[0027] like Figure 1-Figure 5As shown, in an embodiment of the utility model, a three-dimensional swinging device is provided, including a driving mechanism 10, a bracket 20, an eccentric chain rod 30, a movable chain rod 40 and a rocking arm 50. The bracket 20 is arranged on the driving mechanism 10, and a swingable rocking arm 50 is arranged on the bracket 20. The driving mechanism 10 is provided with a rotating shaft 110, the eccentric chain rod 30 is fixedly arranged on the rotating shaft 110, the eccentric chain rod 30 is provided with a limiting hole 310, the swingable rocking arm 50 is provided with a sliding shaft 510, and the movable chain rod 40 is slidably connected to the sliding shaft 510 at one end close to the swingable rocking arm 50, and the other end of the movable chain rod 40 makes repeated movements in the limiting hole 310, and the other end of the movable chain rod 40 is parallel to the rotating shaft 110. For example, the driving mechanism 10 includes a motor 120 and a reduction box 130. The reduction box 130 is arranged on the motor 120, the rotating shaft 110 is arranged on the reduction box 130, and the motor 120 is provided with a transmission shaft. The motor 120 drives the rotating shaft 110 on the reduction box 130 to rotate through the transmission shaft. The transmission cooperation between the motor 120 and the reduction box 130 is the existing technology and will not be described in detail here. The reduction box 130 is provided with two symmetrical threaded holes 131, and the bracket 20 is correspondingly provided with two nut holes 210. The two nut holes 210 and the two threaded holes 131 are fixed by inserting screws. The method of fixing by screws can also be replaced by fixing methods such as bolts. By setting screws or bolts and other fixing parts on the bracket 20 and the reduction box 130, it is convenient to stably fix the bracket 20 on the reduction box 130. The reduction box 130 is provided with a connecting block 132 around the rotating shaft 110, and the bracket 20 is provided with a connecting groove 220. The connecting block 132 is embedded and fixed on the connecting groove 220. The rotating shaft 110 is arranged at the center position of the connecting block 132, and the rotating shaft 110 passes through the connecting groove 220 and is inserted into the eccentric chain rod 30. The connecting block 132 can also be a rectangular block, and the connecting groove 220 is a rectangular connecting groove 220, so that the rectangular block can be stably stuck in the connecting groove 220.
[0028] The three-dimensional swing device provided by the utility model comprises a bracket 20 arranged on a driving mechanism 10, a swingable swinging rod 50 arranged on the bracket 20, a rotating shaft 110 arranged on the driving mechanism 10, an eccentric chain rod 30 fixedly arranged on the rotating shaft 110, a limiting hole 310 arranged on the eccentric chain rod 30, a sliding shaft 510 arranged on the swingable swinging rod 50, an end of the movable chain rod 40 close to the swinging rod 50 is slidably connected with the sliding shaft 510, the other end of the movable chain rod 40 makes repeated movements in the limiting hole 310, and the other end of the movable chain rod 40 is parallel to the rotating shaft 110. The driving mechanism 10 drives the rotating shaft 110 to rotate, thereby driving the eccentric chain rod 30 to move, so that the eccentric chain rod 30 drives the movable chain rod 40 to slide back and forth on the sliding shaft 510 through the limiting hole 310, and then drives the rocking arm 50 to swing, thereby replacing the traditional rocking device with clearance fit through the multi-dimensional sliding fit between the eccentric chain rod 30, the movable chain rod 40, the sliding shaft 510, the bracket shaft 231 and the rocking arm 50, and finally drives the rocking arm 50 to achieve precise rocking motion, avoiding the problem of inaccurate rocking angle of the traditional rocking device. Due to the traditional eccentric wheel structure, the rocking arm will generate a large noise when it moves, while the present solution drives the movable chain rod 40 to slide back and forth on the sliding shaft 510 through the limiting hole 310 through the eccentric chain rod 30, driving the rocking arm 50 to move, avoiding the noise similar to that generated by the traditional eccentric wheel structure in the process, and improving the user's comfort.
[0029] like Figure 6 As shown, in a preferred embodiment, the eccentric chain rod 30 is provided with a first fixing hole 320, and the rotating shaft 110 is inserted into the first fixing hole 320. The rotating shaft 110 is fixed in the first fixing hole 320. For example, it is an incomplete cylinder with an arc block cut in the vertical direction, and the first fixing hole 320 is an incomplete circular hole compatible with the rotating shaft 110. The rotating shaft 110 is inserted into the incomplete circular hole to prevent the eccentric chain rod 30 from loosening when the rotating shaft 110 rotates. The first fixing hole 320 can also be a rectangular hole, and the rotating shaft 110 inserted into the first fixing hole 320 is a rectangular column compatible with the first fixing hole 320. The rectangular column is inserted into the rectangular first fixing hole 320 to facilitate the eccentric chain rod 30 to be stably fixed on the rotating shaft 110. For example, a clamping block can also be provided on the rotating shaft 110, and a clamping slot is provided in the first fixing hole 320. The clamping block is provided on the clamping slot to facilitate the prevention of the eccentric chain rod 30 from loosening when the rotating shaft 110 rotates.
[0030] In a preferred embodiment, the first fixing hole 320 and the limiting hole 310 are spaced apart. For example, the center line of the first fixing hole 320 and the center line of the limiting hole 310 are parallel to each other, and the torque of the rotating shaft 110 is transmitted to the eccentric chain rod 30 .
[0031] like Figure 7As shown, in a preferred embodiment, the movable link 40 is provided with a collar 410, and the collar 410 is slidably connected with the sliding shaft 510. For example, the sliding shaft 510 adopts a cylindrical structure, which facilitates the collar 410 to slide on the sliding shaft 510.
[0032] like Figure 2 , Figure 6 and Figure 7 As shown, in a preferred embodiment, the movable chain rod 40 is provided with a conduction shaft 420, and the conduction shaft 420 is located in the limiting hole 310. The conduction shaft 420 is cylindrical, polygonal or cuboid. For example, the conduction shaft 420 of the movable chain rod 40 is inserted into the through hole of the eccentric chain rod 30, and the collar 410 at the other end slides back and forth on the sliding shaft 510, so that the movable chain rod 40 is driven not only to move back and forth on the sliding shaft 510 through the movement of the eccentric chain rod 30, but also to drive the conduction shaft 420 to move repeatedly in the through hole by driving the swinging of the rocking rod 50. A limit block is arranged outside the eccentric chain rod 30 at one end of the conduction shaft 420 close to the driving mechanism 10, so as to prevent the conduction shaft 420 from being separated from the eccentric chain rod 30 when it moves repeatedly in the eccentric chain rod 30. A metal ring is arranged inside the limiting hole 310, and the metal ring can be detachable or fixed. The metal ring reduces friction damage of the transmission shaft 420 when it moves repeatedly, and at the same time, the force of the transmission shaft 420 is evenly transmitted to prevent the weaker part of the outer side of the movable chain rod 40 from being torn. For another example, the outer side of the movable chain rod 40 is provided with reinforcing ribs to enhance the structural stability and extend the service life of the movable chain rod 40.
[0033] like Figure 1 and Figure 2 As shown, in a preferred embodiment, two support plates 230 are provided on the bracket 20, a bracket shaft 231 is provided between the two support plates 230, and a swingable rocking arm 50 is provided on the bracket shaft 231. The two support plates 230 are symmetrically arranged, and the second fixing holes 232 and the third fixing holes 233 are provided at corresponding positions of the two support plates 230, and the two ends of the bracket shaft 231 are respectively inserted into the second fixing holes 232 and the third fixing holes 233. For example, the second fixing holes 232 and the third fixing holes 233 are circular holes, which facilitates the bracket shaft 231 to be arranged on the second fixing holes 232 and the third fixing holes 233, and the swingable rocking arm 50 is arranged on the bracket shaft 231, so that the swingable rocking arm 50 can swing back and forth on the bracket shaft 231.
[0034] like Figure 1 and Figure 2As shown, in a preferred embodiment, the swingable rocking arm 50 is provided with a mounting hole 520, and the bracket shaft 231 is disposed in the mounting hole 520. For example, the mounting hole 520 is disposed on a side of the swingable rocking arm 50 away from the driving mechanism 10, the bracket shaft 231 passes through the mounting hole 520, and both ends of the bracket shaft 231 are fixed to the second fixing hole 232 and the third fixing hole 233, so that the swingable rocking arm 50 can swing back and forth on the bracket shaft 231.
[0035] In a preferred embodiment, the swingable rocking arm 50 is provided with a groove 530, and the sliding shaft 510 is located in the groove 530. The swingable rocking arm is provided with two symmetrical support blocks 540, and the groove 530 is formed between the two support blocks 540, and the two ends of the sliding shaft 510 are respectively fixedly arranged on the two support blocks 540. The two symmetrical support blocks 540 are arranged toward the driving mechanism 10, and the sliding shaft 510 is arranged on one side of the two support blocks 540 close to the eccentric chain rod 30. By setting the sliding shaft 510 on the side of the two support blocks 540 close to the eccentric chain rod 30, it is convenient for one end of the movable chain rod 40 to be arranged on the sliding shaft 510, and the other end to be arranged on the eccentric chain rod 30.
