Description

Technical Field

[0001] The utility model relates to the technical field of automobile lighting, and more specifically to a follow-up steering lamp. Background Art

[0002] Most of the existing automobile headlights on the market have low beams set above the heat dissipation substrate and high beams set below the heat dissipation substrate, and the light type switching of high and low beams is achieved through the solenoid valve shading sheet. The disadvantages of this type of automobile headlights are: the low beam light source and the high beam light source are very close, the heat of the low beam light source and the high beam light source is too concentrated, the heat dissipation effect of the headlight is not good, and the power cannot be made larger. If the heat dissipation substrate is made thicker for the heat dissipation effect, the light of the high and low beam light sources will have a greater loss, and the brightness of the headlight will be affected. Therefore, it is difficult to take into account both the heat dissipation effect and the brightness at the same time; in addition, when the low beam is illuminated, a lot of light is blocked by the shading sheet, and only the lower half of the light-emitting lens emits light, the light emission efficiency is not high, and the brightness of the headlight is low.

[0003] In addition, most of the existing car headlights on the market do not have automatic steering functions, and their illumination direction is always consistent with the car body. When the vehicle is turning or going uphill or downhill, it is easy to have blind spots in the field of vision, especially in rainy and foggy weather or in dark environments without auxiliary lighting from road lamps.

DETAILED DESCRIPTION

[0036] The drawings of the present invention are only used for illustrative purposes and cannot be construed as limiting the present invention. In order to better illustrate the following embodiments, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product; for those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted.

[0037] Example 1

[0038] like Figure 1 , Figure 2 As shown, this embodiment discloses a follow-up steering lamp, including a mounting bracket 200, a lens lamp 100 movably connected to the mounting bracket 200, and a driving mechanism 300 for driving the mounting bracket 200 or the lens lamp 100 to make the lens lamp 100 rotate relative to the mounting bracket 200, the driving mechanism 300 is arranged on the lens lamp 100 or on the mounting bracket 200, the lens lamp 100 includes a substrate 110, a first light source 120 and a second light source 130 arranged on the upper surface of the substrate 110, and a light emitting lens 120 for emitting light. The light emitting lens 140 includes a first lens portion 141 for emitting light from the first light source 120 and a second lens portion 142 for emitting light from the second light source 130. The first lens portion 141 and the second lens portion 142 are arranged along the width direction of the lens headlight 100. The width of the light emitted by the first lens portion 141 is greater than the width of the light emitted by the second lens portion 142 and the brightness of the light emitted by the first lens portion 141 is lower than the brightness of the light emitted by the second lens portion 142.

[0039] To make the description clearer, the brightness, width, length direction and width of the emitted light are explained. The brightness of the emitted light described in this application refers to the illumination of the emitted light, and the width of the emitted light refers to the distance between the left and right sides of the light emitting area when the light is emitted forward. The direction parallel to the light emitting direction of the light emitting lens 140 is the length direction, represented by x; the direction parallel to the surface of the substrate 110 and perpendicular to the length direction is the width direction, represented by y, as shown in FIG. Figure 1 In addition, the head portion in this embodiment refers to the side where the light-emitting lens 140 is located, and the tail portion refers to the other side opposite to the side where the light-emitting lens 140 is located.

[0040] In this embodiment, a mounting bracket 200 is provided on the lens headlight 100 and the lens headlight 100 is movably connected to the mounting bracket 200. The lens headlight 100 and the mounting bracket 200 can rotate relative to each other through a driving mechanism 300. When the mounting bracket 200 is installed on a car, the driving mechanism 300 can rotate the lens headlight 100 relative to the car body, thereby realizing adaptive adjustment of the lens headlight 100 and realizing the follow-up function of the lens headlight 100. Furthermore, since the first light source 120 and the second light source 130 are both arranged on the upper surface of the substrate 110, the thickness of the substrate 110 can be increased, and the heat of the first light source 120 and the second light source 130 can be quickly transferred to the entire substrate 110, and the first light source 120 and the second light source 130 can be better separated, which is more conducive to heat dissipation. The light emitted by the first light source 120 through the first lens portion 141 has a wide irradiation range, and the light emitted by the second light source 130 through the second lens portion 142 has high brightness. Therefore, the emitted light has both a large-angle irradiation range and a high-brightness lighting effect. Since the first light source 120 and the second light source 130 are both located on the upper surface of the substrate 110, the light cutting mechanism 150 can achieve very little obstruction to the first light source 120 and the second light source 130, and the entire headlight has high light output efficiency. The follow-up steering headlight has the advantages of good heat dissipation effect, wide irradiation range, high lighting brightness, and follow-up steering lighting. When low beam lighting is to be achieved, the light cutting mechanism 150 is located in the optical path of the first light source 120 and the second light source 130, and a small amount of light from the first light source 120 and the second light source 130 is blocked to achieve a low beam lighting effect with a clear cut-off line; when high beam lighting is to be achieved, the light cutting mechanism 150 is moved out of the optical path of the first light source 120 and the second light source 130 to achieve a high beam lighting effect.

[0041] Furthermore, if Figure 1 , Figure 5 As shown, the lens headlight described in this embodiment also includes a driving plate 180, and the control of the driving mechanism 300 is realized by the driving plate 180. The driving plate 180 is also electrically connected to an external mechanism that can detect or sense external signals. When the driving plate 180 receives an external signal, for example, when a signal is received that a left turn is required, the driving plate 180 sends a corresponding instruction to the driving mechanism 300, and the driving mechanism 300 drives the lens headlight 100 to rotate left. For example, when a right turn is required, the opposite instruction is issued. More specifically, the driving plate 180 described in this embodiment is arranged below the substrate 110. More specifically, the driving plate 180 is mounted on the lower surface of the heat dissipation substrate 110. The driving plate 180 also provides current for the operation of the first light source 120 and the second light source 130.

[0042] Furthermore, a protective shell is provided below the driving board 180. The protective shell can play the role of waterproofing, dustproofing, preventing the driving board from being exposed, and making the headlight beautiful.

[0043] Furthermore, in this embodiment, the driving mechanism 300 is used to drive the lens headlight 100 to rotate left and right or up and down relative to the mounting bracket 200, and a connecting component is provided between the mounting bracket 200 and the lens headlight 100 for realizing the rotational movement of the lens headlight 100 relative to the mounting bracket 200. The left and right rotation is suitable for the follow-up adjustment of the car turning, and the up and down rotation is suitable for the follow-up adjustment of the car going uphill and downhill. In this embodiment, the driving mechanism 300 is used to drive the lens headlight 100 to rotate left and right relative to the mounting bracket 200 as an example. In other embodiments, the driving mechanism may also drive the lens headlight 100 to rotate up and down relative to the mounting bracket 200.

[0044] Furthermore, if Figure 3 , Figure 4 As shown, in this embodiment, the connecting assembly includes a connecting member and a mounting hole 420 matched with the connecting member for accommodating the connecting member, and the connecting member is a connecting screw and a connecting rod. More specifically, the connecting member in this embodiment includes a first connecting member and a second connecting member, and the first connecting member is a machine screw 411, and the machine screw 411 can make the connection between the mounting bracket 200 and the lens headlight 100 tighter, ensuring that the lens headlight 100 is not easily rotated due to the vibration of the car during the driving process of the car, and there is no need to set a fastener at the end to prevent the mounting bracket 200 and the lens headlight 100 from being separated. In other embodiments, the first connecting member can also be a connecting rod. In this embodiment, the second connecting member is a connecting rod 412.

[0045] Furthermore, in this embodiment, the mounting holes 420 include two, which are respectively arranged at the top and bottom of the mounting bracket 200, one end of the connector is arranged in the mounting hole 420, and the other end of the connector is directly or indirectly connected to the lens headlight 100. Specifically, in this embodiment, the screw 411 is located in the mounting hole at the top, and the tip of the screw is inserted into the lens headlight 100, the upper end of the connecting rod 412 is located in the lens headlight 100, and the lower end is located in the mounting hole 420 at the bottom, and the middle part of the connecting rod 412 is also provided with a disc-like structure for preventing the connecting rod 412 from falling off. The design of the connector and the mounting hole 420 allows the connector to rotate in the mounting hole, thereby realizing the rotational movable connection between the lens headlight 100 and the mounting bracket 200.

[0046] Furthermore, if Figure 6 , Figure 7As shown, in this embodiment, a transmission member is further provided between the mounting bracket 200 and the lens headlight 100. Specifically, the transmission member is a turbine 500 in this embodiment. The driving mechanism 300 is provided with a worm 310 that matches the turbine 500 and is used to drive the turbine 500 to rotate. The driving structure of the driving mechanism 300 is a motor 320. In other embodiments, the driving structure may also be a solenoid valve or other driving structures. When the motor 320 is driven, the worm 310 will rotate, which may be forward or reverse, thereby driving the turbine 500 to rotate clockwise or counterclockwise, thereby realizing the left or right rotation of the lens headlight 100.

[0047] Furthermore, in this embodiment, an adapter frame 210 is provided on the mounting bracket 200, and the turbine 500 is fixedly mounted on the adapter frame 210. The design of the adapter frame 210 can facilitate the installation of the turbine 500 and avoid the problem of insufficient space in the main frame of the mounting bracket 200. When the turbine 500 rotates, in theory, it will drive the mounting bracket 200 to rotate, but because the mounting bracket 200 is fixedly installed on the car, the mounting bracket 200 itself does not move, and the lens headlight 100 is movably connected to the mounting bracket 200. Because the lens headlight 100 can rotate when the mounting bracket 200 does not move, the follow-up rotation of the lens headlight 100 is achieved, such as Figure 8 The figure shows the status of the follow-up lights in different turning states of the car.

[0048] Furthermore, the light output lens 140 is disposed in a lens sleeve, and the lens sleeve is mounted on the substrate 110 .

[0049] Furthermore, the lens headlight 100 is also provided with a stopper for limiting the steering angle of the lens headlight 100. More specifically, in this embodiment, the stopper includes a first stopper 610 and a second stopper 620, and both are located on the lens sleeve. Figure 8 As shown, when the lens lamp 100 is in the initial position (such as Figure 8 As shown in the left figure), the lens lamp 100 is not in contact with the two stop blocks, and the plane where the mounting bracket 200 is located is perpendicular to the length direction of the lens lamp 100; when the lens lamp 100 needs to be rotated to the left (such as Figure 8 As shown in the middle figure, the lens lamp 100 rotates to the left relative to the mounting bracket 200 under the action of the driving structure 300. When the first limit block 610 on the lens lamp 100 touches the mounting bracket 200, it reaches the limit position of left rotation and stops rotating. When the lens lamp 100 needs to rotate to the right (as shown in the middle figure), the lens lamp 100 rotates to the left relative to the mounting bracket 200. Figure 8As shown in the right figure, the lens lamp 100 rotates to the right relative to the mounting bracket 200 under the action of the driving structure 300. When the second limit block 620 on the lens lamp 100 touches the mounting bracket 200, it reaches the limit position of right rotation and stops rotating. Thus, the left and right rotation limits are realized by the first limit block 610 and the second limit block 620.

[0050] Furthermore, the lens headlight 100 further includes a third light source 160, and the light-emitting lens 140 includes a third lens portion 143 for emitting light from the third light source 160; a plane parallel to the surface of the substrate 110 and passing through the vertices of the first lens portion 141 and the second lens portion 142 is taken as a first reference plane, and the area of ​​the curved surface of the first lens portion 141 and the second lens portion 142 below the first reference plane is greater than the area of ​​the curved surface above the first reference plane; a plane parallel to the surface of the substrate 110 and passing through the vertices of the third lens portion 143 is taken as a second reference plane, and the area of ​​the curved surface of the third lens portion 143 above the second reference plane is greater than the area of ​​the curved surface below the second reference plane. With such a design, the light-emitting efficiency of the first light source 120 and the second light source 130 is higher. The vertices of the first lens portion 141, the second lens portion 142, and the third lens portion 143 described in the technical solution refer to the convex points at the edge of the light-emitting surfaces of the first lens portion 141, the second lens portion 142, and the third lens portion in the length direction of the lens headlight 100. More specifically, in this embodiment, the first lens portion 141 and the second lens portion 142 are of the same size, the first lens portion 141 and the second lens portion 142 are located in the lower half of the light exit lens 140, and the third lens portion 143 is located in the upper half of the light exit lens 140. More specifically, in this embodiment, the number of the third lens portions 143 is 2, which are respectively located above the first lens portion 141 and the second lens portion 142. In other embodiments, the number of the third lens portions 143 may also be 1 or 3 or more.

[0051] Furthermore, the third light source 160 includes a first fill light source 161 and a second fill light source 162 . The first fill light source 161 and the second fill light source 162 may both be LED light sources or both be laser light sources or one may be an LED light source and the other may be a laser light source.

[0052] Furthermore, the first light source 120 includes a first LED illuminator 121 and a first reflector cup 122 for collecting light from the first LED illuminator 121, and the light collection rate of the first reflector cup 122 is greater than 80%; the second light source 130 includes a second LED illuminator 131 and a second reflector cup 132 for collecting light from the second LED illuminator 131, and the collection efficiency of the second reflector cup 132 for the second LED illuminator 131 is greater than 80%. Most of the headlights in the aftermarket are of the following two types: (1) the low-beam light source and the high-beam light source are respectively arranged on the upper surface and the lower surface of the heat dissipation substrate; (2) the light-emitting surfaces of the low-beam light source and the high-beam light source are both facing upward, but the mounting surface of the high-beam light source is lower than the mounting surface of the low-beam light source. The problems with the first type of headlight are the heat dissipation problem and the problem of insufficient light output efficiency of the headlight due to the thickness of the heat dissipation substrate. The second type of headlight has insufficient light output efficiency of the high-beam light source because it needs to meet the requirement that the high-beam reflector cup cannot block the light of the low-beam light source. Some front-mounted headlights are designed with multiple light sources installed on the upper surface of the heat dissipation substrate as low-beam light sources, but the light-collecting panels are mostly 3 or more connected structures, and the light collection efficiency of the light source is very low, usually less than 70%, the light utilization rate is low, and the headlight brightness is not enough. In addition, this method of front-mounted headlights also requires an additional high-beam light source to be installed under the heat dissipation substrate. The collection efficiency of the reflector cup of the headlight of this technical solution is greater than 80%, and can even reach greater than 90%, with high collection efficiency, good heat dissipation effect, and high light brightness.

[0053] The light cutting mechanism 150 includes a shading sheet 151 for forming a low beam light type and a driving member 152 for driving the shading sheet 151 to switch positions. The shading sheet 151 includes a first shading sheet 1511 corresponding to the first light source 120 and a second shading sheet 1512 corresponding to the second light source 130. The first shading sheet 1511 and the second shading sheet 1512 can both cut light into a low beam light type. Furthermore, the light-emitting surfaces of the first LED light-emitting body 121 and the second LED light-emitting body 131 are not higher than the vertices of the first light-shielding sheet 1511 and the second light-shielding sheet 1512 (the vertices of the first light-shielding sheet 1511 and the second light-shielding sheet 1512 refer to the highest points of the transition connection of the light-shielding sheets of different heights of the first light-shielding sheet 1511 and the second light-shielding sheet 1512). With such a design, the light-cutting mechanism 150 can only block a very small amount of light from the first light source 120 and the second light source 130, and the light from the first light source 120 and the second light source 130 can basically be emitted from all the light-emitting surfaces of the first lens portion 141 and the second lens portion 142, and the light-emitting efficiency is very high. Furthermore, the light-shielding sheet 151 described in the present application is an asymmetric structure. In the direction parallel to the width of the lens headlight 100, the length of the first light-shielding sheet 1511 is greater than the length of the second light-shielding sheet 1512, and the weight difference between the two is less than 10%. Fig. 9 As shown, the shading sheet 151 needs to be connected to the driving member 152, and the connection position is generally located in the middle part of the shading sheet 151, that is, the driving part of the driving member 152 used to drive the shading sheet 151 and the connection position of the shading sheet 151 are generally located in the middle part of the shading sheet 151. The above-mentioned asymmetric design can not only keep the shading sheet 151 balanced as a whole, but also reserve enough space for the connection position, and can also better take into account the light effect and cost. If the connection problem between the shading sheet 151 and the driving member 152 and the weight balance problem are ignored, since the brightness of the light emitted by the second light source 130 is higher, the light is more concentrated and the width is narrower, then the area that needs to be blocked is less, so the length of the second shading sheet 1512 can be reduced. However, if the weight difference at both ends of the shading sheet 151 is large, it is difficult to ensure the balance of the shading sheet 151. The asymmetric structural design adopted in this technical solution can simultaneously meet the requirements of assembly, balance and high light efficiency, achieving three goals at one stroke.

[0054] In more detail, the first shading sheet 1511 includes a first arc-shaped sheet 1511a and a second arc-shaped sheet 1511b, and the width of the first arc-shaped sheet 1511a is greater than that of the second arc-shaped sheet 1511b; the second shading sheet 1512 includes a third arc-shaped sheet 1512c and a fourth arc-shaped sheet 1512d, and the width of the third arc-shaped sheet 1512c is greater than that of the fourth arc-shaped sheet 1512d; the first arc-shaped sheet 1511a and the third arc-shaped sheet 1512c have the same width, the second arc-shaped sheet 1511b and the fourth arc-shaped sheet 1512d have the same width, and the first shading sheet 1511 and the second shading sheet 1512 have the same curvature. More specifically, in this embodiment, the first arc piece 1511a is arranged close to the fourth arc piece 1512d, that is, the first arc piece 1511a and the fourth arc piece 1512d are located in the middle of the light cutting piece 151, and the second arc piece 1511b and the third arc piece 1512c are located at both ends of the light shielding piece 151. This design is suitable for the driving mode of the domestic driver sitting in the left driving cabin. For the case where the driver sits in the right driving cabin, the second arc piece 1511b and the third arc piece 1512c can be located in the middle of the light cutting piece 151, and the first arc piece 1511a and the fourth arc piece 1512d are located at both ends of the light cutting piece 151. Furthermore, in this embodiment, the first arc-shaped sheet 1511a and the second arc-shaped sheet 1511b are integrally formed, the third arc-shaped sheet 1512c and the fourth arc-shaped sheet 1512d are integrally formed, and the first light shielding sheet 1511 and the second light shielding sheet 1512 are integrally formed, that is, the light shielding sheet 151 is integrally formed. The integrally formed design facilitates the production, fixing, installation and removal of the light shielding sheet 151.

[0055] Furthermore, the lens lamp 100 further includes a first cooling fan 171 located at the rear of the substrate 110 and a second cooling fan 172 located at the top of the substrate 110, the second cooling fan 172 is located in the heat sink 190, and the third light source 160 is disposed on the heat sink 190. Furthermore, the second cooling fan 172 is disposed obliquely relative to the substrate 110, and a side of the second cooling fan 172 close to the light output lens 140 is higher than a side away from the light output lens 140.

[0056] Furthermore, a fan protection cover is provided on the outer side of the second heat dissipation fan 172 to prevent dust and improve appearance.

[0057] Furthermore, the heat sink 190 is a metal shell structure matched with the placement position of the second heat sink fan 172, which can prevent the internal structure of the lens headlight 100 from being exposed, dust and other impurities from entering the lens headlight 100, and can also improve the aesthetics of the lens headlight 100. In addition, the volume and surface area of ​​the heat sink 190 are much larger than those currently available on the market, and the second heat sink fan 172 and the heat sink 190 cooperate to achieve a significant improvement in the heat dissipation effect.

[0058] like Fig.10 As shown, in this embodiment, the first cooling fan 171 is used to blow air into the lens lamp 100, and the second cooling fan 172 is used to exhaust air to the outside of the lens lamp 100. Due to the presence of the first reflector cup 122 and the second reflector cup 132 inside the lens lamp 100, the position and direction of the airflow of the first cooling fan 171 will change after the airflow is blown into the first reflector cup 122 and the second reflector cup 132. The second cooling fan 172 is tilted toward the heat dissipation substrate 110 and is located at a higher position on the side of the light emitting lens 140, so that the hot air flow inside the lens lamp 100 can be discharged more quickly.

[0059] For example Figure 1 and Figures 11 to 13As shown, the first LED illuminant 121 and the second LED illuminant 131 are respectively mounted on different copper plates, and the copper plates for mounting the first LED illuminant 121 and the second LED illuminant 131 are both mounted on the upper surface of the substrate 110. The lens lamp 100 is also provided with a heat pipe assembly 173, and the heat pipe assembly 173 includes a heat pipe 1731 and a heat sink 1732 connected to the heat pipe 1731, and the heat pipe 1731 is arranged in contact with the upper surface of the copper plate for mounting the first LED illuminant 121 and the second LED illuminant 131. Further, the heat pipe assembly 173 is also provided with a heat sink 1733, and the heat sink 1733 is provided with a groove for accommodating at least a part of the heat pipe 1731; the copper plate is arranged below the heat sink 1733 and is in contact with the heat sink 1733 and / or the heat pipe 1731. With such a design, the heat of the copper plate can be quickly conducted out through the heat pipe 1731 and the heat sink 1733, and the heat dissipation effect is excellent.

Specifically, in this embodiment, the sensing mechanism is a gyroscope 700. When the car turns, the gyroscope can detect that the car is turning, thereby transmitting a signal to the driving plate 180, and the driving plate 180 drives the driving mechanism 300 to work, and the motor 320 works to rotate the screw 310, thereby driving the turbine 500 to rotate, thereby realizing the deflection of the lens lamp 100 relative to the mounting bracket 200.
