[0029] The following description provides many different embodiments or examples for implementing different features of the present invention. The components and arrangements described in the following specific examples are only used to simplify the present invention and are only used as examples, not to limit the present invention.

[0030] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] The measurement of the car's posture includes the car's height, tire height, tire wheel arch gap, etc. The existing measuring tools all need to contact the car to obtain the measuring points, or use the human eye to judge the measuring points. The measuring points obtained in the above manners have certain errors, resulting in poor accuracy of the final measurement. The utility model improves the accuracy of the measurement by obtaining accurate measuring points.

[0032] This embodiment provides a passenger car measurement tool, such as Figure 1As shown, it includes a horizontal workbench 10, a slide rail 20, a slider 30, a laser module 40 and a measuring structure. The horizontal workbench 10 is connected to the slide rail 20, the slider 30 is arranged on the slide rail 20, the laser module 40 is arranged on the slider 30, the laser module 40 emits a laser that acts on the vehicle to obtain a measuring point, and the measuring structure is arranged on the slide rail 20 and / or the slider 30, and is used to measure the measurement value of the measuring point.

[0033] It should be noted that the slide rail 20 and the slider 30 to be calibrated can be existing products, and the specific structure will not be described in detail here.

[0034] It should be noted that the slide rail 20 and the slider 30 to be calibrated can be existing products, that is, existing matching slide rail 20 and slider 30 products; the slide rail 20 can be obtained by setting scales on the slide rail 20.

[0035] Furthermore, in some embodiments, at least two sliders 30 are provided. At least two sliders 30 can realize simultaneous measurement of at least two measurement points, unify the measurement reference, achieve zero error between the values ​​of the measurement points, and improve the measurement accuracy.

[0036] Further, in some embodiments, the measuring structure includes a scale and / or a measuring sensor; the scale is disposed on the slide rail 20 , and / or the measuring sensor is disposed on the slider 30 .

[0037] When the structure of the utility model measures the measurement value of a measurement point, the measurement can be performed by means of a scale, the measurement can also be performed by means of a measurement sensor, or the measurement can be performed by means of a scale and a measurement sensor together; by measuring in two ways together and verifying each other, the measurement accuracy can be improved.

[0038] It should be noted that when reading the scale through the position of the slider 30, it is necessary to read according to a unified standard, such as reading the scale of the upper end of the slider 30 on the slide rail 20, or reading the scale of the lower end of the slider 30 on the slide rail 20.

[0039] By means of a scale, when measuring, the slider 30 is slid so that the laser emitted by the laser module 40 hits the point to be measured, and then the scale at the position of the slider 30 is read; if there is only one slider 30, if the distance between two measuring points (such as the tire wheel arch gap) is to be measured, it is necessary to measure twice to obtain two scales, and then subtract the two scales to obtain the distance between the two measuring points; if there are more than two sliders 30, if the distance between two measuring points is to be measured, the measurement can be completed once to obtain two scales, and then the two scales are subtracted to obtain the distance between the two measuring points.

[0040] The method of measuring by the measuring sensor is the same as that of the scale, and will not be described in detail here.

[0041] Further, in some embodiments, the measuring sensor includes a position sensor or a capacitive sensor.

[0042] Furthermore, in some embodiments, a terminal 70 is also included, and the terminal 70 includes a data processing module, and the data processing module is used to receive the height value measured by the measurement sensor and process the measurement value to obtain a target value; it should be noted that the target value is the distance between the two measurement points to be measured, or the height between the two measurement points; the measurement value is the height of a measurement point; but there is also a situation where the measurement value is equal to the target value (that is, when the measurement value of the measurement point located below is 0). Based on this, automatic measurement can be achieved without manual reading; at the same time, the value of manual reading and automatic measurement can be compared and verified to further improve the accuracy of the measurement.

[0043] Furthermore, in some embodiments, the terminal 70 further includes a display screen, and the display screen is used to display the measurement value and / or the target value, so as to facilitate obtaining the measurement result and improve the efficiency of the measurement.

[0044] Furthermore, in some embodiments, a horizontal correction plate 50 is further included, and the horizontal correction plate 50 is used to cooperate with the measurement position of the vehicle. Figure 2 As shown) or when measuring the wheel arch clearance of the tire, the horizontal correction plate 50 can cooperate with the tire to obtain more accurate measurement points, thereby improving the measurement accuracy.

[0045] Furthermore, in some embodiments, the horizontal correction plate 50 is provided with a universal level bubble 60 to ensure that the horizontal correction plate 50 is in a horizontal state, thereby improving the accuracy of obtaining the measurement points.

[0046] Furthermore, in some embodiments, the terminal 70 includes a data processing module, and the data processing module is used to calculate the scale to obtain the measured length. Through this, the measured scale can be mathematically calculated to obtain the measured length, which has the advantage of improving measurement efficiency.

[0047] It should be noted that the measured length refers to all the heights that need to be measured, such as vehicle height, wheel arch tire clearance height, tire height, height from wheel center to tire edge, etc.

[0048] Furthermore, in some embodiments, a universal level bubble 60 is provided on the horizontal workbench 10. If the passenger car is not on a horizontal ground during measurement, the car posture needs to be measured. When the device of the utility model is used for measurement, it is necessary to ensure that the device of the utility model is in a horizontal state. The universal level bubble 60 cooperates to ensure that the device of the utility model is in a horizontal state for measurement, thereby improving the accuracy of the measurement.

[0049] This embodiment also provides a high-precision passenger car measurement method, including the above-mentioned measurement device, and the measurement method includes the following steps:

[0050] The slider 30 is moved so that the laser emitted by the laser module 40 on the slider 30 hits the measuring point of the passenger car.

[0051] Obtain the scale corresponding to the position of the slider 30 on the slide rail 20; because the measurement is carried out by a ruler, the ruler is set on the slide rail 20, and the slider 30 slides, so that the laser emitted by the laser module 40 hits the vehicle to obtain the measurement point. At this time, the scale corresponding to the position of the slider 30 on the slide rail 20 is the measurement value of the measurement point.

[0052] The measured length is obtained via the scale.

[0053] like Figure 2 As shown, when measuring the tire fender gap height, move the two sliders 30 to obtain the measurement points on the tire and the fender respectively. After obtaining the accurate measurement points, read the scale on the slide rail 20 to obtain the heights of the two measurement points, and then calculate the target value through the heights of the two measurement points.
