Description

Technical Field

[0001] The present invention relates to the technical field of massage chairs, and in particular to a massage chair with a seat that moves forward. Background Art

[0002] In modern life, people's work and life pace is accelerating, and physical fatigue and stress are also increasing. Massage chairs, as a device that can effectively relieve fatigue and relax the body and mind, are favored by more and more people. As consumers' requirements for the use experience of massage chairs continue to increase, their functions and designs are also continuously evolving. As an important part of the massage chair, the position and adjustability of the seat have a key impact on the user's comfort.

[0003] With the progress of society and the popularity of massage chairs, the design of large massage chairs has gradually exposed some problems that are not friendly to specific user groups. In particular, the leg and foot massage mechanisms of many massage chairs are usually located in front of the seat, requiring users to cross a width of about 40 cm to sit down. This design not only increases the difficulty of use for the elderly, the disabled, and people with limited mobility, but also may bring safety hazards. Therefore, improving the design of massage chairs to make them easier to sit in is crucial to improving the universal applicability and user experience of massage chairs. In order to improve the convenience of users sitting down, there are two main design methods for massage chairs on the market. Cancelling the foot massage function: Some massage chair designs cancel the foot massage function and adopt a leg folding design, equipped with airbag massage or sofa surface dual functions, so that users can stand like usual and sit down directly to use the massage chair. However, this design sacrifices the foot massage function and is not friendly enough for users who need foot massage. Side flip design: Another design adopts a side flip method to directly expose the seat from the side, and the user closes the folded side panel after sitting down. This design requires extra space to open the side panels, which greatly restricts the placement of the massage chair and is not suitable for most families with limited space.

[0004] The above two different massage devices have certain limitations. The first solution sacrifices the foot massage function, and the second solution has high space requirements. Therefore, the market still needs a massage chair design that can satisfy the convenience of users sitting down, provide comprehensive massage functions, and not require high family space. Therefore, a massage chair with a forward seat is proposed. Summary of the invention

[0005] The purpose of the present invention is to solve the problems existing in the prior art that the leg and foot massage mechanisms of large massage chairs require users to sit across a width of about 40 cm, which brings inconvenience and safety hazards to specific groups of people. The two design methods each have defects. Canceling the foot massage function and adopting a leg folding design will sacrifice the foot massage needs. The side-flip design requires additional space and is limited by the placement position. A massage chair with a forward seat is proposed.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A massage chair with a seat that moves forward comprises a base support module, wherein a U-shaped forward movement module is slidably connected to the top of the base support module, a massage chair back frame is fixedly connected to the top of the base support module, and a massage chair back frame is fixedly connected to the side of the base support module. The U-shaped forward movement module comprises a seat surface part, and a sliding module is fixedly connected to the bottom of the seat surface part, a driven screw is fixedly connected to the bottom of the U-shaped forward movement module, the driven screw is threadedly connected to a second bevel gear, the second bevel gear is meshedly connected to a first bevel gear, a driving shaft is fixedly connected to the side of the first bevel gear away from the second bevel gear, a rotating wheel is provided on the outer sleeve of the driving shaft, the rotating wheel is transmission-connected to a transmission belt, the transmission belt is transmission-connected to the output end of an output motor, a bearing is provided on the outer sleeve of the driving shaft, the bearing is fixed in a groove of a fixed block, the fixed block is fixed on the top of a supporting base, the supporting base is fixedly connected to a slide rail, the slide rail is slidably connected to the sliding module, and a leg and foot 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 on the top of the support base, and the transmission screw rods are distributed on both sides of the seat surface. With this layout, the middle hollow position is used to leave space for the movement to move, and the massage chair movement can move to the bottom of the buttocks for massage.

[0010] A sensor for receiving signals is arranged below the seat surface part. The sensor is used to control the output end of the output motor. The sensor is a pressure sensor, which can sense when the user sits on the seat surface part, so that the user can issue commands.

[0011] A motor transmission module is fixedly connected above the support base, and the motor transmission module includes an output motor, a transmission belt, and a rotating wheel. The motor transmission module is linearly connected to the control module, and the control module is linearly connected to the interactive module. The interactive module includes an indicator light, a speaker, etc., so as to ensure that the user understands the real-time status of the device.

[0012] An interactive module including a feedback module and a control panel is arranged on the outside of the massage chair back frame. The control panel is used to issue instructions to the control module. The feedback module is fixed on the surface of the U-shaped forward moving module. The control panel includes touch buttons, remote controls, etc. so that the user can clearly use the device. The setting of the interactive module facilitates the interactive operation between the user and the massage chair. The control panel allows the user to issue instructions to the control module according to their own needs, such as massage intensity, massage mode, seat position adjustment, etc., so that the user can easily control the various functions of the massage chair.

[0013] A connection block is arranged above the support base, and the connection block above the support base is rotatably connected to the second bevel gear. The setting of the connection block enables the second bevel gear to stably rotate above the support base, providing a stable support and rotation center for the gear transmission system. On the one hand, the stability of the gear transmission system during power transmission is ensured, and the vibration and noise generated by unstable gear rotation are reduced.

[0014] The side of the leg and foot massage module is provided with a calf airbag splint for placing the legs.

[0015] The massage chair back frame is internally provided with a groove for placing the seat surface portion.

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

[0017] 1. In the present invention, the massage chair with a forward seat portion solves the problem that the leg and foot massage mechanisms of existing large massage chairs require users to sit across a width of about 40 cm through the forward and backward functions of the seat portion. For the elderly, disabled people and people with limited mobility, they can sit without crossing a large width, which greatly reduces the difficulty of use and avoids the potential safety hazards caused by difficulty in crossing, improves the convenience and safety of these specific people in using the massage chair, and enables more users to use the massage chair easily.

[0018] 2. Compared with the leg folding design and side-flipping design of existing massage chairs that cancel the foot massage function, the massage chair with the forward seat does not need to sacrifice the foot massage function, nor does it require additional space for side-flipping operation, thus avoiding the restriction on the placement of the massage chair due to side-flipping. While satisfying the user's seating convenience, the foot massage function is fully retained, and at the same time, it can better adapt to various family space layouts, improve the user experience, and optimize the overall space utilization efficiency of the massage chair.

A rotating wheel 8.3 is sleeved on the outside of the driving shaft 9. The rotating wheel 8.3 is transmission-connected with a transmission belt 8.2. The transmission belt 8.2 is transmission-connected to the output end of the output motor 8.1. A bearing 10 is sleeved on the outside of the driving shaft 9. The bearing 10 is fixed in the groove of the fixed block 16. The fixed block 16 is fixed above the support base 15. The support base 15 is fixedly connected with a slide rail 5. A sliding module 6 is slidably connected above the slide rail 5. A leg and foot massage module 3 is installed on the side of the base bracket module 4.

[0028] In one embodiment, for the output motor 8 . 1 , the output motor 8 . 1 is fixed above the supporting base 15 .

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

[0030] In one embodiment, for the above-mentioned sensor 14, a sensor 14 for receiving a signal is arranged below the seat surface portion 7, and the sensor 14 is used to control the output end of the output motor 8.1.

[0031] In one embodiment, for the above-mentioned support base 15, a motor transmission module 8 is fixedly connected above the support base 15, and the motor transmission module 8 includes an output motor 8.1, a transmission belt 8.2, and a rotating wheel 8.3. The motor transmission 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 transmission module 8 integrates the output motor 8.1, the transmission belt 8.2 and the rotating wheel 8.3, making the power transmission more compact and orderly. By fixing the motor transmission module 8 above the support base 15, a close layout with other key components is achieved, reducing energy loss during power transmission and improving the efficiency of power transmission.

[0033] In one embodiment, for the above-mentioned massage chair back frame 2, an interactive module 18 is arranged outside the massage chair back frame 2, including a feedback module 18.1 and a control panel 18.2. The control panel 18.2 is used to issue instructions to the control module 19, and the feedback module 18.1 is fixed on the surface of the U-shaped forward movement module 1.

[0034] In this embodiment, the setting of the interactive module 18 facilitates the interactive operation between the user and the massage chair. The control panel 18.2 allows the user to issue instructions to the control module 19 according to their needs, such as massage intensity, massage mode, seat position adjustment, etc., so that the user can easily control various functions of the massage chair.

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

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

[0037] In one embodiment, for the above-mentioned leg and foot massage module 3, a calf airbag splint 17 for placing the legs is provided on the side of the leg and foot massage module 3.

[0038] In one embodiment, for the massage chair back frame 2 described above, a groove for placing the seat surface portion 7 is provided inside the massage chair back frame 2 .

[0039] The working principle of a massage chair with a forward-moving seat in the present invention is that the user first issues an instruction through the interactive module 18.2, which is a touch screen button arranged above the massage chair back frame 2. The user can easily select various operation options by touching the touch screen button. These operation instructions will be transmitted to the control module 19, which will process and analyze the instructions and issue precise instructions for the seat to move forward or backward according to the user's needs. Subsequently, the motor transmission module 8 provides power, and the motor transmission module 8 includes a motor 8.1, a belt 8.2 and a driving shaft pulley 8.3. The motor 8.1 starts and drives the belt 8.2 to rotate. The belt 8.2 transmits power to the driving shaft pulley 8.3, thereby driving the driving shaft 9 to rotate.

[0040] The first bevel gear 11 fixed on the driving shaft 9 will rotate with the rotation of the driving shaft 9. The first bevel gear 11 and the second bevel gear 12 are meshed with each other, so the rotation of the first bevel gear 11 will drive the second bevel gear 12 to rotate. This gear transmission method can effectively change the direction and torque of power transmission, so that the power is transmitted more smoothly and efficiently. The second bevel gear 12 transmits the rotating power to the driven screw 13, providing power for the driven screw 13. The driven screw 13 is connected to the sliding module 6 under the seat surface part 7. After obtaining power, it drives the sliding module 6 fixed under the seat surface part 7 to move on the slide rail 5.

[0041] In this process, the sensor module 14 plays an important monitoring and control role. When the sensor module 14 receives a signal, the seat portion 7 stops sliding. The sensor module 14 can sense signals in a variety of ways, such as sensing physical quantities such as pressure and displacement. When the user presses down on the seat portion 7, the sensor module 14 will receive a command, indicating that there is a user on the seat portion 7. At this time, the entire system will enter a state of waiting for further user operations, waiting for the user to issue instructions through the interactive module 18.2.

[0042] The user is prompted through the feedback module 18.1, which includes an indicator light set on the surface of the massage chair back frame 2. When the system receives an instruction, completes an operation, or a certain state occurs, the indicator light will illuminate, and will be accompanied by a variety of prompts such as sound prompts, providing the user with intuitive operation feedback and making it convenient for the user to understand the working status of the massage chair. At the same time, the massage chair uses the power module to provide the required power for the entire system to ensure the normal operation of each module, especially the normal operation of the motor 8.1.

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