[0014] In some embodiments, an avoidance groove is formed on the first connecting shaft, and part of the first limiting edge is located in the avoidance groove. The avoidance groove has opposite first side wall and second side wall in the first direction. The first side wall is in contact with the first limiting edge, and the second side wall is spaced from the first limiting edge;

[0015] In the first direction, the gap between the strengthening structure and the side wall of the accommodation space is smaller than the gap between the second side wall and the first limiting edge.

[0016] In some embodiments, the mounting member further includes a body portion bent and connected to the first elastic piece, and a second elastic piece connected to the body portion. The body portion is connected to the housing.

[0039] In the drawings, the same components are denoted by the same reference numerals. The drawings are not drawn to actual scale. Detailed implementation manners

[0040] The features and exemplary embodiments of various aspects of the present application will be described in detail below. To make the objectives, technical solutions, and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without some of these specific details. The following description of the embodiments is only intended to provide a better understanding of the present application by showing examples of the present application.

[0041] It should be noted that in this document, relational terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, such that a process, method, article or device comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or device. Without further limitation, elements defined by the statement "comprising..." do not exclude the presence of additional identical elements in the process, method, article or device comprising the said elements.

[0042] A head-up display (HUD) device is usually installed at the top of the instrument panel in front of the vehicle driver or near the bottom of the windshield. The head-up display device can project important information of the vehicle (such as vehicle speed, navigation instructions, etc.) within the driver's forward field of vision, so that the driver does not need to look down at the instrument significantly, thereby reducing the line of sight transfer and improving driving safety and convenience.

[0043] However, during vehicle driving, the vehicle body will inevitably shake. When the vehicle body shakes, it will drive the head-up display device to shake, and then cause the mirror body to shake, resulting in damage to the mirror body or a certain degree of collision noise. Therefore, it is necessary to improve the connection accuracy of the mirror body in the head-up display device and reduce the shaking amplitude of the mirror body.

[0044] In view of this, in a first aspect, please refer to Figures 1 to 4The embodiment of the present application provides a head-up display device, which includes a housing 10, a mirror assembly 20 and a mounting member 30. The housing 10 includes a first mounting groove 11 having preset spaces on both sides along a first direction X, and a first limiting rib 12 is arranged inside the first mounting groove 11. The mirror assembly 20 includes a mirror body 21 and a first connecting shaft 22 connected to one end of the mirror body 21 along the first direction X, and at least part of the first connecting shaft 22 is located inside the first mounting groove 11. The mounting member 30 is connected to the housing 10, and the mounting member 30 includes a first elastic piece 31 extending to one end of the first connecting shaft 22 away from the mirror body 21 along the first direction X. The first connecting shaft 22 includes a first portion 221 located between the first elastic piece 31 and the first limiting rib 12 along the first direction X, and the first elastic piece 31 contacts the first portion 221 to generate a force so that the first portion 221 abuts against the first limiting rib 12 in the first direction X.

[0045] The head-up display device provided in the embodiment of the present application can be applied to vehicles to display important information of the vehicle in the field of vision in front of the driver by projection. Alternatively, the head-up display device provided in the embodiment of the present application can also be applied to the aviation field and installed in the cockpit of an aircraft to provide the pilot with an intuitive display of key flight information. Alternatively, the head-up display device provided in the embodiment of the present application can also be applied to the bridge of a ship to display navigation-related data.

[0046] The head-up display device provided in the embodiment of the present application includes a housing 10, a mirror assembly 20 and a mounting member 30. Among them, the housing 10 serves as the frame structure of the head-up display device. On the one hand, it provides a mounting base for the remaining structures. On the other hand, the head-up display device can be connected and installed on other structures through the housing 10. The mirror assembly 20 is used to reflect and project relevant information, and adjust the projection angle of the relevant information according to actual needs. It can be understood that the mirror assembly 20 should have the freedom to rotate relative to the housing 10 to achieve the adjustment of the projection angle of the relevant information. The mounting member 30 is used to connect the mirror assembly 20 to the housing 10 to ensure the relative stability of the position of the mirror assembly 20 on the housing 10.

[0047] Specifically, the housing 10 includes a first mounting groove 11 having preset spaces on both sides along the first direction X, and the mirror body assembly 20 includes a mirror body 21 and a first connecting shaft 22 connected to one end of the mirror body 21 along the first direction X, and at least a portion of the first connecting shaft 22 is located inside the first mounting groove 11. The first connecting shaft 22 is arranged to protrude from the mirror body 21 in the first direction X, and the first connecting shaft 22 can enter the first mounting groove 11 from one side of the first mounting groove 11 in the first direction X, and the effect of limiting the positional relationship between the mirror body 21 and the housing 10 is achieved by limiting the positional relationship of the first connecting shaft 22 inside the first mounting groove 11.

[0048] Further, a first limiting rib 12 is provided inside the first mounting groove 11, and the first limiting rib 12 protrudes from the groove side wall of the first mounting groove 11. When the first connecting shaft 22 is inside the first mounting groove 11, the first connecting shaft 22 can contact the first limiting rib 12. It can be understood that, based on the fact that the first mounting groove 11 has a preset space on both sides of the first direction X, when the first limiting rib 12 is provided inside the first mounting groove 11, the first limiting rib 12 is within the size range of the first mounting groove 11 in the first direction X, and when the first connecting shaft 22 contacts the first limiting rib 12 in the first direction X, the first limiting rib 12 can limit the sliding of the first connecting shaft 22 to one side along the first direction X.

[0049] The mounting member 30 is first connected to the housing 10 to fix the position of the mounting member 30. The mounting member 30 includes a first elastic piece 31 extending to the end of the first connecting shaft 22 away from the mirror body 21 along the first direction X. The first elastic piece 31 can contact the first connecting shaft 22, so that the first connecting shaft 22 has a movement trend away from the first elastic piece 31. Further, the first elastic piece 31 contacts the end surface of the first connecting shaft 22 away from the mirror body 21 in the first direction X, which can form a stable contact between the first elastic piece 31 and the first connecting shaft 22, thereby reducing the probability of the first elastic piece 31 and the first connecting shaft 22 being dislocated and separated.

[0050] The first connecting shaft 22 includes a first portion 221 located between the first elastic sheet 31 and the first limiting edge 12 along the first direction X. It can be understood that the first portion 221 has an area in contact with the first limiting edge 12 and an area in contact with the first elastic sheet 31. When the first elastic sheet 31 contacts the first portion 221, a corresponding force can be generated to abut the first portion 221 against the first limiting edge 12 in the first direction X. Due to the restriction of the first limiting edge 12 and the first elastic sheet 31 on the first portion 221 in the first direction X, the position of the first portion 221 inside the first mounting groove 11 will be fixed, thereby fixing the position of the first connecting shaft 22 inside the first mounting groove 11, thereby ensuring the relative position accuracy between the mirror body 21 and the housing 10, and reducing the probability of shaking between the mirror body 21 and the housing 10.

[0051] In summary, in the embodiment of the present application, the mirror body 21 is connected to the housing 10 by connecting the first connecting shaft 22 inside the first mounting groove 11, and the positioning between the mirror body 21 and the housing 10 is ensured by positioning the first connecting shaft 22 in the first mounting groove 11. Specifically, the first portion 221 on the first connecting shaft 22 directly contacts the first elastic piece 31, and the first portion 221 is pressed against the first limiting edge 12 by the elastic force of the first elastic piece 31, so as to fix the position of the first connecting shaft 22 inside the first mounting groove 11. With the structure provided by the present application, only the first portion 221 exists between the first elastic piece 31 and the first limiting edge 12. This is equivalent to the elastic force generated by the first elastic piece 31 directly acting on the first portion 221 without passing through other structural components, which can better control the elastic force when the first elastic piece 31 undergoes elastic deformation and ensure the stability of the elastic force. At the same time, under the action of the first elastic piece 31, the first portion 221 abuts against the first limiting edge 12, and corresponding acting forces can be generated at the abutting position between the two. This is equivalent to that when manufacturing the first connecting shaft 22, controlling the dimension of the first portion 221 in the first direction X can correspondingly realize the positioning of the first connecting shaft 22 inside the first mounting groove 11. Only by controlling the distance between the elastic force action point of the first elastic piece 31 and the acting force point generated by the abutment of the first limiting edge 12, the production difficulty of the first connecting shaft 22 can be reduced according to the above structure, which is beneficial to improving the machining accuracy and assembly accuracy of the first connecting shaft 22, thereby improving the connection accuracy between the mirror body 21 and the housing 10 and reducing the shaking amplitude of the mirror body 21 relative to the housing 10.

[0052] In some embodiments, the first connecting shaft 22 includes a second portion 222 connected to the first portion 221 and located on the side of the first portion 221 facing the mirror body 21. The second portion 222 is recessed inward on its circumferential surface to form an avoidance groove 223, and a part of the first limiting edge 12 is located in the avoidance groove 223. The avoidance groove 223 has opposite first side wall and second side wall in the first direction X. Under the action of the first elastic piece 31, the first side wall is in abutting contact with the first limiting edge 12, and the second side wall is spaced from the first limiting edge 12.

[0053] The first connecting shaft 22 includes a first part 221 and a second part 222. The first part 221 is located between the first elastic piece 31 and the first limiting edge 12, and the second part 222 is located between the first part 221 and the mirror body 21. An avoidance groove 223 is formed by inward depression on the axial surface of the second part 222. When the first connecting shaft 22 is inside the first installation groove 11, part of the first limiting edge 12 is inside the avoidance groove 223. By setting the form of the avoidance groove 223, the first limiting edge 12 can be accommodated. After the first limiting edge 12 is inside the avoidance groove 223, through the mutual abutment between the two side walls of the first limiting edge 12 in the first direction X and the two side walls of the avoidance groove 223 in the first direction X, the moving distance of the first connecting shaft 22 in the first direction X can be reduced, and the impact and damage of the first connecting shaft 22 on the first elastic piece 31 can be reduced.

[0054] In the embodiment of the present application, it is inevitable that the mirror body assembly 20 shakes. Considering the protection of the mirror body 21, the size of the avoidance groove 223 in the first direction X is larger than the size of the first limiting edge 12 in the first direction X. That is to say, when the first limiting edge 12 is inside the avoidance groove 223, the two side walls of the first limiting edge 12 in the first direction X and the two side walls of the avoidance groove 223 in the first direction X do not come into contact simultaneously, so as to allow the first connecting shaft 22 to shake to a certain extent inside the first installation groove 11, avoid rigid positioning between the mirror bodies, and thus play a certain protective role on the mirror body 21.

[0055] Specifically, the avoidance groove 223 has an opposite first side wall and a second side wall in the first direction X. Under the action of the first elastic piece 31, the first side wall abuts against the first limiting edge 12, and the second side wall is spaced from the first limiting edge 12. When the mirror body 21 shakes, the first connecting shaft 22 may slide a certain distance along the first direction X against the elastic force of the first elastic piece 31. At this time, the first side wall and the first limiting edge 12 move away from each other, and the second side wall and the first limiting edge 12 move closer to each other. Under the elastic force of the first elastic piece 31, the first connecting shaft 22 still has a tendency to press the first side wall against the first limiting edge 12. When the mirror body 21 shakes to the maximum extent, the second side wall abuts against the first limiting edge 12, and the first side wall is spaced from the first limiting edge 12. The abutment between the second side wall and the first limiting edge 12 can limit the maximum shake of the first connecting shaft 22 inside the first installation groove 11 and avoid the impact of the first connecting shaft 22 on the first elastic piece 31. At the same time, during the shaking process of the first connecting shaft 22, there is still the elastic force of the first elastic piece 31, which can slow down the shaking degree of the first connecting shaft 22 and effectively protect the mirror body 21.

[0056] In some embodiments, the first connecting shaft 22 includes a second portion 222 connected to the first portion 221 and located on the side of the first portion 221 facing the mirror body 21. The second portion 222 is provided with a second limiting edge protruding outward on its circumferential surface. In the first direction X, the second limiting edge is on the side of the first limiting edge 12 away from the first elastic piece 31. Under the action of the first elastic piece 31, the first limiting edge 12 and the second limiting edge are in contact with each other.

[0057] In some embodiments, the housing 10 encloses to form a receiving space 13 for receiving the mirror body 21. The first mounting groove 11 is located on the housing 10 and is communicated with the receiving space 13. The head-up display device further includes a strengthening structure 40. The first connecting shaft 22 is connected to the mirror body 21 through the strengthening structure 40. The strengthening structure 40 is at least partially located inside the receiving space 13. In the first direction X, the strengthening structure 40 is spaced apart from the side wall of the receiving space 13.

[0058] In the art, generally, the size of the mirror body 21 is larger than that of the first connecting shaft 22. In the embodiments of the present application, to ensure the positional stability between the mirror body 21 and the housing 10, it is necessary to ensure the positional stability of the first connecting shaft 22 inside the first mounting groove 11, and at the same time, it is necessary to ensure the connection strength between the first connecting shaft 22 and the mirror body 21. In view of this, the head-up display device provided in the embodiments of the present application may further include a strengthening structure 40. The first connecting shaft 22 is connected to the mirror body 21 through the strengthening structure 40.

[0059] At the same time, in order to prevent the mirror body 21 from being damaged by the housing 10 during shaking, the housing 10 is provided with a receiving space 13 for receiving the mirror body 21. The first mounting groove 11 is located on the housing 10 and is communicated with the receiving space 13. The strengthening structure 40 is at least partially located inside the receiving space 13. The mirror body 21 is enclosed and received by the receiving space 13 to further protect the mirror body 21.

[0060] Furthermore, in order not to affect the movement of the mirror body 21 by the strengthening structure 40 and to prevent the strengthening structure 40 from forming a rigid positioning for the mirror body 21, in the first direction X, the strengthening structure 40 is spaced apart from the side wall of the receiving space 13. It can be understood that under the action of the first elastic piece 31, the first side wall is in contact with the first limiting edge 12, and the strengthening structure 40 is spaced apart from the side wall of the receiving space 13, so as to ensure the shaking space of the mirror body 21 in the first direction X.

[0061] In some embodiments, considering that multiple impacts of the first connecting shaft 22 on the first limiting edge 12 may affect the strength of the first limiting edge 12, for the protection of the first limiting edge 12, in the first direction X, the gap between the reinforcing structure 40 and the side wall of the accommodating space 13 is smaller than the gap between the second side wall and the first limiting edge 12. Through the above arrangement, under the action of the first elastic sheet 31, the first side wall and the first limiting edge 12 are contacted and positioned; during the shaking process of the mirror body 21 and the first connecting shaft 22, the reinforcing structure 40 shakes together, and since the gap between the reinforcing structure 40 and the side wall of the accommodating space 13 is smaller than the gap between the second side wall and the first limiting edge 12, the reinforcing structure 40 will first contact the side wall of the accommodating space 13 to form a limit, so as to avoid contact between the second side wall and the first limiting edge 12, thereby avoiding multiple impacts of the first connecting shaft 22 on the first limiting edge 12 and improving the service life of the first limiting edge 12.

[0062] In some embodiments, the shell 10 also includes a second mounting groove 14 having preset spaces on both sides along the first direction X, and the second mounting groove 14 is arranged opposite to the first mounting groove 11 in the first direction X. The mirror body assembly 20 also includes a second connecting axis 23 connected to the side of the mirror body 21 away from the first connecting axis 22 along the first direction X, and at least a portion of the second connecting axis 23 is located inside the second mounting groove 14.

[0063] Considering that the mirror body 21 generally has a longer dimension in the first direction X, and considering that the connection between the mirror body 21 and the housing 10 is stable, the housing 10 further includes a second mounting groove 14, which is arranged opposite to the first mounting groove 11 in the first direction X. Correspondingly, a second connecting shaft 23 is further connected to the mirror body 21, which is arranged opposite to the first connecting shaft 22 in the first direction X, and at least a portion of the second connecting shaft 23 is located inside the second mounting groove 14.

[0064] In the connection and cooperation between the second connecting shaft 23 and the second mounting groove 14, the same connection and cooperation structure as that between the first connecting shaft 22 and the first mounting groove 11 can be provided to ensure the connection and cooperation between the second connecting shaft 23 and the second mounting groove 14. It is also possible not to provide a corresponding structure, and it is only necessary to ensure that the second connecting shaft 23 and the second mounting groove 14 can have a movable distance in the first direction X.

[0065] In some embodiments, see Figures 1 to 5, the mounting member 30 includes a body portion 32 bent and connected to the first elastic piece 31, and a second elastic piece 33 connected to the body portion 32. The body portion 32 is connected to the housing 10. The body portion 32 and the first limiting edge 12 are disposed on both sides of the first connecting shaft 22 along the second direction Y, and the first direction X intersects with the second direction Y. The second elastic piece 33 is located on the side of the first connecting shaft 22 away from the first limiting edge 12, and the second elastic piece 33 is in contact with the first connecting shaft 22.

[0066] In the embodiment of the present application, considering that the directions of the mirror body 21 and the first connecting shaft 22 are not easy to control during the shaking process, elastic limiting is also formed in the second direction Y of the mirror body 21, and the second direction Y intersects with the first direction X.

[0067] Specifically, the mounting member 30 includes a body portion 32 bent and connected to the first elastic piece 31, and a second elastic piece 33 connected to the body portion 32. Among them, the body portion 32 is connected to the housing 10. The first elastic piece 31 restricts the movement of the first connecting shaft 22 in the first direction X, and the second elastic piece 33 restricts the movement of the first connecting shaft 22 in the second direction Y. In order to enable the mounting member 30 to limit the first connecting shaft 22 well in both the first direction X and the second direction Y, the body portion 32 and the first limiting edge 12 are disposed on both sides of the first connecting shaft 22. The second elastic piece 33 and the body portion 32 are on the same side of the first connecting shaft 22, and the second elastic piece 33 is in contact with the first connecting shaft 22.

[0068] In order to facilitate connecting the mounting member 30 to the housing 10 and also to facilitate installing the first connecting shaft 22 into the first mounting groove 11, the first mounting groove 11 is also provided with an opening on one side in the second direction Y. When the body portion 32 is connected to the housing 10, the body portion 32 can close the opening. At the same time, a part of the second elastic piece 33 can extend into the first mounting groove 11 and contact the first connecting shaft 22 located inside the first mounting groove 11.

[0069] In some embodiments, the housing 10 is provided with screws on both sides of the opening, and connection holes are provided on the body portion 32. The screws can be located inside the connection holes, and then the connection nuts are connected to the screws to realize the connection between the body portion 32 and the housing 10. Alternatively, guiding columns can also be provided on the housing 10. Correspondingly, guiding holes are provided on the body portion 32. After the guiding holes and the guiding columns form a preliminary positioning of the body portion 32 and the housing 10, the body portion 32 is fixed by the connection nuts.

[0070] In some embodiments, please refer to Figures 1 to 6, a limiting groove 224 is formed by inward depression on the circumferential surface of the first connecting shaft 22, and part of the second elastic piece 33 is located inside the limiting groove 224 and abuts against the bottom wall of the limiting groove 224. The limiting groove 224 and the avoidance groove 223 are arranged along the same circumferential trajectory on the circumferential side of the first connecting shaft 22, and the dimension of the limiting groove 224 in the first direction X is not less than the dimension of the avoidance groove 223 in the first direction X.

[0071] In order to prevent the second elastic piece 33 from shifting during the contact with the first connecting shaft 22, a limiting groove 224 is formed by inward depression on the circumferential surface of the first connecting shaft 22. Part of the second elastic piece 33 is located inside the limiting groove 224 and abuts against the bottom wall of the limiting groove 224. Due to the arrangement of the limiting groove 224, the second elastic piece 33 can be restricted inside the limiting groove 224.

[0072] Meanwhile, considering the possible shaking of the first connecting shaft 22 in the first direction X, the dimension of the second elastic piece 33 in the first direction X is smaller than the dimension of the limiting groove 224 in the first direction X. That is to say, when the second elastic piece 33 is located inside the limiting groove 224, the two sides of the second elastic piece 33 in the first direction X do not directly contact the two side walls of the limiting groove 224 in the first direction X, so that the first connecting shaft 22 can slide in the first direction X on the premise that the position of the second elastic piece 33 is fixed.

[0073] In the second direction Y, corresponding acting forces are applied to both sides of the first connecting shaft 22 by the first limiting edge 12 and the second elastic piece 33 respectively. The avoidance groove 223 corresponding to the first limiting edge 12 and the limiting groove 224 corresponding to the second elastic piece 33 are respectively arranged on the first connecting shaft 22. In order to prevent the first limiting edge 12 and the second elastic piece 33 from generating torque on the first connecting shaft 22, the limiting groove 224 and the avoidance groove 223 are arranged along the same circumferential trajectory on the circumferential side of the first connecting shaft 22, so that the acting forces of the second elastic piece 33 and the first limiting edge 12 on the first connecting shaft 22 are as much as possible in the same vertical plane, reducing the torque generated by the offset of the acting forces of the first limiting edge 12 and the second elastic piece 33 on the first connecting shaft 22.

[0074] During the application of the head-up display device, in order to ensure the smooth rotation of the mirror body 21, it is necessary to ensure the smooth rotation of the first connecting shaft 22 inside the first installation groove 11. The dimension of the limiting groove 224 in the first direction X is set to be not less than the dimension of the avoidance groove 223 in the first direction X. When the avoidance groove 223 can accommodate the first limiting edge 12, the limiting groove 224 can also accommodate the first limiting edge 12, thus ensuring that the first limiting edge 12 can smoothly enter the limiting groove 224 from inside the avoidance groove 223 and ensuring the smooth rotation of the first connecting shaft 22 inside the first installation groove 11.

[0075] In some embodiments, the first elastic piece 31 includes an extension portion 311 and a folded-back portion 312 that are connected to each other. The extension portion 311 is connected to the body portion 32 and extends along the first direction X. The folded-back portion 312 is inclined with respect to the extension portion 311. The projection of the folded-back portion 312 along the first direction X overlaps with a part of the projection of the extension portion 311 along the first direction X. One end of the folded-back portion 312 that is far from the extension portion 311 abuts against the first connecting shaft 22.

[0076] The elastic force in the first elastic piece 31 is adjusted by the inclination angle between the extension portion 311 and the folded-back portion 312. The extension portion 311 extends along the first direction X to the outside of the body portion 32, and then is bent by the folded-back portion 312. The elastic force of the first elastic piece 31 is adjusted by the degree of bending of the folded-back portion 312.

[0077] Furthermore, considering that after determining the inclination angle between the extension portion 311 and the bent portion after determining the required elastic force of the first elastic piece 31 and completing the production, the elastic force of the first elastic piece 31 will gradually decrease during the actual process. In order to be able to adjust and increase the elastic force of the first elastic piece 31, the first elastic piece 31 further includes an adjustment portion 313 that is bent and connected to the folded-back portion 312. The adjustment portion 313 is connected to the end of the bent portion that is far from the extension. The projection of the adjustment portion 313 along the second direction Y overlaps with a part of the projection of the folded-back portion 312 along the second direction Y. By providing some fixing structures on the adjustment portion 313 along the first direction X away from the folded-back portion 312, the elastic force of the adjustment portion 313 on the folded-back portion 312 can be adjusted, thereby increasing the elastic force of the first elastic piece 31 on the first connecting shaft 22.

[0078] In some embodiments, there is line contact positioning between the groove side wall of the first installation groove 11 and the circumferential surface of the first connecting shaft 22 in the circumferential first direction X.

[0079] In order to reduce the frictional force of the first connecting shaft 22 rotating inside the first installation groove 11, the circumferential side wall of the first connecting shaft 22 does not completely contact the groove side wall of the first installation groove 11. Only partial positions between the groove side wall of the first installation groove 11 and the circumferential surface of the first connecting shaft 22 form line contact positioning in the circumferential first direction X. In one embodiment, the line contact with the first connecting shaft 22 can be formed by setting the curvature of the groove side wall of the first installation groove 11 at different positions. In another embodiment, the line contact with the first connecting shaft 22 can be formed by setting the curvature of the groove side wall of the first limiting edge 12 at different positions.

[0080] In some embodiments, the mirror body 21 is integrally provided. The mirror body 21 is an integral structure and is directly connected to the housing 10 through the strengthening structure 40 and the first connecting shaft 22 or the second connecting shaft 23.
