As shown in fig. 1 to 4, according to the embodiment of the present invention, an oscillating motor rotation structure includes a base 100, a rotating disc 200, a first ball 310, a first driving member 500 and a second driving member 600, wherein the first driving member 500 is installed on the base 100 and used for driving the rotating disc 200 to rotate, the second driving member 600 is installed on one side of the rotating disc 200 departing from the first driving member 500, and a driving shaft center line of the second driving member 600 is obliquely arranged with a rotation axis of the rotating disc 200, so that the first driving member 500 is matched with the second driving member 600, a driving shaft of the second driving member 600 performs a circumferential rocking motion and a rotating motion, which can be applied as a power element of an oscillating fan, optionally, the rotating disc 200 is disc-shaped, and the rotation axis of the rotating disc 200 coincides with the center line of the rotating disc 200. Specifically, the first ball 310 is disposed between the base 100 and the rotating disk 200, one end of the first ball 310 abuts against the base 100, and the other end abuts against the rotating disk 200, and one of the rotating disk 200 and the base 100 is provided with a first annular groove 210, and the other is provided with a first stopper protrusion 110 fitted with the first annular groove 210, and the center line of the first annular groove 210 coincides with the rotation axis of the rotating disk 200. It should be noted that the first driving member 500 and the second driving member 600 are respectively installed on two sides of the rotary disc 200, and the rotary disc 200 is connected with the base 100 through the first ball 310, so that friction between the rotary disc 200 and the base 100 when the first driving member 500 drives the rotary disc 200 to rotate is reduced, operation is more stable and noise is lower, and the first annular groove 210 is matched with the first limiting protrusion 110 to guide rotation of the rotary disc 200, thereby further improving stability of rotation of the rotary disc 200.
In fig. 1 and 2, the surface contact between the base 100 and the rotating disk 200 after the first balls 310 are mounted is merely illustrated, and a gap is left between the facing surfaces of the base 100 and the rotating disk 200 in the rotation axis direction of the rotating disk 200 after the first balls 310 are actually mounted. For example, the rotary disk 200 and the base 100 are each provided with a mounting groove (not shown) for mounting the first ball 310, the mounting groove extending around the rotation axis of the rotary disk 200 and forming a closed loop, and the height of the mounting groove in the direction of the rotation axis of the rotary disk 200 is less than half the diameter of the first ball 310, so that a gap is left between the base 100 and the rotary disk 200 after both ends of the first ball 310 are mounted in the mounting groove of the base 100 and the mounting groove of the rotary disk 200, respectively. At this time, the first ball 310 slides in the mounting groove. For another example, referring to fig. 3 and 4, the rotating disc 200 is uniformly provided with a plurality of ball grooves for mounting the first balls 310 along the circumferential direction, the contact surface between the base 100 and the first balls 310 is a plane, and a gap is also left between the base 100 and the rotating disc 200, and at this time, the first balls 310 are mounted in the ball grooves of the rotating disc 200.
In some embodiments, the first annular groove 210 is disposed on the rotating disc 200, the first limiting protrusion 110 is disposed on the base 100, the base 100 is provided with the oil filling groove 120, the oil filling groove 120 is used for adding lubricating oil to the first ball 310, and the friction generated when the first ball 310 rotates after being added with lubricating oil is smaller, so that the friction generated when the rotating disc 200 rotates relative to the base 100 is further reduced. Optionally, the first rolling ball 310 is made of stainless steel to avoid rusting. Specifically, first spacing arch 110 extends along the circumference of first ring channel 210, and first spacing arch 110 has a plurality ofly, and a plurality of first spacing archs 110 are arranged along the circumference interval of first ring channel 210, forms oiling groove 120 between the adjacent first spacing arch 110, and simple structure, oiling groove 120 is close with first ball 310's distance, and a small amount of additional lubricating oil can make it flow to first ball 310, and the result of use of lubricating oil is higher. In some embodiments, a portion of the first ball 310 extends into the oil sump 120, further improving the application of the lubricant to the first ball 310. For example, the first balls 310 are mounted on the rotating disk 200, the first balls 310 rotate together with the rotating disk 200, and when the first balls 310 rotate to the oil filling groove 120, less than half of the first balls 310 extend into the oil filling groove 120, that is, the center of the first balls 310 is located on the side of the oil filling groove 120 away from the center of the rotating disk 200, and the first balls 310 cannot fall out of the oil filling groove 120.
Optionally, the end of the first limiting protrusion 110 is an arc-shaped structure, and the first limiting protrusion 110 can be conveniently inserted into the first annular groove 210 and is in rotating fit with the first annular groove 210.
Further, a housing 400 is coupled to the base 100, and the housing 400 is used to shield the rotary disk 200. In one aspect, the housing 400 is used to shield the rotating disk 200 of the movable portion from being exposed. On the other hand, since the housing 400 and the base 100 are stationary relative to the rotating disc 200, and when the second driving member 600 adopts an outer rotor motor structure, it is more convenient for a person to hold the side of the second driving member 600.
In order to prevent the housing 400 from being directly disposed outside the rotary disk 200, the housing 400 is not coupled to the rotary disk 200, resulting in poor rigidity. In some embodiments, the second ball 320 is disposed on a side of the rotating disc 200 facing away from the first ball 310, one end of the second ball 320 abuts against the rotating disc 200, and the other end abuts against the housing 400, so that the structure is more compact, and both ends of the rotating disc 200 pass through the balls to reduce friction generated during rotation, and the operation is more stable. Similar to the first annular groove 210 and the first limit projection 110, one of the rotating disc 200 and the outer case 400 is provided with a second annular groove 220, and the other one is provided with a second limit projection 410 engaged with the second annular groove 220, and a center line of the second annular groove 220 coincides with a center line of the first annular groove 210 to guide the rotation of the rotating disc 200, thereby further improving the stability of the rotation of the rotating disc 200, for example, the second annular groove 220 is provided in the rotating disc 200, and the second limit projection 410 is provided in the outer case 400. In some embodiments, there are two second annular grooves 220 and two second limiting protrusions 410, and the two second annular grooves 220 are concentrically arranged and have successively larger diameters. The second limiting protrusions 410 correspond to the second annular grooves 220 one to one, and the second balls 320 are located between the two second annular grooves 220. The second annular groove 220 and the second limiting protrusion 410 form guide matching, and two sides of the second ball 320 are respectively matched in a guide way, so that the deflection phenomenon caused when the shell 400 is connected with the rotating disc 200 through the second ball 320 when only one guide matching is arranged is effectively avoided, and the operation stability is further improved. Alternatively, the second stopper protrusion 410 may have an arc-shaped end portion, similar to the first stopper protrusion 110. The second stopper protrusion 410 can be easily inserted into the second annular groove 220 and is rotatably fitted into the second annular groove 220.
It should be noted that, referring to fig. 3 and 4, both sides of the rotating disc 200 are respectively provided with a ball groove for mounting the first ball 310 and a ball groove for mounting the second ball 320, and the ball grooves are provided in plurality and uniformly arranged along the circumferential direction of the rotating disc 200. The first ball 310, the second ball 320 and the rotating disk 200 rotate together, and the first ball 310 and the second ball 320 rotate freely in the ball grooves, respectively. Correspondingly, the contact surface between the base 100 and the first ball 310 is a plane, and the contact surface between the housing 400 and the second ball 320 is a plane. Additionally, referring again to fig. 5 and 6, in some embodiments, the base 100 is provided with a first ball slot 130 for mounting the first ball 310 and the housing 400 is provided with a second ball slot 420 for mounting the second ball 320. The first ball 310 is mounted in the first ball groove 130 and freely rotates in the first ball groove 130, and a contact surface between the rotating disc 200 and the first ball 310 is a flat surface. The second ball 320 is mounted in the second ball groove 420 and freely rotates in the second ball groove 420, and a contact surface between the housing 400 and the second ball 320 is a flat surface.
