[0056] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0057] refer to Figure 1-Figure 4 , an optical device is provided, comprising:

[0058] Signal module 100;

[0059] A first bracket 200 is disposed above the signal module 100 and is used to position and fix the signal module 100;

[0060] An illumination module 300, wherein the light emission direction of the illumination module 300 is opposite to the light emission direction of the signal module 100;

[0061] The second bracket 400 is located below the first bracket 200 and is used to position and fix the lighting module 300;

[0062] A rotating mechanism 500, wherein a rotating shaft 510 of the rotating mechanism 500 connects the first bracket 200 and the second bracket 400, and is used to drive the first bracket 200 and the second bracket 400 to rotate circumferentially around the rotating shaft 510 of the rotating mechanism 500;

[0063] The lighting module 300 and the signal module 100 are arranged in sequence along a circumferential direction perpendicular to the rotating shaft 510, and in the lighting mode, the lighting module 300 is driven by the rotating mechanism 500 to face the visible side; in the signal light mode, the signal module 100 is driven by the rotating mechanism 500 to face the visible side.

[0064] Specifically, the rotating mechanism 500 has the function of rotating around its own rotating shaft 510. When the vehicle is in the signal light function, such as Figure 1 and Figure 2 The signal module 100 faces the visible side (such as the front of the vehicle), and its appearance can be seen by people in front of the vehicle, which is consistent with the functional appearance of traditional signal lights.

[0065] When the lighting function needs to be switched, the rotating mechanism 500 is started, and the lighting module 300 is rotated to the visible side by the circumferential rotation of the rotating mechanism 500. Figure 4 After the lighting module 300 is rotated to face the visible side (such as the front of the vehicle), it can emit light in a normal working mode.

[0066] In actual work, the signal module 100 can be preset in front of the lighting module 300. When the signal module 100 is not lit, the signal module 100 maintains its own transparency and has the same styling effect as the traditional function. At this time, since the lighting module 300 is arranged at the rear of the signal module 100, it cannot be seen from the outside; when the signal module 100 is lit, the signal light function can be realized.

[0067] When lighting is needed, the signal light function is turned off. At this time, the rotary actuator works to rotate the lighting module 300 to the front of the signal module 100 and to the visible area. The lighting module 300 is turned on to emit light to the front of the vehicle, so that the present application realizes the lighting function. At this time, the lighting module 300 is arranged at the rear of the signal module 100 and is blocked and cannot be seen from the outside.

[0068] The present application can realize the arrangement of signal lights and lighting functions simultaneously, the lighting module 300 and the signal module 100 are arranged in sequence along the circumferential direction perpendicular to the rotating shaft 510, that is, the signal module 100 and the lighting module 300 are arranged side by side in a horizontal plane perpendicular to the vertical direction, so as not to occupy too much space in the vertical direction, and realize the integration of various functions in a narrow space with a simple appearance; and when the signal module 100 emits light toward the visible side and the lighting module 300 emits light toward the visible side, they will be in the same light-emitting area with narrow upper and lower dimensions, occupying a small space; when the signal module 100 emits light in the signal light mode and the lighting module 300 emits light in the lighting mode, the appearance of the headlights viewed from the front remains completely consistent; when the lighting and signal functions emit light, they will present the same consistent narrow light type, which can meet the current aesthetic needs.

[0069] The first bracket 200 of this embodiment is disposed at the top, and can be used to cover the signal module 100 from the top to protect the entire optical device.

[0070] It is worth noting that the light emission of the above signal module 100 can be selected as white, yellow, ice blue or RGB according to functional requirements; the light emission of the lighting module 300 can be selected as white according to functional requirements, and the function can be an independent low beam function or a combined function of low beam and high beam.

[0071] refer to Figure 3 In some embodiments, the signal module 100 includes:

[0072] A signal light source module 110, wherein the backlight side of the signal light source module 110 faces upward and is fixed to the first bracket 200, and the light emitting side of the signal light source module 110 faces downward;

[0073] A light display element 120, wherein a light entrance portion 121 and a total reflection portion 123 are sequentially provided on the upper surface of the light display element 120 in a direction gradually away from the rotating mechanism 500, wherein the light entrance portion 121 is opposite to the light exit side of the signal light source module 110 and extends in a horizontal plane, and is used for the signal light emitted by the signal light source module 110 to enter;

[0074] The surface of the light display element 120 on one side close to the rotating mechanism 500 is a dimming surface 122, which is used to receive the signal light and deflect the signal light in a direction away from the rotating mechanism 500 to form a modulated light.

[0075] The lower surface of the light display element 120 is a total reflection surface 124, and the total reflection surface 124 and the total reflection portion 123 are used to alternately reflect the adjustment light to guide the adjustment light to be emitted in a direction away from the rotating mechanism 500;

[0076] The surface of the light display element 120 that is away from the rotating mechanism 500 is a light emitting surface 125 for adjusting the light emission.

[0077] Specifically, the signal light source module 110 of the signal module 100 is hidden and arranged above the light display element 120. After the light enters the light display element 120 from the light entrance part 121 of the light display element 120, it is adjusted by the dimming surface 122 and is alternately totally reflected by the total reflection surface 124 and the total reflection part 123 before finally being emitted from the light output surface 125.

[0078] In this embodiment, after the light is alternately totally reflected by the total reflection surface 124 and the total reflection portion 123 in the light display element 120, the light display element 120 is lit as a whole, realizing the function of a signal light; and because total reflection occurs on the upper and lower surfaces of the light display element 120, no light will leak from the upper and lower surfaces of the light display element 120, and when the light display element 120 emits light, the boundaries of the upper and lower edges are clear and the light effect is good.

[0079] In this embodiment, the signal light source module 110 is hidden and arranged above the light display element 120. On the one hand, the light display element 120 can provide protection for the signal light source module 110. On the other hand, compared with arranging the signal light source module 110 below the light display element 120, the first bracket 200 and the light display element 120 can jointly play a shading role to prevent the light emitted by the signal light source module 110 from directly leaking out and causing light leakage in the entire optical device, thereby ensuring good lighting effect.

[0080] In this embodiment, the total reflection portion 123 and the light incident portion 121 are simultaneously disposed on the upper surface of the optical display element 120 , and no extra design space needs to be reserved for the total reflection portion 123 in the optical device. The structural design is simple and occupies little space.

[0081] refer to Figure 3 In some embodiments, a step portion 126 is formed between the total reflection portion 123 and the light incident portion 121 , and a level of the total reflection portion 123 is lower than a level of the light incident portion 121 .

[0082] Specifically, a step portion 126 formed between the total reflection portion 123 and the light entrance portion 121 is used to form a clear optical boundary between the total reflection portion 123 and the light entrance portion 121, in order to prevent the light emitted from the light-emitting side of the signal light source module 110 from directly entering the light display element 120 from the surface of the total reflection portion 123 and then penetrating downwardly through the light display element 120 to emit excess stray light, and to make the boundary of the light display element 120 blurred and the light effect worse. After the step portion 126 is provided between the total reflection portion 123 and the light entrance portion 121, the optical boundary formed can separate the total reflection portion 123 and the light entrance portion 121, so that the light emitted by the signal light source module 110 will not enter the surface of the total reflection portion 123, thereby eliminating the excess stray light that enters the light display element 120 from the surface of the total reflection portion 123 and then penetrating downwardly through the light display element 120 to emit excess stray light, and the boundaries of the upper and lower edges are clearer, thereby improving the light effect.

[0083] refer to Figure 3In some embodiments, the first bracket 200 includes a first covering portion 210, a step portion 220 and a third covering portion 230 in sequence along a direction gradually away from the rotating mechanism 500, the first covering portion 210 and the third covering portion 230 respectively cover the light incident portion 121 and the total reflection portion 123, and a surface of the step portion 220 facing the step portion 126 matches the surface shape of the step portion 126.

[0084] Specifically, the step portion 220 of the first bracket 200 corresponds to covering the surface of the step portion 126, and can cover the step portion 126 to prevent the light emitted by the signal light source module 110 from leaking out from the surface of the step portion 126 and entering the light display element 120 through the surface of the total reflection portion 123, thereby further reducing the light that enters from the surface of the total reflection portion 123 and passes through the light display element 120 up and down, eliminating stray light and improving light efficiency.

[0085] If the first bracket 200 and the second bracket 400 are respectively mounted on the rotating shaft 510 and directly connected to the rotating mechanism 500, since two separate assembly gaps of different sizes are formed at the connection parts between the first bracket 200 and the rotating mechanism 500, and between the second bracket 400 and the rotating mechanism 500, when the rotating shaft 510 rotates, the first bracket 200 and the second bracket 400 will respectively rotate with different degrees of delay, resulting in a deviation in the rotation angles of the signal module 100 and the lighting module 300 and being unable to maintain synchronization. When the function is switched, one of the signal module 100 and the lighting module 300 cannot rotate to the preset position, and then the following will occur: in the signal light mode, either when the lighting module 300 moves to the preset position, the signal module 100 has an angle deviation and cannot face forward, or when the signal module 100 moves toward the front, the lighting module 300 cannot reach directly behind the signal module 100, so that it can be seen from the outside and affects the appearance. For this reason, refer to Figure 3 In some embodiments, the signal light source module 110 includes a signal circuit board 111 and a light source disposed on the lower surface of the signal circuit board 111, the signal circuit board 111 is fixed to the lower surface of the first bracket 200, and the rotating shaft 510 of the rotating mechanism 500 passes through the signal circuit board 111 and the first bracket 200;

[0086] The second bracket 400 is configured to be fixedly connected to the lower surface of the signal circuit board 111 .

[0087] Specifically, in this embodiment, the rotating mechanism 500 is directly connected to the first bracket 200, and the second bracket 400 is fixedly connected to the first bracket 200 through the signal circuit board 111, that is, the second bracket 400 and the first bracket 200 form a solid whole. Compared with the solution in which the first bracket 200, the second bracket 400 and the rotating mechanism 500 are connected separately, in this embodiment, when the rotating mechanism 500 rotates, the second bracket 400 and the first bracket 200 rotate at exactly the same angle value, and the rotation of the signal module 100 and the lighting module 300 always remains completely synchronized. When the function is switched, both the signal module 100 and the lighting module 300 can accurately reach the preset position at the same time, and the product can achieve the expected effect. For example, after the rotating shaft 510 rotates in the signal light mode, when the signal module 100 is just facing forward, the lighting module 300 also moves to the back of the signal module 100 and will not be seen from the outside, thereby eliminating the angle deviation and fully achieving the expected light effect.

[0088] refer to Figure 3 In some embodiments, preferably, the second bracket 400 is fixedly connected to the lower surface of the signal circuit board 111 through a connecting pin 401. Since the design space of the optical device itself is narrow and the installation space is limited, the connecting pin 401 is designed to directly penetrate from above to connect the second bracket 400 and the signal circuit board 111, and the required operating space is small; the connecting pin 401 directly penetrates the second bracket 400 and the signal circuit board 111 to achieve a firm connection between the two.

[0089] It is worth noting that, in addition to the implementation methods of the above embodiments, the signal module 100 can also use module structures such as internal and external light distribution mirror structures, reflective mirrors, etc. that can realize signal functions, which is not limited here.

[0090] refer to Figure 3 In some embodiments, the lighting module 300 includes:

[0091] The lighting source module 310 is fixed to the second bracket 400;

[0092] A reflector 320, fixed to the second bracket 400 and disposed on the light-emitting side of the illumination light source module 310, for receiving and reflecting the illumination light emitted by the illumination light source module 310 to form reflected light;

[0093] The lens module 330 is disposed on the reflected light emitting side of the reflector 320 , and is used to allow the reflected light to pass through and emit illumination light along the normal direction of the light emitting surface of the lens.

[0094] Specifically, the light emitted by the lighting source module 310 of this embodiment is reflected by the reflector 320 and then emitted directly along the normal direction of the light-emitting surface of the lens module 330. There are no obstacles in front of the emitted light and it is not affected by the material and structure. The light can be emitted directly forward and seen, thus ensuring the normal use of the lighting function.

[0095] refer to Figure 5 In some embodiments, the lighting source modules 310, reflectors 320 and lens modules 330 that cooperate with each other are provided in plurality, and are arranged in sequence in the width direction of the optical device and staggered in sequence in the front-to-back direction. Multiple groups of lighting source modules 310, reflectors 320 and lens modules 330 can emit lighting beams respectively, and can be staggered in sequence in the front-to-back direction along the actual shape curvature of the vehicle body, so as to better match the actual shape of the vehicle body and be more practical.

[0096] refer to Figure 1 and Figure 5 In some embodiments, the angle between the light emitting directions of the lighting module 300 and the signal module 100 is 180 degrees.

[0097] Specifically, the light emitting directions of the lighting module 300 and the signal module 100 are completely opposite. When the signal module 100 is facing straight ahead, the lighting module 300 is facing straight behind. At this time, the lighting module 300 is completely blocked by the signal module 100 and is not visible. When the functional mode needs to be switched, the rotating mechanism 500 only needs to rotate a fixed 180 degrees each time. There is no need to set a precise rotation angle. The operation is efficient and there will be no angle deviation.

[0098] refer to Figure 1-Figure 3 In some embodiments, the signal module 100 and the lighting module 300 are arranged at the same height; the light emitting surface 125 of the signal module 100 and the light emitting surface 125 of the lighting module 300 have the same height dimension in the vertical direction and the same extended width dimension in the horizontal plane.

[0099] In this embodiment, the light emitting surface 125 of the signal module 100 and the light emitting surface 125 of the lighting module 300 have the same height dimension, and the extended width dimension in the horizontal plane is consistent. When this setting is adopted, when the signal module 100 or the lighting module 300 is facing the visible side, it can be exactly matched and embedded in the decorative ring of the vehicle headlight, and completely share the same narrow light emitting area in the upper and lower dimensions, occupying the minimum space; and when the signal module 100 is illuminated in the signal light mode and the lighting module 300 is illuminated in the lighting mode, the appearance effect of looking at the headlight from the front remains completely consistent; when emitting light in the two modes, the same consistent narrow light type is presented, which can meet the current aesthetic needs.

[0100] refer to Figure 3In some embodiments, the rotating mechanism 500 includes a rotating stepping motor, and a rotating shaft 510 of the rotating stepping motor passes through and is connected to the first bracket 200 .

[0101] In this embodiment, the second bracket 400 is fixedly connected to the first bracket 200 through the signal circuit board 111, that is, the second bracket 400 and the first bracket 200 form a solid whole, and the rotary stepper motor is only arranged in the first bracket 200. Compared with the solution that the rotary stepper motor is simultaneously arranged to connect the first bracket 200 and the second bracket 400, the rotary stepper motor will not form two assembly gaps of different sizes with the second bracket 400 and the first bracket 200 respectively. When the rotary stepper motor rotates, the second bracket 400 and the first bracket 200 can both rotate at the same angle at the same time, and the rotation of the signal module 100 and the lighting module 300 always remains completely synchronized. When the function is switched, both the signal module 100 and the lighting module 300 can accurately reach the preset position at the same time, and the product can achieve the expected effect. For example, after the shaft 510 rotates in the signal light mode, when the signal module 100 is facing forward, the lighting module 300 also moves to the rear of the signal module 100 and cannot be seen from the outside, thereby eliminating the angle deviation and achieving the expected light effect.

[0102] In some embodiments, the vertical dimension of the lighting module 300 is not greater than 30 mm. It has been verified that if the vertical dimension of the lighting module 300 is greater than 30 mm, its volume and space occupied are large, and it is difficult to rotate.

[0103] In some embodiments, a dimming mechanism is also included, and the dimming mechanism and the rotating mechanism 500 are both installed on the same support; the dimming mechanism is independently arranged from the rotating mechanism 500 and is located on the light output side of the optical device, and is used to dim the luminous signal module 100 or the lighting module 300.

[0104] Specifically, the dimming mechanism is independently provided from the rotating mechanism 500, and the rotation of the rotating mechanism 500 will not drive the dimming mechanism to move. After the rotating actuator is operated to switch the lighting module 300 or the signal module 100 toward the visible side, the dimming mechanism can dim the lighting module 300 or the signal module 100 that is facing the visible side and emitting light without being affected by the rotation of the rotating mechanism 500.

[0105] The present application also provides a headlight, in which the optical device is provided. When the signal module 100 of the optical device faces the visible side in front of the headlight, and when the lighting module 300 of the optical device faces the visible side in front of the headlight, they are respectively matched and embedded in the decorative ring of the headlight, and are in the same light emitting area.

[0106] After the above-mentioned optical device is installed in the headlight, the arrangement of the signal light and the lighting functions can be realized simultaneously. The lighting module 300 and the signal module 100 are arranged in sequence along the circumferential direction perpendicular to the rotating shaft 510, that is, the signal module 100 and the lighting module 300 are arranged side by side in a horizontal plane perpendicular to the vertical direction, so as not to occupy too much space in the vertical direction, so as to realize the integration of various functions in the narrow inner cavity space of the headlight with a simple appearance; and when the signal module 100 emits light toward the visible side and the lighting module 300 emits light toward the visible side, they will be in the same light-emitting area with narrow upper and lower dimensions, occupying a small space; when the signal module 100 emits light in the signal light mode and the lighting module 300 emits light in the lighting mode, the appearance of the headlight viewed from the front remains completely consistent; when the lighting and signal functions emit light, they will present the same consistent narrow light type, which can meet the current aesthetic needs.

[0107] refer to Figure 5 In some embodiments, when the lighting module 300 and the signal module 100 are respectively facing the visible side, the light emitting surfaces of the lighting module 300 and the signal module 100 are respectively matched with the shape of the vehicle light display surface. For example, when the light display element 120 of the signal module 100 is facing the visible side, the light emitting surface 125 is consistent with the extension direction of the vehicle light display surface; or, when the lighting module 300 is facing the visible side, the lens modules 330 are sequentially staggered in the front-to-back direction, so as to better match the actual shape of the vehicle light display surface, and improve practicality and aesthetics.

[0108] The present application also discloses a vehicle, comprising the vehicle light in any of the aforementioned embodiments.

[0109] The above-mentioned means of transportation may be a car, a train, a high-speed train or other means of transportation that requires headlights.
