[0030] like Figure 1-8 As shown, the present invention provides a wireless charging device 100 for a drone, including a base 1, on which two strip grooves 2 are provided, the two strip grooves 2 are parallel and spaced apart, and the two strip grooves 2 are respectively used to accommodate two support rods 200 for clamping the drone, and at least one electromagnet 3 is installed in each strip groove 2, each electromagnet 3 is electrically connected to a power transmission device (not shown in the figure), and the electromagnet 3 is used to absorb or release the support rod 200 in the corresponding strip groove 2.

[0031] In the above technical solution, the present application does not limit the specific structure of the base 1, nor does it limit the number of the electromagnets 3, which can be 1, 2, 3, etc., as long as they can play the role of fixing the support rod 200. In some embodiments, the number of the at least one electromagnet 3 is two, and the two electromagnets 3 can stably adsorb the support rod 200. When the number of electromagnets 3 is too large, the manufacturing cost is high and it is not cost-effective. In some embodiments, the number of the at least one electromagnet 3 is two, and the two electromagnets 3 are respectively installed at the two ends of the strip groove 2, which can more stably fix the support rod 200. The drone includes a landing gear, which includes two support rods 200 arranged parallel to each other, and both ends of each support rod 200 are connected to the drone through a connecting rod. When the drone lands, the support rod 200 is placed on the landing platform to support the drone, wherein the support rod 200 is made of stainless steel.

[0032] In the present invention, the two strip grooves 2 are arranged on the base 1 for accommodating the two support rods 200 for clamping the drone, and at least one electromagnet 3 is placed in each strip groove 2. When each support rod 200 is placed in the corresponding strip groove 2, the power transmission device energizes each electromagnet 3, so that the electromagnet 3 has magnetic force and can absorb the support rod 200, thereby stabilizing the support rod 200. When the electromagnet 3 is powered off, the suction force of the electromagnet 3 on the support rod 200 disappears. The present invention stabilizes the support rod 200 by arranging the strip grooves 2 and arranging the electromagnet 3 in the strip grooves 2, thereby stabilizing the drone, thereby solving the problem in the prior art that the drone cannot be stably parked on the base 1 due to wind force and its own movement, thereby affecting its charging process.

[0033] Furthermore, it also includes a telescopic mechanism 4 and two groups of locking pieces 5; the telescopic mechanism 4 is arranged between the two strip grooves 2; the two groups of locking pieces 5 are arranged one-to-one with the two strip grooves 2, and each locking piece 5 includes two locking strips 51, the two locking strips 51 are arranged at intervals along the height direction of the strip groove 2, and each locking strip 51 is arranged along the width direction of the strip groove 2, one end of the locking strip 51 is connected to the telescopic mechanism 4, and the telescopic mechanism 4 controls the locking strip 51 to enter or leave the strip groove 2, and the two locking strips are used to clamp and fix the corresponding support rods 200 along the height direction of the strip groove.

[0034] In the above technical solution, exemplarily, with the vertical ground as the vertical direction, when the base 1 is placed on the ground, each locking strip 51 is horizontally located in the strip groove 2 and is placed along the width direction of the strip groove 2. There is a height difference between the two locking strips 51 in the vertical direction. When the support rod 200 is located in the strip groove 2, the two locking strips 51 can be clamped on the upper and lower sides of the support rod 200. One end of each locking strip 51 is connected to the telescopic mechanism 4. The telescopic mechanism 4 can control the locking strip 51 to enter or move away from the strip groove 2. When the support rod 200 is located in the strip groove 2, the two locking strips 51 can be clamped on the upper and lower sides of the support rod 200. When located inside the strip groove 2, the telescopic mechanism 4 controls the locking strip 51 to enter the inside of the strip groove 2 to clamp the support rod 200. In some embodiments, in order to further stabilize the support rod 200, the two locking strips 51 can be arranged to be spaced apart along the length direction of the strip groove 2. When the support rod 200 is about to leave the strip groove 2, the telescopic mechanism 4 controls the locking strip 51 to leave the strip groove 2. The present application does not limit the specific structure of the telescopic mechanism 4, as long as it can control the locking strip 51 to enter or move away from the strip groove 2.

[0035] The present invention further provides a locking piece 5 in the strip groove 2. When the support rod 200 enters the strip groove 2, the two locking strips 51 enter the strip groove 2 under the control of the telescopic mechanism 4 and are clamped on the outside of the support rod 200. The support rod 200 is further fixed by the clamping force, thereby further stabilizing the drone.

[0036] In some embodiments, a cavity (not shown in the figure) is provided inside the base 1, and the cavity is located between the two strip grooves 2 and is connected to the two strip grooves 2. The telescopic mechanism 4 is located in the cavity. The purpose of setting the cavity is to hide the telescopic mechanism 4 inside the base 1 to prevent the telescopic mechanism 4 from being exposed to the outside, thereby protecting the telescopic mechanism 4.

[0037] It can be understood that two limiting grooves 6 are provided in each strip groove 2, and the two limiting grooves 6 are arranged one by one with the two locking strips 51. Each limiting groove 6 is located on the side wall of the strip groove 2 away from the telescopic mechanism 4. When the locking strip 51 is used to clamp and fix the support rod 200, the other end of the locking strip 51 is located in the corresponding limiting groove 6 to limit the locking strip 51. The limiting groove 6 is as shown in FIG. Figure 6 As shown, it plays the role of limiting the locking strip 51 . The present application does not limit the specific shape of the limiting groove 6 , as long as it is compatible with the locking strip 51 .

[0038] In the new technical solution, if Figure 7The telescopic mechanism 4 shown in the figure includes two telescopic parts 41, each telescopic part 41 includes a gear 411 and two racks 412; the gear 411 is arranged in a cavity and is connected to a rotating motor (not shown in the figure); the two racks 412 are arranged opposite to each other and are clamped on the outside of the gear 411, each rack 412 is slidably engaged with the base 1, and the gear 411 rotates to drive the two racks 412 to move; the two locking bars 51 in each group of locking parts 5 are arranged in a one-to-one correspondence with the two telescopic parts 41, and each locking bar 51 is connected to the rack 412 in the corresponding telescopic part 41, and the two racks 412 connected by the two locking bars 51 have the same movement direction. The same movement direction here means that when the support rod 200 is in the When in the strip groove 2, driven by the gear 411, the two racks 412 can drive the two locking bars 51 to move into the strip groove 2. The present application does not limit the specific connection method between the locking bar 51 and the rack 412, and they can be connected by welding, bonding, etc. At the same time, other structures in the present application, if not specifically stated to require a fixed connection, can also be connected by welding, bonding, etc., wherein the specific structure of the sliding engagement between each rack 412 and the base 1 is not limited. For example, a slide groove is provided on the base 1, and a slider is provided on the side of the rack 312 away from the gear 411. The slider is engaged with the slide groove to achieve the sliding engagement between the rack 412 and the base 1.

[0039] Furthermore, it also includes a transmitting device, which is installed in the cavity of the base 1. The transmitting device may include a charging coil. The transmitting device is installed in the cavity of the base 1, which plays a protective role on the transmitting device.

[0040] Furthermore, it also includes an ultrasonic detection device 7 for detecting whether the two support rods 200 of the drone are located in the two strip grooves 2. When the ultrasonic detection device 7 detects that the support rods 200 of the drone have reached the specified position, each electromagnet 3 is energized, and the locking member 5 locks the support rods 200 to maintain the stability of the drone, so as to solve the problem in the prior art that the drone cannot be stably parked on the base 1 due to wind force and its own movement, thereby affecting its charging process.

[0041] Detailed usage process: When the drone needs to be charged, first, the two unconnected support rods 200 are parked inside the two strip grooves 2 respectively. At the same time, when the ultrasonic detection device 7 detects that the support rods 200 have reached the specified position, all the electromagnets 3 are energized to absorb the support rods 200, and the telescopic mechanism 4 controls the locking pieces 5 to enter the strip grooves 2 and are clamped on both sides of the support rods 200. When each locking strip 51 moves into place, the other end of each locking strip 51 is located in the limiting groove 6. After the drone is stabilized, the transmitting device starts to generate energy to the drone, and the receiving device on the drone receives the energy. When the drone needs to leave after charging is completed, the telescopic mechanism 4 controls the locking pieces 5 to leave the strip grooves 2, and the electromagnets 3 are all powered off, and the drone can leave at this time.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
