Description

Technical Field

[0001] This application belongs to the technical field of vehicle-mounted fire extinguishing devices, and more specifically, relates to a vehicle-mounted auxiliary panel fire extinguishing device and a vehicle. Background Technology

[0002] In modern automobiles, safety and reliability are core design concerns. However, vehicles pose a fire hazard after a collision. Therefore, fire extinguishing devices are usually installed in vehicles. Commonly used vehicle fire extinguishers include water-based fire extinguishers and dry powder fire extinguishers, which can be triggered when a fire occurs and extinguish the fire by spraying extinguishing agent into the fire area.

[0003] In the existing technology, the vehicle-mounted fire extinguishing system is usually located in the trunk or engine compartment and requires manual operation to spray fire extinguishing agent; however, the trunk and engine compartment are also easily damaged in the event of a vehicle collision. Therefore, the vehicle-mounted fire extinguishing device is easily damaged in the collision, which leads to the failure of the fire extinguishing device and the inability to respond in time, thus delaying the best rescue time and causing huge property and life safety losses to passengers. Utility Model Content

[0004] The purpose of this application is to provide a vehicle-mounted sub-panel fire extinguishing device and a vehicle, which aims to solve the technical problems of existing vehicle-mounted fire extinguishing devices being complex to operate and easily damaged and malfunctioning when the vehicle is involved in a collision.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: Firstly, a vehicle-mounted sub-panel fire extinguishing device is provided, comprising: A fire extinguisher housing is located inside the vehicle's secondary instrument cluster and fixed to the front side of the vehicle's secondary instrument panel. The fire extinguisher housing is equipped with a drive assembly for driving the fire extinguisher housing and the secondary instrument panel to slide along the vehicle's longitudinal direction. The fire extinguisher housing is equipped with an outlet. The fire extinguisher body is housed within the fire extinguishing box; a spray pipe is connected to the fire extinguisher body, and the outlet of the spray pipe corresponds to the inner and outer positions of the outlet; and The controller is electrically connected to the sensing components on the vehicle body; the controller is also electrically connected to the drive assembly and the fire extinguisher body. The drive assembly is used to drive the fire extinguishing box to slide backward into the carriage, and the fire extinguisher body is used to spray extinguishing agent from the spray outlet.

[0006] Compared with the prior art, the solution shown in this application installs the fire extinguisher body inside the fire extinguishing box and fixes the fire extinguishing box to the front of the vehicle's passenger dashboard to prevent the fire extinguisher body from being damaged in the event of a vehicle collision. The fire extinguishing box outside the fire extinguisher body increases the protective effect, helps to protect the integrity and effectiveness of the fire extinguisher body, and improves fire extinguishing safety.

[0007] Furthermore, this application includes a controller electrically connected to the fire extinguisher body, enabling automatic spraying of extinguishing agent from the fire extinguisher body. The controller is also electrically connected to the drive assembly of the fire extinguisher housing, allowing the drive assembly to slide the fire extinguisher housing into the vehicle compartment. This facilitates bringing the outlet of the fire extinguisher housing closer to the fire location inside the compartment. Since the outlet corresponds to the nozzle of the fire extinguisher body, the extinguishing agent can be sprayed from both the nozzle and outlet, bringing the sprayed extinguishing agent closer to the fire area inside the compartment, thus improving the fire extinguishing effect.

[0008] Therefore, the vehicle-mounted auxiliary panel fire extinguishing device provided in this application is beneficial to maintaining the integrity and effectiveness of the fire extinguisher body during a collision, and can realize the automatic sliding out of the fire extinguishing box and the automatic spraying of the fire extinguisher body through the controller, which can effectively simplify the operation process and improve the fire extinguishing efficiency.

[0009] In conjunction with the first aspect, in one possible implementation, the spray pipe is a telescopic spray pipe, and the telescopic end of the telescopic spray pipe is provided with the spray outlet; wherein, the telescopic spray pipe has a closed state in which it retracts into the fire extinguishing box so that the spray outlet is placed in the outlet, and the telescopic spray pipe also has an open state in which it extends out of the outlet so that the spray outlet is placed outside the outlet.

[0010] By setting the spray nozzle as a telescopic nozzle, the nozzle can be extended to bring the nozzle outlet closer to the fire site, which helps to improve the targeting and effectiveness of fire suppression.

[0011] In some embodiments, the injection tube includes: The multi-stage connecting pipes are arranged in a sequentially nested structure from the inside to the outside, and one end of the inner connecting pipe has the freedom to extend outward to the adjacent outer connecting pipe; one end of the outermost connecting pipe is connected to the fire extinguisher body. Multiple sets of transmission components; a set of transmission components is provided between each pair of adjacent connecting pipes, and the transmission components are used to drive one end of the corresponding inner connecting pipe to extend outward to the adjacent outer connecting pipe. The controller is electrically connected to multiple sets of transmission components, and the transmission components are used to drive the corresponding inner connecting pipe to extend and retract, so that the telescopic nozzle switches between the open state and the closed state.

[0012] By setting the telescopic nozzle as a multi-stage inner and outer connecting pipe, on the one hand, it is beneficial to reduce the length of the nozzle in the retracted state, thus facilitating the storage of the nozzle; on the other hand, it is beneficial to extend the multi-stage connecting pipe, thereby increasing the extension length of the nozzle and bringing the nozzle outlet closer to the fire location; by setting a transmission component and electrically connecting the transmission component to the controller, the extension of the multi-stage connecting pipe can be automatically controlled, which is beneficial to improving the extension and retraction efficiency of the nozzle.

[0013] For example, the transmission assembly includes: The first motor is fixed on the outer peripheral wall of the outer connecting tube; the power output shaft of the first motor extends radially into the outer connecting tube. A rotating gear is located at the extension end of the power output shaft; and A rack is fixed to the outer peripheral wall of the inner connecting tube and extends along the axial direction of the connecting tube; the rack meshes with the rotating gear. The first motor is electrically connected to the controller; the first motor is used to drive the rotating gear to rotate, so that the rotating gear drives the rack to move axially along the connecting pipe.

[0014] The first motor drives the rack to move by rotating the gear, which in turn causes the rack to extend one end of the corresponding inner connecting tube outward from the outer connecting tube, thus facilitating the automatic extension of the inner connecting tube.

[0015] In some embodiments, a tear plate is provided at the outlet, and the telescopic end of the telescopic nozzle is used to break the corresponding tear plate to extend out of the fire extinguishing box.

[0016] By installing a tear-off plate, the inside of the fire extinguishing chamber can be kept dustproof when not in use, and when in use, the spray nozzle can easily pass through the tear-off plate to extend out of the fire extinguishing chamber.

[0017] In conjunction with the first aspect, in one possible implementation, a first rotating shaft is provided at the nozzle of the injection pipe, the first rotating shaft extending radially along the injection pipe; one end of the first rotating shaft extends out of the injection pipe and is connected to a second motor; a first blade is provided on the first rotating shaft. The second motor is electrically connected to the controller; the second motor is used to drive the first blade to rotate around the first rotating shaft in order to adjust the spray gap between the first blade and the inner wall of the spray pipe.

[0018] In the initial state, the first blade covers the nozzle, and the spray gap between the first blade and the inner peripheral wall of the spray pipe is zero or very small. The second motor drives the first blade to rotate around the first rotating shaft, so that the spray gap between the first blade and the inner peripheral wall of the spray pipe gradually increases. At the same time, the spray direction of the extinguishing agent in the circumferential direction of the first rotating shaft can be adjusted.

[0019] In some embodiments, a second rotating shaft is provided at the nozzle of the spray pipe, and the axis of the second rotating shaft forms a preset angle with the axis of the first rotating shaft; one end of the second rotating shaft extends out of the spray pipe and is connected to a third motor; a second blade is provided on the second rotating shaft; The third motor is electrically connected to the controller; the third motor is used to drive the second blade to rotate around the second rotating shaft in order to adjust the spray gap between the second blade and the inner wall of the spray pipe.

[0020] By further configuring the second blade, the spraying gap between the second blade and the inner wall of the spray pipe can be adjusted to further adjust the spraying direction of the extinguishing agent in the circumferential direction of the second rotating shaft, and further adjust the spray outlet of the extinguishing agent.

[0021] In conjunction with the first aspect, in one possible implementation, there are two outlets, which are symmetrically arranged along the left-right direction of the vehicle body; The fire extinguisher body is equipped with two sets of spray pipes, and the two sets of spray pipes are configured one-to-one with the two outlets.

[0022] By symmetrically setting two outlets and two sets of spray pipes on the left and right, the extinguishing agent can be sprayed out in the left and right directions. When the fire is large, the extinguishing efficiency can be improved; when the fire is small and concentrated on one side, the spraying of the extinguishing agent can be more targeted, which is conducive to improving the extinguishing effect.

[0023] In conjunction with the first aspect, in one possible implementation, the driving component includes: The guide rail assembly extends along the front-rear direction of the vehicle body and is located within the auxiliary instrument assembly, and is fixed to the vehicle floor; Multiple sets of drive wheels are arrayed at the bottom of the fire extinguishing box and placed within the guide rail assembly; and A fourth motor is mounted on the fire extinguishing box, and the output of the fourth motor is poweredly connected to one of the drive wheels; the fourth motor is electrically connected to the controller.

[0024] The controller controls the fourth motor to drive the drive wheel to rotate, thereby causing the fire extinguishing box and the fire extinguisher body to slide on the guide rail assembly to achieve the extension of the fire extinguishing box; the guide rail assembly is used to guide the sliding of the fire extinguishing box and prevent the fire extinguishing box from deviating during the movement.

[0025] Secondly, embodiments of this application also provide a vehicle including the aforementioned vehicle-mounted sub-panel fire extinguishing device.

[0026] The vehicle provided in this application embodiment, because it includes the above-mentioned vehicle-mounted sub-panel fire extinguishing device, has all the beneficial effects of the above-mentioned vehicle-mounted sub-panel fire extinguishing device, which is conducive to maintaining the integrity and effectiveness of the fire extinguisher body during a collision, and can effectively simplify the fire extinguishing operation process and improve the fire extinguishing efficiency.

[0030] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0031] It should be noted that when an element is referred to as being "set on" another element, it can be directly on or indirectly on that other element. It should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are used only for the convenience of describing this application and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0032] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "a number" means two or more, unless otherwise explicitly specified.

[0033] It should be noted that the directions or positional relationships indicated by "front", "rear", "inner", "outer", "up", and "down" in this embodiment are based on the vehicle's own orientation. The front of the vehicle represents "front", the rear of the vehicle represents "rear", the top of the vehicle represents "up", the bottom of the vehicle represents "down", the "inner" side refers to the side facing the driver's cab, and the "outer" side refers to the side facing the driver's cab.

[0034] In addition, the front-rear direction of the vehicle body as defined in the embodiments of this application refers to the front-rear direction of the vehicle's forward direction during driving; the left-right direction of the vehicle body as defined refers to the left-right direction of the vehicle's forward direction during driving; and the up-down direction of the vehicle body as defined refers to the up-down direction of the vehicle's forward direction during driving.

[0035] It is important to understand that electric vehicles pose a fire hazard after a collision, and the fire usually originates in the power battery system. In the current technology, the power battery system of electric vehicles is very large in size and weight, usually exceeding 100 kilograms. Therefore, the power battery system is generally placed under the floor in the middle of the vehicle body to ensure stable support and safety.

[0036] Therefore, when a power battery system catches fire, traditional car fire extinguishers are installed in the trunk or engine compartment. As a result, for automatic fire extinguishers, the spray range of the extinguishing agent is relatively concentrated at the front or rear of the extinguisher. Furthermore, in the event of a collision, the extinguisher may also be affected due to its special location, thus impacting its effectiveness. Portable fire extinguishers, on the other hand, require operators to retrieve them and perform targeted fire suppression. Therefore, traditional fire extinguishers suffer from technical problems such as complex operation and poor fire suppression effectiveness.

[0037] Please refer to the following: Figures 1 to 6 The following describes the vehicle-mounted sub-panel fire extinguishing device and the vehicle provided in this application. The vehicle-mounted sub-panel fire extinguishing device includes a fire extinguishing box 1, a fire extinguisher body 2, and a controller. The fire extinguishing box 1 is located inside the vehicle's sub-instrument assembly and is fixedly connected to the front side of the vehicle's sub-instrument panel 3. The fire extinguishing box 1 is equipped with a drive assembly 4, which is used to drive the fire extinguishing box 1 and the sub-instrument panel 3 to slide along the vehicle's front-rear direction. The fire extinguishing box 1 is equipped with an outlet 11 for the passage of fire extinguishing agent. The fire extinguisher body 2 is located inside the fire extinguishing box 1. A spray pipe 21 is connected to the fire extinguisher body 2, and the spray outlet 22 of the spray pipe 21 corresponds to the inner and outer positions of the outlet 11. The controller is electrically connected to a sensing component on the vehicle body. The controller is also electrically connected to the drive assembly 4 and the fire extinguisher body 2. The drive assembly 4 is used to drive the fire extinguishing box 1 to slide backward into the vehicle compartment, and the fire extinguisher body 2 is used to spray fire extinguishing agent from the spray outlet 22.

[0038] It should be noted that the secondary instrument panel 3 is an interior component located on the driver's side passage, between the two front seats. The secondary instrument panel 3 is an important supplementary structure to the instrument panel. In this application, the fire extinguisher housing 1 is installed on the front side of the secondary instrument panel 3, which can be hidden on the platform near the front of the secondary instrument assembly; and when needed, the fire extinguisher housing 1 is slid into the vehicle compartment by the drive assembly 4, thereby bringing the fire extinguisher body 2 closer to the power battery system for close-range targeted fire extinguishing.

[0039] It should be noted that in this application, the fire extinguisher box 1 is installed on the front side of the sub-dashboard 3. Here, "front" is based on the vehicle's front-to-back direction. The direction towards the front of the vehicle indicates the front, and the direction towards the trunk indicates the rear.

[0040] Since the spray pipe 21 in this application is connected to the fire extinguisher body 2, and its spray outlet 22 corresponds to the inner and outer positions of the outlet 11, when the controller controls the fire extinguisher body 2 to spray the extinguishing agent, the extinguishing agent is sprayed outward through the outlet 11.

[0041] In addition, the drive assembly 4 in this application is used to drive the fire extinguisher box 1 to slide along the front and rear direction of the vehicle. Therefore, the fire extinguisher box 1 has a retracted state and an open state. When the vehicle is in normal operation or stopped state, the fire extinguisher box 1 is in the retracted state.

[0042] It should be understood that the controller is used to receive the monitoring value of the sensing component, and when the controller receives the monitoring value of the sensing component exceeding the preset value, the controller is used to control the drive component 4 to slide the fire extinguishing box 1 backward into the compartment, and control the fire extinguisher body 2 to spray the extinguishing agent from the spray outlet 22.

[0043] In addition, the controller used in this application is a structure that integrates multiple control elements. The signal reception of the collision sensor and temperature sensor, the driving of the drive component 4, and the action of the fire extinguisher body 2 to spray the extinguishing agent are all controlled and realized by the corresponding control elements. Furthermore, the specific structure and connection method of each control element, as well as the corresponding control principle, are all existing technologies and will not be described in detail here.

[0044] Specifically, the sensing components used in this application include collision sensors and / or temperature sensors. The collision sensors mentioned in this application are usually located in the engine compartment, and the temperature sensors are usually connected in the passenger compartment. The number and installation location of the collision sensors and temperature sensors, as well as their specific structures and working principles, are all prior art and will not be described in detail here.

[0045] Therefore, the monitored values ​​include the collision intensity value monitored in real time by the collision sensor and the temperature value monitored in real time by the temperature sensor; the preset values ​​include the preset intensity value and the preset temperature value; after the controller receives the collision intensity value from the collision sensor exceeding the preset intensity value, and / or the monitored value from the temperature sensor received by the controller exceeds the preset temperature value, the controller controls the drive component 4 to operate and causes the fire extinguisher body 2 to spray the extinguishing agent.

[0046] Specifically, when a vehicle collision occurs, the collision sensor detects the collision signal and transmits it to the controller. When the collision intensity value received by the controller is greater than the preset intensity value, the controller controls the drive component 4 to operate. And / or the temperature sensor monitors the real-time temperature in the driver's compartment and transmits it to the controller. When the temperature value received by the controller exceeds the preset temperature value, the controller controls the drive component 4 to operate, so that the drive component 4 drives the fire extinguishing box 1 to slide towards the rear of the vehicle and brings the fire extinguishing box 1 closer to the interior of the vehicle compartment. At this time, the fire extinguishing box 1 is in the open state.

[0047] Compared with the prior art, the vehicle-mounted auxiliary panel fire extinguishing device provided in this application installs the fire extinguisher body 2 inside the fire extinguishing box 1 and fixes the fire extinguishing box 1 to the front side of the vehicle's auxiliary dashboard 3, so as to avoid the fire extinguisher body 2 being damaged in the event of a vehicle collision. Furthermore, the fire extinguishing box 1 outside the fire extinguisher body 2 can increase the protective effect, which is conducive to protecting the integrity and effectiveness of the fire extinguisher body 2 and improving fire extinguishing safety.

[0048] Furthermore, this application includes a controller electrically connected to the fire extinguisher body 2, enabling the automatic spraying of extinguishing agent by the fire extinguisher body 2. The controller is also electrically connected to the drive assembly 4 of the fire extinguishing box 1, allowing the drive assembly 4 to slide the fire extinguishing box 1 into the vehicle compartment. This facilitates the outlet 11 of the fire extinguishing box 1 approaching the fire location inside the vehicle compartment. Since the outlet 11 corresponds internally and externally to the nozzle 22 of the fire extinguisher body 2, the extinguishing agent can be sprayed from the nozzle 22 and outlet 11, bringing the sprayed extinguishing agent closer to the fire area inside the vehicle compartment, thus improving the fire extinguishing effect.

[0049] Therefore, the vehicle-mounted auxiliary panel fire extinguishing device provided in this application helps maintain the integrity and effectiveness of the fire extinguisher body 2 during a collision. Furthermore, it enables the automatic sliding out of the fire extinguisher housing 1 and the automatic spraying of the fire extinguisher body 2 via a controller, effectively simplifying the operation process and improving fire extinguishing efficiency. Thus, this vehicle-mounted auxiliary panel fire extinguishing device improves the reliability and safety of the fire extinguishing system, reducing the risk of failure due to damage to the fire extinguisher's position; the automatic triggering device can respond quickly in emergencies, effectively controlling the fire and protecting the safety of occupants; real-time sensor monitoring ensures timely activation of the fire extinguishing system, improving fire extinguishing efficiency; and the stable placement of the fire extinguisher reduces the risk of damage caused by vehicle vibration or collision, further improving system reliability.

[0050] Please see Figure 1 In some possible embodiments, the spray pipe 21 is a telescopic spray pipe, and the telescopic end of the telescopic spray pipe is provided with a spray outlet 22; wherein, the telescopic spray pipe has a closed state in which it retracts into the fire extinguishing box 1 so that the spray outlet 22 is placed in the outlet 11, and the telescopic spray pipe also has an open state in which it extends out of the outlet 11 so that the spray outlet 22 is placed outside the outlet 11.

[0051] The spray pipe 21 in this application is a telescopic spray pipe, which has a closed state where it retracts into the fire extinguishing housing 1, placing the spray outlet 22 inside the outlet 11, and an open state where it extends out of the outlet 11, placing the spray outlet 22 outside the outlet 11. Therefore, the spray pipe 21 can be extended to bring the spray outlet 22 closer to the fire location, which helps to improve the targeting and effectiveness of fire extinguishing.

[0052] In addition, the extension length of the telescopic nozzle can be adjusted according to actual needs to adjust the spray position of the extinguishing agent in the axial direction of the telescopic nozzle, thereby enhancing the flexibility and effectiveness of fire extinguishing.

[0053] Optionally, as a specific embodiment of the above-mentioned telescopic nozzle, the spray pipe 21 can also be a fixed pipe housed in the fire extinguishing box 1, and the nozzle outlet 22 of the fixed pipe is connected to the outlet 11.

[0054] Optionally, as a specific embodiment of the above-mentioned telescopic nozzle, the telescopic nozzle may be an electrically operated telescopic nozzle structure.

[0055] Optionally, as a specific embodiment of the aforementioned telescopic nozzle, the telescopic nozzle includes a multi-stage rotating pipe, and the multi-stage rotating pipes are arranged in a structure of sequential inner and outer connections. One end of the outermost rotating pipe is connected to the fire extinguisher body 2; and one end of the inner rotating pipe has the freedom to rotate out the adjacent outer rotating pipe along its axial direction. When the multi-stage telescopic pipe needs to extend, the corresponding outer rotating pipe can be rotated out by rotating the inner rotating pipe.

[0056] Optionally, adjacent spiral tubes can be driven by a drive motor and a gear transmission mechanism; specifically, a first gear is provided on the inner spiral tube, a drive motor is provided on the outer spiral tube, the power output shaft of the drive motor extends into the outer spiral tube along the radial direction of the spiral tube, and a drive gear is provided at its extended end, and the drive gear meshes with the first gear to achieve the extension of the inner spiral tube.

[0057] Please see Figure 3 and Figure 4 In some embodiments, the telescopic nozzle includes multiple connecting pipes and multiple sets of transmission assemblies 23; the multiple connecting pipes are arranged in a sequentially nested structure from the inside to the outside, and one end of the inner connecting pipe has the freedom to extend outward to the adjacent outer connecting pipe; one end of the outermost connecting pipe is connected to the fire extinguisher body 2; a set of transmission assemblies 23 is provided between each pair of adjacent connecting pipes, and the transmission assemblies 23 are used to drive one end of the corresponding inner connecting pipe to extend outward to the adjacent outer connecting pipe; wherein, the controller is electrically connected to the multiple sets of transmission assemblies 23 respectively, and the transmission assemblies 23 are used to drive the corresponding inner connecting pipe to extend and retract, so that the telescopic nozzle switches between an open state and a closed state.

[0058] It should be noted that the extension and retraction of the inner connecting tube is also controlled by the controller. Specifically, the controller is used to control the transmission component 23 to drive the corresponding inner connecting tube to extend and retract. The specific control elements and control principles of this part are all existing technologies and will not be described in detail here.

[0059] By setting the telescopic nozzle as a multi-stage inner and outer connecting pipe, on the one hand, it is beneficial to reduce the length of the nozzle 21 in the retracted state, thus facilitating the storage of the nozzle 21; on the other hand, it is beneficial to extend the multi-stage connecting pipe, thereby increasing the extension length of the nozzle 21, so that the nozzle outlet 22 is closer to the fire location; by setting the transmission component 23 and electrically connecting the transmission component 23 to the controller, the extension of the multi-stage connecting pipe can be automatically controlled, which is beneficial to improving the extension and retraction efficiency of the nozzle 21.

[0060] Optionally, the multi-stage connecting pipe is specifically two-stage, including a secondary connecting pipe 212 and a primary connecting pipe 211 that are sequentially connected from the inside out. One end of the primary connecting pipe 211 is connected to the fire extinguisher body 2. One end of the secondary connecting pipe 212 extends from the other end of the primary connecting pipe 211, and a set of transmission components 23 is provided between the primary connecting pipe 211 and the secondary connecting pipe 212. All transmission components 23 are electrically connected to the controller.

[0061] Optionally, the multi-stage connecting pipe is specifically three-stage, including a three-stage connecting pipe 213, a two-stage connecting pipe 212, and a one-stage connecting pipe 211, which are sequentially connected from the inside out. One end of the one-stage connecting pipe 211 is connected to the fire extinguisher body 2; one end of the two-stage connecting pipe 212 extends from the other end of the one-stage connecting pipe 211; and the three-stage connecting pipe 213 extends from inside the two-stage connecting pipe 212. A transmission assembly 23 is provided between the one-stage connecting pipe 211 and the two-stage connecting pipe 212, and another transmission assembly 23 is provided between the two-stage connecting pipe 212 and the three-stage connecting pipe 213. Each transmission assembly 23 is electrically connected to the controller.

[0062] Specifically, the number of stages in a multi-stage connecting pipe can be selectively set according to actual needs.

[0063] Please see Figure 4 For example, the transmission assembly 23 includes a first motor 231, a rotating gear 232, and a rack 233; the first motor 231 is fixed on the outer peripheral wall of the outer connecting tube; the power output shaft of the first motor 231 extends radially into the outer connecting tube; the rotating gear 232 is located at the extended end of the power output shaft; the rack 233 is fixed on the outer peripheral wall of the inner connecting tube and extends axially along the connecting tube; the rack 233 meshes with the rotating gear 232; wherein, the first motor 231 is electrically connected to the controller; the first motor 231 is used to drive the rotating gear 232 to rotate, so that the rotating gear 232 drives the rack 233 to move axially along the connecting tube.

[0064] The first motor 231 drives the rack 233 to move by rotating the gear 232, thereby causing the rack 233 to drive one end of the corresponding inner connecting tube to extend outward from the outer connecting tube, which is conducive to realizing the automatic extension of the inner connecting tube.

[0065] Specifically, the controller is used to control the start and stop of the first motor 231. The power output shaft of the first motor 231 drives the rotating gear 232 to rotate. The rotating gear 232 drives the rack 233 to move along the axial direction of the connecting pipe. Since the rack 233 is fixed on the inner connecting pipe, the rack 233 can drive the inner connecting pipe to move and extend.

[0066] It should be understood that the power output shaft of the first motor 231 extends into the outer connecting tube, which makes it easy to set the rotating gear 232 inside the outer connecting tube so that the rotating gear 232 and the rack 233 mesh.

[0067] It should be noted that the electrical connection method between the first motor 231 and the controller, as well as the control principle of the controller controlling the first motor 231, are existing technologies and will not be elaborated here.

[0068] Please see Figure 2 In some embodiments, a tearing plate 12 is provided at the outlet 11, and the telescopic end of the telescopic nozzle is used to break the corresponding tearing plate 12 to extend out of the fire extinguishing box 1.

[0069] By setting the tear plate 12, the inside of the fire extinguishing box 1 can be kept dustproof when not in use, and when in use, the spray pipe 21 can easily pass through the tear plate 12 to extend out of the fire extinguishing box 1.

[0070] Optionally, the tear plate 12 is made of a fragile material and is sealed at the outlet 11 to facilitate the extension of the telescopic nozzle by breaking the tear plate 12.

[0071] Optionally, the tear plate 12 and the fire extinguishing box 1 are an integral structure, and a groove is provided at the outlet 11 to reduce the thickness of the tear plate 12, thereby weakening the tear plate 12 so that the telescopic nozzle can break through the tear plate 12.

[0072] When an emergency requires the use of a telescopic nozzle, the tear plate 12 ensures that the nozzle can break through the obstacle and extend, thus extinguishing the fire source in a timely and effective manner, without delaying the fire extinguishing opportunity due to the nozzle's inability to extend.

[0073] Please see Figure 4 and Figure 5 In some possible embodiments, a first rotating shaft 24 is provided at the nozzle 22 of the spray pipe 21, and the first rotating shaft 24 extends radially along the spray pipe 21; one end of the first rotating shaft 24 extends out of the spray pipe 21 and is connected to a second motor 25; a first blade 26 is provided on the first rotating shaft 24; wherein, the second motor 25 is electrically connected to the controller; the second motor 25 is used to drive the first blade 26 to rotate around the first rotating shaft 24 to adjust the spray gap between the first blade 26 and the inner wall of the spray pipe 21.

[0074] In the initial state, the first blade 26 covers the nozzle 22, and the spray gap between the first blade 26 and the inner peripheral wall of the spray pipe 21 is zero or very small. The second motor 25 drives the first blade 26 to rotate around the first rotating shaft, so that the spray gap between the first blade 26 and the inner peripheral wall of the spray pipe 21 gradually increases. At the same time, the spray direction of the extinguishing agent in the circumferential direction of the first rotating shaft 24 can be adjusted.

[0075] It is important to understand that the rotation angle of the first blade 26 also affects the spray direction of the extinguishing agent. Therefore, the design of the first blade 26 provides an adjustable dimension for the spray of the extinguishing agent, which can flexibly adjust the spray range and direction of the extinguishing agent according to the fire situation and other conditions. By adjusting the spray gap, the accuracy of fire extinguishing can be improved, so that the extinguishing agent can act more accurately on the fire source and improve the fire extinguishing efficiency.

[0076] It should be understood that the controller is used to control the second motor 25 to drive the first blade 26 to rotate around the first rotating shaft 24, and the controller is used to control the third motor 28 to drive the second blade 29 to rotate around the second rotating shaft 27; and the control and driving principle of the controller for starting and stopping the second motor 25 and the third motor 28, as well as the specific electrical connection method, are all existing technologies and will not be elaborated here.

[0077] For example, the first blade 26 is circular in shape to match the shape of the nozzle 22.

[0078] Please see Figure 4 and Figure 6 In some embodiments, a second rotating shaft 27 is also provided at the nozzle 22 of the spray pipe 21, and the axis of the second rotating shaft 27 forms a preset angle with the axis of the first rotating shaft 24; one end of the second rotating shaft 27 extends out of the spray pipe 21 and is connected to a third motor 28; a second blade 29 is provided on the second rotating shaft 27; wherein, the third motor 28 is electrically connected to the controller; the third motor 28 is used to drive the second blade 29 to rotate around the second rotating shaft 27 in order to adjust the spray gap between the second blade 29 and the inner wall of the spray pipe 21.

[0079] For example, the second blade 29 is rectangular; alternatively, the second blade 29 is circular.

[0080] By further configuring the second blade 29, the spraying gap between the second blade 29 and the inner wall of the spray pipe 21 can be adjusted to further adjust the spraying direction of the extinguishing agent in the circumferential direction of the second rotating shaft 27, and further adjust the spray outlet 22 of the extinguishing agent.

[0081] Optionally, in the initial state, the first blade 26 covers the nozzle 22, and the second blade 29 is set perpendicular to the first blade 26. At this time, the axis of the second rotating shaft 27 is also set perpendicular to the first axis.

[0082] Specifically, the first rotating shaft 24 is set in the vertical direction. When the first blade 26 is rotated, the spray gap and spray angle of the nozzle 22 on the left and right sides of the first rotating shaft 24 can be adjusted. Since the second blade 29 is set perpendicular to the first blade 26 in the initial state, when the second blade 29 rotates around the second rotating shaft 27, the spray gap and spray angle on the upper and lower sides of the second rotating shaft 27 can be adjusted.

[0083] The first blade 26 and the second blade 29 work together to achieve the size of the spray gap and the spray angle of the extinguishing agent sprayed in two different dimensions.

[0084] Optionally, the first blade 26 and the second blade 29 are spaced apart along the axial direction of the connecting pipe; optionally, in the axial direction of the connecting pipe, the first blade 26 is positioned on the outer side of the second blade 29 near the nozzle 22; preferably, in the axial direction of the connecting pipe, the first blade 26 is positioned on the inner side of the second blade 29 away from the nozzle 22.

[0085] Please see Figure 3 In some possible embodiments, there are two outlets 11, which are symmetrically arranged along the left and right directions of the vehicle body; the fire extinguisher body 2 is provided with two sets of spray pipes 21, which are arranged one-to-one with the two outlets 11.

[0086] By symmetrically setting two outlets 11 and two sets of spray pipes 21, the extinguishing agent can be sprayed out in the left and right directions. When the fire is large, the extinguishing efficiency can be improved; when the fire is small and concentrated on one side, the spraying of the extinguishing agent can be more targeted, which is conducive to improving the extinguishing effect.

[0087] Since the sub-dashboard 3 is located in the middle of the vehicle compartment, by symmetrically arranging two spray pipes 21 on the left and right, fire extinguishing agent can be sprayed in both directions to extinguish the fire from both sides at the same time, expanding the fire extinguishing coverage area. Compared with the single-direction spraying method, it can more comprehensively cover the fire source area, greatly improve the fire extinguishing effect, and reduce the losses caused by the fire.

[0088] Please see Figure 1 and Figure 2 In some possible embodiments, the drive assembly 4 includes a guide rail assembly 41, multiple sets of drive wheels 42, and a fourth motor 43; the guide rail assembly 41 extends along the front-rear direction of the vehicle body and is disposed within the auxiliary instrument assembly and fixed to the vehicle floor; the multiple sets of drive wheels 42 are arrayed at the bottom of the fire extinguishing box 1 and placed within the guide rail assembly 41; the fourth motor 43 is disposed on the fire extinguishing box 1, and the output end of the fourth motor 43 is poweredly connected to one of the sets of drive wheels 42; the fourth motor 43 is electrically connected to the controller.

[0089] The controller is used to control the fourth motor 43 to drive the drive wheel 42 to rotate, thereby causing the fire extinguishing box 1 and the fire extinguisher body 2 to slide on the guide rail assembly 41 to achieve the extension of the fire extinguishing box 1; the guide rail assembly 41 is used to guide the sliding of the fire extinguishing box 1 to prevent the fire extinguishing box 1 from deviating during the movement.

[0090] With the guide rail assembly 41 and drive wheel 42, the fire extinguishing box 1 can be stably slid in the carriage, ensuring that it can be accurately slid into the carriage for fire extinguishing. The fourth motor 43 controls the fire extinguishing box 1 to be moved to the appropriate position quickly and accurately, improving the timeliness and effectiveness of fire extinguishing.

[0091] Specifically, the guide rail assembly 41 is provided with two guide rails arranged side by side along the left-right direction of the vehicle and extending along the front-back direction of the vehicle.

[0092] Preferably, the multiple sets of drive wheels 42 are specifically two sets, with each set of drive wheels 42 corresponding to one of the two guide rails. Each set of drive wheels 42 is tactilely connected to the corresponding guide rail to enable movement of the fire extinguishing box 1. Specifically, each set of drive wheels 42 has two wheels, spaced apart along the front-rear direction of the vehicle. Each drive wheel 42 corresponds to a fourth motor 43, and the drive wheel 42 is driven by controlling the activation of the fourth motor 43.

[0093] It should be understood that the control and driving principle of the controller for starting and stopping the fourth motor 43, as well as the specific electrical connection method, are all existing technologies and will not be elaborated here.

[0094] Based on the same inventive concept, this application also provides a vehicle including the above-mentioned vehicle-mounted sub-panel fire extinguishing device.

[0095] The vehicle provided in this application embodiment, having the aforementioned vehicle-mounted sub-panel fire extinguishing device, possesses all the beneficial effects of the aforementioned vehicle-mounted sub-panel fire extinguishing device. It is advantageous in maintaining the integrity and effectiveness of the fire extinguisher body 2 during a collision, and can effectively simplify the fire extinguishing operation process and improve fire extinguishing efficiency.

[0096] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
