[0034] Referring to FIGS. 1 to 9, a dumbbell (100) having an auxiliary battery according to the present invention comprises an auxiliary handle (110), a weight (120), a sensor module (130) installed on the handle (110), a control module (140) installed on the handle (110), a display module (150) installed on the handle (110), a speaker module (160) installed on the weight (120), a coupling module (170) for detachably coupling the handle (110) and the weight (120), and an LED lamp (180) installed on the weight (120).

[0035] A dumbbell (100) is an exercise device that allows a user to perform strength exercises while holding a handle (110). The dumbbell (100) has a bar shape and is equipped with a handle (110) that the user holds and weights (120) provided at each end of the handle (110).

[0036] In this embodiment, a coupling module (170) is provided to allow weights (120) to be detachably attached to both ends of the handle (110). Accordingly, the dumbbell (100) according to this embodiment can be configured to allow weight adjustment by replacing the weights (120). The weights (120) may be coated with a polymer rubber material that can minimize impact when falling during exercise.

[0037] Meanwhile, in this embodiment, to utilize the dumbbell (100) as an interior decoration item, that is, to obtain an interior lighting effect, an LED lamp (180) is installed on the weight (120) with reference to FIGS. 5 and 6. The LED lamp (180) is electrically connected to an auxiliary battery (111) built into the handle (110) and receives power from the auxiliary battery (11). The LED lamp (180) can be turned on / off via an on / off switch (not shown) separately installed on the handle (110), and the brightness of the LED lamp (180) can be adjusted via a brightness control switch (not shown) separately installed on the handle (110).

[0038] LED lamps (180) can be attached to each end of the handle (110) and installed on the inner surface of mutually facing weights (120). Additionally, LED lamps (180) can be arranged in a band shape along the circumference of the handle (110) on the inner surface of each mutually facing weight (120) (see FIG. 5).

[0039] And as described above, the present embodiment has an auxiliary battery (111) embedded in the handle (110) to supply power to the LED lamp (180) and simultaneously supply power to the sensor module (130), the control module (140), the display module (150), and the speaker module (160). Additionally, a charging terminal (112) is installed in the handle (110) to charge the auxiliary battery (111). The charging terminal (112) includes a Type-C terminal (112a) and a USB terminal (112b) installed in the handle (110).

[0040] The present embodiment also includes a coupling module (170) that allows the handle (110) and the weight (120) to be mutually detachably coupled, and simultaneously enables electrical connection of the auxiliary battery (111) built into the handle (110), the LED lamp (180) and speaker module (160) installed on the weight (120), etc.

[0041] The coupling module (170) is positioned between the end of the handle (110) and the weight (120) to enable the handle (110) and the weight (120) to be mutually detachable. The coupling module (170) also electrically connects the auxiliary battery (111) and the LED lamp (180). One side of the coupling module (170) is connected to the end of the handle (110) and the other side can be connected to the weight (120) by magnetic force so that the handle (110) and the weight (120) can be detachably connected.

[0042] Referring to FIG. 3, the coupling module (170) includes a main body (171) having a first coupling groove (172) formed on one side into which the end of a handle (110) is inserted, and a protrusion (173) formed on the other side into which a second coupling groove (121) formed in the center of a weight (120) is inserted to electrically connect an auxiliary battery (111) and an LED lamp (180); a magnetic body (175) provided on the other side of the main body (171) and arranged along the edge of the protrusion (173) to be coupled to the weight (120) by magnetic force; and a shielding member (177) provided on the other side of the main body (111) and arranged between the protrusion (173) and the magnetic body (115) to shield the magnetic field.

[0043] With the end of the handle (110) inserted into the first coupling groove (172), the protrusion (173) formed at the center of the other side of the main body (111) is inserted into the second coupling groove (121) of the weight (120). When the end of the handle (110) is inserted into the first coupling groove (172), the protrusion (173) and the auxiliary battery (171) built into the handle (110) are electrically connected, and when the protrusion (173) is inserted into the second coupling groove (121), the protrusion (173) and the LED lamp (180) and speaker module (160) are electrically connected.

[0044] And, so that the handle (110) and the main body (171) can be firmly attached to the weight (120), a magnetic body (175) is placed along the edge of the protrusion (173) on the other side of the main body (171). The magnetic body (175) may be formed in a band shape that is placed along the edge of the protrusion (173). The main body (171) and the weight (120) are attached to and detached from each other by the magnetic force of the magnetic body (175), thereby allowing the weight (110) and the handle (110) to be attached and detached.

[0045] In addition, since electromagnetic induction may occur and eddy currents may be generated when coupled by a magnetic body (175), a shielding member (177) that shields the magnetic field is provided between the part through which current flows and the magnetic body (175). That is, the shielding member (177) is placed between the protrusion (173) and the magnetic body (175) to shield the magnetic field. In this embodiment, the shielding member (177) may be made of an epoxy resin-coated ferrite material.

[0046] The sensor module (130) according to the present embodiment is installed inside the handle (110) and detects position information and rotation angle of the dumbbell (100) during the user's exercise.

[0047] The sensor module (130) may be composed of a 3-axis accelerometer gyro sensor installed inside the handle (110) (see FIG. 7). The 3-axis accelerometer gyro sensor (130) is installed on both sides of the handle (110) at a distance from each other and can detect the position information and rotation angle of the dumbbell (100) in real time.

[0048] The position information and rotation angle of the dumbbell (100) detected by the 3-axis accelerometer gyro sensor (130) may be provided to the display module (150) and / or speaker module (160) to be described later.

[0049] The control module (140) according to the present embodiment is installed inside the handle (110) and determines the user's exercise posture based on the position information and rotation angle of the dumbbell (100) detected by the sensor module (130), generates correction data to correct the user's exercise posture when the user's exercise posture deviates from the normal range, and guides the user to the correct posture.

[0050] The control module (140) includes a posture determination unit (141) that determines whether the user's exercise posture is within a normal range, a data generation unit (142) that generates correction data, a guidance unit (143) that guides the correction posture, and an alarm unit (144) that notifies of a dangerous situation (see FIG. 8).

[0051] The posture determination unit (141) determines whether the user's exercise posture is within a normal range by comparing the position information and rotation angle of the dumbbell (100) detected by the sensor module (130) composed of a 3-axis accelerometer gyro sensor with a set value. In this embodiment, the appropriate movement trajectory of the dumbbell (100) and the appropriate rotation angle at the corresponding position during exercise can be calculated using the position information and rotation angle of the dumbbell (100) collected in advance through the 3-axis accelerometer gyro sensor (130). The set value is a value that is a predetermined angle greater than the appropriate movement trajectory of the dumbbell (100) and the appropriate rotation angle at the corresponding position.

[0052] For example, if the position information and rotation angle of the dumbbell (100) detected in real time by the sensor module (130) exceed a set value that is 3° greater than the appropriate rotation angle at the corresponding position on the appropriate movement trajectory, it can be determined that the user's exercise posture is abnormal. In this embodiment, the set value is not limited to 3°, and can be set in various ways considering the user's muscle or joint injury, physical imbalance, etc. during exercise.

[0053] Whether the user's exercise posture is normal or abnormal, as determined by the posture determination unit (141), can be provided to the display module (150) and / or speaker module (160) to be described later.

[0054] The data generation unit (142) generates correction data to correct the user's exercise posture when the user's exercise posture determined by the posture determination unit (141) is abnormal and outside the normal range. The correction data may be a value corresponding to the angle exceeding the set value when the rotation angle at the corresponding position of the dumbbell (100) detected by the sensor module (130) exceeds the appropriate rotation angle at the corresponding position on the appropriate movement trajectory. Correction data based on the rotation angle of the dumbbell (100) detected in real time may also be stored in real time.

[0055] As described above, when correction data is generated and stored by the data generation unit (142), the guidance unit (143) can guide the user to a correction posture based on the correction data. The correction posture is to correct the direction of rotation of the dumbbell (100) in the opposite direction to the actual direction in which the dumbbell (100) is rotated by an angle of rotation of the dumbbell (100) that exceeds the set value, that is, an angle corresponding to the correction data.

[0056] A corrective posture based on correction data, which is the rotation angle of the dumbbell (100) that exceeds the set value at the corresponding position of the dumbbell (100), can be guided to the user through the display module (150) and / or speaker module (160). At this time, whether the dumbbell (100) is rotated in which direction can also be guided. The user can perform the exercise in the correct exercise posture according to the guidance unit (143).

[0057] Meanwhile, if the user's exercise posture is abnormal and exceeds a set value, or if the abnormal state persists, the risk of an accident during exercise may increase. Accordingly, the alarm unit (144) can generate an alarm signal indicating a dangerous situation when the user's exercise posture is abnormal and the duration of the abnormal exercise exceeds a predetermined time. The alarm signal is made so that the user can immediately recognize it visually and / or audibly through the display module (150) and / or speaker module (160).

[0058] Also, as the user's physical strength is depleted as the exercise is repeated, the probability of an abnormal posture being detected may increase. Additionally, depending on the weight of the dumbbell (100), the number of repetitions per set, and the number of repetitions per set, the probability of an abnormal posture being detected may increase when the exercise is continued.

[0059] Considering these points, the predetermined time may vary depending on the duration of the exercise, the weight of the dumbbell (100), the number of repetitions per set, and the number of repetitions per set, so the user can input the predetermined time by considering the above points.

[0060] For example, while performing one set, a predetermined time can be set to 5 seconds and if the abnormal condition exceeds 5 seconds, an alarm signal indicating a dangerous situation can be generated, and while performing three sets, a predetermined time can be set to 10 seconds and if the abnormal condition exceeds 10 seconds, an alarm signal indicating a dangerous situation can be generated.

[0061] Meanwhile, as described above, position information and rotation angle of the dumbbell (100) detected by the sensor module (130), whether the user's exercise posture is normal or abnormal determined by the posture determination unit (141), the corrective posture guided by the guidance unit (143), and the alarm signal regarding a dangerous situation generated by the alarm unit (144) may be provided to the display module (150) and / or speaker module (160) (see FIG. 9). FIG. 9 is an example showing the rotation angle of the dumbbell (100) at the corresponding position displayed on the display module (150).

[0062] The display module (150) may be composed of an LED display installed on the outer surface of the center of the handle (110). The control module (140) may further include a communication unit (145) to enable wired and wireless communication with the display module (150) and / or the speaker module (160). The communication unit (145) may utilize a communication network such as wired, Wi-Fi, Zigbee, or Bluetooth. Additionally, the communication unit (145) is capable of wired and wireless communication with the LED lamp (180), and the on / off operation and brightness adjustment of the LED lamp are possible through the control module (140).

[0063] The display module (150) visually provides the position information and rotation angle of the dumbbell (100) detected by the sensor module (130), whether the user's exercise posture is normal or abnormal as determined by the posture determination unit (141), the corrective posture guided by the guidance unit (143), and the alarm signal regarding the dangerous situation generated by the alarm unit (144) so ​​that the user can recognize them.

[0064] And the speaker module (160) provides audibly so that the user can recognize the position information and rotation angle of the dumbbell (10) detected by the sensor module (130), whether the user's exercise posture is normal or abnormal determined by the posture judgment unit (141), the corrective posture guided by the guidance unit (143), and the alarm signal regarding the dangerous situation generated by the alarm unit (144).

[0065] Meanwhile, in this embodiment, the display module (150) is shown installed on the handle (110) and the speaker module (160) is shown installed on the weight (120), but the display module (150) and the speaker module (160) may be a display and a speaker provided in a user terminal capable of communicating with the control module (140). The user terminal may be configured as a wireless communication terminal, for example, a tablet computer, a laptop, a mobile phone, a personal digital assistant (PDA), a smartphone, etc.

[0067] The method for correcting exercise posture using a dumbbell equipped with an auxiliary battery according to the present invention configured as described above is as follows.

[0068] FIG. 10 is a flowchart illustrating an exercise posture correction method according to the present invention.

[0069] First, the position information and rotation angle of the dumbbell (100) collected through the 3-axis accelerometer gyro sensor (130) can be used to calculate the appropriate movement trajectory of the dumbbell (100) during exercise and the appropriate rotation angle at the corresponding position.

[0070] And, referring to FIG. 10, when a user starts exercising using a dumbbell (100), a sensor module (130) installed on a handle (110) detects the position information and rotation angle of the dumbbell (100) in real time during the user's exercise (S100).

[0071] In this embodiment, the sensor module (130) is composed of a 3-axis accelerometer gyro sensor, and the 3-axis accelerometer gyro sensor can precisely detect the position information and rotation angle of the dumbbell (100). The rotation angle of the dumbbell (100) indicates the angle at which the dumbbell (100) is tilted in one direction or both directions in the front, back, left, and right directions.

[0072] Then, during the user's exercise, the user's exercise posture is provided based on the position information and rotation angle of the dumbbell (100) detected in real time (S200). The user's exercise posture is provided to the user visually and / or audibly through the display module (150) and / or speaker module (160) regarding the position information of the dumbbell (100) and the rotation angle of the dumbbell (100) at that position.

[0073] Then, during the user's exercise, the position information and rotation angle of the dumbbell (100) detected in real time are compared with the set value to determine whether the user's exercise posture falls within the normal range (S300).

[0074] The set value is a value that is greater than the appropriate rotation angle at the appropriate movement trajectory and corresponding position of the dumbbell (100), and the position information and rotation angle of the dumbbell (100) detected by the sensor module (130) are compared with the set value to determine whether the user's exercise posture falls within the normal range. That is, if the position information and rotation angle of the dumbbell (100) at the corresponding position are within the set value that is greater than the appropriate rotation angle at the corresponding position on the appropriate movement trajectory, the exercise posture is determined to be normal (S310). On the other hand, if the position information and rotation angle of the dumbbell (100) exceed the set value which is the appropriate rotation angle at the corresponding position on the appropriate movement trajectory, the exercise posture is determined to be abnormal (S320).

[0075] In addition, the user may be visually provided with information on whether the user’s exercise posture is normal through the display module (150) and / or speaker module (160). The user may continue or stop exercising after visually or audibly confirming whether the exercise posture is normal.

[0076] And if the user's exercise posture is abnormal and outside the normal range, it is determined whether the duration of the abnormal exercise exceeds a predetermined time (S400).

[0077] If the duration of the user's abnormal exercise posture exceeds a predetermined time, an alarm signal regarding the dangerous situation is generated to the user through the display module (150) and / or speaker module (160) (S450).

[0078] The user can be notified of a dangerous situation through the display module (150) and / or speaker module (160), so that the user can immediately recognize the dangerous situation and stop exercising. Conversely, if the duration of the user's abnormal exercise posture is within a predetermined time, the user's abnormal exercise posture can be corrected.

[0079] If the user's exercise posture is abnormal and the duration of the user's abnormal exercise posture is within a predetermined time, correction data is generated to correct the user's exercise posture (S500).

[0080] The calibration data may be a value corresponding to the angle exceeding the set value when the rotation angle at the corresponding position of the dumbbell (100) detected by the sensor module (130) exceeds the appropriate rotation angle at the corresponding position on the appropriate movement trajectory. The calibration data according to the rotation angle at each position of the dumbbell (100) detected in real time may also be stored in real time.

[0081] And based on the correction data mentioned above, the user is guided to a correction posture (S600).

[0082] The corrective posture is to correct the direction of rotation of the dumbbell (100) in the opposite direction to the actual direction in which the dumbbell (100) is rotated by an angle corresponding to the correction data, that is, the angle of rotation of the dumbbell (100) that exceeds the set value. The corrective posture may be guided to the user through the display module (150) and / or speaker module (160). The user can perform the exercise in the correct exercise posture according to the guided corrective posture.

[0084] As such, it is obvious to those skilled in the art that the present invention is not limited to the described embodiments and can be modified and varied in various ways without departing from the spirit and scope of the invention. Accordingly, such modified or varied embodiments should be deemed to fall within the scope of the claims of the present invention. Explanation of the symbols
