the top of the charging shell is provided with an installation port, and a heat dissipation fan is fixedly connected inside the installation port. The circumference of the charging shell is provided with multiple air inlet holes.

[0013] As a further improvement of this invention, a counterweight base is fixedly connected to the bottom of the charging case.

[0014] As a further improvement of this invention, a rubber pad is adhered to the bottom of the counterweight base.

[0015] As a further improvement of this invention, a top cover is placed on the top of the charging case.

[0016] As a further improvement of this utility model, a control board is fixed inside the charging shell.

[0017] In this application, during use, the drone body lands on the charging shell, and the support column is inserted into the positioning and fixing sleeve to complete the landing process. After landing, contact piece I and contact piece II contact each other to form a circuit. During charging, the electric push rod is activated, which drives the upper load-bearing cover plate to rise. The upper load-bearing cover plate first pushes the plug-in connecting rod to move through the diagonal brace. The plug-in connecting rod is inserted into the plug-in connecting hole, thereby fixing the drone body and preventing movement during charging. Subsequently, the upper load-bearing cover plate drives the male connector to be inserted into the female connector, thereby completing the circuit connection and charging the drone body. During charging, the cooling fan can be activated to dissipate heat from the inside of the charging shell, preventing overheating and improving the service life.

[0018] Beneficial effects: In this utility model, the contact-type automatic charging device for drones using a coupling insertion method fixes the drone body, thereby maintaining its stability during charging and preventing it from tipping over and losing power during charging.

[0019] In this utility model, the contact-type automatic charging device for drones using a coupling insertion method, through the setting of a cooling fan and an air inlet, allows the cooling fan to be activated during charging, thereby dissipating heat from the inside of the charging shell, preventing overheating of the charging shell and improving its service life.

[0020] In this invention, the drone body can be fixed during charging to maintain its stability and prevent it from tipping over and losing power. At the same time, the cooling fan can be activated to dissipate heat from the inside of the charging shell, preventing overheating and improving its service life. Attached Figure Description

The end of the plug-in connection rod 20 near the corresponding plug-in connection hole 21 is triangular.

[0030] A charging mechanism is installed inside the charging shell 1 to charge the drone body 6.

[0031] The drive mechanism, which is located inside the charging housing 1, is used to drive the plug-in connecting rod 20 to move so that the drone body 6 remains stable when charging.

[0032] This application can be used in the field of unmanned aerial vehicles (UAVs) or in other fields applicable to this application.

[0033] In another embodiment: Reference Figures 1-5 A contact-type automatic charging device for drones using a coupling insertion method is applied to the field of drones.

The two ends of the upper load-bearing cover plate 10 are rotatably connected to four plug-in connecting rods 20 by diagonal braces 18. When the electric push rod 9 is activated, the electric push rod 9 drives the upper load-bearing cover plate 10 to rise. The upper load-bearing cover plate 10 first pushes the plug-in connecting rods 20 to move through the diagonal braces 18. The plug-in connecting rods 20 are inserted into the plug-in connecting holes 21, thereby fixing the drone body 6.

[0035] Specifically, the charging mechanism includes two mounting boxes 14, two contact pieces I 13, two female connectors 11, and two male connectors 12.
