Description

Technical Field

[0001] This utility model relates to the technical field of mechanical engineering, specifically to a cooling fan frame with a turbulence structure. Background Technology

[0002] A cooling fan is a device that reduces equipment temperature by forcing airflow. It is widely used in electronics, machinery, automobiles, and home appliances. Cooling fan frames often incorporate airflow-damping structures to improve airflow efficiency. These structures typically include easily removable protective covers to protect the fan blades and facilitate maintenance. Current cooling fan frames use an outer frame and a protective cover secured by clips or bolts; the cooling fan is then mounted on the outer frame. However, the aforementioned common cooling fan frame with an airflow-damping structure still has shortcomings:

[0003] Protective covers installed using traditional snap-fit ​​methods are prone to gaps at the connection points due to wear and tear or quality issues with the snaps after a period of use. This can cause the protective cover to loosen and wobble during use, resulting in noise from collisions between the protective cover and the cooling fan frame. Utility Model Content

[0004] The purpose of this utility model is to provide a cooling fan frame with a turbulence structure to solve the problem mentioned in the background art that the protective cover installed by the traditional snap-fit ​​method is prone to gaps at the connection due to wear or quality issues of the snap-fit ​​after a period of use. This causes the protective cover to loosen and shake during use, and the collision between the protective cover and the cooling fan frame generates noise.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cooling fan frame with a turbulence structure, comprising a fan frame, mounting components at each of the four corners of the fan frame, a turbulence component fixedly connected to the back of the fan frame, four positioning slots evenly arranged on the front of the fan frame, a locking slot on one side of the inner wall of each of the four positioning slots, a protective cover assembly between the four positioning slots, and a locking mechanism for limiting the protective cover assembly inside each of the four locking slots.

[0006] Preferably, the mounting assembly includes a mounting post disposed on the fan frame, and one end of the mounting post is fixedly connected to a connecting gasket, which helps to prevent rigid connection from damaging the fan frame during secure installation.

[0007] Preferably, the turbulence component includes a horn, which is fixedly connected to the fan frame. One end of the horn is fixedly connected to multiple turbulence teeth, which helps to improve the utilization rate of air volume through the turbulence component.

[0008] Preferably, the shield assembly includes a protective shield, four positioning blocks are fixedly connected to the outer side of the protective shield, a locking slot is provided on one side of each of the four positioning blocks, a sloping abutment is fixedly connected inside each of the four locking slots, and a magnetic washer is provided on one side of the protective shield, which helps to protect the cooling fan.

[0009] Preferably, a metal ring is provided in the center of the front of the fan frame, and the surface of the magnetic washer is in contact with the surface of the metal ring.

[0010] Preferably, the locking mechanism includes a screw seat and a locking slide, both of which are disposed on a locking groove. A locking screw is rotatably connected inside the screw seat. A driven gear is fixedly connected to one end of the locking screw, and a locking slider is provided at one end of the locking screw. A locking screw hole is provided at one end of the locking slider, and the locking screw hole is threadedly connected to the locking screw. The surface of the locking slider is slidably connected to the inner wall of the locking groove, which helps to firmly hold the protective cover against the protective cover while preventing it from falling off, effectively reducing the shaking of the protective cover.

[0011] Preferably, the locking slide is internally slidably connected to a transmission toothed plate, one end of which is fixedly connected to a locking thrust block, and one side of the transmission toothed plate is meshed with one side of the driven gear.

[0012] Compared with the prior art, the beneficial effects of this utility model are: through the magnetic connection of the magnetic washer and the metal ring, and the soft material on the surface of the magnetic washer, the protective cover can be fully connected to the fan frame in a ring shape, minimizing the collision between the protective cover and the fan frame, and greatly reducing the noise caused by the loosening of the protective cover during use.

[0013] The locking mechanism secures the protective cover in four positions, preventing it from falling off. Compared to traditional buckle methods, the locking slider, once inside the locking groove, presses firmly against the inclined plate, effectively preventing the cover from detaching and minimizing its movement.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Please see Figure 1-7 This utility model provides a cooling fan frame with a turbulence structure, including a fan frame 1. Each of the four corners of the fan frame 1 is provided with a mounting component. A turbulence component is fixedly connected to the back of the fan frame 1. The front of the fan frame 1 has four positioning grooves 6, which are evenly arranged. Each of the four positioning grooves 6 has a locking groove 7 on one side of its inner wall. A protective cover component is provided between the four positioning grooves 6. Each of the four locking grooves 7 has a locking mechanism for limiting the protective cover component.

[0024] See Figure 1 and Figure 3 Furthermore, the mounting assembly includes a mounting post 2, which is mounted on the fan frame 1. One end of the mounting post 2 is fixedly connected to a connecting gasket 3. The turbulence assembly includes a horn 4, which is fixedly connected to the fan frame 1. One end of the horn 4 is fixedly connected to multiple turbulence teeth 5.

[0025] When the fan frame 1 is fixed by bolts and mounting post 2, the connecting gasket 3 contacts the wall or other fixing point and can deform when the bolts are tightened, which avoids damage to the rigid connection between the plastic mounting post 2 and the connection. In addition, the length of the mounting post 2 is greater than that of the flare 4, so it can be installed and used normally. The flare 4 with turbulence teeth 5 is installed at the air inlet. The design of the flare 4 can reduce airflow separation and turbulence. The turbulence teeth 5 can divide the airflow into small streams, suppress the formation of large-scale vortices, and reduce energy loss caused by airflow separation.

[0026] See Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7 Furthermore, the protective cover assembly includes a protective cover 16, with four positioning blocks 17 fixedly connected to the outer side of the protective cover 16. Each of the four positioning blocks 17 has a locking slot 18 on one side, and each of the four locking slots 18 has a beveled abutment plate 19 fixedly connected inside. A magnetic washer 21 is provided on one side of the protective cover 16, and a metal ring 20 is provided in the center of the front of the fan frame 1. The surface of the magnetic washer 21 contacts the surface of the metal ring 20. The locking mechanism includes a screw seat 8 and a locking slide 11, both of which are located in the locking groove. On the 7, a locking screw 9 is rotatably connected inside the screw seat 8. A driven gear 10 is fixedly connected to one end of the locking screw 9. A locking slider 14 is provided at one end of the locking screw 9. A locking screw hole 15 is provided at one end of the locking slider 14. The locking screw hole 15 is threadedly connected to the locking screw 9. The surface of the locking slider 14 is slidably connected to the inner wall of the locking groove 7. A transmission tooth plate 12 is slidably connected inside the locking slide 11. A locking push block 13 is fixedly connected to one end of the transmission tooth plate 12. One side of the transmission tooth plate 12 is meshed with one side of the driven gear 10.

[0027] In use, align the positioning block 17 on the protective cover 16 with the positioning groove 6, and install the protective cover 16. The magnetic washer 21 and the metal ring 20 will then be attracted together. The magnetic washer 21 consists of a magnetic ring with a thin layer of soft material, such as rubber or silicone, on its surface. This material will not significantly affect the magnetic ring's attraction. After installation, move the locking push block 13 to move the transmission gear plate 12. At this time, the driven gear 10 and the locking screw 9 will rotate. The rotation of the locking screw 9 will cause the locking slider 14 to move, and the locking slider 14 will move into the locking slot 18. The inclined plate 19 has an appropriate inclination relative to the horizontal plane of the locking slider 14. As the locking slider 14 moves closer to the inclined plate 19, the horizontal locking slider 14 will slowly press against the inclined plate 19, generating pressure to firmly hold the protective cover 16, preventing the protective cover 16 from falling off, and ensuring a tight connection between the fan frame 1 and the protective cover 16. Furthermore, the magnetic washer 21 is set at the connection between the protective cover 16 and the fan frame 1, which can minimize the possibility of the protective cover 16 loosening and greatly reduce the noise generated by the protective cover 16 loosening during the operation of the cooling fan.

[0028] In this embodiment, during installation, it is necessary to ensure that the transmission gear plate 12 and the driven gear 10 are meshed. The locking slider 14 has a rounded corner at one end inserted into the locking slot 18, ensuring that it can only be firmly engaged after partially entering the locking slot 18, preventing the protective cover 16 from falling off. Under normal operating conditions of the cooling fan, the magnetic washer 21 remains attracted to the metal ring 20, ensuring that the protective cover 16 does not generate excessive noise. Some traditional cooling fan protective covers 16 are only connected by two clips, which can easily cause the cover 16 to shake or even deform after a period of time. This generates noise, and the deformed cover 16 may affect the airflow output. Compared to the traditional clip method, this device, after the locking slider 14 enters the locking groove 7, tightly abuts against the inclined plate 19, effectively preventing the protective cover 16 from falling off and firmly holding it in place, thus reducing the shaking of the protective cover 16.

[0029] Although the present invention 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 invention should be included within the protection scope of the present invention.
