[0002] Most electric curtains on the market are double-open and double-control or single-open. Single-open means that the curtain fabric is a whole piece. When opening or closing the curtain, the curtain fabric moves from one side of the window to the other side. The curtain fabric cannot be opened from the middle, and the control flexibility is low. Double-open and double-control means that the curtain fabric is divided into two pieces, and the opening and closing of the two pieces of curtain fabric are consistent. In other words, when opening the curtain, the two curtain fabrics move to both sides of the window at the same time; when closing the curtain, the two curtain fabrics move to the middle of the window at the same time. It cannot achieve the effect of one curtain opening and one curtain closing, and the control flexibility is still low. However, there is a problem of high cost to improve flexibility by changing the control program of the two curtains. Summary of the invention

[0003] The present application provides a transmission assembly, a transmission box, a transmission device, a driving device, a transmission system and a curtain assembly, so as to at least solve the technical problems of low control flexibility and high improvement cost of the curtain.

[0011] According to the fourth aspect of the embodiment of the present application, a driving device is provided, comprising a driver and the transmission assembly described above; the transmission assembly is arranged on the driving shaft; when the driver drives the first transmission member and the connecting member in the transmission assembly to rotate, the connecting member does not transmit driving force to the second transmission member.

[0012] According to a fifth aspect of the embodiments of the present application, a transmission system is provided, comprising a driver and the transmission device described above, wherein at least two drivers are provided, the two drivers comprising a first driver and a second driver, and transmission boxes are installed on the two drivers, the two transmission boxes are respectively a first transmission box connected to the first driver and a second transmission box connected to the second driver;

[0013] The first driver and the first transmission box are arranged at one end of the guide rail, and the second driver and the second transmission box are arranged at the other end of the guide rail; the first transmission member is reciprocatably arranged between the first transmission member of the first transmission box and the second transmission member of the second transmission box, and the second transmission member is reciprocatably arranged between the second transmission member of the first transmission box and the first transmission member of the second transmission box.

[0015] In an embodiment of the present application, the transmission assembly includes a connecting member, a first transmission member, and a second transmission member. After the transmission assembly is applied to the driving shaft of the driving body, the connecting member allows the driving force transmitted by the driving shaft to be transmitted to the first transmission member, but cannot be transmitted to the second transmission member, that is, the first transmission member can be driven by the driving shaft, so that when the driving shaft rotates, the first transmission member rotates, and the second transmission member does not rotate due to the rotation of the driving shaft. Based on this transmission assembly, the two curtains of the double-opening and dual-control curtain can move independently when being controlled. In other words, when it is necessary to control one of the curtains to move and the other not to move, the driving bodies of the two curtains can be started at the same time, or the driving bodies corresponding to the curtains can be started separately.

[0025] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0026] The existing double-opening dual-control electric curtains include two motors, each of which is used to drive a curtain to move. Its characteristic is that when the user remotely controls the curtain to open, the two motors are controlled at the same time, and each drives the curtain connected to it to move to the side of the window; when the remote control curtain is closed, the two motors are controlled at the same time, and each drives the curtain connected to it to move to the middle of the window. However, this control method has low flexibility and is difficult to meet the control needs of users. Therefore, if you want to improve the control flexibility of the curtains, you can improve the control program of the motor so that each motor can be controlled independently. However, this approach not only requires program development, but also requires modifying the remote control of the electric curtains, so that a button or program for independent control of a single motor is added to the remote control. That is, this method of improving control flexibility is costly.

[0027] Based on this, the present application provides a transmission assembly, which is used to drive and connect with the drive shaft 41 of the driver 4, such as Figure 1-5 As shown, the transmission assembly includes a connecting member 1, a first transmission member 2 and a second transmission member 3; the first transmission member 2 is provided with a first receiving hole 21, and the second transmission member 3 is provided with a second receiving hole 31;

[0028] The first transmission member 2 is sleeved on the driving shaft 41 through the first receiving hole 21 and is drivingly connected to the driving shaft 41;

[0029] The connecting member 1 is provided with a connecting hole 11, and the connecting member 1 is sleeved on the driving shaft 41 through the connecting hole 11 and is drivingly connected to the driving shaft 41;

[0030] The second transmission member 3 is sleeved on the connecting member 1 through the second accommodating hole 31 and is arranged in a non-driving cooperation with the connecting member 1;

[0031] The first transmission member 2 and the connecting member 1 are sleeved at different positions of the driving shaft 41 .

[0032] The connecting member 1, the first transmission member 2 and the second transmission member 3 included in the transmission assembly only need to be connected to the driver 4 when in use, that is, the transmission assembly can be produced independently of the driver 4 and does not need to be produced together with the driver 4. When the transmission assembly is in use, since the transmission assembly needs to be drivingly connected to the driving shaft 41 of the driver 4, the size of the transmission assembly can be adaptively modified according to the size of the driving shaft 41 to ensure that a driving connection relationship can be formed between the transmission assembly and the driving shaft 41.

[0033] Specifically, a driving connection refers to a connection relationship with driving force transmission. Taking the driving connection between the first transmission member 2 and the driving shaft 41 as an example, when the first transmission member 2 is sleeved on the driving shaft 41, the first transmission member 2 can be affected by the driving shaft 41, and can move directly or indirectly under the influence of the driving force transmitted by the driving shaft 41, which is regarded as a driving connection formed between the first transmission member 2 and the driving shaft 41. For example, after the first transmission member 2 is sleeved on the driving shaft 41, the driving shaft 41 and the first transmission member 2 are mutually engaged to form a whole, and when the driving shaft 41 rotates, the first transmission member 2 rotates synchronously with the driving shaft 41.

[0034] Correspondingly, non-driven fit refers to a fit relationship in which no driving force is transmitted. Taking the non-driven fit relationship formed by the second transmission member 3 being sleeved on the connecting member 1 as an example, since the connecting member 1 is drivingly connected to the drive shaft 41, when the drive shaft 41 rotates, the connecting member 1 will rotate due to the driving force transmitted by the drive shaft 41. However, at this time, the connecting member 1 cannot transmit the driving force to the second transmission member 3, so the second transmission member 3 is not affected by the driving force and does not rotate with the connecting member 1. For example, after the second transmission member 3 is sleeved on the connecting member 1, the two can generate relative motion. When the connecting member 1 is affected by other structures or its own gravity, the connecting member 1 rotates but the second transmission member 3 does not rotate due to the rotation of the drive shaft 41; or when the second transmission member 3 is affected by other structures or its own gravity, the second connecting member 3 rotates but the connecting member 1 does not rotate due to the rotation of the drive shaft 41.

[0035] When using the transmission assembly, the first transmission member 2 can be sleeved on the driving shaft 41 of the driver 4 first, and then the connecting member 1 can be sleeved on the driving shaft 41 of the driver 4; similarly, the connecting member 1 can be sleeved first, and then the first transmission member 2 can be sleeved. Figure 1 As shown in FIG. 1 , the first transmission member 2 is sleeved first, and then the connecting member 1 is sleeved, and finally the second transmission member 3 is sleeved on the connecting member 1. Figure 1 From the perspective of orientation, the first transmission member 2 is located below the second transmission member 3, so that the first transmission member 2 and the connecting member 1 are sleeved at different positions of the driving shaft 41.

[0036] When the driving shaft 41 of the driver 4 rotates, since the first transmission member 2 is drivingly connected to the driving shaft 41, the first transmission member 2 rotates along with the driving shaft 41, and the connecting member 1 also rotates along with the driving shaft 41, but since the connecting member 1 is non-drivingly matched with the second transmission member 3, the second transmission member 3 does not rotate due to the rotation of the driving shaft 41. This results in the first transmission member 2 being controlled by the driver 4, while the second transmission member 3 is not controlled by the driver 4.

[0037] According to the above content, the transmission assembly includes a connecting member 1. After the transmission assembly is applied to the driving shaft 41 of the driving body, the connecting member 1 prevents the driving force transmitted by the driving shaft 41 from reaching the second transmission member 3, but the first transmission member 2 can be driven by the driving shaft 41. When the driving shaft 41 rotates, the first transmission member 2 rotates, and the second transmission member 3 does not rotate due to the rotation of the driving shaft 41. Based on this transmission assembly, the two curtains of the double-opening and double-controlled curtain can move independently when being controlled. In other words, when it is necessary to control one of the curtains to move and the other curtain not to move, the driving bodies of the two curtains can be started at the same time, or the driving bodies corresponding to the curtains can be started separately. Since the transmission assembly is installed on the driving body, the curtain connected to the second transmission member 3 will not be driven by the driving body, so that the effect of one moving and one stationary of the two curtains is achieved, and the control flexibility is improved. At the same time, since the transmission assembly can be directly applied to the existing driving body, there is no need to modify the control program, which saves development time and reduces development costs.

[0038] In another embodiment of the present application, the cross-sectional shape of the second accommodating hole 31 and the cross-sectional outer ring shape of the connecting member 1 are designed to have no transmission function, so that the second transmission member 3 and the connecting member 1 are arranged in a non-driving cooperation.

[0039] Specifically, the hole has radial and axial directions, and the cross section of the hole refers to the surface after the hole is cut along the radial direction of the hole. Figure 4 Taking the orientation shown as an example, after the second receiving hole 31 is cut in the vertical direction, the vertical surface presented is the cross section of the second receiving hole 31 , and the shape of the surface is the cross-sectional shape of the second receiving hole 31 .

[0040] In one embodiment, when the cross-sectional shape of the second receiving hole 31 can make the shape formed by the outer circle of the cross-sectional shape of the connecting member 1 idle, the non-driven cooperation between the second transmission member 3 and the connecting member 1 can be achieved. For example, when the cross-sectional shape of the second receiving hole 31 is circular, and the cross-sectional shape of the outer circle of the connecting member 1 is also circular, the connecting member 1 cannot clamp the second transmission member 3 when rotating, so the connecting member 1 cannot transmit the driving force to the second transmission member 3, so there is no transmission effect between the two, and a non-driven cooperation is formed. For another example, when the cross-sectional shape of the second receiving hole 31 is square, the cross-sectional shape of the outer circle of the connecting member 1 is circular, and the circle is the inscribed circle of the square, the connecting member 1 cannot form a clamping relationship with the second transmission member 3 when rotating, causing the connecting member 1 to idle in the second receiving hole 31.

[0041] Through the above content, by designing the shape of the second accommodating hole 31 and the connecting member 1, the non-driven cooperation between the second transmission member 3 and the connecting member 1 is achieved without adding an additional mechanical structure, which helps to reduce costs and save space occupied by the transmission component.

[0042] In another embodiment of the present application, the cross-sectional shape of the first receiving hole 21 is a polygon that matches the cross-sectional shape of the drive shaft 41, and the cross-sectional shape of the connecting hole 11 is a polygon that matches the cross-sectional shape of the drive shaft 41;

[0043] The cross-sectional shape of the second receiving hole 31 is circular, and the cross-sectional outer circle shape of the connecting member 1 is adapted to the second receiving hole 31 .

[0044] Among them, polygon refers to a shape with multiple sides, such as a triangle, a quadrilateral, a hexagon, etc., while a circle is not a polygon. It should be noted that the polygon defined in this embodiment is intended to enable the drive shaft 41 to form a snap-fit ​​relationship with the first transmission member 2. Therefore, as long as the cross-sectional shape of the first receiving hole 21 and the cross-sectional shape of the drive shaft can enable the first transmission member 2 to form a snap-fit ​​relationship with the drive shaft 41, the shape is a polygon, such as an 8-shaped shape, an 0-shaped shape, etc. The cross-sectional shape of the first receiving hole 21 and the cross-sectional shape of the drive shaft 41 are both polygonal and mutually adapted, so that after the drive shaft 41 is inserted into the first receiving hole 21, each side of the drive shaft 41 corresponds to the corresponding side of the cross section of the first receiving hole 21, so that when the drive shaft 41 rotates, it will not idle in the first receiving hole 21, and then the drive shaft 41 drives the first transmission member 2 to rotate.

[0045] Similarly, since the connection member 1 and the drive shaft 41 are also drive-connected, the cross-sectional shape of the connection hole 11 also matches the cross-sectional shape of the drive shaft 41. Specifically, the cross-sectional shape of the first receiving hole 21 is the same as that of the connection hole 11, and the area is the same.

[0046] In one embodiment, the cross-sectional shape of the second accommodating hole 31 is circular, and the cross-sectional outer circle shape of the connecting member 1 is adapted to the second accommodating hole 31 , which means that the cross-sectional outer circle shape of the connecting member 1 is the same as the cross-sectional shape of the second accommodating hole 31 and has the same area.

[0047] Through the above, the adapted polygon is convenient for forming a snap-fit, so that the drive shaft 41 can be snap-fitted in the first receiving hole 21 and the connecting hole 11, realizing the driving connection between the drive shaft 41 and the first transmission member 2 and the driving connection between the drive shaft 41 and the connecting member 1. The second receiving hole 31 with a circular cross-sectional shape is convenient for forming a non-driving matching relationship with the adapted connecting member 1. This helps to reduce the difficulty of design and production.

[0048] In another embodiment of the present application, the first transmission member 2 and the second transmission member 3 are both gears.

[0049] That is to say, gear teeth are distributed on the outer circumference of the first transmission member 2 and the outer circumference of the second transmission member 3 .

[0050] Through the above content, the first transmission member 2 and the second transmission member 3 are designed as gears, which facilitates the first transmission member 2 and the second transmission member 3 to mesh with other gears. At the same time, due to the gear tooth design, it is also convenient for the first transmission member 2 and the second transmission member 3 to generate friction with structures such as transmission belts, thereby driving the transmission belt to rotate or following the transmission belt to rotate.

[0051] In another embodiment of the present application, the first transmission member 2 and the second transmission member 3 are arranged at different positions in the axial direction of the drive shaft 41 , and the second transmission member 3 is arranged closer to the end side of the drive shaft 41 than the first transmission member 2 .

[0052] In one embodiment, the first transmission member 2 and the second transmission member 3 are arranged along the axial direction of the drive shaft 41, that is, along the length direction of the drive shaft 41, and the second transmission member 3 is closer to the end side of the drive shaft 41. The drive shaft 41 extends from the driver 4 in a direction away from the driver 4, and the end side of the drive shaft 41 refers to the end away from the driver 4. Therefore, when assembling the transmission assembly and the driver 4, the first transmission member 2 is first sleeved on the drive shaft 41, and then the second transmission member 3 is sleeved on the drive shaft 41, so that the second transmission member 3 is closer to the end side of the drive shaft 41 than the first transmission member 2.

[0053] According to the above content, since the connecting member 1 is provided between the second transmission member 3 and the driving shaft 41, the second transmission member 3 will not be driven by the driving shaft 41 and becomes a driven gear. Correspondingly, the first transmission member 2 is a driving gear that can drive the transmission belt to rotate. Therefore, the first transmission member 2 and the second transmission member 3 are arranged at different positions along the axial direction of the driving shaft 41, so that it is not easy for the first transmission member 2 and the second transmission member 3 to interfere with each other.

[0054] In another embodiment of the present application, the connecting member 1 and the driving shaft 41 are integrally formed or separately provided.

[0055] That is to say, the connecting member 1 can be fixedly connected to the drive shaft 41, or it can be produced separately from the drive shaft 41 and then assembled. When the connecting member 1 and the drive shaft 41 are integrally formed, when the transmission assembly is used, it is not necessary to sleeve the connecting member 1 on the drive shaft 41; when the connecting member 1 and the drive shaft 41 are separately provided, if the driver 4 needs to be replaced, the connecting member 1 can be disassembled to replace the driver.

[0056] According to the above, the integral molding of the connecting member 1 and the driving shaft 41 helps to simplify the production process and save production costs. When the connecting member 1 and the driving shaft 41 are separately arranged, it is convenient to carry and use.

[0057] The embodiment of the present application further provides a transmission box 10, comprising the above-mentioned transmission assembly.

[0058] The transmission box 10 refers to a box body, which includes the above-mentioned transmission assembly. That is, the transmission box 10 may include a shell, in which the above-mentioned transmission assembly is installed. It should be noted that, since the transmission assembly needs to be connected to the driving shaft 41 of the driver 4, a hole structure can be opened on the shell according to actual needs, so that the transmission assembly can be connected to the driver 4 and the transmission belt and other structures.

[0059] According to the above content, the transmission box 10 includes a transmission assembly, so that the transmission box 10 can be connected to the driving shaft 41 of the driver 4 during use, so that one of the first transmission member 2 and the second transmission member 3 in the transmission assembly rotates with the driving shaft 41, and the other does not rotate with the driving shaft 41. In this way, when it is necessary to control the double-open curtain more flexibly, the first transmission member 2 in the transmission box 10 can be used to connect one curtain in the double-open curtain, and the second transmission member 3 can be used to connect the other curtain in the double-open curtain. When the driving shaft 41 of the driver 4 rotates, the first transmission member 2 drives the curtain connected to it to move, and the curtain connected to the second transmission member 3 does not move. The two curtains are one moving and the other static, which improves the control flexibility.

[0060] The present application also provides a transmission device, such as Figure 6 As shown, it includes a guide rail 5 and the above-mentioned transmission box 10, and a cavity for accommodating the transmission assembly is opened in the guide rail 5.

[0061] The shape of the cavity is not specifically limited in this embodiment, and the purpose is to open a space in the guide rail 5 for accommodating the transmission assembly, and the space is the cavity. In addition, in one embodiment, the guide rail 5 has a certain length, and a transmission assembly needs to be set at both ends, so the cavity is opened along the length direction of the guide rail 5 and runs through the length direction of the guide rail 5.

[0062] For example, when a double-open curtain needs to be controlled, a transmission box 10 is provided at both ends of the guide rail 5, and two transmission belts are provided between the two transmission boxes 10, each of which is connected to a curtain of the double-open curtain. At this time, the transmission belt is also located in the cavity and moves in the cavity to drive the curtain to move.

[0063] Through the above content, the transmission device not only includes a transmission box 10, but also includes a guide rail 5 with a cavity, so that when the double-opening curtain needs to be controlled, the transmission device can be directly used to control the double-opening curtain, which is convenient for improving the installation convenience of the curtain related structure and the control flexibility of the curtain.

[0064] In another embodiment of the present application, Figure 6As shown, the guide rail 5 includes a shell, and the cavity includes a first cavity 51 and a second cavity 52;

[0065] The first cavity 51 is used to accommodate the first transmission member 2, and the second cavity 52 is used to accommodate the second transmission member 3.

[0066] Or the first cavity 51 is used to accommodate the second transmission member 3 , and the second cavity 52 is used to accommodate the first transmission member 2 .

[0067] In one embodiment, the cavity is divided into a first cavity 51 and a second cavity 52, so that two conveyor belts can be accommodated in the cavity at the same time. Therefore, when the transmission device is used, a transmission box 10 is installed at both ends of the guide rail 5. Since each transmission box 10 includes a first transmission member 2 as a driving gear and a second transmission member 3 as a driven gear, when the first transmission member 2 is installed in the first cavity 51, the second transmission member 3 is installed in the first cavity 51 at the other end of the guide rail 5. Similarly, when the second transmission member 3 is installed in the second cavity 52, the first transmission member 2 is installed in the second cavity 52 at the other end of the guide rail 5.

[0068] According to the above content, the cavity includes a first cavity 51 and a second cavity 52, which facilitates the application of the transmission device in the field of double-open curtains to control the two curtains of the double-open curtains, improve the control flexibility, and meet the user's usage needs.

[0069] In another embodiment of the present application, Figure 7-8 As shown, the transmission device further includes a first transmission member 6, a second transmission member 7, a first connecting member 8 and a second connecting member 9;

[0070] The first transmission member 6 is disposed in the first cavity 51 and is used to connect with the first transmission member 2 and the second transmission member 3 at two ends of the first cavity 51;

[0071] The second transmission member 7 is disposed in the second cavity 52 and is used to connect with the second transmission member 3 and the first transmission member 2 at two ends of the second cavity 52;

[0072] The first connecting member 8 is disposed on the first transmission member 6 for connecting to a first target object, and the second connecting member 9 is disposed on the second transmission member 7 for connecting to a second target object.

[0073] In one embodiment, the first transmission member 6 and the second transmission member 7 are both used to drive other mechanisms to move under the action of the transmission component. Therefore, the first transmission member 6 and the second transmission member 7 only need to be connected to the transmission component and can be driven by the transmission component to move. For example, the first transmission member 2 and the second transmission member 7 are both transmission belts. After the transmission belts are sleeved in the two transmission components, the gear at one end of the transmission belt is the driving gear (that is, one end of the transmission belt is sleeved on the first transmission member 2), and the gear at the other end of the transmission belt is the driven gear (that is, the other end of the transmission belt is sleeved on the second transmission member 3). In this way, a mechanism that needs to move, such as a curtain, can be installed on the transmission belt. When the first transmission member 2 rotates, the first transmission member 6 or the second transmission member 7 connected thereto moves, thereby driving the curtain to move and realizing the control of the curtain.

[0074] Specifically, the first transmission member 6 is located in the first cavity 51 and is connected to the first connection member 8, and the second transmission member 7 is located in the second cavity 52 and is connected to the second connection member 9. The first connection member 8 and the second connection member 9 both play a connecting role, and are intended to be connected to the object that needs to be driven. For example, the first connection member 8 connects a curtain, and the second connection member 9 connects another curtain. It should be noted that the way the first connection member 8 and the second connection member 9 are connected to other structures is not limited in this embodiment, and can be hooked by its own hook-shaped structure, or clamped by its own clamping structure. Specifically, the first target object refers to the object that needs to be connected to the first connection member 8, and the second target object refers to the object that needs to be connected to the second connection member 9.

[0075] Take a double curtain as an example, one of the curtains is connected to the first connecting member 8, and the other curtain is connected to the second connecting member 9, and the two curtains are respectively the first target object and the second target object. Then the first connecting member 8 moves with the first transmission member 6, and the second connecting member 9 moves with the second transmission member 7. When one of the curtains needs to be moved, the first transmission member 6 or the second transmission member 7 can be controlled to move.

[0076] Through the above content, the transmission device includes a first transmission member 6, a second transmission member 7, a first connecting member 8 and a second connecting member 9, which is convenient for connecting the first target object and the second target object, and separately controlling the first target object and the second target object, thereby improving the control flexibility of the first target object and the second target object.

[0077] An embodiment of the present application also provides a driving device, including a driver 4 and the above-mentioned transmission assembly; the transmission assembly is arranged on the driving shaft 41; when the driver 4 drives the first transmission member 2 and the connecting member 1 in the transmission assembly to rotate, the connecting member 1 does not transmit driving force to the second transmission member 3, and the second transmission member 3 does not rotate due to the rotation of the driving shaft 41.

[0078] Specifically, the driver 4 cooperates with the transmission assembly to form a driving device. When one of the curtain fabrics needs to be driven, the driving device can be directly used to drive one of the curtain fabrics, and another driving device can be used to drive the other curtain fabric. The driver 4 refers to a device that can generate a rotational output, such as a motor or a rotary cylinder.

[0079] Through the above content, the driver 4 and the transmission assembly are matched, so that when improving the structure of the existing double-opening curtain, the driver 4 can be directly replaced by a driving device, which is convenient and quick, and improves the control flexibility of the double-opening curtain.

[0080] In another embodiment of the present application, the cross-sectional shape of the driving shaft 41 is a polygon.

[0081] Among them, polygon refers to a shape with multiple sides, such as a triangle or a pentagon. It should be noted that the polygon referred to in this embodiment is intended to utilize the shape of the drive shaft 41 to produce a snap-fit ​​relationship with the first transmission member 2 and the connecting member 1 in the transmission assembly. That is to say, after the first transmission member 2 and the connecting member 1 are sleeved on the drive shaft 41, the drive shaft 41 and the first transmission member 2 and the connecting member 1 cannot rotate relative to each other due to the cross-sectional shape, and become a whole, so that the drive shaft 41 can drive the first transmission member 2 and the connecting member 1 to rotate. Specifically, for example, the cross-sectional shape of the drive shaft 41 can also be an 8-shaped or a 0-shaped shape, etc., and it can be non-circular.

[0082] Through the above content, by designing the cross-sectional shape of the drive shaft 41, it is convenient to establish a snap-fit ​​relationship between the drive shaft 41 and the first transmission member 2 and the connecting member 1, without the need for additional connection design between the drive shaft 41 and the first transmission member 2 and the connecting member 1, thereby simplifying the number of parts and assembly difficulty of the drive body.

[0083] The present application also provides a transmission system. Figure 7 As shown, it includes a driver 4 and the above-mentioned transmission device, the driver 4 is provided with at least two, the two drivers 4 include a first driver and a second driver, and a transmission box 10 is installed on the two drivers 4, and the two transmission boxes 10 are respectively a first transmission box connected to the first driver and a second transmission box connected to the second driver;

[0084] The first driver and the first transmission box are arranged at one end of the guide rail 5, and the second driver and the second transmission box are arranged at the other end of the guide rail 5; the first transmission member 6 is reciprocatably arranged between the first transmission member 2 of the first transmission box and the second transmission member 3 of the second transmission box, and the second transmission member 7 is reciprocatably arranged between the second transmission member 3 of the first transmission box and the first transmission member 2 of the second transmission box.

[0085] The driver 4 includes a first driver and a second driver, and the transmission box 10 includes a first transmission box and a second transmission box, and the first driver is connected to the first transmission box, and the second driver is connected to the second transmission box, so that both ends of the guide rail 5 have a driver 4 and a transmission box 10. It should be noted that in order to ensure that there is no interference when the first driver and the second driver are started. In one embodiment, the first transmission member 2 in the first transmission box is located above the second transmission member 3, and the first transmission member 2 in the second transmission box is located below the second transmission member 3. In other words, the first transmission member 2 in the first transmission box and the second transmission box cannot be connected to the first transmission member 6 or the second transmission member 7 at the same time. Similarly, the second transmission member 3 in the first transmission box and the second transmission box cannot be connected to the first transmission member 6 or the second transmission member 7 at the same time. That is, the two first transmission members 2 in the two transmission boxes 10 need to be respectively arranged in the two cavities of the guide rail 5, and the two second transmission members 3 also need to be respectively arranged in the two cavities of the guide rail 5.

[0086] Then, a first transmission member 6 and a second transmission member 7 are arranged between the first transmission box and the second transmission box, wherein the first transmission member 6 is located in the first cavity 51 of the guide rail 5, and the second transmission member 7 is located in the second cavity 52 of the guide rail 5. Thus, when the first driver is turned on, the first transmission member 6 moves, which can drive the curtain connected to the first transmission member 6 to move, and when the second driver is turned on, the second transmission member 7 moves, which can drive the curtain connected to the second transmission member 7 to move. The two curtains can be controlled separately, which improves the control flexibility.

[0087] In another embodiment of the present application, the first transmission member 6 and the second transmission member 7 are belts, the first transmission member 2 and the second transmission member 3 are pulleys, and the connecting member 1 is a sleeve;

[0088] The first target object and the second target object are curtain fabrics.

[0089] The pulley can be used to place the belt and drive the belt to move when the pulley rotates. Figure 5 As shown, it is convenient to be sleeved on the driving shaft 41, and the whole structure is a hollow cylindrical structure.

[0090] Through the above content, the first target object and the second target object are both curtain fabrics, so that the two curtain fabrics of the double-open curtain can be controlled to move independently, and because there are no special requirements for the driver 4, it is only necessary to set a transmission component on the existing driver 4 and install a guide rail 5 to complete the flexible control of the double-open curtain, thereby reducing the cost required for flexible control of the double-open curtain.

[0091] An embodiment of the present application also provides a curtain assembly, comprising the above-mentioned transmission system.

[0092] Through the above content, a transmission system is provided in the curtain assembly, which facilitates the individual control of the two curtains and improves the control flexibility of the curtain.

[0093] In the above embodiments of the present application, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, please refer to the relevant description of other embodiments.

[0094] The above is only a preferred implementation of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
