Description

Technical Field

[0001] The present invention relates to the field of vehicle lamps, and specifically to an adaptive intelligent combined vehicle lamp. Background Art

[0002] The front vehicle lamp is an important part of a vehicle, and is used for lighting at night or in bad weather with insufficient light such as rain, snow, fog, etc. With the development of the automotive industry, current vehicle lamps have made remarkable progress in terms of brightness, irradiation distance, etc.

[0003] In addition to the basic lighting function, current adaptive vehicle lamps can also automatically adjust the brightness, irradiation angle, and high and low beams of the light according to the driver's needs or the driving conditions of the vehicle. For example, an adaptive intelligent combined vehicle lamp with the publication number of CN110626256A in the prior art.

[0004] Since adaptive vehicle lamps do not require manual control, the high and low beam switching of the vehicle lamps is very frequent in some complex road conditions. In recent years, most newly produced vehicle models adopt an integrated high and low beam headlamp. For this type of vehicle lamp, the high beam and the low beam share the same light source, and the light propagation path is adjusted by flipping a light-shielding plate, so as to achieve the purpose of adjusting the high and low beams. For example, a vehicle lamp with integrated high and low beams with the publication number of CN103363410B.

[0005] The flipping of the light-shielding plate is generally controlled by a motor. The motor and the light-shielding plate are enclosed inside the vehicle lamp together. Frequent high and low beam switching, firstly, easily causes the motor to switch on and off frequently, increasing the heat generation of the motor. Secondly, excessive use of the motor is more likely to cause damage or accelerate aging. Moreover, since the motor and the light-shielding plate are enclosed inside the outer shell of the vehicle lamp, its heat generation is likely to affect the light source, resulting in the vehicle lamp overheating. Once damaged, it is necessary to open the outer shell of the vehicle lamp for repair, which is not only troublesome but also affects the sealing effect of the vehicle lamp. Summary of the Invention

[0023] Compared with the prior art, the present invention provides an adaptive automotive intelligent combined headlight, having the following beneficial effects:

[0024] 1. By arranging a magnetic component outside the inner lamp housing, the magnetic force of the electromagnet is used to pull the traction wire to control the flipping of the light shielding plate, thereby realizing the switching between high and low beams. Since the magnetic component is outside the inner lamp housing, even if it generates heat during operation, it will not affect the inside of the inner lamp housing.

[0025] Moreover, the winding shaft, clockwork spring, etc. inside the inner lamp housing, which are related to the flipping of the light shielding plate, are all mechanical structures without electronic components, not easily damaged, and more reliable. Even if the magnetic component is damaged, there is no need to open the inner lamp housing for maintenance, which is more convenient and will not affect the sealing performance of the inner lamp housing.

[0026] 2. By driving the regulating shaft to rotate through the second motor to adjust the irradiation angle of the glass lamp shade, during this process, the contact position between the electrode piece and the annular resistor can be used to reflect the angle of the lighting component. Based on this, the magnetic force of the electromagnet is controlled through the vehicle-mounted computer, and then the irradiation distance after the high beam is turned on is controlled, so that the farther the lighting component irradiates in the low beam state, the smaller the increase amplitude of the irradiation distance after the high beam is turned on, avoiding the irradiation distance of the vehicle lamp being too far and affecting oncoming vehicles.

[0027] 3. The extension beam and the U-shaped connecting frame are used to form a lever with the regulating shaft as the fulcrum. Similarly, the contact position between the electrode piece and the annular resistor is used to reflect the angle of the lighting component. Based on this, the first motor is controlled to rotate through the vehicle-mounted computer, and then the counterweight slides on the extension beam, thereby adjusting the force arm of the counterweight to make both ends of the lever as balanced as possible. After the lever is balanced, the load borne by the second motor and the regulating shaft will be smaller, reducing the pressure on both of them. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0043] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0044] As Figures 1-13 shown, the present invention provides an adaptive automotive intelligent combined headlamp, including an outer lamp housing 1, a glass lamp shade 2 is provided on the front side of the outer lamp housing 1, two lighting components 3 are provided inside the outer lamp housing 1, a turn signal 4 is provided on the rear side of the glass lamp shade 2, two inner lamp housings 5 are provided inside the outer lamp housing 1, and the two lighting components 3 are respectively located inside the two inner lamp housings 5;

[0045] The lighting component 3 includes a reflecting bowl 13 disposed inside the inner lamp housing 5. A light source 16 is fixedly provided on the inner rear wall of the reflecting bowl 13. A panel 17 is provided in front of the reflecting bowl 13 by bolts. A lens 14 for converging light is provided in front of the panel 17. An installation bracket 15 is fixedly provided at the outer end of the lens 14, and the installation bracket 15 is fixedly provided on the front side of the panel 17;

[0046] During the driving of the vehicle, the two lighting components 3 emit light, playing a role in lighting. The turn signal 4 can only flash when the vehicle turns. The reason for the lighting of the lighting component 3 is that the light source 16 emits light inside the reflecting bowl 13, and the reflective coating on the inner wall of the reflecting bowl 13 refracts the light and shoots it forward. The emitted light passes through the lens 14 and is refracted again. The lens 14 makes the light shoot forward more concentratedly, improving the irradiation effect.

[0047] Under different road conditions, it is necessary to switch between high beam and low beam. As Figures 4-9 shown, a baffle 28 for blocking light is fixedly provided on the panel 17. A light-shielding plate 29 is inlaid on the baffle 28. Two connecting arms 30 are fixedly provided on the front side of the light-shielding plate 29. A winding shaft 31 is provided on the front side of the baffle 28, and the bottom ends of the two connecting arms 30 are fixedly provided at the outer ends of the winding shaft 31;

[0048] When the light irradiates outward through the reflecting bowl 13, part of the light will be blocked by the baffle 28 and the light-shielding plate 29. At this time, the lighting component 3 is in the low beam state. When it is necessary to switch to the high beam, the winding shaft 31 drives the connecting arm 30 to rotate, and then drives the light-shielding plate 29 to flip to a horizontal state. After the light-shielding plate 29 flips, a notch will be generated on the baffle 28, and the blocked light will shoot out from the notch, thus switching to the high beam state;

[0049] Both ends of the winding shaft 31 are provided with end plates 33 through rotating shafts. The end plates 33 are fixedly provided on the front side of the baffle 28. Hairspring springs 34 are provided at both ends of the winding shaft 31, and the elastic force of the hairspring springs 34 can maintain the light-shielding plate 29 in a closed state.

[0050] When the light-shielding plate 29 is closed, the hairspring spring 34 is in a natural relaxed state. When the light-shielding plate 29 starts to flip, the rotation of the winding shaft 31 will cause the hairspring spring 34 to gradually tighten. When the force driving the light-shielding plate 29 to flip disappears, the elastic force of the hairspring spring 34 will drive the winding shaft 31 to rotate back, so that the light-shielding plate 29 re-closes the notch of the baffle 28.

[0051] The force for controlling the flipping of the light-shielding plate 29 is transmitted from the outside of the inner lamp housing 5. As Figures 4-9As shown, a traction wire 18 is wound around the outer end of the winding shaft 31. A fixed pulley 32 for changing the direction of the traction wire 18 is fixedly provided at the bottom end of the panel 17. One end of the traction wire 18 bypasses the outer end of the fixed pulley 32 and extends to the rear side of the panel 17. A bottom plate 35 is fixedly provided at the bottom end of the panel 17;

[0052] A rubber sleeve 19 is fixedly provided at the rear side of the bottom plate 35. The rear end of the rubber sleeve 19 extends to the rear side of the inner lamp housing 5. The rear end of the traction wire 18 extends to the rear side of the inner lamp housing 5 through the rubber sleeve 19. The elasticity of the rubber sleeve 19 enables the outer end of the traction wire 18 to be in close contact with the inner wall of the rubber sleeve 19. A magnetic force assembly 7 for driving the traction wire 18 is provided at the rear side of the inner lamp housing 5. The rear end of the traction wire 18 is connected to the magnetic force assembly 7.

[0053] The magnetic force assembly 7 located at the rear side of the inner lamp housing 5 can pull the traction wire 18. When the traction wire 18 is pulled, the winding shaft 31 will rotate, thereby causing the light-shielding plate 29 to flip. Since the magnetic force assembly 7 is outside the inner lamp housing 5 and the force is transmitted by the traction wire 18, even if the magnetic force assembly 7 generates heat during operation, it will not affect the inside of the inner lamp housing 5. Moreover, the structures related to the flipping of the light-shielding plate 29 such as the winding shaft 31 and the clockwork spring 34 inside the inner lamp housing 5 are all mechanical structures without electronic components, which are not easily damaged and have higher reliability. Even if the magnetic force assembly 7 is damaged, it is not necessary to open the inner lamp housing 5 for maintenance, which is more convenient and will not affect the sealing performance of the inner lamp housing 5.

[0054] During use, the lighting assembly 3 is sealed inside the inner lamp housing 5. As Figure 2 shown, a partition is fixedly provided on the inner wall of the outer lamp housing 1. A sealing ring is fixedly provided at the outer end of the inner lamp housing 5. The front end of the inner lamp housing 5 extends to the front side of the partition. The sealing ring is detachably provided at the rear side of the partition. The front side of the partition is in a sealed state. A sealed inspection cover is provided at the top end of the outer lamp housing 1 through bolts. After opening it, various components at the rear side of the partition can be inspected;

[0055] By passing the front end of the inner lamp housing 5 through the partition and installing the sealing ring at the outer end of the inner lamp housing 5 at the rear side of the partition, the inner lamp housing 5 can be installed inside the outer lamp housing 1. Moreover, the inner lamp housing 5, the partition, the outer lamp housing 1 and the glass lamp shade 2 directly form a sealed space, in which the lighting assembly 3 is enclosed, which can play a role in waterproofing and dustproofing and improving the lighting effect.

[0056] Pulling the traction wire 18 requires the assistance of magnetic force, and the magnitude of the magnetic force directly determines the flipping degree of the light-shielding plate 29. As Figures 4-10 shown in FIGS. 12 and 13, the magnetic force assembly 7 is located at the rear side of the partition. The magnetic force assembly 7 includes a mounting piece 701 provided on the inner wall of the outer lamp housing 1. An electromagnet 702 is fixedly provided on the front side of the mounting piece 701. The input end of the electromagnet 702 is provided with a vehicle computer 6;

[0057] Two slide bars 704 are fixedly provided on the front side of the mounting piece 701. A slide seat 705 is sleeved on the outer end of the slide bar 704. A limiting piece 706 for blocking is fixedly provided at the front end of the slide seat 705.

[0058] An iron block 703 is provided directly in front of the electromagnet 702. The two slide seats 705 are respectively fixedly arranged on both sides of the iron block 703. One end of the traction wire 18 is fixedly arranged on the front side of the iron block 703. By the magnetic force of the electromagnet 702 attracting the iron block 703, the traction wire 18 can be pulled.

[0059] When it is necessary to switch the lighting component 3 from low beam to high beam, the electromagnet 702 is powered on to generate magnetic force. The magnetic force attracts the iron block 703 and makes the slide seat 705 slide along the slide bar 704. The iron block 703 approaches the electromagnet 702 and pulls the traction wire 18. The traction wire 18 thus pulls the winding shaft 31 and makes the light shielding plate 29 flip, so as to achieve the purpose of switching between low beam and high beam. During the process of the electromagnet 702 pulling the traction wire 18, the magnetic force of the electromagnet 702 is used to offset the elastic force of the spring 34 during the rotation of the winding shaft 31. The greater the magnetic force of the electromagnet 702, the greater the flipping angle of the light shielding plate 29, and the greater the increase amplitude of the irradiation distance of the lighting component 3 when it is switched to high beam. That is to say, the magnitude of the magnetic force of the electromagnet 702 is proportional to the irradiation distance of the lighting component 3 in the high beam state.

[0060] In addition to switching between low beam and high beam, the irradiation angle of the lighting component 3 can also be adjusted. For example Figure 3 、 4 As shown in FIGS. 5 and 11, a rubber sheet 9 with elasticity is inlaid at the rear end of the inner lamp housing 5. A U-shaped connecting frame 12 is provided at the rear side of the inner lamp housing 5. The front end of the U-shaped connecting frame 12 penetrates through the rubber sheet 9 and is fixedly connected to the rear side of the reflector 13. The rubber sheet 9 has elasticity, so that the U-shaped connecting frame 12 can rotate without affecting the sealing performance of the inner lamp housing 5.

[0061] An adjusting shaft 22 penetrating through the U-shaped connecting frame 12 is provided on the U-shaped connecting frame 12. Fixing plates 8 installed on the rear side of the inner lamp housing 5 are provided at both ends of the adjusting shaft 22. A second motor 24 is fixedly provided on one of the fixing plates 8. One end of the adjusting shaft 22 penetrates through the fixing plate 8 and is fixedly connected to the output shaft of the second motor 24. The second motor 24 is arranged at the output end of the vehicle computer 6. A vehicle height sensor is provided at the input end of the vehicle computer 6, and can automatically adjust the irradiation angle of the lighting component 3 according to the height of the vehicle body.

[0062] The motor two 24 can drive the adjusting shaft 22 to rotate, and then drive the U-shaped connecting frame 12 to rotate. The U-shaped connecting frame 12 extends into the inner lamp housing 5 and controls the angle of the lighting component 3 by rotation, thereby controlling the irradiation angle of the light. The irradiation angle determines the irradiation distance of the vehicle lamp. The low beam irradiation distance of this vehicle lamp can be adjusted within the range of 30 - 45m, and the brightness is about 3200 lumens. If the suspension of the vehicle can be lifted or lowered, the vehicle height sensor can sense the height of the vehicle body, and based on this, control the motor two 24 through the vehicle computer 6 to automatically adjust the irradiation angle of the lighting component 3, so that the irradiation distance of the lighting component 3 is consistent with the vehicle body height. In addition to automatic adjustment, the driver can also adjust the irradiation angle of the lighting component 3 according to his own habits.

[0063] If the irradiation angle is far enough in the low beam state of the vehicle, when the high beam is turned on at this time, the irradiation distance will become even farther, which will have an adverse impact on oncoming vehicles, such as Figures 10-13 As shown, another fixed plate 8 is fixedly provided with a sleeve 25. An annular resistor 27 is embedded on the inner wall of the sleeve 25. The other end of the adjusting shaft 22 extends into the sleeve 25. An electrode piece 26 is embedded at the outer end of the adjusting shaft 22. The outer end of the electrode piece 26 contacts the inner side of the annular resistor 27. The electrode piece 26 and the annular resistor 27 are both arranged at the input end of the vehicle computer 6. Different contact positions between the electrode piece 26 and the annular resistor 27 indicate different irradiation angles of the lighting component 3.

[0064] When adjusting the irradiation angle of the lighting component 3, the adjusting shaft 22 will rotate and the electrode piece 26 will rotate synchronously. During the rotation of the electrode piece 26, it contacts the annular resistor 27. Since the irradiation angle of the lighting component 3 is different, the contact position between the electrode piece 26 and the annular resistor 27 will be different, and the resistance value in the circuit will be different. Therefore, the irradiation angle of the lighting component 3 can be reflected by the electrode piece 26 and the annular resistor 27. Based on this, the vehicle computer 6 controls the magnetic force of the electromagnet 702, and then controls the irradiation distance after the high beam is turned on, so that the farther the irradiation distance in the low beam state of the lighting component 3, the smaller the increase amplitude of the irradiation distance after the high beam is turned on, and vice versa. That is to say, when the irradiation distance in the low beam state is far enough due to the angle of the lighting component 3, when the high beam is turned on again, the increase in the irradiation distance of the lighting component 3 is relatively limited. In this way, it is avoided that the irradiation distance of the vehicle lamp is too far and affects oncoming vehicles. The irradiation distance of the high beam of this vehicle lamp can vary within 90 - 130m, and the brightness after the high beam is turned on is about 4000 - 4500 lumens.

[0065] After adjusting the irradiation angle of the lighting component 3, the lighting component 3 is suspended inside the inner lamp housing 5 as a whole without any support, and is only fixed by the adjusting shaft 22 and the motor two 24, and the load they bear is relatively large, such asFigure 4 , 5 As shown in Figures 11 and 13, an arc-shaped plate 11 is provided on the inner wall of the outer lamp housing 1 through bolts. A slider is provided on the front side of the arc-shaped plate 11 through an arc-shaped slide rail. Two extension beams 10 are fixedly provided on the front side of the slider. The front ends of the extension beams 10 are fixedly connected to the rear ends of the U-shaped connection brackets 12.

[0066] A counterweight 21 is provided between the two extension beams 10. Slots are formed at the top and bottom ends of the counterweight 21. The two extension beams 10 are respectively inserted into the two slots. The slots enable the counterweight 21 to move along a straight line;

[0067] An adjusting rod 23 passing through the counterweight 21 is provided on the counterweight 21. The adjusting rod 23 is threadedly connected to the counterweight 21. Therefore, when the adjusting rod 23 rotates, the counterweight 21 will move. A first motor 20 is fixedly provided on the front side of the slider. The rear end of the adjusting rod 23 is fixedly connected to the output shaft of the first motor 20. The front end of the adjusting rod 23 is movably connected to the U-shaped connection bracket 12 through a bearing. The first motor 20 is provided at the output end of the vehicle-mounted computer 6.

[0068] An extension beam 10 is provided at the rear side of the U-shaped connection bracket 12. The extension beam 10 can also rotate around the adjusting shaft 22. The extension beam 10, the U-shaped connection bracket 12, and the lighting assembly 3 connected to one end of the U-shaped connection bracket 12 can be regarded as a lever with the adjusting shaft 22 as the fulcrum. The lighting assembly 3 is located at the front end of the lever. When the angle of the lighting assembly 3 is adjusted, the angle of the lighting assembly 3 is also reflected by the electrode piece 26 and the ring resistor 27. Based on this, the first motor 20 is controlled to rotate. The first motor 20 drives the adjusting rod 23 to rotate, and the counterweight 21 slides on the extension beam 10, thereby adjusting the force arm of the counterweight 21, and further making the two ends of the lever as balanced as possible. After the lever is balanced, the loads borne by the second motor 24 and the adjusting shaft 22 will be smaller, reducing the pressure on the two.

[0069] The working principle of this vehicle lamp is as follows: The lighting component 3 is located inside the inner lamp housing 5 and can emit light for illumination. During use, the vehicle can adjust the irradiation angle of the lighting component 3 according to the vehicle body height or the driver's habit. At the same time, it can also automatically control the high and low beams according to the road conditions during driving. The magnetic force of the electromagnet 702 pulls the traction wire 18 and drives the light shielding plate 29 to flip, thereby switching between high and low beams. Moreover, the magnitude of the magnetic force of the electromagnet 702 is proportional to the increase amplitude of the irradiation distance when the high beam is turned on. The electrode plate 26 and the annular resistor 27 can reflect the irradiation angle and irradiation distance of the lighting component 3 in the low beam state. The vehicle computer 6 can control the magnitude of the magnetic force of the electromagnet 702 based on this, and then control the increase amplitude of the irradiation distance after the high beam is turned on, avoiding the over-long irradiation distance of the vehicle lamp from affecting oncoming vehicles. At the same time, the electronic structure magnetic force component 7 for controlling the switching between high and low beams is located outside the inner lamp housing 5, which has less impact on the lighting component 3 during use and is more convenient for maintenance.
