Description

Technical Field

[0001] The invention relates to the technical field of police lights, and in particular to a multifunctional vehicle-mounted police light. Background Art

[0002] Vehicle-mounted police lights are lights installed on vehicles for warning and performing special tasks. When performing emergency tasks, such as chasing fugitives, handling emergencies, emergency rescue, etc., vehicle-mounted police lights can emit strong flashes and specific colors of light to warn other vehicles and pedestrians, allowing them to avoid them in time and ensure that the vehicles performing the task can pass through the road quickly and safely.

[0003] At present, a new type of vehicle-mounted warning laser light has appeared. When in use, this laser light can emit extremely bright light towards the sky and has a long irradiation distance, which can relieve fatigue for passing drivers. However, both traditional warning lights and new laser lights have certain defects. That is, in mountainous road environments, due to the complex environment on both sides of the road and the large number of obstructions, the warning distance of the warning light is subject to certain limitations and cannot play a good warning role. Summary of the invention

[0004] The purpose of the present invention is to provide a multifunctional vehicle-mounted police light, which solves the problem that the existing police lights in the background technology have a short warning distance in complex environments.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a multifunctional vehicle-mounted warning light, comprising a base and a shell slidably arranged above the base, and also comprising a warning light and a laser emitter movably arranged inside the shell, wherein a transparent window is arranged above the shell, the transparent window is annular, and the transparent window corresponds to the laser emitter, a motor is fixedly arranged below the base, a telescopic transmission rod is fixedly installed at the output end of the motor, the warning light comprises a rotating shaft and a rotating shell rotatably connected inside the shell, a circuit board is embedded and connected on the rotating shaft, the edge of the circuit board is fixedly connected to the inner wall of the rotating shell, an LED light is installed on the circuit board, and the motor is used to drive the warning light to rotate;

[0006] A rotating disk is fixedly installed on the upper part of the outside of the rotating shaft, and rotating components are evenly distributed on the outside of the rotating disk. The rotating disk is rotatably connected to the laser emitter through the rotating components. A swing component is arranged on the upper part of the inside of the shell. The swing component is used to change its angle when the laser emitter rotates. The swing component includes a gear ring fixedly connected to the inner wall of the top of the shell, and also includes a gear rotatably connected to the outside of the rotating disk and a guide block slidably connected to the outside of the rotating disk, wherein the gear is meshed with the gear ring, and a movable shaft for driving the guide block to move up and down is installed on the side of the gear, and a swing frame is movably installed between the guide block and the rotating component.

[0007] Furthermore, the telescopic transmission rod is a transmission component composed of multiple groups of slidingly connected sleeves, the cross-sectional shape of the sleeves is hexagonal, and the cross-sectional dimensions of the multiple groups of sleeves decrease from bottom to top.

[0008] Furthermore, the circuit board is provided with four groups of LED lights, and the four groups of LED lights are distributed in pairs on both sides of the circuit board, and the LED lights on both sides of the circuit board emit red light and blue light respectively.

When the motor drives the warning light and then drives the rotating disk to rotate, the rotating disk drives the laser emitter to rotate through the rotating assembly, and the gear engages with the gear ring to produce rotation during orbital rotation. When the gear ring rotates, the guide block is driven to reciprocate up and down under the action of the movable shaft and the guide block.

[0012] Furthermore, the rotating assembly includes a rotating frame fixedly connected to the outer wall of the rotating disk, the end of the rotating frame away from the rotating disk is rotatably connected to a mounting frame, the laser transmitter is embedded in the mounting frame, and the top of the mounting frame is also fixedly connected to a rotating shaft.

[0013] Furthermore, the two ends of the swing frame are respectively connected to the side of the guide block and the rotating shaft for rotation. When the guide block reciprocates up and down, the mounting frame is driven to swing around the rotating frame through the swing frame, thereby causing the laser emitter to swing while following the rotation of the rotating disk.

Under the action of the external thread and the nut seat, the shell is driven to rise upward from the inside of the base. When the motor rotates counterclockwise, the shell is retracted from the outside to the inside of the base, providing protection and reducing wind resistance.

[0015] Furthermore, the bottom and top of the rotating rod are respectively fixedly connected with a first limit plate and a second limit block, there is a gap between the first limit plate, the second limit block and the external thread, the top of the first limit plate and the bottom of the second limit block are respectively fixedly connected with a first spring and a second spring, when the shell moves to the maximum height, due to the gap between the second limit block and the external thread, the nut seat moves to the gap and no longer corresponds to the external thread, and the shell cannot continue to move at this time, and the motor drives the warning light and the laser emitter to rotate, and when the motor rotates counterclockwise, the rotating rod rotates under the reaction force of the second spring, the nut seat and the external thread can be smoothly combined, and the shell can be driven to descend.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The present invention provides a multifunctional vehicle-mounted warning light, which drives a warning light and a rotating disk to rotate during the rotation of a motor and a transmission rod. When the warning light rotates, red and blue lights flash. When the rotating disk rotates, a laser emitter is driven to rotate through a rotating component.

At the same time, under the action of a movable shaft and a guide shaft, the guide block moves up and down, and under the action of a swing frame, the mounting frame swings back and forth around the rotating frame. The laser emitter swings during the rotation process, thereby expanding the range of its laser emission. Compared with existing warning lights, its warning range is large, and the light beam emitted by the variable laser emitter can improve the anti-fatigue effect on passing drivers.

[0027] 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. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] In order to solve the technical problem that the existing warning lights have a small warning distance in complex environments, such as Figure 1-Figure 8 As shown, the following preferred technical solutions are provided:

[0029] like Figure 1-Figure 4As shown, a multifunctional vehicle-mounted warning light comprises a base 1 and a housing 2 slidably arranged on the upper part of the base 1, and also comprises a warning light 5 and a laser emitter 7 movably arranged inside the housing 2. A transparent window 21 is arranged on the upper part of the housing 2. The transparent window 21 is annular and corresponds to the laser emitter 7. A motor 3 is fixedly arranged at the lower part of the base 1, and a telescopic transmission rod 31 is fixedly installed at the output end of the motor 3. Figure 7-Figure 8 As shown, the warning light 5 includes a rotating shaft 51 and a rotating shell 54 which are rotatably connected to the inside of the housing 2. A circuit board 52 is embedded and connected to the rotating shaft 51. The edge of the circuit board 52 is fixedly connected to the inner wall of the rotating shell 54. An LED light 53 is installed on the circuit board 52. The motor 3 is used to drive the warning light 5 to rotate.

[0030] A rotating disk 6 is fixedly installed on the upper part of the outside of the rotating shaft 51, and rotating components 8 are evenly distributed on the outside of the rotating disk 6. The rotating disk 6 is rotatably connected to the laser emitter 7 through the rotating components 8. A swing component 9 is arranged on the upper part of the inside of the shell 2. The swing component 9 is used to change its angle when the laser emitter 7 rotates. The swing component 9 includes a gear ring 91 fixedly connected to the inner wall of the top of the shell 2, and also includes a gear 92 rotatably connected to the outside of the rotating disk 6 and a guide block 95 slidably connected to the outside of the rotating disk 6, wherein the gear 92 is meshed with the gear ring 91, and a movable shaft 921 for driving the guide block 95 to move up and down is installed on the side of the gear 92, and a swing frame 96 is movably installed between the guide block 95 and the rotating component 8.

[0031] like Figure 4 As shown, the telescopic transmission rod 31 is a transmission component composed of multiple sets of slidingly connected sleeves, the cross-sectional shape of the sleeves is hexagonal, and the cross-sectional dimensions of the multiple sets of sleeves decrease from bottom to top.

[0032] like Figure 7 As shown, there are four groups of LED lights 53 on the circuit board 52. The four groups of LED lights 53 are distributed in pairs on both sides of the circuit board 52. The LED lights 53 on both sides of the circuit board 52 emit red light and blue light respectively.

[0033] The rotating shell 54 is a transparent shell made of acrylic material, and the outer shell 2 is a shell made of polycarbonate.

[0034] like Figure 7-Figure 8As shown, a movable groove corresponding to the movable shaft 921 is provided on the guide block 95, and the movable groove is distributed laterally. The outer wall of the rotating disk 6 is fixedly connected with a fixed plate 93, and a guide shaft 94 is installed between the top of the fixed plate 93 and the guide block 95. The guide shaft 94 is a longitudinal guide component composed of a longitudinally distributed sleeve and a sliding rod slidably connected in the sleeve, wherein the sleeve is fixedly connected to the fixed plate 93, and the sliding rod is fixedly connected to the bottom of the guide block 95. The movable shaft 921 is fixedly connected to a position off-center on the side of the gear 92. When the motor 3 drives the warning light 5 and then drives the rotating disk 6 to rotate, the rotating disk 6 drives the laser emitter 7 to rotate through the rotating assembly 8. The gear 92 engages the gear ring 91 to rotate when it revolves. When the gear ring 91 rotates, the guide block 95 is driven to reciprocate up and down under the action of the movable shaft 921 and the guide block 95.

[0035] The rotating assembly 8 includes a rotating frame 81 fixedly connected to the outer wall of the rotating disk 6, and the end of the rotating frame 81 away from the rotating disk 6 is rotatably connected to the mounting frame 82, and the laser emitter 7 is embedded and installed on the mounting frame 82. The top of the mounting frame 82 is also fixedly connected to the rotating shaft 83. The two ends of the swing frame 96 are respectively rotatably connected to the side of the guide block 95 and the rotating shaft 83. When the guide block 95 reciprocates up and down, the mounting frame 82 is driven to swing around the rotating frame 81 through the swing frame 96, and then the laser emitter 7 is swung while following the rotation of the rotating disk 6. The laser line emitted by the laser emitter 7 passes through the transparent window 21 and shoots into the air, thereby increasing the emission range of its light and improving the warning effect.

[0036] like Figure 3-Figure 4 As shown, a telescopic assembly 4 is provided inside the base 1, and the telescopic assembly 4 is used to drive the housing 2 to retract into the inside of the base 1 or extend from the inside of the base 1 to the outside. The telescopic assembly 4 includes an active roller 41 fixedly installed on the outside of the telescopic transmission rod 31, and also includes a transmission roller 42 rotatably connected to the bottom of the inside of the base 1. The transmission roller 42 is provided with three groups, and a transmission belt 43 is installed between the three groups of transmission rollers 42 and the active roller 41. The top of the transmission roller 42 is fixedly connected to a rotating rod 44, and the middle outer part of the rotating rod 44 is provided with an external thread 45, and the surface of the external thread 45 A nut seat 46 is movably provided, and the nut seat 46 is fixedly connected to the outer lower part of the shell 2. A thread groove corresponding to the external thread 45 is provided in the middle of the nut seat 46. It is driven to rotate clockwise by the motor 3 and the telescopic transmission rod 31, and then the rotating rod 44 is driven to rotate clockwise under the action of the active roller 41, the transmission belt 43 and the transmission roller 42. Under the action of the external thread 45 and the nut seat 46, the shell 2 is driven to rise upward from the inside of the base 1. When the motor 3 rotates counterclockwise, the shell 2 retracts from the outside to the inside of the base 1, providing protection and reducing wind resistance.

[0037] The first limit plate 441 and the second limit block 443 are fixedly connected to the bottom and the top of the rotating rod 44 respectively. There is a gap between the first limit plate 441, the second limit block 443 and the external thread 45. The top of the first limit plate 441 and the bottom of the second limit block 443 are fixedly connected with the first spring 442 and the second spring 444 respectively. When the shell 2 moves to the maximum height, due to the gap between the second limit block 443 and the external thread 45, the nut seat 46 moves to the gap and no longer corresponds to the external thread 45. At this time, the shell 2 cannot continue to move, and the motor 3 drives the warning light 5 and the laser emitter 7 to rotate. When the motor 3 rotates counterclockwise, under the reaction force of the second spring 444, the rotating rod 44 rotates, and the nut seat 46 and the external thread 45 can be smoothly combined, which can drive the shell 2 to descend.

[0038] Specifically, the entire device is installed on the top of the police car. When in use, the motor 3 rotates clockwise, and the rotating rod 44 is driven to rotate through the telescopic transmission rod 31, the active roller 41, the transmission belt 43 and the transmission roller 42. The nut seat 46 moves upward under the action of the external thread 45, and then the entire shell 2 moves upward, and the telescopic transmission rod 31 extends and unfolds. During the rotation of the telescopic transmission rod 31, the warning light 5 and the rotating disk 6 are driven to rotate. When the warning light 5 rotates, the red and blue lights flash. When the rotating disk 6 rotates, the laser emitter 7 is driven to rotate through the rotating assembly 8. When the rotating disk 6 rotates, the gear 92 revolves. When the gear 92 revolves, it rotates under the meshing of the gear ring 91. At the same time, under the action of the movable shaft 921 and the guiding action of the guide shaft 94, the guide block 95 moves up and down, and under the action of the swing frame 96, the mounting frame 82 swings back and forth around the rotating frame 81. The laser emitter 7 swings during the rotation process, thereby expanding the range of its laser emission.
