Description

Technical Field

[0001] This utility model relates to the field of curtain motor technology, specifically a transmission component positioning assembly. Background Art

[0002] Many electric curtains have emerged on the market now. The curtains open and close automatically through a motor. When installing the motor, it needs to be placed coaxially with the rope roller. There are usually two rope rollers. The motor drives the coaxial rope rollers to rotate synchronously. The motor is usually installed at the end of the upper beam or in the middle of the upper beam. It is preferable to install the motor in the middle of the upper beam so that the two rope rollers are located on both sides of the motor, ensuring that the two rope rollers drive the curtain with balanced force.

[0003] Patent publication number CN118203231A discloses an electric drive mechanism for curtains, including a drive unit, a parallel transmission device, and a rope winding device. The parallel transmission device includes a reducer, an output component, a synchronous pulley, a transmission wheel, and a rotating shaft. The input shaft of the reducer is coaxially and horizontally fixedly connected to the output end of the drive unit. The output shaft of the reducer meshes coaxially with the inner wall of the output component. The outer wall of the output component is perpendicularly meshed with the transmission wheel via the synchronous pulley. The transmission wheel is a hollow gear, sleeved on the rotating shaft. Limiting rings are also provided on both sides of the transmission wheel. The rope winding device is sleeved on the rotating shaft and located on both sides of the transmission wheel. The synchronous pulley, transmission wheel, and output component are housed within a first housing.

[0004] The aforementioned patent also has the following problem: during the specific assembly process, since the transmission wheel is not positioned, the transmission shaft needs to be passed through the hollow hole on the transmission wheel in advance to restrict the position of the transmission wheel. Therefore, the aforementioned patent can only assemble the transmission shaft by first passing it through the hollow hole on the transmission wheel, which is quite limited. Utility Model Content

[0005] The technical problem this invention aims to solve is that the drive shaft can only be assembled by passing through the hollow hole on the drive wheel, which is a limitation.

[0006] The present invention solves the above-mentioned technical problems through the following technical solution: a transmission component positioning assembly, including a housing and a rotating shaft, a motor assembly is provided inside the housing, a sleeve is rotatably connected inside the housing, the rotating shaft passes through the sleeve and is drivenly connected to the sleeve, a transmission component is fixedly connected to the sleeve, and the motor assembly is drivenly connected to the transmission component.

[0007] The technical advantage of this solution is that by setting a sleeve, the sleeve is pre-installed inside the housing, and the transmission component is fixedly connected to the sleeve. The sleeve plays a positioning role for the transmission component. With the sleeve positioning the transmission component, the rotating shaft can be installed later. This solves the technical limitation of the prior art, which requires the transmission shaft to be passed through the hollow hole on the transmission wheel for assembly. Moreover, the installation of the rotating shaft later only requires the rotating shaft to pass through the sleeve and the opposite ends of the rotating shaft to protrude from the housing.

[0008] In a further optimization, the sleeves are rotatably connected to both opposite sides of the housing, and the transmission component is fixedly connected to one of the sleeves.

[0009] The technical advantage of this solution is that the two sleeves are rotatably connected to the opposite sides of the housing so that the central axes of the two sleeves coincide, ensuring that the rotating shaft can pass through the two sleeves at the same time, so that the rotating shaft and the sleeves maintain coaxiality.

[0010] Further optimization involves an integrally formed first limiting ring within the housing, which is rotatably connected to the corresponding sleeve.

[0011] The technical advantage of this solution is that a first limiting ring is integrally formed inside the housing. By rotating the sleeve to the corresponding first limiting ring, the sleeve can be stably rotated and connected inside the housing.

[0012] To further optimize the design, a first bearing is provided between the first limiting ring and the corresponding sleeve.

[0013] The technical advantage of this solution is that by setting the first bearing, the sleeve can be rotated and connected to the first limiting ring more smoothly and steadily.

[0014] In a further optimization, a support tube is also abutted between the two sleeves, and the rotating shaft passes through the support tube.

[0015] The technical advantage of this solution is that the support tube can position the two sleeves so that they maintain good coaxiality, allowing the subsequent rotating shaft to pass through the two sleeves more smoothly.

[0016] Further optimization involves providing multiple first arc-shaped plates within the housing to support the support tube.

[0017] The technical advantage of this solution is that the arc-shaped plate can support the support tube, ensuring that the support tube is stably installed inside the housing.

[0018] Further optimization involves two sets of motor assemblies arranged in parallel, and two transmission components arranged in parallel.

[0019] The technical advantage of this solution is that the arrangement of two motor components and two transmission components allows this application to be used for opening and closing two types of curtains, such as day and night curtains, thus having a wide range of applications.

[0020] Further optimization involves the motor assembly including a motor, the output end of which is connected to an output gear, the transmission component being a transmission gear, and the output gear engaging with the transmission component.

[0021] The technical advantage of this solution is that the transmission component is a transmission gear, which is driven by a motor to rotate the output gear. The output gear meshes with the transmission component to enable the transmission component to drive the sleeve to rotate.

[0022] Further optimization involves an integrally formed second limiting ring within the housing, which is rotatably connected to the output end of the motor.

[0023] The technical advantage of this solution is that a second limiting ring is integrally formed inside the housing. By rotating the output end of the motor to the second limiting ring, stable rotation of the motor output end can be achieved.

[0024] In a further optimization, the motor assembly also includes a power shaft rotatably connected within the housing, the output gear being fixedly connected to the power shaft, and the power shaft being rotatably connected to the second limiting ring.

[0025] The technical advantage of this solution is that, by providing a power shaft, the output gear can be easily fixed to the power shaft, so that the motor can drive the power shaft to rotate.

[0026] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of this utility model. Attached Figure Description

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0037] It should be noted that in the claims and specification of this patent, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one" does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes the element.

[0038] This utility model discloses a transmission component positioning assembly, such as Figure 1-8 As shown, it includes a housing 1 and a rotating shaft 2. A motor assembly is provided inside the housing 1. A sleeve 4 is rotatably connected inside the housing 1. The rotating shaft 2 passes through the sleeve 4 and is connected to the sleeve 4 in a transmission connection. A transmission component 9 is fixedly connected to the sleeve 4. The motor assembly is connected to the transmission component 9 in a transmission connection.

[0039] By setting the sleeve 4, the sleeve 4 is pre-installed into the housing 1, and the transmission component 9 is fixedly connected to the sleeve 4. The sleeve 4 plays a positioning role for the transmission component 9. Under the action of the sleeve 4, the transmission component 9 is positioned, which allows the rotating shaft 2 to be installed later. This solves the technical problem in the background technology that the transmission shaft can only be assembled by passing through the hollow hole on the transmission wheel first, which is relatively limited. Moreover, the installation of the rotating shaft 2 later only requires the rotating shaft 2 to pass through the sleeve 4 and the opposite ends of the rotating shaft 2 to protrude from the housing 1 to complete the installation. The assembly process is relatively simple and the installation is convenient.

[0040] Preferably, the transmission component 9 and the sleeve 4 can be integrally formed.

[0041] During operation, the motor assembly drives the transmission component 9 to rotate, which in turn drives the sleeve 4 to rotate. Since the rotating shaft 2 passes through the sleeve 4 and is connected for transmission, the transmission connection between the rotating shaft 2 and the sleeve 4 can be achieved by having a first through hole 17 on the sleeve 4. The cross-section of the first through hole 17 is preferably a polygonal hole, and the corresponding rotating shaft 2 is also a polygonal shaft, so that the polygonal hole and the polygonal shaft are compatible. Figure 5 , 6 As shown, this design enables the sleeve 4 to be connected to the drive shaft 2 and forms a quick assembly structure. The rotation of the sleeve 4 can drive the rotation shaft 2 to rotate.

[0042] The motor assembly can drive the sleeve 4 to rotate through gear transmission, belt transmission, or other means.

[0043] When gear transmission is used, the transmission component 9 is a transmission gear. An output gear can be set at the output end of the motor assembly. The sleeve 4 is driven to rotate through the meshing of the output gear and the transmission component.

[0044] When belt drive is used, the transmission component 9 is a pulley. A pulley can be set at the output end of the motor assembly. The outer rings of the two pulleys are connected to a belt, and the sleeve 4 is rotated through the transmission of the belt and the two pulleys.

[0045] like Figure 8 As shown, specifically, sleeves 4 are rotatably connected to both opposite sides of the housing 1, and the transmission component 9 is fixedly connected to one of the sleeves 4.

[0046] To facilitate the installation of the sleeve 4 into the housing 1, sleeves 4 are rotatably connected to opposite sides of the housing 1, i.e., there are two sleeves 4. The transmission component 9 is fixedly connected to one of the sleeves 4, such as... Figure 6 As shown, the transmission component 9 is fixed on the sleeve 4 on the left side. The central axes of the two sleeves 4 coincide to ensure that the rotating shaft 2 can pass through both sleeves 4 at the same time, thus ensuring the coaxiality of the transmission shaft 2 and the two sleeves 4.

[0047] like Figure 2 , 3As shown, specifically, a first limiting ring 10 is integrally formed inside the housing 1, and the first limiting ring 10 is rotatably connected to the corresponding sleeve 4.

[0048] When there is only one sleeve 4, a first limiting ring 10 is integrally formed inside the housing 1. The first limiting ring 10 is rotatably connected to one sleeve 4 to achieve the purpose of rotatably connecting the sleeve 4 inside the housing 1. In this case, the first limiting ring 10 is set on the left side wall of the housing 1. When there are two sleeves 4, two first limiting rings 10 are integrally formed inside the housing 1. The two first limiting rings 10 are set on the opposite left and right side walls of the housing 1 to achieve a stable rotatable connection of the sleeve 4 inside the housing 1. The integral forming of the first limiting ring 10 with the housing 1 is easier to manufacture.

[0049] like Figure 2 As shown, specifically, a first bearing 11 is also provided between the first limiting ring 10 and the corresponding sleeve 4.

[0050] By setting the first bearing 11, the sleeve 4 can be rotated and connected to the first limit ring 10 in a relatively stable and smooth manner, ensuring that the rotation of the sleeve 4 is stable and smooth.

[0051] like Figure 2 , 8 As shown, specifically, a support tube 6 is also abutted between the two sleeves 4, and the rotating shaft 2 passes through the support tube 6.

[0052] During assembly, after the two sleeves 4 are rotated and installed onto the housing 1, the support tube 6 is then installed between the two sleeves 4, with both ends of the support tube 6 abutting against one end of the two sleeves 4 respectively, to ensure that the support tube 6 will not move axially.

[0053] The function of the support tube 6 is to position the two sleeves 4 so that the two sleeves 4 maintain good coaxiality, so that the subsequent rotating shaft 2 can pass through the two sleeves 4 more smoothly.

[0054] When using the support tube 6, the support tube 6 includes a second through hole 5, the cross-section of the second through hole 5 is circular, and the rotating shaft 2 is a polygonal shaft. Preferably, the rotating shaft 2 is connected inside the support tube 6 to ensure that the rotating shaft 2 will not drive the support tube 6 to rotate.

[0055] like Figure 3 As shown, specifically, the housing 1 is also provided with a plurality of first arc-shaped plates 7 for supporting the support tube 6.

[0056] Multiple first arc-shaped plates 7 are integrally formed on the shell 1 and arranged along the central axis of the support tube 6 of the shell 1. The first arc-shaped plates 7 are provided with arc-shaped grooves that are adapted to the bottom of the support tube 6. The arc-shaped grooves cooperate with the support tube 6 to realize the supporting function of the first arc-shaped plates 7 on the support tube 6.

[0057] like Figure 2 As shown, specifically, there are two sets of motor assemblies arranged in parallel, and two transmission components 9 are arranged in parallel.

[0058] Preferably, two motor assemblies are used, with two corresponding transmission components 9 arranged in parallel, capable of driving two Venetian blinds or two honeycomb blinds, and driving the day and night honeycomb blinds to operate. The two motor assemblies are arranged side by side, capable of driving the day honeycomb blind and the night honeycomb blind respectively. This allows the present invention to be applicable not only to the opening and closing of Venetian blinds and honeycomb blinds, but also to day and night honeycomb blinds and day and night Venetian blinds.

[0059] like Figure 2 As shown, specifically, the motor assembly includes a motor 3, the output end of which is connected to an output gear 8, and the transmission component 9 is a transmission gear, with the output gear 8 meshing with the corresponding transmission component 9.

[0060] Motor 3 drives output gear 8 to rotate, and output gear 8 meshes with transmission component 9, thereby driving transmission component 9 to rotate. Transmission component 9 is fixedly connected to sleeve 4 to drive the sleeve 4 to rotate. Thus, motor 3 drives sleeve 4 to rotate through gear transmission.

[0061] The output gear 8 and the transmission component 9 can be directly meshed, or indirectly meshed by means of a transmission gear or other means.

[0062] Motor 3 includes a motor, which can be a low-power motor that directly outputs power and drives the sleeve 4 to rotate, or motor 3 includes a motor and a reducer, in which the reducer reduces the output of the motor and drives the sleeve 4 to rotate.

[0063] The housing 1 includes an upper cover and a lower cover 102, which are detachably connected. The sleeve 4 and the motor assembly in this application are both disposed inside the lower cover 102. The lower cover 102 is provided with a fixing post 15, which has holes for screws to insert. The motor assembly also includes a fixing sleeve 12 that covers the motor 3. The fixing sleeve 12 and the fixing post 15 are connected by screws so that the fixing sleeve 12 can be installed on the lower cover 102 and the motor 3 can be installed inside the housing 1. The bottom of the fixing sleeve 12 is provided with a second arc-shaped plate 16. Preferably, the second arc-shaped plate 16 is provided with an arc-shaped groove that adapts to the bottom of the support tube 6. The arc-shaped groove can adapt to the surface of the support tube 6 so that the fixing sleeve 12 and the motor 3 can be installed on the support tube 6 relatively stably.

[0064] Furthermore, since the support tube 6 includes a second through hole 5 with a circular cross-section, and the rotating shaft 2 is a polygonal shaft, preferably, the rotating shaft 2 is internally connected to the support tube 6 to ensure that the rotating shaft 2 does not drive the support tube 6 to rotate, thus the support tube 6 does not rotate. Therefore, no rolling friction occurs between the support tube 6 and the fixed sleeve 12, which can reduce the relative friction between the support tube 6 and the fixed sleeve 12 and improve the service life of the components.

[0065] like Figure 3 As shown, specifically, a second limiting ring 13 is integrally formed inside the housing 1, and the second limiting ring 13 is rotatably connected to the output end of the motor 3.

[0066] The housing 1 has an integrally formed second limiting ring 13. The output end of the motor 3 is rotatably connected to the second limiting ring 13 to achieve stable rotation of the motor output end.

[0067] The output end of motor 3 can be in two ways: one is shaft output, where the output end of motor 3 is an output shaft, and the output gear 8 is connected to the output shaft of motor 3 by a key connection to achieve stable rotation of the output end of motor 3.

[0068] The output end of the motor 3 forms a polygonal hole. The motor assembly also includes a power shaft 18 rotatably connected in the housing 1. The power shaft 18 is adapted to the polygonal hole. The output gear 8 is fixedly connected to the power shaft 18. The power shaft 18 is rotatably connected to the second limiting ring 13.

[0069] The output end of motor 3 can also adopt another hole output method. Specifically, the output end of motor 3 can be a polygonal hole, and the power shaft 18 can be a polygonal shaft. The polygonal shaft and the polygonal hole are compatible to form a quick-connect assembly structure. Moreover, the output gear 8 is fixedly connected to the power shaft 18, which facilitates the integral molding of the output gear 8 and the power shaft 18.

[0070] Specifically, a second bearing 14 is provided between the second limiting ring 13 and the output shaft of the power shaft 18 or the motor 3.

[0071] By setting the second bearing 14, the output shaft of the power shaft 18 or the motor 3 can be rotated and connected to the second limit ring 13 more smoothly, and the second bearing 14 can ensure that the output shaft of the power shaft 18 or the motor 3 is rotatably connected to the housing 1.

[0072] The preferred embodiment of this application uses two sleeves 4 and a support tube 6 between the two sleeves 4. In the installation process, the two sleeves 4 are first rotated and installed in the first limiting ring 10, and then the support tube 6 is installed so that the two ends of the support tube 6 abut against one end of the two sleeves 4 respectively. Finally, the motor assembly is installed. In this way, the rotating shaft 2 can be installed later. Compared with the prior art, which can only pre-install the transmission wheel and the rotating shaft 2, this application can pre-assemble the components in the housing 1, and finally only needs to install the rotating shaft 2 through the two sleeves 4 and the support tube 6. The installation process is more convenient.

[0073] Other embodiments of the present invention will readily occur to those skilled in the art upon consideration of the specification and practice of the disclosure herein. This application is intended to cover any variations, uses, or adaptations of the present invention that follow the general principles of the present invention and include common knowledge or customary techniques in the art not disclosed herein.
