Description

Technical Field

[0001] The present invention relates to the technical field of lighting vehicles, and in particular to a vehicle wing door opening control structure and a lighting vehicle. Background Art

[0002] Lighting vehicles are primarily used in emergency repair and rescue operations, providing lighting, power, and some emergency repair equipment. They can meet the sudden, scattered, and complex emergency rescue needs of power and communications departments. They can provide lighting and power when there is no electricity or power supply at the scene. Power is primarily provided by an onboard generator set, ensuring the normal operation of various equipment at the accident site. Equipped with a lifting lamp, they can provide high-power on-site illumination.

[0003] Lighting vehicles typically use a car chassis as a carrier for the carriage, which is a closed or semi-enclosed structure divided into a generator compartment, a control room, and an equipment compartment. A lighting panel is mounted on the end of a mast (typically 8 to 15 meters high). Wing doors (or hatches) are installed at the top opening of the carriage to cover or open the top opening and protect the mast and lighting fixtures inside.

[0004] Lighting vehicles often use a skylight-style roof as their roof opening and closing structure. This type of roof slides and opens, but requires space on the rooftop for stacking. Therefore, when the skylight is opened, the rooftop space is insufficient. This, when used on lighting vehicles, limits the specifications of the light fixtures and affects lighting performance.

[0005] Furthermore, the lamps are located near generators (a source of oil and dust), and during field operations, they are prone to accumulating diesel smoke, sand, and other dirt, which reduces light transmittance, leading to a decrease in lighting brightness and a reduction in illumination range. Manual cleaning requires significant manpower and time, resulting in low efficiency and limited timeliness. Therefore, the present invention provides a vehicle wing door opening control structure and a lighting vehicle.

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

[0022] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the invention, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0023] The technical solutions provided by various embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0024] Reference Figures 1 to 9 As shown, an embodiment of the present invention provides a vehicle wing door opening control structure, which is applied to a lighting vehicle. The lighting vehicle includes a chassis 1, and a carriage 2 is installed on the chassis 1.

[0025] Carriage 2 houses a generator compartment, a control room, and a power input / output compartment. The generator compartment, located in the middle of carriage 2, houses an 80kW diesel generator set that provides 380V / 220V power output, suitable for lighting systems, tools, and equipment, as well as external power supplies. The control room, located at the front of carriage 2, is equipped with a centralized control cabinet. The power input / output compartment, located at the rear of carriage 2, features 380V / 220V power output ports, copper busbar input / output ports, and an emergency input port, allowing for external power supply in the event of a generator failure.

[0026] Carriage 2 is a silent structure with a multi-layer structure. The outer layer is thick steel plate, and the inner layer is glass fiber sound-absorbing cotton for sound insulation and noise reduction, fiber cloth for moisture-proof, and mesh plate for ventilation. It can effectively control noise and meet the requirements of the working environment.

[0027] A flap door mechanism 3 is symmetrically mounted above the upper opening of the carriage 2, for opening and closing the top opening of the carriage 2. It comprises a main door panel 31 hingedly connected to the upper side of the carriage 2, with two retraction and extension assemblies 33 mounted between the main door panel 31 and the carriage 2. These assemblies 33 are used to rotate the main door panel 31 about its hinge point, allowing it to retract and extend.

[0028] Among them, 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 water-stopped by a maze-type structure, and an outward-convex guard edge (not marked in the figure) is provided on the top of the carriage 2. A sealing strip is provided on the surface of the guard edge, which contacts the main door panel 31 when it is closed, seals the joints, and improves the waterproof effect.

[0029] Specifically, the retractable and unfolding assembly 33 includes a mounting base 331 fixed to the carriage 2, and a hydraulic rod 332 is rotatably mounted on the mounting base 331. The telescopic end of the hydraulic rod 332 is rotatably connected to an L-shaped frame 333. The middle part of the L-shaped frame 333 is rotatably connected to the groove of the carriage 2 to form a fulcrum, and the outer end is rotatably sleeved with a connecting rod 334. The end of the connecting rod 334 away from the L-shaped frame 333 is rotatably connected to the main door panel 31.

[0030] The L-shaped frame 333 has a short arm part and a long arm part. The hydraulic rod 332 is connected to the short arm part 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 contracts, the short arm swings upward, pushing the L-shaped frame 333 to rotate around the middle fulcrum, and then drives the main door panel 31 to rotate through the connecting rod 334, thereby realizing stable retraction and extension of the main door panel 31.

[0031] The retractable and extendable assembly 33 is driven by multiple links to achieve a large-scale rotation of the main door panel 31 of 180 degrees, while also ensuring that the top of the carriage 2 is sufficiently open, with little restriction on the specifications of the lamp holder, thus ensuring lighting performance.

[0032] As one embodiment of the present invention, when the wing door structure is opened or closed 90°, the main door panel 31 is perpendicular to the top of the car body 2, forming a large windward surface perpendicular to the direction of the airflow. In crosswinds of level 5 or above, lateral thrust is easily generated, causing the car body to sway, posing a certain safety hazard. In this structure, the main door panel 31 can be flexibly adjusted within a range of 0° to 180°, fully expanding the space at the top of the car body 2. The main door panel 31 is flush with the top plane of the car body 2 or, through fine-tuning, forms a downward angle of less than 5°, transforming the windward surface into a flat structure parallel to the direction of the airflow. The airflow can flow smoothly over the door panel surface, reducing lateral thrust, thereby ensuring stable operation of the lighting vehicle.

[0033] An extension plate 32 is slidably mounted on the outer side of the main door panel 31 , and an extension assembly 34 is mounted 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 to expand the coverage range.

[0034] Specifically, the extension assembly 34 includes a motor 1 341 and two slide rails 345. The motor 1 341 is fixed to the main door panel 31, with a screw rod 342 fixedly connected to its output end. The outer end of the screw rod 342 is sleeved with a connecting seat 343, which is threadedly engaged with the connecting seat 343. A connecting plate 344 is fixed to one end of the connecting seat 343, and both sides of the connecting plate 344 are slidably connected to the slide rails 345 via sliders. A through slot 2 38 is defined in the middle of the main door panel 31, with the two slide rails 345 fixed to either side of the through slot 2 38. The connecting seat 343 extends through the through slot 38 and is fixed to the extension panel 32. When the motor 1 341 drives the screw rod 342 to rotate, the connecting seat 343 moves along the screw rod 342, driving the extension panel 32 to slide along the slide rails 345 via the connecting plate 344, thereby extending the extension panel 32.

[0035] The two symmetrical main door panels 31 can be flexibly rotated between 0° and 180° to meet different usage requirements. Extending the main door panels 31 180° not only reduces the windward area but also forms a shielding structure. Furthermore, the extension assembly 34 drives the extension panels 32 to extend, further expanding the shielding area on top of the carriage 2. This structure serves as a temporary rain shelter in rainy and snowy weather. Operators can perform operations such as lifting rod maintenance and lighting adjustment beneath the shelter to avoid direct rain splashing on equipment. Furthermore, the sheltered area can be used to temporarily store tools and spare parts, enhancing the convenience of field operations.

[0036] Among them, two pulleys 37 are rotatably connected to the lower end surface of the extension plate 32 through the wheel frame, and a through groove 35 is opened on both sides of the lower end surface of the main door panel 31, and a guide groove 36 is opened on both sides of the through groove 35. The pulley 37 passes through the through groove 35 and is slidably connected to the guide groove 36, which can reduce the friction when the extension plate 32 slides and improve stability.

[0037] An embodiment of the present invention further provides a lighting vehicle, comprising the above-mentioned vehicle wing door opening control structure, and also comprising a main lamp frame 4 and a cleaning mechanism 5.

[0038] The main light stand 4 is fixed inside the carriage 2 and provides primary lighting. It comprises an electric lift 41, with a rotatable rack 42 mounted on its upper end. Multiple floodlights 44 are fixed to the outer sides of the rack 42 at intervals. The electric lift 41 can move the rack 42 up and down to accommodate lighting needs at varying heights.

[0039] A cavity is provided at the upper end of the electric lifting rod 41, with an end plate 46 fixed inside. A motor three 47 is fixed to the lower end surface of the end plate 46, and a rotating seat 48 is rotatably connected to the upper end surface. The rotating seat 48 is fixed to the output end of the motor three 47, and the center of the disk rack 42 is fixed to the rotating seat 48. The motor three 47 drives the rotating seat 48 to rotate, which can drive the disk rack 42 to rotate at a maximum angle of 340°, thereby expanding the lighting range.

[0040] Mounting bracket 43 is mounted on the inside of floodlight 44, and angle adjustment assembly 45 is located on the outside of the mounting bracket 43 for adjusting the illumination angle of floodlight 44. Angle adjustment assembly 45 includes a second motor 451 fixed to one side of mounting bracket 43. The output end of motor 451 is fixedly connected to a first worm gear 452. Worm gear 452 is meshedly connected to a first worm gear 453 that is rotatably connected to mounting bracket 43. A rotating shaft 454 is rotatably connected to the lower side of mounting bracket 43. Floodlight 44 is fixed to the middle of rotating shaft 454, and worm gear 453 is fixed to rotating shaft 454.

[0041] Motor 2 451 drives worm 1 452, which in turn rotates worm gear 1 453 and shaft 454, thereby adjusting the pitch angle of floodlight 44. Combined with the raising and lowering of electric lift mast 41, the light can evenly cover a circular area, meeting the needs of scenarios such as road repairs and major accident scenes. For example, when inspecting equipment, the pitch angle can be adjusted to a small downward angle to focus the light on the work surface, such as mechanical interfaces and cable connectors, to avoid direct glare in the operator's eyes.

[0042] Among them, the worm 452 and the worm wheel 453 have mechanical self-locking properties when they are engaged. That is, after the drive stops, the worm wheel cannot drive the worm to rotate in the reverse direction, so the floodlight 44 can be stably locked at the target angle to prevent the angle from shifting due to vibration or wind during operation.

[0043] The lampshade of the floodlight 44 is prone to dust and oil accumulation during field operations, especially near the diesel generator set. If it is not cleaned for a long time, the light transmittance will decrease, seriously affecting the lighting brightness. Therefore, a cleaning mechanism 5 is fixedly installed inside the car 2 near the main lamp frame 4 for cleaning the lampshade of the floodlight 44.

[0044] The unit comprises a base 51, to which a fourth motor 54 is fixed. A turntable 52 is rotatably mounted on one side. A soft brush 53 is provided on the outer end of turntable 52, which contacts the lampshade of floodlight 44. A second worm 55 and a second worm gear 56 are rotatably connected on the other side of base 51. Worm 55 is fixed to the output end of motor 54, while worm gear 56 is fixed to the shaft end of turntable 52. Motor 54 drives worm 55, which in turn rotates worm gear 56 and turntable 52, causing soft brush 53 to wipe and clean the lampshade, ensuring brightness.

[0045] After the main lamp stand 4 completes its operation 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 .

[0046] The cleaning time of a single lamp can be controlled within 1 minute, which is divided into two stages: 30 seconds of forward rotation and 30 seconds of reverse rotation: during forward rotation, the turntable 52 drives the soft brush 53 to rotate clockwise along the outer side of the lampshade, and the soft brush 53 can quickly sweep away loose stains such as dust and sand on the surface; in the reverse stage, it rotates counterclockwise, using reverse friction to penetrate into the arc-shaped groove of the lampshade, removing stubborn stains that have not fallen off during forward rotation, forming a two-way cross-cleaning effect.

[0047] Because the lampshade of floodlight 44 is designed for wide-angle illumination, simply rotating the turntable 53 makes it difficult to cover the curved areas at the top and bottom of the lampshade. Therefore, during the cleaning process, the angle adjustment assembly 45 is synchronized: Motor 2 451 drives worm 1 452 and worm gear 1 453 to fine-tune the rotating shaft 454, causing the floodlight 44 to slowly tilt up and down within a small angle. This action creates dynamic contact between the curved surface of the lampshade and the soft brush 53. When the lampshade is tilted upward, the soft brush 53 conforms to its lower curvature; when tilted downward, it covers the upper curvature. Combined with the inherent elasticity of the soft brush 53, this ensures that every curved surface of the lampshade is fully contacted by the bristles, thus reducing blind spots during cleaning.

[0048] After the cleaning of a single lamp is completed, the motor 3 47 can be started to drive the rotating seat 48 to rotate, which can drive the disc rack 42 to rotate a certain angle, so that the next floodlight 44 enters the cleaning range of the cleaning mechanism 5 and is cleaned in turn, ensuring that each floodlight 44 can be fully cleaned, realizing automatic multi-lamp cleaning, and completing the cleaning operation of all floodlights 44 without manual intervention, with high efficiency and timeliness, which can adapt to the high requirements for equipment maintenance efficiency in field emergency operations.

[0049] It should be noted that there is sufficient space in the carriage 2 to allow the floodlight 44 to be rotated and adjusted at a small angle without interference.

[0050] A plurality of auxiliary lights 49 are installed at intervals on the inner side of the lower end surface of the rack 42. The light-emitting surface of the auxiliary lights 49 is tilted downward to supplement the lighting of the low-lying area around the carriage 2 and improve the comprehensiveness of the lighting.

[0051] The carriage 2 includes a carriage body 21, a partition 23 is fixed on the upper side of the interior of the carriage 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 divide the internal space of the carriage 2 into two functional areas: the upper lighting compartment and the lower equipment compartment.

[0052] Two auxiliary lamp stands 6 are also installed inside the carriage 2. The auxiliary lamp stands 6 include a lifting part and a lighting part. The lighting part runs through the partition 23 and can assist the main lamp stand 4 to expand the lighting range and adapt to complex scenes.

[0053] Among them, a double-layer sealing ring (not shown in the figure) can be installed in the opening of the partition 23. 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 penetrating upward into the lamp cabin, and at the same time prevent rainwater and dust in the lamp cabin from falling into the lower equipment area.

[0054] Two sets of spaced hydraulic support legs 22 are provided on both sides of the compartment 21, which are used to support the ground when the lighting vehicle is working and improve the overall stability; an inspection platform 24 is provided at the upper end of the rear side of the compartment 21, and a fence 25 is installed on the edge. A ladder 26 leading to the inspection platform 24 is fixed on the rear end face to facilitate the staff to inspect and maintain the top equipment. The fence 25 ensures the safety of inspection.

[0055] Working principle: After the lighting vehicle arrives at the work site, it first operates the hydraulic support legs 22 on both sides of the compartment 21 to unfold and support the ground to improve overall stability; then it starts the 80kW diesel generator set in the generator compartment in compartment 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.

[0056] The operator controls the wing door mechanism 3 to open in the control room: the hydraulic rod 332 of the retracting and extending component 33 is extended and retracted, pushing the L-shaped frame 333 to rotate around the central fulcrum, and driving the main door panel 31 to rotate from 0° to 180° through the connecting rod 334, so that it is flush with the top of the car 2 or forms a downward inclination angle within 5° to reduce the windward surface; if the environmental space environment permits, if the shielding area needs to be expanded, start the motor 341 of the extension component 34, drive the screw rod 342 to rotate, so that the connecting seat 343 moves along the screw rod 342, and is driven to extend along the slide rail 345 through the connecting plate 344. The pulley 37 at the lower end of the extension plate 32 slides in the guide groove 36 of the main door panel 31 to reduce friction, forming a temporary rain shelter, which is convenient for lifting rod maintenance, lamp debugging or tool placement below.

[0057] Then start the main lamp stand 4: 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 opened.

[0058] Specifically, an angle sensor is installed at the hinge point between the L-shaped frame 333 of the stowage assembly 33 and the carriage 2. This sensor collects real-time rotation angle data of the main door panels 31 and transmits it to the control room's PLC system. When the real-time angles of both sets of main door panels reach a threshold, the PLC determines "fully opened." If the angle of either set of main door panels falls below the threshold, the system issues an alarm and disables the door lift until the main door panels 31 are fully opened to a safe angle. At this point, the alarm is released and the door lift function resumes normal operation.

[0059] The electric lifting rod 41 rises, driving the disc frame 42 to rise to the required height; the motor three 47 drives the rotating seat 48 to rotate, so that the disc frame 42 rotates a maximum of 340° to adjust the lighting direction; the motor two 451 of the angle adjustment component 45 drives the worm one 452 to rotate, driving the worm gear one 453 and the rotating shaft 454 to rotate, adjusting the pitch angle of the floodlight 44, and coordinating with the lifting 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 car 2, and the auxiliary light frame 6 is simultaneously unfolded to improve the comprehensiveness of the lighting.

[0060] After the operation is completed, the extension plate 32 is retracted first: the motor 341 of the extension component 34 is reversed, and the screw rod 342 is driven to drive the extension plate 32 to retract along the slide rail 345 to the inner side of the main door panel 31 until the slider touches the limit switch at the end of the slide rail 345, and the "extension plate is retracted into place" signal is fed back.

[0061] Lower the main lamp stand 4 and the auxiliary lamp stand 6: start the descending program of the electric lifting rod 41, and completely retract the disc rack 42 and the floodlight 44 into the car 2; synchronously control the lifting part of the auxiliary lamp stand 6 to retract.

[0062] After confirming that the lamp stand is in place, the hydraulic rod 332 of the retracting and extending assembly 33 is retracted, driving the main door panel 31 to rotate from 180° to the 0° closed position through the L-shaped frame 333 and the connecting rod 334 until the door panel is closed in place, and finally retracting the hydraulic support leg 22.
