Description

Infant exercise device and buffer mechanism thereof

Technical Field

With the continuous improvement of living standard of people, the infant sport device is widely entered into families of ordinary people. The infant motion device can be used for sleeping, eating or comfortable seating of an infant, and provides a caregiver with great convenience, and the caregiver tends to place the infant in the infant motion device regardless of home or other occasions near home. However, when the baby cries on the baby moving device, the caregiver needs to take the baby out of the baby moving device, pacify the baby until the baby calms down, and then put the baby into the baby moving device, which causes inconvenience to the caregiver.

Therefore, infant sports apparatuses with a soothing function, such as infant swings, have been developed. The common infant swing comprises a support, a rotating seat, a hanging rod and a seat body, wherein the support and the hanging rod are combined together through the rotating seat, and the seat body is hung on the support through the hanging rod. Specifically, the rotating seat is pivoted with the support, one end of the suspender is fixedly connected with the rotating seat, and the other end of the suspender is fixedly connected with the seat. When the baby cries in the infant swing, a caregiver only needs to start the driving motor to enable the seat body and the suspender to rotate around the rotating seat to swing the seat body, so that the aim of soothing the baby is fulfilled.

However, when the conventional infant exercise device swings to the limit position, the direction change of the infant exercise device is buffered due to lack of buffering force, and the direction change of the infant exercise device is realized by direct direction change of power, so that when the conventional infant exercise device reaches the limit position, the impact force on an infant is large, the infant is uncomfortable, and the unbuffered direction change easily causes damage to a transmission part, so that normal movement of the infant exercise device cannot be ensured.

Detailed Description

Embodiments of the present invention will now be described with reference to the drawings, wherein like reference numerals represent like elements throughout.

As shown in fig. 1-6, the child motion device of the present invention comprises a body 1, a seat assembly 2, a driving assembly 3, a connecting rod assembly 5 and a buffering mechanism 4, wherein the driving assembly 3 and the buffering mechanism 4 are disposed in the body 1, the body 1 covers and protects the two by a decoration cover 1a, the seat assembly 2 is rotatably connected to the body 1, and the driving assembly 3 is connected to the seat assembly 2 by the buffering mechanism 4. 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.

As shown in fig. 5, in order to make the seat assembly 2 rotate more flexibly relative to the body 1, a rotating shaft 7 is rotatably disposed on the body 1, the seat assembly 2 is connected to the rotating shaft 7, and the driving assembly 3 drives the seat assembly 2 to perform reciprocating swing motion around the rotating shaft 7; the seat assembly 2 is positioned by the rotating shaft 7, so that the swinging motion of the seat assembly 2 is more stable and smooth.

As shown in fig. 4-6, the present invention uses the connecting rod assembly 5 to convert the rotation output of the driving assembly 3 into the reciprocating swing of the seat assembly 2, the connecting rod assembly 5 provided by the present invention includes a crank 51 and a rocker 52, one end of the crank 51 is connected with the output end of the driving assembly 3, the other end of the crank 51 is pivoted with one end of the rocker 52, the other end of the rocker 52 is pivoted with the buffer assembly 6, so that the rocker 52 is pivoted between the crank 51 and the buffer assembly 6, the driving assembly 3 drives the crank 51 to make a circular motion (i.e., rotate), the rotation of the crank 51 drives the rocker 52 pivoted therewith to make a reciprocating swing motion (i.e., the rocker makes a reciprocating rotation within a certain angle range, the swing angle of the rocker is the same as the swing angle of the seat assembly 2), and the reciprocating swing motion of the rocker 52 drives the seat assembly 2 to make a reciprocating swing motion synchronously; the invention effectively converts the rotation output of the driving component 3 into the reciprocating swing motion of the seat component 3 by the connecting rod component 5 consisting of the crank 51 and the rocker 52, and has simple structure and practicability; it should be noted that one or more connecting rods may be pivotally connected between the crank 51 and the rocker 52, and those skilled in the art can make the determination of whether or not to pivotally connect the connecting rods between the crank 51 and the rocker 52 and the determination of the number of pivotally connected connecting rods without any creative work according to the requirements of the actual situation, such as the requirements of the site installation station, and the like, and the detailed description is omitted here.

With continuing reference to fig. 4-6, in order to further improve the buffering effect and the structural simplicity of the buffering mechanism 4 of the present invention, the buffering assembly 6 of the buffering mechanism 4 of the present invention includes a fixing portion 61 and a buffering portion 62 that are connected to each other, the connecting rod assembly 5 is pivoted to the buffering portion 62, the fixing portion 61 is fixedly connected to the rotating shaft 7, and the rotating shaft 7 is connected to the seat assembly 2, so that the rotating of the driving assembly 3 makes the fixing portion 61 perform reciprocating oscillating motion under the action of the connecting rod assembly 5, the reciprocating oscillating motion of the fixing portion 61 drives the rotating shaft 7 to perform reciprocating rotation in the left-right direction around the axis thereof (i.e., reciprocating oscillating motion, taking any point on the surface of the rotating shaft 7 as an observation point, it can be observed that the observation point performs reciprocating oscillating motion under the driving of the driving assembly, the reciprocating rotation in the left-right direction of the rotating shaft 7 synchronously drives the seat assembly 2 fixed thereon to perform reciprocating oscillating motion, when the seat assembly 2 oscillates to the right-left-side limit position (i.e., when the rotating shaft 7 rotates clockwise to the limit position), the left-side limit position), the buffering portion 62 presses the buffering portion to provide the buffering portion 2, and the impact force to counteract the seat 2.

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.
