[0035] Embodiments of the present invention are described in detail below, and the embodiments described with reference to the accompanying drawings are exemplary.
[0036] like Figures 1 to 5 As shown, a lifting platform of an embodiment of the first aspect of the utility model includes a load-bearing device 10 and a first lifting adjustment device 3, wherein the load-bearing device 10 is suitable for placing a load 7; one end of the first lifting adjustment device 3 has at least two connection points with the load-bearing device 10, and the other end of the first lifting adjustment device 3 is suitable for fixing the load-bearing device 10; wherein the maximum distance difference between at least two connection points and the reference plane is less than a preset distance value.
[0037] Embodiments of the present invention are described in detail below, and the embodiments described with reference to the accompanying drawings are exemplary.
[0038] like Figures 1 to 5 As shown, a lifting platform of an embodiment of the first aspect of the utility model includes a load-bearing device 10 and a first lifting adjustment device 3, wherein the load-bearing device 10 is suitable for placing a load 7; one end of the first lifting adjustment device 3 has at least two connection points with the load-bearing device 10, and the other end of the first lifting adjustment device 3 is suitable for fixing the load-bearing device 10; wherein the maximum distance difference between at least two connection points and the reference plane is less than a preset distance value.
[0039] Specifically, the load-bearing device 10 is placed on the first lifting and adjusting device 3, and the load 7 is placed on the load-bearing device 10. One end of the first lifting and adjusting device 3 has at least two connection points with the load-bearing device 10, and the two connections have a certain distance. The two connection points can perform lifting and lowering movements independently, and the lifting height can be adjusted automatically. The other end of the first lifting and adjusting device 3 is used to fix the lifting platform. The base of the first lifting and adjusting device 3 itself can be used as a fixed structure, and a special fixed base 2 can also be set. The fixed base 2 can be placed on any reference plane. The first lifting and adjusting device 3 can adjust the horizontal angle or distance between the load-bearing device 10 and any reference plane where the fixed base 2 is placed. By adjusting the distance between at least two connection points of the first lifting and adjusting device 3 and the fixed base 2, the horizontal angle or distance between the load-bearing device 10 and any reference plane where the fixed base 2 is placed can be controlled, so that the load-bearing device 10 and any reference plane are always in a parallel position, preventing the state of the load-bearing device 10 and the reference plane from changing due to the tilt or shaking of the plane.
[0040] At the same time, the first lifting and adjusting device 3 can also support the carrying device 10 and adjust the height of the carrying device 10 to control the carrying device 10 to be in the best working position.
[0041] The first lifting adjustment device 3 and the carrying device 10 have at least two connection points. The maximum distance difference between at least two connection points of the carrying device 3 and the reference plane is adjusted by the first lifting adjustment device 3 to be less than a preset distance value, thereby achieving smooth and safe take-off and landing of the drone parked on the lifting platform under bumpy road conditions, and avoiding the risk of collision of the drone due to tilting when it stays on the lifting platform.
[0042] According to some embodiments, the reference plane is a horizontal plane, which can keep the carrying device 10 always in a horizontal position, and prevent the carrying device 10 from tilting due to bumps during movement, thereby protecting the drone's smooth takeoff and landing and safe stop.
[0043] According to some embodiments, the first lifting and adjusting device 3 is a retractable member, and each point where the first lifting and adjusting device 3 contacts the load-bearing device 10 has a retractable function, and each connection point can be adjusted separately. When the load-bearing device 10 is tilted, the distance between each connection point can be adjusted by the retractable member. For example: on the high side of the load-bearing device 10, the retractable length of the retractable member can be controlled to be lower, and on the low side of the load-bearing device 10, the retractable length of the retractable member can be controlled to be higher, so that the horizontal state of the load-bearing device 10 can be adjusted accordingly by adjusting the height of the retractable member.
[0044] According to some embodiments, Figure 1 and 2As shown, there can be multiple first lifting adjustment devices 3, and multiple first lifting adjustment devices 3 are evenly arranged on the lower surface of the load-bearing device 10. Multiple first lifting adjustment devices 3 can be evenly arranged along the circumference or radial direction of the lower surface of the load-bearing device 10. At this time, each first lifting adjustment device 3 is a separate telescopic component, and the load-bearing device 10 is always in a horizontal position by telescopic adjustment based on the same principle. At the same time, the first lifting adjustment device 3 can be a single component, for example: having a main rod, and a separately adjustable telescopic rod connected between the main rod and a point.
[0045] Optionally, the number of the first lifting and adjusting devices 3 can be appropriately adjusted according to the size and weight of the load-bearing device 10 and the load 7. In one embodiment, three first lifting and adjusting devices 3 are provided, which can provide sufficient support for the load-bearing device 10 and the load 7 and ensure their stability.
[0046] According to some embodiments, Figure 3 As shown, the first lifting and adjusting device 3 includes a threaded sleeve 309, a first screw rod 301 and a first motor 305, the first motor 305 is connected to the first screw rod 301, the first screw rod 301 is rotatably connected to the threaded sleeve 309, and the threaded sleeve 309 is movably connected to the carrying device 10.
[0047] Specifically, the first motor 305 provides power for the first lifting and adjusting device 3, and drives the first screw rod 301 to rotate. The threaded sleeve 309 is provided with threads, and the surface of the first screw rod 301 is provided with threads. The first screw rod 301 and the threaded sleeve 309 are rotatably connected through the threads. When the first motor 305 drives the first screw rod 301 to rotate, the threaded sleeve 309 can be driven to move up and down, thereby driving the carrying device 10 to move.
[0048] According to some embodiments, the first lifting adjustment device 3 includes a spring coupling 307 and a second screw rod 308, one end of the second screw rod 308 is connected to the threaded sleeve 309, the other end of the second screw rod 308 is connected to the spring coupling 307, and the spring coupling 307 is movably connected to the carrying device 10. The spring coupling 307 has a telescopic function, and can support and adjust the height and telescopic distance of the carrying device 10.
[0049] Specifically, the second screw rod 308 moves up and down with the threaded sleeve 309, and drives the spring coupling 307 to do lifting movement. The dynamic spring coupling 307 is composed of a half coupling, a spring assembly and an intermediate sleeve; the two half couplings are respectively connected to the driving shaft and the driven shaft, and the spring assembly plays the role of transmitting torque and buffering vibration. When the driving shaft rotates, the torque is transmitted to the driven shaft through the elastic deformation of the spring assembly, thereby realizing the synchronous rotation between the two shafts. During normal operation, when the driving shaft is subjected to the driving torque, the spring assembly will undergo elastic deformation and transmit the torque to the driven shaft. Since the spring assembly has a certain elasticity, it can absorb and buffer the vibration and impact during the transmission process to a certain extent. Therefore, the spring coupling also has good coaxiality adaptability and can work normally when there is a certain deviation between the two shafts. Therefore, the shaking of the load-bearing device 10 can be adjusted, absorbed and buffered during the bumping and shaking of the lifting platform, so that the load-bearing device 10 always maintains a horizontal position.
[0050] According to some embodiments, the first lifting adjustment device 3 includes a first gear 306 and a second gear 302 , the first motor 305 is connected to the first gear 306 , the first gear 306 and the second gear 302 are meshed, and the second gear 302 is fixed on the first screw rod 301 .
[0051] Specifically, the second lifting and adjusting device 3 also includes a connecting shaft 304 and a bearing seat 303. The connecting shaft 304 is connected to the first motor 305. The first gear 306 is fixed on the connecting shaft 304. The lower end of the first screw rod 301 is rotatable in the shaft hole of the connecting bearing seat 303. The bearing seat 303 is fixed to other fixed structures for fixing the first lifting and adjusting device 3.
[0052] When the first motor 305 is started, it drives the connecting shaft 304 and the first gear 306 to rotate, the first gear 306 and the second gear 302 mesh and rotate, and drives the first screw rod 301 to rotate. Since the bearing seat 303 is fixed, the first screw rod 301 follows the second gear 302 to rotate relative to the bearing seat 303 in the up and down direction, which can drive the threaded sleeve 309 and the second screw rod 308 to move, and control the movement of the spring coupling 307 to move up and down with other components, so as to achieve the purpose of adjusting the height and horizontal state of the load-bearing device 10. Optionally, the spring coupling 307 here preferably selects a serpentine spring coupling, and other spring couplings can also be selected. The serpentine spring coupling can withstand the torque generated when each axis performs different lifting movements, and the effect will be better.
[0053] Optionally, the first motor 305 is preferably a servo motor, which can be used to accurately control the rotation angle and shaft lifting distance of the first lifting adjustment device 3, so that the adjustment response speed of the first lifting adjustment device 3 is faster and the regulation is more precise.
[0054] According to some embodiments, the lifting platform further includes a control system 8 , which is electrically connected to the first motor 305 , and the control system 8 is suitable for controlling the start and stop of the first motor 305 , and adjusting the first lifting adjustment device 3 .
[0055] Specifically, the first motor 305 is electrically connected to the microcontroller 8, and the microcontroller 8 controls the start and stop of the first motor 305. The control system 8 has a built-in computing module and a control module, and the computing module can calculate the specific distance that each first lifting adjustment device 3 needs to adjust through the external environment data collected by the control system 8, and quickly control the start and running time of the first motor 305, thereby controlling the adjustment distance or height of each first lifting adjustment device 3, and adjusting the lifting and horizontal state of the carrying device 10.
[0056] According to some embodiments, the control system 8 also includes a detection device 81, which is electrically connected to the carrying device 10. The detection device 81 is used to detect the horizontal state of the carrying device 10, and adjust the first lifting and adjusting device 3 through the control system 8 based on the detected horizontal state, thereby adjusting the lifting height and horizontal state of the carrying device 10.
[0057] Specifically, the detection device 81 detects and obtains data such as the angle between the carrying device 10 and the horizontal plane, acceleration, gravitational acceleration, etc., and quickly transmits the detected data to the operation module of the control system 8. The operation module calculates the data obtained by the detection device 81, and quickly controls the first lifting and adjusting device 3 to adjust the specific distance through the control module. The multiple first lifting and adjusting devices 3 each lift different heights or distances, so that the carrying device 10 is always in a horizontal position.
[0058] According to some embodiments, Figure 5 As shown, the detection device 81 includes at least one of a gravity sensor, an angle sensor, an acceleration sensor and a gyroscope. The gravity sensor is used to detect the gravity of the load-bearing device 10, the angle sensor is used to detect the angle between the load-bearing device 10 and the horizontal plane, and the acceleration sensor and the gyroscope are used to detect the acceleration of the load-bearing device 10 in the horizontal plane direction or other directions; the gravity sensor, the angle sensor, the acceleration sensor and the gyroscope quickly transmit the data detected by each to the calculation module of the control system 8, so that the control system 8 can calculate and adjust the horizontal state of the load-bearing device 10 more accurately and precisely.
[0059] According to some embodiments, Figure 2 As shown, the carrying device 1 includes an outer carrying platform 1 and an inner carrying platform 5 , and the outer carrying platform 1 and the inner carrying platform 5 are located in the same or different planes along the first direction.
[0060] Specifically, the inner load-bearing platform 5 is used to carry the load 7, and the outer load-bearing platform 1 and the inner load-bearing platform 5 form a storage space that can accommodate the load 7, so that the load 7 is accommodated in the load-bearing device 10. Such a structural design can save space and protect the load 7 at the same time. The outer load-bearing platform 1 has a through hole inside, and the inner load-bearing platform 5 can be combined with the through hole inside the outer load-bearing platform 1. At this time, multiple first lifting and adjusting devices 3 are connected to the outer load-bearing platform 1, and the multiple first lifting and adjusting devices 3 can be evenly arranged along the circumference or radial direction of the lower surface of the outer load-bearing platform 1, for supporting and adjusting the outer load-bearing platform 1 and / or the inner load-bearing platform 5.
[0061] Optionally, the outer bearing platform 1 and the inner bearing platform 5 can be of any shape, but the shape of the inner bearing platform 5 must be consistent with the shape of the through hole inside the outer bearing platform 1, and can be perfectly combined with each other.
[0062] Optionally, the outer bearing platform 1 can be set to be annular with a circular through hole in the middle; the inner bearing platform 5 is also circular, and the radius of the inner bearing platform 5 is slightly smaller than or equal to the radius of the circular through hole in the middle of the outer bearing platform 1, and the two can be combined and separated from each other. When the outer bearing platform 1 and the inner bearing platform 5 are combined, the outer bearing platform 1 and the inner bearing platform 5 are located in the same plane along the first direction, for example, if the first direction is a horizontal plane, the heights of the outer bearing platform 1 and the inner bearing platform 5 along the horizontal plane are consistent, and they are rigidly combined with each other; when the outer bearing platform 1 and the inner bearing platform 5 are separated, the outer bearing platform 1 and the inner bearing platform 5 are located in different planes along the first direction, for example, if the first direction is a horizontal plane, the heights of the outer bearing platform 1 and the inner bearing platform 5 along the horizontal plane are different.
[0063] Optional, such as Figure 2 As shown, when the lifting platform is in a non-working state, there is a height difference between the inner load-bearing platform 5 and the outer load-bearing platform 1, the inner load-bearing platform 5 is lower than the outer load-bearing platform 1, and the inner load-bearing platform 5 and the outer load-bearing platform 1 form a storage space capable of accommodating the load 7. In the working state, the inner load-bearing platform 5 is combined with the outer load-bearing platform 1 and is in the same horizontal plane, so that the load 7 is arranged on the inner load-bearing platform 5 and the outer load-bearing platform 1, which can provide sufficient working space and support for the load 7, so that the load 7 is easy to move or fly.
[0064] According to some embodiments, Figure 5 As shown, the inner carrying platform 5 is electrically connected to the detection device 81. The control system 8 is adapted to control the first lifting device 3 to adjust the lifting and / or horizontal state of the outer carrying platform 1 and / or the inner carrying platform 5 according to the detection result of the detection device 81.
[0065] Specifically, the detection device 81 is set at the edge, center or specific position of the inner bearing platform 5.

When the second lifting and adjusting device 4 and the inner bearing platform 5 are in a retracted state or in the process of the second lifting and adjusting device 4 supporting the lifting of the inner bearing platform 5, the fourth stopper 408 and the third stopper 504 are combined with each other to prevent the second lifting and adjusting device 4 and the inner bearing platform 5 from being misaligned and separated from each other due to bumps and shaking during the lifting process; when the second lifting and adjusting device 4 supports the lifting of the inner bearing platform 5 to a preset height, the fourth stopper 408 and the third stopper 504 are separated.
[0081] Among them, the preset height is generally the height at which the inner load-bearing platform 5 and the outer load-bearing platform 1 need to be combined. In the process of the lifting platform rising, the preset height is the height at which the inner load-bearing platform 5 rises to the same level as the outer load-bearing platform 1.

In the process of the lifting platform falling back, the preset height is the height at which the inner load-bearing platform 5 and the outer load-bearing platform 1 fall together to the initial height of the outer load-bearing platform 1. At this time, the inner load-bearing platform 5 is separated from the outer load-bearing platform 1, the second lifting and adjusting device 4 and the inner load-bearing platform 5 are combined, and they fall together to the initial position, and the first lifting device 3 and the outer load-bearing platform 1 are no longer falling.

[0083] Optionally, multiple fourth limit members 408 and third limit members 504 can be set, and the number can be determined according to the size, weight, function, etc. of the inner load-bearing platform 5 and the load 7. The positions of the fourth limit members 408 and the third limit members 504 can also be evenly arranged around the protrusion of the fixed platform 401 and the groove of the inner load-bearing platform 5 according to the number.
[0084] Optionally, the fourth limiting member 408 and the third limiting member 504 may also be other rigid interlocking devices.

[0086] Specifically, the lifting platform also includes a fixed base 2, which is used to fix the entire lifting platform. The fixed base 2 can be set up by itself and has sufficient functions to fix the lifting platform. For example, if the lifting platform is mounted on a vehicle, the fixed base 2 is a fixed structure of the vehicle body. The fixed base 2 is fixedly connected to the base 404, and can fix the second lifting device 4. At the same time, the fixed base 2 can also be fixedly connected to the bearing seat 303, and is used to fix the first lifting device 3.
[0087] Optionally, the second lifting adjustment device 4 further includes a support platform 402, a fork arm structure 403, a second motor 406, and a screw rod 407; wherein the base 404 is fixedly mounted on the fixed platform 2, the control system 8 is mounted in a groove formed by the fixed platform 2 and the base 404, the microcontroller 8 is electrically connected to the motor 406, the motor 406 is connected to the screw rod 407, the screw rod 407 is connected to the fork arm structure 403, the fork arm structure 403 is rotatably connected to the base 404 and the support platform 402, and the support platform 402 is placed on the fork arm structure 403, and the fixed platform 401 is fixedly placed on the support platform 402. The control system 8 controls the second motor 406 to drive the screw rod 407 to rotate, the screw rod 407 stretches or contracts, drives the fork arm structure 403 to rotate in the height direction, drives the support platform 402 to do lifting motion, and thus drives the fixed platform 401 to do lifting motion.
[0088] According to some embodiments, the carrier 7 includes a drone, and the lifting platform is suitable for carrying the take-off and landing of the drone.
[0089] Specifically, when the load 7 is a drone, the lifting platform can be used for the take-off and landing of the drone. When the drone needs to take off or land, the lifting platform is in the working position, at which time the inner load-bearing platform 5 and the outer load-bearing platform 1 are in the same horizontal position, and are combined with each other to support the drone together, ensuring the safety and successful take-off and landing of the drone. When the inner load-bearing platform 5 and the outer load-bearing platform 1 are in a bumpy, shaking, or tilted state, by adjusting the horizontal state of the inner load-bearing platform 5 and the outer load-bearing platform 1, the drone is always in a horizontal position and a safe state during the take-off or landing process, preventing the risk of the drone being damaged by the tilting of the drone during the take-off or landing process or the collision with the drone. At the same time, when the drone is not working, the inner load-bearing platform 5 and the outer load-bearing platform 1 are at different horizontal heights, and the accommodation space formed by the inner load-bearing platform 5 and the outer load-bearing platform 1 can be used as a drone warehouse for parking the drone, which can not only protect the drone, but also save the space occupied by the drone when it is in the parking position.
[0090] A vehicle-mounted UAV lifting platform according to an embodiment of the second aspect of the present application includes the above-mentioned lifting platform.
[0091] Specifically, when the drone lifting platform is in a non-working state, the drone lifting platform is in an initial position as a whole. At this time, the drone is parked on the inner carrying platform 5, the first lifting adjustment device 3 and the second lifting adjustment device 4 are both retracted and not working, the overall height of the inner carrying platform 5 and the drone is lower than the outer carrying platform 1, and the drone is parked in the accommodation space formed by the outer carrying platform 1 and the inner carrying platform 5, which serves as a parking space for the drone, can reduce the space occupied by the drone lifting platform and improve the utilization rate of the space inside the vehicle.
[0092] When the UAV is ready to take off or land, the control system 8 controls the second lifting and adjusting device 4 to lift the inner carrying platform 5 and the UAV 7 up together until the inner carrying platform 5 rises to the same height as the outer carrying platform 1, and the control system 8 controls the third limiting member 408 to disconnect from the fourth limiting member 504, so that the inner carrying platform 5 and the fixed platform 401 of the second lifting and adjusting device 4 are separated; at the same time, the control system 8 controls the first limiting member 505 to lock with the second limiting member 6, so that the inner carrying platform 5 is rigidly fixed to the outer carrying platform 1. At this time, the inner load-bearing platform 5 and the outer load-bearing platform 1 start to be in the first working position, the second lifting and adjusting device 4 stops moving, and the control system 8 controls the first lifting and adjusting device 3 to continue to drive the inner load-bearing platform 5 and the outer load-bearing platform 1 to rise together until they rise to the take-off or landing height of the drone; at the same time, during the lifting process of the drone lifting platform, the detection device 81 obtains the state data such as gravity, gravity acceleration, inclination angle and angular velocity on the apron 5, and sends it to the control system 8. The control system 8 controls the rise or fall of multiple first lifting and adjusting devices 3 to different heights through the calculation module and the control module, adjusts the height of the inner load-bearing platform 5 and the outer load-bearing platform 1 and always maintains a horizontal state, so that the drone can always take off or land in a stable and safe state at the position where the vehicle-mounted drone lifting platform is ready to take off or land.
[0093] Similarly, after the drone lands safely and smoothly on the vehicle-mounted drone lifting platform, the control system 8 continues to control the load-bearing platform 5 and the outer load-bearing platform 1 to continue to descend until they land at the initial height of the first lifting and adjusting device 3. At this time, the control system 8 controls the first limiter 505 and the second limiter 6 to separate from each other, so that the inner load-bearing platform 5 is disconnected from the outer load-bearing platform 1, and the control system 8 controls the third limiter 408 and the fourth limiter 504 to lock, so that the inner load-bearing platform 5 is fixedly connected to the fixed platform 401 of the second lifting and adjusting device 4. At this time, the first lifting and adjusting device 3 stops working, the outer load-bearing platform 1 and the first lifting and adjusting device 3 return to the initial position, and the control system 8 continues to control the second lifting and adjusting device 4 to drive the inner load-bearing platform 5 and the drone to continue to descend, until they descend to the initial position of the second lifting and adjusting device 4 and end.
[0094] The vehicle according to an embodiment of the present application includes the above-mentioned drone lifting platform.
[0095] Specifically, the structure and function of this type of drone lifting platform can save the layout space of the vehicle-mounted drone cabin, so that the vehicle-mounted drone cabin is not restricted by the structure and can be arranged in multiple positions of the vehicle; and the drone lifting platform is adjusted through the control system 8 to keep the drone lifting platform in a horizontal position at all times, which can prevent the drone from taking off or landing during operation due to the vehicle being bumped or shaken, or the vehicle being driven on a slope, causing the drone lifting platform to also be bumped, shaken or tilted, thereby causing the drone to fail to take off or land or be damaged due to bumps, thereby ensuring that the drone can take off or land smoothly and safely no matter what environment it is in.
