Description

TECHNICAL FIELD

Please refer to its full text, it is provided with motor body 1, casing 13, drive board 14, motor 15 and offline voice module 4 etc. The prior art curtain drive device is long strip as a whole, and the long strip design helps to increase the heat dissipation area of the motor. Heat will be generated during the operation of the motor, and if the heat dissipation is poor, it may lead to performance degradation or even damage of the motor. By increasing the axial length (the up-down direction of the curtain drive device after being installed on the guide rail), air convection can be more effectively utilized for heat dissipation, thereby prolonging the service life of the motor. Secondly, the design of the curtain motor often needs to consider its functional requirements. For example, some curtain motors need to integrate intelligent control modules, sensors and other components. The addition of these components may increase the volume of the motor. The long strip design can provide more installation space for these components, thereby meeting more complex functional requirements. However, longer curtain drive devices may be more susceptible to external forces in terms of structure, leading to vibration. This is because the relative displacement between different parts of a long object may be greater when subjected to external forces, thereby increasing the likelihood of vibration.

DETAILED DESCRIPTION

[0026] In order to facilitate the understanding of the present application, the following will be described in more detail with reference to the relevant drawings.

[0027] It should be noted that when an element is considered to be "connected" to another element, it can be directly connected to the other element and integrated as a whole, or a middle element can exist at the same time. The terms "mounting", "one end", "the other end" and similar expressions used herein are only for illustrative purposes.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this technology belongs. The terms used in the specification herein are only for the purpose of describing specific embodiments and are not intended to limit the present application. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0029] Please refer to Figures 1 to 7In one aspect, a window curtain speed reducer 100 is provided, which comprises a first planetary gear 102, a first inner gear sleeve 103, a second planetary gear 106 and a second inner gear sleeve 108, the first inner gear sleeve 103 is sleeved on the first planetary gear 102, the first inner gear sleeve 103 is provided with a helical tooth portion 104, the first planetary gear 102 is provided with a helical gear which is engaged with the helical tooth portion 104, the second inner gear sleeve 108 is sleeved on the second planetary gear 106, the second inner gear sleeve 108 is provided with a straight tooth portion 109, the second planetary gear 106 is provided with a straight gear which is engaged with the straight tooth portion 109, the first inner gear sleeve 103 and the second inner gear sleeve 108 are fixedly connected, and the output end of the first planetary gear 102 and the input end of the second planetary gear 106 are drivingly connected.

[0030] The first planetary gear 102 is engaged with the helical tooth portion 104 of the first inner gear sleeve 103, the contact area is increased by the helical tooth design, and the stability of transmission and the torque transmission capacity are improved. The second planetary gear 106 is engaged with the straight tooth portion 109 of the second inner gear sleeve 108, the manufacturing difficulty of the inner gear sleeve is simplified by the straight tooth design, and in combination with the helical gear, multi-stage speed reduction is realized, more stable and quieter window curtain transmission is realized, and the transmission efficiency is improved and the noise is reduced by the combination of the helical gear and the straight gear.

[0031] The helical gear is a gear with inclined teeth, which is at a certain angle with the transmission axis. The helical gear realizes more stable and stable transmission by the design of the inclined teeth, so that the contact area between the teeth is larger. This feature enables the helical gear to withstand greater torque and transmit more power, and produce less noise during transmission. The existing technology adopts a gear as a transmission component in the window curtain speed reducer, for example, the existing technology CN218468172U discloses a structure stable louver gear box. The existing technology generally has the following problems: the speed reducer adopts straight tooth gear transmission, which produces a large noise during work. The helical gear transmission of the speed reducer can well solve the problem of large noise during transmission, and the inner tooth ring matched with the helical gear should also be helical. However, once the helical inner tooth ring is long, the tooth angle or helix angle of the inner tooth ring is large, the forming difficulty is high; secondly, it is difficult to install multiple groups of helical gears in the inner tooth ring. The present application can well solve the problem of the existing window curtain speed reducer.

[0033] The first inner gear sleeve 103 and the second inner gear sleeve 108 are axially sleeved to form a mounting cavity, which simplifies the assembly process of the transmission system; the sleeve structure enables the output end of the first planetary gear 102 and the input end of the second planetary gear 106 to be directly connected for driving after being sleeved. The structure is simplified, the curtain reducer 100 is more compact and easy to install, and the overall stability and reliability of the transmission system are improved.

When the two are sleeved, the gear sleeve clamping piece 105 is clamped in the gear sleeve clamping part 110, the gear sleeve clamping part 110 is recessed along the axial direction, and the clamping opening of the recess is directed towards the gear sleeve clamping piece 105.

[0035] The design of the gear sleeve clamping piece 105 and the gear sleeve clamping part 110 fixes the sleeved parts by clamping, enhancing the stability of the structure; the recessed clamping opening is directed towards the gear sleeve clamping piece 105, making the clamping process smoother and more reliable.

[0036] Please refer to Figures 1 to 7 In another aspect, a curtain driving device 200 is provided, which includes a driving motor 201, a mounting housing 203, a power board 207, a control board 208, and the curtain reducer 100 described above. The driving motor 201, the curtain reducer 100, the power board 207, and the control board 208 are installed in the mounting housing 203, the output end of the driving motor 201 is drivingly connected with the input end of the curtain reducer 100, the driving motor 201, the power board 207, and the control board 208 are radially spaced apart along the driving motor 201, and the mounting housing 203 is provided with a plug-in part 212 near one end of the control board 208. The plug-in part 212 is used for plug-in mounting of a functional board 211 to the mounting housing 203, the control board 208 and the functional board 211 are both provided with an adapted connector 214, and the two are connected through the connector 214.

[0037] By integrating the components such as the driving motor 201, the curtain reducer 100, the power board 207, and the control board 208 in the mounting housing 203, the modular design of the system is realized; the intelligent and modular design of the curtain driving device 200 is realized, and the expandability and flexibility of the system are improved. The design of the plug-in part 212 enables the functional board 211 to be conveniently plug-in mounted to the mounting housing 203, improving the expandability of the system; at the same time, the installation and maintenance process is simplified, and the user experience is improved.

[0038] The above-mentioned functional board 211 can include one or a combination of the following in the prior art:

[0039] Communication module, responsible for communication between the function board 211 and the smart home system, remote control or other control devices. It may support multiple communication protocols such as Wi-Fi, Zigbee, RF433, etc.

[0044] Please refer to Figure 2 In the preferred embodiment, the control board 208 is arranged outside both the drive motor 201 and the power board 207, and the end of the control board 208 away from both is provided with the function board 211.

[0045] The control board 208 is arranged outside the drive motor 201 and the power board 207, avoiding electromagnetic interference and heat accumulation; the function board 211 is arranged at the end of the control board 208 away from both, further optimizing the layout and improving the space utilization. The function board 211 generally has signal transmitting and receiving functions, and the above arrangement ensures that the control board 208 and the function board 211 are closer to the outside of the inner cavity of the installation shell 203. If the function board 211 has a wireless transmitting and receiving function module, such an arrangement is more conducive to signal transmission and reception of the function board 211.

[0046] Please refer to Figure 2 In the preferred embodiment, the control board 208 is arranged outside both the drive motor 201 and the power board 207, and the end of the control board 208 away from both is provided with the function board 211.

[0047] The arrangement of the signal module allows the system to receive and send signals, achieving seamless linkage with the smart home platform or system. The preferred embodiment is to arrange the signal module on the function board 211.

[0048] Please refer to Figures 2 to 4In the preferred embodiment, the insertion part 212 is an insertion slot, which is arranged in the internal cavity of the mounting shell 203 and extends along the up-down direction of the mounting shell 203. The mounting shell 203 is provided with a plug opening 213 which communicates with the internal cavity and is located above the insertion slot. The functional plate 211 is inserted into the insertion slot through the plug opening 213, and the insertion slot is used to fix the functional plate 211.

[0049] The insertion slot is formed by two convex strips which are arranged at intervals. One side of the functional plate 211 is inserted into the concave cavity formed between the two convex strips. In this way, four convex strips are arranged to form two groups of concave cavities which can clamp the two sides of the functional plate 211. The utility model adopts the precise matching mechanism of the insertion slot and the plug opening 213. The insertion slot is ingeniously arranged in the internal cavity of the mounting shell 203 and extends along the up-down direction of the shell to ensure that the functional plate 211 can be inserted vertically and stably. At the same time, the top of the mounting shell 203 is specially designed with a plug opening 213 which directly communicates with the internal cavity and is precisely located above the insertion slot. The plug opening 213 provides an intuitive path and sufficient operation space for the insertion of the functional plate 211. When the functional plate 211 is slowly pushed into the plug opening 213, the edge of the functional plate 211 will closely fit the inner wall of the insertion slot until it is completely inserted and locked in the predetermined position. The design of the insertion slot not only ensures the stable installation of the functional plate 211, but also effectively prevents the functional plate 211 from shaking or accidentally falling off during use by its precise size and shape, thereby enhancing the stability and reliability of the entire window curtain driving device 200.

[0050] Please refer to Figures 2 to 4 In the preferred embodiment, the connectors 214 on the control plate 208 and the functional plate 211 are signal connected and / or electrically connected through flexible connecting plates (not shown in the figure). The flexible connecting plates can be installed into the mounting shell 203 from the plug opening 213, or can be plug-in installed into the mounting shell 203 from the plug opening 213.

[0051] The flexible connecting plate is longer than the installation housing 203, so that the functional plate 211 and the flexible connecting plate are pulled out together. The flexible connecting plate is designed to make the signal connection and electrical connection between the control plate 208 and the functional plate 211 more flexible and reliable. The flexible connecting plate can be installed in the installation housing 203 together with the functional plate 211 through the plug-in opening 213, which simplifies the installation process. When the functional plate 211 needs to be installed or replaced, the flexible connecting plate can be disassembled or reassembled with the connector 214 on the functional plate 211. After the required functional plate 211 is installed, the functional plate 211 and the flexible connecting plate are plugged into the installation housing 203, and the flexible connecting plate is folded in the installation housing 203. Of course, in some embodiments, the plug-in part 212 can be provided with electrode pins for plugging. Here, the electrode pins are electrically connected to the control plate 208, and the functional plate 211 is also provided with corresponding electrode pins, so that the functional plate 211 is plugged into the control plate 208 for electrical connection, which can replace the flexible connecting plate.

[0052] Please refer to Figure 4 In the preferred embodiment, the installation housing 203 is provided with openings at the upper and lower ends of the installation housing 203, which are in communication with the inner cavity of the installation housing 203. The openings are used to install the power supply plate 207 and the control plate 208 in the installation housing 203. The installation housing 203 is also provided with a housing top cover 204 and a housing bottom cover 205 that cover the openings. The housing top cover 204 is also provided with a pull-out opening. The housing top cover 204 is also provided with a decorative cover 206 that covers the upper surface of the housing top cover 204.

[0053] The openings make it easy to install the power supply plate 207 and the control plate 208 in the installation housing 203. The housing top cover 204 and the housing bottom cover 205 cover the openings and improve the efficiency of installing the control plate 208 and the functional plate 211. The housing top cover 204 and the housing bottom cover 205 also improve the stability of the structure and prevent dust from entering. The decorative cover 206 further beautifies the appearance and improves the user experience.

[0054] Please refer to Figure 8In further embodiments, the mounting shell 203 is further provided with a power cord 216, a lead slot 217 and a buckle 218. The output end of the power cord 216 is electrically connected to the input end of the power board 207. The input end of the power cord 216 is mounted on the buckle 218. The buckle 218 is clamped to the mounting shell 203. The power cord 216 is arranged in the lead slot 217. The output end of the power cord 216 is led out of the mounting shell 203 through the lead slot 217. The mounting shell 203 is correspondingly provided with a clamping groove (not shown) matched with the buckle 218 to achieve detachable connection and mounting. Of course, the power cord 216, the lead slot 217 and the buckle 218 can be arranged on the shell bottom cover 205 or both the shell bottom cover 205 and the mounting shell 203. The lead slot 217 and the buckle 218 are arranged to facilitate the arrangement of the power cord 216 on the mounting shell 203 and the electrical connection between the power cord 216 and the power board 207.

[0055] Please refer to Figure 2 , Figure 3 and Figure 5 In the preferred embodiments, the window curtain speed reducer 100 is further provided with a force relief rubber pad 210 at the output end thereof. The driving motor 201 is fixed to the window curtain guide rail through the force relief rubber pad 210. The driving motor 201 is sleeved with a mute cover 209. The driving motor 201 abuts against the inner cavity of the mounting shell 203 through the mute cover 209.

[0056] The arrangement of the mute cover 209 reduces the noise and vibration generated by the driving motor 201 during operation, thereby improving the comfort of the system.

[0057] The damping rubber pad 210 is ingeniously arranged at the connecting position between the output shaft of the driving motor 201 and the curtain driving mechanism. The damping rubber pad 210 can be made of a material with high elasticity, which can play a significant damping effect when the driving motor 201 works, greatly reducing the noise generated by the driving motor 201 due to vibration. Since the guide rail is fixed on the wall, it is more stable and has larger volume and mass. The driving motor 201 is fixed to the curtain guide rail through the damping rubber pad 210, and the main supporting force of the driving motor 201 is provided by the guide rail. The main force of the driving motor 201 also leaks to the guide rail when working, and only a small part of the force acts on the mounting shell 203. Therefore, the damping rubber pad 210 can absorb and slow down the vibration wave generated by the motor when working, thereby effectively reducing the generation and propagation of noise. At the same time, it can also isolate the direct rigid connection between the motor and the curtain driving mechanism to a certain extent, further reducing the noise and vibration caused by mechanical vibration, and providing a more quiet and comfortable use environment for the user. On the other hand, it can effectively absorb and disperse part of the force when the driving motor 201 outputs torque, thereby reducing the impact and pressure borne by the curtain driving mechanism. This damping effect not only helps to protect the parts of the curtain driving mechanism from damage, but also prolongs the service life of the entire device.
