Description

Technical Field

[0001] The present invention relates to automotive parts, and particularly to a heat insulation plate assembly that can be assembled and fixed in multiple dimensions. Background Art

[0002] As a component for isolating heat sources from surrounding structures, heat insulation plates are widely used in various working conditions of automobiles. Generally, lightweight aluminum foil is selected and processed by forming methods, which have the characteristics of simple structure, light weight, and low price. Currently, the heat insulation plate structures adopted in the market mainly include U-shaped structures, straight-shaped structures, combined structures, etc. U-shaped and straight-shaped heat insulation plates are generally used for heat insulation in the exhaust pipe area, with a large heat insulation area and good effects. The installation points of U-shaped and straight-shaped heat insulation plates are generally arranged in areas such as flange surfaces and U-shaped bottom surfaces, and the assembly method is relatively convenient. However, the installation points are basically arranged on a plane in the same direction, and only a single direction (such as the Z direction) can be used for fixing during the assembly process, and a multi-dimensional fixing method cannot be achieved, resulting in inflexible assembly and the inability to achieve heat insulation in multiple directions. The combined heat insulation plate is generally composed of a heat insulation plate with a main structure and several installation brackets riveted and fixed by rivets, and can be assembled by a multi-dimensional fixing method, with good heat insulation effects. However, it has more components, complex shapes, and higher manufacturing costs.

[0003] CN114135381A discloses a heat insulation plate, a heat insulation plate installation structure, and a vehicle. The heat insulation plate includes a heat insulation plate body. The left and right sides of the heat insulation plate body have installation parts, which are double-layer structures formed by flanging the edges of the heat insulation plate body. A diversion part is formed at the front of the heat insulation plate body for diverting the flowing gas to reduce the force of the gas on the outside of the heat insulation plate. This invention solves the problems that the existing heat insulation plate has poor reliability of installation points, resulting in cracking of the installation points, and insufficient strength, thereby causing the heat insulation plate to fall off. Undoubtedly, the technical solution disclosed in the above patent document is a beneficial attempt in the technical field, but there is still room for improvement in the assembly structure. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a heat insulation plate assembly that can be assembled and fixed in multiple dimensions, which can form heat insulation surfaces in multiple different directions, can meet the heat insulation requirements in multiple dimensions, and at the same time has a simple structure, low processing complexity, and low production cost.

[0005] An insulating panel assembly that can be assembled and fixed in multiple dimensions in the present invention includes an insulating longitudinal plate, a first insulating transverse plate, and a second insulating transverse plate; the upper part of the insulating longitudinal plate is connected to the rear part of the first insulating transverse plate, and the lower part of the insulating longitudinal plate is connected to the front part of the second insulating transverse plate; at least two positioning bosses are provided on the insulating longitudinal plate, and positioning holes penetrating in the front-rear direction are provided on the positioning bosses; the second insulating transverse plate includes an insulating transverse plate main body and an assembly boss protruding upward from the insulating transverse plate main body, the assembly boss includes a boss top wall and a boss side wall, and the upper and lower ends of the boss side wall are respectively connected to the boss top wall and the insulating transverse plate main body; an assembly through groove penetrating in the up-down direction is provided on the boss top wall, and a relief through groove penetrating in the front-rear direction and in the up-down direction is provided on the boss side wall, and the rear end of the assembly through groove is communicated with the front end of the relief through groove.

[0006] Further, the assembly boss has a structure that is smaller at the top and larger at the bottom.

[0007] Further, the front end of the assembly through groove extends to the middle of the boss top wall.

[0008] Further, the upper end surface of the boss top wall is perpendicular to the penetration direction of the assembly through groove; the positioning boss protrudes backward from the insulating longitudinal plate, and the axis of the positioning hole is perpendicular to the rear end surface of the positioning boss.

[0009] Further, a plurality of heat radiation reflection ribs are arranged at intervals in the left-right direction on the first insulating transverse plate, and the lengths of the plurality of heat radiation reflection ribs are arranged in the front-rear direction.

[0010] Further, the plurality of heat radiation reflection ribs all protrude downward from the first insulating transverse plate.

[0011] Further, a plurality of reinforcing ribs are distributed at intervals on the insulating transverse plate main body.

[0012] Further, a edge wrapping structure is provided at the front part of the first insulating transverse plate and the rear part of the second insulating transverse plate.

[0013] The beneficial effects of the present invention are:

[0014] 1. The present invention can form insulating surfaces in multiple different directions, can meet the insulating requirements in multiple dimensions, and at the same time has a simple structure, low processing complexity and production cost;

[0015] 2. During the assembly of the present invention, the heat insulation longitudinal plate and the second heat insulation transverse plate can be fixed separately. The positioning holes of the heat insulation longitudinal plate are in the front-back direction. Therefore, the first projection welding stud, the heat insulation longitudinal plate, and the snap fastener achieve the X-direction fixation of the heat insulation plate assembly. The special-shaped through groove formed by the connection and combination of the assembly through groove and the relief through groove can meet the avoidance requirement of the second projection welding stud in the X-direction while realizing the Z-direction fixation method. Therefore, the second projection welding stud, the second heat insulation transverse plate, and the thrust round nut can achieve the Z-direction fixation of the heat insulation plate assembly, and finally realize the assembly and fixation method of two planes in different directions of the heat insulation plate assembly, that is, realize the multi-dimensional assembly and fixation method;

[0016] 3. The heat insulation plate assembly of the present invention can share the projection welding nuts with the engine compartment sound insulation pad assembly, which can make the structure more compact and reduce the requirement for the assembly space. Before the final positioning, both the heat insulation plate assembly and the engine compartment sound insulation pad assembly are pre-hung on the heater plenum panel assembly, which can reduce the assembly difficulty, reduce the assembly workload, and improve the assembly efficiency. When performing the final positioning, only the snap fastener and the thrust round nut need to be installed, which is convenient for operation in a narrow space;

[0017] 4. On the one hand, the heat radiation reflection ribs of the present invention can increase the heat insulation area of the first heat insulation transverse plate and strengthen the heat radiation diversion and reflection ability. On the other hand, there is no positioning structure on the first heat insulation transverse plate, which is in a cantilever structure. The heat radiation reflection ribs can also strengthen the local structure and prevent the first heat insulation transverse plate from generating jitter and abnormal noise during the vehicle's driving due to the cantilever structure.

Detailed implementation manners

[0028] The technical solutions of the present invention will be described in detail below with reference to the attached drawings and embodiments.

[0029] As Figures 1-6 shown, a heat insulation plate assembly 100 that can be assembled and fixed in multiple dimensions in this embodiment includes a heat insulation longitudinal plate 110, a first heat insulation transverse plate 120, and a second heat insulation transverse plate 130; the upper part of the heat insulation longitudinal plate 110 is connected to the rear part of the first heat insulation transverse plate 120, and the lower part of the heat insulation longitudinal plate 110 is connected to the front part of the second heat insulation transverse plate 130; at least two positioning bosses 111 are provided on the heat insulation longitudinal plate 110, and positioning holes 112 penetrating in the front-rear direction are provided on the positioning bosses 111; the second heat insulation transverse plate 130 includes a heat insulation transverse plate main body and an assembly boss 140 protruding upward from the heat insulation transverse plate main body, the assembly boss 140 includes a boss top wall 141 and a boss side wall 142, and the upper and lower ends of the boss side wall 142 are respectively connected to the boss top wall 141 and the heat insulation transverse plate main body; an assembly through slot 143 penetrating in the up-down direction is provided on the boss top wall 141, and a relief through slot 144 penetrating in the front-rear direction and in the up-down direction is provided on the boss side wall 142, and the rear end of the assembly through slot 143 is communicated with the front end of the relief through slot 144.

[0030] In this embodiment, the number of the positioning bosses 111 is two, and each of the two positioning bosses 111 is provided with a positioning hole 112; during assembly, first, two first projection welding studs 201 and one second projection welding stud 202 are provided on the heater plenum panel assembly 200 of the vehicle by welding. The axes of the two first projection welding studs 201 are in the front-rear direction, and the axis of the second projection welding stud 202 is in the up-down direction. Then, the engine compartment sound insulation pad assembly 300 is pre-hung on the two first projection welding studs 201. The engine compartment sound insulation pad assembly 300 is provided with stud through holes 301 corresponding to the positions of the first projection welding studs 201, and a relief opening groove 302 is provided at the position corresponding to the second projection welding stud 202. The relief opening groove 302 exposes the peripheral position of the heater plenum panel assembly 200 corresponding to the second projection welding stud 202; then, the multi-dimensionally assembled and fixed heat insulation plate assembly 100 is moved along the front-to-back assembly direction. During the movement, the positions of the two positioning holes 112 respectively correspond to the positions of the two first projection welding studs 201, and the position of the relief through groove 144 corresponds to the position of the second projection welding stud 202. When the two first projection welding studs 201 are respectively inserted into the two positioning holes 112 and the heat insulation plate assembly 100 is continuously moved along the front-to-back assembly direction, the second projection welding stud 202 gradually passes through the relief through groove 144 and enters the assembly through groove 143. At this time, the cooperation between the two positioning holes 112 and the two first projection welding studs 201 causes the heat insulation plate assembly 100 to be pre-hung on the two first projection welding studs 201 as well. Finally, the heat insulation plate assembly 100 is fixed by connecting the two snap fasteners 400 or nuts to the two first projection welding studs 201 respectively, and connecting the thrust round nut 500 to the second projection welding stud 202. Correspondingly, the engine compartment sound insulation pad assembly 300 is also fixed between the heat insulation plate assembly 100 and the heater plenum panel assembly 200. At this time, the positioning bosses 111 abut against the engine compartment sound insulation pad assembly 300, and the assembly bosses 140 abut against the peripheral position of the second projection welding stud 202 of the heater plenum panel assembly 200.

[0031] The heat insulation longitudinal plate 110, the first heat insulation transverse plate 120 and the second heat insulation transverse plate 130 form an integral body. The first heat insulation transverse plate 120 extends forward from the upper part of the heat insulation longitudinal plate 110, and the second heat insulation transverse plate 130 extends backward from the lower part of the heat insulation longitudinal plate 110, which can form heat insulation surfaces in multiple different directions, meet the heat insulation requirements in multiple dimensions, and at the same time have a simple structure, low processing complexity and low production cost. In addition, multi-dimensional assembly and fixation means respectively assembling and fixing planes in multiple different directions. During assembly, the heat insulation longitudinal plate 110 and the second heat insulation transverse plate 130 can be fixed respectively. The positioning hole 112 of the heat insulation longitudinal plate 110 is in the front-back direction. Therefore, the first projection welding stud 201, the heat insulation longitudinal plate 110 and the snap fastener 400 realize the X-direction fixation of the heat insulation plate assembly 100. The special-shaped through groove formed by the communication combination of the assembly through groove 143 and the relief through groove 144 can meet the avoidance requirement of the second projection welding stud 202 in the X-direction while realizing the fixation method in the Z-direction. Therefore, the second projection welding stud 202, the second heat insulation transverse plate 130 and the thrust round nut 500 can realize the Z-direction fixation of the heat insulation plate assembly 100, and finally realize the assembly and fixation methods of two planes in different directions of the heat insulation plate assembly 100, that is, realize the multi-dimensional assembly and fixation method. And because the heat insulation plate assembly 100 can share the projection welding nuts with the engine compartment sound insulation pad assembly 300, the structure can be made more compact and the assembly space requirement can be reduced. Before the final positioning, both the heat insulation plate assembly 100 and the engine compartment sound insulation pad assembly 300 are pre-hung on the heater plenum panel assembly 200, which can reduce the assembly difficulty, reduce the assembly workload and improve the assembly efficiency. During the final positioning, only the snap fastener and the thrust round nut need to be installed, which is convenient for operation in a narrow space. It should be noted that the X-direction is the front-back direction of the vehicle, and the Z-direction is the up-down direction of the vehicle.

[0032] In this embodiment, the assembly boss 140 has a structure with a smaller upper part and a larger lower part, which is convenient for processing and forming.

[0033] In this embodiment, the front end of the assembly through groove 143 extends to the middle of the top wall 141 of the boss. The top wall 141 of the boss is fixed between the thrust round nut 500 and the heater plenum panel assembly 200. The extension of the front end of the assembly through groove 143 to the middle of the top wall 141 of the boss can make the thrust round nut 500 act on the middle of the top wall 141 of the boss to ensure the fixing effect.

[0034] In this embodiment, the upper end surface of the convex platform top wall 141 is perpendicular to the through direction of the assembly through groove 143; the positioning convex platform 111 protrudes backward from the heat insulation longitudinal plate 110, and the axis of the positioning hole 112 is perpendicular to the rear end surface of the positioning convex platform 111. The upper end surface of the convex platform top wall 141 and the rear end surface of the positioning convex platform 111 are located on different planes. The rear end surface of the positioning convex platform 111 abuts against the engine compartment sound insulation pad assembly 300, and the upper end surface of the convex platform top wall 141 of the assembly convex platform 140 abuts against the peripheral position of the second projection welding stud 202 of the heater pressure chamber plate assembly 200.

[0035] In this embodiment, a plurality of heat radiation reflection ribs 121 are arranged at intervals in the left - right direction on the first heat insulation transverse plate 120, and the lengths of the plurality of heat radiation reflection ribs 121 are arranged in the front - rear direction. On the one hand, the heat radiation reflection ribs 121 can increase the heat insulation area of the first heat insulation transverse plate 120 and strengthen the heat radiation diversion and reflection ability. On the other hand, there is no positioning structure on the first heat insulation transverse plate 120, and it is in a cantilever structure. The heat radiation reflection ribs 121 can also strengthen the local structure and prevent the first heat insulation transverse plate 120 from generating jitter and abnormal noise during the vehicle's driving process due to the cantilever structure.

[0036] In this embodiment, a plurality of the heat radiation reflection ribs 121 all protrude downward from the first heat insulation transverse plate 120.

[0037] In this embodiment, a plurality of reinforcing ribs 131 are distributed at intervals on the heat insulation transverse plate main body, and the main function of the reinforcing ribs 131 is to increase the strength of the heat insulation transverse plate main body.

[0038] In this embodiment, edge - wrapping structures 150 are arranged at the front part of the first heat insulation transverse plate 120 and the rear part of the second heat insulation transverse plate 130. The edge - wrapping structures 150 can reduce the risk of personnel scratching during the assembly process, and can also greatly reduce the quality risk and part cost during the forming process.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
