Description

Technical Field

[0001] This utility model relates to the field of fire early warning technology, and in particular to a multi-connected intelligent vehicle fire hazard early warning device. Background Technology

[0002] Electric vehicles, as a clean energy mode of transportation, are rapidly gaining popularity worldwide due to their advantages such as energy efficiency, environmental friendliness, and ease of operation. They primarily operate by using batteries to drive electric motors, replacing traditional internal combustion engine systems. In recent years, with advancements in battery technology, drive control, and intelligent management systems, the range and safety of electric vehicles have significantly improved, making them a crucial direction for future transportation.

[0003] When underground parking lots have poor ventilation and inadequate fire control (such as carelessly discarded cigarette butts), or when charging stations have hidden dangers such as poor grounding or aging wiring, they are highly susceptible to thermal runaway. Especially during charging, the battery system is under high load and is more vulnerable to external heat sources. Since these triggers are mostly external factors, existing vehicle warning systems, which primarily rely on monitoring the internal state of the battery pack, struggle to receive timely external danger signals, resulting in delayed or ineffective warnings. Utility Model Content

[0004] The technical problem this invention aims to solve is that automobiles have insufficient perception capabilities and untimely early warning responses in response to externally induced fire risks.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a multi-connected intelligent vehicle fire hazard early warning device, including a frame, a slot is opened in the center of the frame, and a seat is slidably connected in the slot. The seat has an inner cavity that runs through and connects both sides. An air extraction core is fixedly connected to one side of the seat. A smoke sensor is fixedly connected to the output end of the air extraction core. The smoke sensor and the air extraction core are electrically connected to a control chip. A spring is fixedly connected to the top of the seat. A plug-in post is fixedly connected to the other end of the spring. The plug-in post passes through the side plate of one side of the seat and is tightly plugged into the frame. The top of the frame has several plug-in holes that match the plug-in post.

[0006] As a further improvement of this utility model, the frame is configured as a rod-shaped structure, and both ends are rotatably connected to connecting plates via rotating shafts. A rotating motor is fixedly connected to one side of the connecting plate, and the output end of the rotating motor passes through the connecting plate on one side and is fixedly connected to one end of the rotating shaft.

[0007] As a further improvement of this utility model, multiple screw holes are provided on the bottom sides of both connecting plates, and a horizontal plate is fastened to them by bolts. A dustproof mesh is inserted into the top of the horizontal plate between the two connecting plates.

[0008] As a further improvement of this utility model, a guide plate is fixedly provided at the bottom of the side plate, and a guide groove matching the guide plate is provided at the bottom of the frame.

[0009] As a further improvement of this utility model, dustproof nets are glued to the connecting ports on both sides of the inner cavity.

[0010] As a further improvement of this utility model, a threaded hole groove is provided through one end of the connecting plate, and a bolt is fastened inside the threaded hole groove.

[0011] The beneficial effects of this utility model are as follows: By deploying sensing terminals in high-risk external areas (such as near pillars, side walls, or charging piles), active detection of environmental fire-inducing factors is achieved, greatly improving the coverage and proactive response of the early warning system. The rotating motor, in conjunction with the connecting plate and frame, forms a three-dimensional adjustment mechanism, allowing the base to achieve precise angular positioning within a spatial range. The cooperative structure of the base, guide plates, and guide grooves ensures stable sliding and accurate positioning, while also facilitating recycling or replacement maintenance. The horizontal plate and dustproof mesh constitute a closed protection system, protecting the base from dust and damage when not in operation, extending equipment lifespan, and adapting to complex outdoor or garage environments. The modular design of the entire unit facilitates rapid on-site disassembly, repositioning, and deployment. Attached Figure Description

It should be understood that the embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0020] This utility model provides a multi-connected intelligent vehicle fire hazard early warning device, including a frame 1;

[0021] As attached Figure 1 , 2 As shown in Figure 3, a slot is provided in the center of the frame 1, and a base 2 is slidably connected within the slot. An inner cavity is provided inside the base 2, connecting both sides. Dust screens 11 are glued to the connecting openings on both sides of the inner cavity to prevent impurities from being sucked into the inner cavity by the suction core. A suction core, preferably a DC 11.1V suction core, is fixedly connected to one side of the base 2. A smoke sensor, preferably an MQ-2 smoke sensor, is fixedly connected to the output end of the suction core. Both the smoke sensor and the suction core are electrically connected to a control chip, which is an STM32 microcontroller. The STM32 microcontroller can be remotely monitored via a mobile phone through a Wi-Fi module.

[0022] As attached Figure 1 , 3 As shown, to ensure reliable locking, a spring 3 is fixedly connected to the top of the seat 2, and a plug post 4 is fixedly connected to the other end of the spring 3. The plug post 4 passes through the side plate on one side of the seat and is tightly plugged into the frame 1. Several plug holes 5 matching the plug post 4 are opened on the top of the frame 1.

[0023] As attached Figure 2 , 3As shown in Figure 4, the frame 1 is configured as a rod-shaped structure, with connecting plates 6 rotatably connected to both ends via rotating shafts. One end of the connecting plate 6 has a threaded slot 12, with bolts securely fastened inside; this is used for assembling and installing the device. A rotating motor 7 is fixedly connected to one side of the connecting plate 6. The output end of the rotating motor 7 passes through one side of the connecting plate 6 and is fixedly connected to one end of the rotating shaft. The connecting plate 6 on the other side is rotatably connected to the frame 1 on the other side via a rotating shaft. The frame 1, located between the rotating shafts of the two connecting plates 6, can rotate freely under the drive of the rotating motor 7 to adjust the direction of the seat 2 on the frame 1. Multiple screw holes are provided on the bottom sides of both connecting plates 6, and a horizontal plate 8 is fastened to them via bolts. A dustproof mesh 9 is inserted into the top of the horizontal plate 8, located between the two connecting plates 6. When not in operation, the seat 2 can be rotated to the inside of the two connecting plates 6, and the assembly of the horizontal plate 8, bolts, and dustproof mesh 9 provides protection during non-operational periods. A guide plate 10 is fixedly installed at the bottom of the side plate, and a guide groove matching the guide plate 10 is opened at the bottom of the frame 1; it is used to assist the seat 2 in guiding and sliding between the frames 1.

[0024] Working Principle: In practical implementation, the device is securely installed to the on-site support or wall structure via the screw holes at the bottom of the connecting plate 6. After the rotating motor 7 is started, it drives the connected rotating shaft to rotate through the output shaft, causing the frame 1 to rotate as a whole, thereby driving the seat 2 to complete the direction adjustment. It can accurately align with dangerous areas that are difficult to observe, such as corners or the backs of columns in underground parking lots. Pulling the plug-in post 4 upward causes the spring 3 to deform, and the plug-in post 4 moves out of the plug-in hole 5. With the cooperation of the guide plate 10 and the guide groove inside the frame 1, the seat 2 can maintain its smooth sliding without deviation. Releasing the spring 3 again allows the plug-in post 4 to be inserted into the plug-in hole 5 at the top of the frame 1, achieving a stable lock on the seat 2. The air extraction core located inside the seat 2 starts working, actively drawing in air from the aligned area. The air enters the inner cavity after being filtered by the dust screens 11 on both sides, and the smoke concentration is detected by the connected MQ-2 smoke sensor. The detection signal is transmitted to the STM32 control chip in real time for judgment. When the concentration exceeds the threshold, the control chip immediately transmits the data to the mobile phone via the Wi-Fi module, outputting a fire warning signal to the user. In non-operational mode, the motor can be rotated in reverse to turn the base 2 into the protective area formed by the frame 1 and the connecting plate 6. A dustproof net 9 is installed on the top of the horizontal plate 8 to achieve structural compaction and protection, preventing damage to core components from external dust or physical impact, thereby ensuring safe standby and long-term durability of the equipment.
