[0022] This application proposes an outdoor liftable and foldable all-in-one machine, which aims to provide a smart display terminal that does not require external equipment, is waterproof and dustproof, and can be lifted and folded for outdoor advertising, temporary events, bus stop guidance, scenic spot tours and other scenarios, so as to meet the comprehensive needs of outdoor dynamic information display for convenience, environmental adaptability and spatial flexibility.

[0023] like Figures 1 to 10 As shown, the embodiment of the outdoor height-adjustable and foldable all-in-one machine 100 proposed in this application includes a base 10, a column assembly 20, a control assembly 50, a sealing assembly 60, and a display assembly 40. The base 10 has casters 11 at its bottom. The column assembly 20 is fixedly connected to the top surface of the base 10, and a receiving groove (not shown) is provided on the back side of the column assembly 20 (the column assembly 20 is located behind the display assembly 40; the side facing the display assembly 40 is the front, and the side facing away from the display assembly 40 is the back). The control assembly 50 includes a control box 51, a control main board 52, and a control panel 53. The control box 51 is located in the receiving groove, the control main board 52 is located inside the control box 51, and the control panel 53 is located on the outer surface of the control box 51 and electrically connected to the control main board 52. The sealing assembly 60 is connected to the control box 51 and fills the gaps and / or holes in the control box 51. The display component 40 is vertically and retractably connected to the column component 20. The display component 40 includes several screens, which are rotatably connected to each other so that the screens can be in a folded state and an unfolded state.

[0024] The base 10 is located at the very bottom of the entire device, supporting the entire weight of the column assembly 20, bracket assembly 30, and display assembly 40, providing stable support for the whole unit. The base 10 is equipped with casters 11, typically with brakes, allowing users to easily move the entire device to different positions as needed and lock them in place to prevent slippage. The column assembly 20 is fixedly connected to the top surface of the base 10 and extends vertically upwards. Its back has a receiving groove to accommodate the control assembly 50, thus concealing the control assembly 50 inside the column assembly 20. This prevents the control assembly 50 from being exposed and affecting the overall aesthetics of the device, while also providing some protection.

[0025] Reference Figure 10The control component 50 includes a control box 51, a control motherboard 52, and a control panel 53. The control box 51, serving as the housing of the control component 50, is located within a receiving slot, providing a mounting base for the control motherboard 52 and offering physical protection for the internal electronic components. The control motherboard 52, located inside the control box 51, is the core of the entire device's control system, processing image signals, executing operating system commands, and responding to operation signals from the control panel 53. The control panel 53 is located on the outer surface of the control box 51 and is electrically connected to the control motherboard 52. Users can use the control panel 53 to perform operations such as powering on / off, adjusting brightness, controlling volume, and switching signal sources. By integrating the control motherboard 52 and control panel 53 within the control box 51 and installing the entire control box 51 within the receiving slot of the column assembly 20, this outdoor height-adjustable and foldable all-in-one machine 100 achieves built-in integration of the control system, enabling intelligent operation immediately upon power-on without the need for external computers or players.

[0026] The sealing assembly 60 is connected to the control box 51 and fills the gaps and / or holes in the control box 51. Specifically, during the manufacturing process, the control box 51 inevitably has potential water ingress paths such as gaps in the housing assembly, screw mounting holes, and wire harness passage holes. The sealing assembly 60 includes sealing materials such as waterproof adhesive 61, sealing rings, and waterproof connectors. These sealing materials are applied to or installed at the gaps and / or holes in the control box 51, effectively preventing rainwater, moisture, and dust from the external environment from entering the interior of the control box 51.

[0027] The display component 40 is vertically and flexibly connected to the column component 20. The display component 40 includes several screens, which are rotatably connected to each other, allowing the screens to be folded and stacked together to form an unfolded display image. The lifting function allows the display component 40 to be adjusted to a suitable height according to the viewing scenario: for example, lowering it to its lowest position for seated viewing or low-position installation; or raising it to its highest position for standing viewing or higher viewing angles. The folding function allows the screens to be stacked for storage or transportation, significantly reducing the overall width of the display component 40, lowering the center of gravity and height, and reducing the space required for storage and transportation. When needed for display, the screens can be unfolded and combined to form a large-format display image, meeting the requirements for large-size displays.

[0028] In summary, this outdoor height-adjustable and foldable all-in-one machine 100 integrates the control component 50 into the column component 20, enabling the entire machine to operate independently without the need for an external computer or player. This achieves intelligent operation that is ready to use immediately, overcoming the cumbersome deployment issues caused by the requirement for external playback devices in ordinary displays. Simultaneously, by incorporating the sealing component 60 to fill gaps and / or holes in the control box 51, the control box 51 possesses excellent waterproof and dustproof performance, resisting rain, moisture, and dust intrusion in the outdoor environment, thus ensuring long-term stable operation of the entire machine in outdoor environments. Furthermore, by setting the display component 40 to a height-adjustable structure, the display height can be flexibly adjusted according to the usage scenario to adapt to different viewing needs. Additionally, by setting the display component 40 to a multi-screen rotating connection structure, it can form a large display screen in the unfolded state to meet the display area requirements for outdoor dynamic information display, and can reduce its size in the folded state for easy transportation and storage.

[0029] Reference Figure 1 In some embodiments of the outdoor height-adjustable and foldable all-in-one machine 100, a bracket assembly 30 is also included, which is height-adjustably connected to the column assembly 20. The display assembly 40 includes a first screen 41, a second screen 42, and a third screen 43. The back of the first screen 41 is fixedly connected to the bracket assembly 30. The first screen 41 has a first side and a second side along the width direction. The second screen 42 and the third screen 43 are rotatably connected to the first side and the second side, respectively. The second screen 42 and the third screen 43 have a folded state that is folded against the first screen 41, and an unfolded state that is relative to the first screen 41.

[0030] In practical applications, the bracket assembly 30 can slide and engage with the column assembly 20 via a slider or linear bearing, and move up and down along the column assembly 20 under the action of a motor, cylinder, or manual crank. The bracket assembly 30 is used to fix and install the display assembly 40, and drives the display assembly 40 to rise and fall together. In this embodiment, the display assembly 40 has three screens, namely a first screen 41, a second screen 42, and a third screen 43. The first screen 41 serves as the main screen, and its back is fixedly connected to the bracket assembly 30 by bolts or a hanging structure. The first screen 41 has a first side and a second side along the width direction, namely the left side and the right side. The second screen 42 and the third screen 43 serve as secondary screens, and are rotatably connected to the first side and the second side of the first screen 41 by hinges or latches, respectively.

[0031] Figure 2 This is a schematic diagram showing component 40 raised to its highest position and in a folded state. Figure 3 This is a schematic diagram showing component 40 raised to its highest position and in its unfolded state. Figure 4This diagram illustrates the display component 40 at its lowest point and in a folded state. When needed for display, the second screen 42 and the third screen 43 can be unfolded relative to the first screen 41 to form a large-format display screen, meeting the requirements for large-size displays. The display component 40 can be adjusted to a suitable height depending on the viewing scenario: for example, lowering it to its lowest position is suitable for seated viewing or low-position installation; or raising it to its highest position is suitable for standing viewing or higher viewing angles. When storing or transporting, the second screen 42 and the third screen 43 can be rotated inwards, folding them against the first screen 41, significantly reducing the overall width of the display component 40. Simultaneously, lowering the display component 40 to its lowest position lowers the overall center of gravity and height, further reducing the space required for storage and transport. Furthermore, the base 10 is equipped with casters 11 at its bottom for easy movement, improving the device's portability.

[0032] In summary, this outdoor height-adjustable and foldable all-in-one machine 100, through the coordinated layout of the base 10, column assembly 20, control assembly 50, sealing assembly 60, and display assembly 40, organically integrates a foldable three-screen structure, a height-adjustable support assembly 30, and a movable base 10 structure into one unit. This allows for flexible switching between large-format display in exhibition mode and compact storage and transportation mode, while also catering to the height adjustment needs of different viewing scenarios. Furthermore, the sealing assembly 60 provides a waterproof seal for the control box 51, enabling it to adapt to complex outdoor environments. The second screen 42 and the first screen 41, as well as the third screen 43 and the first screen 41, are rotatably connected via concealed hinges. Each concealed hinge includes a first hinge piece, a second hinge piece, and a pivot connecting them. The inner sides of the first and second side frames of the first screen 41 have first mounting grooves matching the shape of the first hinge piece. The first hinge piece is embedded in these first mounting grooves and fixedly connected to the frame of the first screen 41 by screws or rivets. After installation, the surface of the first hinge piece is no higher than the outer surface of the side of the first screen 41. Similarly, the inner sides of the corresponding sides of the second screen 42 and the third screen 43 have second mounting grooves matching the shape of the second hinge piece. The second hinge piece is embedded in these second mounting grooves and fixedly connected to the screen frame by screws or rivets. After installation, the surface of the second hinge piece is no higher than the outer surface of the side of the screen. The pivot passes through the bushings of the first and second hinge pieces, achieving hinged connection between them.

[0033] When the second screen 42 or the third screen 43 rotates relative to the first screen 41, the first hinge piece and the second hinge piece rotate relative to each other around the pivot. Since the first and second hinge pieces are respectively embedded inside the side of their respective screens, and the surface of the hinge pieces does not extend beyond the outer surface of the side of the screen, the side of the screen remains flat at the hinge installation position, with no exposed hinge structure. The hinges are completely built into the side of the screen, not occupying the splicing gap between screens, allowing the second screen 42, the third screen 43, and the first screen 41 to fit tightly together in the unfolded state, with minimal gaps between adjacent screens.

[0034] In one embodiment of this application, the column assembly 20 further includes a lifting drive component, which comprises a first column 21 and a second column 22, respectively disposed on both sides of the control box 51. The first column 21 and the second column 22 are slidably connected to a first slider 211 and a second slider 221, respectively. The first slider 211 is connected to a first drive component 26, and the second slider 221 is connected to a second drive component 27. The bracket assembly 30 is fixedly connected to the first slider 211 and the second slider 221, thereby rising and falling synchronously with the first slider 211 and the second slider 221.

[0035] The first drive component 26 and the second drive component 27 can be waterproof electric actuators, lead screw motors, or synchronous belt modules, effectively preventing moisture from corroding them. Furthermore, each of the first drive component 26 and the second drive component 27 can be fitted with a waterproof cover (not shown). This waterproof cover is stamped from stainless steel or rust-proof cold-rolled steel, and its shape matches the outline of the drive component. The waterproof cover, fitted over the first drive component 26 and the second drive component 27, isolates them from rainwater, further improving their waterproof performance.

[0036] In order to connect the screen assembly and the bracket assembly 30, in one embodiment of this application, the back of the first screen 41 is provided with a plurality of first hooks, and the bracket assembly 30 is provided with hook holes for the first hooks to be inserted. After the first hooks are inserted into the hook holes, they move downwards to engage and fix with the bracket assembly 30.

[0037] Specifically, the first pin includes a horizontally extending neck and a head connected to the end of the neck, the diameter of which is smaller than the diameter of the head. The pin hole includes an intersecting insertion section and a locking section. The diameter of the insertion section matches the head of the first pin to allow the head to pass through, and the width of the locking section matches the diameter of the neck but is smaller than the diameter of the head. During installation, the head of the first pin is aligned with the insertion section and inserted, allowing the head to completely pass through the pin hole. Then, the first screen body 41 is moved downwards, causing the neck to slide into the locking section. At this point, the head is locked by the wall of the pin hole edge and cannot be dislodged, thus achieving the locking and fixing of the first pin to the bracket assembly 30. During disassembly, the first screen body 41 is lifted upwards, moving the neck from the locking section to the insertion section, and then the head of the first pin is pulled out from the insertion section. With this hook-and-loop connection, the display component 40 can be quickly installed onto or removed from the bracket component 30 without tools, facilitating maintenance and replacement. Furthermore, no screws or connectors are visible from the front, and all fixing structures are hidden on the back of the screen, ensuring the integrity and aesthetics of the front of the display component 40 and enhancing the overall integrated visual effect of the device.

[0038] Reference Figure 1 The support assembly 30 may include a plurality of first support plates 31 and second support plates 32. The plurality of first support plates 31 extend along the width direction of the first screen body 41 and are arranged vertically at intervals. The plurality of second support plates 32 extend along the height direction of the first screen body 41. The second support plates 32 are connected between adjacent first support plates 31, forming a grid-like frame structure together with the first support plates 31. Pin holes are provided in each first support plate 31 and / or second support plate 32. After the first hook on the back of the first screen body 41 is inserted into the pin hole, it can be moved downward to engage and fix with the first support plate 31 and / or second support plate 32. The support assembly 30 is designed as a grid-like support structure, which can effectively reduce its own weight while ensuring load-bearing strength.

[0039] In some embodiments, the column assembly 20 also has a cavity located above the receiving groove. The cover plate of the cavity has a cable feeding channel 23. The lifting drive component also includes a first guide rail and a first cable chain 25. The first guide rail is connected to the cover plate and extends along the length of the cable feeding channel 23. The first cable chain 25 is movably wrapped around the first guide rail and has a pulling part, which is fixedly connected to the first screen body 41. The control assembly 50 also includes a wire harness assembly. One end of the wire harness assembly is electrically connected to the control motherboard 52, and the other end of the wire harness assembly passes through the first cable chain 25 and is electrically connected to the display assembly 40. When the bracket assembly 30 drives the first screen body 41 to rise and fall, the first screen body 41 pulls the pulling part of the first cable chain 25 to move synchronously. The main body of the first cable chain 25 rolls or slides along the first guide rail, thereby providing traction and constraint for the wire harness passing through the first cable chain 25, preventing the wire harness from being excessively stretched, bent, or rubbing against and interfering with surrounding components during the lifting process.

[0040] In this technical solution, the wiring harness assembly includes a first wiring harness for electrical connection with the first screen body 41, a second wiring harness for electrical connection with the second screen body 42, and a third wiring harness for electrical connection with the third screen body 43.

[0041] The display component 40 also includes a hollow first wire-concealing beam 44, a second wire-concealing beam 45, and a third wire-concealing beam 46. The first wire-concealing beam 44 is connected to the bottom of the first screen body 41 and extends along the width direction of the first screen body 41. The second wire-concealing beam 45 is connected to the bottom of the second screen body 42 and extends along the width direction of the second screen body 42. The third wire-concealing beam 46 is connected to the bottom of the third screen body 43 and extends along the width direction of the third screen body 43. The second wire-concealing beam 45 and the third wire-concealing beam 46 are rotatably connected to the first wire-concealing beam 44. When the second screen body 42 and the third screen body 43 are folded or unfolded, the second wire-concealing beam 45 and the third wire-concealing beam 46 rotate relative to the first wire-concealing beam 44. Each wire-concealing beam can be a hollow, elongated shell structure with a rectangular, circular, or other shaped cross-section. Each wire-concealing beam can be fixedly connected to the bottom of the corresponding screen body by screws or clips.

[0042] The bottom of the first screen body 41 is provided with a first terminal block 411, the bottom of the second screen body 42 is provided with a second terminal block 421, and the bottom of the third screen body 43 is provided with a third terminal block 431. The end of the first wire harness away from the control box 51 is built into the first cable concealing beam 44 and electrically connected to the first terminal block 411. The end of the second wire harness away from the control box 51 is built into the second cable concealing beam 45 and electrically connected to the second terminal block 421. The end of the third wire harness away from the control box 51 is built into the third cable concealing beam 46 and electrically connected to the third terminal block 431. In this embodiment, by placing the terminal blocks at the bottom of the screen body and using the cable concealing beam to hide the wire harness, there are no exposed wires on the front and back of the screen body, resulting in a clean appearance.

[0043] Furthermore, a lead wire box 412 is provided on the back of the first screen body 41, and the side wall of the lead wire box 412 is provided with an inlet and an outlet. The inlet faces the direction of the control box 51, and the outlet faces the direction of the first cable-concealing beam 44. The top of the first cable-concealing beam 44 is provided with a first cable entry port. After the cable harness assembly is led out from the control box 51, it passes through the inlet, the outlet, and the first cable entry port in sequence before entering the first cable-concealing beam 44.

[0044] The first wire-concealing beam 44 has a first wire-concealing channel inside, the second wire-concealing beam 45 has a second wire-concealing channel inside, and the third wire-concealing beam 46 has a third wire-concealing channel inside. The second and third wire-concealing channels are respectively connected to the first wire-concealing channel. The lead box 412 is used to centrally guide and constrain the wire harness, preventing it from becoming tangled. After the second wire harness is led out from the control box 51, it flows sequentially through the first and second wire-concealing channels and then is electrically connected to the second terminal 421. After the third wire harness is led out from the control box 51, it flows sequentially through the first and third wire-concealing channels and then is electrically connected to the third terminal 431. This embodiment's technical solution, through interconnected wire-concealing channels, achieves orderly distribution and guidance of the three wire harnesses within the wire-concealing beams, resulting in a clear and reasonable layout.

[0045] Furthermore, the first cable-concealing channel is equipped with a second guide rail 47 and a second cable chain 48. The second guide rail 47 extends along the length of the first cable-concealing channel, and the second cable chain 48 is movably wrapped around the second guide rail 47. The second cable harness is inserted into the second channel after passing through the second cable chain 48, and the third cable harness is inserted into the third channel after passing through the second cable chain 48. When the second screen 42 and the third screen 43 are folded or unfolded relative to the first screen 41, the second cable-concealing beam 45 and the third cable-concealing beam 46 will rotate relative to the first cable-concealing beam 44. The second and third cable harnesses, which are threaded within the second cable chain 48, will move along the second guide rail 47 with the second cable chain 48. The function of the second cable chain 48 is to pull and protect the second and third cable harnesses, preventing them from being squeezed, stretched, or worn during rotation, and ensuring the long-term reliability of the electrical connection.

[0046] Reference Figure 7 or Figure 8 The column assembly 20 also includes a water baffle 28, which is disposed on the top of the first column 21 and the second column 22 and covers the cavity 22.

[0047] Specifically, the baffle 28 is fixedly connected to the top of the first column 21, the second column 22, and the cover plate 23 by screws or other means. The shape of the baffle 28 matches the opening shape of the cavity 22, and its coverage area is equal to or greater than the opening area of ​​the cavity 22, ensuring that the baffle 28 can completely cover the upper opening of the cavity 22. The baffle 28, covering the cavity 22, effectively blocks rainwater or condensation dripping from above, preventing moisture from entering the cavity 22. Furthermore, the connection between the baffle 28 and the first column 21 and the second column 22 can be equipped with sealing gaskets or coated with waterproof sealant to eliminate the risk of water seepage at the connection gaps. The baffle 28 can be made of stainless steel, aluminum alloy, or rust-proof cold-rolled steel to ensure its corrosion resistance in long-term outdoor use.

[0048] In one embodiment of this application, the control box 51 includes a box body 511, a first door cover 512 and a second door cover 513. The box body 511 is provided with a first receiving groove and a second receiving groove arranged vertically at intervals. The control main board 52 is disposed in the first receiving groove. The second receiving groove is provided with a wiring plug 54 electrically connected to the control main board 52. The first door cover 512 is rotatably connected to the box body 511 and is used to seal the opening of the first receiving groove. The second door cover 513 is rotatably connected to the box body 511 and is used to seal the opening of the second receiving groove.

[0049] The sealing assembly 60 includes a waterproof adhesive 61 and a waterproof ring 62. The waterproof adhesive 61 covers the control panel 53 to prevent moisture from seeping in through the gap between the control panel 53 and the housing 511. The waterproof ring 62 is connected to the side of the first cover 512 facing the first receiving groove, and the waterproof ring 62 is arranged around the periphery of the first cover 512. When the first cover 512 is closed, the waterproof ring 62 presses tightly against the groove wall of the first receiving groove, thereby forming a reliable seal and effectively preventing rainwater, moisture, and dust from entering the interior of the control box 51. In specific applications, the waterproof ring 62 can be a rubber ring or EVA foam.

[0050] It should be noted that, in addition to the aforementioned waterproofing measures, this application can also apply or fill waterproof adhesive, sealant, or sealing wax to any joints, connection interfaces, wire passage holes, and structural mating surfaces in the entire machine that may pose a risk of water leakage, as needed, to form a comprehensive waterproof sealing barrier. For example, waterproof connectors can be provided at the wire inlet and outlet of the lead box 412. The rubber parts inside the connector are compressed and wrapped around the outer sheath of the wire harness, thereby achieving a seal at the point where the wire harness enters.

[0051] Reference Figure 5 and Figure 6 In a specific application, the display component 40 may further include a first limiting block 422 and a second limiting block 432. The first limiting block 422 has a first fixing part and a first rotating part. The first fixing part is fixedly connected to the top of the second screen body 42, and the first rotating part is rotatably connected to the first fixing part. The second limiting block 432 has a second fixing part and a second rotating part. The second fixing part is fixedly connected to the top of the third screen body 43, and the second rotating part is rotatably connected to the second fixing part.

[0052] The first fixing part has a first limiting post protruding from it, and the first screen body 41 has a first limiting hole for the first limiting post to be inserted into. In the folded state, the first rotating part rotates to fit against the top surface of the first screen body 41, and the first limiting post is inserted into the first limiting hole, thereby locking the second screen body 42. When the second screen body 42 is rotated inward to the folded state, the user can rotate the first rotating part to fit against the top surface of the first screen body 41, at which point the first limiting post is inserted into the first limiting hole. The relative position of the second screen body 42 and the first screen body 41 is locked through the post-hole cooperation, preventing the second screen body 42 from accidentally unfolding outward during transportation or storage.

[0053] Similarly, the second fixing part is provided with a second limiting post, and the first screen body 41 is provided with a second limiting hole for the second limiting post to be inserted. In the folded state, the second rotating part rotates to fit against the top surface of the first screen body 41, and the second limiting post is inserted into the second limiting hole, thereby realizing the locking of the third screen body 43.

[0054] In some embodiments, the first limiting block 422 and the second limiting block 432 are made of ferromagnetic material (such as iron, cobalt, or nickel). A magnet is provided on the top of the first screen body 41, which can be attached or embedded in the top of the first screen body 41. In the folded state, the first rotating part and the second rotating part rotate to the top surface of the first screen body 41 and are magnetically attracted and fixed with the magnet. When the second screen body 42 and the third screen body 43 are rotated to the folded state, the user rotates the first rotating part and the second rotating part to the top surface of the first screen body 41, and the magnet firmly attracts and fixes the first rotating part and the second rotating part through magnetic attraction, thereby locking the screen body. The magnetic locking method does not require precise alignment of the holes, making operation faster. In specific applications, the above-mentioned mechanical post-hole insertion locking and magnetic locking methods can be combined, that is, limiting posts / holes and magnets are set simultaneously to improve locking reliability and operational convenience.

[0055] Reference Figure 11 and Figure 12 This application also proposes an outdoor LED display unit 1000, which includes an outdoor liftable and foldable integrated unit 100 and a storage box 800. For the specific structure and internal connection relationship of the outdoor liftable and foldable integrated unit 100, please refer to the foregoing embodiments. Since the outdoor LED display unit 1000 adopts the technical solutions of all the above embodiments, it has at least the beneficial effects of all the above embodiments, and will not be repeated here.

[0056] The storage box 800 includes a base plate 81, a first cover 82 and a second cover 83. The first cover 82 and the second cover 83 are assembled together and detachably connected. The first cover 82 and the second cover 83 are detachably connected to the top of the base plate 81. The first cover 82, the second cover 83 and the base plate 81 form a storage cavity. The outdoor liftable and foldable all-in-one machine 100 is housed in the storage cavity, and the base 10 is detachably fixed to the base plate 81.

[0057] The first cover 82 and the second cover 83 are detachably connected by fasteners, snaps, or screws. When the first cover 82, the second cover 83, and the base plate 81 are connected and fixed, they together form a closed storage cavity. The outdoor height-adjustable folding all-in-one device 100 is placed inside this storage cavity when folded and the display component 40 is at its lowest position. When the outdoor height-adjustable folding all-in-one device 100 needs to be used, the first cover 82 and the second cover 83 can be removed from the base plate 81, and then the base 10 of the outdoor height-adjustable folding all-in-one device 100 can be separated from the base plate 81 of the storage box 800 to remove the outdoor height-adjustable folding all-in-one device 100 from the storage box 800. The storage box 800 provides a safe storage and transportation environment for the outdoor height-adjustable folding all-in-one device 100, effectively preventing it from being affected by collisions, dust, or moisture during idle periods or transportation.

[0058] exist Figure 13 and Figure 14 In the embodiment shown, the base 10 is provided with a guide rail 12 on its side, and the bottom of the base plate 81 is provided with a slide rail 811 that cooperates with the guide rail 12. The base plate 81 is provided with a clearance opening 810 for the base 10 to pass through. The base 10 partially passes through the clearance opening 810, so that the guide rail 12 slides into the slide rail 811, thereby realizing the sliding connection between the base 10 and the base plate 81.

[0059] Specifically, the cross-section of the guide rail 12 can be T-shaped, L-shaped, or dovetail-shaped. The bottom of the base plate 81 is provided with a slide rail 811 that matches the guide rail 12. The slide rail 811 is a groove extending in the same horizontal direction, and its cross-sectional shape is complementary to that of the guide rail 12. The base plate 81 also has a clearance opening 810 for the base 10 to pass through. The clearance opening 810 provides a channel for the base 10 to pass from below the base plate 81 to above the base plate 81, so that the base 10 can pass through the base plate 81, thereby aligning the guide rail 12 on its side with the slide rail 811 on the bottom of the base plate 81 and achieving a sliding connection. During installation, first lift the base plate 81 and place it above the base 10, aligning the base 10 with the clearance opening 810 of the base plate 81. Then, move the base plate 81 downwards or lift the base 10 upwards, allowing the base 10 to pass through the clearance opening 810. At this point, the guide rail 12 on the side of the base 10 and the slide rail 811 at the bottom of the base plate 81 are at the same height and their ends are opposite. Next, push the base plate 81 or the base 10 horizontally, causing the guide rail 12 to gradually slide into the slide rail 811 until the base 10 and the base plate 81 move to the predetermined relative position. During disassembly, pull the base plate 81 horizontally in the opposite direction to disengage the guide rail 12 from the slide rail 811. Then, lift the base plate 81 upwards or move the base 10 downwards, allowing the base 10 to exit from the clearance opening 810, thus completing the separation of the base plate 81 and the base 10.

[0060] Furthermore, the storage box 800 also includes a sealing component 84, which is detachably connected to the bottom plate 81 (such as by screws or clips) to seal the clearance opening 810 and prevent dust or foreign objects from entering.

[0061] Furthermore, the bottom of the base plate 81 is also equipped with casters 11. When it is necessary to take the outdoor liftable and foldable all-in-one machine 100 out of the storage box 800 and deploy it to the site of use, the storage box 800 can be moved to a suitable position by the casters 11, which improves the convenience of the storage box 800 in the transportation scenario.
