[0023] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0024] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. It should be noted that, unless otherwise specified, the various features in the embodiments of this application can be combined with each other, and the combined embodiments are still within the protection scope of this application.

[0025] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0026] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this application is in use. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0027] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," not that the structure must be completely horizontal, but can be slightly tilted.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0029] One aspect of this application provides an armrest 2 suitable for a massage chair, designed to enhance the effect of hand massage through a telescopic design. For example... Figure 1 and Figure 2 As shown, the armrest 2 includes an armrest body 3, a massage unit 4, and a drive source 6. The armrest body 3 serves as a support and mounting structure, stably supporting the massage unit 4 and its drive source 6, ensuring stability and safety throughout the massage process. The massage unit 4 is retractably mounted to the armrest body 3 and is designed with a dedicated massage cavity for placing the hands. This design not only provides users with a comfortable hand placement space but also promotes healthy hand massage through its unique functional structure.

[0030] The drive source 6 is connected to the massage unit 4, allowing the massage unit 4 to extend and retract along the length of the armrest body 3. This extension and retraction effectively stretches the muscles and fascia of the hand, relieving tension and fatigue. As the hand extends and retracts, the parts of the massage unit 4 that contact the hand produce different massage effects, deeply stimulating the muscle groups and fascia tissues, thereby improving blood circulation and promoting blood flow. This function not only relieves fatigue from prolonged hand use but also prevents hand stiffness and soreness, enhancing overall comfort. This massage method meets the user's need for comprehensive hand massage, improves hand health, and enhances the overall functionality of the massage chair.

[0031] It should be noted that a motor 6 is typically used as the drive source, installed at the base of the armrest body 3 and securely connected to the armrest body 3 via a fastener 7. This ensures stable operation of the motor during work, preventing displacement or loosening due to vibration. The forward and reverse rotation of the motor controls the extension and retraction of the massage section 4. When the motor rotates forward, the drive source 6 extends the massage section 4, effectively massaging and stretching the hand within the massage cavity. When the motor rotates in reverse, the massage section 4 retracts, allowing users to easily adjust their hand position in different usage scenarios. The precise control of the motor's operation allows for detailed adjustments to the massage section 4 as needed, ensuring that the depth and breadth of the hand massage can be flexibly varied according to individual requirements.

[0032] Overall, this armrest design not only enhances the hand massage effect but also boasts advantages such as simple structure and controllable cost. Compared to traditional, complex hand massage devices, this design maintains efficient massage while reducing production costs and manufacturing complexity. Therefore, this armrest design can be widely used in various massage chairs, helping manufacturers achieve multifunctional hand massage capabilities at a lower cost, meeting users' growing demand for hand relaxation and soothing. Furthermore, its simple design makes it easy to integrate into existing massage chair products, promoting the popularization and development of massage chair technology and enhancing the user experience.

[0033] Optionally, the massage part 4 is made of a flexible material to ensure sufficient comfort and durability during long-term use. To achieve this, the massage part 4 can be made of elastic and flexible silicone material. This material not only possesses high softness, allowing it to precisely conform to the curves of the hand for a comfortable massage experience, but also has a certain degree of elasticity, enabling it to smoothly extend and retract under the driving force of the drive source 6. In addition, the silicone material can effectively disperse external force during use, reducing potential discomfort to the hand during massage, making the massage process gentler and less damaging to the skin. Furthermore, silicone has good temperature resistance and aging resistance, maintaining its original elasticity and strength during prolonged use, extending the service life of the massage part 4.

[0034] Besides silicone, the massage section 4 can also use other flexible materials, such as thermoplastic elastomers (TPE) or memory foam. These materials also possess excellent elasticity, flexibility, and comfort, allowing for appropriate deformation according to the user's hand shape to provide a more precise massage effect. Thermoplastic elastomers (TPE) have excellent abrasion and tear resistance, maintaining their superior performance even after prolonged and repeated use, and are not prone to aging or wear. Memory foam, on the other hand, can adaptively change according to the pressure and shape of the hand, providing a more conforming and personalized comfort during the massage.

[0035] Overall, the design and material selection of the massage unit 4 effectively enhance the comfort and effectiveness of the armrest 2 in actual use. Driven by the power source 6, the massage unit 4 smoothly performs the stretching and contracting function of hand massage, thereby relieving hand fatigue, soothing muscles, and improving blood circulation. Furthermore, the durability of the materials ensures that this massage device maintains stable performance during long-term, repeated use, guaranteeing users a lasting and efficient massage experience and significantly improving the lifespan and performance stability of the massage chair.

[0036] Optionally, such as Figure 1 As shown, in order to enhance the effect and comfort of hand stretching massage, the armrest 2 also includes an air pump and an airbag 5. The air pump is installed in the armrest body 3, and the airbag 5 is installed in the massage cavity of the massage part 4. The air pump is connected to the airbag 5 via an air tube.

[0037] Specifically, when the hand is placed inside the airbag 5, the air pump starts working, delivering air to the airbag 5 through the air tube, causing the airbag 5 to inflate. During the inflation of the airbag 5, the inner side of the airbag 5 provides a soft and supportive contact surface for the hand, effectively enhancing comfort and massage effect during the stretching process. At the same time, the outer side of the airbag 5 fits tightly against the inner wall of the massage cavity, ensuring that the airbag 5 does not move unnecessarily during inflation, thereby improving the stability and precision of the massage unit 4. The close contact between the inner side of the airbag 5 and the hand allows the hand to receive better support during the stretching process, relieving hand fatigue and tension, helping to promote blood circulation, and relaxing hand muscles and fascia. The soft contact surface of the inflated airbag 5 effectively increases the depth and coverage of the massage, avoiding discomfort or overstretching during hand massage, ensuring the comfort and effectiveness of the massage. After the stretching massage is completed, in order to ensure that the massage unit 4 can return to its original shape, the air pump will deflate, causing the airbag 5 to contract. This process helps the airbag 5 gradually reduce its volume, allowing the massage section 4 to return to its original state.

[0038] Alternatively, in addition to using airbags 5 to provide support and pressure, a spring structure can be employed inside the massage cavity. A retractable spring is installed at an appropriate location inside the massage cavity. A drive source 6 drives a cam or other mechanical structure to compress or release the spring, allowing the massage unit 4 to provide support and a massage effect to the user's hand when extended. This approach reduces the complexity of the air circuit system and improves the reliability and response speed of the massage.

[0039] Optionally, such as Figure 2As shown, the armrest 2 also includes a guide rail 12 and a slider 13. The guide rail 12 is installed on the armrest body 3 along its length. One side of the slider 13 is slidably connected to the guide rail 12, while the other side of the slider 13 is fixedly connected to the massage unit 4. The drive source 6 is connected to the massage unit 4 via the slider 13. With this structure, the slider 13 can slide smoothly on the guide rail 12, thereby driving the massage unit 4 to extend and retract along the length of the armrest body 3. The slider 13 is typically designed as a slider, which is connected to the guide rail 12 through a sliding nesting mechanism.

[0040] Specifically, the drive source 6, through its connection with the slider 13, controls its smooth sliding along the guide rail 12. When the drive source 6 is activated, the slider 13 is driven to move linearly along a predetermined path on the guide rail 12. This movement causes the massage unit 4 to extend and retract, thereby stretching the hand. The guide rail 12 is installed along the length of the armrest body 3, providing a precise guiding path for the movement of the slider 13. The design of the guide rail 12 ensures that the slider 13 can slide smoothly along a fixed route, preventing the massage unit 4 from deviating from the predetermined trajectory due to positional shift or instability of the slider 13 during the massage process.

[0041] This design effectively controls the movement path of the massage unit 4 during the massage process, ensuring that the extension and retraction movements of the massage unit 4 remain within a controllable range. Through precise guiding and sliding design, the massage unit 4 can smoothly move in a straight line along a predetermined path, maintaining a stable position and posture. This not only ensures that the stretching movements of the massage unit 4 have a certain strength and depth, but also avoids potential injury or discomfort to the hands due to path deviation. Therefore, the entire massage process is more precise and comfortable, and there will be no discomfort or poor effect caused by the displacement of the massage unit 4.

[0042] Optionally, such as Figure 2 As shown, the armrest 2 also includes a first transmission assembly, which includes a lead screw 9 and a lead screw nut 10 threadedly connected to the lead screw 9. The output end of the drive source 6 is driven by the lead screw 9 via a pulley 8, and the lead screw nut 10 is connected to the sliding member 13. The driving force of the drive source 6 is transmitted to the lead screw 9 through the pulley 8, causing the lead screw 9 to rotate. The rotation of the lead screw 9, through the threaded connection, causes the lead screw nut 10 to move along the axial direction of the lead screw 9 (i.e., the length direction of the armrest body 3), thereby driving the sliding member 13 to slide along the guide rail 12. This transmission method can provide efficient and precise power transmission, allowing the massage unit 4 to extend and retract smoothly and precisely as needed, controlling the depth and intensity of the massage, and ensuring that the hands receive appropriate stretching and massage.

[0043] Optionally, the armrest 2 also includes a second transmission assembly, which includes a meshing gear and a rack. The output end of the drive source 6 is connected to the gear drive, and the rack is connected to the massage part 4. The drive source 6 transmits power to the gear through its output end. The rotation of the gear drives the meshing rack to translate along the direction of the rack, thereby converting the rotational motion into the linear motion of the slider 13. The movement of the slider 13 then drives the massage part 4 to extend and retract along the length of the armrest body 3, achieving a stretching massage for the hand.

[0044] Optionally, the armrest 2 also includes a controller, which can be installed independently on the armrest body 3 or centrally integrated into the main control system of the massage chair. Independent installation increases the modularity and flexibility of the controller, facilitating installation, debugging, and maintenance. The controller is electrically connected to the drive source 6 and the air pump, respectively, thereby optimizing the precision and comfort of the hand stretching massage process and making the entire massage process more intelligent and systematic.

[0045] When a user needs a hand stretching massage, the controller first powers on the motor and drives it to rotate forward. The motor, driven by either the first or second transmission component, propels the slider 13 smoothly along the guide rail 12. The movement of the slider 13 causes the massage head 4 to gradually extend outward, effectively stretching the hand. Simultaneously, the controller activates the air pump to inflate the airbag 5, causing it to expand and conform to the user's hand, providing additional support and comfort. The expansion of the airbag 5 enhances the massage effect and provides gentle support during the stretching process, allowing the hand to fully relax and relieve fatigue and tension.

[0046] When the user needs to stop the hand massage, the controller reverses the motor, causing it to rotate in the opposite direction and return the massage unit 4 to its initial position. Simultaneously, the controller also controls the air pump to deflate, causing the airbag 5 to gradually contract, reducing the support force on the hands and helping it return to its original state. The contraction of the airbag 5 allows the massage unit 4 to retract more smoothly and ensures it ultimately returns to its original position. Through this process, the massage chair completes a full stretching massage, ensuring the continuity and comfort of the massage effect.

[0047] Optionally, the armrest 2 also includes an operating terminal, such as a control panel or mobile app, which connects to the controller via wired or wireless communication. Users can easily send commands through the operating terminal to control the hand stretching and massage function. The operating terminal acts as an interactive interface between the user and the massage device, allowing users to set parameters such as stretching intensity and stretching time according to their individual needs. This design allows users to more flexibly adjust the massage experience and enjoy a personalized hand massage.

[0048] The operating terminal transmits user commands to the controller, which then controls the operation of the drive source 6 and the air pump based on the received commands. First, the controller adjusts the output of the drive source 6 according to the user-set stretching intensity, allowing the massage unit 4 to smoothly extend and retract as needed. Simultaneously, the air pump's inflation level can also be adjusted according to the set stretching intensity to provide different levels of hand stretching effect. For example, when the user selects a stronger stretching intensity, the air pump inflates more air to provide stronger support and a better massage effect; conversely, when a lighter stretching intensity is selected, the air pump inflates less air to ensure a gentler massage. In this way, users can obtain a precise and adjustable stretching experience during the massage, meeting different needs and comfort requirements.

[0049] Throughout the stretching process, users can adjust the stretching intensity or duration at any time via the control terminal's interface, and even pause the massage. The controller will respond to user commands in real time, dynamically adjusting the operating status of the drive source 6 and the air pump to ensure the comfort and controllability of the massage. Whether increasing the stretching intensity or adjusting the massage duration, the controller can precisely control the device's operating status, making the massage process more flexible and personalized. Furthermore, the real-time feedback and adjustment functions allow users to maintain a high degree of control during the massage, adjusting it at any time according to individual needs to achieve the most suitable massage effect.

[0050] Overall, the introduction of the control terminal makes the interaction between the user and the Armrest 2 massage device more intuitive and convenient. Through intelligent control, users can finely adjust the massage parameters according to their personal preferences, enjoying a personalized and adjustable hand stretching massage experience. This design not only improves the ease of use of the massage chair but also enhances the user's sense of participation and control, making the entire massage process more suitable for the needs of different users and improving the overall comfort and flexibility of the user experience.

[0051] Optionally, such as Figure 2 As shown, the armrest 2 also includes a travel monitoring component 11, such as a travel monitoring PCB board, mounted on the massage unit 4 or the sliding member 13. The main function of the travel monitoring component 11 is to monitor the displacement of the sliding member 13 in real time, thereby accurately obtaining the extension or retraction degree of the massage unit 4. Through electrical connection with the controller, the travel monitoring component 11 can feed back the monitored displacement signal to the controller, providing the controller with accurate displacement data to ensure that the extension and retraction of the massage unit 4 can be adjusted according to the preset travel requirements.

[0052] The stroke monitoring component 11 precisely monitors the extension or retraction process of the massage unit 4 by tracking the position changes of the slider 13 in real time. This monitoring technology uses sensors to capture the displacement of the slider 13 and continuously transmits this displacement data to the controller. Based on these real-time feedback signals, the controller can accurately understand the current position of the massage unit 4 and dynamically adjust the operating state of the drive source 6 according to user-set parameters (such as tension intensity, massage duration, etc.). Through this precise control method, the massage unit 4 can precisely extend to the designated position according to the set stroke requirements, avoiding inaccurate or uncomfortable massage effects due to stroke errors.

[0053] The close collaboration between the travel monitoring component 11 and the controller makes the entire massage process more intelligent and precise. Based on the data fed back by the travel monitoring component 11, the controller can adjust the output power and direction of the drive source 6 in real time, ensuring that the massage unit 4 always extends and retracts along the predetermined path. Regardless of the user's selected stretching intensity, the travel monitoring component 11 provides accurate data feedback, ensuring that the massage unit 4 smoothly reaches the target position, avoiding exceeding the predetermined travel or experiencing unstable extension and retraction, thereby guaranteeing the stability and comfort of the massage process.

[0054] This design not only improves the extension and retraction accuracy of the massage unit 4, but also effectively reduces discomfort or mechanical damage caused by stroke errors. The stroke monitoring component 11 can adjust the operating status of the massage unit 4 in real time to ensure that each stretch achieves the ideal effect, maximizing the user experience. In addition, precise stroke control also helps extend the service life of the device and reduces the risk of damage caused by excessive or insufficient stroke.

[0055] Another aspect of this application provides a massage chair, such as... Figure 3 As shown, the massage chair includes a massage chair body 1 and an armrest 2 of any of the above types, with the armrest body 3 of the armrest 2 installed on the massage chair body 1. Since the massage chair uses the armrest 2 described above, it also has the same beneficial effects as the armrest 2, which will not be described in detail here.

[0056] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
