[0035] The heat insulating member 40 is disposed around the muffler 20 , and the heat insulating member 40 includes a first heat insulating portion 41 and a second heat insulating portion 42 .

[0037] The muffler 20 is a part of the exhaust system. The high-temperature exhaust gas is discharged to the outside of the vehicle 100 through the muffler 20. The temperature of the muffler 20 is relatively high. The first heat insulating portion 41 is located between the muffler 20 and the vehicle body. The first heat insulating portion 41 blocks the heat on the muffler 20 from being transferred to the vehicle body. The second heat insulating portion 42 is located between the muffler 20 and the second cross beam 12 of the frame 10. The first heat insulating portion 41 blocks the heat on the muffler 20 from being transferred to the frame 10.

[0038] It should be noted that the vehicle frame 10 further includes a longitudinal beam, and the first cross beam 11 and the second cross beam 12 are respectively mounted on the longitudinal beam. The arrangement of the longitudinal beam and the cross beam is prior art and will not be described in detail here.

[0039] In the related art, the body and frame of a non-load-bearing vehicle are in relative motion. In order to provide sufficient heat insulation, multiple heat insulation covers are provided around the muffler, and the number of parts is relatively large.

[0040] Specifically, in the related art, a body heat shield is installed at the bottom of the body, and a frame heat shield is installed on the frame, and they need to be installed separately, resulting in a large number of parts and components and high costs.

[0041] In the embodiment of the utility model, a first connecting portion 411 and a second connecting portion 421 are provided on the heat insulating member 40. The first connecting portion 411 is connected to the first cross beam 11 of the frame 10, and the second connecting portion 421 is connected to the second cross beam 12 of the frame 10. The heat insulating member 40 is integrally mounted on the frame 10. The heat insulating member 40 is constructed as an integral part, thereby reducing the number of components and reducing costs.

[0042] Among them, the heat insulation member 40 is an integrated member, the heat insulation member 40 extends from front to rear, and the heat insulation member 40 extends from the first cross beam 11 to the direction of the second cross beam 12. The heat insulation member 40 insulates the heat of the muffler 20 in a surrounding manner, thereby preventing the heat of the muffler 20 from being transferred to surrounding components, thereby improving the durability of surrounding components.

[0043] According to the vehicle 100 of the embodiment of the utility model, the heat insulation 40 is integrally installed on the frame 10, and the heat insulation 40 is constructed as an integral part. The heat insulation 40 has a first heat insulation part 41 and a second heat insulation part 42. The heat insulation 40 surrounds the muffler 20 to prevent the heat of the muffler 20 from being transferred to the surrounding components, thereby improving the durability of the surrounding components, reducing the number of components, improving the integration, and reducing costs.

[0044] Reference Figure 2 In some embodiments, a bumper assembly is provided on the vehicle frame 10, and the heat insulation member 40 further includes: a third heat insulation portion 43, one end of the third heat insulation portion 43 is connected to the first heat insulation portion 41, and the other end of the third heat insulation portion 43 is connected to the second heat insulation portion 42, and the third heat insulation portion 43 is provided between the bumper assembly and the muffler 20.

[0045] The third heat insulating portion 43 is disposed between the first heat insulating portion 41 and the second heat insulating portion 42 , and the first heat insulating portion 41 , the second heat insulating portion 42 and the third heat insulating portion 43 are integrally formed.

[0046] In the above scheme, by arranging the third heat insulating part 43 between the bumper assembly and the muffler 20, the third heat insulating part 43 blocks the heat of the muffler 20 from being transferred to the bumper assembly, thereby improving the thermal impact of the muffler 20 on the bumper assembly and improving the durability of the bumper assembly.

[0047] Specifically, the bumper assembly is mounted on the second cross beam 12 , the bumper assembly extends obliquely forward, and the third heat insulating portion 43 is located between the bumper assembly and the muffler 20 to isolate heat.

[0048] Reference Figure 2 In some embodiments, the third heat insulating portion 43 is at least partially constructed as a curved plate 431, and the curved plate 431 has a concave surface, which faces the muffler 20 to guide the air to flow downward.

[0049] It can be understood that the arc plate 431 is bent in one direction, and one side of the arc plate 431 facing the bending direction is a concave surface, and the other side of the arc plate 431 opposite to the curved surface is a corresponding convex surface.

[0050] In the above scheme, by at least partially constructing the third heat insulation part 43 as an arc plate 431 and using the shape of the arc plate 431 to guide the flow of air, during the movement of the vehicle 100, the heat of the muffler 20 is avoided to the surrounding parts, such as the bumper assembly, to the greatest extent possible, thereby effectively improving the thermal impact of the muffler 20 on the surrounding parts, thereby improving the durability of the surrounding parts.

[0051] Specifically, the third heat insulating portion 43 may be configured as a curved plate 431 in its entirety or partially as a curved plate 431 .

[0052] Reference Figure 3 In some embodiments, a first reinforcing rib 44 and a second reinforcing rib 45 are provided on the thermal insulation member 40, a portion of the first reinforcing rib 44 is provided on the first thermal insulation portion 41, and the remaining portion of the first reinforcing rib 44 is provided on the third thermal insulation portion 43, and the second reinforcing rib 45 and the first reinforcing rib 44 have an intersection point 441, and the intersection point 441 is located in the third thermal insulation portion 43.

[0053] The first reinforcing rib 44 extends from the first heat insulating portion 41 to the third heat insulating portion 43 , the second reinforcing rib 45 is arranged to intersect with the first reinforcing rib 44 , and the first reinforcing rib 44 and the second reinforcing rib 45 intersect at an intersection 441 .

[0054] In the above scheme, by setting the first reinforcing rib 44 and the second reinforcing rib 45 to intersect, the first reinforcing rib 44 and the second reinforcing rib 45 cooperate to further improve the strength of the insulation component 40, and the intersection point 441 is set at the third insulation part 43 to specifically enhance the strength of the third insulation part 43.

[0055] For example, the first reinforcing rib 44 extends in the front-to-back direction, the first reinforcing rib 44 extends from the first insulation part 41 to the third insulation part 43 , the second reinforcing rib 45 extends to the third insulation part 43 , and the first reinforcing rib 44 and the second reinforcing rib 45 intersect at the third insulation part 43 .

[0056] Reference Figure 1 , Figure 3 In some embodiments, the first reinforcing rib 44 extends in the front-to-back direction, the second reinforcing rib 45 extends in the left-to-right direction, and the second reinforcing rib 45 is disposed in the third heat insulating portion 43 .

[0057] Among them, the front-to-back direction is the longitudinal direction of the vehicle 100, the left-to-right direction is the transverse direction of the vehicle 100, the first reinforcing rib 44 extends along the longitudinal direction of the vehicle 100, the second reinforcing rib 45 is located as a whole on the third heat insulation part 43, the second reinforcing rib 45 extends along the transverse direction of the vehicle 100, and the first reinforcing rib 44 and the second reinforcing rib 45 intersect at the third heat insulation part 43.

[0058] In the above scheme, by providing a first reinforcing rib 44 extending in the front-to-back direction and a second reinforcing rib 45 extending in the left-to-right direction, the first reinforcing rib 44 extending in the front-to-back direction and the second reinforcing rib 45 extending in the left-to-right direction can be converged on the third insulation part 43, so that the insulation component 40 can be strengthened in both the transverse and longitudinal directions, thereby improving the overall strength.

[0059] Reference Figure 3 In some embodiments, there are multiple first reinforcing ribs 44 , and the multiple first reinforcing ribs 44 are arranged at intervals along the left-right direction. In the left-right direction, the first connecting portion 411 corresponds to the space between two adjacent first reinforcing ribs 44 .

[0060] Among them, multiple first reinforcing ribs 44 are arranged at intervals along the left-right direction, and the space between two adjacent first reinforcing ribs 44 corresponds to the first connecting portion 411. Taking the entire thermal insulation component 40 as the observation object, the first connecting portion 411 is located between two adjacent first reinforcing ribs 44.

[0061] In the above scheme, by setting the first connection part 411 corresponding to the space between two adjacent first reinforcing ribs 44 and coordinating the arrangement of the first connection part 411 and the first reinforcing ribs 44, the force transmitted by the first connection part 411 can be better dispersed to the first reinforcing ribs 44, thereby improving the overall force-bearing capacity of the insulation room.

[0062] In some embodiments, the heat insulating member 40 is configured to be stationary relative to the frame 10, and the muffler 20 is connected to the frame 10 via a flexible member. The minimum distance between the heat insulating member 40 and the muffler 20 is greater than or equal to 30 mm.

[0063] The heat insulating member 40 is fixedly connected to the vehicle frame 10 , and the heat insulating member 40 is fixed to the vehicle frame 10 , while the muffler 20 is connected to the vehicle frame 10 via a flexible member, such as a rubber suspension, and the muffler 20 has a certain degree of mobility.

[0064] In the above scheme, the muffler 20 is connected to the frame 10 through a flexible member. The flexible member effectively absorbs the vibration of the muffler 20, prevents the vibration from being transmitted to the passenger compartment, and improves riding comfort. At the same time, the flexible member can avoid structural stress caused by thermal expansion and contraction in the connecting parts between the muffler 20 and the frame 10, thereby avoiding damage. The minimum distance between the heat insulating member 40 and the muffler 20 is set to be greater than or equal to 30 mm, and the distance between the muffler 20 and the heat insulating member 40 is maintained to avoid collision between the two.

[0065] In some embodiments, the first connection portion 411 is configured as a first connection hole, a first connection member is disposed in the first connection hole, and the first connection member is connected to the first beam 11, and the second connection portion 421 is configured as a second connection hole, a second connection member is disposed in the second connection hole, and the second connection member is connected to the second beam 12. There are multiple first connection members and multiple second connection members, and in the left-right direction, the multiple first connection members and the multiple second connection members are staggered.

[0066] Among them, the staggered arrangement means that adjacent elements are arranged in an alternating manner, taking the entire insulation member 40 as the observation object, and multiple first connectors and second connectors are arranged alternately, for example, the arrangement of first connector-second connector-first connector, or the arrangement of second connector-first connector-second connector.

[0067] In the above solution, by staggeredly arranging a plurality of first connecting members and a plurality of second connecting members, the force on the heat insulating member 40 is more evenly distributed, thereby increasing the stability of the heat insulating member 40.

[0068] Specifically, the first connection hole may be a plain hole or a threaded hole, the first connection member in the first connection hole may be a screw or a bolt, the first connection member is connected to the first beam 11, and the first heat insulating portion 41 is fixed to the first beam 11. The second connection hole may be a plain hole or a threaded hole, the second connection member in the second connection hole may be a screw or a bolt, the second connection member is connected to the second beam 12, and the second heat insulating portion 42 is fixed to the second beam 12.

[0071] In the above scheme, the first connecting hole is opened on the first raised portion 412, and the strength of the portion where the first connecting hole is installed on the first insulation portion 41 is enhanced by utilizing the raised structure of the first raised portion 412, thereby reducing the probability of damage to the insulation member 40. The second connecting hole is opened on the second raised portion 422, and the strength of the portion where the second connecting hole is installed on the second insulation portion 42 is enhanced by utilizing the raised structure of the second raised portion 422, thereby reducing the probability of damage to the insulation member 40.

The first heat insulating portion 41 includes a heat insulating body 413 and an avoidance portion 414, the avoidance portion 414 is provided at one end of the heat insulating body 413 in the left-right direction, the avoidance portion 414 is closer to the muffler 20 than the heat insulating body 413, and at least part of the connecting harness 50 is correspondingly provided above the avoidance portion 414.

[0073] Among them, the connecting harness 50 connects the control component and the electrical component, and the connecting harness 50 plays a connecting role to transmit signals or energy. The avoidance portion 414 is closer to the muffler 20 than the heat insulation body 413, and the distance between the avoidance portion 414 and the muffler 20 is smaller than the distance between the heat insulation body 413 and the muffler 20.

[0074] In the above scheme, the avoidance portion 414 is provided to avoid the connecting harness 50, and the heat insulation member 40 isolates the connecting harness 50 from the muffler 20, thereby preventing the connecting harness 50 from being affected by the muffler 20, so that the connecting harness 50 is in a better working environment and the safety is improved.

[0075] Specifically, the first heat insulating portion 41 is located above the muffler 20 , and the height of the heat insulating body 413 is higher than the height of the avoidance portion 414 .
