Description

Technical Field

[0001] The present invention relates to a vehicle lighting system, in particular to a vehicle lighting device. In addition, the present invention also relates to a vehicle headlight and a vehicle. Background Art

[0002] With the continuous development of vehicle lighting technology, the technical development of lighting devices has become diversified. One of the development trends is to set multiple lighting modules arranged in a certain way in the vehicle lamp, which makes the shape of the lamp better. The lighting areas formed by these lighting modules are superimposed on each other to form a high beam light shape and / or a low beam light shape.

[0003] In order to obtain an ideal lighting light shape, during the manufacturing process of the vehicle lighting device, it is necessary to adjust the position of each lighting module and the position of the assembly composed of multiple lighting modules so that the lighting light shape reaches the ideal state and position, which is usually called dimming operation. Dimming is usually carried out in two steps. The first step is to dim each lighting module, and by swinging the lighting module up and down, left and right, the relative position between the lighting areas of multiple lighting modules is determined. The second step is to adjust the position of the entire assembly, that is, the entire lighting light shape with the determined relative position relative to the V axis and the H axis, and adjust the light shape to the theoretical position by swinging the assembly up and down, left and right.

[0004] In the actual dimming process, the up and down and left and right swing angles of each lighting module and assembly are small. For a traditional vehicle lighting device composed of a single lighting module, the swing space required for dimming is very small. However, for a vehicle lighting device composed of multiple lighting modules, such as Figure 1 In the vehicle lighting device shown, nine lighting modules 20A-20I are arranged in a row from top to bottom on the bracket 10. When the bracket 10 rotates around the rotation axis 43 by a very small angle, such as 5°, the other end of the bracket 10 swings greatly, which requires a large space inside the lamp to achieve dimming of the assembly, resulting in a waste of space inside the lamp and an excessively large volume of the lamp.

[0005] Recently, a dimming technology for independently rotating multiple lighting modules has also emerged, but it sets the multiple lighting modules separately in a rotatable frame. The setting of the frame and the space required for its rotation make the setting spacing between adjacent lighting modules larger, and cannot effectively solve the problems of wasted internal space of the car lamp and excessive volume of the car lamp. Summary of the invention

[0006] The technical problem to be solved by the present invention is to provide a vehicle lighting device which can complete the dimming process of the lighting device by occupying only a small space.

[0007] A further technical problem to be solved by the present invention is to provide a vehicle headlight, which has good internal space utilization and small volume.

[0008] In addition, the technical problem to be solved by the present invention is to provide a vehicle whose headlights are small in size and easy to adjust.

[0009] In order to solve the above technical problems, the present invention provides a vehicle lighting device on one hand, including a bracket, a plurality of rotating arms and a plurality of lighting modules, each of the rotating arms including a driving column and a rotating shaft; the plurality of lighting modules are respectively mounted on the corresponding rotating arms, and each of the rotating shafts can be rotatably mounted on the bracket so that each of the rotating arms can independently rotate around the rotating shaft under the drive of the driving column; the rotating shafts are horizontally arranged and parallel to each other.

[0010] Further preferably, the vehicle lighting device of the present invention also includes a driving unit, the driving unit includes an upper guide column, a lower guide column and a plurality of waist-shaped holes; the axes of the upper guide column and the lower guide column are parallel to each other, the driving unit is installed on the bracket through the upper guide column and the lower guide column, and is suitable for up and down movement relative to the bracket; the plurality of driving columns can be slidably installed in the plurality of waist-shaped holes respectively. Through this preferred technical solution, the plurality of driving columns are respectively installed in the plurality of waist-shaped holes, and when the driving unit moves up and down, the plurality of driving columns can be driven to rotate up and down synchronously, so as to drive the rotating arm and the lighting module installed thereon to rotate synchronously. The setting of the waist-shaped holes can adapt to the relative sliding caused by the up and down movement of the driving unit and the rotational movement of the driving column.

[0011] Furthermore, the vehicle lighting device of the present invention further comprises a driving mechanism and a connecting rod, one end of the connecting rod is connected to the driving mechanism, and the other end is connected to the driving part; the driving mechanism is suitable for driving the connecting rod to move up and down, and driving the driving part to move up and down through the connecting rod. In this preferred technical solution, the driving part and the driving mechanism are connected together through the connecting rod, which can not only transmit the up and down movement generated by the driving mechanism to the driving part, but also facilitate the setting of the relative position between the driving mechanism and the driving part, making the structure of the vehicle lighting device of the present invention more compact.

[0012] Furthermore, the driving mechanism includes an electric driving mechanism and / or a manual driving mechanism, and both the electric driving mechanism and the manual driving mechanism are suitable for driving the connecting end of the connecting rod and the driving mechanism to move up and down. Through this preferred technical solution, the electric driving mechanism can drive the driving part to move up and down by electronic control, so as to conveniently and synchronously adjust the position of the lighting area of ​​each lighting module in the vertical direction in real time, that is, to adjust the overall position of the light shape formed by the combination of each lighting area in the vertical direction; the manual driving mechanism can manually adjust the position of the lighting area of ​​the lighting module when the electric driving mechanism is turned off or fails.

[0013] Preferably, each lighting module is respectively arranged on a straight line where the axis of the corresponding rotating shaft is located. In this preferred technical solution, the lighting module is arranged on the axis of the corresponding rotating shaft so that when the lighting module rotates around the rotating shaft, the displacement of its spatial position is smaller, and the space occupied during adjustment is also smaller.

[0014] Preferably, each of the lighting modules includes a module dimming mechanism, and the module dimming mechanism includes three ball nuts that are not in the same straight line and three ball screws that cooperate with them. Each of the lighting modules is installed on the rotating arm through the module dimming mechanism. In this preferred technical solution, by adjusting the rotational position of the three ball screws in the corresponding ball nuts, the relative position of each lighting module and the corresponding rotating arm can be adjusted to achieve the dimming of each lighting module. That is, by adjusting the relative position of the lighting area of ​​each lighting module up, down, left, and right, the lighting area generated by each lighting module is combined into the overall design light shape of the vehicle lamp lighting module of the present invention.

[0015] Preferably, the plurality of lighting modules include a high beam lighting module and / or a low beam lighting module. Through this preferred technical solution, by controlling the high beam lighting module and / or the low beam lighting module, the vehicle lamp lighting module of the present invention can form one of a high beam lighting shape, a low beam lighting shape, a high beam lighting shape or a low beam lighting shape.

[0016] Preferably, the bracket is mounted on the vehicle lamp housing and is adapted to rotate relative to the vehicle lamp housing around a vertical axis. In this preferred technical solution, by adjusting the rotation position of the bracket relative to the vehicle lamp housing around the vertical axis, the position of the light pattern formed by the vehicle lighting device of the present invention in the horizontal direction can be adjusted.

[0017] A second aspect of the present invention provides a vehicle headlight, which includes the vehicle lighting device provided by the first aspect of the present invention.

[0018] A third aspect of the present invention provides a vehicle, comprising the vehicle headlight provided by the second aspect of the present invention.

[0019] Through the above technical solution, the multiple lighting modules of the vehicle lighting device of the present invention can be driven by the rotating arm and independently rotate around mutually parallel horizontal rotation axes to achieve synchronous adjustment of the position of the lighting area generated by each lighting module in the V-axis direction. Since the bracket does not rotate around the horizontal axis during the adjustment process, the dimming space required by the vehicle lighting device of the present invention is relatively small. Each lighting module is installed on the rotating arm and rotates under the drive of the rotating arm. There is no need to set a rotating mechanism on the lighting module, so that each lighting module can be arranged more closely and the positioning of the lighting module is more accurate. The driving unit is used to synchronously drive the rotating arm, and the rotating arm drives the multiple lighting units to rotate synchronously, so that the position of the light shape generated by the vehicle lighting device of the present invention is more convenient to adjust. The application of the electric drive mechanism enables the light shape generated by the vehicle lighting device of the present invention to be adjusted in real time, and the adjustment is more convenient and reliable.

[0020] The vehicle headlight made of the vehicle lighting device of the present invention can be made smaller in size because the space occupied by the vehicle lighting device is small and the internal space of the vehicle headlight is well utilized.

[0021] The vehicle of the present invention adopts the vehicle headlight of the present invention, so the volume of the headlight is smaller and the adjustment of the light pattern is more convenient.

[0049] In the present invention, unless otherwise stated, the directions or positional relationships indicated by the directional words used, such as "up, down, front, and rear", are based on the directions or positional relationships indicated by the vehicle lighting device or vehicle headlight of the present invention when installed on the vehicle according to the vehicle's normal driving state.

[0050] In this specification, the terms "first", "second", ... and "ninth" are used for descriptive purposes only and are not to be understood as indicating or suggesting relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first", "second", ... and "ninth" may explicitly or implicitly include one or more of the said features.

[0051] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "setting" or "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0052] The specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention, and the protection scope of the present invention is not limited to the following specific embodiments.

[0053] like Figures 2 to 7 As shown, an embodiment of the vehicle lighting device of the present invention includes a bracket 10, a plurality of rotating arms 40 and a plurality of lighting modules 20. Each rotating arm 40 includes a driving column 41 and a rotating shaft 42; the rotating shafts 42 of each rotating arm 40 are horizontally mounted on the bracket 10 in parallel with each other, so that the rotating arms 40 are arranged in sequence from top to bottom on the bracket 10, and they can be arranged in a diagonal line to the left or right in the vertical direction. Each rotating arm 40 can rotate around the rotating shaft 42 on the bracket 10 driven by its own driving column 41. The plurality of lighting modules 20 are respectively mounted on the plurality of rotating arms 40, so that each lighting module 20 is in the same arrangement state as the rotating arm 40. As shown Figure 7As shown, when the driving column 41 moves upward from the initial state to the first driving column position 41A, the rotating arm 40 rotates in a clockwise direction around the axis line 43 of the rotating shaft 42, and the light emitting direction of the lighting module 20 installed on the rotating arm 40 swings relatively downward, and the corresponding lighting area also moves downward; when the driving column 41 moves downward from the initial state to the second driving column position 41B, the rotating arm 40 rotates in a counterclockwise direction around the axis line 43 of the rotating shaft 42, and the light emitting direction of the lighting module 20 installed on the rotating arm 40 swings relatively upward, and the corresponding lighting area also moves upward. Therefore, by driving the driving column 41 to move up and down, the lighting area formed by each lighting module 20 can be moved up and down in the V-axis direction. Moreover, as shown in FIG. Figure 8 As shown, after the rotating arm 40 rotates around the rotating axis 42, each lighting module 20 rotates around its own rotating axis 43 from the initial position shown by the solid line to the dimming position shown by the dotted line, and each lighting module 20 has a slight swing. Figure 1 Compared with the dimming method of the prior art shown in the figure, the bracket 10 of the vehicle lighting device of the present invention does not produce displacement, and the displacement of the lighting module 20 is smaller, which greatly reduces the space occupied by the vehicle lighting device in the headlight. Compared with setting a rotating mechanism on each lighting module 20, the spacing between the lighting modules 20 is smaller, which also greatly reduces the space occupied by the vehicle lighting device in the headlight.

[0054] In some embodiments of the present invention, Figures 5 to 8 As shown, the vehicle lighting device of the present invention further includes a driving unit 30. The shape of the driving unit 30 is adapted to the arrangement state of the lighting module 20. An upper guide column 31 and a lower guide column 32 are respectively provided at both ends of the driving unit 30, and the axes of the upper guide column 31 and the lower guide column 32 are parallel to each other. The driving unit 30 is installed on the bracket 10 through the upper guide column 31 and the lower guide column 32, and can move up and down relative to the bracket 10. A plurality of waist-shaped holes 33 are provided on the driving unit 30, and a plurality of driving columns 41 are respectively installed in the plurality of waist-shaped holes 33. As shown in FIG. Figure 5As shown, when the driving part 30 moves in the vertical downward direction 90, it drives the multiple driving columns 41 installed in the waist-shaped hole 33 to move downward at the same time, and the multiple rotating shafts 42 rotate synchronously in the counterclockwise direction, and drive each lighting module 20 to rotate counterclockwise accordingly, and the lighting area formed by each lighting module 20 moves synchronously upward in the V-axis direction, and the light shape formed by the vehicle lighting device of the present invention is raised in the V-axis direction. When the driving part 30 moves in the vertical upward direction 91, it drives the multiple driving columns 41 installed in the waist-shaped hole 33 to move upward at the same time, and the multiple rotating shafts 42 rotate synchronously in the clockwise direction, and drive each lighting module 20 to rotate clockwise accordingly, and the lighting area formed by each lighting module 20 moves synchronously downward in the V-axis direction, and the light shape formed by the vehicle lighting device of the present invention is lowered in the V-axis direction. The setting of the waist-shaped hole 33 enables the driving column 41 to move up and down in the waist-shaped hole 33 while also being able to slide left and right in the waist-shaped hole 33 to adapt to the rotational motion trajectory of the driving column 41.

[0055] In some embodiments of the present invention, Figures 4 to 8 As shown, the vehicle lighting device of the present invention further includes a driving mechanism and a connecting rod 70, one end of the connecting rod 70 is connected to the driving mechanism, and the other end is connected to the driving unit 30. The connection between the connecting rod 70 and the driving mechanism and the driving unit 30 can be a fixed connection, a hinge connection, or a ball head connection. When the driving mechanism moves up and down in the vertical direction, it can drive the connecting rod 70 to move up and down, and drive the driving unit 30 to move up and down through the connecting rod 70. When the connection method is a hinge connection or a ball head connection, the transmission device can also reduce the connection stress caused by the non-parallel movement track of the driving mechanism and the movement track of the driving unit 30, so that the synchronous movement of the driving mechanism and the driving unit 30 is smoother and smoother.

[0056] As some embodiments of the vehicle lighting device of the present invention, Figures 4 to 8 As shown, the driving mechanism is an electric driving mechanism 50 and / or a manual driving mechanism 60. The electric driving mechanism 50 can be driven by an electric cylinder, and the telescopic rod of the electric cylinder is connected to the connecting rod 70; it can also be driven by a reduction motor screw, and the slider on the screw is connected to the connecting rod 70. The manual driving mechanism 60 can be connected to the electric cylinder or the slider through a screw structure. When the manual driving mechanism 60 is rotated, the screw structure drives the electric cylinder or the slider to move, thereby driving the connecting rod 70 to drive the driving part 30 to move up and down. This structure can use the manual driving mechanism 60 to drive the lighting module 20 to rotate to achieve dimming when the electric driving mechanism 50 is turned off or fails.

[0057] In some embodiments of the present invention, Figure 5 , Figure 6 and Fig. 9As shown, the lighting module 20 is installed at a position corresponding to the rotating shaft 42 on the rotating arm 40, that is, the center of the lighting module 20 is located on the straight line where the axis of the rotating shaft 42 is located. When the rotating shaft 42 rotates, the lighting module 20 rotates around the center. At this time, the overall spatial displacement of the lighting module 20 is small, which reduces the space requirement during dimming.

[0058] In some embodiments of the present invention, Fig. 9 , Fig.10 As shown, each lighting module 20 is provided with a module dimming mechanism, which includes a first ball screw 81 and a second screw 82 arranged horizontally, a third ball screw 83 arranged directly below the first ball screw 81, and three ball nuts 80 matched therebetween. Each lighting module 20 is mounted on the rotating arm 40 through a corresponding module dimming mechanism. When the second ball screw 82 is driven to rotate by an external tool, the lighting module 20 can be rotated around the line connecting the ball centers of the first ball screw 81 and the third ball screw 83 to achieve left and right dimming of the lighting module 20; when the third ball screw 83 is driven to rotate, the lighting module 20 can be rotated around the line connecting the ball centers of the first ball screw 81 and the second ball screw 82 to achieve up and down dimming of the lighting module 20. The setting of the module dimming mechanism enables each lighting module 20 to achieve individual dimming, so as to adjust the relative position of the lighting area generated by each lighting module 20, so that the lighting area of ​​each lighting module 20 is combined into an ideal designed light shape.

[0059] In some embodiments of the present invention, the plurality of lighting modules 20 include a high beam lighting module and / or a low beam lighting module. Figure 2 As shown, the lighting module 20 includes a first lighting module 20A, a second lighting module 20B, a third lighting module 20C, a fourth lighting module 20D, a fifth lighting module 20E, a sixth lighting module 20F, a seventh lighting module 20G, an eighth lighting module 20H and a ninth lighting module 20I, a total of nine, wherein the first lighting module 20A, the second lighting module 20B and the third lighting module 20C are low-beam lighting modules, and the fourth lighting module 20D, the fifth lighting module 20E, the sixth lighting module 20F, the seventh lighting module 20G, the eighth lighting module 20H and the ninth lighting module 20I are high-beam lighting modules. The lighting modules 20 are arranged in order from top to bottom along the oblique line. Of course, the number of low beam lighting modules and high beam lighting modules is not limited to three and six in the present embodiment, and their arrangement is not limited to the upper and lower arrangement of the low beam lighting modules and the high beam lighting modules in the present embodiment. The low beam lighting modules can also be arranged at the bottom of the vehicle lighting device or even arranged in intervals. However, ultimately, the lighting areas of the low beam lighting modules must be combined into a low beam light shape, and the lighting areas of the high beam lighting modules must be combined into a high beam light shape through the dimming of each lighting module 20.

[0060] In some embodiments of the present invention, the bracket 10 is rotatably connected to the vehicle lamp housing, and the bracket 10 can rotate relative to the vehicle lamp housing around a vertical axis. When the bracket 10 rotates around the vertical axis, the vehicle lighting device of the present invention as a whole swings left and right relative to the vehicle lamp housing, and the low beam light shape and / or high beam light shape formed by it can also move left and right along the H-axis direction of the light shape, completing the left and right dimming of the light shape in the H-axis direction.

[0061] The vehicle headlight and vehicle of the present invention, because they adopt the vehicle lighting device and vehicle headlight of the present invention, also have the beneficial effects brought by the vehicle lighting device of the above-mentioned embodiment.

[0062] In the description of the present invention, the description with reference to the terms "an embodiment", "some embodiments", "an implementation", etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention.
