[0002] As people's living standards gradually improve, sofas, as a lifestyle enjoyment product, are increasingly entering the homes of ordinary people.

[0003] Traditional sofas have a fixed backrest angle, forcing people to maintain only one posture while sitting, which can easily lead to fatigue after prolonged sitting. Existing sofas with adjustable backrest angles generally suffer from cumbersome and complex structures, limited adjustment angles, inflexible adjustment, and limited functionality. To address this, a sofa with an arbitrarily adjustable backrest angle is provided (see patent number: 201811241843.5). This sofa includes several chair units, each comprising a sofa frame assembly and an angle adjustment mechanism. The sofa frame assembly includes a base, a seat frame, and a backrest. The base... The sofa comprises two base side plates, each with a front mounting portion and a rear mounting portion. The seat frame includes two seat frame side plates, and the back frame includes two back frame side plates. The angle adjustment mechanism includes a support plate and an arc-shaped guide rail. One outer end of the support plate is fixedly connected to the inner side of the rear mounting portion, and the other outer end of the support plate has a sliding protrusion. One outer end of the arc-shaped guide rail is connected to the inner side of the seat frame side plate, and the other inner end is connected to the outer side of the back frame side plate. The sofa of this application can achieve arbitrary angle adjustment of the backrest body through its sofa frame assembly and angle adjustment mechanism. The backrest body angle adjustment is flexible and convenient, and the sofa structure is sturdy and simple.

[0004] However, most of the angle-adjustable sofas currently on the market still require manual adjustment, making it difficult to adjust the angle quickly and causing inconvenience for users. In addition, many sofas do not have massage devices, requiring users to use a separate massage chair for massage when they are tired, which makes them less practical. Utility Model Content

[0005] The purpose of this utility model is to solve the problems of existing angle-adjustable sofas on the market, which mostly require manual adjustment, making it difficult to adjust the angle quickly and causing inconvenience for users. In addition, many sofas do not have a massage device, requiring users to use a separate massage chair when they are tired, which is not very practical. The present invention provides an electrically driven angle-adjustable sofa structure.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an electrically driven angle-adjustable sofa structure, including a device body, a backrest assembly is provided on one side inside the device body, and a massage assembly is provided on the top of the backrest assembly;

[0007] The backrest assembly includes an adjustment frame, a backrest body at the top of the adjustment frame, a threaded rod at the middle of the bottom of the adjustment frame, a rotating shaft inside the threaded rod, an asynchronous motor on one side of the threaded rod, and a rotating frame outside the asynchronous motor.

[0008] The massage component includes a rotating rod with a drive motor on one side, telescopic rods at the bottom of both ends of the rotating rod, multiple massage sticks at the top of the rotating rod, and a connecting shaft at the bottom of each set of massage sticks.

[0010] As a further improvement of this utility model: the base is provided with a storage box inside, and a control panel is provided on the top of one of the armrests.

[0011] As a further improvement of this utility model: both sides of the rotating frame are provided with fixed frames, and the asynchronous motor is rotatably connected to the base through the rotating frame and the fixed frames;

[0012] As a further improvement of this utility model, the adjustment frame can be angled via an asynchronous motor, a rotating frame, and a threaded rod connected to the base.

[0013] As a further improvement of this utility model: the bottom of each of the multiple sets of massage sticks is provided with a spring, and the bottom of each of the multiple sets of connecting shafts is provided with a roller.

[0014] As a further improvement of this utility model: the outer surface of the rotating rod is provided with multiple sets of rotating blocks, and the included angle between each two adjacent sets of rotating blocks is 72°.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. By using an asynchronous motor and threaded rod to extend and retract the backrest assembly, the adjustment frame and backrest body can be rotated to adjust the angle. This allows for easy electric adjustment of the backrest body angle, reducing the tediousness of manual adjustment.

[0017] 2. The massage components are designed with multiple rotating blocks on the rotating rod. The rollers at the bottom of the massage sticks cause the massage sticks to rise alternately to achieve the purpose of massage.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. The embodiments of this utility model will be described below based on its overall structure.

[0027] Please see Figures 1-6 In this embodiment of the utility model, an electrically driven angle-adjustable sofa structure includes a device body 1, a backrest assembly 2 is provided on one side inside the device body 1, and a massage assembly 3 is provided on the top of the backrest assembly 2.

[0028] The backrest assembly 2 includes an adjustment frame 201, a backrest body 202 on the top of the adjustment frame 201, a threaded rod 204 at the middle position of the bottom of the adjustment frame 201, a rotating shaft 203 inside the threaded rod 204, an asynchronous motor 206 on one side of the threaded rod 204, and a rotating frame 205 outside the asynchronous motor 206.

[0029] The massage component 3 includes a rotating rod 301, a drive motor 302 on one side of the rotating rod 301, telescopic rods 303 at the bottom of both ends of the rotating rod 301, multiple massage sticks 305 at the top of the rotating rod 301, and a connecting shaft 304 at the bottom of each set of massage sticks 305.

[0030] Please refer to this carefully. Figure 1 and 2 The device body 1 includes a base 101, a cushion 102 on the top of the base 101, armrests 103 on both sides of the cushion 102, and rubber pads 105 at the four corners of the bottom of the base 101 to support the electric angle-adjustable sofa structure and increase the stability of the device.

[0031] Please refer to this carefully. Figure 1 and 2The base 101 has a storage box 104 inside, and a control panel 106 is provided on the top of a set of armrests 103, which provides storage function for items. The control panel 106 facilitates the control operation of various components.

[0032] Please refer to this carefully. Figure 2 and 3 The rotating frame 205 has fixed frames 207 on both sides. The asynchronous motor 206 is rotatably connected to the base 101 through the rotating frame 205 and the fixed frames 207, which increases the stability of the device during use and reduces the friction of rotation.

[0033] Please refer to this carefully. Figure 2 and 3 The adjustment frame 201 can be angled with the base 101 via the asynchronous motor 206, the rotating frame 205 and the threaded rod 204, providing the ability to adjust the angle of the backrest body 202 so as to realize the automatic angle adjustment of the device.

[0034] Please refer to this carefully. Figure 4 and 5 Each of the multiple massage sticks 305 has a spring 306 at its bottom, and each of the multiple connecting shafts 304 has a roller 307 at its bottom. The spring 306 allows the massage sticks 305 to return to their original position, and the roller 307 reduces the friction between the connecting shafts 304 and the rotating block 308, thus increasing the service life of the device.

[0035] Please refer to this carefully. Figure 6 The outer surface of the rotating rod 301 is provided with multiple sets of rotating blocks 308. The included angle between each two adjacent sets of rotating blocks 308 is 72°. The rotating blocks 308 can ensure that the massage stick 305 moves up and down in a certain pattern, which improves the comfort of the massage.

[0036] The working principle of this utility model is as follows: When the angle of the backrest body 202 needs to be adjusted, the asynchronous motor 206 is started through the control panel 106. The output end of the asynchronous motor 206 drives the threaded rod 204 to rotate and extend, thereby driving the bottom of the adjustment frame 201 to rotate, and then driving the backrest body 202 to rotate, so as to adjust the angle. At the same time, when a massage is needed, the telescopic rod 303 is started through the control panel 106 to raise the rotating rod 301.

[0037] Then, the drive motor 302 is started, which drives the rotating rod 301 to rotate. Since the rotating rod 301 is equipped with multiple sets of rotating blocks 308, the rollers 307 at the bottom of the massage sticks 305 cause the multiple sets of massage sticks 305 to rise alternately to achieve the purpose of massage. After the massage is completed, the telescopic rod 303 is retracted, and the massage sticks 305 are returned to their original position by the spring 306. This device is convenient to use and simple to operate. The backrest component 2 can be electrically adjusted at will, reducing the tediousness of manual adjustment. The massage component 3 can realize the back massage function for the user, thereby increasing the practicality of the device.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
