Detailed Description

The invention is described in further detail below with reference to the figures and the specific embodiments.

The micro-classroom recording and broadcasting device of the intelligent blackboard shown in fig. 1 and 2 comprises a screw rod 1, a camera 2, a recorder 3, a host 4, a worm wheel 5, a worm 6 and a rocker 7;

two ends of the screw rod 1 are horizontally arranged on a wall body provided with the intelligent blackboard body 14 through a bearing seat 11, and the screw rod 1 is higher than the upper end of the intelligent blackboard body 14;

a threaded sleeve 8 is matched with the screw rod 1 through threads; the thread sleeve 8 is provided with a camera bracket 12, and the camera 2 and the recorder 3 are respectively arranged on the camera bracket 12 and are electrically connected with the host 4;

one end of the screw rod 1 is connected with a worm wheel 5; the worm 6 is vertical to be set up and cooperates with the

worm wheel

5, and 6 upper ends of the worm and lower extreme are equipped with installing support 13 respectively, and installing support 13 is connected with the wall body that is equipped with

wisdom blackboard body

14, and 6 upper ends of the worm and lower extreme are equipped with respectively with installing support 13 complex bearing.

The lower end of the worm 6 is also connected with a rocker 7. The rocker 7 in this embodiment is an L-shaped rod, the horizontal portion of which is fixed to the worm 6, and the vertical portion of which is eccentrically disposed with respect to the worm 6. In addition, preferably, the vertical part and the horizontal part are matched through a bearing, the vertical part is held by a hand and the vertical part is pushed, so that the horizontal part and the worm 6 fixed with the horizontal part rotate, the worm 6 rotates to drive the worm wheel 5 to rotate, the screw rod 1 is driven to rotate, the threaded sleeve 8 in threaded fit on the screw rod 1 moves along the length direction of the screw rod 1, and the position adjustment of the camera 2 and the position adjustment of the recorder 3 are realized.

In addition, the lamp bracket 9 is also arranged on the camera bracket 12; the light bracket 9 is provided with a light supplement lamp 10 electrically connected with the host 4. The setting height of the light supplement lamp 10 is higher than that of the camera 2. The lamp holder 9 of the present embodiment is rod-shaped or plate-shaped and is arranged parallel to the screw 1. The lamp support 9 is located camera 2 both sides and is equipped with a plurality of light filling lamps 10 respectively the symmetry. The supplementary lighting lamp 10 is preferably disposed in an inclined manner, and the light emitting direction of the supplementary lighting lamp 10 is directed to the intelligent blackboard body 14.

The host 4 is electrically connected to the camera 2, the recorder 3 and the fill-in light 10 through electric wires, and the host 4 can be installed at any position in a classroom, and in this embodiment, the host 4 is preferably installed near the intelligent blackboard body 14. It should be noted that, in this embodiment, the host 4 is mainly used to call and store the video file shot by the camera 2 and the recording file recorded by the recorder 3, and a control button is provided to control the power on and off of the camera 2 and the recorder 3, and a specific implementation method of the host 4 may be implemented by using the prior art, which is not limited in this embodiment.

When the teacher taught, switched on camera 2 and recorder 3 through host computer 4 to rotate rocker 7 regulation and control camera support 12 and remove to suitable position, the teacher normally imparts knowledge to students can, camera 2 will shoot the whole process and the blackboard writing picture that the teacher taught automatically, and the voice of teacher is recorded in the synchronization of recorder 3, and finally forms the video and the audio file of MP4 format in host computer 4. Of course, if the host 4 is provided with a network communication module, the corresponding video and audio files can be synchronously relayed to the network platform, so as to realize live broadcast teaching.

The advantages of this embodiment are: because wisdom blackboard body 14 length is longer, and the required shooting face of camera equipment is wider, if adopt traditional fixed camera equipment, then camera equipment need place and shoot at the position far away from wisdom blackboard body 14, shoots the picture unclear, and easily has other contents irrelevant with wisdom blackboard body 14 show picture and teacher's writing on blackboard content in the picture. If the movable camera equipment provided with the holder and the slide rail is adopted, the shooting personnel need to be additionally arranged to track and shoot, and the movable camera equipment is not suitable for long-term teaching recording and broadcasting. In the present embodiment, the camera holder 12 is provided to enlarge the distance between the camera 2 and the intelligent blackboard body 14, so that the camera 2 has a wider shooting area. Because the intelligent blackboard is arranged at a position higher than the intelligent blackboard body 14, people except teachers are not easy to appear in the shot picture. The position of the camera 2 can be adjusted by rotating the rocker 7, additional shooting personnel do not need to be equipped, and a teacher can finish recording and broadcasting in the whole classroom by one person.

It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that a person skilled in the art should also recognize that several modifications and decorations can be made without departing from the principle of the present invention, and the protection scope of the present invention is also covered.
