[0002] In modern industrial production, the service life of various mechanical equipment is an important performance indicator, which directly affects the reliability of the equipment and the maintenance cost. Among them, as a common mechanical component, the opening and closing life of the handle is very important. Traditional handle life tests usually require manual operation, which is not only time-consuming and laborious, but also difficult to ensure the accuracy and repeatability of the test results.

[0043] Please refer to Figures 1 - 4 , this embodiment provides a handle opening and closing test device 100. The handle opening and closing test device 100 includes a workbench 110, a mounting seat 120, a handle pressing unit 130, and a non-contact detection unit 140;

[0044] The mounting seat 120, the handle pressing unit 130, and the non-contact detection unit 140 are all connected to the workbench 110; the mounting seat 120 is used for mounting the handle 10 to be tested; the handle pressing unit 130 is used for pressing or releasing the handle 11 of the handle 10 to be tested; the non-contact detection unit 140 is used for detecting the opening and closing state of the handle 11 or the opening and closing state of the clamping head 13 of the handle 10 to be tested.

[0045] Please refer to Figures 1 - 4 , the working principle of the handle opening and closing test device 100 is:

[0046] First, the handle opening and closing test device 100 includes a workbench 110, a mounting base 120, a handle pressing unit 130, and a non-contact detection unit 140;

[0047] Among them, the mounting base 120 is used to mount the handle 10 to be tested; the handle pressing unit 130 is used to press or release the handle 11 of the handle 10 to be tested; the non-contact detection unit 140 is used to detect the opening and closing state of the handle 11 or the opening and closing state of the jaw 13 of the handle 10 to be tested;

[0048] Thus, during the process of testing the handle 10 using the handle opening and closing test device 100, the handle pressing unit 130 can press the handle 11 of the handle 10 to be tested according to the test requirements; moreover, during the process of testing the handle 10, the non-contact detection unit 140 can detect the opening and closing state of the handle 11 or the opening and closing state of the jaw 13 of the handle 10 to be tested. Since the non-contact detection unit 140 does not need to contact the handle 10 to be tested during the detection process, it can avoid wear of the non-contact detection unit 140 during the test, thereby avoiding a decrease in the detection accuracy of the non-contact detection unit 140 as the detection continues, and thus improving the accuracy of the detection results;

[0049] It should be noted that during the testing process of the handle opening and closing test device 100, it can achieve automated testing based on its control system. That is, it can control the handle pressing unit 130 and the non-contact detection unit 140 through the control system, and then control the handle pressing unit 130 to press the handle 11 of the handle 10 to be tested at a predetermined frequency. At the same time, it can collect the relevant data detected by the non-contact detection unit 140 for the purpose of sorting and analyzing the detected data; in addition, the aforementioned control system is a prior art, so it will not be elaborated here;

[0050] On this basis, through the above structural settings, it can achieve fully automated detection and data collection, and thus reduce manual intervention during the test process, which not only increases the complexity of the test but also reduces the test efficiency;

[0051] In summary, the handle opening and closing test device 100 can improve the test efficiency of the handle 10, reduce the workload that requires manual intervention during the test process, and improve the accuracy of the test results; moreover, during the test process, based on the above structural settings, the handle opening and closing test device 100 can not only collect the test times of the handle 10 but also detail and record the specific situation of each test of the detected handle 10 for the purpose of analyzing the handle 10, thereby clarifying the life law of the handle 10 for the purpose of improving the design of the handle 10.

[0052] It should be noted that when configuring the mounting base 120, its function is to mount the handle 10 to be tested. When mounting the handle 10, to improve the mounting efficiency and the mounting stability, the mounting base 120 includes a bottom platform 121, a first positioning seat 122, and a second positioning seat 123. Among them, both the first positioning seat 122 and the second positioning seat 123 are connected to the bottom platform 121, and the first positioning seat 122 and the second positioning seat 123 jointly form and assemble the cavity for the handle 10. In addition, when setting the first positioning seat 122 and the second positioning seat 123, the first positioning seat 122 can be fixedly connected to the bottom platform 121, and the second positioning seat 123 is magnetically connected to the first positioning seat, so as to improve the assembly efficiency in this way.

[0053] Please refer to Figure 4 , Figure 4 shows the structure of the handle opening and closing test system 200 adopting the handle opening and closing test device 100. The handle opening and closing test system 200 includes a test box frame 210, and the handle opening and closing test device 100 is arranged in the test box frame 210, aiming to form an independent test space and play a protective role for the handle opening and closing test device 100 and the handle 10 being tested.

[0054] Furthermore, please refer to Figures 1 - 6 , in this embodiment, the non-contact detection unit 140 includes a movable detection frame 141, a connecting clip 142, and a non-contact detector 143;

[0055] The movable detection frame 141 is connected to the workbench 110; the connecting clip 142 is connected to the free end of the movable detection frame 141 and is used to connect the non-contact detector 143;

[0056] The non-contact detector 143 is used to detect the opening and closing state of the handle 11 or the opening and closing state of the jaw 13 of the handle 10 to be tested.

[0057] Among them, through the setting of the movable detection frame 141, the spatial position of the connecting clip 142 connected to the free end of the movable detection frame 141 can be adjusted, so that the spatial position of the non-contact detector 143 can be adjusted. In this way, the position of the non-contact detector 143 can be adjusted to meet the detection requirements of handles 10 with different size specifications.

[0058] Specifically, when configuring the activity detection frame 141, it may at least include a first link 144 and a second link 145. The first link 144 is movably connected to the workbench 110, and the second link 145 is rotatably connected to the first link 144. The connecting clip 142 is rotatably connected to the second link 145. Moreover, the rotation axis of the connecting clip 142 relative to the second link 145, the rotation axis of the second link 145 relative to the first link 144, and the rotation axis of the first connecting rod relative to the workbench 110 are arranged at an angle, and can also be perpendicular to each other in pairs. The purpose is to be able to adjust the position of the connecting clip 142 and the non-contact detector 143 connected to the connecting clip 142 in space, so that it has multiple degrees of freedom.

[0059] In addition, in this embodiment, during the detection process, in order to detect the opening and closing of the handle 11 of the handle 10 and the opening and closing of its clamping head 13, therefore, the handle opening and closing test device 100 includes two non-contact detection units 140. The two non-contact detection units 140 are respectively used to detect the opening and closing state of the handle 11 and the opening and closing state of the clamping head 13 of the handle 10 to be tested. It should be noted that during the detection process, when the handle 11 is in the pressed state, the non-contact detector 143 is used to detect the opening and closing of the handle 11 of the handle 10 and the opening and closing of its clamping head 13, and the qualified state of the handle 10 can be determined. That is, when the handle pressing unit 130 is in the position of pressing the handle 11, if one or both of the handle 11 and its clamping head 13 are not in the closed state, it can be determined that it is unqualified; similarly, when the handle pressing unit 130 is in the position of releasing the handle 11, if one or both of the handle 11 and its clamping head 13 are in the closed state, it can be determined that it is unqualified;

[0060] On the contrary, when the handle pressing unit 130 is in the position of pressing the handle 11, if one or both of the handle 11 and its clamping head 13 are in the closed state, it can be determined that it is qualified; similarly, when the handle pressing unit 130 is in the position of releasing the handle 11, if one or both of the handle 11 and its clamping head 13 are in the open state, it can be determined that it is qualified.

[0061] Moreover, in this embodiment, based on the above content, when configuring the non-contact detection unit 140, it may include an optical fiber sensor. By setting it in this way, non-contact detection of the handle 10 can be achieved. Specifically, during the detection process, it is necessary to first adjust the position of the optical fiber sensor in advance according to the usage requirements so that the emitted detection light is directed at the jaw 13 or the handle 11. During the detection process, as the handle pressing unit 130 operates and presses the handle 11, the jaw 13 and the handle 11 move, which causes the original detection light to be unblocked or reflected, thereby changing the state of the light received by the optical fiber sensor. As a result, the optical fiber sensor can detect the movements of the jaw 13 and the handle 11, thus achieving non-contact detection.

[0062] Further, please refer to Figures 1 - 10 , in this embodiment, when configuring the handle pressing unit 130, the handle pressing unit 130 may include a first driving member 131, a second driving member 132, a first pressing member 133, and a second pressing member 134. Both the first driving member 131 and the second driving member 132 are connected to the workbench 110. It should be noted that in this embodiment, an unlocking switch 12 is provided at the handle 11 of the to-be-tested handle 10. When it is pressed, the unlocking switch 12 will be locked and its reset will be restricted, that is, the unlocking switch 12 will keep the vehicle in the pressed position. Only when the unlocking switch 12 is released and unlocked, the handle 11 will reset.

[0063] Among them, the first driving member 131 is used to drive the first pressing member 133 to move in the direction close to the handle 11 to press the handle 11, or move in the direction away from the handle 11 to release the pressed handle 11. The second driving member 132 is used to drive the second pressing member 134 to move in the direction close to the handle 11 to press the unlocking switch 12 on the handle 11, or move in the direction away from the handle 11 to release the pressed unlocking switch 12.

[0064] Thus, during the detection process, taking one detection cycle action as an example, its steps include:

[0065] The first driving member 131 drives the first pressing member 133 to move in the direction close to the handle 11 to press the handle 11.

[0066] Subsequently, the non-contact detector 143 is used to detect the opening and closing state of the handle 11 or the opening and closing state of the jaw 13 of the to-be-tested handle 10.

[0067] After determining that the handle 10 is in a qualified state at this time, the second driving member 132 drives the second pressing member 134 to move in the direction close to the handle 11 to press the unlocking switch 12 on the handle 11 to unlock it, and then moves in the direction away from the handle 11 to release the pressed unlocking switch 12.

[0068] After the first driving member 131 drives the first pressing member 133 to move away from the handle 11 to release the handle 11, if the handle 11 and the clamping head 13 are reset, and it is determined that the handle 10 is in a qualified state according to the detection result of the non-contact detector 143, then the single detection ends;

[0069] It should be noted that in the above steps, if it is determined that the handle 10 is in an unqualified state according to the detection result of the non-contact detector 143, the detection data can be output to facilitate the collection and recording of the corresponding detection data, so that the handle opening and closing test device 100 can not only collect the number of test times of the handle 10, but also detail and record the specific situation of each test of the detected handle 10, so as to facilitate the analysis of the handle 10, so as to clarify the life law of the handle 10, so as to facilitate the improvement design of the handle 10.

[0070] When configuring the first driving member 131, the first driving member 131 includes a first mounting frame 135, a rotating lead screw 136, a driving motor 137 and a movable slider 138; the first mounting frame 135 is connected to the workbench 110, the rotating lead screw 136 is rotatably connected to the first mounting frame 135, the driving motor 137 is connected to the first mounting frame 135 and is in transmission connection with the rotating lead screw 136;

[0071] The movable slider 138 is slidably connected to the first mounting frame 135 along the axial direction of the rotating lead screw 136 and is threadedly connected to the rotating lead screw 136; the first pressing member 133 is connected to the movable slider 138.

[0072] That is, through the setting of the above structure, the operation of the driving motor 137 can drive the movable slider 138 to reciprocate, thereby driving the first pressing member 133 to reciprocate to meet the above detection requirements.

[0073] In addition, based on the above rotating lead screw 136, the movement stroke of the first pressing member 133 can be accurately controlled, and in order to limit the movement of the first pressing member 133 to prevent it from damaging the handle 11 and enabling it to reciprocate within a suitable stroke to improve its detection efficiency, therefore, the handle pressing unit 130 further includes at least two limit blocks 139; the two limit blocks 139 are both connected to the first mounting frame 135 and are arranged at intervals along the axial direction of the rotating lead screw 136, and the limit blocks 139 are used to abut against the first pressing member 133 to limit the movement of the first pressing member 133 in the direction close to the handle 11 or in the direction away from the handle 11.

[0074] When configuring the second driving member 132, the second driving member 132 includes a second mounting bracket 151 and a driving cylinder block 152. The driving cylinder block 152 is connected to the second mounting bracket 151, and the second pressing member 134 is connected to the piston rod of the driving cylinder block 152. In this embodiment, the driving cylinder block 152 is a cylinder or an oil cylinder to drive the second pressing member 134 to move.

[0075] In addition, when configuring the first pressing member 133 and the second pressing member 134, the first pressing member 133 includes an L-shaped pressing rod 153 and a pressing roller 154. One end of the L-shaped pressing rod 153 is connected to the movable slider 138, and the pressing roller 154 is rotatably connected to the other end of the L-shaped pressing rod 153; the second pressing member 134 includes a strip-shaped pressing rod 155; wherein, the L-shaped pressing rod 153 is provided with a through hole 156 for the strip-shaped pressing rod 155 to pass through.

[0076] Thus, through the above settings of the first pressing member 133 and the second pressing member 134, it is possible to avoid movement interference between the first pressing member 133 and the second pressing member 134 during the detection process, thereby improving the detection efficiency.

[0077] In the above content, it should also be noted that during the detection process, the operation state of the second driving member 132 can be selectively controlled according to the structure of the handle 10.

[0078] And since the handle 10 selected in this embodiment is configured with a clamp head 13, therefore, to position its installation position and prevent the position of the clamp head 13 from changing during the detection process, the handle opening and closing test device 100 further includes a clamp rod fixing frame 160 connected to the workbench 110, and the clamp rod fixing frame 160 is used to clamp the clamp rod 14 of the handle 10 to be tested.
