Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] See also Figure 1-6One embodiment of the present invention is: a chassis assembly of a new energy vehicle, comprising a suspension body 1, a wheel hub 2 and a buffer shock absorbing mechanism 8, wherein a rubber tire 3 is arranged on the surface of the wheel hub 2, a transmission shaft 4 is fixedly connected to the side of the wheel hub 2, a brake component 5 is arranged on the surface of the transmission shaft 4, a spring expansion joint 6 is arranged at one end of the transmission shaft 4 away from the wheel hub 2, and a universal joint 7 is fixedly connected to one end of the spring expansion joint 6 away from the wheel hub 2; the buffer shock absorbing mechanism 8 comprises a T-shaped frame 81, a spring expansion cylinder 810 and a slide cylinder 811, and the T-shaped frame 81 is rotatably connected to the suspension At the top of the body 1, the inner side of the T-shaped frame 81 is fixedly connected with a rod body 89, the surface of the rod body 89 is fixedly connected with a T-shaped block 82, the end of the T-shaped block 82 away from the rod body 89 is fixedly connected with a telescopic rod 83, the surface of the telescopic rod 83 is sleeved with a buffer spring A84, the end of the telescopic rod 83 away from the T-shaped block 82 is fixedly connected with a connecting block 85, the end of the connecting block 85 away from the telescopic rod 83 is fixedly connected with a support frame 86, the bottom end of the support frame 86 is penetrated and rotatably connected with the transmission shaft 4, and the front end and the rear end of the support frame 86 are fixedly connected with an articulated frame 8 8. Both ends of the spring telescopic cylinder 810 are respectively hingedly connected to the transmission shaft 4 and the inner wall of the wheel hub 2. The number of the spring telescopic cylinder 810 is set to three groups, and the three groups of spring telescopic cylinders 810 are evenly spaced and distributed on the surface of the transmission shaft 4. The three groups of spring telescopic cylinders 810 play a buffering and shock-absorbing effect when the rubber tire 3 and the wheel hub 2 bounce. One end of the slide cylinder 811 is rotatably connected to the rod body 89, and the other end of the slide cylinder 811 is internally slidably connected to a slider 812. The end of the slider 812 away from the slide cylinder 811 is fixedly connected to a slide rod 813. The slide rod One end of 813 away from the slider 812 is hingedly connected to the articulated frame 88, and a buffer spring B814 is arranged on the surface of the slide 811. The number of slides 811 is set to two groups, and the two groups of slides 811 are symmetrical along the transmission shaft 4. When a large obstacle is encountered during driving, causing the rubber tire 3 and the wheel hub 2 to deviate, the slide rod 813 and the slider 812 will slide inside the slide 811, and the buffer spring B814 has the effect of buffering and shock absorption. A lubrication mechanism 9 is arranged inside the slide rod 813, and a smoothing mechanism 10 is arranged on the top of the slider 812.

[0022] When in use, the universal joint 7 is connected to the driving device of the vehicle. During normal driving of the vehicle, the driving device drives the universal joint 7 and the transmission shaft 4 to rotate, and the spring expansion joint 6 plays a lateral buffering and shock absorption. The rotation of the transmission shaft 4 drives the wheel hub 2 and the rubber tire 3 thereon to rotate, thereby driving the vehicle to drive. When the rubber tire 3 drives on an uneven road surface or encounters a smaller obstacle, the vehicle will be bumpy, and the rubber tire 3 and the wheel hub 2 will bounce. At this time, the three sets of spring expansion cylinders 810 play a buffering and shock absorption effect on the jumping of the rubber tire 3 and the wheel hub 2, so that the vibration transmitted to the vehicle body becomes smaller. When a larger obstacle is encountered during driving and the rubber tire 3 and the wheel hub 2 are offset, the slide bar 813 and the slider 812 slide in the slide cylinder 811, and the buffer spring B814 plays a buffering and shock absorption effect in cooperation with the rotation of the T-shaped frame 81. Then, the T-shaped frame 81 is driven to restore, thereby achieving the effect of buffering and shock absorption and resetting, keeping the rubber tire 3 vertical to the ground, enhancing the adhesion between the rubber tire 3 and the ground, and ensuring stable driving of the vehicle.

[0023] See also Figure 1-9On the basis of the above-mentioned embodiment, in another embodiment of the present invention, the lubricating mechanism 9 includes an oil filling pipe 91, an oil storage chamber 92, an oil leakage hole 93, a bracket 94 and an air pressure chamber 98, the oil filling pipe 91 is fixedly connected to the inside of the sliding rod 813, the oil storage chamber 92 is opened inside the sliding block 812, the oil leakage hole 93 is opened on the surface of the sliding block 812, the number of the oil leakage holes 93 is set to six groups, and the six groups of oil leakage holes 93 are evenly spaced on the surface of the sliding block 812, through the six groups of oil leakage holes 93, the lubricating oil in the oil storage chamber 92 can leak to the inner wall of the sliding cylinder 811, the top of the oil filling pipe 91 passes through and is fixedly connected to the oil storage chamber 92, the inside of the oil storage chamber 92 is slidably connected with a closed ring 911, the bracket 94 is fixedly connected to the top of the sliding block 812, the bracket The inner side of 94 is rotatably connected with a rotating shaft 95, and the surface of the rotating shaft 95 is fixedly connected with a roller 96 and an eccentric wheel 97. An air pressure chamber 98 passes through and is fixedly connected to the top of the slider 812. An air bag 99 is arranged at one end of the air pressure chamber 98. The outer wall of the roller 96 is in close contact with the inner wall of the slide 811. The eccentric wheel 97 is close to the air bag 99, and the air bag 99 is in an expanded state in the initial state. When the friction force of the inner wall of the slide 811 is large, the slider 812 slides up and down to drive the roller 96 and the inner wall of the slide 811 to cause rotation. When the eccentric wheel 97 rotates with the rotating shaft 95, it will repeatedly squeeze the air bag 99. The other end of the air pressure chamber 98 is slidably connected to the internal piston of the push rod 910. The end of the push rod 910 away from the air pressure chamber 98 is connected to the closed ring 911. The top of the oil injection pipe 91 is fixedly connected, a one-way component 912 is arranged on the top of the oil injection pipe 91, and the one-way component 912 includes a fixed frame 9121 and a rotating rod 9122. The fixed frame 9121 is fixedly connected to the oil injection pipe 91, and torsion springs 9123 are arranged at both ends of the rotating rod 9122. The rotating rod 9122 penetrates and is rotatably connected to the fixed frame 9121 through the torsion springs 9123 at both ends. The surface of the rotating rod 9122 is fixedly connected with a closing plate 9124, and the closing plate 9124 will deflect upward when impacted. The smoothing mechanism 10 includes a connecting frame 101 and a long rod 107. The bottom of the connecting frame 101 is fixedly connected to the top of the slider 812, and the inner side of the connecting frame 101 is rotatably connected with a cross bar 102, and the surface of the cross bar 102 is fixedly connected with a pulley 103 and a bevel gear A 104, the number of pulleys 103 is set to two groups, and the outer walls of the two groups of pulleys 103 are in close contact with the inner wall of the slide 811. When the two groups of pulleys 103 rotate by friction with the inner wall of the slide 811, the cross bar 102 will rotate. The inner bottom of the connecting frame 101 is rotatably connected with a vertical rod 105, and a transmission belt 109 is set on the surface of the vertical rod 105. The top of the vertical rod 105 is fixedly connected with a bevel gear B106. The bottom of the long rod 107 is rotatably connected with the top of the slider 812, and a smoothing ring 108 is fixedly connected on the surface of the long rod 107. The bevel gear A104 is vertically meshed with the bevel gear B106. The long rod 107 is connected to the vertical rod 105 through the transmission belt 109. The rotation of the bevel gear A104 will drive the bevel gear B106 to rotate.When the vertical rod 105 rotates, the long rod 107 is driven to rotate through the transmission belt 109.

[0024] When in use, lubricating oil is injected into the oil storage chamber 92 through the oil filling pipe 91, and the closing plate 9124 will be deflected upward by the impact force. After the oil filling is completed, the torsion spring 9123 rebounds and drives the rotating rod 9122 and the closing plate 9124 to reverse and restore to re-close the oil filling pipe 91 to prevent the lubricating oil from flowing back. When the inner wall of the slide cylinder 811 becomes rough after long-term use, the friction force of the inner wall of the slide cylinder 811 becomes larger. At this time, the slider 812 slides up and down, driving the roller 96 and the inner wall of the slide cylinder 811 to rotate. When the eccentric wheel 97 rotates with the rotating shaft 95, it will repeatedly squeeze the airbag 99. The air pressure in the airbag 99 will enter the air pressure chamber 98 to push the push rod 910 to move downward. The downward movement of the push rod 910 will drive the closing ring 911 to move downward. When the eccentric wheel 97 leaves the airbag 99, the airbag 99 rebounds and the air pressure returns to the airbag 99. At this time, the push rod 910 moves upward and drives the closing ring 911 upward When the movement is restored, the closed ring 911 moves downward intermittently to open the oil leakage hole 93. When the oil leakage hole 93 is opened, the lubricating oil will flow out through the oil leakage hole 93 to the inner wall of the slide 811 for lubrication. Then, when the friction becomes smaller and the roller 96 no longer rotates, the oil leakage hole 93 is in a closed state and the lubricating oil no longer flows out. When the friction force of the inner wall of the slide 811 is large, the slider 812 will also drive the two sets of pulleys 103 to rotate with the friction of the inner wall of the slide 811 when moving up and down, so that the cross bar 102 rotates. The rotation of the cross bar 102 will drive the bevel gear A104 to rotate. The rotation of the bevel gear A104 will drive the bevel gear B106 to rotate. When the vertical rod 105 rotates, it will drive the long rod 107 to rotate through the transmission belt 109. The rotation of the long rod 107 will drive the smearing ring 108 to rotate. The rotation of the smearing ring 108 can evenly spread the leaked lubricating oil on the inner wall of the slide 811 to improve the lubrication effect.
