Description

Technical Field

[0001] The utility model relates to the field of seats, in particular to a swing connection mechanism and a chair. Background Art

[0002] A chair typically refers to a reclining chair used for resting. Many people often experience fatigue and soreness during this rest period, primarily due to the limitations of existing office chairs. While traditional office chairs typically feature backrests, they often remain locked during use, resulting in a lack of back mobility during extended periods of sitting, leading to fatigue and discomfort. Therefore, rocking chairs have emerged to provide greater comfort.

[0003] However, existing rocking joints are typically designed for chairs of specific shapes. When the chair model or shape changes, the rocking joint structure must be adjusted accordingly. This lack of flexibility in shape and functionality limits its applicability and creates inconvenience for users. Therefore, developing a more versatile and adaptable rocking joint structure is crucial. Utility Model Content

[0042] Reference Figure 1-Figure 3 The basic embodiment of the first aspect of the present invention provides a swing connection mechanism, comprising:

[0043] Housing 100;

[0044] The rocker 200 is rotatably mounted on the housing 100;

[0045] The elastic return member 300 is disposed in the housing 100 , with one end of the elastic return member 300 connected to the housing 100 and the other end connected to the rocker 200 . The elastic return member 300 is driven by elastic force to rotate the rocker 200 in a direction away from the elastic return member 300 .

[0046] According to the embodiments of the present invention, by such an arrangement, at least some of the following effects can be achieved: the shell 100 can be fixedly installed on the seat 400 or the armrest, one end of the rocker 200 is rotatably connected to the shell 100, and the other end of the rocker 200 is fixedly connected to the chair back 500. When the user leans on the chair back 500, the chair back 500 will press down to rotate the rocker 200. When driven by the elastic return member 300, the rocker 200 returns to its original position, so that the chair back 500 can move and adapt to changes in human body pressure; only one end of the rocker 200 needs to be rotated to connect to the shell 100, and the other end of the rocker 200 is fixedly connected to the chair back 500. The shell 100, the rocker 200, and the elastic return member 300 can be used separately as a whole, and can be installed on chairs of different sizes and models, so that the chair back 500 has a rocking function and is highly applicable.

[0047] In some embodiments, the housing 100 is provided with a guide slot 110, which is arranged along the rotation direction of the rocker 200. The rocker 200 is provided with a guide portion 210, which slides along the guide slot 110. The guide slot 110 guides the rotation of the rocker 200, allowing the rocker 200 to move along the rotation direction. Furthermore, the guide portion 210 is slidably connected to the guide slot 110, providing support for the guide portion 210, thereby improving the bearing capacity of the chair back 500 and enhancing the overall stability of the chair.

[0048] In some embodiments, the rocker 200 includes a rotating portion 220 and a connecting portion 230. The connecting portion 230 is disposed on the rotating portion 220, which is disposed on the housing 100. The connecting portion 230 is L-shaped. The rotating portion 220 is used to enable the chair back 500 to rock. The L-shaped connecting plate can connect the two surfaces of the chair back 500, increasing the contact area between the rocker 200 and the chair back 500, thereby improving the load-bearing capacity and stability of the chair.

[0049] In some embodiments, the connection portion 230 includes a side mounting plate and a back mounting plate. The side mounting plates are used to connect to the sides of the chair back 500, and the back mounting plate is used to connect to the back of the seat 400. The L-shaped connection portion 230 is used to connect the side and back of the chair back 500. When a user leans on the chair back 500, the back mounting plate can withstand the pressure applied by the user to the chair back 500, thereby improving the load-bearing capacity of the chair.

[0050] In some embodiments, the side mounting plates and / or the back mounting plates are provided with mounting holes, through which screws are used to mount the rocker 200 on the chair back 500 for ease of installation and use.

[0051] In some embodiments, the rocker arm 200 is partially located within the housing 100 and partially extends outside the housing 100. The housing 100 is provided with an extension slot 120, through which the rocker arm 200 passes. The rocker arm 200 allows for a portion of the rocker arm 200 to be located within the housing 100 and a portion to extend outside the housing 100. The internally mounted structure prevents the rocker arm 200 from detaching from the housing 100. The housing 100 provides support, thereby increasing the rocker arm's load-bearing capacity.

[0052] In some embodiments, the elastic return member 300 includes a pressing block and a spring, and the spring is driven by elastic force to move the pressing block toward the rocker 200. The spring drives the pressing block to abut against the rocker 200, so that the rocker 200 has a rocking function.

[0053] In some embodiments, the width of the rocker 200 gradually increases from the center of rotation toward the direction away from the center. A smaller width of the rocker 200 and a smaller center of rotation of the rocker 200 can reduce the volume of the housing 100 and the size of the rotation axis, thereby reducing costs. A larger width away from the center can increase the contact area between the rocker 200 and the chair back 500, thereby improving stability.

[0054] The basic embodiment of the second aspect of the present invention provides a chair, comprising:

[0055] Seat 400;

[0056] The rocking connection mechanism, the housing 100 is provided on the seat 400;

[0057] The chair back 500 is provided on the rocker 200 .

[0058] According to the embodiment of the present invention, by such a configuration, at least the following effects can be achieved: the housing 100 can be fixedly mounted on the seat 400 or the armrest, one end of the rocker 200 is rotatably connected to the housing 100, and the other end of the rocker 200 is fixedly connected to the chair back 500. When the user leans on the chair back 500, the chair back 500 presses down to rotate the rocker 200. When driven by the elastic reset member 300, the rocker 200 returns to its original position, so that the chair back 500 can move and adapt to changes in human body pressure; through the rocker 200 Part of the structure of the rocker arm 200 can be arranged inside the shell 100, and part of the structure can extend outside the shell 100. The structure installed inside can prevent the rocker arm 200 from separating from the shell 100; only one end of the rocker arm 200 needs to be rotated to connect to the shell 100, and the other end of the rocker arm 200 is fixedly connected to the chair back 500. The shell 100, the rocker arm 200, and the elastic return member 300 can be used separately as a whole and can be installed on chairs of different sizes and models, so that the chair back 500 has a rocking function and is highly applicable.

[0059] In some embodiments, at least two rocking connection mechanisms are provided. Providing two rocking connection mechanisms on both sides can improve the load-bearing capacity of the chair back 500 and enhance stability.

[0060] Furthermore, the back of the seat 400 may also be provided with a rocking connection mechanism to improve the load-bearing capacity of the chair.
