Description

Technical Field

[0001] This utility model relates to the field of DC fan technology, and in particular to a DC fan with vibration reduction function. Background Technology

[0002] With the rapid development of electronic products, DC fans, as a commonly used heat dissipation electrical product in the mechanical and electronic industry, refer to fans that convert DC electrical energy into mechanical energy by inputting DC electrical energy, causing a DC motor to rotate and driving the fan impeller to rotate. Its core feature is the selection of DC motors, mostly brushless DC motors, which have advantages such as simplified structure, enhanced mechanical reliability, increased lifespan, small size, light weight, and excellent control performance. However, the operation of DC fans will bring vibration and noise. Most DC fans on the market do not have direct or indirect vibration damping structures. During use, the vibration of DC fans will generate noise and loosen parts, thus affecting their service life. DC fans with vibration damping structures are mostly complex in structure and have high assembly costs. Utility Model Content

[0003] The purpose of this invention is to provide a DC fan with shock absorption function to solve the problems of excessive vibration and noise in DC fans.

[0004] The technical solution adopted by the above-mentioned utility model is as follows: a DC fan with shock absorption function, including a fan assembly, a shock absorption assembly, and a housing. The fan assembly includes a DC fan, a bearing, and a mounting base. A first partition is provided on the front side of the fan assembly, and a second partition is provided on the rear side of the fan assembly. The shock absorption assembly includes a shock absorption sleeve and a shock absorption connector. The first partition and the second partition are movably connected. The shock absorption sleeve wraps around the sides of the first partition and the second partition. The shock absorption connector is provided on the side of the shock absorption sleeve away from the first partition. One end of the shock absorption connector is fixedly connected to the outside of the shock absorption sleeve, and the other end of the shock absorption connector is fixedly connected to the inside of the housing.

[0005] Furthermore, the mounting base is disposed on the side of the second partition near the first partition, the bearing is disposed on the mounting base, and the DC fan is disposed on the other side of the bearing.

[0006] Furthermore, the first partition and the second partition are of the same size, and the first partition and the second partition are fitted and connected to the shock-absorbing sleeve.

[0007] Furthermore, four shock-absorbing connectors are provided, and the shock-absorbing connectors are respectively provided on the upper, lower, left, and right sides of the shock-absorbing sleeve.

[0008] Furthermore, both the shock-absorbing sleeve and the shock-absorbing connector are made of silicone, and the shock-absorbing connector is in a spiral shape.

[0009] Furthermore, a sound-emitting hole is provided on the side of the second partition away from the first partition, and the sound-emitting hole is located at the center of the second partition.

[0010] Furthermore, both the first partition and the second partition are arranged in a star-shaped pattern.

[0011] Furthermore, the housing is shaped like a square, and dustproof nets are provided on the front and rear sides of the housing, and the dustproof nets are configured as mesh structures.

[0012] This invention uses the cooperation of a first partition and a second partition to clamp a DC fan in the middle of the two partitions, and then connects them with a bearing, thus separating the DC fan from the housing and reducing the impact of DC fan vibration. Furthermore, by wrapping the outside of the first and second partitions with a shock-absorbing sleeve and a shock-absorbing connector, the silicone properties of the sleeve and connector are utilized for vibration damping. The spiral shape of the shock-absorbing connector further enhances the vibration damping effect of the DC fan and reduces noise. The presence of a pre-configured sound hole allows the sound hole to emit an anti-phase sound wave equal to the fan's operating noise during operation, thereby enhancing the noise reduction capability of the DC fan.

[0022] See appendix Figure 1 To be continued Figure 3 The figure shows a specific embodiment of a DC fan with shock absorption function provided by the utility model.

[0023] See appendix Figure 1 In the above embodiments, a DC fan with vibration damping function includes a fan assembly 1, a vibration damping assembly 2, and a housing 3. The fan assembly 1 includes a DC fan 101, a bearing 102, and a mounting base 103. A first partition 4 is provided on the front side of the fan assembly 1, and a second partition 5 is provided on the rear side of the fan assembly 1. The vibration damping assembly 2 includes a vibration damping sleeve 201 and a vibration damping connector 202. The first partition 4 and the second partition 5 are movably connected. The vibration damping sleeve 201 wraps around the sides of the first partition 4 and the second partition 5. The vibration damping connector 202 is provided on the side of the vibration damping sleeve 201 away from the first partition 4. One end of the vibration damping connector 202 is fixedly connected to the outside of the vibration damping sleeve 201, and the other end of the vibration damping connector 202 is fixedly connected to the inside of the housing 3.

[0024] See appendix Figure 1 In the above embodiment, the mounting base 103 is disposed on the side of the second partition 5 near the first partition 4, the bearing 102 is disposed on the mounting base 103, and the DC fan 101 is disposed on the other side of the bearing 102. Through the cooperation of the first partition 4 and the second partition 5, the DC fan 101 is clamped in the middle position of the first partition 4 and the second partition 5, and then connected by the bearing 102, so that the DC fan 101 is separated from the housing 3, reducing the impact of the vibration of the DC fan 101, thereby playing a role in shock absorption.

[0025] See appendix Figure 1In the above embodiment, the first partition 4 and the second partition 5 are of equal size. The first partition 4 and the second partition 5 are fitted and connected to the shock-absorbing sleeve 201. By setting the first partition 4 and the second partition 5 to be of equal size, the first partition 4 and the second partition 5 can be easily fixed and connected to fix the DC fan 101 in the middle position. At the same time, the shock-absorbing sleeve 201 can be fitted and connected to the first partition 4 and the second partition 5 to achieve a certain shock absorption effect.

[0026] See appendix Figure 2 In the above embodiment, four shock-absorbing connectors 202 are provided. The shock-absorbing connectors 202 are respectively provided on the upper, lower, left and right sides of the shock-absorbing sleeve 201. By providing shock-absorbing connectors 202 on the upper, lower, left and right sides of the shock-absorbing sleeve 201, the shock absorption function of the DC fan 101 is further improved.

[0027] See appendix Figure 1 and attached Figure 2 In the above embodiment, both the shock-absorbing sleeve 201 and the shock-absorbing connector 202 are made of silicone. The shock-absorbing connector 202 is in a spiral shape. By making both the shock-absorbing sleeve 201 and the shock-absorbing connector 202 of silicone, the silicone properties of the shock-absorbing sleeve 201 and the shock-absorbing connector 202 are utilized for shock absorption. At the same time, the silicone material of the shock-absorbing sleeve 201 can better protect the internal structure of the DC fan 101. By making the shock-absorbing connector 202 of a spiral shape, the shock-absorbing effect of the DC fan 101 is enhanced by utilizing the damping properties of the spiral shape of the shock-absorbing connector 202, while also reducing noise.

[0028] See appendix Figure 2 In the above embodiment, a sound-emitting hole 8 is provided on the side of the second partition 5 away from the first partition 4. The sound-emitting hole 8 is located at the center of the second partition 5. By using the sound-emitting hole 8, the sound-emitting hole 8 can emit a sound wave with the same phase as the fan noise when the fan is running. By emitting a sound wave with the same frequency and amplitude as the noise, the two interfere with each other and cancel each other out during propagation, thereby reducing the noise intensity of the DC fan 101 and thus enhancing the noise reduction capability of the DC fan 101.

[0029] See appendix Figure 3 In the above embodiments, the first partition 4 and the second partition 5 are both arranged in a star shape. By setting the first partition 4 and the second partition 5 in a star shape, the structural characteristics of the star shape are strong and not easily deformed. This allows the first partition 4 and the second partition 5 to provide strong support for the internal structure of the DC fan 101 and to protect and isolate the DC motor, thereby extending the service life of the equipment.

[0030] See appendix Figure 1 In the above embodiment, the housing 3 is arranged in a U-shape, and dustproof nets 6 are provided on the front and rear sides of the housing 3. The dustproof nets 6 are set as mesh structures. By setting the dustproof nets 6, it is possible to avoid injury to personnel caused by human contact during use, and to prevent dust from entering and affecting the normal operation of the equipment.

[0031] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
