[0002] The suspension system of the automobile power assembly is a key system for improving the comfort of the automobile and reducing the noise of the automobile, and the vibration isolation component of the suspension system is the main spring rubber, which is made of natural rubber and is extremely sensitive to high temperature environment. The engine compartment layout of the existing longitudinal fuel vehicle model is usually relatively compact, and the exhaust system is usually above the engine suspension, and the distance is relatively close, which will cause the engine suspension to work in a high temperature environment for a long time, so that the main spring rubber of the engine suspension is prone to aging failure and cracking, thereby causing comfort problems such as vehicle vibration and abnormal noise, which is easy to bring a lot of discomfort to passengers.

[0003] And the existing suspension heat shield is relatively bulky in order to achieve the heat insulation effect, which increases the weight of the vehicle. CONTENT OF THE UTILITY MODEL

[0004] Therefore, the present application provides an engine suspension heat shield and a vehicle, which solves the problem of the bulkiness of the existing suspension heat shield by using the engine suspension heat shield surrounded by the rigid heat shield body and the flexible heat shield cloth, thereby reducing the weight of the vehicle.

[0005] In order to achieve the above purpose, the present application provides the following technical scheme:

[0030] This application provides an engine mount heat shield and a vehicle. By using a rigid heat shield body and a flexible heat shield cloth to form an engine mount heat shield, the problem of the bulkiness of existing heat shields is solved, and the weight of the whole vehicle is reduced.

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] like Figures 1-3 As shown, the engine mount heat shield provided in this application includes:

[0033] The heat insulation cover 1 is made of a rigid material (such as aluminum sheet);

[0034] The heat insulation cover 2 is made of a flexible material (such as aluminum foil);

[0035] The heat shield 1 and the heat shield cloth 2 are fixedly connected and form an engine suspension heat shield.

[0036] The engine mount 5 heat insulation device of this application consists of two parts: a rigid heat insulation cover 1 and a flexible heat insulation cloth 2. The heat insulation cover 1 and the heat insulation cloth 2 are fixedly connected by rivets 3 or other connection methods. The flexible heat insulation cloth 2 replaces part of the rigid heat insulation cover 1, making the weight of the entire heat insulation cover lighter. With the rigid aluminum cover as the frame, the flexible heat insulation cloth 2 is supported and can be opened, making it less prone to deformation. The shape and strength of the entire heat insulation cover 1 are guaranteed. Its structure is simple, the heat insulation effect is good, and the manufacturing cost is low.

[0037] In a preferred embodiment, such as Figures 1-3 As shown, the rigid heat insulation cover 1 includes a cover top 11 and a cover side portion 12 extending downward from a portion of the cover top 11. The cover side portion 12 further includes a side main portion 121 and a side connecting portion 122. Smooth transition sections are provided between the cover top 11 and the side main portion 121, between the cover top 11 and the side connecting portion 122, and between the side main portion 121 and the side connecting portion 122. The heat insulation cover 2 includes a cover top 21 and a cover side portion 22 extending downward from a portion of the cover top 11. The cover side portion 22 includes a flat portion 221 and an arc-shaped portion 222. Smooth transition sections are provided between the cover top 21 and the flat portion 221, between the cover top 21 and the arc-shaped portion 222, and between the flat portion 221 and the arc-shaped portion 222.

[0038] The top 11 of the cover body and the top 21 of the cover cloth are connected to each other and partially overlap to form the top of the engine mount heat shield; the side part 12 of the cover body and the side part 22 of the cover cloth are connected to each other and partially overlap to form the side part of the engine mount heat shield, thereby forming a complete cover body shape. The side connecting part 122 and the flat part 221 are connected to each other and partially overlap. The side connecting part 122 is provided to provide connection support for the flat part 221, so that the arc-shaped part 222 of the heat shield cloth 2 is supported and opened.

[0039] In a preferred embodiment, such as Figure 2 As shown, the top 11 of the cover is a convex shape; specifically, the top 11 of the cover can be approximated as a convex quadrilateral, such as... Figure 3 As shown, the top of the cover 21 is concave. Specifically, the top of the cover 21 can be regarded as a C-shape, with one side of the convex quadrilateral corresponding to the opening of the C-shape, and the other three sides of the convex quadrilateral facing the part of the C-shape other than the opening.

[0040] While ensuring the connection strength between the top 11 of the cover body and the top 21 of the cover cloth, the area where the top 11 of the cover body and the top 21 of the cover cloth are connected and overlapped can be minimized, because reducing the overlap can reduce the amount of material used and reduce the weight.

[0041] In a preferred embodiment, such as Figure 2 and Figure 3 As shown, in order to minimize the rigid parts and increase the flexible parts in the engine mount heat shield, and to reduce the overlap between the heat shield body 1 and the heat shield cloth 2, so as to reduce material usage and weight, the area of ​​the side part 22 of the cloth is larger than the area of ​​the side part 12 of the shield body. That is, the area of ​​the side body part 121 is smaller, and the area of ​​the side part 22 of the cloth formed by the flat part 221 and the arc-shaped part 222 is larger. Similarly, the length of the side connecting part 122 can be set to ensure the connection strength, so it can be set to be smaller, and the area of ​​the flat part 221 is set to be larger. That is, the area of ​​the side connecting part 122 is smaller than the area of ​​the flat part 221.

[0042] In a preferred embodiment, such as Figure 1 , Figure 4 and Figure 5 As shown, the heat insulation cover 1 and the heat insulation cover 2 are fixedly connected by rivets 3. The top 11 and the side connecting part 122 of the heat insulation cover 1 are respectively provided with first rivet holes 13; the top 21 and the flat part 221 of the heat insulation cover 2 are respectively provided with second rivet holes 23. The connection by rivets 3 is simple and easy to operate and the connection strength can be guaranteed. A washer 4 is also provided between the rivet head of the rivet 3 and the heat insulation cover 2 to increase the riveting area between the heat insulation cover 1 and the heat insulation cover 2.

[0043] In a preferred embodiment, to ensure the secure and reliable connection between the heat insulation cover 1 and the heat insulation fabric 2 after riveting, such as... Figure 5 As shown, the distance D1 between the outer periphery of the gasket 4 and the edge of the heat insulation cover 2 satisfies: D1≥10mm. This avoids the heat insulation cover 2 from being damaged due to uneven force at the rivet 3 caused by an excessively small distance between the outer periphery of the gasket 4 and the edge of the heat insulation cover 2. And / or, the difference between the diameter A1 of the gasket 4 and the diameter A2 of the rivet head of the rivet 3 satisfies: A1-A2≥2mm, so as to ensure that the gasket 4 has sufficient bearing area to make the heat insulation cover 2 under the gasket 4 bear force evenly.

[0044] In a preferred embodiment, such as Figure 6 and Figure 7As shown, the engine mount heat shield is positioned between the engine mount 5 and the engine connecting bracket 6; the lower surface of the top of the heat shield body 1 and / or the top of the heat shield cloth 2 abuts against the top surface of the engine mount 5, and the upper surface of the top of the heat shield body 1 and / or the top of the heat shield cloth 2 abuts against the lower end face of the engine connecting bracket 6, thereby ensuring that the engine mount heat shield is in the Z-direction ( Figure 6 The engine mount 5 is fixed and positioned in the Z direction. Specifically, the upper end face of the engine mount 5 is provided with connecting bolts 51, the top 11 of the cover is provided with through holes 111, and the engine connecting bracket 6 is also provided with through holes 111. The connecting bolts 51 pass through the through holes 111 of the top 11 of the cover and the through holes 111 of the engine connecting bracket in sequence and are fixed with nuts to achieve a fixed connection between the engine mount 5, the engine mount heat shield and the engine connecting bracket 6.

[0045] In a preferred embodiment, such as Figure 6 As shown, since the width of the mounting portion 53 of the engine mount 5 is greater than the width of the engine mount heat shield, the lower edge of the engine mount heat shield is prone to touching the upper surface of the mounting portion 53 of the engine mount 5 when it tends to move downwards. To avoid the engine moving in the Z-direction ( Figure 6 When the engine mount heat shield moves violently up and down in the Z direction, it rubs against the engine mount 5 and is damaged. The gap D2 between the lower edge of the engine mount heat shield and the mounting part 53 of the engine mount 5 in the Z direction satisfies: D2≥15mm.

[0046] In a preferred embodiment, such as Figure 2 , Figure 4 , Figure 6 As shown, a positioning hole 112 is provided on the top of the heat insulation cover 1, and a positioning post 52 that mates with the positioning hole 112 is provided on the top surface of the engine mount 5.

[0047] To prevent the engine mount heat shield from rotating after assembly with the engine mount 5 and to maintain the correct installation angle, a positioning hole 112 is provided on the top of the heat shield 1, and a positioning post 52 is correspondingly provided on the top surface of the engine mount 5, with the positioning post 52 passing through the positioning hole 112. The number of positioning holes 112 is usually one or more, determined in conjunction with the positioning post 52 on the inner core of the engine mount 5. In this design, two positioning holes 112 are designed, and the two positioning holes 112 are respectively located on one side of the through hole 111.

[0048] This application also provides a vehicle including the aforementioned engine mount heat shield. By configuring the aforementioned engine mount heat shield assembly, the vehicle of this application reduces the overall vehicle weight.
