Description

Smart apparatus for preventing overspeed {Smart apparatus for preventing overspeed}

The present invention relates to a speeding prevention device, and more particularly, to a smart speeding prevention device.

In general, a speed bump is mainly installed as a device for preventing speeding. These speed bumps are installed in school zones around schools, around residential areas, or on roads where many people pass, and are mainly installed for the purpose of preventing speeding driving of passing vehicles.

In addition to the purpose of limiting the speeding of vehicles in terms of functionality, these speed bumps are also required for additional functions such as reducing traffic volume, securing pedestrian space, improving road scenery, and suppressing on-street parking.

On the other hand, these speed bumps are installed to induce the driver to lower the speed by forming a hill of a certain height perpendicular to the direction in which the vehicle travels.

However, in the conventional speed bump, the driver recognizes that the speed bump is installed while driving, and even if the speed of the vehicle is lowered, the moment the vehicle passes through the speed bump, the impact force transmitted to the vehicle is completely transmitted to the vehicle and the driver, and the vehicle shakes severely However, it can become a risk factor that hinders the driver's safe driving.

In addition, in the conventional speed bump, installation standards for speed bumps are presented according to the road width as shown in (a) of FIG. 1, but in actual installation, these installation standards are often not followed.

For example, when a speed bump is installed higher than the installation standard, a large impact may be applied to the vehicle body when the vehicle passes as shown in (b) of FIG. 1 . In particular, when a vehicle with a low height passes through such a speed bump, there is a problem in that the lower body of the vehicle is physically damaged. In addition, the surface of the speed bump is also damaged, which may be a factor that impairs the aesthetics of the road.

<First Embodiment>

Referring to FIG. 2 , the smart overspeed prevention device according to the first embodiment of the present invention is composed of a cover part 10 and a body part 20.

The cover part 10 is installed to be able to turn at a predetermined angle from the top of the main body part 20 with the turning part 50 as a starting point. In addition, the pivoting unit 50 may be connected to the main body 20 through the first pivoting shaft 50a and the second pivoting shaft 50b.

On the other hand, inside the body portion 20, a drainage portion 30 is formed on the bottom for drainage when buried in the ground. In addition, a driving roller unit 40 is installed to operate the cover unit 10 on the body unit 20 . The driving roller unit 40 includes a first support roller 40a and a second support roller 40b provided inside the body portion 20 .

Referring to FIG. 3 , a cylinder 41 of the main body 20 is connected to a connection plate 45 and a roller 47 may be rotated through a roller plate 46 . At this time, a cylinder connection block 42 is installed on the inner wall of the main body 20, one end of the cylinder 41 is connected, and a rod 42 is mounted on the other end of the cylinder 41, and the rod 42 is connected. Plate 45 is connected. Accordingly, the rod 42 of the cylinder 41 is moved in a linear direction in the cylinder 41, and the connection plate 45 can be turned at a constant radius as shown in FIG. 3.

Meanwhile, a roller plate 45 is connected to the connecting plate 45, and a roller 47 is mounted on the roller plate 45. Here, the roller plate 46 is pivotally mounted by the front support block 44 mounted inside the body portion 20, and when the connecting plate 45 is driven by the operation of the cylinder 41, the roller plate ( 46) also pivots on the front support block 44. As a result, the roller 47 connected to the front end of the roller plate 46 can be turned at a predetermined radius while supporting the lower surface of the cover 11 by driving the cylinder 41 .

Therefore, when the cylinder 41 is driven, the linear motion of the rod 43 is converted into the pivoting motion of the connecting plate 45, and the pivoting motion of the roller plate 46 connected therewith turns the roller 47 at a certain radius. . Accordingly, the cover 11 supported by the rollers 47 can be switched from the same state as the collision part 21 to a downward biased state.

Here, it is preferable that a part of the surface of the roller 47 be made of an elastic material to reduce the occurrence of frictional noise or abrasion of the cover 11 .

On the other hand, the collision part 21 is provided in the form of an attached bent piece bent outward from the side wall of the body part 20, as shown in (b) of FIG. Of course, it may be formed by bending a part of the upper end of the side wall outward without attaching a separate bending piece. Here, the degree of bending is preferably provided in a gentle round shape with a certain curvature so as not to cause damage when a vehicle wheel passes.

In addition, when the cover 11 is located on the same line as the collision part 12 (that is, the state of the device when the vehicle is traveling at a constant speed), the cylinder 41 can be maintained so that the roller plate 46 can be maintained in a vertically erected state. The front end of the is inclined downward at a certain angle.

On the other hand, when the cover 11 descends approximately 5 to 7 cm from the impact part 12 (that is, when the vehicle is traveling at high speed), the roller plate 56 is tilted outward at a certain angle, and at this time, the roller 47 ) remains supported on the inner wall of the body portion 20 while the cylinder 41 takes a posture parallel to the ground to maintain this state.

Here, a rear support block 22 is installed inside the body portion 20, and a cover 11 is pivotably installed on the top of the rear support block 22 via a pivot shaft 50a.

<Second Embodiment>

Referring to FIGS. 4 and 5 , in the smart overspeed prevention device according to the second embodiment, the cover 61 is installed on the upper surface of the main body 51 so as to be able to turn around the pivot 62 as a starting point. In addition, at the end of the cover 61, an inlet end 63 having an inclined surface is formed, and a closing end 51a is formed in the main body 51 so as to be close to the inlet end 63. Accordingly, the inclined surface of the inlet end 63 is positioned on the same line as the closing end 51a as shown in FIG. 5 so that the end of the inlet end 63 does not protrude outside when the cover 61 is lowered.

Next, the pivot shaft 62 is installed on the rear support block 54 installed inside the main body 51. In addition, on the lower surface of the cover 61, the roller 71 is supported by the pivoting shaft 73 by the connection plate 74. In addition, a drainage part 80 for natural drainage is formed on the bottom surface of the main body 51 .

Meanwhile, a stopper member 55 is formed on the inner wall of the main body 51 . This stopper member 55 functions to support the roller 71 in a state where the cover 61 is lowered on the main body 51 . That is, when the vehicle speeds up, the cover 61 functions to limit the further descent of the roller 71 in a state in which the cover 61 is descended by a certain width (5 to 7 cm) into the body 51. For example, it serves to prevent the cover 61 from sinking due to the weight of the vehicle.

In addition, a height adjusting unit 52 for adjusting the installation position or leveling of the body 51 during installation is installed at the lower part of the body 51 . Referring to FIG. 5 , a plurality of LEDs are installed on the exposed surface of the collision part 53 (when the vehicle is speeding) to warn the driver.

Referring to FIG. 6 , (a) of FIG. 6 shows an internal state of the smart speed prevention device when a vehicle passes at a constant speed. That is, the cylinder 91 is maintained so that the connection plate 74 is vertically erected with respect to the cover 61 .

Figure 6 (b) shows the internal state of the smart speed prevention device when the vehicle passes at speed. That is, in a state in which the rod 92 of the cylinder 91 is drawn in and the roller 71 is moved clockwise by a predetermined angle, the front end of the cover 61 descends into the inside of the main body 51 on the roller 71 achieve a state In this state, the collision portion 53 is exposed, and the vehicle collides with the collision portion 53 to provide a rattle to the driver, thereby allowing the driver to recognize speeding. Here, a stopper 55 is mounted on the inner wall of the main body 51 to support the roller 71 in an inclined state, thereby preventing the cover 61 from sinking more than the set width due to the weight of the vehicle when the vehicle passes.

That is, when the cover 61 is more depressed than the set width (for example, 5 to 7 cm) by the weight of the vehicle, a greater rattle can be provided to the driver, and in some cases, the collision part 53 Since the impact area of ) becomes deep and can lead to damage to the vehicle, a stopper 55 is installed as a support element to solve this problem.

As shown in FIG. 7, the smart speeding prevention device of the present invention configured as described above detects the speed of a passing vehicle through the speed sensor of the radar measurement method, and detects 'overspeed' faster than the reference speed, and detects the driving roller unit within about 1 second. It is driven to convert the cover from the main body to a state in which it is lowered to a certain width (for example, 6 cm or less).

Accordingly, the driving vehicle's wheels collide with the impact portion 53 (FIG. 6) exposed by the lowering of the cover, and the driver feels the vehicle's rattle, thereby recognizing speeding. Of course, when the speed detector detects 'constant speed', the cover maintains its position on the same line as the ground, enabling smooth driving.

As described above, according to the present invention, as a method buried in the ground, it is possible to induce deceleration of the vehicle while ensuring the safety of the driver as well as the aesthetics of the road by replacing the existing speed bump installed in the form of a hill on the road.

In addition, the present invention operates only when the vehicle is speeding, so that smooth traffic flow can be secured within the prescribed speed.

In addition, since no physical impact is applied to the driver when the vehicle passes within the prescribed speed, it is possible to induce a habituation (nudge effect) for constant speed driving through such compensation psychology.

In the above, the present invention has been shown and described with respect to specific embodiments, but the present invention is not limited only to the above-described embodiments, and those skilled in the art to which the present invention belongs will find the present invention described in the claims below.
