Description

Technical Field

[0001] This invention relates to the field of lighting vehicle technology, and more particularly to a wing-door opening control structure and a lighting vehicle. Background Technology

[0002] The lighting vehicle is mainly used in emergency repair and disaster relief operations, providing lighting and power guarantees, as well as some repair and disaster relief equipment. It can meet the emergency rescue needs of power, communications, and other departments in the face of sudden, dispersed, and complex accidents. It can provide lighting and power supply in situations where there is no power or normal power supply is unavailable. Power is primarily provided by an onboard generator set, ensuring the normal operation of various equipment at the accident site. The equipped lifting lights can provide high-power on-site lighting for the rescue scene.

[0003] Lighting vehicles typically use a car chassis to support a cargo box, which is a closed or semi-closed structure, internally divided into a generator compartment, control room, and equipment compartment. A boom (usually 8-15 meters high) is used, with light fixtures mounted at the top. A wing door (or hatch) is installed at the top opening of the cargo box to cover or open the top opening, protecting the boom and lighting fixtures inside.

[0004] The roof opening structure of lighting vehicles often adopts a sunroof type. However, the sunroof type uses a sliding and pushing mechanism to open and close. But the roof needs to reserve space for stacking the roof, so the open space on the roof of the vehicle is not sufficient after the sunroof type is opened. When applied to lighting vehicles, this will limit the specifications of the lamp holders and affect the lighting performance.

[0005] Furthermore, the lamps are located near the generator set (a source of oil and dust), and during field operations, they easily accumulate diesel fumes, sand, and other dirt, which reduces light transmittance, leading to decreased lighting brightness and a reduced illumination range. Manual cleaning requires significant manpower and time, is inefficient, and lacks timeliness. Therefore, this invention provides a wing-door opening control structure and a lighting vehicle.

[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present application concept, and therefore may include information that does not constitute technology. Summary of the Invention

[0015] The cleaning mechanism, which is fixed inside the carriage, includes a motor four. A turntable is rotatably mounted on one side of the motor four. A soft brush is provided on the outer end face of the turntable. The soft brush contacts the lamp cover of the mounting bracket. The turntable is driven by the motor four, which is fixed to the base.

[0016] Furthermore, the upper end of the electric lifting rod is provided with a cavity and an end plate is fixed inside the cavity. A motor is fixed to the lower end face of the end plate, and a rotating seat is rotatably connected to the upper end face of the end plate and fixedly connected to the output end of the motor.

[0043] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0044] The technical solutions provided by the various embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0045] Reference Figures 1 to 9 As shown, this embodiment of the invention provides a wing-shaped door opening control structure, applied to a lighting vehicle. The lighting vehicle includes a chassis 1, on which a cargo box 2 is mounted.

[0046] Carriage 2 contains a generator compartment, a control room, and a power input / output compartment. The generator compartment is located in the middle of carriage 2 and houses an 80kW diesel generator set, providing 380V / 220V power output to meet the needs of lighting systems, tools, equipment, and external power supply. The control room is located at the front of carriage 2 and is equipped with a centralized control cabinet. The power input / output compartment is located at the rear of carriage 2 and has 380V / 220V power output ports, copper busbar input / output ports, and an emergency input port, allowing for external power supply in case of generator failure.

[0047] Carriage 2 is a silent structure with a multi-layer structure. The outer layer is a thick steel plate, and inside are glass fiber sound-absorbing cotton for sound insulation and noise reduction, fiber cloth for moisture protection, and perforated plate for ventilation. It can effectively control noise and meet the requirements of the working environment.

[0048] A wing door mechanism 3 is symmetrically installed at the opening on the top of the carriage 2 for opening or closing the opening. It includes a main door panel 31 that is hinged to the upper side of the carriage 2. Two retractable components 33 are installed between the main door panel 31 and the carriage 2. The retractable components 33 are used to drive the main door panel 31 to rotate around the hinge point to realize the retraction and extension.

[0049] The main door panel 31 adopts a double-layer waterproof design, with an outer steel plate and an inner rubber sealing strip. The joints are sealed with a labyrinth structure. The top of the carriage 2 is equipped with a protruding edge (not shown in the figure). The surface of the edge is equipped with a sealing strip, which contacts the main door panel 31 when it is closed to seal the joints and improve the waterproof effect.

[0050] Specifically, the retractable assembly 33 includes a mounting base 331 fixed to the carriage 2. A hydraulic rod 332 is rotatably mounted on the mounting base 331. An L-shaped frame 333 is rotatably connected to the telescopic end of the hydraulic rod 332. The middle part of the L-shaped frame 333 is rotatably connected to the groove of the carriage 2 to form a fulcrum. A connecting rod 334 is rotatably sleeved on the outer end. The end of the connecting rod 334 away from the L-shaped frame 333 is rotatably connected to the main door panel 31.

[0051] The L-shaped frame 333 has a short arm and a long arm. The hydraulic rod 332 is connected to the short arm of the L-shaped frame 333. When the hydraulic rod 332 extends, its telescopic end pushes the short arm of the L-shaped frame 333 to swing downward. When the hydraulic rod 332 retracts, the short arm swings upward, pushing the L-shaped frame 333 to rotate around the central fulcrum. This, in turn, drives the main door panel 31 to rotate through the connecting rod 334, thus achieving stable opening and closing of the main door panel 31.

[0052] The retraction component 33, through multi-link linkage, enables the main door panel 31 to rotate 180°, while also ensuring sufficient open area at the top of the carriage 2. This minimizes restrictions on the specifications of the light fixtures and ensures lighting performance.

[0053] In one embodiment of the present invention, when the wing door structure is opened or closed at 90°, the main door panel 31 is perpendicular to the top of the carriage 2, forming a large-area windward surface perpendicular to the airflow direction. Under crosswinds of level 5 or above, this can easily generate lateral thrust, causing the vehicle body to sway and posing a certain safety hazard. In this structure, the main door panel 31 can be flexibly adjusted within the range of 0° to 180°, allowing the top space of the carriage 2 to be fully expanded. The main door panel 31 is flush with the top plane of the carriage 2 or can be adjusted to form a downward tilt angle of less than 5°. The windward surface is transformed into a flat structure parallel to the airflow direction, allowing the airflow to flow smoothly over the door panel surface with less lateral thrust, thereby ensuring the stable operation of the lighting vehicle.

[0054] An extension plate 32 is slidably installed on the outer side of the main door panel 31, and an extension assembly 34 is installed on the inner side of the main door panel 31. The extension assembly 34 is used to drive the extension plate 32 to slide out along the main door panel 31 and expand the coverage area.

[0055] Specifically, the extension assembly 34 includes a motor 341 and two slide rails 345. The motor 341 is fixed to the main door panel 31, and a lead screw 342 is fixedly connected to its output end. A connecting seat 343 is sleeved on the outer end of the lead screw 342, and the lead screw 342 and the connecting seat 343 are threaded together. A connecting plate 344 is fixed to one end of the connecting seat 343, and the two sides of the connecting plate 344 are slidably connected to the slide rails 345 via sliders. A through groove 38 is provided in the middle of the main door panel 31, and the two slide rails 345 are fixed on both sides of the through groove 38. The connecting seat 343 passes through the through groove 38 and is fixed to the extension plate 32. When the motor 341 drives the lead screw 342 to rotate, the connecting seat 343 moves along the lead screw 342, and the extension plate 32 slides along the slide rails 345 through the connecting plate 344, thereby achieving extension.

[0056] Two sets of symmetrical main door panels 31 can rotate flexibly within a range of 0° to 180° to meet different usage needs. When the main door panels 31 are unfolded to 180°, they not only reduce the windward area but also form a shielding structure. In addition, with the extension assembly 34 driving the extension plate 32 to extend, the shielding area can be further expanded on the top of the carriage 2. This structure can serve as a temporary rain shelter in rainy or snowy weather. Operators can perform tasks such as maintenance of the lifting rod and adjustment of lights under the rain shelter, avoiding direct splashing of rainwater on the equipment. At the same time, the sheltered area can be used to temporarily place tools, spare parts, etc., improving the convenience of field operations.

[0057] The lower end face of the extension plate 32 is connected to two pulleys 37 by a wheel frame. The lower end face of the main door plate 31 is provided with a through groove 35 on both sides, and a guide groove 36 is provided on both sides of the through groove 35. The pulleys 37 pass through the through groove 35 and are slidably connected to the guide groove 36, which can reduce the friction when the extension plate 32 slides and improve stability.

[0058] This invention also provides a lighting vehicle, including the aforementioned wing door opening control structure, as well as a main lamp holder 4 and a cleaning mechanism 5.

[0059] The main light fixture 4 is fixed inside the carriage 2 to provide main lighting. It includes an electric lifting rod 41, with a rotatable frame 42 mounted on the upper end of the electric lifting rod 41. Multiple floodlights 44 are fixed at intervals on the outer side of the frame 42. The electric lifting rod 41 can drive the frame 42 to rise and fall, adapting to different lighting needs at different heights.

[0060] The upper end of the electric lifting rod 41 is provided with a cavity, and an end plate 46 is fixed inside. A motor 47 is fixed to the lower end face of the end plate 46, and a rotating seat 48 is rotatably connected to the upper end face. The rotating seat 48 is fixed to the output end of the motor 47. The center of the plate frame 42 is fixed to the rotating seat 48. The motor 47 drives the rotating seat 48 to rotate, which can drive the plate frame 42 to rotate at a maximum angle of 340°, thus expanding the lighting range.

[0061] A mounting bracket 43 is installed on the inner side of the floodlight 44, and an angle adjustment component 45 is provided on the outer side for adjusting the illumination angle of the floodlight 44. The angle adjustment component 45 includes a second motor 451 fixed to one side of the mounting bracket 43. A worm gear 452 is fixedly connected to the output end of the second motor 451. The worm gear 452 is engaged with a worm wheel 453 that is rotatably connected to the mounting bracket 43. A rotating shaft 454 is rotatably connected to the lower side of the mounting bracket 43. The floodlight 44 is fixed in the middle of the rotating shaft 454, and the worm wheel 453 is fixed to the rotating shaft 454.

[0062] Motor 2 451 drives worm gear 1 452 to rotate, which in turn drives worm wheel 1 453 and shaft 454 to rotate, thereby adjusting the pitch angle of floodlight 44. In conjunction with the raising and lowering of electric lifting mast 41, the light can evenly cover a circular area, meeting the needs of scenarios such as road repair and large-scale accident scenes. For example, during equipment maintenance, the pitch angle can be adjusted to a small downward angle, focusing the light on the work surface, such as mechanical interfaces and cable joints, avoiding direct glare to the operator's eyes.

[0063] When the worm gear 452 and the worm wheel 453 mesh, they have mechanical self-locking properties. That is, after the drive stops, the worm wheel cannot drive the worm gear to rotate in the opposite direction. This can stably lock the floodlight 44 at the target angle and prevent the angle from shifting due to vibration or wind during operation.

[0064] The lens of the floodlight 44 is prone to accumulating dust and oil during field operations, especially near the diesel generator set. If it is not cleaned for a long time, the light transmittance will decrease, which will seriously affect the lighting brightness. Therefore, a cleaning mechanism 5 is fixedly installed inside the carriage 2 near the main light frame 4 to clean the lens of the floodlight 44.

[0065] It includes a base 51, on which a motor 54 is fixed. A turntable 52 is rotatably mounted on one side, and a soft brush 53 is provided on the outer end face of the turntable 52, which contacts the lampshade of the floodlight 44. On the other side of the base 51, a worm gear 55 and a worm wheel 56 are rotatably connected, meshing with each other. The worm gear 55 is fixed to the output end of the motor 54, and the worm wheel 56 is fixed to the shaft end of the turntable 52. The motor 54 drives the worm gear 55 to rotate, which in turn drives the worm wheel 56 and the turntable 52 to rotate, causing the soft brush 53 to wipe and clean the lampshade, ensuring the lighting brightness.

[0066] After the main light fixture 4 completes its work and is retracted into the carriage 2, the cleaning process of the cleaning mechanism 5 can be started through the integrated panel in the control room inside the carriage 2.

[0067] The cleaning time for a single lamp can be controlled within 1 minute, divided into two stages: 30 seconds in the forward direction and 30 seconds in the reverse direction. In the forward direction, the turntable 52 drives the soft brush 53 to rotate clockwise along the outside of the lampshade, and the soft brush 53 can quickly sweep away loose dirt such as floating dust and sand particles on the surface. In the reverse direction, it rotates counterclockwise and uses the reverse friction to penetrate into the arc-shaped groove of the lampshade to remove stubborn dirt that was not removed in the forward direction, forming a two-way cross cleaning effect.

[0068] Because the lampshade of the floodlight 44 is an arc shape designed for wide-angle lighting, simply relying on the rotation of the turntable 53 is insufficient to cover the arc-shaped areas at the top and bottom of the lampshade. Therefore, during the cleaning process, the angle adjustment component 45 is activated simultaneously: motor 2 451 drives worm gear 1 452 and worm wheel 1 453 to fine-tune the rotating shaft 454, causing the floodlight 44 to slowly adjust its tilt within a small angle range. This action creates dynamic contact between the arc-shaped surface of the lampshade and the soft brush 53. When the lampshade tilts upward, the soft brush 53 conforms to its lower arc; when tilted downward, it covers the upper arc. Combined with the elasticity of the soft brush 53 itself, this ensures that all curved surfaces of the lampshade can fully contact the bristles, thereby reducing cleaning dead spots.

[0069] After a single light is cleaned, motor 3 47 can be started to drive the rotating seat 48 to rotate, which can drive the plate frame 42 to rotate at a certain angle, so that the next floodlight 44 enters the cleaning range of the cleaning mechanism 5 for sequential cleaning, ensuring that each floodlight 44 can be fully cleaned. This achieves automated multi-light cleaning, which can complete the cleaning of all floodlights 44 without manual intervention. It is highly efficient and timely, and can meet the high requirements for equipment maintenance efficiency in field emergency operations.

[0070] It should be noted that there is ample space inside carriage 2, allowing the floodlights 44 to rotate and be adjusted at small angles without causing any interference.

[0071] Multiple auxiliary lights 49 are installed at intervals on the inner side of the lower end face of the frame 42. The light-emitting surface of the auxiliary lights 49 is tilted downward, which can supplement the low-level area around the carriage 2 and improve the overall lighting.

[0072] The carriage 2 includes a body 21. A partition 23 is fixed to the upper side of the interior of the body 21. The upper end of the electric lifting rod 41 passes through the partition 23, and the lower end of the base 51 is fixed to the partition 23. The partition 23 is used to separate the interior space of the carriage 2 into two functional areas: an upper lighting compartment and a lower equipment compartment.

[0073] The interior of carriage 2 is also equipped with two auxiliary light frames 6. The auxiliary light frame 6 includes a lifting part and a lighting part. The lighting part runs through the partition 23 and can assist the main light frame 4 to expand the lighting range and adapt to complex scenes.

[0074] The partition 23 can be fitted with a double-layer sealing ring (not shown in the figure). Preferably, the inner layer can be made of nitrile rubber to prevent oil, and the outer layer can be made of fluororubber to prevent water. This can prevent oil and water vapor in the generator compartment from seeping upward into the lamp compartment, and at the same time prevent rainwater and dust in the lamp compartment from falling into the lower equipment area.

[0075] Two sets of spaced hydraulic support legs 22 are provided on both sides of the body 21 to support the ground when the lighting vehicle is working, thereby improving the overall stability. A maintenance platform 24 is provided at the upper rear side of the body 21, and a fence 25 is installed on the edge. A ladder 26 leading to the maintenance platform 24 is fixed on the rear end face, which facilitates the maintenance of the equipment on the top by the staff. The fence 25 ensures the safety of maintenance.

[0076] Working principle: After the lighting vehicle arrives at the work site, it first operates the hydraulic support legs 22 on both sides of the body 21 to unfold and support the ground, improving overall stability; then it starts the 80kW diesel generator set in the generator compartment inside the body 2 to provide 380V / 220V power. If the generator fails, it connects to external power through the power input and output compartment to power the entire system.

[0077] Operators control the wing door mechanism 3 from the control room to open it: the hydraulic rod 332 of the extension assembly 33 extends and retracts, pushing the L-shaped frame 333 to rotate around the central fulcrum, and through the connecting rod 334, it drives the main door plate 31 to rotate from 0° to 180°, making it flush with the top of the carriage 2 or forming a downward tilt angle of less than 5° to reduce the windward surface; if the environmental space permits, if it is necessary to expand the shelter area, the motor 341 of the extension assembly 34 is started, driving the lead screw 342 to rotate, so that the connecting seat 343 moves along the lead screw 342, and through the connecting plate 344, it extends along the slide rail 345. The pulley 37 at the lower end of the extension plate 32 slides in the guide groove 36 of the main door plate 31 to reduce friction, forming a temporary rain shelter, which facilitates the maintenance of the lifting rod, the debugging of lights, or the placement of tools below.

[0078] Next, the main light frame 4 is started: Before the electric lifting rod 41 starts the lifting program, the system will automatically trigger the main door panel 31 opening status detection process to avoid interference and collision between the electric lifting rod 41 and the main door panel 31 that is not fully open.

[0079] Specifically, an angle sensor is installed at the hinge point between the L-shaped frame 333 of the retraction assembly 33 and the carriage 2 to collect the rotation angle data of the main door panel 31 in real time and transmit it to the PLC system in the control room. When the real-time angle of both main door panels reaches the threshold range, the PLC determines that the door is "open in place". If the angle of either main door panel does not reach the threshold, the system alarms and prohibits the lifting of the mast until the main door panel 31 is fully opened to a safe angle. At this point, the alarm is deactivated and the mast lifting function returns to normal.

[0080] The electric lifting rod 41 rises, driving the plate frame 42 to the required height; the motor 3 47 drives the rotating seat 48 to rotate, so that the plate frame 42 rotates a maximum of 340° to adjust the lighting direction; the motor 2 451 of the angle adjustment component 45 drives the worm gear 1 452 to rotate, driving the worm wheel 1 453 and the rotating shaft 454 to rotate, adjusting the tilt angle of the floodlight 44, and coordinating with the raising and lowering of the electric lifting rod 41 to make the light evenly cover the target area (such as focusing on the work surface or covering a large area), the auxiliary light 49 tilts downward to supplement the low-level lighting around the carriage 2, and the auxiliary light frame 6 unfolds simultaneously to improve the overall lighting.

[0081] After the operation is completed, the extension plate 32 is retracted first: the motor 341 of the extension assembly 34 reverses, driving the lead screw 342 to retract the extension plate 32 along the slide rail 345 back to the inside of the main door panel 31 until the slider touches the limit switch at the end of the slide rail 345, and a "extension plate retracted in place" signal is fed back.

[0082] Lower the main lamp holder 4 and the auxiliary lamp holder 6: Initiate the lowering procedure of the electric lifting rod 41 to completely retract the panel 42 and floodlight 44 into the carriage 2; Simultaneously control the retraction of the lifting part of the auxiliary lamp holder 6.
