[0061] Embodiment

[0062] This embodiment provides a drone homing device, as Figures 1 to 6 shown, including: a bottom plate 1, a homing structure 2, and a transmission structure 3. The homing structure 2 includes: a first homing component 21 and a second homing component 22. There are two of each of the first homing component 21 and the second homing component 22. The two first homing components 21 are symmetrically arranged relative to a first axis passing through the parking position, as Figure 3 shown, that is, the first axis is a horizontal line passing through the center of the parking position. The two second homing components 22 are symmetrically arranged relative to a second axis passing through the parking position. The second axis is a vertical line passing through the center of the parking position. The first axis and the second axis are perpendicular to each other;

[0063] Specifically, the bottom plate 1 includes a parking surface and a structure assembly surface. A parking position is provided on the parking surface. The transmission structure 3 is all arranged on the structure assembly surface.

[0064] As Figure 3 and Figure 4 shown, there are four transmission structures 3. The four transmission structures 3 are arranged in a circular array centered on the center of the parking position; as Figure 3As shown, four transmission structures 3 are respectively arranged on the left side, right side, top and bottom of the parking position. Among them, the transmission structures 3 on the top and bottom are used to install the first homing assembly 21, and the transmission structures 3 on the left and right are used to install the second homing assembly 22. The four transmission structures 3 include four transmission wheels 31 and four tensioning wheel assemblies 32. The four transmission wheels 31 are respectively arranged on the left side, right side, top and bottom of the parking position. The center of the left transmission wheel 31 and the center of the right transmission wheel 31 are located on the first axis, the center of the upper transmission wheel 31 and the center of the lower transmission wheel 31 are located on the second axis, and the distance between the centers of the four transmission wheels 31 and the center of the parking position is equal. The four tensioning wheel assemblies 32 are arranged in a circular array at the center of the parking position at the middle position of the structural assembly surface corresponding to the parking position. The four tensioning wheel assemblies 32 are respectively arranged in a one-to-one correspondence with the four transmission wheels 31, and each tensioning wheel assembly 32 is closer to the center of the bottom plate 1 than the corresponding transmission wheel 31.

[0065] Specifically, Figure 4 As shown, the tensioning wheel assembly 32 includes a tensioning fixed member 321, a tensioning movable member 322 and a tensioning wheel 323. The tensioning fixed member 321 is connected to the bottom plate 1 on the side of the sliding groove 11; the tensioning movable member 322 is installed in the sliding groove 11, and the top of the tensioning movable member 322 abuts against the tensioning fixed member 321. The adjusting member 324 passes through the tensioning fixed member 321 and is connected to the tensioning movable member 322 to adjust the position of the tensioning movable member 322; the tensioning wheel 323 is rotatably installed on the tensioning movable member 322. The specific structure is explained by taking one of the transmission wheels 31 and the tensioning wheel assembly 32 corresponding to the transmission wheel 31 as an example, and the other transmission wheels 31 and tensioning wheel assemblies 32 are only different in the installation direction. The upper transmission wheel 31 is provided with a sliding groove 11 on the structural assembly surface at the back of the parking position, and the sliding groove 11 is opened along the second axial direction. The tensioning fixing piece 321 is in an inverted U shape as a whole. The tensioning fixing piece 321 is covered on the sliding groove 11. The two ends of the tensioning fixing piece 321 are respectively fixed on the bottom plate 1 at the two ends of the sliding groove 11 along the second axial direction. The top inner wall of the tensioning fixing piece 321 corresponds to the sliding groove 11 and has a limiting groove; the tensioning movable piece 322 is in a "匚" shape as a whole. The opening of the tensioning movable piece 322 faces downward away from the corresponding upper transmission wheel 31, the top end abuts in the limiting groove, and the bottom end abuts in the sliding groove 11. The adjusting piece 324 passes through the tensioning fixing piece 321 and is connected to the tensioning movable piece 322; the tensioning wheel 323 is rotatably mounted on the tensioning movable piece 322.

[0066] like Figure 3 and Figure 5As shown, the inner side of the synchronous belt 4 is toothed, and the driving wheel 31 is a gear adapted to the tooth shape on the inner side of the synchronous belt 4. The synchronous belt 4 is successively installed on the driving wheel 31 and the tensioning wheel 323. Starting from the upper driving wheel 31 and along the counterclockwise direction, the inner side of the synchronous belt 4 meshes with the upper driving wheel 31. The synchronous belt 4 extends downward, and the outer side of the synchronous belt 4 fits and abuts against the upper left tensioning wheel 323 among the four middle tensioning wheels 323 corresponding to the upper driving wheel 31; the synchronous belt 4 extends leftward, the inner side of the synchronous belt 4 is sleeved and meshed with the left driving wheel 31, the synchronous belt 4 extends rightward, and the outer side of the synchronous belt 4 fits and abuts against the lower left tensioning wheel 323 among the four middle tensioning wheels 323 corresponding to the left driving wheel 31; the synchronous belt 4 extends downward, the inner side of the synchronous belt 4 is sleeved and meshed with the lower driving wheel 31, the synchronous belt 4 extends upward, and the outer side of the synchronous belt 4 fits and abuts against the lower right tensioning wheel 323 among the four middle tensioning wheels 323 corresponding to the lower driving wheel 31; the synchronous belt 4 extends rightward, the inner side of the synchronous belt 4 is sleeved and meshed with the right driving wheel 31, the synchronous belt 4 extends leftward, and the outer side of the synchronous belt 4 fits and abuts against the upper right tensioning wheel 323 among the four middle tensioning wheels 323 corresponding to the right driving wheel 31; the synchronous belt 4 extends upward, and the inner side of the synchronous belt 4 meshes with the upper driving wheel 31. The synchronous belt 4 forms a "cross"-shaped closed structure.

[0067] As Figure 4 shown, the adjusting member 324 is an adjusting screw. When the synchronous belt 4 is wound around the four driving wheels 31 and the four tensioning wheels 323, it is necessary to ensure that any synchronous belt 4 between the tensioning wheel 323 and the corresponding driving wheel 31 is parallel to the first axis or the second axis. The tensioning wheel 323 not only provides a steering function. By adjusting the adjusting member 324, the tensioning wheel 323 moves toward the direction close to its corresponding driving wheel 31, and the distance between the tensioning wheel 323 and the corresponding driving wheel 31 is reduced, which is convenient for the installation of the closed synchronous belt 4. After the installation is completed, the adjusting member 324 is adjusted in the opposite direction to drive the tensioning wheel 323 to move in the opposite direction to tension the synchronous belt 4. After reaching the appropriate position, the adjustment is stopped, so that the synchronous belt 4 forms a closed "cross"-shaped closed structure. And the tightness of the synchronous belt 4 can be quickly adjusted by screws, and the operation is simple.

[0068] In this embodiment, the upper and lower two drive structures 3 among the four drive structures 3 are connected to the first return component 21; the left and right two drive structures 3 are connected to the second return component 22.

[0069] The bottom plate 1 is provided with a first moving groove 12 along the direction where the second axis is located, as Figure 2 and Figure 3As shown in the figure, there are four first moving slots 12. The four first moving slots 12 are vertically opened. Two first moving slots 12 are symmetrically and spaced apart above the bottom plate 1, and two first moving slots 12 are symmetrically and spaced apart below the bottom plate 1. There are two first return components 21. The two first return components 21 are respectively arranged on the upper and lower sides of the bottom plate 1. Taking one of them as an example to illustrate the structure of the first return component 21, the first return component 21 includes: a first return rod 211 and a first push rod 212. The first return rod 211 is arranged on the stop surface. The first push rod 212 is arranged on the side of the bottom plate 1 away from the stop surface. A first mounting portion is arranged on the side of the first push rod 212 close to the first return rod 211. The first mounting portion passes through the first moving slot 12 and is connected to the first return rod 211. The drone return device further includes a first slide rail 61. The first slide rail 61 is installed on the bottom plate 1 along the extension direction of the second axis, that is, the first slide rail 61 is vertically arranged between the two first moving slots 12 above or below. A first slider 62 is arranged on the first slide rail 61. The first slider 62 is also connected to the first push rod 212. The first slider 62 is fixed on the synchronous belt 4.

[0070] The bottom plate 1 is provided with a second moving slot 13 along the direction of the first axis. As Figure 2 and Figure 3 shown, there are four second moving slots 13. The four second moving slots 13 are vertically opened. Two second moving slots 13 are symmetrically and spaced apart on the left side of the bottom plate 1, and two first moving slots 12 are symmetrically and spaced apart on the right side of the bottom plate 1. There are two second return components 22. The second return component 22 includes: a second return rod 221 and a second push rod 222. The second return rod 221 is arranged on the stop surface. The second push rod 222 is arranged on the side of the bottom plate 1 away from the stop surface. A second mounting portion is arranged on the side of the second push rod 222 close to the second return rod 221. The second mounting portion passes through the second moving slot 13 and is connected to the second return rod 221. The drone return device further includes a second slide rail 63. The second slide rail 63 is installed on the bottom plate 1 along the extension direction of the second axis, that is, the first slide rail 61 is vertically arranged between the two second moving slots 13 on the left or right side. A first slider 62 is arranged on the first slide rail 61. The first slider 62 is also connected to the first push rod 212. The first slider 62 is fixed on the synchronous belt 4.

[0071] As Figure 3 shown, the upper first slide rail 61 is arranged on the left side of the upper synchronous belt 4, the lower first slide rail 61 is arranged on the right side of the lower synchronous belt 4, the left second slide rail 63 is arranged below the left synchronous belt 4, and the right second slide rail 63 is arranged above the right synchronous belt 4. The slider on each slide rail is fixed on the conveyor belt close to it.

[0072] As Figure 3As shown, the driving member 5 is fixed on the bottom plate 1. The output end of the driving member 5 is connected to one of the transmission wheels 31. The driving member 5 is a rotating motor. When it is necessary to clamp and fix the drone 8 at the parking position for charging, the driving member 5 is started. The driving member 5 drives the transmission wheel 31 to rotate counterclockwise, and then drives the two first sliders 62 and the two second sliders 64 fixed thereon to move along the corresponding first slide rail 61 or the second slide rail 63 simultaneously towards the direction close to the tension wheel 323; the two first sliders 62 drive the two first return rods 211 to move along the first moving groove 12 towards the direction close to the parking position through the first push rod 212 and the first mounting portion, and the two second sliders 64 drive the two second return rods 221 to move along the second moving groove 13 towards the direction close to the parking position through the second push rod 222 and the second mounting portion, so as to clamp the drone 8 at the parking position. Through the above settings, the simultaneous centering and returning in four directions can be realized by using one motor, and the tension wheel assemblies 32 are designed in all four directions, which is convenient for assembly and tension adjustment. Generally speaking, the structure of this solution is simple and the maintenance cost is relatively low.

[0073] In other feasible embodiments, such as Figure 6 As shown, the drone returning device further includes a charging structure 7. The charging structure 7 includes: a housing 71, a charging module 72, an elastic telescopic member 73 and a sucking member 74. The housing 71 is installed on the upper surface of the second return rod 221. A receiving cavity is provided in the housing 71. One side of the housing 71 close to the parking position is provided with a telescopic groove, and the telescopic groove is communicated with the receiving cavity; the charging module 72 is installed in the receiving cavity; the elastic telescopic member 73 is arranged at one end of the charging module 72 away from the parking position. One end of the elastic telescopic member 73 is connected to the charging module 72, and the other end is fixed on the inner wall of the housing 71; the sucking member 74 is fixed on the inner wall of the charging module 72 on the side away from the parking position. The sucking member 74 is an electromagnet, and an iron sheet is installed on the outer shell of the charging module 72. The elastic telescopic member 73 is composed of a guide post and a spring sleeved on the guide post.

[0074] When the first return rod 211 and the second return rod 221 move towards the parking position, it is necessary to start the sucking member 74. The sucking member 74 sucks the iron sheet by magnetic force, compresses the spring, and the charging module 72 moves along the guide post towards the direction away from the telescopic groove, adsorbing the whole charging module 72 into the receiving cavity to prevent the charging module 72 from colliding with the drone 8 during the returning process. After the returning is completed, the sucking member 74 is powered off, and the elastic telescopic member 73 drives the charging head of the charging module 72 to extend out of the telescopic groove, and the male head of the charging module 72 is automatically adsorbed to the female head magnet of the drone 8 to complete charging.

[0075] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation manners here. And the obvious changes or modifications derived therefrom still fall within the protection scope of this utility model creation.
