Description

Parking assistance device {A PARKING ASSIST APPARATUS}

The present invention relates to a parking assist device, and more particularly, to a device in which the parking assisting jaw rises by pushing a bar placed on the parking surface with a wheel, and pushing the rod once again.

In recent years, inclined parking lots have been increasing to utilize the parking space more densely. Such a sloped parking lot has the advantage of utilizing space efficiently, but on the other hand, it is true that there is a greater risk of an accident due to slippage than when parking on a flat surface.

For this reason, people who use inclined parking lots may install the anti-skid jaws behind the wheels of the vehicle, but it is very cumbersome to install and remove the anti-skid jaw every time, so it is often reluctant to use it.

This invention makes it a subject to be able to prevent slipping on inclined parking surfaces. In addition, the object of the present invention is to be able to prevent slipping even without manually installing a non-slip jaw.

According to one aspect of the invention, the parking assist device,

A first bar disposed on the parking surface;

A push unit installed below the parking surface and connected to the first bar to move backward when the first bar moves forward;

A knock type member which is in contact with the push part and whose length is reduced or increased as the push part moves backward;

A second bar abutting the knock member and disposed parallel to the first bar; And

In contact with the second bar, the second bar protrudes on the parking surface during the forward movement, the second bar includes a non-slip jaw so as to be in parallel with the parking surface during the reverse movement.

Preferably,

The push part below the parking surface and the first bar on the parking surface are connected to each other with the parking surface interposed therebetween, so that the push unit moves backward when the first bar moves forward.

Preferably,

The knock member,

Outer cylinder with both ends drilled;

A pressing member installed at the first end of the outer cylinder and connected to the push unit;

A central body inserted into the outer cylinder;

1 is a view of the parking assisting apparatus according to the present invention from above, and FIGS. 2A and 2B are diagrams omitting a parking surface in order to explain the parking assisting apparatus according to the present invention in detail. Hereinafter, the present invention will be described in detail with reference to FIGS. 1 and 2A-2B. On the other hand, the components of the same reference numerals throughout the drawings of the present invention refers to the corresponding identical components.

First, the structure of the parking assistance apparatus of this invention is demonstrated.

The parking surface 1 is inclined, and in one embodiment, the inclined jaw 2 for making the inclination is disposed below the parking surface 1. Meanwhile, a first bar 3 is disposed on the parking surface 1, and a push part 4 connected to the first bar 3 is disposed below the parking surface. Next, a knock type member 5 is in contact with the push portion 4, and then a second bar 6 is in contact with the knock member 5 in parallel with the first bar 3. A pair of non-slip jaws 7 which are in contact with the two rods 6 are arranged. 2A and 2B, the parking surface embedding portion 4a of the pusher 4, the parking surface embedding portion 6a of the second bar, and the pair of non-slip jaws 7 are shown. The parking surface embedding portion 7a is embedded in the parking surface 1 with a play capable of minimum rotation, respectively.

Meanwhile, in the present invention, the term "knock type" is a term commonly used in a ballpoint pen. For example, when the pressing portion of the ballpoint pen is knocked, the ballpoint pen core is protruded, and when pressed again, the force is applied only in one direction as the ballpoint pen core is in the original position. Even if repeatedly applied, it means a method in which the components connected thereto repeat forward and backward (for example, Application No. 1020020077213 "Pencil Knock Writing Instruments", Application No. 1020087017460 "Knock Writing Instruments", Application No. 2019910002779 "Knocking Expression"). Writing instruments ", etc.). Therefore, in the present invention, the knocking member 5 responds to the pressing member 110 being repeatedly knocked by the pusher 4 so that the center body 130 of the knocking member 5 moves forward and backward. As you repeat, the length is reduced or increased repeatedly as a result. On the other hand, the operating principle of the knock-type member 5 will be described later with reference to FIG.

Hereinafter will be described the working principle of the present invention.

The driver can park from the floor to the parking surface (1). At this time, when the wheel of the vehicle pushes the first bar 3 forward and moves forward, the push part 4 connected to the first bar 3 moves backward. That is, as shown in FIG. 3, the push part 4 below the parking surface 1 and the first bar 3 above the parking surface are connected to each other with the parking surface 1 interposed therebetween, Is fixed to the parking surface by being buried in the parking surface with a clearance that allows a minimum rotation of the pair of parking surface filling portion 4a, thereby rotating the parking surface filling portion 4a about the axis. As a result, when the first bar 3 moves forward, the pusher 4 moves backward. Subsequently, as the pusher 4 moves backward, as the pressing member 110 (see FIG. 4) of the knock type member 5 connected thereto is pressed, as shown in FIG. 120, the length of the knock type member 5 is reduced as the central body 130 protruding outward returns to the inside of the outer cylinder 120 as shown in FIG. 2B, and the third elastic member 8 connected to the fixing surface 9 is reduced. The second rod 6 is moved forward by the elastic force of the anti-skid jaw 7 is thereby protruding. Subsequently, when the vehicle releases the wheel pressed backward, the pressing member 110 is returned to its original position in the pressed state by the elastic force of the first elastic member 140, and in response thereto, the push unit 4 is also returned.

Meanwhile, as shown in FIG. 2B, the driver slides the vehicle forward in the state where the non-slip jaw 7 protrudes above the parking surface, that is, the length of the knock type member 5 is reduced, thereby moving the first bar 3. When pressed, the pusher 4 moves backwards in response to this, and correspondingly, as the pressing member 110 of the knock type member 5 is pressed, the central body 130 moves outside the outer cylinder 120 as shown in FIG. 2A. By protruding, the length of the knock type member 5 is increased, and the second rod 6 connected to the knock type member 5 moves backward, and thus the non-slip jaw 7 is returned to its original position. At this time, when the vehicle releases the wheel pressed backward, the pressing member 110 is returned to its original position by being pressed by the elastic force of the first elastic member 140, and the push part 4 is also returned to the original position.

The detailed structure of the knock type member 5 is demonstrated with reference to FIG.

On the other hand, Figure 4 of the present invention shows an embodiment of the knock-type member 5, but this is only one example, even if the force is repeatedly applied in only one direction, the components connected to it to move forward and backward The member of the repetitive manner is applicable to the present invention as the knocking member 5 (for example, application No. 1020020077213 "Pencil knock writing instrument", Application No. 1020087017460 "Knocking instrument", Application No. 2019910002779 "Knocking type"). Writing instruments ", application 20-2003-0018235" knock writing instruments ", and the like.

The knock member 5 is installed on the outer cylinder 120, the first end 120a of the outer cylinder 120, which is open at both ends, and the pressing member 110 connected to the push unit 110, the central body inserted into the outer cylinder 120. 130, the first elastic member 140 installed between the coupling release unit 160 and the pressing member 110, the second elastic member 150 installed between the central body 130 and the second end portion 120b. , And an unlocking part 160 installed between the central body 130 and the first elastic member 140.

When the pressing member 110 is pressed, the rotating member 160a in contact with the pressing member 110 moves forward while the center body 130 overcomes the elastic force of the second elastic member 150 and moves forward, and the center body 130. Is exposed out of the second end 120b.

As described above, the rotating member 160a moves forward, and the upper end of the knock protrusion 160b is released from the guide groove 120c, and the vertex of the inclined surface 160e of the knock protrusion 160b is the guide protrusion 120d. When positioned below the vertex of the inclined surface (120e), the rotating member (160a) is rotated to engage the vertex of the inclined surface (160e) of the knock projection (160b) and the concave vertex of the teeth (160d).

When the force pressing the pressing member 110 by the push unit 4 in the above state is removed, the pressing member 110 is in the original position by the elastic force of the first elastic member 140, and the first 2, the center body 130 moves backward by the elastic force of the elastic member 150, and the inclined surface 160e of the knocking protrusion 160b is the inclined surface 120e of the guide protrusion 120d while the rotating member 160a moves backward. A predetermined angle rotates as it slides along), and the backward movement of the rotating member 160a stops as the knocking protrusion 160b is caught by the return preventing protrusion 120f.

When the pressing member 110 is pressed again in the above state, the rotating member 160a moves forward, and the knocking protrusion 160b is separated from the state in close contact with the return preventing protrusion 120f.

At this time, the rotating member (160a) is rotated again while the knock projection (160b) is over the guide projection (120d), so that the return preventing projection (120f) is located in the guide groove (120c) is not formed do.

When the pressing force of the pressing member 110 is removed by the pusher 4 in the above state, the pressing member 110 is returned to its original position by the elastic force of the first elastic member 140 and the second elastic member ( The central body 130 is moved backward by the elastic force of the 150, in turn the rotating member 160a is moved backward, the center body 130 is in a released state that is concealed into the outer cylinder (120).

As described above, as the pressing member 110 is repeatedly pressed, the fixed state and the released state are repeatedly made.

On the other hand, the structure of the second rod 6 and the non-slip jaw 7 is shown in detail in FIG.

As shown in FIG. 5, the non-slip jaw 7 includes a protrusion 7a, a force transmission portion 7b, and a parking surface embedding portion 7c (shown in FIG. 2) embedded in the parking surface. . To explain FIG. 5, for example, when the length of the knock type member 5 is reduced, the second rod 6 moves forward by the elastic force of the third elastic member 8 while the force transmission portion of the non-slip 7 is provided. (7b) is pushed forward, whereby the parking surface buried portion (7c) of the non-slip jaw (7) is buried in the parking surface, the non-slip jaw (7) rotates around the parking surface buried portion (7c) Thus, the protrusion 7a protrudes above the parking surface as shown in FIG. 2B.

By using the parking assist device of the present invention as described above, the non-slip jaw protrudes automatically by simply pressing the first bar 3 with the wheel during parking, and automatically pressing the first bar 3 with the front wheel again. The non-slip jaw is returned to its original position.

In the above, a preferred embodiment of the parking assisting apparatus according to the present invention has been described, but the present invention is not limited thereto, and various modifications can be made within the scope of the claims and the detailed description of the invention and the accompanying drawings. This also belongs to the scope of the present invention.
