Description

Technical Field

[0001] This utility model relates to the field of reclining chair technology, and in particular to a reclining chair. Background Technology

[0002] With the improvement of living standards, recliners have gradually become an essential leisure item in the home, enhancing the quality of life and adding enjoyment. However, since recliners only accommodate one or two people, they cannot replace sofas in home design. Therefore, to minimize the space occupied by recliners, foldable designs have become the mainstream approach.

[0003] In the prior art, a recliner includes a frame, a backrest, and a footrest. Both the backrest and footrest are connected to the frame and can rotate relative to it, allowing the recliner to be folded. However, existing recliners can only be folded in the height direction, while the width of the folded recliner remains unchanged. This results in the recliner still occupying a considerable amount of space after folding, necessitating further improvement. Utility Model Content

[0004] The purpose of this invention is to provide a recliner that can be folded and has a small volume after folding, requiring less space.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A recliner, including a recliner frame having an unfolded state and a folded state, the recliner frame comprising:

[0007] The side support is provided in two sets, and each set of the side support includes a front support leg and a rear support leg that are rotatably connected.

[0008] The support frame includes an upper support and a lower support that are movably connected, wherein the upper support is rotatably mounted on the side support;

[0009] In the unfolded state, the support frame is supported between the two sets of side supports, and the lower support extends outward from the plane where the upper support is located and together with the upper support forms a support space;

[0010] In the folded state, the lower support is folded together to the upper support, the upper support moves toward the rear support leg, and the front support leg moves toward the rear support leg.

[0011] In one embodiment, the side support further includes a first linkage assembly disposed between the front support leg and the rear support leg.

[0012] The first linkage assembly includes a first linkage component and a second linkage component that are rotatably connected;

[0013] The first linkage is rotatably connected to the front support leg, and the second linkage is rotatably connected to the rear support leg;

[0014] In the unfolded state, the first linkage component is supported between the front support leg and the rear support leg. In the folded state, the position where the first linkage component and the second linkage component are rotatably connected moves downward so that the first linkage component is folded between the front support leg and the rear support leg.

[0015] In one embodiment, the side supports are a first side support and a second side support. The recliner also has a second linkage assembly disposed between the front leg and the rear leg. The second linkage assembly includes a first rod and a second rod that are rotatably connected. One end of the first rod is movably connected to the first linkage assembly of the first side support, and the other end of the first rod is movably connected to the second side support. One end of the second rod is movably connected to the first linkage assembly of the second side support, and the other end of the second rod is movably connected to the first side support. This allows the first side support and the second side support to move closer together when the first linkage assembly moves and folds.

[0016] In one embodiment, the recliner frame further includes two first adapters, which are rotatably connected to two sets of first linkage components in a one-to-one correspondence, and the second linkage components are rotatably connected to the two first adapters; the axis of rotation of the second linkage component relative to the first adapters intersects with the axis of rotation of the first adapters relative to the first linkage components.

[0017] The recliner frame also includes two second adapters, which are rotatably connected to the two sets of side supports in a one-to-one correspondence. The second linkage component is rotatably connected to the two second adapters. The axis of rotation of the second linkage component relative to the second adapters intersects with the axis of rotation of the second adapters relative to the side supports.

[0018] In one embodiment, the upper support includes a first support rod with one end rotatably connected to one of the side supports and a second support rod with one end rotatably connected to the other side support. A straight support structure is provided between the first support rod and the second support rod. The straight support structure includes two first horizontal support rods with their ends rotatably connected to each other. The other ends of the two first horizontal support rods are rotatably connected to the other ends of the first support rod and the other ends of the second support rod, respectively. The lower support is rotatably connected to the first support rod and the second support rod.

[0019] When the recliner frame is in the folded state, the straight support structure moves to bring the first support rod and the second support rod closer together.

[0020] In one embodiment, when the recliner frame is folded, the first cross brace rotatably connected to the first support rod rotates in the direction toward the first support rod, and the first cross brace rotatably connected to the second support rod rotates in the direction toward the second support rod.

[0021] In one embodiment, the lower support includes a third support rod with one end rotatably connected to the first support rod and a fourth support rod with one end rotatably connected to the second support rod; a second straight support structure is provided between the third support rod and the fourth support rod, the second straight support structure includes two second horizontal support rods with their ends rotatably connected to each other, and the other ends of the two second horizontal support rods are respectively rotatably connected to the other end of the third support rod and the other end of the fourth support rod;

[0022] When the recliner frame is in the folded state, the second straight support structure moves to bring the third support rod and the fourth support rod closer together.

[0023] In one embodiment, when the recliner frame is folded, the lower support folds backward and moves toward the upper support, while the upper support and the lower support fold downward and move toward the front leg or the rear leg, and retract with the front leg and the rear leg in the left-right direction.

[0024] In one embodiment, the upper support has a first rotating shaft, and the side support has a second rotating shaft, wherein the first rotating shaft and the second rotating shaft are coaxially rotatably connected.

[0025] In one embodiment, the recliner frame further includes a locking structure disposed on one of the upper support and the side support, and detachably connected to the other to restrict rotation of the upper support relative to the side support.

[0026] The beneficial effects of this utility model are:

[0027] The recliner provided by this utility model includes a front support leg and a rear support leg for each set of side supports. The upper support of the support frame is rotatably mounted on the side supports. In the unfolded state, the support frame is supported between the two sets of side supports. The upper and lower supports of the support frame can form a support space for carrying. In the folded state, the lower support is folded towards the upper support, and the upper and lower supports are folded towards the rear support leg. The front support leg is folded towards the rear support leg, so that the upper support, lower support, and front support leg are all folded towards the rear support leg. This realizes the folding and reclining of the recliner frame in the front-to-back direction. The dimensions of the recliner in the length direction are all small, the overall volume is greatly reduced, the space occupied is small, and it is also convenient for the recliner to be stored and carried.

[0045] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0046] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two sets of components or the interaction between two sets of components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0047] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0048] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0049] This embodiment provides a recliner that can be folded and has a small volume when folded, requiring less space.

[0050] like Figures 1 to 15 As shown, the recliner includes a recliner frame (not shown) with an unfolded state and a folded state. When unfolded, the recliner frame has a larger volume, allowing the user to sit or lie down; when folded, the recliner frame has a smaller volume, facilitating storage or transportation. In this embodiment, Figure 6 and Figure 11 This is a diagram showing the recliner frame in its unfolded state. Figure 10 and Figure 15 This is a diagram showing the recliner frame in a folded state.

[0051] like Figure 1 As shown, the recliner frame includes two sets of side supports 1 disposed on the left and right sides. Exemplarily, each side support 1 includes a front support leg 11 and a rear support leg 12 rotatably connected. The front support leg 11 and the rear support leg 12 serve as supports for the entire recliner frame, allowing the recliner frame to be stably supported on a flat surface when in the unfolded state. For example, the front support leg 11 and the rear support leg 12 are rotatably connected, allowing the front support leg 11 to move closer to the rear support leg 12. Optionally, the top end of the front support leg 11 is rotatably connected to the top end of the rear support leg 12, and the bottom end of the front support leg 11 and the bottom end of the rear support leg 12 are positioned opposite each other in the front-rear direction.

[0052] In some alternative embodiments, such as Figure 1 As shown, the recliner frame also includes a support frame 4, which is movably connected between the two sets of side supports 1 and is used to provide support for the user, making it convenient for the user to sit or lie down. When the recliner frame is folded, the support frame 4 folds and retracts relative to the front support leg 11 or the rear support leg 12, and moves closer to the front support leg 11 or the rear support leg 12, so that the support frame 4 can also be folded, further reducing the overall volume of the recliner frame.

[0053] For example, such as Figure 4 and Figure 5 As shown, the support frame 4 includes an upper support 41 and a lower support 42 that are movably connected. The upper support 41 is rotatably mounted on the side support 1.

[0054] In this embodiment, in the unfolded state, the support frame 4 is supported between two sets of side supports 1. The lower support 42 extends outward from the plane of the upper support 41 and together with the upper support 41 forms a support space 10. The support space 10 is used to accommodate the support fabric or other structures for supporting the user. In the folded state, the lower support 42 folds towards the upper support 41, the upper support 41 folds towards the rear support leg 12, and the front support leg 11 folds towards the rear support leg 12 to achieve the folding of the recliner frame. It should be noted that when the lower support 42 folds towards the upper support 41, it can be folded by rotation or by sliding; this embodiment does not limit this. It should also be noted that the lower support 42 extends outward from the plane of the upper support 41, which can be understood as the plane of the upper support 41 being coplanar with the plane of the lower support 42.

[0055] In this embodiment, when the recliner frame is folded, the lower support 42 folds and retracts relative to the upper support 41, so that it can be folded down by... Figure 6 The state transition shown is to Figure 7 The state shown represents the pre-folding of the lower support 42. By folding the lower support 42 relative to the upper support 41, the longitudinal dimension of the support frame 4 can be reduced, resulting in a smaller overall size for the folded support frame 4. The upper support 41 is rotatably connected to the side support 1, and both the upper support 41 and the front support leg 11 can move closer to the rear support leg 12, further reducing the overall size of the folded recliner frame and allowing for a smaller overall size. In some optional embodiments, the lower support 42 folds backward and moves closer to the upper support 41, such as... Figure 6 As shown, the lower support 42 rotates along the first rotation direction r0 around the tenth axis c1, and rotates until it is close to the upper support 41. Figure 7 As shown, the upper support 41 and the lower support 42 rotate around the fourth axis a4 along the second rotation direction r1 and move closer to the rear support leg 12.

[0056] In this embodiment, the lower support 42 can be a footrest for supporting the user's feet. In this embodiment, the upper support 41 can be a backrest for the user to lean against.

[0057] In one possible implementation, the side support 1 further includes a first linkage component 2 disposed between the front support leg 11 and the rear support leg 12. By providing the first linkage component 2, the connection between the front support leg 11 and the rear support leg 12 can be realized, and the relative position of the front support leg 11 and the rear support leg 12 in the deployed state can also be limited.

[0058] Optionally, such as Figure 1 or Figure 2As shown, the first linkage assembly 2 includes a first linkage member 21 and a second linkage member 22 that are rotatably connected. Exemplarily, both the first linkage member 21 and the second linkage member 22 are rod-shaped. In some optional embodiments, both the first linkage member 21 and the second linkage member 22 are hollow tubes.

[0059] The first linkage 21 is rotatably connected to the front support leg 11, and the second linkage 22 is rotatably connected to the rear support leg 12. Specifically, one end of the first linkage 21 is rotatably connected to one end of the second linkage 22, the other end of the first linkage 21 is rotatably connected to the front support leg 11, and the other end of the second linkage 22 is rotatably connected to the rear support leg 12. In the deployed state, as shown... Figure 1 As shown, the first linkage component 2 is supported between the front support leg 11 and the rear support leg 12; in the folded state, as... Figure 10 As shown, the position where the first linkage 21 and the second linkage 22 are rotatably connected is moved downward so that the first linkage 21 is folded between the front support leg 11 and the rear support leg 12.

[0060] For example, in this embodiment, the two side supports are a first side support and a second side support, respectively. Please refer to [link / reference]. Figure 1 The recliner frame also includes a second linkage component 3. The second linkage component 3 is disposed between the front support leg 11 and the rear support leg 12. The second linkage component 3 is movably connected to both the first side support and the second side support to achieve linkage with the first side support and the second side support.

[0061] For example, the first linkage component 2 and the second linkage component 3 are movably connected, so that the first linkage component 2 and the second linkage component 3 operate synchronously, that is, the second linkage component 3 moves at the same time as the first linkage component 2 moves. When the recliner frame changes from the unfolded state to the folded state, the first linkage component 2 can drive the front support leg 11 and the rear support leg 12 to move closer together, so as to realize the folding of each set of side supports 1 in the front-back direction. When the first linkage component 2 drives the front support leg 11 and the rear support leg 12 to move closer together, it can also drive the second linkage component 3 to move so that the two sets of side supports 1 move closer together, so as to realize the folding of the recliner frame in the left-right direction. This achieves bidirectional folding of the recliner frame, so that the dimensions of the folded recliner frame in both the front-back direction and the left-right direction are reduced, thereby significantly reducing the overall volume of the recliner.

[0062] The recliner provided in this embodiment includes a front leg 11 and a rear leg 12 in each set of side supports 1. A first linkage component 2 is movably connected between the front leg 11 and the rear leg 12 of the same set of side supports 1. The movement of the front leg 11 relative to the rear leg 12 can drive the first linkage component 2 to move, and the movement of the first linkage component 2 can drive the front leg 11 to move relative to the rear leg 12. A second linkage component 3 is movably connected to both sets of first linkage components 2 and both sets of side supports 1. The first linkage components 2 and the second linkage component 3 operate synchronously, causing the recliner frame to fold from an unfolded state. When the folded state is switched, the first linkage component 2 drives the front support leg 11 and the rear support leg 12 to move closer to each other, and drives the second linkage component 3 to move so that the two sets of side supports 1 move closer to each other, realizing the folding and retraction of the recliner frame in the left-right and front-back directions. The linkage between the first linkage component 2 and the second linkage component 3 allows the folding in the left-right direction and the folding in the front-back direction to be carried out simultaneously, realizing bidirectional folding and retraction, improving the folding and retraction efficiency. The dimensions of the recliner in the length and width directions are relatively small, and the overall volume is greatly reduced, making it easy to store and carry the recliner and providing high flexibility.

[0063] By setting the first linkage component 21 and the second linkage component 22, the structure of the first linkage component 2 is relatively simple, and it can realize the mutual approach and mutual distance between the front support leg 11 and the rear support leg 12, with rich functions.

[0064] For example, the front support leg 11 and the rear support leg 12 form an inverted V-shape. Specifically, one end of the front support leg 11 is rotatably connected to one end of the rear support leg 12, the first linkage 21 is rotatably connected to the middle of the front support leg 11, and the second linkage 22 is rotatably connected to the middle of the rear support leg 12. It should be noted that in this embodiment, the middle of the front support leg 11 specifically refers to the portion located between the two ends of the front support leg 11, which can be the central region along the length of the front support leg 11, but is not specifically defined or limited to the central region along the length of the front support leg 11. Similarly, the middle of the rear support leg 12 specifically refers to the portion located between the two ends of the rear support leg 12, which can be the central region along the length of the rear support leg 12, but is not specifically defined or limited to the central region along the length of the rear support leg 12.

[0065] When the recliner frame is folded (i.e., the recliner frame changes from an unfolded state to a folded state), the ends of the first linkage 21 and the second linkage 22 that are rotatably connected move in a direction away from the rotatable connection position between the front support leg 11 and the rear support leg 12. For example... Figure 8 As shown, the ends of the first linkage 21 and the second linkage 22 that are rotatably connected move along the x-direction, so that the first linkage 21 and the second linkage 22 can have sufficient accommodating space, avoiding interference with the connection positions of the front support leg 11 and the rear support leg 12, and improving the reliability of the operation.

[0066] Optionally, such as Figure 3As shown, the second linkage assembly 3 includes a first rod 31 and a second rod 32 rotatably connected. One end of the first rod 31 is movably connected to the first linkage assembly 2 of the first side bracket, and the other end of the first rod 31 is movably connected to the second side bracket. One end of the second rod 32 is movably connected to the first linkage assembly 2 of the second side bracket, and the other end of the second rod 32 is movably connected to the first side bracket. Thus, when the first linkage assembly moves and folds, it can drive the first and second side brackets to move closer together, achieving left and right folding of the recliner frame, thus occupying less space. The second linkage assembly 3 in this embodiment has a simple structure and high reliability and stability.

[0067] For example, the center of the first member 31 is rotatably connected to the center of the second member 32, that is, the first member 31 and the second member 32 are connected to form a cross brace structure 30. The cross brace structure 30 can provide support when unfolded and occupy less space when folded. Furthermore, when the first member 31 and the second member 32 of the cross brace structure 30 rotate relative to each other, they can drive the first side support and the second side support to move closer to each other or away from each other in the left-right direction. When the first side support and the second side support move closer to each other or away from each other in the left-right direction, they will also drive the first member 31 and the second member 32 to rotate relative to each other, thus unfolding or folding.

[0068] In one possible implementation, such as Figure 1 As shown, the recliner frame also includes two first adapter pieces 5. Each of the two first adapter pieces 5 is rotatably connected to one of the two sets of first linkage components 2. A second linkage component 3 is rotatably connected to both first adapter pieces 5, such that one first adapter piece 5 is rotatably connected to one set of first linkage components 2, and the other first adapter piece 5 is rotatably connected to another set of first linkage components 2. The axis of rotation of the second linkage component 3 relative to the first adapter piece 5 intersects with the axis of rotation of the first adapter piece 5 relative to the first linkage component 2.

[0069] By setting the first adapter 5, the second linkage assembly 3 has two rotatable directions relative to the first linkage assembly 2, thus providing high flexibility. This allows the first link 31 and the second link 32 of the second linkage assembly 3 to rotate relative to each other, while also rotating relative to the first adapter 5. Similarly, when the first linkage 21 of the first linkage assembly 2 rotates relative to the second linkage 22, the first adapter 5 can rotate relative to both the first linkage 21 and the second linkage 22, eliminating the need for the first link 31 and the second link 32 to rotate in the same direction as either the first linkage 21 or the second linkage 22.

[0070] In some alternative embodiments, please continue to refer to Figure 1The recliner frame also includes two second adapters 6, which are rotatably connected to two sets of side supports 1 in a one-to-one correspondence. A second linkage assembly 3 is rotatably connected to the two second adapters 6, so that one second adapter 6 is rotatably connected to one set of side supports 1, and the other second adapter 6 is rotatably connected to another set of side supports 1. The axis of rotation of the second linkage assembly 3 relative to the second adapters 6 intersects with the axis of rotation of the second adapters 6 relative to the side supports 1.

[0071] By setting the second adapter 6, the second linkage assembly 3 has two rotatable directions relative to the side bracket 1, so as to have high flexibility. When the first rod 31 and the second rod 32 of the second linkage assembly 3 rotate relative to each other, they can rotate relative to the second adapter 6. When the front support leg 11 rotates relative to the rear support leg 12, the second adapter 6 can rotate relative to the front support leg 11 and the rear support leg 12, so that the first rod 31 and the second rod 32 do not need to rotate in the same direction as the front support leg 11 or the rear support leg 12.

[0072] For example, such as Figure 2 As shown, when the first linkage 21 rotates relative to the front support leg 11, it rotates about the first axis a1. When the first linkage 21 rotates relative to the second linkage 22, its axis of rotation is the second axis a2. When the second linkage 22 rotates relative to the rear support leg 12, it rotates about the third axis a3. When the front support leg 11 and the rear support leg 12 rotate relative to each other, their axis of rotation is the fourth axis a4. Figure 3 As shown, the axis of rotation of the first adapter 5 relative to the first linkage assembly 2 is the fifth axis b1, and the axis of rotation of the first rod 31 and the second rod 32 relative to the first adapter 5 is the sixth axis b2. The axis of rotation of the second adapter 6 relative to the side bracket 1 is the seventh axis b3, and the axis of rotation of the first rod 31 and the second rod 32 relative to the second adapter 6 is the eighth axis b4. The first rod 31 rotates around the ninth axis b5 when it rotates relative to the second rod 32. The first axis a1, second axis a2, third axis a3, and fourth axis a4 are parallel to each other. The second axis a2 is collinear with the fifth axis b1, and the fourth axis a4 is collinear with the seventh axis b3. The fifth axis b1 and the sixth axis b2 are perpendicular to each other. The seventh axis b3 and the eighth axis b4 are perpendicular to each other. The ninth axis b5, the eighth axis b4, and the sixth axis b2 are parallel to each other.

[0073] When the recliner frame is folded, as Figure 8 As shown, the first linkage 21 rotates about the first axis a1 along the fifth rotation direction r4, and the second linkage 22 rotates about the fourth axis a4 along the sixth rotation direction r5. Figure 8As shown, the ends of the first rod 31 and the second rod 32 connected to the first linkage assembly 2 move along the X direction, one side bracket 1 moves along the O direction, and the other side bracket 1 moves along the P direction, so that the two side brackets 1 gradually move closer to each other until they are folded into shape. Figure 10 and Figure 15 The structure shown.

[0074] Optionally, such as Figure 4 As shown, the upper support 41 includes a first support rod 411 with one end rotatably connected to a side support 1 and a second support rod 412 with one end rotatably connected to the other side support 1. A straight support structure 413 is provided between the first support rod 411 and the second support rod 412. The straight support structure 413 includes two first horizontal support rods 4131 with their ends rotatably connected to each other, and the other ends of the two first horizontal support rods 4131 are rotatably connected to the other ends of the first support rod 411 and the second support rod 412, respectively. When the recliner frame is folded, the straight support structure 413 moves to bring the first support rod 411 and the second support rod 412 closer together. By providing the straight support structure 413, the upper support 41 can be folded in the left and right directions. In this embodiment, the lower support 42 is rotatably connected to the first support rod 411 and the second support rod 412 so that it can rotate relative to the upper support 41 to move closer to the upper support 41. The lower support 42 is rotatably connected to the first support rod 411 and the second support rod 412. When the recliner frame is in the folded state, the straight support structure 413 moves to bring the first support rod 411 and the second support rod 412 closer together, so that the upper support 41 can be folded in the left and right directions to occupy less space.

[0075] In some alternative embodiments, the first support rod 411 and the second support rod 412 are arranged opposite each other in the left-right direction. When the recliner frame is in the unfolded state, both first cross braces 4131 extend in the left-right direction to provide support between the first support rod 411 and the second support rod 412. When the recliner frame is in the folded state, the two first cross braces 4131 may have a small included angle or be parallel to each other.

[0076] Optionally, when the recliner frame is folded, the first cross brace 4131, which is rotatably connected to the first support rod 411, rotates in the direction toward the first support rod 411, and the first cross brace 4131, which is rotatably connected to the second support rod 412, rotates in the direction toward the second support rod 412, so that the straight support structure 413 moves toward the inside of the support frame 4, further reducing the longitudinal dimension of the support frame 4, which is beneficial to the miniaturization of the recliner frame.

[0077] For example, please continue to see Figure 4 and Figure 6When the lower support 42 rotates relative to the upper support 41, it rotates around the tenth axis c1 along the first rotation direction r0. The first support rod 411 and one first cross brace 4131 rotate around the eleventh axis c2. The two first cross braces 4131 rotate around the twelfth axis c3. The second support rod 412 and another first cross brace 4131 rotate around the thirteenth axis c4. When the recliner frame is folded, the first cross brace 4131 rotates around the eleventh axis c2 along the third rotation direction r2, and the second cross brace 4231 rotates around the thirteenth axis c4 along the fourth rotation direction r3.

[0078] There are various ways in which the upper bracket 41 and the side bracket 1 can be rotatably connected. For example, this embodiment provides one way in which the upper bracket 41 and the side bracket 1 can be rotatably connected. Figure 2 As shown, the upper support 41 has a first rotating shaft 7, and the side support 1 has a second rotating shaft (not shown in the figure). The first rotating shaft 7 and the second rotating shaft are coaxially rotatably connected, allowing the upper support 41 to rotate relative to the side support 1. Optionally, the second rotating shaft is located at the position where the front support leg 11 and the rear support leg 12 are rotatably connected, and the axis of rotation of the front support leg 11 and the rear support leg 12 coincides with the axis of rotation of the upper support 41 relative to the side support 1. This reduces the complexity of the recliner frame. For example, the first rotating shaft 7 includes two rotating parts (not shown in the figure), one rotating part connected to the front support leg 11 and the other rotating part connected to the rear support leg 12. The two rotating parts are coaxially rotatably connected to achieve the rotatable connection between the front support leg 11 and the rear support leg 12.

[0079] In this embodiment, two first rotating shafts 7 are provided so that they can be rotatably connected to the second rotating shafts of the two sets of side supports 1. In some optional embodiments, please refer to... Figure 2 Each first rotating shaft 7 is connected to a support block 8. The extension direction of the support block 8 is the same as the extension direction of the first support rod 411 and the second support rod 412. The first support rod 411 and the second support rod 412 are correspondingly connected to the two support blocks 8, so as to rotate relative to the front support leg 11 and the rear support leg 12 via the first rotating shaft 7 and the support block 8. For example, the second adapter 6 is rotatably connected to the end face of the first rotating shaft 7 facing away from the second rotating shaft.

[0080] Since the upper support 41 and the side support 1 are rotatably connected, in order to limit the position of the upper support 41 relative to the side support 1 when the recliner frame is in the unfolded state, in one embodiment, the recliner frame also includes a locking structure (not shown in the figure). The locking structure is provided on one of the upper support 41 and the side support 1 and can be detachably connected to the other to limit the rotation of the upper support 41 relative to the side support 1, thereby locking the upper support 41 and enabling the upper support 41 to be used for support.

[0081] In one embodiment, the locking structure can be a locking pin, which can be movably disposed on the first rotating shaft 7 (or the second rotating shaft) along the axial direction of the first rotating shaft 7 (or the second rotating shaft). The second rotating shaft (or the first rotating shaft 7) is provided with a locking hole, and the locking pin can be inserted into the hole, thereby restricting the relative rotation between the first rotating shaft 7 and the second rotating shaft, and realizing the locking of the upper bracket 41 and the side bracket 1.

[0082] In other embodiments, the locking structure includes an electromagnetic brake installed within the first rotating shaft 7 (or the second rotating shaft). The actuating part of the electromagnetic brake can extend out of or retract from the first rotating shaft 7 (or the second rotating shaft) under the action of a driving force. The second rotating shaft (or the first rotating shaft 7) is provided with a locking hole. When the actuating part extends out of the first rotating shaft 7 (or the second rotating shaft), it can be inserted into the locking hole to restrict the relative rotation between the first rotating shaft 7 and the second rotating shaft, thereby locking the upper bracket 41 and the side bracket 1.

[0083] For example, such as Figure 5 As shown, the lower support 42 includes a third support rod 421 with one end rotatably connected to the first support rod 411, and a fourth support rod 422 with one end rotatably connected to the second support rod 412. A second support structure 423 is provided between the third support rod 421 and the fourth support rod 422. The second support structure 423 includes two second horizontal support rods 4231 with one end rotatably connected to each other. The other ends of the two second horizontal support rods 4231 are rotatably connected to the other ends of the third support rod 421 and the fourth support rod 422, respectively. When the recliner frame is in the folded state, the second support structure 423 moves to bring the third support rod 421 and the fourth support rod 422 closer together. By providing the second support structure 423, the lower support 42 can be folded in the left-right direction.

[0084] In some alternative embodiments, the third support rod 421 and the fourth support rod 422 are arranged opposite each other in the left-right direction. When the recliner frame is in the unfolded state, both second cross braces 4231 extend in the left-right direction to provide support between the third support rod and the second support rod 412. When the recliner frame is in the folded state, the two second cross braces 4231 may have a small included angle or be parallel to each other.

[0085] Optionally, when the recliner frame is folded, the second cross brace 4231, which is rotatably connected to the third support rod 421, rotates in the direction toward the third support rod 421, and the second cross brace 4231, which is rotatably connected to the fourth support rod 422, rotates in the direction toward the fourth support rod 422, so that the second cross brace 423 moves toward the inside of the support frame 4, further reducing the longitudinal dimension of the support frame 4, which is conducive to the miniaturization of the recliner frame.

[0086] For example, please continue to see Figure 5The third support rod 421 and one second cross brace 4231 rotate about the fourteenth axis d1. Two second cross braces 4231 rotate about the fifteenth axis d2. The fourth support rod 422 and another second cross brace 4231 rotate about the sixteenth axis d3. When the recliner frame is folded, the rotation direction of the second cross brace 4231 connected to the third support rod 421 is the same as the rotation direction of the first cross brace 4131 connected to the first support rod 411, and the rotation direction of the second cross brace 4231 connected to the fourth support rod 422 is the same as the rotation direction of the first cross brace 4131 connected to the second support rod 412.

[0087] In some optional embodiments, when the recliner frame is folded, the lower support 42 folds backward and moves closer to the upper support 41, while the upper support 41 and the lower support 42 fold downward and move closer to the front support leg 11 or the rear support leg 12, and retract with the front support leg 11 and the rear support leg 12 in the left and right directions. This allows the retraction in the left and right directions and the retraction in the front and back directions to be carried out simultaneously, achieving bidirectional folding and improving folding efficiency. The dimensions of the recliner in both the length and width directions are relatively small, and the overall volume is greatly reduced, making it easy to store and carry the recliner and providing high flexibility.

[0088] The recliner frame provided in this embodiment is used in the example of converting the recliner frame from an unfolded state to a folded state. Figure 6 and Figure 11 As shown, the lower support 42 is controlled to rotate around the tenth axis in the first rotation direction r0 until the lower support 42 contacts or is parallel to the upper support 41. During this process, the front support leg 11, the rear support leg 12, the first linkage assembly 2, and the second linkage assembly 3 do not move. At this time, the recliner frame is in a relaxed position. Figure 7 and Figure 12 As shown, the first step of folding is complete. Next, control the upper support 41 and the lower support 42 to rotate simultaneously, specifically rotating around the fourth axis a4 along the second rotation direction r1, as shown. Figure 8 As shown, before the upper support 41 moves to the vicinity of the rear support leg 12, the front support leg 11, the rear support leg 12, the first linkage component 2, and the second linkage component 3 are all stationary, until the recliner frame is in position. Figure 8 and Figure 13 As shown in the image, complete the second step of folding.

[0089] Then, the front support leg 11 and the rear support leg 12 can be controlled to move closer together, or the rotating connection ends of the first linkage 21 and the second linkage 22 can be controlled to move along the X direction, or the cross brace structure 30 can be controlled to close. Specific operations can be flexibly selected according to the actual situation. During this process, such as... Figure 8 , Figure 9 , Figure 13 and Figure 14As shown, the first linkage 21 rotates about the first axis a1 along the fifth rotation direction r4, and the second linkage 22 rotates about the third axis a3 along the sixth rotation direction r5. One side support 1, the first support rod 411, and the third support rod 421 move along the O direction, and the other side support 1, the second support rod 412, and the fourth support rod 422 move along the P direction to move closer to the center of the recliner frame, thereby obtaining the following... Figure 10 and Figure 15 The structure shown completes the folding of the recliner frame.
