The seat assembly 2 has a supporting member 21 and a supporting base 22, wherein the two supporting members 21 are connected with each other by a connecting joint 23 of the supporting base 22 to form a ring structure, so as to form a sitting space for a child to sit on. The driving component 3 drives the seat component 3 to do reciprocating swing motion under the action of the buffer mechanism 4, namely the seat component 2 rotates back and forth in a certain angle range relative to the body 1, when the seat component 2 swings to the right side and the left side limit positions (namely, the right side limit position is the limit position to which the seat component rotates clockwise, and the left side limit position is the limit position to which the seat component rotates anticlockwise). The buffer mechanism 4 is extruded by the seat component 2 to deform so as to provide buffer force; specifically, the damping mechanism 4 of the present invention includes a damping assembly 6, a link assembly 5 pivotally connected between the driving assembly 3 and the damping assembly 4, the damping assembly 6 connected to the seat assembly 3, and the rotation of the driving assembly 3 drives the seat assembly 2 to perform a reciprocating swing motion relative to the body 1 by the link assembly 5 connected to the damping assembly 6. When seat subassembly 2 swung to extreme position, buffer unit 6 took place to deform and provide the cushion effect by seat subassembly 2's extrusion, because seat subassembly 2 extrudes buffer unit 6 when turning to right side and left extreme position, buffer unit 6 took place to deform by seat subassembly 2's extrusion, buffer unit 6's deformation has offset seat subassembly 2 and has reached extreme position and turn to the impact force of swinging back. Therefore, the impact force generated by the deformation of the buffer component 6 of the buffer mechanism 4 effectively counteracts the impact force generated by the seat component 2 when reaching the limit position and swinging back and forth, greatly improves the comfort of the child sitting on the seat component 2, effectively avoids the damage of each transmission component caused by resisting the impact force, and ensures that the child motion device can normally provide the swinging motion for the child.
It should be noted that the driving component 3 for driving the seat component 2 to swing according to the present invention can be any conventional driving mechanism, such as a gear set structure driven by a motor, a belt structure driven by a motor, etc.; for convenience of installation and maintenance, the driving assembly 3 of the present invention is preferably a gear train structure driven by a motor.

With reference to fig. 4-6, preferably, the buffering portion 62 of the present invention is of an elastic structure, the buffering portion 62 of the elastic structure is pressed by the seat assembly 2 to generate elastic deformation, the buffering portion 62 which generates elastic deformation effectively provides buffering for the impact force generated when the seat assembly 2 reaches the limit position and swings back and forth in the direction of rotation, so that the seat assembly 2 moves stably and steadily when swinging back and forth in the direction of rotation, and when the seat assembly 2 is separated from the limit position, the buffering portion 62 which generates elastic deformation automatically resets to wait for the next time when the seat assembly 2 is pressed to generate deformation to provide buffering force; therefore, the impact force generated when the seat assembly 2 reaches the limit position and swings back and forth while steering is offset by the elasticity of the buffer portion 62 having an elastic structure, and the structure is simple and practical.
With continued reference to fig. 4-6, in order to further improve the buffering effect of the buffering portion 62, the buffering portion 62 of the present invention includes a first buffering member 620A and a second buffering member 620B symmetrically disposed left and right, and the first buffering member 620A and the second buffering member 620B are connected to each other and further connected to the rocker 52; when the seat assembly 2 swings to the right limit position, the first cushion 620A is deformed by the extrusion of the seat assembly 2 to provide a cushion force; when the seat assembly 2 swings to the left limit position, the second buffer 620B is deformed by the extrusion of the seat assembly 2 to provide a buffer force; the first cushion 620A and the second cushion 620B are connected by a connecting element 621, the connecting element 621 is located at a middle position between the first cushion 620A and the second cushion 620B, the connecting element 621 is pivotally connected to the rocker 52 of the link assembly 5, and fig. 6 shows a pivotal position P of the connecting element 621 and the rocker 52.
Referring to fig. 5 and 6, preferably, the first and second cushion members 620A and 620B of the present invention are elastic elliptical structures, and the elastic first and second cushion members 620A and 620B should be understood that the material of the first and second cushion members 620A and 620B is elastic, and the elastic first and second cushion members 620A and 620B are elastically deformed when being squeezed by the seat assembly 2 and the rocker 52, so that the first and second cushion members 620A and 620B provide a cushion force for the seat assembly 2 when the seat assembly 2 swings to the extreme position; meanwhile, when the first cushion 620A and the second cushion 620B of the hollow structure are squeezed by the seat assembly 2 and the rocker 52, the hollow structure thereof also provides a cushion force for the seat assembly 2 by deformation; therefore, the first and second cushion members 620A and 620B having elastic elliptical structures provide double cushion force to the seat assembly 2 when the seat assembly 2 swings to the extreme position, thereby greatly improving the cushion effect of the present invention and further improving the comfort of the infant during swinging. Preferably, the elliptical structures of the first and second buffering elements 620A and 620B have a major axis L and a minor axis S, respectively, and are connected to the connecting element 621 and the supporting frame 622 on two ends of the minor axis S, respectively, so as to provide good elastic buffering.

Under the supporting action of the supporting frame 622, the first cushion 620A and the second cushion 620B can keep a more stable posture when being squeezed by the supporting frame 622 and the rocker 52 linked with the seat assembly 2, so as to ensure that the buffering force provided by the first cushion 620A and the second cushion 620B can be stably acted on the seat assembly 2, thereby further improving the buffering effect of the invention.
With reference to fig. 5 and 6, preferably, the supporting frame 622 is an elastic structure, and the supporting frame 622 with the elastic structure connects the first cushion 620A and the second cushion 620B, so that when the first cushion 620A and the second cushion 620B are pressed by the seat assembly 2, a part of the pressing force is transmitted to the supporting frame 622 through the first cushion 620A and the second cushion 620B. The supporting frame 622 is elastically deformed by a force applied thereto, so as to elastically support the first and second buffering members 620A and 620B under compression, thereby reducing an impact force applied to the first and second buffering members 620A and 620B and protecting the first and second buffering members 620A and 620B. Meanwhile, the elastic support of the supporting frame 622 to the first cushion 620A and the second cushion 620B further provides a buffering force for the seat assembly 2, so that the seat assembly 2 obtains a double buffering effect of the first cushion 620A, the second cushion 620B and the supporting frame 622; more specifically, a gap 623 is formed between the supporting frame 622 and the first and second cushions 620A and 620B, and the first and second cushions 620A and 620B and the supporting frame 622 form an annular structure through the gap 623, so that the amount of deformation caused by elastic deformation is further increased, and the buffering effect is further improved.
As shown in fig. 6, the supporting frame 622 of the present invention preferably has a substantially rectangular structure; the supporting frame 622 having a rectangular structure can effectively reduce the area, and can facilitate the first and second buffering members 620A and 620B to be disposed thereon in a left-right symmetrical manner with respect to the long axis direction of the supporting frame 622; simple structure and practicality. In addition, the first and second cushions 620A and 620B are not limited to the above-mentioned embodiments, and the first and second cushions 620A and 620B may be a cushion 620 '(i.e., the first and/or second cushions have a diamond-shaped elastic structure) having a diamond-shaped elastic structure as shown in fig. 6a, or a cushion 620' (i.e., the first and/or second cushions have a lightning-shaped elastic structure) having a lightning-shaped elastic structure as shown in fig. 6B.

As shown in fig. 4 and 5, in order to further improve the smoothness of the linear reciprocating sliding of the seat assembly 2, the sliding member 12 and the supporting member 11 are slidably disposed through the roller 13 and the guide rail 14; specifically, the roller 13 is pivoted on the sliding part 12, the guide rail 14 is fixedly arranged on the bearing part 11, and the sliding part 12, under the action of the linear driving assembly 9, enables the roller 13 pivoted with the sliding part to slide along the guide rail 14, so that the sliding part 12 slides easily and smoothly relative to the bearing part 11; in order to further improve the smoothness and accuracy of the sliding member 12 relative to the bearing member 11, the roller 13 is provided with a sliding slot 15 into which the guide rail 14 extends, and the roller 13 is prevented from separating from the guide rail 14 by the cooperation of the sliding slot 15 and the guide rail 14, so that the roller 13 is ensured to slide along the guide rail 14 all the time, and the accuracy and the smoothness of the sliding of the two are improved.
Referring to fig. 1-6 b, since the child motion device of the present invention has the buffering mechanism 4 for providing buffering force to the seat assembly 2, the buffering mechanism 4 provides buffering force via the buffering assembly 6, the connecting rod assembly 5 is pivotally connected between the driving assembly 3 and the buffering assembly 6, the buffering assembly 6 is connected to the seat assembly 2, and the rotation of the driving assembly 3 is connected to the connecting rod assembly 5 and the buffering assembly 6 to move the seat assembly 2 in a reciprocating swing motion relative to the body 1. When seat subassembly 2 swung to extreme position, buffer unit 6 took place to deform and provide the cushion effect by seat subassembly 2's extrusion, because seat subassembly 2 extrudes buffer unit 6 when turning to right side and left extreme position, buffer unit 6 took place to deform by seat subassembly 2 and link assembly 5's extrusion, buffer unit 6's deformation has offset seat subassembly 2 and has reached extreme position and turn to the impact force of swinging back. Therefore, the impact force generated by the deformation of the buffer component 6 of the buffer mechanism 4 is effectively counteracted to effectively offset the impact force generated by the seat component 2 when reaching the limit position and swinging back and forth in a steering way, so that the comfort of the infant sitting on the seat component 2 is greatly improved, the phenomenon that each transmission part is damaged due to the resistance to the impact force is effectively avoided, and the infant moving device is ensured to normally provide swinging motion for the infant; in addition, in order to provide more exercise modes, the child motion device of the present invention can also slide the seat assembly 2 back and forth, so that the seat assembly 2 can perform a single reciprocating swing, a single reciprocating slide, and both a reciprocating swing and a reciprocating slide simultaneously
