DETAILED DESCRIPTION

[0026] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0027] like Figure 1-9The ergonomic memory mattress shown comprises an ergonomic mattress body 1, a supporting bottom shell 4 is placed at the bottom of the ergonomic mattress body 1, and a plurality of stretching mechanisms are connected between the side of the supporting bottom shell 4 and the side of the ergonomic mattress body 1, and the stretching mechanism comprises a mounting plate 8, the mounting plate 8 is bonded to the side of the ergonomic mattress body 1, a second connecting plate 10 is installed on the surface of the mounting plate 8 through a pin, a first elongated hole 42 is opened on the side of the second connecting plate 10, a second fixed round rod 31 is installed between the inner top surface and the bottom surface of the first elongated hole 42 through screws, a stretching spring 25 and a connecting block 21 are movably sleeved on the surface of the second fixed round rod 31, two ends of the stretching spring 25 are respectively installed on the surface of the connecting block 21 and the inner bottom surface of the first elongated hole 42 through screws, a first connecting plate 9 is installed on one end of the connecting block 21 through screws, the first connecting plate 9 and the second connecting plate 10 are arranged in parallel, and the bottom end of the first connecting plate 9 is installed on the outside of the supporting bottom shell 4 through a pin. As the massage mechanism massages the human body, the ergonomic mattress body 1 moves upward after receiving the force of the massage mechanism. The electric mounting plate 8 moves synchronously while the ergonomic mattress body 1 moves. The mounting plate 8 drives the second connecting plate 10 to move synchronously through the pin shaft. The second connecting plate 10 slides in the inner wall of the connecting block 21 through the second fixed round rod 31, which is used to improve the stability of the connection between the ergonomic mattress body 1 and the supporting bottom shell 4. As the second connecting plate 10 moves upward, the length of the tension spring 25 shrinks, and the reaction force generated by the tension spring 25 pushes the second connecting plate 10. When the ergonomic mattress body 1 is not subjected to external force, the length of the tension spring 25 is reset, and the tension spring 25 is used to assist in resetting the position of the ergonomic mattress body 1.

[0028] A massage mechanism is connected between the bottom of the supporting bottom shell 4 and the inner bottom surface of the ergonomic mattress body 1, and the massage mechanism includes a first linear motor 7, which is mounted on the inner bottom surface of the supporting bottom shell 4 by screws, and a mounting plate 22 is mounted on the movable end of the first linear motor 7, one end of the mounting plate 22 is connected to a concave support member 20, one end of the concave support member 20 is mounted with a bearing seat 24 by screws, and the other end of the concave support member 20 is mounted with a motor mounting seat 34 by screws, and a driving motor 33 is mounted on the top of the motor mounting seat 34 by screws, and a lead screw 18 is installed in the movable end of the driving motor 33 and the inner ring of the bearing seat 24, and one end of the two lead screws 18 is welded and fixed, and the surfaces of the two lead screws 18 are threadedly sleeved with a screw tube 36, and a limiting mechanism is provided between the two screw tubes 36 and the supporting bottom shell 4, and the surfaces of the two screw tubes 36 are mounted with a screw The mounting block 32, the top of the two mounting blocks 32 are both equipped with a connecting rod 23 through a hinge, the second linear motor 14 is installed between one end of the two connecting rods 23 through a hinge, the movable end of the second linear motor 14 is equipped with a clamp 38 through a screw, the top plate 26 is provided above the second linear motor 14, the surface of the top plate 26 is provided with a second opening 27, the two ends of the clamp 38 extend to the inside of the second opening 27, the two ends of the clamp 38 are bent, a bearing 39 is installed between the two ends of the clamp 38, the inner rings of the two bearings 39 are tightly plugged with a rolling shaft 29, the surface of the rolling shaft 29 is provided with a plurality of massage convex points 28, the surface of the rolling shaft 29 is in contact with the bottom of the ergonomic mattress body 1, the two symmetrical sides of the second opening 27 are both equipped with a long concave piece 30 through screws, and the two ends of the rolling shaft 29 extend to the inside of the two long concave pieces 30. There are at least twelve massage convex points 28, and the twelve massage convex points 28 are arranged at equal angles. First, the first linear motor 7, the second linear motor 14 and the driving motor 33 are connected to the power switch through a wire, and then the power switch is connected to the external power supply through a wire. After the user lies on the ergonomic mattress body 1, the first linear motor 7 is operated first, and the first linear motor 7 drives the mounting plate 22 to move synchronously, and the mounting plate 22 drives the concave support member 20 to move synchronously. After the concave support member 20 is subjected to force, it drives the bearing seat 24, the two lead screws 18, the two screw tubes 36, the two mounting blocks 32 and the two connecting rods 23 to move synchronously. The two connecting rods 23 drive the second linear motor 14 to move synchronously, and the second linear motor 14 drives the rolling shaft 29 to move synchronously through the clamp 38. The rolling shaft 29 drives the massage protrusion 28 to rotate and move under the ergonomic mattress body 1. As the first linear motor 7 works, the first linear motor 7 drives the rolling shaft 29 to move longitudinally in the horizontal direction, thereby conveniently driving the rolling shaft 29 to move to the position corresponding to different parts of the human body, which is used to operate the massage mechanism according to the user's requirements to perform massage operations on parts of the human body.When massaging a part of the human body, the user first operates the driving motor 33 to turn on the power. The driving motor 33 applies a force to the two lead screws 18, so that one of the lead screws 18 rotates inside the bearing seat 24. During the rotation of the two lead screws 18, torque is applied to the two screw tubes 36. The two screw tubes 36 apply torque to the four mounting shafts 35. The four mounting shafts 35 are limited by the inner walls of the two second long holes 19. After the two screw tubes 36 are subjected to force, they drive the two screw tubes 36 to move synchronously on the surfaces of the two lead screws 18. Since the thread rotation directions of the two lead screws 18 are opposite, the two screw tubes 36 approach or move away from each other. During the movement, the two screw tubes 36 drive the mounting block 32 to move synchronously. The two mounting blocks 32 drive the connecting rod 23 to rotate in the vertical direction through the hinge, and the other ends of the two connecting rods 23 rotate at the bottom of the second linear motor 14 through the hinge, thereby facilitating the two connecting rods 23 to adjust the position of the second linear motor 14 in the vertical direction during the vertical angle adjustment process. When the two screw tubes 36 approach or move away from each other, the two screw tubes 36 drive the four installation shafts 35 to move synchronously, and the four installation shafts 35 drive the four rotating round tubes 17 to move synchronously. The four rotating round tubes 17 slide on the inner wall surface of the two second long holes 19, so that the four installation shafts 35 drive the four rotating round tubes 17 to rotate in the two second long holes 19, which is used to facilitate the synchronous movement of the two screw tubes 36. As the height of the second linear motor 14 is adjusted, the second linear motor 14 drives the rolling shaft 29 to move in the vertical direction through the clamp 38, which is used to move the rolling shaft 29 to the person. The bottom of the ergonomic mattress body 1, and then the user controls the second linear motor 14 to work, the movable end of the second linear motor 14 drives the clamp 38 to move in the horizontal direction, the clamp 38 drives the rolling shaft 29 to move in the horizontal direction, the rolling shaft 29 has friction with the bottom of the ergonomic mattress body 1, and as the rolling shaft 29 is subjected to force, it rolls at the bottom of the ergonomic mattress body 1, which is convenient for the rolling shaft 29 to apply force to the ergonomic mattress body 1, and then apply pressure to the parts of the human body to perform massage and relaxation operations, thereby being able to perform massage operations on the human body.

[0029] Both ends of the second linear motor 14 are installed with sliding tubes 13 by screws, and the first fixed round rods 2 are slidably installed inside the two sliding tubes 13, and the two first fixed round rods 2 are installed with fixed plates 3 by screws at both ends, and one end of the four fixed plates 3 is respectively installed on the inner bottom surface of the support bottom shell 4 through elastic mechanisms. The elastic mechanism includes a sliding rod 41, one end of the sliding rod 41 is installed on the bottom of the fixed plate 3 by screws, and the bottom end of the sliding rod 41 is movably sleeved with a fixed pipe 40, and the surfaces of the fixed pipe 40 and the sliding rod 41 are movably sleeved with a pressure spring 15, and the two ends of the pressure spring 15 are respectively installed on the bottom of the fixed plate 3 and the inner bottom surface of the support bottom shell 4 by screws. As the second linear motor 14 moves in the horizontal direction, the two ends of the second linear motor 14 slide on the surface of the first fixed round rod 2 through the sliding tube 13, which is used to improve the stability of the second linear motor 14 during the sliding process in the horizontal direction.

[0030] The limiting mechanism includes a mounting shaft 35 and a second elongated hole 19. The second elongated hole 19 is provided on the side of the concave support member 20. One end of the mounting shaft 35 is mounted on the surface of the screw tube 36 by means of a screw, and one end of the mounting shaft 35 extends to the inside of the second elongated hole 19. A rotating circular tube 17 is provided on the surface of the mounting shaft 35. A fixed circular ring 37 is provided on the surface of the mounting shaft 35. The two fixed circular rings 37 are in contact with the two ends of the rotating circular tube 17 respectively. As the second linear motor 14 moves in the vertical direction, the first fixed circular rod 2 drives the two fixed plates 3 to move synchronously in the vertical direction. The two fixed plates 3 drive the two pressure springs 15 to move synchronously in the vertical direction, so that the length of the pressure spring 15 is lengthened or shortened. Then the two fixed plates 3 drive the two sliding rods 41 to slide in the two fixed pipes 40, so as to improve the stability of the second linear motor 14 in the vertical direction.

[0031] The cross section of the support bottom shell 4 is concave, and a support plate 11 is installed between the two ends of the support bottom shell 4 by screws. A plurality of first openings 12 are provided on the surface of the support plate 11. The length of the rolling shaft 29 is smaller than the width of the first opening 12, and the top of the support plate 11 contacts the bottom of the ergonomic mattress body 1.
