Description

Technical Field

[0001] This utility model relates to the field of vehicle component technology, and in particular to a vehicle-mounted HUD sunlight focusing resistance testing device. Background Technology

[0002] When sunlight backflow occurs, the light spot converges to a certain position inside the HUD. The light power is concentrated in this small area through the lens, resulting in a sharp increase in light power density. In addition, the heat effect causes the part of the light spot to heat up, and the temperature rise is positively correlated with the light spot power density.

[0003] The internal components of a HUD (such as diffuser films, light shields, and freeform mirrors) are mostly made of PC material, which is prone to deformation and melting under high temperatures. For film-type components, depending on the magnitude and distribution of temperature rise, it can cause varying degrees of image distortion, film damage, high-temperature breakdown, or even localized melting. When the temperature of a freeform mirror is too high, there is a risk of film cracking and peeling, affecting the overall optical performance of the HUD. Therefore, although the conditions for sunlight backflow to occur are quite demanding, once it happens, the damage is extremely serious.

[0004] The HUD sunlight focusing resistance test system is an effective means of testing the thermal reliability of HUD under the intensity of sunlight radiation. The test system requires adapting the HUD and windshield to the position of the light source and fixing it in the area where the sunlight converges on the diffuser film or freeform mirror with the highest temperature rise after it is incident. It also provides feedback on the operation of the HUD in normal temperature or high temperature environment. At the same time, it detects the changes in appearance and the changes in the overall optical performance after the sun is exposed for a certain period of time. The structural rigidity and the accuracy of the fixed position must be guaranteed.

[0005] In existing HUD sunlight focusing resistance testing systems, the design is generally based directly on the actual vehicle position. However, due to manufacturing errors and deformation in the actual testing system, the final test system state will deviate from the actual vehicle installation state. In other words, existing HUD sunlight focusing resistance testing systems cannot accurately match the positions of the windshield and HUD based on the sunlight source, making it difficult for the light spot focused on the HUD to maintain consistency with the theoretical light spot state.

Detailed Implementation

[0061] The challenge of existing HUD sunlight focusing test systems lies in how to accurately match the positions of the HUD and the windshield according to the sunlight source in order to simulate the precise position under the actual vehicle condition and accurately achieve the same sunlight focusing position as the actual vehicle condition. The vehicle-mounted HUD sunlight focusing resistance test device provided in this solution can solve the above problems.

[0062] 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.

[0063] The vehicle-mounted HUD sunlight focusing resistance testing device provided in this embodiment of the utility model, such as Figure 1 As shown, it includes:

[0064] Framework 3;

[0065] The first positioning device, which is set on the frame 3, is used to position and install the windshield 2.

[0066] Set on frame 3, for positioning the second positioning device for mounting HUD1;

[0067] The light source of the sunlight simulator can be focused on the test position of HUD1 through the windshield 2 and form a light spot; the first positioning device and / or the second positioning device can be adjusted relative to the frame 3 so that the installation position of the windshield 2 and / or HUD1 can be adjusted so that the light spot formed at the test position of HUD1 is consistent with the theoretical light spot.

[0068] It should be noted that HUD1 is a (vehicle-mounted) head-up display. The mounting points (such as mounting ears) of the head-up display are complete, the head-up display can be lit and worked normally, and it is positioned and installed through the first positioning device, which is the HUD positioning device.

[0069] Windshield 2 is a car windshield that is matched with HUD1. The windshield is designed with the minimum usable area based on the light incident position and the size of the light source. The windshield is cut to obtain the windshield 2. In other words, windshield 2 can be a windshield obtained by cutting a specific area of ​​the car windshield. This facilitates the quick installation and removal of windshield 2. Windshield 2 is positioned and installed by a second positioning device, which is a windshield positioning device.

[0070] Frame 3 serves as the base of the entire testing device;

[0071] The sunlight simulator is used to emit simulated sunlight and can be located at the front and top of frame 3. The windshield 2 is located between the sunlight simulator and HUD1. The light source of the sunlight simulator can be focused on the test position of HUD1 through the windshield 2 and form a light spot. In other words, the light source of the sunlight simulator can be focused on the test position of HUD1 through the windshield 2 and form a light spot.

[0072] In the first and second positioning devices, at least the first positioning device is movable relative to the frame 3 (and the second positioning device is also movable relative to the frame 3) so that the installation position of the windshield 2 can be adjusted, thereby ensuring that the light spot formed at the test position of the HUD1 is consistent with the theoretical light spot. This allows for precise matching of the positions of the windshield 2 and HUD1 based on the solar light source, enabling position calibration of the windshield 2 and HUD1. This facilitates the simulation of precise positions under actual vehicle conditions, accurately achieving the same sunlight focusing position as under actual vehicle conditions. The positioning device can be adjusted while calibrating the light spot, meaning the focused light spot is adjusted to match the theoretical state (such as size and shape). Furthermore, the vehicle-mounted HUD sunlight focusing resistance testing device provided in this solution can be used for thermal reliability testing of internal HUD components under sunlight focusing conditions. In addition, this vehicle-mounted HUD sunlight focusing resistance testing device also serves as a testing fixture for vehicle-mounted HUD sunlight focusing resistance.

[0073] In other words, the vehicle-mounted HUD sunlight focusing test device provided in this solution has an adjustable windshield positioning device and / or HUD positioning device, so that the relative position of the windshield and / or HUD relative to the solar simulator light source can be adjusted, so that the light spot formed at the test position of HUD1 is consistent with the theoretical light spot. In other words, the position of the windshield and HUD can be accurately matched according to the solar light source, so that the installation posture of the windshield and HUD can be accurately positioned.

[0074] In short, the vehicle-mounted HUD sunlight focusing resistance testing device provided in this solution has an adjustment function. It can accurately position the HUD and windshield relative to the sunlight simulator light source according to the incident angle of the maximum power light from the sunlight simulator, so as to obtain the same sunlight focusing spot as the theoretical state, realize the sunlight focusing resistance performance test of the vehicle-mounted HUD, and verify the product performance.

[0075] In this solution, the first positioning device is slidably adjustable relative to the frame 3 and can be locked to the frame 3;

[0076] The second positioning device is adjustable relative to the frame 3 and can be locked to the frame 3.

[0077] The first positioning device is slidably disposed on the frame 3 and can be locked to the frame 3 after sliding, thus achieving locking after adjustment; similarly, the second positioning device is slidably disposed on the frame 3 and can be locked to the frame 3 after sliding, thus achieving fixing after adjustment.

[0078] In other words, both the first positioning device and the second positioning device can be adjusted relative to the frame 3 so that the installation positions of the windshield 2 and HUD1 can be adjusted. This makes it easier to ensure that the light spot formed at the test position of HUD1 is consistent with the theoretical light spot. Of course, the first positioning device and the second positioning device can also be adjusted relative to the frame 3 in other ways, such as rotation adjustment in multiple directions, which will not be elaborated here.

[0079] Specifically, such as Figure 2 As shown, frame 3 includes a grid-shaped frame, and each side of it has a grid-shaped structure;

[0080] The first positioning device includes: a plurality of first positioning components;

[0081] like Figure 1 As shown, multiple first positioning components are slidably disposed on the grid-shaped frame and are used to install multiple edges of the windshield 2 one by one, and can all be locked to the grid-shaped frame.

[0082] The second positioning device includes: a plurality of second positioning components;

[0083] like Figure 1 As shown, multiple second positioning components are slidably disposed on the grid-shaped frame and are used to install multiple mounting ears of HUD1, and can all be locked to the grid-shaped frame.

[0084] It should be noted that, as Figure 2 As shown, frame 3 is a grid-shaped truss structure, resembling a grid from all sides, and composed of 13 profiles. This design ensures that sunlight is not blocked while maintaining structural stability, and also facilitates the assembly and disassembly of the platform for transport as a whole. The top of the grid-shaped frame is open, facilitating the placement and removal of HUD1 and windshield 2. The windshield 2 can be designed based on the light source's position and size to reduce the platform's volume and facilitate disassembly and reconfiguration. Of course, frame 3 can also employ other truss structures, such as a grid-shaped truss structure, which will not be elaborated upon here.

[0085] like Figure 1 As shown, multiple first positioning components are slidably mounted on multiple profiles (horizontal or vertical beams) of the grid-shaped frame, and are used to install multiple edges of the windshield 2, and can all be locked to their respective profiles, thus achieving sliding locking of the first positioning components; of course, as Figure 1As shown, the windshield 2 is tilted within the grid frame and faces the solar simulator. By sliding and adjusting multiple first positioning components, the windshield 2 can be flipped and adjusted within the grid frame. Details are described below.

[0086] like Figure 1 As shown, multiple second positioning components are slidably mounted on multiple profiles (horizontal or vertical beams) of the grid frame, and are used to install multiple mounting ears of the HUD1, all of which can be locked to their respective profiles, thus achieving sliding locking of the second positioning components; of course, as Figure 1 As shown, HUD1 is tilted within the grid-shaped frame and faces the windshield 2. Through the sliding adjustment of multiple second positioning components, the windshield 2 can be adjusted in the X and Y directions within the grid-shaped frame. Details are described below.

[0087] In other words, the frame 3 adopts a grid-type truss structure, which does not block sunlight and has high structural strength; in addition, the first positioning device uses multiple sliding first positioning components to install multiple edges of the windshield 2, which facilitates the adjustment of the installation position of the windshield 2; similarly, the second positioning device uses multiple sliding second positioning components to install multiple mounting ears of the HUD1, which also facilitates the adjustment of the installation position of the HUD1.

[0088] Furthermore, the plurality of first positioning components include: two first upper positioning components and two first lower positioning components;

[0089] like Figure 1 and Figure 2 As shown, the two first upper positioning components can slide along the length of the upper left crossbeam 31 and the upper right crossbeam 32 of the grid frame, respectively, and are used to install the left and right edges of the windshield 2, respectively.

[0090] like Figure 1 and Figure 2 As shown, the two first lower positioning components can slide along the length of the front left vertical beam 33 and the front right vertical beam 34 of the grid frame, respectively, and are used to install the lower left and lower right corners of the windshield 2, respectively.

[0091] It should be noted that, as Figure 2 As shown, the two first upper positioning components can be a first upper left positioning component and a first upper right positioning component; wherein, the first upper left positioning component is slidably disposed on the top of the upper left crossbeam 31 and can slide along the length direction of the upper left crossbeam 31, and is used to install the left edge of the windshield 2; the first upper right positioning component is slidably disposed on the top of the upper right crossbeam 32 and can slide along the length direction of the upper right crossbeam 32, and is used to install the right edge of the windshield 2; the first upper left positioning component and the first upper right positioning component are symmetrically distributed from left to right; as shown Figure 1 As shown, the first upper left positioning component and the first upper right positioning component are used to adjust the front and rear positions of the left and right edges of the windshield 2, respectively.

[0092] like Figure 2 As shown, the two first lower positioning components can be a first lower left positioning component and a first lower right positioning component; wherein, the first lower left positioning component is slidably disposed on the right side of the front left vertical beam 33, and can slide along the length direction of the front left vertical beam 33, and is used to install the left corner of the windshield 2; the first lower right positioning component is slidably disposed on the left side of the front right vertical beam 34, and can slide along the length direction of the front right vertical beam 34, and is used to install the right corner of the windshield 2; the first lower left positioning component and the first lower right positioning component are symmetrically distributed from left to right; as Figure 1 As shown, the first lower left positioning component and the first lower right positioning component are used to adjust the upper and lower positions of the left and right corners of the windshield 2, respectively. In this way, combined with the forward and backward sliding adjustment of the two first upper positioning components, the windshield 2 can be flipped and adjusted, thereby adjusting the orientation of the windshield 2 relative to the sunlight simulator.

[0093] Furthermore, such as Figure 2 As shown, the first upper positioning component includes: a first upper positioning block 41 and a first upper locking member;

[0094] The first upper positioning block 41 is slidably disposed on the upper left crossbeam 31 or the upper right crossbeam 32 for installing the left and right edges of the windshield 2; the first upper locking member is used to lock the first upper positioning block 41.

[0095] The first lower positioning component includes: a first lower positioning block 42 and a first lower locking member;

[0096] The first lower positioning block 42 can be slidably set on the front left vertical beam 33 or the front right vertical beam 34 for installing the lower left and lower right corners of the windshield 2; the first lower locking member is used to lock the first lower positioning block 42.

[0097] It should be noted that, as Figure 2 As shown, the first upper left positioning component described above includes: a first upper left positioning block and a first upper left locking member; the first upper left positioning block is slidably disposed on the top of the upper left crossbeam 31 and can slide along the length direction of the upper left crossbeam 31, and is used to install the left edge of the windshield 2; the first upper left locking member is used to lock the first upper left positioning block to the top of the upper left crossbeam 31.

[0098] The first upper right positioning component described above includes: a first upper right positioning block and a first upper right locking member; the first upper right positioning block is slidably disposed on the top of the upper right crossbeam 32 and can slide along the length direction of the upper right crossbeam 32, and is used to install the right edge of the windshield 2; the first upper right locking member is used to lock the first upper right positioning block to the top of the upper right crossbeam 32.

[0099] The first lower left positioning component described above includes: a first lower left positioning block and a first lower left locking member; the first lower left positioning block is slidably disposed on the right side of the front left vertical beam 33 and can slide along the length direction of the front left vertical beam 33, and is used to install the left corner of the windshield 2; the first lower left locking member is used to lock the first lower left positioning block to the right side of the front left vertical beam 33.

[0100] The first lower right positioning component described above includes: a first lower right positioning block and a first lower right locking member; the first lower right positioning block is slidably disposed on the left side of the front right vertical beam 34 and can slide along the length direction of the front right vertical beam 34, and is used to install the right corner of the windshield 2; the first lower right locking member is used to lock the first lower right positioning block to the left side of the front right vertical beam 34.

[0101] Among them, such as Figure 2 As shown, the sliding mechanism of the first upper left positioning block, the first upper right positioning block, the first lower left positioning block, and the first lower right positioning block with their corresponding profiles can adopt a groove + slider structure. For example, a groove is provided at the top of the upper left crossbeam 31 along its length, and a slider is provided at the bottom of the first upper left positioning block, located within the groove of the upper left crossbeam 31 and able to slide along the groove, thus realizing the sliding design of the first upper left positioning block along the upper left crossbeam 31. Of course, to prevent the first upper left positioning block from sliding off, its slider and corresponding groove can adopt a dovetail block + dovetail groove structure. In addition, the sliding design of other positioning blocks is similar. Furthermore, the first upper left locking component, the first upper right locking component, the first lower left locking component, and the first lower right locking component can all be locking bolt assemblies. The locking bolt assemblies lock the positioning blocks by locking the mounting through holes of the positioning blocks. Of course, the positioning blocks can be obtained by 3D printing.

[0102] In other words, both the first upper positioning component and the first lower positioning component adopt the structure of positioning block + locking element, which not only facilitates the installation of the corresponding parts of the windshield 2, but also facilitates the sliding adjustment and sliding locking of the corresponding parts of the windshield 2.

[0103] In this plan, such as Figure 9 As shown, the first upper positioning block 41 is provided with a conformal inclined surface 411, which is used to adapt to the back of the left or right edge of the windshield 2.

[0104] like Figure 10As shown, the first lower positioning block 42 has an inclined groove 421, which is used to insert into the lower left or lower right corner of the windshield 2.

[0105] It should be noted that, as Figure 9 The first upper positioning block 41 shown is the first upper right positioning block, and the conformal inclined surface 411 is provided to adapt to the back side of the right edge supporting the windshield 2 (e.g., Figure 6 As shown), the first upper left positioning block has a conforming inclined surface 411 for adapting to support the back of the left edge of the windshield 2; wherein, the shape of the conforming inclined surface 411 of the first upper right positioning block is adapted to the shape of the back of the right edge of the windshield 2, and the shape of the conforming inclined surface 411 of the first upper left positioning block is adapted to the shape of the back of the left edge of the windshield 2, which can respectively achieve close support for the back of the left and right edges of the windshield 2.

[0106] like Figure 10 The first lower positioning block 42 shown is the first lower right positioning block, and the groove 421 provided is for insertion into the lower right corner of the windshield 2 (e.g., Figure 7 As shown), the first lower left positioning block has a groove 421 for inserting the lower left corner of the windshield 2; of course, the lower right and lower left corners of the windshield 2 can also be removed from the corresponding groove 421, and the width of the groove 421 can be 10mm; this design allows for back support and bottom insertion of the windshield 2, which not only facilitates the installation and removal of the windshield 2, but also facilitates the flipping and adjustment of the windshield 2; in addition, as Figure 10 As shown, the groove wall of the groove 421 of the first lower positioning block 42 is also provided with a conformal surface 422, which is used to fit and conform to the back of the lower left or lower right corner of the windshield 2 for installation (support).

[0107] Specifically, such as Figure 2 As shown, a lower crossbeam 37 is provided between the front lower crossbeam 35 and the rear lower crossbeam 36 of the grid-shaped frame;

[0108] The multiple second positioning components include: a second upper positioning component, a second middle positioning component, and a second lower positioning component;

[0109] like Figure 3 As shown, the second upper positioning component can slide along the length of the rear upper crossbeam 38 of the grid frame and is used to install the upper mounting ear 11 of the HUD1.

[0110] like Figure 4 As shown, the second positioning component can slide along the length of the lower left crossbeam 39 of the grid frame and is used to install the middle mounting ear 12 of the HUD1.

[0111] like Figure 5As shown, the second lower positioning component can slide along the length of the lower crossbeam 37 and is used to mount the lower mounting ear 13 of the HUD1.

[0112] It should be noted that the lower crossbeam 37 is also a profile and is connected between the front lower crossbeam 35 and the rear lower crossbeam 36 of the grid frame;

[0113] like Figure 3 As shown, the second upper positioning component is slidably disposed on the top of the rear upper crossbeam 38 and can slide along the length direction of the rear upper crossbeam 38, and is used to install the upper mounting ear 11 of the HUD1, thereby adjusting the left and right positions of the upper mounting ear 11 of the HUD1.

[0114] like Figure 4 As shown, the second positioning component is slidably disposed on the top of the lower left crossbeam 39 and can slide along the length direction of the lower left crossbeam 39, and is used to install the middle mounting ear 12 of HUD1, and then to adjust the front and rear position of the middle mounting ear 12 of HUD1.

[0115] like Figure 5 As shown, the second lower positioning component is slidably disposed on the side of the lower crossbeam 37 and can slide along the length direction of the lower crossbeam 37. It is used to install the lower mounting ear 13 of the HUD1 and to adjust the front and rear position of the lower mounting ear 13 of the HUD1. Of course, the adjustment of the corresponding mounting ear of the HUD1 by the above positioning components is a fine adjustment, and the second upper positioning component, the second middle positioning component and the second lower positioning component can all be locked on the crossbeam.

[0116] In other words, there are three second positioning components, and each is used to install one of the three mounting ears of HUD1. This not only makes it easier for HUD1 to be stably installed in the frame 3, but also makes it easier to make targeted sliding adjustments to HUD1.

[0117] Furthermore, such as Figure 3 As shown, the second upper positioning assembly includes: a second upper positioning block 51 and a second upper locking member; wherein, the structure of the second upper positioning block 51 can be referred to Figure 8 As shown;

[0118] The second upper positioning block 51 is slidably disposed on the rear upper crossbeam 38 for mounting the upper mounting ear 11; the second upper locking member is used to lock the second upper positioning block 51.

[0119] like Figure 4 As shown, the second positioning component includes: a second positioning block 52 and a second locking member;

[0120] The second positioning block 52 is slidably disposed on the lower left crossbeam 39 and is used to install the mounting ear 12; the second locking component is used to lock the second positioning block 52.

[0121] like Figure 5 As shown, the second lower positioning component includes: a second lower positioning block 53 and a second lower locking member;

[0122] The second lower positioning block 53 is slidably disposed on the lower crossbeam 37 and is used to install the lower mounting ear 13; the second lower locking member is used to lock the second lower positioning block 53.

[0123] It should be noted that, as Figure 3 As shown, the second upper positioning block 51 is slidably disposed on the top of the rear upper crossbeam 38 and can slide along the length direction of the rear upper crossbeam 38, and is used to install the upper mounting ear 11, thereby adjusting the left and right positions of the upper mounting ear 11; the second upper locking member is used to lock the second upper positioning block 51 to the top of the rear upper crossbeam 38, thereby realizing the sliding locking of the second upper positioning block 51.

[0124] like Figure 4 As shown, the second positioning block 52 is slidably disposed on the top of the lower left crossbeam 39 and can slide along the length of the lower left crossbeam 39, and is used to install the mounting ear 12, thereby adjusting the front and rear position of the mounting ear 12; the second locking member is used to lock the second positioning block 52 to the top of the lower left crossbeam 39.

[0125] like Figure 5 As shown, the second lower positioning block 53 is slidably disposed on the left side of the lower crossbeam 37 and can slide along the length of the lower crossbeam 37, and is used to install the lower mounting ear 13, thereby adjusting the front and rear position of the lower mounting ear 13; the second lower locking member is used to lock the second lower positioning block 53 to the left side of the lower crossbeam 37.

[0126] Among them, such as Figure 2 As shown, the sliding method of the second upper positioning block 51, the second middle positioning block 52, and the second lower positioning block 53 with the corresponding crossbeam can adopt a slide groove + slider structure. For details, please refer to the sliding method of the first upper left positioning block mentioned above, which will not be repeated here. In addition, the second upper locking member, the second middle locking member, and the second lower locking member can also adopt a locking bolt assembly. The locking bolt assembly locks the positioning blocks by locking the mounting through holes on the positioning blocks. Of course, the positioning blocks can be obtained by 3D printing.

[0127] In other words, the second upper positioning component, the second middle positioning component, and the second lower positioning component all adopt the structure of positioning block + locking element, which not only facilitates the installation of the corresponding mounting ears of HUD1, but also facilitates the sliding adjustment of the corresponding mounting ears of HUD1.

[0128] Furthermore, such as Figure 8 As shown, the second upper positioning block 51 is provided with a first inclined surface 511 for adapting to the installation of the upper mounting ear 11, and is provided with a first positioning structure for cooperating with the upper mounting ear 11.

[0129] like Figure 4 As shown, the second positioning block 52 is provided with a second inclined surface 521 for adapting to the mounting ear 12, and is provided with a second positioning structure for cooperating with the mounting ear 12.

[0130] like Figure 5 As shown, the second lower positioning block 53 is provided with a third inclined surface 531 for adapting to the installation of the lower mounting ear 13, and is provided with a third positioning structure for cooperating with the lower mounting ear 13.

[0131] Among them, such as Figure 2 As shown, the first inclined plane 511, the second inclined plane 521 and the third inclined plane 531 are parallel.

[0132] It should be noted that, as Figure 3 As shown, the second upper positioning block 51 has a first inclined surface 511 for adapting to the mounting surface of the upper mounting ear 11. The shape of the first inclined surface 511 is adapted to the shape of the mounting surface of the upper mounting ear 11. The first inclined surface 511 also has a first positioning structure for cooperating with the pin hole structure of the mounting surface of the upper mounting ear 11 to support and position the upper mounting ear 11. The pin hole structure of the mounting surface of the upper mounting ear 11 includes an upper positioning pin and an upper positioning hole. Figure 8 As shown, the first positioning structure includes: a first positioning pin 512 and a first positioning hole 513; the first positioning pin 512 is used to cooperate with the upper positioning hole of the upper mounting ear 11, and the first positioning hole 513 is used to cooperate with the upper positioning pin of the upper mounting ear 11.

[0133] like Figure 4 As shown, the second positioning block 52 has a second inclined surface 521, which is used to adapt to the mounting surface of the middle mounting ear 12. The shape of the second inclined surface 521 is adapted to the shape of the mounting surface of the middle mounting ear 12. The second inclined surface 521 also has a second positioning structure for cooperating with the pin structure of the mounting surface of the upper mounting ear 11, so as to support and position the middle mounting ear 12. The pin structure of the mounting surface of the middle mounting ear 12 includes a middle positioning pin. The second positioning structure includes a second positioning hole. The second positioning hole is used to cooperate with the middle positioning pin of the middle mounting ear 12.

[0134] like Figure 5As shown, the second lower positioning block 53 has a third inclined surface 531, which is used to adapt to the mounting surface of the lower mounting ear 13. The shape of the third inclined surface 531 is adapted to the shape of the mounting surface of the lower mounting ear 13. The third inclined surface 531 also has a third positioning structure for cooperating with the pin hole structure of the mounting surface of the lower mounting ear 13 to support and position the lower mounting ear 13. The pin hole structure of the mounting surface of the lower mounting ear 13 includes a lower positioning pin and a lower positioning hole. The third positioning structure includes a third positioning pin and a third positioning hole. The third positioning pin is used to cooperate with the lower positioning hole of the lower mounting ear 13, and the third positioning hole is used to cooperate with the lower positioning pin of the lower mounting ear 13.

[0135] At the same time, such as Figure 2 As shown, the first inclined plane 511 (as Figure 3 As shown), the second inclined plane 521 (as shown) Figure 4 (as shown) and the third inclined plane 531 (as shown) Figure 5 (As shown) are parallel to each other, ensuring support for the corresponding mounting surfaces of the mounting ears. Furthermore, based on the pin-hole positioning structure, the HUD1 can be supported and positioned for its corresponding mounting ears without the need for bolt assemblies, facilitating the assembly and disassembly of the HUD1 and improving testing efficiency. Of course, both the HUD1 and the windshield 2 are flexible, and the sliding adjustments of both are micro-adjustments. Even during sliding adjustments, compression or stretching may occur, but these deformations are within the acceptable range.

[0136] like Figure 1 As shown, the vehicle-mounted HUD sunlight focusing resistance testing device provided in this embodiment of the present invention also includes a base 6;

[0137] The base 6 can rotate around the vertical direction;

[0138] Frame 3 is mounted on base 6.

[0139] The base 6 can be a turntable that rotates around the Z-axis, and the frame 3 can be mounted on this turntable to adjust the orientation of the frame 3. This allows the windshield 2 and HUD 1, which are mounted on it, to better face the sunlight simulator; where, for example Figure 11 As shown, the base 6 has four fourth mounting through holes 61 for mounting the frame 3.

[0140] In addition, this solution also provides a procedure for precise adjustment and calibration of this testing device (procedure for precise positioning adjustment):

[0141] Step 1: Rough positioning and installation of HUD and windshield; Assemble the vehicle-mounted HUD sunlight focusing resistance test device, and assemble the HUD and windshield onto the corresponding positioning device to complete the rough positioning of HUD and windshield.

[0142] Step 2: Fitting the surface shape of the windshield's light-transmitting area; Based on the point cloud model of the windshield's light-transmitting area obtained by the measuring equipment, the point cloud of the windshield's light-transmitting area is spatially fitted using the three-point initial alignment and reference point system alignment method; The measuring equipment can be a coordinate measuring machine, a robotic arm-type coordinate measuring machine, or a handheld 3D measuring instrument.

[0143] Step 3: Fine positioning and adjustment of HUD and windshield; Based on the point cloud model of the positioning device of the test device obtained by the measuring equipment, and based on the fitting results of the light-transmitting area, the actual value from the light-transmitting area of ​​the windshield to the HUD installation point is obtained. If the theoretical position deviation requirement is not met, the position of the first positioning device in the grid frame is finely adjusted, that is, by finely adjusting the position of the first upper positioning block and / or the first lower positioning block. Of course, the size scale on the corresponding profile can be referred to when sliding adjustment.

[0144] Step 4: Confirm the size of the light spot to be tested; measure the size and shape of the light spot at the HUD test position, and confirm that it is consistent with the theoretical state of the light spot. After confirmation, the calibration of the test device is completed.

[0145] In addition, this HUD sunlight-focusing resistance testing device can perform thermal reliability testing on diffusion films / TFT modules under sunlight focusing environment, and this testing device also has the following features:

[0146] The testing device has high precision, good position matching, accurate sunlight focusing position, and accurate test results.

[0147] The positioning references the conformal design of the windshield and HUD, resulting in high precision, good position matching, and adjustable device.

[0148] The testing equipment is highly reusable; only the positioning device needs to be replaced after each product update.

[0149] The truss structure has high structural strength, facilitates the assembly and disassembly of the platform, and can be transported as a whole.

[0150] The test device incorporates a windshield designed based on the light incident position and light source size, reducing the size of the test stand and facilitating disassembly and replacement.
