Description

Technical Field

[0001] This invention relates to the field of massage chair technology, and more particularly to a massage chair with a forward-moving seat. Background Technology

[0002] In modern life, the pace of work and life is accelerating, leading to increased physical fatigue and stress. Massage chairs, as devices that effectively relieve fatigue and relax the mind and body, are gaining popularity. As consumers' demands for a better user experience continue to rise, the functions and designs of massage chairs are constantly evolving. The seat, as a crucial component of the massage chair, has a key impact on user comfort due to its position and adjustability.

[0003] With social progress and the widespread use of massage chairs, the design of large massage chairs has gradually revealed some issues that are not user-friendly for certain groups. In particular, the leg and foot massage mechanisms of many massage chairs are usually located at the front of the seat, requiring users to have a width of about 40 centimeters to sit down. This design not only increases the difficulty of use for the elderly, disabled, and people with mobility impairments, but may also pose safety hazards. Therefore, improving the design of massage chairs to make them easier to sit in is crucial to improving their universal applicability and user experience. Currently, massage chairs on the market mainly adopt two design methods to improve the convenience of users sitting down: Eliminating foot massage: Some massage chair designs have eliminated the foot massage function, adopting a leg-folding design, equipped with airbag massage or a sofa-like dual function, so that users can sit down directly while standing as usual. However, this design sacrifices the foot massage function, which is not user-friendly for users who need foot massage. Side-folding design: Another design uses a side-folding method, directly exposing the seat from the side, and closing the folding side panel after the user sits down. This design requires additional space to open the side panels, which greatly limits the placement of the massage chair and makes it unsuitable for most families with limited space.

[0004] Both of the aforementioned massage devices have certain limitations. The first solution sacrifices foot massage functionality, while the second requires more space. Therefore, the market still needs a massage chair design that can satisfy users' convenience in sitting down, provide comprehensive massage functions, and not require much space in the home. This has led to the proposal of a massage chair with a forward-moving seat. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies. In large massage chairs, the leg and foot massage mechanisms require users to sit across a width of approximately 40 centimeters, which poses inconvenience and safety hazards to certain groups. Eliminating the foot massage function and adopting a leg folding design sacrifices the need for foot massage, while the side-folding design requires additional space and is limited by placement. Therefore, this invention proposes a massage chair with a forward-moving seat.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A massage chair with a forward-moving seat includes a base support module. A U-shaped forward-moving module is slidably connected above the base support module. A massage chair backrest is fixedly connected above the base support module and to the side of the base support module. The U-shaped forward-moving module includes a seat portion. A sliding module is fixedly connected below the seat portion. A driven screw is fixedly connected below the U-shaped forward-moving module. The driven screw is threadedly connected to a second bevel gear. The second bevel gear meshes with a first bevel gear. A drive shaft is fixedly connected to the side of the first bevel gear away from the second bevel gear. A rotating wheel is sleeved on the outside of the drive shaft. A drive belt is driven by the rotating wheel and is connected to the output end of an output motor. A bearing is sleeved on the outside of the drive shaft. The bearing is fixed in a groove of a fixed block. The fixed block is fixed above a support base. A slide rail is fixedly connected to the support base. A sliding module is slidably connected above the slide rail. A leg massage module is installed on the side of the base support module.

[0008] The above technical solution further includes:

[0009] The output motor is fixed above the support base, and the transmission screws are distributed on both sides of the seat surface. This layout leaves space for the movement of the massage chair mechanism in the middle, allowing the massage chair mechanism to move to the bottom of the buttocks for massage.

[0010] A sensor for receiving signals is installed below the seat surface. The sensor is used to control the output of the output motor. This sensor is a pressure sensor, which can be sensed when the user sits on the seat surface, thereby enabling the user to issue commands.

[0011] A motor drive module is fixedly connected above the support base. The motor drive module includes an output motor, a drive belt, and a pulley. The motor drive module is linearly connected to the control module, and the control module is linearly connected to the interaction module. The interaction module includes indicator lights, speakers, etc., so as to ensure that the user understands the real-time status of the device.

[0012] The massage chair backrest is equipped with an interactive module, including a feedback module and a control panel. The control panel is used to issue commands to the control module. The feedback module is fixed to the surface of the U-shaped forward-moving module. The control panel includes touch buttons, a remote control, etc., so that users can clearly use the device. The interactive module facilitates the interaction between the user and the massage chair. The control panel allows users to issue commands to the control module according to their needs, such as massage intensity, massage mode, seat position adjustment, etc., so that users can easily control the various functions of the massage chair.

[0013] A connecting block is provided above the support base, and this connecting block is rotatably connected to the second bevel gear. The connecting block allows the second bevel gear to rotate stably above the support base, providing stable support and a rotation center for the gear transmission system. This ensures the stability of the gear transmission system during power transmission and reduces vibration and noise caused by unstable gear rotation.

[0014] The leg and foot massage module has a calf airbag splint on its side for placing the legs.

[0015] The massage chair back frame has a groove inside for placing the seat.

[0016] The present invention has the following beneficial effects:

[0017] 1. In this invention, the massage chair with a forward-moving seat solves the problem of existing large massage chairs requiring users to cross approximately 40 centimeters in width for leg and foot massage mechanisms. For the elderly, disabled, and those with mobility issues, this eliminates the need to cross a large width to sit, significantly reducing the difficulty of use, avoiding potential safety hazards caused by difficulty in crossing, and improving the convenience and safety of using the massage chair for these specific groups, enabling more users to easily use the massage chair.

[0018] 2. Compared to existing massage chairs that omit the foot massage function with leg folding and side-flipping designs, this invention, with its forward-positioned seat, neither sacrifices the foot massage function nor requires additional space for side-flipping, thus avoiding limitations on the chair's placement due to side-flipping. While ensuring user comfort, it fully retains functions such as foot massage, better adapts to various home layouts, enhances the user experience, and optimizes the overall space utilization efficiency of the massage chair.

A leg massage module 3 is installed on the side of the base support module 4.

[0028] In one embodiment, the output motor 8.1 is fixed above the support base 15.

[0029] In this embodiment, the support base 15 is usually a basic component in the massage chair structure and has high stability. The output motor 8.1 is installed here, providing a stable installation platform for the motor and ensuring that the motor will not be displaced due to vibration or other external forces during operation, thus ensuring the normal operation of the motor.

[0030] In one embodiment, for the aforementioned sensor 14, a sensor 14 for receiving signals is provided below the seat portion 7, and the sensor 14 is used to control the output terminal of the output motor 8.1.

[0031] In one embodiment, for the support base 15, a motor drive module 8 is fixedly connected above the support base 15. The motor drive module 8 includes an output motor 8.1, a drive belt 8.2, and a pulley 8.3. The motor drive module 8 is linearly connected to the control module 19, and the control module 19 is linearly connected to the interaction module 18.

[0032] In this embodiment, the motor drive module 8 integrates the output motor 8.1, the drive belt 8.2, and the pulley 8.3, making the power transmission more compact and orderly. By fixing the motor drive module 8 above the support base 15, a close layout with other key components is achieved, reducing energy loss during power transmission and improving power transmission efficiency.

[0033] In one embodiment, for the massage chair backrest 2, an interaction module 18 is provided on the outside of the massage chair backrest 2, including a feedback module 18.1 and a control panel 18.2. The control panel 18.2 is used to issue commands to the control module 19, and the feedback module 18.1 is fixed on the surface of the U-shaped forward moving module 1.

[0034] In this embodiment, the interactive module 18 facilitates user interaction with the massage chair. The control panel 18.2 allows users to issue commands to the control module 19 according to their needs, such as massage intensity, massage mode, and seat position adjustment, enabling users to easily control various functions of the massage chair.

[0035] In one embodiment, for the second bevel gear 12, a connecting block is provided above the support base 15, and the connecting block above the support base 15 is rotatably connected to the second bevel gear 12.

[0036] In this embodiment, the connecting block allows the second bevel gear 12 to rotate stably above the support base 15, providing stable support and a rotation center for the gear transmission system. On the one hand, this ensures the stability of the gear transmission system during power transmission, reduces vibration and noise caused by unstable gear rotation, and improves the comfort of the massage chair. On the other hand, it provides precise positional constraints for the rotation of the second bevel gear 12, making the gear transmission more accurate and helping to efficiently and smoothly transmit the power generated by the output motor 8.1 to the subsequent mechanical structure.

[0037] In one embodiment, the leg massage module 3 described above has a calf airbag splint 17 for placing the leg on its side.

[0038] In one embodiment, the massage chair backrest 2 described above has an internal groove for placing the seat portion 7.

[0039] The working principle of the massage chair with a forward-moving seat in this invention is as follows: The user first issues commands through the interaction module 18.2, which is a touchscreen button located above the massage chair backrest 2. The user can easily select various operation options by touching this touchscreen button. These operation commands are transmitted to the control module 19, which processes and analyzes the commands and issues precise commands to move the seat forward or backward according to the user's needs. Subsequently, power is provided by the motor transmission module 8, which includes a motor 8.1, a belt 8.2, and a drive shaft pulley 8.3. The motor 8.1 starts and drives the belt 8.2 to rotate, which in turn transmits power to the drive shaft pulley 8.3, thereby driving the drive shaft 9 to rotate.

[0040] The first bevel gear 11, fixed on the drive shaft 9, rotates with the drive shaft 9. The first bevel gear 11 meshes with the second bevel gear 12, so the rotation of the first bevel gear 11 drives the second bevel gear 12 to rotate. This gear transmission method effectively changes the direction and torque of power transmission, making power transmission smoother and more efficient. The second bevel gear 12 transmits the rotational power to the driven lead screw 13, providing power to the driven lead screw 13. The driven lead screw 13 is connected to the sliding module 6 below the seat surface 7. After receiving power, it drives the sliding module 6, fixed below the seat surface 7, to move on the slide rail 5.

[0041] During this process, sensor module 14 plays a crucial role in monitoring and control. When sensor module 14 receives a signal, seat portion 7 stops sliding. Sensor module 14 can sense signals in various ways, such as sensing physical quantities like pressure and displacement. When the user presses down on seat portion 7, sensor module 14 receives a command, indicating the presence of a user on seat portion 7. At this point, the entire system enters a state of waiting for further user operation, awaiting instructions from the user through interaction module 18.2.

[0042] The user is prompted by a feedback module 18.1, which includes indicator lights on the surface of the massage chair backrest 2. When the system receives a command, completes an operation, or encounters a certain status, the indicator lights illuminate, accompanied by various prompts such as sound alerts, providing intuitive operational feedback to the user and allowing them to easily understand the massage chair's working status. Simultaneously, the massage chair utilizes a power module to provide the necessary power to the entire system, ensuring the normal operation of each module, especially guaranteeing the proper functioning of motor 8.1.

[0043] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
