Description

Technical Field

[0001] This utility model relates to the field of experimental equipment for seat adjusters, specifically an experimental device for automotive seat adjusters. Background Technology

[0002] Among the many core components of a car seat, the seat adjuster plays a crucial role. It directly determines the flexibility, stability, and safety of the seat back angle adjustment, and its performance directly affects the comfort of passengers and driving safety. To ensure that the car seat adjuster can work stably and reliably in actual use, comprehensive and precise performance testing is required in product development, production, and quality inspection.

[0003] Currently, existing automotive seat adjuster testing equipment on the market has many limitations in practical applications. In terms of testing efficiency, most devices can only test a single adjuster at a time. When it is necessary to test the performance of batch products or multiple parameters, repeated operations are often required, which not only consumes a lot of time but also requires a large amount of manpower for monitoring and operation, resulting in high testing costs and making it difficult to meet the needs of efficient production and research and development.

[0004] In terms of equipment structure, some experimental equipment has a complex design with numerous components and cumbersome connection methods. This not only increases the difficulty of the manufacturing process and raises production costs, but also brings inconvenience to the assembly, maintenance, and subsequent repair of the equipment, which is detrimental to the long-term stable operation of the equipment. Regarding experimental accuracy, existing equipment often lacks precision in measuring the force applied to the angle adjuster. Traditional measurement methods mostly employ indirect measurement or contact sensors, which are easily affected by external environmental interference, and the real-time performance and accuracy of the measurement data are insufficient, making it difficult to provide a reliable basis for experimental data analysis, thus affecting the accurate evaluation of the angle adjuster's performance. Utility Model Content

[0005] The purpose of this invention is to provide a test device for an automotive seat adjuster, which aims to solve the problems of cumbersome operation and inaccurate measurement of existing automotive seat adjuster test devices.

Several test plate groups are installed at the head of the multi-head moving frame, and the test plate groups are rotatably connected to the multi-head moving frame.

[0008] Preferably, the top frame includes an outer panel, a connecting inner panel, and a mesh panel. The connecting inner panel is symmetrically installed on both sides of the inner side of the outer panel. The connecting inner panel is integrally formed with the outer panel, and the mesh panel is fixedly installed on the outer side of the connecting inner panel.

[0009] Preferably, the guide rail base includes a slide rail and an outer ear plate, the outer ear plate is fixedly installed on both sides of the slide rail, and the outer ear plate is fixed to the inner side of the base plate by bolts.

[0010] Preferably, the multi-head movable frame includes a sliding frame plate and a vertical plate base for rotating and mounting the experimental plate group. The sliding frame plate is slidably mounted in a slide rail, and the vertical plate base is uniformly and vertically mounted on the sliding frame plate, and the vertical plate base is fixedly connected to the sliding frame plate.

[0011] Preferably, the experimental plate assembly includes an inclined plate, a connecting pipe, and a connecting shaft rotatably connected to the upright plate base. The connecting pipe is fixedly installed at the head of the inclined plate, and the connecting shaft is installed at the lower end of the inclined plate.

[0013] Compared with existing technologies, the beneficial effects of this utility model are as follows: This application, through the design of a multi-head moving frame and multiple experimental plate groups, allows for simultaneous experiments on multiple angle adjusters, greatly improving experimental efficiency and saving experimental time and labor costs. The experimental equipment has a simple structure and is easy to manufacture and assemble. The operating table allows operators to conveniently perform experimental operations and collect data. The application of a ring pressure sensor allows for precise measurement of the force on the angle adjuster during the experiment, providing a reliable basis for experimental data analysis and improving experimental accuracy. The rotatable connection between the experimental plate groups and the multi-head moving frame simulates the angle adjustment process of the angle adjuster, more realistically reflecting the performance of the angle adjuster in actual use. By replacing experimental plate groups of different specifications, experiments can be conducted on different models of angle adjusters, demonstrating strong versatility. Attached Figure Description
