Description

Technical Field

[0001] This invention relates to the field of smart home technology, specifically to a curtain opening and closing device. Background Technology

[0002] A new curtain opening and closing device has emerged on the market. This device eliminates the need to modify existing manual curtains; it can be directly installed on the curtain track to achieve automatic control of the curtains. Specifically, the device typically consists of a housing, a drive roller housed within the housing, and a mounting mechanism mounted on the housing. The drive roller extends out of the housing, and the mounting mechanism is installed on the curtain track, causing the drive roller to press against the bottom of the track. The rotation of the drive roller propels the device along the track, opening and closing the curtains as it moves.

[0003] Current curtain opening and closing mechanisms require different mounting mechanisms for different curtain tracks. However, existing curtain opening and closing mechanisms usually require a relatively complicated installation process to be installed on the curtain track, making installation inconvenient, especially since they cannot be installed with one hand.

[0004] Accordingly, a new technical solution is needed in this field to solve the above problems. Summary of the Invention

[0091] Preferred embodiments of this application will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of this application and are not intended to limit the scope of protection of this application.

[0092] It should be noted that in the description of this application, the terms "upper," "lower," "left," "right," "front," "rear," "vertical," "horizontal," "inner," and "outer," which indicate directional or positional relationships, are based on the directional or positional relationships shown in the accompanying drawings. These terms are used merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," "third," "fourth," "fifth," and "sixth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0093] Furthermore, it should be noted that, in the description of this application, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0094] First refer to Figures 1 to 4 The general implementation of the curtain opening and closing device of this application is described in conjunction with the fact that the curtain track is a U-shaped track.

[0095] like Figures 1 to 4 As shown, to address the inconvenience of installation in existing curtain opening and closing devices, the curtain opening and closing device of this application includes a housing 1, a drive roller assembly 2, a power supply assembly 3, a mounting mechanism 5, and a switch part 4. A through hole is formed at the top of the housing 1. The drive roller assembly 2 includes a drive mechanism and a drive wheel (neither shown in the figure). The drive mechanism drives the drive wheel to rotate. The drive wheel is installed inside the housing 1 and partially extends out through the through hole. The power supply assembly 3 is disposed inside the housing 1 and is used to supply power to the drive mechanism.

[0096] The mounting mechanism 5 includes a first bracket 51, a second bracket 52, a first driven wheel 53, and a second driven wheel 54. The first driven wheel 53 is rotatably mounted on the first bracket 51, and the second driven wheel 54 is rotatably mounted on the second bracket 52. At least one of the first bracket 51 and the second bracket 52 is configured to pivot relative to the housing 1, which allows the mounting mechanism 5 to switch between an installation position and a use position.

[0097] The switch part 4 is pivotally connected to the housing 1, and the switch part 4 is configured to switch between a first position and a second position. When the switch part 4 is switched from the first position to the second position, the mounting mechanism 5 can switch from the use position to the installation position; when the switch part 4 is switched from the second position to the first position, the mounting mechanism 5 can switch from the installation position back to the use position.

[0098] In the static state, the curtain opening and closing device of this application has the switch part 4 in the closed position and the hanging mechanism 5 in the use position. In use, firstly, the switch part 4 is switched from the first position to the second position, and simultaneously, the hanging mechanism 5 switches from the use position to the installation position. Next, the curtain opening and closing device is moved to the installation position, and the switch part 4 is reset from the second position to the first position. At this time, the hanging mechanism 5 switches from the installation position back to the use position, thus the device is hung on the U-shaped track 7. After hanging, the drive wheel in the drive roller assembly 2 presses against the lower side of the U-shaped track 7. Driven by the drive mechanism, the drive wheel rotates, and the friction between the drive wheel and the U-shaped track 7 enables movement on the U-shaped track 7. During movement, the curtain opening and closing device moves the curtain hooks on the U-shaped track 7, thereby achieving automatic opening and closing of the curtain.

[0099] As can be seen from the above description, the curtain opening and closing device of this application has the advantage of convenient installation by setting the switch part 4. Specifically, by switching the switch part 4 from the first position to the second position, the hanging mechanism 5 can be switched from the use position to the installation position. At this time, the curtain opening and closing device can be easily moved to the installation position on the curtain track. When the switch part 4 returns to the first position from the second position, the hanging mechanism 5 switches from the installation position to the use position, and the curtain opening and closing device can be installed on the curtain track. In other words, the installation of the device can be achieved through a simple switching action, greatly simplifying the installation process of the curtain opening and closing device.

[0100] The following is further reference Figures 1 to 6 A preferred embodiment of the curtain opening and closing device of this application will be described.

[0101] First see Figure 3 The outer casing 1 includes a front casing 11 and a rear casing 12, which are installed together by snap-fit, screw-fit, or other means. Each of the front casing 11 and rear casing 12 has a notch (not shown in the figure) at its top. After installation, a cavity is formed inside the outer casing 1, and the two notches form a through hole. The drive roller assembly 2 includes a drive mechanism and a drive wheel. The drive mechanism is a motor, and the motor's output shaft is connected to the drive wheel via a transmission assembly, such as directly or through a transmission component. The drive roller assembly 2 is installed in the cavity of the outer casing 1. After installation, the drive wheel extends through the aforementioned through hole and can rotate relative to the outer casing 1. It should be noted that the form and principle of the drive roller assembly 2 are already quite common in the prior art. This application does not limit the specific form of the drive roller assembly 2; any drive roller assembly 2 that meets the installation conditions of this application can be used in this application.

[0102] See also Figure 3The power supply component 3 includes a battery 31 and a circuit board 32. The battery 31 can be a lithium battery, which is connected to the circuit board 32. The circuit board 32 is connected to the motor. The battery 31 supplies power to the motor, and the circuit board 32 controls the start and stop of the motor. The above connection and control methods are commonly used in the field and will not be described in detail. It should be noted that in this application, there is no limitation on the method of receiving the motor start and stop command. It can be issued by a device such as a remote control or mobile terminal that is connected to the circuit board 32, or it can be issued through a physical button set in the housing 1, or through a button or switch set in any indoor location and connected to the circuit board 32. The communication connection with the circuit board 32 can be wired or wireless. The wireless communication method can be, but is not limited to, Bluetooth, infrared, WiFi, ZigBee, etc. The mobile terminal can be, for example, a mobile phone, smart home device, wearable device, smart mobile device, virtual reality device, or any combination thereof. Of course, when using any of the above connection methods, the circuit board 32 needs to be equipped with corresponding modules. The setting and connection method of these modules are conventional technologies in the field and will not be described in detail.

[0103] See Figure 2 and Figure 3 The switch part 4 includes clamps. In this application, two clamps are provided, namely a first clamp 41 and a second clamp 42. The first clamp 41 and the second clamp 42 are pivotally mounted on opposite first and second sides of the outer casing 1 via a pivot. In this application, the first clamp 41 is pivotally connected to the front side of the front casing 11 via a first pivot 61, and the second clamp 42 is pivotally connected to the rear side of the rear casing 12 via a second pivot 62.

[0104] Specifically, taking the first clamping plate 41 as an example, it is composed of a first body 411 and a first cover 412, which are combined by snap-fitting, screwing, or other means. A first shallow groove 4121 is provided at the lower part of the outer side of the first cover 412 (i.e., the side facing away from the outer shell 1 after installation). The first shallow groove 4121 is elongated and extends along the width direction of the first cover 412 (i.e.,...). Figure 3 Extending in the left-right direction. A first receiving groove 4112 is provided on the inner side of the first body 411 (i.e., the side facing the outer shell 1 after installation). The first receiving groove 4112 is approximately rectangular, and a first bearing 4111 is provided at each end of the middle of the first receiving groove 4112. Each first bearing 4111 has a first shaft hole (not shown). A first through groove 114 is provided in the middle of the front side of the front shell 11, extending along the width direction of the front shell 11. Figure 3Extending in the left-right direction, the first through groove 114 is provided with two second bearing seats 113, each of which has a second shaft hole. After installation, the first rotating shaft 61 passes through the first shaft hole, the second shaft hole, the second shaft hole and the first shaft hole in sequence, and then pivotally connects the first clamping plate 41 to the front shell 11. The two first bearing seats 4111 are pivotally located in the first through groove 114.

[0105] Similarly, the second clamping plate 42 is composed of a second body 421 and a second cover 422, which are joined together by snap-fitting, screwing, or other means. A second shallow groove (not shown in the figure) is provided on the lower part of the outer surface of the second cover 422 (i.e., the side facing away from the outer shell 1 after installation). The second shallow groove is elongated and extends along the width direction of the second cover 422 (i.e.,...). Figure 3 Extending in the left-right direction. A second receiving groove 4212 is provided on the inner side of the second body 421 (i.e., the side facing the outer casing 1 after installation). The second receiving groove 4212 is approximately rectangular. A third bearing 4211 is provided at each end of the middle of the second receiving groove 4212, and each third bearing 4211 has a third shaft hole (not shown). A second through groove 124 is provided in the middle of the rear side of the rear casing 12, extending along the width direction of the rear casing 12. Figure 3 Extending in the left-right direction, the second through groove 124 is provided with two fourth shaft seats (not shown), each of which has a fourth shaft hole. After installation, the second rotating shaft 62 passes through the third shaft hole, the fourth shaft hole, the fourth shaft hole and the third shaft hole in sequence, and then pivotally connects the second clamping plate 42 to the rear shell 12. The two third shaft seats 4211 are pivotally located in the second through groove 124.

[0106] Furthermore, the portion of the front side of the front housing 11 below the second shaft hole and the portion of the rear side of the rear housing 12 below the fourth shaft hole are along the vertical direction (i.e. Figure 3 The top and bottom sections gradually narrow from top to bottom and transition into the bottom arc.

[0107] See Figure 1 and Figure 2After being set up, when viewed from the side of the device, when the switch part 4 is in the closed position, the portion of the first clamping plate 41 above the first shaft seat 4111 and the portion of the second clamping plate 42 above the third shaft seat 4211 form the "clamping head" portion of the clamp. The portion of the first clamping plate 41 below the first shaft seat 4111 and the portion of the second clamping plate 42 below the third shaft seat 4211 form the "handle" portion of the clamp. When an external force is applied to the "handle", the first clamping plate 41 and the second clamping plate 42 pivot around the first rotating shaft 61 and the second rotating shaft 62 to the open position (i.e., the second position), and the "clamping head" portion opens relative to the top of the outer shell 1. At this time, the front side of the front shell 11 and the rear side of the rear shell 12 are respectively accommodated in the first receiving groove 4112 and the second receiving groove 4212. When the external force is removed, the first clamping plate 41 and the second clamping plate 42 pivot around the first rotating shaft 61 and the second rotating shaft 62 respectively to a closed position relative to the outer shell 1 (i.e., the first position), at which time the "clamping head" part is closed relative to the top of the outer shell 1.

[0108] Continue to refer to Figure 3 The curtain opening and closing device also includes a second elastic element 43 and a third elastic element 44. The second elastic element 43 is configured to store elastic potential energy when the first clamping plate 41 pivots from the closed position to the open position under external force, and releases this elastic potential energy after the external force is removed, thus causing the first clamping plate 41 to pivot from the open position to the closed position. The third elastic element 44 is configured to store elastic potential energy when the second clamping plate 42 pivots from the closed position to the open position under external force, and releases this elastic potential energy after the external force is removed, thus causing the second clamping plate 42 to pivot from the open position to the closed position. Specifically, both the second elastic element 43 and the third elastic element 44 are torsion springs. Taking the third elastic element 44 as an example, the torsion spring is sleeved on the second rotating shaft 62, and the two protruding ends of the torsion spring respectively abut against the second receiving groove 4212 and the rear side of the rear shell 12. The second elastic element 43 is configured similarly and will not be described further.

[0109] See Figure 3 For each mounting mechanism 5, the top surface of the outer shell 1 has an extension hole, the first side surface has a first sliding hole 112, and the second side surface has a second sliding hole 122. Specifically, the top surface of the front shell 11 has two first notches 111, and the top surface of the rear shell 12 has two second notches 121. After installation, the two first notches 111 and the two second notches 121 form two extension holes. The upper part of the front side surface of the front shell 11 has two first sliding holes 112, which are rectangular elongated holes, and the two first sliding holes 112 are arranged side by side along the width direction of the front shell 11. The upper part of the rear side surface of the rear shell 12 has two second sliding holes 122, which are also rectangular elongated holes, and the two second sliding holes 122 are arranged side by side along the width direction of the rear shell 12.

[0110] See Figure 3 and Figure 4 There are two hooking mechanisms 5. The two hooking mechanisms 5 are arranged on both sides of the drive wheel along the rolling direction of the drive wheel (i.e. the extension direction of the U-shaped track 7). Each hooking mechanism 5 includes a first bracket 51, a second bracket 52, a first driven wheel 53, a second driven wheel 54 and a first elastic element 55.

[0111] Specifically, a pivot 63 is provided inside the outer shell 1. In this application, the pivot 63 is located between the front shell 11 and the rear shell 12, for example, on the left and right sides of the front shell 11 (i.e., Figure 3 The front shell 11 and rear shell 12 have semi-circular holes on their left and right sides respectively. After the front shell 11 and rear shell 12 are fastened together, the two pairs of semi-circular holes form two round holes at the seam between them. The two ends of the pivot shaft 63 pass through these two round holes. In other embodiments, C-shaped support grooves can be formed inside the front shell 11 and rear shell 12 to hold the pivot shaft 63 in place. In any case, as long as the pivot shaft 63 can be effectively positioned between the front shell 11 and rear shell 12, it is acceptable.

[0112] The first bracket 51 has a first pivot hole 511 at its bottom end, which is fitted onto a pivot shaft 63. The upper end of the first bracket 51 is a free end, and a first driven wheel 53 is rotatably mounted on the upper end of the first bracket 51. After installation, the bottom end of the first bracket 51 pivots around the pivot shaft 63, and the upper end of the first bracket 51 extends out through the extension hole. Similarly, the second bracket 52 has a second pivot hole 521 at its bottom end, which is fitted onto a pivot shaft 63. The upper end of the second bracket 52 is a free end, and a second driven wheel 54 is rotatably mounted on the upper end of the second bracket 52. After installation, the bottom end of the second bracket 52 pivots around the pivot shaft 63, and the upper ends of the second bracket 52 and the first bracket 51 extend out through the same extension hole.

[0113] The first elastic element 55 is configured to store elastic potential energy when the mounting mechanism 5 is in the installed position. Specifically, a first connecting post 512 is provided on the first bracket 51, a second connecting post 522 is provided on the second bracket 52, the first connecting post 512 and the second connecting post 522 extend in a direction away from each other, a third connecting post 125 is provided on the inner side of the rear shell 12, and a fourth connecting post 116 is provided on the inner side of the front shell 11. The first elastic element 55 is a compression spring, and two are provided in each mounting mechanism 5. The two ends of one compression spring are respectively sleeved on the first connecting post 512 and the third connecting post 125, and the two ends of the other compression spring are respectively sleeved on the second connecting post 522 and the fourth connecting post 116. After installation, when the first bracket 51 pivots toward the rear shell 12 and the second bracket 52 pivots toward the front shell 11, the two compression springs store elastic potential energy. When this elastic potential energy is released, it can cause the first bracket 51 and the second bracket 52 to pivot in opposite directions.

[0114] See Figures 3 to 6 A first protrusion 513 is provided on the side of the first bracket 51 facing the front shell 11, and a first push rod 4113 is provided on the inner side of the first body 411. The first protrusion 513 is a semi-circular protrusion, and the end of the first push rod 4113 is a semi-circular surface. When the first clamping plate 41 pivots from the position open relative to the outer shell 1 to the position closed relative to the outer shell 1, the first push rod 4113 passes through the first sliding hole 112 and abuts against the first protrusion 513, thereby pushing the first bracket 51 to pivot. Similarly, a second protrusion 523 is provided on the side of the second bracket 52 facing the rear shell 12, and a second push rod 4213 is provided on the inner side of the second body 421. The second protrusion 523 is a semi-circular protrusion, and the end of the second push rod 4213 is a semi-circular surface. When the second clamping plate 42 pivots from the position open relative to the outer shell 1 to the position closed relative to the outer shell 1, the second push rod 4213 passes through the first sliding hole 112 and abuts against the second protrusion 523, thereby pushing the second bracket 52 to pivot.

[0115] The following is combined Figure 1 , Figure 2 , Figure 5 and Figure 6 The installation process of the curtain opening and closing device of this application is described.

[0116] like Figure 2 , Figure 6As shown, when the curtain opening and closing device is in a stationary state, the switch part 4 is in the first position. At this time, the first clamping plate 41 and the second clamping plate 42 are respectively pressed against the front side of the front shell 11 and the rear side of the rear shell 12 under the action of the torsion spring. The top of the first bracket 51 is located at the second notch 121 under the pressure of the first top rod 4113, and the top of the second bracket 52 is located at the first notch 111 under the pressure of the second top rod 4213. At this time, the compression spring stores elastic potential energy, and the hanging mechanism 5 is in the use position.

[0117] like Figure 1 , Figure 5 As shown, when the curtain opening / closing device needs to be installed on the U-shaped track 7, the user first pinches the shallow grooves of the two clamps with one hand and applies force to the first clamp 41 and the second clamp 42 simultaneously. Under the action of force, the two clamps pivot along their respective axes to the open position relative to the outer shell 1, and the two torsion springs store elastic potential energy respectively. At the same time, the top of the first bracket 51 pivots towards the first notch 111 under the release of the elastic potential energy of the compression spring, and the top of the second bracket 52 pivots towards the second notch 121 under the release of the elastic potential energy of the compression spring. The first driven wheel 53 and the second driven wheel 54 approach each other and are roughly on the same straight line along the length of the U-shaped track 7, that is, the hanging mechanism 5 switches from the use position to the installation position. At this time, the user can lift the curtain opening / closing device to the installation position of the U-shaped track 7, so that the first driven wheel 53 and the second driven wheel 54 enter the track through the gap on the bottom surface of the U-shaped track 7.

[0118] Next, refer to Figure 2 , Figure 6 After being lifted to the installation position, the user releases the force applied to the two clamps. Driven by the torsion spring, the first clamp 41 and the second clamp 42 pivot along their respective axes to a closed position relative to the outer shell 1. At the same time, the first push rod 4113 presses against the first protrusion 513, causing the top of the first support rod to pivot to the second notch 121, and the second push rod 4213 presses against the second protrusion 523, causing the top of the second support rod to pivot to the first notch 111, until the first clamp 41 and the second clamp 42 are respectively tightly attached to the front side of the front shell 11 and the rear side of the rear shell 12. The first driven wheel 53 and the second driven wheel 54 move away from each other and press against a guide rail inside the U-shaped track 7, that is, the hanging mechanism 5 switches from the installation position to the use position. At this time, the curtain opening and closing device is hung on the U-shaped track 7. In addition, the drive wheel presses against the lower side of the U-shaped track 7, and the installation is completed.

[0119] Those skilled in the art will understand that although the above embodiments do not describe in detail how the drive roller assembly 2 presses against the lower side of the U-shaped track 7, this does not mean that this application cannot be implemented. On the contrary, in the prior art, there are many different solutions for how the drive roller assembly 2, especially the drive wheel, presses against the lower side of the U-shaped track 7 after the curtain opening and closing device is installed, and those skilled in the art can flexibly choose based on the actual product. For example, a spring / spring sheet can be set below the drive roller assembly 2 to achieve the drive wheel pressing against the U-shaped track 7; another example is that the hanging mechanism 5 can be elastically connected to the outer shell 1, etc.

[0120] The advantages of the above-described arrangement are as follows: by setting two clamping plates, the curtain opening and closing device of this application is easy to use. Users can install and disassemble the device simply by operating it like a regular clamp, greatly simplifying the installation process of the curtain opening and closing device. Furthermore, the symmetrical arrangement of the first clamping plate 41 and the second clamping plate 42 on both sides of the outer casing 1 also ensures that the curtain opening and closing device, after installation, has advantages such as uniform force distribution, smooth operation, and firm clamping.

[0121] By making both the first bracket 51 and the second bracket 52 pivotable, both the first driven wheel 53 and the second driven wheel 54 can be moved, reducing the force applied by the user and making installation easier.

[0122] By setting the first protrusion 513 and the second protrusion 523 as semi-circular protrusions, and setting the ends of the first push rod 4113 and the second push rod 4213 as semi-circular surfaces, the pivot stability of the first bracket 51 and the second bracket 52 can be improved, and the ease of disassembly and assembly of the device can be enhanced.

[0123] By setting the first elastic element 55, when the switch part 4 pivots to the open position, the hooking mechanism 5 can automatically switch to the installation position, and can also apply a certain degree of pressure to the first clamping plate 41 and the second clamping plate 42 to assist in opening the switch part 4 and save the user from applying force.

[0124] By opening a first receiving groove 4112 and a second receiving groove 4212 on the inner sides of the first clamping plate 41 and the second clamping plate 42 respectively, and setting a first bearing seat 4111 in the first receiving groove 4112 and a third bearing seat 4211 in the second receiving groove 4212, and setting a first through groove 114 and a second through groove 124 on both sides of the outer casing 1 respectively, and setting a second bearing seat 113 and a fourth bearing seat in the first through groove 114 and the second through groove 124 respectively, the overall thickness of the device can be reduced, making it convenient for users to assemble and disassemble.

[0125] By gradually narrowing the outer side of the front shell 11 below the second shaft hole and the rear side of the rear shell 12 below the fourth shaft hole in the vertical direction from top to bottom, and in conjunction with the setting of the receiving groove, a larger space can be reserved for the pivoting of the first clamping plate 41 and the second clamping plate 42, so that the two clamping plates have a larger opening angle and are convenient for installation.

[0126] By opening a first shallow groove 4121 and a second shallow groove on the lower outer side of the first clamping plate 41 and the second clamping plate 42 respectively, it is convenient for the user to apply force and reduce the difficulty of operation.

[0127] By setting the second elastic element 43 and the third elastic element 44, the two clamping plates can automatically rebound, reducing the difficulty of installation; and after installation, the two elastic elements can improve the stability of the device and prevent the two clamping plates from loosening.

[0128] It should be noted that the above preferred embodiments are merely illustrative of the principles of this application and are not intended to limit the scope of protection of this application. Without departing from the principles of this application, those skilled in the art can adjust the above settings to make this application applicable to more specific application scenarios.

[0129] For example, although the above embodiments are described in conjunction with the switch part 4 having two clamps and the first bracket 51 and the second bracket 52 in the hanging mechanism 5 being pivotally mounted, this is only a more preferred embodiment of this application. Without departing from the principle of this application, those skilled in the art can adjust the above embodiments, as long as the adjusted technical solution can achieve the action mode of "when the switch part 4 pivots from the closed position to the open position, the hanging mechanism 5 can switch from the use position to the installation position; when the switch part 4 pivots from the open position to the closed position, the switch part 4 can drive the hanging mechanism 5 to switch from the installation position to the use position".

[0130] For example, in one embodiment, with other settings remaining unchanged, the switch part 4 can be equipped with only one clamping plate. Correspondingly, the first bracket 51 in the hanging mechanism 5 is pivotally mounted, and the second bracket 52 is fixed relative to the outer shell 1, such as being integrally formed with the outer shell 1 or being snapped inside the outer shell 1. At this time, when the clamping plate pivots to the open position, the first bracket 51 pivots toward the first notch 111, realizing the switching of the hanging mechanism 5 from the use position to the installation position. When the clamping plate pivots to the closed position, the push rod on the inner side of the clamping plate presses against the protrusion on the first bracket 51, causing the first bracket 51 to pivot toward the second notch 121, realizing the switching of the hanging mechanism 5 from the installation position to the use position. Of course, in this alternative embodiment, with the first bracket 51 being pivotable, two clamping plates can also be provided simultaneously, except that only one of the two clamping plates is used in conjunction with the first bracket 51.

[0131] In another alternative embodiment, the bracket and the clamping plate can be connected by a transmission component, so that the pivoting of the clamping plate can drive the pivoting of the bracket. Taking the first clamping plate 41 and the first bracket 51 as an example, the first clamping plate 41 can be provided with a hinge hole, and the first bracket 51 is provided with a corresponding second hinge hole. The first hinge hole and the second hinge hole are connected by a transmission rod, with both ends of the transmission rod hinged to the first hinge hole and the second hinge hole, respectively. In this way, during the pivoting process of the first clamping plate 41, the first slider can be pivoted by the transmission rod, realizing the switching of the hanging mechanism 5 between the installation position and the use position.

[0132] For example, in another alternative embodiment, the mounting mechanism 5 can be installed not only inside the housing 1, but also outside the housing 1. For example, a pivot shaft can be provided on the top of the housing 1, and the first bracket 51 and the second bracket 52 can be pivotally mounted on the pivot shaft.

[0133] For example, in one possible implementation, the mounting mechanism 5 may be provided as a single unit. In this case, the first bracket 51 and the second bracket 52 in the mounting mechanism 5 may be provided on one side of the drive wheel or on both sides of the drive wheel.

[0134] For example, in one possible implementation, although the above embodiments are described with the outer shell 1 comprising a front shell 11 and a rear shell 12, this structural form is not unique. Those skilled in the art can adjust the specific structure of the outer shell 1 so that the adjusted technical solution is applicable to more specific application scenarios. For example, the outer shell 1 can also be configured as a one-piece structure, a split structure, etc.

[0135] For example, in an alternative embodiment, the pivoting arrangement of the two clamping plates is not unique. Provided that the two clamping plates can pivot relative to the outer casing 1, those skilled in the art can adjust their specific arrangement. For instance, the two clamping plates can be pivotally mounted on opposite sides of the outer casing 1 via the same pivot axis. Specifically, with... Figure 3 Taking the orientation shown as an example, a common bearing can be set at the middle of the upper edge of each of the left and right sides of the outer casing 1, and then the bearings of the two clamping plates located on the same side can be pivotally connected to the common bearing simultaneously. More specifically, located in Figure 3 The first bearing seat 4111 and the third bearing seat 4211 on the left side are pivotally connected to a common bearing seat located at the center of the upper edge of the left side of the housing 1 via a short shaft. Figure 3 The first bearing seat 4111 and the third bearing seat 4211 on the right side are pivotally connected to a common bearing seat located at the middle of the upper edge of the right side of the housing 1 via another short shaft.

[0136] For example, in another alternative embodiment, the above embodiment is described in conjunction with the installation of a power supply component 3 inside the housing 1. However, this embodiment is not restrictive, and those skilled in the art can choose whether or not to install the power supply component 3, and can also adjust the specific installation method of the power supply component 3. For example, in some application scenarios, the curtain opening and closing device may not have a power supply component 3, but instead be powered by an external power source, such as a power bank or an external solar panel 31. In this case, only a corresponding interface needs to be provided on the housing 1. Alternatively, if a power supply component 3 is installed, the power supply component 3 may include a circuit board 32 and a battery compartment for holding dry cell batteries 31.

[0137] For example, in another alternative embodiment, the first elastic element 55 may be a leaf spring or an elastic rubber block in addition to a compression spring. This substitution of the specific form of the first elastic element 55 does not deviate from the principle of this application.

[0138] For example, in another alternative embodiment, the second elastic element 43 and the third elastic element 44 can be replaced by other parts besides torsion springs. In one possible embodiment, one or both of the second elastic element 43 and the third elastic element 44 can be compression springs, with the two ends of the compression springs abutting between the clamping plate and the outer casing 1, respectively.

[0139] For example, although the pivoting action of the first support 51 is achieved by setting a first protrusion 513 on the first support 51 and setting a first push rod 4113 on the inner side of the first clamping plate 41 in the above embodiment, this setting method is not unique. In other embodiments, those skilled in the art can adjust the specific setting method, as long as the pivoting of the first support 51 can be achieved. For example, under the premise of setting both the first protrusion 513 and the first push rod 4113, the first protrusion 513 can be made to extend out of the first sliding hole 112 and abut against the first push rod 4113; or only the first protrusion 513 or only the first push rod 4113 can be set. When only the first protrusion 513 is set, the first protrusion 513 extends out of the first sliding hole 112 and can abut against the inner side of the first clamping plate 41. When only the second push rod 4213 is set, the second push rod 4213 can be made to extend into the first sliding hole 112 and abut against the first support 51. Similarly, the second bracket 52 and the second top rod 4213 can also be adjusted in the same way as described above, without further explanation.

[0140] For example, while ensuring that the curtain opening and closing device has a housing 1, a drive roller assembly 2, and a switch part 4, and that the hanging mechanism 5 has a first bracket 51, a second bracket 52, a first driven wheel 53, and a second driven wheel 54, other components or structures in the above embodiments can be selectively modified or omitted by those skilled in the art. For instance, the first elastic element 55 of the hanging mechanism 5 can be omitted, and the first bracket 51 and the second bracket 52 can be pivotally connected to the pivot hole in the housing 1 via a pivot shaft 63; the structures such as the first receiving groove 4112, the second receiving groove 4212, the first shallow groove 4121, the second shallow groove, and the narrowing of the side of the housing 1 can be modified or omitted.

[0141] Of course, the alternative implementation methods described above, as well as the alternative implementation methods and preferred implementation methods, can be used in combination to create new implementation methods that are suitable for more specific application scenarios.

[0142] The following reference Figure 7 and Figure 8 This paper provides a brief introduction to the application of the curtain opening and closing device of this application to an I-shaped track.

[0143] like Figure 7 and Figure 8 As shown, unlike the preferred embodiment described above, the specific arrangement of the hanging mechanism 5 has been adjusted in this embodiment, so that the curtain opening and closing device can be applied to the I-shaped track 8.

[0144] Specifically, such as Figure 7 and Figure 8 As shown, in the mounting mechanism 5, both the first bracket 51 and the second bracket 52 can still pivot along the pivot axis 63. The difference is that in this embodiment, regardless of whether the mounting mechanism 5 is in the installation position or the use position, the first driven wheel 53 and the second driven wheel 54 are always facing each other. In the previous embodiment, the first driven wheel 53 and the second driven wheel 54 faced opposite directions. In actual manufacturing, only the top shapes of the first bracket 51 and the second bracket 52 need to be adjusted.

[0145] The installation process of the curtain opening and closing device in this embodiment will be briefly described below. Figure 7 As shown, when an external force is applied causing the first clamping plate 41 and the second clamping plate 42 to pivot open relative to the outer casing 1 to the open position, under the elastic force of the first elastic element 55, the top ends of the first bracket 51 and the second bracket 52 pivot towards the first notch 111 and the second notch 121 respectively, and the first driven wheel 53 and the second driven wheel 54 move away from each other, that is, the hanging mechanism 5 switches from the use position to the installation position. At this time, the user can lift the curtain opening and closing device to the installation position of the I-shaped track, so that the bottom surface of the I-shaped track 8 can enter the space between the first driven wheel 53 and the second driven wheel 54. Figure 8 As shown, when the external force is removed, the first clamping plate 41 and the second clamping plate 42 pivot relative to the outer shell 1 and close to the closed position. The first top rod 4113 presses against the first protrusion 513, causing the top of the first bracket 51 to pivot towards the second notch 121. The second top rod 4213 presses against the second protrusion 523, causing the top of the second bracket 52 to pivot towards the first notch 111. The first driven wheel 53 and the second driven wheel 54 approach each other and press against a guide rail at the bottom of the I-shaped track 8, that is, the hanging mechanism 5 switches from the installation position to the use position. At this time, the curtain opening and closing device is hung on the I-shaped track 8, and the installation is completed.

[0146] The following reference Figures 9 to 12 Other configurations of the first elastic element and the pivot shaft will be introduced.

[0147] First refer to Figure 9 , Figure 9 The diagram shows the state of the hooking mechanism 5 when the switch part 4 is in the second position. Without changing other configurations, the orientation of the first driven member 53 and the second driven wheel 54 can be changed. The first pivot hole 511 and the second pivot hole 521 are respectively located in the middle of the first bracket 51 and the second bracket 52. The first protrusion 513 and the second protrusion 523 are respectively located in the lower part of the first bracket 51 and the second bracket 52. A fifth connecting post 514 is located in the lower part of the first bracket 51, and a sixth connecting post 524 is located in the lower part of the second bracket, such that the fifth connecting post 514 and the sixth connecting post 524 extend in a direction close to each other. Then, the two ends of the compression spring are respectively sleeved on the fifth connecting post 514 and the sixth connecting post 524. In this way, the hooking mechanism 5 can also be switched between the installation position and the use position.

[0148] Next, refer to Figure 10 , Figure 10 The state of the hooking mechanism 5 when the switch part 4 is in the second position is shown. Without changing other configurations, the orientation of the first driven member 53 and the second driven wheel 54 can be changed. The first pivot hole 511 and the second pivot hole 521 are respectively located in the middle of the first bracket 51 and the second bracket 52. The first protrusion 513 and the second protrusion 523 are respectively located in the lower part of the first bracket 51 and the second bracket 52. Furthermore, the orientation and extension direction of the first socket post 512 and the second socket post 522 are interchanged, so that the two ends of one first elastic member 55 are respectively fitted onto the first socket post 512 and the fourth socket post 116, and the two ends of the other first elastic member 55 are respectively fitted onto the second socket post 522 and the third socket post 125. In this way, the first bracket 51 and the second bracket 52 can be pivoted by the first push rod 4113 and the second push rod 4213 pressing against the lower part of the first bracket 51 and the second bracket 52.

[0149] See Figure 11 Without changing other settings, two pivot shafts 63 can be installed inside the outer casing 1, one in the front casing 11 and one in the rear casing 12. The bottom ends of the first bracket 51 and the second bracket 52 are then pivotally connected to one of the pivot shafts 63. A fifth connecting post 514 is installed at the lower part of the first bracket 51, and a sixth connecting post 524 is installed at the lower part of the second bracket, with the fifth and sixth connecting posts 514 and 524 extending in a direction close to each other. The two ends of a compression spring are then respectively fitted onto the fifth and sixth connecting posts 514 and 524. In this way, by pivoting the first bracket 51 and the second bracket 52, the hanging mechanism 5 can be switched between the installation position and the usage position.

[0150] See Figure 12 Without changing other settings, two pivot shafts 63 can be installed inside the outer casing 1, one in the front casing 11 and one in the rear casing 12. Then, the bottom ends of the first bracket 51 and the second bracket 52 are pivotally connected to one of the pivot shafts 63 respectively. In this way, by pivoting the first bracket 51 and the second bracket 52 respectively, the hanging mechanism 5 can be switched between the installation position and the use position.

[0151] It should be noted that, although the above Figures 9 to 12 Only four possible implementations of the first elastic element 55 and the pivot shaft 63 are listed, but these are merely exemplary. Those skilled in the art can make other similar adjustments to the first elastic element 55 and the pivot shaft 63 based on specific application scenarios, and such adjustments do not deviate from the principles of this application.

[0152] Those skilled in the art will understand that the above-described settings and adjustments are also applicable to the curtain opening and closing device applied to the I-shaped track 8.

[0153] The following reference Figure 13 This paper will briefly introduce another configuration method of the switch section in this application.

[0154] like Figure 13As shown, unlike the preferred embodiment described above, the switch part 4 is specifically in the form of a button. In this embodiment, two buttons are provided: a first button 45 and a second button (not shown in the figure). The first button 45 is embedded in a first mounting hole 115 on the front side of the front housing 11, and a portion of the first button 45 extends into the interior of the front housing 11. The second button is embedded in a second mounting hole on the rear side of the rear housing 12, and a portion of the second button extends into the interior of the rear housing 12. The fourth elastic element is configured to store elastic potential energy when the first button 45 is pressed under external force, and to release this elastic potential energy and reset the first button 45 to its initial position when the external force is removed. Similarly, the fifth elastic element is configured to store elastic potential energy when the second button is pressed under external force, and to release this elastic potential energy and reset the second button to its initial position when the external force is removed. In other words, the initial position of the two buttons in the absence of external force is the first position of the switch part 4, and the position where the two buttons are pressed is the second position of the switch part 4.

[0155] In this embodiment, both the fourth and fifth elastic elements can be compression springs or elastic blocks. Positionally, the two ends of the fourth elastic element can abut against the first button 45 and the front housing 11, respectively, and the two ends of the fifth elastic element can abut against the second button and the rear housing 12, respectively. Alternatively, the fourth and fifth elastic elements can be arranged in a similar manner to the first elastic element 55 described above, such as the fourth elastic element being positioned between the first bracket 51 and the front housing 11, and the fifth elastic element being positioned between the second bracket 52 and the rear housing 12.

[0156] In the above-described configuration, the mounting mechanism 5 is configured slightly differently from the preferred embodiment. Specifically, the mounting mechanism 5 still uses the same components as in the preferred embodiment, but the difference is that when the mounting mechanism 5 is in the installation position, the first elastic element 55 is compressed to store elastic potential energy, and the two driven wheels are close to each other. In other words, when the switch part 4 moves from the first position to the second position, that is, when the two buttons are pressed under external force, the inner surfaces of the two buttons (or the push rods provided on the inner surfaces) respectively push the first bracket 51 and the second bracket 52 to pivot toward the first notch 111 and the second notch 121 (at this time, the first button 45 pushes the second bracket 52, and the second button pushes the first bracket 51). This pivoting causes the two driven wheels to move closer to each other, at which point the first elastic element 55 is compressed to store elastic potential energy, and the mounting mechanism 5 is in the installation position. When the external force is removed, the switch part 4 is reset from the second position to the first position. That is, when the external force is removed, the two buttons are lifted by the action of the fourth elastic element and the fifth elastic element respectively. At this time, the first bracket 51 and the second bracket 52 pivot to the second notch 121 and the first notch 111 respectively under the action of the release of the elastic potential energy of the first elastic element 55. At this time, the hooking mechanism 5 is in the use position.

[0157] In the above configuration, when an external force is applied to press the first button 45 and the second button, the first bracket 51 and the second bracket 52 pivot towards the first notch 111 and the second notch 121 respectively, driven by the first and second driven wheels 53 and 54. This causes the hanging mechanism 5 to switch from the usage position to the installation position, at which point the first elastic element 55 stores elastic potential energy. At this time, the user can lift the curtain opening / closing device to the installation position on the U-shaped track 7, allowing the first and second driven wheels 53 and 54 to enter the gap at the bottom of the U-shaped track 7. When the external force is removed, the first button 45 and the second button spring outward from the outer casing 1 under the release of the elastic potential energy of the compression spring. The first bracket 51 pivots towards the second notch 121 under the release of the elastic potential energy of the first elastic element 55. The second bracket 52 pivots towards the first notch 111 under the release of the elastic potential energy of the first elastic element 55. The first driven wheel 53 and the second driven wheel 54 move away from each other and press against a guide rail inside the U-shaped track 7. That is, the hanging mechanism 5 switches from the installation position to the use position. At this time, the curtain opening and closing device is hung on the U-shaped track 7, and the installation is completed.

[0158] In an alternative embodiment, the lengths of the first button 45 and the second button can be shortened, and a transmission plate can be provided between the first button 45 and the second bracket 52 to realize the transmission connection between the two. A transmission plate can also be provided between the second button and the first bracket 51 to realize the transmission connection between the two.

[0159] In an alternative embodiment, the first button 45 and the second button can be set on the outside of the housing 1 as a whole, and the first sliding hole 112 and the second sliding hole 122 can be retained. Then, by setting a top rod structure on the first button 45 and the second button, and extending the top rod structure into the housing 1 through the corresponding sliding hole to abut against the corresponding bracket, the switching between the use position and the installation position of the hanging mechanism 5 can also be realized.

[0160] In another alternative embodiment, while retaining the first sliding hole 112 and the second sliding hole 122, protrusions can be provided on the first bracket 51 and the second bracket 52, and the two protrusions can be extended through the corresponding sliding holes respectively. Then, the first button 45 and the second button are set on the outside of the housing 1 as a whole. The two brackets can be pivoted by pressing the protruding protrusions during the button press, thereby realizing the switching between the use position and the installation position of the hanging mechanism 5.

[0161] Of course, the extended technical solutions in the above preferred embodiments are also applicable to this embodiment. For example, when only one bracket can be pivotally mounted, only one button can be provided. Furthermore, the bracket and the button can also be connected by a hinge rod to achieve transmission.

[0162] It should be noted that although only two implementation methods are provided for the switch part 4 in this embodiment, those skilled in the art should understand that the contribution of this application to the prior art lies in adjusting the position of the hanging mechanism 5 through the simple switching action of the switch part 4, thereby realizing the installation of the device. Its protection scope should not be limited to the above two configuration forms of the switch part 4. Therefore, those skilled in the art can use other forms of switch part 4 to achieve the technical objectives of this application. For example, in possible implementations, the hanging mechanism 5 can also be driven by a lever, a lever block, etc.

[0163] Those skilled in the art will understand that although some embodiments described herein include certain features included in other embodiments but not others, combinations of features from different embodiments are intended to be within the scope of this application and form different embodiments. For example, any of the claimed embodiments in the claims of this application can be used in any combination.

[0164] The technical solutions of this application have been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of this application is obviously not limited to these specific embodiments. Without departing from the principles of this application, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the scope of protection of this application.
