The cover plate 1000 is a metal structure, fig. 3 shows a schematic structural diagram of the cover plate 1000, and in combination with fig. 3 and fig. 2, a heat dissipating boss 1010 is disposed on a surface of the cover plate 1000 facing the intermediate member 3000, and a gap is formed between the heat dissipating boss 1010 and the intermediate member 3000. Referring back to fig. 2, the heat dissipating device 100 further includes a heat dissipating glue 4000, and the heat dissipating glue 4000 fills the gap. The intermediate member 3000 is provided with a pin 5000. In this embodiment, the middleware 3000 includes, but is not limited to, a PCBA board. The heat dissipation glue 4000 is in contact with the intermediate member 3000 and the heat dissipation boss 1010, so that heat generated by the intermediate member 3000 can be transferred to the cover plate 1000 via the heat dissipation glue 4000 and then dissipated by the cover plate 1000, thereby realizing a heat dissipation effect. The cover plate 1000 is made of metal, so that the cover plate has good heat conduction and heat dissipation effects. The material of the cover plate 1000 includes, but is not limited to, aluminum alloy, which has the advantages of light weight and good heat dissipation effect.

In this embodiment, the cover 1000 includes a first bottom plate 1100, and the heat dissipating boss 1010 is disposed on the first bottom plate 1100. The cover 1000 is a stamping part, so as to facilitate controlling the size of the first bottom plate 1100, and further facilitate assembly, preferably the first bottom plate 1100 includes a plate body 1110 and a transition portion 1120, the transition portion 1120 is connected to an edge of the plate body 1110, the transition portion 1120 protrudes from the plate body 1110 in a direction toward the intermediate member 3000, and at least a partial area of the transition portion 1120 is formed into a curved structure.

The specific shape of the transition portion 1120 is not particularly limited in this embodiment, for example, in one non-limiting implementation, as shown in fig. 6, the transition portion 1120 includes a first sub-transition portion 1121 and a second sub-transition portion 1122, the first sub-transition portion 1121 is connected with the plate body 1110, and a cross section of the first sub-transition portion 1121 perpendicular to the plate body 1110 is substantially S-shaped. The second sub-transition portion 1122 is connected to the first sub-transition portion 1121, at least a portion of the second sub-transition portion 1122 has a planar structure, and the planar structure is parallel to the plate 1110. Alternatively, in another implementation, as shown in fig. 8, the transition 1120 includes a first sub-transition 1121, a second sub-transition 1122, a third sub-transition 1123, and a fourth sub-transition 1124 that are sequentially connected. The first sub-transition portion 1121 is connected to the plate body 1110, and a cross section of the first sub-transition portion 1121 perpendicular to the plate body 1110 is substantially S-shaped. The second sub-transition 1122 has a planar structure, and the second sub-transition 1122 is parallel to the plate 1110. The third sub-transition portion 1123 has a curved surface structure, a cross section of the third sub-transition portion 1123 perpendicular to the plate body 1110 is arc-shaped, and a concave side of the arc-shaped is toward the inside of the heat dissipating device 100. The fourth sub-transition 1124 is a planar structure and is perpendicular to the plate 1110. In this implementation, a portion of the inner surface of the third sub-transition 1123 abuts a portion of the outer surface of the baffle wall 2200. Still alternatively, as shown in fig. 9, the transition portion 1120 includes a first sub-transition portion 1121 and a second sub-transition portion 1122, the first sub-transition portion 1121 is connected to the board body 1110, at least a part of a region of the first sub-transition portion 1121 is of a curved surface structure, a cross section of the region of the first sub-transition portion 1121 having the curved surface structure perpendicular to the board body 1110 is of an arc shape, and a concave side of the arc shape faces the inside of the heat dissipating device 100. The second sub-transition 1122 is connected to the first sub-transition 1121, and the second sub-transition 1122 extends in a direction toward the intermediate member 3000.

Alternatively, as shown in fig. 2, the housing 2000, the cover 1000, and the intermediate member 3000 are connected by screws 6000. Furthermore, the housing 2000 is also connected to the cover plate 1000 by a snap-fit connection. This reduces the number of screws on the one hand, and thus the area of the intermediate member 3000 occupied by the screws, and on the other hand, improves the reliability of the connection between the housing 2000, the cover 1000, and the intermediate member 3000.

Referring to fig. 2, 3 and fig. 4 to 6, the cover 1000 further includes a first clamping member 1200, and the first clamping member 1200 is connected to the first bottom plate 1100, specifically, the transition portion 1120, and extends along a direction toward the housing 2000. The housing 2000 includes a second base plate 2100 and a blocking wall 2200 provided on the second base plate 2100 and extending in a direction toward the cover plate 1000. The outer surface of the baffle wall 2200 is provided with a second clamping piece 2300, and the second clamping piece 2300 is clamped with the first clamping piece 1200.

In more detail, the first clamping member 1200 extends along a direction toward the second base plate 2100, and a clamping interface 1210 is provided on the first clamping member 1200. The second catching member 2300 includes an engaging portion 2310 and a catching portion 2320, the engaging portion 2310 having opposite first and second ends in a direction perpendicular to the second base plate 2100, the first end being connected to the blocking wall 2200. The engagement portion 2310 is configured to have elasticity such that the second end can move to approach or separate from the blocking wall 2200 when the engagement portion 2310 is forced. In this embodiment, the force applied to the engaging portion 2310 is an external force or a force generated by itself. The engaging portion 2320 is disposed at a second end of the engaging portion 2310, and the engaging portion 2320 is inserted into the card interface 1210. The structure of the second clamping member 2300 can reduce the assembling force, and is convenient to assemble and disassemble.

Alternatively, the engagement portion 2310 includes an engagement arm 2311 and an engagement block 2312, the engagement arm 2311 extends in a direction perpendicular to the second base plate 2100, the engagement block 2312 is connected to one end of the engagement arm 2311, and the engagement block 2312 is connected to the blocking wall 2200 such that the engagement arm 2311 does not contact with the blocking wall 2200, i.e., the engagement block 2312 constitutes the first end of the engagement portion 2310, and an end of the engagement arm 2311 remote from the engagement block 2312 constitutes the second end of the engagement portion 2310. In practice, the housing 2000 is entirely made of plastic, in other words, the engaging portion 2310 is made of plastic, and the engaging portion 2310 has a certain elasticity due to the certain elasticity of the plastic. Taking the orientation of fig. 6 as an example, when the engaging arm 2311 is pressed from left to right, the second end of the engaging portion 2310 moves rightward to approach the blocking wall 2200, and the engaging portion 2320 approaches the blocking wall 2200 along with the second end of the engaging portion 2310, that is, the engaging portion 2320 is disengaged from the engaging portion 1210. The engagement arm 2311 also stores elastic potential energy during this process. When the pressing force is removed, the engagement arm 2311 releases elastic potential energy, so that the second end of the engagement portion 2310 moves leftwards under the elastic potential energy (i.e., the elastic force of the engagement arm 2311), and thus the catching portion 1230 moves leftwards and is inserted into the catching interface 1210.

Further, the outer surface of the blocking wall 2200 is further provided with clamping structures, and the number of the clamping structures is the same as that of the second clamping pieces 2300. Each of the clamping structures includes two clips 2410, two of the clips 2410 are arranged in a direction parallel to the second base plate 2100, and two of the clips 2410 are located at opposite sides of one of the second clamping members 2300. When the first clamping member 1200 is clamped with the second clamping member 2300, the clamping piece 2410 is pressed against the outer surface of the first clamping member 1200. By the arrangement of the clamping structure, the clamping piece 2410 can be utilized to limit the first clamping piece 1200 in the direction perpendicular to the blocking wall 2200, so that the second clamping piece 2300 is prevented from being separated from the first clamping piece 1200 due to the error touch of the second clamping piece 2300, and the connection reliability of the housing 2000 and the cover plate 1000 is improved.

Optionally, referring to fig. 3, 6 and 7, the heat dissipating device 100 further includes a plurality of pressing boss assemblies 7000, and each pressing boss assembly 7000 includes a first pressing boss 7100 and a second pressing boss 7200. The first pressing boss 7100 is disposed on the cover plate 1000, specifically, the first bottom plate 1100, and the first pressing boss 7100 presses against a surface of the intermediate member 3000 facing the first bottom plate 1100. The second pressing boss 7200 is disposed on the housing 2000, specifically, the second base plate 2100, and the second pressing boss 7200 presses against a surface of the intermediate member 3000 facing the second base plate 2100. Those skilled in the art will know that the second base plate 2100 of the housing 2000 is provided with a plugging channel (not labeled in the drawing) corresponding to the pin 5000, where the pin 5000 is used to plug with an external connector at the plugging channel, and in this embodiment, the pressing boss component 7000 presses against the intermediate piece 3000, so that the intermediate piece 3000 can be limited in a direction perpendicular to the first base plate 1100, and then, when the external connector is plugged and unplugged, the position of the intermediate piece 3000 can be kept fixed, so that the probability of occurrence of pin withdrawal can be reduced.

Preferably, referring to fig. 7, each of the pressing boss assemblies 7000 includes one first pressing boss 7100 and two second pressing bosses 7200. In the same pressing boss assembly 7000, the two second pressing bosses 7200 are located on opposite sides of the first pressing boss 7100, which has the advantage of reducing alignment accuracy of the housing 2000, the cover 1000, and the intermediate member 3000 during assembly, and facilitating assembly.

Referring back to fig. 3, for a portion of the pressing boss assembly 7000, the first pressing boss 7100 is disposed on the plate body 1110 of the first base plate 1100, and for another portion of the pressing boss assembly 7000, the first pressing boss 7100 is disposed on the transition portion 1120 of the first base plate 1100. The shape of the first pressing boss 7100 is not particularly limited in this embodiment, and in some embodiments, a cross section of the first pressing boss 7100 parallel to a plane of the first base plate 1100 is circular or rectangular or any other suitable shape. Further, the first pressing boss 7100 provided on the transition portion 1120 may be provided at any suitable position of the transition portion 1120. For example, in the heat dissipating device 100 shown in fig. 6, the first pressing boss 7100 is formed on the second sub-transition 1122. Alternatively, in the heat dissipating device 100 shown in fig. 9 and 10, the first pressing boss 7100 is provided at the intersection of the first sub-transition portion 1121 and the second sub-transition portion 1122, the first pressing boss 7100 is substantially L-shaped, and one inner surface of the first pressing boss 7100 is parallel to the bottom plate 1110 and is used for pressing against the intermediate member 3000. In addition, the first pressing boss 7100 may be integrally formed with the first base plate 1100, and as described above, the cover plate 1000 is a stamping part, so that the first base plate 1100 and the first pressing boss 7100 may be formed by one-step stamping using the same plate.

It will be appreciated by those skilled in the art that the heat sink 100 may be applied to a controller, and thus embodiments of the present utility model also provide a controller including the aforementioned heat sink 100, including but not limited to an automotive domain controller.

Further, the embodiment of the utility model also provides an automobile, which comprises the controller.
