[0065] The present application provides a dimming system, a lighting module and a vehicle.

[0066] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0067] like Figures 1-12 As shown, the embodiment of the present application provides a dimming system 3, which is used to adjust the angle of the light source system 4 of the lighting module. The dimming system 3 includes a transmission bracket 1 and a guide component 2. Figure 3 The transmission bracket 1 includes a pivot portion 11; see the attached Figure 8-12 The pivoting portion 11 is used to pivotally connect to the adjustment position 41 of the light source system 4. Figure 2 The guide assembly 2 includes a guide rod 21 and a slider 22. The guide rod 21 is fixed to the housing 5 of the lighting module. The slider 22 is fixed to the transmission bracket 1 and is movably mounted outside the guide rod 21. This allows the transmission bracket 1 to move along the guide rod 21, thereby driving the pivoting portion 11 to move. The pivoting portion 11 causes the adjustment position 41 of the light source system 4 to deflect relative to the universal pivot position 42 of the light source system, thereby achieving angle adjustment of the light source system 4.

[0068] It should be noted that the dimming system 3 is arranged behind the light source system 4. The light source system 4 includes a bracket and a light source arranged on the bracket; Figure 8-9 The bracket of the light source system 4 includes an adjustment position 41 and a universal pivot position 42. The adjustment position 41 is movably set on the housing 5 through the dimming system 3. The universal pivot position 42 is universally pivoted to the housing 5. The universal pivot position 42 can only rotate relative to the housing 5 without causing any movement or displacement. Furthermore, the adjustment position 41 is provided with a connecting piece. One of the connecting piece and the pivot part 11 is a ball head buckle, and the other is a pivot ball head adapted to be pivoted with the ball head buckle. One of the universal pivot position 42 and the housing 5 relative to the universal pivot position 42 is provided with a ball head buckle, and the other is provided with a pivot ball head adapted to be pivoted with the ball head buckle. The light source of the light source system 4 is an LED.

[0069] Furthermore, the transmission bracket 1 moves under the action of an external force, and the movement of the transmission bracket 1 drives the slider 22 to move. Under the constraint that the slider 22 moves along the guide rod 21 , the transmission bracket 1 moves along the guide rod 21 .

[0070] The dimming system 3 of the present application is provided with a guide assembly 2 that is completely independent of the housing 5, eliminating the need for a slide structure on the injection-molded housing 5. With this arrangement, firstly, the guiding movement of the guide assembly 2 of the dimming system 3 is completely free from the constraints of the housing 5, which not only facilitates the injection molding of the housing 5, but also allows the slider 22 to cooperate with the guide rod 21 with high precision, allowing the slider 22 to constrain the transmission bracket 1 to accurately and reliably guide along the guide rod 21, thereby achieving smooth and reliable movement of the adjustment position 41 driven by the pivot 11, making the angle adjustment movement of the light source system 4 more accurate, reliable, smooth, and free of jamming. The slider 22 constrains the transmission bracket 1 to reciprocate along the guide rod 21, thereby achieving precise resetting of the adjustment position 41 driven by the pivot 11, thereby precisely resetting the light source system 4. Due to the precise resetting of the light source system 4, the light pattern is precisely reset. Secondly, the guide assembly 2 is not restricted by the shape of the housing 5 and can be universally configured as a standard component, applicable to lighting modules of different shapes, saving R&D and design costs.

[0071] Please see the attached Figure 7 In some embodiments of the present application, a ball 221 is embedded in the inner surface of the sliding block 22 and the guide rod 21 so that the sliding block 22 can roll and slide along the guide rod 21.

[0072] A ball 221 is embedded in the slider 22, and the slider 22 moves back and forth along the guide rod 21 under the driving force. The rolling of the ball 221 changes the friction between the slider 22 and the guide rod 21 from sliding friction to rolling friction, thereby reducing the friction coefficient, which not only reduces the friction loss caused by relative motion and extends the service life of the guide component 2; but also can realize the movement of the slider 22 along the guide rod 21 under the driving force of a smaller force; at the same time, further optimizes the accuracy, reliability, stability and smoothness of the dimming movement process; further, the machining accuracy of the ball 221 and the guide rod 21 is also greatly improved compared with the injection molding accuracy of the shell with a slide groove, thereby effectively solving the problems of dimming jamming and inability to reset the light pattern.

[0073] Please see the attached Figure 1-3 5. In certain embodiments of the present application, a slider fixing support 12 is provided on the side of the transmission bracket 1 parallel to its moving direction; the slider 22 is fixed to the slider fixing support 12.

[0074] It should be noted that the moving direction of the transmission bracket 1 is the Figure 5The direction of movement of the transmission bracket 1 is parallel to the guide rod 21. The slider fixing support 12 is disposed on the side of the transmission bracket 1, so the slider 22 mounted on the slider fixing support 12 is also located on the side of the transmission bracket 1. Therefore, the fixed assembly of the guide rod 21 to the housing 5 is not restricted by the transmission bracket 1, and the movement of the slider 22 along the guide rod 21 is not affected by the transmission bracket 1.

[0075] Please see the attached Figure 3 In some embodiments of the present application, the slider fixing support 12 includes a through hole 1211 and first fixing holes 1221 arranged around the through hole 1211. Figure 2 The slider 22 includes a sleeve 222 partially inserted into the through hole 1211 and a fixing member 223 inserted outside the sleeve 222. The fixing member 223 defines a second fixing hole 2231 opposite to the first fixing hole 1221. The first fastener 7 is inserted sequentially through the second fixing hole 2231 and the first fixing hole 1221 to secure the slider 22 to the slider fixing support 12.

[0076] It should be noted that the depth of the first fixing holes 1221 and the second fixing holes 2231 is parallel to the direction of movement of the transmission bracket 1; multiple pairs of first fixing holes 1221 and second fixing holes 2231 are provided one-to-one. The first fixing holes 1221 and the second fixing holes 2231 can be threaded holes or smooth round holes; correspondingly, the first fastener 7 can be a screw, a threaded rod, or a pin.

[0077] By means of the sleeve 222 and the through hole 1211, the positioning assembly of the slider 22 on the slider fixing support 12 is realized; by the docking of the first fixing hole 1221 and the second fixing hole 2231, and the through connection of the first fastener 7 in the above-mentioned two docking holes, the reliable fixed installation of the slider 22 on the slider fixing support 12 is realized, and no misalignment or movement will occur during use; furthermore, the detachable installation of the slider 22 on the slider fixing support 12 is realized by means of the first fastener 7, which facilitates the disassembly, replacement and maintenance of the slider 22.

[0078] In some parallel embodiments, the slider 22 and the slider fixing support 12 may be fixedly mounted in other forms besides the above-described forms. For example, the slider fixing support 12 includes a first half portion and a second half portion fixedly connected to the transmission bracket 1. The first half portion includes a first half-slot and first docking portions located on either side of the first half-slot. The second half portion includes a second half-slot and second docking portions located on either side of the second half-slot. The first docking portion defines a first docking hole, and the second docking portion defines a second docking hole. Dock fasteners are sequentially inserted through the first and second docking holes to achieve fixed connection between the first and second halves. In this case, the first and second half-slots enclose a through-hole 1211. The slider 22 itself is a sleeve structure, and its outer circumference conforms to the shape of the through-hole 1211. After the slider 22 is installed in the first half-slot of the first half portion, the second half portion is docked with the first half portion to achieve fixed installation of the slider 22 within the slider fixing support 12.

[0079] Please see the attached Figure 3 In certain embodiments of the present application, the slider fixing support 12 includes a support body 121 and a boss 122 disposed on the support body 121; a through hole 1211 is formed in the support body 121; and a first fixing hole 1221 is formed in the boss 122. Figure 1-2 The fixing member 223 is a U-shaped structure, and the U-shaped structure covers the boss 122 .

[0080] It should be noted that please refer to the attached Figure 3 The support body 121 is a rectangular parallelepiped structure, with protrusions 122 perpendicularly disposed at each of the four corners of the support body 121. The protrusions 122 are parallel to the guide rod 21. The opening of the U-shaped structure faces the slider fixed support 12. The U-shaped structure can be wrapped around the circumferential sidewalls of the support body 121 (the four sidewalls parallel to the protrusions 122 are spliced together to form the circumferential sidewalls). The opening of the U-shaped structure can also abut the sidewalls of the support body 121 where the protrusions 122 are disposed.

[0081] As described above, the fixing member 223 is used to achieve safety protection for the protruding column 122, thereby preventing collision damage to the protruding column 122 during use, ensuring the structural stability of the dimming system 3, and extending its service life.

[0082] In some parallel embodiments, the slider fixing support 12 itself is a rectangular parallelepiped structure, with the through hole 1211 defined in the center of the slider fixing support 12 and the first fixing hole 1221 defined on the outer periphery of the slider fixing support 12. The fixing member 223 itself is a fixing block structure, with the second fixing hole 2231 defined in the fixing block. When the slider 22 is mounted on the slider fixing support 12, the fixing block and the slider fixing support 12 are docked, thereby achieving docking between the first fixing hole 1221 and the second fixing hole 2231.

[0083] Please see the attached Figure 1-6 In certain embodiments of the present application, the guide assembly 2 includes a guide rod fixing support 23, which includes an abutment portion 231. The guide rod fixing support 23 is fixed to the lighting module housing 5. The guide rod fixing support 23 is provided at least at one end of the guide rod 21, so that the end of the guide rod 21 is fixed to the abutment portion 231.

[0084] It should be noted that if only one end of the guide rod 21 is provided with the guide rod fixing support 23, the other end of the guide rod 21 directly abuts against the housing 5. As described above, by providing the guide rod fixing support 23, the guide rod 21 can be conveniently and quickly installed and fixed on the housing 5.

[0085] See attached Figure 4 In certain embodiments of the present application, the guide rod 21 is disposed within the receiving groove 51 of the housing 5, the guide rod fixing support 23 is fixed to the notch of the receiving groove 51, and the ends of the guide rod 21 are respectively fixed to the bottom of the receiving groove and the abutment portion 231 of the guide rod fixing support 23. As described above, by providing only one guide rod fixing support 23, the guide rod 21 can be reliably fixed to the housing 5, resulting in a most streamlined structure and reduced manufacturing costs.

[0086] Please see the attached Figure 6 In some parallel embodiments, the two guide rod fixing supports 23 are respectively fixed to the notch and the bottom of the mounting groove 51, and the two ends of the guide rod 21 are respectively fixed to the abutment portions 231 of the two guide rod fixing supports 23.

[0087] Please see the attached Figure 2 In certain embodiments of the present application, the abutment portion 231 is an abutment groove formed in the guide rod fixing support 23. It should be noted that the abutment portion 231 is recessed away from the guide rod 21 to form the abutment groove. As described above, the abutment groove enables the positioning and installation of the guide rod 21, facilitating precise assembly of the guide rod 21.

[0088] For further information, please see the attached Figure 4 When the end of the guide rod 21 directly abuts against the bottom of the seating groove 51, a bottom abutting groove is formed at the bottom of the seating groove 51, which is recessed away from the guide rod 21, so as to further achieve precise assembly of the guide rod 21 and prevent the guide rod 21 from being dislocated.

[0090] It should be noted that please refer to the attached Figure 4 When only the notch of the placement groove 51 is provided with the guide rod fixing support 23, mounting columns are provided on both sides of the notch of the placement groove 51, and the mounting columns are provided with fourth fixing holes; the guide rod fixing support 23 is supported on the mounting columns. Figure 6 When the guide rod fixing support 23 is also provided at the bottom of the placement groove 51 , two mounting columns with opposite positions are also provided at the bottom of the placement groove 51 .

[0091] Furthermore, the depth direction of the third fixing hole 232 and the fourth fixing hole is parallel to the moving direction of the transmission bracket 1; the third fixing hole 232 and the fourth fixing hole can be threaded holes or smooth round holes; correspondingly, the second fastener 8 can be a screw or a screw rod, or a pin shaft.

[0092] By docking the third fixing hole 232 and the fourth fixing hole, and penetrating and connecting the second fastener 8 in the above-mentioned two docking holes, the guide rod fixing support 23 is reliably fixed and installed on the housing 5, thereby achieving reliably fixed and installed the guide rod 21 in the receiving groove 51, and no misalignment or movement will occur during use; further, the second fastener 8 is used to achieve detachable installation of the guide rod fixing support 23 on the housing 5, which is convenient for disassembly, replacement and maintenance of the guide rod fixing support 23, and detachable installation of the guide rod 21 in the receiving groove 51, which is convenient for disassembly, replacement and maintenance of the guide rod 21.

[0105] As described above, one of the two dimming systems 3 is synchronously driven to adjust the angle of the high beam light source system and the low beam light source system along the up and down direction (i.e., the vertical direction); the other is synchronously driven to adjust the angle of the high beam light source system and the low beam light source system along the left and right direction (i.e., the horizontal direction), thereby reducing the number of settings of the dimming system 3, streamlining the settings of the high and low beam modules, and reducing the occupied space.

[0106] In summary, the present application further provides a vehicle including the lighting module described above. The vehicle includes a drive system 6 for driving the dimming system 3 of the lighting module. Drive system 6 includes at least one of a manual drive system, an electrically controlled drive system, and a signal-controlled real-time drive system.

[0107] As described above, different types of drive systems 6 are used to meet the dimming requirements of vehicles with different configurations, which is flexible and highly applicable.

[0108] Please see the attached Figure 13It should be noted that the drive system 6 includes a manual drive system, which includes a bevel gear set 62, a screw 63, and a screw bracket 64; the bevel gear set 62 includes a meshing first bevel gear 621 and a second bevel gear 622, the first bevel gear 621 rotates around the vertical axis, and the second bevel gear 622 rotates around the horizontal axis; the screw 63 is transmission-connected to the second bevel gear 622; the screw bracket 64 includes a connecting nut, which is threadedly connected to the screw 63; a drive rod 61 is provided on the screw bracket 64, and the end of the drive rod 61 is a pivot ball head, which is pivotally connected to the ball head buckle 132 of the transmission part 13 of the transmission bracket 1. The bevel gear set 62 converts the rotational torque of the first bevel gear 621 rotating around the vertical axis into the rotational torque of the second bevel gear 622 rotating around the horizontal axis. The second bevel gear 622 rotates to drive the screw 63 to rotate. The screw 63 rotates to drive the screw bracket 64 to move linearly along the screw 63. The screw bracket 64 moves to drive the drive rod 61 to move. The drive rod 61 moves to drive the transmission part 13 to move. The movement of the transmission part 13 drives the transmission bracket 1 to move as a whole. The transmission bracket 1 then drives the slider 22 to move, and under the constraint of the slider 22, they are guided to move along the guide rod 21.

[0109] Please see the attached Figure 13 The driving system 6 only includes a manual driving system, and the driver rotates the first bevel gear 621 with a dimming tool; the direction of manual rotation can control the forward and backward directions of the linear motion of the dimming system 3 to control the angle adjustment of the high and low beam lighting module.

[0110] Please see the attached Figure 14 Drive system 6 includes an electrically controlled drive system, which includes a DC motor 65. This motor directly drives the linear motion of drive rod 61. The driver selects the desired dimming angle using a gear switch on the vehicle's dashboard. The gear switch outputs angle change information to DC motor 65, which drives drive rod 61 to move linearly, thereby driving the linear motion of dimming system 3. This angle change information controls the forward and backward directions of the linear motion of dimming system 3, thereby controlling the angle adjustment of the high and low beam lighting modules.

[0111] For further information, please see the attached Figure 14 The driving system includes two types: a manual driving system and an electric control driving system. The DC motor 65 is set on the screw bracket 64 to select the driving type according to actual conditions.

[0112] Please see the attached Figure 15Drive system 6 includes a real-time signal electric control system, which includes a stepper motor 66. This directs the linear motion of drive rod 61. The vehicle outputs an angle-changing LIN or CAN signal to stepper motor 66, which in turn drives dimming system 3 to linear motion in real time. The angle-changing signal controls the forward and backward directions of dimming system 3's linear motion, thereby controlling the angle adjustment of the high and low beam lighting modules.

[0113] For further information, please see the attached Figure 15 The driving system includes two types: a manual driving system and a real-time signal electric control system. The stepping motor 66 is set on the screw bracket 64 to select the driving type according to actual conditions.
