Abstract

The invention discloses a self-unfolding type warning sign system and a vehicle. The system comprises a containing device, a triggering mechanism and a warning mark body. The triggering mechanism responds to a signal of a vehicle safety control system, generates thrust to push the warning mark body out of the containing device by a preset distance and drives the warning mark body to be unfolded. The warning mark body is automatically connected with an internal circuit through mechanical movement of the warning mark body in the unfolding process. The system may include an environment awareness module to evaluate deployment conditions. According to the scheme, automatic deployment of the warning mark is realized.

Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicle safety devices, in particular to a warning sign system capable of being automatically deployed when a vehicle is in an emergency and a control method. BACKGROUND

[0002] When a vehicle breaks down or has an accident on the road (such as a highway), the driver needs to manually place a triangular warning sign. This process has safety risks and takes a long time to operate manually. There are some concepts of warning signs that can be automatically deployed in the prior art, but most of them still require manual intervention or lack the ability to judge the safety of the deployment environment after being triggered. SUMMARY

[0003] I. Invention Purpose The present application provides a self-expanding warning sign system and a vehicle, aiming to solve the problem of low efficiency and lack of environmental perception ability in the prior art.

[0004] II. Technical Solution To achieve the above purpose, the present application adopts the following technical solution: A self-expanding warning sign system, comprising a containing device, a triggering mechanism and a warning sign body. The containing device is fixed to the vehicle body and is used to store the device in an untriggered state; the triggering mechanism is arranged in the containing device and is in communication connection with the vehicle safety control system; the warning sign body is in a compressed or folded state in the storage state, and is internally provided with an energy source and an electrical equipment; The triggering mechanism is configured to act in response to a trigger signal from the vehicle safety control system to generate an initial thrust; the initial thrust is used to push the warning sign body out of the containing device to a predetermined distance and drive the warning sign body from the compressed or folded state to the expanded working state; the warning sign body is configured to automatically establish an electrical connection between the energy source and the electrical equipment through the mechanical movement generated during the shape change process; The system can also include an environmental perception module for obtaining environmental information behind the vehicle; the vehicle safety control system is configured to determine whether the ejection safety condition is met based on the information of the environmental perception module, and to control the issuance of the trigger signal accordingly; The present application provides three preferred embodiments: Inflatable: the triggering mechanism is a mechanical elastic mechanism, and the warning sign body is an inflatable structure. The thrust part first triggers the inflation of the compressed gas source, and then pushes the sign out; Built-in spring type: the trigger mechanism is a gas driving mechanism, and the warning sign body is a mechanical spring type structure. After the high-pressure gas pushes the sign out, the internal supporting spring expands and unfolds. Folding plate type: the trigger mechanism is an electromagnetic ejection device, and the warning sign body is a folding plate type structure. After the electromagnetic force ejects the sign, the internal spring pushes the supporting frame to unfold.

[0005] III. Advantages The advantages of the present application are: 1. Full automation and safety: full process automation from sensing to deployment is realized, and the risk of personnel getting off the vehicle is completely avoided; 2. Fast and efficient: the deployment process is completed within a few seconds, much faster than manual operation; 3. Action linkage: power is automatically completed through mechanical movement, achieving the effect of "unfolding and working"; 4. Environmental decision: by integrating the environmental sensing module, the system has the ability to judge the safety of the deployment time, preventing secondary risks that may be caused by hasty ejection of the sign when there is a close vehicle behind; 5. Multi-level warning system: a collaborative protection scheme combining vehicle self-warning and remote sign warning is formed; 6. Multiple implementation methods: three high-reliability implementation schemes of pneumatic, mechanical spring and electromagnetic ejection are provided; 7. Structure optimization: multiple actions are completed by using a single power source, and the structure is compact and reliable. BRIEF DESCRIPTION OF DRAWINGS

[0015] The following is described in conjunction with the drawings Example one (inflatable type): Referring to Figure 2 , Figure 3 , the inflatable warning sign (200) is folded in the containing device (300). The compression spring of the elastic mechanism (100) is locked by the locking mechanism (102). After the vehicle safety system sends a trigger signal, the locking mechanism (102) is unlocked, and the spring pushes the thrust component (101) forward. The thrust component (101) hits the striker device (203), pierces the compressed gas bottle (201), and the gas fills the airbag to make it expand. Then, the thrust component (101) pushes the sign (200) out of the containing device. The airbag expands to pull out the blocking piece (205), which connects the circuit of the battery (204) and starts the related electrical equipment.

[0016] Example two (spring built-in type): Referring to Figure 4 , Figure 5 , the spring type warning sign (600) is placed in the containing device (500). The trigger signal activates the high-pressure gas generator (403), which generates high-pressure gas to push the thrust component (401) to push the sign (600) out. After the sign is pushed out, the internal support spring (602) expands and expands. The air inlet / outlet hole (605) is used to adjust the expansion speed. The expansion movement drives the blocking piece (604) to pull out, which connects the circuit of the battery (603) and starts the related electrical equipment.

[0017] Example three (folding plate type): Referring to Figure 6 , Figure 7The folded plate type warning sign (800) is placed in the containing device (702). The trigger signal makes the electromagnetic generator (701) energized to generate a magnetic field, which interacts with the permanent magnet (801) to pop out the sign (800). After the sign is popped out, the compression spring (802) pushes the folded support frame (803) to expand. The expansion movement drives the blocking piece (805) to pull out, connecting the battery (804) circuit to start the relevant electrical equipment.

[0018] Security optimization embodiment: In an optimized scheme of the present application, the system integrates environmental perception and decision-making module. When the vehicle safety control system (such as ECU) determines that an emergency occurs, the following operations are immediately synchronized: 1. Activate the vehicle level warning: control the vehicle danger warning light (double flash) to work in fast flash or other more conspicuous mode, realize immediate, close-range warning; 2. Start environmental safety assessment: at the same time, instruct the environmental perception and decision-making module to assess the safety conditions of the ejection path based on the vehicle perception system (such as rear radar) in real time If the module determines that the rear environment is safe (i.e. meets the preset safety conditions), the control unit will immediately trigger the ejection of the self-expanding warning sign to establish a long-range, three-dimensional secondary warning area If the module determines that there is a vehicle approaching quickly in the rear (i.e. does not meet the safety conditions), the control unit will suppress the ejection action, but the level one warning (double flash fast flash) will continue to work. The system continues to monitor the environment, and when the danger is removed, it will automatically execute the delayed ejection This scheme ensures that effective warning can be started in the first time in any situation, and through decision-making, the warning sign is deployed at a safe time to form a coordinated multi-level security protection system.

[0019] The above embodiments are only preferred implementation ways of the present application, and those skilled in the art can make various modifications and improvements without departing from the core concept of the present application. These modifications and improvements shall fall within the protection scope of the present application.
