Description

Technical Field

[0001] The present invention relates to a fire blanket for a vehicle, and in particular to a fire blanket lowering mechanism which is usually hung with a fire blanket and can allow the fire blanket to fall and completely cover the vehicle when the vehicle is on fire. Background Art

[0002] Traditionally, if an electric vehicle powered by electricity catches fire in a driving accident, compared to previous fuel vehicles, electric vehicles require a lot of water to extinguish the fire. For example, in the electric vehicle fire in California, firefighters used 6,000 gallons of water to put out the fire, which is equivalent to the amount of water used to put out a building fire. In another electric vehicle fire in Houston, a total of eight firefighters took 7 hours to put out the fire, and according to statistics, 106 tons of water were used, which is equivalent to the department's water consumption for one month. In comparison, fuel vehicle fires can usually be put out with more than 1 ton of water, which is equivalent to the water capacity of a fire truck. The reason why electric vehicle fires are difficult to extinguish is that the battery pack of an electric vehicle is composed of multiple lithium-ion batteries. When the electric vehicle battery is defective or damaged, it may cause the lithium-ion battery to short-circuit, thereby causing the battery to heat up and the thin film that separates the cathode and anode of the battery structure to melt. Once a fire occurs, it will trigger a "thermal runaway" phenomenon, and the fire will burn for several hours until the chemical substances in the battery are burned out. Therefore, even if the fire is extinguished in a short time, the fire will continue to recur.

[0003] To solve this problem, people have tried to smother the fire and let the electric car burn slowly instead of extinguishing it. The specific method is to completely cover the burning electric car with a fire blanket (or fire extinguishing blanket) made of fiberglass. In addition to lowering the surrounding temperature and reducing smoke generation, the special coating of the fire blanket can also inhibit toxic substances from overflowing the fire blanket and prevent toxic substances from spreading to the surrounding area.

[0004] However, the traditional fire blanket is covered by manpower, more specifically, two people pull up the opposite sides of the fire blanket respectively, pass along the opposite sides of the burning electric vehicle, so that the fire blanket passes over the roof of the electric vehicle and completely covers the vehicle body to ensure that the burning harmful substances or high temperature will not affect the surroundings. However, the fire blanket is heavy. A fire blanket suitable for ordinary bicycles weighs 25 to 30 kilograms. Therefore, it usually takes an adult to pull up the fire blanket. When covering the electric vehicle with the fire blanket, the person responsible for pulling the fire blanket needs to get close to the burning electric vehicle and pass from both sides of the electric vehicle. Considering the high temperature and flames of the burning electric vehicle, the risk is self-evident. In the parking lot, vehicles are often parked side by side according to the division of parking spaces, or there are often neighboring vehicles or pillars around the vehicle, so that the space beside the vehicle is only tens of centimeters wide. It is difficult for one person to pass through it normally. When the vehicle catches fire, the flames can extend to more than one meter. At this time, it is extremely dangerous for a living person to pull the heavy fire blanket through the flames, or even impossible to pass through. In addition, if the fire blanket is hastily covered without confirming whether the fire blanket completely covers the vehicle, the effect of the fire blanket in blocking high temperatures and toxic substances will be extremely limited.

[0005] Furthermore, although designs for deploying fire blankets mechanically are commonly seen, the principle is that a mechanism simulates two people pulling the fire blanket at the same time and deploying it in a planar extension manner (for example, Chinese invention application CN115430080). Although this can avoid the danger of people approaching the fire source, this design ignores the fact that the car is a three-dimensional structure, resulting in the fire blanket being unable to fully cover the car. Specifically, if a cloth curtain is to be used to completely cover both sides of the vehicle body, the width of the cloth must be at least the width of the roof plus twice the height of the vehicle. The height of a family car on the market is usually more than 145 cm, and the width of the roof is usually more than 120 cm. Taking the size of the family car as an example, a cloth of at least 410 cm in width is required to completely cover both sides of the vehicle body. However, the width of a parking space in a parking lot is usually no more than 300 cm. In addition, the fire blanket deployment mechanism in the market is designed so that the width of the fire blanket does not exceed the width of the parking space. Therefore, the maximum width of the fire blanket is 300 cm. When the fire blanket covers the family car from the roof down, the length of the fire blanket hanging down on both sides can only cover the position of the door handles. The fire in the electric vehicle is located at the battery on the chassis, which cannot be covered by the fire blanket at all. Therefore, it is impossible to achieve the effect of completely covering the electric vehicle.

[0006] If the width of the machine is designed to be more than 410 cm, it is still difficult to achieve the effect of suppressing the fire, because if the width of the fire blanket exceeds the width of the parking space, when the fire blanket falls, it will fall on the roof of the adjacent car, resulting in a gap between the fire blanket and the ground, and it cannot completely cover both sides of the car body, and the effectiveness is also not high. In addition, the above-mentioned mechanical fire blanket design has a complex structure and high cost, which is not conducive to large-scale promotion. In summary, although electric vehicle fires can be suppressed with fire blankets, the use of fire blankets is dangerous, especially in indoor parking lots. The space beside the car is small because of adjacent cars or pillars. At this time, it is quite difficult to completely cover the electric car that has caught fire with a fire blanket. It is difficult to properly apply fire blankets whether by manpower or existing mechanical designs. Therefore, there is still room for improvement.

[0007] In view of this, how to improve the above problems is the primary issue that the present invention aims to solve. Summary of the invention

[0008] The main purpose of the present invention is to provide a fire blanket lowering mechanism, which can pull the fire blanket to cover the electric vehicle on fire by pulling the pulling member. In addition to preventing the person pulling the fire blanket from getting close to the fire source and getting burned, it can also ensure that the fire blanket completely covers the side of the electric vehicle.

[0009] To achieve the above-mentioned purpose, the present invention provides a fire blanket dropping mechanism, which can be used with a vehicle body. The fire blanket dropping mechanism includes:

[0010] A body, comprising at least four supporting points, the four supporting points mutually forming an imaginary horizontal shielding surface along a direction perpendicular to the ground, the area of ​​the horizontal shielding surface being larger than the maximum horizontal cross-sectional area of ​​the body, the four supporting points being arranged at opposite front and rear sides of the body and being two front supporting points and two rear supporting points symmetrically arranged respectively;

[0011] Two support members are respectively connected between each front support point and each rear support point located on the same side of the vehicle body, and the two support members are located on opposite left and right sides of the vehicle body, wherein each support member has a first end and a second end, each first end is supported by the two front support points, and each second end is supported by the two rear support points;

[0012] a fire blanket, hung on the two supporting members and foldable at a position close to the first ends of the two supporting members at ordinary times, the fire blanket having a front side formed toward the two front supporting points, and a rear side formed toward the two rear supporting points, when the fire blanket is unfolded, the rear side slides along the supporting members toward the rear supporting points and relatively away from the front side, the width of the fire blanket is greater than the width of the horizontal shielding surface, so that the opposite sides of the fire blanket respectively hang down outwards on the outside of each supporting member to form a hanging portion respectively;

[0013] At least one pulling member connected to the rear side of the fire blanket, the pulling member can be pulled to make the rear side of the fire blanket unfold along the two supporting members in the direction of the two rear supporting points; and

[0014] At least one positioning control component, when the pulling member pulls the rear side of the fire blanket toward the two rear supporting points and the fire blanket is unfolded to an area that can completely cover the vehicle body, the positioning control component controls the two supporting members to release their own supporting force, causing the fire blanket to fall due to loss of support.

[0015] Preferably, two detachable parts are provided, which are respectively provided at the first end of each support member, and each support member is connected to each front supporting point through each detachable part. The fire blanket is supported by each support member and suspended in the air. Each detachable part can be separated due to being pulled. When each detachable part is separated, the first end of each support member is separated from each front supporting point, so that each support member releases its own supporting force due to the falling of the first end, and then the fire blanket falls down due to its own weight due to the loss of support.

[0016] Furthermore, in one embodiment, each of the aforementioned detachable parts is respectively composed of a quick-release buckle and is arranged between the first end of each support member and each front fulcrum, and each support member is formed with a ring portion at the second end, and each rear fulcrum is provided with a hook member with an opening facing downward on the side facing each support member, and each support member is respectively connected to the hook member of each rear fulcrum by the ring portion. When the buckle of each detachable part is pulled and separated, the first end of each support member falls down due to separation from the front fulcrum, and the second end of each support member loses tension, causing each ring portion to slide from the opening of each hook member due to its own weight.

[0017] In another embodiment, each support member is made of soft material and can be deformed at will, and the second end of the support member is fixed on the rear support point. When the first end of the support member is separated from the front support point, the second end of the support member sags due to gravity, causing the fire blanket to slide down.

[0018] Preferably, two buckles are provided on opposite sides of the rear side of the fire blanket, and the two buckles are slidably mounted on each support member, respectively. When each buckle is pulled, the fire blanket can be unfolded or folded as the buckle slides, and the positioning control component includes two positioning nodes, each positioning node is provided on each support member and is relatively close to the second end. When each buckle slides along each support member and the fire blanket is unfolded to cover the vehicle body, each buckle abuts against the two positioning nodes. The two positioning nodes are spherical and have an outer diameter larger than the inner diameter of the two buckles, so that the two buckles cannot pass through the positions set by each positioning node. When the pulling member pulls the rear side of the fire blanket in the direction of the two rear fulcrums and the two buckles have abutted against the two positioning nodes, since each buckle is abutted by the positioning nodes, the pulling force applied to the fire blanket by the pulling member is transmitted to each support member. When the pulling force continues to act until the separable parts are pulled apart, the support members fall down together with the fire blanket.

[0019] Preferably, the height of the two front supporting points is lower than that of the two rear supporting points, so that the two supporting members are inclined in the same direction, and the fire blanket is hung on the first ends of the two supporting members when folded, so that the fire blanket will not slide by itself and obstruct the sight of the parking space.

[0020] Preferably, a detection device is further provided. When the detection device detects a fire, a warning signal is issued to cause the pulling member to be pulled by manpower or an automated mechanism to unfold the fire blanket.

[0021] Preferably, each front support point and each rear support point are respectively connected to a fence below each support member. When the fire blanket is hung on the two support members, the two hanging parts hang down from the outside of the two support members and then are collected in the range surrounded by the two fences, so as to prevent the fire blanket from falling onto the roof of the neighboring car or other obstacles when falling, and failing to completely cover the car body originally set to be protected.

[0022] Preferably, a roller structure is provided at the bottom of the seat body so that the seat body can slide and move horizontally.

[0023] Preferably, the bottom of the seat body has a U-shaped frame and a movable frame, the U-shaped frame has a notch, the movable frame can be slidably disposed in the U-shaped frame, and can move forward and backward relative to the U-shaped frame through the notch, the two front fulcrums are disposed on the top surface of the U-shaped frame, and the two rear fulcrums are disposed on the top surface of the movable frame, when the movable frame approaches or moves away from the U-shaped frame, the two rear fulcrums synchronously approach or move away from the two front fulcrums.

[0024] Preferably, a pulley is provided on the seat body so that the pulling member can be pulled from different directions and drive the fire blanket to unfold.

[0025] Preferably, each support member is composed of a telescopic tube.

[0026] Beneficial effects of the present invention: The fire blanket lowering mechanism of the present invention can pull the fire blanket to cover the electric vehicle on fire by pulling the pulling piece. In addition to preventing the person pulling the wire from getting close to the fire source and getting burned, it can also ensure that the fire blanket completely covers the side of the electric vehicle.

[0064] See also Figures 1 to 3 , shown is the first embodiment of the fire blanket dropping mechanism provided by the present invention, which will be described in conjunction with an electric vehicle. It is worth mentioning that since the fire blanket dropping mechanism of the present invention can also be applied to fuel vehicles, the fire can be slowed down by covering the fuel vehicle with a fire blanket, thereby isolating the oxygen flow. Therefore, the following description will be generally described with a vehicle body C without being limited to the type of vehicle. In addition, all descriptive words that contain directional indications, such as: front, rear, etc., are described with the vehicle body C facing direction as an example of the front side.

[0065] The first embodiment of the fire blanket lowering mechanism of the present invention comprises a base 1, two supporting members 2, a fire blanket 3, at least one pulling member 4, two detachable members 5 and at least one positioning control component 6, wherein:

[0066] The seat body 1 can be set on the ceiling or the ground. In this embodiment, the seat body 1 is mounted on the ceiling. The seat body 1 includes at least four fulcrums. The four fulcrums are set on the front and rear sides of the vehicle body C and respectively form two front fulcrums 11 and two rear fulcrums 12 that are symmetrically set. Each front fulcrum 11 is located on the front side of the vehicle body C, and each rear fulcrum 12 is located on the rear side of the vehicle body C. The four fulcrums form an imaginary horizontal shielding surface P along the direction perpendicular to the ground, and the area of ​​the horizontal shielding surface P is larger than the maximum horizontal cross-sectional area of ​​the vehicle body C.

[0067] In this embodiment, the fulcrums are all rods arranged under the ceiling, and in other feasible implementations, they can also be fixed objects such as walls and pillars. In addition, in this embodiment, each rear fulcrum 12 is provided with a hook 121 with an opening facing downward on the side facing each front fulcrum 11, and its function will be described in detail below.

[0068] The support member 2 can be composed of a flexible member such as a hanging rope, a steel cable, or a retractable telescopic rod. In other feasible implementations, it can also be composed of a combination of flexible members and rigid members. In this embodiment, the support member 2 is illustrated by a hanging rope. Each support member 2 is respectively connected between each front support point 11 and each rear support point 12 located on the same side of the vehicle body C. As shown in Figure 1, the two support members 2 are located on the opposite left and right sides of the vehicle body C, and each support member 2 has a first end 21 and a second end 22 at its two ends, respectively. Each first end 21 is connected and supported on the two front support points 11 through a detachable member 5. The specific connection method will be described in detail below. Each second end 22 is respectively formed with a ring portion 221, and each support member 2 is mounted with its ring portion 221 on the hook member 121 of each rear support point 12, thereby connecting and being supported on the two rear support points 12.

[0069] The fire blanket 3 is made of a special glass fiber material, which can isolate high temperature, air and toxic substances. When the vehicle body C catches fire, the fire blanket 3 completely covers the vehicle body C to ensure that the spontaneous combustion process of the vehicle body C will not spread to the surroundings, so that the burning of the vehicle body C can be slowed down until professional firefighters arrive at the scene for rescue or the toxic substances in the battery are burned out.

[0070] The fire blanket 3 is hung on two support members 2 at the same time, so as to be suspended in the air and located above the vehicle body C, and is usually folded at a position close to the first end 21. In this embodiment, since the position where the first end 21 of each support member 2 is connected to each front support point 11 is lower than the position where the second end 22 of each support member 2 is connected to each rear support point 12, each support member 2 is inclined toward each front support point 11, and the fire blanket 3 is hung on the lower end of the two support members 2, i.e., the first end 21, when folded, so that the fire blanket 3 will not slide by itself when folded and obstruct the line of sight of the parking space.

[0071] In more detail, the fire blanket 3 has a front side 31 formed toward the two front supporting points 11, and a rear side 32 formed toward the two rear supporting points 12. When the rear side 32 of the fire blanket 3 is pulled toward the two rear supporting points 12, the rear side 32 slides along the support members 2 toward the rear supporting points 12 and relatively away from the front side 31, thereby unfolding the fire blanket 3. Furthermore, in the present embodiment, the rear side 32 of the fire blanket 3 also has a buckle 33 on the opposite left and right sides, respectively, and each buckle 33 can be slidably mounted on each support member 2, respectively. When each buckle 33 is pulled, the fire blanket 3 can slide along the buckle 33 and unfold or fold along the support member 2.

[0072] In addition, the width of the fire blanket 3 is greater than the width of the horizontal shielding surface P, so that the opposite sides of the fire blanket 3 hang down outward on the outside of each support member 2 to form a hanging portion 34 respectively. It is worth mentioning that each front support point 11 and each rear support point 12 are also connected to a fence 13 under each support member 2. When the fire blanket 3 is hung on two support members 2, the two hanging portions 34 hang down from the outside of the two support members 2 and then are collected in the range surrounded by the two fences 13, thereby preventing the fire blanket 3 from falling onto the roof of the neighboring vehicle or other obstacles when falling, and failing to completely cover the vehicle body C originally set to be protected.

[0073] At least one pulling member 4 is connected to the rear side 32 of the fire blanket 3. The pulling member 4 can be pulled to make the rear side 32 of the fire blanket 3 unfold along the two support members 2 toward the two rear fulcrums 12. In this embodiment, there are two pulling members 4, which are respectively connected to the buckles 33 on both sides of the fire blanket 3. In other feasible embodiments, there can be only one pulling member 4, and the pulling member 4 is directly connected to the rear side of the fire blanket 3. Similarly, the fire blanket 3 can be unfolded along the support members 2 by pulling the pulling member 4.

[0074] Two detachable parts 5 are respectively arranged at the first end 21 of each support member 2, and each support member 2 is connected to each front support point 11 through each detachable part 5. In this embodiment, the detachable part 5 is composed of a quick-release pin. When the support member 2 is pulled by a pulling force toward the second end 22, the detachable part 5 located at the first end 21 can be pulled open. In other feasible embodiments, the detachable part 5 can also be a magnetic buckle to connect the support member 2 and the front support point 11 with magnetic force. In addition, the ring part 221 of the original support member 2 is sleeved on the groove member 121, so that the support member 2 has sufficient tension, so that the fire blanket 3 is supported by each support member 2 and suspended in the air.

[0075] Each detachable part 5 can be separated by being pulled. When the detachable parts 5 are separated, the first end 21 of each support member 2 is separated from each front fulcrum 11, and since the support member 2 loses tension, the ring portion 221 of the second end 22 slides down from the downward opening of the hook member 121 due to its own weight, thereby allowing the second end 22 to separate from the seat body 1 together with the first end 21. In other feasible implementations, each support member 2 is made of soft material and can be deformed at will, and the second end 22 of the support member 2 is fastened to the rear fulcrum 12. When the first end 21 of the support member 2 is separated from the front fulcrum 11, the second end 22 of the support member 2 will sag due to gravity even if it is still connected to the rear fulcrum 12, allowing the rear side 32 of the fire blanket 3 to slide down, thereby achieving the same purpose.

[0076] At least one positioning control component 6 is used to control each support member 2 to release its own supporting force at an appropriate time. In this embodiment, when the pulling member 4 pulls the rear side 32 of the fire blanket 3 toward the two rear supporting points 12, and the fire blanket 3 moves and unfolds to an area that can completely cover the vehicle body C, the positioning control component 6 first separates the two detachable parts 5, and then allows each support member 2 to release its own supporting force due to the separation of its first end 21 from each front supporting point 11, causing the fire blanket 3 to fall down due to loss of support.

[0077] In more detail, the positioning control component 6 includes two positioning nodes 61, each positioning node 61 is arranged on each support member 2 and is located relatively close to the second end 22. When the buckle 33 of the fire blanket 3 slides along each support member 2 and the fire blanket 3 slides and unfolds to cover the vehicle body C along with the buckle 33, each buckle 33 just abuts against the two positioning nodes 61. The two positioning nodes 61 are spherical and the outer diameter is larger than the inner diameter of the two buckle rings 33, so that the two buckle rings 33 cannot pass through the position where each positioning node 61 is set.

[0078] When the pulling member 4 pulls the rear side 32 of the fire blanket 3 toward the two rear supporting points 12, and the two buckles 33 have abutted against the two positioning nodes 61, since each buckle 33 is abutted by each positioning node 61, the pulling force applied to the fire blanket 3 by the pulling member 4 is transmitted to each supporting member 2. When the pulling force continues to act until the detachable parts 5 are pulled apart, the first end 21 of each supporting member 2 will be separated from the front supporting points 11, and then the fire blanket 3 will fall down due to the loss of support.

[0079] In addition to the above-mentioned method of transmitting through the structure, the positioning control device 6 can also be composed of a limit switch of the motor. The limit switch is also called a travel switch. It can achieve the same function as an electric rolling door, which can automatically stop or rebound after traveling a preset distance. The positioning control device 6 of the present invention can also be used.

[0080] In addition to the above-mentioned components, the fire blanket lowering mechanism of the present invention is optionally further provided with a detection device 7. The detection device 7 may be a smoke sensor or a temperature sensor. When the detection device 7 detects a fire, such as thick smoke or high temperature, it may send out a warning signal to trigger a fire prevention mechanism, so that the pulling member 4 is pulled by manpower or an automated mechanism to unfold the fire blanket 3. The specific implementation method of the fire prevention mechanism may be to pull the pulling member 4 through an automated mechanism, or to call maintenance personnel on site through a warning light or a warning bell, so that the maintenance personnel may come and pull the pulling member 4 by manpower, and both of these may achieve the purpose of setting up the detection device 7.

[0081] The above is a detailed description of the components of the fire blanket falling mechanism of the present invention. The actual process of the fire blanket 3 from deployment to falling when the vehicle body C is burning will be explained below. Since the structure of the present invention is symmetrically arranged, for the convenience of explanation, one side of the vehicle body C will be used for explanation below:

[0082] First, if Figure 1 As shown, the fire blanket 3 is hung on each support member 2 at the same time, and the fire blanket 3 is folded at the first end 21 of the support member 2 which is close to the front side of the vehicle body C and is lower, so that the fire blanket 3 does not slide automatically at ordinary times. When the vehicle body C catches fire for some reason, as shown in Figure 2, the detection device 7 detects signs of burning, issues a warning to notify on-site personnel or the automatic mechanism to start and pull the pulling member 4, so that the rear side 32 of the fire blanket 3 is unfolded toward the rear fulcrum 12. When the buckle 33 slides to the position of the positioning node 61, at this time, the unfolding area of ​​the fire blanket 3 has exceeded the area of ​​the horizontal shielding surface P. Because the area of ​​the horizontal shielding surface P is larger than the horizontal cross-sectional area of ​​the vehicle body C, the fire blanket 3 completely covers the top surface of the vehicle body C from above.

[0083] Next, since the inner diameter of the buckle ring 33 is smaller than the outer diameter of the positioning node 61, it cannot pass through the position of the positioning node 61, so that a locking relationship is generated between the buckle ring 33 and the positioning node 61. When the pulling member 4 is pulled continuously, the locking relationship between the buckle ring 33 and the positioning node 61 is transmitted to the support member 2, so that the support member 2 is indirectly pulled to separate the separable member 5. As shown in FIG. 3, when the separable member 5 is separated, the support member 2 loses its original tight tension, causing the support member 2 to be The ring portion 221 of the second end 22 of the component 2 falls off from the hook 121 of the rear fulcrum 12. As a result, as the two supporting components 2 are separated from the base body 1, the fire blanket 3 will also fall downward due to the loss of support and cover the vehicle body C located below. In addition to covering the vehicle body C from the roof down, the hanging portions 34 formed on both sides of the fire blanket 3 can also completely cover the sides of the vehicle body C, thereby greatly reducing the gap between the inside and outside of the fire blanket 3.

[0084] In more detail, when the fire blanket 3 falls with the supporting members 2, at this time, the pulling member 4 is still connected to the buckle 33, and the person responsible for pulling the pulling member 4 can directly let go, so that the pulling member 4 is pulled back in the opposite direction as the fire blanket 3 falls, so that the fire blanket 3 can completely cover the vehicle body C. Optionally, a secondary fastener 41 can be attached to the pulling member 4. In this embodiment, the secondary fastener 41 is also a quick-release pin that can be separated by pulling. When the fire blanket 3 falls, the pulling member 4 is pulled from the other end by the weight of the fire blanket 3, so that the pulling member 4 is separated from the position of the secondary fastener 41, so that the fire blanket 3 is separated from the pulling member 4, which can also achieve the effect of the fire blanket 3 completely covering the vehicle body C.

[0085] Through the fire blanket dropping mechanism of the present invention, the fire blanket 3 can slide along the extension direction of each support member 2 until the area is sufficient to cover the vehicle body C, so as to solve the problem that the space is too small to pull the fire blanket 3. In addition, the pulling member 4 is connected to the fire blanket 3 with one end, and the other end can be pulled by the operator and can be extended to any length as needed, thereby ensuring that the person pulling the pulling member 4 maintains a sufficient safety distance from the burning vehicle body C to avoid being burned by flames or choking the trachea by inhaling thick smoke.

[0086] In addition, through the horizontal shielding surface P of the base body 1, it is easier to visually judge whether the unfolded area of ​​the fire blanket 3 is sufficient, so as to avoid triggering the control positioning device 6 when the unfolded area of ​​the fire blanket 3 is insufficient, resulting in the fire blanket 3 falling and covering the vehicle body C with a gap between the fire blanket 3 and the ground, allowing high-temperature air or toxic substances to escape through the gap.

[0087] The above is a first embodiment of the fire blanket dropping mechanism of the present invention, in which a fixed dropping mechanism mounted on the ceiling is used to cover the fire blanket 3 on the vehicle body C. However, the fixed dropping mechanism is more suitable for a single parking space or an indoor space. If it is used in a large parking lot or an outdoor parking lot with a large number of parking spaces, the cost may be greatly increased and the practicality may be discounted. Therefore, the fire blanket dropping mechanism of the present invention also provides a mobile dropping mechanism, which can be used in parking lots with a large number of parking spaces or outdoor places without a ceiling, so that the present invention can adapt to more different types of places.

[0088] Please refer to Figures 4 to 7 , shown is a second embodiment of the fire blanket dropping mechanism of the present invention, which is a mobile dropping mechanism, which is usually stored in the tool room of the parking lot and is taken out when needed. For the convenience of understanding and comparison, the components of the second embodiment that are the same as or have similar functions to the first embodiment will be numbered with the same numbers. The second embodiment of the fire blanket dropping mechanism of the present invention includes a base 1, two support members 2, a fire blanket 3 and at least one pulling member 4, wherein:

[0089] The structure of the seat body 1 is roughly the same as that of the first embodiment, and the main difference is that the seat body 1 is movably arranged on the ground, and a roller group 14 is arranged on the bottom surface of the seat body 1 so that the seat body 1 can slide quickly and labor-savingly on the ground. The seat body 1 includes a U-shaped frame 15 and a movable frame 16. The U-shaped frame 15 has a notch 151, and the movable frame 16 is slidably arranged on two slide rails 152 on the inner edges of the opposite side edges of the U-shaped frame 15, so that the movable frame 16 can move forward and backward relative to the U-shaped frame 15 through the notch 151, wherein the two front fulcrums 11 are arranged on the top surface of the U-shaped frame 15, and the two rear fulcrums 12 are arranged on the top surface of the movable frame 16. When the movable frame 16 is displaced relative to the U-shaped frame 15, the two rear fulcrums 12 are also relatively close to or away from the two front fulcrums 11.

[0090] The support member 2 is changed into a telescopic rod with an extendable length in the second embodiment, which can also achieve the purpose of supporting the fire blanket 3. It should be noted that since the distance between each front support point 11 and each rear support point 12 is not fixed, the fence 13 is not set in this embodiment. Of course, in other feasible implementation forms, a fence 13 with the same telescopic structure as the support member 2 can also be set.

[0091] In this embodiment, a pulley 122 is respectively installed on the two rear fulcrums 12, and each pulling member 4 passes through the pulley 122 one by one, so that in this embodiment, the pulling member 4 can be pulled in a direction different from the original pulling direction of the first embodiment, so that when the operator pulls the pulling member 4, he is not restricted by space and terrain, and can also pull the fire blanket 3 to unfold.

[0092] The above are the main structural differences between the second embodiment of the present invention and the first embodiment. The actual use of the second embodiment will be described below:

[0093] As shown in FIG. 5 , the drop mechanism can be stored in the tool room of the parking lot at ordinary times, and the movable frame 16 is stored in the U-shaped frame 15, so as to reduce the overall volume of the seat body 1. When a vehicle is on fire, the drop mechanism is pushed out of the tool room and the roller group 14 is used to quickly push the drop mechanism to the car body C on fire. First, the notch 151 of the U-shaped frame 15 is aligned with the car body C and pushed, so that the car body C enters the U-shaped frame 15 through the notch 151, and then the movable frame 16 is pulled out of the U-shaped frame 15 from the notch 151 in the direction close to the rear side of the car body C. As shown in FIG. 6 , the movable frame 16 moves along the notch 151. The two slide rails 152 slide out of the U-shaped frame 15 horizontally and expand the seat body 1 to the maximum. At this time, the pulling member 4 can be pulled (the direction can be adjusted according to the current situation) to expand the fire blanket 3 along the extension direction of the support member 2, which can also achieve the purpose of making the fire blanket 3 completely cover the vehicle body C and fall down to complete the coverage. When the fire subsides and is extinguished, the movable frame 16 is pushed back to the notch 151 of the U-shaped frame 15 to complete the folding of the seat body 1. Finally, the seat body 1 is pushed back to the tool room for storage in case of emergency next time, so that the present invention can also have the effects of easy storage and increased versatility.

[0094] The above is a detailed description of the second embodiment of the present invention. The third embodiment of the present invention will be described below. The structure of the third embodiment of the present invention is substantially the same as that of the first embodiment, and the main differences are:

[0095] like Figure 8 As shown, the number of the pulling member 4 is changed to one, and the end is connected to the middle section of a cross bar 42, and the two ends of the cross bar 42 are respectively connected to the two buckle rings 33 of the fire blanket 3. When the pulling member 4 is pulled, the pulling force is transmitted to the buckle rings 33 at both ends through the cross bar 42, so that the deployment speed of both sides of the fire blanket 3 can be kept consistent, so that the two sides of the fire blanket 3 can be deployed more synchronously. When the buckle ring 33 of the fire blanket 3 is stuck on the positioning node 61, the pulling force is also transmitted from the pulling member 4 to the buckle ring 33, and then transmitted to the support member 2 via the positioning node 61. The subsequent processes are the same as those in the first embodiment, so that the present invention can still achieve the same effect of causing the fire blanket 3 to fall under different pulling member 4 states and quantities.

[0096] However, the above embodiments are only used to illustrate the present invention, not to limit the present invention. Any replacement of equivalent components should still fall within the scope of the present invention. In addition, the front side of the vehicle body C in the figure is only for illustrative purposes and is not intended to be limiting. In other feasible implementations, even if the front and rear sides of the vehicle body C are replaced, they should still fall within the scope of the present invention.

[0097] In summary, it can be understood by those skilled in the art that the present invention can indeed achieve the aforementioned objectives, and has complied with the provisions of the Patent Law and has been applied for in accordance with the law.

2. The fire blanket dropping mechanism according to claim 1, characterized in that: Two detachable parts are further provided, each of which is respectively arranged at the first end of each support member, and each support member is connected to each front supporting point through each detachable part. The fire blanket is supported by each support member and suspended in the air. Each detachable part can be separated due to being pulled. When each detachable part is separated, the first end of each support member is separated from each front supporting point, so that each support member releases its own supporting force due to the falling of the first end, and then the fire blanket falls down due to its own weight due to the loss of support.

3. The fire blanket dropping mechanism according to claim 2, characterized in that: Each of the detachable parts is respectively composed of a fastener, each of the fasteners is composed of a quick-release buckle structure and is arranged between the first end of each support part and each of the front fulcrums, each of the support parts is formed with a ring portion at the second end, and each of the rear fulcrums is provided with a hook with an opening facing downward on the side facing each of the support parts, and each of the support parts is respectively connected to the hook of each of the rear fulcrums by the ring portion. When the fastener of each of the detachable parts is pulled and separated, the first end of each of the support parts falls down due to separation from the front fulcrum, and the second end of each of the support parts loses tension, causing each of the ring portions to slide from the opening of each of the hooks due to its own weight.

4. The fire blanket dropping mechanism according to claim 2, characterized in that: Each of the support members is made of soft material and can be deformed at will, and the second end of the support member is fixed on the rear support point. When the first end of the support member is separated from the front support point, the second end of the support member sags due to gravity, causing the fire blanket to slide down.

5. The fire blanket dropping mechanism according to claim 2, characterized in that: The fire blanket is provided with a buckle on two opposite sides of the rear side, and each buckle can be slidably mounted on each support member. When each buckle is pulled, the fire blanket can be unfolded or folded as the buckle slides. The positioning control component includes two positioning nodes, each of which is provided on each support member and is relatively close to the second end. When each buckle slides along each support member and the fire blanket is unfolded to cover the vehicle body, each buckle abuts against the two positioning nodes. The two positioning nodes are spherical and have an outer diameter greater than the inner diameter of the two buckle rings, so that the two buckle rings cannot pass through the positions where the positioning nodes are set. When the pulling member pulls the rear side of the fire blanket toward the two rear fulcrums and the two buckle rings abut against the two positioning nodes, since each buckle ring is abutted by the positioning nodes, the pulling force applied to the fire blanket by the pulling member is transmitted to each supporting member. When the pulling force continues to act until the separable members are pulled apart, each supporting member falls down together with the fire blanket.

6. The fire blanket dropping mechanism according to claim 1, characterized in that: The heights of the two front supporting points are lower than the two rear supporting points, so that the two supporting members are inclined in the same direction. When the fire blanket is folded, it is hung on the first ends of the two supporting members, so that the fire blanket will not slide automatically and obstruct the sight of the parking space.

7. The fire blanket dropping mechanism according to claim 1, characterized in that: A detection device is further provided. When the detection device detects a fire, a warning signal can be issued to cause the pulling member to pull and unfold the fire blanket by manpower or an automatic mechanism.
