Description

Technical Field

[0001] This utility model relates to the field of massage equipment technology, and in particular to a massage chair backrest adjustment mechanism. Background Technology

[0002] With the improvement of people's living standards and the enhancement of health awareness, massage chairs, as a type of home appliance that can provide a comfortable massage experience and relieve physical fatigue, have been favored by more and more consumers. Currently, there are already some massage chairs on the market. However, the adjustment angle of the massage chairs on the market makes it impossible for the waist and back to fully extend, resulting in the massage chair not being able to massage the waist area. At the same time, the position of the motor for back massage cannot be adjusted. Therefore, our company has re-developed the technology of this massage chair to achieve a multi-angle and multi-position adjustment design, which can better fit the human body. Utility Model Content

A cylinder is installed at the bottom of the support, and an adjustment mechanism is provided on one side of the cylinder. The adjustment mechanism is connected to the massage frame through a support frame. The massage frame includes three parts: a leg section, a waist section, and a backrest. A motor frame is installed on the backrest. A guide rail is provided inside the motor frame, and a massage motor is placed inside the guide rail. The motor frame is connected to the cylinder below through a limiting frame.

[0005] Preferably, the massage motor is equipped with rollers, which are disposed within a guide rail, and the massage rollers on the massage motor have a U-shaped design.

[0006] Preferably, the gear of the massage motor meshes with the transmission gear, which is mounted on one side of the massage wheel, and the massage motor drives the massage wheel to perform an oscillating motion.

[0007] Preferably, the adjustment mechanism includes a primary cylinder and a secondary cylinder, which are hinged sequentially. The primary cylinder connects to the support frame and the secondary cylinder, and the other end of the secondary cylinder connects to the leg.

[0008] Preferably, the motor frame is S-shaped.

[0009] Beneficial effects: This utility model adopts the above-mentioned technical solution to provide a massage chair backrest adjustment mechanism, which has the following characteristics: the adjustment mechanism is connected to the massage frame, which drives the entire massage frame to adjust multiple angles, and then cooperates with the cylinder to adjust the backrest. At the same time, a movable massage motor is set at the backrest position of the massage frame, and the massage motor moves to achieve multi-position massage of the backrest. Attached Figure Description

[0010] Figure 1 This is a three-dimensional structural diagram of the present invention.

[0011] Figure 2 : This is a bottom view of the structure of this utility model. Detailed Implementation

[0012] like Figures 1-2 The massage chair backrest adjustment mechanism shown includes a support 1, a massage frame 2, and an adjustment mechanism 3. A cylinder 4 is installed at the bottom of the support 1, and the adjustment mechanism 3 is provided on one side of the cylinder 4. The adjustment mechanism 3 is connected to the massage frame 2 through a support frame 5. The massage frame 2 includes three parts: a leg section, a waist section, and a backrest 21. A motor frame 6 is installed on the backrest 21. A guide rail 61 is provided on the inner side of the motor frame 6, and a massage motor 62 is placed in the guide rail 61. The lower part of the motor frame 6 is connected to the cylinder 4 through a limiting frame.

[0013] The specific support frame 1 is used to support the entire massage chair. A cylinder 4 is set at the bottom of the support frame 1, which can be used to control the angle of the backrest 21. At the same time, it works with the adjustment mechanism 3 to control the angle adjustment of the entire massage frame 2. After the massage frame 2 is adjusted according to the adjustment mechanism 3, the angle of the backrest 21 is adjusted again by the cylinder 4 to achieve a secondary adjustment of the backrest 21. The shape of the massage chair can be adjusted according to needs. A motor frame 6 is installed on the backrest 21. A massage motor 62 is set on the motor frame 6 via a guide rail 61. The massage motor 62 massages the backrest. The massage motor 62 moves within the guide rail 61 to massage multiple positions on the back.

[0014] To further explain, the massage motor 62 is equipped with rollers 63, which are disposed inside the guide rail 61, and the massage rollers 64 on the massage motor 62 are U-shaped.

[0015] Specifically, the massage motor 62 moves within the guide rail 61 via the roller 63, and the massage roller 64 has a U-shaped design to achieve back swing massage, massaging multiple positions on the back.

[0016] To further explain, the gear 65 of the massage motor 62 meshes with the transmission gear 66, which is mounted on one side of the massage wheel 64. The massage motor 62 drives the massage wheel 64 to perform an oscillating motion.

[0017] Specifically, the gear 65 of the massage motor 62 meshes with the transmission gear 66, and the gear 65 drives the transmission gear 66 to make a swinging motion, thereby massaging the back.

[0018] To further explain, the adjustment mechanism 3 includes a primary cylinder 31 and a secondary cylinder 32. The primary cylinder 31 and the secondary cylinder 32 are designed to be hinged in sequence. The primary cylinder 31 is connected to the support frame 5 and the secondary cylinder 32, and the other end of the secondary cylinder 32 is connected to the leg.

[0019] The specific design of the adjustment mechanism 3 uses a first-stage cylinder 31 and a second-stage cylinder 32 to drive the movement of the legs and waist. When the waist position is raised, it will affect the angle of the backrest. After combining with the cylinder 4, the position of the backrest is further adjusted.

[0020] To further explain, the motor frame 6 has an S-shaped design;

[0021] The specific motor bracket 6 is S-shaped. After the massage motor 62 is positioned on the guide rail 61, it can help adjust the intensity of the massage by the massage motor 62, and at the same time, it can adjust the distance between the massage motor 62 and the back.
