Description

Technical Field

[0001] This utility model belongs to the field of drones, and specifically relates to a drone charging structure. Background Technology

[0002] Currently, drone technology is undergoing rapid changes. Due to their flexibility, maneuverability, and ability to perform long-range, high-altitude operations, drones can be applied to various fields. The application of drones, based on remote-controlled flight, can be designed according to specific application scenarios.

[0003] Drones operating over long distances typically require a charging bay. Some charging bays can be mounted on vehicles, allowing the drone to be parked and charged when not in use. How to automatically and efficiently perform charging and battery swapping operations within a vehicle-mounted charging bay is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] To address the problems and shortcomings of existing technologies, the purpose of this utility model is to provide a drone charging structure that can efficiently complete charging and battery swapping operations within a relatively small space.

[0005] A drone charging structure includes an upper push-pull rail, a lower push-pull rail, a charging module frame, a charging plug, and a stepper motor. The upper and lower push-pull rails are arranged in parallel, the charging module frame is positioned between the upper and lower push-pull rails, and the charging plug is positioned inside the charging module frame. The stepper motor is connected to the upper and lower push-pull rails and can drive the upper and lower push-pull rails to translate. The surfaces of both the upper and lower push-pull rails are provided with inclined groove structures. The charging plug has insertion interfaces on both the left and right sides, and both the upper and lower ends of the charging plug have protrusions that cooperate with the inclined groove structures. When the upper and lower push-pull rails translate, the charging plug translates vertically within the charging module frame along the upper and lower push-pull rails.

[0006] Furthermore, a connecting block is provided at one end of the upper push-pull guide rail and the lower push-pull guide rail. The connecting block is used to connect and fix the upper push-pull guide rail and the lower push-pull guide rail. A lead screw is provided between the connecting block and the stepper motor. One end of the lead screw is connected to the connecting block, and the other end is connected to the stepper motor through a coupling.

[0007] Furthermore, there are two charging plugs, each with two protruding posts on one side. The upper and lower push-pull guide rails are each provided with two sets of inclined groove structures, each set of inclined groove structures containing two inclined groove holes.

[0008] Furthermore, a double-headed hexagonal stud is provided between the middle of the upper and lower push-pull guide rails, and threaded holes are provided in the middle of both the upper and lower push-pull guide rails.

[0009] Furthermore, the inclined slot hole is a rhomboid hole, and the protrusion is a rhomboid protrusion.

[0010] Furthermore, the upper part of the connecting block is provided with a lead screw connection hole, the middle part of the connecting block is provided with an upper mounting hole for connecting and installing the upper push-pull guide rail, and the lower part of the connecting block is provided with a lower mounting hole for connecting and installing the lower push-pull guide rail. The upper push-pull guide rail and the lower push-pull guide rail are both connected to the connecting block by bolts.

[0011] The advantages of this utility model are:

[0012] 1. The lead screw is driven by a stepper motor to rotate, and then the lead screw drives the upper and lower push-pull guide rails to move horizontally, which in turn drives the extension and retraction of the charging plug. The overall structure is compact and occupies little space. The plug insertion and removal are efficient and safe, making it suitable for use in vehicle charging compartments to realize the plug insertion and removal action.

[0013] 2. This structure can be equipped with multiple charging plugs at the same time. When used with a battery transport platform, it can charge multiple batteries simultaneously, which can meet the power needs of drones used on vehicles. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] A drone charging structure includes an upper push-pull rail, a lower push-pull rail, a charging module frame, a charging plug, and a stepper motor. The upper and lower push-pull rails are arranged parallel to each other. The charging module frame is positioned between the upper and lower push-pull rails, and the charging plug is located inside the charging module frame. The stepper motor is connected to the upper and lower push-pull rails and can drive the upper and lower push-pull rails to translate. Both the upper and lower push-pull rails have inclined groove structures on their surfaces. The charging plug has insertion interfaces on both sides, and protrusions at both ends of the charging plug that cooperate with the inclined groove structures. When the upper and lower push-pull rails translate, the charging plug translates vertically within the charging module frame along the upper and lower push-pull rails. A connecting block is also provided at one end of the upper and lower push-pull rails for connecting and fixing the upper and lower push-pull rails. A lead screw is provided between the connecting block and the stepper motor. One end of the lead screw is connected to the connecting block, and the other end is connected to the stepper motor via a coupling. There are two charging plugs, each with two protruding posts on one side. The upper and lower push-pull guide rails each have two sets of inclined groove structures, each containing two inclined groove holes. A double-headed hexagonal stud is located between the middle of the upper and lower push-pull guide rails, and threaded holes are located in the middle of both rails. The inclined groove holes and protruding posts are diamond-shaped. The connecting block has a lead screw connection hole at the top, an upper mounting hole for connecting and installing the upper push-pull guide rail in the middle, and a lower mounting hole for connecting and installing the lower push-pull guide rail at the bottom. Both the upper and lower push-pull guide rails are connected to the connecting block via bolts.

[0022] The practical application method is as follows:

[0023] Typically, this drone charging structure is used in conjunction with a battery carrier and a power control module. A fully charged battery is removed via the carrier, and batteries awaiting charging are transported to the charging station via the carrier. The power control module controls the on / off state of the charging socket.

[0024] When the battery is in the charging station, the stepper motor runs, driving the upper and lower push-pull rails to move horizontally. Since the charging plug is connected to the upper and lower push-pull rails through a groove and a protrusion, when the upper and lower push-pull rails move horizontally, the charging plug will move vertically within the outer frame of the charging module along the upper and lower push-pull rails. This horizontal movement is the action of connecting the charging plug to the battery pins.

[0025] The disconnection action after charging is completed is the reverse of the plugging action.

[0026] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
