Description

Technical Field

[0001] This utility model relates to the field of smart furniture technology, and in particular to an electric rocking chair. Background Technology

[0002] Rocking chairs, or chairs with similar structures and functions, are common pieces of furniture often seen in living rooms, family rooms, studies, home offices, and corporate offices, meeting rooms, and cinemas. These chairs are typically found in various homes, offices, or rooms because users often sit in them while watching television or movies, reading, etc. In short, one function of a rocking chair is to provide a relaxing environment for its user. More specifically, these rocking chairs can be positioned in various ways, such as a seated position, a television position, and a fully reclined position. Along this line of thought, conventional rocking chairs often include or incorporate a rocking mechanism to provide another mode of relaxation.

[0003] However, the disadvantage of such conventional rocking mechanisms, including those found in rocking chairs, is that they only allow the user of the chair or the user to utilize the rocking function when the chair or the chair is in a seated position, or when the chair is configured to be in a seated position.

[0004] However, the process of opening and closing the rocking chair is quite complicated, and the connection structure is complex. Furthermore, the transmission method during the lifting process is complex, resulting in a small tilt angle of the rocking chair's seat frame. In addition, the existing rocking chairs do not provide sufficient support and limit for their seat frames. Utility Model Content

[0046] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0047] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "setting," and "connection" should be interpreted broadly. For example, the term "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0048] It should be noted in advance that since some of the structures in this application are improvements on our earlier application (US patent application, electric rocking chair, application number: 18 / 132401, DAS code: 5797), its working state is similar to that of the earlier application. Therefore, in the following discussion of this application, only the improved parts will be described in detail, while the parts whose overall working state is no different from that of the earlier application will not be described in detail.

[0049] Reference Appendix Figure 1-3This invention discloses an improved electric rocking chair constructed according to the principles and teachings of the present invention, and is generally designated by reference numeral 100. More specifically, it should be understood that the improved electric rocking chair 100 includes a base assembly 102, a rocking assembly 104, a backrest reclining assembly 106, a seat assembly 108, a footrest assembly 110, a first linear actuator 112, a second linear actuator 114, and a linkage assembly 116 that operatively interconnects the various components and linear actuators, such that the improved electric rocking chair 100 can practically reach a variety of predetermined positions or modes, such as a seated position or mode, a television position or mode, and a fully reclined position or mode.

[0050] See Figure 3 The base assembly 102 includes a pair of laterally spaced, longitudinally extending chair legs 118, which are arranged parallel to each other and are fixedly connected together by longitudinally spaced, laterally extending crossbeams 120 below the first pair of chair legs 118. In addition, the opposite ends of the two longitudinally spaced, laterally extending crossbeams 120 are fixedly connected together by a pair of longitudinally extending mounting plates 122.

[0051] See Figure 2 and Figure 4-5 The seat assembly 108 also includes a pair of opposing seat supports 142, which are connected together at their lower front ends via a transversely oriented crossbeam 144, and the seat supports 142 are fixedly connected to the outer surface of the mounting bracket 128 of the rocking assembly 104.

[0052] The rocking assembly 104 includes two pairs of compression springs 124, each pair of springs 124 being disposed above each mounting plate 122, and a pair of opposing rocker blocks 126 being disposed above each of the pair of laterally spaced longitudinally extending chair legs 118. Additionally, a mounting bracket 128 is fixedly attached to the upper surface of any of the rocker blocks 126, and longitudinally spaced laterally extending crossbeams 130 above the second pair of chair legs 118 are fixedly connected to the opposing mounting brackets 128. Furthermore, a pair of longitudinally extending fixing plates 132 connect the ends of the longitudinally spaced laterally extending crossbeams 130 above the second pair of chair legs 118 and are also disposed above the pairs of compression springs 124.

[0053] See Figure 1 and Figure 2 as well as Figure 4-8The reclining backrest assembly 106 includes a mounting bracket 136, wherein the mounting bracket 136 is a pair of laterally spaced T-shaped backrest mounting brackets, and each of the T-shaped backrest mounting brackets is fixedly connected to the upper end of a pair of laterally spaced left and right connecting plates 138. The lower ends of the pair of laterally spaced left and right connecting plates 138 are connected together by a first laterally oriented crossbeam 140.

[0054] Additionally, the third laterally oriented crossbeam 154 is fixedly connected to the footrest swing link 206 opposite to the footrest assembly 110, and the first linear actuator 112, installed in the linear actuator mounting base 134, includes a motor 156 and an extendable telescopic tube or telescopic rod 158, wherein the distal end of the telescopic tube or telescopic rod 158 is pivotally mounted in a U-shaped mounting base 160, which is fixedly mounted on the third laterally oriented crossbeam 154, so that the crossbeam 154 can be directly pushed by the telescopic tube or telescopic rod 158 to open and retract the footrest assembly 110.

[0055] The motor 156 of the second linear actuator 114 is pivotally mounted on the second transversely oriented crossbeam 144, while the telescopic tube or telescopic rod 159 is pivotally mounted on the first transversely oriented crossbeam 140 via a U-shaped hook joint 161.

[0056] Further description of seat assembly 108, from Figure 2 , Figure 5 and Figure 9 As can be seen, a pair of seat links 162 are connected to each seat bracket 142 by an integrally inwardly extending connecting bracket 164. The connecting bracket 164 is adapted to be fastened by fasteners that pass through holes 165 and also pass through connecting brackets 166 that are provided on the seat brackets 142 and have corresponding holes 168 and integrally extend inwardly.

[0057] See Figure 1 , Figure 2 and Figure 4-8 The backrest reclining assembly 106, the seat assembly 108, and the linkage assembly 116 will now be described.

[0058] Specifically, the seat assembly 108 includes a pair of opposing seat plates 170 pivotally connected to a pair of T-shaped backrest mounting brackets 136 via pivot pins 172. Front and rear L-shaped mounting brackets 174 are mounted at the bottom of the electric rocking chair's frame to serve as mounting platforms for the seat of the rocking chair 100. Additionally, a Z-shaped stop 176 is also mounted on the frame to support and limit the seat frame, and this Z-shaped stop 176 has limiting rollers 178. When the backrest is at its lowest position, the limiting rollers are adapted to support the upper surfaces of a pair of laterally spaced, longitudinally extending chair legs 118 to prevent the rocking chair 100 from rocking in a predetermined position or mode.

[0059] More specifically, the connecting rod 180 is V-shaped or L-shaped and pivotally connected at its rear end to the inner surface of the seat plate 170 via a first connecting pivot 182. Furthermore, from... Figure 5 As can be best seen in the image, the rear end of the seat link 162 is pivotally connected at pivot 184 to the apex of the V-shaped or L-shaped connecting rod 180, while the front end of the seat link 162 is pivotally connected at the second connecting pivot 186 to the front end of the seat plate 170 via a pivot connector 187. This allows for... Figure 5 and Figure 9 The best view is in the middle.

[0060] See Figure 6-8 The linkage assembly for actuating the footrest assembly 110, which is part of the overall linkage assembly 116, will now be described. More specifically, the linkage assembly of the footrest assembly 110 includes a pair of footrest drive links 196, the first end of which is pivotally connected at a fifth connecting pivot 198 to a connecting rod 180, and the second end of which is pivotally connected at a sixth connecting pivot 202 to a pair of opposing, lower footrest swing links 200. The first end of the lower footrest swing link 200 is pivotally connected to the seat plate 170 at the seventh connecting pivot 204, while the first ends of the pair of upper footrest swing links 206 are pivotally connected to the seat plate 170 at the eighth connecting pivot 208. When the telescopic tube or telescopic rod 158 of the first linear actuator 112 is extended, it pushes the upper footrest swing link 206 to rotate and open around the eighth connecting pivot 208, thereby opening the upper footrest extension link 210 and the lower footrest swing link 200. The lower footrest swing link 200 rotates and opens around the seventh connecting pivot 204, causing the footrest drive link 196 to move forward, thereby causing the connecting rod 180 to rotate clockwise at the pivot 184, so that the rear end of the seat plate 170, which is hinged to the rear end of the connecting rod 180, sinks down, thereby making the seat frame tilt angle greater.

[0061] Furthermore, it can be seen that the opposite second end of the lower footrest swing link 200 is pivotally connected at the ninth connecting pivot 212 to a pair of opposite upper footrest extension links 210. It can also be seen that the second end of the upper footrest swing link 206 is pivotally connected to the first end of a pair of lower footrest extension links 214, and pivotally connected at the tenth connecting pivot 216 to the middle portion of the upper footrest extension link 210.

[0062] Furthermore, the middle portion of the lower footrest extension link 214 is pivotally connected at the eleventh connecting pivot 220 to the first end of a pair of first footrest support links 218, while the opposing second ends of the pair of first footrest support links 218 are pivotally connected at the twelfth connecting pivot 224 to the first ends of a pair of second footrest support links 222. It can also be seen that the second end of the lower footrest extension link 214 is pivotally connected at the thirteenth connecting pivot 228 to one end of a pair of opposing front footrest support brackets 232, while the opposing second ends of the second footrest support links 222 are pivotally connected at the fourteenth connecting pivot 234 to a pair of opposing front footrest support brackets 232. It should also be noted that the front footrest support bracket 232 is slidably connected to the rear footrest support bracket 226 via a pin 236 that can slide within a groove 230.
