Description

Technical Field

[0001] The utility model relates to the technical field of radiator design, in particular to a fan shock-absorbing bracket and a heat dissipation fan. Background Art

[0002] In the field of radiator design, in order to improve the heat dissipation efficiency of the radiator, a cooling fin group is usually used in combination with a cooling fan, that is, the airflow generated by the cooling fan takes away the heat emitted by the cooling fins, thereby achieving the purpose of rapid heat dissipation. Generally, the cooling fan is installed on the outside of the cooling fin group. In some dual-tower radiators, the cooling fan is installed between the two cooling fin groups. The installation methods between the cooling fan and the cooling fin group generally include: screws, elastic steel wires, buckles, etc.

[0003] The common installation method is to install the cooling fan and the cooling fin group by screws. The screws are inserted into the through holes on the side of the cooling fan bracket (commonly found at the four corners of the bracket), and then the tail ends of the screws are connected to the screw holes on the cooling fin group. This design has the following disadvantages:

[0004] 1. In order to reserve installation margin, the aperture of the through hole on the bracket of the cooling fan usually needs to be slightly larger than the diameter of the screw shaft. Therefore, during assembly, the screw shaft needs to be tightly connected to the screw hole on the cooling fin group, and the axial pressure is used to generate a large friction between the head of the screw and the bracket of the cooling fan to prevent the bracket of the cooling fan from radially offset. If the screw is loose, the cooling fan is likely to loosen and offset relative to the cooling fin group; if the screw is tightened too much, the through hole of the bracket of the cooling fan is easily crushed. There are problems of high difficulty in operation and low reliability.

[0005] 2. To ensure the stability of the fan during operation, the bracket of the cooling fan is usually a rigid structure (such as a common hard plastic frame). Therefore, after the screws, cooling fan bracket, and cooling fin assembly are connected, as the fan runs, the vibration generated will be directly transmitted to the cooling fin assembly, causing obvious vibration, noise, and easily damaging electronic devices connected to the radiator. Utility Model Content

[0006] Based on this, the utility model provides a fan shock-absorbing bracket, which uses the main frame, shock-absorbing blocks, and nuts to cooperate with each other, and adopts the method of serial connection and threaded connection. As long as the screw passes through the nut and is connected to the heat dissipation fin group, it can ensure that the heat dissipation fan will not loosen or deviate, with low operation difficulty and high reliability. At the same time, the shock-absorbing blocks are used to absorb and buffer the vibration generated by the operation of the heat dissipation fan, so as to achieve the purpose of weakening the vibration, reducing noise, and protecting electronic devices.

[0007] A fan shock absorbing bracket, comprising:

[0008] The main frame is used to accommodate the fan blades and the motor; a plurality of mounting parts are evenly distributed on the outer peripheral side of the main frame; each mounting part includes: a clamping column, a first connecting ring located at one end of the clamping column, and a second connecting ring located at the other end of the clamping column; the first connecting ring and the second connecting ring are parallel to each other; and

[0009] A shock-absorbing connector connected to the main frame; there are multiple shock-absorbing connectors and they are connected to the mounting parts one by one; each shock-absorbing connector includes: a shock-absorbing block clamped on the clamping column and a nut passed through the shock-absorbing block; the shock-absorbing block is an elastic rubber block, and the shock-absorbing block is provided with a first shock-absorbing portion wrapping the first connecting ring and a second shock-absorbing portion wrapping the second connecting ring; the nut is arranged parallel to the axial direction of the main frame; the nut is located between the first connecting ring and the second connecting ring, and the nut, the first connecting ring, and the second connecting ring are coaxial.

[0010] When assembling the above-mentioned fan shock-absorbing bracket, the nut is first inserted into the shock-absorbing block, and then the shock-absorbing block is laterally inserted into the mounting portion of the main frame. When in use, the screw is inserted into the first shock-absorbing portion, the first connecting ring, the nut, the second connecting ring, and the second shock-absorbing portion in sequence, and then connected to the heat dissipation fin group. Among them, the screw rod of the screw is connected to the screw hole on the heat dissipation fin group after passing through the first shock-absorbing portion, the first connecting ring, the second connecting ring, and the second shock-absorbing portion in sequence, and the screw rod of the screw is connected to the internal thread of the nut. The head of the screw abuts against the first shock-absorbing portion, and the heat dissipation fin group abuts against the second shock-absorbing portion. Therefore, when installing the heat dissipation fan, the first connecting ring, the nut, and the second connecting ring are connected in series in sequence by screws, and the internal thread of the nut is used to achieve radial and axial limiting, so that the screw and the nut are firmly connected, and then the screw is firmly connected to the main frame. When the heat dissipation fan is running, the vibration generated by it will be transmitted to the shock-absorbing block through the first shock-absorbing portion, the nut, and the second shock-absorbing portion. The shock absorber is an elastic rubber block that can absorb vibration energy, thereby reducing the vibration. Through the above design, the main frame, shock absorber, and nut cooperate with each other, and the serial and threaded connection method is adopted. As long as the screw passes through the nut and connects with the heat sink fin group, it can ensure that the cooling fan will not loosen or deviate. The operation is easy and the reliability is strong. At the same time, the shock absorber plays the role of absorbing energy and buffering the vibration generated by the operation of the cooling fan, so as to achieve the purpose of reducing the vibration, reducing noise, and protecting electronic devices.

[0011] In one embodiment, the clamping column includes: an axial clamping block and a radial clamping block radiating outward from the axial clamping block; the axial clamping block and the radial clamping block are both clamped on the inner side of the shock absorbing block. The axial clamping block and the radial clamping block are used to realize multi-axial clamping between the clamping column and the shock absorbing block, so that the connection between the two is more stable.

[0012] In one embodiment, the mounting portion is further provided with a first limiting portion arranged along the circumference of the main frame; the shock absorbing block is provided with a second limiting portion matching the first limiting portion. When the shock absorbing block is connected to the main frame, the first limiting portion and the second limiting portion can be used to accurately dock the shock absorbing block with the mounting portion, thereby improving the assembly accuracy and stability after assembly.

[0013] In one embodiment, the first limit portion is provided with latch teeth evenly distributed along the circumference of the main frame; the latch teeth abut against the inner side of the shock absorbing block. The latch teeth can increase the friction coefficient between the mounting portion and the inner side of the shock absorbing block, and enhance the connection stability between the shock absorbing block and the main frame.

[0014] In one embodiment, the end surfaces of the first shock absorbing part and the second shock absorbing part are both provided with anti-skid patterns, which can increase the friction coefficient between the screw and the shock absorbing block, and between the shock absorbing block and the heat dissipation fin group, thereby improving the installation stability of the heat dissipation fan.

[0015] In one embodiment, the first shock absorbing part is provided with a first slot for the first connecting ring to extend from the side; the second shock absorbing part is provided with a second slot for the second connecting ring to extend from the side. By utilizing the elasticity of the shock absorbing block, the first connecting ring and the second connecting ring are inserted into the shock absorbing block from the side, so as to wrap and protect the first connecting ring and the second connecting ring, thereby achieving a shock absorbing effect and reducing the difficulty of installation.

[0016] In one embodiment, the nut is a polygonal columnar structure. The nut with a polygonal columnar structure has a simple structure, and the polygonal structure can be used to limit the circumferential direction of the nut.

[0017] At the same time, the utility model also provides a heat dissipation fan.

[0019] The above-mentioned cooling fan is provided with a fan shock-absorbing bracket. The fan shock-absorbing bracket uses the main frame, the shock-absorbing block, and the nut to cooperate with each other, and adopts the method of serial connection and threaded connection. As long as the screw passes through the nut and is connected to the cooling fin group, it can ensure that the cooling fan will not loosen or deviate. The operation difficulty is low and the reliability is strong. At the same time, the shock-absorbing block is used to absorb and buffer the vibration generated by the operation of the cooling fan, so as to achieve the purpose of weakening the vibration, reducing noise, and protecting electronic devices.

[0050] like Figures 1 to 12 As shown, it is a fan shock absorbing bracket 100 according to an embodiment of the present invention.

[0051] like Figure 1 and Figure 2 As shown, the fan shock-absorbing bracket 100 includes: a main frame 10 and a shock-absorbing connector 20 connected to the main frame 10. The main frame 10 is used to install the blades and motor of the cooling fan, and the shock-absorbing connector 20 serves as a connecting medium between the screws, the main frame 10, and the cooling fin group, and plays a shock-absorbing effect.

[0052] Below, combined Figures 1 to 12 As shown, the above-mentioned fan shock absorbing bracket 100 is further explained.

[0053] like Figure 3 As shown, a plurality of mounting portions 11 are evenly distributed on the outer periphery of the main frame 10. Figures 1 to 3 ,as well as Figure 6 As shown, in this embodiment, the number of mounting portions 11 is four and they are arranged one by one at the four corners of the main frame 10. In other embodiments, the number of mounting portions 11 can also be two, three, five, or more, provided that the mounting portions 11 are evenly distributed. In this embodiment, the main frame 10 is an integrally formed insulating plastic frame body.

[0054] Combination Figure 3 and Figure 6 As shown, each mounting portion 11 includes: a clamping column 111, a first connecting ring 112 located at one end of the clamping column 111, and a second connecting ring 113 located at the other end of the clamping column 111. The first connecting ring 112 and the second connecting ring 113 are parallel to each other. Figure 3 As shown in the figure, in this embodiment, the first connecting ring 112 and the second connecting ring 113 are arranged in pairs, and a pair of the first connecting ring 112 and the second connecting ring 113 is arranged at each corner (four corners in total) of the main frame 10. When in use, the first connecting ring 112 and the second connecting ring 113 are both used for the screw portion of the screw to pass through, and the diameter of the inner hole thereof is slightly larger than the diameter of the screw portion of the screw.

[0055] Combination Figures 1 to 3 As shown, there are multiple damping connectors 20 and they are connected one-to-one with the mounting parts 11. For example, in this embodiment, there are four mounting parts 11, and accordingly, there are also four damping connectors 20.

[0056] like Figure 7 and Figure 8 As shown, each shock-absorbing connector 20 includes: a shock-absorbing block 21 clamped on the clamping column 111 and a nut 22 passing through the shock-absorbing block 21. Fig. 9 and Fig.10 As shown, the shock absorbing block 21 is an elastic rubber block, and the shock absorbing block 21 is provided with a first shock absorbing portion 211 wrapping the first connecting ring 112 and a second shock absorbing portion 212 wrapping the second connecting ring 113. Figure 4 As shown, the nut 22 is arranged parallel to the axial direction of the main frame 10. Figure 5 As shown, the nut 22 is located between the first connecting ring 112 and the second connecting ring 113, and the nut 22, the first connecting ring 112, and the second connecting ring 113 are coaxial, that is, the first connecting ring 112, the nut 22, and the second connecting ring 113 are coaxially arranged in sequence.

[0057] In this embodiment, the shock absorbing block 21 is preferably a silicone block, which has good elasticity, toughness, insulation, and corrosion resistance, and its heat-resistant temperature range is -60°C to 300°C, which can cover the operating temperature range of most cooling fans.

[0058] In order to facilitate installation, the shock-absorbing connecting member 20 can also be improved.

[0059] For example, Figure 8 As shown, referring to the arrows shown in the figure, in this embodiment, the first shock absorbing part 211 is provided with a first clamping groove 2111 for the first connecting ring 112 to extend from the side, and the second shock absorbing part 212 is provided with a second clamping groove 2121 for the second connecting ring 113 to extend from the side. By utilizing the elasticity of the shock absorbing block 21, the first connecting ring 112 and the second connecting ring 113 are inserted into the shock absorbing block 21 from the side, so as to realize the wrapping protection of the first connecting ring 112 and the second connecting ring 113, thereby achieving the shock absorbing effect and reducing the difficulty of installation.

[0060] For example, Fig.11 As shown, in this embodiment, the nut 22 is a polygonal columnar structure. The polygonal columnar structure of the nut 22 is simple in structure, and the polygonal structure can be used to limit the circumferential direction of the nut 22. This design can also facilitate the removal and replacement of the nut 22. If the internal thread of the nut 22 is loose, it can be quickly replaced.

[0061] In other embodiments, the nut 22 may also be a columnar structure of other shapes, such as a columnar structure with a convex structure or an irregular structure on the outer circumference, and the nut 22 is embedded in the shock absorbing block 21 by injection molding.

[0062] In order to improve the connection stability between the shock absorbing block 21 and the mounting portion 11 of the main frame 10 , the mounting portion 11 and / or the shock absorbing block 21 may be improved.

[0063] For example, Figure 6 As shown, in this embodiment, the clamping column 111 includes: an axial clamping block 1111 and a radial clamping block 1112 radiating outward from the axial clamping block 1111. The axial clamping block 1111 and the radial clamping block 1112 are both clamped on the inner side of the shock absorbing block 21. The axial clamping block 1111 and the radial clamping block 1112 are used to realize the multi-axial clamping between the clamping column 111 and the shock absorbing block 21, so that the connection between the two is more stable.

[0064] For example, Figure 6 As shown, in this embodiment, the mounting portion 11 is further provided with a first limiting portion 114 arranged along the circumference of the main frame 10. Figure 7 and Figure 8As shown, the shock absorbing block 21 is provided with a second limiting portion 213 matching the first limiting portion 114. When the shock absorbing block 21 is connected to the main frame 10, the first limiting portion 114 and the second limiting portion 213 can be used to accurately connect the shock absorbing block 21 with the mounting portion 11, thereby improving the assembly accuracy and stability after assembly.

[0065] Furthermore, if Figure 6 As shown, the first limiting portion 114 may be provided with latch teeth 1141 evenly distributed along the circumference of the main frame 10. The latch teeth 1141 abut against the inner side of the shock absorbing block 21. The latch teeth 1141 may increase the friction coefficient between the mounting portion 11 and the inner side of the shock absorbing block 21, and enhance the connection stability between the shock absorbing block 21 and the main frame 10.

[0066] Brief description of working principle:

[0067] When assembling, Figure 3 As shown, firstly, the nut 22 is inserted into the shock absorbing block 21, as shown in FIG. Figure 4 As shown, the shock absorbing block 21 is then laterally inserted into the mounting portion 11 of the main frame 10 .

[0068] When using, Fig.12 As shown, the screw 2000 sequentially penetrates the first damping part 211, the first connecting ring 112, the nut 22, the second connecting ring 113, and the second damping part 212, and then connects with the heat sink fin group 3000. The screw rod of the screw 2000 sequentially penetrates the first damping part 211, the first connecting ring 112, the second connecting ring 113, and the second damping part 212, and then connects with the screw hole on the heat sink fin group 3000, and the screw rod of the screw 2000 is connected with the internal thread of the nut 22. The head of the screw 2000 abuts against the first damping part 211, and the heat sink fin group 3000 abuts against the second damping part 212. Therefore, when installing the cooling fan, the first connecting ring 112, the nut 22, and the second connecting ring 113 are connected in series in sequence by the screw 2000, and the internal thread of the nut 22 is used to achieve radial and axial limiting, so that the screw 2000 is firmly connected to the nut 22, thereby realizing a firm connection between the screw 2000 and the main frame 10. When the cooling fan is running, the vibration generated by it will be transmitted to the shock absorbing block 21 through the first shock absorbing part 211, the nut 22, and the second shock absorbing part 212. The shock absorbing block 21 is an elastic rubber block that can absorb vibration energy, thereby weakening the vibration.

[0069] In order to improve the installation stability of the cooling fan, Figure 1 and Figure 2As shown, the end surfaces of the first damping part 211 and the second damping part 212 can be provided with anti-skid patterns 214. The anti-skid patterns 214 can increase the friction coefficient between the screw 2000 and the damping block 21, and between the damping block 21 and the heat sink fin group 3000, thereby improving the installation stability of the heat sink fan.

[0070] The fan shock-absorbing bracket 100 uses the main frame 10, the shock-absorbing block 21, and the nut 22 to cooperate with each other, and adopts the serial connection and threaded connection method. As long as the screw passes through the nut 22 and is connected to the heat dissipation fin group, it can ensure that the heat dissipation fan will not be loosened or offset, with low operation difficulty and high reliability. At the same time, the shock-absorbing block 21 plays the role of energy absorption and buffering for the vibration generated by the operation of the heat dissipation fan, so as to achieve the purpose of weakening the vibration, reducing noise, and protecting electronic devices.

[0071] like Figures 13 to 15 As shown, it is a heat dissipation fan 1000 according to an embodiment of the present invention.

[0072] like Fig.13 and Fig.14 As shown, the heat dissipation fan 100 comprises: a fan vibration reduction bracket 100, a fan blade 200, and a motor 300 connected to the fan blade 200. The fan blade 200 and the motor 300 are both mounted on the fan vibration reduction bracket 100.

[0073] For the description of the fan shock absorbing bracket 100 , please refer to the above text and will not be repeated here.

[0074] like Fig.15 As shown, the motor 300 is mounted on the main frame 10, and the fan blades 200 and the motor 300 are both accommodated in the main frame 10. During operation, the motor 300 drives the fan blades 200 to rotate to form an airflow required to accelerate heat dissipation.

[0075] The above-mentioned cooling fan 1000 is provided with a fan shock-absorbing bracket 100. The fan shock-absorbing bracket 100 uses the main frame 10, the shock-absorbing block 21, and the nut 22 to cooperate with each other, and adopts the method of serial connection and threaded connection. As long as the screw passes through the nut 22 and is connected to the cooling fin group, it can ensure that the cooling fan 1000 will not be loosened or offset, with low operation difficulty and high reliability. At the same time, the shock-absorbing block 21 plays the role of energy absorption and buffering for the vibration generated by the operation of the cooling fan 1000, so as to achieve the purpose of weakening the vibration, reducing noise, and protecting electronic devices.

[0076] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0077] The above embodiments only express the preferred implementation of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
