AI Technical Summary
The existing analog plug-in and unplugging structure cannot accurately simulate the deflected plug-in and unplugging force of the external data connector and the USB data interface of the conference machine, resulting in inaccurate test results.
A simulation and testing mechanism for external data interface of conference machines is designed, using multiple electric push rods and connecting rod structures to simulate the deflection plug-and-pull force of external data joints in actual use. Through the synergistic action of electric push rods, a deflection plug-and-pull force test is achieved in four directions.
It improves the accuracy of the test results and can more realistically simulate the skew plug-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull-and-pull

Description
Technical Field
[0001] The utility model belongs to the technical field of conference machine testing, and particularly relates to a simulation test mechanism for an external data interface of a conference machine. Background Art
[0002] An intelligent conference machine, also called an intelligent conference tablet or an intelligent conference touch all-in-one machine, mainly meets the communication and display requirements for commercial office, conference occasions, and leisure discussion areas. When performing plug and unplug service life tests on the frequently plugged and unplugged external data interfaces of the conference machine, such as USB data interfaces, the plugging and unplugging force direction of the external data connector of the existing simulation plugging and unplugging structure is consistent with the center line of the USB data interface of the conference machine. However, in actual use of the USB data interface, the plugging and unplugging force direction of the external data connector is basically skewed. This results in inaccurate test results when the existing simulation plugging and unplugging structure conducts plug and unplug service life tests on the USB data interface of the conference machine. Summary of the Invention
[0003] The technical problem to be solved by the utility model is to provide a mechanism for simulating the test of the skewed plugging and unplugging force between the external data connector and the USB data interface of the conference machine in actual use.
[0004] To solve the above technical problem, the present invention is realized through the following technical solutions: A simulation test mechanism for an external data interface of a conference machine includes a test base, a carrier table, a cylindrical sleeve, a bearing plate, a push plate, a cylindrical guiding block, a connecting rod, a guiding sleeve, a first electric push rod, a second electric push rod, a third electric push rod, and a control module. The carrier table is fixedly installed at the bottom of the test base. The cylindrical sleeve and the guiding sleeve are coaxially and fixedly installed on the top plate of the test base. The push plate and the cylindrical guiding block are respectively fixedly installed at the upper and lower ends of the connecting rod. The cylindrical guiding block can be placed in the guiding sleeve in a sliding clearance fit manner. A stop ring for restricting the downward movement position of the bearing plate is fixedly installed on the inner wall of the guiding sleeve. Four first electric push rods are fixedly installed on the top plate of the test base in a circular distribution. The bearing plate is fixedly installed on... Four second electric push rods are fixedly installed at the edge positions of the bearing plate in a circular distribution. One third electric push rod is fixedly installed at the center position of the bearing plate. The top ends of the actuating rods of the first electric push rod, the second electric push rod, and the third electric push rod are respectively fixedly installed with a first disc, a second disc, and a third disc. The first electric push rod, the second electric push rod, and the third electric push rod are respectively connected to the control module through circuits.
[0005] Preferably, the edge of the top surface of the cylindrical guiding block is provided with a rounded corner structure.
[0006] Preferably, the bottom of the guiding sleeve is integrally formed and coaxially provided with a frustum sleeve structure.
[0007] Preferably, it further includes a support sleeve and a telescopic rod. A plurality of pin holes are arranged in a longitudinal linear array on the support sleeve and the telescopic rod in a matching manner. The support sleeve is fixedly installed at the bottom of the test seat. The top end of the telescopic rod is fixedly installed at the bottom of the stage. The lower end of the telescopic rod is slidably installed in the support sleeve. A positioning pin is inserted into the pin holes where the support sleeve and the telescopic rod are matched.
[0008] Preferably, limiting rods are fixedly installed on the inner walls of both sides of the cylindrical sleeve. Spherical limiting grooves are arranged on both sides of the push pressure plate. The outer ends of the limiting rods are arranged as spherical convex structures that match the spherical limiting grooves.
[0009] Compared with the prior art, the beneficial effects of the present utility model are as follows: Since the first electric push rod and the second electric push rod are both arranged at non-central positions of the connecting rod in this mechanism, the thrust directions of the actuating rods of the first electric push rod and the second electric push rod when extended do not coincide with the center line of the USB data interface of the conference machine. Therefore, it can simulate the use requirements of the external data connector and the USB data interface of the conference machine for the use of oblique insertion and extraction force testing in actual use, thereby improving the accuracy of the test results.

[0013] The present utility model will be described in detail below in conjunction with the specific embodiments:
[0014] Such as Figure 1 and Figure 2A simulation test mechanism for an external data interface of a conference machine as shown in the figure, comprising a test socket 1, a carrier 2, a cylindrical sleeve 3, a bearing plate 4, a push plate 41, a cylindrical alignment block 42, a connecting rod 43, an alignment sleeve 5, a first electric push rod 6, a second electric push rod 7, a third electric push rod 8 and a control module. The carrier 2 is fixedly installed at the bottom of the test socket 1. The cylindrical sleeve 3 and the alignment sleeve 5 are coaxially and fixedly installed on the top plate of the test socket 1. The push plate 41 and the cylindrical alignment block 42 are respectively fixedly installed at the upper and lower ends of the connecting rod 43. The cylindrical alignment block 42 can be placed in the alignment sleeve 5 in a sliding clearance fit manner. A stop ring 31 for restricting the downward movement position of the bearing plate 4 is fixedly installed on the inner wall of the alignment sleeve 5. Four first electric push rods 6 are fixedly installed on the top plate of the test socket 1 in a circular distribution. The bearing plate 4 is fixedly installed. Four second electric push rods 7 are fixedly installed at the edge positions of the bearing plate 4 in a circular distribution. One third electric push rod 8 is fixedly installed at the center position of the bearing plate 4. The top ends of the actuating rods of the first electric push rod 6, the second electric push rod 7 and the third electric push rod 8 are respectively fixedly installed with a first disc 61, a second disc 71 and a third disc. The first electric push rod 6, the second electric push rod 7 and the third electric push rod 8 are respectively connected to the control module through circuits.
[0015] The top edge of the cylindrical alignment block 42 is set as a rounded structure. The top of the cylindrical alignment block 42 slides and is embedded in the alignment sleeve 5. The rounded structure can play a guiding role and avoid the problem of interference and collision between the top of the cylindrical alignment block 42 and the bottom of the alignment sleeve 5.
[0016] The bottom of the alignment sleeve 5 is integrally formed and coaxially provided with a frustum sleeve structure. The top of the cylindrical alignment block 42 slides and is embedded in the alignment sleeve 5. The frustum sleeve structure can play a guiding role and avoid the problem of interference and collision between the top of the cylindrical alignment block 42 and the bottom of the alignment sleeve 5.
[0017] It further includes a support sleeve 21 and a telescopic rod 22. A plurality of pin holes are arranged in a longitudinal linear array on the support sleeve 21 and the telescopic rod 22 in a matching manner. The support sleeve 21 is fixedly installed at the bottom of the test socket 1. The top end of the telescopic rod 22 is fixedly installed at the bottom of the carrier 2. The lower end of the telescopic rod 22 is slidably installed in the support sleeve 21. A positioning pin is inserted into the pin holes where the support sleeve 21 and the telescopic rod 22 are matched. By pulling out the positioning pin, the relative installation position of the telescopic rod 22 and the support sleeve 21 can be adjusted, and thus the installation height of the carrier 2 can be adjusted to meet the actual use requirements.
[0018] On both inner walls of the cylinder sleeve 3, a limiting rod 9 is fixedly installed. On both sides of the push plate 41, spherical limiting grooves are provided. The outer end of the limiting rod 9 is provided with a spherical convex structure that matches the spherical limiting grooves. The spherical convex structure at the outer end of the limiting rod 9 is embedded in the spherical limiting grooves on both sides of the push plate 41, which can form a limiting effect to prevent the combination of the push plate 41, the cylindrical alignment block 42, and the connecting rod 43 from falling downward under its own gravity.
[0019] On the carrier 2, a fixture is fixedly installed, and the conference machine to be detected is fixedly installed on the fixture for the plugging and unplugging service life test of the USB data interface. The test external data connector 10 is clamped and fixed in the mounting hole at the bottom of the cylindrical alignment block 42. When the actuator rod of any one of the first electric push rods 6 extends, the first disc 61 pushes the combination of the push plate 41, the cylindrical alignment block 42, the connecting rod 43, and the test external data connector 10 upward, so that the test external data connector 10 is pulled out from the USB data interface of the conference machine. The cylindrical alignment block 42 is positioned in the alignment sleeve 5 in a sliding clearance fit manner. After being limited by the limiting rod 9, the actuator rod of the first electric push rod 6 retracts and resets. The control module starts the actuator rod of the third electric push rod 8 to extend again, and pushes the combination of the push plate 41, the cylindrical alignment block 42, and the connecting rod 43 downward through the third disc. After the test external data connector 10 is inserted into contact with the USB data interface by 2-3 mm, the actuator rod of the third electric push rod retracts and resets. The cylindrical alignment block 42 disengages from the cylindrical section of the alignment sleeve 5 and enters the frustum sleeve structure. The control module controls the actuator rod of any one of the second electric push rods 7 to extend, and pushes the combination of the push plate 41, the cylindrical alignment block 42, the connecting rod 43, and the test external data connector 10 downward through the second disc 71, so that the test external data connector 10 is inserted into the USB data interface of the conference machine. Each time a plugging and unplugging test is performed, one of the four first electric push rods 6 is started in sequence, and one of the four second electric push rods 7 is started in sequence, which can meet the requirements for the use of the plugging and unplugging forces in four directions with deflection.
