Description

Technical Field

[0001] The present invention relates to the technical field of automobile chassis, and in particular to a new energy automobile chassis LWRT board with flame retardant effect and a processing technology thereof. Background Art

[0002] When the car is moving, some new energy vehicles with lower chassis are prone to scratches, stone splashing, etc., and the battery of the new energy vehicle is installed on the upper side of the chassis. When the chassis is scratched more seriously, it is easy to cause the battery of the new energy vehicle to overheat and burn or explode. This requires the use of the car chassis LWRT plate for protection.

[0003] Existing automobile chassis guards generally use PVC chassis devices. The PVC chassis armor is heavier overall. When the chassis of new energy vehicles is scratched, causing the battery to overheat, the PVC chassis armor is prone to melting and corrosion, thereby causing damage to the chassis of the vehicle. Summary of the invention

[0004] In order to improve the problem that the chassis of the new energy vehicle mentioned above is scratched, which causes the battery to overheat, and the chassis armor of PVC material is prone to melting, corrosion, etc., which further causes damage to the chassis of the vehicle, the present invention provides a new energy vehicle chassis LWRT board with flame retardant effect and a processing technology.

[0005] The present invention provides a new energy vehicle chassis LWRT board with flame retardant effect and a processing technology, which adopts the following technical solutions: A flame-retardant LWRT plate for a new energy vehicle chassis comprises a plate body, wherein arc-shaped through grooves are provided on both sides of the top of the plate body, and blocking members are slidably arranged inside the arc-shaped through grooves, connecting strips are provided on both sides of the left and right sides of the plate body, a flame-retardant layer is applied to the side of the plate body, and a protective plate is fixedly arranged on the lower side of the plate body.

[0006] Through the above technical solution, it is convenient to provide double protection for the chassis of new energy vehicles, thereby reducing the hazards caused by fire in new energy vehicles, and can prevent friction between cables and wires, reducing the possibility of fire in new energy vehicles.

[0007] Optionally, in the above-mentioned flame-retardant new energy vehicle chassis LWRT board, the shape of the board body is L-shaped, and the board body is a composite material formed by melting glass fiber and polypropylene, and the mixing ratio of glass fiber to polypropylene is 2:1.

[0008] Through the above technical scheme, the board made of glass fiber and polypropylene has excellent flame retardant properties, high specific strength, low thermal conductivity, and high bending strength and impact resistance.

[0009] Optionally, in the above-mentioned flame-retardant new energy vehicle chassis LWRT plate, limiting grooves are provided on the front and rear sides of the inner wall of the arc-shaped through groove, and the blocking member includes a center-shaped block, and the side surfaces of the center-shaped block are respectively slidably connected to the arc-shaped through groove and the inner portion of the limiting groove, and an L-shaped groove is provided inside the center-shaped block, and an L-shaped strip is slidably provided inside the L-shaped groove.

[0010] Through the above technical solution, the L-shaped bar can be used to drive the insertion rod to move upward, so as to quickly release the fixation between the arc-shaped through groove and the middle-shaped block, and then quickly adjust the middle-shaped block inside the arc-shaped through groove.

[0011] Optionally, in the above-mentioned flame-retardant new energy vehicle chassis LWRT plate, a compression spring is fixedly connected to the upper side of the L-shaped strip, the top end of the compression spring is fixedly connected to the upper side of the vertical slot of the L-shaped slot, and an insertion rod is fixedly arranged on the lower side of the horizontal strip of the L-shaped strip. A plurality of adjustment grooves are provided on the lower side of the front limit slot, and a plurality of adjustment grooves are equidistantly arranged in an arc shape on the lower side of the two front limit slots, and the bottom end of the insertion rod extends to the lower side of the L-shaped slot and contacts the inside of the adjustment slot.

[0012] Through the above technical solution, it is convenient to move the middle-shaped block to different areas inside the arc-shaped through groove by inserting the insertion rod into the inner walls of different adjustment grooves, thereby facilitating the arrangement of cables and wires passing through the plate body and reducing friction between the cables and wires.

[0013] Optionally, in the above-mentioned flame-retardant new energy vehicle chassis LWRT board, the flame-retardant layer is sprayed on the upper side of the board body with aluminum pigment with a thickness of 1 mm.

[0014] Through the above technical solution, aluminum pigments can quickly absorb and disperse heat, thereby quickly reducing the temperature of surrounding objects and preventing the spread of fire. Aluminum pigments have a high melting point and reflective properties, which can effectively reflect and block heat. At the same time, aluminum pigments are good oxygen barriers and can reduce the duration of flame combustion reactions.

[0015] Optionally, in the above-mentioned flame-retardant new energy vehicle chassis LWRT plate, the protective plate is made of highly flame-retardant sponge, and a plurality of corrugated grooves are provided on the lower side of the protective plate.

[0016] Through the above technical scheme, the wavy groove can evenly disperse the heat emitted by the battery on the upper side of the car chassis inside the protective plate, reducing the possibility of car combustion. In addition, the highly flame-retardant sponge can quickly undergo chemical reactions when encountering a fire, producing a large amount of inert gas, forming a flame-retardant barrier to effectively isolate the fire source and prevent the fire from spreading.

[0017] Optionally, in the above-mentioned flame-retardant new energy vehicle chassis LWRT plate, the connecting strip includes two long strips, the two long strips are made by integrally molding with the plate body through a mold, and three installation grooves are opened on the upper side of the two long strips, and fixing bolts are placed inside the installation grooves.

[0018] Through the above technical solution, the fixing bolts can slide inside the mounting grooves by providing the mounting grooves, thereby facilitating fixing the plate body on the automobile chassis with partial opening errors.

[0019] Another technical solution proposed by the present invention is a processing technology of a flame retardant new energy vehicle chassis LWRT board, comprising the following steps: S101: heating and melting glass fiber and polypropylene, adjusting to a suitable ratio, adding them into a mold to cool and fix them into shape, and finally taking them out and placing them for future use; S102: pouring aluminum chips into a ball mill by using a ball milling method, crushing the aluminum chips into aluminum powder by using steel balls in the ball mill, then mixing the aluminum powder with paint into a slurry to form aluminum paint, and finally spraying the aluminum paint on the side of the plate by a paint sprayer; S103: After mixing the foamed sponge with the flame retardant, the sponge is foamed, and then the foamed high flame retardant sponge is cut into a suitable size and fixed to the lower side of the plate body by glue; finally, the one-piece formed plate body and two long strips are fixed to the lower side of the car chassis by fixing bolts, so that the plate body can be assembled on the chassis of the new energy vehicle.

[0020] In summary, the present invention includes at least one of the following beneficial effects: the plate made of glass fiber and polypropylene has excellent flame retardant properties, high specific strength, low thermal conductivity, and high bending strength and impact resistance, so that when the chassis is scratched, the impact force exerted on the chassis can be cushioned by the plate; at the same time, the aluminum pigment has a high melting point, can quickly absorb and disperse heat, and reduce the persistence of flame combustion, providing double protection for the chassis of new energy vehicles, thereby reducing the hazards of fire in new energy vehicles.

[0021] By moving the two L-shaped bars upwards respectively, squeezing the compression springs, and moving the insertion rod out of the adjustment slot, the centering block is released, and the centering block is slid to a suitable position in the arc-shaped slot according to the number of cables and wires. The L-shaped bar is loosened, and the L-shaped bar drives the insertion rod to move into the adjustment slot through the compression spring, and the centering block is fixed. The wires and cables passing through the chassis armor are classified and fixed together to prevent friction between the cables and wires, thereby reducing the possibility of fire in new energy vehicles.

[0022] The chassis is installed between the car chassis and the board body through a protective plate made of highly flame-retardant sponge material. The highly flame-retardant sponge can undergo a chemical reaction when encountering a fire to produce inert gas, forming a flame-retardant barrier to effectively isolate the fire source and prevent the fire from spreading. At the same time, the protective plate with wavy grooves can evenly disperse the heat transmitted from the car chassis to the board body through the protective plate, thereby protecting the car chassis and further reducing the harm caused by new energy vehicles.

The insertion rod 305 is driven upward by the L-shaped strip 303 to quickly release the fixation between the arc-shaped through groove 2 and the center-shaped block 301, and then the center-shaped block 301 can be quickly adjusted inside the arc-shaped through groove 2.

[0029] See the attached drawings in the specification Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A compression spring 304 is fixedly connected to the upper side of the L-shaped bar 303, and the top of the compression spring 304 is fixedly connected to the upper side of the vertical groove of the L-shaped groove 302. A plug rod 305 is fixedly arranged on the lower side of the horizontal bar of the L-shaped bar 303. A plurality of adjustment grooves 202 are opened on the lower side of the front limit groove 201. The plurality of adjustment grooves 202 are opened in an arc shape at equal distances on the lower side of the two front limit grooves 201. The bottom end of the plug rod 305 extends to the lower side of the L-shaped groove 302 and contacts the inside of the adjustment groove 202. By inserting the plug rod 305 into the inner walls of different adjustment grooves 202, it is convenient to move the middle-shaped block 301 to different areas inside the arc through groove 2, thereby facilitating the arrangement of cables and wires passing through the plate body 1 and reducing the friction between the cables and wires.

[0030] See the attached drawings in the specification Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The flame retardant layer 5 is sprayed on the upper side of the plate body 1 with aluminum pigment having a thickness of 1 mm. The aluminum pigment can quickly absorb and disperse heat, thereby quickly reducing the temperature of surrounding objects and preventing the spread of fire.

At the same time, the aluminum pigment is a good oxygen barrier, which can reduce the persistence of the flame combustion reaction.

[0031] See the attached drawings in the specification Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The material of the protective plate 6 is made of highly flame-retardant sponge. A plurality of wave grooves 601 are provided on the lower side of the protective plate 6.

By setting the mounting grooves 402, the fixing bolts 403 can slide inside the mounting grooves 402, thereby facilitating fixing the plate body 1 on the automobile chassis with errors in some openings.

[0033] In summary: the plate body 1 made of glass fiber and polypropylene has excellent flame retardant properties, high specific strength, low thermal conductivity, and high bending strength and impact resistance. When the chassis is scratched, the plate body 1 can cushion the impact force on the chassis. At the same time, aluminum pigment is sprayed on the side of the plate body 1, and the aluminum pigment has a high melting point. It can quickly absorb and disperse heat and reduce the duration of flame combustion. By providing double protection for the chassis of new energy vehicles, the hazards of fire in new energy vehicles are reduced.

[0034] By moving the two L-shaped bars 303 upwards respectively, the compression spring 304 is squeezed, and the insertion rod 305 is moved out from the inside of the adjustment groove 202, thereby releasing the fixed state of the center-shaped block 301. Secondly, according to the number of cables and wires, the center-shaped block 301 is slid to a suitable position inside the arc-shaped through groove 2, and then the L-shaped bar 303 is loosened, so that the L-shaped bar 303 drives the insertion rod 305 to reset downward through the rebound force of the compression spring 304, and moves to the inside of the adjustment groove 202 to fix the center-shaped block 301. Then, the wires and cables passing through the chassis armor can be classified and fixed together to prevent friction between the cables and wires, thereby reducing the possibility of fire in new energy vehicles.

[0035] The chassis is installed between the automobile chassis and the plate body 1 through a protective plate 6 made of highly flame-retardant sponge material. The highly flame-retardant sponge can quickly undergo a chemical reaction when encountering a fire, producing a large amount of inert gas, forming a flame-retardant barrier to effectively isolate the fire source and prevent the fire from spreading. At the same time, the protective plate with a wavy groove 601 can evenly disperse the heat transmitted from the automobile chassis to the plate body 1 through the protective plate 6, thereby protecting the automobile chassis and further reducing the harm caused by new energy vehicles.

[0036] In order to better demonstrate a flame retardant LWRT board for a new energy vehicle chassis, this embodiment now proposes a processing technology for a flame retardant LWRT board for a new energy vehicle chassis, including the following steps: Step 1: Heat and melt the glass fiber and polypropylene, adjust to a suitable ratio, add them into a mold to cool and fix them into shape, and finally take them out and set them aside for later use.

[0037] Step 2: Pour aluminum chips into a ball mill by using a ball milling method, use the steel balls inside the ball mill to crush the aluminum chips into aluminum powder, then mix the aluminum powder with paint to form a slurry to form aluminum paint, and finally spray the aluminum paint on the side of the plate 1 through a paint sprayer.

[0038] Step three: After mixing the foamed sponge with the flame retardant, the sponge is foamed, and then the foamed high flame retardant sponge is cut into a suitable size and fixed to the lower side of the plate body 1 by glue; finally, the plate body 1 is fixed to the lower side of the car chassis by fixing bolts 403 as an integrally formed plate body 1 and two long strips 401.
