Description

Technical Field

[0001] The utility model relates to the technical field of electric sofas, in particular to an anti-pinch moving mechanism for an electric sofa. Background Art

[0002] An electric sofa is a sofa with electric functions. The posture of the sofa can be controlled by a remote control or buttons, such as adjusting the angle of the backrest and footrest to make sitting on it more comfortable. It is usually equipped with a power cord and needs to be plugged in. There are many types of electric sofas, such as single-person electric sofas, multi-person electric sofas, and electric massage sofas. The working principle of an electric sofa is mainly achieved through the internal electric push rod. First, the motor in the electric push rod starts to run, and then the rotational motion of the motor is converted into linear motion through the movement of the gears. This linear motion is the power source for pushing the sofa back or footrest up and down. When you press the remote control or the button on the sofa, the electrical signal will be sent to the control system of the electric push rod. The control system will control the start and stop of the motor according to the received signal, and then control the up and down movement of the push rod to achieve the lifting and lowering of the sofa back or footrest.

[0003] Although the existing electric sofas can achieve the effect of automatic lifting, when the backrest descends, it is impossible to limit the position of the user, resulting in the user's clothes or arms being caught in the gap between the backrest and the seat cushion. When in use, the placement board for the feet still needs to be manually pulled out and pushed back by the user, which is inconvenient. In addition, most of the placement boards are metal or plastic plates, which are uncomfortable to the feet and have no cushioning effect. At the same time, the elasticity is poor, resulting in the user's feet being uncomfortable. Therefore, an anti-pinch moving mechanism for an electric sofa is proposed to solve the above-mentioned problems. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides an anti-pinch moving mechanism for an electric sofa, which solves the problem that the user's clothes or arms are caught in the gap between the backrest and the seat cushion due to the inability to limit the user's position, and when in use, the placement plate for the feet still needs to be manually pulled out and pushed back by the user, which is quite inconvenient. In addition, most of the placement plates are metal or plastic plates, which are relatively uncomfortable to the feet and have no cushioning effect. At the same time, the elasticity is poor, resulting in the user's feet being uncomfortable.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an anti-pinch moving mechanism for an electric sofa, comprising an electric sofa body and a mounting frame, wherein the anti-pinch moving mechanism is arranged outside the electric sofa body;

[0006] The anti-pinch moving mechanism includes a mounting plate fixedly connected to the left and right sides of the electric sofa body, a first electric telescopic rod is fixedly connected to the top of the mounting plate, an inlet and outlet are opened on the left and right sides of the electric sofa body, an output shaft of the first electric telescopic rod is fixedly connected to a backrest plate, the bottom of the electric sofa body is fixedly connected to a base, a telescopic cylinder is fixedly installed on the back of the base, a telescopic end of the telescopic cylinder is fixedly connected to a moving box, pulleys are fixedly connected around the bottom of the moving box, a second electric telescopic rod is fixedly installed inside the moving box, the output shaft of the second electric telescopic rod is fixedly connected to a placement plate, a damper is fixedly connected to the top of the placement plate, and a pad is fixedly connected to the inner side of the backrest plate and the top of the backrest plate.

[0007] Furthermore, a connecting column is fixedly connected to the inner side of the mounting frame, and the front end of the connecting column is fixedly connected to the left and right sides of the electric sofa body.

[0008] Furthermore, a fixing frame is fixedly connected to the front of the mounting frame, a rotating shaft is rotatably installed on the inner side of the fixing frame, a plastic cloth for shading is wrapped around the outer surface of the rotating shaft, a ratchet is fixedly connected to the end of the rotating shaft away from the fixing frame, and a plastic belt is meshed on the outer surface of the ratchet.

[0009] Furthermore, the output shaft of the first electric telescopic rod passes through the inlet and outlet, and the number of the first electric telescopic rod is the same as that of the second electric telescopic rod.

[0010] Furthermore, the outer surface of the electric sofa body is provided with a cushion, and the top of the moving box is not closed.

[0011] Furthermore, the bottom of the base is fixedly connected to a bottom plate, and a sliding groove is provided on the top of the bottom plate.

[0012] Furthermore, the outer diameter of the bottom plate is larger than the outer diameter of the base, and the pulley is slidably connected to the slide groove.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] 1. The anti-pinch moving mechanism of the electric sofa is provided with an anti-pinch moving mechanism. When the user lowers the backrest of the electric sofa body through the remote control, the first electric telescopic rod will be started synchronously, so that the two backrest boards are pressed against each other to provide support for the user's waist. At the same time, the user's position can be well limited to avoid being pinched due to disorderly movement. Moreover, only the telescopic cylinder and the two electric telescopic rods need to be started in sequence to push the moving box out of the base platform. At the same time, the placement plate is moved upward to provide support for the user's feet. In addition, with the cooperation of the damper and the pad, the placement plate can have a buffering effect and at the same time, its overall elasticity is enhanced, thereby improving the comfort of the user's feet.

[0015] 2. The anti-pinch moving mechanism of the electric sofa cooperates with the rotating shaft, plastic cloth, ratchet and plastic belt. When the user wants to rest for a while by leaning on the backrest of the electric sofa body, he can continuously pull down the plastic belt, so that the ratchet rotates clockwise, and then lower the plastic cloth on the outer surface of the rotating shaft to shield the user from most of the external light, avoid the influence of external light, and improve the quality of his rest.
