[0054] The head-up display test bench provided in the embodiment of the utility model can be used for testing the imaging quality of the HUD, such as the luminance chroma test, the eyebox test, the virtual image distance test and the like.

[0055] The head-up display device 23 is a HUD device.

[0056] The head-up display device 23 is a HUD device.

[0057] The head-up display device 23 is a HUD device.

[0058] In the embodiment, any one of the head-up display device 23, the windshield component 6 and the collection device 43 can be a real automobile component, so as to further improve the detection accuracy. The windshield component 6 is preferably a front windshield. The collection device 43 can be a camera, so as to collect corresponding image information; or the collection device 43 is an imaging brightness chroma meter, so as to collect corresponding brightness information. The collection device 43 can also be other equipment, and the specific type is determined according to the test requirement. The types of the head-up display device 23 are different, which can be different models. Similarly, the types of the windshield component 6 are different, which can be different models.

[0059] The head-up display test bench provided in the embodiment of the utility model can be used for testing the imaging quality of the HUD, such as the luminance chroma test, the eyebox test, the virtual image distance test and the like.

[0060] In order to improve the clamping stability of the clamping combination structure on the windshield component 6, the clamping combination structure comprises a windshield component fixing frame 32 and a windshield component clamping piece 33. The hollow area of the windshield component fixing frame 32 can accommodate the windshield component 6; the windshield component clamping piece 33 is connected with the windshield component fixing frame 32 and can clamp the edge of the windshield component 6. Among them, the number of windshield component clamping pieces 33 can be multiple and arranged along the circumference of the windshield component fixing frame 32. Among them, different windshield component clamping pieces 33 can clamp different positions of the edge of the windshield component 6.

[0061] Further, the number of windshield component clamping pieces 33 can be even, and two by two symmetrically arranged at the edge of the windshield component 6. That is, the windshield component clamping piece 33 is two by two, installed on the windshield component fixing frame 32, for symmetrically clamping the windshield component 6.

[0062] The clamping combination structure can also be other structures, such as only having a windshield component clamping piece 33, or a combination of a windshield component fixing frame 32 and a connecting bolt, so that the windshield component 6 can be positioned by the connecting bolt and the windshield component fixing frame 32.

[0063] In different clamping combination structures, the windshield component fixing frame 32 is different; and / or in different clamping combination structures, the windshield component clamping piece 33 is different. That is, when testing the head-up display device 23 and the windshield component 6 of different vehicle models, different windshield component fixing frames 32 can be selected to match the windshield component 6. Different windshield component clamping pieces 33 can also be selected to match the windshield component 6. Different windshield component fixing frames 32 and windshield component clamping pieces 33 can also be selected to match the windshield component 6.

[0064] That is, according to the test of different types of windshield components 6 of different vehicle models, different types of windshield component fixing frames 32 are replaced. Or, different types of windshield component clamping pieces 33 are replaced. Or, by replacing the clamping combination structure, the clamping mode of the different windshield components 6 is realized. Among them, the clamping mode of the clamping combination structure on the windshield component 6 is that the windshield component clamping piece 33 clamps the edge of the windshield component 6 and the windshield component fixing frame 32 stabilizes the windshield component clamping piece 33; or a clamping piece that can directly clamp the middle area of the windshield component 6 can be used to position the windshield component 6.

[0065] Among them, the windshield component clamping piece 33 can be a conformal support clamp block, and the specific clamping position (such as the clamping surface) depends on the structure stability of the windshield component 6.

[0066] In order to facilitate position adjustment and positioning, the number of second adjustment and positioning devices 31 is multiple, and different second adjustment and positioning devices 31 can be used to match different types of clamping combination structures.

[0067] A general second adjusting and positioning device 31, such as a six-axis robot (six-axis mechanical arm), can also be selected to adjust the position of the clamping combined structure.

[0068] In the embodiment of the utility model, in order to improve the positioning stability of the wind shielding component 6, the second adjusting and positioning device 31 comprises a detachable bottom plate 312, a combined structure positioning piece 314 and a combined structure support seat 313. The detachable bottom plate 312 is detachably connected with the second base 12. The combined structure positioning piece 314 can be detachably connected with the clamping combined structure. One end of the combined structure support seat 313 can be connected with the detachable bottom plate 312, and the other end of the combined structure support seat 313 is connected with the combined structure positioning piece 314. The number of the combined structure support seats 313 is multiple, and the lengths of the combined structure support seats 313 are different. The length of the combined structure support seat 313 is the size from one end to the other end.

[0069] The combined structure support seats 313 with different lengths are of different types. The combined structure support seats 313 of different types can be adaptively adjusted in structure in addition to the difference in length.

[0070] By replacing the combined structure support seats 313 with different sizes, the overall structure of the second adjusting and positioning device 31 (including the relative position of the detachable bottom plate 312 and the combined structure positioning piece 314) can be adjusted, and thus the position of the clamping combined structure can be adjusted.

[0071] The second adjusting and positioning device 31 formed after replacing the combined structure support seats 313 with different sizes is different second adjusting and positioning device 31. Other structures (such as the detachable bottom plate 312 and the combined structure positioning piece 314) of the second adjusting and positioning device 31 can also be set to different structures. Different second adjusting and positioning devices 31 are selected according to actual needs, and the detachable connection between the detachable bottom plate 312 and the second base 12 realizes the replacement of different second adjusting and positioning devices 31.

[0072] In the embodiment, the detachable bottom plate 312 and the fixing seat 121 of the second base 12 are positioned and fixed by positioning pins and bolts. Of course, buckles and other components can also be used for connection and fixation. In the embodiment, the type of the wind shielding component mechanism can be replaced according to different test requirements. The gantry body 1 can be repeatedly used in the test of different vehicle models and the test of different test requirements, which reduces the processing cost of the test bench and the design time in the early stage, and thus improves the test efficiency.

[0073] Specifically, the combined structure positioning member 314 can be connected with the wind deflector fixed frame 32 of the combined structure. In an embodiment, the wind deflector fixed frame 32 is provided with a positioning pin, and the positioning pin cooperates with a positioning groove of the combined structure positioning member 314 to ensure the positioning accuracy of the wind deflector fixed frame 32 relative to the combined structure positioning member 314, and to ensure the repeated positioning accuracy during the replacement of the wind deflector fixed frame 32.

[0074] Due to the factors such as the machining and assembly errors of the test bench and the machining errors of the wind deflector 6, there is a problem of low test accuracy of the test bench. In order to improve the test accuracy, the second adjusting and positioning device 31 further comprises an adjusting block assembly 311; the adjusting block assembly 311 comprises a first adjusting block 3111 and a second adjusting block 3112, the first adjusting block 3111 is connected with the detachable bottom plate 312, one end of the combined structure support seat 313 is connected with the second adjusting block 3112, and the first adjusting block 3111 and the second adjusting block 3112 can adjust the spacing through adjusting shims. Among them, by setting adjusting shims with different thicknesses between the first adjusting block 3111 and the second adjusting block 3112, the spacing of the first adjusting block 3111 and the second adjusting block 3112 can be different, thereby realizing the fine adjustment of the position of the combined structure support seat 313 relative to the detachable bottom plate 312. That is, the installation position of the wind deflector 6 can be fine adjusted through the adjusting block assembly 311, and the problem of low test accuracy caused by the machining and assembly errors of the test bench and the machining errors of the wind deflector 6 and the like can be effectively solved.

[0075] The adjusting shims are preferably U-shaped adjusting shims.

[0076] The combined structure support seat 313 and the combined structure positioning member 314 can be fixedly connected through bolts or bayonets, and are installed on the second adjusting block 3112 for supporting and positioning the wind deflector fixed frame 32.

[0077] In the embodiment, the second adjusting block 3112 can be movably connected with the detachable bottom plate 312, the first adjusting block 3111 is fixedly connected with the detachable bottom plate 312, and the fine adjustment can be realized along the extension direction (horizontal direction) of the detachable bottom plate 312 through the adjustment of the adjusting shims. Alternatively, the second adjusting block 3112 can be movably connected with the first adjusting block 3111, and the second adjusting block 3112 is located on the side of the first adjusting block 3111 away from the detachable bottom plate 312, and the fine adjustment can be realized along the direction close to and away from the detachable bottom plate 312 (vertical direction) through the adjustment of the adjusting shims.

[0078] In the embodiment, the first adjusting block 3111 is fixedly connected with the detachable bottom plate 312 through bolts or the like, and the second adjusting block 3112 is movably arranged on the detachable bottom plate 312.

[0079] Further, the second adjusting positioning device 31 further comprises a support table 315, the support table 315 has opposite first and second surfaces, the first surface is connected with the detachable bottom plate 312, and the second surface is connected with one end of the combined structure support seat 313. The support table 315 can be a frame structure connected by a plurality of sheet metal parts. By arranging the support table 315, the combined structure support seat 313 can be adjusted in the height direction, so that the total length of the support table 315 and the combined structure support seat 313 meets the adjustment requirement.

[0080] Of course, the support table 315 can also not be arranged, so that the length of the combined structure support seat 313 meets the adjustment requirement.

[0081] In order to facilitate adjustment, the first adjusting positioning device 21 comprises a first six-axis robot and a head-up display bracket 22 arranged at the driving end of the first six-axis robot, and the head-up display device 23 is arranged on the head-up display bracket 22. The first six-axis robot can adjust the position of the driving end according to the actual control of the operator, and then adjust the head-up display device 23 through the connection of the head-up display bracket 22.

[0082] In the embodiment, the head-up display bracket 22 has three legs corresponding to the three support ears of the head-up display device 23. In use, the positioning pins of the support ears of the head-up display device 23 are inserted into the pin holes of the legs of the head-up display bracket 22, and are fixed by bolts. The head-up display bracket 22 is fixedly connected with the driving end (the end of the sixth axis) of the first six-axis robot through a flange plate, and the head-up display device 23 can be moved to a position corresponding to the actual vehicle by controlling the six-axis rotation of the first six-axis robot.

[0083] Similarly, the third adjusting positioning device 41 comprises a second six-axis robot and a collection bracket 42 arranged at the driving end of the second six-axis robot, and the collection device 43 is arranged on the collection bracket 42. The second six-axis robot can adjust the position of the driving end according to the actual control of the operator, and then adjust the collection device 43 through the connection of the collection bracket 42.

[0084] The collection device 43 in the embodiment is a camera, which is positioned by a positioning pin and fixed by a bolt with the collection bracket 42 (camera support bottom plate), and the collection bracket 42 is installed on the driving end of the second six-axis robot through a flange plate. The collection device 43 (camera) can be adjusted to the eyebox position by controlling the six-axis rotation of the second six-axis robot, and has high repeatability.

[0085] That is, by adjusting the posture of the six-axis robot of the first adjusting positioning device 21 and the third adjusting positioning device 41, different types of head-up display devices 23 can be tested according to different vehicle models.

[0086] Of course, a four-axis robot or multiple linear driving devices (such as a three-dimensional driving device composed of an X-axis driving device, a Z-axis driving device, and a Y-axis driving device) can also be used, and no specific limitation is made herein and all are within the protection scope.

[0087] The head-up display test bench provided in the embodiment of the utility model further comprises a calibration assembly 5, the calibration assembly 5 comprises a calibration plate 51, and the acquisition device 43 can adjust the position and / or parameters through the calibration plate 51. That is, the calibration plate 51 of the calibration assembly 5 serves as a reference object, and the position and parameters of the acquisition device 43 are adjusted conveniently.

[0088] Further, the calibration assembly 5 further comprises a calibration plate support seat 52 and a calibration plate base 53. One end of the calibration plate support seat 52 is connected with the calibration plate 51; the calibration plate base 53 can be detachably connected with the first adjustment positioning device 21, and the other end of the calibration plate support seat 52 is connected with the calibration plate base 53. That is, the calibration plate 51 of the calibration assembly 5 shares the same first adjustment positioning device 21 with the head-up display device 23, after the position and parameters of the acquisition device 43 are adjusted, the calibration assembly 5 is detached from the first adjustment positioning device 21 and installed on the head-up display device 23. Through the above setting, the structure of the test bench is further simplified on the basis of meeting the test requirements, and the complexity and processing cost of the test bench are reduced. Of course, the adjustment positioning device can also be separately arranged and connected with the calibration assembly 5.

[0089] Specifically, the first adjustment positioning device 21 is a six-axis robot, wherein the calibration plate base 53 is installed at the driving end (the end of the six axes) of the six-axis robot. The calibration plate 51 is preferably a square calibration plate, which is installed above the calibration plate base 53 through the calibration plate support seat 52. After the acquisition mechanism 4 adjusts the acquisition device 43 to the eyebox position, the first adjustment positioning device 21 is controlled to adjust the calibration assembly 5 to the HUD imaging position and then fix it, and the parameters of the acquisition device 43 (the camera) are adjusted by using the calibration plate 51.

[0090] In order to facilitate carrying and position adjustment, any two adjacent bases among the first base 11, the second base 12, and the third base 13 are detachably connected; and the bottom of each of the first base 11, the second base 12, and the third base 13 is provided with a castor.

[0091] Since the test bench body 1 is large as a whole, the test bench body 1 is divided into three parts (a first base 11, a second base 12 and a third base 13), and a foot cup and a caster are installed below each part to facilitate the carrying and fixing of the test bench. When the test bench needs to be moved, the bolt of the foot cup is rotated upward to make the caster contact the ground; after the first base 11, the second base 12 and the third base 13 are moved to appropriate positions, the bolt of the foot cup is rotated downward to make the foot cup contact the ground, the base part is fixed, and then the first base 11, the second base 12 and the third base 13 are connected relative to each other.

[0092] The first base 11, the second base 12 and the third base 13 are connected and fixed by bolts or buckles and the like.

[0093] Specifically, the first base 11 and the third base 13 are installed on both sides of the second base 12, the first base 11 and the third base 13 are used to support the six-axis robot, and the second base 12 is used to support the wind blocking part 6.

[0094] During installation, the positioning pins on the first base 11 and the third base 13 are inserted into the bushings of the second base 12, and then the adjacent two bases are fixed by connecting plates and bolts on both sides and in the center.
