DETAILED DESCRIPTION

[0031] In order for those skilled in the art to better understand the utility model, the utility model technical scheme is further explained below in combination with the drawings and examples.

[0032] As Figures 1-5 Indicated, a direct recording and broadcasting equipment based on multi-scene teaching includes the desk 1, the computer equipment 2 and the camera 3, the camera 3 is arranged on the desk 1, and the mobile assembly is arranged between the camera 3 and the desk 1.

[0033] The desk 1 is the basic support platform of the whole teaching direct recording and broadcasting equipment, provides the placement space for the computer equipment 2 and the camera 3 and other components, is the platform of the teacher's teaching, and is the main area of the teacher's operation such as small experiment in class, display props, etc. The computer equipment 2 can specifically include display screen, computer host, microphone and keyboard mouse and other equipment, which are all common live broadcast equipment, so detailed description and display are not made. The camera 3 is electrically connected with the computer equipment 2, is responsible for shooting the picture in the teaching process, including the figure picture of the teacher, the experiment and prop display on the desk and other contents, and converts the image shot into electric signal and transmits to the computer equipment 2.

[0034] The mobile assembly includes:

[0035] The track 31 is fixedly arranged on the upper edge of the desk 1 along the length direction of the desk 1. The track 31 provides a path and a guide for the movement of the camera 3, ensuring that the camera 3 can move stably along the length direction of the desk 1, thereby achieving shooting at different positions on the desk.

[0036] The slider 32 is sleeved on the track 31. By being sleeved on the track 31, the slider 32 can make linear sliding motion on the track 31 under the guidance of the track 31 when subjected to external force (such as manual pushing or motor driving). The slider 32 serves as an intermediate component connecting the track 31 and the base plate 33, and moves on the track 31 to drive the base plate 33 and the camera 3 connected thereto to move.

[0037] The base plate 33 is fixedly arranged on the slider 32. The base plate 33 provides a mounting basis for the connecting plate 34 and the bracket 35, and transmits the motion of the slider 32 to the connecting plate 34 and the bracket 35, thereby driving the camera 3 to move.

[0038] The connecting plate 34 is arranged on the base plate 33. It serves to connect the base plate 33 and the bracket 35, and can adjust the mounting angle and position of the bracket 35 as needed to meet different shooting requirements. The connecting plate 34 is connected to the base plate 33 and the bracket 35 by bolts, nuts and other connecting components. Users can adjust the angle and position between the connecting plate 34 and the base plate 33 or the bracket 35 by loosening the connecting components, and then tighten the connecting components for fixation.

[0039] The bracket 35 is arranged on the connecting plate 34, and the camera 3 is arranged at the end of the bracket 35 away from the connecting plate 34. The bracket 35 supports the camera 3 and installs the camera 3 at a suitable height and position, facilitating shooting of the content on the desk.

[0040] Through the cooperative work of the above components, the entire multi-scene teaching direct recording and broadcasting device can realize flexible shooting function. When the teacher needs to shoot experiments or prop displays at different positions on the desk, the user only needs to push the slider 32 to make it slide on the track 31, which can quickly and stably drive the camera 3 to the desired position, thereby capturing key pictures in the teaching process in time. At the same time, the computer device 2 can process and live stream the pictures shot by the camera 3, providing students with clear and smooth teaching videos. This design effectively solves the problem of inconvenient camera position switching in the existing teaching direct recording and broadcasting process, and improves the teaching efficiency and quality.

[0041] Further, the track 31 is T-shaped, the slider 32 is matched with the track 31, and a plurality of balls 321 are arranged on the side of the slider 32 close to the upper end of the track 31 and are embedded in the track 31 by rolling. The balls 321 abut against the track 31.

[0042] The T-shaped track has a unique shape advantage, which can provide reliable guidance and limiting function for the slider 32. It can effectively prevent the slider 32 from shaking left and right or leaving the track during sliding, ensuring the stable movement of the slider 32 and the camera 3 installed thereon along the predetermined path.

[0043] The matching design of the slider 32 enables the slider 32 to closely fit on the track 31, and the slider 32 also fits on the track 31 in the same shape as the track 31, ensuring good cooperation between the two.

[0044] The plurality of rolling balls 321 are embedded on one side of the slider 32 close to the upper end of the track 31. The rolling balls 321 are mainly used to reduce the friction between the slider 32 and the track 31. When the slider 32 slides on the track 31, the rolling balls 321 roll between the slider 32 and the track 31. Compared with the direct sliding friction between the slider 32 and the track 31, the rolling friction has much smaller friction. The reduction of friction makes it easier to push the slider 32 and more convenient to operate, while also reducing the wear between the track 31 and the slider 32.

[0045] Further, the track 31 is provided with a limiting block 311 at both ends, and the limiting block 311 and the track 31 are respectively provided with a matching connecting hole inside which a screw rod 312 is screwed.

[0046] The limiting block 311 is installed at both ends of the track 31, and its main function is to prevent the slider 32 from sliding off the track 31. During teaching, when the camera 3 needs to be moved, the slider 32 will slide on the track 31. If there is no limiting block 311, the slider 32 may be separated from the track 31 due to excessive sliding, which may cause damage to the camera 3 or affect the continuity of shooting. The limiting block 311 provides a boundary limit for the sliding of the slider 32, ensuring the safety and stability of the equipment.

[0047] The matching connecting holes on the track 31 and the limiting block 311 and the screw rod 312 screwed inside are used to fix the limiting block 311 at both ends of the track 31. This detachable connection makes it very convenient to install and disassemble the limiting block 311. During the installation, debugging or maintenance of the equipment, if it is necessary to replace or adjust the position of the limiting block 311, only the screw rod 312 needs to be unscrewed, without complicated operation.

[0048] Further, the slider 32 is provided with a wiring ring 322 on one side close to the edge of the desk 1.

[0049] When the teaching live broadcast equipment is running, the camera 3 needs to be connected to power lines, data lines and other cables. If these cables are placed randomly, they are easy to entangle and knot, which not only affects the appearance, but also may be damaged by being pulled when the equipment is moved. The wiring ring 322 provides an orderly storage position for the cables, which can concentrate and fold the cables and arrange them along the wiring ring, making the layout of the entire desktop area neat and orderly. Just like multimedia equipment in a classroom, if various cables are not arranged, they will appear messy, and the wiring ring 322 can effectively avoid such situations.

[0050] Further, the sliding block 32 is provided with a threaded hole, and a fixed screw 323 is screwed into the threaded hole.

[0051] During the teaching live broadcast or recording process, the teacher may need to fix the camera 3 at a certain position on the desk to clearly show the experiment or props. By means of the fixed screw 323, the sliding block 32 can be stably fixed at the corresponding position of the track 31, so as to ensure that the camera 3 can accurately aim at the target to be shot, and avoid the influence of accidental touch or vibration on the sliding block 32 and the shooting effect. Specifically, when the position of the camera 3 needs to be changed, the fixed screw 323 is loosened, and the sliding block 32 can freely slide on the track 31, so as to conveniently and quickly adjust to a new position, and then the fixed screw 323 is tightened for fixation. This design makes the position adjustment of the camera 3 more flexible, which can adapt to different teaching scenes and shooting requirements.

[0052] Further, a rotating handle 324 is arranged at the upper end of the fixed screw 323.

[0053] In the teaching live broadcast or recording scene, the teacher needs to frequently adjust the position of the camera 3 and fix the sliding block 32. If there is no rotating handle 324, it is more laborious to directly twist the fixed screw 323, and the hand is easy to slip. The rotating handle 324 increases the contact area with the hand, so that the teacher can hold and exert force more easily, and only needs to rotate the handle to quickly tighten or loosen the fixed screw 323, which is more comfortable and convenient to operate.

[0054] Further, a plurality of threaded holes 331 and a plurality of through grooves 332 are arranged on the base plate 33, and the connecting plate 34 is screwed at the threaded holes 331 and / or the through grooves 332 of the base plate 33.

[0055] The plurality of threaded holes 331 and through-slots 332 provided on the base plate 33 provide a plurality of mounting positions for the connecting plate 34. The teacher can flexibly adjust the mounting position of the connecting plate 34 on the base plate 33 according to the actual teaching needs, such as the position of the experimental demonstration, the requirement of the shooting angle, etc., so as to change the position and angle of the camera 3 to obtain the best shooting effect. At the same time, in the teaching direct recording and broadcasting scene, the sound collection quality is crucial. The plurality of threaded holes 331 and through-slots 332 on the base plate 33 provide additional mounting positions, so that a microphone or the like can be mounted on the base plate 33. In this way, the microphone can move together with the slider 32 on the track 31 along with the camera 3, ensuring that good sound collection effect can be achieved when teaching content in different positions is shot. For example, when an experiment on a desk is demonstrated, the microphone can clearly record the sound in the experimental process at close range, such as the operation sound of the instrument, the explanation sound, etc., to provide students with a better audio-visual experience. Specifically, similar to the mounting method of the connecting plate 34, the microphone or the like can be threadedly connected to the threaded holes 331 on the base plate 33 through screws to achieve stable installation. If the position of the device mounting hole does not completely match the threaded hole 331, the through-slot 332 can also be used to adjust the position of the screw to flexibly fix the device on the base plate 33.

[0056] The design of the threaded holes 331 and through-slots 332 on the base plate 33 greatly enhances the functionality and compatibility of the teaching direct recording and broadcasting device. It can not only conveniently install auxiliary devices such as microphones to improve the collection quality of teaching content, but also adapt to different models of connecting plates 34 to provide the possibility for flexible configuration and upgrading of the device, meeting the diversified teaching needs.

[0057] Further, the support 35 includes a first rod body 351 and a second rod body 352, the first rod body 351 is connected with the connecting plate 34, the first rod body 351 and the second rod body 352 are hingedly connected with each other, and the second rod body 352 is hingedly connected with the camera 3.

[0058] Hinge connection is a connection method that allows two components to rotate relative to each other around an axis. In the support 35, the hinge point between the first rod body 351 and the second rod body 352 forms a rotation axis. When an external force is applied to make one of the rod bodies rotate around the hinge point, the relative position of the other rod body will also change, thereby achieving angle adjustment. Similarly, the hinge connection between the second rod body 352 and the camera 3 also enables the camera 3 to rotate around the hinge point, further increasing the adjustment range of the shooting angle.

[0059] The first rod body 351 and the second rod body 352 are hinged to each other, and the second rod body 352 is hinged to the camera 3, so that the camera 3 can be adjusted in multiple dimensions. In the teaching process, the teacher can easily change the shooting angle of the camera 3 according to different teaching content and display requirements. For example, when a small experiment on the desk is performed, the camera 3 can be adjusted to a downward shooting angle to clearly show the operation details of the experiment; if the teacher's explanation action needs to be displayed, the camera 3 can be adjusted to a horizontal viewing angle.

[0060] Since the rod bodies are hinged, the support 35 can be folded when the device is not in use. The first rod body 351 and the second rod body 352 can be relatively folded to reduce the space occupied by the entire support 35. This is very practical for teaching scenarios that require frequent movement or storage of the device, making it easy for teachers to carry and store the device, and improving the portability of the device.

[0061] Further, a rotating disc 353 is arranged between the first rod body 351 and the connecting plate 34, the first rod body 351 is hinged to the rotating disc 353, and the rotating disc 353 is rotationally connected to the connecting plate 34.

[0062] The rotating disc 353 enables the first rod body 351 to rotate in a horizontal direction to a greater extent. In a teaching scenario, the teacher may need to display the experiment, props, etc. on the desk from different horizontal angles. Through the rotating disc 353, the camera 3 can easily adjust the angle in the horizontal direction, such as turning from one end of the desk to the other end, to display the teaching content on the desk in all directions, providing students with a richer perspective and enhancing the intuitiveness and comprehensiveness of teaching.

[0063] When the device is in use, during normal teaching, if the teacher's figure needs to be shot, the slider 32 is pushed to move the camera 3 to the appropriate position, and the fixed screw 323 is tightened to fix it. When the experiment on the desk or the props display needs to be shot, the slider 32 is pushed again to quickly move the camera 3 above the target area. If the display position changes, the fixed screw 323 can be loosened for fine adjustment before being fixed again. In terms of shooting angle, the first rod body 351 and the second rod body 352 of the support 35 are hinged, and the second rod body 352 is hinged to the camera 3, so that the pitch angle of the camera 3 can be adjusted. For example, when shooting the experiment details, the camera 3 is adjusted to a downward shooting angle, and when displaying the teacher's action, the camera 3 is adjusted to a horizontal viewing angle. In addition, the rotating disc 353 can realize the rotation of the first rod body 351 in the horizontal direction, thereby enabling the camera 3 to display the teaching content on the desk in all directions.

[0064] After the teaching is completed, the power of the computer device 2 and the camera 3 is turned off, the fixed screw 323 is loosened, and the slider 32 is moved to one end of the track 31. The support 35 is folded to relatively fold the first rod body 351 and the second rod body 352, thereby reducing the occupied space and facilitating storage and next use of the device.

[0065] The above embodiments only exemplarily illustrate the principles and effects of the present application, and are not intended to limit the present application. Any person skilled in the art can modify or change the above embodiments without departing from the spirit and scope of the present application. Therefore, all equivalent modifications or changes made by those skilled in the art without departing from the spirit and technical concept disclosed by the present application should be covered by the claims of the present application.
