[0092] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present application. In addition, it should be understood that the specific implementation methods described herein are only used to illustrate and explain the present application, and are not used to limit the present application. In the present application, unless otherwise specified, the directional words used, such as "upper" and "lower", generally refer to the upper and lower parts of the device in actual use or working state, specifically the drawing direction in the accompanying drawings; and "inside" and "outside" refer to the outline of the device.

[0093] In related technologies, drone retraction devices can generally only fix a specific type of drone, and the clamping structure of the retraction device cannot be adjusted according to different types of drones, resulting in other types of drones being unable to be clamped and fixed after entering the retraction device. This needs further improvement.

[0094] To solve the above problems, refer to Figure 1 , the embodiment of the present application provides a retractable device 100 for retracting a drone 101, referring to Figure 1 The retractable device 100 includes a carrier assembly 1, a clamping assembly 2, and an adjustment assembly 3. The carrier assembly 1 is used to carry a drone 101. The clamping assembly 2 is movable relative to the carrier assembly 1 to clamp the drone 101 carried by the carrier assembly 1. The adjustment assembly 3 is used to adjust the relative position of the clamping assembly 2 and the carrier assembly 1, so that the clamping assembly 2 can clamp and secure drones 101 of different models. When different models of drones 101 are placed on the carrier assembly 1, the adjustment assembly 3 can flexibly adjust the relative position of the clamping assembly 2 and the carrier assembly 1 according to the specific model of the drone 101, allowing drones 101 of different models to be clamped and secured, effectively improving the versatility and practicality of the retractable device 100.

[0095] In this embodiment, the number of clamping assemblies 2 is not limited, and can be one, two, or more than one. The type of adjustment assembly 3 is not limited, and can be a motor assembly, a cylinder assembly, an oil cylinder assembly, a screw assembly, or other types of adjustment assemblies. The adjustment assembly 3 can directly adjust the relative position of the clamping assembly 2 and the object carrier assembly 1, or it can indirectly adjust the relative position of the clamping assembly 2 and the object carrier assembly 1, without limitation.

[0096] Exemplarily, the number of the clamping assembly 2 is one, and the clamping assembly 2 includes a fixed block (not shown in the figure) and a clamping block (not shown in the figure) that are fixedly connected. The carrying assembly 1 is provided with a baffle (not shown in the figure), and the adjustment assembly 3 includes a linear motor (not shown in the figure). The output shaft of the linear motor is transmission-connected to the fixed block. When the drone 101 is located between the baffle and the clamping block, the linear motor can drive the fixed block and the clamping block to move toward the baffle. During the movement of the clamping block, the drone 101 can be pushed to move and the drone 101 can be clamped and fixed between the baffle and the clamping block. The linear motor can adjust the relative position of the clamping block and the baffle according to the model of the drone 101, so that the clamping block can fix drones 101 of different models.

[0097] In another exemplary embodiment, the clamping assembly 2 includes a first clamping block (not shown in the figure) and a second clamping block (not shown in the figure) that are relatively arranged, and the adjusting assembly 3 includes a first cylinder assembly (not shown in the figure) and a second cylinder assembly (not shown in the figure). The first clamping block is transmission-connected to the first cylinder assembly, and the second clamping block is transmission-connected to the second cylinder assembly. When the drone 101 is located between the first clamping block and the second clamping block, the first cylinder assembly and the second cylinder assembly respectively push the first clamping block and the second clamping block toward the drone 101, so that the first clamping block and the second clamping block clamp the drone 101. The first cylinder assembly and the second cylinder assembly can adjust the relative positions of the first clamping block and the second clamping block and the object-carrying assembly 1 according to the model of the drone 101, so that the first clamping block and the second clamping block can fix drones 101 of different models.

[0098] In one embodiment, the adjustment component 3 is used to adjust the travel of the clamping component 2 so that the position of the clamping component 2 relative to the object-carrying component 1 in the clamping state can be adjusted. The clamping state refers to the state in which the drone 101 is clamped and fixed by the clamping component 2. For example, when it is necessary to fix a first drone 101 of a first model, the adjustment component 3 can adjust the movable stroke of the clamping component 2 according to the model of the first drone 101, so that the clamping component 2 clamps and fixes the first drone 101, and at this time the clamping component 2 is in the first position relative to the carrier component 1 in the clamping state; when it is necessary to fix a second drone 101 of a second model, the adjustment component 3 can adjust the movable stroke of the clamping component 2 according to the model of the second drone 101, so that the clamping component 2 clamps and fixes the second drone 101, and at this time the clamping component 2 is in the second position relative to the carrier component 1 in the clamping state; in this way, the adjustment component 3 can adjust the movable stroke of the clamping component 2 according to the model of the drone 101, so that the position of the clamping component 2 relative to the carrier component 1 in the clamping state is adjustable, and the clamping component 2 can flexibly adapt to drones 101 of different models, thereby improving the versatility of the retracting and unfolding device 100.

[0099] In this embodiment, the adjustment component 3 can adjust the starting point and end point of the active travel of the clamping component 2, and can also adjust the trajectory of the active travel of the clamping component 2, which is not limited here. For example, the adjustment component 3 can cause the clamping component 2 to move from the starting point 1 along a straight trajectory to the end point 1 to clamp and secure the drone 100; for another example, the adjustment component 3 can cause the clamping component 2 to move from the starting point 2 along an S-shaped trajectory to the end point 1 to clamp and secure the drone 100.

[0100] In one embodiment, reference Figure 2 The clamping assembly 2 includes a first clamping member 21 and a second clamping member 22. The first clamping member 21 and the second clamping member 22 can move relative to each other to cooperate in clamping and securing the drone 101 carried by the load-carrying assembly 1. The adjustment assembly 3 is used to adjust the travel of at least one of the first clamping member 21 and the second clamping member 22. For example, the adjustment assembly 3 is used to adjust the travel of the first clamping member 21; for another example, the adjustment assembly 3 is used to adjust the travel of the second clamping member 22; for another example, the adjustment assembly 3 is used to adjust the travel of both the first clamping member 21 and the second clamping member 22. In this embodiment, the relative movement of the two clamping members allows for flexible adjustment of the clamping distance between the first clamping member 21 and the second clamping member 22. The first clamping member 21 and the second clamping member 22 are compatible with a variety of different drone models 101, thereby improving the versatility of the retractable device 100. In addition, for drones 101 with asymmetric fuselages or special layouts, the position of individual clamping members can be independently adjusted to achieve precise fixation. In this embodiment, the number of the first clamping member 21 and the second clamping member 22 is not limited. The first clamping member 21 may be one, two, or more than two; the second clamping member 22 may be one, two, or more than two.

[0101] In one embodiment, reference Figure 3The retracting and unfolding device 100 further includes a first drive assembly 4, and at least one of the first clamping member 21 and the second clamping member 22 is connected to the first drive assembly 4, so that the first drive assembly 4 can drive the first clamping member 21 and the second clamping member 22 to move relative to each other, so as to clamp and fix the drone 101 carried by the carrier assembly 1. For example, the first clamping member 21 is connected to the first drive assembly 4, and the first drive assembly 4 can drive the first clamping member 21 to move in a direction close to the second clamping member 22; for another example, the second clamping member 22 is connected to the first drive assembly 4, and the first drive assembly 4 can drive the second clamping member 22 to move in a direction close to the first clamping member 21; for another example, both the first clamping member 21 and the second clamping member 22 are connected to the first drive assembly 4, and the first drive assembly 4 can drive the first clamping member 21 and the second clamping member 22 to move closer to each other, so as to clamp and fix the drone 101 carried by the carrier assembly 1. The first drive assembly 4 can precisely control the travel of the first clamping member 21 and / or the second clamping member 22, ensuring that the drone 101 is quickly and securely secured to the payload assembly 1. In this embodiment, the type of the first drive assembly 4 is not limited and can be a motor assembly, a cylinder assembly, an oil cylinder assembly, a screw assembly, or other types of drive assemblies.

[0102] In one embodiment, reference Figure 3 and Figure 4 The first drive assembly 4 includes a first fluid-containing component 41 having a deformable first fluid chamber. When the first fluid chamber expands, it can drive at least one of the first clamping member 21 and the second clamping member 22 to move relative to the carrier assembly 1. The force generated by the first fluid-containing component 41 during expansion is gradual, reducing local stress concentration caused by rigid contact between the first fluid-containing component 41 and other components. Furthermore, the first fluid-containing component 41 can adapt to various contact surfaces by adjusting its internal pressure, providing greater flexibility. In this embodiment, the expansion of the first fluid chamber can directly drive the first clamping member 21 and / or the second clamping member 22 to move relative to the carrier assembly 1, or indirectly. The type of the first fluid-containing component 41 is not limited; it can be an airbag, a water bag, or other fluid-containing component. Preferably, the first fluid-containing component 41 is an airbag, which can reduce the weight of the retractable device 100.

[0103] Exemplarily, the first drive assembly 4 includes an airbag (not shown in the figure) and a push rod (not shown in the figure). The airbag and the push rod are arranged adjacent to each other, and the push rod is fixedly connected to the first clamping member 21. When the airbag expands in volume, it can push the push rod and the first clamping member 21 to move toward the second clamping member 22 to cooperate with the second clamping member 22 to clamp the drone 101.

[0104] As another example, the first drive assembly 4 includes a first water bag (not shown) and a second water bag (not shown). The first water bag is disposed adjacent to the first clamping member 21, and the second water bag is disposed adjacent to the second clamping member 22. When the first water bag expands, it can contact the first clamping member 21 and push the first clamping member 21 toward the drone 101. When the second water bag expands, it can contact the second clamping member 22 and push the second clamping member 22 toward the drone 101. The first clamping member 21 and the second clamping member 22 cooperate with each other to clamp and secure the drone 101.

[0105] In one embodiment, reference Figure 3 and Figure 4 The first drive assembly 4 also includes a movable component 42 and at least one flexible connector 1343. The movable component 42 is movably disposed on the carrier assembly 1. When the volume of the first fluid chamber expands, it can drive the movable component 42 to move. At least one of the first clamping member 21 and the second clamping member 22 is connected to the movable component 42 via the flexible connector 1343, so that the movable component 42 can pull the corresponding first clamping member 21 or second clamping member 22 to move. The flexible connector 1343 can change the transmission direction, allowing the first fluid containing member 41 and the movable component 42 to be arranged away from the clamping area. The flexible connector 1343 can also be deformed to adapt to irregular spaces, thereby increasing the flexibility of the structural layout of the retractable device 100. In this embodiment, the type of flexible connector 1343 is not limited. The flexible connector 1343 can include a rope, a Bowden cable, a chain, a hose, or other types of flexible connectors 13.

[0106] In one embodiment, reference Figure 3 and Figure 4The first drive assembly 4 also includes a second fluid-containing component 44. The second fluid-containing component 44 is provided with a deformable second fluid chamber that communicates with the first fluid chamber. At least a portion of the fluid in the second fluid chamber can flow into the first fluid chamber, causing the first fluid chamber to expand. The second fluid chamber communicates with the first fluid chamber and can supply fluid to the first fluid chamber, causing the first fluid chamber to expand and thereby drive the movement of the first and second clamping members 21 and 22. Fluid in the first fluid chamber can also flow back into the second fluid chamber, causing the first fluid chamber to decrease in volume and thereby releasing the driving force on the first and second clamping members 21 and 22. In this embodiment, the force generated by the volume expansion of the second fluid-containing component 44 is gradual, reducing local stress concentration caused by rigid contact between the second fluid-containing component 44 and other components. Furthermore, the second fluid-containing component 44 can adapt to various contact surface shapes by adjusting its internal pressure, providing greater flexibility. The type of the second fluid-containing component 44 is not limited and can be an air bag, a water bag, or other fluid-containing component. Preferably, the second fluid containing component 44 is an airbag, which can reduce the weight of the retractable device 100 .

[0107] In one embodiment, reference Figure 3 and Figure 4 The first fluid containing component 41 is a first air tube, the second fluid containing component 44 is a first airbag, the first airbag is connected to the first air tube, the flexible connector 1343 includes a first rope 431 and a second rope 432, the movable component 42 includes a first movable component and a second movable component, the carrier assembly 1 includes a carrier plate 11 and a mounting seat 12, the carrier plate 11 is fixed on the mounting seat 12, the drone 101 is placed on the carrier plate 11, and the mounting seat 12 includes a first accommodating cavity 121 and a second accommodating cavity 122 arranged in sequence along the direction of gravity, a partition 123 is provided between the first accommodating cavity 121 and the second accommodating cavity 122, and a limiting hole 124 is provided on the partition 123; At least part of the first clamping member 21 and at least part of the second clamping member 22 are movably arranged in the first accommodating cavity 121, and the first clamping member 21 and the second clamping member 22 are distributed on opposite sides of the limiting hole 124 along the first direction, the first direction is the left and right direction, and the left and right directions are perpendicular to the direction of gravity; the first movable component, the first air pipe and the second movable component are arranged in sequence in the left and right directions in the second accommodating cavity 122; one end of the first rope 431 is connected to the first clamping member 21, and the other end passes through the limiting hole 124 and is connected to the first movable component; one end of the second rope 432 is connected to the second clamping member 22, and the other end passes through the limiting hole 124 and is connected to the second movable component.

[0108] In this embodiment, when the first airbag supplies air to the first air tube, the first air tube expands and can extend leftward and rightward. The left and right sides of the first air tube respectively abut the first movable member and the second movable member. The first air tube pushes the first movable member to the left, while simultaneously pushing the second movable member to the right. When the first movable member moves, it pulls the first rope 431, which drives the first clamping member 21 toward the limiting hole 124. When the second movable member moves, it pulls the second rope 432, which drives the second clamping member 22 toward the limiting hole 124, thereby adjusting the distance between the first clamping member 21 and the second clamping member 22. In this embodiment, the amount of air supplied by the first airbag to the first air tube can be adjusted according to the model of the drone 101 to control the volume expansion of the first air tube, thereby controlling the movement stroke of the first movable component and the second movable component. By controlling the movement stroke of the first movable component and the second movable component, the distance between the first clamping member 21 and the second clamping member 22 can be adjusted, so that the first clamping member 21 and the second clamping member 22 can clamp and fix drones 101 of different models.

[0109] In one embodiment, the retractable device 100 further includes a housing 5, within which the payload assembly 1 is movably mounted. The payload assembly 1 can be driven by the gravity of the drone 101 to move relative to the housing 5, thereby driving the volume expansion of the first fluid chamber. In this embodiment, utilizing the gravity of the drone 101 to drive the volume expansion of the first fluid chamber eliminates the need for external energy, conserving energy and reducing the risk of circuit failure. In this embodiment, the payload assembly 1 can directly or indirectly drive the volume expansion of the first fluid chamber, without limitation.

[0110] In one embodiment, the retractable device 100 further includes a first stopper 6, and the payload assembly 1 has a second stopper (not shown) that cooperates with the first stopper 6. When the payload assembly 1 moves to a predetermined position under the force of gravity of the drone 101, the first stopper 6 and the second stopper engage with each other, securing the payload assembly 1 within the housing 5. The first stopper 6 and the second stopper secure the payload assembly 1, preventing the payload assembly 1 and the drone 101 from shaking relative to the housing 5, thereby improving the stability of the payload assembly 1 and the drone 101.

[0111] Exemplarily, the first limiting portion 6 is a pin arranged at the bottom of the shell 5, and the second limiting portion is a slot arranged at the bottom of the carrier component 1. When the carrier component 1 moves downward to a preset position relative to the shell 5 under the action of the gravity of the drone 101, the pin can be inserted into the slot to limit and fix the carrier component 1.

[0112] Another exemplary reference Figure 3 and Figure 4 The first limiting portion 6 includes a spring 61 and an insert 62. One end of the spring 61 is fixedly connected to the side wall of the housing 5, and the other end is fixedly connected to the insert 62. A first guiding slope is provided on the upper surface of the insert 62. The second limiting portion is a slot provided on the side wall of the carrier assembly 1. As the carrier assembly 1 moves downward relative to the housing 5 under the action of the gravity of the drone 101, it can interfere with the insert 62 and compress the first guiding slope of the insert 62. The first guiding slope causes the insert 62 to move toward the side wall of the housing 5 under the action of the first guiding slope, which compresses the spring 61. When the slot of the carrier assembly 1 is aligned with the insert 62, the carrier assembly 1 releases its compressive action on the insert 62. The insert 62 can then move away from the side wall of the housing 5 under the action of the spring 61 and be inserted into the socket, thereby securing the carrier assembly 1. Preferably, an electromagnetic locking mechanism (not shown in the figure) is also provided on the shell 5, and the electromagnetic locking mechanism is electrically connected to the vehicle ignition system. When the vehicle is driving, the vehicle ignition system energizes the electromagnetic locking mechanism, so that the electromagnetic locking mechanism locks the plug 62 in the slot, to prevent the sudden violent vibration during the driving of the vehicle from causing the plug 62 to accidentally detach from the carrier component 1, resulting in the carrier component 1 being not firmly fixed and the drone 101 being shaken and damaged; after parking, the electromagnetic locking mechanism is powered off and automatically releases the locking effect on the plug 62, and the plug 62 can leave the slot to release the fixing effect on the carrier component 1.

[0113] In this embodiment, a second guiding slope is provided on the lower surface of the insert block 62. The inclination of the second guiding slope is smaller than that of the first guiding slope, which can enhance the limiting effect of the second guiding slope on the slot. The slot is not likely to slide along the second guiding slope to leave the insert block, and the slot is not likely to escape from the limit of the insert block due to bumps.

[0114] In one embodiment, the retractable device 100 further includes an extrusion member 7. Movement of the extrusion member 7 can drive the first fluid chamber to expand. The payload assembly 1 can be driven by the gravity of the drone 101 to drive the extrusion member 7. This movement of the extrusion member 7 does not require an external power source, thus saving energy. The payload assembly 1 is driven by the gravity of the drone 101 to drive the extrusion member 7 to move and expand the first fluid chamber, thereby driving the first clamping member 21 and the second clamping member 22 to undergo a first movement relative to the payload assembly 1. If the first clamping member 21 and the second clamping member 22 are able to clamp the drone 101 after the first movement, no further adjustment of the first clamping member 21 and the second clamping member 22 is required. If the first clamping member 21 and the second clamping member 22 are unable to clamp the drone 101 after the first movement, the adjustment assembly 3 can drive the extrusion member 7 to move relative to the housing 5, driving the first fluid chamber to further expand, causing the first clamping member 21 and the second clamping member 22 to undergo a second movement relative to the payload assembly 1 to clamp and secure the drone 101. The adjustment assembly 3 adjusts the maximum travel position of the extrusion member 7 to ensure that the first clamping member 21 and the second clamping member 22 can move to the preset position and clamp the drone 101, thereby improving the clamping and fixing effect. In this embodiment, the maximum travel position refers to the final position of the extrusion member 7 when the first clamping member 21 and the second clamping member 22 clamp the drone 101. In this embodiment, the movement of the extrusion member 7 can directly drive the expansion of the first fluid chamber volume, or it can indirectly drive the expansion of the first fluid chamber volume, which is not limited here.

[0115] In one embodiment, the adjustment assembly 3 includes a transmission member 31 and a drive member 32. The transmission member 31 is fixedly connected to the extrusion member 7 and is also movably connected to the carrier assembly 1, allowing the carrier assembly 1 to drive the extrusion member 7 to move via the transmission member 31. The drive member 32 is in transmission connection with the transmission member 31, driving the transmission member 31 to drive the extrusion member 7 relative to the carrier assembly 1. In this embodiment, the drive member 32 drives the transmission member 31 to move the extrusion member 7 relative to the carrier assembly 1. This can drive the movement of the extrusion member 7 according to the model of the drone 101, causing the first clamping member 21 and the second clamping member 22 to move relative to the carrier assembly 1 to clamp and secure drones 101 of different models, thereby improving the mobility of the first clamping member 21 and the second clamping member 22. In this embodiment, the transmission member 31 can be rotationally connected to the carrier assembly 1, or it can be slidingly connected to the carrier assembly 1, without limitation. The drive member 32 can be a motor, a pneumatic cylinder, an oil cylinder, or other types of drive members 32, without limitation.

[0116] In a specific embodiment, the retracting and unfolding device 100 includes a first airbag, a first rope 431, a second rope 432, a first movable part, and a second movable part; the first fluid containing part 41 is a first air tube, and the first airbag is connected to the first air tube; the carrier assembly 1 includes a connector 13, a carrier plate 11 and a mounting seat 12, the carrier plate 11 and the connector 13 are both fixed on the mounting seat 12, and the drone 101 is placed on the carrier plate 11; the transmission part 31 is a threaded rod, and the threaded rod is threadedly connected to the connector 13; the driving part 32 is a rotating rod, the threaded rod is fixedly connected to the rotating rod, and the extrusion part 7 is fixedly connected to the threaded rod. The mounting base 12 includes a first accommodating cavity 121 and a second accommodating cavity 122 arranged in sequence along the direction of gravity, a partition 123 is provided between the first accommodating cavity 121 and the second accommodating cavity 122, and a limiting hole 124 is provided on the partition 123; at least part of the first clamping member 21 and at least part of the second clamping member 22 are movably arranged in the first accommodating cavity 121, and the first clamping member 21 and the second clamping member 22 are distributed on opposite sides of the limiting hole 124 along the first direction, the first direction is the left and right direction, and the left and right directions are perpendicular to the direction of gravity; the first movable component, the first air pipe and the second movable component are arranged in sequence in the second accommodating cavity 122 along the left and right directions; one end of the first rope 431 is connected to the first clamping member 21, and the other end is connected to the first movable component after passing through the limiting hole 124; one end of the second rope 432 is connected to the second clamping member 22, and the other end is connected to the second movable component after passing through the limiting hole 124.

[0117] In this embodiment, the load-carrying assembly 1 can be driven by the gravity of the drone 101 to move the connector 13, the threaded rod, and the extrusion member 7 toward the first airbag to a preset position. The extrusion member 7 squeezes the first airbag so that the gas in the first airbag enters the first air tube. When the first air tube expands in volume, it can extend in the left and right directions. The left side of the first air tube abuts against the first movable part and pushes the first movable part to move to the left. When the first movable part moves, it pulls the first rope 431. Driven by the first rope 431, the first clamping member 21 moves from position P10 to position P11 in the direction close to the limiting hole 124. The movement distance of the first clamping member 21 is L10. The right side of the first air tube abuts against the second movable part and pushes the second movable part to move to the right. When the second movable part moves, it pulls the second rope 432. Driven by the second rope 432, the second clamping member 22 moves from position P20 to position P11 in the direction close to the limiting hole 124. 21, the moving distance of the second clamping member 22 is L20; when the first clamping member 21 at position P11 and the second clamping member 22 at position P21 cannot clamp the fixed drone 101 due to the large distance between them, the rotating rod can drive the threaded rod to move relative to the connection, and when the threaded rod moves, it can drive the extrusion member 7 to move toward the first airbag to further squeeze the first airbag, and more gas in the first airbag is squeezed into the first air tube, causing the first air tube to further expand in volume, until the first clamping member 21 and the second clamping member 22 can cooperate with each other to clamp the drone 101, and then stop driving the extrusion member 7 to move. After the first air tube further expands, it can push the first movable component further to the left. As the first movable component moves, it pulls the first rope 431. Driven by the first rope 431, the first clamping member 21 moves from position P11 to position P12 in a direction close to the limiting hole 124. The distance the first clamping member 21 moves from position P11 to position P12 is L11. The first air tube pushes the second movable component further to the right. As the second movable component moves, it pulls the second rope 432. Driven by the second rope 432, the second clamping member 22 moves from position P21 to position P22 in a direction close to the limiting hole 124. The distance the second clamping member 22 moves from position P21 to position P22 is L21. In this way, the adjustment component 3 adjusts the travel of the first clamping member 21 and the second clamping member 22 for a specific model of drone 101 to compensate for the position.

[0118] In this embodiment, when the first clamping member 21 and the second clamping member 22 clamp the drone 101, the clamping force of the first clamping member 21 and the second clamping member 22 on the drone 101 can be further adjusted by controlling the rotation speed and rotation time of the rotating rod.

[0119] In this embodiment, when the object-carrying assembly 1 drives the extrusion member 7 to move away from the first airbag under the action of an external force, the degree of compression of the first airbag by the extrusion member 7 is reduced, causing some of the gas in the first air tube to flow back into the first airbag, the volume of the first air tube to decrease, and the driving force exerted by the first air tube on the first movable part and the second movable part to decrease, thereby reducing the tension applied by the first movable part to the first clamping member 21 and the tension applied by the second movable part to the second clamping member 22. Under the action of a reset member (not shown in the figure), the first clamping member 21 can move a distance L10 away from the limiting hole 124, and the second clamping member 22 can move a distance L20 away from the limiting hole 124 under the action of the reset member to release the clamping of the drone 101. Afterwards, for the same model of drone 101, the gravity of the drone 101 can be used to drive the carrier assembly 1 to drive the connector 13, the threaded rod, and the extrusion member 7 to move toward the first airbag, so that the first clamping member 21 moves a distance L10 in the direction of approaching the limiting hole 124 to return to position P12, and the second clamping member 22 moves a distance L20 in the direction of approaching the limiting hole 124 to return to position P22, thereby automatically clamping and fixing the same model of drone 101. Through this mechanical process, the retractable device 100 can achieve the same clamping process and clamping effect for the same model of drone 101 each time, without having to readjust the movable travel of the first clamping member 21 and the second clamping member 22 through the adjustment assembly 3 each time, thereby simplifying the use steps of the retractable device 100.

[0120] In one embodiment, one end of the driving member 32 is exposed on the surface of the housing 5 to receive the external force of the retractable device 100 to drive the transmission member 31. The one end of the driving member 32 is exposed on the surface of the housing 5, which makes it easy for the user to apply force to the driving member 32.

[0121] In one embodiment, reference Figure 5 The retractable device 100 further includes a first detection component and a control module. The first detection component is configured to detect first predetermined information about the drone 101 carried by the payload assembly 1. The control module is configured to control the movement of the driver 32 based on the first predetermined information to adjust the relative position of the extrusion member 7 and the payload assembly 1. In this embodiment, the control module controls the movement of the driver 32 based on the first predetermined information, allowing the retractable device 100 to automatically adjust the travel range of the first and second clamping members 21 and 22 without manual intervention, thereby improving the automation level and adjustment accuracy of the retractable device 100.

[0122] In one embodiment, the first preset information includes the contact point distribution and pressure value of the drone 101 on the carrier assembly 1. The control module is configured to determine the target clamping distance between the first clamping member 21 and the second clamping member 22 based on the first preset information, and control the movement of the driving member 32 based on the target clamping distance, so that the extrusion member 7 moves from the first position to the second position relative to the carrier assembly 1. In this embodiment, when the extrusion member 7 moves from the first position to the second position relative to the carrier assembly 1, the movement of the extrusion member 7 can drive the volume of the first fluid cavity to expand, and the expansion of the first fluid cavity volume can drive the first clamping member 21 and / or the second clamping member 22 to move relative to the carrier assembly 1, so that the clamping distance between the first clamping member 21 and the second clamping member 22 is the target clamping distance. The clamping distance between the first clamping member 21 and the second clamping member 22 is adjusted according to the contact point distribution and pressure value of the drone 101 on the carrier assembly 1 to improve the accuracy of the retracting device 100 in clamping and fixing the drone 101, and to reduce the situation where the clamping force of the first clamping member 21 and the second clamping member 22 is insufficient or excessive.

[0123] In one embodiment, the first detection component includes a pressure sensor array, which is disposed on the surface of the carrier assembly 1 and is used to detect the contact point distribution and pressure value of the drone 101 on the surface of the carrier assembly 1 .

[0124] In one embodiment, the retracting and unfolding device 100 further includes a reset component, which is electrically connected to the control module. When the reset component is activated, the control module can control the driving member 32 to drive the transmission member 31 and the extrusion member 7 to move, so that the extrusion member 7 moves from the second position to the first position relative to the carrier component 1, so as to facilitate the adjustment component 3 to readjust the stroke position of the extrusion member 7 according to different models of drones 101, and prepare for the next matching of different models of drones 101.

[0125] In one embodiment, the reset component is configured to receive a pressing operation from the user. The user can press the reset component to activate the reset component as needed, and the activation of the reset component is not subject to time constraints, which is highly flexible.

[0126] In one embodiment, reference Figure 1 The retractable device 100 further includes a cover 8, which can activate the reset component when the cover 8 opens the housing 5. The reset component is automatically activated by the cover opening operation, and there is no need to manually press the reset component, which can improve the convenience of the reset operation.

[0127] In this embodiment, a sensor may be provided on the cover 8. When the sensor detects that the cover 8 is opened, the sensor sends a signal to the control module, and the control module activates the reset component.

[0128] In one embodiment, reference Figure 6The retracting and unfolding device 100 also includes a wireless communication module, which is used to communicate with the drone 101 carried by the carrier assembly 1 to obtain the second preset information of the drone 101; the control module is configured to determine the target clamping position of the first clamping member 21 and the second clamping member 22 based on the second preset information, and control the movement of the driving member 32 to adjust the relative position of the extrusion member 7 and the carrier assembly 1, so that the first clamping member 21 and the second clamping member 22 move to the target clamping position, thereby improving the accuracy and intelligence of the retracting and unfolding device 100 in clamping and fixing the drone 101, and reducing the situation where the clamping force of the first clamping member 21 and the second clamping member 22 is insufficient or excessive. In this embodiment, the wireless communication module can be a Bluetooth module or a WIFI module, which is not limited here. The second preset information can include the model information of the drone 101 such as size and weight in the wireless radio frequency identification chip, which is not limited here.

[0129] In one embodiment, after the driving member 32 is controlled to move based on the target clamping distance so that the extrusion member 7 moves from the first position to the second position relative to the carrier assembly 1 , the driving member 32 is powered off to save energy consumption of the driving member 32 .

[0130] In one embodiment, reference Figure 7 The retractable device 100 further includes a second detection component for detecting the pressure value in the first fluid chamber; and a control module configured to control the movement of the driver 32 based on the pressure value to adjust the relative position of the extrusion member 7 and the carrier assembly 1. In this embodiment, the control module calculates the target clamping positions of the first clamping member 21 and the second clamping member 22 based on the pressure value and controls the movement of the driver 32 to adjust the relative positions of the extrusion member 7 and the carrier assembly 1, so that the first clamping member 21 and the second clamping member 22 move to the target clamping positions, thereby improving the accuracy and intelligence of the retractable device 100 in clamping and securing the drone 101.

[0131] In this embodiment, the second detecting component may directly detect the pressure value of the first fluid chamber, or may indirectly detect the pressure value of the first fluid chamber, which is not limited here.

[0132] Exemplarily, the second detection component is a digital pressure sensor, and the retracting device 100 also includes a PID adjustment unit, which establishes a mathematical model between the displacement of the first clamping member 21 and the second clamping member 22 and the pressure value of the first fluid chamber. The target clamping position of the first clamping member 21 and the second clamping member 22 is determined according to the pressure value of the first fluid chamber, and the movement of the driving member 32 is controlled to adjust the relative position of the extrusion member 7 and the object-carrying component 1, so that the first clamping member 21 and the second clamping member 22 move to the target clamping position.

[0133] In one embodiment, the retractable device 100 further includes a pressure relief member (not shown in the figure), which has an exhaust port, and the first fluid chamber can be connected to the external atmosphere through the exhaust port; when the pressure in the first fluid chamber is too high, the fluid in the first fluid chamber can be discharged through the pressure relief member.

[0134] In one embodiment, the control module is configured to control the pressure relief element to open the exhaust port when the pressure exceeds a preset pressure value, thereby allowing the gas in the first fluid chamber to be discharged through the exhaust port, thereby preventing excessive pressure in the first fluid chamber and improving the safety of the retractable device 100. In this embodiment, the pressure relief element can be a gravity-type pressure relief valve or a solenoid valve, which is not limited here.

[0135] In one embodiment, the retractable device 100 further includes an alarm component, which is electrically connected to the second detection component. When the second detection component detects that the pressure in the first fluid chamber is greater than a preset pressure value, the alarm component sounds an alarm to alert the user.

[0136] In one embodiment, reference Figure 1 The first driving component 4 also includes a first elastic member 45, which is installed on the carrier component 1. The first elastic member 45 is used to drive the first clamping member 21 to move to release the clamping of the drone 101, so that the drone 101 can be separated from the carrier component 1.

[0137] In one embodiment, one end of the first elastic member 45 is fixedly connected to the carrier assembly 1, and the other end is fixedly connected to the first clamping member 21. When the first clamping member 21 moves toward the drone 101, the first clamping member 21 stretches the first elastic member 45. When the clamping of the drone 101 needs to be released, the first elastic member 45 recovers its elastic deformation and drives the first clamping member 21 away from the drone 101, thereby releasing the drone 101.

[0138] In one embodiment, reference Figure 1 The first driving component 4 also includes a second elastic member 46, which is installed on the carrier component 1. The second elastic member 46 is used to drive the second clamping member 22 to move to release the clamping of the drone 101, so that the drone 101 can be separated from the carrier component 1.

[0139] In one embodiment, one end of the second elastic member 46 is fixedly connected to the carrier assembly 1, and the other end is fixedly connected to the second clamping member 22. When the second clamping member 22 moves toward the drone 101, the second clamping member 22 stretches the second elastic member 46. When the drone 101 needs to be released, the second elastic member 46 recovers its elastic deformation and drives the second clamping member 22 away from the drone 101, thereby releasing the drone 101.

[0140] In one embodiment, at least one of the first clamping member 21 and the second clamping member 22 is slidably connected to the carrier assembly 1. The sliding connection can make the movement of the first clamping member 21 and / or the second clamping member 22 more stable.

[0141] In a specific embodiment, the carrier assembly 1 is provided with a first guide member, and the first clamping member 21 is provided with a second guide member that cooperates with the first guide member. The first clamping member 21 slides along the first guide member relative to the carrier assembly 1. The structures of the first guide member and the second guide member are not limited; one of the first guide member and the second guide member may be a slide rail, and the other may be a slide groove that cooperates with the slide rail.

[0142] In a specific embodiment, the carrier assembly 1 is provided with a third guide member, and the second clamping member 22 is provided with a fourth guide member that cooperates with the third guide member. The second clamping member 22 slides along the third guide member relative to the carrier assembly 1. The structures of the third and fourth guide members are not limited; one of the third and fourth guide members may be a slide rail, and the other may be a slide groove that cooperates with the slide rail.

[0143] In one embodiment, reference Figure 2 The retractable device 100 also includes a housing 5, a cover 8, and a second drive assembly 9. The housing 5 houses the carrier assembly 1 and has an opening for accessing the drone 101 through the opening. The cover 8 is used to open or close the opening. The second drive assembly 9 is connected to the cover 8 and is used to drive the cover 8 to open or close the opening. The second drive assembly 9 drives the cover 8 to open the opening, allowing the drone 101 to exit the retractable device 100 through the opening. The second drive assembly 9 drives the cover 8 to close the opening, thereby better protecting the drone 101 within the retractable device 100.

[0144] In one embodiment, to improve the sealing effect of the cover 8 on the opening, a sealable strip (not shown) can be provided on the edge of the cover 8, thereby improving the sealing effect of the retractable device 100. The type of the seal strip is not limited, and the seal strip can be an inflatable seal strip or a silicone seal strip.

[0145] In one embodiment, the second drive assembly 9 includes a telescopic rod assembly 91 and a third fluid-containing component 92. The telescopic rod assembly 91 includes a fixed section 911 and a movable section 912, which are movably connected. The fixed section 911 is fixedly connected to the housing 5, and the movable section 912 is fixedly connected to the lid 8. The third fluid-containing component 92 has a deformable third fluid chamber. When the volume of the third fluid chamber decreases, it can drive the movable section 912 to retract or fold relative to the fixed section 911, thereby driving the lid 8 to close the opening. The telescopic rod assembly 91 is used to connect the lid 8 and the housing 5. When the opening is closed, the movable section 912 retracts or folds relative to the fixed section 911, which saves space occupied by the telescopic rod assembly 91 when the lid 8 is closed. The third fluid-containing component 92 can deform and adapt to different contact surface shapes by adjusting its internal pressure, providing greater flexibility. In this embodiment, when the volume of the third fluid chamber decreases, it can directly or indirectly drive the movable section 912 to retract or fold relative to the fixed section 911. The type of the third fluid holding component 92 is not limited. The third fluid holding component 92 can be an air bag, a water bag, or other holding components capable of holding fluid. Preferably, the third fluid holding component 92 is an air bag, which can reduce the weight of the retractable device 100.

[0146] In one embodiment, the second drive assembly 9 further includes a fourth fluid-containing component 93. The fourth fluid-containing component 93 includes a deformable fourth fluid chamber that communicates with the third fluid chamber. At least a portion of the fluid in the third fluid chamber can flow into the fourth fluid chamber, reducing the volume of the third fluid chamber. The deformable fourth fluid-containing component 93 can adapt to various mounting cavities by adjusting its internal pressure, providing greater flexibility. The type of the fourth fluid-containing component 93 is not limited; it can be an airbag, a water bag, or other fluid-containing component. Preferably, the fourth fluid-containing component 93 is an airbag, which can reduce the weight of the retractable device 100.

[0147] In one embodiment, the carrier assembly 1 is movably mounted within the housing 5. The carrier assembly 1 can be moved by the gravity of the drone 101, allowing at least a portion of the fluid in the third fluid chamber to flow into the fourth fluid chamber. In this embodiment, the gravity of the drone 101 is utilized to drive at least a portion of the fluid in the third fluid chamber to flow into the fourth fluid chamber. When the volume of the third fluid chamber decreases, the movable section 912 retracts or folds relative to the fixed section 911, thereby driving the cover 8 to close the opening. This eliminates the need for external energy to drive the cover 8 to close the opening, conserving energy and reducing the risk of circuit failure.

[0148] In one embodiment, reference Figure 4The retractable device 100 further includes a first fixing member 10 and a second fixing member 11. The first fixing member 10 is fixedly connected to the housing 5, and the second fixing member 11 is fixedly connected to the carrier assembly 1. The fourth fluid-containing component 93 is fixedly connected to the first fixing member 10 and the second fixing member 11, respectively. The carrier assembly 1 can be moved by the gravity of the drone 101, thereby driving the second fixing member 11 to move away from the first fixing member 10. Because the fourth fluid-containing component 93 is fixedly connected to the first fixing member 10 and the second fixing member 11, respectively, movement of the second fixing member 11 away from the first fixing member 10 causes the fourth fluid-containing component 93 to expand. When the fourth fluid-containing component 93 expands, negative pressure is generated within the fourth fluid-containing component 93. Under the action of the negative pressure, at least part of the fluid in the third fluid-containing component 92 flows into the fourth fluid-containing component 93, causing the volume of the third fluid chamber of the third fluid-containing component 92 to decrease. The contraction of the third fluid-containing component 92 causes the movable section 912 and the cover 8 to retract or fold relative to the fixed section 911, thereby closing the opening of the cover 8. The drone 101 is placed on the object-carrying assembly 1 , and the cover 8 can automatically close the opening as the object-carrying assembly 1 moves, eliminating the need for manual operation and simplifying the operation steps of closing the cover 8 .

[0149] In one embodiment, reference Figure 3 and Figure 4 The third fluid-containing component 92 is at least partially located within the telescopic rod assembly 91. When the cover 8 is moved to open, the cover 8 drives the movable section 912 to move away from the housing 5 relative to the fixed section 911, thereby reducing the volume of the fourth fluid chamber. The third fluid-containing component 92 is at least partially located within the telescopic rod assembly 91, which reduces the space occupied by the third fluid-containing component 92 when the cover 8 is open. Furthermore, the telescopic rod assembly 91 protects the third fluid-containing component 92.

[0150] In one embodiment, reference Figure 4 The retractable device 100 further includes a third elastic member 12 connected to the fourth fluid-containing member 93. The third elastic member 12 is configured to drive the fourth fluid-containing member 93 to deform, thereby reducing the volume of the fourth fluid chamber. The third elastic member 12 can provide a driving force for the deformation of the fourth fluid-containing member 93, thereby accelerating the reduction of the fourth fluid chamber's volume.

[0151] In a specific embodiment, the fourth fluid holding member 93 has a first connecting portion and a second connecting portion. The first connecting portion is fixedly connected to the first fixing member 10, and the second connecting portion is fixedly connected to the second fixing member 11. One end of the third elastic member 12 is fixedly connected to the first connecting portion, and the other end is fixedly connected to the second connecting portion. When the second fixing member 11 moves away from the first fixing member 10, it pulls the third elastic member 12, causing the third elastic member 12 to deform. The third fluid holding member 92 is fixedly connected to the movable section 912. When the cover 8 is opened, the cover 8 can drive the movable section 912 to move away from the fixed section 911. The movable movement causes the third fluid holding member 92 to expand. After the third fluid holding member 92 expands, negative pressure is generated inside. Under the action of the negative pressure, at least part of the fluid in the fourth fluid holding member 93 flows into the third fluid holding member 92, causing the fourth fluid holding member 93 to shrink in volume. At the same time, the third elastic member 12 recovers its elastic deformation and drives the second fixing member 11 to move closer to the first fixing member 10. The second fixing member 11 is deformed. When the component 11 moves, it can drive the carrier assembly 1 to move. When the carrier assembly 1 moves, it can drive the extrusion component 7 to move, driving the volume of the first fluid chamber to decrease. The driving force applied by the first air pipe to the first movable component and the second movable component is reduced, thereby reducing the tension applied by the first movable component to the first clamping component 21 and the tension applied by the second movable component to the second clamping component 22. Under the action of the reset component, the first clamping component 21 can move in a direction away from the drone 101, and the second clamping component 22 can move in a direction away from the drone 101 under the action of the reset component to release the drone 101. In other words, when the cover 8 is opened, it can drive the first clamping component 21 and the second clamping component 22 to move to release the drone 101.

[0152] In one embodiment, a rotating shaft 51 is provided on the housing 5 , one end of the cover 8 is rotatably connected to the rotating shaft 51 , and the other end is fixedly connected to the movable section 912 .

[0153] In one embodiment, a transparent window 52 is provided on the shell 5. When it is necessary to manually rotate the driving member 32 to drive the extruding member 7 to move to adjust the positions of the first clamping member 21 and the second clamping member 22, the user can observe the positions of the first clamping member 21 and the second clamping member 22 through the transparent window 52, so as to judge whether the first clamping member 21 and the second clamping member 22 can just clamp and fix the drone 101.

[0154] The above is a detailed introduction to the embodiments of the present application. Specific examples are used herein to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method and core idea of the present application. At the same time, for those skilled in the art, based on the ideas of the present application, there may be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
