Description

Technical Field

[0001] This application belongs to the field of LED display technology, and more specifically, relates to an edge-mounted external control box and an integrated LED display machine. Background Technology

[0002] Due to their large size, integrated LED display screens are typically shipped separately as display modules, control boxes, and support frames, requiring on-site assembly upon arrival. This process is cumbersome and inefficient. To address this issue, a model has been proposed that display modules be shipped separately; however, the control boxes on the integrated LED display screen have not been updated accordingly.

[0003] As a crucial functional component of LED displays, the control box's structure directly impacts the ease of transportation, installation efficiency, and convenience of subsequent use and maintenance. Traditional edge-mounted control boxes primarily house various control devices and connecting cables. During actual installation, operators must individually route the power cables for each module into the control box, then plug and match the connectors of adjacent modules. Simultaneously, signal cables must be cascaded to each display module, with some cables even needing to pass through the entire control box. This wiring method not only results in a chaotic and disorganized internal wiring configuration but also makes the installation process exceptionally cumbersome and time-consuming.

[0004] Furthermore, the installation structure of traditional control boxes has not fully considered compatibility requirements, making it difficult to achieve rapid and efficient on-site assembly under the new display module delivery model. Summary of the Invention

[0005] The purpose of this application is to provide an edge-mounted external control box and an integrated LED display screen to solve the problem that the edge-mounted external control box in the prior art is difficult to adapt to the efficient assembly after the display module is shipped.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0007] An externally mounted control box with an enclosed edge is provided for controlling an array display module, including:

[0008] A control box is located on the back of the display module. It includes column signal distribution terminals and column power distribution terminals. The column signal distribution terminals are used for signal connection with the display modules in the same column, and the column power distribution terminals are used for electrical connection with the display modules in the same column.

[0009] The mounting structure includes a fixing component and a sliding component. The fixing component is installed on the back of the display module and has a slot extending vertically. The sliding component is slidably inserted into the slot, and the control box is connected to the sliding component. The fixing component also has a movable pin, and the sliding component has at least two holes corresponding to the pin. The holes are spaced apart from each other vertically. When the pin is inserted into different holes, the control box has different mounting positions relative to the display module.

[0010] As a further improvement to the above technical solution:

[0011] Optionally, the control box has an opening on one side, and the column signal distribution terminal and column power distribution terminal are located on the main board of the control box near the opening.

[0012] When the pin is inserted into the uppermost socket on the slider, the opening of the control box is offset relative to the display module; when the pin is inserted into the lowermost socket on the slider, the opening of the control box is covered by the display module.

[0013] Optionally, the control box includes a hinge and a first box body and a second box body connected to two movable ends of the hinge, and at least one sliding member is installed on both the first box body and the second box body.

[0014] Optionally, the control box includes a high-voltage wiring area and a low-voltage wiring area, the projections of the high-voltage wiring area and the low-voltage wiring area on the circuit board plane of the control box being staggered from each other.

[0015] Optionally, the fastener has a bent portion that bends to one side, and the slot is formed on the inner side of the bent portion.

[0016] Optionally, at least two fixing members are installed on the display module, and the number and position of the sliding members installed on the external control box correspond to the fixing members.

[0017] Optionally, the insertion hole is a strip-shaped hole, and the extending direction of the strip-shaped hole intersects with the extending direction of the slot.

[0018] Optionally, the edge-mounted external control box also includes an edge-mounting structure, which is installed on the other side of the fixing member and located at the bottom of the display module; the edge-mounting structure includes a beam and a front panel, the beam is installed on the fixing member, the beam has an opening groove, the main body of the pin is located in the opening groove, and the front panel is detachably connected to the opening of the opening groove.

[0019] Optionally, the pin is an indexing pin, which includes a main bolt, a pin shaft, an elastic element, and a handle. The main bolt is connected to the fixing member, the pin shaft is slidably connected to the coaxial pin hole of the main bolt, one end of the pin shaft passes through the fixing member, one end of the pin shaft is connected to the handle, one end of the elastic element is connected to the main bolt, and one end of the elastic element is connected to the pin shaft.

[0020] When the handle is driven by an external force, the pin retracts into the pin hole; when the handle is removed by the external force, the pin extends out of the pin hole.

[0021] The beneficial effects of the edge-mounted external control box provided in this application are as follows:

[0022] The edge-mounted external control box provided in this application is suitable for a new transportation mode where display modules are shipped in arrays, enabling control of array-type display modules. Specifically, it includes a control box and a mounting structure. The control box is electrically connected to the display modules via signal lines. The control box includes column signal distribution terminals and column power distribution terminals. The column signal distribution terminals are used for signal connection with display modules in the same column, and the column power distribution terminals are used for electrical connection with display modules in the same column. The network cable and power cable connectors from each display module in the same column to the controller are centrally located within the control box below the corresponding column, ensuring uniform length of external network and power cables for each column. During on-site installation, the display modules in the array are assembled into a complete display, and the control box is mounted on the back of the display. Connection is completed by directly plugging the network and power cables into the corresponding terminals, avoiding the cumbersome wiring and fixing procedures of traditional methods, significantly improving installation efficiency and reducing wiring error rates. The mounting structure includes a fixing component and a sliding component. The fixing component is fixedly installed on the back of the display module and has a longitudinally extending slot on one side. The sliding component can slide along the slot for adjustment and is rigidly connected to the control box. The fixing component is equipped with a movable pin, and the sliding component has at least two corresponding insertion holes arranged along the extension direction of the slot. By selectively inserting the pin into different insertion holes, multiple height adjustments of the control box relative to the display module can be achieved. The entire installation process requires no additional tools and can be completed with simple insertion and pushing operations, significantly reducing installation difficulty and labor time.

[0023] This application also provides an integrated LED display screen, including display screen modules and the aforementioned edge-mounted external control box. The display screen modules are arranged in an array, and the edge-mounted external control box is mounted on the back of the display screen modules. The column signal distribution terminal of the edge-mounted external control box is connected to the display screen modules in the same column, and the column power distribution terminal of the edge-mounted external control box is electrically connected to the display screen modules in the same column.

[0059] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings.

[0060] like Figures 3 to 7 As shown, this application provides an edge-mounted external control box for controlling an array display module. Specifically, it includes a control box 3 and a mounting structure.

[0061] The control box 3 is electrically connected to the display module 4 via signal lines. Internally, it integrates core functional modules such as AC input connectors 36, relays 37, power supply 38, network port sub-board 39, transmitting card 310, OSD board 311, terminal block 312, and high-voltage switch 313. To further optimize the wiring structure, column signal distribution terminals 34 and column power distribution terminals 35 are added to the control box 3. Column signal distribution terminals 34 are used for signal connection with the display module 4 in the same column, and column power distribution terminals 35 are used for electrical connection with the display module 4 in the same column. The network cable and power cable connectors from the display module 4 in the same column to the controller are all centrally located within the control box below the corresponding column to ensure that the length of the external network cable and power cable remains uniform for each column. Figure 1 and Figure 2 As shown, during on-site installation, the rows of display modules 4 are assembled into a complete display screen, and the control box 3 is then mounted on the back of the complete display screen. The connection can be completed by directly plugging the network cable and power cable into the corresponding terminals. This avoids the cumbersome process of wiring and fixing in the traditional method, significantly improving installation efficiency and reducing the wiring error rate.

[0062] like Figure 9 and Figure 10 As shown, the mounting structure includes a fixing member 1 and a sliding member 2. The fixing member 1 is fixedly installed on the back of the display module 4, and has a longitudinally extending slot 11 on one side. The sliding member 2 can slide and adjust along the slot 11 and is rigidly connected to the control box 3. The fixing member 1 is equipped with a movable pin 12, and the sliding member 2 is provided with at least two insertion holes 21 arranged along the extension direction of the slot 11. By selectively inserting the pin 12 into the insertion holes 21 at different positions, the height of the control box 3 relative to the display module 4 can be adjusted to multiple levels.

[0063] During installation, the edge-mounted external control box of this application is first installed by mounting the fixing part 1 and the sliding part 2 on the corresponding display module 4 and control box 3, respectively. Then, two installers work together, each holding both ends of the control box 3. After straightening the drooping network cables and power cables, the control box 3 is pushed in the predetermined direction so that the pin 12 is accurately inserted into the first socket 21 to complete the initial mounting. Subsequently, the network cables, power cables, keypad, and standby button cables are connected in sequence. After all electrical connections are completed, the temporary fixing is released by pulling out the pin 12, and the control box 3 is pushed up until the pin 12 automatically engages in the second socket 21 to achieve final positioning. Finally, the safety fixing screws of each column are tightened to complete the entire installation. The entire installation process does not require any additional tools and can be completed with only simple insertion and pushing operations, significantly reducing the installation difficulty and labor time.

[0064] like Figure 1 and Figure 3As shown, in one specific embodiment of this application, the control box 3 has an opening on one side, and the signal connection terminals on the main board of the control box 3 are concentrated on the side near the opening. When the pin 12 is inserted into the uppermost socket 21 of the slider 2, the control box 3 is in the first working position. At this time, the opening and the display module 4 are misaligned, which facilitates cable connection and maintenance operations. When the pin 12 is inserted into the lowermost socket 21 of the slider 2, the control box 3 descends to the second working position. At this time, the back plate of the display module 4 just covers the opening of the control box 3, forming a complete protective structure. This ensures operability during installation and maintenance, and provides effective protection for the signal connection terminals in the working state, preventing external interference and physical damage. Switching between the two working positions can be achieved simply by switching the pin 12 between different sockets 21, making the operation simple and reliable.

[0065] like Figure 6 and Figure 8 As shown, in a specific embodiment of this application, the control box 3 adopts a segmented structure, including a hinge 31 and a first box body 32 and a second box body 33 connected to each other via the hinge 31. The two movable ends of the hinge 31 are fixedly connected to the first box body 32 and the second box body 33 respectively, allowing the two boxes to rotate relative to each other. At least one sliding member 2 is installed on each of the first box body 32 and the second box body 33 for engaging with the fixing member 1 on the display module 4. During transportation, the control box 3 can fold and retract the first box body 32 and the second box body 33 via the hinge 31, effectively reducing the overall packaging length, lowering packaging costs, and ensuring the structural strength of the control box 3 during transportation. In actual installation, simply unfolding the folded first box body 32 and the second box body 33 restores the working state.

[0066] In one specific embodiment of this application, the control box 3 adopts a partitioned layout, physically isolating the high-voltage wiring area from the low-voltage wiring area on the circuit board plane. These two areas are staggered on the circuit board projection surface of the control box 3, forming a clear electrical isolation zone. This layout optimizes component placement and wiring paths, maintaining sufficient electrical safety distance between the two areas, significantly reducing wire overlap and effectively minimizing electromagnetic interference (EMI) and signal crosstalk problems. This partitioned layout not only shortens the wiring length of various wires and simplifies wire types, but also reduces material costs and production assembly time, improving overall electromagnetic compatibility (EMC) performance.

[0067] like Figure 13 and Figure 14As shown in a specific embodiment of this application, the fixing member 1 is manufactured using an integral molding process. Its structure includes a bent portion extending to one side, which is formed into a "U"-shaped bent structure by stamping. The inner side of the bent portion naturally forms a slot 11 for accommodating the sliding member 2. This integral structural design not only ensures the structural strength of the slot 11 but also avoids the stress concentration problems that may occur with traditional welding or assembly methods. The geometry of the bent portion can both meet the smooth sliding requirements of the sliding member 2 and provide a reliable positioning reference for the pin 12, ensuring the positional accuracy of the control box 3 during the mounting process.

[0068] In one specific embodiment of this application, a first fixing member and a second fixing member are provided on the mounting base, and the two are arranged symmetrically. The opening direction of the bent portion of the first fixing member is 180 degrees opposite to the opening direction of the bent portion of the second fixing member. This symmetrical layout design allows the two fixing members to form a mutually cooperating installation reference. Through this reverse-arranged bent portion structure, the first and second fixing members can refer to each other during installation, ensuring the installation accuracy of the control box 3. This arrangement not only improves the accuracy of installation positioning but also enhances the stability of the overall structure, enabling the control box 3 to maintain a uniform stress state after mounting, achieving a more stable support effect.

[0069] like Figure 3 As shown, in one specific embodiment of this application, at least two fixing members 1 are provided on the back of the display module 4. These fixing members 1 are evenly distributed at preset intervals on the load-bearing positions of the module frame. The control box 3 is equipped with the same number of sliding members 2, the position of each sliding member 2 matching the installation position of the fixing members 1. By setting multiple fixing members 1 and sliding members 2, the weight of the control box 3 can be evenly distributed to multiple stress points of the display module 4, effectively avoiding the problem of local stress concentration. Through multi-point support, not only is the stability of the overall structure improved, but the load strength requirements of individual connection parts are also significantly reduced, thereby extending the service life of the equipment.

[0070] like Figure 11 and Figure 12As shown in a specific embodiment of this application, the insertion hole 21 provided on the slider 2 adopts a strip-shaped hole structure. The long axis of the strip-shaped hole forms a certain angle with the extension direction of the slot 11, so that the pin 12 has a greater positional tolerance during insertion, which can effectively compensate for positioning errors caused by installation deviations or manufacturing tolerances. The geometric features of the strip-shaped hole allow the pin 12 to have a certain displacement margin in the long axis direction of the hole, ensuring that even in the presence of assembly errors, the pin 12 can still be smoothly inserted into the insertion hole 21 to complete positioning. This not only improves the reliability of the assembly process, but also reduces the alignment accuracy requirements during installation, while maintaining the precise positioning function of the pin 12 in the extension direction of the slot 11. The cooperation between the strip-shaped hole and the pin 12 ensures both ease of installation and does not affect the stability of the final positioning.

[0071] like Figure 13 and Figure 14 As shown, in a specific embodiment of this application, the pin 12 is specifically an indexing pin, which includes a main bolt 121, a pin 122, an elastic element, and a handle 123. The main bolt 121 is fixedly mounted on the fixing member 1, and has a coaxial pin hole inside. The pin 122 is axially slidably disposed in the pin hole of the main bolt 121, with one end of the pin 122 passing through the fixing member 1 and the other end connected to the handle 123. One end of the elastic element is connected to the main bolt 121, and the other end is connected to the pin 122. When an external force is applied to the handle 123, the pin 122 retracts axially along the pin hole; when the external force is released, the restoring force of the elastic element causes the pin 122 to automatically extend out of the pin hole. The preload of the elastic element maintains the stable extended state of the pin 122, ensuring reliable engagement with the insertion hole 21, while allowing for quick unlocking via the handle 123.

[0072] like Figure 4 and Figure 5 As shown, in a specific embodiment of this application, the edge-mounted external control box also includes an edge-mounting structure 5, which is installed on the other side of the fixing member 1 and located at the bottom of the display module 4. The edge-mounting structure 5 includes a beam 51 and a front panel 52, wherein the beam 51 is fixedly connected to the fixing member 1, and its interior has an opening groove for accommodating the main body of the pin 12. The front panel 52 is detachably installed at the opening position of the opening groove, forming a complete edge-mounted appearance. The front width of the edge-mounting structure 5 is controlled within 30mm, which meets the internal wiring requirements and ensures the structural installation strength. When the edge width of the other three sides of the display is 4mm, the screen-to-body ratio of the 136-inch display can reach more than 98%. The overall depth of the control box 3 is approximately 30mm, which minimizes the impact on the overall appearance of the display while ensuring functionality.

[0073] like Figure 1 and Figure 2As shown, this application also provides an integrated LED display screen, including the edge-mounted external control box and the display module 4 as described in the above embodiments. The display modules 4 are shipped in a row, and then each row of display modules 4 is installed in an array at the user site. The edge-mounted external control box is mounted on the back of the display module 4. The column signal distribution terminal 34 of the edge-mounted external control box is connected to the display module 4 in the same row, and the column power distribution terminal 35 of the edge-mounted external control box is electrically connected to the display module 4 in the same row. The network cable and power cable connectors from the display module 4 in the same row to the controller are all centrally located in the control box below the corresponding column, ensuring that the length of the external network cable and power cable for each row remains uniform. During on-site installation, only direct plug-in is required to complete the connection, avoiding the cumbersome wiring and fixing procedures of traditional control boxes, improving installation efficiency and reducing wiring error rates. This edge-mounted external control box is suitable for connecting and controlling array display modules, and can also achieve fast and efficient on-site assembly even in the case of display modules being shipped out in batches.

[0074] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
