Description

Technical Field

[0001] This utility model relates to the field of head-up display device processing technology, specifically a fixture. Background Technology

[0002] HUD stands for Head-Up Display, a type of head-up display device. A HUD consists of a PGU (Power Probe Unit) and two reflectors, a large and a small one. The large reflector is typically rotatable, allowing adjustment of the HUD's virtual image height to accommodate drivers of different heights. It also allows the large reflector to be rotated to shut off the HUD in case of backlighting, blocking sunlight from entering the PGU and preventing overheating and damage. Because the large reflector needs to rotate, a rotating assembly is located at its base. This assembly typically includes a motor and a gear assembly. The gear assembly is fixedly connected to the large reflector, and the motor's drive end meshes with the gear assembly to drive the large reflector's rotation.

[0003] The motor assembly typically includes a base, a motor, a spring, a screw, and a limiting plate. The motor, spring, and screw are assembled to form a first assembly. The first assembly is installed on the base, and the limiting plate is also installed on the base. After the first assembly and the base are assembled, and after the limiting plate and the base are assembled, they need to be locked with screws. Generally, this can be done by using a screw-locking device.

[0004] Since the locking of the first component and the base, and the locking of the limiting plate and the base are located in two different directions, the existing locking often requires manual intervention to adjust the direction to be locked of the motor component so that the screw locking operation can be performed at two angles, resulting in low assembly efficiency.

[0005] Therefore, this application proposes a fixture to solve the aforementioned problems. Utility Model Content

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0020] like Figure 6 As shown, the motor assembly of the HUD includes a base 101, a motor 102, a spring, a screw (not shown), and a limiting plate 103. The motor 102, spring, and screw are assembled to form a first assembly, which is mounted on the base 101. The limiting plate 103 is also mounted on the base 101. The screw (not shown) passes through the base 101 and is placed in a screw groove. Connecting plates 104 are provided on both sides of the motor 102, and the connecting plates 104 are attached to the sides of the base 101. The limiting plate 103 is a PCBA board, on which a position sensor and other electronic components are provided for detecting the rotation angle of the large reflector for limiting. The limiting plate 103 has a first screw hole 1031 to lock and fix the limiting plate 103 to the base 101. The connecting plate 104 has a second screw hole 1041 to lock and fix the first assembly to the base 101. The first screw hole 1031 is located in a first direction, and the second screw hole 1041 is located in a second direction. The first direction and the second direction are perpendicular.

[0021] This application provides a clamp for the HUD motor assembly described above, which fixes the motor assembly and automatically flips it. It works with a screw-locking device to lock the first component to the base 101 and the limiting plate 103 to the base 101. The screw-locking operation can be performed at two angles without manual intervention to adjust the direction to be locked of the motor assembly, thus improving assembly efficiency.

[0022] Please see Figure 1-5 The fixture provided in this application includes: a mounting component 1, a clamping assembly 2, and a driving assembly 3. The mounting component 1 includes a mounting plate 11 and a support platform 12, with the support platform 12 disposed on the mounting plate 11. The clamping assembly 2 is rotatably connected to the support platform 12 and is used to fix the motor assembly to be assembled. The driving assembly 3 is disposed on one side of the mounting component 1 and connected to the clamping assembly 2, and is used to provide the driving force for the clamping assembly 2 to rotate.

[0023] Specifically, the mounting plate 11 is installed on the workbench, which can be the tabletop of the screw-locking equipment or a corresponding work surface; no limitation is made here. In this embodiment, the workbench includes a base plate 20, which is slidably mounted on a slide rail (not shown). The base plate 20 is detachably connected to the mounting plate 11 to facilitate the replacement of different clamps, enabling the screw-locking equipment to be used for multiple purposes. The mounting plate 11 has multiple mounting holes, through which bolts or other fasteners are used to fix the mounting plate 11 to the base plate 20, and the support platform 12 is also fixed to the mounting plate 11 through the mounting holes.

[0024] In some embodiments, the clamping assembly 2 includes a cover plate 21 and a placement seat 22; the placement seat 22 has a placement groove 221 for placing the motor assembly; the cover plate 21 is flipped to engage with the placement seat 22 for limiting and fixing. One end of the cover plate 21 is rotatably connected to the placement seat 22, allowing the cover plate 21 to be flipped open and closed relative to the placement seat 22.

[0025] Specifically, since the clamping component 2 can be flipped, it has a first working state and a second working state. In the first working state, the placement seat 22 is placed horizontally on the support platform 12, and the screw-locking device can lock the first screw hole 1031, that is, screw-lock and fix the limiting plate 103 and the base 101. In the second working state, the drive component 3 drives the placement seat 22 to flip 90°. At this time, the placement seat 22 is placed vertically on the support platform 12, and the screw-locking device can lock the second screw hole 1041, that is, screw-lock and fix the first component and the base 101. This achieves locking of the motor component of the HUD in two directions without the need for manual flipping, thus improving assembly efficiency.

[0026] It should be noted that the placement slot 221 is matched with the shape of the motor assembly to be assembled. That is, the placement slot 221 includes a first receiving slot 2211 and a second receiving slot 2212. The first receiving slot 2211 is used to match the shape of the motor, and the second receiving slot 2212 is used to match the shape of the base 101.

[0027] In some embodiments, the cover plate 21 is provided with a first connecting portion, and the placement seat 22 is provided with a second connecting portion corresponding to the first connecting portion, and the first connecting portion and the second connecting portion are adsorbed together.

[0028] Specifically, the first connecting part is disposed on the side of the cover plate 21 near the first receiving groove 2211, and the second connecting part is disposed correspondingly to the first connecting part. The first connecting part includes a connecting block 211, on which a first magnetic element 212 is provided, and the second connecting part includes a second magnetic element 222, and the first magnetic element 212 and the second magnetic element 222 are attracted and connected.

[0029] It should be noted that the first connecting part may include a first magnetic element 212, and the second connecting part may include a connecting block 211, with a second magnetic element 222 on the connecting block 211. Alternatively, both the first and second connecting parts may include a connecting block 211, with the first magnetic element 212 and the second magnetic element 222 respectively disposed on the two connecting blocks 211. When the cover plate 21 is closed, the first magnetic element 212 and the second magnetic element 222 on the two connecting blocks 211 match and attract each other. The attraction method of the first and second connecting parts can be varied as needed and is not limited here.

[0030] Furthermore, after the motor assembly to be locked is placed in the placement slot 221 and the cover plate 21 is closed, the connecting block 211 is located on one side of the middle part of the motor 102. There are gaps between the two sides of the connecting block 211 and the placement seat 22. These gaps expose the second screw hole 1041, so that after the clamping component 2 drives the motor assembly to be locked to flip, the first component and the base 101 can be locked from the gaps on both sides.

[0031] In some embodiments, in order to prevent the cover plate 21 from being unstable when it is closed with the placement seat 22, the cover plate 21 is also provided with a third connecting part, and the placement seat 22 is provided with a fourth connecting part corresponding to the third connecting part, and the third connecting part and the fourth connecting part are adsorbed together.

[0032] Specifically, the third connecting part is located on the side of the cover plate 21 away from the motor, and the fourth connecting part is correspondingly provided to the third connecting part. The third connecting part includes a third magnetic element 213, and the fourth connecting part includes a fourth magnetic element 223. The third magnetic element 213 and the fourth magnetic element 223 are connected by adsorption.

[0033] In some embodiments, the cover plate 21 has a first through hole 214, which connects to the placement groove 221.

[0034] Specifically, the motor assembly to be locked is placed in the placement slot 221, and the first through hole 214 corresponds to the first screw hole 1031 on the limiting plate 103, so that the screw can lock the limiting plate 103 and the base 101 from the first through hole 214.

[0035] In some embodiments, the cover plate 21 further includes a protective pad 215, which is disposed on the side of the cover plate 21 near the placement seat 22, and the protective pad 215 does not interfere with the first through hole 214.

[0036] Specifically, the protective pad 215 is used to reduce the contact pressure of the cover plate 21 on the motor assembly to be locked, and to prevent the cover plate 21 from damaging the motor assembly. The protective pad 215 is set on the cover plate 21 and will not interfere with the first through hole 214. Of course, the protective pad 215 will not affect the adsorption connection between the cover plate 21 and the placement seat 22.

[0037] In some embodiments, the drive assembly 3 includes a drive element 31 and a drive shaft 32, the drive shaft 32 driving the placement seat 22 to rotate the placement seat 22.

[0038] It should be noted that the driving component 31 includes a cylinder, the driving end of which is connected to the driving shaft 32. Alternatively, the driving component 31 may also include a motor, the driving end of which is connected to the driving shaft 32. The driving component 31 provides rotational driving force, causing the driving shaft 32 to rotate the placement base 22.

[0039] In some embodiments, the support platform 12 further includes a mounting shaft 121, and the placement seat 22 is provided with connecting ears 224 on both sides; the connecting ears 224 are sleeved on the mounting shaft 121, and the end of the mounting shaft 121 near the drive shaft 32 is connected to the drive shaft 32.

[0040] Specifically, the mounting shaft 121 can be a long shaft that passes through the support platform 12 and protrudes from both ends of the support platform 12, allowing the mounting shaft 121 to rotate within the support platform 12. The two protruding ends of the mounting shaft 121 are fixedly connected to the connecting ears 224. The end of the mounting shaft 121 closest to the drive shaft 32 is fixedly connected to the drive shaft 32, thereby enabling the drive component 31 to drive the drive shaft 32 to rotate, and the rotation of the drive shaft 32 to cause the placement seat 22 to flip. Alternatively, the mounting shaft 121 can be provided with two short shafts, each rotatably connected to one side of the support platform 12. Both mounting shafts 121 are fixedly connected to the connecting ears 224, and the mounting shaft 121 closest to the drive shaft 32 is also fixedly connected to the drive shaft 32, thereby enabling the drive component 31 to drive the drive shaft 32 to rotate, and the rotation of the drive shaft 32 to cause the placement seat 22 to flip. The mounting shaft 121 can be modified according to actual needs and is not limited here.

[0041] In some embodiments, the clamp further includes a limiting rod 4, which is vertically disposed on the mounting plate 11 and is used to limit the rotation range of the placement seat 22.

[0042] Specifically, when the clamping assembly 2 is in the second working state, the limiting rod 4 is in contact with the cover plate 21; when the clamping assembly 2 is in the first working state, the limiting rod 4 is not in contact with the clamping assembly 2 in the first working state.

[0043] Furthermore, if the 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 relation to the specification. The significance or implied number of the indicated technical features is not specified. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.
