Detailed Implementation

[0033] The present invention will be further described in detail below with reference to the accompanying drawings.

[0034] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive element, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.

[0035] This embodiment relates to an airflow regulating device, see reference Figures 1-3 It includes: the first plate 100, the second plate 200, the sliding mechanism 300, and the adjusting mechanism 400.

[0036] The system comprises two sections: a first plate 100 with multiple first mesh openings 110, and a second plate 200 with two slidably mounted on either side of the first plate 100, each adjustable independently. The second plate 200 also has multiple second mesh openings 210, corresponding to the first mesh openings 110. When the second mesh openings 210 and 110 are completely overlapped, the opening ratio is maximized, resulting in maximum airflow. When the second mesh openings 210 and 110 are misaligned, the overlap area is smaller, and the airflow decreases. A sliding mechanism 300 is connected at both ends between the first plate 100 and the second plate 200, ensuring that the second plate 200 maintains axial linear motion during sliding. Two adjusting mechanisms 400 are provided, each positioned between the first plate 100 and the second plate 200, to control the sliding of the second plate 200 relative to the first plate 100. Specifically, the two adjusting mechanisms 400 can adjust different overlap areas of the two mesh openings to achieve airflow regulation.

[0037] Reference Figure 2 , Figures 7-11 When the adjusting mechanism 400 rotates in one direction at a set angle, it causes the second plate 200 to slide relative to the first plate 100, thereby adjusting the overlapping area of ​​the first mesh 110 and the second mesh 210 to regulate the airflow output. The two adjusting mechanisms 400 can rotate independently at different angles, thus controlling the second plates 200 on both sides to slide axially relative to the first plate 100 at different distances. This allows for adjustment of the overlapping areas of the first mesh 110 and the second mesh 210, thereby regulating different airflow outputs and achieving airflow adjustment at different levels. Therefore, this airflow regulating device can balance the airflow speed near the air outlet and in remote locations by adjusting the different overlapping areas of the first mesh 110 and the second mesh 210 on both sides, based on the heat dissipation needs of different parts of the cooling unit. This avoids excessive or insufficient local airflow, achieving uniform heat dissipation, dynamically distributing airflow, optimizing heat dissipation efficiency, improving heat dissipation effect, and reducing energy loss.

[0038] Furthermore, a bend (not shown) is provided on the side of the second plate 200 away from the adjustment mechanism 400. When the second plate 200 is slidably adjusted, the bend is used to avoid the support member in the middle of the first plate 100, forming a misaligned fit to make the structure compact and improve the utilization of space, while not affecting the adjustment of air volume.

[0039] In this embodiment, refer to Figures 3-4 The adjusting mechanism 400 includes a rack 410, a gear 420, and an adjusting assembly 430. The rack 410 is fixed to the second plate 200. The gear 420 meshes with the rack 410 and is connected to the adjusting assembly 430. The rack 410 serves as the linear motion track for the gear 420, converting the rotational motion of the gear 420 into linear sliding of the second plate 200, resulting in high transmission accuracy. One end of the adjusting assembly 430 is located on the side of the first plate 100 near the rack 410, and the other end is connected to the gear 420. The adjusting assembly 430 controls and drives the gear 420 to rotate. The rotation of the gear 420 drives the rack 410 to move linearly, thereby causing the second plate 200 to slide. The adjustment group 430 can achieve precise control of the rotation angle of the gear 420, thereby accurately controlling the sliding distance of the second plate 200. The forward and reverse rotation of the gear 420 can drive the rack 410 to slide in both directions, so that the second plate 200 can move back and forth on both sides of the first plate 100, thereby increasing or decreasing the overlapping area of ​​the mesh and meeting the bidirectional adjustment needs of increasing or decreasing the air volume.

[0040] Furthermore, the adjustment assembly 430 includes a mounting plate 431, an adjustment handle 432, and a rotating shaft 433. One end of the mounting plate 431 is fixed to the first plate 100, while the other end is a free end extending to the outside of the gear 420. The adjustment handle 432 is rotatably mounted on the side of the mounting plate 431 facing away from the gear 420 and is used to control the rotation of the gear 420. Specifically, the adjustment handle 432 is mounted on the outside of the mounting plate 431 for easy manual adjustment by the user. One end of the drive shaft is connected to the adjustment handle 432, and the other end is connected to the gear 420. Rotating the handle directly drives the rotating shaft 433 and the gear 420 to rotate, ensuring efficient force transmission and transmission efficiency.

[0041] In this embodiment, refer to Figures 4-5 The adjustment handle 432 includes a first handle plate 4321, a second handle plate 4322, a positioning member 4323, and an elastic member 4324. The first handle plate 4321 is rotatably mounted on the mounting plate 431 to drive the gear 420 to rotate via the rotating shaft 433, serving as the power output hub of the adjustment mechanism 400. The second handle plate 4322 is rotatably mounted on the side of the first handle plate 4321 facing away from the mounting plate 431, with one end bent and extended away from the first handle plate 4321 to form a pressing handle for easy pressing by the user. One end of the positioning member 4323 is located on the side of the second handle plate 4322 facing the first handle plate 4321, and the other end is movably inserted through the first handle plate 4321. The mounting plate 431 has multiple through holes 4311 for the positioning member 4323 to be inserted into the through holes 4311 for adjustment and positioning. When the second handle plate 4322 is pressed repeatedly, the positioning member 4323 can move and extend on the first handle plate 4321, and reciprocately insert into the through hole 4311 for positioning, restricting the rotation of the first handle plate 4321 and ensuring the stability of the airflow output. Moreover, multiple through holes 4311 correspond to different angles, allowing the positioning member 4323 to match different airflow levels. The elastic member 4324 is located between the first handle plate 4321 and the side of the second handle plate 4322 away from the positioning member 4323, so that when the second handle plate 4322 is pressed, the elastic member 4324 is compressed to store elastic potential energy, and can quickly return to its original position when the second handle plate 4322 is released. When the user presses the second handle plate 4322, the elastic element 4324 is compressed, causing the second handle plate 4322 to rotate relative to the first handle plate 4321. This, in turn, causes the positioning element 4323 to disengage from the through hole 4311, releasing the positioning state. At this time, the first handle plate 4321 is rotated to adjust to the set angle. After releasing the second handle plate 4322, it resets under the action of the elastic element 4324, pushing the positioning element 4323 back into the through hole 4311, completing the angle locking and realizing the adjustment of the airflow. Specifically, the elastic element 4324 is a spring. In other embodiments, the elastic element 4324 may also be made of other elastic materials.

[0042] Furthermore, referring to Figure 5 The adjustment handle 432 also includes a rotating shaft 4325, which is positioned between the first handle plate 4321 and the second handle plate 4322. The rotating shaft 4325 allows the second handle plate to rotate, forming a pivot point. Both ends of the rotating shaft 4325 are fixed to the first handle plate 4321 to ensure rotational stability. According to the lever principle, when one end of the second handle plate 4322 is pressed down, the other end of the second handle plate 4322 will tilt upwards via the rotating shaft 4325, thereby causing the positioning element 4323 to disengage from the through hole 4311. Specifically, the length of the pressing end of the second handle plate 4322 is greater than the length of the acting end of the second handle plate 4322. That is, when the length of the power arm is greater than the resistance arm, the user only needs to apply a small pressing force to amplify the force through the lever, driving the positioning element 4323 to disengage from the through hole 4311, reducing operator fatigue.

[0043] Furthermore, the first handle plate 4321 has a groove 4326 on the side facing the second handle plate 4322 for rotating assembly of the second handle plate 4322, so as to provide accommodating space and movement space, while reducing the thickness of the adjustment handle 432 structure.

[0044] In this embodiment, refer to Figures 3-4 and Figures 7-11 The adjustment assembly 430 also includes an indicator 440 and a marker 450. One end of the indicator 440 is located on the side of the adjustment handle 432 facing the mounting plate 431. When the adjustment handle 432 is rotated, the indicator 440 rotates synchronously, while the other end extends outward as a free end pointing towards the marker 450. The marker 450 is arc-shaped and positioned on the mounting plate 431, matching the rotation trajectory of the indicator 440. The indicator 440 rotates to point to any marker on the marker 450, allowing the user to clearly understand the airflow level. Each marker corresponds to a specific mesh overlap area and airflow value. Specifically, the surface of the marker 450 may be marked with graduations, numbers, symbols, or other markings at set angular intervals. Specifically, the indicator 440 is pointer-shaped. In other embodiments, the indicator 440 may also be other indicating components.

[0045] In this embodiment, refer to Figure 6 The sliding mechanism 300 includes a sliding base 310 and a sliding block 320. The sliding base 310 is fixedly mounted on the first plate 100; specifically, the first plate has a groove for fixing the sliding base 310. Two sliding blocks 320 are provided, one end of which is slidably fitted onto the sliding base 310, and the other end is connected to the end of the second plate 200. When the gear 420 drives the rack 410 to move, the sliding block 320 slides synchronously on the sliding base 310 along with the second plate 200.

[0046] Furthermore, the sliding block 320 has an inwardly recessed arc-shaped groove 321 through the end facing the sliding base 310, while the end of the sliding base 310 facing the sliding block 320 is an arc-shaped surface 311. The arc-shaped groove 321 is embedded in the arc-shaped surface 311 to form a curved surface contact and perform axial sliding.

[0047] The working principle of this utility model is roughly as follows: In use, one end of the positioning member 4323 is inserted into the through hole 4311 of the mounting plate 431, and the other end is fixed on the second handle plate 4322, so that the first handle plate 4321 is relatively fixed to the mounting plate 431 through the positioning member 4323. At this time, the adjusting handle 432 is in a locked state, and the air volume level remains unchanged. When it is necessary to adjust the air volume, press down on the pressing end of the second handle plate 4322 away from the rotating shaft 4325. According to the lever principle, the rotating shaft 4325 acts as a fulcrum, causing the second handle plate 4322 to rotate around the rotating shaft 4325, and the other end tilts upward. The rotation of the second handle plate 4322 causes the positioning member 4323 to disengage from the through hole 4311 of the mounting plate 431, while compressing the elastic member 4324 to store potential energy. At this point, the positioning restriction between the first handle plate 4321 and the mounting plate 431 is released. The user rotates the first handle plate 4321, which drives the gear 420 to rotate synchronously via the rotating shaft 433. The rotation of the gear 420 drives the rack 410 to move, causing the second plate 200 to slide relative to the first plate 100 to adjust the overlapping area of ​​the first mesh 110 and the second mesh 210, thereby adjusting the airflow. After releasing the second handle plate 4322, the elastic element 4324 resets and pushes the second handle plate 4322 to rotate in the opposite direction around the rotating shaft 4325, causing the positioning element 4323 to move downwards and align with the target through hole 4311 for insertion, thus relocking the position of the first handle plate 4321 and ensuring that the adjusted airflow level is stably maintained.

[0048] The above is only used to illustrate the technical solution of this utility model and not to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
