Description

Technical Field

[0001] This utility model relates to the field of electric curtain technology, and in particular to a concealed track curtain opening and closing control device. Background Technology

[0002] As people's living standards improve, motorized curtains are becoming increasingly popular. Currently, there are two types of concealed track curtain opening and closing control devices: a horizontal type installed along the same axis as the curtain track, and a vertical type installed perpendicular to the curtain track. The horizontal type is closer to the curtain track but occupies space, preventing a significant portion of the curtain from opening. The vertical type achieves the smallest possible wall-mounted space, allowing the curtain to open to its maximum extent; however, its internal planetary transmission structure results in an excessively long vertical length, which can affect the overall ambiance. Furthermore, the planetary transmission structure leads to more parts, more complex assembly, and higher costs.

[0003] Therefore, it is evident that the existing electric curtain opening and closing control devices still have inconveniences and defects in terms of structure, method, and use, and urgently need further improvement. How to create a new concealed track curtain opening and closing control device that is compact in structure, small in size, easy to assemble and disassemble, and highly responsive has become a pressing goal for the industry. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a concealed track curtain opening and closing control device, which is compact in structure, small in size, easy to disassemble and assemble, and highly sensitive in response, thereby overcoming the shortcomings of existing electric curtain opening and closing control devices.

[0005] To solve the above-mentioned technical problems, this utility model provides a concealed track curtain opening and closing control device, including a track terminal buckle assembly connected to a concealed track end connecting plate, and a curtain opening and closing control host disposed at the bottom of the track terminal buckle assembly. The curtain opening and closing control host includes, from top to bottom, a power connection shaft, a locking mechanism, a clutch mechanism, a drive mechanism, and an electronic control mechanism.

[0006] The locking mechanism is used to enable quick assembly and disassembly with the bottom of the track terminal fastening assembly;

[0007] The power connection shaft passes through the locking mechanism, and its upper end is used to insert into the connection hole of the track terminal fastening assembly and connect to the drive wheel of the concealed track. The lower end of the power connection shaft is used to connect to the clutch mechanism and is controlled by it to rotate.

[0008] The clutch mechanism includes an encoder disk, a clutch cam, a magnetic bead, a bearing cover, and a rigid bearing. The bottom of the encoder disk has a concave cavity, and the bearing cover closes the lower part of the concave cavity. The upper part of the clutch cam is configured as a cam structure with two opposing protrusions, and both the cam structure and the magnetic bead are located in the concave cavity of the encoder disk. The lower part of the clutch cam passes through the central hole of the bearing cover and connects to the drive mechanism. The inner wall of the concave cavity of the encoder disk has an arc-shaped groove that matches the magnetic bead, which allows the magnetic bead to engage when the clutch cam rotates under the drive mechanism, thereby enabling the clutch cam to drive the encoder disk to rotate, and the encoder disk to drive the power connection shaft to rotate. The rigid bearing is located at the lower part of the bearing cover, and the outer diameter of the rigid bearing is smaller than the inner diameter of the concave cavity of the encoder disk. It is used to attract the magnetic bead when the clutch cam is not rotating, causing it to detach from the arc-shaped groove, thereby separating the clutch cam from the encoder disk.

[0009] The drive mechanism drives the clutch cam to rotate under the control of the electronic control mechanism.

[0010] In a further improvement, four evenly distributed arc-shaped grooves are provided on the inner sidewall of the concave cavity of the encoder disk, and two magnetic beads are provided in the concave cavity of the encoder disk, respectively disposed on both sides of the cam structure.

[0011] In a further improvement, the drive mechanism includes a motor and a gear transmission mechanism. The gear transmission mechanism includes a worm, a double-layer gear, a first bevel gear, and a second bevel gear. The worm is fixed on the output shaft of the motor and rotates with the output shaft. One layer of the double-layer gear is a helical gear that meshes with the worm, and the other layer is a flat gear that meshes with the first bevel gear. The first bevel gear is a vertically arranged double-layer gear, and the second bevel gear is a horizontal bevel gear that meshes with the first bevel gear. The upper part of the second bevel gear is splinedly connected to the lower part of the clutch cam, and is used to rotate under the drive of the motor through the worm, the double-layer gear, and the first bevel gear, thereby driving the clutch cam to rotate.

[0012] In a further improvement, the gear transmission mechanism is mounted on a gear fixing plate. The gear fixing plate has a clearance hole through which the motor output shaft passes and a shaft bracket for fixing each gear. The upper end of the motor output shaft rotatably passes through the shaft bracket and is inserted into the center hole of the second bevel gear, serving as the center shaft of the second bevel gear.

[0013] In a further improvement, the encoder disk is also provided with an encoder disk cover plate, and an infrared encoder plate connected to the electronic control mechanism is provided between the encoder disk cover plate and the encoder disk.

[0014] In a further improvement, the locking mechanism includes a latch and a latch cover. The latch includes a ring and two L-shaped latches vertically arranged on the outer periphery of the ring, and an operating lever horizontally arranged on the outer periphery of the ring. The L-shaped latches are oriented in opposite directions. The latch cover has a central hole for the power connection shaft to pass through and an arc-shaped groove for the L-shaped latches to pass through. The operating lever extends out of the edge of the latch cover. The bottom of the track end engagement assembly has an arc-shaped groove for the L-shaped latches to extend into, and the L-shaped latches can engage with the track end engagement assembly under the rotation of the operating lever.

[0015] In a further improvement, the encoder cover plate has a central flange at its center for the power connection shaft to pass through, the ring is sleeved around the outer periphery of the central flange and rotates around the central flange as an axis, and the encoder cover plate is also provided with an elastic rocker plate to restrict the rotation of the control lever.

[0016] In a further improvement, the upper part of the latch cover is provided with at least one positioning pin, which corresponds to the positioning hole at the bottom of the track terminal fastening assembly;

[0017] Four connecting posts are provided at the four corners of the lower part of the outer cover of the latch. After the four connecting posts pass downward through the encoder cover plate, they are fixedly connected to the four corners of the bearing cover to realize the combined installation of the latch mechanism and the clutch mechanism.

[0018] In a further improvement, the electronic control mechanism includes a PCB main control board and a microphone, speaker, power interface, and network interface connected thereto.

[0019] Further improvements include a portable power supply that can be snapped onto the bottom of the curtain opening and closing control unit. The top of the portable power supply has a retractable power output port, which connects to the power interface at the bottom of the curtain opening and closing control unit when extended.

[0020] With this design, the present invention has at least the following advantages:

[0021] 1. This utility model's concealed track curtain opening and closing control device, through the setting of a clutch mechanism, enables free switching between automatic and manual opening and closing of the curtains, with high sensitivity in automatic opening and closing response. Furthermore, the worm gear structure and bevel gear configuration effectively reduce the size of the drive gearbox and the number of parts in the drive mechanism, facilitating disassembly and assembly. Moreover, the extended motor output shaft, serving as the central shaft of the second bevel gear, improves utilization. Combined with this bevel gear structure, the overall length of the curtain opening and closing control unit can be significantly shortened from the existing 300mm to 130mm, making it extremely compact, convenient to use, and improving environmental harmony.

[0022] 2. Furthermore, the L-shaped latch in the locking mechanism, in conjunction with the control lever, allows for easy assembly and disassembly of the main unit simply by pushing or pulling left or right, making it convenient and practical.

[0035] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0036] See attached document Figure 1 and 2 As shown, the concealed track curtain opening and closing control device of this embodiment includes a track end buckle assembly 2 connected to the concealed track end connecting plate 10, and a curtain opening and closing control host 1 disposed at the bottom of the track end buckle assembly 2. It should be noted that the concealed track described in this embodiment can adopt different tracks currently available on the market, such as... Figure 1 For 101 and 102, only different track end connecting plates need to be configured for them. The track end connecting plate 10 is set by those skilled in the art according to the actual track structure. Furthermore, the track terminal fastener assembly 2 of this application can be set at any end of the concealed track, such as the left or right end. Users can connect the curtain opening and closing control host 1 to the left or right side of the curtain as needed, which is convenient and flexible for adjustment according to the environment.

[0037] See attached document Figures 3 to 6 As shown, the curtain opening and closing control host 1 in this embodiment includes, from top to bottom, a power connection shaft 11, a locking mechanism 12, a clutch mechanism 13, a drive mechanism 14, and an electronic control mechanism 15.

[0038] The locking mechanism 12 is used to achieve quick assembly and disassembly with the bottom of the track terminal fastening assembly 2. Specifically, the locking mechanism 12 includes a latch 121 and a latch cover 122. The latch 121 includes a ring 1211 and two L-shaped latches 1212 vertically arranged on the outer periphery of the ring 1211, and a lever 1213 horizontally arranged on the outer periphery of the ring. The L-shaped latches 1212 are in opposite directions. The latch cover 122 has a central hole 1221 for the power connection shaft 11 to pass through and an arc-shaped groove 1222 for the L-shaped latches 1212 to pass through. The lever 1213 extends out of the edge of the latch cover 122, and its end has a handle 1214 for pulling the lever 1213 left and right. The bottom of the track terminal fastening assembly 2 is provided with an arc-shaped groove into which the L-shaped locking tongue 1212 extends, and the L-shaped locking tongue 1212 can engage with the track terminal fastening assembly 2 under the rotation of the operating lever 1213. That is, the locking mechanism 12 only requires the power connecting shaft 11 to be inserted into the track terminal fastening assembly 2, and the operating lever 1213 to be slid left and right to realize the quick assembly and disassembly of the curtain opening and closing control host 1, which is easy and convenient.

[0039] The power connection shaft 11 passes through the locking mechanism 12. Its upper end is used to insert into the connection hole of the track terminal fastening assembly 2 and connect to the drive wheel of the concealed track. The lower end of the power connection shaft 11 is used to connect to the clutch cam of the clutch mechanism 13 and is controlled by it to rotate, thereby driving the drive wheel of the concealed track to rotate and realize the opening and closing of the curtain.

[0040] See attached document Figure 3 , 7 As shown in Figure 8, the clutch mechanism 13 includes an encoder disk 131, a clutch cam 132, a magnetic bead 133, a bearing cover 134, and a rigid bearing 135. The bottom of the encoder disk 131 has a concave cavity 1311. The bearing cover 134 forms a closure around the lower part of the concave cavity 1311. The upper part of the clutch cam 132 is configured as a cam structure 1321 with two opposing protrusions. Both the cam structure 1321 and the magnetic bead 133 are located within the concave cavity 1311 of the encoder disk 131. The lower part of the clutch cam 132 passes through the central hole of the bearing cover 134 and connects to the drive mechanism 14, which drives it. The inner wall of the concave cavity 1311 of the encoder disk 131 has an arc-shaped groove 1312 that matches the magnetic bead 133, allowing the magnetic bead 133 to engage when the clutch cam 132 rotates under the drive mechanism 14. At this time, the clutch cam 132 and the encoder disk 131 are connected as one unit through the magnetic bead 133, enabling the clutch cam 132 to drive the encoder disk 131 to rotate, which in turn drives the power connecting shaft 11 to rotate, realizing the electric opening and closing of the curtain. The rigid bearing 135 is located at the lower part of the bearing cover 134, and the outer diameter of the rigid bearing 135 is smaller than the inner diameter of the concave cavity of the encoder disk 131. It is used to attract the magnetic bead 133 when the clutch cam 132 is not rotating, causing it to detach from the arc-shaped groove 1312, realizing the separation of the clutch cam 132 and the encoder disk 131, that is, the output power is cut off, and the encoder disk 131 can rotate freely. At this time, the curtain can be manually pulled to realize the manual opening and closing of the curtain.

[0041] In this embodiment, four evenly distributed arc-shaped grooves 1312 are provided on the inner sidewall of the concave cavity 1311 of the encoder disk 131, as shown in the attached figure. Figure 8 As shown. The inner cavity 1311 of the encoder disk 131 includes two magnetic beads 133, which are respectively disposed on both sides of the cam structure 1321. This structure enables the clutch mechanism 13 to start the rotation of the power connection shaft 11 with only a maximum rotation of 90 degrees, and the response is sensitive and fast.

[0042] The drive mechanism 14 drives the clutch cam 13 to rotate under the control of the electronic control mechanism 15.

[0043] For details, please refer to the appendix. Figure 3 , 5 As shown in Figure 10, the drive mechanism 14 includes a motor 141 and a gear transmission mechanism. The gear transmission mechanism includes a worm 142, a double-layer gear 143, a first bevel gear 144, and a second bevel gear 145. The worm 142 is fixed to the output shaft 1411 of the motor 141 and rotates with it. One layer of the double-layer gear 143 is a helical gear that meshes with the worm 142, and the other layer of gear 1432 is a straight gear that meshes with the first bevel gear 144. The first bevel gear 144 is a vertically arranged double-layer gear, and the second bevel gear 145 is a horizontal bevel gear that meshes with the first bevel gear 144. The upper part of the second bevel gear 145 is splined to the lower part of the clutch cam 132, which is driven by the motor 141 to rotate through the worm 142, the double-layer gear 143, and the first bevel gear 144, thereby driving the clutch cam 132 to rotate.

[0044] More specifically, as shown in the appendix Figure 3 and 4 As shown, the gear transmission mechanism is mounted on the gear fixing plate 146. The gear fixing plate 146 is provided with a clearance hole through which the motor output shaft 1411 passes and a shaft bracket 147 for fixing each gear. The first bevel gear 144 and the double-layer gear 143 are fixed on the shaft bracket 47 by an iron shaft 148.

[0045] More preferably, the upper end of the motor output shaft 1411 rotatably passes through the shaft support 147 and is inserted into the central hole of the second bevel gear 145. Both the shaft support 147 and the central hole of the second bevel gear 145 are provided with oil-impregnated bushings 149 to achieve smooth rotation of the output shaft 1411. That is, the motor output shaft 1411 serves as the central axis for the second bevel gear 145 and the rigid bearing 135 and bearing cover 134 sleeved on its exterior. This structural design of the drive mechanism 14 not only ensures that all components rotate concentrically, guaranteeing their concentricity, but also saves space, greatly reducing the length and volume of the product, allowing the length of this device to be compressed to 130mm.

[0046] Furthermore, the encoder disk 131 is also provided with an encoder disk cover plate 136, and an infrared encoder plate 137 connected to the electronic control mechanism 15 is also provided between the encoder disk cover plate 136 and the encoder disk 131.

[0047] Please refer to the appendix. Figure 3 and 6As shown, the encoder cover plate 136 has a central flange 1361 through which the power connection shaft 11 passes. The ring 1211 is sleeved on the outer circumference of the central flange 1361 and rotates around the central flange 1361. The encoder cover plate 136 also has an elastic rocker 1362 for controlling the rotation of the operating lever 1213. The elastic rocker 1362 can ensure that the operating lever 1213 is fixed in the locked position, thereby improving the safety of the locking mechanism 12.

[0048] The upper part of the latch cover 122 is also provided with two positioning pins 1223, which are used to correspond to the positioning holes at the bottom of the track terminal fastening assembly 2 to prevent misalignment.

[0049] Four connecting posts 1224 are provided at the four corners of the lower part of the outer cover 122. After the four connecting posts 1224 pass through the encoder cover 136, they are fixedly connected to the connecting holes 1341 at the four corners of the bearing cover 134, so as to realize the combined installation of the locking mechanism 12 and the clutch mechanism 13.

[0050] See attached document Figures 3 to 5 As shown, the electronic control mechanism 15 includes a PCB main control board 151 and connected to it a microphone 152, a speaker 153, a power interface 154, and a network interface 155, used for electronically receiving and outputting control signals. The microphone 152 and speaker 153 enable voice-interactive control of the device, enhancing its intelligence. The power interface 154 can be connected to a 220V DC power adapter or the DC power of a lithium battery pack from an emergency portable power source. (See attached diagram) Figure 11 As shown, the concealed track curtain opening and closing control device in this embodiment also includes a mobile power supply 3 that can be snapped onto the bottom of the curtain opening and closing control host 1. The top of the mobile power supply 3 is provided with a retractable power output port 31. When the power output port 31 is extended, it is connected to the bottom power interface 154 of the curtain opening and closing control host 1.

[0051] In this embodiment, the outer casing 16 of the concealed track curtain opening and closing control device is made of plastic, which is not only easy to manufacture and low in cost, but also easy to assemble, and can overcome the signal shielding problem caused by the existing aluminum alloy casing.

[0052] This utility model features a concealed track curtain opening and closing control device that connects to the curtain track in a vertical configuration. Through improvements to its internal structure, it can easily achieve automatic switching between electric and manual opening and closing, and can also greatly shorten the length of the opening and closing main unit, making the final length of the main unit only 130mm. It is compact and exquisite, conducive to environmental arrangement, and meets market demand.

[0053] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes or alterations made by those skilled in the art using the above-disclosed technical content shall fall within the protection scope of the present utility model.
