Description

Technical Field

[0001] The present application relates to the technical field of unmanned aerial vehicles, and in particular to a blade folding mechanism and a parking device for unmanned aerial vehicles. Background Art

[0002] A drone airport is a special parking place for drones deployed in the wild or on the rooftops of urban buildings. Its advantage is to enhance the application and operation capabilities of drones and improve operation efficiency. When not working, the drones are on standby at the airport; when working, they can perform automatic flight operations. The main functions of a drone airport include parking drones, autonomous charging, autonomous inspection, precise landing, meteorological environment detection, real-time data transmission, route planning, etc.

[0003] The current drone airports are generally large, heavy, low in protection level, and difficult to transport, carry, and install. Therefore, when the drone is parked, its blades usually need to be folded to reduce the space occupied or reduce interference. In the related technology, there are drone airports that automatically fold the drone blades, but they often involve more parts, which increases the production cost. Summary of the invention

[0004] Based on this, it is necessary to provide a blade retracting mechanism that can reduce parts and reduce costs in order to solve the above technical problems.

[0005] A blade folding mechanism comprises a transmission assembly, a first folding assembly and a second folding assembly; the first folding assembly comprises a first matching structure and a first pushing structure, the first matching structure is connected between the first pushing structure and the transmission assembly, the first matching structure is configured to drive the first pushing structure to move in response to the movement of the transmission assembly, for folding blades protruding along a first direction; the second folding assembly is spaced apart from the first folding assembly, the second folding assembly comprises a second matching structure and a second pushing structure connected to the second matching structure, the second matching structure can cooperate with the transmission assembly to drive the second pushing structure to move, for folding blades protruding along a second direction; the first direction and the second direction are arranged at an angle.

[0006] It can be understood that, during the movement of the transmission component, the power can be transmitted to the first matching structure, and then the first matching structure transmits the power to the first pushing structure, so that the first pushing structure moves to retract the blades protruding along the first direction; the transmission component can also transmit power to the second matching structure, and the second matching structure can drive the second pushing structure to move, so that the second pushing structure retracts the blades protruding along the second direction. In other words, by respectively adapting a set of transmission components to the first retracting component and the second retracting component, the blades protruding along the first direction and the second direction can be retracted, achieving a dual purpose effect, without the need for additional transmission components, reducing the required parts and reducing production costs.

[0007] In some embodiments, the transmission assembly includes a first transmission member and a rotating arm connected to the first transmission member, the first transmission member can rotate around its own axis and is transmission-connected to the first matching structure, and the rotating arm is used to abut against the second matching structure.

[0008] It can be understood that the first transmission member can transmit power to the first matching structure, and the rotating arm can transmit power to the second matching structure, so as to realize the initial power transmission of the transmission component relative to the first folding component and the second folding component, which is beneficial for the two groups of folding components to operate independently and realize the folding of the blades in two different directions.

[0009] In some embodiments, the first mating structure includes a rotating part and a swing arm connected to the rotating part, and the rotating part can rotate around the axis of the rotating part under the action of the first transmission member. The swing arm is movably matched with the first pushing structure and is configured to drive the first pushing structure to reciprocate along the second direction in response to the rotation of the rotating part.

[0010] It can be understood that, through the transmission connection between the rotating part and the first transmission member, the swing arm is driven to rotate synchronously, and then the first pushing structure is driven to make a linear motion, pushing the protruding blades to rotate and achieve retraction; and, the swing arm increases the force arm, which can realize the driving of the first pushing structure under a smaller force, reducing the load on the first transmission member.

[0011] In some embodiments, one of the first pushing structure and the swing arm constructs a limit slot, and the other constructs a limit block, the length of the limit slot is set along the third direction, the limit block is inserted into the limit slot and can move in the limit slot; the first direction, the second direction and the third direction are set at angles to each other.

[0012] It can be understood that the rotation of the swing arm is converted into the movement of the first pushing structure through the cooperation between the limiting groove and the limiting block, and the structure is simple.

[0013] In some embodiments, the first folding assembly further includes a guide member, wherein the guide member is connected to the first pushing structure and is used to guide the first pushing structure to move along the second direction.

[0014] It can be understood that the provision of the guide member is conducive to guiding the first pushing structure to move along the second direction, thereby improving the stability of the movement of the first pushing structure.

[0015] In some embodiments, the second mating structure also includes a moving seat and an abutment arm, the moving seat is rotatably connected to the abutment arm, and is movably connected to the second pushing structure; the first transmission member can rotate around its own axis until the rotating arm abuts the abutment arm, the abutment arm is configured to push the moving seat to move in response to the abutment of the rotating arm, and the second pushing structure is configured to move in response to the movement of the moving seat.

[0016] It can be understood that the rotating arm can transmit power to the abutment arm, and the abutment arm transmits power to the moving seat, pushing the moving seat to move, converting the rotation into movement of the moving component, and then driving the movement of the pushing structure through the movement of the moving seat, thereby realizing the automatic retraction of the blades when closing the cabin.

[0017] In some embodiments, the movable seat is configured with an avoidance groove; the rotating arm can rotate in the opposite direction around the axis of the first transmission member to press the abutment arm to rotate relative to the movable seat into the avoidance groove.

[0018] It can be understood that when the rotating arm abuts the abutment arm, the force is transmitted to the abutment arm, and the abutment arm rotates relative to the moving seat. The avoidance groove of the moving seat forms an avoidance space for the rotation of the abutment arm, so that the abutment arm cannot continue to transmit the force to the moving seat, and then cannot push the moving seat, so that the pushing structure remains stationary, and the propeller blades have no action when the cabin door is open, and the propeller blades only have the function of automatically retracting when the cabin door is closed, thereby avoiding interference with the drone blades when the cabin door is open as much as possible.

[0019] In some embodiments, the second folding assembly also includes a second elastic member, and the movable seat is also configured with a receiving groove. The second elastic member is installed in the receiving groove and connected between the movable seat and the abutment arm. The abutment arm can rotate in the opposite direction relative to the movable seat under the action of the second elastic member.

[0020] It can be understood that the arrangement of the receiving groove is to facilitate the installation of the second elastic member, and the second elastic member is conducive to promoting the rotational reset of the abutting arm.

[0021] In some embodiments, the second pushing structure is rotatably connected to the door; the second folding assembly further includes a movable portion connected between the moving seat and the second pushing structure, and the moving seat drives the second pushing structure to swing relative to the door through the movable portion. In other words, the blades are folded by swinging the second pushing structure, and the operation is smoother.

[0022] In some embodiments, the second pushing structure includes a pushing portion and an extension arm, the pushing portion has a folding side and an assembly side arranged at intervals along the second direction, the assembly side is used to rotatably connect the cabin door, the extension arm is connected to the assembly side and protrudes along the first direction relative to the pushing portion, and the extension arm is movably connected to the moving seat; the moving seat can make a linear reciprocating motion along the second direction to drive the pushing portion to swing through the extension arm; the first direction and the second direction are set at an angle.

[0023] It can be understood that the extension arm is arranged to cooperate with the movable part to provide a force arm for the pushing part, which is conducive to converting the linear motion of the moving seat into the rotation of the pushing part.

[0024] In some embodiments, the movable part includes a movable groove and a limiting shaft, the limiting shaft is inserted in the movable groove and can move in the movable groove, one of the movable groove and the limiting shaft is arranged on the movable seat, and the other is arranged on the extension arm; the movable seat can drive the extension arm to drive the pushing part to swing through the abutment cooperation with the limiting shaft through the groove wall of the movable groove.

[0025] It can be understood that the cooperation between the limiting shaft and the movable groove facilitates the mobile seat to transmit power to the pushing structure, promotes the rotation of the pushing structure, and enables the pushing structure to push the blades by rotating to automatically retract the blades, which is flexible and simple.

[0026] In some embodiments, the second folding assembly further includes a first elastic member, the first elastic member being used to be connected between the movable seat and the cabin door, and the first elastic member being used to apply a force to the movable seat to move toward the abutment arm.

[0027] It can be understood that the first elastic member can provide an elastic force opposite to the moving direction of the moving seat, which is beneficial to promote the resetting of the moving seat.

[0028] In some embodiments, the second folding assembly further comprises a support base plate, the support base plate is slidably connected to the moving seat and rotatably connected to the second pushing structure, and the support base plate is used to connect the cabin door. It can be understood that the support base plate plays a role of stabilizing support for the movement of the moving seat and the swing of the second pushing structure.

[0029] The present application also provides a drone parking device, comprising the above-mentioned blade folding mechanism, a parking cabin and a door assembly; the parking cabin is constructed with a parking platform for parking the drone; the door assembly comprises a cabin door and a transmission arm, the transmission arm is connected between the cabin door and the parking platform, the cabin door can be movably connected to the parking platform through the transmission arm, the cabin door is equipped with the blade folding mechanism, and the transmission arm is connected to the transmission assembly in the blade folding mechanism; the cabin door has an open state and a closed state; in the closed state of the cabin door, the transmission assembly is configured to drive the blade folding mechanism to move in response to the movement of the transmission arm.

[0030] It is understandable that the parking platform provided on the parking cabin is conducive to providing stable support for the parking of the UAV, and the cabin door has the function of protecting and preventing dust from the UAV. The cabin door can be opened and closed by the movement of the transmission arm, and the operation is simple. At the same time, the transmission arm can also transmit power to the transmission assembly in the blade retracting mechanism, so that the first retracting assembly and the second retracting assembly can be moved respectively, thereby realizing the retraction of the blades protruding in the first direction and the second direction, realizing full power transmission, and no additional power is required, so that the weight and production cost of the UAV parking device are controlled.

The terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0049] The present application provides a blade folding mechanism for use at a drone parking airport. When the drone is parked at the airport, the blades of the drone can be pushed so that the blades of the drone are folded, thereby reducing the space occupied by the drone, which is beneficial to reducing the size of the drone parking airport and reducing the floor space occupied.

[0050] like Figure 1 and Figure 2As shown, illustratively, the blade folding mechanism 100 includes a transmission assembly 10, a first folding assembly 20 and a second folding assembly 30, and the first folding assembly 20 and the second folding assembly 30 are respectively connected to the transmission assembly 10. The transmission assembly 10 can transmit power to the first folding assembly 20 and the second folding assembly 30 respectively during the activity, so that the first folding assembly 20 and the second folding assembly 30 are both operated to achieve the folding of the blades in different directions. That is, the first folding assembly 20 and the second folding assembly 30 share a set of transmissions, and the first folding assembly 20 and the second folding assembly 30 do not need to be provided with separate transmission assemblies 10 one by one, which is conducive to reducing the number of parts used, thereby reducing costs and weight.

[0051] Please combine Figure 2 and Figure 3 Specifically, the first folding assembly 20 includes a first matching structure 21 and a first pushing structure 22. The first matching structure 21 is connected between the first pushing structure 22 and the transmission assembly 10. The first matching structure 21 is configured to drive the first pushing structure 22 to move in response to the movement of the transmission assembly 10, so as to fold the blades protruding along the first direction. In this way, the transmission assembly 10 can first transmit the power to the first matching structure 21, and then the first matching structure 21 will continue to transmit the power to the first pushing structure 22, completing the step-by-step transmission and conversion of the power, so that the first pushing structure 22 can push the blades protruding along the first direction to fold the blades.

[0052] Please combine Figure 2 , Figure 4 and Figure 5 Furthermore, the second folding assembly 30 is spaced apart from the first folding assembly 20; the second folding assembly 30 includes a second matching structure 31 and a second pushing structure 32 connected to the second matching structure 31; the second matching structure 31 can cooperate with the transmission assembly 10 to drive the second pushing structure 32 to move, and is used to fold the blades protruding along the second direction. In this way, the transmission assembly 10 can also transmit power to the second matching structure 31, and then the second matching structure 31 continues to transmit power to the second pushing structure 32, completing the step-by-step transmission and conversion of power, so that the second pushing structure 32 can push the blades protruding along the second direction to fold the blades.

[0053] In summary, when the transmission assembly 10 is in motion, it can transmit power to the first folding assembly 20 and the second folding assembly 30 respectively, and complete the step-by-step transmission and conversion of power inside the first folding assembly 20 and the second folding assembly 30, respectively, to achieve the purpose of folding the protruding blades along the first direction and the second direction. Such a setting not only improves the folding effect, but also simplifies the structure and realizes a lightweight design, without the need to add an additional transmission assembly 10, reduces the required parts, and reduces the production cost.

[0054] In the present application, the first direction, the second direction and the third direction are arranged at an angle in pairs. For the convenience of explanation, in the embodiments of the present application, the first direction is the y-axis, the second direction is the x-axis, and the third direction z is the axis.

[0055] like Figures 2 to 4 As shown, in an optional embodiment, the transmission assembly 10 includes a first transmission member 11, which can rotate around its own axis and is in transmission connection with the first matching structure 21. That is, the first transmission member 11 is rotated to achieve transmission connection with the first matching structure 21, and then the first pushing structure 22 is driven to move when the first matching structure 21 moves with it, so as to achieve the folding of the blades protruding along the first direction. For example, the first transmission member 11 and the first matching structure 21 can be gear-driven. Among them, the transmission connection between the first transmission member 11 and the first matching mechanism serves as the initial transmission of the movement in the first folding assembly 20. Further, the transmission assembly 10 also includes a rotating arm 12 connected to the first transmission member 11, and the rotating arm 12 is used to abut against the second matching structure 31. That is to say, when the first rotating member rotates until the rotating arm 12 can abut and cooperate with the second matching structure 31, the second matching structure 31 can be driven to actuate, and then the second pushing structure 32 is driven to achieve the folding of the blades protruding along the second direction. The blades are folded. The abutment between the rotating arm 12 and the second matching structure 31 serves as the initial transmission of the movement in the second folding assembly 30 .

[0056] like Figure 2 and Figure 3 As shown, in an optional embodiment, the first matching structure 21 includes a rotating part 211, and the rotating part 211 can rotate around the axis of the rotating part 211 under the action of the first transmission member 11. In this way, the power of the first transmission member 11 can be transmitted to the rotating part 211. Among them, the first transmission member 11 and the rotating part 211 can both adopt gears, and the two form a transmission connection by means of gear meshing. The gear meshing transmission method has high transmission efficiency and long service life. Alternatively, there can also be a belt drive between the first transmission member 11 and the rotating part 211, and the first transmission member 11 and the rotating part 211 can be connected to a pulley of the belt drive respectively. It only needs to satisfy the rotation of the first transmission member 11 to drive the rotating part 211 to rotate, and this is only used as an example.

[0057] like Figure 3As shown, further, the first matching structure 21 also includes a swing arm 212 connected to the rotating part 211, the swing arm 212 and the first pushing structure 22 can be movably matched, and is configured to drive the first pushing structure 22 to reciprocate along the second direction in response to the rotation of the rotating part 211. In other words, when the rotating part 211 rotates under the action of the first rotating member, it can drive the swing arm 212 to rotate synchronously, and then drive the first pushing structure 22 to do linear motion to meet the needs of the protruding blades in the first direction to be retracted. When the first pushing structure 22 moves along the second direction, it can push the protruding blades to rotate to adjust the angle and achieve retraction.

[0058] The swing arm 212 and the rotating part 211 can be integrally formed, in which case the swing arm 212 protrudes outwardly in the radial direction of the rotating part 211, and the remaining part of the rotating part 211 is provided with a plurality of teeth arranged at intervals around its own axis to mesh with the first rotating member for transmission. Of course, the swing arm 212 and the rotating part 211 can also be separately formed, in which case the rotating part 211 can be a separate gear structure, and the swing arm 212 can be eccentrically arranged relative to the rotating part 211, so that part of the swing arm 212 protrudes in the radial direction of the rotating part 211. For example, the swing arm 212 can directly adopt a cam.

[0059] It can be understood that the setting of the swing arm 212 plays the role of extending the lever arm, so that the swing arm 212 has sufficient space for movement when cooperating with the first pushing structure 22, and ensures that the swing arm 212 can drive the first pushing structure 22 to move a sufficient distance to push the blades to be fully retracted. In addition, the setting of the swing arm 212 can satisfy the driving of the first pushing structure 22 with a smaller action, reducing the load on the first transmission member 11.

[0060] like Figure 3 As shown, in some embodiments, one of the first pushing structure 22 and the swing arm 212 is configured with a limiting groove 221, and the other is configured with a limiting block 2121. The length of the limiting groove 221 is set along the third direction, and the limiting block 2121 is inserted into the limiting groove 221 and can move in the limiting groove 221. In other words, when the swing arm 212 swings with the rotating part 211, the first pushing structure 22 can be driven to move linearly by the contact between the groove wall of the limiting groove 221 and the limiting block 2121. Such a setting forms a three-link mechanism with a simple structure and higher stability.

[0061] In some specific embodiments, the limiting groove 221 is provided in the first pushing structure 22, and may or may not penetrate along the thickness direction of the first pushing structure 22; and the limiting block 2121 is convexly provided on the swing arm 212, so as to be inserted into the limiting groove 221. Of course, it is also possible that the first pushing structure 22 is configured with the limiting block 2121, and the swing arm 212 is configured with the limiting groove 221.

[0062] like Figure 3 As shown, in a further embodiment, the first folding assembly 20 further includes a guide member 23, which is connected to the first pushing structure 22 and is used to guide the first pushing structure 22 to move along the second direction. In other words, the guide member 23 has a guiding and limiting function on the first pushing structure 22, thereby improving the stability of the movement of the first pushing structure 22, reducing the deflection vibration of the first pushing structure 22, and thus improving the safety of the blades during the folding process.

[0063] In a specific embodiment, one side of the first pushing structure 22 along the third direction is connected to a guide member 23. Alternatively, both sides of the first pushing structure 22 along the third direction are correspondingly connected to guide members 23, which further improves the guiding effect and promotes stable movement.

[0064] like Figure 3 As shown, in some specific embodiments, the guide member 23 includes a guide rod 231, and a guide block 233 with a sliding hole can be convexly provided on the side of the first pushing structure 22 away from the blade, and the guide rod 231 is inserted into the sliding hole to be slidably connected with the guide block 233 to achieve the movement guidance of the first pushing structure 22. Of course, a slider can be convexly provided on the side of the first pushing structure 22 away from the blade, and the slider is concavely provided with an arc groove to cooperate with the guide rod 231 through the arc groove. Alternatively, the guide member 23 can also be a block structure, in which case a slide groove can be concavely provided on the side of the first pushing structure 22 away from the blade, and a portion of the guide member 23 extends into the slide groove for sliding connection. This is only an example.

[0065] like Figure 3 As shown, more specifically, guide bases 232 are provided at both ends of the guide rod 231 along its own axial direction, so as to fix the guide rod 231 at a target position, for example, at a side of the door 301 facing the blade.

[0066] The first pushing structure 22 may be a plate-shaped structure or a rod-shaped structure.

[0067] See also Figure 2 , Figure 4 and Figure 5In an optional embodiment, the second matching structure 31 further includes a moving seat 311 and an abutting arm 312, the moving seat 311 is rotatably connected to the abutting arm 312, and is movably connected to the second pushing structure 32; the first transmission member 11 can rotate around its own axis until the rotating arm 12 abuts against the abutting arm 312, the abutting arm 312 is configured to push the moving seat 311 to move in response to the abutment of the rotating arm 12, and the second pushing structure 32 is configured to move in response to the movement of the moving seat 311. In this way, the rotating arm 12 can transmit power to the abutting arm 312, and the abutting arm 312 continues to transmit power to the moving seat 311, promoting the movement of the moving seat 311, and the moving seat 311 moves to continue to transmit power to the second pushing structure 32.

[0068] like Figures 4 to 7 As shown, in a further embodiment, the moving seat 311 is configured with an avoidance groove 3111; the rotating arm 12 can rotate in the opposite direction around the axis of the first transmission member 11 to press the abutting arm 312 to rotate relative to the moving seat 311 into the avoidance groove 3111. In other words, the setting of the avoidance groove 3111 provides an avoidance space for the rotation of the abutting arm 312, so that the abutting arm 312 can be accommodated in the avoidance groove 3111 under the action of the rotating arm 12 during the process that the rotating arm 12 can rotate in the opposite direction around the axis of the first transmission member 11, and no thrust toward the moving seat 311 is generated. Therefore, the moving seat 311 remains stationary, thereby prompting the second pushing structure 32 to remain stationary as well, and no action is taken on the blades. This is applicable to the opening process of the drone parking airport. At this time, there is no need to retract the drone blades. The drone is about to rise from the drone parking airport, and the drone blades are unfolded accordingly, which can avoid interference with the unfolding of the blades.

[0069] In actual use, the movable seat 311 is provided with a limit baffle for limiting the rotation of the abutment arm 312, so as to limit the clockwise rotation of the abutment arm 312. The abutment arm 312 has a first position and a second position relative to the movable seat 311. In the first position, the abutment arm 312 is limited by the action of the limit baffle and cannot rotate upward, so the abutment arm 312 can withstand the abutment force of the rotating arm 12 and transmit it to the movable seat 311, which is conducive to the folding of the blades. In the second position, the abutment arm 312 is accommodated in the avoidance groove 3111.

[0070] When the drone parking airport is closed, the abutment arm 312 is in the first position, and the rotating arm 12 can abut against the abutment arm 312 after rotating forward around the axis of the first transmission member 11. At this time, the abutment arm 312 will exert a force on the moving seat 311 to move away from the abutment arm 312 under the pressure of the rotating arm 12, and then use the moving seat 311 to drive the second pushing structure 32 to move, so as to achieve the folding of the blades. When the drone parking airport is opened, the rotating arm 12 rotates in the opposite direction around the first rotating shaft 3021 until it contacts the abutment arm 312, so as to press the abutment arm 312 to rotate in the opposite direction relative to the moving seat 311 so as to be accommodated in the avoidance groove 3111, and the force cannot be further transmitted, so as to achieve the second pushing structure 32 to act when the drone parking airport is closed, and not to act when the drone parking airport is opened.

[0071] like Figure 6 As shown, in a specific embodiment, the rotation angle α of the abutment arm 312 ranges from 0°≤α≤90°. When the rotating arm 12 rotates to abut against the abutment arm 312, at this time, the angle α of the abutment arm 312 maintains α=0°, and the abutment arm 312 can push the moving seat 311 to move, and the abutment arm 312 moves with the moving seat 311 until the abutment arm 312 is separated from the rotating arm 12. When the rotating arm 12 rotates in the opposite direction to abut against the abutment arm 312, at this time, the abutment arm 312 can rotate downward because there is no limiting effect at the bottom, that is, the rotation angle of the abutment arm 312 rotates from 0 to 90 degrees. When the abutment arm 312 rotates to 90 degrees, the rotating arm 12 is separated from the abutment arm 312. This is only an example, and it can also be separated from the rotating arm 12 when the abutment arm 312 rotates to 80 degrees.

[0072] like Figures 5 to 7 As shown, in a specific embodiment, the abutment arm 312 includes an abutment seat body 3121 and a roller 3122, the roller 3122 is rotatably connected to the abutment seat body 3121, and the abutment seat body 3121 is rotatably connected to the movable seat 311. The arrangement of the roller 3122 can reduce the friction between the rotating arm 12. Of course, the roller 3122 can also use a bearing, as long as it can reduce the friction. Among them, the movable seat 311 is provided with a receiving groove 3112, and a portion of the abutment seat body 3121 extends into the receiving groove 3112 and is rotatably connected through a rotating shaft. The abutment seat body 3121 is provided with an assembly groove, and a portion of the roller 3122 extends into the assembly groove and is rotatably connected through a rotating shaft.

[0073] In a specific embodiment, the rotating arm 12 is provided with an abutting inclined surface at the protruding portion, and the abutting inclined surface is used to abut against the abutting arm 312. Such a setting, on the one hand, can increase the abutting area and prolong the contact time with the abutting arm 312. During the closing process of the drone parking airport, it can ensure that the power is fully transmitted to the moving seat 311 through the abutting arm 312, that is, the moving seat 311 moves a sufficient distance to drive the second pushing structure 32 to fully move and ensure that the blades are fully retracted; on the other hand, the inclined surface is conducive to the separation of the rotating arm 12 relative to the abutting arm 312.

[0074] like Figures 5 to 7 As shown, in a further embodiment, the second folding assembly 30 further includes a second elastic member 33, and the movable seat 311 is further configured with a receiving groove 3112. The second elastic member 33 is installed in the receiving groove 3112 and connected between the movable seat 311 and the abutting arm 312. The abutting arm 312 can rotate in the opposite direction relative to the movable seat 311 under the action of the second elastic member 33. The second elastic member 33 can be a tension spring; or the second elastic member 33 can be a torsion spring, which is sleeved on the rotating shaft corresponding to the abutting seat body 3121. In this way, when the abutting arm 312 rotates, the second elastic member 33 will be elastically deformed, and the second elastic member 33 has a force on the abutting arm 312 in the opposite direction of the rotation direction of the abutting arm 312, which is conducive to the reset of the abutting arm 312.

[0075] like Figure 4 and Figure 5 As shown, in a further embodiment, the second folding assembly 30 further includes a support base plate 34, which is slidably connected to the moving seat 311 and rotatably connected to the second pushing structure 32. In this way, the support base plate 34 can provide stable support for the sliding of the moving seat 311 and the rotation of the second pushing structure 32; and, by using the setting of the support base plate 34, it is convenient to disassemble and assemble the second folding assembly 30 as a whole relative to the door 301 of the drone parking airport. The support base plate 34 can directly cooperate with the moving seat 311 and the second pushing structure 32, without making too many structural improvements to the door 301 of the drone parking airport, and the manufacturing is more convenient. Among them, the support base plate 34 can be connected to the door 301 by screws, and a plurality of screws are provided and arranged at intervals to improve the connection reliability.

[0076] Among them, the upper and lower parts of the support base plate 34 along the vertical direction are extended with assembly bosses 342, which are rotatably connected with the pushing part 321 through the rotating shaft. The aforementioned extension part is arranged in the middle of the two assembly bosses 342 to ensure that the force arms toward the two assembly bosses 342 are basically the same, thereby improving the assembly stability.

[0077] like Figure 5As shown, in an optional embodiment, the second folding assembly 30 further includes a first elastic member 35, the first elastic member 35 is connected between the supporting base plate 34 and the moving seat 311, and the first elastic member 35 is used to apply a force to the moving seat 311 to move toward the abutment arm 312. When the moving seat 311 moves, the first elastic member 35 is elastically deformed, so that the first elastic member 35 exerts an elastic force on the moving seat 311 in the opposite direction of the moving direction of the moving seat 311, which is conducive to the resetting of the moving seat 311.

[0078] Further, the supporting base plate 34 is provided with an assembly hole 341, and the movable seat 311 is slidably inserted in the assembly hole 341 and can slide in the assembly hole 341. Such a setting not only enables the linear motion of the movable seat 311, but also guides the movement of the movable seat 311. When a first elastic member 35 is provided, the first elastic member 35 is accommodated in the assembly hole 341 and abuts between the hole wall of the assembly hole 341 and the movable seat 311. In order to improve the compactness of the structure, a mounting hole can be provided at one end of the movable seat 311 away from the abutting arm 312, and part of the first elastic member 35 is accommodated in the mounting hole and abuts between the hole wall of the mounting hole and the hole wall of the assembly hole 341. The mounting hole is not connected to the aforementioned accommodating groove 3112 to maintain the independent assembly of the first elastic member 35 and the second elastic member 33 and reduce the interference effect.

[0079] like Figure 4 and Figure 5 As shown, in a further embodiment, the second pushing structure 32 includes a pushing portion 321 and an extension arm 322, the pushing portion 321 has a folding side 3211 and an assembly side 3212 arranged at intervals along the second direction, the assembly side 3212 is rotatably connected to the support base plate 34, the extension arm 322 is connected to the assembly side 3212 and protrudes relative to the pushing portion 321 along the first direction, and the extension arm 322 is movably connected to the moving seat 311; the moving seat 311 can make a linear reciprocating motion along the second direction to drive the pushing portion 321 to swing through the extension arm 322. Further, the second folding assembly 30 also includes a movable portion 36 connected between the moving seat 311 and the extension arm 322. That is, the setting of the extension arm 322 to cooperate with the movable portion 36 is conducive to converting the linear motion of the moving seat 311 into the rotation of the pushing portion 321. Therefore, the extension arm 322 is used to provide a force arm for the pushing portion 321, which is conducive to motion transmission. The extension arm 322 is provided with a groove, which is adapted to the edge of the assembly side 3212 of the pushing portion 321 , and a portion of the assembly side 3212 is embedded in the groove. The movable portion 36 is connected between the moving seat 311 and the extension arm 322 .

[0080] Among them, the pushing part 321 is provided with a warping part on the folding side 3211, which is obliquely extended toward the side away from the cabin door 301. In other words, the warping part is obliquely extended toward one side of the blade. When the pushing part 321 is installed on the cabin door 301, the cabin door 301 is correspondingly surrounded by a parking space for storing the drone, and the warping part is obliquely extended toward the parking space. The setting of the warping part is equivalent to reducing the distance between the pushing part 321 and the blade, which is more conducive to pushing the blade to fold. Among them, the warping part can be curved in an arc shape to adapt to the edge of the blade and reduce wear.

[0081] like Figure 5 As shown, in a specific embodiment, the movable portion 36 includes a movable groove 361 and a limiting shaft 362, the limiting shaft 362 is inserted into the movable groove 361 and can move in the movable groove 361, one of the movable groove 361 and the limiting shaft 362 is arranged on the movable seat 311, and the other is arranged on the extension arm 322; the movable seat 311 can drive the extension arm 322 to drive the push portion 321 to swing through the abutment and cooperation between the groove wall of the movable groove 361 and the limiting shaft 362. In this way, when the movable seat 311 moves, the movable groove 361 is driven to move synchronously, and the groove wall of the movable groove 361 abuts against the limiting shaft 362 to drive the extension arm 322 to swing, thereby driving the push portion 321 to swing synchronously, so as to achieve folding and resetting. Among them, the movable groove 361 is recessed at the lower position of the movable seat 311, and the limiting shaft 362 is convexly arranged at the extension end of the extension arm 322. In other embodiments, the movable groove 361 may be disposed on the extension portion, and the limiting shaft 362 may be disposed on the movable seat 311 .

[0082] In a specific embodiment, the pushing portion 321 may be a plate-shaped structure or a columnar structure. When the pushing portion 321 is a plate-shaped structure, the contact area with the blade can be ensured, and the second matching structure 31 can be shielded, making it more aesthetically pleasing.

[0083] See also Figures 8 to 11 The present application also provides a drone parking device 1000, comprising the above-mentioned blade folding mechanism 100, a parking cabin 200 and a door assembly 300; the parking cabin 200 is constructed with a parking platform 201 for parking the drone; the door assembly 300 includes a cabin door 301 and a transmission arm 302, the transmission arm 302 is connected between the cabin door 301 and the parking platform 201, the cabin door 301 can be movably connected to the parking platform 201 through the transmission arm 302, the cabin door 301 is installed with a blade folding mechanism 100, and the transmission arm 302 is connected to the transmission assembly 10 in the blade folding mechanism.

[0084] The hatch 301 has an open state and a closed state; in the closed state, the hatch 301 and the parking platform 201 cooperate to enclose a parking space, the parking platform 201 provides a support site for the parking of the drone, and the hatch 301 can provide dustproof and protection for the parking of the drone. The blade retracting mechanism 100 is installed on the inner wall of the hatch 301, without occupying the space outside the parking space.

[0085] When the hatch 301 is closed, the transmission assembly 10 is configured to drive the blade retracting mechanism 100 to move in response to the movement of the transmission arm 302. That is, when the hatch 301 is closed, the transmission arm 302 drives the hatch 301 to close while transmitting power to the transmission assembly 10 in the blade retracting mechanism 100, and the transmission assembly 10 transmits the power to the first retracting assembly 20 and the second retracting assembly 30 respectively, so as to achieve the retracting of the blades protruding in the first direction and the second direction.

[0086] That is to say, the transmission arm 302 can synchronously transmit power to the cabin door 301 and the blade retraction mechanism 100, so as to realize automatic retraction of the UAV blades while closing the cabin door 301. There is no need to set up an additional power source 400 for the blade retraction mechanism 100, and no additional installation space will be occupied, which is beneficial to controlling the weight of the UAV parking device, saving costs, and promoting large-scale production.

[0087] like Figure 8 and Fig. 9 As shown, in some embodiments, there are at least two doors 301, each door 301 is provided with a corresponding transmission arm 302, each door 301 is movably connected to the parking platform 201 through its corresponding transmission arm 302, and each door 301 is spliced ​​and matched to form a parking space for storing drones together with the parking platform 201. The provision of multiple doors 301 is more conducive to the individual drive of each door 301; and multiple doors 301 also means the provision of multiple transmission arms 302, each transmission arm 302 can correspondingly drive a retracting structure to improve the efficiency of retracting the blades.

[0088] For example, when there are two doors 301, each door 301 is in an inverted L-shape, and each door 301 is connected to a transmission arm 302 on both sides along the Y-axis direction to improve the connection reliability and activity stability of the door 301 relative to the parking platform 201. Therefore, a blade retracting mechanism 100 can be connected to each transmission arm 302 to retract multiple blades of the drone.

[0089] Please combine Figure 1 , Figure 2 , Figure 8 and Fig. 9In an optional embodiment, the transmission arm 302 includes a first rotating shaft 3021, a second rotating shaft 3022, and a transmission unit 3023 connected between the first rotating shaft 3021 and the second rotating shaft 3022. The first rotating shaft 3021 is connected to the first transmission member 11 in the transmission assembly 10 to drive the first transmission member 11 to rotate. The second rotating shaft 3022 is rotatably connected to the parking platform 201. Among them, the second rotating shaft 3022 can also be connected to the power source 400, and the power source 400 drives the second rotating shaft 3022 to rotate, so as to transmit power to the first rotating shaft 3021 through the transmission unit 3023, and then drive the first transmission member 11 to move through the first rotating shaft 3021. Of course, it can also be that one end of the first rotating shaft 3021 is connected to the power source 400, and the other end is connected to the first transmission member 11, and the second rotating shaft 3022 is rotatably connected to the parking platform 201. It can be used as long as it can realize the opening and closing (i.e. opening and closing) of the cabin door 301, which is only used as an example here. When the power source 400 is connected to the second rotating shaft 3022 , it is disposed on the parking platform 201 ; when the power source 400 is connected to the first rotating shaft 3021 , it is disposed on the cabin door 301 .

[0090] The transmission unit 3023 may be a belt drive, a chain drive, or a gear drive. The power source 400 may be a motor drive to achieve automatic opening and closing of the hatch 301; of course, the power source 400 may also be a hand wheel to facilitate manual operation. The hand wheel may be detachably connected to the second rotating shaft 3022.

[0091] In some specific embodiments, taking chain transmission as an example, the transmission unit 3023 includes a driving wheel, a driven wheel and a transmission chain, the driven wheel is installed on the first rotating shaft 3021, the driving wheel is installed on the second rotating shaft 3022, and the transmission chain is tensioned between the driving wheel and the driven wheel; and the second rotating shaft 3022 is connected to the power source 400. In this way, the power source 400 first transmits power to the driving wheel on the second rotating shaft 3022, and then the transmission chain transmits power to the driven wheel, so that the driven wheel rotates with the first rotating shaft 3021, thereby realizing power transmission. Chain transmission has no elastic sliding and slipping phenomenon, the average transmission ratio is accurate, the operation is reliable, and the efficiency is high; and the chain transmission has a large transmission power, a strong overload capacity, and a small transmission size under the same working condition, which can be integrated in a smaller space to improve the compactness of the structure. In addition, the tensioning force required for the chain transmission is small, the pressure acting on the shaft is small, and it can work in harsh environments such as high temperature, humidity, dust, and pollution.

[0092] In actual use, the transmission arm 302 further includes a shell 3024, and the shell 3024 is provided with an assembly cavity for installing the aforementioned transmission unit 3023 and other structures, which plays a role of protection and aesthetics.

[0093] like Figures 2 to 5 , Fig.10 and Fig.11 As shown, it can be seen from the above that when the hatch 301 is closed, the transmission arm 302 drives the first transmission member 11 to rotate, and the first transmission member 11 is meshed with the rotating part 211 to drive the rotating part 211 to rotate, and the rotating part 211 drives the swing arm 212 to rotate, so as to use the limit block 2121 to abut against the groove wall of the limit groove 221, drive the first pushing structure 22 to make a linear motion along the second direction, and then push the blade protruding along the first direction to rotate, so as to achieve folding. At the same time, the rotation of the first transmission member 11 will drive the rotating arm 12 to rotate synchronously, so as to abut against the front end of the abutting arm 312 at the position corresponding to the abutting arm 312. At this time, as the rotating arm 12 continues to move, it will exert an action along the X-axis direction on the abutting arm 312, and then push the moving seat 311 to move rightward along the X-axis through the abutting arm 312. The movable seat 311 pulls the extension arm 322 through the abutment cooperation between the groove wall of the movable groove 361 and the limiting shaft 362, and then drives the pushing part 321 to swing toward the side close to the blade through the extension arm 322 (such as Fig.11 The paddle blades protruding in the second direction are pushed to rotate to achieve folding.

[0094] In this process, due to the setting of the upper limit groove 221 of the first pushing structure 22, the moving range of the limit block 2121 can be limited, thereby limiting the moving range of the first pushing structure 22; and, due to the meshing transmission of the first transmission member 11 and the rotating part 211, the swing arm 212 is prompted to swing around the axis of the rotating part 211, which is conducive to the reset of the first pushing structure 22. At the same time, due to the setting of the abutting inclined surface on the rotating arm 12, as the rotating arm 12 continues to rotate, it can pass over the abutting arm 312. At this time, the abutting arm 312 loses the abutting force of the rotating arm 12. Under the action of the first elastic member 35, the moving seat 311 and the abutting arm 312 are both moved closer to the rotating arm 12 along the X-axis to reset; and, during the reset process, the moving seat 311 uses the cooperation of the movable groove 361 and the limit shaft 362 to pull the extension arm 322, so that the pushing part 321 rotates counterclockwise to reset.

[0095] During the opening process of the hatch 301, the rotating part 211 and the first transmission member 11 are always meshed and transmitted, and the first pushing structure 22 still performs linear motion. Since the blades protruding along the first direction have been retracted by the first pushing structure 22 during closing, the linear motion of the first pushing structure 22 will not interfere with the blades. At the same time, the rotating arm 12 rotates with the rotating part 211, so that when it abuts against the abutting arm 312, the abutting arm 312 rotates downward with the rotation of the rotating arm 12 to be accommodated in the avoidance groove 3111, until the rotating arm 12 passes over the abutting arm 312, and the abutting arm 312 is reset under the action of the second elastic member 33.

[0096] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0097] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
