Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of unmanned aerial vehicles, in particular to a mobile apron and a vehicle. Background Art
[0002] In the context of the rapid development of modern drone technology, large drones, as key tools in fields such as emergency rescue, environmental monitoring, and logistics distribution, their efficient and flexible deployment capabilities are particularly important. Currently, most large drone mobile aprons on the market adopt a combination of a tractor and a semi-trailer, with the apron set on the frame of the semi-trailer. Although this design improves the mobile deployment ability of the drone to a certain extent and allows for rapid takeoff and landing in relatively wide areas, its inherent limitations are gradually emerging: due to the large volume of such apron systems (even when the apron system is in a folded state, the occupied area still requires the entire frame of the semi-trailer), when operating in complex urban environments, limited by the large turning radius, it is difficult to move freely between narrow streets and alleys. Coupled with insufficient climbing performance, it severely restricts its applicable range in diverse terrains.
[0003] Especially when dealing with emergencies such as forest fires, the rescue paths are often winding, the mountain roads are rough and the slope changes greatly. The above-mentioned defects of the existing mobile apron are particularly prominent, which not only affects the ability of the drone to quickly reach the fire site, but may also delay the best fire extinguishing opportunity due to various obstacles on the way, thus exacerbating the disaster losses. Summary of the Utility Model
[0004] In order to overcome the deficiencies of the prior art, the purpose of the utility model is to provide a mobile apron and a vehicle to solve the problem that the current mobile apron occupies a large area in the folded state.
[0005] The purpose of the utility model is achieved by adopting the following technical solutions:

[0007] The apron includes a base plate and a sub-plate, and the sub-plate is movably connected to the base plate; the apron has a deployed state and a stored state, and the plane where the base plate is located is denoted as the reference plane. When the apron is in the deployed state, the area on the reference plane is larger than the area on the reference plane when the apron is in the stored state;
[0008] Both ends of the lifting mechanism are respectively connected to the base and the base plate, and the lifting mechanism is used to adjust the distance between the base plate and the base.
[0009] In some alternative embodiments, the sub-board includes a first folding board, which is rotatably connected to the side of the base board. When the apron is in the unfolded state, the first folding board is coplanar with the base board.

[0013] In some alternative embodiments, the sub-board includes a third folding board, which is rotatably connected to the end of the base board. When the apron is in the unfolded state, the third folding board is coplanar with the base board. When the apron is in the stored state, the third folding board is perpendicular to the first folding board.
[0014] In some alternative embodiments, the sub-board includes a fourth folding board, which is rotatably connected to the side of the third folding board. When the apron is in the unfolded state, the fourth folding board is coplanar with the base board. When the apron is in the stored state, the fourth folding board is perpendicular to the third folding board.
[0015] In some alternative embodiments, a first support assembly is further included. The first support assembly includes a first support arm, one end of the first support arm is movably connected to the base, and the other end of the first support arm abuts against the first folding board when the apron is in the unfolded state.
[0016] In some alternative embodiments, a second support assembly is further included. The second support assembly includes a second support arm, one end of the second support arm is movably connected to the base, and the other end of the second support arm abuts against the third folding board and / or the fourth folding board when the apron is in the unfolded state.
[0017] In some alternative embodiments, a sliding table is slidably provided on the base, and the sliding direction of the sliding table is parallel to the extending direction of both ends of the base board;
[0018] The number of the second support assemblies is multiple. At least one of the second support assemblies is located on the base, and one end of the second support arm of at least one of the second support assemblies is movably connected to the sliding table.
[0019] In some alternative embodiments, an actuating device is further included. The actuating device is respectively connected to the substrate and the daughter board, and the actuating device provides power to drive the relative movement of the substrate and the daughter board;

[0021] To solve the same technical problem, the present utility model further provides a vehicle including the mobile apron as described above.
[0022] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0023] The daughter board and the substrate of the apron are movably connected. When the apron is in the deployed state, the daughter board and the substrate can be used for aircraft takeoff and landing, and the lifting mechanism can lift the substrate from the base to prevent the apron in the deployed state from interfering with other structures of the vehicle carrier such as the cab. When the apron is in the stowed state, the lifting mechanism lowers the substrate and makes it close to the base to achieve the rapid transfer of the apron. Based on the above structure, the setting of the apron does not need to consider the interference avoidance design with other structures on the vehicle carrier. In particular, the area required by the apron in the stowed state is smaller, and it can adapt to vehicle carriers with smaller sizes. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Embodiment 1
[0035] Combined with Figure 1 and Figure 5 As shown, the mobile apron of the present utility model is schematically shown, including an apron 10, a base 20 and a lifting mechanism 30. Among them, the base 20 is the basic structure of the apron 10 and the lifting mechanism 30, and the base 20 can be placed on various vehicles, concrete bases, or even temporarily placed in a container.
[0036] The apron 10 includes a base plate 11 and a sub - plate 12. The sub - plate 12 is movably connected to the base plate 11. The connection between the base plate 11 and the sub - plate 12 can be a rotational connection (shaft hinge, ball hinge) or a sliding connection (slider - guide connection). The apron 10 has a deployed state and a stored state. The plane where the base plate 11 is located is denoted as the reference plane. When the apron 10 is in the deployed state, the area on the reference plane is larger than that when the apron 10 is in the stored state. When the apron 10 is in the deployed state, the occupied area of the apron 10 is larger. At this time, the basic plane formed by the base plate 11 and the sub - plate 12 can be used for the take - off and landing of aircraft. When the apron 10 is in the stored state, the occupied area of the apron 10 is smaller, so as to be carried by a vehicle or container that can carry this mobile apron for transfer.
[0037] Both ends of the lifting mechanism 30 are respectively connected to the base 20 and the base plate 11. The lifting mechanism 30 is used to adjust the distance between the base plate 11 and the base 20. For example, when the base 20 is set on an existing vehicle, the lifting mechanism 30 can lift or lower the base plate 11. When the apron 10 is in the stored state, the lifting mechanism 30 lowers the base plate 11 (reducing the distance between the base plate 11 and the base 20). When the apron 10 is in the deployed state, the lifting mechanism 30 raises the base plate 11 (increasing the distance between the base plate 11 and the base 20). This makes the base plate 11 slightly higher than the cab of the vehicle. After the apron 10 is completely switched to the deployed state, the sub - plate 12 can be arranged above the cab of the vehicle to make full use of the space above the vehicle. In this way, a smaller vehicle can be used to transport this mobile apron, improving the transportation convenience and applicability of this mobile apron, so that it can be transferred and used in more environments.
[0038] Embodiment 2
[0039] The difference between this embodiment and Embodiment 1 is that the number of sub - plates 12 is set to be multiple. The multiple sub - plates 12 are connected end to end, and two adjacent sub - plates 12 are rotationally connected. The sub - plate 12 at the head or the tail is rotationally connected to the base. When the apron 10 is in the deployed state, the base plate 11 and the multiple sub - plates 12 are coplanar for the take - off and landing of aircraft. When the apron 10 is in the stored state, the multiple sub - plates 12 are wound around a rotating shaft to form a curtain structure to reduce the occupied area of the apron 10.
[0040] Embodiment 3
[0041] Combined with Figures 1 to 6As shown, the difference between this embodiment and Embodiment 1 is that the daughter board 12 includes a first folding board 121 and a second folding board 122. The first folding board 121 is rotatably connected to the side of the base board 11. When the apron 10 is in the unfolded state, the first folding board 121 is coplanar with the base board 11. When the apron 10 is in the stored state, the first folding board 121 is inclined, perpendicular or parallel to the base board 11, preferably perpendicular. The base board 11 and the second folding board 122 are respectively rotatably connected to both sides of the first folding board 121. When the apron 10 is in the unfolded state, the second folding board 122 is coplanar with the base board 11. When the apron 10 is in the stored state, the first folding board 121 is perpendicular to the base board 11, and the second folding board 122 is parallel to the base board 11. That is, when the apron 10 is in the stored state, the second folding board 122, the first folding board 121 and the base board 11 form a C-shaped structure.
[0042] Specifically, as Figure 3 and Figure 4 , two first folding boards 121 and two second folding boards 122 are provided. The two first folding boards 121 are respectively located on both sides of the base board 11. When the apron 10 is in the stored state, the sides of the two second folding boards 122 are in contact with each other. The cross-section of the base board 11, the two first folding boards 121 and the two second folding boards 122 is in a shape of a loop. In other words, the base board 11, the two first folding boards 121 and the two second folding boards 122 form a hollow enclosed structure when the apron 10 is in the stored state. Accessories required for aviation or even the folded aircraft can be placed inside this enclosed structure. In order to stably maintain the apron 10 in the stored state, a lock can be adaptively provided on the side of the second folding board 122. When the sides of the two second folding boards 122 are in contact with each other, the sides of the two second folding boards 122 can be buckled with each other through the above-mentioned lock.
[0043] In order to further expand the occupied area of the apron 10 in the unfolded state, as Figures 1 to 3 , the daughter board 12 includes a third folding board 123 and a fourth folding board 124. The third folding board 123 is rotatably connected to the end of the base board 11. When the apron 10 is in the unfolded state, the third folding board 123 is coplanar with the base board 11. When the apron 10 is in the stored state, the third folding board 123 is perpendicular to the first folding board 121. The fourth folding board 124 is rotatably connected to the side of the third folding board 123. When the apron 10 is in the unfolded state, the fourth folding board 124 is coplanar with the base board 11. When the apron 10 is in the stored state, the fourth folding board 124 is perpendicular to the third folding board 123, and at the same time, the fourth folding board 124 is perpendicular to the base board 11.
[0044] In this embodiment, as Figure 2, there are two third folding plates 123, and the two third folding plates 123 are respectively located at both ends of the base plate 11. There are four fourth folding plates 124, and two of the fourth folding plates 124 are respectively arranged on both sides of one of the third folding plates 123, and the other two fourth folding plates 124 are respectively arranged on both sides of the other third folding plate 123. When the apron 10 is switched from the storage state to the unfolded state, first unfold the fourth folding plate 124 so that the fourth folding plate 124 is coplanar with the third folding plate 123, and then unfold the third folding plate 123 so that it is coplanar with the base plate 11, and finally the base plate 11, the third folding plate 123 and the fourth folding plate 124 are coplanar.
[0045] Of course, the unfolding or folding sequence of the first folding plate 121, the second folding plate 122, the third folding plate 123 and the fourth folding plate 124 can be adaptively adjusted according to the actual situation. The above unfolding or folding sequence is only for illustrative purposes and does not limit the unfolding or folding sequence. The mobile apron also includes an actuator. The actuator is respectively connected to the base plate 11 and the sub-plate 12 (i.e., the above-mentioned folding plates). The actuator provides power to drive the relative movement of the base plate 11 and the sub-plate 12. The unfolding or folding actions of the above-mentioned folding plates can be driven by existing actuators such as motors, electric cylinders, air cylinders or hydraulic cylinders. In order to avoid damage to the apron 10 caused by incorrect unfolding or folding sequences of the folding plates, the mobile apron also includes a visual recognition device 90 and a safety control device. The visual recognition device 90 is used to photograph and identify the movement states of the base plate 11 and the sub-plate 12. The actuator slows down or cuts off the power when the above movement states are abnormal. The safety control device is used to slow down or cut off the power of the actuator when the above movement states are abnormal. In this embodiment, the actuator is preferably a hydraulic cylinder, and the safety control device is preferably a pressure relief valve. When the unfolding or folding sequences of the folding plates are incorrect, the resistance received by the actuator increases sharply, and the hydraulic pressure inside it increases and exceeds the pressure relief value of the safety control device. At this time, the safety control device starts to relieve pressure to weaken the power of the actuator and protect the base plate 11 and the sub-plate 12. Combined Figure 2 and Figure 3As shown, in order to support the first folding plate 121 and the second folding plate 122, the mobile apron further includes a first support assembly. The first support assembly includes a first support arm 40. One end of the first support arm 40 is movably connected to the base 20. The other end of the first support arm 40 abuts against the first folding plate 121 and the second folding plate 122 when the apron 10 is in the unfolded state. The first support arm 40 is preferably a scissor-type support arm. When the first support arm 40 is folded, it disengages from the first folding plate 121 and the second folding plate 122. When the first support arm 40 extends, it abuts against the first folding plate 121 and the second folding plate 122. In this embodiment, each first folding plate 121 (or the second folding plate 122) is equipped with two corresponding first support arms 40 in advance. These two first support arms 40 can abut against both sides of one surface of the first folding plate 121 and the second folding plate 122, so that the apron 10 can carry heavier aircraft.
[0046] As Figure 5 and Figure 6 , and in order to support the third folding plate 123 and the fourth folding plate 124, the mobile apron further includes a second support assembly. The second support assembly includes a second support arm 50. One end of the second support arm 50 is movably connected to the base 20. The other end of the second support arm 50 abuts against the third folding plate 123 and / or the fourth folding plate 124 when the apron 10 is in the unfolded state. The second support arm 50 is preferably a scissor-type support arm. When the second support arm 50 is folded, it disengages from the third folding plate 123 and the fourth folding plate 124. When the second support arm 50 extends, it abuts against the third folding plate 123 and the fourth folding plate, so that the apron 10 can carry heavier aircraft.
[0047] Further, a sliding table 60 is slidably provided on the base 20, as Figure 1 and Figure 4 , the sliding direction of the sliding table 60 is parallel to the extension direction of both ends of the substrate 11. The number of the second support assemblies is multiple. At least one second support assembly is located on the base 20. One end of the second support arm 50 of at least one second support assembly is movably connected to the sliding table 60. The sliding table 60 can drive the second support assembly provided thereon to slide relative to the base 20 to expand the support range of the second support arm 50 of the second support assembly. A sliding arm 70 is slidably provided on the base 20. A support leg 80 is provided at the end of the sliding arm 70. The support leg 80 can be telescoped and supported on the ground to reduce the downward pressure of the apron 10 and the aircraft on the vehicle. The above-mentioned first support assembly or second support assembly can be provided on the sliding arm 70. Similar to the principle of the sliding table 60, the setting of the sliding arm 70 can increase the support range of the first support assembly or the second support assembly for the apron 10.
[0048] In addition, the lifting mechanism 30 is preferably a scissor-type elevator.
[0049] Embodiment 4
[0050] The difference between this embodiment and Embodiment 3 is that the first support arm 40 and the second support arm 50 can be hydraulic cylinder arms, and the hydraulic cylinder arms can also achieve extension and contraction. When the hydraulic cylinder arms extend, they can abut against one side of the corresponding folding plate.
[0051] Embodiment 5
[0052] To solve the same technical problem, this embodiment also provides a vehicle, including the mobile apron described above. The vehicle can be a land vehicle or a water vehicle. The land vehicle can be a wheeled vehicle. The base 20 of the mobile apron is installed on the chassis of the wheeled vehicle. When the apron 10 is in the deployed state, the lifting mechanism 30 lifts the base plate 11 so that some of the sub - plates 12 after deployment overlap on the top of the cab of the wheeled vehicle. A bearing arm can be provided on the top of the cab, and the bearing arm and the top of the cab can be slidably connected or rotatably connected. The bearing arm is used to support some of the sub - plates 12 overlapping on the top of the cab.
[0053] In summary, the sub - plate 12 and the base plate 11 of the apron 10 are movably connected. When the apron 10 is in the deployed state, the sub - plate 12 and the base plate 11 can be used for aircraft take - off and landing, and the lifting mechanism 30 can lift the base plate 11 from the base 20 to prevent the apron 10 in the deployed state from interfering with other structures of the vehicle carrier such as the cab. When the apron 10 is in the stowed state, the lifting mechanism 30 lowers the base plate 11 and makes it close to the base 20 to achieve the rapid transfer of the apron 10. Based on the above structure, the setting of the apron 10 does not need to consider the interference avoidance design with other structures on the vehicle carrier. In particular, the area required by the apron 10 in the stowed state is smaller, and it can adapt to smaller - sized vehicle carriers.
[0054] The above are only the embodiments of the present invention, and thus do not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present invention.
