Description

Technical Field

[0001] This utility model relates to the field of intelligent transportation, specifically to intelligent warning signs. Background Technology

[0002] With the continuous development of intelligent vehicles and road safety technologies, vehicle warning signs are playing an increasingly important role in improving road safety. Traditional vehicle warning signs typically consist of a triangular reflective symbol and are widely used when a vehicle breaks down or is involved in an accident, placed behind the vehicle to warn passing vehicles to take evasive action. However, while traditional warning signs have a certain warning effect, they also have certain problems in terms of convenience, stability, and storage security.

[0003] Firstly, existing warning signs typically rely on manual placement, a process that is not only cumbersome but also poses certain safety hazards. When a vehicle breaks down or is involved in an accident, the driver needs to get out and place the warning sign behind the vehicle to alert other drivers. However, in inclement weather, heavy traffic, or emergency situations, drivers may face significant safety risks when performing this action, and it is difficult to guarantee that the warning sign will be placed in the appropriate position in a timely and accurate manner.

[0004] Secondly, existing warning signs are usually made of fixed, rigid materials, making them bulky, difficult to store, and inconvenient to carry. Storing them inside a vehicle often takes up considerable space, and they are easily damaged by external pressure or impacts during storage. Especially given the limited space in modern vehicles and the high demands of car owners for storage, the existing design of warning signs no longer meets people's needs for convenience and safety.

[0005] Therefore, the design of existing warning signs has failed to fully consider the needs for convenience, rapid deployment, and storage security. Utility Model Content

[0020] The present invention will be further described in detail below with reference to the accompanying drawings.

[0021] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive element, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.

[0022] This embodiment relates to an intelligent warning sign, as shown in the following figure. Figure 1 The intelligent warning sign includes a supporting body 110, a control drive module 120 on the top of the supporting body 110, and an environmental sensing module 130 around the supporting body 110. The reflective assembly 200 includes at least a first reflective element 210. The two ends of the first reflective element 210 are rotatably mounted on the top of the supporting body 110 via a rotatable connecting assembly 230. By controlling the rotation of the first reflective element 210, the first reflective element 210 can be in a retracted or unfolded posture. The movable component 300 is located at the bottom of the supporting body 110, and the control drive module 120 is electrically connected to the environmental sensing module 130 and the movable component 300 respectively. The control drive module 120 receives environmental sensing data collected by the environmental sensing module 130 and controls the movable component 300 to move according to the environmental sensing data, so as to drive the supporting body 110 to move towards the preset warning position, and move the reflective component 200 to the preset warning position.

[0023] The supporting body 110 refers to the base supporting the overall structure, which can be implemented using a lightweight metal frame or a frame made of polymer materials, without specific limitations. The supporting body 110 is used to integrate various functional modules. The reflective component 200 refers to a device with light reflection function. The first reflective element 210 can specifically be implemented as a folding reflector with a rotating shaft. The moving component 300 refers to the component that drives the supporting body 110 to move, and can at least be implemented as a wheel set with a drive motor. The control drive module 120 refers to a module with functions such as data processing, command generation, and power output, and can specifically be composed of components such as a battery, a power drive board, and a signal control board. The environmental perception module 130 refers to an information acquisition device, which can specifically be implemented using a combination of sensors such as a lidar sensor, a camera, and an infrared photoelectric sensor, used to acquire obstacle distance and road environment data. The rotating connection component 230 refers to a mechanical structure that realizes the rotational movement of the reflector. Specifically, it can be a metal rotating shaft with a bushing, achieving rotational freedom through a hole-shaft fit, or it can be a motor with an output shaft, realizing the rotational movement of the reflector through the output shaft of the motor.

[0024] Specifically, when a vehicle malfunctions, the driver and passengers only need to quickly release the intelligent warning sign near the vehicle and immediately evacuate the scene to avoid danger. The environmental perception module 130 scans the surrounding road environment in real time to obtain data on vehicle position, obstacle distribution, and safe area. After analyzing the data, the control and drive module 120 generates path planning instructions, driving the moving component 300 to move the supporting body 110 along a predetermined route to the safe warning position. During this process, the first reflector 210 unfolds into a triangular warning posture according to the instructions via the rotating connecting component 230, and folds up when needed. The entire system achieves autonomous switching from storage state to working state through electromechanical coordination. Alternatively, the driver and passengers can manually move the first reflector 210 to unfold it into a triangular warning posture before releasing the intelligent warning sign.

[0025] Preferably, refer to Figure 1 The top of the supporting body 110 is also provided with a fixed bracket 220, and the top of the fixed bracket 220 is provided with a mounting hole. The two ends of the first reflector 210 are rotatably connected to the mounting hole through the rotating connection assembly 230.

[0026] The fixed bracket 220 refers to the rigid structure used to support the reflective component 200. Specifically, it can be made of metal frame or high-strength plastic and fixed to the top of the bearing body 110 by bolts or welding. Alternatively, it can be integrally formed with the bearing body 110 and can disperse the mechanical stress when the reflective component 200 rotates.

[0027] The mounting hole refers to the through hole structure set on the top of the fixed bracket 220. Specifically, it can be a circular hole with a diameter that can be adapted to the shaft diameter of the rotating connection component 230. It is used to accommodate the insertion of the rotating connection component 230 and limit its displacement range.

[0028] Among them, the rotating connection component 230 refers to the mechanical connection component that realizes the rotational motion. Specifically, it can adopt a combination structure of a rotating shaft and a bearing. The two ends of the rotating shaft are inserted into the mounting holes respectively, and the bearing is sleeved on the outer surface of the rotating shaft to reduce frictional resistance.

[0029] Specifically, the fixed bracket 220 provides a stable fulcrum for the first reflector 210 through the mounting hole. When the rotating shaft of the rotating connecting assembly 230 passes through the mounting hole and connects to both ends of the first reflector 210, the first reflector 210 can rotate around the axis of rotation. During the movement of the supporting body 110, the rigid support of the fixed bracket 220 can prevent the connection from loosening due to vibration or impact. At the same time, the cooperation between the mounting hole and the rotating connecting assembly 230 can precisely control the rotation angle of the first reflector 210, so that it maintains the preset warning angle when unfolded and fits tightly against the surface of the supporting body 110 when retracted.

[0030] Preferably, refer to Figure 1 , Figure 2 as well as Figure 3 The fixed bracket 220 includes a first fixed frame 221 and a second fixed frame 222, which are respectively disposed at opposite ends of the top of the supporting body 110; the rotating connection assembly 230 includes a first connector 231 and a second connector 232; the reflective assembly 200 also includes a first reflective strip 213, the first reflective element 210 is composed of a second reflective strip 211 and a third reflective strip 212, the opposite ends of the first reflective strip 213 are respectively provided with a first connecting hole 2131 and a second connecting hole 2132, and one end of the second reflective strip 211 and the third reflective strip 212 is respectively provided with a third connecting hole 2111 and a fourth connecting hole 2121; the first connecting... The first reflector 213 is sequentially inserted through the first connecting hole 2131, the third connecting hole 2111, and the mounting hole of the first fixing frame 221, so that the first reflector 213 and the second reflector 211 are relatively fixed; the second connector 232 is sequentially inserted through the second connecting hole 2132, the fourth connecting hole 2121, and the mounting hole of the second fixing frame 222, so that the first reflector 213 and the third reflector 212 are relatively fixed; through the cooperation of the first connector 231 and the second connector 232, the first reflector 213, the second reflector 211, and the third reflector 212 are fixed to the top of the supporting body 110 in a retracted or unfolded posture.

[0031] The connecting hole refers to a through hole used for assembling rotating parts. It can be processed by precision stamping and achieves relative rotation through clearance fit. The first reflective strip 213, the second reflective strip 211, and the third reflective strip 212 can refer to strip-shaped components with reflective function. Specifically, they can be made of polycarbonate substrate with reflective film laminated on the surface.

[0032] Specifically, the first fixing frame 221 and the second fixing frame 222 are respectively installed on both sides of the top of the supporting body 110, forming a stable support base. The first reflective strip 213 is arranged laterally between the two fixing brackets 220, and the connecting holes at both ends of the first reflective strip 213 correspond to the connecting holes of the second reflective strip 211 and the third reflective strip 212, respectively. The first connector 231 passes through the mounting hole of the first fixing frame 221 and connects the left end of the first reflective strip 213 to the second reflective strip 211; the second connector 232 passes through the mounting hole of the second fixing frame 222 and connects the right end of the first reflective strip 213 to the third reflective strip 212. When the warning sign needs to be unfolded, the second reflective strip 211 and the third reflective strip 212 can be rotated and unfolded around the axis of the connector, forming a stable triangular structure with the first reflective strip 213; when it needs to be stored, the second reflective strip 211 and the third reflective strip 212 can be folded and attached to the surface of the first reflective strip 213.

[0033] Preferably, refer to Figure 1 , Figure 2 as well as Figure 3 The first connecting member 231 includes a first fixing seat 2312 and a first motor 2311, and a second connecting member 232 includes a second fixing seat 2322 and a second motor 2321. The first fixing seat 2312 and the second fixing seat 2322 are disposed at opposite ends of the top of the supporting body 110, and the tops of the first fixing seat 2312 and the second fixing seat 2322 are respectively provided with mounting slots for mounting the corresponding motors. The output shaft of the first motor 2311 passes through the first connecting hole 2131, the third connecting hole 2111 and the mounting hole of the first fixing bracket 221 in sequence, wherein the first connecting hole 2131 and the mounting hole of the first fixing bracket 221 are connected to the output shaft. For rotational engagement, the third connecting hole 2111 is fixedly connected to the output shaft; the output shaft of the second motor 2321 passes sequentially through the mounting holes of the second connecting hole 2132, the fourth connecting hole 2121, and the second fixing bracket 222, wherein the second connecting hole 2132 and the mounting holes of the second fixing bracket 222 are rotationally engaged with the output shaft, and the fourth connecting hole 2121 is fixedly connected to the output shaft; the first motor 2311 and the second motor 2321 are respectively used to drive the second reflective strip 211 and the third reflective strip 212 to rotate relative to the first reflective strip 213, so that the reflective assembly 200 is in a retracted or extended posture on the top of the supporting body 110.

[0034] The first fixed base 2312 refers to the support structure used to fix the first motor 2311. Specifically, it can be implemented by using a metal or plastic base with a mounting groove, and its function is to provide a stable mounting base for the motor.

[0035] The first motor 2311 refers to the power device that drives the second reflector 211 to rotate. Specifically, it can be implemented using a stepper motor or a servo motor, and torque transmission is achieved through a fixed connection between the output shaft and the third connecting hole 2111. The second motor 2321 refers to the power device that drives the third reflector 212 to rotate. Specifically, it can be implemented using a stepper motor or a servo motor, and torque transmission is achieved through a fixed connection between the output shaft and the fourth connecting hole 2121.

[0036] Rotational fit refers to a connection method that allows relative rotation between the output shaft and the first connecting hole 2131 and the mounting hole, which can be achieved using a bearing or bushing structure. Fixed connection refers to a connection method where there is no relative rotation between the output shaft and the third connecting hole 2111, which can be achieved using a keyway fit or interference fit to ensure that the motor power is effectively transmitted to the reflector strip.

[0037] Specifically, when the reflective assembly 200 needs to be deployed, the first motor 2311 and the second motor 2321 start simultaneously, and the output shaft drives the second reflective strip 211 and the third reflective strip 212 to rotate around the first reflective strip 213. Since the third connecting hole 2111 and the fourth connecting hole 2121 are fixedly connected to the output shaft, the reflective strips rotate synchronously with the motor output shaft, while the first connecting hole 2131 and the second connecting hole 2132 are rotately engaged with the output shaft, keeping the first reflective strip 213 relatively stationary. When the reflective strip rotates to a preset angle, the motor stops operating, and the reflective assembly 200 forms a stable deployed posture. When retracting, the motor rotates in the opposite direction, and the reflective strip folds to the top of the supporting body 110, reducing the space occupied.

[0038] Preferably, refer to Figure 4 The moving component 300 includes a drive wheel set 310, which is rotatably mounted on the bottom of the support body 110.

[0039] The drive wheel assembly 310 refers to a wheel structure driven by a drive motor, specifically a combination of rubber tires, which enables the autonomous movement of the load-bearing body 110 via electric drive. Rotatable mounting means that the drive wheel assembly 310 is connected to the load-bearing body 110 via a shaft or bearing structure, specifically using a flange and rolling bearings, allowing the drive wheel assembly 310 to rotate around a fixed axis to adjust its direction of travel.

[0040] Specifically, the drive wheel assembly 310 is positioned at the bottom of the support body 110, and its speed and direction are adjusted by the electrical signal output by the control drive module 120. When the environmental perception module 130 detects a preset warning position, the control drive module 120 sends a movement command to the drive wheel assembly 310, which then moves the support body 110 along the ground to the target area. During this process, the rotational motion of the drive wheel assembly 310 is transmitted to the support body 110 through a bearing structure, ensuring smooth movement and controllable direction.

[0041] Preferably, refer to Figure 4 The moving component 300 also includes a connecting arm 320; one end of the connecting arm 320 is hinged to the bottom of the supporting body 110, and the other end is connected to the drive wheel assembly 310; the connecting arm 320 can rotate around its hinge point 321 with the bottom of the supporting body 110 to drive the drive wheel assembly 310 from the retracted state to the working state, or from the working state to the retracted state.

[0042] The connecting arm 320 refers to a swingable structural component used to support and adjust the position of the drive wheel assembly 310. Specifically, it can be made of metal rods or engineering plastic components and is rotatably connected to the load-bearing body 110 through a pivot or pin.

[0043] Specifically, the connecting arm 320 can be manually pushed to rotate around the hinge point 321, or it can be driven by a drive device to rotate around the junction point.

[0044] Preferably, refer to Figure 4 The moving component 300 also includes a connecting rod structure 330 and a telescopic motor 340. The two ends of the connecting rod structure 330 are respectively hinged to the middle of the connecting arms 320 on both sides. The telescopic motor 340 is located in the middle of the connecting rod structure 330. The telescopic motor 340 is used to drive the connecting rod structure 330 to extend and retract axially, so as to drive the connecting arms 320 to rotate synchronously around the hinge point 321 at the bottom of the bearing body 110, so as to realize the drive wheel set 310 from the retracted state to the working state, or from the working state to the retracted state.

[0045] The telescopic motor 340 refers to a drive device capable of outputting linear motion, which can be implemented using a linear motor or a hydraulic cylinder. The extension and retraction of the connecting rod structure 330 is adjusted by controlling the stroke length of the telescopic motor 340. The hinged connection refers to a connection method that allows components to rotate around a fixed axis, which can be implemented using a pin-bearing structure to ensure the stability of the connecting arm 320 during rotation.

[0046] Specifically, when the smart warning sign needs to be moved to a preset warning position, the telescopic motor 340 drives the linkage structure 330 to extend axially, causing the connecting arms 320 on both sides to rotate outward synchronously around their hinge point 321 with the bottom of the supporting body 110. This causes the drive wheel set 310 to unfold from a retracted state to a working state, providing stable support for the movement of the supporting body 110. When the warning task is completed or storage is required, the telescopic motor 340 drives the linkage structure 330 to retract, causing the connecting arms 320 to rotate in the opposite direction, causing the drive wheel set 310 to retract to a state close to the bottom of the supporting body 110, reducing space occupation.

[0047] Preferably, refer to Figure 3 The control drive module 120 includes a power output submodule 121, a signal control submodule 123, and a power control submodule 122. The power output submodule 121 is used to provide power output for the intelligent warning sign. The power control submodule 122 is used to regulate the voltage and distribute the power output by the power output submodule 121, and provide a stable power supply for the signal control submodule 123 and the moving component 300. The signal control submodule 123 is used to receive the sensing data collected by the environmental sensing module 130 and generate corresponding control commands.

[0048] The power output submodule 121 is a device that provides basic electrical energy to the system, which can be implemented using a rechargeable lithium battery pack or a fuel cell. Its function is to provide continuous energy support for the movement, sensing, and control functions of the warning sign. The power control submodule 122 is a circuit unit that converts and distributes electrical energy, which can be implemented using an integrated voltage regulator and power distribution chip. Its function is to convert the raw electrical energy from the power output submodule 121 into different voltage levels and dynamically distribute it to each power-consuming unit to ensure stable system operation. The signal control submodule 123 is the core unit for data processing and command generation, which can be implemented using an embedded microcontroller combined with a communication interface circuit. Its function is to analyze the real-time data from the environmental sensing module 130 and generate movement control commands to enable the warning sign to move autonomously.

[0049] Specifically, the power output submodule 121 forms a power transmission link with the signal control submodule 123 through the power control submodule 122. The power control submodule 122 has a built-in multi-channel voltage regulator circuit, for example, converting the 12V output of the lithium battery pack to 5V for use by the signal control submodule 123, while simultaneously distributing 24V high voltage to the drive motor of the moving component 300. The signal control submodule 123 receives road images, obstacle distances, and infrared heat source data collected by the environmental perception module 130 via the CAN bus, and generates steering and speed control commands for the moving component 300 after data processing, driving the carrier body 110 to move towards the preset warning position.

[0050] Preferably, refer to Figure 1 as well as Figure 2 The environmental perception module 130 includes an image acquisition submodule 131, an infrared perception submodule 132, and a distance perception submodule 133. The environmental perception data includes image data, infrared perception data, and distance perception data. The image acquisition submodule 131 is used to acquire image data; the infrared perception submodule 132 is used to acquire infrared perception data; and the distance perception submodule 133 is used to acquire distance perception data.

[0051] The image acquisition submodule 131 is a device that acquires visual information about the surrounding environment through optical equipment, specifically a camera or image sensor, used to capture real-time images of the environment surrounding the warning sign. The infrared sensing submodule 132 is a device that detects target objects by receiving infrared radiation, specifically an infrared sensor or thermal imager, used to detect living or heating objects in the environment. The distance sensing submodule 133 is a device that measures the distance between the target object and the warning sign, specifically an ultrasonic sensor or lidar, used to monitor the distance between the warning sign and obstacles in real time.

[0052] Specifically, when the intelligent warning sign needs to be moved to a preset warning position, the image acquisition submodule 131 continuously acquires image data of the surrounding environment, such as identifying road edges, vehicle or pedestrian positions; the infrared sensing submodule 132 simultaneously detects whether there are human or animal people in the environment to avoid collisions during the movement of the warning sign; the distance sensing submodule 133 measures the distance between the warning sign and obstacles in real time, such as determining whether there are stationary objects blocking the path. The control drive module 120 comprehensively processes the three types of sensing data to generate movement path planning instructions, driving the moving component 300 to adjust the direction or speed of movement to ensure that the warning sign accurately reaches the target position.

[0053] In some specific implementations, the image acquisition submodule 131 may be a wide-angle camera with night vision capability, the infrared sensing submodule 132 may be an array-type infrared detector, and the distance sensing submodule 133 may be configured as a multi-directional laser rangefinder. The control and drive module 120 establishes a three-dimensional environment model by fusing the three types of sensing data and dynamically corrects the movement trajectory.

[0054] Understandably, traditional warning signs rely solely on manual observation of the environment and cannot acquire multi-dimensional sensing data. This application, however, integrates image, infrared, and distance sensing functions to achieve comprehensive monitoring of complex environments. In existing technologies, single sensors are susceptible to interference from light, temperature, or obstacles. This solution, through complementary multi-source data, significantly improves the reliability and accuracy of environmental perception.

[0055] Preferably, the intelligent warning sign also includes a display module (not shown), which is used to display the current status and current control mode of the intelligent warning sign.

[0056] The display module refers to a device that can present visual information. Specifically, it can be implemented using an LED display screen or an LCD screen. By receiving the electrical signals output by the control drive module 120, it converts the working status of the device into visual content.

[0057] The current status refers to the real-time operating condition of the intelligent warning sign during operation. This can be identified through the position signal of the moving component 300 or the unfolding angle signal of the reflective component 200, such as its moving state, unfolded or retracted state, operating speed, battery level, and fault indicator light information. The current control mode refers to the driving logic for the intelligent warning sign's actions, which can be switched through the data processing results of the environmental perception module 130 or user-preset commands, such as automatic obstacle avoidance mode, manual remote control mode, or emergency braking mode.

[0058] Specifically, the display module and the control drive module 120 are connected via a signal line. When the environmental perception module 130 collects external environmental data, the control drive module 120 generates control commands according to a preset algorithm and synchronously updates the content of the display module. For example, when the moving component 300 drives the supporting body 110 to move towards a preset warning position, the display module displays the movement progress and direction in real time; when the reflective component 200 is in an unfolded posture, the display module indicates the unfolding completion status through icons or text. Furthermore, users can determine whether to switch control modes by observing the content of the display module. For example, when encountering complex road conditions in automatic mode, users can switch to manual mode. At this time, the display module synchronously updates the mode indicator to provide operation feedback.

[0059] It should be noted that the display module can be deployed in any location on the smart warning sign, such as around, on top, at the bottom, or on the reflective components or drive wheel assembly of the supporting body. The specific location can be set according to actual needs, and there are no restrictions here.

[0060] The above is only used to illustrate the technical solution of this utility model and not to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
