Description

Technical Field

[0001] This invention relates to the field of anti-shake gimbal technology, specifically an anti-shake connection device for a drone and a surveying instrument. Background Technology

[0002] UAV aerial surveying is a powerful supplement to traditional aerial photogrammetry, featuring high mobility, efficiency, speed, precision, low operating costs, wide applicability, and short production cycles. It has significant advantages in rapidly acquiring high-resolution images of small areas and areas with difficult flight conditions. With the development of UAV and digital camera technologies, digital aerial photography technology based on UAV platforms has demonstrated its unique advantages. Mechanical image stabilization technology of UAV gimbals is widely used in aerial photography, environmental monitoring, and other fields. Its advantages lie in significantly improving the stability and clarity of captured images, reducing blurring and ghosting caused by shaking, and improving surveying accuracy. Existing image stabilization connection devices generally filter small vibrations and shakes through rubber balls or rubber pads, but they usually only reduce vibrations in one direction. The two ends of the gimbal are mostly in rigid contact or connection in other directions. Therefore, a UAV and surveying instrument image stabilization connection device with better image stabilization performance is proposed. Summary of the Invention

[0003] The purpose of this invention is to provide a shake-stabilizing connection device for a drone and a surveying instrument, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A shake-stabilization connection device for a drone and a surveying instrument, comprising:

[0006] Top end: Used for mounting and connecting with the drone;

[0007] Lower end: used to connect the surveying instrument, and multiple balloons are provided between the lower end and the upper end;

[0008] Upper support assembly: connected to the upper end, the upper support assembly has a magnetic block installed inside, and the upper support assembly presses the lower end downward through the magnetic block;

[0009] Lower support assembly: The structure is the same as the upper support assembly and it is located directly below the upper support assembly. The lower support assembly supports the lower end upward through the magnetic block inside it.

[0010] Flipping component: Used to flip the magnetic blocks on the upper and lower support components.

[0011] Furthermore, the upper end includes an upper seat plate, and four side support rods are fixedly connected to the outer side wall of the upper seat plate at equal angles in a ring. The bottom end of the side support rods is fixedly connected to a first receiving plate. The lower end includes a lower seat plate, and uprights are fixedly connected to both sides of the top surface of the lower seat plate. An annular frame is fixedly connected between the top ends of the two uprights. Four second receiving plates are fixedly connected to the outer side wall of the annular frame at equal angles in a ring. The four second receiving plates correspond one-to-one with the four first receiving plates. The number of balloons is four, and they are located between multiple sets of second receiving plates and first receiving plates.

[0012] Furthermore, a connecting frame is fixedly connected between the top ends of the two uprights, and a magnet is fixedly installed on the inner wall of the connecting frame, with the magnet located between the two magnetic blocks.

[0013] Furthermore, the sidewalls of the second receiving plate and the corresponding first receiving plate that are close to each other are arc-shaped, and the sidewall of the first receiving plate is provided with a platform.

[0014] Furthermore, the upper supporting component includes:

[0015] Fixing frame: Fixing plates are fixedly connected between the outer side walls on both sides and the upper base plate.

[0016] Horizontal frame: There are two horizontal frames, which are fixed on both sides of the fixed frame, and both ends of the fixed frame are fixedly connected to the sockets;

[0017] Outer sleeve: Both sides of one end are fixedly connected to shafts, one end of the shaft is fixedly sleeved with a gear, the inside of the gear is fixedly installed with a magnetic block, and the outer side wall of the shaft is slidably connected to the inner wall of the outer sleeve;

[0018] Tooth plates: There are two tooth plates, located above the transverse frame. The tooth plates are fixed to the fixed frame and mesh with the adjacent gear.

[0019] Furthermore, the flipping assembly includes two mounting plates, which are fixedly connected to the top surface of the fixing frame. Each end of the mounting plate is fixedly connected to a fixing lug. A lead screw is rotatably connected between the top ends of the two fixing lugs. An elongated groove is formed on the top surface of the mounting plate. An internal threaded seat is screwed onto the outer wall of the lead screw. A drive rod is fixedly connected to the bottom end of the internal threaded seat. The top end of the drive rod is slidably connected to the inner wall of the elongated groove. A sliding groove is formed on the outer wall of the drive rod. The shaft is slidably connected to the inner wall of the adjacent sliding groove. A transmission box is fixedly connected to one end of the fixing frame between the ends of the two lead screws. The two lead screws are synchronously driven through the transmission box. A drive motor is fixedly connected to one end of the fixing frame. The output end of the drive motor is connected to one end of a lead screw.

[0020] Furthermore, two screws are provided between the upper and lower receiving components, and both ends of the fixing frame are fixedly connected to sockets. The screws are slidably sleeved with the two adjacent sockets, and the top of the screws is screwed with a nut.

[0021] Furthermore, the distance from the centerline of the shaft to the center of the side of the outer sleeve is equal to one-quarter of the outer circumference of the gear.

[0022] Furthermore, the receiving plate and the upper seat plate are perpendicular to each other.

[0023] Furthermore, the distance from the transverse frame to the bottom surface of the upper seat plate is greater than the length of the outer kit.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] 1. By setting the lower end and using multiple balloons distributed around the ring frame, the horizontal direction of the lower end is buffered and limited. By setting the upper and lower support components, the magnetic blocks on the upper and lower support components simultaneously repel the magnets, thereby achieving non-contact support for the lower end through the lower support component. This achieves a non-rigid connection between the upper and lower ends, reducing the vibration transmitted from the upper end to the lower end, thereby reducing the shaking of the surveying instrument connected to the lower base plate caused by the UAV.

[0026] 2. By setting up the flip component, after the surveying is completed, the drive motor is started via a signal, and the drive rod pushes the shaft. Through the meshing between the gear and the toothed plate, when the shaft moves laterally, the gear drives the outer kit to flip, causing the outer kit to flip half a turn in place. This causes the magnetic blocks and magnets to change from a repulsive state to an attractive state, so that the two magnetic blocks and magnets are attracted together. This switches the lower end and the upper support component to a rigid connection, thereby reducing the impact of the surveying instrument's swing on the drone's attitude during drone transfer and facilitating operation. When the drone is moved into position and ready for surveying, the lower end and the upper support component switch back to a flexible connection state. Attached Figure Description

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0037] Please see Figures 1-4In this embodiment of the invention, a shake-stabilizing connection device for a drone and a surveying instrument includes an upper end 100 for connection to the drone, a lower end 500 for connection to the surveying instrument, a plurality of balloons 600 disposed between the lower end 500 and the upper end 100, an upper support component 200 connected to the upper end 100, a magnetic block installed inside the upper support component 200, the upper support component 200 pressing the lower end 500 downward through the magnetic block, a lower support component 300 having the same structure as the upper support component 200 and located directly below the upper support component 200, the lower support component 300 supporting the lower end 500 upward through its internal magnetic block, and a flipping component 400 for flipping the magnetic blocks on the upper support component 200 and the lower support component 300. The upper end 100 includes... The upper seat plate 110 has four side support rods 120 fixedly connected to its outer side wall at equal angles. The bottom end of the side support rods 120 is fixedly connected to a first support plate 130. The lower end 500 includes a lower seat plate 510. The top surfaces of the lower seat plate 510 are fixedly connected to two uprights 520. The top ends of the two uprights 520 are fixedly connected to an annular frame 550. The outer side wall of the annular frame 550 is fixedly connected to four second support plates 560 at equal angles. The four second support plates 560 correspond one-to-one with the four first support plates 130. There are four balloons 600, which are located between multiple sets of second support plates 560 and first support plates 130. The top ends of the two uprights 520 are fixedly connected to a sleeve frame 530. A magnet 540 is fixedly installed on the inner wall of the sleeve frame 530. The magnet 540 is located between two magnetic blocks.

[0038] Specifically, by setting up multiple balloons 600 distributed around the ring frame 550, the horizontal direction of the lower end 500 is buffered and limited. By setting up the upper support component 200 and the lower support component 300, the magnetic blocks on the upper support component 200 and the lower support component 300 simultaneously repel the magnet 540, thereby achieving non-contact support for the lower end 500 through the lower support component 300. This achieves a non-rigid connection between the upper end 100 and the lower end 500, reducing the vibration transmitted from the upper end 100 to the lower end 500, thereby reducing the shaking of the surveying instrument connected to the lower base plate 510 caused by the UAV.

[0039] Example 1

[0040] like Figures 5-7As shown, in this embodiment, the upper support assembly 200 includes a fixing frame 210. Fixing plates 140 are fixedly connected to both outer side walls of the fixing frame 210 and the upper base plate 110. Two transverse frames 230 are fixedly positioned on both sides of the fixing frame 210. Sleeve seats 220 are fixedly connected to both ends of the fixing frame 210. Shaft rods 251 are fixedly connected to both sides of one end of the outer sleeve 250. A gear 252 is fixedly sleeved at one end of the shaft rod 251. The inside of the gear 252 is fixedly installed with a magnetic block. The outer sleeve of the shaft rod 251... The side wall is slidably connected to the inner wall of the outer sleeve 250. There are two toothed plates 240, which are located above the transverse frame 230. The toothed plates 240 are fixedly connected to the fixed frame 210. The toothed plates 240 mesh with the adjacent gear 252. Two screws 700 are provided between the upper support assembly 200 and the lower support assembly 300. Both ends of the fixed frame 210 are fixedly connected to the socket seats 220. The screws 700 are slidably sleeved with the two adjacent socket seats 220. The top of the screws 700 is screwed with a nut 710.

[0041] In this embodiment, rotating the nut 710 adjusts the distance between the upper receiving component 200 and the lower receiving component 300, thereby adjusting the distance between the two magnetic blocks. Since the magnet 540 is located between the two magnetic blocks, adjusting the distance between the two magnetic blocks adjusts the vertical fluctuation range of the magnet 540.

[0042] like Figure 4 , 8 As shown, in this embodiment, the side walls of the second receiving plate 560 and the corresponding first receiving plate 130 that are close to each other are arc-shaped, and the side wall of the first receiving plate 130 is provided with a platform.

[0043] In practice, when the corresponding receiving plate 130 and receiving plate 2 560 move closer to each other, the balloon 600 is compressed, increasing its rebound force. This facilitates the return of the distance between the receiving plate 130 and the balloon 600 to their initial position. Due to the arc-shaped surface of the sidewall of the receiving plate 130, when the receiving plate 130 and receiving plate 2 560 are offset to the sides, the balloon 600 is further compressed. This causes the balloon 600 to rebound, pulling the receiving plate 130 and receiving plate 2 560 closer together. The lower end 500 is realigned, thereby restricting its rotation and movement in the horizontal direction. The balloon 600 is located between the first support plate 130 and the second support plate 560 and is not fixed to the first support plate 130 and the second support plate 560. When the first support plate 130 and the second support plate 560 are misaligned, the balloon 600 is rubbed. Compared with the existing method of fixing the rubber ball, the second support plate 560 has a larger range of motion, which is convenient to adapt to the up and down movement of the lower end 500.

[0044] Example 2

[0045] Based on Embodiment 1, in order to facilitate the flipping of the magnetic block in Embodiment 1, so as to make it easy to change the connection state between the upper end 100 and the lower end 500 as needed.

[0046] like Figures 4-7 As shown, in this embodiment, the flipping assembly 400 includes two mounting plates 410. The mounting plates 410 are fixedly connected to the top surface of the fixing frame 210. Fixing ears 420 are fixedly connected to both ends of the mounting plates 410. A lead screw 430 is rotatably connected between the top ends of the two fixing ears 420. A long groove 411 is formed on the top surface of the mounting plates 410. An internal threaded seat 440 is screwed onto the outer wall of the lead screw 430. A drive rod 450 is fixedly connected to the bottom end of the internal threaded seat 440. The top end of the drive rod 450 is slidably connected to the inner wall of the long groove 411. A sliding groove 451 is formed on the outer wall of the drive rod 450. The shaft 251 is connected to the adjacent side... The inner wall of the slide groove 451 is slidably connected. One end of the fixed frame 210 is fixed between the ends of the two lead screws 430 and a transmission box 460 is fixedly connected. The two lead screws 430 are synchronously driven through the transmission box 460. One end of the fixed frame 210 is fixedly connected to the drive motor 470. The output end of the drive motor 470 is connected to one end of the lead screw 430. The distance from the axis of the shaft 251 to the center of the side of the outer sleeve 250 is equal to one-quarter of the outer circumference of the gear 252. The receiving plate 130 and the upper seat plate 110 are perpendicular to each other. The distance from the transverse frame 230 to the bottom surface of the upper seat plate 110 is greater than the length of the outer sleeve 250.

[0047] In practice, initially, the two magnetic blocks repel the magnet 540. After the survey is completed, a signal controls the start of the drive motor 470, which drives a lead screw 430 to rotate. Through the transmission box 460, the two lead screws 430 rotate synchronously. When the lead screw 430 rotates, it drives the internal thread seat 440 to move along the mounting plate 410. The lead screw 430 drives the drive rod 450 to move, which in turn pushes the shaft 251. Through the meshing between the gear 252 and the gear plate 240, when the shaft 251 moves laterally, the gear 252 causes the outer sleeve 250 to flip. The distance from the axis of the shaft 251 to the center of the side of the outer sleeve 250... The distance is set to one-quarter of the outer circumference of gear 252. When gear 252 rotates half a turn, one end of outer component 250 moves to the original position of the other end, thereby causing outer component 250 to rotate half a turn in place. This causes the magnetic block and magnet 540 to change from a repulsive state to an attractive state, so that the two magnetic blocks and magnet 540 are attracted together. This allows the lower end 500 to switch to a rigid connection with the upper support component 200. This reduces the impact of the surveyor's swing on the drone's attitude when the drone is moved, making operation easier. When the drone is moved into place and ready for surveying, the lower end 500 and upper support component 200 switch back to a flexible connection.
