Technical Field

[0001] This application relates to the field of vehicle heat insulation components, specifically to a heat insulation structure and a vehicle. Background Technology

[0002] Currently, vehicle engines generate a significant amount of heat during operation, some of which dissipates into the engine compartment through the exhaust system. The engine compartment contains numerous pipes and components, and the heat dissipated through the exhaust system can affect the lifespan and normal operation of these pipes and components. However, due to the complex installation of pipes and components within the engine compartment, installing heat insulation structures is quite difficult. Therefore, how to utilize the space inside the engine compartment to isolate the heat radiated by the exhaust system from the pipes and components, and how to quickly dissipate the heat to the outside of the vehicle, is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0003] In view of the above, it is necessary to propose a heat insulation structure and vehicle to make reasonable use of the space inside the engine compartment, isolate the heat radiated by the exhaust system from the pipes and components, and allow the heat to circulate quickly to the outside of the vehicle.

[0004] This application provides a heat insulation structure applied to a vehicle. The heat insulation structure has a flow channel for the vehicle's exhaust system to pass through. The heat insulation structure includes a first heat insulation cover and a second heat insulation cover. The first heat insulation cover is used to connect to the vehicle's subframe and / or steering system to isolate the exhaust system from the vehicle's piping. The second heat insulation cover is used to connect to the steering system to isolate the exhaust system from the steering system. A first space is provided between the first heat insulation cover and the second heat insulation cover, and the flow channel includes the first space.

[0005] In some embodiments, the first heat shield includes a cover body and a snap-fit ​​element. The cover body is used to connect to the subframe and / or the steering system. The first space is located between the cover body and the second heat shield. The snap-fit ​​element is disposed on the side of the cover body opposite to the second heat shield and is used to snap-fit ​​the pipeline.

[0006] In some embodiments, the first heat shield further includes a first bracket, one end of which is connected to the shield body and the other end of which is connected to the subframe; and / or, the first heat shield further includes a second bracket, one end of which is connected to the steering system and the other end of which is connected to the shield body.

[0007] In some embodiments, the heat insulation structure further includes a third heat insulation cover disposed between the first heat insulation cover and the second heat insulation cover. The third heat insulation cover, together with the first heat insulation cover and the second heat insulation cover, encloses the first space. The third heat insulation cover is used to connect to the catalytic converter and the exhaust pipe of the exhaust system to isolate the pipeline from the catalytic converter and the exhaust pipe.

[0008] In some embodiments, the portion of the third heat shield near the first heat shield is vertically spaced from the portion of the first heat shield near the third heat shield.

[0009] In some embodiments, the heat insulation structure further includes a fourth heat insulation cover, which is disposed on one side of the first heat insulation cover. One end of the fourth heat insulation cover extends toward the first heat insulation cover, and the other end of the fourth heat insulation cover extends along the extension direction of the exhaust system. The fourth heat insulation cover is used to connect with the energy absorption box of the vehicle. There is a second space between the fourth heat insulation cover and the second heat insulation cover that communicates with the first space. The flow channel further includes the second space.

[0010] In some embodiments, the portion of the fourth heat shield near the first heat shield is vertically spaced from the portion of the first heat shield near the fourth heat shield.

[0011] In some embodiments, the heat insulation structure further includes a fifth heat insulation cover disposed on the side of the fourth heat insulation cover away from the first heat insulation cover, the fifth heat insulation cover being disposed along the extension direction of the exhaust system, and the fifth heat insulation cover being located below the driver's compartment of the vehicle.

[0012] In some embodiments, the heat insulation structure further includes a sixth heat insulation cover disposed on the side of the first heat insulation cover away from the second heat insulation cover, the sixth heat insulation cover being used to connect to the battery pack of the vehicle to isolate the exhaust system from the battery pack.

[0013] In some embodiments, the sixth heat insulation cover is provided with a drainage hole; and / or, the portion of the sixth heat insulation cover near the first heat insulation cover is vertically spaced from the portion of the first heat insulation cover near the sixth heat insulation cover.

[0014] The heat insulation structure of this application embodiment connects a first heat insulation cover to the vehicle's subframe and / or steering system, and a second heat insulation cover to the steering system. This makes efficient use of the space inside the engine compartment and isolates the heat radiated by the exhaust system from the pipes and steering system components, preventing the heat radiated by the exhaust system from affecting these components. The heat insulation structure also includes a flow channel for the vehicle's exhaust system, allowing air to quickly dissipate the heat radiated by the exhaust system to the outside of the vehicle. Furthermore, by connecting a third, fourth, fifth, and sixth heat insulation cover to corresponding components inside the engine compartment and isolating the exhaust system from these components, the space inside the engine compartment is made efficient, and the heat radiated by the exhaust system is prevented from affecting the corresponding components.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0029] The following will describe some embodiments of this application in detail with reference to the accompanying drawings.

[0030] Please see Figure 1 and Figure 4This application provides a heat insulation structure 100 applied to a vehicle 1000, wherein the vehicle 1000 can be a fuel vehicle, a hybrid vehicle, etc. For ease of understanding, this application uses a hybrid vehicle as an example for illustration. Obviously, this is not a limitation of this application.

[0031] Please see Figure 1 , Figure 4 and Figure 5 In this embodiment, the heat insulation structure 100 has a flow channel 70 for the exhaust system 810 of the vehicle 1000 to pass through. The heat insulation structure 100 includes a first heat insulation cover 10 and a second heat insulation cover 20. The first heat insulation cover 10 is used to connect to the subframe 820 and / or steering system 830 of the vehicle 1000 to isolate the exhaust system 810 from the pipeline 840 of the vehicle 1000. The second heat insulation cover 20 is used to connect to the steering system 830 to isolate the exhaust system 810 from the steering system 830. A first space 71 is provided between the first heat insulation cover 10 and the second heat insulation cover 20. The flow channel 70 includes the first space 71.

[0032] Specifically, the first heat shield 10 and the second heat shield 20 are both installed in the engine compartment (not shown). The first heat shield 10 is connected to the subframe 820 and the steering tube beam 8301 of the steering system 830, respectively. The pipe 840 passes through the side of the first heat shield 10 away from the second heat shield 20. The first heat shield 10 prevents the heat radiated by the exhaust system 810 from affecting the pipe 840. The second heat shield 20 is fixed to the steering system 830 to prevent the heat radiated by the exhaust system 810 from affecting the steering motor (not shown) and the active stabilizer bar 8302 of the steering system 830.

[0033] The heat insulation structure 100 of this application embodiment connects to the subframe 820 and / or steering system 830 of the vehicle 1000 by setting a first heat insulation cover 10, and a second heat insulation cover 20 connects to the steering system 830. This makes efficient use of the space inside the engine compartment and isolates the heat radiated by the exhaust system 810 from the components of the pipes 840 and steering system 830, preventing the heat radiated by the exhaust system 810 from affecting the components of the pipes 840 and steering system 830. By providing a flow channel 70 for the exhaust system 810 of the vehicle 1000 to pass through, and including a first space 71 between the first heat insulation cover 10 and the second heat insulation cover 20, the heat radiated by the exhaust system 810 is quickly circulated to the outside of the vehicle by air through the flow channel 70.

[0034] Please refer to the following: Figure 2In this embodiment, the first heat shield 10 includes a shield body 11 and a snap-fit ​​member 12. The shield body 11 is used to connect to the subframe 820 and / or the steering system 830. The first space 71 is located between the shield body 11 and the second heat shield 20. The snap-fit ​​member 12 is located on the side of the shield body 11 opposite to the second heat shield 20 and is used to snap-fit ​​with the pipe 840. This facilitates the connection or disconnection of the pipe 840 from the first heat shield 10, thereby facilitating after-sales maintenance.

[0035] In this embodiment, the pipeline 840 may include a water pipe 8401 and a high-voltage wiring harness 8402. The water pipe 8401 is snapped into the clamp 12, and the high-voltage wiring harness 8402 is connected to the cover 11 by a double-ended bolt (not shown). During installation, the nut is tightened from the top (not shown), and during disassembly, the nut is loosened from the bottom, which facilitates the connection or separation of the first heat insulation cover 10 and the high-voltage wiring harness 8402, and facilitates after-sales maintenance.

[0036] In this embodiment, the cover 11 can be an aluminized steel plate structure. The cover 11 has a connection hole (not shown in the figure) and a screw connector 15 is provided on the cover 11. The connection hole and the screw connector 15 are reserved connection structures to facilitate connection with other components.

[0037] Please refer to the following: Figure 7 The first heat shield 10 also includes a first bracket 13 and a second bracket 14. One end of the first bracket 13 is connected to the shield body 11, and the other end is connected to the subframe 820. Specifically, the first bracket 13 can be bolted to the shield body 11 and the subframe 820 respectively. One end of the second bracket 14 is connected to the steering tube beam 8301 of the steering system 830, and the other end is connected to the shield body 11. Specifically, the second bracket 14 can be bolted to the shield body 11 and the steering tube beam 8301 respectively. If the steering system 830 malfunctions or other situations require the subframe 820 to be disassembled, after-sales personnel only need to remove the corresponding bolts from the underside of the chassis (not shown in the figure), and the first heat shield 10 will be detached from the chassis parts, avoiding the need to disassemble the pipes 840 along with the subframe 820, thus reducing disassembly time and additional disassembly costs. The bolts connecting the second bracket 14 and the steering tube beam 8301 are located between the steering tube beam 8301 and the active stabilizer bar 8302, and the lower part of the subframe 820 is provided with an opening (not shown) to facilitate the after-sales personnel to lift the vehicle 1000 and remove the first heat shield 10 from the bottom.

[0038] In some other embodiments, the first heat shield 10 further includes either the first bracket 13 or the second bracket 14, that is, the first heat shield 10 includes either the first bracket 13 or the second bracket 14. Correspondingly, one end of the first bracket 13 is connected to the cover 11, and the other end of the first bracket 13 is connected to the subframe 820; or, one end of the second bracket 14 is connected to the steering tube beam 8301 of the steering system 830, and the other end of the second bracket 14 is connected to the cover 11. This application does not specifically limit this aspect.

[0039] Please refer to the following: Figure 6 and Figure 7 In this embodiment, the second heat shield 20 is an embossed aluminum plate structure. The second heat shield 20 is fixed to the steering tube beam 8301 by bolts. A third bracket 21 is provided on the side of the second heat shield 20 facing the first heat shield 10. The third bracket 21 is connected to the bolts connecting the second heat shield 20 and the steering tube beam 8301. The second bracket 14 is connected to the third bracket 21 by bolts, thereby forming a connection relationship between the second bracket 14 and the steering tube beam 8301. The second heat shield 20 is provided with a clearance hole 22 that is directly opposite to the connection point of the second bracket 14 and the third bracket 21, so that the second bracket 14 and the third bracket 21 can be separated from the vehicle 1000 from below by using a screwdriver or other tools through the clearance hole 22.

[0040] Please refer to it again. Figure 1 , Figure 4 and Figure 5 In this embodiment, the heat insulation structure 100 further includes a third heat insulation cover 30, which is disposed between the first heat insulation cover 10 and the second heat insulation cover 20. The third heat insulation cover 30, together with the first heat insulation cover 10 and the second heat insulation cover 20, encloses the first space 71. The third heat insulation cover 30 is used to connect with the catalyst 8101 and the exhaust pipe 8102 of the exhaust system 810 to separate the pipeline 840 from the catalyst 8101 and the exhaust pipe 8102.

[0041] Specifically, the third heat shield 30 can be an embossed aluminum plate structure, and a portion of the pipe 840 passes through the side of the third heat shield 30 opposite to the first space 71. Since the catalytic converter 8101 and exhaust pipe 8102 of the exhaust system 810 are the main sources of heat radiation, by connecting the third heat shield 30 to the catalytic converter 8101 and exhaust pipe 8102 of the exhaust system 810 and separating the pipe 840 from the catalytic converter 8101 and exhaust pipe 8102, the space in the engine compartment is utilized efficiently, and the impact of the heat radiated by the catalytic converter 8101 and exhaust pipe 8102 on the pipe 840 is effectively reduced. Furthermore, by setting the third heat shield 30 together with the first heat shield 10 and the second heat shield 20 to enclose the first space 71, the airtightness of the first space 71 is improved, thereby enhancing the heat dissipation effect of the flow channel 70.

[0042] In this embodiment, the portion of the third heat shield 30 near the first heat shield 10 and the portion of the first heat shield 10 near the third heat shield 30 are spaced vertically apart. Since the exhaust pipe 8102 vibrates when the vehicle 1000 is in motion, causing the third heat shield 30 to vibrate as well, this design helps avoid interference between the first heat shield 10 and the third heat shield 30. Furthermore, this design results in a smaller gap between the portion of the third heat shield 30 near the first heat shield 10 and the portion of the first heat shield 10 near the third heat shield 30, which helps reduce the amount of heat radiated by the catalytic converter 8101 and the exhaust pipe 8102 passing between the first heat shield 10 and the third heat shield 30.

[0043] Please refer to it again. Figure 1 , Figure 4 and Figure 5 In this embodiment, the heat insulation structure 100 further includes a fourth heat insulation cover 40, which may also be an embossed aluminum plate structure. The fourth heat insulation cover 40 is disposed on one side of the first heat insulation cover 10, with one end extending toward the first heat insulation cover 10 and the other end extending along the extension direction of the exhaust system 810. The fourth heat insulation cover 40 is used to connect with the energy absorption box 850 of the vehicle 1000. A second space 72 communicating with the first space 71 is provided between the fourth heat insulation cover 40 and the second heat insulation cover 20, and the flow channel 70 also includes the second space 72.

[0044] By connecting the fourth heat shield 40 to the energy-absorbing box 850, with one end of the fourth heat shield 40 extending towards the first heat shield 10 and the other end extending along the extension direction of the exhaust system 810, the space in the cabin is rationally utilized. This effectively conceals the gap above the energy-absorbing box 850 and the gap between the first heat shield 10 and the energy-absorbing box 850, reducing the impact of heat from the exhaust system 810 radiating from one side of the first heat shield 10 to the top of the first heat shield 10 on the pipeline 840. Furthermore, by establishing a second space 72 between the fourth heat shield 40 and the second heat shield 20, which communicates with the first space 71, and by including the second space 72 in the flow channel 70, the length of the flow channel 70 is increased, thereby further improving the heat dissipation effect of the flow channel 70.

[0045] In this embodiment, the portion of the fourth heat shield 40 near the first heat shield 10 and the portion of the first heat shield 10 near the fourth heat shield 40 are spaced vertically apart. Since the subframe 820 is flexibly connected to the vehicle body (not shown), there is relative movement between the subframe 820 and the vehicle body. Since the energy-absorbing box 850 is mounted on the vehicle body, the fourth heat shield 40 connected to the energy-absorbing box 850 will move relative to the first heat shield 10. This design helps to avoid interference between the fourth heat shield 40 and the first heat shield 10. Furthermore, this design results in a smaller gap between the portion of the fourth heat shield 40 near the first heat shield 10 and the portion of the first heat shield 10 near the fourth heat shield 40, which helps to reduce the amount of heat radiated by the exhaust system 810 passing between the first heat shield 10 and the fourth heat shield 40.

[0046] Please refer to it again. Figure 1 , Figure 4 and Figure 5 In this embodiment, the heat insulation structure 100 also includes a fifth heat insulation cover 50. The fifth heat insulation cover 50 is disposed on the side of the fourth heat insulation cover 40 away from the first heat insulation cover 10. The fifth heat insulation cover 50 is disposed along the extension direction of the exhaust system 810 and is located below the driver's cabin (not shown) of the vehicle 1000.

[0047] Specifically, the fifth heat shield 50 is an embossed aluminum plate structure, which is installed on the vehicle body and positioned along the extension direction of the exhaust pipe 8102. The fifth heat shield 50 separates the exhaust system 810 from the passenger compartment, effectively preventing heat from the exhaust system 810 from radiating into the passenger compartment and causing adverse experiences such as high temperatures at the driver's feet.

[0048] Please refer to it again. Figure 1 , Figure 4 and Figure 5 In this embodiment, the heat insulation structure 100 further includes a sixth heat insulation cover 60, which is disposed on the side of the first heat insulation cover 10 away from the second heat insulation cover 20. The sixth heat insulation cover 60 is used to connect to the battery assembly 860 of the vehicle 1000 to separate the exhaust system 810 from the battery assembly 860.

[0049] Specifically, the sixth heat shield 60 can be made of aluminized steel plate. By connecting the sixth heat shield 60 to the battery assembly 860 and separating the exhaust system 810 from the battery assembly 860, the space in the cabin is made reasonable use of the space and the heat radiated by the exhaust system 810 can be effectively reduced from affecting the battery assembly 860.

[0050] In this embodiment, the portion of the sixth heat shield 60 near the first heat shield 10 and the portion of the first heat shield 10 near the sixth heat shield 60 are vertically spaced. Since the subframe 820 moves the sixth heat shield 60 relative to the first heat shield 10 when the vehicle 1000 is in motion, this design helps avoid interference between the sixth heat shield 60 and the first heat shield 10. Furthermore, this design results in a smaller gap between the portion of the sixth heat shield 60 near the first heat shield 10 and the portion of the first heat shield 10 near the sixth heat shield 60, which helps reduce the amount of heat radiated by the exhaust system 810 passing between the first heat shield 10 and the sixth heat shield 60, and prevents the heat radiated by the exhaust system 810 from diffusing to the upper part of the sixth heat shield 60 and affecting the battery assembly 860.

[0051] Please refer to the following: Figure 3 In this embodiment, a drain hole 61 is provided on the sixth heat insulation cover 60. The drain hole 61 facilitates the smooth discharge of condensate generated by the air conditioner (not shown) to the outside of the vehicle.

[0052] In this embodiment, the sixth heat insulation cover 60 is located at the lower part of the pipeline 840. The high-voltage wiring harness 8402 of the pipeline 840 is fixed to the cable protection box (not shown). The cable protection box is connected to the sixth heat insulation cover 60 by bolts. The sixth heat insulation cover 60 can also protect the pipeline 840 and reduce the risk of the pipeline 840 being hit by water and rocks.

[0053] In summary, the heat insulation structure 100 of this application embodiment, by setting a first heat insulation cover 10 connected to the subframe 820 and / or steering system 830 of the vehicle 1000, and setting a second heat insulation cover 20 connected to the steering system 830, makes reasonable use of the space inside the engine compartment and isolates the heat radiated by the exhaust system 810 from the components of the pipes 840 and steering system 830, thus preventing the heat radiated by the exhaust system 810 from affecting the components of the pipes 840 and steering system 830. By setting the heat insulation structure 100 to have a flow channel 70 for the exhaust system 810 of the vehicle 1000 to pass through, the heat radiated by the exhaust system 810 can be quickly circulated to the outside of the vehicle through the flow channel 70. By setting a third heat insulation cover 30, a fourth heat insulation cover 40, a fifth heat insulation cover 50, and a sixth heat insulation cover 60 respectively connected to corresponding components inside the engine compartment and isolating the exhaust system 810 from the corresponding components, the space inside the engine compartment is made reasonable use of the space inside the engine compartment and prevents the heat radiated by the exhaust system 810 from affecting the corresponding components.

[0054] Please refer to it again. Figure 4 This application also provides a vehicle 1000, including the heat insulation structure 100 as described in the above embodiments.

[0055] The vehicle 1000 of this application embodiment, by setting the above-mentioned heat insulation structure 100, makes reasonable use of the space inside the engine compartment, separates the heat radiated by the exhaust system 810 from the pipes 840 and components, and facilitates the rapid flow of the heat radiated by the exhaust system 810 to the outside of the vehicle.
