[0017] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0018] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “described” as used herein may also include the plural forms. The terms “comprising,” “including,” “containing,” and “having” are inclusive and therefore indicate the presence of the stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof.

It should also be understood that additional or alternative steps may be used.

[0019] Although terms such as first, second, third, etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another.

Therefore, the example term "below" can include both upper and lower orientations.

[0021] like Figures 1 to 5As shown, according to an embodiment of the present invention, an electronic control assembly 100 is proposed, including an electronic control box 10 and a sensor assembly 20. The electronic control box 10 includes a box body 1 and an electronic control board (not shown in the figure) disposed inside the box body 1. The box body 1 is provided with a mounting part 11, which protrudes from one side wall of the box body 1. The mounting part 11 is provided with a socket 111 and a socket 112 on the side away from the side wall of the box body 1. The socket 112 is located on one side of the socket 111 and communicates with the socket 111. The socket 112 is a channel for the connector 2 to enter the socket 111, so that the user can directly insert the connector 2 into the socket 111 through the socket 112 to complete the installation operation without disassembling other structures of the electronic control box 10.

[0022] The sensor assembly 20 includes a connector 2 and a sensor 3 connected to the connector 2. The sensor 3 is electrically connected to the electronic control board. The signal collected by the sensor 3 can be transmitted to the electronic control board for processing in real time through conductive structures such as wires and connectors. The connector 2 is configured to be installed in the socket 111 through the socket 112 so that the sensor 3 can be connected to the housing 1. After the connector 2 is inserted into the socket 111 through the socket 112, the sensor 3 is positioned synchronously with the connector 2, thus realizing the mechanical fixation of the sensor 3 to the housing 1 and the electrical signal communication with the electronic control board, ensuring convenient disassembly and reliable connection of the sensor 3 on the electronic control box 10.

[0023] The electronic control component 100 of this utility model has a socket 111 and a socket 112 communicating with the socket 111 in the mounting part 11 of the electronic control box 10. The connector 2 of the sensor component 20 is quickly inserted into the socket 111 through the socket 112, realizing convenient disassembly and assembly and reliable connection between the sensor component 20 and the electronic control box 10. This simplifies the installation process of the sensor 3 and improves the assembly efficiency. At the same time, the connection between the connector 2 and the socket 111 ensures the stable fixation of the sensor 3 and the electronic control board, thereby enhancing the overall structural stability and maintenance convenience of the electronic control component 100.

[0024] In some embodiments of this utility model, the connector 2 includes a connected elastic connecting part 21 and a fixing part 22. The elastic connecting part 21 is inserted into the socket 111 through the socket 112, and the sensor 3 is mounted on the fixing part 22. During installation, the sensor 3 is mounted on the fixing part 22, and then the elastic connecting part 21 is aligned with the socket 112 on the mounting part 11 of the control box 10. The elastic connecting part 21 is inserted into the socket 111 along the direction of the socket 112. The elastic deformation of the elastic connecting part 21 achieves the limiting position until the elastic connecting part 21 and the socket 111 form a stable fit, thereby realizing the mechanical fixation of the sensor 3 to the control box 10 and the signal communication with the control board. The fixing part 22 has a mounting hole, which is a through hole that passes through the fixing part 22. The sensor 3 can be directly inserted into the mounting hole to complete the initial positioning without complicated assembly steps, simplifying the assembly process of the sensor 3 and the connector 2. At the same time, the interference fit between the sensor 3 and the mounting hole makes the sensor 3 less prone to loosening or displacement during the operation of the electrical control box 10, ensuring the accuracy of the detection data. The elastic connecting part 21 and the fixing part 22 are integrated structures, such as by injection molding, which simplifies the installation process of the sensor 3 and improves the reliability of the connection and the convenience of maintenance.

[0025] like Figure 2 and Figure 5 As shown, in some embodiments of this utility model, the elastic connecting part 21 includes a connecting block 211 and two first elastic arms 212. The connecting block 211 is connected to the fixing part 22. The ends of the two first elastic arms 212 away from the fixing part 22 are connected to the connecting block 211. The distance between the two first elastic arms 212 gradually increases from the end away from the fixing part 22 to the end closer to the fixing part 22. The two first elastic arms 212 extend into the insertion hole 111 and are limited and engaged with the inner wall of the insertion hole 111 through the end of the first elastic arm 212 facing the fixing part 22.

[0026] Specifically, the connecting block 211 connects the two first elastic arms 212 into a cooperating whole, allowing them to deform synchronously. The two first elastic arms 212 are symmetrically distributed on both sides of the connecting block 211 and are integrally formed with the connecting block 211 through injection molding. The symmetrical arrangement ensures balanced force and avoids jamming or displacement caused by unilateral deformation. The end of the two first elastic arms 212 away from the fixed part 22 is fixedly connected to the connecting block 211, while the end closer to the fixed part 22 is suspended, forming a freely deformable movable end. When the connector 2 is inserted into the socket 111 through the socket 112, the movable ends of the two first elastic arms 212 are squeezed towards the center by the inner wall of the socket 112, allowing the first elastic arms 212 to smoothly enter the socket 111. As the insertion depth increases, the first elastic arms 212 open outwards by their own elastic restoring force, and the end face of the movable end abuts against the inner wall of the socket 111 to form a limiting fit, thereby preventing the connector 2 from coming out and achieving a stable installation.

[0027] In some embodiments of this utility model, the two first elastic arms 212 are respectively provided with a reinforcing part 213 at one end near the fixing part 22. The reinforcing part 213 and the corresponding first elastic arm 212 are integral structures. The connection between the reinforcing part 213 and the first elastic arm 212 forms a limiting step that abuts against and limits the inner wall of the insertion hole 111.

[0028] Specifically, each first elastic arm 212 has a reinforcing part 213 integrally connected to one end near the fixed part 22. The reinforcing part 213 is a local thickening or reinforcement structure of the free end of the first elastic arm 212, and the material is the same as the first elastic arm 212. By setting the reinforcing part 213, the local rigidity and deformation resistance are improved, avoiding plastic deformation, fracture or elastic failure of the free end of the first elastic arm 212 due to excessive pressure, and extending the service life of the elastic connection part 21. A limiting step is formed at the connection between the reinforcing part 213 and the first elastic arm 212. The side of the step facing the inner wall of the socket 111 is the limiting surface. The limiting surface directly abuts against the inner wall of the socket 111 to form a mechanical limit, preventing the connector 2 from coming out of the socket 111 and ensuring a stable connection between the sensor assembly 20 and the electronic control box 10.

[0029] like Figure 5 As shown, in some embodiments of this utility model, the reinforcing part 213 includes a first reinforcing segment 2131 and a second reinforcing segment 2132 connected together. The two ends of the first reinforcing segment 2131 are respectively connected to the first elastic arm 212 and the second reinforcing segment 2132. The distance between the first reinforcing segment 2131 and the end closer to the first elastic arm 212 gradually decreases, while the distance between the second reinforcing segment 2132 and the end closer to the first reinforcing segment 2131 gradually increases.

[0030] Specifically, the distance between the ends of the two first reinforcing segments 2131 closest to the elastic arm is greater than the distance between the ends furthest from the elastic arm. This guides the pressure exerted by the inner wall of the socket 111 on the reinforcing part 213 towards the center, preventing stress from directly acting on the vulnerable area near the elastic arm. Simultaneously, the converging shape provides a transitional basis for the subsequent expansion of the second reinforcing segment 2132, ensuring a smooth structural connection. One end of the second reinforcing segment 2132 is connected to the end of the first reinforcing segment 2131 furthest from the first elastic arm 212, while the other end extends away from the elastic arm. The distance between them gradually increases from the end closest to the first reinforcing segment 2131 to the end furthest from the first reinforcing segment 2131, thus exhibiting an expanding shape. This expanding shape increases the contact area with the inner wall of the socket 111, dispersing the limiting pressure and enhancing the stability of the locking mechanism. The connection between the first reinforcing section 2131 and the second reinforcing section 2132 forms an included angle, which can be in the range of 90°-150°, such as 90°, 100°, 110°, 130°, 150°, etc. The outer side of the included angle engages with the peripheral wall of the socket 111, further improving the fixing strength and installation reliability of the connector 2 in the socket 111.

[0031] In some embodiments of this utility model, a limiting structure is provided between the mounting part 11 and the connecting member 2. The limiting structure includes a limiting part 41 and a mating part 42. One of the mounting part 11 and the connecting member 2 is provided with the limiting part 41, and the other of the mounting part 11 and the connecting member 2 is provided with the mating part 42.

[0032] like Figure 2 and Figure 5 As shown, in this embodiment, the limiting part 41 includes two second elastic arms 411 disposed on the connector 2. The mounting part 11 is provided with baffles 421 on both sides to form a mating part 42. The second elastic arms 411 have elastic deformation capability. One end of the two second elastic arms 411 is connected to each other, and the other end extends in opposite directions. The connection of the two second elastic arms 411 at their close ends makes them a whole that deforms in synergy. When subjected to external force, the two second elastic arms 411 can synchronously retract towards the center or expand in the opposite direction, and achieve adaptive adjustment during the installation process through the deformation capability of the elastic material.

[0033] Furthermore, both second elastic arms 411 are arc-shaped structures and extend in a direction close to the mounting portion 11, which can disperse local stress concentration and avoid fracture or plastic deformation caused by rigid compression. The mounting portion 11 has outward protruding baffles 421 on both sides. The outer surfaces of the two second elastic arms 411 are limiting surfaces that contact the baffles 421. The two baffles 421 are parallel and their inner spacing is adapted to the maximum outward expansion width of the two second elastic arms 411. The gap between the inner sides of the two baffles 421 forms a limiting space 4211.

[0034] When the connector 2 is inserted into the socket 111, the second elastic arm 411 moves with the connector 2 into the limiting space 4211 between the two retaining ribs 421. The sides of the two second elastic arms 411 contact and limit the inner surface of the retaining ribs 421. After the two contact and limit the movement, only the movement (insertion / extraction) along the axial direction of the socket 111 is allowed, which restricts the circumferential rotation of the connector 2 around the central axis of the socket 111. Through the anti-rotation limit, the temperature sensor 3 always maintains the preset detection direction, ensuring that the collected temperature data truly reflects the target ambient temperature and ensuring the accuracy of the environmental data reading. During disassembly, the user can directly hold the ends of the two arc-shaped second elastic arms 411 by hand and apply force in the opposite direction to the bending direction to overcome the elastic restoring force of the elastic arm material, causing it to move in the opposite direction to the bending direction, so that the second elastic arm 411 is higher than the inner surface of the retaining rib 421, thereby releasing the contact limit of the retaining rib 421 on the elastic arm. Then, the connector 2 is rotated at a certain angle towards the socket 112. At this time, the connector 2 can be directly pulled out along the socket 112. No screwdriver or other tools are required throughout the process, making the operation simple and quick, and convenient for maintenance and replacement.

[0035] In other embodiments, the limiting part 41 may also be at least one limiting protrusion provided on the outer wall of the connector 2, and the mating part 42 may be a limiting hole provided on the inner wall of the insertion hole 111 corresponding to the limiting protrusion, with the hole diameter slightly larger than the diameter of the protrusion and the depth matching the height of the protrusion. When the connector 2 is inserted into the insertion hole 111, the limiting protrusion slides in contact with the inner wall of the insertion hole 111; when it moves to the position of the limiting hole, the limiting protrusion is engaged in the limiting hole, and the interference fit between the protrusion and the hole wall restricts the circumferential rotation of the connector 2; when disassembling, an axial tensile force or rotational force needs to be applied to disengage the protrusion from the limiting hole, thereby releasing the limiting.

[0036] The second aspect of this utility model provides an indoor air conditioning unit, which includes a housing and the aforementioned electronic control component 100. The housing includes a front frame and a panel. The panel is located at the front of the front frame, covering and protecting the front surface of the front frame, and can be opened to expose the front surface of the front frame when needed. The front frame has a mounting cavity with an open end, through which the electronic control component 100 is installed. By setting the electronic control component 100 in the indoor air conditioning unit, the mounting part 11 of the electronic control box 10 is provided with a socket 111 and a connector 112 communicating with the socket 111. The connector 2 of the sensor component 20 is quickly inserted into the socket 111 through the connector 112, realizing convenient disassembly and reliable connection between the sensor component 20 and the electronic control box 10, simplifying the sensor 3 installation process, improving assembly efficiency, and ensuring the stable fixation of the sensor 3 and the electronic control board through the connection of the connector 2 and the socket 111, thereby enhancing the overall structural stability and maintenance convenience of the electronic control component 100.

[0037] A third aspect of this utility model provides an air conditioner, including the aforementioned electronic control component 100, or including an indoor unit as described above. The air conditioner may also include an outdoor unit, which includes a compressor, an outdoor heat exchanger, a four-way valve, an expansion valve, etc. The compressor, outdoor heat exchanger, four-way valve, expansion valve, and indoor heat exchanger are connected via refrigerant piping to form a refrigeration / heating system.

[0038] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
