Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and more specifically, to a connecting shaft and an air conditioner. Background Technology

[0002] With the continuous advancement of air conditioning equipment, the demand for improved performance, reliability, and assembly efficiency is also increasing. In particular, the design and installation methods of internal mechanical components in air conditioners, while ensuring stable operation, place higher demands on simplifying the assembly process and improving maintenance convenience. In existing designs, the fixing methods between the connecting shaft and the air conditioner frame structure are often quite complex, which not only increases manufacturing costs but may also lead to longer assembly times and higher failure rates. Furthermore, due to the lack of an effective locking mechanism, loosening may occur after prolonged operation, affecting the overall performance of the air conditioner. Utility Model Content

[0003] The problems solved by this utility model are the complex fixing of the connecting shaft, insufficient long-term stability and inconvenient installation in the prior art.

[0004] To address the aforementioned problems, this utility model provides a connecting shaft assembly for use in an air conditioner. The air conditioner includes a drive motor and a frame structure, comprising: a connecting shaft and a locking assembly. The connecting shaft is connected to the drive motor, providing rotational power to the connecting shaft. The locking assembly is mounted on the connecting shaft, and the connecting shaft is fixed to the frame structure via the locking assembly. The locking assembly includes a stabilizing connector, which has a middle portion and an edge portion, with the edge portion being longer than the middle portion. The connecting shaft is sequentially fixed to the frame structure according to the length of the locking assembly.

[0005] The technical effects achieved by adopting this solution are as follows: By optimizing the length of the components, the connecting shaft can be securely fixed to the air conditioner's frame structure. This design not only enhances the overall mechanical strength of the component but also improves operational reliability and reduces vibration and noise. Because the locking components have specific lengths and are sequentially fixed to the frame structure according to their lengths, the installation process is more intuitive and convenient. Technicians can easily position and install the locking components based on their lengths without requiring additional alignment tools or steps. When maintenance or component replacement is needed, the locking component design allows for quick disassembly and reassembly, reducing maintenance time and costs.

[0006] Furthermore, the locking component includes a positioning connector, which is mounted on the side of the connecting shaft away from the drive motor.

[0007] The technical effect achieved by adopting this technical solution is that the positioning connector is installed on the side of the connecting shaft away from the drive motor, which ensures the precise position of the connecting shaft in the frame structure. This helps to avoid mechanical failure or performance degradation caused by positional deviation.

[0008] Furthermore, a stabilizing connector is positioned between the positioning connector and the drive motor.

[0009] The technical effects achieved by adopting this technical solution are as follows: Multiple stable connecting parts are distributed between the positioning connecting parts and the drive motor, providing multi-point support and greatly enhancing the overall mechanical strength and stability of the connecting shaft assembly; through multiple stable connecting parts, the torque force from the drive motor can be more evenly distributed to the entire connecting shaft, avoiding local stress concentration and reducing component wear and fatigue.

[0010] Furthermore, the positioning connector is longer than the stabilizing connector; the positioning connector is preferentially installed on the frame structure, and multiple stabilizing connectors are sequentially installed on the frame structure along the direction from the drive motor to the positioning connector.

[0011] The technical effects achieved by adopting this solution are as follows: Because the positioning connector is relatively long and installed first, it provides an accurate reference position for the entire assembly from the very beginning. This ensures that other components can be more accurately aligned during subsequent installation, reducing installation errors. Furthermore, with a clear installation sequence, assembly personnel can operate according to predetermined steps, reducing training costs and operational difficulty.

[0012] Furthermore, the edge portion is preferentially installed on the frame structure, and the middle portion is subsequently installed on the frame structure; wherein, the positioning connector is arranged along the connecting shaft away from the drive motor, the middle portion is arranged along the connecting shaft away from the drive motor, and the edge portion is arranged along the connecting shaft toward the drive motor.

[0013] The technical effects achieved by adopting this solution are as follows: the longer edge section is installed first, providing precise guidance for the subsequent middle section and other components, ensuring the accurate positioning of the entire connecting shaft assembly in the frame structure, reducing installation errors, and improving accuracy and consistency.

[0014] Furthermore, the edge portion includes a first key and a second key, with the first key being closer to the drive motor; the first key is longer than the second key, and the first key is installed first, followed by the second key.

[0015] The technical effects achieved by adopting this technical solution are as follows: the different lengths of the first and second keys allow the power from the drive motor to be distributed more evenly on the connecting shaft, avoiding local stress concentration, thereby improving power transmission efficiency and extending the service life of the components.

[0016] Furthermore, the connecting shaft assembly also includes a fixing component and an air guide plate, with the fixing component disposed on the air guide plate and the connecting shaft passing through the fixing component.

[0017] The technical benefits of adopting this solution are as follows: By directly mounting the fixed components on the air guide plate, integrated component design is achieved, simplifying the assembly process. Assembly personnel can complete the installation of multiple components with a single operation, improving production efficiency.

[0018] Furthermore, the locking component is located on the side of the fixing component away from the air guide plate.

[0019] The technical effects achieved by adopting this technical solution are as follows: the design of locking the components away from the air guide plate ensures that it will not obstruct or interfere with the airflow path, ensuring that the air guide plate can efficiently guide the airflow and improve the cooling or heating efficiency.

[0020] To solve the above problems, this utility model provides an air conditioner, including a connecting shaft assembly as described in any of the above technical features. The air conditioner includes a frame structure, the connecting shaft assembly is mounted on the frame structure, and the frame structure is provided with a drive motor.

[0021] The technical effects achieved by adopting this solution are as follows: By optimizing the design of the connecting shaft assembly, especially the application of locking components, sturdy connectors, and fixing components, the mechanical stability of the entire air conditioner is greatly enhanced. This helps reduce vibration and noise during operation and improves the reliability of the system.

[0022] Furthermore, the frame structure includes a fixing device that is fixedly engaged with a locking component.

[0023] The technical effects achieved by adopting this technical solution are as follows: the tight combination of the fixing device and the locking component forms a multiple locking mechanism, which ensures the stability of the connecting shaft throughout the entire operating cycle, reduces the risk of loosening and falling off, and improves the safety of long-term use.

[0024] In summary, the various technical solutions described above in this application can have one or more of the following advantages or beneficial effects: i) By optimizing the design of the connecting shaft assembly, locking assembly, and frame structure, the mechanical stability of the internal structure of the air conditioner is significantly increased, which not only reduces vibration and noise during operation but also improves the reliability and service life of the system. ii) The compact and modular component design makes full use of limited space, helps to reduce the overall size of the air conditioner, facilitates lightweight product design, and also improves the neatness and aesthetics of the internal layout. iii) Clear installation direction and sequence, as well as the tight cooperation between the fixing device and the locking assembly, make the assembly process more intuitive and easier to operate, reduce the skill requirements of assembly personnel, and improve production efficiency and standardization.

Detailed Implementation

[0032] The purpose of this utility model is to provide a connecting shaft and an air conditioner, which can achieve the effects of simple fixing of the connecting shaft, easy installation and disassembly, and long-term use.

[0033] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0034] See Figure 1 , Figure 2 and Figure 3 This utility model provides a connecting shaft assembly 1 for an air conditioner 2. The air conditioner 2 includes a drive motor 21 and a frame structure 22. The air conditioner 2 includes a connecting shaft 11 and a locking assembly 12. The connecting shaft 11 is connected to the drive motor 21 and provides rotational power to the connecting shaft 11. The locking assembly 12 is installed on the connecting shaft 11 and the connecting shaft 11 is fixed to the frame structure 22 by the locking assembly 12. The locking assembly 12 includes a stabilizing connector 122, which has a middle part 123 and an edge part 124, with the edge part 124 being longer than the middle part 123. The connecting shaft 11 is fixed to the frame structure 22 sequentially according to the length of the locking assembly 12.

[0035] In this embodiment, by optimizing the length of the components, the connecting shaft 11 can be securely fixed to the frame structure 22 of the air conditioner 2. This design not only enhances the mechanical strength of the entire component but also improves operational reliability and reduces vibration and noise. Because the locking component 12 has a specific length and is sequentially fixed to the frame structure 22 according to its length, the installation process is more intuitive and convenient. Technicians can easily position and install the locking component 12 according to its length without additional alignment tools or steps. When maintenance or replacement of parts is required, the design of the locking component 12 allows for quick disassembly and reassembly, reducing maintenance time and costs.

[0036] Specifically, the air conditioner 2 is provided with a frame structure 22 and a drive motor 21. The connecting shaft 11 is installed on the frame structure 22 and connected to the drive motor 21. The locking component 12 helps to fix the connecting shaft 11 on the air conditioner 2. The locking component 12 includes a stabilizing part, and the stabilizing connecting part has a middle part and an edge part. The length of the edge part is greater than that of the middle part. The connecting shaft 11 is sequentially fixed to the frame structure 22 by the length of the locking component 12.

[0037] See Figure 2 , Figure 3 and Figure 4 The locking component 12 includes a positioning connector 121, which is installed on the side of the connecting shaft 11 away from the drive motor 21.

[0038] In this embodiment, the positioning connector 121 is installed on the side of the connecting shaft 11 away from the drive motor 21, which ensures the precise position of the connecting shaft 11 in the frame structure 22. This helps to avoid mechanical failure or performance degradation caused by positional deviation.

[0039] Specifically, the locking assembly 12 includes a positioning connector 121, which is fixedly mounted on the frame structure 22 on the side away from the drive motor 21.

[0040] See Figure 1 and Figure 3 The stabilizing connector 122 is disposed between the positioning connector 121 and the drive motor 21.

[0041] In this embodiment, multiple stabilizing connectors 122 are distributed between the positioning connector 121 and the drive motor 21, providing multi-point support and greatly enhancing the overall mechanical strength and stability of the connecting shaft assembly 1. Through multiple stabilizing connectors 122, the torque force from the drive motor 21 can be more evenly distributed to the entire connecting shaft 11, avoiding local stress concentration and reducing wear and fatigue of components.

[0042] Specifically, the stabilizing connector 122 is disposed between the positioning connector 121 and the drive motor 21.

[0043] See Figure 1 and Figure 3 The positioning connector 121 is longer than the stabilizing connector 122; the positioning connector 121 is preferentially installed on the frame structure 22, and multiple stabilizing connectors 122 are sequentially installed on the frame structure 22 along the direction from the drive motor 21 toward the positioning connector 121.

[0044] In this embodiment, because the positioning connector 121 is relatively long and is installed first, it can provide an accurate reference position for the entire assembly from the very beginning. This ensures that other components can be more accurately aligned during subsequent installation, reducing installation errors; with a clear installation sequence, assemblers can operate according to predetermined steps, reducing training costs and operational difficulty.

[0045] Specifically, the locking components 12 are installed on the frame structure 22 in sequence according to their length. The positioning connector 121 is longer than the stabilizing connector 122 and is fixed to the frame structure 22 first to help fix the entire connecting shaft 11 to the air conditioner 2. The stabilizing connector 122 is then fixed on the frame structure 22 in sequence from the drive motor 21 toward the positioning connector 121.

[0046] See Figure 1 and Figure 3 The edge portion 124 is preferentially installed on the frame structure 22, and the middle portion 123 is subsequently installed on the frame structure 22; wherein, the positioning connector 121 is arranged along the connecting shaft 11 away from the drive motor 21, the middle portion is arranged along the connecting shaft 11 away from the drive motor 21, and the edge portion 124 is arranged along the connecting shaft toward the drive motor 21.

[0047] In this embodiment, the edge portion 124 is longer and is installed first, providing precise guidance for the subsequent middle portion 123 and other components. This ensures the accurate positioning of the entire connecting shaft assembly 1 in the frame structure 22, reduces installation errors, and improves accuracy and consistency.

[0048] Specifically, the sturdy connector 122 includes a middle part 123 located in the middle section of the connecting shaft 11 and an edge part 124 located near the drive motor 21. The edge part 124 is longer than the middle part 123 and is preferentially installed on the frame structure 22, with the middle part 123 installed afterward.

[0049] The positioning connector 121 is fixed to the middle part 123 to the left and the edge part 124 is fixed to the right.

[0050] See Figure 1 , Figure 3 and Figure 5 The edge portion 124 includes a first key 1241 and a second key 1242. The first key 1241 is close to the drive motor 21. The first key 1241 is longer than the second key 1242. The first key 1241 is installed first, and the second key 1242 is installed later.

[0051] In this embodiment, the different lengths of the first key 1241 and the second key 1242 enable the power from the drive motor 21 to be distributed more evenly on the connecting shaft 11, avoiding local stress concentration, thereby improving power transmission efficiency and extending the service life of the components.

[0052] Specifically, the edge portion 124 includes a first key 1241 and a second key 1242. The first key 1241 is longer than the second key 1242. The first key 1241 is preferably installed on the frame structure 22, on the side close to the drive motor 21.

[0053] Furthermore, the installation sequence within the connecting shaft 11 is as follows: first, install the positioning connector 121; then, install the first key 1241; next, install the second key 1242; and finally, install the middle part 123. The positioning connector 121 and the middle part 123 are installed in the same direction; the first key 1241 and the second key 1242 are installed in the same direction; and the positioning connector 121 and the first key 1241 are installed in opposite directions.

[0054] See Figure 1 and Figure 3 The connecting shaft assembly 1 also includes a fixing component 13 and an air guide plate 14. The fixing component 13 is disposed on the air guide plate 14, and the connecting shaft 11 passes through the fixing component 13.

[0055] In this embodiment, the fixing component 13 is directly mounted on the air guide plate 14, realizing the integrated design of the components and simplifying the assembly process. Assembly personnel only need to complete the installation of multiple components in one operation, improving production efficiency.

[0056] Specifically, the connecting shaft assembly 1 includes a fixing component 13 and an air guide plate 14. The fixing component 13 is fixed on the air guide plate 14, and the connecting shaft 11 passes through the fixing component 13. The connecting shaft 11 is fixedly installed at the end away from the air guide plate 14.

[0057] See Figure 1 and Figure 3 The locking component 12 is located on the side of the fixing component 13 away from the air guide plate 14.

[0058] In this embodiment, the design of locking component 12 being far away from air guide plate 14 ensures that it will not obstruct or interfere with the airflow path, thus ensuring that air guide plate 14 can efficiently guide airflow and improve cooling or heating efficiency.

[0059] Specifically, the locking component 12 is disposed on the fixing component 13.

[0060] Furthermore, the positioning connector 121 is fixed on the side of the fixing assembly 13 away from the drive motor 21, the middle part 123 is fixed on the side of the fixing assembly 13 away from the drive motor 21, the second key 1242 is fixed on the side of the fixing assembly 13 close to the drive motor 21, and the first key 1241 is fixed on the side of the fixing assembly 13 close to the drive motor 21.

The air conditioner 2 includes a frame structure 22, the connecting shaft assembly 1 is mounted on the frame structure 22, and the frame structure 22 is provided with a drive motor 21.

[0062] In this embodiment, by optimizing the design of the connecting shaft assembly 1, particularly through the application of the locking assembly 12, the stabilizing connector 122, and the fixing assembly 13, the mechanical stability of the entire air conditioner 2 is greatly enhanced. This helps reduce vibration and noise during operation and improves the reliability of the system.

[0063] Specifically, the air conditioner 2 includes a frame structure 22, a drive motor 21 fixed on the frame structure 22, and a connecting shaft assembly 1 fixed on the frame structure 22.

[0064] See Figure 1 and Figure 2 The frame structure 22 includes a fixing device 221, which is fixedly engaged with the locking component 12.

[0065] In this embodiment, the tight combination of the fixing device 221 and the locking component 12 forms a multiple locking mechanism, which ensures the stability of the connecting shaft 11 throughout the entire operating cycle, reduces the risk of loosening and falling off, and improves the safety of long-term use.

[0066] Specifically, the connecting shaft assembly 1 is installed on the frame structure 22 through the cooperation of the locking assembly 12 and the fixing device 221.
