[0045] See also Figure 1 and Figure 5 An electric rocking chair frame based on elastic traction includes a base 1, a seat frame 2, a rocking assembly 3, a roaming drive mechanism 4 and an elastic traction group 5. The base 1 is used to be directly placed on the ground for load bearing, and serves as the carrier part of the entire electric rocking chair. There are two groups of rocking assemblies 3, and the two groups of rocking assemblies 3 have the same structure and are symmetrically installed on the base 1. The left and right sides of the seat frame 2 are respectively installed on the two groups of rocking assemblies 3, and the seat frame 2 is suspended relative to the base 1, so the seat frame 2 can swing back and forth relative to the base 1. The roaming drive mechanism 4 is installed on the base 1, which is used to output power to drive the seat frame 2 to swing. One end of the elastic traction group 5 is connected to the base 1, and the other end is connected to the seat frame 2; or one end of the elastic traction group 5 is connected to the roaming drive mechanism 4, and the other end is connected to the seat frame 2. When the Xiaoyao driving mechanism 4 is in operation, it can drive the elastic traction group 5 to produce elastic stretching. Since one end of the elastic traction group 5 is connected to the seat frame 2, the elastic traction group 5 can pull the seat frame 2 to swing relative to the base 1 when the elastic stretching is produced. When the Xiaoyao driving mechanism 4 does not apply force to the elastic traction group 5, the elastic traction group 5 can use its own resilience to pull the seat frame 2 to swing relative to the base 1 in the rebound direction, and finally realize the electric control of the rocking chair. Of course, the Xiaoyao driving mechanism 4 can also be set to apply different forces to the elastic traction group 5, so that the elastic traction group 5 can pull the seat frame 2 to swing relative to the base 1 in different directions when elastic deformation occurs, and finally realize the rocking of the rocking chair.

[0046] In this technical solution, a swing drive mechanism 4 is installed on the base 1, and the swing drive mechanism 4 drives the elastic traction group 5 to produce elastic stretching, so as to pull the seat frame 2 to swing back and forth relative to the base 1. Compared with the traditional structure using a transmission belt plus an eccentric wheel or a friction pair plus a pressure mechanism, the electric rocking chair frame structure of this technical solution is simpler and has a lower manufacturing cost. In addition, the elastic traction group 5 is used to produce a traction effect on the seat frame 2 when elastic deformation occurs, so that the seat frame 2 can swing more smoothly, without jamming and with less noise, and the rebound of the elastic traction group 5 after elastic deformation can also pull the seat frame 2 to swing.

[0047] Embodiment 1

[0048] See also Figures 1 to 4 , the Xiaoyao driving mechanism 4 includes a Xiaoyao driving motor 41, and the elastic traction group 5 includes a first elastic member 51. The Xiaoyao driving motor 41 is installed on the base 1, and one end of the first elastic member 51 is connected to the seat frame 2, and the other end is connected to the output end of the Xiaoyao driving mechanism 4. The output end of the Xiaoyao driving motor 41 rotates, which can drive one end of the first elastic member 51 to rotate, so that the first elastic member 51 is subjected to a tensile force, and then the first elastic member 51 is elastically deformed; when the first elastic member 51 is elastically deformed, there is a pulling force on the seat frame 2, pulling the seat frame 2 to swing relative to the base 1. After the output end of the Xiaoyao driving motor 41 rotates a certain angle or number of circles, the seat frame 2 swings to a certain extent relative to the base 1; then the output end of the Xiaoyao driving motor 41 is controlled to rotate in the opposite direction, so that the seat frame 2 swings in the opposite direction relative to the base 1; this is repeated to achieve the reciprocating swing of the seat frame 2. Of course, after the seat frame 2 swings to a certain extent relative to the base 1, the swing drive motor 41 can be controlled not to do work; at this time, due to the action of the swing assembly 3 and the seat frame 2 (reset to the initial state), the seat frame 2 can swing in the opposite direction and tend to reset to the initial state; this can be repeated to achieve the reciprocating swing of the seat frame 2. The combination of the swing drive motor 41 and the first elastic member 51 can realize the electric control swing of the rocking chair, with a simple structure, and the elastic deformation of the first elastic member 51 is used to make the swinging process smoother.

[0049] Specifically, see Figure 4 The first elastic member 51 includes a tension spring 511 and a belt 512. One end of the tension spring 511 is connected to the output end of the Xiaoyao drive motor 41. The other end is connected to one end of the belt 512, and the other end of the belt 512 is connected to the seat frame 2. That is, the first elastic member 51 is composed of a tension spring 511 and a belt 512 connected end to end. During the swinging process of the traction seat frame 2, the elastic deformation mainly occurs on the tension spring 511, and the belt 512 hardly undergoes elastic deformation. With such a configuration, the large elastic deformation capacity and rebound reset capacity of the tension spring 511 itself can be effectively utilized. In addition, the belt 512 can be used to better transfer the pulling force to the seat frame 2 to ensure that the seat frame 2 can be pulled to swing. Therefore, the elastic traction group 5 can be composed of conventional parts and components, with a simple structure and low manufacturing cost.

[0050] Of course, in other embodiments, one end of the tension spring 511 may be connected to the seat frame 2 and the other end may be connected to the belt 512 , and the other end of the belt 512 may be connected to the output end of the Xiaoyao driving motor 41 .

[0051] As mentioned above, the elastic traction group 5 can also achieve the swing of the traction frame 2 when it is composed only of the first elastic member 51. Figure 4, the elastic traction group 5 may also include a second elastic member 52, that is, the elastic traction group 5 is composed of a first elastic member 51 and a second elastic member 52. One end of the first elastic member 51 is connected to the front lower end of the seat frame 2, and the other end is connected to the output end of the Xiaoyao driving motor 41, and one end of the second elastic member 52 is connected to the rear end of the seat frame 2, and the other end is connected to the output end of the Xiaoyao driving motor 41. The Xiaoyao driving motor 41 is approximately located in the middle position of the base 1, the first elastic member 51 connects the front end of the seat frame 2 and the output end of the Xiaoyao driving motor 41, and the second elastic member 52 connects the rear end of the seat frame 2 and the output end of the Xiaoyao driving motor 41. In the front-to-back direction, the first elastic member 51 and the second elastic member 52 are not in the same horizontal plane, so when viewed from the side, the first elastic member 51 and the second elastic member 52 extend from front to back and from bottom to top. When the Xiaoyao driving motor 41 is in operation, the output end of the Xiaoyao driving motor 41 rotates, driving one end of the first elastic member 51 and the second elastic member 52 to rotate, so that the first elastic member 51 and the second elastic member 52 are subjected to a tensile force, and then the first elastic member 51 and the second elastic member 52 are elastically deformed; when the first elastic member 51 and the second elastic member 52 are elastically deformed, they both exert a pulling force on the seat frame 2. Since these two forces are not in the same horizontal plane, the seat frame 2 can be pulled to swing relative to the base 1. Then the output end of the Xiaoyao driving motor 41 is controlled to rotate in the opposite direction, so that the seat frame 2 swings in the opposite direction relative to the base 1; this is repeated to achieve the reciprocating swing of the seat frame 2. It should be noted that even if the Xiaoyao driving motor 41 drives the first elastic member 51 and the second elastic member 52 to pull the seat frame 2 with a small amplitude, when it is transmitted to the upper end of the seat frame 2, the swing amplitude of the seat frame 2 and the user will become larger. By setting the first elastic member 51 and the second elastic member 52, the swing amplitude of the seat frame 2 is more uniform and the swing is smoother; and the overall structure is relatively simple.

[0052] The first elastic member 51 and the second elastic member 52 have the same structure, that is, the second elastic member 52 is also composed of a tension spring 511 and a belt 512 .

[0053] See also Figure 4 The Xiaoyao driving mechanism 4 further includes a rotating installation group 42, which is installed on the output end of the Xiaoyao driving motor 41 and rotates synchronously with the output end of the Xiaoyao driving motor 41. One end of the first elastic member 51 and one end of the second elastic member 52 are both connected to the rotating installation group 42. By providing the rotating installation group 42, the first elastic member 51 and the second elastic member 52 can be conveniently connected to ensure the stability of the structure.

[0054] Specifically, see Figure 4, the rotating installation group 42 includes a rotating plate 421, a shaft 422 and a mounting sleeve 423. The rotating plate 421 is a circular plate-shaped structure, which is installed on the output end of the Xiaoyao driving motor 41. The shaft 422 is arranged on the rotating plate 421, protruding outward relative to the rotating plate 421 and perpendicular to the rotating plate 421; more preferably, the rotating plate 421 and the shaft 422 are an integrally formed structure. The mounting sleeve 423 is sleeved on the shaft 422, and one end of the first elastic member 51 and one end of the second elastic member 52 are both connected to the mounting sleeve 423. The mounting sleeve 423 is mainly composed of three parts, and the middle cylinder is used to be sleeved on the shaft 422; positions for the tension spring 511 to be hooked are provided on both sides of the cylinder. The structure of the rotating installation group 42 is arranged in this way, and the first elastic member 51 and the second elastic member 52 can be conveniently connected to the output end of the Xiaoyao driving motor 41.

[0055] Embodiment 2

[0056] See also Figures 5 to 7 , the difference between this embodiment and the first embodiment lies in the structure of the Xiaoyao drive mechanism 4. In this embodiment, the Xiaoyao drive mechanism 4 includes a Xiaoyao drive motor 41, a turntable 43 and a pressure rod 44. The Xiaoyao drive motor 41 is installed on the base 1, and the turntable 43 is installed on the output end of the Xiaoyao drive motor 41; the turntable 43 is a circular disk, which has a hole at the center of the circle and is sleeved on the output end of the Xiaoyao drive motor 41. When the output end of the Xiaoyao drive motor 41 rotates, the turntable 43 can be driven to rotate around its center. The pressure rod 44 is arranged on the turntable 43 and is not coaxial with the output end of the Xiaoyao drive motor 41; the pressure rod 44 and the turntable 43 are an integrally formed structure, the pressure rod 44 protrudes outward relative to the turntable 43 and is perpendicular to the turntable 43, and the pressure rod 44 is located near the edge of the turntable 43 and is not coaxial with the output end of the Xiaoyao drive motor 41; when the turntable 43 rotates, the pressure rod 44 can be driven to rotate around the output end of the Xiaoyao drive motor 41.

[0057] See also Figure 6The elastic traction group 5 includes a first elastic rope 53, one end of which is connected to the base 1 and the other end is connected to the seat frame 2, and the first elastic rope 53 is in a straight state. The pressure rod 44 intersects with the first elastic rope 53 on the horizontal projection plane, and more preferably, the pressure rod 44 and the first elastic rope 53 are perpendicular to each other on the horizontal projection plane; the turntable 43 is located on one side of the first elastic rope 53, but the pressure rod 44 extends above or below the first elastic rope 53. When the pressure rod 44 rotates around the output end of the Xiaoyao drive motor 41, the pressure rod 44 will come into contact with the first elastic rope 53. The output end of the Xiaoyao drive motor 41 rotates, which can drive the turntable 43 to rotate synchronously, and the pressure rod 44 on the turntable 43 also rotates around the output end of the Xiaoyao drive motor 41; the pressure rod 44 will contact the first elastic rope 53 when it rotates to a certain angle, and the pressure rod 44 continues to rotate, which will apply pressure to the first elastic rope 53; the first elastic rope 53 will undergo elastic deformation after receiving the pressure from the pressure rod 44. Since one end of the first elastic rope 53 is connected to the base 1, and the base 1 is relatively fixed, the first elastic rope 53 has a pulling force on the seat frame 2 when it undergoes elastic deformation, and can pull the seat frame 2 to swing. When the pressure rod 44 continues to rotate to a certain position, the pressure rod 44 will separate from the first elastic rope 53 and will not contact it. At this time, the pressure rod 44 has no pressure on the first elastic rope 53. The first elastic rope 53 will tend to return to its original position (rebound to a straight state) due to its own elastic force and the fact that its two ends are respectively fixed to the seat frame 2 and the base 1. At this time, the seat frame 2 is not subjected to the tension generated by the first elastic rope 53 when it is elastically deformed, so the seat frame 2 also tends to return to its initial state. This is repeated to achieve the reciprocating swing of the seat frame 2.

[0058] The combination of the Xiaoyao driving motor 41 and the first elastic rope 53 can realize the electric controlled rocking of the rocking chair. The structure is simple, and the elastic deformation of the first elastic rope 53 is utilized to make the rocking process smoother and less noisy.

[0059] As mentioned above, the elastic traction group 5 can also achieve the swing of the traction seat frame 2 when it is composed only of the first elastic rope 53. Figure 6, the elastic traction group 5 may also include a second elastic rope, that is, the elastic traction group 5 is composed of a first elastic rope 53 and a second elastic rope 54. The second elastic rope 54 and the first elastic rope 53 are of the same material and structure. The two ends of the first elastic rope 53 are respectively connected to the rear end of the base 1 and the front end of the seat frame 2, specifically, one end of the first elastic rope 53 is connected to the rear lower end position of the base 1, and the other end is connected to the front upper end position of the seat frame 2. The two ends of the second elastic rope 54 are respectively connected to the front end of the base 1 and the rear end of the seat frame 2 of the connecting cross bar 231, specifically, one end of the second elastic rope 54 is connected to the front lower end position of the base 1, and the other end is connected to the rear upper position of the seat frame 2. The first elastic rope 53 and the second elastic rope 54 are in an X-shaped cross shape when viewed from the side. The pressure rod 44 intersects with the first elastic cord 53 and the second elastic cord 54 on the horizontal plane, and in the initial state, the pressure rod 44 is located behind the intersection of the first elastic cord 53 and the second elastic cord 54, and the pressure rod 44 is located above the first elastic cord 53 and below the second elastic cord 54. When the pressure rod 44 rotates from top to bottom, the pressure rod 44 first contacts the first elastic cord 53 and applies pressure to the first elastic cord 53; then the pressure rod 44 continues to rotate a certain angle and then contacts the second elastic cord 54 and applies pressure to the second elastic cord 54. The pressure rod 44 applies pressure to the first elastic cord 53 and the second elastic cord 54 in turn to achieve the swinging of the seat frame 2. In this embodiment, by providing the first elastic cord 53 and the second elastic cord 54, the swinging amplitude of the seat frame 2 is more uniform and the swinging is smoother; and the overall structure is also relatively simple.

[0060] See also Figure 8 The base 1 includes a bottom frame, a front fixing rod 12 and a rear fixing rod 13. The bottom frame is placed on the ground as the bottom frame of the entire rocking chair. The front fixing rod 12 and the rear fixing rod 13 have the same structure, are parallel to each other, and are arranged on the bottom frame at a front-to-back interval. A front fixing rod 12 and a rear fixing rod 13 are arranged on the left side of the bottom frame for installing the rocking assembly 3 on the left side; a front fixing rod 12 and a rear fixing rod 13 are also arranged on the right side of the bottom frame for installing the rocking assembly 3 on the right side.

[0061] See also Figure 3 The swing assembly 3 includes a front swing rod 31, a rear swing rod 32 and a mounting plate 33. The front swing rod 31 and the rear swing rod 32 have the same structure. The upper end of the front swing rod 31 is hinged to the upper half of the front fixed rod 12 through a rotating shaft, and the upper end of the rear swing rod 32 is hinged to the upper half of the rear fixed rod 13 through a rotating shaft. The front end of the mounting plate 33 is hinged to the lower end of the front swing rod 31 through a rotating shaft, and the rear end of the mounting plate 33 is connected to the lower end of the rear swing rod 32 through a rotating shaft. The mounting plate 33 is used to install the seat frame 2. The mounting plate 33 can swing back and forth relative to the base 1 when the front swing rod 31 and the rear swing rod 32 swing back and forth synchronously, so as to realize the back and forth swing of the seat frame 2.

[0062] By providing the front fixed rod 12, the rear fixed rod 13, the front swing rod 31, the rear swing rod 32 and the mounting plate 33, the structure of each component is simplified, thereby making the structure of the swing assembly 3 simpler, thereby facilitating assembly and saving manufacturing costs; and the mounting plate 33 can also facilitate the installation of the base 1.

[0063] See also Figure 8 The base 1 also includes a front limit plate 14 and a rear limit plate 15, which are respectively used to limit the front swing rod 31 from continuing to swing upward and limit the rear swing rod 32 from continuing to swing backward. The front limit plate 14 and the rear limit plate 15 have the same structure, both of which are sheet-like structures. Among them, the front limit plate 14 is installed on one side of the front end of the front fixed rod 12 and extends to the front of the front swing rod 31; when the front swing rod 31 swings forward to a certain extent, the front limit plate 14 will resist the front swing rod 31 to restrict the front swing rod 31 from continuing to swing forward. The rear limit plate 15 is installed on one side of the rear end of the rear fixed rod 13 and extends to the rear of the rear swing rod 32; when the rear swing rod 32 swings backward to a certain extent, the rear limit plate 15 will resist the rear swing rod 32 to restrict the rear swing rod 32 from continuing to swing backward. By setting the front limit plate 14 and the rear limit plate 15, the swing range of the seat frame 2 can be limited to ensure the safety of the swing. In addition, the front limit plate 14 and the rear limit plate 15 are both independent sheet structures relative to the front fixed rod 12, the front swing rod 31, the rear fixed rod 13, and the rear swing rod 32, so the structure of all parts of the entire swing assembly 3 is relatively simple and the manufacturing cost is low.

[0064] See also Figure 3 , the upper and lower ends of the front swing rod 31 extend backward to form a bent piece, and the upper and lower ends of the front swing rod 31 are respectively hinged to the front fixed rod 12 and the mounting plate 33; when the front swing rod 31 swings forward, the front limit plate 14 can abut against the bend of the front swing rod 31 to limit the front swing rod 31 from continuing to swing forward. Similarly, the upper and lower ends of the rear swing rod 32 extend forward to form a bent piece, and the upper and lower ends of the rear swing rod 32 are respectively hinged to the rear fixed rod 13 and the mounting plate 33; when the front swing rod 31 and the rear swing rod 32 swing forward and backward, the rear limit plate 15 can abut against the bend of the rear swing rod 32 to limit the rear swing rod 32 from continuing to swing forward. The front swing rod 31 and the rear swing rod 32 are both set as bending parts, which can increase the swing range of the rocking chair while limiting the swing range; and the front limiting plate 14 and the rear limiting plate 15 are against the bending part of the bending plate, so that the force exerted on the front swing rod 31 and the rear swing rod 32 is easier to disperse, thereby ensuring the stability of the structure.

[0065] See also Figure 3, the front swing rod 31, the rear swing rod 32 and the mounting plate 33 are all located on the outside of the bottom frame. The mounting plates 33 of the two groups of swing components 3 are both used to install the seat frame 2. The front swing rod 31, the rear swing rod 32 and the mounting plate 33 of one group of swing components 3 are located on the left side of the bottom frame, and the front swing rod 31, the rear swing rod 32 and the mounting plate 33 of the other group of swing components 3 are located on the right side of the bottom frame. Therefore, after the seat frame 2 is installed on the mounting plate 33, the entire base frame is located inside the seat frame 2. Therefore, when the volume of the seat frame 2 is the same, the base frame of this embodiment has a smaller volume, occupies a smaller area, and has a lower manufacturing cost. In addition, the swing component 3 is hidden inside the seat frame 2, which can improve the safety of use, prevent the external environment from interfering with the swing component 3, and ensure the normal use of the front and rear swing functions.

[0066] See also Figure 8 The bottom frame includes a left bottom bar 111, a right bottom bar 112, a front connecting bar 113 and a rear connecting bar 114. The left bottom bar 111 and the right bottom bar 112 have the same structure, and the length direction is the front-to-back extension direction. The two are parallel to each other and are spaced apart from each other from left to right. The front connecting bar 113 and the rear connecting bar 114 have the same structure, and the length direction is the left-to-right extension direction. The two are parallel to each other and are spaced apart from each other from front to back. The two ends of the front connecting bar 113 are respectively connected and fixed to the left bottom bar 111 and the right bottom bar 112, and the front connecting bar 113 is perpendicular to the left bottom bar 111 and the right bottom bar 112. The two ends of the rear connecting bar 114 are respectively connected and fixed to the left bottom bar 111 and the right bottom bar 112, and the rear connecting bar 114 is perpendicular to the left bottom bar 111 and the right bottom bar 112. In other embodiments, please refer to Figure 3 The two ends of the front connecting rod 113 can be connected to the front fixed rods 12 on the left and right sides respectively, and the two ends of the rear connecting rod 114 can be connected to the rear fixed rods 13 on the left and right sides respectively. The lower ends of the front fixed rod 12 and the right fixed rod in the left swing assembly 3 are both connected and fixed to the left bottom rod 111, and the lower ends of the front fixed rod 12 and the right fixed rod in the right swing assembly 3 are both connected and fixed to the right bottom rod 112, such as being directly welded or detachably connected and fixed. The structure of the bottom frame is also relatively simple and has high stability.

[0067] See also Figure 8 The base 1 further includes a mounting frame 115, which is mounted on the bottom frame and is used to mount the Xiaoyao driving mechanism 4. Specifically, the bottom frame further includes a middle connecting rod 116, the two ends of which are respectively connected and fixed to the left bottom rod 111 and the right bottom rod 112, and the middle connecting rod 116 is perpendicular to the left bottom rod 111 and the right bottom rod 112, and the middle connecting rod 116 is located between the front connecting rod 113 and the rear connecting rod 114. The mounting frame 115 is specifically mounted on the middle connecting rod 116. Such a configuration can not only improve the structural strength of the bottom frame, but also facilitate the installation of the Xiaoyao driving mechanism 4.

[0068] The seat frame 2 includes a main frame 21, a linkage drive mechanism 22 and a linkage hinge mechanism 23. The main frame 21 is the main part of the seat frame 2, and its shape is a frame structure. In the finished electric rocking chair, the main frame 21 also serves as a seat frame for the user to sit on. The main frame 21 is made of metal material to ensure the stability of the seat frame 2 structure. The main frame 21 is detachably mounted on the mounting plate 33 of the rocking assembly 3. The linkage drive mechanism 22 is mounted on the main frame 21, and the linkage drive mechanism 22 is used to drive the linkage hinge mechanism 23 to extend or retract. The linkage hinge mechanism 23 can be movably mounted on the main frame 21 and connected to the output end of the linkage drive mechanism 22. The end of the linkage hinge mechanism 23 near the front of the main frame 21 is used to install the leg support bracket (not indicated in the figure), and the end near the rear of the main frame 21 is used to install the backrest bracket (not indicated in the figure); the leg support bracket serves as the main support of the leg support, and supports the user's legs when in use, and the backrest bracket serves as the main support of the backrest, and supports the user's upper body when in use. The linkage drive mechanism 22 can drive the linkage hinge mechanism 23 to extend or contract. When the linkage drive mechanism 22 drives the linkage hinge mechanism 23 to extend, the linkage hinge mechanism 23 can drive the leg support bracket to lift, and at the same time increase the angle between the backrest bracket and the main frame 21, so that the leg support bracket can support the user's legs, and the backrest bracket can support the user lying down. By setting the linkage drive mechanism 22 or setting the linkage hinge mechanism 23, the effect of a "zero gravity" sofa can be achieved.

[0069] The existing functional sofas and chairs have complex structures, complicated production processes, large packaging volumes, small cabinet loading volumes, and high production and transportation costs. However, the present technical solution, by providing a frame-type main frame 21, directly uses the main frame 21 as a seat frame, eliminating the traditional wooden frame structure, so the overall structure is simpler, the production process is simpler, the manufacturing cost is lower, the product is more stable, and the weight of the entire product is lighter.

[0070] See also Fig.10The main frame 21 includes a left side frame 211, a right side frame 212, a first cross bar 213, a second cross bar 214 and a third cross bar 215. The left side frame 211 and the right side frame 212 have the same structure and are symmetrically arranged; the left side frame 211 and the right side frame 212 are both quadrilateral frame structures composed of four rods; the left side frame 211 and the right side frame 212 are opposite and spaced. Specifically, the lower end of the left side frame 211 is detachably connected to the mounting plate 33 of the swing assembly 3 on the left side, and the lower end of the right side frame 212 is detachably connected to the mounting plate 33 of the swing assembly 3 on the right side. One end of the first cross bar 213 is connected to the front corner of the upper end of the left side frame 211, and the other end of the first cross bar 213 is connected to the front corner of the upper end of the right side frame 212. One end of the second cross bar 214 is connected to the rear corner of the upper end of the left side frame 211, and the other end of the second cross bar 214 is connected to the rear corner of the upper end of the right side frame 212. The first cross bar 213 and the second cross bar 214 are arranged at intervals and parallel to each other. The leg support bracket is close to the front of the left frame 211 and the right frame 212, and the backrest bracket is close to the rear of the left frame 211 and the right frame 212. The two ends of the third cross bar 215 are respectively connected to the left frame 211 and the right frame 212 and are located below the second cross bar 214. The linkage drive mechanism 22 is installed on the third cross bar 215, and the linkage hinge mechanism 23 is located between the left frame 211 and the right frame 212.

[0071] The structure of the main frame 21 is set in this way, which can simplify the overall structure of the chair frame and improve the structural stability. The space utilization rate inside the main frame 21 is high, which reduces the packaging volume of the product, increases the loading volume, and thus reduces the transportation cost.

[0072] See also Figure 10 to Figure 11, the main frame 21 is a detachable structure. Specifically, the left side frame 211 and the right side frame 212 are an integrated frame structure, one end of the first cross bar 213 is detachably connected to the upper front corner of the left side frame 211, and the other end of the first cross bar 213 is detachably connected to the upper front corner of the right side frame 212. One end of the second cross bar 214 is detachably connected to the upper rear corner of the left side frame 211, and the other end of the second cross bar 214 is detachably connected to the upper rear corner of the right side frame 212. The two ends of the third cross bar 215 are detachably connected to the left side frame 211 and the right side frame 212, respectively. That is, the rods connecting the left side frame 211 and the right side frame 212 are all detachably connected to the left side frame 211 and the right side frame 212. Specifically, connecting pieces can be welded at both ends of the first crossbar 213, the second crossbar 214 and the third crossbar 215, holes can be opened on the connecting pieces, and holes can be opened at corresponding positions of the left frame 211 and the right frame 212, and then the first crossbar 213, the second crossbar 214 and the third crossbar 215 can be connected to the left frame 211 and the right frame 212 by connecting members (such as screws 222, bolts, etc.). By setting the main frame 21 in a detachable manner, unified production can be facilitated, and the main frame 21 is smaller in size before assembly, more convenient for transportation, larger in loading volume, and lower in transportation cost.

[0073] Of course, in other embodiments, the structures of the connection between the first cross bar 213, the second cross bar 214 and the third cross bar 215 and the left side frame 211 and the right side frame 212 can be other forms. For example, by using a clamping method, the two ends of the first cross bar 213, the second cross bar 214 and the third cross bar 215 are directly clamped on the left side frame 211 and the right side frame 212; or by using a threaded connection method, the two ends of the first cross bar 213, the second cross bar 214 and the third cross bar 215 are provided with threads, which can be directly screwed into the threaded holes on the left side frame 211 and the right side frame 212. The technical solution does not limit the detachable connection method of the main frame 21, as long as the detachable connection between the first cross bar 213, the second cross bar 214 and the third cross bar 215 and the left side frame 211 and the right side frame 212 can be achieved.

[0074] See also Fig.12Further, the linkage hinge mechanism 23 includes a connecting cross bar 231, a left hinge assembly 232 and a right hinge assembly 233. The left hinge assembly 232 and the right hinge assembly 233 have the same structure and are symmetrically arranged, wherein the left hinge assembly 232 can be movably mounted on the left side frame 211, and the right hinge assembly 233 can be movably mounted on the right side frame 212. The connecting cross bar 231 is connected to the output end of the linkage drive mechanism 22, and the two ends are respectively connected to the left hinge assembly 232 and the right hinge assembly 233. The linkage drive mechanism 22 can push the connecting cross bar 231 forward or pull it backward. When the linkage drive mechanism 22 pushes the connecting cross bar 231 forward, the left hinge assembly 232 and the right hinge assembly 233 extend synchronously, thereby lifting the leg support bracket and increasing the angle between the backrest bracket and the main frame 21. When the linkage drive mechanism 22 pulls the connecting cross bar 231 backward, the left hinge assembly 232 and the right hinge assembly 233 contract synchronously, thereby retracting the leg support bracket and reducing the angle between the backrest bracket and the main frame 21. The linkage hinge mechanism 23 makes the adjustment of the leg support bracket and the backrest bracket more stable and smooth by setting the left hinge assembly 232 and the right hinge assembly 233. The synchronous adjustment of the left hinge assembly 232 and the right hinge assembly 233 can be achieved by connecting the cross bar 231, and only one linkage drive mechanism 22 needs to be set, which not only reduces costs but also improves synchronization. The connecting cross bar 231 can also improve the structural stability of the left hinge assembly 232 and the right hinge assembly 233, ensuring the stability of the rocking chair adjustment.

[0075] As described above, the left hinge assembly 232 and the right hinge assembly 233 have the same structure; therefore, only the specific structure of the left hinge assembly 232 is described in detail here to avoid repeated description.

[0076] See also Fig.13Specifically, the left hinge assembly 232 includes a first link 2321, a second link 2322, a third link 2323, a fourth link 2324, a long rod 2325 and a left connecting plate 2326. One end of the first link 2321 and one end of the second link 2322 are both rotatably connected to the left side frame 211. The other end of the first link 2321 is rotatably connected to one end of the third link 2323. One end of the second link 2322 is rotatably connected to one end of the fourth link 2324. The third link 2323 is rotatably connected to the fourth link 2324. The other end of the third link 2323 and the other end of the fourth link 2324 are connected to the leg support bracket. One end of the long rod 2325 is rotatably connected to the second link 2322, and the other end of the long rod 2325 is rotatably connected to the left connecting plate 2326. The left connecting plate 2326 is rotatably connected to the left side frame 211, and the left connecting plate 2326 is also connected to the backrest bracket. One end of the connecting cross bar 231 is connected to the second connecting rod 2322, and the other end of the connecting cross bar 231 is connected to the second connecting rod 2322 in the right hinge assembly 233. The structure of the left hinge assembly 232 provided in this embodiment can simultaneously realize the lifting or retracting of the leg support bracket and the angle adjustment of the backrest bracket through a simple structure.

[0077] See also Fig.13 , the left hinge assembly 232 also includes a fixing plate 2327. One end of the first link 2321 and one end of the second link 2322 are both rotatably connected to the fixing plate 2327, and the fixing plate 2327 is fixedly connected to the fixing plate 211; that is, one end of the first link 2321 and the second link 2322 are rotatably connected to the fixing plate 2327, so that the first link 2321 and the second link 2322 are connected to the fixing plate 211. By providing the fixing plate 2327, the left hinge assembly 232 can be easily assembled, and the structure of the left hinge assembly 232 is more complete; and the left hinge assembly 232 can be more conveniently installed on the fixing plate 211. On the other hand, the fixing plate 2327 connects the first link 2321 and the second link 2322, so that the extension and retraction actions of the left hinge assembly 232 are smoother.

[0078] See also Fig.12The linkage drive mechanism 22 includes a linkage drive motor 221, a screw rod 222 and a movable housing 223. The output end of the linkage drive motor 221 is connected to one end of the screw rod 222 and is used to drive the screw rod 222 to rotate. The movable housing 223 is sleeved on the screw rod 222 and is threadedly connected to the screw rod 222. The linkage drive motor 221 is installed on the third cross bar 215. One end of the movable housing 223 away from the linkage drive motor 221 is connected to the linkage hinge mechanism 23, specifically to the middle position of the connecting cross bar 231. The linkage drive motor 221 rotates, which can drive the screw rod 222 to rotate around the central axis. When the screw rod 222 rotates, it can drive the movable housing 223 to move relative to the screw rod 222 along the vertical direction of the screw rod 222. The linkage drive motor 221 can be controlled to achieve forward and reverse rotation, so the screw 222 can also rotate forward or reverse. The movable housing 223 can move in two directions under the action of the screw 222, thereby driving the linkage hinge mechanism 23 to extend or contract.
