Description

Technical Field

[0001] The utility model relates to the technical field of lighting equipment, in particular to a remote-controlled searchlight. Background Art

[0002] A searchlight is a lamp used for long-distance lighting, searching and rescue. Its principle is to gather the light emitted by the light source into a certain range to achieve the effect of focusing, thereby obtaining a greater light intensity within a certain range to realize the function of searchlighting. It has the advantages of being sturdy, durable, moisture-proof and rain-proof.

[0003] For example, a Chinese patent document with the authorization number CN215112493U discloses a small-sized long-distance searchlight device, including a lamp body and a pan-tilt supporting the lamp body, the lamp body including an outer shell surrounded by an upper cover of the lamp body, a front cover of the lamp body and a lower cover of the lamp body, a lamp tube, a vertical rotation mechanism and a first control panel are arranged in the shell cavity of the outer shell, the vertical rotation mechanism is fixed on the lower cover of the lamp body and is transmission-connected to the lamp tube, and is used to control the turning of the lamp tube in the vertical direction, the first control panel is fixed on the rear side wall of the lower cover of the lamp body and is electrically connected to the vertical rotation mechanism, the pan-tilt includes a horizontal rotation mechanism, a second control panel and a pan-tilt bottom cover, and the lamp body also includes a vertical limiter The vertical limit mechanism includes a limit fixing plate, an upper limit sensor and a lower limit sensor. The lamp tube is provided with a sensing piece for contacting and cooperating with the upper limit sensor and the lower limit sensor at the position corresponding to the vertical limit mechanism. Although the above-mentioned searchlight device can limit the up and down rotation angles in the vertical direction through the vertical limit mechanism, the horizontal rotation mechanism cannot detect the maximum horizontal rotation angle when driving the lamp body to rotate horizontally. When it rotates to the maximum angle and the remote control is not released, the horizontal drive motor will still rotate, which may easily cause slippage and wear between the gears. In addition, the motor may also burn out due to the increase of current caused by stalling, thereby affecting the service life.

[0004] Therefore, it is necessary to improve the deficiencies in the above prior art. Summary of the invention

[0005] The technical problem to be solved by the utility model is to provide a remote control searchlight in view of the deficiencies of the above-mentioned prior art, so as to solve the problem that the prior art cannot detect the maximum horizontal rotation angle, resulting in the motor not being able to stop automatically after turning to the maximum angle, causing slippage and wear between gears or burning due to blocking.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a remote-controlled searchlight, comprising a lamp body and a pan-tilt supporting the lamp body, the lamp body comprising an outer shell and a lamp tube vertically rotatably connected to the outer shell, a control panel being installed in the outer shell, a vertical rotation mechanism being also provided in the outer shell capable of driving the lamp tube to vertically rotate relative to the outer shell, a horizontal rotation mechanism being provided between the outer shell and the pan-tilt capable of driving the lamp body to horizontally rotate relative to the pan-tilt, the horizontal rotation mechanism comprising a horizontal mounting plate fixedly installed in the outer shell, a driving mechanism fixedly installed on the horizontal mounting plate, and a driving connecting member fixedly installed on the upper end of the pan-tilt and cooperating with the driving mechanism, the lower end of the outer shell is rotatably connected to the upper end of the pan-tilt, and a horizontal detection mechanism being provided between the horizontal mounting plate and the driving connecting member capable of detecting the horizontal rotation of the lamp body relative to the pan-tilt to the maximum rotation angle boundary.

[0007] By adopting the above technical solution, when the remote control is used to remotely start the driving mechanism and cooperate with the driving connector on the gimbal, the lamp body is driven to rotate horizontally relative to the gimbal under the reaction force, the horizontal detection mechanism detects that the lamp body has turned to the maximum rotation angle boundary and triggers a signal to the control board. After receiving the signal, the control board controls the driving mechanism to automatically stop running, avoiding damage to related components of the horizontal detection mechanism due to failure to release in time, thereby extending the service life.
