The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0029] like Figure 1 to Figure 2 As shown, this embodiment provides an automated switch durability test device, which includes a test frame 1, a drive unit 2, a detection unit 3 and a control unit. The drive unit 2 is arranged on the test frame 1; the detection unit 3 includes a first detection component 31, a second detection component 32 and a third detection component 33 arranged at intervals on the test frame 1, and the first detection component 31, the second detection component 32 and the third detection component 33 are all connected to the drive unit 2 in a transmission manner, and the drive unit 2 can drive the first detection component 31, the second detection component 32 and the third detection component 33 to move; the control unit is electrically connected to the drive unit 2, and the control unit controls the drive unit 2 to work.

In addition, the control part is electrically connected to the driving part 2, so that the on-off and motion state of the driving part 2 can be controlled by the control part, thereby achieving the purpose of the test, wherein it also has the function of autonomously recording the number of tests, on-off time and the like. The use of the automatic switch durability detection test device of the present invention effectively solves the problem that the automatic switch durability detection test device in the prior art has a single type of detection switches and a high production cost.

For example, if it is replaced with a flexible trigger head, a durability test of the vehicle-mounted terminal screen can be carried out; if it is replaced with an adjustable torque trigger head, a fixed torque test can be carried out.

[0032] In some embodiments, the first detection component 31 is configured to detect the number of rotations of the rotary switch 4, and the first detection component 31 includes a first fixing member 311, a first detection member 312, and a second detection member 313.

With such an arrangement, the driving unit 2 can drive the first detection member 312 and the second detection member 313 to move in the opposite direction in the vertical direction, thereby driving the rotary switch 4 to reciprocate, that is, to realize the test of the number of rotations of the rotary switch 4. Specifically, the first fixing member 311 can fix the rotary switch 4.

[0033] Furthermore, if Figure 1 and Figure 2As shown, the first detection member 312 is a first detection rack, the second detection member 313 is a second detection rack, and the first detection assembly 31 further includes a rotating gear 41, which can be connected to the rotary switch 4. One end of the first detection rack and one end of the second detection rack are both connected to the driving unit 2, and the first detection rack and the second detection rack are respectively meshed with the two sides of the rotating gear 41, so that the rotating gear 41 can be driven to rotate by the first detection rack and the second detection rack.

[0034] In this embodiment, the first fixing member 311 includes a first adjustment seat 3111, a first clamping seat 3112, a first clamping block 3113 and a second clamping block 3114. The first adjustment structure can be adjusted on the test frame 1 along the first direction, and the first clamping seat 3112 is arranged on the first adjustment seat 3111, so that the position of the first clamping seat 3112 in the first direction can be adjusted by the first adjustment seat 3111; the first clamping block 3113 and the second clamping block 3114 are respectively arranged on both sides of the first clamping seat 3112, and the first clamping block 3113 and the second clamping block 3114 can move toward each other along the second direction, so as to clamp the rotary switch 4, and the first direction and the second direction are perpendicular. The operator can drive the first clamping block 3113 and the second clamping block 3114 to separate or approach each other by manually screwing.

[0035] The first direction is the length direction of the test frame 1 , and the second direction is the width direction of the test frame 1 .

[0036] Optionally, the first adjustment seat 3111 is a linear module.

[0037] Specifically, the second detection component 32 is configured to detect the number of switching times of the self-resetting switch 5, and the second detection component 32 includes a second fixing member 321, a third detection member 322 and a fourth detection member 323. The second fixing member 321 is arranged on the test frame 1, one end of the third detection member 322 and one end of the fourth detection member 323 are both connected to the driving unit 2 in a transmission manner, and the other end of the third detection member 322 and the other end of the fourth detection member 323 are respectively abutted against the two sides of the self-resetting switch 5. In this way, the third detection member 322 and the fourth detection member 323 can be driven by the driving unit 2 to move in the opposite direction in the vertical direction, so that the other end of the third detection member 322 abuts against one side of the self-resetting switch 5 or the other end of the fourth detection member 323 abuts against the other side of the self-resetting switch 5, so as to achieve the purpose of detecting the number of switching times of the self-resetting switch 5. The second fixing member 321 can fix the self-resetting switch 5, and the structure of the second fixing member 321 is the same as that of the first fixing member 311.

[0038] Further, the third detection member 322 includes a first connecting rod 3221 and a first abutment block 3222 connected to each other, and the fourth detection member 323 includes a second connecting rod 3231 and a second abutment block 3232 connected to each other.

In this way, the purpose of detecting the number of times the self-resetting switch 5 is switched can be achieved by abutting the first abutment block 3222 and the second abutment block 3232 against the two sides of the self-resetting switch 5, respectively.

[0039] Specifically, the third detection component 33 is configured to detect the number of times the self-locking switch 6 is switched, and the third detection component 33 includes a third fixing member 331, a fifth detection member 332, and a sixth detection member 333. The third fixing member 331 is set on the test frame 1, one end of the fifth detection member 332 and one end of the sixth detection member 333 are both connected to the driving unit 2 in a transmission manner, and the other end of the fifth detection member 332 and the other end of the sixth detection member 333 are respectively abutted against the two sides of the self-locking switch 6. In this way, the driving unit 2 can drive the fifth detection member 332 and the sixth detection member 333 to move in the opposite direction in the vertical direction, so that the other end of the fifth detection member 332 abuts against one side of the self-locking switch 6 or the other end of the sixth detection member 333 abuts against the other side of the self-locking switch 6, and the third fixing member 331 can fix the self-locking switch 6. Among them, the structure of the third fixing member 331 is the same as that of the first fixing member 311; the structure of the fifth detection member 332 is the same as that of the third detection member 322; the structure of the sixth detection member 333 is the same as that of the fourth detection member 323.

[0040] In this embodiment, the driving unit 2 includes a driving motor 21, a connecting shaft 22, a first transmission structure 23, a second transmission structure 24 and a third transmission structure 25.

[0041] Optionally, the driving unit 2 further includes a motor seat 211 , which is disposed on the test frame 1 , and the driving motor 21 is mounted on the motor seat 211 .

[0042] Further, the first transmission structure 23 includes a transmission frame 231, a transmission gear 232, a first transmission rack 233 and a second transmission rack 234. The transmission frame 231 is set on the test frame 1, the transmission gear 232 is sleeved on the connecting shaft 22, the first transmission rack 233 and the second transmission rack 234 are arranged on the transmission frame 231 at intervals, and slide with the transmission frame 231, the two sides of the transmission gear 232 are respectively meshed with the first transmission rack 233 and the second transmission rack 234, and the first transmission rack 233 and the second transmission rack 234 are both connected to the first detection component 31. With such a configuration, when the transmission gear 232 rotates, the first transmission rack 233 and the second transmission rack 234 can be respectively raised or lowered. Among them, the structures of the second transmission structure 24 and the third transmission structure 25 are the same as the structure of the first transmission structure 23.

[0043] Specifically, the control unit includes a power supply, a motor driver and a controller. The motor driver and the power supply are electrically connected to the controller, the motor driver and the drive unit 2 are electrically connected, the controller controls the drive unit 2 to work through the motor driver, and the power supply can supply power to the motor driver and the controller.

[0044] It should be noted that the control unit also includes a host computer. After the host computer successfully communicates with the controller, the number of test on-off times and on-off time are set on the host computer interface according to the test standards and design drawings, and the host computer interface is observed to see if there is any retained data. If there is data recorded, press the "recount" button to initialize the state of the controller register. Take one test end as an example to illustrate its working principle: the switch object to be tested is connected to the first pin as a feedback signal, and the input signal of the first pin is taken as a pulse signal and connected to the start end of the first timer. The normal operation of the switch will generate a pulse, interrupt the timing of the first timer and continue to work. If the first timer is not interrupted by the pulse after the timing ends, it will be judged that the current switch triggers an abnormality within the specified time, and the first alarm device will be triggered. After pressing the "start switch", activate the one-second action timer to make the drive motor move for one second, then read the path time stored in the second pin and stay for the corresponding time, reverse the direction and activate the drive motor again, the action timer makes the drive motor rotate in the opposite direction for one second and then stop, (Note: the control object of the drive motor action is not time but the number of pulses. The 1 second described here refers to the time interval reserved for the drive motor to complete the action, not the control time.) Drive the replaceable trigger head to disconnect the switch under test. Read the disconnection time and stay for a corresponding time. After the disconnection time ends, a signal is sent to represent the end of an action cycle, and the counter counts one. The third pin of the input on-off number is used as the comparison object of the counter. When the input number is reached, the signal is set to 1 to release the self-locking and the system stops running. All registers will keep the current data and wait for the operator to manually initialize the system before the next test. The three test channels of the present invention share one drive motor, so the working principles of other channels are the same as described above. When the test alarm device of any of the three test channels lights up, the self-locking is released and the system stops running.

[0045] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the embodiments here.
