Description

Technical Field

[0001] This invention relates to the automotive field, and more specifically, to a vehicle light. Background Technology

[0002] Currently, aftermarket projector headlights typically consist of: a heat dissipation substrate, a low beam source mounted on the upper surface of the substrate, a high beam source mounted on the lower surface, a solenoid valve cutter, and a beam-emitting lens. The low beam exits from the lower half of the lens, while the high beam exits from the upper half. The solenoid valve drives the cutter to rotate, thus adjusting the high and low beams. The disadvantage of this type of projector headlight is that the low and high beam LEDs are very close together, sometimes even overlapping in projection on the heat dissipation substrate, resulting in poor heat dissipation. If the substrate is made thicker to improve heat dissipation, it will affect the high beam's light output efficiency. Furthermore, the overall brightness of this type of projector headlight is still insufficient. Therefore, current aftermarket projector headlights struggle to simultaneously achieve good heat dissipation, high light output efficiency, and brightness.

[0003] On the other hand, aftermarket projector headlights are fixed to the sides of the front of the car using bolts or other methods, meaning they are completely stationary relative to the car. However, cars frequently turn left or right, go uphill or downhill, and when the headlights cannot adjust to the car's direction, blind spots can occur. This is especially dangerous in dark conditions, particularly when driving on sharp bends or steep slopes, increasing the risk of traffic accidents. Summary of the Invention

[0004] The present invention aims to overcome at least one of the defects of the prior art and provide a vehicle light that solves the problems of the current aftermarket lens headlights, which are difficult to balance heat dissipation, light output efficiency and brightness at the same time, and the fact that the lens headlights are fixed relative to the car and cannot adapt to changes in the direction of the car, resulting in a large traffic hazard at night. In addition, the vehicle light has a small overall size and is suitable for the aftermarket vehicle light market.

[0005] The technical solution adopted in this invention is as follows:

[0006] A vehicle light, comprising:

[0007] The headlight body includes a heat dissipation substrate, a floodlight source, a spotlight source, and a supplementary light source disposed on the same side of the heat dissipation substrate, a light-cutting mechanism for switching between high and low beams, a light-emitting lens for emitting light, and a module housing that is packaged in conjunction with the heat dissipation substrate; the light-emitting lens is provided with a first lens portion for emitting light from the floodlight source, a second lens portion for emitting light from the spotlight source, and a third lens portion for emitting light from the supplementary light source, and the supplementary light source is disposed on the module housing;

[0008] A fixed bracket is movably connected to the module housing;

[0009] A follower-up adapter mechanism is used to movably connect the fixed bracket and the module housing; the follower-up adapter mechanism includes a follower-up adapter bracket that is rotatably connected to both the fixed bracket and the module housing, and a drive device for driving the module housing and / or the follower-up adapter bracket to rotate;

[0010] The follower adapter is rotatably connected to the fixed bracket around a first rotating axis, and the module housing is rotatably connected to the follower adapter around a second rotating axis. The first rotating axis and the second rotating axis are set at an angle. The driving device includes a first driving mechanism for driving the follower adapter to rotate around the first rotating axis and a second driving mechanism for driving the module housing to rotate around the second rotating axis.

[0011] In one embodiment, the floodlight source includes a first LED emitter and a first light-collecting component disposed above the first LED emitter to collect light from the first LED emitter, and the spotlight source includes a second LED emitter and a second light-collecting component disposed above the second LED emitter to collect light from the second LED emitter. Both the floodlight source and the spotlight source are located on the upper surface of the heat dissipation substrate.

[0012] In one embodiment, the light-cutting mechanism includes a light-cutting blade and a solenoid valve for driving the light-cutting blade to change position, wherein the light-cutting blade is a double-arched light-cutting blade.

[0013] In one embodiment, the double-arc cutter includes a first cutter and a second cutter, wherein the first cutter is used to cut the floodlight source into a near beam pattern with a distinct cutoff line, and the second cutter is used to cut the spotlight source into a far beam pattern with a distinct cutoff line.

[0014] In one embodiment, the first rotating shaft is arranged perpendicular to the second rotating shaft.

[0015] In one embodiment, the first driving mechanism includes a rotating shaft passing through the fixed bracket and the follower adapter bracket, a first transmission gear fixedly connected to the rotating shaft, and a first motor driving the first transmission gear to rotate. The output shaft of the first motor is provided with a first motor gear meshing with the first transmission gear. The rotating shaft is rotatably connected to the fixed bracket and fixedly connected to the follower adapter bracket.

[0016] In one embodiment, the fixed bracket is provided with a motor base for supporting the first motor and a base cover that cooperates with the motor base and is used to encapsulate the first motor.

[0017] In one embodiment, the second driving mechanism includes a ball head disposed on the follower adapter bracket, a groove disposed on the module housing and engaging with the ball head, a second transmission gear fixedly connected to the module housing, and a second motor driving the second transmission gear to rotate, wherein the output shaft of the second motor is provided with a second motor gear meshing with the second transmission gear; or, the second driving mechanism includes a ball head disposed on the module housing, a groove disposed on the follower adapter bracket and engaging with the ball head, a second transmission gear fixedly connected to the module housing, and a second motor driving the second transmission gear to rotate, wherein the output shaft of the second motor is provided with a second motor gear meshing with the second transmission gear; or, the second driving mechanism includes a rotating shaft movably passing through the follower adapter bracket, a shaft hole disposed on the module housing and engaging with the rotating shaft, a second transmission gear fixedly connected to the module housing, and a second motor driving the second transmission gear to rotate, wherein the output shaft of the second motor is provided with a second motor gear meshing with the second transmission gear.

[0018] In one embodiment, the headlight body further includes a lens bracket for mounting a light-emitting lens, and the lens bracket is provided with a limiting part for limiting the rotation of the headlight body.

[0019] In one embodiment, the driving device further includes a driving plate electrically connected to both the first driving mechanism and the second driving mechanism, and the vehicle light further includes a direction sensor electrically connected to the driving plate.

[0020] Compared with the prior art, the beneficial effects of the present invention include at least the following:

[0021] In this technical solution, both the floodlight and the spotlight are located on the upper surface of the heat dissipation substrate. The two light sources can be spaced far apart, and the thickness of the heat dissipation substrate can be increased to facilitate heat dissipation for both light sources. The floodlight emits a wide range of light through the first lens, while the spotlight emits high-brightness light through the second lens. Most of the light from both the floodlight and spotlight can be fully utilized. When low beam effect is required, the light-cutting mechanism is located in the optical path of the floodlight and spotlight to cut the tangent and achieve low beam illumination. When high beam effect is required, the light-cutting mechanism moves out of the optical path of the floodlight, spotlight, and supplementary light source to achieve high beam illumination. During low beam illumination, the light-cutting mechanism has very little obstruction to the light from the floodlight and spotlight, resulting in a wide illumination range, high brightness, and high overall light output efficiency of the headlight. Furthermore, this technical solution also adds a supplementary light source and a third lens section for emitting supplementary light rays, which can further enhance the output brightness of the floodlight source and the focused light source, increase the brightness of the vehicle headlight, and improve the utilization rate of the entire light-emitting lens. Therefore, this technical solution takes into account heat dissipation, light output efficiency, and brightness.

[0022] Furthermore, the headlight in this technical solution can be locked and installed on the vehicle using a fixed bracket. A follower-type adapter mechanism connects the headlight body to the fixed bracket, and a drive device rotates the headlight body and / or the follower-type adapter, allowing the headlight body to rotate relative to the fixed bracket. This enables the headlight body to rotate flexibly relative to the vehicle, allowing for timely and rapid adaptive adjustments when the vehicle turns or goes uphill or downhill, maintaining good alignment with the vehicle's direction, avoiding blind spots, improving driving visibility, and especially ensuring driving safety in dark environments. Specifically, when the first drive mechanism drives the follower-type adapter to rotate, the headlight body can rotate around a first axis. When the second drive mechanism drives the headlight body to rotate, it can rotate around a second axis. The angle between the first and second axes allows the headlight body to adapt to lateral swaying during turns and pitching motion when going uphill or downhill, ensuring driving safety and reducing traffic accidents.

[0041] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the invention. To better illustrate the following embodiments, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product dimensions; it is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0042] like Figures 1-3 The vehicle light shown includes:

[0043] The headlight body 10 includes a heat dissipation substrate 11, a floodlight source 12, a spotlight source 13 and a supplementary light source 14 disposed on the same side of the heat dissipation substrate 11, a light-cutting mechanism 15 for switching between high and low beam functions, a light-emitting lens 16 for emitting light, and a module housing 17 that is packaged in conjunction with the heat dissipation substrate 11; the light-emitting lens 16 is provided with a first lens portion 161 for emitting light from the floodlight source 12, a second lens portion 162 for emitting light from the spotlight source 13, and a third lens portion 163 for emitting light from the supplementary light source 14, and the supplementary light source 14 is disposed on the module housing 17;

[0044] The fixed bracket 20 is movably connected to the module housing 17;

[0045] The follower-transfer mechanism 30 is used to movably connect the fixed bracket 20 and the module housing 17; the follower-transfer mechanism 30 includes a follower-transfer bracket 31 that is rotatably connected to both the fixed bracket 20 and the module housing 17, and a drive device 32 for driving the module housing 17 and / or the follower-transfer bracket 31 to rotate.

[0046] The follower adapter 31 is rotatably connected to the fixed bracket 20 around the first rotating axis, and the module housing 17 is rotatably connected to the follower adapter 31 around the second rotating axis. The first rotating axis and the second rotating axis are set at an angle. The driving device 32 includes a first driving mechanism 321 that drives the follower adapter 31 to rotate around the first rotating axis, and a second driving mechanism 322 that drives the module housing 17 to rotate around the second rotating axis.

[0047] In this embodiment, both the floodlight 12 and the spotlight 13 are disposed on the upper surface of the heat dissipation substrate 11. The two light sources can be spaced far apart, and the thickness of the heat dissipation substrate 11 can be increased, which is beneficial to the heat dissipation of the two light sources. The floodlight 12 emits light with a wide angle range through the first lens section 161, and the spotlight 13 emits high-brightness light through the second lens section 162. Most of the light from the floodlight 12 and the spotlight 13 can be fully utilized. When a low beam effect is to be achieved, the light cutting mechanism 15 is located in the optical path of the floodlight 12 and the spotlight 13 and cuts the tangent to achieve a low beam illumination effect. When a high beam effect is to be achieved, the light cutting mechanism 15 moves out of the optical path of the floodlight 12, the spotlight 13 and the supplementary light source 14 to achieve a high beam illumination effect. When illuminating with low beam, the light cutting mechanism 15 blocks very little light from the floodlight 12 and the spotlight 13, resulting in a wide illumination range, high brightness and high light output efficiency of the entire vehicle headlight. Furthermore, this embodiment also includes a supplementary light source 14 and a third lens section 163 for emitting supplementary light rays, which can further enhance the brightness of the floodlight source 12 and the spotlight source 13, increase the brightness of the vehicle headlight, and improve the utilization rate of the entire light-emitting lens 16. Therefore, this embodiment takes into account heat dissipation, light emission efficiency, and brightness.

[0048] In addition, the headlight of this embodiment can be locked and installed on the car by the fixed bracket 20, and the headlight body 10 is movably connected to the fixed bracket 20 by the follower adapter 30. The headlight body 10 and / or the follower adapter 31 are driven to rotate by the drive device 32, so that the headlight body 10 can rotate relative to the fixed bracket 20. Thus, the headlight body 10 can rotate flexibly relative to the car. When the car turns or goes up or down a slope, it can make timely and rapid adaptive adjustments to keep in line with the direction of the car body, avoid blind spots, improve the driving visual experience, and especially ensure driving safety in dark environments. Specifically, when the first drive mechanism 321 drives the follower adapter 31 to rotate, the headlight body 10 can rotate around the first axis. When the second drive mechanism 322 drives the headlight body 10 to rotate, the headlight body 10 can rotate around the second axis. By setting the first axis and the second axis at an angle, the headlight body 10 can be adapted to swing left and right when the car turns and pitch when going up or down slopes, thus ensuring driving safety and reducing the occurrence of traffic accidents.

[0049] like Figure 4 As shown, the floodlight source 12 in this embodiment includes a first LED light emitter 121 and a first light-collecting member 122 covering the first LED light emitter 121 to collect light from it. The spotlight source 13 includes a second LED light emitter 131 and a second light-collecting member 132 covering the second LED light emitter 131 to collect light from it. Both the floodlight source 12 and the spotlight source 13 are located on the upper surface of the heat dissipation substrate 11. Therefore, making the heat dissipation substrate 11 thicker will not affect the utilization rate of the floodlight source 12 and the spotlight source 13. The spacing between the floodlight source 12 and the spotlight source 13 can be larger than that of existing car lights, and the heat dissipation substrate 11 can also be thicker, thereby ensuring both the light output efficiency and heat dissipation effect of the floodlight source 12 and the spotlight source 13. In this embodiment, the first light-collecting element 122 and the second light-collecting element 132 are both reflectors. The first LED light-emitting element 121 is located at the focal position of the first light-collecting element 122, and the second light-emitting element is located at the focal position of the second light-collecting element 132.

[0050] The supplementary light source 14 described in this embodiment is a laser module and / or an LED module. The laser module and LED module can be commercially available conventional structures. For example, the laser module can be a transmissive laser module or a reflective laser module. A transmissive laser module includes a housing, a laser disposed within the housing, a focusing lens, a phosphor sheet, and a light-collecting lens group arranged sequentially along the laser beam path. The difference between a reflective laser module and a transmissive phosphor module is that a light guide guides the laser beam to the phosphor sheet, which then reflects the laser beam back. The LED module includes an LED emitter and a light-collecting lens.

[0051] Furthermore, in this embodiment, there are two supplementary light sources 14, and correspondingly, two third lens sections 163. The first lens section 161 and the second lens section 162 are the same size, and the third lens section 163, the first lens section 161, and the second lens section 162 are arranged closely together. The first lens section 161, the second lens section 162, and the third lens section 163 are integrally formed, reducing processing steps, improving processing accuracy, and facilitating assembly. One of the two supplementary light sources 14 can be a laser module and the other an LED module, or both can be LED modules, or both can be laser modules. In other embodiments, the number of supplementary light sources 14 can be one or three, and the number of third lens sections corresponds to the number of supplementary light sources.

[0052] Furthermore, using a plane parallel to the surface of the heat dissipation substrate 11 and passing through the vertices of the first lens section 161 and the second lens section 162 as a reference plane, the area of ​​the curved surfaces of the first lens section 161 and the second lens section 162 located below the reference plane is greater than the area of ​​the curved surfaces located above the reference plane. Using a plane parallel to the surface of the heat dissipation substrate 11 and passing through the vertices of the third lens section 163 as a second reference plane, the area of ​​the curved surfaces of the third lens section 163 located above the second reference plane is greater than the area of ​​the curved surfaces located below the second reference plane. This ensures sufficient light output efficiency for the floodlight source, the focused light source, and the supplementary light source. The vertices of the first lens section 161, the second lens section 162, and the third lens section 163 refer to the protrusions located at the outermost edges of the curved surfaces of these lens sections in the light output direction of the headlight.

[0053] To improve heat dissipation, the headlight body 10 of this embodiment also includes a heat dissipation assembly 18, which includes a heat dissipation heat pipe 181 disposed on a heat dissipation base plate 11, a heat dissipation fin 182 connected to the heat dissipation heat pipe 181, and a heat dissipation fan 183 installed at the rear of the headlight.

[0054] Furthermore, in this embodiment, the module housing 17 has a hollow interior and a fan 184 is installed inside. The fan 184 is tilted relative to the substrate 11, and the side of the fan 184 closer to the light-emitting lens 16 is higher than the side away from the light-emitting lens 16. Furthermore, in this embodiment, the cooling fan 183 is used to blow airflow into the headlight body 10, and the fan 184 is used to exhaust airflow outside the headlight 10. The tilted design of the fan 184 is more conducive to the dissipation of internal heat.

[0055] like Figure 5 As shown, the light cutting mechanism 15 of this embodiment includes a light cutting blade and a solenoid valve 153 for driving the light cutting blade to change position. The light cutting blade is a double-arc-shaped light cutting blade.

[0056] Specifically, the double-arc cutter includes a first cutter 151 and a second cutter 152. The first cutter 151 is used to cut the floodlight source 12 into a near beam with a distinct cutoff line, and the second cutter 152 is used to cut the spotlight source 13 into a far beam with a distinct cutoff line.

[0057] This embodiment is illustrated using the example of the first rotating axis being perpendicular to the second rotating axis. The headlight body 10 rotates around the first rotating axis to achieve pitch swing of the headlight body 10, and rotates around the second rotating axis to achieve left and right swing of the headlight body 10.

[0058] like Figures 6-7 Combination Figure 2 , Figure 3 As shown, in this embodiment, the first driving mechanism 321 includes a rotating shaft 3211 passing through the fixed bracket 20 and the follower adapter 31, a first transmission gear 3212 fixedly connected to the rotating shaft 3211, and a first motor 3213 driving the first transmission gear 3212 to rotate. The output shaft of the first motor 3213 is provided with a first motor gear meshing with the first transmission gear 3212. The rotating shaft 3211 is rotatably connected to the fixed bracket 20, and the rotating shaft 3211 is fixedly connected to the follower adapter 31. When pitch and oscillation are required, the first motor 3213 drives the first motor gear to rotate, which in turn drives the first transmission gear 3212 to rotate. Since the first transmission gear 3212 is fixedly connected to the rotating shaft 3211, and the rotating shaft 3211 is fixedly connected to the follower adapter bracket 31, which is rotatably connected to the fixed bracket, the follower adapter bracket 31 can rotate around the rotating shaft 3211, thus achieving the pitch and oscillation of the headlight. The forward and reverse rotation of the first motor 3213 is used to achieve the upward and downward tilt of the headlight, respectively. In this embodiment, the rotating shaft 3211 is the first rotating shaft.

[0059] To ensure that the follower adapter bracket 31 can connect better with the fixed bracket 20 without the entire headlight occupying additional space, and to allow the headlight size to meet the requirements of the aftermarket headlight market, the follower adapter bracket 31 in this embodiment includes a first adapter portion 311 and a second adapter portion 312 arranged in a stepped manner. A concave block 40 for accommodating the first adapter portion 311 is provided on one side of the top of the fixed bracket 20. The concave block 40 and the second adapter portion 312 are respectively located on two opposite sides of the fixed bracket 20. In this embodiment, the height of the concave block 40 and the first adapter portion 311 does not exceed the height of the fixed bracket 20, so only the required height of the original fixed bracket 20 needs to be reserved on the vehicle body before installation. The pivot member 3211 passes through the concave block 40 and the first adapter portion 311. The pivot member 3211 is rotatably connected to the concave block 40, i.e., the fixed bracket 20, and is fixedly connected to the first adapter portion 311, i.e., the follower adapter bracket 31. In this embodiment, the recessed portion of the concave block 40 is fitted into the first adapter portion 311, which facilitates the installation of the pivot component 3211, while the inlay structure saves more space. Furthermore, the first adapter portion 311 and the second adapter portion 312 are arranged in a stepped configuration, with the concave block 40 and the second adapter portion 312 located on opposite sides of the fixed bracket 20. This design avoids the fixed bracket 20 by allowing the follower adapter bracket 31 to pass over it, similar to embedding the top of the fixed bracket 20 into the middle of the follower adapter bracket 31. This improves the space utilization of the top of the fixed bracket 20 and avoids occupying extra space for installing the vehicle light of this embodiment.

[0060] like Figures 6-9 As shown, to make the headlight pitch and sway more stable, in this embodiment, there are two sets of the first motor 3213 and the first transmission gear 3212. The two sets of the first transmission gear 3212 are respectively connected to the two opposite ends of the rotating shaft 3211, and the two sets of the first motor 3213 are driven synchronously. Furthermore, the two sets of the first motor 3213 are connected to the fixed bracket 20 and located above the headlight body 10 near the rear. This position has ample space, which can be fully utilized to avoid occupying additional aftermarket space. Specifically, the fixed bracket 20 is provided with a motor base 51 for supporting the first motor 3213, and a base cover 52 that cooperates with the motor base 51 and encapsulates the first motor 3213, preventing the first motor 3213 from being exposed. This not only results in a neat and simple appearance but also provides better protection for the first motor 3213. Furthermore, the middle of both the motor base 51 and the base cover 52 has a clearance design for the concave block 40.

[0061] like Figure 10-12As shown, the second drive mechanism 322 includes a ball head 3221 disposed on the follower adapter bracket 31, a groove 171 disposed on the module housing 17 and engaging with the ball head 3221, a second transmission gear 3222 fixedly connected to the module housing 17, and a second motor 3223 driving the second transmission gear 3222 to rotate. The output shaft of the second motor 3223 is provided with a second motor gear meshing with the second transmission gear 3222. The ball head 3221 and the groove 171 engage to restrict the degrees of freedom of the headlight body 10, allowing the headlight body 10 to rotate along the second axis. In this embodiment, the second axis is an axis passing through the center of the ball head 3221 and perpendicular to the first axis.

[0062] In other embodiments, the second drive mechanism may include a ball head on the module housing, a groove on the follower adapter bracket that mates with the ball head, a second transmission gear fixedly connected to the module housing, and a second motor that drives the second transmission gear to rotate. The output shaft of the second motor is provided with a second motor gear that meshes with the second transmission gear. Alternatively, in other embodiments, a rotating shaft and a shaft hole may be used instead of the ball head and groove. In this case, the second drive mechanism may include a rotating shaft that movably passes through the follower adapter bracket, a shaft hole on the module housing that mates with the rotating shaft, a second transmission gear fixedly connected to the module housing, and a second motor that drives the second transmission gear to rotate. The output shaft of the second motor is provided with a second motor gear that meshes with the second transmission gear. In this case, the rotating shaft and the second rotating shaft coincide.

[0063] In this embodiment, both the first transmission gear 3212 and the second transmission gear 3222 are sector gears. Compared with the traditional standard round gears, the sector structure design of this embodiment can save more space while meeting the rotation requirements, so as to meet the size requirements of the vehicle lights.

[0064] like Figures 13-15 As shown, in order to limit the rotation angle of the headlight when turning left, right, or downward, the headlight body 10 described in this embodiment is provided with a limiting part for limiting the rotation of the headlight body 10. Specifically, the headlight body 10 also includes a lens bracket 19 for mounting the light-emitting lens 16, and the limiting part is provided on the lens bracket 19. The limiting part is a protrusion 191 provided on the lens bracket 19, that is, the left, right, and lower sides of the lens bracket 19 are provided with protrusions 191 for limiting. When the headlight rotates to the left, right, or downward to the limit position, the corresponding protrusion 191 abuts against the fixed bracket 20 to limit the rotation. The protrusion 191 can be configured to be integrally formed with the lens cover, that is, the lens bracket 19 is made into a structure with protrusions 191 on the outer shell, which facilitates assembly.

[0065] like Figure 16 As shown, in this embodiment, when the headlight rotates upward to its limit position, the top of the second adapter 312 abuts against the fixed bracket 20 to achieve a limiting function. That is, the second adapter 312 itself has a certain limiting function, so this embodiment does not need to set an additional limiting part to restrict the upward movement of the headlight.

[0066] like Figure 4 , Figure 17 As shown, the driving device 32 in this embodiment further includes a driving plate 323, which is electrically connected to both the first driving mechanism 321 and the second driving mechanism 322. The headlight also includes a direction sensor 60 electrically connected to the driving plate. When the car turns or goes uphill or downhill, the direction sensor 60 can detect the car's turning or uphill / downhill movement, thereby transmitting a signal to the driving plate. The driving plate then drives the corresponding driving mechanism to operate, thereby causing the headlight body 10 to rotate, thus achieving adaptive steering of the headlight. Specifically, the direction sensor 60 in this embodiment is a gyroscope.
