[0033] As a household relaxation device, massage chairs have been widely used in the market in recent years. However, the foot bearing plate 102 installed on the foot massage device 100 of traditional massage chairs is a fixed platform, and then the sole of the foot is massaged by rolling massage rollers. The traditional design ignores the massage needs of the ankle joint. Since the foot bearing plate 102 is fixedly arranged, the ankle joint cannot move synchronously with the massage components, so discomfort is likely to occur at the ankle during long-term use.
[0034] To solve the above technical problems, an embodiment of the present application provides a foot massage device 100 and a massage chair.
[0035] Referring to Figure 1 、 Figure 2 and Figure 3 As shown, an embodiment of the present application provides a foot massage device 100, including a bottom substrate 101 and a foot bearing plate 102 provided on the bottom substrate 101 for supporting the sole of the foot; a connection support 103 near the rear of the sole of the foot and a support structure 104 near the front of the sole of the foot are provided on the bottom substrate 101; a rotating shaft 105 with an extending direction intersecting the placing direction of the sole of the foot is provided on the foot bearing plate 102, an eccentric wheel 106 is sleeved on the rotating shaft 105, and the eccentric wheel 106 is connected to an installation hole 107 opened on the connection support 103; a sliding surface 108 is provided on the support structure 104, and a sliding portion 109 placed on the sliding surface 108 is provided on the foot bearing plate 102; the eccentric wheel 106 is driven to rotate in the installation hole 107, and drives the sliding portion 109 to move on the sliding surface 108 through the foot bearing plate 102, so that the foot bearing plate 102 can drive the sole of the foot to swing reciprocally along the eccentric direction of the eccentric wheel 106.
[0036] It should be noted that the bottom substrate 101 of the embodiment of the present application can be horizontally arranged, and the foot bearing plate 102 is located above the bottom substrate 101. Among them, the rotating shaft 105 is installed above the foot bearing plate 102, a window is opened on the foot bearing plate 102, and the connection support 103 can pass through the window from below the foot bearing plate 102 to above the foot bearing plate 102 and is rotatably connected to the eccentric wheel 106 sleeved on the rotating shaft 105.
[0037] Among them, the foot bearing plate 102 and the bottom substrate 101 have two connection parts.
[0038] It should be noted that the setting position of the eccentric wheel 106 is close to the center line of the sole. Preferably, the connecting line between the geometric center of the eccentric wheel 106 and the geometric center of the sliding part 109 is parallel to the center line of the sole, so that the eccentric wheel 106 and the sliding part 109 are located on the center line of the foot bearing plate 102 in the front-back direction to ensure the stability of the foot bearing plate 102 during the swinging process.
[0039] An eccentric wheel 106 is rotatably arranged on the foot bearing plate 102. The foot bearing plate 102 is connected to the bottom substrate 101 through the eccentric wheel 106 as a driving connection part, so that the foot bearing plate 102 can perform eccentric motion, thereby driving the movement of the ankle joint of the foot. The sliding part 109 arranged on the foot bearing plate 102 abuts against the sliding surface 108 arranged on the bottom substrate 101 to form a front-end support connection part, which can enhance the overall bearing capacity of the foot bearing plate 102 on the one hand, and ensure that the rear end of the foot bearing plate 102 can swing up and down on the other hand, that is, enable the ankle joint to move.
[0040] Further, referring to Figure 5 As shown, the eccentric wheel 106 has a rotating toroidal surface 110 in the circumferential direction. The connecting support 103 is sleeved on the rotating toroidal surface 110 through the mounting hole 107; the central axis of the rotating toroidal surface 110 and the central axis of the rotating shaft 105 have a preset distance, forming an eccentricity of the eccentric wheel 106 in the radial direction.
[0041] It should be noted that the rotating shaft 105 extends in the horizontal direction, and the central axis of the rotating toroidal surface 110 and the central axis of the rotating shaft 105 have a preset distance. Therefore, the rotating toroidal surface 110 of the eccentric wheel 106 generates an eccentric distance in the radial direction during rotation. Since there is no other connection structure at the rear end of the foot bearing plate 102, the foot bearing plate 102 will swing up and down due to the radial eccentricity during the rotation of the eccentric wheel 106. At this time, the up and down movement of the ankle joint of the foot can be realized.
[0042] Further, referring to Figure 3 And Figure 5 As shown, the central axis of the rotating toroidal surface 110 and the central axis of the rotating shaft 105 have a preset included angle, forming an eccentricity of the eccentric wheel 106 in the axial direction. Due to the inclined setting of the rotating toroidal surface 110, the eccentric wheel 106 can not only generate an up and down eccentricity during rotation, but also cause the foot bearing plate 102 to shift left and right, realizing the combined swing of the foot bearing plate 102 in the left-right and up-down directions, effectively improving the massage effect of the foot massage device 100 on the foot.
[0043] It should be noted that the specific size of the preset included angle between the central axis of the rotating toroid 110 and the central axis of the rotating shaft 105 is not limited, and those skilled in the art can set it according to the required swing amplitude. Exemplarily, the preset included angle is 7-12°.
[0044] The foot massage device 100 provided by the embodiment of the present application includes a bottom substrate 101 and a foot bearing plate 102 provided on the bottom substrate 101 for supporting the sole; a connecting support 103 near the rear part of the sole and a support structure 104 near the front part of the sole are provided on the bottom substrate 101; a rotating shaft 105 with an extending direction intersecting the placing direction of the sole is provided on the foot bearing plate 102 of the embodiment of the present application, an eccentric wheel 106 is sleeved on the rotating shaft 105, and the eccentric wheel 106 is connected to an installation hole 107 opened on the connecting support 103; a sliding surface 108 is provided on the support structure 104 of the embodiment of the present application, and a sliding part 109 placed on the sliding surface 108 is provided on the foot bearing plate 102; the eccentric wheel 106 of the embodiment of the present application is driven to rotate in the installation hole 107, and drives the sliding part 109 to move on the sliding surface 108 through the foot bearing plate 102, so that the foot bearing plate 102 can drive the sole to swing reciprocally along the eccentric direction of the eccentric wheel 106. Therefore, during the massage process, the embodiment of the present application can enable the foot bearing plate 102 to realize reciprocating swing, enable the ankle to move along with the massage device, meet the massage requirements of the user for the ankle, and improve the comfort of foot massage.
[0045] Refer to Figure 4 As shown, as an optional implementation manner, a guiding groove 112 with an extending direction intersecting the placing direction of the sole is provided on the support structure 104; the sliding part 109 is a sliding shaft 111, and the sliding shaft 111 penetrates through the guiding groove 112 along the extending direction of the sole and abuts against the sliding surface 108 formed on the guiding groove 112.
[0046] It should be noted that the contact between the sliding shaft 111 and the sliding surface 108 is line-plane contact, which is beneficial to reducing the contact area and the frictional resistance generated during sliding, so that the foot bearing plate 102 can move flexibly.
[0047] As an optional implementation manner, at least two massage rollers arranged at intervals along the placing direction of the sole are provided on the foot bearing plate 102.
[0048] Among them, massage protrusion parts are arranged at intervals along the circumferential direction on the massage roller, and adjacent massage protrusion parts are axially misaligned and separated.

The rotating shaft 105 is driven to drive the second massage roller 114 and the third massage roller 115 to rotate for sole massage.
[0052] Among them, the first massage rollers 113 are arranged on both sides of the eccentric wheel 106. The eccentric wheel 106 corresponds to the center of the heel, and the first massage rollers 113 arranged on both sides can perform rolling massage on the heel.
[0053] Referring to Figure 1 And Figure 6 As shown, as an alternative embodiment, it further includes a driving motor 118 and a detection module. The driving motor 118 is installed on the foot bearing plate 102 to drive the rotating shaft 105 to rotate, and the detection module is installed on the rotating shaft 105 to detect the rotating position of the rotating shaft 105.
[0054] Among them, the detection module includes a coding disk 119 and an optocoupler detection board 120. The coding disk 119 is sleeved on the rotating shaft 105, and the optocoupler detection board 120 determines the rotating position of the massage roller by detecting the rotation angle of the coding disk 119.
[0055] It should be noted that the embodiment of the present application further includes a control module.
