[0002] HUD, or Head-Up Display, is a display technology that projects key information onto the driver's line of sight, allowing them to access information without looking down. Its core components include an image generation unit (PGU) and a reflector. Specifically, the PGU emits image light that is projected onto the reflector, which then reflects and amplifies the light before projecting the image onto the windshield. Reflectors typically consist of a large and a small mirror. The large mirror often has a rotating drive mechanism to adjust its position, allowing the screen height to be adapted to different drivers.

[0003] The rotary drive structure includes a motor assembly, gears, and other components. The gears are connected to the large reflector. The motor assembly includes a motor, a spring, and a screw.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] The motor assembly of the HUD includes a motor 101, a spring 102, and a screw 103. In the assembled motor assembly, the output shaft of the motor 101 is connected to the screw 103. The spring 102 is sleeved on the output shaft of the motor 101 and is located between the motor 101 and the screw 103 to reduce the lateral clearance between the motor 101 and the screw 103.

[0028] Firstly, this application provides a HUD assembly fixture, applied to the aforementioned HUD motor assembly, see [link to relevant documentation]. Figures 1-4 This utility model provides a HUD assembly fixture including a base plate 1, a motor positioning component 2, and a screw moving component 3; the motor positioning component 2 is used to place the motor 101 and the spring piece 103;

[0029] The screw moving part 3 includes a screw positioning part and a moving part. The screw positioning part is used to at least partially place the screw, and the moving part is used to drive the screw positioning part to translate so that the screw is assembled with the motor.

[0030] Specifically, after the spring piece 102 is sleeved on the output shaft of the motor 101, the motor 101 and the spring piece 102 are placed on the motor positioning member 2 respectively, and the screw 103 is placed at the screw positioning part. The moving part drives the screw positioning part to move horizontally a certain distance. During the translation process, the screw positioning part pushes the screw 103 close to and inserts it into the output shaft of the motor 101.

[0031] In some embodiments, the motor positioning component 2 includes a loading seat 21 disposed on the working surface of the base plate 1; one end of the loading seat 21 is provided with a motor placement slot 22 for placing the motor 101, and the other end is provided with a spring piece placement slot 23 for at least partially supporting the spring piece 102.

[0032] Specifically, the spring 102 is L-shaped, meaning it has a short side and a long side. The short side of the spring 102 is fitted onto the output shaft of the motor 101 to form a first component. The motor 101 in the first component is placed in the motor placement slot 22. Correspondingly, the long side of the spring 102 is located in the spring placement slot 23 to achieve the placement and positioning of the first component.

[0033] In some embodiments, the screw positioning part includes a platform 31, the platform 31 is provided with a screw placement groove 311 for at least partially placing the screw 103, and a connecting plate 312 is provided at one end of the platform 31 away from the motor positioning member 2, wherein the screw placement groove 311 is located between the motor positioning member 2 and the connecting plate 312.

[0034] Specifically, the shelf 31 and the connecting plate 312 can be integrally formed. Of course, the shelf 31 and the connecting plate 312 can also be manufactured separately and fixedly connected by welding, bolts, etc., which is not limited here. The end of the screw placement groove 311 near the motor positioning member 2 is open, that is, after the screw 103 is located in the screw placement groove 311, its end can extend out of the screw placement groove 311 to facilitate the assembly of the screw 103 and the motor 101.

[0035] In some embodiments, the connecting plate 312 is connected to the drive end of the moving part, so that the moving part control screw placement slot 311 is close to and away from the motor positioning member.

[0036] Specifically, the connecting plate 312 has an L-shaped structure, that is, the connecting plate 312 is divided into a vertically arranged first part and a second part that intersects the first part perpendicularly. The side of the first part is connected to the shelf 31, and the side of the second part is connected to the driving end of the moving part, so as to connect the shelf 31 and the moving part through the connecting plate 312.

[0037] In some embodiments, the moving part includes a slide rail 32, a slider 33, and a driving member; the slide rail 32 is located on the base plate 1; the slider 33 is used to support the screw positioning part and transmit the power of the driving member, and is slidably disposed on the slide rail 32; the connecting plate 312 is fixed on the slider 33; the driving end of the driving member passes through the slider 33 and is connected to the connecting plate 312, and is used to push and pull the screw positioning part.

[0038] Specifically, the slide rail 32 is mounted on the base plate 1, and its moving direction is matched with the direction in which the screw 103 and the motor 101 are to be installed. The sliding member 33 is connected to the slide rail 32 through a sliding groove, and a longitudinal limiting structure is provided at the connection between the slide rail 32 and the sliding member 33 so that the sliding member 33 can only move horizontally along the slide rail. The longitudinal limiting structure can use a limiting groove (not shown) and a limiting block. For example, a limiting block can be provided on the side of the slide rail 32, and a limiting groove can be provided in the sliding groove of the sliding member 33 to cooperate with the limiting block, thereby limiting the movement. Of course, other methods can also be used, which are not limited here.

[0039] The sliding member 33 can generally be set as a plate-shaped structure, which is vertically arranged, with its bottom connected to the slide rail 32, and its side near the shelf 31 connected to the second side of the connecting plate 312 to connect the shelf 31 to the moving part.

[0040] In some embodiments, the driving component includes a base 34, a linear moving part, and a power part. The power part controls the screw positioning part to translate along the slide rail direction through the linear moving part. The base 34 is disposed on the base plate 1 and is used to support the linear moving part and the power part.

[0041] Specifically, the power unit includes a first connecting rod 35, a second connecting rod 36, and a power assembly 37 that are rotatably connected; the first end of the first connecting rod 35 is rotatably connected to the base 34, and the second end of the first connecting rod 35 is rotatably connected to the first end of the second connecting rod 36; the second end of the second connecting rod 36 is rotatably connected to the linear motion unit; wherein the second end of the first connecting rod 35 is also connected to the power assembly 37.

[0042] The linear moving part includes a power rod 38 and a threaded post 39; one end of the power rod 38 is threaded onto the threaded post 39, and the other end of the power rod 38 is connected to the second end of the connecting rod 36; wherein, the end of the threaded post 39 near the power rod 38 is threaded with a threaded cap 391, and the end of the threaded post 39 away from the power rod 38 is provided with a bolt head 392; the driving end of the threaded post 39 passes through the sliding member 33, and the threaded cap 391 is used to fix the threaded post 39 onto the sliding member 33. The threaded cap 391 is located between the sliding member 33 and the power rod 38, and the bolt head 392 is located between the connecting plate 312 and the sliding member 33.

[0043] The sliding member 10 has a fixing groove through which the threaded post 39 passes. The bolt head 392 and the threaded cap 391 are located on both sides of the sliding member 33 to lock the power rod 38 to the sliding member 33. When the power assembly 37 rotates, it drives the first connecting rod 35 to rotate, and the first connecting rod 35 drives the second connecting rod 36 to rotate, forming a horizontal thrust to push the power rod 38, thereby driving the sliding member 33 to move horizontally along the slide rail 32. Since the threaded post 39 and the threaded cap 391 lock the platform 31 to the sliding member 33, the platform 31 moves with the sliding member 33, ultimately achieving the purpose of driving the screw 103 to move.

[0044] In some embodiments, the linear moving part further includes a guide 341, which is fixedly connected to the base 34. The guide 341 is sleeved on the outer periphery of the power rod 38 for translating the power rod 38 within the guide 341.

[0045] Specifically, the power rod 38 has a cylindrical structure, and the guide 341 has an annular sleeve structure. The power rod 38 passes through the inside of the guide 341 sleeve so that the power rod can move horizontally along the guide 341.

[0046] In some embodiments, the power assembly 37 includes a handle, and the second end of the first connecting rod 35 is fixedly connected to the handle. When the user rotates the handle, the handle drives the first connecting rod 35 to rotate, thereby realizing the rotation of the second connecting rod 36, which generates a horizontal thrust to push the power rod 38. Each time the handle is turned, the assembly of one screw 103, motor 101, and spring 102 can be completed, improving assembly efficiency and ensuring normal subsequent use. Turning the handle in the opposite direction will drive the first connecting rod 35 and the second connecting rod 36 to move in the opposite direction. The second connecting rod 36 drives the power rod 38 and the sliding member to move and reset, so that the shelf 12 moves to the right and resets. The user takes out the assembled motor assembly, completing one assembly.

[0047] Secondly, embodiments of this application also provide a HUD assembly fixture, such as... Figure 5 Based on the first aspect, the base plate 1 is also provided with a vertical plate 26, which is located outside the loading seat 21. A connecting rod 27 is rotatably provided on the vertical plate 26, and a limiting roller 28 is rotatably provided at the end of the connecting rod 27. A baffle 29 is provided on the left side of the connecting rod 27 on the side wall of the vertical plate 26. In use, the limiting roller 28 is rotated to the lowest point, and the lowest point of the limiting roller 28 coincides with the highest point of the screw 103 in the platform 31. From the moment the screw 103 just contacts the output shaft until the screw 103 is fully inserted into the output shaft, the limiting roller 28 is always restricted above the screw 103. The friction between the screw 103 and the limiting roller 28 will drive the limiting roller 28 to rotate. However, under the action of the baffle 29, the connecting rod 27 will not rotate towards the output shaft, so as to prevent the end of the screw 103 near the output shaft of the motor 101 from tilting upward under the action of the thrust, and to ensure smooth insertion.

[0048] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.

[0049] It should be noted that if the utility model embodiment involves directional indicators such as up and down, the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture as shown in the figure. If the specific posture changes, the directional indicators will also change accordingly.

[0050] Furthermore, the meaning of "and / or" throughout the text includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or a solution that simultaneously satisfies A and B. Additionally, if the utility model embodiments involve descriptions such as "first," "second," etc., these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" or "second" can explicitly or implicitly include at least one of those features. Furthermore, "multiple" refers to two or more.

[0051] Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of a person skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection of the utility model.
