[0024] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it individually or selectively refer to an embodiment that is mutually exclusive of other embodiments.

[0027] Furthermore, the present invention is described in detail with reference to schematic diagrams. For ease of illustration, when describing the embodiments of the present invention, cross-sectional views illustrating device structures may be partially enlarged and not to scale. Furthermore, the schematic diagrams are merely illustrative and should not limit the scope of protection of the present invention. Furthermore, in actual production, the three-dimensional dimensions of length, width, and depth should be included.

[0028] Example 1, with reference to Figure 1 - Figure 3, which is the first embodiment of the present invention, provides a dust-proof mechanism and shock-absorbing device of a wireless charging station for an inspection drone 1, including a drone 1, a receiving plate 11 arranged on the lower side of the drone 1, and a bracket 12 arranged on the lower side of the drone 1; a charging box 2, a charging plate 21 arranged on the charging box 2; a dust-proof part 3, which is arranged in the charging box 2; a shock-absorbing part 64, which is arranged in the charging box 2 and connected to the dust-proof part 3; the drone 1 lands on the charging box 2, and the bracket 12 contacts the shock-absorbing part 64 for shock absorption. At this time, the dust-proof part 3 is opened, and the charging plate 21 and the receiving plate 11 are wirelessly docked to start charging. When the drone 1 automatically patrols, the dust-proof part 3 is closed to prevent dust accumulation on the charging plate 21.

[0029] Furthermore, the receiving plate 11 has a built-in receiving coil, and the charging plate 21 has a built-in transmitting coil. When powered, they generate an alternating magnetic field, transmitting electrical energy to the receiving plate 11. The receiving plate 11 converts the magnetic field emitted by the charging plate 21 into current through the principle of electromagnetic induction, charging the battery of the drone 1. Brackets 12 are symmetrically arranged on both sides of the bottom of the drone 1 and extend downward. When the brackets 12 land, they contact the receiving plate 42, transferring the gravity of the drone 1 to trigger the opening of the dust cover 32. The brackets 12 themselves can also be used as shock absorbers.

[0030] The storage groove 31 is opened on the inner wall on both sides of the charging plate 21, and is in the shape of a horizontal long strip. It accommodates the sliding space of the dustproof sheet 32 and provides a track for the opening and closing of the dustproof sheet 32. The dustproof sheet 32 is symmetrically embedded in the storage groove 31, and the guide rod 33 is fixed in the storage groove 31. The ring 34 slides along the guide rod 33 to limit the movement direction of the dustproof sheet 32. The receiving plate 11 ensures the linear movement of the dustproof sheet 32. The reset spring 35 connects the rings 34 on both sides to store elastic potential energy. After the drone 1 takes off, the dustproof sheet 32 is pulled back to its original position, providing power for automatic closing without the need for additional energy.

[0031] The receiving plate 42 is embedded in the slide groove 41 on both sides of the charging box 2 and can slide up and down, receiving the gravity of the drone 1 and transmitting it to the traction rope 45. The receiving plate 42 buffers the impact force of the landing of the drone 1. The connecting rod 44 and the traction rope 45 convert the downward movement of the receiving plate 42 into the lateral sliding of the dustproof sheet 32, realizing mechanical linkage and converting the gravitational potential energy into the power to open the dustproof sheet 32.

[0032] The pulley 46 is installed at the junction of the storage slot 31 and the lifting slot 43. The upper end of the traction rope 45 is fixed to the top of the connecting rod 44, passes around the pulley 46 to change direction, and the lower end is connected to the center of the dustproof sheet 32, converting the downward pressure of the receiving plate 42 into the lateral tension of the dustproof sheet 32. The arc groove 47 matches the shape of the bracket 12, enhances the landing stability, prevents the bracket 12 from slipping, and ensures precise docking.

[0033] Among them, after the drone 1 completes the inspection mission, it will automatically fly back to the charging box 2 for charging. During this process, the originally closed dustproof sheet 32 slowly opens. With the help of the automatic positioning system, the drone 1 begins to slowly descend after its receiving plate 11 is precisely aligned with the charging plate 21 of the charging box 2. As the drone 1 descends, the brackets 12 on both sides below it fall on the receiving plate 42. Under the action of its own gravity, the drone 1 applies downward pressure on the receiving plate 42, causing the receiving plate 42 to move downward. When the receiving plate 42 moves downward, the traction rope 45 is pulled by the connecting rod 44, driving the two dustproof sheets 32 to slide to both sides at the same time. At the same time, the reset spring 35 between the rings 34 on both sides is pulled in opposite directions and begins to store elastic potential energy. The charging plate 21 is then exposed. When the drone 1 descends further, the charging plate 21 successfully docks with the receiving plate 11. Based on the principle of electromagnetic induction, the transmitting coil of the charging plate 21 generates a changing magnetic field after being energized. This magnetic field generates an induced current in the receiving coil of the receiving plate 11, realizing power transmission and charging the battery of the drone 1;

[0034] When the drone 1 needs to take off again to perform an inspection mission, it takes off vertically upward, and the pressure on the receiving plate 42 disappears. Through the transfer of force, the dustproof sheet 32 is now only subjected to the contraction force of the return spring 35. Under the action of the elastic force, the dustproof sheet 32 quickly returns to its original position, closing the external contact port of the charging plate 21. When the drone 1 is not charging, the dustproof sheet 32 is in the closed state, which effectively prevents dust and debris from entering the charging box 2, preventing these foreign objects from contaminating and damaging the charging plate 21, and ensuring that the charging plate 21 is always in good working condition.

[0035] Example 2, reference Figure 3 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: when the drone 1 automatically returns to the charging box 2 for energy replenishment, the receiving plate 42 plays a shock-absorbing role with the help of the return spring 35 and the traction rope 45.

[0036] When the drone 1 lands and the brackets 12 on both sides below it begin to contact the receiving plate 42, the drone 1 has a certain descending speed, which will produce a large impact force on the receiving plate 42. At this time, the receiving plate 42, as a component that directly contacts the drone 1, bears the brunt of this force.

[0037] Under the influence of the drone's own gravity and the impact of the descent, the receiving plate 42 begins to move downward. This downward movement exerts tension on the traction rope 45 through the connecting rod 44. The traction rope 45 connects the dust shield 32 and the collar 34 on either side, which in turn connects to the return spring 35. When the traction rope 45 is pulled, the return spring 35 between the collars 34 on both sides is pulled in opposite directions, causing it to begin to stretch.

[0038] As the return spring 35 is stretched, it converts some of the kinetic energy generated by the landing drone 1 into stored elastic potential energy. This reduces the impact force exerted by the drone 1 on the docking plate 42 and prevents direct transmission of the impact force to the internal structure of the charging box 2, thereby providing a shock-absorbing effect. This protects the drone 1 and charging box 2, reducing the risk of damage due to excessive impact.

[0039] Example 3, reference Figure 4 , which is the third embodiment of the present invention, adds a second stage of shock absorption on the basis of embodiment 1.

[0040] When the drone 1 lands at a relatively high speed, the receiving plate 42 first absorbs part of the impact force. However, if the impact is relatively large, the shock absorbing plate 51 will act as a second line of defense to further cushion the impact.

[0041] The shock-absorbing plate 51 is rotatably connected in the reset groove 5. The inclination angle of the shock-absorbing plate 51 is greater than the inclination angle of the side of the charging box 2, so that the shock-absorbing plate 51 protrudes more than the side of the charging box 2, ensuring that the bracket 12 contacts the shock-absorbing plate 51 first rather than directly hitting the charging box 2. The shock-absorbing plate 51 protrudes slightly in the reset groove 5, and the shock-absorbing spring 52 is in a pre-extended state.

[0042] First stage of shock absorption: the bracket 12 contacts the receiving plate 42, the receiving plate 42 moves downward, and the dustproof sheet 32 is opened by the pulling rope 45;

[0043] Second stage shock absorption: If the impact is large, the bracket 12 continues to press down, touching the shock absorbing plate 51, compressing the shock absorbing spring 52, and further absorbing energy.

[0044] After the drone 1 takes off, the shock absorbing spring 52 rebounds, pushing the shock absorbing plate 51 to return to its original state.

[0045] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
