The press switch 103 may generate various signals such as a short press signal, a long press signal, and a number of press signals within a specified time (eg, 3 seconds).

The motion sensor 104 may use ultrasonic waves, infrared rays, or the like. The motion sensor 104 is used to determine an emergency situation when the residence is collapsed and no movement (ie, motion) is detected. The motion sensor 104 detects the movement of the occupant and may mistake the resident as having no abnormality. So, the detection angle of the motion sensor 104 is small, and the emergency call bell 100 is above a certain height (that is, the resident is detected, and the pet on the floor is detected in the entrance hall, the kitchen, in front of the TV, etc. where the resident frequently moves. height), this problem of the motion sensor 104 can be solved.

The illuminance sensor 105 detects when there is no change in illuminance in the living space, that is, when there is no change in illuminance that occurs while living by a resident, such as lighting or TV light, to determine an emergency situation, and The temperature sensor 106 detects that the temperature is too high or low for the resident to live while considering the seasonal factors to determine an emergency situation, and the humidity sensor 107 is also too high for the resident to live in. It detects a high or low level so that an emergency can be identified.

The emergency call bell 100 has a unique number, and a unique number of each emergency call bell 100 is registered in the cloud server 200 .

Therefore, when the power is turned on, the emergency call bell 100 notifies that the LTE module 101 is activated as the cloud server 200, and the emergency call system starts to operate immediately. That is, the emergency call bell 100 is a 'plug and play' type, and the user who purchases the emergency call bell 100 operates immediately when power is applied to the emergency call bell 100 without a separate operation. However, when the user purchases the emergency call bell 100 , the user provides information such as his or her name, contact information, and the name and contact information of a family member to whom the emergency situation is to be spread to the seller, and the seller registers it in the cloud server 200 . is needed

In the database 230, the unique number (ID) of the emergency call bell 100, the information of the emergency call bell 100 user, information of the family to send the text message, the phone number of the person concerned to send the text message, the content of the text message to be sent, etc. matched and registered.

A user or his/her family may access the database 230 using a terminal equipped with a dedicated application or the Internet after membership registration to register and modify information such as a phone number and message content. For example, in response to a signal that the user presses the pressure switch 103 of the emergency call bell 100 once, the information in the database 230 is stored so that a text message 'I'm doing well, don't worry' is sent to the phone number of Family 1 After registering, for the signal to press the pressure switch 103 twice, 'Emergency' to Family 2 and 119. Information may be registered in the database 230 so that a text of 'Please come quickly' is sent.

When a text transmission request is received from the cloud server 200, the text sending server 300 sends the requested message to a corresponding phone number.

Hereinafter, the mechanical structure of the emergency call bell 100 will be described with reference to FIGS. 2 to 3 .

The emergency call bell 100 includes a lower case 120 , a middle case 130 , an upper case 140 , a spring 150 , and control boards 161 and 162 .

The lower case 120 has an open top structure, a pressing protrusion 121 is protruded from the center of the inner bottom, and a hook protrusion 122 and a guide protrusion 123 are formed around the pressing protrusion 121 . The protrusion is formed, and the support protrusion 124 is protruded around the hook protrusion 122 and the guide protrusion 123 .

The contact pad 125 is in close contact with the outer bottom of the lower case 120 to seal the gap. The adhesive pad 125 can be fixed by attaching the lower case 120 to the table or the like while sealing the gap using double-sided tape.

The middle case 130 is mounted on the lower case 120 so as to move up and down.

The upper portion of the middle case 130 has an open structure, and an exposed hole 131 is formed in the center of the bottom.

At the outer bottom of the middle case 130 , around the exposed hole 131 , the hook protrusion 122 of the lower case 120 and the hook tuck 132 are hook-coupled to the upper part of the hook tuck 132 . A guide groove 133 for guiding the elevating and lowering of the hook protrusion 122, and a guide groove 134 for guiding the elevating and lowering of the guide protrusion 123 are inserted, are formed around the guide groove 134. The support protrusion 135 is formed to protrude.

Control boards 161 and 162 are embedded in the middle case 130 . The control boards 161 and 162 include a first board 161 and a second board 162 .

The pressure switch 103 is mounted in the center of the lower surface of the first board 161 , and the pressure switch 103 is disposed to protrude downward from the exposed hole 131 .

When the pressure switch 103 is covered with the cap pad 136 , the cap pad 136 seals the exposed hole 131 . The edge of the cap pad 136 is pressed into close contact with the inner bottom of the first board and the middle case 130 .

An LED, a motion sensor 104, an illuminance sensor 105, a temperature sensor 106, and a humidity sensor 107 are mounted on the first board 161, and the LTE module 101 is mounted on the second board 162. and the SIM chip 102 are mounted.

The upper case 140 covers the upper opening of the middle case 130 .

Bosses 141 that are fastened to the middle case 130 of the upper case 140 with bolts 142 are formed to protrude. An O-ring 143 is inserted into the bolt 142 fastened to the boss 141 to seal the fastening gap.

A sealing ring (R) is interposed on the contact surface of the upper case 140 and the middle case 130 to seal the gap therebetween. A seating groove 134 in which the sealing ring R is seated is formed in the upper portion of the middle case 130 , and when the bolt 142 is fastened to the boss 141 , the upper case 140 is connected to the sealing ring (R) is pressed to close the gap.

The spring 150 is accommodated and supported in the support protrusion 124 of the lower case 120 and the support protrusion 135 of the middle case 130 at the lower part and the upper part, respectively, so that the middle case 130 is The lower case 120 is elastically supported so as to ascend and descend on the upper case.

The spring 150 elastically supports the middle case 130 in a wide range of diameter corresponding to about half the diameter of the middle case 130, and the hook protrusion 122, the guide protrusion 123, and a guide groove ( 133) and the guide groove 134 stably guide the elevating and lowering of the middle case 130, so that even when an edge deviating from the center of the upper case 140 is pressed, the middle case 130 closes to a straight line while suppressing bias. Since it descends, it is possible to prevent the pressure switch 103 from not operating.

The O-ring, which is mainly used as the sealing ring (R), may not completely seal the gap, wear out due to repeated use, and naturally lose elasticity over time.

Accordingly, the present invention uses a quad ring (R) as a sealing ring (R) to more completely seal the gap between the middle case 130 and the upper case 140, and introduces an elastic deformable member (E).

Hereinafter, the quadring (R) of the present invention will be described in more detail with reference to FIG. 5 .

The quad ring (R) has lip portions (R1) formed by protruding an arc-shaped corner portion of a square cross section, a fitting hole (R2) formed in the longitudinal direction at the center of the lip portions (R1), and the fitting hole (R2) It is made to include an insertion groove (R3) formed by opening to one side of the.

The elastic deformable member (E) has a circular elastic ring portion (E1) in close contact with the inner circumferential surface of the fitting hole (R2), and the elastic ring portion (E1) is crossed in an 'X' shape at both ends of the insertion groove (R3) ) and a connecting portion E2 connected to be fitted, and a pressing portion E4 connected to the outer end of the connecting portion E2 to protrude from the lip portion R1 and placed on the bottom of the seating groove 134 .

When the protruding portion of the quad ring R seated in the seating groove 134 of the middle case 130 is pressed against the cover 16, the bottom of the seating groove 134 presses the pressing portion E4. While pressing, the elastic ring part E1 is opened, and the lip part R1 protruding out of the seating groove 134 is expanded to more strongly press and adhere to the surface of the cover 16 . When the pressing part E4 is pressed, the connecting part E2 crossed in an 'X' shape spreads the elastic ring part E1.

Here, the quad ring (R) is stretched left and right when the upper portion is pressed and pressed based on FIG. is not pressed, but rather the quad ring (R) is pressed sideways by the force that is blocked on the wall surface of the seating groove 134 and acts as a squeezing force, so that the interval between the insertion grooves (R3) is narrowed.

When the spacing between the insertion grooves R3 is narrowed, the spacing between the two extension portions E3 of the elastically deformable member E is also decreased and the diameter of the elastic ring portion E1 is increased. When the diameter of the elastic ring part (E1) is expanded, the lip part (R1) outside the seating groove (134) is also expanded by that much.

In the quad ring R, the outer surface of the concave portion between the lip portions R1 is cut by the insertion groove R3, so that the lip portions R1 may be spread around the fitting hole R2.

A plurality of the insertion grooves R3 are arranged to be spaced apart from each other by a predetermined interval along the fitting hole R2.

The elastic deformable member (E) is mounted with an elastic ring portion (E1) having a circular ring shape corresponding to the quad ring (R) fitted into the fitting hole (R2) in the form of a pipe, and at this time, along the elastic ring portion (E1) The connecting portion E2 and the pressing portion E4 are connected to be arranged to be spaced apart from each other by a predetermined interval.

In addition, the connecting part (E2) and the pressing part (E4) are connected by an extension part (E3) formed longer than the distance between the inner peripheral surface of the fitting hole (R2) and the outer peripheral surface of the lip part (R1), the elastic deformable member (E) When mounted on the fitting hole (R2) of the quad ring (R), the pressing portion (E4) exposed to the insertion groove (R3) protrudes more than the outer surface of the lip portion (R1). Here, the pressing part (E4) protrudes more than the outer surface of the lip part (R1), so when pressing the upper lip part (R1) based on FIG. 5, the quad ring (R) may temporarily descend, but As a result, the lower lip portion R1 is engraved and the upper lip portion R1 is expanded by the elastic ring portion E1, thereby increasing the range in which the upper lip portion R1 elevates.

In the above description of the present invention, an LTE emergency call system having a specific shape and structure has been described with reference to the accompanying drawings, but the present invention is capable of various modifications and changes by those skilled in the art, and these modifications and changes are the It should be construed as belonging to the scope of protection.
