[0010] Optionally, a rib is provided on the side of the rotating shaft facing the groove at one end corresponding to the second mounting part, and an annular limiting groove is provided in the groove corresponding to the rib. The width of the rib is equal to the width of the annular limiting groove, and the length of the rib is less than the length of the annular limiting groove, so that the rib can be locked in the annular limiting groove. The width direction is the extension direction of the rotating shaft, and the length direction is perpendicular to the width direction.
[0011] Optionally, the second elastic arm includes a first sub-elastic arm and a second sub-elastic arm separated by an opening. The first sub-elastic arm is attached to the outer wall of the rotating shaft. The second sub-elastic arm includes a body and an extension arm connected to each other. The body is attached to the outer arm of the rotating shaft, and the extension arm is located at the end of the body and extends toward the side opposite to the groove.

[0016] The beneficial effects of this utility model include:
[0017] This application provides a reflector bracket, including a housing and a rotating shaft disposed within the housing. The rotating shaft supports the reflector of a head-up display. The housing includes a first mounting member and a second mounting member disposed opposite to each other. The first mounting member has a lateral shaft hole, and a first elastic arm protrudes from one end of the lateral shaft hole away from the second mounting member. The middle portion of the first elastic arm has a through hole disposed along the extension direction of the rotating shaft, and the through hole communicates with the lateral shaft hole. The first elastic arm provides an elastic compensation structure to eliminate assembly gaps, and provides a possibility to solve the problems of movement, vibration, and abnormal noise caused by wear after rigid structure in traditional installation methods. At the same time, the lateral shaft hole allows the rotating shaft to be assembled at an inclined angle, eliminating the need for additional fasteners for fixation as in traditional installation methods.

The second mounting component has a groove, with an arc-shaped second elastic arm at the top of the groove. The second elastic arm and the groove enclose a receiving portion that fits the outer wall of the rotating shaft. The arc-shaped second elastic arm can use its elasticity to make an interference fit with the outer wall of the rotating shaft, limiting the rotating shaft and eliminating clearance in that direction. On the other hand, the arc design facilitates the installation of the rotating shaft and acts as a guide. During the rotating shaft's rotation, elastic compensation can maintain a stable fit, further preventing vibration and abnormal noise caused by increased clearance in the shaft hole due to wear. One end of the rotating shaft passes through a lateral shaft hole and a through hole of the first elastic arm, while the other end is located in the receiving portion. The above-mentioned reflector bracket facilitates installation, improves the rotation accuracy and stability of the reflector, and reduces the possibility of reflector vibration or abnormal noise.

[0029] Please refer to Figure 1One aspect of this application provides a reflector bracket, including a housing 110 and a rotating shaft 120 disposed within the housing 110. The rotating shaft 120 is used to support a reflector 210 of a head-up display. The housing 110 includes a first mounting member 111 and a second mounting member 112 disposed opposite to each other. The first mounting member 111 has a lateral shaft hole, and a first elastic arm 113 protrudes from one end of the lateral shaft hole away from the second mounting member 112. The middle part of the first elastic arm 113 has a through hole disposed along the extension direction of the rotating shaft 120, and the through hole communicates with the lateral shaft hole. The second mounting member 112 has a groove, and an arc-shaped second elastic arm 114 is disposed at the top of the groove. The second elastic arm 114 and the groove enclose a receiving portion adapted to the outer wall of the rotating shaft 120. One end of the rotating shaft 120 passes through the lateral shaft hole and the through hole of the first elastic arm 113 in sequence, and the other end is disposed within the receiving portion.
[0030] Specifically, the reflector bracket includes a housing 110 and a rotating shaft 120 disposed within the housing 110. The housing 110 is a semi-enclosed structure, which provides a mounting carrier for the rotating shaft 120. The reflector 210 can be disposed within the housing 110 via the rotating shaft 120 and can be rotated axially via the rotating shaft 120, thereby adjusting the imaging angle.
[0031] like Figure 1 As shown, a first mounting member 111 and a second mounting member 112 are disposed opposite to each other within the housing 110, wherein the first mounting member 111 and the second mounting member 112 are respectively used to assemble the opposite ends of the rotating shaft 120. The first mounting member 111 has a lateral shaft hole, which facilitates the installation of the rotating shaft 120 by allowing it to be inserted at an angle.
[0032] like Figure 1 As shown, a first elastic arm 113 protrudes from the end of the lateral shaft hole opposite to the second mounting member 112. The first elastic arm 113 has elastic deformation capability, and a through hole is formed in its middle. The end of the rotating shaft 120 can be tilted into the lateral shaft hole and extend into the through hole, achieving an interference fit with the first elastic arm 113, such as... Figure 3 As shown. After the rotating shaft 120 is inserted, the elastic arm generates radial elastic force due to the interference fit, tightly adhering to the outer wall of the rotating shaft 120, thereby eliminating the fit clearance between the rotating shaft 120 and the first elastic arm 113. Optionally, the first mounting member 111 is a mounting plate 111a disposed perpendicular to the bottom surface of the housing 110, with a lateral shaft hole disposed on the mounting plate 111a. The mounting plate 111a provides reliable support for the rotating shaft 120.
[0033] The second mounting member 112 has a groove that matches the shape of the outer wall of the rotating shaft 120, forming an arc-shaped structure. An arc-shaped second elastic arm 114 extends from the top of the groove, and the two together form a receiving portion, ensuring that the end of the rotating shaft 120 can be stably embedded. When the second elastic arm 114 is in an interference fit with the outer wall of the rotating shaft 120, it can generate uniform pressure through elastic deformation, eliminating gaps while limiting the rotation of the rotating shaft 120 and preventing vibration. Optionally, the second mounting member 112 can be a support block 112a, with the groove located on the top surface of the support block 112a. The support block 112a can further improve the support stability of the rotating shaft 120.
[0034] It should be noted that, firstly, in one possible implementation of this application, such as Figure 2 As shown, in order to further improve the ease of assembly of the rotating shaft 120, an opening 1141 is provided in the middle of the second elastic arm 114. The opening 1141 is connected to the receiving part, and one end of the rotating shaft 120 corresponding to the second mounting member 112 is set in the receiving part through the opening 1141.
[0035] The opening 1141 allows the second elastic arm 114 to elastically open. When the rotating shaft 120 is inserted, the elastic arm can deform outward due to the presence of the opening 1141, expanding the entrance size of the receiving part. After the rotating shaft 120 is in place, the second elastic arm 114 returns to its original position due to its own elasticity, clamping the outer wall of the rotating shaft 120. This facilitates the assembly of the rotating shaft 120 while also ensuring the limiting and gap-eliminating effect of the second mounting part 112 on the rotating shaft 120.
[0036] Secondly, in one possible embodiment of this application, a receiving cavity is provided inside the housing 110, located between the first mounting member 111 and the second mounting member 112. The receiving cavity is used to accommodate the reflector 210 of the head-up display. The receiving cavity provides space for the reflector 210 to rotate, preventing the reflector 210 from colliding with the housing 110 when rotating. The through hole of the first mounting member 111 and the receiving portion of the second mounting member 112 are at the same horizontal height, that is, the axis of the through hole and the receiving portion are aligned horizontally. This arrangement ensures that both ends of the rotating shaft 120 can be coaxially mounted, avoiding assembly stress or eccentric wear caused by height deviation, reducing torque deviation when the rotating shaft 120 rotates, and improving the stability of the reflector 210's movement.
[0037] The reflector bracket includes a housing 110 and a rotating shaft 120 disposed within the housing 110. The rotating shaft 120 supports the reflector 210 of the head-up display. The housing 110 includes a first mounting member 111 and a second mounting member 112 disposed opposite to each other. The first mounting member 111 has a lateral shaft hole, and a first elastic arm 113 protrudes from the end of the lateral shaft hole away from the second mounting member 112. The middle part of the first elastic arm 113 has a through hole disposed along the extension direction of the rotating shaft 120, and the through hole communicates with the lateral shaft hole. The first elastic arm 113 provides an elastic compensation structure to eliminate assembly gaps, and provides a possibility to solve the problems of movement, vibration and abnormal noise caused by wear after the rigid structure in the traditional installation method. At the same time, the lateral shaft hole allows the rotating shaft 120 to be assembled at an inclined angle without the need for additional fasteners as in the traditional installation method. The fixed rotating shaft 120 reduces installation materials and processes, improving production efficiency. The second mounting component 112 has a groove, and an arc-shaped second elastic arm 114 is provided at the top of the groove. The second elastic arm 114 and the groove enclose a receiving portion that fits the outer wall of the rotating shaft 120. The arc-shaped second elastic arm 114 can use its own elasticity to make an interference fit with the outer wall of the rotating shaft 120, on the one hand limiting the rotating shaft 120 and eliminating the fit clearance in this direction; on the other hand, the arc design facilitates the installation of the rotating shaft 120 and plays a guiding role. At the same time, during the rotation movement of the rotating shaft 120, it can maintain a stable fit through elastic compensation, further avoiding vibration and abnormal noise caused by increased clearance due to wear of the shaft hole. One end of the rotating shaft 120 passes through the lateral shaft hole and the through hole of the first elastic arm 113 in sequence, and the other end is located in the receiving portion. The above-mentioned reflector bracket facilitates installation, improves the rotation accuracy and stability of the main reflector 210, and reduces the possibility of vibration or abnormal noise of the main reflector 210.
[0038] In one embodiment of this application, at least one first annular groove is provided on the inner wall of the lateral shaft hole. The first annular groove is used to store lubricating grease. When there are multiple first annular grooves, they are arranged at intervals along the extension direction of the rotating shaft 120. In one specific embodiment of this application, there are three first annular grooves. Of course, this application does not impose any limitation on the number of first annular grooves, and the number of first annular grooves can also be one, two, etc. The arrangement of multiple first annular grooves makes the lubrication of the inner wall of the lateral shaft hole more uniform. Even if the grease in one groove is exhausted, other first annular grooves can still replenish it, maintaining the stability of the lubrication effect and further delaying the wear of the rotating shaft 120.
[0039] The first annular groove is provided on the mating surface of the lateral shaft hole and the rotating shaft 120. When the rotating shaft 120 passes through the lateral shaft hole, the first annular groove can form a sealed oil storage space. After the lubricating grease is filled, it is not easy to overflow, ensuring continuous lubrication during the long-term rotation of the rotating shaft 120. The lubricating grease can reduce the coefficient of friction between the rotating shaft 120 and the shaft hole, avoid heat and metal debris generated by dry friction, thereby extending the service life of the rotating shaft 120 and the housing 110.
[0040] Optionally, at least one second annular groove is provided at intervals on the outer wall of one end of the rotating shaft 120 corresponding to the lateral shaft hole. The second annular groove is used to store lubricating grease. When there are multiple second annular grooves, the multiple second annular grooves are arranged at intervals along the extension direction of the rotating shaft 120.
[0041] Similarly, the second annular groove is provided on the assembly surface of the lateral shaft hole and the rotating shaft 120. When the rotating shaft 120 passes through the lateral shaft hole, the second annular groove can form a sealed oil storage space. After the lubricating grease is filled, it is not easy to overflow, ensuring continuous lubrication during the long-term rotation of the rotating shaft 120.
[0042] In one possible embodiment of this application, a first annular groove may be provided only on the inner wall of the lateral shaft hole; in another possible embodiment of this application, a second annular groove may be provided only on the outer wall of the rotating shaft 120; of course, in addition to the above two embodiments, a first annular groove may be provided on the inner wall of the lateral shaft hole, and a second annular groove may also be provided on the outer wall of the rotating shaft 120, thereby forming an inner and outer bidirectional oil storage structure, which can further enhance the lubrication effect and reduce the possibility of the rotating shaft 120 vibrating or making abnormal noise during rotation.
[0043] For example, such as Figure 5 As shown, a rib 121 is provided on the side of the rotating shaft 120 facing the groove corresponding to one end of the second mounting part 112. An annular limiting groove is provided in the groove corresponding to the rib 121. The width of the rib 121 is equal to the width of the annular limiting groove, and the length of the rib 121 is less than the length of the annular limiting groove, so that the rib 121 can be locked in the annular limiting groove. The width direction is the extension direction of the rotating shaft 120, and the length direction is perpendicular to the width direction.
[0044] Specifically, such as Figure 5As shown, the rib 121 is disposed on the outer wall of the rotating shaft 120 corresponding to one end of the second mounting member 112, and faces the groove side, and has a strip-shaped or rectangular structure; the inner wall of the groove of the second mounting member 112 has an annular limiting groove corresponding to the position of the rib 121, and its width is perfectly matched with the rib 121, so that the rib 121 can be locked in the annular limiting groove, which has the effect of limiting the extension direction of the rotating shaft 120. At the same time, the length of the rib 121 is less than the length of the annular limiting groove, so that when the rotating shaft 120 rotates, the rib 121 can move together in the annular limiting groove, so as not to affect the rotation of the rotating shaft 120.
[0045] By setting the rib 121 and the annular limiting groove, the rotating shaft 120 can be limited along its extension direction, thereby preventing the reflector 210 from shaking or moving in that direction, and further improving the stability and accuracy of the rotation of the reflector 210.
[0046] Optionally, such as Figure 4 As shown, the second elastic arm 114 includes a first sub-elastic arm 1142 and a second sub-elastic arm 1143 separated by an opening 1141. The first sub-elastic arm 1142 is attached to the outer wall of the rotating shaft 120. The second sub-elastic arm 1143 includes a body 1143a and an extension arm 1143b connected to each other. The body 1143a is attached to the outer arm of the rotating shaft 120, and the extension arm 1143b is located at the end of the body 1143a and extends toward the side opposite to the groove.
[0047] Specifically, such as Figure 4 As shown, the first sub-elastic arm 1142 is directly attached to the outer wall of the rotating shaft 120. Its surface shape is adapted to the contour of the outer wall of the rotating shaft 120 to ensure close contact with the rotating shaft 120. The first sub-elastic arm 1142 generates radial pressure through its own elastic deformation, which is close to the outer wall of the rotating shaft 120 to achieve vertical positioning and gap elimination. Its attachment structure makes the pressure evenly distributed and avoids wear caused by local stress concentration.
[0048] The body 1143a of the second elastic arm 1143 is also attached to the outer wall of the rotating shaft 120, forming a circumferential structure around the rotating shaft 120 together with the first elastic arm 1142, further enhancing the clamping force. The attachment surface of the body 1143a is interference-fitted with the outer wall of the rotating shaft 120 to ensure the effect of elastic compensation of gaps; the extension arm 1143b is located at the end of the body 1143a and extends towards the side away from the groove, so that the opening 1141 of the second elastic arm 114 is trumpet-shaped. This arrangement can guide the rotating shaft 120 when it is inserted into the receiving part, guiding the rotating shaft 120 smoothly into the opening 1141, thereby improving the assembly convenience of the rotating shaft 120.
[0049] In another aspect of this application, a head-up display is provided, including a reflector 210 and a reflector bracket; the reflector bracket includes a housing 110 and a rotating shaft 120 disposed within the housing 110, the reflector bracket is disposed on the rotating shaft 120, and the opposite ends of the rotating shaft 120 are respectively connected to a first mounting member 111 and a second mounting member 112 within the housing 110.
[0050] Specifically, the reflector 210 is a key component of the head-up display for image projection, used to reflect the image projected by the light source and present it in front of the driver's line of sight; the reflector bracket provides mounting support for the reflector 210 and ensures its stability; the reflector 210 is mounted on the pivot 120 and can rotate around the axis of the pivot 120, thereby adjusting the height of the projected image. The specific structure and beneficial effects of the reflector bracket have been described in detail above and will not be repeated here.
[0051] The head-up display improves installation efficiency and enhances the imaging accuracy and stability of the reflector 210 by using a reflector bracket, reducing the possibility of image jitter or abnormal noises from rotating components.
[0052] The above description is merely an optional embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
[0053] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.
