Description

Technical Field

[0001] This utility model relates to a massage sofa with an inflatable, electrically driven movable lumbar support. Background Technology

[0002] A massage sofa is a type of sofa chair with a massage function. A lumbar support cushion is a common accessory on massage sofas, used to provide support for the user's lower back and improve sitting comfort. However, the support strength and position of the lumbar support cushions on most massage sofas on the market cannot be adjusted according to the user's body shape, sitting posture, and lumbar support needs. This makes it difficult for users of different heights, weights, or sitting postures (such as sitting upright, leaning back, or reclining) to obtain support that conforms to their own lumbar curve. Some users may even experience their lower back being unsupported or over-supported due to improper lumbar support placement, which can easily lead to lower back fatigue or discomfort with prolonged use.

[0003] In addition, the lumbar cushions that come with existing massage sofas usually need to be removed and stored when not in use. Traditional massage sofas either have non-removable lumbar cushions or require users to find a place to put them after removal, which takes up surrounding space. Moreover, the removal and installation of lumbar cushions is relatively cumbersome. For commercial massage sofas installed in public places such as shopping malls and airports, there is a possibility of them being lost. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides a massage sofa with an inflatable and electrically movable lumbar support cushion. The support strength and position of the lumbar support cushion can be adjusted according to the user's needs, thus meeting the lumbar support requirements of different users.

[0005] This utility model discloses a massage sofa with an inflatable, electrically driven movable lumbar cushion, comprising a sofa body and a lumbar cushion. The sofa body includes a backrest and a seat. The backrest is equipped with a guide rail and a walking mechanism that cooperates with the guide rail and can move up and down along the backrest. The lumbar cushion is mounted on the walking mechanism, which can drive the lumbar cushion to move up and down along the backrest, thereby adjusting the support position of the lumbar cushion. The lumbar cushion includes an airbag, which is located on the front side of the walking mechanism. The airbag is connected to an air pump and an electrically controlled valve that cooperate with the airbag to inflate and deflate. When the air pump is working, it inflates the airbag, allowing it to expand. When the electrically controlled valve is closed, it prevents the gas in the airbag from being released, maintaining the airbag pressure. When the electrically controlled valve is open, it allows the gas in the airbag to be released. The air pump and electrically controlled valve can be mounted on the walking mechanism or fixed to the sofa body and connected to the airbag through pipes. By inflating and deflating the lumbar cushion airbag, the degree of expansion of the lumbar cushion can be adjusted, thereby adjusting the support force of the lumbar cushion on the user's waist.

[0006] Furthermore, the lumbar support includes an elastic reset mechanism. When the airbag is inflated, the elastic reset mechanism is driven to elastically deform and stores elastic potential energy during deformation. When the airbag deflates, the deformation resets and drives the airbag to contract. The elastic reset mechanism can accelerate the contraction speed of the airbag and achieve rapid deflation.

[0007] Furthermore, the elastic reset mechanism consists of several elastic bands or tension springs wrapped around the airbag. The elastic bands or tension springs are stretched when the airbag is inflated. When the electronically controlled valve is opened, the elastic bands or tension springs can cause the airbag to contract rapidly, thereby accelerating the deflation speed.

[0008] Furthermore, the lumbar support includes a pressure detection mechanism for detecting the airbag pressure. The pressure detection mechanism is linked with the air pump and the electronic control valve. Through the cooperation of the pressure detection mechanism, the air pump and the electronic control valve, the airbag can be adjusted to the desired air pressure. It can also be used to achieve adaptive adjustment of the airbag pressure, such as maintaining the airbag pressure at a constant pressure value or within a pressure range. When the pressure is greater than or less than the set value, the airbag is automatically inflated or deflated to achieve constant pressure.

[0009] Furthermore, the lumbar support includes an outer cover fitted over the outside of the airbag. The airbag is connected to the walking mechanism through the outer cover, or the airbag and the walking mechanism are connected and fitted together inside the outer cover. The outer cover can fix and protect the airbag, preventing it from rupturing. The outer cover can be made of leather.

[0010] Furthermore, the lower end of the guide rail includes an extension section that bends forward to extend below the seat or backward to extend below the backrest. When the lumbar cushion is not needed, it does not need to be removed. The lumbar cushion is moved to the underside of the seat or backrest by the walking mechanism for hiding and storage. The operation is simple and convenient. In addition, by cooperating with the deflation and contraction function of the airbag, it can also reduce the space occupied under the seat or backrest, and can also reduce the requirement for the size of the gap between the back of the seat and the front of the backrest, making the overall structure and shape of the sofa more compact and beautiful.

[0011] Furthermore, there are two guide rails, which are respectively connected to both sides of the walking mechanism. Each guide rail includes a rack arranged along its length. The walking mechanism includes gears on both sides and a motor for driving the gears to rotate in both directions. The forward and reverse rotation of the motor drives the gears to rotate in both directions, thereby driving the walking mechanism and the lumbar pad as a whole to move up and down along the guide rail.

Detailed Implementation

[0013] This utility model provides an embodiment of a massage sofa with an inflatable, electrically driven movable lumbar support, such as... Figure 1-6 As shown, the sofa includes a main body and a lumbar cushion 1. The main body includes a backrest 21 and a seat (not shown in the figure). The backrest 21 is equipped with a guide rail 3 and a walking mechanism 4 that cooperates with the guide rail 3 and can move up and down along the backrest 21. The lumbar cushion 1 is mounted on the walking mechanism 4, which can drive the lumbar cushion 1 to move up and down along the backrest 21, thereby adjusting the support position of the lumbar cushion 1. The lumbar cushion 1 includes an airbag 11, which is located on the front side of the walking mechanism 4. The airbag 11 is connected to an air pump (not shown in the figure) and an electronically controlled valve (not shown in the figure) that cooperate with the airbag 11 to inflate and deflate it. (Not shown in the image) When the air pump is working, it inflates the airbag 11, allowing the airbag 11 to expand. The solenoid valve is used for the electric control valve. When the electric control valve is closed, it can prevent the gas in the airbag 11 from being released on its own and maintain the pressure of the airbag 11. When the electric control valve is open, it can release the gas in the airbag 11. The air pump and the electric control valve can be set on the walking mechanism 4 and move synchronously with the walking mechanism 4, or they can be fixed on the sofa body and connected to the airbag 11 through pipes. By inflating and deflating the airbag 11 of the lumbar cushion 1, the degree of expansion of the lumbar cushion 1 can be adjusted, thereby adjusting the support force of the lumbar cushion 1 on the user's waist.

[0014] The lumbar support 1 includes an elastic reset mechanism. When the airbag 11 is inflated, the elastic reset mechanism is driven to elastically deform and stores elastic potential energy during deformation. When the airbag 11 deflates, the deformation resets and drives the airbag 11 to contract. The elastic reset mechanism can accelerate the contraction speed of the airbag 11 and achieve rapid deflation.

[0015] In this embodiment, as Figure 3 , 4As shown, the elastic reset mechanism consists of multiple elastic bands 5 wrapped around the airbag 11. These elastic bands 5 are spaced laterally around both the airbag 11 and the traveling mechanism 4. The elastic bands 5 are stretched when the airbag 11 inflates. When the electronically controlled valve opens, the elastic bands 5 cause the airbag 11 to contract rapidly, thereby accelerating the deflation speed. In other embodiments, tension springs or other components with elastic stretching functions can also be used.

[0016] The lumbar support 1 includes a pressure detection mechanism (not shown in the figure) for detecting the air pressure of the airbag 11. The pressure detection mechanism is linked with the air pump and the electric control valve. Through the cooperation of the pressure detection mechanism, the air pump and the electric control valve, the airbag 11 can be adjusted to the desired air pressure. It can also be used to achieve adaptive adjustment of the air pressure of the airbag 11, such as keeping the pressure of the airbag 11 at a constant pressure value or within a pressure value range. When the pressure is greater than or less than the set value, the airbag is automatically inflated or deflated to achieve constant pressure.

[0017] The lumbar support 1 includes an outer cover (not shown in the figure) that is fitted over the outside of the airbag 11. The airbag 11 and the walking mechanism 4 are connected and fitted together inside the outer cover. The outer cover can fix and protect the airbag 11, preventing the airbag 11 from being damaged. The outer cover can be made of leather.

[0018] like Figure 2 As shown, the lower end of the guide rail 3 includes an extension section 31 that curves backward and extends below the backrest 21. When the lumbar support 1 is not needed, it does not need to be removed. The lumbar support 1 is moved below the backrest 21 by the walking mechanism 4 for concealment and storage (e.g., Figure 2 (As shown by the dashed line), the operation is simple and convenient, preventing the lumbar cushion 1 from being lost. Furthermore, by cooperating with the deflation and retraction function of the airbag 11, the airbag 11 can be released and then moved and retracted under the backrest 21, reducing the space occupied under the backrest 21 and also lowering the requirement for the size of the gap between the back of the seat and the front of the backrest 21 (the retracted airbag is thinner, making it easier to pass through the gap between the seat and the backrest), making the overall structure and shape of the sofa more compact and aesthetically pleasing. In other embodiments, the extension section 31 can also bend forward and extend under the seat, allowing the lumbar cushion 1 to move, hide, and be stored under the seat.

[0019] The guide rails 3 are two in number and are respectively connected to both sides of the walking mechanism 4. The guide rail 3 includes a rack 32 arranged along its length. The walking mechanism 4 includes gears 41, motors 42 and speed-changing gear sets arranged on both sides. The motors 42 are double-headed motors with reversible output shafts. Both ends of the output shaft are connected to the gears 41 located on both sides of the walking mechanism 4 through the speed-changing gear sets. The forward and reverse rotation of the motor 42 drives the gears 41 to rotate forward and reverse, thereby driving the walking mechanism 4 and the waist pad 1 to move up and down along the guide rails 3.

[0020] The above embodiments are merely one preferred embodiment of the present utility model. Ordinary changes and substitutions made by those skilled in the art within the scope of the present utility model's technical solution are all included within the protection scope of the present utility model.
