Description

Haptic gripper and operation method of haptic gripper {A HAPTIC GRIPPER AND AN OPERATION METHOD OF THE SAME}

The present invention relates to a haptic gripper and a method of operating the haptic gripper.

Hereinafter, the gripper collectively refers to a device in which vibration is fed back when it is held in a hand and pressed. You can use the gripper to exercise your hand.

The present invention provides a haptic gripper capable of feeding back a haptic response according to a movement of a hand when exercising with a hand, and an operation method thereof.

The haptic gripper of the present invention comprises: a case portion gripped by a hand; A control unit generating a haptic vibration corresponding to a pressing time pressed by a hand; It may include.

The case portion is formed of a soft portion and a hard portion, a button portion is provided in the soft portion, and a pressing time of the button portion may be a pressing time when the button is pressed by the hand.

Meanwhile, the case portion may include an inner case and an outer case, and the inner case may be inserted into the outer case.

The method of operating a haptic gripper according to the present invention includes: preparing a haptic gripper provided in a case part with a control part, a button part, and a motor part; Comparing the first pressing time with a first set value when the button unit is pressed by a first pressing time by holding the haptic gripper by hand; Initiating a standby mode when the first pressing time is greater than a first set value; Determining an operation pattern or operation time of the motor unit in response to a first pressing time of the button unit, and executing a haptic mode for operating the motor unit; After the haptic mode is started, turning off the power of the control unit or the motor unit according to a time when the button unit is pressed; It may include.

When exercising with hands, a gripper that exhibits a haptic response according to the movement of the hand has not been developed.

The present invention relates to a brain activation mechanism through hand movement and stimulation. When a rubber-based soft material with appropriate elasticity forms an outer case and holds it in the hand and applies force, it can cause deformation at an appropriate level.

On the other hand, even when the case is not separated into several parts including an inner case and an outer case, a part of the case may be hard and the other part may be soft. A battery or a terminal portion may be formed in the hard part of the case. The soft part can be held in the hand and can act as an input means for receiving hand movements. The hard part or the soft part may serve as an output means for transmitting the haptic vibration of the motor to the hand.

In addition, the motor generates vibration, so you can perform hand pressure and exercise with a small force. Therefore, even the elderly can exercise easily.

The vibration of the gripper can be converted into music, and the rhythm of music can be learned through vibration. At least one of a music play function and a rhythmic vibration function may be performed to maintain the fun and continuity of the exercise.

1 is a cross-sectional view of the haptic gripper of the present invention.

Referring to FIG. 1, the haptic gripper of the present invention may include a case unit and a control unit 300.

The case portion may be held in the hand. It is used for hand acupressure and massage, so it can be a size that fits your hand.

The controller 300 may be set to one of an on mode, a haptic mode, and an off mode according to a pressing time when the case unit or the button unit 110 is pressed.

The on mode is a mode in which haptic vibration is turned on by turning on the control unit 300 or the motor unit 200.

The haptic mode is a mode in which haptic vibration is generated by the motor unit 200 after the on mode.

The off mode is a mode in which the control unit 300 or the motor unit 200 is turned off after the haptic mode to stop haptic vibration.

Each person may have different intensity and time to press the case. In the present invention, rather than recognizing the strength of pressing the case portion, various modes may be executed according to the time the case portion is pressed.

When the first time the case is pressed for the first time is greater than or equal to the first set value (eg, 7 seconds), the on mode may be entered. When entering the on mode, the haptic mode is initiated, and haptic vibration may occur. The length of the haptic mode may be determined in proportion to the length of the first time, which is a time when the case portion is pressed to enter the on mode.

For example, when the difference between the first time and the first set value is the first length, the haptic mode may last for a time proportional to the first length. On the other hand, when the difference between the first time and the first set value is the second length, the haptic mode may last for a time proportional to the second length.

When the case portion is pressed after the haptic mode, the off mode may be entered. The off mode is a mode in which the control unit 300 or the motor unit 200 is turned off to stop haptic vibration.

As described above, at least one of a haptic vibration mode, a time point at which the haptic vibration starts, and a time during which the haptic vibration continues may be varied according to the user's strength or preference.

The haptic vibration mode can be set in various ways. For example, the on mode may be a mode in which the controller 300 or the motor unit 200 is turned on in a ready state, and the off mode may be a mode in which the controller 300 or the motor unit 200 is turned off in a rest state.

Meanwhile, the controller 300 may identify a user in response to a pressing time when the case unit or the button unit 110 is pressed. It may be good if the controller 300 uses an AI neural engine that automatically determines and learns who is using it and how much force is pressed.

If the first user pressed the first pattern at the first time point, the controller 300 may memorize it. When the first user uses the haptic vibrator at a second viewpoint different from the first viewpoint, the controller 300 may recognize the user as the first user with respect to the user who pressed the haptic vibrator in the same pattern as the first pattern. If the user presses in a pattern different from the first pattern, the controller 300 may recognize the user as a second user.

Meanwhile, the controller 300 may generate a haptic vibration according to a pattern of haptic vibration or a music rhythm in response to a pressing time when the case unit or the button unit 110 is pressed. The pattern of haptic vibration can be selected according to the pressing time, and this pattern can be tailored to the music rhythm.

The case portion may include an inner case 100 and an outer case 500.

The inner case 100 may be a hard case including major parts. When the inner case 100 is used as a hard hard case, the main parts do not move and can be stably fixed without damage.

As a comparative example, when the inner case 100 is a soft case that is not hard, the overall weight may be reduced. Here, because the material is soft due to the assumed characteristics of the soft case, major parts may bump into each other and cause damage. The inner case 100 of the present invention is preferably a hard case.

The inner case 100 may be made of a harder material than the outer case 500. Since the main parts enter the inner case 100, it can be stably fixed to prevent movement. If the inner case 100 is also made of a plastic or rubber-based soft material having an appropriate elasticity, the weight may be too light and there may be no feeling of grip and weight when gripped. There may be cases where internal parts collide, which can cause a major problem in durability. Since the inner case 100 is inserted into the outer case 500, the size may be smaller than that of the outer case 500.

Meanwhile, the outer case 500 may be a soft case because it is a part that is held by hand. It is soft and can feel good when held in hand. It can be easily used as a toy for the elderly, women, and children with relatively weak strength.

As a comparative example, when the outer case 500 is used as a hard hard case, the acupressure effect may be better. However, the use of a hard hard case can be a lot of power for the elderly, women, and children who have relatively weak strength. Due to the characteristics of the haptic gripper, the softer the outer case 500 may be, the better.

The outer case 500 may be made of a plastic or rubber-based soft material having appropriate elasticity. Due to the soft nature of elastic plastic or rubber-based soft materials, even the elderly can exercise easily without much effort. It can also help prevent dementia or delay dementia. It can also help prevent various diseases. Even for critically ill patients who cannot move their body freely, the effect can be excellent in massage or massage. If you are elderly and lack energy, you can easily and conveniently receive the effects of massage and acupressure at the same time when you sleep with your own hands or palms. It can relax the muscles in the area where acupressure is applied and improve blood circulation. By actively promoting metabolism, it can also relieve hand fatigue.

The following describes the assembly structure.

The inner case 100 may be inserted into the outer case 500. The inner case 100 may be a hard case and the outer case 500 may be a soft case. The inner case 100, which is a hard and hard case including major parts, may be inserted into the outer case 500, which is a soft and soft case that is held by hand.

An opening 510 may be provided in the outer case 500. The inner case 100 may be larger than the size of an empty space inside the outer case 500. Since the inner case 100 is hard, the elasticity is small, and the outer case 500 is soft, so the elasticity may be high. When the outer case 500 is inserted into the empty space of the inner case 100, due to the elasticity of the outer case 500, the inner case 100 elastically adheres to the empty space inside the outer case 500. I can.

In order to improve the haptic feel and obtain an acupressure effect, an external protrusion 550 may be provided. The outer protrusion 550 in the outer case 500 may also be made of a plastic or rubber-based soft material having appropriate elasticity such as the outer case 500. There is an acupressure unit made of an external protrusion 550 formed on the surface of the outer case 500, so that the effect of simultaneously pressing the palm of the hand can be seen while performing muscle strength exercise.

2 is an exploded view of the haptic gripper of the present invention.

Referring to FIG. 2, the outer case 500 may have an insertion space 512, which is a space in which the outer case 500 and the inner case 100 are in close contact with each other so that the inner case 100 cannot move. The inner case 100 may be pushed and assembled into the outer case 500. The inner case 100 may have a structure that fits inside the outer case 500.

An opening 510 in which a part of the outer case 500 is opened may be included as a passage for pushing the inner case 100 into the insertion space 512. The outer case 500 may be torn due to the characteristics of a soft case, and may be worn as the usage increases. It is preferable to be able to easily separate the outer case 500 and the inner case 100. The user can easily purchase and replace the outer case 500 separately. The inner case 100 may use a hard hard case to protect the main parts. In the event of a failure due to careless use, only the inner case 100 can be purchased separately and replaced by the user.

The inner case 100 may include at least one of a motor unit 200 that rotates the eccentric weight 210 or a linear motor and a coin type vibration motor. The battery unit may use a built-in rechargeable battery unit other than a disposable battery unit that can be replaced. It can be easily charged with a mobile phone charger. Even if it is discharged, it can be used immediately with the charging line plugged in. If a disposable battery unit that can be replaced is used, it may be easy for a user to replace the battery unit. If it is discharged, it may not be possible to use it immediately unless you have an extra battery. The weight can be increased because you have to make a slot to attach and remove the battery part. It may not look neat in design.

The inner case 100 may be provided with a USB port unit 420 connecting the battery unit 400 supplying power to the motor unit 200. The USB port unit 420 may sequentially pass through the opening 510, the insertion space 512, and the port hole 520 from the outside of the outer case 500. The USB port unit 420 may protrude from one side of the inner case 100. A port hole 520 through which the USB port unit 420 penetrates may be formed in the outer case 500 to facilitate charging by the user.

The motor unit 200 may be connected to the control unit 300.

At least one of on/off of the motor unit 200, a rotation time, and a type of a haptic mode may be determined according to a control signal from the controller 300. The control unit 300 may turn on/off the motor unit 200 in a signal according to the push of the button unit 110. The control unit 300 may determine the rotation time of the motor unit 200 in a signal according to the pressing time of the button unit 110.

The button unit 110 may be provided between the outer case 500 and the inner case 100.

When the outer case 500 is pressed by hand, the button portion 110 between the outer case 500 and the inner case 100 may be pressed. When the button unit 110 is pressed, haptic vibration of the motor unit 200 may be generated. The control unit 300 may determine whether to operate the motor unit 200 according to whether the button unit 110 is pressed. The operation time of the motor unit 200 may be determined according to the pressing time of the button unit 110.

On the other hand, the case part is not divided into several parts including an inner case and an outer case, but is made of one body, and a part of the case part may be hard and a part of the case may be soft.

A battery or a terminal part may be formed in the hard part of the case part. The soft part of the case part may be held in the hand and may serve as an input means for receiving hand movements. The hard part or the soft part may serve as an output means for transmitting the haptic vibration of the motor to the hand.

3 is a flow chart showing the operation of the haptic gripper of the present invention.

Referring to FIG. 3, the control unit 300, the button unit 110, and the motor unit 200 may be provided with a haptic gripper provided in the case unit. The user can press the button unit 110 in the case unit. The controller 300 may receive a signal according to the pressing of the button unit 110 and the pressing time. The control unit 300 may turn on/off the motor unit 200 in a signal according to the push of the button unit 110. The control unit 300 may determine the rotation time of the motor unit 200 in a signal according to the pressing time of the button unit 110.

When the button unit 110 is pressed by the first pressing time by holding the haptic gripper by hand, the controller 300 may compare the first pressing time with the first set value. When the first pressing time is less than the first set value, the motor unit 200 may not operate. Due to the elasticity of the outer case 500 of plastic or rubber-based softness, hand movement may be possible without turning on the power. Because there are external projections, you can see the acupressure effect. The controller 300 may initiate the standby mode when the first pressing time is greater than the first set value. After the standby mode is started, it may be a step of executing a haptic mode for operating the motor unit 200 for a second pressing time when the button unit 110 is pressed. The intensity and time that the case is pressed against each person may vary.

After the haptic mode is activated, haptic vibrations are continuously generated when the hand is held tightly, so even people such as the elderly can perform hand movements and acupressure without exerting effort. This can help prevent dementia or delay dementia, and can prevent various diseases. It relaxes the muscles of the area where acupressure is applied, improves blood circulation, and actively promotes metabolism to relieve hand fatigue. If the second pressing time after the haptic mode is started is greater than the second set value, it may be a step of turning off the power of the control unit 300 or the motor unit 200. After this step, the power of the motor unit 200 is turned off, but due to the elasticity of the outer case 500, the hand movement may be continuously performed due to the elasticity of the plastic or rubber type. The acupressure effect can also be seen at the same time due to the external projection.
