Description

Technical Field

[0001] This utility model relates to the field of fan bracket technology, and in particular to a shock-absorbing fan bracket. Background Technology

[0002] A fan is a device that uses a motor to drive blades to rotate and promote airflow. It is used for indoor and outdoor air exchange or equipment cooling, and to improve airflow distribution in a space. The fan is supported by a bracket, which prevents the fan from shifting due to its own weight or vibration and installs the fan in a designated position.

[0003] Chinese patent discloses a cooling fan (authorization announcement number CN212744418U). This patented technology includes a drive motor, fan blades, a fan frame, and a power cord. The fan frame includes an outer frame and a central cover for connecting to the drive motor. One end of the power cord is disposed within the central cover, and the other end has a plug. The plug is detachably connected to the outer frame. The central cover includes a support rod for connecting to the outer frame, and the support rod has a wire-fixing part for securing the power cord. The outer frame has an opening corresponding to the support rod for the power cord to pass through, and the central cover has an outlet corresponding to the support rod for the power cord to exit. A cord-retracting mechanism is provided between the central cover and the drive motor. By adopting the above technical solution, compared to the fixed power cord length of pluggable cooling fans in the prior art, this technical solution allows the power cord to be pulled out from the cord-retracting device, thereby adjusting the power cord length to adapt to different usage conditions.

[0004] While the patented technology allows for easy adjustment of the power cord length during use, it still has shortcomings. When the fan blades cut the airflow, they generate periodic pressure pulsations, which can lead to loosening of the fixing parts over time. The loose fixing parts cause friction and noise, increasing the wear and tear on the equipment. Therefore, those skilled in the art have provided a shock-absorbing fan bracket to solve the problems mentioned in the background art. Utility Model Content

[0015] Furthermore, the outer wall of the card cover is provided with equidistantly distributed through holes, and the inner wall of the card cover is provided with equidistantly distributed rubber card holders in a semi-circular shape;

[0016] Specifically, the through holes allow airflow to pass through, the inside and outside of the cover allow airflow to circulate, and the rubber brackets hold the outer wall of the motor in place.

[0023] 2. Beneficial effects

[0024] Compared with existing technologies, the advantages of this utility model are:

[0025] In this invention, the fan body is installed inside the inner bracket and fixed in a designated position by the outer bracket. A spring arranged in a ring array is set between the outer bracket and the inner bracket. When the fan operates, the vibration generated acts on the spring, causing the spring to contract or stretch. When the spring contracts or stretches, the piston moves inside the mounting cylinder and squeezes the hydraulic oil. When the hydraulic oil passes through the oil gap, the narrow oil gap applies resistance to the hydraulic oil, and the rubber ring is forced open, allowing the hydraulic oil to flow in different chambers, applying a damping effect to the spring, playing a role in buffering and shock absorption, thereby reducing noise and wear on parts, and thus extending the service life of the equipment.

[0026] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0041] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0042] Example 1

[0043] Please see Figures 1-5 As shown, this embodiment is a shock-absorbing fan bracket, including a main structure 100 and a shock-absorbing structure 200.

[0044] The main structure 100 includes an outer bracket 101 and an inner bracket 102 that are sleeved together, a fan body 104 fixed inside the inner bracket 102, and a motor 105 whose output end is connected to the rotating shaft of the fan body 104.

[0045] The shock-absorbing structure 200 includes a mounting cylinder 211 located between the outer support 101 and the inner support 102 and arranged in a ring array, a sealing ring 205 embedded in the mounting cylinder 211, a plug rod 209 slidably inserted into the sealing ring 205, a piston 208 located at one end of the plug rod 209 and slidably inserted into the mounting cylinder 211, an annular oil gap located between the piston 208 and the mounting cylinder 211, hydraulic oil filled inside the mounting cylinder 211, and a spring 204 sleeved on the outside of the mounting cylinder 211 and the plug rod 209.

[0046] Mounting holes 103 are provided inside at all four corners of the outer bracket 101;

[0047] The plug rod 209 and the mounting cylinder 211 are both provided with a second docking block 202 at the opposite end. The outer bracket 101 and the inner bracket 102 are both provided with a first docking block 201 arranged in a ring array at the opposite end. Bolts 203 are provided inside the first docking block 201 and the second docking block 202. The two ends of the spring 204 are fixed between the second docking blocks 202.

[0048] The mounting cylinder 211 has a hole 207 at its opening that fits onto the outside of the plug rod 209. The inner wall of the mounting cylinder 211 has a ring-shaped support ring 206 that fits into the lower end of the sealing ring 205. The outer wall of the piston 208 is fitted with a rubber ring 210 that fits into the inner wall of the mounting cylinder 211.

[0049] The vibration damping structure 200 is used;

[0050] Motor 105 drives fan body 104 to rotate. During operation, the blades cut the airflow, generating periodic pressure pulsations, which cause fan body 104 to vibrate. The vibration energy is transmitted through inner bracket 102 to mounting cylinder 211 of shock-absorbing structure 200. Spring 204 extends and retracts under force, and piston 208 inside mounting cylinder 211 slides in hydraulic oil with the vibration. When piston 208 moves into mounting cylinder 211, hydraulic oil flows slowly through the annular oil gap between piston 208 and inner wall of mounting cylinder 211. When piston 208 moves in the opposite direction, the pressure increases, and the rubber... The ring plate 210 deforms under the pressure of hydraulic oil, expanding the oil passage and preventing excessive damping force from causing rigid impact. When the pressure is low, it returns to its original shape, maintaining basic damping and allowing oil to pass through, forming a bidirectional damping effect. Under the alternating action of the oil gap and the rubber ring plate 210, the hydraulic oil converts the vibration kinetic energy into heat energy. When the fan body 104 is in use, it plays a role in shock absorption and noise reduction, preventing fixed parts from being directly subjected to vibration impact, and protecting the structural components. The stability of the structural components is improved during use, and the service life of the fan body 104 and the bracket structure is extended.

[0051] Example 2

[0052] Please see Figures 1-5 As shown, this embodiment, based on embodiment 1, also includes a noise reduction structure 300.

[0053] The noise reduction structure 300 includes symmetrically distributed clips 302 that are sleeved on the outside of the motor 105 and are relatively distributed.

[0054] The outer wall of the card cover 302 is provided with equally spaced through holes 303, and the inner wall of the card cover 302 is provided with equally spaced and semi-circular rubber card seats 305.

[0055] Each end of the cover 302 is provided with an installation port 306 that is sleeved on the outside of the output shaft of the motor 105, and multiple sets of sound insulation sheets 307 are provided between the rubber card seats 305.

[0056] Both ends of the cover 302 are provided with mounting brackets 301, and the interior of the mounting brackets 301 and the interior of the outer bracket 101 are provided with corresponding holes 304.

[0057] The noise reduction structure 300 is used;

[0058] When the motor 105 is installed, the cover 302 is fitted onto the outside of the motor 105. The cover 302 is fixed to the outer bracket 101 by the mounting bracket 301. The vibration of the motor 105 is transmitted through the rubber bracket 305. The sound insulation sheet 307 absorbs the high-frequency vibration sound waves. The through hole 303 on the outer wall of the cover 302 allows airflow to pass through, so as to cool the motor 105. The cover 302 and the motor 105 are flexibly connected by the rubber bracket 305, which blocks the vibration transmission path, reduces the noise of the motor 105 during operation, and improves the operating environment of the fan body 104.
