Description

Technical Field

[0001] This utility model relates to the field of massage equipment technology, specifically to a massage device with a tilting guide rail, which is particularly suitable for the walking and swinging control of the massage mechanism in a massage chair, so as to achieve a massage effect that fits the curves of the human body more closely. Background Technology

[0002] With the improvement of people's living standards and the enhancement of health awareness, massage devices are becoming increasingly popular in modern life. Massage devices effectively relieve muscle fatigue and promote blood circulation by simulating the movements of human hands, thereby achieving the goal of relaxing the mind and body and improving quality of life. Traditional massage devices mostly use fixed massage heads or rollers, and their massage paths and intensities are often relatively simple, making it difficult to meet the diverse massage needs of users. To improve driving efficiency, many massage devices with mobile functions have appeared on the market. These devices, through built-in drive mechanisms, allow the massage heads or rollers to move within a certain range, thereby achieving massage of different parts of the user's body.

[0003] Existing massage mechanisms mostly use fixed guide rail structures, which cannot dynamically adjust to changes in the curves of the human body. This results in gaps between the massage mechanism and the body surface during movement, preventing precise contact and reducing the targeted nature and effectiveness of the massage. Due to insufficient contact between the massage mechanism and the body surface, the massage intensity is unevenly distributed across different parts of the body, potentially causing discomfort in some areas due to excessive pressure. Furthermore, the lower end of existing massage mechanisms is positioned relatively high during movement, easily interfering with the body and affecting the comfort and experience of the massage. Moreover, the lack of proper avoidance design when the massage mechanism passes over protruding areas such as the buttocks can easily lead to impacts, causing discomfort to the user. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a massage device with a tilting guide rail, which can better fit the curves of the human body.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A massage device with a tilting guide rail includes a frame with a guide rack and a massage mechanism that travels along the guide rack. The massage mechanism includes a drive wheel for driving the massage mechanism and a guide wheel for guiding the massage mechanism. The guide wheel and the drive wheel are spaced apart along the travel direction of the massage mechanism. The frame further includes: A tilting guide rail is configured such that the guide wheel provides a walking path to guide the massage mechanism to swing synchronously around the axis of the drive wheel during walking to conform to the curves of the human body. Viewed from the side of the frame, the guide wheel is positioned below the drive wheel, and the tilting guide rail is positioned below the guide rack to lower the lower end of the massage mechanism.

[0006] Furthermore, the massage mechanism is inclined downwards from the drive wheel to the guide wheel.

[0007] Furthermore, the drive wheel includes a traveling gear portion that engages with the guide rack and a fixed wheel portion disposed inside / outside the traveling gear portion.

[0008] Furthermore, the outer side of the guide rack is provided with a limiting groove to prevent the drive wheel from coming off the guide rack during travel, and the limiting groove is configured to cooperate with the fixed wheel.

[0009] Furthermore, the tilting guide rail is curved and configured as a groove structure.

[0010] Furthermore, the guide rack has an upwardly protruding first arc-shaped portion corresponding to the waist position of the human body.

[0011] Furthermore, the tilting guide rail has a large drop angle corresponding to the position of the human buttocks, so that when the guide wheel passes the position of the human buttocks, it can drop quickly to avoid impact with the buttocks.

[0012] Furthermore, the guide wheel is configured as a roller.

[0013] Furthermore, the massage mechanism is internally equipped with a drive device suitable for driving the walking gear section to move.

[0014] Furthermore, in the direction of movement of the massage mechanism from top to bottom, the downstream position of the guide rack is located below the downstream position of the tilting guide rail.

[0015] Due to the adoption of the above technical solutions, this utility model has the following beneficial effects: 1. This utility model provides a walking path for the guide wheel by setting a tilting guide rail, allowing the massage mechanism to swing synchronously around the axis of the drive wheel during movement. Viewed from the side of the frame, the guide wheel is positioned below the drive wheel, and the tilting guide rail is located below the guide rack. This design effectively lowers the lower end of the massage mechanism, changing the pitch angle between the drive wheel and the guide wheel. This effectively lowers the lower end of the massage mechanism, avoiding interference between the massage mechanism and the human body, further improving massage comfort, and thus allowing for a better fit between the massage mechanism and the curves of the human body. During the massage, the spatial arrangement between the massage mechanism and the human body is more rational, reducing the possibility of interference due to an excessively high lower end.

[0016] 2. This utility model's massage device with a tilting guide rail introduces a collaborative working mechanism between the tilting guide rail and the guide rack, enabling the massage mechanism to simultaneously oscillate around the axis of the drive wheel as it travels along the guide rack. This oscillation design cleverly adapts to the complex and varied curves of the human back and waist, allowing the massage mechanism to conform precisely to the body surface in real time. Whether on flat areas or raised parts, it achieves gapless contact, greatly improving the fit and precision of the massage. Thanks to the dynamic adjustment capability of the tilting guide rail, the massage mechanism can automatically adjust its posture according to changes in the body's curves during movement, ensuring that the massage intensity is evenly distributed across all parts of the body.

[0017] 3. The massage mechanism of this invention is tilted downwards in the direction from the drive wheel to the guide wheel to conform to the curves of the human body. This design allows the massage device to better adapt to the shape of the human body during movement, providing a more comfortable and ergonomic massage experience. Furthermore, the tilting guide rail has a large downward angle corresponding to the position of the buttocks. This design allows the massage device to better adapt to the curvature and shape of the buttocks during movement, reducing wear on the guide wheels during travel. Attached Figure Description

[0030] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the features in the following embodiments can be combined with each other.

[0031] like Figures 1 to 3 As shown, this utility model provides a massage device with a tilting guide rail. The massage device mainly comprises a frame 100 with a guide rack 300 and a massage mechanism 200 that travels along the guide rack. In addition to the guide rack 300, the frame 100 also has a tilting guide rail 320, which plays a crucial role in the operation of the entire massage device. The massage mechanism 200 travels along the guide rack 300 and cooperates with the tilting guide rail 320 through a drive wheel 210 and a guide wheel 220, thereby achieving a massage action that conforms to the curves of the human body. The drive wheel 210 and guide wheel 220 are arranged at intervals along the walking direction of the massage mechanism 200. Viewed from the side of the frame, the guide wheel 220 is positioned below the drive wheel 210. This arrangement provides better stability for the massage mechanism 200 during movement. For example, when the massage mechanism 200 moves along the guide rack 300, because the drive wheel 210 is above and the guide wheel 220 is below, the vertically distributed wheels can better balance the center of gravity of the massage mechanism 200 when encountering undulations or turns in the guide rack 300, reducing the possibility of swaying and deviation. Taking a real-world application scenario as an example, when the massage device is installed on a massage chair, the user sits on the massage chair, and the massage mechanism 200 begins to work. This arrangement of the drive wheel 210 and guide wheel 220 ensures that the massage mechanism 200 maintains a stable posture as it moves along the guide rack 300 from the user's buttocks to the neck, preventing the massage position from shifting or the massage intensity from being uneven due to instability. The drive wheel 210 includes a traveling gear portion 211 that meshes with the guide rack 300 and a fixed wheel portion 212 disposed outside the traveling gear portion. The tooth profile of the traveling gear portion 211 precisely matches the tooth profile of the guide rack 300 to ensure that the drive wheel 210 can travel stably on the guide rack 300. The function of the fixed wheel portion 212 is to enhance the stability of the drive wheel 210 during travel. When the fixed wheel portion 212 is disposed outside the traveling gear portion 211, it acts like a protective ring to prevent the drive wheel 210 from derailing due to external impacts during travel. At the same time, the fixed wheel portion 212 can also share some of the weight from the massage mechanism 200, making the wear of the traveling gear portion 211 more even and extending the service life of the drive wheel 210. If the fixed wheel portion 212 is disposed inside the traveling gear portion 211, it can provide a stable support structure for the traveling gear portion 211, making the traveling gear portion 211 rotate more smoothly and reducing vibration and noise caused by internal structural instability. In this embodiment, the guide wheel 220 is configured as a roller. The roller design reduces friction during movement, improving smoothness. As the guide wheel 220 moves along the tilting guide rail 320, this design significantly reduces frictional resistance, making the massage mechanism 200 move more easily and flexibly. Furthermore, the roller's structural design allows it to roll freely within the tilting guide rail 320, adapting to various shape changes and maintaining good operational performance regardless of whether the section is straight or curved. like Figures 4 to 6 As shown, in this embodiment, the massage mechanism 200 is tilted downwards from the drive wheel 210 to the guide wheel 220. This tilting design is closely related to the cooperation between the tilting guide rail 320 and the guide rack 300. Since the tilting guide rail 320 is located below the guide rack 300, when the guide wheel 220 moves along the tilting guide rail 320, it gradually lifts the upper part of the massage mechanism 200, thus making the massage mechanism 200 tilt downwards as a whole. This tilting state can better conform to the curve of the human back. Taking a sitting posture as an example, the human back has a certain curvature from the shoulders to the buttocks. The downward tilting state of the massage mechanism 200 can make the massage head or massage components maintain a more suitable contact angle and pressure with various parts of the human back, improving the comfort and effect of the massage. For example, when massaging the human waist, the tilting state of the massage mechanism 200 allows the massage head to apply massage force at an angle closer to the curve of the human waist, deeply massaging the muscle tissue of the waist and relieving waist fatigue. The massage mechanism 200 is internally equipped with a drive device 230 suitable for driving the walking gear section 211. This drive device can take various forms, such as motor drive. The motor is connected to the walking gear section 211 via a transmission mechanism, converting electrical energy into mechanical energy to drive the walking gear section 211 to rotate on the guide rack 300. The transmission mechanism can be gear drive, chain drive, or belt drive, etc. Taking gear drive as an example, the output shaft of the motor is connected to a driving gear, which meshes with the driven gear on the walking gear section 211. Through the meshing transmission between the gears, the rotational motion of the motor is transmitted to the walking gear section 211. This transmission method has the advantages of high transmission efficiency and high precision, and can accurately control the speed and direction of rotation of the walking gear section 211, thereby achieving precise movement of the massage mechanism 200 on the guide rack 300. The drive device can also be equipped with a control system, which monitors the position and operating status of the massage mechanism 200 in real time through sensors, and adjusts the output power and speed of the drive device according to preset programs and user operation commands, realizing intelligent control of the massage device. The guide rack 300 has a first arc-shaped portion 301 that protrudes upwards at the waist position, located downstream of the guide rack 300. The first arc-shaped portion 301 is designed to conform to the curve of the human body, enhancing the massage effect. When the massage mechanism 200 moves to the waist position, due to the upward protrusion of the first arc-shaped portion 301, the massage mechanism 200 rises along with the shape change of the guide rack 300, allowing the massage components to better conform to the curve of the waist and increase the massage intensity. For example, during the massage, the massage heads on the massage mechanism 200 can press deeper into the erector spinae muscles on both sides of the waist, effectively relieving tension in the waist muscles. The guide rack 300 also includes a second arc-shaped portion 302 that protrudes upwards at the neck position, located upstream of the guide rack 300. When the massage mechanism 200 moves to the neck area, the upward protrusion of the second arc-shaped portion 302 allows the massage components to more accurately target the neck muscles and acupoints, such as Fengchi and Tianzhu acupoints. Massaging these acupoints improves neck blood circulation and relieves neck fatigue and pain. The design of the second arc-shaped portion 302 is also to conform to the curve of the human body, working in conjunction with the first arc-shaped portion 301 to further enhance the massage effect. When the massage mechanism 200 moves from upstream to downstream of the guide rack 300, it first passes through the second arc-shaped portion 302. During this process, the massage mechanism 200 gradually rises along the shape of the second arc-shaped portion 302, allowing the massage components to better adapt to the curve of the human neck.

[0032] The outer side of the guide rack is equipped with a limiting groove 310 to prevent the drive wheel from dislodging from the guide rack during movement. The limiting groove 310 is configured to cooperate with the fixed wheel portion 212. The shape and size of the limiting groove 310 are precisely matched with the fixed wheel portion 212, so that when the drive wheel 210 moves on the guide rack 300, the fixed wheel portion 212 always runs within the limiting groove 310. This effectively prevents the drive wheel 210 from derailing due to external impact or deviation during operation. For example, during the operation of the massage device, some external forces may be generated due to sudden movements of the user or vibrations of the massage mechanism 200. The cooperation between the limiting groove 310 and the fixed wheel portion 212 ensures that the drive wheel 210 always runs stably on the guide rack 300, guaranteeing the normal operation of the massage device. The limiting groove 310 can also fine-tune the running trajectory of the drive wheel 210. When the drive wheel 210 deviates slightly, the inner wall of the limiting groove 310 will exert a certain force on the fixed wheel part 212, so that it returns to the correct running trajectory, thereby improving the stability and reliability of the massage device. In this embodiment, the tilting guide rail 320 is curved and configured as a groove structure. The tilting guide rail 320 is an overall inclined L-shaped track structure, including a vertically inclined slanted groove 321 and a basically horizontally arranged transverse groove 322. The connection between the slanted groove 321 and the transverse groove 322 is a curved groove, a design that allows the guide wheel 220 to transition more smoothly during movement. The slanted groove 321 is an arc-shaped groove designed according to the curvature of the human back, with its tilt angle and curvature matching the human back. When the massage mechanism 200 moves along the guide rack 300, the guide wheel 220 travels within the slanted groove 321. Because the shape of the slanted groove 321 is similar to the curve of the human back, the massage mechanism 200 can better conform to the human back. For example, during massage, the massage components on the massage mechanism 200 can more evenly contact various parts of the human back, providing appropriate massage intensity from the shoulders to the waist. The transverse groove 322 is used to limit the range of movement of the massage mechanism 200 and prevent it from moving excessively. When the massage mechanism 200 moves to a certain position, the guide wheel 220 will enter the transverse groove 322. At this time, the direction of movement of the massage mechanism 200 will be limited by the transverse groove 322 to avoid damage to the massage device or discomfort to the user due to excessive movement. The tilting guide rail 320 has a large downward angle corresponding to the buttocks, allowing the guide roller 220 to quickly descend and avoid impact when passing over the buttocks. When the massage mechanism 200 moves from the waist to the buttocks, the guide roller 220 enters the section of the tilting guide rail 320 corresponding to the buttocks. Due to the large downward angle of this section, the guide roller 220 descends rapidly, causing the entire massage mechanism 200 to descend. This effectively prevents the massage mechanism 200 from impacting the buttocks when passing over them, protecting the user's safety and comfort. For example, in actual use, when a user sits on a massage chair, as the massage mechanism 200 moves to the buttocks position, due to this special design of the tilting guide rail 320, the massage mechanism 200 can descend smoothly, passing over the buttocks without causing any discomfort or injury. The tilting guide rail 320 is also configured to drive the massage mechanism 200 to oscillate around the axis of the drive wheel 210. As the guide wheel 220 moves within the tilting guide rail 320, its position changes due to the shape change of the tilting guide rail 320, causing the massage mechanism 200 to oscillate around the axis of the drive wheel 210. This oscillation allows the massage mechanism 200 to better conform to the curves of the human body. For example, when the massage mechanism 200 moves to the curved part of the human back, the shape of the tilting guide rail 320 causes the guide wheel 220 to move to one side, thus causing the massage mechanism 200 to oscillate around the axis of the drive wheel 210. This allows the massage components to contact the curved part of the human back at a more suitable angle and with greater force, improving the massage effect. When massaging the muscles on both sides of the spine, the oscillation of the massage mechanism 200 allows the massage head to more comprehensively cover the muscle area, achieving a more effective massage.

[0033] In the downward movement direction of the massage mechanism 200, the downstream position of the guide rack 300 is located below the downstream position of the tilting guide rail 320. This design ensures that when the massage mechanism 200 moves to its lowest position, the guide wheel 220 remains supported and guided within the tilting guide rail 320. For example, when the massage mechanism 200 moves to the lowest point of the massage device, corresponding to below the buttocks, although the guide rack 300 has reached its end, the tilting guide rail 320 continues to extend for a distance. This ensures that the massage mechanism 200 remains stable throughout its operation and does not lose support and guidance due to the end of the guide rack 300, guaranteeing the safety and reliability of the massage device. Simultaneously, this length design of the tilting guide rail 320 also facilitates the return stroke of the massage mechanism 200. During the return stroke, the guide wheel 220 can smoothly return from the tilting guide rail 320 to its normal operating track, realizing the reciprocating motion of the massage mechanism 200.
