Description

Technical Field

[0001] The utility model relates to the technical field of seats, in particular to a massage movement installation structure and a nursing chair thereof. Background Art

[0002] Many massage mechanisms on the current market are fixed when installed on the back of a chair, and the massage head always protrudes from the plane of the chair back. As a result, when the user is sitting normally without using the massage function, the massage head always presses against the user's waist. Over time, this causes the user's waist to be very uncomfortable and even painful.

[0003] At the same time, due to the different heights, weights and stress levels of the users, the fixed massage movement installation cannot provide different massage intensity experiences for different people, which greatly reduces the comfort of the product. Utility Model Content

[0004] In order to solve the above problems, the purpose of the present invention is to provide a massage movement installation structure, which supports the massage movement through an adjustable airbag and hinges the massage movement on the backrest frame, so that during the inflation and deflation of the adjustable airbag, the massage movement can rotate along the hinged end so that the massage head can extend out of the backrest frame or be hidden in the backrest frame, solving the discomfort of the fixed massage head pressing against the waist for a long time when not massaging; at the same time, the height of the airbag can be adjusted by the amount of inflation and deflation, thereby controlling the rotation angle of the massage movement to achieve control of the massage intensity and improve the comfort of the product.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions:

[0006] A massage movement installation structure is characterized by comprising a backrest frame, an adjustable airbag arranged at the lower inner side of the backrest frame, a massage movement assembly and a control main box, wherein the massage movement assembly comprises a movement and a massage head installed on the movement, wherein:

[0007] The control main box is connected to the adjustable air bag through the air guide tube and is suitable for inflating and deflating the adjustable air bag; and is electrically connected to the movement of the massage movement assembly and is suitable for controlling the operation of the massage head;

[0008] A massage mechanism assembly is hinged to the backrest frame and located in front of the adjustable airbag;

[0009] The adjustable airbag is configured to bulge on the back of the massage core assembly when inflated so that the massage head protrudes from the plane of the backrest frame, and to dent when deflated so that the massage core assembly can rotate along the hinge end under the action of external force to press the massage head into the backrest frame.

[0010] In the above technical solution, the back support of the massage movement assembly is provided with an adjustable airbag, the massage movement assembly is hinged on the backrest frame, and the control main box (with air pump, air valve and other components inside) inflates and deflates the adjustable airbag through the air duct. The amount of inflation and deflation can control the size of the bulging volume of the airbag, especially in the height direction. When inflated, the volume of the airbag slowly increases and presses against the back of the massage movement assembly, so that the massage movement assembly rotates outward along the hinged end, and the massage head extends out of the backrest frame to act on the human waist; when deflated, the volume of the airbag slowly decreases. After the user leans on the massage head, the massage movement assembly rotates inward along the hinged end, and the massage head is hidden on the inside of the backrest frame, thereby effectively solving the discomfort of the fixed massage movement when it is not massaging, because the massage head always presses against the user.

[0011] Moreover, when the massage head extends out of the backrest frame, the angle of the massage head can be changed by adjusting the volume of the airbag, especially the height, so as to control the massage intensity.

[0012] In addition, the airbag supports the massage movement assembly, so users will have a certain degree of elastic support when using it, thereby improving the comfort during massage.

[0013] It should also be noted here that the airbag massage movement installation structure can be applied to the backrests of various chairs such as sofas, leisure chairs, office chairs, mahjong chairs and nursing chairs.

[0014] Preferably, the backrest frame and the massage core assembly are rotatably connected via a pair of connecting shafts. In this technical solution, the backrest frame and the massage core assembly are rotatably connected via connecting shafts, which is simple in structure and easy to assemble and disassemble. Other effective hinged structures can also be used, such as clamping the massage core assembly with a rotating clamp.

[0015] Preferably, the lower front portion of the backrest frame is formed with two curved tubes, and the pair of connecting shafts are connected between the lower portions of the curved tubes and the lower portions of the massage mechanism assembly on both sides. In this technical solution, the connecting shafts are arranged on the lower portions of the two curved tubes, creating a large space between the two curved tubes and the rear portion of the backrest frame, thereby facilitating the concealment of the massage head.

[0016] Preferably, the massage movement assembly further includes movement-fixing sponges, each having an assembly slot defined therein. The movement fits within the slot, with the massage head extending therefrom. The sponges are provided with connection holes on both sides of the lower portion thereof for engaging with the connecting shaft. In this technical solution, the sponges are used to secure the movement, improving assembly stability and facilitating connection with the connecting shaft.

[0017] Preferably, the bottom surface of the assembly slot is provided with a plurality of positioning grooves, and the back of the movement is provided with a plurality of positioning blocks or positioning posts that cooperate with the positioning grooves. In this technical solution, the plurality of positioning grooves cooperate with the positioning blocks or positioning posts to improve the tightness of the fit between the movement and the movement fixing and shaping pads, effectively preventing the movement from radially disengaging. It should be noted that the movement and the movement fixing and shaping pads are bundled together to prevent the risk of the movement disengaging during rotation.

[0018] Preferably, the movement-fixing sizing cotton is provided with an internal iron or wooden frame, with mounting holes for engaging the connecting shaft provided on the lower sides of both sides of the internal iron or wooden frame. In this technical solution, the internal iron or wooden frame is formed inside the movement-fixing sizing cotton to enhance the structural strength of the movement-fixing sizing cotton, increase its service life, and provide a more stable rotational fit with the connecting shaft.

[0019] Preferably, a plurality of first reinforcing ribs are provided at the bottom of the backrest frame. In this technical solution, the provision of the first reinforcing ribs improves the structural strength of the backrest frame and facilitates the installation of the control main box.

[0020] Preferably, a plurality of second reinforcing ribs are provided on the lower back portion of the backrest frame. In this technical solution, the provision of the second reinforcing ribs improves the structural strength of the backrest frame.

[0035] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, unless otherwise specified, "plurality" means two or more, unless expressly limited otherwise.

[0036] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0037] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature. Example 1:

[0038] like Figures 1 to 8 The massage movement installation structure shown in the figure includes a backrest frame 1 and an adjustable airbag 2 arranged at the lower inner part of the backrest frame 1, a massage movement assembly and a control main box 3. The massage movement assembly includes a movement 4 and a massage head 5 installed on the movement 4, wherein,

[0039] The control main box 3 is connected to the adjustable air bag 2 through the air guide tube, and is suitable for inflating and deflating the adjustable air bag 2; and is electrically connected to the movement 4 of the massage movement assembly, and is suitable for controlling the operation of the massage head 5;

[0040] The massage mechanism assembly is hinged to the backrest frame 1 and is located in front of the adjustable airbag 2;

[0041] The adjustable airbag 2 is configured to bulge on the back of the massage movement assembly when inflated so that the massage head 5 extends beyond the plane of the backrest frame 1, and to be concave when deflated so that the massage movement assembly can rotate along the hinge end under the action of external force to press the massage head 5 into the backrest frame 1.

[0042] In the above technical solution, the back support of the massage movement assembly is provided with an adjustable airbag, the massage movement assembly is hinged on the backrest frame, and the control main box (with air pump, air valve and other components inside) inflates and deflates the adjustable airbag through the air duct. The amount of inflation and deflation can control the size of the bulging volume of the airbag, especially in the height direction. When inflated, the volume of the airbag slowly increases and presses against the back of the massage movement assembly, so that the massage movement assembly rotates outward along the hinged end, and the massage head extends out of the backrest frame to act on the human waist; when deflated, the volume of the airbag slowly decreases. After the user leans on the massage head, the massage movement assembly rotates inward along the hinged end, and the massage head is hidden on the inside of the backrest frame, thereby effectively solving the discomfort of the fixed massage movement when it is not massaging, because the massage head always presses against the user.

[0043] Moreover, when the massage head extends out of the backrest frame, the angle of the massage head can be changed by adjusting the volume of the airbag, especially the height, so as to control the massage intensity.

[0044] In addition, the airbag supports the massage movement assembly, so users will have a certain degree of elastic support when using it, thereby improving the comfort during massage.

[0045] It should also be noted here that the airbag massage movement installation structure can be applied to the backrests of various chairs such as sofas, leisure chairs, office chairs, mahjong chairs and nursing chairs.

[0046] Furthermore, the backrest frame 1 and the massage core assembly are rotatably connected via a pair of connecting shafts 6. In this technical solution, the backrest frame and the massage core assembly are rotatably connected via connecting shafts, which has a simple structure and is easy to assemble and disassemble. Other effective hinge structures can also be used, such as clamping the massage core assembly with a rotating clamp.

[0047] Furthermore, two curved tubes 7 are constructed on the lower front side of the backrest frame 1, and the pair of connecting shafts 6 are connected between the lower portions of the curved tubes 7 and the lower portions of the massage mechanism components on both sides. In this technical solution, the connecting shafts are arranged on the lower portions of the two curved tubes, creating a large space between the two curved tubes and the rear portion of the backrest frame, making it easier to hide the massage head.

[0048] Furthermore, the massage movement assembly includes movement-fixing sponges 8, which are provided with mounting slots 9. The movement 4 fits within these slots, and the massage head 5 extends out of these slots. Connecting holes 10 are provided on the lower sides of the movement-fixing sponges 8, which mate with the connecting shaft 6. In this technical solution, the movement-fixing sponges are used to secure the movement, improving its assembly stability and facilitating its connection to the connecting shaft.

[0049] Furthermore, the bottom surface of the assembly slot 9 is provided with a plurality of positioning grooves 11, and the back of the movement 4 is provided with a plurality of positioning blocks 12 or positioning posts 13 that cooperate with the positioning grooves 11. In this technical solution, the plurality of positioning grooves cooperates with the positioning blocks or positioning posts to improve the tightness of the fit between the movement and the movement fixing and shaping pads, effectively preventing the movement from radially disengaging. It should be noted that the movement and the movement fixing and shaping pads are bundled together to prevent the risk of the movement disengaging during rotation.

[0050] Furthermore, a built-in iron frame or wooden frame 14 is provided inside the movement fixing and shaping cotton 8, and assembly holes 15 are provided on both sides of the lower portion of the built-in iron frame or wooden frame 14 to cooperate with the connecting shaft 6. In this technical solution, the built-in iron frame or wooden frame is formed inside the movement fixing and shaping cotton to improve the structural strength of the movement fixing and shaping cotton, extend its service life, and make its rotational cooperation structure with the connecting shaft more stable.

[0051] Furthermore, a plurality of first reinforcing ribs 16 are provided at the bottom of the backrest frame 1. In this technical solution, the provision of the first reinforcing ribs improves the structural strength of the backrest frame and facilitates the installation of the control main box.

[0052] Furthermore, a plurality of second reinforcing ribs 17 are provided on the lower back portion of the backrest frame 1. In this technical solution, the provision of the second reinforcing ribs improves the structural strength of the backrest frame. Example 2:

[0053] like Figures 9-11 The nursing chair shown includes a massage movement mounting structure in the first embodiment, a seat cushion and armrests, and a buttocks-beautifying airbag 300 is provided on the inner side of the armrests on both sides. The control main box 3 is connected to the adjustable airbag 2 and the buttocks-beautifying airbag 300 through the air guide tube 100, and is connected to the movement and the power adapter 200 through the wire. Figure 11 The remote controller controls the main box 3 through buttons, and then controls electronic components such as the air pump and valve to adjust the inflation and deflation of the airbag.

[0054] In this specific implementation, the existing movement is fixedly installed, and the massage head always protrudes from the plane of the chair backrest, causing users to feel uncomfortable when not using the seat massage function. The above solution hinges the bottom of the movement to the backrest frame with a connecting shaft, so that the entire movement can rotate relative to the backrest frame, and utilizes the inflation and deflation function of the back airbag to achieve the effect of the airbag acting on the movement to effectively support the user's waist during massage. When not massaging, the movement is hidden inside the backrest, so that the user will not feel pressure on the waist due to the movement massage head when sitting for a long time, thereby improving the comfort of the chair.

[0055] By using circuits and IC control, the amount of inflation and deflation can be controlled to achieve the volume (especially the height) of the airbag, thereby controlling the angle of rotation of the movement to achieve control of the massage intensity.

[0056] In addition, after the airbag is inflated, it will have a certain extrusion elasticity using the principle of air pressure. The inflated airbag will hold up the movement, and the user will have a certain elastic support when using it, thereby improving the comfort during massage.
