The blocking unit 110 is configured to switch between the reference mode and the standing mode according to the rotation state.

The reference mode includes a state in which the vehicle does not interfere with the progress of the vehicle and is fully accommodated in the mounting groove 120 and does not protrude or partially protrudes but does not obstruct the progress of the vehicle.

The standing mode is a state of blocking the progress of the vehicle and is a state in which at least a part protrudes from the installation groove 120 to block the vehicle from proceeding. At this time, the blocking unit 110 may protrude to a sufficient height in consideration of the shape of the vehicle so that the blocking unit 110 can contact the bumper of the vehicle or the like in the standing mode.

More specifically, in this embodiment, the blocking unit 110 has a rotation axis 112 formed at a predetermined center of a center, and has a first surface 113, a second surface 114, a third surface 115, And is formed so as to have four sides of the fourth surface 116.

The first surface 113 refers to a surface that is in contact with a vehicle that is traveling in the standing mode. That is, when the blocking unit 110 is in the stand-by mode, the first surface 113 faces the traveling vehicle, and when the blocking unit 110 is in the reference mode as shown in FIG. 2, Is directed downward.

In the present embodiment, the mounting groove 120 is formed with a protrusion 121, which includes a first corresponding surface 124 as a top surface and a second corresponding surface 122 as a side surface.

When the blocking unit 110 is in the reference mode, the upper surface of the first surface 113 is in contact with the first corresponding surface 124, and when the blocking unit 110 is in the standing mode, And the lower area of the first surface 114 is in contact with the second corresponding surface 122.

Accordingly, when the blocking unit 110 is switched to the standing mode, since the first surface 113 is supported by the second corresponding surface 122, even when a strong external force is applied, Can be blocked.

The second surface 114 refers to a surface formed on the opposite side of the first surface 113. [ That is, when the blocking unit 110 is in the stand-by mode, the second surface 114 is a surface located on the opposite side of the proceeding vehicle, and when the blocking unit 110 is in the reference mode, (113) faces upward.

The third surface 115 refers to a surface facing the upper side in the standing mode and the fourth surface 116 refers to a surface formed on the side opposite to the third surface 115.

At this time, at least one of the third surface 115 and the fourth surface 116 may be inclined so that the blocking unit 110 prevents the edge from interfering with the inner wall surface of the installation groove 120 Thereby enabling smooth rotation.

On the other hand, the control unit is a component that controls the driving of the blocking unit 110 according to a predetermined blocking condition. That is, the controller may switch the blocking unit 110 to the stand-by mode when a certain condition is satisfied.

At this time, the cutoff condition may include first and second conditions different from each other, which will be described later.

The fixed unit 130 is a component for fixing the blocking unit 130 in the reference mode. However, the fixed unit 130 may cancel the fixed state of the blocking unit 110 when the predetermined blocking condition is satisfied, and may be controlled by the control unit.

When the fixed state by the fixed unit 130 is released, the blocking unit 110 is switched to the standing state, which can also be controlled by the control unit. However, in addition to the method by the control unit, the blocking unit 110 may be formed to have a restoring force from the reference mode to the standing mode by a torsion spring or the like. In such a case, when the fixed state by the fixed unit 130 is released, it will be immediately restored to the stand-by mode.

The fixing unit 130 may be slidably inserted into the sliding groove 132 communicating with the side of the mounting groove 120 and may be inserted into the sliding groove 132. In this case, The blocking unit 110 can be released from the locked state.

It is needless to say that the fixed unit 130 may be implemented in various ways in addition to the form of the present embodiment.

As described above, the parking structure falling prevention device according to the first embodiment of the present invention has been described, and the control method according to the blocking condition will be described below.

As described above, the cutoff condition for switching the shutoff unit 110 to the stand-by mode includes the first condition and the second condition.

First, in the first condition, the first condition is a situation in which the door 10 is in a broken state.

That is, as shown in FIG. 3, when the vehicle V collides with the door 10 despite the fact that the door 10 is blocked due to sudden driving or a driving error, the control unit detects the breakage of the door 10 It can be determined that the first condition is satisfied.

This is to prevent an accident that the vehicle V pushes the door 10 and falls down while the elevator is not positioned on the floor.

In this case, the door sensor 140 may be provided to detect whether the door 10 is damaged. The door detection sensor 140 may be provided at various positions and may detect the breakage of the door 10 through various methods.

In particular, in the present embodiment, the door detection sensor 140 is installed at the rear bottom G of the door 10. When the door 10 is damaged, the door detection sensor 140 immediately recognizes that the door 10 is broken, and transmits the information to the controller. have.

Thereafter, the control unit releases the fixed state of the fixed unit 130 to switch the blocking unit 110 to the standing mode.

As described above, the present invention can effectively prevent a vehicle from falling down even in an unexpected situation such as breakage of the door 10 due to sudden driving or a driving error.

Next, referring to the second condition, the second condition refers to a situation where the condition that the door 10 is broken is satisfied.

That is, the control unit can switch the blocking unit 110 to the standing state, considering that an unexpected situation may occur at any time when the elevator is not positioned in the corresponding layer of the parking structure.

For this, the second embodiment of the present invention may include a position recognition sensor 30 provided in each floor of the parking structure as shown in FIG. 4 to detect whether or not the elevator 20 is positioned on the corresponding floor .

The position recognition sensor 30 may also be provided at various positions and may detect whether the elevator 20 is positioned in the corresponding layer through various methods.

Particularly, in the present embodiment, the position recognition sensor 30 is provided behind the stop position of the elevator 20, that is, on the inner wall surface of the parking structure. When the elevator 20 is recognized as not being positioned ahead of the elevator 20, the elevator 20 can transmit the corresponding information to the controller.

As described above, the present invention can be controlled so as to keep the blocking unit 110 operating at all times, so that a fall accident in an unexpected situation can be prevented in advance.

5 and 6 show an example of a driving process according to the satisfaction of the second condition. In Figures 5 and 6, a total of three layers of parking structures are shown, which are referred to as the first, second and third layers, respectively, from the bottom.

The first layer includes a first bottom portion G-1, a first blocking unit 110-1 including a first blocking unit 110-1, a first door 10-1, And a second fall prevention unit 100-2 including a second bottom portion G-2 and a second blocking unit 110-2 are provided in the second layer, 2, a second door 10-2 and a second position recognition sensor 30-2, and the third layer is provided with a third bottom G-3 and a third blocking unit A third door 10-3 and a third position detection sensor 30-3 are provided.

5, when the elevator 20 is positioned on the third floor, the elevator 20 is recognized by the third position sensor 30-3 provided on the third floor to be located on the third floor So that the third blocking unit 110-3 maintains the reference mode and the first blocking unit 110-1 and the second blocking unit 110-2 of the remaining layers are switched to the standing mode .

Therefore, the first layer and the second layer, in which the elevator 20 is not located, can prevent a falling accident in an unexpected situation in advance.

Next, as shown in FIG. 6, when the vehicle V enters the second floor to use the parking structure, the elevator 20 descends to the second floor and is located at the stop position.

In this state, the third position recognizing sensor 30-2 provided on the second layer recognizes that the elevator 20 is positioned on the second floor, Is switched to the reference mode for entry of the vehicle (V). And the third blocking unit 110-3 of the third layer is switched from the reference mode to the standing mode.

Therefore, the first layer and the third layer, in which the elevator 20 is not positioned, can prevent a falling accident in an unexpected situation in advance.

The blocking conditions of the present invention and examples according to the present invention have been described above. Hereinafter, a third embodiment of the present invention will be described.

7 is a detailed structural diagram of a parking structure fall prevention device according to a third embodiment of the present invention.

In the case of the third embodiment of the present invention shown in FIG. 7, all the components such as the blocking unit 100, the fixing unit 130, the mounting groove 120, and the like are formed in the same manner.

However, the present embodiment differs from the first embodiment in that the buffer portion 50 can be formed on at least one of the first corresponding surface 124 and the second corresponding surface 122 of the first surface 113. By forming the cushioning portion 50 in this way, the present invention can absorb the impact in each of the regions contacting each other.

Particularly, in the present embodiment, the buffer 50 is formed on the upper surface and the lower surface of the first surface 113 and on the second corresponding surface 122 on the basis of the standing mode.

Accordingly, the upper area of the first surface 113 can greatly alleviate the damage on the vehicle side in the event of a vehicle collision, and the lower area of the first surface 113 and the second corresponding surface 122 are in contact with each other The impact can be mitigated.

8 and 9 are views showing a structure of a parking structure fall prevention device according to a fourth embodiment of the present invention. In the case of the fourth embodiment of the present invention shown in Figs. 8 and 9, the structure of the fixed unit 230 is formed differently from the above-described embodiments.

In this embodiment, the fixed unit 230 includes a first link 232 and a second link 234, which are connected to each other by a link shaft 235 to be angularly adjustable with respect to each other. At this time, a rotation shaft 233 is formed at the center of the first link 232 to be rotatable.

At this time, the fixing unit 230 is accommodated in the receiving groove 126 formed in the bottom portion G, and the ends of the first link 232 and the second link 234 protrude outwardly .

The blocking unit 110 may include an insertion portion 118 into which the protruded end of the second link 234 is inserted so that the second link 234 is inserted into the insertion portion 118 The blocking unit 110 can maintain the reference mode.

In this state, when the vehicle enters and exerts an external force on the protrusion of the first link 232, the second link 234 is retracted by the rotation of the first link 232. Accordingly, the second link 234 is disengaged from the insertion portion 118, and the blocking unit 100 can be switched to the standing mode by the restoring force as shown in FIG.

In other words, in the case of this embodiment, since all the components have a mechanical driving system, there is an advantage that it is possible to operate safely even in an emergency such as a power failure.

On the other hand, all of the embodiments described above may be produced in a module form. That is, the blocking unit 110, the fixing units 130 and 230, and a frame in which the blocking units 110 and 230 are installed. In such a case, a groove may be formed in the bottom portion G of the parking structure, and then a fall prevention device of the module type can be provided.

It will be apparent to those skilled in the art that the present invention can be embodied in other specific forms without departing from the spirit or scope of the invention as defined in the appended claims. It is obvious to them. Therefore, the above-described embodiments are to be considered as illustrative rather than restrictive, and the present invention is not limited to the above description, but may be modified within the scope of the appended claims and equivalents thereof.
