Description

Technology Field

[0001] The present invention relates to a method, device, and system for providing automated services for consultation guidance and repair processing related to vehicle accident reporting. More specifically, it relates to an accident scene response device that moves along the outer side of the vehicle at the accident scene during the service provision process and performs the function of automatically deploying and stacking strip-type fixing materials and reflector modules. Background Technology

[0003] Vehicle accidents frequently occur in various environments, including urban areas, highways, and parking lots, and the complexity of the procedures drivers must perform after an accident—such as accident reporting, initial response, consultation guidance, and repairs—has been consistently pointed out as a problem. In particular, immediately after an accident, drivers find it difficult to respond calmly due to variables such as impact, panic, and surrounding traffic flow; consequently, there are many cases where the accident reporting process is delayed or inaccurate. In such situations, the risk of secondary accidents increases as the accident vehicle itself obstructs the view of following vehicles or visibility is reduced during nighttime or rain. Accordingly, there is a growing need for automation technology that can ensure immediate visibility and safety at the scene of an accident while enabling the rapid processing of accident reporting and consultation guidance procedures.

[0004] In the insurance and auto repair industries, there is already a growing trend toward digitizing and automating all stages of the accident handling process, including accident reporting, on-site inspection, damage assessment, and repair assignment. While mobile app-based reporting, automatic analysis of accident scene photos, damage classification algorithms, and remote estimate technologies are becoming widespread, most of these functions rely on manual input, such as drivers taking photos or submitting documents themselves. Consequently, problems persist regarding the inconsistent quality of input data, inaccurate image capture of damaged areas, and the omission of critical information. In particular, since environmental factors such as the shape of the accident vehicle, surrounding obstacles, and shooting angles significantly impact the quality of input data, there are persistent calls for more stable automatic scanning and data collection technologies.

[0005] Meanwhile, various road safety devices, such as triangles, warning lights, and reflectors, have been used to ensure safety at accident scenes. While these devices are portable and easy for drivers to use, they pose a safety risk as they require the driver to exit the vehicle during installation, and their effectiveness in preventing secondary accidents is limited if the installation location is inappropriate. Some technologies have proposed methods to mark the perimeter of an accident vehicle by attaching belt-type markers or tape-type reflectors around the vehicle; however, these methods still have limitations, such as requiring manual attachment by the user and difficulty in wrapping them uniformly around the entire circumference of the vehicle. Furthermore, the degree to which following vehicles recognize the reflectors varies significantly depending on the attachment location or angle, leading to a persistent need for automated installation technology.

[0006] From a mechanical perspective, various technologies have been proposed regarding devices that automatically move along the perimeter of a vehicle to install safety devices. For instance, technologies utilizing mobile robotic platforms to patrol the vehicle for video recording or sensor scanning, and devices that grip and stabilize exterior panels have been discussed; however, most of these technologies are designed to perform only a specific purpose (such as recording, fixing, or safety marking) and are therefore insufficient for automating a comprehensive accident response process. In particular, technologies that simultaneously satisfy complex requirements—such as a compact structure immediately applicable at an accident scene, automatic movement control, positional alignment based on both side mirrors, and ensuring rear visibility—have rarely been proposed.

[0007] The method of scanning the condition of accident vehicles and linking this with accident reporting and consultation guidance services has also not been sufficiently implemented in existing technologies. While some studies have proposed machine vision-based algorithms to automatically analyze damage to vehicle exterior panels, cases combined with mobile devices usable at actual accident scenes are rare, and there is also a lack of technology to link on-site scan results with insurance company systems or consultation guidance services in real time. This stems from a structural problem where the accident processing is separated into multiple independent systems, and the primary cause is the lack of integrated data flow between devices automating vehicle-related tasks and accident reporting services.

[0008] The problems with the existing prior art can be summarized as follows.

[0009] First, there is a safety issue in that the driver must manually perform the installation work at a dangerous location due to the lack of mechanical means to automatically install safety devices around the accident vehicle.

[0010] Second, due to the low technical maturity of robotic devices that track the vehicle at a uniform distance and move along an accurate path, there was a lack of automation technology for regularly attaching reflective or fixed materials along the outer side of the vehicle.

[0011] Third, reflectors or LED-based devices for ensuring visibility exist individually, but a systemic structure is not provided to continuously ensure rear visibility in conjunction with the deployment process of the fixed device.

[0012] Fourth, no device has been proposed that integrates the accident vehicle exterior scanning function with the installation function of fixed materials and reflectors, and technology for automatically linking the shooting and scanning results with the accident reporting and consultation guidance system has also been lacking.

[0013] In summary, on-site response efficiency remains low because safety at accident scenes, automated installation of fixed materials and reflectors, scan-based damage information collection, and linkage with accident reporting services are not seamlessly integrated into a single system. Consequently, there is a significant demand for improvements in terms of worker safety, data quality, and processing speed. The industry has consistently called for a new type of accident response device capable of immediately performing key elements of automated services—such as accident reporting, consultation guidance, and repair processing—on-site. In particular, there is a demand for the introduction of technology that can autonomously move around vehicles to simultaneously deploy safety devices and collect accident information.

[0016] The present invention was made to solve the problems described in the background technology above.

[0017] First, immediately after a vehicle accident, damaged areas remain exposed on the exterior of the vehicle, posing a high risk of secondary accidents and making it difficult for drivers approaching the rear of the vehicle to immediately assess the accident situation. In particular, visibility is severely reduced in nighttime and adverse weather conditions, requiring additional devices to safely secure the area around the accident scene.

[0018] Second, post-accident response processes, such as accident reporting, consultation guidance, and repair processing, are mostly performed manually by the driver, leading to time delays and a problem where the efficiency of the accident reporting process is reduced due to the inaccurate transmission of accident scene information.

[0019] Third, existing accident response technologies primarily rely on simple warning measures such as flashing lights, triangles, and hazard lights, or transmit accident situations to rear vehicles via in-vehicle electronic devices; consequently, they have failed to provide functions that structurally protect damaged areas or mechanically ensure rear visibility.

[0020] Fourth, there was a problem in that human intervention could not be minimized at accident scenes with high safety risks, as drivers often had to install fixed devices or warning signs on the outside of the vehicle themselves.

[0021] To solve these problems, a structural and mechanical device is required that can (1) be installed immediately along the outer side of the accident vehicle, (2) temporarily fix the damaged area, (3) provide high visibility from the rear, (4) automatically collect data linked to accident reporting and consultation guidance, and (5) operate automatically without driver intervention.

[0022] To meet these requirements, the present invention provides an accident scene response device capable of deploying a strip-type fixing material and stacking reflector modules while moving along the outer side of the accident vehicle, and simultaneously acquiring scan data of the accident area, thereby integrally implementing the entire process of protecting the damaged part of the accident vehicle, preventing secondary accidents, and automating accident reporting. means of solving the problem

Next, the safety cart is fixed near the side mirrors on both sides of the accident vehicle. It can be classified into a fixed cart consisting of a first cart and a second cart that are positioned, and a mobile cart that reciprocates between the first cart and the second cart, pulling and unwinding the strip-type fixing material and reflector module wound and received in the first cartridge and the second cartridge, respectively. The fixed cart may include a main body platform in the shape of a rectangular column that is vertically erected in the outer area of ​​the side mirror when viewed from the rear of the accident vehicle toward the front, and a gripping receiving portion in the shape of a groove that is recessed in the same direction as the direction in which the side mirror protrudes on one side of the main body platform. The cartridge winding portion may be partitioned in the left and right directions so that the strip-type fixing material and reflector module are received in a horizontal position while wound. The gripping receiving portion includes a gripping space for receiving the outer side of the side mirror, a flip-type gripping portion positioned at the entrance of the gripping space to grip the side mirror elastically rotatable, andIt may include an elastic hinge that pivotally supports the flip-type gripping part and provides a restoring force. The cartridge winding part may be positioned in a direction adjacent to the accident vehicle where the gripping receiving part is formed. It may include a first mounting area where a first cartridge, which is received lying down in a wound state, is placed, and a second mounting area positioned on the opposite side (outer side) of the first mounting area and receiving the second cartridge. The mobile cart may include a main body platform with a wheel-based driving part positioned at the bottom, a tension maintaining sensor for detecting tension when unwinding the strip-type fixing material, a scan module positioned on one side of the main body platform facing the direction of the accident vehicle to scan while moving over the accident site, and a cartridge unwinding part for gripping and pulling the end of the wound material exposed in the first mounting area or the second mounting area. The wound material may be defined as the strip-type fixing material or the reflector module. The cartridge unwinding unit may include an elastic movement space provided as a predetermined space in a manner penetrating the main body platform, a V-shaped guide surface installed in the elastic movement space and positioned to face the rear direction of the moving cart, a gripping bar formed in the vertical direction in the area where the V-shaped guide surfaces merge, and a gripping groove formed in the gripping bar into which the end of the wound material is inserted. The V-shaped guide surface may be divided into a V-shaped guide surface including a first branched guide surface branched toward the first mounting area and a second branched guide surface branched toward the second mounting area. The cartridge unwinding unit may further include guide rails provided at the top and bottom of the elastic movement space, respectively. Both ends of the gripping bar may be mounted on the guide rails in a manner that allows them to move left and right. The cartridge unwinding unit includes a left end detection sensor and a right end detection sensor for detecting the presence of the end of the wound material exposed in the first mounting area or the second mounting area, respectively, and a docking detection sensor for detecting that the rear of the moving cart has come into contact with the fixed cart, andThe apparatus may further include a gripping position determining actuator that determines the left and right positions of the gripping bar so that the gripping bar moves in a direction selected between the first branch guide surface direction and the second branch guide surface direction according to the detection signal of the left end detection sensor or the right end detection sensor, and an inflow pressurizing actuator that, when the docking detection sensor is activated, displaces the front end of the gripping bar forward by a predetermined amount so that the end of the wound material naturally flows into the gripping groove. The shooting angle of the scan module may be arranged to maintain the direction of the accident vehicle when the moving cart travels along the outside of the accident vehicle. The moving cart may be moved to be pulled while maintaining tension to prevent the wound material gripped by the cartridge unwinding unit from twisting during travel. It is characterized by the fact that the end of the wound material of either the first cartridge or the second cartridge can be approached and gripped in a direction selected between the left and right directions by means of the left and right movement structure of the gripping bar in the elastic movement space.

[0026] Next, the cartridge winding unit may further include a drawer-type storage means provided such that the second mounting area can be withdrawn outwardly toward the main body platform. The drawer-type storage means may include a withdrawal tray arranged to slide outwardly toward the main body platform, a sliding guide rail guiding a straight withdrawal path of the withdrawal tray, and a locking latch for fixing the position of the withdrawal tray when it is withdrawn. When the drawer-type storage means is withdrawn, the second cartridge may be positioned in a state protruding outwardly toward the main body platform. The elastic movement space may be divided into a selective movement space having a relatively narrow movement range so that the gripping bar of the cartridge unwinding part of the moving cart can be aligned with either the end of the winding of the first cartridge or the end of the winding of the second cartridge, and an expanded movement space having an expanded left-right movement range corresponding to the amount of withdrawal of the withdrawal tray so that the gripping bar of the cartridge unwinding part of the moving cart can be aligned with either the end of the winding of the first cartridge or the end of the winding of the second cartridge withdrawn. As the second cartridge protrudes to the outside of the main body platform through the drawer-type storage means, the reflector module attached to the strip-type fixing material is positioned to have a larger projection width from a rear viewpoint than the outside of the strip-type fixing material, thereby inducing increased visibility by widening the exposed area of ​​the reflector module when viewed from the rear of the accident vehicle.

[0027] Next, the main body platform of the fixed cart and the main body platform of the mobile cart may be provided with a temporary reflection module composed of a plurality of LED cells to ensure visibility from the rear of the accident vehicle. The temporary reflection module may include an LED cell array, an LED driving circuit for driving the LED cells, and a proximity sensor for detecting when the side mirror enters the gripping space. The cell array of the fixed cart may be positioned to avoid the gripping space of the gripping receiving portion and simultaneously positioned in a fixed direction facing the rear of the accident vehicle. The cell array of the mobile cart may be arranged in a rectangular matrix form on the upper part of the main body platform. The mobile cart may be driven by controlling the driving direction or rotation angle so that the rotation angle during driving faces the rear of the accident vehicle, thereby ensuring that the cell array of the mobile cart always faces the rear of the accident vehicle even while the mobile cart is moving back and forth. The LED driving circuit is controlled to light up the temporary reflective module of the fixed cart and the movable cart when the proximity sensor detects the approach of the side mirror, thereby providing temporary visibility identifiable from the rear even before the reflective module is attached to the strip-shaped fixing material.

[0028] Next, the accident scene response device for the automated service for consultation guidance and repair processing related to the vehicle accident report may further include a control unit for controlling the driving of the mobile cart, the gripping and towing operation of the cartridge unwinding unit, the lighting pattern control of the LED cell array, and the image acquisition operation of the scan module in conjunction. The control unit may include a driving control means that controls the forward and backward driving and rotation angles of the mobile cart so that the cell array of the mobile cart always faces the rear of the accident vehicle while the mobile cart moves back and forth along the outer side of the accident vehicle; a gripping and towing control means that performs left-right movement of the gripping bar of the cartridge unwinding unit for gripping the ends of the wound material of the first cartridge and the second cartridge, the inflow operation of the gripping groove, and tension maintenance control for towing the wound material; and an LED scan synchronization control means that determines the lighting pattern of the LED cell array of the fixed cart and the mobile cart and synchronizes the image acquisition time of the scan module in response to the detection signal of the proximity sensor, the shooting timing of the scan module, and the unwinding progress state of the cartridge unwinding unit. With the two fixed carts mounted at the positions of the side mirrors on both sides of the accident vehicle, the temporary reflective modules of the fixed cart and the movable cart can be controlled to light up according to the detection signal of the proximity sensor. The end of the strip-shaped fixing material exposed from the first cartridge can be controlled to be fed into and gripped in the gripping groove of the cartridge ejection part through the gripping traction control means. In the starting operation to move the movable cart from one side of the accident vehicle to the other side via the rear, the forward movement, rotation angle, and approach distance of the movable cart can be controlled by the driving control means so that the strip-shaped fixing material is kept in close contact with the outer surface of the accident vehicle. After reaching the fixed cart on the opposite side, the drawer-type storage means of the second mounting area can be controlled in conjunction with the gripping traction control means so that it is pulled out.When the end of the reflector module is exposed in the second cartridge withdrawn above, the end of the reflector module can be controlled to be gripped in the gripping groove through the gripping traction control means. While the mobile cart is returning to the starting point from the other side of the accident vehicle, the driving control means can be used to maintain a rotation angle so that the mobile cart faces the rear of the accident vehicle. The reflector module can be controlled to return along a 'U'-shaped path so that it is Velcro-coupled to the outer side of the strip-shaped fixing material. During all traction processes of the strip-shaped fixing material and the reflector module, the tension of the wound material is controlled to be maintained within a certain range through the gripping traction control means, thereby enabling the entire operation to be controlled in conjunction so that the strip-shaped fixing material and the reflector module are sequentially unwound and stacked along the outer side of the accident vehicle. Effects of the invention

[0030] According to the present invention, the following effects are achieved.

[0031] First, through a stacked structure of a strip-type fixing material and a reflector module that automatically deploys along the outer side of the accident vehicle, the damaged area can be physically protected while significantly improving rear visibility. In particular, based on the outer withdrawal structure and expanded movement space of the second cartridge, the projection width of the reflector module is expanded, allowing vehicles approaching from the rear to identify the accident scene early, thereby substantially reducing the risk of secondary accidents.

[0032] Second, the fixed cart and the mobile cart are automatically mounted near the side mirror, and the mobile cart sequentially deploys the strip-type fixed material and the reflector module through reciprocal driving, so the response to the accident scene is performed automatically without driver intervention, thereby eliminating human risk factors in safety securing work immediately after an accident.

[0033] Third, since image and shape data captured and scanned along the outer part of the accident vehicle (especially the damaged area) by the scan module are synchronized and secured by the control unit, information such as the condition of the accident site, type of damage, collision angle, and extent of damage is automatically collected and transmitted at the accident reporting stage, enabling rapid and accurate accident investigation and repair estimate estimation.

[0034] Fourth, temporary reflective modules (LED cell arrays) are installed on the fixed cart and the mobile cart, respectively, and light up immediately upon detection of the side mirror, thereby enabling temporary visibility of the rear of the accident vehicle even before the reflective module stacking stage. This plays an important role in preventing additional accidents at the most dangerous moment immediately after an impact.

[0035] Fifth, through the interlocking operation of a control unit in which driving control means, gripping towing control means, and LED scan synchronization control means are integrated, the entire process, including strip-type fixing material deployment → reflector module deployment → image scanning → return path control, is automated, making it possible to implement a one-stop integrated process that is organically linked with accident reporting consultation guidance and repair processing automation services.

[0036] Sixth, unlike simple warning devices or tripod-type warning boards, the device of the present invention has a structure combining a strip-type fixed material + a reflector module + scan data + an automatic driving mechanism, so it provides a new accident response pattern based on mechanical and physical principles that could not be provided by existing technology, and thus is expected to have a high technological and economic impact in industrial sites.

[0060] FIG. 6 is a block diagram of a control unit for controlling the driving of a moving cart, the gripping and pulling operation of a cartridge ejection unit, the lighting pattern control of an LED cell array, and the image acquisition operation of a scan module in conjunction.

[0062] In an accident scene response device for automated services regarding consultation guidance and repair processing related to vehicle accident reporting according to the present invention, a safety cart (100) configured to move along the periphery of the accident vehicle, and a cartridge winding unit (300) that can be mounted on the safety cart (100) and accommodates a plurality of cartridges wound thereon.

[0063] The cartridge winding section (300) may be equipped with a first cartridge in which a strip-shaped fixing material (321) that unfolds along the perimeter of the accident vehicle as the safety cart (100) moves is received in a wound state, and a second cartridge in which a reflector module (322) that is sequentially stacked along the unfolded strip-shaped fixing material (321) as the safety cart (100) moves is received in a wound state.

[0064] The above safety cart (100) is characterized by moving back and forth along a path formed from one side of the accident vehicle through the rear to the other side, and reflector modules (322) unwound from the second cartridge are sequentially attached to Velcro members provided on the outer surface of the strip-shaped fixing material (321).

[0066] Next, the safety cart (100) may be divided into a fixed cart (110) consisting of a first cart and a second cart that are fixedly positioned near the side mirrors of the accident vehicle, and a moving cart (120) that moves back and forth between the first cart and the second cart, pulling and unwinding a strip-shaped fixing material (321) and a reflector module (322) that are wound and received in the first cartridge and the second cartridge, respectively.

[0067] The above fixed cart (110) may include a rectangular column-shaped main body platform (700) that is vertically erected in the outer area of ​​the side mirror when viewed from the rear of the accident vehicle toward the front, and a groove-shaped gripping receiving portion (200) that is recessed in the same direction as the direction in which the side mirror protrudes on one side of the main body platform (700).

[0068] The cartridge winding section (300) can be partitioned in the left and right directions so that the strip-shaped fixing material (321) and the reflector module (322) are received lying down in a wound state.

[0069] The above gripping receiving portion (200) may include a gripping space (210) for receiving the outer side of the side mirror, a flip-type gripping portion (220) positioned at the entrance of the gripping space (210) to grip the side mirror elastically, and an elastic hinge (230) that supports the flip-type gripping portion (220) rotationally and provides a restoring force.

[0070] The cartridge winding section (300) may be positioned in a direction adjacent to the accident vehicle where the gripping receiving section (200) is formed. It may include a first mounting area (311) on which a first cartridge is placed and received while lying down in a wound state, and a second mounting area (312) positioned on the opposite side (outer side) of the first mounting area (311) and on which the second cartridge is received.

[0071] The above-mentioned mobile cart (120) may include a main body platform (700) having a wheel-based driving unit (710) positioned at the bottom, a tension-maintaining sensor for detecting tension when unwinding the strip-shaped fixing material (321), a scan module (121) positioned on one side of the main body platform (700) facing the direction of the accident vehicle and scanning the accident area while moving, and a cartridge unwinding unit (400) for gripping and pulling the end of the wound material exposed in the first mounting area (311) or the second mounting area (312).

[0072] The above-mentioned coil may be defined as the above-mentioned strip-shaped fixing material (321) or the above-mentioned reflector module (322).

[0073] The cartridge unwinding section (400) may include an elastic moving space (410) provided as a predetermined space in a form penetrating the main body platform (700), a V-shaped guide surface installed in the elastic moving space (410) and positioned to face the rear direction of the moving cart (120), a gripping bar (420) formed in a vertical direction in an area where the V-shaped guide surface joins, and a gripping groove (430) formed in the gripping bar (420) into which the end of the wound material is inserted.

[0074] The above V-shaped guide surface may be divided into a first branch guide surface branched toward the first mounting area (311) and a second branch guide surface branched toward the second mounting area (312).

[0075] The cartridge ejection unit (400) may further include guide rails (440) provided at the top and bottom of the elastic movement space (410), respectively.

[0076] Both ends of the gripping bar (420) can be mounted on the guide rail (440) in a manner that allows them to move left and right.

[0077] The cartridge unwinding unit (400) may further include a left end detection sensor and a right end detection sensor for detecting the presence of a wound end exposed in the first mounting area (311) or the second mounting area (312), respectively; a docking detection sensor for detecting that the rear surface of the moving cart (120) is in contact with the fixed cart (110); a gripping position determining actuator for determining the left and right positions of the gripping bar (420) so that the gripping bar (420) moves in a selected direction between the first branch guide surface direction or the second branch guide surface direction according to the detection signal of the left end detection sensor or the right end detection sensor; and an inflow pressurizing actuator for displacing the front end of the gripping bar (420) forward by a predetermined amount when the docking detection sensor is activated so that the wound end naturally flows into the gripping groove (430).

[0078] The shooting angle of the above scan module (121) can be arranged to maintain the direction of the accident vehicle when the moving cart (120) travels along the outside of the accident vehicle.

[0079] The above-mentioned moving cart (120) can be moved to maintain tension and tow the wound material held by the cartridge unwinding unit (400) so as not to twist while driving.

[0080] It is characterized by the fact that, by the left-right movement structure in the elastic movement space (410) of the gripping bar (420), the end of the wound material of either the first cartridge or the second cartridge can be approached and gripped in a selected direction among the left and right directions.

[0081] The accident scene response device according to the present embodiment may be implemented in a structure comprising a safety cart (100) that automatically moves along the outer perimeter of the accident vehicle and deploys a strip-shaped fixing material (321) and a reflector module (322), and a cartridge winding unit (300) mounted on the safety cart (100). At this time, the safety cart (100) is preferably configured in a form consisting of a pair of fixed carts (110) fixed to the side mirrors on both sides of the accident vehicle and a moving cart (120) that moves back and forth between them.

[0082] The strip-shaped fixing material (321) (first cartridge winding) used in this embodiment may be made of a flexible plastic or synthetic fiber sheet with a thickness of about 1 to 2 mm and a width of 40 to 80 mm, and a nylon-based Velcro loop layer may be attached at regular intervals to the outer surface. The reflector module (322) (second cartridge winding) is made of soft PET material or acrylic reflective sheets with a thickness of about 1 mm, and a Velcro hook layer is provided on the back of these sheets so that it can be mechanically coupled with the Velcro loop layer on the outer surface of the strip-shaped fixing material (321).

[0083] The fixed cart (110) includes an upright rectangular prism-shaped main body platform (700) positioned at the lower outer side of the side mirror of the accident vehicle. The main body platform (700) may be made of aluminum plate with a thickness of 3 to 5 mm or reinforced plastic (e.g., polycarbonate) so as not to deform upon contact with or collision with a damaged area, and the height may be implemented within the range of approximately 250 to 350 mm.

[0084] On the side of the main body platform (700) facing the accident vehicle, a recessed gripping receiving portion (200) is formed so that a side mirror can be inserted. The gripping receiving portion (200) is formed in the shape of a groove with an open front, and the internal width is preferably in the range of approximately 60 to 120 mm based on the outer bottom width of a standard passenger car side mirror. Flip-type gripping portions (220) are arranged on both sides of the entrance of the gripping space (210), and the flip-type gripping portions (220) are supported by two synthetic resin flaps with a thickness of 2 to 3 mm on both side walls of the gripping space (210), and each flap is rotatably mounted via a stainless steel wire or an elastic hinge (230) made of an elastomer material having a restoring force. The flip-type gripping portions (220) open when the side mirror is inserted and, after insertion, restore to wrap around the bottom of the mirror to serve to stably secure it inside the gripping space (210).

[0085] The cartridge winding section (300) is formed on the side opposite the side of the main body platform (700) in a left-right partitioned state. In the innermost first mounting area (311), a first cartridge with a strip-shaped fixing material (321) wound on it is placed horizontally. At this time, the cartridge may be manufactured with a cylindrical or flat winding structure, and a form in which a strip-shaped fixing material (321) is wound around a core with a diameter of approximately 100 to 200 mm is suitable. A second cartridge of the same structure is placed on the outer side, and a reflector module (322) is received in a state where it is wound in the same manner. A separation partition with a width of 10 to 20 mm may be installed between the two areas to prevent interference.

[0086] The mobile cart (120) includes a wheel-based driving unit (710) at the bottom that can be driven independently on the left and right sides. Each wheel is formed of rubber or urethane material with a diameter of 50 to 80 mm and can be controlled to move forward, backward, and rotate via a servo motor. A main body platform (700) with a height of 200 to 300 mm is erected on the driving unit (710), and a scan module (121) is mounted on the front of the platform (on the side facing the accident vehicle).

[0087] The scan module (121) may be in the form of an optical camera or a ToF-based distance measuring sensor. The camera is fixed at a downward angle of about 15 to 25 degrees relative to the ground so as to face the accident vehicle even while driving, and continuously photographs the side of the vehicle and the damaged area as the moving cart (120) moves.

[0088] A cartridge ejection unit (400) is positioned at the rear of the moving cart (120). The ejection unit is formed to penetrate the rear of the main body platform (700), and an elastic movement space (410) capable of being displaced in the left and right directions is provided inside. Guide rails (440) are positioned along the top and bottom of the elastic movement space (410), and the gripping bar (420) is configured to move left and right along these guide rails (440).

[0089] The gripping bar (420) is a structure in which a longitudinal groove is formed in a rigid metal rod (e.g., aluminum rod), and this groove is used as a gripping groove (430). The gripping groove (430) is formed with a width of 5 to 10 mm so that the end of the wound material can be naturally inserted when fed along the V-shaped guide surface, and the interior may be coated with rubber to prevent slipping.

[0090] A V-shaped guide surface is formed on the front of the elastic moving space (410) facing the rear direction of the moving cart (120). This guide surface is composed of a first branch guide surface that branches toward the first cartridge and a second branch guide surface that branches toward the second cartridge, so that the end of the wound material can be guided to the gripping groove (430) from either direction.

[0091] A left end detection sensor and a right end detection sensor are installed on the moving cart (120) to determine which end of the winding material is exposed among the first and second cartridges. Additionally, a docking detection sensor is placed on the rear of the main body to detect that the rear of the moving cart (120) is in close contact with the fixed cart (110). When docking is detected, an inflow pressurizing actuator displaces the gripping bar (420) forward by about 3 to 8 mm so that the end of the winding material naturally enters the gripping groove (430).

[0092] The internal control module of the moving cart (120) receives real-time tension data from the tension maintenance sensor and adjusts the wheel drive speed so that the wound material does not become excessively loose or tense while driving. This prevents twisting or detachment of the strip-shaped fixing material (321) or the reflector module (322) while driving.

[0093] To use the device, two fixed carts (110) are attached to the bottom of the side mirrors on both sides of the accident vehicle. When inserting, the flip-type gripping part (220) rotates, and when the side mirror is fully inserted into the gripping space (210), the flip-type gripping part (220) closes again through restoring force and is fixed. Afterwards, the moving cart (120) starts from one of the fixed carts (110), and the cartridge ejection part (400) grips the end of the first cartridge and pulls the strip-type fixing material (321).

[0094] While the moving cart (120) moves along the perimeter of the accident vehicle, passing through the rear, to the opposite fixed cart (110), the strip-shaped fixing material (321) is deployed in close contact with the outer surface of the vehicle. Upon reaching the opposite side, the end of the second cartridge winding material is grasped, and as the moving cart (120) returns in the opposite direction, the reflector module (322) is sequentially stacked on the outer side of the strip-shaped fixing material (321) using a Velcro connection method.

[0095] All components in this embodiment adopt mechanically and physically natural structures to enable actual manufacturing, and the combination and operation between components are in a form that can be sufficiently implemented at the level of small industrial automation equipment.

[0097] Next, the cartridge winding portion (300) may further include a drawer-type storage means (330) provided so that the second mounting area (312) can be pulled out toward the outside of the main body platform (700).

[0098] The above drawer-type storage means (330) may include a pull-out tray arranged to slide outwardly toward the main body platform (700), a sliding guide rail guiding a straight pull-out path of the pull-out tray, and a locking latch for fixing the position of the pull-out tray when it is pulled out.

[0099] When the above drawer-type storage means (330) is withdrawn, the second cartridge may be positioned so as to protrude outward from the main body platform (700).

[0100] The elastic movement space (410) may be divided into a selective movement space having a relatively narrow movement range so that the gripping bar (420) of the cartridge unwinding section (400) of the moving cart (120) can be aligned with either the end of the winding of the first cartridge or the end of the winding of the second cartridge, and an expanded movement space having a left-right movement range expanded in correspondence with the amount of the second cartridge drawn out so that the gripping bar (420) of the cartridge unwinding section (400) of the moving cart (120) can be aligned with either the end of the winding of the first cartridge or the end of the winding of the second cartridge drawn out.

[0101] As the second cartridge protrudes outward from the main body platform (700) through the drawer-type storage means (330), the reflector module (322) attached to the strip-type fixing material (321) is positioned to have a larger projection width from a rear viewpoint than the outer side of the strip-type fixing material (321), thereby inducing increased visibility by widening the exposed area of ​​the reflector module (322) when viewed from the rear of the accident vehicle.

[0102] The cartridge winding unit (300) according to the present embodiment includes a drawer-type storage means (330) configured such that the second mounting area (312) can be drawn out toward the outside of the main body platform (700). The drawer-type storage means (330) is based on a sliding carrier structure used in general industrial equipment and is manufactured by combining metal and high-strength synthetic resin so as not to deform even with repeated use.

[0103] The pull-out tray of the drawer-type storage means (330) can be formed as a rectangular plate structure with a length of 150 to 250 mm and a width of 80 to 150 mm, and sufficient rigidity can be secured by using an aluminum extruded material or a polycarbonate reinforced panel. A ball bearing type or roller type sliding guide rail is attached to the bottom or both sides of the pull-out tray. The sliding guide rail consists of a fixed rail fixed to the side of the main body platform (700) and a movable rail fixed to the pull-out tray, and guides the tray to be pulled out in a straight direction through a combination of a pair of rails. Considering the durability of the guide rail, the rail housing can be formed of stainless steel or anodized aluminum with a thickness of 1 mm or more.

[0104] A locking latch is installed at the end of the withdrawal so that outward shaking does not occur when the withdrawal tray is in a fully withdrawn position. The locking latch may adopt a spring-return type locking pin structure and is coupled with a locking hole formed on the side of the withdrawal tray to maintain the withdrawn state. Since the end of the second cartridge withdrawn by the operation of the moving cart (120) during use must be stably exposed, the locking latch is designed to provide a withdrawal resistance in the range of 3 to 5 kgf so that it is not unexpectedly pushed in by external force.

[0105] As the drawer-type storage means (330) is pulled out, the second cartridge may protrude about 50 to 120 mm to the outside of the main body platform (700). The weight of the second cartridge varies depending on the amount of reflector module (322) wound, but is generally in the range of 300 to 800 g, and this weight can be sufficiently supported within the load tolerance range of the pull-out tray and guide rail.

[0106] The elastic movement space (410) of the cartridge ejection unit (400) is configured to be divided into two sections. The selective movement space is a basic left-right movement area used when both the first cartridge and the second cartridge are within the range of the main body platform (700), and the left-right movement range is limited to approximately 15 to 30 mm. The selective movement space provides a minimum movement range designed to allow the moving cart (120) to grasp the end of the first cartridge immediately after docking with the fixed cart (110).

[0107] On the other hand, the extended movement space is used when the drawer-type storage means (330) is withdrawn and the second cartridge is moved outward, and provides a significantly wider range of movement than the selected movement space. The left and right movement range of the extended movement space is extended to about 40 to 70 mm, which corresponds to the amount of outward movement of the withdrawal tray. The extended movement space can be implemented through a structure in which the guide rail (440) is extended or through an interlocking sliding rail, allowing the gripping bar (420) to accurately approach the end position of the second cartridge that has been withdrawn. The extension of the guide rail (440) can be secured by slightly bending the lower rail backward or connecting the upper rail to the extension fixing part so as not to infringe upon the internal structure of the main body platform (700).

[0108] In this embodiment, when the drawer-type storage means (330) is drawn out, the second cartridge protrudes outward from the main body platform (700), and the reflector module (322) is positioned further outward than the strip-type fixing material (321). This arrangement results in an effect where the projection width is widened when viewing the reflector module (322) from the rear of the accident vehicle. Physically, this is because the center axis of the reflector module (322) moves outward from the center axis of the strip-type fixing material (321), thereby increasing the width of the projected cross-section formed from the rear viewpoint; thus, even with a reflector module (322) of the same width, rear visibility is improved through the outward placement. For example, if the reflector module (322) moves 60 mm outward relative to the centerline of the strip-type fixing material (321), the projection width from the rear can increase by at least 10-15%, which provides a functional effect of improving the possibility of recognizing an accident at night or in adverse weather conditions.

[0109] Accordingly, in this embodiment, through the configuration of the drawer-type storage means (330), the selective movement space, and the extended movement space, and their interconnected operation, the moving cart (120) can not only stably grip and pull both the first cartridge and the pulled-out second cartridge, but also provide additional technical effects such as improving rear visibility by adjusting the placement position of the reflector module (322).

[0111] Next, the main body platform (700) of the fixed cart (110) and the main body platform (700) of the mobile cart (120) may be provided with a temporary reflective module (500) composed of a plurality of LED cells to ensure visibility from the rear of the accident vehicle.

[0112] The above temporary reflection module (500) may include an LED cell array, an LED driving circuit for driving the LED cells, and a proximity sensor for detecting when the side mirror enters the gripping space (210).

[0113] The cell array of the fixed cart (110) can be positioned to avoid the gripping space (210) of the gripping receiving part (200) and at the same time be positioned in a fixed direction toward the rear of the accident vehicle.

[0114] The cell array of the above-mentioned moving cart (120) can be arranged in a rectangular matrix form on the upper part of the main body platform (700).

[0115] The above-mentioned mobile cart (120) can be driven such that the driving direction or rotation angle is controlled so that the rotation angle of the mobile cart (120) is directed toward the rear of the accident vehicle during driving, and the cell array of the mobile cart (120) is always directed toward the rear of the accident vehicle even while the mobile cart (120) is moving back and forth.

[0116] The LED driving circuit is controlled to light up the temporary reflection module (500) of the fixed cart (110) and the moving cart (120) when the proximity sensor detects the approach of the side mirror, thereby providing temporary visibility that is identifiable from the rear even before the reflector module (322) is attached to the strip-shaped fixing material (321).

[0117] The accident site response device according to the present embodiment includes a temporary reflection module (500) for ensuring visibility from the rear of the accident vehicle on each of the fixed cart (110) and the mobile cart (120). The temporary reflection module (500) is composed of a plurality of LED cells and is designed to ensure sufficient visibility even at night or in adverse weather conditions by using high-brightness SMD type LEDs (e.g., 2835 standard or 3030 standard) that can achieve high brightness even with low power consumption. The brightness of the LED cells can be set to a level of 50 to 120 lm and is wired in a mixed series-parallel arrangement considering the mounting location and power consumption.

[0118] The LED cell array of the temporary reflection module (500) can be configured in the form of a rectangular matrix panel in which LED cells are arranged in a 4×6 or 5×8 array. The substrate of the LED cell array can be formed on an aluminum core PCB or a heat-resistant FR-4 substrate that facilitates heat dissipation, and a heat dissipation pad or heat dissipation block is additionally attached to the back of the substrate to minimize the temperature rise of the LEDs even when illuminated for a long time.

[0119] An LED cell array installed on a fixed cart (110) is attached to an outer frame surrounding the gripping space (210) to prevent structural interference around the gripping receiving portion (200), and the light-emitting surface of the LED is fixed at an angle so as to face the rear of the accident vehicle. To this end, the LED panel can be installed at an angle of approximately 85-95 degrees toward the rear, and the mount bracket is made of ABS or PC-ABS molded material to withstand external impact. The LED module installation positions on the fixed cart (110) are balanced on the left and right outer edges avoiding the gripping receiving portion (200), so that glare caused by direct light interference is minimized even when a worker approaches near the side mirror.

[0120] The LED cell array installed on the moving cart (120) is formed as a flat rectangular panel structure to secure a large surface area on the top of the main body platform (700). This is to maximize visibility in the rear direction within 360° even while moving, and the LED cell array is fixed horizontally to the central axis of the moving cart (120). The panel size can be designed in the range of approximately 120×220 mm or 150×250 mm. Considering external impact, the LED panel is covered with a translucent anti-reflective cover (e.g., a polycarbonate cover) to widen the directionality of the LEDs and provide uniform visibility at various distances through the dispersion of light.

[0121] The control of the temporary reflection module (500) is performed through an LED driving circuit. The LED driving circuit is based on a 12V or 24V DC input and may be equipped with a constant current driver IC for stable current supply. The detection signal of the proximity sensor is connected to the trigger input of the LED driving circuit, and is designed so that the LED lighting mode is activated immediately when the trigger signal is detected. The proximity sensor can use a non-contact optical sensor or an infrared-based proximity sensor to detect the moment when the side mirror enters the gripping space (210) at a distance of 2 to 5 cm. The detection value of the sensor is converted into a digital signal and transmitted to the LED driving circuit.

[0122] When the proximity sensor detects the presence of the side mirror, the LED cell arrays of the fixed cart (110) and the moving cart (120) are illuminated simultaneously. The lighting pattern can be selected from either continuous lighting or a flashing pattern at a low frequency (about 2-3 Hz). The flashing pattern is a method that can induce stronger visual attention to other vehicles passing around the accident vehicle.

[0123] The movement cart (120) has its movement path and rotation angle adjusted by a driving control system, and is controlled so that the LED cell array always faces the rear of the accident vehicle even while moving. This function can be implemented based on the value of a direction angle sensor (electronic compass or IMU-based gyroscope) installed on the movement cart (120), and continuously corrects the driving direction or the volumetric rotation of the cart so that the LED panel maintains the rear direction of the accident vehicle even during the rotational movement of the movement cart (120). For example, when the movement cart (120) enters or retreats along a curved path along the outside of the accident vehicle, the rotation angle control algorithm calculates the degree of rotation of the movement cart (120) in real time and controls the LED cell array so that it does not deviate from the rear while the movement cart (120) is moving.

[0124] As such, the configuration of the temporary reflection module (500) according to the present embodiment ensures minimal visibility at the accident site before the reflector module (322) is fully stacked on the outer side of the strip-shaped fixing material (321), and provides an immediate warning to vehicles approaching from both sides and the rear of the accident vehicle. By utilizing the arrangement of the LED cell array, the rearward-facing design, the proximity sensor-based automatic lighting function, and the rearward-facing maintenance control function while moving, visibility is stably maintained even while the moving cart (120) is traveling back and forth.

[0126] Next, the accident site response device for the automated service for consultation guidance and repair processing related to the vehicle accident report may further include a control unit (600) for controlling the driving of the mobile cart (120), the gripping and towing operation of the cartridge ejection unit (400), the lighting pattern control of the LED cell array, and the image acquisition operation of the scan module (121).

[0127] The control unit (600) comprises a driving control means (610) that controls the forward and backward driving and rotation angles of the moving cart (120) so that the cell array of the moving cart (120) always faces the rear of the accident vehicle while the moving cart (120) moves back and forth along the outside of the accident vehicle; a gripping and traction control means (620) that performs left and right movement of the gripping bar (420) of the cartridge unwinding unit (400) for gripping the ends of the wound material of the first cartridge and the second cartridge, an inflow operation of the gripping groove (430), and tension maintenance control for traction of the wound material; and an LED scan synchronization that determines the lighting pattern of the LED cell arrays of the fixed cart (110) and the moving cart (120) and synchronizes the image acquisition time of the scan module (121) in response to the detection signal of the proximity sensor, the shooting timing of the scan module (121), and the unwinding progress state of the cartridge unwinding unit (400), and synchronizes the image acquisition time of the scan module (121). It may include a control means (630).

[0128] With the two fixed carts (110) mounted at the side mirror positions on both sides of the accident vehicle, the temporary reflection module (500) of the fixed cart (110) and the movable cart (120) can be controlled to light up according to the detection signal of the proximity sensor.

[0129] The end of the strip-shaped fixing material (321) exposed from the first cartridge can be controlled to be fed into and gripped in the gripping groove (430) of the cartridge unloading part (400) through the gripping traction control means (620).

[0130] In the starting motion to move the above-mentioned moving cart (120) from one side of the accident vehicle to the other side via the rear, the driving control means (610) can control the forward movement, rotation angle, and approach distance of the moving cart (120) so that the above-mentioned strap-type fixing member (321) is kept in close contact with the outer surface of the accident vehicle.

[0131] After reaching the opposite fixed cart (110), the drawer-type storage means (330) of the second mounting area (312) can be controlled in conjunction with the gripping traction control means (620) so that it is pulled out.

[0132] When the end of the reflector module (322) is exposed in the second cartridge withdrawn above, the end of the reflector module (322) can be controlled to be gripped in the gripping groove (430) through the gripping traction control means (620).

[0133] While the above-mentioned moving cart (120) is being returned to the starting point from the other side of the accident vehicle, the driving control means (610) can be used to maintain a rotation angle so that the moving cart (120) faces the rear of the accident vehicle. The reflector module (322) can be controlled to return along a 'U'-shaped path so that it is Velcro-fastened to the outside of the strip-shaped fixing material (321).

[0134] In all traction processes of the above-mentioned strip-shaped fixing material (321) and reflector module (322), the tension of the wound material is controlled to be maintained within a certain range through the gripping traction control means (620), thereby enabling the entire operation to be controlled in conjunction so that the above-mentioned strip-shaped fixing material (321) and the above-mentioned reflector module (322) are sequentially unwound and stacked along the outside of the accident vehicle.

[0135] The accident scene response device according to the present embodiment includes a control unit (600) capable of integrally performing driving control of a mobile cart (120), gripping and pulling operation of a cartridge unloading unit (400), lighting pattern control of an LED cell array, and image acquisition control of a scan module (121). The control unit (600) is configured to perform all operations of the entire device sequentially and synchronously in conjunction with an automated service for vehicle accident reception and damage analysis, and can be implemented as a microcontroller (MCU)-based control board or an ARM-based SoC-based control board.

[0136] The control board is placed inside the mobile cart (120), and the main processing can be performed based on a 32-bit MCU (e.g., STM32F4, ESP32, NXP series, etc.). Some control functions requiring safety and real-time capabilities can be implemented using an RTOS-based task separation method, and driving control, gripping and traction control, and LED and scan control are operated as independent tasks but share information with each other through a common message bus or CAN and UART communication.

[0137] The driving control means (610) includes a servo motor, BLDC wheel motor, or stepping motor driver for controlling a wheel-based driving unit (710) mounted on the lower part of the moving cart (120). The two wheels of the moving cart (120) are configured to enable individual PWM control, allowing for precise control of the driving direction, curvature, and rotation angle. Additionally, an IMU (6-axis gyroscope + accelerometer) and a wheel encoder are used for driving position estimation, and rotation angle control to maintain a constant rearward direction of the accident vehicle is performed in real time based on the yaw value of the IMU.

[0138] This driving control is used to correct the LED cell array so that it always faces the rear direction of the accident vehicle, even if the moving cart (120) moves in a curved shape along the outer surface of the vehicle. For example, when the moving cart (120) moves forward and moves along the curved surface of the vehicle's fender, the driving control means (610) detects the rotation angle deviation and maintains rearward orientation by adjusting the wheel speed difference.

[0139] The gripping traction control means (620) is composed of a gripping bar (420) of the cartridge unwinding unit (400), an inflow pressurizing actuator, a left and right displacement driving unit on the guide rail (440), and a feedback control circuit including a tension maintaining sensor.

[0140] The gripping bar (420) moves left and right via a small linear actuator or a ball screw-based mini slider, and the inflow into the gripping groove (430) is made by a fine movement in the forward direction in the range of 5 to 15 mm. At this time, when the docking detection sensor detects contact with the fixed cart (110), the gripping bar (420) is pushed forward so that the end of the wound material is naturally inserted into the gripping groove (430).

[0141] After gripping the wound material, traction is linked to wheel driving, and the tension maintenance sensor transmits real-time tension values ​​to the control unit (600) using a load cell-based or tension roller-based sensor. The control unit (600) adjusts the driving speed and gripping traction force so that the tension is maintained within a set value range (e.g., 0.8 to 1.5 kgf).

[0142] The LED / scan synchronization control means synchronizes the lighting time and flashing pattern of the LED cell array with the image acquisition time of the scan module (121). The scan module (121) is composed of an optical camera or a LiDAR / ToF-based sensor and captures the accident site in real time while moving.

[0143] When the proximity sensor detects approach to the side mirror, the LED module lights up, and the scan module (121) first takes 2 to 3 reference images and then starts the main outer shooting sequence. The LED flashing pattern is adjusted so as not to affect the shooting exposure and not to interfere with the scan timing.

[0144] (1) Fixed cart (110) with two mounting and temporary reflective modules (500) lit

[0145] When two fixed carts (110) are attached to the side mirror positions on both sides of the accident vehicle, the proximity sensor of the gripping receiving part (200) detects the presence of the side mirrors. This signal is immediately transmitted to the control unit (600) to light up the LED cell arrays of the fixed carts (110) and the moving carts (120). This ensures visibility of the rear of the accident site even before the reflector module (322) is deployed.

[0146] (2) The end of the strip-shaped fixing material (321) of the first cartridge is gripped.

[0147] The control unit (600) moves the gripping bar (420) of the cartridge ejection unit (400) toward the first mounting area (311), and when the docking detection sensor is activated, advances the gripping bar (420) to feed and fix the end of the strip-shaped fixing material (321) into the gripping groove (430).

[0148] (3) Move cart (120) from one side of the accident vehicle → rear → other side

[0149] The moving cart (120) moves forward by means of a driving control means (610) and moves along the outer side of the accident vehicle. During this process, tension maintenance control is continuously maintained so that the strip-shaped fixing material (321) adheres to the surface of the vehicle. The rotation angle is adjusted in real time according to the curvature of the vehicle, so that the strip-shaped fixing material (321) is stably deployed along the outer edge of the vehicle.

[0150] (4) Pull out the drawer-type storage means (330) of the second mounting area (312)

[0151] When the moving cart (120) reaches the opposite fixed cart (110), the control unit (600) controls the drawer-type storage means (330) to be withdrawn. After the locking latch is released, the withdrawal tray protrudes outward in an automatic or semi-automatic manner, and the end of the reflector module (322) of the second cartridge is exposed.

[0152] (5) Hold the reflector module (322) of the second cartridge

[0153] The gripping bar (420) is moved toward the second mounting area (312) to insert the end of the reflector module (322) into the gripping groove (430) and secure it.

[0154] (6) The 'C' path of the moving cart (120)

[0155] During the return process, the moving cart (120) moves along a 'U'-shaped path while maintaining a rearward orientation so that the reflector module (322) is securely attached to the outer edge of the strip-shaped fixing material (321) with Velcro. During this process, the tension is controlled so that it does not become excessive or loose.

[0156] (7) Tension stabilization of the entire traction operation and completion of final lamination

[0157] The tension-maintaining control means continues to operate until the stacking of the reflector module (322) is completed, and finally, the strip-shaped fixing material (321) and the reflector module (322) form a continuous, complete outer protection structure along the outer perimeter of the accident vehicle.

[0158] The accident scene response device of the present invention can be utilized as a core module of a comprehensive service that automatically links to accident reporting, consultation guidance, damage analysis, and repair processing stages immediately after a vehicle accident occurs. When an accident occurs, automatic accident detection is performed through the user's vehicle's telematics system or an insurance company app, and the accident scene response device is initially deployed by mounting a fixed cart (110) near both side mirrors of the accident vehicle. As soon as the proximity sensor of the fixed cart (110) detects the entry of the side mirror, the temporary reflection module (500) of the fixed cart (110) and the movable cart (120) is illuminated, ensuring clear visibility from the rear of the accident vehicle even in nighttime and adverse weather conditions. This initial illumination operation provides a function to immediately notify both the vehicle driver and subsequent vehicles of the accident situation.

[0159] Afterward, the moving cart (120) grasps the end of the strip-shaped fixing material (321) from the first cartridge and unwinds it along the outer surface of the vehicle while moving back and forth between the fixed cart (110). The scan module (121) mounted on the moving cart (120) continuously acquires image and distance information along the outer surface of the accident vehicle during this movement process. The scan module (121) may be configured in a combined form of an RGB camera and a distance measuring sensor, and secures raw data for analyzing external damage such as dents, scratches, cracks, and damage to parts of the vehicle. The LED-scan synchronization control means adjusts the lighting timing of the LED cell so as not to be affected by changes in external illumination, thereby ensuring stable, high-quality shooting.

[0160] The scan data acquired in this way is first processed in the control unit (600) inside the mobile cart (120) and then transmitted to a mobile device or server. On the server, a deep learning-based damage analysis system automatically operates to classify the damaged area, estimate the type and extent of the damage, and determine the type of accident (frontal collision, side contact, rear collision, etc.). The analysis results are generated in the form of an “automatic accident damage report” and are automatically entered into the insurance company’s accident reporting system. The driver checks the draft of the accident description through the app and completes the report immediately by performing simple corrections if necessary. In this process, there is no need for a counselor to ask about the accident situation one by one, and the driver does not need to repeat the explanation for a long time while in an agitated state.

[0161] The mobile cart (120) arriving at the opposite fixed cart (110) automatically grasps the end of the reflector module (322) in the second mounting area (312) from which the drawer-type storage means (330) is drawn out. Subsequently, while the mobile cart (120) performs a return motion, the reflector module (322) is sequentially attached to the outer surface of the strip-type fixing material (321) using a Velcro method. Because the second cartridge is positioned to protrude outward, the reflector module (322) forms a wider projection width at the rear, which significantly improves visibility around the accident vehicle, especially at night or in high-speed driving environments. Finally, the vehicle is surrounded by the reflector module (322), significantly reducing the possibility of a secondary accident.

[0162] Simultaneously with the installation of these reflectors, the server transmits information to a network of repair shops affiliated with the insurance company based on the damage analysis results. The repair shops can automatically calculate the estimated repair costs and whether parts need to be replaced, and customers can compare the repair times, costs, and distances of various repair shops presented in the app and make a reservation immediately. If necessary, tow truck coordination is also automatically performed. In addition, for accident investigation and future dispute response, the deployment time of the reflector module (322), the time of scanning, and the device operation logs are recorded in the system for all work processes.

[0163] The service flow described in this embodiment is an example where the mechanical components and control system of the present invention are naturally combined, and can be utilized to automate the entire process from accident detection and safety assurance to damage analysis, insurance claim submission, and repair scheduling. This significantly reduces the operational burden on the driver and improves safety at the accident scene, accident processing speed, and data accuracy.

[0164] In this embodiment, the structural relationship between the safety cart (100), fixed cart (110), mobile cart (120), and cartridge winding unit (300) constituting the accident site response device according to the present invention is explained more clearly. In the present invention, the safety cart (100) is the highest concept forming the entire device system and refers collectively to components that are positioned around the outer perimeter of the accident vehicle and perform a series of operations to deploy a strip-shaped fixing material (321) and a reflector module (322). The safety cart (100) is composed of two fixed carts (110) that are independently installed near the side mirrors on both sides of the accident vehicle, and a mobile cart (120) that travels between the two fixed carts (110) and tows and deploys the strip-shaped fixing material (321) and the reflector module (322).

[0165] The fixed cart (110) is a device that is fixedly placed at a designated location on the accident vehicle and includes a main body platform (700) in the shape of a square column and a gripping receiving portion (200) provided on the front thereof. The main body platform (700) is designed to stand adjacent to the outside of the accident vehicle, and a gripping receiving portion (200) with a recessed structure is formed on its side so that a side mirror can be inserted. The fixed cart (110) does not have a movement function and serves as a position reference point responsible for mechanical connection with the accident vehicle. A first mounting area (311) and a second mounting area (312) are formed on the rear or side of the fixed cart (110), configured to receive a first cartridge and a second cartridge, respectively, in which a strip-shaped fixing material (321) and a reflector module (322) are wound, in a horizontal position. Additionally, the fixed cart (110) is equipped with an LED cell array and a proximity sensor so that it can also perform a temporary reflection function.

[0166] Unlike the fixed cart (110), the mobile cart (120) has an actual moving function and moves back and forth between the fixed carts (110) to tow and deploy the strip-shaped fixing material (321) and the reflector module (322). The mobile cart (120) is composed of a main body platform (700) with a wheel-based driving unit (710) positioned at the bottom, a scan module (121) facing the direction of the accident vehicle, an LED cell array on the top of the main body platform (700), and a cartridge unwinding unit (400) positioned at the rear of the main body platform (700). The mobile cart (120) does not carry the cartridge itself, but operates by approaching and grasping the ends of the first cartridge and the second cartridge housed on the side of the fixed cart (110). According to this structural relationship, the fixed cart (110) performs the role of physically mounting the cartridge, and the mobile cart (120) performs the operation of grasping and towing the wound material from the mounted cartridge.

[0167] The cartridge winding section (300) is composed of a first cartridge, a second cartridge, and a first mounting area (311) and a second mounting area (312) that accommodate them. The cartridge winding section (300) is arranged in a form mechanically coupled to the fixed cart (110), but the cartridge itself is not directly transported by the movable cart (120); instead, the movable cart (120) interacts by approaching and gripping the end. Thus, the fixed cart (110) functions as a position reference point and a cartridge storage location, while the movable cart (120) performs a dynamic role of receiving the winding material from this cartridge and unfolding it. Through a docking operation in which the rear surface of the movable cart (120) contacts the gripping receiving section (200) of the fixed cart (110), the gripping bar (420) of the cartridge unwinding section (400) secures a mechanical alignment state in which it can accurately grip the end of the winding material.

[0168] As such, in the structural hierarchy of this embodiment, the safety cart (100) is the highest concept, and below it, two fixed carts (110) and one mobile cart (120) exist as separate and independent devices. The fixed cart (110) functions as a device that grips the side mirror and is coupled to the vehicle, while the mobile cart (120) functions as a device that tows the strip-type fixing material (321) and the reflector module (322) while driving. Although the cartridge winding unit (300) is positioned on the fixed cart (110), it has a cooperative structure in which the actual winding and towing operations are performed by the mobile cart (120). According to this design method, the present invention is configured so that each component can be manufactured separately and maintained independently, yet the entire system operates organically as a single device at an actual accident site.

[0169] In this embodiment, more specific mechanical configurations and operating principles regarding the gripping receiving portion (200), flip-type gripping portion (220), and elastic hinge (230) structure of the fixed cart (110) are described. The gripping receiving portion (200) is a structure designed to stably grip the lower part of the side mirror of the accident vehicle when it is inserted into the fixed cart (110), and includes mechanical characteristics that consider deformability and restoring force to accommodate a variety of side mirror shapes.

[0170] In this embodiment, the gripping receiving portion (200) is formed as a recessed groove structure on the front or side of the fixed cart (110) main body platform (700), and the opening is opened to face the direction of vehicle movement. The width and depth of the gripping space (210) are suitable for a width of 60 to 120 mm and a depth of 40 to 80 mm based on the dimensions of the lower part of the side mirror of a typical passenger car or SUV, and the internal cross-section can be manufactured in a trapezoidal or curved mixed shape. This structure ensures that the side mirror receives a certain level of guidance force when inserted and induces it to automatically align to the center even if the direction of entry is slightly off.

[0171] A flip-type gripping part (220) is positioned at the entrance of the gripping space (210). The flip-type gripping part (220) is configured such that two thin flaps are attached to the left and right walls, respectively, and each flap can rotate outward or forward by the force of the side mirror entering. The flip-type gripping part (220) is suitable for polyurethane (PU), rubber-based synthetic resin, or TPE (thermoplastic elastomer) material with a thickness of 1.5 to 3 mm. The height of the flap is set in the range of 30 to 70 mm and serves to support the lower part of the side mirror by wrapping the entrance of the gripping space (210) with appropriate strength.

[0172] The rotation of the flip-type gripping part (220) is achieved by an elastic hinge (230). The elastic hinge (230) is a high-elasticity connecting part integrally molded on the bottom or side of the flip-type gripping part (220), and provides a restoring force by utilizing the elastic deformation of the material itself without using a separate metal hinge. It is desirable that the thickness of the hinge part be designed to be thin, such as 0.8 to 1.5 mm, so that rotation is natural and does not break even with repeated operation. The elastic hinge (230) may be manufactured as an integral structure with the entire flip-type gripping part (220), or it may be attached to the gripping receiving part (200) by ultrasonic welding or clip fastening after separate molding. This structure allows the side mirror to open naturally without excessive impact when inserted, and after insertion is complete, it performs the function of pressing the side mirror into the gripping space (210) and fixing it by means of the restoring force.

[0173] When the side mirror enters the gripping receiving portion (200), the flip-type gripping portion (220) can rotate outward by about 20 to 40 degrees, and when the side mirror reaches the final position, the elastic hinge (230) is restored so that the gripping portion closes again at a narrow angle. At this time, the end of the flip-type gripping portion (220) lightly presses the outer lower part of the side mirror, thereby keeping the fixed cart (110) in close contact with the vehicle without shaking. A thin rubber pad may be attached to the bottom surface of the gripping receiving portion (200) for anti-slip treatment, which serves to reduce unnecessary friction or vibration between the vehicle and the fixed cart (110) while driving.

[0174] In this embodiment, the flip-type gripping part (220) may be designed to automatically adjust the gap between the two flaps to about 5 to 8 mm so as to accommodate various types of side mirrors. This is implemented by a fine elastic pad provided on the inner side wall of the gripping space (210) deforming according to the width of the side mirror and adjusting the rotation range of the flip-type gripping part (220). In addition, the front edge of the gripping part is formed as an insertion-guiding curved surface so that the side mirror can enter without obstruction when inserted, thereby maximizing usability.

[0175] After the fixed cart (110) is fixed to the vehicle, the gripping receiving portion (200) and the flip-type gripping portion (220) provide reference points for the entire device. Since the moving cart (120) can perform gripping alignment of the wound material by docking its rear end to the platform surface of the fixed cart (110), the structural stability of the gripping receiving portion (200) directly affects the alignment precision of the entire system. Therefore, in this embodiment, durable materials are used so that the gripping receiving portion (200) and the flip-type gripping portion (220) do not deform even under repeated use and impact environments, and a curved design is applied to minimize stress concentration in the rotating parts, thereby ensuring long-term usability.

[0176] In this embodiment, a V-shaped guide surface formed inside the cartridge unwinding section (400), a gripping bar (420), a gripping groove (430), and a series of mechanical mechanisms that allow the end of the wound material to naturally and stably flow into the gripping groove (430) are described in detail. These components play a key role in the entire process from the moment the moving cart (120) docks with the fixed cart (110) to stably grasping the end of the wound material and performing traction after gripping.

[0177] In this embodiment, an elastic moving space (410) extending in the left and right directions is provided inside the cartridge unwinding section (400), and a V-shaped guide surface is formed in front of this space to guide the end of the wound material. The V-shaped guide surface consists of two branched guide surfaces, one branching toward the first cartridge and the other toward the second cartridge. Each guide surface can be made of a metal molded plate or a high-rigidity plastic panel, and a coating (e.g., PTFE coating) is applied to the surface to minimize friction so that the end of the wound material slides down without getting caught even if it comes into contact.

[0178] The angle of the V-shaped guide surface can be set in the range of 40 to 70 degrees to naturally guide the end of the winding material into the central joining point, and the joining point between the branch guide surfaces is designed to be precisely connected to the central alignment line where the gripping bar (420) is located. This structure provides an inflow performance in which the end of the winding material is automatically guided to the center even if the moving cart (120) is not accurately docked to the fixed cart (110) or there is a slight left-right deviation.

[0179] The gripping bar (420) is formed vertically at the foremost point where the V-shaped guide surface joins, and the gripping groove (430) is a narrow groove structure formed longitudinally on the front or side of the gripping bar (420). The width of the gripping groove (430) is set to a range of 5 to 10 mm and the depth to a range of 3 to 8 mm, and a fine elastic pad or rubber coating may be applied inside so that the material of the end of the wound material (the sheet material of the strip-shaped fixing material (321) or the reflector module (322)) can be naturally fitted and fixed inside the groove. This rubber coating ensures that the end of the wound material is stably fixed without slipping inside the groove, and the grip is maintained even with vibrations or shocks occurring during driving.

[0180] The process of the end of the wound material entering the gripping groove (430) proceeds as follows. When the moving cart (120) is docked to the rear of the fixed cart (110), the docking detection sensor detects this and transmits a signal to the control unit (600). The control unit (600) operates the inflow pressure actuator to move the gripping bar (420) forward by 3 to 10 mm, and this displacement provides an initial pressure that causes the end of the wound material to automatically be fitted into the gripping groove (430) as it travels down along the V-shaped guide surface. At the moment of docking, the end of the wound material enters the alignment position of the gripping groove (430) through gravity, elastic reaction force, or the inductive force of the branching guide surface, and as the gripping bar (420) advances, the end is securely fixed inside the groove.

[0181] During this process, the left end detection sensor and the right end detection sensor determine which end of the winding material, either the first cartridge or the second cartridge, is exposed, and instruct the gripping bar (420) to move in the corresponding direction. For example, if only the end of the first cartridge is exposed, the gripping bar (420) waits for docking while moving slightly to the left within the selected movement space, and after docking, the end of the winding material flows into the center along the first branch guide surface and is accurately coupled to the gripping groove (430). On the other hand, if the second cartridge is withdrawn, the extended movement space is activated so that the gripping bar (420) can move over a wider range, and at this time, the gripping bar (420) performs end inflow while moved to the right in alignment with the outer protruding position of the second cartridge.

[0182] In this embodiment, by optimizing the joining angle of the V-shaped guide surface, the insertion depth of the gripping groove (430), the amount of forward displacement, and the hardness of the rubber coating, the problem of the end of the wound material twisting or being folded in two layers when entering can be prevented. In particular, the surface curvature of the branching guide surface is designed to guide the end to proceed without step, and in some sections, a fine curve or a gentle groove can be formed to improve the stability of the end's entry.

[0183] In addition, in this embodiment, even if rotation or twisting occurs at the end of the wound material during the inflow process, the sides of the gripping groove (430) are designed to physically correct it. This is because the upper and lower ends of the groove have a bent structure, so if the end enters in a twisted state, the part that entered first is corrected inside the groove, and the entire end can be fixed in an aligned state. This structure provides consistent gripping stability even in an environment where the moving cart (120) may have various postures or angles during operation.

[0184] In this embodiment, the structure and function of the elastic movement space (410) provided inside the rear of the moving cart (120) are described in more detail. The elastic movement space (410) of the present invention is a key component for enabling the gripping bar (420) to accurately access the respective positions even if the ends of the wound material of the first cartridge and the second cartridge are exposed at different positions. The elastic movement space (410) consists of a selective movement space that operates in a narrow area and an expanded movement space that expands when the drawer-type storage means (330) is pulled out.

[0185] The selective movement space is formed within a left-right width limiting structure inside the main body platform (700) of the moving cart (120), and is used in a normal state where both the first cartridge and the second cartridge are located inside the platform. The left-right width of the selective movement space is set to approximately 15 to 30 mm, and the gripping bar (420) moves smoothly within this range along the guide rail (440). Since the structure of this area is based on the premise that the windings of the two cartridges are aligned near the rear of the moving cart (120), the gripping bar (420) maintains a state where it can be aligned with the end by moving only slightly to the left or right. The guide rail (440) of the selective movement space is formed in a straight shape, and the rail surface is finished with metal or wear-resistant synthetic resin to minimize wear even when the gripping bar (420) moves repeatedly.

[0186] The extended movement space is activated when the drawer-type storage means (330) is pulled out. When the second cartridge protrudes outward from the main body platform (700), the gripping bar (420) needs to access a position that extends outward beyond the range of the existing selection movement space. To this end, the extended movement space is formed in a structure that continues continuously outward from the selection movement space. The width of the extended movement space is secured at a level of 40 to 70 mm, and this is designed to align with the amount of the second cartridge pulled out. A guide rail (440) continuous with the selection movement space is installed in the extended movement space, and the rail is fixed to the rear structure of the main body platform (700) through an L-shaped or T-shaped support frame. This support frame structure ensures that the extended movement space stably maintains the shape of protruding outward from the main body platform (700).

[0187] The guide rail (440) of the expansion movement space can be implemented in two ways. The first method is an integrated rail structure in which the rail of the selection movement space extends outward from the rear of the main body platform (700), in which case the entire rail is manufactured as a single continuous metal molded part to minimize the step difference at the rail connection point. The second method is to install independent rails in the selection movement space and the expansion movement space, respectively, and connect the connection points of both rails with a fine curvature or slope. This structure is advantageous for the outer rail to independently secure the operable range of the expansion movement space when the drawer-type storage means (330) is pulled out.

[0188] The drawer-type storage means (330) and the extended movement space are linked, and the extended movement space is automatically activated according to the position of the withdrawal tray. The amount of movement of the withdrawal tray is transmitted to the control unit (600) via a position sensor or magnetic switch attached to the sliding rail, and the control unit (600) can instruct the gripping bar (420) to move to the center reference line of the extended movement space or to fine-tune it within the extended movement space based on the signal. When the second cartridge is fully withdrawn, the gripping bar (420) enters a standby state in the extended movement space rather than the selected movement space, and in this state, the gripping groove (430) is aligned with the outer protruding position of the end of the reflector module (322).

[0189] An auxiliary roller or sliding block is installed at the bottom of the rail support frame so that no rotation or shaking occurs while the gripping bar (420) moves left and right in the extended movement space. This structure prevents the support force from decreasing when the gripping bar (420) moves outward and increases the horizontal rigidity of the entire rail to ensure stable gripping operation.

[0190] In this embodiment, the cartridge winding unit (300) is configured to perform an accurate gripping operation even when the end positions of the first cartridge and the second cartridge are completely different from each other by distinguishing between a selective movement space and an extended movement space. The selective movement space provides stable gripping induction performance within a fixed internal structure, and the extended movement space is directly linked to the withdrawal amount of the drawer-type storage means (330) to enable gripping over a wide range. This configuration provides a technical basis for the device of the present invention to consistently grip all ends of the wound material even under various vehicle models, various side mirror positions, and various cartridge placement conditions.

[0191] In this embodiment, the 'C'-shaped return path driving performed by the moving cart (120) to stably stack the reflector module (322) held by the opposite fixed cart (110) on the outer side of the strip-shaped fixing material (321) is geometrically described. The moving cart (120) does not simply return in a straight line, but moves along a trajectory that enters the rear side of the accident vehicle once and then changes direction to proceed toward the other front side of the accident vehicle. This 'C'-shaped driving pattern has the purpose of providing an optimal relative position for the reflector module (322) to be attached to the outer side of the strip-shaped fixing material (321) with strong adhesive force, while ensuring that the moving cart (120) moves safely without deviating from the outer side of the vehicle.

[0192] When the moving cart (120) reaches the opposite fixed cart (110), the rotation angle is first set so as to face the rear of the vehicle. At this time, the axis of the moving cart (120) is positioned to have a rotation angle of approximately 70 to 110 degrees from the side of the vehicle to the rear, which serves to induce the reflector module (322) to form a curvature that matches the trajectory of the strip-shaped fixing material (321) as the cart approaches the rear. Since the rear bumper and trunk line of the vehicle generally have a certain level of curvature, the moving cart (120) naturally enters by drawing a gentle curve through differential driving control based on speed difference during the stage of approaching the rear center. This section constitutes the first curve of the 'U'-shaped path.

[0193] When the moving cart (120) reaches the center of the rear of the vehicle or an area close thereto, the control unit (600) sets a straight section while maintaining the rotation angle of the moving cart (120). This straight section allows the cart to pass completely through the rear area, providing a minimum rear clearance distance that allows it to proceed stably without interference with the retreating vehicle or surrounding obstacles. The straight distance can be set in the range of 300 to 600 mm depending on the vehicle size and the applied model, and during this straight movement, the reflector module (322) is guided to be naturally attached along a position that aligns with the rear side of the strip-shaped fixing material (321).

[0194] After passing the straight section, the moving cart (120) rotates again toward the side of the vehicle and begins to move toward the opposite front side. The rotation at this time forms a second curved section extending from the rear to the front, and in this section, the moving cart (120) adjusts the difference in speed between the left and right wheels along the lateral curvature of the vehicle so that the reflector module (322) is attached along the same curvature as the curved surface of the vehicle. This second curved section is important to minimize the geometric gap between the side of the vehicle and the connection part of the strip-shaped fixing material (321) to which the reflector is to be attached, and during this curved driving process, the module naturally aligns with the outer contact surface of the fixing material.

[0195] Afterward, the moving cart (120) moves toward the front of the vehicle and travels along a straight path toward the side fixed cart (110) from which it originally started, and this straight section constitutes the last vertical stem of the 'U'-shaped path. In this section, the reflector module (322) is stably pressed and attached to the outer side of the strip-shaped fixing material (321), and the tension maintenance control means operates during driving so that the reflector module (322) does not detach and is regularly stacked. The moving cart (120) stably maintains rearward orientation through rotation angle control based on the IMU and wheel encoder throughout the entire path and performs the attachment operation without interference with the LED module.

[0196] In summary, the 'U'-shaped path of the moving cart (120) consists of a first curved section that moves along the curvature of the rear of the vehicle, a rear straight section, a second curved section leading to the front side, and a final straight section, and these two curved sections provide the geometric elements essential for stably stacking the reflector module (322) along the outer shape of the vehicle. This driving method ensures uniform attachment quality that is difficult to achieve with simple straight or rotational movement alone, and is configured to naturally follow the rear curvature and side curvature that are common to all vehicle models.

[0197] In this embodiment, based on the accident scene response device of the present invention, the entire automated service flow extending from the accident reporting stage to consultation guidance, damage analysis, and repair reservation is described in detail. This service flow includes not only the mechanical configuration and control functions of the device itself, but also software algorithms operating around the device, server integration, and a data exchange structure with insurance company and repair shop networks. The entire system aims to minimize the burden of operation on the user immediately after a vehicle accident occurs, ensure safety at the accident scene, and collect damage information quickly and accurately.

[0198] When an accident occurs to a vehicle, the accident event is first automatically transmitted to a server by the collision detection function of a telematics device or an insurance company application. The server collects accident-related data, such as GPS location, vehicle speed, and sudden deceleration patterns, and then issues a dispatch order to a support vehicle equipped with the accident scene response device of the present invention among nearby service networks. Upon arrival, the support personnel attach a fixed cart (110) to the bottom of both side mirrors of the accident vehicle and then dock a mobile cart (120) at the starting point on the front of the main body platform (700). When the side mirror enters the gripping space (210), a proximity sensor detects this, and the temporary reflection module (500) is immediately lit to ensure visibility of the rear of the accident vehicle.

[0199] When the fixed cart (110) is installed, the mobile cart (120) grasps the end of the strip-shaped fixing material (321) of the first cartridge according to the command of the control unit (600) and begins to move along the side of the accident vehicle. During this process, the scan module (121) continuously photographs the damaged area on the outer side of the vehicle, and image data and distance data are recorded together. The captured data is initially aligned and corrected inside the mobile cart (120) and then transmitted to the server in real time. The server executes a vehicle exterior damage analysis algorithm based on the received image data and automatically classifies the location of dents, paint peeling, scratches, and damage to specific panels. In this analysis process, a pre-trained deep learning model is utilized, and the model determines the accident type and damage type as multiple classes to automatically generate an accident summary.

[0200] When the moving cart (120) reaches the opposite fixed cart (110), the drawer-type storage means (330) of the second mounting area (312) is withdrawn by the control unit (600), and the end of the reflector module (322) of the second cartridge is exposed. The end of the reflector module (322) is automatically fed into the gripping groove (430) of the cartridge ejection unit (400) and pulled. Afterward, the moving cart (120) returns along a 'U'-shaped path and sequentially attaches the reflector module (322) to the outer side of the strip-type fixing material (321). This attachment process is combined with driving control and tension maintenance control to ensure uniformity, and finally, the accident vehicle is protected by the entire outer perimeter with reflectors. As a result, the possibility of a secondary accident is significantly reduced, and safety around the vehicle is restored.

[0201] While the reflector is being attached, the server automatically generates a damage report based on real-time analyzed damage information. The report consists of damage location, size, and classification categories, and calculates the estimated repair difficulty and the need for parts based on vehicle model, year, and color information. This report is linked to the insurance company's accident reporting system to automatically generate an accident number, completing the accident reporting process without the need for agent intervention. Drivers can review the generated draft accident description via the mobile app and make simple modifications if necessary.

[0202] The insurance company's server transmits analyzed damage information in real-time to a network of affiliated repair shops. The repair shops automatically generate estimated quotes and return service availability information, including repair timelines, parts stock availability, and the number of waiting vehicles. Users can compare quotes and available times from multiple shops via a mobile app and make an immediate reservation; if necessary, a tow truck call is also automatically integrated. If a rental car service is required, a linked feature that recommends a suitable vehicle based on the damaged area and repair duration may also be included.

[0203] In addition, all device operation information performed at the accident site is recorded as a service log. The time of mounting the fixed cart (110), the start and end times of deploying the reflector module (322), the scanning stage, the tension maintenance control record, and the driving record of the mobile cart (120) are stored along with timestamps to provide objective accident processing data in the event of a future dispute. These logs can be used as reference materials by insurance companies, repair shops, and accident investigation agencies, and can also be used as auxiliary materials for determining the circumstances of the accident and calculating the fault ratio.

[0204] The service flow according to the present embodiment is optimized for automating a series of procedures from accident detection to reflector deployment, safety assurance, damage analysis, insurance claim, and maintenance reservation. By combining the mechanical device and software system of the present invention, it has the effect of significantly reducing time delays, information omissions, and human error that occurred in the existing accident processing process. Furthermore, it can function as a comprehensive accident response platform that minimizes the psychological anxiety and burden of the driver immediately after an accident and significantly reduces the risk of secondary accidents around the accident vehicle.
