Description

[Technical Field]

[0001] The present invention relates to the technical field of curtains, and more particularly to a motorized no-punch mounting device for curtains and its top frame mounting assembly. [Background technology]

[0002] Curtains are widely used in homes, offices, and other places, and are mainly used to adjust the lighting inside a room. Currently, roller blinds, blinds, honeycomb shades, etc. are widely used. When installing curtains, they generally need to be fixed to a window frame using mounting brackets and screws. When installing curtains using screws, screw holes are left in the window frame, and when reinstalling or replacing curtains, holes must be drilled again, and they cannot be installed on the spot. This inevitably leaves multiple screw holes in the wall of the window frame, which not only damages the wall but also affects the aesthetics. In addition, drilling holes for installation generates dust, making cleaning inconvenient and time-consuming to install. Many curtains that can be installed without drilling are available on the market, but conventional no-drilling assemblies require manual operation during use. Basically, the window frame is supported by an elastic assembly, and then a tightening and restricting member is manually adjusted to complete the installation. Most curtain installation positions have a certain installation height, so manual installation and adjustment require a person to climb up to operate it. This manual operation is time-consuming, making installation cumbersome and reducing installation efficiency. Summary of the Invention [Problem to be solved by the invention]

[0024] As shown in Figures 1 to 7, the present invention provides an electric mounting device that does not require drilling holes in curtains, and includes a housing 1, a housing cavity 1.3 defined within the housing 1, an electric drive module 2 that supplies power, a clamping module, and a telescopic adjustment module disposed in that order within the housing cavity 1. The electric drive module 2 is fixed within the housing cavity 1.3, one end of the clamping module is connected to the power output end of the electric drive module 2, and the other end of the clamping module is connected to the telescopic adjustment module, and the end of the telescopic adjustment module remote from the clamping module is exposed outside the housing 1 and is used to abut against the mounting surface for temporary positioning, the telescopic adjustment module has an adjustable telescopic length, and the electric drive module 2 drives the clamping module to tighten or loosen it, and in the tightened state, the length of the telescopic adjustment module protruding from the housing 1 is fixed, and in the loosened state, the length of the telescopic adjustment module protruding from the housing 1 can be adjusted as desired within the range of the telescopic adjustment module's adjustable length.

[0025] In the present invention, the telescopic adjustable module has an adjustable telescopic length, allowing temporary installation, after which the electric drive module 2 drives the tightening module to hold and secure the telescopic adjustable module, completing the permanent installation. When removing the curtain, the electric drive module 2 drives the tightening module to retract, allowing it to elastically return to its original position to release its hold on the telescopic adjustable module, allowing the telescopic adjustable module to freely adjust its length, allowing the curtain to be removed. During this process, tightening and loosening are completed electrically through the electric drive module 2, eliminating the need for manual operation, making it easy to use and reducing effort.

[0026] Referring to FIG. 2, the housing 1 comprises a main body 1.1 and an end cover 1.2 detachably connected to the main body 1.1. The detachable end cover 1.2 is convenient for assembly and replacement and is suitable for different types of curtain top frames. A limiting member 13 is fixed to one end of the main body 1.1, and the end cover 1.2 is detachably connected to the limiting member 13. The installation of the limiting member 13 provides a connecting function and also reduces damage to the main body 1.1. The electric drive module 2 is fixedly mounted in the receiving cavity 1.3 of the main body 1.1 at the end remote from the limiting member 13. The telescopic adjustment module is provided with a stopper 3.1 that fits into the limiting member 13 and prevents the telescopic adjustment module from falling off the housing 1 in the axial direction. The installation of the limiting member 13 on the one hand facilitates the detachable connection and replacement of the end cover 1.2, and on the other hand provides an axial limiting and stopping function to prevent the telescopic adjustment module from falling off the housing 1 in the axial direction.

[0027] 2, 3, and 4, the telescopic adjustment module includes a tension rod 3, a tension block 4, and a first spring 5, and the tightening module includes a screw rod 7, a first slider 8, a second slider 9, and a tightening assembly. The tension rod 3 passes through the tension block 4, the first spring 5, an end cap, a limiting member, the second slider 9, and the first slider 8 in this order from the outside to the inside. The tension block 4 is fixed to the end of the tension rod 3 with a screw and is used to abut against an installation surface. The screw rod 7 is connected to the power output end of the electric drive module 2 so as to be able to transmit power, the first slider 8 is threaded onto the screw rod 7, the clamping assembly is attached within the second slider 9 and is used to hold or release the tension rod 3, the stopper portion 3.1 is integrally formed with the tension rod 3, and in its natural state, the first spring 5 presses toward both ends, with one end of the first spring 5 abutting against the inner end surface of the tension block 4 and the other end abutting against the inner end surface of the end cap 1.2, and the stopper portion 3.1 abutting against the limiting member 13. In its natural state, the first spring 5 pushes the tension block 4 to slide out of the end cover 1.2 by a maximum distance, which is the maximum extension and retraction adjustment length of the electric mounting device that does not require drilling. When adjusting, the tensioning block 4 is pushed inward to compress the first spring 5 and temporarily install it, then the electric drive module 2 rotates the screw rod 7, which moves the first slider 8 along the axial direction of the screw rod 7 and pushes in the second slider 9, and the second slider 9 simultaneously moves the clamping assembly until it holds the tension rod 3 and completes the clamping installation. The telescopic length can be adjusted, so the installation range is relatively wide, suitable for various curtain top frames and suitable for installation on windows of various sizes, and electric installation can also be achieved, saving effort.

[0028] Referring to FIG. 3, the clamping assembly includes a first holding block 10, a second holding block 11, and an elastic member 12. The second slider 9 is provided with a first channel 9.1 for fitting the tension rod 3 therein. The second slider 9 is also provided with a second channel 9.2, which is perpendicular to the first channel 9.1 and for attaching the first holding block 10 and the second holding block 11. The first holding block 10 and the second holding block 11 are symmetrically arranged in the second channel 9.2. The tension rod 3 passes between the first holding block 10 and the second holding block 11, and the elastic member 12 is provided between the first holding block 10 and the second holding block 11. When the first holding block 10 and the second holding block 11 are subjected to opposing pressing forces, the first holding block 10 and the second holding block 11 move close to each other to hold the tension rod 3. When the external force is removed, the elastic member 12 pushes the first holding block 10 and the second holding block 11 in opposite directions, causing the tension rod 3 to be released. The tension rod 3 is tightened by being held close to and loosened by being released by the first holding block 10 and the second holding block 11 moving close to and away from each other, and the installation of this structure improves the tightening effect, makes the structure more stable in the tightened state, makes the installation stronger, and makes it less likely to fall off after a period of use. Referring to Figure 5, the elastic member 12 is a spring, and two springs are arranged in a set between the first holding block 10 and the second holding block 11. The springs are arranged symmetrically on both the upper and lower sides of the tension rod 3 so as to avoid the tension rod 3 and not hinder the axial movement of the tension rod 3. The first holding block 10 and the second holding block 11 are provided with spring grooves 10.1 and 11.1 for mounting the springs.

[0029] 2, 3, and 6, symmetrical extension arms 13.1 are formed on both sides of the limiting member 13, trapezoidal grooves 13.2 are recessed on both sides of the extension arms 13.1, and the first holding block 10 and the second holding block 11 are provided with trapezoidal blocks 10.2 and 11.2 that fit into the trapezoidal grooves 13.2. The trapezoidal groove 13.2 and the slopes of the trapezoidal blocks 10.2 and 11.2 cooperate to radially compress the first and second holding blocks 10 and 11. For example, when the second slider 9 is compressed and moved forward, the first and second holding blocks 10 and 11 are moved together, and the slopes of the trapezoidal blocks 10.2 and 11.2 on the first and second holding blocks 10 and 11 slide along the slopes of the trapezoidal groove 13.2, causing the first and second holding blocks 10 and 11 to approach each other under a radial compressive force, thereby holding the tension rod 3. When the spring between the holding block 10 and the second holding block 11 is compressed and the second slider 9 releases the axial pressure, the spring between the first holding block 10 and the second holding block 11 pushes the first holding block 10 and the second holding block 11 apart, and the trapezoidal blocks 10.2 and 11.2 on the first holding block 10 and the second holding block 11 return to the trapezoidal groove 13.2 along the slope, causing the first holding block 10 and the second holding block 11 to release the tension rod 3, and rapid tightening and loosening can be achieved by radial pressure and return, with a simple and compact structure.

[0030] 3, 5, and 7, the tension rod 3 is provided with a holding portion 3.2, and a number of locking teeth 3.3 are arranged at equal intervals on both sides of the holding portion 3.2. The first holding block 10 and the second holding block 11 are provided with U-shaped grooves 10.3 and 11.3 through which the tension rod 3 passes. The bottom surfaces of the U-shaped grooves 10.3 and 11.3 are provided with locking tooth surfaces 10.4 and 11.4 that engage with the locking teeth 3.3. In the tightened state, The first and second holding blocks 10 and 11 hold the tension rod 3, and the locking tooth surfaces 10.4 and 11.4 engage with the locking teeth 3.3 of the holding portion 3.2 to prevent axial movement of the tension rod 3. In the release state, the first and second holding blocks 10 and 11 disengage from the tension rod 3, allowing the tension rod 3 to move between the two opposing U-shaped grooves 10.3 and 11.3, thereby allowing the released tension rod 3 to move axially. The arrangement of the locking teeth 3.3 and locking tooth surfaces 10.4 and 11.4 facilitates quick and accurate engagement.

[0031] 2, 3, 4, 6, and 7, the telescopic adjustable module further includes a second spring 6, which fits the tension rod 3 and is located between the first slider 8 and the second slider 9. The elastic force of the first spring 5 is smaller than that of the second spring, which is long and slender with low elasticity, while the second spring 6 is thick and short with high elasticity. The first spring 5 elastically presses the tension rod 3 for temporary installation, and its low elastic force makes it easy to press and adjust the telescopic length. The second spring 6 acts as an elastic stroke compensation mechanism, preventing the curtain from loosening or falling after a long period of time has passed since installation. The second spring 6 compensates for the elastic displacement, preventing the curtain from falling after a certain period of time has passed since installation. For example, after the tension block 4 on the tension rod 3 abuts against the mounting surface and the temporary installation is completed, the electric drive module 2 drives the screw rod 7 to move the first slider 8 and push the second spring 6, and the second spring 6 pushes the second slider 9 until the first holding block 10 and the second holding block 11 on the second slider 9 hold the tension rod 3, at which point the first holding block 10, the second holding block 11 and the tension rod 3 tighten against each other, the tension rod 3 is tensioned against the mounting surface, the second slider 9 also stops moving forward, the first slider 8 continues to move forward and pushes the second spring 6 until it is tightened, and the electric drive module 2 stops operating. For example, if a single spring is used and the elastic force is too small, it is convenient to adjust the extension length of the tension rod 3 during temporary installation, but the elastic force is likely to be lost after a while after installation, the lifespan of the elastic force is short, and the problem of the curtain falling is likely to occur.If the elastic force is too large, it is more difficult to adjust the extension length of the tension rod 3, but the period of use after installation will be longer and the curtain will be less likely to fall.Therefore, by using an overlapping first spring 5 and second spring 6, not only can the extension length of the tension rod 3 be easily adjusted during temporary installation, but the problem of the curtain easily falling after a while after installation can also be prevented, the lifespan is longer, and it is safer.In addition, the first spring 5 and the second spring 6 are arranged separately, with the first spring 5 being located at the end of the tension rod 3 away from the tightening module, and the second spring 6 being located within the tightening module, between the first slider 8 and the second slider 9. This allows the driving stroke of the electric drive module 2 to be reduced, and since the compression range is small, the tightening time is shorter, the tightening and loosening speed is faster, and a smaller output electric drive module 2 can be selected, resulting in lower costs.

[0032] 2, 3, and 6, a first signal switch 14 is provided on the end of the first slider 8 close to the electric drive module 2, and a second signal switch 15 is provided on the end of the first slider 8 close to the second slider 9. The first signal switch 14 is used to detect the loosening stroke position when the first slider 8 is retracted, and the second signal switch 15 is used to detect the locking stroke position when the first slider 8 is advanced. When the first signal switch 14 and the second signal switch 15 detect the set stroke positions, they stop the operation of the electric drive module 2 and complete the loosening or tightening. The installation of the first signal switch 14 and the second signal switch 15 enables the electric drive module 2 to provide controllable loosening and locking strokes, preventing the second spring 6 from being over-compressed and damaging adjacent components, providing a controllable clamping force and extending the service life. It also provides the electric drive module 2 with an optimal drive stroke, i.e., the travel distance of the first slider 8 can be controlled, preventing the electric drive module 2 from over-driving the screw rod 7 and moving the first slider 8, thereby saving effort.

[0033] The electric drive module 2 is a motor equipped with a drive mechanism and a reducer, and the motor supplies power to rotate the screw rod 7, realizing stable, energy-saving, and electric operation.

[0034] As shown in Figure 8, the set frame mounting assembly comprises a top frame 16, and the above-mentioned no-drilling curtain electric mounting device is connected to one end of the top frame 16, the end face of the end cover 1.2 abuts against the end of the top frame 16, and a cover cap 17 is connected to the other end of the top frame 16. The cover cap 17 is not only a general cover cap, but also includes, for example, the side end of a motor device, a power supply device, and a transmission device, and when the motor device, power supply device, and transmission device are inserted into the top frame, they can shield the end of the top frame.

[0035] When assembling, the electric mounting device, which does not require drilling holes in the curtain, is inserted into the top frame 16, the other end of the top frame 16 is inserted into the cover cap 17, and the curtain body can be attached below the top frame 16. When installing, the tension block 4 is placed against the mounting wall, and the other end of the top frame 16 is placed against the opposite mounting wall, and the tension block 4 receives the elastic pressing force of the first spring 5, supporting the top frame 16 in the mounting position, completing the temporary installation. The motor is then driven to rotate the screw rod 7, causing the first slider 8 on the screw rod 7 to slide along the screw rod 7 in the direction of the second slider 9, and the first slider 8 presses against the second spring 6 and second slider 9, causing the first holding block 10 and second holding block 11 inside the second slider 9 to move simultaneously with the second slider 9. When the slider 8 is moving, it is pressed radially by the slope of the trapezoidal groove 13.2 on the limiting member 13. The trapezoidal groove 13.2 and the slope of the trapezoidal blocks 10.2 and 11.2 slide against each other, generating a radial pressing force. This causes the first retaining block 10 and the second retaining block 11 to approach each other and hold the tension rod 3. That is, the locking tooth surfaces 10.4 and 11.4 on the first retaining block 10 and the second retaining block 11 engage with the locking tooth 3.3 on the tension rod 3, stopping the advancement of the second slider 9. At this time, the first slider 8 continues to slide along the screw rod 7 toward the second slider 9. The first slider 8 compresses the second spring 6. When the second signal switch 15 on the first slider 8 detects the locking stroke position due to the advancement of the first slider 8, the motor stops operating, tightening the tension rod 3 so that it cannot move axially. This completes the installation. Even after the top frame 16 has been attached for a long period of time, the elastic force of the second spring 6 can push in the second slider 9, first holding block 10, second holding block 11, tension rod 3, and tension block 4 in order, keeping the tension block 4 in tight contact with the mounting wall at all times, making it less likely to fall off and allowing for stable attachment.When removing the screw rod 7, the motor is rotated in the reverse direction, and the motor rotates the screw rod 7 in the reverse direction, causing the first slider 8 on the screw rod 7 to move away from the second slider 9 along the screw rod 7. When the first signal switch 14 on the first slider 8 detects the loosening stroke position due to the retreat of the first slider 8, the motor stops operating, the second spring 6 is released, and the second slider 9 loses its axial pressing force. At this time, the spring between the first holding block 10 and the second holding block 11 pushes the first holding block 10 and the second holding block 11 away from each other, and the second The trapezoidal blocks 10.2 and 11.2 on the first retaining block 10 and the second retaining block 11 are returned into the trapezoidal groove 13.2 of the limiting member 13, and the first retaining block 10 and the second retaining block 11 are disengaged from the tension rod 3, loosening the tension rod 3. By pushing in the tensioning block 4, the tension rod 3 can be pushed and moved axially, allowing the top frame 16 to be removed from its mounting position. During the tightening and loosening process of the tension rod 3, the motor electrically drives the reciprocating movement of the first slider 8, and the spring returns to loosen it, eliminating the need for manual operation, making it easy to use and reducing labor. Furthermore, the second signal switch 15 on the first slider 8 can sense the locking stroke position as the first slider 8 advances, allowing the motor to provide a controllable tightening force without over-compressing the second spring 6. Furthermore, the end cover 1.2 is removably connected to the restricting member 13 on the housing 1, making it easy to replace the end cover 1.2. It can be adapted to different sizes of top frames 16, making it suitable for windows of different widths, and has a wide range of installation applications. The telescopic length can be adjusted to further expand the range of applications. Electric installation is possible without drilling, making it easy to use and labor-saving.
