Generally, a seat belt installed on a vehicle or an aircraft is fixed on a seat as much as possible while the occupant is in operation, so that when the vehicle body or the like is about to stop in an emergency such as a collision accident, the driver or the occupant So as not to be thrown out to the outside of the vehicle or the like, thereby reducing a secondary injury that may be caused by an impact force due to inertia at the time of a collision.

That is, after the driver and the passenger are seated on the seat, the seat belt is configured to pull the belt toward the upper body and fasten the plate to the fastener in the buckle so as to fix the upper body of the occupant between the seat belt and the seat back.

However, in accidents such as the following example, a seat belt may be a problem.

A small aircraft belonging to the Taiwan Fusing Airlines flight in February 2015 crashed into the river more than an aircraft engine after the takeoff, resulting in more than 30 deaths. Passengers wearing seat belts could not escape from the water, There was a media report that all passengers who did not wear a belt were rescued. There has been controversy over whether the seat belt should be worn for a while in the media.

As described above, conventionally, when the automobile or the like has fallen into the river or the sea and has flooded, and the passenger has become embarrassed in the event of a fire or a collision, the passenger can not escape the seatbelt and can not escape or take a long time to rescue him.

In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

1 is a view schematically showing a configuration of an electronic seatbelt system capable of automatically releasing an emergency in accordance with an embodiment of the present invention.

Referring to FIG. 1, an electronic safety belt system 10 capable of automatically releasing an emergency includes a sensing sensor 100, a solenoid 200, an emergency battery 300, a timer 400, a seat belt switch 500, (600), and a smart device (700).

The electronic safety belt system 10 capable of automatically releasing an emergency in accordance with an embodiment of the present invention can automatically release the electronic safety belt 20 in an emergency such as collision, flooding or fire of the moving means 1. [ Here, the moving means 1 may include all the moving means of any structure capable of installing a seat belt in a seat such as an automobile or an airplane capable of moving a person by using power.

A plurality of detection sensors 100 may be installed on the moving means 1. [ The detection sensor 100 can sense at least one of shock, vibration, water or fire in an emergency or emergency such as collision, flooding or fire of the moving means 1. [

The detection sensor 100 may include a fire detection sensor 110, a water detection sensor 120, and a shock detection sensor 130. Here, the shock sensor 130 may be replaced with a vibration sensor, and both of the sensors may be used to sense impact or vibration.

The fire detection sensor 110 may be provided in the vicinity of the engine of the moving means 1. [ For example, when the moving means 1 is an automobile, the fire detection sensor 110 is located in a bonnet of an automobile and can detect fire or smoke when the fire occurs in the engine.

The water sensing sensor 120 and the impact sensing sensor 130 may be installed at predetermined positions near the seat belts of the respective seats. The water sensing sensor 120 can sense water when immersed. For example, the water detection sensor 120 may be provided on a floor such as a seat under a seat or an indoor floor in an automobile, but is not limited thereto. The impact sensor 130 may be provided on one side or the bottom of the seat. In some cases, the water sensing sensor 120 and the impact sensing sensor 130 may be mounted in the seat belt buckle 21.

Fig. 2 is an exploded perspective view schematically showing the electronic seatbelt of Fig. 1, Fig. 3 is a side sectional view showing a state in which the electronic seatbelt of Fig. 1 is fastened, and Fig. Fig. 3 is a side cross-sectional view showing the state of the state.

2 to 4, a solenoid 200 may be provided in the buckle 21 of the electronic seat belt 20 of each seat. The solenoid 200 can be operated under the control of the electronic control unit 12 that has received signals from the respective sensors 100. Specifically, the solenoid 200 can pull the slide knob 25 to lift the fastener 22 coupled with the plate 23 and detach the fastener 22 while retracting. Thus, the solenoid 200 can release the plate 23 from the fastener 22. That is, the solenoid 200 separates the plate 23 and the buckle 21 in an emergency or emergency so that the electronic seat belt 20 can be released.

The solenoid 200 is configured to pull the slide housing (not shown) to lift the fasteners 22 associated with the plate 23 and to disengage the fasteners 22 from the plate 23 It is possible.

The solenoid 200 is maintained in an OFF state when the plate 23 and the buckle 21 are coupled and then automatically turned on when water, fire, impact, or the like is detected from the respective sensors 100 So that the solenoid 200 is operated and the plate 23 and the fastener 22 can be separated.

Accordingly, the present invention utilizes an electronic seat belt 20 that can be released by driving a solenoid 200 that operates by electric force, and a plate, which is a conventional seat belt fastening means, and a buckle.

Also, as another embodiment, the solenoid 200 may replace its role with a geared motor.

2 to 4, the buckle 21 of the electronic seat belt 20 of the present invention includes a fastener 22, a slide knob (not shown) 25, a fastening portion 26, an elastic body 27, a connecting member 28, a solenoid 200, and the like.

The solenoid 200 may be connected to the rear end 25a of the slide knob 25 through the connecting member 28. [ The connecting member 28 can transmit the driving force of the solenoid 200 driven when the power is supplied to the slide knob 25. The slide knob 25 is a structure corresponding to a press button of a buckle opening in a conventional seat belt. In general, the slide knob 25 is slid inward through a pressing operation so as to release a plate in a coupled state.

A fastening portion 26 may be provided at a lower portion of the buckle 21 to allow the plate 23 to be inserted therein. The fastening portion 26 may be provided with a hook-shaped fastener 22. The combination of the plate 23 and the fastener 22 can be achieved by inserting the plate 23 into the buckle 21 so that the fastener 22 spans the plate hole 23a formed in the plate 23. [

A separate elastic body 27 such as a spring is connected to the rear of the fastening hole 22 so that the plate 23 is engaged in the buckle 21 and the elastic body 27 is contracted. It is possible to generate a restoring force toward the inlet side. That is, when the fastener 22 is detached from the plate hole 23a, the plate 23 is separated from the buckle 21 because the plate 23 is always separated from the buckle 21 by the action of the elastic body 27 The elastic force of the outward direction is received.

In the buckle (21), a slide knob (25) may be provided on the upper portion of the fastening portion (26). The slide knob 25 is moved backward by the solenoid 200 to retract the fastener 22 while contracting the elastic body. Depending on the embodiment, the fasteners 22 may be lifted and pulled back, or simply retained in the lifted state.

The operation of the solenoid 200 causes the slide knob 25 to be pulled toward the solenoid 200 or backward so that the slide knob 25 is pulled to pull the fastener 22, And can be separated from the sphere 22.

According to the embodiment, an elastic member may be additionally or alternatively connected between the rear end of the slide knob 25 and the solenoid 200 instead of the connecting member 28. The elastic member may be a spring or the like. Such an elastic member can provide a restoring force when the slide knob 25 is moved backward by the solenoid 200 and then returned to the front.

The rear slide knob 25 can be returned to the original position in front by the operation of the solenoid 200 through the connecting member 28. [

The emergency battery 300 can supply power to the electronic control unit (ECU) 12 and the solenoid 200 when the commercial power (battery) is disconnected in an emergency or in an emergency. Emergency battery 300 may include both a rechargeable or replaceable battery (battery) that is normally charged from a commercial power source (battery).

The emergency battery 300 can be provided in case of interruption of the power supply due to breakage of the commercial power source (battery) of the moving means 1 due to an accident such as collision, immersion, fire or the like. That is, usually, the seat belt is operated by the commercial power source (battery) of the moving means 1, but only when the fire, flood, shock or the like is detected and the commercial power source (battery) So that the solenoid 200 can be operated.

Further, the solenoid 200 can be sequentially operated for each seat in which the electronic safety belt 20 is installed in an emergency. For example, referring to FIG. 1, in a typical automobile, each solenoid 200 in each electronic seat belt 20 may be operated in the order of the driver's seat, the passenger's seat, the rear seat 1, the rear seat 2, It goes without saying that this order can be arbitrarily changed.

This prevents the situation where the power supply of the emergency battery 300 is temporarily shortened because the solenoid 200 of each of the electronic safety belts 20 is simultaneously driven and the capacity of the emergency battery 300 is reduced It is to be able to keep it.

The electronic control unit 12, the solenoid 200, the emergency battery 300, the impact sensor 130, and various switches 500 and 600 described later are waterproofed so that they can be operated even when they are submerged in water desirable.

In addition, referring to FIG. 1, an electronic control unit 12 and an emergency battery 300 may be provided in a control box according to an embodiment of the present invention. The control box may be installed at a predetermined position near the electronic safety belt 20. [ Alternatively, the electronic control unit 12 and the emergency battery 300 may be installed separately from each other. Optionally, the emergency battery 300 may be mounted in the buckle 21 of the electronic seat belt 20.

The timer 400 can generate a driving signal of the solenoid 200 after a predetermined time elapses or immediately after a sensing signal such as a shock (vibration), water, or fire is inputted from each sensing sensor 100.

For example, when an impact accident occurs with an object while the vehicle is running, when the impact sensor 130 senses the initial impact and the set time (s) on the timer 400 is exceeded, Can be released. If the set time on the timer 400 is 5 seconds, if the second and third shocks are detected again within 5 seconds after the impact detection, the counted time s becomes '0' (reset) The electronic seat belt 20 can be automatically released when the time counted for 5 seconds is exceeded.

In addition, if the vehicle 1 falls into the river or the sea due to an unexpected accident during the operation of the moving means 1, the electronic seatbelt 20 is automatically released after the setting time (s) after the first shock detection is exceeded. s, the electronic seat belt 20 can be automatically released immediately upon detection of a signal from the fire detection sensor 110 or the water detection sensor 120.

That is, the timer 400 generates a solenoid 200 driving signal when a signal of the fire detection sensor 110 or the water detection sensor 120 is sensed after a predetermined time from the input of the signal of the impact detection sensor 130 .

The drive signal of the timer 400 may be transmitted to the electronic control unit 12 to operate the solenoid 200 in each electronic seat belt 20. [

The seat belt switch 500 may be connected to the ON state when the plate 23 and the fastener 22 are engaged in the buckle 21 of the electronic seat belt 20. [

The seat belt switch 500 is a switch whose switch contact is changed in accordance with whether or not the plate 23 of the electronic seat belt 200 is engaged with the buckle 21. When the plate 23 and the buckle 21 are engaged And can be displayed on the instrument panel of the moving means 1 or the like.

That is, the seat belt switch 500 can be switched to the ON state when the passenger normally wears the electronic seat belt 20.

The electronic safety belt system 10 capable of automatically releasing an emergency in accordance with an embodiment of the present invention can be operated in a state in which the safety belt switch 500 is turned ON.

That is, in the present invention, the solenoid 200 in the buckle 21 of each seat-mounted electronic seat belt 20 according to the operation of the fire detection sensor 110, the water detection sensor 120 or the impact detection sensor 130 The drive is operable when the plate 23 of the electronic seat belt 20 and the buckle 21 are engaged and the seat belt switch 500 is connected in the ON state.

The manual switch 600 is provided in the buckle 21 of each electronic seat belt 20 so that the solenoid 200 can be actuated to release or separate the fastener 22 from the plate 23 during the pressing operation of the occupant have. That is, the manual switch 600 allows the electronic seat belt 20 to be conveniently used in a touch manner, not in an emergency. When the manual switch 600 is used, a general commercial power source of the moving means 1 can be used.

For example, the manual switch 600 may be installed at the entrance of the buckle 21 of the electronic seat belt 20 into which the plate 23 is inserted. According to one example, the manual switch 600 may be located on the push button of a conventional mechanical seat belt. This manual switch 600 is provided in a one-touch manner to facilitate disengagement of the electronic safety belt 20. [ The manual switch 600 is also turned ON by pressing the solenoid 200 to activate the electronic seat belt 20. Such a manual switch 600 can be viewed as a way of utilizing the existing mechanical seat belt structure in order to easily operate the seat belt in everyday life, not in an emergency or emergency.

Therefore, the electronic seat belt 20 according to the present invention can be released from the seat belt mechanically through a normal push button, as well as electronically releasing the seat belt via the manual switch 600.

As described above, the present invention is advantageous in that the manual switch 600 can be automatically released even if the user manually presses the manual switch 600 with a simple one-touch operation.
