Detailed Description
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
Unless defined otherwise, all technical terms used in the embodiments of the present application have the same meaning as commonly understood by one of ordinary skill in the art.
In order to make the technical scheme and advantages of the present application more apparent, embodiments of the present application will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1, an embodiment of the present application provides a testing device including a stand assembly 100 and a light transmitting member 200. The bracket assembly 100 is used for carrying a head-up display 300 to be tested. The bracket assembly 100 has a first marking location 400 and a second marking location 500 thereon. It should be noted that, when the testing device provided by the embodiment of the present application is used for testing, the head-up display 300 to be tested is in a working state, and the testing device needs to be placed in a region with sufficient sunlight and no shielding, so as to ensure that the sunlight can be injected into the head-up display 300 to be tested. The light-transmitting member 200 shown in the drawings of the present application is only a part of the light-transmitting member 200, and the size of the light-transmitting member 200 can be adjusted according to the need. The image source of the head-up display 300 to be tested is projected and displayed on the transparent member 200 after being enlarged, so that the imaging change can be observed through the transparent member 200, and the performance change of the head-up display 300 to be tested can be further known.
The light transmitting member 200 is connected to the bracket assembly 100, and the head-up display 300 to be tested is located between the bracket assembly 100 and the light transmitting member 200, so that sunlight can be injected into the head-up display 300 to be tested through the bracket assembly 100 to simulate the sunlight backflow process. The shadow formed by the sunlight irradiated on the first mark position 400 falls on the second mark position 500, and the connection line between the first mark position 400 and the second mark position 500 is parallel to the main optical axis in the imaging optical path of the head-up display 300 to be tested. It should be noted that, when the head-up display 300 to be tested is in the working state, the light beam propagating along the main optical axis generally exits from the center of the image generating unit of the head-up display and falls on the windshield glass of the vehicle, and the line between the first mark position 400 and the second position is parallel to the main optical axis in the imaging optical path of the head-up display 300 to be tested, so according to the principle of reversibility of the optical path, if the shadow of the first mark position 400 can fall on the second mark position 500, it can be ensured that the light spot formed by converging sunlight through the curved mirror of the head-up display 300 to be tested at this time falls on the center of the image display. The sunlight can be irradiated to the first marking position 400 through the light-transmitting member 200, or can be directly irradiated to the first marking position 400 without passing through the light-transmitting member 200. The main optical axis is a propagation path formed by the central light ray among all the light paths that can be imaged on the windshield. That is, the tester can adjust the position of the bracket assembly 100 at any time by observing whether the shadow of the first mark position 400 falls on the second mark position 500, so that the shadow of the first mark position 400 always falls on the second mark position 500, thereby more accurately simulating the sunlight backflow scene corresponding to the head-up display 300 to be tested when the temperature rise is fastest, ensuring that the light spot can be always located at the center of the image generating unit, and improving the accuracy and the test efficiency of the sunlight backflow test result.
It should be noted that, the test device generally needs to be modeled before the preparation, and the first marker position 400 and the second marker position 500 in the embodiment of the present application are predetermined in the modeling process, where the determining process includes that a model corresponding to the test device on which the head-up display 300 to be tested is installed is first built, a main optical axis of the known head-up display 300 to be tested is obtained, and the main optical axes are parallel until two intersection points are generated with the bracket assembly 100. Finally, when the real object of the test device is manufactured according to the model, the two intersection points determined in the model can be directly used as the first marking position 400 and the second marking position 500 which correspond to the real object respectively.
The details and functions of the test device according to the embodiments of the present application will be described in more detail with reference to fig. 1 to 6.
As shown in connection with fig. 2 and 3, in some embodiments, the bracket assembly 100 includes a base 110 and a support assembly 120. The head-up display 300 to be tested is located on the base 110. It should be noted that, the head-up display 300 to be tested may be mounted on the base 110 by being snapped into the mounting hole on the base 110, and may be fixed on the base 110 by a fixing member such as a bolt, and may be adhered to the base 110 by an adhesive member, and may be snapped onto the base 110 by a clipping member, so long as the head-up display 300 to be tested may be fixed on the base 110.
One side of the supporting member 120 is connected to the base 110, the other side of the supporting member 120 extends in a direction away from the base 110, and the supporting member 120 is connected to the light-transmitting member 200. So that the light-transmitting member 200 can be stably coupled with the base 110.
As shown in fig. 2, in some embodiments, the support assembly 120 includes a support plate 121, a first support column 122, and a second support column 123. One end of the supporting plate 121 is connected with the base 110, the other end of the supporting plate 121 extends towards the direction away from the base 110, and a first clamping groove 124 is formed in the surface of the supporting plate 121 facing the head up display 300 to be tested.
The first support column 122 is arranged opposite to the second support column 123, the first support column 122 and the second support column 123 are respectively connected with the base 110, a second clamping groove 125 is formed in the surface of the first support column 122 facing the head up display 300 to be tested, and a third clamping groove 129 is formed in the surface of the second support column 123 facing the head up display 300 to be tested.
The light-transmitting member 200 includes a first side 210, a second side 220 and a third side 230, which are sequentially connected, where the first side 210 and the third side 230 are opposite to each other, the second side 220 is clamped into the first slot 124, and the first side 210 and the third side 230 are respectively clamped into the second slot 125 and the third slot 129. So that the light-transmitting member 200 can be stably coupled with the support assembly 120.
As shown in connection with fig. 2, in some embodiments, the height between the second card slot 125 and the base 110 is equal to the height between the third card slot 129 and the base 110. The height between the first clamping groove 124 and the base 110 is lower than the height between the second clamping groove 125 and the base 110. By the arrangement, when each side edge of the light-transmitting piece 200 is respectively clamped into the corresponding clamping groove, the light-transmitting piece 200 can be made to be an inclined surface, so that a scene that sunlight penetrates through the windshield glass of the vehicle in a real scene can be more truly simulated. In some embodiments, the material and the inclination angle of the light transmissive member 200 are the same as the material and the inclination angle of the windshield of the target vehicle, respectively. Therefore, the sunshine backflow scene can be simulated more truly, and the accuracy of the test result is improved.
As shown in connection with fig. 1 and 2, in some embodiments, a first marking location 400 is provided on the first support column 122 and a second marking location 500 is provided on the base 110. Thereby facilitating the tester to observe the propagation of the light irradiated to the first mark location 400.
In some embodiments, two first marking positions 400 are provided on the first support column 122, two second marking positions 500 are provided on the base 110, and the first marking positions 400 and the second marking positions 500 are in one-to-one correspondence. In this way, only when the two first marking positions 400 respectively fall on the corresponding second marking positions 500, the adjustment of the bracket assembly 100 is stopped, so that the head-up display 300 to be tested is kept at the current angle, and the angle of the head-up display 300 to be tested can be adjusted more accurately, thereby improving the accuracy of the test result.
As shown in fig. 4, in some embodiments, the first support column 122 is provided with a raised portion 126, with the apex of the raised portion 126 forming a first marker location 400. It should be noted that, according to the principle of shadow formation, by setting the protruding portion 126, when sunlight irradiates on the vertex of the protruding portion 126, the shadow of the vertex can fall on the base 110 more obviously, so that a tester can distinguish and determine the shadow position of the vertex, the first support column 122 and the shadow position of any point on the protruding portion 126, thereby improving the efficiency and accuracy of observing the shadow position of the first mark position 400, ensuring that the light spot can be always located at the center of the image generating unit, and further improving the accuracy of the test result.
As shown in fig. 5, in some embodiments, a surface of the first support column 122 facing the head-up display 300 to be tested is provided with a through groove 127, and the through groove 127 extends in a direction perpendicular to the first support column 122. Any slot top end 128 of the through slot 127, which is far away from the support plate 121, is a first marking position 400, and a second marking position 500 corresponding to the first marking position 400 is provided on the base 110. It should be noted that, according to the principle of shadow formation, by taking any slot top end 128 of the through slot 127 far away from the support plate 121 as the first mark position 400, after the sunlight irradiates on any slot top end 128, the shadow of the slot top end 128 can more obviously fall on the base 110, so that the test personnel can more conveniently distinguish and judge the shadow positions of the slot top end 128, the first support column 122 and the shadow positions of other points on the through slot 127, thereby improving the efficiency and accuracy of observing the shadow positions of the first mark position 400, ensuring that the light spot can be always located at the center of the image generating unit, and further improving the accuracy of the test result.
As shown in fig. 5, in some embodiments, the second marker position 500 is formed with a groove 510. It will be appreciated that when the shadow of the first mark position 400 falls within the groove 510, i.e. the spot is considered to be at the center of the image generation unit, the groove 510 is arranged to facilitate the observation of the shadow position of the first mark position 400 by a tester.
In some embodiments, as shown in fig. 5, the orthographic projection of the groove 510 on the plane of the base 110 is a circle, and the diameter of the circle is not less than 2mm and not more than 6mm. By the arrangement, the shadow of the first mark position 400 can be ensured to accurately fall on the second mark position 500, and the observation error caused by the overlarge diameter of the groove 510 can be reduced, so that a tester can accurately adjust the bracket assembly 100, namely, the position and the angle of the head-up display 300 to be tested.
As shown in fig. 6, in some embodiments, the bracket assembly 100 further includes a mount 130. The mount 130 includes opposing first and second sidewalls 131, 132. The base 110 includes a bottom wall 111, a first mounting portion 112, and a second mounting portion (not shown in the drawings), one end of the first mounting portion 112 and one end of the second mounting portion are respectively connected to the bottom wall 111 and extend in a direction away from the bottom wall 111. The first mounting portion 112 is connected to a portion of the first bolt 800, and another portion of the first bolt 800 is rotatably connected to the first side wall 131, for example, another portion of the first bolt 800 is rotatably clamped in a groove formed in the first side wall 131. The second mounting portion is coupled to a portion of a second bolt (not shown) and another portion of the second bolt is rotatably coupled to the first sidewall 131. The first bolt 800 is coaxial with the second bolt. So that the base 110 can rotate with respect to the mount 130 about the axial direction of the first bolt 800. The connection between the second mounting portion, the second bolt, and the second side wall is the same as the connection between the first mounting portion 112, the first bolt 800, and the first side wall 132.
As shown in fig. 3, in some embodiments, a rotation mechanism 1000 is disposed in the mounting base 130, where the rotation mechanism 1000 is rotatably connected to the base 110, and when the rotation mechanism 1000 rotates, the base 110 can be driven to rotate around the axial direction of the first bolt 800. It can be appreciated that when the base 110 rotates relative to the mounting base 130, the head-up display 300 to be tested mounted on the base 110 also rotates synchronously with the base 110, so that the angle of the head-up display 300 to be tested can be adjusted more flexibly. It should be noted that, the rotation mechanism 1000 may be a screw mechanism, and the screw mechanism generally includes a screw 1010 and a guide block 1020, where the guide block 1020 may be rotatably connected to the base 110. For example, the guide block 1020 may be movably caught in the U-shaped groove 115 of the connection plate 114 connected to the bottom of the base 110 by a bolt. It can be appreciated that when the screw 1010 rotates to drive the guide block 1020 to move along the axial direction of the screw 1010, the guide block 1020 can drive the connecting plate 114 to rotate, and further drive the base 110 to rotate around the axial direction of the first bolt 800, so that the angle of the head-up display 300 to be tested can be flexibly adjusted, and the testing efficiency is improved.
As shown in fig. 3, in some embodiments, the testing device further includes a carrier 600 and a rotating shaft 700, and both ends of the rotating shaft 700 are respectively connected to the carrier 600 and the bracket assembly 100, and the bracket assembly 100 can rotate around the rotating shaft 700 relative to the carrier 600. It can be appreciated that, by rotating the bracket assembly 100 around the rotation axis 700, the head-up display 300 to be tested connected to the bracket assembly 100 can be driven to rotate synchronously, so that the angle of the head-up display 300 to be tested can be adjusted more flexibly, and the testing efficiency of the sunlight backflow test is improved.
As shown in fig. 3, in some embodiments, the testing device further comprises at least two adjusting columns 1100, wherein the adjusting columns 1100 have a flexibility, one end of each adjusting column 1100 is connected to a side of the carrier 600 facing away from the base 110, and the other end of each adjusting column 1100 is adapted to be placed on the ground or other platform of the testing device. It should be noted that, by adjusting the height of the end of each adjusting column 1100 near the base 110 relative to the ground or between the platforms for preventing the testing device, the carrier 600 can be adjusted to be in a horizontal state, so that the mounting base 130 can be ensured to be in a horizontal state, the mounting base 130 is prevented from tilting, and the stability of the testing device during the testing process is improved.
As shown in fig. 3, in some embodiments, a level 1200 is mounted on the mount 130. It will be appreciated that when adjusting the adjustment column 1100, the level of the mounting base 130 can be adjusted more conveniently by observing the state of the level 1200 to see whether the current mounting base 130 is in a level state.
As shown in fig. 3, in some embodiments, the number of heads-up displays 300 to be tested is two, and two heads-up displays 300 to be tested are mounted side by side on the base 110. The two head-up displays 300 to be tested synchronously rotate along with the base 110, and the placement angles of the two head-up displays are the same, so that the test requirements of a comparison test can be met, different test requirements can be met by the test device, and the practicability of the test device is improved. Generally, the heat dissipation components or optical elements, etc., inside the two heads-up display 300 to be tested are slightly different. It should be noted that, when the testing device provided by the embodiment of the present application is utilized, sunlight is converged through the curved mirrors of the head-up display 300 to be tested to form light spots, and then the light spots fall at the centers of the image generating units of the corresponding head-up displays. It can be appreciated that, by comparing the test results of the two heads-up display 300 to be tested, the structure of the heads-up display 300 to be tested can be further improved, so as to improve the usability of the heads-up display 300 to be tested.
