Detailed implementation manners

[0025] The following describes in detail a quick-disassembly and assembly type connection component and a UAV provided by the present invention in conjunction with the accompanying drawings and specific embodiments. At the same time, it should be noted here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments. For some well-known technologies, those skilled in the art can also adopt other alternative methods for implementation; moreover, the drawings are only for more specifically describing the embodiments and are not intended to specifically limit the present invention.

[0026] As Figure 1 - Figure 4 As shown, an embodiment of the present invention provides a quick-disassembly and assembly type connection component, including: a mounting seat 5, having a rectangular structure, and an inner cavity with two-way communication is provided inside the mounting seat 5; a mounting block 4, having a U-shaped structure, one side of the mounting block 4 is slidably matched with the inner cavity of the mounting seat 5, and the other side of the mounting block 4 is fixedly connected with two parallel landing gears 2 through a support rod 3; a limiting component 6, arranged on the end wall of the mounting block 4, for the sliding between the mounting block 4 and the mounting seat 5 to ensure the stability of the connection; a UAV, including a UAV body 1 and the above-mentioned quick-disassembly and assembly type connection component; the mounting seat 5 is fixedly connected to the bottom of the UAV body 1.

[0027] By setting a slider structure and cooperating with the limiting component 6 to realize the installation of the UAV landing gear 2, it replaces the installation method of traditional fasteners such as bolts, and the installation and disassembly between the UAV and the landing gear 2 can be completed without using any tools, improving the replacement efficiency of the UAV landing gear 2.

[0028] As Figure 3 shown, it further includes a limit block 41, arranged on the mounting block 4, and the limit block 41 protrudes from the side wall of the mounting block 4, and the purpose is to abut against the end wall of the mounting seat 5 when the mounting block 4 and the mounting seat 5 are connected in cooperation.

[0029] Among them, the mounting block 4 is provided with a notch in the middle position of the bottom area in the working state. Through this setting, not only are the accessory consumables saved and the weight of the drone reduced, but when the mounting block 4 is inserted into the mounting seat 5, the sliding distance of the mounting block 4 is positioned by the abutment of the limiting block 41 against the end wall of the mounting seat 5, thereby balancing the weight of the arc portion of the mounting block 4 and enabling the two sides of the drone to be balanced in force after the landing gear 2 is installed.

[0030] As Figure 1 shown, it further includes a slide rail 42, which is arranged at the position of the end wall on one side where the mounting block 4 and the mounting seat 5 are slidably matched and does not protrude from the axial side wall of the mounting block 4. Two symmetrically arranged through grooves 43 are opened on the outer side of the slide rail 42.

[0031] The slide rail 42 is closely attached to the side wall of the mounting block 4, providing a smooth track for the sliding of the mounting block 4 on the mounting seat 5 and reducing friction and wear. At the same time, the two symmetric through grooves 43 opened on the outer side of the slide rail 42 provide an installation space and an operation path for the subsequent limiting component 6. This design enables the limiting component 6 to flexibly perform telescopic and locking operations inside the slide rail 42 without affecting the overall sliding performance of the mounting block 4.

[0032] As Figure 4 shown, the limiting component 6 includes: a fixed block 61, fixed at the central position inside the slide rail 42; two guide rods 62, which are arranged collinearly at the central positions at both ends of the fixed block 61; a locking block 64, which is slidably connected with the inner side wall of the slide rail 42 and is set to protrude from the end wall of the through groove 43 and abut against the end wall of the mounting seat 5 under normal conditions; a dial block 67, which is fixedly connected to the locking block 64 through a connecting block 66, and the connecting block 66 is slidably connected with the through groove 43.

[0033] Among them, the fixed block 61 serves as the basic support structure of the limiting component 6. The fixed block 61 is firmly installed at the central position inside the slide rail 42, providing a stable installation platform for other components; the two collinearly arranged guide rods 62 not only provide precise guidance for the sliding of the locking block 64; the dial block 67 is fixedly connected to the locking block 64 through the connecting block 66, and the user can indirectly control the sliding of the locking block 64 by operating the dial block 67.

[0034] As Figure 4 shown, a chute 65 is opened on the locking block 64 for slidably connecting with the guide rod 62.

[0035] Through the cooperation of the chute 65 on the locking block 64 and the guide rod 62, the stability and accuracy of the locking block 64 during the sliding process are ensured.

[0036] As Figure 4As shown, two locking blocks 64 are provided and symmetrically slidably connected at both ends of the slide rail 42, thereby ensuring the stability of the sliding connection limit of the mounting block 4 and the mounting seat 5. Furthermore, one end of the locking block 64 used to abut against the end wall of the mounting seat 5 is provided with a chamfered surface to reduce its sliding friction resistance in the inner cavity of the mounting seat 5.

[0037] like Figure 4 As shown, a spring 63 is also included, which is sleeved on the rod body of the guide rod 62, and two ends of the spring 63 are respectively in contact with the fixing block 61 and the locking block 64.

[0038] When the locking block 64 is driven by the shifting block 67 to slide outward, the spring 63 is compressed to store energy; once the shifting block 67 is released, the elastic force of the spring 63 will push the locking block 64 to automatically reset and re-engage with the end wall of the mounting seat 5 to achieve rapid locking.

[0039] The technical solution provided by the utility model is that when installing the landing gear of the UAV, the slide rail 42 of the mounting block 4 is aligned with the inner cavity of the mounting seat 5 and gently pushed in. During the sliding process, due to the inclined chamfer set at the end of the locking block 64, it abuts and slides, and the counter-spring 63 pushes the locking block 64 into the slide rail 42, so that the limit block 41 of the mounting block 4 is initially abutted against the end wall of the mounting seat 5, and the mounting block 4 continues to slide along the slide rail 42 until the limit block 41 passes through the inner cavity of the mounting seat 5 and automatically pops out under the elastic force of the spring 63. When the mounting block 4 is in full contact with the end wall of the mounting seat 5, the limit block 41 is in contact with the other end of the mounting seat 5. At this time, the weight of the arc-shaped portion of the mounting block 4 is balanced, ensuring that the force on both sides of the UAV is even, thereby completing the installation of the landing gear. When disassembling, the fingers are pressed against the two ends of the two shift blocks 67 and force is applied inward, so that the locking block 64 is retracted to the inside of the slide rail 42 against the elastic force of the spring 63. At this time, the mounting block 4 loses the contact between the locking block 64 and the end wall of the mounting seat 5, so that the mounting block 4 can slide out of the inner cavity of the mounting seat 5, completing the disassembly of the landing gear.

[0040] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the above preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0041] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
