Description

Technical Field

[0002] As people's living standards improve, they will choose to go to massage places to use massage equipment to massage in their spare time to relieve the pressure of work and daily life and relax their bodies. The massage movement is the core component of the massage equipment. The massage movement usually includes a motor, a transmission shaft and a massage wheel. After the motor is started, it drives the transmission shaft. The transmission shaft drives the massage wheel to swing left and right to perform kneading massage on the human body. The vibration of the motor and the eccentric wheel drive the massage wheel to perform beating massage on the human body.

[0003] With the advancement of technology, there are more and more types of massage equipment, but the existing massage equipment still has the following defects:

[0004] 1. In the existing massage movement, when the massage wheel is driven by a motor to perform a beating massage, the radial movement stability of the eccentric wheel on the transmission shaft cannot be controlled, and the radial movement range of the transmission shaft on the shaft driven by the motor cannot be controlled, which causes the massage wheel to easily perform a large-scale massage movement during the beating massage process, resulting in a poor massage effect, which is easy to cause beating injuries to the user and reduces the user experience.

[0005] 2. The existing massage movement usually realizes the kneading massage action between the two massage wheels by the reverse contact rotation between the opposite surfaces of a pair of eccentric wheels and the swing arm on the transmission shaft, but the opposite surfaces of the eccentric wheel and the swing arm are in complete contact rotation; therefore, the friction between the opposite surfaces of the eccentric wheel and the swing arm is very large when they rotate in the reverse direction, which produces a lot of noise and a lot of wear, which will seriously consume the eccentric wheel and the swing arm, and the eccentric wheel and the swing arm need to be replaced frequently, which increases the replacement cost.

[0006] 3. The multiple groups of massage wheels in the existing massage movement have a complex structure assembly with the motor, transmission shaft, and eccentric wheel, which occupies a large space in the vertical and horizontal directions. The transmission connection between the multiple groups of massage wheels and the motor is also complex, resulting in a large overall size of the massage movement and inconvenient disassembly and assembly.

[0046] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0047] like Figure 1-7 As shown, a massage movement drive mechanism with high stability and reduced loss and noise is applied to massage devices such as massage beds and massagers. The massage movement drive mechanism includes a massage wheel assembly 10, a hammering driver 20, a hammering transmission shaft 21, a hammering eccentric wheel 22, a swing arm 30, a limit assembly, a slide rail 50 and a plurality of travel shafts 51. The slide rail 50 is extended in the massage direction of the massage device, a plurality of travel shafts 51 are provided, travel wheels 52 are provided at both ends of the plurality of travel shafts 51, and the travel shaft 51 is installed on the slide rail 50 through the travel wheels 52 and reciprocates on the slide rail 50.

[0048] The beating transmission shaft 21 is arranged in parallel with a plurality of traveling shafts 51 , and the output end of the beating driver 20 is connected to and drives the beating transmission shaft 21 .

[0049] The limiting assembly includes a coupling support seat 40 and a coupling support plate 42, wherein two coupling support seats 40 are provided, and the two coupling support seats 40 are correspondingly provided at the left and right ends close to the hammering transmission shaft 21 and the traveling shaft 51, and the coupling support plate 42 is provided in the middle of the hammering transmission shaft 21 and the traveling shaft 51. The left and right ends of the hammering transmission shaft 21 are movably connected to the coupling support seat 40 through bearings, and the middle part of the hammering transmission shaft 21 is movably connected to the coupling support plate 42 through bearings.

[0050] The front and rear end sides of the coupling support seat 40 are provided with axial holes and wheel grooves, and the left and right ends of the traveling shaft 51 are connected through the axial holes, and the traveling wheels 52 at both ends of the traveling shaft 51 are also movably arranged on the wheel grooves, so that the coupling support seat 40 can be stably installed on the traveling shaft 51, and movably installed on the slide rail 50 through the traveling wheels 52.

[0051] Moreover, a positioning plate 41 is provided on one side of the coupling support seat 40, and the lower end edge of the positioning plate 41 is movably embedded in the positioning groove 501 of the slide rail 50, so that the coupling support seat 40 is movably mounted on the slide rail 50 through the movably positioning assembly of the positioning plate 41 and the positioning groove 501. When the coupling support seat 40 follows the running shaft 51 to slide on the slide rail 50, the positioning plate 41 and the slide rail 50 are relatively movably positioned, which can improve the sliding stability of the coupling support seat 40 on the slide rail 50.

[0052] The described eccentric wheel 22 for beating is fixedly arranged on the beating transmission shaft 21, and the swing arm 30 is arranged on the top of the beating transmission shaft 21, and the lower end of this swing arm 30 is fixedly connected with an eccentric seat 31, and an eccentric hole 310 is offered on the eccentric seat 31, and the eccentric seat 31 is assembled with the eccentric wheel 22 for beating on the beating transmission shaft 21 through the eccentric hole 310, and then the purpose of beating the transmission shaft 21 transmission connection swing arm 30 is realized. Like this, by arranging the eccentric seat 31 with the eccentric hole 310 at the lower end of the swing arm 30, it is used for assembling with the eccentric wheel 22 for beating on the beating transmission shaft 21, thereby avoiding directly offering the eccentric hole 310 on the swing arm 30, avoiding the complicated operation of changing the whole swing arm 30 when changing the beating eccentric wheel 22, only the eccentric seat 31 at the lower end of the swing arm 30 needs to be replaced when changing the beating eccentric wheel 22 on the beating eccentric shaft, and the replacement cost of the structural parts is reduced, and the disassembly and assembly are convenient.

[0053] The massage wheel assembly 10 is movably mounted on a shaft disposed at the upper end of the swing arm 30, so that the massage wheel assembly 10 can follow the movement of the swing arm 30, and each swing arm 30 is provided with one main massage wheel 101 or more than two main massage wheels 101 of the massage wheel assembly 10. The beating driver 20 is fixedly mounted on the outer side of the shaft coupling support 40, and the beating driver 20 of the present application preferably adopts a motor, so that when the beating driver 20 drives the beating transmission shaft 21 to rotate, the beating transmission shaft 21 is assembled with the eccentric seat 31 of the swing arm 30 through the beating eccentric wheel 22, thereby realizing the linkage connection between the beating transmission shaft 21 and the swing arm 30, so that the beating driver 20 can drive the massage wheel assembly 10 to perform a beating massage action through the beating transmission shaft 21 and the swing arm 30.

[0054] The same side of the coupling support seat 40 and the coupling support plate 42 is provided with a limiting hole 43, and the hole width of the limiting hole 43 is extended in the beating massage direction of the massage wheel assembly 10. When the beating transmission shaft 21 is installed, the beating transmission shaft 21 is sequentially passed through the limiting holes 43 of the coupling support seat 40 and the coupling support plate 42. By correspondingly arranging the coupling support seat 40 and the coupling support plate 42 at the left and right ends and the middle of the beating transmission shaft 21, when the beating driver 20 drives the beating transmission shaft 21 to rotate, the radial motion stability and radial motion range of the two ends and the middle of the beating transmission shaft 21 are controlled respectively by the hole width of the limiting hole 43.

[0055] In this way, the beating transmission shaft 21 provided in the present application is passed through the limiting hole 43 set in the limiting assembly, so that when the beating driver 20 drives the beating transmission shaft 21 to rotate, the beating transmission shaft 21 can only move within the hole width range of the limiting hole 43, and the beating transmission shaft 21 synchronously drives the swing arm 30 and the massage wheel assembly 10 set on the swing arm 30 to perform beating massage actions within the movable range limited by the limiting hole 43 of the limiting assembly.

[0056] Compared with the previous implementation means that the massage wheel of the massage movement cannot control the stability and radial motion range of the radial massage action of the transmission shaft through the eccentric wheel, the present application can control the radial motion range of the hammering transmission shaft 21 through the limit hole 43 of the limit assembly, and then control the hammering massage action amplitude of the swing arm 30 and the massage wheel assembly 10 on the swing arm 30 assembled on the hammering transmission shaft 21. Controlling the radial motion stability of the massage wheel assembly 10 when hammering the transmission shaft 21 can avoid the hammering massage damage to the user caused by the excessive hammering amplitude of the massage wheel assembly 10, and on the basis of providing safe massage for the user, it can also improve the massage effect.

[0057] The massage movement driving mechanism of the present application includes a kneading driver 60, a kneading transmission shaft 61 and a kneading eccentric wheel group 62, wherein the kneading driver 60 is fixedly mounted on the shaft connecting support seat 40 at the other end of the traveling shaft 51. The kneading driver 60 of the present application preferably adopts a motor, and the kneading driver 60 is connected to and drives the kneading transmission shaft 61 to rotate.

[0058] The kneading eccentric wheel group 62 is provided with two kneading eccentric wheels 621, and the two kneading eccentric wheels 621 and the swing arm 30 are both arranged in the axial length direction of the kneading transmission shaft 61, the kneading eccentric wheels 621 are fixedly connected to the kneading transmission shaft 61, the middle part of the swing arm 30 is movably connected to the kneading transmission shaft 61, and the two kneading eccentric wheels 621 are respectively arranged on the left and right sides of the swing arm 30 and are in contact with the side surfaces of the swing arm 30. Therefore, when the kneading driver 60 drives the kneading transmission shaft 61 to rotate, the two kneading eccentric wheels 621 rotate along with it and rotate circumferentially relative to the swing arm 30, thereby transmitting the swing arm 30 left and right, so that the swing arm 30 can swing axially toward the kneading transmission shaft 61 and move slightly radially.

[0059] In the present application, at least two swing arms 30 are arranged in the axial direction of the kneading transmission shaft 61, and each swing arm 30 is correspondingly provided with two kneading eccentric wheels 621. The two swing arms 30 are respectively driven by the rotation of the kneading transmission shaft 61 and the two sets of kneading eccentric wheels 621 to transmit the two swing arms 30 respectively, so that the two swing arms 30 are relatively swung or reversely swung in the axial direction of the kneading transmission shaft 61, thereby realizing the kneading and massaging action on the human body.

[0060] In addition, an eccentric pulley 33 and an eccentric protrusion 34 are provided on the side of the swing arm 30. Specifically, a slot hole is provided on the side of the swing arm 30, and the slot hole is used to movably install the eccentric pulley 33. The eccentric pulley 33 is partially embedded in the slot hole, and the eccentric pulley 33 partially protrudes from the side of the swing arm 30. In addition, the eccentric protrusion 34 is formed by protruding outside the side of the swing arm 30, and the eccentric protrusion 34 and the swing arm 30 are integrally formed, and the eccentric protrusion 34 is roughly in the shape of a semi-cylinder or a hemisphere. At least one eccentric pulley 33 and one eccentric protrusion 34 are provided on the same side of the swing arm 30.

[0061] Therefore, when the kneading drive shaft 61 is driven to rotate by the kneading driver 60, the kneading drive shaft 61 synchronously drives the two kneading eccentric wheels 621 on the left and right sides of the swing arm 30, so that the two kneading eccentric wheels 621 rotate circumferentially relative to the eccentric pulleys 33 and the eccentric protrusions 34 on the left and right sides of the swing arm 30. The swing arm 30 contacts the side surface of the swing arm 30 through the eccentric pulleys 33 and the eccentric protrusions 34, so that the swing arm 30 drives the massage wheel assembly 10 to perform kneading and massaging actions in the axial direction of the kneading drive shaft 61.

[0062] In this way, the present application performs contact transmission between the kneading eccentric wheel group 62 and the left and right sides of the swing arm 30, and when the kneading driver 60 drives the kneading transmission shaft 61 to rotate, the kneading transmission shaft 61 drives the kneading eccentric wheel group 62 to drive the swing arm 30 to swing and make the massage wheel assembly 10 perform kneading massage. In addition, by arranging the eccentric pulley 33 and the eccentric convex part 34 on the side of the swing arm 30 to perform contact transmission with the left and right sides of the swing arm 30, the eccentric pulley 33 arranged on the swing arm 30 can reduce the friction between the kneading eccentric wheel 621 and the side of the swing arm 30, and the eccentric convex part 34 arranged can reduce the contact area between the kneading eccentric wheel 621 and the left and right sides of the swing arm 30.

[0063] Compared with the previous implementation method of direct and complete contact transmission between the kneading eccentric wheel 621 and the left and right sides of the swing arm 30, the present application can reduce the friction between the kneading eccentric wheel 621 and the left and right sides of the swing arm 30 and reduce the contact area, thereby reducing the transmission noise and mutual wear between the kneading eccentric wheel 621 and the swing arm 30, slowing down the consumption of the kneading eccentric wheel 621 and the swing arm 30, saving replacement costs, and improving the massage quality of the massage wheel assembly 10.

[0064] In order to further improve the kneading massage effect, the front and rear sides of the swing arm 30 of the present application are provided with connecting arms 32 for connecting the main massage wheels 101 of the massage wheel assembly 10. The front and rear sides of the swing arm 30 refer to the directions in which the massage movement driving mechanism slides back and forth on the slide rail 50. By providing the main massage wheels 101 on the connecting arms 32 on the front and rear sides of the swing arm 30, when the two swing arms 30 swing, the main massage wheels 101 on the front sides of the two swing arms 30 swing towards each other, while the main massage wheels 101 on the rear sides of the two swing arms 30 swing in the opposite direction, thereby performing diversified kneading massage on the human body.

[0065] The massage movement driving mechanism of the present application arranges the structural components such as the beating eccentric wheel 22, the kneading eccentric wheel 621 and the swing arm 30 in the axial length direction of the beating transmission shaft 21 and the kneading transmission shaft 61, connects the main massage wheel 101 through the connecting arm 32 on the front and rear sides of the swing arm 30, and provides a connecting shaft support seat 40 at both ends of each transmission shaft, so as to facilitate the installation of the driver; the structure is simple and compact, and it is easy to disassemble and assemble, and the size of the whole machine is reduced in both horizontal and vertical dimensions.

When the user is massaging, the buffer massage wheel 71 supports part of the user's body, increases the force area of ​​the user's body on the massage device, buffers the body support pressure, and improves the user's massage experience.

[0068] The neck massage wheel 72 is arranged in the axial direction of the kneading transmission shaft 61 and between the two swing arms 30. One or more neck massage wheels 72 are arranged. The neck of the human body can be further supported and massaged by the neck massage wheel 72, thereby increasing the force-bearing area of ​​the neck of the human body and further improving the neck massage effect.

[0069] The back massage wheel 73 is arranged in the axial direction of the kneading transmission shaft 61 and on the opposite sides of the two swing arms 30. The back massage wheel 73 has a plurality of rotating drum wheels, and the two ends of the plurality of rotating drum wheels are connected with circular plate wheels, and the plurality of rotating drum wheels are arranged around the circumference of the circular plate wheel to form the back massage wheel 73. By movably sleeved the circular plate wheel on the kneading transmission shaft 61, the back massage wheel 73 can freely rotate on the kneading transmission shaft 61. When the massage movement driving mechanism is installed on the massage bed, the back massage wheel 73 can follow the sliding of the massage movement driving mechanism and then roll on the massage bed, thereby rolling massage the back of the human body, further improving the massage effect.
