Additionally, the control unit (E) may include a CPU, memory, and sensor controllers, and the memory capacity may increase depending on various additional functions of the vehicle. Manual transmission vehicles have an average capacity of 256KB~2MB, automatic transmission vehicles have an average capacity of 4~8MB, and the Siemens CPU can have a processing speed of 8~16 bits and 2.2~8MHz.

Therefore, the buckle locking system 10 using the magnet 240 according to an embodiment of the present invention controls the locking unit 200 using magnetic force, which will be described later, on the frame unit 100 through the control unit (E), The tongue (T) of the seat belt and the buckle may be provided so that they cannot be released during operation.

The control unit (E) having the above-described configuration monitors the locking state of the tongue (T) in real time when the driving of the vehicle is confirmed, and when the tongue (T) is unlocked by an external force, the occupant's It may be arranged to send a warning alarm to a mobile terminal or nearby government office.

As shown in FIG. 2, the buckle locking system 10 using a magnet 240 according to an embodiment of the present invention may largely include a frame unit 100 and a locking unit 200.

First, the frame unit 100 may be provided so that the tongue (T) of the seat belt can be inserted and withdrawn in one direction.

Here, the shape, structure, material, etc. of the frame unit 100 may vary as long as the tongue (T) of the seat belt is retracted in one direction and the seat belt can be unfastened by being withdrawn in the opposite direction, which may result in the present invention. It would be natural to say that the scope of rights is not limited.

However, for more detailed explanation, if an example is given, the frame unit 100 may have an internal space and a through hole, that is, a locking hole 110, which will be described later, may be formed on one side of the outer circumferential surface.

Additionally, the frame unit 100 may be provided with an ejector 120 at the inner lower portion to press the tongue T in the direction in which it is pulled out from the frame unit 100 at the lockable position L1, which will be described later.

Additionally, the frame unit 100 may be provided with a button 140 on the inner upper portion that can be pressed by the rider to release the fastening of the tongue (T) and the buckle.

Accordingly, the locking unit 200 can be returned to the lockable position L1 by being pressed downward from the locking position L2, which will be described later, by the button 140 provided on the top of the frame unit 100.

Next, the locking unit 200 can fix or unfasten the above-described tongue (T) to the inside of the frame unit 100 through magnetic force.

Specifically, the locking unit 200 is linked with the control unit (E) described above, keeps the tongue (T) in a locked state when the control unit (E) confirms that the vehicle is running, and locks the tongue (T) in a locked state when the vehicle's engine is turned off. It can be arranged so that the lock state can be released by.

Specifically, the locking unit 200 using magnetic force may include a lock bar 220 and a magnet 240 as shown in FIG. 3 .

First, the lock bar 220 moves toward the tongue (T) inside the frame unit 100 and fixes the tongue (T) in the locking position (L2), or moves to the unlocking position (L3) and locks the tongue (T). It can be arranged to release the bond.

When the driving of the vehicle is confirmed through the above-described control unit (E), the magnet 240 forms magnetic force in one direction under the control of the control unit (E), thereby fixing the lock bar 220 in the locking position (L2). .

In addition, the magnet 240 forms the direction of magnetic force in the opposite direction to one direction when the vehicle's engine is turned off, allowing the lock bar 220 to move to the unlocked position (L3), so that the occupant can use the tongue (T) and buckle of the seat belt. It is possible to cancel the contract.

Specifically, the lock bar 220 is disposed in a through hole formed in the frame unit 100, that is, in the locking hole 110, and is moved in a direction perpendicular to the withdrawal direction of the tongue T by the magnetic force of the magnet 240. It can move toward the tongue (T), rise to a predetermined position, and move to the locking position (L2).

Here, the lock bar 220 moves toward the tongue (T) in a direction perpendicular to the withdrawal direction of the tongue (T), rises a predetermined position and moves to the locking position (L2), thereby attaching the tongue (T) to the frame unit 100. As long as this can be concluded, the structure, shape, and material may vary, and it is natural that the scope of the present invention is not limited due to this.

However, for more detailed explanation, as an example, the lock bar 220 may largely include an opposing surface 221, a stopping surface 222, and a raised surface 223, as shown in FIG. 4.

As shown in the drawing, the opposing surface 221 may be provided to contact or be spaced apart from the magnet 240 through the locking hole 110.

At this time, by making the length of the opposing surface 221 smaller than the diameter of the locking hole 110, interference between the lock bar 220 and the locking hole 110 can be prevented.

At this time, the engaging surface 222 may protrude in a direction toward the tongue T based on the above-mentioned opposing surface 221 and be coupled to the tongue T.

In other words, the lock bar 220 may have a locking surface 222 formed on the opposite side of the opposing surface 221, and the locking surface 222 may have a predetermined inclination based on the incoming and outgoing direction of the tongue T. It can be provided, and even if the engaging surface 222 is parallel to the incoming and outgoing direction of the tongue (T), that is, parallel to the opposing surface 221, it will all be said to fall within the scope of the present invention.

However, for more detailed explanation, as an example, the engaging surface 222 may be provided to have an upward or downward slope from one side to the other side, based on the opposing surface 221.

The raised surface 223 may be formed on the upper part of the above-described opposing surface 221 and may protrude to face the button 140 described above.

In other words, the raised surface 223 is formed on the upper side of the opposing surface 221 and can serve to move the lock bar 220 downward by receiving the pressing force of the buckle.

In addition, a first step 228 and a second step 229 may be formed on the lock bar 220 as shown in the drawing.

Therefore, one side of the tongue (T) is in contact with the first step 228 formed by the raised surface 223 and the engaging surface 222, and the other side is in contact with the second step formed by the engaging surface 222 and the opposing surface 221. It can be fixed to the lock bar 220 by contacting 229).

In other words, one side of the tongue (T) is in contact with the first step 228 of the lock bar 220, and the other side of the tongue (T) is in contact with the second step 229, thereby forming the tongue (T) into a frame unit ( 100) can be stably fixed without falling off.

With reference to FIGS. 5 to 8 , the position of the lock bar 220 according to the magnetic force of the magnet 240 will be described in detail as follows.

Referring to the drawing, the magnet 240 generates magnetic force in a first direction perpendicular to the withdrawal direction of the tongue (T), thereby attaching the lock bar 220 located at the unlocking position (L3) on one side of the locking hole (110) to the frame unit. It can be moved to the lockable position (L1) located on one side of the tongue (T) inserted into (100).

At this time, the lock bar 220 is raised by the ejector 120 provided at the lower part of the frame unit 100 to press the tongue T in the direction in which it is pulled out from the frame unit 100, and is moved to the lockable position L1 as described above. The tongue (T) can be fastened to the buckle by moving to the locking position (L2).

Here, when the passenger presses the button 140 provided on the upper part of the frame unit 100 in the locking position (L2) downward, the lock bar 220 is pressed downward by the button 140 and moves to the lockable position (L1). ) can be returned to.

However, if the vehicle is running at this time, even if the button 140 is pressed as described above, the magnetic force of the magnet 240 in the first direction is maintained, so the tongue T does not come off the buckle.

In other words, if the vehicle is running, no matter how much the passenger tries to release the tongue (T) and buckle, the fastening is maintained by magnetic force, thereby reducing the risk of serious injury and mortality due to seat belt release during driving. do.

Meanwhile, when the engine of the magnet 240 is turned off, the control unit (E) can cause the direction of magnetic force of the magnet 240 to be formed in a second direction opposite to the first direction.

Therefore, the magnet 240 returns the lock bar 220 from the lockable position (L1) to the unlocked position (L3), so that the tongue (T) of the seat belt and the buckle can be released when the operation is completed. It can be.

As described above, the buckle locking system using a magnet according to an embodiment of the present invention is designed to prevent the occupant from arbitrarily releasing the fastened seat belt while driving, thereby reducing the risk of injury and death to the occupant in the event of an accident. In particular, it is possible to prevent seat belt unfastening problems while driving, which can frequently occur in autonomous vehicles.

As described above, preferred embodiments according to the present invention have been examined, and the fact that the present invention can be embodied in other specific forms in addition to the embodiments described above without departing from the spirit or scope thereof is recognized by those skilled in the art. It is self-evident to them.
