[0028] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 This embodiment provides a drone fuselage 100, including an upper cover 120, a lower cover 110, and an arm mounting base 130. The lower cover 110 is provided with a first mounting groove 111, and the upper cover 120 is provided with a second mounting groove 121 corresponding to the first mounting groove 111. The first mounting groove 111 and the second mounting groove 121 together form a through hole for the arm mounting base. A lower sealing element 140 is provided on the first mounting groove 111, and an upper sealing element 150 is provided on the second mounting groove 121. The upper sealing element 150 and the lower sealing element 140 together form a sealing ring, which abuts against the outer wall of the arm mounting base 130.
[0029] When assembling the UAV fuselage 100 of this application, the lower seal 140 is first installed in the first mounting groove 111, and the upper seal 150 is installed in the second mounting groove 121. Then, the arm mounting base 130 is installed. The arm mounting base 130 is installed between the upper cover 120 and the lower cover 110 through the arm mounting base through hole, so that the upper seal 150 and the lower seal 140 surround and form a sealing ring that abuts against the outer wall of the arm mounting base 130.
[0030] The drone fuselage 100 provided in this application includes an upper cover 120, a lower cover 110, and an arm mounting base 130. The lower cover 110 has a first mounting groove 111, and the upper cover 120 has a second mounting groove 121 corresponding to the first mounting groove 111. The first mounting groove 111 and the second mounting groove 121 together form a through hole for the arm mounting base. A lower sealing element 140 is provided on the first mounting groove 111, and an upper sealing element 150 is provided on the second mounting groove 121. The upper sealing element 150 and the lower sealing element 140 together form a sealing ring, which abuts against the outer wall of the arm mounting base 130. By providing the upper sealing element 150 and the lower sealing element 140 on the mounting grooves of the upper cover 120 and the lower cover 110 respectively, the sealing ring formed by the two elements tightly abuts against the outer wall of the arm mounting base 130, effectively preventing rainwater from entering the fuselage from the connection point between the fuselage and the arm mounting base 130. This significantly reduces the risk of rainwater damage to internal electronic components, ensuring the drone's normal operation in adverse weather conditions (such as rain), and substantially improving the safety and reliability of drone flight. The first mounting slot 111 is located on the lower cover 110, and the second mounting slot 121 is located on the upper cover 120. Together, they form a through-hole design for the arm mounting bracket 130, facilitating installation and achieving a good seal through the sealing element. This structural design ensures a tight and rational connection between the various parts of the fuselage, contributing to improved overall stability and durability.
[0031] In one possible embodiment of this application, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the upper seal 150 has a first groove 151, the lower seal 140 has a second groove 141, and the outer wall of the arm mounting base 130 has an annular protrusion 131, which engages with the first groove 151 and the second groove 141 respectively. When the arm mounting base 130 passes through the sealing ring formed by the upper seal 150 and the lower seal 140, the annular protrusion 131 engages with the first groove 151 and the second groove 141 respectively. This engagement further enhances the sealing effect, better preventing rainwater from entering the fuselage and improving the waterproof performance of the UAV fuselage 100.
[0032] In one possible embodiment of this application, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a lower cover silicone 160 is provided on the outer edge of the lower cover 110, and the lower cover silicone 160 abuts against the upper cover 120. When the lower cover 110 and the upper cover 120 are assembled together, the lower cover silicone 160 plays a sealing role, preventing rainwater from entering the fuselage from the connection between the upper cover 120 and the lower cover 110, further improving the overall waterproof performance of the drone fuselage 100.
[0033] Furthermore, the first mounting groove 111 has a first snap-fit portion, through which the lower seal 140 is snapped. The first mounting groove 111 has a first snap-fit portion, through which the lower seal 140 is snapped, and this snap-fit method allows the lower seal 140 to be securely installed in the first mounting groove 111, ensuring the positional accuracy and stability of the lower seal 140, thereby ensuring its sealing effect.
[0034] Furthermore, the second mounting groove 121 has a second snap-fit portion, through which the upper seal 150 is snapped. Similarly, this snap-fit method ensures that the upper seal 150 is securely installed within the second mounting groove 121, guaranteeing the positional accuracy and stability of the upper seal 150, thereby ensuring the sealing effect of the entire sealing ring.
[0035] Furthermore, the arm mounting base 130 includes a mounting section 132 and an extension section 133. The mounting section 132 is installed within the cavity formed by the upper cover 120 and the lower cover 110, and the extension section 133 extends out of the cavity. This structural design ensures a stable connection between the arm mounting base 130 and the fuselage, while also allowing the arm to be installed outside the fuselage via the extension section 133, facilitating the installation and layout of the UAV arm.
[0036] Furthermore, the lower cover 110 has a boss along its outer edge, and the upper cover 120 has a corresponding recess along its outer edge, with the boss and recess engaging in a snap-fit connection. This snap-fit connection not only serves a positioning function, allowing the upper cover 120 and the lower cover 110 to be accurately assembled, but also enhances the tightness of the connection between the upper cover 120 and the lower cover 110 to a certain extent, reducing the possibility of rainwater entering the fuselage from the connection point.
[0037] Furthermore, the lower cover 110 is provided with positioning posts, and the upper cover 120 is provided with positioning grooves corresponding to the positioning posts. The positioning posts can be inserted and engaged with the positioning grooves. Through the insertion and engagement of the positioning posts and positioning grooves, the upper cover 120 and the lower cover 110 can be positioned more accurately, ensuring that the first mounting groove 111 and the second mounting groove 121 can be accurately aligned. This also helps to improve the efficiency of assembling the upper cover 120 and the lower cover 110.
[0038] Furthermore, the lower cover 110 is provided with mounting holes, and the upper cover 120 is provided with fixing holes corresponding to the mounting holes. Fasteners are used to connect the lower cover 110 and the upper cover 120 through the mounting holes and fixing holes. This fixing method allows the upper cover 120 and the lower cover 110 to be firmly connected together, ensuring the stability of the machine body structure, and also facilitating disassembly and maintenance when needed.
[0039] When assembling the UAV fuselage 100 of this application, first confirm the position of the first snap-fit portion on the first mounting groove 111. Align the lower seal 140 with the first mounting groove 111, ensuring the edge of the lower seal 140 is accurately aligned with the first snap-fit portion. Then, press the lower seal 140 into the first mounting groove 111, securing it firmly within the groove using the first snap-fit portion. During pressing, ensure the lower seal 140 is completely fitted into the first mounting groove 111 without any lifting or twisting. Align the upper seal 150 with the second mounting groove 121, ensuring the edge of the upper seal 150 matches the second snap-fit portion. Next, press the upper seal 150 into the second mounting groove 121, securing it firmly within the groove using the second snap-fit portion. Again, ensure the upper seal 150 is installed flat within the second mounting groove 121 without any abnormal deformation.
[0040] Next, install the boom mount 130. The mounting section 132 is for installation inside the machine body, and the annular protrusion 131 is a structure used to enhance the sealing effect. Align the mounting section 132 of the boom mount 130 with the boom mount through hole formed by the first mounting groove 111 of the lower cover 110 and the second mounting groove 121 of the upper cover 120. During the alignment process, pay attention to the positional relationship between the annular protrusion 131 of the boom mount 130 and the first groove 151 of the upper seal 150 and the second groove 141 of the lower seal 140.
[0041] The boom mounting base 130 is passed through the through hole in the boom mounting base, so that the annular protrusion 131 is respectively engaged in the first groove 151 and the second groove 141. During this process, it is important to ensure a tight engagement, and at the same time, feel the sealing ring formed by the upper seal 150 and the lower seal 140 tightly abutting against the outer wall of the boom mounting base 130, which provides an initial sealing effect. At this time, the mounting section 132 of the boom mounting base 130 is located in the cavity formed by the upper cover 120 and the lower cover 110, and the extension section 133 extends out of the cavity.
[0042] Next, align the upper cover 120 and the lower cover 110. Pick up the upper cover 120 and observe the position of the protrusions, positioning posts, and silicone 160 on the outer edge of the lower cover 110. Simultaneously, check the corresponding recesses and positioning grooves on the outer edge of the upper cover 120. Slowly bring the upper cover 120 closer to the lower cover 110, first aligning the protrusions on the outer edge of the lower cover 110 with the recesses on the outer edge of the upper cover 120 for initial positioning and alignment. During alignment, ensure that the protrusions smoothly engage with the recesses and that the two fit tightly together.
[0043] Next, insert the positioning pin on the lower cover 110 into the positioning groove of the upper cover 120. The cooperation between the positioning pin and the positioning groove can further accurately determine the relative position of the upper cover 120 and the lower cover 110, ensuring that the upper cover 120 and the lower cover 110 are accurately aligned. At this time, the silicone 160 of the lower cover tightly abuts against the upper cover 120, providing further protection for the overall sealing of the machine body. Check the mounting holes on the lower cover 110 and the corresponding fixing holes on the upper cover 120. The mounting holes and fixing holes are positioned to correspond to each other and are used to insert fasteners to fix the upper cover 120 and the lower cover 110. Depending on the type of fastener selected (such as screws), use the appropriate tool (such as a screwdriver) to pass the fastener through the mounting holes of the lower cover 110 and the fixing holes of the upper cover 120.
[0044] This application also discloses a drone, including a control module, a propeller, and the drone fuselage 100 as described in the foregoing embodiments. The control module is disposed within the cavity formed by the upper cover 120 and the lower cover 110, and the propeller is disposed on the arm mounting base 130. This drone has the same structure and beneficial effects as the drone fuselage 100 in the foregoing embodiments. The structure and beneficial effects of the drone fuselage 100 have been described in detail in the foregoing embodiments and will not be repeated here.
[0045] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
