Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicles, and in particular to a wireless charging bracket for landing an electric power inspection unmanned aerial vehicle. Background Art

[0002] In recent years, drones have played an important role in both civil and military fields. Among them, multi-rotor drones have the advantages of controllable speed, vertical take-off and landing, and precise hovering, and have played an important role in agricultural and forestry plant protection, transportation and distribution, reconnaissance and surveillance, etc. Although with the continuous improvement of the performance of multi-rotor drones, they have shown broad application prospects in many fields, but their endurance and power supply problems have not been effectively improved. The limited endurance time causes multi-rotor drones to only perform short-distance and small-scale operations, which seriously limits the application of multi-rotor drones.

[0003] At present, there are three main traditional solutions to the problem of drone endurance: (1) equipping drones with solar cells to achieve energy self-sustaining; (2) using the robot arm of the drone nest to replace the fully charged battery for the drone. This has the advantage of high operating efficiency, but it requires the modification of the drone and requires sophisticated mechanical and control devices; (3) using a wireless charging platform for wireless charging.

[0004] Among them, the wireless charging technology of drones uses the principle of electromagnetic induction to achieve the transmission of electrical energy through the change of magnetic field between the transmitting coil and the receiving coil. When the transmitting coil is energized, a changing magnetic field is generated, which generates an induced current in the receiving coil, thereby charging the drone battery.

[0005] As a charging device for drones when they land, the wireless charging stand is prone to accumulate dust, dirt and other impurities during use. These impurities may adhere to the wireless charging coil or metal contacts, affecting the charging efficiency. In addition, the wireless charging coil of the wireless charging stand is directly exposed to the outside, increasing the risk of electric shock or short circuit. Summary of the invention

[0006] The purpose of the present invention is to solve the problem that the charging seat of the existing wireless charging bracket is prone to accumulate dust, dirt and other impurities during use, and these impurities may adhere to the wireless charging coil or metal contacts, affecting the charging efficiency, and to propose a wireless charging bracket for landing a power inspection drone.

[0007] In order to achieve the above-mentioned purpose, the present invention adopts the following technology: a wireless charging bracket for landing a power inspection drone, comprising a wireless charging seat arranged on a base, a support component capable of shock absorption is arranged at the bottom corner position of the base, a shielding and protection mechanism for safety protection and surface cleaning of the wireless charging seat is arranged on the base, and at least two cooling fans connected to the inside of the base are arranged on the bottom plate of the base;

[0008] The shielding and protection mechanism includes a shielding cover plate for covering and protecting the wireless charging seat, which is arranged on the base and can be moved along the length direction of the base through a slide rail. The shielding cover plate is provided with a cleaning component for cleaning impurities and dust on the surface of the wireless charging seat, and the base is provided with a limiting component for positioning and fixing the shielding cover plate.

[0009] As a further description of the above technical solution: the cleaning component includes a mounting base that is detachably mounted on the shielding cover through a mounting opening, and the mounting base is provided with cleaning cotton that contacts the top of the wireless charging base.

[0010] As a further description of the above technical solution: both ends of the mounting seat are provided with plug plates that can move along the length direction thereof through the mounting grooves, and an ejection spring is provided between the plug plates and the mounting grooves;

[0011] The shielding cover is provided with clamping plates located at both sides of the mounting seat, and the clamping plates are provided with plug holes matched with the plug plates.

[0012] As a further description of the above technical solution: a notch communicating with the mounting groove is provided on the mounting seat, and a pull plate penetrating the notch is provided on the plug plate.

[0013] As a further description of the above technical solution: the limit assembly includes a pull rod arranged at one end of the base through a mounting block, a limit plate is arranged on the pull rod, and a return spring is sleeved at a position between the limit plate and the mounting block on the pull rod;

[0014] The bottom of the shielding cover plate is provided with a limiting hole matched with the top of the pull rod.

[0015] As a further description of the above technical solution: the shielding and protection mechanism also includes a dustproof component arranged in the vent of the shielding cover;

[0016] The dustproof assembly includes a dustproof net arranged inside the vent through a fixing block.

[0017] As a further description of the above technical solution: a positioning rod penetrating the dustproof net is arranged on the fixing block, and a locking nut abutting against the outer surface of the dustproof net is arranged on the positioning rod through a threaded end.

[0019] As a further description of the above technical solution: a shock-absorbing spring is sleeved on the connecting rod at a position between the supporting leg and the connecting sleeve, and a buffer pad is filled between one end of the connecting rod located inside the connecting sleeve and the connecting sleeve.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0021] The shielding cover can slide horizontally to effectively shield and protect the charging seat. During the power inspection of the drone, the wireless charging seat can be shielded to prevent foreign objects from falling on the charging seat and damaging the charging seat coil.

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Reference Figure 1-Figure 10 The wireless charging bracket for landing a power inspection drone provided in this embodiment includes a wireless charging seat 2 arranged on a base 1, a support component 3 capable of shock absorption is arranged at the bottom corner of the base 1, a shielding protection mechanism 4 for safety protection and surface cleaning of the wireless charging seat 2 is arranged on the base 1, and at least two cooling fans 5 connected to the inside of the base 1 are arranged on the bottom plate of the base 1;

[0037] The shielding and protection mechanism 4 includes a shielding cover 41 which is arranged on the base 1 and can be moved along the length direction of the base 1 through a slide rail 11 for covering and protecting the wireless charging seat 2. The shielding cover 41 is provided with a cleaning component 42 for cleaning impurities and dust on the surface of the wireless charging seat 2, and the base 1 is provided with a limiting component 43 for positioning and fixing the shielding cover 41.

[0038] In the present invention, the wireless charging bracket is placed and fixed by the supporting component 3 at the bottom of the base 1. When the UAV is inspecting the power, the shielding cover 41 is closed to shield and protect the wireless charging seat 2 in the base 1 to prevent foreign objects from entering the base 1, and to prevent dust and moisture from falling on the wireless charging seat 2 to cause damage to the coil. When the UAV needs to be charged, the limit component 43 is opened to slide the shielding cover 41 open, so that the wireless charging seat 2 is exposed. During the opening of the shielding cover 41, the cleaning component 42 on the shielding cover 41 can clean the surface of the wireless charging seat 2 to prevent residual dust and moisture, thereby ensuring good contact between the UAV and the charging seat, and improving the charging efficiency. After the shielding cover 41 is opened, the UAV lands on the wireless charging seat 2, and wireless charging is performed through the transmitting coil on the wireless charging seat 2 and the receiving coil on the UAV. After charging is completed, the UAV continues to perform power inspection. During the charging process, the cooling fan 5 at the bottom of the base 1 can dissipate the heat of the wireless charging seat 2 in the base 1, and then the shielding cover 41 can be closed;

[0039] It should be noted that the cleaning component 42 includes a mounting base 421 that is detachably mounted on the shielding cover 41 through a mounting port, and a cleaning cotton 422 that contacts the top of the wireless charging base 2 is provided on the mounting base 421. When the shielding cover 41 moves, the cleaning cotton 422 on the mounting base 421 slides on the surface of the wireless charging base 2, thereby cleaning the dust on the surface of the wireless charging base 2 through the cleaning cotton 422 to avoid a reduction in charging efficiency due to obstruction by dust.

[0040] Specifically, Figure 2 , Figure 5-Figure 7 As shown, both ends of the mounting seat 421 are provided with plug plates 424 that can move along the length direction thereof through the mounting grooves 423, and ejection springs 425 are provided between the plug plates 424 and the mounting grooves 423. The shielding cover 41 is provided with clamping plates 411 located on both sides of the mounting seat 421, and the clamping plates 411 are provided with jacks that match the plug plates 424. The mounting seat 421 is provided with a slot 426 that is connected to the mounting groove 423, and the plug plates 424 are provided with a pull plate 427 that passes through the slot 426.

[0041] Among them, in order to ensure that the cleaning cotton 422 of the cleaning component 42 can always effectively clean dust and moisture, it is necessary to clean and replace the cleaning component 42 regularly. When the cleaning component 42 needs to be disassembled for cleaning and replacement, the pull plate 427 is used to pull the plug plate 424 so that the plug plate 424 compresses the ejection spring 425 and shrinks in the mounting groove 423. At this time, the plug plate 424 is separated from the socket of the clamping plate 411, and then the mounting seat 421 together with the cleaning cotton 422 can be pulled out from the mounting opening of the shielding cover 41 to achieve the disassembly work. After the cleaning cotton 422 is cleaned or replaced, the pull plate 427 is used again to shrink the plug plate 424 in the mounting groove 423. After the mounting seat 421 is stuck in the mounting opening of the shielding cover 41, the pull plate 427 is released. At this time, the plug plate 424 pops out and is stuck in the socket of the clamping plate 411 under the action of the ejection spring 425, so that the cleaning component 42 is fixed on the shielding cover 41.

[0042] Specifically, Figure 4 , Figure 5 and Figure 8 As shown, the limiting assembly 43 includes a pull rod 432 arranged at one end of the base 1 through a mounting block 431, a limiting plate 433 is arranged on the pull rod 432, and a return spring 434 is sleeved on the pull rod 432 at a position between the limiting plate 433 and the mounting block 431, and a limiting hole matching the top of the pull rod 432 is opened at the bottom of the shielding cover 41.

[0043] Among them, there are two pairs of limiting holes at the bottom of the shielding cover 41, and the two pairs of limiting holes are respectively close to the two ends of the shielding cover 41. When the shielding cover 41 needs to be opened for charging the drone, the pull rod 432 is pulled downward to make the limiting plate 433 on the pull rod 432 compress the reset spring 434. At this time, the top of the pull rod 432 is separated from the limiting holes at the bottom of one end of the shielding cover 41 away from each other, and then the shielding cover 41 is moved by the slide rail 11. When the shielding cover 41 is opened, it is slowly Slowly release the pull rod 432. Under the reset action of the reset spring 434, the pull rod 432 is inserted into the limiting hole at the bottom of the end where the shielding cover 41 is close to each other, so that the shielding cover 41 remains in an open state. After charging is completed, repeat the operation of opening the pull rod 432. After the shielding cover 41 is closed, release the pull rod 432 again, and then the top of the pull rod 432 is inserted into the limiting hole at the bottom of the end where the shielding cover 41 is away from each other, so as to achieve the closure of the shielding cover 41.

[0044] Specifically, Figure 5 and Fig. 9As shown, the shielding protection mechanism 4 also includes a dustproof component 45 arranged in the ventilation port 44 of the shielding cover 41, and the dustproof component 45 includes a dustproof net 453 arranged inside the ventilation port 44 through a fixing block 451, and a positioning rod 452 passing through the dustproof net 453 is arranged on the fixing block 451, and a locking nut 455 abutting against the outer surface of the dustproof net 453 is arranged on the positioning rod 452 through a threaded end 454.

[0045] The vents 44 on the shielding cover 41 are used for ventilation and heat dissipation. After the wireless charging seat 2 on the base 1 is charged, closing the shielding cover 41 will not affect the heat dissipation of the wireless charging seat 2, and the dustproof net 453 on the vents 44 can prevent impurities such as dust and particles from entering the base 1 and falling on the wireless charging seat 2, ensuring that the vents 44 are ventilated and heat dissipated without dust gathering on the wireless charging seat 2;

[0046] The dustproof net 453 is resting on the fixed block 451 through the positioning rod 452. When the dustproof net 453 needs to be disassembled for cleaning and maintenance, the locking nut 455 on the threaded end 454 of the positioning rod 452 is unscrewed, and then the dustproof net 453 can be removed from the positioning rod 452, thereby realizing the disassembly of the dustproof net 453, which is simple and convenient, and facilitates the cleaning of the dustproof net 453.

[0047] Specifically, Figure 1 and Fig.10 As shown, the support assembly 3 includes a support leg 31 arranged at the bottom of the base 1, a connecting sleeve 33 is arranged at the bottom of the support leg 31 through a connecting rod 32, and a foot pad 34 is arranged at the bottom of the connecting sleeve 33, a shock-absorbing spring 35 is sleeved on the connecting rod 32 at a position between the support leg 31 and the connecting sleeve 33, and a buffer pad 36 is filled between one end of the connecting rod 32 located inside the connecting sleeve 33 and the connecting sleeve 33.

[0048] Among them, the support leg 31 is fixed to the base 1 through the mounting plate on the top. When the wireless charging bracket is in use, the foot pad 34 at the bottom of the connecting sleeve 33 plays an anti-slip role to ensure the stability of the charging bracket. The connecting rod 32 can realize short-range telescopic movement on the connecting sleeve 33, and cooperate with the shock-absorbing spring 35 and the buffer pad 36 to make the support component 3 have excellent shock-absorbing and buffering effects, thereby effectively absorbing and dispersing the impact force when the drone lands for charging, and can also ensure that the drone remains stable during the charging process, avoiding charging interruptions caused by vibration or impact, thereby improving the charging efficiency.

[0049] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
