Fig. 1 is a perspective view of a rotary mechanism 100, fig. 2 is a plan view of the rotary mechanism 100, fig. 3 is a sectional view of the rotary mechanism 100 at a-a, in fig. 1 and 2, a part of a second arm 130 is cut away for easy viewing, and referring to fig. 1 to 3, in some specific embodiments of the present invention, the rotary mechanism 100 includes a first arm 110, a first base 120, and a second arm 130, the first arm 110 is provided with a rotary part 111, the first arm 110 is rotatably driven around the rotary part 111, the first base 120 is provided with a first guide part 121 and a second guide part 122 connected, wherein the first guide part 121 circumferentially extends centering on a rotation center Z1 of the rotary part 111, one end of the second guide part 122 is connected to one end 124 (also referred to as a "connection end 124" for easy description) of the first guide part 121, the other end 125 (for easy description, also referred to as "initial end 125") extends in a direction close to the rotation center Z1 of the rotating portion 111, the second arm portion 130 and the first arm portion 110 are slidably connected, and the second arm portion 130 slides along the second guide portion 122 or the first guide portion 121 when the first arm portion 110 rotates about the rotating portion 111.
In the present embodiment, since the second arm 130 slides along the second guide portion 122 or the first guide portion 121 of the first base 120, and the first guide portion 121 circumferentially extends around the rotation center Z1 of the first arm 110, and the second guide portion 122 extends relative to the first guide portion 121 in a direction close to the rotation center Z1 of the first arm 110, when the second arm 130 is driven, the trajectory thereof at least includes a portion far from or close to the rotation center Z1 and a portion rotating around the rotation center Z1, and the rotating mechanism 100 having such a driving trajectory not only has a simple structure, but also conveniently realizes opening or closing of the rotating door 200 having such a rotating mechanism 100 in the circumferential direction, and therefore, the actually occupied area when the door is opened is small.
Although the initial end 125 of the second guide portion 122 may extend in a direction approaching the rotation center Z1 of the rotating portion 111 with respect to the first guide portion 121, in some cases, for example, in order to change an angle at which a below-described swing door 200 (see fig. 7) is opened in the radial direction of the rotating portion 111, an extending locus of the second guide portion 122 may be slightly inclined to a side opposite to the locus of the first guide portion 121 with respect to a line (a chain line in fig. 2) connecting the connecting end 124 of the first guide portion 121 and the rotation center Z1 of the rotating portion 111.
It can be understood that, since the first guide portion 121 extends around the rotation center Z1 of the first arm portion 110, and the second guide portion 122 extends relative to the first guide portion 121 in a direction close to the rotation center Z1 of the first arm portion 110, the second arm portion 130 is gradually separated from the rotation center Z1 of the first arm portion 110 when the second arm portion 130 slides along the second guide portion 122 from the initial end 125, which is the end of the second guide portion 122 closest to the rotation center Z1 of the first arm portion 110; when the second arm portion 130 transits to the first guide portion 121 via the connection end 124, which is a connection point between the second guide portion 122 and the first guide portion 121, and slides along the first guide portion 121, the second arm portion 130 is in a state of rotating circumferentially around the rotation center Z1 of the rotating portion 111.
In this process, since the distance between the position of the second guide portion 122 and the rotation center Z1 of the rotating portion 111 is constantly changed when the second arm portion 130 slides along the second guide portion 122, the first arm portion 110 and the second arm portion 130 are provided in slidable connection in order to enable the second arm portion 130 to smoothly slide in the second guide portion 122 and transition into the first guide portion 121.
In the present embodiment, one end of the first arm 110 is provided with the first sliding slot 112, and the second arm 130 is provided with the first shaft 131, and the first shaft 131 is inserted into the first sliding slot 112 and slides within the first sliding slot 112. Thus, when the first arm 110 rotates, the first chute 112 can push the first shaft 131 and thus the second arm 130 smoothly slides along the second guide 122.
In order to allow the second arm 130 to smoothly transit between the first guide portion 121 and the second guide portion 122, the displacement H of the first shaft 131 slidable in the first slide groove 112 is set to be greater than or equal to the difference between the circular arc radius D of the first guide portion 121 and the distance D from the initial end 125 of the second guide portion 122 to the rotation center Z1 of the rotating portion 111, i.e., H ≧ D. The first chute 112 may penetrate the first arm portion 110 in the thickness direction of the first arm portion 110. The first shaft member 131 may be directly fixed to the second arm portion 130, for example, by various connection methods such as riveting, welding, screwing, and the like, and the first shaft member 131 may be integrally formed to protrude directly from the second arm portion 130. It is conceivable that the first chute 112 may be provided on the second arm portion 130 and the first shaft member 131 may be fixedly provided on the first arm portion 110.
In the present embodiment, the second arm portion 130 is provided with the first sliding portion 133 coaxial with the first shaft member 131, and the first sliding portion 133 slides along the second guide portion 122 or the first guide portion 121. It is conceivable that the first sliding portion 133 may be provided at other positions of the second arm portion 130 as long as the second arm portion 130 can slide along the second guide portion 122 or the first guide portion 121 by the first sliding portion 133. Specifically, the first guide portion 121 and the second guide portion 122 are respectively groove-shaped, and the first sliding portion 133 is accommodated in the second guide portion 122 or the first guide portion 121.
Note that, the first sliding portion 133 is accommodated in the second guide portion 122 or the first guide portion 121, and does not mean that the first sliding portion 133 is accommodated in only one of the second guide portion 122 and the first guide portion 121, but means that the first sliding portion 133 is not accommodated in both the second guide portion 122 and the first guide portion 121, for example, when the first sliding portion 133 slides along the second guide portion 122, it is not in the first guide portion 121, and when the first sliding portion 133 transits from the second guide portion 122 to the first guide portion 121, it is not in the second guide portion 122. The first and second guide parts 121 and 122 may penetrate the first base 120 in the thickness direction of the first base 120. The guide surface 121a of the first guide portion 121 and the guide surface 122a of the second guide portion 122 may protrude in an arc toward the center of the groove, and correspondingly, the first sliding portion 133 may be provided with a first pulley 135 having an arc-shaped inner peripheral surface, and when the first pulley 135 slides along the first guide portion 121 or the second guide portion 122, the arc-shaped inner peripheral surface of the first pulley 135 slides along the guide surface 121a of the first guide portion 121 or the guide surface 121a of the second guide portion 122. Accordingly, the first guide portion 121 and the second guide portion 122 can guide the movement of the second arm portion 130 about the rotation center Z1 of the rotating portion 111, and can restrict the swing of the second arm portion 130 in the axial direction of the rotation center Z1 of the rotating portion 111, thereby further improving the stability of the rotating mechanism 100.
It is conceivable that the first guide portion 121 and the second guide portion 122 each have a projecting wall shape (not shown), and correspondingly, the first sliding portion 133 may be provided with two pinching pulleys (not shown) that pinch the guide wall from both sides of the first guide portion 121 or both sides of the second guide portion 122, respectively, and the first sliding portion 133 may slide while pinching both sides of the first guide portion 121 or both sides of the second guide portion 122 by the two pinching pulleys.
In the embodiment, the second arm portion 130 is provided with an accommodating groove 132, and one end of the first arm portion 110 provided with the first sliding slot 112 is inserted into the accommodating groove 132. Specifically, the height of the accommodating groove 132 is slightly greater than the thickness of the end of the first arm portion 110 at which the first sliding groove 112 is disposed, for example, the height of the accommodating groove 132 may be set to be 0.1mm to 0.2mm greater than the thickness of the end of the first arm portion 110 at which the first sliding groove 112 is disposed, so that the first arm portion 110 can be freely slidably inserted into the accommodating groove 132 while the first arm portion 110 and the second arm portion 130 are restricted from swinging relative to each other, thereby enabling the stability of the rotating mechanism 100 to be further improved. It is conceivable that, in the present embodiment, both ends in the axial direction of the first shaft member 131 may be bridged to the wall portions 136, 137 on both sides of the accommodating groove 132, respectively.
Fig. 4 is a perspective view of the rotary mechanism 100, fig. 5 is a plan view of the rotary mechanism 100, fig. 6 is a sectional view of the rotary mechanism 100 at B-B, and referring to fig. 4 to 6, in some specific embodiments of the present invention, the rotary mechanism 100 further includes a second base 140, the second base 140 is provided with a third guide portion 141 and a fourth guide portion 142 connected to each other, the third guide portion 141 extends circumferentially around a rotation center Z1 of the rotary portion 111, one end 144 of the fourth guide portion 142 is connected to one end 143 of the third guide portion 141, and the other end 145 of the fourth guide portion 142 extends in a direction close to the rotation center Z1 of the rotary portion 111. In response to this, the second arm 130 is provided with a second sliding portion 134, and when the first arm 110 rotates around the rotating portion 111, the second sliding portion 134 slides along the fourth guide portion 142 or the third guide portion 141. Accordingly, by providing at least two guide portions (the first guide portion 121 and the third guide portion 141, or the second guide portion 122 and the fourth guide portion 142), the movement of the second arm portion 130 around the rotation center Z1 of the rotating portion 111 is guided, and the stability of the rotating mechanism 100 can be further improved.
It is conceivable that the third guide portion 141 and the fourth guide portion 142 may be provided in a groove shape, similar to the first guide portion 121 and the second guide portion 122, and the third guide portion 141 and the fourth guide portion 142 may penetrate the second base 140 in the thickness direction of the second base 140. In addition, it is understood that the second sliding portion 134 may be disposed at any position of the second arm portion 130 except for the disposed position of the first sliding portion 133 as long as the second arm portion 130 can smoothly move along the third guide portion 141 or the fourth guide portion 142 while moving around the rotation center Z1 of the rotation portion 111.
In the present embodiment, the first sliding portion 133 is disposed at a lower portion of the second arm portion 130, and the first base 120 is disposed below the second arm portion 130. The second slider 134 is disposed on the upper portion of the second arm 130, and the second base 140 is disposed above the second arm 130. That is, the second arm 130 is sandwiched between the first base 120 and the second base 140. By disposing the second arm portion 130 between the first base 120 and the second base 140 and disposing the first sliding portion 133 and the second sliding portion 134 at the lower portion and the upper portion of the second arm portion 130, respectively, the rotational stability of the second arm portion 130 can be further improved and the rotation mechanism 100 can be made more compact.
In the present embodiment, the third guide portion 141 is provided so as to be swingable about the axial center Z2 of the first slide portion 133 when the second arm portion 130 is slid along the third guide portion 141. The fourth guide portion 142 may be configured to be swingable about the axial center Z2 of the first slide portion 133 when the second arm portion 130 slides along the fourth guide portion 142, and for example, the length h2 of the fourth guide portion 142 may be configured to be slightly longer than the length h1 of the second guide portion 122 (see fig. 2), so that when the first slide portion 133 transitions from the second guide portion 122 to the first guide portion 121, the second slide portion 134 still slides within the fourth guide portion 142, and at this time, the second arm portion 130 swings about the axial center Z2 of the first slide portion 133, so that the second slide portion 134 can smoothly transition from the fourth guide portion 142 to the third guide portion 141. By swinging the second arm 130 about the axial center Z2 of the first sliding portion 133 by the third guide portion 141 and/or the fourth guide portion 142, the swinging angle of the second arm 130 can be changed while the entire second arm 130 is rotated in the circumferential direction about the rotation center Z1 of the rotating portion 111, thereby preventing the second arm 130 from interfering with other components than the rotating mechanism 100.
In the present embodiment, since the second arm 130 is sandwiched between the first base 120 and the second base 140, it is conceivable that the first arm 110 is also disposed between the first base 120 and the second base 140. In addition, in order to improve the stability of the rotation of the first arm portion 110, it is conceivable that a rotation positioning portion 123 is provided in the first base 120, the rotation positioning portion 123 may be, for example, a positioning column protruding in the thickness direction of the first base 120, and in response to this, the rotation portion 111 may have a rotation hole in the first arm portion 110, and the first arm portion 110 may be inserted into the rotation positioning portion 123 of the first base 120 through the rotation portion 111. It is conceivable that the first arm portion 110 may be driven to rotate by the first driving portion 150, the first driving portion 150 is attached to the second base 140, and the first driving portion 150 is connected to the rotation portion 111 of the first arm portion 110, for example, the first driving portion 150 may be selected from a motor, an output shaft 151 of which is inserted into a rotation hole of the rotation portion 111, and is coaxial with the rotation positioning portion 123 of the first base 120.
