In addition, as shown in Figure 2, the buckle unit 200 includes a receiving portion 210 in which the clip of the vehicle seat belt is accommodated.

When a more specific embodiment of the clip unit 100 is introduced, the clip unit 100 includes a clip part 110 to which a buckle of a vehicle seat belt is coupled and a pressure sensor 430 for sensing pressure applied to the vehicle. It includes a pressure sensor protection space 120 that can be accommodated.

The pressure sensor 430 detects a tensile force or a compressive force that is pulled by the clip part 110 coupled to the buckle of the vehicle seat belt or detects a pressure applied to the pressure sensor 430 directly to cause an accident. (Ultimately, the pressure applied to the vehicle is sensed.), and based on the pressure sensed by the pressure sensor 430, the user through the control module 500 and the communication module 600 The terminal automatically receives a report to a preset organization (eg, 119, 112) or a preset terminal, and also releases the coupling between the vehicle seat belt clip and the buckle unit 200 remotely.

As described above, the pressure sensor 430 needs to be safely protected from an accident in a configuration that detects an accident. As shown in FIG. 3, the present invention can realize this by providing the pressure sensor protection space 120 do.

The pressure sensor protection groove may be configured to be larger than the width of the pressure sensor 430 (configured as large as the pressure sensor protection space 120), and by being configured to be as large as the pressure sensor protection space 120 in this way, when a minor accident occurs It is possible to prevent damage to the pressure sensor 430 . That is, even when an accident occurs due to the damage of the pressure sensor 430, it is possible to prevent the automatic disconnection between the vehicle seat belt and the buckle unit 200 from being automatically released, and the impact caused by the accident can be prevented. It is possible to prevent the automatic release of the coupling between the vehicle seat belt and the buckle unit 200 remotely due to excessive detection of the pressure sensor 430 even in a non-impact shock.

And as shown in FIG. 4 or FIG. 6 , the buckle unit 200 includes a receiving part 210 , a locking member 220 and a button member 230 .

First, the receiving part 210 is where the vehicle seat belt clip is accommodated, as described above.

That is, by configuring the radius of the upper surface of the wall 223 to be shorter than the radius of the locking protrusion 221 , it is possible to prevent them from being abraded due to frequent rotation of the locking protrusion 221 , but also to the side surface of the wall 223 . It is possible to provide rotational stability through the support 224 provided with the protrusion.

Alternatively, the locking protrusion 221 may be positioned on the upper surface of the support 224 when the locking member 220 is in the unlocked state by allowing the rotation radius of the locking protrusion 221 only by 90 degrees.

And when an accident occurs and a pressure greater than a set value is sensed from the pressure sensor 430 , the locking control unit automatically releases the lock of the locking member 220 . In this case, the locking protrusion 221 exits the locking groove 237 by the motor 222 to release the lock of the locking member 220 , and the lifting control unit drives the linear motor 236 to drive the button member 230 can automatically descend.

However, it can be seen that the rotation radius of the locking protrusion 221 is smaller than the width of the locking groove 237 . In addition, the width of the locking groove 237 is obviously larger than the rotation radius of the locking projection 221 in order for the locking projection 221 to rotate smoothly within the locking groove 237 .

And, as shown in FIG. 7 , the locking part 231 is composed of a protrusion having an upward inclination toward the rear with respect to the insertion direction of the vehicle seat belt clip, and the button member 230 is exposed to the outside. The main body 233 having the pressing part 232 and the receiving part 210, the lower body 234 provided in the lower part of the main body 233, and the outer surface of the lower body 234 are coupled to and The upper end includes an elastic body 235 in contact with the lower surface of the main body (233).

And, as described above, as shown in FIG. 7 , the sensing module 400 is exposed toward the receiving part 210 , and the light emitting device 410 provided on one side and the other with the receiving part 210 as the center. It includes a light receiving sensor 420 provided on the side.

The light emitting device 410 located on the side of the buckle unit 200 may be composed of LEDs emitting various colors, and emit light when the vehicle seat belt clip is coupled to the buckle unit 200 and when not coupled. By changing the state, the vehicle occupant can determine the state of engagement with the buckle unit 200 . For example, it means that the light emitting device 410 emits light by changing a color or emits light by changing a light emission period.

And as described above, the present invention provides a lock control unit for controlling the locking member 220 and a determination unit for judging the fastening between the vehicle seat belt clip and the buckle unit 200 through the light reception of the light receiving sensor 420 . It includes a control module including a control module 500 and a communication module 600 for transmitting the data calculated by the control module 500 . And the control module 500 and the communication module 600 are provided on the upper surface and the vertical surface of the second inner step 340, as shown in FIG.

In addition, the control module 500 further includes an elevation control unit for driving the linear motor 236 .

And when the determination unit, the lock control unit, and the elevating control unit of the control module 500 are described in detail, the determination unit is the buckle through the communication module 600 when the light receiving sensor 420 receives a preset light. It notifies the user terminal that the unit 200 and the vehicle seat belt clip are coupled. Accordingly, the vehicle occupant can monitor the coupling state of the buckle unit 200 in real time.

In addition, it is possible to realize locking/unlocking remotely through the locking control unit and the elevating control unit. Specifically, when the locking control unit receives a remote locking command, as described above, the motor 222 of the locking member 220 is rotated so that the locking protrusion 221 is located in the locking groove 237 , so that the seat belt It is possible to prevent in advance the child or the elderly wearing the seat belt from unfastening the seat belt on their own. In addition, when a preset value is received from the pressure sensor 430, it is configured to be automatically released, so that it is possible to protect the occupants of the vehicle both when an accident does not occur or when an accident occurs.

In addition, the lifting control unit lowers the linear module when a remote release command is received through the communication module 600 . Of course, in this case, the lock control unit also receives a remote release command so that the insertion part 221b of the lock protrusion 221 escapes from the lock groove 237 .

And the case 300 constituting the outer surface of the present invention includes the first powder corresponding to the left case and the second powder corresponding to the right case. The first powder and the second powder each have four protrusions-groove structures are combined to form the case 300 , and the other parts are symmetrical left and right.

In addition, as shown in FIG. 5 , the second internal step 340 is provided with two in each of the first and second powders, so that a total of four can be provided. A portion near the vertex of the control module 500 . and has a 'L' shape to prevent movement of the front and rear surfaces of the control module 500 when an accident occurs.

And, as shown in FIG. 6 , the first powder includes an accommodation head 310 , an insertion head 320 , and a bent portion 321 .

First, the inner surface of the receiving head 310 and the outer surface of the insertion head 320 may have a corresponding shape and size, which can be coupled to each other even when the vehicle seat belt is short and cannot be coupled to the seat belt connector. This is to make it possible to completely combine it with the vehicle seat belt.

In addition, the accommodation head 310 completely surrounds the vehicle seat belt buckle when the vehicle seat belt buckle is coupled with the clip part 110 of the clip unit 100 to prevent them from being separated due to an external impact. there will be

Here, that the inner surface of the receiving head 310 and the outer surface of the insertion head 320 have a corresponding shape and size, the inner surface of the receiving head 310 is the insertion head 320 is the receiving It refers to having a size that can be inserted into the head 310, but having the same shape of the front cross-sections of each other. And in addition to this, when the insertion head 320 is coupled to the receiving head 310, the insertion head 320 has a shape and size corresponding to each other to the extent that there is no shaking within the inner surface of the receiving head 310. say to have

And the insertion head 320 further includes a curved portion 321 on the rear surface. Accordingly, when a vehicle seat belt is coupled to each of the clip unit 100 and the buckle unit 200, or when a vehicle safety belt is coupled to one side and another safety belt connector is coupled to the other side, an accident occurs However, it is possible to distribute the tensile force that may occur due to an external impact to the upper and lower sides, so that the coupling with the clip unit 100 or the coupling with the buckle unit 200 can be more firmly maintained.

And as described above, the detection module 400 is provided on the side of the clip part 110 and further includes a pressure sensor 430 for measuring an external force applied to the clip part 110, and the control module 500 is The control module 500 further includes an elevation control unit for driving the linear motor 236, and when a pressure equal to or greater than a set value is sensed from the pressure sensor 430, the lock control unit locks the locking member 220. is released, and the lifting control unit is configured to lower the button member 230 by driving the linear motor 236 .

Therefore, the vehicle occupant can monitor the coupling state with the buckle unit 200 in real time through the light receiving sensor 420, the light emitting device 410 and the determination unit, and the seat belt is connected to the buckle unit ( 200) and manual release (of course, it can also be remotely released through the lock control unit and the lift control unit on the contrary), and in case of an accident, the pressure sensor 430 and the lock control unit , is configured such that the vehicle seat belt and the buckle unit 200 are automatically separated through the elevating control unit.

Also, obviously, the control module 500 includes a circuit board, and the communication module 600 uses Wi-Fi, Bluetooth, and other mobile communication to control the control module 500, the detection module 400, and the user terminal (smartphone). ) to communicate with

On the other hand, the case 300 obviously needs to be strengthened because it is continuously exposed to external factors as the safety belt connector is protected, and the case 300 includes a coating film provided on the outer surface. can do.

This coating film is in contact with the case 300, but is provided on an adhesive layer that is softened at a first temperature or higher, and an intermediate layer that is provided on the adhesive layer and softens at a second temperature higher than the first temperature, and is provided on the upper part of the intermediate layer. It may include a protective layer that is softened at a third temperature higher than the temperature, and a heating layer that is provided between the adhesive layer and the intermediate layer to generate heat to the minimum value of the second temperature range.

This coating film prevents the occurrence of scratches through the protective layer, damage by external force, and cracks due to long-term continuous invasion, and in particular, removes the residual stress of the adhesive layer to thermal expansion and bending at the boundary with the case 300 external environment such as bending. It suppresses problems such as lifting and cracking, and furthermore solves the problem of peeling caused by the stress difference between the adhesive layer and the protective layer in the intermediate layer.

In a specific embodiment, first, the adhesive layer may include polybutylacrylate (PBA) and polymethyl methacrylate (PMMA). In order to minimize the difference in softening according to the temperature gradient, the thickness of the adhesive layer is preferably 0.020 mm to 0.150 mm.

Exemplarily, the adhesive layer may be a thermal impregnation of polybutyl acrylate and polymethyl methacrylate. The range of the first temperature, which is the softening temperature of the adhesive layer, is 90 to 100°C.

Next, the intermediate layer may include 200 parts by weight of a carboxylate acrylic copolymer based on 100 parts by weight of cellulose acetate butyrate. If the weight ratio is out of the above-mentioned weight ratio, the adhesive strength between the adhesive layer and the protective layer may be insufficient, and thus there may be a problem in that the film peels off. The second temperature range, which is the softening temperature of the intermediate layer, is 150 to 160°C.

Next, the protective layer may include 100 parts by weight of polymethylphenylsiloxane, 100 parts by weight of silicon-containing fiber, 100 parts by weight of silicon carbide, 3 parts by weight of manganese oxide, and 9 parts by weight of organosilicon-titanium compound.

In the protective layer, when polymethylphenylsilic acid is included in too little amount, there is a risk of softening due to heat generation of the heating layer due to a decrease in softening temperature, and when included too much, economic efficiency is reduced. The following protective layer compositions are based on 100 parts by weight of polymethylphenylsilic acid.

The silicone-containing fiber is added to impart water repellency, and its content is preferably 100 parts by weight. If it is less than 100 parts by weight, the water repellency is poor, and even if it is used in excess of 100 parts by weight, the effect of improving the water repellency is insignificant.

Silicon carbide is added to improve abrasion resistance, and its content is preferably 100 parts by weight. If it is less than 100 parts by weight, the abrasion resistance is reduced, and even if used in excess of 100 parts by weight, the effect of improving the wear resistance is not large.

The organosilicon-titanium compound is added to improve hardness and wear resistance, and the content thereof is preferably 9 parts by weight. At 9 parts by weight, the surface hardness improvement is most evident, and even if it exceeds this, the hardness improvement effect is insignificant.

The third temperature range, which is the softening temperature of the protective layer, is 650° C. or higher, so that it is not softened by heat of the heating layer, thereby providing strong surface protection performance. Additionally, the protective layer may further include functional additives such as a water repellent treatment agent and an anticorrosive agent.

Next, any heating layer may be used as long as it generates heat by application of electricity, and it is sufficient if the heating layer is heated to the minimum value of the second temperature, which is the softening temperature range of the intermediate layer. In a preferred embodiment, as for the exothermic temperature of the heating layer, the minimum value of the second temperature in the above example is 150° C., this heating layer may include polyacetylene and iodine, and the polyacetylene is a conjugated double bond in which electrons flow. Although there is no gap, it is possible to widen the gap by mixing different types of small molecules like iodine, so electrons flow and when electricity is applied, heat is generated due to electrical resistance.

The above-mentioned coating film is an adhesive layer in a situation in which residual stress such as compressive stress and tensile stress may be generated due to factors such as a difference in coefficient of thermal expansion with the case 300 , the surface shape of the case 300 , and bending due to an external force. The residual stress of the adhesive layer is removed so that the adhesion to the case 300 is excellent. In particular, as the heating layer generates heat, the adhesive layer is completely softened, the intermediate layer is partially softened, and the protective layer is not softened. After being removed, the intermediate layer has a small degree of softening, thus performing a role of crosslinking between the adhesive layer and the protective layer. That is, it is possible to effectively disperse and relieve the residual stress of the coating film while maintaining the physical and chemical properties of the protective layer.

Meanwhile, in the following, a smart seat belt system based on IoT will be described in detail.

According to some embodiments, the present invention provides a fastening for detecting the fastening between the clip unit 100 connected to one side of the belt, the buckle unit 200 connected to the other side of the belt, and the vehicle seat belt clip and the buckle unit 200 according to some embodiments.
