The massage rollers also have multiple intensity adjustment functions to meet the needs of deep relaxation. They are mainly composed of the chair body, travel rails, massage mechanism and control system.

[0003] In existing massage chairs, the horizontal force generated by the massage rollers when applied at medium or higher intensity pushes the body forward. Due to the lack of an active upper body fixation structure, the body is prone to detaching from the backrest, resulting in problems such as reduced massage intensity and misalignment of the massage trajectory, thus the efficiency of use needs to be improved.

[0004] Therefore, it is necessary to propose a massage chair with a backrest vertical travel guide to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a massage chair with a backrest vertical travel guide rail, in order to solve the problem that in existing massage chairs, when the massage rollers apply medium or higher force, the horizontal component force generated will push the human body forward. Due to the lack of an active upper body fixation structure, the body is prone to detach from the backrest, resulting in problems such as reduced massage intensity and misalignment of the massage trajectory, and the efficiency of use needs to be improved.

[0026] This utility model provides, for example Figures 1-6 The massage chair shown includes a backrest 1 and a seat 2. The seat 2 is placed on the ground, and the backrest 1 is installed at the corner of the top of the seat 2. The backrest 1 has a certain tilt angle, which is convenient for the human body to lean on. In actual use, structures such as electric push rods can be set to adjust the tilt angle of the backrest 1 to meet various usage needs.

[0027] Side grooves 11 are provided on the inner walls of both sides of the chair back 1. A rack and pinion guide rail 12 is fixedly installed inside the side grooves 11. A drive box 13 is provided inside the chair back 1. Gears 14 are installed at the four corners of the drive box 13. The gears 14 mesh with the corresponding rack and pinion guide rails 12. A motor structure that cooperates with the gears 14 is provided inside the drive box 13 to drive the gears 14 to rotate. Since the gears 14 mesh with the corresponding rack and pinion guide rails 12, the drive box 13 can move. The motor, electric push rod and other structures are connected to the power supply of the place of use (such as a shopping mall).

[0028] The drive box 13 is equipped with a massage mechanism 15, which includes a motor, cam and other structures, and can massage the user's back. The massage mechanism 15 is a common existing technology and will not be described in detail here.

[0029] During massage, the massage mechanism 15 moves up and down along the user's back with the cooperation of the drive box 13, gear 14 and rack and pinion guide rail 12, so as to achieve multi-position massage.

[0030] Furthermore, the backrest 1 is equipped with a covering structure (not shown in the figure), including a main covering layer and an internal cushioning layer. The main covering layer can be made of knitted fabric (such as high-elastic nylon-spandex fabric), and the internal cushioning layer can be made of polyurethane (PU) foam, etc., to shield and protect the internal massage mechanism 15, rack and pinion guide rail 12, drive box 13 and other components, while ensuring massage comfort and user experience. It can be adjusted according to actual needs.

[0031] In addition, a covering structure can also be installed on seat 2 to ensure comfort.

[0032] Considering that in actual use, the horizontal component of the massage mechanism 15, when applied with medium or higher intensity, will push the body forward, and due to the lack of an active upper body fixation structure, the body is prone to detaching from the backrest 1, causing problems such as reduced massage intensity and misalignment of the massage trajectory. To improve massage efficiency, a lead screw 7 is rotatably installed at the top of the backrest 1. Both ends of the lead screw 7 are threadedly connected to slides 8, and the slides 8 are attached to the wall of the backrest 1, so that the slides 8 can only move along the axial direction of the lead screw 7 and will not rotate. Furthermore, a ball bearing or other structure can be installed at the contact point between the slides 8 and the backrest 1 to reduce friction.

[0033] A drive motor 10 is fixedly installed on the side wall of the chair back 1, and a lead screw 7 is fixedly connected to the drive shaft of the drive motor 10. The drive motor 10 is connected to the power supply of the place of use (such as a shopping mall).

[0034] An electric push rod 9 is fixedly installed at the bottom of the slide seat 8. A fixed block 3 is fixedly connected to the telescopic end of the electric push rod 9. The electric push rod 9 drives the fixed block 3 to move up and down, that is, to move back and forth along the length of the backrest 1. Specifically, a button that works with the electric push rod 9 can be set on the side of the seat 2 or other easily accessible location. The user can control the electric push rod 9 through the button. If the massage chair has an intelligent voice function, the electric push rod 9 can also be controlled by voice commands. Adjustments can be made according to the specific usage. Manual control and voice control are common existing technologies and will not be described in detail here.

[0035] Specifically, the threads at both ends of the lead screw 7 have opposite directions of rotation (not shown in the figure), and the two slides 8 are respectively engaged with these two threads with different directions of rotation; when the drive motor 10 drives the lead screw 7 to rotate forward, under the limiting engagement of the backrest 1 wall (the slides 8 will not rotate), the two slides 8 move towards each other along the width direction of the backrest 1 (axial direction of the lead screw 7), and under the engagement of the electric push rod 9, the two fixed blocks 3 move towards each other synchronously; when the drive motor 10 drives the lead screw 7 to rotate in reverse, under the limiting engagement of the backrest 1 wall (the slides 8 will not rotate), the two slides 8 move away from each other along the width direction of the backrest 1 (axial direction of the lead screw 7), and under the engagement of the electric push rod 9, the two fixed blocks 3 move away from each other synchronously, thereby realizing that the two fixed blocks 3 move towards each other or away from each other along the width direction of the backrest 1 (axial direction of the lead screw 7).

[0036] A rotating frame 4 is rotatably mounted on the fixed block 3. The rotating frame 4 is U-shaped, with a groove at the end of the rotating frame 4 away from the fixed block 3. There is a certain damping between the fixed block 3 and the rotating frame 4. When adjusted by external force, it can rotate. After the external force stops, the rotating frame 4 will not rotate arbitrarily.

[0037] A shaft 5 is fixedly connected to the rotating frame 4, and the shaft 5 passes through the groove of the rotating frame 4. An arc plate 6 is rotatably mounted on the shaft 5. Since the rotating frame 4 is rotatably mounted on the fixed block 3, the concave side of the arc plate 6 can face up or down, and the arc plate 6 can swing about the shaft 5 as an axis, which facilitates storage and other operations.

[0038] Furthermore, the arc plate 6 has an arc-shaped portion 601 and a right-angle portion 602 at one end near the rotating frame 4, with the arc-shaped portion 601 located near the recessed side of the arc plate 6. When the right-angle portion 602 is attached to the inner wall of the groove of the rotating frame 4 (refer to...), Figure 6 (It fits into the groove of the rotating frame 4 near the fixed block 3), the arc plate 6 will not continue to swing counterclockwise, which can play a limiting role.

[0039] In actual use, the concave side of the control arc plate 6 faces upward, and the right-angled part 602 is attached to the inner wall of the rotating frame 4 (see reference). Figure 6 The user leans back against the chair back 1 and rests their armpits on the curved plate 6. Since the curved plate 6 is curved, it has a limiting function. At this time, the curved plates 6 on both sides cooperate to actively fix the upper body and prevent the body from leaning forward during the massage, especially when the intensity is medium or higher, so as to avoid problems such as the decrease of massage intensity and the misalignment of the massage trajectory, and ensure the massage effect.

[0040] Since the two fixing blocks 3 can move towards or away from each other along the width direction of the chair back 1 (axial direction of the lead screw 7), and the fixing blocks 3 can move up and down, the height of the arc plate 6 and the distance between the two arc plates 6 can be adjusted, making it suitable for users of different body types.

[0041] In addition, the arc plate 6 is provided with a covering structure (not shown in the figure), and the arc plate 6 has a certain width and an appropriate overlap area to ensure comfort.

[0042] Furthermore, considering that the headrests on existing chair backs 1 are usually fixed designs, i.e., located at the top of the chair back 1, but for some shorter users, when only using the massage chair for rest, the headrest position is too high and it is difficult to provide effective support. Therefore, in this utility model, since the rotating frame 4 is rotatably mounted on the fixed block 3, when support is needed, the arc plate 6 is rotated so that its concave side faces down, and then the arc plate 6 is swung downwards until its concave side abuts against the rotating frame 4, forming... Figure 2 The two curved plates 6 are close together and combined to form a headrest structure. Because its height is adjustable, it is suitable for users of different body types.
