Description

Massage chair including a mounting device and a method for controlling a massage chair using the same

[0001] The present invention relates to a mounting device, and more specifically, to a massage chair including a 3-degree-of-freedom mounting device that is mounted on a motion chair or the like and can track and operate the user's movements, and a method for controlling the massage chair using the same.

[0002] A display device is a device designed to visually represent information, referring to a device that outputs data such as video, images, and text through a screen. Smartphones and tablets are representative examples. Display devices are utilized for various purposes, including providing information, entertainment, and work, and may also include interactive features such as touch screen technology or voice control.

[0003] To efficiently utilize such display devices, a mounting device is required that can fix the device or move and adjust it to a specific position.

[0004] A mounting device refers to a structure or mechanical system that stably secures a device, such as a display device, and supports the adjustment of its position and angle according to user requirements.

[0005] In particular, display mounting devices can enhance user convenience and viewing experience in various environments, such as functional furniture like massage chairs, motion beds, homes, offices, and vehicle interiors.

[0006] In particular, modern massage chairs provide additional functions beyond their primary role of applying pressure to and stretching the user's body, such as watching videos on a display, accessing exercise guides, and monitoring health status. Alternatively, users may wish to watch videos or other content using their own display devices while using the massage chair.

[0007] To effectively support these functions, the display device needs to be positioned at an optimal viewing distance and angle relative to the user. For example, when a user leans back or lies down in a massage chair, the display must be able to adjust its position and angle to align with the user's line of sight. To achieve this, the display mounting device requires the ability to move and adjust across multiple axes, such as up, down, left, right, and rotation.

[0008] Existing display mounting devices are primarily composed of fixed structures, which imposed many limitations on users in adjusting the angle or changing the position of the display.

[0009] To solve these problems, advanced devices such as stationary robots that implement multi-axis motion are also being researched and developed. However, there are problems such as the need to use complex mechanisms and expensive motors to implement multi-axis motion, or the limited range of motion of the display.

[0010] In particular, its complex structure, large size, and limited mobility to specific locations had limitations in meeting the diverse needs of users.

[0011] In conclusion, display mounting devices are playing an increasingly important role in modern life. These devices position display devices optimally for users, providing a comfortable viewing environment, and further contribute to efficient space utilization and enhanced user experience. However, current technology fails to fully meet the demands for structural simplification, cost efficiency, multi-axis flexibility, and user-customized control, making technological development to improve these aspects essential.

[0012] In other words, devices for mounting display devices are a field that requires continuous development to meet user demands in various environments. In particular, there was a need for technical improvements that enable flexible operation with a simple structure and enhance user convenience.

[0013] To solve the above problems, the present invention aims to provide a display mounting device capable of providing simple yet sufficient movement through three degrees of freedom.

[0014] In addition, the present invention aims to provide a mounting device that mounts a camera on the display mounting device to detect the movement of a user and automatically adjusts the position of the display device accordingly.

[0021] According to an embodiment, if the recognized user is not a registered user, the method further includes the step of performing user registration based on the face of the recognized user.

[0022] According to an embodiment, the step of recommending the massage course includes, if the recognized user is a registered user, the step of recommending a user-customized massage course based on previously stored information of the registered user.

[0023] According to an embodiment, the step of recommending a user-customized massage course includes the step of providing a massage course corresponding to the user's recognition information based on the service usage pattern of a registered user.

[0024] According to an embodiment, the method further includes a step of determining whether the position of the user's face is located within a preset distance from the mounting device.

[0025] According to an embodiment, if the position of the user's face is located within a preset distance from the mounting device, the method further includes the step of changing the position of the mounting device.

[0026] According to an embodiment, the method further includes: a step of recognizing the user's facial expression; a step of determining the user's state based on the user's facial expression; and a step of controlling the massage operation to change in response to the user's state.

[0053] FIG. 1 shows functional furniture equipped with a mounting device according to one embodiment of the present invention.

[0054] A mounting device (300) according to one embodiment of the present invention can be mounted on functional furniture. FIG. 1 illustrates a form mounted on a massage chair as an example. Here, functional furniture (10) may refer to a massage chair, a motion bed, or various furniture on which a user can sit or lie down.

[0055] In addition, this can be applied to all furniture requiring a mounting device that detects user movement and automatically adjusts the position of the display device accordingly, and this embodiment is not limited to specific furniture.

[0056] For convenience of explanation, this specification describes the case where the mounting device of the present invention is mounted on a massage chair.

[0057] The massage chair (10) includes a main body (100), and the main body has a structure that supports the user's body and provides a massage function.

[0058] The housing (200) is formed as a part of the main body (100) and serves as a case to protect the mounting device while also forming the outer structure of the main body.

[0059] The housing (200) is designed to accommodate a mounting device inside, and an opening (201) is formed on the upper surface to enable operation of the mounting device and position adjustment of the display device. The opening (201) provides a passage through which the mounting device can extend from inside the housing to the outside or be stored.

[0060] In one embodiment of the present invention, another mounting device (300) is built into or mounted in the housing (200) and operates, and can adjust the position of the display device or store it as needed.

[0061] FIG. 1 illustrates a storage mode of a mounting device according to an embodiment of the present invention. The storage mode refers to a state in which the mounting device (300) is almost fully stored inside the housing (200). At this time, a portion of the mounting part (344) may be exposed to the outside through an opening (201) formed on the upper surface of the housing, or the mounting part may be completely stored.

[0062] The mounting device (300) can be positioned so that the user can easily mount and operate the display device. Referring to FIG. 1, it can be seen that it is positioned at the armrest of a massage chair. This position can be designed with consideration that the display device is positioned at an appropriate distance and angle from the user to facilitate operation and viewing.

[0063] The display device may be configured to be placed on a stand (3441) included in the mounting portion (344). The stand (3441) may include a magnet (3442) to securely attach the display device, or may have a charging function to supply power to the display device.

[0064] In this way, the mounting device (300) can be stored inside the housing (200) when not in use to save space. Additionally, a mounting bracket (3441) included in the mounting portion (344) of the mounting device (300) can provide a position where the display device can be placed stably. The mounting bracket (3441) may include a magnet (3442) or a charging function, so that the display device can be stored and charged at the same time.

[0065] Hereinafter, the configuration of a mounting device according to an embodiment of the present invention will be described with reference to FIGS. 2 to 7.

[0066] FIG. 2 is a perspective view of a mounting device according to an embodiment of the present invention. FIG. 3 is an example of operation of a mounting device according to an embodiment of the present invention. FIG. 4 is a cross-sectional view of a first motor of a mounting device according to an embodiment of the present invention. FIG. 5 is a cross-sectional view of a first support tube of a mounting device according to an embodiment of the present invention. FIG. 6 is a cross-sectional view of a mounting portion of a mounting device according to an embodiment of the present invention. FIG. 7 is a diagram showing the operation method of a camera of a mounting device according to an embodiment of the present invention.

[0067] First, referring to FIG. 2, the mounting device (300) of the present invention may include components such as a first motor (310), a second motor (320), a third motor (330), a first support tube (341), a bent connecting part (342), a second support tube (343), and a mounting part (344). The housing (200) may be a component of the mounting device (300) or may be a separate component.

[0068] The housing (200) is formed as part of the main body (100) or as a case of the mounting device (300), and may serve to accommodate or protect the mounting device (300) inside. The housing (200) includes an opening (201) on its upper surface, and components of the mounting device may be exposed to the outside or housed through the opening (201).

[0069] The opening (201) may be formed in a shape such as a rectangle or a circle, and may be at a suitable location where the components of the mounting device (300) can move smoothly into and out of the housing (200). Preferably, the opening may be formed in the longitudinal direction of the first support tube (341) and may have a size or shape through which the second support tube (343) can pass completely.

[0070] The first support tube (341) can be mounted inside the housing (200) and serve as a main support structure for the mounting device (300). In one embodiment of the present invention, the first support tube (341) can be mounted inside the housing vertically to the ground.

[0071] The first support tube (341) can be withdrawn to the outside through the opening (201) during operation. That is, it is located inside the housing in storage mode, and can be withdrawn outside the housing in mounting mode or viewing mode.

[0072] At this time, the first motor (310) can transmit power to the first support tube (341) to operate it. The first motor (310) may be located adjacent to the first support tube (341). The first motor (310) can move the first support tube (341) up and down in a linear motion (see FIG. 3, z-direction). This will be described in detail later with reference to FIG. 3.

[0073] The bent connecting part (342) has an L-shape and can connect one end of the first supporting tube (341) and one end of the second supporting tube (343), respectively. The bent connecting part (342) supports the second supporting tube (343) which is positioned vertically on the first supporting tube (341), and can be configured to be operable so that the second supporting tube (343) can rotate at various angles.

[0074] The second support tube (343) can serve to adjust the position and orientation of the display device. The second support tube (343) is connected to the first support tube (341) through a bendable connecting part (342) and can rotate on a plane perpendicular to the first support tube (341) according to the operation of the second motor (320). At this time, the second motor (320) can rotate the first support tube (341) as an axis to rotate the bendable connecting part (342) and the second support tube (343) together. The second motor will be described later with reference to FIG. 5.

[0075] The mounting portion (344) is connected to the other end of the second support tube (343) to mount a display device. The mounting portion (344) includes a mounting stand (3441), and the mounting stand (3441) may include a magnet (3442) to stably attach the display device or provide a charging function. Additionally, the third motor (330) can adjust the angle of the display device by rotating the mounting stand (3441) around the second support tube (343) as an axis.

[0076] As described above, the present invention provides a mounting device that implements three degrees of freedom using three motors: a first motor (310), a second motor (320), and a third motor (330). The first motor (310) can control the linear motion of the first support tube (341) to adjust the height of the display device, and the second motor (320) can rotate the second support tube (343) around the first support tube (341) as an axis to adjust the direction of the display device. The third motor (330) can rotate the mounting base (3441) around the second support tube (343) as an axis to finely adjust the angle of the display device.

[0077] Referring to FIG. 3, the first support tube (341) can be rotated in the XY direction by the second motor (320). This operates by rotating the second support tube (343) on a horizontal plane (XY) with the first support tube (341) as an axis, and can be used to adjust the direction of the display device (D).

[0078] Additionally, the third motor (330) can rotate the stand (3441) in the YZ direction. Through this, the display device (D) can be tilted or angled accordingly and positioned in a direction suitable for the user's field of view.

[0079] This configuration using three motors can offer the advantage of a simpler structure and easier maintenance compared to complex robot devices that implement 6 degrees of freedom. At the same time, the position and orientation of the display device can be adjusted more flexibly than with a 2-degree-of-freedom device, enabling sufficient movement suitable for user requirements.

[0080] Accordingly, the present invention can provide a practical mounting device capable of efficiently adjusting a display device by combining appropriate simplicity and high flexibility. This allows the user to conveniently use the display device in various environments.

[0081] Hereinafter, with reference to FIGS. 3, 4, and 5, a mechanism for operating the first support tube (341) through the first motor (310) in a mounting device (300) according to one embodiment of the present invention will be described in detail.

[0082] Referring together with FIG. 3, a mounting device (300) according to one embodiment of the present invention may further include a fixed plate (311), a nut for a lead screw (3121), a lead screw (312), a limit switch (315), a guide rod (313), a guide plate (314), a gear set (321), a control unit (400), etc.

[0083] Referring to FIG. 3 and FIG. 4 together, the first motor (310) may be placed inside the housing (200) and configured to transmit rotational power to the lead screw (312). Referring to FIG. 4, rotational power from the first motor may be transmitted to the lead screw through gears. The lead screw (312) is in the form of a threaded rod and serves to convert rotational motion into linear motion.

[0084] Referring to FIG. 5, the fixed plate (311) can fix the first support tube (341) and the nut (3121) for the lead screw and support the linear movement of the lead screw (312). In addition, a second motor (320) can be installed on the fixed plate (311).

[0085] The first support tube (341) is installed inside the housing (200) vertically to the ground and may be fixed to the fixed plate (311) or positioned on the upper part of the fixed plate. The first support tube (341) is coupled with a lead screw (312) so that it can be drawn out from inside the housing to the outside or stored inside according to the operation of the first motor (310).

[0086] That is, the lead screw (312) is coupled with a nut (3121) for the lead screw fixed to the fixed plate (311), and when the lead screw rotates by the rotational power of the first motor (310), the nut (3121) for the lead screw can move in the vertical direction (Z direction). Accordingly, the fixed plate (311) fixedly coupled with the nut (3121) for the lead screw moves up and down, and the first support tube (341) installed on the fixed plate (311) moves up and down so that it can be withdrawn or stored inside the housing.

[0087] Additionally, a guide rod (313) and a guide plate (314) that guide and support a fixed plate (311) may be included to stabilize the linear motion direction of the first support tube (341).

[0088] The guide rod (313) is a rod-shaped structure positioned to move along the fixed plate (311) in a direction perpendicular to the ground, and can serve to support the linear movement of the fixed plate so that it can be performed stably without shaking.

[0089] The guide rod (313) is positioned parallel to the first support tube and can penetrate the fixed plate (314). Thus, the fixed plate moves up and down along the guide rod and can guide the direction of the lifting and lowering movement of the fixed plate.

[0090] The guide rod (313) can prevent instability of movement that may occur due to external impact or misalignment of the fixed plate.

[0091] The guide plate (314) is positioned parallel to the first support tube (341) and can guide the lifting and lowering movement of the fixed plate (311).

[0092] The guide plate (314) may be provided with a guide groove (3141) for restricting the movement path of the fixed plate (311). The guide groove (3141) may be designed so that the fixed plate (311) can move up and down stably along a designated path.

[0093] Additionally, a mounting device according to one embodiment of the present invention may include a sensing sensor for a mechanism to control a first motor. Referring to FIGS. 3 and FIGS. 5 together, the limit switch (315) is a type of sensing sensor for detecting the position of a fixed plate (311) and may be implemented in the form of a physical contact switch or a non-contact sensor.

[0094] A limit switch (315) is installed adjacent to the path along which the fixed plate (311) moves, and can generate a signal and transmit it to the control unit (400) when the fixed plate reaches the upper or lower limit position.

[0095] The upper limit switch (315a) operates when the fixed plate (311) reaches the upper limit position, allowing the control unit (400) to control the operation of the first motor (310) to stop or switch it to the opposite direction. The lower limit switch (315b) operates when the fixed plate (311) reaches the lower limit position, generating a signal in the same manner to control the operation of the first motor (310).

[0096] To this end, the control unit (400) that receives such a signal can control the operation of the first motor (310) based on the information detected by the limit switch (315).

[0097] The control unit (400) can control the operation of the mounting device (300) and perform the role of processing and transmitting signals for each component. The control unit can adjust the position and angle of the display device or control the state of the mounting device based on signals received from the motor (310, 320, 330) and the detection sensor (315).

[0098] The location of the control unit (400) may not be limited to a specific part and may be placed in a suitable location inside or outside the mounting device (300). This may be flexibly adjusted according to the design of the mounting device or the usage environment.

[0099] The control unit (400) can control the operation of the mounting device (300) by receiving an input signal from a user. The user can transmit a signal to the control unit through various input devices such as a remote control, a button, or a touch panel.

[0100] Additionally, the control unit (400) can process the received input signal to select one of the storage mode, mounting mode, and viewing mode, and can change the height of the first support tube (341) by operating the first motor (310) according to the selected mode.

[0101] For example, if the user selects storage mode, the control unit (400) can operate the first motor (310) to move the first support tube (341) into the housing (200). Conversely, if a mounting mode or viewing mode is selected, the control unit (400) can adjust the height of the first support tube (341) to a position desired by the user through the first motor (310).

[0102] The control unit (400) can control the movement of the first support tube (341) by referring to the signal of a sensing sensor, such as a limit switch (315), to perform this operation. Hereinafter, for convenience of explanation, the sensing sensor is assumed to be a limit switch in the description.

[0103] For example, while the first motor (310) moves the first support tube (341) into the housing (200) in storage mode, the lower limit switch (315b) can detect that the fixed plate (311) has reached the lower limit position and stop the operation of the first motor (310).

[0104] Likewise, in viewing mode, while the first motor (310) moves the first support tube (341) to the upper position, the upper limit switch (315a) or the third limit switch (not shown) can detect that the fixed plate (311) has reached the upper limit position and stop the operation of the first motor (310).

[0105] In another embodiment, the mounting mode may be a mode in which the first support tube (341) rises to an intermediate height inside the housing (200). In this mode, the display device can be placed in an appropriate position so that the user can conveniently mount the device.

[0106] The viewing mode may be a mode in which the first support tube (341) rises completely to the top, and in this state, the second motor (320) and the third motor (330) operate to rotate or adjust the angle of the display device to the user's field of view.

[0107] Additionally, the user can directly control the first motor (310) via a button or remote control to adjust the height of the first support tube (341). In this case, the control unit (400) receives a user input signal and, in cooperation with the limit switch (315), limits the movement range of the first support tube (341) and can operate to allow the user to accurately adjust it to a desired position.

[0108] Next, with reference to FIG. 5, details regarding the second motor (320) according to one embodiment of the present invention will be described in detail.

[0109] The second motor (320) can be installed on the fixed plate (311) and can rotate the second support tube (343) connected through the bent connecting part (342).

[0110] The second motor (320) can adjust the direction of the display device by rotating the second support tube (343) around the first support tube (341) as an axis. The second motor (320) is configured to operate to rotate the display device according to the user's position and requirements.

[0111] In practice, the second motor (320) can operate by rotating the first support tube (341) in place. As a result, the bent connecting part (342) connected to the first support tube (341) and the second support tube (343) rotate together, and the second support tube (343) can move on a plane perpendicular to the first support tube (341). For convenience of explanation, the second motor is described below as rotating the second support tube.

[0112] The second motor (320) may include a gear set (321), and this gear set may serve to transmit the rotational power of the second motor to the bent connecting part (342) and the second supporting tube (343).

[0113] The gear set (321) is connected to the first support tube (341) and can transmit the rotational power of the second motor (320) to the bent connecting part (342) and the second support tube (343). The gear set (321) is positioned on the outer surface of the first support tube (341) and can convert the rotational motion of the second motor (320) into an axis using the first support tube (341) to rotate the first support tube.

[0114] The gear set (321) can optimize and transmit rotational power according to the gear tooth profile and ratio, and can be designed to operate by tightly meshing between the second motor (320) and the first support tube (341). Additionally, the gear set (321) can transmit rotational force to the second support tube (343) through the bent connecting part (342), so that the second support tube rotates in a plane perpendicular to the first support tube.

[0115] Meanwhile, the control unit (400) can control the operation of the second motor (320). The control unit can control the second motor based on data collected from the camera (350), such as user input signals or tracking data, to rotate the second support tube (343). For example, the second motor can be used to adjust the second support tube (343) so that the display device fits exactly with the user's field of vision in viewing mode.

[0116] The second motor (320) is installed on the fixed plate (311) together with the first support tube (341) and can operate independently regardless of the operation of the first motor (310). This configuration allows the second motor (320) to operate independently and adjust the direction of the display device even while the first motor (310) moves the first support tube (341) up and down.

[0117] Next, referring to FIG. 6, the third motor (330) is installed in the mounting part (344) and can serve to adjust the angle of the display device. The third motor (330) rotates the mounting bracket (3441), which is part of the mounting part (344), around the second support tube as an axis, so that the display device can be adjusted to various angles.

[0118] The operation of the third motor (330) can be used to change the position of the display device so that it matches the user's field of view, or to fix it at a specific angle as needed.

[0119] Meanwhile, the mounting unit may include a magnet (3442) connected to the mounting bracket (3441) and an additional device for fixing the display device. The magnet (3442) serves to stably attach the display device, and the third motor (330) can rotate the display device to provide a viewing angle suitable for the user.

[0120] In another embodiment, the third motor (330) can rotate the mounting portion (344) around the second support tube (343). Alternatively, the third motor (330) can rotate the mounting bracket (3441) around the mounting portion (344) to adjust the angle of the display device more precisely.

[0121] The third motor (330) can be operated in connection with the control unit (400) and can operate based on a user's input signal or data collected from the camera (350). For example, if the user selects a viewing mode, the control unit can operate the third motor (330) to rotate the stand (3441) and adjust the angle of the display device to match the user's field of view.

[0122] Referring together with FIG. 7, the control unit (400) can control the operation of the third motor (330) and can adjust the position and angle of the display device based on the user's input signal or data collected from the camera (350).

[0123] The camera (350) is included in the mounting device (300) of the present invention and can take a picture of the user and automatically adjust the position and direction of the display device based on this. The camera (350) can be mounted on the second support tube (343) or the folded connecting part (342) and can be installed at an appropriate location to detect the user's position and posture in real time.

[0124] At this time, the user may refer to a user sitting on a functional furniture equipped with a housing having a mounting device according to one embodiment of the present invention, or a massage chair (10) as described above.

[0125] The camera (350) can be configured to transmit the captured image to the control unit (400) for analysis. The control unit (400) can track the user's face based on the data input from the camera (350) and adjust the display device to maintain an appropriate viewing angle with the user.

[0126] To this end, the control unit can operate the first motor (310), the second motor (320), and the third motor (330) to adjust the height, direction, and angle of the display device.

[0127] Additionally, the camera can provide data to optimize the position of the display device. When a user's face is detected, the control unit (400) can calculate the optimal position of the display device based on this and adjust the mounting device to move to that position.

[0128] The camera can be utilized in various operation modes. For example, in viewing mode, the camera can track the user's face position in real time whenever the user moves, allowing the display device to adjust to always align with the user's field of vision. Additionally, in storage mode, the camera's operation can be disabled, or it can serve the function of checking the storage status of the display device.

[0129] The operation of the camera (350) is controlled by the control unit (400) and can be activated or deactivated depending on the user's input signal or environmental conditions. Through this configuration, the camera provides data necessary to adjust the position and orientation of the display device and can support the mounting device (300) in implementing a user-customized viewing environment. This is merely an example, and the control unit may analyze the image captured by the camera to check the user's state and perform control accordingly.

[0130] Meanwhile, a mounting device (300) according to one embodiment of the present invention may include an encoder. In this case, an absolute encoder may be used. The absolute encoder (3444) may measure the position of the display device (D), convert it into a unique digital code, and provide it to the control unit (400). Referring together with FIG. 6, the encoder may be installed in the mounting unit (344).

[0131] The absolute encoder (3444) detects the position of the display device in real time and can be used to control the movement of each component of the mounting device in cooperation with the first motor (310), the second motor (320), and the third motor (330). For example, the encoder connected to the third motor (330) measures the rotation angle of the mounting bracket (3441), and the control unit (400) can rotate the mounting bracket (3441) based on this so that the display device aligns with the user's field of view.

[0132] The encoder can provide absolute position data that maintains current position information even when the power is turned off or the system is initialized. Through this, the control unit (400) can always recognize the current position of the display device and, if necessary, operate a motor to move the display device to a position desired by the user.

[0133] Additionally, the encoder can support an automatic adjustment function of the display device in conjunction with the camera (350). Based on data tracking the user's face, the control unit (400) can operate the motor using information transmitted from the encoder and move the display device to an optimal position and angle.

[0134] Absolute encoders can also be used to control the operating range of mounting devices. For example, the encoder can ensure safe operation by providing data to the control unit to prevent the movement of a display device from exceeding a set limit range.

[0135] FIG. 7 is a drawing for explaining face recognition using a camera (350) of a mounting device (300) and position adjustment of a display device (D) according to an embodiment of the present invention.

[0136] Referring to FIG. 7, the camera (350) may be mounted on the second support tube (343) or mounting part (344) and used to detect the user's face and adjust the position of the display device (D) based on this. The camera (350) may recognize the center of the user's face (A) and provide data to the control unit (400) so that the display device (D) aligns with the user's field of view based on that position.

[0137] Referring to FIG. 7, the camera (350) can calculate a specific target angle (θ_target) based on the position of the user's face center (A) and the display device (D). This angle is a value set so that the display device (D) is aligned with the user's gaze, and the control unit (400) can use this data to control the first motor (310), the second motor (320), and the third motor (330) to adjust the height, rotation direction, and angle of the display device (D).

[0138] Additionally, the camera continuously tracks the position of the display device (D) so that the display device (D) can be adjusted to align with the user's field of view even when the user moves. For example, if the user moves to the right, the camera (350) detects the new position (A') of the face, and the control unit (400) can operate a motor based on this to move the display device (D) to a new target position.

[0139] This operation ensures that the display device (D) always maintains an optimal viewing angle even when the user is in various postures or positions, and allows the mounting device (300) to be automatically adjusted. This can particularly support the convenient and effective use of the display device in functional furniture such as massage chairs or motion beds.

[0140]

[0141] Hereinafter, a mounting device according to another embodiment of the present invention will be described with reference to FIGS. 8 to 10. FIG. 8 shows functional furniture equipped with a mounting device according to another embodiment of the present invention. FIG. 9 is a mounting device according to another embodiment of the present invention. FIG. 10 is a rear perspective view of a mounting device according to another embodiment of the present invention.

[0142] A mounting device (300) according to another embodiment of the present invention can be mounted on functional furniture, and FIG. 8 illustrates a form mounted on a massage chair as an example. Here, functional furniture (10) may refer to a massage chair, a motion bed, or various furniture on which a user can sit or lie down.

[0143] The mounting device of the present embodiment includes not only a display device but also a camera (350) that detects the user's face and automatically adjusts the position of the display device accordingly.

[0144] The housing (200) is formed as a part of the main body (100) and serves as a case to protect the mounting device while also forming the outer structure of the main body.

[0145] In the embodiment illustrated in FIGS. 8 and 9, the first support tube (341) is mounted inside the housing (200), and the first motor (310) can operate by rotating the first support tube (341) to move it up and down, or to move it into or out of the housing.

[0146] The power connection part (316) is configured to transmit power by connecting the first motor (310) and the first support tube (341), and effectively transmits the rotational motion generated from the first motor (310) to the first support tube (341) so that the first support tube can rotate.

[0147] The first motor (310) can rotate the first support tube (341) on a vertical plane (XZ) centered on the other end of the first support tube (341). This rotational movement causes one end of the first support tube (341) to pass through an opening (201) formed on the upper surface of the housing (200), and allows a part of the first support tube (341) to be drawn out to the outside or stored inside the housing through the opening.

[0148] In this process, the rotation of the first support tube (341) can rotate the bent connecting part (342) and the second support tube (343) together, thereby allowing the display device (D) to be adjusted to an appropriate position and direction according to the user's location and requirements. In particular, the method of rotating the first support tube (341) can simplify the structure compared to the vertical movement method, and can provide mechanical stability while increasing space utilization.

[0149] In this embodiment, the camera (350) may be mounted on the second support tube (343) or the folded connecting part (342), and can detect the user's face in real time and adjust the position of the display device based on this. The control unit (400) can analyze the data received from the camera (350) and operate the second motor (320) and the third motor (330) so that the display device aligns with the user's field of view.

[0150] Unlike the vertical movement method shown in FIG. 1, in this embodiment, the mounting device can be moved into or out of the housing (200) by using a method of rotating the first support tube (341). This configuration allows the display device to be adjusted to a desired position while simplifying the structure of the mounting device and maximizing space utilization.

[0151] Referring to FIGS. 8 and 9, a mounting device (300) according to another embodiment of the present invention includes a first support tube (341), a second support tube (343), and a mounting bracket (3441), and each component can be adjusted in various directions by the operation of a motor.

[0152] The first support tube (341) can be rotated in the XY direction by the second motor (320). This operates by rotating the second support tube (343) on a horizontal plane (XY) with the first support tube (341) as an axis, allowing the direction of the display device (D) to be adjusted according to user requirements.

[0153] For example, when a mounting device is introduced into the housing (200), the control unit (400) can control the second motor (320) so that the second support tube (343) is positioned on the vertical plane (XZ).

[0154] Additionally, the third motor (330) can rotate the stand (3441) in the YZ direction. This allows the display device (D) to be tilted or angle-adjusted on the vertical plane (YZ) so as to be positioned to match the user's field of view.

[0155] That is, in another embodiment of the present invention, the mounting device (300) can be moved into or out of the housing (200) by the first motor (310) rotating the first support tube (341).

[0156] When storing, the second motor (320) rotates the second support tube (343) so that it aligns with the vertical plane (XZ) on which the first support tube (341) rotates, and then the first motor (310) rotates the first support tube (341) into the housing (200). When withdrawing, this process is performed in reverse order to expose the mounting device to the outside.

[0157] Other details regarding configuration and operation are the same as those described in FIGS. 1 to 7 above, so a repetitive explanation will be omitted.

[0158] Referring together with FIG. 10, the mounting device (300) of the present invention may be configured with a hollow structure designed to form a space inside the first support tube (341), the second support tube (343), and the mounting part (344) to accommodate a cable (360). The hollow structure prevents the cable (360) from being exposed to the outside, thereby keeping the appearance of the mounting device simple.

[0159] This hollow structure allows the cable (360) to be efficiently arranged along the interior, and enables the safe and smooth transmission of power and signals. Through this, the power supply and control signal transmission required for the operation of the display device (D) can be stably carried out.

[0160] In particular, the hollow structure can serve to protect the cable (360) from being obstructed or damaged by the movement of the device even during the operation of the mounting device (300). For example, the cable (360) can be stably maintained even when the first support tube (341) rotates or the second support tube (343) rotates.

[0161] That is, the cable (360) can be installed by penetrating the first support tube (341), the second support tube (343), and the mounting part (344), thereby effectively performing power supply and control signal transmission.

[0162] As described above, the present invention relates to a 3-degree-of-freedom mounting device (300) that can adjust the position and orientation of a display device (D) to suit user requirements.

[0163] The mounting device of the present invention operates the first support tube (341), the second support tube (343), and the mounting part (344) through the first motor (310), the second motor (320), and the third motor (330), and can position the display device (D) at a desired position and angle.

[0164] The present invention enables sufficient movement in a simple structure using only three motors, making maintenance easy and reducing manufacturing costs.

[0165] FIG. 11 is a block diagram illustrating a mounting device according to an embodiment of the present invention.

[0166] A massage chair according to one embodiment of the present invention includes a mounting device (300), a camera (350), a control unit (400), a sensor unit (500), a memory (600), and the like. Of course, deleting, changing, or adding some modules as needed by those skilled in the art is also within the scope of the present invention.

[0167] According to an embodiment of the present invention, a massage chair (10) can perform a massage operation of a preset mode or a mode selected by the user while the user is seated. The massage chair (10) can directly apply mechanical stimulation to the body of the seated user by tapping, pressing, kneading, pulling, or moving the body of the seated user. The massage chair (10) can massage one or more of the head, back, arms, buttocks, and legs of the seated user.

[0168] For example, the massage chair (10) may include an airbag (not shown), and the massage chair (10) may perform a massage operation that repeats compression and relaxation on a part of the user's body by adjusting the air pressure of the airbag.

[0169] A mounting device (300) may be provided in a massage chair (10). The mounting device (300) may perform the operation of adjusting the position of a camera (350) for user face recognition under the control of a control unit (400).

[0170] The mounting device (300) can perform the operation of adjusting the position of the display device under the control of the control unit (400).

[0171] At this time, the position for adjusting the position of the camera (350) placed on the mounting device (300) and the position for performing the operation of adjusting the position (D) of the display device can be controlled by the control unit (400) to be described later.

[0172] The camera (350) can capture the surrounding environment of the mounting device (300) and convert it into an electrical signal. The image captured by the camera (350) and converted into an electrical signal is stored in the memory (600) and can then be used to recognize the user through the control unit (400).

[0173] Additionally, the camera (350) may have a field of view. In this case, the field of view refers to an area where, for example, a user's face located around the camera (350) can be detected. The camera (350) can detect only the user's face located within the field of view. When the user's face is located within the field of view of the camera (350), the mounting device (300) can determine the position of the user's face. Additionally, the camera (350) can detect the angle between the display device (D) and the user's face.

[0174] The camera (350) may be installed so as to be angle-adjustable relative to the mounting device (300). In this case, there is an advantage in that angle adjustment for photographing the user's face is easy.

[0175] Alternatively, in a possible embodiment, the camera (350) may be built into the mounting device (300) and configured so that only the lens of the camera (350) is exposed.

[0176] The camera (350) can capture an image of the user's face in real time. The camera (350) can transmit the captured image of the user's face to the control unit (400) via communication. At this time, the communication may be, for example, serial communication.

[0177] The control unit (400) may include all types of devices capable of processing data, such as a processor. Here, 'processor' may refer to a data processing device embedded in hardware that has a physically structured circuit to perform functions expressed by code or instructions included in a program, for example. Examples of such data processing devices embedded in hardware may include a microprocessor, a central processing unit (CPU), a processor core, a multiprocessor, an application-specific integrated circuit (ASIC), a field programmable gate array (FPGA), etc., but the scope of the present invention is not limited thereto.

[0178] The control unit (400) is a type of central processing unit that can control the entire operation related to the massage chair (10) by running control software loaded in the memory (600).

[0179] The control unit (400) can control the massage chair (10) to control the start, change, and end of the massage operation.

[0180] The control unit (400) may further include an operation unit (not shown) that receives input from a user and transmits it to the control unit (400).

[0181] An operating unit (not shown) among the control unit (400) may be equipped with a plurality of operating buttons and may transmit a signal corresponding to an input button to the control unit (400). Such an operating unit (not shown) may be composed of a sensor, button, or switch structure capable of recognizing a user's touch or press operation.

[0182] When the control unit (400) receives a signal corresponding to the control of the mounting device (300) among the buttons of the operation unit, it can set the mounting device (300) to a manual operation state. For example, the manual operation state can receive the three degrees of freedom of motion of the mounting device (300) and adjust the position and direction of the display device (D).

[0183] The control unit (400) can recognize the user's facial expression and changes in facial expression through the image transmitted by the camera (350).

[0184] For example, the control unit (400) can recognize the user's face before the massage chair (10) performs a massage operation. Additionally, the control unit (400) can capture an image of the user's face while the massage chair (10) performs a massage operation.

[0185] The control unit (400) can receive a user's face image in real time by communicating with the camera (350).

[0186] The control unit (400) can identify the user by applying an image analysis algorithm to the user's face image received in real time.

[0187] The control unit (400) can recognize the user's face using the camera (350) and recognize the coordinates of the face. The control unit (400) can determine the user's facial expression based on the coordinates of the user's face.

[0188] For example, the control unit (400) may include an image processing application that analyzes a captured face image. The image processing application may apply an artificial intelligence algorithm to the captured image and determine the user's facial expression appearing in the image as one of a plurality of predefined facial expressions. In this case, an expression recognition model of the open source OpenCV Python library may be used as the image processing application. In an embodiment of the present invention, an OpenCV expression recognition model that outputs a point coordinate system for a person's facial expression may be applied.

[0189] Meanwhile, the control unit (400) can determine the position of the user's face based on a distance value received through a distance measuring sensor included in the sensor unit (500). At this time, the distance measuring sensor may be a time-of-flight sensor (TOF) sensor, and the TOF value can be measured as a distance value through the TOF sensor.

[0190] For example, the control unit (400) can determine the position of the user's face using a plurality of distance measurement values ​​corresponding to a plurality of points obtained through a distance measuring sensor, and can determine the user's facial expression by recognizing the user through image processing of the plurality of distance values ​​corresponding to the position of the user's face. According to an embodiment, image processing can be performed using a low-cost microcomputer.

[0191] The control unit (400) can determine the state of the user based on the recognized facial expression of the user.

[0192] The sensor unit (500) may include at least one sensor, and includes sensing means such as a distance measuring sensor, a gravity sensor, a geomagnetic sensor, a motion sensor, a gyroscope sensor, an accelerometer sensor, an inclination sensor, a depth sensor, a pressure sensor, a touch sensor, etc.

[0193] At this time, the sensor unit (500) is designed to detect the state in which a user is seated on the aforementioned massage chair (10).

[0194] The memory (600) stores various information required for the function of the control unit (400) (e.g., image capture cycle, etc.) and may include a volatile or non-volatile recording medium. The memory (600) may include a magnetic storage medium or a flash storage medium, but the scope of the present invention is not limited thereto. Such memory (600) may include internal memory and / or external memory, and may include a volatile memory such as DRAM, SRAM, or SDRAM, a non-volatile memory such as OTPROM (one time programmable ROM), PROM, EPROM, EEPROM, mask ROM, flash ROM, NAND flash memory, or NOR flash memory, a flash drive such as an SSD, CF (compact flash) card, SD card, Micro-SD card, Mini-SD card, Xd card, or memory stick, or a storage device such as an HDD.

[0195] In addition, the memory (600) has the function of storing images captured by the camera (350), as well as the function of storing user information based on the stored images, and the function of storing all or part of the result of performing a service on the massage chair (10).

[0196] And, the control unit (400) can control the position of the mounting device (300) to use the massage chair (10).

[0197] For example, the control unit (400) can control the position of the mounting device (300) to check the user's face through the camera (350).

[0198] The control unit (400) can control the starting position of the mounting device (300) based on the angle of the massage chair (10). At this time, the starting position of the mounting device (300) may be a position set corresponding to the angle of the massage chair (10) stored in the memory (600).

[0199] The control unit (400) can control the mounting device in response to the operation mode of the massage chair (10).

[0200] The control unit (400) can detect errors while the massage chair (10) is operating. If the control unit (400) detects a proximity safety function error, an overload error, or a rotation error, the massage chair (10) can be changed to a safety mode.

[0201] Specifically, the control unit (400) can determine that there is a proximity safety function error when the user of the massage chair (10) comes within a certain distance of the mounting device.

[0202] The control unit (400) can receive the motor load current of the mounting device (300). The control unit (400) can determine that an overload error has been detected when the motor load current reaches an inflection point.

[0203] The control unit (400) can determine that a rotation error has been detected when a sensor value of a rotation sensor is received while moving the mounting device up and down and / or left and right.

[0204] Additionally, the control unit (400) can recognize the user based on the user's face image and recommend a massage course based on the recognized user's face information. Specifically, the control unit (400) can recommend a massage course based on the user's condition.

[0205] For example, the control unit (400) can set a massage course based on the age, gender, usage time, etc. of each user stored in the memory (600).

[0206] The control unit (400) can control the massage chair (10) to change the massage operation based on the recognition result of the facial expression of the user using the massage service.

[0207] According to the present invention, since the massage operation is configured to be changed based on the result of recognizing the user's facial expression, there is an advantage that the massage intensity can be changed without separate operation or change of posture by the user.

[0208] From now on, with reference to the drawings 12 and below, the recognition of a user's facial expression performed by the massage chair (10) described above and the control of the operation change of the massage chair (10) and the mounting device (300) according to the same will be explained in detail.

[0209] FIG. 12 is a flowchart of the operation of a massage chair control method according to an embodiment of the present invention.

[0210] Referring to FIG. 12, the massage chair control method may first perform a step (S110) of detecting whether a user is seated. Various sensors and methods may be performed to determine whether a user is seated in the massage chair (10). More specifically, a control unit (400) may determine whether a user is seated by receiving a pressure signal corresponding to the user's seating from a pressure sensor placed in the massage chair (10).

[0211] After the above step S110, the massage chair control method may perform a position adjustment step (S120) of the mounting device (300).

[0212] Various sensors and methods for adjusting the position of the mounting device (300) may be performed. More specifically, the control unit (400) can adjust the position of the mounting device (300) so that when a user sits on the massage chair (10), the user can look at the display device (D) mounted on the mounting device (300).

[0213] For example, the position of the mounting device (300) can be set to a position favorable for the user sitting in the massage chair (10) to view the video output from the display device (D). That is, the position of the mounting device (300) can be adjusted so that the display device (D) is positioned in the user's frontal line of sight.

[0214] For example, the control unit (400) can adjust the position of the mounting device (300) by recognizing the user's face through the camera (350). When the mounting device (300) moves forward of the user seated in the massage chair (10), the control unit (400) can adjust the position of the mounting device (300) so that the camera (350) can recognize the face of the user seated in the massage chair (10).

[0215] Meanwhile, the control unit (400) can adjust the position of the mounting device (300) based on the angle of the massage chair (10). Since the position of the seated user's face changes according to the angle of the massage chair (10), the position of the mounting device (300) can be set to a position favorable for looking at the display device (D). The control unit (400) can receive the position of the mounting device (300) set according to the angle of the massage chair (10) from the memory (600). Specifically, the control unit (400) can adjust the position of the mounting device, which is stored in the memory (600), in correspondence with the backrest angle provided in the massage chair (10).

[0216] After the above step S120, the massage chair control method may perform a user face verification step (S130).

[0217] Various sensors and methods for verifying a user's face can be implemented. More specifically, the control unit (400) can verify the user's face based on user recognition information.

[0218] For example, the control unit (400) can recognize coordinates from the user's face recognized through the camera (350). Subsequently, the control unit (400) can recognize the user's facial expression based on the coordinates of the user's face.

[0219] Meanwhile, the control unit (400) can determine the position of the user's face by receiving distance information between the mounting base of the mounting device (300) and the user's face from a distance measuring sensor placed in the mounting device (300).

[0220] For example, the control unit (400) can determine the overall position of the face using a distance measuring sensor and identify the user and recognize the user's state through image processing.

[0221] After the above step S130, the massage chair control method may perform a user massage course recommendation step (S140).

[0222] Various methods can be performed to recommend a massage course to the user. More specifically, the control unit (400) can recommend a massage course that the user has mainly used based on a massage course previously used by the user.

[0223] The control unit (400) can recommend a massage course based on the user's age, gender, etc.

[0224] The control unit (400) can select and provide one of a plurality of massage courses entered by the user through the control unit (not shown).

[0225] After the above step S140, the massage chair control method may perform a step (S150) of recognizing the user's facial expression during the massage operation time and controlling the massage operation to change.

[0226] More specifically, the camera (350) can capture an image of the user's face in real time, and the control unit (400) can receive the captured image of the user's face.

[0227] Afterwards, the control unit (400) can recognize an expression in the user's face image and control the massage operation of the massage chair (10) based on the recognized expression.

[0228] FIG. 13 is a flowchart illustrating a method for recommending massage actions based on user recognition according to an embodiment of the present invention.

[0229] Referring to FIG. 13, the control unit (400) can receive a user face image acquired by the camera (350) (S210).

[0230] After the above step S210, the control unit (400) can recognize the user's face from the captured face image (S220). Specifically, the control unit (400) can capture a face image from the user's face image, analyze the captured face image to obtain coordinate information, and recognize the user based on the obtained coordinate information.

[0231] After step S220 above, the control unit (400) can determine whether the recognized user face is a registered user (S230). The registered user may be user face information already stored in memory (600).

[0232] After the above step S230, if the recognized user face is not a registered user, the control unit (400) can perform user registration based on the recognized user face. Specifically, the control unit (400) can store an image captured from the user's face image as user face information in the memory (600) (S235).

[0233] Meanwhile, after the above step S230, if the recognized user face is that of a registered user, the control unit (400) can recommend a customized massage course based on user information already stored in the memory (600) (S240). Specifically, the control unit (400) can analyze the user's service usage pattern based on the user's service usage information stored in the memory. The control unit (400) can provide a massage course corresponding to the user's recognition information based on the registered user's service usage pattern. At this time, the service usage information may include usage time, the user's age, the user's gender, etc.

[0234] For example, the control unit (400) can classify usage time into morning and afternoon, analyze the user's usage pattern, and store it in memory (600).

[0235] The control unit (400) can set a massage course such as "10-minute morning wake-up" as the massage course based on registered user information when the user's usage time is in the morning. The control unit (400) can set a massage course such as "30-minute TV viewing course" as the massage course when the user's usage time is 8:00 PM.

[0236] And, the control unit (400) can receive interaction with user recognition and provide a customized massage course to the user through conversation with the user.

[0237] FIG. 14 is a flowchart illustrating a method for controlling a mounting device based on user recognition according to an embodiment of the present invention.

[0238] Referring to FIG. 14, when the massage chair (10) provides a massage course to the user, the control unit (400) can activate (ON) the tracking mode of the massage chair (10) (S310). Specifically, the user can turn the tracking mode On / Off through an operating unit (not shown). When in tracking mode, the control unit (400) moves the mounting device for a preset time and then receives the user's face image through the camera (350). Then, when the camera (350) moves beyond a preset angle in response to the user's movement in tracking mode, the control unit (400) can switch to a slim mode in which the tracking mode is activated and the tracking stops after a preset time. At this time, the time for moving the mounting device may be set to 3 seconds, but is not limited thereto.

[0239] After step S310 above, if the tracking mode is activated, the control unit (400) can determine whether to recognize the user's face (S320). Specifically, the control unit (400) can recognize the user's face through the image of the user's face received through the camera (350) or through the location information of the user's face received through the distance measuring sensor.

[0240] After the above step S320, if the control unit (400) recognizes the user face (YES of S320), it can determine the location of the user face (S330).

[0241] After step S330 above, the control unit (400) can determine whether the user's face is close to the mounting device based on the determined position of the user's face (S340). That is, the control unit (400) can determine whether the position of the user's face is located within a preset distance from the mounting device. Specifically, the control unit (400) can determine whether the user's face is located within a preset distance from the camera (350) based on coordinate values ​​in the image of the user's face through the camera (350), or determine whether the user's face is located within a preset distance from the distance measuring sensor based on the distance value from the user received through the distance measuring sensor.

[0242] After step S340 above, if the user's face is close to the mounting device (YES of S340), the control unit (400) can change the massage chair (10) to safety mode (S350).

[0243] After step S350 above, if the massage chair (10) is changed to a safety mode, the control unit (400) can control the mounting device (400) to move in response to the safety mode (S360). That is, if the position of the user's face is within a preset distance from the mounting device, the position of the mounting device can be changed. Specifically, the control unit (400) can control the mounting device by receiving the position of the mounting device (400) corresponding to the safety mode from the memory (600). The position of the mounting device (400) corresponding to the safety mode can be set to a position spaced apart from the user by a preset distance so that the user seated in the massage chair (10) can easily get up from the massage chair (10).

[0244] Meanwhile, after step S320, if the control unit (400) fails to recognize the user's face (NO of S320), the control unit (400) may change the massage chair (10) to a safe mode (S350). Subsequently, when the massage chair (10) is in a safe mode and the user stands up from the massage chair (10), the control unit (400) may change the massage chair (10) from a safe mode to a standby mode. Subsequently, when the user sits on the massage chair (10), the control unit (400) may change the massage chair (10) from a standby mode to a usage mode for use.

[0245] FIG. 15 is a flowchart illustrating a method for controlling a massage device based on user recognition according to an embodiment of the present invention.

[0246] Referring to FIG. 15, when the massage chair (10) provides a massage course to the user, the control unit (400) can activate (ON) the tracking mode of the massage chair (10) (S410).

[0247] After step S410 above, if the tracking mode is activated, the control unit (400) can receive an image of the user's face (S420).

[0248] After step S420 above, the control unit (400) can analyze the user's facial expression based on an image of the user's face (S430). Specifically, the control unit (400) can apply an artificial intelligence algorithm to an image of a face captured at a preset interval and determine the user's facial expression shown in the image as one of a plurality of preset facial expressions. For example, an expression recognition model of the open source OpenCV Python library can be used as an image processing application. The control unit (400) can apply an OpenCV expression recognition model that classifies human facial expressions into seven categories: Angry, Disgusting, Fearful, Sad, Neutral, Surprising, and Happy.

[0249] After step S430 above, the control unit (400) can determine the user's condition based on the user's facial expression (S440). For example, the control unit (400) can determine the user's level of fatigue, level of pain, and level of drowsiness based on the user's facial expression.

[0250] After step S440 above, the control unit (400) can control the massage operation to change in response to the user's state (S450). For example, if the user is in a drowsy state, the control unit (400) can move the position of the mounting device in response to the slim mode, reduce the sound generated by the massage chair (10), or output a song optimized for the user to sleep. Additionally, the control unit (400) can activate other functions corresponding to the slim mode by linking the massage chair (10) with IT equipment.

[0251] For example, if the user is in a painful state, the control unit (400) can check the degree of pain according to facial expressions and reduce the intensity of the massage or recommend changing the massage course.
