Description

Technical Field

[0001] This utility model relates to the field of central control screen testing technology, and in particular to a test bench for automotive central control screens. Background Technology

[0002] With the automotive industry's profound transformation towards intelligence and connectivity, the central control display screen has evolved from a traditional entertainment and navigation unit into a core human-machine interface (HMI) integrating vehicle control, infotainment, advanced driver assistance systems (ADAS) display, and even artificial intelligence interaction. Its functional integration, software complexity, and hardware performance requirements have reached unprecedented levels. Therefore, comprehensive and rigorous R&D and factory testing of the central control screen is a crucial step in ensuring overall vehicle quality and user experience, and test benches are indispensable basic platform equipment for performing these testing tasks.

[0003] In existing technologies, test benches used for central control screens typically employ a relatively fixed structural design. The main body is generally a metal or wooden workbench with a standard working height, and fixed mounting plates or mounting holes are provided on the surface. When fixing the central control screen to be tested, operators mostly use manual universal clamps, bolt tightening, or specially designed and manufactured brackets for a specific car model's screen. During testing, the central control screen must be manually placed in the mounting area, and then tools are used to adjust the clamps or tighten the screws one by one to fix it on the test bench. Then, various test harnesses and equipment are connected. The technical principle relies on purely mechanical rigid connections and manual operation.

[0004] However, the traditional technical solutions relying on manual operation and dedicated fixtures have revealed serious limitations in the face of the rapid iteration and diversification of central control screens in current intelligent connected vehicles. As major automakers accelerate the launch of new models, the design of central control screens is showing a trend towards larger sizes, irregular shapes, and greater diversity. A single test bench often needs to be compatible with dozens of screens of different sizes and shapes. At this point, traditional test benches, due to their fixed mounting platform positions and single clamping methods, suffer from extremely low versatility and operational efficiency. Every time a new model of central control screen is replaced, testers must spend a significant amount of time finding, replacing, or even remaking matching fixtures. Furthermore, the manual clamping process is not only cumbersome and time-consuming but also carries the risk of scratching the screen frame or damaging the screen due to uneven force or improper operation. Therefore, a new automotive central control screen test bench is proposed to address these problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a test bench for automotive central control screens, aiming to improve upon the limitations of traditional test benches whose fixing fixtures are ill-suited to the diverse and irregular shapes of modern central control screens. This results in inefficiency and cumbersome operation when changing models, and poses a risk of screen damage. This invention addresses the problems of poor versatility and inconvenient clamping.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a test bench for automotive central control screens, including a workbench, a storage cabinet installed inside the workbench, a support cabinet fixedly connected to the upper surface of the workbench, multiple placement plates installed on the outer wall of the support cabinet, and positioning components installed on the outer wall of the placement plates. The positioning assembly includes a first fixing plate, one side of which is fixedly connected to a corner of a placement plate. Multiple second fixing plates are fixedly connected to one side of the first fixing plate, and limit rods are fixedly connected between the second fixing plates. An electric actuator is fixedly connected to one side of the first fixing plate, and a connecting plate is fixedly connected to the output end of the electric actuator. A symmetrical L-shaped plate is fixedly connected to one side of the connecting plate, and the L-shaped plate is slidably connected to the limit rod inside. Multiple mounting blocks are fixedly connected to one side of the connecting plate, and silicone wheels are rotatably connected inside the mounting blocks. A limit rail is fixedly connected to one side of the worktable.

[0007] As a further description of the above technical solution: The outer wall of the limiting slide rail is slidably connected to multiple sliders, and the outer wall of each slider is fixedly connected to a corner protector.

[0008] As a further description of the above technical solution: A fixed cylinder is fixedly connected to the outer wall of the slider, and a sliding plate is slidably connected inside the fixed cylinder.

[0009] As a further description of the above technical solution: A locking block is fixedly connected to one side of the outer wall of the sliding plate, and a sliding rod is fixedly connected to the other side of the outer wall of the sliding plate.

[0010] As a further description of the above technical solution: A spring is fitted on the outer wall of the slide rod, and the outer wall of the locking block passes through the slider and is slidably connected to the inner wall of the limiting slide rail. One end of the spring is fixedly connected to one side of the inner wall of the fixed cylinder, and the other end of the spring is fixedly connected to one side of the outer wall of the sliding plate.

[0011] As a further description of the above technical solution: A fixed slide rail is fixedly connected to one side of the outer wall of the support cabinet, and a sliding block is slidably connected to the outer wall of the fixed slide rail.

[0012] As a further description of the above technical solution: A rotating frame one is rotatably connected to one side of the outer wall of the sliding block, and a rotating frame two is rotatably connected to one side of the outer wall of the rotating frame one.

[0013] As a further description of the above technical solution: The outer wall of the rotating frame is rotatably connected to a hinge seat, and one side of the outer wall of the hinge seat is fixedly connected to one side of the outer wall of the placement plate.

[0014] This utility model has the following beneficial effects: 1. In this utility model, the fixed slide rail, sliding block, and the linkage structure of rotating frame one and rotating frame two set on the support cabinet enable flexible adjustment of the overall position and height of the placement plate to adapt to different testing scenarios and improve the convenience of human-computer interaction. Simultaneously, by activating the electric actuator to drive the L-shaped plate with silicone wheels to move along the limiting rod, it is possible to quickly, stably, and without damage automatically clamp and position automotive central control screens of different sizes. This design not only greatly improves the compatibility and adaptability to products under test of different specifications but also ensures stability during the testing process, improving the level of automation and testing efficiency.

[0015] 2. In this utility model, an adjustable protective system is constructed by using a limiting slide rail set on the edge of the workbench and corner guards that can slide on it and are locked by a locking block and a spring. Operators can freely adjust the position of the corner guards according to the size of the device under test or the required operating space, effectively preventing accidental collisions caused by personnel movement or equipment handling during testing, thus protecting the safety of the test bench and the device under test. Furthermore, the storage cabinet inside the workbench provides centralized storage space for testing tools and related accessories, making the working environment more tidy and organized, further enhancing the overall practicality and safety of the test bench.

[0018] 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.

[0019] Reference Figure 1 - Figure 5 The present invention provides an embodiment of a test bench for automotive central control screens, comprising a workbench 1 that serves as the foundation of the overall structure and provides a stable operating plane, a storage cabinet 2 for storing test tools and accessories and keeping the work area tidy, a support cabinet 3 for raising the operating plane and serving as the mounting base for core components that is fixedly connected to the upper surface of the workbench 1, and multiple placement plates 4 for directly supporting the central control screen to be tested installed on the outer wall of the support cabinet 3, and positioning components for automatically clamping and fixing the central control screen installed on the outer wall of the placement plates 4. The positioning assembly includes a fixing plate 5 serving as its mounting base. One side of the outer wall of the fixing plate 5 is fixedly connected to a corner of the placement plate 4. Multiple fixing plates 6 for supporting guide rails are fixedly connected to one side of the outer wall of the fixing plate 5. Limiting rods 7 for providing stable motion guidance for the clamping mechanism are fixedly connected between the multiple fixing plates 6. An electric push rod 8 for providing automatic clamping power is fixedly connected to one side of the outer wall of the fixing plate 5. A connecting plate 9 for transmitting thrust is fixedly connected to the output end of the electric push rod 8. A symmetrical L-shaped plate 10 for symmetrical clamping is fixedly connected to one side of the outer wall of the connecting plate 9. The interior of the L-shaped plate 10 is slidably connected to the limiting rod 7 to ensure its smooth movement. Multiple mounting blocks 11 serving as roller mounting seats are also fixedly connected to one side of the outer wall of the connecting plate 9. Silicone wheels 12 that flexibly contact the screen and prevent scratches are rotatably connected inside the mounting blocks 11. A limiting slide rail 13 for mounting adjustable protective components is fixedly connected to one side of the outer wall of the worktable 1.

[0020] Specifically, the electric actuator 8 provides power to drive the L-shaped plate 10 to move precisely in a straight line along the limiting rod 7, thereby achieving symmetrical and centered clamping of central control screens of different sizes. The design of the silicone wheel 12 ensures that the contact during the clamping process is flexible, providing sufficient friction for a stable fixation while effectively avoiding any scratches or damage to the expensive central control screen surface.

[0021] Reference Figure 1 - Figure 5 The outer wall of the limiting slide rail 13 is slidably connected to multiple sliders 15, which serve as bases for movable protective units. Corner blocks 14 are fixedly connected to the outer wall of each slider 15 to prevent accidental collisions. A fixed cylinder 16, which houses the locking mechanism, is also fixedly connected to the outer wall of each slider 15. A sliding plate 17, serving as the moving body of the locking mechanism, is slidably connected inside the fixed cylinder 16. A locking block 18 is fixedly connected to one side of the outer wall of the sliding plate 17, and a sliding rod 19, which is pulled by the operator to unlock, is fixedly connected to the other side of the outer wall of the sliding plate 17. A spring 20, providing automatic reset locking force, is sleeved on the outer wall of the sliding rod 19. The outer wall of the locking block 18 can penetrate the slider 15 and slidably connect to the inner wall of the limiting slide rail 13 to achieve position fixation. One end of the spring 20 is fixed. One end of the fixed cylinder 16 is connected to the inner wall of the fixed cylinder 16, and the other end is fixedly connected to the outer wall of the sliding plate 17, thereby continuously applying a locking force to the locking block 18; one side of the outer wall of the support cabinet 3 is fixedly connected to a fixed slide rail 21 for vertical or horizontal movement, and the outer wall of the fixed slide rail 21 is slidably connected to a sliding block 22, which serves as the base for the entire adjusting arm; one side of the outer wall of the sliding block 22 is rotatably connected to a rotating frame 1 23, which serves as the first section of the adjusting arm, and one side of the outer wall of the rotating frame 1 23 is rotatably connected to a rotating frame 24, which serves as the second section of the adjusting arm; the outer wall of the rotating frame 24 is rotatably connected to a hinge seat 25, which serves as the final connection platform, and one side of the outer wall of the hinge seat 25 is fixedly connected to the outer wall of the placement plate 4, thereby giving the adjustment capability to the placement plate 4.

[0022] Specifically, the multi-degree-of-freedom adjusting arm, consisting of a fixed slide rail 21, a sliding block 22, and two rotating frames 23 and 24, allows the placement plate 4 supporting the central control screen to be adjusted in all directions to adapt to different testing needs and operator habits. The corner guards 14, consisting of a limit slide rail 13 and a built-in self-locking mechanism, form a movable protective system that can be flexibly arranged as needed to effectively protect the equipment.

[0023] Working principle: When the device is needed, first adjust the position of the placement plate 4 according to the size of the central control screen to be tested or personal operating habits. By manually moving the sliding block 22 that cooperates with the fixed slide rail 21 on the support cabinet 3, and rotating the hinged rotating frame 1 23 and rotating frame 24, the overall height and front and rear position of the placement plate 4 can be flexibly set to achieve the best test posture. After the position is adjusted, place the car central control screen to be tested on the placement plate 4. Then, start the electric push rod 8 in the positioning component. The output end of the electric push rod 8 will push the connecting plate 9, which will drive the left and right symmetrical L-shaped plates 10 to move towards each other along the limit rod 7. The multiple silicone wheels 12 on the L-shaped plate 10 will gently contact and clamp the central control screen from both sides until it is firmly fixed in the center position of the placement plate 4, completing the automated rapid positioning and clamping. During testing, to protect the test bench and equipment from accidental collisions, the operator can adjust the corner protectors 14 on the edge of the workbench 1. By pressing down the slide bar 19, the sliding plate 17 is moved, causing the locking block 18 to disengage from the inner wall of the limiting slide rail 13. At this time, the corner protector 14 can be freely slid to the appropriate position. After releasing the slide bar 19, the elastic force of the spring 20 will cause the locking block 18 to reset and re-lock into the inner wall of the limiting slide rail 13, thereby locking the corner protector 14. In addition, the tools and accessories required for testing can be stored in the storage cabinet 2 inside the workbench 1 for easy access and to keep the working environment clean and orderly.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
