Description

Technical Field

[0001] This invention relates to the field of new energy vehicles, and more specifically to a new energy vehicle chassis and its processing system. Background Technology

[0002] A new energy vehicle chassis is a frame structure in electric or hybrid vehicles that supports the vehicle body and various components. It is similar to a traditional car chassis, but due to the different power source, it has some unique characteristics in design and construction. The main difference is that a battery pack is installed on the chassis of a new energy vehicle. The battery pack is the energy storage device for new energy vehicles, typically using lithium-ion batteries or solid-state batteries. It stores electrical energy and provides power to the electric motor. Currently, most new energy vehicle battery packs are installed on the chassis; if a spontaneous combustion accident occurs, it cannot be extinguished in time, posing a threat to the driver's safety. Summary of the Invention

[0003] To overcome the shortcomings of the existing technology, the present invention provides a new energy vehicle chassis and its processing system, which has the advantage of facilitating the timely extinguishing of battery pack fires.

[0004] A new energy vehicle chassis includes a chassis, a battery pack, square holes, a dry powder cylinder, and elastic columns. The battery pack is screwed onto the chassis. Two square holes are provided on each side of the battery pack. Two elastic columns are welded to the bottom of the dry powder cylinder. The elastic columns can be inserted into the square holes. The dry powder cylinder contains dry powder fire extinguishing agent and compressed gas.

[0005] It also includes a pivot, spring I, a rear wheel axle and a front wheel axle. The two pivots are rotatably connected to the chassis, the front wheel axle is slidably connected to the pivot, and the rear wheel axle is slidably connected to the chassis. Both the rear wheel axle and the front wheel axle are provided with cylinders, and four springs I are respectively wound around the corresponding cylinders.

[0006] A processing system for a new energy vehicle chassis includes a convex rib, a lower clamp, a spring II, and a slider. The slider is welded to an upper clamp. Multiple convex ribs are arranged below the upper clamp. The upper clamp is provided with a round shaft. The lower clamp is slidably connected to the round shaft. The spring II is wound around the round shaft. A baffle is provided at the bottom of the round shaft. One end of the spring II is pressed tightly against the lower part of the upper clamp, and the other end of the spring II is pressed tightly against the upper part of the baffle.

[0007] It also includes motor I, side plate and threaded column. Motor I is screwed to the side plate, the threaded column is rotatably connected to the side plate, the threaded column is keyed to the output shaft of motor I, the slider is threaded to the threaded column, and there are inclined surfaces below the upper clamping body and above the lower clamping body.

[0023] like Figure 3-6As shown, this example can facilitate the timely extinguishing of a fire in battery pack 102.

[0024] Since the new energy vehicle chassis includes a chassis 101, a battery pack 102, square holes 108, a dry powder cylinder 201, and elastic columns 204, the battery pack 102 is screwed onto the chassis 101. There are two square holes 108 on each side of the battery pack 102. Two elastic columns 204 are welded to the bottom of the dry powder cylinder 201. The elastic columns 204 can be inserted into the square holes 108. The dry powder cylinder 201 contains dry powder extinguishing agent and compressed gas. The dry powder cylinder 201 can be installed on both sides of the battery pack 102 through the elastic columns 204. When the battery pack 102 catches fire, the compressed gas in the dry powder cylinder 201 is heated, and the dry powder extinguishing agent in the dry powder cylinder 201 can be sprayed and diffused to cover the burning battery pack 102, thus facilitating the timely extinguishing of the fire in the battery pack 102.

[0025] like Figure 3-4 As shown, this example can effectively reduce vibrations during vehicle operation.

[0026] Since the chassis of a new energy vehicle also includes a pivot 103, spring I 104, rear axle 105 and front axle 106, the two pivots 103 are rotatably connected to the chassis 101, the front axle 106 is slidably connected to the pivot 103, and the rear axle 105 is slidably connected to the chassis 101. Both the rear axle 105 and the front axle 106 are provided with cylinders, and four springs I 104 are respectively wound around the corresponding cylinders. Thus, when vibration occurs during driving, the four springs I 104 can compress and absorb the impact of the vibration, thereby facilitating the reduction of vibration during vehicle driving.

[0027] like Figure 7-8 As shown, this example can achieve the effect of increasing the friction between the clamping parts.

[0028] The processing system used in the chassis of new energy vehicles includes a convex rib 304, a lower clamping body 305, a spring II 306, and a slider 308. An upper clamping body is welded to the slider 308. Multiple convex ribs 304 are arranged below the upper clamping body. A round shaft is provided on the upper clamping body. The lower clamping body 305 is slidably connected to the round shaft. The spring II 306 is wound around the round shaft. A baffle is provided at the bottom of the round shaft. One end of the spring II 306 is pressed tightly against the lower part of the upper clamping body, and the other end of the spring II 306 is pressed tightly against the baffle. As a result, the spring II 306 pushes the lower clamping body 305 to move up and down, and the lower clamping body 305 is pressed tightly against the lower part of the upper clamping body. The convex ribs 304 can increase the friction between the upper clamping body and the lower clamping body 305, thereby increasing the friction between the clamping bodies and enabling the clamping bodies to clamp objects more firmly.

[0029] like Figure 3-8As shown, this example allows for easy clamping of the chassis 101.

[0030] Since the processing system used in the new energy vehicle chassis also includes a motor I 301, a side plate 302, and a threaded column 303, the chassis 101 has a side plate 302 on each side. The motor I 301 is screwed to the side plate 302, the threaded column 303 is rotatably connected to the side plate 302, the threaded column 303 is keyed to the output shaft of the motor I 301, and the slider 308 is threaded to the threaded column 303. There are inclined surfaces below the upper clamping body and above the lower clamping body 305, so that the motor I 301 can drive the threaded column 303 to rotate, and the threaded column 303 can drive the slider 308 to move inward. Then, the two sliders 308 drive the upper clamping body and the lower clamping body 305 to move closer to the chassis 101. The inclined surfaces below the upper clamping body and above the lower clamping body 305 facilitate the chassis 101 to enter between the upper clamping body and the lower clamping body 305, thereby achieving the effect of easily clamping the chassis 101 with the clamping body.

[0031] like Figure 3-8 As shown, this example can facilitate the fixation of the clamp and the position of the chassis 101.

[0032] Since the processing system used in the new energy vehicle chassis also includes clamping grooves 109, two clamping grooves 109 are provided below the chassis 101, and inclined surfaces are provided on both sides of the lower clamping body 305, the inclined surfaces of the lower clamping body 305 can allow the lower clamping body 305 to slide into the clamping grooves 109, and the clamping grooves 109 fix the position of the lower clamping body 305, thereby achieving the effect of facilitating the fixing of the clamping body and the position of the chassis 101.

[0033] like Figure 3-8 As shown, this example allows for easy pushing of the elastic column 204 into the L-shaped groove 107.

[0034] Since the processing system used in the new energy vehicle chassis also includes L-shaped grooves 107, semi-circular clamps 202, T-shaped grooves 203 and T-shaped strips 307, the chassis 101 is provided with four L-shaped grooves 107, and T-shaped strips 307 are welded to the top of the two sliders 308. T-shaped grooves 203 are provided on the two semi-circular clamps 202. The T-shaped strips 307 are slidably connected in the T-shaped grooves 203. The semi-circular clamps 202 hold the dry powder cylinder 201. The T-shaped strips 307 are provided with square columns, which are slidably connected to the side plate 302. Thus, the two sliders 308 can push the two semi-circular clamps 202 inward. Thus, the two semi-circular clamps 202 drive the dry powder cylinder 201 and the elastic column 204 to slide inward along the short groove of the L-shaped groove 107, thereby achieving the effect of facilitating the pushing of the elastic column 204 into the short groove of the L-shaped groove 107.

[0035] like Figure 3-8 As shown, this example allows for easy pushing of the elastic post 204 from the L-shaped groove 107 into the square hole 108.

[0036] The processing system used in the chassis of new energy vehicles also includes a hydraulic cylinder 206, a slide 207, and a top plate 208. The top plate 208 is screwed to the top of the two side plates 302. The hydraulic cylinder 206 is screwed to the bottom of the top plate 208. The other end of the hydraulic cylinder 206 is screwed to the slide 207. Two sliding columns are provided above the slide 207. The sliding columns of the slide 207 are slidably connected to the top plate 208. A sliding hole is provided above the semi-circular clamp 202. The two semi-circular clamps 202 are slidably connected to the slide 207. An inclined surface is provided on the elastic column 204. When the semicircular clamp 202 is pushed by the slider 308, it can move inward along the slide 207. The hydraulic cylinder 206 can drive the slide 207 to move forward. The slide 207 then drives the semicircular clamp 202 and the elastic column 204 to move forward together. The inclined surface on the elastic column 204 allows the elastic column 204 to slide into the long groove of the L-shaped groove 107. The elastic column 204 can then enter the square hole 108 along the long groove of the L-shaped groove 107, thus facilitating the pushing of the elastic column 204 from the L-shaped groove 107 into the square hole 108.

[0037] like Figure 7-8 As shown, this example can achieve the effect of fixing the vertical position of the dry powder cylinder 201.

[0038] Since the processing system used in the chassis of new energy vehicles also includes a baffle 205, a baffle 205 is provided above the elastic column 204, and a protrusion is provided below the elastic column 204, when the elastic column 204 is inserted into the square hole 108, the baffle 205 blocks the upper part of the chassis 101 and the protrusion blocks the lower part of the chassis 101, thereby achieving the effect of fixing the vertical position of the dry powder cylinder 201 and preventing the dry powder cylinder 201 from moving up and down.

[0039] like Figure 3-10 As shown, this example allows for easy attachment of the conveyor belt 401 to the base 309.

[0040] Since the processing system used in the chassis of new energy vehicles also includes a conveyor belt 401, a side frame 404, a nut 406, and a through hole 407, the side frame 404 is provided with a through hole 407, and the two side frames 404 are inserted into the base 309 through the through hole 407. The nut 406 is provided below the side frame 404, and the nut 406 threadedly connects the two side frames 404 to the base 309. The conveyor belt 401 is wrapped around the side frame 404, and then the nut 406 fixes the two side frames 404 to the base 309, thereby fixing the position of the conveyor belt 401, thus achieving the effect of easily fixing the conveyor belt 401 to the base 309.

[0041] like Figure 3-10 As shown, this example can achieve the effect of transporting chassis 101 via conveyor belt 401.

[0042] Since the processing system used in the new energy vehicle chassis also includes a rotary drum 402, a convex strip 403, and a motor II 405, the two rotary drums 402 are rotatably connected between the two side frames 404. The motor II 405 is screwed onto the side frame 404. The rotary drum 402 is keyed onto the output shaft of the motor II 405. The rotary drum 402 is provided with a ring of convex strips 403. The convex strips 403 on the rotary drum 402 can increase the friction between the rotary drum 402 and the conveyor belt 401. As a result, the motor II 405 can drive the rotary drum 402 to rotate. As a result, the rotary drum 402 can drive the conveyor belt 401 to move forward. This achieves the effect of transporting the chassis 101 through the conveyor belt 401 and can remove the processed chassis 101 from the processing system.
