[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] Reference Figure 1-Figure 5 A shock absorber for a new energy vehicle includes a first fixing plate 6 and a second fixing plate 8. A first shock absorbing assembly 1 is installed at both ends of the first fixing plate 6, and a second shock absorbing assembly 4 is installed at both ends of the second fixing plate 8. The first shock absorbing assembly 1 is connected to the second shock absorbing assembly 4. The first shock absorbing assembly 1 includes a sleeve 103. A dust cover 201 is slidably connected to the outer side of the sleeve 103. A support plate 102 is fixed to the top of the dust cover 201 by bolts, and the support plate 102 is rotatably connected to the first fixing plate 6. A return spring 101 is welded to the bottom of the support plate 102, and the bottom end of the return spring 101 is fixed to the sleeve 103. A connecting rod 104 is movably inserted in the sleeve 103, and the top end of the connecting rod 104 is fixed to the support plate 102. The interior of the sleeve 103 is slidably connected to the first piston 105, and the bottom end of the connecting rod 104 extends into the interior of the sleeve 103 and is slidably connected to the sleeve 103. When the first fixed plate 6 and the second fixed plate 8 are subjected to external force, the first shock absorbing assembly 1 and the second shock absorbing assembly 4 start to work. In the first shock absorbing assembly 1, the external force is first transmitted to the connecting rod 104 through the support plate 102, and the connecting rod 104 drives the first piston 105 to slide in the sleeve 103. During this process, the return spring 101 absorbs part of the energy.

[0035] In particular, two check assemblies 5 are installed on the connecting rod 104, and the two check assemblies 5 are respectively located at the top and bottom of the first piston 105. The check assembly 5 includes a limit ring 107, which is welded to the outside of the connecting rod 104. A connecting plate 501 is welded to one side of the limit ring 107, and a protrusion 502 is welded to the bottom of the connecting plate 501. Two through holes 106 are provided inside the first piston 105, and the protrusion 502 can block the two ends of the through holes 106 at adjacent positions. The sliding of the connecting rod 104 can drive the protrusion 502 in the check assembly 5 to move, so that the protrusion 502 can block the two ends of the through hole 106 of the first piston 105. The sealing is performed to control the flow direction of the gas. When the connecting rod 104 moves downward, the top protrusion 502 blocks the top of the adjacent through hole 106, and the bottom protrusion 502 moves downward at the same time. At this time, there is a gap between the bottom protrusion 502 and the bottom of the adjacent through hole 106, so that the oil at the bottom of the first piston 105 flows upward through this through hole 106. When the connecting rod 104 moves upward, the protrusion 502 at the bottom blocks the bottom of the adjacent through hole 106, and the protrusion 502 at the top moves out of the top of the adjacent through hole 106, thereby ensuring the unidirectional flow of gas and enhancing the shock absorption effect.

[0036] It should be noted that the outer portions of the first piston 105 located at the plurality of through holes 106 are all bonded with sealing rings 503, and the sealing rings 503 are in contact with the protrusions 502 at the corresponding positions. The sealing rings 503 make the protrusions 502 and the openings of the through holes 106 more tightly connected. The second shock absorbing assembly 4 includes a second piston block 401, which is slidably connected to the interior of the sleeve 103. A shell 403 is welded to the outer side of the bottom end of the sleeve 103. A plurality of connecting holes 402 are opened at the bottom of the sleeve 103, and The connecting hole 402 is connected to the shell 403. In the second shock absorber assembly 4, the first piston 105 moves downward to make the second piston block 401 slide in the sleeve 103, and cooperate with the connecting hole 402 to further absorb and disperse energy. That is, in the process of the second piston block 401 moving downward, the nitrogen at the bottom of the second piston block 401 in the sleeve 103 and the nitrogen in the shell 403 are compressed. Through the unidirectional flow of oil, the gas in the closed air chamber is compressed or expanded, and the impact energy is absorbed by the compressibility of the gas.

[0037] In the present invention, a heat dissipation component 3 is provided at the bottom of the sleeve 103, and the heat dissipation component 3 includes a plurality of slots 305, and the plurality of slots 305 are all opened at the bottom of the sleeve 103. Heat conducting plates 303 are fixed in the plurality of slots 305 by bolts, and heat conducting rings 304 are welded between the plurality of heat conducting plates 303. A plurality of heat dissipation plates 302 are fixed to the outside of the heat conducting rings 304 by bolts, and a plurality of slots 301 are opened on the plurality of heat dissipation plates 302. The first piston 105 contacts the heat conducting plate 303, and the first piston 105 slides and contacts the heat conducting plate 303. The heat conducting plate 303 transfers heat to the plurality of heat dissipation plates 302 through the heat conducting ring 304. The slots 301 on the heat dissipation plates 302 help to dissipate heat, thereby realizing the heat dissipation function.

[0038] A bellows 202 is fixed between the top outer wall of the sleeve 103 and the bottom of the support plate 102 by bolts, and the bellows 202 covers the top part of the connecting rod 104 extending out of the sleeve 103. The bellows 202 is located in the internal cavity of the return spring 101. The coordinated use of the dust cover 201 and the bellows 202 helps to protect the connecting rod 104 and the return spring 101 from dust and impurities, thereby extending the service life of the device. A mounting head 7 is welded to the top of the first fixing plate 6 and the bottom of the second fixing plate 8. The mounting head 7 is provided with a mounting hole, which facilitates the connection and fixation of the device to the vehicle body and the axle. The second piston block 401 is located above the connecting hole 402. The space in the sleeve 103 located at the top of the first piston 105 and the space in the sleeve 103 located between the first piston 105 and the second piston block 401 both contain oil. The space in the sleeve 103 located at the bottom of the second piston block 401 and the housing 403 contain nitrogen.

[0039] Working principle: When the first fixing plate 6 and the second fixing plate 8 are subjected to an external force, the first shock absorbing assembly 1 and the second shock absorbing assembly 4 start to work. In the first shock absorbing assembly 1, the external force is first transmitted to the connecting rod 104 through the support plate 102. The connecting rod 104 drives the first piston 105 to slide in the sleeve 103. During this process, the return spring 101 absorbs part of the energy.

[0040] The sliding of the connecting rod 104 can drive the protrusion 502 in the anti-return assembly 5 to move, so that the protrusion 502 can block the two ends of the through hole 106 of the first piston 105, thereby controlling the flow direction of the gas. When the connecting rod 104 moves downward, the top protrusion 502 blocks the top of the through hole 106 adjacent to it, and the bottom protrusion 502 moves downward at the same time. At this time, there is a gap between the bottom protrusion 502 and the bottom of the through hole 106 adjacent to it, so that the oil at the bottom of the first piston 105 flows upward through this through hole 106. When the connecting rod 104 moves upward, the protrusion 502 at the bottom blocks the bottom of the through hole 106 adjacent to it, and the protrusion 502 at the top moves out of the top of the through hole 106 adjacent to it, thereby ensuring the unidirectional flow of gas and enhancing the shock absorption effect.

[0041] At the same time, the first piston 105 slides and contacts the heat conducting plate 303, which transfers heat to the plurality of heat dissipating plates 302 through the heat conducting ring 304. The slots 301 on the heat dissipating plates 302 help to dissipate the heat, thereby achieving the heat dissipation function.

[0042] In the second shock-absorbing assembly 4, the first piston 105 moves downward to cause the second piston block 401 to slide in the sleeve 103, and cooperate with the connecting hole 402 to further absorb and disperse energy. That is, during the downward movement of the second piston block 401, the nitrogen at the bottom of the second piston block 401 in the sleeve 103 and the nitrogen in the shell 403 are compressed. When the external force disappears, the return spring 101 pushes the support plate 102 and the connecting rod 104 to return to their original state, and the first piston 105 and the second piston block 401 are also returned to their original state, and the device returns to its initial state.
