Description

Parking lot passage accident prevention system and its learning mode setting method {Parking lot passage accident prevention system and its learning mode setting method}

In the case of an underground parking lot or parking building having multiple floors, the present invention is characterized in that most of the passages moving between floors are narrow, steep, and curved. Therefore, in the inter-floor passageway, there are many blind spots where the driver cannot directly check the degree of interference between the vehicle and obstacles (walls, boundary stones, pillars, etc.) with the naked eye or rearview mirror. Contact accidents or contact accidents with vehicles in the opposite direction occur frequently. The present invention is intended to solve such a problem.

As shown in FIG. 6 , it consists of a lower bracket 10 , an upper bracket 20 , a bearing 30 , a steel round bar 40 , a tension spring 50 , and a buffer pipe 60 .

The lower bracket 10 is smoothly pivoted to a predetermined height such that the tension spring 50 and the buffer pipe 60, which will be described later, are rotatable on the floor of the parking lot, that is, to a height that can contact the wall from the sea side of the vehicle. It is formed to minimize damage, and is formed in a plate body and a plurality of bolt holes 12 are formed through one side to be coupled to the anchor bolt formed on the floor of the parking lot. And, the lower bearing coupling hole 104 is formed on the other side on the same plane as the bolt hole 12, and is horizontally installed on the floor of the parking lot.

Here, the tension spring 50 and the buffer pipe 60, which will be described later, from the parking lot floor by the thickness of the lower bracket 10 can be positionally coupled to each other, so that when turning due to an external shock, the vehicle turns smoothly without interference from the floor. will become

The upper bracket 20 is positioned upward on the same vertical line as the lower bracket 10 described above, and a vertical piece 21 having a plurality of bolt holes 212 formed thereon to be coupled to the anchor bolt formed on the wall of the parking lot is provided. and an upper bearing coupling hole 22 formed to face upward on the same vertical line as the lower bearing coupling hole 14 of the lower bracket 10 on one surface of the end side that is bent orthogonally to the vertical piece 21 and extended integrally -2) is formed with the formed horizontal piece 220 .

Here, the upper bracket 20 is formed in a “L” shape in which the vertical piece 21 and the horizontal piece 22 are integrally bent.

That is, the lower bracket 10 and the upper bracket 20 are positioned vertically on the same vertical line, and the tension spring 50 and the buffer pipe 60 to be described later are positioned on the same vertical line with the lower bracket 10 and the upper bracket ( 20) The upper and lower brackets are installed at intervals of a certain height to be coupled between them.

Here, the interval at which the upper and lower brackets are installed is preferably formed to have a height corresponding to the height of the bumper of the vehicle or the height of a specific part of the vehicle that is easily in contact with the wall surface.

The bearing 30 is formed such that a tension spring 50 and a buffer pipe 60, which will be described later, rotate by an external impact, and is fixedly coupled to the above-described upper and lower bearing coupling holes 22-2 and 14, respectively, to move up and down. arranged to face each other.

The steel round bar 40 is to rotatably couple both ends of a tension spring to be described later with the bearing 30 , and are vertically opposed to each other to face each other and are respectively fitted to the inner rings of the bearings 30 . composed in the form

Here, it is preferable that a through hole or a fitting groove (not shown) is formed on the outer periphery of the steel round bar 40 to facilitate end coupling of the tension spring to be described later.

The tension spring 50 is formed long in the vertical longitudinal direction between the upper and lower brackets 20 and 10, and the upper and lower ends are respectively coupled to the steel round rods 40 fitted to the inner rings of the upper and lower bearings 30. It is rotatable, and it is elastically deformed horizontally by an external shock on the horizontal plane and is provided to be restored again. Here, the tension spring 50 is preferably formed of a coil spring.

That is, when an impact from the outside is applied to the side, the tension spring 50 is elastically deformed in the opposite direction to which the impact is applied, and the direction of the applied external impact is turned and rotates. Thereafter, the tension spring 50 as a whole returns to its original state before the shock is applied again by the elastic force along with rotation, thereby guiding the traveling direction of the vehicle while buffering it without damaging the bumper of the vehicle. But. At this time, the tension spring 50 has metallic properties, so it can damage the painted surface of the vehicle, such as scratches. It is provided so that scratches do not occur on the vehicle surface.

As mentioned briefly above, the buffer pipe 60 is coupled to the outer periphery of the tension spring 50 to prevent scratches such as scratches caused by the tension spring 50 on the painted surface of the vehicle, and the first vehicle comes into contact with it. At the time, it acts as a buffer and interacts with the tension spring 50 so that the driver can correct the direction of the vehicle. It is formed of EVA (Ethylene.Vinyl.Acetat) to initially buffer external shocks.

However, it is impossible to prevent a contact accident in advance with the background technology as described above.

As the technology that is the background of another invention, the vehicle cannot be made entirely of transparent material, so it is inevitable to create a blind spot that the driver cannot see by obscuring the driver's view.

In contrast, the parking lot is an auxiliary facility, and in order to maximize the number of parking spaces compared to the building area, a lot of the driver's view is blocked by the building pillars or walls, there are sharp curves and steep slopes in the passages moving between floors, and the driving lines are connected rapidly. It is characterized by a high risk of accidents as there are many parts.

The driver drives while checking the front and rear and sides of the vehicle through the side-mirror, room-mirror, and transparent glass in the vehicle, but since the entire vehicle cannot be made of transparent material, it is inevitably a blind spot that the driver cannot see directly. occurs

In particular, there are many blind spots that the driver cannot see around the front wheel of the vehicle, the lower right side of the vehicle, and around the front and rear bumpers.

In a multi-storey parking lot, such as a parking building or underground parking lot, curves and slopes occur at the same time in the curved passageway that connects the floors. A lot of accidents happen with

Currently, the following technologies have been developed and used to prevent vehicle contact accidents in parking lots.

First, since the number of blind spots increases, a fixed reflector is installed at a point where there is a high risk of an accident to reduce the driver's blind spot, thereby supporting safe driving.

The road reflector, which is installed at a point where there is a high risk of accidents due to the occurrence of blind spots, reduces the occurrence of blind spots for drivers. It consists of a fixing pole.

From the driver's point of view, the position of the reflector and the direction of the convex mirror are determined and installed so that the blind spot for the area with high risk of accidents is minimized.

Second, the risk of contact accidents is reduced by adding a convex lens to the rearview mirror or attaching a separate rearview mirror to the vehicle to reduce blind spots.

Third, when the passage between floors in the parking lot is narrow, a rotating parking guard rail (Patent Registration No. 10-1302709) is installed and operated on the parking lot wall in rare cases to prevent vehicle damage due to contact between the wall and the vehicle.

However, although conventional technologies are applied for parking lot operation, the following problems occur.

First, in the case of a fixed reflector, the driver's view only partially enlarges at the point where the reflector is installed (eg, at the entrance to the parking lot, etc.), but does not expand the driving view for the entire curved passageway connecting the floors.

Second, if a separate convex lens is added to the vehicle, the driver's blind spot is partially reduced, but the effect is very limited in the blind spot that occurs close to the vehicle, such as a parking lot.

Third, installing the rotating parking guard rail on the wall is only to reduce damage when a contact accident occurs between the vehicle and the wall, not to prevent the accident itself, so the effect is very limited.

The present invention was devised for accident prevention under such a background.

In the case of a multi-story underground parking lot or parking building, most of the passages between floors are narrow, steep, and curved.

Therefore, in the inter-floor passageway, there are many blind spots where the driver cannot directly check whether a vehicle and obstacles (walls, boundary stones, pillars, etc.) can collide with the naked eye or rearview mirror. In this case, contact accidents with obstacles or contact accidents with vehicles in the opposite direction occur frequently.

In addition, in a multi-storey parking lot, the point where the passage moving between floors and the passage moving within the floor meet has a sharp change in inclination and is connected almost at right angles without a winding curve. If you do not slow down when driving on the inter-floor passageway, there is a high risk of contact accidents between vehicles or between vehicles and obstacles.

In order to solve these problems, in the present invention, when the vehicle travels on the inter-floor movement path, the driver directly checks the free space between the wall of the movement passage and the side of the vehicle while driving safely along the movement passage wall at the same speed as the vehicle. Invented a technology for moving the moving mirror. In addition, in this technology, by limiting the moving speed of the moving mirror to a safe speed or lower, the vehicle speed in the inter-floor passage is limited, thereby reducing the risk of an accident.

The present invention provides a rail installed at a constant height along the wall of the inter-floor movement path, and a moving mirror unit (robot) that moves along the rail while maintaining a constant distance from the vehicle traveling in the movement passage. It consists of a convex-lens rearview mirror that allows the driver to see clearly, a detector that detects the distance between the vehicle and the mirror in real time, and an actuator that moves the moving mirror (robot) to maintain a constant distance from the vehicle.

The moving mirror unit is coupled to the reciprocating unit, and eventually, the coupled moving mirror unit moves by moving the reciprocating unit.

Among the components of the reciprocating part shown in Fig. 3, it is used to change the rotational motion into a linear motion or vice versa by the engagement of the rack and the pinion.

The rack (rack) is arranged in a straight line and the pinion (pinion) is configured to rotate on top of the rack.
