Description

Mounting device

[0001] The present invention relates to a mounting device, and more specifically, to a 3-degree-of-freedom mounting device that is mounted on a motion chair, etc., and can track and operate the user's movements.

[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 issues 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.

[0015] The problems to be solved by the present invention are not limited to the technical problems mentioned above, and other technical problems not mentioned will be clearly understood by those skilled in the art to which the present invention belongs from the description below.

[0016] For the above purpose, a mounting device according to one embodiment of the present invention comprises: a housing having an opening on its upper surface; a first support tube mounted inside the housing; an L-shaped bent connecting part with one end connected to one end of the first support tube; a second support tube with one end connected to the other end of the bent connecting part and connected vertically to the first support tube; a mounting part including a mounting stand connected to the other end of the second support tube and on which a display device is mounted; a first motor for pulling the first support tube out of the opening; a second motor for rotating the second support tube on a plane with the first support tube as an axis; a third motor for rotating the mounting stand with the second support tube as an axis; and a control unit for controlling the first motor, the second motor, and the third motor.

[0017] The first support tube is mounted vertically to the ground inside the housing, and the first motor can move the first support tube up and down linearly.

[0018] The apparatus further includes a fixed plate to which the first support tube and the second motor are fixed; a nut for a lead screw fixed to the fixed plate; and a lead screw engaged with the nut for the lead screw and connected to the first motor; wherein the first motor transmits rotational power to the lead screw to move the nut for the lead screw up and down, thereby causing the first support tube to move up and down.

[0019] It may further include a guide rod arranged parallel to the first support tube and penetrating the fixed plate to guide the direction of the lifting movement of the fixed plate; and a guide plate arranged parallel to the first support tube and having a guide groove for guiding the lifting movement of the fixed plate.

[0020] The control unit further includes at least one sensing sensor located adjacent to the path where the fixed plate moves and detects the height of the fixed plate, and the control unit can control the first motor based on the height information detected by the at least one sensing sensor.

[0021] The above control unit receives one of a storage mode, a mounting mode, or a viewing mode, and can change the height of the first support tube based on the received mode.

[0022] The first motor can rotate the first support tube on a vertical plane around the other end of the first support tube to pass through the opening.

[0023] When the control unit is drawn into the housing, it can control the second motor so that the second support tube is positioned on the vertical plane.

[0024] The device further includes a camera mounted on the second support tube or the folded connecting part to capture an image of a user sitting on the functional furniture on which the housing is mounted, and the control unit tracks the user's face using the camera, analyzes the image captured by the camera to calculate the optimal position of the display device based on the analysis, and controls the first motor, the second motor, or the third motor to move the display device to the optimal position.

[0025] The above mounting part may include an absolute encoder that converts the position of the above mounting part into a unique code value.

[0026] The above mounting portion may include a magnet to which the display device is attached.

[0027] It further includes a cable that supplies power, and the first support tube, the second support tube, or the mounting part is configured with a hollow structure, and the cable can penetrate the first support tube, the second support tube, or the mounting part.

[0028] According to one embodiment of the present invention, the height, direction, and angle of the display device can be adjusted through three motors, thereby providing a viewing environment that meets user requirements.

[0029] In addition, it supports various operation modes such as storage mode, stand mode, and viewing mode, allowing the display device to be stored inside the housing or placed in an optimal position as needed.

[0030] In addition, the position of the display device can be automatically adjusted using a camera and an absolute encoder, enabling a personalized viewing experience.

[0031] Further scopes of the applicability of the present invention will become apparent from the following detailed description. However, since various changes and modifications within the spirit and scope of the present invention are clearly understood by those skilled in the art, specific embodiments, such as the detailed description and preferred embodiments of the present invention, should be understood as being given merely as examples.

[0050] FIG. 1 shows functional furniture equipped with a mounting device according to one embodiment of the present invention.

[0051] 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.

[0052] 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.

[0053] For convenience of explanation, this specification describes the case where the mounting device of the present invention is mounted on a massage chair.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] 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.

[0058] 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.

[0059] 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.

[0060] 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.

[0061] 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.

[0062] 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.

[0063] 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.

[0064] 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.

[0065] 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).

[0066] 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.

[0067] 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.

[0068] 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.

[0069] 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.

[0070] 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.

[0071] 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 folded 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 folded connecting part (342) and the second support tube (343) together. The second motor will be described later with reference to FIG. 5.

[0072] 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.

[0073] 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.

[0074] 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).

[0075] 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.

[0076] 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.

[0077] 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.

[0078] 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.

[0079] 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.

[0080] 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.

[0081] 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).

[0082] 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).

[0083] 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.

[0084] 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).

[0085] 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.

[0086] 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.

[0087] The guide rod (313) can prevent instability of movement that may occur due to external impact or misalignment of the fixed plate.

[0088] 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).

[0089] 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.

[0090] 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.

[0091] 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.

[0092] 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).

[0093] 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).

[0094] 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).

[0095] 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.

[0096] 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.

[0097] 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.

[0098] 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).

[0099] 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.

[0100] 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).

[0101] 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).

[0102] 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.

[0103] 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.

[0104] 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.

[0105] 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.

[0106] 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).

[0107] 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.

[0108] 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.

[0109] 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).

[0110] 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.

[0111] 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.

[0112] 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.

[0113] 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.

[0114] 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.

[0115] 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.

[0116] 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.

[0117] 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.

[0118] 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.

[0119] 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).

[0120] 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.

[0121] 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.

[0122] 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.

[0123] 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.

[0124] 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.

[0125] 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.

[0126] 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.

[0127] 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).

[0128] 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.

[0129] 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.

[0130] 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.

[0131] 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.

[0132] 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.

[0133] 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.

[0134] 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).

[0135] 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.

[0136] 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.

[0137]

[0138] 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.

[0139] 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.

[0140] 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.

[0141] 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.

[0142] 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.

[0143] 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.

[0144] 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.

[0145] 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.

[0146] 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.

[0147] 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.

[0148] 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.

[0149] 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.

[0150] 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).

[0151] 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.

[0152] 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).

[0153] 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.

[0154] 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.

[0155] 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.

[0156] 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.

[0157] 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.

[0158] 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.

[0159] 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.

[0160] 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.

[0161] The present invention enables sufficient movement in a simple structure using only three motors, making maintenance easy and reducing manufacturing costs.
