DETAILED DESCRIPTION

[0031] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0032] It should be understood that the terms "upper", "lower", "left", "right", "front", "back", "middle", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the utility model.

[0033] like Figure 2 and Figure 3 As shown, a recovery positioning mechanism 1 provided in the first embodiment of the present invention includes a support base 11 and a plurality of positioning components 12; the support base 11 is provided with a plurality of guide bevels 111 distributed in a ring-shaped manner around a preset center line; it can be understood that the number of the guide bevels 111 and the positioning components 12 can be set according to actual needs (for example, 2, 3, etc.); the extension lines of all the guide bevels 111 are compared to a point on the preset center line.

[0034] The positioning assembly 12 includes a slider 121 and an elastic member 122. The sliders 121 are slidably mounted in the guide chute 111 in a one-to-one correspondence. The elastic members 122 are mounted in the guide chute 111 in a one-to-one correspondence. Each elastic member 122 abuts between the bottom surface of the guide chute 111 and the slider 121. It is understood that the elastic member 122 includes but is not limited to a spring, etc., and the elastic member 122 abuts against the bottom of the slider 121. The positioning assemblies 12 are mounted in the guide chute 111 in a one-to-one correspondence.

[0035] Each of the sliders 121 is provided with a positioning portion 1211 at one end away from the elastic member 122. When all the sliders 121 slide from top to bottom in the guide groove 111, all the positioning portions 1211 are located on the same base circle with the preset center line as the center, and the radius of the base circle gradually increases.

[0036] Specifically, if Figures 4 to 7 As shown, when the landing gear 22 of the aircraft 2 falls on the slider 121, the slider 121 will move downward in the guide chute 111 and compress the elastic member 122, and the multiple sliders 121 will separate from each other. In the process of separation of the multiple sliders 121, all the positioning parts 1211 are located on the same base circle with the preset center line as the center of the circle, until the positioning part 1211 abuts against the inner wall of the positioning hole 221 on the landing gear 22. Since the multiple positioning parts 1211 are on the same base circle, the multiple sliders 121 can complete the function of automatic centering and positioning of the aircraft 2, thereby solving the configuration deviation, imbalance and other problems existing in each recovery and positioning process of the aircraft 2, and ensuring the position accuracy of the aircraft 2 landing on the recovery and positioning mechanism 1.

[0037] When the aircraft 2 flies away from the slider 121, the rebound force of the elastic member 122 drives the slider 121 to move upward in the guide chute 111, and the multiple sliders 121 are closed above the support base 11. In the present invention, the recovery and positioning mechanism 1 has a simple structure and low manufacturing cost.

[0038] In one embodiment, if Figure 2 and Figure 3 As shown, the support seat 11 is also provided with an internal space 112, and the recovery positioning mechanism also includes a skeleton 14 and a guide column 13 installed in the internal space 112; the preset center line coincides with the axis of the guide column 13; it can be understood that the guide column 13 is the symmetry center of the multiple guide bevels 111, that is, the distance between each guide bevel 111 and the guide column 13 is equal.

[0039] The skeleton 14 includes a sleeve 141 and a plurality of side plates 142 connected to the outer wall of the sleeve 141 . The sleeve 141 is slidably sleeved on the guide post 13 , and the side plates 142 are connected to the sliders 121 in a one-to-one correspondence.

[0040] Specifically, when the slider 121 slides in the guide groove 111, the slider 121 drives the sleeve 141 to slide along the guide column 13 through the side plate 142. The guide column 13 can limit the multiple sliders 121 on the same base circle through the skeleton 14, thereby ensuring the stability of the multiple sliders 121 separating and closing from each other.

[0041] In one embodiment, if Figure 3 and Figure 6 As shown, a first through hole 113 communicating with the internal space 112 is provided on the inner wall of the guide chute 111, and a plug-in slot 1212 is provided on the slider 121. The end of the side plate 142 away from the sleeve 141 passes through the first through hole 113 and then slides and plugs into the plug-in slot 1212. It can be understood that the first through hole 113 is a long strip through hole, and the guide chute 111 is a long strip groove. Specifically, when the slider 121 slides in the guide chute 111, the slider 121 drives the sleeve 141 to slide along the guide column 13 through the side plate 142, and the side plate 142 slides in the plug-in slot 1212, so that multiple sliders 121 can be separated from or closed together.

[0042] In one embodiment, if Figure 2 and Figure 3 As shown, the support base 11 also has an opening that connects to the internal space 112. The recovery and positioning mechanism 1 includes a cover plate 15, on which the guide post 13 is mounted. The cover plate 15 is mounted on the support base 11 and serves to block the opening. It is understood that the opening is provided at the bottom of the support base 11, and the guide post 13 and the bottom cover are integrally formed. In this embodiment, the cover plate 15 allows access to the internal space 112, thereby facilitating the assembly and disassembly of the recovery and positioning mechanism 1.

[0043] In one embodiment, if Figure 3 As shown, the end of the slider 121 away from the elastic member 122 is further provided with a support surface 1213 and a limit surface 1214, and the positioning portion 1211 is arranged between the support surface 1213 and the limit surface 1214. It can be understood that the support surface 1213 and the limit surface 1214 are both arranged on the top surface of the slider 121 and are arranged in a stepped shape.

[0044] Specifically, the landing gear 22 of the aircraft 2 lands on the support surface 1213, the slider 121 moves downward along the guide inclined groove 111, and the multiple sliders 121 separate from each other until the positioning portion 1211 abuts against the inner wall of the positioning hole 221 on the landing gear 22, and the positioning steps on the multiple sliders 121 are on the same base circle, so that the recovery positioning mechanism 1 completes the automatic centering function of the aircraft 2.

[0045] In one embodiment, if Figure 1 As shown, the support seat 11 includes a frustum 114 and a base 115 connected to the frustum 114; the diameter of the frustum 114 gradually decreases from the end close to the base 115 toward the end away from the base 115; it can be understood that the frustum 114 and the base 115 are an integrally formed part, the diameter of the top of the frustum 114 is smaller, and the diameter of the bottom of the frustum 114 is larger, and the internal space 112 is set on the frustum 114 and the base 115.

[0046] The guide chute 111 includes a side groove 1111 provided on the truncated platform 114 and a receiving groove 1112 provided on the base 115. The side groove 1111 communicates with the receiving groove 1112, and the elastic member 122 is installed in the receiving groove 1112. It can be understood that the opening of the receiving groove 1112 faces upward, and the side groove 1111 is provided on the side wall of the truncated platform 114.

[0047] Specifically, when the slider 121 slides from the side groove 1111 to the accommodating groove 1112, the limiting surface 1214 is flush with the top surface of the base 115. At this time, the landing gear 22 of the aircraft 2 will completely land on the recovery positioning mechanism 1, and the inner wall of the positioning hole 221 on the landing gear 22 abuts against the outer wall of the base 115, ensuring the stability of the aircraft 2 landing on the recovery positioning mechanism 1.

[0048] In one embodiment, if Figure 3 As shown, the base 115 is further provided with a notch 1151 communicating with the receiving groove 1112. The notch 1151 is located on a side of the receiving groove 1112 away from the preset centerline. A limiting protrusion 1215 is provided on a side wall of the slider 121 away from the preset centerline. The limiting protrusion 1215 is disposed opposite the notch 1151. It is understood that the notch 1151 communicates with the side of the receiving groove 1112.

[0049] Specifically, when the slider 121 is inserted into the accommodating groove 1112, the limiting protrusion 1215 is embedded in the notch 1151, and the limiting surface 1214 is flush with the top surface of the base 115. The limiting protrusion 1215 can fill the notch 1151, and the limiting protrusion 1215 also has a portion located outside the positioning hole 221 of the landing gear 22, so that multiple sliders 121 can lock the landing gear 22 on the support seat 11, further ensuring the stability of the aircraft 2 landing on the recovery positioning mechanism 1.

[0050] In one embodiment, if Figure 1 As shown, the recovery and positioning mechanism 1 further includes a mobile trolley 16, and the support base 11 is mounted on the mobile trolley 16. It is understood that the mobile trolley 16 is provided with a motor and wheels, and the mobile trolley 16 can drive the support base 11 and the positioning assembly 12 thereon to move, thereby realizing the on-board recovery and positioning function of the aircraft 2.

[0051] In one embodiment, if Figure 3 As shown, the guide chute 111 is provided with a first guide slope; in a cross section parallel to the horizontal plane, the vertical distances between all first guide slopes and the predetermined centerline are equal. The slider 121 is provided with a second guide slope that slidably abuts against the first guide slope. It can be understood that the slider 121 moves within the guide chute 111 by virtue of the first and second guide slopes abutting against each other, ensuring the stability of the slider 121's sliding within the guide chute 111.

[0052] like Figure 1 As shown, another embodiment of the present invention further provides a flying device, including an aircraft 2 and the above-mentioned recovery and positioning mechanism 1, wherein the aircraft 2 includes an aircraft body 21 and a landing gear 22 installed on the aircraft body 21, and a positioning hole 221 is provided on the landing gear 22, and the radius of the positioning hole 221 is equal to the maximum radius of the base circle.

[0053] Specifically, when the landing gear 22 of the aircraft 2 lands on the slider 121 (the bottom surface of the landing gear 22 abuts the support surface 1213), the positioning hole 221 on the landing gear and the recovery positioning mechanism are not necessarily in a centered state; the slider 121 will move downward in the guide chute 111 and compress the elastic member 122, and the multiple sliders 121 will separate from each other. In the process of separation of the multiple sliders 121, all the positioning portions 1211 are located on the same base circle with the preset center line as the center, until the positioning portion 1211 abuts the inner wall of the positioning hole 221 on the landing gear 22. Since the multiple positioning portions 1211 are on the same base circle, the multiple sliders 121 can complete the automatic centering function of the aircraft 2, thereby solving the configuration deviation, imbalance and other problems existing in each recovery positioning process of the aircraft 2, and ensuring the position accuracy of the aircraft 2 landing on the recovery positioning mechanism 1; and the recovery positioning mechanism 1 has a simple structure and low manufacturing cost.

[0054] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
