Specific implementation mode

[0022] The present utility model will be further described below with reference to the accompanying drawings.

[0023] As Figure 1 shown, a mobile recording and broadcasting terminal including a multi - angle wireless video booth includes a base 1, a column 2, a wireless video booth 3, a universal arm 4 and a surgical field camera 5. A plurality of universal wheels 8 are provided at the bottom of the base 1. The mobile recording and broadcasting terminal takes the base as the main body and can achieve omnidirectional movement and fixation based on the universal wheels. A plurality of functional modules including a power module, a counterweight block, and a local sound reinforcement module are provided inside the base 1, which is the basic part of the entire mobile recording and broadcasting terminal. The column 2 is vertically fixed on the upper part of the base and is used to carry a plurality of audio - video acquisition modules. An opening groove is provided on the side of the column 2 close to the user, and this opening groove cooperates with the base slide rails of each audio - video acquisition module to achieve the up - and - down movement of the audio - video acquisition module. In response to the problem that the existing mobile recording and broadcasting terminal cannot simultaneously achieve multi - angle audio - video acquisition, the present application designs a rotatable multi - angle wireless video booth. The specific structure of the wireless video booth is as Figures 2 - 4 shown.

[0024] The wireless video booth 3 includes a slide rail part 31, an extension part 32 and a rotating arm 33. The slide rail part 31 is hinged to the extension part 32, and its cross - section is I - shaped, which cooperates with the opening groove of the column 2 to achieve axial position adjustment. The extension part 32 can be rotated to any position within the range from 0 degrees to the maximum extension angle according to requirements. In this embodiment, the extension part 32 can be fixed at any position from the 0 - degree position (parallel and attached to the slide rail part 31) to the position perpendicular to the slide rail part 31 (i.e., 90 degrees). A rotating arm 32 is provided at the other end of the extension part 32, and the rotating arm 32 can rotate to any angle along the axis of the extension part 32. As Figures 2 - 3As shown, a first camera 35 and a second camera 36 are respectively arranged on the upper and lower end faces of the rotating arm 32. An array microphone is also arranged outside the second camera 36 on the lower end face. Through the structural design of the dual cameras in this application, the effect of simultaneous multi-angle shooting during rotation is achieved, and the array microphone can effectively collect audio data in the current environment.

[0025] A number of auxiliary modules are arranged on the lower side surface of the extending part 32. A first buffer pad 37 and a second buffer pad 38 are respectively arranged at both ends of the extending part 32. The buffer pads are provided with protruding parts, which are used to protect the other auxiliary modules when the extending part 32 is stored parallel to the slide rail part 31. A heat dissipation hole 39 and an illumination array 210 are sequentially arranged between the first buffer pad 37 and the second buffer pad 38. A number of function buttons are respectively arranged on the upper side surface of the extending part 32, including an illumination array switch, a wireless video booth power switch, etc.

[0026] In addition to the wireless video booth, a training host 6, a panoramic camera 9 and a display base 7 are also arranged on the upper part of the column. The training host 6 and the display base 7 are respectively fixed at the upper and lower ends of the wireless video booth 3, and the wireless video booth 3 slides between the training host 6 and the display base 7. The panoramic camera 9 is installed on the upper part of the training host 6, and its base adopts the same structure as the slide rail part 31 and cooperates with the column 2 to slide and be fixed at any position between the top of the column 2 and the training host 6. The universal arm 4 includes a first arm 41, a second arm 42 and a third arm 43 which are sequentially hinged. One end of the first arm 41 is fixed to the top of the column 2, and the third arm 43 is connected to the operative field camera 5. A fixing plate is arranged on the top of the operative field camera 5 and is rotatably fixed to the end of the third arm 43 through the fixing plate. Through the flexible position adjustment of the universal arm 4, the operative field camera can adjust the optimal recording and broadcasting posture and complete the audio and video acquisition work.

[0027] The above are only the preferred embodiments of the present utility model. It should be pointed out that for those of ordinary skill in the art of this technology, without departing from the principle of the present utility model, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
