Description

Technical Field

[0001] This utility model relates to the field of automotive testing technology, and more specifically, to a tooling for simulating the sliding resistance of a window glass guide groove sealing strip. Background Technology

[0002] Car windows are an important component of automobiles. The window glass is sealed to the glass guide channel by a weatherstripping, and the sealing performance of the weatherstripping is crucial for the overall sound insulation of the vehicle. To ensure that the weatherstripping in the glass guide channel does not suffer excessive wear due to excessive sliding resistance during the raising and lowering of the window glass, thus preventing seal failure, it is necessary to conduct a sliding resistance test on the weatherstripping.

[0003] Existing testing fixtures for the sliding resistance of automotive window guide channel seals typically include two relatively fixed U-shaped guide rails. The seal to be tested is placed inside the U-shaped guide rails, and the glass slides along the length of the U-shaped guide rails to simulate the process of raising and lowering the window glass in its natural installation state or when the car door is open. However, in reality, the window glass is usually raised and lowered when the car door is closed. At this time, the car body will exert a compressive force on the window glass guide channel seal in the longitudinal direction of the vehicle, that is, the window glass guide channel seal will be subjected to lateral pressure. This pressure will also affect the sliding resistance of the window glass guide channel seal. Therefore, existing testing fixtures usually cannot accurately measure the sliding resistance of the window glass guide channel seal. Utility Model Content

[0026] like Figures 1-2 As shown in the figure, a simulation test fixture for the sliding resistance of a sealing strip in a car window glass guide groove according to an embodiment of the present invention includes a base plate 1, a first U-shaped guide rail 2, a second U-shaped guide rail 3, a first driving member 4, a second driving member 5, and a pressure detection device 6. The first U-shaped guide rail 2 and the second U-shaped guide rail 3 are respectively used to place the sealing strip 13. The first U-shaped guide rail 2 and the second U-shaped guide rail 3 are arranged opposite to each other on the base plate 1, and the grooves of the first U-shaped guide rail 2 and the second U-shaped guide rail 3 face each other to the same side. The first U-shaped guide rail 2 is fixedly connected to the base plate 1. The second U-shaped guide rail 3 is connected to one end of the pressure detection device 6, and the other end of the pressure detection device 6 is connected to the first driving member 4. The first driving member 4 is used to drive the second U-shaped guide rail 3 to move in a direction closer to or away from the first U-shaped guide rail 2. The second driving member 5 is used to drive the glass sheet 14 to move along the length direction of the first U-shaped guide rail 2 and the second U-shaped guide rail 3.

[0027] Specifically, the base plate 1 provides a supporting foundation for the first U-shaped guide rail 2, the second U-shaped guide rail 3, and the first driving component 4. The base plate 1 can be set along the YZ plane. The first U-shaped guide rail 2 and the second U-shaped guide rail 3 are spaced apart and opposite to each other along the Y direction. The first U-shaped guide rail 2 and the second U-shaped guide rail 3 both extend along the Z direction, that is, the length direction of the first U-shaped guide rail 2 and the second U-shaped guide rail 3 is the Z direction. The projection of the first U-shaped guide rail 2 and the second U-shaped guide rail 3 on the XY plane is U-shaped. The slots of the first U-shaped guide rail 2 and the slots of the second U-shaped guide rail 3 face each other to the side that is close to each other. That is, the slot of the first U-shaped guide rail 2 faces the side that is close to the second U-shaped guide rail 3, and the slot of the second U-shaped guide rail 3 faces the side that is close to the first U-shaped guide rail 2. The sealing strip 13 can be a U-shaped sealing strip, and it matches the shape of the first U-shaped guide rail 2 and the second U-shaped guide rail 3. The sealing strip 13 can be inserted into the first U-shaped guide rail 2 or the second U-shaped guide rail 3 from one end of the length direction of the first U-shaped guide rail 2 or the second U-shaped guide rail 3.

[0028] The first driving component 4 and the second driving component 5 can adopt existing technologies, as long as they can provide driving force. The second U-shaped guide rail 3 can move along the Y direction under the drive of the first driving component 4 to move closer to or away from the first U-shaped guide rail 2. The second driving component 5 can drive the glass plate 14 to move along the Z direction.

[0029] In this embodiment, the first U-shaped guide rail 2 and the second U-shaped guide rail 3 are used to simulate the guide groove of the car window glass. The first U-shaped guide rail 2 and the second U-shaped guide rail 3 are arranged opposite to each other on the base plate 1, and the grooves of the first U-shaped guide rail 2 and the second U-shaped guide rail 3 face each other. The first U-shaped guide rail 2 and the second U-shaped guide rail 3 are respectively provided with sealing strips 13, which are sealing strips for the car window glass guide groove. The glass sheet 14 can be inserted between the first U-shaped guide rail 2 and the second U-shaped guide rail 3 from one end along the length direction of the first U-shaped guide rail 2 and the second U-shaped guide rail 3, and move along the length direction of the first U-shaped guide rail 2 and the second U-shaped guide rail 3 under the drive of the second driving member 5, so as to simulate the car window glass in the car window glass guide groove. The process of internal lifting; moreover, the first U-shaped guide rail 2 is fixed on the base plate 1, the second U-shaped guide rail 3 is connected to the pressure detection device 6, the pressure detection device 6 is connected to the first driving component 4, the first driving component 4 can drive the second U-shaped guide rail 3 to move towards the first U-shaped guide rail 2, so as to simulate the state of the sealing strip being compressed when the door is closed, and the driving force applied by the first driving component 4 to the second U-shaped guide rail 3, that is, the lateral pressure on the sealing strip 13, can be measured in real time by the pressure detection device 6, so as to facilitate the simulation of the lateral pressure on the sealing strip 13 under different vehicle models and closing forces, and realize a more accurate simulation test of the sealing strip 13, and the sliding resistance test results of the sealing strip 13 are more accurate.

[0030] Optionally, the first driving component 4 is a cylinder. The cylinder moves relatively smoothly, can provide greater output power, and can generate force and movement quickly. The first driving component 4 can be a high-precision cylinder, so that the first driving component 4 can quickly drive the second U-shaped guide rail 3 to move, so as to accurately control the pressure of the sealing strip 13.

[0031] like Figures 1-3 As shown, optionally, the simulation test fixture for the sliding resistance of the window glass guide groove sealing strip also includes a controller 7 and a valve 8. The valve 8 is located at the air inlet of the cylinder. The controller 7 is signal-connected to the valve 8 and the pressure detection device 6. The controller 7 is used to adjust the opening of the valve 8 according to the pressure signal detected by the pressure detection device 6.

[0032] In this embodiment, valve 8 can be an electrically controlled valve. Controller 7 can receive the pressure signal detected by pressure detection device 6 and send a control signal to valve 8 to make valve 8 move, thereby adjusting the opening range of valve 8 and adjusting the air intake of cylinder to achieve control of cylinder output force.

[0033] Different vehicle models or door closing forces will exert different pressures on the sealing strip 13. When it is necessary to measure the sliding resistance of the sealing strip 13 under a predetermined pressure value, the controller 7 collects the actual pressure signal detected by the pressure detection device 6 and compares the actual measured pressure signal with the predetermined pressure value. If the actual measured pressure signal is less than the predetermined pressure value, the controller 7 increases the opening of the valve 8 to increase the air intake of the cylinder, thereby increasing the output power of the cylinder until the actual pressure signal detected by the pressure detection device 6 equals the predetermined pressure value. If the actual measured pressure signal is greater than the predetermined pressure value, the controller 7 decreases the opening of the valve 8 to decrease the air intake of the cylinder, thereby decreasing the output power of the cylinder until the actual pressure signal detected by the pressure detection device 6 equals the predetermined pressure value.

[0034] It should be noted that initially, the sealing strip 13 is not subjected to any lateral pressure, meaning the initial measurement value of the pressure detection device 6 is zero. When the first driving component 4 starts to drive, the sealing strip 13 begins to be compressed, and the pressure detection device 6 monitors the actual pressure on the sealing strip 13 in real time. At the end of the test, the first driving component 4 drives the second U-shaped guide rail 3 back to its initial position, at which point the pressure on the sealing strip 13 within the first and second U-shaped guide rails is zero.

[0035] Optionally, the valve 8 is a gas proportional valve; and / or, the pressure detection device 6 is a pressure sensor. The gas proportional valve has a good response speed and can be continuously adjusted according to the input signal, providing precise flow and pressure control. The use of a gas proportional valve in valve 8 allows it to operate quickly and accurately according to the instructions of the controller 7. The pressure sensor has high sensitivity and a fast response. The pressure detection device 6 uses a pressure sensor, such as an S-type sensor, which can conveniently and accurately detect the magnitude of the driving force output by the first driving element 4.

[0036] like Figures 1-2 As shown, optionally, the sliding resistance simulation test fixture for the window glass guide groove sealing strip also includes a sliding component 9. The sliding component 9 includes a slide rail 901 and a slider 902.

[0037] Specifically, the slide rail 901 extends along the Y direction, the slider 902 is slidably mounted on the slide rail 901, and the second U-shaped guide rail 3 is fixed on the slider 902. The second U-shaped guide rail 3 can move along the slide rail 901 together with the slider 902 to achieve sliding guidance of the second U-shaped guide rail 3 and prevent the second U-shaped guide rail 3 from shaking during the movement.

[0038] like Figure 2 As shown, optionally, the sliding assembly 9 further includes a sliding plate 903, a plurality of slide rails 901 are spaced apart along the movement direction of the glass sheet 14, the sliders 902 are arranged in a one-to-one correspondence with the slide rails 901, the sliding plate 903 extends along the movement direction of the glass sheet 14, and the sliding plate 903 is fixedly connected to the sliders 902 on the plurality of slide rails 901.

[0039] Specifically, multiple slide rails 901 are spaced apart along the Z-direction. For example, there may be two slide rails 901 spaced apart along the Z-direction. Each slide rail 901 is provided with a slider 902. A sliding plate 903 extends along the Z-direction and has a large Z-direction dimension, which can connect with the corresponding sliders 902 on multiple slide rails 901 at the same time. Multiple sliders 902 are connected together through the sliding plate 903 so that the first driving member 4 drives multiple sliders 902 to move synchronously along the Y-direction. The sliders 902 are connected to the second U-shaped guide rail 3 so that the second U-shaped guide rail 3 can move smoothly along the Y-direction under the guidance of multiple sliders 902 and slide rails 901, ensuring the movement stability of the second U-shaped guide rail 3.

[0040] like Figures 1-2As shown, optionally, the middle part of the sliding plate 903 is connected to the first driving member 4.

[0041] Specifically, the sliding plate 903 can be a rectangular plate, and the middle part of the sliding plate 903 refers to the geometric center of the sliding plate 903. By connecting the first driving member 4 to the middle part of the sliding plate 903, the force on the sliding plate 903 is more uniform, and the motion stability of the second U-shaped guide rail 3 is better.

[0042] like Figure 2 As shown, optionally, the window glass guide groove sealing strip sliding resistance simulation test fixture also includes a fixing plate 10, which is fixed on the base plate 1, and the side of the first U-shaped guide rail 2 facing away from the second U-shaped guide rail 3 is attached and fixed to the fixing plate 10.

[0043] Specifically, the fixing plate 10 can be integrally formed with the base plate 1. The fixing plate 10 is arranged along the XZ direction. The fixing plate 10 is attached and fixed to the side of the first U-shaped guide rail 2 that is away from the second U-shaped guide rail 3, that is, the side of the first U-shaped guide rail 2 that is away from the slot, so as to fix the first U-shaped guide rail 2 on the base plate 1.

[0044] Optionally, the second driving component 5 is a linear driving mechanism, and the output shaft 51 of the linear driving mechanism is provided with a slot for clamping the glass sheet 14. The linear driving mechanism can be a linear motor, which is located above the base plate 1. The output shaft 51 of the linear motor can be provided with a U-shaped slot facing downward at the end for contacting the glass sheet 14. The output shaft 51 of the linear motor can be engaged with the glass sheet 14 through the slot to prevent the linear motor from deviating when driving the glass sheet 14 to move up and down.

[0045] like Figure 1 As shown, optionally, the window glass guide groove sealing strip sliding resistance simulation test fixture also includes a support platform 11 and a column 12. The base plate 1 is vertically arranged on the support platform 11, and the column 12 is respectively provided on both sides of the base plate 1 on the support platform 11. The second driving member 5 is installed between the two columns 12.

[0046] Specifically, the support platform 11 is set along the XY plane, and the base plate 1 is set vertically on the support platform 11 and can be fixedly connected to the support platform 11 or the column 12. The column 12 extends along the Z direction, and the base plate 1 has columns 12 on both sides in the Y direction. The upper end of the column 12 extends beyond the base plate 1. A second driving component 5 is installed between the upper ends of the two columns 12, so that the second driving component 5 is set above the first U-shaped guide rail 2 and the second U-shaped guide rail 3, so as to facilitate the use of the second driving component 5 to drive the glass piece 14 between the first U-shaped guide rail 2 and the second U-shaped guide rail 3 to move up and down, so as to simulate the vertical lifting and lowering movement of the car window glass.

[0047] Although the present invention has been disclosed above, its protection scope is not limited thereto.
