Abstract
Disclosed is a sensor fixing device in sitting posture influence test for passengers of mini-type electric cars. The sensor fixing device comprises an upper fixing plate and a lower fixing plate, when a passenger lays both legs down and sits straightly on a seat, the upper fixing plate is fitted to a breast and a belly of the passenger, the lower fixing plate is fitted to two knees and thighs of the passengers, and three platforms for arranging the sensors are arranged on the outer surfaces of the upper fixing plate and the lower fixing plate respectively. The sensor fixing device is high in repeated accuracy during test and very applicable to a test method for obtaining average values through many tests for eliminating operation error, and accuracy of results in dynamic tests of people and the seat is guaranteed.
Description
Technical field
The present invention relates to for grasp the variation of occupant sitting posture the impact of the riding stability of miniature electric automobile is done experiment time, placement sensor is in occupant's stationary installation with it.
Background technology
Electric automobile (four-wheel electric motor car) has the substantially free of contamination advantage of environment; The miniature electric automobile (only have the seat sat for a people, occupant is also the small-sized electric vehicle of driver simultaneously) that one people takes when going on a journey, not only have the advantage can saving the energy, the area on road occupying width and parking stall is also very little.The relation that exactly because width scales is less and its quality is also very little, occupant's sitting posture variation on the seat just can not ignore the impact of the riding stability of miniature electric automobile.Therefore, people's chair dynamic test (be fixed on by seat on people's chair dynamic test stand, then occupant is sitting in seat and tests) of simulating crew sitting posture variation on the seat, just becomes one of test must done in the development process of miniature electric automobile.Obviously, at the trial, except needing on the seat except placement sensor, with it also should placement sensor occupant, to test people's chair correlativity or to test.Under normal conditions, being placed in the sensor on human body, is all directly be bundled on human body (trunk, four limbs and/or other necessary positions) surface.But, for people's chair dynamic test, occupant's sitting posture variation on the seat, computing machine by being connected with sensor being converted into displacement when occupant's center of gravity (barycenter) changes or relative coordinate variable quantity, being converted into the information such as variation speed, acceleration of occupant's center of gravity, and when sensor is directly bundled on human body surface, because the repeatable accuracy bundling position is too poor, therefore, just excessive error must be brought when computing machine converts.Again because sensor is sensitiveer, the situations such as the heartbeat of occupant, the contraction of muscle and expansion all may make sensor that unnecessary shake occurs, and this also brings the error that can not ignore just to the collection of data.Therefore, if mode conventionally carrys out placement sensor, when people's chair dynamic test of simulating crew sitting posture variation on the seat, its accuracy is just very poor.
Summary of the invention
The object of the invention is, providing a kind of the result of underwriter's chair dynamic test can have sensor fastening device in the miniature electric automobile occupant sitting posture impact test of better accuracy.
The technical scheme realizing described goal of the invention is the sensor fastening device that a kind of like this miniature electric automobile occupant sitting posture affects in test, and this sensor fastening device is made up of a upper mounted plate and a bottom plate; To keep flat and just from the seat, the chest of fixed plate and occupant and belly are fitted at occupant's both legs, two knees and the thigh of bottom plate and occupant are fitted; On the outside surface of upper mounted plate and bottom plate, respectively there is the platform of three placement sensors; In three platforms on upper mounted plate outside surface, a position in the middle of corresponding occupant's chest, another two split in the position of corresponding occupant left and right belly with symmetry status; In three platforms on bottom plate outside surface, two split in the position of corresponding occupant left and right thigh root with symmetry status, a correspondence is arranged between occupant's two knees, and the center of this platform is 10 ~ 20cm to the distance of bottom plate upper surface highest point; On upper mounted plate and a bottom plate, all have the elasticity rope band on the occupant of they bindings.
As can be seen from scheme, the upper bottom plate in the present invention is all fitted with the relevant portion of occupant's human body, so, just can reduce the Acquisition Error of data.Because the present invention is not only provided with the platform of placement sensor specially on the surface of upper bottom plate, and the relative position between every three platforms, limited by upper bottom plate respectively, so, when the data reduction of sensor collection is become the parameter of occupant's center of gravity by computing machine, the problem that the error brought because of the repeatable accuracy of position " binding too poor " is larger would not be there is, also be, the repeatable accuracy of the present invention when doing experiment is higher, be suitably for very much and get rid of operate miss and obtained the test method of mean value by test of many times, the result of underwriter's chair dynamic test can there is better accuracy.
Below in conjunction with accompanying drawing, the present invention is further illustrated.

Embodiment
Miniature electric automobile occupant sitting posture impact test in sensor fastening device, it is characterized in that, this sensor fastening device by a upper mounted plate 1(with reference to figure 1,2) and a bottom plate 2(with reference to figure 3,4) form; To keep flat and just from the seat at occupant's both legs, fixed plate 1 is fitted with belly with the chest of occupant, and two knees and the thigh of bottom plate 2 and occupant fit (with reference to figure 5,6); On the outside surface of upper mounted plate 1 and bottom plate 2, respectively there is the platform 3 of three placement sensors; In three platforms 3 on upper mounted plate 1 outside surface, a position in the middle of corresponding occupant's chest, another two split in the position of corresponding occupant left and right belly with symmetry status; In three platforms 3 on bottom plate 2 outside surface, two split in the position of corresponding occupant left and right thigh root with symmetry status, a correspondence is arranged between occupant's two knees, and the center of this platform is 10 ~ 20cm to the distance h of bottom plate 2 upper surface highest point; On upper mounted plate 1 and a bottom plate, all have the elasticity rope band (due to obvious, omitting elasticity rope band in accompanying drawing) on the occupant of they bindings.
It will be apparent to those skilled in that, the upper mounted plate 1 in the present invention and bottom plate 2, its material selection engineering plastics are better, and, both can adopt traditional injection moulding processing mode, also can adopt up-to-date 3D printing technique manufacture.
Those skilled in the art is clear equally, and sensor both can be pasted on the platform of upper mounted plate 1 and bottom plate 2 by bonding mode, also sensor can be fixed by screws on described platform.
