Description

Technical Field

[0001] This utility model relates to the field of massage equipment, and more specifically, to a double-headed lever-type percussion massage mechanism. Background Technology

[0002] In existing technologies, a common approach is to use a motor-driven eccentric component to make the massage head tap. However, this structure drives a reciprocating motion, and only the tapping motion towards the body during its cycle is effective; the retraction motion, which returns the massage head to its initial position, does not produce a massage effect and is therefore an ineffective motion. This ineffective motion is unavoidable and requires additional motor energy to overcome inertia and friction, resulting in energy waste. Utility Model Content

[0003] To address the shortcomings of existing technologies, a double-headed lever-type tapping massage mechanism is provided, which can reduce energy consumption during exercise.

[0004] To achieve the above objectives, the following technical solution is provided: a double-headed lever-type tapping massage mechanism, comprising a driver, a first massage component, and a first transmission component connected to the drive end of the driver; The first transmission assembly includes a first rotating shaft, first eccentric members installed at both ends of the first rotating shaft and connected to the first massage assembly, and a rotating shaft disposed between the two first eccentric members and connected to the first massage assembly; The driver drives the first rotating shaft to rotate, which in turn drives the first eccentric components at both ends to rotate, thereby driving the two ends of the first massage assembly to swing around the rotating shaft.

[0005] In a further optimization of this utility model, the edges of the first eccentric members at both ends that are furthest from the axis of the first rotating shaft are arranged on both radial sides of the first rotating shaft.

[0006] A further optimization of this utility model is that a connector and a rubber pad are included between the first massage component and the first eccentric component; The connector is connected to the first massage component via a rubber pad; Alternatively, the connector may be connected to the first massage component and the first eccentric component via a rubber pad.

[0007] A further optimization of this utility model includes a second massage component and a second transmission component connected to the drive end of the driver; The second transmission assembly includes a second rotating shaft and second eccentric members mounted at both ends of the second rotating shaft and connected to the second massage assembly; The driver drives the second rotating shaft to rotate, and drives the second massage component to reciprocate through the second eccentric parts at both ends.

[0008] In a further optimization of this invention, the line-plane angle formed by the axis of the second rotating shaft and the mating surface of the second massage component is greater than 0 degrees and less than 90 degrees.

[0009] In a further optimization of this utility model, the second massage component is provided with a downwardly protruding bump, and a sliding groove is provided below the second massage component for the bump to slide. The protrusion is inserted into the slide groove and cooperates with the slide groove to allow the protrusion to reciprocate along the axial direction of the second rotation axis.

[0010] A further optimization of this utility model includes a one-way rotating component; The first rotating shaft is connected to the driver via a one-way rotating component; Alternatively, the second rotating shaft can be connected to the driver via a unidirectional rotating component.

[0011] A further optimization of this invention is that the driver is a dual-head driver; One end of the driver is connected to the first rotating shaft, and the other end is connected to the second rotating shaft; The driver rotates forward or backward to drive the first and second rotating shafts.

[0012] The technical solution has the following advantages: the reciprocating motion of the first massage component is realized by the first eccentric component, and the rotating shaft makes the reciprocating motion of the first massage component more stable, while reducing the energy consumption during the motion.

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, and the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0022] Reference Figure 1-7 As shown, a double-headed lever-type tapping massage mechanism includes a driver 1, a first massage component 2, and a first transmission component 3 connected to the driving end of the driver 1. The first transmission assembly 3 includes a first rotating shaft 32, first eccentric members 33 installed at both ends of the first rotating shaft 32 and connected to the first massage assembly 2, and a rotating shaft 31 disposed between the two first eccentric members 33 and connected to the first massage assembly 2; The driver 1 drives the first rotating shaft 32 to rotate, which in turn drives the first eccentric parts 33 at both ends to rotate, thereby driving the two ends of the first massage component 2 to swing around the rotating shaft 31.

[0023] like Figure 1 and Figure 2 The diagram shows a connection between the first transmission component 3 and the driver 1 of this utility model. The output end of the driver 1 is connected to the small pulley, and through the cooperation of the belt and the large pulley, it drives the first rotating shaft 32 to rotate. At the same time, the rotational motion is converted into up-and-down yaw motion through the first eccentric component 33. Compared with the prior art, the rotating shaft 31 of this utility model acts as a fulcrum. When the first eccentric member 33 on the left moves upward, it cooperates with the rotating shaft 31 to convert the upward force applied to the first eccentric member 33 on the left into a downward force applied to the first eccentric member 33 on the right. At the same time, the downward force of the first eccentric member 33 on the right side will be converted into the upward force of the first eccentric member 33 on the left side. The first eccentric members 33 at both ends cooperate with the rotating shaft 31 to reduce the consumption of ineffective energy when the first massage component 2 swings, and also reduce the power required for the driver 1 to adapt to more drivers 1 with different power. The rotating shaft 31 can effectively utilize the energy of the driver 1, increase the stability of the first massage component 2, make its swinging motion more stable, make the tapping action of the first massage component 2 smooth, and increase the force of the tapping action.

[0024] Preferably, the edges of the first eccentric members 33 at both ends that are furthest from the axis of the first rotating shaft 32 are arranged on the radial sides of the first rotating shaft 32.

[0025] The first eccentric members 33 on both sides are installed with their eccentric directions differing by 180 degrees. When the first eccentric member 33 on the left moves, the first eccentric member 33 on the right moves in the same direction and at the same time as the first eccentric member 33 on the left. The force applied by the first eccentric member 33 on the first massage component 2 on the left decreases from the maximum to the minimum. The first eccentric member 33 on the right cooperates with the first eccentric member 33 on the left, and the applied force increases from the minimum to the maximum. In this way, the first massage component 2 is driven to swing around the rotating shaft 31. The first eccentric member 33 on the left and the first eccentric member 33 on the right are only used to distinguish the two first eccentric members 33 during description. The functions of this utility model can be achieved by the two first eccentric members 33 being in opposite directions at the same time, in opposite directions at different times, or in the same direction at different times. At the same time, the difference of 180 degrees in the eccentric direction is not absolute. It can also be 179 degrees or 181 degrees, etc. The functions of this utility model can be achieved as long as the difference in the eccentric direction is not large.

[0026] Preferably, a connector 7 and a rubber pad are included between the first massage component 2 and the first eccentric component 33; Connector 7 is connected to the first massage component 2 via a rubber pad; Alternatively, the connector 7 is connected to the first massage component 2 and the first eccentric component 33 via a rubber pad.

[0027] like Figure 7 As shown, the connector 7 cooperates with the rubber pad to convert the force used to provide the swinging motion of the first eccentric member 33 into the force of up and down motion, which is transmitted to the first massage component 2 to form a tapping action; The first eccentric component 33 will generate forces in multiple directions. Rubber pads are needed to offset or reduce the wear between the connector 7 and the first eccentric component 33 and the first massage component 2. This ensures that the first massage component 2 can maintain a fixed trajectory after multiple movements, and avoids the wear after multiple movements causing gaps to form between the connector 7 and the first massage component 2, which would lead to problems such as shaking of the first massage component 2 during movement.

[0028] Preferably, it also includes a second massage component 4 and a second transmission component 5 connected to the drive end of the driver 1; The second transmission assembly 5 includes a second rotating shaft 51 and a second eccentric member 52 installed at both ends of the second rotating shaft 51 and connected to the second massage assembly 4; The driver 1 drives the second rotating shaft 51 to rotate, and drives the second massage component 4 to reciprocate through the second eccentric parts 52 at both ends.

[0029] like Figure 3-5 As shown, this invention provides a connection method between the second transmission component 5 and the driver 1. The output end of the driver 1 is a worm gear, which, in conjunction with a gear, drives another worm gear to rotate, thereby achieving transmission. This causes the second rotating shaft 51 to rotate, driving the second massage component 4 to move. The driver 1 drives the second rotating shaft 51 to rotate, and drives the second massage component 4 to reciprocate through the second eccentric parts 52 at both ends.

[0030] like Figure 4 and Figure 6 As shown, the second rotating shaft 51 rotates and the second eccentric member 52 converts the force of rotation into the force of up and down movement, thereby causing the second massage component 4 to perform up and down reciprocating motion. Meanwhile, the second eccentric component 52 can also be connected to the second massage component 4 via the curved arm, so that the second eccentric component 52 and the curved arm can move up and down in coordination, enabling the second massage component 4 to perform massage techniques such as kneading.

[0031] Preferably, the line-plane angle formed by the axis of the second rotating shaft 51 and the mating surface 41 of the second massage component 4 is greater than 0 degrees and less than 90 degrees.

[0032] Mating surface 41 can be referenced Figure 1 and Figure 3 and Figure 4 As shown, this refers to the mating surface 41 that mates radially with the second massage component 4 and the second rotating shaft 51. This mating surface 41 forms an angle with the axis of the second rotating shaft 51, and the angle α can be referenced. Figure 5 As shown; like Figure 3 and Figure 5 As shown, the second massage component 4 is mounted obliquely on the second rotating shaft 51. The oblique design causes the second massage component 4 to swing, and at the same time, it cooperates with the up and down movement of the second eccentric part 52 to realize the wide and narrow reciprocating motion of the second massage component 4, so as to realize more massage techniques.

[0033] Preferably, the second massage component 4 is provided with a downwardly protruding protrusion 8, and a groove 9 is provided below the second massage component 4 for the protrusion 8 to slide. The protrusion 8 is inserted into the slide groove 9 and cooperates with the slide groove 9 to allow the protrusion 8 to reciprocate along the axial direction of the second rotating shaft 51.

[0034] The slide groove 9 is used to fix the swing trajectory of the second massage component 4, and at the same time, it can also limit the rotation of the second massage component 4 with the second eccentric member 52. The slide groove 9 is used to fix the swing trajectory of the second massage component 4 in order to achieve a specific massage technique.

[0035] Preferably, the double-headed lever-type tapping massage mechanism also includes a one-way rotating component 6; The first rotating shaft 32 is connected to the driver 1 via a one-way rotating component 6; Alternatively, the second rotating shaft 51 can be connected to the driver 1 via a one-way rotating element 6.

[0036] like Figure 1 and Figure 6 As shown, the one-way rotating component 6 can be a one-way bearing. The first rotating shaft 32 is connected to the driver 1 through the one-way rotating component 6. When the driver 1 rotates forward, the first massage component 2 and the second massage component 4 move simultaneously. Conversely, when the driver 1 rotates in reverse, the one-way rotating component 6 rotates idly, thereby achieving the first massage component 2 remaining stationary while the second massage component 4 moves. The same principle applies when the second rotating shaft 51 is connected to the driver 1 through the one-way rotating component 6. Multiple combinations of massage techniques can be achieved through the unidirectional rotating component 6 to adapt to different massage needs; that is, a single driver 1 can achieve multiple combinations of massage techniques.

[0037] Preferably, driver 1 is a dual-head driver; One end of the driver 1 is connected to the first rotating shaft 32, and the other end is connected to the second rotating shaft 51; The driver 1 rotates forward or backward to drive the first rotating shaft 32 and the second rotating shaft 51.

[0038] like Figure 1 As shown, this invention's driver 1 has a connection method in which the first rotating shaft 32 and the second rotating shaft 51 are connected to its two ends respectively. The dual-head driver 1 reduces the space occupied by this device and can also be adapted to more compact devices; Further as Figure 1 As shown, the worm gear and helical gear work together to rotate the power transmission by 90 degrees. By changing the angle of the power transmission of the driver 1, the space occupied by the device can be further reduced to adapt to smaller massage devices.

[0039] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
