[0003] Existing computer cases have ventilation slots on their surfaces, but their structure and function are very limited, serving only as a cooling mechanism for air exchange. However, the presence of these ventilation slots means that the inside of the case is always connected to the outside, causing a significant amount of noise generated inside the case to be transmitted to the outside, resulting in noise pollution of the working environment and harming the physical and mental health of employees. Therefore, it is necessary to develop a new type of cooling and noise reduction device for computer cases to address the shortcomings of existing technologies. Utility Model Content

[0012] Preferably, the drive assembly includes a linkage frame that is slidably engaged with the back of the chassis cavity.

[0023] 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.

[0024] like Figures 1 to 6As shown, this utility model provides a computer cooling and noise reduction device, including a chassis 1. An air intake component 2 is fixedly embedded in the lower end of one side of the chassis 1, and an exhaust component 3 is fixedly embedded in the upper end of the other side of the chassis 1. The near ends of the air intake component 2 and the exhaust component 3 are connected to the interior of the chassis 1, and the far ends of the air intake component 2 and the exhaust component 3 are connected to the outside. A drive component 4 is installed inside the chassis 1.

[0025] The intake assembly 2 and exhaust assembly 3 have the same structure. Both consist of a sealing cover 21, a ventilation chamber 22, a ventilation slot 23, and two one-way exhaust plates 24 that are slidably engaged inside the ventilation chamber 22. The sealing cover 21 is fixedly embedded inside the chassis 1. The ventilation chamber 22 is located inside the sealing cover 21 on the side closer to the center of the chassis 1. The ventilation slot 23 is located inside the sealing cover 21 on the side away from the center of the chassis 1. One one-way exhaust plate 24 is fixedly installed inside the ventilation chamber 22 on the side away from the center of the chassis 1, and the other one-way exhaust plate 24 is slidably engaged inside the ventilation chamber 22. The one-way exhaust plates 24 inside the exhaust assembly 3 have opposite one-way flow directions. The two ends of the drive assembly 4 are respectively connected to the two one-way exhaust plates 24 inside the intake assembly 2 and exhaust assembly 3, which are close to and slidably engaged inside the ventilation chamber 22. Due to the arrangement of the intake assembly 2 and exhaust assembly 3, with the cooperation of the drive assembly 4, the intake assembly 2 and exhaust assembly 3 can continuously exchange the air inside the chassis 1 with the outside air to achieve the cooling effect. At the same time, with the cooperation of the intake assembly 2 and exhaust assembly 3, the chassis 1 is always kept closed to the outside, which can prevent the noise inside the chassis 1 from leaking out, thereby achieving the effect of effectively reducing noise.

[0026] like Figure 4 As shown, the distance between the side of the ventilation chamber 22 closest to the center of the chassis 1 and the other side is greater than the width of the one-way exhaust plate 24. The cross-section of the ventilation slot 23 in the intake assembly 2 and the exhaust assembly 3 is inclined, and the extension lines of the center lines of the ventilation slot 23 in the intake assembly 2 and the exhaust assembly 3 intersect.

[0027] like Figure 2 and Figure 4 As shown, external air enters the interior of the chassis 1 at an angle upward along the ventilation slot 23 in the air intake assembly 2, and the air inside the chassis 1 is discharged at an angle downward along the ventilation slot 23 in the exhaust assembly 3. Due to the setting of the ventilation slot 23, it can ensure that the air inside the chassis 1 can circulate with the outside, and can effectively reduce the situation where dust in the external air falls into the ventilation slot 23 and then enters the chassis 1, thus effectively reducing the dust accumulation rate inside the chassis 1.

[0028] like Figures 4 to 6As shown, the one-way exhaust plate 24 includes a linkage slide plate 241 that is snapped into the air exchange chamber 22. One linkage slide plate 241, which is far from the center of the chassis 1, is fixedly installed inside the air exchange chamber 22, and the other linkage slide plate 241, which is close to the center of the chassis 1, is slidably snapped into the air exchange chamber 22. Due to the cooperation of the two linkage slide plates 241, the air in the air exchange chamber 22 and the ventilation slot 23 can always flow continuously in one direction with the cooperation of their respective corresponding adapter slots 242, ventilation openings 243 and sealing plates 244. At the same time, it ensures that the end of the air exchange chamber 22 that is close to the center of the chassis 1 is always disconnected from the ventilation slot 23, thereby preventing the noise inside the chassis 1 from being transmitted out.

[0029] like Figures 4 to 6 As shown, an adapter groove 242 is provided on the side of the linkage slide plate 241 in the air intake assembly 2 near the center of the chassis 1, and an adapter groove 242 is provided on the side of the linkage slide plate 241 in the air intake assembly 2 away from the center of the chassis 1. A number of evenly distributed vents 243 are provided on both the side of the linkage slide plate 241 in the air intake assembly 2 away from the center of the chassis 1 and the side of the linkage slide plate 241 in the exhaust assembly 3 near the center of the chassis 1. A number of evenly distributed sealing plates 244 are hinged inside the adapter groove 242. The sealing plates 244 correspond one-to-one with the vents 243, and the sealing plates 244 are sealed and fitted to one end of the vents 243. The adapter groove 242 provides space for the sealing plates 244 to flip, and the vents 243, with the cooperation of the sealing plates 244 and the magnetic block 245, achieve an intermittent through-flow effect, thereby ensuring that the air on both sides of the linkage slide plate 241 can flow continuously in one direction.

[0030] like Figures 4 to 6 As shown, one side of the sealing plate 244 is movably hinged to the inside of the adapter groove 242, and magnetic blocks 245 are embedded in the other side of the sealing plate 244 and the inner wall of the vent 243. The sealing plate 244 is tightly attached to the end of the vent 243 by the two magnetic blocks 245. Due to the setting of the magnetic blocks 245, it is ensured that the sealing plate 244 can be tightly attached to one end of the vent 243. At the same time, when the linkage slide plate 241 moves back and forth to generate negative pressure, it can ensure that the sealing plate 244 is disengaged from the magnetic attraction of the magnetic blocks 245 and moves away from the vent 243.

[0031] like Figures 1 to 3As shown, the drive assembly 4 includes a linkage frame 41 that is slidably engaged with the back of the inner cavity of the chassis 1. The upper and lower ends of the linkage frame 41 extend to the intake assembly 2 and the exhaust assembly 3 and are fixedly connected to a linkage slide plate 241 that is slidably engaged with the intake assembly 2 and the exhaust assembly 3, respectively. A drive motor 42 is provided on the front of the linkage frame 41. A fixing ring 46 is fixedly sleeved on the outside of the drive motor 42. A support block 47 is integrally formed on the back of the fixing ring 46 and is fixedly connected to the chassis 1. Due to the setting of the linkage frame 41, the two unidirectional exhaust plates 24 that are slidably engaged with the intake assembly 2 and the exhaust assembly 3 can move left and right synchronously, so that with the cooperation of their respective other unidirectional exhaust plates 24, the air in the intake assembly 2 and the exhaust assembly 3 always flows continuously in one direction.

[0032] like Figures 1 to 3 As shown, a linkage limiting groove 43 is provided in the middle of the linkage frame 41, located on the back of the drive motor 42. A drive wheel 44 located on the front of the linkage limiting groove 43 is fixedly connected to the rear end of the output shaft of the drive motor 42. An eccentric shaft 45 is fixedly connected to the edge of the drive wheel 44. The outer surface of the eccentric shaft 45 is sleeved inside the linkage limiting groove 43 via a bearing. The major axis dimension of the linkage limiting groove 43 is greater than twice the center distance between the eccentric shaft 45 and the drive wheel 44. Due to the setting of the linkage limiting groove 43, the drive wheel 44 and... With the cooperation of the eccentric shaft 45, the linkage frame 41 can always move smoothly back and forth, thereby driving the one-way exhaust plate 24, which is slidably installed in the intake assembly 2 and the exhaust assembly 3, to move back and forth. Since the length of the vent 243 is more than twice the center distance between the eccentric shaft 45 and the drive wheel 44, it is ensured that the eccentric shaft 45 will not collide with the upper and lower ends of the inner wall of the linkage limit groove 43 when it moves to the highest or lowest point, thereby ensuring that the drive wheel 44 and the eccentric shaft 45 can drive the linkage frame 41 to move smoothly back and forth.

[0033] Working principle and usage process of this utility model:

[0034] like Figure 1 When assembling the equipment, turning on the drive motor 42 will drive the eccentric shaft 45 to rotate continuously around its axis via the drive wheel 44. In turn, the linkage frame 41, which is slidably engaged with the inner wall of the chassis 1, will move back and forth under the cooperation of the external sleeve bearing and the linkage limit groove 43. As a result of the movement of the linkage frame 41, a one-way exhaust plate 24 near the center of the chassis 1 in the air intake assembly 2 and the exhaust assembly 3 will move back and forth along the inside of the ventilation chamber 22.

[0035] Due to the reciprocating movement of a one-way exhaust plate 24 near the center of the chassis 1 within the intake assembly 2, specifically the reciprocating movement of the linkage slide plate 241 along the interior of the ventilation chamber 22, when the linkage slide plate 241 slowly moves towards the center of the chassis 1, it can, with the cooperation of the sealing plates 244 on its surface, push the air inside the ventilation chamber 22 into the interior of the chassis 1. At the same time, the distance between the two one-way exhaust plates 24 gradually increases, forming a negative pressure. This causes the external air to push several sealing plates 244 on the surface of the linkage slide plate 241, which is away from the center of the chassis 1, so that their inner and outer sides are connected. When the air is vented, external air can enter between the two one-way exhaust plates 24 in the ventilation chamber 22. When the linkage slide plate 241 moves slowly away from the center of the chassis 1, the air between the two one-way exhaust plates 24 can be pushed by the compression of the one-way exhaust plate 24 away from the center of the chassis 1 to a number of sealing plates 244 on the surface of the linkage slide plate 241 near the center of the chassis 1. This part of the air enters the side of the one-way exhaust plate 24 near the center of the chassis 1 inside the ventilation chamber 22, so that it can be pushed into the chassis 1 when the one-way exhaust plate 24 near the center of the chassis 1 moves again.

[0036] In summary, under the drive of the drive component 4, the one-way exhaust plate 24 that moves back and forth in the intake component 2 can, with the cooperation of a fixed one-way exhaust plate 24, enable the intake component 2 as a whole to continuously draw external air into the interior of the chassis 1 while both ends are always disconnected.

[0037] Similarly, under the drive of the drive component 4, the one-way exhaust plate 24 that moves back and forth in the exhaust component 3 can, with the cooperation of a fixed one-way exhaust plate 24, enable the exhaust component 3 as a whole to continuously exhaust the air inside the chassis 1 to the outside air in a state where both ends are always disconnected.

[0038] In summary, the internal drive component 4 of the chassis 1 can achieve continuous air exchange and cooling through the intake component 2 and exhaust component 3, while keeping the interior of the chassis 1 closed to the outside, thus preventing noise leakage.
