[0002] Unmanned aircraft, also known as "drones", are unmanned aircraft that are controlled by radio remote control equipment and self-contained program control devices, or are operated completely or intermittently autonomously by onboard computers. With the development of drone technology, in the field of drone technology, the use of drone-mounted shouting devices can achieve directional approach to the shouting location and can transmit the shouting content more clearly.

[0003] However, when encountering traffic control, rescue sites and other situations at night, the staff cannot make corresponding shouting instructions based on the specific conditions on the scene. Therefore, a lighting lamp is usually installed on the shouting device to observe the specific conditions on the scene and indicate the direction of the road for the person being shouted at. Since most of the lighting lamps installed on some shouting devices on the market are fixed by knobs, due to the small size of the knobs, users need to rotate the knobs several times to complete the installation and removal. At the same time, due to the small space of the installation location, users are easily limited by space when rotating the knobs by hand, which is inconvenient to use and even has the risk of over-rotation and disengagement.

[0030] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0031] The embodiment of the present application provides a loudspeaker with a detachable lighting mechanism, which can solve the problem of inconvenient installation and removal of lighting lamps carried by some loudspeakers on the market.

[0032] Figure 1 is a schematic diagram of a shouting device with a detachable lighting mechanism in this application, referring to Figure 1 As shown, the loudspeaker device with a detachable lighting mechanism comprises: a loudspeaker 3, a lighting mechanism 4 and a mounting plate 5, wherein the mounting plate 5 is fixedly mounted on the loudspeaker 3, and the lighting mechanism 4 is detachably mounted on the mounting plate 5. In this embodiment, the mounting plate 5 is fixed to the bottom of the loudspeaker 3, and the lighting mechanism 4 is detachably plugged in front of the mounting plate 5.

[0033] like Figure 2 As shown, a first embodiment of a detachable lighting mechanism mounted on a mounting plate is provided. In this embodiment, the lighting mechanism 4 also includes a lighting lamp 41, and the lighting lamp 41 is also fixedly connected to an insertion block 42, and a card slot 43 is also provided on the side wall of the insertion block 42. The mounting plate 5 is provided with a slot 51 that can accommodate the insertion block 42, and the slot 51 and the insertion block 42 can cooperate with each other, for example: if the internal space of the slot 51 is a cube, then the insertion block 42 is a cube; if the internal space of the slot 51 is a cylinder, then the insertion block 42 is a cylinder.

[0034] The mounting plate 5 also includes a groove 52 and an embedded air pressure chamber 53, one end of the air pressure chamber 53 extends to the edge of the mounting plate 5, and the other end extends to the groove 52. A retractable pull rod 54 and a piston rod 55 are connected to the two ends of the air pressure chamber 53, respectively. Since the air pressure in the air pressure chamber 53 needs to be kept constant, no matter the pull rod 54 at one end of the air pressure chamber 53 is pulled or pushed, the piston rod 55 at the other end of the air pressure chamber 53 will also move accordingly. The end of the pull rod 54 is located outside the mounting plate 5, which is convenient for users to pull or push.

[0035] A stopper 56 is also connected to the piston rod 55, which is mainly used to cooperate with the slot 43 on the insertion block 42, and can fasten the insertion block 42 in the slot 51 to prevent the insertion block 42 from falling out. A guide surface is also provided on the stopper 56 in the direction of the slot 51 notch, wherein the guide surface can be an inclined surface or an arc surface. During the installation of the lighting mechanism 4, when the insertion block 42 hits the guide surface of the stopper 56, under the push of external force, the piston rod 55 will be driven to move by squeezing the stopper 56, and then the pull rod 54 at the other end of the air pressure chamber 53 will move outward, so that the stopper 56 is completely moved into the groove 52, and the insertion block 42 is completely inserted into the slot 51. In addition, for more convenient insertion, the user can also manually pull out the pull rod 54 during the movement of the insertion block 42, and the stopper 56 will move into the groove 52 with the piston rod 55. The two move in coordination, which is more convenient and labor-saving, and relatively reduces the wear of the insertion block 42 and the stopper 56.

[0036] When the insertion block 42 is fully inserted into the slot 51, and a receiving space is formed between the card slot 43 on the insertion block 42 and the groove 52 on the mounting plate 5, the user pushes the pull rod 54, and the air pressure in the air pressure chamber 53 pushes the piston rod 55, thereby pushing the stopper 56 into the receiving space, for example, at least two-thirds of the volume of the stopper 56 is located in the card slot 43. This helps prevent the insertion block 42 from falling out of the slot 51, and the insertion block 42 is fixed on the illuminating lamp 41, so that the installation of the illuminating mechanism 4 can be easily completed.

[0037] like Figure 2 As shown, during the disassembly of the lighting mechanism 4, the pull rod 54 needs to be manually pulled out, and the piston rod 55 at the other end of the air pressure chamber 53 will also move accordingly, and the piston rod 55 will also move into the groove 52 with the stopper 56. At this time, it is only necessary to manually pull the lighting lamp out of the slot 51 along with the insertion block 42 to complete the disassembly of the lighting mechanism 4. This disassembly method only requires a simple pull of the pull rod 54 to complete the disassembly process of the lighting mechanism 4, which is simple and convenient for daily use.

[0038] like Figure 2 As shown, in this embodiment, a distance is left between the end of the insertion block 42 and the bottom of the slot 51, as shown in FIG. Figure 2As shown, in some embodiments, the mounting plate 5 may further include a second spring 58 fixedly arranged at the bottom of the slot 51. When the insertion block 42 is not inserted into the slot 51, the second spring 58 is in a free state; when the insertion block 42 is fully inserted into the slot 51, the second spring 58 is in a compressed state. By arranging the second spring 58 at the bottom of the slot 51, when the lighting mechanism 4 is installed, the second spring 58 will be gradually compressed, which can play a certain buffering role in the insertion of the insertion block 42; when the lighting mechanism 4 is disassembled, the compressed second spring 58 can provide elastic force to facilitate the insertion of the insertion block 42, which is conducive to the disassembly of the lighting mechanism 4.

[0039] In one embodiment, the insertion block 42 can also match the slot 51. When the insertion block 42 is fully inserted into the slot 51, the end of the insertion block 42 contacts the bottom of the slot 51 (not shown), and the stopper 56 partially falls into the accommodating space.

[0040] In addition, in one embodiment, the air pressure chamber 53 may be an "L" shaped structure, one end of which is connected to the groove 52, the piston rod 55 is telescopically arranged at the end, and the other end of the air pressure chamber 53 extends to the edge of the mounting plate 5. The advantage of the "L" shaped structure is that it can be turned and arranged, and the lighting mechanism 4 can be better fixed without increasing the structural complexity of the lighting mechanism 4.

[0041] like Figure 3 As shown, a second embodiment of a detachable lighting mechanism installed on a mounting plate is provided. In this embodiment, a first spring 57 is also sleeved on the piston rod 55, and the two ends of the first spring 57 abut against the stopper 56 and the inner wall of the groove 52 respectively. When the lighting mechanism 4 is not installed, the first spring 57 is in a free state, and a part of the stopper 56 extends out of the groove 52 and is located in the slot 51. When installing the lighting mechanism 4, the insertion block 42 can be directly inserted into the slot 51, and under the action of external force, the insertion block 42 squeezes and moves the stopper 56 along the guide surface of the stopper 56 into the groove 52, at which time the first spring 57 between the stopper 56 and the groove 52 is in a compressed state; until the accommodation space formed by the groove 52 and the card slot 43 on the insertion block 42 can completely accommodate the stopper 56, the first spring 57 will release the elastic force and return to the free state, pushing the stopper 56 into the accommodation space. In this way, it can be ensured that when installing the lighting mechanism 4, there is no need to use the pull rod 54, and the installation can be completed by pushing the insertion block 42 into the slot 51, which is simple and convenient to operate and saves time. The other structures of this embodiment are the same as those of the first embodiment and will not be described again here.

[0042] like Figure 2 and Figure 3As shown, in some embodiments, a deceleration mechanism 6 is provided at the end of the insertion direction of the insertion block 42, so that when the insertion block 42 is inserted into the slot 51, the deceleration mechanism 6 contacts the side wall of the slot 51, thereby playing a certain deceleration role, wherein the deceleration mechanism 6 needs to be located outside the second spring 58, and the two cannot intersect, otherwise it will cause the second spring 58 and the deceleration mechanism 6 to collide, thereby affecting the insertion block 42 from entering the slot 51.

[0043] Reference Figure 4 As shown in FIG. 1 , it is a cross-sectional schematic diagram of the deceleration mechanism in this application. Figure 4 As shown, in some embodiments, the deceleration mechanism 6 may further include a bracket 61, which is fixedly disposed on the insertion block 42, and a roller 62 is hinged on the bracket 61. A square groove 63 is radially provided on the surface of the roller 62, and a third spring 64 is fixedly disposed at the bottom of the square groove 63, and a resistance block 65 is also connected to the other end of the third spring 64. During the insertion of the insertion block 42 into the slot 51, the roller 62 on the bracket 61 contacts the side wall of the slot 51, and as the insertion block 42 moves, the roller 62 rotates by friction with the side wall of the slot 51, and the resistance block 65 does not affect the movement of the insertion block 42 when it is completely in the square groove 63. In this embodiment, the bracket 61 includes two arms, and the roller 62 is hinged between the two arms; a square groove 63 is provided on the surface of the roller 62 at both ends along the diameter, and the bottom of each square groove 63 is connected to a resistance block 65 through the third spring 64.

[0044] like Figure 4 As shown, in some embodiments, the resistance block 65 has a sawtooth surface with concave and convex portions, and the resistance block 65 is made of rubber. By setting the surface of the resistance block 65 to be a sawtooth surface with concave and convex portions, and the material of the resistance block 65 is a rubber material, the friction between the resistance block 65 and the side wall of the slot 51 can be increased, thereby achieving a better buffering effect.

[0045] The friction between the resistance block 65 and the square slot 63 is greater than the gravity of the resistance block 65. Only when the friction is greater than the gravity, the roller 62 will roll along the side wall of the slot 51 to press the resistance block 65 back into the square slot 63, thereby preventing the resistance block 65 from obstructing the insertion block 42 from being inserted into the slot 51.

[0046] In a second aspect, the present application also provides a drone. Figure 5 As shown, the UAV includes a UAV body 1, which also includes a three-axis gimbal 2, and a loudspeaker device of any of the above-mentioned embodiments is installed on the three-axis gimbal 2. In this way, the UAV can provide lighting and loudspeaker functions during flight, and can also freely adjust the direction and angle of the loudspeaker 3 to a suitable degree.
