[0024] In the related art, the common push-pull force meter on the market is large in size and cannot measure the clamping force when the opening of the vehicle window is small, and there is a lack of special clamping force test tool on the market, so that the operator usually needs to hold the force meter to measure. Because the vehicle window glass is easy to deviate during rising, the test stability is poor, and the repeatability of the measurement result is difficult to guarantee. In view of the above problems, the present application provides a kind of automobile glass clamping force measuring device and detection method, can ensure the accuracy and consistency of measurement result.

[0025] The technical solutions of the embodiments of the present application are described in detail below with reference to the drawings.

[0026] Referring to Figure 1 The automobile glass clamping force measuring device includes a main body 1, a clamping mechanism 2 and a pressure detection mechanism 3. The clamping mechanism 2 includes a clamping plate 21 and an adjusting piece 22. The adjusting piece 22 is connected with the main body 1 and the clamping plate 21 respectively, the adjusting piece 22 is integrally formed with the clamping plate 21, and the adjusting piece 22 and the clamping plate 21 are made of metal or plastic.

[0027] Referring to Figure 1, the clamping plate 21 is arranged opposite to the main body 1, one side of the clamping plate 21 facing the main body 1 is a plane, and one side of the main body 1 facing the clamping plate 21 is a plane. The adjusting piece 22 is used for adjusting the distance between the clamping plate 21 and the main body 1, and the adjusting piece 22 can control the clamping plate 21 to move towards or away from the main body 1, so that the clamping plate 21 and the main body 1 clamp or release the vehicle window glass. The pressure detection mechanism 3 comprises a pressure detection head 31, the pressure detection mechanism 3 is partially arranged in the main body 1, and the pressure detection head 31 is arranged on one side of the main body 1. The side of the main body 1 on which the pressure detection head 31 is arranged is perpendicular to the direction of the clamping plate 21, and the pressure detection mechanism 3 is used for detecting the pressure acting on the pressure detection head 31.

[0028] Referring to Figure 1 In actual use, the worker can place the main body 1 on the edge of the vehicle window glass, make the edge of the vehicle window glass extend into the gap between the main body 1 and the clamping plate 21, adjust the posture of the main body 1, make the pressure detection head 31 face the vehicle window frame, adjust the gap between the main body 1 and the clamping plate 21 through the adjusting piece 22, make the main body 1 and the clamping plate 21 clamp the vehicle window glass, then control the vehicle window glass to rise until the pressure detection head 31 abuts against the vehicle window frame, read the pressure data detected by the pressure detection mechanism 3 after the vehicle triggers the vehicle window anti-pinch protection mechanism, if the test result of the pressure detection mechanism 3 is less than 100N, the vehicle glass clamping force passes the test, and if the test result of the pressure detection mechanism 3 is greater than 100N, the vehicle glass clamping force does not pass the test.

[0029] The present application adjusts the distance between the clamping plate 21 and the main body 1 through the adjusting piece 22, clamps the vehicle window glass by the clamping plate 21 and the main body 1, so that the vehicle glass clamping force measuring device can be stably clamped on the vehicle window glass, thereby realizing the clamping force measurement of the vehicle window glass at any opening position, ensuring the accuracy of the measurement result and the consistency of the measurement result, and the whole device has a small size and is convenient for the detector to carry, and the worker does not need a complex installation process, but only needs to adjust the distance between the clamping plate 21 and the main body 1 according to the thickness of the vehicle glass to install the device on the vehicle window glass to be tested.

[0030] Referring to Figure 1 The vehicle glass clamping force measuring device further comprises an extension plate 4, the extension plate 4 is fixed opposite to the pressure detection head 31, the extension plate 4 is provided with a through hole, the pressure detection head 31 passes through the through hole, the extension plate 4 can be detached from the pressure detection head 31, and the surface of the extension plate 4 is parallel to the direction of the clamping plate 21. The extension plate 4 can increase the force receiving area of the pressure detection head 31, so that the measurement is more accurate. When the vehicle window glass rises, the vehicle window frame can easily apply pressure to the pressure detection head 31 through the extension plate 4. The extension plate 4 is in a strip shape, the length direction of the extension plate 4 is the same as the direction of the clamping plate 21, and the extension plate 4 is more likely to contact the vehicle window frame when the vehicle window glass rises.

[0031] See Figures 1-3 The automotive glass clamping force measuring device also includes an extension rod 5. One end of the extension rod 5 is detachably connected to the pressure probe 31, and the other end of the extension rod 5 is detachably connected to the extension plate 4. By adding the extension rod 5 to the pressure probe 31, the pressure detection mechanism 3 can measure the window opening within a range of 4 mm to 200 mm. When it is necessary to detect the clamping force of a larger window opening, the extension rod 5 can be installed on the pressure probe 31, and the extension plate 4 can be installed at the end of the extension rod 5 away from the pressure probe 31. After the main body 1 is installed on the window glass, when the window glass rises, the outer frame of the window contacts the extension plate 4 and applies pressure to the extension plate 4. The pressure is transmitted to the pressure probe 31 through the extension rod 5, thereby enabling the pressure probe 31 to detect the clamping force of a larger window opening.

[0032] See Figures 1-3 When the extension plate 4 is directly mounted on the pressure probe 31, the gap width between the window glass and the window frame is approximately the diameter of a human finger when the extension plate 4 contacts the window frame. At this point, the automotive glass clamping force measuring device can detect the clamping force when a human finger is clamped between the window glass and the window frame. The extension rod 5 comes in two lengths: 50-70mm and 140-160mm. See also... Figure 2 When an extension rod 5 with a length of 50-70mm is installed on the pressure probe 31, and then an extension plate 4 is installed on the extension rod 5, the gap width between the window glass and the window frame when the extension plate 4 contacts the window frame is approximately the diameter of a human wrist. At this point, the automotive glass clamping force measuring device can detect the magnitude of the clamping force when a wrist diameter is clamped between the window glass and the window frame. See also Figure 3 When an extension rod 5 with a length of 140~160mm is installed on the pressure probe head 31, and then an extension plate 4 is installed on the extension rod 5, when the extension plate 4 contacts the outer frame of the car window, the gap width between the car window glass and the outer frame of the car window is approximately the diameter of a human neck. At this time, the car window clamping force measuring device can detect the magnitude of the clamping force when the neck diameter is clamped by the car window glass and the outer frame of the car window.

[0033] See Figure 1In some embodiments, the clamping mechanism 2 further includes an adjusting bolt. The adjusting member 22 has a hollow hole 221, which is elongated and extends in the same direction as the clamping plate 21. The adjusting bolt passes through the hollow hole 221 and is screwed onto the main body 1. The adjusting member 22 is fixed to the main body 1 by the adjusting bolt. When it is necessary to adjust the distance between the clamping plate 21 and the main body 1, the operator can loosen the adjusting bolt and slide the adjusting member 22 along the extension direction of the hollow hole 221 until the distance between the clamping plate 21 and the main body 1 reaches the required size. Then, the operator tightens the adjusting bolt to fix the adjusting member 22 to the main body 1, thus fixing the distance between the clamping plate 21 and the main body 1. When the car window glass extends into the gap between the clamping plate 21 and the main body 1, the operator can tighten the adjusting bolt to firmly clamp the car window glass between the clamping plate 21 and the main body 1.

[0034] See Figures 1-2 The adjusting component 22 and the pressure probe 31 are located on the same side of the main body 1. The adjusting component 22 has a clearance hole 222 through which the pressure probe 31 passes. The clearance hole 222 can prevent the adjusting component 22 from interfering with the pressure probe 31. The pressure detection mechanism 3 also includes a transition platform 32, a bridge sensor 33, and a base 34. The transition platform 32, the bridge sensor 33, and the base 34 are located inside the main body 1. The base 34 is fixed to the main body 1. The bridge sensor 33 is installed on the base 34. The transition platform 32 is fixed to the bridge sensor 33 by screws. The transition platform 32 is fixed to the pressure probe 31 by screws. The base 34 is fixed to the main body 1 by screws.

[0035] See Figure 1 The main body 1 is equipped with a data interface 11, and the bridge sensor 33 is electrically connected to the data interface 11 via a wire. The data interface 11 can be connected to an external display via a wire, and the bridge sensor 33 can send the detected data to the external display, which will then display the clamping force value.

[0036] Corresponding to the aforementioned application function implementation device embodiments, this application also provides a detection method and corresponding embodiments using an automotive glass clamping force measuring device.

[0037] See Figure 1 The detection method using an automotive glass clamping force measuring device includes the following steps: Lower the car window glass; adjust the distance between the clamping plate 21 and the main body 1 using the adjusting component 22, so that the car window glass is between the clamping plate 21 and the main body 1, and point the pressure probe 31 toward the outer frame of the car window; reduce the distance between the clamping plate 21 and the main body 1 using the adjusting component 22, so that the car window glass is clamped between the clamping plate 21 and the main body 1; raise the car window glass, so that the pressure probe 31 touches the outer frame of the car window, triggering the anti-pinch protection mechanism of the car window; obtain the data detected by the pressure detection mechanism 3.

[0038] To ensure accurate measurement results, each car window needs to be measured at two different locations. For the car door windows, the two locations with the gentlest slope and the steepest slope need to be measured. For the car sunroof, the two locations with the center and the outermost edge of the window need to be measured.

[0039] When judging the measurement results, each car door window and sunroof will have six peak clamping force data points with two measurement positions and three opening sizes. The maximum value of these six peak forces is taken as the clamping force test result for that car window glass. If the test result is less than 100N, it passes; otherwise, it fails. The above test is performed on each car door window and sunroof. Only when all the results are passing, is the car model considered to have passed the automotive glass clamping force test.

[0040] This application adjusts the distance between the clamping plate 21 and the main body 1 by adjusting the adjusting member 22, so that the clamping plate 21 and the main body 1 clamp the car window glass, so that the car window clamping force measuring device can be firmly clamped on the car window glass, thereby realizing the clamping force measurement at any opening position of the car window glass, ensuring the accuracy of the measurement results, and ensuring the consistency of the measurement results.
