DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The ERG cooler quick disassembly device provided by the embodiment of the utility model is described in detail below in conjunction with the accompanying drawings.

[0023] Reference Figure 1 to Figure 6 The ERG cooler quick disassembly device provided in the embodiment of the utility model includes a first pressure plate 10 and a second pressure plate 20; the first pressure plate 10 is fixed on the engine cylinder head, the first pressure plate 10 includes a first main board 11 and a first connecting portion 12 and a first clamping portion 13 connected to both ends of the first main board 11, the second pressure plate 20 includes a second main board 21 and a second connecting portion 22 and a second clamping portion 23 connected to both ends of the second main board 21, the first connecting portion 12 is rotatably connected to the second connecting portion 22, and the second clamping portion 23 is clamped to the first clamping portion 13; there is a gap between the first main board 11 and the second main board 21, and the gap is used to accommodate the ERG cooler 30.

[0024] The ERG cooler quick disassembly device in the present application is characterized in that the first main board 11 is detachably mounted on the engine cylinder head, the second main board 21 is rotatably connected to the first connecting part 12 through the second connecting part 22, and the second main board 21 is clamped to the first clamping part 13 through the second clamping part 23, so that the second main board 21 is clamped to the first main board 11. There is a gap between the first main board 11 and the second main board 21, and the gap is used to accommodate the ERG cooler. When the ERG cooler needs to be disassembled and replaced from the engine cylinder head, it is sufficient to disengage the second clamping part 23 from the first clamping part 13. Similarly, when the ERG cooler 30 is installed on the cylinder head of the engine, the second main board 21 is rotated so that the second clamping part 23 is clamped to the first clamping part 13. The process of installing and disassembling the ERG cooler 30 on the engine is simplified, and the difficulty of installing and disassembling the ERG cooler and the maintenance cost of the EGR cooler 30 are reduced.

[0025] It should be noted that the first main board 11 includes at least two connection holes 110, and the two connection holes 110 are used to fix the first main board 11 to the engine cylinder head. Specifically, the connecting member passes through the connection holes 110 to detachably fix the first main board 11 to the engine cylinder head.

[0026] In one embodiment, the first connecting portion 12 includes two connecting plates, the two connecting plates are a first connecting plate 120 and a second connecting plate 121, and the first connecting plate 120 and the second connecting plate 121 are arranged at intervals. The first connecting plate 120 includes at least one first mounting hole 122, and the second connecting plate 121 includes at least one second mounting hole 123, and the at least one first mounting hole 122 and the at least one second mounting hole 123 are symmetrically arranged. The rotating shaft is installed in a corresponding first mounting hole 122 and a first second mounting hole 123, and the rotating shaft can rotate relative to the first mounting hole 122 and the second mounting hole 123. The second connecting portion 22 includes a transfer groove 220, and the rotating shaft can pass through the transfer groove 220 and be rotatably connected to the transfer groove 220, so that the second connecting portion 22 is rotatably connected to the first connecting portion 12.

[0027] It is worth mentioning that when there are multiple first mounting holes 122 and multiple second mounting holes 123, the multiple first mounting holes 122 extend along the height direction of the first connecting plate 120, and the multiple second mounting holes 123 extend along the height direction of the second connecting plate 121. It can be understood that the first connecting plate 120 and the second connecting plate 121 have the same structure.

[0028] In one embodiment, the first clip 13 includes a first clip 130, a second clip 131, a third connecting plate 132 and a fourth connecting plate 134. The third connecting plate 132 and the fourth connecting plate 134 are arranged at intervals on a side of the first main board 11 away from the first connecting plate 120 and the second connecting plate 121. The first clip 130 is installed on a side of the third connecting plate 132 away from the first main board 11, and the second clip 131 is installed on a side of the fourth connecting plate 134 away from the first main board 11. The first clip 130 and the second clip 131 are arranged at intervals, and the clips of the first clip 130 and the second clip 131 are opposite, so as to facilitate the second clip 23 to be clipped with the first clip 13.

[0029] The second clamping portion 23 includes a first positioning plate 230 and a second positioning plate 231. The first positioning plate 230 and the second positioning plate 231 are arranged on a side of the second main board 21 away from the adapter slot 220, and the opening of the adapter slot 220 is located on the same side of the second main board 21 as the first positioning plate 230 and the second positioning plate 231. The first positioning plate 230 includes at least one first positioning hole 232, and the second positioning plate 231 includes at least one second positioning hole 233. The first positioning hole 232 is used to clamp with the first buckle 130, and the second positioning hole 233 is used to clamp with the second positioning hole 233, so that the second clamping portion 23 is clamped with the first clamping portion 13. Among them, the distance between the first positioning plate 230 and the second positioning plate 231 is smaller than the distance between the opposite sides of the first clip 130 and the second clip 131, so as to ensure the stability of the clamping between the second clamping part 23 and the first clamping part 13 after the first positioning plate 230 and the first clip 130 are matched and the second positioning plate 231 and the second clip 131 are matched.

[0030] In the above embodiment, the second main board 21 includes a groove 210, and the groove 210 is used to accommodate the ERG cooler. The above-mentioned gap is formed between the groove 210 and the first main board 11. When the first pressing plate 10 and the second pressing plate 20 are first engaged, the first main board 11, the second main board 21 and the groove 210 limit the movement of the ERG cooler 30 and fix the ERG cooler 30.

[0031] Obviously, those skilled in the art can make various changes and modifications to the embodiments of the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
