Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, in particular to a heat insulation mechanism for an automobile exhaust system. Background Art

[0002] Heat insulation structures need to be provided at some positions of the exhaust pipe of the automobile exhaust system. When the exhaust pipe is operating, it will release a large amount of heat. If heat insulation treatment is not carried out, this heat may damage surrounding rubber pipelines, resin parts, wires and other components, affecting the normal operation of the vehicle.

[0003] In the prior art, the heat insulation method is to completely wrap the circumferential surface of the exhaust pipe at the corresponding position with heat insulation cotton (reference can be made to the published (announced) number: CN112112719A, a heat insulation device for an automobile exhaust pipe, and the published (announced) number: CN202789058U, an automobile exhaust pipe heat insulation cotton packaging device). This wrapping method has the following disadvantages. The setting of the heat insulation cotton is not flexible enough. Because some parts of the exhaust pipe need to be completely wrapped, while some parts only need partial wrapping. If complete wrapping is carried out at the parts that only need partial wrapping, it will instead affect the heat dissipation of the exhaust pipe, easily cause heat accumulation, and lead to a higher temperature around the exhaust pipe. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the disadvantage that the setting of the heat insulation cotton in the prior art is not flexible enough, and to provide a heat insulation mechanism for an automobile exhaust system.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A heat insulation mechanism for an automobile exhaust system includes a support plate and a plurality of heat insulation sheets. The support plate is fixed on the outer peripheral side of the exhaust pipe. A plurality of uniformly distributed mounting holes are formed in the support plate. A plurality of locking parts are connected to the heat insulation sheets. The heat insulation sheets are fixedly connected to the mounting holes of the support plate through the locking parts.

[0007] The locking part is an inverted buckle. One end of the inverted buckle is fixedly connected to the heat insulation sheet, and the other end of the inverted buckle is snap-connected to the mounting hole.

[0008] The locking part includes a connecting rod penetrating through the heat insulation sheet, a head located at one end of the connecting rod, and a tail block located at the other end of the connecting rod. The head and the tail block are respectively located on both sides of the heat insulation sheet. The mounting hole is a rectangular hole. The tail block can pass through the rectangular hole and be limited on the side of the support plate close to the exhaust pipe.

[0009] A notch is formed on the side of the support plate facing the mounting hole and close to the exhaust pipe. The depth of the notch is greater than the thickness of the tail block.

[0010] On one side of the head away from the tail block, there is a flat groove; or on one side of the head away from the tail block, there is a cross groove.

[0011] The support plate is fixed on the exhaust pipe by fasteners.

[0012] The fasteners are metal ties.

[0013] The heat insulation sheet is heat insulation cotton.

[0014] For the heat insulation mechanism of an automobile exhaust system proposed by the present utility model, the beneficial effects are as follows: the heat insulation sheets of the device are more flexible in setting. If full wrapping is required, heat insulation sheets with full wrapping are set on the support plate; if partial wrapping is required, heat insulation sheets with partial wrapping are set on the support plate. The size of the heat insulation sheet can be arbitrarily cut according to requirements, and the heat insulation sheet is simple, convenient and flexible to fix. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0021] Refer to Figures 1-4 , a heat insulation mechanism for an automobile exhaust system, including a support plate 2 and a plurality of heat insulation sheets 5. The support plate 2 is fixed on the outer peripheral side of the exhaust pipe 1. A plurality of uniformly distributed mounting holes 4 are provided on the support plate 2. A plurality of locking parts 6 are connected to the heat insulation sheet 5. The heat insulation sheet 5 is fixedly connected to the mounting holes 4 of the support plate 2 through the locking parts 6.

[0022] Refer to Figure 1, when the device is in use, first fix the support plate 2 on the exhaust pipe 1, and the support plate 2 is preset with mounting holes 4. Then, according to the requirements of the heat insulation part, fix heat insulation sheets 5 of different sizes, shapes and dimensions through locking fasteners 6 respectively. In this way, the setting of the heat insulation sheets 5 is more flexible. If full wrapping is required, a fully wrapped heat insulation sheet is set on the support plate 2. If partial wrapping is required, a partially wrapped heat insulation sheet is set on the support plate 2. The size of the heat insulation sheet can be arbitrarily cut according to the needs, and the heat insulation sheet is simple, convenient and flexible to fix.

[0023] As an implementation method, the locking fastener 6 is an inverted buckle. One end of the inverted buckle is fixedly connected to the heat insulation sheet 5, and the other end of the inverted buckle is snap-connected to the mounting hole 4. The heat insulation sheet 5 and the support plate 2 are fixed together by a direct snap connection, which is simple and convenient to snap.

[0024] As another implementation method, refer to Figures 2-4 , the locking fastener 6 includes a connecting rod 9 passing through the heat insulation sheet 5, a head 8 located at one end of the connecting rod 9, and a tail block 10 located at the other end of the connecting rod 9. For example, the tail block 10 is a rectangular block or a wedge-shaped block. The head 8 and the tail block 10 are respectively located on both sides of the heat insulation sheet 5. The mounting hole 4 is a rectangular hole, and the tail block 10 can pass through the rectangular hole and be limited on the side of the support plate 2 close to the exhaust pipe 1.

[0025] When fixing, refer to Figure 3 , first make the tail block 10 parallel and facing the mounting hole 4, then make the tail block 10 pass through the mounting hole 4, and then rotate the head 8 to make the tail block 10 rotate 90°, so that the tail block 10 and the mounting hole 4 are in a cross-shaped state, and the tail block 10 is limited at the bottom end of the mounting hole 4.

[0026] Refer to Figure 4 , a notch 7 is opened on the side of the support plate 2 facing the mounting hole 4 and close to the exhaust pipe 1. The depth of the notch 7 is greater than the thickness of the tail block 10, so as to prevent the tail block 10 from contacting the exhaust pipe 1 and facilitate the installation of the tail block 10.

[0027] In order to facilitate the rotation of the tail block 10, a flat groove is provided on the side of the head 8 away from the tail block 10; or a cross groove is provided on the side of the head 8 away from the tail block 10, and the tail block 10 is rotated by screwing the head 8 with a cross screwdriver or a flat screwdriver.

[0028] The support plate 2 is fixed on the exhaust pipe 1 through a fastener 3.

[0029] As an implementation method, the support plate 2 is made of a bendable high-temperature resistant plastic plate or metal plate. During installation, the support plate 2 is bent and wrapped around the exhaust pipe 1, and then the support plate 2 is fixed on the exhaust pipe 1 through a metal tie.

[0030] As an implementation method, the heat insulation sheet 5 is heat insulation cotton.
