[0036] Embodiment 1

[0037] refer to Figure 1 As can be seen from the traditional rocking chair shown, its structure type is generally a fixed or integrated connection structure, which has the limitation of occupying a large area and being inconvenient to store and carry. Since this type of rocking chair mainly relies on the bottom arc part to achieve rocking and change the rocking amplitude by the user frequently changing the body center of gravity, it not only requires a lot of strength when rocking, but also the rocking process is relatively stiff, which has the disadvantage of lacking comfort in use. In view of this, this embodiment provides a rocking chair, reference Figure 2-7 As shown, in some of the drawings of this embodiment, the chair cloth portion on the chair will be removed first to ensure that the overall skeleton structure is displayed more clearly.

[0038] The present embodiment provides a rocking chair, comprising a chair frame and a rocking assembly 13 pivotally connected to the bottom of the chair frame. The chair frame comprises two symmetrical support frames 11 arranged side by side, and a folding assembly 12 arranged between the two support frames 11. The folding assembly 12 can make the two groups of support frames 11 move closer to each other to achieve folding or move away from each other to achieve opening. In addition, the chair frame is pivotally connected to the rocking assembly 13 via a first hinge point 1311. The rocking assembly 13 comprises a horizontally placed base 131, and the side edge of the end of the base 131 is pivotally connected to an elastic part 133 via a second hinge point 1312. The other end of the elastic part 133 is pivotally connected to the support frame 11, and is elastically fitted between the base 131 and the support frame 11 in the opposite direction of the rocking direction of the rocking chair. When the user sits on the cushion cloth 14 supported by the folding component 12 and presses his back against the position of the backrest cloth 15 so that the load-bearing center of gravity of the rocking chair is transferred from front to back, the rocking chair as a whole is tilted backward by force, and the rocking component 13 supported on its side generates elastic buffering force after being passively stressed, and its reverse force pushes and pulls the support frame 11 to realize the forward and backward rocking of the chair frame body.

[0039] The support frame 11 is composed of a "7"-shaped handrail tube and an "L"-shaped backrest tube, and the handrail tube and the backrest tube are combined to form a B-shaped support frame 11. Figure 5As shown. The handrail tube includes a handrail rod 112 and a front leg rod 113 from top to bottom, and the backrest tube includes a backrest rod 111, a rear leg rod 114 and a ground-pressing rod 115 from top to bottom, wherein the rear leg rod 114 is connected to the ground-pressing rod 115 through an arc-shaped curved tube to ensure that the support frame 11 has a larger travel space when it is shaken forward and backward along the first hinge point 1311. The folding assembly 12 arranged between the two support frames 11 includes two "U"-shaped curved tube groups with openings facing downward and hinged to each other in the middle, the lower ends of the "U"-shaped curved tube groups are respectively hinged to the lower sides of the front leg rod 113 and the rear leg rod 114 of the support frame 11, and the upper ends thereof are hinged to the middle position of the front and rear leg rods of the support frame 11 through a connecting piece 122, thereby realizing the support frame 11 to move toward each other and fold. Compared with using two rods hinged to each other in an "X" shape to fold the rocking chair body, the two U-shaped curved tubes 121 used in this embodiment are hinged to each other in an "X" shape, and the upper ends of the two sets of U-shaped curved tubes are connected by seat cushions to limit the opening and closing angles. When the rocking chair is unfolded, the connecting piece 122 and the U-shaped curved tube 121 are abutted against each other, which can improve the stability of the rocking chair frame after unfolding.

[0040] The elastic part 133 is composed of a sleeve 1330, a spring member 1331 nested in the sleeve, and a connecting rod 1332 slidably inserted at both ends of the sleeve. End plates a are provided on the end faces of the two connecting rods 1332 facing each other. In order to make the elastic part 133 elastically matched between the base 131 and the support frame 11 have better elastic potential energy, the spring member 1331 nested in the sleeve 1330 is set as a pre-tension spring in this embodiment, and the two ends of the pre-tension spring are fixed to the end plates a in the front and rear directions to achieve overall linkage. When the support frame 11 rotates along the first hinge point 1311 away from the second hinge point 1312 under the action of external force, the rocking chair is forced to tilt backward as a whole, and the connecting rod 1332 pivoted on the rear leg rod 114 extends outward with the rotation of the support frame 11 and pulls the spring member 1331 to cause it to produce elastic deformation. During the rotation process, the pre-tension spring is stretched and gradually accumulates elastic restoring force. When the external force acting on the rocking chair is removed or weakened, the pre-tension spring pulls the support frame 11 forward against the direction of the force to achieve reset. In other words, when the external force acting on the rocking chair is less than the elastic restoring force accumulated by the pre-tension spring, the pre-tension spring retracts and releases elastic energy, and with the help of the shock-absorbing effect of the spring body, the rocking chair is pulled to shake, achieving the effect of rocking the rocking chair back and forth at a certain frequency.

[0041] Embodiment 2

[0042] refer to Figure 8-Figure 9The main difference between this embodiment and the first embodiment is that the rocking assembly 13 described in this embodiment not only includes a base 131 and an elastic part 133, but also includes a height adjustment mechanism 132 connected between the base 131 and the elastic part 133. The height adjustment mechanism 132 includes a first adjustment rod 1321 and a second adjustment rod 1322 that are slidably nested. One end of the first adjustment rod 1321 is fixed to the base 131, and the end of the second adjustment rod 1322 away from the first adjustment rod 1321 is rotatably connected to the elastic part 133 through a second hinge point 1312. This embodiment mainly adjusts the length of the force arm acting on the elastic part 133 by the relative sliding of the first adjustment rod 1321 and the second adjustment rod 1322. In other words, the height adjustment mechanism 132 described in this embodiment can be used to meet the needs of adaptively adjusting the height of the telescopic rod according to the weight of the user to improve the comfort of the rocking chair. Specifically, when the user is light, the height of the height adjustment mechanism 132 can be increased to shorten the lever arm and reduce the torque, ensuring that the user can easily pull the spring member with only a small force to achieve the rocking function of the rocking chair body. Correspondingly, when the user is heavy, the height of the height adjustment mechanism 132 can be lowered to increase the lever arm, and the elastic force of the spring member 1331 can be increased by increasing the torque, so as to avoid the structural damage and functional failure caused by the unbalanced force on the spring member. The height adjustment mechanism can be used to adaptively adjust the torque to effectively maintain the reliability and durability of the structure.

[0043] Embodiment 3

[0044] refer to Fig.10 The main difference between this embodiment and the first embodiment lies in the internal connection structure of the elastic part 133. Specifically, the elastic part 133 described in this embodiment includes a sleeve 1330, a spring member 1331 nested in the sleeve, and a connecting rod 1332 penetrating the spring member 1331 and slidingly arranged in the sleeve 1330. The connecting rod 1332 is provided with an end plate a supporting the spring member 1331. When the support frame 11 rotates along the first hinge point 1311 toward away from the second hinge point 1312, the rocking chair tilts backward and drives the connecting rod 1332 pivoted on the rear support leg rod 114 to extend outward. The connecting rod 1332 extends outward and drives the end plate a to radially squeeze the spring member 1331. In order to make the elastic part 133 elastically fitted between the base 131 and the support frame 11 have better elastic potential energy, the spring member 1331 nested in the sleeve 1330 in this embodiment is set as a pre-stressed spring. The pre-stressed spring is deformed under pressure to accumulate elastic restoring force, and pulls the support frame 11 forward against the rocking direction of the chair frame to achieve restoration.
