[0034] The technical solutions in the application will be described clearly and completely below in combination with the drawings in the application / embodiments of the application. Obviously, the described embodiments are only some of the embodiments of the application, not all. The description of the at least one exemplary embodiment is actually only illustrative, not as any limitation on the application and its application or use. Embodiment one

[0035] The embodiment provides a swing to solve the problem of unstable swing amplitude of the traditional swing in the prior art.

[0036] With reference to Figures 1 to 6 , the swing provided by the embodiment includes a swing arm 2, the swing arm 2 is connected with a seat 10, the swing arm 2 is further rotationally connected with a rotating shaft 3, the two connecting points of the swing arm 2 should be spaced apart by a set distance, and in addition, the swing arm 2 is provided with a movable slot 8.

[0037] The swing further comprises a curved arm 7 and an input shaft 6.4 for driving the curved arm 7 to rotate, i.e. the input shaft 6.4 is in torque connection with the curved arm 7, the curved arm 7 is connected with a movable block 9 which is spaced apart from the rotation center of the curved arm 7 by a set distance. When the swing is assembled and in use, the movable block 9 is located in a movable groove 8, the inner diameter of the movable groove 8 is larger than the outer diameter of the movable block 9 so as to facilitate the interaction of the movable block 9; when the curved arm 7 rotates, the movable block 9 touches the inner wall of the movable groove 8 and exerts force on the inner wall of the movable groove 8, and the swing arm 2 swings under the driving of the movable block 9.

[0038] The torque connection between the input shaft 6.4 and the curved arm 7 can be in the form of direct rotation connection or through intermediate components.

[0039] In use, the participant sits on the seat 10, the external driving input shaft 6.4 rotates, the input shaft 6.4 drives the curved arm 7 to rotate, and since the movable block 9 is spaced apart from the rotation center of the curved arm 7 by a set distance, the movable block 9 rotates around the rotation center of the curved arm 7. Since the movable block 9 is also located in the movable groove 8, when the movable block 9 rotates around the rotation center of the curved arm 7, the movable block 9 also slides against the inner wall of the movable groove 8, and the swing arm 2 is in rotation connection with the rotation shaft 3, so when the movable block 9 slides in the movable groove 8, it also produces a pushing action on the swing arm 2, so that Figure 5 , the swing arm 2 periodically swings around the rotation shaft 3 under the pushing action. Since the structure system composed of the input shaft 6.4, the curved arm 7, the movable block 9, the movable groove 8, the rotation shaft 3 and the swing arm 2 is relatively fixed and designed, the structure system composed of the input shaft 6.4, the curved arm 7, the movable block 9, the movable groove 8, the rotation shaft 3 and the swing arm 2 converts the rotation of the input shaft 6.4 into regular swinging of the swing arm 2, so that Figure 5 and Figure 6 , the periodic swinging of the swing arm 2 is reflected on the seat 10, i.e. the seat 10 swings periodically, and the swinging amplitude and the maximum angle are relatively stable and are restricted by the structure system composed of the input shaft 6.4, the curved arm 7, the movable block 9, the movable groove 8, the rotation shaft 3 and the swing arm 2, and the swinging frequency is positively correlated with the input rotation speed of the input shaft 6.4.

[0040] As one of the embodiments, referring to Figure 1 , the input shaft 6.4 can be installed on the support frame 4, the support frame 4 serves as the support base of the input shaft 6.4, and the input shaft 6.4 protrudes outward from the support frame 4 so as to facilitate the external input of power to the input shaft 6.4, such as installing a hand crank on the input shaft 6.4. Embodiment two

[0041] The embodiment provides a swing, and the embodiment is optimized on the basis of the embodiment one to improve technical effects and refine a technical scheme. Details not described in the embodiment are shown in the embodiment one.

[0042] The embodiment one mentions that the input rotating speed of the input shaft 6.4 is one of the keys affecting the swing frequency of the swing arm 2. On the basis of controlling the swing amplitude and the maximum angle in the embodiment one, in order to realize automatic control and save manpower, and to promote the stability of the swing frequency, the embodiment refers to Figure 1 , and the swing further comprises a motor 6.1, the motor 6.1 is in transmission connection with the input shaft 6.4, the motor 6.1 drives the input shaft 6.4 to rotate, and the swing amplitude and the maximum angle of the swing arm 2 and the stability of the swing frequency are realized.

[0043] Generally, the rotating speed of the motor 6.1 that can be purchased is fast and the torque is low, and the mass inertia of the participant sitting on the seat 10 is high, so the swing arm 2 needs a large torque to observably drive the seat 10 to swing. As one of the embodiments, the embodiment refers to Figure 1 and Figure 4 , and the swing provided by the embodiment further comprises a variable gear set 6.3, the variable gear set 6.3 is in transmission connection with the motor 6.1 through a transmission belt 6.2, the variable gear set 6.3 is also in transmission connection with the input shaft 6.4, the motor 6.1 outputs at a high rotating speed and a low torque to the variable gear set 6.3, the torque is improved through conversion inside the variable gear set 6.3, and then the variable gear set 6.3 outputs to the input shaft 6.4, so that the swing arm 2 observably drives the seat 10 to swing.

[0044] The embodiment refers to Figure 1 and Figure 6 , and the swing provided by the embodiment further comprises a support frame 4, the support frame 4 is a support base of the swing, and the embodiment refers to Figure 1 , the support frame 4 is provided with a third bearing 6.6, the third bearing 6.6 is in rotary connection with the support frame 4, both ends of the input shaft 6.4 are sleeved into two third bearings 6.6, that is, the input shaft 6.4 is also in rotary connection with the third bearing 6.6, so as to obtain the support of the support frame 4, when the movable block 9 drives the swing arm 2 to swing in the movable groove 8, the reaction force generated by the swing arm 2 on the movable block 9 can be transmitted to the input shaft 6.4 through the curved arm 7, and the input shaft 6.4 transmits the reaction force to the support frame 4 through the third bearing 6.6.

[0045] In order to protect the stable operation of the variable gear set 6.3, the embodiment refers to Figure 1 , as one of the embodiments, the swing further comprises a second housing 6.5 connected with the support frame 4, the variable gear set 6.3 is installed in the second housing 6.5, and the embodiment refers to Figure 2 and Figure 5The first shell 5 can be further installed on the support frame 4, and the second shell 6.5, the motor 6.1 and the transmission belt 6.2 can be installed in the first shell 5 for protection.

[0046] As one of the embodiments, when the torque transmitted between the input shaft 6.4 and the curved arm 7 is large, in order to ensure the stability of the force transmission process and avoid the phenomenon of jamming, the input shaft 6.4 is directly connected with the rotation center of the curved arm 7, and a nut is sleeved on the position of the input shaft 6.4 penetrating out of the rotation center of the curved arm 7 to prevent the input shaft 6.4 from being pulled out. Figure 3 As one of the embodiments, the input shaft 6.4 is directly connected with the rotation center of the curved arm 7, and a nut is sleeved on the position of the input shaft 6.4 penetrating out of the rotation center of the curved arm 7 to prevent the input shaft 6.4 from being pulled out. Figure 3 As one of the embodiments, the curved arm 7 can be a classic single-arm structure, and the curved arm 7 can also be a disc structure as shown in the figure, which is more stable.

[0047] The movable block 9 slides in the movable groove 8 and synchronously drives the swing arm 2 to swing. When the swing arm 2 swings, there is a large friction force between the movable block 9 and the inner wall of the movable groove 8. A smooth material such as graphite can be brushed on the surface of the movable block 9 to overcome the influence of the friction force on the sliding effect of the movable block 9, but the smooth material is easy to wear. In order to reduce the friction force between the movable block 9 and the inner wall of the movable groove 8 for a long time, the first bearing 9.1 is selected as the movable block 9. Figure 3 Figure 4 The first bearing 9.1 rolls in the inner wall of the movable groove 8 while driving the swing arm 2 to swing, and the rolling friction force of the first bearing 9.1 is small, which can ensure long-term use. As one of the embodiments, a bolt can be sleeved in the first bearing 9.1, and the first bearing 9.1 is fixed on the curved arm 7 through the bolt. The first bearing 9.1 remains in rotation connection with the curved arm 7 and remains fixed on the curved arm 7.

[0048] As one of the embodiments, the swing arm 2 includes an arm body 2.1 in rotation connection with the rotating shaft 3, and the movable groove 8 is arranged on the arm body 2.1. The swing arm 2 further includes a second bearing 2.2 in rotation connection with the arm body 2.1. Figure 1 Figure 5 Figure 6 The swing arm 2 includes an arm body 2.1 in rotation connection with the rotating shaft 3, and the movable groove 8 is arranged on the arm body 2.1. The swing arm 2 further includes a second bearing 2.2 in rotation connection with the arm body 2.1. The hanging rope 1 is sleeved on the second bearing 2.2, and the hanging rope 1 is connected with the seat 10. When the arm body 2.1 swings under the drive of the movable block 9, the second bearing 2.2 rotates around the rotating shaft 3 through the arm body 2.1, and the hanging rope 1 is simultaneously affected by the gravity of the seat 10. Under the drag of the second bearing 2.2 and the gravity of the seat 10, the hanging rope 1 swings, and the hanging rope 1 can rotate around the second bearing 2.2, which delays the friction between the hanging rope 1 and the second bearing 2.2 and improves the service life of the hanging rope 1. Figure 2 ​​​The swing arm 2 includes two arm bodies 2.1. The two ends of the second bearing 2.2 are respectively two arm bodies 2.1. The arm body 2.1 near the curved arm 7 also has a movable groove 8.

[0049] Furthermore, the suspension rope 1 is hinged to the swing arm 2 with the second bearing 2.2 as the rotation center. Since the seat 10 is relatively heavy, in actual use, the swing periods of the seat 10 and suspension rope 1 do not completely coincide with the swing period of the swing arm 2. This is to ensure that when the suspension rope 1 is at its maximum angle and the seat 10 swings to its highest position, the swing arm 2 swings in the opposite direction towards the seat 10, accelerating the descent of the seat 10 and suspension rope 1 and accumulating kinetic energy. Additionally, when the suspension rope 1 is almost vertical and the seat 10 swings to its lowest position, the swing arm 2 swings in the same direction towards the seat 10, assisting the seat 10 and suspension rope 1 in rising and accumulating gravitational potential energy. Although the swing amplitude of the swing arm 2 appears small, it accumulates kinetic and gravitational potential energy for the seat 10 by pulling it during each swing cycle, thus enabling the seat 10 and suspension rope 1 to swing with a larger amplitude.

[0050] As one embodiment, reference Figure 6 The rotating shaft 3 is supported on the ground by two support frames 4. The support frames 4 are not only the mounting base of the rotating shaft 3, but also prevent the rotating shaft 3 from tilting the support frames 4 inward.

[0051] As one embodiment, the motor 6.1 can also reduce the speed of the input shaft 6.4 through other means, such as a worm gear, which will not be described in detail here.

[0052] refer to Figure 5 , Figure 5 In this embodiment, "A", "B", "C", and "D" represent the swing angles of the swing arm 2 when the movable block 9 on the curved arm 7 rotates to four different positions. Only in this embodiment... Figure 5 Taking the presented perspective as an example, in case "A", when the movable block 9 is located above the curved arm 7, the swing angle of the swing arm 2 is 0; in case "B", when the movable block 9 rotates to the left side of the curved arm 7, the swing arm 2 swings to the left; in case "C", when the movable block 9 rotates to the lower part of the curved arm 7, the swing arm 2 returns from swinging to the left to the position with a swing angle of 0; in case "D", when the movable block 9 rotates to the right side of the curved arm 7, the swing arm 2 swings to the right; in case "A", when the movable block 9 rotates to the upper part of the curved arm 7, the swing arm 2 returns from swinging to the right to the position with a swing angle of 0; and so on, the seat 10 presents...
