Description

Technical Field

[0001] The present application relates to the field of vehicle networking technology, and in particular to a headlight and a vehicle. Background Art

[0002] Intelligent scene interaction has become an important core of the development of automotive lighting in recent years, and can significantly enhance the competitiveness of automotive lighting.

[0003] Currently, headlights in vehicles are used for lighting, and the application scenarios are relatively monotonous. Utility Model Content

[0004] The embodiments of the present application provide a vehicle lamp and a vehicle, aiming to solve the problem that the application scenarios of vehicle lamps are relatively monotonous.

[0005] In the first aspect, the present application provides a headlight, which includes a light-emitting module and a reflector group; the light-emitting module is used to emit light; the reflector group includes a first reflector and a second reflector, and the first reflector and the second reflector are arranged at an interval; the first reflector rotates axially; when the first reflector is in a first position, the first reflector is used to reflect the light emitted by the light-emitting module to the second reflector, and the second reflector is used to reflect the light emitted by the first reflector out of the headlight, and when the first reflector is in a second position, the light emitted by the light-emitting module is emitted out of the headlight.

[0006] In this embodiment, the first reflector is rotatable and can be in a first position or a second position. The headlight can have two states. For example, when the first reflector is in the second position, light emitted by the light-emitting module is directly emitted from the headlight, which can be used for illumination. When the first reflector is in the first position, the light-emitting module can emit light that produces a pattern. The first reflector reflects the light emitted by the light-emitting module, and the second reflector reflects the light reflected from the first reflector out of the headlight, which can also produce a pattern.

[0007] In conjunction with the first aspect, in one possible implementation, when the first reflector is in the first position, the angle between the first reflector and the optical axis of the light-emitting module is 40° to 50°. At this time, light emitted by the light-emitting module can be reflected by the first reflector to the second reflector.

[0008] In conjunction with the first aspect, in one possible implementation, when the first reflector is in the second position, the angle between the first reflector and the optical axis of the light-emitting module is between -7° and -1°. Because the angle between the first reflector and the optical axis of the light-emitting module is between -7° and -1°, the first reflector does not reflect light emitted by the light-emitting module. Light emitted by the light-emitting module is emitted directly from the light-emitting module and exits the vehicle headlight, thereby improving the lighting effect of the light-emitting module.

[0009] With reference to the first aspect, in one possible implementation, when the first reflector is in the first position, the angle formed between the second reflector and the first reflector is 4° to 9°. When the headlight is used in a vehicle, the vehicle is equipped with the headlight. When the headlight projects a pattern, because the angle formed between the second reflector and the first reflector is 4° to 9°, the second reflector can reflect light from the first reflector toward the front of the vehicle.

[0010] With reference to the first aspect, in one possible implementation, when the first reflector is in the first position, the second reflector forms an angle of 6° with the first reflector. When the headlight is used in a vehicle, the vehicle is equipped with one of the above-described headlights. When the headlight projects a pattern, the second reflector forms an angle of 6° with the first reflector, and the second reflector is capable of reflecting light from the first reflector to a position 2m-5m directly in front of the vehicle.

[0011] In combination with the first aspect, in a possible implementation, the angle between the normal of the second reflector and the axial direction of the optical axis of the light-emitting module is 44° to 54°.

[0012] In combination with the first aspect, in a possible implementation, the light-emitting module is a DLP.

[0013] In combination with the first aspect, in a possible implementation, when the first reflector is in the second position, the headlight is used for lighting, and when in the first position, the headlight is also used for projecting a pattern.

[0014] In combination with the first aspect, in a possible implementation, the reflector group also includes a shell, the light-emitting module extends into the shell, the first reflector is hinged to the shell, and the shell is also connected to the second reflector, and the first reflector and the second reflector are spaced apart to form a light outlet.

[0015] In a second aspect, the present application provides a vehicle comprising the vehicle lamp as described in the first aspect.

[0016] In conjunction with the second aspect, in a possible implementation, the vehicle is provided with a headlight. The headlight can provide both illumination and pattern projection, and the pattern projected by the headlight can be projected in the center of the front of the vehicle.

[0029] In order to more clearly illustrate the technical solutions in the embodiments of the present application or the background art, the drawings needed to be used in the embodiments of the present application or the background art will be described below.

[0030] Please refer to Figure 1 and Figure 2 The present application discloses a vehicle, which comprises a vehicle head 10, a vehicle lamp 20 and a companion lamp 30. The vehicle head 10 comprises a left mounting position, a middle position and a right mounting position, the middle position being between the left mounting position and the right mounting position, the vehicle lamp 20 being mounted on one of the left mounting position or the right mounting position, and the companion lamp 30 being mounted on the other of the left mounting position or the right mounting position. Specifically, when the vehicle lamp 20 is mounted on the left mounting position, the companion lamp 30 is mounted on the right mounting position. When the vehicle lamp 20 is mounted on the right mounting position, the companion lamp 30 is mounted on the left mounting position.

[0031] For ease of understanding, the X-axis is defined as the length of the vehicle, the Y-axis is defined as the width of the vehicle, and the Z-axis is defined as the height of the vehicle. The left, middle, and right mounting positions are sequentially arranged along the Y-axis of the vehicle.

[0032] See Figure 3 、 Figure 4 and Figure 5 The headlight 20 includes a light emitting module 21 and a reflector assembly 22. The light emitting module 21 is used to emit light. The light emitted by the light emitting module 21 can be used for illumination and can also form a pattern 21a. In the embodiment provided in this application, the light emitting module 21 is a DLP module (digital light processing, DLP).

[0033] See Figure 6 The light-emitting module 21 includes a first reflector 22a and a second reflector 22b. The first reflector 22a and the second reflector 22b are spaced apart. Specifically, in the Z-axis direction, the first reflector 22a and the second reflector 22b are spaced apart. The first reflector 22a can rotate axially, and the axial direction of the first reflector 22a extends along the Y-axis direction of the vehicle. Specifically, the first reflector 22a can be driven to rotate by a driving member, which can be, but is not limited to, a motor. The first reflector 22a can rotate from a first position to a second position, or from the second position to the first position.

[0034] The headlight 20 has a welcoming state and an illuminating state, which can be switched between the welcoming state and the illuminating state. In the welcoming state, the light module 21 can generate light that forms a pattern 21a. In the illuminating state, the headlight 20 can be used in scenes where the vehicle is driving.

[0035] When the headlight 20 switches from the welcoming state to the lighting state, the first reflector 22a rotates from the first position to the second position; when the headlight 20 switches from the lighting state to the welcoming state, the first reflector 22a rotates from the second position to the first position.

[0036] When the first reflector 22a is in the second position, the light emitted by the light emitting module 21 is directly emitted from the vehicle lamp 20. In the embodiment provided in the present application, when the first reflector 22a is in the second position, the vehicle lamp 20 is used for lighting.

[0037] When the headlight 20 is in the illuminated state and the first reflector 22a is in the second position, the light emitted by the light-emitting module 21 can illuminate the vehicle while it is in motion. For example, when the vehicle is driving at night or in a relatively dark environment, the first reflector 22a does not reflect the light emitted by the light-emitting module 21. In this case, the light emitted by the light-emitting module 21 is emitted directly out of the headlight 20. When the first reflector 22a is in the second position, the angle between the first reflector 22a and the optical axis of the light-emitting module 21 is between -7° and -1°, and the optical axis is aligned with the X-axis. The first reflector 22a is located in front of the light-emitting module 21. Since the angle between the first reflector 22a and the optical axis of the light-emitting module 21 is between -7° and -1° when the first reflector 22a is in the second position, the first reflector 22a does not reflect the light emitted by the light-emitting module 21, and the light emitted by the light-emitting module 21 is emitted directly out of the headlight 20. The optical axis refers to the center line of the light beam emitted by the light emitting module, and is the line through the center of the lens in the light emitting module.

[0038] See Figure 7 When the first reflector 22a is in the first position, the first reflector 22a is used to reflect the light emitted by the light emitting module 21 to the second reflector 22b, and the second reflector 22b is used to reflect the light emitted by the first reflector 22a out of the vehicle lamp 20.

[0039] When the headlight 20 is in the welcoming state and the first reflector 22a is in the first position, the headlight 20 is also configured to project a pattern 21a. For example, when the first reflector 22a is in the first position, the light module 21 emits light that forms the pattern 21a. The light forming the pattern is reflected by the first reflector 22a to the second reflector 22b. The second reflector 22b then reflects the light forming the pattern out of the headlight 20. The light emitted from the headlight 20 is projected onto the ground or a flat surface to form a pattern. When the first reflector 22a is in the first position, the angle between the optical axis of the first reflector 22a and the light module 21 is between 40° and 50°. Specifically, the angle between the optical axis of the first reflector 22a and the light module 21 can be 45°.

[0040] In some embodiments, the angle between the second reflector 22b and the optical axis of the light-emitting module 21 is 36°-46°, and the specific angle between the second reflector 22b and the optical axis of the light-emitting module 21 can be 41°. When the first reflector 22a is in the first position, the angle between the second reflector 22b and the first reflector 22a is 40°-50°. When the headlight 20 is in the welcoming state, the second reflector 22b can reflect light emitted from the first reflector 22a onto the ground in front of the vehicle.

[0041] When the first reflector 22a is located at the first position, the normal line of the first reflector 22a is not coplanar with the normal line of the second reflector 22b, and the axial direction of the first reflector 22a is not parallel to the second reflector 22b.

[0042] In the embodiment provided herein, when the first reflector 22a is in the first position, the second reflector 22b reflects the light pattern out of the headlight 20. If the light pattern is projected onto the ground, the pattern will appear in front of the left or right side of the light-emitting module 21. For example, if the headlight 20 is installed on the left side of the vehicle's front 10, the pattern reflected by the second reflector 22b will appear directly in front of the center of the vehicle's front 10 (the pattern reflected by the second reflector 22b will appear in front of the right side of the light-emitting module 21). For example, if the headlight 20 is installed on the right side of the vehicle's front 10, the pattern reflected by the second reflector 22b will appear directly in front of the center of the vehicle's front 10 (the pattern reflected by the second reflector 22b will appear in front of the left side of the light-emitting module 21).

[0043] Please continue to see Figure 6 The reflector assembly also includes a shell 23, the light-emitting module 21 extends into the shell 23, and the shell 23 is fixedly connected to the light-emitting module 21. The shell 23 is hinged to the first reflector 22a, and the shell 23 is also connected to the second reflector 22b. The first reflector 22a and the second reflector 22b are spaced apart to form a light outlet. Specifically, the axial direction of the first reflector 22a extends along the Y-axis direction of the vehicle. By driving the first reflector 22a to rotate axially, the first reflector 22a can be controlled to switch from the first position to the second position. By driving the first reflector 22a to rotate axially, the first reflector 22a can be controlled to switch from the second position to the first position. The axial direction of the first reflector 22a is perpendicular to the optical axis direction of the light-emitting module 21, and the length direction of the first reflector 22a extends along the Y-axis direction of the vehicle.

[0044] The second reflector 22b can be fixedly connected to the housing 23 or hinged to the housing 23. The length direction of the second reflector 22b is at an angle to the Y-axis direction of the vehicle. The specific connection method of the second reflector 22b and the housing 23 is not particularly limited in this application.

[0045] The headlight 20 is installed at the left side installation position or the right side installation position of the front of the vehicle 10. The first reflector 22a and the second reflector 22b are both located on one side (front) of the light-emitting module 21 along the X-axis direction. The second reflector 22b includes a first end and a second end along the length direction. The first end is closer to the companion light 30 than the second end, and the first end is closer to the companion light 30 than the second end.

[0046] For example, if the headlight 20 is installed in the left mounting position and the companion light 30 is installed in the right mounting position, the first end is closer to the right mounting position than the second end, and the first end is closer to the light-emitting module 21 than the second end, and the second reflector 22b can reflect the light emitted from the first reflector 22a to the center position directly in front of the vehicle head 10. If the headlight 20 is installed in the right mounting position and the companion light 30 is installed in the left mounting position, the first end is closer to the left mounting position than the second end, and the first end is closer to the light-emitting module 21 than the second end, the second reflector 22b can also reflect the light emitted from the first reflector 22a to the center position directly in front of the vehicle head 10.

[0047] When the headlight 20 is applied to a vehicle and is used to project a pattern, the second reflector 22b needs to reflect the pattern to the front of the vehicle head 10. Taking the headlight 20 as an example, when it is installed in the left mounting position, the second reflector 22b needs to reflect the pattern to the right front of the light-emitting module 21. At this time, the pattern reflected by the second reflector 22b will be distorted. For example, a square pattern will present a first diamond pattern after being reflected by the second reflector 22b. In the embodiment provided in the present application, in order to make the pattern presented in front of the middle position of the vehicle head 10 tend to the desired pattern, the desired pattern is pre-processed (inverse phase correction) by software, and the pre-processed pattern is deformed compared to the desired pattern. The light-emitting module 21 transmits the pre-processed pattern to the first reflector 22a, the first reflector 22a reflects the pre-processed pattern to the second reflector 22b, and the second reflector 22b reflects the pre-processed pattern to the front of the middle position of the vehicle head 10. The second reflector 22b distorts the pre-processed pattern into the desired pattern. For example, if the desired pattern is a square, the square is corrected into a second rhombus through software processing, the light-emitting module 21 emits the second rhombus to the first reflector 22a, the first reflector 22a reflects the second rhombus to the second reflector 22b, and the second reflector 22b reflects the second rhombus to the front of the middle position of the front of the vehicle 10, whereupon distortion occurs, causing the pattern presented to the front of the middle position of the front of the vehicle 10 to be distorted into a square.

[0048] In the embodiment provided in the present application, when the desired pattern is pre-processed by software, a point in the pattern is located and other points in the pattern are migrated, so that the pre-processed pattern is deformed as a whole, and the pre-processed pattern is reflected by the first reflector 22a to the second reflector 22b, and the second reflector 22b reflects the pre-processed pattern to the front of the middle position of the vehicle head 10. The pattern presented in front of the middle position of the vehicle head 10 is distorted and converges to the desired pattern, wherein the pattern presented in front of the middle position of the vehicle head 10 converges to the desired pattern means that, in terms of photosensitivity, the pattern presented in front of the middle position of the vehicle head 10 has no obvious deformation compared with the desired pattern.

[0049] The present application also discloses a method for controlling a vehicle lamp 20. The vehicle lamp 20 includes a light-emitting module 21 and a reflector assembly 22. The light-emitting module 21 is used to emit light. The reflector assembly 22 includes a first reflector 22a and a second reflector 22b. The first reflector 22a and the second reflector 22b are spaced apart. The first reflector 22a rotates along the axial direction. Figure 8 , the vehicle light control method includes:

[0050] S101, controlling the first reflector to rotate to a first position, reflecting the light emitted from the light emitting module to the second reflector through the first reflector, and reflecting the light emitted from the first reflector out of the vehicle lamp through the second reflector.

[0051] S102, controlling the first reflector to rotate to a second position, so that the light emitted by the light emitting module is emitted from the vehicle lamp.

[0052] The actuator driving the first reflector 22a to rotate may be a motor.

[0053] The headlight 20 has a welcoming state and an illuminating state, and the two states of the headlight 20 are switchable. When the headlight 20 switches from the welcoming state to the illuminating state, the first reflector 22a is controlled to rotate from the first position to the second position. When the headlight 20 switches from the illuminating state to the welcoming state, the first reflector 22a is controlled to rotate from the second position to the first position.

[0054] Among them, when the headlight 20 is in the welcoming state, the first reflector 22a is in the first position, and the light emitted by the light-emitting module 21 can form a pattern. The first reflector 22a reflects the light emitted from the light-emitting module 21 to the second reflector 22b, and the second reflector 22b reflects the light emitted from the first reflector 22a to the ground in front of the vehicle, presenting a pattern through the ground in front of the vehicle.

[0055] When the vehicle lamp 20 is in the lighting state, the light emitted by the light emitting module 21 directly exits the light emitting module 21 . At this time, the light emitted by the light emitting module 21 can illuminate the vehicle in the driving state.

[0056] In the present application, when the first reflector 22a is controlled to be in the first position, the angle between the first reflector 22a and the optical axis of the light-emitting module 21 is 40° to 50°. Specifically, when the first reflector 22a is in the first position, the angle between the first reflector 22a and the optical axis of the light-emitting module 21 can be 42°, 43°, 44°, 45°, 46°, 47°, etc. The first reflector 22a can reflect the light emitted by the light-emitting module 21 to the second reflector 22b, and the second reflector 22b can reflect the light emitted from the first reflector 22a to the ground in front of the vehicle head 10.

[0057] The angle between the second reflector 22b and the first reflector 22a is 4° to 9°, and the second reflector 22b and the first reflector 22a have an axial angle, and the angle between the normal of the second reflector 22b and the optical axis of the light-emitting module 21 is 44° to 54°. When the headlight 20 is installed in the left or right mounting position of the vehicle head 10, the second reflector 22b can reflect light emitted from the first reflector 22a to the front of the center of the vehicle head 10. When the first reflector 22a is in the first position, the angle between the second reflector 22b and the first reflector 22a can also be 5°, 6°, 7°, 8°, etc., and this application does not impose specific limitations on this.

[0058] When the first reflector 22a is controlled to be in the first position, the angle between the first reflector 22a and the optical axis of the light-emitting module 21 is -7° to -1°. At this time, the first reflector 22a does not participate in the reflection of light, and the second reflector 22b does not participate in the reflection of light. The light emitted by the light-emitting module 21 can be directly emitted from the headlight 20. Among them, when the first reflector 22a is in the first position, the angle between the first reflector 22a and the optical axis of the light-emitting module 21 is -2°, -2.5°, -3°, -3.1°, -4°, etc. This application does not impose any specific restrictions on the angle between the first reflector 22a and the optical axis of the light-emitting module 21.
