Technical Field

[0001] This invention relates to the field of automotive safety equipment technology, and in particular to a vehicle fire extinguisher fixing system, a method of use, and a vehicle. Background Technology

[0002] With economic and technological development, cars have entered more and more households, and the safe operation of cars is of great significance to improving personal safety. Among the safety equipment in cars, fire extinguishers are the most important tools, and fires are easiest to extinguish in their early stages. This requires people to be able to quickly grab fire extinguishers and fight off initial fires.

[0003] Existing fire extinguisher storage designs include seat / trunk integrated, chassis integrated, and traditional bracket fixed types. Among them, the seat / trunk integrated type embeds the fire extinguisher under the seat through a deflection bracket structure, but it has the problem of a long access path (requiring manual lifting of the seat component) and may affect the strength of the seat. The chassis integrated type uses a pipe locking structure, which improves the emergency response speed, but is limited by the chassis installation space and has a high maintenance difficulty. The traditional bracket fixed type does not solve the vibration interference problem when integrated with the side wall of the pedal.

[0004] As can be seen from the above, the existing design of fire extinguisher storage locations has problems such as low space utilization, low retrieval efficiency, and structural conflicts. Summary of the Invention

[0005] The purpose of this invention is to provide a vehicle fire extinguisher fixing system, a method of use, and a vehicle, in order to solve the technical problems of low space utilization, low retrieval efficiency, and structural conflicts in the existing fire extinguisher storage location design.

Triggered state: The information response module responds to the external fire alarm emergency signal and feeds the external fire alarm emergency signal back to the control system. The control system generates an instruction to open the clamping space. Response status: The drive motor drives the clamping arm to rotate and open the clamping space. When the fire extinguisher is removed, the control system sends a signal to the vehicle alarm system to activate the vehicle alarm device and sends a signal to the vehicle emergency lighting system to turn on the emergency lighting inside and outside the vehicle. Reset state: After the fire extinguisher is put back into the clamping space, the control system generates a command to close the clamping space, and the drive motor drives the clamping arm to rotate and close the clamping space.

[0028] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings.

[0029] The specific structure is as follows: Figure 1 and Figure 2 As shown.

[0030] This embodiment provides a vehicle fire extinguisher fixing system, including: CNSL assembly 1, fixing device 2 and fire extinguisher 3; CNSL assembly 1 is provided with storage space 4, fixing device 2 is disposed in storage space 4; fire extinguisher 3 is placed in storage space 4 through fixing device 2.

[0031] In this embodiment, the fire extinguisher 3 is placed in the storage space 4 by the fixing device 2, which not only improves the space utilization rate of the storage space 4 of the CNSL assembly 1, but also makes it convenient to use and effectively reduces the retrieval time. At the same time, it solves the problem of adapting the traditional fixing method to special spaces.

[0032] In this embodiment, the fixing device 2 can be a trough or other structure that can fix the fire extinguisher 3. However, it should be noted that the fixing structure not only needs to be able to fix the fire extinguisher 3, but also needs to be able to remove the fire extinguisher 3 when it is needed.

[0033] In the optional technical solution of this embodiment, the fixing device 2 includes a fixing base 5, an adjustable magnetic snap fastener, and a clamping assembly; the fixing base 5 is installed on the inner wall of the CNSL assembly 1 via the adjustable magnetic snap fastener; the clamping assembly is disposed on the fixing base 5, and the clamping assembly has an opening and closing clamping space; the fire extinguisher 3 is disposed within the clamping space. The structure is simple, and the fire extinguisher 3 is stably fixed by clamping.

[0034] In the optional technical solution of this embodiment, the clamping assembly includes a clamping arm 6 and a drive motor; the clamping arm 6 is mounted on the fixed base 5 via a rotating shaft; the drive motor is used to drive the clamping arm 6 to rotate to open and close the clamping space. This achieves automated opening and closing of the clamping space.

[0035] Specifically, the fixed base 5 is made of high-strength and lightweight carbon fiber composite material, and its shape is precisely adapted to the storage space 4 of the CNSL assembly 1. It connects to the inner wall of the storage space 4 via multiple sets of adjustable magnetic clips, adapting to variations in the material and thickness of the inner wall of the storage space 4 for different vehicle models, ensuring stability and preventing displacement during vehicle movement. The clamping assembly is mounted on the fixed base 5 and consists of two symmetrical electric clamping arms 6. The flexible rubber sleeves on the inner side of the clamping arms 6 have anti-slip textures, allowing for tight clamping of fire extinguisher cylinders 3 of different diameters while protecting the surface of the fire extinguisher 3. The clamping arms 6 are connected to a drive motor via a high-precision ball screw, powered by the vehicle's power supply, enabling precise control of the opening and closing movements of the clamping arms 6.

[0036] In the optional technical solution of this embodiment, an information response module is also included. The information response module is used to respond to external fire alarm emergency signals to generate an instruction to open the clamping space, control the drive motor to open the clamping arm 6 to open the clamping space, so that the fire extinguisher 3 can be taken out and used.

[0037] In the optional technical solutions of this embodiment, the information response module may include a voice command recognition unit and / or a biometric detection unit; preferably, the information response module includes a voice command recognition unit and a biometric detection unit and forms an intelligent sensing network multi-source triggering system.

[0038] Specifically, the voice command recognition unit integrates a high-sensitivity microphone array connected to the vehicle control system. Utilizing advanced deep learning voice recognition algorithms, it monitors the in-vehicle voice environment in real time. Upon detecting the keyword "fire hazard" and confirming the voiceprint originates from authorized personnel, it quickly sends a trigger signal to the control system, exhibiting strong noise immunity. The biometric detection module utilizes in-cabin pressure sensors (model 320) distributed in easily struck locations such as the driver's seat armrest and center console. When a striking action is detected, the sensors collect pressure data. If the pressure exceeds a preset threshold (50N±5%) and lasts for 0.2-0.5 seconds, it is considered a valid strike, and a trigger signal is sent to the control system. Multi-dimensional feature analysis prevents false triggers. The control system receives trigger signals from the voice command recognition unit and the biometric detection unit. After logical judgment and data fusion, it sends a control command to the drive motor of the clamping assembly. The drive motor responds, causing the clamping arm 6 to open, unlocking the mechanical locking structure for easy removal of the fire extinguisher 3. Simultaneously, the control system is linked with the vehicle alarm system and emergency lighting system, automatically activating the alarm and emergency lighting upon triggering.

[0039] In the optional technical solution of this embodiment, a status monitoring module is also included, which is installed in the storage space 4 and used to monitor the status information of the fire extinguisher 3. This module monitors the status of the environment in which the fire extinguisher 3 is located to ensure that the fire extinguisher 3 is in normal condition and can be used at any time.

[0040] In the optional technical solution of this embodiment, the status monitoring module includes at least one of a position sensor, a vibration sensor, and a temperature sensor; preferably, the status monitoring module includes a position sensor, a vibration sensor, and a temperature sensor; wherein, the position sensor is used to monitor the position information of the fire extinguisher 3; the vibration sensor is used to monitor the vehicle vibration information at the fire extinguisher 3; and the temperature sensor is used to monitor the temperature information at the fire extinguisher 3.

[0041] Specifically, a position sensor, vibration sensor, and temperature sensor are integrated into the fixing device 2. The position sensor monitors the position of the fire extinguisher 3, sending information and alerting the control system when it is abnormally displaced or removed; the vibration sensor detects vehicle vibration, warning the driver when it is abnormally severe; the temperature sensor monitors the ambient temperature, initiating a multi-source triggering system self-test program, issuing an alarm, and preparing the fire extinguisher 3 for quick retrieval when the temperature exceeds a preset safety threshold (e.g., 60°C). Furthermore, the status monitoring module can upload data to the vehicle remote monitoring platform for easy understanding of the operational status of the vehicle-mounted fire extinguisher 3 fixing system.

[0042] In the optional technical solution of this embodiment, the CNSL assembly 1 is provided with a through hole 7, which extends through both the left and right sides of the CNSL assembly 1 and is connected to the storage space 4. This facilitates the access of the fire extinguisher 3.

[0043] This embodiment provides an automobile, including a control system and the aforementioned vehicle fire extinguisher fixing system. Therefore, the technical advantages and effects achieved by this automobile include those achieved by the aforementioned vehicle fire extinguisher fixing system, which will not be repeated here.

[0044] In this embodiment, the installation steps of the vehicle fire extinguisher fixing system are as follows: Installation of Mounting Base 5: Carefully place Mounting Base 5 into the through-type storage space 4 at the bottom of the CNSL assembly. Carefully adjust its position to ensure that the multiple adjustable magnetic clips on Mounting Base 5 are precisely aligned with the inner wall of the storage space 4. During adjustment, use measuring tools, such as a tape measure, to ensure the accuracy of the Mounting Base 5's installation position, aligning it as closely as possible with the central axis of the storage space 4 to improve overall stability. Once the position is confirmed, press the installation start button on Mounting Base 5. At this time, the electromagnetic coil inside the adjustable magnetic clips is energized, generating a strong magnetic force that automatically adheres to the wall of the storage space 4. Simultaneously, the adjustable elastic joints of the magnetic clips begin to work, adaptively adjusting according to the actual shape and thickness of the wall until they are tightly fitted. Finally, further reinforce the connection with the built-in fastening bolts. Use the included wrench to tighten the bolts to ensure that Mounting Base 5 remains stable and does not shift during vehicle operation. When tightening bolts, the specified torque value must be followed. A torque wrench can be used for precise control to avoid damaging the base or wall due to excessive torque. The torque value is generally set between 10-15 N•m.

[0045] Clamping Assembly Installation: Mount the two electric clamping arms 6 of the clamping assembly onto the fixed base 5 via a rotating shaft, ensuring the rotating shaft is securely installed and the clamping arms 6 can rotate freely. During installation, clean the mounting holes of the rotating shaft to remove impurities and apply an appropriate amount of lubricant, such as lithium-based grease, to reduce rotational friction and extend service life. Connect the high-precision ball screw to the drive motor, using a coupling to precisely align them, ensuring the coaxiality error between the drive motor output shaft and the ball screw is controlled within a very small range, generally not exceeding ±0.05mm, to ensure stable and efficient power transmission. Then, fix the drive motor in the preset installation position and tighten the bolts to ensure the drive motor is securely installed and will not shift or vibrate during operation. Connect the vehicle power supply to power the drive motor, selecting the vehicle's constant power interface, such as the specific fuse location in the vehicle's fuse box, using a dedicated power cable for connection, and installing overload protection devices, such as fuses or circuit breakers, to promptly cut off the circuit in case of abnormal current, protecting the drive motor and the vehicle's electrical system. At the same time, connect the control line of the drive motor to the control system interface to ensure that the control line is connected correctly and the signal transmission is stable.

[0046] Installation of the Intelligent Sensing Network Multi-Source Trigger System: For the voice command recognition unit, install a high-sensitivity microphone array inside the vehicle, above the driver's seat, such as near the rearview mirror or below the headliner. This location allows the microphone to better capture voice commands from occupants and reduces external noise interference. Secure the microphone array using a dedicated mounting bracket, ensuring a firm installation and that the microphones face the interior space. Then, connect the microphone array's data cable to the control system interface. Use well-shielded cables, such as twisted-pair cables, to prevent electromagnetic interference. For the biometric detection unit, install the cabin pressure sensor (model 320) at preset locations on the driver's seat armrest and center console surface. Before installation, apply a layer of dedicated sensor mounting adhesive, such as epoxy resin, to the mounting location to firmly attach the pressure sensor, ensuring a tight fit between the sensor and the mounting surface for accurate detection of pressure changes caused by tapping. Connect the pressure sensor's leads to the control system interface, paying attention to the connection sequence and polarity to avoid incorrect connections that could malfunction the pressure sensor.

[0047] Status monitoring module installation: Position sensor: Install a position sensor at the contact point between the fixing device 2 and the fire extinguisher 3, such as the inside of the clamping arm 6 near the bottom of the fire extinguisher 3. Secure the position sensor to the clamping arm 6 with screws, ensuring accurate installation and real-time monitoring of the fire extinguisher 3's position. Connect the position sensor wiring to the control system, taking care to avoid cable tangling and compression during wiring to ensure smooth signal transmission. Vibration sensor: Install the vibration sensor at the bottom of the fixing base 5 near the edge, securing it with screws or strong adhesive. The vibration sensor should be installed in a location that effectively detects vehicle vibrations. Calibrate after installation to ensure the vibration sensor accurately senses vibration intensity and frequency. Connect the vibration sensor wiring to the control system, again paying attention to wiring protection and connection quality. Temperature sensor: Install a temperature sensor near the environment surrounding the fire extinguisher 3, such as on the side of the fixing base 5 near the fire extinguisher 3's cylinder. Secure the temperature sensor using a dedicated sensor mounting kit to ensure accurate measurement of the ambient temperature around the fire extinguisher 3. Connect the temperature sensor to the control system, calibrate the temperature sensor, and set the preset safe temperature threshold, such as 60℃.

[0048] System Debugging: After completing the installation of all hardware devices, a comprehensive debugging of the entire fixed device 2, the intelligent sensing network multi-source triggering system, and the status monitoring module is performed. First, check whether the installation of each component is secure and whether the connection lines are correct and not loose. Then, connect the vehicle power and start the control system. Test the voice command recognition unit by shouting "Fire danger" from different positions and at different volumes inside the vehicle to check whether the system can accurately recognize the voice command and respond. If the recognition is inaccurate, the parameters of the voice recognition algorithm can be fine-tuned through the control system's settings interface, such as adjusting the voice recognition sensitivity and noise reduction parameters. Test the biometric detection unit by using a simulated tapping tool to tap the pressure sensor installation locations on the driver's seat armrest and center console with different forces and frequencies to check whether the system can accurately detect valid tapping actions and send trigger signals. If the detection is inaccurate, check whether the pressure sensor is installed correctly and recalibrate the sensor's pressure threshold and detection time parameters. The operation of the drive motor of the clamping assembly was tested. Control commands were sent to the control system to open and close the clamping arm 6, checking whether the movement of the clamping arm 6 was smooth and whether the clamping force was appropriate. If the clamping arm 6 was found to be stuck or the clamping force was insufficient, the power supply of the drive motor was checked to ensure it was normal and whether the ball screw needed lubrication or adjustment. The status monitoring module was tested by manually moving the fire extinguisher 3 to check whether the position sensor could detect the position change in time and send a signal to the control system; vibration simulation equipment was used to apply vibrations of different intensities to the fixed base 5 to check whether the vibration sensor could accurately alarm; heating equipment was used to raise the ambient temperature around the fire extinguisher 3 to check whether the temperature sensor could activate the relevant program when the temperature exceeded the preset threshold. Problems found during the testing process were promptly investigated and resolved to ensure that the entire system could work normally.

[0049] This embodiment provides a method for using a vehicle fire extinguisher securing system, which is applied to the aforementioned vehicle. Therefore, the technical advantages and effects achieved by this method of using the vehicle fire extinguisher securing system include the technical advantages and effects achieved by the aforementioned vehicle, which will not be repeated here.

[0050] The usage method includes: Standby state: The information response module is in a state of waiting to respond to external fire alarm emergency signals in real time. The status monitoring module monitors the status information of fire extinguisher 3 in real time. The status information of fire extinguisher 3 includes normal status information and abnormal status information. When the status monitoring module detects abnormal status information, it feeds the abnormal status information back to the control system, and the control system generates a prompt message; Trigger state: The information response module responds to the external fire alarm emergency signal and feeds the external fire alarm emergency signal back to the control system to form a trigger signal; Response state: The drive motor drives the clamping arm 6 to rotate and open the clamping space. When the fire extinguisher 3 is removed, the control system sends a signal to the vehicle alarm system to activate the vehicle alarm device and sends a signal to the vehicle emergency lighting system to activate the emergency lighting inside and outside the vehicle; Reset state: After the fire extinguisher 3 is put back into the clamping space, the control system generates a command to close the clamping space, and the drive motor drives the clamping arm 6 to rotate and close the clamping space.

[0051] Specifically, in standby mode: During normal vehicle operation, the vehicle-mounted fire extinguisher 3 is securely fixed to the mounting device 2. The intelligent sensing network multi-source triggering system is in standby mode, the microphone array of the voice command recognition unit monitors the in-vehicle voice environment in real time, and the pressure sensor of the biometric detection unit is ready to detect tapping actions. The status monitoring module continues to operate, with the position sensor monitoring in real time whether the fire extinguisher 3 is in the correct fixed position. If the position of the fire extinguisher 3 deviates abnormally, it will immediately send a position abnormality signal to the control system; the vibration sensor monitors the vibration during vehicle operation in real time, and when the vibration intensity or frequency exceeds the preset normal range, it sends a vibration abnormality signal to the control system; the temperature sensor monitors the ambient temperature around the fire extinguisher 3, and once the temperature exceeds the preset safety threshold (e.g., 60℃), it sends a temperature abnormality signal to the control system. After receiving these abnormal signals, the control system will display corresponding prompts on the vehicle's dashboard or central control display screen, reminding the driver to pay attention to the status of the mounting device 2 of the vehicle-mounted fire extinguisher 3. Meanwhile, the status monitoring module collects data such as location, vibration, and temperature and uploads it to the vehicle's remote monitoring platform via a wireless transmission module, so that the vehicle owner or vehicle management department can understand the working status of the fixing device 2 of the vehicle fire extinguisher 3 in real time.

[0052] Triggering Status: When a fire or other emergency occurs inside the vehicle requiring the use of fire extinguisher 3, the driver or passengers can trigger the use of fire extinguisher 3 in two ways. First, by loudly shouting "Fire danger!" The microphone array of the voice command recognition unit receives the voice signal and transmits it to the control system. The control system first performs noise reduction processing on the voice signal, then uses a deep learning voice recognition algorithm to analyze the voice content. When the keyword "fire danger" is identified, the voiceprint is further identified to confirm that the command originates from an authorized person inside the vehicle (such as the driver). If the voiceprint recognition is successful, the control system immediately determines it as a valid trigger signal. Second, by forcefully striking a preset location, such as the driver's seat armrest. When the pressure sensor detects the striking action, it quickly collects pressure data and transmits the data to the control system. The control system analyzes the pressure data to determine whether the pressure value exceeds a preset force threshold (50N±5%), and simultaneously checks whether the pressure duration is within a reasonable range of 0.2-0.5 seconds. If both the pressure value and duration meet the preset conditions, the control system determines it as a valid striking action and uses it as a trigger signal.

[0053] Response Status: Upon receiving a valid trigger signal, the control system immediately sends a control command to the drive motor of the clamping assembly. Upon receiving the command, the drive motor quickly starts, driving the high-precision ball screw. The rotation of the ball screw converts the rotational motion into linear motion through the nut, causing the two electric clamping arms 6 to quickly open and create the clamping space. Simultaneously, the control system controls the unlocking mechanism, causing the mechanical locking structure to quickly disengage from the fire extinguisher 3. After this series of actions is completed, the driver or passenger can quickly remove the fire extinguisher 3 to extinguish the fire. Simultaneously, the control system automatically sends a signal to the vehicle alarm system, activating the alarm device and emitting a loud siren to alert surrounding personnel to the emergency situation; it also sends a signal to the vehicle emergency lighting system, activating the interior and exterior emergency lighting to provide adequate lighting for the fire extinguishing operation.

[0054] Reset Status: After the fire extinguishing operation is completed, the fire extinguisher 3 is returned to the fixing device 2. Upon detecting that the fire extinguisher 3 has returned to its original position, the position sensor immediately sends a return signal to the control system. Upon receiving the signal, the control system reverses the drive motor, causing the ball screw to rotate in the opposite direction and close the clamping space, allowing the clamping arm 6 to re-clamp the fire extinguisher 3. Simultaneously, the control system controls the mechanical locking structure to re-lock the fire extinguisher 3, ensuring it is securely fixed. During the clamping process, the status monitoring module monitors the clamping force in real time to ensure it is appropriate—neither too loose (causing the fire extinguisher 3 to shake) nor too tight (damaging the fire extinguisher 3). Once the fire extinguisher 3 is secured, the status monitoring module updates the status information of the fire extinguisher 3 and uploads it to the vehicle remote monitoring platform, reverting to the normal monitoring mode.

[0055] Routine Maintenance Points: Maintenance of Fixed Base 5 and Clamping Components: Regularly check the adsorption force of the adjustable magnetic buckle of the fixed base 5. Use a professional magnetic testing tool, such as a gaussmeter, to test the magnetic field strength of the magnetic buckle. If the adsorption force of the magnetic buckle weakens and falls below the specified standard value, it may be due to aging or damage of the electromagnetic coil, requiring timely replacement of the magnetic buckle. Simultaneously, check for loose fastening bolts. Use a wrench to check the tightness of each bolt; if any are loose, retighten them to the specified torque value. Monthly inspection and maintenance of the electric clamping arm 6 and drive motor of the clamping component. Check the flexible rubber sleeve of the clamping arm 6 for wear and aging. If the rubber sleeve is severely worn and the surface anti-slip texture disappears, it will affect the clamping effect on the fire extinguisher 3; a new rubber sleeve should be replaced promptly. Add an appropriate amount of grease, such as lithium-based grease, to the rotating shaft and ball screw of the clamping arm 6 to ensure smooth movement and reduce wear. Check the operating status of the drive motor. Use a motor testing instrument to test the current, speed and other parameters of the drive motor. If the drive motor operates abnormally, such as unstable speed or excessive current, it may be an internal fault of the motor, and the drive motor needs to be repaired or replaced in time.

[0056] Maintenance of the Intelligent Sensing Network Multi-Source Triggering System: Monthly functional tests are conducted on the intelligent sensing network multi-source triggering system. Accuracy tests are performed on the voice command recognition unit by repeatedly calling "fire hazard" under varying environmental noise conditions to check if the system's voice recognition accuracy meets the specified standards. If the voice recognition accuracy decreases, it may be due to dust accumulation or moisture on the microphone array, or the voice recognition algorithm may need updating. To address this, clean the microphone surface with a clean, soft brush, dry the microphone array in a dry environment, or update the voice recognition algorithm via the control system's software upgrade function. Sensitivity tests are performed on the biometric detection unit by using a simulated tapping tool to perform tapping operations of different forces and frequencies at the pressure sensor installation location to check if the system can accurately detect valid tapping actions. If the detection sensitivity decreases, check if the pressure sensor is loose or has surface stains, and recalibrate the pressure sensor's pressure threshold and detection time parameters. If the pressure sensor is damaged, replace it with the same model immediately. Check the connection lines between the control system and each module for damage or looseness; repair or replace any wiring problems found. Regularly upgrade the control system software to improve system performance and stability, and optimize the collaborative efficiency between modules.

[0057] Status monitoring module maintenance: Monitor the operating status of the sensors in the status monitoring module. Regularly clean dust and debris from the surfaces of the position sensor, vibration sensor, and temperature sensor. Gently wipe the sensor surfaces with a clean, soft cloth to ensure accurate sensor data acquisition. Check that the sensors are securely installed; if loose, re-secure the sensors. Perform regular calibration of the temperature sensor using a standard temperature source, adjusting the calibration parameters to ensure accurate temperature measurements. If a sensor malfunctions, such as the position sensor failing to detect position changes, the vibration sensor issuing false alarms, or the temperature sensor showing abnormal readings, replace it with the same model immediately and recalibrate and test it to ensure the status monitoring and feedback module functions properly, providing reliable assurance for the safe operation of the vehicle-mounted fire extinguisher 3 and fixing device 2.

[0058] This application achieves several significant technical benefits through a unique technical solution: Highly efficient emergency retrieval: The introduction of a multi-source triggering system with an intelligent sensing network greatly shortens the time required to retrieve the fire extinguisher 3. The voice command recognition unit instantly sends a signal after detecting "fire hazard" and confirming the voiceprint, while the biometric detection unit rapidly responds to striking actions that meet conditions such as force and duration. Under the dual triggering method, the control system drives the clamping arm 6 to open and unlock the mechanical locking structure within milliseconds. Compared to the traditional manual operation's retrieval time of over 15 seconds, this significantly improves the fire extinguishing response speed, gaining valuable time to control the fire. Intelligent integration upgrade: Deep integration with the vehicle's intelligent system. On the one hand, utilizing the vehicle's existing sensor resources, when the temperature sensor detects an abnormality such as an ambient temperature exceeding 60℃ that may cause a fire, the intelligent sensing network multi-source triggering system automatically activates self-check and alarm, preparing for fire extinguishing in advance. On the other hand, the status monitoring module feeds back the fire extinguisher 3's position, vibration, temperature, and other status data to the vehicle's computer in real time, displaying alerts on the instrument panel or central control screen, and can also upload data to a remote monitoring platform, allowing vehicle owners or management departments to monitor the situation in real time and achieve comprehensive intelligent collaboration. Special space adaptation optimization: A suitable fixing base 5 was designed for the lower through-type storage space 4 of the CNSL assembly 1. High-strength, lightweight carbon fiber composite material combined with multiple adjustable magnetic clips can tightly fit the inner wall of this space in different vehicle models, adapting to changes in wall material and thickness, ensuring a stable installation. Vibrations and bumps during vehicle operation will not cause the fixing device 2 to shift, ensuring the fire extinguisher 3 is always usable, solving the adaptation problem of traditional fixing methods in special spaces.
