Detailed Implementation

[0025] This utility model provides an electronic control structure and an outdoor unit for an air conditioner. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit the scope of protection of this utility model.

[0026] Please see Figures 1-2 , Figures 4-5This utility model provides an electrical control structure, including a first fixing plate 1 vertically arranged for mounting a main control board 10, a second fixing plate 2 for mounting a terminal block 20, and a third fixing plate 3 for mounting a drive board 30. The first fixing plate 1 includes a main control board mounting part 11 and a first connecting part 12 fixedly connected to one side of the main control board mounting part 11. The side wall of the first connecting part 12 is provided with a first hanging part 13 with an opening facing downward. The first hanging part 13 is used to hang with a first hanging hole 51 on a middle partition plate 5, and the side wall of the first connecting part 12 facing the middle partition plate 5 is used to abut against the side wall of the middle partition plate 5. The first connecting part 12 is also fixed to the middle partition plate 5 by a first fastener 14. The second fixing plate 2 includes a terminal block mounting part 21 and a second connecting part 22 fixedly connected to one side of the terminal block mounting part 21. The side wall of the second connecting part 22 is provided with a second hanging part 23 with an opening facing downward. The main control board mounting part 11 is provided with a vertically extending second hanging hole 111. The second hanging part 23 is hung with the second hanging hole 111, and the side wall of the second connecting part 22 facing the main control board mounting part 11 abuts against the outer side wall of the main control board mounting part 11. The second connecting part 22 is also fixed to the outer side wall of the main control board mounting part 11 by a second fastener 24. The third fixing plate 3 is fixed in the through hole of the middle partition plate 5 by a third fastener 31.

[0027] Please see Figure 6 The partition 5 divides the outdoor unit of the air conditioner into a fan chamber and a duct chamber, with the duct chamber located on the outside of the partition 5. When it is necessary to assemble the electrical control structure onto the partition 5, the third fixing plate 3, which is equipped with the drive plate 30, can be fixed by driving the third fastener 31 (screw / bolt) into the corresponding hole structure on the third fixing plate 3 and the partition 5. Since the third fixing plate 3 is installed in the through hole of the partition 5, which is the inlet of the fan duct, the airflow direction of the duct can be used to cool the electrical components on the drive plate 30. Align the first mounting part 13 on the first fixing plate 1 with the first mounting hole 51 on the partition 5, and hang the first mounting part 13 in the first mounting hole 51. Use the first connecting part 12 to abut against the side wall of the partition 5 to achieve initial positioning of the first fixing plate 1. Then, the worker can easily fix the first fixing plate 1 onto the partition 5 using the first fastener 14 (screw / bolt). Similarly, the second fixing plate 2 is initially positioned by hanging the second hook part 23 in the second hook hole 111, using the second connecting part 22 and the side wall of the main control board mounting part 11 to abut against each other, and then finally fixed by the second fastener 24 (screw / bolt).

[0028] In the above-mentioned electronic control structure, by setting a first hook part 13 on the first fixed plate 1, setting a first hook hole 51 on the middle partition plate 5, setting a second hook part 23 on the second fixed plate 2, and setting a second hook hole 111 on the first fixed plate 1, the first fixed plate 1 and the second fixed plate 2 are initially positioned by hooking, and then the first fastener 14 and the second fastener 24 are used to achieve final fixation, thereby enabling one person to easily assemble.

[0029] Please see Figure 1 and Figure 2 In some embodiments, the first connecting portion 12 includes an L-shaped plate 121 integrally bent with one side of the main control board mounting portion 11, and an abutment plate 122 integrally bent with the side wall of the L-shaped plate 121; the first hanging portion 13 is disposed on the upper part of the abutment plate 122 and integrally bent with the abutment plate 122; the abutment plate 122 is used to abut against the side wall of the partition plate 5, and the first fixing plate 1 is fixed to the partition plate 5 by the first fastener 14. The L-shaped plate 121 causes the main control board mounting portion 11 to be recessed, which on the one hand changes the position of the second fixing plate 2 connected to the first fixing plate 1, and on the other hand allows a certain distance to be maintained between the main control board 10 on the main control board mounting portion 11 and the outer casing 40 of the outdoor unit of the air conditioner. When assembling the first fixing plate 1, after the first hook part 13 is hung in the first hook hole 51, the side wall of the abutment plate 122 will abut against the side wall of the middle partition plate 5. The first hook part 13 and the abutment plate 122 are used to limit the initial positioning of the first fixing plate 1. The structure is simple, and each plate of the first fixing plate 1 is integrally formed by bending, which has sufficient structural rigidity to support the main control plate 10.

The "<" shaped deformation strip 155 and the insertion post 154 are used to insert into the insertion hole 101 of the main control board 10. The outer side of the abutment block 153 is used to abut against the back of the main control board 10. The outer deformation strip 152 is used to surround the periphery of the main control board 10. The buckle body 151 is fixedly connected to the main control board mounting portion 11, and each outer deformation strip 152 faces outward, so that multiple outer deformation strips 152 form a limiting cavity, facilitating the limiting of the periphery of the main control board 10. Furthermore, the outer deformation strip 152 has deformation capability, allowing the main control board 10 to be easily inserted into and removed from the limiting cavity. The deformation of the "<" shaped deformation strip 155 is then utilized to secure the main control board 10's insertion hole 101 within the "<" shaped deformation strip 155, preventing the main control board 10 from falling out of the "<" shaped deformation strip 155.

[0031] Please see Figure 2 In some embodiments, the L-shaped plate 121 has a plurality of weight-reducing holes 1211 extending along its height direction. The weight-reducing holes 1211 are provided to reduce the weight of the first fixing plate 1.

In practical applications, multiple terminal blocks 20 are mounted on the terminal block mounting plate 211, and electrical components such as transformers can also be mounted on the relief plate 212. The relief plate 212 is bent outward to avoid pipes located below the terminal block mounting portion 21, making full use of the pipe cavity space while avoiding impact on the pipes.

[0034] Please see Figure 1 and Figure 4 In some embodiments, the second connecting portion 22 includes a first connecting plate 221 integrally bent to one side of the terminal block mounting plate 211, and a second connecting plate 222 integrally bent to one side of the second connecting plate 221; the second hook portion 23 is disposed on the upper part of the second connecting plate 222 and integrally bent to the second connecting plate 222; the second connecting plate 222 abuts against the side wall of the main control board mounting portion 11, and the second fixing plate 2 is fixed to the first fixing plate 1 by the second fastener 24. In this embodiment, the first connecting plate 221 is an inclined plate forming a certain angle with the terminal block mounting plate 211, used to change the position of the terminal block mounting plate 211 in the pipe cavity. Similarly, the second hook portion 23 and the second connecting plate 222 are used to limit the initial positioning of the second fixing plate 2, which has a simple structure, and the plates of the second fixing plate 2 are integrally formed by bending, providing sufficient structural rigidity to support the multiple electrical components mounted thereon.

To achieve a stable connection between the deformable frame 32 and the third fixing plate 3, screws / bolts can be driven into the corresponding hole structures. In addition, by utilizing the deformation characteristics of the deformable frame 32, the drive plate 30 can be easily installed in the inner cavity of the deformable frame 32 to achieve the initial positioning of the drive plate 30, and then the fifth fastener 33 (screws / bolts) is used to finally fix the drive plate 30 to the third fixing plate 3.
