The term "and / or" as used in the present specification includes any and all combinations of one or more of the associated listed items.

[0026] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as there is no conflict.

[0027] Please refer to Figure 1 and Figure 2 , the indicator lamp comprises a lampshade 10, a circuit board 20, a cover 30, a sealing assembly 40, a damping assembly 50 and a mounting plate 60.

[0028] The circuit board 20 is arranged in the inner space of the lampshade 10, and specifically, the circuit board 20 is provided with LED light emitting elements for emitting indicating light. The circuit board 20 is connected with an external power supply through wires for supplying power to the LED light emitting elements. The cover 30 is used to cover the lampshade 10 to form a sealed cavity. The cavity is used to accommodate and protect the circuit board 20 and other electronic components. The cover 30 and the lampshade 10 are connected in a buckling manner, which has good assembly convenience. The sealing assembly 40 is arranged at the connection between the cover 303 and the lampshade 10. The sealing assembly 40 is made of elastic material and deforms when the cover 30 and the lampshade 10 are buckled, thereby forming a reliable sealing effect. Through the arrangement of the sealing assembly 40, it can effectively prevent rainwater, dust and other external substances from entering the cavity. The damping assembly 50 is arranged at the outer periphery of the lampshade 10 and is used to connect with the mounting plate 60. The damping assembly 50 is made of elastic material and can absorb and buffer external vibration to avoid direct transmission of vibration to the internal components such as the circuit board 20. The mounting plate 60 is used to mount the entire indicating lamp on a use device such as a drone.

[0029] The indicating lamp of the embodiment forms a sealed cavity through the lampshade 10 and the cover 30, and the sealing assembly 40 is arranged therebetween to achieve IP67 level waterproof effect. At the same time, by arranging the damping assembly 50 at the outer periphery of the lampshade 10 and connecting with the mounting plate 60, the influence of external vibration on the internal components of the indicating lamp is effectively reduced. This structure design is simple, convenient to assemble, and has good waterproofness and anti-vibration performance, and is especially suitable for devices such as drones used in harsh environments.

[0030] Please continue to refer to Figure 2 , the cover 30 is provided with an annular groove 31 extending along the circumference of the cover 30 to form a closed ring. The depth and width of the annular groove 31 are optimized to match the size of the sealing member. The sealing assembly 40 includes an annular sealing member 41 and a fixing assembly 42, wherein the annular sealing member 41 is made of elastic material such as rubber and is arranged in the annular groove 31 on the cover 30. When the cover 30 is buckled with the lampshade 10, the annular sealing member 41 will be moderately deformed, thereby forming a reliable sealing effect between the cover 30 and the lampshade 10.

[0031] Please refer to Figure 3In order to further improve the stability of the overall structure, the embodiment also designs a fixing assembly 42. The fixing assembly 42 includes a first limiting part 401 and a second limiting part 402 that cooperate with each other. The first limiting part 401 is arranged on the cover body 30 and can be a protrusion or a groove structure; the second limiting part 402 is arranged on the lampshade 10 and is matched in shape with the first limiting part 401. When the cover body 30 is assembled with the lampshade 10, the first limiting part 401 and the second limiting part 402 are engaged with each other to form a fixing structure 42 for limiting the rotation of the cover body 30 relative to the lampshade 10. This design not only enhances the stability of the overall structure, but also avoids the sealing failure caused by rotation.

[0032] In the embodiment of the present application, through the cooperative design of the annular groove 31, the annular sealing element 41 and the fixing assembly 42, the embodiment not only guarantees the waterproof performance, but also improves the assembly precision and use reliability of the product. The design of the fixing assembly 42 solves the rotation problem that may occur in the traditional structure, so that the product maintains stable sealing effect during use.

[0033] Please refer to Figure 4 The lampshade 10 is provided with a through hole 11 for mounting and fixing. Correspondingly, the mounting plate 60 is provided with a threaded part 61 for forming a threaded connection with the fastener 52. The damping assembly 50 includes a buffer ring 51 and a fastener 52, wherein the buffer ring 51 is made of a material such as rubber that has good damping performance. The fastener 52 passes through the through hole 11 of the lampshade 10 and the buffer ring 51 in sequence, and finally forms a threaded connection with the threaded part 61 of the mounting plate 60. During installation, the abutting surface of the fastener 52 is in compression fit with the surface of the buffer ring 51, which ensures the stability of the damping structure.

[0034] In order to further optimize the damping effect, the damping assembly 50 also includes a limiting ring 53. The limiting ring 53 is sleeved on the fastener 52, and the two ends thereof are in abutment with the buffer ring 51 and the fastener 52, respectively. This design not only enhances the stability of the overall structure, but also provides better damping effect. The arrangement of the limiting ring 53 effectively prevents the deformation or displacement of the buffer ring 51 during use, ensuring the persistent stability of the damping performance.

[0035] In the embodiment of the present application, considering the uniformity of the damping effect, the embodiment adopts a multi-point damping design. Specifically, a plurality of damping assemblies 50 are arranged on the outer periphery of the lampshade 10, and these damping assemblies 50 are uniformly distributed along the outer periphery of the lampshade 10. This uniform distribution design ensures that the indicator lamp can be effectively buffered and protected when subjected to vibration in various directions.

[0036] In the embodiment of the present application, through the combined design of the buffer ring 51, the fastener 52 and the limiting ring 53, a complete damping system is formed, which can effectively absorb and buffer various vibrations, and the evenly arranged multiple points ensure the all-round damping effect. The design of the whole damping structure is convenient for installation and maintenance, and has a good service life.

[0037] Referring to Figure 5 The cover 30 is provided with a wire outlet hole 32 for the wires of the circuit board 20 to pass out. In order to ensure the waterproof performance of the wire outlet, the indicator lamp of the embodiment further comprises a waterproof assembly 70 arranged at the wire outlet hole 32. The waterproof assembly 70 is connected with the wire outlet hole 32 in a sealing fit manner to form a reliable waterproof structure.

[0038] The waterproof assembly 70 comprises two parts of an elastic sealing sleeve 71 and a compression nut 72. The elastic sealing sleeve 71 is made of a material such as silica gel which has good elasticity and sealing performance, and is arranged in the wire outlet hole 32 of the cover 30. The center of the elastic sealing sleeve 71 is provided with a center hole (not shown in the figure), and the diameter of the center hole (not shown in the figure) is slightly smaller than the outer diameter of the wire, so that a moderate deformation is generated when the wire passes through, thereby forming a preliminary sealing effect. The compression nut 72 is connected with the cover 30 in a threaded connection manner. When the compression nut 72 is tightened, an axial pressure is generated on the elastic sealing sleeve 71. Under the action of the pressure, the elastic sealing sleeve 71 is deformed in the radial direction, so that the contact between the elastic sealing sleeve 71 and the wire is more closely, thereby forming a more reliable sealing effect. This design utilizes the characteristics of the silica gel material, and realizes the all-round sealing of the wire by converting the axial pressure into the radial pressure.

[0039] In the embodiment of the present application, the sealing sleeve made of flexible material of the waterproof assembly 70 can adapt to different specifications of wires, and the sealing pressure can be adjusted through the threaded fastening manner to ensure the best sealing effect. The whole structure is convenient for installation and maintenance, and can be easily operated when the wire needs to be replaced. Through the design of the waterproof assembly 70, the problem of water seepage at the wire outlet is effectively solved, and the waterproof performance of the whole indicator lamp is improved. The structure is suitable for the unmanned aerial vehicle indicator lamp which needs to be used in bad environments such as rainy days, and can ensure the reliable operation of the internal electronic elements.

[0040] Referring to Figure 6 A positioning structure for fixing the circuit board 20 is arranged in the lampshade 10, and the positioning structure comprises a first support part 81 and a second support part (not shown in the figure). The double support design ensures that the circuit board 20 can be stably maintained at the preset position after installation, and avoids the position deviation caused by vibration or collision.

[0041] Specifically, the first support part 81 extends from the inner wall of the lampshade 10 to form a stable support platform. The first support part 81 abuts against one side of the circuit board 20 to provide preliminary positioning and support for the circuit board 20. By precisely controlling the extension length and angle of the first support part 81, it is ensured that the circuit board 20 can be kept in the optimal working position after installation, so that the light of the LED light-emitting element can achieve the best projection effect. The second support part (not shown in the figure) is arranged on the inner wall of the lampshade 10. When the cover 30 is assembled with the lampshade 10, the second support part (not shown in the figure) cooperates with the cover 30 to apply appropriate pressure to the circuit board 20, thereby firmly fixing the circuit board 20 in the preset position. This compression and fixing method not only ensures the stability of the installation of the circuit board 20, but also facilitates the later maintenance and replacement.

[0042] In the embodiment, the positioning structure provides more reliable fixing effect, and the cover 30 itself is used as part of the fixing structure 42, so that the overall structure is simplified. This design facilitates the installation and disassembly of the circuit board 20, and improves the maintainability of the product. Through the above design, the embodiment not only solves the technical problem of fixing the circuit board 20, but also improves the overall assembly efficiency and use reliability of the product. The fixing structure 42 is suitable for unmanned aerial vehicle indicator lights that need to be used in a high-vibration environment, and can ensure that the circuit board 20 maintains a stable and reliable working state under various working conditions.

[0043] The embodiment of the application provides an indicator light, which comprises a lampshade 10, a circuit board 20, a cover 30, a sealing assembly 40, a mounting plate 60 and a damping assembly 50. The circuit board 20 is arranged in the lampshade 10. The cover 30 is used for covering the lampshade 10. The sealing assembly 40 is arranged between the cover 30 and the lampshade 10. The damping assembly 50 is arranged on the outer periphery of the lampshade 10. The damping assembly 50 is used for being connected with the mounting plate 60. Through the cooperation of the lampshade 10, the cover 30 and the sealing assembly 40, a sealing structure is formed, which can achieve an IP67 waterproof level. The problem of short circuit failure of internal components caused by rainwater penetration in the prior art is effectively solved. By arranging the damping assembly 50 on the outer periphery of the lampshade 10 and connecting the damping assembly 50 with the mounting plate 60, the adverse effects of high-frequency vibration of the unmanned aerial vehicle on the indicator light are reduced, and the fault of broken mounting ears is avoided. Through the double protection scheme of waterproofing and damping, the reliable operation of the indicator light in severe weather and severe flight conditions is ensured, and the stability and safety of the entire unmanned aerial vehicle system are improved.

[0044] The application further provides a specific application example of applying the indicator lamp described in the foregoing embodiments to a UAV system. In the UAV application scenario, the installation position of the indicator lamp is usually set at the center position of the fuselage, for indicating the working state of the UAV. The indicator lamp is firmly fixed on the UAV fuselage through the mounting plate 60, and the damping assembly 50 can effectively absorb the vibration generated in the flight process, preventing the vibration from causing damage to the internal elements of the indicator lamp. In actual application, the waterproof design of the indicator lamp is particularly important. When the UAV performs a task in rainy days or a high-humidity environment, the dual protection of the sealing assembly and the waterproof assembly effectively prevents water from penetrating into the lamp interior, ensuring the normal work of electronic elements such as the circuit board. The IP67-level waterproof performance enables the UAV to continuously and reliably operate under various adverse weather conditions.

[0045] The above description is merely an example of the application, and does not limit the patent scope of the application.
