Description

Helmet size touch adjuster and its control method {HELMET SIZE ADJUSTER AND THE CONTROLLING METHOD THEREOF}

The present invention relates to a helmet size touch adjuster and a control method thereof, and more particularly, to a helmet size touch adjuster for adjusting a helmet size by a touch method and a control method thereof.

In general, in order to adjust the helmet size, a user directly pulls and tightens the strap or uses a dial method to tighten the strap.

Recently, by using the Boa System, a technology already known, tightening the strap to adjust the helmet size, lifting the combined dial outward to release the coupling, the tightened strap is released immediately, making it more convenient to adjust the helmet size.

However, since most of the adjusters for adjusting the size of the helmet are located on the rear side of the helmet, in order for the user wearing the helmet to adjust the size of the helmet, it is inconvenient for the user to place their hands on the back of the user's head to adjust the size of the helmet.

In addition, in this dial method, the user can directly tighten the strap by turning the dial, thereby determining whether or not the size is fixed while feeling the degree of tightness of the strap worn on the head and fixing the strap.

In this case, the user needs to determine and fix the degree of tightening himself, but if the helmet is incorrectly adjusted, it may cause a headache due to the tightening of the helmet, so there is a need to always maintain a constant tightening strength.

Accordingly, the need for a technology for adjusting the helmet size through a simple touch method rather than a dial method and a technology for maintaining a constant tightening strength has increased.

An object of the present invention is to provide a helmet size touch adjuster and a control method for adjusting the helmet size through a touch method.

To achieve this object, a helmet size touch adjuster according to an embodiment of the present invention includes a touch sensor that recognizes a user touch manipulation, a pressure sensor that detects a pressure corresponding to the helmet size adjustment, and a processor that adjusts the helmet size in response to the user touch manipulation, but stops the helmet size adjustment when a pressure equal to or higher than a preset standard is detected through the pressure sensor and fixes the helmet size in the stopped state.

In addition, the processor may perform a different function in response to the number of user touch manipulations recognized during a predetermined time period, or may perform a different function in response to at least one of a touch time and a touch direction of a user touch manipulation.

In addition, the pressure sensor is provided on the inner surface of the housing for adjusting the helmet size, and the processor can stop the function of reducing the helmet size when the function of reducing the helmet size is performed and the pressure sensor provided on the inner surface of the housing is in close contact with the user's head and detects a pressure equal to or higher than the predetermined standard.

In addition, the processor may perform a function of reducing the helmet size when the number of user touch manipulations recognized during the predetermined time period is one time, and may perform a function of increasing the helmet size when the number of times is two times.

In addition, the processor may perform a function of reducing the size of the helmet during a touch time of the user touch manipulation when the touch direction of the user touch manipulation is in a first direction, and may increase the size of the helmet during a touch time of the user touch manipulation when the touch direction is in a second direction.

Meanwhile, the helmet size touch controller according to an embodiment of the present invention may further include an LED lamp emitting light corresponding to the helmet size, and the processor may control the LED lamp to emit light in a first color while performing a function of reducing the helmet size, and control the LED lamp to emit light in a second color while performing a function of increasing the helmet size.

On the other hand, the helmet size touch adjuster according to an embodiment of the present invention includes a storage unit and a memory button unit for storing the fixed helmet size in the stopped state, and the processor can automatically adjust the helmet size to the fixed helmet size in the stopped state when the memory button unit is pressed.

On the other hand, the helmet size touch adjuster according to an embodiment of the present invention further includes a fingerprint recognition unit that recognizes a user's fingerprint, and when a user corresponding to a fingerprint recognized through the fingerprint recognition unit is identified, the processor can automatically adjust the helmet size based on the identified user information.

Meanwhile, a method for controlling a helmet size touch adjuster according to an embodiment of the present invention includes recognizing a user touch manipulation, adjusting a helmet size in response to the user touch manipulation, detecting a pressure corresponding to the helmet size adjustment, and stopping the helmet size adjustment when the sensed pressure is equal to or greater than a preset standard, and fixing the helmet size in the stopped state.

According to various embodiments of the present invention as described above, user convenience can be increased by allowing the helmet to be fixed at a constant tightening strength while easily adjusting the size of the helmet through a touch method.

1 is a block diagram showing the configuration of a helmet size touch controller according to an embodiment of the present invention.

Referring to FIG. 1 , a helmet size touch controller 100 according to an embodiment of the present invention includes a touch sensor 100, a pressure sensor 120, and a processor 130. Here, the helmet size touch controller 100 may be made of synthetic resin, metal, fiber, etc., and may be mainly installed inside the rear surface of the helmet.

The helmet size touch controller 100 may be connected to the inner skin of the helmet, the strap, etc., and the helmet size touch controller 100 adjusts the connected inner skin and strap.

Existing helmet size touch adjusters have dials for adjusting the connected endothelium, straps, etc., and the user directly rotates the dial to adjust the helmet size, whereas the helmet size touch adjuster 100 according to an embodiment of the present invention does not include such a dial, but may include a touch sensor for recognizing touch manipulation.

Specifically, the touch sensor 110 can recognize a user's touch manipulation and can be implemented as a touch panel, an infrared ray transceiver, or the like for recognizing a user's touch manipulation.

For example, in the case of a touch panel, the user's touch manipulation can be recognized by detecting a part of the user's body touching the touch panel, and in the case of an infrared transceiver, the user's touch manipulation can be recognized when the emitted infrared rays are blocked by the user's body part.

The touch sensor 110 may be located on the outer surface of the helmet size touch regulator 100, and thus the user can easily manipulate the touch sensor disposed outside the helmet size touch regulator 100.

Meanwhile, the pressure sensor 120 may detect pressure corresponding to helmet size adjustment.

Specifically, the pressure sensor 120 may detect a pressure value that increases in correspondence to the smaller helmet size as the helmet size decreases, and may detect a pressure value that decreases in correspondence with the increased helmet size as the helmet size increases.

The pressure sensor 120 may be located at a portion where the helmet size touch controller 100 comes in contact with the head, and accordingly, as the helmet size changes, the pressure sensor 120 changes in the portion where the helmet size touch controller 100 touches the head. It can sense the value.

The processor 130 adjusts the size of the helmet in response to the user's touch manipulation, but when a pressure equal to or higher than a predetermined standard is detected through the pressure sensor 120, the helmet size adjustment may be stopped and the helmet size may be fixed at the stopped state.

Specifically, the processor 130 may adjust the size of the helmet in response to a user's touch manipulation recognized through the touch sensor 110 .

For example, the processor 130 may differently adjust the size of the helmet in response to the number of user touch manipulations or the user touch manipulation time. If the number of user touch manipulations is once, the helmet size may be reduced, if the number of user touch manipulations is two times, the helmet size may be increased, or if the user touch manipulation time is 2 seconds or more, the helmet size may be reduced during the touch time period, and if the touch is stopped, the helmet size reduction operation may be stopped.

Further, the processor 130 may stop adjusting the helmet size when the pressure sensed through the pressure sensor 120 is equal to or greater than a preset standard, and may fix the helmet size to the stopped state.

For example, if the pressure value sensed through the pressure sensor 120 is 80 during an operation of reducing the size of the helmet by the processor 130, and exceeds or becomes equal to the predetermined reference value of 80, the processor 130 may stop the operation of reducing the size of the helmet and fix the helmet size while the pressure value in the stopped state remains at 80.

Here, the preset standard or numerical value of the pressure value for stopping the helmet size adjustment can be directly set by the user, and when the preset standard or numerical value setting of the pressure value is completed, the processor 130 controls the pressure sensed through the pressure sensor 120 so that it does not exceed the preset standard or numerical value, and can always adjust the size of the helmet to a certain size and fix it.

2A is a diagram illustrating an external shape of a helmet size touch controller according to an embodiment of the present invention.

Referring to FIG. 2A , the outer shape of the helmet size touch adjuster 100 inserted into the inside of the rear surface of the helmet is shown, and the touch sensor 110 may be provided on the outer surface of the helmet size touch adjuster 100.

Here, although the touch sensor 110 is illustrated as being implemented as a touch panel, it is natural that it is not limited to the touch panel and may be implemented as various parts capable of recognizing touch manipulation.

Meanwhile, the touch panel 110 may be disposed along the outer surface of the helmet-sized touch controller, so as to form a curved surface or a straight surface rather than a curved surface. 2A shows the touch panel 100 arranged to form a curved surface.

Meanwhile, the processor 130 may be included in the helmet size touch controller 100 .

Meanwhile, the processor 130 may perform a different function in response to the number of user touch manipulations recognized for a predetermined time period, or may perform a different function in response to at least one of a touch time and a touch direction of a user touch manipulation.

In addition, the pressure sensor 120 according to an embodiment of the present invention is provided on the inner surface of the housing for adjusting the size of the helmet, and the processor 130 performs a function of reducing the size of the helmet. When the pressure sensor provided on the inner surface of the housing is in close contact with the user's head and detects a pressure equal to or higher than a predetermined standard, the function of reducing the helmet size can be stopped.

2B is a diagram illustrating an internal shape of a helmet size touch controller according to an embodiment of the present invention.

Referring to FIG. 2B, pressure sensors 120, 121, and 122 may be disposed on the inner surface of the helmet size touch regulator 100, and as shown, the first pressure sensor 120 may be disposed to be located opposite the touch panel 110 of the helmet size touch regulator 100, and the second pressure sensor 121 and the third pressure sensor 122 to be located on the guide member or strap itself that directly adjusts the helmet size can be placed.

Accordingly, the first pressure sensor 120, the second pressure sensor 121, and the third pressure sensor 122 disposed can detect pressure values corresponding to the size of the helmet at various positions.

Further, the processor 130 calculates an average value of the pressure values sensed from each of the first pressure sensor 120, the second pressure sensor 121, and the third pressure sensor 122 when there are a plurality of pressure sensors, that is, when the helmet size touch controller 100 includes a total of three pressure sensors, the first pressure sensor 120, the second pressure sensor 121, and the third pressure sensor 122, as shown in FIG. It is possible to determine whether the average value is greater than or equal to a preset standard.

In addition, the processor 130 may stop adjusting the helmet size when the calculated average value is equal to or greater than a preset standard, and may fix the helmet size to the helmet size in the stopped state.

Meanwhile, the processor 130 may perform different functions in response to the number of user touch manipulations recognized for a predetermined time period.

Specifically, the processor 130 may perform a function of reducing the helmet size when the number of user touch manipulations recognized during a predetermined time period is one time, and may perform a function of increasing the helmet size when the number of recognized user touch manipulations during a predetermined time period is two times.

3A is a diagram illustrating a user touch manipulation according to an embodiment of the present invention.

Referring to FIG. 3A , the touch pad 110 provided on the back of the helmet size touch controller 100 is shown, and an operation of a user performing a touch manipulation on the touch pad 110 is shown.

For example, if the user performs a tap operation on the touch pad 110 once, the processor 130 may reduce the size of the helmet in response to the tap operation performed once, and if the user performs a tap operation on the touch pad 110 twice, the processor 130 may increase the size of the helmet in response to the tap operation performed twice.

Here, an operation in which the user touches and releases the touch pad 110 for a certain period of time is defined as a “tap” operation, and the processor 130 may perform different functions according to the number of such “tap” operations.

Also, the processor 130 may perform different functions in response to at least one of a touch time and a touch direction of a user's touch manipulation.

Specifically, the processor 130 may determine that the user touch manipulation is not a “tap” action if the touch time of the user touch manipulation is longer than a predetermined time, and if it is confirmed that the location of the user touch manipulation is changed, it may be determined that the user touch manipulation is not a “tap” action but a “drag” action.

Also, since this drag operation includes touch time and touch direction, the processor 130 may perform different functions according to the touch time and touch direction of the drag operation.

3B is a diagram illustrating a user touch manipulation according to another embodiment of the present invention.

Referring to FIG. 3B , an operation in which a user performs a touch manipulation with respect to the touch pad 110 provided on the rear surface of the helmet size touch adjuster 100 is illustrated.

For example, when the user performs a dragging operation on the touch pad 110 as illustrated, the processor 130 may perform an operation of adjusting the size of the helmet in response to the dragging operation performed.

Here, the dragging operation may include the touch manipulation direction and touch manipulation time as described above, and the processor 130 may perform different functions according to the touch manipulation direction and touch manipulation time.

Specifically, the processor 130 may perform a function of reducing the helmet size during the touch time of the user touch manipulation when the touch direction of the user touch manipulation is in the first direction, and may perform a function of increasing the helmet size during the touch time of the user touch manipulation when the touch direction is in the second direction.

That is, the processor 130 may select and perform an operation of reducing or increasing the size of the helmet according to the direction of the user's touch manipulation, and may determine how much to reduce or increase the size of the helmet according to the time of the user's touch manipulation.

3C is a diagram for explaining that different functions are performed according to a touch direction and a touch time of a user touch manipulation according to an embodiment of the present invention.

Referring to FIG. 3C , a touch trajectory of a drag operation recognized by the touch pad 110 is shown.

Here, the first drag operation proceeds from the first start touch area 310 in the right direction 311 to the first end touch area 320. At this time, when the first drag operation proceeding in the right direction is input, the processor 130 detects that the moving direction of the first drag operation is to the right and performs an operation to reduce the size of the helmet. action can be performed.

In addition, the second drag operation proceeds from the second start touch area 330 in the left direction 331 to the second end touch area 340. At this time, when the second drag motion proceeding in the left direction is input, the processor 130 detects that the moving direction of the second drag operation is to the left and performs an operation to increase the helmet size. You can perform stretching operations.

As described above, the user can adjust the size of the helmet by performing a simple dragging operation on the touch panel 110 provided on the rear surface of the helmet size touch adjuster 100 according to an embodiment of the present invention, so user convenience can be maximized.

Meanwhile, the helmet size touch controller 100 according to an embodiment of the present invention may further include an LED lamp. Here, the LED lamp may emit light corresponding to the size of the helmet.

Further, the processor 130 may control the LED lamp to emit light in the first color while performing the function of reducing the helmet size, and control the LED lamp to emit light in the second color while performing the function of increasing the helmet size.

4A and 4B are diagrams for explaining an operation in which a color of a touch panel is changed according to a user touch manipulation according to an embodiment of the present invention.

Referring to FIG. 4A , when a first drag operation is performed on the touch panel 110, that is, when a touch operation proceeds from the first start touch area 310 in the right direction 311 to the first end touch area 320, the processor 130 may perform an operation to reduce the size of the helmet since the moving direction of the first drag operation is to the right, but may also perform an operation to reduce the size of the helmet in response to the dragging time during which the user touch is maintained. 0) may be controlled to emit light in the first color 410 .

That is, an LED lamp may be provided inside the touch panel 110, and the color of the surface of the touch panel 110 may be displayed differently according to the emission of the LED lamp.

For example, when the processor 130 performs an operation of reducing the size of the helmet according to the first drag operation, the LED lamp provided inside the touch panel 110 is controlled to emit red light, and accordingly, the touch panel 110 may also emit red light (410).

Referring to FIG. 4B , when a second drag operation is performed on the touch panel 110, that is, when a touch operation proceeds from the second start touch area 330 to the left direction 331 to the second end touch area 340, the processor 130 can perform an operation to increase the size of the helmet since the moving direction of the second drag operation is to the left.

For example, when the processor 130 performs an operation to increase the size of the helmet according to the second drag operation, the LED lamp provided inside the touch panel 110 is controlled to emit blue light, and accordingly, the touch panel 110 may also emit blue light 420.

As described above, by allowing the touch panel 110 to emit different light according to the operation of increasing or decreasing the size of the helmet, the user can easily recognize the touch panel 110 at night, thereby increasing user convenience.

Meanwhile, the helmet size touch adjuster 100 according to an embodiment of the present invention may further include a storage unit and a memory button unit to automatically adjust the helmet size according to the helmet size stored by the user.

5 is a block diagram showing the configuration of a helmet size touch controller according to another embodiment of the present invention.

Referring to FIG. 5 , the helmet size touch adjuster 100 according to an embodiment of the present invention may include a touch sensor 110, a pressure sensor 120, a processor 130, a storage unit 140, and a memory button unit 150.

Here, since the touch sensor 110, the pressure sensor 120, and the processor 130 have already been described, a detailed description thereof will be omitted.

Also, the storage unit 140 may store a fixed helmet size in a stopped state. Specifically, when the pressure sensed by the pressure sensor 120 is equal to or greater than a predetermined standard, the processor 130 stops adjusting the helmet size and fixes the helmet size in the stopped state. At this time, the processor 130 may store the helmet size in the stopped state in the storage unit 140.

And, when the memory button 150 is pressed, the processor 130 reads the information about the helmet size in the stopped state stored in the storage 140, and automatically adjusts the helmet size to the fixed helmet size in the stopped state.

Accordingly, the user can automatically adjust the size of the helmet to the size set when first wearing the helmet without performing separate adjustment of the size of the helmet every time.

6 is a view showing the outer shape of a helmet size touch controller according to another embodiment of the present invention.

Referring to FIG. 6 , a touch panel 110 and a memory button unit 150 may be provided on an outer surface of a helmet size touch controller according to another embodiment of the present invention, and a processor 130 may be included inside.

In addition, the memory button unit 150 may protrude to the outside and be pressed, and when the user presses the memory button unit 150, the processor 130 may automatically adjust the helmet size based on the fixed helmet size in the stopped state stored in the storage unit 140.

For example, when the memory button 150 is pressed, the helmet size touch controller 100 can adjust the first left and right support portions 650 and 660 connected to the helmet endothelium according to the fixed helmet size stored in the storage unit 140 in a stopped state, and can adjust the size of the helmet while adjusting the second left and right support portions 630 and 640 in contact with the user's head back and forth, and the third left and right support portion 61 connected to the strap or band of the helmet. 0, 620), you can adjust the helmet size by increasing or decreasing it.

In this way, when the memory button 150 is pressed, the processor 130 controls the first left and right supports 650 and 660, the second left and right supports 630 and 640, and the third left and right supports 650 and 660, respectively, to adjust the helmet size to match the helmet size stored in the storage unit 140, as described above.

7 is a block diagram showing the configuration of a helmet size touch controller according to another embodiment of the present invention.

Referring to FIG. 7 , the helmet size touch controller 100 according to another embodiment of the present invention may include a touch sensor 110, a pressure sensor 120, a processor 130, a storage unit 140, a memory button unit 150, and a fingerprint recognition unit 160.

Here, the fingerprint recognition unit 160 may recognize a user's fingerprint, and since a technology for recognizing a fingerprint is a known technology, a detailed description thereof will be omitted.

Also, when a user corresponding to the fingerprint recognized through the fingerprint recognition unit 160 is identified, the processor 130 can automatically adjust the size of the helmet based on the information of the identified user.

For example, the processor 130 may store fingerprints, user information corresponding to the fingerprints, and helmet sizes corresponding to the users in the storage unit 140 in the form of a look-up table, compare the fingerprint image recognized through the fingerprint recognition unit 160 with the stored fingerprint image to determine whether or not they match, and extract user information corresponding to the matched fingerprint image based on the look-up table to identify the user.

Further, the processor 130 may search for a helmet size corresponding to the identified user based on the lookup table, and accordingly, automatically adjust the helmet size to the helmet size corresponding to the identified user.

Of course, in this specification, the fingerprint recognition unit 160 has been described as an example, and it is described that a user is identified based on a fingerprint recognized through the fingerprint recognition unit 160, and the helmet size is automatically adjusted to the stored helmet size corresponding to the identified user.

Also, as described above, the operation process of identifying the user and adjusting the helmet size corresponding to the identified user may be performed through an application installed on the mobile device.

That is, for example, when a helmet-specific application installed on a user's mobile device is executed, user identification is performed through the helmet-specific application, and upon completion of user identification, the helmet-specific application transmits a helmet adjustment command to the helmet so as to adjust the helmet size corresponding to the identified user.
