[0002] With the rapid development of the LED industry, LED display products are becoming increasingly popular in our lives, especially on stage.

[0003] Currently, the installation and disassembly of LED cabinet control boxes usually require the cooperation of both hands. This method has many shortcomings in practical applications: the control box requires the cooperation of both hands for initial positioning during installation, which is cumbersome, inefficient, and difficult to meet the needs of rapid assembly and maintenance. Summary of the Invention

[0004] The purpose of this application is to provide a central control box module and an LED display cabinet, which solves the problem of cumbersome operation and low efficiency caused by the need for two hands to work together for initial positioning during the installation of traditional control boxes.

[0005] To achieve the above objectives, this application provides a central control box module, comprising:

[0006] The middle frame assembly includes a rotary support structure and a first rotary fixing member;

[0007] The control box assembly includes a rotating connection structure and a second rotating fastener. The rotating connection structure is connected to the rotating support structure to allow the control box assembly to rotate relative to the middle frame assembly. After the second rotating fastener aligns with the first rotating fastener, the control box assembly is fixed to the middle frame assembly.

[0008] In some embodiments, the control box assembly further includes a control box housing, and the second rotating retainer includes:

[0009] A rotating plate is rotatably connected to the control box housing;

[0010] A connector, fixed to the rotating plate, is used to dock with the first rotating fixing member.

[0011] In some embodiments, the control box assembly further includes an elastic element, the two ends of which are respectively connected to the rotating plate and the control box housing. The elastic element is used to provide an elastic force to the rotating plate to ensure that the connector and the first rotating fixing member are tightly connected.

[0012] In some embodiments, the first rotating fastener and the connecting member are one or more of the following: hook and loop fastener, magnetic fastener, and snap-on slot assembly.

[0013] In some embodiments, the rotating support structure is a rotating support groove, and the rotating connection structure is a snap-fit ​​head, which snaps into the rotating support groove to allow the control box assembly to rotate relative to the middle frame assembly;

[0014] The card head is disposed at the end of the control box assembly, and the rotating support groove is disposed at the end of the middle frame assembly, so that the control box assembly can rotate relative to the middle frame assembly about its end.

[0015] In some embodiments, a locking mechanism is further included, which is disposed on the middle frame assembly and / or the control box assembly; after the second rotating fastener and the first rotating fastener have completed docking, the locking mechanism is used to further lock the control box assembly and the middle frame assembly.

[0016] In some embodiments, a connector is also included, wherein the control box assembly includes a central control board, and the connector includes:

[0017] The connector is attached to the aforementioned frame component;

[0018] A connector, connected to the central control plate, is used to rotate and insert into the bearing insert to achieve an electrical connection with the bearing insert.

[0019] In some embodiments, the support element is provided with a groove for a built-in conductive spring, and the connector is provided with a protrusion with a conductive strip;

[0020] When the connector is inserted into the support, the protrusion is embedded in the groove, so that the conductive protrusion contacts and abuts against the conductive spring, thereby realizing the electrical connection between the connector and the support.

[0021] In some embodiments, the inner walls of the groove along the second direction perpendicular to the first direction are provided with spaced conductive spring pieces, and the outer walls of the protrusion along the second direction are provided with spaced conductive protrusions. When the protrusion is rotated and inserted into the groove, the conductive protrusions and the conductive spring pieces make corresponding contact and abutment.

[0022] The distance between the two conductive spring pieces corresponding to both sides of the groove along the second direction is less than the distance between the two conductive protrusions corresponding to both sides of the protrusion along the second direction.

[0024] The first frame is used to be positioned on the first side of the LED display unit;

[0025] The second frame is used to be positioned on the second side of the LED display unit;

[0026] Two arc-shaped locks, one of which is connected at both ends to the first frame and the central control box assembly, and the other of which is connected at both ends to the second frame and the central control box assembly.

[0052] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0053] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0054] Please see Figure 1 and Figure 2 The central control box module 10 provided in this application embodiment includes a central frame assembly 11 and a control box assembly 12.

[0055] The middle frame assembly 11 includes a rotating support structure 111 and a first rotating fastener 112; the control box assembly 12 includes a rotating connection structure 121 and a second rotating fastener 122. The rotating connection structure 121 is connected to the rotating support structure 111 so that the control box assembly 12 can rotate relative to the middle frame assembly 11. After the second rotating fastener 122 and the first rotating fastener 112 are docked, the control box assembly 12 is fixed to the middle frame assembly 11.

[0056] Please see Figure 3 The rotating support structure 111 can be a rotating support groove, and the rotating connection structure 121 is a clip head. The clip head is inserted into the rotating support groove so that the control box assembly 12 can rotate relative to the middle frame assembly 11.

[0057] Specifically, the card head is located at the lower end of the control box assembly 12, and the rotating support groove is correspondingly located at the lower end of the middle frame assembly 11, so that the control box assembly 12 can rotate relative to the middle frame assembly 11 around its end.

[0058] In other words, by adopting the above-mentioned limiting rotation docking structure design, the control box assembly 12 (built-in central control plate 125) can be rotated and installed. The control box assembly 12 is installed and fixed by rotating the limiting rotation point formed by the combination of the above-mentioned clamp and the rotating support groove to a specific angle in a specified direction.

[0059] It should be noted that the control box assembly 12 in the existing system needs to be locked to the middle frame assembly 11 by the latches on both sides. This operation requires two hands to perform initial positioning during assembly and disassembly, which is cumbersome, inefficient, and difficult to meet the needs of rapid assembly and maintenance.

[0060] In contrast, the central control box module 10 provided in this application, through the cooperation of the rotating connection structure 121 and the rotating support structure 111, and the docking design of the first rotating fixing member 112 and the second rotating fixing member 122, enables the control box assembly 12 to rotate relative to the central frame assembly 11. The user only needs to complete the rotation operation of the control box assembly 12 with one hand to realize the rotation installation and fixation of the control box assembly 12, which significantly improves the assembly convenience of the control box assembly 12 and optimizes the user experience.

[0061] Please see Figure 2 The control box assembly 12 also includes a control box housing 123, and the second rotating fixing member 122 includes a rotating plate 1221 and a connecting member 1222.

[0062] The rotating plate 1221 is rotatably connected to the control box housing 123 via a rotating shaft; the connector 1222 is fixed on the rotating plate 1221 and is used to dock with the first rotating fixing member 112.

[0063] Specifically, the first rotating fixing member 112 may be a first snap-fit ​​arm (the first snap-fit ​​arm has a first snap hook structure) extending from the side wall of the middle frame assembly 11 near the control box assembly 12, and the connecting member 1222 may be a second snap-fit ​​arm (the second snap-fit ​​arm has a second snap hook structure) extending from the side wall of the rotating plate 1221 near the middle frame assembly 11.

[0064] In this way, when the control box assembly 12 is rotated relative to the middle frame assembly 11 until the second latch structure engages with the first latch structure, the docking and installation of the control box assembly 12 and the middle frame assembly 11 can be achieved.

[0065] Furthermore, by setting a rotatable rotating plate 1221, the connector 1222 can be finely adjusted in angle according to actual assembly requirements. Thus, during the rotation of the control box assembly 12 relative to the middle frame assembly 11, the connector 1222 can adaptively adjust its position to precisely align with the first rotating fixing member 112, effectively reducing assembly accuracy requirements and improving assembly efficiency and docking reliability.

[0066] Please see Figure 2 The control box assembly 12 also includes an elastic element 124, with its two ends connected to the rotating plate 1221 and the control box housing 123, respectively. The elastic element 124 is used to provide elastic force to the rotating plate 1221 to ensure that the connector 1222 and the first rotating fixing member 112 are tightly connected.

[0067] Of course, in order to ensure the stability of the connection, the number of the above-mentioned elastic element 124 and connector 1222 can be set to two. The first ends of the two elastic elements 124 are respectively connected to the lower position of the two connectors 1222, so that the rotating plate 1221 maintains the tendency of the two connectors 1222 being tightly engaged with the two first rotating fixing elements 112 respectively.

[0068] In this way, through the elastic pre-tightening effect of the elastic element 124, the connector 1222 and the first rotating fixing element 112 always maintain a tight fit after docking, effectively compensating for the fit gap caused by manufacturing tolerances or long-term use, preventing the control box assembly 12 from loosening in a vibration environment, and significantly improving the stability and vibration resistance of the connection.

[0069] In some embodiments, the first rotating fastener 112 and the connector 1222 are one or more of the following: hook and loop fastener, magnetic fastener, and snap-on slot assembly.

[0070] By adopting mature quick connection structures such as hooks, magnetic attraction, or snap-on slots, the docking method between the first rotating fixing part 112 and the connecting part 1222 can be flexibly configured according to the load requirements, disassembly and assembly frequency and cost budget of different application scenarios, which not only ensures the reliability of the connection, but also takes into account the convenience and economy of operation.

[0071] Please see Figure 1 and Figure 2 The central control box module 10 also includes a locking mechanism 13, which is disposed in the central frame assembly 11 and / or the control box assembly 12.

[0072] After the second rotating fastener 122 and the first rotating fastener 112 are docked, the locking mechanism 13 is used to further lock the control box assembly 12 and the middle frame assembly 11.

[0073] As can be seen from the above, by fitting the locking head and the rotating support groove at the end of the component, the control box component 12 can rotate and open and close with the end as the fulcrum, forming a hinge-like flip structure. Users can easily lift or lower the control box component 12 with one hand, greatly simplifying the assembly and disassembly process. Furthermore, a locking mechanism 13 is added. After the second rotating fixing member 122 and the first rotating fixing member 112 have completed their initial docking, the locking mechanism 13 provides secondary locking protection, forming a double insurance mechanism. This effectively prevents the first rotating fixing member 112 from accidentally separating from the second rotating fixing member 122 due to misoperation or external impact, significantly improving the overall structural safety and reliability.

[0074] In some embodiments, the locking mechanism 13 may be configured to include a male locking end and a female locking end, with the female locking end located on the middle frame assembly 11 and the male locking end located on the control box assembly 12. Locking of the control box assembly 12 and the middle frame assembly 11 is achieved by engaging the male locking end and the female locking end.

[0075] Please see Figure 2 The control box assembly 12 includes a central control board 125. In conventional enclosures, the central control board 125 is usually fixed to the middle frame assembly 11. During maintenance, the control box assembly 12 must be disassembled first, and then the central control board 125 must be disassembled, which involves a second disassembly. However, in this application, the central control board 125 is located in the control box assembly 12, that is, the control box assembly 12 is designed as a module with the central control board 125 built in. Disassembly can be completed in one step without the need for a second disassembly of the central control board 125, which further improves the efficiency of assembly and disassembly.

[0076] Please see Figure 2 , Figure 4 and Figure 5 The central control box module 10 also includes a connector 14, which includes a socket 141 and a plug 142. The socket 141 is connected to the central frame assembly 11; the plug 142 is connected to the central control plate 125 and is used to rotate and insert into the socket 141 to achieve electrical connection with the socket 141.

[0077] The connector 141 has a groove 1411 with a built-in conductive spring 1412; the connector 142 has a protrusion 1421 with a conductive protrusion 1422. When the connector 142 is inserted into the connector 141, the protrusion 1421 is embedded in the groove 1411, so that the conductive protrusion 1422 and the conductive spring 1412 come into contact and abut against each other, so as to realize the electrical connection between the connector 142 and the connector 141.

[0078] In other words, the connector 14 is engaged with the groove 1411 of the conductive spring piece 1412 in the socket 141 and the protrusion 1421 of the plug 142 with the conductive protrusion 1422, so that the conductive protrusion 1422 and the conductive spring piece 1412 are in elastic contact and abut against each other, so that the plug 142 and the socket 141 maintain electrical conductivity.

[0079] The use of a spring-plate-protrusion elastic contact structure instead of traditional rigid pins eliminates the problem of rigid stress concentration during insertion and removal. Simultaneously, the conductive spring 1412 provides elastic cushioning during insertion, effectively absorbing mechanical impacts and significantly reducing the risk of terminal damage, thereby improving long-term connection stability. Furthermore, the interlocking guide structure of the groove 1411 and protrusion 1421 enables rapid alignment, reducing the difficulty of insertion and removal operations. The elastic contact method also makes the insertion and removal force more gentle and controllable, avoiding mechanical damage caused by interference fits and extending the service life of the connector 14. In addition, the elastic contact between the conductive spring 1412 and the conductive protrusion 1422 forms a continuous and stable contact pressure, which, compared to the fixed contact point of rigid pins, can compensate for displacement caused by manufacturing tolerances and thermal expansion and contraction, maintaining stable electrical conductivity.

[0080] In this embodiment, the connector 142 is rotatably inserted into the support connector 141.

[0081] In other words, the connector 142 is not directly inserted into the connector 141 in a straight line, but rather it rotates along with the control box assembly 12 to achieve docking with the connector 141. This rotary plugging method changes the traditional axial straight-insertion operation mode, and completes the electrical connection through circumferential rotation.

[0082] The rotary connector can achieve progressive guidance by using the contour matching of the protrusion 1421 and the groove 1411, reducing the initial alignment accuracy requirements. At the same time, it can smoothly transition the insertion and extraction resistance during rotation, avoiding damage to the terminals caused by instantaneous impact loads, and improving the operating feel and connection reliability.

[0083] To facilitate rotational insertion and removal, the inner walls of the groove 1411 along both sides of the first direction are spaced apart from the protrusion 1421. In other words, the groove 1411 is provided with clearance space along both sides of the first direction, so that the protrusion 1421 can be rotatably inserted into or pulled out of the groove 1411.

[0084] Understandably, by defining the dimensional relationship between the groove 1411 and the protrusion 1421 in a first direction (usually the length direction), an appropriate gap is maintained between them, thereby providing rotational space for the protrusion 1421. In this way, this clearance fit eliminates the precise dimensional control required for interference fits, reducing machining accuracy requirements and manufacturing costs; simultaneously, it provides rotational freedom for the protrusion 1421, allowing for adaptive adjustment of the insertion angle, compensating for manufacturing accuracy and installation position deviations, avoiding jamming or terminal deformation caused by forced insertion, and significantly improving assembly tolerance and ease of operation.

[0085] In some embodiments, the inner walls of the groove 1411 along the second direction perpendicular to the first direction are provided with spaced conductive spring pieces 1412, and the outer walls of the protrusion 1421 along the second direction are provided with spaced conductive protrusions 1422. When the protrusion 1421 is rotated and inserted into the groove 1411, the conductive protrusions 1422 and the conductive spring pieces 1412 make contact and abut against each other in a one-to-one correspondence.

[0086] In this embodiment, multiple sets of conductive spring pieces 1412 are arranged on the inner walls of both sides of the groove 1411 in the second direction (usually the width direction), and correspondingly, multiple sets of conductive protrusions 1422 are arranged on the outer walls of both sides of the protrusion 1421, forming a double-row symmetrical contact structure. When the protrusion 1421 is rotated and inserted into the groove 1411, the conductive protrusions 1422 on both sides synchronously contact the corresponding conductive spring pieces 1412 one after another and elastically abut against each other.

[0087] This double-row symmetrical contact structure establishes multiple parallel electrical channels simultaneously in a single insertion action, significantly improving the current carrying capacity and signal transmission density of connector 14; the progressive contact characteristics during the rotation insertion process enable each group of contacts to conduct sequentially, and the symmetrical layout also ensures a balanced distribution of contact pressure, enhancing mechanical stability and vibration resistance.

[0088] It should be noted that the first direction mentioned above can be as follows: Figure 4 The X-axis direction is shown, and the second direction can be as follows: Figure 4 The Y-axis direction is shown.

[0089] In this embodiment, the distance between the two conductive spring pieces 1412 corresponding to both sides of the groove 1411 along the second direction is less than the distance between the two conductive protrusions 1422 corresponding to both sides of the protrusion 1421 along the second direction.

[0090] In other words, the spacing between the spring tabs is slightly smaller than the spacing between the protrusions. As a result, when the protrusion 1421 is inserted into the groove 1411, the conductive protrusions 1422 on both sides exert an outward expanding compressive force on the conductive spring tab 1412, while the spring tab, due to the spacing limitation, generates a reverse elastic clamping force. This interference fit design allows the conductive spring tab 1412 to form a ring-shaped elastic clamping around the conductive protrusion 1422, generating a continuous and stable positive contact pressure, effectively overcoming the problem of contact resistance fluctuations. Furthermore, this elastic clamping mechanism can automatically compensate for contact slack caused by wear, significantly improving the reliability of the electrical connection.

[0091] Understandably, the connector 142, as the male end, replaces the traditional pin with a raised conductive block (a protrusion 1421 with a conductive protrusion 1422); the receiver 141, as the female end, replaces the traditional socket with a groove 1411 containing a conductive spring 1412. When the control box assembly 12 is locked, the conductive protrusion 1422 presses against the conductive spring 1412 to achieve conductivity. When the control box assembly 12 is flipped open, the two parts disengage directly, eliminating the risk of the traditional pin breaking in the socket during flipping.

[0092] In some embodiments, the connector 142 includes a fixing base 1423, which is spaced apart from the protrusion 1421 in the insertion direction. Two rows of spring pins 1426 are provided between the fixing base 1423 and the protrusion 1421. Two rows of conductive protrusions 1422 are provided, protruding from the protrusion 1421, and the conductive protrusions 1422 and spring pins 1426 are connected in a one-to-one correspondence. In this way, a fixing base 1423 is added to the connector 142, and an elastic electrical connection is achieved between the fixing base 1423 and the conductive protrusions 1422 on the protrusion 1421 through the array of spring pins 1426.

[0093] The connector 142 is configured in such a way that the elastic deformation capability of the spring pin 1426 provides the axial floating degree of freedom for the bump 1421, so that the bump 1421 can adaptively adjust its position during the insertion process to match the groove 1411 of the connector 141, reducing the rigid alignment requirements; at the same time, the spring pin 1426, as an intermediate elastic link, can absorb the mechanical impact and vibration during the insertion and removal process, protecting the rear circuit board from stress damage.

[0094] To facilitate limiting the insertion stroke, the connector 141 is also provided with a first limiting structure 1415, and the connector 142 is also provided with a second limiting structure 1425. When the connector 142 is inserted into the connector 141, the first limiting structure 1415 and the second limiting structure 1425 come into contact to limit the stroke of the connector 142.

[0095] In other words, a first limiting structure 1415 and a second limiting structure 1425 are respectively provided on the receiving plug 141 and the plug-in 142 to cooperate with each other. When the plug-in 142 is inserted to the designed depth, the two limiting structures abut against each other to prevent further displacement. This mechanical limiting structure provides a clear indication of the insertion position, preventing terminal overpressure deformation or housing damage caused by over-insertion.

[0096] Of course, based on the actual dimensions of the support 141 and the connector 142, the dimensions of the first limiting structure 1415 and the second limiting structure 1425 can be precisely designed to ensure that the conductive protrusion 1422 and the conductive spring 1412 are in the optimal contact area, avoiding poor contact caused by insufficient insertion depth or plastic deformation of the spring caused by excessive insertion depth.

[0097] In some embodiments, the support 141 and the connector 142 may adopt a double-layer annular shell nesting structure to achieve the functions of limiting and protecting.

[0098] Specifically, the support member 141 includes a first annular shell 1413 and a base plate 1414 connected to the first annular shell 1413. A groove 1411 is provided in the first annular shell 1413, and the base plate 1414 has an edge protruding from the first annular shell 1413 to form a first limiting structure 1415. The connector 142 includes a second annular shell 1424 surrounding the protrusion 1421, and a second limiting structure 1425 is provided in the second annular shell 1424. When the connector 142 is inserted into the support member 141, the second annular shell 1424 is fitted into the first annular shell 1413 until the first limiting structure 1415 and the second limiting structure 1425 come into contact.

[0099] As can be seen, the first annular shell 1413 of the support member 141 carries the groove 1411 and the conductive spring piece 1412, and the outer edge of its base plate 1414 forms the first limiting structure 1415; the second annular shell 1424 of the connector 142 protects the protrusion 1421, and its end face or inner step forms the second limiting structure 1425. During insertion, the second annular shell 1424 slides in along the outer wall of the first annular shell 1413 until the two limiting structures abut.

[0100] The above-mentioned double-layer shell nesting forms a circumferentially enclosed insertion guide cavity, which significantly improves the physical protection of the internal conductive structure and prevents dust and foreign objects from entering. The annular contact surface allows the plug 142 to be inserted at any angle in the circumference, and combined with the aforementioned rotational insertion characteristics, it enables blind insertion operation. The shell end face limit provides a large area of ​​uniform load bearing, disperses the impact force, and protects the precision conductive components.

[0101] Please see Figures 6 to 10 , Figures 6-10 The diagram shows the clearance situation at the extreme positions of the spring-loaded connector and the rotary control box during rotation: (The diagram is incomplete and requires further context to be fully translated.) Figures 6-10 As can be seen, during the rotation of the control box assembly 12 around the rotation support point, the upper and lower plugs 142 have good clearance at their extreme positions, preventing interference with the support plug 141 and facilitating the rotation of the control box assembly 12. Specifically, there is a certain gap between the protrusion 1421 of the plug 142 and the upper and lower end faces of the groove 1411 of the support plug 141, ensuring that when the control box assembly 12 is flipped, the male end will not interfere with the end face of the female end, thus preventing it from being removed. Simultaneously, the spring-loaded flexible contact method avoids the bending of conventional pins during the rotation of the control box assembly 12.

[0102] It can be seen that during the rotation of the control box assembly 12 around the rotation support point, the upper and lower plugs 142 are well cleared at their extreme positions, and no interference is caused.

[0103] The working principle of the central control box module 10 provided in this embodiment is as follows:

[0104] First, hold the control box assembly 12 with one hand and insert its protruding bottom part (i.e., the rotating connection structure 121) into the rotating support point groove (i.e., the rotating support structure 111). At this time, the control box assembly 12 can be regarded as a simple hinge support. Apply a counterclockwise torque to the control box assembly 12 until the second rotating fixing member 122 hooks onto the first rotating fixing member 112 on the central control box module 10. At this time, the control box assembly 12 is initially locked. Then, fasten the remaining latches around the control box assembly 12 to complete the installation. Conversely, unlock the latches around the control box assembly 12 and the second rotating fixing member 122, apply a clockwise torque to the control box assembly 12, and after the control box assembly 12 rotates around the rotating support point at a certain angle, it can be taken out to the right to complete the disassembly of the control box assembly 12.

[0105] In summary, this application, by designing a rotating mounting structure for the control box assembly 12, eliminates the traditional operation of initially positioning the control box assembly 12 using both hands, and solves the problem of secondary disassembly when maintaining the central control board 125, which requires first disassembling the control box assembly 12 and then the central control board 125. In addition, the rotating control box assembly 12 is more convenient to disassemble and the force applied is easier to control, improving the efficiency of disassembling and assembling the control box assembly 12 and the user experience. At the same time, it has a significant cost advantage and is more competitive in the LED market.
