[0002] Electric curtains are gradually replacing manually pulled curtains. Before installing electric curtains, the length of the curtain rails needs to be determined according to the size of the window. At present, some manufacturers have launched customized electric curtains, which can customize curtain rails of different lengths for users. Usually, multiple sections of rails are assembled. After determining the length of the window, curtain rails of corresponding lengths are assembled on site, and then workers install the assembled curtain rails on the ceiling.

It can be understood that the first curtain rail assembly 1000 is provided with curtain cloth, and the second curtain rail assembly 2000 is provided with curtain cloth to form a double-opening curtain.

[0029] The other structures and operations of the curtains are already recorded in the relevant technologies for ordinary technicians in this field and will not be described in detail here. The structure of the curtain guide rail will be introduced below.

[0030] The present invention relates to a curtain rail, which includes a first curtain rail assembly 1000, a second curtain rail assembly 2000 and a docking transmission box assembly 3000. One end of the first curtain rail assembly 1000 is spliced ​​and installed with the second curtain rail assembly 2000 through the docking transmission box assembly 3000 to achieve synchronous operation of the first curtain rail assembly 1000 and the second curtain rail assembly 2000.

The first end of the first guide rail 1100 is provided with a transmission guide wheel. The docking transmission box assembly 3000 includes a first transmission box 3100 and a first transmission wheel 3101. The first transmission wheel 3101 is arranged in the first transmission box 3100. The first transmission wheel 3101 is connected to the first transmission box 3100 through a rolling bearing. The first transmission box 3100 is connected to the second end of the first guide rail 1100, and the first transmission wheel 3101 is connected to the first transmission belt 1101 for transmission.

[0032] It can be understood that in the first curtain rail assembly 1000, the two ends of the first transmission belt 1101 are respectively connected to the first transmission wheel 3101 and the transmission guide wheel. Further, the first transmission belt 1101 is configured as a synchronous belt, and accordingly, the first transmission wheel 3101 and the corresponding transmission guide wheel are respectively configured as pulleys.

[0033] In conjunction with the accompanying drawings, the first curtain rail assembly 1000 includes a first pulley 1102, the first pulley 1102 is used to install the curtain fabric, the first pulley 1102 is connected to the first transmission belt 1101, and the first pulley 1102 is slidably connected to the first guide rail 1100. It can be understood that, driven by the first transmission belt 1101, the first pulley 1102 can reciprocate along the first guide rail 1100.

[0034] The second curtain rail assembly 2000 includes a second guide rail 2100, a second transmission belt 2101 and a transmission guide wheel, and transmission guide wheels are respectively provided at both ends of the second guide rail 2100. It can be understood that the second curtain rail assembly 2000 includes a second pulley, the second pulley is used to install the curtain fabric, the second pulley is connected to the second transmission belt 2101, and the second pulley is slidably connected to the second guide rail 2100. It can be understood that, driven by the second transmission belt 2101, the second pulley can reciprocate along the second guide rail 2100.

[0035] The docking transmission box assembly 3000 includes a second transmission box 3200 and a second transmission wheel 3201, wherein the second transmission wheel 3201 is disposed in the second transmission box 3200, and the second transmission wheel 3201 is connected to the second transmission box 3200 through a rolling bearing, and the second transmission box 3200 is disposed on the side of the second guide rail 2100, and the second transmission wheel 3201 is transmission-connected to the second transmission belt 2101. In some examples, the second transmission belt 2101 is configured as a synchronous belt, and accordingly, the second transmission wheel 3201 and the corresponding two transmission guide wheels are respectively configured as pulleys.

[0036] A guide wheel 3202 is provided in the second transmission box 3200, and the guide wheel 3202 is connected to the transmission wheel of the second transmission belt 2101. Combined with the accompanying drawings, there are two guide wheels 3202, and the two guide wheels 3202 are respectively provided in the second transmission box 3200 near the entrance and exit of the second transmission belt 2101, and the guide wheels 3202 play the role of redirecting and tensioning the second transmission belt 2101.

[0037] Furthermore, the second transmission box 3200 is designed to be movable along the second guide rail 2100, so that the position of the second transmission box 3200 can be adjusted according to the width of the window, thereby adjusting the length of the overlapping portion when the first guide rail 1100 and the second guide rail 2100 are docked.

[0038] In some examples, the second guide rail 2100 is provided with a guide connection structure, the second transmission box 3200 is connected to the guide connection structure, and the guide connection structure is arranged along the axial direction of the second guide rail 2100. On the one hand, the second transmission box 3200 can be moved along the guide connection structure, and on the other hand, the second transmission box 3200 can be connected to the second guide rail 2100. Specifically, the guide connection structure is arranged on the upper side of the second guide rail 2100, and the upper part of the second transmission box 3200 is installed with the guide connection structure.

[0039] When the first curtain rail assembly 1000 and the second curtain rail assembly 2000 are installed, the second transmission wheel 3201 is connected to the first transmission wheel 3101, and the first transmission box 3100 and the second transmission box 3200 are stacked. Specifically, the second transmission box 3200 is located above the first transmission box 3100. The second transmission wheel 3201 is designed to be coaxial with the first transmission wheel 3101. It can be understood that the second transmission wheel 3201 and the first transmission wheel 3101 are connected to each other through shaft transmission.

[0040] Specifically, the curtain rail includes a transmission connection shaft 4000, which passes through the second transmission wheel 3201, and the transmission connection shaft 4000 is transmission-connected with the second transmission wheel 3201. When the first curtain rail assembly 1000 and the second curtain rail assembly 2000 are installed, the first transmission wheel 3101 is located at the lower side of the second transmission wheel 3201, and the transmission connection shaft 4000 is plugged with the first transmission wheel 3101, and the transmission connection shaft 4000 is transmission-connected with the first transmission wheel 3101. It can be understood that the transmission connection shaft 4000 serves as an axis structure connecting the first transmission wheel 3101 and the second transmission wheel 3201, and the first transmission wheel 3101 and the second transmission wheel 3201 are transmission-connected through the transmission connection shaft 4000.

[0041] The transmission connecting shaft 4000 is used in the docking transmission box assembly 3000 to realize the transmission of the first transmission wheel 3101 and the second transmission wheel 3201. The first transmission box 3100 and the second transmission box 3200 are designed to be stacked so that the first transmission belt 1101 and the second transmission belt 2101 are staggered up and down, which can reduce the size of the docking transmission box assembly 3000 and thus reduce the space occupied by the curtain rail.

[0042] Furthermore, the transmission connection shaft 4000 can be used to disconnect the transmission connection between the first transmission wheel 3101 and the second transmission wheel 3201, thereby disconnecting the transmission connection between the first transmission belt 1101 and the second transmission belt 2101, so that the first transmission belt 1101 and the second transmission belt 2101 can move separately and independently, thereby adjusting the position of the first pulley 1102 and the second pulley to achieve centering and double opening of the curtain fabric.

[0043] The transmission connection shaft 4000 is designed to be movable in the axial direction, so as to disconnect the transmission connection between the transmission connection shaft 4000 and the first transmission wheel 3101. Specifically, the transmission connection between the transmission connection shaft 4000 and the first transmission wheel 3101 can be disconnected by lifting the transmission connection shaft 4000 upward, thereby disconnecting the transmission connection between the first transmission wheel 3101 and the second transmission wheel 3201.

[0044] It is understandable that the inner wall of the through hole of the second transmission wheel 3201 is provided with a sliding groove, the transmission connection shaft 4000 is provided with a sliding portion, the sliding portion is protrudingly provided on the side of the transmission connection shaft 4000, and the sliding portion is slidably connected with the sliding groove. As an equivalent replacement, it can also be designed that the second transmission wheel 3201 is connected to a rotating shaft sleeve, the transmission connection shaft 4000 passes through the rotating shaft sleeve, and the sliding groove is provided on the inner wall of the rotating shaft sleeve.

[0045] In conjunction with the accompanying drawings, the sliding groove includes a first sliding groove 4101, and the first sliding groove 4101 is arranged along the axial direction of the through hole of the second transmission wheel 3201. When the transmission connection shaft 4000 is lifted upward, the sliding part moves along the first sliding groove 4101. The transmission connection shaft 4000 and the first transmission wheel 3101 are key-connected, specifically, the transmission connection shaft 4000 and the first transmission wheel 3101 are spline-connected.

[0046] When the transmission connecting shaft 4000 is key-connected with the first transmission wheel 3101 and the transmission connecting shaft 4000 is engaged with the second transmission wheel 3201 through the first sliding groove 4101 and the sliding part, the transmission connecting shaft 4000 can be respectively connected to the first transmission wheel 3101 and the second transmission wheel 3201. In this case, lifting the transmission connecting shaft 4000 can separate the key connection between the transmission connecting shaft 4000 and the first transmission wheel 3101, thereby disconnecting the transmission connection between the transmission connecting shaft 4000 and the first transmission wheel 3101.

[0047] There are multiple sliding grooves, and correspondingly, there are multiple first sliding grooves 4101, and there are multiple sliding parts, so that the torque between the transmission connection shaft 4000 and the second transmission wheel 3201 is balanced, and the transmission connection shaft 4000 can move smoothly along the first sliding groove 4101. In some examples, there are two sliding grooves, and correspondingly, there are two first sliding grooves 4101.

[0048] Furthermore, a reset elastic member is provided in the second transmission box 3200, and the reset elastic member is configured as a compression spring. The reset elastic member is arranged between the top wall in the second transmission box 3200 and the transmission connecting shaft 4000, and the reset elastic member is used to apply an elastic thrust along the axial direction of the transmission connecting shaft 4000 to the transmission connecting shaft 4000.

[0049] It is understandable that after the transmission connecting shaft 4000 is lifted, the reset elastic member is in a compressed state. In this case, if the lifting of the transmission connecting shaft 4000 is released, under the action of the reset elastic member, the transmission connecting shaft 4000 can be reset and moved to the position connected to the first transmission wheel 3101.

[0050] In some examples, when the first curtain rail assembly 1000 and the second curtain rail assembly 2000 are installed, the second transmission box 3200 is located on the upper side of the first transmission box 3100, and the bottom of the first transmission box 3100 is provided with an operation hole, which runs through the bottom of the first transmission box 3100 so that a tool can be inserted to lift the transmission connection shaft 4000, or so that the lower end of the transmission connection shaft 4000 can extend from the operation hole. In some examples, when the first curtain rail assembly 1000 and the second curtain rail assembly 2000 are installed, the first transmission box 3100 is located on the upper side of the second transmission box 3200, and the operation hole is provided at the bottom of the second transmission box 3200.

[0051] In conjunction with the drawings, the sliding groove includes a second sliding groove 4102, which is arranged along the circumference of the through hole of the second transmission wheel 3201, and one end of the second sliding groove 4102 is connected to the first sliding groove 4101. In conjunction with the drawings, the second sliding groove 4102 is designed as a section of a groove body arranged along the circumference of the through hole of the second transmission wheel 3201.

[0052] After the transmission connecting shaft 4000 is lifted up, the transmission connecting shaft 4000 is rotated to allow the sliding portion to enter the second slide groove 4102, thereby keeping the transmission connecting shaft 4000 in the lifted position and maintaining the state where the transmission connecting shaft 4000 is disconnected from the first transmission wheel 3101. It can be understood that, combined with the elastic force of the reset elastic member, the sliding portion can be pressed downward against the side wall of the second slide groove 4102, thereby playing a role in fixing the position of the transmission connecting shaft 4000.

[0053] Furthermore, the lower end of the transmission connection shaft 4000 is provided with a torsion force structure, and the transmission connection shaft 4000 can be easily rotated by connecting the torsion force structure with a tool. In conjunction with the accompanying drawings, the torsion force structure is set as a straight groove. Of course, it can also be designed as: the torsion force structure is set as one of a cross groove, a prism structure, a plum blossom groove, and a straight protrusion structure.

[0054] In conjunction with the accompanying drawings, the sliding groove includes a third sliding groove 4103, the third sliding groove 4103 is connected to the other end of the second sliding groove 4102, and the third sliding groove 4103 and the first sliding groove 4101 are located on the same side of the second sliding groove 4102. After the transmission connection shaft 4000 is lifted and rotated, the sliding part can be moved to the third sliding groove 4103. The third sliding groove 4103 is used to limit the sliding part and the elastic force of the reset elastic member to prevent the sliding part from moving to the first sliding groove 4101, which helps to maintain the state of disconnecting the transmission connection between the transmission connection shaft 4000 and the first transmission wheel 3101.

[0055] Regarding the arrangement of the resetting elastic member, in some examples, a blind hole is arranged at the upper end of the transmission connecting shaft 4000, and the resetting elastic member is arranged in the blind hole to prevent the position of the resetting elastic member from being offset. Of course, as an alternative, it can also be designed as follows: a convex structure is arranged at the upper end of the transmission connecting shaft 4000, and the resetting elastic member is sleeved on the convex structure.

[0056] In order to fix the length of the curtain rail after installation and the position of the second transmission box 3200, the curtain rail is designed to include a first limiting component 5100 and a second limiting component 5200, wherein the first limiting component 5100 is used to fix the position of the second guide rail 2100 relative to the first guide rail 1100, and the second limiting component 5200 is used to fix the position of the docking transmission box assembly 3000. It can be understood that the length of the overlapping portion of the first guide rail 1100 and the second guide rail 2100 is fixed by the first limiting component 5100 and the second limiting component 5200, thereby fixing the length of the curtain rail after installation.

[0057] In conjunction with the accompanying drawings, the first limiting component 5100 is connected to the first guide rail 1100. When the first curtain rail assembly 1000 and the second curtain rail assembly 2000 are installed, the first end of the second guide rail 2100 is connected to the first guide rail 1100, and the first limiting component 5100 is against the first end of the second guide rail 2100, thereby fixing the position of the second guide rail 2100 relative to the first guide rail 1100.

[0058] Specifically, the first position-limiting component 5100 includes a first position-limiting clamping portion 5101 and a second position-limiting clamping portion 5102, the first position-limiting clamping portion 5101 and the second position-limiting clamping portion 5102 are respectively clamped with the first guide rail 1100, the first position-limiting clamping portion 5101 and the second position-limiting clamping portion 5102 are locked by a threaded connector, and the threaded connector is set as a bolt. In conjunction with the accompanying drawings, the upper side and the lower side of the first guide rail 1100 are respectively provided with a clamping groove, the clamping groove extends along the length direction of the first guide rail 1100, the first position-limiting clamping portion 5101 is clamped with the clamping groove on the upper side of the first guide rail 1100, the second position-limiting clamping portion 5102 is clamped with the clamping groove on the lower side of the first guide rail 1100, and the threaded connector locks the first position-limiting clamping portion 5101 and the second position-limiting clamping portion 5102, so that the first position-limiting component 5100 is fixedly installed with the first guide rail 1100.

[0059] In conjunction with the accompanying drawings, the second limiting component 5200 is connected to the second guide rail 2100. When the first curtain rail assembly 1000 and the second curtain rail assembly 2000 are installed, the second limiting component 5200 abuts against the end of the docking transmission box assembly 3000. Specifically, one end of the docking transmission box assembly 3000 faces the first guide rail 1100 and the first transmission box 3100 is connected to the end of the first guide rail 1100. The second limiting component 5200 abuts against the other end of the docking transmission box assembly 3000. The second limiting component 5200 abuts against the first transmission box 3100 and the second transmission box 3200, thereby fixing the position of the docking transmission box assembly 3000 on the second guide rail 2100.

[0060] Specifically, the second limiting component 5200 includes a third limiting clamping part and a fourth limiting clamping part, which are respectively clamped with the second guide rail 2100, and the third limiting clamping part and the fourth limiting clamping part are locked by a threaded connector, which is a bolt.

[0061] It can be understood that the upper and lower sides of the second guide rail 2100 are respectively provided with card slots, which extend along the length direction of the second guide rail 2100, the third limit card connection portion is carded with the card slot on the upper side of the second guide rail 2100, and the fourth limit card connection portion is carded with the card slot on the lower side of the second guide rail 2100, and the threaded connection part locks the third limit card connection portion and the fourth limit card connection portion to fix the second limit component 5200 and the second guide rail 2100.

[0062] After the curtain rails are installed, in order to keep the first rail 1100 and the second rail 2100 in close contact and avoid separation, a reinforced connection is designed where the first rail 1100 and the second rail 2100 are overlapped and spliced ​​to prevent the sides of the first rail 1100 and the second rail 2100 from separating.
