Description

Technical Field

[0001] The present invention relates to the technical field related to automobile lamps, and in particular to a new energy electric vehicle lamp with an infrared sensing function. Background Art

[0002] New energy electric vehicle headlights with infrared sensing functions combine infrared sensing technology, intelligent lighting systems and adaptive control algorithms. They can detect pedestrians, vehicles and obstacles through infrared sensors at night, in foggy or low-visibility environments, and intelligently adjust the beam range, illumination angle and brightness to provide a clearer field of view, reduce driving blind spots, and improve driving safety. At the same time, they can also be linked with advanced driver assistance systems to achieve hazard warnings, active obstacle avoidance and automatic high and low beam switching, further enhancing the vehicle's intelligent driving experience, so that drivers can also obtain efficient and safe lighting support in complex road environments. Moreover, with the development of laser infrared, AI recognition and vehicle networking technologies, this type of headlights are evolving towards a more precise, energy-saving and intelligent direction, providing new energy electric vehicles with a higher level of safety protection and a high-tech lighting solution.

[0003] While infrared sensing lights equipped with new energy electric vehicles can improve visibility and driving safety during nighttime driving, they still pose certain safety risks in special road conditions. For example, on arch bridges, the rising and falling road surface gradient causes the vehicle's headlight projection angle to change accordingly. When the vehicle reaches the top of the arch, the front of the vehicle is relatively elevated, and the light's direction of illumination rises accordingly, causing the high beam to shine directly forward or even upward. This not only fails to effectively illuminate the road ahead, but can also cause strong glare to oncoming drivers, affecting their vision and increasing the risk of accidents. When the vehicle descends the arch, the light's projection angle gradually returns to normal, but a brief period of beam deviation can still create blind spots, making it difficult for the driver to detect obstacles or pedestrians on the road ahead.

[0004] In addition, when driving at night on U-shaped sunken sections of road, such as underpasses, tunnels or low-lying areas, the vehicle's headlights have a relatively low projection angle, and the illumination range is therefore limited. Since the lights are almost close to the ground, the visible range in the distance is reduced, making it difficult for the road environment ahead to be fully illuminated. Especially in the absence of street lights or in low light conditions, the driver's field of vision is significantly limited. This situation may affect the prediction of emergencies, such as obstacles, pedestrians or vehicles suddenly appearing ahead, increasing the risk of potential traffic accidents.

[0040] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0041] Example: Figure 1-10 As shown, the present invention provides a new energy electric vehicle headlight with an infrared sensing function, including a lamp frame 1 fixed to the front of the new energy electric vehicle, and also includes: an intelligent low beam lamp group 4 electrically connected to the control system of the new energy electric vehicle, and the intelligent low beam lamp group 4 is fixedly installed in the lamp frame 1; it also includes a self-balancing infrared sensing component 8, and the self-balancing infrared sensing component 8 is rotatably installed in the lamp frame 1, wherein the self-balancing infrared sensing component 8 includes multiple infrared sensors, and the multiple infrared sensors cooperate to monitor the angle between the vehicle surface and the ground in real time, and feed back to the control system, and the control system receives the monitoring information and controls the intelligent low beam lamp group 4 to adjust the real-time angle of the intelligent low beam lamp group 4.

[0042] The above-mentioned new energy electric vehicle headlight with infrared sensing function dynamically adjusts the illumination angle through the coordinated action of the self-balancing infrared sensing component 8 and the intelligent low-beam light group 4 to adapt to the changes in the vehicle body posture under different road environments, ensuring optimal lighting effects and reducing safety hazards. Among them, the self-balancing infrared sensing component 8 is always perpendicular to the direction of gravity under the influence of gravity. Regardless of whether the vehicle is traveling on an arch bridge, a U-shaped sunken section or other sloped road section, it can accurately sense the changes in the angle between the vehicle body and the ground;

[0043] When a vehicle enters an arch bridge, the illumination direction of ordinary headlights will rise with the angle of the vehicle body, causing the lights to be high and possibly directly hitting the field of vision of the oncoming vehicle driver. At this time, the infrared sensor of the system detects that the illumination distance is shortened and immediately feeds back data to the control system. The control system then adjusts the angle of the intelligent low beam group 4 to shift the light beam downward to ensure that the light is accurately projected on the road surface, thereby reducing glare interference to oncoming drivers and improving driving safety. When the vehicle enters a U-shaped sunken section, the light beam of conventional headlights will be overly concentrated on the nearby road due to the downward tilt of the vehicle head, resulting in limited vision in the distance. At this time, the infrared sensor of the system detects that the illumination distance is lengthened and feeds back to the control system. The control system then controls The intelligent low beam group 4 adjusts its angle upward to expand the distant lighting range, ensuring that the driver can promptly detect obstacles or pedestrians ahead, and improving driving safety at night and in complex road environments. At the same time, the system's self-balancing infrared sensing component 8 adopts a gravity-adaptive structure, which can always maintain a monitoring reference parallel to the ground without the need for additional energy drive, making the infrared sensor measurement more accurate, and the real-time angle adjustment mechanism of the intelligent low beam group 4 ensures that the light distribution always meets driving needs. Regardless of whether the vehicle is in complex road conditions such as uphill, downhill, bridges, tunnels, etc., it can provide stable, uniform and safe lighting effects, thereby greatly improving the driving safety and driving experience of new energy electric vehicles at night and in special sections.

[0044] The front of the lamp frame 1 is snap-fitted with a lampshade 2, and the position of the intelligent low-beam lamp group 4 in the lamp frame 1 is snap-fitted with a transparent protective cover 5. The upper part of the lamp frame 1 is also fixedly mounted with a high-beam lamp 3, which is electrically connected to the control system.

[0045] A lampshade 2 is snap-fitted onto the front of the lamp frame 1 to protect the internal components of the lamp from external dust, moisture and debris, while ensuring the uniformity and stability of light transmission; a transparent protective cover 5 is installed at the position of the intelligent low beam lamp group 4 to prevent external damage and ensure that the light is not blocked, thereby improving the lighting effect; a high beam lamp 3 is fixedly installed on the upper part of the lamp frame 1 and is electrically connected to the control system so that it can be automatically turned on or off according to road conditions, thereby improving nighttime driving safety and ensuring that the high and low beam lamps work in coordination to achieve more precise road lighting.

[0046] Among them, the infrared sensor includes a first infrared sensor 802 and a second infrared sensor 803, and the first infrared sensor 802 and the second infrared sensor 803 are fixedly installed on the base 801 in the lamp frame 1. Among them, the angle between the first infrared sensor 802 and the ground is greater than the angle between the second infrared sensor 803 and the ground, and the angle between the first infrared sensor 802 and the ground is less than 90 degrees.

[0047] The infrared sensor includes a first infrared sensor 802 and a second infrared sensor 803, which are fixed on a rotatable base 801. Accurate vehicle posture monitoring is achieved through angle difference. The angle of the first infrared sensor 802 is greater than that of the second infrared sensor 803, ensuring that it can monitor ground changes in a wider range. The angle of the first infrared sensor 802 is less than 90 degrees, so that it is always facing the ground, improving detection accuracy, thereby optimizing the adjustment of the headlight illumination angle and ensuring lighting adaptability in different slope environments.

[0048] A counterweight 804 is also installed at the rear of the base 801 for self-balancing the base 801. The counterweight 804 includes a magnetic shell 8041. There are multiple magnetic shells 8041, one side of which is fixedly connected to a stud 8044. One of the magnetic shells 8041 is screwed to the side of the base 801 away from the first infrared sensor 802 via the stud 8044. The rear magnetic shell 8041 is screwed to the front magnetic shell 8041. Several iron blocks 8042 are magnetically attached to the rear of the magnetic shell 8041. The magnetic shell 8041 has a through hole 8043 that penetrates the plug-in cavity of the iron block 8042. When removing the iron block 8042, an iron rod extends through the through hole 8043 into the plug-in cavity of the iron block 8042 to eject the iron block 8042.

[0049] The self-balancing function is achieved through the counterweight 804 installed at the rear of the base 801, so that the infrared sensing component always remains stable at different vehicle body angles, ensuring that the infrared sensor accurately monitors the angle changes between the vehicle body and the ground. Among them, the counterweight 804 structure adopts a magnetic shell 8041. Multiple magnetic shells 8041 can be screwed together and installed. They are located on the side of the base 801 away from the first infrared sensor 802. Through reasonable weight distribution, a balancing torque is formed, so that the base 801 can still automatically reset when the vehicle is driving on different slopes or uneven roads, ensuring the accuracy of the measurement data. The magnetic shell 8041 is equipped with a plug-in cavity and absorbs several iron blocks through magnetic force. 8042. Users can adjust the number of iron blocks 8042 as needed to change the overall counterweight 804, thereby precisely controlling the self-balancing effect of the base 801. For example, in different vehicle models or when the lamp is installed at different angles, appropriately adding or removing iron blocks 8042 can optimize the counterweight 804 effect, making the system suitable for a variety of complex road conditions. In addition, a through hole 8043 is provided on the magnetic housing 8041. Users can insert an iron rod through the through hole 8043 to eject and remove the iron block 8042. The adjustment operation is simple and flexible, without the need for additional tools or disassembly of the entire lamp body, thereby ensuring that the system can be precisely adjusted to the different usage requirements of different vehicles and improving adaptability.

[0050] Through the self-balancing structure of the counterweight 804, when the vehicle is traveling on an arch bridge or a U-shaped sunken section, the base 801 can rely on its own gravity to return to its original position, so that the infrared sensor is always facing the ground, ensuring monitoring accuracy, and accurately feeding back the angle information between the vehicle body and the ground to the control system, thereby realizing automatic adjustment of the angle of the intelligent low beam group 4, so that the headlights can always provide the best lighting effect in different road environments. This self-balancing design based on gravity and magnetic adjustment not only improves the adaptability of the headlight system, but also improves the convenience of maintenance and adjustment, enabling it to flexibly respond to different environmental requirements and ensure the driving safety and lighting stability of new energy electric vehicles at night and in complex road conditions.

The support frame 6 includes a base plate 601, which is fixedly mounted on the rear of the light frame 1 via a first screw 602. A bracket 603 is fixedly mounted on the upper portion of the base plate 601 via a second screw 604. The rotating assembly 7 includes a support base 701, which is fixed to the bracket 603 via a third screw 702 and has a rotating shaft 704 rotatably mounted on one side of the support base 701. A base 801 is fixed to one end of the rotating shaft 704. A brush 605 is fixedly mounted on the upper portion of the bracket 603. The brush 605 is slidably connected to the base 801 and is electrically connected to the first infrared sensor 802 and the second infrared sensor 803. A terminal block 607 fixedly mounted on one side of the bracket 603 is electrically connected to the brush 605 via a wire 608.

[0052] The self-balancing infrared sensing component 8 achieves precise self-balancing and dynamic adjustment functions through the coordinated work of the support frame 6 and the rotating component 7. The support frame 6 is fixed to the rear of the lamp frame 1 to ensure that the entire component remains stable during vehicle driving. The base plate 601 is fixed to the lamp frame 1 by screws, and the bracket 603 is connected to the base plate 601 by a second screw 604 to form a solid support structure. The rotating component 7 achieves flexible rotation through the design of the support seat 701 and the rotating shaft 704. The base 801 is fixed to one end of the rotating shaft 704, so that the self-balancing component can automatically adjust according to the inclination angle of the vehicle body during driving, ensuring that the infrared sensor always maintains an accurate monitoring direction.

[0053] The brush 605 installed on the rotating component 7 is slidably connected to the base 801 to achieve electrical connection and signal transmission. The electrical connection between the brush 605 and the first and second infrared sensors 803 ensures that the sensor data can be accurately transmitted to the control system during the self-balancing process. At the same time, the terminal block 607 transmits the signal to the control system through the wire 608, thereby adjusting the illumination angle of the intelligent low beam group 4 according to the real-time monitoring data to optimize the lighting effect of the car lights.

[0054] Among them, several rotating rods 606 are rotatably installed on the upper part of the bracket 603, and the rotating rods 606 are in rolling contact with the outer wall of the rotating shaft 704. An annular oil chamber 609 is opened inside the bracket 603, and the oil chamber 609 passes through the walls of the several rotating rods 606 in turn for lubrication. A screw cover 9 is screwed on the upper part of the oil chamber 609 of the bracket 603.

[0055] Several rotating rods 606 are mounted on the top of bracket 603. These rods 606 engage the outer wall of shaft 704 in rolling contact, ensuring smooth rotation of shaft 704 for angle adjustment during self-balancing. Furthermore, an annular oil chamber 609 is defined within bracket 603. This chamber is lubricated by the walls of the several rotating rods 606, reducing friction and ensuring smooth operation of rotating components. The lubricating oil within chamber 609 effectively reduces mechanical wear, extending the system's service life and maintaining optimal operating conditions. A screw cap 9 is mounted above chamber 609, sealing it to prevent leakage or contamination, ensuring the stability and long-term effectiveness of the lubrication system.

[0056] Among them, an adjusting member 703 is installed inside the support seat 701, and the end of the adjusting member 703 is movably fitted with the rotating shaft 704. The adjusting member 703 includes a screw rod 7032. One end of the screw rod 7032 rotatably installed inside the support seat 701 extends through the support seat 701 to the outside and is fixedly connected to a knob 7031. A slider 7033 slidably installed inside the support seat 701 is screwed to the screw rod 7032. One side of the slider 7033 is fixedly connected to a contact disk 7034. When adjusting the friction coefficient of the rotating shaft 704, the knob 7031 is rotated to control the friction force between the contact disk 7034 and the rotating shaft 704 to perform friction coefficient adjustment action.

[0057] An adjustment member 703 is installed inside the support base 701. The adjustment member 703 is movably fitted with the end of the rotating shaft 704. By rotating the screw rod 7032 on the adjustment member 703, the adjustment member 703 can adjust the friction coefficient of the rotating shaft 704 to accurately control the rotational resistance and sensitivity of the self-balancing component. When the screw rod 7032 rotates, the slider 7033 is screwed to the screw rod 7032. The other side of the slider 7033 is fixedly connected to the contact plate 7034. The friction between the contact plate 7034 and the rotating shaft 704 is adjusted by the adjustment knob 7031, thereby changing the rotational resistance of the rotating shaft 704, so that the system can adjust the sensitivity and stability of the self-balancing response according to actual needs. When the knob 7031 is rotated, the friction between the contact plate 7034 and the rotating shaft 704 changes accordingly, thereby controlling the rotation characteristics of the rotating shaft 704, ensuring that the infrared sensor always maintains an accurate angle and position, providing stable monitoring data, and ensuring that the self-balancing component can be smoothly adjusted under different vehicle body postures to avoid problems such as over-adjustment or slow response. This adjustment mechanism improves the accuracy and adaptability of the system, and can meet the fine-tuning requirements of different road conditions and vehicles.

[0058] When working, the self-balancing infrared sensing component 8 and the intelligent low-beam light group 4 work together to dynamically adjust the illumination angle to adapt to the changes in the vehicle body posture under different road environments, ensure the best lighting effect and reduce safety hazards. Among them, the self-balancing infrared sensing component 8 is always perpendicular to the direction of gravity under the influence of gravity. No matter whether the vehicle is traveling on an arch bridge, a U-shaped sunken road section or other sloped road section, it can accurately sense the angle change between the vehicle body and the ground. When the vehicle enters the arch bridge, the illumination direction of the ordinary headlights will rise with the angle of the vehicle body, causing the light to be high and may directly hit the field of view of the driver of the oncoming vehicle. At this time, the infrared sensor of the system detects that the illumination distance is shortened and immediately sends a signal to the control The system feedback data, the control system immediately adjusts the angle of the intelligent low beam group 4, so that the light beam is offset downward, ensuring that the light is accurately projected on the road surface, thereby reducing glare interference to oncoming drivers and improving driving safety. When the vehicle enters a U-shaped sunken section, the light beam of the conventional headlights will be overly concentrated on the nearby road due to the downward direction of the vehicle head, resulting in limited distant vision. At this time, the infrared sensor of the system detects that the illumination distance is lengthened and feeds back to the control system. The control system then controls the intelligent low beam group 4 to adjust the angle upward to expand the distant lighting range, ensuring that the driver can promptly detect obstacles or pedestrians ahead, and improving driving safety at night and in complex road environments.
