Abstract
Description
Technical Field
[0001] This utility model relates to the field of air conditioning technology, and in particular to an electronic control structure for air conditioning components. Background Technology
[0002] An air conditioning system consists of an outdoor unit and an indoor unit, and its operation relies on the circulation of refrigerant between them. After being throttled and depressurized in the outdoor unit, the refrigerant is transported to the indoor unit through pipes, where it achieves cooling / heating functions through heat exchange with the indoor air. However, in actual installation environments, due to the large size of the outdoor unit and limited installation space, it is often forced to be installed far away from the indoor unit (such as in high-rise building equipment platforms or narrow balconies). When the refrigerant is transported in long-distance pipes, it will undergo unintended heat exchange with the external environment—absorbing heat from the environment and heating up in cooling mode, and dissipating heat and cooling down in heating mode. Therefore, a secondary throttling device needs to be developed to meet these scenarios. At the same time, the secondary throttling device must also be compact. The main components of the secondary throttling device are the refrigerant circuit system and the electronic control circuit board. To achieve the requirement of small size, the layout of these main structures needs to be optimized. Utility Model Content

[0020] This utility model provides an electronic control structure for air conditioning components. 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 this utility model.

Therefore, they should not be construed as limitations on this utility model. Furthermore, "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "multiple" means two or more.
[0022] Please see Figure 1This utility model provides an electrical control structure for air conditioning accessories, including a support plate 1 and a circuit board 2, a guide rail assembly, and a cable clamp assembly, which are fixed on the support plate 1 and arranged sequentially from left to right. The guide rail assembly includes a first guide rail 31 and a second guide rail 32. The first guide rail 31 is located above the second guide rail 32, and the first guide rail 31 and the second guide rail 32 are arranged in the same direction. A high-voltage terminal 51 is snapped onto the upper part of the first guide rail 31, and a low-voltage terminal 52 is snapped onto the lower part of the second guide rail 32. The cable clamp assembly includes a first cable clamp 41 and a second cable clamp 42 arranged vertically. The first cable clamp 41 is used to clamp high-voltage cables. The first cable clamp 41 is used to clamp low-voltage cables. It also includes a plurality of support members 6. The support members 6 are fixed on the support plate 1 and snapped onto the support plate 1 to support the circuit board 2. Specifically, both the first guide rail 31 and the second guide rail 32 extend vertically. When the high-voltage terminal 51 is fixed to the upper part of the first guide rail 31 and the low-voltage terminal 52 is fixed to the lower part of the second guide rail 32, sufficient distance can be ensured between high-voltage and low-voltage circuits within a limited space, preventing high-voltage circuits from affecting low-voltage circuits. Furthermore, the first cable clamp 41 and the second cable clamp 42 respectively hold the high-voltage and low-voltage cables, also preventing high-voltage circuits from affecting low-voltage circuits. The electrical control structure of this invention is only used to control the electronic expansion valve and relay communication of the refrigerant circuit system, resulting in low load and minimal heat generation. Based on this, the invention uses multiple support members 6 to support the circuit board 2, fixing the circuit board 2 while ensuring it does not contact the support plate 1, leaving ample space for better heat dissipation. With both low heat generation and good heat dissipation, the electrical control structure of this invention does not require a matching radiator (such as a small fan), thus greatly reducing the size of air conditioning components.
[0023] Please see Figure 2 and Figure 3 In one embodiment, the support member 6 includes a first buckle 61, a support rod 62, and a second buckle 63 arranged sequentially from top to bottom. The circuit board 2 has multiple first mounting holes, through which the first buckle 61 passes and engages with the circuit board 2. The support plate 1 has multiple second mounting holes, through which the second buckle 63 passes and engages with the support plate 1. Specifically, the support rod 62 creates a certain distance between the first buckle 61 and the second buckle 63. After the support member 6 is engaged with the circuit board 2 and the support plate 1 respectively, a certain space exists between the circuit board 2 and the support plate 1, which facilitates heat dissipation.
[0024] Preferably, the plurality of first mounting holes are distributed along the edge of the circuit board 2, so that each side of the circuit board 2 can be stably fixed to the support plate 1. The plurality of second mounting holes are provided corresponding to the plurality of first mounting holes.
[0025] Please see Figure 4In one embodiment, the first latch 61 includes a first elastic latching structure 611 and an upper support structure 612 disposed vertically. The first elastic latching structure 611 passes through a first mounting hole, and its bottom surface abuts against the top surface of the circuit board 2. The upper support structure 612 abuts against the bottom surface of the circuit board 2. The top of the first elastic latching structure 611 is elastic, deforming under pressure when passing through the first mounting hole, and springing back after passing through. The distance between the first elastic latching structure 611 and the upper support structure 612 is equal to or slightly less than the thickness of the circuit board 2, thereby clamping the circuit board 2 between the first elastic latching structure 611 and the upper support structure 612.
[0026] Please see Figure 5 In one embodiment, the first elastic snap-fit structure 611 includes a first support portion 6111 and two first wings 6112 arranged at acute angles. One end of the first support portion 6111 is connected to the connection point of the two first wings 6112, and the other end is connected to the upper support structure 612. Specifically, the first wings 6112 are elastic, and the distance between the bottom ends of the two first wings 6112 is greater than the diameter of the first mounting hole when they are not compressed. When passing through the first mounting hole, the two first wings 6112 are compressed and deformed towards the middle first support portion 6111, and then return to their original position after passing through.
[0027] Please see Figure 4 In one embodiment, the second buckle 63 includes a lower support structure 631 and a second elastic snap-fit structure 632 disposed vertically. The bottom surface of the lower support structure 631 abuts against the top surface of the support plate 1. The second elastic snap-fit structure 632 passes through a second mounting hole, and its top surface abuts against the bottom surface of the support plate 1. The bottom of the second elastic snap-fit structure 632 is elastic, deforming under pressure when passing through the second mounting hole, and springing back after passing through. The distance between the second elastic snap-fit structure 632 and the lower support structure 631 is equal to or slightly less than the thickness of the support plate 1, thereby clamping the support plate 1 between the second elastic snap-fit structure 632 and the lower support structure 631.
[0028] Please see Figure 5 In one embodiment, the second elastic snap-fit structure 632 includes a second support portion 6321, a crossbar portion 6322, and two second wings 6323 respectively disposed at both ends of the crossbar portion 6322; the second wings 6323 extend upward; one end of the second support portion 6321 is connected to the connection point of the two crossbar portions 6322, and the other end is connected to the lower support structure 631. The distance between the top tips of the two second wings 6323 in the non-compression state is greater than the diameter of the second mounting hole. When passing through the second mounting hole, the second wings 6323 are compressed inward, and spring back to their original position after passing through the second mounting hole.
[0029] Please see Figure 3 and Figure 4 In one embodiment, the support member 6 further includes a side elastic pressing structure 64; the side elastic pressing structure 64 is connected to the lower support structure 631; the side elastic pressing structure 64 includes a first vertical portion 641 extending upward, a bent portion 642 extending downward and inward, and a second vertical portion 643 extending upward, arranged sequentially; the first vertical portion 641 and the bent portion 642 are used to provide a rebound force; the second vertical portion 643 is used to abut against the side wall of the circuit board 2. The side elastic pressing structure 64 provides an inward thrust, and when multiple side elastic pressing structures 64 abut against the peripheral side surface of the circuit board 2 from different directions, the circuit board 2 can be fixed in the up, down, left, and right directions.
[0030] Please see Figure 1 In one embodiment, protrusions 33 are respectively provided on the top of the first guide rail 31 and the bottom of the second guide rail 32. The protrusions 33 are used to position the high-voltage terminal 51 and the low-voltage terminal 52. By installing the high-voltage terminal 51 and the low-voltage terminal 52 onto the first guide rail 31 and the second guide rail 32 respectively, maintenance and replacement of the high-voltage terminal 51 and the low-voltage terminal 52 can be facilitated. There is friction between the high-voltage terminal 51 and the first guide rail 31, requiring force to move the high-voltage terminal 51 on the first guide rail 31, thereby disengaging it from the bottom of the first guide rail 31. Similarly, there is friction between the low-voltage terminal 52 and the second guide rail 32, requiring external force to drive relative movement.
[0031] In summary, this invention optimizes the layout by rationally arranging the circuit board 2, guide rail assembly, and cable clamp assembly, significantly reducing cable usage and effectively minimizing the overall size of the electrical control structure. This makes it more compact and lightweight, facilitating installation and integration within air conditioning components. When used in secondary throttling devices, its size can be further reduced. Furthermore, this invention uses multiple support members 6 to fix and support the circuit board 2. These support members 6 are tightly engaged with the support plate 1, providing stable support for the circuit board 2. Simultaneously, this mounting method greatly improves heat dissipation for the circuit board 2. Combined with the low load characteristics of the circuit board 2 itself, the entire electrical control structure does not require additional heat dissipation structures during operation. This not only reduces production costs but also further contributes to the reduction in overall size, improving the space utilization of air conditioning components and the operational efficiency and reliability of the electrical control structure.
