[0024] This application is based on the inventor's discovery and understanding of the following facts and problems:

[0025] In low-temperature environments, the sliding doors of commercial vehicles are prone to the problem that the dashboard does not prompt "door not closed" after the door is opened and the vehicle is started.

[0026] After extensive research, the inventor discovered that the door-controlled switch of a sliding door is prone to being unable to rebound after being squeezed in a low-temperature environment. As a result, the software still believes that the door is in a closed state after the sliding door is opened, resulting in the dashboard not prompting "door not closed" when starting the vehicle.

[0027] Performing fatigue endurance tests on gate-controlled switches helps to test and verify the performance of gate-controlled switches and assists in improving them.

[0028] The switch test device in the related art lacks the function of performing fatigue durability test on the switch under low temperature conditions and cannot meet the requirements of fatigue durability test of the switch in low temperature environment.

[0032] A switch testing device 1 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0033] like Figure 1 and Figure 2 As shown, the switch testing device 1 according to the embodiment of the present invention includes a temperature regulating chamber, a test switch 10 , a switch driving device 20 and a counting device 30 .

[0034] The test switch 10 is suitable for being placed in the temperature regulating chamber. The switch driving device 20 is suitable for switching the test switch 10 between a trigger state and a non-trigger state. The counting device 30 is suitable for recording the number of times the switch driving device 20 switches the test switch 10 to the trigger state.

[0035] Specifically, the temperature regulating chamber is suitable for regulating the temperature inside the temperature regulating chamber so as to adjust the ambient temperature of the test switch 10 . The counting device 30 is electrically connected to the power supply 70 .

[0036] During the test, the test switch 10 is placed in the temperature-regulating chamber, which is adjusted to the desired test temperature. For example, the chamber can provide temperatures below room temperature to facilitate testing the durability fatigue performance of the test switch 10 in a low-temperature environment. Alternatively, the chamber can provide temperatures below room temperature, room temperature, and above room temperature to facilitate comparative testing. The switch driver 20 then drives the test switch 10 to switch between a triggered state and a non-triggered state, while a counting device 30 records the number of times the switch driver 20 switches the test switch 10 to the triggered state until the test switch 10 fails to switch normally to the non-triggered state, thereby obtaining the durability fatigue test data for the test switch 10.

[0037] According to the switch test device 1 of the embodiment of the present invention, by providing a switch driving device 20 and a counting device 30, the switch driving device 20 can be used to drive the test switch 10 to switch between a triggered state and a non-triggered state, and the counting device 30 can be used to record the number of times the switch driving device 20 switches the test switch 10 to the triggered state, until the test switch 10 cannot be normally switched to the non-triggered state, thereby obtaining the durability fatigue test data of the test switch 10, thereby facilitating the implementation of the durability fatigue test of the test switch, facilitating the testing and verification of the performance of the test switch, and assisting in improving the test switch.

[0038] Moreover, by setting up the temperature regulating chamber and placing the test switch 10 in the temperature regulating chamber, the ambient temperature of the test switch 10 can be adjusted by adjusting the temperature of the temperature regulating chamber, thereby providing the test switch 10 with the ambient temperature required for the test, thereby realizing a durability fatigue test of the test switch 10 at the temperature required for the test, improving the applicability of the switch testing device 1, and facilitating the improvement of the test switch through the durability fatigue test.

[0039] Therefore, the switch testing device 1 according to the embodiment of the present invention can meet the durability fatigue test requirements of switches under abnormal ambient temperatures, and has advantages such as strong applicability.

[0040] The switch testing device 1 according to a specific embodiment of the present invention will be described below with reference to the accompanying drawings.

[0041] In some specific embodiments of the present invention, Figure 1 and Figure 2 As shown, the switch testing device 1 according to the embodiment of the present invention includes a temperature regulating chamber, a test switch 10 , a switch driving device 20 and a counting device 30 .

[0042] Specifically, the switch driving device 20 is switchable between a compressed state and a released state. In the compressed state, the switch driving device 20 compresses the test switch 10 to the triggered state, and in the released state, the switch driving device 20 releases the test switch 10 to allow the test switch 10 to rebound to the non-triggered state. In this way, the switch driving device 20 can compress the test switch 10 to trigger the test switch 10, and release the test switch 10 to allow the test switch 10 to rebound to the non-triggered state, thereby facilitating the switch driving device 20 to drive the test switch 10 to switch between the triggered state and the non-triggered state.

[0043] More specifically, if Figure 2 As shown, the switch test device 1 further includes a mounting seat 40 and a pressure plate 50. The mounting seat 40 is disposed within the temperature regulating chamber, and the test switch 10 is adapted to be mounted on the mounting seat. The pressure plate 50 is slidably disposed on the mounting seat 40 between a compressed position and a released position. When in the compressed position, the pressure plate 50 compresses the test switch 10 into the triggered state. When in the released state, the pressure plate 50 disengages from the test switch 10 to allow the test switch 10 to rebound to the non-triggered state. The pressure plate 50 is connected to the switch drive device 20. When the switch drive device 20 is in the compressed state, the pressure plate 50 is in the compressed position. When the switch drive device 20 is in the released state, the pressure plate 50 is in the released position. Specifically, a guide rail 41 is provided on the mounting seat 40, and the pressure plate 50 is slidably disposed on the guide rail 41. In this way, the switch driving device 20 can compress the test switch 10 on the mounting seat 40 through the pressure plate 50, which is convenient for ensuring the relative position of the pressure plate 50 and the mounting seat 40, thereby ensuring the consistency of the compression direction of the test switch 10 and avoiding factors such as the component force generated during the compression process that affect the accuracy of the test results.

[0044] Furthermore, if Figure 1 As shown, the switch driving device 20 includes a cylinder 21, a solenoid valve 22 and a relay 23. The cylinder 21 drives the pressure plate 50 to move between the compression position and the release position. The solenoid valve 22 is connected to the cylinder 21 in an air circuit. The relay 23 is electrically connected to the power supply 70 and the solenoid valve 22. Specifically, the stroke of the cylinder 21 can be 7 mm. The solenoid valve 22 can control the movement direction of the cylinder 21, and the relay 23 can control the compression time of the cylinder 21 through the solenoid valve 22. For example, the cylinder 21 can be compressed for 2 seconds and then decompressed for 2 seconds, forming a cycle of 4 seconds. In this way, the cylinder 21 can be used to drive the pressure plate 50 to repeatedly compress and release the test switch 10, thereby realizing a fatigue endurance test of the test switch 10.

[0045] Advantageously, as Figure 2As shown, the mounting base 40 is suitable for mounting multiple test switches 10, and the pressing plate 50 is suitable for simultaneously compressing the multiple test switches 10 on the mounting base 40. This allows multiple identical test switches 10 to be tested simultaneously to eliminate test errors caused by individual differences. It also allows multiple different test switches 10 to be tested simultaneously to compare the fatigue durability of different test switches 10.

[0046] Figure 1 FIG1 shows a switch test device 1 according to some examples of the present invention. Figure 1 As shown, the switch test device 1 further includes a light-emitting element 60, which is electrically connected to a power source 70 via the test switch 10. This allows the state of the test switch 10 to be determined by whether the light-emitting element 60 is emitting light, thereby facilitating the determination of whether the test switch 10 can normally switch between the triggered and untriggered states. This facilitates recording the number of switching times to obtain fatigue durability performance data when the test switch 10 fails abnormally.

[0047] Advantageously, the light emitting element 60 is disposed outside the temperature control chamber. This allows for easy viewing of the status of the test switch 10 through the light emitting element 60 without the need to frequently open the temperature control chamber. This not only facilitates timely observation and recording of the test progress, but also prevents opening the temperature control chamber from affecting the temperature inside the temperature control chamber and causing changes in the ambient temperature of the test switch 10, thereby preventing the accuracy of the test results.

[0048] Optionally, the counting device 30 is a light-sensitive counting device. Specifically, the counting device 30 can be installed at a movable structure such as the cylinder 21 or the pressure plate 50. The counting device 30 records the number of times the movable structure moves by blocking light when the movable structure is in different positions, thereby reflecting the number of times the cylinder 21 compresses the test switch 10. This facilitates counting the number of times the test switch 10 is switched.

[0049] Specifically, the test switch 10 is a door control switch, so that a fatigue durability test can be performed on the door control switch, the fatigue durability performance of the door control switch can be tested and verified, and the improvement of the door control switch can be facilitated.

[0050] More specifically, the test switch 10 is a sliding door control switch, which can be used to perform fatigue durability tests on the sliding door control switch, test and verify the fatigue durability performance of the sliding door control switch, and assist in improving the sliding door control switch.

[0051] Specifically, the test switch 10 can be a vehicle sliding door control switch, and the temperature regulating chamber can provide a temperature below room temperature. This allows the switch testing device 1 to be used for fatigue endurance testing of vehicle sliding door control switches in low-temperature environments, helping to improve the performance of vehicle sliding door control switches in low-temperature environments and addressing the issue of vehicle sliding door control switches being unable to rebound in low-temperature environments.
