[0084] In order to better understand the above objects, features and advantages of the present application, the present application will now be described in more detail in conjunction with the drawings and specific embodiments. It should be noted that, unless inconsistent, the embodiments and features of the present application can be combined with each other.

[0085] In the following description, numerous details are set forth in order to provide a thorough understanding of the present application; however, the present application may be embodied in other forms than those described herein, and the scope of protection of the present application is not limited to the specific examples disclosed below.

[0086] Hereinafter, a hinge assembly 100, a home appliance, and a rotating device according to several embodiments of the present application will be described with reference to FIGS.

[0087] Example 1: As shown in FIG. 6, in one embodiment of a first aspect of the present application, the present application provides a hinge assembly 100 including a rotating shaft 102, a first connecting part 104, and a second connecting part 106.

[0088] Specifically, the first connecting part 104 and the second connecting part 106 are both provided on the rotating shaft 102, the second connecting part 106 is located on one side of the first connecting part 104 in the axial direction of the rotating shaft 102, the second connecting part 106 being suitable for rotating around the rotating shaft 102, and an adjustment part 108, the adjustment part 108 being connected to the rotating shaft 102, and the adjustment part 108 being suitable for pressing the second connecting part 106 in the axial direction of the rotating shaft 102.

[0089] The hinge assembly 100 according to the present application includes a rotating shaft 102, and a first connecting part 104 and a second connecting part 106 provided on the rotating shaft 102. In the axial direction of the rotating shaft 102, the second connecting part 106 is located on one side of the first connecting part 104, i.e., the second connecting part 106 is located outside the first connecting part 104. This allows the first connecting part 104 and the second connecting part 106 to be attached to the rotating shaft 102 in this order, thereby improving the assembly efficiency of the product and increasing the reliability of the product. 04 can avoid the second connecting part 106 when the second connecting part 106 rotates, so that the second connecting part 106 has a larger rotation angle and is suitable for various application scenes; however, the hinge assembly 100 further includes an adjustment part 108, which is connected to the rotating shaft 102 and is suitable for pressing the second connecting part 106 in the axial direction of the rotating shaft 102 to adjust the axial pressure received by the second connecting part 106, thereby improving the reliability of the hinge assembly 100.

[0090] Specifically, the adjustment part 108 can press the second connecting part 106 in the axial direction of the rotation shaft 102, and the magnitude of the axial pressure on the second connecting part 106 can be adjusted. The greater the axial pressure received by the second connecting part 106, the greater the resistance the second connecting part 106 receives when rotating, and thus the greater the force that allows it to rotate around the rotation shaft 102; therefore, the adjustment part 108 can adjust the magnitude of the force required to rotate the second connecting part 106; and by adjusting the axial pressure received by the second connecting part 106, the frictional force between the second connecting part 106 and the adjacent parts can be adjusted; that is, the greater the axial pressure received by the second connecting part 106, the greater the frictional force with the adjacent structure; when the frictional force and the force that allows the second connecting part 106 to rotate can be offset, the second connecting part 106 is fixed in a predetermined position, and further, the parts connected to the second connecting part 106 are fixed in a predetermined position without arbitrarily rotating, which improves the reliability of the hinge assembly 100. It should be understood that the resistance experienced by the second connection part 106 when it rotates includes frictional forces occurring between the second connection part 106 and parts adjacent to the second connection part 106 in the axial direction.

[0091] Specifically, the first connecting part 104 and the second connecting part 106 may be fitted to the rotating shaft 102 in this order in the direction of gravity, which makes assembly easy and allows the distance between the first connecting part 104 and the second connecting part 106 in the axial direction of the rotating shaft 102 to be adjusted as desired, thereby improving the versatility of the hinge assembly 100.

[0092] In particular, the first connecting part 104 can rotate around the rotation axis 102 or the first connecting part 104 is fixed to the rotation axis 102 .

[0093] Specifically, the first connecting part 104 is fixed to the rotating shaft 102 , so that the rotating shaft 102 can be fixed by the first connecting part 104 .

[0094] Example 2: As shown in FIGS. 6 and 8, an embodiment of the present application includes the features described in the above embodiments, and further, the adjustment component 108 includes a fastening component 1080.

[0096] In this embodiment, the adjustment part 108 includes a fastening part 1080, the fastening part 1080 is provided at one end of the rotating shaft 102 and a limiting structure is provided at the other end, the first connecting part 104 and the second connecting part 106 are provided between the limiting structure and the fastening part 1080, and the fastening part 1080 can adjust the pressing force applied to the second connecting part 106, however, both the fastening part 1080 and the rotating shaft 102 are provided with a thread structure, and the fastening part 1080 and the rotating shaft 102 are screwed together through the thread structure, so that the fastening part 1080 can adjust the pressing force applied to the second connecting part 106, and the screwing is reliable, and when the fastening part 1080 is removed from the rotating shaft 102, the parts on the rotating shaft 102 can be easily removed and replaced.

[0100] In this embodiment, the adjustment part 108 further includes a vibration damping part, which is connected to the rotating shaft 102, and the vibration damping part can increase the resistance that the second connecting part 106 experiences when rotating, thereby increasing the frictional force generated when the second connecting part 106 rotates, and also increasing the force required to rotate the second connecting part 106, thereby improving the stability of the hinge assembly 100. A vibration damping part may be selectively provided between the first connecting part 104 and the fastening part 1080 and between the second connecting part 106 and the first connecting part 104.

[0101] Specifically, the magnitude of the force required to rotate the second connection part 106 can be adjusted by increasing or decreasing the vibration-damping part. For example, when the fastening part 1080 is stopped at the same position of the rotating shaft 102, the resistance that the second connection part 106 receives when rotating can be increased by adding a vibration-damping part, and this increases the force required to rotate the second connection part 106, i.e., a larger force is applied to rotate the second connection part. When the resistance that the second connection part 106 receives when rotating is greater than or equal to the force applied to the second connection part 106 by other structures or the user, the hinge assembly 100 is maintained in the current state, i.e., the second connection part 106 is maintained not to move, thereby improving the stability of the hinge assembly 100.

[0107] Specifically, in the axial direction of the rotation shaft 102, both ends of the pad 1086 abut against other structures, i.e., the pad 1086 can press against the structures on both sides, thereby increasing the force required for the structures on both sides of the pad 1086 to rotate, thereby improving the stability of the hinge assembly 100.

[0108] Example 5: An embodiment of the present application includes the features described in any of the above embodiments, and further, the angle of rotation of the second connecting part 106 around the rotation axis 102 is greater than or equal to 0° and less than or equal to 360°.

[0119] Specifically, there are three fixing holes 1040, and among the lines connecting the three fixing holes 1040 and the center of the rotation shaft 102, the included angle between two adjacent lines is 90°.

[0123] In this embodiment, the number of first connecting parts 104 is at least two, and the first connecting parts 104 play a fixing role. Providing at least two first connecting parts 104 can improve the fixing strength of the hinge assembly 100, and adding more first connecting parts 104 can increase the axial pressing force applied to the second connecting part 106, and further improve the stability of the hinge assembly 100.

[0124] Furthermore, as shown in FIG. 11, the structure of at least one of the at least two first connection parts 104 is the same as the structure of the second connection part 106 .

[0127] Specifically, the parts fixedly connected to the rotating shaft 102 may be welded to the rotating shaft 102 or may have an axial tangent plane at the matching portion to the rotating shaft 102. For example, the rotating shaft 102 may have an axial tangent plane at the matching portion to the pad 1086, and the shape of the through hole of the pad 1086 may be designed to match the rotating shaft 102 having a tangent portion, thereby preventing the pad 1086 from rotating on the rotating shaft 102.

Moreover, the included angle set between the mounting portion 1062 and the connecting portion 1060 can increase the connection area between the second connecting component 106 and other structures.

[0134] Specifically, the connection portion 1060 and the mounting portion 1062 are plate-shaped, and the connection portion 1060 and the mounting portion 1062 have an included angle, which increases the connection area of ​​the mounting portion 1062 with other structures and improves the connection strength.

[0135] Furthermore, as shown in FIG. 11, a reinforcing rib 1066 is provided at the location where the connecting portion 1060 and the mounting portion 1062 are connected.

[0136] In this embodiment, a reinforcing rib 1066 is provided at the location where the connecting portion 1060 and the mounting portion 1062 are connected, thereby improving the connection strength between the mounting portion 1062 and the connecting portion 1060.

[0137] Furthermore, the connection portion 1060 and the mounting portion 1062 are of one piece construction.

[0138] In this embodiment, the connecting portion 1060 and the mounting portion 1062 are of an integral structure, which improves the connection strength between the mounting portion 1062 and the connecting portion 1060 .

[0139] Specifically, the second connecting component 106 is curved, thereby forming a connecting portion 1060 and a mounting portion 1062 having an included angle.

[0140] Furthermore, as shown in FIG. 9, the connecting portion 1060 is provided with a clearance hole 1064 , which is suitable for communicating with the fixing hole 1040 of the first connecting part 104 in the axial direction of the rotating shaft 102 .

Specifically, one of the second connecting part 106 and the first connecting part 104 is connected to the head of the electric fan, and the other of the second connecting part 106 and the first connecting part 104 is connected to the vertical pole assembly, and further adjusts the pitch angle or swing angle of the electric fan head.

[0155] Example 14: According to a third aspect of the present invention, there is further provided a rotation device including the hinge assembly 100 according to any one of the embodiments of the first aspect described above.

[0156] The rotation device according to the third aspect of the present application includes the hinge assembly 100 according to any of the embodiments of the first aspect described above, and therefore has all the beneficial effects of the hinge assembly 100.

[0159] Example 15: In one embodiment of the present application, the present application provides a fan 200 including a vertical pole assembly 202, a fan head 204, and a hinge assembly 100.

[0160] Specifically, as shown in FIG. 12 , the hinge assembly 100 includes a rotating shaft 102, and a first connecting part 104 and a second connecting part 106 provided on the rotating shaft 102, where the first connecting part 104 is connected to a vertical column assembly 202, and the second connecting part 106 is connected to a fan head 204, and the second connecting part 106 is suitable for rotating around the rotating shaft 102, where the rotating shaft 102 is located in the middle of an end of the vertical column assembly 202 close to the fan head 204.

[0161] The electric fan 200 according to the present application includes a vertical pole assembly 202 and a fan head 204. The vertical pole assembly 202 and the fan head 204 are connected by a hinge assembly 100. The hinge assembly 100 includes a rotating shaft 102, a first connecting part 104 and a second connecting part 106 provided on the rotating shaft 102. The first connecting part 104 is connected to the vertical pole assembly 202, and the second connecting part 106 is connected to the fan head 204. The first connecting part 104 and the second connecting part 106 are connected to the vertical pole assembly 202 and the fan head 204. The part 106 can rotate around the rotation axis 102, thereby realizing the rotation of the fan head 204 and further realizing the adjustment of the blowing angle of the fan head 204, and the rotation axis 102 of the hinge assembly 100 is located at the end of the vertical pole assembly 202, that is, the hinge assembly 100 is connected to the back of the fan head 204 and the vertical pole assembly 202, which improves the stability of the fan head 204 and makes the fan 200 look more neat. In addition, the rotation axis 102 is located at the middle of the end of the vertical pole assembly 202 close to the fan head 204, which allows the fan head 204 to rotate at a larger angle during rotation and further realizing the adjustment of the pitch angle.

[0162] Specifically, the rotating shaft 102 is located in the middle of the end of the vertical column assembly 202 that is closer to the fan head 204, that is, the axis of the rotating shaft 102 and the center of the end of the vertical column assembly 202 are located in the same plane.

[0163] For example, when the end of the vertical column assembly 202 is circular, the projection of the axis of the rotating shaft 102 on the end face of the vertical column assembly 202 is located on the diameter of the end face of the vertical column assembly 202, and both ends of the rotating shaft 102 are at the same distance from the edges of the end face of the vertical column assembly 202.

[0164] Specifically, the second connecting part 106 is connected to the fan head 204, and the second connecting part 106 rotates around the rotation axis 102, so that the fan head 204 can rotate around the rotation axis 102; furthermore, the rotation axis 102 is located in the middle of the end of the vertical column assembly 202 close to the fan head 204, that is, the rotation axis 102 is located in the middle of the end of the vertical column assembly 202, so that the fan head 204 rotates around the middle of the end of the vertical column assembly 202, so that the center of gravity of the fan head 204 also rotates around the middle of the end of the vertical column assembly 202, so that the fan head 204 will not tilt because the center of gravity moves away from the center of the vertical column assembly 202 during rotation, thereby improving the stability of the fan head 204.

[0165] Furthermore, the electric fan 200 of the present application has better stability compared to a fan in which the rotating shaft 102 is provided on the edge of the end of the vertical pole assembly 202.

[0166] Example 16: As shown in FIG. 12, one embodiment of the present application includes the features described in the above embodiments, and further includes an axis about which the first connecting part 104 and the second connecting part 106 rotate relative to each other that is perpendicular to the length of the vertical column assembly 202.

[0167] In this embodiment, the axis about which the first connecting part 104 and the second connecting part 106 rotate relative to each other is perpendicular to the length of the vertical pole assembly 202, thereby realizing adjustment of the pitch angle of the fan head 204 and further increasing the blowing area of ​​the fan 200.

[0168] Specifically, the electric fan 200 may be a floor-mounted electric fan, in which case the upright assembly 202 is installed vertically, that is, the length direction of the upright assembly 202 is vertical.

[0169] Of course, the axis about which the first connecting part 104 and the second connecting part 106 rotate relative to each other may be parallel to the vertical column assembly 202, thereby realizing the left-right oscillating rotational movement of the fan head 204.

[0170] Example 17: One embodiment of the present application includes the features described in the above embodiment, and further includes a fan head 204 including a drive shaft 116 and blades attached to the drive shaft 116, and the center of the rotation shaft 102 and the axis of the drive shaft 116 overlap.

[0171] In this embodiment, the fan head 204 includes a drive shaft 116 and blades, the drive shaft 116 drives the blades to rotate and blow air to the outside, and the blades are distributed around the drive shaft 116, so that the drive shaft 116 is located in the middle of the fan 200, and the center of the rotating shaft 102 and the axis of the drive shaft 116 overlap, that is, the axis of the drive shaft 116 passes through the axis of the rotating shaft 102, so that while the fan head 204 rotates, the end of the vertical column assembly 202 always corresponds to the center of the fan head 204, so that the fan head 204 does not become eccentric during rotation, which further improves the stability of the fan head 204, and because the fan head 204 does not become eccentric during rotation, the fan head 204 can rotate at a larger angle.

[0172] Specifically, by installing the rotating shaft 102 at the center of the end of the vertical column assembly 202, the fan head 204 can always rotate around the center of the end of the vertical column assembly 202 during rotation, and since the fan 200 includes the driving shaft 116, the driving shaft 116 also rotates around the center of the end of the vertical column assembly 202, and while the fan head 204 rotates, the axis of the driving shaft 116 always passes through the center of the rotating shaft 102, so that while the fan 200 rotates, the fan head 204 rotates around the center of the rotating shaft 102. The fan head 204 rotates with the distance between the center of the rotating shaft 102 and the drive shaft 116 as a radius, which is equivalent to fixedly connecting the center of the fan head 204 to the center of the end of the vertical column assembly 202, so that the distance between the center of the fan head 204 and the center of the end of the vertical column assembly 202 does not change, thereby preventing the fan head 204 from becoming eccentric during rotation. The fact that the fan head 204 does not become eccentric during rotation improves the aesthetics of the rotating fan 200, and allows the fan 200 to rotate at a larger angle.

[0173] Specifically, the electric fan 200 includes a motor having a drive shaft 116 that is connected to the blades.

[0174] Example 18: One embodiment of the present application includes the features described in the above embodiments and further includes a limiting component (not shown) provided on the fan head 204 and / or the upright assembly 202, the limiting component being suitable for limiting the rotation of the fan head 204 between the first position 112 and the second position 114.

[0175] In this embodiment, a limiting component may be provided to limit the range of rotation of the fan head 204 such that the fan head 204 may rotate between the first position 112 and the second position 114 .

[0176] Specifically, the limiting element may be provided on the fan head 204 or on the upright assembly 202, and of course, both the fan head 204 and the upright assembly 202 may have limiting elements.

[0177] Specifically, while the fan head 204 rotates, the limiting component abuts against the fan head 204 or the vertical column assembly 202, thereby realizing the limiting of the rotation angle of the fan head 204.

[0178] Furthermore, the rotation angle of the fan head 204 rotating from the horizontal position 110 to the first position 112 below the fan 200 is greater than 0° and less than 6°, and the rotation angle of the fan head 204 rotating from the horizontal position 110 to the second position 114 above the fan 200 is greater than 0° and less than 90°, where the horizontal position 110 is located between the first position 112 and the second position 114, and when the fan head 204 is located at the horizontal position 110, the axis of the drive shaft 116 is perpendicular to the length of the upright assembly 202.

[0179] In this embodiment, as shown in FIG. 13 and FIG. 14, the horizontal position 110 is located between the first position 112 and the second position 114, and the fan head 204 can move from the horizontal position 110 to the first position 112 and the second position 114, respectively. When the fan head 204 is located at the horizontal position 110, the axis of the drive shaft 116 is perpendicular to the length of the vertical column assembly 202, i.e., when the fan head 204 is located at the horizontal position 110, the blowing direction of the fan 200 is is horizontal or approximately horizontal, however, the hinge assembly 100 can realize the adjustment of the pitch angle of the fan head 204, and FIG. 13 shows a schematic diagram of the fan head 204 moving to the first position 112, in which the rotation angle of the fan head 204 rotating from the horizontal position 110 to the first position 112 downward of the fan 200 is greater than or equal to 0° and less than or equal to 6°, that is, the depression angle of the downward movement of the fan head 204 from the horizontal position 110 is greater than or equal to 0° and less than or equal to 6°. FIG. 14 shows a schematic diagram of the fan head 204 moving to the second position 114. The rotation angle of the fan head 204 rotating from the horizontal position 110 to the second position 114 upward of the fan 200 is greater than 0° and less than 90°, that is, the elevation angle of the upward movement of the fan head 204 from the horizontal position 110 is greater than 0° and less than 90°, that is, the fan head 204 can achieve a depression angle of 6° and an elevation angle of 90°, thereby expanding the blowing range of the fan 200.

[0180] Specifically, the first position 112 is located below the horizontal position 110 , and the second position 114 is located above the horizontal position 110 .

[0181] Example 19: As shown in FIG. 12 , an embodiment of the present application includes the features described in the above embodiments, and further, the hinge assembly 100 further includes a fastening part 1080, the fastening part 1080 is provided on the rotating shaft 102 and located at one end of the rotating shaft 102, the rotating shaft 102 and the fastening part 1080 are both provided with a thread structure, the fastening part 1080 and the rotating shaft 102 are screwed together by the thread structure, however, a limiting structure is further provided on the other end of the rotating shaft 102, and the first connecting part 104 and the second connecting part 106 are located between the limiting structure and the fastening part 1080.

[0182] In this embodiment, a fastening part 1080 is provided at one end of the rotating shaft 102, and a limiting structure is provided at the other end. The first connecting part 104 and the second connecting part 106 are provided between the limiting structure and the fastening part 1080. The fastening part 1080 can adjust the pressing force applied to the second connecting part 106. However, both the fastening part 1080 and the rotating shaft 102 are provided with a thread structure, and the fastening part 1080 and the rotating shaft 102 are screwed together through the thread structure. This allows the fastening part 1080 to adjust the pressing force applied to the second connecting part 106, and the screwing is reliable. When the fastening part 1080 is removed from the rotating shaft 102, the components on the rotating shaft 102 can be easily removed and replaced.

[0183] Specifically, the rotating shaft 102 and the limiting structure provided at the end of the rotating shaft 102 are an integral structure, the rotating shaft 102 includes a bolt or a screw, and the fastening part 1080 includes a nut.

[0184] Specifically, the fastening part 1080 presses the second connecting part 106 in the axial direction of the rotating shaft 102, and the magnitude of the axial pressure on the second connecting part 106 can be adjusted. The greater the axial pressure received by the second connecting part 106, the greater the resistance the second connecting part 106 receives when rotating, and thus the greater the force that allows it to rotate around the rotating shaft 102; therefore, the fastening part 1080 can adjust the magnitude of the force required to rotate the second connecting part 106; and by adjusting the axial pressure received by the second connecting part 106, the frictional force between the second connecting part 106 and the adjacent parts can be adjusted; that is, the greater the axial pressure received by the second connecting part 106, the greater the frictional force with the adjacent structure; when the frictional force and the force that allows the second connecting part 106 to rotate can be offset, the second connecting part 106 is fixed in a predetermined position, and further, the parts connected to the second connecting part 106 are fixed in a predetermined position without rotating arbitrarily, which improves the reliability of the hinge assembly 100. It should be understood that the resistance experienced by the second connection part 106 when it rotates includes frictional forces occurring between the second connection part 106 and parts adjacent to the second connection part 106 in the axial direction.

[0185] In particular, the first connecting part 104 can rotate around the rotation axis 102 or the first connecting part 104 is fixed to the rotation axis 102 .

[0186] Specifically, the first connecting part 104 is fixed to the rotating shaft 102 , so that the rotating shaft 102 can be fixed by the first connecting part 104 .

[0187] Furthermore, as shown in FIG. 12, the hinge assembly 100 further includes a vibration-damping component provided on the rotating shaft 102, and the vibration-damping component is provided between the first connecting component 104 and the fastening component 1080.

[0188] In this embodiment, the vibration damping part is connected to the rotating shaft 102, and the vibration damping part can increase the resistance that the second connecting part 106 experiences when rotating, thereby increasing the frictional force generated when the second connecting part 106 rotates, and also increasing the force required to rotate the second connecting part 106, and further improving the stability of the hinge assembly 100. A vibration damping part may be selectively provided between the first connecting part 104 and the fastening part 1080 and between the second connecting part 106 and the first connecting part 104.

[0189] Specifically, the magnitude of the force required to rotate the second connection part 106 can be adjusted by increasing or decreasing the vibration-damping part. For example, when the fastening part 1080 is stopped at the same position of the rotating shaft 102, the resistance that the second connection part 106 receives when rotating can be increased by adding a vibration-damping part, and this increases the force required to rotate the second connection part 106, i.e., a larger force is applied to rotate the second connection part. When the resistance that the second connection part 106 receives when rotating is greater than or equal to the force applied to the second connection part 106 by other structures or the user, the hinge assembly 100 is maintained in the current state, i.e., the second connection part 106 is maintained not to move, thereby improving the stability of the hinge assembly 100.

[0190] Specifically, other structures may be connected to the second connection part 106 in addition to the hinge assembly 100, including the head 204 of the fan 200 or the upright assembly 202 of the fan 200, and the other structures may apply a force to the second connection part 106 in the rotational direction of the second connection part 106, and when the resistance that the second connection part 106 experiences due to the rotation is greater than or equal to the force that the other structures apply to the second connection part 106, the hinge assembly 100 and the other structures attached to the second connection part 106 are maintained in their current state, thereby improving the stability of the second connection part 106 and the other structures connected to the second connection part 106.

[0191] Furthermore, the hinge assembly 100 further includes a pad 1086 provided on the rotation axis 102, wherein the pad 1086 is provided between the second connection part 106 and the limiting structure, and / or the pad 1086 is provided between the first connection part 104 and the second connection part 106, and / or the pad 1086 is provided between the first connection part 104 and the fastening part 1080.

[0192] In this embodiment, a pad 1086 may be provided between the two structures to improve the stability of the connection: a pad 1086 between the second connecting part 106 and the limiting structure, and / or a pad 1086 between the second connecting part 106 and the first connecting part 104, and / or a pad 1086 between the first connecting part 104 and the clamping part 1080.

[0193] Specifically, in the axial direction of the rotation shaft 102, both ends of the pad 1086 abut against other structures, i.e., the pad 1086 can press against the structures on both sides, thereby increasing the force required for the structures on both sides of the pad 1086 to rotate, thereby improving the stability of the hinge assembly 100.

[0194] Further, the vibration damping components include any one or combination of elastic pads 1082, viscous vibration damping components, and idle gears.

[0195] In this embodiment, the vibration-damping component includes one or a combination of an elastic pad 1082, a viscous vibration-damping component, and an idle gear to improve the stability of the hinge assembly 100. Furthermore, the viscous vibration-damping component includes a vibration-damping oil.

[0196] Furthermore, a limiting surface is formed in at least a portion of the rotating shaft 102 in the axial direction of the rotating shaft 102, and a through hole is provided in the pad 1086, and the cross-sectional shape of the through hole matches the cross-sectional shape of the portion of the rotating shaft 102 where the limiting surface is provided.

[0197] In this embodiment, a limiting surface is formed on the rotating shaft 102 in the axial direction of the rotating shaft 102, and the cross-section of the through hole of the pad 1086 matches the shape of the part of the rotating shaft 102 where the limiting surface is provided, so that the pad 1086 cannot rotate on the rotating shaft 102, and further improves the stability of the hinge assembly 100.

[0198] Specifically, the portions where the rotating shaft 102 and other structures in the hinge assembly 100 are connected, except for the second connecting part 106 and the fastening part 1080, may all be provided with corresponding limiting surfaces, and the shapes of the mounting hole portions of the other structures, except for the second connecting part 106 and the fastening part 1080, that are connected to the rotating shaft 102 also match the rotating shaft 102, thereby preventing the other structures from rotating and improving the reliability of the structure.

[0199] Furthermore, the number of the limiting surfaces is at least two, and the at least two limiting surfaces are provided opposite each other in the circumferential direction of the axis of the rotating shaft 102.

[0200] In this embodiment, at least two limiting surfaces are provided opposite to each other in the circumferential direction of the axis of the rotating shaft 102, so as to improve the limiting effect of the limiting surfaces.

[0202] In this embodiment, there are at least two second connecting parts 106, which improves the connection strength between the hinge assembly 100 and the fan head 204; and the two second connecting parts 106 are disposed in the mounting grooves of the first connecting part 104, which improves the connection strength of the hinge assembly 100 and prevents the second connecting parts 106 from coming loose.

[0203] Specifically, there are two second connecting parts 106, and the two second connecting parts 106 are both located in the mounting grooves of the first connecting part 104, and the two second connecting parts 106 are restricted by the vibration damping parts, the pads 1086, and the friction plates.

[0204] Example 21: An embodiment according to the present application includes the features described in the above embodiments, and furthermore, in the axial direction of the rotation shaft 102, the second connecting part 106 is provided on one side of the first connecting part 104.

[0205] In this embodiment, the second connecting part 106 is located on one side of the first connecting part 104 in the axial direction of the rotating shaft 102, that is, the second connecting part 106 is located outside the first connecting part 104, so that the first connecting part 104 and the second connecting part 106 can be attached to the rotating shaft 102 in this order, which improves the assembly efficiency of the product and enhances the reliability of the product. At the same time, the first connecting part 104 can avoid the second connecting part 106 when the second connecting part 106 rotates, so that the second connecting part 106 has a larger rotation angle and can meet various application scenarios.

[0206] Example 22: One embodiment of the present application includes the features described in the above embodiment, and further includes a fan head 204 that further includes a motor housing having a drive shaft 116 and blades disposed therein, the motor housing having a wire passing portion 2040, the fan 200 further including a connecting wire, the wire passing portion 2040 being suitable for passing the connecting wire.

[0207] In this embodiment, the fan head 204 further includes a motor housing, in which a motor is disposed, the motor including a drive shaft 116, and the blades are connected to the drive shaft 116; however, the motor housing is provided with a wire passing portion 2040, and the fan 200 further includes a connecting line, which passes through the gap between the two second connecting parts 106 from the vertical pole assembly 202, and then is connected to the motor via the wire passing portion 2040, making the wiring more rational.

[0208] Specifically, the second connecting part 106 is attached to the motor housing.
