[0042] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0043] In this application, the terms "first", "second", etc. are used to distinguish identical or similar items with substantially the same effects and functions. It should be understood that there is no logical or temporal dependency between "first", "second", and "nth", nor is there any limitation on the quantity and execution order.

[0044] With the continuous improvement of science and technology, lifting podiums have gradually replaced traditional desks. The lifting podium drives the table top to rise and fall by designing a lifting structure, so that the height of the podium can adapt to users of different heights. Lifting podiums are often used in classrooms, conference rooms, etc. The podium can be used by teachers, speakers, etc. The podium usually also carries some electronic equipment, such as microphones, monitors, etc. In addition, during the lecture, teachers need to prepare handouts, textbooks and other books and materials. Usually, for convenience, these books and materials are placed on the podium, and teachers also carry personal items. The lifting podium is set in the form of a table, and the electronic equipment has already occupied a certain space on the table. These books and materials and personal items will be placed together with the electronic equipment, which may limit the placement space of the podium.

[0045] To address the limited space available for a podium, some solutions consider combining storage cabinets with a lift-type podium. For example, to ensure a seamless installation of the podium and storage cabinets, the storage cabinets are placed inside the lift-type podium. However, to meet the needs of intelligent classrooms, lift-type podiums often house computer hosts and central control platforms. This means that the space available for storage cabinets within the lift-type podium is very limited. Therefore, the current approach of adding storage cabinets to traditional lift-type podiums is not an effective solution to the limited space available for the podium.

[0046] In order to solve the above problems, the present application proposes a lifting platform that can adjust the placement space and improve the placement effect of the lifting platform.

[0047] Please refer to FIG. 1 to FIG. 3 . In the embodiment of the present application, the lifting platform 1 includes a cabinet 10 , an upper table top 20 and a lifting mechanism 40 .

[0048] The cabinet 10 includes a main body 11 and a lower table top 12 arranged on the top of the main body 11. The cabinet 10 defines the general shape of the lifting platform 1 and also serves as a support for the entire lifting platform 1. The outline of the cabinet 10 can be a rectangular parallelepiped, which makes it easy to place the lifting platform 1 in the front position of a classroom or conference room, for example, and makes rational use of the interior space of the classroom or conference room. Of course, the outer shape of the cabinet 10 can also be other, such as a cube, or a columnar body with a runway-shaped, elliptical, or other cross-section, etc., which is not specifically described in this application.

[0049] In actual application, the main body 11 can be used to carry fixed electronic equipment, such as computer hosts, switches, central control platforms, etc. Of course, in the present application, the lifting platform 1 is used in ordinary classrooms, where there are not many electronic devices, or the fixed electronic equipment in the classroom has been installed outside the lifting platform 1. At this time, the main body 11 can also be used to store other items, such as teaching aids, daily necessities, etc., that is, the main body 11 can also be used as a locker. In some other usage scenarios, the present application can also partition the internal space of the main body 11, and some areas in the main body 11 are used to carry fixed electronic equipment, while other areas are used to store other items, that is, the main body 11 can have multiple functions of carrying fixed electronic equipment and storing other items at the same time, and the present application does not impose any restrictions on this.

[0050] It should be noted here that the main body 11 can be made into a closed structure or a frame structure, as long as it can accommodate fixed electronic equipment. In the structural form exemplified in the figure, the main body 11 is generally in the shape of a rectangular parallelepiped, which is composed of a support frame and a plurality of panels 111 arranged outside the support frame and fixedly connected to the support frame, wherein the lower table board 12 is covered on the upper ends of the plurality of panels 111. It can be understood that the lower table board 12 can also be a part of the panels 111 in the main body 11, that is, the upper end of the structure formed by the plurality of panels 111 of the main body 11 is open, and the lower table board 12 is sealed at the opening. Of course, the main body 11 may be enclosed to form a relatively closed space, and the lower table top 12 may be mounted on the enclosure 111 at the top of the main body 11, that is, the downward projection of the lower table top 12 of the present application may be of the same area as the downward projection of the main body 11, or the downward projection area of ​​the lower table top 12 may be larger than the downward projection area of ​​the main body 11, that is, the edge position of the lower table top 12 may extend outside the main body 11.

[0051] The main body 11 may also be provided with a door body 112 that can be opened and closed. The door body 112 may be opened by sliding and pushing or by pivoting, so as to facilitate the placement of electronic equipment in the main body 11. Furthermore, considering the heat dissipation requirements, the present application may further provide heat dissipation holes 114 on the enclosure 111 at the bottom of the main body 11 (refer to FIG2 ). Of course, the bottom of the main body 11 is also connected to a support leg 113, which raises the main body 11 so that air can flow through the heat dissipation holes 114 at the bottom. It is understandable that the support leg 113 may be fixed or movable, such as in the form of a universal wheel, and the present application does not impose any restrictions on this.

[0052] In other embodiments, the heat dissipation holes 114 may also be provided on the door body 112 (see FIG13 ). Of course, the heat dissipation holes 114 may also be provided on the enclosure 111 forming the side wall of the main body 11, or both the enclosure 111 and the door body 112 may have heat dissipation holes 114 to improve the heat dissipation efficiency.

[0053] The upper table top 20 is arranged above the lower table top 12, and the upper table top 20 and the lower table top 12 are separated to form a storage space 1a, and the lifting mechanism 40 is installed on the cabinet 10, and the output end of the lifting mechanism 40 is connected to the upper table top 20 to support the upper table top 20 above the lower table top 12; wherein, the lifting mechanism 40 can drive the upper table top 20 and drive the enclosure assembly 30 to move in the height direction so as to adjust the spatial height of the storage space.

[0054] In one embodiment, the lifting platform 1 may further include an enclosure assembly 30, which is connected to the upper table top 20 and is arranged around the outside of the cabinet 10, wherein the enclosure assembly 30, the upper table top 20 and the lower table top 12 cooperate to form the above-mentioned storage space 1a. It can be understood that the storage space 1a of the present application can also be formed by the upper table top 20 and the lower table top 12 without the enclosure assembly 30. When the enclosure assembly 30 also participates in the formation of the storage space 1a, the items in the storage space 1a can be hidden from the outside, and the privacy is better. In addition, by setting the enclosure assembly 30 at the front side, the items in the storage space 1a can be effectively prevented from falling toward the front.

[0055] In this embodiment, the area of ​​the upper table top 20 can be slightly larger than the area of ​​the lower table top 12. In this way, after the enclosure assembly 30 is directly connected to the upper table top 20, there is a certain distance between the enclosure assembly 30 and the cabinet 10 to ensure that the enclosure assembly 30 does not interfere with the main body 11 during movement. Of course, the downward projection area of ​​the upper table top 20 can also be equivalent to the area of ​​the lower table top 12. The enclosure assembly 30 and the upper table top 20 are connected by a connecting structure to ensure a movement gap. The enclosure assembly 30 of the present application is mainly used to cooperate with the upper table top 20 to facilitate the placement of items. In one structural form, the upper part of the enclosure assembly 30 protrudes above the upper table top 20. In this way, after being placed on the upper table top 20, on the one hand, it can be blocked by the enclosure assembly 30 to ensure privacy. On the other hand, the setting of the enclosure assembly 30 can effectively prevent items placed on the upper table top 20 from falling toward the front. Specifically, the upper table top 20 is fixedly connected to the inner wall surface of the enclosure assembly 30 facing the cabinet 10, and the upper table top 20 is located below the top surface of the enclosure assembly 30. In this way, part of the structure of the enclosure assembly 30 protrudes compared to the upper table top 20, thereby achieving a blocking effect.

[0056] Of course, the enclosure assembly 30 can also play a decorative role. Since the entire enclosure assembly 30 is a thin-walled structure, there are more material options to make the appearance of the enclosure assembly 30 more beautiful. Based on this aspect, when the cabinet 10 is set as a roughly rectangular parallelepiped, that is, the cabinet 10 includes a front surface and two side surfaces connected to the opposite sides of the front surface, the enclosure assembly 30 includes a front side portion 30a and edge portions 30b connected to the opposite sides of the front side portion 30a. The front side portion 30a is arranged in front of the front surface, and an edge portion 30b is correspondingly arranged in front of one side surface. The edge portion 30b can block part of the side surface. With this arrangement, the enclosure assembly 30 can block multiple areas of the main body 11, making the lifting platform 1 more beautiful.

[0057] In one embodiment, the enclosure assembly 30 includes an outer enclosure 31 and an inner enclosure 32. The outer enclosure 31 is arranged on the outside of the cabinet 10, and the inner enclosure 32 is connected to the inner wall surface of the outer enclosure 31 facing the cabinet 10 and is located above the upper table top 20. That is, the inner enclosure 32 covers the part of the inner wall surface of the outer enclosure 31 that is located above the upper table top 20.

[0058] Furthermore, the outer retainer 31 and the inner retainer 32 cooperate to form a limiting groove 33. The periphery of the upper table top 20 is embedded in the limiting groove 33 and is fixedly connected to at least one of the outer retainer 31 and the inner retainer 32. The inner retainer 32 can be fixedly connected to the inner wall surface of the outer retainer 31 by snapping, bonding, screw connection, etc. Specifically, the inner retainer 32 is connected to the upper part of the outer retainer 31, and the upper ends of the two can be flush. After the inner retainer 32 is connected, the inner retainer 32 protrudes from the rear surface of the outer retainer 31. In this way, the lower surface of the inner retainer 32 and the inner surface of the outer retainer 31 facing the rear side will define the limiting groove 33. Therefore, during the assembly process, the enclosure assembly 30 can be pre-mounted on the upper table board 20 for positioning through the cooperation between the limit groove 33 and the edge of the upper table board 20. Finally, the enclosure assembly 30 and the upper table board 20 and / or the lower table board 12 can be fixedly connected by screws, bonding, etc. It can be seen that such a design can improve the assembly convenience of the lifting platform 1.

[0059] Since the enclosure assembly 30 is arranged approximately in front of the cabinet 10, the storage space formed in the present application is open toward the rear side of the lifting platform 1. During actual use, the user stands on the rear side of the lifting platform 1, and can easily place items from the rear side of the lifting platform 1 into the storage space.

[0060] In actual use, for example, taking the scenario of using the lifting platform 1 in a classroom as an example, the storage space can be used to place books, handouts, etc. that need to be distributed. When there are a large number of these items, the upper table 20 and the enclosure assembly 30 can be raised together through the lifting mechanism 40 to increase the height of the storage space 1a. That is, by changing the lifting height of the upper table 20 and the lower table 12, the size of the storage space 1a can be adjusted. For example, according to the items that the user needs to place, the height spacing between the upper table 20 and the lower table 12 of the lifting platform 1 is adjusted until the required items can be placed in the storage space 1a. Furthermore, compared to existing lifting platforms, the lifting platform 1 of the present application achieves a change from a traditional single desktop for placing items to a double-layered storage space with two desktops. This allows items that originally had to be placed on the traditional desktop to be flexibly selected and adjusted in the lifting platform 1 of the present application, improving the use effect of the lifting platform. In addition, by changing the height spacing between the upper and lower desktops through the lifting mechanism 40, the size of the storage space 1a can be adjusted to meet different placement requirements.

[0061] In this way, the lifting platform 1 of the present application, on the basis of being able to realize the item placement function of an ordinary platform through the upper table board 20, can also improve the item placement capacity through the setting of the storage space 1a, and through the height adjustment method of the storage space 1a, it is convenient to adjust according to the actual situation of the items placed, so that the lifting platform 1 of the present application has a wider range of usage scenarios, and the convenience of use is greatly improved compared with traditional podiums.

[0062] Referring to FIG12 , to facilitate the placement of books, the lifting platform 1 of the present application can also be used in conjunction with a bookshelf 80, wherein the upper surface of the lower table top 12 is further provided with positioning holes, which are used to securely engage with the bookshelf placed on the lower table top 12. The positioning holes can be in the form of threaded holes or holes with smooth inner walls. In the case of threaded holes, the bookshelf 80 can be fastened to the positioning holes by, for example, screws. In the case of smooth inner walls, the bookshelf 80 can be inserted into the positioning holes by the support legs of the bookshelf, thereby achieving a stable fixation of the bookshelf.

[0063] It should be noted here that, in the present application, the lifting mechanism 40 supports the upper table top 20 above the lower table top 12. Then, when the lifting mechanism 40 is in the retracted extreme position, there is still a certain distance between the upper table top 20 and the lower table top 12, that is, the storage space also exists when the lifting mechanism 40 is in the retracted extreme position.

[0064] In order to improve the convenience of placing items in the storage space, please refer to Figure 4. The present application can further provide a rib 122 protruding upward on the periphery of the upper surface of the lower table board 12. The rib 122 can be set around the lower table board 12, or it can be a part of the lower table board 12. For example, the rib 122 can be a continuous form with openings formed at the head and tail ends, or the rib 122 can be a multi-segment form that is segmented and spaced apart, and an opening is formed between two adjacent segments. The present application does not impose any restrictions on this. By providing the rib 122, some cylindrical or spherical items stored in the placement space can be prevented from rolling out of the lower table board 12. It can be understood that in this embodiment, the rib 122 and the lower table board 12 can be in a split form. For example, the two can be manufactured separately and then fixedly connected by various means such as gluing, welding, and screw connection. Of course, the side 122 and the lower table top 12 may also be an integral structure. For example, both are made of plastic and are integrally produced through an injection molding process.

[0065] Also to improve the convenience of use, the lifting platform 1 of the present application can also include a cup holder 60, wherein the lower table top 12 is also provided with a mounting hole 123, and the cup holder 60 is mounted at the mounting hole 123. With this arrangement, the cup holder 60 will extend into the space inside the main body 11 without occupying too much storage space, thus improving the storage space's ability to place other items. In addition, the cup holder 60 is embedded in the main body 11. After the water cup is placed, the water cup can be partially embedded in the cup holder 60, and the exposed height is reduced. Therefore, even if the lifting platform 1 is in a state where the lifting mechanism 40 lowers the upper table top 20 to a relatively low height of the storage space, it is convenient to place the water cup in the cup holder 60 position, thereby improving the versatility of the lifting platform 1.

[0066] Please refer to Figure 3 again. In order to further ensure smoothness during the lifting of the upper table top 20, in one embodiment, the lifting platform 1 further includes a guide assembly 50. The guide assembly 50 is connected between the enclosure assembly 30 and the cabinet 10 and is used to support the enclosure assembly 30 during the lifting process. In this application, the guide assembly 50 can support the lower side of the enclosure assembly 30 away from the upper table top 20 and the main body 11, thereby preventing mutual interference and friction between the two during the lifting process.

[0067] To improve the stability of the enclosure assembly 30 during the lifting process, the enclosure assembly 30 of the present application is connected to the outer wall of the cabinet 10 via a guide assembly 50 on each of the two opposite sides in the left and right directions. It can be understood that when a guide assembly 50 is connected to each of the upper two sides in the left and right directions, the enclosure assembly 30 can be prevented from twisting during the lifting process, thereby achieving greater stability.

[0068] In one structural form, the guide assembly 50 includes a slider 52 and a slide rail 51 that slidably cooperate; the slider 52 is fixed to one of the inner wall surface of the enclosure assembly 30 and the outer wall surface of the cabinet 10, and the slide rail 51 is fixed to the other of the inner wall surface of the enclosure assembly 30 and the outer wall surface of the cabinet 10. Specifically, the slide rail 51 is fixed to the edge portion, and the slider 52 is fixed to the side surface of the cabinet 10. In this application, the slide rail 51 is arranged on the inner wall surface of the edge portion 30b of the enclosure assembly 30, and the slider 52 is arranged on the side surface of the main body 11. In this way, the slide rail 51 can also play a role in strengthening the structural strength of the enclosure assembly 30. In addition, the slide rail 51 itself is long, while the slider 52 is relatively short. When the slider 52 is fixed to the upper portion of the main body 11, when the enclosure assembly 30 rises, the slide rail 51 rises with it and does not become exposed. The slider 52 also remains hidden by the enclosure assembly 30. At this time, the entire guide assembly 50 is not exposed, which is beneficial to its structural protection. It is understood that the guide assembly 50 using the slider 52 and the slide rail 51 also has the characteristics of simple structure and low cost. In addition, the guide assembly 50 of the present application can also be a variety of other mechanisms that can achieve the guiding function, such as the combination of a roller and a slide rail, the combination of a polished rod and a guide sleeve, etc., and the present application does not limit this.

[0069] As for the lifting mechanism 40, firstly, since there is a gap between the enclosure assembly 30 and the cabinet 10, the lifting mechanism 40 can be installed on the outer surface of the cabinet 10 and located between the gap between the enclosure assembly 30 and the cabinet 10. In order to reduce the angle of the entire lifting platform 1, please refer to Figures 4 and 5. The present application can further provide an avoidance hole 121 on the lower table board 12, and the lifting mechanism 40 is passed through the avoidance hole 121. The output end 41 of the lifting mechanism 40 is installed and matched with the upper table board 12 through the avoidance hole 121. That is, the lifting mechanism 40 is partially located in the main body 11 and is installed and matched with the main body 11. In this way, the lifting mechanism 40 is set within the area of ​​the cabinet 10, and the design of the avoidance hole 121 will not cause the size of the entire lifting mechanism 40 to increase in either the front-to-back direction or the left-to-right direction. In this way, the space utilization rate is higher and the structural layout is more reasonable.

[0070] At the same time, the present application has at least two lifting mechanisms 40 spaced apart in the length direction of the lower table panel 12, which can improve the stability of driving the upper table panel 20 in the process of movement. In combination with the above content, the present application has guide components 50 set between each edge portion of the enclosure component 30 and the corresponding side surface of the main body 11, so the two lifting mechanisms 40 are arranged between the two guide components 50. In this way, during the force application process of the lifting mechanism 40, the enclosure component 30 and the upper table panel 20 are not prone to left and right shaking, and the structure is more stable.

[0071] As for the specific structural form of the lifting mechanism 40, the present application has various forms, among which the lifting mechanism 40 can adopt an electric push rod form, a cylinder form, a motor and a transmission assembly form, etc. In a specific implementation form, the lifting mechanism 40 includes a sleeve, a telescopic rod and a screw assembly. The sleeve is inserted into the avoidance hole 121 and is fixedly connected to the main body 11 of the cabinet 10. The telescopic rod is slidably nested in the sleeve. The telescopic rod has an output end. The screw assembly is connected to the telescopic rod for driving the telescopic rod to slide relative to the sleeve. It can be understood that the screw assembly includes a motor, a screw nut and a screw. The motor can be installed at the bottom of the sleeve and connected to the screw to drive the screw to rotate. The screw nut engages with the screw and is fixedly connected to the telescopic rod. When the motor drives the screw to rotate, the screw nut reciprocates in the length direction of the screw and drives the telescopic rod to slide relative to the sleeve to extend or retract, thereby achieving the lifting and lowering of the upper table 20. When the lifting mechanism 40 adopts the above-mentioned form, it has the characteristics of precise lifting process.

[0072] It can be understood that the above screw assembly is a structural form that adopts a motor and a transmission assembly. In other forms of transmission assemblies, it can also be a sprocket transmission structure, a pulley transmission structure, a gear rack matching structure, etc. This application does not limit this.

[0073] The lifting platform 1 of the present application can be adjusted in real time according to the needs of the user during use. Specifically, the lifting platform 1 also includes a controller 70, the lifting mechanism 40 is electrically connected to the controller 70, and the controller 70 is fixed to the upper table board 20. During use, the user can control the above at least two lifting mechanisms 40 to move simultaneously through the controller 70, so as to achieve the upper table board 20 to maintain a relatively horizontal posture for lifting and lowering. The present application fixes the controller 70 to the upper table board 20. The advantage is that in some scenarios, the user may also perform lifting operations on the upper table board 20 due to height factors. In this way, the controller 70 is linked with the upper table board 20, so that the controller 70 can always match the height of the user, which is convenient for user operation.

[0074] Furthermore, as mentioned above, some electronic devices such as microphones and displays are also placed on the upper table top 20. These electronic devices have conductive wires, and a conductive wire bundle is also provided between the controller 70 and the lifting mechanism 40. In order to properly arrange these conductive wires, please refer to Figure 6. The upper table top 20 includes an upper table top 21 and a bracket 22. The bracket 22 is fixed to the lower surface of the upper table top 21 and cooperates with the upper table top 21 to form a wiring groove 221. The output end 41 of the lifting mechanism 40 is connected to the bracket 22 and / or the upper table top 21. The wiring groove 221 is used to route the wires of the electronic devices, which makes the routing of the conductive wires more regular and safer.

[0075] In addition, to further strengthen the connection between the enclosure assembly 30 and the upper table top 20, as shown in Figures 7 and 8, the bracket 22 is further provided with a hanging hole 222. The enclosure assembly 30 is fixedly provided with a hook 34 on the inner wall of the outer block 31. The hook 34 engages with the hanging hole 222. The cooperation between the hanging hole 222 and the hook 34 makes the connection between the enclosure assembly 30 and the upper table top 20 more secure and less likely to become loose. Of course, the cooperation between the hook 34 and the hanging hole 222 can also achieve a pre-positioning effect during the assembly of the enclosure assembly 30.

[0076] Specifically, referring to Figures 9 to 11, the bracket 22 includes a frame portion 223 and a wiring portion 224. The frame portion 223 is fixed to the lower surface of the upper table top 21 and extends along the periphery of the upper table top 21. The above-mentioned hanging hole 222 is provided on the border of the frame portion 223. The above-mentioned controller 70 can also be connected to the frame portion 223 and located on the lower surface of the upper table top 21. This is beneficial to its structural protection. Through the provision of the frame portion 223, the frame portion 223 can effectively support the edge of the entire upper table top 21 and also achieve a structural strengthening effect on the upper table top 21.

[0077] The wiring portion 224 is mounted within the frame portion 223, and the ends of the wiring portion 224 are respectively connected to the corresponding frames of the frame portion 223. The output end 41 of the lifting mechanism 40 includes a top stop block, which is connected to both the frame portion 223 and the wiring portion 224. The wiring portion 224 includes two support bars 225 spaced apart from each other and a cover 226 detachably connected to the two support bars 225. The two support bars 225 are spaced apart in the front-to-back direction, and the ends of the support bars 225 are fixedly connected to the frame portion 223. The specific connection method can be welding, screw connection, etc. The cover 226 is connected to the middle of the two support bars 225. In this way, a socket 227 is defined between the two support bars 225, the cover 226, and the frame portion 223.

[0078] In one structural form, the support bar 225 can have a cross-sectional shape that is roughly "7"-shaped, that is, a flange is provided on the upper side of the support bar 225. In this way, after the output end 41 as a block structure can be inserted from the socket 227, the side of the output end 41 can be fixedly connected to the frame portion 223, and the output end 41 is stopped by the flanges on the two support bars 225. In this way, the output end 41 is fixedly connected to the frame portion 223 and the wiring portion 224. In this form, during the driving process, the entire upper table top 20 is subjected to more balanced force, and the connection structure is more stable. In other structural forms, the cross-section of the support bar 225 can also be square, and the side of the output end 41 can be fixedly connected to the wall of the socket 227 formed by the frame portion 223 and the support bar 225 through connectors such as screws. This form can also achieve the characteristic of a stable connection structure.

[0079] In this embodiment, the cover body 226 cooperates with the two support bars 225 to define the above-mentioned wiring groove 221, and the cover body 226 is designed to be detachably connected to the support bars 225. The specific detachable form can be a snap connection, a screw connection, etc., which facilitates the disassembly and maintenance operations of the wires in the later stage.
