Description

Technical Field

[0001] This invention belongs to the field of unmanned aerial vehicle (UAV) airport technology, specifically relating to a guide rail transmission module, a transmission mechanism, an UAV airport door, and a method of using them. Background Technology

[0002] The statements in this section are merely background information related to the present invention and do not necessarily constitute prior art.

[0003] Unmanned aerial vehicle (UAV) airport products are gradually being widely used in power line inspection operations. These airports are typically deployed outdoors in complex environments. As electrical equipment, airports have stringent requirements for water and dust protection, needing to meet an IP55 protection rating. In extreme icy or snowy weather, the drone airport's hatch shell may be covered in ice and snow, or even frozen shut. If foreign objects encounter the hatch shell during closing, it can cause mechanical damage, severely impacting normal operation.

[0004] The opening and closing of the hatch shell corresponds to the launch and recovery of the drone. As the main moving mechanism of the airport, the details of its operation play a crucial role in the overall protection of the drone airport.

[0005] Currently, there are many manufacturers producing drone airports, and there are many types of airport opening methods, such as flip-top, drawer, and sliding types, which cannot achieve multi-directional opening. At the same time, they cannot be used normally in extreme weather conditions, such as when the door shell is frozen and cannot be opened in extremely cold weather. When the drone's landing point deviates, the door shell may damage the drone during the closing process. This will seriously affect the stability of the drone's structure and may even endanger the personal safety of drone debugging personnel, posing a significant safety hazard. Summary of the Invention

[0006] To address the aforementioned issues, this invention proposes a guide rail transmission module, a transmission mechanism, an unmanned aerial vehicle (UAV) airport door, and a method for using them. The addition of a guide rail transmission module, with its arc-shaped structure of fixed and driven arc-shaped guide rail modules, enhances the flexibility of the guide rail transmission. The transmission mechanism enables the door shell to move vertically and horizontally, improving the effective sealing of the door shell and meeting the IP protection level requirements of airports. Simultaneously, a heating mechanism is added to prevent icing, and a detection mechanism is added to prevent compression and foreign objects from obstructing the door.

[0007] According to some embodiments, the first aspect of the present invention provides a guide rail transmission module, which adopts the following technical solution:

[0008] A guide rail transmission module includes a fixed arc-shaped guide rail module, a driven arc-shaped guide rail module, an active pulley module, a driven pulley module, a support pulley module, and a steering module. The fixed arc-shaped guide rail module and the steering module are connected via a third coupling. The support pulley module is mounted on the steering module. The active pulley module moves on the fixed arc-shaped guide rail module via a lead screw. The driven pulley module is connected to the active pulley module. The driven arc-shaped guide rail module is fixedly connected to the driven pulley module. The support pulley module is fixedly connected to the driven arc-shaped guide rail module.

[0009] As a further technical limitation, the active pulley module drives the driven pulley module to move within the fixed arc-shaped guide rail module. When the active pulley module drives the driven pulley module to pass through the arc-shaped position of the track, the driven pulley module achieves up and down movement through the arc-shaped trajectory.

[0010] The arc-shaped trajectory at the end of the driven arc-shaped guide rail module is the same as that at the end of the fixed arc-shaped guide rail module. When the driven pulley module moves along the arc-shaped trajectory, it drives the driven arc-shaped guide rail module to move.

[0011] According to some embodiments, a second aspect of the present invention provides a transmission mechanism that employs the guide rail transmission module as provided in the first aspect, and adopts the following technical solution:

[0012] A transmission mechanism includes a main drive shaft assembly and guide rail transmission modules respectively disposed at both ends of the main drive shaft assembly.

[0013] As a further technical limitation, the main drive shaft assembly is connected to the guide rail transmission modules disposed at both ends of the main drive shaft assembly via a first coupling group; the first coupling group includes a first coupling and a second coupling respectively disposed on the two guide rail transmission modules; the first coupling and the second coupling are connected by a drive shaft.

[0015] According to some embodiments, a third aspect of the present invention provides a drone airport door, which employs the transmission mechanism provided in the second aspect, and adopts the following technical solution:

[0016] A drone airport door, characterized in that it employs a door assembly; the door assembly includes a door shell and a heating mechanism for preventing icing and a detection mechanism for monitoring foreign objects and door shell pressure, both disposed on the door shell; a transmission mechanism is connected to the inner side of the door shell.

[0017] As a further technical limitation, it also includes a drone airport body that matches the door shell; a rain and snow sensor is provided on the outer side of the drone airport body; a control mechanism connected to the rain and snow sensor, heating mechanism and detection mechanism is provided on the inner side of the drone airport body; a sheet metal flange is provided on the opening side frame of the drone airport body, and a sealing strip is provided on the outer side of the flange.

[0018] Furthermore, the heating mechanism is used to prevent the hatch from icing, and includes a heating wire pad, a heat insulation layer, a heat insulation layer press sheet, and an external temperature sensor; the detection mechanism is used to monitor the hatch pressure and whether there are foreign objects between the hatch and the UAV airport body, and includes a pressure contact film and an infrared grating.

[0019] According to some embodiments, the fourth aspect of the present invention provides a method for using a drone airport door, which adopts the drone airport door provided in the third aspect, and employs the following technical solution:

[0020] A method for using a drone airport door involves a main drive shaft assembly driving a first guide rail drive module and a second guide rail drive module to move under the action of a motor, thereby enabling the door assembly to run on the drone airport body.

[0021] As a further technical limitation, when the hatch shell changes from open to closed, the main drive shaft assembly provides power. The active pulley module in the first guide rail transmission module moves in translation on the fixed arc-shaped guide rail module through the screw drive, driving the driven pulley module to move within the fixed arc-shaped guide rail module. The driven arc-shaped guide rail module moves synchronously under the support of the supporting pulley module and the drive of the driven pulley module. The action of the second guide rail transmission module is consistent with that of the first guide rail transmission module. The first and second guide rail transmission modules drive the hatch assembly to move. The active pulley module drives the driven pulley module to enter the end of the arc-shaped track. The driven pulley module moves through the arc-shaped trajectory, thereby driving the driven arc-shaped guide rail module and the hatch assembly to move until the hatch shell presses against the sealing strip of the UAV airport body, completing the entire hatch closing action.

[0022] As a further technical limitation, when the hatch shell changes from open to closed, the main drive shaft assembly provides power. The active pulley module in the first guide rail transmission module moves in translation on the fixed arc-shaped guide rail module through the screw drive, driving the driven pulley module to move within the fixed arc-shaped guide rail module. The driven arc-shaped guide rail module moves synchronously under the support of the supporting pulley module and the drive of the driven pulley module. The action of the second guide rail transmission module is consistent with that of the first guide rail transmission module. The first and second guide rail transmission modules drive the hatch assembly to move. The active pulley module drives the driven pulley module to enter the end of the arc-shaped track. The driven pulley module moves through the arc-shaped trajectory, thereby driving the driven arc-shaped guide rail module and the hatch assembly to move until the hatch shell presses against the sealing strip of the UAV airport body, completing the entire hatch closing action.

[0049] Example 1

[0050] Embodiment 1 of the present invention introduces a guide rail transmission module.

[0051] like Figure 1 The guide rail transmission module shown includes a fixed arc-shaped guide rail module 301, a driven arc-shaped guide rail module 302, an active pulley module 303, a driven pulley module 304, a support pulley module 305, and a steering module 306.

[0052] The fixed arc-shaped guide rail module 301 is connected to the steering gear module 306 via a third coupling 307, and the support pulley module 305 is mounted above the steering gear module 306. The active pulley module 303 moves back and forth on the fixed arc-shaped guide rail module 301 via a lead screw 308. The driven pulley module 304 is connected to the active pulley module 303, and the active pulley module 303 drives the driven pulley module 304 to move within the fixed arc-shaped guide rail module 301. When the active pulley module 303 drives the driven pulley module 304 through the arc-shaped position of the track, the driven pulley module 304 moves up and down along the arc-shaped trajectory. The driven arc-shaped guide rail module 302 is connected to the driven pulley module 304 by bolts. The wheel of the supporting pulley module 305 is set in the guide rail of the driven arc-shaped guide rail module 302, providing support. The arc-shaped trajectory at the end of the driven arc-shaped guide rail module 302 is the same as the arc-shaped trajectory at the end of the fixed arc-shaped guide rail module 301. When the driven pulley module 304 moves up and down along the arc-shaped trajectory, it drives the driven arc-shaped guide rail module 302 to move up and down. The main drive shaft assembly 5 is connected to the motor via a belt, providing power to the entire device.

[0053] Understandably, in this embodiment, a first pulley is provided on the drive shaft 501, and a second pulley is provided on the output shaft of the motor; the first pulley and the second pulley are connected by a belt; when the motor is working, the output shaft of the motor drives the first pulley to rotate, the first pulley drives the second pulley to rotate via the belt, and the rotation of the second pulley drives the drive shaft 501 to rotate. In other embodiments, the main drive shaft assembly 5 may also adopt other structural configurations.

[0054] This embodiment provides a guide rail transmission module. By setting the arc structure of the fixed arc-shaped guide rail module and the driven arc-shaped guide rail module, it solves the problems of poor sealing of the hatch shell and inflexible movement of the hatch shell in the prior art, and improves the flexibility of the guide rail transmission and the sealing of the hatch shell.

[0055] Example 2

[0056] Embodiment 2 of the present invention introduces a transmission mechanism that uses the guide rail transmission module introduced in Embodiment 1.

[0057] like Figure 2 The transmission mechanism shown includes a main drive shaft assembly 5 and guide rail transmission modules respectively disposed at both ends of the main drive shaft assembly 5. In this embodiment, to distinguish the guide rail transmission modules disposed at both ends of the main drive shaft assembly 5, they are respectively referred to as the first guide rail transmission module 3 and the second guide rail transmission module 4. The first guide rail transmission module 3 and the second guide rail transmission module 4 have completely identical structural configurations and are symmetrically arranged.

[0058] This embodiment provides a transmission mechanism that, by adding a guide rail transmission module, enables the hatch shell to move up and down and translate forward and backward, solving the problem that the hatch shell cannot move in multiple directions in the prior art and improving the diversity of hatch shell movement.

[0059] Example 3

[0060] Embodiment 3 of the present invention introduces an unmanned aerial vehicle (UAV) airport door, which adopts the transmission mechanism described in Embodiment 2.

[0061] like Figure 3 As shown, the drone airport door includes the drone airport body 1 and the door assembly 2; a rain and snow sensor 102 is provided on the outer side of the drone airport body 1, a sheet metal flange is provided on the side frame of the opening, and a sealing strip 101 is provided on the outer side of the flange; a transmission mechanism is connected to the inner side of the door shell.

[0062] like Figure 4 As shown, the main drive shaft assembly 5 is connected to the first guide rail drive module 3 and the second guide rail drive module 4 respectively via the first coupling group 502. The hatch shell 201 is connected to the first guide rail drive module 3 and the second guide rail drive module 4 respectively via bolts. The first coupling group 502 includes a first coupling 5021 disposed on the first guide rail drive module 3 and a second coupling 5022 disposed on the second guide rail drive module 4. The first coupling 5021 and the second coupling 5022 are connected by the drive shaft 501.

[0063] like Figure 5 and Figure 6As shown, the hatch assembly 2 includes a hatch housing 201 and a heating wire pad 202, a heat insulation layer 203, a heat insulation layer pressing sheet 204, a pressure contact film 205, an infrared grating 206, and an external temperature sensor 207 disposed on the hatch housing 201. The heating wire pad 202 is placed against the inner wall of the hatch housing 201 on one side, and the heat insulation layer 203 is disposed on the other side of the heating wire pad 202. The heat insulation layer pressing sheet 204 is connected to the hatch housing 201 by bolts, and the heat insulation layer pressing sheet 204 presses the heating wire pad 202 and the heat insulation layer 203 tightly onto the hatch housing 201. The pressure contact film 205 is bonded to the front side of the hatch housing 201 with 3M adhesive. The infrared grating 206 and the external temperature sensor 207 are installed on the hatch housing 201 by their own bolts and nuts.

[0064] The hatch housing 201 is provided with a flange to press the sealing strip 101 for better sealing effect; the heating wire gasket 202 has an operating temperature of about 30 degrees Celsius; the pressure contact diaphragm 205 generates a sensing signal when the pressure is greater than 0.02N; the infrared grating 206 is evenly arranged at the front end of the hatch housing 201 and can emit infrared light. An infrared receiver for receiving the signal of the infrared grating 206 is provided on the UAV airport body 1 (it can be set at a matching position on the hatch housing 201 on the UAV airport body 1, not marked in the attached figure).

[0065] This embodiment of the drone airport door solves the problem in existing technologies where the door shell cannot be opened due to icing in extremely cold weather by incorporating a heating mechanism. The combination of heating wire pads, insulation layers, and insulation layer pressure plates improves the flexibility of opening and closing the door shell, freeing it from environmental constraints. Furthermore, the inclusion of a detection mechanism addresses the issue in existing technologies where the door shell damages the drone and injures personnel during closure when the drone's landing point deviates. The combination of a pressure contact film and an infrared grating further enhances the flexibility and safety of door closure, improving the stability of the drone.

[0066] Example 4

[0067] Embodiment 4 of the present invention introduces a method for using a drone airport door, which adopts the drone airport door described in Embodiment 3.

[0068] A method for using an unmanned aerial vehicle (UAV) airport door involves a main drive shaft assembly 5 driving a first guide rail drive module 3 and a second guide rail drive module 4 to move under the action of a motor, thereby enabling the door shell 201 to run on the UAV airport body 1.

[0069] like Figure 9 and Figure 10As shown, the hatch housing 201 changes from open to closed. The main drive shaft assembly 5 provides power, and the active pulley module 303 in the first guide rail transmission module 3 moves forward within the fixed arc-shaped guide rail module 301 via a screw drive, thereby driving the driven pulley module 304 forward within the fixed arc-shaped guide rail module 301. The driven arc-shaped guide rail module 302 moves forward synchronously under the support of the supporting pulley module 305 and the drive of the driven pulley module 304. At this time, the action in the second guide rail transmission module 4 is consistent with that in the first guide rail transmission module 3. The two transmission modules drive the hatch housing 201 forward. Finally, the active pulley module 303 drives the driven pulley module 304 to enter the end of the arc-shaped track. The driven pulley module 304 moves downward along the arc-shaped trajectory, thereby driving the driven arc-shaped guide rail module 302 and the hatch housing 201 downward until the hatch housing 201 effectively presses against the sealing strip 101 of the UAV airport body 1, completing the entire hatch closing action.

[0070] like Figure 7 and Figure 8 As shown, the hatch housing 201 changes from closed to open. The main drive shaft assembly 5 provides power, and the active pulley module 303 in the first guide rail transmission module 3 moves backward within the fixed arc-shaped guide rail module 301 via a screw drive. This drives the driven pulley module 304 to move upward along the arc-shaped trajectory, and in turn, drives the driven arc-shaped guide rail module 302 and the hatch housing 201 to move upward, causing the hatch housing 201 to detach from the sealing strip 101 of the UAV airport body 1, until the driven pulley module 304 completely exits the end of the arc-shaped track. Then, the driven arc-shaped guide rail module 302 moves backward synchronously under the support of the supporting pulley module 305 and the drive of the driven pulley module 304, until the hatch housing 201 is fully opened, thus completing the entire hatch opening action.

[0071] In this embodiment, as Figure 9 As shown, when the hatch housing 201 needs to be closed, the control mechanism in the UAV airport body 1 issues a closing command and starts timing. The infrared receiver receives the infrared light emitted by the infrared grating 206 in real time. When a foreign object falls into the translational path of the hatch housing 201, the foreign object will block the infrared light emitted by one or more infrared gratings 206. At this time, the corresponding infrared receiver on the UAV airport body 1 will not receive the infrared light, and the signal will be transmitted to the airport control mechanism in the UAV airport body 1. The control mechanism controls the hatch assembly 2 to stop operating and stops timing. After the foreign object is removed, the control mechanism resumes timing and controls the hatch assembly 2 to continue closing.

[0072] The control mechanism times the translational movement of the entire door assembly 2. If the door shell 201 does not encounter any foreign objects during the translational movement, and the timing exceeds the translational movement time, the control mechanism stops detecting the infrared grating 206 signal, and the door assembly 2 begins to move downward. During the downward movement, if the force at any point on the pressure contact membrane 205 is greater than the preset pressure (0.02N in this embodiment), the pressure contact membrane 205 transmits the signal to the airport control mechanism in the UAV airport body 1. The control mechanism controls the door assembly 2 to stop operating. After the pressure is released, the control mechanism continues to control the door assembly 2 to close the door.

[0073] like Figure 10 As shown, when the UAV airport equipment is in its working environment, the external temperature sensor 207 detects the external temperature in real time, and the rain and snow sensor 102 detects the external weather conditions in real time, feeding back the detected information to the control mechanism in the UAV airport body 1 in real time. When the external temperature sensor 207 detects an external temperature below 0 degrees Celsius, and the rain and snow sensor 102 detects rain or snow, the control mechanism controls the heating wire pad 202 to heat the door shell 201 when both conditions occur simultaneously. After heating is turned on, when the external temperature is higher than a preset temperature (5 degrees Celsius in this embodiment) or when the rain and snow sensor 102 does not detect a rain or snow signal, the heating function is turned off after a preset heating time (30 minutes in this embodiment).

[0074] This embodiment provides a method for using a drone airport hatch, which solves the problems existing in the prior art where the hatch shell cannot be opened due to severe cold weather, and the safety issues of drone flight caused by foreign objects or drone deviation. It enhances the environmental adaptability and safety stability of the drone airport hatch.

[0075] While the specific embodiments of the present invention have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solutions of the present invention are still within the scope of protection of the present invention.

The driven arc-shaped guide rail module moves synchronously under the support of the supporting pulley module and the drive of the driven pulley module. The action of the second guide rail transmission module is consistent with that of the first guide rail transmission module. The first and second guide rail transmission modules drive the hatch assembly to move. The active pulley module drives the driven pulley module to enter the end of the arc-shaped track. The driven pulley module moves through the arc-shaped trajectory, thereby driving the driven arc-shaped guide rail module and the hatch assembly to move until the hatch shell presses against the sealing strip of the UAV airport body, completing the entire hatch closing action. When the hatch shell changes from closed to open, the main drive shaft assembly provides power. The active pulley module in the first guide rail transmission module moves translationally within the fixed arc-shaped guide rail module via a screw drive, driving the driven pulley module to move upward along the arc-shaped trajectory. This drives the driven arc-shaped guide rail module and the hatch assembly upward, causing the hatch assembly to detach from the sealing strip of the UAV airport body until the driven pulley module completely exits the end of the arc-shaped track. The second guide rail transmission module operates in the same way as the first guide rail transmission module. The first and second guide rail transmission modules drive the hatch assembly to move. The driven arc-shaped guide rail module moves under the support of the supporting pulley module and driven by the driven pulley module until the hatch shell is fully opened, completing the entire hatch opening action.
