Description
Technical Field
The invention belongs to the field of automobile seat detection devices, and particularly relates to an automobile seat position state confirmation device and a use method thereof.
Background
With the rapid development of the automobile industry, as one of the key parts of automobiles, automobile seats are required to be arranged reasonably and to ensure riding comfort, and the safety performance of the automobile seats is required to be improved continuously. Therefore, the car seat needs to be tested whether it meets the corresponding performance requirements through various tests (such as dynamic forward and backward impact tests, skeleton static stiffness tests, belt fastening point strength tests, etc.), for example, some extremely important test states are that the seat is located at the design position, the middle position and the final lowest position. For the automobile seat with adjustable front and back, backrest and height, different seat test positions have correspondingly specified backrest angles, slide rail positions and height adjusting positions according to national regulations and industrial standards.
The high-adjusting position of the automobile seat is easy to guarantee except for the uppermost position and the lowermost position, the determination of other high-adjusting positions is generally based on the theoretical relative height provided by a designer, and a tester can guarantee that the automobile seat is located at the high-adjusting position specified in the test by adjusting the height adjusting device of the seat to enable the measured actual relative height to be the same as (or within the allowable error range of) the theoretical relative height. The common relative height is the vertical height of the rotation center of the angle adjuster relative to the upper plane of the lower slide rail on the same side, and currently, the angle adjuster is mainly measured by adopting the following two methods: firstly, two straight steel rulers are used for measurement, one straight steel ruler is used for calibrating the center line of the synchronous rod of the angle adjuster, and the other straight steel ruler is used for keeping the vertical distance between the center line of the synchronous rod of the angle adjuster and the upper plane of the lower slide rail on the same side to be measured vertically; secondly, the measurement is carried out by a three-coordinate measuring instrument, although the accuracy of the measurement result is high, the equipment cost is high, the consumed time is relatively long, and the practicability is not strong.
The angular state of the car seat refers to the angle that the recliner drives the seat back to rotate within a certain stroke for the seat with the adjustable backrest, and under different test states of the seat, the following two methods are mainly adopted for measurement at present: firstly, the angle state of the seat is indirectly determined by selecting a reference angle which is relatively easy to obtain, for example, for a detachable headrest form, the angle of a headrest framework and a plumb line is measured by using an angle meter as a reference, or for a stepped angle adjuster, a tester can take the final state of a seat backrest as a reference and manually adjust the number of stages of the angle adjuster to determine the angle state of the seat, but the measuring method has low accuracy, low efficiency and no universality; secondly, a certain point on the backrest framework of the seat is taken as a reference, for example, the center point of a headrest guide pipe, and the measurement is carried out through a three-coordinate measuring instrument, so that although the accuracy of the measurement result is high, the equipment cost is high, the consumed time is relatively long, and the practicability is not strong.
The front and back position state of the automobile seat is mainly determined by the relative position of the upper slide rail and the lower slide rail in the front and back direction, and the measurement is carried out by a three-coordinate measuring instrument, although the accuracy of the measurement result is high, the defects of high equipment cost, relatively long time consumption and poor practicability exist.
Further, a seating reference point of the seat, also referred to as an R point, is a connection point of a trunk and thighs of the dummy when the 95 th percentile dummy is seated on the seat. In national regulations and industrial standards relating to automobile seats, a considerable number of test items require measurement with reference to a seating reference point of a seat, such as headrest dimension measurement in a headrest performance test, but since the seating reference point is usually located in a suspended position above and behind a seat cushion, it is difficult to obtain an R point, resulting in low measurement efficiency and measurement accuracy. At present, an SAE dummy is mainly used, a plurality of steel rulers are combined on the dummy for manual measurement, the measurement precision is not high, time consumption is long in the preparation stage of the dummy, at least two persons are needed for assistance, the efficiency of measuring a plurality of seats is low, and the personnel cost is wasted.
