Description

Technical Field

[0001] The utility model relates to the technical field of fans, in particular to a vibration reduction structure of a fan. Background Art

[0002] This section merely provides background information related to the present disclosure and is not necessarily prior art.

[0003] Turbine fans are more and more widely used because of their small size, light weight, and high efficiency. The efficiency and noise of a fan are positively correlated. When the efficiency of the fan is guaranteed, its own noise is relatively certain, so some noise reduction measures need to be taken from a structural perspective. Currently, most fans on the market are fixed by directly pressing the fan with a plastic bracket, and then fixing the bracket to the base with screws or directly fixing the fan casing with screws. In this way, the fixation of the fan casing to the bracket or to the base relies on the hard contact between plastic parts, and therefore does not play a vibration reduction role. When the fan is running at high speed, the vibration of the fan itself will be transmitted to the parts in contact with it, causing resonance of the bracket or base, thereby generating vibration noise and reducing the user's comfort and experience.

[0037] like Figures 1 to 6 As shown, according to the implementation mode of the utility model, the first aspect of the utility model proposes a fan vibration reduction structure, the fan vibration reduction structure includes a fixed base 10, a fixed bracket 20 and an elastic vibration reduction assembly 30, the fixed bracket 20 is arranged opposite to the fixed base 10, and an accommodating space for accommodating a fan 40 is formed between the fixed base 10 and the fixed bracket 20, the fixed bracket 20 is connected to the fixed base 10 through the elastic vibration reduction assembly 30, and at least a part of the elastic vibration reduction assembly 30 is clamped between the fan 40 and the fixed bracket 20.

[0038] It is understandable that the fixed base 10 can be a disc-shaped structure, and holes can be set on the fixed base 10 to cooperate with the protruding part on the fan 40 housing to achieve snap-on connection. An elastic pad can also be set between the fixed base 10 and the fan 40 housing to reduce the noise generated by the vibration of the fan 40 at the connection. The fixed bracket 20 can be set on the side of the fan 40 away from the fixed base 10. The fixed bracket 20 is connected to the fixed base 10 through an elastic vibration reduction component 30. The elastic vibration reduction component 30 can be a rubber part or a silicone part, which is made by an injection molding process. The elastic vibration reduction component 30 can be connected to the corresponding connection part of the fixed base 10 by bolt fixing, snap-on connection or sleeve connection.

In addition, part of the elastic vibration reduction component 30 is clamped between the fan 40 and the fixed bracket 20, so that the fixed base 10 and the fixed bracket 20 on both sides of the fan 40 are fixed and pressed, and the elastic vibration reduction component 30 is arranged at the connection between the fan 40 and the fixed bracket 20 to absorb the vibration there, thereby reducing the noise generated by the operation of the fan 40, thereby improving the user's experience when using the cleaning equipment. Specifically, the fan vibration reduction structure of the utility model can be used to install the fan of the cleaning equipment, such as the fan 40 of the sweeping robot or the sweeping and mopping integrated robot.

[0039] The utility model fixes the fan 40 through the fixed base 10, and connects the fixed bracket 20 to the fixed base 10 through the elastic vibration damping component 30. The elastic vibration damping component 30 can absorb the vibration of the fixed bracket 20 and the fixed base 10 when the fan 40 is running, and part of the elastic vibration damping component 30 is clamped between the fan 40 and the fixed bracket 20, so that the fan 40 is clamped between the elastic vibration damping component 30 and the fixed base 10, so that the elastic vibration damping component 30 can absorb the vibration generated by the operation of the fan 40, thereby reducing the noise generated by the operation of the fan 40 and improving the user experience.

[0040] In some embodiments of the utility model, the fan vibration reduction structure also includes a support platform 11 and a fastener 12. The support platform 11 is arranged on the base body. The support platform 11 extends along the axial direction of the fan 40. The support platform 11 is provided with a first through hole 111. The elastic vibration reduction assembly 30 is provided with a second through hole 31. The fastener 12 is passed through the first through hole 111 and the second through hole 31. The fastener 12 is used to fix the elastic vibration reduction assembly 30 on the support platform 11.

[0041] It can be understood that the elastic vibration reduction assembly 30 is fixed to the support platform 11 by the fastener 12 to achieve connection with the base body. The support platform 11 is arranged on the side where the base body is connected to the fan 40. The support platform 11 can be integrally formed with the base body. The support platform 11 can be a prismatic or cylindrical structure. The extension direction of the support platform 11 can be arranged parallel to the axial direction of the fan 40. A first through hole 111 is provided at one end of the support platform 11 away from the base body. A second through hole 31 is provided on the elastic vibration reduction component 30. The first through hole 111 and the second through hole 31 can be circular holes or threaded holes. The fastener 12 can be a pin or a screw, which is connected to the first through hole 111 by plugging or screwing, and is penetrated in the second through hole 31. At this time, the elastic vibration reduction component 30 is fixed to the support platform 11 by the fastener 12, and the elastic vibration reduction component 30 is also connected to the fixed bracket 20, so that the fixed bracket 20 is connected to the support platform 11 through the elastic vibration reduction component 30. The connection between the two is an elastic member, which can absorb the vibration generated by the fan 40, thereby reducing the noise of the fan 40 and improving the user experience.

[0042] In some embodiments of the utility model, the support platform 11 includes a platform body 112 and a reinforcing rib 113. Along the axial direction of the fan 40, the first end of the platform body 112 is connected to the fixed base 10, and the second end of the platform body 112 is penetrated through the second through hole 31. The reinforcing rib 113 is arranged on the outer peripheral wall of the platform body 112 and is spaced from the second end of the platform body 112. The second end of the platform body 112 is provided with a first through hole 111. The fastener 12 includes a coaxially connected clamping portion 121 and a through hole 122. The through hole 122 is penetrated through the first through hole 111 and the second through hole 31. Part of the elastic vibration damping assembly 30 is clamped between the clamping portion 121 and the reinforcing rib 113.

[0043] It can be understood that the platform 112 can be prismatic or cylindrical, and the reinforcing ribs 113 are arranged on the outer peripheral wall of the platform 112. The reinforcing ribs 113 can be integrally formed with the platform 112, and the reinforcing ribs 113 can extend along the axial direction of the platform 112. Multiple reinforcing ribs 113 can be arranged at circumferential intervals along the platform 112. The length of the reinforcing ribs 113 extending along the axial direction of the platform 112 is less than the axial length of the platform 112, so that one end of the platform 112 forms a groove structure, and the groove structure can accommodate part of the elastic vibration damping assembly 30. A first through hole 111 may be provided at one end of the platform 112 away from the fixed base 10, and at the same time, the end of the platform 112 away from the fixed base 10 is penetrated in the second through hole 31 of the elastic vibration damping assembly 30. The fastener 12 may be a screw or a pin structure, including a clamping portion 121 with a larger diameter and a through hole 122 with a smaller diameter. The through hole 122 is penetrated in the first through hole 111, and part of the elastic vibration damping assembly 30 is clamped between the clamping portion 121 and the platform 112 by the clamping portion 121, so that the reliability of the connection between the elastic vibration damping assembly 30 and the platform 112 is enhanced, and the phenomenon of accidental displacement of the elastic vibration damping assembly 30 when the fan 40 vibrates is reduced.

[0044] In some embodiments of the utility model, the fixing bracket 20 includes an assembly fork 21 and a cover body 22, the assembly fork 21 is connected to the outer peripheral wall of the cover body 22, the assembly fork 21 is provided with a notch 211 or a through hole, and the elastic vibration reduction assembly 30 includes a sleeve 32, a limit platform 33 and a first buffer platform 34, all of which are flexible structures, and the flexible structure can be a rubber part or a silicone part. The sleeve 32 defines a second through hole 31, the platform 112 is penetrated in the second through hole 31, the sleeve 32 is penetrated in the notch 211 or the through hole, along the axial direction of the fan 40, the first end of the sleeve 32 abuts against the reinforcing rib 113, the limit platform 33 is arranged on the outer peripheral wall of the second end of the sleeve 32, the first buffer platform 34 is arranged on the inner peripheral wall of the second end of the sleeve 32, and the first buffer platform 34 is clamped between the pressing portion 121 and the platform 112.

[0045] It can be understood that the assembly fork 21 is a fork-shaped structure, the outer shape of the cover body 22 is adapted to the side of the fan 40 away from the fixed base 10, the cover body 22 can be a cylindrical structure with one end closed, and is spaced apart from one side of the fan 40, and the cover body 22 can protect the fan 40 from damage. The assembly fork 21 extends along the radial direction of the cover body 22, and one end of the assembly fork 21 is connected to the cover body 22, which can be an integrally formed connection. A notch 211 is provided at one end of the assembly fork 21 away from the cover body 22, and the outer shape of the notch 211 is adapted to the sleeve 32, and can be an arc-shaped or polygonal notch 211. The end of the elastic vibration damping component 30 connected to the support platform 11 includes a sleeve 32, a limit platform 33 and a first buffer platform 34. The sleeve 32 can be cylindrical or prismatic. The sleeve 32 defines a second through-hole 31. The limit platform 33 is arranged in the cylinder cavity formed by the sleeve 32, and the limit platform 33 is arranged at one end of the sleeve 32 away from the reinforcing rib 113. The first buffer platform 34 is provided on the circumferential outer side of the limit platform 33, that is, on the outer surface of the sleeve 32. The limit platform 33 and the first buffer platform 34 can be arranged in an annular structure extending along the circumference of the sleeve 32. The sleeve 32, the limit platform 33 and the first buffer platform 34 can be integrally formed. When installing the elastic vibration damping assembly 30, first, the assembly fork 21 is plugged into the sleeve 32, and then the sleeve 32 is sleeved on the platform 112, and then the axial position of the sleeve 32 is adjusted to abut against the reinforcing rib 113. At this time, the limit platform 33 abuts against one axial end of the platform 112, and then the limit member is sequentially inserted into the second through hole 31 and the first through hole 111, so that the limit member fixes the elastic vibration damping assembly 30 on the platform 112. At this time, the clamping portion 121 of the limit member presses the first buffer platform 34, so that the connection reliability of the elastic vibration damping assembly 30 is enhanced.

[0046] In some embodiments of the utility model, the number of assembly forks 21, the number of support platforms 11 and the number of fasteners 12 are all multiple. Along the circumferential direction of the fan 40, all assembly forks 21 are arranged at intervals on the outer peripheral wall of the cover body 22, and all support platforms 11 are arranged at intervals on the outer peripheral side of the fan 40, and the position of the support platform 11 corresponds to the position of the assembly fork 21.

[0047] It is understandable that in order to enhance the reliability of the installation of the fan 40, the fan 40 is fixed by setting a plurality of assembly forks 21, elastic vibration damping components 30 and support platforms 11. Specifically, the stability of the fan 40 is improved by fixing multiple positions on the circumference of the fan 40. Multiple assembly forks 21 can be set along the circumference of the cover 22, and multiple support platforms 11 are set on the fixed base 10 at positions corresponding to the assembly forks 21 for fixing the assembly forks 21. The assembly forks 21 are connected to the support platforms 11 through the elastic vibration damping components 30, and the connection is reinforced by fasteners 12. The fan 40 is pressed against the fixed base 10 by the radially distributed multiple assembly forks 21 and the matching elastic vibration damping components 30. The installation stability of the fan 40 is improved, and the elastic vibration damping components 30 are used to absorb vibrations at multiple positions of the fan 40, reduce noise generation, and improve user experience.

[0048] In some embodiments of the utility model, the elastic vibration damping assembly 30 also includes a second buffer platform 35 with a flexible structure, the second buffer platform 35 is connected to the outer peripheral wall of the sleeve 32, the second buffer platform 35 is spaced apart from the limit platform 33, and the second buffer platform 35 is clamped between the assembly fork 21 and the fan 40.

[0049] It is understandable that the second buffer platform 35 can be a plate-type structure. Since the second buffer platform 35 is arranged between the volute part 42 of the fan 40 and the assembly fork 21 to absorb the vibration of the volute part 42 when the fan 40 is running, the shape of the second buffer platform 35 is adapted to the assembly fork 21 and is a plate-type structure for easy installation. The second buffer platform 35 can be integrally connected with the sleeve 32. The second buffer platform 35 is arranged at intervals with the limit platform 33, so that a groove is formed between the second buffer platform 35 and the limit platform 33. After the notch 211 of the assembly fork 21 is connected with the sleeve 32, the assembly fork 21 is located in the groove to limit the assembly fork 21 along the axial direction of the fan 40, thereby improving the reliability of the connection. In addition, the assembly fork 21 has elastic vibration reduction components 30 on both sides of the upper and lower sides of the connection with the sleeve 32 along the axial direction of the fan 40 to abut against each other, which can absorb vibration and reduce the noise generated by the hard connection at the connection.

[0050] In some embodiments of the present invention, the elastic vibration reduction assembly 30 further includes a positioning column 36 disposed on the second buffer platform 35 . The positioning column 36 is a flexible structure. A positioning hole 212 is provided on the assembly fork 21 . The positioning column 36 passes through the positioning hole 212 .

[0051] It is understandable that the second buffer platform 35 is provided with a positioning column 36, and the positioning column 36 can be integrally formed with the second buffer platform 35. The positioning column 36 can be cylindrical or prismatic, and an annular protrusion can also be provided on the positioning column 36, and the annular protrusion extends along the circumference of the positioning column 36. The assembly fork 21 is provided with a positioning hole 212 that is compatible with the positioning column 36. After the notch 211 of the assembly fork 21 is connected to the sleeve 32, the positioning column 36 is inserted into the positioning hole 212 to further strengthen the connection and improve the reliability of the connection. In addition, the annular protrusion on the positioning column 36 can also limit the assembly fork 21, so that the assembly fork 21 is limited between the annular protrusion and the second buffer portion, further improving the reliability of the connection.

[0052] In some embodiments of the present invention, the fan 40 includes a driving part 41 and a volute part 42, the driving part 41 is arranged at one axial end of the volute part 42, the cover body 22 is covered on the driving part 41, and the second buffer platform 35 is clamped between the assembly fork 21 and the volute part 42.

[0053] It is understandable that the driving part 41 of the fan 40 can be an electrode, and the interior of the volute part 42 forms the impeller mounting chamber of the fan 40 and the flow channel of the fan 40. The driving part 41 is installed at one axial end of the volute part 42 and is connected to the impeller through a transmission shaft, and an air inlet is provided at the other axial end of the volute part 42. The cover body 22 is provided on the outside of the driving part 41 to protect the driving part 41 from external damage. The second buffer table 35 is clamped between the assembly fork 21 and the volute part 42, so that after the volute part 42 is assembled to the first mounting hole, the other side of the volute part 42 is pressed by the assembly fork 21 to fix the fan 40, and the second buffer table 35 is clamped at the connection to absorb the vibration of the volute part 42 when the fan 40 is running, so as to reduce the noise of the fan 40 and improve the user experience.

[0054] In some embodiments of the present invention, the fan vibration reduction structure further includes a vibration reduction pad 50 , and the vibration reduction pad 50 is sandwiched between the fixed base 10 and the fan 40 .

[0055] It is understandable that a hole can be set on the side where the fixed base 10 is connected to the fan 40, and the hole cooperates with the protruding part of the fan 40 to achieve the installation and fixation of the fan 40. A vibration-damping pad 50 can be set at the hole. The vibration-damping pad 50 can be a rubber pad or a silicone pad or a sponge pad. The elastic material absorbs the vibration at this place to avoid the hard connection between the fan 40 and the fixed base 10, and reduce the noise generated when the fan 40 is running. Specifically, an anti-skid rib structure is also provided on both sides of the vibration-damping pad 50 connected to the fan 40 and / or the fixed base 10. The anti-skid rib structure can be in a grid shape and protrude from the outer surface of the vibration-damping pad 50, thereby increasing the friction between the vibration-damping pad 50 and the fan 40 and the fixed base 10, reducing the phenomenon of accidental sliding of the vibration-damping pad 50, and improving reliability.

[0056] In some embodiments of the utility model, the fixed base 10 is provided with a first mounting hole, the vibration damping pad 50 is provided with a second mounting hole, the second mounting hole is coaxially arranged with the first mounting hole, and along the axial direction of the fan 40, the first end of the fan 40 is provided with an air inlet 43, and the first end of the fan 40 is installed in the second mounting hole.

[0057] It can be understood that a first mounting hole is provided on the fixed base 10 and passes through it, and an air inlet 43 is provided at one end of the fan 40 along its own axial direction. The outer peripheral side of the air inlet 43 is the outer shell of the fan 40, which is located in the first mounting hole, and a vibration-damping pad 50 is clamped between the first end of the fan 40 and the fixed base 10. The vibration-damping pad 50 has a second mounting hole, so that the first end of the fan 40 can be connected to the second mounting hole. The elastic material of the vibration-damping pad 50 absorbs the vibration of the air inlet 43 of the fan 40, avoids the fan 40 and the fixed base 10 from being hard-connected, and reduces the noise generated when the fan 40 is running.

[0058] In some embodiments of the present invention, the elastic vibration reduction assembly 30 is an integrally formed structure.

[0059] It is understandable that the elastic vibration damping component 30 can be manufactured by integral injection molding, such as an integral injection molded rubber part or silicone part, to reduce the connection gap and improve the reliability and durability of the elastic vibration damping component 30.

[0060] The above are only preferred specific implementations of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model shall be based on the protection scope of the claims.
