Therefore, the features defined with "first", "second" can be explicitly or implicitly included one or more features.

[0032] The technical solutions in the embodiments of the present application will be described clearly and completely in combination with the accompanying drawings in the embodiments of the present application.

[0033] The power piece mounting structure, control module and electrical equipment provided in the embodiments of the present application solve the problem of low installation efficiency of the mounting piece. The following will be described in combination with the accompanying drawings.

[0034] Please refer to Figure 1 and Figure 2 The power piece mounting structure provided in the embodiments of the present application includes a PCB board 1 and a mounting piece 2. The mounting piece 2 is arranged on one side of the PCB board 1. The mounting piece 2 is provided with a clamping jaw 21 and a positioning column 22 on the side close to the PCB board 1. The PCB board 1 is provided with a clamping hole 11 matched with the clamping jaw 21 and a positioning hole 12 matched with the positioning column 22.

[0035] When the end of the clamping jaw 21 away from the mounting piece 2 extends into the clamping hole 11, the core axis of the positioning column 22 is not perpendicular to the core axis of the positioning hole 12.

[0036] Please refer to Figure 2 and Figure 3 When the mounting piece 2 is installed on the PCB board 1, first, the end of the clamping jaw 21 away from the mounting piece 2 extends into the clamping hole 11. At this time, the core axis of the positioning column 22 is not perpendicular to the core axis of the positioning hole 12. Then, the mounting piece 2 is pushed to move so that the core axis of the positioning column 22 coincides with the core axis of the positioning hole 12. At this time, the clamping jaw 21 is elastically deformed. Then, the mounting piece 2 is pushed towards the PCB board 1. The positioning column 22 gradually extends into the positioning hole 12. The end of the clamping jaw 21 away from the mounting piece 2 gradually extends out of the clamping hole 11. Until the mounting piece 2 abuts against the PCB board 1. The positioning column 22 is completely accommodated in the positioning hole 12. The end of the clamping jaw 21 away from the mounting piece 2 extends out of the clamping hole 11 and is matched with the PCB board 1. Thus, the fixed connection between the mounting piece 2 and the PCB board 1 is realized. The connection structure of the mounting piece 2 and the PCB board 1 has high stability. The connection process is simple and fast. The problem of low installation efficiency of the mounting piece 2 is solved.

[0037] Referring to Figure 2 and Figure 3 In the embodiment, two clamping claws 21 are fixedly connected to the side of the mounting member 2 close to the PCB 1, each clamping claw 21 comprises a clamping hook portion 211 and a connecting portion 212, and the clamping hook portions 211 of the two clamping claws 21 are arranged on the side of the connecting portion 212 in the first direction. In the embodiment, the clamping hole 11 is a rectangular hole, and when the mounting member 2 is mounted on the PCB 1, the connecting portion 212 abuts against the hole wall of the clamping hole 11 in the first direction, and the clamping hook portion 211 abuts against the PCB 1.

[0038] In the embodiment, the positioning column 22 is a circular column, the positioning hole 12 is a circular hole, and the clamping hole 11 is a rectangular hole. In some embodiments of the present application, the positioning column 22 is in any one of the shapes of a circular truncated cone, a circular cone, a hemisphere, a truncated prism, a pyramid, or a prism. The size of the clamping hole 11 is greater than the size of the clamping claw 21, so that the clamping claw 21 can extend into the clamping hole 11. In the embodiment, the diameter of the positioning column 22 is D, the length of the clamping hole 11 is L1, the width of the clamping hole 11 is W1, the length of the clamping claw 21 is L2, and the width of the clamping claw 21 is W2. The clamping hole 11 can extend on the PCB 1 in the opposite direction of the first direction, so that W2≤W1, the width of the clamping hole 11 is greater than the width of the clamping claw 21, and when the mounting member 2 is mounted on the PCB 1, the connecting portion 212 can abut against the side wall of the clamping hole 11 in the first direction. In addition, L2≤L1≤L2+D / 2. By making L2≤L1≤L2+D / 2, not only can the clamping claw 21 extend into the clamping hole 11, but also the occurrence of the positioning column 22 being difficult to align with the positioning hole 12 due to excessive increase in the width of the clamping hole 11 can be reduced, and the efficiency of the mounting member 2 close to the PCB 1 is improved.

[0039] Referring to Figure 2 and Figure 3 In the embodiment, when the clamping hook portion 211 extends into the clamping hole 11, the core axis of the positioning hole 12 is located on the side of the core axis of the positioning column 22 in the first direction. In addition, the positioning column 22 is provided with a guide surface 221, the guide surface 221 is an inclined surface, the guide surface 221 connects the end surface of the positioning column 22 away from the mounting member 2 and the side surface of the positioning column 22, and the provision of the guide surface 221 is beneficial to reduce the collision between the positioning column 22 and the PCB 1, so that the core axis of the positioning hole 12 does not need to completely coincide with the core axis of the positioning column 22 to guide the positioning column 22 to insert into the positioning hole 12.

[0040] Referring to Figure 4 In particular, in some embodiments of the present application, the included angle between the normal direction of the guide surface 221 and the first direction is obtuse, so that when the clamping hook portion 211 extends into the clamping hole 11, the guide surface 221 abuts against the edge of the positioning hole 12 to guide the positioning column 22 to insert into the positioning hole 12.

[0041] Please refer to Figure 3 and Figure 5 The angle between the guide surface 221 and the end surface of the positioning column 22 away from the mounting member 2 is α, 0° < α ≤ 75°. In the embodiment, the value of α is 45°, and in some embodiments of the application, the value of α is any one of 5°, 10°, 15°, 20°, 25°, 30°, 35°, 40°, 50°, 55°, 60°, 65°, 70° and 75°.

[0042] Please refer to Figure 3 and Figure 5 The projection length of the end of the positioning column 22 away from the mounting member 2 in the second direction is L, and the diameter of the positioning column 22 is D, In the embodiment, When , the end surface of the positioning column 22 is too large and the guide surface 221 is too small, which makes it difficult to achieve the expected guiding effect of the guide surface 221. When , the structural strength requirement of the positioning column 22 can be met, and the guiding requirement of the guide surface 221 can also be met.

[0043] Please refer to Figure 2 and Figure 3 The mounting member 2 is provided with a receiving groove 23 for accommodating and fixing the semiconductor power component on the side close to the PCB 1, the receiving groove 23 is integrally formed with a reinforcing column 24, the positioning column 22 is integrally formed on the side of the reinforcing column 24 away from the mounting member 2, and the height of the positioning column 22 is less than the thickness of the PCB 1. When the mounting member 2 is installed on the PCB 1, the reinforcing column 24 abuts against the PCB 1, the positioning column 22 is completely accommodated in the positioning hole 12, and the provision of the reinforcing column 24 is beneficial to enhancing the structural strength of the mounting member 2, thereby improving the protection performance of the mounting member 2 on the semiconductor power component. The mounting member 2 is provided with a weight-reducing hole 25 on the side away from the PCB 1, and the weight-reducing hole 25 penetrates through the mounting member 2 and extends to the reinforcing column 24. The provision of the weight-reducing hole 25 is beneficial to reducing the weight of the mounting member 2, thereby improving the portability of the mounting member 2.

[0044] Please refer to Figure 2 and Figure 3 In addition, the mounting member 2 is provided with a notch 26 on the side close to the PCB 1. When the mounting member 2 is installed on the PCB 1, a gap is formed between the notch 26 and the PCB 1, so that the user can separate the mounting member 2 from the PCB 1 through the notch 26, which is beneficial to the disassembly of the mounting member 2.
