In the present disclosure, the use of directional words such as "upper, lower, front, and rear" in the case where no description is made to the contrary, generally means that they are defined in the case where the front seat provided in the present disclosure is normally used. When the following description refers to the accompanying drawings, like numbers in the drawings represent the same or similar elements unless otherwise indicated.
The present disclosure provides a method for checking a front seat arrangement, with particular reference to fig. 1 and 2, the method for checking a front seat arrangement includes the following steps: in step S1, obtaining a theoretical travel track 2 of the seat, inputting the theoretical travel track 2 into a digital prototype, specifically, arranging a sensor on the seat, detecting the displacement of the seat by the sensor, further outlining the displacement of the seat, quantizing the shape of the outline into a function according to parameters, inputting the function into the digital prototype, and generating the theoretical travel track 2 of the seat by the digital prototype; in step S2, a reference point 1 of the seat is selected, the position information of the reference point 1 is input into the digital prototype and is associated with the theoretical stroke track 2, wherein the reference point is any point fixed relative to the seat, and the stroke track of the seat is reflected by the motion track of the reference point after the association is established; at step S3, data of the object part is input into the digital prototype and associated with reference point 1, and the object part moves along with reference point 1, which is equivalent to moving along with the seat, in the coordinate space formed by reference point 1. It should be noted that parameters of each component exist during the production of the seat, and the parameters are directly input into the digital prototype to obtain the theoretical stroke track 2 of the seat and the data of the object component; in step S4, the motion of the object part is simulated in the digital sample machine, and at this time, whether the object part has motion interference can be visually 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 spatial checking of the front seat. The interference data can be directly embodied in a picture form or through a function, for example, interference exists when a certain numerical value exceeds a standard value; in step S6, the actual mounting position of the target component is determined based on the interference data. Specifically, if the object part interferes with the peripheral parts, the position of the object part is adjusted, the adjusted data of the object part is input into the digital prototype, the steps S3-S5 are repeated, and the space check of the front row seat is carried out again; if the subject component does not interfere with the peripheral component, the arrangement check of the front seat is completed.
It should be noted that the sequence of steps S1 and S2 is not limited, for example, the position information of the reference point 1 may be input into the digital prototype first, and then the theoretical seat stroke track 2 may be input into the digital prototype, and the position information of the reference point 1 and the theoretical seat stroke track 2 may be input into the digital prototype and associated with each other, which all belong to the protection scope of the present disclosure.
According to the technical scheme, a point-curve kinematic pair is set on a reference point 1 and a theoretical seat stroke track 2 through a digital prototype technology, data of an object part are input into the digital prototype, the effect of the object part during seat movement can be observed under the operation of the digital prototype technology, the spatial relationship between the seat and accessories thereof and peripheral parts can be checked effectively, intuitively and comprehensively according to a total arrangement scheme and the motion relationship of the seat, and meanwhile, a motion envelope of the seat and accessories thereof can be generated to be used as a reference for subsequent total arrangement design and check.
Further, referring to fig. 2, the reference point 1 is selected as the center point of the axis connecting the thigh and the trunk of the human body when the seat is at any one of the extreme positions, which are the positions when the seat is respectively at the front upper position, the front lower position, the rear upper position and the rear lower position. Specifically, the reference point is an R point, which is a design reference point specified by a seat manufacturer, and the R point is generally set to the rearmost, lowermost position of the seat in normal driving or seating, in consideration of all adjustment forms of the seat.
In step S5, the motion interference check is performed on the target component in conjunction with the cross-sectional analysis.

The spatial relationship between the front seat and peripheral components in the motion process can be well checked through a digital prototype technology, and a motion enveloping body can be generated. On the basis of section analysis, the method is combined with a general arrangement checking method of a digital prototype technology, the effect is more visual and understandable, and the effect of general arrangement design and checking work is obvious.
According to some embodiments, the object components include, but are not limited to, a seat harness interface, an under seat attachment, and a seat belt buckle. When the arrangement is checked, the data of one object part is input into a digital prototype to carry out interference check.
In addition, the data of the object component comprises the shape, the installation position, the installation angle and the like of the object component, the shape, the installation position and the installation angle of the object component are input into the digital prototype and are related to the reference point 1, the motion of the object component is simulated in the digital prototype, the motion enveloping body of the object component can be generated, and then the motion interference data of the object component is obtained and is used as the reference for the subsequent total layout design and check. Furthermore, the seat comprises a plurality of accessories, if the arrangement scheme is changed, the data of the new object part can be input into the digital prototype to run, and then the comprehensive space checking and checking can be carried out on the seat accessories, so that the checking efficiency is improved.
Further, the peripheral components include, but are not limited to, floor center, under-seat carpet, rear air outlets, and wiring harnesses. The method for checking the arrangement of the front row of seats can be applied to checking the space between accessories below the seats and a carpet and a rear air outlet, and can also be applied to checking the space between components such as a seat cushion, a safety belt lock catch and the like and a floor central control. Through the technical scheme, the safety clearance between the object component and the peripheral component can be ensured, and the design problems of interference, abnormal sound and the like are avoided.
