DETAILED DESCRIPTION

[0020] The following will refer to the attached Figures 1 to 10 The embodiments of the present invention are described in detail. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0021] Embodiment 1

[0022] A UAV charging platform structure with foreign body removal, as shown in the attached Figure 1 As shown, it includes a charging pad body 2 and support plates 3 on the left and right sides of the bottom of the charging pad body 2. The charging pad body 2 is supported by the support plates 3 and can remain flat for shutdown and wireless charging. A push rod 1 is provided on the charging pad body 2 for sliding along the left and right directions. Specifically, a sliding mechanism can be set between the front and rear sides of the charging pad body 2 and the push rod 1. In this embodiment, two push rods 1 are provided, and a control mechanism for controlling the sliding of the two push rods 1 is provided at the front end of the push rod 1.

[0023] As attached Figure 2 , Figure 3 , Figure 5 , Figure 8As shown, the control mechanism includes a mounting plate 5, on which a first slide groove 25 and a second slide groove 12 are provided in a vertical direction in the up-down direction, a first slide groove 25 is provided with a first slider 24, and a second slide groove 12 is provided with a second slider 10, and a transmission rod A6 is rotatably connected to the first slider 24, and the rotation axis is in the front-to-back direction. In this embodiment, two transmission rods A6 are provided to form an "X" structure, and one end of the top of the transmission rod A6 is rotatably connected to the front end of the corresponding push rod 1, and the rotation axis is in the front-to-back direction. A lifting frame 7 is provided at one end of the bottom of the two transmission rods A6, and a third slide groove is provided on the lifting frame 7 along the left-right direction, and two third sliders 8 are provided on the third slide groove. 8 is rotatably connected to one end of the bottom of the corresponding transmission rod A6, and the rotation axis is along the front-to-back direction. A telescopic mechanism 9 is provided along the vertical direction at the bottom of the lifting frame 7, and one end of the bottom of the telescopic mechanism 9 is fixedly connected to the second slider 10. A through hole along the vertical direction is opened on the charging platform body 2, and a charging contact seat 15 is provided in the through hole. A connecting mechanism is provided between the charging contact seat 15 and the second slider 10. In this embodiment, the second slide groove 12 is a through groove, and the connecting mechanism includes a support seat 14 arranged at the bottom of the charging contact seat 15 and an "L"-shaped connecting rod 13 fixedly connected to the support seat 14, and the "L"-shaped connecting rod 13 is fixedly connected to the second slider 10 at one end away from the support seat 14.

[0024] Working principle: When the height of one end of the bottom of the telescopic mechanism 9 remains unchanged, when the telescopic mechanism 9 is extended, it drives the two push rods 1 away from each other, and when the telescopic mechanism 9 is shortened, it drives the two push rods 1 closer to each other. When the two push rods 1 are so close to each other that they can no longer get closer, the telescopic mechanism 9 continues to shorten, driving one end of the bottom of the telescopic mechanism 9 to rise, and then driving the second slider 10, the "L"-shaped connecting rod 13, the support seat 14 and the charging contact seat 15 to rise in turn.

[0025] When this embodiment is used in a specific manner, the following can be referred to in the natural state. Figure 2 At this time, the telescopic mechanism 9 and the second slider 10 are affected by gravity, and one end of the bottom of the telescopic mechanism 9 and the second slider 10 are located at one end of the bottom of the second slide groove 12. The two push rods 1 are in contact with each other, and the charging contact seat 15 is located below the two push rods 1. At this time, the push rod 1 can play a certain protective role on the charging contact seat 15 to prevent foreign objects from contacting the charging contact seat 15 at ordinary times and having an adverse effect on the charging contact seat 15.

[0026] Before landing the drone, please refer to the attached Figure 5 , control the telescopic mechanism 9 to extend, drive the lifting frame 7 to rise, make the two push rods 1 move away from each other, push the foreign objects left on the main body of the charging pad 2 to the left and right sides, so that the two push rods 1 can clean the foreign objects on the main body of the charging pad 2, and expose the charging contact seat 15 to leave a place for the drone to stop and charge.

[0027] When the drone lands on the charging pad body 2, the wireless charging module on the drone corresponds to the charging contact seat 15, which can be achieved by slowly adjusting the position of the drone through the camera on the drone, and then controlling the telescopic mechanism 9 to shorten, driving the lifting frame 7 to descend, and driving the two push rods 1 to approach each other until the two push rods 1 clamp the drone in place, and the two push rods 1 cannot continue to approach each other. As the telescopic mechanism 9 continues to shorten, one end of the bottom of the telescopic mechanism 9 rises, driving the second slider 10 to rise, and the second slider 10 drives the charging contact seat 15 to rise through the connecting mechanism until the charging contact seat 15 contacts the charging module of the drone. Since the two push rods 1 have clamped the drone in place, the charging contact seat 15 can be in close contact with the charging module, and then charging is completed. After charging is completed, the telescopic mechanism 9 is controlled to reset.

[0028] In this embodiment, the push rod 1 can protect the charging contact seat 15 at ordinary times, so as to prevent the charging contact seat 15 from being attached with metal materials or living things due to long-term unattended when the device is set up in the wild, causing adverse effects on the charging contact seat 15 and affecting charging. In addition, the charging pad body 2 is cleaned every time the drone is stopped for charging, leaving a clean position for the drone to stop for charging. In this embodiment, the charging contact seat 15 can be in close contact with the charging module, which can effectively reduce the loss of electricity during charging, has high charging efficiency, can perform wireless charging more stably, and realize intelligent remote control. In addition, all the structures in this embodiment only need to be controlled and realized through the telescopic mechanism 9, and the structure is simple and practical, which is convenient for production and daily maintenance.

[0029] It should be noted that when the device is actually used in the wild, a total charging line can be pre-buried or a solar panel can be installed to realize power supply, or the device can be equipped with a distribution box 11 for daily use.

[0030] As attached Figure 3 , Figure 4 As shown, the present embodiment also includes an elastic positioning mechanism, the elastic mechanism includes a roller 16 arranged on the side of the "L"-shaped connecting rod 13 close to the mounting plate 5, a pressure plate 17 is provided at the corresponding position of the mounting plate 5 and the roller 16 through a spring A18, and an arc groove adapted to the roller 16 is provided on the side of the pressure plate 17 close to the roller 16. Normally, the roller 16 is located in the arc groove, and pressure is generated on the roller 16 through the pressure plate 17, which plays an elastic limit role on the "L"-shaped connecting rod 13, thereby increasing the stability of the device.

[0031] As attached Figure 5 , Figure 6 , Figure 7As shown, an auxiliary positioning mechanism is also included, and the auxiliary positioning mechanism includes two auxiliary positioning devices arranged in front and behind. The auxiliary positioning device includes a positioning plate 19. The left and right sides of the positioning plate 19 are rotatably connected with transmission rods B20 respectively, and the rotating axis is along the vertical direction. The transmission rod B20 is rotatably connected with a moving plate 21 at one end away from the positioning plate 19. The rotating axis is along the vertical direction. A spring B22 is provided on the side of the moving plate 21 away from the other positioning device. The spring B22 is along the front and rear direction. A fixed plate 23 is provided at one end of the spring B22 away from the moving plate 21. A cavity is provided on the inner side of the push rod 1, and the fixed plate 23 is fixedly arranged in the cavity. In a natural state, when the two push rods 1 are close to each other, the two positioning plates 19 are close to each other.

[0032] Working principle: When the two push rods 1 move away from each other, the two positioning plates 19 move away from each other. When the drone lands, the bottom bracket of the drone falls between the two push rods 1 and the two positioning plates 19. For example, the bottom bracket of the drone can be set to a circular ring shape. When the bracket falls on the charging pad body 2, there is no need to accurately adjust the position. When the two push rods 1 are close to each other, the bracket is clamped and fixed to the center position by the two push rods 1 and the two positioning plates 19, so that the wireless charging module corresponds to the charging contact seat 15, and automatic positioning can be achieved.

[0033] It should be noted that when the bracket is clamped, the two positioning plates 19 need to contact the bracket first, and as the two push rods 1 continue to approach each other, the moving plate 21 can be adaptively displaced.

[0034] As attached Figure 1 , Figure 2 , Figure 3 , Fig. 9 As shown, in this embodiment, a protective box 4 for protecting the control mechanism is provided on the front side of the mounting plate 5 to protect the control mechanism; the telescopic mechanism 9 includes a motor 901 and a plurality of sleeves 902 that are sequentially threaded together, which occupies less space when shortened and is more flexible to use; the support plate 3 and the mounting plate 5 are detachably connected to the charging pad body 2, the push rod 1 is detachably connected to the transmission rod A6, and the connecting mechanism is detachably connected to the charging contact seat 15, and each part is detachable for easy carrying.

[0035] Embodiment 2

[0036] As attached Fig.10 As shown, the difference between this embodiment and the first embodiment is that in this embodiment, a push rod 1 is provided with a third slide groove, a third slider 8 is provided on the third slide groove, a transmission rod A6 is provided between the push rod 1 and the third slider 8, the transmission rod A6 is rotatably connected to the first slider 24, and the transmission rod A6 is always inclined to the left from top to bottom. In the natural state, when the lifting frame 7 is raised, the push rod 1 moves to the right, and the charging contact seat 15 is arranged at the top of the charging platform body 2 close to the right side.

[0037] When this embodiment is used, in a natural state, the telescopic mechanism 9 and the second slider 10 are acted upon by gravity, and one end of the bottom of the telescopic mechanism 9 and the second slider 10 are located at one end of the bottom of the second slide groove 12 , and the charging contact seat 15 is located below the push rod 1 .

[0038] Before landing the drone, please refer to the attached Fig.10 , control the telescopic mechanism 9 to extend and retract, drive the lifting frame 7 to rise and fall, and the push rod 1 to make a reciprocating motion to push the foreign matter left on the main body of the charging pad 2 to the left and right sides, so that the push rod 1 can clean the foreign matter on the main body of the charging pad 2 and expose the charging contact seat 15 to leave a position for the drone to stop and charge.

[0039] After the UAV lands on the charging pad body 2, the telescopic mechanism 9 is controlled to shorten, driving the lifting frame 7 to descend, and driving the push rod 1 to move to the left until the push rod 1 can no longer move to the left. It should be noted that a certain limit device is required to achieve this. The limit device can be a block set in the sliding mechanism to limit the position of the push rod 1 moving to the left. As the telescopic mechanism 9 continues to shorten, one end of the bottom of the telescopic mechanism 9 rises, driving the second slider 10 to rise. The second slider 10 drives the charging contact seat 15 to rise through the connecting mechanism until the charging contact seat 15 contacts the charging module of the UAV, thereby charging. After charging is completed, the telescopic mechanism 9 is controlled to reset.

[0040] Compared with the first embodiment, the present embodiment cannot clamp and position the drone, but can prevent foreign objects from falling between the two push rods 1 during charging and being unable to be cleaned. The specific structure can be flexibly selected according to actual conditions.

[0041] It should be noted that in the description of the present invention, the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings, which are only for the convenience of description, and do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0042] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0043] So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
