[0047] See also Figures 1 to 10 As shown, the present application provides a reflective assembly bracket for a head-up display system, and the reflective assembly bracket includes a first bracket unit 1000 and a second bracket unit 2000. The first bracket unit 1000 includes a first support body 1100 and a second support body 1200, and the second bracket unit 2000 is arranged between the first support body 1100 and the second support body 1200 of the first bracket unit 1000. Among them, the second bracket unit 2000 includes at least two fixed body members 2100, each of which has a first connecting portion 2110 and a second connecting portion 2120, and the first connecting portions 2110 of several fixed body members 2100 are connected to the first support body member 1100, and the second connecting portions 2120 of several fixed body members 2100 are connected to the second support body member 1200, and each fixed body member 2100 is provided with a fixed assembly portion 2130, and several fixed body members 2100 are used to assemble the reflective lens together through the several fixed assembly portions 2130.

[0048] The first supporting body 1100 and the second supporting body 1200 in the first bracket unit 1000 and the fixed body 2100 in the second bracket unit 2000 can be constructed using a variety of structures. For example, the first supporting body 1100, the second supporting body 1200 and the fixed body 2100 are configured as rod-shaped structures, plate-shaped structures, and other regular structures or irregular structures. Those skilled in the art can select a suitable structure to construct the first supporting body 1100, the second supporting body 1200 and the fixed body 2100 according to actual needs, and no limitation is made herein.

[0049] For example, in one embodiment, the fixed body 2100 may be configured as a linear rod-shaped member, and the first connection portion 2110 and the second connection portion 2120 of the fixed body 2100 are located at both ends of the fixed body 2100. In this case, the fixed body 2100 has a curvature along the direction from the first connection portion 2110 to the second connection portion 2120, and the curvature from the first connection portion 2110 to the second connection portion 2120 can be set to a suitable curvature radius according to requirements, so that the curvature radius is consistent with the curvature of the reflective lens.

[0050] The fixed assembly part 2130 is located on a side surface of the fixed main body 2100 that is in a concave state, so that the reflective lens can be assembled on several fixed assembly parts 2130 of several fixed main bodies 2100 through various feasible methods such as bonding, clamping, and threaded connection, so that the reflective lens can be assembled together through several fixed main bodies 2100, thereby improving the assembly stability of the reflective lens.

[0051] Based on the linear rod structure of the fixed main body 2100, such as Figure 1 As shown, each fixed body 2100 may be provided with a plurality of fixed assembly parts 2130, and the plurality of fixed assembly parts 2130 may be linearly distributed on the surface of the fixed body 2100 along the direction from the first connection part 2110 to the second connection part 2120. Therefore, each fixed body 2100 may have a plurality of fixed assembly parts 2130, which can be connected and assembled at multiple positions of the reflective lens, for example Figure 1 As shown, a plurality of fixed main bodies 2100 may have a large number of fixed assembly parts 2130 for assembling the reflective lens, so that the reflective lens can be connected to a plurality of fixed main bodies 2100 based on a large number of connection positions, further improving the assembly stability of the reflective lens.

[0052] The second bracket unit 2000 includes at least two fixed main bodies 2100, and the plurality of fixed main bodies 2100 can be assembled between the first supporting main body 1100 and the second supporting main body 1200 of the first bracket unit 1000 in a variety of arrangements. For example, in one embodiment, the second bracket unit 2000 may include two fixed main bodies 2100, and the two fixed main bodies 2100 are cross-connected between the first supporting main body 1100 and the second supporting main body 1200 of the first bracket unit 1000. Among them, among the two cross-connected fixed main bodies 2100, one of the fixed main bodies 2100 has a first embedding portion, and the other fixed main body 2100 has a second embedding portion, and the two fixed main bodies 2100 are mutually positioned and embedded through the first embedding portion and the second embedding portion.

[0053] The first engaging part and the second engaging part can be respectively provided with grooves and protrusions of matching structures, shapes, sizes, etc., to construct a mortise and tenon configuration, thereby maintaining the shape arrangement stability between the two fixed main bodies 2100 through the mutual engagement between the grooves and the protrusions, and preventing the two fixed main bodies 2100 from being separated from each other when subjected to unexpected forces. At the same time, the two fixed main bodies 2100 can also be provided with through holes at the positions where the first engaging part and the second engaging part are located, and then the two fixed main bodies 2100 are connected by means of threaded connection or pin connection.

[0054] In addition, in one embodiment, a plurality of fixing body members 2100 may be disposed parallel to each other between the first supporting body member 1100 and the second supporting body member 1200 of the first bracket unit 1000, for example Figures 4 to 6 As shown, the two fixing main bodies 2100 are arranged parallel to each other between the first supporting main body 1100 and the second supporting main body 1200 of the first bracket unit 1000, or as shown in FIG. Figures 7 to 9 As shown, three fixing body members 2100 are arranged parallel to each other between the first supporting body member 1100 and the second supporting body member 1200 of the first bracket unit 1000. Those skilled in the art can select a suitable number of fixing body members 2100 and a suitable arrangement to assemble all fixing body members 2100 according to actual needs, which is not limited here.

[0055] In one embodiment, the first supporting body 1100 may also be configured as a linear rod-shaped member, such as a column-shaped rod or a plate-shaped rod, etc., which is not limited here. A plurality of first joints 1110 may be provided on the first supporting body 1100, so that the first connecting portion 2110 of each fixed body 2100 may be connected to a first joint 1110 of the first supporting body 1100, and the connection between the first connecting portion 2110 and the first joint 1110 may be detachably connected based on at least one assembly method selected from the group consisting of a snap connection, a plug-in connection and a threaded connection. For example, the first connecting portion 2110 and the first combining portion may be provided with threaded holes for threading bolts, screws and other threaded members, or the first connecting portion 2110 and the first combining portion may be provided with protrusions and grooves that snap-fit ​​with each other, thereby realizing snap-fit ​​assembly between the two through the protrusions and the grooves, or the first connecting portion 2110 and the first combining portion may be provided with plug-in protrusions and plug-in through holes, thereby realizing plug-in assembly between the two through the plug-in protrusions and the plug-in through holes. Those skilled in the art may select any one of the above, or a combination of two or three of the above, to realize the detachable connection between the first connecting portion 2110 and the first combining portion, which is not limited here.

[0056] Similarly, the second supporting body 1200 may also be configured as a linear rod-shaped member, such as a column-shaped rod or a plate-shaped rod, etc., which is not limited here. A plurality of second joint parts 1210 may be provided on the second supporting main body 1200, so that the second connecting part 2120 of each fixed main body 2100 can be connected to a second joint part 1210 of the second supporting main body 1200, and the connection between the second connecting part 2120 and the second joint part 1210 can be detachably connected based on at least one assembly method selected from the group consisting of snap connection, plug connection and threaded connection. For example, the second connecting part 2120 and the second combining part may be provided with threaded holes for threading bolts, screws and other threaded parts, or the second connecting part 2120 and the second combining part may be provided with protrusions and grooves that snap-fit ​​with each other, thereby realizing snap-fit ​​assembly between the two through the protrusions and grooves, or the second connecting part 2120 and the second combining part may be provided with plug-in protrusions and plug-in through holes, thereby realizing plug-in assembly between the two through the plug-in protrusions and plug-in through holes. Those skilled in the art may choose any one of the above, or a combination of two or three at the same time to realize the detachable connection between the second connecting part 2120 and the second combining part, which is not limited here.

[0057] like Figure 1 , Figure 2As shown, in one embodiment, a first positioning element 1120 is provided on the first supporting body, and a second positioning element 1220 is provided on the second supporting body, and a positioning assembly space is formed between the first positioning element 1120 on the first supporting body and the second positioning element 1220 on the second supporting body, and the positioning assembly space is used to position and assemble the reflective lens. For example, the first positioning element 1120 and the second positioning element 1220 are configured as positioning plates, and a positioning step for positioning the edge of the reflective lens can be formed between the two positioning plates on the first supporting body and the second supporting body, respectively, so as to facilitate accurate positioning of the fitted reflective lens, thereby forming a positioning assembly space between the first positioning element 1120 and the second positioning element 1220.

[0058] Furthermore, a first fastening element 1130 is provided on the first positioning element 1120, at least a portion of which is configured as a flexible structure, and the first fastening element 1130 can be fixed to the first positioning element 1120 by means of threads, snap-fitting, etc., and the number of the first fastening elements 1130 can be set to one or more. A second fastening element 1230 is provided on the second positioning element 1220, at least a portion of which is configured as a flexible structure, and the second fastening element 1230 can be fixed to the second positioning element 1220 by means of threads, snap-fitting, etc., and the number of the second fastening elements 1230 can be set to one or more.

[0059] Therefore, after the reflective lens is assembled in the positioning assembly space formed above, the first buckling element 1130 can be limitedly abutted against the surface of the reflective lens, and at the same time, the second buckling element 1230 can also be limitedly abutted against the surface of the reflective lens after the reflective lens is assembled in the positioning assembly space formed above. Therefore, when the first buckling element 1130 and the second buckling element 1230 are respectively limitedly abutted against the two ends of the reflective lens, the reflective lens can be fixed in the positioning assembly space. Among them, the first buckling element 1130 and the second buckling element 1230 are both in contact with the reflective lens through their flexible structures.

[0060] In one of the embodiments, the bottom of the first snap-fitting element 1130 and the second snap-fitting element 1230 is provided with a threaded structure, and the top of the first snap-fitting element 1130 and the second snap-fitting element 1230 is provided with a structure similar to a hook. The first snap-fitting element 1130 and the second snap-fitting element 1230 clamp the reflective lens in place through nuts, washers, springs and other parts, further improving the fixing effect of the reflective lens and effectively preventing the reflective lens from shaking or falling off during the driving of the car.

[0061] As can be seen from the above, the first bracket unit 1000 and the second bracket unit 2000 in the above-mentioned reflective assembly bracket can be connected and assembled through the first support body 1100, the second support body 1200 and the plurality of fixed body members 2100. This mutually connected assembly method has a certain stability, which can effectively prevent the spliced ​​reflective assembly bracket from deformation, and provide a certain strength of support for the reflective lens. At the same time, the connection assembly form of the above-mentioned reflective assembly bracket can replace the traditional one-piece support fixing structure, and compared with the traditional one-piece injection-molded base, it can greatly save production materials and reduce production costs. Moreover, this reflective assembly bracket can also be quickly assembled and disassembled, and is easy to operate.

[0062] See also Figures 1 to 11 As shown, the present application provides a reflecting device, which includes the above-mentioned reflecting assembly bracket and a reflecting lens for reflection. The reflecting lens is arranged on the reflecting assembly bracket. The reflecting lens can be specifically designed to have a matching mirror curvature according to requirements and the curvature design of the reflecting assembly bracket.

[0063] In one embodiment, the reflection device includes a rotation adjustment device 3000, which is connected to the reflection assembly bracket and is used to adjust the pitch rotation angle of the reflection assembly bracket, thereby forming a small angle rotation of the reflection lens, thereby adjusting the height and clarity of the image. The reflection assembly bracket has a horizontal virtual reference line along the direction from the first support body 1100 to the second support body 1200 of the first bracket unit 1000, and the pitch rotation of the reflection assembly bracket is configured as a fixed-axis rotation with the horizontal virtual reference line as the fixed-axis rotation axis. The horizontal virtual reference line can be understood as follows Figure 1 , Figure 4 and Figure 7 A reference line is set in the left and right directions, and the horizontal virtual reference line can pass through the center of the reflection assembly bracket, thereby realizing the pitch rotation of the reflection assembly bracket along the center of the reflection assembly bracket.

[0064] Therefore, when the rotation adjustment device 3000 is disposed on the vehicle body, the rotation adjustment device 3000 can realize the pitch rotation control of the reflective assembly bracket through rotation control. Fig.11 As shown, the rotation adjustment device 3000 may include at least a base 3100, a gear set 3200 and a holding element 3300. The base 3100 can be used to connect to the vehicle body, and the gear set 3200 and the holding element 3300 are assembled on the base 3100. The user can manually control the rotation of the holding element 3300, thereby driving the gear set 3200 to realize rotation transmission. By connecting the output end of the gear set 3200 to the reflection assembly bracket, the pitch rotation control of the reflection assembly bracket can be achieved through gear transmission.

[0065] The gear set 3200 may include several gears with different diameters. For example, a small-diameter gear is driven to rotate the large-diameter gear connected thereto, thereby driving the corresponding gear to rotate, thereby adjusting the elevation angle and imaging position of the reflective assembly bracket and the reflective lens. By changing the ratio of the number of teeth of gears of different diameters, the input rotation speed can be converted into a larger torque and a smaller output rotation speed of the output shaft, so that the elevation angle of the reflective assembly bracket and the reflective lens can be fine-tuned. On the contrary, the torque required for the large-diameter gear to drive the small-diameter gear to rotate is greater. At the same time, there is friction between the gears and the installation parts. During the driving of the vehicle, the torque generated by the shaking of the vehicle is not enough to change the elevation angle of the reflective assembly bracket and the reflective lens.

[0066] In addition, the above-mentioned rotation adjustment device 3000 can also be transmitted through various transmission mechanisms such as connecting rod transmission mechanism, screw transmission mechanism, etc. as the transmission basis, and the holding element 3300 shown can also be replaced by an electric control drive device such as a motor to achieve electronically controlled pitch angle adjustment. Technical personnel in this field can choose a suitable method to construct the rotation adjustment device 3000 according to actual needs, and no limitation is made here.
