[0028] 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.
[0029] This utility model provides a student experimental examination terminal 100. Please refer to [link / reference]. Figures 1 to 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 1 A 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 and a first camera module 23. The first camera module 23 is connected to the first swing arm 21, and the first swing arm 21 is rotatably connected to the display module 10 around a first axis. The second camera module 30 includes a second swing arm 31 and a second camera module 33. The second camera module 33 is mounted on the second swing arm 31, and the second swing arm 31 is rotatably connected to the display module 10 around a second axis, which is perpendicular to the first axis. When the first swing arm 21 and the second swing arm 31 rotate, they can move the first camera module 23 and the second camera module 33 to adjacent sides of the display module 10, so that the first camera module 20 and the second camera module 30 are in a retracted state.
[0030] Specifically, the first swing arm 21 is rotatably connected to the display module 10 by a torque hinge, with the first axis parallel to the Y direction; the second swing arm 31 is rotatably connected to the display module 10 by a torque hinge, with the second axis parallel to the X direction.
[0031] Understandably, please refer to Figure 3 , Figure 3 yes Figure 1A schematic diagram of the student experimental examination terminal 100 in its stowed state. When the first camera module 20 and the second camera module 30 are in the stowed state, the first camera module 23 is located on one side of the display module 10 along the Y direction, and the second camera module 33 is located on one side of the display module 10 along the X direction. This arrangement helps to reduce the size of the student experimental examination terminal 100 in the Z direction.
[0032] The student experimental examination terminal 100 of this utility model has a first camera module 23 and a second camera module 33 connected to a first swing arm 21 and a second swing arm 31, respectively. Both the first swing arm 21 and the second swing arm 31 are rotatably connected to the display module 10. When the first swing arm 21 and the second swing arm 31 rotate, they can drive the first camera module 23 and the second camera module 33 to move to the adjacent sides of the display module 10, so that the first camera module 20 and the second camera module 30 are in a stored state, thereby making the student experimental examination terminal 100 easy to store.
[0033] In one embodiment of this implementation, please refer to Figures 1 to 2 The first camera module 20 also includes a third swing arm 24, which is rotatably connected to the first swing arm 21. The rotation axis of the third swing arm 24 is perpendicular to the first axis, and the first camera module 23 is mounted on the third swing arm 24.
[0034] Specifically, the axis of rotation of the third swing arm 24 relative to the first swing arm 21 is perpendicular to the Y-direction. It can be understood that the first swing arm 21 can drive the third swing arm 24 to rotate, with the axis of rotation of the third swing arm 24 perpendicular to the Y-direction and the axis of rotation of the first swing arm 21 perpendicular to the X-direction. Defining the XZ plane as a plane perpendicular to the Y-direction and the YZ plane as a plane perpendicular to the X-direction, this configuration allows the angle between the monitoring field of view of the first camera module 23 and the XZ plane to change when the third swing arm 24 drives the first camera module 23 to rotate. It also allows the angle between the monitoring field of view of the first camera module 23 and the YZ plane to change when the first swing arm 21 rotates. This configuration allows the angle between the monitoring field of view of the first camera module 23 and both planes to be adjusted, thereby enabling adjustment of the relative angles between the first camera module 23 and the display module 10 in multiple directions. This improves the applicability of the student experimental examination terminal 100.
[0035] In some of these embodiments, please refer to Figures 1 to 2The first camera module 20 also includes a first telescopic arm 25 that slides with the third arm 24. The first camera module 23 is connected to the first telescopic arm 25. When the first telescopic arm 25 slides relative to the third arm 24, it can drive the first camera module 23 to move in a direction closer to or further away from the display module 10. Both the third arm 24 and the first telescopic arm 25 are square tubes. The hollow portion formed by the tube wall of the square arm 24 is partially surrounded by the tube wall of the third arm 24 when the first telescopic arm 25 extends into the hollow portion. The tube wall of the third arm 24 slides with the first telescopic arm 25. It can be understood that the first telescopic arm 25 can drive the first camera module 23 to move in a direction closer to or further away from the display module 10, which can adjust the distance between the first camera module 23 and the display module 10 according to the actual situation, thereby controlling the monitoring field of view and improving the monitoring effect.
[0036] In some of these embodiments, please refer to Figures 1 to 2 The second camera module 30 also includes a second telescopic swing arm 34 that slides with the second swing arm 31. The second camera module 33 is connected to the second telescopic swing arm 34. When the second telescopic swing arm 34 slides relative to the second swing arm 31, it can drive the second camera module 33 to move in a direction closer to or further away from the display module 10. Both the second swing arm 31 and the second telescopic swing arm 34 are square tubes. The hollow portion formed by the tube wall of the square-tube second swing arm 31 is partially surrounded by the tube wall of the second telescopic swing arm 31 when the second telescopic swing arm 34 extends into the hollow portion. The tube wall of the second swing arm 31 slides with the second telescopic swing arm 34. It can be understood that the second telescopic swing arm 34 can drive the second camera module 33 to move in a direction closer to or further away from the display module 10, which can adjust the distance between the second camera module 33 and the display module 10 according to the actual situation, thereby controlling the monitoring field of view and improving the monitoring effect.
[0037] In some of these embodiments, please refer to Figures 1 to 2 The first camera module 20 also includes a first rotating arm 26, which is rotatably connected to a first telescopic arm 25 about an axis perpendicular to the X-direction. The first camera module 23 is mounted on the first rotating arm 26. The second camera module 33 also includes a second rotating arm 35, which is rotatably connected to a second telescopic arm 34 about an axis perpendicular to the X-direction. The second camera module 33 is mounted on the second rotating arm 35. This arrangement makes it easier to adjust the monitoring field of view of the first camera module 23 and the second camera module 33.
[0038] In one embodiment of this implementation, please refer to Figures 1 to 3The display module 10 has an adjacent first side 11 and a second side 12. The first swing arm 21 is located on the side of the first side 11 along the direction parallel to the first axis, and the first side 11 is perpendicular to the first axis. The second swing arm 31 is located on the side of the second side 12 along the direction parallel to the second axis, and the second side 12 is perpendicular to the second axis.
[0039] Specifically, the first side 11 is perpendicular to the Y-direction, and the second side 12 is perpendicular to the X-direction. The first swing arm 21 can drive the first camera module 23 to move along the Y-direction side of the first side 11, and the second swing arm 31 can drive the second camera module 33 to move along the X-direction side of the second side 12. It can be understood that the first swing arm 21 can drive the first camera module 23 to move to the Y-direction side of the display module 10, and the second swing arm 31 can drive the second camera module 33 to move to the X-direction side of the display module 10. This arrangement ensures that when the student experimental examination terminal 100 is in the retracted state, the first camera module 20 is entirely located on the Y-direction side of the display module 10, and the second camera module 30 is entirely located on the X-direction side of the display module 10, which helps reduce the size of the student experimental examination terminal 100 in the Z-direction when it is in the retracted state.
[0040] In one embodiment of this implementation, please refer to Figures 1 to 3 The display module 10 also has a bottom surface 13, which is perpendicular to the first side surface 11. The first swing arm 21 has a first support surface 211, which is parallel to the first axis. The first swing arm 21 can drive the first camera module 23 to rotate so that the first camera module 20 is in use. When the first camera module 20 is in use, the first support surface 211 is flush with the bottom surface 13.
[0041] Specifically, the first support surface 211 is parallel to the Y direction, and the bottom surface 13 is perpendicular to the Z direction. It can be understood that during the use of the student experimental examination terminal 100, the terminal is placed on the support surface, with the bottom surface 13 abutting against it. When the first camera module 20 is in use, the first support surface 211 is flush with the bottom surface 13, allowing it to also abut against the support surface. This arrangement increases the contact area between the student experimental examination terminal 100 and the support surface, thereby improving the stability of the terminal.
[0042] In one embodiment of this implementation, please refer to Figures 1 to 3 When the first camera module 20 is in the retracted state, the first support surface 211 is flush with the second side surface 12.
[0043] Specifically, the angle between the bottom surface 13 and the second side surface 12 is 90 degrees. Both the bottom surface 13 and the second side surface 12 are parallel to the Y direction. The first swing arm 21 can rotate 90 degrees around an axis parallel to the Y direction, so that the first camera module 20 can be switched from the use state to the storage state, and the first support surface 211 can be switched from being flush with the bottom surface 13 to being flush with the second side surface 12. It can be understood that the second swing arm 31 can drive the second camera module 33 to move along one side of the second side surface 12 in the X direction. The first support surface 211 being flush with the second side surface 12 helps to reduce the risk of interference between the first camera module 20 and the second camera module 30.
[0044] In one embodiment of this implementation, please refer to Figure 2 A first abutting member 22 is provided on the first supporting surface 211, and the first abutting member 22 is used to abut against the bearing surface.
[0045] Specifically, the first abutment 22 can be magnetically, adhesively, or snap-fitted onto the first support surface 211. It is understood that the first abutment 22 can cover part of the first support surface 211, which helps reduce the risk of wear on the first support surface 211.
[0046] In one embodiment of this implementation, please refer to Figures 1 to 3 The first swing arm 21 is provided with a transition surface 212, which is parallel to the first axis. The transition surface 212 is connected to the first support surface 211. The distance from each point on the transition surface 212 to the first axis is less than the distance from the first axis to the bottom surface 13.
[0047] Specifically, the transition surface 212 is parallel to the Y direction and smoothly connected to the first support surface 211. It is understood that when the student experimental examination terminal 100 is placed on the support surface and the first swing arm 21 rotates, the transition surface 212 moves relative to the support surface. The distance from each point on the transition surface 212 to the first axis is less than the distance from the first axis to the bottom surface 13, which reduces the risk of the transition surface 212 contacting the support surface and facilitates smooth rotation of the first swing arm 21.
[0048] In one embodiment of this implementation, please refer to Figures 1 to 3 The bottom surface 13 is perpendicular to the second side surface 12. The second swing arm 31 is provided with a second support surface 311, which is parallel to the second axis. The second swing arm 31 can drive the second camera module 33 to rotate so that the second camera module 30 is in use. When the second camera module 30 is in use, the second support surface 311 is flush with the bottom surface 13.
[0049] Specifically, the second support surface 311 is parallel to the X direction. It can be understood that when the second camera module 30 is in use, the second support surface 311 is flush with the bottom surface 13, so that the second support surface 311 can also abut against the bearing surface. This setting helps to increase the contact area between the student experimental examination terminal 100 and the bearing surface, thereby improving the stability of the student experimental examination terminal 100.
[0050] In one embodiment of this implementation, please refer to Figure 2 A second abutment 32 is provided on the second support surface 311, and the second abutment 32 is used to abut against the bearing surface.
[0051] Specifically, the second abutment 32 can be magnetically, adhesively, or snap-fitted onto the second support surface 311. It is understood that the second abutment 32 can cover part of the second support surface 311, which helps reduce the risk of wear on the second support surface 311.
[0052] In one embodiment of this implementation, please refer to Figures 1 to 2 The distance from the second camera module 33 to the second axis is greater than the distance from the first camera module 23 to the first axis.
[0053] Specifically, one end of the first swing arm 21 is connected to the display module 10 and the other end is connected to the first camera module 23. One end of the second swing arm 31 is connected to the display module 10 and the other end is connected to the second camera module 33. The length of the second swing arm 31 is greater than the length of the first swing arm 21.
[0054] It is understandable that the distance from the second camera module 33 to the second axis is greater than the distance from the first camera module 23 to the first axis, which makes the distance between the second camera module 33 and the display module 10 greater than the distance between the first camera module 23 and the display module 10, thus improving the monitoring effect.
[0055] In some of these embodiments, please refer to Figures 1 to 2 The display module 10 includes a display module 14 and a base 15. The display module 14 and the base 15 are rotatably connected about an axis parallel to the Y direction. A first swing arm 21 and a second swing arm 31 are connected to the base 15. It is understood that the display module 14 is used for display. When the display module 14 rotates, the angle between the display module 14 and the candidate's line of sight changes, allowing the candidate to adjust the rotation angle of the display module 14 according to the actual situation, which helps improve the candidate's examination experience.
[0056] It should be understood that, in some embodiments, please refer to Figures 1 to 2A third camera module 16 is installed on the display module 14. The third camera module 16 is used to identify the examinee. When the display module 14 rotates relative to the base 15, it drives the third camera module 16 to rotate as well. This configuration can improve the monitoring effect of the student experimental examination terminal 100.
[0057] 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.
