Vehicle door inner handrail and its boundary construction method

Abstract

The invention provides an inner armrest of a vehicle door and a boundary construction method thereof. The method comprises the following steps: S1, obtaining the size information of a human body structure; S2, calibrating the innermost position of the second trim plate in the vehicle width direction and the minimum distance from a table top to the human body seat R point along the vehicle length direction; 3, determining that distance from the outer side to the maximum three-coordinate direction of the R point of the human body seat in the rotate state of the elbow of the human body, 4, determining that distance between the lower side of the human body to the maximum three-coordinate direction of the human body seat R point in the rotating state of the elbow of the human body, and calibrating the maximum position of the table top in the vehicle height direction by the distance H1 along the vehicle height direction; 5, calibrating the position of the mesa in the height direction of thevehicle base on that H1 and the minimum distance D1 between the table top and the R point of the human body seat in the length direction of the vehicle-; S6, constructing the armrest inside the vehicle door. The method can effectively reduce the workload of reciprocating checking when the door armrest is structured, and improve the accuracy of the door armrest design.

Description

technical field [0001] The invention relates to the technical field of automobile component manufacturing, in particular to a method for constructing the boundary of a vehicle door inner armrest; at the same time, the invention also relates to a vehicle door inner armrest obtained by the construction method. Background technique [0002] In order to meet the needs of the occupants, the existing vehicle door armrests are mostly designed in a stepped shape. , and the second decorative plate extending from the table to the bottom of the vehicle, the position of the first decorative plate in the width direction of the vehicle should at least meet the non-interference rotation of the elbow of the human body in the car, and the table top should at least meet the requirement for the elbow of the human body support. In the past, the size of the door armrest (elbow rest) was output by each manufacturer. For example, the required distance between the front door armrest and the R poin...

AI Technical Summary

Problems solved by technology

In the past, the size of the door armrest (elbow rest) was output by each manufacturer. For example, the required distance between the front door armrest and the R point of the human seat is 280-315mm in the Y direction (that is, along the vehicle width direction), and the Z direction ( That is, the height along the vehicle height direction) is 190-205mm, and the input shape range will appear to be inconsistent with the design many times, so repeated checks are repeated. When encountering results that are not in the range, I don’t know how to control it, so I have to do it against the standard. The operation is cumbersome. low efficiency
