[0001] The utility model relates to the field of massagers, and particularly to a driving mechanism for a leg massage component. Background Art

[0002] For people who sit for long hours working and studying, massage can make blood circulation smooth, relieve back pain and prevent diseases, improve sleep quality, relieve overall fatigue, improve posture and exercise a healthy body. To overcome the inconvenience of manual massage, massagers or massage devices have been developed in recent years to achieve massage through mechanical movement, including leg massage.

At the same time, after multi-stage transmission, part of the driving force will be lost. If a high-power motor is used, a larger installation area is required and the energy consumption is also higher. If not, the massage strength will be weak and the best massage effect cannot be achieved.

[0033] As Figures 1-5 shown, a driving mechanism of a leg massage assembly is used to drive the leg massage assembly to perform massage actions. The leg massage assembly includes a massage plate group 1 and massage rollers 2. Leg massage areas are respectively formed on the left and right sides of the massage plate group 1 for massaging the left leg and the right leg. The driving mechanism drives the massage plate group 1 to swing periodically in the front-back and up-down directions, and the rubbing action of the massage can be realized. Massage rollers 2 are arranged in the leg massage areas on both sides. Protrusions for massage are arranged on the massage rollers 2. The driving mechanism drives the massage rollers 2 to rotate, and the massage in the form of pressing can be realized.

[0034] The driving mechanism includes a driving component and a transmission component. The driving mechanism drives the massage plate group 1 and the massage rollers 2 to act through the transmission component.

[0035] The driving component includes a driving motor 31, a transmission gear 32, and a gearbox 33. The output shaft of the driving motor 31 is meshed with the transmission gear 32, and the transmission gear 32 is connected to the transmission component. The transmission gear 32 is arranged in the gearbox 33. The driving motor 31 is connected to the gearbox 33 and its output shaft extends into the gearbox 33.

[0036] The massage plate set 1 includes plate bodies on the left and right sides. A space for placing the driving components is formed between the plate bodies on the left and right sides. The driving motor 31, the transmission gear 32, and the gearbox 33 are all arranged in this space. The plate body includes a driving connection part 11 and a massage connection part 12. The driving connection parts 11 are provided on both the left and right sides. The driving connection part 11 is connected to the transmission component. The lower end of the massage connection part 12 is connected to the driving connection part 11. The massage connection parts 12 on both sides are integrally formed U-shaped plates.

[0037] The transmission component includes a transmission shaft 41, a fixed shaft 42, and an eccentric mechanism 43.

[0038] The transmission shaft 41 is passed through the gearbox 33. A bearing 51 is provided between the transmission shaft 41 and the gearbox 33. The transmission shaft 41 passes through the left and right sides of the gearbox 33 and then passes through the left and right plate bodies of the massage plate set 1 to the leg massage area. The massage rollers 2 are respectively arranged on the parts of the transmission shaft 41 passing through the left and right plate bodies of the massage plate set 1. The transmission gear 32 is connected to the transmission shaft 41. The driving motor 31 is in transmission connection with the transmission shaft 41 through the transmission gear 32. The driving motor 31 drives the transmission shaft 41 to rotate around its own axis, and the transmission shaft 41 drives the massage rollers 2 to rotate together.

[0039] The fixed shaft 42 is passed through the gearbox 33 and is fixedly arranged. The fixed shaft 42 is parallel to the transmission shaft 41. The fixed shaft 42 is located in front of or behind the transmission shaft 41 in the driving mechanism. Limiting holes 111 are opened on both driving connection parts 11. The limiting holes 111 on both sides are symmetrically opened. The fixed shaft 42 is passed through the limiting holes 111. The limiting holes 111 extend along the front-back direction of the massage plate set 1. The extending direction of the limiting holes 111 is a straight line or an arc. In this embodiment, the limiting holes 111 extend along a straight line, and the transmission rod is located on the extension line of the limiting holes 111. When the massage plate set 1 is driven to move, the massage plate set 1 slides relative to the fixed shaft 42 through the limiting holes 111. The shape and extending direction of the limiting holes 111 determine the swinging movement of the massage plate set 1, thereby controlling the amplitude of rubbing. A fixed clamping part 52 is sleeved on the fixed shaft 42. A clamping groove is opened on the fixed clamping part 52. The two side edges of the limiting holes 111 are clamped on the clamping groove of the fixed clamping part 52.

[0040] The eccentric mechanism 43 is connected to the transmission shaft 41. The eccentric mechanisms 43 are respectively connected to the two side plate bodies, and the eccentric mechanisms 43 on both sides are symmetrically arranged. When the transmission shaft 41 rotates under the limitation of the fixed shaft 42 and the limit hole 111, the eccentric mechanism 43 drives the massage plate group 1 to act. The eccentric mechanism 43 adopts an eccentric wheel. A connection hole matching the eccentric wheel is opened on the driving connection part 11. The driving connection part 11 is sleeved on the eccentric wheel through the connection hole, and the eccentric wheel can rotate in the connection hole. The eccentric wheel is circular, and a clamping groove is also opened in its radial direction. The connection hole of the driving connection part 11 is clamped on the clamping groove of the eccentric wheel. A supporting part 53 is arranged on one side of the eccentric wheel close to the gearbox 33, which is used to balance the stress when driving the massage plate group 1 to swing eccentrically and reduce vibration.

[0041] The working principle of this embodiment is specifically described as follows:

[0042] The driving mechanism is fixedly arranged at the middle position of the massage areas on both legs. At the same time, the massage plate groups 1 and the massage rollers 2 on the left and right sides are controlled to act. The driving motor 31 is started, the transmission shaft 41 starts to rotate and drives the eccentric mechanism 43 to rotate. The eccentric mechanism 43 drives the massage plate group 1 to act. The massage plate group 1 performs a periodic cyclic action in the direction perpendicular to the transmission shaft 41 under the limitation of the limit hole 111 and the fixed shaft 42, simulating the rubbing massage action. The rotation of the transmission shaft 41 drives the massage roller 2 to rotate, and through the protrusions on the massage roller 2, the pressing massage action is simulated.

[0043] The above embodiments are only used to illustrate the technical concept and characteristics of the present invention, and their purpose is to enable those who are familiar with this technology to understand the content of the present invention and implement it accordingly, and cannot be used to limit the protection scope of the present invention.
