This can improve the control accuracy of the pressing operation structure, regulate the working state of the switch to be measured according to actual needs, and ensure that the durability performance of the switch to be measured can be accurately reflected. Among them, the first moving component 61 is connected to the slider 54. By adjusting the position of the slider 54 on the telescopic adjusting rod 51, the position of the first moving component 61 can be adjusted to meet the requirement that the second moving component 62 can be moved to a position corresponding to the adjusting component 3 in the pressing operation structure in the axial direction through the first moving component 61.

[0120] In one embodiment, referring to Figure 3 and Figure 4 , the first moving component 61 includes a first connecting seat 611 and a first actuator 612; the first end of the first connecting seat 611 is connected to the fixed member 5, the second end of the first connecting seat 611 is connected to the first actuator 612, and the telescopic rod of the first actuator 612 is connected to the first end of the second moving component 62.

[0121] As an example, the first moving component 61 includes a first connecting seat 611 and a first actuator 612. The first connecting seat 611 is an L-shaped footrest for connecting the first actuator 612 to the fixed member 5. The first actuator 612 is a linear electric cylinder, and its telescopic rod is connected to the first end of the second moving component 62. Such a setting can adjust the orientation position of the first actuator 612 through the fixed member 5 and adjust the position of the second moving component 62 by controlling the elongation of the telescopic rod of the first actuator 612.

[0122] In one embodiment, referring to Figure 4 , the second moving component 62 includes a second connecting seat 621, a second actuator 622, and a push head 623; the first end of the second connecting seat 621 is connected to the first moving component 61, the second end of the second connecting seat 621 is connected to the second actuator 622, the telescopic rod of the second actuator 622 is connected to the first end of the push head 623, and the second end of the push head 623 is connected to the adjusting component 3 in the pressing operation structure.

[0124] An embodiment of the present invention provides a pressing test system. Referring to Figures 1 - 9 , it includes a pressing test device and a control module 7; the control module 7 is connected to the action execution structure in the pressing test device for controlling the working state of the action execution structure.

[0125] As an example, the pressing test system includes a pressing test device and a control module 7. The pressing test device includes a pressing operation structure and an action execution structure, and the up-and-down movement of the switch under test is realized by the action of the action execution structure on the pressing operation structure. Taking the window lifter as the switch under test as an example, the fixed housing 1 is installed on the vehicle door, the sleeve 2 is installed on the fixed housing 1, the adjusting component 3 is assembled in the sleeve 2, and one end of it extends outside the sleeve 2 and is connected to the connecting block 4. The action execution structure is connected to the adjusting component 3 in the pressing operation structure for controlling the adjusting component 3. By controlling the working state of the adjusting component 3, adjusting its position in the sleeve 2, and driving the connecting block 4 to reciprocate along the axial direction of the sleeve 2, the connecting block 4 can control the working state of the window lifter on the vehicle door. This can improve the control accuracy of the pressing operation structure, regulate the working state of the window lifter according to actual needs, and ensure that the durability performance of the window lifter can be accurately reflected. The control module 7 is connected to the action execution structure in the pressing test device for controlling the working state of the action execution structure, so that the pressing operation structure can press precisely and retract when no pressing operation is required. The pressing operation structure acts directly on the window lifter, which can improve the control accuracy of the pressing operation structure, regulate the working state of the window lifter according to actual needs, and ensure that the durability performance of the window lifter can be accurately reflected.

[0126] The pressing test system in this example fills the gap in the verification of the durability system of the vehicle's glass lifter, and can be well applied to newly developed vehicle models. For the durability test of frameless glass lifters that cannot be tested on a test bench, it can simultaneously inspect the control of the glass lifter by the vehicle domain control system under various durability conditions, and can be tested together with other tests such as door durability to meet diverse test requirements and better simulate the actual user usage environment.

[0127] In one embodiment, referring to Figure 7 , the control module 7 includes a position sensor 71, a signal acquisition card 72, a controller 73, and a driver 74; the position sensor 71 is installed on the moving part 6 of the action execution structure for monitoring the position signal of the moving part 6; the signal acquisition card 72 is connected to the position sensor 71 for acquiring the position signal collected by the position sensor 71; the controller 73 is connected to the signal acquisition card 72 and the driver 74 for controlling the driver 74 to drive the moving part 6 to switch the working state according to the position signal sent by the signal acquisition card 72.

[0128] As an example, the control module 7 includes a position sensor 71, a signal acquisition card 72, a controller 73, and a driver 74. Position sensors 71 are installed on both the first actuator 612 and the second actuator 622 in the moving part 6 respectively for monitoring the position signals of the first actuator 612 and the second actuator 622; the signal acquisition card 72 is connected to the position sensors 71 for acquiring the position signals collected by the position sensors 71; the controller 73 is connected to the signal acquisition card 72 and the driver 74 for controlling the driver 74 to drive the first actuator 612 and the second actuator 622 to extend or retract according to the position signal sent by the signal acquisition card 72, and controlling the telescopic stroke of the first actuator 612 and the second actuator 622 through the position sensor 71, so that the pressing operation structure can accurately press and retract when no pressing operation is required. The pressing operation structure directly acts on the switch to be tested, which can improve the control accuracy of the pressing operation structure, regulate the working state of the switch to be tested according to actual needs, and ensure that the durability performance of the switch to be tested can be accurately reflected. Among them, the control module 7 also includes a regulated power supply, sensors, an alarm, etc. The computer is connected to the controller 73 through PCI, acquires and transmits each position signal through the signal acquisition card 72, and then controls the actuator to act through the driver 74 to operate the switch to be tested, such as the door glass lifter switch, to realize the control of the door glass lifter.

[0129] The embodiment of the present invention also provides a control method for a pressing test system. Referring to Figure 8 , applicable to the pressing test system, taking the controller 73 applicable in the above pressing test system as an example, the control method of the pressing test system includes the following steps:

[0130] S1: Control the movement of the action execution structure and monitor whether the current position corresponding to the action execution structure reaches the target position corresponding to the pressing operation structure;

[0131] S2: When the current position reaches the target position corresponding to the pressing operation structure, the action execution structure is used to control the pressing operation structure to perform a pressing test on the switch to be tested, and the working state of the pressing operation structure is switched.

[0132] The current position is the position of the action execution structure monitored in real time, and specifically, the position of the action execution structure relative to the pressing operation structure detected in real time. The target position is the position to be controlled by the action execution structure, and specifically, the position to be controlled to perform a pressing test on the pressing operation structure.

[0133] As an example, in step S1, the controller 73 controls the movement of the moving part 6 in the action execution structure, uses the position sensor 71 to monitor the position signal of the moving part 6 in the action execution structure in real time, and sends the position signal to the controller 73, so that the controller 73 can determine the current position corresponding to the action execution structure based on the position signal, and then determine whether the current position reaches the target position corresponding to the pressing operation structure. In this example, the target position corresponding to the pressing operation structure can be a position in contact with the pressing operation structure, or a position set in the axial direction of the pressing operation structure and less than a preset distance from it.

[0134] As an example, in step S2, when the current position of the moving part 6 in the action execution structure reaches the position in contact with the pressing operation structure, the controller 73 can control the moving part 6 of the action execution structure to extend or retract, thereby controlling the pressing operation structure to perform a pressing test on the switch to be tested, and switching the working state of the pressing operation structure to complete the durability test of the switch to be tested. In this example, the working state of the pressing operation structure includes an initial state, a pressing state, and a tilted state. In the process of controlling the pressing operation structure to perform a pressing test, its working state can be controlled to switch from the initial state to the pressing state, from the pressing state to the tilted state, and from the tilted state to the initial state, so as to complete a pressing test on the switch to be tested, and so on, to complete the durability test of the switch to be tested.

[0135] In this example, the controller 73 controls the working state of the pressing operation structure to switch from the initial state to the pressing state, from the pressing state to the tilted state, and from the tilted state to the initial state, to complete a pressing test operation, and can monitor the current number of presses; if the current number of presses reaches the preset number of presses, it is determined that the durability test of the switch to be tested is completed, and the moving component 6 in the action execution structure can be controlled to reset and end the action; if the current number of presses does not reach the preset number of presses, then the working state is repeatedly switched from the initial state to the pressing state, from the pressing state to the tilted state, and from the tilted state to the initial state.

[0136] In this embodiment, after using the action execution structure to control the press operation structure to perform a press test on the switch to be tested and switching the working state of the press operation structure, the control method of the press test system also includes: obtaining the current number of presses; if the current number of presses reaches the preset number of presses, controlling the action execution structure to reset; if the current number of presses does not reach the preset number of presses, using the action execution structure to control the press operation structure to continue to perform the press test on the switch to be tested.

[0137] In this embodiment, the press test system is a test device for the durability test of the glass lift of frameless car doors. The fixed component 5 in the action execution structure can be quickly adjusted to adapt to the installation inside the car body of different models. When the current position of the moving component 6 in the action execution structure reaches the target position of contact with the press operation structure, the controller 73 controls the moving component 6 of the action execution structure to extend or retract, thereby controlling the press operation structure to perform the press test, switching the working state of the press operation structure, thereby regulating the working state of the glass lifter, and completing the durability test of the switch to be tested. The press operation structure can directly operate the glass lifter on the car door, and is used in conjunction with the moving component 6. Without affecting the opening and closing of the car door, the whole vehicle glass lift durability test simulating the user is realized through the whole vehicle domain control system, which is closer to the actual use conditions.

[0138] In one embodiment, the moving component 6 in the action execution structure includes a first moving component 61 and a second moving component 62;

[0139] In step S1, the action execution structure is controlled to move, and monitoring whether the current position corresponding to the action execution structure reaches the target position corresponding to the pressing operation structure includes:

[0140] S11: Control the first actuator 612 in the first moving component 61 to extend along a first direction, and obtain a first current position of the first actuator 612;

[0141] S12: When the first current position reaches the first target position corresponding to the pressing operation structure, control the second actuator 622 in the second moving component 62 to extend along the second direction, and obtain the second current position of the second actuator 622.

[0142] S13: When the second current position reaches the second target position corresponding to the pressing operation structure, determine that the current position reaches the target position corresponding to the pressing operation structure.

[0143] Wherein, the first direction is the radial direction of the sleeve 2, the second direction is the axial direction of the sleeve 2, the moving component 6 includes a first moving component 61 and a second moving component 62, the first moving component 61 is arranged along the radial direction of the sleeve 2, and the second moving component 62 is arranged along the axial direction of the sleeve 2.

[0144] Wherein, the first current position is the current position where the first actuator 612 extends along the radial direction of the sleeve 2 detected in real time, specifically the position where the first actuator 612 is close to the end of the sleeve 2. The first target position is the position that the first actuator 612 needs to reach, specifically the position where the longitudinal projection of the current position where the first actuator 612 extends overlaps with the position of the pressing operation structure, so as to control the pressing operation structure to perform a pressing test at a subsequent position

[0145] Wherein, the second current position is the current position where the second actuator 622 extends along the axial direction of the sleeve 2 detected in real time, specifically the position where the second actuator 622 is close to the end of the pressing operation structure. The second target position is the position that the second actuator 622 needs to reach, specifically the position where the end of the second actuator 622 contacts the pressing operation structure, or the position where the distance between the two is less than a preset distance.

[0146] As an example, in step S11, the controller 73 controls the first actuator 612 in the first moving component 61 to start extending along the radial direction of the sleeve 2, uses the position sensor 71 to monitor the position signal of the first actuator 612 in real time, and sends the position signal to the controller 73, so that the controller 73 can determine the current position corresponding to the first actuator 612 based on the position signal.

[0147] As an example, in step S12, the control program in the controller 73 judges the current position of the first actuator 612. When the longitudinal projection of the current position where the first actuator 612 extends overlaps with the position of the pressing operation structure, the controller 73 controls the second actuator 622 in the second moving component 62 to extend along the axial direction of the sleeve 2, uses the position sensor 71 to monitor the position signal of the second actuator 622 in real time, and sends the position signal to the controller 73, so that the controller 73 can determine the current position corresponding to the second actuator 622 based on the position signal.

[0148] As an example, in step S13, the control program in the controller 73 determines the current position of the second actuator 622. When the current position where the second actuator 622 extends contacts the pressing operation structure, or when the distance between the current position where the second actuator 622 extends and the pressing operation structure is less than a preset distance, the current position corresponding to the action execution structure reaches the target position corresponding to the pressing operation structure at this time, and a pressing test can be performed on the pressing operation structure, thereby performing a durability test on the switch to be tested.

[0149] In this embodiment, the controller 73 controls the first actuator 612 in the first moving component 61 to start extending in the radial direction of the sleeve 2. The position sensor 71 is used to monitor the position signal of the first actuator 612 in real time and send the position signal to the controller 73, so that the controller 73 can determine the current position corresponding to the first actuator 612 based on the position signal. The control program in the controller 73 determines the current position of the first actuator 612. When the current position where the first actuator 612 extends overlaps with the longitudinal projection of the position of the pressing operation structure, the controller 73 controls the second actuator 622 in the second moving component 62 to extend in the axial direction of the sleeve 2. The position sensor 71 is used to monitor the position signal of the second actuator 622 in real time and send the position signal to the controller 73, so that the controller 73 can determine the current position corresponding to the second actuator 622 based on the position signal. The control program in the controller 73 determines the current position of the second actuator 622. When the current position where the second actuator 622 extends contacts the pressing operation structure, or when the distance between the current position where the second actuator 622 extends and the pressing operation structure is less than a preset distance, the working state of the adjusting component 3 is controlled by adjusting the telescopic movement of the second actuator 622, its position in the sleeve 2 is adjusted, and the connecting block 4 is driven to reciprocate in the axial direction of the sleeve 2, so that the connecting block 4 controls the working state of the window lifter on the vehicle door. In this way, the control accuracy of the pressing operation structure can be improved, the working state of the switch to be tested can be adjusted according to actual needs, and it is ensured that the durability performance of the switch to be tested can be accurately reflected.

[0150] In one embodiment, referring to Figure 9 , in step S2, the action execution structure is used to control the pressing operation structure to perform a pressing test on the switch to be tested and switch the working state of the pressing operation structure, including:

[0151] S21: When the pressing operation structure is in the initial state, the action execution structure is used to control the pressing operation structure to perform a first pressing operation and control the pressing operation structure to enter the pressing state;

[0152] S22: when the pressing operation structure is in the pressing state, the action execution structure is used to control the pressing operation structure to perform the lifting operation, so as to control the pressing operation structure to enter the lifting state;

[0153] S23: When the pressing operation structure is in the tilted state, the action execution structure is used to control the pressing operation structure to perform a second pressing operation, so as to control the pressing operation structure to enter the initial state.

[0154] The initial state of the pressing operation structure is that the limit boss of the rotating top rod 32 is stuck in the short limit tooth, and the switch to be tested is located in the middle position of the opening of the connecting block 4. The pressing state of the pressing operation structure is that the limit boss of the rotating top rod 32 is stuck outside the limit tooth, and the switch to be tested is connected to the upper inner wall of the opening of the connecting block 4. The lifting state of the pressing operation structure is that the limit boss of the rotating top rod 32 is stuck in the long limit tooth, and the switch to be tested is connected to the upper inner wall of the opening of the connecting block 4.

[0155] As an example, in step S21, when the pressing operation structure is in the initial state, the controller 73 controls the moving part 6 in the action execution structure to extend, presses the pressing operation structure to perform the first pressing operation, and switches the working state of the pressing operation structure to the pressing state. Specifically, the controller 73 controls the moving part 6 in the action execution structure to extend, presses the pressure rod 33, pushes the rotating top rod 32 down, drives the connecting rod core 31 and the connecting block 4 to descend and press the switch to be tested until the pressing position, and the adjusting teeth drive the rotating top rod 32 to rotate an angle through the limiting boss, so that it rotates and slides into the long limiting teeth; the working state of the pressing operation structure is switched from the initial state to the pressing state, and the adjusting component 3 switches the connecting block 4 from the initial position to the pressing position, pressing the switch to be tested on the first workpiece.

[0156] As an example, in step S22, when the pressing operation structure is in the pressing state, the controller 73 controls the moving part 6 in the action execution structure to tilt up, and the pressing operation structure performs the tilting operation, and switches the working state of the pressing operation structure to the tilting state. Specifically, the controller 73 controls the moving part 6 in the action execution structure to retract and move away from the pressure rod 33, so that the pressure rod 33 is not compressed, the connecting rod core 31 is lifted by the spring 34, and the limiting boss of the rotating top rod 32 slides upward in the long limiting tooth, and the working state of the pressing operation structure is switched from the pressing state to the tilting state, and the adjustment component 3 switches the connecting block 4 from the pressing position to the tilting position, and the switch to be tested on the first workpiece is tilted until it reaches the tilting position.

[0157] As an example, in step S23, when the pressing operation structure is in the warped state, the controller 73 controls the moving part 6 in the action execution structure to extend, presses the pressing operation structure to perform the second pressing operation, and switches the working state of the pressing operation structure to the initial state. Specifically, the controller 73 controls the moving part 6 in the action execution structure to extend, presses the pressing rod 33 again, pushes the rotating ejector rod 32 to descend, drives the connecting rod core 31 and the connecting block 4 to descend and press the switch to be measured until the reset position, and the adjusting tooth drives the rotating ejector rod 32 to rotate by an angle through the limit boss, so that it rotates and slides into the short limit tooth, and the working state of the pressing operation structure is switched from the warped state to the initial state, and the adjusting assembly 3 makes the connecting block 4 switch from the warped position to the initial position, completing a cyclic action.

[0158] In this embodiment, the controller 73 controls the moving part 6 in the action execution structure to extend or retract, controls the adjusting assembly 3 in the pressing operation structure to perform the first pressing operation, the warping operation and the second pressing operation, adjusts its position in the sleeve 2, and drives the connecting block 4 to reciprocate along the axial direction of the sleeve 2, so that the connecting block 4 regulates the working state of the switch to be measured on the first workpiece, which can improve the control accuracy of the pressing operation structure, regulate the working state of the switch to be measured according to actual requirements, and ensure that the durability performance of the switch to be measured on the first workpiece can be accurately reflected.

[0159] In one embodiment, in step S21, the action execution structure is used to control the pressing operation structure to perform the first pressing operation and switch the working state of the pressing operation structure to the pressing state, including:

[0160] Controlling the second actuator 622 to start extending to press the pressing operation structure, obtaining the measured position of the pressing operation structure, and when the measured position reaches the pressing position of the pressing operation structure, the second actuator 622 stops extending, and controls the pressing operation structure to enter the pressing state;

[0161] In step S21, the action execution structure is used to control the pressing operation structure to perform the warping operation and control the pressing operation structure to enter the warping state, including:

[0162] Controlling the second actuator 622 to start retracting without pressing the pressing operation structure, obtaining the measured position of the pressing operation structure, and when the measured position reaches the warping position of the pressing operation structure, the second actuator 622 stops extending, and controls the pressing operation structure to enter the warping state;

[0163] In step S21, the action execution structure is used to control the pressing operation structure to perform the second pressing operation and control the pressing operation structure to enter the initial state, including:

[0164] The second actuator 622 is controlled to start extending without pressing the pressing operation structure, and the measured position of the pressing operation structure is obtained. When the measured position reaches the initial position of the pressing operation structure, the second actuator 622 stops extending, and the pressing operation structure is controlled to enter the initial state.

[0165] In one example, the controller 73 controls the second actuator 622 to start extending, and uses the position sensor 71 to monitor the position signal of the second actuator 622 in real time, and sends the position signal to the controller 73, so that the controller 73 can determine the current position corresponding to the second actuator 622 based on the position signal, thereby obtaining the measured position of the pressing operation structure. The control program in the controller 73 determines whether the measured position of the pressing operation structure is in the pressing position, thereby determining whether to switch the measured position of the working state of the pressing operation structure. When the current position of the extension of the second actuator 622 makes the measured position of the pressing operation structure reach the pressing position, the position sensor 71 is used to monitor the position signal of the second actuator 622 in real time, and the position signal is sent to the controller 73, and the controller 73 controls the second actuator 622 to stop extending, and the working state of the pressing operation structure is switched from the initial state to the pressing state.

[0166] In this embodiment, the controller 73 controls the second actuator 622 in the movable part 6 to extend, and the pressing rod 33 in the adjusting component 3 in the pressing operation structure is pressed, pushing the rotating top rod 32 to descend, driving the connecting rod core 31 and the connecting block 4 to descend and press the switch to be tested until the pressing position, and the adjusting teeth drive the rotating top rod 32 to rotate an angle through the limiting boss, so that it rotates and slides into the long limiting teeth; the working state of the pressing operation structure is switched from the initial state to the pressing state, and the adjusting component 3 switches the connecting block 4 from the initial position to the pressing position, pressing the switch to be tested on the first workpiece until the pressing position.

[0167] In one example, the controller 73 controls the second actuator 622 to start retracting, and uses the position sensor 71 to monitor the position signal of the second actuator 622 in real time, and sends the position signal to the controller 73, so that the controller 73 can determine the current position corresponding to the second actuator 622 based on the position signal, thereby obtaining the measured position of the pressing operation structure. The control program in the controller 73 determines whether the measured position of the pressing operation structure is in the tilting position, that is, the switch to be tested is fully opened, thereby determining whether to switch the measured position of the working state of the pressing operation structure. When the current position of the retracted second actuator 622 makes the measured position of the pressing operation structure reach the tilting position, the position sensor 71 is used to monitor the position signal of the second actuator 622 in real time, and the position signal is sent to the controller 73, and the controller 73 controls the second actuator 622 to stop retracting, and the working state of the pressing operation structure is switched from the pressing state to the tilting state.

[0168] In this embodiment, the controller 73 controls the second actuator 622 in the movable part 6 to retract, and the pressing rod 33 and the connecting rod core 31 in the adjusting component 3 in the pressing operation structure rise under the action of the spring 34, and the limiting boss of the rotating top rod 32 slides upward in the long limiting tooth. The working state of the pressing operation structure is switched from the pressing state to the lifting state, and the adjusting component 3 switches the connecting block 4 from the pressing position to the lifting position, lifting the switch to be tested on the first workpiece until it reaches the lifting position.

[0169] In one example, the controller 73 controls the second actuator 622 to start extending, and uses the position sensor 71 to monitor the position signal of the second actuator 622 in real time, and sends the position signal to the controller 73, so that the controller 73 can determine the current position corresponding to the second actuator 622 based on the position signal, thereby obtaining the measured position of the pressing operation structure. The control program in the controller 73 determines whether the measured position of the pressing operation structure is in the initial position, that is, the switch to be tested is completely closed, so as to determine whether to switch the measured position of the working state of the pressing operation structure. When the current position of the extension of the second actuator 622 makes the measured position of the pressing operation structure reach the initial position, the position sensor 71 is used to monitor the position signal of the second actuator 622 in real time, and the position signal is sent to the controller 73, and the controller 73 controls the second actuator 622 to stop extending, and the working state of the pressing operation structure is switched from the tilted state to the initial state.

[0170] In this embodiment, the controller 73 controls the second actuator 622 in the movable part 6 to extend again, and the pressing rod 33 in the adjusting component 3 in the pressing operation structure is pressed to the initial position, pushing the rotating top rod 32 to descend, driving the connecting rod core 31 and the connecting block 4 to descend and press the switch to be tested until the reset position, and the adjusting tooth drives the rotating top rod 32 to rotate an angle through the limiting boss, so that it rotates and slides into the short limiting tooth, and the working state of the pressing operation structure is switched from the tilted state to the initial state, and the adjusting component 3 switches the connecting block 4 from the tilted position to the initial position, completing a cycle.

[0171] The method of the pressing test system in this embodiment is applied to the test of the window regulator and can also be combined with the car door to form a composite test of the car door glass, including the following steps: Open the car door, and the car door glass descends slightly; When the car door is opened to the maximum position, the car door glass stops descending; Close the car door, and the car door glass rises slightly to the initial position; Then obtain the initial state of the pressing operation structure and the current position of the moving part 6 in the action execution structure; Judge whether the current position is in place; If the current position is in place, control the moving part 6 to press the pressing operation structure and obtain the measured position of the pressing operation structure; Judge whether the measured position meets the preset conditions; If the measured position meets the preset conditions, control the moving part 6 to stop acting, and the pressing operation structure switches from the initial state to the pressing state; Control the moving part 6 to lift the pressing operation structure and obtain the measured position of the pressing operation structure; Judge whether the measured position meets the preset conditions; If the measured position meets the preset conditions, control the moving part 6 to stop acting, and the pressing operation structure switches from the pressing state to the lifting state; Control the moving part 6 to press the pressing operation structure and obtain the measured position of the pressing operation structure; Judge whether the measured position meets the preset conditions; If the measured position meets the preset conditions, control the moving part 6 to stop acting, and the pressing operation structure switches from the lifting state to the initial state; Judge whether the pressing operation structure returns to the initial state; If the pressing operation structure returns to the initial state, control the moving part 6 to reset and end the action. The pressing test system in this example is a test device for the durability test of the frameless car door glass. Through the fixing part 5, it can be quickly adjusted and adapted to be installed inside the body of different vehicle models. Through the pressing operation structure, key operations can be directly performed on the car door and used in cooperation with the moving part 6. Without affecting the opening and closing of the car door, through the vehicle domain control system, the durability test of the vehicle's glass lifting by simulating the user is realized, which is closer to the actual use conditions; On the basis of the original durability test of the window regulator, a composite test scheme for the opening and closing of the car door and the lifting of the glass can be carried out to comprehensively evaluate the vibration impact and lifting durability of the window regulator.
