In addition, examples of various specific processes and materials are provided herein, but one of ordinary skill in the art may recognize applications of other processes and/or use of other materials.

The application is described below with reference to specific embodiments in conjunction with the following drawings:

in the related art, the heat sink 200 is mounted on the circuit board 100 by using "ear-limiting" manner on two sides, that is, after the "ear-clip" on one side of the heat sink 200 is first snapped into the clip of the circuit board 100, the heat sink 200 is grabbed to hook the clipped side, and the "ear-clip" on the other side of the heat sink 200 is pressed downwards to be snapped into the clip on the corresponding side of the circuit board 100. The installation and fixation mode of the radiator 200 has high requirements on the operation skills of workers, limits the investment of automation equipment and has low production efficiency.

In view of this problem, an embodiment of the present application proposes an electric control device, as shown in fig. 1 and 2, including:

a circuit board 100 provided with a clamping through hole 110;

a heat sink 200 disposed on the circuit board 100; and the number of the first and second groups,

the assembly connector 300 includes a support member 310 disposed on the heat sink 200 and an abutting member 320 disposed on the support member 310, the abutting member 320 having a deformation amount relative to the support member 310, the abutting member 320 being capable of passing through the detent through hole 110 after being deformed to dispose the heat sink 200 on the circuit board 100.

In the electric control device of the embodiment, the heat sink 200 is disposed on the circuit board 100 through the assembly connector 300, the support member 310 of the assembly connector 300 is vertically fixed on the heat sink 200, the abutting component 320 is disposed on the support member 310 and has a deformation amount vertical to the support member 310, that is, the abutting component 320 can deform in a direction parallel to the heat sink 200 or the circuit board 100, so when the assembly connector 300 is inserted into the retaining through hole 110, since the structure of the support member 310 remains unchanged, the support member 310 and the retaining through hole 110 can be accurately positioned, and thus, the accurate positioning can be performed by using an automated device; the abutting assembly 320 can deform in a direction parallel to the circuit board 100 to be squeezed and shortened when passing through the positioning through hole 110 so as to smoothly pass through the positioning through hole 110, and the abutting assembly 320 returns to the original shape after passing through the positioning through hole 110 and is engaged with the circuit board 100.

Further, the heat sink 200 is mounted on the circuit board 100 by using the "limit ears" on both sides, the order of silver mounting is uniform, the requirement for the dimensional accuracy of the "limit ears" of the heat sink 200 is high, and the dimensional deviation on any side can cause the heat sink 200 to be not tightly attached to the circuit board 100, and the reliability of the rigid heat sink 200.

In response to this problem, in the assembly connector 300 of the electronic control device of the present embodiment, since the structure of the supporting member 310 remains unchanged, during the process of connecting the heat sink 200 to the circuit board 100, the supporting member 310 can be used for accurate positioning, for example, the outer wall of the supporting member 310 passes through the card through-hole 110 along the edge of the card through-hole 110; meanwhile, since the clamping and abutting assembly 320 has a certain deformation, the deformation of the clamping and abutting assembly 320 can be utilized to reduce the distance between the clamping and abutting assembly 320 and the clamping and abutting through hole 110, so that the requirement on the processing precision of the assembly connector 300 is not high, and for example, the processing error of the assembly connection can be offset by the deformation of the clamping and abutting assembly 320.

Furthermore, in the electric control device of the present embodiment, no matter one assembly connector 300 is provided or more than two assembly connectors 300 are provided, the assembly connectors 300 can be directly and simultaneously inserted into the positioning through holes 110, so that the connection operation of the adapter connectors can be completed in one step without adopting two steps or a specific sequence, thereby reducing the assembly steps and improving the assembly efficiency.

In the present embodiment, the power module 130 is mounted as a chip on the circuit board 100, and after the heat sink 200 is mounted on the circuit board 100 via the mounting connector 300, the heat sink 200 and the power module 130 are closely attached to each other, thereby facilitating heat exchange between the heat sink 200 and the power module 130 and ensuring reliability of the heat sink 200.

As an alternative embodiment, as shown in fig. 2, the blocking and abutting assembly 320 of the present embodiment includes a blocking and abutting element 321 and a deformation element 322 having one end connected to the blocking and abutting element 321, and the other end of the deformation element 322 is further connected to the supporting element 310.

In order to make the blocking component 320 deform only in the direction parallel to the circuit board 100 (in the horizontal direction in the figure), in the blocking component 320 of the present embodiment, the blocking component 321 is used to block the blocking through hole 110, and the deformation component 322 is located between the blocking component 321 and the supporting component 310 to provide a horizontal deformation amount for the blocking component 320, so that the blocking component 321 deforms through the deformation component 322 after being blocked at the edge of the blocking through hole 110 to smoothly pass through the blocking through hole 110; after passing through the positioning through hole 110, the deformation member 322 recovers to eject the engaging member 321, so that the outer diameter of the assembly connector 300 is larger than the inner diameter of the positioning through hole 110, thereby fixing the heat sink 200 to the circuit board 100. And during the assembling process, it is avoided that the assembling connector 300 is deformed in the longitudinal direction to affect the smooth assembling.

In the related art, the buckle of the integrated structure needs to have both strength and elasticity of the buckle, so the buckle of the integrated structure needs a larger acting force when being assembled into the corresponding card slot/card hole, the acting force applied to the circuit board 100 is larger, and the circuit board 100 is easily damaged. In this embodiment, the elastic member is separately arranged to provide deformation in a direction parallel to the circuit board 100 for the engaging member 320, and the elastic member has a relatively large elasticity, so that when the assembling connector 300 is assembled into the engaging hole 110, a required acting force is relatively small, and damage to the circuit board 100 can be avoided.

Alternatively, in the present application, the deformation element 322 may be a spring, an elastic rubber, or other materials with certain elasticity. In the embodiment of the present application, a spring is used as the deformation member 322 to exemplify the electric control assembly of the present application.

As an alternative embodiment, as shown in fig. 1 and 2, the engaging member 321 has a slope surface that engages with the engaging through hole 110. In this embodiment, when the engaging member 320 passes through the engaging through hole 110, the slope of the engaging member 321 abuts against the engaging through hole 110 and compresses the deformation member 322 to deform the deformation member 322 so as to pass through the engaging through hole 110. As an alternative embodiment, as shown in fig. 1 and fig. 2, the abutting member 321 of the present embodiment is provided with an abutting portion 3211, and a longitudinal section of the abutting portion 3211 is an inverted trapezoid or an inverted triangle. In this embodiment, for example, when the assembly connector 300 is inserted into the card-positioning through hole 110 from above the circuit board 100, since the card-abutting portion 3211 is wide at the top and narrow at the bottom, and the cross section of the lower end of the assembly connector 300 is smaller than the card-positioning through hole 110, the whole lower end of the assembly connector 300 can enter the card-positioning through hole 110; with the insertion of the assembly connector 300, the engaging portion 3211 is wider and wider to engage with the engaging through hole 110, and at the same time, the deformation element 322 is compressed by the reaction force to deform and shorten the deformation element 322, so that the assembly connector 300 can smoothly pass through the engaging through hole 110; after the whole abutting assembly 320 of the assembly connector 300 passes through the positioning through hole 110, the abutting portion 3211 is no longer abutted against the abutting portion 3211, and the deformation element 322 loses the reaction force and recovers to its original shape, at this time, since the upper portion of the abutting portion 3211 is wide and the lower portion is narrow, the cross section of the upper end of the assembly connection is larger than the positioning through hole 110, the circuit board 100 is located between the heat sink 200 and the abutting assembly 320, and the purpose of disposing the heat sink 200 on the circuit board 100 is achieved.

As an optional embodiment, the abutting element 321 further has an abutting guide portion 3212 connected to the abutting portion 3211, and the abutting guide portion 3212 is sleeved outside the deformation element 322 or passes through a central axis of the deformation element 322. As shown in fig. 2, the blocking guide portion 3212 of the present embodiment is disposed in a spring as the deformation element 322, and the spring can only compress or spring in a direction defined by the blocking guide portion 3212, so that the blocking portion 3211 and the deformation element 322 can move in a horizontal direction defined by the blocking guide portion 3212, and the assembly connector 300 is prevented from being deformed in a longitudinal direction during the assembly process to affect the assembly.

In other embodiments, the abutting guide portion 3212 may also be a cylindrical structure and fit around the outside of the deformation element 322, so as to ensure that the abutting portion 3211 and the deformation element 322 move laterally under the restriction of the guiding element of the abutting portion 3211.

As an optional embodiment, the clamping and abutting assembly 320 further includes a deformation guiding element 323, and the deformation guiding element 323 is sleeved outside the deformation element 322 or passes through a central axis of the deformation element 322. As shown in fig. 2, the deforming guide 323 of the present embodiment has a cylindrical structure and is disposed outside the deforming guide 322. As shown in fig. 1, in a natural state, one end of the deformation guide 323 is fixed on the support member 310, and the other end of the deformation guide 323 is open to cover the outside of the elastic member, so that the deformation guide 322 can be ensured to move laterally under the limitation of the deformation guide 323.

Further preferably, as shown in fig. 2, the engaging and abutting assembly 320 of this embodiment is provided with a deformation guiding element 323, and the deformation guiding element 323 is sleeved outside the deformation element 322; meanwhile, the abutting part 321 is further provided with an abutting guide portion 3212 connected to the abutting portion 3211, the abutting guide portion 3212 penetrates the center of the deformation member 322 and is located in the central axis of the deformation guide member 323, so that the abutting guide portion 3212 and the deformation guide member 323 form a sleeve structure, a gap is formed between the abutting guide portion 3212 and the deformation guide member 323, the elastic member is located in the gap, and two ends of the elastic member are respectively disposed at the bottoms of the abutting portion 3211 and the deformation guide member 323. In this embodiment, the engagement guide portion 3212 and the deformation guide 323 cooperate with each other, so that the engagement assembly 320 is deformed only in the lateral direction, and is not displaced or deformed in the longitudinal direction due to the cooperation between the engagement guide portion 3212 and the deformation guide 323. The assembly connector 300 can be inserted into the positioning through hole 110, and the assembly connector 300 can be connected with the circuit board 100, and then the assembly 320 can be clamped against the circuit board 100 to limit the position of the circuit board 100, so that the circuit board 100 can be tightly attached to the heat sink 200.

In other embodiments, the deformation guide 323 may be disposed through a central axis of the deformation member 322, and the abutting guide portion 3212 is disposed on an outer side of the deformation member 322, so that the deformation guide 323 and the abutting guide portion 3212 form a sleeve structure, a gap is formed between the deformation guide 323 and the abutting guide portion 3212, the elastic member is disposed in the gap, and two ends of the elastic member are disposed at the bottoms of the abutting portion 3211 and the deformation guide 323, respectively.

It should be noted that, in this embodiment, the length of the sleeve structure formed by the abutting guide portion 3212 and the deformation guide 323 can be changed by the elastic member. When the elastic member is in a natural state, the total length of a sleeve structure formed by the clamping guide part 3212 and the deformation guide part 323 and the clamping part 3211 is greater than the inner diameter of the clamping through hole 110; after the elastic element is compressed, the sleeve structure formed by the engaging guide portion 3212 and the deformation guide 323 and the total length of the engaging portion 3211 are smaller than the inner diameter of the engaging through hole 110, so as to ensure that the assembly connector 300 can easily and smoothly pass through the engaging through hole 110, and can be engaged with the other side of the engaging through hole 110 after passing through the engaging through hole 110.

As an alternative embodiment, as shown in fig. 1, the electric control device of the present embodiment includes at least two fitting connectors 300 disposed oppositely; the circuit board 100 is provided with card-positioning through-holes 110 corresponding to the positions and the number of the assembly connectors 300.

In the present embodiment, as shown in fig. 1, since the two assembly connectors 300 are disposed oppositely, the two supporting members 310 correspond to the edges of the two latching through holes 110, so that the assembly connectors 300 and the latching through holes 110 can be aligned accurately in the transverse direction in fig. 1, and the heat sink 200 and the circuit board 100 do not move relatively in the transverse direction in fig. 1 after assembly. In this embodiment, the assembly connectors 300 that are oppositely arranged (symmetrically arranged) can penetrate into the clamping through holes 110 of the circuit board 100 synchronously, and can also press down both sides of the circuit board 100 uniformly at the same time, so that under the condition that the heat sink 200 and the power module 130 are highly attached, mechanical automatic assembly can be conveniently achieved, the precision requirement is low, and the compatibility is high. Further, the assembly connectors 300 on the two sides can simultaneously penetrate through the clamping through holes 110 through mechanical automatic assembly, so that the problem of quality risk of the circuit board 100 caused by uneven stress due to the fact that the two sides of the circuit board 100 are sequentially clamped into the buckles can be solved.

As an alternative embodiment, the spacing of the support members 310 of the fitting connectors 300 arranged opposite to each other is the same as the maximum spacing or the minimum spacing of the detent through holes 110. As shown in fig. 1, in the electronic control device of the present embodiment, the position of the locking through hole 110 on the circuit board 100 corresponds to the position of the assembly connector 300 on the heat sink 200, so that a synchronous design is required to make the locking through hole 110 located in the orthographic projection of the assembly connector 300 on the circuit board 100, which is disposed on the heat sink 200. In order to facilitate the alignment between the assembly connector 300 and the positioning through hole 110, the distance between the supporting members 310 of the assembly connector 300 disposed opposite to each other is the same as the maximum distance or the minimum distance of the positioning through hole 110, so that when the assembly connector 300 is inserted into the positioning through hole 110, the supporting members 310 are attached to the edge of the positioning through hole 110 and inserted into the positioning through hole 110, and correspondingly, the positioning component 320 assembled and connected thereto is inserted along the other edge of the positioning through hole 110 to deform so as to smoothly pass through the positioning through hole 110.

As an alternative, as shown in fig. 1, the electronic control device of this embodiment further includes a fixing member 400 vertically disposed on the heat-conducting surface 210, and the circuit board 100 is provided with a fixing hole 120 corresponding to the fixing member 400. By arranging the fixing member 400 on the heat conducting surface 210 of the heat sink 200 and correspondingly arranging the fixing hole 120 on the circuit board 100, when the heat sink 200 is assembled on the circuit board 100 through the assembly connector 300, the fixing member 400 is inserted into the fixing hole 120, and the fixing member 400 is utilized to limit the relative position of the heat sink 200 and the circuit board 100, so that the arrangement number of the assembly connectors 300 is reduced as much as possible, the number of accessories of the electric control device is reduced, and the production cost of the electric control device is reduced.

As an alternative embodiment, the surface of the fixing member 400 is provided with a tin plating layer. The surface of the fixing member 400 is plated with tin, and it is further preferable that the length of the fixing member 400 is enough to pass through the fixing hole 120, so that the fixing member 400 can be effectively welded with the circuit board 100 after being inserted into the fixing hole 120, and the long-term reliable and effective heat dissipation requirements of the electric control device are met.

As an alternative embodiment, as shown in fig. 1, the heat sink 200 of the present embodiment includes a heat conducting base and a heat dissipating body disposed on the heat conducting base, and a heat conducting surface 210 is disposed on a side of the heat conducting base away from the heat dissipating body. In this embodiment, the heat dissipation body may be a heat dissipation structure such as a heat conduction fin, and a heat conduction base is disposed on the heat dissipation body, so that the heat conduction base is disposed on the circuit board 100. By providing the heat conductive base, the components such as the assembly connector 300 and the fixing member 400 connected to the circuit board 100 can be conveniently disposed on the heat conductive base, so as to connect the heat sink 200 body and the circuit board 100. Moreover, by arranging the heat conducting base, the application range of the heat sink 200 body can be increased, and for circuit boards 100 with different sizes and/or power modules 130 with different sizes on the circuit board 100, the heat conducting base with the corresponding size can be configured to be matched with the circuit board 100 or the power module 130, so that the heat sink 200 body with the same specification can be adopted. Further, the position and size of the heat conducting base where the connector 300 and the fixing member 400 are mounted need to be determined in consideration of the size of the power module 130 attached thereto. When the power module 130 is larger, more mounting connectors 300 and fixtures 400 may be provided and the mounting connectors 300 and fixtures 400 may be evenly distributed around the power module 130; when the power module 130 is small, fewer mount connectors 300 and fixtures 400 may be provided and the mount connectors 300 and fixtures 400 may be evenly distributed around the power module 130;

as an alternative, as shown in fig. 1, in the present embodiment, a thermal conductive adhesive 500 is disposed between the heat sink 200 and the circuit board 100. In this embodiment, the thermal conductive adhesive 500 has a strong thermal conductive property to realize thermal conduction between the power module 130 and the heat sink 200, and the thermal conductive adhesive 500 also has elasticity and high viscosity to make the stress between the heat sink 200 and the power module 130 more uniform and the adhesion more tight, so as to realize a more reliable heat dissipation effect, and the stress transmitted from the heat sink 200 to the circuit board 100 is elastically buffered by the thermal conductive adhesive 500 to protect the circuit board 100 from being damaged. Optionally, the thickness of the thermal conductive adhesive 500 is less than 1.5mm, so as to ensure thermal conduction between the power module 130 and the heat sink 200 and to dissipate heat by using the heat sink 200. Optionally, the thickness of the thermal conductive adhesive 500 is 0.4mm to 1.2mm, for example, the thickness of the thermal conductive adhesive 500 may be 0.4mm, 0.6mm, 0.8mm, 1.0mm, 1.2mm, and the like.

The electric control device, radiator 200 can carry out automatic assembly through automation equipment, and the automatic assembly process is as follows:

the automation equipment grasps the heat sink 200 with the assembly connector 300 and the fixing member 400 fixed in advance, positions the heat sink 200 right above the projection of the circuit board 100, aligns the assembly connector 300 with the locking through-hole 110 on the circuit board 100, aligns the fixing member 400 with the fixing hole 120 on the circuit board 100, and then presses down. After the abutting portion 3211 of the abutting member 321 contacts the positioning through hole 110, the abutting portion 3211 moves laterally to compress the elastic member, and as the assembly connector 300 moves downward, the abutting portion 3211 passes through the positioning through hole 110, and the elastic member returns to its original state, so that the heat sink 200 and the circuit board 100 are in a clamping state, and the heat sink 200 and the power module 130 on the circuit board 100 are effectively attached to each other. Further, the fixing member 400 passes through the fixing hole 120 at the same time, and the fixing member 400 is effectively and rigidly connected with the electric control board after wave soldering, so that the use reliability of the whole electric control device in environments such as vibration is improved.
