[0054] The limiting assembly 100 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0055] like Figures 1-6 As shown, according to the limit assembly 100 of an embodiment of the present invention, the limit assembly 100 is used for a head-up display device, the head-up display device includes a reflector 200, the limit assembly 100 includes a buckle 1 and a locking member 2, the buckle 1 and the locking member 2 are snap-connected and jointly define an axis hole 3, and the rotating shaft 300 of the reflector 200 is rotatably arranged in the axis hole 3.

[0056] Therefore, in the process of the driving mechanism driving the reflector 200 to rotate, the rotating shaft 300 is rotatably arranged in the shaft hole 3, so that the shaft hole 3 limits the movement of the rotating shaft 300 in multiple directions, so that the reflector 200 remains stable and precise during the rotation process, ensuring that the reflector 200 rotates around the axis of the rotating shaft 300 to avoid offset, thereby ensuring the effect of the reflector 200 reflecting the image on the front windshield, and improving the reliability of the reflector assembly 1000 using the limiting assembly 100.

[0057] At the same time, the buckle 1 and the locking member 2 are connected by snapping and jointly defining the shaft hole 3, so that the structure of the limit assembly 100 is simple, which facilitates the arrangement of the rotating shaft 300 of the reflector 200 in the shaft hole 3, thereby improving the assembly efficiency of the reflector assembly 1000 using the limit assembly 100, and eliminating the need for installation design and procedures of structures or components such as fasteners, thereby reducing costs and improving efficiency.

[0058] Furthermore, the rotating shaft 300 may be molded using a process that reduces surface roughness, including but not limited to surface finishing or high-gloss finishing, thereby reducing friction and noise between the rotating shaft 300 and the shaft hole 3 during rotation, thereby improving reliability. Alternatively, during assembly, a lubrication process may be used between the inner circumferential wall of the shaft hole 3 and the rotating shaft 300 to reduce friction and noise between the rotating shaft 300 and the shaft hole 3 during rotation, thereby improving reliability.

[0059] According to the embodiment of the present invention, the limit assembly 100 is used for a head-up display device, which includes a reflector 200. The limit assembly 100 includes a buckle 1 and a locking member 2. The buckle 1 and the locking member 2 are connected by a snap connection and together define an axial hole 3. The rotating shaft 300 of the reflector 200 is rotatably disposed in the axial hole 3, so that the axial hole 3 limits the movement of the rotating shaft 300 in multiple directions, so that the reflector 200 remains stable and accurate during rotation, avoids deviation, and improves the reliability of the reflector assembly 1000 using the limit assembly 100. At the same time, the limit assembly 100 has a simple structure and does not require the installation design and process of structures or components such as fasteners, thereby reducing costs and improving assembly efficiency.

[0060] In some embodiments of the present invention, Figure 3-Figure 6 As shown, the buckle 1 has a mounting groove 11, and at least a portion of the locking member 2 is located in the mounting groove 11 and defines an axial hole 3 between the locking member 2 and the bottom wall of the mounting groove 11. It is understood that during the assembly of the reflector assembly 1000 using the limit assembly 100, the rotating shaft 300 of the reflector 200 is first extended into the mounting groove 11, and then the buckle 1 and the locking member 2 are engaged and connected, so that the rotating shaft 300 of the reflector 200 is rotatably disposed in the axial hole 3.

[0061] In some embodiments of the present invention, Figure 3 and Figure 6 As shown, the bottom wall of the mounting groove 11 is an arc-shaped surface that convexly faces away from the mounting groove 11. Therefore, during the rotation of the rotating shaft 300, this configuration can reduce frictional resistance and noise between the bottom wall of the mounting groove 11 and the rotating shaft 300, ensuring that the rotating shaft 300 rotates smoothly in the shaft hole 3 without excessive friction or looseness, further improving reliability.

[0062] In some embodiments of the present invention, Figure 3 and Figure 6 As shown, the buckle 1 includes a first main body portion 12, a first clamping portion 13 and a second clamping portion 14. The first clamping portion 13 and the second clamping portion 14 are spaced apart on the first main body portion 12, and the mounting groove 11 is located between the first clamping portion 13 and the second clamping portion 14. The first clamping portion 13 and the second clamping portion 14 are clamped and connected to the locking member 2.

[0063] Thus, through such an arrangement, the first clamping portion 13 and the second clamping portion 14 limit the rotation shaft 300 located in the shaft hole 3, and the first clamping portion 13 and the second clamping portion 14 are clamped and connected with the locking member 2, further ensuring the limit of the rotation shaft 300, ensuring the stability and accuracy of the reflector 200 during the rotation process. At the same time, the first clamping portion 13 and the second clamping portion 14 are clamped and connected with the locking member 2, realizing the clamping connection between the buckle 1 and the locking member 2, ensuring that the locking member 2 located in the installation groove 11 and the bottom wall of the installation groove 11 limit the rotation shaft 300, further ensuring the stability and accuracy of the reflector 200 during the rotation process.

[0064] In some embodiments of the present invention, Figure 2 、 Figure 3 、 Figure 6 and Figure 9 As shown, the locking member 2 includes a second main body portion 22 and a cross beam 21. The cross beam 21 is connected to the second main body portion 22 and at least partially extends into the mounting groove 11 and defines an axial hole 3 between the second main body portion 22 and the bottom wall of the mounting groove 11. The second main body portion 22 has a first clamping protrusion 2211 clamped to the first clamping portion 13 and a second clamping protrusion 2221 clamped to the second clamping portion 14.

[0065] Thus, the shaft hole 3 is defined between the crossbeam 21 and the bottom wall of the mounting groove 11, so that the crossbeam 21 and the bottom wall of the mounting groove 11 limit the rotation axis 300, ensuring the stability and accuracy of the reflector 200 during the rotation process. At the same time, the first clamping portion 13 is clamped to the first clamping protrusion 2211, and the second clamping portion 14 is clamped to the second clamping protrusion 2221, so that the first clamping portion 13 and the second clamping portion 14 are clamped to the locking member 2, thereby achieving the clamping connection between the buckle 1 and the locking member 2.

[0066] In some embodiments of the present invention, Figure 3 、 Figure 6 and Figure 9 As shown, the second main body 22 has a first cantilever spring buckle 221 and a second cantilever spring buckle 222, which are respectively located on both sides of the beam 21, and a first latching protrusion 2211 and a second latching protrusion 2221 are respectively provided on the first cantilever spring buckle 221 and the second cantilever spring buckle 222.

[0067] It can be understood that in the process of the first clamping portion 13 and the first clamping protrusion 2211 and the second clamping portion 14 and the second clamping protrusion 2221, the first cantilever spring buckle 221 and the second cantilever spring buckle 222 have a certain elastic deformation ability, which reduces the difficulty of clamping, improves the assembly efficiency, ensures the strength of the clamping connection, and improves the reliability of the limit assembly 100.

[0068] Specifically, the second main body portion 22 includes a main body portion, a first cantilever spring buckle 221 and a second cantilever spring buckle 222. A first deformation groove is provided between the first cantilever spring buckle 221 and the main body portion, and a second deformation groove is provided between the second cantilever spring buckle 222 and the main body portion. In the process of clamping the first clamping portion 13 and the first clamping protrusion 2211 and clamping the second clamping portion 14 and the second clamping protrusion 2221, the deformation effect of the first deformation groove and the second deformation groove reduces the difficulty of clamping and improves the assembly efficiency.

[0069] In some embodiments of the present invention, Figure 3 、 Figure 6 and Figure 9 As shown, the second main body portion 22 is annular and forms a cavity 223, the crossbeam 21 is located in the cavity 223 and divides the cavity 223 into a first sub-cavity 2231 and a second sub-cavity 2232, the first clamping portion 13 extends into the first sub-cavity 2231, and the second clamping portion 14 extends into the second sub-cavity 2232, the first cantilever spring buckle 221 is located on the inner side wall of the first sub-cavity 2231 away from the second sub-cavity 2232, and the second cantilever spring is located on the inner side wall of the second sub-cavity 2232 away from the first sub-cavity 2231.

[0070] Thus, through this arrangement, the first clamping protrusion 2211 and the second clamping protrusion 2221 are respectively clamped to the first clamping portion 13 and the second clamping portion 14 in directions away from each other, further ensuring the clamping strength of the locking member 2 and the buckle 1 and limiting the rotation shaft 300 located in the shaft hole 3, ensuring the stability and accuracy of the reflector 200 during the rotation process. At the same time, the first clamping portion 13 and the second clamping portion 14 are located in the cavity 223, so that the second body portion 22 protects the mating portion between the first clamping portion 13 and the first clamping protrusion 2211 and the mating portion between the second clamping portion 14 and the second clamping protrusion 2221, further ensuring a reliable connection between the two.

[0071] In some embodiments of the present invention, Figure 3 、 Figure 6 and Figure 9 As shown, the first clamping portion 13 and the second clamping portion 14 include a connecting portion 131 and a clamping protrusion 132, the connecting portion 131 is connected to the first main body portion 12, the clamping protrusion 132 is located on the side of the connecting portion 131 away from the mounting groove 11, the clamping protrusion 132 of the first clamping portion 13 is located on the side of the first clamping protrusion 2211 away from the bottom wall of the mounting groove 11 and abuts against the first clamping protrusion 2211, the clamping protrusion 132 of the second clamping portion 14 is located on the side of the second clamping protrusion 2221 away from the bottom wall of the mounting groove 11 and abuts against the second clamping protrusion 2221, and in the direction from the opening to the bottom wall of the mounting groove 11, the clamping protrusions 132 of the first clamping portion 13 and the second clamping portion 14 are inclined away from the side wall surfaces of the mounting groove 11 toward the direction away from each other.

[0072] Thus, the first clamping portion 13 and the first clamping protrusion 2211 are clamped together by the clamping protrusion 132 of the first clamping portion 13 being located on the side of the bottom wall of the first clamping protrusion 2211 away from the installation groove 11 and abutting against the first clamping protrusion 2211. The second clamping portion 14 and the second clamping protrusion 2221 are clamped together by the clamping protrusion 132 of the second clamping portion 14 being located on the side of the bottom wall of the second clamping protrusion 2221 away from the installation groove 11 and abutting against the second clamping protrusion 2221, thereby realizing the clamping of the buckle 1 and the locking member 2. At the same time, since the locking member 2 is engaged with the buckle 1 in the direction from the opening of the mounting groove 11 to the bottom wall, in the direction from the opening of the mounting groove 11 to the bottom wall, the protrusions 132 of the first clamping portion 13 and the second clamping portion 14 are inclined away from the side wall surfaces of the mounting groove 11 toward directions away from each other, which plays a certain guiding role in the assembly process and reduces the difficulty of engaging the first clamping portion 13 and the first clamping protrusion 2211 and the second clamping portion 14 and the second clamping protrusion 2221, thereby improving the assembly efficiency.

[0073] In some embodiments of the present invention, Figure 3 、 Figure 6 and Figure 9 As shown, the first clamping portion 13 and the second clamping portion 14 include a connecting portion 131 and a clamping protrusion 132, the connecting portion 131 is connected to the first main body portion 12, the clamping protrusion 132 is located on the side of the connecting portion 131 away from the mounting groove 11, the clamping protrusion 132 of the first clamping portion 13 is located on the side of the first clamping protrusion 2211 away from the bottom wall of the mounting groove 11 and abuts against the first clamping protrusion 2211, the clamping protrusion 132 of the second clamping portion 14 is located on the side of the second clamping protrusion 2221 away from the bottom wall of the mounting groove 11 and abuts against the second clamping protrusion 2221, and in the direction from the opening of the mounting groove 11 to the bottom wall, the side walls of the first clamping protrusion 2211 and the second clamping protrusion 2221 are inclined toward each other.

[0074] Thus, the first clamping portion 13 and the first clamping protrusion 2211 are clamped together by the clamping protrusion 132 of the first clamping portion 13 being located on the side of the bottom wall of the first clamping protrusion 2211 away from the installation groove 11 and abutting against the first clamping protrusion 2211. The second clamping portion 14 and the second clamping protrusion 2221 are clamped together by the clamping protrusion 132 of the second clamping portion 14 being located on the side of the bottom wall of the second clamping protrusion 2221 away from the installation groove 11 and abutting against the second clamping protrusion 2221, thereby realizing the clamping of the buckle 1 and the locking member 2. At the same time, since the locking member 2 is engaged with the buckle 1 in the direction from the opening of the mounting groove 11 to the bottom wall, the first clamping protrusion 2211 and the second clamping protrusion 2221 are inclined toward each other's side wall surfaces in the direction from the opening of the mounting groove 11 to the bottom wall, which plays a certain guiding role in the assembly process and reduces the difficulty of engaging the first clamping portion 13 and the first clamping protrusion 2211 and the second clamping portion 14 and the second clamping protrusion 2221, thereby improving the assembly efficiency.

[0075] In some embodiments of the present invention, Figure 3 、 Figure 6 and Figure 9 As shown, the first clamping portion 13 and the second clamping portion 14 include a connecting portion 131 and a clamping protrusion 132, the connecting portion 131 is connected to the first main body portion 12, the clamping protrusion 132 is located on the side of the connecting portion 131 away from the mounting groove 11, the clamping protrusion 132 of the first clamping portion 13 is located on the side of the first clamping protrusion 2211 away from the bottom wall of the mounting groove 11 and abuts against the first clamping protrusion 2211, the clamping protrusion 132 of the second clamping portion 14 is located on the side of the second clamping protrusion 2221 away from the bottom wall of the mounting groove 11 and abuts against the second clamping protrusion 2221, in the direction from the opening to the bottom wall of the mounting groove 11, the clamping protrusions 132 of the first clamping portion 13 and the second clamping portion 14 are inclined away from the side wall surface of the mounting groove 11 toward the direction away from each other, and the side wall surfaces of the first clamping protrusion 2211 and the second clamping protrusion 2221 are inclined away from each other.

[0076] Thus, the first clamping portion 13 and the first clamping protrusion 2211 are clamped together by the clamping protrusion 132 of the first clamping portion 13 being located on the side of the bottom wall of the first clamping protrusion 2211 away from the installation groove 11 and abutting against the first clamping protrusion 2211. The second clamping portion 14 and the second clamping protrusion 2221 are clamped together by the clamping protrusion 132 of the second clamping portion 14 being located on the side of the bottom wall of the second clamping protrusion 2221 away from the installation groove 11 and abutting against the second clamping protrusion 2221, thereby realizing the clamping of the buckle 1 and the locking member 2.

[0077] At the same time, since the locking member 2 is engaged with the buckle 1 in the direction from the opening of the mounting groove 11 to the bottom wall, in the direction from the opening of the mounting groove 11 to the bottom wall, the clamping protrusions 132 of the first clamping portion 13 and the second clamping portion 14 are inclined away from the side wall surfaces of the mounting groove 11 toward the direction away from each other, and the side wall surfaces of the first clamping protrusion 2211 and the second clamping protrusion 2221 are inclined toward the direction away from each other, which further plays a certain guiding role in the assembly process and reduces the difficulty of clamping the first clamping portion 13 and the first clamping protrusion 2211 and the second clamping portion 14 and the second clamping protrusion 2221, thereby further improving the assembly efficiency.

[0078] In some embodiments of the present invention, Figure 9 As shown, a stopper 224 is provided on at least one of the two opposing inner walls of the first subcavity 2231, in a direction perpendicular to the arrangement of the first subcavity 2231 and the second subcavity 2232. Thus, the provision of the stopper 224 further limits the position of the first engaging portion 13, enhancing the engagement strength between the first engaging portion 13 and the locking member 2, thereby effectively ensuring that the shaft hole 3 limits the position of the rotating shaft 300.

[0079] In some embodiments of the present invention, Figure 9 As shown, a stopper 224 is provided on at least one of the two opposing inner walls of the second subcavity 2232, in a direction perpendicular to the arrangement of the first subcavity 2231 and the second subcavity 2232. Thus, the stopper 224 further limits the position of the second engaging portion 14, enhancing the engagement strength between the second engaging portion 14 and the locking member 2, thereby effectively ensuring that the shaft hole 3 limits the position of the rotating shaft 300.

[0080] In some embodiments of the present invention, Figure 9 As shown, in a direction perpendicular to the arrangement direction of the first sub-cavity 2231 and the second sub-cavity 2232, a limiting block 224 is provided on at least one of the two opposing inner walls of the first sub-cavity 2231, and a limiting block 224 is provided on at least one of the two opposing inner walls of the second sub-cavity 2232. Thus, the limiting block 224 located in the first sub-cavity 2231 can further limit the first clamping portion 13, thereby improving the clamping strength between the first clamping portion 13 and the locking member 2. Furthermore, the limiting block 224 located in the second sub-cavity 2232 can further limit the second clamping portion 14, thereby improving the clamping strength between the second clamping portion 14 and the locking member 2, thereby effectively ensuring that the shaft hole 3 limits the position of the rotating shaft 300.

[0081] In some embodiments of the present invention, Figure 3 、 Figure 6 and Figure 9As shown, in the direction from the opening of the mounting groove 11 to the bottom wall, the locking member 2 protrudes beyond the bottom wall of the mounting groove 11. The locking member 2 has notches 225 on two opposing walls that mate with the shaft hole 3. Thus, the notches 225 allow the rotating shaft 300 to pass through, preventing motion interference between the rotating shaft 300 and the locking member 2, thereby improving the reliability of the position limiting assembly 100.

[0082] In some embodiments, the locking member 2 is a single piece. This arrangement improves the overall strength of the locking member 2, ensuring the strength of the connection between the locking member 2 and the buckle 1. It also reduces assembly steps and improves assembly efficiency. Alternatively, the locking member 2 can be manufactured using a molding process such as injection molding, CNC (Computer Numerical Control), or powder metallurgy.

[0083] In some embodiments, the buckle 1 is an integral part. Thus, such a configuration improves the overall strength of the buckle 1 and ensures the connection strength between the locking member 2 and the buckle 1. At the same time, it reduces the assembly process and improves the assembly efficiency.

[0084] The following describes the reflector assembly 1000 according to an embodiment of the present invention.

[0085] According to the reflector assembly 1000 of the embodiment of the present invention, Figures 1-9 As shown, the head-up display device includes a limit assembly 100, a reflector 200 and a rotating shaft 300. The rotating shaft 300 is connected to the reflector 200 and is rotatably disposed in the shaft hole 3.

[0086] Therefore, in the process of the driving mechanism driving the reflector 200 to rotate, the rotating shaft 300 is rotatably arranged in the shaft hole 3, so that the shaft hole 3 limits the movement of the rotating shaft 300 in multiple directions, so that the reflector 200 remains stable and precise during the rotation process, ensuring that the reflector 200 rotates around the axis of the rotating shaft 300 to avoid offset, thereby ensuring the effect of the reflector 200 reflecting the image on the front windshield, and improving the reliability of the reflector assembly 1000 using the limiting assembly 100.

[0087] At the same time, the buckle 1 and the locking member 2 are connected by snapping and jointly defining the shaft hole 3, so that the structure of the limit assembly 100 is simple, which facilitates the arrangement of the rotating shaft 300 of the reflector 200 in the shaft hole 3, thereby improving the assembly efficiency of the reflector assembly 1000 using the limit assembly 100, and eliminating the need for installation design and procedures of structures or components such as fasteners, thereby reducing costs and improving efficiency.

[0088] According to the reflector assembly 1000 of the embodiment of the present invention, a limit assembly 100 is provided. The limit assembly 100 includes a buckle 1 and a locking member 2. The buckle 1 and the locking member 2 are snap-connected and together define an axial hole 3. The rotating shaft 300 of the reflector 200 is rotatably disposed in the axial hole 3, so that the axial hole 3 limits the movement of the rotating shaft 300 in multiple directions, so that the reflector 200 remains stable and accurate during rotation, avoids deviation, and improves the reliability of the reflector assembly 1000. At the same time, the limit assembly 100 has a simple structure and does not require the installation design and process of structures or components such as fasteners, thereby reducing costs and improving assembly efficiency.

[0089] In some embodiments of the present invention, Figure 4 and Figure 8 As shown, there are two rotating shafts 300, which are respectively provided at opposite ends of the reflector 200, and two limiting assemblies 100 are provided, one for each rotating shaft 300. It can be understood that the two rotating shafts 300 are coaxial. Therefore, during the rotation of the reflector 200, by providing the rotating shafts 300 at opposite ends of the reflector 200, it is possible to better resist vibration and deviation caused by imbalance or external torque, ensure that the reflector 200 rotates around the axis of the rotating shafts 300, and improve the reliability of the reflector assembly 1000. At the same time, the two rotating shafts 300 are respectively limited by the shaft holes 3 of the two limiting assemblies 100, further ensuring the stability and precision of the reflector 200 during the rotation process.

[0090] In some embodiments of the present invention, Figure 2 and Figure 8 As shown, the reflector assembly 1000 further includes a stopper protrusion 400. The stopper protrusion 400 is disposed around the outer circumferential wall of the rotating shaft 300 and is located at the end of the rotating shaft 300 proximal to the reflector 200. The stopper protrusion 400 is located outside the shaft hole 3 and is configured to abut against the stopper assembly 100. Thus, by having the stopper protrusion 400 located outside the shaft hole 3 and abutting against the stopper assembly 100, the rotating shaft 300 is further limited in position, ensuring that the rotating shaft 300 is rotatably disposed within the shaft hole 3. Furthermore, the stopper protrusion 400 serves as a foolproofing mechanism during assembly, reducing assembly difficulty and improving efficiency.

[0091] Furthermore, the outer wall of the notch 225 of the locking member 2, which mates with the shaft hole 3, abuts against the limiting protrusion 400, thereby achieving the limiting function of the limiting protrusion 400. Furthermore, the locking member 2 and the limiting protrusion 400 are formed using a molding process that reduces surface roughness, including but not limited to surface gloss or high-gloss treatments, thereby reducing friction and noise during the rotation of the rotating shaft 300 and improving reliability.

[0092] In some embodiments of the present invention, Figure 8As shown, the reflector assembly 1000 further includes a reinforcing rib 500. The reinforcing rib 500 is provided on the outer surface of the reflector 200 and is connected to the reflector 200. The rotating shaft 300 is also connected to the reinforcing rib 500. Thus, the reinforcing rib 500 effectively improves the structural strength of the reflector 200 and the rotating shaft 300, ensuring reliable and stable rotation of the reflector 200, and effectively improving the reliability of the reflector assembly 1000.

[0093] In some embodiments of the present invention, Figure 1 、 Figure 4 and Figure 7 As shown, the reflector assembly 1000 further includes a housing 600. The housing 600 has a receiving space 601, in which the reflector 200 is rotatably disposed. The buckle 1 is located within the receiving space 601 and connected to the housing 600. Thus, the housing 600 effectively protects the reflector 200 and the buckle 1 within the receiving space 601, thereby improving overall reliability.

[0094] In some embodiments, the reflector assembly 1000 is a one-piece component. Thus, such a configuration improves the overall strength of the reflector assembly 1000 , reduces assembly steps, and improves assembly efficiency.

[0096] The head-up display device according to an embodiment of the present invention includes a reflector assembly 1000 .

[0097] According to an embodiment of the present invention, a head-up display device is provided with a reflector assembly 1000. The limit assembly 100 includes a buckle 1 and a locking member 2. The buckle 1 and the locking member 2 are connected by a snap connection and together define an axis hole 3. The rotating shaft 300 of the reflector 200 is rotatably disposed in the axis hole 3, so that the axis hole 3 limits the movement of the rotating shaft 300 in multiple directions, thereby maintaining the stability and precision of the reflector 200 during rotation, preventing deviation and improving the reliability of the head-up display device. Furthermore, the limit assembly 100 has a simple structure and does not require the installation design and process of structures or components such as fasteners, thereby reducing costs and improving assembly efficiency.

Furthermore, the limit assembly 100 has a simple structure and does not require the installation design and process of structures or components such as fasteners, thereby reducing costs and improving assembly efficiency.
