[0043] The base 200 serves as the support for the rocking chair, providing stable support for the chair frame 100 and the rocking drive device 300. The base 200 can be made of sturdy and durable materials, such as metal, wood, or plastic. In this embodiment, the base 200 is designed with a certain weight to increase the stability of the rocking chair and prevent it from tipping over during use; further details are omitted here.

[0044] Structure of the drive rocker arm assembly 400

[0045] The driving swing lever set 400 is a key component connecting the chair frame 100 and the base 200, which enables the chair frame 100 to swing on the base 200. The driving swing lever set 400 includes a pair of first swing levers 410 arranged at intervals in the width direction of the rocking chair. The pair of first swing levers 410 are respectively hinged at the front end of the base 200 and hingedly cooperated with the first swing part 110 of the chair frame 100. In addition, the driving swing lever set 400 further includes a pair of second swing levers 420, which are configured as follow-up swing levers and are respectively hinged at the rear end of the base 200 and hingedly cooperated with the second swing part 120 of the chair frame 100. The cooperation of the first swing levers 410 and the second swing levers 420 enables the chair frame 100 to stably swing in the front-rear direction. It should be noted that in other embodiments, the first swing levers 410 can also be arranged at the rear end of the base and connected with the swing driving device, thereby realizing the active swing part of the free swing and the motor-driven swing. Further, the second swing levers 420 can be hinged at the front end of the base and swing with the active swing part, thereby realizing the stable swing, which will not be described in detail here.

[0046] Structure of the swing driving device 300

[0047] Please refer to Figure 4 The swing driving device 300 is a key component for realizing the motor-driven swing mode of the rocking chair. It includes a motor 310, a friction shaft 320 driven by the motor 310, and a friction strip 330 in friction contact with the friction shaft 320. The motor 310 is fixed on the base 200 and connected with the friction shaft 320 through a transmission mechanism, for driving the friction shaft 320 to rotate. The friction shaft 320 is rotatably positioned on the base 200, and its surface has a certain roughness to increase the friction force between the friction shaft 320 and the friction strip 330.

[0048] The friction strip 330 includes a mounting part 331 fixed to the transverse rod 500 and a friction part 332 adapted to maintain friction contact with the swing driving device 300. The mounting part 331 is fixed to the transverse rod 500 by welding, bolting or other fixing methods, and the transverse rod 500 is connected with the chair frame 100 through the pair of first swing levers 410. The friction part 332 is configured as a rubber member, and its surface has a certain elasticity and roughness to increase the friction force and wear resistance between the friction shaft 320 and the friction strip 330.

[0049] Realization of the free swing mode and the motor-driven swing mode

[0050] Under the power of the user, that is, when the user swings his body back and forth, the chair frame 100 moves the transverse rod 500 and the friction strip 330 together through the driving of the swing lever set 400. At this time, the friction part 332 of the friction strip 330 slips between the friction shaft 320 to overcome the friction force, thereby realizing the free swing mode of the chair frame 100. In this mode, the user can control the rhythm and amplitude of the swing according to his own preferences and physical conditions.

[0051] Under the power of the motor, that is, when the motor 310 is started, it drives the friction shaft 320 to rotate through the transmission mechanism. Because of the friction force between the friction shaft 320 and the friction part 332 of the friction strip 330, the rotation of the friction shaft 320 drives the friction strip 330 and the transverse rod 500 to move together. In turn, through the transmission action of a pair of first swing levers 410 and a pair of second swing levers 420, the chair frame 100 is driven to swing on the base 200, realizing its electric swing mode. In this mode, the user does not need to exert any force, but only needs to control the switch and swing speed of the motor 310 through simple operation, to easily enjoy the swing pleasure.

[0052] It should be noted that the rocking chair of the utility model realizes seamless switching between the free swing and electric swing modes through the ingenious design of the driving swing lever set 400 and the swing driving device 300. The user can choose the swing mode suitable for himself according to his own preferences and physical conditions, and enjoy a more comfortable and convenient swing experience. At the same time, the utility model further improves the stability and comfort of the rocking chair through the innovative points such as the elastic member 350 and the arc-shaped surface design, so that it has stronger competitiveness and application value in the market.

[0053] The elastic support structure of the swing driving device 300

[0054] Please refer to Figure 5 In order to further improve the stability and comfort of the rocking chair, the swing driving device 300 further comprises a shell 340 and an elastic member 350. The shell 340 is used to accommodate the motor 310, the friction shaft 320 and other components, and to protect them from the interference of the external environment. The elastic member 350 is used to pivotably connect the shell 340 on the base 200, and to provide a certain elastic support force for the swing driving device 300.

[0055] Specifically, the elastic member 350 includes a pivot seat 351, a pivot shaft 352, and a spring piece 353. The pivot seat 351 is fixed on the base 200, the pivot shaft 352 is installed on the pivot seat 351 through the shell 340, so that the shell 340 can rotate around the pivot shaft 352. The spring piece 353 is installed on the pivot shaft 352, and its two feet are respectively on the shell 340 and the base 200. The shell 340 is provided with an upward elastic supporting force. This elastic supporting structure enables the rocking driving device 300 to maintain a certain stability and buffering effect during rocking, reducing the impact force and noise generated by rocking.

[0056] The design of the contact surface of the friction part 332 and the friction shaft 320

[0057] In order to further optimize the rocking performance and comfort of the rocking chair, the contact surface of the friction part 332 and the friction shaft 320 is designed as an arc surface. This arc surface design enables the friction part 332 and the friction shaft 320 to be more closely attached when in contact, increasing the friction force and transmission efficiency between them. The elastic member 350 is installed on the shell and the base 200 to keep the friction shaft 320 in the active tendency of being attached to the arc surface. At the same time, the design of the arc surface can also be adjusted and optimized according to the rocking stroke of the rocking chair, so that the rocking chair is more smooth and stable during rocking.

[0058] Specifically, the curvature and length of the arc surface can be designed according to the rocking angle and amplitude of the rocking chair. For example, when the rocking angle of the rocking chair is large, the arc surface can be designed with large curvature and long length to increase the contact area and friction force between the friction part 332 and the friction shaft 320; when the rocking angle of the rocking chair is small, the arc surface can be designed with small curvature and short length to reduce the friction force and energy consumption.

[0059] It should be understood that the embodiments that can be employed by the present application are not limited thereto. In other embodiments, to increase the rolling friction force between the friction shaft 320 and the friction strip 330, the friction strip 330 can have more protruding structures or adopt a material with greater friction force as the component of the friction part. In other embodiments, the spring piece 353 can be adjusted as a telescopic spring, and by adjusting the connection mode of the telescopic spring with the shell and the base, the telescopic spring can always be attached to the friction strip 330 by compression reset or extension reset. Unlike the aforementioned embodiment in which the roller is located on the lower side of the arc driven surface, in other embodiments, the arc driven surface can also be adjusted to the upper side of the friction strip 330, and the roller can be located on the upper side of the arc driven surface, which will not be described in detail here.

[0060] The above merely describes a specific implementation of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
