Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and more specifically, to a bearing housing assembly and an air conditioner. Background Technology

[0002] Currently, in wall-mounted air conditioner indoor units, one end of the cross-flow fan blade is driven by a motor, while the other end is fixed by a bearing mounting bracket assembly.

[0003] In the current technology, the bearing mounting assembly in an air conditioner indoor unit generally consists of a bearing, a rubber assembly, and a bearing mounting base. The bearing is mounted on the bearing mounting base via the rubber assembly. During the assembly process, a staggered snap-fit ​​method is usually used to connect the bearing and the bearing mounting base. In addition, the rubber assembly is installed in the bearing mounting base entirely by its deformation. Although the installation method used in the current technology can achieve the purpose of installation, it is relatively laborious during the installation process and difficult to disassemble after installation, thus increasing the assembly difficulty and reducing the assembly efficiency. Summary of the Invention

[0004] This invention can solve the technical problems of difficult assembly and low efficiency of bearing mounting and disassembly between bearing housing and bearing.

[0005] To address the aforementioned problems, this invention provides a bearing housing assembly, comprising: a bearing housing with a bearing mounting space inside; and a bearing fixing part disposed within the bearing mounting space, the bearing fixing part including a connecting section and an extension section; wherein one end of the connecting section is connected to the inner wall of the bearing housing, the other end of the connecting section is connected to the extension section, and a gap exists between the extension section and the inner wall of the bearing housing.

[0006] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: by setting the connecting section and the extension section in the bearing fixing part, the bearing housing is fixed to the bearing; by setting a gap between the extension section and the inner wall of the bearing housing, the extension section can move towards the inner wall of the bearing housing after being squeezed, thereby increasing elasticity. The existence of elasticity will reduce the resistance of the bearing housing when installing the bearing, thereby ensuring the reliability of the assembly, reducing the assembly difficulty, and improving the assembly efficiency.

[0007] Furthermore, in one embodiment of the present invention, the extension segment includes a first extension segment and a second extension segment; wherein the first extension segment is disposed between the connecting segment and the second extension segment, and the second extension segment is suspended within the bearing mounting space.

[0008] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: the first extension segment is connected to the connecting segment, thereby improving the connection strength between the extension segment and the inner wall of the bearing housing, while the suspended setting of the second extension segment provides elasticity for the second extension segment, thereby improving the assembly efficiency of the bearing during installation.

[0009] Furthermore, in one embodiment of the present invention, multiple extension segments are provided, and there is a gap between two adjacent extension segments.

[0010] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: by setting multiple extension segments, the connection strength between the bearing housing and the bearing is further improved; furthermore, by setting a gap between two adjacent extension segments, when any extension segment is squeezed by the bearing sleeve, it can move individually towards the inner wall of the bearing housing, which further improves its elasticity and further reduces the difficulty of installation.

[0011] Furthermore, in one embodiment of the present invention, it further includes: a bearing sleeve having a first mounting position; at least one fastener disposed on the side of the extension away from the connecting section; wherein the fastener is engaged with the first mounting position.

[0012] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: by setting the first mounting position on the bearing sleeve, the connection between the bearing sleeve and the bearing housing can be realized, thereby achieving the fixation of the bearing.

[0013] Furthermore, in one embodiment of the present invention, the first mounting position is at least one groove formed in the bearing sleeve, and the fixing member is a protrusion provided in the extension section.

[0014] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: by setting the first mounting position and the fixing member as a groove and protrusion structure, the first mounting position and the fixing member can be snapped together, thereby improving the connection strength between the bearing sleeve and the bearing seat.

[0015] Furthermore, in one embodiment of the present invention, the bearing sleeve is further provided with a second mounting position, and the extension section is further provided with at least one limiting member that cooperates and connects with the second mounting position.

[0016] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: by setting the second mounting position and the limiting member, the bearing sleeve can be limited, which prevents the bearing sleeve from falling off the bearing seat when the bearing rotates, reduces damage to the bearing sleeve and the bearing, and improves the service life of the bearing seat assembly.

[0017] Furthermore, in one embodiment of the present invention, it further includes: a support rib disposed between the limiting member and the inner wall of the bearing seat.

[0018] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: the setting of the support rib improves the connection strength between the limiting member and the bearing seat, enhances the support strength of the limiting member for the bearing sleeve, and further prevents the bearing sleeve from falling off the bearing seat.

[0019] Furthermore, in one embodiment of the present invention, the second mounting position is a stepped surface structure provided at one end of the bearing sleeve.

[0020] Compared with the existing technology, the technical effects achieved by adopting this technical solution are as follows: the second mounting position is set as a stepped surface structure, which facilitates the locking and limiting of the bearing sleeve by the limiting component, reduces the locking difficulty, and improves efficiency.

[0021] Furthermore, in one embodiment of the present invention, it further includes: at least one limiting member disposed on the inner wall of the bearing housing, and the limiting member is engaged with the second mounting position of the bearing sleeve.

[0022] Compared with the existing technology, the technical effects achieved by adopting this technical solution are as follows: the limiting member is directly set on the inner wall of the bearing, which can also limit the bearing sleeve, and further improve the support strength of the limiting member, thereby improving the limiting efficiency.

[0023] Furthermore, the present invention also provides an air conditioner, the air conditioner comprising: a base having a bearing seat mounting position; and the bearing seat assembly described in the above embodiments, the bearing seat assembly being mounted on the bearing seat mounting position.

[0025] In summary, by adopting the technical solution of the present invention, the following technical effects can be achieved:

[0026] i) A gap is provided between the extension section and the inner wall of the bearing housing, so that the extension section can move towards the inner wall of the bearing housing after being squeezed, thereby increasing the elasticity of the extension section, further ensuring the reliability of the assembly between the bearing housing and the bearing, reducing the assembly difficulty and improving the assembly efficiency.

[0027] ii) By setting the second mounting position and the limiting member, the bearing sleeve is prevented from falling off the bearing housing, the damage to the bearing sleeve and the bearing is reduced, and the service life of the bearing housing assembly is improved;

[0028] iii) The provision of the support ribs improves the connection strength between the limiting member and the bearing seat, further preventing the bearing sleeve from falling off the bearing seat. Attached Figure Description

[0042] [First Embodiment]

[0043] See Figure 1 and Figure 2 The first embodiment of the present invention provides a bearing housing assembly 50, which includes, for example, a bearing housing 10 and a bearing fixing part 20; the bearing housing 10 has a bearing mounting space 12 inside, and the bearing fixing part 20 is disposed in the bearing mounting space 12; wherein, the bearing is installed in the bearing mounting space 12, and the bearing is fixed by the bearing fixing part 20.

[0044] It is understandable that the main purpose of the bearing housing 10 is to install the bearing. Therefore, a bearing mounting port (not shown in the figure) is provided at at least one end of the bearing housing 10. The bearing is inserted into the bearing mounting space 12 through the bearing mounting port, and finally the connection between the bearing and the bearing fixing part 20 is realized.

[0045] Preferably, the bearing fixing part 20 is provided with a connecting section 21 and an extension section 22; the connecting section 21 is connected to the inner wall 11 of the bearing housing, and the extension section 22 is an extension of the connecting section 21 toward the bearing mounting space 12, and there is a gap between the extension section 22 and the inner wall 11 of the bearing housing.

[0046] It is understandable that by providing an extension section 22 and a connecting section 21 in the bearing fixing part 20, on the one hand, the bearing housing assembly 50 can be fixed to the bearing through the cooperation between the connecting section 21 and the extension section 22; on the other hand, by providing a gap between the extension section 22 and the inner wall 11 of the bearing housing, the extension section 22 can move towards the inner wall 11 of the bearing housing after being compressed, thereby increasing the elasticity of the extension section 22, reducing the resistance during bearing installation, ensuring the reliability of assembly, reducing the difficulty of assembly, and improving the efficiency of assembly.

[0047] Preferably, the extension segment 22 can be configured in various forms, i.e., the heights of the ends of the extension segment 22 in the vertical direction can be the same or different; the extension segment 22 includes: a first extension segment 23 and a second extension segment 24; wherein, the first extension segment 23 connects the second extension segment 24 and the connecting segment 21, and the second extension segment 24 is suspended within the bearing mounting space 12; wherein, the first extension segment 23 is continuously and annularly arranged around the inner wall 11 of the bearing housing, and multiple second extension segments 24 are provided, and among the multiple second extension segments 24, a gap is provided between two adjacent second extension segments 24. The gap, that is, the second extension 24 is isolated from the adjacent second extension 24; it should be noted that since the first extension 23 is connected between the connecting section 21 and the second extension 24, the first extension 23 mainly plays a connecting role. Therefore, the first extension 23 can be regarded as a part of the extension 22, or it can be regarded as a part of the connecting section 21. That is, at this time, it can be considered that the bearing fixing part 20 is provided with the connecting section 21, the first extension 23 and the second extension 24, or the bearing fixing part 20 is only provided with the connecting section 21 and the second extension 24.

[0048] It is understandable that the first extension segment 23 is configured as a continuous annular structure, which can improve the connection strength between the extension segment 22 and the connecting segment 21. On the one hand, the second extension segment 24 is suspended in the bearing mounting space 12, and there is a gap between two adjacent second extension segments 24, which achieves the purpose of improving the elasticity of the extension segment 22. On the other hand, the gap between two adjacent second extension segments 24 allows any one of the second extension segments 24 to move individually toward the inner wall 11 of the bearing seat when it is compressed, thereby improving the elasticity of the second extension segment 24 and further improving the assembly efficiency between the bearing and the bearing fixing part 20.

[0049] Preferred, see Figure 3 and Figure 4The bearing fixing part 20 also includes a fixing member 241; the fixing member 241 is disposed at the end of the second extension 24 away from the first extension 23, and the fixing member 241 is used to fix the bearing; for example, the fixing member 241 can be a protrusion structure formed on the side of the second extension 24 facing the bearing mounting space 12.

[0050] Preferably, the bearing fixing part 20 further includes a limiting member 242; the limiting member 242 is disposed at the end of the second extension 24 away from the first extension 23, and the limiting member 242 is located above the fixing member 241; the limiting member 242 is mainly used to fix the end of the bearing, which can prevent the bearing from falling off the bearing seat 10 during rotation; for example, the limiting member 242 can also be configured as a protruding structure, that is, the limiting member 242 is a protrusion provided at the end of the second extension 24.

[0051] Further, see Figures 5-9 The bearing housing assembly 50 also includes a bearing sleeve 40 and a bearing 60; wherein, the bearing sleeve 40 is installed in the bearing mounting space 12, and a bearing mounting position (not shown in the figure) is provided inside the bearing sleeve 40, the bearing 60 is installed in the bearing mounting position, and a first mounting position 41 and a second mounting position 42 are provided outside the bearing sleeve 40, and the connection between the bearing sleeve 40 and the bearing fixing part 20 can be realized through the first mounting position 41 and the second mounting position 42.

[0052] Preferably, the connection between the bearing sleeve 40 and the bearing housing 10 can be achieved through the cooperation between the first mounting position 41 and the fixing member 241. For example, the first mounting position 41 can be at least one groove opened on the outside of the bearing sleeve 40. When the fixing member 241 is set as a protruding structure, the groove and the protruding structure cooperate and engage with each other, thereby realizing the connection between the bearing sleeve 40 and the bearing fixing part 20. In order to improve the connection efficiency between the first mounting position 41 and the fixing member 241 and improve the assembly efficiency, when setting the first mounting position 41, the groove structure can be set as an annular structure.

[0053] It is understood that the first mounting position 41 and the fixing member 241 can be connected by a protrusion and groove, or other methods can be used. For example, the fixing member 241 can be set as a buckle and the first mounting position 41 can be set as a slot. The connection between the fixing member 241 and the first mounting position 41 can also be achieved by the buckle and slot. Of course, the fixing member 241 and the first mounting position 41 can also be connected by other methods, as long as the connection between the bearing sleeve 40 and the bearing fixing part 20 can be achieved. It is not limited to the connection method described in the embodiment of the present invention.

[0054] Preferably, the second mounting position 42 cooperates with the limiting member 242 to limit the bearing sleeve 40. The second mounting position 42 is located at the end of the bearing sleeve 40 away from the bearing mounting opening, and the second mounting position 42 has a stepped surface structure. By cooperating with the limiting member 242, the bearing sleeve 40 can be prevented from falling out of the bearing mounting space 12 when the bearing 60 rotates.

[0055] Understandably, the second mounting position 42 and the limiting member 242 cooperate to fix and limit the bearing sleeve 40. The bearing sleeve 40 is limited by the cooperation between the protrusion and the stepped surface; of course, other methods can also be used for limiting. Figure 6 and Figure 7 As can be seen, after the bearing sleeve 40 is installed into the bearing mounting space 12, the end 43 of the bearing sleeve is exposed at the opening 13 provided in the bearing seat 10. Therefore, in order to limit the bearing sleeve 40, a cover plate can be provided in the opening 13. By providing the cover plate, the opening 13 can be closed, and the end 43 of the bearing sleeve can also be prevented from slipping out of the bearing mounting space 12.

[0056] Furthermore, the second mounting position 42 and the limiting member 242 can also limit the bearing sleeve 40 by means of a snap-fit ​​and slot. The snap-fit ​​can be set on the second extension section 24 and the bearing sleeve 40. The bearing seat 10 can limit the bearing sleeve 40 by means of a snap-fit ​​and slot. Of course, the second mounting position 42 and the limiting member 242 can also be connected by other means, as long as the limitation between the bearing seat 10 and the bearing sleeve 40 can be achieved, and it is not limited to the limitation method proposed in this embodiment.

[0057] [Second Embodiment]

[0058] The second embodiment of the present invention provides another bearing housing assembly 50. The bearing housing assembly 50 provided in this embodiment is an improvement on the bearing housing 10 in the above embodiment. It can be understood that the main purpose of the fixing member 241 is to fix the bearing housing 10 and the bearing sleeve 40 to prevent the bearing 60 from falling off during rotation, while the main purpose of the limiting member 242 is to limit the bearing sleeve 40. By setting the fixing member 241 on the second extension 24, the elasticity of the fixing member 241 is effectively improved, and the assembly efficiency between the bearing sleeve 40 and the bearing housing 10 is improved. Therefore, the fixing member 241 and the limiting member 242 can also be set in other ways.

[0059] For details, see Figure 10Alternatively, the fixing member 241 can be set on the second extension section 24, and the limiting member 242 can be set on the inner wall 11 of the bearing housing. In this way, the limiting member 242 can be set as a protrusion, and at least one limiting member 242 can be provided on the inner wall 11 of the bearing housing; or the limiting member 242 can be set as a ring structure, and the bearing sleeve 40 can also be limited by the ring structure; of course, the limiting member 242 can also be set in other ways, as long as it can limit the bearing sleeve 40, which will not be described in detail here.

[0060] [Third Embodiment]

[0061] The third embodiment of the present invention provides an air conditioner, wherein the air conditioner is provided with a base, and the base is provided with a bearing seat mounting position, the bearing seat mounting position being used to install the bearing seat assembly 50 in the above embodiment; the bearing seat assembly 50 is mainly used to fix the cross-flow fan blade shaft in the air conditioner.

[0062] Preferably, after the bearing housing assembly 50 of the above embodiments is installed, the air conditioner possesses all the technical features and all the beneficial effects of the bearing housing assembly 50 of the above embodiments, which will not be described in detail here.

[0063] While the present invention has been disclosed above, it is not limited thereto.
