Description

Technical Field

[0001] This utility model relates to the field of baby product technology, and in particular to a shock absorption mechanism for a children's rocking chair and the children's rocking chair itself. Background Technology

[0002] Some simple children's rocking chairs on the market consist only of a rocker arm and a backrest, which are fixedly connected at one point. However, because the materials usually have some elastic deformation, in addition to back-and-forth rocking, the child's footsteps also cause up-and-down swaying. Since there is no additional support, if the force is too great or the child is too heavy, the up-and-down swaying amplitude is too large, which can easily lead to tipping over or the backrest breaking, causing injury to the child. To address this, a children's rocking chair has appeared on the market, as shown in patent document CN205947532U. It includes a rocker arm, a backrest, and a support rod. The support rod is used to support the rocker arm and backrest at a specified angle. The support rod plays a fixing role, so that the backrest and rocker arm will not swing relative to each other. However, this cannot satisfy the child's enjoyment of swaying when sitting on it. Therefore, a shock-absorbing mechanism for children's rocking chairs needs to be designed to replace the support rod, so that the rocking chair with this mechanism can not only realize the rocking function, but also have up-and-down swaying, while limiting the amplitude of the up-and-down swaying.

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0019] Please see Figures 1 to 2 A shock-absorbing mechanism for a children's rocking chair includes a guide sleeve 1 and a telescopic sleeve 2. The telescopic sleeve 2 is telescopically mounted on the guide sleeve 1. A reset member 3 is provided between the guide sleeve 1 and the telescopic sleeve 2. A limiting member 4 is also provided between the side walls of the guide sleeve 1 and the telescopic sleeve 2 that are in contact, for limiting the telescopic range of the telescopic sleeve 2 relative to the guide sleeve 1. A connecting cylinder 5 is provided at the end of the guide sleeve 1 away from the telescopic sleeve 2, and a connecting cylinder 5 is also provided at the end of the telescopic sleeve 2 away from the guide sleeve 1. The connecting cylinder 5 is used to connect a rocker arm 9 or a backrest arm 10. Through the telescopic cooperation of guide sleeve 1 and telescopic sleeve 2, and in conjunction with reset component 3, the rocker arm 9 and backrest arm 10 of the rocker chair with this shock absorption mechanism can swing relative to each other (achieving both the forward and backward swing of a normal rocker chair and the up and down swing, making it more fun). Furthermore, a limiting component 4 is provided between telescopic sleeve 2 and guide sleeve 1 to limit the relative displacement of telescopic sleeve 2 and guide sleeve 1, which limits the swing amplitude of backrest arm 10 relative to rocker arm 9, thus avoiding the risk of tipping over and breaking, and protecting children.

The sliding cooperation between the limiting groove 41 and the limiting block 42 ensures the reliability of displacement range control through mechanical limiting. In a preferred embodiment, the limiting groove 41 is disposed in the side wall of the telescopic sleeve 2.

[0021] Please see Figures 1 to 2 Preferably, the limiting block 42 is a limiting pin, which penetrates the sidewalls of the telescopic sleeve 2 and the guide sleeve 1. The limiting groove 41 is axial in the limiting direction. When the limiting groove 41 is located on the sidewall of the telescopic sleeve 2, it penetrates the telescopic sleeve 2 radially, and the limiting pin passes through the telescopic sleeve 2 via the limiting groove 41. When the limiting groove 41 is located on the sidewall of the guide sleeve 1, it penetrates the guide sleeve 1 radially, and the limiting pin passes through the guide sleeve 1 via the limiting groove 41. The design of the limiting pin penetrating the telescopic sleeve 2 and the guide sleeve ensures uniform force distribution and avoids increased wear caused by unilateral force distribution.

[0022] Please see Figures 1 to 2Preferably, when the limiting groove 41 is provided on the side wall of the telescopic sleeve 2, one end of the reset member 3 is axially limited and engaged with the telescopic sleeve 2, and the other end of the reset member 3 is axially limited and engaged with the limiting block 42; when the limiting groove 41 is provided on the guide sleeve 1, one end of the reset member 3 is axially limited and engaged with the guide sleeve 1, and the other end of the reset member 3 is axially limited and engaged with the limiting block 42.

When the limiting groove 41 is provided on the side wall of the telescopic sleeve 2, the top abutment 6 is fixed inside the telescopic sleeve 2 and abuts against one end of the reset member 3; when the limiting groove 41 is provided on the guide sleeve 1, the top abutment 6 is fixed inside the guide sleeve 1 and abuts against one end of the reset member 3. The dedicated top abutment 6 ensures that the end face of the reset member 3 is evenly stressed, and the fixed top abutment design prevents axial displacement of the reset member 3, improves the working stability of the elastic element, and extends its service life.

[0024] Please see Figures 1 to 2 Preferably, the reset member 3 is a spring, and the abutting member 6 includes an abutting block 61 and a connecting post 62. The connecting post 62 is fixed on the abutting block 61, and the spring is sleeved on the connecting post 62. When the limiting groove 41 is provided on the side wall of the telescopic sleeve 2, the abutting block 61 is fixed inside the telescopic sleeve 2 and abuts against one end of the spring. When the limiting groove 41 is provided on the guide sleeve 1, the abutting block 61 is fixed inside the guide sleeve 1 and abuts against one end of the reset member 3. The structural design of the spring sleeved on the connecting post 62 provides a precise guiding function, ensuring linear compression of the spring and preventing the spring from bending and becoming unstable.

[0025] Please see Figures 1 to 2 Preferably, the connecting cylinder 5 is provided at the opposite ends of the guide sleeve 1 and the telescopic sleeve 2. The connecting cylinder 5 has a skirt that engages with the end face of the guide sleeve 1 or the telescopic sleeve 2 for positioning. A pin 7 is provided between the side wall of the guide sleeve 1 and the corresponding side wall of the connecting cylinder 5, and a pin 7 is provided between the side wall of the telescopic sleeve 2 and the corresponding side wall of the connecting cylinder 5. When the limiting groove 41 is provided on the side wall of the telescopic sleeve 2, the abutting block 61 abuts against the inner end face of the connecting cylinder 5 passing through the telescopic sleeve 2. When the limiting groove 41 is provided on the guide sleeve 1, the abutting block 61 abuts against the inner end face of the connecting cylinder 5 passing through the guide sleeve 1. The skirt positioning of the connecting cylinder 5 and the fixing with the pin 7 achieve double positioning protection, and the abutting block 61 abuts against the inner end face of the connecting cylinder 5 to form a stable force transmission path. The split-type connecting cylinder 5 design facilitates the adaptation and modification of rocking chairs of different specifications.

[0026] Please seeFigures 1 to 2 Preferably, the connecting cylinder 5 is hinged to the rocker arm 9 or the backrest arm 10, and the rocker arm 9 and the backrest arm 10 are provided with hinge seats at corresponding positions. The hinged connection method adapts to the angle changes during the movement of the rocking chair, and the connecting cylinder 5 can be adapted to various models of rocking chairs, as long as the rocker arm 9 and the backrest arm 10 of the rocking chair are provided with matching connecting seats 8, which has good versatility. The end face of the connecting cylinder opposite to the connecting seat 8 is designed as an arc surface, and the connecting seat 8 is also provided with an arc groove for the telescopic sleeve 2 or the guide sleeve 1 to rotate.

[0027] Please see Figure 3 A children's rocking chair includes a rocker arm 9 and a backrest rod 10. A shock-absorbing mechanism as described above is provided on the included angle side of the rocker arm 9 and the backrest rod 10. A connecting cylinder 5 on the telescopic sleeve 2 is hinged to either the rocker arm 9 or the backrest rod 10. The connecting cylinder 5 on the guide sleeve 1 is also hinged to either the backrest rod 10 or the rocker arm 9. A connecting seat 8 can be hinged to the corresponding backrest rod 10 or rocker arm 9 by bolts or ultrasonic welding.

[0028] The working principle of this utility model is as follows:

[0029] The backrest rod 10 or rocker arm 9 transmits external force to the telescopic sleeve 2 or guide sleeve 1 through the connecting seat 8 and connecting cylinder 5. The external force acts on the telescopic sleeve 2 or guide sleeve 1, and the telescopic sleeve 2 or guide sleeve 1 moves closer to each other in relative displacement. The limiting block 42 slides relative to the limiting groove 41 and moves towards the top abutment block 61, and transmits the force to the spring through the top abutment block 61. The spring is compressed and deformed until the limiting block 42 abuts against the end face of the limiting groove 41 (the end closest to the top abutment block 61), and the backrest rod 10 and rocker arm 9 can no longer approach each other (achieving the effect of limiting the swing amplitude). When the external force is less than the spring's restoring force (the stress sufficient for the spring to return to its initial state), the spring pushes the limiting block 42 along the limiting groove 41 away from the top abutment block 61 until the limiting block 42 abuts against the end of the limiting groove 41 away from the top abutment block 61 and stops.
