[0001] This utility model relates to the field of waveguide plate technology, and in particular to a combined ventilated waveguide plate that can improve shielding performance. Background Technology

[0002] As electronic devices evolve towards higher frequencies and greater integration, electromagnetic shielding performance has become a critical indicator. Ventilation waveguides, as core components for heat dissipation and electromagnetic shielding in electronic devices, directly impact equipment reliability. Traditional ventilation waveguides often employ single metal aperture arrays or honeycomb structures, which, while providing basic shielding effectiveness, suffer from insufficient high-frequency shielding, low structural strength, and limited ventilation efficiency.

[0003] Furthermore, most existing ventilation waveguides are integrally molded, which makes maintenance difficult and cannot be adapted to different shielding scenarios. Utility Model Content

[0004] The main purpose of this invention is to provide a combined ventilated waveguide plate that can improve shielding performance, so that the shielding performance of the waveguide plate can be quickly and stably adjusted according to user needs.

[0005] To achieve the above objectives, this utility model proposes a combined ventilated waveguide plate that can improve shielding performance, including a waveguide plate body. The waveguide plate body includes a mounting frame and a filter plate disposed within the mounting frame. The filter plate has a plurality of first waveguide holes arrayed along the extension direction of the mounting frame.

[0006] A mating assembly is connected to one side of the waveguide plate body. The mating assembly has multiple mating plates protruding from the multiple first waveguide holes and passing through the first waveguide holes. Each mating plate has a second waveguide hole. The first waveguide hole and the second waveguide hole are coaxially arranged.

[0007] In one embodiment of this application, a guide structure and a lifting structure are provided between the mating component and the mounting bracket. The guide structure is connected to one side of the mounting bracket, and the lifting structure is connected to the other side of the mounting bracket.

[0008] In one embodiment of this application, the guide structure includes a limiting block disposed on the mounting bracket or the mating component and a limiting groove disposed on the mating component or the mounting bracket, wherein the limiting block is slidably connected to the limiting groove.

[0009] In one embodiment of this application, the guide structure is provided in at least two sets, and the two sets of guide structures are symmetrically arranged.

[0010] In one embodiment of this application, the lifting structure includes a drive gear rotatably connected to the inner wall of the mounting frame or the mating component, and a mating block disposed on the inner wall of the mating component or the mounting frame. One end of the mating block is connected to the guide structure, and the other end is provided with a lifting rack relative to the drive gear.

[0011] The mating block and mating assembly are provided with a clearance cavity relative to the drive gear.

[0012] In one embodiment of this application, the drive gear is rotatably connected to the mounting bracket, the mating assembly has a clearance groove on the movement trajectory of the drive gear's central shaft, and the drive gear is connected to a knob that passes through the clearance groove.

[0013] In one embodiment of this application, the drive gear is connected to a rotating shaft passing through the mounting bracket on the side opposite to the knob, and a drive gear is connected to each end of the rotating shaft. Two mating blocks are provided on both sides of the mating assembly opposite to the two drive gears.

[0014] By adopting the above technical solution, this utility model has the following advantages:

[0015] This utility model's technical solution employs a modular structural design, enabling the entire ventilation waveguide plate to quickly and stably adjust its actual shielding performance according to the user's specific shielding requirements. To achieve this function, the waveguide plate body is structurally divided into a mounting frame and a filter plate housed within the mounting frame. The filter plate has multiple first waveguide holes along the height direction of the mounting frame, resulting in a honeycomb structure that provides the filter plate itself with superior shielding performance.

[0016] Because the shielding effect of the waveguide plate is directly related to the diameter and depth of the waveguide aperture, the smaller the aperture, the better the shielding effect, and the deeper the aperture, the better the shielding effect. In order to adjust the shielding performance, a mating component is connected to one side of the waveguide plate. Multiple mating plates are inserted through the mating component. The mating plate itself has a second waveguide aperture, and the mating plate is inserted and slidably connected to the first waveguide aperture. The first waveguide aperture and the second waveguide aperture together form a waveguide through-hole. After the waveguide plate is fixed, the depth of the waveguide through-hole and the relative position of the large and small apertures can be quickly and stably changed by adjusting the mating component, so as to quickly achieve combined adjustment of shielding performance.

[0022] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0024] The following is in conjunction with the appendix Figure 1-2 The present invention will be further described below.

[0025] The present invention proposes a combined ventilated waveguide plate that can improve shielding performance, including a waveguide plate body 1. The waveguide plate body 1 includes a mounting frame 11 and a filter plate 12 disposed in the mounting frame 11. The filter plate 12 has a plurality of first waveguide holes 13 arrayed along the extension direction of the mounting frame 11.

[0026] A mating component 2 is connected to one side of the waveguide plate body 1. The mating component 2 has multiple mating plates 3 protruding from the multiple first waveguide holes 13 and passing through the first waveguide holes 13. Each mating plate 3 has a second waveguide hole 31. The first waveguide hole 13 and the second waveguide hole 31 are coaxially arranged.

[0027] This utility model's technical solution employs a modular structural design, enabling the entire ventilation waveguide plate to quickly and stably adjust its actual shielding performance according to the user's specific shielding requirements. To achieve this function, the waveguide plate body 1 is structurally divided into a mounting frame 11 and a filter plate 12 housed within the mounting frame 11. The filter plate 12 has multiple first waveguide holes 13 along the height direction of the mounting frame 11, giving the entire filter plate 12 a honeycomb structure and thus providing it with superior shielding performance.

[0028] Because the shielding effect of the waveguide plate body 1 is directly related to the diameter and depth of the waveguide hole, the smaller the diameter, the better the shielding effect, and the deeper the depth, the better the shielding effect. In order to adjust the shielding performance, a mating component 2 is connected to one side of the waveguide plate body 1. Multiple mating plates 3 are inserted through the mating component 2. The mating plate 3 itself has a second waveguide hole 31, and the mating plate 3 is inserted and slidably connected in the first waveguide hole 13. The first waveguide hole 13 and the second waveguide hole 31 together form a waveguide through hole. After the waveguide plate body 1 is fixed, the depth of the waveguide through hole and the relative position of the large and small diameter holes can be quickly and stably changed by adjusting the mating component 2, so as to quickly achieve combined adjustment of shielding performance.

[0029] In one embodiment of this application, a guide structure 4 and a lifting structure 5 are provided between the mating component 2 and the mounting bracket 11. The guide structure 4 is connected to one side of the mounting bracket 11, and the lifting structure 5 is connected to the other side of the mounting bracket 11. Both the guide structure 4 and the lifting structure 5 can limit one side of the mounting bracket 11, which can ensure the stability of the movement between the filter plate 12 and the mating plate 3 when adjusting the shielding performance, making the shielding performance adjustment process smoother.

[0030] In one embodiment of this application, the guide structure 4 includes a limiting block 41 disposed on the mounting frame 11 or the mating component 2 and a limiting groove 42 disposed on the mating component 2 or the mounting frame 11. The limiting block 41 is slidably connected to the limiting groove 42. The limiting block 41 and the limiting groove 42 cooperate with each other to limit one corner of the mounting frame 11, ensuring stable movement between the mounting frame 11 and the mating component 2. Furthermore, the limiting block 41 passes through the limiting groove 42 and can be used to limit both of them, preventing the mounting frame 11 from coming off the mating component 2.

[0031] In one embodiment of this application, the guide structure 4 is provided in at least two sets, and the two sets of guide structures 4 are symmetrically arranged, which can make the movement between the waveguide plate body 1 and the mating component 2 more stable and the lifting state more uniform.

[0032] In one embodiment of this application, the lifting structure 5 includes a drive gear 51 rotatably connected to the inner wall of the mounting frame 11 or the mating component 2, and a mating block 53 disposed on the inner wall of the mating component 2 or the mounting frame 11. One end of the mating block 53 is connected to the guide structure 4, and the other end is provided with a lifting rack relative to the drive gear 51.

[0033] The mating block 53 and the mating component 2 are provided with a relief cavity relative to the drive gear 51. The user can directly contact and adjust the drive gear 51 through the relief cavity, which can ensure the accuracy of adjustment.

[0034] When the drive gear 51 rotates and connects to the inner wall of the mating component 2, the mating block 53 is mounted on the mounting bracket 11. The central shaft of the drive gear 51 passes through the mating component 2, and a knob can be set on it, which allows the user to directly operate the lifting and lowering of both. The two sides of the mating block 53 are respectively connected to the guide structure 4 and the lifting structure 5, which can ensure more stable lifting and lowering. By setting a lifting rack on the mating block 53, the user can quickly adjust the shielding performance through the knob.

[0035] In one embodiment of this application, the drive gear 51 is rotatably connected to the mounting bracket 11, and the mating component 2 is provided with a relief groove 21 relative to the movement trajectory of the drive gear 51's central axis. The drive gear 51 is connected to a knob that passes through the relief groove 21.

[0036] When the drive gear 51 is connected to the mounting bracket 11, a clearance groove 21 needs to be provided on the mating assembly 2 so that the waveguide plate body 1 can move freely. The knob for operating the drive gear 51 is connected to the drive gear 51, and the central shaft of the knob passes through the clearance groove 21.

[0037] In one embodiment of this application, a drive gear 51 is connected to a rotating shaft 52 passing through the mounting bracket 11 on the side opposite to the knob. Both ends of the rotating shaft 52 are connected to a drive gear 51. Two mating blocks 53 are provided on both sides of the mating assembly 2 opposite to the two drive gears 51.

[0038] To further improve the stability of shielding performance adjustment, the drive gear 51 is equipped with a rotating shaft 52 that runs across the entire side of the mounting bracket 11. Both ends of the rotating shaft 52 are connected to the drive gear 51, and both sides of the mounting bracket 11 are equipped with mating blocks 53 with lifting racks, so that the lifting structure 5 can be symmetrically arranged except for the knob. In particular, the knob can also be symmetrically arranged. Through the above structure, the shielding performance of the ventilation waveguide plate itself can be freely adjusted, which can effectively improve the user experience.
