Description

Technical Field

[0001] This application relates to the field of household appliance technology, and more particularly to an indoor unit for an air conditioner. Background Technology

[0002] The field of home appliance technology encompasses a wide range of product categories, including but not limited to refrigerators, washing machines, air conditioners, microwave ovens, dishwashers, and vacuum cleaners. The indoor unit of an air conditioner is the core component responsible for indoor air treatment within an air conditioning system. Through internal components such as evaporators and fans, it achieves heat exchange with indoor air, ultimately providing cooling, heating, or ventilation. It is a key device for regulating indoor temperature and comfort.

[0003] In practical use, air conditioner indoor units are typically operated via physical remote controls or buttons on the unit itself. However, with increasing demand for smart technology, more and more customers are requesting the installation of their own WiFi modules. During installation, the WiFi module's connector must be connected to the corresponding interface on the air conditioner's circuit board to enable remote control via smartphone. However, because different brands and models of WiFi modules vary in size and specifications, the size and shape of the connectors used to connect to the WiFi modules also differ slightly. After the WiFi module is connected to the circuit board, the air conditioner cannot accommodate connectors of different sizes, making the installation and securing of the WiFi module and connector inconvenient. Utility Model Content

[0004] This application discloses an indoor air conditioning unit that uses fasteners to fix a WiFi module and a connector, and can adapt to connectors of different sizes.

[0005] To achieve the above objectives, some embodiments of this application provide an indoor air conditioning unit, comprising: a housing, wherein a circuit board is disposed within the housing; a fixing member is disposed within the housing, the fixing member having an accommodating space; a connecting connector is disposed within the accommodating space, one end of the connecting connector forming an interface, and the other end being electrically connected to the circuit board; a WiFi module is disposed within the accommodating space, the WiFi module having a connecting plug, the connecting plug being inserted into the interface; the fixing member is provided with: a first limiting component abutting against the connecting connector along the thickness direction to restrict the degree of freedom of the connecting connector along its own thickness direction, and the first limiting component is capable of elastic deformation along the thickness direction of the connecting connector; and a second limiting component abutting against the connecting connector along the width direction to restrict the degree of freedom of the connecting connector along its own width direction, and the second limiting component is capable of elastic deformation along the width direction of the connecting connector.

[0006] In this embodiment, a fastener secures the connector. The WiFi module is inserted into the connector plug within the fastener. The first and second limiting components can elastically deform while securing the connector. The elastic deformation of the first limiting component along the thickness direction automatically accommodates thickness deviations in the connector, adjusting the clamping space to prevent over-tightness (inability to install) or over-looseness (causing wobbling). The elastic deformation of the second limiting component along the width direction adapts to width deviations, ensuring stable clamping of connectors of different widths. The same fastener is compatible with multiple connector specifications, improving its versatility and facilitating the installation and securing of the WiFi module and connector within the air conditioner indoor unit.

[0007] As an optional implementation, the fastener includes: a mounting base plate; the connecting joint includes: a first surface facing away from the mounting base plate and a second surface facing the mounting base plate; the first limiting component includes: a first limiting member connected to the mounting base plate, the first limiting member being able to abut against the first surface and being able to elastically deform along the thickness direction of the connecting joint.

[0008] Thus, the elastic deformation capability of the first limiting member along the thickness direction of the connecting joint provides adaptive space for connecting joints of different thicknesses. When the joint thickness is slightly thicker, the first limiting member can elastically deform away from the mounting base plate, reserving space for the joint; when the joint thickness is slightly thinner, its elastic restoring force can maintain tight contact with the first surface, preventing gaps and wobbling in the joint in the thickness direction. This design ensures that the fastener can accommodate and fix connecting joints of different thicknesses.

[0009] As an optional implementation, the first limiting member includes two limiting buckles spaced apart along the width direction of the connecting joint. Each limiting buckle includes: a connecting part connected to the mounting base plate; and an abutting part connected to the end of the connecting part away from the mounting base plate. The abutting part is capable of elastic deformation along the thickness direction of the connecting joint.

[0010] Thus, the two clips distributed along the width of the connector can symmetrically abut against the first surface of the connector from both sides, avoiding uneven force distribution and ensuring that the connector is stably clamped in the thickness direction, further improving the reliability of the fixation.

[0011] The connecting part is fixed to the mounting base plate, providing stable support for the overall structure. The abutment part, as the part directly in contact with the connecting joint, can independently undergo elastic deformation along the thickness direction, ensuring the accuracy of deformation (only in the thickness direction) and preventing deformation of the connecting part from affecting the overall structural stability. When there are slight differences in the thickness of the connecting joint, the abutment part can adaptively adjust through its own deformation, while the connecting part provides stable support, ensuring sufficient clamping force while being compatible with dimensional differences of the connecting joint within 2mm. The limiting buckle structure is simple and can be integrally molded with the mounting base plate (e.g., through injection molding), reducing production difficulty. The two spaced buckles reduce material usage and provide operating space for the installation of the connecting joint, allowing installers to quickly place the joint into the receiving space and complete positioning, improving assembly efficiency.

[0012] As an optional implementation, the first limiting component further includes: a second limiting member disposed on the mounting base plate and spaced apart from the abutting portion along the thickness direction of the connecting joint. The second limiting member can abut against the second surface and can elastically deform along the thickness direction of the connecting joint. In its natural state, the minimum distance between the first limiting member and the abutting portion along the thickness direction of the connecting joint is less than the thickness of the connecting joint.

[0013] Thus, the first limiting member applies pressure from the first side of the connecting joint, while the second limiting member provides reverse support from the second side, forming a clamping force along the thickness direction. When there is a dimensional difference of less than 2mm in thickness between the connecting joints, the bidirectional elastic deformation can maintain a tight contact with the connecting joint through the yielding or tightening of the first limiting member and the pushing or buffering of the second limiting member, limiting its displacement in the thickness direction. It can also resist vibration and prevent poor contact caused by joint shaking.

[0014] Secondly, by ensuring the minimum distance between the two limiting members is less than the joint thickness under natural conditions, the stability of the preload is guaranteed. Before assembly, the distance between the first and second limiting members is already less than the joint thickness. During installation, the elastic deformation of both members expands the space along the thickness direction to accommodate the connecting joint. After assembly, the restoring force generated by the deformation continuously provides the clamping preload. Regardless of whether the joint is slightly thicker or thinner, sufficient clamping force can be maintained through bidirectional elastic adjustment, ensuring compatibility with joints of different specifications.

[0015] As an optional implementation, the mounting base plate is provided with two clearance grooves spaced apart along the width direction of the connecting joint. The clearance grooves penetrate the mounting base plate and extend along the length direction of the connecting joint. The mounting base plate between the two clearance grooves is bent in the direction from the mounting base plate to the accommodating space to form the second limiting member, so that the second limiting member can elastically deform along the thickness direction of the connecting joint. The surface of the second limiting member that abuts against the second surface is the abutting surface, and the abutting surface is correspondingly arranged with the first limiting member along the thickness direction of the connecting joint.

[0016] Two clearance grooves spaced apart along the width of the connecting joint on the mounting base plate provide space for the deformation of the second limiting member. When there are differences in the thickness of the connecting joint, the second limiting member can deform freely along the thickness direction. The clearance grooves prevent other parts of the mounting base plate from obstructing its deformation, ensuring that deformation only occurs in the area in contact with the second surface of the connecting joint, thus adapting to thickness deviations of different connecting joints. At the same time, the abutment surface formed by bending corresponds to the first limiting member along the thickness direction, ensuring the symmetry of the bidirectional clamping force and preventing the connecting joint from tilting due to force offset.

[0017] Secondly, the integrated molding structure of the second limiting component and the mounting base plate enhances the structural strength and stability of the second limiting component. The second limiting component is formed by directly bending the mounting base plate, reducing the number of parts and assembly steps, lowering production and maintenance costs, and avoiding the connection loosening problems that may occur with split structures. This design allows the second limiting component and the mounting base plate to form a stable whole, making it less prone to breakage or displacement even under long-term elastic deformation recovery forces, ensuring support for the connecting joint. Furthermore, the clearance groove optimizes the utilization of installation space. The clearance groove penetrates the mounting base plate and extends along the length of the connecting joint, without occupying additional accommodating space, and its hollow structure forms a second limiting component capable of elastic deformation.

[0018] As an optional implementation, the fastener includes: a mounting base plate; the second limiting component includes two first limiting ribs disposed opposite each other along the width direction of the connecting joint, the first limiting ribs extending along the length direction of the connecting joint, the connecting plug being able to be inserted between the two first limiting ribs along the length direction of the connecting joint, and the first limiting ribs being able to elastically deform along the width direction of the connecting joint so that the first limiting ribs can be interference-fitted with the connecting joint.

[0019] Thus, the two opposing first limiting ribs form a symmetrical constraint on the connecting joint along its width, improving the clamping stability of the connecting joint. The first limiting ribs extend along the length of the connecting joint, and their length matches the length of the connecting joint, allowing for full-length abutment from both sides in the width direction, ensuring that even large connecting joints can be clamped at various positions in the width direction. The elastic deformation of the first limiting ribs along the width direction accommodates slight differences in the joint width. When the joint width is slightly wider, the ribs can elastically recoil outwards, accommodating the joint through deformation, thus improving the versatility of the fastener.

[0020] Furthermore, the structure of the retaining ribs extending along the length direction provides a guiding function for the insertion and removal of the connector. When the connector is inserted between the two retaining ribs along the length direction, the parallel extension structure of the retaining ribs can guide the connector into place and abut against the first limiting component.

[0021] As an optional implementation, the connecting joint includes: a first surface, which is the side of the connecting joint facing away from the mounting base plate, and a second surface, which is the side of the connecting joint facing the mounting base plate; the first limiting component includes: a first limiting member connected to the first limiting rib, the first limiting member being able to abut against the first surface and being able to elastically deform along the thickness direction of the connecting joint, the first limiting member and the first limiting rib being integrally formed.

[0022] Thus, the integral molding of the first limiting component and the first limiting rib enhances the overall integrity and stability of the fastener structure, avoiding connection gaps or loosening that may occur with separate assembly. The elastic deformation of the first limiting component along its thickness and the elastic deformation of the first limiting rib along its width, through the same base material, allow for synchronous adaptive adjustment of deformation in both directions when there are slight differences in thickness and width at the connection joint. This ensures that the overall clamping force remains balanced, further guaranteeing compatibility with connection joints of different sizes. Integral molding (such as injection molding or stamping) eliminates the need for separate machining of the first limiting component and the first limiting rib, reducing the number of parts and assembly steps, and improving production efficiency.

[0023] As an optional implementation, each of the first limiting ribs has a guide rib at one end. Along the width direction of the connecting joint, the end of the guide rib away from the first limiting rib is inclined away from the connecting joint to guide the connecting plug to be inserted between the two first limiting ribs.

[0024] In this way, the inclined guide ribs can automatically align the connector with the gap between the two first limiting ribs by guiding the connector through the slope. Even if there is a slight deviation in the position of the connector during installation, it can still be installed in place under the smooth guidance of the guide ribs, improving assembly efficiency. Secondly, the guiding effect indirectly protects the structural integrity of the connector and interface. By pre-guiding the insertion direction of the connector, the guide ribs ensure that it is inserted parallel to the extension direction of the ribs, avoiding physical damage to the connector caused by oblique or forced insertion, extending the service life of the connector, and ensuring the long-term reliability of the electrical connection.

[0025] As an optional implementation, the fastener further includes a first sidewall and a second sidewall disposed opposite to each other along the length direction of the connector. The fastener also includes a second limiting rib disposed opposite to the first sidewall along the length direction of the connector to limit the position of the connector plug along the length direction of the connector. The WiFi module is disposed between the second limiting rib and the second sidewall.

[0026] Thus, through the cooperation of the second limiting rib and the first sidewall, a limiting position is formed along the length of the connecting joint. The WiFi module's connector plug is inserted into the interface of the connecting joint and fixed in place. The second limiting rib clearly defines the installation area of ​​the WiFi module (between the second limiting rib and the second sidewall), achieving an orderly component layout, providing an independent accommodating space for the WiFi module, and improving the overall structural regularity. The length-direction limiting, in conjunction with the thickness and width-direction limiting of the connecting joint, strengthens the overall limiting effect of the fastener.

[0027] As an optional implementation, the housing has a receiving cavity, and the housing includes: a front panel, the front panel having a positioning groove on the side facing the receiving cavity, a positioning element at one end of the fastener along the length direction of the connecting joint, the positioning element being able to be inserted into the positioning groove to define the position of the fastener on the front panel; the fastener having a first positioning hole, the first positioning hole being disposed near the end of the fastener along the length direction of the connecting joint away from the positioning element, the front panel having a second positioning hole, and the air conditioner indoor unit further including a fastener, the fastener being disposed through the first positioning hole and the second positioning hole to connect the fastener and the front panel.

[0028] In this way, the insertion and engagement of the positioning component and the positioning slot provides initial constraint on the fixing component from one end, quickly determining the lateral and longitudinal position of the fixing component on the front panel and preventing positional deviation during installation. Fasteners are then inserted through the first and second positioning holes (near the other end of the fixing component) for tightening, forming a stable structure with one end positioned and the other fixed, ensuring the relative position of the fixing component and the front panel is fixed. This connection method balances assembly efficiency and structural stability. The insertion design of the positioning component and the positioning slot can serve as pre-fixation during assembly, facilitating subsequent fastener installation and reducing assembly time. Furthermore, when it is necessary to inspect or replace the WiFi module or connector, the fixing component can be removed simply by disassembling the fasteners and pulling out the positioning component, without damaging the casing or other structures, simplifying the maintenance process.

[0029] Compared with the prior art, the beneficial effects of this application are at least as follows: The air conditioner indoor unit provided in this application embodiment uses a fastener to fix the connector, and the WiFi module is plugged into the connector. The first and second limiting components can elastically deform while fixing the connector. The elastic deformation of the first limiting component along the thickness direction automatically accommodates the connector's thickness deviation, adjusting the clamping space through deformation to prevent excessive tightness (making installation impossible) or excessive looseness (causing wobbling). The elastic deformation of the second limiting component along the width direction adapts to width deviations, ensuring that connectors of different widths can be stably clamped. The same fastener is compatible with multiple connector specifications, improving the fastener's versatility and facilitating the installation and fixation of the WiFi module and connector within the air conditioner indoor unit.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0038] The field of home appliance technology encompasses a wide range of product categories, including but not limited to refrigerators, washing machines, air conditioners, microwave ovens, dishwashers, and vacuum cleaners. The indoor unit of an air conditioner is the core component responsible for indoor air treatment within an air conditioning system. Through internal components such as evaporators and fans, it achieves heat exchange with indoor air, ultimately providing cooling, heating, or ventilation. It is a key device for regulating indoor temperature and comfort.

[0039] In practical use, air conditioner indoor units are typically operated via physical remote controls or buttons on the unit itself. However, with increasing demand for smart technology, more and more customers are requesting the installation of their own WiFi modules. During installation, the WiFi module's connector must be connected to the corresponding interface on the air conditioner's circuit board to enable remote control via smartphone. However, due to the varying sizes and specifications of different brands and models of WiFi modules, the size and shape of the connectors used to connect to them also differ slightly. After the WiFi module is connected to the circuit board, the air conditioner cannot accommodate connectors of different sizes, making the installation and securing of both the WiFi module and the connector inconvenient.

[0040] Based on this, the present application provides an indoor air conditioning unit that uses fasteners to fix a WiFi module and a connector. The first limiting component and the second limiting component can elastically deform while fixing the connector to adapt to connectors of different sizes.

[0041] The present technical solution will be further described below with reference to the embodiments and accompanying drawings.

[0042] Please see Figures 1 to 3 , Figure 1 This is a schematic diagram of the structure of the air conditioner indoor unit 100 disclosed in the embodiments of this application. Figure 2 This is a schematic diagram of the open front panel 11 of the air conditioner indoor unit 100 disclosed in this application embodiment. Figure 3 This is a schematic diagram of the WiFi module 5 installed on the front panel 11 as disclosed in this application embodiment. This application embodiment provides an air conditioner indoor unit 100. The fan inside the indoor unit draws in indoor air. The air first passes through a filter to remove dust and other impurities, and then flows through the evaporator. At this time, the low-temperature, low-pressure refrigerant delivered by the outdoor unit of the air conditioner evaporates and absorbs heat in the evaporator, absorbing the heat of the air flowing through it, thus lowering the air temperature. Finally, the cooled air is blown back into the room by the fan, and the condensate produced by the evaporator is discharged through the drain pipe. This cycle repeats to achieve indoor cooling. The principle is similar when heating, using the refrigerant to condense and release heat to heat the air.

[0043] The indoor unit 100 of the air conditioner includes a casing 1, which is the basic frame of the indoor unit 100. The casing 1 forms an internal space to provide an installation carrier and protection for other components (circuit board 2, fasteners 3, etc.), while isolating the internal structure from the external environment to ensure the safe operation of the equipment. The casing 1 is provided with an air inlet and an air outlet.

[0044] In some embodiments, the wall-mounted air conditioner indoor unit 100 includes a heat exchanger, which is the core component for realizing air heat exchange. The heat exchanger is used to exchange heat with the airflow flowing through the air inlet of the casing 1. When the air conditioner is cooling, the low-temperature refrigerant flowing in the heat exchanger absorbs the heat in the airflow and cools the air. When heating, the high-temperature refrigerant releases heat to the airflow and warms the air.

[0045] In some implementations, the wall-mounted air conditioner indoor unit 100 also includes a fan, located inside the casing 1, which is the power source for air circulation. The fan generates suction by rotating, drawing indoor air into the casing 1 through the air inlet. After heat exchange in the heat exchanger, the drawn-in air is pushed into the air duct assembly by the fan and finally delivered into the room through the air outlet of the casing 1, completing the indoor air circulation and temperature regulation process. The operation of the fan is crucial for achieving airflow and heat exchange circulation; its power and operating efficiency directly affect the cooling or heating effect and air volume of the air conditioner.

[0046] In some embodiments, the air conditioner indoor unit 100 also includes a display module 6, which is mainly used to display the operating status of the air conditioner (such as temperature, mode, network status, etc.) and serves as a window for users to intuitively understand the status of the equipment.

[0047] In some embodiments, combined with Figures 3 to 5 , Figure 4 This is a schematic diagram of the structure of the front panel 11 disclosed in an embodiment of this application. Figure 5 This is a schematic diagram of the WiFi module 5 connected to the display module 6 as disclosed in an embodiment of this application. The air conditioner indoor unit 100 includes a circuit board 2, which is disposed inside the housing 1. The circuit board 2 can be a main control board or a circuit board inside the display module 6 (e.g., Figure 5 The main control board is the control core of the indoor unit 100 of the air conditioner, responsible for receiving commands and regulating the operating status (such as cooling, heating, and fan speed adjustment). After the connector 4 is electrically connected to the circuit board 2, the signal from the WiFi module 5 can be transmitted to the circuit board 2 to realize the reception and execution of remote control commands. When the connector 4 is electrically connected to the main control board through the circuit board 2 connected to the display module 6, the WiFi module 5 receives the command and transmits it to the display module 6. At the same time, the display module 6 forwards the command to the main control board (to drive the compressor, fan, and other actuators).

[0048] In some embodiments, the indoor unit 100 of the air conditioner further includes a connector 4 and a WiFi module 5. The connector 4 is disposed in the accommodating space 3a. One end of the connector 4 forms an interface 4a, and the other end is electrically connected to the circuit board 2. The WiFi module 5 is disposed in the accommodating space 3a. The WiFi module 5 has a connector plug 51, which is plugged into the interface 4a.

[0049] In some embodiments, combined with Figures 6 to 9 , Figure 6 This is a first-view structural diagram of the WiFi module 5 and connector 4 installed in the fixing member 3, as disclosed in the embodiments of this application. Figure 7 This is a second-view structural diagram of the WiFi module 5 and connector 4 installed within the fixing member 3, as disclosed in an embodiment of this application. Figure 8 for Figure 7 Sectional view at point AA. Figure 9 This is a structural schematic diagram of the fastener 3 disclosed in the embodiments of this application from a first perspective. The air conditioner indoor unit 100 also includes the fastener 3. The fastener 3 is provided with a first limiting component 31 and a second limiting component 32. The first limiting component 31 abuts against the connecting joint 4 along the thickness direction X to limit the degree of freedom of the connecting joint 4 along its own thickness direction, and the first limiting component 31 can undergo elastic deformation along the thickness direction X of the connecting joint 4. The second limiting component 32 abuts against the connecting joint 4 along the width direction Y to limit the degree of freedom of the connecting joint 4 along its own width direction, and the second limiting component 32 can undergo elastic deformation along the width direction Y of the connecting joint 4.

[0050] When users purchase WiFi module 5 and the connector that connects to it, the connector is usually of standard size. The shell of connector 4 may have a manufacturing error of less than 2mm, resulting in slight size differences between different connectors 4.

[0051] In this embodiment, the connector 4 is fixed in place by the fastener 3. The WiFi module 5 is inserted into the connector plug 51 within the fastener 3. The first limiting component 31 and the second limiting component 32 can elastically deform while fixing the connector 4. The elastic deformation of the first limiting component 31 along the thickness direction can automatically accommodate the thickness deviation of the connector, adjusting the clamping space through deformation to avoid being too tight for installation or too loose for shaking. The elastic deformation of the second limiting component 32 along the width direction adapts to width deviations, ensuring that connectors of different widths can be stably clamped. The same fastener 3 is compatible with multiple specifications of connectors 4, improving the versatility of the fastener 3 and facilitating the installation and fixation of the WiFi module 5 and connector 4 within the air conditioner indoor unit 100.

[0052] During installation, there is no need to precisely calibrate the dimensions of the connector and the fastener 3. Simply place the connector into the accommodating space 3a. For example, when the size of the connector 4 is large, the first limiting component 31 and the second limiting component 32 can automatically position and fix the connector 4 through elastic deformation, reducing assembly difficulty and improving assembly efficiency.

[0053] The interface 4a of the connector 4 can be a USB (Universal Serial Bus) interface 4a, or an SDIO (Secure Digital Input Output) interface 4a, etc. This embodiment does not limit this. For ease of explanation, the attached drawings use a USB connector as an example for illustration.

[0054] In some embodiments, combined with Figure 8 , Figure 9 and Figure 13 , Figure 13 This is a schematic diagram of the structure of the USB connector disclosed in the embodiments of this application. The fixing member 3 includes a mounting base plate 33, and the connecting connector 4 includes a first surface 41 and a second surface 42 that are opposite to each other along its own thickness direction. The first surface 41 is the side of the connecting connector 4 that is away from the mounting base plate 33, and the second surface 42 is the side of the connecting connector 4 that faces the mounting base plate 33. The first limiting component 31 includes a first limiting member 311 that is connected to the mounting base plate 33. The first limiting member 311 can abut against the first surface 41 and can undergo elastic deformation along the thickness direction X of the connecting connector 4. The first limiting member 311 is always in an interference fit with the connecting connector 4.

[0055] The elastic deformation capability of the first limiting member 311 along the thickness direction of the connecting joint 4 provides adaptive space for connecting joints 4 of different thicknesses. When the joint thickness is slightly thicker, the first limiting member 311 can elastically deform away from the mounting base plate 33, reserving space for the joint; when the joint thickness is slightly thinner, its elastic restoring force can maintain tight contact with the first surface 41, preventing gaps and wobbling in the joint in the thickness direction. This design ensures that the fixing member 3 can accommodate and fix connecting joints 4 of different thicknesses.

[0056] It is understandable that the second surface 42 of the connecting joint 4 can abut against the mounting base plate 33, or abut against other structures, and cooperate with the first limiting member 311 to clamp the connecting joint 4 together, limiting the degree of freedom of the connecting head in the reverse direction along its own thickness.

[0057] In some embodiments, combined with Figures 9 to 13 , Figure 10 This is a schematic diagram of the fastener 3 disclosed in the embodiments of this application from a second perspective. Figure 11 for Figure 10 Sectional view at point BB. Figure 12This is a schematic diagram of the structure of the first limiting member 311 disclosed in the embodiment of this application. The first limiting member 311 includes two limiting buckles 3111 spaced apart along the width direction Y of the connecting joint 4. The limiting buckle 3111 includes a connecting part 31111 and an abutting part 31112. The connecting part 31111 is connected to the mounting base plate 33, and the abutting part 31112 is connected to the end of the connecting part 31111 away from the mounting base plate 33. The abutting part 31112 can undergo elastic deformation along the thickness direction X of the connecting joint 4.

[0058] The two buckles distributed along the width of the connector 4 can form symmetrical abutments against the first surface 41 of the connector 4 from both sides, avoiding uneven force distribution and ensuring that the connector 4 is stably clamped in the thickness direction, further improving the reliability of the fixation.

[0059] The connecting part 31111 is fixed to the mounting base plate 33, providing stable support for the overall structure. The abutting part 31112, as the part that directly contacts the connecting joint 4, can independently undergo elastic deformation along the thickness direction, ensuring the accuracy of the deformation (only in the thickness direction) and preventing the connecting part 31111 from being deformed under force and affecting the overall structural stability. When there is a slight difference in the thickness of the connecting joint 4, the abutting part 31112 can adaptively adjust through its own deformation, while the connecting part 31111 provides stable support, ensuring that sufficient clamping force is always maintained while being compatible with dimensional differences of the connecting joint 4 within 2mm.

[0060] The limiting buckle 3111 has a simple structure and can be integrally molded with the mounting base plate 33 (such as injection molding process), reducing production difficulty; the two buckles set at intervals not only reduce the amount of material used, but also reserve operating space for the installation of the connecting joint 4, making it convenient for installers to quickly put the joint into the accommodating space 3a and complete the positioning, thus improving assembly efficiency.

[0061] Optionally, the connecting part 31111 and the abutting part 31112 are integrally formed, which can enhance the rigidity and stability of the limiting buckle 3111 structure and prevent the connection between the two from loosening or breaking due to long-term stress or vibration; at the same time, it eliminates the assembly process, reduces production complexity and cost, and ensures that the elastic deformation direction of the abutting part 31112 is more precise and controllable, thereby improving the limiting reliability of the connecting joint 4.

[0062] In some embodiments, combined with Figure 8 , Figure 10 , Figure 11 and Figure 13The first limiting component 31 also includes a second limiting member 312. The second limiting member 312 is disposed on the mounting base plate 33 and is spaced apart from the abutment portion 31112 along the thickness direction X of the connecting joint 4. The second limiting member 312 can abut against the second surface 42 and can undergo elastic deformation along the thickness direction X of the connecting joint 4. In its natural state, the minimum distance between the first limiting member 311 and the abutment portion 31112 along the thickness direction X of the connecting joint 4 is less than the thickness of the connecting joint 4.

[0063] The first limiting member 311 applies pressure from the first surface 41 of the connecting joint 4, and the second limiting member 312 provides reverse support from the second surface 42. The two form a clamping force along the thickness direction. When there is a dimensional difference of less than 2 mm in thickness between the connecting joint 4 and the connecting joint 4, the bidirectional elastic deformation can maintain a tight contact with the connecting joint 4 through the yielding or tightening of the first limiting member 311 and the pushing or buffering of the second limiting member 312, limiting its displacement in the thickness direction, and also resisting vibration to prevent poor contact caused by shaking of the joint.

[0064] Secondly, by ensuring that the minimum distance between the two parts in their natural state is less than the joint thickness, the stability of the preload is guaranteed. Before assembly, the distance between the first limiting member 311 and the second limiting member 312 is already less than the joint thickness. During installation, the elastic deformation of both parts is used to expand the space along the thickness direction to accommodate the connecting joint 4. After assembly, the restoring force generated by the deformation will continuously provide the clamping preload. Regardless of whether the joint is slightly thicker or thinner, sufficient clamping force can be maintained through bidirectional elastic adjustment, ensuring compatibility with joints of different specifications.

[0065] The second limiting member 312 can be a structure that is independently set on the mounting base plate 33, or it can be a part of the mounting base plate 33. This embodiment does not limit it in this way.

[0066] In some embodiments, combined with Figure 8 , Figure 10 , Figure 11 and Figure 13 The mounting base plate 33 is provided with two clearance grooves 33a spaced apart along the width direction Y of the connecting joint 4. The clearance grooves 33a penetrate the mounting base plate 33 and extend along the length direction Z of the connecting joint 4. The mounting base plate 33 between the two clearance grooves 33a is bent in the direction from the mounting base plate 33 to the accommodating space 3a to form a second limiting member 312, so that the second limiting member 312 can elastically deform along the thickness direction X of the connecting joint 4. The surface of the second limiting member 312 that abuts against the second surface 42 is the abutting surface 3121. The abutting surface 3121 is provided in accordance with the first limiting member 311 along the thickness direction X of the connecting joint 4.

[0067] Two clearance grooves 33a spaced apart along the width direction of the connecting joint 4 on the mounting base plate 33 provide space for the deformation of the second limiting member 312. When there is a difference in the thickness of the connecting joint 4, the second limiting member 312 can deform freely along the thickness direction. The clearance grooves 33a can avoid the obstruction of its deformation by other parts of the mounting base plate 33, ensuring that the deformation only occurs in the area in contact with the second surface 42 of the connecting joint 4, thereby adapting to the thickness deviation of different connecting joints 4. At the same time, the abutment surface 3121 formed by bending corresponds to the first limiting member 311 along the thickness direction, ensuring the symmetry of the bidirectional clamping force and preventing the connecting joint 4 from tilting due to force offset.

[0068] Secondly, the integral molding structure of the second limiting member 312 and the mounting base plate 33 enhances the structural strength and stability of the second limiting member 312. The second limiting member 312 is formed by directly bending the mounting base plate 33, which reduces the number of parts and assembly steps, lowering production and maintenance costs, and avoiding the loosening problems that may occur with split structures. This design allows the second limiting member 312 and the mounting base plate 33 to form a stable whole, making it less prone to breakage or displacement even under long-term elastic deformation recovery forces, thus ensuring support for the connecting joint 4.

[0069] Furthermore, the clearance groove 33a optimizes the utilization of the installation space. The clearance groove 33a penetrates the mounting base plate 33 and extends along the length of the connecting joint 4, without occupying additional accommodating space 3a, and can form a second limiting member 312 that can elastically deform through the hollow structure.

[0070] In some embodiments, combined with Figure 9 and Figure 10 The fastener 3 includes a mounting base plate 33; the second limiting component 32 includes two first limiting ribs 321 arranged opposite each other along the width direction Y of the connecting joint 4. The first limiting ribs 321 extend along the length direction Z of the connecting joint 4. The connecting plug 51 can be inserted between the two first limiting ribs 321 along the length direction Z of the connecting joint 4. The first limiting ribs 321 can undergo elastic deformation along the width direction Y of the connecting joint 4 so that the first limiting ribs 321 can be interference-fitted with the connecting joint 4.

[0071] Two opposing first limiting ribs 321 form a symmetrical constraint on the connecting joint 4 along the width direction Y, improving the clamping stability of the connecting joint 4. The first limiting ribs 321 extend along the length direction of the connecting joint 4, and their length is adapted to the length of the connecting joint 4, enabling them to abut against the entire joint from both sides in the width direction, ensuring that even large connecting joints 4 can be abutted and clamped at various positions in the width direction. The elastic deformation of the first limiting ribs 321 along the width direction accommodates slight differences in the joint width. When the joint width is slightly wider, the ribs can elastically recoil outwards, accommodating the joint through deformation, thus improving the versatility of the fastener 3.

[0072] Furthermore, the structure of the retaining ribs extending along the length direction provides a guiding function for the insertion and removal of the connector 51. When the connector 51 is inserted between the two retaining ribs along the length direction, the parallel extension structure of the retaining ribs can guide the connector into place and abut against the first limiting component 31.

[0073] It should be noted that for the connecting joint 4 with a larger width, the first limiting rib 321 and the connecting joint 4 are interference fit. For the connecting joint 4 with a smaller width, there may be a gap between the first limiting rib 321 and the connecting clamp. Under the bidirectional abutment action of the first limiting component 31, the connecting joint 4 will not shift.

[0074] Understandably, in a natural state, the combination Figure 8 The abutting surface 3121 of the second limiting member 312 is higher than the mounting base plate 33 (closer to the connecting joint 4), which can raise the connecting joint 4 so that when the connecting joint 4 is interference-fitted with the first limiting rib 321, it can abut against the part of the first limiting rib 321 away from the mounting base plate 33 along the thickness direction X of the connecting joint 4. Since the first limiting rib 321 has better elastic deformation ability away from the position where it is connected to the mounting base plate 33, it can better adapt to connecting joints 4 of different widths.

[0075] In some embodiments, combined with Figure 9 and Figure 11 The connecting joint 4 includes a first surface 41 and a second surface 42 facing each other along its own thickness direction. The first surface 41 is the side of the connecting joint 4 facing away from the mounting base plate 33, and the second surface 42 is the side of the connecting joint 4 facing the mounting base plate 33. The first limiting component 31 includes a first limiting member 311 connected to a first limiting rib 321. The first limiting member 311 can abut against the first surface 41 and can elastically deform along the thickness direction X of the connecting joint 4. The first limiting member 311 and the first limiting rib 321 are integrally formed.

[0076] The first limiting component 311 and the first limiting rib 321 are integrally formed, which strengthens the overall structure and stability of the fixing component 3 and avoids the connection gaps or loosening that may occur during separate assembly.

[0077] The elastic deformation of the first limiting member 311 along the thickness direction and the elastic deformation of the first limiting rib 321 along the width direction, through the force transmission of the same base, allow the deformation in both directions to be synchronously and adaptively adjusted when there are slight differences in thickness and width of the connecting joint 4, ensuring that the overall clamping force is always balanced, and further guaranteeing the compatibility with connecting joints 4 of different sizes.

[0078] One-piece molding (such as injection molding or stamping) eliminates the need for separate processing of the first limiting part 311 and the first limiting rib 321, reducing the number of parts and assembly steps and improving production efficiency.

[0079] In some embodiments, combined with Figure 9 and Figure 10 Each of the first limiting ribs 321 has a guide rib 34 at one end. Along the width direction Y of the connecting joint 4, the end of the guide rib 34 away from the first limiting rib 321 is inclined away from the connecting joint 4 to guide the connecting plug 51 to be inserted between the two first limiting ribs 321. The fixing member 3 also includes a first sidewall 35 and a second sidewall 36 arranged opposite each other along the length direction Z of the connecting joint 4. One end of the first limiting rib 321 is connected to the first sidewall 35, and the other end is connected to the guide rib 34.

[0080] The inclined guide rib 34 can automatically align the connecting joint 4 with the gap between the two first limit ribs 321 through the slope guide. Even if there is a slight deviation in the position of the connecting joint 4 during installation, it can be installed in place under the smooth guidance of the guide rib 34, which improves the assembly efficiency.

[0081] Secondly, the guiding function indirectly protects the structural integrity of the connector 51 and the interface 4a. The guide rib 34 guides the insertion direction of the connector in advance, ensuring that it is inserted parallel to the extension direction of the guide rib, avoiding physical damage to the connector 4 caused by oblique or hard insertion, extending the service life of the connector 4, and ensuring the long-term reliability of the electrical connection.

[0082] Optionally, the guide rib 34 and the first limiting stop rib 321 are integrally formed.

[0083] Optionally, one end of the connector 4 has an interface 4a, which is plugged into the connector plug 51 of the WiFi module 5, and the other end has a connecting wire 43 for electrical connection with the circuit board 2. The first side wall 35 is provided with a wire outlet hole 35a. Along the width direction Y of the connector 4, the wire outlet hole 35a is located between two first limiting ribs 321 so that the connecting wire 43 of the connector 4 can pass through.

[0084] In some embodiments, combined with Figure 6 , Figure 9 , Figure 10 and Figure 14 , Figure 14 This is a schematic diagram of the structure of the USB flash drive-type WiFi module 5 disclosed in this application embodiment. The fixing member 3 also includes a first sidewall 35 and a second sidewall 36 that are disposed opposite to each other along the length direction Z of the connecting joint 4. The fixing member 3 also has a second limiting rib 37, which is disposed opposite to the first sidewall 35 along the length direction Z of the connecting joint 4 to limit the position of the connecting plug 51 along the length direction Z of the connecting joint 4. The WiFi module 5 is disposed between the second limiting rib 37 and the second sidewall 36. The distance between the first sidewall 35 and the second limiting rib 37 is slightly greater than the length of the connecting joint 4. Specifically, there are two second limiting ribs 37, which are spaced apart along the width direction Y of the connecting joint 4. The connecting plug 51 of the WiFi module 5 can pass between the two second limiting ribs 37 and be inserted into the connecting joint 4.

[0085] The second limiting rib 37, in cooperation with the first sidewall 35, forms a limiting position along the length of the connecting joint 4. The connector plug 51 of the WiFi module 5 is inserted into the interface 4a of the connecting joint 4 and fixed. The second limiting rib 37 clearly defines the installation area of ​​the WiFi module 5 (between the second limiting rib 37 and the second sidewall 36), achieving an orderly component layout, providing an independent installation space for the WiFi module 5, and improving the overall structural regularity. The length-direction limiting, in conjunction with the thickness and width-direction limiting of the connecting joint 4, strengthens the overall limiting effect of the fixing member 3.

[0086] It should be noted that, in combination Figure 8 The side of the second limiting rib 37 away from the mounting base plate 33 must be lower than the edge of the interface 4a of the connecting connector 4 near the mounting base plate 33 to ensure that the second limiting rib 37 will not block the interface 4a and to ensure that the connecting plug 51 of the WiFi module 5 can be plugged into the interface 4a.

[0087] In some embodiments, combined with Figure 3 and Figure 4 The housing 1 has a receiving cavity 1a. The housing 1 includes a front panel 11. A limiting member is provided on the side of the front panel 11 facing the receiving cavity 1a. A positioning groove 11a is formed inside the limiting member. A positioning member 38 is provided at one end of the fixing member 3 along the length direction Z of the connecting joint 4. The positioning member 38 can be inserted into the positioning groove 11a to limit the position of the fixing member 3 on the front panel 11.

[0088] In some embodiments, the fastener 3 is provided with a first positioning hole 33b, which is located near the end of the fastener 3 away from the positioning member 38 along the length direction Z of the connecting joint 4. The front panel 11 is provided with a second positioning hole 11b. The air conditioner indoor unit 100 also includes a fastener, which passes through the first positioning hole 33b and the second positioning hole 11b to connect the fastener 3 and the front panel 11.

[0089] The insertion and engagement of the positioning component 38 with the positioning groove 11a forms an initial limiting constraint on the fixing component 3 from one end, quickly determining the lateral and longitudinal positions of the fixing component 3 on the front panel 11, avoiding positional deviation during installation. Then, fasteners are inserted through the first and second positioning holes 11b (near the other end of the fixing component 3) for fastening, forming a stable structure with one end positioned and the other end fixed, ensuring that the relative position of the fixing component 3 and the front panel 11 is fixed.

[0090] This connection method balances assembly efficiency and structural stability. The insertion design of the positioning component 38 and the positioning groove 11a can serve as a pre-fixation during assembly, facilitating the subsequent installation of fasteners and reducing assembly time. Furthermore, when it is necessary to inspect or replace the WiFi module 5 or the connector 4, the fixing component 3 can be removed simply by disassembling the fasteners and pulling out the positioning component 38, without damaging the housing 1 or other structures, thus simplifying the maintenance process.

[0091] The fastener can be a screw, and the first positioning hole 33b and the second positioning hole 11b are provided with threads, which are used to achieve fastening. The fastener can also be a pin, which is inserted into the positioning hole to achieve limiting and fixing. This embodiment does not limit the fastener to this.

[0092] It is understandable that the fixing method of the display module 6 is similar to the installation and fixing method of the fastener 3, that is, one end is inserted into the positioning groove 11a and the other end is locked with the fastener. This will not be described in detail here.

[0093] It should be noted that, in order to accommodate WiFi modules 5 of different sizes, the dimensions (length, width, and thickness) of the fastener 3 should be larger than the dimensions (length, width, and thickness) of the WiFi module 5.

[0094] For example, the length of the WiFi module 5 typically does not exceed 75mm, the width does not exceed 35mm, and the thickness does not exceed 15mm. Therefore, the length of the accommodating space 3a of the fastener 3 needs to be greater than the sum of the length of the WiFi module 5 and the length of the connecting connector 4, the width of the accommodating space 3a of the fastener 3 needs to be greater than the width of the WiFi module 5 (i.e., greater than 35mm), and the width of the accommodating space 3a of the fastener 3 needs to be greater than the thickness of the WiFi module 5 (i.e., greater than 15mm).

[0095] It should be noted that, in combination Figure 9, Figure 13 and Figure 14 After the user purchases the WiFi module 5 and the connector 51, the fixing part 3 is removed, and the connector 4 is inserted from one side of the guide rib 34 between the two first limiting ribs 321. It is fixed under the abutment of the first limiting part 311 and the second limiting part 312. The connecting wire 43 passes through the outlet hole 35a. The connector 51 of the WiFi module 5 is inserted into the interface 4a of the connector 4. Then, the connector at the end of the connecting wire 43 is inserted into the socket on the circuit board 2 to realize the network connection. Finally, the positioning part 38 of the fixing part 3 is inserted into the positioning groove 11a, and the fastener is inserted into the first positioning hole 33b and the second positioning hole 11b to lock the fixing part 3.

[0096] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
