Description

Technical Field

[0001] This invention belongs to the field of electrical equipment technology, and more specifically, relates to an easy-to-maintain dustproof panel structure and chassis. Background Technology

[0002] Common power supply module chassis typically use a single-piece front panel that integrates the fan shroud and display, which is then fixed to the power supply chassis with bolts. This approach is simple in structure and low in cost.

[0003] In a multi-machine parallel installation configuration, the installation gap between adjacent chassis is narrow. When it is necessary to remove the dust cover for maintenance or to inspect the internal components of the chassis, the removal of the integrated front panel is limited by the space of the adjacent chassis, making panel removal difficult. This not only reduces the efficiency of maintenance and inspection, but may also cause collision damage to the chassis or adjacent equipment due to insufficient operating space during the disassembly process. Summary of the Invention

[0004] The purpose of this invention is to provide an easy-to-maintain dustproof panel structure and chassis, which aims to solve the problem of inconvenient maintenance of integrated front panels.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is: to provide an easy-to-maintain dustproof panel structure, comprising: The display panel has an upper end that snaps into the chassis body and a lower end that has a mounting part that is detachably connected to the chassis body. The thickness of the mounting part is less than the thickness of the display panel, and an installation area is formed on the outer side of the mounting part. A dustproof panel, the upper end of which covers the outside of the mounting part and extends into the mounting area, the upper part of which is provided with a connecting part that engages with the mounting part; the lower end of which is detachably connected to the chassis body. The dustproof panel works in conjunction with the display panel to seal the front port of the chassis body.

[0006] The beneficial effects of the easy-to-maintain dustproof panel structure provided by this invention are as follows: Compared with the prior art, the prior art mostly adopts an integrated easy-to-maintain dustproof panel structure, with the display installed on one side of the easy-to-maintain dustproof panel structure and the dustproof mesh set on the other side. During inspection and maintenance, the dustproof mesh requires more frequent maintenance, while the display requires less frequent maintenance. The two are integrated and installed on the same easy-to-maintain dustproof panel structure. Every time the dustproof mesh is maintained, the entire panel needs to be removed. Frequent removal of the display part will cause the internal circuits of the display to be pulled, causing damage to the circuits and affecting the service life of the display part.

[0007] This application takes into account the different maintenance frequencies of the monitor and the dustproof panel, and proposes to divide the easily maintainable dustproof panel structure into two parts: one part is the display panel, in which the monitor is installed; the other part is the dustproof panel, which includes a dust cover for dust protection. When the dustproof panel needs to be removed for maintenance, it can be removed directly, and only the dustproof part needs maintenance, avoiding the need for frequent monitor removal which would affect the working life of the display panel.

[0008] Furthermore, when the display panel and dustproof panel are installed separately, the display panel, as an independent and easy-to-maintain dustproof panel structure, is directly connected to the chassis, which can improve the dustproof effect of the monitor and other structures.

[0009] During installation, both the display panel and the dustproof panel are detachably connected to the chassis body. The display panel has a downward protruding mounting part at the bottom, and the upper part of the dustproof panel covers the outside of the mounting part. By overlapping, the connection gap between the two is blocked. The connecting part on the inside of the dustproof panel is engaged with the mounting part to fix the upper part and block the gap.

[0010] The dustproof panel structure provided by this invention is easy to maintain. Compared with the prior art, when maintenance is required, only the dustproof panel needs to be removed. Removal is convenient and avoids the problem of limited space in adjacent chassis restricting the disassembly of the entire panel, thus improving maintenance efficiency. The overlapping fit between the mounting part and the upper end of the dustproof panel ensures precise assembly and connection between the dustproof panel and the display panel, reducing the gap at the joint and improving the sealing effect.

[0011] As another embodiment of this application, it also includes: The lower locking structure includes a snap-fit ​​hole at the lower end of the chassis body and a snap-fit ​​buckle at the lower end of the dustproof panel. The snap-fit ​​buckle is inserted into the snap-fit ​​hole in the front-back direction to limit the displacement of the dustproof panel in the left-right and up-down directions. The upper locking structure includes a positioning protrusion on the lower end surface of the mounting part and a limiting hole on the connecting part. The positioning protrusion protrudes downward and engages with the limiting hole in a corresponding manner to limit the displacement of the dustproof panel in the front-back direction.

[0012] In another embodiment of this application, the positioning protrusion includes: The snap-fit ​​part is connected to the lower end face of the mounting part, and the snap-fit ​​part is adapted to the limiting hole; The guide portion is connected to the lower end of the snap-fit ​​portion. The inner side of the guide portion is provided with a guide surface. The guide surface is inclined from top to bottom and outward, so that the limiting hole can pass smoothly through the guide portion and snap with the snap-fit ​​portion during the process of the dustproof panel flipping and snapping around the snap-fit ​​buckle.

[0013] As another embodiment of this application, it also includes: The auxiliary locking structure includes multiple positioning posts located inside the dustproof panel and multiple positioning holes opened on the chassis body. The ends of the positioning posts extend into the positioning holes and engage with them.

[0014] In another embodiment of this application, the thickness of the mounting portion is less than the thickness of the display panel, and the upper end of the dustproof panel covers the outside of the mounting portion and is flush with the end face of the display panel.

[0015] In another embodiment of this application, the lower end of the display panel is provided with a front contact surface and two side contact surfaces, the front contact surface and the two side contact surfaces surrounding the circumference of the mounting portion; the front contact surface and the side contact surfaces are both inclined along their width direction. Correspondingly, the upper surface of the dustproof panel is adapted to the front contact surface and the side contact surface.

[0016] In another embodiment of this application, a protrusion is further provided on the side contact surface, the protrusion is fitted to the mounting portion, and the thickness of the protrusion is less than the width of the side contact surface.

[0017] In another embodiment of this application, the front contact surface is V-shaped, and the mounting portion includes two mounting blocks symmetrically arranged along the centerline of the display panel.

[0018] In another embodiment of this application, the dustproof panel includes: A dust cover, wherein the connecting part is located on the inner side of the dust cover; A dustproof mesh frame is located inside the dustproof cover; The frame positioning structure includes multiple positioning buckles located inside the dust cover. The multiple positioning buckles are distributed at intervals along the trajectory of the dust cover and engage with the dust cover to fix the dust cover inside the dust cover. The skeleton auxiliary positioning structure includes an auxiliary positioning protrusion located at the upper end of the dustproof mesh frame and an auxiliary positioning hole opened on the connecting part, wherein the auxiliary positioning protrusion and the auxiliary positioning hole are engaged in a one-to-one correspondence.

[0019] A chassis is also provided, characterized in that it includes the aforementioned easy-to-maintain dustproof panel structure.

[0020] The beneficial effects of the chassis provided by this invention are as follows: Compared with the prior art, the chassis of this invention adopts the aforementioned easy-to-maintain dustproof panel structure, possessing all its beneficial effects and solving the problem of inconvenient maintenance of traditional integrated panel chassis. In scenarios with multiple machines connected in parallel and narrow gaps between adjacent chassis, the dustproof panel or display panel can be disassembled individually for maintenance, significantly reducing operational difficulty, improving maintenance efficiency, and avoiding the risk of equipment collision damage due to space constraints. The precise assembly positioning structure and robust connection design improve the overall structural reliability of the chassis, enabling it to resist external forces and vibrations during transportation, installation, and use, ensuring operational stability.

[0024] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0025] Please see Figures 1 to 21The present invention will now describe the easy-to-maintain dustproof panel structure and chassis provided. The easy-to-maintain dustproof panel structure includes a separate display panel 200 and a dustproof panel 300. The display panel 200 is detachably connected to the chassis body 100, and a mounting portion 207 is provided at the lower end of the display panel 200. The dustproof panel 300 is detachably connected to the chassis body 100, and a connecting portion 305 is provided on the inner side of the dustproof panel 300. The connecting portion 305 connects to the mounting portion 207, so that the upper end of the dustproof panel 300 covers the outer side of the mounting portion 207. The dustproof panel 300 and the display panel 200 cooperate to seal the front port of the chassis body 100.

[0026] The dustproof panel structure provided by this invention can be installed on both vertical and horizontal chassis. In the vertical chassis, the upper end of the display panel 200 is snapped into the upper edge of the chassis body 100, and the lower end of the display panel 200 is provided with a mounting part 207; the upper end of the dustproof panel 300 engages with the mounting part 207, and the lower end of the dustproof panel 300 is detachably connected to the lower edge of the chassis body 100. For the horizontal chassis, simply rotate the vertical chassis 90° counterclockwise or clockwise and lay it down; this does not affect the connection between the easy-to-maintain dustproof panel structure and the chassis body 100.

[0027] The following descriptions all use a vertical chassis as an example.

[0028] The computer chassis requires regular maintenance during operation. Traditional chassis typically have a single front panel, with the monitor (201) mounted on the upper half and a ventilation dust filter on the lower half. The dust filter requires more frequent maintenance than the monitor itself. Each maintenance requires removing the entire panel, which is not only cumbersome but also increases the risk of damage to the monitor.

[0029] This application proposes to divide the easy-to-maintain dustproof panel structure into two parts: one part is a display panel 200, in which a display 201 is installed; the other part is a dustproof panel 300 for dust protection.

[0030] The front opening of the chassis body 100 can be divided into two connected areas, with the first area located above the second area. The first area is used to install the display panel 200, and the second area is used to install the dustproof panel 300. The front opening of the chassis body 100 is provided with mounting base plates, namely the display base plate and the dustproof base plate. The display base plate 203 provides a mounting base for the display panel 200, and the dustproof base plate 302 provides a mounting base for the dustproof panel 300.

[0031] The upper end of the dustproof panel 300 covers the outer side of the mounting part 207, and the overlapping arrangement blocks the connection gap between the two; while the connecting part 305 on the inner side of the dustproof panel 300 is engaged with the mounting part 207 to fix the upper end; the lower end of the dustproof panel 300 and the lower end of the chassis body 100 can be detached and fixed by means of snap-fit, bolt fixation or other methods.

[0032] The dustproof panel structure provided by this invention is easy to maintain. Compared with the prior art, when maintenance is required, only the dustproof panel 300 needs to be removed. Removal is convenient and avoids the problem of limited space in adjacent chassis restricting the disassembly of the entire panel, thus improving maintenance efficiency. The mounting part 207, the connecting part 305, and the upper end of the dustproof panel 300 cooperate to ensure precise assembly and connection between the dustproof panel 300 and the display panel 200, reducing the gap at the joint and improving the sealing effect at the joint.

[0033] For example, the upper end of the display panel 200 is first snapped into the chassis body 100. After the snapping is completed, the display panel 200 is attached to the front end of the chassis body 100. The lower end of the display panel 200 is attached to the folded edge structure 101 of the chassis body 100 and fixed by means of bolts or other structures.

[0034] The chassis body 100 has symmetrical folded edge structures 101 on both sides in the width direction. The folded edge structure 101 in the first area is used to fix the display base plate 203. The display base plate 203 is installed on the folded edge structure 101 of the chassis body 100 by bolts. The upper end of the display base plate 203 has a relief groove, which cooperates with the upper edge of the chassis body 100 to form a relief hole 104. The upper end of the display panel 200 is provided with an upper buckle 204, which is used to snap into the relief hole 104.

[0035] The folded edge structure 101 in the second area is used to fix the dustproof base plate 302. If the dustproof base plate 302 has multiple fixing holes, the fixing holes are fixedly connected to the folded edge structure 101 at the front end of the chassis body 100 by bolts.

[0036] During installation, first fix the display panel 200, then fix the dustproof panel 300. When removing, do the opposite: first remove the dustproof panel 300, then remove the display panel 200.

[0037] In some possible embodiments, please refer to Figure 4 , Figure 8 , Figure 11 , Figure 18The easily maintained dustproof panel structure also includes a lower locking structure and an upper locking structure. The lower locking structure includes a snap-fit ​​hole 103 at the lower end of the chassis body 100 and a snap-fit ​​buckle 306 at the lower end of the dustproof panel 300. The snap-fit ​​buckle 306 snaps into the snap-fit ​​hole 103 in the front-to-back direction to limit the displacement of the dustproof panel 300 in the left-to-right and up-to-down directions. The upper locking structure includes a positioning protrusion 208 on the lower end surface of the mounting part 207 and a limiting hole 309 on the connecting part 305. The positioning protrusion 208 protrudes downward and snaps into the limiting hole 309 one-to-one to limit the displacement of the dustproof panel 300 in the front-to-back direction. Optionally, the cross-section of the positioning protrusion 208 is trapezoidal.

[0038] A snap-fit ​​groove is provided at the lower end of the dustproof base plate 302. After the dustproof base plate 302 is fixed on the chassis body 100, the snap-fit ​​groove of the dustproof base plate 302 and the bottom plate or folded edge structure 101 of the chassis body 100 cooperate to form a snap-fit ​​hole 103.

[0039] The upper end of the dustproof panel 300 is fixed by the limiting hole 309 on the connecting part 305 cooperating with the positioning protrusion 208 on the mounting part 207, so that the dustproof panel 300 is fixed.

[0040] During installation, the display panel 200 is installed first, followed by the dustproof panel 300. When installing the dustproof panel 300, first insert the lower snap-fit ​​306 of the dustproof panel 300 into the snap-fit ​​hole 103 to position the lower end of the dustproof panel 300. Then, under pressure, move the upper end of the dustproof panel 300 towards the chassis side. Due to the avoidance design of the positioning protrusion 208 on the lower surface of the mounting part 207, the connecting part 305 located on the inner side of the upper end of the dustproof panel 300 can smoothly pass through the positioning protrusion 208, allowing the positioning protrusion 208 to insert into the limiting hole 309 of the connecting part 305. After the pressure on the upper end of the dustproof panel 300 is released, the positioning protrusion 208 at its upper end is fully engaged in the limiting hole 309 and cannot be freely dislodged.

[0041] After the snap fastener 306 is engaged, under stress, the dustproof panel 300 can rotate around the snap fastener 306 within a certain angle. The rotation angle of the dustproof panel 300 causes the limiting hole 309 to engage with the positioning protrusion 208.

[0042] To facilitate the installation of the dustproof panel 300, the positioning protrusion 208 includes a snap-fit ​​portion and a guide portion connected in sequence. The snap-fit ​​portion is connected to the lower end face of the mounting portion 207 and is adapted to the limiting hole 309. The guide portion is connected to the lower end of the snap-fit ​​portion, and a guide surface 2081 is provided on the inner side of the guide portion. The guide surface 2081 is inclined from top to bottom and outward, so that the limiting hole 309 can smoothly pass through the guide portion and engage with the snap-fit ​​portion during the process of the dustproof panel 300 flipping and snapping around the snap-fit ​​buckle 306. The positioning protrusion 208 forms an avoidance design at the guide portion with the help of the guide surface 2081.

[0043] The inner edge of the limiting hole 309 is fitted onto the guide surface 2081. As the dustproof panel 300 is pressed and rotated, the limiting hole 309 moves inward along with the guide surface 2081 until it passes through the corner where the guide part and the snap-fit ​​part connect. The inner wall of the limiting hole 309 forms an interference fit with the corner. After passing through the corner, the limiting hole 309 engages with the snap-fit ​​part.

[0044] After installation, the positioning protrusion 208 and the limiting hole 309 cooperate to limit the upper end of the dustproof panel 300 in the front-back and left-right directions. When the limiting hole 309 is fully fitted onto the outside of the positioning protrusion 208, the limiting hole 309 fits against the snap-fit ​​part, thereby ensuring a reliable connection between the dustproof panel 300 and the display panel 200.

[0045] When removing the dustproof panel 300, first apply slight downward force to the upper end of the dustproof panel 300 until the connecting part 305 of the dustproof panel 300 comes off the positioning protrusion 208, and then release the snap fastener 306 at the lower end of the dustproof panel 300 from the snap hole 103.

[0046] Optionally, a recessed handle groove 301 is provided at the lower end of the dustproof panel 300. The handle groove 301 facilitates the application of force by the operator to move the machine box. Figure 2 and Figure 3 As shown.

[0047] In some possible embodiments, please refer to Figure 11 , Figure 17 and Figure 18 The easy-to-maintain dustproof panel structure also includes an auxiliary locking structure, which includes multiple positioning posts 314 located inside the dustproof panel 300 and multiple positioning holes 308 opened on the chassis body 100. The ends of the positioning posts 314 extend into the positioning holes 308 and engage with the positioning holes 308.

[0048] The opening slot 102 on the folded edge structure 101 at the front end of the chassis body 100 corresponds one-to-one with the positioning hole 308 on the dustproof base plate 302. The length direction of the opening slot 102 is consistent with the width direction of the chassis body 100. The opening slot 102 is used to make way for the positioning hole 308 to avoid affecting the insertion and removal of the positioning post 314.

[0049] The positioning post 314 is fixedly installed on the inner side of the dustproof panel 300. The positioning post 314 extends backward and its length is greater than the cavity depth between the dustproof panel 300 and the dustproof base plate 302, so that the end of the positioning post 314 can extend into the positioning hole 308.

[0050] When installing the dustproof panel 300, first, snap the lower end of the dustproof panel 300 into the snap hole 103. Then, rotate the upper end of the dustproof panel 300 inward around the lower end snap 306 until the snap is complete. Before rotation, there is an angle between the dustproof panel 300 and the dustproof base plate 302. The positioning post 314 abuts against the opening of the positioning hole 308, and the axial direction of the positioning post 314 and the axial direction of the positioning hole 308 form an angle. During the pressing of the dustproof panel 300, the dustproof panel 300 will rotate at an angle. During the rotation, the positioning post 314 and the positioning hole 308 are inserted into the positioning hole 308 through an interference fit, and the axial direction of the positioning post 314 and the positioning hole 308 coincides.

[0051] After installation, the positioning protrusion 208 and the limiting hole 309 cooperate to limit the upper end of the dustproof panel 300 in the front-back and left-right directions. The positioning post 314 cooperates with the positioning hole 308 to limit the dustproof panel 300 in the up-down and left-right directions. During removal, the operator needs to forcefully pull the upper end of the dustproof panel 300, while the positioning post 314 rotates with the dustproof panel 300 until the positioning post 314 disengages from the positioning hole 308.

[0052] The auxiliary locking structure, in conjunction with the upper and lower locking structures, allows the dustproof panel 300 to be fixed to the chassis body 100 simply by snapping on, without the need for screws. This ensures stable installation while also facilitating easy assembly and disassembly.

[0053] Optionally, the thickness of the mounting part 207 is less than the thickness of the display panel 200. When the installation is complete, the upper end of the dustproof panel 300 covers the outside of the mounting part 207 and is flush with the end face of the display panel 200.

[0054] In some possible embodiments, please refer to Figure 7 , Figure 8 , Figure 10 and Figure 14The lower end of the display panel 200 is provided with a front contact surface 206 and two side contact surfaces 210. The front contact surface 206 and the two side contact surfaces 210 surround the circumference of the mounting portion 207, and the front contact surface 206 and the side contact surfaces 210 cooperate with the mounting portion 207 to form a mounting area; both the front contact surface 206 and the side contact surfaces 210 are inclined along their width direction. Correspondingly, the upper end surface of the dustproof panel 300 is adapted to the front contact surface 206 and the side contact surfaces 210.

[0055] For example, the front contact surface 206 and the side contact surface 210 gradually tilt towards one side of the dustproof panel 300 from the outside to the inside.

[0056] The mounting area is a U-shaped region surrounding the mounting portion 207, located on the front and left and right sides of the mounting portion 207. The lower end of the display panel 200 has a front contact surface 206 on the front side of the display panel 200 and side contact surfaces 210 on both sides of the display panel 200, with the front contact surface 206 and both side contact surfaces 210 facing the dustproof panel 300. After installation, the front contact surface 206 and the two side contact surfaces 210 either fit against the upper end face of the dustproof panel 300 or have a gap between them.

[0057] To reduce the depth of the gap, both the front contact surface 206 and the side contact surface 210 are inclined surfaces, gradually sloping upwards from the inner edge to the outer edge along the width direction. The inclination angle is between 30° and 60°.

[0058] The inclined design of the front contact surface 206 and the side contact surface 210 visually reduces the depth of the gap and improves the aesthetics of the product.

[0059] The complementary fit design of the inclined surface significantly reduces the depth of the connection gap. Compared with the flat connection, it can effectively prevent dust, moisture and other impurities from entering the chassis body 100 through the gap, further improving the sealing and protection performance.

[0060] In some possible embodiments, please refer to Figures 13 to 15 The side contact surface 210 is also provided with a protrusion 212, which is attached to the mounting part 207. The thickness of the protrusion 212 is less than the width of the side contact surface 210, and the length of the protrusion 212 is less than the length of the side contact surface 210. The protrusion 212 is used to attach to the left and right side panels of the dustproof panel 300 respectively.

[0061] The width of the inner side of the dustproof panel 300 is greater than the overall width of the mounting portion 207. Protrusions 212 are provided on both sides of the mounting portion 207 to increase the width of a portion of the mounting portion 207. During installation, the protrusions 212 on both sides of the mounting portion 207 are used to fit against the inner side of the dustproof panel 300, abutting against the dustproof panel 300 to prevent the dustproof panel 300 from wobbling left and right.

[0062] The protrusion 212 effectively reduces the contact area between the display panel 200 and the dustproof panel 300, thereby reducing the friction of the dustproof panel 300 during installation and removal. By maintaining the installation stability of the dustproof panel 300 through a small contact area, the precision required for the dustproof panel 300 and the mounting part 207 can be reduced.

[0063] In addition, the upper end of the protrusion 212 extends to the side contact surface 210, and the protrusion 212 can also reduce the visual width of the gap by changing the depth of the gap.

[0064] The front end of the protrusion 212 is inclined or curved to achieve a smooth transition and allow it to fit smoothly with the dustproof panel 300.

[0065] In some possible embodiments, please refer to Figures 13 to 14 The front contact surface 206 is V-shaped, and the mounting part 207 includes two mounting blocks symmetrically arranged along the center line of the display panel 200.

[0066] The V-shaped front contact surface 206 consists of two inclined surfaces, forming a fitting structure with the upper end face of the dustproof panel 300. The display panel 200 and the dustproof panel 300 form a V-shaped connection track at the front, and by changing the extension direction of the track, the visual width of the gap is reduced.

[0067] Two symmetrically arranged mounting blocks and positioning protrusions 208 ensure a symmetrical distribution of the snap-fit ​​structure. When the connecting part 305 and the mounting part 207 snap together, the force is more evenly distributed, avoiding loose connections or panel misalignment caused by excessive force on one side. During assembly, the dustproof panel 300 is aligned with the mounting blocks under the bidirectional guidance of the V-shaped front contact surface 206. The limiting holes 309 of the connecting part 305 snap into each mounting block in a one-to-one correspondence with the positioning protrusions 208, forming a stable symmetrical snap-fit ​​structure.

[0068] In some possible embodiments, please refer to Figure 13 , Figure 14 and Figure 16 The display panel 200 also includes a light guide strip 205, the edge of which is flush with the front contact surface 206. A light-diffusing structure is provided on the inner side of the light guide strip 205, which includes multiple staggered prismatic reflective surfaces.

[0069] The design of the light guide strip 205 with its edge flush with the front contact surface 206 ensures that it does not protrude from the front contact surface 206, avoiding interference with the assembly of the dustproof panel 300 and ensuring the flatness of the display panel 200's appearance. Multiple staggered prismatic reflective surfaces on the inner side of the light guide strip 205 can reflect and refract incident light multiple times, breaking the directional propagation path of light and allowing light to be evenly scattered to the display area, solving the problems of uneven light distribution and bright spots or dark areas in traditional light guide structures. The integrated design of the light guide strip 205 and the display panel 200 does not affect the panel's separate assembly and disassembly logic, optimizing display functions while maintaining maintenance flexibility.

[0070] A button 202 is also provided above the light guide strip 205.

[0071] The lower part of the display base plate 203 is provided with bolt holes, and the lower end of the mounting part 207 is provided with at least two outwardly protruding sheet-like connecting structures 211. The sheet-like connecting structures 211 are attached to the display base plate 203, and through holes corresponding to the bolt holes at the lower part of the display base plate 203 are provided on the sheet-like connecting structures 211.

[0072] During installation, the display base plate 203 is first installed on the chassis body 100. Then, the upper end of the display panel 200 is snapped into the clearance hole 104, and the lower end of the sheet-like connecting structure 211 is attached to the display base plate 203. Only bolts are needed to lock the sheet-like connecting structure 211 onto the display base plate 203.

[0073] During inspection and maintenance, only the dustproof panel 300 needs to be removed; the display panel 200 does not need to be removed. When it is necessary to remove the display panel 200, first remove the dustproof panel 300, then remove the bolts on the sheet-like connecting structure 211, and finally remove the upper clip 204 of the display panel 200. At this point, the monitor 201, circuit board, and other structures can be inspected and repaired.

[0074] The display 201 and buttons 202 are embedded on the front surface of the display panel 200. Specifically, the display panel 200 has mounting holes for the display, buttons, and light guide strips. Due to the manufacturing process, several positioning pins 209 exist between the button mounting holes and the light guide strip mounting holes on the display panel 200. In traditional processes, these positioning pins 209 need to be melted away. In this application, a positioning ring 213 is provided on the button 202 structure to engage with the positioning pins 209. This reduces the need for melting the positioning pins 209 while further restricting the position of the button 202, improving the installation accuracy of the button 202.

[0075] The display panel 200 is also provided with circuit board mounting holes 214 extending in the front-to-back direction. Bolts pass through the circuit board and are connected in the circuit board mounting holes 214 to fix the circuit board in the display panel 200.

[0076] Specifically, please refer to Figure 3 , Figure 10 , Figures 18 to 21 The dustproof panel 300 includes a dustproof cover 304, a dustproof mesh frame 307, a frame positioning structure, and a frame auxiliary positioning structure. The connecting part 305 is located inside the dustproof cover 304; the dustproof mesh frame 307 is located inside the dustproof cover 304.

[0077] The dust cover 304 is a cover structure made of plastic or metal. The dust cover 304 includes a front mesh, side frames on both sides, and a bottom frame, with the mesh and side frames integrally formed. The connecting part 305 is a plate-like structure located at the front of the inner side of the dust cover 304, and is integrally formed with the mesh and the side frames. The connecting part 305, the side frames, and the bottom frame enclose a rectangular mounting cavity.

[0078] The dustproof mesh frame 307 is equipped with a filter screen or a filter sponge on the front side of the dustproof mesh frame to achieve the dustproof effect. The dustproof mesh frame 307 has a rectangular frame structure and is located close to the inner side of the surrounding side wall of the dustproof cover 304, which can also improve the strength of the dustproof cover 304.

[0079] Correspondingly, the dustproof mesh frame 307 has an inwardly extending handle support 312 at its lower end. The handle support 312 is located inside the plate of the handle groove 301 to increase the structural strength of this part. Figure 19 As shown.

[0080] The frame positioning structure includes multiple positioning buckles 311 located inside the dust cover 304. The multiple positioning buckles 311 are distributed at intervals along the trajectory of the dust cover 307 and engage with the dust cover 307 to fix the dust cover 307 inside the dust cover 304.

[0081] The positioning buckle 311 extends inward along the thickness direction and fits against the outer side of the dustproof mesh frame 307, fixing the dustproof mesh frame 307 inside the dustproof cover 304. The positioning buckle 311 is connected and fixed to the side frame and the bottom frame by reinforcing ribs.

[0082] Please see Figures 18 to 21 The skeleton auxiliary positioning structure includes an auxiliary positioning protrusion 313 located on the upper end of the dustproof mesh frame 307 and an auxiliary positioning hole 310 opened on the connecting part 305. The auxiliary positioning protrusion 313 and the auxiliary positioning hole 310 are engaged in a one-to-one correspondence.

[0083] When assembling the dustproof mesh frame 307, dust cover 304, and connecting part 305, the auxiliary positioning protrusion 313 is inserted into the auxiliary positioning hole 310 to quickly achieve the positioning of the dustproof mesh frame 307 and connecting part 305.

[0084] This positioning and fitting method can limit the displacement of the dustproof mesh frame 307 in the horizontal and vertical directions, ensure the accurate relative position of the dustproof mesh frame 307 and the connecting part 305, and thus ensure the fitting accuracy of the dustproof mesh frame 307 with the dustproof cover 304 and the dustproof base plate 302.

[0085] Meanwhile, the auxiliary positioning structure works in synergy with the positioning buckle 311 of the dust cover 304 and the snap-fit ​​structure of the dust cover base plate 302 to make the assembly of each component of the entire dust cover panel 300 more precise and orderly.

[0086] Please see Figure 1 The company also provides a chassis that includes the aforementioned easy-to-maintain dustproof panel structure.

[0087] The chassis provided by this invention, compared with the prior art, adopts the aforementioned easy-to-maintain dustproof panel structure, possessing all its beneficial effects and solving the problem of inconvenient maintenance of traditional integrated panel chassis. In scenarios with multiple machines connected in parallel and narrow gaps between adjacent chassis, the dustproof panel 300 or display panel 200 can be disassembled individually for maintenance, significantly reducing operational difficulty, improving maintenance efficiency, and avoiding the risk of equipment collision damage due to space constraints. The precise assembly positioning structure and robust connection design enhance the overall structural reliability of the chassis, enabling it to resist external forces and vibrations during transportation, installation, and use, ensuring operational stability.

[0088] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
