Description

TECHNICAL FIELD

[0001] The present application relates to the field of electric curtain motors, in particular to an electric curtain motor and a track. BACKGROUND

[0002] The electric curtain is also called automatic curtain. The operation of the electric curtain does not need to walk to the window to manually pull the curtain. It only needs to be operated through a handheld remote control device. The device can be a smart phone or a device similar to a television remote control.

[0003] The existing electric curtain generally sets a curtain motor orthogonal to the curtain track at one end of the curtain track. The curtain motor drives the sliding block on the curtain track to slide to realize the automatic opening and closing of the curtain. The curtain motor is generally powered by a wire or a battery connected to the motor housing.

[0004] The existing battery-powered curtain motor generally connects the battery to the end of the motor housing away from the output end. Some curtain motors have a high installation position of the battery. When the battery of the curtain motor needs to be replaced, tools are needed to climb to the height of the curtain track. The battery is removed from the housing of the curtain motor from the mounting slot of the curtain track. Since most of the existing curtain motors are installed at one end of the track, the gravity of the folded curtain and the curtain motor acts on one end of the curtain track in the open state of the curtain. Long-term use can cause the curtain track to tilt towards the side where the curtain motor is installed. Therefore, the existing curtain motor is not easy to replace the battery connected to the housing during use. SUMMARY

[0005] Therefore, the purpose of the present application is to provide an electric curtain motor and a track to solve the technical problem that the existing curtain motor is not easy to replace the battery connected to the housing during use.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical scheme: an electric curtain motor, comprising a motor body, an output end of the motor body is connected with a reducer, both sides of the reducer are connected with a first clutch, an input end rotating shaft of the first clutch is connected with a transmission disc through a transmission belt, both ends of the transmission disc are fixedly connected with a transmission shaft, the transmission shaft is rotatably connected below an output shaft of the motor body, both sides of the motor body are provided with a second clutch, a transmission belt is connected between an input shaft of the second clutch and the transmission disc, an output shaft of the second clutch is fixedly connected with a fixed rod, one end of the fixed rod is connected with a battery box for accommodating a battery.

[0008] The fixed rod is internally slidably connected with a sliding rod, one end of the sliding rod is fixedly connected with the battery box, and a pulling spring is connected between the other end of the sliding rod and the inner wall of the fixed rod.

[0009] By adopting the technical scheme, the sliding rod slidably connected in the fixed rod can be extended from the fixed rod when the fixed rod rotates downward by 90 degrees, and the height of the battery box is effectively increased.

[0010] The top surface of the battery box is provided with an opening with a size greater than that of the battery.

[0011] By adopting the technical scheme, the battery can be conveniently accessed from the opening arranged at the top end of the battery box.

[0012] The motor body is fixedly connected with a fixed sheet at one end away from the output shaft, both ends of the fixed sheet are fixedly connected with compression springs, and the motor body is rotatably provided with a support block above the compression springs for supporting the fixed rod.

[0013] By adopting the technical scheme, the fixed rod is supported by the support block rotatably arranged above the fixed sheet, and the fixed rod is prevented from rotating downward in the retracted state.

[0014] An electric curtain track comprises a track, a motor body and a reducer are fixedly installed in the middle of the track, a driving shaft is rotatably arranged in each end portion of the track, a driven shaft is rotatably connected to the outer wall of the other end portion, the driving shaft extends out of the track and is connected with the driven shaft and a sliding block chain, two slide grooves parallel to the sliding block chain are arranged on both sides of the track, a plurality of upper sliding blocks are slidably connected in the upper slide groove, a plurality of lower sliding blocks are slidably connected in the lower slide groove, two upper sliding blocks and two lower sliding blocks close to each other are fixedly connected with the sliding block chain, and the remaining upper sliding blocks and lower sliding blocks are slidably connected with the sliding block chain at the same time, and the upper sliding blocks and the lower sliding blocks are connected by fixed-length ropes.

[0015] By adopting the technical scheme, the curtain motor is arranged at the middle part of the curtain rail, the reducer connected with the output end of the curtain motor cooperates with the transmission belt to drive the slider chain outside the curtain rail to move, the weight of the curtain motor and the transmission assembly can be effectively dispersed when the curtain is opened and closed, and the deflection of the curtain rail caused by long-time use of the curtain motor can be effectively avoided.

[0016] The upper slider and the lower slider are both provided with hooks for hanging the curtain, and the heights of the hooks are consistent.

[0017] By adopting the technical scheme, the heights of the hooks of the upper slider and the lower slider are consistent, so that the bottom of the curtain can keep the same clearance from the ground after the curtain is hung on the upper slider and the lower slider, and the situation that one piece of the curtain is scratched by the ground can be avoided.

[0024] 2. This invention places the curtain motor in the middle of the curtain track and uses a gearbox connected to the output end of the curtain motor in conjunction with a transmission belt to drive the slider chain on the outside of the curtain track to move, thereby realizing the electric opening and closing of the curtain. Since the curtain motor is located in the middle of the curtain track, the weight of the curtain motor and transmission components can be effectively distributed when the curtain is opened and closed, thereby effectively avoiding the deflection phenomenon that occurs in the curtain motor track after long-term use.

[0025] 3. The present invention rotatably sets support blocks on both sides of the curtain motor away from the output end, and sets a spring structure below the support blocks. When the fixed rod is rotated and put into the curtain track, the support blocks restrict the rotation of the fixed rod when the fixed rod and the curtain motor are kept horizontal.

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0038] The embodiments of the present invention will now be described.

[0039] An electric curtain motor, such as Figures 1-10 As shown, the device includes a motor body 1, with a reducer 2 connected to the output end of the motor body 1. First clutches 3 are connected to both sides of the reducer 2. The input shaft of the first clutches 3 is connected to a transmission disc 5 via a transmission belt. The transmission disc 5 is fixedly connected to both ends of a transmission shaft 4, which is rotatably connected below the output shaft of the motor body 1. Second clutches 6 are provided on both sides of the motor body 1. Specifically, both the first clutches 3 and the second clutches 6 are electromagnetic clutches. A transmission belt connects the input shaft of the second clutches 6 to the transmission disc 5. A fixing rod 7 is fixedly connected to the output shaft of the second clutches 6. One end of each fixing rod 7 is connected to a battery box 9 for accommodating a battery 10. The top surface of the battery box 9 has an opening larger than the size of the battery 10. The opening of the battery box 9 is located on the top surface so that the battery 10 inside can be easily accessed through the opening at the top of the battery box 9 without falling out. Specifically, the wires connected to the battery 10 inside the battery box 9 extend into the interior of the sliding rod 8, and after bending at the end of the sliding rod 8 away from the battery box 9, they fit against the inner wall of the fixed rod 7. The length of the wires inside the fixed rod 7 is longer than the fixed rod 7, and then they pass out from the end of the fixed rod 7 near the second clutch 6 and connect to the power supply on the motor body 1. The power supply is split into various lines to supply power to the motor body 1 and each clutch.

[0040] Please see Figures 5-8The fixed rod 7 is internally slidably connected with a sliding rod 8, one end of the sliding rod 8 is fixedly connected with the battery box 9, and the other end is connected with the inner wall of the fixed rod 7 through a pulling spring. Specifically, the pulling spring generates deformation and accumulates elastic potential energy in the extension process of the sliding rod 8. The sliding rod 8 slidably connected inside the fixed rod 7 can extend from the inside of the fixed rod 7 in the state that the fixed rod 7 is rotated downward by 90 degrees, thereby effectively increasing the height of the battery box 9 descending, so that the battery box 9 can be lowered to the height at which the user can conveniently replace the battery 10, and the user does not need to climb to the height of the motor body 1 to replace the battery 10.

[0041] Please refer to Figures 6-10 The motor body 1 is fixedly connected with a fixed sheet 11 away from the output shaft, both ends of the fixed sheet 11 are fixedly connected with a compression spring 12, and the motor body 1 is rotatably provided with a support block 13 above the compression spring 12 for supporting the fixed rod 7. The fixed rod 7 is supported by the support block 13 rotatably arranged above the fixed sheet 11, which avoids downward rotation of the fixed rod 7 in the retracted state. Since the support block 13 is not blocked when it is rotated upward, the upward rotation of the fixed rod 7 can lift the support block 13. When the support block 13 is reset, the fixed rod 7 is rotated downward to a state that is horizontal with the motor body 1, and can be limited by the support block 13.

[0042] Example one

[0043] A motorized curtain track, such as Figures 1-10As shown, including track 14, the middle of track 14 is fixedly installed with motor body 1 and reducer 2, specifically, motor body 1 and reducer 2 are arranged at the middle of track 14, achieving the effect of gravity balance of track 14 in the state of curtain opening, avoiding the situation of track deflection due to the fixed connection of motor on one side of track 14, the end of track 14 is rotatably connected with driving shaft 15, and the other end of the outer wall is rotatably connected with driven shaft, driving shaft 15 extends out of track 14 and is connected with sliding block chain 16, specifically, driving shaft 15 in track 14 is connected with the output shaft of first clutch 3 through transmission belt, in the condition of sufficient battery 10 power, two groups of second clutch 6 are in the disconnected state, and when the first clutch 3 is controlled to be attracted, the torque of reducer 2 can be transmitted to the corresponding driving shaft 15, thereby realizing the opening and closing of the curtain on one side of track 14 and the screen on the other side, two parallel sliding grooves to sliding block chain 16 are arranged on both sides of track 14, a plurality of upper sliding blocks 17 are slidably connected in the upper sliding groove, and a plurality of lower sliding blocks 18 are slidably connected in the lower sliding groove, two upper sliding blocks 17 and lower sliding blocks 18 close to each other are fixedly connected with sliding block chain 16, and the remaining upper sliding blocks 17 and lower sliding blocks 18 are simultaneously slidably connected with sliding block chain 16, a plurality of upper sliding blocks 17 and a plurality of lower sliding blocks 18 are connected through fixed length ropes, specifically, sliding block chain 16 on both sides of track 14 is used for connecting curtain and screen, when sliding block chain 16 moves, two upper sliding blocks 17 and lower sliding blocks 18 close to each other move towards or away from each other, sequentially pushing or pulling each upper sliding block 17 and lower sliding block 18 to slide, thereby controlling the opening or closing of the curtain or screen.

[0044] Please refer to Figures 2-3 A hook for hanging the curtain is arranged on upper sliding block 17 and lower sliding block 18, and the height of the hook is consistent, specifically, hook structure is arranged on the bottom end of upper sliding block 17 and extends upward, and hook structure is arranged on the top end of lower sliding block 18 and extends downward, the hook structure on the bottom end of upper sliding block 17 and the hook structure on the top end of lower sliding block 18 are between two parallel sliding block chains 16 and are at the same height, the consistent height of the hooks of upper sliding block 17 and lower sliding block 18 makes the bottom of the curtain keep the same clearance from the ground after the curtain is hung on upper sliding block 17 and lower sliding block 18, avoiding the situation of scratching the ground with one piece of curtain.

[0045] Please refer to Figures 1-3 The top end of track 14 on both sides is fixedly connected with mounting ear 19, specifically, four pairs of mounting ears 19 are arranged along the length direction of track 14, two pairs of mounting ears 19 are arranged at the two ends of track 14 and the positions where motor body 1 is arranged on track 14, a plurality of mounting ears 19 are arranged along the length direction of track 14, and track 14 is installed in the curtain groove of the building through the expansion bolt hole formed by the plurality of mounting ears 19 along the length direction.

[0046] Example 2

[0047] A type of motorized curtain track, such as Figures 1-10 As shown, based on Embodiment 1, the difference is that L-shaped side baffles 20 are connected to both sides of the top of the track 14. The side baffles 20 can effectively cover the slider chains 16 on both sides of the track 14, improving the aesthetics of the curtain motor track. A plug ear 21 is fixedly connected to the top of the side baffle 20 at the position corresponding to the mounting ear 19. The plug ear 21 can engage with the mounting ear 19. After the track 14 is installed, the side baffle 20 is snapped onto both sides of the track 14 and then slid along its length, so that the plug ear 21 is inserted into the base of the mounting ear 19, achieving convenient installation of the side baffle 20. Specifically... The side panel 20 can be locked onto the edge of the track 14. When the side panel 20 is installed on the track 14, first, the insert ear 21 is offset from the mounting ear 19. After the side panel 20 is pressed against the track 14, the side panel 20 is slid along the length of the track 14 so that the insert ear 21 is inserted into the back of the mounting ear 19. This allows for easy sliding installation of the side panel 20. The same principle applies when removing the side panel 20. First, the side panel 20 is slid along the length of the track 14, and then the side panel 20 is removed along the width of the track 14. This allows for easy installation and removal of the side panel 20 within the narrow curtain track groove.

[0048] The working principle of this invention is as follows: When the battery 10's charge drops to a certain value, the two sets of first clutches 3 are disengaged, while the two sets of second clutches 6 are engaged. The torque generated by the forward operation of the motor body 1 is transmitted to the rotating shaft of the fixed rod 7 through the reducer 2 and the transmission shaft 4, causing the fixed rod 7 to rotate downward. The front end of the fixed rod 7 presses down the support block 13, and the compression spring 12 at the bottom of the support block 13 is compressed until the support block 13 can no longer contact the bottom surface of the fixed rod 7. At this point, the support block 13 can no longer restrict the downward rotation of the fixed rod 7, and the fixed rod 7 can rotate downward smoothly. The compression spring 12 will reset after the fixed rod 7 disengages from the support block 13. The sliding rod 8 inside the fixed rod 7 slides out from inside the fixed rod 7 under its own weight and the weight of the battery 10. During the sliding process, the tension spring inside the fixed rod 7 stretches and accumulates elastic potential energy. After the fixed rod 7 rotates ninety degrees and the sliding rod 8 moves from inside the fixed rod 7... The fixed rod 7 slides out, allowing the battery box 9 to be positioned at a lower height, thus facilitating the replacement of the battery 10. After the battery 10 is replaced, the motor body 1 is energized and outputs torque in the reverse direction. The two sets of first clutches 3 are disengaged, while the two sets of second clutches 6 are engaged. The fixed rod 7 rotates upward, and the front end of the fixed rod 7 lifts the support block 13 upward until the fixed rod 7 and the support block 13 disengage. After the support block 13 rotates back to its original position, the two sets of second clutches 6 disengage. The fixed rod 7 rotates downward under its own weight and rests on the support block 13. At this time, the fixed rod 7 is in a horizontal state. During the upward rotation of the fixed rod 7, the sliding rod 8 will gradually slide into the fixed rod 7 due to the elastic force of the tension spring inside the fixed rod 7, preventing the weight of the battery box 9 and the battery 10 from applying torque on the long lever arm, thereby enabling the support block 13 to stably support the fixed rod 7.
