Description

Technical Field

[0001] The present invention relates to the technical field of massage apparatuses, and particularly to an operating track structure of a massage mechanism for a convertible massage bed or chair. Background Art

[0002] Massage beds and massage chairs are commonly used equipment in families, physiotherapy centers or beauty salons, and are used to relax muscles, relieve fatigue or assist professional massage. Massage chairs mainly use the rolling force of machinery and mechanical force extrusion to perform massage. A variety of massage mechanisms are provided inside, such as massage rollers, airbags, vibration motors, etc. The massage rollers move up and down and left and right to imitate the kneading, pushing and other actions of human hands to massage parts such as the back and waist; the airbags inflate and deflate to achieve the extrusion and wrapping of various parts of the body, simulating manual pressing; the vibration generated by the vibration motor can play a role in relaxing muscles. Through the collaborative work of these massage mechanisms, the massage chair can perform all-round massage on different parts of the human body, promote blood circulation and relieve muscle fatigue. As an important equipment in the massage physiotherapy process, the massage bed provides a comfortable and stable massage experience platform for users. It is mainly applied in places such as beauty salons, physiotherapy halls, massage parlors and families. It can not only assist massage therapists in professional operations, but also enable users to enjoy the benefits of massage in a relaxed state.

[0003] Due to the large differences in functions, structures and usage scenarios between massage beds and massage chairs, it is technically difficult to directly "convert" (that is, to turn a massage bed into a massage chair or a massage chair into a massage bed). At present, some massage beds or massage chairs on the market are equipped with an electric adjustment mechanism with adjustable angles. Although the angle can be adjusted to the supine mode or the seat mode, there is no automatic massage function after adjustment. Because it is still impossible to achieve the operation of the electric massage mechanism without affecting the electric adjustment of the backrest angle of the massage bed or massage chair, and it cannot meet the massage needs of users in different postures. Summary of the Invention

[0004] The object of the present invention is to provide an operating track structure of a massage mechanism for a convertible massage bed or chair, which is simple and reasonable in structure, easy and quick to install, safe and reliable in operation, and can perform massage both in the supine position and sitting position, aiming at the defects and deficiencies of the prior art and the above-mentioned background art.

[0005] To achieve the above object and solve the above problems, the technical solution adopted by the present invention is: a running track structure of a massage mechanism for a convertible massage bed or chair, including a frame, an electric massage mechanism, a rack, a bendable guide rail, a guide wheel frame, an angle adjustment mechanism, and a controller installed on the frame. A running gear is provided at the front end of the electric massage mechanism. The running gear is installed on the rack so that the electric massage mechanism can reciprocate. An upper guide wheel is installed at the bottom of the rear end of the electric massage mechanism. The bendable guide rail is a bendable metal strip or plastic strip and is installed below the rack. Lower guide wheels are installed on both sides of the guide wheel frame. The upper guide wheel of the electric massage mechanism is cooperatively installed with the lower guide wheels of the guide wheel frame and clamps the bendable guide rail so that it will not deviate during operation. The angle adjustment mechanism is adjusted into a massage bed mode or a massage chair mode through the controller.

[0006] The working principle and working process of the present invention: The electric massage mechanism of the present invention adopts a double-track operation to massage different parts of the human body in a lying or sitting position. A running gear is provided at the front end of the electric massage mechanism, and upper and lower guide wheels are provided at the bottom of the rear end. The running gear at the front end meshes with the rack (upper track) and can reciprocate on the track. The upper and lower guide wheels at the rear end cooperate with the bendable guide rail (lower track) to clamp and position the operation. When it is necessary to convert into a massage bed, the angle adjustment mechanism can be controlled by a mobile phone, a remote control or a controller button to adjust the backrest angle to the supine mode, and at the same time, the electric massage mechanism enters the massage bed operation mode. At this time, both the rack and the bendable guide rail are in a relatively flat state. The running gear at the front end of the electric massage mechanism meshes with the rack to convert the rotational motion of the motor into a linear motion, pushing the electric massage mechanism to move forward or backward smoothly, and at the same time driving the upper and lower guide wheels at the rear end to roll on the bendable guide rail, so that the electric massage mechanism always operates within the upper and lower tracks to massage different parts of the human body in a lying state. When it is necessary to convert into a massage chair, the angle adjustment mechanism can be controlled by a mobile phone, a remote control or a controller button to adjust the backrest angle to the seat mode, and at the same time, the electric massage mechanism enters the massage chair operation mode. At this time, the rack is in an obliquely standing state, and the bendable guide rail is in an "L"-shaped obliquely standing and bending state. The running gear at the upper end of the electric massage mechanism meshes with the rack to convert the rotational motion of the motor into a linear motion, pushing the electric massage mechanism to rise or fall smoothly, and at the same time driving the upper and lower guide wheels at the lower end to roll on the bent bendable guide rail, so that the electric massage mechanism always operates within the double tracks to massage different parts of the human body in a sitting position.

[0007] Since the present invention is provided with two running tracks, wherein the flexible guide rail can be bent and restored to be flat, and the upper guide wheel and the lower guide wheel are cooperated to enable the electric massage mechanism to run in a positioned manner. Whether in the supine mode or the seat mode, the electric massage mechanism can run safely and smoothly, realizing that the massage bed or the massage chair can adjust the backrest angle electrically without affecting the operation of the electric massage mechanism. At the same time, it has the functions of both a massage bed and a massage chair. Users can "switch" different modes arbitrarily according to their needs for massage, greatly improving the user experience, adapting to more usage scenarios, having two functions in one object and high cost performance, which is beneficial to popularization and application.

[0008] Further, side guide wheels are also installed on both sides of the guide wheel frame, and the side guide wheels are slidably connected to the inner side of the flexible guide rail in a positioned manner.

[0009] After adopting the above structure, since side guide wheels are added to the guide wheel frame of the present invention, it can further prevent the upper guide wheel and the lower guide wheel from being worn or loosened after long-term use and deviating from the track. The electric massage mechanism runs more safely and reliably on the flexible guide rail through the three pulleys of the upper guide wheel, the lower guide wheel and the side guide wheel.

[0010] Further, a limiting metal rod is welded to the rear end of the flexible guide rail, and an upper limiting beam and a lower limiting beam are provided at the rear end of the frame. The distance between the upper limiting beam and the lower limiting beam is smaller than the diameter of the limiting metal rod, and the limiting metal rod is restricted between the upper limiting beam and the lower limiting beam to prevent the flexible guide rail from slipping out when it is bent.

[0011] After adopting the above structure, since a limiting metal rod is welded to the rear end of the flexible guide rail of the present invention and an upper limiting beam and a lower limiting beam are provided at the rear end of the frame, when the massage chair is converted into a massage bed, the rear end of the flexible guide rail presses downward with the upper limiting beam and the lower limiting beam as the fulcrums. After being restored to be relatively flat, the straight-line distance between the two ends of the flexible guide rail becomes longer, and the limiting metal rod will move backward a certain distance; when the massage bed is converted into a massage chair, the rear end of the flexible guide rail bends upward with the upper limiting beam and the lower limiting beam as the fulcrums. After being bent, the straight-line distance between the two ends of the flexible guide rail becomes shorter, and the limiting metal rod will move forward a certain distance. However, since the distance between the upper limiting beam and the lower limiting beam is smaller than the diameter of the limiting metal rod, the limiting metal rod cannot break away from the restriction of the upper limiting beam and the lower limiting beam, which can prevent the flexible guide rail from slipping out and rebounding when it is bent, avoiding damage to other components and protecting the personal safety of users.

[0012] Further, the flexible guide rail is a flexible steel bar.

[0013] After adopting the above structure, the steel bar used for the flexible guide rail of the present invention is a kind of steel with good flexibility and plasticity. At the same time, the steel bar has higher strength, can still maintain a higher bearing capacity in the bent state, is not easy to break, and also has good rust prevention and corrosion resistance properties.

[0014] Furthermore, the bendable guide rail is a bendable PC (polycarbonate) strip.

[0015] After adopting the above structure, the PC (polycarbonate) strip used for the bendable guide rail material of the present invention has high strength, elastic coefficient, and high impact strength, and can withstand a large degree of bending without breaking.

[0016] Furthermore, the running track structure of the massage mechanism of a convertible massage bed or chair further includes a backrest and a seat cushion. The backrest is rotatably connected to the seat cushion and installed above the frame. Seat cushion guide rails are provided on both sides at the rear end of the frame, and seat cushion guide wheels are provided at the bottom of the seat cushion and cooperate with the seat cushion guide rails to enable the seat cushion to be slidably connected back and forth.

[0017] After adopting the above structure, since the backrest and the seat cushion of the present invention are rotatably connected, and the backrest is fixed on the frame and can be adjusted in angle. When converted into the massage chair mode, the backrest rotates upward, driving the seat cushion guide wheels of the seat cushion to move backward along the seat cushion guide rails. At this time, the straight-line distance between the farthest end of the backrest and the farthest end of the seat cushion is the shortest, and the backrest and the seat cushion form an "L" shape; when converted into the massage bed mode, the backrest rotates downward, driving the seat cushion guide wheels of the seat cushion to move forward along the seat cushion guide rails. At this time, the straight-line distance between the farthest end of the backrest and the farthest end of the seat cushion is the longest, and the backrest and the seat cushion form a "one" shape. Compared with the existing fixed seat cushion, the seat cushion of the present invention can adaptively move back and forth along the seat cushion guide rails, avoiding the formation of a gap between the backrest and the seat cushion after adjustment. A too large gap will cause insufficient support for the waist during massage, and it can prevent backache and back pain after use. Description of the Drawings

An upper guide wheel 22 is installed at the bottom of the rear end of the electric massage mechanism 2. The bendable guide rail 4 is a bendable metal strip or plastic strip and is installed below the rack 3. Lower guide wheels 51 are installed on both sides of the guide wheel frame 5. The upper guide wheel 22 of the electric massage mechanism 2 is installed in cooperation with the lower guide wheels 51 of the guide wheel frame 5 to clamp the bendable guide rail 4 so that it will not deviate during operation. The angle adjustment mechanism 6 is adjusted by the controller 7 into a massage bed mode or a massage chair mode. Since two running tracks are provided in this specific embodiment, and the bendable guide rail 4 can be bent and restored to a flat state, and in cooperation with the upper guide wheel 51 and the lower guide wheel 22, the electric massage mechanism 2 can run in a positioned manner. Whether in the supine mode or the seat mode, the electric massage mechanism 2 can run safely and smoothly, realizing that the massage bed or massage chair can adjust the backrest angle electrically without affecting the operation of the electric massage mechanism 2. At the same time, it has the functions of both a massage bed and a massage chair. Users can "switch" different modes for massage according to their needs, greatly improving the user experience, adapting to more usage scenarios, having two functions in one item, high cost performance, and being conducive to popularization and application.

[0023] Working principle and working process of this specific embodiment: The electric massage mechanism 2 of the present invention uses double-track operation to massage different parts of the human body in a lying or sitting position. A running gear 21 is provided at the front end of the electric massage mechanism 2, and an upper guide wheel 22 and a lower guide wheel 51 are provided at the bottom of the rear end. The running gear 21 at the front end meshes with the gear rack 3 (upper track) and can reciprocate on the track. The upper guide wheel 22 and the lower guide wheel 51 at the rear end cooperate with the bendable guide rail 4 (lower track) to clamp and position for operation. When it is necessary to convert it into a massage bed, the angle adjustment mechanism 6 can be controlled by a mobile phone, a remote control or a button on the controller 7 to adjust the backrest angle to the supine mode, and at the same time, the electric massage mechanism 2 enters the massage bed operation mode; at this time, both the gear rack 3 and the bendable guide rail 4 are in a relatively flat state. The running gear 21 at the front end of the electric massage mechanism 2 meshes with the gear rack 3 to convert the rotational motion of the motor into a linear motion, pushing the electric massage mechanism 2 to move forward or backward smoothly, and at the same time driving the upper guide wheel 22 and the lower guide wheel 51 at the rear end to roll in a positioned manner on the bendable guide rail 4, so that the electric massage mechanism 2 always operates within the upper and lower tracks to massage different parts of the human body in a lying state. When it is necessary to convert it into a massage chair, the angle adjustment mechanism 6 can be controlled by a mobile phone, a remote control or a button on the controller 7 to adjust the backrest angle to the seat mode, and at the same time, the electric massage mechanism 2 enters the massage chair operation mode; at this time, the gear rack 3 is in an inclined state, and the bendable guide rail 4 is in an "L"-shaped inclined and bent state. The running gear 21 at the upper end of the electric massage mechanism 2 meshes with the gear rack 3 to convert the rotational motion of the motor into a linear motion, pushing the electric massage mechanism 2 to rise or fall smoothly, and at the same time driving the upper guide wheel 22 and the lower guide wheel 51 at the lower end to roll in a positioned manner on the bent bendable guide rail 4, so that the electric massage mechanism 2 always operates within the double tracks to massage different parts of the human body in a sitting position.

The limiting metal rod 41 is restricted between the upper limiting beam 11 and the lower limiting beam 12 to prevent the bendable guide rail 4 from slipping out when it bends. Since the limiting metal rod 41 is welded to the rear end of the bendable guide rail 4 and the upper limiting beam 11 and the lower limiting beam 12 are provided at the rear end of the frame 1 in this specific embodiment, when the massage chair is converted into a massage bed, the rear end of the bendable guide rail 4 presses down with the upper limiting beam 11 and the lower limiting beam 12 as the fulcrums. After returning to a relatively flat state, the straight-line distance between the two ends of the bendable guide rail 4 becomes longer, and the limiting metal rod 41 will move backward a certain distance; when the massage bed is converted into a massage chair, the rear end of the bendable guide rail 4 bends upward with the upper limiting beam 11 and the lower limiting beam 12 as the fulcrums. After bending, the straight-line distance between the two ends of the bendable guide rail 4 becomes shorter, and the limiting metal rod 41 will move forward a certain distance. However, since the distance between the upper limiting beam 11 and the lower limiting beam 12 is smaller than the diameter of the limiting metal rod 41, the limiting metal rod 41 cannot break away from the restrictions of the upper limiting beam 11 and the lower limiting beam 12, which can prevent the bendable guide rail 4 from slipping out and rebounding when it bends, avoiding damage to other components and protecting the personal safety of users.

[0026] In this specific embodiment, the bendable guide rail 4 is a bendable steel bar. The steel bar used for the bendable guide rail 4 in this specific embodiment is a kind of steel with good flexibility and plasticity. At the same time, the steel bar has relatively high strength, can still maintain a relatively high load-bearing capacity in the bent state, is not easy to break, and also has good rust and corrosion resistance.
