Description

Technical Field

[0001] This utility model relates to the field of automotive parts testing technology, and in particular to a portable head-up display test bench. Background Technology

[0002] A head-up display (HUD) is a multi-functional instrument panel centered on the driver and operated blindly. It projects important driving information, such as speed and navigation, onto the windshield in front of the driver, keeping them looking up. This avoids the safety hazards caused by looking down at the instrument panel, navigation system, or other driver assistance devices, and also reduces eye strain from alternating between looking at objects at different distances inside and outside the vehicle.

[0003] Before going live, HUDs require performance testing. The current method involves building a simple stand with a tilted glass panel on it to simulate a windshield. The HUD to be tested is then placed below the glass, projecting its image onto the surface. A camera captures the projected image, and analysis of this image yields the HUD's performance parameters. However, different field of view (FOV) requirements necessitate different angles for the optical path board and the windshield. Each test requires the fabrication of a complete head-up display and demonstration stand, resulting in wasted product prototyping time and increased overall product cost.

[0004] In response, CN115183101A discloses a head-up display testing device. For the support of the windshield, it is necessary to use a windshield support component in conjunction with an angle adjustment component to adjust the angle of the windshield. Based on this structure, when it is necessary to change the platform, there are problems such as inconvenience in carrying and the need to assemble multiple components, resulting in poor usability.

[0005] Therefore, the overall structure of the testing device needs further optimization to achieve portability and ease of use. Utility Model Content

[0006] The purpose of this invention is to provide a portable head-up display test stand to solve the technical problem of balancing structural simplification with the requirement for adjustable support angle for the windshield.

[0017] The sidewalls of the U-shaped openings of the support columns at the two end corners of the glass slide relative to the lower end of the test platform have anti-detachment walls that abut against the side edges of the glass slide.

[0018] In an optional embodiment of this invention, the fixing column has a hollow receiving cavity suitable for insertion of the supporting column portion;

[0019] The fixing column has a plurality of fixing holes spaced longitudinally along a direction perpendicular to the test platform on at least one side wall, and the support column has at least one connecting hole adapted to mate with one of the fixing holes in a one-to-one manner; the connecting hole is adapted to be connected to the corresponding fixing hole by a fastener.

[0020] In an optional embodiment of this invention, the fastener is a screw, and the connecting hole is adapted to engage with the fastener thread.

[0021] In an optional embodiment of this utility model, the fixing hole is provided on each of a pair of opposite sidewalls of the fixing column; and

[0022] The fixing holes on the pair of side walls of the fixing column correspond one-to-one;

[0023] When the support column and the fixed column are assembled in place by fasteners, a connector is adapted to pass through a pair of fixing holes located on a pair of side walls of the fixed column adjacent to the bottom end of the support column, so that the connector forms a bottom support for the support column.

Therefore, this utility model, while meeting the testing requirements for HUDs, has a simple overall structure, is easy to carry, and can adaptively adjust the support height and angle according to the needs of different HUDs, making it convenient to use.

Detailed Implementation

[0039] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0040] Please see Figures 1 to 6 As shown, this embodiment provides a portable head-up display test stand, including: a support base plate, and a head-up display fixing assembly and a glass support assembly disposed on the support base plate.

[0041] The support base plate is roughly flat and has a test platform 1, which provides space for the layout of the head-up display (HUD) mounting components and the glass support components. Furthermore, multiple fastening holes 11 are arrayed on the test platform 1. Each fastening hole 11 can be used to fasten the HUD mounting components and the glass support components. By adjusting the engagement of the HUD mounting components and the glass support components with different fastening holes 11, their specific layout positions on the test platform 1 can be adjusted.

[0042] Next, in detail, firstly, the head-up display (HUD) mounting assembly includes at least three spaced-apart support frames detachably mounted on the test platform 1 for supporting the HUD 6; each support frame is adapted to adjust its longitudinal height relative to the test platform 1. This embodiment is described with reference to the accompanying drawings, using a three-support-frame design as an example, where the three support frames can be roughly distributed to form a triangular structure.

[0043] More specifically, each support frame includes a fixed frame 21 connected to the test platform 1 and a support frame 22 connected to the fixed frame 21 for supporting the head-up display 6. The fixed frame 21 has a hollow assembly cavity suitable for partial insertion of the support frame 22. Each support frame 22 has a support head 221 formed at its end away from the fixed frame 21 for supporting and fixing the head-up display 6. The fixed frame 21 is equipped with a connecting seat for connection to any of the fastening holes 11.

[0044] Based on the above structure, furthermore, at least one limiting hole 211 is provided on one side wall of the fixing frame 21 at longitudinal intervals perpendicular to the test platform 1; and multiple limiting grooves 222 are provided on the side wall of the support frame 22 at longitudinal intervals perpendicular to the test platform 1 corresponding to the limiting hole 211. Each limiting hole 211 is adapted to mate with a limiting member 23, and each limiting member 23 extends through the limiting hole 211 and into the assembly cavity to be embedded in one of the limiting grooves 222. The limiting member 23 here may be, for example, but not limited to, a pin, and each pin is adapted to have its end extending into the assembly cavity formed into a pointed tip to facilitate embedding into the limiting groove 222. Here, the position between the support frame 22 and the fixing frame 21 is defined by the cooperation of the limiting member 23, the limiting hole 211, and the limiting groove 222.

[0045] Secondly, the glass support assembly includes at least four spaced columns detachably mounted on the test platform 1; each column is adapted to adjust its longitudinal height relative to the test platform 1, and the longitudinal height of each column relative to the test platform 1 is greater than the longitudinal height of each support frame relative to the test platform 1; and all four columns are located circumferentially outside the head-up display fixing assembly. Under this structure, the glass sheet 5 can be positioned above the head-up display 6 under the action of the glass support assembly.

[0046] Based on the above structure, this embodiment will be described in conjunction with the accompanying drawings, taking the case where the glass support assembly includes four columns adapted to support the four corners of a rectangular glass sheet 5 as an example:

[0047] Each column includes a fixed column 41 connected to the test platform 1 and a support column 42 connected to the fixed column 41 for supporting the glass plate 5; each support column 42 has a limiting groove 222 at its end away from the fixed column 41 for fitting the glass plate 5. The fixed column 41 is equipped with a connecting seat 3 for connecting to any of the fastening holes 11.

[0048] Regarding the fit between the support column 42 and the glass plate 5:

[0049] Generally, each support column 42 has a limiting groove 222 with a U-shaped opening 421 facing the glass sheet 5; the glass sheet 5 is adapted to be inclined relative to the test platform 1 under the support of the four columns; taking the generally rectangular glass sheet 5 as an example, the longitudinal height supported by two columns relative to the test platform 1 is greater than the longitudinal height supported by the other two columns relative to the test platform 1. At this angle, the glass sheet 5 can be inclined to first insert into the U-shaped openings 421 of the two columns with higher longitudinal height, and then into the U-shaped openings 421 of the two columns with lower longitudinal height. Based on this, in order to prevent the inclined glass sheet 5 from sliding downwards, this embodiment also includes the following design:

[0050] The sidewalls of the U-shaped openings 421 of the support columns 42 at the two end corners of the glass plate 5 relative to the test platform 1 have anti-detachment walls 422 that abut against the side edges of the glass plate 5. That is, the two columns with smaller longitudinal heights are respectively provided with anti-detachment walls 422 for closing one side of the U-shaped openings 421 at the bottom edge of the inclined glass plate 5, thereby playing a role in preventing the glass plate 5 from slipping.

[0051] Next, we will explain the fit between the fixed column 41 and the support column 42:

[0052] The fixing post 41 has a hollow receiving cavity suitable for insertion into a portion of the support post 42; at least one side wall of the fixing post 41 is provided with a plurality of fixing holes 411 spaced longitudinally perpendicular to the test platform 1, and the support post 42 is provided with at least one connecting hole adapted to mate with one of the fixing holes 411 in a pair; the connecting hole is adapted to be connected to the corresponding fixing hole 411 by a fastener 43. The fastener 43 here is, for example, but not limited to, a screw, and the connecting hole is adapted to be threaded into the fastener 43.

[0053] Based on the above, in an optional implementation, to improve the reliability and stability of the structure formed by the overall support frame 22 and the fixing frame 21, this embodiment can also be designed as follows:

[0054] Each of the pair of opposing sidewalls of the fixing post 41 is provided with a fixing hole 411; and the fixing holes 411 on the pair of sidewalls of the fixing post 41 correspond one-to-one. When the support post 42 and the fixing post 41 are assembled into place by fasteners 43, a connector 44 is suitable to pass through the pair of fixing holes 411 located on the pair of sidewalls of the fixing post 41 adjacent to the bottom end of the support post 42, so that the connector 44 forms a bottom support for the support post 42. The connector 44 here can be a long screw, which can pass through the pair of fixing holes 411 on the pair of sidewalls of the positioning post at the same time, so that the end of the support post inserted into the receiving cavity can be fitted on the long screw, thereby consolidating the stable fit between the support post and the fixing post 41.

[0055] In summary, regarding the portable head-up display (HUD) test stand of this embodiment, for fixing the HUD, the support height and angle of the HUD 6 relative to the test platform 1 can be adjusted by adjusting the longitudinal height of each support frame relative to the test platform 1; similarly, for fixing the glass plate 5, the support height and angle of the glass plate 5 relative to the side wall platform can be adjusted by adjusting the longitudinal height of each column relative to the test platform 1. Therefore, this utility model, while meeting the testing requirements for the HUD 6, has a simple overall structure, is easy to carry, and can adaptively adjust the support height and angle according to the needs of different HUDs 6, making it convenient to use.
