Description

Technical Field

[0001] This application relates to the field of lighting equipment technology, and in particular to an automated searchlight. Background Technology

[0002] Searchlights, as an important lighting device, are widely used in various scenarios at night or in low-light conditions, such as road monitoring, industrial production, and military reconnaissance. Currently, to meet the needs of different application scenarios, existing searchlights are typically equipped with multiple adjustment mechanisms to change the illumination range and direction.

[0003] The existing searchlights are rotatably connected to the support base, and the direction of the searchlight beam is changed by rotating. However, during the rotation of the searchlight relative to the support base, the connection between the searchlight and the support base is prone to wear, which can cause the searchlight to loosen. When the searchlight is used for outdoor operations, wind and vibration will exacerbate the loosening of the searchlight, causing it to deflect easily under the influence of gravity and unable to maintain a fixed beam angle. Utility Model Content

[0004] The purpose of this application is to overcome the above-mentioned technical problems and provide an automated searchlight.

[0005] An automated searchlight includes:

[0006] The searchlight body includes a housing, an illumination component, and a heat dissipation component. The housing is cylindrical and has a lens at one end. The housing covers the illumination component and the heat dissipation component. The heat dissipation component is located at the rear of the housing, and the illumination component is located on the side of the heat dissipation component facing the lens.

[0007] The control device includes an elevation adjustment box and a focus adjustment box located on both sides of the housing. The focus adjustment box controls the focus of the searchlight body. The elevation adjustment box includes a first drive motor, a first transmission worm gear, and a first transmission worm wheel fixed to the searchlight body. The first drive motor drives the first transmission worm gear to rotate, and the first transmission worm gear drives the first transmission worm wheel to rotate.

[0008] The support includes a bracket and a base. The bracket is U-shaped and located at the bottom of the searchlight body. Both ends of the bracket are connected to the focus adjustment box and the elevation adjustment box, respectively. The bottom of the bracket is connected to the base, and the base can control the rotation of the bracket.

[0009] By adopting the above scheme, the elevation adjustment box on the side of the searchlight body can control the elevation angle of the searchlight body, the focal length adjustment box can adjust the focal length of the lens, and the first drive motor inside the elevation adjustment box drives the first transmission worm gear to rotate, which in turn drives the first transmission worm wheel to rotate, thereby realizing the rotation of the searchlight body in the vertical direction, thus realizing the change of the elevation angle of the searchlight body. Since the first transmission worm wheel and the searchlight body are in a fixed state, the rotating parts of the searchlight body will not wear or loosen due to rotation. When the first transmission worm gear is in a fixed state, the first transmission worm wheel is also in a fixed state, so the searchlight body will not rotate arbitrarily, and the elevation angle of the searchlight can be kept in a fixed state, avoiding the unstable illumination direction of the searchlight due to the loosening of the rotating parts of the searchlight.

[0010] In one embodiment, the base includes a second drive motor, a second transmission worm gear, and a second transmission worm wheel. The second drive motor drives the second transmission worm gear through a gear set. The second transmission worm gear cooperates with the second transmission worm wheel, and the second transmission worm wheel is fixed to the bottom of the bracket.

[0011] By adopting the above scheme, the second drive motor drives the second transmission worm to rotate, the second transmission worm drives the second transmission worm wheel to rotate, and the rotating worm wheel drives the bracket to rotate, thereby controlling the illumination direction of the searchlight body.

[0012] In one embodiment, the second drive motor, the second transmission worm, and the second transmission worm wheel are all located on the same plane parallel to the upper and lower surfaces of the base.

[0013] By adopting the above solution, the height of the base can be reduced, thus reducing the space occupied by the base.

[0014] In one embodiment, the heat dissipation assembly includes a cooling fan and heat dissipation fins, the heat dissipation fins extending radially toward the inner wall of the housing.

[0015] By adopting the above solution, the heat dissipation fins can absorb the heat emitted by the searchlight, and the cooling fan can expel the hot air from inside the searchlight.

[0016] In one embodiment, the cooling fan includes an intake fan and an exhaust fan, the intake fan being located on the side of the heat sink fins away from the lens, and the exhaust fan being located on the side of the heat sink fins facing the lens.

[0017] By adopting the above solution, the intake fan can draw in cold air from the outside into the searchlight body to dissipate heat from the searchlight body, and the exhaust fan can expel the hot air inside the searchlight. The cold air drawn in by the intake fan can flow through the heat dissipation fins, enhancing the heat dissipation effect of the heat dissipation fins.

[0018] In one embodiment, the outer shell is double-layered, comprising an inner shell and a buffer shell, the buffer shell covering the inner shell, the lighting assembly and heat dissipation fins being located within the inner shell, and multiple buffer components being fixed between the inner shell and the buffer shell.

[0019] By adopting the above solution, when the searchlight body collides, the inner shell floats inside the outer shell through the buffer component, preventing the parts inside the inner shell from being damaged by strong vibration.

[0020] In one embodiment, the cooling fan is located between the inner housing and the buffer housing, the bottom of the inner housing is provided with a vent hole, and the inner wall of the inner housing abuts against the cooling fins.

[0021] By adopting the above solution, the airflow guided by the cooling fan can continue to circulate through the inner casing, and the inner casing can absorb the heat from the cooling fins, thereby achieving the effect of heat dissipation.

[0022] In one embodiment, the buffer is rib-shaped and extends to both ends of the searchlight body. The buffer is fixed in an array to the outer peripheral surface of the inner housing and the side facing away from the inner housing is fixed to the inner wall of the buffer shell. The cross-section of the buffer is wavy.

[0023] By adopting the above scheme, the cross-section of the buffer is set to be wavy, so that the buffer has good elasticity in the direction of the line connecting with the axis of the inner shell.

[0024] In one embodiment, the top of the buffer housing is provided with a vent hole, and the extended end of the buffer member located above the control device is provided with a drain hole.

[0025] By adopting the above solution, air can be cooled on the top of the searchlight body through the vent on the top of the buffer shell. On rainy days, rainwater seeps into the space between the buffer shell and the inner shell through the vent. Since there is a gap at the connection between the control device and the searchlight body, rainwater can easily seep into the gap and damage the internal electronic components. The buffer component located above the control device can guide the rainwater into the drainage hole to flow out, thus achieving a waterproof effect.

[0026] In one embodiment, the buffer member located above the drain hole is provided with a seepage hole, which is located at the contact surface between the buffer member and the inner shell.

[0027] By adopting the above solution, on rainy days, rainwater slowly seeps downwards along the outer periphery of the inner shell through the seepage holes on the buffer component. During the seepage process, the rainwater can reduce the temperature of the inner shell and achieve the effect of heat dissipation. As the rainwater continues to seep, it can reach the buffer component connected to the drainage hole.

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

[0029] 1. By installing a motor-driven worm gear and a worm wheel fixed to the searchlight body inside the elevation adjustment box and base, the worm drives the worm wheel to rotate, thereby realizing the automatic adjustment of the searchlight direction. Since the worm wheel and the searchlight body are in a fixed state, the searchlight body and the worm wheel will not wear or loosen due to rotation. When the worm is in a fixed state, the worm wheel is also in a fixed state, so the illumination of the searchlight body will not be arbitrarily deflected under the action of gravity.

[0030] 2. By installing an exhaust fan on the side of the heat dissipation fins facing the lens, an intake fan on the side of the heat dissipation fins away from the lens, and an exhaust fan on the side of the heat dissipation fins facing the lens, the intake fan draws in cool outside air into the searchlight body to dissipate heat from the searchlight body. The exhaust fan can expel hot air from inside the searchlight, accelerating the air circulation speed inside the searchlight body. The path of the air circulation inside the searchlight body can flow through the heat dissipation fins, carrying away the heat absorbed by the heat dissipation fins and enhancing the heat dissipation effect of the heat dissipation fins.

[0031] 3. On rainy days, rainwater can easily seep into the gap between the control device and the searchlight body. As the searchlight body rotates, rainwater will flow into the control device through the gap, causing a short circuit. By setting a vent at the top of the buffer housing, a ribbed buffer between the inner housing and the buffer housing, a drain hole at the extended end above the control device, and a seepage hole above the drain hole in the buffer, air can cool the top of the searchlight body through the vent at the top of the buffer housing. On rainy days, rainwater seeps into the space between the buffer housing and the inner housing through the vent, and then slowly leaks downwards along the outer circumference of the inner housing through the seepage holes on the buffer. During this seepage, the rainwater can lower the temperature of the inner housing, achieving a heat dissipation effect. The buffer above the control device guides the rainwater to the drain hole for discharge, preventing rainwater from seeping into the gap between the control device and the searchlight body, thus achieving a waterproof effect.

[0039] Therefore, it is necessary to provide an automated searchlight that can be stably oriented.

[0040] Please see Figure 1 , Figure 1 An automated searchlight provided in the first embodiment of this application includes a searchlight body 1, a control device 2, and a support base 3.

[0041] Please refer to the following: Figure 2 , Figure 2 The first embodiment of this application provides a cross-sectional view of an automated searchlight. The searchlight body 1 includes a housing 11, an illumination component 12, and a heat dissipation component 13. The housing 11 is made of a highly weather-resistant metal material, has good corrosion resistance, and can be used in outdoor environments for a long time. The outer casing 11 is cylindrical and has a lens 14 at one end. The outer casing 11 covers the lighting component 12 and the heat dissipation component 13. The heat dissipation component 13 is located at the rear of the outer casing 11, and the lighting component 12 is located on the side of the heat dissipation component 13 facing the lens 14. The control device 2 includes an elevation adjustment box 21 and a focus adjustment box 22 located on both sides of the outer casing 11. The focus adjustment box 22 can control the focusing motor, thereby controlling the focus of the searchlight. The elevation adjustment box 21 can adjust the pitch angle of the searchlight and fix the pitch angle of the searchlight body 1. The support base 3 includes a bracket 31 and a base 32. The bracket 31 is U-shaped and located at the bottom of the searchlight body 1. The two ends of the bracket 31 are connected to the focus adjustment box 22 and the elevation adjustment box 21, respectively, and the bottom of the bracket 31 is connected to the base 32.

[0042] Please refer to the following: Figure 3 , Figure 3 This is a schematic diagram of the internal structure of the elevation adjustment box. In this embodiment, the elevation adjustment box 21 includes a first drive motor 211, a first transmission worm gear 212, and a first transmission worm wheel 213 fixed to the searchlight body 1. A connecting piece is provided at the connection between the first transmission worm wheel 213 and the searchlight body 1, and the connecting piece is fixed to the searchlight body 1 by multiple bolts. After receiving a control signal, the first drive motor 211 starts operating, and its output shaft drives the first transmission worm gear 212 to rotate. Since the first transmission worm gear 212 and the first transmission worm wheel 213 mesh with each other, the rotation of the first transmission worm gear 212 will drive the first transmission worm wheel 213 to rotate accordingly. The first transmission worm wheel 213 is tightly fixed to the searchlight body 1, and the searchlight body 1 will rotate vertically under the drive of the first transmission worm wheel 213, achieving precise adjustment of the elevation angle. When it is necessary to fix the pitch angle of the searchlight body 1, simply stop the first drive motor 211. At this time, the first transmission worm 212 stops rotating. Due to the self-locking characteristic of the worm gear transmission, the first transmission worm wheel 213 also remains stationary. The searchlight body 1 will not rotate arbitrarily, thus ensuring the stability of the lighting direction of the automated searchlight.

[0043] Please refer to the following: Figure 4 , Figure 4 The diagram shows the internal structure of the base 32. The base 32 includes a second drive motor 321, a second transmission worm gear 322, and a second transmission worm wheel 323. The second drive motor 321 drives the second transmission worm gear 322 to rotate via a gear set 324. The gear set 324 includes two meshing gears, one of which is fitted onto the output shaft of the second drive motor 321, and the other gear is fitted onto one end of the second transmission worm gear 322. The second transmission worm gear 322 engages with the second transmission worm wheel 323, which has a rotating shaft fixed in its center. The second transmission worm wheel 323 is fixedly connected to the bottom of the bracket 31 via the rotating shaft. When the second drive motor 321 operates, power is transmitted to the second transmission worm gear 322 via the gear set 324, causing the second transmission worm gear 322 to rotate, which in turn drives the second transmission worm wheel 323 to rotate. This ultimately achieves horizontal rotation of the bracket 31 and the searchlight body 1, facilitating adjustment of the horizontal beam direction. Specifically, the second drive motor 321, the second transmission worm gear 322, and the second transmission worm wheel 323 are all located on the same plane parallel to the upper and lower surfaces of the base 32. This layout effectively reduces the height of the base 32, decreases the space it occupies during installation and use, and improves the overall adaptability of the searchlight.

[0044] In this embodiment, the heat dissipation assembly 13 includes heat dissipation fins 132 made of a metal material with high thermal conductivity and a cooling fan 131. The heat dissipation fins 132 extend radially towards the inner wall of the outer casing 11, enabling them to quickly absorb the heat emitted by the internal lighting assembly 12 of the searchlight. The cooling fan 131 is further divided into an intake fan 1311 and an exhaust fan 1312. The intake fan 1311 is located on the side of the heat dissipation fins 132 away from the lens 14, and the exhaust fan 1312 is located on the side of the heat dissipation fins 132 facing the lens 14. When the searchlight is working, the intake fan 1311 starts, drawing in cool air from the outside into the searchlight body 1. The cool air flows through the heat dissipation fins 132, carrying away the heat absorbed by the fins. Then, the exhaust fan 1312 exhausts the hot air from inside the searchlight after heat exchange. This cycle effectively enhances the heat dissipation effect and ensures that the internal temperature of the searchlight remains within a suitable range.

[0045] The working principle of this embodiment is as follows: By setting a worm gear driven by a motor and a worm gear fixed to the searchlight body 1 in the elevation adjustment box 21 and the base 32, the worm drives the worm gear to rotate, thereby realizing the automatic adjustment of the searchlight direction. Since the worm gear and the searchlight body 1 are in a fixed state, the searchlight body 1 and the worm gear will not wear or loosen due to rotation. Since the worm gear and the worm have a self-locking characteristic, when the worm is in a fixed state, the worm gear is also in a fixed state. Therefore, the illumination of the searchlight body 1 will not be arbitrarily deflected under the action of gravity. The operator can control the rotation of the motor through the control panel to achieve precise automatic adjustment.

[0046] Example 2

[0047] Please see Figures 5-6 , Figure 5This is a cross-sectional view of the searchlight body according to the second embodiment of this application. The structure of this embodiment is basically the same as that of the above embodiments, except that the outer shell 11 adopts a double-layer design, including an inner shell 111 and a buffer shell 112. The buffer shell 112 covers the inner shell 111, and the lighting component 12 and the heat dissipation fins 132 are both located inside the inner shell 111. Multiple buffer members 113 are fixed between the inner shell 111 and the buffer shell 112. The buffer members 113 are rib-shaped and extend to both ends of the searchlight body 1. They are fixed in an array on the outer peripheral surface of the inner shell 111, and the side facing away from the inner shell 111 is fixed to the inner wall of the buffer shell. The buffer members 113 are made of elastic metal and have a wavy cross-section. When the searchlight body 1 is accidentally hit, the inner shell 111 floats moderately inside the outer shell 11 through the buffer members 113, buffering the impact force generated by the collision and preventing the parts inside the inner shell 111 from being damaged by strong vibration. In this embodiment, the cooling fan 131 is located between the inner shell 111 and the buffer shell 112. The bottom of the inner shell 111 is provided with a vent hole 1111, so that the airflow guided by the cooling fan 131 can pass through the inner shell 111 and continue to circulate, ensuring that the heat dissipation effect is not affected.

[0048] In addition, the top of the buffer housing 112 is provided with a vent hole, and the extended end of the buffer member 113 located above the control device 2 is provided with a drain hole 114. The buffer member 113 located above the drain hole 114 is provided with a seepage hole 1131, which is located at the contact surface between the buffer member 113 and the inner housing 111. During use, air can cool the top of the searchlight body 1 through the vent hole at the top of the buffer housing; on rainy days, rainwater seeps into the space between the buffer housing 112 and the inner housing 111 through the vent hole, and the rainwater slowly leaks downward along the outer periphery of the inner housing 111 through the seepage hole 1131 on the buffer member 113. During the seepage process, the rainwater can reduce the temperature of the inner housing 111, achieving a heat dissipation effect. At the same time, the buffer member 113 located above the control device 2 guides the rainwater to the drain hole 114 for discharge, effectively preventing rainwater from seeping into the gap between the control device 2 and the searchlight body 1, thus achieving a waterproof effect.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
