The connection line of the two support grooves is arranged at a certain angle with the light path, and the edge functional area of the fluorescent wheel in the fluorescent wheel assembly is on the same axis as the optical centers of the second lens assembly and the third lens assembly.

[0006] In this technical solution, by providing two support grooves on the base, the two support grooves are not on the same horizontal line, the connection line of the two support grooves is arranged at a certain angle with the optical path, and the fluorescent wheel assembly is located directly above the second lens assembly, which makes the installed base more stable while reducing the volume. The volume of the entire device is reduced without affecting the propagation of the optical path.

[0087] In addition, in the description of the present application, the terms "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0088] According to an embodiment provided by the present invention, as Figure 1-2 shown, an intelligent laser vehicle headlight includes: a housing 10, an upper cover 30, the upper cover 30 is disposed on the upper end of the housing 10, and a laser assembly 20, a first lens assembly 100, a diffuser assembly 200, a second lens assembly, a fluorescent wheel assembly 300, a third lens assembly, a first reflector assembly, a fourth lens assembly 700, a DMD chip assembly 800, a second reflector assembly, and a projection assembly 900 that are fixedly arranged on the housing 10 and arranged in sequence along the optical path. In a specific implementation, the laser assembly 20 is connected to the housing 10, and a heat dissipation device is provided on the laser assembly 20 for dissipating heat from the laser emission device. The laser generated by the laser emission device sequentially passes through the first lens assembly 100, the diffuser assembly 200, the second lens assembly, the fluorescent wheel assembly 300, the third lens assembly, the first reflector assembly, the fourth lens assembly 700, the DMD chip assembly 800, the second reflector assembly, and finally is projected out through the projection assembly 900.

[0089] As Figure 12 、 Figure 17 and Figure 20As shown, the fluorescent wheel assembly 300 is installed directly above the second lens assembly. The fluorescent wheel assembly 300 includes a base 310. At the lower end of the base 310 close to the second lens assembly, two support grooves for supporting the base 310 are spaced apart, namely the first support groove 315a and the second support groove 315b. The connection line of the two support grooves is set at a certain angle with the light path. And the edge functional area of the fluorescent wheel 350 in the fluorescent wheel assembly 300 is on the same axis as the optical centers of the second lens assembly and the third lens assembly. In this embodiment, two support grooves are provided on the support base 310, and the two support grooves are arranged in a staggered manner. Corresponding support parts for installing the second lens assembly 400 are provided on the outer shell 10. Support parts corresponding to the support grooves are provided on the support seat for supporting the base 310, so as to play a better supporting role for the base 310 during use, make the installed base 310 more stable and not prone to shaking, and the support seat and the base 310 are arranged at the same vertical position, which can reduce the overall volume of the lighting device;

[0090] Reference Figure 3-6 As shown, in specific implementation, the first lens assembly 100 includes a first lens 130 and a lens fixing structure. The lens fixing structure includes a mounting seat 110 and a fixing member 120. An installation groove 111 adapted to the first lens 130 is provided on the mounting seat 110. The edge part of the first lens 130 is placed in the installation groove 111. The first lens 130 is formed by extending inward from the inner bottom wall of the outer shell 10. In the process of specific implementation, the mounting seat 110 and the outer shell 10 are integrally formed; the edge of the first lens 130 is circular, and the corresponding installation groove 111 on the mounting seat 110 is arc-shaped and adapted to the edge of the first lens 130. The arc-shaped installation groove 111 can partially support the edge of the first lens 130, so that when installing the first lens 130, the first lens 130 can be quickly positioned.

[0091] To better fix the first lens 130, refer to Figure 6As shown, the fixing member 120 includes a fixing portion 121, an extending portion 126, and two clamping portions 122. Both ends of the fixing portion 121 are detachably mounted on the upper end of the mounting base 110. Both ends of the fixing portion 121 extend towards the same side to form the extending portion 126. The two clamping portions 122 are formed by the extending portions 126 at both ends extending towards each other. The clamping portions 122 are arranged at an angle with the fixing portion 121. The width of the clamping portions 122 is adapted to the width of the outer periphery of the first lens 130 and is used to abut against the outer periphery of the first lens 130 to fix the first lens 130. The extending portion 126 extending from the fixing portion 121 makes the width of the extending portion 126 wider than the width of the fixing portion 121, so that the width of the non-extended part is narrower than that of both ends. The two clamping portions 122 are arranged facing each other. In this embodiment, the clamping portions 122 and the fixing portion 121 are integrally formed, and the clamping portions 122 have elasticity, so that the clamping portions 122 have good elastic deformation. The clamping portions 122 can provide a pre-tightening force and can abut well against the upper end surface of the first lens 130, so that the first lens 130 can be well fixed together. Compared with rigid fixing, the fixing is more firm and not prone to loosening. In this embodiment, the clamping portions 122 extend obliquely upward from the extending portion 126, and the angle between the clamping portions 122 and the extending portion 126 is an obtuse angle, so that the clamping portions 122 can better fit the edge of the first lens 130 and the fixing effect is better. In specific implementation, the fixing member 120 is not limited to the above-described shape, and other similar deformations are also within the protection scope of the present invention. In specific implementation, the clamping portions 122 may not be integrally formed with the fixing portion 121. The two may be separately formed components, as long as the clamping portions 122 and the fixing portion 121 are adjustably connected together, the two are arranged at an angle, and the connected clamping portions 122 can generate a certain pre-tightening force to provide sufficient fastening force for the first lens 130 to facilitate fixing the first lens 130; moreover, the connected clamping portions 122 also have a range of elastic changes, so that even in harsh environments such as bumps and vibrations during the use of the vehicle lamp lighting device, it will not affect the shaking of the first lens 130, nor will it cause the optical center of the first lens 130 to deviate from the first optical path; the clamping portions 122 are arranged at intervals in the width direction with respect to the fixing portion 121, avoiding the influence of the fixing portion 121 on the clamping portions 122, so that the clamping portions 122 can ensure better pre-tightening force and can better fix the first lens 130.

[0092] Referring to Figure 5As shown, in order to make the fixing process faster and the operation more convenient, during implementation, two first positioning portions 112 are provided on the mounting base 110. The two first positioning portions 112 facilitate quick and accurate positioning during positioning. A first positioning hole 125 matching the first positioning portion 112 is provided in the extension portion 126 of the fixing member 120. The fixing member 120 is pre-positioned by the first positioning portion 112. A first mounting hole 124 matching the mounting base 110 is provided on the fixing portion 121 for locking the fixing member 120 to the mounting base 110. In this embodiment, the fixing member 120 is fixed to the first mounting hole 124 by bolts. During specific implementation, it is not limited to the above-mentioned mounting method. The fixing member 120 can also be fixed in the form of a buckle. In this application document, other fixing forms of the fixing member 120 are not elaborated too much.

[0093] Referring again to Figure 5 As shown, similarly, in order to quickly position the first lens 130, the placement groove 111 includes a main groove and two inner grooves 113. The two inner grooves 113 are arranged on both sides of the main groove to form the placement groove 111. The depth from the inner bottom wall of the main groove to the notch of the placement groove 111 is greater than the depth from the inner bottom walls of the two inner grooves 113 to the notch of the placement groove 111, so that the edges and corners on both sides of the first lens 130 are placed in the two inner grooves 113. During specific implementation, the placement groove 111 is set as a profiling groove matching the outer shape of the first lens 130, and the side walls of the profiling groove can better fit on both side walls of the first lens 130. The two inner grooves 113 are arranged on both sides inside the placement groove 111, so that the middle part of the inner bottom wall of the placement groove 111 bulges away from the housing 10. The protruding part inside the placement groove 111 fits with the peripheral side of the first lens 130, and the edges and corners on both sides of the first lens 130 are placed in the two inner grooves 113; the inner side walls on both sides of the opening of the placement groove 111 are inclined away from each other, so that the opening of the opening groove is in an "eight" shape, enabling the first lens 130 to fit better with the first lens 130 when placed in the placement groove 111. Even if there are burrs or unprocessed areas at the edges and corners during the processing of the lens, it does not affect the placement of the first lens 130 in the placement groove 111, and the placement groove 111 can also play a positioning role. The placement groove 111 is set as a main groove and two inner grooves 113, which can not only quickly play a positioning role, but also prevent the situation where burrs appear on the edge of the first lens 130 due to the processing of the first lens 130 and it cannot be installed. This enables the installer to install more quickly and efficiently.

[0094] Preferably, referring again to Figure 6As shown, the fixing member 120 further includes a reinforcing portion 123. The reinforcing portion 123 is formed by flanging the side of the fixing portion 121 away from the clamping portion 122 in a direction away from the first lens 130, and the reinforcing portion 123 forms a certain angle with the fixing portion 121. In a specific implementation, the fixing portion 121 and the reinforcing portion 123 are perpendicularly arranged. The setting of the reinforcing portion 123 makes the fixing member 120 have stronger rigidity, avoiding deformation of the fixing member 120 during use, ensuring the rigidity of the fixing member 120, that is, ensuring the rigidity of the fixing portion 121, so that the first lens 130 can be better fixed together during the fixing process.

[0095] As shown in FIGS. 7-11, the diffuser sheet assembly 200 in the intelligent vehicle lamp includes a diffuser sheet 240 and a diffuser sheet fixing structure. The diffuser sheet fixing structure is used to mount the diffuser sheet 240 so that the diffuser sheet 240 can be better arranged on the optical path; as Figure 8-10 shown, the diffuser sheet fixing structure is used to be mounted on the inner bottom wall of the housing 10. Among them, the diffuser sheet fixing structure includes a fixing base 210 and a pressing member 220. The fixing base 210 is used to be fixed on the housing 10. A light-transmitting hole 216 is formed in the fixing base 210. A pressing groove 211 (as Figure 8 shown) is formed on one side side wall of the fixing base 210 along the edge of the light-transmitting hole 216 for placing the non-functional area at the edge of the diffuser sheet 240.

[0096] It should be noted that, referring again to Figure 8-9 shown, the edge of the diffusing edge is located in the pressing groove 211, and the edge of the diffuser sheet 240 is a non-functional area, which will not have any influence on the light passing through the diffuser sheet 240. At the same time, the light passing through the diffuser sheet 240 will pass through the light-transmitting hole 216 and shoot towards the second lens assembly 400, and then pass through the edge of the fluorescent wheel 350 after passing through the second lens assembly 400, and thus shoot towards the third lens assembly 500. Two protrusions 213 extend outward from the side of the fixing base 210 close to the housing 10. First fixing holes 214 are formed in the protrusions 213 for being fixed on the inner bottom wall of the housing 10 so as to be able to better fix the fixing base 210, so that the fixed fixing base 210 can keep the optical center of the diffuser sheet 240 on the optical path of the entire intelligent vehicle lamp.

[0097] In this embodiment, the pressing member 220 is detachably mounted on a side wall of the fixing base 210 adjacent to the pressing groove 211. The pressing member 220 is provided with a pressing portion 223, and a part of the pressing portion 223 abuts against the outer wall of the diffusion sheet 240. In specific implementation, the pressing groove 211 has a square structure, and the pressing portion 223 is located at the edge intersection of the pressing groove. In this embodiment, the design of the pressing portion 223 can better fit the outer shape design of the diffusion sheet 240, and the pressing portion 223 presses the four corners of the diffusion sheet 240 without affecting the overall use effect of the diffusion sheet 240. Similarly, in order not to affect the use effect of the diffusion sheet 240, the area pressed by the pressing portion 223 is a non-functional area of the diffusion sheet 240, without affecting the normal use of the function. During specific use, the pressing portion 223 can press the non-functional area at the corners of the edge of the diffusion sheet 240, so that the diffusion sheet 240 can achieve the best effect in terms of fastening degree and use effect. In specific implementation, the light-transmitting hole 216 has a rectangular structure, and the inner side wall of the pressing groove 211 at the corner of the light-transmitting hole 216 has an arc-shaped structure; the arc-shaped inner side wall at the corner of the pressing groove 211 facilitates the placement and assembly of the diffusion sheet 240. Even if there are burrs on the edge of the diffusion sheet 240, it will not affect the installation of the diffusion sheet 240.

[0098] Refer to Figure 10As shown, specifically, the fixing base 210 includes: a supporting portion 217, side edges 218, and a mounting portion 219. A light-transmitting hole 216 and a pressing groove 211 are formed on the supporting portion 217; the side edges 218 are connected to both sides of the supporting portion 217 for strengthening the supporting portion 217; the mounting portion 219 is connected to the lower ends of the supporting portion 217 and the side edges 218. In a specific implementation, the side edges 218 are in a triangular structure. The side edges 218 connect the supporting portion 217 and the mounting portion 219, which can better strengthen the supporting portion 217. During actual production, the supporting portion 217, the side edges 218, and the mounting portion 219 are integrally formed to make the use effect of the entire fixing base 210 better; for easy installation, a second mounting hole is formed on the fixing base 210 for fixing the pressing member 220 on the fixing base 210. The position of the second mounting hole is formed near the edge of the pressing groove 211 so that the pressing member 220 can better fix the diffusion sheet 240. In order to fix the fixing base 210 better and prevent the optical center of the diffusion sheet 240 from deviating from the optical path after the fixing base 210 is fixed, in a specific implementation, two protrusions 213 are formed by extending the side of the mounting portion 219 close to the outer shell 10 towards the inner bottom wall of the outer shell 10. The two protrusions 213 are exactly the same, preventing the fixing base 210 from being skewed after installation due to the uneven bottom of the mounting portion 219 during the molding of the fixing base 210. In this embodiment, the protrusions 213 are designed on the side of the mounting portion 219 close to the inner bottom wall of the outer shell 10 and are connected by screws, so that the position of the fixing base 210 can be adjusted by screws, thereby better correcting the position of the fixing base 210. A second positioning hole 215 is formed on the mounting portion 219, and a positioning structure is correspondingly arranged on the inner bottom wall of the outer shell 10 to quickly install the fixing base 210 on the outer shell 10.

[0099] As Figure 11As shown, specifically, the pressing member 220 has a flaky structure. The pressing piece further includes a connecting portion 224. Both ends of the connecting portion 224 extend towards the same side to form a pressing portion 223. In specific implementation, the pressing portion 223 and the connecting portion 224 are integrally formed. The pressing portion 223 is located at the edge intersection of the pressing groove 211 and is used to press the edge corners of the diffusion sheet 240. The intersection of the pressing portion 223 and the connecting portion 224 has an arc-shaped structure, so that when the pressing portion 223 presses the diffusion sheet 240, sufficient pre-tightening force can be provided, making the fixing effect of the diffusion sheet 240 better. In specific implementation, the pressing member 220 in this embodiment can also be designed as a frame structure, surrounding the edge of the pressing groove 211, and the pressing portion 223 thereon can fit on the edge of the diffusion sheet 240. In this embodiment, the specific shape of the pressing member 220 is not specifically limited. As long as the pressing member 220 is provided with a pressing portion 223, the pressing member 220 is arranged adjacent to the pressing groove 211, and the pressing portion 223 can better press the edge of the diffusion sheet 240. As for other shapes of the pressing member 220, there are not too many restrictions in this embodiment. The designed pressing member 220 needs to be designed with a pressing portion 223, and the pressing portion 223 can provide sufficient pre-tightening force and can abut against the non-functional area at the edge of the diffusion sheet 240, so that the diffusion sheet 240 is firmly installed without affecting its use.

[0100] Referring to Figure 12 As shown, preferably, a plurality of second positioning portions 212 extend from the side wall of the fixing base 210 where the pressing member 220 is installed. Corresponding third positioning holes 222 are formed on the pressing member 220 for positioning the pressing piece by the second positioning portions 212. A locking hole 221 is formed between the two third positioning holes 222 for fixing the pressing member 220 on the fixing base 210 by passing a locking member 230 through the locking hole 221 and the second mounting hole. During installation, the second positioning portions 212 play a role of pre-positioning, making the installation process more rapid and convenient. In this embodiment, the number of pressing members 220 is two, which are respectively located on the upper and lower sides of the light-transmitting hole 216. The two pressing pieces are arranged oppositely, and the pressing portions 223 on the two pressing members 220 are arranged close to each other to respectively press the edges of the diffusion sheet 240.

[0101] As Figure 13-20As shown, the fluorescent wheel assembly 300 includes a fluorescent wheel 350 and a fixing structure for fixing the fluorescent wheel 350. The fluorescent wheel fixing structure includes a base 310 and a shock-absorbing component. A second fixing hole 314 is formed on the side wall of the base 310 for mounting the base 310 on the housing 10. An accommodating hole 311 parallel to the optical path is formed on the base 310. The accommodating hole 311 is used to place a part of the rotating device 340 for mounting the fluorescent wheel 350. A gap is provided between the outer wall of the rotating device 340 and the inner wall of the accommodating hole 311. A plurality of locking holes 312 are formed on the side wall of the base 310 adjacent to the side wall of the accommodating hole 311. In a specific implementation, as Figure 14-16 shown, a plurality of accommodating holes 311 are formed on the side wall of the base 310 for mounting on the base 310. The purpose of the accommodating hole 311 is to place the rotating device 340, which facilitates the placement of the rotating device 340. However, the accommodating hole 311 in this embodiment does not play a substantial supporting role for the rotating device 340. A gap is provided between the inner wall of the accommodating hole 311 and the outer wall of the rotating device 340 (as Figure 15 shown), so that when the rotating device 340 drives the fluorescent wheel 350 to rotate, the generated vibration will not be directly transmitted to the base 310.

[0102] As Figure 18-19 shown, in order to enable the installed rotating device 340 to have a better shock-absorbing effect, a shock-absorbing component is designed in this embodiment. The shock-absorbing component includes a shock-absorbing ring 320 and a locking member 330. The shock-absorbing ring 320 is clamped in the locking hole 312. The locking member 330 includes a locking portion 333 and a fitting portion 332. The locking member 330 penetrates through the shock-absorbing ring 320 so that the fitting portion 332 is placed inside the shock-absorbing ring 320, and the locking portion 333 is placed outside the shock-absorbing ring 320. The locking portion 333 is used to lock the rotating device 340 located on the other side of the base 310. By first setting the shock-absorbing ring 320 and then fixing the rotating device 340 in the form of the locking member 330 passing through the shock-absorbing ring 320, after the locking member 330 fixes the rotating device 340, on the one hand, a locking effect can be achieved, and the vibration generated by the rotating device 340 will not be directly transmitted to the base 310, but will be further buffered by the shock-absorbing ring 320.

[0103] In order to achieve better shock absorption effect, preferably, an annular groove 321 is formed on the outer wall of the shock absorption ring 320. The annular groove 321 is used for the shock absorption ring 320 to be clamped in the locking hole 312, and the annular groove 321 and the locking hole 312 are arranged with a gap in the radial direction. In this embodiment, the annular groove 321 on the shock absorption ring 320 is clamped in the locking hole 312, and both sides of the shock absorption ring 320 located on both sides of the annular groove 321 are located on both sides of the base 310. When the locking member 330 is locked, the rotating device 340 is also in direct contact with the shock absorption ring 320, and the locking member 330 will not be in direct contact with the base 310, so that the vibration generated by the rotating device 340 will not be directly transmitted to the base 310, thereby making the shock absorption effect better. At the same time, the annular groove 321 and the locking hole 312 are arranged with a gap in the radial direction. When the rotating device 340 generates vibration, the shock absorption ring 320 will have a certain movement range in the radial direction of the locking hole 312. In the axial direction of the locking member 330, the locking member 330 can closely fit on the shock absorption ring 320, achieving good fixation while having a better shock absorption effect.

[0104] During specific implementation, the locking member 330 is a screw. The screw further includes a fastening portion 331. The fastening portion 331, the fitting portion 332, and the locking portion 333 are sequentially arranged along the axial direction of the screw. The diameter of the fitting portion 332 is larger than that of the locking portion 333. In this embodiment, the locking member 330 is set in a three-stage form. On the one hand, it is convenient for fixation, and on the other hand, it is to reduce the transmission of vibration as little as possible. In this embodiment, one end of the screw away from the locking portion 333 is used for being rotated and fixed by a screwdriver. The fitting portion 332 is completely placed inside the shock absorption ring 320, and the locking portion 333 can better connect with the rotating device 340.

[0105] As Figure 16 shown, in order to make the shock absorption effect better, in this embodiment, the locking hole 312 is arranged on the outer periphery of the placement hole 311, and the locking hole 312 communicates with the placement hole 311. The number of locking holes 312 is three, and the three locking holes 312 are evenly distributed in a ring. And two of the locking holes 312 are arranged in the same horizontal direction. The locking holes 312 evenly distributed in a ring can make the fixed rotating device 340 have a better fixing effect, and each locking member 330 is evenly stressed. At the same time, the locking hole 312 communicates with the placement hole 311, further reducing the vibration generated by the rotating device 340 from being transmitted to the shock absorption ring 320, thereby making the overall shock absorption effect better. Moreover, when placing the shock absorption ring 320, only need to deform the shock absorption ring 320 by hand and then place the shock absorption ring 320 in the locking hole 312 along the position where the placement hole 311 communicates with the locking hole 312.

[0106] In order to better fix the rotating device 340, in specific implementation, several limiting parts 313 extend from one side of the base 310 near one side of the rotating device 340 for limiting the rotating device 340. The rotating device 340 includes a motor and a connecting plate 341 fixedly sleeved outside the motor. The motor is placed in the placement hole 311, and the locking part 330 is connected to the connecting plate 341. A plurality of engaging positions 342 are formed at the edge of the connecting plate 341, and the limiting parts 313 on the base 310 are placed in the engaging positions 342. The limiting parts 313 on the base 310 can well limit the rotating device 340 and quickly position the rotating device 340 to a suitable position, so as to facilitate the locking of the subsequent locking part 330.

[0107] As Figure 1-4 and Figure 21-22 shown, the mirror assembly 600. In this embodiment, the mirror assembly 600 is respectively the first mirror assembly 610 and the second mirror assembly 620. The design, installation, and adjustment methods of the first mirror assembly 610 and the second mirror assembly 620 are the same, and the only difference is their sizes. Specifically, both the first mirror assembly 610 and the second mirror assembly 620 include a fixing plate 632, at least two adjusting rods 633, and an elastic member 634. The fixing plate 632 is used to install the mirror 631; one end of the adjusting rod 633 is connected to the side wall of the fixing plate 632, and the other end of the adjusting rod 633 penetrates through the housing 10 and is locked by a nut 635, and one of them is a reference adjusting rod 633; the elastic member 634 is sleeved on a section of the adjusting rod 633 between the fixing plate 632 and the inner wall of the housing 10.

[0108] In specific implementation, adjustment holes for installing the adjusting rods 633 are formed on the housing 10, and the aperture of the formed adjustment holes is slightly larger than the diameter of the adjusting rods 633, so that when adjusting the adjusting rods 633, the effect of fine adjustment in the left - right or up - down direction can be achieved, and at the same time, it does not affect the fixation of the position of the fixing plate 632. In this embodiment, the elastic member 634 provides an elastic force, which can well fix the fixing plate 632 on the housing 10; in actual implementation, the number of adjusting rods 633 is three, which respectively form the three vertices of an isosceles triangle. Two of the adjusting rods 633 are located on the base of the triangle, and the reference adjusting rod 633 is located at the vertex where the two isosceles sides of the triangle meet, and the other two adjusting rods 633 are located at the two vertex positions of the base of the isosceles triangle. When adjusting, the up - down position is adjusted with the reference adjusting rod 633 as the reference, and the positions of the three adjusting rods 633 are respectively set at the three vertex positions of the isosceles triangle. When adjusting the position, the adjustment of the position can be made more accurate.
