[0031] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Figure 1-Figure 3 The heat shield 100 for a post-processor according to the first embodiment of the utility model is described. The heat shield 100 can be used in a post-processor (not shown). In the following description of the application, the heat shield 100 is used in a post-processor as an example for detailed description.

[0032] like Figure 1 and Figure 2 As shown, the heat shield 100 for a post-processor according to the first embodiment of the utility model comprises a body 1, at least one group of first heat dissipation holes 2 and a second heat dissipation holes 3.

[0033] Specifically, the body 1 is along a first direction (eg Figure 1 The two ends of the first heat dissipation hole group 2 (in the up and down direction shown) are respectively the first end 11 and the second end 12, the first heat dissipation hole group 2 includes a plurality of first heat dissipation holes 21, and the first heat dissipation holes 21 are formed on the body 1. In the description of the utility model, the meaning of "plurality" is two or more. The plurality of first heat dissipation holes 21 constitute a plurality of first sub-heat dissipation hole groups 211 and a plurality of second sub-heat dissipation hole groups 212, and the plurality of first sub-heat dissipation hole groups 211 and the plurality of second sub-heat dissipation hole groups 212 are arranged alternately along the first direction, the first sub-heat dissipation hole group 211 includes at least one first sub-heat dissipation hole 2111, and the second sub-heat dissipation hole group 212 includes at least one second sub-heat dissipation hole 2121, and the extension direction of the first sub-heat dissipation hole 2111 is perpendicular to the extension direction of the second sub-heat dissipation hole 2121.

[0034] For example, in Figure 1 and Figure 2 In the example, the first end 11 is the lower end of the body 1, and the second end 12 is the upper end of the body 1. Figure 1 Seven first heat dissipation hole groups 211 and six second heat dissipation hole groups 212 are shown, and the seven first heat dissipation hole groups 211 and the six second heat dissipation hole groups 212 are staggered in the up and down direction. The cross-sectional shape of the first heat dissipation hole 21 can be elliptical, oblong, etc. Therefore, when the heat insulation cover 100 is used for a post-processor, the arrangement of the first sub-heat dissipation hole group 211 and the second sub-heat dissipation hole group 212 is consistent with the shape of the components around the post-processor (such as the pedal), thereby improving the aesthetics of the heat insulation cover 100, and also improving the overall aesthetics of the post-processor, thereby improving the user's visual experience. In addition, when the heat insulation cover 100 is used on the post-processor, the first heat dissipation hole 21 is arranged in the thickness direction of the body 1 (for example, Figure 1The heat shield 100 (in the front-to-back direction) penetrates the two side surfaces of the body 1, so that while ensuring the protective effect of the heat shield 100 on the post-processor, the heat shield 100 can release the heat generated during the operation of the post-processor, avoid the formation of heat focus inside the post-processor, and thus avoid the post-processor from being damaged by its own high temperature, and the wiring harness and sensor on the post-processor from being thermally damaged, thereby extending the service life of the post-processor. In addition, the heat shield 100 can isolate the post-processor from direct contact with the components around the post-processor, thereby facilitating the normal use of the post-processor and the components around the post-processor, thereby extending the service life of the vehicle.

[0035] Combination Figure 1 The second heat dissipation hole group 3 includes a plurality of second heat dissipation holes 31, which are formed on the body 1 and adjacent to the first end 11. The plurality of second heat dissipation holes 31 are arranged along the second direction (eg Figure 1 The left and right directions shown in the figure are arranged at intervals, and the second direction is perpendicular to the first direction. Figure 1 In the example, the cross-sectional shape of the second heat dissipation hole 31 is substantially elliptical. With such a configuration, a wiring harness is installed on the post-processor, and the second heat dissipation hole 31 can be used to dissipate heat from the wiring harness on the post-processor, thereby increasing the heat dissipation speed of the wiring harness on the post-processor, avoiding damage to the wiring harness on the post-processor, thereby increasing the performance of the heat shield 100, and facilitating the normal use of the post-processor for a long time. In addition, the heat shield 100 has a simple structure and is easy to produce, thereby increasing the production of the heat shield 100 and also increasing the production efficiency of the heat shield 100.

[0036] According to the heat shield 100 for the post-processor of the utility model, when the heat shield 100 is used for the post-processor, the first heat dissipation hole group 2 and the parts around the post-processor (such as the foot pedal) are consistent in shape, thereby improving the aesthetics of the heat shield 100 and the post-processor, thereby improving the user experience. In addition, the heat shield 100 can isolate the post-processor from contact with the parts around the post-processor, and can also dissipate the heat in the post-processor, thereby extending the service life of the post-processor. In addition, the second heat dissipation hole group 3 can dissipate the heat of the wiring harness on the post-processor, so that the post-processor can be used normally for a long time.

[0037] According to some embodiments of the present invention, referring to Figure 1 and Figure 2 , from the second end 12 toward the first end 11, the first sub-heat dissipation hole 2111 extends obliquely toward the side away from the center of the body 1, and the second sub-heat dissipation hole 2121 extends obliquely toward the side close to the center of the body 1. For example, Figure 1 and Figure 2In the example, a group of first heat dissipation holes 2 near the leftmost edge of the main body 1 is taken as an example for explanation. From the top to the bottom, the first sub-heat dissipation hole 2111 extends obliquely to the left, and the second sub-heat dissipation hole 2121 extends obliquely to the right. Such a setting effectively ensures that the first sub-heat dissipation hole 2111 and the second sub-heat dissipation hole 2121 are vertical, thereby effectively ensuring that the arrangement of the first sub-heat dissipation hole 2111 and the second sub-heat dissipation hole 2121 and the shape of the components around the post-processor (such as the pedal) are coordinated, thereby improving the coordination and consistency between the post-processor and the components around the post-processor, thereby improving the visual experience of the user. In addition, the structural arrangement of the first sub-heat dissipation hole 2111 and the second sub-heat dissipation hole 2121 is reasonable, thereby effectively ensuring the structural strength of the main body 1, thereby improving the structural strength of the heat insulation cover 100, and improving the protective effect of the heat insulation cover 100 on the post-processor. Moreover, the space of the main body 1 can also be reasonably utilized to improve the surface area utilization rate of the main body 1.

[0038] According to some embodiments of the present invention, referring to Figure 1 and Figure 2 There are multiple first sub-heat dissipation holes 2111, and the multiple first sub-heat dissipation holes 2111 are arranged at intervals along the first direction (i.e., the up-down direction). From the second end 12 toward the first end 11, the lengths of the multiple first sub-heat dissipation holes 2111 of the first sub-heat dissipation hole group 211 decrease successively. For example, Figure 1 and Figure 2 In the example, when there are three first sub-heat dissipation holes 2111, the lengths of the three first sub-heat dissipation holes 2111 arranged from top to bottom decrease in sequence. In this way, when the plurality of first sub-heat dissipation holes 2111 and the second sub-heat dissipation holes 2121 are arranged alternately along the first direction, the utilization rate of the first sub-heat dissipation hole group 211 on the body 1 is improved, thereby increasing the occupied area of ​​the first sub-heat dissipation hole group 211 while ensuring the structural strength of the heat shield 100, further improving the heat dissipation effect of the heat shield 100, and thereby extending the service life of the post-processor.

[0039] According to other embodiments of the present invention, Figure 1 and Figure 2 There are multiple second sub-heat dissipation holes 2121, and the multiple second sub-heat dissipation holes 2121 are arranged at intervals along the first direction. From the second end 12 toward the first end 11, the lengths of the multiple second sub-heat dissipation holes 2121 of the second sub-heat dissipation hole group 212 decrease in sequence. For example, Figure 1 and Figure 2In the example, when there are three second sub-heat dissipation holes 2121, the lengths of the three second sub-heat dissipation holes 2121 from top to bottom decrease in sequence. In this way, when the plurality of second sub-heat dissipation holes 2121 and the first sub-heat dissipation holes 2111 are arranged in an interlaced manner in the up-down direction, the utilization rate of the second sub-heat dissipation hole group 212 on the body 1 is improved, thereby increasing the occupied area of ​​the second sub-heat dissipation hole group 212 while ensuring the structural strength of the heat shield 100, further improving the heat dissipation effect of the heat shield 100, and thereby extending the service life of the post-processor.

[0040] According to some further embodiments of the present invention, referring to Figure 1 and Figure 2 , there are multiple first sub-heat dissipation holes 2111 and multiple second sub-heat dissipation holes 2121, and the multiple first sub-heat dissipation holes 2111 are arranged at intervals along the first direction, and the lengths of the multiple first sub-heat dissipation holes 2111 of the first sub-heat dissipation hole group 211 decrease from the second end 12 toward the first end 11, and the multiple second sub-heat dissipation holes 2121 are arranged at intervals along the first direction, and the lengths of the multiple second sub-heat dissipation holes 2121 of the second sub-heat dissipation hole group 212 decrease from the second end 12 toward the first end 11. For example, Figure 1 and Figure 2 In the example, when there are three first sub-heating holes 2111 and when there are three second sub-heating holes 2121, the three first sub-heating holes 2111 of the first sub-heating hole group 211 and the three second sub-heating holes 2121 of the second sub-heating hole group 212 are alternately arranged in the up and down directions, and from top to bottom, the lengths of the three first sub-heating holes 2111 gradually decrease, and the length components of the three second sub-heating holes 2121 decrease.

[0041] Thus, when a plurality of first sub-heat dissipation holes 2111 and a plurality of second sub-heat dissipation holes 2121 are arranged in an interlaced manner in the up-down direction, the utilization rate of the first sub-heat dissipation hole group 211 and the second sub-heat dissipation hole group 212 on the body 1 is improved, thereby increasing the occupied area of ​​the first sub-heat dissipation hole group 211 and the second sub-heat dissipation hole group 212 while ensuring the structural strength of the heat shield 100, further improving the heat dissipation effect of the heat shield 100, and thereby extending the service life of the post-processor. However, it is not limited thereto. It should be noted that the number and arrangement of the first sub-heat dissipation holes 2111 and the second sub-heat dissipation holes 2121 can be specifically set according to actual use to better meet practical applications. For example, the first sub-heat dissipation hole group 211 near the first end 11 includes one first sub-heat dissipation hole 2111, the first sub-heat dissipation hole group 211 near the second end 12 includes two first sub-heat dissipation holes 2111, the multiple first sub-heat dissipation hole groups 211 at the middle position of the main body 1 respectively include three first sub-heat dissipation holes 2111, and the multiple second sub-heat dissipation hole groups 212 respectively include three second sub-heat dissipation hole groups 212.

[0042] According to some embodiments of the present invention, referring to Figure 1 and Figure 2 , the projection of the second sub-heat dissipation hole group 212 on the plane perpendicular to the second direction (i.e., the left-right direction) (i.e., the plane where the front-back direction is located) overlaps at least a part of the projection of the first sub-heat dissipation hole group 211 on the plane perpendicular to the second direction. Figure 1 and Figure 2 In the example, a plurality of first sub-heat dissipation holes 2111 are arranged at intervals along the extension direction of the second sub-heat dissipation holes 2121, and a plurality of second sub-heat dissipation holes 2121 are arranged at intervals along the extension direction of the first sub-heat dissipation holes 2111. The projection of the upper portion of the second sub-heat dissipation hole group 212 on the plane where the front-to-back direction is located overlaps with the projection of the lower portion of the first sub-heat dissipation hole group 211 located to the upper left of the second sub-heat dissipation hole group 212 on the plane where the front-to-back direction is located, and the projection of the lower portion of the second sub-heat dissipation hole group 212 on the plane where the front-to-back direction is located overlaps with the projection of the upper portion of the first sub-heat dissipation hole group 211 located to the lower left of the second sub-heat dissipation hole group 212 on the plane where the front-to-back direction is located.

[0043] In this way, the first sub-heat dissipation hole group 211 and the second sub-heat dissipation hole group 212 are neatly arranged in the up-down direction, thereby improving the neatness of the arrangement of the first heat dissipation hole group 2, improving the aesthetics of the first heat dissipation hole group 2, and further improving the aesthetics of the heat shield 100. In addition, the first heat dissipation hole group 2 and the second heat dissipation hole group 3 are reasonably and compactly arranged, further improving the utilization rate of the surface of the body 1, and further improving the heat dissipation performance of the heat shield 100.

[0044] According to some embodiments of the present invention, referring to Figure 2 The edge of each first heat dissipation hole 21 is provided with a protrusion 213 extending along the circumference of the first heat dissipation hole 21, and the protrusion 213 protrudes from the surface of the body 1. Figure 2 In the example, the protrusion 213 is turned out toward the surface of the main body 1 along the edge of the first heat dissipation hole 21. With this arrangement, the protrusion 213 is visually impactful and aesthetically pleasing, and its shape further fits the shape of the components around the post-processor, thereby further improving the overall aesthetics of the post-processor. In addition, the protrusion 213 also has an anti-slip effect, which can prevent the user from slipping when stepping on the heat insulation cover 100, thereby improving the safety of the use of the heat insulation cover 100. In addition, the protrusion 213 further strengthens the structural strength of the edge of the first heat dissipation hole 21, thereby further improving the structural strength of the heat insulation cover 100, and helping to further extend the service life of the heat insulation cover 100.

[0045] Further, refer to Figure 1 , the second heat dissipation hole 31 extends vertically along the first direction (ie, the up-down direction). Figure 1In the example, the second heat dissipation hole 31 has a simple structure and is easy to form, thereby improving the production efficiency of the second heat dissipation hole 31, and further improving the production efficiency of the heat insulation cover 100. In addition, the structure of the second heat dissipation hole 31 is reasonably arranged, thereby improving the structural strength of the body 1 around the second heat dissipation hole 31, and further improving the structural strength of the heat insulation cover 100. In addition, it is also convenient to arrange the plurality of second heat dissipation holes 31 compactly along the left and right directions, thereby increasing the occupied area of ​​the plurality of second heat dissipation holes 31 on the body 1 while ensuring the structural strength of the body 1, improving the utilization rate of the heat insulation cover 100, and further improving the heat dissipation effect of the heat insulation cover 100.

[0046] According to some embodiments of the present invention, referring to Figure 1 and Figure 2 , the third direction of the main body 1 (for example Figure 1 At least one groove 13 is formed on one side surface (i.e., the front-to-back direction shown in the figure), the groove 13 extends along the first direction (i.e., the up-down direction), and a plurality of mounting holes 131 are formed on the bottom wall of the groove 13. The plurality of mounting holes 131 are arranged at intervals along the first direction, and the first direction, the second direction, and the third direction are orthogonal.

[0047] For example, in Figure 1 and Figure 2 In the example, the groove 13 is formed on the side surface of the body 1 provided with the first heat dissipation hole group 2, and the groove 13 is recessed in the surface of the body 1, that is, the groove 13 is recessed forward, and the mounting hole 131 passes through the bottom wall of the groove 13. In this way, the mounting hole 131 is convenient for connecting the heat shield 100 with the post-processor, for example, the fastener (such as a bolt) passes through the mounting hole 131 and is connected to the corresponding position of the post-processor, thereby improving the installation efficiency of the heat shield 100 and the post-processor, and then improving the installation efficiency of the vehicle. In addition, the groove 13 facilitates the distinction between the mounting hole 131 and the first heat dissipation hole 21, so that in the process of installing the heat shield 100 and the post-processor, it is easy to find the mounting hole 131, thereby shortening the time to find the mounting hole 131, reducing the difficulty of installation, and improving the efficiency of installation.

[0048] According to some embodiments of the present invention, referring to Figure 3 A avoidance groove 14 is formed on the other side surface of the main body 1 along the third direction (i.e., the front-to-back direction), the first heat dissipation hole group 2 is arranged on the bottom wall of the avoidance groove 14, and the second heat dissipation hole group 3 is arranged on the side wall of the avoidance groove 14. The first direction, the second direction and the third direction are orthogonal.

[0049] For example, in Figure 3In the example, the avoidance groove 14 is formed on the front surface of the body 1, the side wall of the avoidance groove 14 is inclined, and the cross-sectional area of ​​the bottom wall of the avoidance groove 14 is smaller than the cross-sectional area of ​​the open part of the avoidance groove 14, that is, the body 1 is in a contracted state from the front to the back. In this way, during the installation of the heat shield 100 and the post-processor, the avoidance groove 14 can avoid some parts of the post-processor, thereby facilitating the installation of the heat shield 100 and the post-processor and improving the installation efficiency. In addition, the circumference of the body 1 is smoother, and the shape of the heat shield 100 is more distinct, thereby further improving the aesthetics of the heat shield 100.

[0050] Optionally, refer to Figure 1 , there are a plurality of first heat dissipation hole groups 2, a plurality of grooves 13, and the plurality of first heat dissipation holes 21 and the plurality of grooves 13 are arranged alternately along the second direction (ie, the left-right direction). Figure 1 In the example, there are four first heat dissipation hole groups 2, three grooves 13, and one groove 13 between two adjacent first heat dissipation hole groups 2. Thus, the grooves 13 separate the multiple first heat dissipation hole groups 2, avoiding the first heat dissipation hole groups 2 from being arranged compactly and affecting the visual sense, and also increasing the distance between the multiple first heat dissipation hole groups 2, thereby improving the overall aesthetics of the heat shield 100, reducing the number of first heat dissipation holes 21, and improving the structural strength of the heat shield 100, thereby improving the protective effect of the heat shield 100 on the post-processor and extending the service life of the heat shield 100.

[0051] The post-processor (not shown) according to the second embodiment of the utility model comprises the heat shield 100 for the post-processor according to the first embodiment of the utility model. The heat shield 100 covers the post-processor.

[0052] According to the post-processor of the present invention, by adopting the heat shield 100, the consistency of the shape of the post-processor and the components around the post-processor is improved, thereby improving the aesthetics of the post-processor.

[0053] A vehicle (not shown) according to an embodiment of the third aspect of the utility model comprises a post-processor according to an embodiment of the second aspect of the utility model.

[0054] According to the vehicle of the utility model, the overall aesthetics of the vehicle is improved by adopting the above-mentioned post-processor. In addition, the heat shield 100 has made great progress in shape while protecting the post-processor, and the shape is more beautiful, which plays a positive role in the aesthetics of the vehicle.

[0055] Other components and operations of the post-processor and the vehicle according to the embodiment of the present invention are well known to those skilled in the art and will not be described in detail here.
