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 significant need for a rocking chair that allows their child to sway. While some rocking chairs on the market have a fixed seat and rotating shaft, causing the seat to sway with the shaft, this can easily make children dizzy and uncomfortable. Another type uses two rotating shafts in a Z-shape, with the seat movably connected to them. Although this reduces the angle of rotation, the seat still rotates with the shaft, making it difficult to increase the range of motion and requiring more effort. Current products on the market struggle to meet consumer needs. What is needed is a rocking chair where the seat doesn't rotate with the shaft, offers multiple ranges of motion, and is cost-effective. Summary of the Invention

[0027] Now refer to the appendix Figures 1-4 Embodiments of the present invention are described.

[0028] This invention provides a children's rocking chair, comprising a seat 1, a support frame 2, and a seat limiting mechanism 3. The support frame 2 includes a base 14 and a drive mechanism 4. The drive mechanism 4 includes a drive motor 5, a drive motor power output part 6, a rotating shaft 7, and a mounting box 8. The drive motor power output part 6 is installed inside the mounting box 8. One end of the rotating shaft 7 extends into the mounting box 8 and is fixedly connected to the drive motor power output part 6. The rotating shaft 7 supports the seat 1. One end of the rotating shaft 7 is fixedly connected to the drive motor power output part 6, and the other end of the rotating shaft 7 pivots to the seat 1. When the rotating shaft 7 rotates, the pivot point of the other end of the rotating shaft 7 relative to the fixed point of the one end of the rotating shaft 7 and the drive motor power output part 6 moves. The drive motor 5 and the drive motor power output part 6 are mounted on the mounting box 8, which is fixedly connected to the base 14. The seat limiting mechanism 3 ensures that the angle between the seat 1 and the rotating shaft 7 is maintained at a set angle when the drive motor 5 drives the rotating shaft 7. The seat 1 is used to carry a child. When the rotating shaft 7 rotates, the seat 1 moves a distance along with the rotating shaft 7. Therefore, the seat limiting mechanism 3 includes a moving part 9 and a moving groove 10. The moving part 9 moves in the moving groove 10 to match the distance movement of the seat 1 along with the rotating shaft 7.

[0029] By pivoting the base 1 and the rotating shaft 7, the base 1 does not rotate with the rotating shaft 7, but moves with the rotating shaft 7. This overcomes the problem of the base 1 rotating with the rotating shaft 7. The base limiting mechanism 3 can limit the angle between the base 1 and the rotating shaft 7 to the set angle when the drive motor 5 drives the rotating shaft 7, thus ensuring both the stability of the base 1 and the required angle.

[0030] When the rotating shaft 7 rotates, the seat 1 moves a distance along with the rotating shaft 7. Therefore, the seat limiting mechanism 3 includes a moving part 9 and a moving groove 10. The moving part 9 moves in the moving groove 10 to match the distance movement of the seat 1 along with the rotating shaft 7.

[0031] The movable component 9 is mounted on the support frame 2 or the base 1, and the movable groove 10 that mates with the movable component 9 is mounted on the base 1 or the support frame 2. When the movable component 9 is mounted on the support frame 2, the movable groove 10 that mates with it is mounted on the base 1. Alternatively, the movable component 9 can be mounted on the base 1, and the movable groove 10 that mates with it can be mounted on the support frame 2.

[0032] The moving groove 10 can be an arc-shaped groove with a low center and high sides, or a wave-shaped groove with alternating high and low sides. The moving groove 10 can have various shapes. The shape of the moving groove 10 determines the angle between the seat body 1 and the rotating shaft 7. Many shapes can be selected as needed. For example, if the moving groove 10 is an arc-shaped groove with a low center and high sides, after the rotating shaft 7 rotates, the seat body 1 will move a distance with the rotating shaft 7, but the angle between the seat body 1 and the rotating shaft 7 will always remain unchanged. Therefore, the moving groove 10 being an arc-shaped groove with a low center and high sides, or a wave-shaped groove with alternating high and low sides, is the preferred solution.

[0033] A rotating component 11 is provided on the movable component 9. The rotating component 11 can rotate around the movable component 9, and the rotating component 11 is in surface contact with the moving groove 10. The rotating component 11 reduces friction when the movable component 9 moves with the moving groove 10. In this embodiment, the rotating component 11 is a bearing.

[0034] 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 forward and reverse directions, thereby causing the rotating shaft 7 to continuously reciprocate in both forward and reverse 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 base 1 is controlled. The reduction gear set 13 is used to reduce speed and increase force. The structure is simple and the cost is low.

[0035] The rotating shaft 7 is Z-shaped, with a simple structure.

[0036] For aesthetic purposes, a drive mounting box is installed, housing the drive motor, drive motor power output unit, and one end of the rotating shaft. To ensure smoother rocking, the moving slot and moving parts are positioned away from the drive mounting box. The moving slot is placed on the base, and the moving parts are placed on the bottom. This arrangement makes the moving slot holes invisible to consumers because they face downwards, thus enhancing the overall aesthetic appeal.

[0037] The mounting box 8 also includes a movable mounting box 39 and a seat locking / unlocking part 15. The seat locking / unlocking part 15 is used to lock or unlock the seat 1 and the support frame 2. The seat locking / unlocking part 15 includes a locking pin 16, a locking hole 22 that cooperates with the locking pin 16, and a sliding block 17. It also includes a drive switch 18 and a return spring 19. The drive switch 18 is movably disposed relative to the movable mounting box 39. The locking pin 16 is movably disposed relative to the movable mounting box 39. The sliding block 17 is connected to the drive switch 18. The locking hole 22 is disposed on the movable groove 10. The sliding block 17 has a protrusion 20, and the movable part mounting box 39 has a recess 21 that mates with the protrusion 20. The sliding block 17 also has a hole for mounting a return spring 19 and a locking pin 16. When the locking pin 16 needs to mate with the locking hole 22 on the movable groove 10, the drive switch 18 drives the sliding block 17, and the protrusion 20 on the sliding block 17 disengages from the recess 21 on the movable part 9. After the sliding block 17 moves upward, the protrusion 20 on the sliding block 17 mates with the recess 21 on the movable part 9. At this time, the locking pin 16 mates with the locking hole 22 on the movable groove 10, and the seat 1 and the support frame 2 are locked. The seat locking and unlocking part 15 is located between the movable groove 10 and the movable part mounting box 39. Its advantage is that it is far away from the rotating shaft 7, thereby generating a lever arm, which makes the seat 1 more stable when fixed. The seat locking and unlocking part 15 has a more robust structure and is not easily damaged.

[0038] The seat limiting mechanism 3 includes a swing mode conversion part 23, which includes a moving groove 10 and a moving member 9. The moving groove 10 is pivotally connected to the support frame 2. It also includes a moving groove locking and unlocking device 24, which enables the moving groove 10 to be in a locked position 25 and an unlocked position 26. When the moving groove 10 is in the locked position 25, the moving groove 10 is locked relative to the support frame 2. When the moving groove 10 is in the unlocked position 26, the moving groove 10 can rotate relative to the support frame 2.

[0039] The mounting box 8 includes a movable slot mounting box 27, with the movable slot 10 pivotally connected to the movable slot mounting box 27. The movable slot mounting box 27 is fixedly connected to the support frame 2. The movable slot locking and unlocking device 24 includes a changeover switch 28 and a rising / lowering component 29. The changeover switch 28 extends into the movable slot mounting box 27 and is fixedly connected to the rising / lowering component 29. The movable slot 10 has a guide groove for the rising / lowering component 29 to move up and down. It also includes a return spring 19, with a hole for mounting the return spring 19 on the rising / lowering component 29. The return spring 19 is located between the movable slot mounting box 27 and the rising / lowering component 29. It also includes a locking pin 16 on the changeover switch 28, and a first locking hole 30 and a second locking hole 31 on the movable slot mounting box 27. When the changeover switch 28 is lifted from the first lock hole 30 and moved to the unlock position 26, the changeover switch 28 drives the moving slot 10 to rotate relative to the moving slot mounting box 27 and then fall into the second lock hole 31. The moving slot 10 and the moving slot mounting box 27 are locked. At this time, the swing mode is changed from one swing mode to another, thus realizing the swing mode conversion and enriching the entertainment needs of consumers. This swing mode conversion structure is simple, easy to operate and low in cost.

[0040] The base 14 includes a first connecting tube 32 and a second connecting tube 33, as well as a first foot tube 34 and a second foot tube 35. The first foot tube 34 and the second foot tube 35 are detachably connected to the first connecting tube 32 and the second connecting tube 33. The drive mounting box is disposed on the first connecting tube 32, and the movable component mounting box is disposed on the second connecting tube 33. The first connecting tube 32 and the second connecting tube 33 are fixedly connected. This structure overcomes the drawback of the connecting tube being prone to tilting and also achieves the advantage of a small product size by allowing the foot tubes and connecting tubes to be disassembled, thereby reducing costs.

[0041] A bearing is installed on the rotating shaft 7, and a metal sleeve 36 is installed on the bearing. The metal sleeve 36 is welded to the base 14. This design overcomes the tendency of plastic to deform, and the structure is very simple, thereby reducing costs.

[0042] A children's rocking chair includes a first bearing and a second bearing mounted on a rotating shaft 7. It also includes a first plastic part 37 that mates with the first bearing and a second plastic part 38 that mates with the second bearing. The first plastic part 37 and the second plastic part 38 are fixedly connected to a metal sleeve 36. The two bearings on the rotating shaft 7 enhance structural stability. Furthermore, the use of two plastic parts mates with the two bearings and the metal sleeve fixing the two plastic parts significantly reduces the gap between the rotating shaft 7 and the fixed sleeve, thus making the product more stable and safer.

[0043] Although the present invention has been described above with reference to embodiments, various modifications can be made to it without departing from the scope of the invention, and the invention can be implemented in other equivalent or well-known ways by those skilled in the art. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims. The terms "first" and "second" used herein are merely for distinguishing names and have no specific or actual data meaning.

[0044] This invention provides a children's rocking chair with a large swing amplitude, low cost, stable seat, and simple structure. It can also be set to two or more different swing modes, overcoming the shortcomings of existing rocking chairs on the market that have small swing amplitudes, high manufacturing requirements, and can only swing in a single mode. This invention, with its simple structure, low cost, and stable seat, is the result of long-term, meticulous research by engineers and is not something easily conceived by those skilled in the art, nor is it common knowledge.
