Description

A new energy vehicle safety monitoring and prevention device Technical Field

[0001] This invention relates to the field of new energy vehicle testing, specifically to a new energy vehicle safety monitoring and prevention device. Background Technology

[0002] To ensure the safety of new energy vehicles after they are launched on the market, crash tests are often required during the research and development and / or testing phases. While spontaneous combustion may not occur immediately after a crash test, it can develop some time later due to factors such as the compression of the vehicle and battery. Therefore, it is necessary to monitor and observe the post-collision condition of the vehicles separately. Previously, the method involved either placing the tested vehicles in an open area or in a separate, enclosed space, waiting for an alarm to sound before personnel arrived to extinguish the fire. However, this time lag could be significant, potentially leading to inaccurate data on the location and extent of the fire due to excessive burning, and there was also a risk of the fire spreading. Therefore, developing an automated system capable of monitoring and automatically extinguishing fires is essential. Summary of the Invention

[0003] The purpose of this invention is to solve the above-mentioned problems by proposing a safety monitoring and prevention device for new energy vehicles.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A safety monitoring device for new energy vehicles includes a frame, a water tank, a vehicle platform, monitoring components, a lifting assembly, and a controller for receiving and processing information collected by the monitoring components. The vehicle platform is movably mounted on the frame via the lifting assembly. The water tank is located within the frame and below the vehicle platform. The monitoring components and the lifting assembly are electrically connected to the controller. The monitoring components include at least a plurality of temperature sensors mounted on the frame for activating the lifting assembly to immerse the vehicle in the water tank when a temperature exceeding the specified limit is detected.

[0006] Preferably, the monitoring component also includes several industrial temperature sensors detachably arranged around the monitored vehicle, wherein the temperature sensors on the frame are infrared temperature sensors with their probes facing the center of the vehicle platform.

[0007] Preferably, the lifting assembly includes at least a lifting motor located at the top of the frame, a chain driven by the lifting motor for lifting the vehicle platform, and a guide rail assembly for guiding and limiting the vehicle platform. The guide rail assembly includes a guide rail disposed on the inner wall of the pool and a guide wheel disposed on the vehicle platform and cooperating with the guide rail.

[0008] Preferably, the frame is equipped with a lifting motor, the motor shaft of which is arranged across the top of the frame, and the two ends of the motor shaft are provided with sprockets for connection with the chain drive. Sprockets are provided at the four corners of the top of the frame, and two sprockets on the same side are connected by chain drive.

[0009] Preferably, the chain includes a ring-shaped driven chain and a traction chain with two free ends. The lower end of the traction chain is connected to the vehicle platform, and the upper end passes around the corresponding sprocket and connects to the corresponding driven chain.

[0010] Preferably, the sprocket connecting the motor shaft is a double sprocket that connects a driven chain and a traction chain respectively, with a single sprocket fitted onto the far end of the driven chain away from the double sprocket.

[0011] Preferably, the traction chain fitted with the double sprocket is connected laterally to the upper half of the driven chain, and the traction chain near the single sprocket is connected from the bottom to the lower half of the corresponding driven chain.

[0012] Preferably, the frame is equipped with electric safety hooks for limiting the vehicle platform at at least four corners, controlled by a controller. When an abnormal vehicle temperature is detected, the controller controls the electric safety hooks to detach from the vehicle platform, and the lifting assembly is activated.

An oxygen concentration sensor is also provided on the vehicle platform, and a liquid level sensor is also provided in the water tank. A video monitor is also provided on the frame. The oxygen concentration sensor, liquid level sensor, and video monitor are electrically connected to the controller, and the controller is also connected to an audible and / or visual alarm.

[0014] Preferably, a maintenance and cleaning platform is provided at the top of the pool corresponding to one end of the vehicle platform, and a ladder is provided outside the pool corresponding to the maintenance and cleaning platform.

[0015] Beneficial effects:

[0016] 1. This application uses multiple temperature sensors at various locations on the vehicle platform to sense the temperature at multiple points. When the temperature at a certain location exceeds a preset temperature as detected by the temperature sensor, the controller receives the signal and immediately issues an audible and / or visual alarm. It can also notify relevant personnel via SMS, WeChat, or other means. Simultaneously, the controller quickly lowers the vehicle platform into a water tank for fire extinguishing. Because of the multiple temperature sensor locations, any abnormality in the location of one or more temperature sensors can trigger the alarm and fire extinguishing mechanism.

[0023] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below. The present invention will be further described below with reference to the accompanying drawings.

[0024] Example 1:

[0025] A safety monitoring device for new energy vehicles includes a frame 1, a water tank 2, a vehicle platform 3, monitoring components, a lifting assembly, and a controller for receiving and processing information collected by the monitoring components. The vehicle platform is movably mounted on the frame via the lifting assembly. The water tank is located within the frame and below the vehicle platform. The monitoring components and the lifting assembly are electrically connected to the controller. The monitoring components include at least a plurality of temperature sensors 4 mounted on the frame, used to activate the lifting assembly to immerse the vehicle in the water tank when a temperature exceeding the specified limit is detected. The controller is also connected to an audible and / or visual alarm.

[0026] This application uses multiple temperature sensors at various locations on the vehicle platform to sense the temperature at multiple points. When the temperature at a certain location exceeds a preset temperature as detected by the temperature sensor, the controller receives the signal and immediately issues an audible and / or visual alarm. It can also notify relevant personnel via SMS, WeChat, or other means. Simultaneously, the controller quickly lowers the vehicle platform into a water tank for fire extinguishing. Because of the multiple temperature sensor locations, any abnormality in one or more sensor locations can trigger the alarm and fire extinguishing mechanism. Furthermore, monitoring temperature anomalies using multiple sensors allows the controller to accurately record which area of ​​the vehicle first heats up and ignites, thus providing valuable data for future improvements.

[0027] If smoke is used to monitor fire, the smoke will diffuse and its path of ascent depends on obstacles. Therefore, smoke alarms cannot provide effective data on the ignition point. Furthermore, rapid smoke alarm activation may only provide data on a single fire location after the fire is extinguished, while other locations that may spontaneously combust after a delay or slight warming may remain undetected, leading to the limited data from a single test. In contrast, the testing and monitoring method proposed in this application can continuously monitor the temperature rise data of various areas of the vehicle at multiple points, providing a more comprehensive understanding of vehicle spontaneous combustion and offering convenient and powerful data for future research and improvement.

[0028] In addition, the water tank and vehicle platform of this application are detachably installed in the frame, so the installation is not limited by the water tank or area. It can be installed wherever there is enough space. It is also convenient to disassemble and move. It does not require digging a separate sedimentation tank in a fixed location as a water tank. It is low in cost, easy to operate, and has a wide range of applications.

[0029] Example 2:

[0030] The difference from the above embodiments lies in that the monitoring component also includes several industrial temperature sensors, i.e., thermocouples, detachably arranged around the monitored vehicle. The temperature sensors mounted on the frame are infrared temperature sensors with their probes facing the center of the vehicle platform. Some of the temperature sensors, through infrared monitoring, can continue to measure even after the vehicle spontaneously combusts, thus accurately recording temperature changes throughout the entire process. Other temperature sensors are thermocouples that can be directly installed on the vehicle body, interior, or under the vehicle, enabling immediate detection of temperature changes, resulting in more comprehensive and accurate temperature monitoring data, and timely triggering of early warnings.

[0031] Example 3:

[0032] The difference from the above embodiments is that the lifting assembly includes at least a lifting motor 51 located at the top of the frame, a chain 53 driven by the lifting motor for lifting the vehicle platform, and a guide rail assembly for guiding and limiting the vehicle platform. The guide rail assembly includes a guide rail 61 disposed on the inner wall of the pool and a guide wheel 62 disposed on the vehicle platform and cooperating with the guide rail.

[0033] Traditional hoisting methods that use wire ropes to pull steel cables may lead to uneven lifting at different points after long-term use due to uneven force or the stretching of the wire rope. In the case of multi-point lifting platforms, the platform is prone to tilting and requires frequent correction.

[0034] This application utilizes a chain drive system to precisely and smoothly raise and lower the vehicle platform, minimizing deviations, ensuring stable movement, and reducing the failure rate. The guide rail assembly in this application also effectively maintains the stability of the vehicle platform during raising and lowering, preventing swaying and improving the safety of the equipment during use.

[0035] Example 4:

[0036] The difference from the above embodiment lies in that a lifting motor is provided on the frame, and the motor shaft 511 of the lifting motor is arranged across the top of the frame. Both ends of the motor shaft are provided with sprockets 52 for connection with the chain drive. Sprockets are provided at the four corners of the top of the frame, and two sprockets on the same side are connected by a chain drive. This application achieves synchronous lifting of four points on the frame to four corresponding points on the vehicle platform through the cooperation of a single motor, chain, and sprockets. It has fewer components, better synchronization, and a simpler structure.

[0037] The chain includes a ring-shaped driven chain 531 and a traction chain 532 with two free ends. The lower end of the traction chain is connected to the vehicle platform, and the upper end passes over a corresponding sprocket and connects to the corresponding driven chain. In this application, the traction chain used for lifting the vehicle platform is directly connected at its upper end to the driven chain, thus avoiding the need for counterweights or chain winding structures. This simplifies the structure while ensuring efficient lifting of the traction chain. The sprocket connecting the motor shaft is a double sprocket that connects one driven chain and one traction chain respectively. A single sprocket is fitted onto the far end of the driven chain away from the double sprocket.

[0038] The traction chain, fitted with a double sprocket, is laterally connected to the upper half of the driven chain, while the traction chain near the single sprocket is connected from the bottom to the lower half of the corresponding driven chain. This structure allows for a streamlined design while cleverly achieving precise and synchronous lifting of the traction chains at the four corners of the vehicle platform. It is also less prone to failure and has low equipment cost.

[0039] Example 5:

[0040] The difference from the above embodiment is that the frame is equipped with electric safety hooks 7, controlled by a controller, at least at the four corners corresponding to the vehicle platform. When an abnormal vehicle temperature is detected, the controller controls the electric safety hooks to detach from the vehicle platform, and the lifting assembly is activated. The electric safety hooks ensure that the vehicle platform remains safely and stably horizontally positioned during normal monitoring, with minimal or no tension on the lifting motor. The lifting motor can then remain inactive, resulting in low energy consumption and safety. This also effectively prevents accidental descent in case of motor failure and facilitates the disassembly and maintenance of the lifting motor.

[0041] Example 6:

[0042] The difference from the above embodiment is that there are at least 8 temperature sensors, that is, at least 8 infrared temperature sensors. At least two temperature sensors are evenly distributed on each of the four top beams of the frame. Of course, more temperature sensors can be installed on the longer beams. An oxygen concentration sensor is also provided on the vehicle platform, a liquid level sensor is also provided in the water tank, and a video monitor is also provided on the frame. The oxygen concentration sensor, liquid level sensor and video monitor are electrically connected to the controller, so that the status of the equipment can be accurately grasped, which facilitates daily monitoring and equipment maintenance.

[0043] Example 7:

[0044] The difference from the above embodiment is that a maintenance and cleaning platform 21 is provided at the top of the pool corresponding to one end of the vehicle platform, and a ladder 22 is provided outside the pool corresponding to the maintenance and cleaning platform. The upper and lower parts of the pool are respectively provided with a water inlet 23 and a drain outlet 24.

[0045] The water tank has inlet and outlet ports, with the outlet having two drainage directions to treat clean water for vehicles that have not been submerged and wastewater for vehicles that have been submerged, respectively. Additionally, personnel can access the maintenance and cleaning platform via escalator to disassemble, adjust, or clean vehicles or equipment on the frame.

[0046] During operation, the test vehicle is first placed onto the platform using a forklift, with the vehicle positioned as centrally as possible. After placement, the mounting brackets for the multiple infrared temperature sensors on the frame are adjusted to the desired testing points on the vehicle. The vehicle is then moved onto the platform via a ladder, and thermocouples are installed. Afterward, personnel evacuate, and the system enters monitoring mode.

[0047] When the infrared temperature sensor detects a point that exceeds the upper limit, the system will trigger an alarm, activate the audible and visual alarm lights, sound a siren, open the four electric safety hooks on the vehicle platform, start the lifting motor, and lower the vehicle platform into the water pool for fire extinguishing.

[0048] This application uses multiple temperature sensors at various locations on the vehicle platform to sense the temperature at multiple points. When the temperature at a certain location exceeds a preset temperature as detected by the temperature sensor, the controller receives the signal and immediately issues an audible and / or visual alarm. It can also notify relevant personnel via SMS, WeChat, or other means. Simultaneously, the controller quickly lowers the vehicle platform into a water tank for fire extinguishing. Because of the multiple temperature sensor locations, any abnormality in one or more sensor locations can trigger the alarm and fire extinguishing mechanism. Furthermore, monitoring temperature anomalies using multiple sensors allows the controller to accurately record which area of ​​the vehicle first heats up and ignites, thus providing valuable data for future improvements.
