[0048] Reference Figure 1-17 , Figure 18-24 ,or Figure 25-28 The embodiment of the present invention proposes a steering mechanism 1, including a motor 100, an electric main body 200 and a first connecting member 300; the motor 100 includes a motor body 110 and an output shaft 120, the output shaft 120 can rotate around a first central axis relative to the motor body 110, and the motor body 110 is installed on the electric main body 200; the first connecting member 300 can rotate around a second central axis relative to the electric main body 200, and the first connecting member 300 is transmission-connected to the output shaft 120; the motor 100 is used to realize the rotational movement of the electric main body 200 relative to the first connecting member 300.

[0049] When the output shaft 120 of the motor 100 rotates, the power-consuming body 200 can be rotated relative to the first connecting member 300 around the second central axis, thereby adjusting the use angle of the power-consuming body 200 .

[0050] Reference Figure 1-17 or Figure 18-24 , the power-consuming subject 200 is fixed circumferentially around the first central axis relative to the motor body 110; the first central axis is coaxial with the second central axis, and the first connecting member 300 is fixed circumferentially around the first central axis relative to the output shaft 120. In this implementation, the steering mechanism 1 can realize the steering of the power-consuming subject 200 relative to the first connecting member 300. When the output shaft 120 rotates relative to the motor body 110, the power-consuming subject 200 and the motor body 110 are the first whole, the output shaft 120 and the first connecting member 300 are the second whole, and the first whole rotates relative to the second whole around the first central axis.

[0053] In the steering mechanism 1 of the embodiment of the present invention, the power-consuming subject 200 may be a desk lamp, a fan head, a mobile phone, a tablet, a speaker, a camera, etc.

[0055] In the steering mechanism 1 of the embodiment of the present invention, referring to 6, Figure 8 , 20 , the power-consuming entity 200 is circumferentially fixed relative to the motor body 110 around the first center axis, which means that when the motor body 110 and the output shaft 120 rotate relative to each other, when the motor body 110 rotates around the first center axis and drives the power-consuming entity 200 to rotate along it, it can be understood that the power-consuming entity 200 is allowed to slide relative to the motor body 110 along the first center axis.

[0056] The first connecting member 300 is circumferentially fixed relative to the output shaft 120 around the first central axis. When the motor body 110 and the output shaft 120 rotate relative to each other, it can be understood that the first connecting member 300 is allowed to slide relative to the output shaft 120 along the first central axis.

[0057] For example, refer to Figure 6 , Figure 8 , 20 The electrical main body 200 is provided with a first fixed cavity 204, and the motor main body 110 is accommodated in the first fixed cavity 204. The electrical main body 200 is circumferentially fixed relative to the cavity wall of the first fixed cavity 204. The outer peripheral shape of the electrical main body 200 is adapted to the cavity wall shape of the first fixed cavity 204. The cross section of the motor main body 110 is a non-circular shape, such as a rectangle, an ellipse, a polygon, a racetrack, or other non-circular shapes. For example, the cross section of the motor main body 110 is a figure formed by combining a circle and a rectangle. The first fixed cavity 204 is a part of the accommodation space 201.

[0058] In other implementations of the steering mechanism 1 of the embodiment of the present invention, the motor body 110 is fixedly installed on the power-consuming body 200 .

[0060] In other implementations of the steering mechanism 1 of the embodiment of the present invention, refer to Figure 27-28 The output shaft 120 is connected to the first connecting member 300 via a belt transmission mechanism 700 (or a chain transmission mechanism).

[0061] In other implementations of the steering mechanism 1 of the embodiment of the present invention, the output shaft 120 is transmission-connected to the first connecting member 300 via a universal joint.

[0063] In other implementations of the steering mechanism 1 according to the embodiment of the present invention, the first connecting member 300 is fixedly mounted on the output shaft 120 .

[0064] In the steering mechanism 1 of the embodiment of the present invention, referring to Figure 5 , 9 , 17, 20, 21, the steering mechanism 1 also includes a second connecting member 400 fixed along the second central axis relative to the power-consuming body 200, the second connecting member 400 is detachably mounted on the power-consuming body 200, the second connecting member 400 is provided with a first rotating hole 401 coaxial with the second central axis, the first connecting member 300 is provided with a first rotating shaft 310 adapted to the first rotating hole 401, the first rotating shaft 310 is rotatably mounted on the first rotating hole 401, and the second connecting member 400 is fixed along the second central axis relative to the first connecting member 300. The second connecting member 400 is used to realize the support of the first connecting member 300 to the power-consuming body 200, and the rotation of the power-consuming body 200 relative to the first connecting member 300.

[0065] In one implementation of the steering mechanism 1 of the embodiment of the present invention, the second connecting member 400 is installed on the power-consuming body 200 by means of a snap connection or a fastener connection.

[0066] In one implementation of the steering mechanism 1 of the embodiment of the present invention, referring to Figure 5 , 9 , 17, 20, 21, the second connecting member 400 includes a first sleeve 410 and a second sleeve 420 which are both detachably mounted on the electrical main body 200, the first rotating hole 401 extends to the first sleeve 410 and the second sleeve 420, the two ends of the first rotating shaft 310 are rotatably inserted in the first sleeve 410 and the second sleeve 420, the first connecting member 300 has a first abutting surface 301 and a second abutting surface 302, the first sleeve 410 and the second sleeve 420 are respectively abutted against the first abutting surface 301 and the second abutting surface 302 to fix the second connecting member 400 relative to the first connecting member 300 along the second center axis.

[0067] Exemplarily, the first sleeve 410 and the second sleeve 420 are both cylindrical structures with a hollow cavity, the hollow cavity of the first sleeve 410 is a part of the first rotating hole 401 , and the hollow cavity of the second sleeve 420 is a part of the first rotating hole 401 .

[0068] Obviously, the first sleeve 410 and the second sleeve 420 are both fixed along the second central axis relative to the power-consuming body 200, and the first abutting surface 301 abuts against the first sleeve 410, and the second abutting surface 302 abuts against the second sleeve 420, so that the first connecting member 300 supports the power-consuming body 200. Exemplarily, the first abutting surface 301 can be a plane, a rotation surface coaxial with the second central axis, etc., and the second abutting surface 302 can be a plane, a rotation surface coaxial with the second central axis, etc.

[0069] Exemplarily, the junction between the first rotating shaft 310 and the output shaft 120 is located in the first sleeve 410 .

[0070] The second connecting member 400 is configured as a first sleeve 410 and a second sleeve 420, which facilitates the manufacture of the second connecting member 400 and the installation of the second connecting member 400 and other components of the steering mechanism 1. The first sleeve 410 and the second sleeve 420 are respectively sleeved with both ends of the first rotating shaft 310, thereby improving the rotation stability of the steering mechanism 1.

[0071] In the steering mechanism 1 of the embodiment of the present invention, referring to Fig. 9 , 17 20, a first clamping portion 411 is respectively provided on two opposite sides of the first sleeve 410, and the electrical main body 200 is provided with two second clamping portions 210, and the two first clamping portions 411 are respectively clamped and assembled with the two second clamping portions 210; a third clamping portion 421 is respectively provided on two opposite sides of the second sleeve 420, and the electrical main body 200 is provided with two fourth clamping portions 220, and the two third clamping portions 421 are respectively clamped and assembled with the two fourth clamping portions 220.

[0072] For example, refer to Fig. 9 , 17 , 20, etc., the first clamping portion 411 is a clamping protrusion, the second clamping portion 210 is a clamping groove, the third clamping portion 421 is a clamping protrusion, and the fourth clamping portion 220 is a clamping groove; in other implementations, the first clamping portion 411 can be a clamping groove, the second clamping portion 210 is a clamping protrusion, the third clamping portion 421 is a clamping groove, and the fourth clamping portion 220 is a clamping protrusion.

[0073] The clamping assembly of the first clamping portion 411 and the second clamping portion 210 can realize the connection between the first sleeve 410 and the electrical body 200 (which can be a movable connection or a fixed connection), and the clamping assembly of the third clamping portion 421 and the fourth clamping portion 220 can realize the connection between the second sleeve 420 and the electrical body 200 (which can be a movable connection or a fixed connection), and because the first rotating shaft 310 is rotatably inserted in the first sleeve 410 and the second sleeve 420, respectively, the second connecting member 400 is further fixed through the first rotating shaft 310.

[0074] Furthermore, the first sleeve 410 and the second sleeve 420 are interchangeable, which further reduces the manufacturing cost of the steering mechanism.

[0075] In the steering mechanism 1 of the embodiment of the present invention, referring to 12, 13, 14, 15, 21, 22, 23, 24, etc., the first connecting member 300 includes a connecting head 320, a connecting block 330 and a first rotating shaft 310, the connecting head 320 is provided with a first connecting portion 321, the connecting block 330 is circumferentially fixed relative to the first connecting portion 321 around the second central axis, and the connecting block 330 is arranged on the first rotating shaft 310. The first connecting portion 321 is a first connecting groove 303 adapted to the connecting block 330, and the connecting block 330 is installed in the first connecting groove 303, or the first connecting portion 321 is a connecting protrusion, the connecting block 330 is provided with a second connecting groove adapted to the connecting protrusion, and the connecting protrusion is installed in the second connecting groove.

[0076] For example, refer to Fig.12 , 21 The connecting block 330 is integrally arranged on the first rotating shaft 310, and the cross-section of the connecting block 330 is a non-circular shape. The first connecting portion 321 is a first connecting groove 303 adapted to the connecting block 330, such as an elliptical, polygonal, runway shape, etc. For example, the cross-section of the connecting block 330 is formed by the combination of a circle and a rectangle.

[0077] In some other implementations of the steering mechanism 1 of the embodiment of the present invention, the connecting head 320 is fixedly mounted on the connecting block 330 , or the connecting head 320 and the connecting block 330 are integrally formed.

[0078] In the steering mechanism 1 of the embodiment of the present invention, referring to Fig.12 , 13 , 21, 24, etc., the first abutting surface 301 is located at the connecting block 330, and the second abutting surface 302 is located at the connecting head 320. Obviously, the first sleeve 410 abuts against the first abutting surface 301, and the connecting block 330 and the first connecting part 321 abut against each other in the direction of the second center axis, so that the connecting block 330 and the first connecting part 321 are not easily separated during the transmission process.

[0079] For example, refer to Fig.13 , the first rotating shaft 310 passes through the connecting head 320 and extends into the second sleeve 420 .

[0080] In the steering mechanism 1 of the embodiment of the present invention, referring to Figure 3 , 19 The electrical main body 200 is provided with a receiving space 201 and an escape space 202 for the first connecting member 300 to escape. The motor 100 and the second connecting member 400 are both located in the receiving space 201. The escape space 202 is interconnected with the receiving space 201, and the escape space 202 extends to the surface of the electrical main body 200. The first connecting member 300 is partially received in the receiving space 201, and the first connecting member 300 extends to the outside of the electrical main body 200 through the escape space 202, so as to facilitate the connection between the first connecting member 300 and the support rod 22. The motor 100 and the second connecting member 400 are both arranged in the receiving space 201, so that the structure of the steering mechanism is more compact.

[0081] Exemplarily, the power user 200 can make reciprocating swinging motion relative to the first connecting member 300, and the avoidance space 202 prevents the power user 200 from interfering with the first connecting member 300 within its swinging range. Preferably, the swinging range of the power user 200 is within 150°.

[0082] In the steering mechanism 1 of the embodiment of the present invention, referring to Figure 2 , 19 The steering mechanism 1 further includes a cover 500, which is detachably mounted on the power-consuming body 200. The accommodation space 201 extends to the surface of the power-consuming body 200. The cover 500 is used to close the accommodation space 201. The cover 500 is arranged on the back of the power-consuming body 200, and the avoidance space 202 passes through the cover 500. The benefit of setting the cover 500 is that the power-consuming body 200 is more beautiful and it is convenient to disassemble and assemble the various components in the accommodation space 201.

[0083] In the steering mechanism 1 of the embodiment of the present invention, referring to 12, 22, etc., the first connecting member 300 extends from outside the accommodation space 201 to inside the accommodation space 201, and the first connecting member 300 has an avoidance surface 304, which is a partial cylindrical surface coaxial with the second central axis, and the avoidance surface 304 is located in the accommodation space 201. The benefit of providing the avoidance surface 304 is that it is convenient to set the volume of the accommodation space 201 to be smaller, thereby making the steering mechanism 1 more compact.

[0084] In the steering mechanism 1 of the embodiment of the present invention, the electrical body 200 is provided with a accommodating space 201 and an avoidance space 202 for the first connecting member 300 to avoid, the motor 100 and the first connecting member 300 are both located in the accommodating space 201, the avoidance space 202 is interconnected with the accommodating space 201, and the avoidance space 202 extends to the surface of the electrical body 200.

Obviously, the battery 600 is used to supply power to the power-consuming body 200 and the motor 100.

[0086] The embodiment of the present invention further provides a fan, referring to Figure 1 , 18 etc., the support part 2 and the steering mechanism 1 , the first connecting member 300 of the steering mechanism 1 is installed on the support part 2 , and the electrical main body 200 is a fan head 200 .

[0087] Exemplarily, the support portion 2 includes a base 21 and a support rod 22, and the support rod 22 is mounted on the base 21.

[0088] In other implementations of the embodiments of the present invention, the support portion 2 may be a clamping support portion, a neck-hanging support portion, etc.

[0090] The rotating connector 400 in the rotating connection structure 1A can be detachably mounted on the first main body 200, and the rotating connector 400 can be manufactured separately, which makes it convenient to use a material different from that of the first main body 200 for the rotating connector 400, so that the rotating connector 400 is not easily damaged during use, thereby saving costs; on the other hand, since the rotating connector 400 is detachably mounted on the first main body 200, it is convenient to replace the rotating connector 400 after it is damaged.
