Description

TECHNICAL FIELD

[0001] The application relates to the technical field of motor vehicles, in particular to a new energy vehicle fireproof anti-collision buffer vehicle. BACKGROUND

[0002] The anti-collision buffer vehicle is the core equipment for road operation safety protection, and is mainly applied to expressway, urban road, bridge and tunnel construction, and is especially suitable for areas with large traffic flow and high speed, can build a buffer area at the accident site, protect rescue personnel and equipment, and reduce the impact acceleration suffered by the occupants of the collision vehicle. The anti-collision buffer vehicle can absorb the impact energy of a 2-ton vehicle at a speed of 100 km / h through the double deformation of the aluminum energy absorption module and the frame structure.

[0003] The anti-collision device and the anti-collision buffer vehicle are provided with a buffer module and a mounting plate, and the anti-collision module is arranged between the buffer module and the mounting plate. The anti-collision module includes a front anti-collision group arranged on the side of the mounting plate and a rear anti-collision group arranged on the side of the buffer module. When the buffer module is impacted, the buffer module drives the rear anti-collision group to move towards the mounting plate and the front anti-collision group. At this time, the rear anti-collision group drives the buffer module to move away from the mounting plate, and the front anti-collision group drives the mounting plate to move away from the buffer module. Through this design, the buffer module is prevented from colliding with the mounting plate, thereby protecting the oil cylinder driving device. The application can protect the oil cylinder driving device when the rear vehicle is impacted, avoid the oil cylinder driving device from being damaged and scrapped due to impact, and reduce the replacement cost.

[0004] However, with the continuous development of new energy technology, the proportion of new energy vehicles in the total number of vehicles is increasing. Compared with fuel vehicles, the new energy vehicles are more likely to catch fire after impact because the battery pack is arranged on the chassis. The fire spreads rapidly, and the current anti-collision buffer vehicle is not enough to deal with the risk after the new energy vehicle is impacted. SUMMARY

[0025] A trigger assembly is arranged to drive the two folding rods away from each other when the vehicle hits the rear support.

[0045] 3. By cooperating the force storage mechanism, the firing locking mechanism and the trigger assembly, the ejection rod can be ejected to the rear collision vehicle on the storage box when the rear vehicle hits the rear support at any position, thereby driving the middle area counterweight head and the fire blanket to be ejected to the rear, so that the fire blanket is deployed under the chassis of the rear collision vehicle;

[0046] 4. By hingedly mounting the storage box on the front support and arranging lateral moving parts on both sides of the hinge part of the storage box, when the rear vehicle is offset and hits one end of the rear support, the storage box can be automatically controlled to deflect to the end direction, and the fireproof blanket can be further delayed to be ejected, so that the fireproof blanket can be as accurately as possible ejected to the bottom of the chassis of the collision vehicle parked behind the crash buffer vehicle, thereby ensuring the rescue efficiency.

[0063] The technical solutions of the present application will be described clearly and completely below with reference to the drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application. Embodiment one

[0064] The present application discloses a new energy vehicle flame-retardant anti-collision buffer vehicle. Referring to Figure 1 , Figure 2 and Figure 3 , which comprises a carrying truck 1 and a buffer module, the buffer module comprises:

[0065] A front support 21 is hingedly installed at the tail of the carrying truck 1, and the tail of the carrying truck 1 is hingedly provided with a hydraulic cylinder, a gas cylinder or an electric push rod for driving the front support 21 to overturn in the horizontal direction and the vertical direction. The overturning structure of the front support 21 is a conventional technical means, which will not be described here.

[0066] A rear support 22 is connected to the front support 21, and the two are spaced apart.

[0067] A metal bent pipe 23 and a buffer pad 24 are arranged between the front support 21 and the rear support 22, wherein the metal bent pipe 23 is provided with two and the arc tops of the two are oppositely arranged, and the buffer pad 24 can be a honeycomb aluminum alloy plate or other forms of metal energy-absorbing plate.

[0068] A fire blanket 31 is accommodated at the lower end surface of the front support 21, which is specifically woven by fire-retardant fiber, and is folded in a wave shape in the horizontal direction, so that the free end of the fire blanket 31 can be stretched and quickly unfolded and flattened after stretching.

[0069] Fire-retardant bags 32 filled with fire-retardant agent, upper end face provided with injection port 321, injection port 321 provided with temperature control switch 322, temperature control switch 322 used to sense ambient temperature and open injection port 321 when reaching the set temperature, fire blanket 31 provided with a plurality of fire-retardant bags 32 arranged in an array. In a specific arrangement, fire-retardant bags 32 can be pasted on the upper surface of fire blanket 31, or wrapped in fire blanket 31 with only injection port 321 and temperature control switch 322 exposed, in an optimal embodiment, fire blanket 31 is provided with a double-layer structure and the fire-retardant bags 32 are wrapped and protected inside. Moreover, the fire-retardant agent is pressurized and filled in the fire-retardant bags 32, the injection port 321 is provided with an atomizing nozzle, in another embodiment, a hose can also be connected to the fire-retardant bags 32, and the hose is connected to a high-pressure fire-retardant tank (not shown in the figure) installed on the carrying truck 1, the hose is also embedded in the double-layer structure of the fire blanket, and the high-pressure fire-retardant tank can continuously deliver high-pressure fire-retardant agent to the fire-retardant bags 32 after the stored fire-retardant agent in the fire-retardant bags 32 is injected. In addition, the temperature control switch 322 can be a micro control element composed of a temperature sensor and a micro electromagnetic valve, or a hot melt plastic, a sealing wax or a liquid-filled heat-sensitive glass ball / tube sealed at the injection port 321, considering the actual use cost and convenience, in this embodiment, the temperature control switch 322 is selected to be a sealing plug made of hot melt plastic.

[0070] Ejection device for driving the fire blanket 31 to unfold and lay flat under the rear vehicle chassis when the vehicle hits the rear support 22.

[0071] And referring to Figure 3 , the free end of the fire blanket 31 is fixedly connected with a middle weight head 311 and at least two side weight heads 312 arranged on both sides of the middle weight head 311, the side weight heads 312 are flexibly connected with the middle weight head 311, specifically, an elastic rod 313 is connected between the middle weight head 311 and the side weight head 312, the elastic rod 313 can be a hollow high-toughness plastic rod. The ejection device is used to eject the middle weight head 311 to an area more than 2.5m behind the rear support 22 and within 12cm from the ground, the area more than 2.5m is set to ensure that the fire blanket 31 can span the area from the front of the collision vehicle to the battery pack, and the area within 12cm from the ground is set to ensure that the ejected middle weight head 311 can enter under the chassis of the collision vehicle, so as to ensure that the fire blanket 31 can be ejected to the chassis battery pack of most new energy vehicles.

[0072] Therefore, the anti-collision buffer vehicle of the present application is parked in the construction area, and the buffer module is turned to horizontal, when a vehicle hits the rear support 22, the metal elbow pipe 23 between the rear support 22 and the front support 21 deforms first to absorb the initial impact energy, then the buffer pad 24 collapses to further absorb the impact energy, which can effectively reduce the vehicle collision energy and protect the construction personnel and the rear vehicle occupants, avoiding secondary injury.

[0073] In this process, the ejection device ejects the middle zone counterweight head 311 to the rear of the collision vehicle under the chassis, the middle zone counterweight head 311 carries two edge zone counterweight heads 312 to deploy the fire blanket 31 under the chassis of the rear collision vehicle, and once the rear collision vehicle is a new energy vehicle and the battery pack catches fire, the flame sprayed from the battery pack heats the temperature control switch 322 on the fire barrier bag 32, such as melting the hot melt plastic plug, at this time the high-pressure fire retardant in the fire barrier bag 32 is sprayed out of the spray port 321, and the fire retardant can be automatically sprayed to the bottom of the new energy vehicle to inhibit the self-ignition process of the new energy vehicle in the first time, avoiding the rapid spread of the fire and causing the collision vehicle to be damaged.

[0074] Moreover, once the fire retardant stored in the multiple fire barrier bags 32 in the fire blanket 31 is sprayed out, the vehicle still has a fire, and the high-pressure fire retardant tank valve on the carrying truck 1 can be further opened to continuously deliver high-pressure fire retardant to the fire barrier bag 32 through the hose, and then sprayed out of the multiple spray ports 321 of the multiple fire barrier bags 32, which can form continuous and multi-point fire retardant spraying, thereby timely dealing with the self-ignition risk and reliably solving the common phenomenon that the new energy vehicle is burned after self-ignition and rescue personnel cannot arrive at the vehicle. Moreover, in the process of dealing with the self-ignition risk, the fire blanket 31 is ejected to the bottom of the collision vehicle chassis, mainly aiming at the ignition point such as the battery pack, and the fire retardant is sprayed from bottom to top, which has better fire suppression effect and does not require personnel to approach the collision vehicle, thereby greatly reducing the probability of injury to rescue personnel when dealing with the fire.

[0075] Specifically, referring to Figure 2 , Figure 4 and Figure 5 , the ejection device comprises:

[0076] The storage box 4 is installed below the front support 21 and has an open end near the rear support 22, and the fire blanket 31 is folded in a wave shape in the storage box 4.

[0077] The ejection rod 5 is slidingly arranged on the storage box 4, and the middle zone counterweight head 311 is movably connected to the free end of the ejection rod 5. Specifically, the ejection rod 5 is arranged in the opening direction of the storage box 4, and the middle zone counterweight head 311 is gap-set on the free end of the ejection rod 5 or magnetically attracted to the free end of the ejection rod 5.

[0078] The energy storage mechanism is used to store initial kinetic energy for the ejection rod 5. And

[0079] The firing locking mechanism is used to lock the ejection rod 5 storing the initial kinetic energy, and to release the locking of the ejection rod 5 when the vehicle collides with the rear support 22, referring to Figure 5 , Figure 6 andFigure 7 , specifically comprising:

[0080] The two folding rods 61 are oppositely arranged and the bending portions thereof are hinged to the storage box 4. The inner angles of the two folding rods 61 are oppositely arranged. In the specific arrangement, the end of the folding rod 61 away from the rear support 22 is a long rod segment and the end close to the rear support 22 is a short rod segment.

[0081] The locking hook 62 is fixed to the end of the folding rod 61 close to the rear support 22 and the hook portion thereof faces outward.

[0082] The locking cylinder 51 is fixed to the end of the ejection rod 5 close to the locking hook 62 and the inner wall thereof is fixed with a shackle 52 suitable for hooking with the two locking hooks 62. When the ends of the two folding rods 61 away from the locking cylinder 51 are far away from each other, the locking hook 62 is disengaged from the shackle 52.

[0083] The reset elastic member 63 is arranged between the two folding rods 61 and is used to drive the end of the folding rod 61 provided with the locking hook 62 to abut against the inner wall of the locking cylinder 51. Specifically, the reset elastic member 63 is arranged as a tension spring and the two ends thereof are fixed to the inner walls of the long rod segments of the folding rods 61. When the locking hook 62 on the folding rod 61 is hooked and connected with the shackle 52, the reset elastic member 63 is in the stretched state to ensure that the locking hook 62 and the shackle 52 cannot be disengaged automatically when the carrying truck 1 runs on a bumpy road section, thereby avoiding the fire blanket 31 from being ejected accidentally.

[0084] The trigger assembly is used to drive the ends of the two folding rods 61 away from the locking cylinder 51 to be far away from each other when the vehicle hits the rear support 22.

[0085] Therefore, when the vehicle hits the rear support 22, the trigger assembly drives the long rod segments of the two folding rods 61 to be far away from each other, so that the folding rods 61 are flipped on the storage box 4 with the bending portions thereof, the short rod segments of the two folding rods 61 are close to each other, thereby making the two locking hooks 62 disengage from the shackle 52 on the locking cylinder 51. Immediately, the energy stored in the force storage mechanism is converted into the kinetic energy of the ejection rod 5, so that the ejection rod 5 is ejected rearward on the storage box 4 to hit the vehicle, thereby driving the middle zone counterweight head 311 and the fire blanket 31 to be ejected rearward to make the fire blanket 31 unfolded below the chassis of the rearward hitting vehicle.

[0086] Further, referring to Figure 4 , Figure 5 and Figure 7 , the above-mentioned trigger assembly comprises:

[0087] The first cylinder 71 is located between the ends of the two folding rods 61 away from the locking cylinder 51 and the axial two ends thereof are provided with the first piston rod 72. The first piston rod 72 points to the inner wall of the long rod segment of the adjacent folding rod 61. The first cylinder 71 is fixed to the lower end face of the storage box 4. Correspondingly, the folding rods 61 and the ejection rod 5 are also arranged on the lower end face of the storage box 4.

[0088] The trigger 73 is provided with multiple and at least distributed in the middle and both ends of the length of the rear bracket 22, for when the vehicle hits the trigger 73 to the first cylinder 71 to deliver fluid medium to make the two first piston rod 72 away. In a specific setting, the trigger 73 can also be the second cylinder plus the second piston rod, just need to be fixed on the front bracket 21, and the second piston rod against the front bracket 21, the second cylinder is full of fluid medium, the second cylinder and the first cylinder 71 between the two first piston rod 72 cavity through the pipeline connection, and to ensure the sensitivity of the trigger 73, the second cylinder cross section is greater than the first cylinder 71 cross section.

[0089] Thus, when the rear bracket 22 is hit by the vehicle in any rear direction, the rear bracket 22 and the front bracket 21 between the spacing or local spacing decreases, the rear bracket 22 can push the second piston rod in the second cylinder to slide, to deliver the fluid medium in the second cylinder to the cavity between the two first piston rod 72 in the first cylinder 71 through the pipeline, and then make the two first piston rod 72 from the first cylinder 71 end out, can push the long rod segment of the two folding rod 61 away, so that the two lock hook 62 and the shackle 52 on the lock cylinder 51 unhook, the ejection rod 5 drive the fire blanket 31 pop out. And because the second cylinder cross section is greater than the first cylinder 71 cross section, so even if the displacement of the rear bracket 22 is shorter after being hit back, the two first piston rod 72 can be triggered effectively, and then trigger the fire blanket 31 to pop out, the reaction is more sensitive.

[0090] Even if the fire blanket 31 is ejected after a slight collision, it only needs to move back the second piston rod, push the ejection rod 5 and fold the fire blanket 31 into the storage box 4, so that the lock cylinder 51 approaches the two lock hooks 62, and then the two folding rods 61 are pulled, so that the two lock hooks 62 extend into the lock cylinder 51 and are hooked with the shackle 52. In the case of no great damage to the overall structure, it can be recovered and reused after reinstallation.

[0091] In another possible embodiment, the trigger 73 can also be a rubber airbag installed between the front bracket 21 and the rear bracket 22. The rubber airbag is filled with fluid medium. When the vehicle hits the rear bracket 22, the rear bracket 22 is displaced to press the rubber airbag, which can also drive the fluid medium in the rubber airbag to flow into the first cylinder 71, and promote the two first piston rods 72 to extend out, which can also achieve the effect of triggering the fire blanket 31 to pop out. The installation position of the rubber airbag can be fixed on the front bracket 21 by the support frame and abut against the rear bracket 22, or embedded in the buffer pad 24, or other parts that can be deformed when the rear bracket 22 is hit, which is not limited here.

[0092] In addition, considering that the front collision of the collision vehicle against the crash cushion is less common, most of the collisions are lateral collisions, such as the rear vehicle driver finds the crash cushion and turns but cannot completely avoid the collision, so that the rear vehicle only collides with part of the rear support 22 and stops at the side of the crash cushion, which will cause the fire blanket 31 to be unable to accurately eject to the collision vehicle, affecting the rescue efficiency.

[0093] Therefore, in a feasible embodiment, referring to Figure 4 and Figure 6 , the storage box 4 is hinged to the front support 21, and the hinge shaft thereof is vertically arranged, and the firing locking mechanism further comprises a turning assembly for driving the storage box 4 to rotate to one end of the rear support 22 when the rear vehicle collides with the one end of the rear support 22.

[0094] The turning assembly comprises:

[0095] The lateral movable members 9 are provided in two and arranged on both sides of the lock cylinder 51, the fixed parts of the lateral movable members 9 are fixedly connected below the front support 21, the movable parts abut against the edges on both sides of the one end of the storage box 4 away from the rear support 22, the lateral movable members 9 are connected with the trigger assembly, and when the trigger assembly detects that the vehicle collides with the rear support 22, the lateral movable members 9 are simultaneously or delayedly driven to work; and when the trigger member 73 detects that the vehicle collides with one end of the rear support 22, the lateral movable members 9 at the opposite end are controlled to work.

[0096] In a specific arrangement, the lateral movable members 9 can be the combination of the second cylinder body and the second piston rod as described above, or can be the rubber air bag as described above, and it is only required that the left lateral movable member 9 is communicated with the right trigger member 73, and the right lateral movable member 9 is communicated with the left trigger member 73.

[0097] Therefore, when the rear vehicle collides with one end of the rear support 22, such as the left end of the rear support 22, the left trigger member 73 first responds, and the fluid medium stored therein flows to the right lateral movable member 9, so that the movable part of the right lateral movable member 9 pushes the right side of the storage box 4 to overturn on the front support 21, and further causes the opening of the storage box 4 to rotate to the left and point to the bottom of the chassis of the collision vehicle. Even the right trigger member 73 also responds at the same time, but the fluid medium delivered by the left trigger member 73 to the right lateral movable member 9 is more, so that the pushing displacement of the right lateral movable member 9 to the storage box 4 is greater than that of the left lateral movable member 9 to the storage box 4, and the posture of the opening of the storage box 4 deflected to the left can still be ensured.

[0098] And, it needs to be clear that the lateral moving member 9 on the left and right side needs to respond to the first cylinder 71 first, that is, it needs to control the storage box 4 to turn first, and then eject the fire blanket 31. The lateral moving member 9 can also be connected with the first cylinder 71, and a one-way valve is arranged in the connecting pipeline to allow the fluid medium in the lateral moving member 9 to flow into the first cylinder 71. In order to achieve the delay effect, the pipeline for connection can be set to a certain length to prolong the flow time of the fluid medium in the pipeline, so that the lateral moving member 9 drives the storage box 4 to turn to the right position. In addition, the trigger member 73 located in the middle of the rear support 22 can be connected with the two lateral moving members 9 on both sides through a flow divider, or can be directly connected with the first cylinder 71 through an extension pipe, as long as the above-mentioned delay effect is met.

[0099] In order to ensure that the fire blanket 31 can have a large initial kinetic energy storage, referring to Figure 4 、 Figure 5 and Figure 6 , the aforementioned force storage mechanism comprises:

[0100] a force storage plate 41, which is fixed to one end of the ejection rod 5 close to the front support 21, and is specifically located at the lower end surface of the storage box 4.

[0101] a guide rod 42, which is provided in plurality, and one end is fixed to one of the force storage plate 41 and the storage box 4, and the other end is slidingly penetrating the other one of the force storage plate 41 and the storage box 4. In this embodiment, the guide rod 42 penetrates the force storage plate 41 and is arranged in the same length as the opening direction of the storage box 4. Multiple guide rods 42 are arranged parallel to the ejection rod 5 and are equally spaced on both sides of the ejection rod 5.

[0102] a force storage spring 43, which is sleeved on the guide rod 42 and has both ends abutting against the force storage plate 41 and the storage box 4 respectively; and

[0103] a buffer plate 44, which is installed on the storage box 4 and located on the side of the force storage plate 41 close to the front support 21, and when the ejection rod 5 is ejected, the force storage plate 41 is brought into collision with the buffer plate 44 to make the middle zone counterweight head 311 disengage from the ejection rod 5. The buffer plate 44 is provided with two plates and is arranged on both sides of the ejection rod 5, and corresponds to the two sides of the force storage plate 41. The buffer plate 44 itself has a certain buffering performance, such as being made of compressible rubber body or being elastically installed on the storage box 4, so that the kinetic energy of the ejection rod 5 can be fully utilized and converted into the kinetic energy of the middle zone counterweight head 311.

[0104] And, the free end of the ejection rod 5 is connected with an upward extending extension 53, the middle area counterweight head 311 is installed on the extension 53, the lower end surface of the storage box 4 is provided with a long slot 45 arranged along the length direction of the ejection rod 5, and the extension 53 is slidingly arranged in the long slot 45; meanwhile, a protective cover (not shown in the figure) of the shielding force storage mechanism should be fixedly connected below the storage box 4, so as to avoid that external sundries reduce the conversion rate of potential energy to kinetic energy of the force storage mechanism.

[0105] Thus, by means of the arrangement of the force storage plate 41, more number of force storage springs 43 can be installed on the ejection rod 5, the stored energy is improved, once the lock hook 62 releases the locking of the lock cylinder 51, the compression deformation force of the plurality of force storage springs 43 pushes the force storage plate 41 to drive the ejection rod 5 to pop out in the direction away from the front support 21, so as to realize the conversion from the elastic potential energy of the force storage spring 43 to the kinetic energy of the ejection rod 5; when the ejection rod 5 moves to the state that the force storage plate 41 hits the buffer plate 44, the ejection rod 5 is limited, the middle area counterweight head 311 is separated from the extension 53 on the free end of the ejection rod 5, and continues to fly forward, meanwhile, by means of the connection of the elastic rod 313 to the two side area counterweight heads 312, the fire blanket 31 stored in the storage box 4 can be laid to the rear of the rear support 22 in the unfolded posture.

[0106] Alternatively, in other feasible embodiments, the ejection device can directly use the existing high-cost electromagnetic ejector, pneumatic ejector and the like, and only the middle area counterweight head 311 needs to be installed to the output end of the corresponding ejector. Embodiment two

[0107] The embodiment of the application discloses a new energy vehicle fireproof anti-collision buffer vehicle.

[0108] The trigger assembly comprises:

[0109] The impact sensor is used for detecting whether a vehicle impacts the rear support 22, and specifically can be a pressure sensor installed on the rear support 22 or in the buffer pad 24, or a displacement sensor on the front support 21. Considering the implementation cost, a patch type pressure sensor can be selected and attached between the rear support 22 and the buffer pad 24, and at least three are arranged along the length direction of the rear support 22 and distributed in the left side area, the middle area and the right side area of the rear support 22.

[0110] The electromagnet is in control connection with the impact sensor, and is energized when the impact sensor detects that a vehicle impacts; the electromagnet is installed on the front support 21 and located between the two long rod sections of the folding rod 61; and

[0111] The repulsion magnet is installed on the inner wall of the end of the folding rod 61 away from the lock cylinder 51, and the magnetic pole close to the electromagnet is the same as the magnetic pole of the electromagnet after energization.

[0112] Correspondingly, in another possible embodiment, the steering assembly is also a combination of two groups of electromagnets and repulsion magnets, the two groups of lateral moving members 9 are distributed on both sides of the hinge part of the receiving box 4 and are installed on the front support 21, and the impact sensor on the right side of the rear support 22 is connected with the control of the electromagnet between the two folding rods 61 and the control of the electromagnet on the left side; the impact sensor on the left side is connected with the control of the electromagnet between the two folding rods 61 and the control of the electromagnet on the right side.

[0113] Therefore, when the rear vehicle hits the rear support 22, which is detected by any impact sensor, the electromagnets between the two folding rods 61 can be controlled to be powered and magnetized, and the long rod sections of the two folding rods 61 are driven to move away from each other, so that the locking hook 62 is unlocked from the shackle 52, and the fire blanket 31 is ejected under the action of the force storage mechanism. Specifically, when the rear vehicle hits one side of the rear support 22, for example, hits the left side of the rear support 22, which is detected by the impact sensor on the left side, at this time, the electromagnet on the right side of the front support 21 is powered, and the receiving box 4 is deflected to the left on the front support 21 through the magnetic repulsion between the electromagnet and the repulsion magnet on the receiving box 4, and then the electromagnet between the two folding rods 61 on the front support 21 is powered, which unlocks the locking cylinder 51, thereby achieving the effect that the fire blanket 31 is ejected to the left side and under the chassis of the rear collision vehicle.

[0114] Therefore, it also needs to be clearly stated that if the steering assembly is provided, the electromagnets between the two folding rods 61 need to be powered and worked after the electromagnets on both sides, so that the receiving box 4 is rotated and then the fire blanket 31 is ejected.
