[0041] The embodiments of the present invention will be described in detail below. The embodiments described with reference to the drawings are exemplary. The embodiments of the present invention will be described in detail below.

[0042] Below, with reference to Figures 1 - 11 The lens assembly of the head-up display device according to an embodiment of the present invention will be described. Further, the present invention also provides a head-up display device 100. Further, the present invention also provides a vehicle.

[0043] With reference to Figures 1 - 4 and Figures 10 - 11 As shown, the lens assembly of the head-up display device according to the embodiment of the present invention includes: a mirror 10 and a buffer assembly 20.

[0044] The mirror 10 is provided with a rotating shaft 11 on at least one side in the first direction. The first direction may be the left-right direction of the mirror 10, that is, the rotating shaft 11 is provided on at least one side of the left or right side of the mirror 10. The mirror 10 rotates about the rotating shaft 11 as the axis to adjust the angle of the mirror 10 so that the image can be presented at the desired position. With reference toFigure 2 As shown, in this embodiment, rotating shafts 11 are provided on both the left and right sides of the mirror 10. The mirror 10 with two rotating shafts 11 can be adjusted in multiple directions, having a wider viewing angle adjustment ability, which is convenient for the driver to find the best field of view. Moreover, the rotating shafts 11 on both sides can help balance the mirror 10, reduce the viewing angle deviation caused by vibration or external impact, and improve driving safety.

[0045] In some embodiments, the rotating shaft 11 is provided on the left or right side of the mirror 10. The rotating shaft 11 provided on one side simplifies the design and manufacturing process of the mirror 10, uses fewer components and materials, can reduce the overall weight of the vehicle, lower costs, and at the same time reduce the possibility of failures.

[0046] The buffer assembly 20 is provided on at least one side of the mirror 10 in the first direction, that is, the buffer assembly 20 is provided on at least one of the left or right sides of the emitting mirror, and the buffer assembly 20 and the rotating shaft 11 are provided on the same side. The buffer assembly 20 is used to prevent the mirror 10 from shaking and solve the problem of picture shaking. Refer to Figures 1 - 2 As shown, in this embodiment, there are two buffer assemblies 20, and the two buffer assemblies 20 are respectively provided on the left and right sides of the mirror 10. In some embodiments, the buffer assembly 20 can be one, and the buffer assembly 20 is provided on the same side as the rotating shaft 11.

[0047] The buffer assembly 20 includes: an adapter 21, a damper 22, and a mounting bracket 23. One end of the adapter 21 in the first direction is fixedly connected to the rotating shaft 11, and the damper 22 is fixedly connected to the other end of the adapter 21 in the first direction. By fixedly connecting one end of the adapter 21 to the rotating shaft 11 and the other end to the damper 22, the damper can be connected to the rotating shaft 11. The damper is in the form of a silicone oil hydraulic buffer, and the damper 22 is in the form of a relative leaf spring, with a more stable frictional torque. After a certain number of durability tests, for example, after 30,000 durability tests, the torque attenuation of the damper 22 is stable, which can effectively reduce the shaking of the mirror 10, solve the problem of picture shaking seen by the driver, and improve driving safety.

[0048] Moreover, the forming method of the adapter 21 adopts powder metallurgy, which avoids the fracture of the rotating shaft 11 caused by tests such as mechanical shock and mechanical vibration, and the quality of the adapter 21 is better. Further, by connecting the damper 22 through the adapter 21, the rotating shaft 11 does not need to be changed to adapt to the existing standard products of the damper 22, while reducing the mold customization cost and mold customization cycle of the damper 22.

[0049] One end of the mounting bracket 23 facing the damper 22 is provided with a first mounting hole 231, and at least a part of the damper 22 is mounted in the first mounting hole 231 to fixedly connect the damper 22 and the mounting bracket 23. The damper 22 and the first mounting hole 231 are in interference fit, and the connection is tighter to reduce the shaking of the mirror 10.

[0050] Thus, adding the damper 22 at the rotating shaft 11 of the mirror 10 can effectively prevent the mirror 10 from shaking, solve the problem of picture shaking, and improve driving safety.

[0051] Furthermore, the damper 22 and the adapter 21 are in interference fit, which can improve the tightness of the connection between the damper 22 and the adapter 21, further reduce the shaking between the damper 22 and the adapter 21, and thus reduce the shaking of the mirror 10.

[0052] At least a part of the damper 22 is mounted in the first mounting hole 231 by interference fit. That is to say, in some embodiments, the damper 22 is mounted in the first mounting hole 231 and the whole damper 22 is in interference fit with the first mounting hole 231. In this way, the connection between the damper 22 and the first mounting hole 231 will be more firm. Since the whole damper 22 is in an interference state, it can prevent the damper 22 from loosening due to vibration to the greatest extent, and further prevent the mirror 10 from shaking.

[0053] In some other embodiments, the damper 22 is mounted in the first mounting hole 231, and only part of it is in interference fit with the first mounting hole 231. Through partial interference fit, it can also ensure that the damper 22 is firmly fixed in the first mounting hole 231 and is not easy to loosen. When only part of the damper 22 adopts interference fit, the remaining part can adopt sliding or other fitting methods to avoid deformation or damage of the whole structure due to excessive stress concentration, extend the service life of the damper 22, and make it easier to disassemble when the damper 22 needs to be replaced or repaired.

[0054] Refer to Figures 5 - 8 As shown, one end of the adapter 21 facing the damper 22 is provided with a mating post 211, and one end of the damper 22 facing the adapter 21 is provided with a mating hole 221. The mating post 211 is fitted in the mating hole 221. Specifically, a mating hole 221 is provided at the middle position of the damper 22 facing the adapter 21, and a mating post is provided at the middle position of the adapter 21 facing the damper 22. The damper 22 and the adapter 21 are fixed together through the mating hole 221 and the mating post 211. Moreover, the mating post 211 and the mating hole 221 are in interference fit, and the connection between the damper and the adapter 21 is closer, avoiding shaking between the damper and the adapter 21.

[0055] Refer to Figures 5 - 8As shown, one end of the adapter 21 facing the damper 22 is provided with a first limiting portion 212. The fitting post 211 and the first limiting portion 212 are arranged at intervals. One end of the damper 22 facing the adapter 21 is provided with a second limiting portion 222. The fitting hole 221 and the second limiting portion 222 are arranged at intervals. The first limiting portion 212 and the second limiting portion 222 are in limiting cooperation. Specifically, the first limiting portion 212 can be grooves arranged at intervals on both sides of the fitting post 211, and the second limiting portion 222 can be protrusions arranged at intervals on both sides of the fitting hole 221. By fitting the protrusions into the grooves, the relative positions of the damper 22 and the adapter 21 can be restricted, and the firmness of the connection between the damper 22 and the adapter 21 can be further strengthened to reduce shaking. When the damper 22 rotates, the second limiting portion 222 can drive the first limiting portion 212 of the adapter 21 to rotate, so that the adapter 21 rotates around the axis of the rotating shaft 11, realizing the function of adjusting the angle of the emission mirror.

[0056] Referring to Figures 5 - 6 and Figures 10 - 11 As shown, a third limiting portion 232 is provided on the inner wall of the first mounting hole 231, and a fourth limiting portion 223 is provided on the outer wall of the damper 22. The third limiting portion 232 and the fourth limiting portion 223 are in limiting cooperation. Specifically, the third limiting portion 232 on the inner wall of the first mounting hole 231 can be a groove. The third limiting portion 232 is arranged on the inner wall of the first mounting hole 231 and penetrates through the first mounting hole 231. The fourth limiting portion 223 can be a protrusion on the outer wall of the damper 22. By fitting the protrusion into the groove, the position of the damper 22 installed in the first mounting hole 231 can be fixed, preventing the damper 22 from rotating in the first mounting hole 231 and improving the stability of the lens assembly of the head-up display device.

[0057] In addition, a plurality of limiting members 234 are further provided at one end of the first mounting hole 231. The plurality of limiting members 234 are evenly distributed in the circumferential direction of the first mounting hole 231. After the damper 22 is installed in the first mounting hole 231, it abuts against the limiting members 234. The limiting members 234 can limit the installation position of the damper in the first mounting hole 231 and fix the damper in the mounting bracket 23.

[0058] Referring to Figures 10 - 11 As shown, a plurality of limiting ribs 233 are arranged at intervals on the inner wall of the first mounting hole 231. The limiting ribs 233 and the damper 22 are in interference fit. The plurality of limiting ribs 233 are evenly distributed on the inner wall of the first mounting hole 231, which can increase the friction force of the inner wall of the first mounting hole 231. The limiting ribs 233 further fix the connection degree between the damper 22 and the first mounting hole 231 to reduce the shaking of the damper 22, and further reduce the shaking of the reflecting mirror 10.

[0059] Referring to Figure 9As shown, a second mounting hole 213 is provided on the adapter 21. The rotating shaft 11 is fitted in the second mounting hole 213, and the rotating shaft 11 and the second mounting hole 213 are in limit fit in the circumferential direction. After the rotating shaft 11 and the second mounting hole 213 are limited in the circumferential direction, when the second limiting portion 222 of the damper 22 drives the adapter 21 to rotate, the adapter 21 can drive the rotating shaft 11 to rotate synchronously, thereby adjusting the position of the mirror 10.

[0060] Specifically, the second mounting hole 213 is not a circular hole. Straight sections are provided at the upper and lower ends of the second mounting hole 213. Similarly, the rotating shaft 11 is a non-rotary body, and straight sections corresponding to the position of the second mounting hole 213 are also provided on the rotating shaft 11. In this way, the rotating shaft 11 cannot rotate in the second mounting hole 213, and limit fit in the circumferential direction between the rotating shaft 11 and the second mounting hole 213 can be achieved.

[0061] Referring to Figure 3 As shown, a rotating shaft 11 is provided on one side of the mirror 10 in the first direction, and the buffer assembly 20 is provided on one side of the mirror 10 in the first direction. The rotating shaft 11 and the buffer assembly 20 cooperate with each other. Or, referring to Figure 2 and Figure 4 As shown, rotating shafts 11 are provided on both sides of the mirror 10 in the first direction. There are two buffer assemblies 20, which are respectively provided on both sides of the mirror 10 in the first direction. The two rotating shafts 11 and the two buffer assemblies 20 cooperate with each other respectively.

[0062] That is to say, the mirror 10 can be provided with a first rotating shaft 11 or two rotating shafts 11. The rotating shaft 11 can be provided on the left side, the right side or both sides of the mirror 10. The buffer assembly 20 corresponds to the position of the rotating shaft 11. When the rotating shaft 11 is provided on the left side or the right side, the buffer assembly 20 is also provided on the left side or the right side to cooperate with the rotating shaft 11, reduce the shaking of the mirror 10, and improve the stability of the picture seen by the driver.
