[0046] The lighting device of a vehicle, such as an automotive fog lamp, is one of the very important safety components in an automobile, and countries around the world attach great importance to the research and development of automotive lighting. In order to improve the safety and comfort of vehicle driving, more and more high-tech components are incorporated into the automotive lighting system. Among them, the lighting device has strict requirements for the beam angle, light intensity, illumination distance, etc. of the emitted light.

[0047] Currently, the beam angle emitted by the lighting device is relatively single, and at the same time, it is difficult to compensate for the angular error generated during the assembly of the vehicle lamp, and there is a relatively high risk of deviation in the emitted light angle of the beam.

[0048] Please refer to Figure 1 , Figure 1 which is the first exploded view of the lighting device of a vehicle lamp according to one or more embodiments of the present application.

[0049] To solve the above problems, the present application provides a vehicle lamp device 1, which includes a housing 10, a light source 20, a trim ring 30, and a lens 40. The housing 10 is formed with a receiving cavity 11, and the receiving cavity 11 has a light outlet 111; the light source 20 is disposed in the receiving cavity 11, and the light source 20 is configured to emit a light beam toward the light outlet 111; the trim ring 30 is located at the light outlet 111, the trim ring 30 is connected to the housing 10, and the trim ring 30 is provided with a first clamping portion 31, and the first clamping portion 31 extends into the receiving cavity 11; at least a part of the lens 40 is located in the receiving cavity 11, the lens 40 is disposed on the optical path of the light beam, and the lens 40 is provided with a second clamping portion 41, and the first clamping portion 31 and the second clamping portion 41 are clamped and matched to suspend the lens 40 on the trim ring 30, wherein the lens 40 can rotate under the cooperation of the first clamping portion 31 and the second clamping portion 41.

[0050] The vehicle lamp device 1 may include, but is not limited to, a fog lamp. The housing 10 can provide support and protection for the light source 20, the trim ring 30, and the lens 40. The light source 20 is located in the receiving cavity 11, and the light source 20 can emit a light beam toward the light outlet 111. The light source 20 can include, but is not limited to, LED lamp beads, etc. The light source 20 can be fixed relative to the housing 10 so that the light source 20 can stably emit a light beam toward the light outlet 111. It should be noted that in some application scenarios, the light source 20 can also move relative to the housing 10. The trim ring 30 is located at the light outlet 111 and is connected to the housing 10 so that the trim ring 30 is fixed relative to the housing 10. The trim ring 30 is located on the optical path of the light emitted by the light source 20. It can be understood that when the light source 20 is a scattering light source 20, the light beam emitted by the light source 20 is likely to cause light leakage in the receiving cavity 11, resulting in glare. The trim ring 30 can be used to block at least a part of the light beam at the light outlet 111, thereby reducing the risk of light leakage of the light beam in the receiving cavity 11. The lens 40 can be used to receive the light beam emitted by the light source 20 and change the optical path of the light beam, thereby changing the emission angle of the light beam. At least a part of the lens 40 is located in the receiving cavity 11. It can be understood that the lens 40 can be completely accommodated in the receiving cavity 11, or a part of it can be located in the receiving cavity 11, and the rest extends out of the receiving cavity 11 through the light outlet 111. In some application scenarios, the trim ring 30 can have a light-shielding portion, and the light-shielding portion is used to block at least a part of the light outlet 111, and the lens 40 can be exposed to the outside through the remaining light outlet 111 not blocked by the light-shielding portion.

[0051] The trim ring 30 is provided with a first clamping portion 31, and the lens 40 is provided with a second clamping portion 41. The first clamping portion 31 and the second clamping portion 41 can be clamped with each other, so that the lens 40 is suspended on the trim ring 30. It can be understood that the lens 40 is suspended on the trim ring 30 and can swing under the cooperation of the first clamping portion 31 and the second clamping portion 41. The swinging of the lens 40 may mean that the first clamping portion 31 and the second clamping portion 41 cooperate to make the lens 40 rotate relative to the housing 10 around a rotation axis y1, so that the lens 40 can receive the light beam emitted by the light source 20 at different incident angles and then emit the light beam at different exit angles, thereby facilitating the adjustment of the light exit angle of the vehicle headlamp device 1.

[0052] Through the above embodiments, the lens 40 is suspended on the trim ring 30 through the first clamping portion 31 and the second clamping portion 41, so as to facilitate the rotation of the lens 40 relative to the housing 10. Thus, the angle of the light beam emitted by the light source 20 can be flexibly adjusted by the swinging of the lens 40, thereby reducing the risk of deviation of the light exit angle of the light beam.

[0053] In some embodiments, the vehicle headlamp device 1 further includes a lamp cover 60. The lamp cover 60 can be sleeved on the trim ring 30 and block the light exit opening 111. The lamp cover 60 is at least partially transparent to enable the light beam to be transmitted to the outside through the lamp cover 60. It can be understood that the lamp cover 60 can reduce the risk of foreign matters such as dust from entering the accommodation cavity 11, and improve the reliability of the vehicle headlamp device 1.

[0054] In some embodiments, the vehicle headlamp device 1 further includes a circuit board and a radiator. The circuit board and the radiator can be disposed in the accommodation cavity. The circuit board can be electrically connected to the light source 20 to control the light beam emitted by the light source 20, and the radiator can dissipate heat for the circuit board and the light source 20.

[0055] Please refer to Figure 2 , Figure 2 which is a schematic diagram of the cooperation between the trim ring and the lens of the vehicle headlamp device according to one or more embodiments of the present application.

[0056] In some embodiments, the first clamping portion 31 is a clamping groove 310, and the second clamping portion 41 is a rotating shaft 410. The rotating shaft 410 is clamped in the clamping groove 310, and the lens 40 can rotate around the axial direction x1 of the rotating shaft 410. The first clamping portion 31 is a clamping groove 310, and the second clamping portion 41 is a rotating shaft 410. The rotating shaft 410 can be clamped in the clamping groove 310. It can be understood that the axial direction x1 of the rotating shaft 410 is the direction of the rotation axis y1 of the lens 40. The clamping groove 310 has a certain rigidity in the light-emitting direction of the light beam, so as to provide sufficient supporting force for the rotating shaft 410, improve the stability of the rotating shaft 410 when rotating in the clamping groove 310, and further alleviate the risk that the rotation axis y1 of the lens 40 deviates during rotation, resulting in a deviation of the light-emitting angle. Thus, by clamping the rotating shaft 410 in the clamping groove 310, the rotating shaft 410 can rotate in the clamping groove 310 around the direction of the rotating shaft 410, so that the lens 40 can rotate around the axial direction x1 of the rotating shaft 410, and then swing relative to the housing 10.

[0057] In some embodiments, the clamping groove 310 at least includes a first groove section 311. The rotating shaft 410 is clamped in the first groove section 311. The width dimension of the first notch 3111 of the first groove section 311 in the radial direction of the rotating shaft 410 is smaller than the radial dimension of the rotating shaft 410. It can be understood that the clamping groove 310 can have a certain elasticity in the width direction of the first notch 3111 to allow the first notch 3111 to expand or contract. It should be noted that the width direction of the first notch 3111 is not the same as the light-emitting direction of the light beam. Optionally, the width direction can be perpendicular to the light-emitting direction of the light beam. During the assembly process of the rotating shaft 410 and the clamping groove 310, when the rotating shaft 410 enters the first groove section 311 through the first notch 3111, under the extrusion of the rotating shaft 410, the first notch 3111 will undergo a certain deformation and expand, so as to facilitate the rotating shaft 410 to enter the first groove section 311. After the rotating shaft 410 enters the first groove section 311, the width dimension of the first notch 3111 shrinks, so as to clamp the rotating shaft 410 in the first groove section 311, and then realize the assembly of the clamping groove 310 and the rotating shaft 410.

[0058] In some embodiments, the clamping groove 310 further includes a second groove section 312. The second groove section 312 is communicated with the first groove section 311. The width dimension of the second notch 3121 of the second groove section 312 in the radial direction of the rotating shaft 410 is larger than the radial dimension of the rotating shaft 410. It can be understood that during assembly, the rotating shaft 410 can enter the first groove section 311 through the second groove section 312. The width dimension of the second notch 3121 is larger than the radial dimension of the rotating shaft 410, so that the rotating shaft 410 can more easily enter the second notch 3121 and can enter the first groove section 311 under the guidance of the side wall of the second groove section 312. Thus, the second groove section 312 facilitates the installation of the rotating shaft 410 and the clamping groove 310 to be more convenient and efficient.

[0059] In some embodiments, in the direction from the second notch 3121 to the first notch 3111, the width dimension of the second slot section 312 gradually decreases. The width dimension of the second slot section 312 gradually decreases in the direction from the second notch 3121 to the first notch 3111, which can facilitate the side wall of the second slot section 312 to gradually guide the rotating shaft 410 into the first slot section 311 during assembly. Thus, the gradually decreasing width dimension of the second slot section 312 further makes the assembly of the rotating shaft 410 and the clamping slot 310 simpler and more efficient.

[0060] In some embodiments, the number of the clamping slots 310 and the rotating shafts 410 is two. The two clamping slots 310 are spaced apart in the axial direction x1, and the two rotating shafts 410 are respectively clamped in the clamping slots 310. Thus, on the rotation axis y1 of the lens 40, the number of the clamping slots 310 and the rotating shafts 410 is two, which greatly improves the rotation stability of the rotating shaft 410 in the clamping slot 310, thereby reducing the risk of the lens 40 shifting when rotating around the rotation axis y1, and further improving the smoothness when adjusting the light emitting angle of the light beam.

[0061] Please refer to Figures 3 - 8 , Figure 3 which is the first schematic structural view of the vehicle headlight device according to one or more embodiments of the present application; Figure 4 which is according to Figure 3 the sectional view of the vehicle headlight device shown along the A-A direction; Figure 5 which is according to Figure 3 the sectional view of the vehicle headlight device shown along the B-B direction; Figure 6 which is the second schematic structural view of the vehicle headlight device according to one or more embodiments of the present application; Figure 7 which is the second exploded view of the vehicle headlight device according to one or more embodiments of the present application; Figure 8 which is the schematic structural view of the connection between the lens and the driving component of the vehicle headlight device according to one or more embodiments of the present application.

[0062] In some embodiments, the lens 40 includes a lens body 42 and an arm 43. The lens body 42 is disposed on the optical path of the light beam. The arm 43 is connected to the lens body 42. The vehicle headlamp device 1 further includes a driving assembly 50. The driving assembly 50 is connected to an end of the arm 43 away from the lens body 42. The driving assembly 50 is configured to drive the arm 43 to swing, so that the lens body 42 swings. The light beam can be transmitted through the lens body 42 and the light output angle is changed. The second clamping portion 41 can be disposed on either the lens body 42 or the arm 43. When there are multiple second clamping portions 41, some of the multiple second clamping portions 41 can also be located on the lens body 42 and the remaining portions can be located on the arm 43. Exemplarily, when the number of the second clamping portions 41 is two, one of the second clamping portions 41 can be disposed on the lens body 42 and the other can be disposed on the arm 43. The two second clamping portions 41 are spaced apart in the direction of the rotation axis y1 of the lens 40. The driving assembly 50 can provide power for the arm 43, so that the lens body 42 swings around the rotation axis y1. Thus, it is convenient to flexibly adjust the light output angle of the light beam through the cooperation of the driving assembly 50 and the arm 43, and the structure is simple, improving the reliability of the vehicle headlamp device 1.

[0063] In some embodiments, the driving assembly 50 includes a moving rod 51. The moving rod 51 is connected to an end of the arm 43 away from the lens body 42. The moving rod 51 is configured to drive the end of the arm 43 away from the lens body 42 to move along the axial direction of the moving rod 51, so that the lens body 42 swings relative to the housing 10. The moving rod 51 can include, but is not limited to, a screw rod, etc. One end of the arm 43 away from the lens body 42 is connected to the moving rod 51. The moving rod 51 can reciprocate in the axial direction of the moving rod 51, thereby driving the end of the arm 43 away from the lens body 42 to also reciprocate in the axial direction of the moving rod 51. And the lens 40 is also suspended from the decorative ring 30 through the first clamping portion 31 and the second clamping portion 41. Therefore, when the end of the arm 43 away from the lens body 42 reciprocates in the axial direction of the moving rod 51, the lens body 42 can swing around the rotation axis y1. Thus, the lens 40 can be driven to swing by the moving rod 51, thereby facilitating the flexible adjustment of the light output angle of the light beam. It should be noted that in some application scenarios, although the moving rod 51 is connected to the arm 43, the moving rod 51 has no supporting force on the arm 43 distributed along the light output direction of the light beam. Correspondingly, in the light output direction of the light beam, the arm 43 also has no pressure on the moving rod 51, so as to alleviate the risk of damage caused by mutual extrusion between the arm 43 and the moving rod 51. At the same time, when the lens 40 rotates around the rotation axis y1, if the moving rod 51 has a supporting force on the arm 43 in the light output direction of the light beam, it will cause the rotation axis y1 to shift, and further lead to the risk of deviation of the light output angle.

[0064] In some embodiments, an abutting portion 431 is provided at one end of the arm 43 away from the lens body 42. The moving rod 51 is formed with a positioning groove 511 that cooperates with the abutting portion 431, and the abutting portion 431 abuts against the side wall of the positioning groove 511. The arm 43 is connected to the moving rod 51 through the abutting portion 431 and can abut against the side wall of the positioning groove 511. The positioning groove 511 can be formed by being recessed or protruding relative to the radial direction of the moving rod 51. In some application scenarios, the positioning groove 511 is provided around the circumferential side of the moving rod 51. It can be understood that the abutting portion 431 is clamped in the positioning groove 511. When the moving rod 51 moves axially, the abutting portion 431 contacts the side wall of the positioning groove 511 and moves axially along the moving rod 51 under the push of the positioning groove 511, so that the arm 43 swings around the rotation axis y1.

[0065] In some embodiments, the surface of the abutting portion 431 in contact with the side wall of the positioning groove 511 is an arc surface 432, and the abutting portion 431 abuts against the side wall of the positioning groove 511 through the arc surface 432. It can be understood that the abutting portion 431 abuts against the side wall of the positioning groove 511 through the arc surface 432 so that the abutting portion 431 and the positioning groove 511 are in contact in a line-plane form. It should be noted that when the abutting portion 431 moves axially along the moving rod 51 with the moving rod 51, compared with the surface-to-surface contact form in which the abutting portion 431 abuts against the side wall of the positioning groove 511 through a plane, the risk of damage to the abutting portion 431 caused by repeated friction with the positioning groove 511 can be alleviated. Thus, the service life of the lens 40 can be extended and the reliability of the headlight device 1 can be improved.

[0066] It should be noted that in actual application scenarios, for the convenience of assembling the abutting portion 431 and the positioning groove 511, there may be a gap between the abutting portion 431 and the side wall of the positioning groove 511 when the moving rod 51 is in a stationary state after assembly. However, during the movement of the moving rod 51, the abutting portion 431 and the side wall of the positioning groove 511 will approach each other until they abut.

[0067] In some embodiments, the housing 10 is further provided with an adjustment hole 12 communicating the accommodation cavity 11 with the outside. A first thread 512 is provided on the moving rod 51, and a second thread 121 is provided on the inner wall of the adjustment hole 12. The moving rod 51 is inserted into the adjustment hole 12 through the first thread 512 and the second thread 121. In this embodiment, the first thread 512 is an external thread, and the second thread 121 is an internal thread. The moving rod 51 and the adjustment hole 12 are connected together by the internal and external threads. It should be noted that compared with only using plugging or other methods, the threaded connection between the moving rod 51 and the adjustment hole 12 has stronger stability and is more conducive to the installation and adjustment of the moving rod 51. Further, through the mutual cooperation of the first thread 512 and the second thread 121, the depth of the moving rod 51 inserted into the adjustment hole 12 can be flexibly adjusted. It can be understood that by controlling the screwing depth of the first thread 512 and the second thread 121, the moving rod 51 can be moved along the axial direction of the moving rod 51. Thus, it is convenient to improve the flexibility of the movement of the moving rod 51 through the first thread 512 and the second thread 121, so as to drive the lens 40 to swing more flexibly, and then it is easy to adjust the light-emitting angle of the light beam.

[0068] In some embodiments, a slot 513 is formed at one end of the moving rod 51 facing the opening of the adjustment hole 12. The driving assembly 50 further includes a first adjustment gear 52. The first adjustment gear 52 is inserted into the slot 513 and can rotate around the axial direction of the moving rod 51 to drive the moving rod 51 to move in the axial direction of the moving rod 51. The first adjustment gear 52 is inserted into the slot 513 and can be in driving connection with the slot 513. Exemplarily, the slot 513 can be an internal hexagonal groove, and the first adjustment gear 52 can form an external hexagonal convex rod in the axial direction. The first adjustment gear 52 is inserted into the slot 513 through the external hexagonal convex rod. When the first adjustment gear 52 rotates around the axial direction, the moving rod 51 can be driven to rotate around the axial direction through the slot 513. It can be understood that when the moving rod 51 rotates around the axial direction, the first thread 512 on the moving rod 51 cooperates with the second thread 121 of the adjustment hole 12, so that the moving rod 51 can move along its axial direction.

[0069] In some embodiments, the drive assembly 50 further includes a second adjustment gear 53, which is at least partially exposed to the outside world and meshed with the first adjustment gear 52. The second adjustment gear 53 meshes with the first adjustment gear 52, and can drive the first adjustment gear 52 to rotate by rotating the second adjustment gear 53, thereby driving the moving rod 51 to move and the lens 40 to swing. The second adjustment gear 53 is at least partially exposed to the outside world, so that the light output angle of the light beam can be adjusted by the second adjustment gear 53 without entering the adjustment hole 12, thereby improving the convenience of adjusting the light output angle. The second adjustment gear 53 can be coaxially arranged with the first adjustment gear 52. In some application scenarios, it can also be meshed with the first adjustment gear 52 in a manner other than coaxial, so as to facilitate the second adjustment gear 53 to rotate in other directions, so as to facilitate the flexible adjustment of the position of the second adjustment gear 53. The radial size of the second adjustment gear 53 can be different from the radial size of the first adjustment gear 52. For example, the radial size of the second adjustment gear 53 is smaller than the radial size of the first adjustment gear 52. In some other embodiments, the housing 10 is further provided with a mounting hole, which is connected to the adjustment hole 12, and the second adjustment gear 53 is arranged in the mounting hole, so that the second adjustment gear 53 is relatively fixed to the housing 10, thereby improving the stability and reliability of the vehicle lamp device 1.

[0070] In some embodiments, the driving assembly 50 further includes a spring 54, which is sleeved on an end of the moving rod 51 away from the first adjusting gear 52 and abuts against the inner wall of the housing 10. It is understandable that the spring 54 will shrink or stretch as the moving rod 51 moves. For example, when the moving rod 51 goes deep into the adjusting hole 12, the spring 54 shrinks and stores potential energy. When the moving rod 51 moves in a direction to exit the adjusting hole 12, the spring 54 releases the potential energy to help the moving rod 51 move.

[0071] In some embodiments, during the assembly of the vehicle lamp device 1, the spring 54 may be first installed into the adjustment hole 12, and then the moving rod 51 may be inserted into the adjustment hole 12, and then the first adjustment gear 52 may be inserted into the slot 513 of the moving rod 51. The first adjustment gear 52 may be sleeved with a sealing ring so that the first adjustment gear 52 is sealed with the adjustment hole 12 through the sealing ring. The light source 20 is installed in the accommodating cavity 11. After the moving rod 51 and the light source 20 are installed, the first clamping portion 31 of the lens 40 may be clamped in the second clamping portion 41 of the decorative ring 30, and then the arm 43 may be inserted into the accommodating cavity 11 through the light outlet 111, and the abutting portion 431 of the arm 43 away from the end of the lens body 42 is inserted into the positioning groove 511 on the moving rod 51, and then the decorative ring 30 is fixedly connected to the housing 10, so that the lens 40 can swing relative to the housing 10 under the drive of the moving rod 51.

[0072] See also Figure 1 and Figures 3 - 8, to solve the above problems, the present application further provides a vehicle lamp device 1, and the vehicle lamp device 1 includes: a housing 10, a light source 20, a lens 40 and a driving assembly 50. The housing 10 is formed with a receiving cavity 11, and the receiving cavity 11 has a light outlet 111; the light source 20 is disposed in the receiving cavity 11, and the light source 20 is configured to emit a light beam toward the light outlet 111; the lens 40 includes a lens body 42 and an arm rod 43. At least a part of the lens body 42 is located in the receiving cavity 11. The lens body 42 is disposed on the optical path of the light beam. The lens body 42 is rotatably connected to the housing 10. The arm rod 43 is connected to the lens body 42 and extends in a direction opposite to the direction in which the light source 20 emits light; the driving assembly 50 includes a moving rod 51. The moving rod 51 is connected to an end of the arm rod 43 away from the lens body 42. The moving rod 51 is configured to drive the end of the arm rod 43 away from the lens body 42 to move along the axial direction of the moving rod 51, so that the lens body 42 swings relative to the housing 10.

[0073] The vehicle lamp device 1 may include, but is not limited to, a fog lamp. The housing 10 can provide support and protection for the light source 20, the decorative ring 30, and the lens 40. The light source 20 is located in the accommodation cavity 11. The light source 20 can emit a light beam toward the light exit 111. The light source 20 can be, including but not limited to, an LED lamp bead, etc. The light source 20 can be fixed relative to the housing 10 so that the light source 20 can stably emit a light beam toward the light exit 111. It should be noted that in some application scenarios, the light source 20 can also move relative to the housing 10. The lens 40 can be used to receive the light beam emitted by the light source 20 and change the optical path of the light beam, thereby changing the exit angle of the light beam. At least part of the lens 40 is located in the accommodation cavity 11. It can be understood that the lens 40 can be completely accommodated in the accommodation cavity 11, or part of it can be located in the accommodation cavity 11, and the rest extends out of the accommodation cavity 11 through the light exit 111. The driving assembly 50 can provide power for the arm 43 to swing the lens body 42 around the rotation axis y1. By the mutual cooperation of the driving assembly 50 and the arm 43, the exit angle of the light beam can be flexibly adjusted, and the structure is simple, improving the reliability of the vehicle lamp device 1. The moving rod 51 can include, but is not limited to, a screw rod, etc. One end of the arm 43 away from the lens body 42 is connected to the moving rod 51. The moving rod 51 can reciprocate axially on the moving rod 51, thereby driving the end of the arm 43 away from the lens body 42 to also reciprocate axially on the moving rod 51. Since the lens body 42 is rotatably connected to the housing 10, when the end of the arm 43 away from the lens body 42 reciprocates axially along the moving rod 51, the lens body 42 can swing around the rotation axis y1. Thus, the lens 40 can be driven to swing by the moving rod 51, thereby facilitating the flexible adjustment of the exit angle of the light beam. It should be noted that although the moving rod 51 is connected to the arm 43, the moving rod 51 has no supporting force distributed along the light beam exit direction on the arm 43. Correspondingly, in the light beam exit direction, the arm 43 also has no pressure on the moving rod 51. Through the above implementation method, the risk of damage caused by mutual extrusion between the arm 43 and the moving rod 51 can be alleviated, and at the same time, when the lens 40 rotates around the rotation axis y1, if the moving rod 51 has a supporting force on the arm 43 in the light beam exit direction, causing the rotation axis y1 to shift, and then resulting in the risk of deviation of the exit angle can also be reduced.

[0074] In some embodiments, the lens 40 may have a hinge portion, and the lens 40 may be rotatably connected to the housing 10 through the hinge portion. The hinge portion may be directly connected to the housing 10 or indirectly connected to the housing 10. Herein, the indirect connection may mean that the headlight device 1 further includes a fixing member, the fixing member is relatively fixed to the housing 10, and the hinge portion is connected to the fixing member so that the lens 40 can rotate relative to the housing 10. It should be noted that the fixing member may be located inside the accommodating cavity 11 or at least partially outside the accommodating cavity 11. In some application scenarios, the housing 10 may be provided with a first connection portion, the fixing member is provided with a second connection portion, and the hinge portion may be respectively connected to the first connection portion and the second connection portion so that the lens 40 rotates relative to the housing 10 through the hinge portion. Exemplarily, the first connection portion and the second connection portion may be crimped to each other to clamp the hinge portion, so that the hinge portion can rotate relative to the housing 10.

[0075] In some embodiments, the lens 40 is provided with a rotating shaft 410, the rotating shaft 410 is rotatably connected to the housing 10, and the lens body 42 can rotate around the axial direction x1 of the rotating shaft 410. In some application scenarios, the housing 10 may be provided with a fixing portion connected to the rotating shaft 410, and the lens 40 can cooperate with the rotating shaft 410 and the fixing portion to swing relative to the housing 10. In some other embodiments, the headlight device 1 may further include a holding member, the holding member is located inside the accommodating cavity 11, and the holding member can be used to connect to the rotating shaft 410 so that the holding member is rotatably connected to the housing 10. Exemplarily, the holding member may have a first groove, the housing 10 may be provided with a second groove, and the first groove and the second groove can cooperate with each other to accommodate the rotating shaft 410. For example, the openings of the first groove and the second groove can communicate with each other so that the rotating shaft 410 can be simultaneously accommodated in the first groove and the second groove, and further the lens 40 is rotatably connected to the housing 10 through the rotating shaft 410.

[0076] In some embodiments, an abutting portion 431 is provided at one end of the arm rod 43 away from the lens body 42, the moving rod 51 is formed with a positioning groove 511 that cooperates with the abutting portion 431, and the abutting portion 431 abuts against the side wall of the positioning groove 511.

The positioning groove 511 may be formed by being recessed or protruding relative to the radial direction of the moving rod 51. In some application scenarios, the positioning groove 511 is disposed around the circumferential side of the moving rod 51. It can be understood that the abutting portion 431 is clamped in the positioning groove 511. When the moving rod 51 moves axially, the abutting portion 431 contacts the side wall of the positioning groove 511 and moves axially along the moving rod 51 under the push of the positioning groove 511, so that the arm rod 43 swings around the rotation axis y1.

[0077] In some embodiments, the surface of the abutting portion 431 that contacts the side wall of the positioning groove 511 is an arc surface 432, and the abutting portion 431 abuts against the side wall of the positioning groove 511 through the arc surface 432. It can be understood that the abutting portion 431 abuts against the side wall of the positioning groove 511 through the arc surface 432, so that the abutting portion 431 contacts the positioning groove 511 in a line-plane form. It should be noted that when the abutting portion 431 moves along the axial direction of the moving rod 51 with the moving rod 51, compared with the surface-to-surface contact form in which the abutting portion 431 abuts against the side wall of the positioning groove 511 through a plane, the risk of damage to the abutting portion 431 caused by repeated friction with the positioning groove 511 can be alleviated. Thus, the service life of the lens 40 can be extended, and the reliability of the headlight device 1 is improved.

[0078] It should be noted that in the actual application scenario, for the convenience of assembling the abutting portion 431 and the positioning groove 511, there may be a gap between the abutting portion 431 and the side wall of the positioning groove 511 after assembly and when the moving rod 51 is in a stationary state. However, during the movement of the moving rod 51, the abutting portion 431 and the side wall of the positioning groove 511 will approach each other until they abut.

[0079] In some embodiments, the housing 10 is further provided with an adjustment hole 12 communicating the accommodation cavity 11 and the outside. The moving rod 51 is provided with a first thread 512, and the inner wall of the adjustment hole 12 is provided with a second thread 121. The moving rod 51 is inserted into the adjustment hole 12 through the first thread 512 and the second thread 121. In this embodiment, the first thread 512 is an external thread, and the second thread 121 is an internal thread. The moving rod 51 and the adjustment hole 12 are connected together by the internal and external threads. It should be noted that compared with only using plug-in and other methods, the threaded connection between the moving rod 51 and the adjustment hole 12 has stronger stability and is easier to install and adjust the moving rod 51. Further, through the mutual cooperation of the first thread 512 and the second thread 121, the depth of the moving rod 51 inserted into the adjustment hole 12 can be flexibly adjusted. It can be understood that by controlling the screwing depth of the first thread 512 and the second thread 121, the moving rod 51 can be moved along the axial direction of the moving rod 51. Thus, it is convenient to improve the flexibility of the movement of the moving rod 51 through the first thread 512 and the second thread 121, so as to drive the lens 40 to swing more flexibly, and then it is easy to adjust the light-emitting angle of the light beam.

[0080] In some embodiments, a slot 513 is formed at one end of the movable rod 51 facing the opening of the adjustment hole 12. The driving assembly 50 further includes a first adjustment gear 52. The first adjustment gear 52 is inserted into the slot 513 and can rotate around the axial direction of the movable rod 51 to drive the movable rod 51 to move along the axial direction of the movable rod 51.

Exemplarily, the slot 513 can be an internal hexagonal groove, and the first adjustment gear 52 can form an external hexagonal convex rod in the axial direction. The first adjustment gear 52 is inserted into the slot 513 through the external hexagonal convex rod.

The second adjustment gear 53 is at least partially exposed to the outside, so that the light output angle of the light beam can be adjusted through the second adjustment gear 53 without entering the adjustment hole 12, improving the convenience of adjusting the light output angle. The second adjustment gear 53 can be coaxially arranged with the first adjustment gear 52. In some application scenarios, it can also be meshed with the first adjustment gear 52 in a non-coaxial manner, so as to facilitate the second adjustment gear 53 to rotate in other directions and facilitate the flexible adjustment of the position of the second adjustment gear 53. The radial dimension of the second adjustment gear 53 can be different from the radial dimension of the first adjustment gear 52. Exemplarily, the radial dimension of the second adjustment gear 53 is smaller than the radial dimension of the first adjustment gear 52. In some other embodiments, the housing 10 is further provided with a mounting hole. The mounting hole is communicated with the adjustment hole 12, and the second adjustment gear 53 is arranged in the mounting hole, so that the second adjustment gear 53 is relatively fixed to the housing 10, improving the stability and reliability of the vehicle lamp device 1.

[0082] In some embodiments, the driving assembly 50 further includes a spring 54. The spring 54 is sleeved on one end of the moving rod 51 away from the first adjusting gear 52 and abuts against the inner wall of the housing 10. The driving assembly 50 further includes a spring 54. The spring 54 is sleeved on one end of the moving rod 51 away from the first adjusting gear 52 and abuts against the inner wall of the housing 10. It can be understood that the spring 54 will be tightened or elongated as the moving rod 51 moves. Exemplarily, when the moving rod 51 extends into the adjusting hole 12, the spring 54 is tightened to store potential energy.
