Description

Technical Field

[0001] The utility model relates to the technical field of fire-fighting equipment for chassis of new energy vehicles, and in particular to a fire-fighting sprinkler cart for the chassis of new energy vehicles. Background Art

[0002] New energy vehicles refer to vehicles that use unconventional automotive fuels as their power source, or use new automotive power units, and have new technologies and new structures. Compared with traditional gasoline or diesel vehicles, these vehicles can effectively reduce environmental pollution and save energy. New energy vehicles mainly include the following types:

[0003] Electric Vehicle (EV): A fully electric vehicle is powered by an electric motor, which is powered by an onboard battery. This type of vehicle requires plugging in to recharge.

[0004] Plug-in hybrid electric vehicle (PHEV): This type of vehicle has both an electric motor and an internal combustion engine. They can be plugged in to charge, run on electricity, and switch to the internal combustion engine when the electricity runs out.

[0005] Hybrid Electric Vehicle (HEV): A hybrid electric vehicle is also equipped with an electric motor and an internal combustion engine, but is primarily driven by the internal combustion engine, with the electric motor providing additional power. These vehicles are usually not plugged in, and the battery is charged by recovering braking energy and the internal combustion engine.

[0006] Hydrogen Fuel Cell Electric Vehicle (FCEV): These vehicles use hydrogen fuel cells to generate electricity to drive an electric motor. Their main emission is water vapor, making them a very clean transportation option.

[0007] In addition to these mainstream types, there are some other new energy technologies being explored, such as solar cars, air-energy cars, etc.

[0008] New energy vehicles are of great significance in reducing greenhouse gas emissions, lowering energy consumption, and reducing the impact on the environment. Governments of various countries have also introduced various policies to encourage the development and popularization of new energy vehicles. With the advancement of technology and the reduction of costs, new energy vehicles will gradually become mainstream.

[0009] However, since new energy vehicles need to use batteries as power sources, and the batteries are mostly located above the vehicle chassis, new energy vehicles now often experience chassis fires. When the chassis burns, it is difficult to effectively extinguish the fire using conventional fire-fighting methods because the fire source is located at a low location.

[0010] The utility model patent with patent application number 2023217525783 discloses a fire extinguishing device for new energy vehicles. The movable chassis is moved to the lower part of the fire position of the chassis of the new energy vehicle. The spray end of the sprinkler head is facing the chassis of the new energy vehicle. The fire pump is turned on, and the fire extinguishing medium is sprayed to the fire position of the chassis of the new energy vehicle through the sprinkler head. In this way, the fire position can be extinguished in a small space, which simplifies the operation, improves the fire extinguishing efficiency, and avoids the safety hazards caused by the inability to completely extinguish the fire by traditional fire extinguishing methods.

[0011] However, the above technical solution has a complex structure and cumbersome operation, and is not conducive to rapid fire fighting of the chassis of new energy vehicles. Utility Model Content

[0015] Carriage panels and armrests;

[0016] The vehicle plate is arranged horizontally, and is formed by bending and welding of stainless steel. A hollow cavity is arranged inside the vehicle plate, and a spray hole connected to the cavity is opened on the vehicle plate. A joint for quick installation and connection with a fire hose is arranged on the vehicle plate, and casters are installed on the lower end surface of the vehicle plate;

[0017] The armrest is mounted on the vehicle board, the armrest is arranged to be rotatably swung and adjusted, and a limiting mechanism is arranged at the mounting connection position between the armrest and the vehicle board, and the limiting mechanism performs limiting control on the armrest after the swing adjustment.

[0018] As an improvement, when the vehicle plate extends into the floor of the new energy vehicle to perform fire spraying, the armrest rotates and swings in a direction away from the vehicle plate to a horizontal setting;

[0019] When the vehicle board is stored, the armrest is rotated and swung toward the vehicle board to be horizontal, and is arranged to overlap with the vehicle board.

[0020] As an improvement, the thickness of the vehicle plate is 40-50 mm, and the ground clearance h of the vehicle plate is less than the ground clearance H of the chassis of the new energy vehicle.

[0021] As an improvement, the vehicle plate is arranged in a step-shaped manner, and the spray holes are evenly distributed on the top end surface and the inclined side wall surface of the vehicle plate.

[0022] As an improvement, a support column is provided in the cavity to strengthen the cavity.

[0023] As an improvement, the casters include fixed casters and universal casters;

[0024] The directional caster is arranged at the end of the vehicle board away from the handrail;

[0025] The universal caster is arranged at the end of the vehicle board close to the handrail.

[0026] As an improvement, the armrest is connected to the vehicle plate via a mounting seat, the mounting seat forms a swing mounting groove around the end of the armrest, and the armrest is swingably inserted into the swing mounting groove;

[0027] A pin shaft is passed through the mounting seat, and the armrest rotates and swings around the pin shaft.

[0028] As an improvement, a reinforcing plate is provided inside the end portion where the handrail is mounted and connected to the mounting seat.

[0029] As an improvement, the joint is installed below the armrest, and the joint includes a connector and an adapter, the connector is fixedly connected to the vehicle plate, and the connector is connected to the cavity;

[0030] The adapter and the connector are interlaced and spliced, and the adapter and the fire belt connector are detachably connected via a buckle.

[0031] As an improvement, the limiting mechanism includes a limiting rod and a reset member;

[0032] The two ends of the limit rod are passed through the mounting seats on both sides for transportation, and the ends of the limit rod are placed in the swing mounting groove. The mounting seat is provided with a limit groove for the limit rod to move.

[0033] The reset member is disposed between the mounting seat and the limiting rod, and the reset member pulls the limiting rod to reset along the limiting groove.

[0034] The beneficial effects of the utility model are:

[0035] (1) The utility model uses a flatbed trolley as a prototype, combines a fire extinguishing device with the flatbed trolley, and uses the flatbed trolley as a nozzle. When extinguishing a fire, the trolley's plate is extended under the chassis of the new energy vehicle.

[0053] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0054] Embodiment 1:

[0055] like Figures 1 to 4 As shown, a fire sprinkler cart for a new energy vehicle chassis includes:

[0056] Car plate 1 and handrail 2;

[0057] The vehicle plate 1 is arranged horizontally, a hollow cavity 11 is arranged inside the vehicle plate 1, and a spray hole 12 connected to the cavity 11 is opened on the vehicle plate 1, a joint 3 for quick installation and connection with a fire hose is arranged on the vehicle plate 1, and a caster 10 is installed on the lower end surface of the vehicle plate 1;

[0058] The armrest 2 is mounted on the vehicle plate 1 and is provided with a rotational swing adjustment arrangement. A limiting mechanism 4 is provided at the mounting connection position between the armrest 2 and the vehicle plate 1 , and the limiting mechanism 4 performs limit control on the armrest 2 after the swing adjustment.

[0059] Specifically, when the vehicle plate 1 is extended into the floor of the new energy vehicle for fire spraying, the armrest 2 is rotated and swung in a direction away from the vehicle plate 1 to a horizontal setting. After the joint 3 is connected to the fire hydrant or the fire extinguishing medium supply equipment, the operator holds the armrest 2 and can extend the vehicle plate 1 under the chassis of the new energy vehicle. After it is extended into place, the fire extinguishing medium is sprayed to extinguish the fire on the chassis;

[0060] When the vehicle plate 1 is stored, the armrest 2 is rotated and swung toward the vehicle plate 1 to be horizontal, and is arranged to overlap with the vehicle plate 1, which can reduce the occupied space and facilitate the storage of the fire sprinkler cart.

[0061] In addition, the thickness of the vehicle plate 1 is 40-50 mm, and the ground clearance h of the vehicle plate 1 is less than the ground clearance H of the chassis of the new energy vehicle.

[0062] Specifically, for example, the chassis height of Tesla Model Y is 138mm, while the chassis ground height of BYD Han EV is about 145mm. Therefore, differences in vehicle design and target usage scenarios will lead to differences in chassis height. Therefore, in order to make the fire sprinkler cart for the new energy vehicle chassis suitable for various types of new energy vehicles, it is necessary to ensure that the ground clearance h of the vehicle plate 1 can be lower than the floor height H of all types of new energy vehicles. To ensure this height factor, the thickness of the vehicle plate 1 must be reduced, while ensuring that the cavity 11 can meet the space required for spraying. Through repeated tests, it is determined that the thickness of the vehicle plate 1 is 40-50mm, and the vehicle plate 1 is formed by welding with 1.5-2mm stainless steel material, and its strength can adapt to the medium pressure in the cavity 11.

[0063] Embodiment 2:

[0064] With reference to Example 1, the difference between Example 2 of the utility model and Example 1 is described as follows:

[0065] like Figure 1 As shown, the vehicle plate 1 is arranged in a terraced shape, and the spray holes 12 are evenly distributed on the top end surface 13 and the inclined side wall surface 14 of the vehicle plate 1 .

[0066] Compared with the existing fire-fighting devices of the chassis of new energy vehicles, the vehicle plate 1 of the present application, as a sprinkler head, not only adopts a flat spraying method to extinguish fires, but also adopts a diffuse spraying method to extinguish fires.

[0067] Among them, the length of the vehicle plate 1 is 600-1200mm, preferably 754mm, and the width is 450-650mm, preferably 508mm. When in use, the length of the vehicle plate 1 covers the width direction of the new energy vehicle, and a number of spray holes 12 are evenly distributed on the top end face of the vehicle plate 1. The size of the spray holes 12 is 2-5mm, preferably 2.5-3mm, and there are 80-120, preferably 96, distributed on the top end face, divided into 12 groups, each group of 8 distributed in the width of the vehicle plate 1, and the spacing between the holes is 60mm.

[0068] In addition, 15-20 spray holes 12 are opened on the inclined side wall surface 14 on the front side of the vehicle plate 1, preferably 18-19, preferably 10 in the first row and 8-9 in the second row, and 20-26 spray holes 12 are opened on the inclined side wall surfaces 14 on both sides of the vehicle plate 1, preferably 24, 12 in the first row and 12 in the second row.

[0069] Specifically, the spray diffusion effect of the vehicle panel 1 is achieved by cooperating with the spray holes 12 through the inclined side wall surface 14 .

[0070] It is further explained that a support column 111 is provided in the cavity 11 for strengthening the cavity 11 , so as to ensure that the strength of the cavity 11 in the vehicle panel 1 can meet the hydraulic pressure during spraying.

[0071] Embodiment 3:

[0072] With reference to Example 1, the difference between Example 3 of the utility model and Example 1 is described as follows:

[0073] like Figure 2 As shown, the caster 10 includes a fixed caster 101 and a universal caster 102;

[0074] The fixed caster 101 is arranged at the end of the vehicle board 1 away from the handrail 2;

[0075] The universal caster 102 is disposed at the end of the vehicle board 1 close to the handrail 2 .

[0076] It should be noted that the height of the fixed caster 101 and the universal caster 102 is 50-80 mm. Based on the height of the caster 10 and the thickness of the vehicle board 1, the overall height from the vehicle board 1 to the ground is 90-130 mm, which is suitable for the chassis height of most new energy vehicles currently sold on the market.

[0077] Embodiment 4:

[0078] With reference to Example 1, the difference between Example 4 of the utility model and Example 1 is described as follows:

[0079] like Figures 5 to 7As shown, the armrest 2 is connected to the vehicle plate 1 through a mounting seat 21, and the mounting seat 21 forms a swing mounting groove 22 around the end of the armrest 2, and the armrest 2 is swingably inserted in the swing mounting groove 22;

[0080] A pin shaft 211 is provided on the mounting seat 21 , and the armrest 2 rotates and swings around the pin shaft 211 . After the armrest 2 rotates and swings to a certain position, it is locked and limited by the limiting mechanism 4 .

[0081] Specifically, the limiting mechanism 4 includes a limiting rod 41 and a reset member 42;

[0082] The two ends of the limiting rod 41 are passed through the mounting seats 21 on both sides for transportation, and the ends of the limiting rod 41 are placed in the swing mounting groove 22. The mounting seat 21 is provided with a limiting groove 212 for the limiting rod 41 to move.

[0083] The reset member 42 is disposed between the mounting seat 21 and the limiting rod 41 , and the reset member 42 pulls the limiting rod 41 to reset along the limiting groove 212 .

[0084] It should be noted that the armrest 2 is limited by the limit rod 41, so that the armrest 2 is fixed in each working position. When the state of the armrest 2 needs to be switched, the limit rod 41 is pulled down along the limit groove 212 so that the armrest 2 loses the limiting interference of the limit rod 41. Then, the armrest 2 is in a free state and can be rotated and swung at will. After the armrest 2 swings to the corresponding position, the limit rod 41 is reset through the reset member 42, and the limit rod 41 is used to interfere with the armrest 2, so that the armrest 2 is in a locked state.

[0085] It is further explained that when the mounting seat 21 is connected to the vehicle plate 1, the bottom surface of the mounting seat 21 is connected to the upper end surface of the bottom plate of the vehicle plate 1 by welding. With such an arrangement, on the one hand, the force for pushing the cart acts directly on the bottom plate, and the universal wheel below is also directly welded under the bottom plate, so that the force transmission is more direct and will not cause deformation of the water tank; on the other hand, the height of the entire mounting seat 21 is also reduced, so that the cart can be more smoothly sent under the chassis of the new energy vehicle.

[0086] In addition, a reinforcing plate 201 is provided in the end portion where the armrest 2 is installed and connected to the mounting seat 21. Since the armrest 2 needs to be repeatedly operated and used during the operation of the cart, and the armrest 2 is a hollow round tube, it repeatedly collides with the limit rod 41, which will cause concave deformation. The reinforcing plate 201 is exactly set at the position where the armrest 2 and the limit rod 41 collide and squeeze, thereby strengthening the strength of the armrest 2 and avoiding the occurrence of concave deformation.

[0087] Embodiment 5:

[0088] With reference to Example 1, the difference between Example 4 of the utility model and Example 1 is described as follows:

[0089] like Figures 8 to 10 As shown, the joint 3 is installed below the armrest 2, and the joint 3 includes a connector 31 and an adapter 32. The connector 31 is fixedly connected to the vehicle plate 1, and the connector 31 is connected to the cavity 11;

[0090] The adapter 32 and the connector 31 are interlaced and spliced, and the adapter 32 and the fire hose connector are detachably connected via a buckle.

[0091] It should be noted that the diameter of the existing fire hose connector is much larger than the thickness of the vehicle plate 1. Therefore, the connector 31 and the adapter 32 are needed as a transfer. Through the conversion of the adapter 32, the adapter 32 can be directly connected to the connector of the fire hose, so that the fire sprinkler cart for the chassis of new energy vehicles can directly use the fire hydrant as the source of the fire extinguishing agent.

[0092] The connector 31 adopts the existing quick-connect pipe connector. By plugging, the connector 31 and the adapter 32 can be quickly installed and connected, reducing assembly time.

[0093] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
