Description

Technical Field

[0001] This invention relates to a children's rocking chair. Background Technology

[0002] For families with infants and toddlers, parents who can care for their children while also having time to work or do housework have a strong need for a low-cost, wide-amplitude rocking chair, especially one with multiple swing modes. While some rocking chairs have a fixed seat and rotating shafts, which can cause dizziness and discomfort for children, others use a Z-shaped design with two rotating shafts. The seat swings relative to the support frame, but this method has limitations: limited range of motion, high manufacturing requirements for the seat, shafts, and support frame, and high cost. A further major problem is that the two shafts only allow for a single swing mode. Therefore, the market demands a low-cost rocking chair with a wide swing mode, especially one that offers two different swing modes simultaneously. Utility Model Content

[0003] The purpose of this invention is to provide a low-cost rocking chair with a large swing amplitude, which can perform multiple rocking modes for children.

[0004] This invention is achieved through the following technical solution: It includes a seat, a support frame, and a seat limiting mechanism. The support frame includes a drive mechanism, which includes a drive motor, a drive motor power output unit, and a rotating shaft. The seat is used to carry a child. The rotating shaft independently supports the seat. One end of the rotating shaft is pivotally mounted on the support frame and fixedly connected to the drive motor power output unit. The other end of the rotating shaft is pivotally connected to the seat. The vertical line between the pivot point of the rotating shaft and the support frame and the ground deviates from the vertical line between the pivot point of the rotating shaft and the seat and the ground. The seat limiting mechanism includes a limiting member and a limiting mating member that cooperates with the limiting member. When the rotating shaft rotates, the limiting member and the limiting mating member move relative to each other. The seat limiting mechanism limits the angle between the seat and the rotating shaft to a set angle.

[0005] Furthermore: the support frame includes a base and a mounting box, the mounting box is connected to the base, the limiting member is connected to the seat body, the connection point of the limiting member and the seat body is perpendicular to the vertical line of the ground, the other end of the limiting member and the pivot point of the seat body is perpendicular to the vertical line of the ground, the limiting fitting member is disposed on the mounting box, and when the limiting member moves relative to the limiting fitting member, the limiting member generates at least one movement trajectory line including low to high and then low or high to low and then high.

[0006] Furthermore: the limiting component is a movable component, and the limiting mating component is a movable groove. When the rotating shaft rotates, the movable component moves relative to the movable groove. The movable component is mounted on the base, and the movable groove that mates with the movable component is mounted on the mounting box.

[0007] Furthermore: A rotating component is provided on the moving component, the rotating component can rotate around the moving component, and the rotating component mates with the surface of the moving groove.

[0008] Furthermore: the moving groove is an arc-shaped groove. When the rotating shaft is set to rotate from low to high and then back to low, the arc-shaped groove is set to rotate from low to high and then back to low.

[0009] Furthermore: the moving groove is an irregular wave-shaped groove with alternating high and low points.

[0010] Furthermore: when the seat moves left or right, the moving groove is an inclined groove, and the inclined groove is inclined towards the rear direction of the seat.

[0011] Furthermore: the moving groove is an arc-shaped groove, a V-shaped groove, or an irregular wave-shaped groove with alternating high and low points, and the moving groove is roughly symmetrically arranged on both sides of the projection line on the mounting box when the rotating shaft is rotated to the highest position.

[0012] Furthermore, the movable groove is located near the pivot point between the rotating shaft and the mounting box.

[0013] Furthermore, the drive mechanism also includes a sensor mounted on the drive motor, which is connected to a reduction gear set. The sensor can control the drive motor to continuously reciprocate forward and reverse rotation, thereby causing the rotating shaft to continuously reciprocate forward and reverse rotation. The rotating shaft is tilted on the mounting box.

[0014] Furthermore: the movable component is provided with two rotating components, and the mounting box is provided with two movable slots that correspond to and cooperate with the two rotating components. Attached Figure Description

[0029] Now refer to the appendix Figures 1-13 Embodiments of the present invention are described.

[0030] The device includes a seat 1, a support frame 2, and a seat limiting mechanism 3. The support frame 2 includes a drive mechanism 4, which includes a drive motor 5, a drive motor power output unit 6, and a rotating shaft 7. The seat 1 is used to carry a child. The rotating shaft 7 independently supports the seat 1. One end of the rotating shaft 7 is pivotally mounted on the support frame 2 and fixed to the drive motor power output unit 6. The other end of the rotating shaft 7 is pivotally connected to the seat 1. The vertical line between the pivot point of the rotating shaft 7 and the support frame 2 and the ground is offset from the vertical line between the pivot point of the rotating shaft 7 and the seat 1 and the ground. The seat limiting mechanism 3 includes a limiting member 9 and a limiting fitting member 10 that cooperates with the limiting member 9. When the rotating shaft 7 rotates, the limiting member 9 and the limiting fitting member 10 move relative to each other. The seat limiting mechanism 3 limits the angle between the seat 1 and the rotating shaft 7 to a set angle. A rotating shaft 7 independently supports the base 1. When the rotating shaft 7 rotates, a limiting member 9 and a limiting mating member 10 move relative to each other, thereby limiting the angle between the base 1 and the rotating shaft 7. This structure is very simple, overcomes the problem of interference between two shafts, and also overcomes the high requirements of manufacturing processes. The swing amplitude can be made very large, solving the problem of small swing amplitude, and two different swing modes can be realized. The core content of this invention is that a rotating shaft 7 pivots and independently supports the base 1, and the limiting member 9 and the limiting mating member 10 move relative to each other to limit the angle between the base 1 and the rotating shaft 7. There are many possible angles between the base 1 and the rotating shaft 7, and all of them fall within the protection scope of this invention.

[0031] The support frame 2 includes a base 14 and a mounting box 8. The mounting box 8 is connected to the base 14, and a limiting member 9 is connected to the seat 1. The connection point of the limiting member 9 and the seat 1 is perpendicular to the ground. The other end of the limiting member 9 and the pivot point of the seat 1 are perpendicular to the ground. The connection between the limiting member 9 and the seat 1 and the perpendicular to the rotation axis 7 generates a lever arm. The limiting member 9, through the limiting fitting member 10, limits the seat 1 to require less effort, thereby making the rotation axis 7 swing more smoothly. The limiting fitting member 10 is disposed on the mounting box 8. When the limiting member 9 moves relative to the limiting fitting member 10, the limiting member 9 generates at least one movement trajectory line including either low to high and then low or high to low and then high. The movement trajectory line generated by the limiting member 9 can be of many kinds, as long as it includes a movement trajectory line from low to high and then low or from high to low and then high, it falls within the protection scope of this invention.

[0032] The limiting component 9 is a movable component, and the limiting mating component 10 is a movable groove. When the rotating shaft 7 rotates, the movable component moves relative to the movable groove. The movable component is limited by the movable groove, resulting in a simple structure that is easy to implement. The movable component is set on the base 1, and the movable groove that mates with the movable component is set on the mounting box 8. This arrangement ensures that the movable component on the base 1 always maintains a fixed distance from the pivot point between the rotating shaft 7 and the base 1, thus preventing the base 1 from rotating around the rotating shaft 7. The movable component is connected to the base 1, and the movable groove is set on the mounting box 8, resulting in a simple structure.

[0033] A rotating component 11 is provided on the moving component. The rotating component 11 can rotate around the moving component. The rotating component 11 is in contact with the surface of the moving groove. By providing the rotating component 11 on the moving groove and the area of ​​the moving groove being in contact, friction is reduced and the rocking chair swings smoothly. There are many types of rotating components 11. In this case, the rotating component 11 provided on the moving component is a bearing.

[0034] The moving groove is an arc-shaped groove. When the rotating shaft 7 is set to rotate from low to high and then back to low, the arc-shaped groove is set to rotate from low to high and then back to low, such as... Figure 1 As shown, when the rotating shaft 7 is at its lowest position, the moving part of the moving groove is also at its lowest position, as... Figure 2 As shown, when the rotating shaft 7 rotates to a high position, the moving part is also at a high position in the moving groove, as... Figure 3 As shown, when the rotating shaft 7 is at its lowest position, the moving part of the moving groove is also at its lowest position, as... Figure 1 , Figure 2 , Figure 3 This refers to the movement of the rotating shaft 7 from its starting point to its ending point, and also from a low position to a high position and then back to a low position. It also refers to the movement of the moving parts from a low position to a high position and then back to a low position. For example... Figure 1 , Figure 2 , Figure 3 When the rotating shaft 7 is rotated, the seat 1 does not change angle relative to the support frame 2, but only moves a distance relative to the support frame 2. Figures 1 to 3 This invention explains that if the seat 1 moves relative to the support frame 2, there will be no angular change in the swing. If the swing amplitude is to be increased, the length of the moving groove can be extended. Because a single rotating shaft 7 independently pivots and supports the seat 1, it overcomes the disadvantages of interference between the rotation of two shafts when the swing amplitude is increased and the disadvantages of high process requirements for two shafts. This invention explains that the core content of the invention is that a shaft independently supports the seat 1, and the limiting member 9 moves relative to the limiting fitting member 10, thereby limiting the angle set between the seat 1 and the rotating shaft 7, achieving the characteristics of simple structure, low cost, large swing amplitude, and good function.

[0035] The moving groove is an irregularly wavy groove with alternating high and low elevations, such as... Figure 7 , Figure 8 , Figure 9 As shown, the moving part alternates between low and high points and then back to high points, during which the seat 1 both swings and rotates relative to the support frame 2 at different angles, thus achieving multi-functional movement. Figures 7 to 11When the rotating shaft 7 is rotated, the seat 1 swings relative to the support frame 2, moving a distance, while the seat 1 also rotates and swings relative to the rotating shaft 7, thus realizing two different swing modes simultaneously. This increases the fun of the children's rocking chair and meets the diverse needs of consumers. The simultaneous realization of two different swing modes is the core content of this invention. One shaft independently supports the seat 1, and the limiting member 9 moves a distance relative to the limiting fitting member 10, thereby limiting the angle set between the seat 1 and the rotating shaft 7. This cannot be achieved with two rotating shafts 7. Therefore, under the premise of possessing the core content of this invention, the simultaneous realization of two different movements is achieved simply by changing the shape of the moving groove so that the movement trajectory lines generated by the moving member are different. The shape of the moving groove can be set in various ways, and the shape of the moving groove does not affect the protection scope of this invention.

[0036] When the seat 1 moves left or right, the moving groove is an inclined groove, which is angled towards the rear of the seat 1. The inclined groove is angled towards the rear of the seat 1 to prevent the seat 1 from tilting backward after a child sits on it; if the seat 1 tilts backward, the limiting member 9 will engage with the rotating member 11 on the limiting member 9. The inclined groove is angled towards the rear of the seat 1 to ensure smooth movement or swinging of the seat 1.

[0037] like Figure 6 The moving groove is an arc-shaped groove or an irregular wave-shaped groove with alternating heights. The moving groove is arranged approximately symmetrically on both sides of the projection line on the mounting box 8 when the rotating shaft 7 is rotated to the highest position, so that the moving groove is rationally arranged on the mounting box 8, thereby reducing the volume of the mounting box 8.

[0038] The movable slot is positioned near the pivot point between the rotating shaft 7 and the mounting box 8. This design reduces the size of the mounting box 8 and improves its appearance.

[0039] The drive mechanism 4 also includes a sensor 12 mounted on the drive motor 5. A reduction gear set 13 is connected to the drive motor 5. The sensor 12 controls the drive motor 5 to continuously reciprocate in both directions, thereby causing the rotating shaft 7 to continuously reciprocate in both directions. By detecting the rotation angle of the rotating shaft 7 and the forward and reverse rotation of the drive motor 5 through the sensor 12, the moving distance of the seat 1 is controlled. The reduction gear set 13 reduces speed and increases force, resulting in a simple structure and low cost. The rotating shaft 7 is inclinedly mounted on the mounting box 8. The aforementioned drive mechanism 4 reduces costs. The inclined mounting of the rotating shaft 7 on the mounting box 8, pivotally connected to the seat 1, allows the seat 1 to convert kinetic and potential energy, achieving the purpose of saving effort.

[0040] like Figure 13The movable part is provided with two rotating parts 11, and the mounting box 8 is provided with two moving slots that correspond to and cooperate with the two rotating parts 11. The purpose of setting two rotating parts 11 is to prevent the movable part from rotating around the rotating shaft 7 with the base body 1 when it moves relative to the moving slot.

[0041] This invention has a simple structure and low cost. The rocking chair seat 1 is stable and can realize two different swing modes at the same time. It was invented by engineers after long-term and careful research. It is not something that people in the field would easily think of, and it is not common knowledge. The "one end" and "the other end" described in this invention are only distinguished by the names of the things. They can be understood as the top of the thing or a section of the thing.
