Description

Headlight shield

[0001] The present invention relates to a headlight shielding device, and more particularly to a headlight shielding device that is installed on the windshield of a vehicle and can block the headlights of an oncoming vehicle.

[0002] Generally, on roads with four or more lanes, such as expressways and motorways, a median barrier is installed in the center of the road to separate the driving lanes of vehicles and ensure safety, and the median barrier is typically designed to have a certain height from the ground so as not to cause glare from the headlights of oncoming vehicles.

[0003] Due to these median barriers, drivers of small vehicles are protected from glare by blocking headlights regardless of the size of oncoming vehicles; however, drivers of large vehicles such as trucks and buses, whose driver's seats are positioned significantly higher than those of small vehicles, see the headlights of oncoming vehicles over the median barrier and thus do not receive the glare-prevention effect provided by the barrier.

[0004] Consequently, drivers operating large vehicles for extended periods at night accumulate fatigue due to glare from the headlights of oncoming vehicles, which is increasing the risk of accidents.

[0005] The present invention aims to solve the aforementioned problems by providing a headlight shielding tool that is installed on the windshield of a vehicle and can block the headlights of an oncoming vehicle from shining onto the upper side of the median strip.

[0006] The headlight shielding device of the present invention for achieving the above objective comprises: a shielding member formed in the shape of a plate having a predetermined length and width and including a shield capable of blocking light; and a support body configured to position the shielding member on the inner side of the windshield of a vehicle and to allow the shielding member to rotate around an axis crossing the shielding member.

[0007] Additionally, the above-mentioned shielding member further includes a rotating shaft that crosses the shielding and forms an integral part with the shielding, and the above-mentioned support body may include a first support body that is fixed inside the vehicle and is equipped with a first reduction gear motor to which one end of the rotating shaft is connected and which rotates the rotating shaft, and a second support body that is fixed inside the vehicle and is rotatably connected to the other end of the rotating shaft.

[0008] In addition, the second support body may include a tilting module that causes the other end of the rotation axis to tilt around one end of the rotation axis.

[0009] In addition, the connection between one end of the rotation shaft and the first drive shaft of the first reduction gear motor, and the connection between the other end of the rotation shaft and the second drive shaft of the tilting module, can be made through a connecting member formed of a soft elastic material that forms a tubular shape.

[0010] In addition, the above-mentioned rotating shaft has a fitting hole formed therein that allows a shield to pass through and be forcibly fitted between one end and the other end, so that the area of ​​the shield portion protruding upward and the shield portion protruding downward can be adjusted as the position where the rotating shaft crosses the shield is changed.

[0011] According to the present invention, when a shielding member is installed adjacent to and parallel to the top of a median strip visible through the windshield of a vehicle, the headlights of a vehicle approaching from beyond the median strip are blocked by the shielding member, thereby preventing glare caused by the headlights and significantly reducing fatigue and the risk of accidents.

[0012] In addition, the shielding member can be rotated on an axis according to road conditions or the driver's needs to adjust the area and angle of light blocking, and since the control of this shielding member can be performed wirelessly, convenience of operation can be ensured without any special restrictions on driving the vehicle.

[0021] The present invention proposes a headlight shielding tool comprising: a shielding member formed in the shape of a plate having a predetermined length and width and capable of blocking light, so as to be installed on the windshield of a vehicle to block the light from the headlights of an oncoming vehicle even if the light shines onto the upper side of the median strip; and a support body that positions the shielding member on the inner side of the windshield of the vehicle and allows the shielding member to rotate around an axis crossing the shielding member; wherein the shielding member can be positioned adjacent to and parallel to the upper side of the median strip visible through the windshield of the vehicle, and can adjust the area and angle of light blocking by rotating around the axis.

[0022] The scope of the present invention is not limited to the embodiments described below, and various modifications may be made by those skilled in the art within the scope of the technical essence of the present invention.

[0023] Hereinafter, the headlight light blocking tool of the present invention will be described in detail with reference to the attached FIGS. 1 to 9.

[0024]

[0025] The headlight shielding tool of the present invention is configured to block the headlights of a vehicle approaching from the opposite lane by including a shielding member (100) capable of blocking headlights shining toward a driver as shown in FIGS. 1 to 3, and a support body (200) that positions the shielding member (100) on the inner side of the windshield of the vehicle.

[0026] The shielding member (100) includes a shield (110) formed in the shape of a plate having a predetermined length and width and capable of blocking light, and as an example, the shield (110) may be composed of a thin blackout film forming a rectangular plate shape.

[0027] The shield member (100) is rotated by the support body (200) around an axis that crosses the shield member (100), and may further include a rotation axis (120) that is integral with the shield (110) and rotatably coupled to the support body (200), as shown in FIG. 3. The rotation axis (120) is formed in the shape of a rod having a length longer than the length of the shield (110), so that it crosses the shield (110) and becomes integral with the shield (110), with both ends protruding from one end and the other end of the shield (110), respectively. Accordingly, when the rotation axis (120) is rotated by the support body (200), the shield (110) rotates around the rotation axis (120).

[0028] This rotating shaft (120) may be provided to pass through the interior of the shield (110), as well as to pass through the exterior of the shield (110). Additionally, the rotating shaft (120) may be configured so that the shield (110) can be forcibly fitted and fixed. For example, as shown in FIG. 4, the rotating shaft (120) may have a fitting hole formed between one end and the other end through which the shield (110) can pass and be forcibly fitted. Accordingly, as shown in FIG. 5, the user can change the position where the rotating shaft (120) crosses the shield (110), thereby adjusting the area of ​​the shield (110) portion protruding upward from the rotating shaft (120) and the shield (110) portion protruding downward from the rotating shaft (120). That is, the area where light is blocked by the shield (110) on the upper and lower sides around the rotation axis (120) can be easily changed.

[0029] As previously described, the support body (200) allows the shielding member (100) to be positioned on the inner side of the vehicle's windshield and allows the shielding member (100) to rotate around an axis that crosses the shielding member (100).

[0030] This support body (200) may include a first support body (200a) provided on one side of the shield (110) and a second support body (200b) provided on the other side of the shield (110) so as to support both ends of a rotating shaft (120) that is integral with the shield (110).

[0031] For example, the first support body (200a) and the second support body (200b) may be formed in the shape of a hollow container, and it is preferable that they be formed to have a height greater than the width of the shield (110) so that the shield (110) does not come into contact with the windshield when the shield (110) rotates on its axis. In addition, the first support body (200a) and the second support body (200b) may be provided with a fixing means on their bottom surfaces for fixing them inside the vehicle, such as the windshield of the vehicle or the inner body near the windshield of the vehicle. The fixing means may be, for example, a suction cup that can be easily attached and detached as shown in FIGS. 2 and 3, or it may be a tape that can be firmly fixed.

[0032] Specifically, the first support body (200a) may be equipped with, as shown in FIG. 3, a first reduction motor (210) to which one end of the rotation shaft (120) is connected and which rotates the rotation shaft (120), a first battery for supplying power to the first reduction motor (210), and a first control module for controlling the operation of the first reduction motor (210).

[0033] The first reduction motor (210) includes a first drive shaft (211) connected to the rotation shaft (120) to transmit driving force to the rotation shaft (120), and the first drive shaft (211) may be provided to protrude outward by penetrating the side of the first support body (200a). At this time, one end of the rotation shaft (120) and the first drive shaft (211) of the first reduction motor (210) may be interconnected through a connecting member (130), and the one end of the rotation shaft (120) and the first drive shaft (211) are press-fitted into the connecting member (130), so that when the first reduction motor (210) operates and the first drive shaft (211) rotates, driving force can be transmitted to the rotation shaft (120).

[0034] The connecting member (130) connecting one end of the rotating shaft (120) and the first drive shaft (211) of the first reduction motor (210) may be made of a hard material in a tubular shape, but it is preferable that it be formed of a soft elastic material in a tubular shape so that the driving force can be easily transmitted even if vibrations occur during vehicle operation or tilting of the rotating shaft (120) by the tilting module (220) described later occurs.

[0035] The first control module, although not shown in the drawing, can operate the first reduction motor (210) according to a control signal, and the control signal may be generated by operating a remote control held by the user or a button provided in the vehicle.

[0036] The other end of the rotation shaft (120) can be rotatably connected to the second support body (200b). At this time, the other end of the rotation shaft (120) can be rotatably connected while directly penetrating the second support body (200b), and a support drive shaft can be provided on the second support body (200b) so as to be rotatably connected toward the other end of the rotation shaft (120), and the support drive shaft and the other end of the rotation shaft (120) can be connected through the aforementioned connecting member (130).

[0037] And the second support body (200b) may be equipped with a tilting module (220) that causes the other end of the rotation axis (120) to tilt around one end of the rotation axis (120), a second battery for supplying power to the tilting module (220), and a second control module for controlling the operation of the tilting module (220).

[0038] The tilting module (220) may include, as illustrated in FIGS. 6 and 7, a reciprocating shaft (221) having both ends rotatably arranged along the width direction of the second support body (200b) and a spiral-shaped moving guide groove formed along the length direction on the outer surface, a second reduction motor providing a driving force to rotate the reciprocating shaft (221) around a longitudinal axis, a moving pin protruding toward the moving guide groove and capable of moving along the moving guide groove, a moving piece (222) that moves along the length direction of the reciprocating shaft (221) according to the rotation of the reciprocating shaft (221), and a second driving shaft (223) which is a supporting driving shaft formed from the moving piece (222) toward the other end of the rotation axis (120), penetrating the second support body (200b), and connected to the other end of the rotation axis (120).

[0039] In this tilting module (220), when the reciprocating shaft (221) rotates by receiving driving force from the second reduction motor, the moving member (222) moves in one direction, and the second drive shaft (223) also moves together with the moving member (222), so that the other end of the rotation shaft (120) connected to the second drive shaft (223) can be tilted around one end of the rotation shaft (120). For example, when the first support body (200a) and the second support body (200b) are fixed to the windshield of a vehicle as shown in FIG. 8 through fixing means provided on each bottom surface, as shown in FIG. 9, when the reciprocating shaft (221) is rotated counterclockwise, the other end of the rotation shaft (120) can be moved upward, and when the reciprocating shaft (221) is rotated clockwise, the other end of the rotation shaft (120) can be moved downward.

[0040] And, the second drive shaft (223) is preferably connected to the other end of the rotation shaft (120) through a connecting member (130) formed of a soft elastic material in a tubular shape so that it can be easily rotated even when the rotation shaft (120) is tilted, and the other end of the rotation shaft (120) connected to the second drive shaft (223) through the connecting member (130) is preferably coupled with the connecting member (130) so that it can rotate independently.

[0041] Additionally, the second control module, although not shown in the drawing, can operate the second reduction gear motor according to a control signal, and the control signal may be generated by operating a remote control held by the user or a button provided in the vehicle.

[0042] When examining an example of blocking the headlights of a vehicle approaching from the opposite lane beyond the median strip (10) using the headlight shielding tool of the present invention as described above, when the first movable body (200a) and the second movable body (200b) constituting the support body (200) are fixed inside the vehicle, if the shielding member (100) is positioned adjacent to and parallel to the top of the median strip (10) visible through the vehicle's windshield, the headlights of the vehicle approaching from beyond the median strip (10) are blocked by the shielding member (100), so the driver can prevent glare caused by the headlights of the oncoming vehicle.

[0043] In addition, the shield member (100) can be rotated on an axis according to road conditions or the driver's needs to adjust the area and angle of light blocking, and the control of the shield member (100) can be done wirelessly, so the operation of the shield member (100) can be easily controlled without any special restrictions on driving the vehicle.
