[0002] Augmented reality head-up display device is the combination of AR augmented reality technology and HUD head-up display function, which superimposes computer-generated virtual information in three-dimensional road environment, and the visual effects match the real road elements. It not only has a larger field of view and a longer imaging distance, but also provides more abundant and intuitive information display. It allows drivers to obtain important information such as vehicle condition, navigation system content, vehicle ecological service information and pedestrian warning on the windshield without looking down. The important performance parameters of augmented reality head-up display device, such as running stability, efficiency and service life, are affected by load torque, and real-time load torque during angle adjustment operation needs to be concerned and analyzed.

[0003] Currently, there are mainly three types of arrangements for the electromechanical system of augmented reality head-up display devices on the market: the first type is to place the transmission mechanism on the left / right side of the main mirror mechanism. In this arrangement, the transmission part is arranged close to the side of the main mirror system, and the overall electromechanical system design is compact, saving vertical space occupied by the whole system, and allowing for a higher main mirror in the same space. The second type is to place the transmission mechanism at the bottom of the main mirror mechanism. In this arrangement, the transmission part is arranged close to the bottom of the main mirror system, and the overall electromechanical system design is compact, saving horizontal space occupied by the whole system, and allowing for a longer main mirror in the same space. The third type is to place the transmission mechanism at the back of the main mirror mechanism. In this arrangement, the worm gear (actually a helical gear) is installed integrally with the main mirror system, and the worm, motor and anti-backlash parts are arranged in sequence at the back of the main mirror system. The overall electromechanical system design is compact, saving front and rear space occupied by the whole system, and allowing for a thicker main mirror in the same space. In the prior art, different test devices are needed for analyzing the load characteristics of augmented reality head-up display devices for different electromechanical system arrangements. When testing augmented reality head-up display devices with multiple electromechanical system arrangements, multiple test devices that adapt to different electromechanical system arrangements are needed, which has poor adaptability. Currently, there is no universal test device that adapts to different electromechanical system arrangements of augmented reality head-up display devices. UTILITY MODEL CONTENT

[0038] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0039] It should be noted that the terms "include" and "have" and any variations thereof in the embodiments of the present application and the drawings are intended to cover non-exclusive inclusion. For example, a series of structures are included, which are not limited to the listed structures, but can optionally further include structures not listed, or can optionally further include other components inherent to the structures.

[0040] The embodiments of the present application disclose a general testing device for the load torque of an electromechanical system of an augmented reality head-up display device, which is used for measuring the load torque of the electromechanical system in real time during the angle adjustment operation of the electromechanical system. The following will be described in detail.

[0041] Figure 1 A general testing device for the load torque of an electromechanical system of an augmented reality head-up display device is shown. As shown in Figure 1 The general testing device for the load torque of the electromechanical system of the augmented reality head-up display device comprises a pose adjustment system 1, a fixed support system 2 and an adjustment testing system 3. The pose adjustment system 1 is used for simulating the real vehicle attitude, so that the general testing device for the load torque of the electromechanical system of the augmented reality head-up display device obtains real-time testing data consistent with the real vehicle installation of the augmented reality head-up display device. The fixed support system 2 is used for supporting and fixing the electromechanical system of the augmented reality head-up display device, and the adjustment testing system 3 is mainly used for sensor adjustment and torque testing.

[0042] Specifically, as shown in Figure 1 The pose adjustment system 1 is not only used for simulating the real vehicle attitude, but also serves as the base of the entire fixed support system 2. The fixed support system 2 is arranged on the pose adjustment system 1, and the pose adjustment system 1 provides the fixed support system 2 with the rotational motion freedom degrees around the X-axis direction, the Y-axis direction and the Z-axis direction, so as to realize the three-axis rotation. The X-axis direction, the Y-axis direction and the Z-axis direction are perpendicular to each other. It should be noted that the Z-axis direction is the direction perpendicular to the horizontal ground, and in addition, the perpendicularity in the present application is not absolute perpendicularity, but can be 90°±10°.

[0043] In some embodiments, as shown in Figure 1As shown, the pose adjustment system 1 includes a bottom support frame 11, a first rotary motor 12, a U-shaped support frame 13, a second rotary motor 14, a frame-shaped support frame 15, and a third rotary motor (not shown in the figure).

The first rotary motor 12 is arranged on the bottom support frame 11, and the rotating shaft of the first rotary motor 12 extends along the Z-axis direction. The rotating shaft of the first rotary motor 12 is connected to the middle of the horizontal section 131 of the U-shaped support frame 13. The first rotary motor 12 provides the U-shaped support frame 13 with a rotational motion freedom degree around the Z-axis direction, i.e., the pose adjustment system 1 provides the fixed support system 2 with a rotational motion freedom degree around the Z-axis direction through the first rotary motor 12. The frame-shaped support frame 15 is arranged between the two vertical sections 132 of the U-shaped support frame 13 through the second rotary motor 14. The second rotary motor 14 provides the frame-shaped support frame 15 with a rotational motion freedom degree around the X-axis direction, i.e., the pose adjustment system 1 provides the fixed support system 2 with a rotational motion freedom degree around the X-axis direction through the second rotary motor 14. The fixed support system 2 is arranged in the frame-shaped support frame 15 through the third rotary motor. The third rotary motor provides the fixed support system 2 with a rotational motion freedom degree around the Y-axis direction, i.e., the pose adjustment system 1 provides the fixed support system 2 with a rotational motion freedom degree around the Y-axis direction through the third rotary motor. In the specific implementation process, the bottom support frame 11, the U-shaped support frame 13, and the frame-shaped support frame 15 in the pose adjustment system 1 are spliced by aluminum profile frames. The whole adopts a frame structure, is nested layer by layer, and is arranged symmetrically. Not only can the first rotary motor 12, the second rotary motor 14, and the third rotary motor realize three-axis rotation, but also the bearing capacity is high, the stability is good, and the adjustment precision is high.

The main mirror mechanism fixing module 22 and the transmission mechanism fixing module 23 are both arranged on the first support module 21. The main mirror mechanism fixing module 22 is used to fix and support the main mirror mechanism 4 of the augmented reality head-up display device, and the transmission mechanism fixing module 23 is used to fix and support the transmission mechanism 5 of the augmented reality head-up display device. In addition, the first support module 21 can adjust the setting positions of the main mirror mechanism fixing module 22 and the transmission mechanism fixing module 23 according to different electromechanical system arrangements. The first support module 21 adjusts the height of the main mirror mechanism fixing module 22 in the Z-axis direction to adapt to different fixed heights, and adjusts the positions of the transmission mechanism fixing module 23 in the X-axis direction and the Y-axis direction to meet the fixing requirements of the bottom of the transmission mechanism 5 under different assembly sizes.

[0046] Further, as Figure 4As shown, the first support module 21 further comprises a first fixed top plate 217, a first screw rod assembly 218, a first linear guide rail 219 and a first sliding block 2101. Both ends of the first fixed top plate 217 are fixedly installed on the middle part of the first horizontal long rod 212 and the second horizontal long rod 213, and the first fixed top plate 217 and the first fixed bottom plate 216 jointly constitute a fixed support structure of the first screw rod assembly 218. Through the setting of the first fixed top plate 217, the verticality of the entire screw rod assembly is ensured from the top and the bottom, thereby ensuring the accuracy of the height adjustment function of the first support module 21. In addition, such a design can also ensure that the overall structure of the first support module 21 will not affect the subsequent operation of the primary mirror mechanism fixing module 22 for fixing the primary mirror mechanism. Both ends of the first screw rod assembly 218 are arranged on the first fixed top plate 217 and the first fixed bottom plate 216, respectively. In addition, the inner side surfaces of the two first vertical support rods 211 on the second side and the fourth side are respectively provided with a first linear guide rail 219, and each first linear guide rail 219 is provided with a first sliding block 2101.

In this embodiment, the sensor support 317 is commonly supported by the second nut 3131 and the second sliding block 316.

Then, the height of the main mirror assembly fixing part 222 is greater than the sum of the height of the electromechanical system, the height of the convex pad 231 and the height of the base fixing part 232 by adjusting the position of the first lead screw assembly 218 of the fixed support system 2 and the first sliding block 2101 on the first linear guide rail 219, and the appropriate position of the transmission mechanism fixing module 23 is fixed in the horizontal plane of the first fixed bottom plate 216 according to the layout of the electromechanical system of the augmented reality head-up display device. After that, the base part of the electromechanical system of the augmented reality head-up display device to be tested can be fixed on the transmission mechanism fixing module 23, and the main mirror mechanism 4 is fixed on the main mirror mechanism fixing module 22 according to the installation features.

It needs to be ensured that the shaft center of the adapter shaft 35 is aligned with the shaft center of the transmission mechanism 5 in the horizontal plane, and then the position of the second lead screw assembly 313 and the second sliding block 316 on the second linear guide rail 315 is adjusted to keep the shaft center of the adapter shaft 35 consistent with the height of the shaft center of the transmission mechanism 5. The adapter shaft 35 needs to be inserted into the original motor position of the transmission mechanism 5, and the original motor is placed on the sensor bracket 317 through the motor bracket 36. Then, the pose adjustment system 1 is adjusted to simulate the real vehicle attitude. Finally, the motor wire harness, sensor wire harness and data acquisition equipment are connected, and the electromechanical load torque of the augmented reality head-up display device can be collected in real time.
