Figure 1 Figure 2 As shown in FIGS. 1 and 2, in one embodiment, the heat shield 10 includes a shield body 1 and a baffle 2; the shield body 1 is provided with a receiving cavity 3 which penetrates through the shield body 1 along the front-back direction; the baffle 2 is connected to the shield body 1 and has a guide portion 2a opposite to the receiving cavity 3 in the front-back direction; the guide portion 2a is located at the front end of the shield body 1 and is inclined forward, and / or the guide portion 2a is located at the rear end of the shield body 1 and is inclined backward.

[0028] The guide portion 2a has a first end and a second end which are oppositely arranged, and the first end is connected to the shield body 1; when the guide portion 2a is located at the front end of the shield body 1, the distance between the guide portion 2a and the rear end of the shield body 1 gradually increases along the direction from the first end to the second end; when the guide portion 2a is located at the rear end of the shield body 1, the distance between the guide portion 2a and the front end of the shield body 1 gradually increases along the direction from the first end to the second end. Figure 1 Figure 2 As shown in FIGS. 1 and 2, in one embodiment, the heat shield 10 includes a shield body 1 and a baffle 2; the shield body 1 is provided with a receiving cavity 3 which penetrates through the shield body 1 along the front-back direction; the baffle 2 is connected to the shield body 1 and has a guide portion 2a opposite to the receiving cavity 3 in the front-back direction; the guide portion 2a is located at the front end of the shield body 1 and is inclined forward, and / or the guide portion 2a is located at the rear end of the shield body 1 and is inclined backward.

[0029] As shown in FIGS. 1 and 2, in one embodiment, the heat shield 10 includes a shield body 1 and a baffle 2; the shield body 1 is provided with a receiving cavity 3 which penetrates through the shield body 1 along the front-back direction; the baffle 2 is connected to the shield body 1 and has a guide portion 2a opposite to the receiving cavity 3 in the front-back direction; the guide portion 2a is located at the front end of the shield body 1 and is inclined forward, and / or the guide portion 2a is located at the rear end of the shield body 1 and is inclined backward. Figure 3 The heat shield 10 is used to connect the vehicle body of a vehicle so as to be arranged outside the exhaust pipe 20 of the vehicle; when the heat shield 10 is arranged outside the exhaust pipe 20, the exhaust pipe 20 penetrates through the receiving cavity 3.

[0030] It should be noted that the entire baffle 2 is the guide portion 2a, and in this case, the baffle 2 is the guide portion 2a, or the baffle 2 can be only a part of the guide portion 2a. Meanwhile, the guide portion 2a located at the front end of the shield body 1 means that the baffle 2 is located at the front end of the shield body 1, and the guide portion 2a located at the rear end of the shield body 1 means that the baffle 2 is located at the rear end of the shield body 1. Furthermore, one baffle 2 can mean one guide portion 2a, or one baffle 2 can mean multiple guide portions 2a, and in this case, when the baffle 2 is located at the front end of the shield body 1, each guide portion 2a of the baffle 2 is located at the front end of the shield body 1; when the baffle 2 is located at the rear end of the shield body 1, each guide portion 2a of the baffle 2 is located at the rear end of the shield body 1.

[0031] In addition, the guide portion 2a can be a flat plate, or the guide portion 2a can be a curved plate or the like.

[0032] ​​When the guide portion 2a is located at the front end of the cover body 1, the first end is connected to the front end of the cover body 1, and at this time, the distance between the guide portion 2a and the rear end of the cover body 1 gradually increases along the direction from the first end to the second end, which means that in this scenario, the distance between the front surface of the guide portion 2a and the rear end of the cover body 1 gradually increases along the direction from the first end to the second end, and at this time, the front surface of the guide portion 2a can be a plane or an arc surface. That is, the guide portion 2a is located at the front end of the cover body 1 and is inclined forward, which means that when the guide portion 2a is located at the front end of the cover body 1, the front surface of the guide portion 2a is inclined forward.

[0033] When the guide portion 2a is located at the rear end of the cover body 1, the first end is connected to the rear end of the cover body 1, and at this time, the distance between the guide portion 2a and the front end of the cover body 1 gradually increases along the direction from the first end to the second end, which means that in this scenario, the distance between the rear surface of the guide portion 2a and the rear end of the cover body 1 gradually increases along the direction from the first end to the second end, and at this time, the rear surface of the baffle 2 can be a plane or an arc surface. That is, the guide portion 2a is located at the rear end of the cover body 1 and is inclined backward, which means that when the guide portion 2a is located at the rear end of the cover body 1, the rear surface of the guide portion 2a is inclined backward.

[0034] In the prior art, the heat shield 10 usually only has the above-mentioned cover body 1, and in the forward driving of the vehicle, dry grass and the like are easy to enter the containing cavity 3 from the front end opening of the containing cavity 3 (i.e., enter the gap between the heat shield 10 and the exhaust pipe 20), and when the vehicle is driven backward (i.e., when reversing), dry grass and the like are easy to enter the containing cavity 3 from the rear end opening of the containing cavity 3. The front end opening of the containing cavity 3 is defined as the first opening, and the rear end opening of the containing cavity 3 is defined as the second opening, the first opening is the opening formed by the containing cavity 3 on the front end surface of the cover body 1, and the second opening is the opening formed by the containing cavity 3 on the rear end surface of the cover body 1.

[0035] In the present embodiment, however, the baffle 2 is provided on the basis of the existing heat shield, and the guide portion 2a of the baffle 2 is inclined to the outside of the containing cavity 3. When the guide portion 2a is located at the front end of the cover body 1, the second end of the guide portion 2a is located in front of the first end, and if the combustible material such as dry grass on the ground moves from the front of the heat shield 10 to the rear relative to the vehicle, the guide portion 2a can guide the combustible material to move to the side away from the containing cavity 3 of the guide portion 2a, so as to avoid entering the containing cavity 3, and further avoid entering the gap between the cover body 1 and the exhaust pipe 20. When the guide portion 2a is located at the rear end of the cover body 1, the second end of the guide portion 2a is located behind the first end, and if the combustible material such as dry grass on the ground moves from the rear of the heat shield 10 to the front relative to the vehicle, the guide portion 2a can guide the combustible material to move to the side away from the containing cavity 3 of the guide portion 2a, so as to avoid entering the containing cavity 3, and further avoid entering the gap between the cover body 1 and the exhaust pipe 20.

[0036] Compared with the prior art, the arrangement of the embodiment can effectively prevent combustible materials such as dry grass from entering the gap between the heat shield 10 and the exhaust pipe 20, thereby improving the safety performance of the vehicle.

[0037] In addition, when the heat shield 10 is applied to a vehicle, the front-rear direction is the front-rear direction of the vehicle, the up-down direction is the up-down direction of the vehicle, and the left-right direction is the left-right direction of the vehicle.

[0038] The guiding portion 2a can be opposite to the accommodating cavity 3 in the front-rear direction, which can mean that, when the guiding portion 2a is located at the front end of the cover body 1, in the orthographic projection on a plane (defined as a first plane) perpendicular to the front-rear direction, at least a part of the orthographic projection of the first opening and the orthographic projection of the guiding portion 2a coincide; when the guiding portion 2a is located at the rear end of the cover body 1, in the orthographic projection on the first plane, at least a part of the orthographic projection of the second opening and the orthographic projection of the guiding portion 2a coincide.

[0039] The guiding portion 2a provided at the front end of the cover body 1 can mean that the guiding portion 2a is provided on the front end face of the cover body 1, and the guiding portion 2a provided at the rear end of the cover body 1 can mean that the guiding portion 2a is provided on the rear end face of the cover body 1.

[0040] In an embodiment, the cover body 1 and the baffle 2 are integrally formed, which can improve the production efficiency of the heat shield 10.

[0041] In an embodiment, the accommodating cavity 3 forms an accommodating opening on the upper surface of the cover body 1, and the accommodating opening penetrates from the front end face of the cover body 1 to the rear end face of the cover body 1, which can facilitate the placement of the exhaust pipe 20 into the accommodating cavity 3 and the installation of the heat shield 10 on the vehicle body.

[0042] In an embodiment, at one end where the baffle 2 is located, a part of the opening formed by the accommodating cavity 3 and the baffle 2 are staggered in the front-rear direction. In subsequent use, the exhaust pipe 20 can be extended out of or into the accommodating cavity 3 from the position where the accommodating cavity 3 and the baffle 2 are staggered, thereby facilitating the use and installation of the heat shield 10.

[0043] When the baffle 2 is located at the front end of the cover body 1, at one end where the baffle 2 is located, the opening formed by the accommodating cavity 3 refers to the first opening; when the baffle 2 is located at the rear end of the cover body 1, at one end where the baffle 2 is located, the opening formed by the accommodating cavity 3 refers to the second opening.

[0044] At one end where the baffle 2 is located, a part of the opening formed by the accommodating cavity 3 and the baffle 2 are staggered in the front-rear direction, which actually means that, when the baffle 2 is located at the front end of the cover body 1, a part of the first opening is staggered with the baffle 2 located at the front end of the cover body 1 in the front-rear direction; when the baffle 2 is located at the rear end of the cover body 1, a part of the second opening is staggered with the baffle 2 located at the rear end of the cover body 1 in the front-rear direction.

[0045] In addition, the fact that a portion of the first opening is offset from the baffle 2 located at the front end of the cover 1 in the front-back direction means that in the orthographic projection on the first plane, a portion of the orthographic projection of the first opening does not overlap with the orthographic projection of the baffle 2 at the front end of the cover 1.

[0046] The second opening is offset from the baffle 2 located at the rear end of the cover 1 in the front-back direction, meaning that in the orthographic projection on the first plane, a portion of the orthographic projection of the second opening does not overlap with the orthographic projection of the baffle 2 at the rear end of the cover 1.

[0047] It should be understood that at the end where the baffle 2 is located, a portion of the opening formed by the receiving cavity 3 is offset from the baffle 2 in the front-back direction. This mainly means that at the end where the baffle 2 is located, a portion of the opening formed by the receiving cavity 3 is offset from the guide portion 2a in the front-back direction.

[0048] like Figure 1 and Figure 2 As shown, in one embodiment, the cover 1 includes a first partition 11 and a second partition 12; the lower end of the first partition 11 is connected to the lower end of the second partition 12; the first partition 11 and the second partition 12 are used to enclose and form a receiving cavity 3, and are respectively located on the left and right sides of the receiving cavity 3. Wherein, the first partition 11 and the second partition 12 are used to enclose and form the receiving cavity 3, meaning that: the first partition 11 and the second partition 12 can be directly connected to enclose and form the receiving cavity 3; or, the first partition 11 and the second partition 12 are only part of the structure enclosing and forming the receiving cavity 3, in which case they need to cooperate with other structures to further enclose and form the receiving cavity 3.

[0049] like Figure 1 and Figure 2 As shown, in one embodiment, the cover 1 further includes a third partition 13, which also serves to enclose and form a receiving cavity 3. The first partition 11 and the second partition 12 are respectively connected to the front and rear ends of the third partition 13, and both the first partition 11 and the second partition 12 are located above the third partition 13. It should be understood that the third partition 13 is only a part of the structure enclosing and forming the receiving cavity 3; it needs to cooperate with other structures to further enclose and form the receiving cavity 3. In this embodiment, the lower end of the first partition 11 is connected to the lower end of the second partition 12 through the third partition 13, that is, the lower ends of the first partition 11 and the lower ends of the second partition 12 are indirectly connected.

[0050] In addition, the first partition 11, the second partition 12 and the third partition 13 are connected to form a U-shaped structure, and the receiving cavity 3 is located between the first partition 11 and the second partition 12 and above the third partition 13.

[0051] In an implementable embodiment, the first partition plate 11, the second partition plate 12 and the third partition plate 13 are connected to form the accommodating cavity 3.

[0052] Of course, in other embodiments, the first partition plate 11, the second partition plate 12 and the third partition plate 13 need to be cooperated with other structures (defined as the first structure) to form the accommodating cavity 3. At this time, the first structure can be connected to the first partition plate 11 and the third partition plate 13 respectively to realize the connection of the first partition plate 11 and the third partition plate 13; or the first structure can be connected to the second partition plate 12 and the third partition plate 13 respectively to realize the connection of the second partition plate 12 and the third partition plate 13; or the first structure can be connected to the end of the first partition plate 11 away from the third partition plate 13; or the first structure can be connected to the end of the second partition plate 12 away from the third partition plate 13.

[0053] In addition, the first partition plate 11, the third partition plate 13 and the second partition plate 12 can be an integrally formed structure, which can be formed by bending a plate.

[0054] In this embodiment, the front end of the cover body 1 includes the front end of the first partition plate 11, the front end of the third partition plate 13 and the front end of the second partition plate 12, and the rear end of the cover body 1 includes the rear end of the first partition plate 11, the rear end of the third partition plate 13 and the rear end of the second partition plate 12.

[0055] In an embodiment, the first partition plate 11 can be a flat plate or a curved plate, the third partition plate 13 can be a flat plate or a curved plate, and the second partition plate 12 can be a flat plate or a curved plate.

[0056] As shown in the drawings, in an embodiment, the first partition plate 11 is provided with a reinforcing rib 4; and / or the third partition plate 13 is provided with a reinforcing rib 4; and / or the second partition plate 12 is provided with a reinforcing rib 4. In this way, the strength of the cover body 1 can be improved. Figure 1 The reinforcing rib 4 can form a groove on the outer surface of the cover body 1 and a protrusion on the inner surface of the cover body 1. The inner surface refers to the surface of the cover body 1 used to form the accommodating cavity 3, and the outer surface refers to the surface of the cover body 1 away from the accommodating cavity 3.

[0057] For the first partition plate 11, when the reinforcing rib 4 is provided thereon, the reinforcing rib 4 forms a groove on the surface thereof away from the second partition plate 12 and forms a protrusion on the surface thereof close to the second partition plate 12.

[0058] For the second partition plate 12, when the reinforcing rib 4 is provided thereon, the reinforcing rib 4 forms a groove on the surface thereof away from the first partition plate 11 and forms a protrusion on the surface thereof close to the first partition plate 11.

[0062] As shown in Figure 2 In an embodiment, the cover body 1 further comprises a first connecting plate 14 connected to the upper end of the first partition plate 11 and located on the side of the first partition plate 11 away from the second partition plate 12, the first connecting plate 14 is provided with a first connecting structure 141 for connecting the vehicle body; and / or, the cover body 1 further comprises a second connecting plate 15 connected to the upper end of the second partition plate 12 and located on the side of the second partition plate 12 away from the first partition plate 11, the second connecting plate 15 is provided with a second connecting structure 151 for connecting the vehicle body.

[0063] The first connecting structure 141 can be a first mounting hole penetrating the first connecting plate 14 in the up-down direction, during assembly, a corresponding bolt can pass through the first connecting plate 14 from the first mounting hole and cooperate with a threaded hole on the vehicle body, thereby realizing the connection of the first connecting structure 141 to the vehicle body, so that the heat shield 10 can be connected to the vehicle body.

[0064] In addition, the second connecting structure 151 can be a second mounting hole penetrating the second connecting plate 15 in the up-down direction, during assembly, a corresponding bolt can pass through the second connecting plate 15 from the second mounting hole and cooperate with a threaded hole on the vehicle body, thereby realizing the connection of the second connecting structure 151 to the vehicle body, so that the heat shield 10 can also be connected to the vehicle body.

[0065] As shown in Figure 2 In an embodiment, the guide portion 2a is connected to the front end of the third partition plate 13 and is inclined forward; and / or, the guide portion 2a is connected to the rear end of the third partition plate and is inclined backward.

[0066] The guide portion 2a is connected to the front end of the third partition plate 13 and is inclined forward, which means that the first end is connected to the front end of the third partition plate 13, and the distance between the guide portion 2a and the rear end of the third partition plate 13 gradually increases in the direction from the first end to the second end. At this time, the front end of the third partition plate 13 is provided with a baffle 2.

[0067] The guide portion 2a is connected to the rear end of the third partition plate and is inclined rearward, that is, the first end is connected to the rear end of the third partition plate, and the distance between the guide portion 2a and the front end of the third partition plate 13 gradually increases in the direction from the first end to the second end. At this time, the rear end of the third partition plate 13 is provided with the baffle 2.

[0068] In this embodiment, the baffle 2 is connected to the third partition plate 13, so that the baffle 2 is connected to the cover body 1.

[0069] In Figure 2 In the illustrated embodiment, the number of baffles is two, and at this time, the guide portion 2a of one baffle 2 (which is the first baffle 21) is connected to the front end of the third partition plate 13 and is inclined forward, and the guide portion 2a of the other baffle 2 (which is the second baffle 22) is connected to the rear end of the third partition plate 13 and is inclined rearward.

[0070] It should be understood that in this embodiment, the accommodating cavity 3 is located above the third partition plate 13, so that when the guide portion 2a is opposite to the accommodating cavity 3, the guide portion 2a is located above the third partition plate 13. At this time, the first end of the guide portion 2a is the lower end of the guide portion 2a, and the second end of the guide portion 2a is the upper end of the guide portion 2a. In addition, the second end of the guide portion 2a can be a free end, which can be provided in a suspended manner.

[0071] In addition, the guide portion 2a of the first baffle 21 is spaced from the first partition plate 11 and the second partition plate 12, and the guide portion 2a of the second baffle 22 is also spaced from the first partition plate 11 and the second partition plate 12. This is more convenient for the production of the heat insulation cover 10.

[0072] In an embodiment, the first baffle 21 does not protrude the lower surface of the third partition plate 13 in the direction from top to bottom.
