Description

Technical Field

[0001] The present application relates to the technical field of tubular motors, and in particular, to a connecting seat structure for a tubular motor. Background Art

[0002] Tubular motors are mainly used to provide power drive for equipment such as electric curtains, electric rolling shutters, electric awnings, and electric projection screens.

[0003] In order to address the vibration and noise problems generated during the operation of tubular motors, various traditional methods are commonly used in the industry to improve their performance. For example, a heavy metal outer shell is installed outside the motor to isolate sound transmission; a spring suspension system is used to absorb part of the vibration energy; or special materials are selected to make components to reduce friction and generate noise. In addition, some design solutions add a layer of soft gasket between the motor and the mounting base to disperse pressure and buffer impact force. However, although these measures can alleviate the impact of vibration and noise to a certain extent, they often have problems such as high structural complexity and high manufacturing cost, and do not fundamentally solve the problem.

[0004] A tubular motor includes a motor and a speed reducer, and the motor and the speed reducer are connected by a connecting seat. The connecting seat is generally made by injection molding. A connecting hole is generally provided in the middle of the connecting seat for connecting the output end of the motor. In the process of injection molding of the existing connecting seat, due to uneven cooling during the injection cooling process, there is stress inside the injection material, resulting in the circular hole in the middle of the formed connecting seat becoming out-of-round, making the connecting seat unable to be tightly assembled with the motor. At the same time, there will be a certain amount of vibration during the operation of the motor. The out-of-round connecting hole will cause uneven force on the connecting seat when connecting the motor, affecting the service life, and at the same time generating noise. Summary of the Invention

[0005] In order to solve the problem in the prior art that in the process of injection molding of the existing connecting seat, due to uneven cooling during the injection cooling process, there is stress inside the injection material, resulting in the circular hole in the middle of the formed connecting seat becoming out-of-round, affecting the assembly and use effects, the present application provides a connecting seat structure for a tubular motor.

[0006] A tubular motor connecting seat structure provided by this application adopts the following technical solution: A tubular motor connecting seat structure includes a motor and a speed reducer. The motor is in transmission connection with the speed reducer, and a connecting seat is arranged at the connection part. A flange protrudes outward from the edge of the connecting seat. A middle partition is arranged in the middle of the connecting seat. A connecting hole for connecting the output end of the motor is opened at the center of the middle partition. A circular connecting hole flange protrudes outward from one side edge of the connecting hole facing the motor. At least two reinforcing ribs are evenly spaced along the circumferential direction outside the connecting hole flange. One end of the reinforcing rib is connected to the connecting hole flange, and the other end is connected to the flange. The reinforcing rib is arranged in an arc shape.

[0007] By adopting the above technical solution, the arc-shaped reinforcing rib can adjust the cooling rate of the area around the connecting hole by increasing the surface area, reducing the deformation caused by the local rapid shrinkage of the material. The arc design of the reinforcing rib can guide the shrinkage direction and disperse the anisotropic stress during cooling, avoiding deviation from the design size due to uneven shrinkage around the connecting hole. The edge of the circular connecting hole is a stress concentration area. The arc-shaped reinforcing rib reduces the stress peak through a gentle geometric transition, reducing the microcracks caused by shrinkage stress during the cooling process. The reinforcing rib provides additional support, enhancing the structural strength of the hole wall and preventing the collapse or tearing of the area around the hole due to material weakness during cooling shrinkage. During the injection molding stage, the arc-shaped reinforcing rib can serve as a flow guiding structure to guide the molten plastic to fill the area around the hole more evenly, reducing the density difference after cooling caused by uneven flow, thereby reducing the internal stress. The arc-shaped reinforcing rib not only targets the cooling process but also enhances the fatigue resistance and impact resistance of the connecting hole during final use, avoiding cracking around the hole caused by cyclic loads. The arc-shaped reinforcing rib has a certain deformation ability and can play a buffering role during the operation of the motor, achieving shock absorption and improving the service life of the motor and the connecting seat.

[0008] Optionally, the thickness of the connecting hole flange gradually decreases in the direction towards the motor, presenting a frustum shape.

[0009] By adopting the above technical solution, the connecting hole flange is in a frustum shape. On the one hand, during the injection molding process, the injection molding material can fill the cavity faster and the distribution of the injection molding material is more uniform, thus improving the injection molding quality. On the other hand, during use, the thickness of the connecting hole flange gradually decreases in the direction towards the motor, presenting a frustum shape, which can effectively reduce the stress concentration when the connecting hole flange contacts the output end of the motor, improve the connection stability, and at the same time facilitate the insertion and positioning of the output end of the motor, simplifying the assembly process.

[0010] Optionally, a positioning post protruding from the surface of the flange is arranged on one side of the connecting hole.

[0011] By adopting the above technical solution, a positioning post protruding from the surface of the flange is provided on one side of the connection hole, which can achieve precise positioning of the connection seat and the motor output end, improve the assembly efficiency, and avoid the problem of unsmooth transmission caused by position deviation.

[0012] Optionally, connection protrusions flush with the flange surface are provided on two symmetric sides of the flange of the connection hole, and bolt holes are formed in the middle of the connection protrusions.

[0013] By adopting the above technical solution, connection protrusions flush with the flange surface are provided on two symmetric sides of the flange of the connection hole, and bolt holes are formed in the middle of the connection protrusions, which can achieve stable fixation of the connection seat and the motor output end or other components, and improve the reliability of the structure. The design of the connection protrusions flush with the flange surface helps to reduce stress concentration, enhance the strength of the connection part, and simplify the assembly process at the same time. The setting of the bolt holes provides a convenient way for connection, ensuring firm connection and easy disassembly and maintenance.

[0014] Optionally, there are four reinforcing ribs, and the four reinforcing ribs are bent in the same direction.

[0015] By adopting the above technical solution, four reinforcing ribs bent in the same direction are provided between the flange of the connection hole and the flange of the connection seat, which can significantly improve the structural strength of the connection seat and effectively prevent the connection seat from deforming due to external impact or vibration. At the same time, the arc design of the reinforcing ribs makes the force more uniform, further improving the stability and reliability of the connection seat.

[0016] Optionally, inner protrusions are circumferentially provided on the inner wall of one side of the connection seat connected to the reducer, and a plurality of convex ribs are evenly spaced on the side surface of the inner protrusion.

[0017] By adopting the above technical solution, inner protrusions are provided on the inner wall of one side of the connection seat connected to the reducer, which can enhance the structural strength of the connection seat in this area and avoid deformation caused by uneven force.

[0018] Optionally, a hollow is provided between the inner protrusion and the inner wall of the connection seat.

[0019] By adopting the above technical solution, a hollow is provided between the inner protrusion and the inner wall of the connection seat, which can effectively reduce the overall weight of the connection seat while maintaining the structural strength. In addition, there is a displacement space at the hollow during operation, which can play a shock-absorbing role.

[0020] Optionally, a protruding portion protrudes outward from the outer surface of the connection seat.

[0021] By adopting the above technical solution, the convex portion provided on the outer surface of the connecting seat can increase the structural strength of the connecting seat, and at the same time provide additional space and support positions for the installation of subsequent additional functional components, improving the versatility and adaptability of the connecting seat; the setting of the convex portion will not affect the overall assembly and use of the connecting seat, and helps to optimize the spatial layout of the connecting seat.

[0022] Optionally, a side hole is provided in the middle of the convex portion.

[0023] By adopting the above technical solution, a side hole is provided in the middle of the convex portion on the outer surface of the connecting seat, which can facilitate the operation or fixation of the connecting seat by external tools or components through the side hole, improving the convenience of installation and maintenance of the connecting seat.

[0024] Optionally, a clamping block is provided on the outer surface of the connecting seat.

[0025] By adopting the above technical solution, the provision of a clamping block on the outer surface of the connecting seat can facilitate quick positioning and fixation with other components, improving the assembly efficiency and enhancing the stability of the connection at the same time.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. In the present application, arc-shaped reinforcing ribs are provided around the connecting hole. By increasing the surface area, the arc-shaped reinforcing ribs can adjust the cooling rate in the area around the connecting hole, reduce deformation caused by local rapid shrinkage of the material, and the arc design of the reinforcing ribs can guide the shrinkage direction and disperse the anisotropic stress during cooling, avoiding deviation from the design dimensions due to uneven shrinkage around the connecting hole. The edge of the circular connecting hole is a stress concentration area, and the arc-shaped reinforcing ribs reduce the stress peak through a gentle geometric transition, reducing microcracks caused by shrinkage stress during the cooling process. The reinforcing ribs provide additional support, enhancing the structural strength of the hole wall and preventing collapse or tearing of the area around the hole due to material weakness during cooling shrinkage. During the injection molding stage, the arc-shaped reinforcing ribs can act as a flow guiding structure to guide the molten plastic to fill the area around the hole more evenly, reducing the density difference after cooling caused by uneven flow, thereby reducing internal stress. The arc-shaped reinforcing ribs not only target the cooling process but also enhance the fatigue resistance and impact resistance of the connecting hole during final use, avoiding cracking around the hole due to cyclic loading. The arc-shaped reinforcing ribs have a certain deformation ability and can play a buffering role during the operation of the motor, achieving shock absorption and improving the service life of the motor and the connecting seat; 2. The frustum-shaped structure of the connecting hole flange not only improves the strength of the connecting hole area but also optimizes the force conduction path, avoiding deformation or damage caused by excessive local stress. At the same time, the frustum shape has a better flow guiding effect during the injection molding process, enabling the injection molding material to fill the cavity faster and improving the product yield.

[0034] The following further elaborates on the present application in conjunction with the attached Figures 1-4 drawings.

[0035] This embodiment discloses a tubular motor connecting seat structure.

[0036] Refer to Figure 1, a tubular motor connecting seat structure, comprising a motor 1 and a speed reducer 2. The speed reducer 2 is connected to the motor 1 through a connecting seat 3. One side of the connecting seat 3 is fixedly connected to the housing of the speed reducer 2, and the other side is connected to the output end of the motor 1.

[0037] Referring to Figure 2 , the connecting seat 2 is cylindrical and has an intermediate partition 32 disposed in the middle thereof. One side edge of the intermediate partition 32 facing the motor 1 protrudes outward to form a flange 31. A connecting hole 33 for connecting the protrusion of the output end of the motor 1 is provided at the center of the intermediate partition 32. One side edge of the connecting hole 33 facing the motor 1 protrudes outward to form an annular connecting hole flange 37. Four reinforcing ribs 34 are uniformly spaced along the circumferential direction of the connecting hole 33 on the surface of the side of the intermediate partition 32 connected to the motor 1. The four reinforcing ribs 34 are all arranged in an arc shape and have the same bending direction. Arc-shaped reinforcing ribs 34 are provided around the connecting hole 33. By increasing the surface area, the arc-shaped reinforcing ribs 34 can adjust the cooling rate of the area around the connecting hole 33, reduce the deformation caused by the local rapid shrinkage of the material, and the arc design of the reinforcing ribs 34 can guide the shrinkage direction and disperse the anisotropic stress during cooling, avoiding deviation from the design dimensions due to uneven shrinkage around the connecting hole 33. The edge of the circular connecting hole 33 is a stress concentration area. The arc-shaped reinforcing ribs 34 reduce the stress peak through a gentle geometric transition, reducing the microcracks caused by the shrinkage stress during the cooling process. The reinforcing ribs 34 provide additional support, enhancing the structural strength of the hole wall and preventing the area around the hole from collapsing or tearing due to material weakness during cooling shrinkage. During the injection molding stage, the arc-shaped reinforcing ribs 34 can serve as a flow guiding structure to guide the molten plastic to fill the area around the hole more evenly, reducing the density difference after cooling caused by uneven flow, thereby reducing the internal stress. The arc-shaped reinforcing ribs 34 not only target the cooling process but also enhance the fatigue resistance and impact resistance of the connecting hole 33 during the final use, avoiding cracking around the hole due to cyclic loads. The arc-shaped reinforcing ribs 34 have a certain deformation ability and can play a buffering role during the operation of the motor, achieving shock absorption and improving the service life of the motor 1 and the connecting seat 3; Referring to Figure 4, the thickness of the connecting hole flange 37 gradually decreases in the direction towards the motor, presenting a frustum shape. The frustum-shaped structure of the connecting hole flange 37 not only improves the strength of the connecting hole 33 area but also optimizes the force conduction path, avoiding deformation or damage caused by excessive local stress. At the same time, during the injection molding process, the frustum shape has a better guiding effect, enabling the injection molding material to fill the cavity faster and improving the product qualification rate. A positioning post 36 protruding from the surface of the flange 31 is provided on one side of the connecting hole 33, which can achieve precise positioning of the connecting seat 3 and the output end of the motor 1, improving the assembly efficiency and avoiding problems such as poor transmission caused by position deviation. On both symmetric sides of the connecting hole flange 37, there are connecting protrusions 312 flush with the surface of the flange 31. A bolt hole 35 is provided in the middle of the connecting protrusion 312, which can achieve stable fixation of the connecting seat 3 and the output end of the motor 1 or other components, improving the reliability of the structure; the design of the connecting protrusion 312 being flush with the surface of the flange 31 helps reduce stress concentration, enhance the strength of the connecting part, and simplify the assembly process. The setting of the bolt 35 provides a convenient way for connection, ensuring firm connection and easy disassembly and maintenance.

[0038] Referring to Figure 3 , on the inner wall of the side where the connecting seat is connected to the reducer, there are inner protrusions arranged circumferentially. A number of convex ribs are evenly spaced on the side surface of the inner protrusions. There is a hollow between the inner protrusions and the inner wall of the connecting seat, which can effectively reduce the overall weight of the connecting seat while maintaining the structural strength. Additionally, during operation, there is a displacement space at the hollow part, which can play a shock-absorbing role. The outer surface of the connecting seat protrudes outward to form a protruding part, and a side hole is provided in the middle of the protruding part. The outer surface of the connecting seat is provided with a clamping block. During assembly, the connecting seat is positioned and assembled with the reducer housing through the protruding part and fixed to the reducer housing through the clamping block and the side hole, improving the assembly accuracy and convenience.

[0039] Therefore, this application effectively overcomes various shortcomings in the prior art and has high industrial utilization value.

[0040] The above embodiments are only illustrative of the principles and effects of this application and are not used to limit this application. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of this application. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed in this application should still be covered by the protection scope of this application.
