Example 1
Fig. 1 to 7 show a moving head mechanism of a fan provided for this embodiment, including: a base 1; the rotating assembly 2 is rotatably arranged on the base 1, and the rotating assembly 2 comprises a connecting piece 21 arranged on the fan body; the rolling component 22 is arranged on the connecting piece 21, and the rolling end of the rolling component is embedded on the base 1; and the driving assembly 3 is arranged on the base 1 and/or the rotating assembly 2 to drive the rotating assembly 2 to rotate.
The oscillating structure of the fan in this embodiment is installed between the body of the fan and the chassis, so that the body of the fan can rotate on the chassis.
It should be noted that the base 1 is generally fixedly connected with a chassis of the fan, the rotating assembly 2 is fixed on the fan body through a connecting member 21, a rolling end of the rolling assembly 22 is embedded on the base 1 to roll on the base 1, and when the driving assembly 3 drives the rotating assembly 2, the fan body can rotate on the base 1 under the action of the rolling assembly 22. In the rotating assembly 2 adopted in this embodiment, the rolling assembly 22 is adopted to realize the movable connection between the fan body and the base 1, the rolling assembly 22 realizes the supporting effect on the fan body in the height direction of the fan body, the supporting points of general rolling supports are all set to be multiple, the supporting stability is good, in addition, in the radial direction of the fan body, the rolling assembly 22 is arranged on the base 1 in an embedded mode, the radial constraint on the rolling assembly 22 is realized, and the stability in the rotating process is further ensured.
Furthermore, the implementation objects of the fan oscillating structure in this embodiment are mostly tower fans or bladeless fans, and the main body thereof is mostly cylindrical, so the overall shape of the fan oscillating structure in this embodiment is disc-shaped and is matched with the main body, so as to ensure the aesthetic property of the overall structure of the fan.
In this embodiment, before the integral assembly, the rotating assembly 2 needs to be preassembled, and the rotating assembly 2 is explained as follows:
as described above, the rotating assembly 2 includes the rolling assembly 22 therein, and when the rotating assembly 2 is assembled, the rolling assembly 22 is assembled, wherein the rolling assembly 22 includes: the holder 221 is formed with a plurality of card slots 2211, ten in the present embodiment, and as shown in fig. 5 and 6, the card slots 2211 are through slots. In other embodiments, the number of the support members may be other, and the larger the number is, the better the support effect is. The balls 222, and a part of the balls 222 are movably installed in the slot 2211, and the use of the balls 222 can reduce the friction resistance and noise when the fan body rotates.
In other embodiments, the balls 222 in the rolling assembly 22 may be replaced by a roller structure, and the shaft ends of the roller are mounted on the holder 221 in a manner similar to the conventional roller mounting manner, which is not described herein again.
Further, the aforementioned card slot 2211 has a circular slot and at least one pair of elastic limiting pieces oppositely disposed on the inner wall of the slot, in this embodiment, as shown in fig. 5 and fig. 6, on the inner wall of the card slot 2211, two elastic limiting pieces 2212 are mounted on one surface along the circumferential direction of the entire holder 221, and two elastic limiting pieces 2212 are also mounted on the other surface along the radial direction of the holder 221, the four elastic limiting pieces 2212 form a ball 222 clamping space arranged in a cross shape, the ball 222 is rotatably clamped between the four elastic limiting pieces, when the ball 222 is actually mounted, it is very easy to fall off from the card slot 2211, and the movement and the combined mounting with other components are laborious, so that a corresponding mounting jig needs to be designed, which is time and labor consuming, and the design of the elastic limiting pieces effectively simplifies the mounting of the ball 222.
In other embodiments, the number of the elastic stoppers 2212 may be six, eight, etc., which is more effective for clamping the balls 222.
In other embodiments, the number of the elastic stoppers may be an odd number, such as three, and the ball 222 may be clamped.
In other embodiments, the elastic stoppers 2212 may be disposed on only one side of the holder 221, and the number of the stoppers is similar to that of the stoppers disposed on both sides.
The retainer 221 in this embodiment is annular, and the above-mentioned slots 2211 are distributed at equal intervals along the circumferential direction, so that the bearing force of each ball 222 arranged thereon is basically the same, and the situation that a part of the balls 222 is stressed too much due to uneven component force and is damaged in advance does not occur, thereby further ensuring the stability of the support.
In the present embodiment, the connecting member 21 is mostly an injection molded part, and the strength is low, and if the ball 222 directly abuts on the connecting member 21, the abutting position of the connecting member 21 is deformed over time, which easily causes the ball 222 to roll unsmoothly, and generate noise, and so on, and therefore the rolling assembly 22 in the present embodiment includes the collar 223, and the retainer 221 is mounted on the lower end surface of the collar 223.
Further, the gasket 223 is formed with a surrounding ring toward the center of the gasket 223, and the holder 221 is fitted in the surrounding ring with a clearance fit. In the actual rotating process, the balls 222 may be intermittently jammed in an abnormal state in the using process, and the retainer 221 which is installed in the enclosure in a clearance fit manner can automatically slide in the enclosure when the balls 222 are jammed, so that the work of the fan oscillating mechanism is not influenced.
Of course, while ensuring that the balls 222 rotate well in the slots 2211, in some other embodiments, the cage 221 may also be inserted into the enclosure in an interference fit.
Since the ring 223 does not need to rotate in the actual rotation process, a stop structure is formed on the outer circumferential surface of the surrounding ring, the stop structure is a small convex edge protruding out of the outer circumferential surface, and when the ring is installed, the convex edge structure is embedded into the installation groove on the connecting piece 21 to prevent the ring from rotating.
As shown in fig. 7, since the fan body has a considerable height, in order to reduce the radial stress at the clamping position of the rolling assembly 22 and the base 1 and ensure the service life of the rolling assembly 22, in this embodiment, a limiting ring 23 is further designed to be installed around the base 1, one end of the limiting ring 23 is installed on the connecting piece 21, the other end is movably clamped on the base 1, the limiting ring 23 is protected in the circumferential direction of the rolling assembly 22, and part of the limiting ring is movably clamped and covered on the base 1 to reduce the shaking of the fan body relative to the outer periphery of the base during the rotation process.
The clamping mode is as follows, the lower end face edge of the limiting ring 23 is provided with a flange 231 formed towards the center of the limiting ring 23, a convex edge 11 is formed outwards along the circumferential direction of the base 1, and the flange 231 is clamped below the convex edge 11. The up-and-down arrangement of the flanges 231 and the flanges 11 realizes the restraint on the height direction of the machine body, and in the circumferential direction, the whole flange 231 structure realizes the partial coating of the flanges 11 and restrains the radial movement of the flanges.
In order to fix the limiting ring 23, three hooks 232 are formed at the upper end face of the limiting ring 23, hook grooves 212 are formed in the connecting piece 21 corresponding to the hooks 232, when the limiting ring is installed, the hooks 232 can be clamped in the hook grooves by rotating the limiting ring, and the installation is simple and rapid.
Of course, in other embodiments, the hook 232 may also be formed on the connecting member 21, and the slot may be formed on the stop collar 23.
In order to further restrain the radial play, annular grooves 211 matched with the collars 223 are formed at the lower end face of the connecting member 21 and the upper end face of the base 1, and the collars 223 are clamped in the annular grooves of the connecting member 21.
Of course, in order to ensure smooth rotation of the rotating assembly 2, the portion of the balls 222 protruding out of the cage 221 abuts on the groove bottom of the annular groove of the base 1.
Briefly described below with respect to the drive assembly 3, as shown in fig. 1, the drive assembly 3 comprises: a motor 31 installed on a lower end surface of the connection member 21; a driving gear 32 installed on a motor shaft of the motor 31 in a flat key manner; and a driven gear 33 provided on the base 1 to be engaged with the driving gear 32, as shown in fig. 3, wherein the driven gear 33 is a ring gear formed on an inner side wall of the base 1.
In other embodiments, the above-mentioned gear ring may also be an external gear ring, and it is sufficient that the basic transmission of the gear is realized.
