[0016] Compared with the prior art, the present invention provides a van chassis for new energy vehicles, which has the following beneficial effects:

[0017] 1. The van chassis of the new energy vehicle drives the L-shaped slide plate to slide by starting the cylinder. The L-shaped slide plate slides in the guide rail, driving the sliding wheel at the bottom to move to the appropriate position to support the rear part of the vehicle, effectively improving the stability of the vehicle.

[0018] 2. The van chassis of the new energy vehicle is blocked by the heat dissipation holes, so that the heat inside the battery storage box cannot be discharged in time, causing the easily expandable gas in the piston cylinder to expand, pushing the piston plate upward, and the piston plate pushes the push rod on the top. The push rod pushes the first inclined plate to rotate, driving the ring to slide on the telescopic transmission rod, conflicting with the circular plate, and pushing the telescopic transmission rod to slide in the inner direction of the cylinder, thereby driving the connecting plate to slide and push the two connecting rods. The two connecting rods push the two clutch blocks to slide in the outer direction of the rectangular frame under the limit of the rectangular frame, thereby moving the two clutch blocks away from each other, stretching the first elastic member, conflicting with the anti-skid groove of the rotating cylinder, and causing the clutch block to rotate with the cylinder, thereby driving the connecting rod and the connecting plate. , the telescopic transmission rod rotates synchronously to automatically obtain power from the cooling fan, and then the telescopic transmission rod drives the disc to rotate, and the disc drives the slider on the surface to make eccentric motion inside the sliding frame, so that the sliding frame makes horizontal reciprocating motion, driving the strip plates on both sides to make reciprocating motion, and then driving the brush plate on the U-shaped guide plate to slide back and forth on the cooling holes, to remove dust and other impurities blocked on the cooling holes, and cooperate with the wind force of the cooling fan to clean the dust to the outside of the battery storage box, so that the dust on the cooling holes can be automatically removed, which is helpful for the internal heat dissipation of the battery storage box without manual cleaning, and then helps to make the electrical components inside the battery storage box perform more stable performance, making the vehicle more stable during driving.

[0019] 3. After the dust on the heat dissipation holes of the van chassis of the new energy vehicle is cleared, the temperature inside the battery storage box slowly decreases. At this time, the temperature of the easily expandable gas in the piston cylinder slowly decreases, and then the piston plate slowly drops, thereby pulling the push rod on the top to rotate the first inclined plate and pulling the ring. The ring slowly reduces the thrust on the circular plate, and the two clutch blocks are eventually separated from the inner wall of the cylinder under the reset force of the first elastic member, so that they no longer rotate with the cylinder, and then can automatically control the rotation of the telescopic transmission rod, so that the two brush plates no longer clean the heat dissipation holes, so that the air circulation inside the battery storage box is better, and automatic control can be achieved without manual cleaning.

[0020] 4. The box-type chassis of the new energy vehicle, while the telescopic transmission rod drives the disc to rotate, controls the sliding of the two strip plates, and drives the rectangular plate to move back and forth, thereby driving the second inclined plate at the bottom to rotate back and forth, so that the first sliding rod slides up and down reciprocatingly in the first sealing tube, thereby driving the first piston to repeatedly do piston movement, so that the first sealing tube repeatedly inhales air through the suction pipe, squeezes it out from the intake hose 3401, then enters the cavity of the brush plate, and then squeezes it out from the air outlet of the brush plate, and blows away the stubborn dust on the heat dissipation holes by jet, which helps to make the dust cleaning effect on the heat dissipation holes better and faster.

[0021] 5. The van chassis of the new energy vehicle drives the cam to rotate at the same time as the second rotating rod rotates. When the protruding part of the cam rotates to the second sliding rod, the second sliding rod is pressed downward, driving the second piston downward. When the second sliding rod moves downward, the second elastic member is compressed by the round block. Then, when the protruding part of the cam does not conflict with the second sliding rod, the second elastic member automatically resets the second piston upward. With this reciprocating operation, the second sealing cylinder can reciprocately draw lubricating oil from the storage barrel through the oil extraction pipe, and then squeeze out a small amount of lubricating oil from the oil outlet pipe to spray onto the transmission shaft. , which helps to reduce the friction of the transmission shaft, making the vehicle perform more stably and ensuring smooth power transmission; at the same time, when the second rotating rod rotates, it will also drive the half gear to rotate and mesh with the tooth groove in the bar frame. Because the bar frame is guided by the limit of the slide plate through the L-shaped guide plate, the bar frame makes horizontal reciprocating motion, thereby driving the cleaning brush to brush back and forth on the ventilation holes on the battery storage box, which helps to automatically clean the dust on the back of the cooling fan, helps to make the air circulation inside the battery storage box better, and the chassis performs more stable performance during vehicle driving.

DETAILED DESCRIPTION

[0038] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0039] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0041] In the present invention, after the vehicle stops on the road, when encountering a sloped section, the parking space is heavy, and the support of only one set of wheels is poor, which can easily cause the front of the vehicle to detach from the ground. At this time, the cylinder 9 can be started to drive the L-shaped slide plate 10 to slide, and the L-shaped slide plate 10 slides in the guide rail 11, driving the sliding wheel 12 at the bottom to move to a suitable position, supporting the rear part of the vehicle, and effectively improving the stability of the vehicle; the cooling fan 6 inside the battery storage box 5 can dissipate the heat of the electrical components inside the battery storage box 5, and when the cooling fan 6 rotates, it can also drive the first rotating rod 13 to rotate. The first rotating rod 13 can drive the second rotating rod 15 to rotate synchronously through the synchronous belt 16, and the bearing seat 14 can provide stable support for the second rotating rod 15 when it rotates. When the second rotating rod 15 rotates, it will also drive the automatic control component 17 to rotate synchronously.

[0042] Example 2: Reference Figure 1-Figure 15 , which is basically the same as the first embodiment, and further, the second rotating rod 15 passes through the battery storage box 5 and is rotatably connected to the battery storage box 5, the automatic control component 17 includes a cylinder 1701, the surface of the second rotating rod 15 is fixedly connected to the cylinder 1701, the bottom inner wall of the battery storage box 5 is fixedly connected to a piston cylinder 1702, and the internal piston of the piston cylinder 1702 is connected to a piston plate 1703.

[0044] In the present invention, since the vehicle is used for a long time, the chassis part is close to the ground, and the dust on the ground will be adsorbed on the heat dissipation holes 7 for a long time, and the heat dissipation holes 7 will be blocked over time, resulting in the heat inside the battery storage box 5 cannot be discharged in time, which easily causes the temperature of the electrical components inside the battery storage box 5 to rise, and easily causes a short circuit. At this time, the heat inside the battery storage box 5 is increasing. After the internal temperature rises to a certain degree, the expandable gas in the piston cylinder 1702 expands and pushes the piston plate 1703 upward. The piston plate 1703 pushes the top push rod 1704, and the push rod 1704 pushes the first inclined plate 1705 to rotate.

[0045] A telescopic transmission rod 20 is passed through the surface of the bearing plate 19, and the telescopic transmission rod 20 is rotatably connected to the bearing plate 19. A circular plate 21 is fixedly connected to the surface of the telescopic transmission rod 20.

[0047] Two sets of connecting rods 1708 are hinged on one side of the connecting plate 1707 away from the telescopic transmission rod 20. The two sets of connecting rods 1708 are symmetrically arranged with the center line of the connecting plate 1707 as the symmetry axis.

[0049] In the present invention, when the connecting plate 1707 slides, it will push the two connecting rods 1708, and the two connecting rods 1708 will push the two clutch blocks 1709 to slide toward the outside of the rectangular frame 1710 under the limit of the rectangular frame 1710, so that the two clutch blocks 1709 move away from each other, stretch the first elastic member 1711, and interfere with the anti-slip groove of the rotating cylinder 1701, so that the clutch block 1709 rotates with the cylinder 1701, thereby driving the connecting rod 1708, the connecting plate 1707, and the telescopic transmission rod 20 to rotate synchronously, automatically obtaining the power of the cooling fan 6, and then the telescopic transmission rod 20 drives the disc 22 to rotate, and the disc 22 drives the slider 23 on the surface to make eccentric motion inside the sliding frame 24.

[0050] A guide groove plate 28 is fixedly connected to the inner wall of the battery storage box 5 on the side away from the cooling fan 6. The U-shaped guide plate 27 penetrates the guide groove plate 28 and is slidably connected to the guide groove plate 28. The end of the U-shaped guide plate 27 away from the strip plate 25 is fixedly connected to a brush plate 29. Two groups of brush plates 29 are symmetrically arranged. A cavity is opened inside the brush plate 29. An air outlet hole is opened on the surface of the brush plate 29 near the heat dissipation hole 7. A connecting pipe 30 is fixedly connected between the two groups of brush plates 29. A second inclined plate 31 is hinged at one end of the rectangular plate 26 away from the strip plate 25, and a first sliding rod 32 is hinged at one end of the second inclined plate 31 away from the rectangular plate 26.

[0051] In the present invention, under the action of the guide groove plate 28, the U-shaped guide plate 27 can only slide horizontally in the guide groove plate 28, and then when the disc 22 drives the slider 23 to slide in the sliding frame 24, the sliding frame 24 can make a horizontal reciprocating motion, thereby driving the strip plates 25 on both sides to make a reciprocating motion, and then driving the brush plate 29 on the U-shaped guide plate 27 to slide reciprocatingly on the heat dissipation hole 7, so as to remove dust and other impurities blocked on the heat dissipation hole 7, and cooperate with the wind force of the heat dissipation fan 6 to clean the dust to the outside of the battery storage box 5, so that the dust on the heat dissipation hole 7 can be automatically removed, which is helpful for the internal heat dissipation of the battery storage box 5 without manual cleaning, and then helps to make the electrical components inside the battery storage box 5 play a more stable performance, so that the vehicle can be driven The process is more stable; when the dust on the heat dissipation hole 7 is cleared, the temperature inside the battery storage box 5 slowly decreases, and at this time, the temperature of the easily expandable gas in the piston cylinder 1702 slowly decreases, and then the piston plate 1703 slowly drops, thereby pulling the top push rod 1704 to rotate the first inclined plate 1705, pulling the ring 1706, and the ring 1706 slowly reduces the thrust on the circular plate 21, and the two clutch blocks 1709 are finally separated from the inner wall of the cylinder 1701 under the reset force of the first elastic member 1711, so that they no longer rotate with the cylinder 1701, and then can automatically control the rotation of the telescopic transmission rod 20, so that the two brush plates 29 no longer clean the heat dissipation holes 7, so that the air circulation inside the battery storage box 5 is better.

[0052] Example 3: Reference Figure 1-Figure 14 , which is basically the same as the first embodiment, and further, a first sealing cylinder 33 is fixedly connected to the inner wall of the bottom of the battery storage box 5 near the heat dissipation hole 7, and the internal piston of the first sealing cylinder 33 is connected to the first piston 34, the first piston 34 is fixedly connected to the first sliding rod 32, the first sliding rod 32 passes through the first sealing cylinder 33, and is slidably connected to the first sealing cylinder 33, an air intake hose 3401 is fixedly connected between the first sealing cylinder 33 and the cavity of the brush plate 29, an air intake pipe 35 is fixedly connected to the bottom of the first sealing cylinder 33, a cam 36 is fixedly connected to the surface of the second rotating rod 15 near the inner wall of the battery storage box 5, and a second sealing cylinder 37 is fixedly connected to the inner wall of the bottom of the battery storage box 5 near the heat dissipation fan 6.

[0053] In the present invention, while the telescopic transmission rod 20 drives the disc 22 to rotate, that is, in the process of controlling the brush plate 29 to clean the heat dissipation hole 7, it is inevitable that some agglomerated and stubborn dust will be adsorbed on the heat dissipation hole 7, and the two strip plates 25 will slide while driving the rectangular plate 26 to reciprocate, thereby driving the second inclined plate 31 at the bottom to reciprocate, so that the first sliding rod 32 slides up and down in the first sealing cylinder 33, thereby driving the first piston 34 to repeatedly do piston movement, so that the first sealing cylinder 33 is sucked by air. Tube 35 repeatedly inhales air, which is squeezed out from the air intake hose 3401, then enters the cavity of the brush plate 29, and is squeezed out from the air outlet of the brush plate 29, thereby jetting air to remove stubborn dust on the heat dissipation holes 7, which helps to make the dust cleaning effect on the heat dissipation holes 7 better and faster (it should be noted that one-way valves are installed inside the air intake hose 3401 and the air intake pipe 35, in order to prevent the gas from being squeezed out from the air intake pipe 35 when squeezing out the gas, and to prevent the gas from being sucked in from the air intake hose 3401 when extracting the gas).

[0054] The internal piston of the second sealing cylinder 37 is connected to the second piston 38, and the top of the second piston 38 is fixedly connected to the second sliding rod 39, the second sliding rod 39 passes through the second sealing cylinder 37 and is slidably connected to the second sealing cylinder 37, the surface of the second sliding rod 39 is fixedly connected to a round block 40, and the surface of the second sliding rod 39 is sleeved with a second elastic member 41, and the two ends of the second elastic member 41 are respectively abutted against the round block 40 and the second sealing cylinder 37, and the top of the second sliding rod 39 is abutted against the cam 36, and the outer surface of the battery storage box 5 close to the cooling fan 6 is provided with ventilation holes corresponding to the cooling fan 6.

[0055] A half gear 42 is fixedly connected to the surface of the second rotating rod 15 near the outside of the battery storage box 5, and a bar frame 43 is sleeved on the outside of the half gear 42. Tooth grooves 44 that mesh with the half gear 42 are opened on the inner walls on both sides of the bar frame 43, and a slide plate 45 is fixedly connected to the outer surface of the battery storage box 5 near the bar frame 43, and an L-shaped guide plate 46 is fixedly connected to the surface of the bar frame 43. The end of the L-shaped guide plate 46 away from the bar frame 43 is slidably connected in the L-shaped guide plate 46, and a cleaning brush 47 is fixedly connected to the top surface of the bar frame 43. A storage barrel 48 is fixedly connected to the inner wall of the bottom of the battery storage box 5 near the second sealing cylinder 37, and lubricating oil is provided inside the storage barrel 48. An oil extraction pipe 49 is fixedly connected between the storage barrel 48 and the second sealing cylinder 37, and an oil outlet pipe 50 is fixedly connected to the bottom of the second sealing cylinder 37, and the direction of the oil outlet pipe 50 is in the direction of the transmission shaft 4.

[0056] In the present invention, when the second rotating rod 15 rotates, the cam 36 is driven to rotate at the same time. When the protruding portion of the cam 36 rotates to the position where the second sliding rod 39 is located, the second sliding rod 39 is pressed downward, driving the second piston 38 downward. When the second sliding rod 39 is downward, the second elastic member 41 is compressed by the round block 40. Subsequently, when the protruding portion of the cam 36 does not interfere with the second sliding rod 39, the second elastic member 41 automatically resets the second piston 38 upward. This reciprocating operation enables the second sealing cylinder 37 to reciprocately draw lubricating oil from the storage barrel 48 through the oil extraction pipe 49, and then squeeze out a small amount of lubricating oil from the oil outlet pipe 50 to spray onto the transmission shaft 4, which helps to reduce the friction of the transmission shaft 4, so that the vehicle can exert more stable performance and ensure smooth power transmission. (It should be noted that a one-way valve is installed inside the oil extraction pipe 49 and the oil outlet pipe 50 in order to prevent oil from being extracted from the oil outlet pipe 50 during the oil extraction process and to prevent oil from being squeezed out of the oil extraction pipe 49 during the oil squeezing process); at the same time, when the second rotating rod 15 rotates, it will also drive the half gear 42 to rotate and mesh with the tooth groove 44 in the bar frame 43. Because the bar frame 43 is guided by the L-shaped guide plate 46 under the limiting guide of the slide plate 45, the bar frame 43 makes a horizontal reciprocating motion, thereby driving the cleaning brush 47 to brush back and forth on the ventilation holes on the battery storage box 5, which helps to automatically clean the dust on the back of the cooling fan 6, helps to make the air circulation inside the battery storage box 5 better, and during the driving of the vehicle, the chassis performs a more stable performance.
