Detailed Description
In the present invention, the embodiments and the features of the embodiments may be combined with each other without conflict.
The present invention will be described in detail with reference to the accompanying drawings in conjunction with embodiments.
In connection with fig. 1, according to an aspect of the present invention, there is provided an H-point bar, including:
the telescopic rod comprises a rod body 1, wherein the rod body 1 comprises a main rod 5 and a telescopic rod 6 which can stretch relative to the main rod 5;
the transmitting unit 2 is arranged on the telescopic rod 6, the transmitting unit 2 is arranged to be capable of rotating relative to the main rod 5, and the transmitting unit 2 comprises an X-direction transmitter 4 capable of transmitting light beams perpendicular to the length direction of the rod body 1.
And during the use process of the H-point rod, tools such as an auxiliary tape measure and the like are needed to measure the X, Y and Z three-way distances of the component to be measured relative to the H point. The utility model discloses a H point pole can stretch out and draw back as required to make X to the transmitter with the corresponding position of part to be measured (this position and the Y of the distance between the H point for the part to be measured are to the distance for H point), rotate afterwards and adjust the transmitting element in order to launch horizontal light beam and vertical light beam with the corresponding position of part to be measured, at this in-process, utilize the tape measure (not limited to the tape measure, also can be for other measuring tool) to measure the part to be measured for other two-way distances of H point along horizontal light beam and vertical light beam trend respectively, make among the actual measurement process, can directly measure man-machine data as required, high measuring efficiency, and reduce measuring error, improve the reference value of data.
Specifically, the distance between the part to be measured and the H point can be measured by using the H point rod in the following two ways:
firstly, an X-direction emitter 4 is opened, the X-direction emitter 4 emits a light beam perpendicular to the length direction of a rod body 1, the extension length of a telescopic rod 6 relative to a main rod 5 is adjusted, and the emitting unit 2 is rotated along 360 degrees so as to change the position of the emitting unit 2 and the emitting direction of the light beam, at the moment, the light beam can be inclined, horizontal or vertical until the light beam emitted by the X-direction emitter 4 of the emitting unit 2 can just hit a component to be measured, and at the moment, the distance from a point H to the X-direction emitter 4 is the Y-direction distance of the component to be measured relative to the point H;
then, a measuring tape (not limited to a measuring tape, but also other reference tools such as a rope) is used for extending the position of the component to be measured in the horizontal X direction by means of a tool such as a level meter or a plumb, on the basis of ensuring that the length of the X-direction emitter 4 in the direction corresponding to the H point and the Y direction is not changed, the emitting unit 2 is adjusted to the first angle position in a rotating mode, so that the X-direction emitter 4 emits a vertical light beam capable of intersecting with the extended measuring tape (the vertical light beam can be upward or downward, and the light beam can be intersected with the extended measuring tape), another measuring tape (not limited to the measuring tape, but also other measuring tools) is placed along the trend of the light beam, and the distance from the intersection point to the X-direction emitter 4 is measured along the trend of the;
and then, a measuring tape (reference tool) is used for extending the position of the component to be measured in the vertical Z direction by means of a plumb tool and other tools, on the basis of ensuring that the length of the X-direction emitter 4 in the direction corresponding to the H point Y is not changed, the emitting unit 2 is rotated and adjusted to a second angle position, so that the X-direction emitter 4 emits a horizontal light beam capable of intersecting with the extended measuring tape (the horizontal light beam can be forward or backward in the direction shown in the figure, and the light beam can intersect with the extended measuring tape), the vertical light beams of the horizontal light beam are perpendicular to each other, the measuring tape is placed along the direction of the light beam, and the distance from the intersection point to the X-direction emitter 4 is measured along the direction of the horizontal light beam, namely.
Secondly, the position of the component to be measured is extended in the horizontal Y direction by a level gauge directly by using a tape measure, and meanwhile, the extension length of the telescopic rod 6 relative to the main rod 5 is adjusted, and the transmitting unit 2 is rotated to enable the X to emit a vertical light beam to the transmitter 4 until the vertical light beam can intersect with the extended tape measure;
after the telescopic rod 6 is adjusted, the distance from the X-direction emitter 4 to a point H along the length direction of the rod body 1 is the Y-direction distance of the component to be measured relative to the point H, and the distance from the intersection point to the X-direction emitter 4 along the direction of the vertical light beam is the Z-direction distance of the component to be measured relative to the point H;
and then, extending the position of the component to be measured in the vertical Z direction by using a measuring tape with the aid of tools such as a plumb and the like, adjusting the extending length of the telescopic rod 6 relative to the main rod 5, rotating the transmitting unit 2 to emit a horizontal light beam to the X-direction transmitter 4 until the horizontal light beam can be intersected with the extended measuring tape, and measuring the distance from an intersection point to the X-direction transmitter 4 along the direction of the horizontal light beam by taking another measuring tape, namely the X-direction distance of the component to be measured relative to the H point.
It will be appreciated that, for measurement, the reference tool, such as the tape measure, is required to extend horizontally and vertically towards the H-point bar, and the X-direction emitter 4 is required to emit a light beam towards the position of the component to be measured, so as to ensure that the two beams intersect, and are adjusted accordingly according to the measurement requirements.
It should be noted that the measuring sequence of the X, Y and Z three-way distance need not strictly follow the above sequence, and can be adjusted at will during actual measurement, which is not limited by the present invention.
The first is that the telescopic rod 6 can rotate relative to the main rod 5, the second is that the telescopic rod 6 cannot rotate relative to the main rod 5, and the transmitting unit 2 can rotate relative to the telescopic rod 6, and the transmitting unit 2 can also rotate relative to the main rod 5, and the two modes can be arbitrarily selected in practical use.
In order to facilitate the rotation of the firing unit 2, the firing unit 2 is rotatably mounted on the telescopic rod 6. The telescopic rod 6 can only extend and retract relative to the main rod, and does not rotate relatively.
Because the in-process of auxiliary measurement, for guaranteeing measured data's accuracy, need make X launches the light beam of horizontal direction or vertical direction to emitter 4, if it is comparatively loaded down with trivial details to utilize spirit level or protractor to carry out the calibration operation process to the light beam direction of transmission at every turn, based on the above-mentioned problem, telescopic link 6 is equipped with four indication scale 3 along the even interval of circumference, be equipped with on emission unit 2 with X corresponds to emitter 4 in order emission unit 2 rotate the in-process can with on the body of rod 1 one among the indication scale mark scale is relative.
After the H-point rod is installed, the orientation positions of the four indication scales 3 are calibrated by using a level, a plumb or an angle gauge, so that after the marked scales of the emitting unit 2 are aligned with the four indication scales 3, the X-direction emitter 4 can emit light beams which are horizontally forward, horizontally backward, vertically upward and vertically downward respectively. Through setting up above-mentioned scale, the calibration once can before the use of H point pole, need not the calibration before the use at every turn, makes things convenient for follow-up data measurement to use.
According to the above, the first angular position of the emitting unit 2 means that after the marked scale is aligned with one of the indicating scales, the X-direction emitter 4 can emit a light beam in a vertical direction, the X-direction emitter 4 rotates to be located above the emitting unit 2, that is, emits a light beam in a vertical upward direction, and the X-direction emitter 4 rotates to be located below the emitting unit 2, that is, emits a light beam in a vertical downward direction; the second angular position of the emitting unit 2 means that the X-direction emitter 4 can emit a horizontal light beam after the marked scale is aligned with one of the indicating scales, and the specific horizontal forward or backward direction is determined by the orientation of the X-direction emitter 4.
Further, the X-direction emitter 4 is correspondingly arranged on an extension line of a marking scale on the emitting unit 2 extending along the length direction of the rod body 1, so that when the marking scale is aligned with the indication scale of the horizontal position, the X-direction emitter 4 can emit a horizontal light beam.
It can be understood that the connection mode between the main rod 5 and the telescopic rod 6 can be selected arbitrarily, as long as the telescopic action of the rod body 1 can be ensured. In this embodiment, the main rod 5 is sleeved on the telescopic rod 6, and the launching unit 2 is disposed at an end of the telescopic rod 6, so as to facilitate rotation adjustment of the launching unit 2.
It should be noted that, after the telescopic rod 6 is telescopically adjusted, it is inconvenient to measure the distance from the point H to the X-direction emitter 4 on the telescopic rod 6, so that it is considered that scales on the telescopic rod 6 are separately measured, and in this embodiment, a first scale is provided on the telescopic rod 6 along the length direction to calculate the extending distance of the telescopic rod 6 relative to the main rod 5. Therefore, the length of the main rod 5 is known and fixed, the center point of the main rod 5 is usually the point H, and the length from the emitter 4 to the main rod 5 on the telescopic rod 6 can be superposed by the known length to acquire the data in the X direction to be measured.
In addition, the telescopic rod 6 is under the flexible condition, in order to guarantee the measurement demand, the X must be exposed outside the mobile jib 5 to the transmitter 4 all the time, therefore the zero scale mark of the first scale on the telescopic rod 6 sets up the X on the emission unit 2 to the position of transmitter 4.
Of course, the emitting unit 2 can be set to any shape on the basis of rotating relative to the main rod 5, and in order to ensure the measurement accuracy, the emitting unit 2 is preferably set to a regular shape, specifically, the emitting unit 2 is a cylindrical structure with an axis extending direction consistent with the length direction of the telescopic rod, and the X-direction emitter 4 is arranged on the circumferential wall surface of the emitting unit 2. Preferably, the telescopic rod 6 is also provided as a cylindrical structure.
In order to realize the width measurement of some parts to be measured beyond the measurement range of the H-point rod, the emitting unit 2 further comprises a Y-direction emitter 7 for emitting a light beam extending along the length direction of the rod body, and further, the Y-direction emitter 7 is arranged on the end face of the emitting unit 2. Therefore, the distance between the part and the point H along the length direction of the rod body can be measured in an auxiliary mode. The Y-direction emitter 7 and the X-direction emitter 4 are common laser emitters, and power is supplied by a power supply in the using process.
In order to measure multidirectional man-machine data in the vehicle, the two sides of the main rod 5 are respectively provided with the telescopic rods 6. Each telescopic rod 6 is arranged by adopting the structure, so that the three-way distance of the omnibearing part to be measured relative to the point H is measured.
The utility model discloses the second aspect still provides a dummy measuring device, include:
a dummy comprising a torso portion and a thigh portion;
the H-point rod is the H-point rod in any scheme, and the H-point rod is arranged to penetrate through the dummy along the hinge line of the trunk and the thigh.
It should be noted that after the H-point rod is installed, the four indicating scales 3 can be calibrated by using a level, plumb or protractor, so as to ensure that the X-ray emitter 4 can emit horizontal or vertical light beams without using any auxiliary tool. For the convenience, can utilize the plumb to calibrate the instruction scale of vertical direction, because four instruct the scale to be followed the circumference of telescopic link 6 evenly sets up, when two of them instruct the scale and set up along vertical direction, all the other two instruct the scale and must set up along the horizontal direction.
When the dummy is placed, the backrest of the vehicle can be adjusted to a common driving angle, and then subsequent measurement is carried out.
In order to increase the convenience of the measuring process and reduce the utilization of auxiliary tools, the H point rod is provided with a second scale along the length direction, the zero scale mark of the second scale is arranged at the middle position of the H point rod, particularly, the middle position of the H point rod is also the middle point of the main rod 5, the zero scale mark of the middle point extends to two sides respectively to mark scales, the distance from the middle point to the end part of the main rod 5 is added with the distance from the X-direction emitter 4 to the end part of the main rod 5 on the telescopic rod 6, namely, the distance from the part to be measured to the end part of the main rod 5 relative to the X-direction of the H point, therefore, after the telescopic rod 6 is adjusted to a proper position, the measuring data can be directly obtained through the scales on the main rod.
Adopt the utility model discloses a dummy measuring device can conveniently obtain the man-machine data of car inner part for the H point.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
