[0002] Unmanned aerial vehicles (UAVs) are widely used in industrial applications, such as night patrols. However, when using UAVs for night patrols, they need to be equipped with searchlights. To increase the lighting intensity, some searchlights use dual-lamp mode. Figure 1 It is a common double-tube searchlight. The rotating shaft 1 of the searchlight 3 is set on the outside. The rotation angle of the rotating shaft 1 is limited by the housing 2 of the searchlight and the housing of the unmanned aerial vehicle, resulting in a limited rotation angle of the searchlight 3, thereby affecting the lighting range of the searchlight 3. In addition, some searchlights are also equipped with a loudspeaker 4, which further affects the rotation angle of the rotating shaft. Utility Model Content
[0003] In order to improve the lighting range of the searchlight, the utility model provides a double-lamp tube searchlight.
[0004] The utility model proposes a double-lamp searchlight, which adopts the following technical solutions:
[0005] A dual-lamp tube searchlight for use with an unmanned aerial vehicle comprises a housing, a searchlight assembly, and a drive unit.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Those skilled in the art should know that the embodiments described below are part of the embodiments disclosed in the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.
[0020] The present application embodiment discloses a double-lamp searchlight, referring to Figures 2 to 4 The searchlight is used for an unmanned aerial vehicle and includes a housing 10 , a searchlight assembly, and a driving unit 30 .
[0021] The housing 10 has a receiving cavity, a first opening, and a second opening. The first opening and the second opening are respectively located on both sides of the housing 10, and the first opening and the second opening are both connected to the receiving cavity. The housing 10 can be made of a material with a certain hardness and strength (such as hard plastic) to protect its internal structure. In addition, the housing 10 includes an upper shell 11 and a lower shell 12, and the upper shell 11 and the lower shell 12 are connected by screws to facilitate installation and disassembly. Specifically, the screws between the upper and lower shells 12 can be captive thumb screws, which are easy to install and will not fall off easily.
[0022] The searchlight assembly is connected to the housing 10 and includes a first lamp body 20, a second lamp body 40, and a rotating shaft 50. The rotating shaft 50 is disposed within the accommodating cavity and can be made of a material having a certain hardness and strength (such as an aluminum alloy) to provide the rotating shaft 50 with a higher structural strength. The rotating shaft 50 includes a shaft body 51 and connecting portions 52 disposed at both ends of the shaft body 51. The middle section of the shaft body 51 is bent outward to form a curved portion. The first lamp body 20 and the second lamp body 40 are respectively connected to the shaft body 51 via the connecting portions 52. The internalization of the rotating shaft 50 within the housing 10 resolves the limitation of the searchlight's external structure on the travel of the rotating shaft 50, thereby greatly increasing the searchlight's rotational travel. It also resolves the impact of the protruding rotating shaft 50 on the visual appearance.
[0023] The drive unit 30 is disposed within the accommodating cavity and is arranged transversely. Specifically, the drive unit 30 includes a servo. The drive unit 30 is partially located within the curved portion of the shaft body 51, enabling the shaft body 51 to rotate about the drive unit 30 by a predetermined angle. The output shaft of the drive unit 30 is connected to the end of the connecting portion 52 that is distal from the first lamp body 20. The drive unit 30 is used to drive the rotating shaft 50 to rotate. The direct connection between the drive unit 30 and the rotating shaft 50, without an intermediate transmission link, eliminates energy loss due to mechanical friction and eliminates motion hysteresis.
[0024] Optionally, the output shaft of the driving unit 30 is connected to the connecting portion 52 via a connecting member 31 to improve the connection strength between the driving unit 30 and the rotating shaft 50. Specifically, the connecting member 31 includes a connecting sleeve and a connecting block connected to the outside of the connecting sleeve. The connecting sleeve is embedded in the connecting portion 52, and the output shaft of the driving unit 30 is embedded in the connecting sleeve. The connecting block is fixed to the driving unit 30 by screws.
[0025] Optionally, the shaft body 51 includes a main shaft and side shafts connected to both ends of the main shaft, and the angle between the main shaft and the side shaft is set between 100-130°. For example, the angle between the main shaft and the side shaft can be 120°, so that the bending part can match the driving part 30 to avoid affecting the rotation stroke of the rotating shaft 50.
[0026] In some embodiments, the connecting portion 52 is a cylindrical structure with openings at both ends. Both the first lamp body 20 and the second lamp body 40 include a lamp body 21 and a connecting arm connected to the lamp body 21. The connecting arm is inserted into the connecting portion 52 through the opening, and the connecting portion 52 and the connecting arm are fixed to each other by screws. This arrangement facilitates the connection of the connecting arm to the rotating shaft 50 and also helps improve the connection strength between the connecting arm and the rotating shaft 50.
[0027] In some embodiments, the connecting arm includes an extension portion 22 connected to the connecting portion 52 and a main arm 23 connected to the extension portion 22, and the angle between the extension portion 22 and the main arm 23 is set between 100-120°, for example, the angle between the extension portion 22 and the main arm 23 is 120° to improve visual aesthetics.
[0028] It should be noted that, in addition to the searchlight, the lamp body 21 may also include a warning light, a neon light or a laser light. The searchlight light, the warning light, the neon light or the laser light may be emitted from the same lens.
[0029] Optionally, in order to further improve the stability of the driving part 30, the driving part 30 is connected to the inner wall of the lower shell 12 through a clamp 13, and the clamp 13 and the lower shell 12 are fastened by screws.

They are only for the purpose of facilitating the explanation of the scheme of the present invention and simplifying the description, rather than explicitly or implicitly indicating that the devices or elements involved must have the specific orientation, be constructed and operated in a specific orientation. Therefore, the above-mentioned orientation or positional relationship terms cannot be understood or interpreted as limitations on the scheme of the present invention.
