Referring to fig. 1-2, a connection structure 100 in accordance with an embodiment of the first aspect of the present invention is shown. The connecting structure 100 includes two portions, a first portion 110 and a second portion 120. The first portion 110 defines a first mounting hole 111, the first mounting hole 111 is used for mounting a first shaft 112, and the first shaft 112 rotates around a first shaft 112 axis relative to the connecting structure 100 in the first mounting hole 111. The first shaft 112 may be connected to a rocking beam, or the first shaft 112 may be part of a rocking beam, or the first shaft 112 may be the rocking beam itself. Of course, the first shaft 112 may also be connected to an object (e.g., a seat) to be shaken. In the examples below, the first shaft 112 is part of a rocking beam. It is understood that the first shaft 112 axis may coincide with the first shaft 112 axis, the first mounting hole 111 centerline, and may be disposed so as not to coincide. The second portion 120 defines a second mounting hole 121, the second mounting hole 121 is used for mounting a second shaft 122, and the second shaft 122 rotates around a second shaft 122 axis relative to the connecting structure 100 in the second mounting hole 121. The first axis 112 and the second axis 122 are not staggered in parallel. As previously described, the second shaft 122 may be connected to an object to be shaken (e.g., a chair or other object that needs to be shaken). It is understood that the second shaft 122 axis may coincide with the second shaft 122 axis, the center line of the second mounting hole 121, and may be arranged to be misaligned. By arranging the first mounting holes 111 and the second mounting holes 121 to mount the first shafts 112 and the second shafts 122 respectively and enabling the first shafts 112 rotating around the first shafts 112 and the second shafts 122 rotating around the second shafts 122 to be arranged in a staggered mode not to be parallel, when the swinging motion of the first shafts 112 is transmitted to the second shafts 122, the first shafts 112 and the second shafts 122 can rotate respectively, and the flexibility of motion transmission is increased.

Referring to fig. 1, in some embodiments, the first portion 110 and the second portion 120 are fixedly coupled. Although the first portion 110 is fixedly connected to the second portion 120, the connection structure 100 still has great flexibility in power transmission through the first mounting hole 111 and the second mounting hole 121. For example, the second shaft 122 installed in the second installation hole 121 may be swung by the first shaft 112 installed in the first installation hole 111, but at the same time, the first shaft 112 and the second shaft 122 may each rotate in the first installation hole 111 and the second installation hole 121, respectively. It is understood that the first portion 110 and the second portion 120 may also be movably connected by a connecting member. In some embodiments, the first portion 110 and the second portion 120 are integrally formed for ease of manufacturing. It is understood that the first portion 110 and the second portion 120 may be separately disposed. In some embodiments, bearings 130 are disposed within each of the first mounting hole 111 and the second mounting hole 121. The first shaft 112 and the second shaft 122 are supported by bearings 130. Referring to fig. 2, the second shaft 122 is supported at both ends by bearings 130, and although not shown, the connecting structure 100 also has bearings 130 that support the first shaft 112.

In some embodiments, a first stop assembly is also included that limits movement of the first shaft 112 relative to the first portion 110 between an upper limit position and a lower limit position. Sometimes, when a plurality of (for example, two) connecting structures 100 are connected to the swung component, because the swinging amplitudes of the first shafts 112 of the plurality of connecting structures 100 are not consistent, it is necessary to enable the first shafts 112 to move within a certain range relative to the first portion 110, otherwise, a swinging failure may be caused.

Referring to fig. 2-4, in some embodiments, the first mounting hole 111 is a through hole, and the first shaft 112 is disposed through the first mounting hole 111. The first limiting component comprises a first abutting part 140 and a second abutting part 141 protruding out of the first shaft 112, the first abutting part 140 and the second abutting part 141 are respectively located on two sides of the first portion 110, when the first abutting part 140 abuts against the first portion 110, the first shaft 112 is located at an upper limit position relative to the first portion 110, and when the second abutting part 141 abuts against the first portion 110, the first shaft 112 is located at a lower limit position relative to the first portion 110. That is, the first abutting portion 140 and the second abutting portion 141 provided on the first shaft 112 restrict the relative movement between the first portion 110 and the first shaft 112 between the first abutting portion 140 and the second abutting portion 141, so that even if the swing amplitudes between the plurality of first shafts 112 are not uniform when the plurality of first shafts 112 are provided, the swing can be achieved within a certain range. While preventing the first shaft 112 from being disengaged from the first mounting hole 111. Referring to fig. 7, two connecting structures 100, specifically, second shafts 122 connected to the two connecting structures 100, are connected to both ends of the seat assembly 160. The first shaft 112 is a part of a rocking rod, the seat assembly 160 is driven to rock through the rocking motion of the first shaft 112, and the rocking knots of the two first shafts 112 are asynchronous, so that the first limiting assembly limits the first shaft 112 to be separated from the connecting structure 100, and simultaneously, the rocking of the first shaft 112 can be transmitted to the seat assembly 160, and the seat assembly 160 can be rocked, otherwise, the seat assembly 160 cannot rotate due to the inconsistent rocking knots of the first shaft 112 and the second shaft 122. Because the connecting structure 100 has a certain displacement in both the vertical direction and the horizontal direction when moving between the first abutting portion 140 and the second abutting portion 141, the effect caused by the asynchronous movement of the first shaft 112 and the second shaft 122 can be counteracted, so that the seat assembly 160 can still swing when the asynchronous movement of the first shaft 112 and the second shaft 122 is realized.

Referring to fig. 5-6, in some embodiments, the first limiting assembly includes a first groove 150 opened on the first shaft 112, the first groove 150 being located in the first mounting hole 111, and a first protrusion 151 connected to the first portion 110, the first protrusion 151 extending at least partially into the first protrusion 151 of the first groove 150. The relative movement of the first portion 110 and the first shaft 112 can be restricted between both ends of the first groove 150 by the first protrusion 151 and the groove. In some embodiments, the first protrusion 151 is detachably connected to the wall of the first hole, facilitating replacement.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the gist of the present invention.
