Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, and in particular to a drone platform, a drone hangar, and a vehicle. Background Technology

[0002] In recent years, the drone industry has developed rapidly, and vehicle-mounted drones, as an inevitable product of technological development, have an increasingly wide range of applications. Drone platforms, serving as take-off and landing platforms for drones, can be mounted on vehicles, ships, and building walls, among other things. As drones become larger, the corresponding drone platforms also become larger.

[0003] In related technologies, a forklift lifting mechanism generally consists of two symmetrically arranged forklift arms, a motor that drives the forklift arms to lift, and a lifting platform mounted on top of the lifting mechanism. In this structure, the driving force required for the lifting mechanism to lift from the bottom is very large, which may place an excessive burden on the drive motor, significantly reducing the motor's lifespan.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0055] Please see Figures 1 to 4This utility model provides a drone platform 100, which includes a fixed base 1, a lifting device 2, a load-bearing component 3, and an elastic element 4. The lifting device 2 is disposed on the fixed base 1. The load-bearing component 3 is disposed on the lifting device 2 and can move relative to the fixed base 1. The load-bearing component 3 is used to carry the drone. When the lifting device 2 drives the load-bearing component 3 to lift relative to the fixed base 1, the elastic element 4 is used to provide tension for the lifting device 2. The tension is used to assist the lifting device 2 in driving the load-bearing component 3 to lift.

[0056] In the drone platform 100 of this application embodiment, the drone platform 100 includes a fixed base 1, a lifting device 2, a load-bearing component 3, and an elastic element 4; the lifting device 2 is disposed on the fixed base 1; the load-bearing component 3 is disposed on the lifting device 2 and is movable relative to the fixed base 1, and the load-bearing component 3 is used to carry the drone; when the lifting device 2 drives the load-bearing component 3 to lift relative to the fixed base 1, the elastic element 4 is used to provide tension to the lifting device 2, and the tension is used to assist the lifting device 2 in driving the load-bearing component 3 to lift. In this way, the elastic element 4 can assist the movement of the lifting device 2, avoid the motor 231 of the lifting device 2 from independently undertaking the driving process, and improve the life of the motor 231.

[0057] In related technologies, the increased load on the drone platform leads to an increase in the motor driving force, and the motor driving rate varies greatly during the lifting and landing processes.

[0058] In some embodiments, the tension of the elastic element 4 is negatively correlated with the height of the lifting device 2. Thus, during the lifting process, the tension of the elastic element 4 decreases, and during the descent, the tension gradually increases, allowing the elastic element 4 to act as a buffer to assist the movement of the lifting device 2. This avoids the motor 231 bearing the entire weight of the lifting device 2's movement, thereby extending the motor 231's lifespan.

[0059] Specifically, the drone can take off from the carrier assembly 3; or land on the carrier assembly 3 and remain there, moving with the carrier assembly 3. The carrier assembly 3 is connected to the fixed base 1 via a lifting device 2, which can drive the carrier assembly 3 to move vertically relative to the fixed base 1. The elastic element 4 assists the lifting device 2, providing lift when it drives the carrier assembly 3 to rise, preventing the motor 231 of the lifting device 2 from bearing the entire driving process independently and extending its lifespan. Simultaneously, when the carrier assembly 3 descends, the elastic element 4 can also hold it in place, providing a buffer during descent and preventing damage to the drone from excessively rapid descent.

[0060] Thus, when the drone is mounted on the drone platform 100, driven by the motor 231 and assisted by the elastic element 4, the drone can move upward with the support component 3, rising above the position of the fixed base 1, facilitating takeoff. When the drone is finished and needs to be retrieved, it can land on the support component 3, allowing it to return to the position of the fixed base 1 along with the support component 3. During this process, the elastic element 4 is stretched again, providing cushioning force for the descent of the support component 3. Of course, during the drone's operation, the support component 3 does not need to be constantly exposed; it can be retracted first, and then extended again after the drone has finished its work to retrieve it.

[0061] In some embodiments, the elastic element 4 is a tension spring, with its two ends connected to the fixed base 1 and the lifting device 2 respectively and in a pre-stretched state. Thus, the tension spring is always in a stretched state, and its tension can assist in lifting the bearing assembly 3 while providing a buffer force for lowering the bearing assembly 3.

[0062] In some embodiments, the elastic member 4 is disposed in the receiving groove 11; the first slider assembly 22 is at least partially disposed in the receiving groove 11; the first connecting portion 111 and the second connecting portion 222 of the fixing seat 1 are disposed in the receiving groove 11; the first end of the elastic member 4 is connected to the first connecting portion 111, and the second end of the elastic member 4 is connected to the second connecting portion 222 of the first slider assembly 22.

[0063] Thus, the elastic element 4 can be compressed or stretched within the receiving groove 11 to store elastic potential energy to assist the movement of the lifting device 2.

[0064] Specifically, the fixing base 1 includes a receiving groove 11 and a first connecting part 111 disposed within the receiving groove 11. The first connecting part 111 is fixedly disposed at one end within the receiving groove 11. The elastic member 4 is also disposed within the receiving groove 11. The space within the receiving groove 11 provides sufficient space for the installation of the elastic member 4, facilitating the compression or stretching of the elastic member 4 within a specific space, so that the operation of the elastic member 4 is not affected by other components.

[0065] Furthermore, the first end of the elastic element 4 is connected to the first connecting part 111, so that the first end of the elastic element 4 is fixed in one end within the receiving groove 11. In this way, when the other end of the elastic element 4 is connected to a movable component, the elastic element 4 can store or release elastic potential energy during the movement of the movable component, so that the elastic element 4 can assist the movement of the lifting device 2, avoid the motor 231 of the lifting device 2 from independently undertaking the driving process, and improve the life of the motor 231.

[0066] In some embodiments, the lifting device 2 includes a linkage mechanism 21 and a first slider assembly 22 connected together. The first slider assembly 22 is movably disposed on the fixed base 1. When the first slider assembly 22 moves along a first direction between a first position and a second position, it can drive the linkage mechanism 21 to lift or lower the bearing assembly 3. The first end of the elastic member 4 is connected to the fixed base 1, and the second end of the elastic member 4 is connected to the first slider assembly 22. The sliding direction of the first slider assembly 22 is consistent with the stretching direction of the elastic member 4.

[0067] In this way, the driving force along the lifting device 2 in the first direction can be converted into the force that drives the bearing assembly 3 to rise and fall, while the elastic element 4 assists the lifting and falling of the bearing assembly 3.

[0068] Specifically, the second end of the elastic element 4 is connected to the first slider assembly 22. When the first slider assembly 22 slides, it drives the elastic element 4 to store or release elastic potential energy, so that the elastic element 4 can assist the movement of the first slider assembly 22 and the linkage mechanism 21.

[0069] For example, when the supporting component 3 needs to be lifted at its lowest point, the first slider assembly 22 is in the second position, and the elastic component is in a stretched state. When the first slider assembly 22 slides into the receiving groove 11 along the first direction and reaches the first position, the elastic element 4 releases its elastic potential energy in a timely manner. The elastic potential energy further pulls the first slider assembly 22 into the receiving groove 11. This movement of the first slider assembly 22 drives the linkage mechanism 21 to lift the supporting component 3. In this way, the elastic element 4 can assist the linkage mechanism 21 in lifting the supporting component 3 while pulling the first slider assembly 22 to move.

[0070] Alternatively, when the supporting component 3 needs to be lowered from its highest point, the first slider assembly 22 is in the first position. The first slider assembly 22 slides at least partially out of the receiving groove 11 along the first direction and slides to the second position. In this way, when the first slider assembly 22 moves, it drives the linkage mechanism 21 to lower the supporting component 3. Simultaneously, the first slider assembly 22 also stretches the elastic element 4, allowing the elastic element 4 to store elastic potential energy for the next lifting of the supporting component 3. Furthermore, the elastic element 4 also provides a buffering force for the descent of the supporting component 3 during the storage of elastic potential energy.

[0071] It should be noted that the embodiments of this application do not limit the way the elastic element 4 stores elastic potential energy. For example, the elastic element 4 can be stretched to store elastic potential energy, or the elastic element 4 can be compressed to store elastic potential energy, or both compression and stretching can be used to store elastic potential energy to meet various needs.

[0072] Please see Figure 1 and Figure 2In some embodiments, the linkage mechanism 21 includes a first link 211 and a second link 212. The middle part of the first link 211 and the middle part of the second link 212 are hinged together. The two ends of the first link 211 are respectively hinged to the fixed base 1 and the bearing assembly 3, and the two ends of the second link 212 are respectively hinged to the bearing assembly 3 and the first slider assembly 22.

[0073] Thus, the hinged arrangement between the first link 211 and the second link 212 allows the link mechanism 21 to deform and change its height, so that the load-bearing component 3 can be smoothly raised or lowered by the link mechanism 21.

[0074] Specifically, the middle part of the first link 211 and the middle part of the second link 212 are hinged together, so that the first link 211 and the second link 212 can rotate within a certain range around the middle hinge point (similar to the two parts of scissors being able to rotate around the middle hinge point), so that the first link 211 and the second link 212 can form an "X-shaped" linkage mechanism 21.

[0075] Furthermore, the two ends of the first link 211 are respectively hinged to the fixed base 1 and the bearing assembly 3, and the two ends of the second link 212 are respectively hinged to the bearing assembly 3 and the first slider assembly 22, so that the tilt angle change of the "X-shaped" link mechanism 21 relative to the fixed base 1, the bearing assembly 3 and the first slider assembly 22 due to deformation can be allowed.

[0076] For example, when the first slider assembly 22 slides into the receiving groove 11 along the first direction, the first slider assembly 22 pushes one corner of the "X-shaped" linkage mechanism 21, so that the linkage mechanism 21 changes from a wide and flat "X-shaped" (similar to the two blades of upright scissors fully open) to a narrow and tall "X-shaped" (similar to the two blades of upright scissors mostly closed), while driving the bearing assembly 3 to rise.

[0077] Alternatively, when the first slider assembly 22 slides at least partially out of the receiving groove 11 along the first direction, the first slider assembly 22 pulls one corner of the "X-shaped" linkage mechanism 21, causing the linkage mechanism 21 to change from a slender and tall "X-shape" to a wide and flat "X-shape", while simultaneously driving the bearing assembly 3 to descend.

[0078] It should be noted that the hinge connection between the middle of the first connecting rod 211 and the middle of the second connecting rod 212 can employ a combination of flat-head rivets and bushings. The bushing can be a component combining a metal substrate with a polytetrafluoroethylene (PTFE) coating, with a bushing wall thickness of 1mm. This ensures flexible rotation of the hinged parts while enhancing their wear resistance. Additionally, oil-impregnated bearings are installed at other hinged locations. These bearings, made from sintered bodies produced by powder metallurgy, provide lubrication, resulting in smoother and quieter operation of the lifting device 2.

[0079] Please see Figure 1 In some embodiments, the support assembly 3 includes a support platform 31 and a second slider assembly 32. The second slider assembly 32 is movably disposed on the support platform 31, which is used to support the drone. The end of the first link 211 or the second link 212 away from the fixed base 1 is hinged to the second slider assembly 32.

[0080] In one embodiment, the two ends of the first connecting rod 211 are respectively hinged to the fixed base 1 and the second slider assembly 32, and the first slider assembly 22 and the second slider assembly 32 move in the same direction.

[0081] In another embodiment, the two ends of the second link 212 are respectively hinged to the bearing assembly 3 and the second slider assembly 32, and the first slider assembly 22 and the second slider assembly 32 move in opposite directions.

[0082] Thus, the first slider assembly 22 and the second slider assembly 32 cooperate to allow the upper and lower corners of the "X-shaped" linkage mechanism 21 to move synchronously and in the same direction, thereby causing the linkage mechanism 21 to deform and simultaneously driving the support platform 31 to rise or fall.

[0083] Specifically, when the "X-shaped" linkage 21 changes between two forms, wide and flat and slender, the width of the upper and lower ends of the "X" must change synchronously.

[0084] Furthermore, since the first link 211 and the second link 212 are hinged together in the middle to form an "X" shape, when the upper end of the first link 211 is on the left, the lower end of the second link 212 must also be on the left, and vice versa. The lower end of the first link 211 is hinged to the fixed base 1, and the upper end is hinged to the second slider assembly 32; the lower end of the second link 212 is hinged to the first slider assembly 22, and the upper end is hinged to the support platform 31. Therefore, only one side of the "X-shaped" linkage mechanism 21 can move along the first direction; that is, only the upper end of the first link 211 and the lower end of the second link 212 can move. And because the linkage mechanism 21 is similar to scissors, the width of the upper and lower ends of the linkage mechanism 21 will change synchronously. In other words, the movement of the first slider assembly 22 and the second slider assembly 32 is synchronized.

[0085] For example, when the first slider assembly 22 slides into the receiving groove 11, it pushes the second connecting rod 212, causing the lower end of the "X-shaped" connecting rod mechanism 21 to narrow, which in turn causes the upper end of the "X-shaped" connecting rod mechanism 21 to also narrow, thus moving the second slider assembly 32. In this way, the sliding direction of the first slider assembly 22 is the same as that of the second slider assembly 32. This converts the horizontal force of the first slider assembly 22 into a vertical force of the connecting rod mechanism 21, thereby causing the support platform 31 to rise or fall.

[0086] Please see Figure 1 and Figure 2 In some embodiments, the first slider assembly 22 includes a second connecting portion 222 and a hinged connecting portion 221. The second connecting portion 222 is disposed in the receiving groove 11 and is used to connect the second end of the elastic member 4. The hinged connecting portion 221 is hinged to one end of the second connecting rod 212.

[0087] When the first slider assembly 22 is in the second position, the second link 212 and the first link 211 avoid the elastic element 4.

[0088] In this way, the elastic element 4 and the second connecting rod 212 are indirectly connected, and the elastic element 4 is ensured to work only within the receiving groove 11, avoiding being affected by other components.

[0089] Specifically, the elastic element 4 is disposed within the receiving groove 11, and the first slider assembly 22 is at least partially disposed within the receiving groove 11, with at least a portion of the first slider assembly 22 capable of sliding along a first direction within the receiving groove 11. The first end of the elastic element 4 is connected to the first connecting portion 111 of the receiving groove 11, and the second end is connected to the second connecting portion 222 of the first slider assembly 22 within the receiving groove 11. The second end can move with the first slider assembly 22, thereby stretching or compressing the elastic element 4. Simultaneously, the end of the first slider assembly 22 located outside the receiving groove 11 is provided with a hinged connecting portion 221, which is connected to the lower end of the second connecting rod 212, allowing the relative angle between the first slider assembly 22 and the second connecting rod 212 to vary.

[0090] For example, when the supporting component 3 is lowered, the first slider assembly 22 is in the second position. To prevent the elastic element 4 from being affected by other components (such as the first connecting rod 211 and the second connecting rod 212), the second connecting rod 212 and the first connecting rod 211 should be misaligned with the elastic element 4. This ensures that the stretching or rebound of the elastic element 4 is only related to the movement of the first slider assembly 22, increasing the reliability of the lifting device 2.

[0091] Please see Figure 1 and Figure 2 In some embodiments, there are two linkage mechanisms 21, and the two linkage mechanisms 21 are arranged on both sides of the fixed base 1 along the second direction;

[0092] The first direction and the second direction are perpendicular.

[0093] In this way, the four links of the two linkage mechanisms 21 can support the four corners of the support platform 31 respectively, so as to smoothly raise or lower the support platform 31.

[0094] Specifically, both the overall shape of the support platform 31 and the overall shape of the fixed base 1 are rectangular. One linkage mechanism 21 can only support the two ends of one side of the rectangular support platform 31, and this side is parallel to the first direction. The opposite side of this side is also parallel to the first direction, and the opposite side is supported by a second linkage mechanism 21. The two linkage mechanisms 21 are also connected to the corresponding four corners of the fixed base 1. In this way, the support platform 31 can be raised and lowered smoothly with the support of the two linkage mechanisms 21.

[0095] Furthermore, two linkage mechanisms 21 can be connected to both sides of the first slider assembly 22 simultaneously, so that the two linkage mechanisms 21 can move synchronously with the first slider assembly 22, thereby ensuring that the support platform 31 can be raised or lowered smoothly.

[0096] Please see Figure 1 and Figure 2In some embodiments, the linkage mechanism 21 further includes a first limiting rod 213 and a second limiting rod 214. The first limiting rod 213 is disposed on the first link 211 and extends from the first link 211 toward a position close to the bearing component 3. The second limiting rod 214 is disposed on the second link 212 and extends from the second link 212 toward a position close to the bearing component 3.

[0097] When the first slider assembly 22 is in the second position, the first limiting rod 213 and the second limiting rod 214 protrude from the bearing assembly 3 and limit the propeller of the UAV.

[0098] Thus, when the drone retracts to the drone platform 100, the first limit rod 213 and the second limit rod 214 limit and retract the drone's propellers to prevent damage caused by free swinging.

[0099] Specifically, when the drone retracts the drone platform 100 and the carrier platform 31 descends, the two first limit rods 213 and the two second limit rods 214 of the two linkage mechanisms 21 slowly rise relative to the carrier platform 31 and continue to extend through the carrier platform 31. The four extended limit rods limit and retract the four propellers of the drone respectively, preventing the drone propellers from being damaged due to free swing when the vehicle 300 moves.

[0100] At the same time, when the support platform 31 rises, the first limit rod 213 and the second limit rod 214 slowly descend relative to the support platform 31, canceling the limit and convergence of the drone propeller, making it easier for the drone to fly out of the drone platform 100.

[0101] Please see Figure 1 In some embodiments, the support component 3 is formed with a relief groove 33, and when the first slider component 22 is in the second position, the first limiting rod 213 and the second limiting rod 214 protrude from the support component 3 through the relief groove 33.

[0102] In this way, the first limiting rod 213 and the second limiting rod 214 can pass through the bearing component 3, which facilitates the limiting and retraction of the drone's propellers.

[0103] Specifically, the support component 3 has a clearance groove 33. When the support component 3 descends, the first limiting rod 213 and the second limiting rod 214 slowly rise relative to the support component 3 and pass through the clearance groove 33, ultimately causing the first limiting rod 213 and the second limiting rod 214 to protrude from the support component 3. At the same time, during the rising process of the first limiting rod 213 and the second limiting rod 214, the propeller of the UAV is limited and brought together.

[0104] Please see Figure 1 and Figure 3In some embodiments, the lifting device 2 further includes a drive component 23, which is connected to the first slider component 22 and drives the first slider component 22 to move relative to the fixed seat 1 between a first position and a second position.

[0105] In this way, the drive component 23 can drive the first slider component 22 to move, thereby driving the support component 3 to rise and fall.

[0106] Specifically, the drive component 23 can be a component such as a motor 231 that can provide controllable driving force. The drive component 23 can be driven to the first slider component 22 through components such as gears and shafts, so that the driving force of the drive component 23 can be transmitted to the first slider component 22, so that the first slider component 22 can move between the first position and the second position relative to the fixed seat 1.

[0107] Figure 4 This diagram illustrates the stroke and driving force of motor 231, showing the difference in driving force between motor 231 without and with elastic element 4. It is clearly visible that after elastic element 4 is installed in the lifting device 2, the driving force of the motor 231 lead screw is significantly reduced.

[0108] The embodiments of this application do not limit the type of the driving component 23 or the driving connection method between the driving component 23 and the first slider component 22, so as to meet various needs.

[0109] Please see Figure 1 and Figure 3 In some embodiments, the drive assembly 23 is disposed on the fixed base 1, and in a first direction the drive assembly 23 is located on the side of the first slider assembly 22 away from the linkage mechanism 21.

[0110] Thus, by placing the drive assembly 23 at the edge of the fixed base 1 and close to the first slider assembly 22, it is convenient for the drive assembly 23 to drive the first slider assembly 22 to move, while avoiding mutual interference between the drive assembly 23 and the linkage mechanism 21.

[0111] Specifically, in the first direction, the drive component 23 is located on the side of the first slider component 22 away from the linkage mechanism 21. That is, the midpoint of the projection of the drive component 23 in the second direction is close to the projection of the first slider component 22, and the midpoint of the projection of the drive component 23 in the second direction is not within the projection of the linkage mechanism 21. The embodiments of this application do not limit the number of drive components 23 to meet various needs.

[0112] Please see Figure 1 and Figure 3In some embodiments, the drive assembly 23 includes a motor 231 and a lead screw mechanism 232 connected to the motor 231. The motor 231 is mounted on the fixed base 1, and the lead screw mechanism 232 is connected to the first slider assembly 22. The motor 231 drives the first slider assembly 22 to move relative to the fixed base 1 through the lead screw mechanism 232. The axial direction of the lead screw mechanism 232 is the same as the sliding direction of the first slider assembly 22.

[0113] In this way, the motor 231 can drive the first slider assembly 22 to move relative to the fixed seat 1 through the lead screw mechanism 232.

[0114] Specifically, motor 231 is connected to lead screw mechanism 232. When motor 231 rotates, lead screw mechanism 232 converts the rotational motion of motor 231 into linear motion, allowing lead screw mechanism 232 to move along its own axis (first direction). Simultaneously, because lead screw mechanism 232 is connected to first slider assembly 22, and the axis of lead screw mechanism 232 is the same as the sliding direction (first direction) of first slider assembly 22, motor 231 drives lead screw mechanism 232, which in turn drives first slider assembly 22, allowing first slider assembly 22 to slide relative to fixed base 1 along the first direction.

[0115] The embodiments of this application do not limit the type of motor 231 in the drive assembly 23. The motor 231 can be of various types, such as an axial motor and a linear motor, to meet various needs.

[0116] Please see Figures 5 to 8 In some embodiments, the first slider assembly 22 includes a rotating rod structure and a slider 225. The rotating rod structure includes at least two rotating rods, which are hinged to each other. The two ends of the rotating rod structure are respectively hinged to the fixed seat 1 and the slider 225. The driving assembly 23 is connected to and drives the slider 225 to move along the first direction. The linkage mechanism 21 is hinged to the slider 225.

[0117] For example, the first slider assembly 22 includes a first rotating rod 223, a second rotating rod 224 and a slider 225. The first rotating rod 223 is hinged to the second rotating rod 224. The end of the first rotating rod 223 away from the second rotating rod 224 is hinged to the fixed base 1, and the end of the second rotating rod 224 away from the first rotating rod 223 is hinged to the slider 225.

[0118] Of course, in other embodiments, the rotating rod structure may include other numbers of rotating rods, which are not limited here, to meet different needs. The following description uses the first rotating rod 223 and the second rotating rod 224 as examples.

[0119] In this way, the rotational torque of the motor 231 can be converted into the linear power of the slider 225, so that the slider 225 can reciprocate without changing the rotation direction of the motor 231. At the same time, the first rotating rod 223 and the second rotating rod 224 can limit the sliding range of the slider 225, thereby increasing the stability of the sliding of the first slider assembly 22.

[0120] Specifically, the motor 231, connected to the slider 225, provides torque to the first rotating rod 223, driving it to rotate around the hinge point with the fixed base 1. The first rotating rod 223 then drives the second rotating rod 224 to rotate around the hinge point between the first and second rotating rods 223 and 224, changing the relative angle between them and altering the distance between their farthest points. Thus, the slider 225, hinged to the second rotating rod 224 at the end of the second rotating rod 224 furthest from the first rotating rod 223, moves along a first direction. In this way, the motor 231 can convert the rotational motion into a reciprocating motion similar to piston motion.

[0121] In this embodiment, the first rotating rod 223 and the second rotating rod 224 are hinged together, and the connecting rod formed by the first rotating rod 223 and the second rotating rod 224 realizes the horizontal movement of the pushing block. At the same time, when lifting to the highest position and lowering to the lowest position, the first rotating rod 223 and the second rotating rod 224 will be linearly aligned, making the lifting device 2 more stable.

[0122] Furthermore, due to the length limitations of the first and second rotating rods, the reciprocating motion range of the slider 225 is restricted, and it can only slide between the first and second positions.

[0123] Please see Figure 1 In some embodiments, the fixing base 1 further includes a limiting block 12, which is used to abut against the first slider assembly 22 when the first slider assembly 22 moves to the first position.

[0124] This prevents the first slider assembly 22 from sliding out of the receiving groove 11 and causing the drone platform 100 to malfunction.

[0125] Specifically, the fixed base 1 is provided with a limiting block 12, which is positioned in the direction of the sliding out of the receiving groove 11 of the first slider assembly 22. The limiting block 12 is used to limit the sliding distance of the first slider assembly 22, so that the first slider assembly 22 is at least partially located within the receiving groove 11. At the same time, it limits the lifting and lowering degree of the bearing assembly 3, leaving space for other components on the fixed base 1 and preventing the bearing assembly 3 from falling too low and affecting the normal operation of other components on the fixed base 1.

[0126] For example, when the support component 3 is lifted under the indirect drive of the motor 231, the first slider component 22 is resisted by the limiting block 12 set on the fixed seat 1 when it slides to the first position, preventing the first slider component 22 from sliding completely into the receiving groove 11, and at the same time limiting the lifting degree of the support component 3, so as to ensure the stable operation of the UAV platform 100.

[0127] Please see Figure 3 and Figure 9 In some embodiments, the fixed base 1 further includes a slide rail 13, and the first slider assembly 22 is disposed on the slide rail 13 and slides along the slide rail 13 between a first position and a second position.

[0128] Thus, the slide rail 13 can limit the sliding direction of the first slider assembly 22 and allow the first slider assembly 22 to slide smoothly between the first position and the second position, ensuring the stable operation of the lifting device 2.

[0129] Please see Figure 9 In some embodiments, the first slider assembly 22 includes a slider 225 and a roller 226. The slider 225 has a groove 227 formed on the side near the slide rail 13, and the roller 226 is disposed in the groove 227 and can roll relative to the slide rail 13.

[0130] Thus, the slide groove 227 and the slide rail 13 can limit the sliding direction of the first slider assembly 22, and the roller 226 can reduce the friction when the first slider assembly 22 slides, so that the sliding of the first slider assembly 22 is smooth and stable.

[0131] Specifically, the groove 227 on the slider 225 of the first slider assembly 22 engages with the slide rail 13 on the fixed base 1, allowing the slide rail 13 to restrict the sliding of the first slider assembly 22 along the first direction. Simultaneously, the roller 226 of the first slider assembly 22 is disposed between the groove 227 and the slide rail 13, ensuring that the first slider assembly 22 generates only rolling friction with less friction force during movement, thus guaranteeing smooth sliding of the first slider assembly 22.

[0132] It should be noted that roller 226 can be made of Cr15 steel (high carbon chromium bearing steel) and PTFE material, with the plastic layer thickness being 0.5mm (tolerance 0 / -0.04mm) and possessing good wear resistance. This helps reduce abnormal noise when slider 225 slides.

[0133] Please see Figure 1 and Figure 2 In some embodiments, the elastic element 4 is a tension spring, with its two ends connected to the fixed base 1 and the lifting device 2 respectively and in a pre-stretched state.

[0134] Thus, the elastic element 4 is preferably a tension spring, which provides lifting auxiliary power for the lifting device 2 or buffering force when the lifting device 2 is lowered, while the installation of the tension spring is easier.

[0135] Furthermore, the specific type of the elastic element 4 is not limited in the embodiments of this application, as long as it is small and can stably and persistently provide elastic potential energy to meet various needs.

[0136] Please see Figure 1 and Figure 10 This application provides a drone hangar 200, including an engine and a drone platform 100 according to any of the above embodiments.

[0137] In this way, the drone platform 100 can be installed in the drone hangar 200, providing a shelter for the drone and the drone platform 100.

[0138] Specifically, the drone platform 100 installed in the drone hangar 200 is protected from wind, rain, sun and impacts, is dustproof and waterproof, extends the service life of the drone platform 100 and the drones therein, and provides energy supply for the drone platform 100 and the drones therein, making it convenient to move the drone platform 100 and the drones therein, and realizing multiple uses.

[0139] Please see Figure 11 This application provides a vehicle 300, which includes a drone platform 100 according to any of the above embodiments, or a drone hangar 200 according to any of the above embodiments.

[0140] In the drone platform 100 of this application embodiment, the drone platform 100 includes a fixed base 1; a lifting device 2 disposed on the fixed base 1; a load-bearing component 3 disposed on the lifting device 2 and movable relative to the fixed base 1, the load-bearing component 3 being used to carry the drone; and an elastic element 4, which provides tension to the lifting device 2 when the lifting device 2 drives the load-bearing component 3 to lift relative to the fixed base 1. This tension assists the lifting device 2 in driving the load-bearing component 3 to lift. Thus, the elastic element 4 can assist the movement of the lifting device 2, preventing the motor 231 of the lifting device 2 from independently undertaking the driving process and improving the lifespan of the motor 231.

[0141] Specifically, the vehicle 300 can be equipped with a drone platform 100 via a drone hangar 200, enabling the integration of drone and vehicle 300 functions and providing various possibilities for the use of both. For example, the drone can survey the surrounding terrain of the vehicle 300, locate roads, or perform self-driving aerial photography for entertainment. In this embodiment, the drone hangar 200 can be located at any position on the vehicle 300; for example, it can be located on top of the vehicle 300 or in the trunk, to meet different needs.

[0142] Furthermore, the vehicle 300 in this application embodiment can be a pure electric vehicle 300, a hybrid electric vehicle 300, a plug-in hybrid electric vehicle 300, a range-extended electric vehicle 300, a gasoline vehicle, etc. The vehicle 300 can also be a sedan, a truck, a bus, a lorry, a trailer, etc. This application does not specifically limit the type of vehicle 300.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
