Patent Description:
After unmanned aerial vehicles land, the states of rotor blades are different. If the blades are randomly placed, because the area occupied by the blades is larger than the area occupied by the unmanned aerial vehicles themselves, a large amount of space is occupied when the blades are stored. As shown in <FIG>, in the related art, the blades are folded by means of manual blade poking, and manual blade poking is not conducive to the automatic use of unmanned aerial vehicles. <CIT> discloses an unmanned aerial vehicle ground station.

The object of the present invention is to provide an unmanned aerial vehicle parking device that can automatically collapse the blades of an unmanned aerial vehicle while facilitating the subsequent take-off of an unmanned aerial vehicle.

In order to achieve the above object, the invention adopts the technical solutions below:

The parking platform is used to carry an unmanned aerial vehicle; a blocking assembly includes a driving rod and a stop bar, wherein the stop bar is connected to the driving rod, and the driving rod is configured to move between a first position and a second position; when the driving rod moves from the first position to the second position, the driving rod drives the stop bar to rotate so that the stop bar lies flat relative to the parking platform, and the stop bar may not block a blade of the unmanned aerial vehicle from rotating; when the driving rod moves from the second position to the first position, the stop bar rotates relative to the driving rod and abuts against the parking platform so that the stop bar erects relative to the parking platform, and the stop bar may block the rotation of the blade of the unmanned aerial vehicle.

In some alternative embodiments, the blocking assembly comprises a movable rod respectively connected to the driving rod and the stop bar;
wherein the driving rod is configured to move between the second position and a third position, and the stop bars are all placed flat relative to the parking platform; when the driving rod moves from the second position to the third position, the driving rod drives the movable rod to rotate around an axis perpendicular to the parking platform, and a projection of the stop bar on the parking platform completely overlaps with the parking platform; when the driving rod moves from the third position to the second position, the movable rod rotates relative to the driving rod and abuts against the driving rod in a plane perpendicular to the parking platform, and the projection of the stop bar on the parking platform partially overlaps with the parking platform.

In some alternative embodiments, the blocking assembly further comprises a stop block fixed to the parking platform, the stop block having a first surface provided adjacent to the parking platform and a second surface provided opposite the parking platform, the first surface being provided with a first blocking portion, and the second surface being provided with a second blocking portion;.

In some alternative embodiments, the end portion of the first blocking portion toward one end of the stop bar is rounded off.

In some alternative embodiments, the unmanned aerial vehicle parking device further comprises a first re-centering assembly and a second re-centering assembly, wherein the first re-centering assembly and the second re-centering assembly are both fixed to the parking platform, and the first re-centering assembly and the second re-centering assembly are together configured to push the unmanned aerial vehicle from a parking position to a re-centering position;

In some alternative embodiments, at least one of the first driving mechanism and the second driving mechanism is a lead screw driving mechanism.

In some alternative embodiments, the unmanned aerial vehicle parking device comprises a control board, and the control board is electrically connected to the first driving mechanism and the second driving mechanism respectively, so that while the first driving mechanism drives the first movable seat to move, the second driving mechanism drives the second movable seat to move.

In some alternative embodiments, the unmanned aerial vehicle parking device comprises a charging interface, the charging interface being fixed to the first movable seat, the charging interface being electrically connected to the control board, and the charging interface being configured to connect to a power source of the unmanned aerial vehicle.

In some alternative embodiments, the charging interface is a pogo pin.

Advantageous effects of embodiments of the present invention are as follows: in an embodiment of the present invention, when the driving rod in the blocking assembly drives to the first position, the stop bar is converted from the flat-lying state to the erecting state so that it can block the rotation of the blade of the unmanned aerial vehicle, so as to play the role of collapsing the blades of the unmanned aerial vehicle. When the driving rod in the blocking assembly drives to the second position, the stop bar is converted from the erecting state to the flat-lying state, and the stop bar no longer blocks the rotation of the blade of the unmanned aerial vehicle, so as to ensure the normal take-off of the unmanned aerial vehicle. In addition, compared to other unmanned aerial vehicle parking devices, the embodiment of the present invention requires fewer structures to achieve the collapsing of the blades of an unmanned aerial vehicle, and the structure of the unmanned aerial vehicle parking device is more compact, facilitating the miniaturization of the unmanned aerial vehicle parking device.

In order to illustrate specific embodiments of the present invention or the technical solutions in the prior art more clearly, the following will briefly introduce the drawings that need to be used in the description of the specific embodiments or the prior art. Throughout the drawings, like elements or portions are generally identified by like reference numerals. In the drawings, elements or portions may not necessarily be drawn to the actual scale.

The technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments. The description of at least one exemplary embodiment below is actually only illustrative and does not serve as any limitation on the present disclosure, and the application or use thereof.

Techniques, methods, and equipment known to those of ordinary skill in the relevant art may not be discussed in detail.

In the description of the present disclosure, it should be noted that the orientation or positional relationships indicated by directional words such as "front, back, up, down, left, right", "transverse, vertical, perpendicular, horizontal", and "top and bottom" are usually based on the orientation or positional relationships shown in the accompanying drawings, only for the convenience of describing the present disclosure and simplifying the description. In the absence of contrary descriptions, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the scope of protection of the present disclosure; the directional terms "inside and outside" refer to the inside and outside of the contour relative to each component itself.

In describing the present disclosure, it should be noted that the use of the terms "first", "second", and the like to define components and parts is merely to facilitate the distinction of the corresponding components and parts, and such terms are not intended to have a special meaning unless otherwise indicated, and thus should not be construed as limiting the scope of the present invention.

Referring to examples shown in <FIG>, <FIG> is a schematic structural diagram of an unmanned aerial vehicle parking device <NUM> provided by an embodiment of the present disclosure, <FIG> is an explosive view of the structure of the unmanned aerial vehicle parking device <NUM> shown in <FIG>, and <FIG> is a schematic structural diagram of the unmanned aerial vehicle parking device <NUM> shown in <FIG> from another angle. The unmanned aerial vehicle parking device <NUM> comprises a parking platform, a first re-centering assembly, a second re-centering assembly, a blocking assembly, and a control board. The parking platform is not only a bearing structure of the unmanned aerial vehicle, but also a mounting support structure for each component mentioned above. The first re-centering assembly and the second re-centering assembly are both mounted to the parking platform and are both electrically connected to the control board. The first re-centering assembly and the second re-centering assembly are used together to move the unmanned aerial vehicle from the parking position to the re-centering position. The first re-centering assembly may be connected to the blocking assembly. When the unmanned aerial vehicle moves from the parking position to the re-centering position, the blocking assembly can block the rotation of the blade of the unmanned aerial vehicle. Under the drive of the first re-centering assembly, the blade is driven to rotate relative to the motor of the unmanned aerial vehicle, so that the blade collapses into an area enclosed by the fuselage of the unmanned aerial vehicle and two adjacent motors. When the first re-centering assembly is reset, the blocking assembly can no longer block the blade rotation of the unmanned aerial vehicle under the drive of the first re-centering assembly, so as to ensure the normal take-off of the unmanned aerial vehicle.

In order to be able to clearly describe each orientation in the following, each direction is defined by means of the coordinate system in <FIG>. The coordinate axis X represents the first direction, which is the direction of the relative arrangement of the two first elongated holes 11a of the parking platform and which is also the direction in which the two first movable seats <NUM> of the first re-centering assembly approach or move away from each other; the coordinate axis Y represents the second direction, which is the relative arrangement direction of the two second elongated holes 11b of the parking platform, and is also the direction in which the two second movable seats <NUM> of the second re-centering assembly approach or move away from each other; the coordinate axis Z represents the third direction, which is perpendicular to the first direction and the second direction, in other words, perpendicular to the plane where the parking plate <NUM> of the parking platform is located.

Based on the above orientation definition, the detailed structure of the parking platform, the blocking assembly, and the re-centering assembly will be described next in detail with reference to the illustrations in the drawings. The terms used below, such as "up", "down", "top", "bottom", etc., to indicate orientation or positional relationships, are all relative to the third direction Z. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

With regard to the above-mentioned parking platform, the parking platform comprises a parking plate <NUM> and a main body of the parking platform. The main body of the parking platform is provided with a cavity and an opening communicating the cavity with the outside. The cavity is configured to accommodate the first re-centering assembly and the second re-centering assembly. The parking plate <NUM> is mounted at the opening and closes the opening; the parking plate <NUM> is configured to bear the unmanned aerial vehicle. The parking plate <NUM> is provided with the first elongated hole 11a and the second elongated hole 11b. The first elongated hole 11a is configured to cooperate with the first re-centering assembly, so as to guide the first re-centering assembly. The second elongated hole 11b is configured to cooperate with the second re-centering assembly to guide the second re-centering assembly. Specifically, the number of the first elongated holes 11a and the second elongated holes 11b is respectively two. In the first direction X, two first elongated holes 11a are arranged at intervals in the parking plate <NUM>. In the second direction Y, two second elongated holes 11b are arranged at intervals in the parking plate <NUM>. In the third direction Z, the two first elongated holes 11a are symmetrically arranged with the line segment formed by connecting the two second elongated holes 11b as the axis of symmetry.

For the first re-centering assembly described above, referring to the example shown in <FIG> in conjunction with <FIG>, the first re-centering assembly includes a first driving mechanism <NUM> and a first movable seat <NUM>. The first driving mechanism <NUM> is fixed in the cavity of the main body of the parking platform, and the first driving mechanism <NUM> is electrically connected to the control board. The first movable seat <NUM> is embedded in the first elongated hole 11a and is movably connected to the first driving mechanism <NUM>, and the first movable seat <NUM> is used to be connected to the blocking assembly, thereby driving the blocking assembly to move relative to the parking plate <NUM>. Specifically, the first driving mechanism <NUM> includes a first driving motor <NUM>, a first driving wheel <NUM>, a first driven wheel <NUM>, a first timing belt <NUM>, and a first lead screw <NUM>. The first driving motor <NUM> and the first lead screw <NUM> are both fixed to the main body of the parking platform, and the first lead screw <NUM> can rotate about its own axis. The first driving wheel <NUM> is fixed to a rotating shaft of the first driving motor <NUM>, the first driven wheel <NUM> is fixed to one end of the first lead screw <NUM>, and the first timing belt <NUM> is sleeved between the first driving wheel <NUM> and the first driven wheel <NUM>. The first lead screw <NUM> is provided with an external thread, the first movable seat <NUM> is provided with an internal thread adapted to the external thread, and the first movable seat <NUM> is threadedly connected to the first lead screw <NUM> such that in the first direction X, the first driving mechanism <NUM> is configured to drive the first movable seat <NUM> to move relative to the parking plate <NUM>. Illustratively, the number of the first movable seat <NUM> is two, and one first movable seat <NUM> is embedded in the first elongated hole 11a. The internal threads of the two first movable seats <NUM> are oppositely rotated. When the first driving motor <NUM> drives the first movable seat <NUM> to move, the two first movable seats <NUM> are close to each other or far away from each other due to the opposite thread rotating directions. In this way, the unmanned aerial vehicle can be parked on the parking plate <NUM> while two opposite sides of the unmanned aerial vehicle are acted on, in order to align the unmanned aerial vehicle's posture on the two opposite sides in the first direction X. In addition, since the two first movable seats <NUM> share one driving mechanism, not only the manufacturing cost of the unmanned aerial vehicle parking device <NUM> can be saved, but also the space occupied by the first re-centering assembly can be saved, which is beneficial to the miniaturization of the unmanned aerial vehicle parking device <NUM>. It could be understood that the two first movable seats <NUM> may also be driven towards or away from each other by separate driving mechanisms, and the manner in which the first driving mechanism drives the first movable seat <NUM> is not particularly limited by the present disclosure. For example, the first driving mechanism may employ a motor gear rack structure or like structures capable of linear motion.

With respect to the second re-centering assembly described above, and with continuing reference to the example shown in <FIG> in conjunction with <FIG>, the second re-centering assembly includes a second driving mechanism <NUM> and a second movable seat <NUM>. The second driving mechanism <NUM> is fixed in the cavity of the parking platform, and the second driving mechanism <NUM> is electrically connected to the control board. The second movable seat <NUM> is embedded into the second elongated hole 11b and movably connected to the second driving mechanism <NUM>. Specifically, the second driving mechanism <NUM> includes a second driving motor <NUM>, a second driving wheel <NUM>, a second driven wheel <NUM>, a second timing belt <NUM>, and a second lead screw <NUM>. Both the second driving motor <NUM> and the second lead screw <NUM> are fixed to the main body of the parking platform, and the second lead screw <NUM> can rotate around its own axis. The second lead screw <NUM> is arranged alternately with the first lead screw <NUM> in the third direction Z. The second driving wheel <NUM> is fixed to the rotating shaft of the second driving motor <NUM>, the second driven wheel <NUM> is fixed to one end of the second lead screw <NUM>, and the second timing belt <NUM> is sleeved on the second driving wheel <NUM> and the second driven wheel <NUM>. The second lead screw <NUM> is provided with an external thread, the second movable seat <NUM> is provided with an internal thread adapted to the external thread, and the second movable seat <NUM> is threadedly connected to the second lead screw <NUM> so that in the second direction Y, the second driving mechanism <NUM> is configured to drive the second movable seat <NUM> to move relative to the parking plate <NUM>. Illustratively, the number of the second movable seats <NUM> is two, and one second movable seat <NUM> is embedded into one second elongated hole 11b. The internal threads of the two second movable seats <NUM> are opposite in rotational direction, and correspondingly, the second lead screw <NUM> is also provided with two external threads opposite in rotational direction. When the second driving motor <NUM> drives the second movable seat <NUM> to move, the two second movable seats <NUM> are close to each other or far away from each other due to the opposite thread rotational directions. In this way, the unmanned aerial vehicle can be parked on the parking plate <NUM> while the other two opposite sides of the unmanned aerial vehicle are acted on, in order to align the unmanned aerial vehicle's posture on the two opposite sides in the second direction Y. In addition, since the two second movable seats <NUM> share one driving mechanism, not only the manufacturing cost of the unmanned aerial vehicle parking device <NUM> can be saved, but also the space occupied by the second re-centering assembly can be saved, which is beneficial to the miniaturization of the unmanned aerial vehicle parking device <NUM>. It could be understood that the two second movable seats <NUM> may also be driven towards or away from each other by separate driving mechanisms, and the manner in which the driving mechanism drives the second movable seat <NUM> is not particularly limited by the present disclosure. For example, the driving mechanism may employ a motor gear rack structure or like structures capable of linear motion.

It should be noted that the re-centering position can be the center position of the parking platform or not, and the specific position can be set by technicians in the art according to the actual situation. Both the two first movable seats <NUM> and the two second movable seats <NUM> act on the landing gear of the unmanned aerial vehicle to realize the movement of the unmanned aerial vehicle from the parking position to the re-centering position. To this end, the first movable seat <NUM> and/or the second movable seat <NUM> may include a movable seat body <NUM> and a push rod <NUM>. The push rod <NUM> is connected to one end of the movable seat body <NUM> facing the centering position. When the unmanned aerial vehicle moves from the parking position to the re-centering position, the push rods <NUM> of the two first movable seats <NUM> respectively push the unmanned aerial vehicle from the two sides of the landing gear of the unmanned aerial vehicle at the same time under the driving of the first driving mechanism <NUM>, and the push rods <NUM> of the other two second movable seats <NUM> can respectively push the unmanned aerial vehicle from the other two sides of the landing gear of the unmanned aerial vehicle at the same time under the driving of the second driving mechanism <NUM>, thereby limiting the movement of the landing gear of the unmanned aerial vehicle. After the re-centering of the unmanned aerial vehicle is completed, both the first movable seat <NUM> and the second movable seat <NUM> can be reset.

With regard to the above-mentioned blocking assembly, reference is made to the example shown in <FIG> in conjunction with <FIG>. <FIG> is a schematic structural diagram of a driving rod in the first position in an unmanned aerial vehicle parking device <NUM> provided by an embodiment of the present disclosure. <FIG> is a schematic structural diagram of the driving rod in <FIG> in the second position. <FIG> is a schematic structural diagram of the driving rod in <FIG> in the third position. The blocking assembly comprises a driving rod <NUM>, a movable rod <NUM>, a stop bar <NUM>, and a stop block <NUM>. The driving rod <NUM> has a substantially elongated rod-like structure, one end of the driving rod <NUM> is fixed to the first movable seat <NUM>, and the driving rod <NUM> is movable among the first position, the second position, and the third position along with the movement of the first movable seat <NUM>. The other end of the driving rod <NUM> is provided with an avoidance notch (not shown). The movable rod <NUM> has a substantially L-shaped structure, and the movable rod <NUM> comprises a first support arm <NUM> and a second support arm <NUM> connected to the first support arm <NUM>. The first support arm <NUM> is rotatably connected to the other end of the driving rod <NUM>, and the end of the first support arm <NUM> away from one end of the second support arm <NUM> passes through and protrudes out of the avoidance notch; one end of the second support arm <NUM> away from the first support arm <NUM> is rotatably connected to the stop bar <NUM>, and the connection point of the stop bar <NUM> with the second support arm <NUM> is offset from the end of the stop bar <NUM> near one end of the second support arm <NUM>. The stop block <NUM> is fixed to the parking plate <NUM>, the stop block <NUM> has a first surface arranged adjacent to the parking plate <NUM> and a second surface arranged opposite to the parking plate <NUM>, the first surface is provided with a first blocking portion <NUM>, and the second surface is provided with a second blocking portion <NUM>. The movable rod <NUM> can be rotatably connected to the driving rod <NUM> through a torsion rotating shaft, which can provide a rotational force to the movable rod <NUM>. The stop bar <NUM> may also be rotatably connected to the movable rod <NUM> by means of another torsion rotating shaft, which can provide a rotational force for the stop bar <NUM>.

When the driving rod <NUM> is in the first position, the surface of the second support arm <NUM> facing the first support arm <NUM> abuts against the driving rod <NUM> under the rotational force of the torsion rotating shaft, and the end face of the stop bar <NUM> near one end of the second support arm <NUM> abuts against the parking plate <NUM> under the rotational force of the torsion rotating shaft, so that the stop bar <NUM> can be erected relative to the parking plate <NUM>, and the erected stop bar <NUM> can block the rotation of the blade of the unmanned aerial vehicle.

When the driving rod <NUM> is in the second position, the surface of the second support arm <NUM> facing the first support arm <NUM> always abuts against the driving rod <NUM> under the rotational force of the torsion rotating shaft. The surface of the stop bar <NUM> adjacent to the end face near one end of the second support arm <NUM> abuts against the first blocking portion <NUM> under the action of the driving force of the driving rod <NUM> and the rotational force of the torsion rotating shaft at the same time, so that the stop bar <NUM> can lie flat relative to the parking plate <NUM>, the lying stop bar <NUM> may not block the rotation of the blade of the unmanned aerial vehicle, and the projection of the stop bar <NUM> on the parking plate <NUM> partially overlaps with the parking plate <NUM> when it is viewed in the third direction Z.

When the driving rod <NUM> moves from the first position to the second position, an end portion of the stop bar <NUM> near one end of the second support arm <NUM> is blocked by the first blocking portion <NUM> of the stop block <NUM> to rotate in a direction near the second support arm <NUM> until the surface of the stop bar <NUM> adjacent to an end face near one end of the second support arm <NUM> abuts against the first blocking portion <NUM>, thereby converting the erected stop bar <NUM> into a lying stop bar <NUM>.

When the driving rod <NUM> is in the third position, the end portion of the first support arm <NUM> that extends out of one end of the avoidance notch is simultaneously subjected to the driving force of the driving rod <NUM> and the rotational force of the torsion rotating shaft to abut against the second blocking portion <NUM>. The surface of the stop bar <NUM> adjacent to the end face near one end of the second support arm <NUM> is always abutted against the second surface of the stop block <NUM> by the action of the driving force of the driving rod <NUM> and the rotational force of the torsion rotating shaft, and the projection of the stop bar <NUM> on the parking plate <NUM> completely overlaps with the parking plate <NUM> when it is viewed in the third direction Z.

When the driving rod <NUM> moves from the second position to the third position, the end portion of the first support arm <NUM> extending out of one end of the avoidance notch is blocked by the second blocking portion <NUM> of the stop block <NUM> to rotate in a direction close to the avoidance notch until the end portion of the first support arm <NUM> extending out of one end of the avoidance notch abuts against the second blocking portion <NUM>, thereby withdrawing the lying stop bar <NUM> into the parking platform.

In an embodiment of the present disclosure, an unmanned aerial vehicle parking on the parking plate <NUM> can be moved to the re-centering position by the cooperation of the first re-centering assembly and the second re-centering assembly. In addition, in the process of re-centering the unmanned aerial vehicle, the driving rod <NUM> in the blocking assembly is driven by the first re-centering assembly, and the stop bar <NUM> in the blocking assembly is converted from a lying state to an erecting state under the joint action of the driving rod <NUM>, the movable rod <NUM>, and the stop block <NUM>, thereby collapsing the blade of the unmanned aerial vehicle. When the unmanned aerial vehicle moves to the re-centering position, the first re-centering assembly and the second re-centering assembly are reset, and the stop bar <NUM> in the blocking assembly is converted from the erecting state to the lying state again under the combined action of the driving rod <NUM>, the movable rod <NUM>, and the stop block <NUM>, and is collapsed on the parking platform, so that the blade of the unmanned aerial vehicle is not blocked from rotating so as to ensure the normal take-off of the unmanned aerial vehicle. Furthermore, compared to other unmanned aerial vehicle parking devices <NUM>, the embodiment of the present disclosure requires fewer structures to achieve the collapsing of the blades of an unmanned aerial vehicle, and the structure of the unmanned aerial vehicle parking device <NUM> is more compact, facilitating the miniaturization of the unmanned aerial vehicle parking device <NUM>.

Further, the end portion of the first blocking portion of the stopping block <NUM> toward one end of the stop bar <NUM> is rounded off. In this way, the contacting portion between the stop bar <NUM> and the first blocking portion of the stopping block <NUM> is subjected to a relatively dispersed stress at the time of interference, which is beneficial to the structural stability of the stop bar <NUM> or the stopping block <NUM>.

It should be noted that when the first movable seat <NUM> drives the driving rod <NUM> to move in the first position, the second position, and the second position, and both are the positions where the two first movable seats <NUM> move the driving rod <NUM> away from each other under the drive of the first driving mechanism <NUM>.

In addition, an embodiment of the present disclosure is illustrated with a blocking assembly connected to either one of the two first movable seats <NUM>. It could be understood that the number of blocking assemblies may also be two, in which case one blocking assembly is connected to one first movable seat <NUM>. Of course, the number of blocking assemblies can also be four, in which case one blocking assembly is connected to any of the two first movable seats <NUM> and the two second movable seats <NUM>.

It could also be understood that the driving rod <NUM> may not be connected to the first movable seat <NUM>, i.e. the driving rod <NUM> may be driven by a separate driving mechanism, which may be a linear motor, a motor lead-screw structure, a gear rack structure, an electric push rod, an oil cylinder or like structures capable of the linear drive.

It could still be understood that the blocking assembly may also be provided without a moving piece, in which case the stop bar <NUM> is only driven to rotate by the driving rod <NUM> so that the stop bar <NUM> is switched between erecting and lying. Therefore, the blade of the unmanned aerial vehicle can also be collapsed without affecting the normal take-off of the unmanned aerial vehicle.

With continued reference to the example shown in <FIG>, the unmanned aerial vehicle parking device <NUM> may further comprise a charging interface <NUM>, the charging interface <NUM> being fixed to the first movable seat <NUM> and the charging interface <NUM> being electrically connected to the control board. Specifically, the number of charging interfaces <NUM> is two, and one charging interface <NUM> is fixed to one first movable seat <NUM>. The use of two charging interfaces <NUM> can ensure that when one of the charging interfaces <NUM> encounters a problem, charging can still be performed normally. The two charging interfaces <NUM> may also achieve a separate arrangement of a positive electrode and a negative electrode. Illustratively, the charging interface <NUM> is a charging pogo pin.

Please refer to the examples shown in <FIG> is a schematic structural diagram of another kind of unmanned aerial vehicle parking device <NUM> provided by an embodiment of the present disclosure. <FIG> is a schematic structural diagram of yet another kind of unmanned aerial vehicle parking device <NUM> provided by an embodiment of the present disclosure. The difference from the structure of the unmanned aerial vehicle parking device <NUM> shown in <FIG> is that the number of blocking assemblies in <FIG> is four, and the four blocking assemblies are all driven by respectively separate driving mechanisms. The difference between <FIG> is that the stop bars <NUM> of the four blocking assemblies are respectively in different fixed positions when they are moved to the first position. It should be noted that in embodiments of the present disclosure, the blades of the unmanned aerial vehicle are all non-foldable, i.e. when one blade on the same rotating shaft rotates, as shown in <FIG>, the other blade on the same rotating shaft also rotates along with it.

In <FIG>, when the stop bars <NUM> of the four blocking assemblies move to the first position, they are all located at one end of the unmanned aerial vehicle arm away from the fuselage, namely, they are located on the side close to the blade of the unmanned aerial vehicle. At this time, each blade of the unmanned aerial vehicle is arranged in parallel with the second direction. Compared with the parallel arrangement of the blades in the first direction after the unmanned aerial vehicle lands, this way of collapsing can reduce the area occupied by the blades and save the lateral space occupied by the unmanned aerial vehicle when the unmanned aerial vehicle is loaded on the unmanned aerial vehicle parking device <NUM>, thus reducing the volume required by the unmanned aerial vehicle parking device <NUM>.
