Description

Technical Field

[0001] The utility model belongs to the technical field of lecterns, and particularly relates to a lifting multifunctional lectern with a rapid heat dissipation structure. Background Art

[0002] With the development of multimedia technology, the functions of lecterns have no longer been limited to traditional podiums, but have gradually evolved into speech devices integrating multiple functions. Existing lecterns are usually equipped with electronic devices such as computer hosts, display screens, and power supplies. These devices generate a large amount of heat during operation.

[0003] However, the existing lectern designs often neglect the heat dissipation problem of internal electronic devices. If the heat dissipation is not timely or the heat dissipation efficiency is low, it will not only affect the performance and lifespan of each electronic device, but may also cause damage to the structure of the lectern and even pose potential safety hazards. For example, in the prior art, a Chinese patent with the publication number CN201624302U discloses a multifunctional podium. Rotating brackets are provided on both sides of its display panel. Each bracket includes two clamping plates connected movably. Semi-circular grooves corresponding to each other are formed on each clamping plate. The circular hole formed by the two grooves is sleeved with a fixed shaft; rotating shafts are provided on the lower sides of its central control box, and the rotating shafts are inserted into corresponding jacks to form a rotating central control box.

[0004] The above prior art improves the fixed panel to a rotating panel by setting a rotating mechanism connecting the display panel, enabling it to rotate at any angle and quickly position, so as to achieve the best viewing angle effect. However, the above prior art does not set a corresponding heat dissipation structure, resulting in poor heat dissipation effect; moreover, the use environment of this multifunctional podium is relatively enclosed, further exacerbating the heat dissipation difficulty.

[0005] In addition, most existing lecterns have a single function and lack necessary adaptability designs, such as a lifting function. This causes existing lecterns to be unable to adapt to the different heights of different speakers, thereby affecting the comfort and visual effect of speakers when using the lectern for a speech. For example, a Chinese patent with the publication number CN2652224Y discloses a multifunctional lectern. Although this lectern integrates functions of sound pickup and broadcasting, it is fully functional and easy to use. However, this prior art lacks a lifting function and cannot adapt to the height differences of different speakers, thus limiting its adaptability in practical applications. For example, when the speaker is relatively tall, due to the relatively long distance from the tabletop, the speaker may not be able to clearly view the reminder script on the tabletop; when the fixed position of the microphone on the tabletop is relatively high or low, the staff needs to manually adjust the height of the microphone according to the height of each speaker to meet the needs of different speakers, resulting in an increased workload and also reducing the usability of the lectern.

[0006] Therefore, there is an urgent need for a lifting multifunctional lectern with a fast heat dissipation structure to effectively solve the heat dissipation problem of the existing lectern and improve the usability and adaptability of the lectern. Summary of the Invention

[0043] Such as Figure 1-8As shown in the figure, this embodiment provides a lift - type multifunctional lectern with a fast - heat - dissipation structure, including a lectern main body. The lectern main body includes a base 1, a lift table 2, and a display module 3. A lift structure is provided inside the base 1, and the movable end of the lift structure is connected to the lift table 2, thereby enabling the lift table 2 to be movably connected above the base 1. The display module 3 is installed on the lift table 2.

[0044] The lift table 2 includes an outer cabinet 6. There is an electrical cavity 61 inside the outer cabinet 6. A window communicating with the electrical cavity 61 is provided on one side of the outer cabinet 6. The display module 3 is installed on the window, and the front of the display module 3 is exposed outward through the window to display information. At least two radiators 7 are provided inside the electrical cavity 61, and the two radiators 7 are symmetrically arranged.

[0045] Each radiator 7 includes a heat - conducting plate 71, a first transition plate 72, and a heat - dissipating plate 73 that are connected in sequence. One side of the heat - conducting plate 71 is attached to the surface of the display module 3, and one side of the heat - dissipating plate 73 is attached to the inner side wall of the outer cabinet 6. A number of heat - dissipation holes 721 are provided on the first transition plate 72.

[0046] A cross - plate 21 is also provided inside the electrical cavity 61. The movable end of the lift structure abuts against the cross - plate 21. The lift structure drives the lift table 2 to move up and down reciprocally relative to the base 1.

[0047] In this embodiment, the display module 3 can expand the heat - dissipation area through the radiator 7 to promote heat dissipation. Moreover, in the radiator 7, the heat - conducting plate 71 is the first - layer heat dissipation, the first transition plate 72 is the second - layer heat dissipation, and the heat - dissipating plate 73 is the third - layer heat dissipation. The design of the radiator 7 enables the display module 3 to conduct and dissipate heat layer by layer, thereby conducting the heat of the display module 3 to the side walls of the electrical cavity 61 and the outer cabinet 6, further improving the heat - dissipation efficiency.

[0048] In addition, the lift structure drives the lift table 2 to move up and down reciprocally relative to the base 1, making the lift - type multifunctional lectern described in this embodiment have a lifting function. Without the need for staff to laboriously adjust the height of the microphone 85, it can adapt to the heights of different speakers, thereby improving the adaptability and use convenience of the lift - type multifunctional lectern described in this embodiment.

[0049] Specifically, the heat - conducting plate 71 and the heat - dissipating plate 73 are perpendicular to each other, and the first transition plate 72 extends obliquely from one side of the heat - conducting plate 71 to the heat - dissipating plate 73.

[0050] The length of one side of the first transition plate 72 connected to the heat conducting plate 71 is less than the length of the side of the first transition plate 72 connected to the heat dissipating plate 73;

[0051] Specifically, a plurality of the heat dissipation holes 721 penetrate through the surface of the first transition plate 72;

[0052] In this embodiment, the heat dissipation holes 721 penetrate through the surface of the first transition plate 72, providing a direct channel for heat to transfer from the first transition plate 72 to the electrical cavity 61, significantly improving the heat dissipation speed;

[0053] Specifically, each of the heat dissipation holes 721 is in a long strip shape; it should be noted that in this embodiment, the shape of each of the heat dissipation holes 721 is not limited to a long strip shape and can also be designed in other shapes; however, the long strip shape design in this embodiment can increase the air circulation area of the heat dissipation holes 721, helping to more effectively take away heat, reduce the temperature of the first transition plate 72, and achieve a gradual temperature decrease layer by layer;

[0054] Specifically, on the first transition plate 72, the heat dissipation holes 721 are radially distributed from the side of the first transition plate 72 connected to the heat conducting plate 71 to the other side, enabling heat to quickly and evenly diffuse from one side of the first transition plate 72 to the other side, avoiding the problem of local overheating.

[0055] Specifically, the display module 3 includes a display screen 31 and a main control board disposed on the back of the display screen 31; the main control board is disposed in a heat dissipation housing 32, and a plurality of heat dissipation through holes 321 are provided on the upper side, lower side, and right side of the heat dissipation housing 32;

[0056] The heat conducting plate 71 includes a first surface and a second surface arranged opposite to each other. The back surface of the heat dissipation housing 32 is completely and fittingly connected to the first surface, and the second surface faces the electrical cavity 61;

[0057] The heat dissipating plate 73 includes a third surface and a fourth surface arranged opposite to each other. The third surface is completely and fittingly connected to the inner side wall of the outer cabinet 6, and the fourth surface faces the electrical cavity 61;

[0058] Each of the radiators 7 is made of aluminum or aluminum alloy;

[0059] In this embodiment, the heat dissipation method of face-to-face fitting is beneficial to expanding the heat dissipation area, further promoting the layer-by-layer heat dissipation of the radiator 7, and improving the heat dissipation efficiency; at the same time, aluminum or aluminum alloy has better heat conduction effect, and each of the radiators 7 is made of aluminum or aluminum alloy, which is beneficial to further improving the heat conduction and heat dissipation efficiency.

[0060] Specifically, the base 1 includes a base cabinet 11 which is hollow and has an upward opening; a baffle 22 is provided at the bottom of the cross plate 21, and the baffle 22 is perpendicular to the cross plate 21 and extends downward into the base cabinet 11; the length of the baffle 22 does not exceed the inner depth of the base cabinet 11.

[0061] When the lifting platform 2 rises, the baffle 22 is used to block and protect the lifting structure, which can not only improve the aesthetics but also prevent interference from the external environment to the lifting structure.

[0062] Specifically, the inner side wall of the outer cabinet 6 is sleeved with the outer side wall of the base cabinet 11 to form a sliding contact, making the lifting of the outer cabinet 6 more stable and accurate in direction.

[0063] Specifically, the lifting structure in this embodiment is an electric push rod. The bottom platform 4 of the electric push rod is fixedly installed on the top surface of the base 1 and is located inside the base cabinet 11. The top end of the movable rod 5 of the electric push rod is connected to the bottom end of the cross plate 21, and the length direction of the movable rod 5 is perpendicular to the cross plate 21.

[0064] The design of the electric push rod enables the lifting platform 2 to have the function of moving up and down, and at the same time further improves the adaptability and use convenience of the liftable multi-functional lectern in this embodiment.

[0065] As Figure 1 shown, a door 62 is provided on the side of the outer cabinet 6 opposite to the window, and the door 62 extends from the cross plate 21 to the top of the outer cabinet 6; a lifting control button 621 is provided on the door 62, and the lifting control button 621 is electrically connected to the lifting structure. The lifting control button 621 controls the movement or stop of the lifting platform 2 by turning on and off.

[0066] The design of the lifting control button 621 makes the lifting control of the lifting platform 2 more convenient. Compared with the lecterns in the prior art, this embodiment does not require manual labor to adjust the height, reducing the workload of the staff and making the liftable multi-functional lectern in this embodiment more intelligent.

[0067] Specifically, the numerical range of the maximum upward movement stroke of the lifting platform 2 relative to the base 1 is 200 - 300 mm.

[0068] In this embodiment, the maximum upward movement stroke of the lifting platform 2 relative to the base 1 is preferably 250 mm, enabling the liftable multi-functional lectern to better meet the needs of speakers of different heights.

[0069] As Figures 3-4As shown in the figure, it further includes a table 8, and the table 8 includes a panel 81, an intermediate plate 82, a second transition plate 83, and an irregular boss 84 that are sequentially joined together from top to bottom; the irregular boss 84 is inclined towards the speaker;

[0070] The inclined setting is more conducive to the speaker to view the speech script and improves the adaptability of the liftable multi-functional lectern described in this embodiment.

[0071] As Figure 2 shown in the figure, one side edge of the intermediate plate 82 is provided with a first baffle 821 extending upward; one side edge of the panel 81 protrudes with a second baffle 811, and the other side edge is covered by the first baffle 821; the first baffle 821 and the second baffle 811 are respectively arranged on opposite sides of the table 8;

[0072] It should be noted that the upward protruding parts of the first baffle 821 and the second baffle 811 are both in arc transition, so that the first baffle 821 and the second baffle 811 can not only prevent items such as speech scripts from slipping, but also prevent the speaker from being injured due to bumping into the first baffle 821 and the second baffle 811, improving the usability and safety.

[0073] As Figure 1 shown in the figure, a microphone 85, a reading lamp 86, and a power socket 87 are provided on the table 8; the base 1 is provided with an audio output interface 111, and the audio output interface 111 is connected to the microphone 85 through an audio cable; the base 1 is also provided with a power interface 112;

[0074] The designs such as the microphone 85, the reading lamp 86, and the power socket 87 make the liftable multi-functional lectern described in this embodiment have more functions, be more user-friendly, and be more conducive to enhancing the user's usage experience.

[0075] As Figures 3-5 shown in the figure, the usage process of a liftable multi-functional lectern with a fast heat dissipation structure described in this embodiment is as follows:

[0076] When the lift table 2 needs to adjust its height, the user presses the lift control button 621, and the movable rod 5 of the electric push rod starts to drive the cross plate 21 to rise or fall along with the movable rod 5. When the user releases the lift control button 621, the electric push rod stops working, and the movable rod 5, the cross plate 21, and the lift table 2 stop moving.

[0077] When the display screen 31 is working, a part of the heat generated by the main control board is led out to the electrical cavity 61 through the heat dissipation through hole 321, and another part of the heat is conducted to the heat conduction plate 71. A part of the heat on the heat conduction plate 71 is dissipated to the electrical cavity 61 through the second surface, and another part of the heat is conducted to the first transition plate 72. A part of the heat of the first transition plate 72 is directly or indirectly dissipated to the electrical cavity 61 through the heat dissipation hole 721, and another part of the heat is conducted to the heat dissipation plate 73. The heat dissipation plate 73 conducts most of the heat to the inner side wall of the outer cabinet 6 through the third surface; the remaining heat on the heat dissipation plate 73 is dissipated to the electrical cavity 61 through the fourth surface.

[0078] According to the disclosure and teachings of the above specification, those skilled in the art to which the present utility model pertains can also make changes and modifications to the above embodiments. Therefore, the present utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present utility model should also fall within the protection scope of the claims of the present utility model. In addition, although some specific terms are used in this specification, these terms are only for convenience of description and do not constitute any limitation to the present utility model.
