Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and specifically to a UAV that is easy to maintain. Background Technology

[0002] With the continuous development of science and technology, drone technology has greatly improved in recent years, and many intelligent and multifunctional unmanned aerial vehicles have emerged. In response to the needs of transmitting information and monitoring in some small areas, unmanned aerial vehicles are receiving more and more attention. It is a new concept aircraft that is developing rapidly. It has the advantages of being maneuverable, quick to respond, unmanned, and having low operation requirements.

[0003] In practical applications, drones have landing gear at the bottom of their fuselage to support the fuselage and prevent it from directly contacting the ground. This prevents the ground from directly contacting the drone and causing wear and tear. At the same time, the landing gear is an important component that ensures the stability of the drone's takeoff and safe landing.

[0004] Because the landing gear of a drone is in direct contact with the ground before takeoff or landing, and the landing process generates a certain impact force, the drone landing gear is prone to wear or damage and needs to be replaced. However, the landing gear of existing drones is generally integrated with the fuselage frame. Although it can support the drone and help it takeoff or landing, the fixed connection makes it difficult for operators to quickly disassemble or install worn or damaged landing gear, thus hindering the rapid replacement and maintenance of the landing gear. Utility Model Content

[0005] The purpose of this invention is to provide a drone that is easy to maintain, solving the problem that the fixed landing gear of existing drones is not easy to disassemble and assemble, making it difficult for operators to quickly disassemble or assemble worn or damaged landing gear, thus making it impossible to quickly replace and maintain the landing gear.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] An easy-to-maintain drone includes a drone body and a mounting base located at the bottom of the drone body. The mounting base has fixed seats on both the left and right sides of its front end, and horizontally arranged grooves on both the left and right sides of its rear end. A sliding rod is fixed within the groove, and a slider slides within the groove, slidingly fitted onto the outside of the sliding rod. The end of the slider away from the groove extends out of the groove and is connected to a sliding seat. A support spring is fitted onto the sliding rod, with one end connected to the side of the slider away from the fixed seat and the other end connected to the groove wall. The fixed seats and sliding seats each have opposing fixing holes and connecting holes. A fixing rod and a connecting rod are inserted into the fixing holes and connecting holes respectively, and the opposing ends of the fixing rod and connecting rod are connected to the same landing gear.

[0008] A further technical solution is to provide a limiting groove along the axis of the inner wall of the fixing hole, and to provide a limiting strip that matches the limiting groove on the outer wall of the fixing rod.

[0009] A further technical solution is that a fixing magnet and a connecting magnet are respectively fixed in the ends of the fixing hole and the connecting hole that are far apart from each other, and a fixing magnetic block and a connecting magnetic block are respectively embedded in the ends of the fixing rod and the connecting rod that are far apart from each other.

[0010] A further technical solution is to provide a toggle block protruding on the side of the sliding seat away from the mounting seat.

[0011] A further technical solution is that the landing gear includes a support rod and a crossbar. The top of the support rod is fixedly connected to the opposite end of the fixed rod and the connecting rod. Its bottom end is inclined downward and connected to the middle of the horizontally set crossbar. Both ends of the crossbar are provided with mounting ring grooves around its outer side. The bottom of the annular groove of the mounting ring groove is uniformly provided with limiting protrusions. A silicone ring with an outer ring diameter larger than the outer ring diameter of the crossbar is detachably fitted inside the mounting ring groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] When the landing gear needs to be installed, push the sliding block along the slide groove away from the fixed seat. When the distance between the sliding block and the fixed seat increases to a suitable level, insert the fixing rod into the fixing hole, release the sliding block, and the supporting spring will cause the sliding block to move closer to the fixed seat, so that the connecting rod is inserted into the connecting hole, thereby achieving quick installation of the landing gear. When the landing gear needs to be disassembled for maintenance, simply slide the sliding block along the slide groove away from the fixed seat, so that the connecting rod slides out of the connecting hole. Then continue to push the sliding block away from the fixed seat until the distance between the sliding block and the fixed seat is sufficient to allow the fixing rod to slide out of the fixing hole. Then slide the fixing rod out of the fixing hole to remove the landing gear. Attached Figure Description

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] Example 1

[0021] See Figures 1 to 4 The present invention discloses a maintenance-friendly unmanned aerial vehicle (UAV), comprising a UAV body 1 and a mounting base 2 located at the bottom of the UAV body 1. The mounting base 2 has fixed seats 3 on both the left and right sides of its front end, and horizontally arranged sliding grooves 4 on both the left and right sides of its rear end. A sliding rod 5 is fixedly installed within the sliding groove 4, and a slider 6 is slidably installed within the sliding groove 4, with the slider 6 slidably sleeved on the outside of the sliding rod 5. One end of the slider 6, away from the sliding groove 4, extends out of the sliding groove 4 and is connected to a sliding seat 7. A support spring 8 is sleeved on the sliding rod 5, with one end connected to the side of the slider 6 away from the fixed seat 3 and the other end connected to the groove wall of the sliding groove 4. The fixed seat 3 and the sliding seat 7 each have opposing fixed holes 9 and connecting holes 10. A fixed rod 11 and a connecting rod 12 are respectively inserted into the fixed holes 9 and the connecting holes 10. The opposing ends of the fixed rod 11 and the connecting rod 12 are connected to the same landing gear 13.

[0022] When this solution is in use, if the landing gear 13 needs to be installed, push the sliding seat 7 to slide along the slide groove 4 away from the fixed seat 3. At this time, the slider 6 slides along the slide rod 5 away from the fixed seat 3 and compresses the support spring 8. When the distance between the sliding seat 7 and the fixed seat 3 increases to a suitable distance, insert the fixed rod 11 into the fixed hole 9, release the sliding seat 7, and under the action of the support spring 8, push the slider 6 to move along the slide rod 5 closer to the fixed seat 3, causing the sliding seat 7 to move closer to the fixed seat 3. When the sliding seat 7 approaches the connecting rod 12, the connecting rod 12 and the connecting hole 10 are aligned. The connecting rod 12 is inserted into the connecting hole 10, thereby enabling the quick installation of the landing gear 13 to support the UAV body 1. When the landing gear 13 needs to be disassembled for maintenance, simply slide the sliding seat 7 along the slide groove 4 away from the fixed seat 3, so that the connecting rod 12 slides out of the connecting hole 10. Then continue to push the sliding seat 7 away from the fixed seat 3 until the distance between the sliding seat 7 and the fixed seat 3 is sufficient to allow the fixed rod 11 to slide out of the fixed hole 9. Then slide the fixed rod 11 out of the fixed hole 9 to remove the landing gear 13.

[0023] As a preferred implementation method, see [link / reference] Figures 1 to 4 As shown, a limiting groove 14 is formed on the inner wall of the fixing hole 9 along its axis, and a limiting strip 15 that is adapted to the limiting groove 14 is provided on the outer wall of the fixing rod 11. By setting the limiting groove 14 and the limiting strip 15, when the fixing rod 11 is inserted into the fixing hole 9, the limiting groove 14 and the limiting strip 15 cooperate to limit the fixing rod 11, prevent the fixing rod 11 from rotating in the fixing hole 9, avoid the connecting rod 12 from rotating in the connecting hole 10, and ensure the stability of the landing gear 13 installation.

[0024] Example 2

[0025] Based on the foregoing embodiments, see [link to previous document]. Figures 1 to 4 As shown, a fixed magnet 16 and a connecting magnet 17 are fixedly installed in the ends of the fixed hole 9 and the connecting hole 10 that are far apart from each other. A fixed magnetic block 18 and a connecting magnetic block 19 are embedded in the ends of the fixed rod 11 and the connecting rod 12 that are far apart from each other. By setting the fixed magnet 16 and the connecting magnet 17, when the fixed rod 11 and the connecting rod 12 are respectively inserted into the fixed hole 9 and the connecting hole 10, the fixed magnet 16 and the fixed magnetic block 18 attract each other, and the connecting magnet 17 and the connecting magnetic block 19 attract each other. Under the limiting action of the supporting spring 8 on the sliding seat 7, the limiting effect on the sliding seat 7 is further improved, preventing the sliding seat 7 from moving away from the fixed seat 3 along the slide groove 4, and ensuring the stability of the landing gear 13 connection.

[0026] As a preferred implementation method, see [link / reference] Figure 1As shown, a toggle block 20 protrudes from the side of the sliding seat 7 away from the mounting seat 2. By setting the toggle block 20, it is easy to push the sliding seat 7 to move.

[0027] Example 3

[0028] Based on the foregoing embodiments, see [link to previous document]. Figures 1 to 4 As shown, the landing gear 13 includes a support rod 21 and a crossbar 22. The top of the support rod 21 is fixedly connected to the opposite end of the fixed rod 11 and the connecting rod 12, and its bottom end is inclined downward and connected to the middle of the horizontally arranged crossbar 22. Both ends of the crossbar 22 are provided with mounting ring grooves 23 around its outer side. Multiple limiting protrusions 24 are evenly protruding from the bottom of the annular groove of the mounting ring groove 23. A silicone ring 25 with an outer ring diameter larger than that of the crossbar 22 is detachably fitted inside the mounting ring groove 23. During use, by setting the silicone ring 25, the crossbar 22 can be prevented from directly contacting the ground and causing wear. The silicone ring 25 has an anti-slip function, ensuring stability when in contact with the ground. The mounting groove 23 limits the silicone ring 25, preventing it from sliding out of the end of the crossbar 22. The limiting protrusion 24 further limits the silicone ring 25, preventing it from rotating within the mounting groove 23. It should be noted that the inner diameter of the silicone ring 25 can be set smaller than the diameter of the bottom of the annular groove 23 to ensure the stability of the silicone ring 25 within the mounting groove 23. The silicone ring 25 is also detachable from the mounting groove 23, facilitating future replacement.

[0029] Although the present invention has been described herein with reference to several illustrative embodiments, it should be understood that many other modifications and implementations can be devised by those skilled in the art, which will fall within the scope and spirit of the principles disclosed herein. More specifically, various variations and modifications can be made to the components and / or layout of the subject matter combination within the scope of the disclosure, drawings, and claims. Besides variations and modifications to the components and / or layout, other uses will be apparent to those skilled in the art.
