[0027] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0028] See Figures 1 to 7As shown in the figure, this application discloses a foldable portable smart podium, including a cabinet 1 and upright panels 2 on both sides of it. The rear ends of the two upright panels 2 are respectively connected to the two sides of the rear end of the cabinet 1. The front ends of the two upright panels 2 are flared out, and the lower end surfaces of the two upright panels 2 are flush with the lower end surface of the cabinet 1. The upper end surfaces of the two upright panels 2 are higher than the upper end surface of the cabinet 1 to form an upper panel. A platform is provided on the top of the cabinet 1 and between the two upright panels 2. A speaker is embedded in the rear end of the cabinet 1, and a microphone 3 that is electrically connected to the speaker is detachably inserted into the platform. In addition, a control panel is provided on the upper surface of the rear end of the platform. The device 4 and controller 4 are electrically connected to the speaker. In this structure, the speaker function can be adjusted by operating the controller 4, which is very convenient. Moreover, the size of this podium structure is greatly reduced compared to the traditional podium. It only includes a vertical square column-shaped cabinet 1 and two uprights 2. The two uprights 2 surround and cover most of the cabinet 1. From the front of the podium, only the rear upright of the cabinet 1 can be seen. Furthermore, a channel for the sound of the speaker to pass through is opened on the rear upright 2. The entire podium structure is simple, compact, and easy to move. In addition, it comes with its own speaker, microphone 3, and controller 4, etc., realizing diversified functions.

[0029] In this embodiment, both the cabinet body 1 and the upright panels 2 are made of wood, with an aesthetically pleasing and elegant appearance. To improve the connection between the two upright panels 2 and the cabinet body 1, please refer to the attached document. Figure 3A metal bracket 5 is connected to the rear end of the cabinet 1, and the upper surface of the metal bracket 5 is higher than the upper surface of the cabinet 1. The upper end of the metal bracket 5 is roughly level with the upper ends of the two uprights 2. The metal bracket 5 here is assembled and welded from two vertical columns and five horizontal bars. The outer walls of the two vertical columns are connected to vertically extending hinge assemblies. The rear sides of the two uprights 2 are respectively connected to the other side of the corresponding hinge assemblies. Due to structural limitations, the three horizontal bars in the middle are all connected to the rear uprights 2 of the cabinet 1 by at least two connecting screws. In this structure, the two upright panels 2 are rotatably connected to the metal bracket 5 via a hinge assembly. When the podium is in use, the front ends of the two upright panels 2 unfold outward to a set angle to maximize the usable area of ​​the podium. When the podium is not in use, the two upright panels 2 can be rotated inward for storage. To better achieve podium storage and further reduce the volume after storage, the platform is divided into a main platform 20 and two side platforms 21. The main platform 20 is fixedly connected to the upper end of the cabinet 1, and the two side platforms 21 can be folded up and down and connected to both sides of the main platform 20. When the two side platforms 21 are rotated open... When the two side panels 21 are on the same plane as the main platform 20, they form a complete podium panel structure. When in use, the ends of the two side panels 21 away from the main platform 20 are positioned with the two uprights 2 by positioning components to ensure the stability of the entire platform. When the podium needs to be stored, first release the connection limit between the two side panels 21 and the two uprights 2, open the two uprights 2 outward at a slight angle, then fold the two side panels 21 down to a vertical storage state, and then rotate the two uprights 2 inward to store them against the two side panels 21 to achieve the storage of the podium, which is very convenient.

[0030] Preferably, both upright panels 2 are inwardly curved arc panels, and the outer end faces of the corresponding two side panels 21 are arc surfaces that match the arc panels, thus enhancing the aesthetics of the entire podium.

[0031] In this embodiment, see Appendix Figure 2 The positioning components include a first connector 22 and a second connector 23. The first connector 22 is located on the lower end face of the side plate 21 away from the main plate 20, and a positioning slot 24 is provided on the first connector. The second connector 23 is located on the inner wall of the corresponding upright plate 2, and a positioning insert plate is provided on the second connector 23 to be inserted into the positioning slot 24. 25 In some other embodiments, the positioning slot 24 and the positioning insert plate structure can be interchanged. It can even be further simplified by simply opening the positioning slot 24 on the lower end face of the side plate 21 and providing the positioning insert plate on the second connector 23.

[0032] On the other hand, in this embodiment, see Appendix Figure 1 and 5The controller 4 includes a base plate 6, a front panel 7 that slopes vertically from back to front, and left and right side panels 8. A touchscreen display 9 is mounted on the front panel 7. Additionally, a power switch is located on the front panel 7 for turning the audio system on and off. An audio adjustment port is also located on the upright plate 2 of the controller 4.

[0033] Preferably, in the above structure, the left and right side panels 8 and the front panel 7 together form the housing structure of the controller 4, and the left and right side panels 8 are directly bent backward from both ends of the front panel 7. That is, the front panel 7 and the left and right side panels 8 are an integral structure, which eliminates the connection steps between them, reduces costs, ensures an integrated appearance, and improves aesthetics.

[0034] More specifically, in the above structure, participants in the appendix Figure 4 The lower ends of the left and right side panels 8 are bent inward to form a horizontal first connecting plate 11. The bottom plate 6 is connected to the top of the cabinet 1, and its left and right ends extend beyond the ends of the top plate of the cabinet to form a mounting skirt. Both mounting skirts are provided with connecting holes, and connecting screws for connecting to the first connecting plate 11 are inserted from bottom to top in each connecting hole.

[0035] For further details, please refer to the appendix. Figure 4 and 5 The rear ends of the left and right side plates 8 are bent inward to form a vertical second connecting plate 12, and the rear side walls of the two second connecting plates 12 are connected with horizontal screws 13. The front side walls of the left and right ends of the metal bracket 5 are provided with hoist hanging holes 14 with an upper width greater than the lower width. The screw heads of each horizontal screw 13 are respectively mounted and fitted in the corresponding hoist hanging holes 14.

[0036] On the other hand, see Appendix Figure 6 and 7 The upper ends of the left and right side plates 8 are provided with limiting holes 15, and the lower end surfaces of the left and right ends of the cover plate 10 are provided with downwardly extending limiting plates. The side walls of the two limiting plates are formed with limiting protrusions 16 for cooperating with the corresponding limiting holes 15.

[0037] In the above structure, when installing the controller 4, the base plate 6, pre-installed with relevant components, is connected to the top plate of the cabinet 1 with screws. Then, the cover, pre-installed with the corresponding components, is installed. During installation, the cover is first moved to the top of the base plate 6, and then slowly moved backward to ensure that the horizontal screws 13 at the rear end of the left upright plate 2 of the cover are aligned with the large holes of the gourd hanging holes 14 on the metal bracket 5. Next, the cover is moved downward so that the screw heads of each horizontal screw 13 engage and are limited in the small holes of the gourd hanging holes 14. Then, the operation is performed from below the two mounting skirts, tightening the connecting screws from bottom to top to connect and fix the lower ends of the left and right side plates 8 of the cover to the base plate 6. Finally, the cover plate 10 is installed, directly pressed from top to bottom until the limiting protrusions 16 on the two positioning plates engage with the two limiting through holes 15 for limiting. After installation, no fasteners are visible from the outside, effectively improving the overall aesthetic appearance of the lectern.

[0038] For the above structure, please continue to refer to the appendix. Figure 6 and 7 To further ensure the structural strength of the housing after connection and the stability of the cover plate 10 after closing, a rectangular fixing plate 17 is added to the top of the housing. The rear end of the fixing plate 17 is detachably connected to the top of the metal bracket 5 by screws, and the front end of the fixing plate 17 is detachably connected to the top of the front panel 7 by screws. A horizontal connecting plate is provided at the top of the front panel 7. The fixing plate 17 has four rectangularly distributed positioning holes 18. Four conical positioning posts 19 are formed protruding from the lower end face of the cover plate 10, which are inserted into the positioning holes 18. With this arrangement, when pressing the cover plate 10, the four conical positioning posts 19 are aligned with the four positioning holes 18 and pressed from top to bottom, which can better ensure that the limiting protrusion 16 and the limiting through hole 15 are accurately engaged, and the structure is more stable and firm after engagement.
