[0036] The realization of the purpose, functional features and advantages of the present invention will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0039] The main purpose of the present invention is to provide a box 100 with changeable modules, so as to solve the problem in the prior art that the box of the lamp pole screen cannot adapt to different LED module sizes and has poor versatility.

[0040] See also Figures 1 to 11 In one embodiment of the present invention, a box 100 with a changeable module includes a box frame 110, an inner wall of the box frame 110 is provided with a mounting groove 110a, and the mounting groove 110a extends along the thickness direction of the box frame 110; a mounting plate 120, the mounting plate 120 has a front and a back, the front of the mounting plate 120 is used to install the LED module, and the back of the mounting plate 120 is provided with a clamping block 121, which is embedded in the mounting groove 110a so that the mounting plate 120 can be detachably installed on the box frame 110.

[0041] In the technical solution of the present invention, the box 100 with a changeable module includes a box frame 110 and a mounting plate 120. The LED module is installed on the front of the mounting plate 120. The inner wall of the box frame 110 is provided with a mounting groove 110a, and the mounting groove 110a extends along the thickness direction of the box frame 110; the mounting plate 120 is embedded in the mounting groove 110a through a clamping block 121 provided on the back, and is then detachably installed on the box frame 110. It can be understood that the box frame 110 and the mounting plate 120 in the present technical solution are detachably connected, and the box can be adapted to LED modules of different sizes by replacing different mounting plates 120, thereby realizing the reuse of the box. The mounting plate 120 is engaged with the mounting groove 110a on the frame of the box frame 110 through the snap-in block 121, thereby sealing the inner wall of the box frame 110 and achieving a waterproof effect to a certain extent. In addition, due to the use of a non-welded structure, the materials of the box frame 110 and the mounting plate 120 can be the same or different, thereby realizing the use of mounting plates 120 of different materials according to different usage scenarios, thereby flexibly controlling production costs.

[0042] Specifically, in this embodiment, the box frame 110 is a rectangular parallelepiped frame, and the box frame 110 has a unidirectional opening accommodating cavity, which is also in the shape of a rectangular parallelepiped. Figures 4 and 5 The inner wall of the accommodating cavity is provided with a circle of grooves, and the groove near the side of the accommodating cavity opening is folded outward to form a mounting groove 110a, which extends along the thickness direction of the box frame 110. The mounting groove 110a is used to install the mounting plate 120; see again Figures 6 and 7The mounting plate 120 is a rectangular plate whose shape matches the accommodating cavity. The front of the mounting plate 120 is used to install the LED module. The periphery of the back of the mounting plate 120 is bent to form a circle of clamping blocks 121. During installation, the back of the mounting plate 120 faces the mounting groove 110a, and the clamping blocks 121 are embedded in the mounting groove 110a. Then, screws are passed through the mounting plate 120 and the mounting groove 110a in sequence to lock the mounting plate 120 on the box frame 110. Due to the structure of the clamping blocks 121, when the mounting plate 120 is installed in the mounting groove 110a, it can be closed to prevent external rainwater from entering the accommodating cavity from the gap on the side. After the LED module is installed on the front of the mounting plate 120, the opening of the accommodating cavity of the box frame 110 is completely closed, preventing waterproof rainwater from seeping into the box frame 110 from the front. It is understandable that in some other embodiments, the box frame 110 and the mounting plate 120 can also adopt other detachable installation methods, such as snaps, magnets, etc., and the shapes of the box frame 110 and the mounting plate 120 can also be other, such as square, oval, bar, other irregular polygons such as trapezoids, etc., as long as the box frame 110 and the mounting plate 120 can be detachably connected. The embodiments of the present invention are not limited to this, and the above are all within the scope of protection of the present invention.

[0043] Furthermore, in an optional embodiment, a line inlet 110c connected to the accommodating cavity is respectively provided on the left and right sides of the box frame 110, and the external cable enters the accommodating cavity from the line inlet 110c to electrically connect the electrical components in the accommodating cavity. The inner side of the two side edges of the box frame 110 is also provided with a line inlet water baffle 160, which covers the line inlet 110c. The line inlet water baffle 160 has a channel along the vertical direction of the box frame 110. When the cable enters the box frame 110 from the line inlet 110c, it will be routed along the channel. At this time, the line inlet water baffle 160 will force the cable to bend upward. With this arrangement, when rainwater or the like enters the box frame 110, it will naturally flow back along the cable, and will not enter the accommodating cavity to cause damage to the internal components. In addition, a row of nut columns 170 are respectively provided in the grooves at the top and bottom of the box frame 110. The nut columns 170 are used to connect to external fixing brackets so that the box 100 of the changeable module can be fixed at the required installation location. During installation, the screws are passed through the through holes on the bracket and screwed into the screw holes of the nut columns 170 to complete the installation. Of course, in some other embodiments, other methods can also be used to fix the box 100 of the changeable module, such as snaps, magnetic structures, clamps, etc., which depend on the actual situation and are not limited here.

[0044] See also Figures 1 to 3Furthermore, in one embodiment of the present invention, the box frame 110 includes a face frame 111 and a cover plate 112, the cover plate 112 can be movably covered on the face frame 111, the mounting groove 110a is provided on the inner wall of the face frame 111, and the mounting plate 120 can be detachably mounted on the side of the face frame 111 away from the cover plate 112 through the mounting groove 110a.

[0045] Specifically, in this embodiment, the cabinet frame 110 includes a face frame 111 and a cover plate 112. The face frame 111 is an open frame with a mounting slot 110a defined within its inner edge. The mounting plate 120 is removably mounted to the face frame 111 via the mounting slot 110a. The face frame 111 and the cover plate 112 are connected by a hinge, forming a cabinet structure with a door. The cover plate 112 can be opened and closed. When the cover plate 112 is placed over the face frame 111, the face frame 111 and the cover plate 112 form a single-opening storage chamber. In particular, the cover plate 112 is provided with a triangular lock 113, which locks the face frame 111 and the cover plate 112 together. This arrangement allows staff to easily open the cover plate 112 to inspect electrical components within the cabinet and perform wiring and debugging work. Of course, the connection method between the face frame 111 and the cover plate 112 can also adopt other structures, for example, a sliding door structure, a magnetic door structure, a snap-on fastening, etc. The embodiments of the present invention are not limited thereto, and the above are all within the scope of protection of the present invention.

[0046] See also Figures 2 to 3 Furthermore, in one embodiment of the present invention, a fan assembly 140 is provided on a surface of the cover plate 112 facing the mounting plate 120. The cover plate 112 defines a first ventilation opening 112a, and the fan assembly 140 is in communication with the first ventilation opening 112a. Furthermore, a dust screen assembly 150 is provided on a surface of the cover plate 112 facing the mounting plate 120. The cover plate 112 defines a second ventilation opening 112b, and the dust screen assembly 150 is in communication with the second ventilation opening 112b.

[0047] Specifically, in this embodiment, a fan assembly 140 is provided on the surface of the cover plate 112 facing the mounting plate 120. The fan assembly 140 is provided above the cover plate 112 along the vertical direction of the box frame 110, that is, close to the top of the box frame 110. The air outlet of the fan assembly 140 is provided toward the mounting plate 120 so that the fan assembly 140 can effectively dissipate heat from the LED module. Correspondingly, three rows of first vents 112a are provided at this position of the cover plate 112, forming a structure similar to shutters. The fan assembly 140 covers the first vents 112a and is connected thereto for ventilation and heat dissipation. Due to the characteristics of outdoor use of lamp pole screens or other LED screen equipment, especially in summer or when running for a long time, the internal temperature may rise to above 60°C. By providing the fan assembly 140, the temperature inside the box can be quickly reduced to prevent performance degradation or damage to the equipment due to overheating.

[0048] In an optional embodiment, the surface of the cover plate 112 facing the mounting plate 120 is further provided with a dust screen assembly 150. The dust screen assembly 150 is positioned below the cover plate 112, i.e., near the bottom of the housing frame 110. Correspondingly, the cover plate 112 is provided with three rows of second vents 112b at this location, forming a structure similar to a Venetian blind. The dust screen assembly 150 covers and communicates with the second vents 112b for ventilation and heat dissipation. Since dust cannot be prevented from entering the housing when the device is placed in an external environment for a long time, and since fine particles such as dust and sand will settle, positioning the dust screen assembly 150 at the bottom can effectively reduce dust accumulation within the housing.

[0049] It should be noted that the number of first vents 112a and second vents 112b can be other than shutters, and their forms can also be forms other than louvers, such as grille-type air outlets, mesh-type air outlets, etc., depending on actual circumstances and are not limited here. It can be understood that the provision of fan assembly 140 and dust screen assembly 150 can effectively extend the service life of the equipment and reduce equipment maintenance costs.

[0050] See also Figure 10 Furthermore, in one embodiment of the present invention, the fan assembly 140 includes a fan bracket 141, a fan pressure plate 143, a fan 142 and an air outlet water shield plate 144. The fan bracket 141, the fan 142 and the fan pressure plate 143 are sequentially installed on the surface of the cover plate 112 facing the mounting plate 120. The air outlet water shield plate 144 has an opening and is connected to the fan 142. The fan 142 is connected to the first ventilation port 112a through the opening of the air outlet water shield plate 144.

[0051] Specifically, in this embodiment, three fans 142 are arranged side by side on the cover plate 112. The fans 142 have air outlets. When installing, first install the fan bracket 141 on the surface of the cover plate 112 facing the mounting plate 120, then install the fans 142 and the fan pressing plate 143 in sequence. The fan pressing plate 143 sandwiches the fans 142 and is fixed to the fan bracket 141 by screws. Figure 8 The air outlet shield 144 is a trapezoidal sheet metal cover, positioned below the fan 142 and covering the first vent 112a. The bottom of the air outlet shield 144 is a sloped surface, flush with the bottommost first vent 112a. The side opposite the slope has three openings, each connected to the air outlets of the three fans 142. Air generated by the fans 142 flows out of the air outlets, then through the openings in the air outlet shield 144, through the interior space of the air outlet shield 144, and finally out of the first vent 112a, achieving air circulation and heat dissipation within the cabinet. The perimeter of the air outlet shield 144 is coated with waterproof glue to further enhance its sealing. The trapezoidal air deflector 144 is used. When encountering windy and rainy weather, rainwater will drift upward and enter the interior of the box through the first vent 112a. Because the air deflector 144 has a slope, the slope can act as a guide, allowing rainwater to flow back along the slope, preventing rainwater from entering the interior of the box and damaging internal components. It should be understood that the number of fans 142, the arrangement of fans 142, and the form of the air deflector 144 are not limited to the examples shown in this embodiment; as long as the fans 142 are connected to the first vent 112a, any suitable method will be used.

[0052] See also Figure 11 Furthermore, in one embodiment of the present invention, the dustproof net assembly 150 includes a dustproof net 151, a dustproof net pressure plate 152 and an air inlet water deflector 153. The air inlet water deflector 153 is arranged on the surface of the cover plate 112 facing the mounting plate 120. The air inlet water deflector 153 has an opening. The dustproof net 151 and the dustproof net pressure plate 152 are sequentially covered on the opening of the air inlet water deflector 153. The dustproof net 151 is connected to the second ventilation port 112b through the opening of the air inlet water deflector 153.

[0053] Specifically, in this embodiment, the dustproof net 151 is provided with a plurality of mesh holes. Figure 8The air inlet water baffle 153 is a trapezoidal sheet metal cover that covers the second vent 112b. The bottom of the air inlet water baffle 153 is an inclined surface that is flush with the bottom-most second vent 112b. The side opposite the inclined surface is an opening. The dust screen 151 and the dust screen pressure plate 152 are sequentially laid on the opening and fixed with screws. With the trapezoidal air inlet water baffle 153, when encountering wind and rain, rainwater will float upward and enter the interior of the box through the second vent 112b. Because the air inlet water baffle 153 has an inclined surface, it can act as a guide, allowing rainwater to flow back along the inclined surface, preventing rainwater from entering the box and damaging internal components. In addition, fine particles such as dust and sand that enter the box through the second vent 112b or other open structures will also be collected by the inclined surface, making it easier to clean. It can be understood that the form of the air inlet water deflector 153 is not limited to the example in this embodiment, as long as the dust net 151 is connected to the second ventilation port 112b.

[0054] See also Figures 8 and 9 Furthermore, in one embodiment of the present invention, a waterproof rubber ring 130 is included. The waterproof rubber ring 130 is detachably clamped in the mounting groove 110a by the mounting plate 120, and the outer wall of the waterproof rubber ring 130 is respectively in contact with the clamping block 121 and the groove wall of the mounting groove 110a.

[0055] Specifically, in this embodiment, the box frame 110 also includes a waterproof rubber ring 130, which is a circle of square-shaped rubber rings that match the mounting groove; during installation, the waterproof rubber ring 130 is first installed in the mounting groove 110a, and then the mounting plate 120 is installed. When the clamping block 121 of the mounting plate 120 is embedded in the mounting groove 110a, the waterproof rubber ring 130 will be squeezed. It can be understood that the waterproof rubber ring 130 is installed between the clamping block 121 and the mounting groove 110a. After the mounting plate 120 is fixed by screws, the waterproof rubber ring 130 can be further pressed into the mounting groove 110a to form a sealed environment. Such an arrangement can improve the waterproof performance of the box frame 110, ensure that LED screen equipment such as lamp pole screens can work normally under adverse outdoor weather conditions such as rain and typhoons, and prevent moisture from entering the interior of the box frame 110, thereby avoiding damage to internal electrical components.

[0056] See also Figures 4 and 5 Furthermore, in one embodiment of the present invention, a water outlet 110b communicating with the outside is opened on the inner wall of the accommodating cavity, so that water entering the accommodating cavity from the outside can be guided to the water outlet 110b through the installation groove 110a and discharged.

[0057] Specifically, in this embodiment, the groove at the bottom of the box frame 110 is provided with a plurality of water outlet holes 110b that communicate with the outside. Since the mounting groove 110a is formed by folding the notch of the groove, the mounting groove 110a also has a certain diversion function. On rainy days, rainwater will flow along the mounting groove 110a to the bottom water outlet holes 110b due to gravity and be discharged. Furthermore, the outer side surface of the bottom of the box frame 110 is also provided with a gasket 180. The gasket 180 does not at least partially block the water outlet holes 110b to prevent the water outlet holes 110b from being unable to drain. The periphery of the gasket 180 is coated with waterproof glue to prevent water from accumulating when heavy rainwater is excessive and seeping into the interior of the box frame 110 along the welds. When the box 100 of the changeable module is installed on the external bracket, the gasket 180 acts to create a certain gap between the bottom of the box frame 110 and the external bracket. By setting the water outlet 110b, on the one hand, the external rainwater can be diverted to the water outlet 110b for discharge through the diversion effect of the installation groove 110a; on the other hand, due to the inlet water baffles 160 set on the left and right sides of the box frame 110, the cables are arranged along the vertical direction of the box frame 110, so that when rainwater flows along the cable, it will naturally flow back to the water outlet 110b for discharge, and will not enter the interior of LED screen equipment such as lamp pole screens, thereby playing a waterproof role.

[0058] See also Figure 3 Furthermore, in one embodiment of the present invention, a transverse reinforcing rib 122 and a vertical reinforcing rib 123 are provided on the back of the mounting plate 120 , and the transverse reinforcing rib 122 and the vertical reinforcing rib 123 are cross-arranged.

[0059] Specifically, in this embodiment, vertical reinforcing ribs 123 and transverse reinforcing ribs 122 are arranged in a cross-sectional pattern on the back of the mounting plate 120. Each of the vertical and transverse reinforcing ribs 123 and 122 has a notch located at their intersection. The notches are interlocked with each other, ensuring that the vertical and transverse reinforcing ribs 123 and 122 are at the same level when cross-mounted on the mounting plate 120. The provision of the vertical and transverse reinforcing ribs 123 and 122 improves the overall strength of the mounting plate 120, enabling it to better support the weight of the LED modules. In the event of inclement weather, the rib design also helps absorb and disperse impact forces acting on the mounting plate 120, enhancing the overall housing structure's resistance to harsh natural environments such as wind and rain. This makes the product more reliable over the long term and reduces the frequency of maintenance and replacement.

[0060] See also Figures 1 to 11This embodiment provides a lamp pole screen, including several LED modules; the above-mentioned changeable module box 100, the front of the mounting plate 120 is divided into several areas matching the size of the LED modules, and the LED modules are installed on the areas so that several LED modules are spliced to form an LED display screen; a system card is provided on the mounting plate 120 for controlling the LED display screen; and a power supply is provided on the mounting plate 120.

[0061] Specifically, in this embodiment, the housing 100 of the changeable module is applied to the lamp pole screen (the overall structure of the lamp pole screen and the LED module are not shown in the accompanying drawings). The lamp pole screen includes several LED modules, the housing 100 of the changeable module, a system card and a power supply. The housing 100 of the changeable module also includes a power supply fixing plate 300 and a system card fixing plate 200. The power supply fixing plate 300 and the system card fixing plate 200 are fixed to the back of the mounting plate 120 by screws. The power supply is installed on the power supply fixing plate 300 and is used to convert external AC power into DC power required by the lamp pole screen and provide stable power to various parts of the display screen. The stable power supply can ensure the normal operation of the lamp pole screen and extend its service life; the system card includes a receiving card and a sending card for receiving, processing and sending control signals. The system card controls the brightness and color of each LED module on the lamp pole screen to form images and text. It is also responsible for processing the refresh rate, brightness control, color correction, etc. of the lamp pole screen to ensure the quality and consistency of the display effect. The system card can receive data by wire or wireless means. For further information, see Figure 1 The front of the mounting plate 120 is divided into several areas, each of which is a rectangular frame of the same size. The vertical reinforcement ribs and the horizontal reinforcement ribs 122 are arranged crosswise on the frame. Each area surrounded by the frame can be installed with one LED module.
