DETAILED DESCRIPTION

[0027] Combine the following Figure 1-Figure 6 The present invention is described in detail.

[0028] A massage chair includes a back frame 10, the back frame 10 is provided with a backrest 80, and also includes a side massage device 20, a first drive device 30 and a second drive device 40, specifically:

[0029] The side massage device 20 is arranged on the side of the back frame 10, and the side massage device 20 includes a sliding seat 201 and a massage part 202. The sliding seat 201 is arranged on the side of the back frame 10 so as to slide up and down, and one end of the massage part 202 is hinged to the sliding seat 201;

[0030] The first driving device 30 is installed on the sliding seat 201, and its output end is hinged to the massage part 202, and is used to drive the massage part 202 to rotate to massage the shoulders, arms or chest of the human body, and

[0031] One end of the second driving device 40 is mounted on the back frame 10, and the output end of the second driving device 40 is transmission-connected to the sliding seat 201, for driving the sliding seat 201 to slide up and down relative to the back frame 10, so as to push the massage part 202 in the up and down direction to massage the shoulders, arms or chest of the human body.

[0032] When in use, the first driving device 30 drives the massage part 202 to press the user to simulate the acupressure massage effect, and drives the position of the sliding seat 201 through the second driving device 40, thereby adjusting the height of the side massage device 20 to adapt to users of different heights, expand the scope of use, and improve customer experience.

[0033] In this embodiment, a pair of guide rails 50 is formed between the two sliding seats 201 and the back frame 10, and the side massage device 20 is driven to move along the pair of guide rails by the second driving device 40. Furthermore, guide rails 50 are provided on both sides of the back frame 10, and the sliding seat 201 is provided with rollers 60 adapted to the guide rails 50. A fixed tube 70 is also included, and both ends of the fixed tube 70 are respectively connected to the two sliding seats 201, and the output end of the second driving device 40 is hinged to the fixed tube 70. By driving the fixed tube 70, the side massage devices 20 on both sides are synchronously driven, thereby reducing the number of the second driving devices 40 and reducing the production cost.

[0034] In this embodiment, the second driving device 40 includes a second motor 401 and a slider 402 that is transmission-connected to the output end of the second motor 401, and the slider 402 is hinged to the fixed tube 70. Furthermore, a second transmission screw is provided at the output end of the second motor 401, and the external thread of the second transmission screw is adapted to the slider 402. By controlling the forward and reverse rotation of the second motor 401, based on the thread matching between the second transmission screw and the slider 402, the slider 402 is raised and lowered, thereby driving the side massage device 20 to move up and down through the fixed tube 70. Figure 5 As shown, at this time, the side massage device 20 is in the upper limit position, that is, position A; the second motor 401 is started to drive the second transmission screw to rotate, thereby driving the side massage device 20 to move downward until it is as shown in FIG. Figure 6 As shown in the middle position B, the side massage device 20 is at the lower limit position; if the side massage device 20 needs to be adjusted to move up to position A, the second motor 401 is started to reverse.

[0035] In this embodiment, the first driving device 30 includes a first motor 301, a slide seat 302 slidably adapted to the slide seat 201, and a push rod 303. The first motor 301 is installed on the slide seat 201, and the output end of the first motor 301 is hinged to the slide seat 302. The two ends of the push rod 303 are respectively hinged to the slide seat 302 and the massage part 202. The massage part 202 includes a plurality of massage joints 2021 that are mutually transmission-connected. The massage joint 2021 close to the slide seat 201 is hinged to the slide seat 201 and the push rod 303, and each massage joint 2021 is provided with an arc-shaped massage surface 2022.

[0036] Specifically, a first transmission screw is provided at the output end of the first motor 301, and the first transmission screw is threadedly connected to the slide 302. The first motor 301 controls the first transmission screw to rotate counterclockwise or clockwise, and based on the threaded transmission relationship between the first transmission screw and the slide 302, the slide 302 is controlled to move forward and backward relative to the slide 201, and then the push rod 303 is controlled to push the massage part 202 or pull back the massage part 202, so as to control the massage part 202 to move back and forth within a preset trajectory, thereby achieving acupressure massage effect.

[0037] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable those skilled in the art to understand the content of the present invention and implement it, and they cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
