[0020] FIG. 1 is a front view illustrating an upper body exercise assistance device according to one embodiment, and FIG. 2 is a front view illustrating a user wearing the upper body exercise assistance device according to one embodiment. FIG. 3 is a side view illustrating a user wearing the upper body exercise assistance device according to one embodiment, and FIG. 4 is a front view illustrating the interior of a housing, a communication unit, a housing motor, a connection frame, an IMU sensor, and a handle according to one embodiment.

[0021] Referring to FIGS. 1 to 4, the upper body exercise assistance device (1) is worn on the user's lower arm and can assist the user's upper body exercise. In the drawings of this specification, the upper body exercise assistance device (1) is depicted as being worn on the user's right arm, but alternatively, the upper body exercise assistance device (1) can also be worn on the user's left arm. In this case, the shape of the upper body exercise assistance device worn on the left arm can be understood to be symmetrical to the shape of the upper body exercise assistance device (1) worn on the right arm.

[0022] In one embodiment, the upper body movement assistance device (1) can support the user's wrist and palm so that the user's hand does not move relative to the lower arm. Here, the hand refers to the organ attached to the front of the wrist, which is composed of the palm, the back of the hand, and the fingers, and the lower arm refers to the area from the elbow to the wrist. When the upper body movement assistance device (1) is worn, the flexion, extension, radial deviation, and ulnar deviation of the user's wrist are restricted, and the user's hand can move in the same direction as the lower arm.

[0023] In one embodiment, the upper body exercise assistance device (1) can be connected to any device for assisting the user's upper body exercise. For example, the upper body exercise assistance device (1) can be connected to a cable, an elastic band, etc. to assist the user's resistance exercise. The upper body exercise assistance device (1) can prevent the user's wrist from being excessively bent during resistance exercise. Here, resistance exercise refers to an exercise that stimulates the muscles of the target upper body part, such as the chest, back, and waist, by using tension while repeatedly pulling and releasing a cable or an elastic cable connected to a weight plate.

[0024] In one embodiment, the upper body exercise assistance device (1) is provided as a pair and can assist resistance exercise of the user's right and left arms, respectively, via a pair of cables provided on the wearable robot. Here, the wearable robot can be an exercise device that can be worn on the user's upper body and has a motor that can wind or unwind the cables. By controlling the rotation of the motor, the intensity of the resistance exercise can be adjusted.

[0025] In one embodiment, the upper body exercise assistance device (1) can be used as an exercise game controller. When the user moves the arm on which the upper body exercise assistance device (1) is worn, sensors or the like placed on the upper body exercise assistance device (1) can recognize the user's motion. Buttons, switches, or the like for game progression may be additionally placed on the upper body exercise assistance device (1). Since the user moves not only the wrist but also the entire arm, the user's movements can be expanded and the exercise effect can be enhanced.

[0026] In one embodiment, the upper body exercise assistance device (1) can provide information about the exercise by transmitting vibration to the user's lower arm. For example, when the user completes the motion of pulling and releasing a cable, the vibration of the upper body exercise assistance device (1) can be transmitted to the user. The user can recognize that the number of exercise times has been counted through the vibration. If the vibration of the upper body exercise assistance device (1) is not transmitted to the user even after the motion of pulling and releasing the cable has been completed, the user can recognize that the exercise posture is incorrect. The upper body exercise assistance device (1) can include a housing (11), a communication unit (12), a housing motor (13), a strap (14), a connecting frame (15), a handle (16), and an IMU (inertia measurement unit) sensor (17).

[0027] In one embodiment, the housing (11) may be placed on the user's forearm. For example, the housing (11) may be placed on the user's wrist. The housing (11) may be secured to the user's forearm by a strap (14). A communication unit (12), a housing motor (13), and an IMU sensor (17) may be placed on the housing (11).

[0028] In one embodiment, the communication unit (12) may be positioned inside or outside the housing (11). The housing motor (13) may receive a signal from the communication unit (12) and generate vibration. The vibration generated by the housing motor (13) may be transmitted to the user through the user's skin. The housing motor (13) may be positioned inside the housing (11) to be protected from external impact or foreign substances. Alternatively, the housing motor (13) may be positioned outside the housing (11) to transmit stronger vibration to the user's lower arm.

[0029] In one embodiment, the IMU sensor (17) can measure the rate of change, displacement, etc. for the user's posture transformation and position movement. Since the user's hand moves in unison with the forearm, unlike as illustrated in FIG. 4, the IMU sensor (17) may be placed on the handle (16) rather than the housing (11). The measurement values ​​detected by the IMU sensor (17) may be transmitted to the communication unit (12). The communication unit (12) may control the vibration of the housing motor (13) based on the measurement values ​​transmitted from the IMU sensor (17). The communication unit (12) may also receive the measurement values ​​detected by the tension sensor (18) through a wire (W).

[0030] In one embodiment, the strap (14) may be connected to the housing (11) and worn on the user's forearm. For example, one end of the strap (14) may be provided with a male Velcro, and the other end may be provided with a female Velcro. The male Velcro and the female Velcro may be provided on different sides of the strap (14) so ​​as to wrap around the user's wrist and then be connected to each other.

[0031] In one embodiment, a connecting frame (15) may extend from the housing (11). The connecting frame (15) may be formed of a lightweight and rigid material. The connecting frame (15) may be formed integrally with the housing (11). A handle (16) may be connected to the housing (11) via the connecting frame (15). The handle (16) may not move relative to the housing (11).

[0032] In one embodiment, the connecting frame (15) may have a shape that is bent toward the user's palm. Unlike the present invention, if the connecting frame (15) is not bent but extends in a vertical direction from the housing (11), the distance between the handle (16) and the user's palm may increase. Here, the vertical direction is the +z direction based on FIG. 3. In this case, the user must bend his / her wrist to grip the handle (16), and if the user holds the handle (16) for a long time, the wrist may be strained. By having the connecting frame (15) have a bent shape, the degree of wrist bending when gripping the handle (16) is reduced, and the wearing comfort of the upper body exercise assistance device (1) can be improved.

[0033] In one embodiment, the handle (16) may be provided diagonally on a plane facing the user's palm. The handle (16) may extend from the connecting frame (15) in the +y direction and also in the +z direction. Unlike the present invention, if the handle (16) extends only in the +y direction, which is parallel to the strap (14) rather than diagonally, the user may only use the thenar eminentia to grip the handle (16). Since the handle (16) is provided diagonally as in the present invention, the user may use the hypothenar eminentia as well as the thenar eminentia to grip the handle (16), so that the upper body exercise assistance device (1) may be more stably supported on the user's palm. The connecting frame (15) may include a lower frame (151), an upper frame (152), and a handle support frame (153).

[0034] In one embodiment, the lower frame (151) may be formed to extend from the housing (11). The relative movement of the lower frame (151) with respect to the housing (11) may be limited. For example, the lower frame (151) and the housing (11) may be connected to each other through an interlocking structure. The lower frame (151) may be formed of the same material as the housing (11) and may form a part of the housing (11).

[0035] The lower frame (151) can be formed to extend in a first direction, a second direction, and a third direction. Here, the first direction is the longitudinal direction of the lower body, and the second direction is the direction in which the housing (11) faces the lower body. The third direction is a direction perpendicular to each of the first and second directions. With reference to FIG. 3, the first direction is parallel to the z-axis, the second direction is parallel to the x-axis, and the third direction is parallel to the y-axis. The first direction includes the +z direction and the -z direction, the second direction includes the +x direction and the -x direction, and the third direction includes the +y direction and the -y direction.

[0036] In one embodiment, the lower frame (151) may extend from the housing (11) in the -y direction and the +z direction, so as to point from the inside of the user's wrist toward the user's hand (see FIG. 2). At the same time, the lower frame (151) may also extend in the -x direction, so as to point from the inside of the user's wrist toward the user's palm (see FIG. 3).

[0037] In one embodiment, the upper frame (152) may be formed to extend in the +z direction from the lower frame (151). The handle support frame (153) to which the handle (16) is connected may be formed to extend in the +y direction from the upper frame (152). Meanwhile, the upper frame (152) may extend in the +z direction as well as the -y direction. At this time, the handle (16) may not be parallel to the longitudinal direction of the strap (14) but may be inclined, as described above. When the user holds the inclined handle (16), the wrist may be in a slightly extended state. The wearing comfort of the upper body exercise assistance device (1) may be further improved.

[0038] In one embodiment, the handle (16) may be connected to a handle support frame (153). The handle (16) may include a handle body (161) and a handle cover (162). The handle body (161) may have a handle hole for accommodating the handle support frame (153). The handle hole may be formed along the longitudinal direction of the handle body (161). The handle body (161) may have a cylindrical shape with an interior that is hollow. The handle body (161) may be formed of a lightweight and strong material, such as carbon steel.

[0039] In one embodiment, the handle cover (162) surrounds the handle body (161) and may include a material more flexible than the handle body (161). For example, the handle cover (162) may be formed of polyurethane foam. The handle cover (162) may have a cylindrical shape with an interior that is hollow. The handle body (161) may be accommodated in a hole formed within the handle cover (162) along the longitudinal direction of the handle cover (162).

[0040] In one embodiment, after the handle cover (162) is placed on the handle body (161), the handle cap (163) may be connected to the side of the handle body (161). The handle cap (163) may be formed of, for example, a plastic material. The two ends of the handle cover (162) surrounding the handle body (161) may be supported by the upper frame (152) and the handle cap (163), respectively. Even if the user exercises for a long time, the handle cover (162) may not be separated from the handle body (161).

[0041] In one embodiment, the interior of the handle body (161) is sealed by the handle support frame (153) and the handle cap (163), so that foreign substances may not enter the interior of the handle body (161). When a sensor is placed inside the handle body (161), damage to the sensor may be reduced.

[0042] In one embodiment, the handle body (161) may be provided to be detachably attached to the handle support frame (153). The handle (16) connected to the connecting frame (15) may be replaced. For example, depending on the type of exercise, a handle (16) made of a material suitable for the exercise may be used. If the handle (16) is damaged or worn due to long-term use of the upper body exercise assistance device (1), the handle (16) may be separated from the connecting frame (15) and only the handle (16) may be replaced. Maintenance costs for the upper body exercise assistance device (1) may be reduced.

[0043] FIG. 5 is a front view illustrating a handle body, a handle cover, and a switch according to one embodiment.

[0044] Referring to FIG. 5, a handle (26) according to one embodiment may further include a switch (264). The switch (264) may be placed on the handle body (261). The switch (264) may detect pressure from a user's finger and transmit the detected signal to a communication unit. For example, the switch (264) may be a button that, when pressed by a user, causes a portion of the switch to retract into the handle body (261) and then returns to its original position. A hole (265) for accommodating the switch may be formed in the handle cover (262).

[0045] In one embodiment, when the upper body exercise assistance device is utilized in an exercise game, the user may use a handle body (261) having different switches (264) depending on the type of game. The position of the switches (264) on the handle (26), the shape of the switches, the number of switches, etc. may vary. For example, the switches (264) may be provided on the handle cap (263) and may sense pressure from the user's thumb.

[0046] Fig. 6 is a front view illustrating the inside of a tension sensor according to one embodiment.

[0047] Referring to FIG. 6, a tension sensor (18) according to one embodiment can measure tension applied to a cable (C) when a user performs resistance exercise. The measurement value measured by the tension sensor (18) can be transmitted to a communication unit.

[0048] In one embodiment, the tension sensor (18) may be an optical sensor. The tension sensor (18) may include a fixed frame (181), a driving frame (182), and a light detection element (183). The fixed frame (181) may be fixed to a housing that surrounds the fixed frame (181) and the driving frame (182). The light detection element (183) may be disposed on the lower side of the fixed frame (181) and may face the driving frame (182). The light detection element (183) may be connected to a communication unit via a wire (W) and may be controlled by the communication unit. The light detection element (183) may emit light toward the driving frame (182) and detect the reflected light returning.

[0049] In one embodiment, when tension is applied to the cable (C), the drive frame (182) connected to the cable (C) may deform or move downward relative to the fixed frame (181). The intensity of light reflected by the drive frame (182) may decrease, and the time it takes for the reflected light to reach the light detection element (183) may increase. The light detection element (183) may calculate the magnitude of the tension corresponding to values ​​such as the intensity of the detected light, the arrival time of the reflected light, etc. The calculated magnitude of the tension may be transmitted to the communication unit through the wire (W).

[0050] In one embodiment, the tension sensor (18) may be positioned on the opposite side of the handle relative to the housing. Since the user's hand and forearm move in unison while wearing the upper body exercise assistance device, accurate tension can be measured even if the tension sensor (18) is directly connected to the communication unit rather than the handle. By directly connecting the wire (W) to the communication unit without going through the handle, the length of the wire (W) can be reduced, and the design of the upper body exercise assistance device can be simplified. Within the range in which the tension sensor (18) is connected to the housing by the wire (W), the tension sensor (18) can move freely with respect to the housing, and can measure tension applied in various directions.

[0051] Although the drawing of this specification shows that the cable (C) is directly connected to the tension sensor (18), it should be noted that, alternatively, a carabiner may be connected to the tension sensor (18).

[0052] FIG. 7 is a block diagram schematically illustrating a process of controlling a housing motor and a strap motor of an upper body exercise assistance device according to one embodiment.

[0053] Referring to FIG. 7, the communication unit (12) of the upper body exercise assistance device according to one embodiment is connected to a device and a personal computer (PC) to assist the user's arm movement through feedback control. Here, the device may be a device that is directly connected to the upper body exercise assistance device and cooperates with the upper body exercise assistance device to provide exercise to the user, such as a wearable robot. The PC may include not only a desktop computer, but also a tablet, a smartphone, a smartwatch, and the like.

[0054] In one embodiment, the communication unit (12) of the upper body exercise assistance device may be wirelessly connected to the device using, for example, Bluetooth low energy (BLE). The communication unit (12) may transmit the measured values ​​from the IMU sensor (17) and the tension sensor (18) to the device. The device may transmit the received measured values ​​to a PC. The PC may display, analyze, and store the measured values ​​received from the device.

[0055] In one embodiment, the PC may control the device based on the analyzed data to provide feedback to the user regarding the intensity of the exercise. For example, the PC may determine that the tension measured by the tension sensor (18) is less than the user's target tension. The PC may manually or automatically control a motor located within the wearable robot that winds and unwinds the cable to increase resistance to the exercise. The amount of force required to pull the cable back to its previous position may increase, thereby increasing the intensity of the exercise.

[0056] In one embodiment, the PC can control the device based on the analyzed data to provide feedback to the user regarding the direction of movement. For example, the PC can determine that the position of the user's arm, measured by the IMU sensor (17), is lower than the position set by the user. The PC can manually or automatically control the motors arranged in the wearable robot to have a speed appropriate for the guided direction of movement. The wearable robot can guide the direction of movement to the communication unit (12) of the upper body movement assistance device. The communication unit (12) can receive a signal from the wearable robot and vibrate the housing motor (13) arranged on the user's wrist and the multiple strap motors (19), thereby guiding the direction of movement to the user. Meanwhile, the communication unit (12) of the upper body movement assistance device can also be controlled directly from the PC without going through the device. In this case, the PC, like the device, can be understood to be wirelessly connected to the upper body movement assistance device.

[0057] In one embodiment, the strap motor (19) is disposed within the strap and can generate vibrations by receiving signals from the communication unit (12). The strap motor (19) may be, for example, the same type of motor as the housing motor (13). The user can perceive the vibrations generated by the strap motor (19) through the skin. The housing motor (13) may be disposed on the inside of the user's wrist, and the strap motor (19) may be disposed along the user's wrist. The strap motor (19) may be disposed in multiple numbers. For example, as illustrated in FIG. 8, there are three strap motors (19), and they may be disposed spaced apart from each other along the circumference of the wrist based on the housing motor (13) disposed on the inside of the user's wrist.

[0058] In one embodiment, the housing motor (13) and the strap motor (19) may receive a signal from the communication unit (12) and generate a vibration pattern by vibrating only one of them, both of them simultaneously, or both of them sequentially. For example, when the user's arm is guided to move in a certain direction by the communication unit (12), any one of the housing motor (13) and the strap motor (19) located in the corresponding direction may vibrate. For example, when the user's arm is guided to move in a clockwise direction, the housing motor (13) and the plurality of strap motors (19) may vibrate sequentially in the clockwise direction. For example, when it is notified that the number of the user's exercise movements has been counted, the housing motor (13) and the plurality of strap motors (19) may vibrate twice simultaneously.

[0059] FIG. 8 is a plan view illustrating a user wearing an upper body exercise assistance device according to one embodiment, and FIG. 9 is a cross-sectional view schematically illustrating an inner layer, a support body, an outer layer, and a housing according to one embodiment.

[0060] Referring to FIGS. 8 and 9, a strap according to one embodiment may include an inner layer (141), a support body (142), and an outer layer (144). The inner layer (141) may contact the user's wrist (H). To facilitate understanding, it is noted in advance that a gap is depicted between the inner layer (141) and the user's wrist (H) in FIG. 8.

[0061] In one embodiment, the inner layer (141) may be formed of a thin material to provide a cushioning feeling to the user's wrist (H) and to effectively transmit the vibrations of the housing motor and strap motor (19) to the skin. The inner layer (141) may be formed of, for example, a mesh material.

[0062] In one embodiment, the support body (142) may be disposed on the inner layer (141) and may support the strap motor (19). The support body (142) may be formed of a shock-absorbing material, such as polyurethane foam, to reduce the impact applied to the strap motor (19). The outer layer (144) may cover the support body (142). For example, the outer layer (144) may be formed of a leather material.

[0063] In one embodiment, the support body (142) may include a motor groove (143) that is formed recessed in a surface facing the inner layer (141) and supports the strap motor (19). The support body (142) is provided in surface contact with the inner layer (141), and at least a portion of the strap motor (19) may contact the inner layer (141). From this structure, the bonding strength between the support body and the inner layer (141) and the vibration level of the strap motor (19) transmitted to the user may increase.

[0064] In one embodiment, a plurality of strap motors (19) may be provided along the longitudinal direction of the strap. A plurality of support bodies (142) may also be provided along the longitudinal direction of the strap to support each of the plurality of strap motors (19). At this time, the plurality of support bodies (142) may be provided in a state of being spaced apart from each other. Vibration generated from one strap motor (19) may not be transmitted to another adjacent support body (142) through the support body (142) surrounding the strap motor (19). Vibration generated from one strap motor (19) may be locally transmitted to the user.

[0065] In the drawings of this specification, the strap is shown to be fixed to the housing (11) by being assembled with screws, but alternatively, the strap may be fixed to each of the two sides of the housing (11).

[0066] An upper body exercise assistance device according to one embodiment may include a housing disposed on a user's lower arm, a communication unit disposed on the housing, a housing motor disposed on the housing and receiving a signal from the communication unit to generate vibration, a strap connected to the housing and wearable on the user's lower arm, a connecting frame extending from the housing, a handle connected to the connecting frame and capable of being gripped by the user, and an IMU sensor disposed on the handle or the housing and transmitting a measurement value to the communication unit.

[0067] According to one embodiment, when the longitudinal direction of the lower body is a first direction and the direction in which the housing faces the lower body is a second direction, the connecting frame may include a lower frame that extends in the first direction and the second direction.

[0068] According to one embodiment, the lower frame may be formed to extend in a third direction perpendicular to each of the first direction and the second direction.

[0069] According to one embodiment, the connecting frame may further include an upper frame extending in the first direction from the lower frame.

[0074] An upper body exercise assistance device according to one embodiment may further include at least one strap motor disposed within the strap and configured to receive a signal from the communication unit and generate vibration.

[0075] According to one embodiment, the strap may include an inner layer that is contactable with the user's wrist, at least one support body that is disposed on the inner layer and supports the strap motor, and an outer layer that covers the at least one support body.

[0076] According to one embodiment, the support body may include a motor groove formed recessed in a surface facing the inner layer and supporting the strap motor.

[0077] According to one embodiment, the support body is provided in surface contact with the inner layer, and at least a portion of the strap motor can contact the inner layer.

[0078] According to one embodiment, the strap motors may be provided in multiple numbers along the length direction of the strap.

[0079] According to one embodiment, the support body is provided in a plurality along the length direction of the strap, and each of the plurality of support bodies can support one strap motor among the plurality of strap motors.

[0080] According to one embodiment, the plurality of support bodies may be provided spaced apart from each other.

[0081] According to one embodiment, the housing motor and the plurality of strap motors can receive a signal from the communication unit and vibrate simultaneously or sequentially to generate a vibration pattern.

[0082] An upper body exercise assistance device according to one embodiment may further include a tension sensor to which a cable may be detachably connected and which transmits a measurement value to the communication unit.

[0083] In one embodiment, the tension sensor may be positioned opposite the handle relative to the housing.
