The base 200 may be made of a sturdy and durable material such as metal, wood, or plastic. In this embodiment, the base 200 is designed to have a structure with a certain weight, so as to increase the stability of the rocking chair, prevent the rocking chair from falling over during use, and will not be described in detail herein.

Structure for driving swing rod group 400

The driving swing link group 400 is a key component connecting the chair frame 100 and the base 200, and enables the chair frame 100 to perform a swinging motion on the base 200. The driving swing link group 400 includes a pair of first swing links 410 spaced apart in the width direction of the swing chair. The pair of first swing rods 410 are hinged to the front ends of the base 200, respectively, and are hinge-coupled with the first swing portion 110 of the chair frame 100. In addition, the driving swing link group 400 further includes a pair of second swing links 420, and the pair of second swing links 420 are configured as follower swing links, which are respectively hinged at the rear end of the base 200 and are hinge-coupled with the second swing 120 of the chair frame 100.

It should be noted that in other embodiments, the first swing link 410 may also be disposed at the rear end of the base, and connected to the swing driving device, so as to implement an active swing portion for free swing and motor driven swing. Further, the second swing rod 420 may be hinged to the front end of the base and may swing along with the active swing portion, so as to realize a stable swing motion, which will not be described herein in detail.

Structure of swing driving device 300

Referring to fig. 4, the swing driving apparatus 300 is a key component for implementing the electric swing mode of the swing chair. It includes a motor 310, a friction shaft 320 driven by the motor 310, and a friction bar 330 in frictional contact with the friction shaft 320. The motor 310 is fixed to the base 200 and connected to 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 with a surface having a certain roughness to increase friction with the friction bar 330.

The friction bar 330 includes a mounting portion 331 fixedly coupled to the transverse bar 500 and a friction portion 332 adapted to be held in frictional contact with the swing drive 300. The mounting portion 331 is fixedly coupled to the transverse bar 500 by welding, bolting or other fastening means, and the transverse bar 500 is coupled to the chair frame 100 by a pair of first swing arms 410. The friction portion 332 is configured as a rubber member having a surface with a certain elasticity and roughness to increase friction and wear resistance with the friction shaft 320.

Implementation of free-swing and electric-swing modes

Under the power of the user, that is, when the user shakes the body back and forth, the chair frame 100 drives the transverse rod 500 and the friction bar 330 to move together by driving the swing rod group 400. At this time, the friction portion 332 of the friction bar 330 slides against the friction shaft 320, thereby realizing the free rocking mode of the chair frame 100. In this mode, the user can control the rhythm and amplitude of the rocking according to his/her own preference and physical condition.

Under the power of the motor, i.e., when the motor 310 is started, it drives the friction shaft 320 to rotate through the transmission mechanism. Because of the friction between the friction shaft 320 and the friction portion 332 of the friction bar 330, rotation of the friction shaft 320 will move the friction bar 330 and the transverse bar 500 together. Further, the chair frame 100 is driven to perform a swinging motion on the base 200 through the transmission action of the pair of first swinging rods 410 and the pair of second swinging rods 420, so that an electric swinging mode is realized. In this mode, the user can easily enjoy the rocking by controlling the switching and rocking speed of the motor 310 through a simple operation without applying any force.

It should be noted that, the swing chair of the present utility model realizes seamless switching between two modes of free swing and electric swing by smart design of the driving swing rod group 400 and the swing driving device 300. The user can select a swinging mode suitable for the user according to the user's preference and physical condition, and enjoy more comfortable and convenient swinging experience. Meanwhile, the stability and comfort of the rocking chair are further improved through innovation points such as the design of the elastic member 350 and the arc-shaped surface, so that the rocking chair has stronger competitiveness and application value in the market.

Elastic supporting structure of swing driving device 300

Referring to fig. 5, in order to further improve stability and comfort of the swing chair, the swing driving apparatus 300 further includes a housing 340 and an elastic member 350. The housing 340 serves to accommodate the motor 310, the friction shaft 320, and the like, and protect them from the external environment. The elastic member 350 is used for rotatably pivoting the housing 340 on the base 200 and providing a certain elastic supporting force for the swing driving device 300.

Specifically, the elastic member 350 includes a pivot seat 351, a pivot shaft 352, and a spring member 353. The pivot base 351 is fixed to the base 200, and the pivot shaft 352 is installed on the pivot base 351 through the housing 340 such that the housing 340 can rotate about the pivot shaft 352. The spring member 353 is mounted to the pivot shaft 352 with its two legs bearing against the housing 340 and the base 200, respectively. Providing upward resilient support to the housing 340. The elastic support structure enables the swing driving device 300 to maintain a certain stability and buffer effect in the swing process, and reduces impact force and noise generated by swing.

Design of contact surface between friction part 332 and friction shaft 320

To further optimize the rocking performance and comfort of the rocking chair, the abutting surface of the friction portion 332 and the friction shaft 320 is designed to be an arc-shaped surface. This arcuate surface design allows the friction portion 332 and the friction shaft 320 to more closely conform together when in contact, increasing friction and transmission efficiency therebetween. The elastic member 350 is mounted to the housing and the base 200 to maintain the movable tendency of the friction shaft 320 to abut against the arc surface. Meanwhile, the design of the arc-shaped surface can be adjusted and optimized according to the swing stroke of the swing chair, so that the swing chair is smoother and more stable in the swing process.

Specifically, the curvature and length of the arc surface can be designed according to the swing angle and amplitude of the rocking chair. For example, when the swing angle of the swing chair is large, the arc surface may be designed to have a large curvature and a long length to increase the contact area and friction between the friction part 332 and the friction shaft 320, and when the swing angle of the swing chair is small, the arc surface may be designed to have a small curvature and a short length to reduce friction and power consumption.

It should be understood that the embodiments that the application may employ are not limited thereto. In other embodiments, to increase the rolling friction between the friction shaft 320 and the friction bar 330, the friction bar 330 may have a more convex structure or employ a more friction material as a member of the friction portion. In other embodiments, the spring member 353 can be an extension spring, and the connection manner of the extension spring, the housing and the base can be adjusted, so that the extension spring can be restored by compression or extension, and the friction shaft 320 can be always abutted against the friction strip 330. Unlike the above embodiments, the roller is located at the lower side of the arc-shaped driven surface, and in other embodiments, the arc-shaped driven surface can be adjusted to be the upper side of the friction strip 330, and the roller can be located at the upper side of the arc-shaped driven surface, which will not be repeated herein.

The foregoing is merely illustrative of the present utility model, and the present utility model is not limited thereto, and any changes or substitutions easily contemplated by those skilled in the art within the scope of the present utility model should be included in the present utility model. Therefore, the protection scope of the utility model is subject to the protection scope of the claims.
