It may further include an impact reducing unit (100, see reference numeral '200' in FIGS. 6A and 6B and reference numeral '400' in FIG. 7 ) that operates to

Some 100,200 of the shock reducing units 100,200,400 may operate based on a value detected by a drop detection unit (not shown) provided inside the body 11 and detecting the fall of the body 11. .

More specifically, although not shown in the drawing, the fall detection unit may include an acceleration sensor that converts the motion of the body 11 into an acceleration value and recognizes it.

In addition, the main body 11 may further include a gripping sensor 7 that senses a user's gripping of the main body 11 . The grip sensor 7 is a touch sensor or an electrostatic sensor provided in either the lower case 12 or the upper case 13 of the main body 11, and can be provided to electrically sense grip through the user's hand. there is. However, the gripping sensor 7 is not necessarily limited to a touch sensor or an electrostatic sensor, and may be provided as a pressure sensor.

4A and 4B are side cross-sectional views showing air pockets before and after air injection, FIGS. 5A and 5B are front cross-sectional views showing air pockets before and after air injection, and FIGS. 6A and 6B are A side cross-sectional view showing before and after detachment of the detachable battery by the battery removal unit, and FIG. 7 is a side cross-sectional view showing the repulsive force generating unit provided inside the main body among the configurations of FIG. 1 .

As referred to in FIGS. 4A to 7 , the shock reducing units 100, 200, and 400 include an air pocket unit 100 provided to be expandable and deployable between the inner surface of the main body 11 and the main mount 80, and a removable battery ( 300 may include at least one of a battery removal unit 200 that separates the body 11 from the main body 11 and a repulsive force generating unit 400 provided between the inner surface of the body 11 and the main mount 80 .

First, the air pocket unit 100, as shown in FIGS. 3, 4a and 4b, expands when air is injected and contracts when air is discharged, and air in the air pocket 110. It may include an air filling control unit 120 for injecting and discharging.

The air pocket 110 is provided with at least one of an elastic material (rubber) and a fabric material, and the volume can be expanded by air supplied through the air filling control unit 120, and the air filling control unit 120 The volume can be reduced by the air discharged through. That is, the air pocket 110 may be provided with at least one of an elastic material or a fabric material that reduces impact between the inner surface of the main body 11 and the main mount 80 .

Here, the air pocket 110 may be designed to be located in a gap formed between the inner surface of the body 11 and the main mount 80. For example, as referenced in FIGS. 3, 4A and 4B, the air pocket 110 is the inner surface of the lower case 12 in which the scanning electrical part is mainly disposed in the main body 11 and the main mount ( In addition to being disposed between the lower surfaces of the lower surfaces of the 80), some may be extended forward to cover the lower side of a portion provided with an optical member such as the camera lens 20, and some may be disposed to cover the left and right side portions of the main mount 80. A plurality of them extend toward the main mount 80 and may be arranged to cover the scanning electric part coupled to the side part of the main mount 80 .

As shown in FIG. 5A, the air pocket 110 is contracted in the lower and side portions of the main mount 80, and then, as referenced in FIG. 5B, the air pocket by the air filling controller 120 ( 110), the lower and side portions of the main mount 80 are inflated in the vertical and horizontal directions, respectively, to protect the scanning electric unit and the optical member from impact.

The expansion pressure of the air injected into the air pocket 110 has the purpose of protecting the scanning electrical unit or optical member from external impact, and is at least a level of expansion pressure at which the scanning electrical unit or optical member is not lost due to expansion. It can be designed to be inflated.

In addition, the air pocket 110 may be designed to be contracted to a very thin thickness before expansion to facilitate the flow of air introduced by the intake fan 95 in the inner space of the main body 11.

Here, the air filling control unit 120 may be provided in the form of an air pump that generates and injects a predetermined amount of compressed air. When compressed air is injected into the air pocket 110 by the air filling control unit 120, the air pocket 110 expands in the inner space of the main body 11 according to the amount of injected compressed air and acts as a shock reducing unit. function can be performed.

On the other hand, the air filling control unit 120 can replace its function with the above-described intake fan 95, and the air pocket 110 is not shown in the drawings, but is disposed on the inner surface and the inner space of the main body 11 It may be disposed in close contact with the entire inner surface of the body 11 corresponding to the rest except for the connection portion of the configured configuration (eg, the scanning electric unit and the optical member).

Here, the air injection part of the air pocket 110 is disposed on the air flow path at the rear end of the main body 11 into which external air is introduced by the intake fan 95, and the air discharge part of the air pocket 110 is It is disposed on the air flow path at the front end of the body 11 in which the probe tip 14 is provided, and the air introduced from the outside by the suction force of the intake fan 95 is introduced into the air injection part of the air pocket 110. When air is injected through the air pocket 110, the air may flow into the air pocket 110 and expand with a predetermined inflation pressure.

In this case, since the air pocket 110 can be inflated only by the intake force of air by the intake fan 95, there is no need to provide an air filling control unit 120 such as an air pump that generates separate compressed air. , Since the flow of air in the inner space of the main body 11 is possible, it has an advantage of performing a continuous heat dissipation function. In addition, since it always functions as an impact reducing unit during intake operation of the intake fan 95, it has an advantage of not requiring a separate fall detection unit.

In this case, the air pocket 110 may be provided with a 3D matrix fiber yarn material that is easily restored to its original shape after expansion.

On the other hand, when the fall detection unit is provided with an acceleration sensor, when the acceleration value of the main body 11 recognized by the acceleration sensor is greater than the set value and the gripping sensor 7 detects that the user's grip is not an air pocket. The unit 100 can be operated. That is, when the user does not dig the main body 11 and the main body 11 moves above a predetermined acceleration value, the main body 11 suddenly falls regardless of the user's will, so for example, impact The air pocket unit 100 of the reducing unit may be operated to protect the scanning electric unit and the optical member inside the main body 11 from external impact.

Conversely, even if the main body 11 moves at a predetermined acceleration value or more, and even if the main body 11 is detected as falling by the fall detection unit, when the user grips the main body 11 again or the user In the case of continuously gripping the main body 11 (ie, when the user's grip is detected by the gripping sensor 7), the air pocket unit 100 is not operated.

However, the air pocket unit 100 does not necessarily have to be operated by the detection value (eg, acceleration value) of the fall detection unit, and when the power is turned ON by the power button unit 5, the air charging control unit 120 It is also possible to inject air into the air pocket 110 through the air pocket 110 to prepare for an impact caused by an unexpected drop of the main body 11 while the user continues the scanning process.

In this case, when the power is turned off by the power button unit 5, air can be discharged from the air pocket 110 through the air charging control unit 120. In this way, when the air is discharged from the air pocket 110 by the air charging control unit 120, the air charging control unit 120 of the main body 11 so that the additional air discharge operation by the power supply can be made. The power may be designed to turn off the power after a predetermined time elapses after the power button unit 5 is turned off.

Since the air pocket 110 of the air pocket unit 100 is concerned about poor operation due to the occurrence of fine holes during repeated expansion or contraction processes, the inside of the main body 11 is easily replaceable by the user. It may be provided detachably to. In this case, it goes without saying that coupling to the air charging control unit 120 can also be performed by a simpler detachable coupling method.

The information on the number of falls detected by the fall detection unit may be stored separately and then notified to the user through a user program (eg, a scanner interlocking application) linked with the handheld type scanner 1 . The handheld type scanner 1 according to the present invention provides the advantage of being able to call the user's attention to use only by providing the above-described fall count information to the user.

Here, when the fall of the handheld type scanner 1 is sensed by the fall detection unit, when the falling handheld type scanner 1 is provided as an intraoral scanner that needs to be inserted into the oral cavity of the patient to be treated, For hygiene protection, the user is recommended to disinfect the product through a user program, or if the handheld type scanner 1 is equipped with its own UV disinfector, UV disinfection can be performed.

On the other hand, the battery detachable unit 200 among the shock reducing units 100, 200, and 400, as referred to in FIGS. 3, 6A, and 6B, attaches a removable battery 300 prepared to supply power to the scanning electrical unit to the main body 11 ) This is an embodiment in which external impact is reduced by separating from

More specifically, as shown in FIG. 3 , a removable battery 300 may be further provided at the rear end of the main body 11 and supplying a predetermined power.

While the handheld type scanner 1 is manufactured to be lightweight and compact in order to improve user portability and usability, an external power source (not shown) is used as a power source in that a relatively large amount of power is consumed during the patient's oral cavity scanning process. It may be connected to and supplied from the main body 11 through a cable (not shown), or may be provided as a removable battery 300 that is detachably coupled to the main body 11 to directly supply power without a separate power cable.

When the removable battery 300 is coupled to the main body 11, as the weight of the main body 11 increases due to the characteristics of the battery, the external shock caused by the fall of the main body 11 also increases by the weight of the removable battery 300. A larger impact can be applied to the scanning electric unit or the optical member inside the main body 11 .

Accordingly, when the fall of the main body 11 is sensed by the fall detection unit, the battery removal unit 200 instantly separates the removable battery 300 from the main body 11 to lower the overall weight of the main body 11. It plays a role in reducing the amount of impact.

More specifically, as shown in FIGS. 6A and 6B, the battery removal unit 200 includes at least one solenoid box 210 provided at a joint between the removable battery 300 and the main body 11, At least one solenoid rod 220 pushing one side of the removable battery 300 inside the solenoid box 210 may be included.

The solenoid rod 220 may be configured to push one surface of the removable battery 300 so that coupling of the removable battery 300 to the main body 11 is released by moving in a linear direction.

When the removable battery 300, which occupies a relatively large weight, is separated from the main body 11, as the amount of external impact on the main body 11 decreases, the scanning electric unit and the optical member installed in the inner space of the main body 11 It also has the effect of reducing the amount of impact transmitted.

Among the shock reducing units 100, 200, and 400, the air pocket unit 100 and the battery removal unit 200 correspond to an embodiment that operates in conjunction with the detection value of the drop detection unit, but among the impact reducing units 100, 200, and 400, the repulsive force generating unit 400 ) is an embodiment that is disposed between the inner surface of the main body 11 and the main mount 80 to reduce the external impact of the main body 11 at all times regardless of the detection value of the drop detection unit.

More specifically, as shown in FIG. 7 , the repulsive force generator 400 is attached to at least one first magnet 410 attached to the inner surface of the main body 11 and the main mount 80, It may include at least one second magnet 420 attached to face the at least one first magnet 410 .

Here, the first magnet 410 and the second magnet 420 may be permanent magnets arranged to form mutual repulsive force. However, the first magnet 410 and the second magnet 420 do not necessarily have to be provided as permanent magnets, and it is natural that they may be provided as electromagnets to the extent that their polarities are electrically controlled. When the first magnet 410 and the second magnet 420 are provided as electromagnets, it is natural that they can be interlocked and controlled based on the detection value of the drop detection unit.

The first magnet 410 and the second magnet 420 are disposed at a distance that generates a mutual repulsive force, and although not shown, are fixed to a filling material that fills the gap between the inner surface of the main body 11 and the main mount 80. It can be. Therefore, when a predetermined shock is transmitted from the outside of the main body 11, the external shock is primarily absorbed by the filler, and the repulsive force formed between the first magnet 410 and the second magnet 420 causes a second shock. The external impact may be gradually reduced.

In this way, the handheld type scanner 1 according to an embodiment of the present invention has an air pocket unit 100 and a battery removal unit 200 implemented in the form of impact reducing units 100 and 200, so that the main body 11 External impact through the impact reducing unit 400 implemented in the form of a repulsive force generating unit 400 that reduces the impact caused by the fall of the object and reduces the impact transmitted to the scanning electronic unit and the optical member while generating a mutual repulsive force. Since can be reduced, it provides an advantage of preventing damage to relatively expensive components (scanning electronic parts and optical members).

In the above, the handheld type scanner 1 according to an embodiment of the present invention has been described in detail with reference to the accompanying drawings. However, it should be taken for granted that the embodiments of the present invention are not necessarily limited by the above-described embodiment, and various modifications and implementation within the equivalent range are possible by those skilled in the art to which the present invention belongs. will be. Therefore, it will be said that the true scope of the present invention is determined by the claims described later.
