[0021] In one embodiment, the wire fixing part is provided with a wire fixing hole, the wire passes through the wire fixing hole, and the hole wall of the wire fixing hole clamps the part of the wire passing through the wire fixing hole.

[0022] In one embodiment, the wall of the wire hole near the wire fixing part is smoothly connected to the lower surface of the table body.

[0023] In one embodiment, the table is located above the cabinet, and the podium further includes:

[0024] The connection structure is used to connect the cabinet and the table. The cable fixing part is located on the top of the cabinet, and the counterweight moves between the cabinet and the table.

[0025] In one embodiment, the table is located above the cabinet, and the podium further includes:

[0026] The lifting mechanism is used to install in the cabinet.

[0031] A fastener, which connects to the interface end or slides onto the wire, is used to fix the device to the table or the device that is connected to the interface end when the interface end is connected.

[0032] Based on the above embodiments, this application provides a cable passage hole connecting the space beneath the table body. The connector end of the wire extends through the cable passage hole and rests on the desktop. A counterweight connects to the portion of the wire located beneath the table body. When the connector end needs to be connected to other devices, the wire can be pulled out, exposing more of the wire on the desktop for easy connection. When disconnecting the connector end from other devices, the wire is pulled back by the weight of the counterweight, reducing the area occupied by the wire on the desktop. Thus, while ensuring convenient wiring, the wire can retract into the space beneath the table body when not in use, reducing desktop space usage and making the desktop neater and more aesthetically pleasing. Compared to related technologies using spring-loaded wires, the technical solution of this application saves more desktop space, and the weight of the counterweight guides the wire retraction, preventing tangling between multiple wires. Furthermore, since the wire automatically retracts under the weight of the counterweight, no manual retraction is required, improving the ease of use of the podium and enhancing the user experience.

[0048] Nowadays, with the continuous advancement of technology, lecterns have gradually replaced traditional lecterns, and their functions have become increasingly diversified, enriching the presentation methods in teaching, lectures, and other scenarios. To achieve good audiovisual presentation effects, lecterns often also house electronic devices such as microphones and monitors. To facilitate signal interaction and power transmission between devices on the lectern and between the lectern and other devices, lecterns typically have multiple wires. In related technologies, the wiring harnesses of the lectern are often placed on the tabletop, making the desktop look cluttered and unsightly; even worse, some lecterns are equipped with spring wires, and multiple spring wires are prone to tangling, not only affecting aesthetics but also taking up considerable desktop space and potentially interfering with the normal use of the spring wires.

[0049] To solve the above problems, please refer to Figures 1 to 3 This application provides a lectern 1. The lectern 1 includes a platform and a telescopic cable structure 50.

[0050] The platform includes a cabinet 10 and a table 20 connected to the cabinet 10. The cabinet 10 is used to place the platform on a work platform, such as when it is installed on the ground. The cabinet 10 defines the general shape of the lectern 1 and also serves as the structural support for the entire lectern 1. The outer contour of the cabinet 10 can be a cuboid shape, which makes it easy to place the lectern 1 in the front position of, for example, a classroom or conference room, and to make reasonable use of the interior space of the classroom or conference room. Of course, the shape of the cabinet 10 can also be other, such as a cube, or a columnar body with a cross-section in the shape of a racetrack, an ellipse, etc., and this application does not make specific limitations in this regard.

[0051] In practical applications, the cabinet 10 can be used to house fixed electronic devices, such as computer hosts and switches. It should be noted that the cabinet 10 can be a closed structure or a frame structure, as long as it can accommodate fixed electronic devices. In the exemplary structure shown in the figure, the cabinet 10 consists of a supporting frame and multiple surrounding panels fixedly connected to the supporting frame. The cabinet 10 can also be equipped with an openable door 11, which can open by sliding or pivoting to facilitate the placement of electronic devices into the main body. Furthermore, considering heat dissipation requirements, this application can further provide ventilation holes on the bottom panel of the main body. The bottom of the main body is also connected to support legs 12, which raise the main body to allow airflow through the ventilation holes. It is understood that the support legs 12 can be fixed or movable, such as using casters; this application does not limit this.

[0052] In some embodiments, the table 20 is located above the cabinet 10, and the table 20 and the cabinet 10 can be directly and fixedly connected by a connecting structure. For example, the connecting structure can be a connecting column, with one end connected to the cabinet 10 and the other end connected to the table 20. The connecting column can be made of metal to ensure sufficient structural strength and stability. To further improve the stability of the table 20 and ensure a better user experience, the connecting structure can include two or more connecting columns, with at least two connecting columns arranged at intervals, to achieve multi-point support for the table 20, increase the contact area between the connecting structure and the table 20, thereby making the table 20 more evenly stressed and structurally more stable.

[0053] In some embodiments, the podium 1 also includes a lifting mechanism 40. The lifting mechanism 40 is installed in the cabinet 10, and its output end 41 is connected to the tabletop 21 to drive the tabletop 21 to move up and down along the height direction of the podium 1. This enables the tabletop 20 to change position in the height direction of the podium 1, so that the podium 1 is suitable for various working conditions and can accommodate users of different heights, thus improving the compatibility of the podium 1.

[0054] Regarding the specific structural form of the lifting mechanism 40, this application has various forms, including electric push rod, cylinder, and a combination of motor and transmission components. In one specific implementation, the lifting mechanism 40 includes a sleeve, a telescopic rod, and a lead screw assembly. The sleeve passes through a clearance hole and is fixedly connected to the cabinet 10. The telescopic rod is slidably nested within the sleeve and has an output end 41. The lead screw assembly is driven by the telescopic rod and is used to drive the telescopic rod to slide relative to the sleeve. It is understood that the lead screw assembly includes a motor, a lead screw nut, and a lead screw. The motor can be installed at the bottom of the sleeve and connected to the lead screw to drive the lead screw to rotate. The lead screw nut engages with the lead screw and is fixedly connected to the telescopic rod. During the rotation of the lead screw driven by the motor, the lead screw nut reciprocates along the length of the lead screw, causing the telescopic rod to slide relative to the sleeve to extend or retract, thereby achieving the lifting and lowering of the upper tabletop 21. When the lifting mechanism 40 adopts the above-described form, it features precise lifting.

[0055] Understandably, the above-mentioned lead screw assembly is one structural form that uses a motor and transmission components. Other forms of transmission components may include sprocket transmission structure, belt pulley transmission structure, gear and rack mesh structure, etc. This application does not limit these.

[0056] The table 20 is used to place electronic devices or related teaching demonstration tools. In this embodiment, the table 20 can be made of wood or metal, etc. Figure 3 and Figure 4 As shown, the table body 20 is provided with a cable passage hole 211, which connects to the space below the table body 20. Optionally, the space below the table body 20 corresponding to the cable passage hole 211 can be the space inside the cabinet 10 or the space on one side of the cabinet 10. The telescopic cable structure 50 includes a wire 51 and a counterweight 52. One end of the wire 51 is connected to the cabinet 10, and the other end is an interface end 511. The portion between the two ends of the wire 51 is located in the space below the table body 20. The interface end 511 extends out of the cable passage hole 211 and is located on the table body 20 for connection to electronic devices such as microphones and monitors. The counterweight 52 connects to the portion of the wire 51 located below the table body 20.

[0057] In this embodiment, the interface 511 can be an HDMI (High Definition Multimedia Interface) interface, a DP (DisplayPort) interface, etc., for transmitting video signals, or a USB (Universal Serial Bus) interface, etc., for transmitting data information. The end of the wire 51 away from the interface 511 can be electrically connected to the cabinet 10. In this case, this end of the wire 51 can also have an HDMI interface, a DP interface, or a USB interface, etc.; the end of the wire 51 away from the interface 511 can be simply physically connected to the cabinet 10, with the cabinet 10 providing one of the physical bases for fixing the wire 51.

[0058] Understandably, the diameter of the through hole 211 is larger than the outer diameter of the wire 51, so that the wire 51 can move within the through hole 211, allowing the interface end 511 to movably pass through the through hole 211. The shape of the through hole 211 can be circular, square, or oval, etc., and this embodiment does not limit this. Please refer again to... Figure 3 , Figure 4 In the diagram, the solid line represents the position of the wire 51 when it extends out of the wire hole 211, while the dashed line represents the position of the wire 51 when it retracts. When the wire 51 is not in use, i.e., when it does not need to connect to electronic equipment, most of the wire 51 is located in the space under the table under the weight of the counterweight 52, with only the interface end 511 remaining outside the wire hole 211 and exposed on the table. When it is necessary to connect the interface end 511 to electronic equipment, the weight of the counterweight 52 can be easily overcome by pulling the interface end 511, allowing the portion of the wire 51 located under the table to pass through the wire hole 211, making it easy to pull the interface end 511 near the electronic equipment for interface docking. After use, disconnect the interface 511 from the electronic device. Since there is no constraint from the interface of the electronic device, that is, when there is no external force pulling the wire 51, the counterweight 52 falls due to its own weight. Under the action of its own weight, it simultaneously drives the wire 51 out of the wire hole 211 and into the space under the table 20. This is a phenomenon in which the wire 51 retracts and the interface 511 moves towards the direction close to the wire hole 211 until it returns to the aforementioned state where the wire 51 was not used, thus realizing the recovery of the wire 51.

[0059] In this embodiment, a cable hole 211 is provided in the table body 20 to connect to the space below the table body 20. The interface end 511 of the wire 51 moves out through the cable hole 211 and is located on the desktop. The counterweight 52 connects the part of the wire 51 located below the table body 20. When the interface end 511 needs to be connected to other devices, the wire 51 can be pulled out, making more of the wire 51 exposed on the desktop for easy device connection. When disconnecting the interface end 511 from other devices, the wire 51 is pulled back by the weight of the counterweight 52, realizing the recycling of the wire 51 and reducing the area occupied by the wire 51 on the desktop. In this way, while ensuring the convenience of wiring, the wire 51 can be retracted into the space below the table body 20 when not in use, reducing the occupation of desktop space and making the desktop neater and more aesthetically pleasing. Compared with the technical solution using spring wire in related technologies, the technical solution of this embodiment saves desktop space, and the self-weight of the counterweight 52 guides the recycling of the wire 51, avoiding the situation where multiple wires 51 are easily tangled. In addition, since the wire 51 can automatically retract under the weight of the counterweight 52, there is no need for manual winding and other operations, which improves the ease of use of the podium 1 and enhances the user experience.

[0060] Please combine Figure 4 and Figure 5 In some embodiments, the podium 1 further includes a junction box 30, which is mounted on the table body 20. Optionally, the junction box 30 is a shell-like structure with an open bottom, covering the area of ​​the table body 20 where the wire hole 211 is provided, thereby defining a receiving cavity 32 with the table body 20, and the wire hole 211 communicates with the receiving cavity 32. The junction box 30 also has an outlet hole 315 communicating with the receiving cavity 32, with part of the wire 51 located inside the receiving cavity 32, and the interface end 511 passing through the outlet hole 315. By providing the junction box 30, the wire hole 211 on the table can be blocked, and when there are many wires 51, the wires 51 can be covered, further improving the neatness of the podium 1.

[0061] Optionally, the cable outlet 315 is higher than the desktop of the table body 20. As the cable 51 moves through the cable outlet 315, it is raised by the wall of the cable outlet 315. During the movement, the contact area between the cable 51 and the table body 20 is reduced, and the friction between the two is reduced, so that the movement of pulling out the cable 51 and retracting the cable 51 is smoother.

[0062] In some structural configurations, the table body 20 is surrounded by a barrier 23, and the electrical box 30 is positioned close to the barrier 23. This avoids the electrical box 30 occupying the space in the middle of the table body 20 and improves the utilization rate of the desktop.

[0063] In some embodiments, the power box 30 includes a box body 31 and a power socket 33. The box body 31 is connected to the table body 20 and defines the aforementioned receiving cavity 32 with the table body 20. The power socket 33 is connected to the box body 31 and is arranged side by side with the wire 51 along one side of the table body 20. The power socket 33 serves as a power supply extension for the lectern 1, allowing users to directly connect devices such as chargers through the power socket 33, which facilitates user use and enriches the functionality of the lectern 1.

[0064] like Figure 4 As shown, the box body 31 is composed of multiple interconnected panels. Using the side of the podium 1 closest to the user as the front and the side furthest from the user as the rear, the box body 31 includes a front panel 311, a top panel 312, a rear panel 314, and two side panels 313. The front panel 311 and rear panel 314 are spaced apart and both are connected to the top panel 312. The top panel 312 faces the tabletop of the table body 20. The two side panels 313 are connected to the left and right ends of the front panel 311, rear panel 314, and top panel 312. Two or more of the front panel 311, top panel 312, rear panel 314, and two side panels 313 can be a single integrated structure. For example, to improve aesthetics, the front panel 311 and top panel 312 can be constructed as a single unit, with a curved transition between them. The front panel 311 can also be further inclined to achieve a smooth transition from the front panel 311 to the enclosure 23, enhancing the overall unity of the podium 1. Of course, the front panel 311, top panel 312, rear panel 314, and two side panels 313 can also be manufactured independently and connected together by snap-fit, screw connection, or adhesive bonding. Understandably, the connection between the box body 31 and the table body 20 can also be achieved by snap-fit, screw connection, or adhesive bonding, and no limitation is made here.

[0065] In one embodiment, the power socket 33 is connected to the top plate 312 for easy insertion. A wire outlet 315 is located on the front panel 311, allowing the wire 51 to extend directly to the front of the housing 31, facilitating the connection of the interface end 511. The diameter of the wire outlet 315 is larger than the outer diameter of the wire 51, and the shape of the wire outlet 315 can be circular, square, or oval, etc., which is not limited in this embodiment. After the wire 51 is retracted, the interface end 511 of the wire 51 is exposed from the front of the housing 31, rather than extending to other sides of the housing 31, thus avoiding an overly protruding interface end 511. Of course, the power socket 33 can also be detached from the housing 31 and disposed outside the housing 31 along with the interface end 511, which is not limited in this embodiment.

[0066] Since the central axis of the cable guide hole 211 extends approximately along the height direction (vertical direction) of the podium 1, while the central axis of the cable exit hole 315 extends approximately along the front-back direction of the podium 1, the cable 51 needs to be bent at a certain angle after passing through the cable guide hole 211 and then through the cable exit hole 315. If the bending angle of the cable 51 is too large, the cable 51 will experience excessive friction with the table body 20 around the cable guide hole 211 during movement, which may lead to uneven movement of the cable 51 and potential wear after prolonged use. Therefore, please consider the following: Figures 5 to 7 In one embodiment, the podium 1 further includes a conduit 34, which is disposed within the receiving cavity 32 and defines a wire channel 341 connecting the wire outlet 315 and the wire through hole 211. The wire 51 passes through the wire channel 341. The conduit 34 is curved in an arc shape, so that the portion of the wire 51 passing through it does not contact the tabletop 21 around the wire through hole 211 during movement. The conduit 34 guides the wire 51 to bend in a relatively gentle manner, making the movement of the wire 51 smoother and preventing wear on the wire 51, thus extending the service life of the wire 51.

[0067] In another embodiment, a wire groove can be provided on the table body 20 around the wire hole 211. Specifically, the wire groove can be provided on the side of the wire hole 211 near the wire outlet hole 315. The wire groove extends between the wire hole 211 and the wire outlet hole 315, and the bottom wall of the wire groove is curved or inclined relative to the table surface, so as to realize the transition between the table surface of the table body 20 and the wall of the wire outlet hole 315, increase the contact area between the wire 51 and the table body 20, avoid the wire 51 being subjected to concentrated force, guide the movement of the wire 51, and prevent the wire 51 from getting stuck.

[0068] To prevent the interface end 511 from falling back, in one embodiment, a limiting member is provided at the outlet hole 315. The limiting member blocks the outlet hole 315 to prevent the interface end 511 from moving through the outlet hole 315. Exemplarily, the limiting member includes a brush member mounted on the junction box 30. The brush member can be mounted on the front panel 311 of the box body 31, such as on the front wall of the front panel 311 or on the wall of the outlet hole 315. The brush member has bristles extending radially along the outlet hole 315, which block the outlet hole 315. Under the action of external force during wire threading, the wire 51 can deform the bristles and freely pass through the outlet hole 315. By setting the density, length, and hardness of the bristles, and by making the size of the interface end 511 larger than the size of other parts of the wire 51, the bristles can block the interface end 511 when the wire 51 retracts, preventing the interface end 511 from retracting along with the other parts of the wire 51 as it passes through the outlet hole 315. This effectively avoids repeatedly pulling the interface end 511 out of the cable outlet 315, making it easier for users to operate and improving the user experience. In addition, the brush component can also prevent foreign objects from entering the receiving cavity 32 or the space under the table body 20 through the cable outlet 315, ensuring the cleanliness of the inside of the podium 1 and the normal use of the podium 1.

[0069] Alternatively, the limiting member can also be in the form of a limiting plate, with the interface end 511 connected to the limiting plate. When the wire 51 retracts until the limiting plate abuts against the front panel 311 outside the wire outlet hole 315, the interface end 511 is kept outside the wire outlet hole 315.

[0070] Furthermore, the telescopic cable structure 50 also includes a fixing member (not shown), which can be a connecting interface end 511 for fixing to the table body 20 or the device that interfaces with the interface end 511 when connecting to other devices. In some embodiments, a limiting structure that can cooperate with the fixing member is provided in a commonly used area on the desktop of the table body 20, wherein the commonly used area can be understood as the area on the desktop that is commonly used to place electronic devices. When the interface end 511 is connected to an electronic device, the fixing member can also cooperate with the limiting structure, thereby fixing the cable 51 relative to the electronic device, preventing the cable 51 from pulling on the interface end 511 and causing the interface end 511 to loosen, and improving the stability of the interface connection; in addition, the above solution can also reduce the force on the interface end 511 when it is connected to the relevant interface of the electronic device, and avoid interface damage. Of course, fixing the interface 511 to the commonly used area of ​​the table 20 with the fastener also makes it easier for users to switch the device connected to the interface 511 or pause the connection between the interface 511 and the device, avoiding repeated stretching and contraction of the wire 51 and preventing users from frequently pulling the wire 51. This not only improves the lifespan of the wire 51, but also enhances the ease of use.

[0071] For example, when the material of the table body 20 or the device that connects to the interface end 511 is iron, the fastener can be a magnetic component and fixed by magnetic attraction; when the material of the table body 20 or the device that connects to the interface end 511 is a non-magnetic material, such as when the table body 20 is made of wood, the fastener can also be a suction cup and fixed by negative pressure adsorption.

[0072] In addition to being installed at the interface end 511, the fastener can also be slidably sleeved on other parts of the wire 51 so that the position of the fastener can be freely adjusted to fix other parts of the wire 51 relative to the table body 20. This will not be elaborated further here.

[0073] Please refer to Figure 6 and Figure 7 In some embodiments, a wire fixing part 221 is provided below the table body 20. Specifically, the table body 20 includes a tabletop 21 and a support 22. The support 22 may be made of metal and constructed as a frame structure to improve the structural strength of the support 22. The support 22 is connected to a connecting structure or a lifting mechanism 40. The tabletop 21 is positioned above the support 22 and has a wire passage hole 211. The support 22 includes a crossbeam, and the wire fixing part 221 is disposed on the crossbeam. Optionally, the wire fixing part 221 has a wire fixing hole, through which the wire 51 passes. The wall of the wire fixing hole clamps the portion of the wire 51 passing through the wire fixing hole, so that the wire 51 is connected to the wire fixing part 221. A counterweight 52 is connected to the portion of the wire 51 between the wire fixing part 221 and the interface end 511.

[0074] Optionally, the wire fixing part 221 is located on the side of the wire passage hole 211 away from the wire outlet hole 315. This reduces the bending of the wire 51 and minimizes the contact between the wire 51 and the wall of the wire passage hole 211 during its movement, thus improving the smoothness of the wire 51's movement. Furthermore, the wall of the wire passage hole 211 near the wire fixing part 221 smoothly transitions to the lower surface of the table body 20. For example, the two can use an arc-shaped surface for the transition. This prevents the junction between the wall of the wire passage hole 211 and the lower surface of the table body 20 from being too sharp and scratching the wire 51, thereby effectively protecting the wire 51 and extending its service life.

[0075] The cable fixing part 221 is located above the cabinet 10. The length of the wire 51 portion between the cable fixing part 221 and the interface end 511 is greater than the distance between the cable fixing part 221 and the cable passage hole 211 (cable outlet hole 315). The counterweight 52 is disposed on the wire 51 portion between the cable fixing part 211 and the interface end 511. This ensures that the portion of the wire 51 that extends or retracts relative to the cable passage hole 211 (cable outlet hole 315) is always the portion of the wire 51 that has passed through the cable fixing hole. In this way, on the one hand, the impact of the extension or retraction of the wire 51 on the portion of the wire 51 before passing through the cable fixing hole can be reduced, improving the stability of the connection between the wire 51 and the cabinet 10. On the other hand, it can also keep the counterweight 52 moving between the cabinet 10 and the table 20, avoiding the counterweight 52 colliding with the cabinet 10 and generating noise.

[0076] In the embodiment where the cabinet 10 and the desk 20 are connected via the lifting mechanism 40, the portion of the wire 51 between the end connected to the cabinet 10 and the fixing part 221 has sufficient length redundancy. Understandably, when the desk 20 is raised or lowered relative to the cabinet 10, the portion of the wire 51 between the end connected to the cabinet 10 and the fixing part 221 moves accordingly, ensuring that the redundancy of the wire 51 meets the maximum lifting height of the desk 20 by the lifting mechanism 40. Therefore, by providing the fixing part 221, it can be ensured that the raising and lowering movement of the desk 20 does not affect the portion of the wire 51 between the interface end 511 and the fixing part 221, avoiding pulling on the wire 51, thereby ensuring the normal extension and retraction operation of the wire 51 through the cable hole 211.

[0077] In some embodiments, the telescopic cable structure 50 includes a plurality of wires 51 and a plurality of counterweights 52. The plurality of wires 51 are connected to the plurality of counterweights 52 in a one-to-one correspondence. The table body 20 is provided with a plurality of wire holes 211. The plurality of wires 51 are correspondingly passed through the plurality of wire holes 211, so as to satisfy the rich expandability and functionality of the podium 1 through the plurality of wires 51, while avoiding mutual interference of the plurality of wires 51 and avoiding the wires 51 from getting tangled.

[0078] In this embodiment, the counterweight 52 can be a lead weight. The counterweight 52 is detachably connected to the wire 51, allowing for the tailoring of different counterweights 52 for different wires 51. Understandably, different wires 51 have varying flexibility and weight. For some wires 51, a lead weight of approximately 100g is sufficient to pull them, while for others, a lead weight of 300g or 400g may be required to ensure proper retraction. The counterweight 52 and the wire 51 can be detachably connected using a clamping connection or a fastener connection for easy adjustment.

[0079] To prevent multiple counterweights 52 from colliding with each other, the podium 1 is also equipped with multiple partitions, with at least one partition between two connected counterweights 52. Optionally, the partitions are set on the crossbeam and extend along the height direction of the podium 1 to effectively prevent the counterweights 52 from colliding with other counterweights 52 during their up-and-down movement, reduce noise, and ensure the normal extension and retraction of the conductors 51.
