Description

Technical Field

[0001] The utility model relates to the field of drone football, in particular to a housing structure of drone football. Background Art

[0002] A drone is a small aircraft, usually used for short-distance observation to replace manual observation. Existing small drones are widely used, and there are also interesting drone football games to enrich the lives of the public.

[0003] For existing drone football, its spherical protective frame is an injection-molded flexible outer frame, generally divided into two hemispherical shells. A connecting ring is provided on the splicing side of the two shells. Currently, most connecting rings are only provided with vertically aligned threaded holes for installing bolts to lock and fix the two shells. Since the shell uses a lightweight injection-molded material, the internal thread of the threaded hole is easily worn and damaged after frequent disassembly and assembly actions of the bolts, thereby shortening the service life of the shell. In addition, this threaded connection method requires a screwdriver to be rotated and tightened during locking. Since the threaded holes are often arranged inside the connecting ring to avoid affecting the flight of the drone football, the tightening operation of the bolts is not convenient enough. Summary of the Utility Model

[0004] The utility model provides a housing structure of drone football, which is beneficial to solving the problems that the connection structure of some existing drone football housings uses threaded holes and bolts, resulting in difficult disassembly and assembly and easy structural wear and damage.

[0005] The utility model is realized as follows:

[0006] A housing structure of drone football includes a detachable upper housing and a lower housing. The bottom of the upper housing is provided with a first connecting ring of a horizontal annular structure, and the top of the lower housing is provided with a second connecting ring of a horizontal annular structure. A plurality of insertion posts are symmetrically arranged at the bottom of the first connecting ring in a central symmetry manner. The bottom of the insertion post is provided with a plug of a trapezoidal structure with a wider top and a narrower bottom. Clamping edges are formed on the left and right sides of the top of the plug. The top of the second connecting ring is provided with slots corresponding to the insertion posts one by one. Limiting members are arranged on the left and right side walls in the slots. A spring is arranged between the limiting member and the second connecting ring. The telescopic direction of the spring is horizontally left and right. The inner end of the limiting member is a top bead extending into the slot. When an acting force exceeding a threshold value is applied to insert and pull out the insertion post from the slot, the left and right side walls of the plug form a squeezing structure for the top bead to move outwards relative to the slot. After the insertion post is inserted into the slot in place, the top bead moves inwards relative to the slot and forms an anti-detachment structure for the insertion post with the clamping edge.

[0007] On the basis of the above technical solution, the upper housing and the lower housing are provided with uniformly distributed hollow structures.

[0008] On the basis of the above technical solution, the upper shell and the first connection ring are of an integral structure, and the lower shell and the second connection ring are of an integral structure.

[0009] On the basis of the above technical solution, a first jack is provided on the plug, and a second jack adapted to the first jack is provided on the side wall of the slot. The first jack and the second jack penetrate through the side walls of the plug and the slot in the front-rear direction respectively; after the plug post is inserted into the slot in place, the first jack and the second jack are aligned to form a combined perforation, and a plug pin is inserted into the combined perforation.

[0010] On the basis of the above technical solution, the plug pin is in interference fit with the combined perforation.

[0011] On the basis of the above technical solution, a pull ring is provided at one end of the plug pin, and a wrapping member made of an elastic material is provided on the rod body of the plug pin. After the plug pin is inserted into the combined perforation, the wrapping member forms an anti-detachment structure between the plug pin and the combined perforation.

[0012] On the basis of the above technical solution, movable cavities are provided on the left and right side walls of the second connection ring near the opening of the slot. The limiting member is movably arranged in the movable cavity. One side of the top bead extends into the slot, and a turning edge is provided on the side away from the top bead. The turning edge and the opening of the movable cavity form a limiting structure.

[0013] On the basis of the above technical solution, a limiting groove is provided on the side of the limiting member away from the top bead. One end of the spring is arranged in the limiting groove, and the other end abuts against the side wall of the second connection ring.

[0014] On the basis of the above technical solution, a detachable sealing plate is provided at the top of the movable cavity.

[0015] On the basis of the above technical solution, limiting posts are provided on the inner side wall of the movable cavity. The limiting posts and the limiting groove cooperate to form a double-sided limiting structure for the spring.

[0016] Compared with the prior art, the present utility model has at least the following advantages:

[0017] By improving the splicing structure of the upper shell and the lower shell, the present utility model uses a plug post, a slot and a limiting member to form a convenient plug-in connection structure.

[0029] The present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] Embodiment 1: With reference to Figures 1-4 , this embodiment discloses a housing structure for a drone football, aiming to solve the problems of inconvenient operation and shortened service life of the existing drone football housing structure caused by the use of threaded holes and bolts for connection.

[0031] Specifically, the housing structure in this embodiment includes a detachable upper housing 100 and a lower housing 200. The upper housing 100 and the lower housing 200 are provided with a uniformly distributed hollow structure. The upper housing 100 and the lower housing 200 are integrally formed by an injection molding process, which is not only convenient for processing but also beneficial to improving the lightweight of the product.

[0032] The bottom of the upper housing 100 is provided with a first connecting ring a with a horizontal annular structure. The top of the lower housing 200 is provided with a second connecting ring b with a horizontal annular structure. The upper housing 100 and the first connecting ring a are of an integral structure, and the lower housing 200 and the second connecting ring b are of an integral structure. The upper housing 100 and the lower housing 200 are connected by the splicing of the first connecting ring a and the second connecting ring b. After splicing, a complete spherical housing structure is formed to wrap the drone inside to play a protective effect.

[0033] Further, 8 insertion posts 1 are symmetrically arranged at the bottom of the first connecting ring a in a central symmetry manner. The thickness of the insertion posts 1 is less than the thickness of the first connecting ring a. With reference to Figure 2 , the bottom of the insertion post 1 is provided with a plug 11 with a trapezoidal structure that is wider at the top and narrower at the bottom. The left and right sides of the top of the plug 11 form clamping edges 12 (with reference to Figure 4As shown, the card edge 12 can form a unilateral limiting structure for the insertion post 1. Correspondingly, the top of the second connecting ring b is provided with a slot 2 corresponding to the insertion post 1 one by one. The top of the slot 2 forms an opening structure on the top of the second connecting ring b for the insertion post 1 to be inserted downward.

[0034] On the left and right side walls of the slot 2, there are limiting members 3. Between the limiting member 3 and the second connecting ring b, there is a spring 33. The telescopic direction of the spring 33 is horizontally left and right. The inner end of the limiting member 3 is a top bead 31 extending into the slot 2; when an acting force exceeding the threshold is applied to insert and pull out the insertion post 1 from the slot 2, the left and right side walls of the plug 11 form a squeezing structure for the top bead 31 to move outward relative to the slot 2; after the insertion post 1 is inserted into the slot 2 in place, the top bead 31 moves inward relative to the slot 2 and forms an anti-dropping structure for the insertion post 1 with the card edge 12.

[0035] Specifically, in combination with Figure 3 and Figure 4 , on the left and right side walls of the second connecting ring b near the opening of the slot 2, there are movable cavities 8. The movable cavities 8 are used to accommodate the limiting members 3 for horizontal left and right displacement. The limiting members 3 are movably arranged in the movable cavities 8. One side of the top bead 31 extends into the slot 2, and there is a turned edge on the side away from the top bead 31. The turned edge and the opening of the movable cavity 8 form a limiting structure to prevent the limiting member 3 from falling off from the movable cavity 8 into the slot 2.

[0036] On the side of the limiting member 3 away from the top bead 31, there is a limiting groove 32. One end of the spring 33 is arranged in the limiting groove 32, and the other end abuts against the side wall of the second connecting ring b. On this side wall, there is a limiting post 4. The limiting post 4 and the limiting groove 32 jointly form a bilateral limiting structure for the spring 33, which makes the installation position of the spring 33 stable and reliable, and can stably perform horizontal left and right telescopic activities to help the limiting member 3 perform elastic outward or inward displacement and reset.

[0037] To facilitate the installation of the limiting member 3, the top of the movable cavity 8 is provided with a detachable sealing plate 5. In this embodiment, the sealing plate 5 is locked on the second connecting ring b by screws.

[0038] Further, in combination with Figures 2-4 , the plug 11 is provided with a first jack 13, and the side wall of the slot 2 is provided with a second jack 21 adapted to the first jack 13. The first jack 13 and the second jack 21 respectively penetrate through the side walls of the plug 11 and the slot 2 in the front and rear directions; after the insertion post 1 is inserted into the slot 2 in place, the first jack 13 and the second jack 21 are aligned to form a combined perforation, and a pin 6 is inserted into the combined perforation. As Figure 5 shown, the function of the pin 6 is to further improve the connection strength between the first connecting ring a and the second connecting ring b and prevent loosening.

[0039] Among them, the plug 6 is in interference fit with the combined perforation, which also prevents the plug 6 from falling off easily after installation, so as to ensure that the structure of the drone football can remain stable during activities.

[0040] To facilitate the force application for inserting and pulling out the plug 6, as Figure 5 shown, a pull ring is provided at one end of the plug 6. The pull ring in this embodiment is in a circular ring structure. After installation, the pull ring is located inside or outside the shell and can be flexibly selected according to the actual application scenario.

[0041] Embodiment 2: In order to make the insertion of the plug 6 more firm and reliable, a wrapping member 7 made of an elastic material (rubber with a thickness of 0.3 mm in this embodiment) is provided on the rod body of the plug 6. After the plug 6 is inserted into the combined perforation, the wrapping member 7 forms an elastic filling structure between the plug 6 and the combined perforation, and then forms an anti-detachment structure, making the insertion of the plug 6 more firm and reliable.

[0042] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
