[0023] 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 protection scope of the present utility model.

[0024] like Figures 1-4 As shown, this utility model provides a technical solution: a power platform adaptable to different control components, including a power platform body 1 and a control component 3 detachably connected to it via a snap-fit ​​structure 2. The power platform body 1 is provided with a single-phase live wire interface group 11 for connecting to a single-phase power supply, a composite interface group 12 for connecting a three-phase power supply and relay control equipment, and an expansion interface group 13 for compatibility with external communication modules. The control component 3 is electrically connected to the power platform body 1 via a pin-type connector 4.

[0025] The control component 3 includes a touch screen 31 or a physical knob 32. Users can choose different control components 3 according to their operating habits and specific needs. For example, in a home setting where intuitive display and convenient operation are required, the touch screen 31 can be selected, and users can view the device's operating status and set parameters through the touch screen. In an industrial control setting where simple and reliable operation is required, the physical knob 32 can be selected, and operators can quickly adjust the device parameters by rotating the knob, adapting to harsh industrial environments.

[0026] The power platform body 1 includes a base 10 and a top mounting base 15. The base 10 adopts a polygonal shell structure. Taking the octagonal design in this embodiment as an example, it has significant advantages over traditional square / circular structures: the eight sides of the octagon provide regular and symmetrical planar areas, which facilitates the arrangement of functional modules such as the single-phase live wire interface group 11, the composite interface group 12, and the expansion interface group 13 on different sides. The spacing between each interface area is uniform, which avoids wiring interference and provides sufficient space for internal wiring. The geometric symmetry of the octagon allows for stable installation at multiple angles through the fixing holes on multiple sides. For example, in smart home scenarios, it can be vertically or horizontally embedded into the wall box, and in industrial control scenarios, it can be fixed to the control cabinet rail through the mounting holes on both sides, adapting to diverse installation environments.

[0027] The polygonal structure can also adopt a hexagonal design. The six sides of the hexagon can also achieve functional partitioning: for example, the power input side, the device connection side, and the communication expansion side are arranged on three main sides, and the remaining three sides are arranged as heat dissipation sides and guide groove sides. This not only maintains the rationality of the interface layout, but also simplifies mold processing by reducing the number of corners. Whether it is an octagon or a hexagon, the core of the polygonal design is to form multiple functional partitioning surfaces through a regular geometric shape. The guide grooves and interface groups on each side can be adjusted in layout according to the number of sides, and the structural strength characteristics of the polygon are used to improve the impact resistance of the shell.

[0028] Taking the octagonal base 10 as an example, it circumferentially includes a power input side 10a, a device connection side 10b, a communication expansion side 10c, a heat dissipation side 10d, and symmetrically distributed first and second guide groove sides 10e and 10f. The functional definition of each side is based on reasonable allocation of the number of sides: the power input side 10a and the device connection side 10b serve as the main electrical interface area and undertake single-phase / three-phase power access functions; the communication expansion side 10c and the heat dissipation side 10d are arranged adjacent to each other, facilitating the collaborative design of external communication modules and internal heat dissipation structures; the symmetrically arranged guide groove sides ensure force balance during insertion of the control assembly, avoiding tilting and misplacement caused by single-sided guidance. This polygonal layout mode can be flexibly adapted to interface components of different size specifications by adjusting the number of sides, while meeting the requirements of GB / T 14048.7-2017 "Low-voltage Switchgear and Controlgear" regarding mechanical strength of the housing.

[0029] The base 10 circumferentially includes a power input side 10a, a device connection side 10b, a communication expansion side 10c, and a heat dissipation side 10d. The outer walls of the opposite sides are respectively provided with axially extending guide grooves 101, and the inner side walls of the guide grooves 101 are provided with elastically deformable latches 102 made of PA66 engineering plastic. The tips of the latches 102 protrude from the inner wall surface of the guide grooves 101. When connected with external connecting components such as the control assembly 3, the corresponding structures of the external connecting components, such as the protrusions on the edges of the control assembly 3, are inserted into the guide grooves 101, and the latches 102 are elastically deformed and fixed with the corresponding structures, achieving stable connection of the power platform and the external connecting components. During installation, the guide grooves 101 guide the external connecting components to the correct position, avoiding misplacement and ensuring correct docking of the pin-type connector 4.

[0030] The top mounting seat 15 is provided with an isolation groove 14, and the lower end surface of the control assembly 3 is provided with an isolation boss 33 complementary in shape to the isolation groove 14, for forming an electrical gap for strong and weak current isolation and achieving installation guidance.

[0031] The single-phase live wire interface group 11 is arranged at the power input side 10a and is used to connect to a 220V single-phase power supply to supply power to household or small office equipment; the composite interface group 12 is arranged at the equipment connection side 10b and includes side-by-side arranged normally open interfaces 121, normally closed interfaces 122 and a three-phase live wire interface group 123, the normally open interfaces 121 and the normally closed interfaces 122 are respectively connected to the normally open contact and the normally closed contact of the relay inside the power platform main body 1, and can meet the control and power supply requirements of industrial equipment such as three-phase motors; the expansion interface group 13 is arranged at the communication expansion side 10c and includes a first communication interface 131 and a second communication interface 132 supporting multiple communication protocols, including wired protocols such as RS-485, Ethernet, etc. and wireless protocols such as Wi-Fi, Bluetooth, etc., which can be compatible with multiple external communication modules to realize communication between the power platform and external equipment, for example, connecting with industrial sensors through the RS-485 interface to collect data in real time; uploading the device status to the cloud server through the Wi-Fi interface to realize remote monitoring.

[0032] The buckle structure 2 includes a buckle 21 arranged at the side edge of the top mounting seat 15 and a clamping groove 22 arranged at the corresponding side edge of the control assembly 3, and when installing, the clamping groove 22 of the control assembly 3 is aligned with the buckle 21 of the top mounting seat 15, and then pressed to be buckled; when disassembling, the buckle 21 is pulled to be separated from the clamping groove 22, which is convenient to operate and easy to maintain and replace.

[0033] The top mounting seat 15 is provided with an isolation groove 14, and the lower surface of the control assembly 3 is provided with an isolation boss 33 which is complementary in shape to the isolation groove 14. This complementary design not only realizes electrical isolation, but also plays a role in precise guidance. When installing the control assembly 3, the isolation boss 33 can be accurately embedded along the profile of the isolation groove 14, just like a key inserted into a lock hole, which further ensures the accurate relative position of the control assembly 3 and the power platform main body 1. During the embedding of the isolation boss 33 into the isolation groove 14, an electrical isolation gap is formed between the two. This gap can effectively block the electromagnetic interference generated by the strong current loop inside the power platform main body 1, preventing it from affecting the weak current signal of the control assembly 3. At the same time, the electrical isolation gap also avoids the safety problems such as short circuit caused by accidental contact between strong current and weak current, greatly improving the safety and stability of the equipment operation, and meeting the strict requirements of industrial equipment on electrical isolation.

[0034] The pin connector 4 includes a plug slot part 41 fixed at the bottom of the isolation groove 14 and a pin part 42 fixed at the end of the isolation boss 33, when the isolation boss 33 is embedded into the isolation groove 14, the second conductive terminal of the pin part 42 is inserted into the first conductive terminal of the plug slot part 41 to form an electrical connection, and the guiding structure cooperates with the buckle to ensure accurate butt joint and reliable contact.

[0035] The heat dissipation side 10d of the base 10 is provided with a plurality of heat dissipation grooves 103 arranged side by side, the heat dissipation grooves 103 extend longitudinally along the bottom surface of the base 10, the heat dissipation surface area is increased, the heat dissipation efficiency is improved, and stable operation of the power module under high load is ensured.
