[0030] The embodiment of the present application provides a fan, Figure 1 is an overall schematic diagram of an implementation method of a fan in an embodiment of the present application, Figure 2 It is an overall schematic diagram of another implementation manner of the fan of the embodiment of the present application.

[0031] like Figure 1 and Figure 2 As shown, the fan 100 includes an impeller 1, a casing 2, a motor (not shown), a connector 3, and a connector fixing portion 4. At least a portion of the impeller 1 is installed and received in the casing 2, or the impeller 1 is installed and received in at least a portion of the casing 2.

[0032] Driven by the motor, the impeller 1 can rotate around the central axis OO'. The connector 3 is connected to a wire (not shown) led out from the motor, for example, the connector 3 is connected to one end of the wire, and the motor is connected to the other end of the wire. The connector 3 is fixed to the fan 100 through the connector fixing portion 4. In the embodiment of the present application, the specific structure of the impeller 1, the housing 2, the motor, the connector 3, and the implementation of the wire connecting the motor and the connector 4 can refer to the relevant technology, and the embodiment of the present application is not limited to this.

[0033] In the embodiment of the present application, the connector fixing portion 4 is disposed on the housing 2, and thus, the connector 3 is fixed on the housing 2 through the connector fixing portion 4. Figure 1 As shown, the connector fixing portion 4 can be arranged to protrude from the surface of the housing 2, or, as shown in FIG. Figure 2 As shown, the connector fixing portion 4 may also be arranged not to protrude from the surface of the housing 2 but to be arranged inside the housing 2 . Figure 1 and Figure 2 The position of the connector fixing portion 4 is described as an example, and the present application does not limit this.

[0034] The implementation of the connector 3 will be schematically described below.

The main body 31 includes a first surface 311 (see Figure 4 , also referred to as the lower bottom surface), the second surface 312 (see Figure 3 , which may also be referred to as an upper bottom surface) and a main body side surface 313 connecting the first surface 311 and the second surface 312.

[0036] For example, the first surface 311 and the second surface 312 are two surfaces of the main body 31 that are arranged opposite to each other and parallel to each other. The first surface 311 is provided with a first interface 51. As mentioned above, the connector 3 is connected to the motor through a wire, and the connector 3 is connected to one end of the wire, and the motor is connected to the other end of the wire, then the first interface 51 is an interface adapted to one end of the wire. The second surface 312 of the main body 31 is provided with a second interface 52. The connector 3 is connected to other structures through the second interface 52, and the second interface 52 is adapted to the interface on the other structure. For example, the connector 3 is connected to the interface on the actual machine side substrate (actual machine side interface) through the second interface 52, and the second interface 52 is adapted to the actual machine side interface.

[0037] like Figure 3 and Figure 4 As shown, the flange portion 32 of the connector 3 is protruded around the main body side surface 313 of the main body portion 31. For example, the flange portion 32 protrudes in a direction perpendicular to the main body side surface 313, but the present application is not limited thereto, and it is sufficient to protrude from the main body portion 31. The flange portion 32 also includes a first flange surface 321 close to the first surface 311 of the main body, a second flange surface 322 close to the second surface 312 of the main body and parallel to the first flange surface 321, and a flange connecting the first flange surface 321 (see Figure 4 ) and the second flange surface 322 (see Figure 3 ) flange side 323.

[0038] The flange portion 32 can be disposed around any position of the main body side surface 313, for example, Figure 3 and Figure 4 As shown, the flange portion 32 is arranged on a side of the main body portion 31 close to its first surface 311, and the first surface 311 of the main body portion 31 and the first flange surface 321 of the flange portion 32 are located in the same plane. In addition, the flange portion 32 can also be arranged on a side of the main body portion 31 close to its second surface 312, and the first surface 312 of the main body portion 31 and the first flange surface 322 of the flange portion 32 are located in the same plane; or, the flange portion 32 can also be arranged in the middle position of the main body side surface 313, that is, the first flange surface 321 of the flange portion 32 and the first surface 311 of the main body portion 31 are not in the same plane, and the second flange surface 322 of the flange portion 32 and the second surface 312 of the main body portion 31 are also not in the same plane. In the embodiment of the present application, Figure 3 and Figure 4 The connector shown is used as an example for illustration, but the present application is not limited thereto.

[0039] The following is a schematic illustration of an embodiment of the connector fixing portion 4 .

[0040] Figure 5is a schematic diagram of an implementation of a connector fixing portion of an embodiment of the present application, such as Figure 5 As shown, the connector fixing portion 4 includes a first receiving portion 41 and a fitting component 42 . Figure 6 yes Figure 3 The connector shown is secured to Figure 5 The overall schematic diagram of the connector fixing part is shown in FIG. Figure 7 yes Figure 3 The connector shown is secured to Figure 5 A partial schematic diagram of the connector fixing portion is shown in FIG. Figure 6 and Figure 7 As shown, the first receiving portion 41 receives at least a portion of the connector 3 , and the fitting component 42 fixes the connector 3 in the first receiving portion 41 , thereby fixing the connector 3 in the connector fixing portion 4 .

[0041] Figure 8 for Figure 5 The partial schematic diagram of the connector fixing part shown in FIG. 4 shows a part of the connector fixing part 4 after the connector 3 and the fitting part 42 are removed. Figure 8 As shown, the first receiving portion 41 of the connector fixing portion 4 includes a bottom surface 411 and a side surface 412 , and the bottom surface 411 is in a step shape, for example.

[0042] Please combine Figure 6 and Figure 7 When the connector 3 is disposed in the first receiving portion 41, the bottom surface 411 of the first receiving portion 41 contacts at least a portion of the first surface 311 of the connector 3. Figure 6 and Figure 7 The connector 3 is supported in the Z2 direction shown, and movement of the connector 3 in the Z2 direction is restricted. Figure 8 The side surface 412 shown includes three sides (the side surface 412 at least partially has a second opening, that is, the side surface 412 is not closed). Figure 6 and Figure 7 When the connector 3 is disposed in the first receiving portion 41, the side surface 412 of the first receiving portion 41 contacts the flange side surface 323 of the flange portion 32 of the connector 3, thereby, the three surfaces of the side surface 412 are respectively Figure 6 and Figure 7 The connector 3 is positioned in the X1 direction, the X2 direction, and the Y2 direction as shown, and the movement of the connector 3 in the X1 direction, the X2 direction, and the Y2 direction is restricted.

[0043] In some embodiments, Figure 8As shown, a second accommodating portion 43 is provided on at least a portion of the side surface 412 of the first accommodating portion 41 close to the fan 100. The second accommodating portion 43 includes a lower surface close to the bottom surface 411, an upper surface parallel to the lower surface, and a side surface connecting the upper surface and the lower surface. The distance between the lower surface of the second accommodating portion 43 and the bottom surface 411 is greater than or equal to the distance between the first flange surface 321 and the second flange surface 322 of the flange portion 32 of the connector 3.

[0044] The second receiving portion 43 is used to receive the fitting component 42, and the shape of the second receiving portion 43 matches the shape of the fitting component 42. Figure 5 and Figure 8 The engaging component 42 is engaged with the second accommodating portion 43 and at least partially protrudes from the second accommodating portion 43 . Figure 8 In the description, the second accommodation portion 43 is taken as a rectangular groove as an example, but the present application is not limited thereto. For example, the second accommodation portion 43 may also be a recessed portion with an irregular cross-section.

[0045] In some embodiments, the fitting component 42 is a component that matches the shape of the second receiving portion, for example, Fig. 9 is with Figure 8 The schematic diagram of the second receiving portion 43 matching the interlocking component 42 is shown, Figure 8 In the embodiment, the second receiving portion 43 has a second opening on one side, and correspondingly, the fitting component 42 matched with the second receiving portion 43 is an annular component having a first opening on the same side, for example Fig. 9 shown.

[0046] Please combine Figure 6 and Figure 7 When the connector 3 is arranged in the first accommodating portion 41, the flange portion 32 of the connector 3 is arranged between the bottom surface 411 of the first accommodating portion 41 and the portion of the fitting component 42 that exceeds the second accommodating portion 43. When the distance between the lower surface of the second accommodating portion 43 and the bottom surface 411 is set equal to the distance between the first flange surface 321 and the second flange surface 322 of the flange portion 32 of the connector 3, the second flange surface 322 of the flange portion 32 contacts the portion of the fitting component 42 that exceeds the second accommodating portion 43, thereby, the fitting component 42 is arranged in Figure 6 and Figure 7 The connector 3 is positioned in the Z1 direction as shown, and movement of the connector 3 in the Z1 direction is restricted.

[0047] In some embodiments, Figure 8 As shown, the connector fixing portion 4 further includes a positioning portion 44, which is disposed in the first accommodating portion 41 and is located on a side where the first accommodating portion 41 is provided with the second opening, and the positioning portion 44 protrudes from the bottom surface 411. Figure 6 and Figure 7When the connector 3 is disposed in the first receiving portion 41, the flange portion 32 of the connector 3 is located at a portion of the flange side surface 323 on one side of the second opening of the first receiving portion 41, and contacts the side surface of the positioning portion 44 facing the second opening, thereby the positioning portion 44 is in contact with the second opening. Figure 6 and Figure 7 The connector 3 is positioned in the Y1 direction as shown, and movement of the connector 3 in the Y1 direction is restricted.

[0048] In some embodiments, Figure 8 As shown, the connector fixing portion 4 further includes a third receiving portion 45, which is used to receive a wire (not shown) connecting the motor and the connector 3. The third receiving portion 45 is disposed on one side of the bottom surface 411 of the first receiving portion 41 and communicates with the first receiving portion 41, and at least a portion of the wire passes through the third receiving portion 45.

[0049] In some embodiments, the third accommodating portion 45 is provided with a third opening on the same side as the second opening of the first accommodating portion 41. A wire guide portion 46 is provided at the third opening to facilitate wiring. Alternatively, the third accommodating portion 45 is closed on its side.

[0050] Through the above-mentioned embodiment, the connector fixing portion 4 is Figure 6 and Figure 7 The connector 3 is positioned in the X1 direction, X2 direction, Y1 direction, Y2 direction, Z1 direction and Z2 direction as shown, respectively, thereby fixing the connector 3 in the connector fixing part 4, and then fixing the connector 3 on the fan 100, which facilitates the automated connection operation of the connector with other structures and reduces the risk of wire breakage and unstable connector interface connection.

[0051] When using Figure 5 When the connector fixing part shown is used to fix the connector, the installation method of the connector can be: from the second opening of the first accommodating portion 41, the engaging component 42 is installed in the second accommodating portion 43 (if the engaging component 42 and the second accommodating portion 43 are integrally formed, this step can be omitted); from the second opening of the first accommodating portion 41, the flange portion 32 of the connector 3 is engaged with the bottom surface 411 of the first accommodating portion 41, the side surface 412 of the first accommodating portion 41, the portion of the engaging component 42 protruding from the second accommodating portion 43 and the positioning portion 44, thereby, under the joint action of the first accommodating portion 41, the engaging component 42 and the positioning portion 44, the connector 3 is fixed to the fan 100.

[0052] The above exemplifies the case where the first accommodation portion is provided with the second opening and the third accommodation portion is provided with the third opening. The following exemplifies the case where the side surfaces of the first accommodation portion and the third accommodation portion are closed.

[0053] Fig.10is a schematic diagram of another implementation of the connector fixing portion of the embodiment of the present application, such as Fig.10 As shown, the connector fixing portion 4 includes a first receiving portion 41 and a fitting component 42 . Fig.11 yes Figure 3 The connector shown is secured to Fig.10 The overall schematic diagram of the connector fixing part is shown in FIG. Fig.12 yes Figure 3 The connector shown is secured to Fig.10 A partial schematic diagram of the connector fixing portion shown in FIG. Fig.12 For along Fig.11 A schematic cross-sectional view of the AA' direction is shown, which shows the situation where the fitting component is arranged in the connector fixing portion. Fig.11 and Fig.12 As shown, the first receiving portion 41 receives at least a portion of the connector 3 , and the fitting component 42 fixes the connector 3 in the first receiving portion 41 , thereby fixing the connector 3 in the connector fixing portion 4 .

[0054] Fig.13 for Fig.10 A partial schematic diagram of the connector fixing portion shown in FIG. Fig.13 As shown, the first receiving portion 41 of the connector fixing portion 4 includes a bottom surface 411 and a side surface 412. Figure 6 and Figure 7 Similarly, when the connector 3 is disposed in the first receiving portion 41, the bottom surface 411 of the first receiving portion 41 contacts at least a portion of the first surface 311 of the connector 3. Fig.11 and Fig.12 The connector 3 is supported in the Z2 direction as shown to prevent the connector 3 from moving in the Z2 direction. Fig.13 The side surface 412 shown includes four sides (i.e., the side surface 412 is closed). When the connector 3 is disposed in the first receiving portion 41, the side surface 412 of the first receiving portion 41 contacts the flange side surface 323 of the flange portion 32 of the connector 3. Thus, the four sides of the side surface 412 are respectively Fig.11 and Fig.12 The connector 3 is positioned in the X1 direction, X2 direction, Y1 direction and Y2 direction as shown, and the movement of the connector 3 in the X1 direction, X2 direction, Y1 direction and Y2 direction is restricted.

[0055] In some embodiments, Fig.13 As shown, a second accommodating portion 43 is provided on the side surface 412 of the first accommodating portion 41, and the second accommodating portion 43 includes a lower surface close to the bottom surface 411, an upper surface parallel to the lower surface, and a side surface connecting the upper surface and the lower surface. The distance between the lower surface of the second accommodating portion 43 and the bottom surface 411 is greater than or equal to the distance between the first flange surface 321 and the second flange surface 322 of the flange portion 32 of the connector 3.

[0056] The second receiving portion 43 is used to receive the fitting component 42, and the shape of the second receiving portion 43 matches the shape of the fitting component 42. Fig.10 As shown, the engaging component 42 is engaged with the second accommodating portion 43 and at least partially protrudes from the second accommodating portion 43 .

[0057] The fitting component 42 is a component that matches the shape of the second receiving portion 43, for example, Fig.14 is with Fig.13 The schematic diagram of the second receiving portion 43 matching the interlocking component 42 is shown, Fig.12 Shows Fig.13 The second receiving portion 43 in Fig.14 A cross-sectional view of the engagement of the interlocking parts 42 in FIG. Fig.12 and Fig.14 As can be seen in the figure, the fitting component 42 is an annular component with an opening on one side, and the opening of the fitting component 42 facilitates the fitting component 42 to be installed in the second receiving portion 43.

[0058] For example, the fitting member 42 is subjected to Fig.14 The force F in the direction indicated by the arrow reduces the distance d between the two ends of the fitting part 42 due to the force, and the fitting part 42 is deformed and reduced in size, so that it can enter the first receiving portion 41. When the fitting part 42 is placed at a position corresponding to the second receiving portion 43, the force applied to the fitting part 42 is cancelled, and the fitting part 42 rebounds under the action of the deformation elastic force, with a part of it fitting into the second receiving portion 43 and the other part protruding from the second receiving portion 43.

[0059] When the connector 3 is arranged in the first accommodating portion 41, the flange portion 32 of the connector 3 is arranged between the bottom surface 411 of the first accommodating portion 41 and the portion of the fitting component 42 that exceeds the second accommodating portion 43. When the distance between the lower surface of the second accommodating portion 43 and the bottom surface 411 is set equal to the distance between the first surface 321 and the second surface 322 of the flange portion 32 of the connector 3, the second surface 322 of the flange portion 32 contacts the portion of the fitting component 42 that exceeds the second accommodating portion 43, thereby, the fitting component 42 is arranged in Figure 6 The connector 3 is positioned in the Z1 direction as shown, and movement of the connector 3 in the Z1 direction is restricted.

[0060] Fig.15 is a cross-sectional schematic diagram of the interlocking components of the embodiment of the present application, such as Fig.15 As shown, the fitting member 42 has a circular cross section and contacts the flange portion 32 of the connector 3 .

[0061] Fig.16 is another cross-sectional schematic diagram of the interlocking component of the embodiment of the present application, such as Fig.16As shown, the cross section of the fitting component 42 is in a shape having at least one plane, such as a semicircle, a triangle, etc., and the plane of the cross section of the fitting component 42 contacts the flange portion 32 of the connector 3. In this case, when the connector 3 is subjected to an upward force F1, the flange portion 32 of the connector 3 generates a force F2 on the fitting component 42 that is perpendicular to the plane where the fitting component 42 contacts the flange portion 32, and the force generated by the plane on the flange portion 32 can be decomposed into F3 and F4. As a result, part of the force F3 can be offset, thereby improving the firmness of the connector.

[0062] In some embodiments, Fig.13 As shown, the connector fixing portion 4 further includes a third accommodating portion 45, which is used to accommodate a wire (not shown) connecting the motor and the connector 3. The third accommodating portion 45 is in communication with the first accommodating portion 41, and at least a portion of the wire passes through the third accommodating portion 45. The third accommodating portion 45 is closed on the side, or the third accommodating portion 45 has a third opening on the same side as the first accommodating portion 41 having the second opening.

[0063] Through the above-mentioned embodiment, the connector fixing portion 4 is Fig.11 The connector 3 is positioned in the X1 direction, X2 direction, Y1 direction, Y2 direction, Z1 direction and Z2 direction as shown, respectively, thereby fixing the connector 3 in the connector fixing part 4, and then fixing the connector 3 on the fan 100, which facilitates the automated connection operation of the connector with other structures and reduces the risk of wire breakage and unstable connector interface connection.

[0064] When using Fig.10 When the connector fixing part shown in the figure fixes the connector, the connector can be installed in the following manner: the connector 3 is placed on the bottom surface 411 of the first receiving portion 41, and then the fitting component 42 is installed in the second receiving portion 43, so that the flange portion 32 of the connector 3 is fixed to the bottom surface 411 of the first receiving portion 41, the side surface 412 of the first receiving portion 41 and the portion of the fitting component 42 protruding from the second receiving portion 43. Thus, under the joint action of the first receiving portion 41 and the fitting component 42, the connector 3 is fixed to the housing 2.

[0065] Figures 5 to 8 The following description is made by taking the example that both the first accommodation portion and the third accommodation portion have openings on their sides. Figures 10 to 13 The first receiving portion and the third receiving portion are both closed at the side, but the present application is not limited thereto. For example, the first receiving portion may be open at the side and the third receiving portion may be closed at the side. Fig. 9 As shown, or the first receiving portion can be closed on the side and the third receiving portion can be open on the side, and the corresponding engaging parts can be as shown. Fig.14 shown.

[0066] In some embodiments, in order to improve the waterproof performance of the fan, the engaging component and the connector fixing portion may be made of waterproof materials.

[0067] In some embodiments, in order to facilitate installation of the fitting component and the connector, at least one of the fitting component and the connector fixing portion may be made of an elastic material.

[0068] In some embodiments, the engaging component is, for example, a metal component or a polyurethane component, and the connector fixing portion is, for example, a polyurethane component. Fig. 9 The engaging parts shown are metal plates. Fig.14 The interlocking component shown is a metal ring, but the present application is not limited thereto.

[0069] Fig.17 is a cross-sectional schematic diagram of a connector of an embodiment of the present application being fixed to a connector fixing portion, such as Fig.17 As shown, the connector fixing portion 4 includes a protective component 47, which is disposed around the connector 3. For example, the protective component 47 is disposed around the side of the connector 3 and at least protrudes from the first accommodating portion 41, so that when the portion of the connector 3 protruding from the first accommodating portion 41 is subjected to a force applied from the outside, the protective component 47 can play an effective protective role, thereby improving the impact resistance of the fan.

[0070] In some embodiments, see Fig.17 At least a portion of the protective component 47 may be disposed between the connector 3 and the first accommodating portion 41, for example, may be disposed in a partial gap between the connector 3 and the first accommodating portion 41. Thus, the waterproof performance and impact resistance of the fan can be further improved.

[0071] In some embodiments, the fan 100 is connected to the actual machine side substrate 6 through the connector 3. Fig.17 The portion of the connector 3 protruding from the first receiving portion 41 is connected to the real machine side interface 61 on the real machine side substrate 6, and the protective component 47 is disposed between the real machine side interface 61 and the first receiving portion 41, for example, it can be disposed in a partial gap between the real machine side interface 61 and the first receiving portion 41. In this way, the waterproof performance of the fan can be further improved.

[0072] In some embodiments, the protection component 46 and the engaging component 42 are integrally formed, but the present application is not limited thereto.

[0073] In some embodiments, the protection component 47 is an elastic component, thereby facilitating installation of the protection component.
