[0015] The first metal connector passes through the first metal through-hole, the second metal through-hole, and the third metal through-hole to connect the ground terminal of the circuit board, the first metal housing, and the second metal housing.

[0016] In one embodiment, one of the first metal housing and the second metal housing is provided with a mounting groove, the circuit board is disposed in the mounting groove, and the ground terminal of the circuit board is fixed to the mounting groove through the second metal connector.

[0033] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0035] Currently, air conditioner outdoor units typically have a photovoltaic control box. This box collects solar energy to reduce the power consumption of the compressor during operation, thus saving electricity. However, existing air conditioner outdoor units are grounded via the casing, while the photovoltaic control box is connected to the metal casing via a PCB board. The separate grounding of both the casing and the photovoltaic control box increases the installation complexity of the outdoor unit and makes later maintenance more difficult.

[0036] This utility model proposes an air conditioner outdoor unit 1000, which aims to reduce the installation complexity of the air conditioner outdoor unit 1000 and the difficulty of subsequent maintenance.

[0037] In one embodiment of this utility model, reference is made to Figures 1 to 5 The outdoor unit 1000 of the air conditioner includes a housing 200, a metal bracket 300, and a photovoltaic control box 100. The metal bracket 300 is connected to the housing 200. The photovoltaic control box 100 includes a metal housing 10 and a circuit board 3. The metal housing 10 is connected to the metal bracket 300 for grounding. The metal housing 10 is provided with a receiving cavity 7. The circuit board 3 is located in the receiving cavity 7. The grounding terminal 31 of the circuit board 3 is connected to the metal housing 10.

[0038] In this embodiment, the outdoor unit 1000 may include a casing 200, a main control box, a main body 400, a photovoltaic control box 100, etc. The casing 200 serves as the external protective structure of the outdoor unit 1000, providing physical protection for components such as the main body 400, the main control box, and the photovoltaic control box 100, and also supporting the structural stability of the entire outdoor unit 1000. The casing 200 effectively prevents the impact of external environmental factors (such as rain, snow, dust, etc.) on the internal components. The main control box, located inside the casing 200, is the core control unit of the outdoor unit 1000. It manages the entire workflow of the outdoor unit 1000, including but not limited to operation control, status monitoring, and fault diagnosis. Through the main control box, precise control of the outdoor unit can be achieved, and the operating mode can be adjusted according to actual conditions to achieve optimal performance. The main body 400, also located inside the casing 200, refers to the main working components of the outdoor unit 1000, such as the condenser and the fan 410. These components directly participate in the cooling or heating process. The main unit 400 communicates with the main control box via an electrical connection, receiving instructions from the main control box and feeding back its own operating status to ensure the coordinated operation of the entire system. The photovoltaic control box 100, also located inside the casing 200, is a crucial component of the outdoor unit 1000, specifically designed to manage and optimize the power consumption of the photovoltaic cells (solar cells). Specifically, the photovoltaic control box 100 monitors and manages the direct current generated by the photovoltaic cells, effectively converting and distributing it to the various electrical components within the outdoor unit 1000. This helps improve the energy efficiency of the entire outdoor unit 1000 system, maximizing the use of renewable energy. The photovoltaic control box 100 can operate independently or exchange data with the main control box via an electrical connection. It can feed back the photovoltaic cell status information (such as power generation and current operating status) to the main control box, allowing the main control box to adjust the operating mode of the entire outdoor unit 1000 based on this information, thereby achieving optimal performance.

[0039] To support the main body 400, the outdoor unit 1000 also includes a metal bracket 300. The metal bracket 300 is housed within the casing 200, and at least some components of the main body 400 are mounted on the metal bracket 300. For example, the fan 410 of the outdoor unit 1000 is mounted on the metal bracket 300. Mounting the fan 410 on the metal bracket not only ensures the stability of the fan 410 during operation, reducing vibration and noise, but also optimizes airflow and improves heat exchange efficiency. Using the metal bracket 300 ensures the components of the main body 400 are securely supported, contributing to the stability and durability of the entire outdoor unit 1000 structure. The metal bracket 300 is also directly connected to the casing 200. This connection not only enhances the overall structural stability of the outdoor unit 1000 but also enables effective grounding of the metal bracket 300, effectively conducting static electricity or leakage current to the ground, thereby protecting the safety of the outdoor unit 1000 and the user.

[0040] Based on the above, to reduce the installation complexity of the outdoor unit 1000 and the difficulty of subsequent maintenance, the photovoltaic control box 100 may specifically include a metal housing 10 and a circuit board 3. The metal housing 10 is connected to the metal bracket 300 to achieve grounding of the metal housing 10. That is, the metal housing 10 not only provides physical protection for the internal circuit board 3, but also achieves effective grounding through its connection with the metal bracket 300. This design can prevent the influence of external electromagnetic interference (EMI) on the circuit board 3 and can safely conduct any static electricity or leakage current to the ground, thereby protecting the safety of the photovoltaic control box 100 and the user. The circuit board 3 is located in the receiving cavity 7 within the metal housing 10 and is responsible for monitoring and managing the DC power generated by the photovoltaic cells, and effectively converting and distributing it to the various electrical components in the outdoor unit 1000. In addition, the circuit board 3 also has communication functions, enabling it to exchange data with the main control box and provide feedback on the status information of the photovoltaic cells (such as power generation status, current operating status, etc.) so as to adjust the operating mode of the entire air conditioning system based on this information. The grounding terminal 31 on circuit board 3 is directly connected to the metal housing 10, thus grounding circuit board 3. Even if circuit board 3 experiences an electrical fault, the current can be quickly conducted to the ground, reducing the risk of electric shock. Since the metal housing 10 and the metal bracket 300 are directly connected and grounded, the need to find a separate grounding path for circuit board 3 is reduced, thereby simplifying the installation process. At the same time, during later maintenance, technicians only need to check this main grounding connection, greatly reducing the difficulty of maintenance.

[0041] The technical solution of this utility model involves setting up a housing 200, a motor metal bracket 300, and a photovoltaic control box 100. The motor metal bracket 300 is connected to the housing 200. The photovoltaic control box 100 includes a metal housing 10 and a circuit board 3. The metal housing 10 is connected to the housing 200 for grounding. The metal housing 10 has a receiving cavity 7, and the circuit board 3 is located in the receiving cavity 7. The grounding terminal 31 of the circuit board 3 is connected to the metal housing 10. That is, the grounding of the photovoltaic control box 100 is achieved by connecting the metal housing 10 to the metal bracket 300, and then connecting the metal bracket 300 to the housing 200. The 200 units are electrically connected, meaning that no additional grounding wire is needed to ensure grounding continuity. The entire grounding path forms a coherent electrical path from the photovoltaic control box 100 to the housing 200, ensuring safe grounding. Furthermore, as the housing 200, metal casing 10, and circuit board 3 are part of the grounding path, they no longer need to be grounded separately. They all share a single grounding on the outdoor unit 1000, thereby reducing the need for multiple independent grounding wires. The reduced number of independent grounding wires also simplifies the installation process and reduces the difficulty of later maintenance.

[0042] In one embodiment of this utility model, reference is made to Figures 1 to 5 The metal housing 10 includes:

[0043] First metal casing 1;

[0044] The second metal housing 2 is connected to the first metal housing 1 via a first metal connector 4a; the second metal housing 2 and the first metal housing 1 enclose the cavity 7; the grounding terminal 31 of the circuit board 3 is connected to at least one of the first metal housing 1 and the second metal housing 2 via the first metal connector 4a or the second metal connector 4b, and at least one of the first metal housing 1 and the second metal housing 2 is connected to the housing 200 for grounding.

[0045] In this embodiment, the first metal housing 1 and the second metal housing 2 each serve as part of the housing of the photovoltaic control box 100, providing physical protection and participating in the formation of the receiving cavity 7. The first metal housing 1 and the second metal housing 2 are interconnected by one or more first metal connectors 4a, jointly enclosing a receiving cavity 7 for accommodating the circuit board 3 and other electronic components. This design ensures that even in a split structure, the first metal housing 1 and the second metal housing 2 can maintain a good electrical connection, thereby achieving natural conductivity. In one example, the first metal housing 1 is provided with a first metal through hole 101, and the second metal housing 2 is provided with a second metal through hole 201. The position of the second metal through hole 201 corresponds to the position of the first metal through hole 101. The first metal connector 4a can be a first screw or a first copper sheet, or other forms of fasteners, depending on the design requirements. In this example, the first metal connector 4a is a first screw. The first screw can include, but is not limited to, slotted screws, socket head cap screws, Phillips head screws, eye bolts, set screws, self-tapping screws, etc., and is not specifically limited here. The first screw passes through the first metal through hole 101 and the second metal through hole 201 to connect the first metal housing 1 and the second metal housing 2.

[0046] The circuit board 3 is housed within the cavity 7 formed by the first metal housing 1 and the second metal housing 2, and its grounding terminal 31 can be connected to at least one metal housing via a first metal connector 4a or an additional second metal connector 4b. That is, the grounding terminal 31 of the circuit board 3, the first metal housing 1, and the second metal housing 2 can be connected as a single unit via one or more first metal connectors 4a; or, if the first metal housing 1 and the second metal housing 2 are connected via one or more first metal connectors 4a, the grounding terminal 31 of the circuit board 3 can be connected to at least one of the first metal housing 1 and the second metal housing 2 via one or more additional second metal connectors 4b. In other words, the grounding terminal 31 of the circuit board 3 can be installed separately on the first metal housing 1 via the second metal connector 4b, or separately on the second metal housing 2 via the second metal connector 4b, or even simultaneously on both the first metal housing 1 and the second metal housing 2 via the second metal connector 4b, thereby ensuring that the circuit board 3 can be effectively grounded through the metal housing. For ease of understanding, and in conjunction with the above example, in another example, the circuit board 3 has a third metal via 301 at the ground terminal 31, and the position of the third metal via 301 corresponds to the position of the first metal via 101. The second metal connector 4b can be a second screw or a second copper sheet, or other types of fasteners, depending on the design requirements. In this example, the second metal connector 4b is a second screw, and the type of the second screw can be similar to that of the first screw, which will not be repeated here. The second screw passes through the first metal via 101 and the third metal via 301 to fix the ground terminal 31 of the circuit board 3 to the first metal housing 1. Furthermore, at least one of the first metal casing 1 and the second metal casing 2 can be connected to the housing 200. For example, the first metal casing 1 is connected to the housing 200; or the second metal casing 2 is connected to the housing 200; or the first metal casing 1 and the second metal casing 2 are respectively connected to the housing 200 to achieve grounding. This means that the entire photovoltaic control box 100 can be connected to the housing 200 via the metal bracket 300 to complete grounding, ensuring that the entire photovoltaic control box 100 and the air conditioner outdoor unit 1000 can effectively and safely conduct static electricity or fault current to the ground, thereby ensuring the safety and stability of the equipment, while reducing the need for additional grounding power and simplifying the installation process.

[0047] In one embodiment of this utility model, reference is made to Figures 1 to 5The first metal housing 1 has a first metal through hole 101, and the second metal housing 2 has a second metal through hole 201. The first metal connector 4a passes through the first metal through hole 101 and the second metal through hole 201 to fix the first metal housing 1 to the second metal housing 2. The circuit board 3 has a third metal through hole 301 at the ground terminal 31. The second metal connector 4b passes through the third metal through hole 301 and the first metal through hole 101 to fix the ground terminal 31 of the circuit board 3 to the first metal housing 1.

[0048] Alternatively, the second metal connector 4b passes through the third metal through-hole 301 and the second metal through-hole 201 to fix the ground terminal 31 of the circuit board 3 to the second metal housing 2.

[0049] In this embodiment, the first metal housing 1 is fixed to the second metal housing 2 by the first metal through-hole 101 and the second metal through-hole 201, forming a stable mechanical connection and ensuring electrical conductivity. The second metal connector 4b can selectively fix the grounding terminal 31 of the circuit board 3 to either the first metal housing 1 or the second metal housing 2, involving two connection methods. Method 1: The second metal connector 4b passes through the third metal through-hole 301 and the first metal through-hole 101 to fix the grounding terminal 31 of the circuit board 3 to the first metal housing 1. Method 2: The second metal connector 4b passes through the third metal through-hole 301 and the second metal through-hole 201 to fix the grounding terminal 31 of the circuit board 3 to the second metal housing 2. In other words, this embodiment provides two different connection methods, allowing the selection of the most suitable grounding method according to the specific application scenario, enhancing the design flexibility of the photovoltaic control box 100. Furthermore, by directly connecting the grounding terminal 31 of the circuit board 3 to the first metal housing 1 or the second metal housing 2 via the second metal connector 4b, the need for additional grounding wires is reduced, making the grounding of the entire photovoltaic control box 100 simpler and more reliable. The second metal connector 4b not only serves as an electrical connection but also enhances the physical connection between the first metal housing 1 or the second metal housing 2 and the circuit board 3, improving the structural stability of the photovoltaic control box 100. In addition, since the first metal housing 1, the second metal housing 2, and the circuit board 3 are all connected via holes and connectors, the assembly process is more intuitive and facilitates subsequent inspection and maintenance.

[0050] In one embodiment of this utility model, reference is made to Figures 1 to 5The first metal housing 1 has a first metal through hole 101, the second metal housing 2 has a second metal through hole 201, and the circuit board 3 has a third metal through hole 301 at the ground terminal 31. The first metal connector 4a passes through the first metal through hole 101, the second metal through hole 201 and the third metal through hole 301 to connect the ground terminal 31 of the circuit board 3, the first metal housing 1 and the second metal housing 2.

[0051] In this embodiment, the electrical connection between the grounding terminal 31 of the circuit board 3, the first metal housing 1, and the second metal housing 2 can be achieved using a single first metal connector 4a, reducing the need for additional connectors or grounding wires. Since the first metal connector 4a runs through all critical components, it not only ensures electrical continuity but also enhances the mechanical strength and stability of the entire photovoltaic control box 100. Furthermore, only one first metal connector 4a is needed to complete the tasks of multiple connection points, reducing assembly complexity and improving production efficiency. Simultaneously, when disassembling or inspecting the photovoltaic control box 100, only a few connectors need to be handled, simplifying maintenance. In addition, by reducing the number of connection points, the risk caused by loose connections or poor contact is reduced, improving the overall reliability of the photovoltaic control box 100.

[0052] In one embodiment of this utility model, reference is made to Figure 3 One of the first metal housing 1 and the second metal housing 2 is provided with a mounting groove 102, the circuit board 3 is disposed in the mounting groove 102, and the ground terminal 31 of the circuit board 3 is fixed to the mounting groove 102 by the second metal connector 4b.

[0053] In this embodiment, a mounting groove 102 for accommodating the entire circuit board 3 can be provided on either the first metal housing 1 or the second metal housing 2, depending on specific design requirements and layout considerations, increasing design flexibility. The design of the mounting groove 102 should take into account the size, shape, and necessary heat dissipation requirements of the circuit board 3. Placing the circuit board 3 within the mounting groove 102 not only provides physical support but also helps position and fix the circuit board 3, preventing it from shifting or loosening due to vibration. Furthermore, since the circuit board 3 is placed within the mounting groove 102, the need for other fixing devices is reduced, making the entire photovoltaic control box 100 structure more concise and compact. The grounding terminal 31 of the circuit board 3 is securely fixed within the mounting groove 102 by the second metal connector 4b, ensuring good electrical contact and mechanical stability. The implementation of the second metal connector 4b has been described in the previous embodiment and will not be repeated here.

[0054] In one embodiment of this utility model, reference is made to Figure 3The first metal housing 1 is provided with the mounting groove 102, and the first metal housing 1 is provided with the third metal connector 4c. The circuit board 3 is provided with the third metal through hole 301 at the ground end 31. The second metal connector 4b passes through the third metal through hole 301 and is threaded to the third metal connector 4c to fix the ground end 31 of the circuit board 3 to the mounting groove 102.

[0055] In this embodiment, the mounting slot 102 of the first metal housing 1 is used to accommodate the entire circuit board 3, providing physical support and positioning. A third metal connector 4c is disposed near the mounting slot 102 and is used to cooperate with the second metal connector 4b to firmly fix the grounding terminal 31 of the circuit board 3 within the mounting slot 102. The type of the third metal connector 4c can be similar to that of the first metal connector 4a or the second metal connector 4b, and will not be elaborated further here. By directly connecting the grounding terminal 31 of the circuit board 3 to the first metal housing 1, the need for additional grounding wires is reduced, making the grounding of the entire photovoltaic control box 100 simpler and more reliable. Furthermore, due to the presence of the mounting slot 102 and the third metal connector 4c, the circuit board 3 can be directly inserted and fixed with the second metal connector 4b, simplifying the assembly steps and improving production efficiency. When the circuit board 3 needs to be disassembled or inspected, only the second metal connector 4b needs to be processed, simplifying maintenance work while ensuring the grounding effect after reinstallation.

[0056] In one embodiment of this utility model, reference is made to Figure 1 , Figure 2 and Figure 6 The first metal housing 1 and / or the second metal housing 2 extend outward with a first mounting portion 5, and the first metal housing 1 and / or the second metal housing 2 are fixed to the housing 200 by the first mounting portion 5.

[0057] In this embodiment, the first mounting part 5 can be provided on either the first metal housing 1 or the second metal housing 2, or both, depending on the specific installation location and requirements. The first mounting part 5 extends outward from the first metal housing 1 and / or the second metal housing 2, and is used to fix the photovoltaic control box 100 to the housing 200 of the air conditioner outdoor unit 1000. The first mounting part 5 can be a separate lug, a metal bracket 300, or other forms of fixing structure, depending on design requirements. The first mounting part 5 can be made of materials with good strength and corrosion resistance, such as stainless steel or aluminum alloy, to ensure a long-term stable mechanical connection between the photovoltaic control box 100 and the housing 200. The first mounting part 5 provides an additional fixing point for the photovoltaic control box 100 on the housing 200, enhancing the physical connection and electrical grounding between the photovoltaic control box 100 and the housing 200. This not only prevents loosening or detachment due to vibration or external force but also reduces the risk of poor contact, improving the overall reliability of the photovoltaic control box 100. Furthermore, thanks to the pre-designed first mounting section 5, installation only requires aligning the photovoltaic control box 100 with the corresponding position and securing it with fasteners, simplifying the installation steps and improving installation efficiency.

[0065] In this embodiment, the first connecting arm 61 and the second connecting arm 62 are arranged opposite to each other to ensure that they can provide sufficient support during installation and fit tightly against the first edge portion 210 in the snap-fit ​​state to prevent loosening. The third connecting arm 63 serves as a connector between the first connecting arm 61 and the second connecting arm 62, connecting them together to form a U-shaped opening 601 for receiving and securing the first edge portion 210 of the housing 200, providing a stable mechanical connection and electrical conduction. The third connecting arm 63 can be designed with a certain degree of elasticity to facilitate smooth snap-fitting against the first edge portion 210 during installation and maintain tight contact after installation. The U-shaped opening 601 should match the dimensions of the first edge portion 210 to ensure a tight fit and stable connection after installation. The design of the U-shaped opening 601 can also include auxiliary structures, such as snaps or grooves, to further enhance the reliability of the fixation.

[0066] In one embodiment of this utility model, reference is made to Figure 1 and Figure 6 At least one of the first connecting arm 61, the second connecting arm 62 and the third connecting arm 63 is connected to the first edge portion 210 via a fifth metal connector 4e.

The fifth metal connector 4e can be of the type of the first metal connector 4a, the second metal connector 4b, the third metal connector 4c, or the fourth metal connector 4d, and will not be described in detail here. In other words, this embodiment adds a fifth metal connector 4e to the original fastening structure, which not only provides mechanical fixation but also ensures good electrical conductivity, helping the photovoltaic control box 100 to achieve reliable grounding.

[0068] In one embodiment of this utility model, reference is made to Figure 1 and Figure 6 At least one of the first connecting arm 61, the second connecting arm 62 and the third connecting arm 63 is provided with a sixth metal through hole 602, and the first edge portion 210 is provided with a seventh metal through hole. The fifth metal connector 4e passes through the sixth metal through hole and the seventh metal through hole to fix the second mounting portion 6 to the first edge portion 210.

[0069] In this embodiment, a sixth metal through hole 602 can be provided at one end of the first connecting arm 61 near the first edge portion 210 to enhance the fixing effect on that side; and / or, a sixth metal through hole 602 can be provided at one end of the second connecting arm 62 near the first edge portion 210 to ensure the fixing effect on the other side; and / or, a sixth metal through hole 602 can be provided in the middle or at both ends of the third connecting arm 63 to enhance the stability of the entire enclosure structure. That is, by providing a sixth metal through hole 602 on at least one of the first connecting arm 61, the second connecting arm 62, and the third connecting arm 63, and providing a seventh metal through hole on the first edge portion 210 of the housing 200, and using a fifth metal connector 4e passing through the sixth and seventh metal through holes to fix the second mounting part 6 to the first edge portion 210, a more stable mechanical connection and reliable electrical grounding are achieved. This method not only simplifies the installation process and improves assembly efficiency, but also enhances the reliability and safety of the system.
