[0023] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.

[0024] This utility model provides a student experimental examination terminal 100. Please refer to [link / reference]. Figure 1 and Figure 2 , Figure 1 This is a three-dimensional structural diagram of a student experimental examination terminal 100 according to one embodiment of the present utility model; Figure 2 yes Figure 1A schematic diagram of the student experimental examination terminal 100 from another perspective. The student experimental examination terminal 100 includes a display module 10, a first camera module 20, and a second camera module 30. The first camera module 20 includes a first swing arm 21, a first telescopic swing arm 22, and a first camera module 23. The first telescopic swing arm 22 is connected to the display module 10 and is slidably connected to the first swing arm 21. The first camera module 23 is connected to the first telescopic swing arm 22. When the first telescopic swing arm 22 slides relative to the first swing arm 21, it can drive the first camera module 23 to move in a direction closer to or away from the display module 10. The second camera module 30 includes a second swing arm 31, a second telescopic swing arm 32, and a second camera module 33. The second telescopic swing arm 32 is connected to the display module 10 and is slidably connected to the second swing arm 31. The second camera module 33 is connected to the second telescopic swing arm 32. When the second telescopic swing arm 32 slides relative to the second swing arm 31, it can drive the second camera module 33 to move in a direction closer to or away from the display module 10.

[0025] Specifically, the first swing arm 21 is connected to the display module 10 from one side along the Y direction, and the second swing arm 31 is connected to the display module 10 from one side along the X direction. When the first telescopic swing arm 22 slides relative to the first swing arm 21, the first camera module 23 can move relative to the display module 10 from one side along the Z direction. When the second telescopic swing arm 32 slides relative to the second swing arm 31, it can drive the second camera module 33 to move closer to or further away from the display module 10 along the Z direction.

[0026] It is understandable that the first swing arm 21 and the second swing arm 31 are connected to the display module 10 from both sides, which helps to stagger the first camera module 23 and the second camera module 33, thereby increasing the monitoring field of view.

[0027] The student experimental examination terminal 100 of this utility model has two advantages. First, it is equipped with a first camera module 23 and a second camera module 33, which helps to increase the monitoring field of view and reduce the risk that experimental equipment may be outside the monitoring field of view during the experimental examination, thereby improving the monitoring effect. Second, the first camera module 23 and the second camera module 33 can move towards or away from the display module 10, allowing adjustment of the distance between the first camera module 23 and the second camera module 33 and the display module 10 according to the actual situation, thereby controlling the monitoring field of view and further improving the monitoring effect. In addition, it can also adjust the position of the first camera module 23 and the second camera module 33 relative to the examinee according to the actual situation, reducing the risk of the examinee's field of view being obstructed and improving the examinee's examination experience.

[0028] In one embodiment of this implementation, please refer to Figures 1 to 4 , Figure 3 yes Figure 2 A schematic diagram of the structure of the first swing arm 21; Figure 4 yes Figure 2 A schematic diagram of the structure of the second swing arm 31 is provided. The first swing arm 21 has a first sliding groove 211. The first telescopic swing arm 22 extends into the first sliding groove 211 and slides in cooperation with the groove wall of the first sliding groove 211. When the first telescopic swing arm 22 slides, the first swing arm 21 extends out or retracts into the first sliding groove 211. And / or, the second swing arm 31 has a second sliding groove 311. The second telescopic swing arm 32 extends into the second sliding groove 311 and slides in cooperation with the groove wall of the second sliding groove 311. When the second telescopic swing arm 32 slides, the second swing arm 31 extends out or retracts into the second sliding groove 311.

[0029] Specifically, in this embodiment, both the first swing arm 21 and the first telescopic swing arm 22 are square tubes. The hollow portion formed by the tube wall of the square tube-shaped first swing arm 21 is the first sliding groove 211. When the first telescopic swing arm 22 extends into the first sliding groove 211, the tube wall of the first swing arm 21 partially surrounds the first telescopic swing arm 22. Both the second swing arm 31 and the second telescopic swing arm 32 are square tubes. The hollow portion formed by the tube wall of the square tube-shaped second swing arm 31 is the second sliding groove 311. When the second telescopic swing arm 32 extends into the second sliding groove 311, the tube wall of the second swing arm 31 partially surrounds the second telescopic swing arm 32.

[0030] It is understandable that the first sliding groove 211 and the second sliding groove 311 are respectively opened on the first swing arm 21 and the second swing arm 31, and the first telescopic swing arm 22 and the second telescopic swing arm 32 slide in cooperation with the first sliding groove 211 and the second sliding groove 311 respectively. This is beneficial to improving the stability of the first camera module 23 and the second camera module 33 during the movement process, and also to simplifying the structure.

[0031] It should be understood that in some other embodiments, a first groove 211 is formed on the first swing arm 21, and a portion of the first telescopic swing arm 22 extends into the first groove 211 and slides in cooperation with the groove wall of the first groove 211. The second telescopic swing arm 32 and the second swing arm 31 are slidably connected by a sliding guide rail. Alternatively, a second groove 311 is formed on the second swing arm 31, and a portion of the second telescopic swing arm 32 extends into the second groove 311 and slides in cooperation with the groove wall of the second groove 311. The first swing arm 21 and the first telescopic swing arm 22 are slidably connected by a sliding guide rail.

[0032] In some of these embodiments, please refer to Figure 1 and Figure 2The first camera module 20 also includes a third swing arm 25, which is rotatably connected to the display module 10 about an axis parallel to the Y direction. The first swing arm 21 and the third swing arm 25 are rotatably connected about an axis perpendicular to the Y direction. The second swing arm 31 is rotatably connected to the display module 10 about an axis parallel to the X direction. This arrangement makes it easier to adjust the monitoring field of view of the first camera module 23 and the second camera module 33.

[0033] In one embodiment of this implementation, please refer to Figure 1 and Figure 2 The first camera module 23 also includes a first rotating arm 24, which is rotatably connected to the first telescopic arm 22 about a first axis. The first camera module 23 is mounted on the first rotating arm 24, and the first axis is perpendicular to the sliding direction of the first telescopic arm 22 and the first arm 21.

[0034] Specifically, the first axis is perpendicular to the X direction. It can be understood that the first rotating arm 24 can drive the first camera module 23 to rotate around the first axis, thereby adjusting the relative angle between the first camera module 23 and the display module 10, which is beneficial for adjusting the direction of the monitoring field of view.

[0035] In one embodiment of this implementation, please refer to Figure 1 and Figure 2 The first camera module 23 and the first rotating arm 24 are rotatably connected around the second axis, the direction of the second axis intersecting the direction of the first axis.

[0036] Specifically, the direction of the second axis intersects the direction of the first axis and is perpendicular to the sliding direction of the first telescopic arm 22 and the first arm 21. It can be understood that since the direction of the second axis intersects the direction of the first axis, the first camera module 23 can rotate around the first axis and also around the second axis, thereby enabling adjustment of the relative angles between the first camera module 23 and the display module 10 in multiple directions.

[0037] In one embodiment of this implementation, please refer to Figure 1 and Figure 2 The first axis is perpendicular to the second axis.

[0038] Specifically, the direction of the second axis is perpendicular to the Y-direction. This can be understood as follows: the XZ plane is defined as a plane perpendicular to the Y-direction, and the YZ plane is defined as a plane perpendicular to the X-direction. The direction of the second axis is perpendicular to the Y-direction, while the first axis is perpendicular to the X-direction. When the first camera module 23 rotates around the first axis, the angle between the monitoring direction of the first camera module 23 and the YZ plane changes, while the angle between the monitoring direction of the first camera module 23 and the XZ plane remains unchanged. When the first camera module 23 rotates around the second axis, the angle between the monitoring direction of the first camera module 23 and the YZ plane remains unchanged, while the angle between the monitoring direction of the first camera module 23 and the XZ plane changes. This configuration allows the angle between the monitoring direction of the first camera module 23 and the two planes to be adjusted independently, which is beneficial for improving the examinee's testing experience.

[0039] In one embodiment of this implementation, please refer to Figure 1 and Figure 2 The first rotating arm 24 extends in a direction perpendicular to the first axis. One end of the first rotating arm 24 is connected to the first arm 21, which can rotate around the first axis, and the other end is connected to the first camera module 23.

[0040] Specifically, the extension direction of the first rotating arm 24 is perpendicular to the Y direction. This configuration increases the distance between the first camera module 23 and the first axis, so that when the first rotating arm 24 rotates around the first axis, the circumferential radius of the first camera module 23 increases. This allows the examinee to adjust the monitoring direction of the first camera module 23 while also adjusting the distance between the first camera module 23 and the display module 10, thereby improving the examinee's adjustment efficiency of the first camera module 23.

[0041] In one embodiment of this implementation, please refer to Figure 1 and Figure 2 The second camera module 33 also includes a second rotating arm 34, which is rotatably connected to the second telescopic arm 32 about a third axis. The second camera module 33 is mounted on the second rotating arm 34, and the third axis is perpendicular to the sliding direction of the second telescopic arm 32 and the second arm 31.

[0042] Specifically, the third axis is perpendicular to the X-direction. It can be understood that the second rotating arm 34 can drive the second camera module 33 to rotate around the third axis, thereby adjusting the relative angle between the second camera module 33 and the display module 10, which is beneficial for adjusting the direction of the monitoring field of view.

[0043] In one embodiment of this implementation, please refer to Figures 1 to 2 The second rotating arm 34 extends in a direction perpendicular to the third axis. One end of the second rotating arm 34 is rotatably connected to the second arm 31 around the third axis, and the other end is connected to the second camera module 33.

[0044] Specifically, the extension direction of the second rotating arm 34 is perpendicular to the Y-direction. This configuration increases the distance between the second camera module 33 and the third axis, thereby increasing the radius of the circular motion of the second camera module 33 when the second rotating arm 34 rotates around the third axis. This allows the examinee to adjust the monitoring direction of the second camera module 33 while simultaneously adjusting the distance between the second camera module 33 and the display module 10, thus improving the examinee's adjustment efficiency of the second camera module 33.

[0045] In one embodiment of this implementation, please refer to Figures 1 to 4 The first telescopic arm 22 can slide relative to the first slide groove 211 along the length direction of the first telescopic arm 22, and the second telescopic arm 32 can slide relative to the second slide groove 311 along the length direction of the second telescopic arm 32. The length of the second telescopic arm 32 is greater than the length of the first telescopic arm 22.

[0046] Specifically, the length of the second slide rail 311 is greater than the length of the first slide rail 211. It can be understood that the distance the first telescopic arm 22 can slide relative to the first slide rail 211 is determined by the length of the first telescopic arm 22, and the distance the second telescopic arm 32 can slide relative to the second slide rail 311 is determined by the length of the second telescopic arm 32. Setting the length of the second telescopic arm 32 to be greater than the length of the first telescopic arm 22 allows the distance between the second camera module 33 and the display module 10 to be greater than the distance between the first camera module 23 and the display module 10. Setting the first camera module 23 and the second camera module 33 at different distances from the display module 10 is beneficial for improving the monitoring effect.

[0047] In one embodiment of this implementation, please refer to Figure 1 and Figure 2 The display module 10 includes a display module 11 and a base 12. The display module 11 is rotatably connected to the base 12. The first swing arm 21 is connected to the base 12, and the second swing arm 31 is connected to the base 12.

[0048] Specifically, the display module 11 can rotate around a rotation axis parallel to the Y direction. It can be understood that when the display module 11 rotates, the angle between the display module 11 and the candidate's line of sight changes, allowing the candidate to adjust the rotation angle of the display module 11 according to the actual situation, which helps improve the candidate's examination experience.

[0049] It should be understood that, in some embodiments, please refer to Figures 1 to 2 The display module 11 is equipped with a third camera module 13, which is used to identify the examinee. When the display module 11 rotates relative to the base 12, it drives the third camera module 13 to rotate as well. This configuration can improve the monitoring effect of the student experimental examination terminal 100.

[0050] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
