Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of vehicle lighting, and particularly relates to an intelligent multi-axis dimming vehicle-mounted lighting lamp. Background Art
[0002] The auxiliary lighting lamp of an off-road vehicle is a dedicated lighting system designed to cope with complex road conditions. It usually uses high-brightness LEDs or halogen light sources, has the characteristics of waterproof, shockproof and corrosion resistance, and is suitable for harsh environments. Its core functions include providing wilderness lighting with long-distance spotlights (such as strip lights, spotlights), enhancing the penetration power in rainy and foggy weather with wide-angle fog lights, and assisting in judging the terrain at night with positioning disk lights.
[0003] There are obvious deficiencies in the current vehicle-mounted lighting system in terms of functionality and lighting effects. Most traditional lighting lamps adopt a fixed installation structure, and can only achieve limited angle adjustment through simple mechanical buckles, and the adjustment process needs to be completed with the help of tools, and it is impossible to adjust the irradiation direction in real time according to the road conditions during driving. More prominently, the existing systems generally adopt a single light source lighting mode. Due to the overly concentrated light source distribution, problems such as lighting blind spots and uneven light distribution are likely to occur. Especially under complex terrain conditions, it is difficult for a single light source to achieve an all-round and dead-angle-free lighting effect.
[0004] To solve the above problems, the present invention proposes an intelligent multi-axis dimming vehicle-mounted lighting lamp. Summary of the Invention
[0005] To solve the problems in the background art, the present invention proposes an intelligent multi-axis dimming vehicle-mounted lighting lamp.

[0007] It also includes a system control unit, which includes a first circuit board and a second circuit board. The first circuit board controls the rotating motor through the control port CH0, and the control ports CH1-CH3 respectively control the 1-3 axis drive motors. The reading end DI0-DI3 receives the 1-4 axis origin signal, and the reading end DI4-DI7 corresponds to the horizontal left / right turn and vertical down / up instructions respectively; the second circuit board controls the 4-7 axis drive motors through the control port CH0-CH3, and the reading end DI0-DI3 receives the 5-8 axis origin signal, and the reading end DI6-DI7 corresponds to the car left / right turn instruction.
[0008] The present invention is further configured such that the transmission assembly includes a worm and a worm wheel, the worm is fixedly mounted on the output shaft of the driving motor, the worm wheel is rotatably mounted inside the support frame below the corresponding lighting lamp, and the worm and the worm wheel are meshingly connected.
[0009] The present invention is further configured such that a fixing ring is fixedly installed at a position corresponding to the lighting lamp on the support frame, and the fixing ring is rotationally matched with the bottom end of the lighting lamp; the worm gear passes through the fixing ring and the two form a rotational fit, and the top end of the worm gear is fixedly connected to the bottom end of the lighting lamp.
[0010] The present invention is further configured such that a reduction gearbox is fixedly installed at a position corresponding to the worm inside the support frame, and rotating bearings are installed on both sides of the reduction gearbox. The output shaft of the drive motor and the end of the worm gear away from the drive motor are respectively matched with the internal limiting rotation of the two rotating bearings.
[0011] The present invention is further configured such that a positioning plate is rotatably mounted on the bottom end of the worm wheel, a photoelectric switch is fixedly mounted on the side wall of the reduction box, a photoelectric detection slot is provided on the photoelectric switch, and the positioning plate is fixedly arranged inside the photoelectric detection slot.
[0012] The present invention is further configured such that the system control unit is fixedly arranged between two adjacent reduction gearboxes corresponding to the inner top surface of the support frame, and the system control unit is one or more.
[0013] The present invention is further configured such that the signal from the reading end DI6 / reading end DI7 triggers the steering control when it lasts for more than 0.20s, resets 2.0s after the signal stops, and activates the fine-tuning function of the reading end DI4-reading end DI7 when the driving motor returns to its position and there is no steering instruction.
[0014] The present invention is further configured such that when there is no input at the reading terminal DI6 and the reading terminal DI7 and after the driving motor returns to the origin, the motor can be fine-tuned according to the reading terminal DI4-reading terminal DI7 as a manual operation.
[0015] Compared with the prior art, the present invention has the following beneficial effects:
[0016] 1. The on-vehicle intelligent multi-axis dimming lighting lamp, by setting a rotary motor, a lighting lamp, a driving motor, a worm, a worm gear, a reduction gearbox, a fixing ring, a rotating bearing and a system control unit, and an 8-channel linkage control system of a first circuit board and a second circuit board, ensures that 7 lighting lamps achieve synchronous deflection in the horizontal plane or the vertical plane, improving the dimming accuracy and response speed. It is applicable to the night operations of special vehicles, can intelligently adapt to the lighting requirements of complex terrains, achieve dead-angle-free lighting in scenarios such as emergency rescue and engineering operations, and effectively improve the operation safety and efficiency.
[0017] 2. The on-vehicle intelligent multi-axis dimming lighting lamp adopts a three-stage transmission chain composed of a worm, a worm gear and a fixing ring, in cooperation with a rotating bearing, a fastening hole and a fastening pin. The worm is driven by a driving motor to rotate, and after being decelerated by the worm gear pair, it is transmitted to the lighting lamp without clearance through the fixing ring. After the fastening screw is screwed into the fastening hole, its end parts respectively press against the plane and the outer diameter surface of the driving end of the worm, forming a three-point mechanical locking structure - the vertical pressure of the screw on the plane generates axial constraint, and the radial pressure on the outer diameter surface eliminates the fitting clearance. The dual effects ensure zero backlash in power transmission. This connection method breakthroughly cancels the traditional coupling structure, improves the internal space utilization rate of the reduction gearbox, reduces the overall axial dimension, and at the same time improves the assembly convenience. Moreover, it reduces the axial runout and radial runout, meeting the requirements of precision transmission.
[0018] 3. The on-vehicle intelligent multi-axis dimming lighting lamp is equipped with a worm gear driven by a worm, an optoelectronic origin return component (the position is detected by the notch between the positioning disk and the optoelectronic switch) and a mechanical origin return component (the arc-shaped limit chute of the fixing ring cooperates with the zero-return pin of the lighting lamp). The action process is divided into an optoelectronic mode and a mechanical mode: during normal operation, the optoelectronic switch realizes origin positioning by detecting the notch of the positioning disk; when the optoelectronics fails, the system automatically switches to the mechanical mode, and the driving motor makes the lighting lamp accurately return to the midpoint origin through the hard limit cooperation between the zero-return pin and the chute. The dual origin return design not only ensures the real-time performance of high-precision optoelectronic positioning, but also ensures the reliable reset of the system in case of sensor failure through mechanical redundancy, significantly improving the fault resistance and operation stability of the equipment.
[0019] 4. The on-vehicle intelligent multi-axis dimming lighting lamp has a through hole opened at the bottom end of the worm gear, and the through hole extends upward to the bottom end of the lighting lamp. A power cord is fixedly connected to the bottom end of the lighting lamp, and the power cord is connected to the power supply through the through hole. The power cord is completely built inside the support frame, which not only avoids the mess of external wiring and improves the overall aesthetics, but also effectively prevents the power cord from being worn, pulled or corroded by the environment due to exposure, enhancing the reliability and service life of the circuit.

Detailed implementation manners
[0030] It should be noted that, without conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the drawings and in combination with the embodiments.
[0031] It should be pointed out that, unless otherwise specified, all technical and scientific terms used in the present application have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present application belongs.
[0032] In the present invention, unless otherwise stated, the orientations such as "upper, lower" are usually in the directions shown in the drawings, or in the vertical, perpendicular or gravitational directions; similarly, for ease of understanding and description, "left, right" are usually in the left and right shown in the drawings; "inside, outside" refer to the inside and outside relative to the contours of each component itself, but the above orientation terms are not used to limit the present invention.
[0033] Please refer to Figures 1-5The present invention provides a technical solution: a vehicle-mounted intelligent multi-axis dimming lighting lamp, including a mechanical module, the mechanical module includes a support frame 1, both ends of the support frame 1 are provided with side panels 2, the bottom ends of the side panels 2 are fixedly connected with assembly plates 3, and the characteristics are: a rotating motor 4 for driving the support frame 1 to rotate vertically is installed on the side panel 2, and the output shaft of the rotating motor 4 is fixedly connected to the end of the support frame 1; the assembly plate 3 provides a reliable installation interface, and the rotating motor 4 is started. The output shaft of the rotating motor 4 rotates to drive the support frame 1 to rotate as a whole. The rotating motor 4 realizes the overall angle adjustment of the support frame 1, thereby expanding the lighting range.
[0034] A plurality of illuminating lamps 5 are rotatably mounted on the upper end surface of the support frame 1 , a driving motor 6 for driving the illuminating lamps 5 to rotate horizontally is fixedly mounted inside the support frame 1 , and a transmission assembly is disposed between the driving motor 6 and the corresponding illuminating lamps 5 .
[0035] The transmission assembly includes a worm 7, a worm wheel 8, a reduction box 9 and a rotating bearing 11. The worm 7, the worm wheel 8, the reduction box 9, the rotating bearing 11 and the support frame 1 are integratedly installed to reduce space occupancy; the worm 7 is limited and fixed on the output shaft of the drive motor 6, and the worm wheel 8 is rotatably installed at the bottom of the support frame 1, and the worm 7 is meshed and connected with the worm wheel 8; the worm gear transmission structure has a self-locking characteristic, which can accurately control the steering angle of the lighting lamp 5, while providing a larger reduction ratio to enhance the dimming stability.
[0036] The reduction box 9 adopts a bilaterally symmetrical layout, with rotating bearings 11 installed on both side walls. The output shaft of the driving motor 6 and the non-driving end of the worm 7 are respectively embedded in the inner rings of the rotating bearings 11 on both sides by interference fit, forming a highly coaxial rotating support structure. A fixing ring 10 is configured at the installation position of each lighting lamp 5 on the support frame 1. The fixing ring 10 and the bottom end of the lighting lamp 5 are connected in a rotational manner with a clearance fit. At the same time, the worm wheel 8 penetrates the fixing ring 10 and forms a rotational fit with it through the bearing. The top end of the worm wheel 8 is rigidly connected to the bottom end of the lighting lamp 5 to build a complete power transmission chain.
[0037] The innovative connection scheme between the drive motor 6 and the worm 7 adopts a plug-in matching structure: the output shaft of the drive motor 6 directly meshes with the drive end of the worm 7 through the plug-in surface, and two fastening holes 20 are symmetrically opened on the outer circumference of the output shaft, and their positions strictly correspond to the plane and outer diameter surface of the worm drive end; during assembly, after the two high-strength fastening screws are screwed into the fastening holes 20, their ends respectively press against the plane and outer diameter surface of the worm drive end to form a three-point mechanical locking structure - the vertical pressure of the screws on the plane produces axial constraints, and the radial pressure on the outer diameter surface eliminates the matching clearance, and the dual action ensures zero backlash in power transmission. This connection method has made a breakthrough in eliminating the traditional coupling structure, improving the internal space utilization of the reduction box 9, reducing the overall axial size, and improving the convenience of assembly. It also reduces the axial movement and radial runout to meet the requirements of precision transmission.
[0038] Inside the support frame 1, a reduction gearbox 9 is provided at the assembly position of the worm 7. An optoelectronic origin return component is arranged between the reduction gearbox 9 and the worm gear 8; the optoelectronic origin return component includes a positioning disk 12 and an optoelectronic switch 13; the positioning disk 12 is rotatably installed at the bottom end of the worm gear 8, and a notch 18 is formed at the edge of the positioning disk 12; the optoelectronic switch 13 is fixedly installed on the side wall of the reduction gearbox 9, and an optoelectronic detection groove 14 is formed on the optoelectronic switch 13. The positioning disk 12 is placed in the optoelectronic detection groove 14, and the position detection is realized through the cooperation of the optoelectronic switch 13 and the notch 18.
[0039] When the notch 18 aligns with the optoelectronic detection groove 14: the light passes through the notch 18, and the receiving tube detects the light, triggering a change in the trigger level. When the solid part blocks the detection groove: the light is blocked, the receiving tube has no signal, and the level is restored. The system determines the position of the notch 18 by detecting the level jump, thereby judging the mechanical origin of the worm gear 8. The optoelectronic switch 13 outputs an electrical signal by detecting the change in the light-passing state of the notch 18, providing the position reference of the worm gear 8 for the control system, and realizing the origin return or position synchronization function.
[0040] A mechanical origin return component is arranged between the fixing ring 10 and the lighting lamp 5. The mechanical origin return component serves as a redundant backup for the optoelectronic origin return component and is enabled when the optoelectronic switch 13 fails. When the optoelectronic origin return function is abnormal, when the system detects that the solid part of the positioning disk 12 passes through the optoelectronic detection groove 14, the optoelectronic switch 13 still continuously outputs a detection signal (normally the solid part should block the light to interrupt the signal). At this time, the system determines that the optoelectronic switch 13 is damaged and automatically switches to the mechanical origin return mode.
[0041] The mechanical origin return component consists of an arc-shaped limit chute 16 and a zeroing pin 17. Among them, an arc-shaped limit chute 16 with a range of 180° is machined on the lower end surface of the fixing ring 10, and the zeroing pin 17 is fixedly installed at the bottom end of the lighting lamp 5. The zeroing pin 17 forms a sliding fit with the arc-shaped limit chute 16. When the worm gear 8 rotates driven by the driving motor 6, the lighting lamp 5 rotates synchronously and drives the zeroing pin 17 to slide along the arc-shaped limit chute 16. When it is necessary to return the lighting lamp 5 to the mechanical origin, the driving motor 6 first rotates in the reverse direction, and through the transmission of the worm gear 8, the zeroing pin 17 moves towards one end of the arc-shaped limit chute 16 until the zeroing pin 17 abuts against the end of the chute; then the driving motor 6 rotates forward by 90°, driving the worm gear 8 and the lighting lamp 5 to swing back, so that the zeroing pin 17 is accurately positioned at the midpoint position of the arc-shaped limit chute 16. At this time, the lighting lamp 5 is at the preset mechanical origin, and the return action is completed.
[0042] Please refer to Figure 5, in the embodiment of the present invention: a through hole 19 is provided at the bottom end of the worm wheel 8, and the through hole 19 extends upward to the bottom end of the lighting lamp 5. A power cord is fixedly connected to the bottom end of the lighting lamp 5, and the power cord is connected to the power supply through the through hole 19. This structural design completely internalizes the power cord within the support frame 1, not only avoiding the clutter of external wiring and improving the overall aesthetics, but also effectively preventing the wear, pulling or environmental corrosion of the power cord due to exposure, enhancing the reliability and service life of the circuit. In addition, the hidden wiring reduces the interference risk of moving parts, ensuring that the rotation movements of the worm wheel 8 and the lighting lamp 5 are smoother and more stable, and further improving the overall protection level and operating safety of the device.
[0043] Please refer to Figure 8 , in the embodiment of the present invention: an aluminum heat sink 22 with heat dissipation fins is fixedly installed at the rear side of the lighting lamp 5, and a spoiler 21 with an inclination angle of 30° is rigidly connected to its top. The curved surface of the spoiler 21 can efficiently direct the oncoming air flow to the fin gaps of the heat sink 22 when the vehicle is moving, forming forced convection heat dissipation.
[0044] Please refer to Figures 6-7 , the system control unit 15 is fixedly arranged between two adjacent speed reducers 9 corresponding to the inner top surface of the support frame 1, and the system control unit 15 is one or more. The system control unit 15 is used to control the rotation motor 4 and the drive motor 6 to work independently or cooperatively.
[0045] Specifically, the system control unit 15 is composed of a first circuit board and a second circuit board. Among them, the control port CH0 channel of the first circuit board is dedicated to controlling the rotation motor 4, and the control port CH1 - control port CH3 channels independently drive the 1 - 3 axis drive motors 6 respectively. At the same time, its reading ends DI0 - reading end DI3 interfaces real - time monitor the origin positioning signals of the 1 - 4 axes, and the reading ends DI4 - reading end DI7 interfaces are respectively defined as the directional movement control instructions for horizontal left turn, horizontal right turn, vertical descent and vertical ascent; the control port CH0 - control port CH3 channels of the second circuit board respectively correspond to the drive control of the 4 - 7 axis drive motors 6, the reading ends DI0 - reading end DI3 interfaces are responsible for collecting the origin signals of the 5 - 8 axes, and the reading ends DI6 - reading end DI7 interfaces are specifically used for vehicle steering control, where the reading end DI6 triggers the left - turn instruction and the reading end DI7 triggers the right - turn instruction.
[0046] The system control unit 15 incorporates intelligent control logic. When it detects that the input signals of reading terminal DI6 or reading terminal DI7 continuously exceed 0.20 s, it automatically activates the corresponding steering control program to ensure the precise execution of the steering action. After the steering signal terminates, the system delays for 2.0 s to execute the reset action to eliminate the influence of mechanical inertia and restore to the initial state. In addition, when all the 1st - 7th shafts of the drive motor set are in the homing state and there is no signal at the steering instruction reading terminals DI6 / DI7, the system automatically enables the fine - tuning function of the reading terminals DI4 - DI7 channels, allowing position calibration in the horizontal and vertical directions through short - pulse signals.
[0047] Working principle:
[0048] The working principle of this system is based on mechatronic collaborative control: The system control unit 15 drives the rotation motor 4 through the CH0 channel of the first circuit board control port to adjust the overall orientation of the support frame 1. At the same time, it controls the 1st - 3rd shaft drive motors 6 through the CH1 - CH3 channels of the control port respectively, and cooperates with the 4th - 7th shaft drive motors 6 controlled by the CH0 - CH3 channels of the second circuit board control port to form an 8 - axis linkage control system.
[0049] When the reading terminals DI6 / DI7 interface receives a valid steering instruction signal, the system control unit 15 starts to output the PWM duty cycle through PID regulation, so that each drive motor 6 runs synchronously according to the preset acceleration curve. After the instruction terminates, the system automatically enters a 2.0 - second damping deceleration stage to ensure smooth reset. When the drive motor set (multiple drive motors 6) completes the origin positioning and there is no steering instruction, the reading terminals DI4 - DI7 channels switch to the fine - tuning mode. At this time, the system control unit 15 realizes the manual fine - tuning of the lighting angle.
[0050] The mechanical transmission link adopts three - stage motion transmission: The output shaft of the drive motor 6 drives the worm 7 to rotate at a rated speed through key connection, and transmits the motion without clearance to the lighting lamp 5 through the worm - gear pair and the rigid fixing ring 10.
[0051] The entire transmission chain is equipped with dual - positioning guarantees: The angular contact bearings in the reduction gearbox 9 reduce the axial run - out, and the flange - type positioning disk 12 at the bottom of the worm gear cooperates with the photoelectric switch 13 to achieve radial positioning, reducing the position synchronization error of multi - axis dimming. During system operation, the encoder real - time feeds back the position information of each axis. The system control unit 15 dynamically adjusts the output torque of each motor through RS485 serial communication to ensure that the 8 lighting units achieve synchronous deflection at the milliradian level in the horizontal plane.
[0052] In the embodiment of the present invention: reduction boxes 9 are fixedly installed inside the support frame 1 corresponding to the positions of the worm gears 7. Rotating bearings 11 are assembled on both sides of the reduction boxes 9. The output shaft of the drive motor 6 and one end of the worm gear 7 away from the drive motor 6 are respectively in limited rotational fit with the inside of the two rotating bearings 11. The combined structure of the reduction box 9 and the rotating bearing 11 ensures the coaxiality when the worm gear 7 rotates, reduces mechanical wear, and extends the service life.
[0053] In the embodiment of the present invention: a positioning disk 12 is rotatably installed at the bottom end of the worm wheel 8. A photoelectric switch 13 is fixedly installed on the side wall of the reduction box 9. A photoelectric detection groove 14 is formed on the photoelectric switch 13. The positioning disk 12 is fixedly arranged inside the photoelectric detection groove 14. A double limiting structure is formed, effectively suppressing the axial movement and radial swing of the worm wheel 8, and greatly improving the transmission accuracy.
[0054] In the embodiment of the present invention: a system control unit 15 is installed between adjacent reduction boxes 9 on the inner top surface of the support frame 1 through positioning rod bolts. The bottom sides of the relative ends of the two reduction boxes 9 are respectively bolted to both sides of the system control unit 15. The overall structural rigidity is enhanced, preventing displacement of each transmission component due to vibration, and ensuring the synchronism of multi-axis light regulation.
[0055] The above has described the embodiments of the present invention in detail with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the knowledge scope of those of ordinary skill in the art in the said technical field, various changes can also be made without departing from the purpose of the present invention.
