[0045] In order to facilitate understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0046] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0047] It is understood that when an element is considered to be "connected" to another element, it can be directly connected to the other element, or connected to the other element through an intermediate element. The "connection" in the following embodiments should be understood as "electrical connection", "communication connection", etc. if the connected circuits, modules, units, etc. have electrical signals or data transmission between each other.

[0048] At present, the signal lights inside the car headlights are fixedly installed on both sides of the car. This installation method makes the display mode of the signal lights inside the headlights single, and only one of the ordinary light guides, thick-walled parts or reflector lighting forms can be selected. It is difficult to meet the user's demand for multi-mode switching of the lighting shape of smart driving lights.

[0049] Based on this, the embodiments of the present application propose a vehicle lamp and a vehicle to solve the problem of the single display effect of traditional vehicle signal lights.

[0050] See also Figures 1 to 3 , Figure 1 A schematic diagram of the structure of a vehicle lamp provided in an embodiment of the present application is shown. Figure 2 Shows Figure 1 The schematic cross-sectional view of the headlight along line aa in the figure. Figure 3 Shows Figure 1A vehicle lamp 100 provided in an embodiment of the present application comprises a lamp holder 10, a lamp 20 disposed on the lamp holder 10, and an adjustment mechanism 30, wherein the lamp 20 comprises a lamp housing 21 and a light-emitting component 22 disposed in the lamp housing 21, wherein the lamp housing 21 has a plurality of light-transmitting surfaces 21a, and at least some of the light-transmitting surfaces 21a have different light-transmitting shapes; and the adjustment mechanism 30 is connected to the lamp housing 21, and is used to adjust the lamp housing 21 so that the target light-transmitting surface 21a of the lamp housing 21 faces the light-emitting direction of the vehicle lamp 100.

[0051] Specifically, the vehicle lamp 100 in this embodiment can be used as a welcome lamp, position lamp, brake lamp or reverse lamp of a vehicle, etc., and can be set specifically according to actual conditions. The lamp holder 10 is used to be installed on the vehicle's vehicle lamp bracket. The lamp housing 21 has a plurality of light-transmitting surfaces 21a, and at least some of the light-transmitting surfaces 21a have different sizes or light-transmitting shapes to present different display effects. The adjustment mechanism 30 is connected to the lamp housing 21, and the adjustment mechanism 30 can adjust the display state of the lamp housing 21 so that the target light-transmitting surface 21a faces the light emitting direction of the vehicle lamp 100. In a specific embodiment, Figure 1 , Figure 4 and Figure 5 As shown, the surface of the lamp housing 21 may be provided with three different light-transmitting surfaces 21a, and the adjustment mechanism 30 may be controlled to adjust the position of the lamp housing 21 according to the central control system or the vehicle screen of the vehicle, so that the target light-transmitting surface 21a faces the light-emitting direction of the vehicle lamp 100. In other embodiments, the surface of the lamp housing 21 may be provided with two, four or five different light-transmitting surfaces 21a, which may be specifically set according to actual needs, and this embodiment is not limited here.

[0052] In this embodiment, a lamp 20 and an adjustment mechanism 30 are arranged on the lamp holder 10. The lamp 20 includes a lamp housing 21 and a light-emitting component 22 arranged in the lamp housing 21. The lamp housing 21 has a plurality of light-transmitting surfaces 21a, and at least some of the light-transmitting surfaces 21a have different light-transmitting shapes. The adjustment mechanism 30 is connected to the lamp housing 21. The lamp housing 21 is adjusted by the adjustment mechanism 30 so that the target light-transmitting surface 21a of the lamp housing 21 faces the light emitting direction of the vehicle lamp 100 to present a specific display effect, thereby satisfying a variety of display effects and improving the driving experience of the car.

[0053] In some embodiments, when the light emitting component 22 adopts direct light emitting mode, the light emitting component 22 includes a light source; when the light emitting component 22 adopts indirect light emitting mode, the light emitting component 22 includes a light source and an optical element.

[0054] Specifically, in this embodiment, the light source can be an LED, which can emit white light or colored light, and the light source is electrically connected to a circuit board. The optical element can be any one of a light guide, a concentrator, a thick-walled member, or a reflector, wherein the light guide is used to guide the light emitted by the light source; the concentrator is used to concentrate the light and improve the utilization rate of light energy; the thick-walled member is used to achieve effective transmission and diffusion of light; and the reflector is used to adjust and control the direction of light. In this way, when the light-emitting component 22 adopts a direct light-emitting mode, the light-emitting component 22 adopts LED direct emission. When the light-emitting component 22 adopts an indirect light-emitting mode, the LED indirect emission is achieved through optical elements to achieve a better lighting effect.

[0055] In some embodiments, at least a portion of the light-transmitting surfaces 21 a share the light-emitting components 22. Alternatively, each light-transmitting surface 21 a corresponds to each light-emitting component 22 one by one.

[0056] Specifically, Figure 6 and Figure 7 As shown, among the multiple light-transmitting surfaces 21a, all the light-transmitting surfaces 21a share a set of light-emitting components 22, or one or several of the light-transmitting surfaces 21a share a set of light-emitting components 22. During the process of adjusting the position of the lamp housing 21 by the adjustment mechanism 30, the light-emitting components 22 can illuminate each light-transmitting surface 21a, and through the adjustment mechanism 30, one of the target light-transmitting surfaces 21a is directed toward the light-emitting direction of the vehicle lamp 100 to present a specific display effect. In this way, at least some of the light-transmitting surfaces 21a share a set of light-emitting components 22, so as to facilitate the control of the light emission of the light-emitting components 22, and also facilitate the arrangement of the light-emitting components 22 in the lamp housing 21.

[0057] Alternatively, each light-transmitting surface 21a is provided with a set of light-emitting components 22. When the adjustment mechanism 30 adjusts the position of the lamp housing 21, the light-emitting components 22 are adjusted together with the corresponding light-transmitting surfaces 21a so that the lighting direction of the light-emitting components 22 corresponding to the target light-transmitting surface 21a is at least toward the light-emitting direction of the vehicle lamp 100. In this way, each light-transmitting surface 21a has an independent light-emitting system, so that each light-transmitting surface 21a can achieve better lighting effect or specific display effect.

[0058] Continue reading Figure 1 and Figure 2 , and combined with Figures 7 to 9 In some embodiments, the adjustment mechanism 30 includes a rotating shaft 31 and a driving member 32. The rotating shaft 31 passes through two opposite ends of the lamp housing 21. The opposite ends of the rotating shaft 31 are rotatably disposed on the lamp holder 10. The driving member 32 is disposed on the lamp holder 10 and is rotatably connected to the rotating shaft 31. The driving member 32 drives the rotating shaft 31 to rotate, so that the lamp housing 21 rotates to display the target light-transmitting surface 21a.

[0059] Specifically, the shaft 31 passes through opposite ends of the lamp housing 21, a boss 31a is provided on the shaft 31, and a groove 21b is provided inside the lamp housing 21. The boss 31a of the shaft 31 and the groove 21b inside the lamp housing 21 are engaged so that the shaft 31 can drive the lamp housing 21 to rotate. It should be noted that a space is left between the bottom of the lamp housing 21 and the lamp holder 10 so that the lamp housing 21 can rotate smoothly.

[0060] In this embodiment, if Figure 8 and Fig. 9 As shown, the lamp housing 21 includes an upper decorative ring 211 and a lower decorative ring 212, both of which include a light-transmitting structure and a non-light-transmitting structure, and are injection molded using a two-color material. The light-transmitting structure is made of milky white plastic, and the non-light-transmitting structure is made of black plastic. A portion of the light emitted by the light-emitting component 22 can be transmitted from the surface of the light-transmitting structure (i.e., the light-transmitting surface 21a), and the other portion of the light is absorbed by the surface of the non-light-transmitting structure. The non-light-transmitting structure of the upper decorative ring 211 and the non-light-transmitting structure of the lower decorative ring 212 are connected together by setting a welding strip L and laser welding. In this embodiment, a boss 31a is provided on the rotating shaft 31, and a groove 21b is provided on the inner wall of the light-transmitting structure / non-light-transmitting structure of the upper decorative ring 211. The groove 21b of the light-transmitting structure / non-light-transmitting structure of the upper decorative ring 211 and the boss 31a of the rotating shaft 31 are engaged, so that the lamp housing 21 can rotate with the rotating shaft 31.

[0061] In a specific embodiment, a light-transmitting structure is embedded in the non-light-transmitting structure of the upper decorative ring 211 to display a light-transmitting surface 21a, and two light-transmitting structures are embedded in the non-light-transmitting structure of the lower decorative ring 212 along its circumference to display two light-transmitting surfaces 21a, respectively, so that the three light-transmitting surfaces 21a are located at different rotational orientations of the lamp housing 21. Alternatively, a light-transmitting structure is embedded in the non-light-transmitting structure of the lower decorative ring 212 to display a light-transmitting surface 21a, and two light-transmitting structures are embedded in the non-light-transmitting structure of the upper decorative ring 211 along its circumference to display two light-transmitting surfaces 21a, respectively, so that the three light-transmitting surfaces 21a are located at different rotational orientations of the lamp housing 21.

[0062] In this way, the shaft 31 passes through the lamp housing 21, and the opposite ends of the shaft 31 are rotatably disposed on the lamp holder 10, and the shaft 31 is driven by the driving member 32 to drive the lamp housing 21 to rotate the angles of each light-transmitting surface 21a, so that the target light-transmitting surface 21a faces the light emitting direction of the vehicle lamp 100, thereby presenting a specific display effect.

[0063] In some embodiments, continue to refer to Figure 7 The light emitting component 22 is disposed in the lamp housing 21 along the axis direction of the rotating shaft 31 . Alternatively, the light emitting component 22 is disposed in the lamp housing 21 around the axis direction of the rotating shaft 31 .

[0064] Specifically, the light emitting assembly 22 can be arranged in the lamp housing 21 along the axis direction of the rotating shaft 31 by providing a bearing and a fixing structure, so that each light-transmitting surface 21a shares the light emitting assembly 22. Alternatively, multiple light emitting assemblies 22 can be arranged in the lamp housing 21 around the axis direction of the rotating shaft 31 by providing a bracket, so that each light-transmitting surface 21a has an independent light emitting assembly 22. In this way, the arrangement of the light emitting assembly 22 can be flexibly arranged according to the size of the lamp housing 21 and the light control method, so as to have more implementation methods.

[0065] Continue reading Figure 2 , Figure 8 and Fig. 9 , and combined with Fig.10 and Fig.11 In some embodiments, the light emitting component 22 includes a light source and a light guide, one end of the light emitting component 22 passes through the rotating shaft 31 along the first direction F1 and is connected to the lamp holder 10, and the other end of the light emitting component 22 is sleeved with a first bearing G1, and the first bearing G1 is disposed in the lamp housing 21. The first direction F1 is parallel to the axial direction of the rotating shaft 31.

[0066] Specifically, in the present embodiment, the light-emitting component 22 includes a light source and a light guide, and the light-emitting component 22 is configured as a rod-shaped structure. The rotating shaft 31 includes a middle section 311 and two tail sections 312, the middle section 311 is connected between the two tail sections 312, the middle section 311 is configured as a longitudinally distributed rectangular frame, and the two tail sections 312 are configured as semicircular tubes. The rotating shaft 31 passes through the end of the lamp housing 21 along the first direction F1 through the tail sections 312. One of the tail sections 312 is connected to a real shaft section 313, and the real shaft section 313 is rotatably connected to the driving member 32. The light-emitting component 22 is located on the central axis of the rotating shaft 31, one end of the light-emitting component 22 passes through one of the tail sections 312 of the rotating shaft 31 along the first direction F1, and at the same time passes through one end of the lamp housing 21, and is connected to the fixing plate 10a on the lamp holder 10, and the other end of the light-emitting component 22 is fixedly sleeved with a first bearing G1, and the first bearing G1 is limited to the end of the lamp housing 21 along the first direction F1, such as Figure 2 As shown. The first bearing G1 is configured as a ball bearing. In this embodiment, a limiter R is provided on the inner wall of the end of the lamp housing 21. The limiter R is constructed as a semicircular tube. The limiter R and the other tail section 312 of the rotating shaft 31 enclose a limit space, and the first bearing G1 is placed in the limit space. In this way, during the rotation of the rotating shaft 31 and the lamp housing 21, the outer ring of the first bearing G1 rotates with the rotating shaft 31 and the lamp housing 21, and the inner ring of the first bearing G1 is fixed, so that the light-emitting component 22 remains relatively still. When the lamp housing 21 rotates to display any light-transmitting surface 21a, the light-emitting component 22 can be used to light up and present a display effect.

[0067] For further information, see Figure 8 and Fig.11The light emitting component 22 is provided with a reflective plate 23 along the first direction F1, and the reflective plate 23 is used to reflect part of the emitted light of the light emitting component 22.

[0068] Specifically, the light emitting assembly 22 is a rod-shaped structure, the cross-section of the reflector 23 is arc-shaped, and the reflector 23 is made of elastic material. A plurality of clamps 231 are provided in the reflector 23, and the light emitting assembly 22 is clamped in the reflector 23 through the plurality of clamps 231. In this way, part of the emitted light of the light emitting assembly 22 can be reflected by the reflector 23, thereby guiding the transmission direction of the emitted light, so that the lamp 20 can achieve a better lighting effect.

[0069] Continue reading Figure 8 and Fig.11 In some embodiments, a permanent magnet 40 is provided at one end of the rotating shaft 31 along its axial direction, and a linear Hall sensor 50 is provided at intervals on the side of the permanent magnet 40 away from the rotating shaft 31. The linear Hall sensor 50 is connected to the lamp holder 10 and electrically connected to the control board M1 to correct the rotation angle of the lamp housing 21.

[0070] Specifically, the permanent magnet 40 is configured as a pancake-shaped magnetic steel, and a magnetic steel sleeve 41 is sleeved on one end of the rotating shaft 31 along its axial direction. The magnetic steel sleeve 41 and the rotating shaft 31 are connected by a spline, and a magnetic steel (that is, the permanent magnet 40) is clamped in the magnetic steel sleeve 41. When the rotating shaft 31 rotates, the magnetic steel is driven to rotate by the magnetic steel sleeve 41. Further, a linear Hall sensor 50 is arranged at intervals on the side of the permanent magnet 40 away from the rotating shaft 31 along the first direction F1, and the center of the linear Hall sensor 50 is coaxial with the center of the permanent magnet 40. In this embodiment, the linear Hall sensor 50 is arranged on the control board M1, and the control board M1 is fixed to the lamp holder 10 by screwing, so that the linear Hall sensor 50 is indirectly fixed to the lamp holder 10, and the linear Hall sensor 50 is electrically connected to the control board M1, and the rotation angle of the lamp housing 21 is detected and corrected by the linear Hall sensor 50.

[0071] When the shaft 31 rotates, the permanent magnet 40 is driven to rotate by the magnetic steel sleeve 41. The relative position between the permanent magnet 40 and the linear Hall sensor 50 is different, so the linear Hall sensor 50 outputs PWM signals with different duty cycles. The control board M1 determines the position of the permanent magnet 40 through the PWM signal to determine the real-time rotation angle of the shaft 31. According to the preset rotation angle set by the control board M1 for the shaft 31, the real-time rotation angle of the shaft 31 is corrected to rotate to the preset rotation angle, so that the lamp housing 21 displays the target light-transmitting surface 21a. In addition, when the linear Hall sensor 50 detects that the shaft 31 has not rotated to the preset rotation angle, an alarm signal can be issued through the control board M1 to prompt the user to re-operate or conduct an inspection. In this way, the rotation accuracy of the car lamp 100 can be improved and the stability of the use of the car lamp 100 can be ensured.

[0072] Continue reading Figure 1 , Figure 2 Hehe Figure 8 In some embodiments, the driving member 32 includes a stepper motor 321 and a worm 322 and a turbine 323 meshing with each other. The stepper motor 321 is disposed on the lamp holder 10 and the output shaft of the stepper motor 321 is connected to the worm 322. The turbine 323 is sleeved on the rotating shaft 31 and is disposed close to the lamp housing 21.

[0073] Specifically, the stepper motor 321 can be fixed to the lamp holder 10 by screwing, the output shaft of the stepper motor 321 and the worm 322 are connected by splines, the worm 322 and the turbine 323 are meshed with each other, and the turbine 323 is sleeved on the rotating shaft 31 and arranged close to the lamp housing 21. In this embodiment, the stepper motor 321 drives the turbine 323 and the worm 322 with a reduction ratio of 10:1, that is, the stepper motor 321 rotates one circle, and the turbine 323 and the worm 322 rotate ten circles in combination. In this way, when the stepper motor 321 drives the worm 322 to rotate, the rotation of the turbine 323 drives the rotating shaft 31 to rotate, so that the target light-transmitting surface 21a of the lamp housing 21 rotates to the light-emitting direction of the vehicle lamp 100.

[0074] In some embodiments, an annular groove (not shown) is provided on the outer periphery of the rotating shaft 31, and the turbine 323 is sleeved on the annular groove. Further, an E-type retaining spring K1 may be provided between the side wall of the annular groove and the turbine 323, such as Figure 8 As shown, the turbine 323 is limited in the first direction F1.

[0075] Continue reading Figure 2 and Figure 8 In some embodiments, the rotating shaft 31 is sleeved with a second bearing G2 at both ends along the axial direction thereof, the second bearing G2 is disposed on the lamp holder 10 , and a stop structure is disposed on both sides of the second bearing G2 along the first direction F1 .

[0076] Specifically, in the present embodiment, both ends of the lamp holder 10 along the first direction F1 are provided with mounting seats 10b, each second bearing G2 is installed on the mounting groove 10c of a corresponding mounting seat 10b, and the corresponding second bearing G2 is covered by a bearing cover plate H, and each bearing cover plate H is fixed to the corresponding mounting seat 10b by screw connection. In the present embodiment, both second bearings G2 are ball bearings, and the size or shape of the two second bearings G2 can be adaptively adjusted according to actual conditions. In the present embodiment, in the first direction F1, the groove wall of each mounting groove 10c forms a stop structure for the corresponding second bearing G2 along one side of the first direction F1, and an E-type retaining spring K1 or a spring K2 can be provided on the rotating shaft 31 to form a stop structure for the other side of the second bearing G2. In this way, by providing stop structures on both sides of the second bearing G2 along the first direction F1, the second bearing G2 is limited to move along the first direction F1, thereby playing a limiting role.

[0077] In some embodiments, at least part of the light-transmitting surfaces 21a are used to display different signals. Specifically, among the multiple light-transmitting surfaces 21a, part or all of the light-transmitting surfaces 21a are used to display different signals. For example, among the three light-transmitting surfaces 21a, one light-transmitting surface 21a is used to display the reversing signal of the car, another light-transmitting surface 21a is used to display the position signal of the car, and the remaining light-transmitting surface 21a is used to display the welcome signal of the car. Alternatively, among the three light-transmitting surfaces 21a, one light-transmitting surface 21a is used to display the start signal of the car, and the other two light-transmitting surfaces 21a are used to display the welcome signal of the car, and different welcome effects are displayed. The display purpose of each light-transmitting surface 21a can be set according to actual needs.

[0078] Based on the same inventive concept, an embodiment of the present application further provides a vehicle, comprising a vehicle lamp 100 as in any of the previous embodiments.

[0079] In summary, the vehicle lamp 100 of this embodiment is provided with a lamp 20 and an adjustment mechanism 30 on a lamp holder 10.

The lamp housing 21 has a plurality of light-transmitting surfaces 21a, and at least some of the light-transmitting surfaces 21a have different light-transmitting shapes. The adjustment mechanism 30 is connected to the lamp housing 21. The lamp housing 21 is adjusted by the adjustment mechanism 30 so that the target light-transmitting surface 21a of the lamp housing 21 faces the light-emitting direction of the vehicle lamp 100 to present a specific display effect, thereby satisfying a variety of display effects and improving the driving experience of the car. In addition, each light-transmitting surface 21a can share a set of light-emitting components 22, or each light-transmitting surface 21a can have a set of light-emitting components 22 exclusively. The light-emitting components 22 can adopt a direct light-emitting mode or an indirect light-emitting mode, and the structure of the light-emitting components 22 can be flexibly set. The adjustment mechanism 30 includes a rotating shaft 31 and a driving member 32. The rotating shaft 31 passes through two opposite ends of the lamp housing 21. The two opposite ends of the rotating shaft 31 are rotatably arranged on the lamp holder 10. The driving member 32 is arranged on the lamp holder 10 and is rotatably connected to the rotating shaft 31. The driving member 32 drives the rotating shaft 31 to rotate, so that the lamp housing 21 rotates to display the target light-transmitting surface 21a. By arranging a permanent magnet 40 and a linear Hall sensor 50 at the end of the rotating shaft 31, the linear Hall sensor 50 is electrically connected to the control board M1. During the rotation of the rotating shaft 31, the linear Hall sensor 50 outputs PWM signals with different duty cycles, so that the control board M1 can judge and correct the real-time rotation angle of the rotating shaft 31, thereby improving the rotation accuracy of the vehicle lamp 100 and ensuring the stability of the vehicle lamp 100.
