[0020] As Figures 1 to 2 shown, in this embodiment, the present utility model includes a main body module 1, a flip cover module 2, a magnetic connector module 3 and a test module 4. The magnetic connector module 3 and the test module 4 are fixedly matched on the main body module 1. The flip cover module 2 includes a flip cover mounting seat 20, a rotating shaft 21, a large flip cover 22 and a small flip cover 23. The flip cover mounting seat 20 is fixed on one side of the main body module 1. The large flip cover 22 and the small flip cover 23 are both rotationally matched with the flip cover mounting seat 20 through the rotating shaft 21. The lower surface of the large flip cover 22 is connected and matched with the small flip cover 23. A pin module 5 connected and matched with the magnetic connector module 3 is arranged on the small flip cover 23. Thus, it can be seen that the magnetic connector module 3 and the test module 4 are arranged on the main body module 1 of the present utility model. At the same time, the flip cover module 2 is divided into a large flip cover 22 and a small flip cover 23. The large flip cover 22 plays a role in supporting and protecting the small flip cover 23. The pin module 5 is arranged on the small flip cover 23. The flip cover module 2 rotates and presses the test module 4 through the rotating shaft 21, and also drives the pin module 5 to contact the magnetic connector module 3 and the test module 4 on the main body module 1, and transmits the test signal obtained by the test module 4 to an external device through the pin module 5.
[0021] As Figures 2 to 5 shown, in this embodiment, the test module 4 is fixedly matched on the main body module 1 through a pin 10. The test module 4 includes a motor under test 40 and a lead screw 41. The movable end of the motor under test 40 is connected to the lead screw 41. A moving block 410 in transmission cooperation is arranged on the lead screw 41. Thus, it can be seen that the test module 4 drives the moving block 410 to move through the lead screw 41 to perform acoustic and mechanical tests on the motor under test 40.
[0022] As Figures 3 to 4As shown in the figure, in this embodiment, guide sleeves 11 are provided on both sides of the main body module 1. The guide sleeves 11 are in limit cooperation with external devices. Magnets 12 are provided at the four top corners of the upper surface of the main body module 1. The magnets 12 are in adsorption cooperation with the external devices. Thus, it can be seen that the guide sleeves 11 play a role of positioning and limiting when the main body module 1 is connected to the external device. The four top corners of the main body module 1 are provided with the magnets 12, which strengthens the contact with the external device.
[0023] As Figures 3 to 4 shown in the figure, in this embodiment, a groove and a through beveled rectangular hole 13 are provided on the lower surface of the main body module 1. A circuit board 14 is provided on the groove. The circuit board 14 is connected to the magnetic connector module 3. Thus, it can be seen that the groove is provided on the lower surface of the main body module 1 to be able to install the circuit board 14, which plays a role in aesthetic and lightweight design. The main body module 1 is provided with a through beveled rectangular hole 13, which can reduce the resonance effect generated between the motor under test 40 and the main body module 1 during the test, improve the test effect, and reduce the retest rate.
[0024] As Figure 4 shown in the figure, in this embodiment, a plurality of cylindrical blocks 15 are provided on one side of the main body module 1 close to the flip cover mounting seat 20. The cylindrical blocks 15 are in connection cooperation with the flip cover mounting seat 20. Thus, it can be seen that the cylindrical blocks 15 play a role of positioning and guiding during the contact process between the flip cover mounting seat 20 and the main body module 1.
[0025] As Figures 6 to 7 shown in the figure, in this embodiment, a plurality of torsion springs 210 that are rotationally matched with the rotating shaft 21 are provided on the rotating shaft 21. A plurality of mounting holes that are in limit cooperation with the torsion springs 210 are provided on the flip cover mounting seat 20 and the large flip cover 22. Thus, it can be seen that a plurality of the torsion springs 210 are stuck in the mounting holes of the flip cover mounting seat 20 and the large flip cover 22, and by releasing the torsion springs 210, the flip cover module 2 can be quickly rotated, saving operation time.
[0026] As Figures 6 to 7As shown in the figure, in this embodiment, the needle body module 5 includes an overpressure prevention mounting plate 50, a needle body mounting plate 51, a first needle body component 52 and a second needle body component 53. The first needle body component 52 and the second needle body component 53 are both arranged on the small flip cover 23. The second needle body component 53 is connected and cooperated with the magnetic connector module 3. The lower surface of the small flip cover 23 is fixedly cooperated with the overpressure prevention mounting plate 50. The lower surface of the overpressure prevention mounting plate 50 is fixedly cooperated with the needle body mounting plate 51. The lower surface of the needle body mounting plate 51 is fixedly cooperated with the first needle body component 52. The first needle body component 52 is in contact and cooperation with the test module 4. Thus, it can be seen that the needle body module 5 is arranged on the lower surface of the small flip cover 23. During the flipping process of the small flip cover 23, the first needle body component 52 gradually contacts the test module 4, and the second needle body component 53 gradually contacts the magnetic connector module 3. When the test module 4 conducts a test, the tested information is transmitted to the second needle body component 53 through the first needle body component 52, and then the second needle body component 53 transmits it to the magnetic connector module 3 on the main body module 1, and the magnetic connector module 3 transmits it to an external device.
[0027] As Figures 2 to 5 shown, in this embodiment, the main body module 1 further includes a motor fixing seat 16 and a buckle 17. The motor under test 40 is fixedly cooperated with the motor fixing seat 16. The buckle 17 is hingedly cooperated on one side of the main body module 1 away from the rotating shaft 21. Thus, it can be seen that the motor under test 40 is fixed on the main body module 1 through the motor fixing seat 16, and the buckle 17 is arranged on the main body module 1 to limit the flip cover module 2.
[0028] As Figures 6 to 7 shown, in this embodiment, the large flip cover 22 is provided with a convex block 220, a pair of ball bearings 221, a pair of linear bearing limit blocks 222 and a plurality of pressing rods 223. A pair of the ball bearings 221 are respectively connected to both sides of the small flip cover 23. A pair of the linear bearing limit blocks 222 are respectively arranged on both sides of the large flip cover 22. The ball bearings 221 are in sliding cooperation with the linear bearing limit blocks 222. The pressing rods 223 are in limit cooperation with the motor fixing seat 16. The convex block 220 is in limit cooperation with the buckle 17. Thus, it can be seen that the convex block 220 is in limit cooperation with the buckle 17 to achieve the effect of locking the flip cover module 2 from moving. During the rotation of the large flip cover 22 due to the rotating shaft 21, the ball bearings 221 are in sliding cooperation under the guiding action of the ball bearing limit blocks 222, and the pressing rods 223 also move along with the large flip cover 22 and gradually approach the motor fixing seat 16. Finally, because the convex block 220 is in limit cooperation, the pressing rods 223 are also in limit cooperation with the motor fixing seat 16.
[0029] In this embodiment, the working principle of the present utility model is as follows:
[0030] As Figures 1 to 7 shown, when a micro motor needs to be functionally tested, the buckle 17 is toggled, and the flip cover module 2 rotates under the action of the rotating shaft 21 and the torsion spring 210. Subsequently, the micro motor is fixed on the motor fixing seat 16, a load is added to the moving block 410, and then the flip cover module 2 is rotated in the reverse direction of opening. The needle body module 5 on the small flip cover 23 is first connected and matched with the magnetic connector module 3, and the large flip cover 22 also rotates and presses down. The buckle 17 on the large flip cover 22 buckles the convex block 220, and then acoustic testing and mechanical testing are carried out on the micro motor. The circuit board 14 on the main body module 1 transmits the test information to an external device for analysis and processing, and finally completes the testing of the micro motor product.
[0031] Although the embodiments of the present utility model are described with actual solutions, they do not constitute a limitation to the meaning of the present utility model. For those skilled in the art, modifications to its implementation solutions according to this specification and combinations with other solutions are obvious.
