Description

Technical Field

[0001] The present invention relates to the technical field of automobiles, and in particular to an energy-saving automobile lamp with a mounting angle adjustment structure. Background Art

[0002] Car headlights are devices installed on the outside or inside of a car body to illuminate the road, transmit signals, assist driving safety and improve driving recognition. They are one of the core components of the car safety system. They not only ensure the driver's vision clarity in different environments, but also realize the interaction between the vehicle and the outside world (such as other vehicles, pedestrians, and traffic facilities) through light signals. They are an indispensable functional component of modern cars. Defect 1: At present, there are many car lights on the market, but general car lights are usually fixed directly inside the car body during use, so that the spacing of the headlights is the same when driving at night, which makes it easy for blind spots to appear in the position where the headlights are illuminated, which can easily affect the driver's normal driving and greatly reduce the practicality of the device. Practicality; In order to solve the first defect, the prior art (application number: 202320597423.0, Chinese patent with authorization announcement date of 2023-08-01) discloses an adjustable automobile headlight, which is provided with a slider, a concave hole, a connecting plate, a hydraulic cylinder, and a concave plate. The other side of the support plate is fixed to one side of the concave plate, and the hydraulic cylinder is controlled to drive the connecting plate to slide on the inner wall of the concave plate, so that the inner wall of the connecting hole opened on one side of the slider slides between the cross bar fixed on the inner wall of the concave hole, so as to enable the lamp to remain stable during the adjustment process of the support plate, thereby facilitating the driver to adjust the position of the headlights during driving at night, so as to better observe the spacing between the headlights, so as to better illuminate things on the road and improve the use effect of the device; by setting The limiting block, limiting groove, circular groove and screw are used to bond one side of the glass cover plate to the one side of the support plate, so that the limiting block fixed on one side of the glass cover plate is snap-connected with the inner wall of the limiting groove opened on one side of the support plate, thereby making the connection between the glass cover plate and the support plate more stable, and facilitating better protection of the outside of the lamp. The outer wall of the pad slides with the inner wall of the glass cover plate, which is conducive to controlling the contact between the outer wall of the lamp and the pad when adjusting the position of the lamp on one side of the support plate, avoiding wear on the surface of the lamp caused by the contact between the lamp and the glass cover plate, and improving the practicality of the device; Defect 2: However, dust and other particles carried by the airflow are easy to adhere to the heat dissipation fins at the rear of the car light. By using filter cotton, the incoming airflow will be reduced, and the cooling effect will not be achieved. When using a filter layer, the heat dissipation fins are easily affected by attachments, resulting in reduced heat dissipation effect, and are still prone to damage caused by overheating of the headlights. In order to solve the second defect, the prior art (application number: 202420354434.0, Chinese patent with authorization announcement date of 2025-03-25) discloses a car headlight with good heat dissipation effect. When the vehicle is driving, the second air duct takes in air. When the second air duct takes in air, the fan blades rotate to drive the first rotating shaft to rotate. The rotation of the first rotating shaft drives the second rotating shaft to rotate through the belt, thereby driving the gear to rotate. The rotation of the gear drives the annular hollow bracket with a gear ring to rotate, so that the brush strips in the annular hollow bracket clean the heat dissipation fins, avoiding the problem of poor heat dissipation effect caused by dust adhesion and accumulation.

[0003] In the prior art, a hydraulic cylinder is used to drive the lamp to move left and right, so that the lamp can better illuminate the things on the road. However, the adjustment range of the installation angle of the car headlamp is limited, resulting in the light beam of the car headlamp being concentrated on the bottom surface when the car is going uphill or downhill, causing insufficient illumination of the far road surface, there is a lighting blind area, and a large amount of heat will be generated when the car headlamp is used for a long time, which greatly shortens the service life of the light source and accelerates the damage of the optical components, affecting the lighting effect. Therefore, we propose an energy-saving car headlamp with an installation angle adjustment structure to solve the problems mentioned above. Summary of the Invention

[0007] Preferably, the top of the rotating shaft penetrates through the inside of the support plate, and the rotating shaft and the second worm are in meshing connection.

[0008] Preferably, the telescopic end of the heat-conducting telescopic rod contacts the inner wall of the lamp cover, and a return spring is installed inside the heat-conducting telescopic rod.

[0009] Preferably, air outlet holes and air inlet holes are respectively opened at the top and bottom of the lamp cover. The positions of the air outlet channel and the air outlet holes correspond to each other. The positions of the air inlet sub-channel and the air inlet holes correspond to each other, and the air inlet sub-channel is connected to the inside of the dust-proof net.

[0010] Preferably, an adjustment plate is provided inside the air intake secondary channel, a rack and a driven gear are respectively connected to the left side of the air intake secondary channel inside the vehicle body, and a connecting spring is fixed to the top of the rack.

[0011] Preferably, the driven gear is rotatably arranged inside the vehicle body, and the shaft end of the driven gear extends into the interior of the intake secondary channel, and the adjustment plate is sleeved and fixed on the shaft end of the driven gear.

[0012] Preferably, the rack and the driven gear are meshed, one end of the connecting spring away from the rack extends into the interior of the lampshade, and one end of the connecting spring contacts the outer side of the heat-conducting telescopic rod, and the connecting spring is made of nickel-titanium alloy.

[0013] Preferably, heat dissipation holes are provided at equal intervals on the right side of the mounting plate, dust screens are bolted to the inside of the main air intake channel and the air outlet channel, and the right side of the inside of the main air intake channel is connected to the turbine through an axial rotation, the right side bearing inside the vehicle body is connected to a reciprocating screw, and a fixed rod is symmetrically fixedly connected to the center point of the reciprocating screw inside the vehicle body, cleaning brushes are installed on the outer sides of the two fixed rods and the reciprocating screw, and the bottom of the reciprocating screw is connected to the shaft end of the turbine through a bevel gear set.

[0014] Preferably, the bottom of the reciprocating screw extends into the interior of the main air inlet channel, the cleaning brush is threadedly connected to the reciprocating screw, and the cleaning brush is slidingly connected to the two fixed rods, and the bristles of the cleaning brush are in contact with the surface of the heat dissipation hole.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: in the energy-saving automobile lamp with an installation angle adjustment structure, the staff rotates the first worm and the second worm respectively to drive the first worm gear and the second worm gear, so that the rotating plate and the rotating shaft can adjust the vertical and horizontal angles of the lamp assembly. After adjustment, the angle is stable and vibration-resistant. At the same time, the heat-conducting telescopic rod on the outside of the lamp assembly cooperates with the flow of external air through the inlet and outlet channels when the car is driving to discharge heat for efficient heat dissipation and avoid light decay. The specific contents are as follows:

[0016] (1) When the installation angle of the headlight assembly needs to be adjusted, the staff rotates the first worm and drives the first worm wheel to rotate, and uses the rotating plate to drive the headlight assembly to rotate up and down. At the same time, the staff rotates the second worm and drives the second worm wheel to rotate, and uses the rotating shaft to drive the movable frame and the headlight assembly to rotate left and right, thereby achieving the angle adjustment of the headlight assembly. At the same time, the angle is stable after adjustment and is not easily displaced due to vibration.

[0017] (2) By utilizing the multiple heat-conducting telescopic rods provided on the outside of the headlight assembly, the heat generated by the headlight assembly during operation can be transferred to the outside air. At the same time, when the car is driving, the outside air will enter the lampshade through the main air intake channel and the auxiliary air intake channel and blow toward the headlight assembly, which can discharge the heat from the air outlet channel, thereby efficiently dissipating the heat of the headlight assembly and avoiding local overheating and light decay. Furthermore, since a reset spring is provided inside the heat-conducting telescopic rod, when the headlight assembly rotates up and down, the heat-conducting telescopic rod is always in contact with the inner wall of the lampshade and transfers the heat to the lampshade, which can heat the lampshade, thereby preventing the formation of condensed water mist on the inside or outside of the lampshade and avoiding blurred lighting caused by waterline heat dissipation.

[0018] (3) By setting up multiple heat dissipation holes, the heat inside the lampshade can be quickly discharged from the heat dissipation holes, thereby reducing the temperature of the lamp assembly and avoiding overheating damage. At the same time, the airflow during driving is used to drive the turbine to rotate, and the reciprocating screw is driven to rotate through the bevel gear set, so that the cleaning brush moves back and forth along the surface of the heat dissipation hole and cleans the heat dissipation hole to prevent the heat dissipation hole from being blocked by impurities and dust and affecting the heat dissipation.

[0019] (4) Since the connecting spring is made of memory metal material, after absorbing heat, the connecting spring stretches and pushes the rack downward. At the same time, the rack drives the driven gear to rotate, so that the adjustment plate rotates to a vertical state. At this time, the air intake channel is fully opened. When the headlight assembly is not working, the connecting spring returns to a compressed state and drives the rack to reset upward. At this time, the adjustment plate rotates to a tilted state, and the air intake channel is half closed, thereby increasing the air intake volume at high temperatures and improving the heat dissipation efficiency.

DETAILED DESCRIPTION

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0032] See also Figures 1-10 , the present invention provides the following technical solutions: an energy-saving automobile lamp with a mounting angle adjustment structure;

[0033] Example 1: In order to solve the problem in the prior art that the automobile headlights have a limited range of adjustment for the installation angle, resulting in a blind spot when going up and downhill, and the heat generated by long-term use will shorten the life of the light source, accelerate the damage of the optical components, and affect the lighting effect, the following solution is disclosed. Figures 1-4 and Figure 8As shown in the figure, it includes a vehicle body 1. On the left side of the vehicle body 1, a mounting plate 2 and a lamp housing 4 are embedded and installed, and a vehicle lamp assembly 3 is arranged inside the lamp housing 4. It further includes: symmetrically and fixedly connected to the left side of the mounting plate 2 are support plates 5. Between the two support plates 5, a movable frame 6 is rotatably connected through a rotating shaft 12. The vehicle lamp assembly 3 is hinged to the inner wall of the movable frame 6 through a rotating plate 9. A first worm gear 8 is sleeved and fixed at the shaft end of the rotating plate 9. A first worm 7 penetrates through the inside of the movable frame 6. A second worm gear 11 is sleeved and fixed on the outer side of the top of the rotating shaft 12. A second worm 10 penetrates through the inside of the mounting plate 2. The lamp housing 4 is installed on the inner wall of the vehicle body 1 through multiple bolts. The movable frame 6 is arranged in a "C" shape. The first worm 7 and the first worm gear 8 are in meshing connection, and the first worm 7 and the movable frame 6 are in rotating connection. The top of the rotating shaft 12 penetrates through the inside of the support plate 5, and the rotating shaft 12 and the second worm 10 are in meshing connection. Heat-conducting telescopic rods 14 are fixedly arranged at equal angles on the outer side of the vehicle lamp assembly 3. The telescopic ends of the heat-conducting telescopic rods 14 are in contact with the inner wall of the lamp housing 4, and a return spring is installed inside the heat-conducting telescopic rods 14. An air outlet channel 18 and an air intake main channel 15 are respectively opened and installed above and below the inside of the vehicle body 1. The top of the air intake main channel 15 is provided with an air intake sub-channel 19. Air outlet openings and air inlet openings are respectively opened at the top and bottom of the lamp housing 4. The positions of the air outlet channel 18 and the air outlet opening correspond to each other. The positions of the air intake sub-channel 19 and the air inlet opening correspond to each other. The air intake sub-channel 19 is connected to the inside of the dust-proof net 16.

[0034] When it is necessary to adjust the installation angle of the vehicle lamp assembly 3, the staff rotates the first worm 7 to drive the first worm gear 8 to rotate, and uses the rotating plate 9 to drive the vehicle lamp assembly 3 to rotate up and down. At the same time, the staff rotates the second worm 10 to drive the second worm gear 11 to rotate, and uses the rotating shaft 12 to drive the movable frame 6 and the vehicle lamp assembly 3 to rotate left and right, so as to realize the angle adjustment of the vehicle lamp assembly 3. At the same time, the adjusted angle is stable and is not easily displaced due to vibration. Then, when the vehicle lamp assembly 3 works for a long time, a large amount of heat will be generated. At this time, with the help of multiple heat-conducting telescopic rods 14, the heat generated when the vehicle lamp assembly 3 works can be transferred to the external air. At the same time, when the vehicle is running, the external air will enter the lamp housing 4 through the air intake main channel 15 and the air intake sub-channel 19 and blow towards the vehicle lamp assembly 3, and the heat can be discharged from the air outlet channel 18, so as to efficiently dissipate the heat of the vehicle lamp assembly 3 and avoid light decay caused by local overheating. And because a return spring is arranged inside the heat-conducting telescopic rod 14, when the vehicle lamp assembly 3 rotates up and down, the heat-conducting telescopic rod 14 is always in contact with the inner wall of the lamp housing 4 and transfers the heat to the lamp housing 4, which can heat the lamp housing 4, thereby preventing the formation of condensation water mist on the inner or outer side of the lamp housing 4 and avoiding the problem of lighting blur caused by water line heat dissipation.

[0035] Example 2: Different from Example 1, this example utilizes the heat generated by the lamp assembly 3 to automatically adjust the air intake and improve the heat dissipation efficiency. Figure 1 、 Figure 6 、 Figure 9 and Figure 10 As shown, an adjustment plate 22 is provided inside the air intake secondary channel 19, and a rack 24 and a driven gear 23 are respectively connected to the left side of the air intake secondary channel 19 inside the vehicle body 1, and a connecting spring 25 is fixed to the top of the rack 24. The driven gear 23 is set inside the vehicle body 1 through an axis rotation, and the shaft end of the driven gear 23 extends into the interior of the air intake secondary channel 19. The adjustment plate 22 is sleeved and fixed on the shaft end of the driven gear 23. The rack 24 and the driven gear 23 are meshedly connected. One end of the connecting spring 25 away from the rack 24 extends into the interior of the lampshade 4, and one end of the connecting spring 25 contacts the outer side of the heat-conducting telescopic rod 14. The connecting spring 25 is made of nickel-titanium alloy.

[0036] Since the connecting spring 25 is made of memory metal material, after absorbing heat, the connecting spring 25 stretches and pushes the rack 24 to move downward. At the same time, the rack 24 drives the driven gear 23 to rotate, so that the adjustment plate 22 rotates to a vertical state. At this time, the air intake sub-channel 19 is fully opened. When the headlight assembly 3 is not working, the connecting spring 25 returns to a compressed state and drives the rack 24 to reset upward. At this time, the adjustment plate 22 rotates to an inclined state, and the air intake sub-channel 19 is half closed, thereby increasing the air intake volume at high temperatures and improving the heat dissipation efficiency.

[0037] Example 3: Different from Example 2, this example uses the airflow when the car is running to drive the turbine 17 to rotate and drive the cleaning brush 21 to move up and down to clean the heat dissipation hole 13. Figure 1 and Figure 5-Figure 7 As shown, heat dissipation holes 13 are opened at equal intervals on the right side of the mounting plate 2, and dust screens 16 are bolted to the inside of the main air intake channel 15 and the air outlet channel 18, and the right side of the inside of the main air intake channel 15 is connected to the turbine 17 through an axis rotation, and the right side bearing inside the vehicle body 1 is connected to the reciprocating screw 20, and the inside of the vehicle body 1 is symmetrically fixed with a fixing rod 26 about the center point of the reciprocating screw 20, and a cleaning brush 21 is installed on the outer side of the two fixing rods 26 and the reciprocating screw 20, and the bottom of the reciprocating screw 20 is connected to the shaft end of the turbine 17 through a bevel gear set. The bottom of the reciprocating screw 20 extends into the inside of the main air intake channel 15, and the cleaning brush 21 is threadedly connected to the reciprocating screw 20, and the cleaning brush 21 is slidably connected to the two fixed rods 26, and the brush position of the cleaning brush 21 is in contact with the surface of the heat dissipation hole 13.

[0038] By setting up multiple heat dissipation holes 13, the heat inside the lampshade 4 can be quickly discharged from the heat dissipation holes 13, thereby reducing the temperature of the headlight assembly 3 and avoiding overheating damage. At the same time, the airflow during driving is used to drive the turbine 17 to rotate, and the reciprocating screw 20 is driven to rotate through the bevel gear set, so that the cleaning brush 21 moves back and forth along the surface of the heat dissipation holes 13 and cleans the heat dissipation holes 13 to prevent the heat dissipation holes 13 from being blocked by impurities and dust and affecting the heat dissipation.

[0039] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein.
