DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] like Figure 2 As shown, a dimming vehicle lamp comprises a bracket 1, a lamp holder 2, a first lamp body 3, an adjusting screw 4 and an adjusting nut 5. A rotating shaft 31 is provided at the front end of the first lamp body 3, and the first lamp body 3 is rotatably connected to the inner side of the bracket 1 through the rotating shaft 31. A hinge rod 32 is provided at the rear end of the first lamp body 3. A hinge hole 201 is provided in the middle of the lamp holder 2. The first lamp body 3 is hinged in the hinge hole 201 through the hinge rod 32. The adjusting nut 5 is connected to the rear part of the lamp holder 2. A boss 11 is provided at one end of the bracket 1 away from the rotating shaft 31. An umbrella tooth 41 extending out of the boss 11 is provided at one end of the adjusting screw 4, and a thread is provided at the other end. The threaded end of the adjusting screw 4 is inserted into the boss 11 and threadedly connected to the adjusting nut 5. The middle part of the adjusting screw 4 is rotatably connected in the boss 11.

[0029] The working principle or implementation method is as follows: the bracket 1 supports the lamp holder 2 and the first lamp body 3, and can also be used to connect with other parts of the vehicle body, such as a lampshade, etc. The adjusting screw 4 and the adjusting nut 5 are both arranged in the dimming lamp, and an adjusting gear rod 15 such as a screwdriver is inserted at the position of the bevel gear 41 to drive the bevel gear 41 to rotate. The rotation of the bevel gear 41 drives the adjusting screw 4 to rotate, thereby engaging with the adjusting nut 5, driving the lamp holder 2 to rise, so that the first lamp body 3 rotates around the rotation axis 31. At the same time, due to the limitation at the hinge hole 201, it stops after rotating a certain angle, thereby achieving the longitudinal adjustment of the direct lighting angle of the lamp. This makes it convenient during assembly, and the overall position of the lamp does not need to be adjusted too much. After the lamp is assembled as a whole, the angle of the lamp can be adjusted to a suitable value by an external screwdriver, etc., which can improve the assembly efficiency and facilitate the automated assembly of the lamp.

[0030] A sealing gasket 6 is provided between the upper end of the boss 11 and the bevel gear 41. The sealing gasket 6 can not only make up the installation gap between the boss 11 and the bevel gear 41, so that the height of the boss 11 does not need to be too high, but also can reduce shock and resist wear, and prevent the adjustment screw 4 from colliding with the boss 11 during the rotation of the rotating shaft 31, thereby preventing interference with the rotational motion.

[0031] It is recommended that the sealing gasket 6 be made of a rubber material with good elasticity and wear resistance, such as NBR nitrile rubber or EPDM ethylene propylene diene monomer rubber, to ensure that it can maintain good sealing and shock absorption performance for a long time under high temperature and high pressure environment. The specific size should be determined according to the actual working conditions. Normally, the diameter of the sealing gasket 6 is slightly larger than the top diameter of the boss 11 by about 0.5-1mm, and the thickness is about 1-2mm. In addition to the standard round sealing gasket, it is also possible to consider using V-shaped or other special-shaped cross-section seals, which can further enhance the shock absorption performance while also improving the pressure resistance and the ability to adapt to complex working conditions.

[0032] The middle part of the adjusting screw 4 is rotated and limited in the boss 11 by the clamp 8. In this way, the adjusting screw 4 can be prevented from moving up and down inside the boss 11. The use of the clamp 8 can facilitate the installation of the adjusting screw 4. After using the clamp 8, there is no need to set the limit of the screw in the inner hole of the boss 11, which is convenient for the setting of the boss 11. First, the adjusting screw 4 is inserted into the central through hole of the boss 11, and then the position of the screw is adjusted, and finally the clamp 8 is used to fix it tightly. At this time, due to the effect of the clamp 8, even if an external force is applied, the adjusting screw 4 cannot be displaced along the axial direction, thereby achieving the effect of limiting. At the same time, since the clamp 8 allows a certain degree of rotation, it will not hinder the adjusting screw 4 from rotating around its own axis, meeting the needs of actual use. In addition to using the clamp 8 as a fixing member, other limiting rings such as a retaining ring and a sealing ring can also be considered to replace the clamp 8 for limiting.

[0033] like Figure 3 As shown, a receiving cavity 12 for supporting the second lamp body is provided inside the bracket 1, and the second lamp body is fixedly connected in the receiving cavity 12. In this way, the same bracket 1 can simultaneously install the first lamp body 3 and the second lamp body, such as the fog lamp and the headlight of the vehicle. The core of this design is to use a highly integrated bracket structure to achieve the goal of supporting multiple lighting functions in a small area. The bracket 1 is made of high-strength aluminum alloy material with good corrosion resistance and mechanical strength; the shape and size of the receiving cavity 12 are customized according to the specific model of the first lamp body 3 to ensure a close fit. The first lamp body 3 can select different types of light sources, such as LED or xenon lamp. When working, the current is distributed to different first lamp bodies 3 through the circuit control system, so that they are lit in turn. Since a special receiving cavity 12 is provided inside the bracket 1, even if multiple first lamp bodies 3 are installed on the same bracket, there will be no interference, which ensures the stability of their respective operations. When installing, the bracket 1 needs to be fixed at a predetermined position, and a suitable first lamp body 3 is selected according to actual needs, and it is inserted into the corresponding receiving cavity 12 to ensure that the connection between the first lamp body 3 and the bracket 1 is stable and reliable, and the power cord is connected for testing. In addition, it is also possible to consider adding an intelligent temperature control system based on the bracket 1 to automatically adjust the working state of each first lamp body 3 through ambient temperature monitoring, so as to further improve the lighting effect while protecting the lamp from high temperature damage.

[0034] When the vehicle starts, the current is distributed to different first lamp bodies 3 through the circuit control system, so that they light up in sequence. Since the bracket 1 is provided with a special accommodating cavity 12, even if multiple first lamp bodies 3 are installed on the same bracket, there will be no interference, thus ensuring the stability of their respective operations.

[0035] A rotating shaft is connected to the outer side of the bracket 1. The rotating shaft is used to adjust the installation angle of the bracket 1, thereby adjusting the installation angle of the first lamp body 3 on the bracket 1, and adjusting the illumination angle of the first lamp body 3 in coordination.

[0036] See also Figure 1As shown, the bracket 1 is connected to the lampshade 9, and the lampshade 9 is used to install the dimming lamp as a whole on the car body. The lampshade 9 is provided with anti-collision support plates 7 at the upper, middle and lower positions corresponding to the bracket 1. In this way, the bracket 1 and the first lamp body 3 installed on the bracket 1 can be well protected, and the cost of repairing the first lamp body 3 can be saved if there is no damage. The bracket 1 is made of high-strength alloy material to ensure sufficient support strength; the material of the lampshade 9 is preferably plastic or glass fiber composite material with high transparency and good toughness, which is both light-transmissive and light-weight; the anti-collision support plate 7 is made of elastic material with excellent energy absorption effect, such as polyurethane foam, with a thickness of about 5-10mm, which can absorb most of the impact energy without permanent deformation. When the car encounters a collision, the first thing it contacts is the outermost anti-collision support plate 7, which will quickly absorb and disperse the energy of the shock wave to prevent it from being directly transmitted to the first lamp body 3 and other internal components. Subsequently, the middle layer of the anti-collision support plate 7 further consumes the remaining energy until the last line of defense, that is, the lower anti-collision support plate 7, plays the final protective role. This progressive protection strategy from outside to inside ensures the functional integrity of the dimming headlights to the greatest extent even under high-speed collision conditions. The anti-collision support plate 7 can be replaced with products of different materials or shapes according to actual needs to adapt to more types of impact test standards. Taking into account the high requirements for appearance design of some high-end models, the design of the anti-collision support plate 7 can be optimized without reducing the anti-collision performance, so that it fits the curve of the lampshade 9 more closely, and it can even be integrated with the lampshade by spraying or embedding to achieve a concealed installation effect. At the same time, it is also possible to explore the use of smart material characteristics to develop new anti-collision materials with self-repairing functions to further improve the safety protection level of lamps.

[0037] The anti-collision support plate 7 has multiple bends for elastic anti-collision. The bends can well buffer the impact force and improve the protection performance of the first lamp body 3.

[0038] The lampshade 9 includes a glass cover 91 and a mounting seat 92. The glass cover 91 is clamped with the mounting seat 92. The mounting seat 92 is provided with a through hole 921 near the bevel gear 41. The through hole 921 is used to insert the adjustment gear rod 15 that drives the bevel gear 41 to rotate. A screwdriver, for example, is inserted into the adjustment gear rod 15 through the through hole 921. The glass cover 91 is used to transmit light, and the mounting seat 92 is used to install the entire lamp to the vehicle body.

[0039] The upper part of the bracket 1 is connected with a ball head seat 13, on which the ball head end of the motor ball head 14 is hinged, and the hinge has damping, and the body of the motor ball head 14 is connected to the mounting seat 92. The motor rotation of the motor ball head 14 drives the ball head end to rotate, thereby driving the ball head seat 13 to deflect, so that the bracket 1 and the mounting seat 92 can rotate relative to each other, so as to electrically adjust the angle of the lamp holder 2 installed on the bracket 1, thereby adjusting the direction of the light of the first lamp body 3.

[0040] The motor ball head 14 is the core driving force source responsible for realizing the angle adjustment function. When the user inputs the desired target position through the external interface, the built-in microprocessor will calculate the corresponding control strategy and issue action instructions to the motor. Throughout the process, the coordination between various components is crucial to ensure that the system can complete efficient operation with low energy consumption.

[0041] In addition to the above-mentioned design based on a single motor ball head 14, a dual-motor collaborative mode can also be considered, that is, controlling two independent ball head seats 13 respectively for more precise multi-dimensional adjustment, further improving the flexibility of lamp angle adjustment. Or a manual ball head connected to the ball head seat can be added for manual adjustment.

[0042] The motor ball head 14 can be replaced with a small DC reduction motor of different specifications and models according to the actual load conditions; the damping element can also be replaced by other soft materials such as rubber according to the actual situation.

[0043] The rotation angle of the first lamp body 3 around the rotation axis 31 is less than 10°, which is suitable for the vehicle illumination angle adjustment range and can adjust the illumination angle of the first lamp body 3 to an appropriate value as quickly as possible.

[0044] The sealing gasket 6 can be made of high temperature resistant and anti-aging materials to ensure that it is not easily deformed during long-term use; the clamp 8 is made of metal material with high strength and long service life; the design of the anti-collision support plate 7 has been optimized through mechanical simulation and can maintain good recovery ability while withstanding a certain impact force; the working voltage of the motor ball head 14 is 12V DC voltage, and the maximum output torque can reach 5Nm, which can meet the needs of different models.

[0045] In some embodiments, when the angle of the entire bracket 1 needs to be adjusted, an instruction can be sent to the motor ball head 14 through an external controller to rotate it according to a preset program. The rotation of the motor ball head 14 drives the bracket 1 on the ball head seat 13 to deviate along the rotating axis, thereby changing the lamp projection angle. At this time, the bevel gear 41 rotates with the first lamp body 3. If it is necessary to adjust the projection angle of the lower first lamp body 3 such as the fog lamp, it can be achieved by inserting a screwdriver into the through hole 921 and driving the bevel gear 41 to rotate, which will not cause relative sliding between the first lamp body 3 and the bracket 1. In addition, the sealing gasket 6 not only plays a sealing role, but also absorbs a certain amount of vibration energy to reduce the shaking amplitude of the first lamp body 3 during driving.

[0046] Operation steps and precautions: S1: After assembling the entire dimming headlight, install it to the predetermined position of the vehicle through the mounting seat 92; S2: Turn on the power and turn on the dimming function in the onboard computer; S3: Select the appropriate dimming mode according to actual needs, such as automatically tracking the changes in the road conditions ahead or manually setting a fixed angle; S4: Confirm that the first lamp body 3 has been correctly aligned with the target area and can be used normally. When fine-tuning the illumination angle of the first lamp body 3, the adjustment gear rod 15 such as a screwdriver can be used to adjust the adjustment screw 4, driving the first lamp body 3 to deflect relative to the bracket 1, so as to more quickly adjust the position of the lower first lamp body 3, such as avoiding the overlapping area of ​​the two illuminations. In this way, there is no need to effectively control the installation position of the first lamp body 3 during assembly, thereby indirectly speeding up the assembly efficiency of the entire dimming headlight. Note: Regularly check whether each connection part is tightened, especially the state of the clamp 8 and the sealing gasket 6, to prevent loosening and causing safety hazards; regularly clean the attachments on the surface of the anti-collision support plate 7 to avoid reducing the energy absorption efficiency.
