Description

Technology Field

[0001] The present invention relates to an automatic umbrella device for vehicles, and more specifically, to an automatic umbrella device for vehicles configured on one side of the roof corresponding to the door of a large vehicle, which operates in conjunction with the door operation during rain to assist passengers in boarding and alighting from the vehicle. Background Technology

[0002] Generally, when passengers get on or off a vehicle in the rain, most of them use portable umbrellas. While this is not a problem when the rainfall is light, when the rain is heavy and the rain is thick, passengers are exposed to a lot of rainwater while folding or unfolding the umbrella during the short time it takes to get on or off, causing discomfort.

[0003] In addition, there are disadvantages such as rainwater frequently penetrating the interior of the cabin when the door is opened and boarding is performed after folding the umbrella, contaminating the interior of the cabin, causing the rainwater to enter the electrical components of the door and cause malfunctions, or corroding the body parts.

[0004] In particular, large vehicles such as buses carry a large number of passengers, so sliding doors tend to be left open for relatively longer periods compared to passenger cars. This is especially problematic for child protection vehicles, as the boarding and alighting times are even longer due to the presence of infants, resulting in the doors remaining open and being exposed to rainwater for extended periods.

[0005] Therefore, there has been a continuous demand to resolve the inconvenience of passengers boarding and alighting during rainy weather and to prevent rainwater from entering the vehicle cabin.

[0006] The matters described in this background technology section are written to enhance understanding of the background of the invention and may include matters that are not prior art already known to those skilled in the art to which this technology belongs. The problem to be solved

[0007] The present invention was developed in response to the requirements described above, and the problem that the present invention aims to solve is to provide an automatic umbrella device for vehicles configured on one side of the roof corresponding to the vehicle door, wherein, in the event of rain, a waterproof cloth is rolled up or unfolded in conjunction with the door operation in the manner of an awning to assist passengers in boarding and alighting from the vehicle without hindering the operation of the vehicle. means of solving the problem

[0008] In one or more embodiments of the present invention, a waterproof fabric housing is installed along the longitudinal direction of the vehicle body on the roof of the vehicle body corresponding to the door of the vehicle, having an opening along the longitudinal direction at the front, a roller groove formed along the longitudinal direction at the rear inner side, a waterproof fabric receiving portion formed along the longitudinal direction at the upper inner side, and a wire operating chamber formed along the longitudinal direction at the rear end; a waterproof fabric roller formed of a hollow tubular material, disposed along the longitudinal direction of the waterproof fabric housing inside the waterproof fabric receiving portion, and having both ends rotatably supported at both ends of the waterproof fabric housing; a waterproof fabric formed of a rectangular waterproof fabric, having its front end fitted and fixed to the waterproof fabric rim through the opening, and its rear end fitted to the waterproof fabric roller, which is wound or unwound by the waterproof fabric roller inside the waterproof fabric receiving portion; and waterproof fabric arms disposed at each end of the waterproof fabric housing, each front end hinge-connected to each end of the waterproof fabric rim, and having a bearing roller installed at each rear end so as to be movable along the roller groove. An automatic umbrella device for a vehicle may be provided, comprising: a drive motor installed through a motor case in the central part of the waterproof fabric housing, the rotation axis of which is fixed to a wire roller in the central part of the wire operating chamber; a wire installed such that each end is connected to the wire roller inside the wire operating chamber, and each other end is connected to a bearing roller installed at each rear end of the waterproof fabric arms on both sides, so as to be simultaneously wound or unwound on the wire roller according to the operation of the drive motor; a return spring disposed at both ends of the hollow part of the waterproof fabric roller, each outer end of which is fixed to a housing cover installed at both ends of the waterproof fabric housing, and each inner end is fixed to a spring pin installed to be movable along a pin groove in the longitudinal direction and fixed in the rotational direction inside the hollow part of the waterproof fabric roller, thereby providing a return rotational force to the waterproof fabric roller; and a control unit that detects the open / closed state of the door and controls the power supply to the drive motor using power from a battery.

[0009] The above waterproof fabric roller can be installed rotatably by being fitted into both ends of the waterproof fabric housing with bearings interposed at both ends.

[0010] The above waterproof fabric has fitting pins integrally formed at the front and rear ends, respectively, and can be installed by being inserted along the longitudinal direction into fitting holes formed in the waterproof fabric rim and the waterproof fabric roller, respectively, through the fitting pins.

[0011] The above waterproof fabric arm is rotatably installed at its rear end on a bearing pin, and the bearing pin can be installed to roll along the roller groove of the waterproof fabric housing by fitting bearing rollers at its upper and lower ends, respectively.

[0012] The above motor case can be assembled by a fitting method to the fitting ends formed on the upper and lower sides of the rear end of the waterproof fabric housing through fitting grooves formed on the upper and lower sides of the front end.

[0013] The above waterproof arm may be made of carbon composite material.

[0014] The above drive motor may be a stepper motor capable of controlling rotational speed and rotational direction.

[0053] FIG. 6 is a block diagram of a control unit applied to an automatic umbrella device according to an embodiment of the present invention.

[0054] Meanwhile, referring to FIG. 6, the control unit detects the open / closed state of the door (5) and controls the power supply to the drive motor (M) using the power from the battery (BT).

[0055] That is, the control unit includes a closed detection sensor (S1), an open detection sensor (S2), and a control board (CP).

[0056] A closing detection sensor (S1) is configured on one side of the door (5) to detect the closed state of the door (5) and output a detection signal, and an opening detection sensor (S2) is configured on the other side of the door (5) to detect the open state of the door (5) and output a detection signal.

[0057] The control board (CP) is configured inside the motor case (51) and controls the power supplied to the drive motor (M) in forward and reverse directions using the power of the battery (BT) according to the detection signals input from the closed detection sensor (S1) and the open detection sensor (S2).

[0058] FIG. 7 is a flat cross-sectional view of an automatic umbrella device according to an embodiment of the present invention with the waterproof fabric unfolded, FIG. 8 is a side cross-sectional view of an automatic umbrella device according to an embodiment of the present invention with the waterproof fabric unfolded, FIG. 9 is an enlarged view of part C of FIG. 6, FIG. 10 is an enlarged view of part D of FIG. 6, FIG. 11 is a flat cross-sectional view of an automatic umbrella device according to an embodiment of the present invention with the waterproof fabric unfolded, FIG. 12 is a perspective view of the state after operation of an automatic umbrella device according to an embodiment of the present invention applied to a bus vehicle.

[0059] Accordingly, an automatic umbrella device for vehicles having the configuration described above can be operated automatically when the main switch, which is configured separately, is in the ON state during rainy weather.

[0060] However, regarding the rotation direction of the drive motor (M), the direction of winding the waterproof cloth (31) onto the waterproof cloth roller (20) is defined as the forward direction, and the direction of unwinding the waterproof cloth (31) from the waterproof cloth roller (20) is defined as the reverse direction.

[0061] That is, as shown in FIG. 6, when the door (5) of the vehicle (3) is closed, the closing detection sensor (S1) outputs a detection signal to the control board (CP), and the control board (CP) supplies power to the drive motor (M) using the power of the battery (BT) to control reverse rotation.

[0062] Accordingly, the drive motor (M) rotates the wire roller (53) in the reverse direction, causing the wire (W) to unwind from the wire roller (53), and causes the waterproof fabric roller (20) to rotate in the reverse direction by the torsional elastic force of the return spring (RS), so that the waterproof fabric (31) is wound around the waterproof fabric roller (20).

[0063] Meanwhile, as shown in FIGS. 7 to 12, when the door of the vehicle (5) is open, the open detection sensor (S2) outputs a detection signal to the control board (CP), and the control board (55) supplies power to the drive motor (M) using the power of the battery (BT) to control forward rotation.

[0064] Accordingly, the drive motor (M) rotates the wire roller (53) in the forward direction to wind the wire (W) and spread out the waterproof cloth arm (33), thereby causing the waterproof cloth (31) to be unwound and spread out from the waterproof cloth roller (20).

[0065] At this time, the return spring (RS) forms a torsional elastic force as it rotates in the forward direction with the waterproof fabric roller (20) by the waterproof fabric (31) which is unfolded together with the waterproof fabric arm (33) by the rotational force of the drive motor (M), while each outer end of the spring (RS) is fixed to the housing cover (19).

[0066] In this way, the automatic umbrella device (1) for a vehicle according to an embodiment of the present invention, in conjunction with the operation of the (sliding) door (5) in the event of rain, the waterproof cloth (31) is automatically wound or unfolded onto the waterproof cloth roller (20) by the rotational force of the drive motor (M) and the torsional elastic force of the return spring (RS), thereby helping passengers board and disembark from the rain without hindering the operation of the vehicle.

[0067] In addition, when the user folds the umbrella and opens the door (5) to board, rainwater is prevented from penetrating into the interior of the vehicle, thereby preventing contamination of the interior of the vehicle. It is also possible to prevent rainwater from entering the electrical components for the door, thereby eliminating the cause of malfunction and preventing corrosion of the vehicle body parts.

[0068] In addition, as with vans, it can prevent the interior of the vehicle from being exposed to rainwater for a long time, even if there are many passengers or if the boarding and alighting time is longer due to infants.

[0069] Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment and includes all modifications within the scope recognized as equivalent that can be easily modified by a person skilled in the art to which the present invention belongs from the embodiment of the present invention.
