Description

Technical Field

[0001] This utility model relates to the field of massage equipment technology, specifically to a massage mechanism track structure that can be converted into a massage bed or chair. Background Technology

[0002] Massage beds and massage chairs are common equipment in homes, physiotherapy centers, and beauty salons, used to relax muscles, relieve fatigue, or assist in professional massage. Massage chairs primarily utilize mechanical rolling and squeezing forces for massage, incorporating various massage mechanisms such as massage rollers, airbags, and vibration motors. The massage rollers, through up-and-down and left-and-right movement, mimic the kneading and pushing motions of human hands, massaging areas like the back and waist. Airbags, through inflation and deflation, compress and envelop various parts of the body, simulating manual pressure. The vibrations generated by the vibration motor relax muscles. Through the coordinated work of these massage mechanisms, massage chairs can provide comprehensive massage to different parts of the body, promoting blood circulation and relieving muscle fatigue. Massage beds, as an important piece of equipment in massage therapy, provide users with a comfortable and stable massage experience platform. They are mainly used in beauty salons, physiotherapy centers, massage parlors, and homes, not only assisting massage therapists in professional operations but also allowing users to enjoy the benefits of massage in a relaxed state.

[0003] Due to significant differences in function, structure, and usage scenarios between massage beds and massage chairs, directly "converting" them (i.e., turning a massage bed into a massage chair or vice versa) is technically difficult. Currently, some massage beds or chairs on the market have electrically adjustable backrests, allowing users to recline or sit in a seated position, but these adjustments do not provide automatic massage functionality. This is because it is not yet possible to electrically adjust the backrest angle of a massage bed or chair without affecting the operation of the electric massage mechanism, thus failing to meet the massage needs of users in different postures. Summary of the Invention

[0004] The purpose of this utility model is to address the deficiencies and shortcomings of the existing technology and the aforementioned background technology by providing a massage mechanism operating track structure that can be converted into a massage bed or chair. The structure is simple and reasonable, easy and quick to install, and safe and reliable to operate, allowing for both lying down and sitting massage.

[0005] To achieve the above objectives and solve the above problems, the technical solution adopted by this utility model is: a massage mechanism running track structure for a convertible massage bed or chair, including a frame and an electric massage mechanism, a gear rack, a flexible guide rail, a guide wheel frame, an angle adjustment mechanism, and a controller mounted on the frame. The electric massage mechanism has a running gear at its front end, which is mounted on the gear rack to enable the electric massage mechanism to reciprocate. An upper guide wheel is mounted at the bottom of the rear end of the electric massage mechanism. The flexible guide rail is a flexible metal or plastic strip mounted below the gear rack. Lower guide wheels are mounted on both sides of the guide wheel frame. The upper guide wheel of the electric massage mechanism, through the cooperation of the lower guide wheels of the guide wheel frame, clamps the flexible guide rail to prevent it from deviating during operation. The angle adjustment mechanism is adjusted to massage bed mode or massage chair mode by the controller.

[0006] The working principle and workflow of this utility model are as follows: The electric massage mechanism of this utility model uses a dual-track operation to massage different parts of the human body in a lying or sitting position. The front end of the electric massage mechanism is equipped with a running gear, and the rear end has upper and lower guide wheels. The front running gear meshes with the gear rack (upper track) and can reciprocate on the track. The rear upper and lower guide wheels cooperate with the flexible guide rail (lower track) for clamping and positioning. When it needs to be converted into a massage bed, the backrest angle can be adjusted to a reclining mode using a mobile phone, remote control, or controller button. At the same time, the electric massage mechanism enters the massage bed operation mode. In this state, the gear rack and flexible guide rail are relatively flat. The meshing of the front running gear and gear rack converts the rotational motion of the motor into linear motion, propelling the electric massage mechanism forward or backward smoothly. Simultaneously, it drives the rear upper and lower guide wheels to roll and position on the flexible guide rail, ensuring that the electric massage mechanism always operates within the upper and lower tracks, massaging different parts of the human body in a lying position. When it needs to be converted into a massage chair, the backrest angle can be adjusted to seat mode via mobile phone, remote control, or controller buttons. At the same time, the electric massage mechanism enters the massage chair operation mode. In this state, the gear rack is in an inclined position, and the flexible guide rail is in an "L"-shaped inclined and bent position. The running gear at the upper end of the electric massage mechanism meshes with the gear rack to convert the rotational motion of the motor into linear motion, pushing the electric massage mechanism to rise or fall smoothly. At the same time, it drives the upper and lower guide wheels at the lower end to roll and position on the bent flexible guide rail, so that the electric massage mechanism always runs within the dual track, massaging different parts of the human body in a seated position.

[0007] Because this utility model is equipped with two running tracks, one of which is a flexible guide rail that can bend and return to flatness, it works in conjunction with the upper and lower guide wheels to position and operate the electric massage mechanism. Whether in reclining mode or seat mode, the electric massage mechanism can operate safely and smoothly. This allows the massage bed or massage chair to adjust the backrest angle electrically without affecting the operation of the electric massage mechanism. It simultaneously functions as a massage bed and a massage chair, allowing users to freely "switch" between different modes for massage according to their needs, greatly improving the user experience and adapting to more usage scenarios. It is a dual-purpose product with high cost-effectiveness, which is conducive to its widespread application.

[0008] Furthermore, 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.

[0009] With the above structure, the addition of side guide wheels to the guide wheel frame of this utility model can further prevent the upper and lower guide wheels from wearing out or loosening and deviating from the track after long-term use. The electric massage mechanism is positioned and runs on the flexible guide rail by the three pulleys of the upper guide wheel, lower guide wheel and side guide wheel, making it safer and more reliable.

[0010] Furthermore, 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 less than the diameter of the limiting metal rod. The limiting metal rod is confined between the upper limiting beam and the lower limiting beam to prevent the flexible guide rail from coming off when it bends.

[0011] With the above structure, since the flexible guide rail of this utility model has a limiting metal rod welded to its rear end, and the frame has an upper limit beam and a lower limit beam at its rear end, when the massage chair is converted into a massage bed, the rear end of the flexible guide rail is pressed downward with the upper limit beam and the lower limit beam as fulcrums. After the flexible guide rail returns to a relatively flat state, the straight-line distance between the two ends 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 limit beam and the lower limit beam as fulcrums. After the flexible guide rail bends, the straight-line distance between the two ends becomes shorter, and the limiting metal rod will move forward a certain distance. However, since the distance between the upper limit beam and the lower limit beam is less than the diameter of the limiting metal rod, the limiting metal rod cannot break free from the restriction of the upper limit beam and the lower limit beam. This can prevent the flexible guide rail from detaching and rebounding when bending, avoiding damage to other components and protecting the user's personal safety.

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

[0013] With the above structure, the steel strip used in the flexible guide rail of this utility model is a steel with good flexibility and plasticity. At the same time, the steel strip has high strength and can still maintain high load-bearing capacity in the bending state. It is not easy to break and also has good rust prevention and corrosion resistance.

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

[0015] With the above structure, the PC (polycarbonate) strip used in the flexible guide rail of this utility model has high strength and elasticity coefficient, high impact strength, and can withstand a large degree of bending without breaking.

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

[0017] With the above structure, since the backrest and seat cushion of this invention are rotatably connected, and the backrest is fixed to the frame and its angle is adjustable, when converted to massage chair mode, the backrest rotates upward, causing the seat cushion guide rollers to move backward along the seat cushion guide rail. At this time, the straight-line distance between the farthest point of the backrest and the farthest point of the seat cushion is the shortest, and the backrest and seat cushion form an "L" shape. When converted to massage bed mode, the backrest rotates downward, causing the seat cushion guide rollers to move forward along the seat cushion guide rail. At this time, the straight-line distance between the farthest point of the backrest and the farthest point of the seat cushion is the longest, and the backrest and seat cushion form a "I" shape. Compared with existing fixed seat cushions, the seat cushion of this invention can adaptively move back and forth along the seat cushion guide rail, avoiding gaps between the backrest and the seat cushion after adjustment. Excessive gaps can prevent sufficient support for the lower back during massage, thus preventing back pain after use. Attached Figure Description

[0032] The present invention will be further described below with reference to the accompanying drawings.

[0033] See Figures 1-3 As shown, the technical solution adopted in this specific embodiment is:

[0034] A massage mechanism running track structure for a convertible massage bed or chair includes a frame 1 and an electric massage mechanism 2, a gear rack 3, a flexible guide rail 4, a guide wheel frame 5, an angle adjustment mechanism 6, and a controller 7 mounted on the frame 1. The electric massage mechanism 2 has a running gear 21 at its front end, which is mounted on the gear rack 3 to enable the electric massage mechanism 2 to reciprocate. An upper guide wheel 22 is mounted at the bottom of the rear end of the electric massage mechanism 2. The flexible guide rail 4 is a flexible metal or plastic strip mounted below the gear rack 3. Lower guide wheels 51 are mounted on both sides of the guide wheel frame 5. The upper guide wheel 22 of the electric massage mechanism 2, through the cooperation of the lower guide wheels 51 of the guide wheel frame 5, clamps the flexible guide rail 4 to prevent it from deviating during operation. The angle adjustment mechanism 6 is adjusted to massage bed mode or massage chair mode by the controller 7. Because this specific embodiment is equipped with two running tracks, the flexible guide rail 4 can bend and return to flatness. Together with the upper guide wheel 51 and the lower guide wheel 22, the electric massage mechanism 2 is positioned and operated. Whether in reclining mode or seat mode, the electric massage mechanism 2 can operate safely and smoothly. This allows the massage bed or massage chair to adjust the backrest angle electrically without affecting the operation of the electric massage mechanism 2. It has the functions of both a massage bed and a massage chair. Users can "switch" between different modes for massage according to their needs, greatly improving the user experience and adapting to more usage scenarios. It is a dual-purpose product with high cost performance, which is conducive to its widespread application.

[0035] The working principle and workflow of this specific embodiment: The electric massage mechanism 2 of this utility model adopts a dual-track operation to massage different parts of the human body in a lying or sitting position. The front end of the electric massage mechanism 2 is provided with a running gear 21, and the rear end bottom is provided with an upper guide wheel 22 and a lower guide wheel 51. 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 flexible guide rail 4 (lower track) to clamp and position the operation. When it needs to be converted into a massage bed, the angle adjustment mechanism 6 can be controlled via mobile phone, remote control, or button 7 of the controller to adjust the backrest angle to the reclining mode. At the same time, the electric massage mechanism 2 enters the massage bed operation mode. At this time, the gear rack 3 and the flexible 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 linear motion, pushing the electric massage mechanism 2 to move forward or backward smoothly. At the same time, it drives the upper guide wheel 22 and the lower guide wheel 51 at the rear end to roll and position on the flexible guide rail 4, so that the electric massage mechanism 2 always runs within the upper and lower rails to massage different parts of the body in the reclining state. When it needs to be converted into a massage chair, the angle adjustment mechanism 6 can be controlled via mobile phone, remote control, or button 7 of the controller to adjust the backrest angle to the seat mode. 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 flexible 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 linear motion, which pushes the electric massage mechanism 2 to rise or fall smoothly. At the same time, it drives the upper guide wheel 22 and the lower guide wheel 51 at the lower end to roll and position on the bent flexible guide rail 4, so that the electric massage mechanism 2 always runs within the double track to massage different parts of the human body in a seated position.

[0036] In this specific embodiment, side guide wheels 52 are also installed on both sides of the guide wheel frame 5. The side guide wheels 52 are slidably connected to the inner side of the flexible guide rail 4. Because side guide wheels are added to the guide wheel frame in this specific embodiment, it can further prevent the upper and lower guide wheels from wearing out or loosening and deviating from the track after prolonged use. The electric massage mechanism operates more safely and reliably on the flexible guide rail through the positioning of the upper guide wheel, lower guide wheel, and side guide wheels.

[0037] In this specific embodiment, a limiting metal rod 41 is welded to the rear end of the flexible guide rail 4, and an upper limiting beam 11 and a lower limiting beam 12 are provided at the rear end of the frame 1. The distance between the upper limiting beam 11 and the lower limiting beam 12 is less than the diameter of the limiting metal rod. The limiting metal rod 41 is restricted between the upper limiting beam 11 and the lower limiting beam 12 to prevent the flexible guide rail 4 from coming off when it bends. Because the flexible guide rail 4 in this specific embodiment has a limiting metal rod 41 welded to its rear end, and the frame 1 has an upper limit beam 11 and a lower limit beam 12 at its rear end, when the massage chair is converted into a massage bed, the rear end of the flexible guide rail 4 is pressed downward with the upper limit beam 11 and the lower limit beam 12 as fulcrums. After returning to a relatively flat state, the straight-line distance between the two ends of the flexible 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 flexible guide rail 4 bends upward with the upper limit beam 11 and the lower limit beam 12 as fulcrums. After bending, the straight-line distance between the two ends of the flexible guide rail 4 becomes shorter, and the limiting metal rod 41 will move forward a certain distance. However, since the distance between the upper limit beam 11 and the lower limit beam 12 is less than the diameter of the limiting metal rod 41, the limiting metal rod 41 cannot break free from the restriction of the upper limit beam 11 and the lower limit beam 12. This can prevent the flexible guide rail 4 from detaching and rebounding when bending, avoiding damage to other components and protecting the user's personal safety.

[0038] In this specific embodiment, the flexible guide rail 4 is a flexible steel strip. The flexible guide rail 4 in this specific embodiment uses a steel strip with good flexibility and plasticity. At the same time, the steel strip has high strength, can maintain a high load-bearing capacity in a bent state, is not easy to break, and also has good rust and corrosion resistance.

[0039] In this specific embodiment, the flexible guide rail 4 can also be made of flexible PC (polycarbonate) strips. The PC (polycarbonate) strips used in the flexible guide rail 4 of this specific embodiment have high strength and elasticity, high impact strength, and can withstand a large degree of bending without breaking.

[0040] See Figure 4As shown, the massage mechanism running track structure of the convertible massage bed or chair includes a backrest and a seat cushion 8. The backrest and seat cushion 8 are rotatably connected and mounted on top of the frame 1. Seat cushion guide rails 13 are provided on both sides of the rear end of the frame 1. Seat cushion guide wheels 81 are provided at the bottom of the seat cushion 8, which cooperate with the seat cushion guide rails 13 to allow the seat cushion 8 to slide back and forth. Since the backrest and seat cushion 8 are rotatably connected in this specific embodiment, and the backrest is fixed to the frame 1 and the angle is adjustable, when converted to massage chair mode, the backrest rotates upward, driving the seat cushion guide wheels 81 of the seat cushion 8 to move backward along the seat cushion guide rails 13. At this time, the straight-line distance between the farthest end of the backrest and the farthest end of the seat cushion 8 is the shortest, and the backrest and seat cushion 8 form an "L" shape. When converted to massage bed mode, the backrest rotates downward, driving the seat cushion guide wheels 81 of the seat cushion 8 to move forward along the seat cushion guide rails 13. At this time, the straight-line distance between the farthest end of the backrest and the farthest end of the seat cushion 8 is the longest, and the backrest and seat cushion 8 form a "I" shape. Compared with existing fixed seat cushions, the seat cushion 8 of this invention can adaptively move back and forth along the seat cushion guide rail 13, avoiding the formation of a gap between the backrest and the seat cushion 8. If the gap is too large, it will not provide enough support for the waist during massage, thus preventing back pain after use.

[0041] This utility model has a scientific and reasonable structure, simple and efficient assembly, and safe and reliable limit operation. It can be used for massage while lying down or sitting, making it suitable for different usage scenarios. It provides a good user experience, is cost-effective with two uses, and has low production costs, which is conducive to its widespread application.
