[0039] The control board 100 according to the first embodiment of the present invention will be described below with reference to the accompanying drawings.

[0040] According to the control board 100 of the embodiment of the utility model, Figure 1 and Figure 2 As shown, the control board 100 includes a circuit board 1, a heating device 2 and a radiator 3. The circuit board 1 has a snap-in hole 11. The heating device 2 is arranged on the circuit board 1. The radiator 3 includes a heat dissipation portion 31 and a snap-in portion 32. The heat dissipation portion 31 is arranged on a side of the heating device 2 away from the circuit board 1. The snap-in portion 32 includes a spring piece 322. The spring piece 322 extends along a direction from the heat dissipation portion 31 to the circuit board 1. The spring piece 322 includes a bending area to form a protruding portion 322a protruding toward one side of the spring piece 322 in a thickness direction at the bending area. The spring piece 322 is inserted into the snap-in hole 11 and the protruding portion 322a stops at the side of the circuit board 1 away from the heating device 2.

[0041] The circuit board 1 is used for mounting the heating device 2 and other components. The heating device 2 is mounted on the circuit board 1. The heating device 2 generates heat when working. The heat accumulation may affect the normal operation of the control board 100. Optionally, the heating device 2 may be a power device. Therefore, a heat sink 3 is provided on the heating device 2. The heat sink 3 can quickly dissipate the heat generated by the heating device 2 to the air around the heat sink 3 to achieve the heat dissipation and cooling function.

[0042] The heat sink 3 includes a heat dissipation portion 31 and a clamping portion 32. The heat dissipation portion 31 is arranged on one side of the heating device 2. The heat dissipation portion 31 is used for heat dissipation. The contact area between the heat dissipation portion 31 and the heating device 2 is large, which increases the heat dissipation area of ​​the heating device 2 and is beneficial to the heat dissipation of the heating device 2.

[0043] The clamping part 32 is inserted into the clamping hole 11, and the heat sink 3 is clamped and connected with the circuit board 1 through the clamping part 32. The assembly operation of the clamping connection is simple, which can improve the assembly efficiency of the control board 100. The heating device 2 is installed on the circuit board 1. Therefore, after the heat sink 3 is clamped with the circuit board 1, the heat sink 3 is also relatively fixed with the heating device 2. There is no need to set a structure fixedly connected with the heat sink 3 on the heating device 2, which ensures the surface flatness of the heating device 2 and reduces the structural complexity of the heating device 2. The heating device 2 and the heat sink 3 are in good contact, which is conducive to the heat dissipation of the heating device 2. It is not necessary to set an additional fixing to fix the heat sink 3 and the heating device 2, which can save manufacturing costs. And compared with the fixed connection of the heat sink and the heating device by screws, it can avoid damage to the heating device 2 due to improper operation and reduce the damage rate. At the same time, it can also avoid the risk of the human body touching the semiconductor device of the heating device 2, which leads to the introduction of high-voltage static electricity and causes the failure of the heating device 2, so as to improve the working reliability of the control board 100.

[0044] The clamping portion 32 includes a spring piece 322, which extends in a direction from the heat dissipation portion 31 to the circuit board 1. The spring piece 322 includes a bending area to form a protruding portion 322a protruding toward one side in the thickness direction of the spring piece 322 at the bending area. The spring piece 322 is inserted into the clamping hole 11, and the protruding portion 322a stops at a side of the circuit board 1 away from the heating device 2. The spring piece 322 can produce elastic deformation. After the spring piece 322 is deformed and inserted into the clamping hole 11, the spring piece 322 returns to its original state, and the protruding portion 322a of the spring piece 322 protrudes toward the thickness direction of the spring piece 322. The protruding portion 322a limits the clamping portion 32 from moving from the circuit board 1 to the heating device 2, and the spring piece 322 and the clamping hole 11 are mutually clamped to stably connect the heat sink 3 and the circuit board 1.

[0045] The spring piece 322 has a simple structure and is easily inserted into the engaging hole 11 , which can further reduce the difficulty of assembly and improve the assembly efficiency of the control board 100 .

[0046] According to the control board 100 of the embodiment of the utility model, the radiator 3 is connected to the circuit board 1 by the clamping part 32. The assembly operation of the clamping connection is simple, which can improve the assembly efficiency of the control board 100. The radiator 3 is also relatively fixed to the heating device 2, and there is no need to set a structure fixedly connected to the radiator 3 on the heating device 2, which can save manufacturing costs. And compared with the fixed connection between the radiator 3 and the heating device 2 by screws, the damage rate can be reduced, and the risk of failure of the heating device 2 caused by the introduction of high-voltage static electricity can be avoided. By adopting the spring clip 322, the structure of the spring clip 322 is simple and easy to insert into the clamping hole 11, which can further reduce the difficulty of assembly.

[0047] In some embodiments of the utility model, the spring clip 322 is an integrated structure. Compared with setting two separate clamping legs to pass through the clamping hole and be clamped to the circuit board, the spring clip 322 is easier to pass through the clamping hole 11, and it is not easy for one clamping leg to be inserted into the clamping hole while the other clamping leg is not inserted into the clamping hole. This can reduce the defective part rate and improve the assembly efficiency and product qualification rate.

[0048] In some embodiments of the present invention, Figure 3 As shown, the spring piece 322 includes a first spring segment 3221 and a second spring segment 3222 which are arranged in sequence along the direction from the heat dissipation portion 31 to the circuit board 1. The extension directions of the first spring segment 3221 and the second spring segment 3222 are different, so that the spring piece 322 forms a bending area at the connection between the first spring segment 3221 and the second spring segment 3222.

[0049] The spring piece 322 is composed of a first spring segment 3221 and a second spring segment 3222 extending in different directions, which can improve the deformation flexibility of the spring piece 322 and thus improve the adaptability to the engaging holes 11 of different shapes or sizes.

[0050] In some embodiments of the present invention, Figure 3 As shown, the extension length of the first bullet segment 3221 is greater than the extension length of the second bullet segment 3222.

[0051] The first elastic segment 3221 is arranged closer to the heat dissipation portion 31 than the second elastic segment 3222. By arranging a longer first elastic segment 3221, it is ensured that the protruding portion 322a of the connection between the first elastic segment 3221 and the second elastic segment 3222 is stopped at the side of the circuit board 1 away from the heating device 2. In addition, the longer first elastic segment 3221 can adapt to circuit boards 1 and heating devices 2 of different thicknesses, thereby improving the application range of the heat sink 3.

[0052] In some embodiments of the present invention, Figure 4 As shown, the clamping portion 32 further includes a surrounding frame 321, the surrounding frame 321 surrounds the avoidance hole 3211, and the spring piece 322 is arranged at the avoidance hole 3211. Figure 5 As shown, the surrounding frame 321 includes first frame edges 3212 located on both sides of the width of the elastic sheet 322 , and a second frame edge 3213 located on the side away from the heat dissipation portion 31 in the length direction of the elastic sheet 322 , and the second frame edge 3213 is connected between the two first frame edges 3212 .

[0053] The avoidance hole 3211 is located in the middle of the surrounding frame 321. In the length direction of the surrounding frame 321, both ends of the avoidance hole 3211 are shorter than both ends of the surrounding frame 321. In the width direction of the surrounding frame 321, both ends of the avoidance hole 3211 are shorter than both ends of the surrounding frame 321. The first frame edge 3212 and the second frame edge 3213 are involved in surrounding the avoidance hole 3211. This design method can improve the connection stability between the spring sheet 322 and the surrounding frame 321, and the avoidance hole 3211 can limit the spring sheet 322, improve the deformation reliability of the spring sheet 322, and reduce the deviation of the spring sheet 322.

[0054] In some embodiments of the present invention, Figure 5 As shown, the engaging hole 11 is an elongated hole, and the length direction of the engaging hole 11 is consistent with the length direction of the second frame edge 3213 , and the protruding portion 322 a extends toward the width side of the engaging hole 11 relative to the surrounding frame 321 .

[0055] A second frame edge 3213 is connected between the first frame edges 3212. The second frame edge 3213 is located on a side of the snap-in portion 32 away from the heat dissipation portion 31. The second frame edge 3213 can guide the snap-in portion 32 when inserted into the snap-in hole 11, which is beneficial to the smooth insertion of the snap-in portion 32 and improves the assembly efficiency of the control board 100.

[0056] In other embodiments of the present invention, the engaging hole 11 may also be a hole of other shapes, as long as the spring piece 322 can be engaged with the engaging hole 11 .

[0057] In some embodiments of the present invention, Figure 6 As shown, the protruding distance L1 of the protruding portion 322 a of the elastic piece 322 protrudes from the surrounding frame 321 is greater than half of the width L2 of the locking hole 11 .

[0058] The protruding distance L1 of the protruding portion 322a of the spring sheet 322 from the surrounding frame 321 is greater than half of the width L2 of the engaging hole 11 . The protruding distance L1 of the protruding portion 322a from the surrounding frame 321 is the distance between the side surface of the surrounding frame 321 away from the spring sheet 322 and the protruding portion 322a of the spring sheet 322 .

[0059] After being inserted into the snap-in hole 11, the spring piece 322 will be deformed along the width direction of the snap-in hole 11, and the protruding portion 322a of the spring piece 322 will pass through the snap-in hole 11. The rebound force of the spring piece 322 can lock the heat sink 3 and the circuit board 1 to achieve automatic locking, thereby ensuring that the heat sink 3 and the heating device 2 fit well and improving the heat dissipation effect of the heating device 2.

[0060] In some embodiments of the present invention, Figure 4 and Figure 5 As shown, one end of the spring piece 322 close to the heat dissipation portion 31 is connected to the surrounding frame 321 or the heat dissipation portion 31, and one end of the spring piece 322 close to the second frame edge 3213 is spaced apart from the surrounding frame 321. One end of the spring piece 322 close to the second frame edge 3213 is spaced apart from the second frame edge 3213, which is beneficial to the elastic deformation and processing of the spring piece 322.

[0061] In some embodiments of the present invention, Figure 4 As shown, there are two clamping parts 32 , which are disposed on both sides of the heat dissipation part 31 , and the protruding parts 322 a of the spring pieces 322 of the clamping parts 32 on both sides protrude in directions approaching or moving away from each other.

[0062] The heat sink 3 is connected to the circuit board 1 by two clamping parts 32, which can improve the connection stability between the heat sink 3 and the circuit board 1. The two clamping parts 32 make the force on the heat sink 3 uniform and the limiting of the heat sink 3 more stable.

[0063] The protruding parts 322a of the spring pieces 322 of the clamping parts 32 on both sides protrude in directions toward or away from each other. The forces generated by the clamping parts 32 are opposite, which can reduce the situation where the clamping parts 32 are disengaged from the clamping holes 11 when subjected to force in a certain direction, thereby improving the connection stability between the heat sink 3 and the circuit board 1.

[0064] In some embodiments of the present invention, Figure 1 and Figure 7 As shown, the control board 100 further includes: a heat-conducting insulating member 4 , which is disposed between the heating device 2 and the heat dissipating portion 31 , and two clamping portions 32 are disposed on both sides of the heat-conducting insulating member 4 .

[0065] The heat sink 3 is generally a metal part, which has good thermal conductivity and strong structural reliability. The heating device 2 is an electrical device. When the distance between the pins on the heating device 2 and the heat sink 3 is small and the voltage of the heating device 2 is large, there is a risk of voltage breakdown between the pins and the heat sink 3.

[0066] Therefore, a thermally conductive insulating member 4 is provided between the heating device 2 and the heat dissipation portion 31. The thermally conductive insulating member 4 can conduct the heat of the heating device 2 to the heat dissipation portion 31, which is beneficial to the heat dissipation of the heating device 2. Moreover, the thermally conductive insulating member 4 is an insulating member, which can increase the creepage distance between the pins of the heating device 2 and the heat sink 3, reduce the risk of voltage breakdown, and improve the safety of the control board 100.

[0067] In addition, the heat sink 3 is connected to the circuit board 1 via the clamping portion 32, and the thermally conductive insulating member 4 is arranged between the heating device 2 and the heat dissipation portion 31. The heat sink 3 is relatively fixed to the thermally conductive insulating member 4, and there is no need to additionally arrange fixing members to connect the thermally conductive insulating member 4 and the heat sink 3, which can improve assembly efficiency and save manufacturing costs.

[0068] The two clamping parts 32 are located on both sides of the thermally conductive insulating member 4 , so that the force on the thermally conductive insulating member 4 is uniform, the limiting of the thermally conductive insulating member 4 is more stable, and the shaking and falling out of the thermally conductive insulating member 4 can be reduced, thereby improving the working stability of the thermally conductive insulating member 4 .

[0069] It can be understood that the thermally conductive insulating member 4 is used to increase the creepage distance between the pins of the heating device 2 and the heat sink 3 , so the thickness of the thermally conductive insulating member 4 is selected according to the distance between the heating device 2 and the heat sink 3 , and according to the voltage of the heating device 2 .

[0070] In some embodiments of the utility model, the thermally conductive insulating member 4 is interference fit with the heating device 2 and the heat dissipation portion 31, and the thermally conductive insulating member 4 is tightly fitted with the heating device 2 and the heat dissipation portion 31, which can improve the connection stability of the heat sink 3, the thermally conductive insulating member 4, the heating device 2 and the circuit board 1.

[0071] The heat sink 3 is connected to the circuit board 1 by the clamping portion 32, thereby fixing the heat conductive insulating member 4 and the heat sink 3 relatively. The length of the spring piece 322 can be selected according to the thickness of the heat conductive insulating member 4, the thickness of the heating device 2 and the thickness of the circuit board 1.

[0072] The distance from the protruding portion 322a of the spring piece 322 to the side of the heat dissipation portion 31 close to the circuit board 1 must be greater than or equal to the sum of the thickness of the thermally conductive insulating member 4, the thickness of the heating device 2 and the thickness of the circuit board 1, so as to ensure that after the clamping portion 32 is inserted into the clamping hole 11, the protruding portion 322a of the spring piece 322 is located on the side of the circuit board 1 away from the heating device 2, thereby improving the clamping reliability of the clamping portion 32.

[0073] In some embodiments of the present invention, Figure 3 and Figure 7 As shown, the two clamping portions 32 are disposed on both sides of the heat-conducting insulating member 4 in the length direction.

[0074] The two clamping parts 32 are located on both sides of the heat-conducting insulating member 4 in the length direction, which can limit the heat-conducting insulating member 4 more stably, reduce the situation where the heat-conducting insulating member 4 shakes and falls out, and improve the working stability of the heat-conducting insulating member 4.

[0075] In other embodiments of the present invention, the two clamping portions 32 are disposed on two sides of the thermally conductive insulating member 4 in the width direction.

[0076] In some embodiments of the present invention, Figure 3 As shown, the protruding parts 322a of the spring pieces 322 of the clamping parts 32 on both sides protrude towards each other, and the minimum distance L3 between the protruding parts 322a on both sides is greater than the dimension L4 of the thermally conductive insulating member 4 in the spacing direction of the clamping parts 32 on both sides.

[0077] The minimum distance between the spring pieces 322 is greater than the length of the heat-conducting insulating member 4, so that the spring pieces 322 will not contact and squeeze the heat-conducting insulating member 4, and the clamping portion 32 will not contact and squeeze the heat-conducting insulating member 4, thereby avoiding interference and improving the working reliability of the clamping portion 32 and the heat-conducting insulating member 4.

[0078] In some embodiments of the present invention, the heat-conducting insulating member 4 is a prefabricated gasket and has a covering area larger than that of the heating device 2 so as to completely cover the heating device 2 .

[0079] The thermally conductive insulating member 4 is located between the heating device 2 and the heat dissipation portion 31. The edges of the thermally conductive insulating member 4 exceed the heating device 2 or are flush with the heating device 2 to completely cover the heating device 2. The thermally conductive insulating member 4 can increase the creepage distance between the pins of the heating device 2 and the heat sink 3, reduce the risk of voltage breakdown, and improve the safety of the control board 100.

[0080] In other embodiments of the present invention, the heat-conducting insulating member 4 is a layer structure directly processed on the heating device 2 or the heat sink 3, for example, processed on the heating device 2 or the heat sink 3 by coating or pouring glue.

[0081] In some embodiments of the present invention, the heat dissipation part 31 and the clamping part 32 are an integrated part, which can improve the integrity of the heat sink 3 and improve the structural stability of the heat sink 3. When the control board 100 is assembled, the heating device 2 is first mounted on the circuit board 1, and the heat conductive insulating member 4 is placed on the heating device 2. Then, the clamping part 32 of the heat sink 3 is clamped and connected with the circuit board 1, and the heat dissipation part 31 and the heat conductive insulating member 4 are assembled to complete the assembly of the control board 100.

[0082] In some other embodiments of the utility model, the heat dissipation part 31 and the clamping part 32 are separate parts. When the control board 100 is assembled, the clamping part 32 can be firstly clamped and connected with the circuit board 1, and then the heating device 2 is mounted on the circuit board 1, the heat conductive insulating member 4 is placed on the heating device 2, and the heat dissipation part 31 is arranged on the heat conductive insulating member 4, and finally the heat dissipation part 31 and the clamping part 32 are connected to complete the assembly of the control board 100.
