[0035] The following will combine with the drawings to make a detailed description of a preferred embodiment of the present utility model.

[0036] Refer to Figures 1 to 2 , a lifting device for an unmanned aerial vehicle parking lot provided by the present utility model includes a bottom plate 1, a top plate 2, a lifting and positioning mechanism, a sliding and matching mechanism 4, and a driving mechanism 5. The bottom plate 1 and the top plate 2 are arranged oppositely and are movably connected through the lifting and positioning mechanism. The directions of the two midlines perpendicular to each other on the top surface of the bottom plate 1 are respectively the X-axis direction and the Y-axis direction.

[0037] Among them, the lifting and positioning mechanism is arranged between the bottom plate 1 and the top plate 2, and includes two groups of lifting assemblies 3 symmetrically arranged on both sides of the X-axis direction. Each group of lifting assemblies 3 includes support arms arranged in a mirror image. The middle parts of the two support arms are hinged in a cross shape. The upper ends of the cross-shaped support arms are movably connected to the bottom surface of the top plate 2, and the lower ends of the cross-shaped support arms are movably connected to the top surface of the bottom plate 1. And because the middle parts of the two support arms are hinged, the opposite ends of the two support arms can approach or move away from each other.

[0038] There are two groups of sliding and matching mechanisms 4, and the two groups of sliding and matching mechanisms 4 are respectively symmetrically arranged on the opposite side surfaces of the bottom plate 1 and the top plate 2. Each group of sliding and matching mechanisms 4 includes two guide rails 41 symmetrically arranged on both sides of the X-axis direction, and two slide blocks 42 respectively sliding on the guide rails 41; and the upper end of one support arm of each group of lifting assemblies 3 is movably connected to the top plate 2, and the lower end is movably connected to the slide block 42 located on the bottom plate 1; the upper end of the other support arm is movably connected to the slide block 42 on the top plate 2, and the lower end is movably connected to the bottom plate 1.

[0039] The driving mechanism 5 is arranged on the bottom plate 1 and includes a motor 51 and a lead screw module arranged along the X-axis direction and connected to the motor 51. Two sliders 42 on the bottom plate 1 are arranged on the lead screw module. The motor 51 is used to drive the lead screw module to rotate and synchronously drive the two sliders 42 on the bottom plate 1 to move on the guide rail 41. The lower ends of the two support arms connected to the two sliders 42 synchronously can move in the X-axis direction to approach or move away from the lower ends of the remaining two support arms. At the same time, since the upper ends of the remaining two support arms are connected to the sliders on the top plate, they move synchronously with the lower ends of the two support arms, so that the top plate 2 makes a lifting motion.

[0040] In this utility model, by arranging a sliding and matching mechanism on the top plate and the bottom plate, the cross-shaped support arms are connected to the sliding and matching mechanism, and the lead screw module is driven by a motor to move back and forth to realize the stable lifting of the top plate. The overall structure is simple, and the lifting process is stable and fast.

[0041] Further, for the convenience of describing the two sets of lifting components 3, two relatively close support arms are defined as inner support arms 31, and the remaining two support arms are defined as outer support arms 32.

[0042] Two bearing seat pads 33 are respectively arranged on the opposite sides of the bottom plate 1 and the top plate 2. The four bearing seat pads 33 are respectively arranged corresponding to the extending directions on the positive X-axis sides of the four guide rails 41. Double bearings 34 are respectively arranged on the four bearing seat pads 33. The lower ends of the two inner support arms 31 are respectively connected to the two double bearings 34 on the bottom plate 1. The upper ends of the two outer support arms 32 are respectively connected to the two double bearings 34 on the top plate 2.

[0043] Each set of sliding and matching mechanism 4 further includes a sliding connection plate 43 arranged along the Y-axis direction and fixedly connected to the two sliders 42 at both ends. Tail side shaft seats 44 are respectively arranged at both ends of the sliding connection plate 43 along the Y-axis direction.

[0044] The upper ends of the two inner support arms 31 are respectively connected to the two tail side shaft seats 44 on the top plate 2. The lower ends of the two outer support arms 32 are respectively connected to the two tail side shaft seats 44 on the bottom plate 1. During the lifting process of the top plate 2, the setting of the double bearings 34 and the tail side shaft seats 44 facilitates the rotation of the ends of the support arms, thus preventing jamming when the support arms move. In addition, by arranging the guide rail 41, the movement process of each mechanism is more stable.

[0045] Further, the lead screw module includes a lead screw 52 and a lead screw nut 53. The lead screw 52 is arranged along the X-axis direction, and its two ends are respectively rotatably installed on the fixed seats 11 on the bottom plate 1 through bearings. The lead screw nut 53 is sleeved on the lead screw 52. Connecting shafts 54 are respectively provided at both ends of the lead screw nut 53 along the Y-axis direction, and both ends of the connecting shafts 54 are respectively connected to two tail side seats 44 of the sliding connecting plate 43 on the bottom plate 1. That is, when the motor 51 drives the lead screw 52 to rotate to drive the lead screw nut 53 to move, the sliding connecting plate 43 is also driven to move. The lower ends of the outer support arms 32 are respectively connected to the sliding connecting plate 43, which can make the two outer support arms 32 move synchronously and stably, ensuring the stability of the lifting assembly during operation, and thus ensuring the smooth lifting of the top plate.

[0046] In addition, a limit block 12 is provided on the bottom plate 1. The limit block 12 is arranged outside one of the guide rails 41 and is close to one end of the lower end of the corresponding inner support arm 31. That is, the limit block 12 is used to limit the maximum moving distance of the sliding connecting plate 43 arranged on the bottom plate 1 on the guide rail. This moving distance is associated with the rising height of the top plate 2. By setting the limit block 12, while ensuring the rising height of the top plate 2, it also prevents the lead screw nut from moving to the critical position of the lead screw and getting stuck.

[0047] Further, the present utility model provides two embodiments for the specific structure of the support arm.

[0048] Embodiment 1, refer to Figure 3 .

[0049] The support arm includes a support arm main body 3.1. Both ends of the support arm main body 3.1 are bent in opposite directions at a set angle to respectively form an upper pivot end 3.2 and a lower pivot end 3.3. The upper pivot end 3.2 is movably connected to the top plate 2, and the lower pivot end 3.3 is movably connected to the bottom plate 1. The middle parts of the support arm main bodies 3.1 of the two support arms are hinged through a pin shaft 30. Pivot holes 3.4 are respectively provided on the upper pivot end 3.2 and the lower pivot end 3.3, and arc portions 3.5 concentric with the pivot holes 3.4 at the corresponding ends are respectively provided at the end parts of the upper pivot end 3.2 and the lower pivot end 3.3.

[0050] The present utility model bends both ends of the support arm main body 3.1 in opposite directions by 142° to form the upper pivot end 3.2 and the lower pivot end 3.3, which can decompose the gravity of the drone acting on the top plate 2 to the support arm main body and the pivot end, thereby ensuring that the support arm moves lightly and quickly during operation and can extend the service life of each mechanism.

[0051] A plurality of waist-shaped slot holes 3.6 are arranged at intervals along the length direction of the support arm main body 3.1 to reduce the weight of the support arm.

[0052] Embodiment 2, refer to Figure 4 .

[0053] Based on the principle of force decomposition, on the basis of Embodiment 1, the main body 3.1 of the support arm in this embodiment is provided with a hinged part body 3.1.1. Both ends of the hinged part 3.1.1 are bent in opposite directions at a set angle of 135°, respectively forming an upper support part 3.1.2 and a lower support part 3.1.3. And the upper pivot end 3.2 and the lower pivot end 3.3 are respectively arranged at the ends of the upper support part 3.1.2 and the lower support part 3.1.3. In addition, the bending direction of the upper support part 3.1.2 is opposite to that of the upper pivot end 3.2 but the bending angles are the same, both being 135°; the bending direction of the lower support part 3.1.3 is opposite to that of the lower pivot end 3.3 but the bending angles are the same, both being 135°, so that the support arm has a stepped integral structure, and the gravity of the drone is decomposed at each stage of the support arm, further improving the lifting speed, while also ensuring the stability of the lifting process and improving the stability of the overall structure of the device.

[0054] In summary, for the drone parking lot lifting device provided by the present utility model, by arranging a sliding mechanism on the top plate and the bottom plate, the cross-shaped support arm is connected to the sliding mechanism, and the motor drives the screw module to move back and forth to realize the stable lifting of the top plate. The overall structure is simple, and the lifting process is stable and fast; by setting the support arm to a specific structure, the overall stability of the device is improved, and the service life of each mechanism is also improved.

[0055] In the above description, many specific details are elaborated to fully understand the present utility model. However, the above description is only the preferred embodiment of the present utility model. The present utility model can be implemented in many other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed above.
