[0036] An embodiment of the present application provides an air conditioner, including an air conditioner indoor unit according to any embodiment of the present application.

[0037] An air conditioner is a household appliance used to regulate indoor temperature, humidity, and air quality. It is mainly composed of several parts, including a compressor, condenser, evaporator, indoor unit, and outdoor unit.

[0038] The present application embodiment provides an air conditioner indoor unit 100, see Figures 1 to 4 The air conditioning indoor unit 100 includes a chassis 1 and a face frame 2. The chassis 1 has a first stopper 11 on at least one side along a first direction, which is perpendicular to the height of the air conditioning indoor unit 100 and the front-to-back direction of the air conditioning indoor unit 100. The face frame 2 is provided with a second stopper 21 corresponding to the first stopper 11, and the first stopper 11 and the second stopper 21 are engaged with each other in a limited manner.

[0039] For the convenience of describing the relative positional relationship of the internal structural components of the air-conditioning indoor unit 100, the first direction refers to the length direction of the air-conditioning indoor unit 100 after the air-conditioning indoor unit 100 is normally installed.

[0040] The indoor unit 100 is the part of the air conditioning system that processes indoor air. It is responsible for delivering processed air (e.g., cooling, heating, dehumidification, etc.) to the indoor environment. It typically includes components such as a fan, evaporator, and control panel, and is a key component in the air conditioning system's indoor air conditioning function.

[0041] The chassis 1 is an important component of the air conditioner indoor unit 100 and is usually located at the bottom of the air conditioner indoor unit 100. It plays a role in supporting and fixing other components. For example, it may be used to install key components such as the fan motor and evaporator, and provide stability for the structure of the entire indoor unit.

[0042] The front frame 2 is the visible exterior portion of the air conditioner indoor unit 100. Besides being aesthetically pleasing, it also has some functional features. For example, an air outlet may be located on the front frame 2, and components such as a display panel and operating buttons may also be integrated on the front frame 2.

[0043] First position-limiting member 11 is disposed on at least one side of chassis 1 along a first direction and is used to limit the position of face frame 2. The specific structure of first position-limiting member 11 is not limited herein and may, for example, take the form of a protrusion, a slot 212, a hook, or the like. First position-limiting member 11 is designed to cooperate with second position-limiting member 21 on face frame 2 in the first direction to accurately determine the position of face frame 2 relative to chassis 1 in that direction.

[0044] The second stopper 21 is provided on the face frame 2 and corresponds to the first stopper 11. Its structure must match that of the first stopper 11 to ensure proper positioning. The specific structure of the second stopper 21 is not limited here and is determined based on the specific structure of the first stopper 11. For example, if the first stopper 11 is a protrusion, the second stopper 21 is a slot 212 corresponding to the protrusion; conversely, if the first stopper 11 is a slot 212, the second stopper 21 is a protrusion corresponding to the slot 212.

[0045] The limiting cooperation form of the first limiting member 11 and the second limiting member 21 is not limited here.

[0046] Exemplarily, the first limiting member 11 is an elastic snap-fit ​​structure. When installing the face frame 2, the second limiting member 21 on the face frame 2 can squeeze the elastic part of the snap-fit ​​structure, and then the snap-fit ​​structure returns to its original shape to lock the second limiting member 21. This makes it convenient to disassemble and install, and facilitates the disassembly of the face frame 2 during after-sales maintenance or cleaning.

[0047] Exemplarily, the first limiting member 11 can be a limiting column with threads, and the corresponding second limiting member 21 is a structure with screw holes, which achieves a more secure limiting fit through threaded connection, and the position of the face frame 2 in the first direction can be fine-tuned by adjusting the depth of the thread.

[0048] For example, the second stopper 21 can be an adjustable structure. For example, the second stopper 21 is a slot 212 with a slider that can be moved within the slot 212 and fixed at different positions. This can accommodate first stoppers 11 of chassis 1 of different models or with different assembly tolerances, thereby improving versatility.

[0049] In some embodiments, the surface of the second limiting member 21 may be coated with a wear-resistant material to reduce wear caused by friction with the first limiting member 11 during long-term use, thereby extending the service life of the component.

[0050] The number of first limiting members 11 and second limiting members 21 is not limited herein; first limiting members 11 may be provided on two or more sides of the chassis 1 along the first direction, and corresponding second limiting members 21 may be provided on the face frame 2. This allows for more accurate and stable positioning of the face frame 2 in the first direction, preventing shaking or deviation of the face frame 2 in that direction.

[0051] The air conditioning indoor unit 100 provided in the embodiment of the present application has a first limiting member 11 on at least one side of the chassis 1 along the first direction, and the face frame 2 is provided with a second limiting member 21 corresponding to the first limiting member 11. The first limiting member 11 and the second limiting member 21 cooperate in a limiting manner, which is conducive to the positioning and installation of the chassis 1 and the face frame 2, improves the accuracy of assembly, reduces the debugging time during the assembly process, and improves production efficiency. The first limiting member 11 and the second limiting member 21 are arranged along the first direction, which can provide sufficient operating space for the disassembly and assembly of the chassis 1 and the face frame 2, facilitates personnel operation, and solves the problem of insufficient operating space on the top of the air conditioning indoor unit 100 for disassembly and assembly of the chassis 1 and the face frame 2 when it is installed on the ceiling. The limiting cooperation of the first limiting member 11 and the second limiting member 21 also helps to improve the convenience of disassembly and assembly of the face frame 2, reducing the difficulty and time cost of operation during maintenance.

[0052] In some embodiments, see Figures 1 to 4 The chassis 1 includes a main body 12 and a first limiting member 11. The first limiting member 11 is detachably provided on the main body 12. The main body 12 has a third limiting member 121. The first limiting member 11 and the third limiting member 121 are limitedly matched.

[0053] The main body 12 is the primary component of the chassis 1 and performs essential functions of the chassis 1, such as providing a mounting base for other components (such as the fan motor and evaporator) and providing basic support and stability for the entire bottom structure of the air conditioner indoor unit 100. The main body 12 typically has a specific shape and structure to accommodate the layout and installation requirements of the various components within the air conditioner indoor unit 100.

[0054] The third stopper 121 is provided on the main body 12 of the chassis 1 and is used to cooperate with the first stopper 11. The third stopper 121 is used to ensure the position accuracy of the first stopper 11 on the main body 12, thereby indirectly affecting the overall cooperation between the face frame 2 and the chassis 1.

[0055] The specific structure of the third limiting member 121 is not limited here. For example, it can be a protrusion, a groove, a slot 212 or other forms of structure, as long as it can achieve limiting cooperation with the first limiting member 11.

[0056] Here, the first limiting member 11 is detachably arranged on the main body 12, which means that the first limiting member 11 is not fixed to the main body 12 as an inseparable whole, but adopts a connection method that can be easily disassembled and installed. More specifically, it means that the first limiting member 11 and the third limiting member 121 are detachably connected.

[0057] The detachable connection allows the first limiter 11 to be removed from the main body 12 when, for example, repairing or replacing the first limiter 11 or performing special operations on the chassis 1 main body 12, and can be reinstalled on the main body 12 after the operation is completed while maintaining its original function and position relationship.

[0058] The specific structure of the detachable connection is not limited here, and it can be, for example, a snap connection, a screw connection, a plug connection, etc.

[0059] In some embodiments, the first limit member 11 and the third limit member 121 adopt a snap-fit ​​structure with a guide structure. When installing the first limit member 11, the guide structure can guide the first limit member 11 to accurately align with the third limit member 121, and then the snap-fit ​​is automatically tightened, which facilitates installation and improves installation accuracy.

[0060] In some embodiments, a positioning key and keyway structure are designed at the limiting cooperation between the first limiting member 11 and the third limiting member 121 to ensure that the first limiting member 11 can be accurately aligned in all directions when inserted into the main body 12, thereby improving the accuracy and stability of the connection.

[0061] In other embodiments, an elastic seal is provided at the limiting cooperation position between the first limiting member 11 and the third limiting member 121. When the first limiting member 11 is inserted into the main body 12, the seal can not only play a sealing role to prevent dust and other impurities from entering the connection part, but also provide a certain elastic force to enhance the stability of the connection.

[0062] The main body 12 is provided with a third stopper 121, which cooperates with the first stopper 11 to ensure accurate positioning of the first stopper 11 on the main body 12 of the chassis 1. The first stopper 11 is detachably connected to the third stopper 121, facilitating product manufacturing, maintenance, and repair.

[0063] In some embodiments, see Figures 1 to 4 The third limiting member 121 includes a first limiting hole 1211, and the second limiting member 21 includes a second limiting hole 211 corresponding to the first limiting hole 1211. The first limiting member 11 includes a limiting shaft 111, which is inserted into the first limiting hole 1211 and the second limiting hole 211 to limit the face frame 2 along the radial direction of the limiting shaft 111. The axial direction of the limiting shaft 111 is parallel to the first direction.

[0064] The first limiting hole 1211 is a hole structure provided on the third limiting member 121. Within the main body 12 of the chassis 1, the third limiting member 121 serves to position the first limiting member 11. The first limiting hole 1211 is a structure that enables the third limiting member 121 to position the first limiting member 11. The first limiting hole 1211 provides space for the limiting shaft 111 to pass through, limiting the limiting shaft 111 within the entire limiting structure.

[0065] Second limiting hole 211 is located on second limiting member 21 and corresponds to first limiting hole 1211. Second limiting member 21 is provided on face frame 2 and cooperates with first limiting member 11 on chassis 1 to determine the position of face frame 2 relative to chassis 1. The corresponding relationship between second limiting hole 211 and first limiting hole 1211 allows limiting shaft 111 to pass through both simultaneously, thereby establishing a position-limiting connection between chassis 1 and face frame 2 in a specific direction.

[0066] The limiting shaft 111 is a part of the first limiting member 11 and is a shaft-shaped structure. The function of the limiting shaft 111 is to pass through the first limiting hole 1211 and the second limiting hole 211 to limit the position of the face frame 2 in the radial direction of the limiting shaft 111.

[0067] The axial direction of the limiting shaft 111 is parallel to the first direction. It can be understood that the first limiting hole 1211 and the second limiting hole 211 formed by the limiting shaft 111 are both hole-shaped structures extending along the first direction. The limiting shaft 111 is provided with the first limiting hole 1211 and the second limiting hole 211 along the first direction to limit the position of the face frame 2.

[0068] The specific shapes of the first limiting hole 1211 and the second limiting hole 211 are not limited here.

[0069] For example, the first and second limiting holes 1211 and 211 are elliptical. These elliptical limiting holes have different dimensional limits in the major and minor axis directions. This allows the face frame 2 to have varying degrees of adjustability in different directions when the limiting shaft 111 passes through. For example, this allows for a certain amount of expansion and contraction in the major axis direction to accommodate varying assembly tolerances or thermal expansion and contraction during temperature changes, while still effectively limiting the face frame 2 in the minor axis direction.

[0070] For example, the first limiting hole 1211 and the second limiting hole 211 are waist-shaped holes. The two ends of the waist-shaped holes are semicircular, and the middle is a rectangular connecting portion. This shape of limiting hole can facilitate the insertion of the limiting shaft 111 during installation, while providing a certain amount of displacement space in a specific direction (such as the length of the rectangular portion), facilitating fine-tuning of component positions during assembly, and can also absorb some minor vibrations or displacements during operation.

[0071] The specific structure of the limiting shaft 111 is not limited here.

[0072] In some embodiments, the limiting shaft 111 has an elastic structure. For example, a layer of elastic rubber or plastic material is wrapped around the outer circumference of the limiting shaft 111. When the limiting shaft 111 is inserted into the limiting hole, the elastic material is squeezed and deformed. This, on the one hand, can provide a certain degree of cushioning, reducing the rigid impact between the limiting shaft 111 and the limiting hole when the air conditioner is operating, thereby reducing wear and noise. On the other hand, the elastic deformation can compensate for assembly tolerances to a certain extent, thereby improving the stability of the limiting effect.

[0073] The third limiting member 121 on the chassis 1, the second limiting member 21 on the face frame 2, and the limiting shaft 111 in the first limiting member 11 together form a limiting system. The first limiting hole 1211 in the third limiting member 121 and the second limiting hole 211 in the second limiting member 21 correspond to each other, and the limiting shaft 111 in the first limiting member 11 passes through these two limiting holes. Due to the presence of the limiting shaft 111, the movement of the face frame 2 can be restricted in the radial direction of the limiting shaft 111. The axial direction of the limiting shaft 111 is parallel to the first direction (i.e., the longitudinal direction of the air conditioner indoor unit 100 in this embodiment). In this way, the limiting shaft 111 can be installed on both sides of the air conditioner indoor unit 100, and sufficient installation space can be obtained when the air conditioner indoor unit 100 is installed against the ceiling. This limiting structure design helps to improve the installation accuracy of the face frame 2 of the air conditioner indoor unit 100 and reduce the installation difficulty.

[0074] In some embodiments, see Figures 1 to 4 The first limiting member 11 also includes a first limiting portion 112 and a second limiting portion 113. The first limiting portion 112 and the second limiting portion 113 are arranged at both ends of the limiting shaft 111 along the axial direction. The first limiting portion 112 passes through the first limiting hole 1211. The third limiting member 121 can limit the first limiting portion 112 along the axial direction of the limiting shaft 111, and the second limiting portion 113 can limit the face frame 2 along the axial direction of the limiting shaft 111.

[0075] The first limiting portion 112 is part of the first limiting member 11 and is located at one axial end of the limiting shaft 111. The first limiting portion 112 is connected to the limiting shaft 111 and can pass through the first limiting hole 1211. The first limiting portion 112 cooperates with the third limiting member 121 to limit the position of the first limiting member 11 relative to the third limiting member 121 in the axial direction of the limiting shaft 111, thereby providing an axial constraint for the limiting relationship between the entire face frame 2 and the chassis 1.

[0076] Second limiting portion 113, also part of first limiting member 11, is located at the other axial end of limiting shaft 111. Second limiting portion 113 is also connected to limiting shaft 111 and limits the position of face frame 2 in the axial direction of limiting shaft 111. Second limiting portion 113 prevents excessive displacement of face frame 2 in the axial direction of limiting shaft 111. Working together with first limiting portion 112 and other related limiting structures, second limiting portion 113 effectively limits the position of face frame 2 relative to chassis 1 in all directions.

[0077] The specific structures of the first limiting portion 112 and the second limiting portion 113 are not limited here.

[0078] Exemplarily, the first limiting portion 112 and the second limiting portion 113 are both limiting block structures. The block structure of the first limiting portion 112 abuts against the third limiting member 121 for limiting position, and the block structure of the second limiting portion 113 abuts against the face frame 2 for limiting position.

[0079] In some embodiments, an elastic buffer layer, such as a rubber pad or spring structure, is provided at the contact area between the second stopper 113 and the face frame 2. When the air conditioner generates vibrations during operation or when the face frame 2 is subjected to external forces, the elastic buffer layer can absorb some of the energy, reducing the rigid impact between the face frame 2 and the second stopper 113, thereby reducing noise and protecting the surface of the face frame 2 from scratches.

[0080] In some embodiments, the second stopper 113 can be detachable, for example, connected to the stopper shaft 111 via a snap-fit ​​structure or a magnetic structure. When deep maintenance or cleaning of the interior of the air conditioner is required, the second stopper 113 can be easily detached from the stopper shaft 111 for easier operation. After the operation is complete, it can be easily reattached to restore its stopper function.

[0081] By providing first limiting portion 112 and second limiting portion 113 on limiting shaft 111, third limiting member 121 can limit the first limiting portion 112 along the axial direction of limiting shaft 111, and the second limiting portion can limit the face frame 2 along the axial direction of limiting shaft 111. In this way, face frame 2 is positioned and restricted in the axial direction relative to chassis 1. The simple limiting structure facilitates easy assembly and disassembly of face frame 2.

[0082] In some embodiments, see Figures 1 to 4 The third limiting member 121 includes a main body 1212 and a blocking portion 1213. The main body 1212 and the blocking portion 1213 define a accommodating cavity 1214. The blocking portion 1213 is provided with a first limiting hole 1211 that penetrates the blocking portion 1213 along the first direction. The first limiting portion 112 is provided in the accommodating cavity 1214. The blocking portion 1213 limits the first limiting portion 112 along the axial direction of the limiting axis 111.

[0083] The main body 1212 is a component of the third position-limiting member 121 , and provides basic shape and structural support for the entire third position-limiting member 121 .

[0084] The shape and size of the main body 1212 are not limited here, and are determined based on the structural layout of the chassis 1 of the air-conditioning indoor unit 100 and the coordination requirements with other components (such as the first limiting member 11) so that it can function stably in the entire limiting structure system.

[0085] In some embodiments, reinforcing ribs are provided within or on the surface of the main body 1212. The ribs can have various shapes and layouts, such as a crisscross grid or strips arranged along a specific direction. These ribs can increase the structural strength of the main body 1212, making it less susceptible to deformation under vibrations and external forces during air conditioner operation. This helps maintain the shape and dimensional stability of the accommodating cavity 1214 formed with the blocking portion 1213, ensuring the effective positioning of the first limiting portion 112.

[0086] The blocking portion 1213 cooperates with the main body 1212 to define an accommodating cavity 1214 and is provided with a first limiting hole 1211 extending through the blocking portion 1213 along a first direction. One of the main functions of the blocking portion 1213 is to limit the first limiting portion 112 in the axial direction of the limiting shaft 111, preventing the first limiting portion 112 from excessive axial movement, thereby ensuring the stability and accuracy of the entire limiting structure in the axial direction.

[0087] In some embodiments, the blocking portion 1213 is designed to have an elastic structure. For example, the blocking portion 1213 is made of an elastic material (such as rubber, elastic plastic, etc.) or an elastic buffer layer is provided at the portion where the blocking portion 1213 contacts the first limiting portion 112. When the first limiting portion 112 is subjected to a certain impact force in the axial direction (such as when the air conditioner is vibrated during transportation), the elastic blocking portion 1213 can buffer this impact force, preventing damage to the component caused by rigid collision. At the same time, it can also automatically adjust the limiting force of the first limiting portion 112 to a certain extent, maintaining the stability of the limiting structure.

[0088] The accommodating cavity 1214, defined by the main body 1212 and the blocking portion 1213, is an area with a specific spatial shape and size. Accommodating cavity 1214 is used to accommodate the first limiting portion 112, providing a specific placement space for the first limiting portion 112 within the chassis 1 structure. The blocking portion 1213 restrains the first limiting portion 112, ensuring that the first limiting portion 112 is properly positioned within the accommodating cavity 1214, thereby affecting the entire limiting relationship between the face frame 2 and the chassis 1.

[0089] The specific structure of the accommodating cavity 1214 is not limited here. It is understood that the accommodating cavity 1214 is defined by the main body 1212 and the blocking portion 1213, and the structure of the accommodating cavity 1214 can be changed by controlling the structures of the main body 1212 and the blocking portion 1213.

[0090] In some embodiments, the size or shape of the accommodating cavity 1214 is adjustable. For example, by employing a slidable connection structure or a stretchable material between the main body 1212 and the blocking portion 1213, the volume or shape of the accommodating cavity 1214 can be adjusted based on the actual size or assembly requirements of the first stopper 112. This design can accommodate first stoppers 112 of varying sizes, improving the versatility of the entire stopper structure and reducing adaptation issues caused by component size differences.

[0091] In some embodiments, a sealing structure is provided at the opening or within the accommodating cavity 1214. For example, a sealing strip or a sealing gasket is provided in the gap between the accommodating cavity 1214 and the first position-limiting portion 112 to seal the accommodating cavity 1214. This prevents impurities such as dust and moisture from entering the accommodating cavity 1214, thereby preventing these impurities from corroding or affecting the first position-limiting portion 112 and the internal structure of the accommodating cavity 1214, thereby extending the service life of the components and improving the reliability of the air conditioner indoor unit 100.

[0092] The third limiting member 121 is composed of a main body 1212 and a blocking portion 1213, which together form a receiving cavity 1214. The blocking portion 1213 is provided with a first limiting hole 1211 extending along a first direction, and this limiting hole is associated with the first limiting portion 112 mentioned above. The first limiting portion 112 is located within the receiving cavity 1214. Due to the presence of the blocking portion 1213, the blocking portion 1213 can limit the movement of the first limiting portion 112 in the axial direction of the limiting shaft 111. This further clarifies the limiting relationship between the first limiting member 11 and the third limiting member 121 in the axial direction, which helps to improve the accuracy and stability of the axial positioning of the face frame 2 relative to the chassis 1.

[0093] In some embodiments, see Figures 1 to 4 A blocking body 12131 is provided on the side of the blocking portion 1213 facing the accommodating cavity 1214. When the first limiting portion 112 rotates to a preset position, the first limiting portion 112 abuts against the blocking body 12131 to prevent the first limiting member 11 from rotating with the third limiting member 121.

[0094] The blocking body 12131 is a structural component disposed on the side of the blocking portion 1213 facing the accommodating cavity 1214. The blocking body 12131 is configured to abut against the first position-limiting portion 112, thereby preventing rotation between the first position-limiting member 11 and the third position-limiting member 121. The shape, size, and position of the blocking body 12131 are determined based on the design requirements of the overall position-limiting structure to ensure that the first position-limiting member 112 can be effectively prevented from rotating in a specific, predetermined position.

[0095] In some embodiments, the blocking body 12131 can be designed to be angle-adjustable. For example, it can be connected to the blocking portion 1213 via a rotating shaft, with an angle locking device provided at the connection. To meet different assembly requirements, the angle of the blocking body 12131 can be adjusted as needed, thereby changing the preset position of the first limiting portion 112. This increases the flexibility of the structure and adapts to a wider range of working conditions.

[0096] In some embodiments, the blocking body 12131 is made of an elastic material (such as rubber or elastic plastic), or an elastic buffer layer is provided at the contact portion between the blocking body 12131 and the first stopper 112. When the first stopper 112 rotates to a predetermined position and abuts against the blocking body 12131, the elastic structure can buffer the impact force, reduce rigid collisions between components, and reduce wear and noise. Furthermore, the elastic structure can automatically adapt to slight positional deviations of the first stopper 112 during rotation to a certain extent.

[0097] The preset position is a specific state position of the first limiting portion 112 during the rotation process.

[0098] The specific location of the preset position is not limited herein and is predetermined based on the overall structural design of the air conditioner indoor unit 100, the assembly relationship between the various components, and functional requirements. When the first limit portion 112 rotates to this preset position, it abuts against the blocking body 12131, thereby achieving a rotation-stopping engagement.

[0099] In some embodiments, auxiliary positioning structures, such as positioning pins and positioning holes, are provided near the contact area between the first position-limiting portion 112 and the blocking portion 1213. When the first position-limiting portion 112 approaches the preset position, the positioning pins and positioning holes can automatically align and cooperate, guiding the first position-limiting portion 112 to accurately rotate to the preset position, thereby improving assembly accuracy and efficiency.

[0100] The anti-rotation fit herein refers to preventing relative rotation between the first position-limiting member 11 and the third position-limiting member 121 by the abutment between the first position-limiting portion 112 and the blocking body 12131. In this structure, when the first position-limiting portion 112 rotates to a predetermined position and abuts against the blocking body 12131, the first position-limiting member 11 cannot further rotate relative to the third position-limiting member 121. This fit ensures that the components maintain a relatively fixed positional relationship in the rotational direction.

[0101] By providing a blocking body 12131 on one side of the accommodating cavity 1214, when the first limiting portion 112 rotates to a preset position, the first limiting portion 112 abuts against the blocking body 12131, thereby preventing the first limiting member 11 from rotating with the third limiting member 121. This increases the restriction on the rotational direction, effectively constraining the first limiting member 11 relative to the third limiting member 121 in all possible directions of movement (including axial and rotational directions), thereby more comprehensively ensuring the positional stability of the face frame 2 relative to the chassis 1, as well as the stability of the internal structure of the entire air conditioner indoor unit 100.

[0102] In some embodiments, see Figures 1 to 4 The third limiting member 121 further includes an elastic member 1215 disposed in the accommodating cavity 1214 , and the first limiting member 11 can abut against the blocking portion 1213 under the elastic force of the elastic member 1215 .

[0103] Elastic member 1215 is a component of third position-limiting member 121 and is located within accommodating cavity 1214. It exhibits elastic deformation, deforming when subjected to an external force and returning to its original shape upon removal. In this structure, elastic member 1215 primarily provides the spring force that forces first position-limiting member 11 against blocking portion 1213, providing support and positioning.

[0104] In some embodiments, the elastic member 1215 has an adjustable elastic force. The elastic force can be adjusted by rotating or moving a component to change the internal structure of the elastic member 1215. This allows the force with which the first limiting member 11 abuts against the blocking portion 1213 to be adjusted as needed to meet different assembly requirements.

[0105] By adding an elastic member 1215 within the accommodating cavity 1214 of the third limiting member 121, the elastic member 1215 exerts an elastic force on the first limiting member 11, which causes the first limiting member 11 to abut against the blocking portion 1213. The elastic member 1215 ensures that the abutting relationship between the first limiting member 11 and the blocking portion 1213 is not solely dependent on the shape and assembly relationship of the components, but is also maintained by the elastic force of the elastic member 1215, thereby providing additional constraint and stability to the position of the first limiting member 11 within the accommodating cavity 1214.

[0106] In some embodiments, see Figures 1 to 4 The third limiting member 121 further includes a pushing portion 1216 disposed in the accommodating cavity 1214 , and the pushing portion 1216 is sandwiched between the elastic member 1215 and the first limiting member 11 .

[0107] The push portion 1216 is a component of the third position-limiting member 121 and is located within the accommodating cavity 1214. The push portion 1216 is located between the elastic member 1215 and the first position-limiting member 11. Its primary function is to transmit force between the elastic member 1215 and the first position-limiting member 11. Furthermore, the push portion 1216 can adjust the direction and mode of force transmission.

[0108] Exemplarily, the elastic member 1215 is a spring structure disposed within the accommodating cavity 1214, and the pushing portion 1216 is a sheet-like structure interposed between the first stopper 11 and the spring. The pushing portion 1216 can slide relative to the accommodating cavity 1214 in a first direction, pushing the first stopper 11 in the first direction and transmitting the force of the elastic member 1215 to the first stopper 11 along the first direction. One side of the pushing portion 1216 contacts the first stopper 11, while the other side contacts the spring. This improves the contact condition between the elastic member 1215 and the first stopper 11, increasing the contact area.

[0109] In some embodiments, a guiding structure, such as a raised guide rail or a groove, is provided on the surface of the pushing portion 1216. These guiding structures can cooperate with the corresponding structure on the first limiting member 11 to accurately guide the moving direction of the first limiting member 11 while transmitting the elastic force, thereby further improving the positioning accuracy of the first limiting member 11 in the accommodating cavity 1214.

[0110] The third position-limiting member 121 has a pusher portion 1216 added to its structure. This pusher portion 1216 is located between the elastic member 1215 and the first position-limiting member 11, serving as an intermediate connection and force transmission mechanism. The elastic force generated by the elastic member 1215 acts on the first position-limiting member 11 through the pusher portion 1216, thereby pushing the first position-limiting member 11 against the blocking portion 1213. This structure makes force transmission more indirect and controllable. Compared to direct action of the elastic member 1215 on the first position-limiting member 11, it can better adjust the manner and force with which the first position-limiting member 11 abuts the blocking portion 1213.

[0111] In some embodiments, see Figures 1 to 4 The first limiting hole 1211 includes a first sub-hole 12111 and a second sub-hole 12112. A portion of the wall of the first sub-hole 12111 is radially recessed outward to form the second sub-hole 12112. The limiting shaft 111 passes through the first sub-hole 12111. The second sub-hole 12112 is used to prevent the first limiting member 11 from extending into the accommodating cavity 1214 along the first direction.

[0112] The first sub-hole 12111 is a portion of the first limiting hole 1211 and is used to pass through the limiting shaft 111. As the position where the limiting shaft 111 passes through, the first sub-hole 12111 provides the main accommodation and limiting space for the limiting shaft 111. Its shape and size are designed according to the specifications of the limiting shaft 111 and the requirements of the entire limiting structure to ensure that the limiting shaft 111 can pass through it and stably perform the radial limiting function.

[0113] The second sub-hole 12112 is formed by radially outwardly recessing a portion of the wall of the first sub-hole 12111. It primarily serves to avoid the first stopper 11, providing space for the first stopper 11 to extend into the accommodating cavity 1214 along the first direction. This prevents the first stopper 11 from interfering with the structure of the first stopper hole 1211 during movement, thereby ensuring the normal operation of the entire structure.

[0114] The specific shapes of the first sub-hole 12111 and the second sub-hole 12112 are not limited here.

[0115] For example, the first sub-hole 12111 is a circular hole, and the second sub-hole 12112 is a fan-shaped structure symmetrically arranged on both sides of the first sub-hole 12111. In this way, the first limiting portion 112 of the first limiting member 11 protrudes from the limiting shaft 111 and can extend from the second sub-hole 12112 into the accommodating cavity 1214. At the same time, the limiting shaft 111 is inserted into the first sub-hole 12111 and is constrained by the first sub-hole 12111.

[0116] Exemplarily, the opening portion of the second sub-hole 12112 is designed to be in a trumpet shape, so that when the first limiting member 11 extends into the accommodating cavity 1214, the first limiting member 11 can be guided in more conveniently, thereby reducing the possibility of collision.

[0117] The first limiting hole 1211 is composed of a first sub-hole 12111 and a second sub-hole 12112. The limiting shaft 111 is inserted into the first sub-hole 12111, ensuring the radial limiting function of the limiting shaft 111. The second sub-hole 12112 is provided for special avoidance requirements. When the first limiting member 11 needs to enter the accommodating cavity 1214 along the first direction, the second sub-hole 12112 can provide sufficient space to prevent the first limiting member 11 from colliding or obstructing the structure of the first limiting hole 1211. This design makes the interaction between the various components during movement and assembly more smooth and reasonable.

[0118] In some embodiments, see Figures 1 to 4The second limiting hole 211 includes a third sub-hole 2111 and a fourth sub-hole 2112. A portion of the wall of the third sub-hole 2111 is radially recessed outward to form the fourth sub-hole 2112. The limiting shaft 111 passes through the third sub-hole 2111. The fourth sub-hole 2112 is used to prevent the first limiting member 11 from extending into the accommodating cavity 1214 along the first direction.

[0119] The third sub-hole 2111 is a portion of the second limiting hole 211 and is used to pass through the limiting shaft 111. As the location for the limiting shaft 111 to pass through, the third sub-hole 2111 provides the main accommodation and limiting space for the limiting shaft 111. Its shape and size are designed according to the specifications of the limiting shaft 111 and the requirements of the entire limiting structure to ensure that the limiting shaft 111 can pass through it and stably perform its radial limiting function.

[0120] The fourth sub-hole 2112 is formed by radially outwardly recessing a portion of the wall of the third sub-hole 2111. It primarily serves to avoid the first stopper 11, providing space for the first stopper 11 to extend into the accommodating cavity 1214 along the first direction. This prevents interference between the first stopper 11 and the second stopper hole 211 during movement, thereby ensuring the normal operation of the entire structure.

[0121] The specific shapes of the third sub-hole 2111 and the fourth sub-hole 2112 are not limited here.

[0122] For example, the third sub-hole 2111 is a circular hole, and the fourth sub-hole 2112 is a fan-shaped structure symmetrically arranged on both sides of the third sub-hole 2111. In this way, the first limiting portion 112 of the first limiting member 11 protrudes from the limiting shaft 111 and can extend from the fourth sub-hole 2112 into the accommodating cavity 1214. At the same time, the limiting shaft 111 is inserted into the third sub-hole 2111 and is constrained by the third sub-hole 2111.

[0123] Exemplarily, the opening portion of the fourth sub-hole 2112 is designed to be in a trumpet shape, so that when the first limiting member 11 extends into the accommodating cavity 1214, the first limiting member 11 can be guided in more conveniently, thereby reducing the possibility of collision.

[0124] The second limiting hole 211 is composed of a third sub-hole 2111 and a fourth sub-hole 2112. The limiting shaft 111 is disposed in the third sub-hole 2111, ensuring the radial limiting function of the limiting shaft 111. The fourth sub-hole 2112 is provided for special avoidance requirements. When the first limiting member 11 needs to enter the accommodating cavity 1214 along the first direction, the fourth sub-hole 2112 provides sufficient space to prevent the first limiting member 11 from colliding or obstructing the structure of the second limiting hole 211. This design makes the interaction between the various components during movement and assembly more smooth and reasonable.

[0125] In some embodiments, see Figures 1 to 4 The second limiting portion 113 is provided on the surface of the face frame 2 away from the chassis 1 , and the second limiting portion 113 can limit the face frame 2 from moving away from the chassis 1 along the axial direction of the limiting axis 111 .

[0126] Second position-limiting portion 113 is positioned near the side of face frame 2 that is away from chassis 1. Thus, second position-limiting portion 113 can function as a position-limiting portion in the axial direction of position-limiting axis 111. Specifically, second position-limiting portion 113 limits the movement of face frame 2 away from chassis 1 along the axial direction of position-limiting axis 111, thereby helping to control the position of face frame 2 relative to chassis 1 and ensure the stability of the axial position of face frame 2 relative to chassis 1.

[0127] In some embodiments, see Figures 1 to 4 The second limiting portion 113 is provided with an anti-slip structure 1131 .

[0128] The anti-slip structure 1131 is a special structure provided on the second limiting portion 113 , and its purpose is to increase friction or provide a function of preventing sliding.

[0129] The specific form of the anti-slip structure 1131 is not limited here. For example, it can be a protrusion, texture, groove or special material coating provided on the second limiting portion 113.

[0130] In this way, when a person's hand rotates the second limiting portion 113 to drive the first limiting portion 112 to rotate to a preset position, the anti-slip performance between the second limiting portion 113 and the finger can be enhanced.

[0131] In some embodiments, see Figures 1 to 5 The first limiting member 11 is a buckle 114 provided on the chassis 1 , and the second limiting member 21 is a slot 212 provided on the face frame 2 corresponding to the buckle 114 .

[0132] The first limiting member 11 is a buckle 114 provided on the chassis 1 .

[0133] Buckle 114 is typically a mechanical component with elastic deformation capabilities. It can deform under certain external forces to connect with other components or to limit their position. In this scenario, buckle 114 acts as a limiting structural element on chassis 1, primarily for engaging with slot 212 on face frame 2 to limit the movement of face frame 2 relative to chassis 1.

[0134] The second limiting member 21 is a slot 212 structure located on the face frame 2 .

[0135] Slot 212 is a recessed structure whose shape and size are designed based on the buckle 114 (first stopper 11) it mates with. Slot 212 primarily accommodates buckle 114 and, through engagement with buckle 114, provides positioning and limiting in the assembly relationship between face frame 2 and chassis 1.

[0136] In some embodiments, the buckle 114 is integrally formed with the chassis 1 ; similarly, the slot 212 is integrally formed with the face frame 2 .

[0137] It should be noted that the first limiting member 11 may also be a slot 212 , and the second limiting member 21 may be a buckle 114 corresponding to the slot 212 .

[0138] By setting the first limiting member 11 as a buckle 114 provided on the chassis 1 and the second limiting member 21 as a corresponding slot 212 provided on the face frame 2, when assembling the face frame 2 and the chassis 1, the buckle 114 on the chassis 1 can be accurately inserted into the slot 212 on the face frame 2. Through the mutual cooperation between the buckle 114 and the slot 212, the movement of the face frame 2 relative to the chassis 1 in certain directions is restricted, ensuring that the relative position relationship between the face frame 2 and the chassis 1 meets the design requirements. This design has a simple structure, precise positioning and reliable installation.

[0139] It should be noted that, unless there is a conflict, the embodiments and technical features in the embodiments of this application can be combined with each other, and the detailed description in the specific implementation method should be understood as an explanation of the purpose of this application and should not be regarded as an improper restriction on this application.
