[0002] The Head-Up Display (HUD) system is an important product in the vehicle production and research and development process. It can project important information required for driving, such as vehicle speed, fuel level, navigation, and driving safety assistance, into the human eye. The projected image is located at a suitable position in front of the driver, so that the driver can always keep his head up, reducing the need for the driver to look down at the dashboard and navigation equipment, allowing them to keep their eyes on the road, improving reaction speed and driving concentration, and greatly improving driving safety.

[0042] The present invention provides a PGU module test bench 100 .

[0043] See also Figure 1 An embodiment of the PGU module test bench 100 includes a PGU module mounting mechanism 20, a slide mounting mechanism 30 and a tester mounting mechanism 40. The PGU module mounting mechanism 20 is provided with a mounting position for mounting a PGU module 50. The slide mounting mechanism 30 is spaced apart from the PGU module mounting mechanism 20. The slide mounting mechanism 30 is used to mount a slide, which is used to display an image generated by the PGU module 50 or light emitted through the PGU module 50. The tester mounting mechanism 40 is disposed on a side of the slide mounting mechanism 30 that is away from the PGU module mounting mechanism 20. The tester mounting mechanism 40 is used to mount a tester 43, which is used to obtain an image displayed by the slide or light emitted through the slide.

[0044] At present, the inspection of the PGU module 50 is mostly performed after the PGU module 50 is packaged into the HUD and then tested. If an unqualified PGU module 50 is detected or the PGU module 50 needs to be replaced for inspection, the HUD needs to be disassembled and assembled, and the operation process is relatively cumbersome. In order to avoid repeated disassembly and assembly of the HUD, the PGU module test bench 100 is provided with an installation position for installing the PGU module 50 on the PGU module installation mechanism 20. During testing, the PGU module 50 can be directly installed on the installation position for testing, thereby avoiding the complicated operation of repeated disassembly and assembly of the HUD. In order to realize the test of the PGU module 50, the PGU module test bench 100 also includes a slide mounting mechanism 30 and a tester mounting mechanism 40. The slide mounting mechanism 30 is spaced apart from the PGU module mounting mechanism 20. The slide mounting mechanism 30 is used to mount a slide, and the mounted slide is used to display the image generated by the PGU module 50 or the light emitted through the PGU module 50. The tester mounting mechanism 40 is arranged on the side of the slide mounting mechanism 30 away from the PGU module mounting mechanism 20. The tester mounting mechanism 40 is used to mount a tester 43, and the installed tester 43 is used to display the image displayed by the slide or the light emitted, so as to perform performance testing on the PGU module 50.

[0045] Reference Figure 1 and Figure 4 The projection film installation mechanism 30 includes a frame 32, and the frame 32 encloses an imaging port 321. The imaging port 321 is used to cover the projection film. The projection film can be but is not limited to an imaging film 34 and a light-transmitting plate 35. The imaging film 34 can be a diffusion film, a projection screen, a light-blocking glass, and other materials that can display a projected image, and is used to display the image generated by the PGU module 50. The material of the light-transmitting plate 35 is a light-shielding material, and a plurality of light-transmitting holes are opened on the light-transmitting plate 35 to allow the light emitted by the PGU module 50 to pass through.

[0046] Reference Figure 1 and Figure 6 The tester installation mechanism 40 includes a third support structure and a carrier plate 42. The carrier plate 42 is configured to be able to move vertically and horizontally on the third support structure. The carrier plate 42 is used to install a tester 43, and the tester 43 and the carrier plate 42 are detachably connected.

[0047] When the imaging port 321 is covered with an imaging film 34, the imaging film 34 can display the image generated by the PGU module 50. At this time, the tester 43 installed on the tester mounting mechanism 40 is a camera, which is used to capture the projected image projected on the imaging film 34. The camera can be connected to the mobile terminal for communication, or the SD card of the camera can be inserted into the card reader of the mobile terminal, so that the image captured by the camera can be uploaded to the mobile terminal, and the color temperature, color gamut, saturation, dark edges and corners of the projected image and whether distortion occurs can be analyzed through the mobile terminal, and the actual data obtained by the analysis can be compared with the theoretical data, so that the test personnel can obtain the real-time imaging data of the PGU module 50 in a timely manner.

[0048] When the imaging port 321 is covered with a light-transmitting plate 35, part of the light emitted by the PGU module 50 can be emitted from the light-transmitting hole. At this time, the tester 43 installed on the tester mounting mechanism 40 is an illuminance meter or an integrating sphere. The illuminance meter and the integrating sphere are used to obtain the luminous flux, color temperature, and illuminance of each light-transmitting hole, so as to judge the brightness uniformity of the image projected by the PGU module 50.

[0049] In summary, the PGU module test bench 100 can adapt to different types of testers 43 for detecting different performances of the PGU module 50, and each tester 43 is detachably connected to the carrier 42, such as a screw connection, a snap connection or a magnetic connection, etc. Therefore, during the detection process, it is only necessary to switch the imaging film 34 or the light-transmitting plate 35 in the slide mounting mechanism 30 and the tester 43 in the tester mounting mechanism 40 to complete the test of different performances of a single PGU module 50, and there is no need to move the PGU module 50 between different test benches, so that multiple performance tests of the PGU module 50 can be completed on one test line, which can reduce the number of test benches and reduce the detection cost.

[0050] In order to facilitate the rapid replacement of the slide, a first magnetic adsorption member 322 is provided on the frame 32, and a second magnetic adsorption member 351 is provided on the slide, and the slide is magnetically fixed to the frame 32 through the second magnetic adsorption member 351. The first magnetic adsorption members 322 are evenly arranged at the four corners of the frame 32, and the number and position of the second magnetic adsorption members 351 match the number and position of the first magnetic adsorption members 322. The first magnetic adsorption member 322 and the second magnetic adsorption member 351 can be magnets that attract each other, or one of the first magnetic adsorption member 322 and the second magnetic adsorption member 351 is a magnet, and the other is made of ferromagnetic material such as iron, cobalt, nickel, etc.

[0051] Reference Figure 2 and Figure 3In one embodiment of the present invention, the PGU module installation mechanism 20 includes a first supporting structure 21 and a fixed structure 22. The first supporting structure 21 has a liftable lifting platform 211. The fixed structure 22 is arranged on the lifting platform 211. The installation position is arranged on the fixed structure 22.

[0052] In this embodiment, the fixing mechanism is arranged on a liftable lifting platform 211, and the mounting position is arranged on the fixed structure 22, thereby allowing the test personnel to adjust the height of the PGU module 50 as needed to adapt to different optical path designs and test requirements, ensuring that different PGU modules 50 can accurately project the generated image or light onto the slide mounting mechanism 30 after adjustment, thereby further improving the flexibility of the test bench.

[0053] Among them, the PGU module 50 includes an electrically connected PGU body 51 and a first control board 52, and the mounting position includes a first mounting position and a second mounting position, the first mounting position and the second mounting position are arranged at intervals on the fixed structure 22, the first mounting position is used to install the PGU body 51, and the second mounting position is used to install the first control board 52.

[0054] The PGU body 51 is used to project images, and the first control board 52 is a DLP (Digital Light Processing) control board. The first control board 52 is electrically connected to the PGU body 51 and is used to control the PGU body 51 to generate projected images, etc. It should be noted that different PGU modules 50 may have the same PGU body 51, but different designs of the first control board 52; or different PGU bodies 51, but use the same first control board 52; or the PGU body 51 and the first control board 52 are different. In order to facilitate the separate replacement of the PGU body 51 and the first control board 52, in this embodiment, a first mounting position and a second mounting position are provided at intervals on the fixed structure 22. During testing, the PGU body 51 is detachably arranged on the first mounting position, and the first control board 52 is detachably arranged on the second mounting position, so that the tester can quickly replace the PGU body 51 and / or the first control board 52 according to needs.

[0055] In the embodiment shown in the figure, the fixed structure 22 includes a first platform 221 and a second platform 222. The first platform 221 is arranged on the table surface of the lifting platform 211, and the second platform 222 is arranged above the first platform 221 and spaced apart from the first platform 221. A first mounting position is formed between the first platform 221 and the second platform 222, and the table surface of the second platform 222 forms a second mounting position. At this time, the PGU body 51 is detachably arranged between the first platform 221 and the second platform 222, and the first control panel 52 is detachably arranged on the table surface of the second platform 222. This embodiment effectively utilizes the vertical space by arranging the first platform 221 and the second platform 222, and arranging the first platform 221 and the second platform 222 in layers, so that the structure of the PGU module mounting mechanism 20 is relatively compact.

[0056] A support seat 2211 is disposed on the first carrier 221 . The support seat 2211 is disposed on two opposite side edges of the first carrier 221 . The second carrier 222 is disposed on the top surface of the support seat 2211 and is detachably connected to the support seat 2211 .

[0057] In the embodiment shown in the figure, one end of the second carrier 222 is screwed to the support seat 2211 on the first side, and the other end of the second carrier 222 is snap-connected to the support seat 2211 on the second side. Specifically, a snap-fitting member 2212 is provided on the support seat 2211 on the second side, and the snap-fitting member 2212 is rotationally connected to the support seat 2211 through a rotating shaft and a torsion spring. The snap-fitting member 2212 is tightly snap-fitted with the edge of the second carrier 222 under the action of the torsion spring, thereby fixing the second carrier 222. At the same time, an unlocking portion is convexly provided on the outer side of the snap-fitting member 2212, and then the snap-fitting member 2212 can be released from the second carrier 222 by pressing the unlocking portion, so that the second carrier 222 can be easily removed. Of course, in actual application, both ends of the second carrier 222 can be connected to the corresponding support seat 2211 by screws or snap-on connections, without limitation here, so as to facilitate the removal of the second carrier 222 and the first control board 52 thereon, and facilitate the replacement of the PGU body 51.

[0058] The PGU module 50 also includes a second control board 53, which is a main control circuit board for controlling the PGU body 51 to switch pictures, adjust brightness, and connect to a remote control, etc. In order to facilitate the installation of the second control board 53, in some embodiments of the present invention, the fixed structure 22 also includes a vertical plate 223, which is arranged on the peripheral side of the first carrier 221 and the second carrier 222, and is used to install the second control board 53. During testing, the second control board 53 is detachably mounted on one side of the vertical plate 223, and the PGU body 51 and the first control board 52 are both electrically connected to the second control board 53. The setting of the vertical plate 223 provides a fixed mounting position for the second control board 53, thereby facilitating the wiring of the PGU body 51 and the first control board 52 with the second control board 53, saving the length of the wiring harness.

[0059] Reference Figure 4 and Figure 5 The slide installation mechanism 30 further includes a second supporting structure 31 , and a frame 32 is liftably disposed on the second supporting structure 31 .

[0060] Specifically, the second support structure 31 includes a chassis 311 and a vertical pole 312 disposed on the chassis 311. The frame 32 is provided with a through channel disposed opposite to the vertical pole 312. The vertical pole 312 is inserted into the through channel so that the frame 32 can slide up and down along the vertical pole 312. The liftable design of the frame 32 allows the tester to adjust the height of the frame 32 to meet the projection requirements of the PGU modules 50 at different heights, or when the test process does not require projection, the frame 32 can be lowered to a lower position to prevent the frame 32 and the imaging film 34 thereon from blocking light.

[0061] The frame 32 is provided with a locking member 323, which is used to lock the frame 32 at a desired height. The locking member 323 has a first state for locking the frame 32 and a second state for releasing the frame 32. For example, the locking member 323 can be a screw or a bolt, and the locking member 323 is penetrated through the frame 32 and is arranged perpendicular to the through passage. When the locking member 323 is in the second state, the frame 32 can slide freely. When the frame 32 slides to the desired position, the locking member 323 is switched to the first state to lock the frame 32 at the desired height.

[0062] Reference Figures 6 to 8The third supporting structure in the tester installation mechanism 40 includes a base 41 and a tray 44. The base 41 includes a horizontal plate 411 and a vertical plate 412. The vertical plate 412 is arranged at one end of the horizontal plate 411 and is bent with the horizontal plate 411. The tray 44 is configured to be able to slide vertically along the vertical plate 412, and the carrier 42 is movably arranged on the tray 44. During testing, the tester 43 is installed on the carrier 42. Since the carrier 42 can be movably arranged on the tray 44 laterally, and the tray 44 can be movably arranged on the vertical plate 412 of the base 41, the tester is allowed to flexibly adjust the horizontal and vertical positions of the tester 43, so that the tester 43 can be moved to different positions to obtain the image displayed by the PGU module 50 or the light transmitted.

[0063] Specifically, the vertical plate 412 is provided with a slide groove 4121 extending in the vertical direction, and the tray 44 includes a receiving portion 441 and a sliding portion 442. The sliding portion 442 is provided at one end of the receiving portion 441 and is bent with the receiving portion 441. The sliding portion 442 is at least partially embedded in the slide groove 4121. The tray 44 slides up and down under the guidance of the slide groove 4121, which can prevent the tray 44 from shifting during the up and down movement. Then, the carrier 42 is movably provided on the receiving portion 441.

[0064] In order to fix the position of the tray 44, a plurality of first positioning holes 4122 are provided on the bottom wall of the slide groove 4121, and the plurality of first positioning holes 4122 are arranged at intervals in the length direction of the slide groove 4121. A second positioning hole 4421 is provided on the sliding portion 442, and a first fastener 4422 is passed through the second positioning hole 4421. When the sliding portion 442 slides to the desired position, the first fastener 4422 is inserted into the first positioning hole 4122 to lock the tray 44 and the vertical plate 412.

[0065] In order to realize the lateral movement of the tester 43, a sliding channel 4411 is recessed on the receiving portion 441, and the length direction of the sliding channel 4411 is set at an angle with the direction of the connection between the slide mounting mechanism 30 and the tester mounting mechanism 40, and the carrier plate 42 is slidably set in the sliding channel 4411. Therefore, the sliding of the carrier plate 42 will drive the tester 43 thereon to move, thereby realizing the adjustment of the lateral position of the tester 43.

[0066] In order to fix the position of the carrier 42, a plurality of third positioning holes 4412 are provided on the bottom wall of the sliding channel 4411, and the plurality of third positioning holes 4412 are arranged at intervals in the length direction of the sliding channel 4411. A fourth positioning hole 421 is provided on the carrier 42, and a second fastener 422 is passed through the fourth positioning hole 421. When the carrier 42 slides to the desired position, the second fastener 422 is inserted into the third positioning hole 4412 to lock the carrier 42 and the tray 44.

[0067] In some embodiments of the present invention, the tray 44 is configured to have an adjustable tilt angle, so that the tester 43 can obtain the image displayed by the slide mounting mechanism 30 or the transmitted light from different angles.

[0068] In one embodiment, the tester installation mechanism 40 further includes a lifting mechanism, which includes a first lifting rod and a second lifting rod disposed below the tray 44, wherein the first lifting rod is connected to one end of the tray 44, and the second lifting rod is connected to the other end of the tray 44. When the lifting heights of the first lifting rod and the second lifting rod are consistent, the tray 44 is lifted and lowered, and when the lifting heights of the first lifting rod and the second lifting rod are inconsistent, the tray 44 is tilted, so that the tester installation mechanism 40 can adapt to the test requirements of the PGU modules 50 of different heights and angles, thereby improving the adaptability and flexibility of the PGU module test bench 100.

[0069] At this time, the base 41 includes a horizontal plate, a first vertical plate and a second vertical plate, the first vertical plate and the second vertical plate are relatively arranged at the two ends of the horizontal plate, the first vertical plate is provided with a first slide groove extending in the vertical direction, and the second vertical plate is provided with a second slide groove extending in the vertical direction. The tray 44 includes a receiving portion, a first sliding portion and a second sliding portion, the first sliding portion and the second sliding portion are relatively arranged at the two ends of the receiving portion and bent with the receiving portion, the first sliding portion is at least partially embedded in the first slide groove, and the second sliding portion is at least partially embedded in the second slide groove. The first sliding portion and the second sliding portion of the tray 44 are respectively embedded in the first slide groove and the second slide groove, which can ensure that the tray 44 will not be offset in the horizontal direction during the process of adjusting the height and adjusting the tilt angle.

[0070] We know that the imaging focal lengths of different PGU modules 50 are not the same. In order to enable the PGU module test bench 100 to adapt to the imaging requirements of different PGU modules 50 and improve the flexibility of the PGU module test bench 100, some embodiments of the PGU module test bench 100 also include a guide rail 10, and the PGU module mounting mechanism 20, the slide mounting mechanism 30 and the tester mounting mechanism 40 are all slidably set on the guide rail 10, thereby allowing the tester to easily adjust the distance between the three.

[0071] In addition, the guide rail 10 has a first end and a second end, and the PGU module mounting mechanism 20, the slide mounting mechanism 30 and the tester mounting mechanism 40 are all slidably set on the guide rail 10, and can slide out from the first end or the second end, so as to facilitate the removal of the PGU module mounting mechanism 20, the slide mounting mechanism 30 and the tester mounting mechanism 40 from the guide rail 10, and facilitate the modular transfer of the PGU module mounting mechanism 20, the slide mounting mechanism 30, the tester mounting mechanism 40 and the guide rail 10 to another location for further assembly, thereby improving the portability of the PGU module test bench 100.

[0072] Specifically, a first sliding member 11, a second sliding member 12 and a third sliding member 13 are slidably arranged on the guide rail 10, a PGU module mounting mechanism 20 is mounted on the first sliding member 11, a slide mounting mechanism 30 is mounted on the second sliding member 12, and a tester mounting mechanism 40 is mounted on the third sliding member 13. The PGU module mounting mechanism 20, the slide mounting mechanism 30 and the tester mounting mechanism 40 are slidably arranged on the guide rail 10 by sliding members, respectively, so that the tester can easily move each mechanism, and conveniently perform the focal length joint adjustment test of the three.

[0073] Each sliding member is provided with a locking member, which is used to fix the corresponding sliding member at a desired position. The locking member can be a screw or a snap member 2212, etc., which has a first state for locking the sliding member and a second state for releasing the frame 32. When the locking member is in the second state, the sliding member can slide freely. When the sliding member slides to the desired position, the locking member is switched to the first state to fix the sliding member at the desired position.

[0074] Among them, scale lines are set on the guide rail 10, and the scale lines facilitate the tester to accurately adjust the positions of the PGU module mounting mechanism 20, the slide mounting mechanism 30 and the tester mounting mechanism 40, so as to achieve precise focusing.

All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
