In the present disclosure, unless otherwise indicated, the use of directional terms such as "upper, lower, front, rear" generally refer to those defined in the context of normal use of the front seat provided by the present disclosure. When the following description refers to the accompanying drawings, like numerals refer to the same or similar elements throughout the drawings unless otherwise indicated.
The present disclosure provides a front seat arrangement checking method, specifically referring to fig. 1 and 2, including the steps of: in step S1, a theoretical travel track 2 of the seat is obtained, and the theoretical travel track 2 is input into a digital prototype, specifically, a sensor may be arranged on the seat, the displacement of the seat is detected by the sensor, the contour of the displacement of the seat is outlined, the contour shape is quantized into a function according to parameters, the function is input into the digital prototype, and the digital prototype can generate the theoretical travel track 2 of the seat; step S2, selecting a reference point 1 of the seat, inputting position information of the reference point 1 into a digital prototype and associating the position information with a theoretical travel track 2, wherein the reference point is any point relatively fixed with the seat, and reflecting the travel track of the seat by a motion track of the reference point after associating the reference point; in step S3, the data of the object part is input to the digital prototype and associated with the reference point 1, and the object part moves with the reference point 1 in the coordinate space formed by the reference point 1, which corresponds to moving with the seat. It should be noted that parameters of each component exist during the production of the seat, and the data of the theoretical travel track 2 of the seat and the target component can be obtained by directly inputting the parameters into a digital prototype; in step S4, the motion of the object part is simulated in the digital prototype, and whether the motion interference of the object part occurs can be intuitively observed and judged; in step S5, a motion envelope of the object component is generated in the digital prototype to obtain interference data of the motion envelope and the peripheral component, so as to implement space check of the front seat. The interference data can be directly represented in a picture form or can be represented by a function, for example, if a certain numerical value exceeds a standard value, interference exists; in step S6, the actual mounting position of the object component is determined from the interference data. Specifically, if the target component interferes with the peripheral component, the position of the target component is adjusted, the adjusted data of the target component is input into a digital prototype, the steps S3 to S5 are repeated, and the space check of the front seat is performed again; if the target component and the peripheral component do not interfere, the arrangement check of the front seats is completed.
It should be noted that, the steps S1 and S2 are not limited in order, for example, the position information of the reference point 1 may be input into the digital prototype, then the seat theoretical stroke track 2 may be input into the digital prototype, and the position information of the reference point 1 and the seat theoretical stroke track 2 may be input into the digital prototype and be associated, which all belong to the protection scope of the present disclosure.
According to the technical scheme, the point-curve kinematic pair is set for the reference point 1 and the seat theoretical stroke track 2 through the digital prototype technology, then the data of the object component is input into the digital prototype, the effect of the object component during the movement of the seat can be observed under the operation of the digital prototype technology, the spatial relationship between the seat and the accessories and the peripheral component can be effectively, intuitively and comprehensively checked according to the total arrangement scheme and the movement relationship of the seat, and meanwhile, the movement envelope of the seat and the accessories can be generated for the subsequent total arrangement design and check as a reference.
Further, referring to fig. 2, the reference point 1 is selected as a center point of a shaft connecting the thighs of the human body with the trunk when the seat is at any one of the extreme positions, i.e., the positions when the seat is respectively at the front upper, front lower, rear upper, rear lower positions. Specifically, the reference point is an R point, which is a design reference point specified by a seat manufacturer, and is generally set at the rearmost, lowermost position of the seat in normal driving or riding, taking into consideration all adjustment forms of the seat.
In step S5, a motion interference check is performed on the target member in combination with the cross-section analysis. When the front-row seat total arrangement design and check are carried out, the section analysis and the digital prototype technology are adopted to carry out all-round check, so that the subsequent arrangement design problem is avoided. The spatial relationship between the front seat and peripheral components in the movement process can be well checked through a digital prototype technology, and a movement envelope body can be generated.

Further, the seat comprises a plurality of accessories, if the arrangement scheme is changed, the data of the new object component can be input into the digital prototype to run, so that the seat accessories can be subjected to comprehensive space check, and the check efficiency is improved.
