[0024] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.
[0025] Please refer to Figure 1 and Figure 2 , the present application provides an embodiment of an earhook testing device 100. The earhook testing device 100 includes a driving assembly 10, a detecting assembly 20, a first bracket 30, a first fixing assembly 40, a second bracket 50, and a second fixing assembly 60. The driving assembly 10 includes a guide rail member 11 and a slider member 12. The slider member 12 is reciprocally slidably disposed along a first direction X on the guide rail member 11. The first bracket 30 is disposed on the guide rail member 11, and the first fixing assembly 40 is disposed on the first bracket 30. The second bracket 50 is disposed on the slider member 12, and the second fixing assembly 60 is disposed on the second bracket 50. The first fixing assembly 40 is used to fix a part of the test product, and the second fixing assembly 60 is used to fix a part of the test product. For example, when the test product is an earhook, the first fixing assembly 40 fixes one end of the earhook, and the second fixing assembly 60 fixes the other end of the earhook.
[0026] When the guide rail component 11 drives the slider component 12 to reciprocate along the first direction X, the slider component 12 moves synchronously with the second bracket 50, and the second bracket 50 reciprocates relative to the first bracket 30 in the first direction X. In this way, the second fixing component 60 can also reciprocate relative to the first fixing component 40 in the first direction X. The test product realizes the stretching and resetting movements with the relative movement between the first fixing component 40 and the second fixing component 60. The detection component 20 is connected to the first bracket 30 and the first fixing component 40, or the detection component 20 is connected to the second bracket 50 and the second fixing component 60. The detection component 20 is used to detect the force on the first fixing component 40 relative to the first bracket 30, or to detect the force on the second fixing component 60 relative to the second bracket 50, so as to calculate the force on the test product during the stretching process. At the same time, the detection component 20 can also record the number of stretching times of the test product, eliminating manual counting, thereby effectively improving the test efficiency and test accuracy.
[0027] The following takes the detection component 20 being arranged between the first bracket 30 and the first fixing component 40 as an example for illustration.
[0028] In some embodiments, please refer to Figure 3 and Figure 5 , the detection component 20 includes a first part 21, a second part 22 and a sensor 25. The sensor 25 is respectively connected to the first part 21 and the second part 22. Among them, the first part 21 is arranged on the first bracket 30, and the second part 22 is arranged on the first fixing component 40. During the process of the guide rail component 11 driving the slider component 12 to move along the first direction X, the test product has a pulling force on the first fixing component 40, and this pulling force is transmitted to the sensor 25 through the second part 22. In this way, the force on the test product during the stretching process can be detected, and the number of stretching times can also be recorded.
[0029] In some embodiments, please continue to refer to Figure 3, the detection component 20 further includes a first side wall 23 and a second side wall 24. The first side wall 23 is respectively connected to the first part 21 and the second part 22, and the second side wall 24 is respectively connected to the first part 21 and the second part 22. Among them, the first part 21, the second part 22, the first side wall 23 and the second side wall 24 together form a first accommodation space 26. The sensor 25 is disposed in the first accommodation space 26, and the sensor 25 is respectively connected to the first side wall 23 and the second side wall 24. The force of the test product on the first fixing component 40 drives the second part 22 to move relative to the first part 21. At this time, the first side wall 23 and the second side wall 24 are deformed. Since the sensor 25 is respectively connected to the first side wall 23 and the second side wall 24, the deformation of the first side wall 23 and the second side wall 24 causes a change in the resistance of the sensor 25. When a constant voltage is applied to the sensor 25, the change in the current passing through the sensor 25 can be calculated. According to the preset mapping relationship between the current and the tensile force, the value of the tensile force can be calculated, so as to obtain the tensile force received by the test product during stretching. According to the tensile force obtained from each movement, the number of stretches of the test product can be obtained. For example, the cumulative number of stretches when the earhook is finally pulled off can be obtained, that is, the stretching life of the earhook.
[0030] In some embodiments, please refer to Figure 3 , the first part 21 is provided with a first hook portion 211, the second part 22 is provided with a second hook portion 221, and the first hook portion 211 and the second hook portion 221 are nested with each other and are spaced apart in the initial state. By respectively providing the first hook portion 211 and the second hook portion 221 on the first part 21 and the second part 22 for nested connection, it is possible to prevent the first part 21 and the second part 22 from being separated from each other due to excessive force in the first direction X, causing the sensor 25 to be torn and damaged. The first hook portion 211 and the second hook portion 221 are spaced apart, so that within the preset safe tensile force range, the first part 21 and the second part 22 can move relative to each other, so that the first side wall 23 and the second side wall 24 are deformed.
[0031] The detection component 20 can be disposed between the first bracket 30 and the first fixing component 40, or can be disposed between the second bracket 50 and the second fixing component 60. As an example, the first part 21 is disposed on the second bracket 50, the second part 22 is disposed on the second fixing component 60, and the sensor 25 is disposed between the first part 21 and the second part 22. The tensile force of the test product on the second fixing component 60 causes the first part 21 and the second part 22 to move relative to each other, so that the sensor 25 can detect the relative acting force between the first part 21 and the second part 22. It should be noted that the detection component 20 can be provided between the first bracket 30 and the first fixing component 40 and between the second bracket 50 and the second fixing component 60 at the same time, or only one side can be provided with the detection component 20.
[0032] In some embodiments, refer to Figure 4 and Figure 5 , the first fixing component 40 includes a first mounting base 41 and a first hook member 42. When there is a detection component 20 between the first bracket 30 and the first fixing component 40, the first mounting base 41 is connected to the second part 22. When there is no detection component 20 between the first bracket 30 and the first fixing component 40, the first mounting base 41 is directly connected to the first bracket 30. The first hook member 42 is disposed on a side of the first mounting base 41 facing away from the first bracket 30. A second receiving space 43 is formed between the first hook member 42 and the first mounting base 41, and the first hook member 42 is configured to fix a part of the test product in the second receiving space 43.
[0033] As an embodiment, the first hook member 42 includes a first support column 421, a second support column 422, a first rotating member 423, and a first fixing member 424. The first support column 421 has a first end and a second end disposed opposite to each other, wherein the first end of the first support column 421 is fixed to the first mounting base 41, and the first rotating member 423 is rotatably disposed at the second end of the first support column 421. The second support column 422 has a first end and a second end disposed opposite to each other, wherein the first end of the second support column 422 is fixed to the first mounting base 41, and the first fixing member 424 is disposed at the second end of the second support column 422. The first rotating member 423 can be rotated to open or close the second receiving space 43, and when the first rotating member 423 rotates to be connected to the second support column 422, the first fixing member 424 fixes the first rotating member 423 relative to the second support column 422, thereby fixing a part of the test product in the second receiving space 43.
[0034] As an example, the first fixing member 424 is screwed to the second end of the second support column 422, and the first rotating member 423 is provided with a first notch 4231. When the first rotating member 423 rotates to be connected to the second support column 422 or the first fixing member 424, a part of the second support column 422 or a part of the first fixing member 424 is located in the first notch 4231. By rotating the first fixing member 424, the first rotating member 423 is clamped between the first fixing member 424 and the second support column 422, so that the first rotating member 423 can be fixed to the second support column 422.
[0035] In some embodiments, refer to Figure 6, the second fixing component 60 includes a second mounting base 61 and a second hook member 62. When there is a detection component 20 between the second bracket 50 and the second fixing component 60, the second mounting base 61 is connected to the second part 22. When there is no detection component 20 between the second bracket 50 and the second fixing component 60, the second mounting base 61 is directly connected to the second bracket 50. The second hook member 62 is disposed on a side of the second mounting base 61 away from the second bracket 50. A third receiving space 63 is formed between the second hook member 62 and the second mounting base 61, and the second hook member 62 is used to fix a part of the test product in the third receiving space 63.
[0036] As an embodiment, the second hook member 62 includes a third support column 621, a fourth support column 622, a second rotating member 623, and a second fixing member 624. The third support column 621 has a first end and a second end disposed opposite to each other, wherein the first end of the third support column 621 is fixed to the second mounting base 61, and the second rotating member 623 is rotatably disposed at the second end of the third support column 621. The fourth support column 622 has a first end and a second end disposed opposite to each other, wherein the first end of the fourth support column 622 is fixed to the second mounting base 61, and the second fixing member 624 is disposed at the second end of the fourth support column 622. The second rotating member 623 can be rotated to open or close the third receiving space 63, and when the second rotating member 623 rotates to be connected to the fourth support column 622, the second fixing member 624 fixes the second rotating member 623 relative to the fourth support column 622, thereby fixing a part of the test product in the third receiving space 63.
[0037] As an example, the second fixing member 624 is screwed to the second end of the fourth support column 622. The second rotating member 623 is provided with a second notch 6231. When the second rotating member 623 rotates to be connected to the fourth support column 622 or the second fixing member 624, a part of the fourth support column 622 or a part of the second fixing member 624 is located in the second notch 6231. By rotating the second fixing member 624, the second rotating member 623 is clamped between the second fixing member 624 and the fourth support column 622, so that the second rotating member 623 can be fixed to the fourth support column 622.
