Description

Technical Field

[0001] This application relates to the field of automotive lighting technology, and more particularly to an optical component, automotive lighting device, and vehicle. Background Technology

[0002] Vehicle lights generally include a light-emitting device, an optical element, and a driver. The optical element is used to change the propagation path of the light emitted by the light-emitting device. The output part of the driver is hinged to the optical element. The driver is used to drive the optical element to move relative to the light-emitting device in order to adjust the light emission mode of the vehicle light.

[0003] In related technologies, the hinge between the optical element and the output part of the driver is often axially limited by a snap-fit. During the process of assembling the optical element and the driver together, a large force needs to be applied to the snap-fit ​​to deform it and then spring back to embed it into the slot, which makes the assembly process inconvenient.

[0004] Therefore, in related technologies, the process of assembling optical elements and drivers is rather inconvenient. Utility Model Content

[0005] This application provides an optical component, a vehicle lighting device, and a vehicle that improves the ease of assembling optical components with a drive mechanism.

[0006] In a first aspect, this application provides an optical assembly for use in vehicle lights. The optical assembly includes an optical component, a drive mechanism, a first hinge, and a first limiting member. The optical component, used to change the propagation path of light, has a first connecting hole. The output end of the drive mechanism has a second connecting hole. The first hinge includes a first shaft portion and a first stop portion. Both the first and second connecting holes mate with the first shaft portion. The first shaft portion has a first mounting hole coaxially disposed therewith. The first stop portion is disposed on the first shaft portion. The first limiting member includes a first rod portion and a first limiting portion. The first rod portion is threaded into the first mounting hole. The first limiting portion is disposed on the first rod portion. Along the axial direction of the first shaft portion, the first stop portion and the first limiting portion are located on opposite sides of the first and second connecting holes, respectively. The optical component and the output end are both confined between the first stop portion and the first limiting portion.

[0007] The optical component provided in this application has a first connecting hole and a second connecting hole that both mate with the first shaft portion of the first hinge member, so that the optical component and the first connector are hinged through the first shaft portion. The first shaft portion is provided with a first stop portion, and the first hinge member is axially limited with the optical component and the output end through the first stop portion. Along the axial direction of the first shaft portion, the first stop portion is located on the same side of the first connecting hole and the second connecting hole, so that the first stop portion does not need to cross the first connecting hole and the second connecting hole during the process of the first shaft portion extending into the first connecting hole and the second connecting hole. This makes it less likely for the first stop portion to obstruct the process of the first shaft portion extending into the first connecting hole and the second connecting hole, making the process of the first shaft portion extending into the first connecting hole and the second connecting hole smoother, and thus making the assembly of the first hinge member, the optical component and the output end more convenient.

[0008] Furthermore, in this application, the first limiting member is connected to the first hinge member. The first limiting portion of the first limiting member is located on the side of the first connecting hole and the second connecting hole away from the first stop. The optical component and the output end are both limited between the first stop and the first limiting portion, making it difficult for the optical component and the output end to detach from the first shaft portion, thus achieving a stable connection between the first hinge member, the optical component, and the output end. The first rod portion of the first limiting member is threaded into the first mounting hole of the first shaft portion. During the process of installing the first limiting member to the first hinge member, it is only necessary to screw the first rod portion into the first mounting hole, without applying a large force to the first limiting member, making the process of installing the first limiting member to the first hinge member more convenient. Moreover, since the first limiting portion is located on the side of the first connecting hole and the second connecting hole away from the first stop portion, during the process of screwing the first rod portion into the first mounting hole, the first limiting portion does not need to cross the first connecting hole and the second connecting hole, making it less likely for the first limiting portion to obstruct the screwing of the first rod portion into the first mounting hole, making the process of installing the first limiting member to the first hinge member more convenient.

[0009] The optical assembly provided in this application makes it easier to assemble the first hinge, the optical component, and the output end, and also makes it easier to install the first limiting member onto the first hinge. Therefore, this application improves the ease of assembling the optical component and the drive mechanism.

[0010] In conjunction with the first aspect, in some possible implementations, the optical component further includes a base, on which the optical component is movably disposed. The driving mechanism includes a slider, a first connector, and a driving component. The slider is slidably connected to the base, and the direction of relative sliding is perpendicular to the axial direction of the first shaft portion. One end of the first connector is rotatably connected to the slider about a first axis, and the other end is an output end. The first axis is parallel to the axial direction of the first shaft portion. The driving component is connected to the slider and is used to drive the slider to slide relative to the base.

[0011] In this way, the driving component causes the slider to slide relative to the base. One end of the first connector is rotatably connected to the slider, and the other end is rotatably connected to the optical component. The first connector can convert the sliding of the slider into the movement of the optical component relative to the base. By adjusting the length of the first connector, the movement trajectory of the optical component relative to the base can be adjusted, making the optical assembly more adaptable.

[0012] In conjunction with the first aspect and the above-described implementations, in some possible implementations, the slider has a third connecting hole, and the first connector also has a fourth connecting hole. The optical assembly further includes a second hinge and a second limiting member. The second hinge includes a second shaft portion and a second stop portion. Both the third and fourth connecting holes mate with the second shaft portion. The second shaft portion has a second mounting hole coaxially disposed therewith. The second stop portion is disposed on the second shaft portion. The second limiting member includes a second rod portion and a second limiting portion. The second rod portion is threaded into the second mounting hole, and the second limiting portion is disposed on the second rod portion. Along the axial direction of the second shaft portion, the second stop portion and the second limiting portion are located on opposite sides of the third and fourth connecting holes, respectively. The first end of the first connector and the slider are both limited between the second stop portion and the second limiting portion.

[0013] In this way, the slider and the first connector are hinged together by the second hinge. The second shaft of the second hinge extends into the third and fourth connecting holes without requiring significant force, resulting in a smooth insertion process. The second limiting member is used to axially limit the slider and the first connector. The second rod of the second limiting member also screws smoothly into the mounting hole of the second hinge, requiring minimal force. This facilitates the assembly of the slider and the first connector, thereby simplifying the assembly of the optical components.

[0014] In conjunction with the first aspect and the above-described implementations, in some possible implementations, the base is formed with a groove extending perpendicular to the first axis, and the optical component is formed with a sliding post whose axial direction is parallel to the axis of the first shaft portion, the sliding post engaging with the groove. The drive mechanism further includes a second connecting member, one end of which is rotatably connected to the base about a second axis, and the other end of which is rotatably connected to the first connecting member about a third axis. The second axis is parallel to the third axis, and the third axis, the first axis, and the axis of the first shaft portion are all parallel.

[0015] In this way, as the slider slides relative to the base, the optical component rotates relative to the slide groove around the axis of the sliding column on the one hand, and slides relative to the slide groove along the extension direction of the slide groove on the other hand, which makes the movement range of the optical component large, thereby enabling the vehicle lamp device to produce more light emission modes.

[0016] In combination with the first aspect and the above-mentioned implementation, in some possible implementations, one of the optical component and the output end is formed with a first mounting groove, the depth direction of the first mounting groove is from the first stop to the first limiting part, and the first mounting groove cooperates with the first stop.

[0017] By aligning the first mounting slot with the first stop, the stability of the hinge in the optical components and output end is improved, as is the flatness of the outer surface of the optical components, which facilitates the arrangement of the optical components within the vehicle headlight.

[0018] In combination with the first aspect and the above implementation, in some possible implementations, the side wall of the first mounting groove is recessed to form a limiting cavity, and the peripheral surface of the first stop is formed with a limiting protrusion, and the limiting cavity and the limiting protrusion cooperate.

[0019] By engaging the limiting cavity with the limiting protrusion, the first mounting groove can circumferentially limit the first stop, thereby making it difficult for the first hinge to rotate around its own axis relative to either the optical component or the output end. Thus, during the process of screwing the first rod into the first mounting hole of the first hinge, the first hinge is limited by the first mounting groove and is not easy to rotate around its own axis with the first rod, which helps to improve the ease of installation of the first rod.

[0020] In combination with the first aspect and the above implementation, in some possible implementations, the number of second connecting holes is at least two, the at least two second connecting holes are arranged opposite each other, the first connecting hole is located between the two second connecting holes, the first connecting hole and the two second connecting holes adjacent to the first connecting hole are all engaged with the same first shaft portion, and along the axial direction of the first shaft portion, the first stop portion and the first limiting portion are respectively located on opposite sides of the two adjacent second connecting holes.

[0021] By positioning the first connecting hole between the two second connecting holes, and ensuring that both the first connecting hole and the two adjacent second connecting holes mate with the same first shaft portion, the portions of the first shaft portion located on both sides of the first connecting hole are in contact with the output end and are securely mounted to the output end. This helps reduce the bending of the first shaft portion caused by the optical components, thereby improving the stability and mounting accuracy of the optical components at the output end. Furthermore, by positioning the first stop and the first limiting portion on opposite sides of the two connecting holes along the axial direction of the first shaft portion, the first stop portion does not need to pass through the first and second connecting holes during the insertion of the first shaft portion. This improves the ease of installation of the first hinge member. Similarly, the first limiting portion does not need to pass through the first and second connecting holes during the insertion of the first rod portion into the first mounting hole, thus improving the ease of installation of the limiting member.

[0022] In combination with the first aspect and the above-described implementation, in some possible implementations, the distance between the inner circumferential surface of one of the first connecting holes and the outer circumferential surface of the first shaft portion is 0.01 to 0.05 mm, and the distance between the inner circumferential surface of the other and the outer circumferential surface of the first shaft portion is 0 mm.

[0023] By making the distance between the inner circumferential surface of one of the first and second connecting holes and the first shaft portion slightly larger, the overall resistance encountered by the first shaft portion during insertion into the first and second connecting holes is reduced, which improves the ease of insertion. By making the distance between the inner circumferential surface of the other of the first and second connecting holes and the first shaft portion smaller, the installation stability of the first shaft portion in the first and second connecting holes is higher, which helps to reduce the wobbling of the first shaft portion, thereby reducing the relative wobbling between the output end and the optical component. The smaller amplitude of the relative wobbling between the output end and the optical component improves the motion accuracy of the optical component during movement relative to the base, and makes it less likely for the optical component to wobble to a position with high contact stress with the output end, thus reducing the jamming phenomenon during the relative rotation of the output end and the optical component.

[0024] Secondly, this application provides a vehicle lighting device, which includes a light-emitting element and an optical component provided in the first aspect of this application. The light-emitting element is used to emit light, and the optical component is used to change the optical path of the light.

[0025] The vehicle lighting device provided in this application, including the optical components provided in the first aspect of this application, can achieve the same technical effect, namely, it can improve the ease of assembling the optical components with the drive mechanism.

[0026] Thirdly, this application provides a vehicle that includes the lighting device provided in the second aspect of this application.

[0027] The vehicle provided in this application, including the vehicle lighting device provided in the first aspect of this application, can achieve the same technical effect, namely, it can improve the ease of assembling optical components and drive mechanisms. Attached Figure Description

[0048] This application provides a vehicle, which, by way of example, can be a sedan, an off-road vehicle, or a sport utility vehicle (SUV).

[0049] The vehicle provided in this application includes a lighting device. Exemplarily, the lighting device may be a headlight, taillight, or turn signal, etc.

[0050] The vehicle lighting device provided in this application includes a light-emitting element and an optical component. The light-emitting element is used to emit light, and the optical component is used to change the propagation path of the light.

[0051] Please refer to Figures 1 to 4 The optical assembly provided in this application includes an optical component 1, a driving mechanism 2, a first hinge 3, and a first limiting member 4. The optical component 1 is used to change the propagation path of light and has a first connecting hole 11. The output end of the driving mechanism 2 has a second connecting hole 221. The first hinge 3 includes a first shaft portion 31 and a first stop portion 32. Both the first connecting hole 11 and the second connecting hole 221 are engaged with the first shaft portion 31. The first shaft portion 31 is coaxially provided with a first mounting hole 311. The first stop portion 32 is disposed on the first shaft portion 31. The first limiting member 4 includes a first rod portion 41 and a first limiting portion 42. The first rod portion 41 is threaded into the first mounting hole 311. The first limiting portion 42 is disposed on the first rod portion 41. Along the axial direction of the first shaft portion 31, the first stop portion 32 and the first limiting portion 42 are located on opposite sides of the first connecting hole 11 and the second connecting hole 221, respectively. The optical component 1 and the output end are both limited between the first stop portion 32 and the first limiting portion 42.

[0052] In the optical component provided in this application embodiment, the first connecting hole 11 and the second connecting hole 221 both cooperate with the first shaft portion 31 of the first hinge member 3, so that the optical component 1 and the first connector 22 are hinged through the first shaft portion 31. The first shaft portion 31 is provided with a first stop portion 32. The first hinge member 3 axially limits the optical component 1 and the output end through the first stop portion 32. Along the axial direction of the first shaft portion 31, the first stop portion 32 is located on the same side of the first connecting hole 11 and the second connecting hole 221, so that the first stop portion 32 does not need to cross the first connecting hole 11 and the second connecting hole 221 during the process of the first shaft portion 31 extending into the first connecting hole 11 and the second connecting hole 221. This makes it less likely that the first stop portion 32 will obstruct the process of the first shaft portion 31 extending into the first connecting hole 11 and the second connecting hole 221, making the process of the first shaft portion 31 extending into the first connecting hole 11 and the second connecting hole 221 smoother, thereby making the assembly of the first hinge member 3, the optical component 1 and the output end more convenient.

[0053] Furthermore, in this embodiment, the first limiting member 4 is connected to the first hinge member 3. The first limiting portion 42 of the first limiting member 4 is located on the side of the first connecting hole 11 and the second connecting hole 221 away from the first stop portion 32. The optical component 1 and the output end are both limited between the first stop portion 32 and the first limiting portion 42, making it difficult for the optical component 1 and the output end to detach from the first shaft portion 31, thus achieving a stable connection between the first hinge member 3, the optical component 1, and the output end. The first rod portion 41 of the first limiting member 4 is threaded into the first mounting hole 311 of the first shaft portion 31. During the process of installing the first limiting member 4 to the first hinge member 3, it is only necessary to screw the first rod portion 41 into the first mounting hole 311, without applying a large force to the first limiting member 4, making the process of installing the first limiting member 4 to the first hinge member 3 more convenient. Furthermore, the first limiting part 42 is located on the side of the first connecting hole 11 and the second connecting hole 221 away from the first stop part 32, so that during the process of the first rod part 41 being screwed into the first mounting hole 311, the first limiting part 42 does not need to pass through the first connecting hole 11 and the second connecting hole 221, so that the first limiting part 42 is less likely to obstruct the first rod part 41 from being screwed into the first mounting hole 311, making it more convenient to install the first limiting member 4 to the first hinge member 3.

[0054] The optical components provided in this application embodiment are relatively easy to assemble, and the first limiting member 4 is also relatively easy to install onto the first hinge member 3. Therefore, this application embodiment improves the ease of assembling the optical component 1 and the drive mechanism 2.

[0055] Furthermore, in this embodiment, the first shaft portion 31 is formed with a first mounting hole 311, and the first rod portion 41 of the first limiting member 4 is threadedly engaged with the first mounting hole 311. Compared to forming an external thread on the first shaft portion 31 and threading the first limiting member 4 with the external thread, this embodiment can reduce the radial length of the first limiting member 4, which is beneficial to improving the compactness of the structure.

[0056] Please refer to Figures 1 to 4 For example, in the embodiments of this application, the optical component 1 may be a reflector or a lens, etc.

[0057] Please refer to Figures 1 to 4 It should be explained that, in this embodiment, the output end of the drive mechanism 2 and the optical component 1 are hinged through the first shaft portion 31 of the first hinge member 3, so that the drive mechanism 2 can drive the optical component 1 to move relative to the light-emitting element. During the movement of the optical component 1 relative to the light-emitting element, the optical component 1 also rotates relative to the output end. The movement of the optical component 1 relative to the light-emitting element allows the position of the optical component 1 relative to the light-emitting element to be switched, thereby enabling the vehicle lighting device to switch between multiple light-emitting modes, such as switching between low beam mode and enhanced high beam mode.

[0058] Please refer to Figures 1 to 4 Generally, in the embodiments of this application, the first connecting hole 11 and the second connecting hole 221 are arranged opposite each other along the axial direction. This facilitates the insertion of the first shaft portion 31 into the first connecting hole 11 and the second connecting hole 221.

[0059] Please refer to Figures 1 to 4 In this embodiment of the application, the output end and the optical component 1 are hinged by the first shaft portion 31 of the first hinge member 3. This can be achieved by the first connecting hole 11 rotating with the first shaft portion 31 and the second connecting hole 221 being relatively fixed to the first shaft portion 31, or by the second connecting hole 221 rotating with the first shaft portion 31 and the first connecting hole 11 being relatively fixed to the first shaft portion 31, or by both the first connecting hole 11 and the second connecting hole 221 rotating with the first shaft portion 31.

[0060] Please refer to Figures 1 to 4 It is understood that in the embodiments of this application, the first rod portion 41 and the first shaft portion 31 are coaxially arranged, and the axial direction of the first shaft portion 31 is referred to the first direction in the figure.

[0061] Please refer to Figures 1 to 4 In some embodiments of this application, along the axial direction of the first shaft portion 31, the surface of the first stop portion 32 near the first limiting portion 42 can abut against the end face of one of the first connecting hole 11 and the second connecting hole 221, and the surface of the first limiting portion 42 near the first stop portion 32 can abut against the end face of one of the first connecting hole 11 and the second connecting hole 221, so that the optical component 1 and the output end are both limited between the first stop portion 32 and the first limiting portion 42.

[0062] Please refer to Figures 1 to 4 In some embodiments of this application, the first hinge 3 and the first limiting member 4 can be made of metal. This makes the first hinge 3 and the first limiting member 4 have higher strength and smoother outer surfaces, which is beneficial for smoother relative rotation between the output end and the optical component 1, and also helps to improve the installation accuracy of the first hinge 3 in the first connecting hole 11 and the second connecting hole 221, as well as the installation accuracy of the first limiting member 4 and the first hinge 3.

[0063] Please refer to Figures 1 to 4In some embodiments of this application, the optical component 1 has a first connecting portion, a first connecting hole 11 formed in the first connecting portion, and an output end including a second connecting portion, a second connecting hole 221 formed in the second connecting portion. The material of the first connecting portion can be polyoxymethylene, nylon, or tetrafluoroethylene, and the material of the second connecting portion can also be polyoxymethylene, nylon, or tetrafluoroethylene. This helps to reduce the frictional resistance between the inner circumferential surface of the first shaft portion 31 and the first connecting hole 11, and also helps to reduce the frictional resistance between the inner circumferential surface of the first shaft portion 31 and the second connecting hole 221.

[0064] Please refer to Figures 1 to 4 In some embodiments of this application, the optical component further includes a base, the light-emitting element is fixedly connected to the base, and the optical component 1 is movably disposed on the base. The driving mechanism 2 includes a slider 21, a first connecting member 22, and a driving component. The slider 21 is slidably connected to the base, and the direction of relative sliding is perpendicular to the axial direction of the first shaft portion 31. One end of the first connecting member 22 is rotatably connected to the slider 21 around a first axis, and the other end is an output end. The first axis is parallel to the axial direction of the first shaft portion 31. The driving component is connected to the slider 21 and is used to drive the slider 21 to slide relative to the base.

[0065] In this way, the driving component causes the slider 21 to slide relative to the base. One end of the first connector 22 is rotatably connected to the slider 21, and the other end is rotatably connected to the optical component 1. The first connector 22 can convert the sliding of the slider 21 into the movement of the optical component 1 relative to the base. By adjusting the length of the first connector 22, the movement trajectory of the optical component 1 relative to the base can be adjusted, making the optical assembly more adaptable.

[0066] Please refer to Figures 1 to 4 It is understood that, in the embodiments of this application, during the sliding of the slider 21 relative to the base, the first connecting member 22 rotates relative to the slider 21, and the optical component 1 rotates relative to the first connecting member 22.

[0067] Please refer to Figures 1 to 4In some embodiments of this application, the slider 21 has a third connecting hole 211, and the first connector 22 also has a fourth connecting hole 222. The optical assembly also includes a second hinge 5 and a second limiting member 6. The second hinge 5 includes a second shaft portion 51 and a second stop portion 52. The third connecting hole 211 and the fourth connecting hole 222 are both engaged with the second shaft portion 51. The second shaft portion 51 is coaxially provided with a second mounting hole. The second stop portion 52 is disposed on the second shaft portion 51. The second limiting member 6 includes a second rod portion 61 and a second limiting portion 62. The second rod portion 61 is threadedly engaged with the second mounting hole. The second limiting portion 62 is disposed on the second rod portion 61. Along the axial direction of the second shaft portion 51, the second stop portion 52 and the second limiting portion 62 are respectively located on opposite sides of the third connecting hole 211 and the fourth connecting hole 222. The first end of the first connector 22 and the slider 21 are both limited between the second stop portion 52 and the second limiting portion 62.

[0068] In this way, the slider 21 and the first connecting member 22 are hinged by the second hinge member 5. During the process of the second shaft portion 51 of the second hinge member 5 extending into the third connecting hole 211 and the fourth connecting hole 222, no large force needs to be applied to the second hinge member 5, and the extension process is relatively smooth. The second limiting member 6 is used to axially limit the slider 21 and the first connecting member 22. The process of the second rod portion 61 of the second limiting member 6 screwing into the mounting hole of the second hinge member 5 is also relatively smooth, requiring no large force to be applied to the second limiting member 6. This makes the assembly of the slider 21 and the first connecting member 22 more convenient, thereby making the assembly of the optical components more convenient.

[0069] Please refer to Figures 1 to 4 Generally, in the embodiments of this application, the third connecting hole 211 and the fourth connecting hole 222 are arranged opposite each other along the axial direction. This facilitates the insertion of the first shaft portion 31 into the third connecting hole 211 and the fourth connecting hole 222.

[0070] Please refer to Figures 1 to 4 In some embodiments of this application, along the axial direction of the second shaft portion 51, the surface of the second stop portion 52 near the second limiting portion 62 can abut against the end face of one of the third connecting hole 211 and the fourth connecting hole 222, and the surface of the second limiting portion 62 near the second stop portion 52 can abut against the end face of one of the third connecting hole 211 and the fourth connecting hole 222, so that the slider 21 and the first connecting member 22 are both limited between the second stop portion 52 and the second limiting portion 62.

[0071] Please refer to Figures 1 to 4 In some embodiments of this application, the second hinge 5 can also be made of metal, and the second limiting member 6 can also be made of metal. This makes the second hinge 5 and the second limiting member 6 have higher strength and smoother outer surfaces, which is beneficial for smoother relative rotation between the first connecting member 22 and the slider 21.

[0072] Please refer to Figures 1 to 4 In some embodiments of this application, the slider 21 has a third connecting portion, a third connecting hole 211 is formed in the third connecting portion, the first connecting member 22 includes a fourth connecting portion, a fourth connecting hole 222 is formed in the fourth connecting portion, the material of the third connecting portion can be polyoxymethylene, nylon or tetrafluoroethylene, and the material of the fourth connecting portion can be polyoxymethylene, nylon or tetrafluoroethylene. This helps to reduce the frictional resistance between the inner circumferential surface of the second shaft portion 51 and the third connecting hole 211, and also helps to reduce the frictional resistance between the inner circumferential surface of the second shaft portion 51 and the fourth connecting hole 222.

[0073] Please refer to Figures 1 to 4 In some embodiments of this application, the base is formed with a groove, the extension direction of which is perpendicular to the first axis. The optical component 1 is formed with a sliding column 112, the axial direction of which is parallel to the axis of the first shaft portion 31. The sliding column 112 engages with the groove. The drive mechanism 2 further includes a second connecting member 23, one end of which is rotatably connected to the base about a second axis, and the other end of which is rotatably connected to the first connecting member 22 about a third axis. The second axis and the third axis are parallel, and the third axis, the first axis, and the axis of the first shaft portion 31 are parallel.

[0074] In this way, during the sliding of the slider 21 relative to the base, the optical component 1 rotates relative to the slide groove around the axis of the slide post 112 on the one hand, and slides relative to the slide groove along the extension direction of the slide groove on the other hand, so that the movement range of the optical component 1 is large, thereby enabling the vehicle lamp device to produce more light emission modes.

[0075] Please refer to Figures 1 to 4 Of course, in some embodiments of this application, the connection between the optical component 1 and the base can also be in other forms. For example, the optical component 1 can be rotatably connected to the base, and the axis of relative rotation is parallel to the axis of the first shaft 31. During the sliding of the slider 21 relative to the base, the optical component 1 is driven to rotate relative to the base. The slider 21, the first connecting member 22 and the optical component 1 constitute the crank slider 21 mechanism.

[0076] Please refer to Figures 1 to 4 Of course, in some embodiments of this application, the driving mechanism 2 can be implemented in other ways. For example, the driving mechanism 2 can include a third connector, one end of which is rotatably connected to the base and the other end is an output end. The axis of rotation of the third connector relative to the base is parallel to the axis of the first shaft 31. During the rotation of the third connector relative to the base, it drives the optical component 1 to move relative to the base.

[0077] Please refer to Figures 1 to 4In some embodiments of this application, one of the optical component 1 and the output end is provided with a first mounting groove 223. The depth direction of the first mounting groove 223 extends from the first stop 32 to the first limiting part 42, and the first mounting groove 223 engages with the first stop 32. By engaging the first mounting groove 223 with the first stop 32, the mounting stability of the hinge in the optical component 1 and the output end is improved, as is the flatness of the outer surface of the optical component, which facilitates the arrangement of the optical component within the vehicle lamp.

[0078] Please refer to Figures 1 to 4 In some embodiments of this application, one of the optical component 1 and the output end is provided with a second mounting groove 224. The depth direction of the second mounting groove 224 extends from the first limiting portion 42 to the first stop portion 32, and the second mounting groove 224 engages with the first limiting portion 42. By engaging the second mounting groove 224 with the first limiting portion 42, the installation stability of the first limiting member 4 is improved, and the flatness of the outer surface of the optical component is also improved, facilitating the arrangement of the optical component within the vehicle lamp.

[0079] Please refer to Figure 2 , Figure 5 and Figure 6 In some embodiments of this application, the first limiting portion 42 is constructed as a first frustum. The first frustum is coaxial with the first shaft portion 31, and its diameter gradually increases in the direction away from the first stop portion 32. This is beneficial for increasing the contact area between the outer peripheral surface of the first limiting portion 42 and the second mounting groove 224, and for improving the installation stability of the first limiting member 4.

[0080] Please refer to Figure 2 , Figure 5 and Figure 6 In some embodiments of this application, a first cross groove 421 is formed on the surface of the first frustum away from the first rod portion 41. The first cross groove 421 is used to engage with the head of a screwdriver. This facilitates the installation of the first limiting member 4 by the operator using a screwdriver to tighten the first limiting member 4.

[0081] Please refer to Figures 1 to 4 In some embodiments of this application, one of the slider 21 and the first connector 22 may also be formed with a third mounting groove, the depth direction of which points from the second stop 52 to the second limiting part 62, and the third mounting groove cooperates with the second stop 52.

[0082] Please refer to Figures 1 to 4 In some embodiments of this application, one of the slider 21 and the first connector 22 may also be formed with a fourth mounting groove, the depth direction of which points from the second limiting part 62 to the second stop part 52, and the fourth mounting groove cooperates with the second limiting part 62.

[0083] Please refer to Figures 1 to 4 In some embodiments of this application, the second limiting portion 62 may also be configured as a second frustum. The second frustum is coaxial with the second shaft portion 51, and the diameter of the second frustum gradually increases in the direction away from the second stop portion 52.

[0084] Please refer to Figures 1 to 4 In some embodiments of this application, a second cross groove is formed on the surface of the second frustum away from the second rod portion 61. The second cross groove is used to engage with the head of a screwdriver. This facilitates the installation of the second limiting member 6 by the operator using a screwdriver to tighten the second limiting member 6.

[0085] Please refer to Figures 1 to 4 In some embodiments of this application, the large end diameter of the second frustum can be 2.8 ± 0.1 mm, the axial length of the second frustum can be 0.6 to 0.7 mm, and the cone angle of the second frustum can be 90 to 92 degrees.

[0086] Please refer to Figures 1 to 4 In some embodiments of this application, the surface of the second frustum protrudes along one side of the axial direction to form a second rod portion 61. In some embodiments of this application, the axial length of the second limiting member 6 can be 4.6 to 5.0 mm, the diameter of the second rod portion 61 can be 1.2 mm, and the pitch can be 0.25 mm.

[0087] Please refer to Figure 2 , Figure 7 and Figure 8 In some embodiments of this application, the sidewall of the first mounting groove 223 is recessed to form a limiting cavity, and the peripheral surface of the first stop 32 is formed with a limiting protrusion. The limiting cavity and the limiting protrusion cooperate. By making the limiting cavity cooperate with the limiting protrusion, the first mounting groove 223 can circumferentially limit the first stop 32, thereby making it difficult for the first hinge 3 to rotate around its own axis relative to either the optical component 1 or the output end. Thus, during the process of screwing the first rod 41 into the first mounting hole 311 of the first hinge 3, the first hinge 3 is limited by the first mounting groove 223 and is not easy to rotate around its own axis with the first rod 41, which helps to improve the ease of installation of the first rod 41.

[0088] Please refer to Figure 2 , Figure 7 and Figure 8In some embodiments of this application, the first stop 32 can be constructed as a first regular hexagonal prism, which is a columnar structure with a cross-section of a first regular hexagon. The central axis of the first regular hexagonal prism coincides with the central axis of the first shaft 31, and the cross-section of the first regular hexagonal prism is the section of the first regular hexagonal prism perpendicular to the axis of the first shaft 31. It can be understood that in this embodiment, the number of limiting protrusions is six, which are the six corners of the first regular hexagonal prism. This makes the circumferential positioning of the first stop 32 and the first mounting groove 223 more stable, and makes the shape of the first stop 32 simpler and easier to manufacture.

[0089] Please refer to Figures 1 to 4 In some embodiments of this application, the sidewall of the third mounting groove may be recessed to form a locking cavity, and the peripheral surface of the second stop 52 may be protruded to form a locking block, which engages with the locking cavity. In some embodiments of this application, the second stop 52 may also be constructed as a second regular hexagonal prism, which is a columnar structure with a cross-section of a second regular hexagon, and the central axis of the second regular hexagonal prism coincides with the central axis of the second shaft 51.

[0090] Please refer to Figures 1 to 4 In some embodiments of this application, the distance between opposite sides of the second regular hexagon can be 2.5 ± 0.05 mm, the distance between opposite corners of the second regular hexagon can be 2.89 mm, and the axial length of the second regular hexagonal prism can be 1.4 ± 0.05 mm.

[0091] Please refer to Figures 1 to 4 In some embodiments of this application, the surface of the second regular hexagonal prism protrudes along one side of the axial direction to form a second shaft portion 51. In some embodiments of this application, the axial length of the second shaft portion 51 can be 6.0±0.2 mm, the diameter can be 1.6 mm, the diameter tolerance is 0 to 0.05 mm, and the diameter of the second mounting hole can be 1.2 mm and the depth is 4±0.2 mm.

[0092] Please refer to Figures 1 to 4 In some embodiments of this application, the number of second connecting holes 221 is at least two, and the at least two second connecting holes 221 are arranged opposite to each other. The first connecting hole 11 is located between the two second connecting holes 221. The first connecting hole 11 and the two second connecting holes 221 adjacent to the first connecting hole 11 are all engaged with the same first shaft portion 31. Along the axial direction of the first shaft portion 31, the first stop portion 32 and the first limiting portion 42 are respectively located on opposite sides of the two adjacent second connecting holes 221.

[0093] By positioning the first connecting hole 11 between the two second connecting holes 221, both the first connecting hole 11 and the two second connecting holes 221 adjacent to the first connecting hole 11 mate with the same first shaft portion 31. This ensures that the portions of the first shaft portion 31 located on both sides of the first connecting hole 11 are in contact with the output end and are securely installed at the output end. This helps to reduce the bending of the first shaft portion 31 caused by the action of the optical component 1, thereby improving the stability and installation accuracy of the optical component 1 at the output end. By positioning the first stop 32 and the first limiting part 42 on opposite sides of the two connecting holes along the axial direction of the first shaft 31, the first stop 32 does not need to pass through the first connecting hole 11 and the second connecting hole 221 during the process of inserting the first shaft 31 into the first connecting hole 11 and the second connecting hole 221. This improves the ease of installation of the first hinge member 3. It also ensures that the first limiting part 42 does not need to pass through the first connecting hole 11 and the second connecting hole 221 during the process of inserting the first rod 41 into the first mounting hole 311. This further improves the ease of installation of the limiting member.

[0094] Please refer to Figures 1 to 4 It should be explained that, in this embodiment of the application, the two adjacent second connecting holes 221 are located on opposite sides of the first connecting hole 11 along the axial direction.

[0095] Please refer to Figure 9 In some embodiments of this application, the output end forms multiple sets of second connection hole groups. Each set of second connection hole groups includes two opposing and adjacent second connection holes 221. A first connection hole 11 is provided between the two second connection holes 221 in each set of second connection hole groups. The number of first hinge members 3 and first limiting members 4 is also multiple. The first hinge members 3, first limiting members 4 and second connection hole groups are arranged in a one-to-one correspondence. In this way, the output end and the optical component 1 are installed together through multiple first hinge members 3 and multiple first limiting members 4, and the stability of the installation is improved.

[0096] Please refer to Figure 10 In some embodiments of this application, the surface of the first stop 32 near the first limiting part 42 may abut against one of the output end and the optical component 1, while the surface of the first limiting part 42 near the first stop 32 may abut against the other of the output end and the optical component 1, so that both the optical component 1 and the output end are confined between the first stop 32 and the first limiting part 42. Based on this, please refer to... Figure 11 In some embodiments of this application, the number of the first connecting hole 11, the second connecting hole 221, the first hinge 3 and the first limiting member 4 can all be multiple, and the first connecting hole 11, the second connecting hole 221, the first hinge 3 and the first limiting member 4 are provided in a one-to-one correspondence.

[0097] Please refer to Figures 1 to 4 In some embodiments of this application, the number of fourth connecting holes 222 may be at least two, with at least two fourth connecting holes 222 arranged opposite to each other. The third connecting hole 211 is located between the two fourth connecting holes 222. The third connecting hole 211 and the two fourth connecting holes 222 adjacent to the third connecting hole 211 are all engaged with the same second shaft portion 51. Along the axial direction of the second shaft portion 51, the second stop portion 52 and the second limiting portion 62 are respectively located on opposite sides of the two fourth connecting holes 222.

[0098] Please refer to Figures 1 to 4 In some embodiments of this application, the first connector 22 may also form multiple sets of fourth connecting hole groups. Each set of fourth connecting hole groups includes two opposite and adjacent fourth connecting holes 222. A third connecting hole 211 is provided between the two fourth connecting holes 222 in each set of fourth connecting hole groups. The number of second hinge members 5 and second limiting members 6 is also multiple, and the second hinge members 5, second limiting members 6 and fourth connecting hole groups are arranged in a one-to-one correspondence. In this way, the first connector 22 and the slider 21 are installed together through multiple second hinge members 5 and multiple second limiting members 6, and the stability of the installation is improved.

[0099] Please refer to Figures 1 to 4 In some embodiments of this application, the surface of the second stop 52 near the second limiting part 62 may abut against one of the first connecting member 22 and the slider 21, while the surface of the second limiting part 62 near the second stop 52 may abut against the other of the first connecting member 22 and the slider 21, so that both the slider 21 and the first connecting member 22 are limited between the second stop 52 and the second limiting part 62. Based on this, in some embodiments of this application, the number of the third connecting hole 211, the fourth connecting hole 222, the second hinge member 5, and the second limiting member 6 may each be multiple, with each of the third connecting hole 211, the fourth connecting hole 222, the second hinge member 5, and the second limiting member 6 corresponding to one another.

[0100] Please refer to Figures 1 to 4 In some embodiments of this application, the distance between the inner circumferential surface of the first connecting hole 11 and the outer circumferential surface of the first shaft portion 31 is 0.01 to 0.05 mm, for example, 0.03 mm, and the distance between the inner circumferential surface of the other connecting hole 11 and the outer circumferential surface of the first shaft portion 31 is 0 mm.

[0101] By making the distance between the inner circumferential surface of one of the first connecting holes 11 and 221 and the first shaft portion 31 slightly larger, the overall resistance encountered by the first shaft portion 31 during insertion into the first connecting holes 11 and 221 is reduced, which improves the ease of insertion. By making the distance between the inner circumferential surface of the other of the first connecting holes 11 and 221 and the first shaft portion 31 smaller, the installation stability of the first shaft portion 31 in the first connecting holes 11 and 221 is higher, which helps to reduce the sway of the first shaft portion 31, thereby reducing the relative sway between the output end and the optical component 1. The smaller amplitude of the relative sway between the output end and the optical component 1 helps to improve the motion accuracy of the optical component 1 during movement relative to the base, and makes it less likely for the optical component 1 to sway to a position with high contact stress with the output end, thus reducing the jamming phenomenon during the relative rotation of the output end and the optical component 1.

[0102] Please refer to Figures 1 to 4 In some embodiments of this application, the first connecting hole 11 and the two second connecting holes 221 adjacent to the first connecting hole 11 all mate with the same first shaft portion 31.

This helps to reduce the obstruction encountered by the first shaft portion 31 during its insertion into the first connecting hole 11 and the two second connecting holes 221.

[0103] Please refer to Figures 1 to 4 In some embodiments of this application, the distance between the inner circumferential surface of one of the third connecting hole 211 and the outer circumferential surface of the second shaft portion 51 may be 0.01 to 0.05 mm, for example, 0.03 mm. The distance between the inner circumferential surface of the other of the third connecting hole 211 and the outer circumferential surface of the second shaft portion 51 may be 0 mm.

[0104] Please refer to Figures 1 to 4 In some embodiments of this application, the third connecting hole 211 and the two fourth connecting holes 222 adjacent to the third connecting hole 211 all mate with the same second shaft portion 51. The distance between the second shaft portion 51 and the inner circumferential surface of the third connecting hole 211 is 0 mm, and the distance between the second shaft portion 51 and the inner circumferential surface of the two fourth connecting holes 222 is 0.01 to 0.05 mm. This helps to reduce the obstruction encountered by the second shaft portion 51 during its insertion into the third connecting hole 211 and the two fourth connecting holes 222.
