[0001] The present invention relates to the technical field of automobile design and verification, and in particular to an automobile ergonomics driver verification device and system. Background Art

[0002] At present, the automotive design field is facing increasingly complex design requirements and a highly competitive market environment. Traditional automotive design verification methods have many problems, including long physical prototype production cycles, high costs, and incomplete design verification.

[0003] To solve these problems, virtual reality technology has been widely used in the field of automotive design. Through virtual simulation, virtual display and other technical means, designers can verify the design in a virtual environment, reduce the dependence on physical prototype production, and improve design efficiency and accuracy. However, the application of virtual reality technology in automotive design still has some limitations, such as motion tracking and image quality still need to be improved.

[0004] On the other hand, as an emerging design verification tool, automotive flexible test bench technology has brought new possibilities to automotive design. The flexible test bench of the main driver verification device can simulate the design status of the main driver area (including the main driver seat, main driver floor, steering wheel, chassis frame) of different models, providing designers with a more realistic and comprehensive design verification environment; however, traditional flexible test bench technology still has limitations in some aspects, such as insufficient flexibility and diversity, limited simulation accuracy, etc., and cannot meet the increasingly complex automotive design needs.

[0005] For example, patent CN118913710A discloses a device, system and method for automobile ergonomics verification suitable for combining virtual and real, wherein the device includes a test bench chassis mechanism, a ceiling block mechanism and an intelligent control unit, wherein a ceiling frame mechanism is arranged on the test bench chassis mechanism, and an installation space is provided between the test bench chassis mechanism and the ceiling frame mechanism; a steering wheel adjustment mechanism, a floor mechanism, an elbow pillow mechanism, a seat mechanism and a rear sill mechanism are arranged along the length direction in the installation space; the ceiling block mechanism is arranged on the ceiling frame mechanism, and is used to provide a light source for the virtual reality system; the intelligent control unit is used to obtain the tester's instructions, and adjust and control the test bench chassis mechanism, the ceiling frame mechanism, the steering wheel adjustment mechanism, the floor mechanism, the elbow pillow mechanism, the seat mechanism, the rear sill mechanism and the ceiling block mechanism according to the tester's instructions; it can only verify the design status of the main driving part.

The steering wheel XYZ adjustment mechanism is a three-way integrated adjustment module structure with a compact structure.

[0051] like Figures 6 to 10 As shown, the preferred solution for steering wheel adjustment is:

[0052] The steering wheel mechanism mainly includes three parts: an angle and axial adjustment mechanism 21, a connection and support mechanism 22, and an XYZ adjustment mechanism 23; the angle and axial adjustment mechanism 21 is connected to the support mechanism through bolts, and the connection and support mechanism 22 is connected to the XYZ adjustment mechanism 23 through slide rails.

The steering wheel Z-direction adjustment motor Ⅰ213 and the steering wheel Z-direction adjustment motor Ⅱ214 are used to drive the transmission coupling Ⅰ215 and the transmission coupling Ⅱ216 to drive the worm gear mechanism Ⅰ217 and the worm gear mechanism Ⅱ, and further drive the worm gear mechanism Ⅲ221 and the worm gear mechanism Ⅳ222 through the coupling Ⅲ219 and the coupling Ⅳ220, thereby realizing the Z-direction displacement control of a set of screw rods and realizing the Z-direction adjustment of the steering wheel.

[0056] The Y-direction adjustment mechanism of the steering wheel is connected to the Y-direction slider 229 of the steering wheel below the slider connection plate 230 through the slide rail, and then the X-direction adjustment mechanism connector 231 is connected to the X-direction adjustment mechanism through bolts. The Y-direction adjustment motor 227 of the steering wheel drives the screw rod to drive the connector IV 228 (connecting the screw rod and the mechanism, thereby realizing the Y-direction adjustment of the steering wheel.

[0059] The multi-degree-of-freedom automobile driver verification device of the present invention includes adjustment mechanisms such as the driver's seat, the driver's floor, the steering wheel, and the chassis frame. By increasing the motion stroke of each mechanism and equipping the electronic control system, the multi-degree-of-freedom remote control of each mechanism of the test bench is realized to meet the rapid switching between different models, and the stroke accuracy is ensured by the dual verification of virtual positioning and three-coordinate positioning. The virtual reality system includes three high-performance computers and three sets of VR equipment. Techviz software and optical motion capture technology are used to accurately fit the transmitted images to the flexible frame, solving the defects of traditional virtual reality technology in motion tracking and image quality, realizing the rapid introduction of vehicle models and accurate positioning of VR images, and can be used for rapid review in the automobile design process.

[0061] like Fig.14 As shown in the figure, the VR review process is as follows: First, the reviewer inputs the hard points of the vehicle platform. The staff adjusts the position of the steering wheel, seat and floor according to the input hard points. Next, use the VR equipment to check whether the position of the bench mechanism is accurate. If it is inaccurate, it is necessary to readjust each mechanism until the position is adjusted in place. After the adjustment is completed, the subjective review of the bench can be carried out. If the reviewer does not have a virtual review requirement, the review ends; if there is a requirement, the staff will start the virtual review system, synchronize the vehicle model data, and assist the reviewers to wear VR equipment for virtual subjective review.
