Technology Field

[0001] The present invention relates to a detachable emergency warning sign for preventing traffic accidents, and more specifically, discloses a technology for preventing traffic accidents by attaching it to the trunk of a vehicle or by having the driver carry and use it when necessary. Background Technology

[0002] In the event of a traffic accident or breakdown, personal injury caused by rear-end collisions frequently occurs as drivers exit their vehicles to handle the situation. This is particularly problematic at night, as reduced visibility often prevents drivers from spotting pedestrians on the road, which is being pointed out as a significant social issue. To address this problem, technologies have been developed to expose emergency signs using the vehicle's trunk. However, most of these technologies require the driver to exit the vehicle and perform operations, such as installing a separate sign, which limits their ability to fundamentally prevent accidents.

[0003] Among the prior art, Korean Registered Patent No. 10-1923651 (published on November 30, 2018) relates to an emergency warning sign for attachment to a vehicle trunk. By attaching it to the trunk lid of a vehicle so that when the trunk lid is opened, a warning lamp module can simultaneously provide a warning indication to the rear, thereby allowing the driver to provide an emergency warning indication to a rear vehicle even if they only operate the trunk opening operation without getting out of the vehicle. Furthermore, by flashing an LED lamp in addition to a simple reflective sheet, the identification performance for rear vehicles can be further improved, thereby preventing the risk of safety accidents caused by the driver getting out of the vehicle in emergency situations, as well as preventing secondary accidents by further strengthening the emergency warning indication.

[0004] However, the above conventional technology had a limitation in that the warning sign had to be used only on the vehicle, so there was a risk of a secondary accident when the driver moved outside the vehicle. The problem to be solved

[0005] The technical problem to be solved by the present invention is to provide a detachable emergency warning sign for preventing traffic accidents that can be attached to a vehicle or detached and carried by a user to prevent secondary accidents.

[0006] In addition, the purpose is to provide a detachable emergency warning sign for preventing traffic accidents that can prevent rear-end collisions by outputting lighting signals, such as symbols, characters, and shapes, through the lights in response to the driving signals of the vehicle's brake lights, turn signals, and hazard lights.

[0007] In addition, the purpose is to provide a detachable emergency warning sign for preventing traffic accidents that can output a warning signal through an alarm and transmit the warning signal to an external user terminal.

[0008] In addition, the purpose is to provide a detachable emergency warning sign for preventing traffic accidents that can output warning signals, such as symbols and characters, onto the road surface using a laser signal.

[0009] In addition, the purpose is to provide a detachable emergency warning sign for preventing traffic accidents that can adjust the angle of the laser signal according to the opening height of the trunk. means of solving the problem

Specific details for implementing the invention

[0019] Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings. The terms used are selected considering their functions in the embodiments, and their meanings may vary depending on the intent of the user or operator, or case law. Therefore, the meaning of the terms used in the embodiments described below shall follow the definitions specifically defined in this specification if such definitions exist, and shall be interpreted according to the meaning generally recognized by those skilled in the art if no specific definitions exist.

[0021] FIG. 1 is an example of use of a detachable emergency warning sign for preventing traffic accidents according to an embodiment of the present invention, FIG. 2 is a configuration diagram of a detachable emergency warning sign for preventing traffic accidents according to an embodiment of the present invention, FIG. 3 and FIG. 4 are example diagrams for explaining that the detachable emergency warning sign for preventing traffic accidents according to FIG. 2 unfolds in an X shape, FIG. 5 is an example diagram for explaining that the body part of the detachable emergency warning sign for preventing traffic accidents according to FIG. 2 is coupled to an emergency vest, and FIG. 6 is an example diagram for explaining that the detachable emergency warning sign for preventing traffic accidents according to FIG. 2 outputs a lighting signal in conjunction with the driving signal of a vehicle.

[0022] Referring to FIGS. 1 to 6, a detachable emergency warning plate (100) for preventing traffic accidents according to an embodiment of the present invention includes a body part (110), a lighting part (120), and a control part (130).

[0023] The body part (110) is formed in a plate shape and is attached to the vehicle (1). For example, the body part (110) may be attached to the outside of the vehicle (1) in the form of a magnet or to the inside of the trunk door (2), but is not necessarily limited thereto. The body part (110) may also be formed in a foldable form with a hinge structure in the center. The body part (110) is detachably connected to the vehicle (1) so that the user can detach it from the vehicle (1) and move it when necessary. This is to allow the user to move with the body part (110) to protect themselves in the event of an accident involving the vehicle (1).

[0024] Additionally, one side of the body part (110) is connected to the trunk door (2) so as to be rotatable. A rotatable bracket may be formed on one side of the body part (110). The body part (110) can rotate so that when the trunk door (2) is opened, the light-emitting surface on which the lighting part (120) is formed becomes perpendicular to the ground. This is to prevent the problem that the light-emitting surface is not properly visible when the body part (110) is fixed, as the opening angle of the trunk door (2) varies depending on the vehicle (1). As one side of the body part (110) is connected to the trunk door (2) so as to be rotatable, the rotation angle that unfolds according to the opening angle of the trunk door (2) is variable. Accordingly, the body part (110) can be universally used on various types of vehicles (1).

[0025] Additionally, the body portion (110) may be composed of an upper portion (110-1), a middle portion (110-2), and a lower portion (110-3). In this case, a plurality of middle portions (110-2) may be unfolded in an 'X' shape between the upper portion (110-1) and the lower portion (110-3). In FIG. 3, (a) shows the front view of the body portion (110) before unfolding, and (b) shows the back view of the body portion (1100) before unfolding. In FIG. 4, (a) shows the front view of the body portion (110) in an unfolded state, and (b) shows the back view of the body portion (1100) in an unfolded state.

[0026] The upper part (110-1), middle part (110-2), and lower part (110-3) of the body part (110) are formed with a plurality of links (110-4) and elongated holes (110-5), thereby facilitating movement as the middle part (110-2) unfolds or folds in an 'X' shape. When the body part (110) unfolds in an 'X' shape, the upper part (110-1) can be fixed to the trunk door (2) of the vehicle (1), and the lower part (110-3) can be fixed to the trunk floor. In this case, the lower part (110-3) can be fixed to various positions on the vehicle (1) by means of a rope or the like.

[0027] In this way, the body part (110) is separated into three sections and unfolds in an 'X' shape, allowing for a more effective warning to rear vehicles. Additionally, since it is installed on the inside of the vehicle (1) with the trunk door open rather than on the outside of the vehicle (1), it can be prevented from being ejected to the outside and causing a secondary accident.

[0028] Additionally, the body part (110) can be combined with an emergency vest (112). This is to allow the driver, who has left the vehicle (1), to attach the emergency warning sign (100) to their body while moving, thereby preventing secondary accidents. In this case, the driver may wear an X-band type reflective vest (112). It is desirable that the reflective vest (112) be luminous so that it can be visually identified even at night. The emergency warning sign (100) can be attached to the reflective vest (112) via a connector (111) such as Velcro or a magnet. This is to allow the driver to quickly carry the emergency warning sign (100) while moving.

[0030] The lighting unit (120) has a plurality of LEDs arranged in a pre-set pattern on the body unit (110). For example, the lighting unit (120) may be formed in the shape of an arrow such as '<' or '>', but is not necessarily limited thereto. The lighting unit (120) is controlled to blink by the control unit (130). It is preferable that the lighting unit (120) be arranged on the plane of the body unit (110) and be able to output multiple colors. The lighting unit (120) can prevent secondary accidents by acting as a turn signal to drivers on the road. It is also possible for the lighting unit (120) to blink only in a part of the area or for the blinking pattern to be variable by the control unit (130). The lighting unit (120) can be connected to a power line of the vehicle (1) to receive power, and in an emergency, it can be driven by an internal power source.

[0031] The control unit (130) outputs a warning signal through the lighting unit (120). In this case, the control unit (130) uses vehicle power when the body unit (110) is attached to the vehicle (1), and can drive the lighting unit (120) and sound unit (130) using internal power when the body unit (110) is detached from the vehicle (1). This is to allow the vehicle (1) power or internal power to be selectively used when the body unit (110) is detached from the vehicle (1). It is preferable that the internal power of the body unit (110) be composed of a rechargeable secondary battery that can be charged when connected to the vehicle power. Accordingly, the user can drive the lighting unit (120) and sound unit (130) using internal power even when the body unit (110) is detached from the vehicle (1) and carried around as needed.

[0032] In this way, a driver who has left the vehicle (1) can prevent a secondary accident by attaching the emergency warning sign (100) to their body while moving. For example, the emergency warning sign (100) can be attached to a reflective vest (112) via a connector (111) such as Velcro or a magnet. It is also possible for the emergency warning sign (100) to be electrically connected to the reflective vest (112). In this case, the reflective vest (112) may be formed with a lighting means (not shown), such as an optical fiber or an LED, and when electrically connected to the emergency warning sign (100), it is possible to output light through the lighting means. Accordingly, the safety of the driver can be ensured by expanding the means of outputting light to the emergency vest (112) in addition to the emergency warning sign (100).

[0033] Additionally, the control unit (130) can receive an operation signal of at least one of the brake light, turn signal, and emergency light of the vehicle (1) and output a lighting signal composed of a preset symbol or character through the lighting unit (120). In this case, the control unit (130) can receive a driving signal by being connected to the brake light, turn signal, and emergency light of the vehicle (1) via a wire through a connector formed in the body unit (110). The control unit (130) can display a symbol such as an arrow shape, a character, a figure, etc., on the lighting unit (120) according to the driving signal. This is intended to prevent accidents by additionally notifying the rear vehicle (1) of the driving signal corresponding to the brake light, turn signal, or emergency light.

[0035] FIGS. 5 and 6 are exemplary diagrams illustrating how a detachable emergency warning sign for preventing traffic accidents according to FIG. 2 communicates with an alarm.

[0036] Referring to FIGS. 5 and 6, a detachable emergency warning plate (100) for preventing traffic accidents according to another embodiment of the present invention may further include an alarm (140) and a communication unit (150).

[0037] The alarm (140) outputs a preset light and / or sound. The alarm (140) is attached to and detached from the body part (110). In this case, the alarm (140) is connected to one side of the body part (110). For example, it is possible for a magnetic material to be formed in the body part (110) and connected to the alarm (140) by magnetic coupling. In addition to being physically connected, the body part (110) and the alarm (140) can also be electrically connected. For example, the body part (110) can be charged by supplying power to the alarm (140) via a wireless method or a connector method.

[0038] Additionally, the alarm (140) outputs a preset sound. For example, the alarm (140) may be a piezo buzzer, but is not necessarily limited to this. The alarm (140) may also output a sound that is stored in memory. For example, the alarm (140) may output a sound such as "Help me (SOS)." The alarm (140) may also control the output of the sound using a jog dial. The alarm (140) may be controlled by the control unit (130) for its output.

[0039] Additionally, the alarm (140) may be stored attached to the body (110) or detached from the body and mounted inside the vehicle (1). In this case, the alarm (140) can be automatically charged when attached to the body (110). It is also desirable to have a wireless charging pad or an electric charging connector formed on the body (110). The alarm (140) outputs a sound of a level greater than a preset intensity. This is to allow a warning signal to be output to the outside to request rescue even if the doors of the vehicle (1) do not open in the event of a traffic accident.

[0040] Additionally, the alarm (140) may also output a driving signal for the lighting unit (120) through the communication unit (150). For example, the driving signal for the lighting unit (120) can be output through an operation button formed on the alarm (140). This is to allow the driver to open the trunk door (2) from inside the vehicle (1) and drive the lighting unit (120). In this case, the control unit (130) can drive the lighting unit (120) upon receiving the driving signal from the alarm (140). Accordingly, a warning signal can be quickly output through the lighting unit (120) without the driver having to get out of the vehicle.

[0041] Additionally, the alarm (140) may have a built-in location sensor to generate location information and transmit it through the communication unit (150). This is to notify the outside of the location information of the vehicle (1) or the driver. While operating, the alarm (140) generates location information at preset time intervals using a location sensor such as GPS. This location information is intended to allow nearby vehicles (1), insurance companies, control centers, etc., to easily check whether the vehicle (1) has been involved in an accident.

[0042] In this case, the control unit (130) can receive a driving signal from the communication unit (150) when the trunk door (2) of the vehicle (1) is opened and drive the lighting unit (120) and the alarm (140). The control unit (130) can determine whether the trunk door (2) of the vehicle (1) is open by being connected to the signal line, but is not necessarily limited to this. The lighting unit (120) displays a warning signal in the form of lighting, and the alarm (140) outputs a warning signal through the effects of lighting and sound. The alarm (140) has the effect of replacing a speaker by outputting sound of a preset intensity or higher. In this case, it is also possible for the lighting unit (120) and the alarm (140) to drive together with the warning signals synchronized with each other. Accordingly, when the trunk door (2) is opened, a warning signal can be quickly output through the lighting unit (120) and the alarm (140).

[0043] Additionally, the control unit (130) may receive a driving signal from the alarm (140) and output a warning signal in the form of a pre-set symbol or character through the lighting unit (120). For example, the control unit (130) can control the flashing signal of the lighting unit (120) through dimming control. The control unit (130) can output the warning signal through the lighting unit (120) and the alarm (140) and simultaneously transmit the warning signal to an external user terminal (10). In this case, the control unit (130) can use a GPS module to transmit location information along with the warning signal to the user terminal (10). This is intended to allow external police, etc., to quickly identify the location of the vehicle (1).

[0044] Meanwhile, the communication unit (150) can communicate with an external user terminal (10) or an alarm (140). Here, the external user terminal (10) may be a terminal used by a driver or an administrator such as a police station, fire station, or insurance company. The communication unit (150) can communicate via Bluetooth for short distances, and it is also possible to communicate via LoRa or LTE. The communication unit (150) can also communicate with the alarm (140). This is to allow the user to operate the lighting unit (120) or sound unit (130) of the vehicle (1) by using the alarm (140) like a remote control even when the user is located remotely. The communication unit (150) transmits a warning signal to the user terminal (10) at a preset time interval under the control of the control unit (130). Accordingly, a breakdown or traffic accident of the vehicle (1) can be quickly checked remotely.

[0046] Figure 7 is an example diagram illustrating the addition of a signal display unit to a detachable emergency warning plate for preventing traffic accidents according to Figure 2.

[0047] Referring to FIG. 7, the detachable emergency warning plate (100) for preventing traffic accidents according to an embodiment of the present invention may further include a signal display unit (160).

[0048] The signal display unit (160) outputs a flashing signal using a rod-shaped lighting means that rotates on both sides of the body unit (110). The signal display unit (160) is formed in a rod shape and can be configured as one or multiple units. Like the lighting unit (120), the signal display unit (160) uses an LED to flash and serves to attract the driver's attention. For example, the signal display unit (160) can be deployed from the body unit (110) in a triangular shape to function as a tripod. If the signal display unit (160) is formed in a fan shape on each side of the body unit (110), the flashing signals of each rod can be sequentially displayed to the driver, creating a visual effect such as the rods rotating. Additionally, it is possible for the signal display unit (160) to rotate the rods using a driving motor (not shown).

[0049] Meanwhile, the control unit (130) can determine the display range of the signal display unit (160) according to the driving signal. For example, if the signal display unit (160) is formed on both the left and right sides of the body unit (110), it is possible to select the left or right side for the flashing position. This is to induce the rear vehicle to change lanes. The control unit (130) can also control the direction of the signal display unit (160) according to the driving signal input from the alarm (140). In this case, it is preferable that the alarm (140) has an operation button formed to select the direction of the signal display unit (160). Accordingly, the rear driver's awareness can be heightened through the flashing signal displayed from the lighting unit (120) and the flashing signal displayed from the signal display unit (160), thereby preventing secondary traffic accidents.

[0051] Meanwhile, the detachable emergency warning sign (100) for preventing traffic accidents according to an embodiment of the present invention may further include a power generation unit (170). The power generation unit (170) can generate electricity and be used as a power source to drive the lighting unit (120), control unit (130), etc. For example, the power generation unit (170) may be formed in the form of a solar panel on one side of the body unit (110) to generate electricity from sunlight. In addition, the power generation unit (170) may generate electricity when pressure is applied using the piezoelectric effect. Furthermore, the power generation unit (170) may be implemented as a hand pump generator or a hand crank generator. This is intended to reduce the risk of battery discharge when the driver uses the emergency warning sign (100) from the outside for a long time. Accordingly, it is possible to generate power using self-power for a certain period of time without an external power supply and output a warning signal.

[0054] Although the present invention has been described above with reference to preferred embodiments described with reference to the drawings, it is not limited thereto. Accordingly, the present invention should be interpreted by the description of the claims, which is intended to encompass obvious variations derivable from the described embodiments.
