Description

Technical Field

[0001] This application relates to the field of electronic equipment technology, and more particularly to a cooling fan and electronic equipment. Background Technology

[0002] With the miniaturization of electronic devices, the gap between the cooling fan and the device housing is gradually decreasing.

[0003] When the equipment casing is deformed by external force, it is easy for the equipment casing to come into contact with the fan casing of the cooling fan, which will cause the fan casing to deform and thus cause the fan casing to come into contact with the fan blades of the cooling fan, producing abnormal noise. Utility Model Content

[0004] This application provides a cooling fan and an electronic device to prevent abnormal noise caused by contact between the fan housing and the fan blades.

[0005] In a first aspect, embodiments of this application provide a cooling fan and an electronic device, including:

[0006] Fan housing, with a receiving cavity inside, is used for mounting inside the component to be cooled;

[0007] Fan blades, the fan blades are rotated and disposed within the receiving cavity;

[0008] At least one support member is inserted into the fan housing, with both ends of the support member located outside the fan housing and respectively used to contact the two inner walls opposite to the component to be cooled.

[0009] In one possible implementation, the fan housing includes:

[0010] Fan base housing, with the receiving cavity located inside the fan base housing;

[0011] The fan cover is placed on the bottom of the fan and seals the receiving cavity;

[0012] The fan base has at least one first mounting hole, and the fan cover has at least one second mounting hole corresponding to the first mounting hole. The support member is inserted into the fan base and the fan cover in sequence through the first mounting hole and the second mounting hole.

[0013] In one possible implementation, the support member has a first abutting portion and a second abutting portion, which are arranged at intervals along the extending direction of the support member.

[0014] The first abutting part abuts against the outer surface of the fan base, and the second abutting part abuts against the inner surface of the fan cover.

[0015] In one possible implementation, the support member is a stepped column, which includes a first support part, a second support part, and a third support part arranged sequentially. The diameter of the first support part is smaller than the diameter of the second support part, and the diameter of the second support part is smaller than the diameter of the third support part.

[0016] Both the third support and the first support are located outside the fan housing;

[0017] The part of the second support that is away from the third support abuts against the inner surface of the fan cover;

[0018] The end of the third support unit facing the second support unit abuts against the outer surface of the fan base.

[0019] In one possible implementation, the second support portion is frustum-shaped, with its smaller diameter end connected to the first support portion and its larger diameter end connected to the third support portion.

[0020] In one possible implementation, the cooling fan further includes at least one protective element disposed between the support and the component to be cooled.

[0021] In one possible implementation, the protective member has an abutment groove, and a portion of the support member is located within the abutment groove.

[0022] In one possible implementation, the protective element is a cushioning pad.

[0023] Secondly, embodiments of this application provide an electronic device, including a device housing and any of the cooling fans provided in the first aspect disposed within the device housing.

[0024] In one possible implementation, the device housing includes a rear cover and a support frame, the rear cover and the support frame being disposed opposite to each other:

[0025] The two ends of the support component in the cooling fan contact the inner wall of the back cover and the inner wall of the support frame, respectively.

[0026] The cooling fan and electronic device provided in this application embodiment have at least one support member. The two ends of the support member are respectively used to contact the two inner walls of the component to be cooled. When an external force is applied to the component to be cooled near the support member, the support member can bear most of the external force to reduce the deformation of the component to be cooled. By inserting the support member into the fan housing, both ends of the support member are located outside the fan housing. The deformation of the component to be cooled is reduced when subjected to force, and the contact between the fan housing and the component to be cooled can be avoided, thus preventing deformation of the fan housing. Furthermore, the fan blades are rotatably disposed in the receiving cavity of the fan housing. The fan housing does not deform, thus preventing contact between the fan housing and the fan blades and preventing abnormal noise. Attached Figure Description

Detailed Implementation

[0040] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0041] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. In the description of the embodiments of this application, it should be understood that the terms "center," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships (if present), are based on the orientation or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the embodiments of this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the embodiments of this application. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element. Where there is no conflict, embodiments of this application and the various features thereof can be combined with each other, all of which are within the scope of protection of this application.

[0042] This application provides an electronic device. Figure 1 An exploded view of a portion of the structure of an electronic device provided in an embodiment of this application; Figure 2 This is a partial structural diagram of the internal structure of an electronic device provided in an embodiment of this application.

[0043] Specifically, the electronic device includes a heat-dissipating component and a cooling fan disposed within the heat-dissipating component.

[0044] Cooling fans can provide air cooling for components to be cooled, ensuring that the components operate in a suitable environment and thus maintain good performance.

[0045] In some embodiments, please refer to Figure 1 and Figure 2 The components to be cooled include the device housing 20 and the heating element (not shown in the figure). Both the heating element and the cooling fan 10 are disposed inside the device housing 20, and the cooling fan 10 is located on one side of the heating element.

[0046] The housing 20 provides containment and protection for the heating element, preventing external interference with its operation. However, the relatively enclosed space of the housing 20 makes it difficult for the heat generated by the heating element to dissipate.

[0047] In this embodiment, by placing the cooling fan 10 on one side of the heat-generating element, heat dissipation can be applied to the heat-generating parts of the heat-generating element to ensure its normal operation.

[0048] Further, please refer to Figure 1 and Figure 2 The device housing 20 includes a rear cover 21 and a support frame 22, which are arranged opposite to each other. The heating element is located on the side of the support frame 22 facing the rear cover 21, and the cooling fan 10 is located on the side of the heating element facing the rear cover 21.

[0049] In this embodiment, the support frame 22 provides a support base for the heating element and the cooling fan 10. The sequential arrangement of the support frame 22, the heating element, the cooling fan 10 and the back cover 21 also creates conditions for the miniaturization of electronic devices.

[0050] Understandable, Figure 1 and Figure 2 The diagram only schematically illustrates some of the components included in the electronic device; the actual shape, size, location, and construction of these components are not subject to change. Figure 1 and Figure 2 Due to limitations, electronic devices can also include, compared to Figure 1 and Figure 2 More or fewer parts.

[0051] It should be noted that this application embodiment does not limit the specific type of electronic device. For example, the electronic device can be a laptop, smartphone, gaming device, or other portable electronic product. This application embodiment does not limit the specific type of support frame 22. For example, the support frame 22 can be a keyboard support frame 22 or a screen support frame 22.

[0052] With the miniaturization of electronic devices, the gap between the cooling fan and the device housing of electronic devices is gradually decreasing.

[0053] When the equipment casing is deformed by external force, it is easy for the equipment casing to come into contact with the fan casing of the cooling fan, which will cause the fan casing to deform. This will cause the fan casing to come into contact with the fan blades of the cooling fan, producing abnormal noise, or even damaging the fan blades.

[0054] For the above technical issues, please refer to [link / reference]. Figure 1 and Figure 2This application provides a cooling fan, including: a fan housing 100, the fan housing 100 having a receiving cavity 110, the fan housing 100 being used to install inside a component to be cooled; fan blades 200, the fan blades 200 being rotatably disposed within the receiving cavity 110; and at least one support member 300, the support member 300 being inserted into the fan housing 100, both ends of the support member 300 being located outside the fan housing 100, and respectively being used to contact two inner walls opposite to the component to be cooled.

[0055] The cooling fan 10 provided in this application embodiment has at least one support member 300. The two ends of the support member 300 are respectively used to contact the two inner walls opposite to the heat dissipation component. When an external force is applied to the heat dissipation component near the support member 300, the support member 300 can withstand most of the external force, thereby reducing the deformation of the heat dissipation component.

[0056] By inserting the support member 300 onto the fan housing 100, with both ends of the support member 300 located outside the fan housing 100, the deformation of the heat-dissipating component under stress is reduced, thus preventing the fan housing 100 from contacting the heat-dissipating component and preventing deformation of the fan housing 100.

[0057] Furthermore, the fan blade 200 is rotatably disposed within the receiving cavity 110 of the fan housing 100, and the fan housing 100 does not deform, which can prevent the fan housing 100 from contacting the fan blade 200, thus preventing abnormal noise and preventing the fan blade 200 from being damaged due to collision with the fan housing 100.

[0058] It should be noted that the rotatable connection between the fan blade 200 and the fan housing 100 is a structural design known in the art and will not be described in detail here.

[0059] The preferred technical solution of the cooling fan 10 of this application embodiment is described below with reference to the accompanying drawings. Figure 3 A schematic diagram showing the connection between the support member 300 and the fan base 120; Figure 4 This is a structural schematic diagram of protective component 400.

[0060] For some specific implementation methods, please refer to Figure 1 and Figure 2 The component to be cooled includes a housing 20 and a heat-generating element disposed within the housing 20. A cooling fan 10 is disposed within the housing 20 and is used to dissipate heat from the heat-generating element.

[0061] The two ends of the support member 300 are respectively used to contact the two inner walls opposite to the equipment housing 20, so as to reduce the deformation of the equipment housing 20 under the action of external force, thereby avoiding abnormal noise caused by the contact between the fan blade 200 and the fan housing 100.

[0062] For further information, please refer to [link / reference]. Figure 1 and Figure 2 The equipment housing 20 includes a rear cover 21 and a support frame 22, which are arranged opposite to each other: the two ends of the support member 300 in the cooling fan 10 are in contact with the inner wall of the rear cover 21 and the inner wall of the support frame 22, respectively.

[0063] The back cover 21 and the support frame 22 are located in the external environment. By contacting the two ends of the support member 300 in the cooling fan 10 with the inner wall of the back cover 21 and the inner wall of the support frame 22 respectively, the back cover 21, the support member 300 and the support frame 22 together form a rigid structure. When an external force is applied to at least one of the back cover 21 and the support frame 22, the external force can be transmitted to the support member 300 through the back cover 21 or the support frame 22, and the support member 300 bears part of the external force. The back cover 21 and the support frame 22 are not easily deformed.

[0064] Based on this, the support member 300 is inserted into the fan housing 100, and both ends of the support member 300 are located outside the fan housing 100. The rear cover 21 and the support frame 22 will not contact the fan housing 100, thereby preventing the fan housing 100 from deforming.

[0065] It should be noted that the inner wall of the back cover 21 can be the inside of the support frame 22 facing the back cover 21, and the inner wall of the support frame 22 can be the inside of the support facing the back cover 21.

[0066] In some embodiments, please continue reading Figure 1 and Figure 2 The fan housing 100 includes: a fan base 120, with a receiving cavity 110 located inside the fan base 120; a fan cover 130, which covers the fan base 120 and closes the receiving cavity 110; the fan base 120 has at least one first mounting hole (not shown in the figure), and the fan cover 130 has at least one second mounting hole 140 corresponding to the first mounting hole; the support member 300 is inserted into the fan base 120 and the fan cover 130 in sequence through the first mounting hole and the second mounting hole 140.

[0067] In this embodiment, by providing a fan cover 130, which covers the fan base 120 and seals the receiving cavity 110 at the top of the fan base 120, a stable airflow channel can be formed within the fan housing 100. Furthermore, the fan base 120 and the fan cover 130 together form an air outlet 150 communicating with the receiving cavity 110, which facilitates heat dissipation.

[0068] Furthermore, the fan cover 130 and the fan base 120 can provide physical protection for the fan blades 200, effectively preventing external debris from interfering with the normal operation of the fan blades 200.

[0069] For some specific implementation methods, please refer to Figure 2 and Figure 3 The support member 300 has a first abutting part 310 and abutting part 320, and the first abutting part 310 and the second abutting part 320 are arranged alternately along the extending direction of the support member 300; the first abutting part 310 abuts against the outer surface of the fan bottom shell 120, and the second abutting part 320 abuts against the inner surface of the fan cover 130.

[0070] In this embodiment, by providing a first abutting part 310 and a second abutting part 320 on the support member 300, the first abutting part 310 abuts against the outer surface of the fan base 120 and the second abutting part 320 abuts against the inner surface of the fan cover 130, so that the heat dissipation component can simultaneously abut against and support the fan base 120 and the fan cover 130, ensuring the stability of the connection between the cooling fan 10 and the heat dissipation component.

[0071] Furthermore, by providing a first abutment portion 310 and abutment portion 320 on the support member 300, the support member 300 can perform both functions of maintaining the structural strength of the heat dissipation component and supporting the fan housing 100, eliminating the need to provide separate support components to support the fan housing 100, thereby improving the miniaturization of electronic devices.

[0072] It should be noted that this embodiment does not limit the specific types of the first abutment portion 310 and the second abutment portion 320, as long as they can stably support the fan base 120 and the fan cover 130. For example, both the first abutment portion 310 and the second abutment portion 320 can be support rings with stepped surfaces or protrusions.

[0073] Further, please refer to Figure 1 At least one support member 300 is provided inside the air outlet 150.

[0074] At the air outlet 150, the fan cover 130 and the fan base 120 are not connected, resulting in poor structural strength for both. This embodiment improves the structural strength of the fan cover 130 and the fan base 120 by providing at least one support member 300 within the air outlet 150. The first abutting portion 310 of the support member 300 abuts against the outer surface of the fan base 120, and the second abutting portion 320 abuts against the inner surface of the fan cover 130.

[0075] In other embodiments, please refer to Figure 2 and Figure 3The support member 300 is a stepped column, which includes a first support portion 330, a second support portion 340 and a third support portion 350 arranged sequentially. The diameter of the first support portion 330 is smaller than the diameter of the second support portion 340, and the diameter of the second support portion 340 is smaller than the diameter of the third support portion 350. The third support portion 350 and the first support portion 330 are both located outside the fan housing 100. The part of the second support portion 340 facing away from the third support portion 350 abuts against the inner surface of the fan cover 130. The part of the third support portion 350 facing the second support portion 340 abuts against the outer surface of the fan bottom housing 120.

[0076] In this embodiment, by setting the support member 300 as a stepped column, the diameters of the first support portion 330, the second support portion 340, and the third support portion 350 of the stepped column gradually increase, thereby achieving a multi-level support function. Furthermore, the stepped column structure is simple and easy to manufacture.

[0077] For some specific implementation methods, please refer to Figure 3 The second support portion 340 is frustum-shaped, with its small diameter end connected to the first support portion 330 and its large diameter end connected to the third support portion 350.

[0078] In this embodiment, by setting the second support portion 340 as a frustum, the small-diameter end of the second support portion 340 is connected to the first support portion 330, the diameter of the first support portion 330 is smaller than the diameter of the second support portion 340, and the diameter of the small-diameter end of the second support portion 340 and the diameter of the first support portion 330 are both set to be smaller than the diameter of the first connecting hole and the diameter of the second connecting hole, it is convenient for the support member 300 to be inserted into the fan housing 100. This not only reduces the installation difficulty of the support member 300, but also reduces the damage to the fan housing 100 caused by the support member 300 during the installation process.

[0079] As the diameter of the frustum-shaped second support portion 340 gradually increases from the small diameter end to the large diameter end, when the support member 300 is gradually inserted into the fan housing 100 from the fan base 120 toward the fan cover 130, the fit between the second support portion 340 and the fan base 120 can be gradually increased, making the connection between the support member 300 and the fan base 120 tighter, thereby ensuring the stability of the connection between the support member 300 and the fan housing 100.

[0080] In some other embodiments, please refer to Figure 1 and Figure 2 The cooling fan 10 also includes at least one protective component 400, which is disposed between the support 300 and the component to be cooled.

[0081] In this embodiment, by providing a protective component 400, which is positioned between the support component 300 and the component to be cooled, deformation of the component to be cooled due to insufficient force area can be avoided; friction between the two can also be avoided, thereby preventing abnormal noise or wear of the support component 300 or the component to be cooled.

[0082] It should be noted that this embodiment does not limit the specific arrangement of the protective component 400. For example, the protective component 400 is bonded to the heat dissipation component, or the protective component 400 is clamped between the support component 300 and the heat dissipation component.

[0083] In some specific implementations, the protective component 400 is a buffer pad.

[0084] In this embodiment, by setting the protective member 400 as a buffer pad, the protective member 400 can not only prevent the support member 300 from rubbing against the heat dissipation component, but also adaptably fill the gap between the support member 300 and the inner wall of the heat dissipation component, preventing the two from loosening.

[0085] For other specific implementations, please refer to Figure 1 , Figure 2 and Figure 4 The protective member 400 has an abutment groove 410, and a portion of the support member 300 is located within the abutment groove 410.

[0086] In this embodiment, by providing an abutment groove 410, a portion of the support member 300 is located within the abutment groove 410. The support member 300 can restrict the movement of the protective member 400 to prevent the protective member 400 from detaching from the support member 300, thereby ensuring the stability of the connection between the support member 300 and the heat dissipation component.

[0087] It should be understood that the embodiments of this application are not limited to the precise structures described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of this application is limited only by the appended claims.
