As shown in fig. 1 and fig. 2, the oscillating mechanism 100 includes a base 10, a pressing plate 30 and a support 50 capable of rotating around a rotation axis relative to the base 10, the base 10 is fixedly connected to a supporting chassis of the tower fan, the support 50 is fixedly connected to a main body of the electrical equipment, and the main body can rotate synchronously with the support 50 to realize the oscillating and sweeping functions of the tower fan.
As shown in fig. 1, 2 and 3, specifically, the base 10 includes a base main body 12 and a base stopper 14. The base body 12 is a substantially circular-cross-section rotor-like structure, and includes a base bottom wall 121, a base side wall 123, and base support legs 125 that are integrally formed. The cross section of the base bottom wall 121 is circular, a bearing surface 1212 for bearing the bracket 50 is formed on an end surface of one side of the base bottom wall 121, a shaft hole 1214 communicating with the bearing surface 1212 is formed in the center of the base bottom wall 121, and the shaft hole 1214 is used for being coupled with the bracket 50. The base sidewall 123 extends from an edge of the base bottom wall 121 in a direction away from the bearing surface 1212 and circumferentially surrounds the base bottom wall 121. The base support legs 125 are circumferentially spaced from the base sidewall 123, and each base support leg 125 extends in a direction away from the bearing surface 1212 until extending beyond the base sidewall 123 to connect to the support chassis. The base stoppers 14 are circumferentially spaced at the edge of the base bottom wall 121, and each base stopper 14 protrudes out of the bearing surface 1212 in the axial direction of the base 10 to mate with the pressing plate 30.
As shown in fig. 1, 2, and 4, the platen 30 includes a platen main body 32 and a platen stopper 34. The pressing plate main body 32 is substantially annular, the outer diameter of the pressing plate main body 32 is substantially equal to the outer diameter of the base bottom wall 121, and the plurality of pressing plate limit parts 34 are circumferentially arranged at the edge of the pressing plate main body 32 at intervals. When the pressing plate 30 is coupled to one side of the base 10 having the bearing surface 1212, the pressing plate limiting part 34 abuts against the base limiting part 14 in the direction of the rotation axis of the bracket 50, the pressing plate main body 32 and the base main body 12 are disposed at an interval, a limiting gap for limiting the bracket 50 is defined between the pressing plate main body 32 and the bearing surface 1212 of the base main body 12, and the limiting gap extends along the edge circumference of the bearing surface 1212 because the pressing plate main body 32 is in a ring-shaped structure with an outer diameter substantially equal to the base bottom wall 121.
Specifically, in some embodiments, each of the base position-limiting members 14 includes a base supporting portion 141 and a base engaging portion 143, the base supporting portion 141 extends along the circumferential direction of the base main body 12 and is curved into an arc shape, the base engaging portion 143 is connected to one end of the base supporting portion 141 in the extending direction and is located on one side of the base supporting portion 141 away from the base bottom wall 121, and the thickness of the base engaging portion 143 in the rotation axis direction of the bracket 50 is smaller than that of the base supporting portion 141 in the rotation axis direction of the bracket 50. Each of the pressure plate limiting members 34 includes a pressure plate supporting portion 341 and a pressure plate buckling portion 343, the pressure plate supporting portion 341 extends along the circumferential direction of the pressure plate main body 32 and is curved into an arc shape, the pressure plate buckling portion 343 is connected to one end of the pressure plate supporting portion 341 in the extending direction, and the pressure plate supporting portion 341 and the pressure plate buckling portion 343 are disposed at two opposite ends of the pressure plate limiting member 34 at intervals in the rotation axis direction of the bracket 50.
When the pressing plate 30 is mounted on the side of the base 10 having the carrying surface 1212, the pressing plate supporting portion 341 is partially abutted against the upper end surface of the side of the base supporting portion 141 away from the carrying surface 1212, and then the pressing plate 30 is rotated along the circumferential direction of the base 10 to screw the pressing plate engaging portion 343 into the lower portion of the base engaging portion 143. Thus, the pressing plate supporting portion 341 is partially supported on the upper end surface of the side of the base supporting portion 141 away from the carrying surface 1212, and the pressing plate engaging portion 343 abuts against the lower end surface of the base engaging portion 143 facing the carrying surface 1212. Therefore, the pressing plate supporting portion 341 and the pressing plate engaging portion 343 are respectively abutted against opposite sides of the base limiting member 1434 in the rotation axis direction of the bracket 50, and the pressing plate 30 is fixed in the rotation axis direction of the bracket 50 relative to the base 10.
Furthermore, each base supporting portion 141 of the base position-limiting member 14 further has at least one first connection hole 1412, each pressing plate supporting portion 341 of the pressing plate position-limiting member 34 has a second connection hole 3412 correspondingly connected to the first connection hole 1412, and the head moving mechanism 100 further includes a connection member inserted into the first connection hole 1412 and the second connection hole 3412 along the rotation axis direction of the bracket 50. In this way, the base 10 and the pressing plate 30 are limited in the circumferential direction by the connecting member, so that the pressing plate engaging portion 343 and the base engaging portion 143 are prevented from being separated due to the relative rotation of the base 10 and the pressing plate 30. Preferably, in one embodiment, the first connection hole 1412 and the second connection hole 3412 are both threaded holes, and the connector is a screw matched with the threaded hole.
Specifically, in some embodiments, the base 10 includes four base position-limiting members 14, the pressing plate 30 includes four pressing plate position-limiting members 34, and each base position-limiting member 14 is coupled to one pressing plate position-limiting member 34. It can be understood that the number of the base position-limiting elements 14 and the pressure plate position-limiting elements 34 is not limited thereto, and different numbers of the base position-limiting elements 14 and the pressure plate position-limiting elements 34 can be set as required to meet different requirements.
As shown in fig. 1, 2 and 5, the bracket 50 includes a bracket main body 52, a rotation shaft 54 and a flange 56 which are integrally formed. The bracket main body 52 is a substantially circular-cross-section solid of revolution, the cylindrical rotating shaft 54 is convexly disposed in the middle of one side end face of the bracket main body 52 facing the base 10, the flange 56 circumferentially surrounds one end of the bracket main body 52 close to the base 10, and the outer diameter of the flange 56 is not greater than the outer diameter of the base bottom wall 121.
When the bracket 50 is mounted on the base 10, the shaft 54 is inserted into the shaft hole 1214 through the shaft sleeve 70, so that the bracket 50 can rotate relative to the base 10 with the shaft 54 as a rotation center. Meanwhile, the pressing plate 30 is sleeved outside the bracket body 52, the flange 56 surrounding the bracket body 52 is limited in a limiting gap defined between the pressing plate 30 and the base 10, and two end surfaces of the flange 56 in the axial direction respectively abut against the bearing surface 1212 of the base bottom wall 12 and the pressing plate body 32, so that the bracket 50 is firmly limited on the base 10 in the direction of the rotation axis.
In this way, the bracket 50 is rotatably limited on the base 10 in the radial direction by integrally providing the rotating shaft 54 with the bracket main body 52, and there is no need to additionally provide a sheet metal shaft to connect the bracket 50 and the base 10. Moreover, because the edge of the bracket 50 is limited in the limit gap, the bracket 50 and the base 10 have larger axial limit diameters, thereby effectively reducing the shaking amount of the main body relative to the supporting chassis.
It is understood that in other embodiments, the shaft hole 1214 may be opened on the bracket body 52, the shaft 54 protrudes on the bearing surface 1212 of the base 10, and the shaft 54 is rotatably inserted in the shaft hole 1214.
Referring to fig. 1 and fig. 2, further, the oscillating mechanism 100 further includes a power assembly 90, wherein the power assembly 90 is mounted on the bracket 50 and is connected to the base 10 in a transmission manner, and is used for driving the bracket 50 to rotate relative to the base 10, so as to realize the oscillating function of the oscillating mechanism 100.
Specifically, the power assembly 90 includes a driving unit 92 and a transmission unit 94, the driving unit 92 is fixedly connected to the bracket 50, the driving unit 92 is in transmission connection with the base 10 through the transmission unit 94, and the driving unit 92 drives the base 10 and the bracket 50 to move relatively through the transmission unit 94. Since the base 10 is fixed to the support chassis in a stationary state, the stand 50 rotates relative to the rotating base 10.
Specifically, in some embodiments, the drive unit 92 is an electric motor having an output shaft 921 for outputting torque. The bracket main body 52 is provided with an arc-shaped slot 521 in a penetrating manner, and the circle center of the arc-shaped slot 521 coincides with the circle of the shaft hole 1214. The bearing surface 1212 of the bottom wall 121 of the base 10 is provided with a cylindrical rocker 1216 positioned at one side of the axial hole 1214, and one end of the cylindrical rocker 1216 away from the bearing surface 1212 extends into the arc-shaped groove 521 of the bracket main body 52. The transmission unit 94 includes a crank 941 and a connecting rod 943, one end of the crank 941 is fixed to the output shaft 921 of the driving unit 92, the other end of the crank 941 is rotatably connected to one end of the connecting rod 943, the other end of the connecting rod 943, which is not connected to the crank 941, is rotatably connected to the rocker 1216, and the rocker 1216 can slide back and forth along the arc-shaped slot 521.
Thus, when the output shaft 921 of the driving unit 92 rotates, the crank 941 rotates around the output shaft 921 as the rotation center under the driving of the output shaft 921, and the connecting rod 943 connected to the other end of the crank 941 is limited to the connecting rocker 1216 and can only rotate around the connecting rocker 1216, and the bracket 50 is connected to the connecting rocker 1216 through the arc-shaped slot 521, so that the crank 941 drives the bracket 50 to rotate relative to the base 10 through the driving unit 92, thereby realizing the shaking function of the shaking mechanism 100. It is to be understood that the specific configuration of the transmission unit 94 is not limited thereto, and may be set as needed to meet various requirements.
In the head shaking mechanism 100 and the electrical equipment provided with the head shaking mechanism 100, the rotating shaft 54 integrally arranged with the bracket main body 52 is directly inserted into the shaft hole 1214 of the base 10 so as to be rotatably connected with the shaft hole 1214, and an additional sheet metal shaft is not required to be arranged to connect the bracket main body 52 with the base 10, so that the number of parts is simplified. Moreover, the edge of the bracket 50 is axially limited in the limit gap formed by the base 10 and the pressing plate 30, so that the axial limit diameter of the bracket 50 and the base 10 is enlarged, the main body of the electrical equipment is effectively prevented from shaking relative to the supporting chassis, and the stability of the electrical equipment in the use process is improved.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
