Description

Technical Field

[0001] This invention relates to the field of balancer technology, specifically to a magnetic balance connector, a drone, and a high-altitude spraying basket. Background Technology

[0002] High-altitude spray painting refers to coating operations performed on the surfaces of structures at heights, such as buildings, bridges, towers, ships, and wind turbine towers. Its core objective is to protect the substrate from environmental corrosion while enhancing its aesthetics. Traditionally, this involved manual climbing or using simple scaffolding and brush or roller coating, resulting in low efficiency and high risk. The mechanized stage introduced tools such as electric spray guns, lifting platforms, and suspended platforms to improve efficiency. The intelligent stage utilizes drone technology, employing AI path planning and visual recognition to achieve automated spray painting, reducing human risk. During spray painting, recoil force is generated. In the low-altitude economy, recoil-related issues have hindered the development of spray painting and fire protection technologies. To change this situation, relevant technological improvements are needed.

[0003] Specifically, for example, Chinese Patent 201610201459.7 discloses a high-altitude unmanned spray painting machine, particularly relating to a high-altitude unmanned spray painting machine. It includes a rectangular central plate, with two sets of four ailerons symmetrically arranged on both sides of the central plate. A propeller is installed at the end of each aileron. A butterfly-shaped anti-collision device is installed outside the four ailerons. The anti-collision device includes multiple hollow insulated carbon fiber tubes, connected in pairs by connecting plates to form an outer structure for protection. The carbon fiber tubes have a diameter of 40-50 cm, and the multiple tubes are interconnected, each containing an inflatable airbag. The distance between the propeller tips on the same side must not be less than 50 cm, and the distance between the propeller tips on both sides must not be less than 50 cm.

[0004] In the aforementioned existing technologies, during high-altitude spraying, whether using a suspended platform or a drone, recoil (force) is generated when the paint gun sprays. This recoil causes the drone's flight and the suspended platform to sway, resulting in deviations in the paint spraying trajectory and posing safety hazards. Therefore, a magnetic balance connector, a drone, and a high-altitude spraying platform are proposed to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to overcome the above-mentioned technical deficiencies and propose a magnetic balance connector, a drone, and a high-altitude spraying basket to solve the technical problem that the recoil of painting causes the drone's flight and the basket's suspension to sway, resulting in deviation of the paint spraying trajectory and posing safety hazards.

[0006] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution: In a first aspect, the present invention provides a magnetically balanced connector for mounting onto a carrier, comprising: Base; and A magnetic component includes a moving magnetic block, a fixed magnetic block, and a guiding mechanism. The fixed magnetic block is fixed on the base. The moving magnetic block and the fixed magnetic block are positioned opposite each other, and their opposing sides are magnetically repelled. The guiding mechanism is mounted on the base and has a movable end that is connected to the moving magnetic block and guides the moving magnetic block to slide linearly relative to the fixed magnetic block.

[0007] In some embodiments, the guiding mechanism includes a base rail and a base slider. The base rail is mounted on the base, and the base slider is slidably connected to the base rail and connected to the moving magnet.

[0008] In some embodiments, the transmission mechanism is disposed between the base and the guide mechanism, driving the movable end of the guide mechanism to move at a constant speed relative to the base.

[0009] In some embodiments, the transmission mechanism includes a drive gear and a drive rack, the drive rack being slidably connected to the guide mechanism to guide the drive rack to slide parallel to the sliding direction of the moving magnetic block, the drive gear meshing with the drive rack and being rotatably connected to the base, and the drive rack being connected to the movable end of the guide mechanism.

[0010] In some embodiments, the transmission mechanism further includes a guide frame and a reversing transmission assembly. The guide frame is mounted on the base and has a linearly sliding movable end. The reversing transmission assembly has a first end and a second end. The first end is connected to the movable end of the guide frame and is used to convert the linear movement of the movable end of the guide frame into a rotation of the second end perpendicular to the linear movement.

[0011] In some embodiments, the reversing transmission assembly includes a transmission rack, a transmission gear, a central shaft, a first bevel gear, a second bevel gear, and a transmission shaft. The transmission rack is mounted on the movable end of the guide frame and is parallel to the guiding direction of the guide frame. The transmission gear is coaxially connected to the central shaft and meshes with the transmission rack, converting the linear movement of the guide frame into the rotation of the central shaft. The central shaft is rotatably connected to the guide frame. The first bevel gear is coaxially connected to the central shaft. The transmission shaft is coaxially connected to the second bevel gear, and the second bevel gear meshes with the first bevel gear, converting the rotation of the central shaft into the rotation of the transmission shaft perpendicular to the central shaft.

[0012] In some embodiments, the second end of the reversing transmission assembly is connected to the drive gear, driving the drive gear to rotate. The distance the drive rack moves for one revolution of the drive gear is greater than the distance the transmission rack moves for one revolution of the transmission gear.

[0013] In some embodiments, the guide frame includes a guide rail and a guide slider. The guide rail is mounted on the base via a bracket and suspended above the guide mechanism. The guide slider is slidably connected to the guide rail.

[0014] Secondly, the present invention also provides a drone, including the magnetic balance connector described in any of the above.

[0015] Thirdly, the present invention also provides a high-altitude spraying basket, including the magnetic balance connector described in any one of the above.

[0016] Compared with the prior art, the magnetic balance connector provided by the present invention, by installing the base onto the corresponding carrier and using the magnetic components set on the base, uses a guide mechanism as the path guide between the fixed magnetic block and the moving magnetic block. When the spray paint recoil force is transmitted to the moving magnetic block, the moving magnetic block moves closer to the fixed magnetic block. Through the relative movement of the magnets, the magnetic field changes and generates a damping force, which consumes kinetic energy, forms a buffer, reduces the swaying amplitude of the carrier, and provides a dynamic balance between magnetic repulsion and recoil force, improving the stability of the spray painting.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0020] To address the technical problem that the recoil from painting causes drones to sway during flight or the suspension of the painting basket, leading to deviations in the paint spraying trajectory and posing safety hazards, this invention provides a magnetic balance connector, a drone, and a high-altitude painting basket. This effectively buffers the recoil generated by the paint gun during painting, improving the stability of the entire drone painting or unmanned painting process using a painting basket.

[0021] It should be noted that the magnetic balance connector described in this invention is used in, but not limited to, drones or unmanned painting in suspended baskets. For ease of explanation, this invention will only use the application of the magnetic balance connector in drones or unmanned painting in suspended baskets as an example. The principle of the magnetic balance connector in other types of equipment is essentially the same as that in drones or unmanned painting in suspended baskets, and will not be described in detail here.

[0022] Please see Figure 1 , Figure 1This is a schematic diagram of a single-layer structure of a magnetic balance connector in one embodiment of the present invention. It features a basic magnetic balance buffer structure. The magnetic balance connector includes a base 1 and a magnetic component 2, used for mounting on a carrier, which can be a drone, a basket, or other equipment requiring buffering. In this embodiment, it is mainly mounted on a drone or basket for buffering the recoil of a paint spray gun. The magnetic component 2 includes a moving magnetic block 21, a fixed magnetic block 22, and a guiding mechanism 23. The fixed magnetic block 22 is fixed to the base 1. The moving magnetic block 21 and the fixed magnetic block 22 are positioned opposite each other, with their opposing sides magnetically repelling each other. When the moving magnetic block 21 moves towards the fixed magnetic block 22, the magnetic repulsion provides magnetic buffering. The relative movement of the magnets and the change in the magnetic field generate damping force, consuming kinetic energy. The guiding mechanism 23 is mounted on the base 1 and has a movable end connected to the moving magnetic block 21, guiding the moving magnetic block 21 to slide linearly relative to the fixed magnetic block 22, thus providing a stable path for the moving magnetic block 21 to move relative to the fixed magnetic block 22. The paint gun is fixedly mounted on the movable end of the moving magnetic block 21 or the guide mechanism 23, and the spraying direction is parallel to the guiding direction of the guide mechanism 23. When the recoil force of the paint spraying is generated, as the moving magnetic block 21 moves towards the fixed magnetic block 22, the magnetic repulsion provides magnetic buffering. The relative movement of the magnets and the change in the magnetic field generate damping force, which consumes kinetic energy and forms a buffer, reducing the shaking amplitude. During continuous spraying, after the buffering, the magnetic repulsion and recoil force form a dynamic balance, thereby maintaining the stability of the spraying and reducing the error of the paint trajectory. The magnetic buffering has the characteristic of being generated and disappearing simultaneously, and does not generate excess energy consumption when not in use. Furthermore, it is sufficiently energy-saving and environmentally friendly.

[0023] Optionally in this embodiment, a damping element 24 may be provided between the moving magnetic block 21 and the fixed magnetic block 22. The function of the damping element 24 is to provide motion resistance, reduce the vibration energy of the structure or object, thereby reducing the vibration amplitude, reducing the impact force, and improving the stability and safety of the system.

[0024] Optionally in this embodiment, bolts are installed on the base 1 of the magnetic balance connector for mounting to a drone or a high-altitude suspended platform.

[0025] Understandably, in order to achieve dynamic control or high-precision buffering, damping control algorithms, such as hysteresis compensation, or physical damping elements, such as springs or magnetorheological fluids, can be used to stabilize energy dissipation.

[0026] In one embodiment, please refer to Figure 1To provide basic guiding functionality in the magnetic buffer, the guiding mechanism 23 includes a base rail 231 and a base slider 232. The base rail 231 is mounted on the base 1, and the base slider 232 is slidably connected to the base rail 231 and connected to the moving magnetic block 21. The base rail 231 consists of two parallel single rails, and the base slider 232 spans across the two single rails. The moving magnetic block 21 is fixedly connected to the base slider 232, and the base rail 231 provides guidance, guiding the base slider 232 and the moving magnetic block 21 to move along the guiding direction.

[0027] Understandably, the basic guide rail 231 can also be a single rail, which can also achieve the guiding effect.

[0028] In one embodiment, please refer to Figure 1 To provide a uniform speed effect during the movement of the moving magnetic block 21, a transmission mechanism 3 is also included. The transmission mechanism 3 includes a drive gear 31 and a drive rack 32. The drive rack 32 is slidably connected to the guide mechanism 23, guiding the drive rack 32 to slide parallel to the sliding direction of the moving magnetic block 21. The drive gear 31 meshes with the drive rack 32 and is rotatably connected to the base 1. The drive rack 32 is connected to the movable end of the guide mechanism 23. Through the meshing of the drive gear 31 and the drive rack 32, a uniform speed effect is formed throughout the entire buffer stroke, making the entire stroke more stable.

[0029] Understandably, in this embodiment, the drive rack 32 is fixedly connected to the base slider 232 or the moving magnetic block 21. As the moving magnetic block 21 moves, it drives the drive rack 32 to move relative to the drive gear 31. Alternatively, the drive gear 31 can be rotatably connected to the base slider 232, and the drive rack 32 can be fixed to the base guide rail 231 to achieve the same effect. However, this layout is not convenient for double-layer structures and is only suitable for single-layer structures.

[0030] It should be noted that the transmission mechanism 3 can also adopt mechanical structures with uniform speed, such as ball screws.

[0031] In one embodiment, please refer to Figure 2 and Figure 3To accommodate the limited vertical space at the top of the drone and provide sufficient buffer travel for a lateral layout, the transmission mechanism 3 further includes a guide frame 33 and a reversing transmission assembly 34. The guide frame 33 is mounted on the base 1 and supported above the guide mechanism 23 by a bracket, and has a linearly sliding movable end to guide the buffer sliding direction of the paint gun, i.e., the paint gun is mounted on the movable end of the guide frame 33. The reversing transmission assembly 34 has a first end and a second end. The first end is connected to the movable end of the guide frame 33 and is used to convert the linear movement of the movable end of the guide frame 33 into a rotation of the second end perpendicular to the linear movement. The second end is connected to the drive gear 31 of the transmission mechanism 3, so that when the movable end slides, it drives the second end to rotate, i.e., drives the drive gear 31 to rotate. Under the meshing transmission of the drive gear 31 and the drive rack 32, the drive rack 32 is driven to move, which in turn drives the moving magnet 21 to move.

[0032] The sliding direction of the guide frame 33 is at an angle of 90 degrees to the sliding direction of the guide mechanism 23, which allows the magnetic buffer part to be arranged laterally. Even when the longitudinal dimension is insufficient, it can be effectively installed on the drone.

[0033] It is understandable that a 90-degree angle is merely a preferred installation method. Given other size limitations, other angles can achieve the same effect, so no single limitation is made here.

[0034] Specifically, for the specific reversing effect, please refer to [link / reference]. Figure 2 and Figure 3 The reversing transmission assembly 34 includes a transmission rack 341, a transmission gear 342, a central shaft 343, a first bevel gear 344, a second bevel gear 345, and a transmission shaft 346. The transmission rack 341 is mounted on the movable end of the guide frame 33 and is parallel to the guiding direction of the guide frame 33. The transmission gear 342 is coaxially connected to the central shaft 343 and meshes with the transmission rack 341, converting the linear movement of the guide frame 33 into the rotation of the central shaft 343. The movement of the movable end of the guide frame 33 drives the transmission rack 341 to move, drives the transmission gear 342 to rotate, and then drives the central shaft 343 to rotate.

[0035] Understandably, when the paint gun is mounted on the movable end of the guide frame 33, the paint spraying generates recoil, causing the movable end to move in the opposite direction. At this time, the transmission rack 341 is displaced, driving the transmission gear 342 to rotate, which in turn drives the central shaft 343 to rotate for transmission.

[0036] Furthermore, in order to transmit the transmission of the central shaft 343 to the magnetic component below, the central shaft 343 is rotatably connected to the guide frame 33, the first bevel gear 344 is coaxially connected to the central shaft 343, the transmission shaft 346 is coaxially connected to the second bevel gear 345, and the second bevel gear 345 meshes with the first bevel gear 344, converting the rotation of the central shaft 343 into the rotation of the transmission shaft 346 perpendicular to the central shaft 343. The transmission shaft 346 is coaxially connected to the drive gear 31. Through the rotation of the central shaft 343, the first bevel gear 344 is driven to rotate, the first bevel gear 344 drives the second bevel gear 345 to rotate, the second bevel gear 345 drives the transmission shaft 346 to rotate, and then drives the drive gear 31 to rotate. Under the meshing transmission of the drive gear 31 and the drive rack 32, the drive rack 32 is driven to move, and then the moving magnetic block 21 is driven to move, forming a buffer in the magnetic component.

[0037] Furthermore, to further reduce the spray gun stroke fluctuations caused by buffering, please refer to [link / reference needed]. Figure 2 and Figure 3 The second end of the reversing transmission assembly 34 is connected to the drive gear 31, driving the drive gear 31 to rotate. The movement distance of the drive rack 32 corresponding to one rotation of the drive gear 31 is greater than the movement distance of the transmission rack 341 corresponding to one rotation of the transmission gear 342, thereby shortening the displacement stroke formed on the guide frame 33. Through the transmission ratio, a sufficient buffer stroke is formed on the magnetic component 2, and the movable end on the guide frame 33 only needs to form a smaller displacement than that formed by the magnetic component 2 to achieve a buffering and stabilizing effect. This can further reduce the shaking amplitude generated during paint spraying.

[0038] Furthermore, to provide reversing transmission without interfering with the displacement of each component in the double-layer structure, the drive rack 32 is mounted on both sides of the guide rail, with grooves for sliding connection between the drive rack 32 and the guide rail. The tooth surface of the drive rack 32 faces away from the guide rail. Correspondingly, the drive gear 31 is mounted on both sides of the guide rail and meshes with the tooth surface of the drive rack 32. The drive gear 31 is positioned so as not to interfere with the displacement of the movable end of the upper guide frame 33. The external placement of the drive gear 31 outside the guide rail also avoids interference with the movable end of the guide mechanism 23.

[0039] In another embodiment, when sufficient installation space is available, to reduce the undulation of the paint gun caused by buffering, the sliding direction of the guide frame 33 is parallel to the sliding direction of the guide mechanism 23. Furthermore, the second end of the reversing transmission assembly 34 is connected to the drive gear 31, driving the drive gear 31 to rotate. The distance the drive rack 32 moves for one revolution of the drive gear 31 is greater than the distance the transmission rack 341 moves for one revolution of the transmission gear 342. Thus, in the longitudinal space, the double-layer structure reduces the displacement stroke of the upper paint gun while providing sufficient magnetic buffering stroke for the lower layer.

[0040] Understandably, adjusting the diameter of the transmission gear 342, the transmission ratio between the first bevel gear 344 and the second bevel gear 345, and the diameter of the drive gear 31 can achieve the desired difference between the displacement distance of the drive rack 32 and the displacement of the transmission rack 341 driven by the movable end of the guide frame 33. For example, when the first bevel gear 344 rotates one revolution, the second bevel gear 345 rotates two revolutions, the diameter of the drive gear 31 is the same as the diameter of the transmission gear 342, and the distance the drive rack moves in one revolution is the same. In this case, the drive rack 32 can be moved to a displacement twice that of the transmission rack 341. As another example, when the first bevel gear 344 rotates one revolution, the second bevel gear 345 also rotates one revolution, but the diameter of the drive gear 31 is twice that of the transmission gear 342. That is, the distance the drive rack moves in one revolution of the drive gear 31 is twice the distance the drive rack moves in one revolution, and the drive rack 32 can also be moved to a displacement twice that of the transmission rack 341. By changing these conditions, the desired displacement ratio can be achieved.

[0041] In one embodiment, please refer to Figure 2 and Figure 3 In order to guide the displacement of the guide frame 33 and connect it to the base 1, the guide frame 33 includes a guide rail 331 and a guide slider 332. The guide rail 331 is mounted on the base 1 by a bracket and suspended above the guide mechanism 23. The guide slider 332 is slidably connected to the guide rail 331, and the guide is performed by the relative sliding between the guide slider 332 and the guide rail 331.

[0042] Understandably, the guide frame 33 can also be composed of two parallel single rails, with the guide slider 332 spanning across the two single rails. The guide frame 33 provides guidance, guiding the guide slider 332 to move along the guiding direction. The guide frame 33 can also use a single track, which can also achieve the guiding effect.

[0043] To better understand this invention, the following is combined with... Figures 1 to 5The technical solution of the present invention is described in detail as follows: In the single-layer structure, the moving magnetic block 21 is directly installed and connected to the paint gun, and the guiding direction is parallel to the paint spraying axis of the paint gun. When the paint spraying generates recoil force, it acts directly on the moving magnetic block 21 and slides along the base guide rail 231 of the guide mechanism 23 towards the fixed magnetic block 22, forming a magnetic buffer. In the double-layer structure, in order to reduce the displacement of the paint gun in the buffer, the guide rail 331 of the guide frame 33 is arranged parallel to the base guide rail 231 and stacked on top of the guide mechanism 23. Under the transmission of the reversing transmission assembly 34, the moving distance of the paint gun is less than the buffer stroke of the moving magnetic block, thereby achieving the purpose of reducing the buffer displacement of the paint gun. Specifically, in the first When bevel gear 344 rotates once, second bevel gear 345 also rotates once. The diameter of drive gear 31 is twice that of transmission gear 342. That is, when drive gear 31 rotates once, the distance the drive rack moves is twice the distance the transmission gear 342 moves. It can also drive drive rack 32 to move at a displacement twice that of transmission rack 341. In the double-layer structure, in order to arrange the magnetic component 2 laterally, the guide rail 331 of guide frame 33 is set at a 90-degree angle to the base guide rail 231. At this time, under the transmission of reversing transmission component 34, the longitudinal linear movement can be converted into the lateral linear movement of moving magnetic block 21, thereby satisfying the situation where the longitudinal dimension is insufficient and the magnetic component 2 needs to be arranged laterally.

[0044] The present invention also provides a drone, including the magnetic balance connector described in any of the above embodiments. The magnetic balance connector is installed at the top or bottom center of the drone and a paint gun is installed through the magnetic balance connector. Based on this, magnetic buffering is provided when the paint gun is spraying paint, which can effectively reduce the shaking of the drone during painting and improve stability and safety.

[0045] The present invention also provides a high-altitude spraying basket, including the magnetic balance connector described in any of the above embodiments. The basket can move up and down and left and right on the building. Furthermore, the basket is provided with left and right slide rails for installing the magnetic balance connector. The spray gun is then installed on the magnetic balance connector. The magnetic balance connector can form a recoil buffer for spraying, reducing the swaying of the basket and having the effects of vibration reduction and collision prevention.

[0046] The specific embodiments of the present invention described above do not constitute a limitation on the scope of protection of the present invention. Any other corresponding changes and modifications made in accordance with the technical concept of the present invention should be included within the scope of protection of the claims of the present invention.
