However, the quick-detachable structure of this scheme is large in size, which will take up more mounting space, and when the structure is exposed to the air during operation, it will increase a certain amount of aerodynamic resistance.

[0005] The Chinese patent announcement number is CN210027954U, and the announcement date is February 7, 2020. The utility model patent named "A UAV optical pod quick-release device" discloses that the pod is fixed by a new locking piece and mounting ears, while eliminating the operation of plugging and unplugging cables. However, the solution has a complex structure and cannot be operated with one hand, which affects the user experience. Utility Model Content

[0035] Hereinafter, embodiments of the present utility model will be described with reference to the accompanying drawings. In the following description, the same modules are represented by the same reference numerals. In the case of the same reference numerals, their names and functions are also the same. Therefore, the detailed description thereof will not be repeated.

[0036] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and do not constitute a limitation of the utility model.

[0037] like Figure 1 and Figure 2 As shown, the pod quick disassembly and assembly structure provided by the embodiment of the utility model includes: a base 1, a support frame 2, a pressing member 3, an elastic member 4, a buckle 5, an upper cover 6 and a connector 7, wherein the base 1 is in the shape of a smooth cylinder with an open upper bottom surface, which is used to reduce the wind resistance caused by the quick disassembly and assembly structure during the flight of the drone. A "cross"-shaped support frame 2 is arranged inside the base 1, and the support frame 2 is composed of two reinforcing ribs that are perpendicular to each other and connected at the midpoint position. The four ends of the support frame 2 are fixed on the inner wall of the base 1. The arrangement of the support frame 2 can greatly improve the impact resistance and load-bearing capacity of the pod quick disassembly and assembly structure, and avoid the deformation of the base 1 due to bumps or excessive weight of the mounted pod, so that the quick disassembly and assembly function cannot be smoothly realized. In the support frame 2, at least one reinforcing rib has an open accommodating cavity on both sides of the midpoint position. A pair of pressing holes 101 are provided on the side wall of the base 1. Both pressing holes 101 are circular holes. The two pressing holes 101 are at the same height on the side wall of the base 1 and are arranged on the same straight line passing through the axis of the base 101. The positions of the two pressing holes 101 correspond exactly to the external positions of the two open accommodating cavities. The setting of the pressing holes 101 is to realize the installation and movement of the pressing member 3. Figure 3As shown, the pressing member 3 is a cylindrical structure and passes through the pressing hole 101. Two grooves 301 of equal height are opened on both sides of the pressing member 3. Guide strips 201 matched with the grooves 301 are provided on the two inner sides of each open accommodating cavity. The pressing member 3 passes into the open accommodating cavity along the pressing hole 101, and the guide strips 201 are embedded in the grooves 301, so as to ensure that the pressing member 3 reciprocates along the guide strips 201, and avoid the problems of displacement, rotation or separation of the pressing member 3 during the movement. In addition, a blind hole 302 along the axial direction of the pressing member 3 is opened on the surface of the pressing member 3 facing the inside of the base 1. The support frame 2 and the pressing member 3 are connected by an elastic member 4, one end of the elastic member 4 is arranged in the blind hole 302, and the other end abuts on the inner side of the open accommodating cavity close to the axis of the base 1. The elastic member 4 adopts an existing stainless steel coil spring.

[0038] As a preferred embodiment, a first column 202 is arranged at the position where the elastic member 4 abuts the open accommodating cavity, and a second column 304 is arranged in the blind hole 302. The diameters of the first column 202 and the second column are almost equal to the inner diameter of the coil spring, ensuring that one end of the coil spring has an interference fit with the first column 202 and the other end of the coil spring has an interference fit with the second column. This method not only ensures that the elastic member 4 will not shift or fall off during the pressing process, but also facilitates the disassembly and assembly of the parts of the pod quick disassembly and assembly structure.

[0039] like Figure 4 As shown, a section of the pressing member 3 inside the base 1 is also connected to the buckle 5, and the base 1 and the upper cover 6 are combined and separated by the buckle 5. The buckle 5 is mainly composed of a tongue 501, a connecting seat 502 and a vertical plate 503, and the whole presents a "Z"-shaped structure. The tongue 501 and the connecting seat 502 are connected by the vertical plate 503, and the vertical plate 503 is perpendicular to the tongue 501 and the connecting seat 502 respectively. The tongue 501 protrudes outward, and the connecting seat 502 is connected to a section of the pressing member 3 inside the base 1. The connecting seat 502 is connected to the upper surface of the pressing member 3. The surface where the connecting seat 502 is connected to the pressing member 3 is an arc surface, which is completely fitted with the side of the pressing member 3. A first threaded hole 303 is opened on the pressing member 3, and a second threaded hole 504 is opened on the connecting seat 502. The pressing member 3 and the buckle 5 are connected by bolts.

[0040] As a preferred embodiment, a groove opening toward the inner side of the base 1 is provided along the end surface of the connection position between the pressing piece 3 and the buckle 5. At one end of the connecting seat 502 close to the axis of the base 1, a protrusion matching the groove is provided on an arc surface downward. During the installation of the buckle 5 and the pressing piece 3, the buckle 5 and the pressing piece 3 are adjusted so that the protrusion is engaged with the groove to ensure that the first threaded hole 303 is aligned with the second threaded hole 504, thereby facilitating the installation of the buckle 5 and the pressing piece 3.

[0041] Since the pressing member 3 and the buckle 5 are designed as a split type in the embodiment of the utility model, during the installation process, the pressing member 3 carrying the elastic member 4 is pressed into the pressing hole 101, and then the first threaded hole 303 on the buckle 5 is aligned with the second threaded hole 504, and then it is locked by bolts, and the installation process is simple and efficient. In the existing structure of the buckle and the pressing member as an integrated structure, the integrated design requires the pressing member to pass through the pressing hole from the inner side of the base, and the installation process is more difficult. Usually, during the installation process, the elastic member needs to be drastically deformed to complete the installation, which causes greater damage to the elastic member.

[0042] After the pressing member 3, the elastic member 4 and the buckle 5 are installed, the vertical plate 503 of the buckle 5 directly or indirectly rests against the inner wall of the base 1. At this time, the elastic member 4 is in a slightly compressed state. The elastic member 4 provides a certain elastic force to ensure that the pressing member 3 extends out of the pressing hole 101, and the pressing member 3, the elastic member 4 and the buckle 5 will not shake.

[0043] The upper cover 6 is a flat cylindrical cover with the same or similar diameter as the bottom surface of the base 1. A rectangular hole is opened in the center of the upper cover 6. The rectangular hole is used to install the male head 702 of the connector 7, and the installation direction of the male head 702 is downward; a rectangular hole is also opened at the relative position of the support frame 2. The rectangular hole is used to install the female head 701 of the connector 7, and the installation direction of the female head 701 is upward. Connector 7 is a J30 series micro-rectangular electrical connector. Two opening grooves 601 matched with the tongue 501 are also provided at the corresponding positions of the two side edges of the upper cover 6 and the buckle 5. The base 1 and the upper cover 6 are disassembled and assembled by extending or retracting the tongue 501. The opening groove 601 is set at the transition position between the bottom surface and the side surface of the upper cover 6. Below the opening groove 601, the upper cover 6 also has a connected lower plane.

[0044] like Figure 5 and Figure 6 As shown, when the pod needs to be mounted on the drone, the upper cover 6 is connected to the drone, and the male connector 702 is connected to the power grid line inside the drone. By pressing the pressing pieces 3 on both sides of the base 1 with one hand, the pressing pieces 3 move inward along the guide strip 201 and drive the tongue 501 of the buckle 5 to shrink. At this time, the base 1 and the upper cover 6 are combined, and the tongue 501 is aligned with the opening groove 601. Then, the pressing piece 3 is released, and the pressing piece 3 automatically resets under the action of elastic force. The pressing piece 3 drives the tongue 501 to extend from the opening groove 601, and the tongue 501 is against the lower plane connected to the opening groove 601, that is, the pod is quickly mounted on the drone. When the pod needs to be removed from the drone, by pressing the pressing pieces 3 on both sides of the base 1 with one hand, the pressing pieces 3 move inward along the guide strip 201 and drive the tongue 501 of the buckle 5 to shrink, and the tongue 501 is separated from the opening groove 601, that is, the disassembly of the pod is completed.

[0045] Compared with the existing structure, the pod quick disassembly and assembly structure of the embodiment of the utility model greatly improves the convenience and efficiency of structural assembly by installing the pressing member 3 from the outside to the inside; and the structure is simple, occupies little space, and is suitable for one-handed operation.

[0046] Although the embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and cannot be understood as limiting the present invention. A person skilled in the art may change, modify, replace and modify the above embodiments within the scope of the present invention.

[0047] The above specific implementation methods of the utility model do not constitute a limitation on the protection scope of the utility model. Any other corresponding changes and modifications made according to the technical concept of the utility model should be included in the protection scope of the claims of the utility model.
