[0015] As shown in Figs. 1-2 The intelligent headrest with universal moving device includes a headrest body 1, a moving frame 2 is arranged below the headrest body 1, and a universal moving device is arranged between the headrest body 1 and the moving frame 2. The universal moving device is controlled by an intelligent control machine 3, the intelligent control machine 3 is connected with a sensor 5 through a circuit, and the sensor 5 is arranged on the upper side of the headrest body 1.

[0016] The universal moving device includes a rotating arm 6, a shaft 4 is fixedly installed at the lower end of the rotating arm 6, and the shaft 4 is rotationally connected with the moving frame 2. A moving slider 7 is connected with the upper end of the rotating arm 6, and the moving slider 7 is slidingly connected with a linear slide rail 8 fixedly installed on the lower side of a headrest bracket 9. By controlling the inclination angle of the rotating arm 6, the lifting and pitch adjustment of the headrest can be realized.

[0017] The headrest body 1 comprises a headrest bracket 9, a elastic supporting pad 10 arranged on the upper side of the headrest bracket 9, and a headrest cover 26 covering the elastic supporting pad 10. The sensor 5 is arranged on the upper side of the elastic supporting pad 10, and the headrest cover 26 is connected with the moving frame 2 through a hanging piece 27. The elastic supporting pad 10 provides basic cushioning, and the headrest cover 26 is connected with the moving frame 2 through the hanging piece 27, which facilitates disassembly and washing.

[0018] The universal moving device further comprises an elastic pull rope 11 and a servo motor 15. A transmission wheel 12 is fixedly arranged on the branch arm rotating shaft 4, and one end of the elastic pull rope 11 is wound on the transmission wheel 12. A buffer spring 13 is connected in series on the elastic pull rope 11, and two ends of the buffer spring 13 are fixedly arranged on the elastic pull rope 11. The other end of the elastic pull rope 11 is wound on a driving wheel 16 connected with the servo motor 15. The servo motor 15 changes the pulling force on the rotating branch arm 6 by winding and unwinding the elastic pull rope 11, so as to adjust the hardness of the headrest support.

[0019] The servo motor 15 comprises a servo motor A 15-1, and the driving wheel 16 comprises a driving wheel A 16-1. A positioning roller 17 is arranged on the moving frame 2. A positioning pull rope 18 is wound on the driving wheel A 16-1 at one end, and is wound around the positioning roller 17 and connected with the headrest bracket 9 at the other end. The servo motor A 15-1, the driving wheel A 16-1, the positioning roller 17 and the positioning pull rope 18 form an independent height fine adjustment mechanism, which is used for quickly and accurately positioning the height of the headrest.

[0020] The lower side of the moving frame 2 is connected with a bottom bracket 19 through a universal wheel 20. Linear sliding rails B8-2 are arranged on four side edges of the bottom bracket 19, and moving sliding blocks B7-2 are slidably arranged on the linear sliding rails B8-2. Pull rope holes 25 are arranged on four side edges of the moving frame 2.

[0021] The servo motor 15 further comprises a horizontal moving motor B 15-2 and a vertical moving motor C 15-3. The horizontal moving motor B 15-2 is connected with a horizontal moving pull rope 22 through a driving wheel B 16-2, two ends of the horizontal moving pull rope 22 are respectively arranged through the pull rope holes 25 on the left and right sides of the moving frame 2, and are connected with the moving sliding blocks B7-2 on the left and right sides of the bottom bracket 19. The vertical moving motor C 15-3 is connected with a vertical moving pull rope 23 through a driving wheel C 16-3, two ends of the vertical moving pull rope 23 are respectively arranged through the pull rope holes 25 on the front and rear sides of the moving frame 2, and are connected with the moving sliding blocks B7-2 on the front and rear sides of the bottom bracket 19. The horizontal moving motor B and the vertical moving motor C respectively wind and unwind the horizontal moving pull rope 22 and the vertical moving pull rope 23, so as to pull the moving frame 2 and the whole headrest mechanism above the moving frame 2 to move forward and backward and left and right in the horizontal plane.

[0022] The base bracket 19 is adapted to be mounted on the mattress, on which sensors that communicate with the intelligent controller 3 can be installed. The sensors on the mattress work in conjunction with the sensors 5 on the headrest to more comprehensively sense the user's full-body posture.

[0023] Specifically: After powering on the intelligent controller 3, it receives the pressure signal transmitted by the sensor 5. After processing, it controls the operation of each servo motor. The servo motor 15 drives the drive wheel 16 to rotate through the elastic cord 11, which in turn drives the transmission wheel 12. Since the elastic cord 11 is connected to both ends of the buffer spring 13, when the elastic cord 11 has a certain tension, it pulls the buffer spring 13 to generate a stretching and buffering elastic force. This force acts on the elastic cord 11, causing it to have an elastic stretching effect. This force is transmitted to the rotating support arm 6, giving it an elastic support effect. This elastic support effect is then transmitted to the headrest bracket 9, and ultimately to the headrest body 1. The user's head then perceives the elastic support effect, achieving the function of intelligent height adjustment of the headrest using the universal moving device. Based on the user's support requirements when lying flat or on their side, the intelligent controller 3 can promptly and accurately control the support height of the headrest body 1 using the universal moving device to achieve a more comfortable effect. The upper end of the rotating support arm 6 is slidably connected to the linear slide rail 8 via the movable slider 7, which will cause the headrest bracket 9 to rise and fall, achieving a more comfortable use of the headrest. The servo motor A15-1 drives the drive wheel A16-1 and adjusts the height of the headrest bracket 9 via the positioning pull rope 18. This lifting and lowering adjustment process can achieve the function of adjusting the height or low support of the headrest body 1 for the head. After the support height of the headrest body 1 is positioned, the tension of the elastic pull rope 11 can be adjusted by the servo motor 15, which can achieve the function of adjusting the soft or firm support of the headrest body 1 for the head.

[0024] By setting up a horizontal movement motor B15-2 and a vertical movement motor C15-3, the movable frame 2 can move horizontally left and right or vertically forward and backward on the base bracket 19 through the rolling of the universal wheels 20. The horizontal movement motor B15-2 drives the drive wheel B16-2 to rotate, and the linked horizontal movement pull rope 22 pulls the movable frame 2 to move left and right. Then, the front and rear sides of the movable frame 2 will drive the vertical movement pull rope 23 and the movable slider B7-2 to move left and right synchronously through the pull rope hole 25. Similarly, the vertical movement motor C15-3, with the same structure, drives the drive wheel C16-3 to rotate, and the linked vertical movement pull rope 23 pulls the movable frame 2 to move forward and backward. Then, the left and right sides of the movable frame 2 will drive the horizontal movement pull rope 22 and the movable slider B7-2 to move forward and backward synchronously through the pull rope hole 25. Through the above-mentioned movement of the movable frame 2, the headrest body 1 is linked to have the function of moving the user's head left and right or forward and backward, so that the head, neck and back have the correct sleeping posture, achieve the purpose of health care for the head and cervical spine, and promote better sleep and rest. The omnidirectional moving device has the functions of lifting support, left and right movement and forward and backward movement of the headrest body 1. Through the frequency control of the intelligent controller 3, the headrest body 1 can have a vibration function on the user's head and neck, so as to achieve a good health care effect for the user.

[0025] Its usage process is as follows: After the user lies down, their head presses on sensor 5 on the headrest body 1 and their body presses on another sensor on the mattress. Sensor 5 transmits the pressure distribution signal to the intelligent control unit 3.

[0026] Height and Firmness Adjustment: The intelligent controller 3 determines the optimal support height and firmness based on a preset algorithm. First, it activates the servo motor A15-1, quickly adjusting the headrest bracket 9 to its approximate height by extending and retracting the positioning pull cord 18. Subsequently, the main servo motor 15 operates, extending and retracting the elastic pull cord 11. The tension of the pull cord is converted into torque on the support arm pivot 4 via the transmission wheel 12, controlling the angle of the rotating support arm 6 and achieving precise height adjustment. Simultaneously, the buffer spring 13 on the pull cord is stretched or relaxed, thereby altering the overall support elasticity of the headrest. The user will feel that the headrest is both soft and supportive.

[0027] Horizontal Position Adjustment: If the system detects that the user's head is tilted to the left, the intelligent controller 3 will activate the horizontal movement motor B15-2. The motor rotates, tightening one side of the horizontal movement rope 22 via the drive wheel B16-2 and loosening the other side, thereby pulling the entire moving frame 2 a short distance to the right. This keeps the user's body basically in a straight line with their head, neck, and back, allowing the headrest to support the user's head and provide centered support for the neck and back. Similarly, the vertical movement motor C15-3 controls the front-to-back position of the headrest via the vertical movement rope 23, ensuring a certain degree of backward traction whether the user is lying on their back supporting the back of their head or on their side supporting the side of their cheek.

[0028] Health care mode: The intelligent controller 3 can control the servo motor 15 to rotate forward and backward at a specific frequency, so that the elastic rope 11 produces periodic changes in tension, which drives the headrest to produce gentle up and down vibration, so as to massage the neck and head and relax the muscles.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
