[0032] A detachable pillow 9 is provided at one end of the backrest 3 away from the angle adjustment mechanism. The pillow 9 can be fixed on the backrest 3 in a convenient and detachable manner using existing technologies such as snap buckles or Velcro. The pillow 9 can be placed or removed according to the needs of the user. At the same time, the pillow 9 can also be conveniently removed from the backrest 3 for cleaning, thereby ensuring the comfort of the sofa body.

[0033] A foot support plate 4 is rotatably connected to the support base 1, a third gear 7 is fixedly connected to the foot support plate 4, the third gear 7 is meshed with a fourth gear 8, a rotating rod 6 is fixedly connected to the fourth gear 8, both the third gear 7 and the fourth gear 8 are rotatably connected to the support base 1, and a plurality of anti-skid edges 5 distributed in an array are protrudingly provided on the support base 1 and the foot support plate 4.

[0034] Example 1: Reference Figure 1 The angle adjustment mechanism includes a motor arranged on a support base 1, a first gear 14 fixedly connected to an output shaft of the motor, and a second gear 12 meshing with the first gear 14. The first gear 14 and the second gear 12 are both rotatably connected in a rotating groove, and one end of the second gear 12 close to the rotating shaft 13 is fixedly connected to the rotating shaft 13.

[0035] Working principle: The support base 1 of the sofa body is used to support the entire sofa body, and is used to support the backrest 3 and the armrest 2. According to different users and different sitting habits, and in order to adjust the user's bad sitting posture, the user can adjust the angle of the backrest 3 on the support base 1 through the angle adjustment mechanism on the support base 1, so that the user can adjust the position of the backrest 3 according to his own needs, which not only improves the comfort of the sofa body, but also prevents the user from lying directly on the backrest 3 without any support at the back spine position, causing damage to the spine and other parts of the user. When the backrest 3 rotates, the rotating shaft 13 on the backrest 3 can be inserted into the rotating groove and rotated. At the same time, as the backrest 3 rotates, the telescopic support rod 10 will be telescoped between the backrest 3 and the support base 1, and the setting of the connecting rod 11 can prevent the connection between the telescopic support rod 10 and the backrest 3 from being broken or other rigid connections, thereby facilitating the adjustment of the backrest 3, realizing the posture adjustment function of the smart sofa, and also facilitating the user to adjust through the drive of the angle adjustment mechanism, thereby improving the comfort of the user using the sofa body.

[0036] The user drives the rotation of the first gear 14 by turning on the driving motor, and the first gear 14 can drive the second gear 12 meshing therewith to rotate in the rotating groove, and as the second gear 12 rotates, the backrest 3 fixed thereto by the rotating shaft 13 will also rotate on the support base 1 with the center of the circle of the rotating shaft 13 as the center. At the same time, the user can control the forward and reverse rotation of the output shaft of the motor by the forward and reverse switch, and can control the clockwise and counterclockwise rotation of the first gear 14 and the second gear 12, and then the backrest 3 can rotate toward the direction of the support base 1 as the second gear 12 rotates, and can also rotate in the direction of the principle support base 1, so as to adjust the angle of the backrest 3, and then can facilitate the adjustment of the backrest 3 so that the sofa body can be adapted to different users, thereby improving the comfort of the user when using the sofa body.

[0037] The user can drive the fourth gear 8 to rotate by driving the rotating rod 6 to rotate. After the fourth gear 8 rotates, it can drive the third gear 7 meshing with it to rotate on the support base 1, thereby driving the foot support plate 4 to rotate on the support base 1, and the setting angle of the foot support plate 4 can be adjusted according to the user's own needs until the most comfortable position is reached with the user and the rotating rod 6 is no longer rotated, which is also convenient for the user to operate by himself. The setting of several anti-slip edges 5 increases the contact friction between the support base 1 and the foot support plate 4 when the user lies on the sofa body, preventing the user from easily slipping off the sofa body, and at the same time improving the comfort of the user when using the sofa body.

[0038] Example 2: Reference Figure 2-Figure 3 Compared with the first embodiment, the second embodiment is different in that the angle adjustment mechanism includes a cylinder 16 arranged on the support base 1 and a sliding block 15 rotatably connected to the cylinder 16, the sliding block 15 is slidably connected to the backrest 3, and the backrest 3 is provided with a sliding groove 17 for the sliding block 15 to slide.

[0039] Limit blocks are arranged at both ends of the sliding block 15 , and the side wall of the slide groove 17 is provided with a limit groove 18 for the limit blocks to slide, and the width of the limit block is smaller than the width of the sliding block 15 .

[0040] Working principle: the user can adjust the angle of the backrest 3 by driving the cylinder 16 to extend and shorten. During the extension of the cylinder 16, the sliding block 15 on the cylinder 16 will be affected by the top thrust of the cylinder 16 and move in the direction away from the support base 1 and slide along the inner wall of the slide groove 17. The backrest 3 will also rotate toward the end away from the support base 1 under the action of the driving force. At this time, the backrest 3 will gradually rotate to a state perpendicular to the support base 1. When the user drives the cylinder 16 to shorten, the cylinder 16 will drive the sliding block 15 to move in the direction close to the support base 1 and make the sliding block 15 slide in the slide groove 17, so that the backrest 3 will gradually rotate in the direction close to the cylinder 16 without being affected by the external top thrust, thereby realizing the adjustment of the angle of the backrest 3. The structure is simple and convenient for users to use the sofa body, thereby improving the comfort of users using the sofa body.

[0041] Moreover, when the sliding block 15 slides, the limiting grooves 18 at both ends are always inserted into the limiting grooves 18 and will slide along with the sliding of the sliding block 15, so that the sliding block 15 will not be separated from the sliding groove 17, thereby ensuring the stability when the cylinder 16 is driven, and further making it more stable when the user adjusts the angle of the backrest 3.

[0042] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
