Figure 4 A schematic diagram of the structure of a drive module provided in an embodiment of the present application.

[0040] The present application embodiment provides a driving module 100, combined with Figure 1-Figure 3 As shown, optionally, the driving module 100 provided in the embodiment of the present application is applied to the head-up display device 200. The head-up display device 200 is a device that uses the optical reflection principle to project the driving information XXX and the like through the windshield 300 into the field of vision of the driver 400, which can make the driver 400 more focused, which is conducive to improving the driving safety. In the head-up display device 200, the driving module 100 is used to adjust the angle of the lens M1 so as to adjust the position where the driving information XXX is projected onto the windshield 300. In the system of the entire driving module 100, optionally, the lens M1 is a curved mirror, which can be used to reflect the light generated by the image generating unit. In addition, there is a curved mirror support frame 200A to ensure the rigidity of the curved mirror. The curved mirror support frame 200A is connected to the driving module 100. The driving module 100 can transmit power to the curved mirror support frame 200A, so that it keeps a certain center rotation around the rotation axis 200B, thereby adjusting the angle and position of the curved mirror.

[0041] Combination Figure 4 As shown, the embodiment of the present application provides a driving module 100 including a sliding bracket 10 and a connecting portion 20, wherein the sliding bracket 10 includes a first limiting structure 10A and a second limiting structure 10B arranged opposite to each other along a first direction X1. The connecting portion 20 is used to connect with the lens M1, and optionally, the lens M1 is a curved mirror. The connecting portion 20 includes a curved mirror bracket protruding structure 20A, and the curved mirror bracket protruding structure 20A is located between the first limiting structure 10A and the second limiting structure 10B, and the connecting portion 20 is connected to the curved mirror support frame 200A. When the sliding bracket 10 slides, it drives the curved mirror bracket protrusion structure 20A to move between the first limiting structure 10A and the second limiting structure 10B. When the angle and position of the lens M1 need to be adjusted, the sliding bracket 10 moves in a direction parallel to the first direction X1, and the curved mirror bracket protrusion structure 20A is between the first limiting structure 10A and the second limiting structure 10B, forming a clamping effect on the curved mirror bracket protrusion structure 20A, so that when the sliding bracket 10 slides, it also drives the curved mirror bracket protrusion structure 20A to move. When the curved mirror bracket protrusion structure 20A moves, it drives the connecting part 20 and the curved mirror support frame 200A connected to the connecting part 20 to move around the rotation axis 200B, thereby adjusting the angle of the lens M1.

[0042] It should be noted that the driving module 100 also includes a motor 30, which can be a stepping motor. The motor 30 is connected to the screw rod 40, and the motor 30 can control the screw rod 40 to rotate. When the screw rod 40 rotates, the slider 401 installed on the screw rod 40 starts to slide, and the slider 401 is engaged with the sliding bracket 10, and the sliding bracket 10 and the screw rod 30 are detachably connected. Therefore, when the screw rod 40 rotates, the movement of the slider 401 also drives the sliding bracket 10 to move along the first direction X1. When the sliding bracket 10 moves, the first limiting structure 10A or the second limiting structure 10B in the sliding bracket 10 forms a thrust on the curved mirror bracket protrusion structure 20A, so that the curved mirror bracket protrusion structure 20A generates movement along the first direction X1. The curved mirror support protrusion structure 20A is connected to the connection part 20, and the connection part 20 is fixedly connected to the curved mirror support frame 200A. The rotation axis 200B is a structure that does not produce displacement. It is fixedly connected to the curved mirror support frame 200A. When the curved mirror support protrusion structure 20A moves in the first direction X1, the curved mirror support protrusion structure 20A will also move in the direction H perpendicular to the plane where the sliding bracket 10 is located, thereby driving the curved mirror support frame 200A to make a circular motion around the rotation axis 200B, and further driving the lens M1 to make a circular motion around the rotation axis 200B, and finally changing the position and angle of the virtual image on the windshield. At this time, the curved mirror support protrusion structure 20A also drives the module 100 to also include a limit device 50. The limit device 50 is prepared on one side of the sliding bracket 10 in the first direction X1. Optionally, the limit device 50 is detachably connected to the motor 30. The contact sensing device of the limit device 50 is located on one side of the limit device 50 close to the sliding bracket 10 in the first direction X1, and contacts with the components on the sliding bracket 10. The limit device 50 is used to sense the position of the sliding bracket 10 so that the driving module 100 can better control the moving distance of the sliding bracket 10 along the first direction X1, and control the rotation angle of the lens M1 accordingly.

[0043] In the related art, the first limiting structure and the second limiting structure can be structures integrated with the sliding bracket. When assembling the driving module, the curved mirror bracket protrusion structure needs to be placed between the first limiting structure and the second limiting structure, so that the curved mirror bracket protrusion structure always moves between the two limiting structures. Due to the tolerance of the preparation process, for example, in the diameter of the curved mirror bracket protrusion structure, it is difficult to achieve the exact match between the diameter of the curved mirror bracket protrusion structure and the distance between the first limiting structure and the second limiting structure, so that it is difficult to achieve the effect that the curved mirror bracket protrusion structure is always in contact with the surface of the first limiting structure and the second limiting structure. This easily leads to the fact that when the curved mirror bracket protrusion structure stays at a certain angle, the first limiting structure and the second limiting structure cannot be well engaged and fixed to it, so that there is a gap between the curved mirror bracket protrusion structure and the first limiting structure and / or the second limiting structure, so that when the car encounters bumps during driving, the curved mirror bracket protrusion structure will shake, thereby driving the curved mirror to shake, and then causing the picture projected by the head-up display device on the windshield to shake, which is not conducive to picture stability and ensuring the driving safety of the driver.

[0044] In order to improve the fixing effect of the driving module 100 on the curved mirror support protruding structure 20A, eliminate the gap between the curved mirror support protruding structure 20A and the first limiting structure 10A and the second limiting structure 10B due to the manufacturing tolerance, and reduce the shaking of the curved mirror support protruding structure 20A during use. The embodiment of the present application proposes that at least one of the first limiting structure 10A and the second limiting structure 10B is a retractable structure. Optionally, one of the first limiting structure 10A and the second limiting structure 10B is a fixed structure and the other is a retractable structure. It is beneficial to make at least one of the first limiting structure 10A and the second limiting structure 10B retractable to follow the movement of the curved mirror support protruding structure 20A, so as to achieve the effect of always contacting with the curved mirror support protruding structure 20A, thereby limiting the curved mirror support protruding structure 20A to contact with both the first limiting structure 10A and the second limiting structure 10B, and eliminating the gap between the curved mirror support protruding structure 20A and the first limiting structure 10A and the second limiting structure 10B. It should be noted that at least one of the first limiting structure 10A and the second limiting structure 10B is a retractable structure, and its retractable direction is parallel to the first direction X1. Optionally, the first limiting structure 10A is a retractable structure, and the first limiting structure 10A can move along the first direction X1.

[0045] In the embodiment of the present application, at least one of the first limiting structure 10A and the second limiting structure 10B is set as a retractable structure, which is conducive to making the curved mirror support protrusion structure 20A always in contact with the first limiting structure 10A and the second limiting structure 10B when moving, so that the first limiting structure 10A and the second limiting structure 10B clamp the curved mirror support protrusion structure 20A, reduce the shaking space of the curved mirror support protrusion structure 20A between the first limiting structure 10A and the second limiting structure 10B, thereby improving the fixing effect of the driving module 100 on the curved mirror support protrusion structure 20A. Therefore, it is conducive to improving the stability of the curved mirror support protrusion structure 20A, improving the image stability of the head-up display device in the process of projecting driving information, and reducing safety hazards during driving. In addition, by using at least one of the first limiting structure 10A and the second limiting structure 10B as a retractable structure to eliminate the gap caused by the tolerance between the limiting structure and the curved mirror bracket protrusion structure 20A, it is beneficial to reduce the difficulty of the process preparation when preparing the driving module 100 and improve the preparation efficiency of the driving module 100.

[0046] In one embodiment of the present application, reference Figure 4 As shown, the first limiting structure 10A is set as a retractable structure, and the sliding bracket 10 includes a main body 10C, and the first limiting structure 10A is detachably connected to the main body 10C. The first limiting structure 10A is a retractable structure. When the sliding bracket 10 moves in a direction parallel to the first direction X1, the first limiting structure 10A and the second limiting structure 10B included therein also move in the first direction X1, and the curved mirror bracket protrusion structure 20A located between the first limiting structure 10A and the second limiting structure 10B also moves in a direction parallel to the first direction X1. In the embodiment of the present application, the first limiting structure 10A has an initial squeezing force in the direction of the curved mirror bracket protrusion structure 20A, thereby fixing the curved mirror bracket protrusion structure 20A. Taking the case where the sliding bracket 10 moves along the second limiting structure 10B pointing to the first limiting structure 10A in the first direction X1 as an example, during the movement of the curved mirror bracket protruding structure 20A, the second limiting structure 10B gives a thrust to the curved mirror bracket protruding structure 20A, and correspondingly, the curved mirror bracket protruding structure 20A gives a thrust to the first limiting structure 10A. Since the first limiting structure 10A is a retractable structure, the first limiting structure 10A can resist the thrust of the curved mirror bracket protruding structure 20A to squeeze it, thereby fixing the curved mirror bracket protruding structure 20A. It should be noted that during the movement of the curved mirror bracket protruding structure 20A, the squeezing force of the first limiting structure 10A on the curved mirror bracket protruding structure 20A changes, but it can still play a fixing role on the curved mirror bracket protruding structure 20A.

[0047] In the embodiment of the present application, the first limiting structure 10A is set as a retractable structure. When the curved mirror bracket protruding structure 20A is installed with the sliding bracket 10, optionally, the diameter of the curved mirror bracket protruding structure 20A is set to be larger than the initial distance between the first limiting structure 10A and the second limiting structure 10B, so that the curved mirror bracket protruding structure 20A can be inserted between the first limiting structure 10A and the second limiting structure 10B and contact both of them. At this time, the first limiting structure 10A is a retractable structure. When the curved mirror bracket protruding structure 20A is installed, the first limiting structure 10A can be retracted along the first direction X1 so that the distance between the first limiting structure 10A and the second limiting structure 10B is equal to the diameter of the curved mirror bracket protruding structure 20A, and the first limiting structure 10A has the potential energy of retraction, and this potential energy also forms an extrusion effect on the curved mirror bracket protruding structure 20A. In addition, the detachable connection between the first limiting structure 10A and the main body 10C is provided, which is conducive to improving the mobility of the first limiting structure 10A and ensuring good contact between the first limiting structure 10A and the curved mirror bracket protrusion structure 20A. In addition, it is conducive to improving the structural diversity of the sliding bracket, and the structure of the first limiting structure 10A can be adaptively adjusted when applied to different curved mirror bracket protrusion structures 20A, thereby reducing the preparation cost of the driving module 100. In addition, it is conducive to reducing the difficulty of preparing the sliding bracket 10 when a retractable structure is provided, and improving the manufacturability of the sliding bracket 10.

[0048] In one embodiment of the present application, continue to refer to Figure 4 As shown, the second limiting structure 10B and the main body 10C are provided as an integral structure.

[0049] In the embodiment of the present application, the second limiting structure 10B and the main body 10C are provided as an integral structure, which is beneficial to reducing the preparation process flow of the sliding bracket 10, improving the structural performance of the second limiting structure 10B, and improving the limiting effect of the second limiting structure 10B on the curved mirror bracket protruding structure 20A.

[0050] Figure 5 A schematic diagram of the structure of another driving module provided in an embodiment of the present application.

[0051] In one embodiment of the present application, Figure 5 As shown, the first limiting structure 10A includes a column 10A1, and the main body 10C includes an opening 10C1. The column 10A1 extends in the first direction X1 and is embedded in the opening 10C1.

[0052] In the embodiment of the present application, the connection between the first limiting structure 10A and the main body 10C is realized by the engagement of the column 10A1 and the opening 10C1. The column 10A1 extends in the first direction X1 and is embedded in the opening 10C1. When the curved mirror support protrusion structure 20A forms an extrusion force on the first limiting structure 10A along the first direction X1, the first limiting structure 10A can be extended and retracted along the first direction X1. Optionally, a column limiting structure 10A2 is provided on the outside of the main body 10C including the opening 10C1, so that the column limiting structure 10A2 is buckled at one end of the column 10A1, and the diameter of the column limiting structure 10A2 is greater than the diameter of the opening 10C1. It should be noted that when the first limiting structure 10A is extended and retracted along the first direction X1, the column 10A1 included therein is also extended and retracted along the first direction X1, and there is a situation where the column 10A1 extends in the first direction X1 toward the side away from the second limiting structure 10B. The column limiting structure 10A2 is buckled on one end of the column 10A1, rather than being fixed on the main body 10C, which is conducive to ensuring that the column 10A1 is a movable structure in the opening 10C1, and is conducive to preventing the column 10A1 from moving toward the second limiting structure 10B, and causing the end of the column 10A1 away from the second limiting structure 10B to fall off the opening 10C, causing the column 10A1 structure to fail. Optionally, the column limiting structure 10A2 is nut-shaped.

[0053] Figure 6 A schematic diagram of the structure of another driving module provided in an embodiment of the present application is shown in FIG. Figure 7 A schematic diagram of state changes of a first buckle and a second buckle provided in an embodiment of the present application, Figure 8 A schematic diagram of the structure of another driving module provided in an embodiment of the present application is shown in FIG. Fig. 9 A method provided in the embodiment of the present application Figure 8 Schematic diagram of the cross section along the A-A' direction.

[0054] In one embodiment of the present application, Figure 6 As shown, the first limiting structure 10A includes a first buckle 10A3, and the main body 10C includes a second buckle 10C2, and the first buckle 10A3 is used to engage with the second buckle 10C2.

[0055] like Figure 6 As shown, the first buckle 10A3 and the second buckle 10C2 are arranged to engage with each other along a direction H perpendicular to the plane where the sliding bracket 10 is located. Figure 6 1 is a side view of the driving module. For example, when the first buckle 10A3 and the second buckle 10C2 are initially mounted and engaged, the first buckle 10A3 and the second buckle 10C2 can abut against each other's side walls in a direction parallel to the first direction X1. Figure 7 As shown, Figure 7As shown in Figure (a), when the curved mirror bracket protrusion structure 20A is installed between the first limiting structure 10A and the second limiting structure 10B, the curved mirror bracket protrusion structure 20A pushes the first buckle 10A3 of the first limiting structure 10A in a direction parallel to the first direction X1 to the side away from the second limiting structure 10B. At this time, the first buckle 10A3 and the second buckle 10C2 include a gap W along the first direction X1, that is, the end of the first buckle 10A3 does not completely abut against the side wall of the second buckle 10C2 in a direction parallel to the first direction X1, which is conducive to the first buckle 10A3 having a moving space to counteract the thrust of the curved mirror bracket protrusion structure 20A to squeeze it, thereby squeezing and fixing the curved mirror bracket protrusion structure 20A. In the embodiment of the present application, the state in which the first buckle 10A3 does not completely abut against the side wall of the second buckle 10C2 in a direction parallel to the first direction X1, and the second buckle 10C2 does not completely abut against the side wall of the first buckle 10A3 in a direction parallel to the first direction X1, and the state in which the sliding bracket 10 is in contact with the limiting device 50 is the initial state when the curved mirror bracket protruding structure 20A is placed between the first limiting structure 10A and the second limiting structure 10B; Figure 7 As shown in FIG. (b), when the curved mirror support protrusion structure 20A is displaced along the first direction X1, the curved mirror support protrusion structure 20A gives a thrust to the first limiting structure 10A, and the first buckle 10A3 is also thrusted accordingly. Since the first limiting structure 10A is a retractable structure, during the movement of the curved mirror support protrusion structure 20A parallel to the first direction X1, the thrust of the curved mirror support protrusion structure 20A on the first limiting structure 20A is not constant, so the width of the gap W included in the first buckle 10A3 and the second buckle 10C3 along the direction parallel to the first direction X1 will also adaptively produce some changes and Figure 7 There are some differences in the initial state shown in Figure (a).

[0056] Optionally, combined Figure 8 , Fig. 9As shown, the first buckle 10A3 and the second buckle 10C2 are arranged to engage in a direction parallel to the first direction X1. Optionally, the second buckle 10C2 may be arranged to be a hole-shaped structure, the second buckle 10C2 is inserted into the first buckle 10A3, and a gap W is provided between the side of the first buckle 10A3 away from the second limiting structure 10B in the first direction X1 and the side wall of the second buckle 10C2. This is advantageous in that when the curved mirror support protruding structure 20A is installed between the first limiting structure 10A and the second limiting structure 10B, when the curved mirror support protruding structure 20A pushes the first buckle 10A3 of the first limiting structure 10A in a direction parallel to the first direction X1 toward the side away from the second limiting structure 10B, the first limiting structure 10A together with the first buckle 10A3 has a space for expansion and contraction toward the side away from the second limiting structure 10B in a direction parallel to the first direction X1.

[0057] Further, when the curved mirror support protrusion structure 20A is installed between the first limiting structure 10A and the second limiting structure 10B, the curved mirror support protrusion structure 20A gives a thrust to the first limiting structure 20A, and the first limiting structure 10A together with the first buckle 10A3 has a side extension parallel to the first direction X1 away from the second limiting structure 10B, so that there is a certain gap W between the side walls of the first buckle 10A3 and the second buckle 10C2 in the direction parallel to the first direction X1. Optionally, the curved mirror support protrusion structure 20A is installed in the first limiting structure 10A and the second limiting structure 10B, and the sliding bracket 10 is in contact with the limiting device 50, which is the initial state. At this time, the gap W between the side wall of the first buckle 10A3 on the side facing the second limiting structure 10B in the first direction X1 and the side wall of the second buckle 10C2 is less than or equal to the gap W between the side wall of the first buckle 10A3 on the side away from the second limiting structure 10B in the first direction X1 and the side wall of the second buckle 10C2.

[0059] In one embodiment of the present application, Fig.10 , Fig.11 As shown, the second buckle 10C2 is arranged outside the main body 10C. Optionally, the first buckle 10A3 and the second buckle 10C2 are engaged along the first direction X1. As described in the above embodiment, the first buckle 10A3 can be arranged as a hole-shaped structure so that the second buckle 10C2 is buckled into the first buckle 10A3, or the second buckle 10C2 can be arranged as a hole-shaped structure so that the first buckle 10A3 is buckled into the second buckle 10C2.

[0060] In the embodiment of the present application, the second buckle 10C2 is arranged outside the main body 10C, which is conducive to reducing the difficulty of the snap connection between the first buckle 10A3 and the second buckle 10C2, and the degree of observability during assembly is high, which is easy to assemble. In addition, other structures can be arranged inside the main body 10C, and the second buckle 10C2 is arranged outside the main body 10C, which is conducive to increasing the structural space that can be prepared inside the main body 10C.

[0061] In one embodiment of the present application, continue to refer to Figure 8 , Fig. 9 As shown, the second buckle 10C2 can be arranged on the inner side of the main body 10C, which is beneficial to avoid the situation where the first limiting structure 10A including the first buckle 10A3 part needs to be prepared on the outer side of the main body 10C, and is beneficial to reduce the space occupied by the first limiting structure 10A on the outer side of the main body 10C, thereby avoiding increasing the overall structure of the sliding bracket 10.

[0062] Fig.12 A schematic diagram of the structure of another driving module provided in an embodiment of the present application is shown in FIG. Fig.13 A method provided in the embodiment of the present application Fig.12 Partial top view of the middle area E1, Fig.14 A top view of a driving module provided in an embodiment of the present application, Fig.15 A schematic diagram of the structure of another driving module provided in an embodiment of the present application is shown in FIG. Fig.16 A top view of another driving module provided in an embodiment of the present application.

[0063] In one embodiment of the present application, Figure 12-Figure 15 As shown, an elastic component 10D is included between the first limiting structure 10A and the main body 10C, and the elastic component 10D is used to enable the first limiting structure 10A to extend in the first direction X1. The first limiting structure 10A is a rigid structure detachably connected to the main body 10C, and the main body 10C is a fixed structure integrated with the sliding bracket 10. The elastic component 10D is arranged between the first limiting structure 10A and the main body 10C to provide a driving force for the first limiting structure 10A to extend and retract along the first direction X1.

[0064] The elastic component 10D is assembled between the first limiting structure 10A and the main body 10C, and the elastic force direction of the elastic component 10D is parallel to the first direction X1. Fig.12 , Fig.14As shown, when the elastic component 10D is compressed by the first limiting structure 10A, the elastic force direction generated by the elastic component 10D is parallel to the first direction X1 and points from the right to the left. When the curved mirror support protrusion structure 20A is placed between the first limiting structure 10A and the second limiting structure 10B, the curved mirror support protrusion structure 20A gives a certain extrusion force to the first limiting structure 10A, so that the first limiting structure 10A moves in the direction of the elastic component 10D, so that the elastic group 10D is squeezed, and the elastic component 10D has the potential energy of rebound, which continuously gives a thrust to the first limiting structure 10A, and then the first limiting structure 10A and the second limiting structure 10B can maintain a good clamping of the curved mirror support protrusion structure 20A, which is conducive to making the curved mirror support protrusion structure 20A always in contact with the first limiting structure 10A and the second limiting structure 10B, and limiting the shaking of the curved mirror support protrusion structure 20A.

[0065] like Figure 12-14 As shown, when the first limiting structure 10A includes a column 10A1 and the main body 10C includes an opening 10C1, the elastic component 10D can be set as a helical spring. Optionally, the spring is nested on the column 10A1, which is conducive to fixing the elastic component 10D, and the elastic component 10D is retractable along the first direction X1. One end of the elastic component 10D in the first direction X1 contacts the first limiting structure 10A, and the other end contacts the main body 10C. In addition, the diameter of the elastic component 10D is larger than the diameter of the opening 10C1 on the main body 10C, which is conducive to preventing the elastic component 10D nested on the column 10A1 from extending from the opening 10C1 when the column 10A1 extends from the opening 10C1 toward the side away from the second limiting structure 10B, but restricting the elastic component 10D to the side of the opening 10C1 facing the second limiting structure 10B, thereby ensuring the function of the elastic component 10D.

[0066] In combination with the above-mentioned setting of the diameter of the curved mirror support protrusion structure 20A to be greater than the initial distance between the first limiting structure 10A and the second limiting structure 10B. Exemplarily, when the spring is nested on the column 10A1 and the curved mirror support protrusion structure 20A is not installed between the first limiting structure 10A and the second limiting structure 10B, the spring nested on the column 10A1 is in a state of no compression deformation or slight compression deformation, and the side of the spring facing the second limiting structure 10B contacts the surface of the first limiting structure 10A, and the side of the spring away from the second limiting structure 10B contacts the surface of the main body 10C. When the curved mirror support protrusion structure 20A is inserted between the first limiting structure 10A and the second limiting structure 10B, since the diameter of the curved mirror support protrusion structure 20A is greater than the initial distance between the first limiting structure 10A and the second limiting structure 10B, the curved mirror support protrusion structure 20A forms a thrust on the first limiting structure 10A, and the first limiting structure 10A is displaced toward the side away from the second limiting structure 10B in a direction parallel to the first direction X1. The column 10A1 also moves toward the side away from the second limiting structure 10B in a direction parallel to the first direction X1 and at least partially extends out of the opening 10C1, and the size of the spring embedded in the column 10A1 is greater than the size of the opening 10C1, and the spring can be confined to the side of the opening 10C1 facing the second limiting structure 10B. Therefore, along the direction parallel to the first direction X1, the space between the first limiting structure 10A and the main body 10C is compressed, so that the spring is squeezed by the first limiting structure 10A and the main body 10C in the direction parallel to the first direction X1, forming a certain degree of compression. The spring has a rebound potential energy in a compressed state, and the rebound potential energy of the spring acts on the first limiting structure 10A so that the first limiting structure 10A has a resistance force to resist the thrust of the curved mirror support protrusion structure 20A toward the second limiting structure 10B, thereby achieving a fixing effect on the curved mirror support protrusion structure 20A. When the curved mirror support protrusion structure 20A moves along the direction parallel to the first direction X1, the thrust of the curved mirror support protrusion structure 20A on the first limiting structure 10A is not constant, but the first limiting structure 10A always has the ability to contact and fix the curved mirror support protrusion structure 20A under the action of the elastic potential energy of the spring.

[0067] Or, if Fig.15 , Fig.16As shown, the first limiting structure 10A is provided to include a first buckle 10A3, and the main body 10C includes a second buckle 10C2. Optionally, the elastic component 10D is provided to be a spring. The spring contacts the side wall of the first limiting structure 10A along one surface of the first direction X1, and the spring faces the side structure of the main body 10C in the first direction X1 against the main body 10C structure. The spring can be wavy, similar to when the elastic component 10D is a spring. When the elastic component 10D is a spring, when the curved mirror support protruding structure 20A forms a thrust on the first limiting structure 10A, the space distance between the first limiting structure 10A and the main body 10C is compressed, so that the spring is also compressed. At this time, the spring also has the potential energy of rebound to act on the first limiting structure 10A, and the first limiting structure 10A is ready to move to one side of the second limiting structure 10B, so as to achieve the first limiting structure 10A and the curved mirror support protruding structure 20A to fit and fix the curved mirror support protruding structure 20A. Optionally, the elastic component 10D is a wavy structure. The wavy structure of the elastic component 10D is conducive to better dispersing stress when the elastic component 10D is compressed, so that when the elastic component 10D has the rebound condition, it also has a good buffering effect, reducing the impact of the rebound impact force on the first limiting structure 10A. In addition, the wavy elastic component 10D also has the advantages of long service life, small size, convenient installation, high stability, etc.

[0068] Fig.17 A schematic diagram of the structure of another driving module provided in an embodiment of the present application.

[0069] Or, for example, Fig.17As shown, the first limiting structure 10A includes a first buckle 10A3 and a second buckle 10C2 that are engaged in a direction H perpendicular to the plane where the sliding bracket 10 is located, and the elastic component 10D that matches is a spring. The spring is arranged in a direction parallel to the first direction X1, and is located between the first buckle 10A3 and the main body 10C. Optionally, a column 10A1 is prepared on the first buckle 10A3, and an opening 10C1 and a column limiting structure 10A2 are prepared on the main body 10C accordingly, which is conducive to improving the fixing effect of the spring. Combined with the working mode of the elastic component 10D when it is a spring in the above content, when the spring has the potential energy of rebound, the first limiting structure 10A is prepared to move toward the second limiting structure 10B. Because the existence of the curved mirror bracket convex structure 20A forms a certain restriction on the movement of the first limiting structure 10A, the effect of fixing the curved mirror bracket convex structure 20A is achieved. However, during the driving of the car, for example, when there is a more severe bump, there may be a moment when the thrust of the curved mirror bracket protrusion structure 20A on the first limiting structure 10A is relatively small. In this case, it is possible that under the action of the potential energy of the spring rebound, the first limiting structure 10A moves a greater distance toward the side of the second limiting structure 10B; more seriously, if the potential energy of the spring rebound is relatively large, it may also act on the first limiting structure 10A and squeeze the curved mirror bracket protrusion structure 20A between the first limiting structure 10A and the second limiting structure 10B, thereby causing the fixing effect of the lens M1 to fail, and further causing the head-up display device 200 to be unable to properly transmit the driving information XXX to the driver's 400 field of view. Therefore, in the embodiment of the present application, the spring can be used in combination with the first buckle 10A3 and the second buckle 10C2, because: in combination with the working description of the first buckle 10A3 and the second buckle 10C2 in the above content, when the curved mirror support protrusion structure 20A is installed in the first limiting structure 10A and the second limiting structure 10B, the first buckle 10A3 and the second buckle 10C2 include a gap W along the first direction X1, which reserves a certain space for the movement of the first limiting structure 10A parallel to the first direction X1, but because the second buckle 10C2 is a fixed structure, the movable range of the first limiting structure 10A is also limited. When the potential energy of the spring rebound acts on the first limiting structure 10A, even if the first limiting structure 10A is displaced in the direction toward the second limiting structure 10B, the first limiting structure 10A will also be pulled by the second buckle 10C2 under the action of the first buckle 10A3 and the second buckle 10C2, so that the first limiting structure 10A will not produce an unexpected movement. Moreover, the design of the gap W and other dimensions can prevent the potential energy of the spring rebound from being completely released, further ensuring the movement range of the first limiting structure 10A and improving the reliability of fixing the first limiting structure 10A and the second limiting structure 10B to the curved mirror bracket protrusion structure 20A.

[0070] In addition, if Fig.12 , Fig.15 As shown, optionally, the main body 10C includes a side wall that at least partially surrounds the elastic component 10D. An incision 10C3 can be prepared on the side wall of the main body 10C close to the elastic component 10D, and part of the side wall is removed, so that when viewed from the side of the driving module 100, part of the elastic component 10D and the first limiting structure 10A are not blocked by the main body 10C, so that part of the elastic component 10D and the first limiting structure 10A can be directly observed, which is beneficial to improve the visualization when assembling the first limiting structure 10A and the elastic component 10D, reduce the difficulty of assembly, and also reduce the difficulty of maintenance.

[0071] In one embodiment of the present application, continue to refer to Figure 12-16 As shown, the elastic component 10D is one of a spring, a spring, and an elastic block.

[0072] In one embodiment of the present application, Fig.16 As shown, the contact between the first limiting structure 10A and the elastic component 10D is line contact.

[0073] In the embodiment of the present application, the elastic component 10D is arranged to be in line contact with the first limiting structure 10A, which is beneficial to increasing the contact range between the elastic component 10D and the first limiting structure 10A, thereby improving the fixation between the elastic component 10D and the first limiting structure 10A, and is beneficial to ensuring the retractable ability of the first limiting structure 10A and the fixing ability of the curved mirror bracket protruding structure 20A.

[0074] Fig.18 A method provided in the embodiment of the present application Fig.12 A side view of the middle area E2 along the first direction, Fig.19 A method provided in the embodiment of the present application Fig.15 A side view of the middle area E3 along the first direction.

[0075] In one embodiment of the present application, in combination with 12, Fig.15 , Figure 18-19As shown, the surface of the first limiting structure 10A facing the elastic component 10D in the first direction X1 includes a first area 10AA and a second area 10AB symmetrically distributed in the second direction X2, and the contact areas of the first area 10AA and the second area 10AB with the elastic component 10D are equal. The second direction X2 and the first direction X1 are located in the same plane and the second direction X2 intersects with the first direction X1. The elastic component 10D is arranged to contact the surface of the first limiting structure 10A in two parts, and the contact areas of the elastic component 10D and the first area 10AA and the second area 10AB are equal, so that the elastic force applied by the elastic component 10D to the first limiting structure 10A is relatively uniform, avoiding the seesaw effect of the first limiting structure 10A.

[0076] In the embodiment of the present application, the contact areas of the first area 10AA and the second area 10AB of the first limiting structure 10A and the elastic component 10D are set to be equal, which is beneficial to balancing the force on the first limiting structure 10A, reducing the force difference between the first area 10AA and the second area 10AB, improving the stability of the first limiting structure 10A, avoiding the seesaw effect of the first limiting structure 10A, and reducing the risk of deterioration in the fixing performance of the curved mirror bracket protrusion structure 20A.

[0077] In one embodiment of the present application, continue to refer to Figure 18-19 As shown, the positions in the first area 10AA and the second area 10AB that contact the elastic component 10D are symmetrical.

[0078] In the embodiment of the present application, the positions in the first area 10AA and the second area 10AB that contact the elastic component 10D are symmetrical, which is beneficial to improving the uniformity of the elastic force applied by the first limiting structure 10A to the first area 10AA and the second area 10AB, and avoiding a large offset in the position where the elastic component 10D applies the elastic force to the first limiting structure 10A, thereby causing the risk of the first limiting structure 10A being skewed.

[0079] In one embodiment of the present application, continue to refer to Fig.16 As shown, the elastic component 10D has an M-shaped structure. Moreover, the M-shaped structure is a symmetrical structure. Setting the elastic component 10D to have an M-shaped structure is conducive to achieving a solution in which the contact areas of the elastic component 10D and the first area 10AA and the second area 10AB are equal and the contact positions are symmetrical. Moreover, the M-shaped structure has good stability, which is conducive to stabilizing the elastic component 10D and the first limiting structure 10A.

[0080] Fig. 20 A dynamic schematic diagram of a sliding bracket along a first direction provided in an embodiment of the present application, Fig.21 A schematic diagram of the structure of another driving module provided in an embodiment of the present application is shown in FIG. Fig. 22A schematic diagram of the structure of another driving module provided in an embodiment of the present application.

[0081] In one embodiment of the present application, Fig. 20 As shown, when the sliding bracket 10 slides along the first direction X1 to the first side X11, optionally, the first side is located in the direction of the sliding bracket 10 pointing from the second limiting structure 10B to the first limiting structure 10A in the first direction X1. Fig. 20 As shown in FIG. 2 (a), the height of the curved mirror support protrusion structure 20A in the initial state is close to the center; Fig. 20 As shown in FIG. (b), the curved mirror support protrusion structure 20A is connected to the connection part 20, and the connection part 20 is fixedly connected to the curved mirror support frame 200A. The rotation axis 200B is a structure that does not generate displacement, and is fixedly connected to the curved mirror support frame 200A. Taking the sliding bracket 10 sliding along the first direction X1 to the first side X11 as an example, when the curved mirror support protrusion structure 20A moves in the first direction X1, the curved mirror support protrusion structure 20A will also move in the direction H perpendicular to the plane where the sliding bracket 10 is located, thereby driving the curved mirror support frame 200A to make a circular motion around the rotation axis 200B, and further driving the lens M1 to make a circular motion around the rotation axis 200B, and finally changing the position and angle of the virtual image on the windshield. The curved mirror support protrusion structure 20A is driven to displace between the first limiting structure 10A and the second limiting structure 10B in a direction away from the bottom of the first limiting structure 10A and the second limiting structure 10B. In this way, when the curved mirror support protrusion structure 20A moves greatly in the direction away from the bottom of the first limiting structure 10A and the second limiting structure 10B and approaches the vertex of the limiting structure, there is a risk that the curved mirror support protrusion structure 20A will slide out between the first limiting structure 10A and the second limiting structure 10B. Therefore, along the first direction X1, when the curved mirror support protrusion structure 20A moves toward the first limiting structure 10A or the second limiting structure 10B and is lifted, in order to prevent the curved mirror support protrusion structure 20A from sliding out between the first limiting structure 10A and the second limiting structure 10B, the following solution is proposed:

[0082] like Fig.21As shown, the first limiting structure 10A is located on the first side of the second limiting structure 10B in the first direction X1, and the height of the first limiting structure 10A in the direction perpendicular to the driving module 100 is greater than the height of the second limiting structure 10B in the direction perpendicular to the driving module 100. This is suitable for when the protruding structure 20A of the curved mirror bracket moves toward the side where the first limiting structure 10A is located in the first direction X1 and is lifted, which is beneficial to use the first limiting structure 10A to prevent the protruding structure 20A of the curved mirror bracket from sliding out between the first limiting structure 10A and the second limiting structure 10B, ensuring that the clamping effect of the first limiting structure 10A and the second limiting structure 10B on the curved mirror bracket 20A is stable. Or, as Fig. 22 As shown, the second limiting structure 10B is located on the first side of the first limiting structure 10A in the first direction X1, and the height of the second limiting structure 10B in the direction perpendicular to the driving module 100 is greater than the height of the first limiting structure 10A in the direction perpendicular to the driving module 100. This is suitable for when the curved mirror support protrusion structure 20A moves toward the side where the second limiting structure 10B is located in the first direction X1 and is lifted, which is conducive to using the second limiting structure 10A to prevent the curved mirror support protrusion structure 20A from sliding out between the first limiting structure 10A and the second limiting structure 10B, ensuring that the first limiting structure 10A and the second limiting structure 10B have a stable clamping effect on the curved mirror support 20A.

[0083] In one embodiment of the present application, the shape of the curved mirror support protruding structure 20A is spherical, cylindrical, or hemispherical, and the surface of the curved mirror support protruding structure 20A in contact with the first limiting structure 10A and the second limiting structure 10B is a curved surface.

[0084] In the embodiment of the present application, the curved mirror support protrusion structure 20A is set to be one of spherical, cylindrical, and hemispherical, which is conducive to the installation of the curved mirror support protrusion structure 20A, and is conducive to making it rollable, so that it is suitable for the movement between the first limiting structure 10A and the second limiting structure 10B when it is lifted away from the bottom. In addition, the surface of the curved mirror support protrusion structure 20A in contact with the first limiting structure 10A and the second limiting structure 10B is set to be a curved surface, which is conducive to making the curved mirror support protrusion structure 20A move more smoothly between the first limiting structure 10A and the second limiting structure 10B, and is conducive to avoiding the situation where the curved mirror support protrusion structure 20A is stuck or blocked when moving between the first limiting structure 10A and the second limiting structure 10B.

[0085] In one embodiment of the present application, the first limiting structure 10A, the second limiting structure 10B, and the curved mirror support protruding structure 20A are made of the same material, which is conducive to avoiding friction between the curved mirror support protruding structure 20A and the first limiting structure 10A and the second limiting structure 10B when the materials are different, especially when plastic and metal are used. After long-term use, wear and tear are likely to occur, which leads to the risk of gaps between the curved mirror support protruding structure 20A and the first limiting structure 10A and the second limiting structure 10B. Therefore, the curved mirror support protruding structure 20A and the first limiting structure 10A and the second limiting structure 10B are made of the same material, which is conducive to reducing the risk of component wear, improving the fixing stability of the first limiting structure 10A and the second limiting structure 10B to the curved mirror support protruding structure 20A, improving the stability of the driving module 100, and ensuring driving safety performance. Optionally, the materials of the first limiting structure 10A, the second limiting structure 10B, and the curved mirror support protruding structure 20A are all plastic or metal.

[0086] The present application embodiment provides a head-up display device 200, and further reference is made to Figure 3 As shown, the head-up display device 200 includes the driving module 100 provided in the above embodiment.

[0087] In the head-up display device 200, at least one of the first limiting structure 10A and the second limiting structure 10B is set as a retractable structure, which is conducive to making the curved mirror support protrusion structure 20A always in contact with the first limiting structure 10A and the second limiting structure 10B when moving, so that the first limiting structure 10A and the second limiting structure 10B clamp the curved mirror support protrusion structure 20A, reduce the shaking space of the curved mirror support protrusion structure 20A between the first limiting structure 10A and the second limiting structure 10B, thereby improving the fixing effect of the driving module 100 on the curved mirror support protrusion structure 20A. Therefore, it is conducive to improving the stability of the curved mirror support protrusion structure 20A, improving the image stability of the head-up display device in the process of projecting driving information, and reducing safety hazards during driving. In addition, by using at least one of the first limiting structure 10A and the second limiting structure 10B as a retractable structure to eliminate the gap caused by the tolerance between the limiting structure and the curved mirror bracket protrusion structure 20A, it is beneficial to reduce the difficulty of the process preparation when preparing the driving module 100 and improve the preparation efficiency of the driving module 100.

[0088] In one embodiment of the present application, Figure 3 As shown, the head-up display device 200 also includes:

[0089] The image generating unit 200C is used to generate driving information XXX.

[0090] The plane reflective mirror 200D is used to reflect the driving information of the image generating unit 200C to the lens M1 driven by the driving module 100 , and the lens M1 is used to reflect the driving information XXX to the windshield 300 . Figure 3 The dotted line between the image generation unit 200C, the plane reflector 200D, the windshield 300 , and the driver 400 is the reflection path of the light under the action of the head-up display device 200 .

[0091] After the driving information XXX is reflected to the windshield 300, the windshield 300 is used to reflect the light to the eyes of the driver 400, so that the driver 400 can see the driving information XXX in front of his line of sight, effectively avoiding the driver 400 from lowering his head or changing the direction of his line of sight when viewing the driving information XXX, avoiding distracting the driver 400's attention, and improving driving safety.

[0092] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application shall be included in the scope of protection of the present application.
