Description

Technical Field

[0001] This utility model relates to the field of display module technology, and in particular to a display module that is easy to maintain. Background Technology

[0002] With the rapid development of electronic products, display modules are increasingly widely used in various devices, especially in televisions, computer monitors, and mobile devices. The performance of the display module directly affects the overall user experience, with heat dissipation being particularly crucial. In the design of display modules, heat dissipation holes are typically provided on the side walls of the casing to improve the efficiency of internal heat dissipation, thereby ensuring the stability and reliability of the display module under high-load operating conditions.

[0003] In existing technologies, to prevent external contaminants such as dust and debris from entering the display module, dust filters are typically installed at the heat dissipation holes. To ensure dust protection, these filters are usually multi-layered or have two sides. However, with prolonged use, dust easily adheres to the outside of the filter, reducing the heat dissipation area and affecting heat dissipation. Currently, dust filters on display module housings are mainly installed using either magnetic or screw fixation. Magnetic installation has poor stability and is prone to causing the filter to fall off; while screw fixation is inconvenient for disassembly and cleaning, making the dust filters on current display module housings difficult to clean. Therefore, a display module that is easy to maintain is proposed. Utility Model Content

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides, for example Figures 1-4 The illustrated display module, which is easy to maintain, includes a housing 100. A display module 101 is embedded in the front of the housing 100. A heat dissipation hole 102 is provided on the side wall of the housing 100. A dustproof mesh 200 is externally fitted with an outer shell component. A knob rod 207 is movably connected to both ends of the outer shell component. A return spring 211 is provided between the knob rod 207 and the outer shell component. A protrusion 208 is fixedly connected to the outer end of the knob rod 207. A stepped groove 103 is provided on the side wall of the housing 100, located on one side of the heat dissipation hole 102. The stepped groove 103 is adapted to the end faces of the knob rod 207 and the return spring 211. Installation is achieved by installing the dustproof mesh 200 inside the outer shell component, allowing the outer shell component to snap into the heat dissipation hole 102 on the side wall of the housing 100. Then, the knob rod 207 and the protrusion 208 on the outer shell component are engaged. The combined use of block 208 and return spring 211 allows the end of knob rod 207 with return spring 211 to be inserted into the stepped groove 103 on the side wall of housing 100. Knob rod 207 drives protrusion 208 to rotate, and with the elastic thrust provided by return spring 211, the end face of protrusion 208 can abut against the inner wall of stepped groove 103. This fixes the outer casing in the position of the side wall of housing 100. When disassembling, simply rotate knob rod 207 to rotate protrusion 208 to the position where it exits stepped groove 103. At this time, knob rod 207 and protrusion 208 will automatically exit from stepped groove 103 by the elastic thrust of return spring 211. The user can simply pull out the outer casing. The operation is simple and convenient, making the cleaning of dust screen 200 easier.

[0027] The outer casing includes a mounting cover 201 and an end cap 202. A dustproof mesh 200 is fixedly disposed inside the mounting cover 201, which is movably inserted into the heat dissipation hole 102. The end cap 202 is located on the side of the mounting cover 201 away from the casing 100. A snap-fit ​​structure is provided between the end cap 202 and the mounting cover 201, allowing the end cap 202 to be fixedly snapped into the mounting cover 201. A width difference exists between the end cap 202 and the mounting cover 201 at their midpoint to accommodate the dustproof mesh 200 within the mounting cover 201. The dust filter 200 is tightly attached to the side wall of the end cover 202, which ensures the stability of the dust filter 200 inside the housing and prevents the dust filter 200 from being pulled out directly from the front of the housing. This prevents the dust filter 200 from accidentally falling off inside the housing. Furthermore, the snap-fit ​​structure between the mounting cover 201 and the end cover 202 allows for the detachable connection between the end cover 202 and the mounting cover 201. This exposes the port of the mounting cover 201, allowing the dust filter 200 to be removed from its interior for separate cleaning, which helps improve the cleaning quality.

[0028] Furthermore, the dustproof nets 200 are arranged in two parallel intervals. Magnetic insulating sleeves 205 are fixedly connected to both ends of the opposite side of each dustproof net 200. Magnets 206 that attract each other are fixedly embedded on the opposite side of each pair of adjacent magnetic insulating sleeves 205. The dustproof nets 200 are configured as a double-layer structure, which improves the dustproof effect. The magnetic insulating sleeves 205 and magnets 206 allow for direct assembly and disassembly between adjacent dustproof nets 200, facilitating cleaning of the opposite side of the two dustproof nets 200 and improving cleaning quality. This also allows for rapid assembly and is convenient to use. The snap-fit ​​structure includes a U-shaped positioning frame 203 and a positioning protrusion 204. The U-shaped positioning frame 203 is fixedly connected to the side of the end cap 202 near the mounting cover 201. The positioning protrusion 204 is located on the outer wall of the mounting cover 201 near the end cap 202 and is connected to the mounting cover 201. 1. The unibody design features a slidable connection between the outer wall of the positioning protrusion 204 and the inner side of the U-shaped positioning frame 203. The mounting cover 201 is slidably engaged with the U-shaped positioning frame 203 on the end cover 202 via the positioning protrusion 204. Then, by utilizing the stepped shape of the inner wall of the heat dissipation through hole 102, the mounting cover 201 and the U-shaped positioning frame 203 can be engaged into the stepped groove 103. This achieves blocking and limiting of the port between the positioning protrusion 204 and the U-shaped positioning frame 203, ensuring a stable connection between the mounting cover 201 and the end cover 202. The mounting cover 201 and the end cover 202 can only be disassembled and separated after being pulled out of the heat dissipation through hole 102. This not only ensures the stable installation of the outer shell at the heat dissipation through hole 102, but also makes the disassembly and separation between the mounting cover 201 and the end cover 202 more convenient, thereby improving the ease of disassembling and cleaning the dustproof mesh 200 separately.

[0029] It should be noted that a hollow tube 209 is fixedly connected to the end of the end cap 202. The outer wall of the knob rod 207 is slidably connected to the middle of the hollow tube 209. A blocking ring 210, which is fixed to the outer wall of the knob rod 207, is slidably connected inside the hollow tube 209. A return spring 211 is located between the blocking ring 210 and the hollow tube 209 on opposite sides. An annular groove is provided on the side of the stepped groove 103 away from the outer wall of the housing 100. The depth of the annular groove is adapted to the width of the protrusion 208. After the outer shell is installed to the position of the heat dissipation hole 102 on the side wall of the housing 100, simply press the knob rod 207 inward manually to move the protrusion 208 to the concave position inside the stepped groove 103. Then, by rotating the knob rod 207... By engaging the protrusion 208 into the recessed extension of the stepped groove 103, the protrusion 208 and the stepped groove 103 are axially limited. Combined with the elastic thrust provided by the return spring 211, the protrusion 208 and the inner wall of the stepped groove 103 are kept in close contact. This ensures the stability of the housing component installed on the side wall of the housing 100. When unlocking and disassembling, the user only needs to rotate the knob 207 to return the protrusion 208 to its initial position, and the knob 207 and the protrusion 208 can be pulled out from the stepped groove 103 together. This achieves the purpose of quick unlocking and makes the disassembly and assembly of the housing component on the side wall of the housing 100 more convenient, thereby facilitating the cleaning of the dustproof mesh 200 inside the housing component.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
