Description

Technical Field

[0001] This utility model relates to the field of vehicle lighting technology, and in particular to a vehicle lighting structure and a vehicle having the vehicle lighting structure. Background Technology

[0002] With the development of automotive lighting technology, more and more automotive lights are exploring the combination of mechanical movement and lighting modes to achieve a cool effect of dynamic mechanical lighting. When the lighting reflector uses mechanical movement to open and close along an angle, errors in the manufacturing of moving parts, product assembly errors, and mechanical transmission clearances can cause errors in the reflector's angle. This results in differences between the reflector's emitted light pattern and the ideal position. Especially for low beam reflectors with high requirements for reflector angle position, a manual adjustment device is usually embedded in the movement mechanism to correct the positional errors caused by manufacturing and movement. The installation cost of the manual adjustment device is high, and the installation process is inconvenient, leaving room for improvement. Utility Model Content

[0042] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0043] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicating the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0044] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0045] Unless otherwise specified, the front-back direction in this application refers to the longitudinal direction of the vehicle, i.e., the X direction; the left-right direction refers to the lateral direction of the vehicle, i.e., the Y direction; and the up-down direction refers to the vertical direction of the vehicle, i.e., the Z direction.

[0046] The following is for reference. Figures 1-14 According to the vehicle lamp structure 100 of this utility model embodiment, the manual worm gear 21 can be reliably limited and installed between the transmission gear ring 23 and the mounting cover plate 3 by installing the cover plate 3, thereby improving the reliability of motion transmission between the manual worm gear 21 and the sector gear 22, so as to improve the reliability of the manual worm gear 21 in adjusting the angle of the reflector bowl 1. Moreover, the manual worm gear 21 is reliably fixed, and the installation of the mounting cover plate 3 is simple, which can reduce the disassembly and maintenance costs.

[0047] like Figures 1-14 As shown, the vehicle headlight structure 100 according to an embodiment of the present utility model includes: multiple reflectors 1, an adjustment structure 2, and a mounting cover 3.

[0048] It should be noted that the basic function of the headlight structure 100 is to provide illumination for the vehicle at night or in low-light environments. The headlight structure 100 can also serve as a signal device. When the vehicle is driving at night, turning on the headlight structure 100 allows other vehicles and pedestrians to determine the vehicle's position and direction of travel. The headlight structure 100 can include low beam illumination and high beam illumination. The low beam illumination is relatively soft, has a wide illumination range, and a low beam height, providing sufficient illumination without posing a danger to other road users, i.e., preventing the light from directly shining into the eyes of oncoming vehicle drivers. The high beam illumination has a longer beam distance. Both low beam illumination and high beam illumination can illuminate the road conditions ahead, and the reasonable switching between low beam illumination and high beam illumination effectively improves the safety of vehicle driving.

[0049] Specifically, the headlight structure 100 includes a reflector bowl 1, which reflects light. There are multiple reflector bowls 1 distributed around the headlight source. This means that multiple reflector bowls 1 can be evenly distributed around the headlight source. After the headlight source emits light, the multiple reflector bowls 1 will reflect and focus the light in a specific direction. Through the focusing effect, the light can be more concentrated and evenly illuminated on the road ahead. Since there are multiple reflector bowls 1, the angle of the reflector bowls 1 relative to the headlight source can be adjusted simultaneously, or the angle of one of the reflector bowls 1 can be adjusted individually. The adjustment method is more flexible and has a wider range, making the light adjustment more appropriate and accurate.

[0050] The headlight structure 100 also includes an adjustment structure 2, which is used to adjust the opening angle of the reflector bowl 1. The adjustment structure 2 includes a manual worm gear 21, a sector gear 22, and a transmission gear ring 23. The manual worm gear 21 is rotatably mounted on the transmission gear ring 23, meaning that the manual worm gear 21 can be mounted on the transmission gear ring 23 and can rotate relative to the transmission gear ring 23. The manual worm gear 21 has a manual adjustment function, so it can be manually operated to rotate relative to the transmission gear ring 23. The sector gear 22 is mounted on the transmission gear ring 23, meaning that the sector gear 22 can be connected through the transmission gear ring 23. The manual worm gear 21 meshes with the sector gear 22 to drive the sector gear 22 to rotate. In other words, through the meshing of the manual worm gear 21 and the sector gear 22, the power of the manual worm gear 21 can be transmitted to the sector gear 22 to achieve the rotation of the sector gear 22. Furthermore, the transmission method between the manual worm gear 21 and the sector gear 22 is equivalent to that of a worm wheel and worm, which can convert a horizontal rotational motion into a vertical rotational motion. The manual worm gear 21 can be used to manually input driving force, making the power transmission operation between the manual worm gear 21 and the sector gear 22 simpler and more convenient, with less manpower consumption and lower cost.

[0051] Furthermore, the sector gear 22 and / or the transmission gear ring 23 are poweredly connected to multiple reflector bowls 1 through the transmission structure 4 so as to drive the multiple reflector bowls 1 to open or close when rotating. That is to say, the sector gear 22 can be poweredly connected to multiple reflector bowls 1 through the transmission structure 4, so that the multiple reflector bowls 1 can open or close relative to the headlight source. Similarly, the transmission gear ring 23 can be poweredly connected to multiple reflector bowls 1 through the transmission structure 4, so that the multiple reflector bowls 1 can open or close relative to the headlight source. In addition, the sector gear 22 and the transmission gear ring 23 can be jointly poweredly connected to multiple reflector bowls 1 through the transmission structure 4, so that the multiple reflector bowls 1 can open or close relative to the headlight source. Through the above three methods, the angle of multiple reflector bowls 1 can be adjusted, and the appropriate method can be selected flexibly according to the actual situation.

[0052] The transmission structure 4 enables the sector gear 22 and / or the transmission gear ring 23 to be connected to the power of multiple reflector bowls 1, so as to enable the sector gear 22 and / or the transmission gear ring 23 to switch the multiple reflector bowls 1 between the closed state and the open state. In actual design, the transmission structure 4 can be constructed as a gear rack, worm gear, or multi-link structure.

[0053] In actual use, the driving force can be manually input into the manual worm gear 21, and the driving force of the manual worm gear 21 is transmitted to the reflector bowl 1 through the sector gear 22 and the transmission structure 4 in sequence, so as to realize the manual adjustment of the opening angle of the reflector bowl 1. The transmission gear ring 23 can realize the power input through automatic drive, and the driving force of the transmission gear ring 23 is transmitted to the reflector bowl 1 through the sector gear 22 and the transmission structure 4 in sequence, so as to realize the automatic adjustment of the opening angle of the reflector bowl 1.

[0054] In actual production, manufacturing errors of moving parts, product assembly errors, and mechanical transmission clearances cause errors in the angle of the reflector bowl 1, resulting in differences in the position of the beam pattern emitted by the reflector bowl 1 compared to the ideal position. Especially for the low beam reflector bowl 1, which has high requirements for the angle position of the reflector bowl 1, when the angle of the automatically driven reflector bowl 1 deviates, the angle of the reflector bowl 1 can be adjusted by the manual worm gear 21 to correct the positional errors caused by manufacturing and movement, so as to ensure that the beam pattern and range reflected by the reflector bowl 1 better meet the set requirements. Moreover, the manual operation of this application is simple, convenient, and low in cost.

[0055] Furthermore, the headlight structure 100 also includes a mounting cover 3, which is mounted on the transmission gear ring 23 and limits the manual worm gear 21 between the mounting cover 3 and the transmission gear ring 23. In this way, the manual worm gear 21 can be reliably mounted on the transmission gear ring 23 through the mounting cover 3.

[0056] The manual worm gear 21 is rotatably mounted on the transmission gear ring 23. A mounting cover plate 3 is placed on the side of the manual worm gear 21 away from the manual worm gear 21 and installed on the transmission gear ring 23. This allows the mounting cover plate 3 to be connected to the transmission gear ring 23, with the manual worm gear 21 located between the mounting cover plate 3 and the manual worm gear 21. In other words, the mounting cover plate 3 can limit the manual worm gear 21 on the side away from the transmission gear ring 23, preventing the manual worm gear 21 from loosening relative to the transmission gear ring 23. This ensures a more reliable installation of the manual worm gear 21 on the transmission gear ring 23, thereby ensuring a more reliable rotation of the manual worm gear 21 relative to the transmission gear ring 23.

[0057] Furthermore, the sector gear 22 is installed on the transmission gear ring 23. That is, the sector gear 22 can be limited by the installation cover plate 3, making the installation of the sector gear 22 and the transmission gear ring 23 more reliable. This ensures that the motion transmission between the manual worm gear 21 and the sector gear 22 is more reliable and stable, thereby improving the reliability of the manual worm gear 21 in adjusting the angle of multiple reflector bowls 1.

[0058] Furthermore, the mounting cover 3 is detachably installed on the transmission gear ring 23, facilitating the connection and disassembly between the mounting cover 3 and the transmission gear ring 23. This detachable connection allows for easy repair and replacement of the manual worm gear 21, sector gear 22, and other structural components after damage. The mounting cover 3 can be connected to the transmission gear ring 23 via screwing, snap-fitting, or other methods, simplifying the connection process, improving the efficiency of mounting and disassembling the mounting cover 3, and reducing maintenance costs.

[0059] According to the vehicle lamp structure 100 of this utility model embodiment, by using a manual worm gear 21, a sector gear 22, a transmission gear ring 23, and multiple reflector bowls 1 in cooperation, the transmission gear ring 23 can automatically adjust the angle of the reflector bowls 1, and the manual worm gear 21 can manually adjust the angle of the reflector bowls 1. Since the angle of the reflector bowls 1 in the vehicle lamp structure 100 may have errors due to manufacturing errors of moving parts, product assembly errors, and mechanical transmission clearances, this application, by adding manual adjustment, ensures that the light pattern and range reflected by the reflector bowls 1 better meet the set requirements, improving the accuracy of the angle adjustment of the reflector bowls 1. Furthermore, the mounting cover plate 3 reliably limits the installation of the manual worm gear 21 between the transmission gear ring 23 and the mounting cover plate 3, thereby improving the reliability and stability of the motion transmission between the manual worm gear 21 and the sector gear 22, thus improving the reliability of the manual worm gear 21 in adjusting the angle of the reflector bowls 1. The manual worm gear 21 is reliably fixed, and the installation of the mounting cover plate 3 is simple, reducing disassembly and maintenance costs. Moreover, the structure is simple, the performance is good, and the application range is wider.

[0060] In some embodiments, the mounting cover 3 is configured to engage with the transmission gear ring 23 along the axial direction of the transmission gear ring 23 and be circumferentially rotatably inserted and fixed relative to the transmission gear ring 23.

[0061] Specifically, by fastening the mounting cover plate 3 to the transmission gear ring 23 along the axial direction, the mounting cover plate 3 can be installed on the transmission gear ring 23 in a direction perpendicular to the radial direction of the transmission gear ring 23, or in a direction parallel to the thickness direction of the transmission gear ring 23. In this way, the mounting cover plate 3 can be fastened to one side of the thickness direction of the transmission gear ring 23, thus covering one side of the thickness direction of the transmission gear ring 23. Furthermore, the axial fastening increases the connection area between the mounting cover plate 3 and the transmission gear ring 23, thereby improving the reliability of the connection between the two.

[0062] Both the manual worm gear 21 and the mounting cover plate 3 can be located on one side of the axial direction of the transmission gear ring 23. By fastening the mounting cover plate 3 to the transmission gear ring 23 along the axial direction, the manual worm gear 21 can be limited and pressed in the axial direction of the transmission gear ring 23, which can restrict the loosening of the manual worm gear 21 in the axial direction and effectively improve the connection reliability between the manual worm gear 21 and the transmission gear ring 23.

[0063] Furthermore, the mounting cover 3 is inserted and fixed relative to the transmission gear ring 23 in a circumferential rotation, which realizes the screw-on connection between the mounting cover 3 and the transmission gear ring 23. For example, the mounting cover 3 can be installed by rotating in either a clockwise or counterclockwise direction along the circumferential direction of the transmission gear ring 23, and the mounting cover 3 and the transmission gear ring 23 are inserted and fixed in a circumferential direction, which can increase the connection area between the mounting cover 3 and the transmission gear ring 23 in the circumferential direction, thereby improving the connection reliability between the mounting cover 3 and the transmission gear ring 23. Moreover, the insertion method is simple and convenient to install.

[0064] Furthermore, when disassembly is required, the mounting cover 3 can be rotated circumferentially along the transmission gear ring 23 in either a clockwise or counterclockwise direction to separate the mounting cover 3 from the transmission gear ring 23, thus achieving the disassembly of the mounting cover 3. The disassembly process is simple and convenient.

[0065] Therefore, through the above settings, the mounting cover plate 3 and the transmission gear ring 23 can be installed by a single rotational insertion, which simplifies the installation and disassembly process, ensures a firm and reliable connection, reduces the installation and disassembly cost of the mounting cover plate 3, and improves the reliability of the mounting cover plate 3 in limiting the manual worm gear 21.

[0066] In some embodiments, one of the mounting cover plate 3 and the transmission gear ring 23 is provided with at least one insertion portion 231 and the other is provided with at least one insertion mating portion 31. When the mounting cover plate 3 rotates relative to the transmission gear ring 23, at least one insertion portion 231 is inserted and fixed into at least one insertion mating portion 31 in a one-to-one correspondence.

[0067] In other words, at least one insertion part 231 can be provided on the mounting cover plate 3, and at least one insertion mating part 31 can be provided on the transmission gear ring 23. Alternatively, at least one insertion part 231 can be provided on the transmission gear ring 23, and at least one insertion mating part 31 can be provided on the mounting cover plate 3. Through these two configuration methods, the mounting cover plate 3 and the transmission gear ring 23 can be connected in the circumferential direction through the insertion connection of at least one insertion part 231 and at least one insertion mating part 31. The configuration methods are diverse and can be flexibly selected.

[0068] Specifically, the number of insertion parts 231 and the number of insertion mating parts 31 are matched. Each insertion part 231 and insertion mating part 31 is set to at least one. At least one insertion part 231 and at least one insertion mating part 31 are distributed in a one-to-one correspondence. In actual installation, the mounting cover plate 3 is rotated relative to the transmission gear ring 23. After at least one insertion part 231 and at least one insertion mating part 31 are inserted and engaged in place, the mounting cover plate 3 and the transmission gear ring 23 can be rotated and fixed. By inserting and engaging at least one insertion part 231 and at least one insertion mating part 31, the connection reliability between the mounting cover plate 3 and the transmission gear ring 23 can be improved.

[0069] In this embodiment, as Figure 1 , Figure 8 and Figure 9 As shown, both the insertion part 231 and the insertion mating part 31 are provided in pairs, with each pair corresponding to the other, thus improving the connection reliability between the mounting cover plate 3 and the transmission gear ring 23. Furthermore, the insertion part 231 and the insertion mating part 31 can also be provided in single or triple configurations. Both the mounting cover plate 2 and the transmission gear ring 23 can be constructed as circular structures, allowing for a better structural match and facilitating the connection between the mounting cover plate 3 and the transmission gear ring 23, thereby enhancing the structural integrity of the vehicle lamp structure 100.

[0070] In some embodiments, the insertion portion 231 includes a wedge-shaped structure, and the insertion mating portion 31 includes a wedge-shaped groove 311. The width of the wedge-shaped structure and the width of the wedge-shaped groove 311 are both configured to gradually increase along the engagement direction.

[0071] Specifically, the wedge-shaped structure and wedge-shaped groove 311 prevent the mounting cover plate 3 from separating from the transmission gear ring 23, making the insertion and engagement of the mounting cover plate 3 and the transmission gear ring 23 more secure and reliable. Figure 8 and Figure 9 As shown, the width of the wedge structure and the width of the wedge groove 311 are both designed to gradually increase along the screwing direction. This allows the wedge structure to gradually insert into the wedge groove 311 when the mounting cover plate 3 moves along the screwing direction, facilitating the insertion and engagement between the two. Furthermore, through the above two settings, the insertion and engagement between the wedge structure and the wedge groove 311 becomes simpler and more reliable, thereby improving the installation convenience and reliability of the mounting cover plate 3, enhancing the stability of the manual worm gear 21 during movement, and improving the ease of disassembly of the mounting cover plate 3.

[0072] At least a portion of the insertion part 231 can be constructed as a wedge-shaped structure, and at least a portion of the insertion mating part 31 can be constructed as a wedge-shaped structure. The wedge-shaped structure is provided with at least one inclined sidewall. Correspondingly, the wedge-shaped groove 311 is provided with at least one inclined inner wall. In this way, after the wedge-shaped structure is inserted into the wedge-shaped groove 311, the wedge-shaped structure and the wedge-shaped groove 311 can be restricted from separating along the inclined direction between them.

[0073] Furthermore, the inclined sidewalls of the wedge-shaped structure can be constructed to be radially inclined along the transmission gear ring 23, and the wedge-shaped structure and the wedge-shaped groove 311 can have a polygonal cross-section. The size of the polygonal cross-section is set to gradually increase in the direction away from the transmission gear ring 23. In this way, after the wedge-shaped structure is inserted into the wedge-shaped groove 311, the radial disengagement of the mounting cover plate 3 from the transmission gear ring 23 is reduced, realizing the self-locking of the mounting cover plate 3 and the transmission gear ring 23, thereby improving the connection reliability between the two. Moreover, the cross-section of the wedge-shaped structure and the wedge-shaped groove 311 can also be set as a triangular cross-section, a quadrilateral cross-section, or other polygonal cross-sections.

[0074] Furthermore, the wedge-shaped structure and the wedge-shaped groove 311 can extend circumferentially along the transmission gear ring 23. The width of the wedge-shaped structure and the wedge-shaped groove 311 is not fixed along the engagement direction, and the width at the initial end along the engagement direction is smaller and the width at the end is larger. This facilitates the gradual insertion of the wedge-shaped structure into the wedge-shaped groove 311 along the engagement direction. The wedge-shaped structure and the wedge-shaped groove 311 are structurally matched, and the width of both the wedge-shaped structure and the wedge-shaped groove 311 is designed to gradually increase along the engagement direction, which can improve the tightness of the connection between the two and thus improve the reliability of the connection. The gradually increasing width of the wedge-shaped structure and the wedge-shaped groove 311 along the engagement direction makes the width change more uniform, resulting in good structural smoothness, low resistance during installation, and effectively improving the connection convenience between the mounting cover plate 3 and the transmission gear ring 23.

[0075] In some embodiments, the transmission gear ring 23 has two rotating support portions 232, each of which has a rotating support groove 233 facing the mounting cover plate 3. The two ends of the manual worm gear 21 are respectively rotatably supported in the two rotating support grooves 233. In this way, the two ends of the manual worm gear 21 can be respectively mounted on the transmission gear ring 23 through the two rotating support grooves 233, thereby improving the stability of the manual worm gear 21 connection.

[0076] Specifically, such as Figure 7 and Figure 8As shown, the transmission gear ring 23 is provided with two rotating support parts 232, and the rotating support parts 232 protrude from the surface of the outer peripheral wall of the transmission gear ring 23. The two rotating support parts 232 are respectively provided with rotating support grooves 233. The rotating support grooves 233 have an open side, which facilitates the installation of the manual worm gear 21 from the open side into the rotating support grooves 233. The open side of the rotating support grooves 233 is open to the mounting cover plate 3, so that when the mounting cover plate 3 is fastened to the transmission gear ring 23 along the axial direction of the transmission gear ring 23, the mounting cover plate 3 can press the manual worm gear 21 located at the open side of the rotating support groove 233, which can prevent the manual worm gear 21 from coming out of the rotating support groove 233, thereby improving the installation reliability and working stability of the manual worm gear 21.

[0077] The two rotating support parts 232 are spaced apart along the circumference of the transmission gear ring 23, that is, the two rotating support grooves 233 are spaced apart along the circumference of the transmission gear ring 23. The two rotating support grooves 233 are respectively provided with corresponding axial ends of the manual worm gear 21, and the two ends of the manual worm gear 21 are provided with two axial limiting parts 213. The two axial limiting parts 213 press against the two rotating support parts 232 on the side away from each other, so that the two axial ends of the manual worm gear 21 are supported in the two rotating support grooves 233 one by one. The two axial limiting parts 213 can axially limit the manual worm gear 21, thereby improving the installation reliability of the manual worm gear 21 and the transmission gear ring 23.

[0078] Furthermore, the two rotating support grooves 233 can be constructed as arc-shaped grooves, and the shape of the two rotating support grooves 233 is matched with the shape of the manual worm gear 21, so that the manual worm gear 21 can be reliably rotated and supported in the rotating support grooves 233. This helps to improve the rotational stability of the manual worm gear 21 relative to the transmission gear ring 23.

[0079] The transmission gear ring 23 has two insertion parts 231, which are respectively connected to two rotating support parts 232. In this way, by connecting the two insertion parts 231 to the two rotating support parts 232, the two insertion mating parts 31 can be brought closer to the corresponding rotating support part 232. The rotating support part 232 has a rotating support groove 233, so that after the two insertion parts 231 and the two insertion mating parts 31 are inserted and mated, the mounting cover plate 3 can be used to fix the manual worm gear 21 at the two rotating support grooves 233, thereby improving the installation reliability of the manual worm gear 21. Furthermore, the connection of the two insertion parts 231 to the two rotating support parts 232 makes the overall structure more compact and facilitates the limiting of the manual worm gear 21 after the mounting cover plate 3 is connected to the transmission gear ring 23.

[0080] Furthermore, the two insertion portions 231 are distributed one-to-one with the two rotating support portions 232, and the two insertion portions 231 can be integrally formed with the two rotating support portions 232, which can improve the connection reliability between the insertion portions 231 and the rotating support portions 232. In addition, the insertion portions 231 and the rotating support portions 232 can be distributed sequentially along the radial direction of the transmission gear ring 23, thus avoiding interference between them.

[0081] In some embodiments, the mounting cover plate 3 is provided with two insertion mating parts 31, and the mounting cover plate 3 is also provided with a pressing part 32 located between the two insertion mating parts 31. After the insertion part 231 is inserted into the insertion mating part 31, the pressing part 32 presses against the sector gear 22. In this way, after the mounting cover plate 3 is inserted into the transmission gear ring 23, the pressing part 32 presses against the sector gear 22, which can limit the sector gear 22 from disengaging from the transmission gear ring 23, thereby ensuring more reliable rotation of the sector gear 22 and the manual worm gear 21.

[0082] Specifically, such as Figures 7-9 As shown, the outer peripheral wall of the mounting cover plate 3 is provided with two insertion mating parts 31, and the two insertion mating parts 31 are closer to the two insertion parts 231, which facilitates the insertion and mating of the two insertion mating parts 31 with the two insertion parts 231. The mounting cover plate 3 is also provided with a pressing part 32, which is located between the two insertion mating parts 31. This allows the pressing part 32 to be closer to the sector gear 22, facilitating the pressing part 32 to press the sector gear 22, so that when the manual worm gear 21 drives the sector gear 22, the sector gear 22 can move freely along the arc direction. Figure 6 The image shows the clamping part 32 clamping the sector gear 22.

[0083] Furthermore, the mounting cover 3 can be made of plastic materials such as POM, PU, ​​and PVC, which gives the clamping part 32 a certain degree of elasticity, improves the clamping effect of the clamping part 32 on the sector gear 22, and thus improves the stability of the sector gear 22 in the arc direction.

[0084] In this design, the sector gear 22 can move along an arc with the transmission gear ring 23. Specifically, one of the sector gear 22 and the transmission gear ring 23 can be provided with an arc-shaped groove, and the other can be provided with a sliding part. The sliding part can move along the arc-shaped groove in an arc-shaped trajectory. Furthermore, both the arc-shaped groove and the sliding part can be at least one. In this embodiment, for example... Figure 7 As shown, there are two arc-shaped grooves and two sliding parts, which can improve the reliability and stability of the movement of the sector gear 22 relative to the transmission gear ring 23.

[0085] Furthermore, the two insertion parts 31 and the two insertion parts 231 can form two sets of insertion structures. These two sets of insertion structures can effectively limit the movement of one set of manual worm gear 21 and sector gear 22. Since there are multiple sets of manual worm gear 21 and sector gear 22, each set of manual worm gear 21 has two sets of insertion structures. Thus, by rotating the mounting cover plate 3 once and connecting it to the transmission gear ring 23, the mounting cover plate 3 can simultaneously limit multiple sets of manual worm gear 21 and sector gear 22 through multiple sets of two-part insertion structures, improving the convenience and reliability of installation. In this embodiment, there are four sets of manual worm gear 21 and sector gear 22, evenly spaced along the circumference of the transmission gear ring 23, and each set of manual worm gear 21 and sector gear 22 is limited by two sets of insertion structures.

[0086] And in actual design, such as Figure 4 As shown, a plug-in mating part 31 on the mounting cover 3 has a first contact surface formed on the side near the manual worm gear 21. At least a portion of the first contact surface is constructed as an arc-shaped surface for tightly fitting with the manual worm gear 21, thereby improving the reliable limiting of one end of the manual worm gear 21 by the plug-in mating part 31. Figure 5 As shown, another insertion and mating part 31 of the mounting cover plate 3 has a second mating surface formed on the side near the manual worm gear 21. The second mating surface can be constructed as a plane for tightly fitting with the manual worm gear 21, thereby improving the reliable limiting of the other end of the manual worm gear 21 by the insertion and mating part 31.

[0087] In some embodiments, the transmission gear ring 23 is provided with at least one snap-fit ​​portion 234, and the mounting cover plate 3 is provided with at least one snap-fit ​​mating portion 33, wherein at least one snap-fit ​​portion 234 and at least one snap-fit ​​mating portion 33 are snap-fitted and limited.

[0088] In this way, by inserting at least one snap-fit ​​part 234 into at least one snap-fit ​​mating part 33, the mounting cover plate 3 and the transmission gear ring 23 are connected in a circumferentially limiting manner to ensure the accuracy of the mounting position of the mounting cover plate 3 relative to the transmission gear ring 23, thereby improving the limiting reliability of the mounting cover plate 3 on the manual worm gear 21, and thus improving the motion stability and reliability of the manual worm gear 21 driving the sector gear 22.

[0089] Specifically, the number of snap-fit ​​parts 234 and the number of snap-fit ​​mating parts 33 are matched. Each snap-fit ​​part 234 and snap-fit ​​mating part 33 is set to at least one. At least one snap-fit ​​part 234 and at least one snap-fit ​​mating part 33 are distributed in a one-to-one correspondence. In actual installation, the mounting cover plate 3 is rotated relative to the transmission gear ring 23. After at least one insertion part 231 and at least one insertion mating part 31 are inserted and mated in place, at the same time, at least one snap-fit ​​part 234 and at least one snap-fit ​​mating part 33 are snapped and limited, so that the mounting cover plate 3 can be installed in place relative to the transmission gear ring 23.

[0090] In this embodiment, as Figure 7 As shown, both the snap-fit ​​part 234 and the snap-fit ​​mating part 33 are provided in pairs. The two snap-fit ​​parts 234 and the snap-fit ​​mating parts 33 are engaged in a one-to-one snap-fitting manner, which can effectively limit the reverse rotation of the mounting cover plate 3 relative to the transmission gear ring 23, thereby improving the installation reliability of the mounting cover plate 3 and the transmission gear ring 23. Moreover, the snap-fit ​​part 234 and the snap-fit ​​mating part 33 can also be provided as one, three, etc.

[0091] The snap-fit ​​part 234 is constructed as a snap-fit ​​rib, which protrudes from the surface of the transmission gear ring 23. The snap-fit ​​mating part 33 is constructed as a snap fastener, which engages with the snap-fit ​​rib.

[0092] Specifically, the snap-fit ​​rib is designed to protrude from the surface of the transmission gear ring 23, making it easier for the snap-fit ​​rib to engage with the snap-fit ​​mating part 33. The snap-fit ​​mating part 33 can be constructed as a snap fastener, meaning a snap fastener can be formed on the surface of the mounting cover plate 3 near the transmission gear ring 23, facing the snap-fit ​​rib. This allows the snap fastener to be closer to the snap-fit ​​rib, facilitating reliable engagement. Furthermore, the snap-fit ​​rib can be constructed to extend radially on the surface of the transmission gear ring 23, with the snap fasteners distributed circumferentially along the mounting cover plate 3. The snap fasteners have an open side, allowing them to engage with the snap-fit ​​rib from the open side. After the snap fasteners engage with the snap-fit ​​rib, movement of the mounting cover plate 3 in the opposite direction to the engagement direction is restricted, improving the installation reliability of the mounting cover plate 3.

[0093] Furthermore, the snap-fit ​​rib can be integrally formed with the transmission gear ring 23, which can improve the connection reliability between the snap-fit ​​rib and the transmission gear ring 23. In addition, the buckle can be integrally formed with the mounting cover plate 3, which can improve the connection reliability between the buckle and the mounting cover plate 3. Thus, the buckle can improve the limiting reliability of the snap-fit ​​rib on the mounting cover plate 3.

[0094] The mounting cover 3 can be made of plastic materials such as POM, PU, ​​and PVC, which gives the buckle a certain degree of elasticity. When the buckle rotates with the mounting cover 3 in the screwing direction, the buckle can pass over the top of the snap-fit ​​rib and engage with the snap-fit ​​rib to achieve a snap-fit ​​limit, which can effectively limit the reverse movement of the mounting cover 3 and improve the reliability of the mounting cover 3.

[0095] And such as Figure 7 The diagram shows the installation steps of the mounting cover plate 3 and the transmission gear ring 23. First, bring the mounting cover plate 3 and the transmission gear ring 23 closer together along the axial direction. Then, while rotating the mounting cover plate 3 counterclockwise relative to the transmission gear ring 23, insert the insertion part 231 into the insertion mating part 31, and engage the snap-fit ​​part 234 with the snap-fit ​​part 33. This completes the connection between the mounting cover plate 3 and the transmission gear ring 23.

[0096] In some embodiments, the manual worm gear 21 includes a manual operation part 211 and a screw drive part 212. The manual operation part 211 is connected to one end of the screw drive part 212. The sector gear 22 includes a first meshing part 221. The screw drive part 212 meshes with the first meshing part 221 to drive the sector gear 22 to rotate.

[0097] Specifically, such as Figure 3 , Figures 7-9 As shown, the screw drive unit 212 is located in the middle of the manual worm gear 21, and the manual operation unit 211 is connected to one end of the screw drive unit 212. The screw drive unit 212 is used to output power to the manual worm gear 21, and the manual operation unit 211 is used for manual operation and power input. In actual use, the operator inputs driving force from one end of the screw drive unit 212 through the manual operation unit 211, and the power is transmitted to the sector gear 22 through the screw drive unit 212. The sector gear 22 includes a first meshing part 221, which is distributed close to the screw drive unit 212, allowing the screw drive unit 212 to mesh with the first meshing part 221. Through the meshing of the screw drive unit 212 and the first meshing part 221, the sector gear 22 can be driven to rotate, thereby enabling the sector gear 22 to perform a circular motion relative to the transmission gear ring 23 by manual operation.

[0098] The screw drive section 212 is equipped with meshing teeth, and the first meshing section 221 is also constructed with meshing teeth, enabling meshing and power transmission between the two. Its structure is similar to a worm gear, and it is simple to install, easy to operate, and low in cost.

[0099] In some embodiments, the sector gear 22 and / or the transmission gear ring 23 are provided with a second meshing portion 222. That is, the sector gear 22 or the transmission gear ring 23 is provided with a second meshing portion 222, and both the sector gear 22 and the transmission gear ring 23 are provided with a second meshing portion 222. Through the second meshing portion 222, the sector gear 22 and / or the transmission gear ring 23 can be connected to the transmission structure 4 for power transmission. The second meshing portion 222 is the power output end of the sector gear 22 or the transmission gear ring 23.

[0100] The transmission structure 4 includes a transmission gear shaft 41 and a rack 42. The rack 42 is rotatably connected to the moving decorative plate 11 of the reflector bowl 1. The transmission gear shaft 41 is provided with a first gear part 411 and a second gear part 412. The first gear part 411 meshes with the second meshing part 222, and the second gear part 412 meshes with the rack 42. When the sector gear 22 and / or the transmission gear ring 23 rotate, they sequentially drive the corresponding moving decorative plate 11 and reflector bowl 1 to open or close through the second meshing part 222, the transmission gear shaft 41 and the rack 42.

[0101] Specifically, such as Figure 14 As shown, the sector gear 22 and the transmission gear ring 23 are respectively connected to the reflector bowl 1 via the transmission structure 4, enabling the movement of the reflector bowl 1. The transmission structure 4 includes a transmission gear shaft 41 and a rack 42. The transmission gear shaft 41 is provided with a first gear section 411 and a second gear section 412. The first gear section 411 and the second gear section 412 are spaced apart along the axial direction of the transmission gear shaft 41. The first gear section 411 is the power input end. By engaging the first gear section 411 with the second meshing part 222, the power at the sector gear 22 or the transmission gear ring 23 can be transmitted through the second meshing part 222 to the first gear ring 22. After the first gear 411 meshes, the power is transmitted to the transmission gear shaft 41. The second gear 412 is the power output end. By meshing the second gear 412 with the rack 42, the power at the transmission gear shaft 41 can be transmitted to the rack 42 through the meshing of the second gear 412 and the rack 42, thus realizing the movement of the rack 42. The rack 42 is rotatably connected to the moving trim plate 11 of the reflector bowl 1, which allows the rack 42 to drive the moving trim plate 11 and the reflector bowl 1 to move. When the second gear 412 drives the rack 42 away from the headlight source, the rack 42 can drive the reflector bowl 1 to gradually open. The schematic diagram of its open state is shown in the figure. Figure 2 ,and Figure 13 As shown, when the second gear 412 drives the rack 42 to move closer to the headlight source, the rack 42 can drive the reflector 1 to gradually close. A schematic diagram of its closed state is shown below. Figure 12 As shown.

[0102] Among them, the sector gear 22 is used to realize the power output of the manual end. In this embodiment, for example... Figure 14As shown, there are four sets of manual worm gear 21 and sector gear 22. Each sector gear 22 is provided with a second meshing part 222. The transmission structure 4 includes four sets of transmission gear shafts 41 and racks 42. In actual use, we take one set of manual worm gear 21, sector gear 22, transmission gear shaft 41, rack 42 and reflector 1 as an example. The user can drive the manual worm gear 21 to rotate to drive the sector gear 22 to rotate. The second meshing part 222 of the sector gear 22 meshes with the first gear part 411, which can make the first gear part 411 rotate. The rotation of the first gear part 411 drives the transmission gear shaft 41 to rotate, which in turn drives the second gear part 412 to rotate. Through the meshing of the second gear part 412 with the rack 42, the rack 42 can be driven to perform linear motion, so as to drive the movement of the decorative plate 11 through the rack 42, thereby realizing the manual drive of the reflector 1.

[0103] Furthermore, the transmission gear ring 23 is used to realize the power output of the automatic end. In this embodiment, for example... Figure 14 As shown, the transmission gear ring 23 is provided with a second meshing part 222, which consists of four sets. The transmission structure 4 also includes four sets of transmission gear shafts 41 and racks 42. In actual use, the following description is based on one set of second meshing parts 222, transmission gear shafts 41, racks 42, and reflector bowl 1. When the automatic end drives the transmission gear ring 23 to rotate, the second meshing part 222 of the transmission gear ring 23 meshes with the first gear part 411, which causes the first gear part 411 to rotate. The rotation of the first gear part 411 drives the transmission gear shaft 41 to rotate, which in turn drives the second gear part 412 to rotate. Through the meshing of the second gear part 412 with the rack 42, the rack 42 can be driven to perform linear motion, thereby driving the movement of the decorative plate 11 through the rack 42, thus realizing the automatic drive of the reflector bowl 1.

[0104] Among them, such as Figure 14 As shown, the adjustment structure 2 also includes a drive member 9, which can be configured as a drive motor. The transmission gear ring 23 is provided with a drive gear section 235. The output end of the drive motor meshes with the drive gear section 235 through the drive gear section 6. In this way, the drive member 9 can drive the transmission gear ring 23 to rotate.

[0105] In this embodiment, as Figure 12 and Figure 13As shown, the reflector bowl 1 is connected to the rack 42 via the moving trim plate 11. The moving trim plate 11 can be rotatably connected to the rack 42 via a rotating shaft or hinge, and the reflector bowl 1 can also be rotatably connected to the moving trim plate 11 via a rotating shaft or hinge. The moving trim plate 11 can also be rotatably connected to the decorative frame 7 of the headlight structure 100 via a rotating shaft or hinge, and the reflector bowl 1 can also be rotatably connected to the fixed housing of the headlight structure 100 via a rotating shaft or hinge. In this way, when the rack 42 moves linearly, it can push the moving trim plate 11 to rotate open or close relative to the headlight light source, and at the same time as the moving trim plate 11 moves, it drives the reflector bowl 1 to rotate open or close relative to the headlight light source, so as to adjust the angle of the reflector bowl 1.

[0106] The transmission gear shaft 41 also includes a connecting part, which is used to rotatably connect with the inner mounting seat 5 of the vehicle lamp structure 100. That is, the inner mounting seat 5 can realize the rotational support of the transmission gear shaft 41 to ensure the rotational reliability of the transmission gear shaft 41. The transmission gear ring 23 is a common gear ring, which can realize the common adjustment of multiple reflector bowls 1 at the same time. Thus, in actual production, the driving component 9 drives the transmission gear ring 23 to move, thereby driving multiple reflector bowls 1 to move. This can realize the automatic opening or closing of the reflector bowls 1 relative to the vehicle lamp light source. It can also be realized by manually driving the sector gear 22 to move through the worm gear 21, thereby driving the reflector bowls 1 to move. This can realize the manual opening or closing of the reflector bowls 1 relative to the vehicle lamp light source, so as to achieve accurate control of the opening angle of the reflector bowls 1, thereby improving the production quality and production reliability of the vehicle lamp structure 100.

[0107] And such as Figure 10 and Figure 11 The diagram shows the installation steps of mounting cover plate 3 and transmission gear ring 23 on the decorative frame 7 of the vehicle lamp structure. First, bring the entire mounting cover plate 3 and transmission gear ring 23 close to the decorative frame 7 and align them with the decorative frame 7. Then, connect the mounting housing 8 to the decorative frame 7 to complete the installation of the vehicle lamp structure 100.

[0108] This utility model also proposes a vehicle.

[0109] The vehicle according to the embodiments of this utility model includes the headlight structure 100 of any of the above embodiments. The headlight structure 100 can specifically be the headlight structure of the vehicle, that is, the headlight structure 100 is installed in the front area of ​​the vehicle and is used to illuminate the road ahead of the vehicle when the vehicle is used at night. The headlight structure 100 includes an adjustment structure 2, a reflector 1, and a mounting cover plate 3. By setting the manual worm gear 21, the sector gear 22, the transmission gear ring 23, and the cooperation of multiple reflectors 1, the transmission gear ring 23 can automatically adjust the angle of the reflector 1, and the manual worm gear 21 can manually adjust the reflector. The angle of the reflector bowl 1 is adjusted to ensure that the light pattern and range reflected by the reflector bowl 1 better meet the set requirements, thus improving the accuracy of the angle adjustment of the reflector bowl 1. The mounting cover plate 3 is circumferentially rotated and fixed relative to the transmission gear ring 23, allowing the manual worm gear 21 to be reliably positioned between the transmission gear ring 23 and the mounting cover plate 3. This improves the reliability and stability of the motion transmission between the manual worm gear 21 and the sector gear 22, thereby enhancing the reliability of the manual worm gear 21 in adjusting the angle of the reflector bowl 1. The manual worm gear 21 is reliably fixed, and the installation of the mounting cover plate 3 is simple, reducing disassembly and maintenance costs. Furthermore, the structure is simple, the performance is good, and it is highly practical, suitable for the press-fit installation of ring-shaped structural parts.
