Description

Technical Field

[0001] This utility model relates to the field of vehicle lighting technology, specifically an intelligent lighting device for explosion-proof trackless rubber-wheeled vehicles. Background Technology

[0002] Explosion-proof trackless rubber-tired vehicles are trackless transport equipment designed specifically for flammable and explosive environments such as underground coal mines. They combine safety and mobility. Common explosion-proof trackless rubber-tired vehicles have a cargo compartment for the transfer of personnel and materials underground.

[0003] After the explosion-proof trackless rubber-tired vehicle transports personnel and materials to their destination underground, staff need to get off the vehicle or carry the materials. To facilitate the staff's observation and carrying work, the vehicle is usually equipped with fixed-brightness lighting to ensure basic lighting needs during vehicle operation.

[0004] However, due to the complex environment underground in coal mines and the presence of a large amount of coal dust, the lights are prone to being covered with thick layers of coal dust, causing the brightness of the lights to gradually decrease, which in turn reduces the lighting effect. Therefore, workers need to clean them frequently, which is time-consuming and laborious.

[0005] Therefore, an intelligent lighting device for explosion-proof trackless rubber-wheeled vehicles is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: An intelligent lighting device for explosion-proof trackless rubber-wheeled vehicles, comprising a reflector housing; an LED light is installed inside the reflector housing; a fixing ring is installed around the opening of the reflector housing; a lens is installed between the reflector housing and the fixing ring; a housing is fixedly connected through the center of the lens; a motor is installed inside the housing; a rotating base fixedly connected to the output shaft of the motor is installed in the center of the side of the housing away from the reflector housing; multiple crossbars are evenly arranged around the outer ring of the rotating base; a rubber scraper for scraping the lens is installed on the side of the crossbars near the lens.

[0008] Preferably, the housing has a plurality of locking blocks bolted around the side near the rotating base, and the locking blocks are rotatably connected to the rotating base.

[0009] Preferably, a fixed ring is fixedly connected to the inner ring of the fixed ring seat on the side away from the reflector housing; a sliding ring is rotatably mounted on the fixed ring; and the end of the crossbar away from the rotating seat is connected to the sliding ring.

[0010] Preferably, the sliding ring has a plurality of hinges for connecting the crossbar fixedly attached around the side away from the fixed ring.

[0011] Preferably, a U-shaped fixing block is fixedly connected to one end of the crossbar near the rotating seat; the U-shaped fixing block can be bolted to the rotating seat.

[0012] Preferably, a mounting plate is hinged to one end of the crossbar near the lens and the other end near the rotating base; the rubber scraper is mounted on the mounting plate, and a U-shaped spring is provided between the mounting plate and the crossbar.

[0013] Preferably, a sliding rod is fixedly connected inside the reflector housing; a movable frame is slidably mounted on the outer ring of the sliding rod; and the LED light is bolted to the movable frame.

[0014] The advantages of this utility model are:

[0015] 1. The present invention discloses an intelligent lighting device for an explosion-proof trackless rubber-wheeled vehicle, which comprises a motor, a rotating base, crossbars, and a rubber scraper. The motor drives the rotating base to rotate, which in turn drives multiple crossbars on the outer ring to rotate, causing the rubber scraper to rotate in contact with the lens and scrape off the coal dust on the lens surface, thereby ensuring the transparency of the lens and the lighting effect of the lighting device. At the same time, it avoids manual cleaning and reduces the difficulty of cleaning.

[0016] 2. The intelligent lighting device for explosion-proof trackless rubber-tired vehicles described in this utility model, through the arrangement of a reflective cover, lens, and housing, utilizes the conical structure of the reflective cover to achieve a focusing effect on the reflected light. The focused light illuminates the reflective surface at the chamfered corner of the housing, causing the focused light to diverge and reflect again. This reflection by the reflective cover ensures that the light passing through the lens is relatively parallel. After refraction by the lens, the illuminated light not only has a high-brightness area in the center but also a large illumination range, with a smooth transition between the center and the periphery. This effectively reduces the impact on the eyesight of workers. Furthermore, the divergent reflection of light at the chamfered corner of the housing effectively prevents the housing from blocking the light, thus avoiding dark areas in the illuminated area.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0032] like Figures 1 to 4 and Figures 10 to 12 As shown, an intelligent lighting device for an explosion-proof trackless rubber-wheeled vehicle includes a reflector housing 1; an LED light 2 is installed inside the reflector housing 1; a fixing ring seat 3 is provided on the outer ring of the opening of the reflector housing 1; a lens 4 is provided between the reflector housing 1 and the fixing ring seat 3; a housing 5 is fixedly connected through the middle of the lens 4; a motor 6 is installed inside the housing 5; a rotating seat 7 is provided on the middle of the side of the housing 5 away from the reflector housing 1, which is fixedly connected to the output shaft of the motor 6; a plurality of crossbars 8 are evenly arranged on the outer ring of the rotating seat 7; a rubber scraper 9 for scraping the lens 4 is provided on the side of the crossbars 8 near the lens 4.

[0033] In practice, the outer ring of the opening of the reflector housing 1 is threaded; the inner ring of the fixing ring 3 is threaded on the side near the reflector housing 1, and a protrusion is provided in the middle of the fixing ring 3; the outer diameter of the opening of the reflector housing 1 is the same as the diameter of the lens 4; the outer diameter of the opening of the reflector housing 1 and the diameter of the lens 4 are both matched with the inner ring diameter of the fixing ring 3, and are larger than the diameter of the protrusion in the middle of the fixing ring 3; the reflector housing 1 is installed into the inner ring of the fixing ring 3 by threads, and at the same time, the reflector housing 1 cooperates with the protrusion of the inner ring of the fixing ring 3 to clamp and fix the lens 4.

[0034] LED light 2 is a ring-shaped LED light strip that can be fixedly installed inside the reflector housing 1 by adhesive or bracket fixing, and the light direction of LED light 2 is towards lens 4;

[0035] The reflector housing 1 has a hole in the middle of the end away from the lens 4 for passing wires. The intrinsically safe power supply 103 on the explosion-proof trackless rubber-wheeled vehicle passes through the hole in the reflector housing 1 with wires to supply power to the LED light 2 and the motor 6 respectively.

[0036] Lens 4 has a convex structure, that is, the middle part protrudes from the outer periphery, like a convex mirror structure; a through hole is opened in the middle of lens 4, and the inner ring of the through hole is threaded; the outer ring of housing 5 is threaded to match the thread of the through hole of lens 4, housing 5 is installed into the through hole of lens 4 by means of thread, and a sealing strip is wound on the outer ring thread of housing 5, which can effectively prevent external coal dust from entering the interior of reflector housing 1.

[0037] The reflector housing 1 is conical, and its inner wall is reflective, which can reflect the light generated by the LED light 2. The housing 5 has a chamfer at one end near the reflector housing 1, and its outer wall is also reflective. Due to the conical structure of the reflector housing 1, the reflected light has a focusing effect. That is, the focused light will hit the reflective surface at the chamfer of the housing 5, and the focused light will be reflected again and reflected by the reflector housing 1. This makes the light passing through the lens 4 relatively parallel. After being refracted by the lens 4, the illuminated light not only has a high brightness area in the middle, but also a large illumination range. The brightness transition between the middle and the outer perimeter is relatively smooth, which can effectively reduce the impact on the eyesight of the staff. Furthermore, due to the divergent reflection of light at the chamfer of the housing 5, the housing 5 effectively avoids blocking the light, that is, it avoids the formation of a dark area in the middle of the illumination area due to the obstruction of the housing 5.

[0038] The outer ring of the fixing ring seat 3 can be fixed by a retaining ring and fixedly installed on the side wall of the explosion-proof trackless rubber-tired vehicle; and, a circular groove for installation can also be opened on the side wall of the explosion-proof trackless rubber-tired vehicle, that is, the depth of the circular groove is greater than the length of the combined reflector shell 1 and the fixing ring seat 3, and the diameter of the circular groove matches the diameter of the fixing ring seat 3. The fixing ring seat 3 and the circular groove are fixedly installed by bolts or sealant.

[0039] When the lighting device is in use, the LED light 2 emits light. Part of the light passes directly through the lens 4 and shines out, while part of the light is focused and reflected by the inner wall of the reflector 1 and shines on the reflective surface at the chamfer of the housing 5. The focused light is then dispersed and reflected again by the reflector 1, making the light passing through the lens 4 relatively parallel. This makes the brightness transition between the center and the periphery of the irradiated area smoother, effectively reducing the impact on the eyesight of the staff.

[0040] After the lighting device has been used for a certain period of time, coal dust will adhere to the surface of the lens 4. At this time, the controller controls the start motor 6 to rotate. The motor 6 drives the rotating base 7 to rotate, which in turn drives the multiple crossbars 8 on the outer ring to rotate, which in turn drives the rubber scraper 9 to rotate against the lens 4 and scrape off the coal dust on the surface of the lens 4. This ensures the transparency of the lens 4 and the lighting effect of the lighting device. At the same time, it avoids manual cleaning and reduces the difficulty of cleaning.

[0041] In this embodiment, the intelligent lighting device is equipped with a position sensor 101, which is located at the door of the explosion-proof trackless rubber-wheeled vehicle. When the door is closed, the door presses against the position sensor 101, causing the contact point of the position sensor 101 to open and the LED light 2 to turn off. When the door is opened, the reset spring inside the position sensor 101 resets, causing the contact point of the position sensor 101 to close and the LED light 2 to turn on. Thus, when the door is closed, the intelligent lighting device turns off; when the door is opened, the intelligent lighting device turns on. This facilitates the getting on and off of the vehicle and the handling of materials by the staff.

[0042] In this embodiment, the lighting control system of the intelligent lighting device includes a signal receiving module, a logic processing module, and a PWM pulse width modulation technology module 102. The signal receiving module receives the signal from the position sensor 101 and transmits the signal to the logic processing module to determine whether the door is open or closed, and controls the brightness of the LED light 2 through the PWM pulse width modulation technology module 102. That is, when the signal receiving module receives a door closing signal from the position sensor 101, it reduces the brightness of the LED light 2 through the PWM pulse width modulation technology module 102; when it receives a door opening signal, it increases the brightness of the LED light 2.

[0043] After the vehicle starts, the lighting control system turns on simultaneously. At this time, the doors are closed, and the contacts of the position sensor 101 are disconnected. The positive terminal of the vehicle's intrinsically safe power supply 103 is connected to the negative terminal of the intrinsically safe power supply 103 through the preset low-voltage interface of the LED light 2 and the PWM pulse width modulation technology module 102, forming a closed-loop circuit. Since the PWM pulse width modulation technology module 102 outputs a low duty cycle current at this time, the brightness of the LED light 2 is low to save energy and avoid driver glare.

[0044] When the carriage door is opened, the position sensor 101 is reset by the internal spring, causing the contact point to close. At this time, the lighting control system receives the door opening signal sent by the position sensor 101, and connects the high-voltage port or increases the duty cycle through the PWM pulse width adjustment technology module 102 to increase the current of the LED lamp 2, thereby increasing its brightness; so that people can quickly adapt to environmental changes and reduce the occurrence of accidents.

[0045] The principle of the PWM pulse width modulation technology module 102 is as follows: LED 2 flashes as the circuit switches on and off. When the switching frequency reaches a certain level, the brightness of LED 2 depends only on the average voltage at that frequency; that is, the higher the average voltage, the brighter LED 2. In this application, the first negative terminal 1021a of the PWM pulse width modulation technology module 102 is connected to the negative terminal of the intrinsically safe power supply 103, the second negative terminal 1021b is connected to the position sensor 101, and the positive terminal 1022 of the PWM pulse width modulation technology module 102 is connected to the positive terminal of the intrinsically safe power supply 103, and simultaneously connected in series with LED 2. When the position switch is open, current flows through the first negative terminal 1021a, and the PWM pulse width modulation technology module 102 controls the duty cycle of the voltage. When the position sensor 101 is closed, current flows through the second negative terminal 1021b, and at this time, the PWM pulse width modulation technology module 102 lowers the duty cycle of the voltage, thereby reducing the brightness of LED 2.

[0046] like Figures 3 to 5 As shown, a plurality of locking blocks 10 are bolted around the side of the housing 5 near the rotating base 7, and the locking blocks 10 can be rotatably connected to the rotating base 7;

[0047] In specific implementation, the outer ring of the rotary seat 7 is provided with an annular groove, and the side of the locking block 10 near the rotary seat 7 is provided with an arc-shaped protrusion that matches the inner wall of the annular groove. The arc-shaped protrusion of the locking block 10 is slidably disposed in the annular groove of the rotary seat 7. A stepped hole is provided in the middle of the locking block 10, and it is fixed to the housing 5 by screws.

[0048] As motor 6 drives rotary seat 7 to rotate, during long-term use, the fixation between rotary seat 7 and the output shaft of motor 6 may become loose, causing abnormal vibration of rotary seat 7, which in turn aggravates the loosening between rotary seat 7 and the output shaft of motor 6.

[0049] Therefore, by setting multiple locking blocks 10 evenly distributed around the rotating seat 7, the locking blocks 10 are fixed to the housing 5, and the arc-shaped protrusions of the locking blocks 10 slide in cooperation with the annular groove of the rotating seat 7, effectively limiting the position of the rotating seat 7, preventing the rotating seat 7 from shaking abnormally, thereby effectively preventing the rotating seat 7 from falling off, and improving the rotational stability of the rotating seat 7.

[0050] like Figure 2 , Figure 3 , Figures 6 to 7 As shown, a fixed ring 11 is fixedly connected to the inner ring of the fixed ring seat 3 on the side away from the reflector housing 1; a sliding ring 12 is rotatably mounted on the fixed ring 11; and the end of the crossbar 8 away from the rotating seat 7 is connected to the sliding ring 12.

[0051] In practice, the inner ring of the fixed ring seat 3 away from the reflector housing 1 has an annular mounting groove, and the fixed ring 11 is fixedly installed in the annular mounting groove by bolts; the surface of the fixed ring 11 that contacts the sliding ring 12 is provided with multiple balls to reduce friction.

[0052] When the rotating base 7 drives the multiple crossbars 8 of the outer ring to rotate, the multiple crossbars 8 drive the sliding ring 12 to rotate around the fixed ring 11. Through the cooperation of the sliding ring 12 and the fixed ring 11, the end of the crossbar 8 away from the rotating base 7 is supported and fixed, which effectively avoids the crossbar 8 from shaking under the centrifugal force of rotation, and avoids the crossbar 8 from hitting the lens 4 due to shaking. In addition, since the crossbar 8 can rotate stably, the rubber scraper 9 can also rotate, thereby improving the stability of the rubber scraper 9 in cleaning the lens 4.

[0053] like Figures 6 to 7 As shown, the sliding ring 12 has a plurality of hinges 14 for connecting the crossbar 8 fixedly connected around the side away from the fixed ring 11.

[0054] In specific implementation, the hinge 14 includes a fixed seat, a hinge shaft, a torsion spring, and a rotating seat; the fixed seat and the rotating seat are rotatably connected through the hinge shaft, the torsion spring is set on the outer ring of the hinge shaft, and the two ends of the torsion spring are respectively connected to the fixed seat and the rotating seat, so that the rotating seat can rotate back to a state perpendicular to the fixed seat under the elastic force of the torsion spring. The fixed seat is fixedly installed on the sliding ring 12 by bolts, and the rotating seat is fixedly connected to the end of the crossbar 8 away from the rotating seat 7 by bolts.

[0055] When cleaning the lens 4, the end of the crossbar 8 away from the hinge 14 is fixed to the rotating seat 7, so that the crossbar 8 is parallel to the lens 4, the hinge 14 is in the unfolded state, that is, the fixed seat and the rotating seat are in the unfolded state, and the torsion spring is in the stored state.

[0056] When it is necessary to clean or replace the rubber scraper 9, the crossbar 8 is separated from the rotating seat 7. At this time, the torsion spring of the hinge 14 is reset, causing the crossbar 8 to rotate to be perpendicular to the lens 4; thus facilitating the cleaning or replacement of the rubber scraper 9.

[0057] like Figure 5 , Figures 6 to 7 As shown, a U-shaped fixing block 15 is fixedly connected to one end of the crossbar 8 near the rotating seat 7; the U-shaped fixing block 15 can be bolted to the rotating seat 7;

[0058] In specific implementation, the outer ring of the rotary seat 7 is provided with a slot 16 that matches the U-shaped fixing block 15, so that the U-shaped fixing block 15 can be rotated and inserted into the slot 16; a screw that matches the inner side of the U-shaped fixing block 15 is fixedly connected inside the slot 16, and a nut is provided on the screw; at the same time, due to the U-shaped structure of the U-shaped fixing block 15, the screw will not affect the movement of the U-shaped fixing block 15.

[0059] When the rubber scraper 9 needs to be cleaned or replaced, turn the nut on the screw to release the U-shaped fixing block 15. At this time, the torsion spring of the hinge 14 is reset, which drives the crossbar 8 to rotate, so that the U-shaped fixing block 15 is disengaged from the groove 16.

[0060] After the rubber scraper 9 has been cleaned or replaced, press down the crossbar 8 so that the U-shaped fixing block 15 is inserted into the groove 16. Then, use the nut and screw to lock the U-shaped fixing block 15 in place; this further facilitates the cleaning or replacement of the rubber scraper 9.

[0061] like Figures 6 to 8 As shown, the end of the crossbar 8 near the lens 4 and the end near the rotating base 7 are hinged to the mounting plate 17; the rubber scraper 9 is mounted on the mounting plate 17, and a U-shaped spring 18 is provided between the mounting plate 17 and the crossbar 8;

[0062] In practice, the U-shaped spring 18 has a U-shaped structure and elastic force that expands on both sides; the two sides of the U-shaped spring 18 are fixedly installed to the mounting plate 17 and the crossbar 8 by screws respectively; the outer wall of the mounting plate 17 is provided with multiple guide grooves for installing the rubber scraper 9; the inner side of the rubber scraper 9 is provided with a protrusion that matches the guide groove of the mounting plate 17; during installation, the protrusion of the rubber scraper 9 is aligned with the guide groove on the mounting plate 17, and the rubber scraper 9 is pushed so that the rubber scraper 9 slides along the guide groove to install the rubber scraper 9 onto the mounting plate 17, which facilitates the replacement and installation of the rubber scraper 9;

[0063] The side of the rubber scraper 9 closest to the lens 4 has multiple scrapers; by setting the rubber scraper 9 into multiple scrapers, the surface of the lens 4 can be scraped multiple times, effectively improving cleaning efficiency and cleaning quality;

[0064] Because lens 4 is convex, the height of the outer ring of lens 4 is lower than the height of the middle part; therefore, the outer ring of lens 4 is difficult to scratch.

[0065] By utilizing the elastic force of the U-shaped spring 18, and with the hinge position of the mounting strip 17 close to the center of the lens 4, the mounting strip 17 tilts under the action of the U-shaped spring 18, causing the end of the mounting strip 17 close to the outer ring of the lens 4 and also close to the surface of the lens 4. This allows the rubber scraper 9 to fully contact the surface of the lens 4, thereby ensuring the thorough cleaning of the lens 4.

[0066] like Figure 2 and Figure 9 As shown, a sliding rod 19 is fixedly connected inside the reflector housing 1; a movable frame 20 is slidably mounted on the outer ring of the sliding rod 19; and the LED light 2 is bolted to the movable frame 20.

[0067] In practice, one end of the slide rod 19 is fixed to the inner wall of the reflector housing 1 away from the lens 4, and the other end contacts the outer wall of the housing 5, which not only restricts the position of the housing 5, but also improves the stability of the slide rod 19.

[0068] The middle part of the movable frame 20 is a sliding ring that can slide along the slide rod 19 and can be locked and fixed by screws; the outer side of the movable frame 20 is a radially arranged mounting rod, and the mounting rod has a straight slot; the LED light 2 is fixed by bolts passing through the straight slot on the mounting rod;

[0069] The position of the LED light 2 is controlled by sliding the movable frame 20 along the slide bar 19, thereby controlling the illumination range of the LED light 2; the LED light 2 is installed by bolts passing through the straight slot on the movable frame 20, which not only facilitates the replacement of the LED light 2, but also facilitates the installation of LED lights 2 of different specifications.

[0070] Working principle: When the lighting device is in use, the LED light 2 emits light. Part of the light passes directly through the lens 4 and shines out, while part of the light is focused and reflected by the inner wall of the reflector 1 and shines on the reflective surface at the chamfer of the housing 5. The focused light is then dispersed and reflected again by the reflector 1, making the light passing through the lens 4 relatively parallel. This makes the brightness transition between the center and the periphery of the irradiated area smoother, effectively reducing the impact on the eyesight of the staff.

[0071] After the lighting device has been used for a certain period of time, coal dust will be attached to the surface of the lens 4. At this time, the controller will start the motor 6. The motor 6 will drive the rotating base 7 to rotate, drive the multiple crossbars 8 of the outer ring to rotate, and drive the mounting strip 17 and the rubber scraper 9 to rotate.

[0072] Due to the elastic force of the U-shaped spring 18, and the fact that the hinge position of the mounting strip 17 is close to the middle of the lens 4, the mounting strip 17 tilts under the elastic force of the U-shaped spring 18, so that the end of the mounting strip 17 that is close to the outer ring of the lens 4 is also close to the surface of the lens 4, so that the rubber scraper 9 can fully contact the surface of the lens 4 and scrape off the coal powder on the surface of the lens 4.

[0073] When the rubber scraper 9 needs cleaning or replacement, turn the nut on the screw to release the U-shaped fixing block 15. At this time, the torsion spring of the hinge 14 returns to its original position, causing the crossbar 8 to rotate perpendicular to the lens 4. Simultaneously, the U-shaped fixing block 15 disengages from the slot 16. After the rubber scraper 9 has been cleaned or replaced, press down the crossbar 8 to make the U-shaped fixing block 15 snap into the slot 16. At the same time, due to the U-shaped structure of the U-shaped fixing block 15, the screw will not affect the movement of the U-shaped fixing block 15. Then, use the nut in conjunction with the screw to lock the U-shaped fixing block 15 in place. This facilitates the cleaning or replacement of the rubber scraper 9.

[0074] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
