[0026] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

[0028] Unless otherwise specifically stated, the relative arrangement of the parts and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the accompanying drawings are not drawn according to actual proportional relationships. The technology, methods and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be considered as a part of the specification. In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of the exemplary embodiments can have different values. It should be noted that similar numbers and letters represent similar items in the following drawings, and therefore, once an item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0029] In this embodiment, if Figures 1 to 5 As shown, the fire extinguishing device includes: a vehicle body 1, wheels 2, a first lifting member 8, a fire-fighting assembly, a second lifting member 701, a support leg 702, and a rotating rod 602. A mounting cavity is provided in the vehicle body 1. The wheel 2 is rotatably provided on the vehicle body 1. The first lifting member 8 is rotatably provided in the mounting cavity. The fire-fighting assembly is provided on the first lifting member 8, and the fire-fighting assembly is lifted and lowered to have a working position extending outside the mounting cavity and a storage position located inside the mounting cavity. The second lifting member 701 is rotatably provided in the mounting cavity, and the movement direction of the second lifting member 701 is opposite to that of the first lifting member 8. The support leg 702 is provided on the second lifting member 701, and the support leg 702 is lifted and lowered to have a supporting position extending outside the mounting cavity and a retracted position located inside the mounting cavity. The rotating rod 602 is rotatably provided in the mounting cavity, and the rotating rod 602 rotates to drive the first lifting member 8 and the second lifting member 701 to move in opposite directions.

[0030] In this way, when the firefighting assembly is needed, the rotating rod 602 can be driven to rotate, causing the first lifting member 8 and the second lifting member 701 to move away from each other. The first lifting member 8 causes the firefighting assembly to rise and switch to its working position, extending outside the installation cavity, to facilitate firefighting operations. At this time, the second lifting member 701 drives the legs 702 to switch to a supporting position extending outside the installation cavity, so that the legs 702 can support the vehicle body 1, ensuring that the firefighting assembly is more firmly and reliably supported on the ground during firefighting operations. When the firefighting assembly is no longer needed, the rotating rod 602 can be driven to rotate, causing the first lifting member 8 and the second lifting member 701 to move away from each other, causing the first lifting member 8 to lower the firefighting assembly and switch to its storage position within the installation cavity. This reduces the impact of temperature and humidity fluctuations and dust in the equipment room on the firefighting assembly, thereby reducing the impact on the firefighting assembly's performance. Furthermore, the second lifting member 701 drives the legs 702 to switch to a retracted position within the installation cavity, facilitating the movement of the vehicle body 1. Therefore, the technical solution of this application effectively solves the problem in related art where the firefighting assembly is exposed to the environment of the equipment room, which can easily affect its performance. Furthermore, by using the rotating rod 602 to synchronously drive the first lifting member 8 and the second lifting member 701 to move in opposite directions, operation is faster, firefighting efficiency is improved, and the structure of the firefighting device is more compact.

[0031] In this embodiment, the movement of the vehicle body 1 can be remotely controlled via a remote controller, making it easier to freely move the vehicle body 1. Two legs 702 are spaced apart on the second lifting member 701, and the legs 702 extend vertically. When the firefighting component is performing a fire extinguishing operation, the firefighting component needs to spray fire extinguishing agent, which will generate a recoil force on the vehicle body 1. The legs 702 support the vehicle body 1, allowing the vehicle body 1 to be more firmly and reliably supported on the ground when subjected to a recoil force, thereby reducing the tilting or movement of the vehicle body 1 after the recoil force. Furthermore, the arrangement of the wheels 2 facilitates the movement of the vehicle body 1.

[0032] In this embodiment, the fire-fighting component is a fire extinguisher.

[0033] like Figures 1 to 5As shown, the vehicle body 1 is provided with an opening connected to the installation cavity, and the fire extinguishing device also includes a flap 4 and a transmission structure 9. The flap 4 is swingably provided at the opening, and has an open position that avoids the opening and a covering position that covers the opening. The transmission structure 9 is connected between the flap 4 and the first lifting member 8. The first lifting member 8 is raised and lowered to drive the flap 4 to switch between the open position and the covering position through the transmission structure 9. The fire extinguishing device is provided with an opening and a swingable flap 4 on the vehicle body 1, and is used in conjunction with the transmission structure 9, so that the fire-fighting component can extend from the opening to the outside of the vehicle body 1 when switched to the working position. When the fire-fighting component is in the storage position, the opening is covered by the flap 4, which improves the sealing of the installation cavity, protects the fire-fighting component from dust and changes in temperature and humidity, and reduces the impact on the performance of the fire-fighting component. The setting of the transmission structure 9 can drive the flap 4 to switch between the open position and the covering position when the first lifting member 8 is raised and lowered, thereby improving efficiency.

[0034] like Figures 1 to 5 As shown, the transmission structure 9 includes a first transmission member 902 and a second transmission member 901. The first end of the first transmission member 902 is fixedly connected to the first lifting member 8, the second end of the first transmission member 902 is hinged to the first end of the second transmission member 901, and the second end of the second transmission member 901 is hinged to the flap 4. The hinged design of the first and second transmission members 902 and 901 enables the flap 4 to swing in accordance with the lifting and lowering of the first lifting member 8, reducing the problem of the flap 4 jamming during swinging and making the flap 4 swing more smoothly. By connecting the first transmission member 902 between the first lifting member 8 and the second transmission member 901, the flap 4 is automatically opened and closed, ensuring smooth operation of the firefighting assembly and effective protection in the non-operating state. It is a key component in the transmission structure 9 for automatically controlling the flap 4. The provision of the first transmission member 902 can effectively adjust the swing range of the flap 4, making the linkage between the first lifting member 8 and the flap 4 more accurate.

[0035] like Figures 1 to 5 As shown, the transmission structure 9 also includes a first fixed shaft 903 provided on the second end of the first transmission member 902, and a mounting hole is provided on the first end of the second transmission member 901, and the first fixed shaft 903 is inserted into the mounting hole. The provision of the first fixed shaft 903 and the mounting hole makes the hinged operation of the first transmission member 902 and the first fixed shaft 903 more convenient and quick. A guide groove 904 is provided on the inner side wall of the vehicle body 1, and the first transmission member 902 is movably provided in the guide groove 904 and cooperates with the guide of the guide groove 904. The guiding cooperation between the guide groove 904 on the inner side wall of the vehicle body 1 and the first transmission member 902 improves the smooth movement of the first transmission member 902, thereby ensuring the stability and accuracy of the transmission structure 9 when driving the flap 4 to move, avoiding the shaking of the flap 4 caused by the instability of the transmission structure 9, and improving the reliability of the fire extinguishing device when in use.

[0036] In other embodiments, the transmission structure 9 further includes a first fixed shaft 903 disposed on the second end of the first transmission member 902. The first end of the second transmission member 901 is provided with a mounting hole, and the first fixed shaft 903 is inserted into the mounting hole. Alternatively, a guide groove 904 is provided on the inner side wall of the vehicle body 1, and the first transmission member 902 is movably disposed in the guide groove 904 and guided by the guide groove 904.

[0037] like Figures 1 to 6 As shown, the fire extinguishing device also includes a mounting block 1301 connected to the vehicle body 1 and a second fixed shaft 1302 arranged on the mounting block 1301. A socket is provided on the flap 4, and the second fixed shaft 1302 is inserted into the socket. The setting of the mounting block 1301 facilitates the installation of the second fixed shaft 1302. The cooperation between the second fixed shaft 1302 and the socket facilitates the swingable setting of the flap 4 on the vehicle body 1, thereby improving assembly efficiency. A hinge seat 905 is provided on the flap 4, and the second end of the second transmission member 901 is hinged to the hinge seat 905. The hinged connection between the hinge seat 905 on the flap 4 and the second transmission member 901 makes the hinged operation of the flap 4 and the second transmission member 901 more flexible, and also makes the opening and closing of the flap 4 smoother, while ensuring the tightness of the flap 4 when covering the opening, effectively preventing dust from entering.

[0038] In other embodiments, the fire extinguishing device further includes a mounting block 1301 connected to the vehicle body 1 and a second fixed shaft 1302 disposed on the mounting block 1301. The flap 4 is provided with a socket into which the second fixed shaft 1302 is inserted. Alternatively, the flap 4 is provided with a hinge seat 905, and the second end of the second transmission member 901 is hingedly connected to the hinge seat 905.

[0039] like Figures 1 to 5 As shown, the rotating rod 602 extends vertically and is provided with a first threaded segment and a second threaded segment with a rotation direction opposite to the first threaded segment. The first lifting member 8 is provided with a first threaded hole that threadably engages with the first threaded segment, and the second lifting member 701 is provided with a second threaded hole that threadably engages with the second threaded segment. The cooperation between the first threaded segment on the rotating rod 602 and the first threaded hole of the first lifting member 8, and the cooperation between the second threaded segment on the rotating rod 602 and the second threaded hole of the second lifting member 701, achieves the synchronous movement of the firefighting assembly and the support leg 702. When the rotating rod 602 rotates, it can simultaneously drive the firefighting assembly and the support leg 702 toward or away from each other, thereby improving transmission efficiency and enhancing the operational convenience and safety of the fire extinguishing device. The fire extinguishing device also includes a motor 601 disposed within the mounting cavity, which drives the rotating rod 602 to rotate. The provision of the motor 601 facilitates the drive of the rotating rod 602, improving the operational convenience of the fire extinguishing device.

[0040] In this embodiment, the pitch of the first thread segment is greater than the pitch of the second thread segment, and the number of thread turns of the first thread segment is the same as the number of thread turns of the second thread segment. This allows the first lifting member 8 to move a greater distance with each rotation of the rotating rod 602, allowing the firefighting assembly to switch between the working position and the storage position more quickly. This arrangement also facilitates the first lifting member 8 to move the firefighting assembly to the working position while simultaneously switching the support legs 702 to the support position when the rotating rod 602 rotates.

[0041] In other embodiments, the rotating rod 602 extends vertically and is provided with a first threaded segment and a second threaded segment having a rotation direction opposite to the first threaded segment. The first lifting member 8 is provided with a first threaded hole that threadably engages with the first threaded segment, and the second lifting member 701 is provided with a second threaded hole that threadably engages with the second threaded segment. Alternatively, the fire extinguishing device further includes a motor 601 disposed within the mounting cavity, which drives the rotating rod 602 to rotate.

[0042] like Figures 1 to 5 As shown, the fire extinguishing device also includes a guide rod 14 arranged in the installation cavity, and the first lifting member 8 is provided with a first guide hole that can be guided and matched with the guide rod 14. The second lifting member 701 is provided with a second guide hole that can be guided and matched with the guide rod 14. The guiding cooperation between the guide rod 14 and the first guide hole of the first lifting member 8 improves the smoothness and accuracy of the first lifting member 8 during lifting. The guiding cooperation between the guide rod 14 and the second guide hole of the second lifting member 701 improves the smoothness and accuracy of the second lifting member 701 during lifting. The deviation or shaking of the first lifting member 8 and the second lifting member 701 during the lifting process is reduced, thereby improving the mechanical stability of the fire extinguishing device and the working accuracy of the fire fighting component.

[0043] In this embodiment, two guide rods 14 are spaced apart. The first lifting member 8 is provided with two first guide holes, which correspond to and guide the two guide rods 14 in a one-to-one manner. The second lifting member 701 is provided with two second guide holes, which correspond to and guide the two guide rods 14 in a one-to-one manner.

[0044] In other embodiments, the fire extinguishing device further includes a guide rod 14 disposed in the mounting cavity, and the first lifting member 8 is provided with a first guide hole capable of guiding and cooperating with the guide rod 14. Alternatively, the second lifting member 701 is provided with a second guide hole capable of guiding and cooperating with the guide rod 14.

[0045] like Figures 1 to 5As shown, the fire extinguishing device also includes a telescopic rod 10 and a nozzle assembly 12. The telescopic rod 10 is telescopically disposed within the mounting cavity, and the nozzle assembly 12 is disposed at the telescopic end of the telescopic rod 10. The telescopic rod 10 is extended to drive the nozzle assembly 12 out of the mounting cavity. The arrangement of the telescopic rod 10 allows the nozzle assembly 12 to be stored within the mounting cavity when not in use, reducing the impact of dust in the equipment room on the nozzle, extending the service life of the nozzle assembly 12, and reducing the maintenance cost of the fire extinguishing device. Furthermore, the telescopic rod 10 can drive the nozzle assembly 12 to rise and fall, thereby increasing the spray range and improving fire extinguishing efficiency.

[0046] In this embodiment, the telescopic rod 10 is an electric telescopic rod. A support truncated platform 11 is further provided on the telescopic end of the telescopic rod 10, and a nozzle assembly 12 is fixedly provided on the support truncated platform 11. The nozzle assembly 12 includes a plurality of fire extinguishing nozzles.

[0047] like Figures 1 to 5 As shown, the fire extinguishing device also includes a telescopic conduit 15 connecting the firefighting assembly and the nozzle assembly 12. The telescopic conduit 15 has a spiral stretching section that has a stretched state (extended) and a shortened state when not subject to external forces. The design of the telescopic conduit 15 and the spiral stretching section ensures that the pipe connection between the firefighting assembly and the nozzle assembly 12 remains stable during the raising and lowering of the firefighting assembly, without affecting the spraying effect due to stretching or compression. At the same time, the firefighting assembly can naturally shorten when it is in the stowed position, reducing the internal space occupied by the installation cavity, optimizing the wiring within the installation cavity, and improving the compactness and operational convenience of the fire extinguishing device.

[0048] In this embodiment, the spiral stretching section includes a stretching tube and an elastic member provided on the stretching tube. The elastic member can be stretched when subjected to an external force, and is in a naturally shortened state when not subjected to an external force.

[0049] like Figures 1 to 5 As shown, the fire extinguishing device also includes a support base 703 provided at the bottom of the support leg 702. The provision of the support base 703 improves the support stability of the support leg 702 when in the supporting position, and increases the stability of the fire extinguishing device when in use. The fire extinguishing device also includes a detector 3 and a controller provided on the vehicle body 1. The detector 3 is signal-connected to the controller, and the controller is control-connected to the rotating rod 602. The coordinated use of the detector 3 and the controller enables the fire extinguishing device to automatically detect fires and respond quickly. The detector 3 transmits the fire signal to the controller, and the controller controls the rotating rod 602 to rotate, so that the rotating rod 602 can drive the first lifting member 8 and the fire-fighting assembly to rise, and the fire-fighting assembly switches to a working position extending outside the mounting cavity to perform fire-fighting operations, thereby realizing automated firefighting and improving the timeliness and accuracy of fire response.

[0050] In other embodiments, the fire extinguishing device further includes a support base 703 provided at the bottom of the support leg 702. Alternatively, the fire extinguishing device further includes a detector 3 and a controller provided on the vehicle body 1, the detector 3 being signal-connected to the controller, and the controller being control-connected to the rotating rod 602.

[0051] In the description of the present invention, it is to be understood that "plurality" refers to a quantity of two or more than two. The directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise stated, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside" and "outside" refer to the inside and outside relative to the outline of each component itself.

[0052] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.
