Description

Technical Field

[0001] This application relates to the field of drone components, and more particularly to an inspection device for drones and the drone thereof. Background Technology

[0002] A drone is an unmanned aircraft controlled by radio remote control equipment and its own program control device. The drone has an inspection port on its fuselage, equipped with inspection devices to facilitate inspection.

[0003] In related technologies, the inspection device includes a mounting base and a cover plate. The mounting base is fixedly connected to the inspection port of the fuselage and has an inspection hole that communicates with the interior of the fuselage. The cover plate is fixedly connected to the mounting base by bolts. By removing the bolts and opening the cover plate, the drone can be inspected.

[0004] However, after the drone inspection is completed, the cover plate bolts need to be re-tightened to secure it, which is a rather cumbersome operation and therefore needs to be improved. Summary of the Invention

[0005] To facilitate the fixing of the cover plate, in a first aspect, this application provides an inspection device for unmanned aerial vehicles.

[0006] The inspection device for unmanned aerial vehicles provided in this application adopts the following technical solution:

[0007] An inspection device for a drone includes a mounting base, a cover plate, and a connecting assembly; the cover plate is rotatably connected to the mounting base; the connecting assembly includes a connecting seat, two rotating arms, a torsion spring, and a latch; the connecting seat is disposed in the mounting base; one end of each of the two rotating arms is rotatably connected to the connecting seat, the torsion spring is disposed in the two rotating arms to drive the other ends of the two rotating arms to rotate toward a side that is close to each other, and a groove is formed between the two rotating arms; the latch is disposed on the side of the cover plate near the mounting base and engages in the groove.

[0008] By adopting the above technical solution, after the UAV inspection is completed, the cover plate is rotated so that the buckle passes between the two rotating arms. Under the squeezing action of the buckle, the two rotating arms rotate toward the side that is far away from each other and the torsion spring is elastically deformed. After the buckle passes through the two rotating arms, the torsion spring resets to drive the two rotating arms to rotate toward the side that is close to each other, so that a groove is formed between the two rotating arms. At this time, the buckle is engaged in the groove to fix the cover plate. The operation is simple and convenient.

[0009] Preferably, the connecting assembly further includes two rollers, which are respectively disposed on the two rotating arms, and each roller is rotatably connected to the end of each rotating arm away from its own rotation.

[0010] By adopting the above technical solution, and by setting two rollers, when the buckle passes between the two rotating arms, the buckle contacts the two rollers, causing the two rollers to rotate, thereby reducing the friction between the buckle and the two rotating arms, thus making it easier for the buckle to engage in the slot.

[0011] Preferably, the inspection device further includes two rotating components, which are respectively disposed at both ends of the cover plate; each rotating component includes a rotating sleeve, a rotating plate, and a fastener, the rotating sleeve is disposed on the mounting base, the rotating plate is rotatably connected to the rotating sleeve and fits against the side of the cover plate near the mounting base, and one end of the fastener is movably inserted through the cover plate and threaded onto the rotating plate.

[0012] By adopting the above technical solution and setting a rotating component, the cover plate can be rotatably connected to the mounting base, which facilitates the installation between the cover plate and the mounting base.

[0013] Preferably, the cover plate has a countersunk hole on the side away from the mounting base, and the fastener is embedded in the countersunk hole at the end away from the rotating piece.

[0014] By adopting the above technical solution and setting countersunk holes, fasteners are prevented from protruding from the cover plate as much as possible, thereby reducing the drag of the drone during flight.

[0015] Preferably, the inspection device further includes a limiting component and a pressing component; the limiting component includes a limiting rod and a first elastic element, the limiting rod being slidably connected to one of the rotating arms and being driven away from the other rotating arm by the first elastic element; the buckle has a limiting hole, and the pressing component is used to press the limiting rod so that the limiting rod is inserted into the limiting hole.

[0016] By adopting the above technical solution, by setting a limiting component and a pressing component, the limiting rod is slidably connected to one of the rotating arms, and driven by the first elastic element, it moves away from the other rotating arm, so that the buckle can be engaged in the slot. The pressing component presses the limiting rod so that the limiting rod is inserted into the limiting hole, further limiting the buckle and the two rotating arms, thereby improving the stability of the buckle engagement.

[0017] Preferably, the clamping assembly includes a mounting cylinder, a clamping rod, and a second elastic element; the mounting cylinder is located on the side of the cover plate near the mounting base, and the inner side of the mounting cylinder has a sliding groove along its length and a rotating groove along its circumference, the rotating groove being located at the end of the sliding groove away from the cover plate, and the cover plate having a connecting hole communicating with the interior of the mounting cylinder; the clamping rod includes a clamping part, a limiting part, and a rotating part; the clamping part is movably inserted through the mounting cylinder, and one end of the clamping part abuts against the limiting rod; the limiting part is located on the clamping part and limited to the rotating groove; the rotating part is located at the end of the clamping part away from the limiting rod and at the connecting hole; the second elastic element is located between the mounting cylinder and the limiting part to drive the clamping part away from the limiting rod.

[0018] By adopting the above technical solution, and by setting an installation cylinder, a clamping rod, and a second elastic element, when the buckle is engaged in the slot, pressing the rotating part causes the limiting part to slide along the sliding groove toward the end closer to the rotating groove, so that the clamping part is close to the limiting rod. At this time, the end of the clamping part abuts against the limiting rod to achieve clamping of the limiting rod, and the rotating part is located in the connecting hole. By rotating the rotating part, the limiting part is limited to the rotating groove, and under the action of the second elastic element, the clamping part is stably kept in the clamping state of the limiting rod.

[0019] Preferably, the end of the limiting rod near the pressing part is provided with a guide groove.

[0020] By adopting the above technical solution and setting a guide groove, as the pressing part approaches the limiting rod, the pressing part abuts against the groove wall of the guide groove, so as to automatically drive the limiting rod to move toward the end close to the buckle, so that the limiting rod can be inserted into the limiting hole.

[0021] Preferably, the mounting cylinder has a limiting groove at one end of the rotating groove away from the sliding groove and facing the other end of the sliding groove.

[0022] By adopting the above technical solution and setting a limiting groove, when the limiting part is limited to the end of the limiting groove away from the sliding groove, the second elastic element drives the pressing part to move so that the limiting part is limited in the limiting groove, thereby avoiding the rotation of the rotating part as much as possible, so as to show that the limiting part is disengaged from the rotating groove, thereby improving the stability of the pressing part pressing the limiting rod.

[0023] Preferably, the clamping assembly further includes an elastic pad, which is disposed at one end of the mounting cylinder near the cover plate and abuts against the rotating part.

[0024] By adopting the above technical solution and setting an elastic pad, the movement of the rotating part can be restricted by the elastic pad against the rotating part, thereby minimizing the risk of the limiting part leaving the limiting groove.

[0025] Secondly, this application provides a drone.

[0026] The UAV provided in this application adopts the following technical solution:

[0027] A drone including the inspection device described above.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. By rotating the cover plate, the buckle passes between the two rotating arms. Under the squeezing action of the buckle, the two rotating arms rotate toward the side away from each other and the torsion spring is elastically deformed. After the buckle passes through the two rotating arms, the torsion spring returns to its original position, so as to drive the two rotating arms to rotate toward the side closer to each other, so that a groove is formed between the two rotating arms. At this time, the buckle is engaged in the groove to fix the cover plate. The operation is simple and convenient.

[0030] 2. By setting a limiting component and a pressing component, the limiting rod is slidably connected to one of the rotating arms and moved away from the other rotating arm under the drive of the first elastic element, so that the buckle can be engaged in the slot. The limiting rod is pressed by the pressing component so that the limiting rod is inserted into the limiting hole, further limiting the buckle and the two rotating arms to improve the stability of the buckle engagement.

[0031] 3. By setting up an installation cylinder, a clamping rod, and a second elastic element, when the buckle is engaged in the slot, pressing the rotating part causes the limiting part to slide in the sliding groove near the end of the rotating groove, so that the clamping part is close to the limiting rod. At this time, the end of the clamping part abuts against the limiting rod to achieve clamping of the limiting rod. The rotating part is located in the connecting hole. By rotating the rotating part, the limiting part is limited to the rotating groove. Under the action of the second elastic element, the clamping part is stably kept in the clamping state of the limiting rod. Attached Figure Description

[0040] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0041] This application discloses an inspection device for unmanned aerial vehicles (UAVs).

[0042] Example 1:

[0043] Reference Figure 1 The inspection device includes a mounting base 1, a cover plate 2, and a connecting assembly 3. A rectangular mounting groove 11 is provided on the upper side of the mounting base 1. Two inspection holes 12 communicating with the inside of the UAV are provided on the bottom wall of the mounting groove 11. One side of the cover plate 2 is rotatably connected to the mounting base 1.

[0044] Reference Figure 1 and Figure 2The connecting assembly 3 includes a connecting seat 31, two rotating arms 32, a torsion spring 33, and a buckle 34. The connecting seat 31 is fixedly connected to the side wall of the mounting groove 11 away from the rotating side of the cover plate 2, and the connecting seat 31 is hollow with an opening at the top. The two rotating arms 32 are arranged opposite each other, with one end of each rotating arm 32 rotatably connected to the connecting seat 31. The torsion spring 33 is located in the connecting seat 31 and is connected to one rotating end of each of the two rotating arms 32, driving the other ends of the two rotating arms 32 to rotate toward the side that is closer to each other, so that a groove 35 is formed between the two rotating arms 32. The buckle 34 is fixedly connected to the side of the cover plate 2 near the mounting seat 1, and the shape of the buckle 34 is adapted to the groove 35 and engages in the groove 35 to fix the cover plate 2. It should be noted that at this time, the cover plate 2 is flush with the upper side of the mounting seat 1 to ensure a smooth transition of the UAV surface as much as possible to reduce drag during flight.

[0045] In practical applications, after the drone inspection is completed, the staff rotates the cover plate 2, causing the buckle 34 to pass through the two rotating arms 32. The buckle 34 presses the ends of the two rotating arms 32 away from the rotating end, causing the two rotating arms 32 to rotate towards the opposite side. Under the pressure, the torsion spring 33 undergoes elastic deformation. After the buckle 34 passes through the ends of the two rotating arms 32, under the action of the torsion spring 33, the two rotating arms 32 are driven to reset and re-form the slot 35. At this time, the two rotating arms 32 abut against the buckle 34, so that the buckle 34 is engaged in the slot 35, thereby fixing the cover plate 2. The operation is simple and convenient, making it easy to fix the cover plate 2. Similarly, the cover plate 2 can be pried open with a tool to disengage the buckle 34 from the slot 35, and then the cover plate 2 can be rotated to disassemble and open the cover plate 2. The operation is also relatively simple and convenient.

[0046] In some embodiments, the connecting assembly 3 further includes two rollers 36, which are correspondingly disposed on two rotating arms 32. Each roller 36 is rotatably connected to the end of the rotating arm 32 away from its own rotation and protrudes from the rotating arm 32, such that the two rollers 36 abut against the latch 34, thereby enabling the rotating arm 32 to abut against the latch 34. When the latch 34 passes between the two rotating arms 32, it contacts the two rollers 36, causing the two rollers 36 to rotate. This reduces the friction between the latch 34 and the rotating arm 32, facilitating the latch 34 to pass through the two rotating arms 32 and thus easily engage in the latch groove 35, further facilitating the fixing of the cover plate 2.

[0047] Reference Figure 3 and Figure 4In some embodiments, the inspection device further includes two rotating components 4, which are respectively located at both ends of the rotating side of the cover plate 2. Specifically, the rotating component 4 includes a rotating sleeve 41, a rotating plate 42, and a fastener 43. One end of the rotating sleeve 41 is fixedly connected to the mounting base 1, one end of the rotating plate 42 is rotatably connected to the rotating sleeve 41, and the other end is attached to the side of the cover plate 2 located at the buckle 34. The fastener 43 is a bolt, one end of which passes through the cover plate 2 and is threadedly connected to the rotating plate 42 to fix the cover plate 2 and the rotating plate 42, thereby realizing the rotatable connection of the cover plate 2 to the mounting base 1. In this embodiment, a nut 44 is welded onto the rotating plate 42, and the fastener 43 is threadedly connected to the nut 44. During the installation of the cover plate 2, the rotating sleeve 41 is first fixedly connected to the mounting base 1, and then the fastener 43 is threadedly connected to the rotating plate 42, thereby realizing the rotatable connection of the cover plate 2 to the mounting base 1, which facilitates the installation and removal of the cover plate 2 from the mounting base 1, and facilitates the assembly of the inspection device.

[0048] Reference Figure 4 In some embodiments, a countersunk hole 21 is provided on the side of the cover plate 2 away from the mounting base 1, and the end of the fastener 43 away from the rotating piece 42 is embedded in the countersunk hole 21 so that the end of the fastener 43 is flush with the cover plate 2, so as to avoid the fastener 43 protruding from the cover plate 2 as much as possible, thereby improving the surface smoothness of the UAV and reducing the drag during flight.

[0049] The implementation principle of this embodiment is as follows: In practical application, after the drone inspection is completed, the staff rotates the cover plate 2, so that the buckle 34 passes through the two rotating arms 32. The buckle 34 presses the end of the two rotating arms 32 away from the rotating end, so that the two rotating arms 32 rotate towards the side away from each other. Under the pressure, the torsion spring 33 undergoes elastic deformation. After the buckle 34 passes through the end of the two rotating arms 32, under the action of the torsion spring 33, the two rotating arms 32 are driven to reset and re-form the slot 35. At this time, the two rotating arms 32 abut against the buckle 34 so that the buckle 34 is engaged in the slot 35, thereby fixing the cover plate 2. The operation is simple and convenient, so as to fix the cover plate 2. Similarly, the buckle 34 can be disengaged from the slot 35 by prying open the cover plate 2 with a tool, and then the cover plate 2 can be rotated to disassemble and open the cover plate 2. The operation is also relatively simple and convenient.

[0050] Example 2:

[0051] Reference Figure 5This embodiment is identical to Embodiment 1 in all other structural aspects, except that the inspection device further includes a limiting component 5 and a clamping component 6. The limiting component 5 includes a limiting rod 51 and a first elastic element 52. The limiting rod 51 slides along the length of the mounting groove 11, connecting the mounting base 1 to one of the rotating arms 32, and remains within the rotating arm 32. A limiting plate 511 protrudes from the periphery of the limiting rod 51. The first elastic element 52 is a spring, with one end fixedly connected to the mounting base 1 and the other end fixedly connected to the limiting plate 511, thus driving the limiting rod 51 away from the other rotating arm 32.

[0052] Reference Figure 5 and Figure 6 Meanwhile, a limiting hole 341 is provided at the position of the buckle 34 corresponding to the limiting rod 51. The pressing component 6 is provided on the cover plate 2 and is used to press the end of the limiting rod 51 away from the buckle 34, so that the limiting rod 51 is inserted into the limiting hole 341, further limiting the buckle 34 and the two rotating arms 32 to improve the stability of the buckle 34.

[0053] It should be noted that when the torsion spring 33 is in its natural state, the two rollers 36 are precisely abutting against the buckle 34. At this time, the buckle 34 can accurately engage in the slot 35, making the cover plate 2 flush with the mounting base 1. However, the torsion spring 33 is prone to aging after a certain period of use, affecting its elasticity and thus the position of the buckle 34 in the slot 35, causing the cover plate 2 to be uneven with the mounting base 1. When the limiting rod 51 is inserted into the limiting hole 341, it ensures that the buckle 34 can accurately engage in the slot 35, guaranteeing that the cover plate 2 remains flush with the mounting base 1 even if the torsion spring 33 ages. Simultaneously, it keeps the torsion spring 33 stable in its natural state, slowing down its aging process and thus extending its service life.

[0054] Reference Figure 6 and Figure 7 In some embodiments, the clamping assembly 6 includes a mounting cylinder 61, a clamping rod 62, and a second elastic element 63. The mounting cylinder 61 is fixedly connected to the cover plate 2 on one side of the buckle 34. The mounting cylinder 61 is hollow and has through holes at both ends. The inner wall of the mounting cylinder 61 has a sliding groove 611 along its length and a rotating groove 612 along its circumference. The rotating groove 612 is connected to the end of the sliding groove 611 away from the cover plate 2. At the same time, the cover plate 2 has a connecting hole 22 at the position corresponding to the mounting cylinder 61, and the connecting hole 22 is connected to the interior of the mounting cylinder 61.

[0055] The clamping rod 62 is disposed in the mounting cylinder 61. Specifically, the clamping rod 62 includes a clamping part 621, a limiting part 622, and a rotating part 623. The end of the clamping part 621 away from the cover plate 2 is movably inserted into the mounting cylinder 61 and abuts against the end of the limiting rod 51 away from the buckle 34. The limiting part 622 is fixedly connected to the periphery of the clamping part 621, and a protrusion 624 is formed on the periphery of the limiting part 622. The protrusion 624 is confined in the rotating groove 612. The rotating part 623 is fixedly connected to the end of the clamping part 621 near the cover plate 2 and is located in the connecting hole 22. The second elastic element 63 is also a spring. One end of the second elastic element 63 is fixedly connected to the side of the limiting part 622 away from the cover plate 2, and the other end is fixedly connected to the mounting cylinder 61 to drive the clamping part 621 away from the limiting rod 51.

[0056] In its natural state, the second elastic element 63 drives the pressing part 621 away from the limiting rod 51, causing the rotating part 623 to protrude from the connecting hole 22, and the protrusion 624 to be confined in the sliding groove 611. By pressing the rotating part 623, the protrusion 624 slides along the sliding groove 611 to the end of the sliding groove 611 away from the cover plate 2, causing the pressing part 621 to approach the limiting rod 51, so that the end of the pressing part 621 abuts against the end of the limiting rod 51 away from the buckle 34, thereby pressing the limiting rod 51. Then, the rotating part 623 is rotated again, so that the protrusion 624 is confined in the rotating groove 612, and under the action of the second elastic element 63, the pressing part 621 is stably kept in the pressing state of the limiting rod 51. At this time, the rotating part 623 is located in the connecting hole 22 and is flush with the cover plate 2. The operator can understand the installation status of the pressing assembly 6 by observing the position of the rotating part 623. It should be noted that the rotating part 623 has an internal hexagonal groove 625, so that the rotating part 623 can be pressed and rotated using a common internal hexagonal wrench.

[0057] In some embodiments, a guide groove 512 is provided at one end of the limiting rod 51 near the pressing part 621. As the pressing part 621 approaches the limiting rod 51, the pressing part 621 abuts against the groove wall of the guide groove 512 to guide the movement of the limiting rod 51, thereby driving the limiting rod 51 to move toward the end near the buckle 34, so that the limiting rod 51 can be automatically inserted into the limiting hole 341. At the same time, a chamfer 513 is provided at the end of the limiting rod away from the pressing part 621 to facilitate its insertion into the limiting hole 341.

[0058] Reference Figure 7In some embodiments, a limiting groove 613 is formed at the end of the rotating groove 612 away from the sliding groove 611. The limiting groove 613 is positioned towards the end of the rotating groove 612 near the cover plate 2. When the rotating part 623 is rotated, causing the protrusion 624 to rotate to the end of the rotating groove 612 away from the sliding groove 611, the second elastic member 63 drives the protrusion 624 to engage and limit its position in the limiting groove 613. This effectively restricts the rotation of the clamping rod 62 and minimizes the possibility of the limiting part 622 disengaging from the rotating groove 612, thereby improving the stability of the clamping part 621 clamping the limiting rod 51. It should be noted that in this embodiment, when the protrusion 624 is limited to the limiting groove 613, the rotating part 623 is flush with the cover plate 2.

[0059] In some embodiments, the clamping assembly 6 further includes an elastic pad 64, which is fixedly connected to one end of the mounting cylinder 61 near the cover plate 2 and located in the connecting hole 22. The elastic pad 64 has a certain elasticity. During the pressing of the rotating part 623, when the protrusion 624 is about to enter the rotating groove 612, the rotating part 623 abuts against the elastic pad 64 to provide feedback to the operator that it is necessary to press and rotate the rotating part 623 to facilitate the operation of the clamping assembly 6. Furthermore, when the rotating part 623 rotates, the surface of the rotating part 623 rubs against the elastic pad 64, allowing the operator to rotate the rotating part 623 slowly and steadily so that the protrusion 624 rotates steadily to the end of the rotating groove 612 away from the limiting groove 613, thus avoiding rapid rotation that could cause the rotating part 623 to pop out of the connecting hole 22 and cause wear on the clamping assembly 6, thereby reducing the risk of bumps to the operator. At the same time, the protrusion 624 is confined within the limiting groove 613 and the elastic member, further restricting the movement of the rotating part 623, thereby minimizing the possibility of the limiting part 622 disengaging from the limiting groove 613.

[0060] The implementation principle of this embodiment is as follows: by pressing the rotating part 623, the protrusion 624 slides from one end of the sliding groove 611 to one end of the rotating groove 612. Then, by rotating the rotating part 623, the protrusion 624 rotates to the other end of the rotating groove 612. Under the drive of the second elastic member 63, the protrusion 624 is locked in the limiting groove 613. During this process, the pressing part 621 abuts against the groove wall of the guide groove 512 of the limiting rod 51, so that the limiting rod 51 moves toward the end close to the buckle 34. Finally, the pressing part 621 abuts against one end of the limiting rod 51, so that the other end of the limiting rod 51 is inserted into the limiting hole 341, further limiting the buckle 34 and the two rotating arms 32 to improve the stability of the buckle 34.
