[0001] The utility model relates to massage device field, concretely to a sliding rail type massage mechanism, massage cushion and sofa. BACKGROUND

[0002] The existing massage cushion includes a cover assembly and a sliding rail type massage mechanism arranged inside the cover assembly. The sliding rail type massage mechanism generally includes a sliding rail and a massage core, the massage core is slidably arranged on the sliding rail, a motor and a motor control module are installed inside the massage core, and the motor control module is connected to an external power supply and a human-computer interaction module (such as a key module) through flexible wires.

[0003] The existing massage cushion has the following problems: when the massage core slides up and down along the sliding rail, the flexible wires will move back and forth with the massage core. After long-term use, the flexible wires are prone to breakage, disconnection and other abnormal conditions, affecting the service life of the massage mechanism. Moreover, in order to ensure that the inside of the cover assembly has space for the flexible wires to move back and forth, the cover assembly needs to be provided with a support skeleton, resulting in an increase in the volume of the massage cushion, which also easily causes the massage cushion to be hard at the support skeleton, affecting comfort.
