Auxiliary measuring device for automobile h-point and method for marking design position of automobile h-point

Abstract

The invention relates to a device for automobile H point auxiliary measurement. The device comprises a positioning member and a first pointer. The positioning member comprises a body and at least a supporting portion which is disposed on the body and is matched with a saucer shape on an automobile auxiliary dashboard so that the supporting portion can be inserted into the saucer. The first pointer is disposed detachably on a side of the body, and through a position of a pointer head, the first pointer can mark the design position of an X coordinate and a Z coordinate of the H point of an automobile front row seat in a reference space rectangular coordinate system, a design reference point on the automobile being an origin of the coordinate system, and a direction of longitudinal automobile body, horizontal automobile body and a direction that is perpendicular to a direction of a automobile bottom height are respectively the directions of an X axis, a Y axis, and a Z axis. The invention also relates to a method for marking the design position of the automobile H point. The device and the method are advantaged by reasonable design, accurate positioning, flexible disassembly and assembly, convenient use, etc. With the device and the method, the H point design positions of the front row and a rear row of the automobile can be easily, rapidly and accurately marked, and the device and the method can effectively overcome shortcomings in respect of determining the automobile H point design position in prior art.

Description

【Technical field】 [0001] The invention belongs to the technical field of automobile indoor measurement, and in particular relates to an auxiliary measuring device for an automobile H point and a method for marking the design position of the automobile H point by using the device. 【Background technique】 [0002] In the early stage of vehicle development, in order to verify the design effect of the overall layout space inside the vehicle, many vehicle verification models need to be produced. When the simulated human body is placed on the vehicle verification model for measurement, the H point of the seat needs to be adjusted, and the design position of the H point needs to be marked during the adjustment. Therefore, from the perspective of convenient measurement, it is very necessary to design and provide a device that can quickly and accurately mark the design position of the H point. [0003] Yet the device that is used for the auxiliary measuring device of H point of the a...

Problems solved by technology

[0003] Yet the device that is used for the auxiliary measuring device of H point of the automobile that provides in the prior art also has many defects such as bulky, not easy to disassemble etc., for example in national standard " automobile H point determination program " (GB / The three-dimensional H-point device disclosed in T11563-1995) is composed of many parts such as a back plate, a seat plate, a spirit level and a protractor, which is not conducive to the measurement operation

In addition, since the H-point auxiliary measuring device is usually set on the threshold for positioning, this will cause the above auxiliary measuring device to be unstable in positioning due to the error of the body parts itself, thus affecting the measurement data. Reliability, so that there is actually a large error between it and the actual design position of point H
