[0022] Example 1:

The connecting ear 6 is provided with an exhaust groove 13, and the connecting ear 6 is fixedly installed with a buffer rubber sleeve 14. A rubber pad 15 is fixedly installed between the connecting seat 3 and the spring piece 5. The spring piece 5 is made of stainless steel. The connecting seat 3 is fixedly connected to the assembly seat 2 by a second bolt 16.

[0024] Through the above technical solution, the outer frame 1 of the utility model is provided with an assembly seat 2, the assembly seat 2 is fixedly installed with a connecting seat 3, and the connecting seat 3 is fixedly connected to the inner frame 7 through the spring clip 5, so that the outer frame 1 is fixedly connected to the inner frame 7 through the spring clip 5 to achieve the vibration filtering effect, and the inner frame 7 is fixedly installed with a motor 8, and the motor 8 drives the fan blades 9 to rotate. When the cooling fan is running, the vibration generated by the rotation of the fan blades 9 driven by the motor 8 of the inner frame 7 is filtered through the spring clip 5 to prevent abnormal noise and improve the user experience.

[0025] Example 2:

[0026] like Figures 1-6As shown, the outer frame 1 of the present invention provides support and protection for the entire cooling fan. It is used to securely mount the cooling fan in the computer case, ensuring stability during operation. The stability of the outer frame 1 has a direct impact on the cooling fan's performance and user experience. The outer frame 1 is provided with an assembly base 2, to which a connecting base 3 is fixedly mounted. A spring clip 5 is secured to the connecting base 3 via a first bolt 4. The spring clip 5 is a component made of elastic material that effectively absorbs and mitigates vibrations generated during the cooling fan's operation. Since the cooling fan generates a certain amount of vibration when operating at high speeds, if not controlled, this vibration may be transmitted through the outer frame 1 into the computer case, causing unusual noise and impacting the user experience. By securely connecting the spring clip 5 to the connecting base 3, these vibrations are filtered during cooling fan operation, reducing noise generation. The bottom of the connecting base 3 is provided with a connector hole 12, which mates with a connector post 11 on the outer frame 1. The connection between the plug post 11 and the plug hole 12 secures the connector 3 securely to the assembly base 2, ensuring that the connector 3 does not shift or loosen during operation of the cooling fan. This secure connection not only improves the reliability of the cooling fan but also further reduces noise caused by loosening. At the other end of the spring clip 5, it is fixedly connected to the inner frame 7 via a connecting ear 6. Inside the inner frame 7 are the core components of the cooling fan, including the motor 8 and blades 9. The motor 8 is responsible for driving the blades 9 to rotate, generating airflow for effective cooling. The design of the blades 9 directly affects the cooling fan's air volume and pressure, thereby affecting the computer's cooling performance. The structure of the inner frame 7 must ensure effective cooling while avoiding resonance caused by vibration. The connection between the inner frame 7 and the outer frame 1 via the spring clip 5 creates an effective buffer structure. In this structure, the elastic properties of the spring clip 5 absorb some vibrations during operation of the cooling fan, preventing these vibrations from propagating through the outer frame 1. This structural design plays a crucial role in noise reduction and significantly improves the user experience when using the computer.

[0027] The connecting ear 6 of the present invention is provided with an exhaust groove 13. This structure helps reduce the impact of air pressure on installation during the assembly process. The design of the exhaust groove 13 allows air inside the connecting ear 6 to be effectively discharged during the assembly of the spring clip 5 and the cushioning rubber sleeve 14, making installation of the spring clip 5 and the cushioning rubber sleeve 14 smoother. This not only helps reduce resistance during the assembly process, but also ensures that the spring clip 5 and the connecting ear 6 can better mate and ensure a tight fit. The cushioning rubber sleeve 14 is fixedly installed in the connecting ear 6, wrapping the spring clip 5 to form a flexible connection. This flexible connection has significant advantages. First, it can further filter the vibration generated by the operation of the cooling fan. When the cooling fan is running at high speed, the rotation of the motor 8 and the fan blades 9 will cause a certain amount of vibration. If effective measures are not taken, this vibration may be transmitted through the connecting ear 6 to other components, generating noise and affecting the user experience. By using the cushioning rubber sleeve 14, the connection between the spring clip 5 and the connecting ear 6 is transformed into a more gentle connection, which can significantly reduce the transmission of vibration. Furthermore, the flexible connection improves the lifespan of the connection between the spring clip 5 and the connecting lug 6. Traditional rigid connections are susceptible to fatigue and wear when subjected to long-term vibration, ultimately leading to loosening or breakage of the connection. However, the flexible connection provided by the buffer rubber sleeve 14 effectively absorbs and disperses the stress caused by vibration during use, reducing direct impact on the connection, lowering the probability of wear, and extending the service life of the entire system. The flexible nature of the buffer rubber sleeve 14 allows the spring clip 5 to move slightly during operation, adapting to different vibration modes, thereby avoiding the stress concentration caused by a fixed connection.

[0028] A rubber pad 15 is fixedly mounted between the connector 3 and the spring clip 5 of the present invention. The primary function of the rubber pad 15 is to dampen vibrations from the spring clip 5, preventing any unusual noises from occurring between the connector 3 and the spring clip 5 when the cooling fan is operating. The high-speed rotation of the motor 8 and blades 9 during cooling fan operation generates a certain degree of vibration. If left uncontrolled, this vibration can be transmitted through the connector 3 to other components, creating noise and impacting the user experience. The rubber pad 15 is made of rubber or a polymer. The choice of these materials not only ensures the stability of the rubber pad 15 during long-term use but also allows it to withstand the vibration and pressure from the spring clip 5, thereby physically blocking the propagation of vibrations. The mounting position of the rubber pad 15 is crucial. Fixed between the connector 3 and the spring clip 5, it effectively disperses vibrations and reduces direct vibration transmission, resulting in a smoother contact between the connector 3 and the spring clip 5. When the cooling fan is operating, the vibrations generated by the movement of the motor 8 are transmitted to the connector 3 via the spring clip 5. Without effective damping measures between the connector 3 and the spring clip 5, the vibrations are transmitted with high intensity, causing noise. The function of the rubber pad 15 is to provide a barrier mechanism, effectively absorbing the vibration of the spring 5 when it contacts the connector 3, reducing the concentration of vibration at the connection point and thus reducing the incidence of noise. Furthermore, the use of the rubber pad 15 has a positive impact on the durability of the connector 3 and the spring 5. Without the cushioning provided by the rubber pad 15, the rigid connection between the connector 3 and the spring 5 would easily wear out under long-term vibration, and the connection might even become loose or break. The cushioning properties of the rubber pad 15 can effectively reduce friction between the connecting components, thereby extending the service life of the entire system. By reducing the frequency of wear, the rubber pad 15 ensures that the connector 3 and the spring 5 can maintain a stable connection for a long time. During the operation of the cooling fan, the rubber pad 15 also serves as a protective device. Because the rubber pad 15 has a certain degree of elasticity and toughness, it can resist external impact forces to a certain extent. This cushioning property allows the rubber pad 15 to absorb some of the impact force when the fan is subjected to accidental impact or vibration.

[0029] The spring clip 5 of the present invention is made of stainless steel, a material with excellent mechanical properties, particularly in terms of elasticity, corrosion resistance, and durability. Using stainless steel significantly improves the spring clip 5's elasticity, enabling it to effectively absorb and filter vibrations during cooling fan operation, ensuring stable operation of the entire cooling system. The elastic properties of stainless steel enable the spring clip 5 to quickly return to its original shape when subjected to external forces. This rapid recovery is crucial for cooling fan operation, as the fan is subject to vibrations generated by the rotation of the motor 8 and blades 9. If the spring clip 5 fails to effectively absorb these vibrations, they may be transmitted to the connector 3 and other components, causing noise. Using stainless steel allows the spring clip 5 to better absorb vibrations, significantly reducing the intensity of the transmitted vibrations and the incidence of noise. The corrosion resistance of stainless steel also ensures the long-term use of the spring clip 5. In computer cooling systems, the spring clip 5 may be exposed to moisture and other corrosive environments. The chemical stability of stainless steel allows it to resist oxidation and corrosion, extending the service life of the spring clip 5.

[0030] The connecting base 3 of the present invention is fixedly connected to the assembly base 2 via a second bolt 16. The connection between the connecting base 3 and the assembly base 2 not only relies on the plug-in fixation of the plug-in post 11 and the plug-in hole 12, but the second bolt 16 also further enhances the robustness of this connection. This design ensures the stability of the connecting base 3 during operation, preventing loosening of the connection due to vibration or external impact, thereby increasing the service life of the cooling fan. The second bolt 16 provides a mechanical locking mechanism between the connecting base 3 and the assembly base 2, further tightening the connection. During operation of the cooling fan, the rotation of the motor 8 and the fan blades 9 generates a certain amount of vibration. If this vibration is not controlled, it can potentially damage the connection. The use of the second bolt 16 for securing the connection effectively prevents loosening of the connection due to vibration. The fixing action of the bolt creates a solid bond between the connecting base 3 and the assembly base 2, thereby enhancing the overall structure's earthquake resistance. The connection between the plug-in post 11 and the plug-in hole 12 between the connecting base 3 and the assembly base 2 also provides support and positioning. The design of the plug post 11 ensures the accurate positioning of the connector 3 within the assembly base 2, allowing the components to achieve optimal docking during assembly. In this structure, the plug post 11 not only provides necessary support but also simplifies the assembly process during connection, reducing errors caused by human factors. Furthermore, the combination of the plug post 11 and the socket 12 disperses stress at the connection point, making the entire cooling system more stable during use.
