Description

Technical Field

[0001] This application relates to the field of household appliance technology, and in particular to a positioning structure, motor structure, and clothes drying rack. Background Technology

[0002] Ceiling-mounted clothes drying racks typically have end caps at both ends of the motor to protect the internal moving and stators. During assembly, multiple sets of screws are usually used to secure one side of the end cap. However, in practice, the screws on one side of the end cap need to be tightened sequentially before tightening the screws on the other side. If the first screw is screwed in too deeply, it can press down one side of the end cap and cause the other side to lift, affecting subsequent assembly. Furthermore, tightening other screws can cause slight deformation of the end cap or create stress around the screw holes, impacting the overall structural stability and negatively affecting the lifespan of the end cap over prolonged use. Utility Model Content

[0003] This application provides a positioning structure, a motor structure, and a clothes drying rack to solve the problem in the prior art where uneven force on the end cover during the assembly process can cause deformation or stress, which in turn negatively affects the service life of the end cover.

[0004] In a first aspect, this application provides a positioning structure for a clothes drying rack, used for limiting and connecting the stator housing, gearbox body and end cover, including: a positioning male end and a positioning female end respectively disposed on adjacent stator housing, end cover or gearbox body, wherein the positioning male end is embedded in the positioning female end, thereby limiting and fixing the stator housing, end cover and gearbox body.

[0005] Furthermore, the positioning male end includes a protrusion disposed on the end cover or gearbox body, and the positioning female end includes a groove disposed on the edge of the stator housing, wherein the protrusion is movably embedded in the groove for connection and positioning.

[0006] Furthermore, the positioning male end includes a plurality of positioning cylinders disposed on the gearbox body, and the end cover is provided with positioning through holes corresponding to the positioning cylinders, through which the positioning cylinders pass.

[0007] Secondly, this application provides a motor structure for a clothes drying machine, which is applied to a clothes drying machine, including: a stator housing and a gearbox body disposed at both ends of the stator housing. One end of the stator housing is provided with an end cover, which is disposed between the stator housing and the gearbox body. The stator housing, the end cover and the gearbox body, which are in contact with each other, are connected and limited by a plurality of positioning structures as described above. The end cover and the gearbox body at the other end are respectively provided with connection positioning holes. A connecting rod is provided between the connection positioning holes of the end cover and the gearbox body. The two ends of the connecting rod pass through the connection positioning holes on the end cover and the gearbox body respectively, thereby limiting and fixing the end cover and the gearbox body.

[0008] Furthermore, the middle part of the end cap is recessed to one side to form a bearing placement groove.

[0009] Furthermore, the rotor inside the stator housing is connected to a worm shaft. The two ends of the worm shaft extend from the ends of the stator housing. The ends of the worm shaft pass through the end cover and the gearbox in sequence or directly through the gearbox, and mesh with the gear set inside the gearbox for transmission.

[0010] Furthermore, the end cover is a front end cover, the front end of the stator housing is connected and limited to the front end cover through a positioning structure, and the rear end of the stator housing is connected and limited to the gearbox body through a positioning structure.

[0011] Furthermore, the stator housing is symmetrically provided with connecting lugs on its edge, and the connecting lugs are provided with connecting holes. The gearbox body is provided with threaded holes corresponding to the connecting holes. By passing screws through the connecting holes and locking them in the threaded holes, the connection and fixation between the stator housing and the gearbox body can be achieved.

[0012] Furthermore, the stator housing has two connecting lugs at each end, and the two connecting lugs are symmetrically arranged on both sides of the end of the stator housing.

[0013] Thirdly, this application provides a clothes drying rack, including the electric motor structure of the clothes drying rack as described above.

[0014] The technical solutions provided in this application have the following advantages compared with the prior art:

[0015] Using the structure and assembly method provided in this application, during the assembly process, the end cover and gearbox body are sequentially assembled onto the end of the stator housing by matching the positioning male end and the positioning female end. During the assembly process, since the positioning structure is used for limiting connection, there is no need to use screws for locking during the assembly process. Therefore, the end cover will not deform during the screw locking process, and stress will not be generated at the end cover, thus affecting the service life of the end cover and ensuring the stability of the overall structure.

To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples.

[0027] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0028] To address the technical problem in existing technologies that may lead to uneven stress on the end cap, resulting in deformation or stress and negatively impacting its service life, this application provides a ceiling-mounted motor structure for a clothes drying rack. This structure enables matching and limiting of the positioning male and female ends of the corresponding positioning structure. Therefore, during assembly, screws are not required for tightening, preventing deformation of the end cap during screw tightening and thus avoiding stress that could affect its service life and ensuring the stability of the overall structure.

[0029] Please see Figure 1 , Figure 2 , Figure 3 This application provides a positioning structure 4 for a clothes drying rack, used for limiting and connecting the stator housing 1, gearbox 2 and end cover 3, including: a positioning male end 41 and a positioning female end 42 respectively disposed on adjacent stator housing 1, end cover 3 or gearbox 2, wherein the positioning male end 41 is embedded in the positioning female end 42, thereby limiting and fixing the stator housing 1, end cover 3 and gearbox 2.

[0030] In this application, the positioning male end 41 and positioning female end 42 of the corresponding positioning structure 4 are matched and connected for limiting, thereby improving the overall efficiency of the assembly process. Specifically, during the assembly process, the positioning male end 41 on the end cover 3 is aligned with the corresponding positioning female end 42 on the stator housing 1, and the end cover 3 is pushed towards the stator housing 1, so that the positioning male end 41 on the end cover 3 is embedded in the positioning female end 42 of the stator housing 1, realizing the connection limiting between the end cover 3 and the stator housing 1. Then, the positioning male end 41 on the gearbox 2 is aligned with the positioning female end 42 of the end cover 3, and the gearbox 2 is pushed towards the stator housing 1, so that the positioning male end 41 on the gearbox 2 is embedded in the positioning female end 42 of the end cover 3, realizing the connection limiting between the gearbox 2 and the stator housing 1. After the stator housing 1, end cover 3 and gearbox 2 are connected and positioned sequentially, the stator housing 1 and gearbox 2 are locked and fixed with screws 5. Since the connection and positioning can be achieved through the positioning structure 4 during the assembly process, there is no need to lock and fix the end cover 3 with screws. Therefore, the end cover 3 will not deform due to excessive screw tightening, which would generate stress at the end cover 3 and affect its service life. This effectively ensures the stability of the overall structure.

[0031] In some embodiments, the positioning male end 41 includes a protrusion 411 disposed on the end cover 3 or the gearbox 2, and the positioning female end 42 includes a groove 421 disposed on the edge of the stator housing 1. The protrusion 411 is movably embedded in the groove 421 for connection and limiting. By providing matching protrusions 411 and grooves 421 on the edges of the end cover 3 and the stator housing 1 respectively, the assembly of the end cover 3 can be prevented from going wrong through the cooperation of the protrusions 411 and the grooves 421. When the protrusions 411 and the grooves 421 are not aligned, the end of the protrusions 411 will contact the edge of the stator housing 1, thereby lifting the end cover 3 at a certain angle, making it easier for the operator to detect assembly abnormalities and adjust the end cover 3 and the stator housing 1 to meet the positioning assembly requirements. Meanwhile, when the protrusion 411 is embedded in the groove 421, it will limit the rotation of the end cover 3, so as to avoid the end cover 3 from being misaligned during subsequent assembly and affecting the overall assembly effect.

[0032] In some embodiments, the positioning male end 41 includes a plurality of positioning cylinders 412 disposed on the gearbox body 2, and the end cover 3 is provided with positioning through holes 422 corresponding to the positioning cylinders 412, through which the positioning cylinders 412 pass. By providing positioning cylinders 412 on the gearbox body 2 and positioning through holes 422 at corresponding positions on the end cover 3, when assembling the gearbox body 2 with the stator housing 1 after the end cover 3 is assembled, the positioning cylinders 412 are embedded into the corresponding end cover 3, thereby achieving a foolproof function in the assembly process, and limiting multiple axial and rotary joints of the gearbox body 2, preventing the gearbox body 2 from shifting before locking and fixing the gearbox body 2 and the stator housing 1, thus affecting the overall assembly effect and assembly efficiency.

[0033] Please see Figure 1 , Figure 2 , Figure 3 This application provides a motor structure for a clothes drying rack, including: a stator housing 1 and a gearbox 2 disposed at both ends of the stator housing 1. An end cap 3 is provided at one end of the stator housing 1, and the end cap 3 is disposed between the stator housing 1 and the gearbox 2. The stator housing 1, end cap 3, and gearbox 2, which are in contact with each other, are connected and limited by a plurality of positioning structures 4. Each positioning structure 4 includes: a positioning male end 41 and a positioning female end 42 respectively disposed on adjacent stator housing 1, end cap 3, or gearbox 2. The positioning male end 41 is embedded in the positioning female end 42, thereby limiting and fixing the stator housing 1, end cap 3, and gearbox 2. By matching and connecting the positioning male end 41 and positioning female end 42 of the corresponding positioning structures 4, the overall efficiency of the assembly process is improved. Because the positioning structure 4 can be used for connection and limiting during the assembly process, the locking operation is reduced. Only after the stator housing 1, end cover 3 and gearbox 2 are matched, screws 5 are used for locking and fixing. This avoids the need to use screws to lock and fix the end cover 3 in the traditional assembly process. This avoids the situation where the end cover 3 is thin and the screws are tightened too deeply, causing deformation of the end cover 3 or stress at the end cover 3, which would affect the service life of the end cover 3. This effectively ensures the stability of the overall structure.

[0034] The end cover 3 is a front cover 31. The front end of the stator housing 1 is connected and limited to the front cover 31 by a positioning structure 4, and the rear end of the stator housing 1 is connected and limited to the gearbox 2 by the positioning structure 4. In some embodiments, the front cover 31 is used for limiting connection only at one end of the stator housing 1, and the gearbox 2 is directly used for limiting connection at the other end of the stator housing 1. This saves the installation process at the rear end of the stator housing 1 and further improves assembly efficiency. This arrangement can provide effective protection for the stator housing 1 through the front cover 31 and the gearbox 2, while facilitating the direct disassembly of the gearbox 2 at the end without the end cover 3 when it is necessary to repair the components inside the stator housing 1, thus improving the efficiency of disassembly, assembly and repair.

[0035] In some embodiments, a worm shaft 13 is connected to the rotor inside the stator housing 1. Both ends of the worm shaft 13 extend from the ends of the stator housing 1. The ends of the worm shaft 13 pass sequentially through the end cover 3 and the gearbox 2, or directly through the gearbox 2, and mesh with the gear set inside the gearbox 2. The magnetic field between the stator and rotor inside the stator housing 1 provides the driving force, causing the worm shaft 13 connected to the rotor to rotate. This transmits the kinetic energy of the worm shaft 13 to the gear set inside the gearbox 2 at both ends, thereby driving the gear set to rotate. This satisfies the need to control the raising and lowering of the clothesline, facilitates the storage of the clothesline, prevents it from affecting the overall appearance, and allows the clothesline to be moved to a suitable height to meet the needs of drying and collecting clothes.

[0036] In some embodiments, please refer to Figure 4The end cap 3 and the gearbox 2 at the other end are respectively provided with connection positioning holes 33. A connecting rod 34 is provided between the end cap 3 and the gearbox 2. The two ends of the connecting rod 34 pass through the connection positioning holes 34 on the end cap and the gearbox 2, respectively, thereby limiting and fixing the end cap 3 and the gearbox 2. The connection between the connecting rod 34 and the connection positioning holes 33 on the end cap 3 and the gearbox 2 at the other end provides a fixed support between the end cap 3 and the gearbox 2 at the other end. This ensures positioning during assembly and ensures the stability of the overall structure during the operation of the ceiling-mounted motor. In particular, the end cap 3 and the gearbox 2 at the other end, which are fixed by the connecting rod 34, provide reinforcement for the stator housing 1. Since clothes need to be dried on the clothes drying rod connected to the reduction gear sets on both sides of the motor during use, there may be a situation where the clothes drying rod is subjected to greater force on one side during the drying process. Under long-term operating conditions, uneven stress can easily cause bending deformation at one end of the stator housing 1. By installing a connecting rod 34 between the end cover 3 and the gearbox 2 at the other end, the connecting rod 34 provides reinforcement and support, preventing bending deformation at one end of the stator housing 1 due to uneven stress on the overall structure during long-term operation. This would prevent abnormalities in the rotor shaft transmission and effectively ensure the overall service life and stability of the motor.

[0037] In some embodiments, one set of connection positioning holes 33 on the end cap 3 or the gearbox 2 at the other end is a through hole, and the other set is a threaded hole. For example, the connection positioning holes 33 on the gearbox 2 are through holes, and the connection positioning holes 33 on the end cap 3 are threaded holes. A long screw with threads at the end is used to pass through the connection positioning holes 33 on the gearbox 2 and lock it in the threaded hole of the end cap 3, thereby realizing the connection and fixation between the end cap 3 and the gearbox 2 at the other end.

[0038] In some embodiments, please refer to Figure 3The end cover 3 has a recessed center that extends to one side to form a bearing placement groove 311. The stator and rotor of the motor are housed in the stator housing 1. The rotor shaft passes through the end cover 3 and gearbox 2 from both ends of the stator housing 1, extending into the gearbox 2 and connecting to the input end of the gear set. Therefore, the bearing placement groove 311 is located at the center of the end cover 3, and a bearing is placed in the bearing placement groove 311, allowing the shaft to pass through the inner hole of the bearing. This provides positioning support for the shaft, preventing it from shifting during movement. Simultaneously, the bearing provides a low-friction contact surface for the shaft, effectively reducing friction during rotation. This ensures that when the shaft transmits power to the gear sets in the gearboxes 2 at both ends, the kinetic energy generated by the stator and rotor can be more effectively transferred to the gear sets, reducing kinetic energy loss due to friction and improving the mechanical efficiency of kinetic energy transmission.

[0039] In some embodiments, please refer to Figure 3 The stator housing 1 has symmetrically arranged connecting lugs 11 on its edge, and each connecting lug 11 has a connecting hole 12. The gearbox 2 has a threaded hole 21 corresponding to the connecting hole 12. A screw 5 passes through the connecting hole 12 and is locked into the threaded hole 21, thereby achieving the connection and fixation between the stator housing 1 and the gearbox 2. After the end cover 3 and the gearbox 2 are sequentially connected and positioned, a screw 5 passes through the connecting hole 12 and is locked into the threaded hole 21, thereby connecting and fixing the stator housing 1 and the gearbox 2. In some embodiments, the stator housing 1 has two connecting lugs 11 at each end, and the two connecting lugs 11 are symmetrically arranged on both sides of the end of the stator housing 1. In existing technologies, four screws 5 are typically installed on the same side of the stator housing 1 to connect and fix the single-sided gearbox 2 to the stator housing 1. Therefore, structurally, a total of eight screws 5 are required on both sides of the stator housing 1 to connect it to the gearbox 2 at both ends. This process is cumbersome, requiring repeated screw tightening, and is time-consuming. The tightening method provided in this application effectively improves assembly efficiency. Furthermore, before tightening the screws 5, the positioning structure 4 can limit and fix the stator housing 1, end cover 3, and gearbox 2, thereby improving the stability of the overall structure during screw tightening.

[0040] This application provides a clothes drying rack, including the motor structure of the clothes drying rack as described above. By using a positioning structure 4 with a matching connection between the male positioning end 41 and the female positioning end 42 for positioning and limiting, the overall efficiency of the assembly process is improved. This achieves mutual limiting and fixing of the stator housing 1, end cover 3, and gearbox 2, ensuring that the end cover 3 and gearbox 2 will not be misaligned during subsequent locking and fixing processes. This guarantees the stability and reliability of the overall assembly process. Furthermore, during assembly, there is no need for screw locking, thus preventing deformation of the end cover 3 during screw tightening and avoiding stress at the end cover 3 that could affect its service life, ensuring the stability of the overall structure.

[0041] This application improves the overall efficiency of the assembly process by matching and limiting the positioning male end 41 and positioning female end 42 of the corresponding positioning structure 4. During assembly, the end cover 3 and gearbox body 2 are sequentially assembled onto the end of the stator housing 1 through the matching of the positioning male end 41 and positioning female end 42. During the assembly process, since the positioning structure 4 is used for limiting connection, there is no need to use screws for locking during assembly. Therefore, the end cover 3 will not deform during the screw tightening process, thus avoiding stress at the end cover 3 and affecting its service life, and ensuring the stability of the overall structure.
