All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without making any creative effort belong to the protection scope of the present application.

Example one

Referring to fig. 1, the vehicle fire extinguishing apparatus comprises a deformation body 1, a puncturing device 2 and a fire extinguishing bottle 3; the deformation body 1 is arranged on a vehicle, and the volume of the deformation body 1 becomes larger along with the increase of the temperature; the puncturing device 2 is arranged at one side of the deformation body 1, and in the process that the volume of the deformation body 1 is increased, the deformation body 1 pushes the puncturing device 2 to move to puncture the fire extinguishing bottle 3 so as to leak the fire extinguishing substances in the fire extinguishing bottle 3.

In this embodiment, the vehicle fire extinguishing apparatus may be provided on an engine hood of the vehicle, or may be provided in an engine compartment. The fire extinguishing substance in the fire extinguishing bottle 3 can be liquid or gas.

The fire extinguishing process of the vehicle fire extinguishing apparatus includes: when the external environment temperature increases, the volume of the deformation body 1 is increased, so that the deformation body 1 is promoted to extrude the puncture device 2 to push the puncture device 2 to move and puncture the fire extinguishing bottle 3, after the fire extinguishing bottle 3 is punctured by the puncture device 2, the fire extinguishing substances in the fire extinguishing bottle 3 leak from the fire extinguishing bottle 3, and the fire burning on the vehicle is extinguished.

Through the setting of vehicle extinguishing device, can utilize morphism 1 to automatically perceive the change of ambient temperature after the vehicle takes place the burning phenomenon and produces higher temperature to puncture fire-extinguishing bottle 3 when ambient temperature is too high, reach the purpose of putting out a fire. In the process, the puncture device 2 in the vehicle fire extinguishing device can automatically puncture the fire extinguishing bottle 3 without manually opening the fire extinguishing bottle 3 by passengers, so that the fire extinguishing efficiency is high; the fire extinguishing process does not need the participation of passengers, and the safety of the passengers is ensured to a certain extent.

In addition, in the conventional fire extinguishing apparatus for a vehicle, a temperature sensor is usually used to sense the temperature change, and a controller is used to control the fire extinguisher to be opened, but the temperature sensor and the controller are electronic products, which causes an insensitivity problem due to the temperature change. Based on the change of 1 volumes of morphism body in this application, come the setting that extrudes puncture device 2 and remove puncture fire-extinguishing bottle 3, cancelled and utilized temperature sensor to come the mode of discerning the temperature among the traditional vehicle extinguishing device, purely adopt physical structure to realize putting out a fire, can not appear the condition that sensitivity reduces because of ambient temperature changes.

Moreover, this application vehicle extinguishing device's simple structure, the preparation material is comparatively cheap, and manufacturing cost is compared in traditional vehicle extinguishing device and is lower.

In this embodiment, the fire extinguishing apparatus for a vehicle includes the deformation body 1, the puncture device 2, and the fire extinguishing bottle 3, which are sequentially disposed, and the deformation body 1, the puncture device 2, and the fire extinguishing bottle 3 are located on the same straight line, and these three structures will be explained in detail below.

The structure of the modification 1 may include: the deformation body 1 is provided on one side of the piercing means 2. In order to ensure that the deformation body 1 can push the puncture device 2 immediately after being deformed, the distance between the deformation body 1 and the puncture device 2 can be set to be relatively small, so that the deformation body 1 can be in contact with the puncture device 2 by a small moving distance to press the puncture device 2 after being deformed. The deformation body 1 can be made of foaming materials such as EVA and AES, the volume of the deformation body 1 is increased under the condition that the volume is higher than a preset temperature value, and the preset temperature value is higher than the temperature in an engine cabin when a vehicle is normally used.

For example, when the vehicle is in normal use, the preset temperature value of the deformation body 1 can be 160 ℃ because the temperature in the engine compartment of the vehicle is less than or equal to 130 ℃, the volume of the deformation body 1 can be increased when the ambient temperature around the deformation body 1 is higher than 160 ℃, and the volume of the deformation body 1 is not changed when the temperature is lower than 160 ℃.

Correspondingly, when the vehicle runs, the temperature in the cabin is less than or equal to 130 ℃ and does not reach the deformation temperature of the deformation body 1, so the deformation body 1 is solid under the condition that the vehicle normally runs, and the volume cannot be increased; after a fire occurs in the vehicle, the deformation temperature of 1160 ℃ of the deformation body is reached, so that the deformation body 1 becomes an expanded and fluffy object under the condition that the vehicle has a fire, and the puncture device 2 is squeezed to move so as to puncture the fire extinguishing bottle 3.

Through the setting of morphism body 1, can replace the temperature sensor among the traditional vehicle extinguishing device to carry out the perception to the temperature to after the temperature reaches preset temperature value, promote puncturing device 2 and puncture fire-extinguishing bottle 3. Since the modification 1 is a physical structure and is not an electronic product, it is not affected by the external environment temperature to lower the sensitivity.

The structure of the lancing device 2 may include: a pushing part 21 and a spine part 22; the pushing portion 21 is opposite to the deformation body 1; the spine part 22 is opposite to the fire extinguishing bottle 3; the pushing portion 21 pushes the sharp-pointed portion 22 to pierce the fire-extinguishing bottle 3 under the compression of the deformation body 1.

Wherein, promotion portion 21 sets up in the position that is close to morphism 1, and spine portion 22 is many piercing stems that have a tip, and the one end of many piercing stems deviates from morphism 1 one side mutually perpendicular with promotion portion 21, and the other end of many piercing stems is towards fire-extinguishing bottle 3 for pierce fire-extinguishing bottle 3.

Specifically, after the size of the deformation body 1 is increased, the pushing portion 21 is pressed to move towards the direction close to the fire extinguishing bottle 3, and the pushing portion 21 drives the spike portion 22 connected with the pushing portion to move towards the direction close to the fire extinguishing bottle 3, so as to puncture the fire extinguishing bottle 3.

The structure of the fire-extinguishing bottle 3 may include: the fire extinguishing bottle 3 is provided with an air leakage opening 31; an anti-leakage plate 4 is hermetically arranged on the air leakage port 31, and the anti-leakage plate 4 is opposite to the puncture device 2; the puncture device 2 punctures the anti-leakage plate 4 under the pushing of the deformation body 1, so that the fire extinguishing substance in the fire extinguishing bottle 3 leaks from the punctured gap of the anti-leakage plate 4.

Wherein, the air escape opening 31 is opposite to the spine portion 22, and the anti-leakage plate 4 on the air escape opening 31 can be made of foam material, and becomes more fluffy along with the rise of temperature, and the deformation temperature of the anti-leakage plate 4 can be consistent with the deformation temperature of the deformation body 1, namely, the volume can be increased when the temperature reaches 160 ℃ and becomes more fluffy.

For example, when the vehicle is running, since the temperature in the cabin is less than or equal to 130 ℃ and does not reach the deformation temperature of the deformation body 1 and the leakage-proof plate 4, the deformation body 1 and the leakage-proof plate 4 are solid under the condition that the vehicle is running normally, and the volume cannot be increased; after a fire disaster occurs to the vehicle, the deformation temperature of the deformation body 1160 ℃ is reached, so the deformation body 1 and the anti-leakage plate 4 become expanded to be a fluffy object under the condition that the vehicle is in the fire disaster, the deformation body 1 extrudes the puncture device 2 to move towards the direction close to the anti-leakage plate 4 after being deformed, and the anti-leakage plate 4 is changed to be the fluffy object after being deformed, so that the puncture device 2 can puncture conveniently.

By arranging the anti-leakage plate 4 as a foaming material, the anti-leakage plate 4 can be converted from a solid to a fluffy object when the external temperature is higher than a preset temperature value, so that the puncture device 2 can puncture the anti-leakage plate conveniently, and the fire extinguishing substances in the fire extinguishing bottle 3 can be leaked out more easily; when the external temperature is lower than the preset temperature value, the anti-leakage plate 4 is solid, and even if the puncture device 2 is shaken by the outside and touches the anti-leakage plate 4, the anti-leakage plate 4 cannot be punctured.

In this embodiment, in order to integrate the fire-extinguishing bottle 3, the puncturing device 2 and the deforming body 1 into the same device, the fire-extinguishing bottle further comprises a housing 5, the deforming body 1, the puncturing device 2 and the fire-extinguishing bottle 3 are sequentially arranged in the housing 5, a plurality of air leakage holes (not shown in the figure) are arranged on the housing 5, and accordingly, the housing 5 may be a hollow structure.

Illustratively, after the anti-leakage plate 4 on the fire-extinguishing bottle 3 is punctured by the puncturing device 2, the fire-extinguishing substances leaked from the interior of the fire-extinguishing bottle 3 are discharged from the plurality of air-release holes on the housing 5 and are discharged into the engine compartment, so as to extinguish the fire in the engine compartment.

By the arrangement of the shell 5, the fire extinguishing bottle 3, the puncture device 2 and the deformation body 1 can be integrated into the shell 5, thereby facilitating the installation of the whole vehicle fire extinguishing device; and, through the setting of a plurality of bleeder holes on the fire bottle 3, can discharge the fire extinguishing substance who leaks to in the casing 5 to the engine cabin to put out the intensity of a fire in the engine cabin.

The housing 5 may be made of a heat-resistant and pressure-resistant material, and specifically, may be made of metal or a material having relatively strong heat resistance and bearing capacity.

In addition, a guide block can be arranged on the puncturing device 2, and a guide groove matched with the guide block is arranged on the inner wall of the shell 5; the guide block moves along the guide groove to move the puncturing device 2 in the direction of the guide groove when the puncturing device 2 is pushed by the deforming body 1.

Specifically, the guide block may be disposed on the pushing portion 21, the guide groove may be disposed on an inner wall of the housing 5, and the guide groove is disposed along a length direction of the housing 5.

When the pushing portion 21 is pressed by the deformation body 1 to move, the guide block moves along the guide groove, and plays a role in guiding the moving direction of the pushing portion 21, so that the sharp piercing portion 22 on the pushing portion 21 is guided to the leakage-proof plate 4 to pierce the leakage-proof plate 4.

Through the setting of guide block and guide way, can play the guide effect to the moving direction of promotion portion 21, avoid promotion portion 21 can't remove to the position of aliging with preventing leaking board 4

In order to avoid the guide groove blocking the expansion and expansion of the deformation body 1, the opening edge of the guide groove is arranged to be flush with the inner side wall of the shell 5, so that the deformation body 1 can continue to expand and expand above the guide groove.
