[0048] In order to further explain the technical solution of the present invention, the present invention is described in detail below through specific embodiments.

[0049] The present invention is a foot pedal with a dual-purpose clutch device for massage and fitness, comprising a housing 1, a massage plate 2, a rotating shaft 3, a transmission assembly and a clutch mechanism;

[0050] The massage plate 2 is arranged on the upper surface of the housing 1;

[0051] The rotating shaft 3, the transmission assembly and the clutch mechanism are all arranged in the shell 1; the upper end of the rotating shaft 3 is coaxially connected to the massage plate 2; the transmission assembly is driven by an external force to drive the rotating shaft 3 to rotate; the clutch mechanism is used to connect or cut off the power transmission between the massage plate 2 and the transmission assembly, and the control part of the clutch mechanism is exposed from the shell 1 for operation.

[0052] Through the above scheme, the present invention sets a clutch mechanism on the foot pedal with massage function, and the clutch mechanism is used to connect or cut off the power transmission between the rotating shaft 3 and the transmission assembly, that is, the connection between the massage plate 2 and the transmission assembly is controllable, and the user can enable or stop the massage function according to their own needs, thereby meeting diverse usage needs; the control part of the clutch mechanism is exposed from the shell 1, and the user can switch without disassembling the shell 1, which is more convenient to operate.

[0053] refer to Figures 1 to 13 Shown is a specific embodiment of the present invention.

[0054] The housing 1 comprises an upper housing 11 and a lower housing 12, which cover each other to form a chamber for assembling a rotating shaft 3, a transmission assembly and a clutch mechanism, and a countersunk hole 13 for the massage disc 2 to cooperate with is provided on the upper surface of the upper housing 11, and the upper end of the rotating shaft 3 passes through the bottom of the countersunk hole 13 and is coaxially connected to the massage disc 2.

[0055] The massage disc 2 comprises a disc 21 and a plurality of balls 22 rotatably fitted on the disc 21. When the user performs stepping exercise and the massage function is enabled, the transmission assembly drives the shaft 3 to rotate, and the shaft 3 drives the disc 21 to rotate relative to the sole of the user's foot, and the part of the balls 22 protruding from the upper surface of the disc 21 rolls and massages the sole of the user's foot.

[0056] This embodiment also includes a bearing 4, and a mounting hole 14 for the bearing 4 is provided in the housing 1 (i.e., the lower housing 12), and the lower end of the rotating shaft 3 is rotatably fitted in the bearing 4. Since the upper end of the rotating shaft 3 is fitted with the massage plate 2, and a bearing 4 is provided at the lower end, it can be ensured that the rotating shaft 3 does not deviate from the axis when rotating, and the structure is more stable.

[0057] The clutch mechanism may act between the rotating shaft 3 and the transmission assembly, or between the rotating shaft 3 and the massage plate 2. The following description is based on the clutch mechanism acting between the rotating shaft 3 and the transmission assembly.

[0058] In practical applications, there are many kinds of "external forces" that can be used to drive the transmission component. For example, in the above background, the flywheel swing arm 10 of the stepper is directly used to drive the transmission component, that is, the transmission component is driven by the force applied by the user to the foot pedal during exercise, and then the massage plate 2 is driven. In this way, the massage plate 2 can be driven without an additional power supply, and the structure is simple and the cost is low. Of course, a separate electric drive method, such as a motor, can also be set for the transmission component, but this will increase the cost.

[0059] In this embodiment, a flywheel swing drive scheme is adopted, and the above-mentioned transmission assembly includes a bevel gear 5, a transmission gear set 6 and a driven gear 7; the clutch mechanism includes a clutch member 8 and a control device 9; the bevel gear 5 is transmission-connected to the flywheel swing arm 10 of the stepper, the driven gear 7 is rotatably mounted on the rotating shaft 3, and the transmission gear set 6 is respectively meshed with the bevel gear 5 and the driven gear 7; the clutch member 8 is non-rotatably mounted on the rotating shaft 3, and the opposite surfaces of the clutch member 8 and the driven gear 7 are provided with concave and convex parts matching each other; the control device 9 is used to change the relative position of the clutch member 8 and the driven gear 7. Since the driven gear 7 and the rotating shaft 3 can rotate relative to each other, and the clutch 8 and the rotating shaft 3 cannot rotate relative to each other, the clutch 8 can drive the rotating shaft 3 to rotate: when the clutch 8 is in contact with the driven gear 7, that is, in the engaged state, the power of the transmission assembly can be transmitted to the rotating shaft 3, thereby driving the massage disc 2 to rotate; when the clutch 8 is separated from the driven gear 7, that is, in the separated state, the power of the transmission assembly cannot be transmitted to the rotating shaft 3, the driven gear 7 rotates idly on the rotating shaft 3, and the massage disc 2 does not move.

[0060] In addition to the gear transmission method, the transmission component can also use a belt transmission method to change the direction of force and torque to meet the needs of transmitting power from the side of the foot pedal to the rotating shaft 3 where the massage plate 2 is located.

[0061] In this embodiment, a reset member 20 is further included between the housing 1 and the clutch member 8, which is used to drive the clutch member 8 to reset toward the driven gear 7, so that when the user activates the massage function, the clutch member 8 can be driven by the reset member 20 to closely contact the driven gear 7, thereby ensuring the stability of power transmission. The reset member 20 can be a spring sleeved on the lower part of the rotating shaft 3.

[0062] In this embodiment, the above-mentioned concave and convex parts include a plurality of first protrusions 71 arranged on the lower end surface of the driven gear 7 and a plurality of second protrusions 81 arranged on the upper end surface of the clutch member 8. When the driven gear 7 is engaged with the clutch member 8, the first protrusions 71 are embedded in the gaps of the second protrusions 81 so that the two can rotate synchronously.

[0063] In this embodiment, the above-mentioned rotating shaft 3 includes a cylindrical section 31 for cooperating with the driven gear 7, and a spline section 32 for cooperating with the clutch 8. The clutch 8 has a spline hole 82 matching the spline section 32. The spline section 32 has a non-circular cross-sectional shape (such as a square or other polygonal shape) to ensure that after the spline section 32 is inserted into the spline hole 82, the clutch 8 and the rotating shaft 3 cannot rotate relative to each other, but the clutch 8 can be driven by the control device 9 to move up and down on the outer periphery of the spline section 32, thereby realizing the engagement or disengagement of the clutch 8 and the driven gear 7.

[0064] In this embodiment, the above-mentioned control device 9 includes a pivot member 91 and a control component; the middle part of the pivot member 91 is pivotally engaged in the shell 1, and one end of the pivot member 91 is movably engaged in the outer periphery of the clutch member 8; the control component is arranged at the other end of the pivot member 91, and is used to drive the pivot member 91 to swing, so that the end of the pivot member 91 drives the clutch member 8 to move on the rotating shaft 3.

[0065] Furthermore, a ring 911 for engagement with the clutch 8 is provided at one end of the pivot 91, a protrusion 912 is provided on the inner wall of the ring 911, and an annular groove 83 for engagement with the protrusion 912 is provided on the outer periphery of the clutch 8, the protrusion 912 is embedded in the annular groove 83, and drives the clutch 8 to move as the pivot 91 swings, and in addition, shafts 913 rotatably engaged with the inner wall of the housing 1 are provided on both sides of the pivot 91.

[0066] The control assembly includes a turntable 92 and a knob 93. The turntable 92 is disposed inside the housing 1, and the knob 93 is disposed outside the housing 1. The turntable 92 and the knob 93 are coaxially connected, and the knob 93 can drive the turntable 92 to rotate. A circular slope 921 is disposed on the side of the turntable 92 facing the pivot 91. The circular slope 921 surrounds the center of the turntable 92 and shows a trend of increasing height until the junction of the highest point and the lowest point. The circular slope 921 contacts the end of the pivot 91 with the rotation of the turntable 92 to drive the pivot 91 to swing. The other end of the pivot 91 protrudes toward the turntable 92 to form a convex column 914, and the convex column 914 is movably matched with the circular slope 921. In addition, a spring piece 922 is provided on the side of the turntable 92 facing the shell 1, and a spherical protrusion 923 is provided on the spring piece 922. A spherical groove 15 for the spherical protrusion 923 to flexibly cooperate with is provided on the shell 1 (that is, the lower shell 12). The spherical protrusion 923 and the spherical groove 15 can realize the gear position sense when the knob 93 is rotated, which is convenient for the user to feel whether the function switch is in place.

[0067] In addition to setting the clutch 8, the clutch mechanism can also be to set the rotating shaft 3 to a pluggable structure. After the rotating shaft 3 is partially pulled out of the housing 1, the connection between the rotating shaft 3 and the driven gear 7 is disconnected, and the power can be cut off; or a section of external thread is set on the rotating shaft 3, so that the rotating shaft 3 and the driven gear 7 are threadedly connected. After the rotating shaft 3 is rotated, the rotating shaft 3 can be disengaged from the driven gear 7, thereby cutting off the power. The above two methods are to change the matching relationship between the rotating shaft 3 and the driven gear 7 in the axial direction of the rotating shaft 3, and the height space requirements in the pedal housing 1 are relatively high. In comparison, the method of setting the clutch 8 changes the position of the rotating shaft 3 in the axial direction to the lateral direction of the pedal, which has a higher utilization rate of space and a more compact product.

[0068] refer to Figures 4 to 5 As shown, the working principle of the present invention is:

[0069] When the knob 93 is rotated to the disengaged state (the massage function is turned off), the protruding column 914 is engaged with the highest point of the annular slope 921. At this time, the left end of the pivot member 91 swings downward to the lowest point, driving the clutch member 8 to move downward to the lowest point. The clutch member 8 is separated from the driven gear 7, and the power is no longer transmitted to the rotating shaft 3 (that is, the massage plate 2), and the massage function is turned off.

[0070] When the knob 93 is rotated to the engaged state (activating the massage function), the boss 914 is matched with the lowest point of the annular slope 921. At this time, under the action of the reset member 20, the clutch member 8 moves upward to the highest point until the first protrusion 71 is embedded in the gap of the second protrusion 81. The clutch member 8 is coaxially connected to the driven gear 7, and the power is transmitted to the rotating shaft 3 (that is, the massage plate 2), and the massage function is activated; and the right end of the pivot member 91 swings downward so that the boss 914 is matched with the lowest point of the annular slope 921.

[0071] The above embodiments and drawings do not limit the product form and style of the present invention. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present invention.
