Detailed implementation manners

[0026] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some but not all of the embodiments of the present application. The components of the embodiments of the present application described and illustrated herein generally can be arranged and designed in a variety of different configurations.

[0027] Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the present application claimed, but merely represents selected embodiments of the present application. It should be noted that, without conflict, the various features in the embodiments of the present application can be combined with each other, and the combined embodiments are still within the protection scope of the present application.

[0028] It should be noted that: like reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0029] In the description of the present application, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the product of this application is usually placed during use. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present application. In addition, the terms "first", "second", "third", etc. are only used for descriptive distinction and cannot be understood as indicating or implying relative importance.

[0030] In addition, terms such as "horizontal" and "vertical" do not require the components to be absolutely horizontal or hanging vertically, but can be slightly inclined. For example, "horizontal" only means that its direction is more horizontal relative to "vertical", and does not mean that the structure must be completely horizontal, but can be slightly inclined.

[0031] In the description of the present application, it should also be noted that unless otherwise clearly specified and limited, the terms "set", "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0032] On the one hand of the embodiments of the present application, a handrail structure is provided, as Figures 1 to 6 shown, including a first handrail assembly 3, a second handrail assembly 2 connected to the first handrail assembly 3, and a driving assembly drivingly connected to the second handrail assembly 2. A first guide rail 3-1 is installed on the first handrail assembly 3, a guiding member 2-1 is installed on the second handrail assembly 2, the guiding member 2-1 is slidably arranged on the first guide rail 3-1, and the driving assembly drives the second handrail assembly 2 to move up and down relative to the first handrail assembly 3 along the length direction of the first guide rail 3-1.

[0033] Specifically, by using the first handrail assembly 3 as the basic component, firm support and guidance are provided, and the driving assembly is drivingly connected to the second handrail assembly 2, so that the driving assembly can control the up and down movement of the second handrail assembly 2, thereby realizing the adjustment of the height of the handrail structure, facilitating consumers to enter the massage chair, and at the same time, the height of the arm massage assembly can also be adjusted, achieving the effect of stretching and massaging the user's arm, so that the handrail structure meets the needs of different heights and usage scenarios. In addition, by installing the first guide rail 3-1 on the first handrail assembly 3, the first guide rail 3-1 can provide a stable and smooth sliding path, and the guiding member 2-1 is installed on the second handrail assembly 2, and the guiding member 2-1 is slidably arranged on the first guide rail 3-1, so that the guiding member 2-1 can slide smoothly in the first guide rail 3-1, thereby ensuring that the second handrail assembly 2 can move up and down along the length direction of the first guide rail 3-1 under the drive of the driving assembly, effectively preventing the relative offset between the handrail assemblies, and ensuring the smoothness and accuracy during the height adjustment of the handrail structure.

[0034] It should be noted that the first guide rail 3-1 can be installed on both sides of the first armrest assembly 3 simultaneously. Correspondingly, the guiding member 2-1 is also symmetrically installed on both sides of the second armrest assembly 2. Such a design can provide more stable support and more uniform force transmission, enabling the second armrest assembly 2 to be evenly supported by the first guide rails 3-1 on both sides during the lifting process, which helps to reduce torsion and unstable factors during movement and enhances the overall stability of the structure. The first guide rail 3-1 can also be installed only at the middle position of the first armrest assembly 3, simplifying the structural design, reducing material and manufacturing costs, and at the same time enabling precise lifting function within a limited space. Among them, the first guide rail 3-1 and the guiding member 2-1 can be designed as profiles to achieve smooth sliding of the guiding member 2-1 within the first guide rail 3-1. In addition, a second gear can be provided on the first armrest assembly 3 and a second rack can be provided on the second armrest assembly 2, and the second gear and the second rack are engaged to drive, so as to replace the first guide rail 3-1 and the guiding member 2-1 to achieve precise height adjustment of the second armrest assembly 2 relative to the first armrest assembly 3.

[0035] Optionally, the drive assembly includes a drive source 4 and a telescopic rod member 5 that is drivingly connected to the drive source 4. The telescopic rod member 5 is connected to the second armrest assembly 2, and the drive source 4 drives the second armrest assembly 2 to move through the telescopic rod member 5.

[0036] Specifically, as Figure 2 shown, the drive assembly includes a drive source 4 and a telescopic rod member 5 that is drivingly connected to the drive source 4. The drive source 4 is fixed on the first armrest assembly 3 to provide stable driving force for the telescopic rod member 5. The design of the driving force should consider the matching of power and speed to ensure that the second armrest assembly 2 is both efficient and safe during the lifting process. The drive source 4 is connected to the second armrest assembly 2 through the telescopic rod member 5. Among them, the telescopic rod member 5 has a fixed end and a telescopic end. The fixed end is connected to the output shaft of the drive source 4, and the telescopic end is connected to the second armrest assembly 2, so that the movement of the drive source 4 can be directly transmitted to the second armrest assembly 2, thereby realizing the lifting movement of the second armrest assembly 2 relative to the first armrest assembly 3 along the length direction of the first guide rail 3-1. Among them, the drive source 4 can be a motor, a hydraulic system or other suitable drive source 4, and the telescopic rod member 5 can be a lead screw, an electric push rod or other types of telescopic rod members 5. Select a suitable drive source 4 and type of telescopic rod member 5 according to the application scenario and performance requirements to ensure the stability and precision of the movement of the second armrest assembly 2.

[0037] Optionally, the driving component includes a driving source 4, a first rotating member 4-1, a straight rod 6-2 and a bent rod 6-3. The driving source 4 is drivingly connected to the first rotating member 4-1. A first sliding rail 2-2 perpendicular to the first guide rail 3-1 is installed on the second armrest assembly 2. One end of the straight rod 6-2 is threadedly sleeved on the first rotating member 4-1. The other end of the straight rod 6-2 is hinged to one end of the bent rod 6-3. The other end of the bent rod 6-3 is slidably disposed on the first sliding rail 2-2. The bent portion of the bent rod 6-3 is hinged to the first armrest assembly 3.

[0038] Specifically, as Figure 3 shown, both ends of the first rotating member 4-1 are fixed to the first armrest assembly 3 through bearings, ensuring that it can rotate stably under the drive of the driving source 4 without excessive friction and vibration. In the embodiment of the present application, the first rotating member 4-1 is a lead screw, and a slider 6-1 is threadedly sleeved on the first rotating member 4-1. Thus, when the first rotating member 4-1 starts to rotate, the threaded sleeving method can convert the rotational motion of the first rotating member 4-1 into the linear motion of the slider 6-1, enabling the slider 6-1 to slide along the axial direction of the first rotating member 4-1. One end of the straight rod 6-2 is hinged to the slider 6-1. Therefore, when the slider 6-1 slides along the first rotating member 4-1, one end of the straight rod 6-2 will also slide synchronously in the same direction. This connection ensures that the linear motion of the slider 6-1 can be effectively transmitted to the straight rod 6-2 without problems of failure or unstable sliding. The other end of the straight rod 6-2 is hinged to one end of the bent rod 6-3, and the bent portion of the bent rod 6-3 is hinged to the first armrest assembly 3 through screws, and its position remains unchanged. When the straight rod 6-2 slides, the position of the hinge point between the straight rod 6-2 and the bent rod 6-3 will change, which means that the motion of the straight rod 6-2 causes the bent rod 6-3 to swing around its bent portion. At this time, by installing a first sliding rail 2-2 perpendicular to the first guide rail 3-1 on the second armrest assembly 2, the other end of the bent rod 6-3 is slidably disposed on the first sliding rail 2-2 through bearings. Therefore, when the bent rod 6-3 swings around its bent portion, its other end can only slide inside the first sliding rail 2-2. Thus, the swing of the bent rod 6-3 drives the second armrest assembly 2 to perform a smooth lifting and lowering motion relative to the first armrest assembly 3 along the length direction of the first guide rail 3-1.

[0039] Generally speaking, through the complex coordinated motion of the straight rod 6-2 and the bent rod 6-3 in the whole motion process, the rotational motion of the first rotating member 4-1 is effectively converted into the lifting and lowering motion of the second armrest assembly 2 along the first guide rail 3-1. This design not only ensures the stability and reliability of the structure but also can provide precise lifting control.

[0040] Optionally, the driving assembly includes a driving source 4, a second rotating member 4-2, a first gear 7-1, and a first rack 7-2. The driving source 4 is drivingly connected to the first gear 7-1 via the second rotating member 4-2. The first rack 7-2 meshes with the first gear 7-1. One end of the first rack 7-2 away from the first gear 7-1 is fixedly connected to the second armrest assembly 2. The length direction of the first rack 7-2 is parallel to the length direction of the first guide rail 3-1.

[0041] Specifically, as Figure 4 shown, both ends of the second rotating member 4-2 are fixed to the first armrest assembly 3 through bearings, ensuring that it can rotate stably under the drive of the driving source 4 without excessive friction and vibration. In the embodiment of the present application, the second rotating member 4-2 is a roller, and the first gear 7-1 is fixedly sleeved on the second rotating member 4-2. When the driving source 4 is started, the second rotating member 4-2 transmits the rotational motion of the driving source 4 to the first gear 7-1, enabling the first gear 7-1 to rotate stably and efficiently. The first gear 7-1 meshes with the first rack 7-2, and the length direction of the first rack 7-2 is parallel to the length direction of the first guide rail 3-1, ensuring that it can cooperate with the first gear 7-1 smoothly. The rotational motion of the first gear 7-1 is converted into a linear motion through the first rack 7-2 meshing with it, and the other end of the first rack 7-2 is fixedly connected to the second armrest assembly 2, thereby being able to drive the second armrest assembly 2 to move up and down along the first guide rail 3-1. Such a driving mechanism realizes the high efficiency and reliability of height adjustment, avoiding the unstable sliding and jamming phenomena in traditional mechanical systems.

[0042] Optionally, the driving assembly includes a driving source 4, a second rotating member 4-2, a pulley assembly 8-1, and a transmission rope 8-2. The driving source 4 is drivingly connected to the pulley assembly 8-1 via the second rotating member 4-2. The transmission rope 8-2 is wound around the pulley assembly 8-1, and the transmission rope 8-2 is fixedly connected to the second armrest assembly 2. The driving source 4 drives the pulley assembly 8-1 to rotate via the second rotating member 4-2 to drive the transmission rope 8-2 to rotate around the pulley assembly 8-1.

[0043] Specifically, as Figure 5As shown, the pulley assembly 8-1 includes multiple pulleys that can be fixed at different positions. One of the pulleys needs to be fixedly sleeved on the second rotating member 4-2 to effectively transmit the rotational motion of the drive source 4 to the pulley assembly 8-1 through the second rotating member 4-2 and guide the path of the transmission rope 8-2. The transmission rope 8-2 is wound around the pulley assembly 8-1 to ensure that the transmission rope 8-2 can move smoothly along the pulley path. One end of the transmission rope 8-2 is fixedly connected to the second armrest assembly 2, so that the movement of the transmission rope 8-2 will directly affect the height change of the second armrest assembly 2. When the drive source 4 is started, the pulley assembly 8-1 is driven to rotate by the second rotating member 4-2. The rotation of the pulley assembly 8-1 will cause the transmission rope 8-2 to wind along the pulley path, so that by pulling or releasing the transmission rope 8-2, the second armrest assembly 2 can slide along the length direction of the first guide rail 3-1. In this way, the adjustment of the armrest height becomes more flexible and smooth. It should be noted that the pulley assembly 8-1 can also be replaced by a sprocket assembly. Correspondingly, the transmission rope 8-2 should be replaced by a chain that meshes with it.

[0044] Optionally, the drive assembly includes a drive source 4, a second rotating member 4-2, an eccentric wheel 9-1, and a transmission rod 9-2. The drive source 4 is drivingly connected to the eccentric wheel 9-1 through the second rotating member 4-2. The transmission rod 9-2 abuts against the eccentric wheel 9-1, and the end of the transmission rod 9-2 away from the eccentric wheel 9-1 is fixedly connected to the second armrest assembly 2.

[0045] Specifically, as Figure 6 shown, the eccentric wheel 9-1 is fixedly sleeved on the second rotating member 4-2 to effectively transmit the rotational motion of the drive source 4 to the eccentric wheel 9-1 through the second rotating member 4-2, so that the eccentric wheel 9-1 can rotate stably and efficiently. The eccentric wheel 9-1, that is, a cam, has an eccentric rotating shaft, so that when the eccentric wheel 9-1 rotates, the transmission rod 9-2 abutting against one end of the eccentric wheel 9-1 can generate a reciprocating linear motion, and the other end of the transmission rod 9-2 is fixedly connected to the second armrest assembly 2, ensuring that the linear motion of the transmission rod 9-2 directly affects the height change of the second armrest assembly 2. When the drive source 4 is started, the eccentric wheel 9-1 is driven to rotate by the second rotating member 4-2, and the rotational motion of the eccentric wheel 9-1 is then converted into a linear motion through the transmission rod 9-2, thereby pushing the second armrest assembly 2 to slide along the length direction of the first guide rail 3-1.

[0046] Optionally, as Figure 6 shown, in order to enhance the stability and accuracy of the system, a second guide rail 2-3 parallel to the first guide rail 3-1 is installed on the first armrest assembly 3 or the second armrest assembly 2. The transmission rod 9-2 is slidably disposed in the second guide rail 2-3 to ensure that the movement of the transmission rod 9-2 is smoother and more accurate, and to avoid possible offset and instability problems during the movement of the transmission rod 9-2.

[0047] Optionally, the drive assembly further includes a scissor assembly 9-3, and the transmission rod 9-2 is fixedly connected to the second armrest assembly 2 through the scissor assembly 9-3.

[0048] Specifically, as Figure 6 shown, the scissor assembly 9-3 is composed of multiple groups of X-shaped cross bars. Each group of cross bars is connected in the middle through a hinge point, so that when it is pushed or pulled, it can expand or contract like scissors. One end of the scissor assembly 9-3 is fixedly connected to the first armrest assembly 3, and the other end is fixedly connected to the second armrest assembly 2. One end of the transmission rod 9-2 close to the second armrest assembly 2 is connected to the hinge point of any group of bars. Thus, when the eccentric wheel 9-1 drives the transmission rod 9-2 to move in a straight line, the transmission rod 9-2 will drive the scissor assembly 9-3 to expand or contract, and the scissor assembly 9-3 can directly push or pull the second armrest assembly 2 to move along the length direction of the first guide rail 3-1.

[0049] It should be noted that the specific position of the transmission rod 9-2 in the scissor assembly 9-3 has a significant impact on the movement height of the armrest assembly. By adjusting the connection position of the transmission rod 9-2 on the scissor assembly 9-3, the transmission effect of the transmission rod 9-2 can be amplified or maintained, thereby affecting the movement height of the second armrest assembly 2. Specifically, when the transmission rod 9-2 is connected to the hinge point close to the first armrest assembly 3, the linear movement of the transmission rod 9-2 is amplified by the scissor assembly 9-3, resulting in an increased expansion or contraction amplitude of the scissor assembly 9-3. In this way, the lifting height of the second armrest assembly 2 is greater than the eccentricity value of the eccentric wheel 9-1. When the transmission rod 9-2 is connected to the hinge point close to the second armrest assembly 2, the linear movement of the transmission rod 9-2 is directly converted into the movement of the scissor assembly 9-3, and the transmission effect is not amplified. At this time, the lifting height of the second armrest assembly 2 is equal to the eccentricity value of the eccentric wheel 9-1. Thus, in scenarios where a larger amplitude of height adjustment is required, the transmission rod 9-2 is arranged at the hinge point close to the first armrest assembly 3, so that the lifting height of the second armrest assembly 2 is amplified, which is suitable for the situation where the user needs a larger range of height adjustment. In scenarios where precise control of height adjustment is required, the transmission rod 9-2 is arranged at the hinge point close to the second armrest assembly 2, so that the lifting height of the second armrest assembly 2 is equal to the eccentricity value of the eccentric wheel 9-1, which is suitable for the situation where the user needs precise height adjustment.

[0050] Optionally, the driving source 4 can drive the rotation of the first rotating member 4-1 or the second rotating member 4-2 in various ways, such as belt drive, chain drive, first gear 7-1 drive, and direct drive, etc. Each driving method has its specific applicable occasions and advantages. For example, when the driving source 4 uses the direct drive method, it can be directly connected to the first rotating member 4-1 or the second rotating member 4-2. This method is simple and direct, can provide efficient rotational power transmission, is suitable for applications that require quick response and precise control, and can reduce transmission losses and motion delays, making the lifting motion more stable and reliable. Selecting the appropriate driving method depends on specific application requirements, including power demand, transmission efficiency, accuracy requirements, noise control, and the reliability and maintenance cost of the equipment. The correct selection of the driving method can effectively improve the performance and service life of the equipment.

[0051] Preferably, as Figures 3 to 6 shown, the driving source 4 can drive the rotation of the first rotating member 4-1 or the second rotating member 4-2 through belt drive. At this time, in addition to the driving source 4, the driving assembly further includes a pulley assembly. The pulley assembly includes a first pulley 4-3 connected to the driving source 4 and a second pulley 4-4 connected to the first rotating member 4-1 or the second rotating member 4-2. The first pulley 4-3 and the second pulley 4-4 transmit power through a belt 4-5. The driving source 4 rotates the first pulley 4-3, and the belt 4-5 makes the second pulley 4-4 rotate accordingly through the teeth or grooves fixed on the first pulley 4-3 and the second pulley 4-4. In this way, the power of the driving source 4 is effectively transmitted to the first rotating member 4-1 or the second rotating member 4-2 to complete the required rotating operation. The advantage of this method is that it can provide a certain separation and buffering between the driving source 4 and the first rotating member 4-1 or the second rotating member 4-2, reducing the direct impact of the driving system on the rotating components, thereby reducing vibration and noise and enhancing the stability and safety of the system. In addition, the belt drive can also adjust the rotational speed and torque output by selecting different belts 4-5 and pulley sizes to adapt to different working requirements.

[0052] On the other hand, an embodiment of the present application provides a massage device, including a massage device body 1 and a left armrest structure and a right armrest structure installed on the massage device body 1. The left armrest structure and / or the right armrest structure is any one of the above-mentioned armrest structures. The left armrest structure and the right armrest structure serve as user armrests and supports, aiming to provide a comfortable massage posture and stable support. The massage device can be a massage chair, a massage bed, etc. Since the left armrest structure and / or the right armrest structure of the massage device adopts any one of the above-mentioned armrest structures, it thus has the same beneficial effects, which can be specifically referred to the previous description and will not be elaborated here.

[0053] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
