Description

Technical Field

[0001] The present invention relates to the technical field of head-up display, and in particular to a reflector fixing bracket and a head-up display device. Background Art

[0002] With the development of new energy vehicles, in-vehicle HUDs (Head Up Displays) have evolved from C-HUD to W-HUD and then to AR-HUD. New energy vehicles offer more space for larger AR-HUDs, which display more content, integrating virtual information with the actual road, providing users with a human-machine interaction method that improves driving safety and enhances driving pleasure. To capture more display content, a larger, flip-up mirror is required. Larger mirrors place greater demands on vibration resistance, and longer virtual image distances require higher mirror flipping precision to avoid unsatisfactory image position accuracy.

[0003] Due to the vertical clearance between the reflector's rotation axis and the reflector's mounting bracket, the reflector can vibrate during rotation. To prevent this, existing mounting brackets often use a non-elastic, tight-fitting structure or tighten the reflector's edges to eliminate the clearance. The former results in jerky mirror rotation, affecting image position accuracy, while the latter can cause the mirror to deform and reduce image quality. Summary of the Invention

[0030] This embodiment provides a reflector fixing bracket 100 for fixing a reflector 200 in a head-up display device. The reflector 200 includes a mirror surface 210 and a rotation axis 220 arranged at the edge of the mirror surface 210. The reflector 200 is rotatably set on the reflector fixing bracket 100 via the rotation axis 220 thereon.

[0031] For details, please refer to Figure 1 and Figure 2 The reflector fixing bracket 100 includes a bracket body 110 and a spring-pressing assembly 120. The bracket body 110 is provided with a support groove 111, which is used to accommodate the rotation axis 220 of the reflector 200. It can be understood that the number of support grooves 111 is equal to the number of rotation axis 220 and is arranged in a one-to-one correspondence. The support groove 111 has at least a first opening and a second opening connected to each other, wherein the rotation axis 220 is placed in the support groove 111 through the first opening, and the second opening is used to allow the end of the rotation axis 220 to extend out of the support groove 111; preferably, the plane where the first opening is located is perpendicular to the plane where the second opening is located, and the plane where the first opening is located is also parallel to the axis of the rotation axis 220.

[0032] After the rotating shaft 220 is placed in the support groove 111, the rotating shaft 220 may vibrate in a direction perpendicular to the bottom surface of the support groove 111. Therefore, a spring-pressing assembly 120 is provided at the first opening to press the rotating shaft 220 tightly into the support groove 111. The spring-pressing assembly 120 includes a sliding bracket 121, a sliding spring block 122 and an elastic member 123. The sliding bracket 121 is fixed to the bracket body 110. The sliding spring block 122 is slidably provided in the sliding bracket 121. One end of the elastic member 123 abuts against the sliding bracket 121 and the other end abuts against the sliding spring block 122. The elastic deformation direction of the elastic member 123 is parallel to the sliding direction of the sliding spring block 122. The sliding spring block 122 is provided corresponding to the first opening of the support groove 111 to press the rotating shaft 220 tightly into the support groove 111. After the reflector 200 and the spring-pressing assembly 120 are installed, the sliding spring block 122 of the spring-pressing assembly 120 abuts against the rotating shaft 220 of the reflector 200. At the same time, the elastic member 123 is in a deformed energy storage state, which applies a pressure perpendicular to the bottom surface of the support groove 111 to the rotating shaft 220 to limit the shaking of the rotating shaft 220 in this direction. Preferably, the bottom surface of the support groove 111 is horizontal, and the sliding direction of the sliding spring block 122 and the elastic deformation direction of the elastic member 123 are both parallel to the vertical direction. For example, the sliding bracket 121 is fixed to the bracket body 110 by screws 130.

[0033] The reflector fixing bracket 100 employs an elastic member 123 to compress the rotating shaft 220 of the reflector 200 in a direction perpendicular to the bottom surface of the support groove 111. This not only eliminates assembly play, preventing vibration, noise, and image jitter, but also ensures smooth rotation of the reflector 200, prevents locking of the rotating structure, and ensures accurate image position adjustment. Furthermore, this reduces the precision requirements for the bracket body 110, allowing for greater tolerances and effectively reducing costs.

[0034] Optionally, in one possible implementation of the embodiment of the present invention, the sliding spring block 122 includes a sliding rod 1221 and a spring block 1222. The sliding rod 1221 slides back and forth within the sliding bracket 121, and the spring block 1222 is used to abut against the rotating shaft 220 of the reflector 200. The spring block 1222 includes a first limiting portion 1223, a connecting portion 1224, and a second limiting portion 1225 connected in sequence. The connecting portion 1224 is fixedly connected to the sliding rod 1221, and the first limiting portion 1223 and the second limiting portion 1225 are arranged in an "eight" shape. When the spring block 1222 abuts against the rotating shaft 220, the first limiting portion 1223 and the second limiting portion 1225 drive the rotating shaft 220 to hold it tightly, thereby eliminating assembly gaps in two opposite directions parallel to the bottom surface of the support groove 111. Elastic member 123 is mounted on slide bar 1221, which limits the position of elastic member 123 to prevent it from deforming in a non-elastic direction when subjected to force. Elastic member 123 has two opposing ends along the elastic deformation direction: one end abuts against connection portion 1224 of spring block 1222, and the other end abuts against sliding bracket 121. Thus, as spring block 1222 slides back and forth, elastic member 123 can store and release energy.

[0035] Optionally, in one implementation of the present invention, the elastic member 123 is a compression spring. Using the compression spring to compress the rotating shaft 220 of the reflector 200 can accurately control the force acting on the reflector 200, avoid interference or looseness, and ensure that the rotating shaft 220 is smoothly loaded along the direction of elastic deformation of the compression spring, thereby ensuring smooth rotation of the reflector 200.

[0036] Optionally, in one achievable method of an embodiment of the present invention, each of the support grooves 111 and the spring-pressing assembly 120 includes two, the two support grooves 111 being used to respectively accommodate the first rotation axis and the second rotation axis relatively arranged on the reflector 200, and the two spring-pressing assemblies 120 being used to respectively press the first rotation axis and the second rotation axis into the support grooves 111.

[0037] The reflector 200 includes two rotation axes 220: a first rotation axis and a second rotation axis. The first rotation axis and the second rotation axis are respectively arranged at two opposite edges of the mirror surface 210. The axis of the first rotation axis is parallel to the axis of the second rotation axis. Preferably, the first rotation axis and the second rotation axis are arranged coaxially. Accordingly, the bracket body 110 is provided with two support grooves 111, respectively for accommodating the first rotation axis and the second rotation axis. The spring-pressing assemblies 120 include two, one for pressing the first rotation axis and the other for pressing the second rotation axis.

[0038] Please refer to Figure 3 and Figure 4Optionally, in one possible implementation of the embodiment of the present invention, the bracket body 110 has a supporting surface, which is used to abut against the end surface of the first rotation shaft to limit the reflector 200 in the axial direction of the first rotation shaft. The reflector fixing bracket 100 also includes a first torsion spring 140, wherein the first torsion arm 141 of the first torsion spring 140 abuts against the bracket body 110, and the second torsion arm 142 abuts against the end surface of the second rotation shaft to press the reflector 200 along the axial direction of the second rotation shaft.

[0039] The first torsion spring 140 cooperates with the abutting surface on the bracket body 110 to eliminate the axial fit clearance of the reflector 200, thereby preventing the reflector 200 from axially moving and avoiding vibration and abnormal noise. The first torsion spring 140 applies force to the end face of the second rotation axis of the reflector 200. The magnitude of the force is easy to design and test, and can ensure that the force on the end face is uniform and does not change with the rotation of the reflector 200, allowing the reflector 200 to rotate smoothly. In addition, the first torsion spring 140 applies force to the end face of the second rotation axis of the reflector 200, and does not need to act directly on the imaging edge of the reflector 200 to eliminate the fit clearance, thereby avoiding distortion of the imaging image due to deformation of the reflector 200.

[0040] It should be noted that the first torsion arm 141 of the first torsion spring 140 and the bracket body 110 can achieve abutment by pressing the first torsion arm 141 against the bracket body 110, or by a fixed connection between the two. In addition, the first torsion arm 141 of the first torsion spring 140 can directly abut the bracket body 110, or can abut against the bracket body 110 indirectly through another structure fixedly connected to the bracket body 110.

[0041] Optionally, in one achievable method of an embodiment of the present invention, the first torsion spring 140 is arranged on a sliding bracket 121 arranged corresponding to the second rotation axis, and the reflector fixing bracket 100 also includes a torsion spring pressure block 150, which is fixedly connected to the sliding bracket 121 to press the first torsion spring 140 onto the sliding bracket 121 to prevent the spiral part of the first torsion spring 140 from moving; the first torsion arm 141 of the first torsion spring 140 is abutted against the sliding bracket 121, and because the sliding bracket 121 is fixedly connected to the bracket body 110, the first torsion arm 141 indirectly achieves abutment with the bracket body 110 through the sliding bracket 121.

[0042] Optionally, in one achievable method of an embodiment of the present invention, the second torsion arm 142 of the first torsion spring 140 is inserted into the limiting groove 221 on the end face of the second rotating shaft, and the diameter of the end of the second torsion arm 142 is smaller than the width of the limiting groove 221. With such an arrangement, when the reflector 200 rotates, the bottom of the limiting groove 221 can rotate relative to the second torsion arm 142, which can ensure that the first torsion spring 140 presses the reflector 200 axially, and can also avoid the first torsion spring 140 interfering with the rotation of the reflector 200.

[0043] Please refer to Figure 1 and Figure 3 Optionally, one possible implementation of the embodiment of the present invention further includes a motor 161, a gear 163, and a sector rack 164. The output shaft of the motor 161 is fixedly connected to the gear 163, which meshes with the sector rack 164. The sector rack 164 is fixedly connected to the rotation shaft 220, and the rotation axis of the sector rack 164 coincides with the axis of the rotation shaft 220. The motor 161 drives the gear 163 to rotate, and the sector rack 164 rotates about its rotation axis under the drive of the gear 163. In this way, the tilt angle of the reflector 200 can be adjusted.

[0044] Optionally, an achievable embodiment of the present invention further includes a second torsion spring 170, wherein the third torsion arm of the second torsion spring 170 abuts against the bracket body 110, and the fourth torsion arm 171 abuts against the sector rack 164, and the fourth torsion arm 171 provides pressure on the sector rack 164 toward the gear 163 to eliminate the side clearance between the sector rack 164 and the gear 163.

[0045] It should be noted that the abutment between the third torsion arm of the second torsion spring 170 and the bracket body 110 can be achieved by pressing the third torsion arm against the bracket body 110, or by a fixed connection between the two. Furthermore, the third torsion arm of the second torsion spring 170 can abut the bracket body 110 directly, or indirectly, through another structure fixedly connected to the bracket body 110. The abutment relationship between the fourth torsion arm 171 and the sector rack 164 is similar and will not be further described here.

[0046] For example, a hook 1641 is provided on the side wall of the sector rack 164, and the fourth torsion arm 171 of the second torsion spring 170 is pressed against the inner wall of the hook 1641; a motor mounting seat 162 is also provided on the bracket body 110, and the motor mounting seat 162 is used to fix the motor 161, and the third torsion arm of the second torsion spring 170 is fixed on the motor mounting seat 162.

[0047] Optionally, in one possible implementation of the embodiment of the present invention, the bracket body 110 is further provided with an in-position switch plate 180. The in-position switch plate 180 can be closed under the drive of the mirror surface 210 of the reflector 200 and automatically opened when separated from the reflector 200. The in-position switch plate 180 is used to determine whether the reflector 200 has rotated to the in-position position, or can serve as a zero point reference for the rotation of the reflector 200.

[0048] This embodiment also provides a head-up display device, including a reflector 200 and a reflector fixing bracket 100 as described above. The reflector 200 includes a mirror surface 210 and a rotating shaft 220 arranged at the edge of the mirror surface 210. The rotating shaft 220 is placed in the support groove 111 of the reflector fixing bracket 100. The sliding spring block 122 of the reflector fixing bracket 100 presses the rotating shaft 220 against the bracket body 110.

[0049] The head-up display device includes the same structure and benefits as the reflector fixing bracket 100 in the aforementioned embodiment. The structure and benefits of the reflector fixing bracket 100 have been described in detail in the aforementioned embodiment and will not be repeated here.

[0050] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
