Description

Technical Field

[0001] The present application belongs to the technical field of automobile parts, and specifically relates to a heat insulation board installation structure and an automobile. Background Art

[0002] Heat shields are a crucial component of the exhaust system, shielding it from heat and preventing damage to surrounding components that could lead to malfunctions. Aluminum is often used for heat shields due to its excellent formability and thermal insulation properties. Furthermore, to improve vehicle fuel economy, heat shields are typically designed to be thinner, typically 0.5mm-1mm.

[0003] In the prior art, a heat shield is usually fixed to the protected component or the vehicle body or frame near the protected component by mounting bolts; after the mounting bolts are tightened, the mounting portion of the heat shield is pressed against the flange surface of the mounting bolts, thereby fixing the heat shield to the mounting surface.

[0004] The inventors discovered that the vibrations generated during vehicle driving will gradually transform into vibrations of the heat insulation board, and this vibration will act on the mounting bolts, causing shear forces to be generated at the contact edges between the mounting bolt flanges and the heat insulation board. After the vehicle has been running for a long time, the edges of the contact areas between the heat insulation board and the mounting bolt flanges will crack or break due to the shear forces. Moreover, the heat insulation board will lose its heat insulation function after cracking or breaking, causing thermal damage to surrounding components. In severe cases, it may even cause fires such as spontaneous combustion of the vehicle, reducing the safety of the vehicle during driving. Utility Model Content

[0005] The embodiments of the present application provide a heat insulation board mounting structure and a vehicle, which are intended to avoid shear forces generated between the flange surface of the mounting bolts and the contact edge of the heat insulation board, which could cause the heat insulation board to crack or break, thereby extending the service life of the heat insulation board, ensuring the heat insulation effect of the heat insulation board, and ensuring the safety of the vehicle during driving.

[0006] To achieve the above objectives, the technical solution adopted in this application is:

[0007] Provided is a heat insulation board installation structure, comprising:

[0008] The mounting hole is opened on the heat insulation board;

[0009] A mounting bolt is inserted into the mounting hole and threadedly connected to the mounting surface; the mounting bolt has a limiting end suitable for abutting the thermal insulation board;

[0010] a positioning sleeve, which is sleeved on the outer periphery of the mounting bolt, and one end of the positioning sleeve abuts against the limiting end head; and

[0011] An elastic ring is sleeved on the outer periphery of the positioning sleeve and is embedded in the mounting hole.

[0012] In a possible implementation, the positioning sleeve includes:

[0013] an inner sleeve, sleeved on the outer periphery of the mounting bolt; and

[0014] An outer sleeve is sleeved on the outer circumference of the inner sleeve, and the elastic ring is sleeved on the outer circumference of the outer sleeve;

[0015] Wherein, the inner peripheral wall of the outer sleeve is provided with a first concave annular groove, and the outer peripheral wall of the inner sleeve is provided with a first convex annular portion embedded in the first concave annular groove.

[0016] In a possible implementation, the inner sleeve has a first limiting ring extending radially outward, and the outer sleeve has a second limiting ring extending radially outward.

[0017] When the elastic ring is sleeved on the outer periphery of the outer sleeve and the first convex ring portion is embedded in the first concave ring groove, the first limiting ring and the second limiting ring respectively abut against two ends of the elastic ring.

[0018] In one possible implementation, when the first convex ring portion is embedded in the first concave ring groove, a reserved gap is formed between the outer sleeve and the first limiting ring, so that when the elastic ring is placed on the outer periphery of the outer sleeve, the elastic ring is suitable for elastic deformation and embedding into the reserved gap.

[0019] In a possible implementation, the elastic ring has a second concave annular groove on its inner circumferential wall, and the outer circumferential wall of the outer sleeve has a second convex annular portion embedded in the second concave annular groove.

[0020] In a possible implementation, the elastic ring includes:

[0021] Two elastic plates are respectively arranged on both sides of the heat insulation plate and abut against the outer side surface of the heat insulation plate; two through holes are respectively opened on the two elastic plates and are connected to each other, and the through holes are connected to the mounting hole;

[0022] Wherein, the positioning sleeve is inserted into the through hole, and the outer peripheral wall of the positioning sleeve is connected to the inner peripheral wall of the through hole.

[0023] In a possible implementation, the elastic ring further includes:

[0024] Two filling rings are fixedly arranged on adjacent sides of the two elastic plates, and the two filling rings abut against each other; the two filling rings are both embedded in the mounting hole and are suitable for filling the gap between the inner peripheral wall of the mounting hole and the outer peripheral wall of the positioning sleeve.

[0025] In a possible implementation, adjacent side surfaces of the two filling rings are respectively provided with a magnet component and a ferromagnetic component capable of generating a magnetic attraction effect.

[0026] In a possible implementation, the elastic ring is made of steel wool.

[0027] In the embodiment of the present application, when shear force is generated at the edge of the limiting end and acts on the positioning sleeve, since there is an elastic ring between the positioning sleeve and the mounting hole, the elastic action of the elastic ring can effectively absorb the aforementioned shear force, thereby reducing the damage to the insulation board caused by the shear force.

[0028] Compared with the prior art, the heat insulation board mounting structure provided in this embodiment can avoid the shear force generated between the flange surface of the mounting bolt and the contact edge of the heat insulation board, which can cause the heat insulation board to crack or break, thereby extending the service life of the heat insulation board, ensuring the heat insulation effect of the heat insulation board, and ensuring the safety of the vehicle during driving.

[0029] The technical solution adopted in the present application also provides an automobile, comprising the heat insulation board mounting structure proposed in any one of the aforementioned items.

[0038] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application more clearly understood, this application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0039] It should be noted that when an element is referred to as being “fixed on” or “disposed on” another element, it may be directly on the other element or indirectly on the other element. When an element is referred to as being “connected to” another element, it may be directly connected to the other element or indirectly connected to the other element.

[0040] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0041] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0042] Please also refer to Figures 1 to 5 The heat insulation board installation structure provided by the present application is now described. The heat insulation board installation structure proposed in the present application includes a mounting hole 1, a mounting bolt 2, a positioning sleeve 3 and an elastic ring 4.

[0043] The mounting hole 1 is provided on the heat insulation board, specifically, at a position where the heat insulation board and the mounting surface coincide with each other.

[0044] The mounting bolt 2 is inserted into the mounting hole 1 and is threadedly connected to the mounting surface. Specifically, a threaded hole or threaded groove that can be threadedly connected to the mounting bolt 2 is provided on the mounting surface to achieve the connection between the mounting bolt 2 and the mounting surface.

[0045] Furthermore, the mounting bolt 2 also has a limiting end 21 adapted to abut against the heat insulation board. During the driving of the vehicle, the vibration of the heat insulation board will cause the limiting end 21 to transmit shear force to the components in contact therewith.

[0046] The positioning sleeve 3 is sleeved on the outer periphery of the mounting bolt 2 and is made of a hard material. After assembly, one end of the positioning sleeve 3 abuts against the limiting end 21 to transfer the stress generated by the aforementioned shear force.

[0047] The elastic ring 4 is sleeved on the outer periphery of the positioning sleeve 3 and is embedded in the mounting hole 1 to absorb stress.

[0048] In the embodiment of the present application, when a shear force is generated at the edge of the limiting end 21 and acts on the positioning sleeve 3, since there is an elastic ring 4 between the positioning sleeve 3 and the mounting hole 1, the elastic action of the elastic ring 4 can effectively absorb the aforementioned shear force, thereby reducing the damage to the insulation board caused by the shear force.

[0049] Compared with the prior art, the heat insulation board mounting structure provided in this embodiment can avoid the shear force generated between the flange surface of the mounting bolt 2 and the contact edge of the heat insulation board, which can cause the heat insulation board to crack or break, thereby extending the service life of the heat insulation board, ensuring the heat insulation effect of the heat insulation board, and ensuring the safety of the vehicle during driving.

[0050] In some embodiments, as Figure 3 and Figure 4 As shown, the positioning sleeve 3 includes an inner sleeve 31 and an outer sleeve 32 .

[0051] The inner sleeve 31 is sleeved on the outer periphery of the mounting bolt 2; it should be noted that, in some embodiments, there is a gap between the outer peripheral wall of the mounting bolt 2 and the inner peripheral wall of the positioning sleeve 3 to prevent the rod of the mounting bolt 2 from transmitting stress to the positioning sleeve 3.

[0052] The outer sleeve 32 is sleeved on the outer circumference of the inner sleeve 31 , and the elastic ring 4 is sleeved on the outer circumference of the outer sleeve 32 .

[0053] Among them, the inner circumferential wall of the outer sleeve 32 has a first concave annular groove 321, and the outer circumferential wall of the inner sleeve 31 has a first convex ring portion 311 embedded in the first concave annular groove 321 to achieve the clamping of the outer sleeve 32 and the inner sleeve 31 and limit the relative movement of the outer sleeve 32 and the inner sleeve 31.

[0054] By adopting the above technical solution, the inner sleeve 31 and the outer sleeve 32 can be separated from each other, so as to facilitate the installation and removal of the positioning sleeve 3 between the elastic ring 4 and the mounting bolt 2.

[0055] In some embodiments, as Figure 4 As shown, the inner sleeve 31 has a first limiting ring 312 extending radially outward, and the outer sleeve 32 has a second limiting ring 322 extending radially outward.

[0056] By adopting the above technical solution, when the elastic ring 4 is placed on the outer periphery of the outer sleeve 32 and the first convex ring portion 311 is embedded in the first concave ring groove 321, the first limiting ring 312 and the second limiting ring 322 respectively abut against the two ends of the elastic ring 4 to limit the movement of the elastic ring 4 relative to the positioning sleeve 3.

[0057] In some embodiments, for the sake of convenience, the side of the elastic ring 4 that is connected to the first limiting ring 312 is defined as the first side of the elastic ring 4, and the side of the elastic ring 4 that is connected to the second limiting ring 322 is defined as the second side of the elastic ring 4. Figure 3 and Figure 4 As shown, the distance between the second surface of the elastic ring 4 and the contact surface between the first limiting ring 312 and the elastic ring 4 is greater than the length of the outer sleeve 32, so that when the first convex ring portion 311 is embedded in the first concave ring groove 321, a reserved gap can be formed between the outer sleeve 32 and the first limiting ring 312.

[0058] Moreover, when the first convex ring portion 311 is embedded in the first concave ring groove 321 and the elastic ring 4 is placed on the outer periphery of the outer sleeve 32, the elastic ring 4 is suitable for elastic deformation and embedding into the aforementioned reserved gap, thereby preventing the structure from loosening and improving the structural stability and strength.

[0059] In some embodiments, as Figure 3 and Figure 4 As shown, the inner peripheral wall of the elastic ring 4 has a second concave annular groove 412 , and the outer peripheral wall of the outer sleeve 32 has a second convex annular portion 323 embedded in the second concave annular groove 412 .

[0060] By adopting the above technical solution, the structural strength of the elastic ring 4 relative to the outer sleeve 32 can be enhanced through the clamping relationship between the second convex ring portion 323 and the second concave ring groove 412.

[0061] In some embodiments, as Figures 3 to 5 As shown, the elastic ring 4 includes two elastic plates 41 .

[0062] Two elastic plates 41 are disposed on either side of the insulation board, abutting the outer sides of the insulation board. Each elastic plate 41 is provided with a through hole 411 extending through the thickness thereof. The two through holes 411 corresponding to the two elastic plates 41 are interconnected, and each through hole 411 can communicate with the mounting hole 1.

[0063] After actual assembly, the positioning sleeve 3 is inserted into the through hole 411 , and the outer peripheral wall of the positioning sleeve 3 is connected to the inner peripheral wall of the through hole 411 .

[0064] It should be noted that the aperture of the through hole 411 is usually smaller than the aperture of the mounting hole 1, so that a gap extending along the axial direction of the mounting hole 1 is formed between the elastic plate 41 and the mounting hole 1; in order to fill this gap, in some embodiments, such as Figures 3 to 5 As shown, the elastic ring 4 further includes two filling rings 42 .

[0065] The two filling rings 42 are fixedly arranged on adjacent sides of the two elastic plates 41, and the two filling rings 42 abut against each other; wherein, the two filling rings 42 are both embedded in the mounting hole 1 and are suitable for filling the gap between the inner peripheral wall of the mounting hole 1 and the outer peripheral wall of the positioning sleeve 3 (that is, the aforementioned gap extending axially along the mounting hole 1).

[0066] By adopting the above technical solution, the filling ring 42 plays a role of filling the gap, thereby improving the stability of the combined structure of the filling ring 42 and the positioning sleeve 3.

[0067] In some embodiments, magnets and ferromagnetic parts capable of producing a magnetic attraction effect are respectively provided on adjacent sides of the two filling rings 42, so that when the two filling rings 42 are connected, the magnets and ferromagnetic parts attract each other, preventing the two filling rings 42 from being separated by slight shaking or external force.

[0068] In some embodiments, the elastic ring 4 is made of steel wool; wherein steel wool is also called steel wool or steel wool, and the material is velvet-like and consists of multiple continuous fibers.

[0069] By adopting the above technical solution, the elastic ring 4 made of steel wool can absorb stress to prevent the positioning sleeve 3 from applying the shear force generated by the limiting end 21 to the insulation board.

[0070] In some embodiments, the mounting hole 1 is a circular hole, an elliptical hole, an oblong hole, or a square hole; accordingly, the positioning sleeve 3 and the elastic ring 4 both adopt a structure matching the mounting hole 1 .

[0071] In this embodiment, the mounting hole 1 is a circular hole, and the corresponding positioning sleeve 3 and elastic ring 4 both have a circular cross-section.

[0072] Based on the same inventive concept, an embodiment of the present application also provides an automobile, comprising the heat insulation board mounting structure proposed in any of the aforementioned items.

[0073] The beneficial effects of the automobile provided by this embodiment are the same as those of the aforementioned heat insulation board mounting structure, and will not be repeated here.

[0074] The above content is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
