Description

Technical Field

[0001] The present disclosure relates to the field of vehicle-mounted display technology, and in particular to a HUD reflector mounting device. Background Art

[0002] Head-Up Display (HUD) technology was originally used in the aviation field to enhance flight safety by displaying flight data in the pilot's direct field of view to reduce the pilot's line of sight during operation. With the development of science and technology, this technology has been widely used in the automotive industry, providing drivers with an information display platform that can be seen without shifting their line of sight downward. The displayed content usually includes key driving information such as speed, navigation instructions, and engine speed.

[0003] Although HUD technology has brought many benefits to driving safety, its application in automobiles still faces some technical challenges, especially regarding the installation and stability of the reflector in the HUD system. In traditional designs, the HUD reflector is installed through a relatively fixed bracket structure. When the vehicle encounters bumpy roads during driving, this structure is prone to minor changes in the position of the reflector due to vibration, thereby affecting the stability and clarity of the display. In addition, the traditional reflector installation structure is often complex in design, which is not conducive to simplifying the production process and subsequent maintenance.

[0014] Furthermore, there is damping between at least one of the fixed connection member and the movable connection member and the connecting shaft.

[0015] Furthermore, the HUD reflector is in contact with the connecting shaft, and the connecting shaft has a damping effect on the rotation of the HUD reflector.

[0016] Furthermore, the damping rotation assembly also includes at least one first positioning portion and at least one second positioning portion, the first positioning portion is arranged on the surface of the movable connecting member, and the second positioning portion is arranged on the surface of the fixed connecting member.

[0017] Furthermore, at least one reflector positioning member is provided on the end surface of the HUD reflector facing the damping rotation assembly, and the first positioning portion cooperates with the reflector positioning member to align and assemble the movable connecting member with the HUD reflector; and

[0018] At least one support part positioning member is arranged on a side surface of the support part facing the damping rotation assembly, and the second positioning member cooperates with the support part positioning member to align and assemble the fixed connection member with the support part.

[0035] The present disclosure provides a HUD reflector mounting device, such as Figure 1-4 As shown, it includes a damping rotation assembly 1 for connecting a HUD reflector 2, and a support portion 4 for supporting the HUD reflector 2 and the damping rotation assembly 1. The damping rotation assembly 1 includes a fixed connection member 1.3, the fixed connection member 1.3 is fixed to the support portion 4, a connecting shaft 1.4, the connecting shaft 1.4 is connected to the fixed connection member 1.3, and a movable connection member 1.5, the movable connection member 1.5 is connected between the connecting shaft 1.4 and the HUD reflector 2 and can rotate around the connecting shaft 1.4. The damping rotation assembly 1 is configured to provide damped rotation.

[0036] The damping rotation assembly 1 disclosed in the present invention utilizes the damping characteristics to effectively suppress the vibration of the HUD reflector 2 in a dynamic environment, reduce the jitter of the HUD image, and improve the image clarity and stability. The structure design disclosed in the present invention is simple, the number of components is small, and it is easy to assemble and maintain.

[0037] In one embodiment of the present disclosure, Figure 1 As shown, the movable connecting member 1.5 is installed on the fixed connecting member 1.3 through the connecting shaft 1.4, and can rotate around the connecting shaft 1.4 relative to the fixed connecting member 1.3.

[0038] In one embodiment of the present disclosure, Figure 1 As shown, the fixed connecting member 1.3 includes a mounting plate extending parallel to the assembly surface and a connecting plate bent and extended upward, the surface of the mounting plate is flat, and the mounting plate is fixed to the support portion 4 by at least one fastener 3; the connecting plate is an upward bent and extended portion arranged on one side of the mounting plate, and a first through hole is provided on the connecting plate, and the connecting shaft 1.4 passes through the first through hole to assemble the movable connecting member 1.5 to the connecting plate.

[0039] In one embodiment of the present disclosure, Figure 1As shown, the connecting shaft 1.4 is a round rod or a cylindrical structure, which is arranged between the fixed connecting member 1.3 and the movable connecting member 1.5. The movable connecting member 1.5 can rotate around its axis. The movable connecting member 1.5 is a plate-like component with a second through hole in the center. The connecting shaft 1.4 passes through the first through hole and the second through hole. The movable connecting member 1.5 is installed on the fixed connecting member 1.3. The connecting shaft 1.4 also includes stop assemblies arranged at both ends thereof, and the stop assemblies are used to limit the axial sliding of the connecting shaft 1.4 along the through hole.

[0040] In other embodiments of the present disclosure, the main bodies of the fixed connector 1.5 and the movable connector 1.3 can be set to a rectangular plate or other geometric shapes to adapt to different HUD shells, and the shaft body of the connecting shaft 1.4 can also be connected to the stop assembly through a keyway, interference fit, welding structure, integrated design, thread and plug-in structure.

[0041] The movable connecting member 1.5 is installed on the fixed connecting member 1.3 through the connecting shaft 1.4, and the design of being rotatable around the connecting shaft 1.4 enables the HUD reflector 2 to be adjusted to different angles to accommodate drivers of different heights and sight lines. This adjustment capability enables the driver to clearly see the information displayed on the HUD without changing the sight focus during driving, thereby enhancing driving safety and comfort.

[0042] In one embodiment of the present disclosure, Figure 1 As shown, there is damping between at least one of the fixed connection member 1.3 and the movable connection member 1.5 and the connection shaft 1.4.

[0043] In the present disclosure, there is no restriction on the damping implementation method between the connecting shaft 1.4 and the fixed connecting member 1.3 and the movable connecting member 1.5. In one embodiment of the present disclosure, a damping material, such as rubber, is provided on the surface of the connecting shaft 1.4 to generate damping on the contact surface between the connecting shaft 1.4 and the movable connecting member 1.5 and the fixed connecting member 1.3.

[0044] The present disclosure does not impose any restrictions on the specific material of the connecting shaft 1.4, and a material that is wear-resistant, corrosion-resistant and has a certain load capacity is selected. In one embodiment of the present disclosure, the connecting shaft 1.4 can be made of carbon stainless steel, which can ensure a stable connection between the movable connecting member 1.5 and the fixed connecting member 1.3 in scenarios of bumps, humidity and long-term use.

[0045] In other embodiments of the present disclosure, the connecting shaft 1.4 may also provide friction damping by interference fit between the contact surfaces of the fixed connector 1.3 and the movable connector 1.5, or by providing a damping washer between the connecting shaft 1.4 and the contact surfaces of the fixed connector 1.3 and the movable connector 1.5.

[0046] The assembly method of the connecting shaft 1.4, the fixed connecting member 1.3 and the movable connecting member 1.5 absorbs the assembly tolerance inside the damping rotation assembly 1. When the angle of the HUD reflector 2 is adjusted, the motor drives the HUD reflector 2 to rotate, and the damping between the contact surface of at least one of the fixed connecting member 1.3 and the movable connecting member 1.5 and the connecting shaft 1.4 ensures the smooth rotation of the HUD reflector 2. After the motor stops rotating, the HUD reflector 2 is kept at the required angle position, thereby providing a stable and clear image display for the driver. This assembly method fully reduces the swing or noise caused by the imprecise fit between the components inside the damping rotation assembly 1, and improves the overall durability and safety of the HUD system.

[0047] In one embodiment of the present disclosure, Figure 2 As shown, the HUD reflector 2 is in contact with the connecting shaft 1.4, and the connecting shaft 1.4 has a damping effect on the rotation of the HUD reflector 2.

[0048] In one embodiment of the present disclosure, Figure 2 As shown, the end surface of the HUD reflector 2 facing the damping rotation component 1 contacts the connecting shaft 1.4 through the matching point 2.3, and damping exists between the contact surface of the connecting shaft 1.4 and the HUD reflector 2.

In one embodiment of the present disclosure, a silicone layer is provided between the contact surfaces of the HUD reflector 2 and the connecting shaft 1.4, and the silicone layer abuts against the matching point 2.3. The HUD reflector 2 is driven to rotate by a motor. The rotation of the HUD reflector 2 is smoother under the damping effect of the silicone layer, so that the HUD system can respond more stably to the driver's adjustment of the reflector position, and further reduce the vibration of the HUD reflector in a dynamic environment, thereby improving driving safety.

[0055] In one embodiment of the present disclosure, Figure 2 , Figure 3 As shown, the reflector positioning member 2.1 is a positioning column arranged at intervals on the end face of the HUD reflector 2 facing the damping rotation component 1, and the reflector positioning member 2.1 is connected to the first positioning portion 1.11, and the first positioning portion 1.11 forms a limit for the reflector positioning member 2.1, so that the HUD reflector 2 is aligned and assembled with the movable connecting member 1.5 while limiting the vibration of the HUD reflector 2, and the support portion positioning member 4.1 is a positioning column arranged on the surface of the support portion 4 facing the damping rotation component 1. The support portion positioning member 4.1 is connected to the second positioning portion 1.12, so that the fixed connecting member 1.3 is aligned and assembled with the support portion 4 while limiting the vibration of the fixed connecting member 1.3 in a dynamic environment, thereby ensuring the stable display of the HUD system image.
