Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art all belong to the protection scope of the present invention.
Example 1:
as shown in fig. 1-3, the O-type oscillating mechanism described in this embodiment includes an oscillating head 1 and an oscillating driving device 2 for driving the oscillating head to oscillate, the oscillating driving device 2 includes a ball bearing, a directional oscillating member 7, a motor 10 and an eccentric connecting member 8, the eccentric connecting member is fixed on a rotating shaft of the motor, an eccentric rod 81 of the eccentric connecting member is inserted into a central shaft hole of the directional oscillating member 7, an oscillating shaft 3 of the oscillating head 1 is inserted into a ball body of the ball body and connected with the directional oscillating member 7, a plurality of limiting grooves 61 are disposed on one side surface of the ball bearing facing the directional oscillating member, a plurality of limiting rods 71 are disposed on the directional oscillating member 7, the limiting rods 71 are disposed in the limiting grooves 61, and a space exists between an outer wall of the limiting rods 71 and an inner wall of the limiting grooves 61, and the space is a space for oscillating; the swing head used in this embodiment may be a conventional fan structure (generally including an external mesh enclosure and an internal motor and fan blades, such as a household common desk fan), or a heater structure (generally including an external mesh enclosure and an internal heating structure), or a ceiling fan (i.e., a fan hung on a roof or a wall, and having a structure similar to a household desk fan), or an air circulation fan (which is similar to a fan but has a main structure including a driving motor, a turbofan, and a flow guide grille).
When the motor 10 operates, the eccentric connecting piece is driven to rotate, the eccentric rod 81 is inclined as shown in fig. 2, so that when the eccentric connecting piece rotates, the eccentric rod 81 obliquely acts on a central shaft hole of the direction swinging piece 7 to show the swinging of the direction swinging piece 7, and because the direction swinging piece 7 is not always in a vertical state in fig. 2 during swinging, the direction swinging piece can also incline, and at the moment, the distance is reserved between the limiting rod 71 and the limiting groove 61, so that the swinging can be ensured to be smoothly carried out; because of the limitation of the limiting groove 61, the whole swing of the direction swinging piece is limited in the limiting groove, so the swinging state is stable, and the swinging angle is relatively stable, therefore, compared with the traditional fan which directly swings under the direct drive of an eccentric rod, the swinging angle of the fan is increased to a certain degree, and the swinging angle of the fan can be always kept at the maximum angle limited by the limiting groove 61; compared with the left-right swinging of the traditional fan, the swinging takes the ball bearing as a fulcrum during swinging, and the connecting end of the swinging shaft lever and the swinging head part walks out of an O-shaped swinging track, namely a circular motion track (similar to a conical swing) during swinging, as shown in figure 4, the dotted line part is the swinging track, so that the swinging head part swings along with the O-shaped swinging track, and a larger swinging head angle is provided, and the air supply angle is larger; the motor drives the eccentric rod 81 to swing according to the principle that the motor drives the eccentric wheel to perform eccentric motion in the prior art, and the embodiment improves the stability and the swing angle on the basis.
As shown in fig. 2 and 3, the ball bearing in this embodiment includes a bearing front end cover 4 and a bearing rear end cover 6, the bearing front end cover 4 and the bearing rear end cover 6 are relatively fixed, and a spherical hole is formed by splicing the two, and the ball 5 is installed in the spherical hole, so that the ball 5 can swing in the spherical hole;
at this time, the limiting grooves 61 are formed in the bearing rear end cover 6 (shown in fig. 3), the limiting grooves are four in the bearing rear end cover 6, the limiting rods 71 are correspondingly four in the limiting rods 71 (shown in fig. 2), the back face of the bearing rear end cover 6 in fig. 2 is an inner cavity of the bearing rear end cover, most of the direction swinging pieces 7 are located in the inner cavity when the limiting rods 71 and the limiting grooves are limited, the direction swinging pieces 7 do not rotate when swinging, and only the swinging shaft rod is driven to swing by taking the position of the ball 5 as a fulcrum, so that a space is reserved between the limiting rods 71 and the limiting grooves 61, and the swinging is performed.
The swing driving device 2 of the embodiment further comprises a front panel 21, the bearing front end cover 4 is fixedly arranged in an inner cavity of the front panel 21, and the bearing rear end cover 6 and the bearing front end cover 4 are fixed through screws; the back of the front panel 21 is provided with a bottom plate 11, a motor fixing plate 9 is fixedly arranged on the bottom plate 11, and a motor 10 is fixedly arranged on the fixing plate 9; the output shaft 101 of the motor 10 penetrates through the motor fixing plate 9, the eccentric connecting piece 8 comprises a transmission groove, the tail end of the output shaft 101 is connected with the transmission groove in a matching mode, the transmission groove only needs to enable the output shaft 101 to successfully drive the eccentric connecting piece 8 to rotate, for example, the transmission groove is square, the end face of the eccentric connecting piece 8 abuts against the motor fixing plate 9, the structure is shown in fig. 2, after installation, the structure can be seen in fig. 3, the eccentric connecting piece 8 in fig. 3 is not shown, and an eccentric rod of the eccentric connecting piece 8 is connected with a shaft hole on the right side of the direction swinging piece 7 in fig. 3.
The present embodiment proposes two preferred ways of connecting the directional swing member to the rocker shaft: the direction swinging piece 7 comprises a middle shaft at the middle part, wherein the first mode is that the middle shaft is connected with a swinging shaft rod in a sleeved mode; the second is that fastening meets through setting up screw and screw between axis and the axostylus axostyle of shaking the head, and two kinds of connected modes can all guarantee to sway the head and stably shake the head.
As shown in fig. 1, the left side of the oscillating shaft lever 3 is fixedly provided with a positioning plate, the positioning plate and the oscillating head are provided with corresponding thread fixing holes, the positioning plate and the oscillating head are fixed through screws, and the oscillating head 1 and the oscillating shaft lever 3 are more stably installed after the positioning plate is installed.
In the embodiment, when the motor 10 operates, the eccentric connecting piece is driven to rotate, the eccentric rod 81 obliquely acts on the central shaft hole of the direction swinging piece 7 when the eccentric connecting piece rotates, namely, the swinging of the direction swinging piece 7 is shown, due to the limitation of the limiting groove 61, the overall swinging of the direction swinging piece is limited in the limiting groove, and compared with the traditional fan (or a heater and the like), the swinging angle of the fan can be always kept at the maximum angle limited by the limiting groove 61 because the eccentric rod directly drives the swinging to increase certain stability.
The present invention is not limited to the above-mentioned preferred embodiments, and any other products in various forms can be obtained by the teaching of the present invention, but any changes in the shape or structure thereof, which have the same or similar technical solutions as the present invention, fall within the protection scope of the present invention.
