Description

No-drill electric curtain installation device and its top beam installation components Technical Field

[0001] This invention relates to the field of curtain technology, and in particular to a curtain non-drilling electric installation device and its top beam installation assembly. Background Technology

[0002] Curtains are widely used in homes and offices, primarily for regulating indoor light. Common types include roller blinds, Venetian blinds, and honeycomb blinds. Generally, installation requires mounting brackets and screws to fix the curtains to the window frame. Since screw installation creates screw holes in the window frame, re-drilling is necessary when reinstalling or replacing the curtains, preventing re-installation in the original location. This inevitably leaves multiple screw holes in the wall around the window frame, damaging the wall and affecting aesthetics. Drilling also generates dust, making cleaning inconvenient and time-consuming. Although many no-drill curtains are now available, existing no-drill installation components still require manual operation. They typically use elastic supports on the window frame, requiring manual adjustment and locking to complete the installation. Since curtains are usually installed at a certain height, manual adjustment requires climbing up to operate, making manual operation time-consuming, laborious, cumbersome, and inefficient.

[0003] Summary of the Invention

[0004] In view of the current state of the prior art, the technical problem to be solved by the present invention is to provide a curtain installation device without drilling and its top beam installation component, which can electrically control the installation of curtains without drilling, with high installation efficiency and saving time and effort.

[0005] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: a curtain non-drilling electric installation device, including a housing, a receiving cavity provided inside the housing, an electric drive module for providing power, a locking module and a telescopic adjustment module are arranged sequentially in the receiving cavity, the electric drive module is fixed in the receiving cavity, one end of the locking module is connected to the power output end of the electric drive module, the other end of the locking module is connected to the telescopic adjustment module, the end of the telescopic adjustment module away from the locking module is exposed outside the housing for abutting the installation surface for pre-positioning, the telescopic adjustment module has a telescopic adjustment length, the electric drive module drives the locking module to lock or unlock the telescopic adjustment module, in the locked state, the length of the telescopic adjustment module extending out of the housing is fixed, in the unlocked state, the length of the telescopic adjustment module extending out of the housing can be arbitrarily adjusted within its telescopic adjustment length range.

[0006] Furthermore, the housing includes a body and an end cap detachably connected to the body. A limiting member is fixed at the end of the body, and the end cap is detachably connected to the limiting member. The electric drive module is fixed in the accommodating cavity of the body at one end away from the limiting member. The telescopic adjustment module is provided with a stop portion that cooperates with the limiting member to prevent the telescopic adjustment module from axially dislodging from the housing.

[0007] Furthermore, the telescopic adjustment module includes a top rod, a top block, and a first spring; the locking module includes a lead screw, a first slider, a second slider, and a locking assembly. The top rod passes through the top block, the first spring, the end cap, the limiting member, the second slider, and the first slider in sequence from the outside to the inside. The lead screw is connected to the power output end of the electric drive module. The first slider is connected to the lead screw via a threaded connection. The locking assembly is installed inside the second slider to hold or release the top rod. The stop part is integrally formed on the top rod. In its natural state, the first spring is pressed towards both ends. One end of the first spring abuts against the inner end face of the top block, and the other end abuts against the inner end face of the end cap. The stop part abuts against the limiting member.

[0008] Furthermore, the locking assembly includes a first clamping block, a second clamping block, and an elastic element. The second slider has a first channel for fitting a push rod, and the second slider also has a second channel perpendicular to the first channel for installing the first clamping block and the second clamping block. The first clamping block and the second clamping block are symmetrically arranged in the second channel. The push rod passes between the first clamping block and the second clamping block. The elastic element is located between the first clamping block and the second clamping block. When the first clamping block and the second clamping block are subjected to opposing compressive forces, the first clamping block and the second clamping block move towards each other and clamp the push rod. When the external force is removed, the elastic element pushes the first clamping block and the second clamping block in the opposite direction to disengage from the push rod.

[0009] Furthermore, the elastic element is a spring, and the springs are arranged in pairs between the first clamping block and the second clamping block. The springs are symmetrically located on the upper and lower sides of the top rod, and both the first clamping block and the second clamping block are provided with spring grooves for installing the springs.

[0010] Furthermore, the limiting member has symmetrical extension arms formed on both sides, and trapezoidal grooves are recessed on both sides of the extension arms. The first clamping block and the second clamping block are both provided with trapezoidal blocks that cooperate with the trapezoidal grooves.

[0011] Furthermore, the top rod is provided with a clamping section, and both sides of the clamping section are provided with several equally spaced locking teeth. The first clamping block and the second clamping block are provided with U-shaped grooves for the top rod to pass through. The bottom surface of the U-shaped groove is provided with a locking tooth surface that engages with the locking teeth. In the locked state, the first clamping block and the second clamping block clamp the top rod, and the locking tooth surface engages with the locking teeth of the clamping section. In the unlocked state, the first clamping block and the second clamping block disengage from the top rod, and the top rod can move between the two opposing U-shaped grooves.

[0012] Furthermore, the telescopic adjustment module also includes a second spring, which is sleeved on the top rod and located between the first slider and the second slider, and the elastic force of the first spring is less than that of the second spring.

[0013] Furthermore, a first signal switch is provided at one end of the first slider near the electric drive module, and a second signal switch is provided at one end of the first slider near the second slider. The first signal switch is used to sense the travel position of the first slider when it is retracted and unlocked, and the second signal switch is used to sense the travel position of the first slider when it is forward and locked.

[0014] Furthermore, the electric drive module is a motor.

[0015] A top beam mounting assembly includes a top beam, one end of which is connected to a curtain no-drill electric mounting device as described above, and the other end of which is connected to a cover.

[0016] Compared with the prior art, the advantages of the present invention are as follows: The present invention achieves pre-positioning installation by using a telescopic adjustment module with telescopic adjustment length, and then uses an electric drive module to drive a locking module to hold the telescopic adjustment module for fixation, thus completing the installation. During disassembly, the electric drive module drives the locking module to retract its compression and elastically reset to release the grip on the telescopic adjustment module, allowing the telescopic adjustment module to extend and retract its length, thereby realizing the disassembly of the curtain. In this process, the locking and unlocking are completed electrically by the electric drive module, without the need for manual operation, making it convenient to use and saving time and effort.

[0028] The present invention will be further described below with reference to specific embodiments.

[0029] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" are used only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0030] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0031] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0032] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0033] As shown in Figures 1-7, the present invention provides a curtain-mounting device without drilling, comprising a housing 1, wherein a receiving cavity 1.3 is provided inside the housing 1.3, and an electric drive module 2 for providing power, a locking module, and a telescopic adjustment module are sequentially arranged in the receiving cavity 1.3. The electric drive module 2 is fixedly disposed in the receiving cavity 1.3. One end of the locking module is connected to the power output end of the electric drive module 2, and the other end of the locking module is connected to the telescopic adjustment module. The end of the telescopic adjustment module away from the locking module is exposed outside the housing 1 for abutting against the mounting surface for pre-positioning. The telescopic adjustment module has a telescopic adjustment length. The electric drive module 2 drives the locking module to lock or unlock the telescopic adjustment module. In the locked state, the length of the telescopic adjustment module extending out of the housing is fixed. In the unlocked state, the length of the telescopic adjustment module extending out of the housing can be arbitrarily adjusted within its telescopic adjustment length range.

[0034] This invention utilizes a telescopic adjustment module to achieve pre-positioning installation, followed by a locking module driven by an electric drive module 2 to secure the telescopic adjustment module and complete the installation. During disassembly, the electric drive module 2 drives the locking module to retract its compression and elastically reset, releasing the tension on the telescopic adjustment module and allowing it to extend or retract to adjust its length, thus enabling the curtain to be removed. The locking and unlocking processes are electrically completed by the electric drive module 2, eliminating the need for manual operation, making it convenient, time-saving, and labor-saving.

[0035] Referring to Figure 2, the housing 1 includes a body 1.1 and an end cap 1.2 detachably connected to the body 1.1. The detachable end cap 1.2 facilitates assembly and replacement to adapt to different models of curtain top beams. A limiting member 13 is fixedly provided at the end of the body 1.1. The end cap 1.2 is detachably connected to the limiting member 13. The limiting member 13 serves as a medium for connection and also reduces damage to the body 1.1. The electric drive module 2 is fixedly located in the accommodating cavity 1.3 of the body 1.1 at the end away from the limiting member 13. The telescopic adjustment module is provided with a stop part 3.1 that cooperates with the limiting member 13 to prevent the telescopic adjustment module from axially dislodging from the housing 1. The limiting member 13 facilitates the detachable connection and replacement of the end cap 1.2 and also serves as an axial limiting stop to restrict the telescopic adjustment module from axially dislodging from the housing 1.

[0036] Referring to Figures 2, 3, and 4, the telescopic adjustment module includes a top rod 3, a top block 4, and a first spring 5. The locking module includes a lead screw 7, a first slider 8, a second slider 9, and a locking assembly. The top rod 3, from the outside to the inside, sequentially connects the top block 4, the first spring 5, the end cap 1.2, the limiting member 13, the second slider 9, and the first slider 8. The top block 4 is fixed to the end of the top rod 3 by screws to abut against the mounting surface. The lead screw 7 is connected to the power output end of the electric drive module 2. The first slider 8 is threadedly connected to the lead screw 7. The locking assembly is installed inside the second slider 9 to hold or release the top rod 3. The stop part 3.1 is integrally formed on the top rod 3. In its natural state, the first spring 5 is pressed towards both ends, and one end of the first spring 5 is connected to the inner end of the top block 4. One end abuts against the other end, and the other end abuts against the inner end face of the end cover 1.2. The stop part 3.1 abuts against the limiting part 13. In the natural state, the first spring 5 pushes the top block 4 to slide out of the end cover 1.2 to the maximum distance. This maximum distance is the maximum telescopic adjustment length of the non-drilling electric installation device. During adjustment, the first spring 5 can be pre-positioned by pushing the top block 4 inward to compress it. Then, the electric drive module 2 drives the lead screw 7 to rotate. The lead screw 7 drives the first slider 8 to move along the axis of the lead screw 7 to push the second slider 9. The second slider 9 drives the locking component to move simultaneously until the locking component hugs the top rod 3, completing the locking installation. Since the telescopic length can be adjusted, the installation adaptability is relatively wide. It can match various curtain top beams and windows of various sizes. It can also achieve electric installation, saving time and effort.

[0037] Referring to Figure 3, the locking assembly includes a first clamping block 10, a second clamping block 11, and an elastic element 12. The second slider 9 has a first channel 9.1 for engaging the push rod 3, and a second channel 9.2 perpendicular to the first channel 9.1 for mounting the first clamping block 10 and the second clamping block 11. The first clamping block 10 and the second clamping block 11 are symmetrically arranged within the second channel 9.2. The push rod 3 passes between the first clamping block 10 and the second clamping block 11. The elastic element 12 is located between the first clamping block 10 and the second clamping block 11. When the first clamping block 10 and the second clamping block 11 are subjected to opposing compressive forces, they move closer together to clamp the push rod 3. When the external force is removed, the elastic element 12 pushes the first clamping block 10 and the second clamping block 11 in the opposite direction to disengage from the top rod 3. The clamping and locking of the top rod 3 is achieved by the mutual approach and separation of the first clamping block 10 and the second clamping block 11. This structure makes the locking effect better, the structure more stable in the locked state, the installation more secure, and it is not easy to fall off due to long-term use. Referring to Figure 5, the elastic element 12 is a spring. The springs are arranged in pairs between the first clamping block 10 and the second clamping block 11. The springs are symmetrically located on the upper and lower sides of the top rod 3, which can avoid the top rod 3 and will not hinder the axial movement of the top rod 3. The first clamping block 10 and the second clamping block 11 are provided with spring grooves 10.1 and 11.1 for installing the springs.

[0038] Referring to Figures 2, 3, and 6, the limiting member 13 has symmetrical extension arms 13.1 formed on both sides. Trapezoidal grooves 13.2 are recessed on both sides of the extension arms 13.1. The first clamping block 10 and the second clamping block 11 are each provided with trapezoidal blocks 10.2 and 11.2 that mate with the trapezoidal grooves 13.2. The radial pushing of the first clamping block 10 and the second clamping block 11 is achieved through the engagement of the trapezoidal grooves 13.2 and the inclined surfaces of the trapezoidal blocks 10.2 and 11.2. For example, when the second slider 9 is pushed forward, it will cause the first clamping block 10 and the second clamping block 11 to move together. The inclined surfaces of the trapezoidal blocks 10.2 and 11.2 on the first clamping block 10 and the second clamping block 11... The first clamping block 10 and the second clamping block 11 slide along the inclined surface of the trapezoidal groove 13.2, causing them to be squeezed together by radial pressure, thus clamping the top rod 3. At this time, the spring between the first clamping block 10 and the second clamping block 11 is compressed. When the second slider 9 removes the axial push, the spring between the first clamping block 10 and the second clamping block 11 pushes the first clamping block 10 and the second clamping block 11 away from each other. The trapezoidal blocks 10.2 and 11.2 on the first clamping block 10 and the second clamping block 11 return to the trapezoidal groove 13.2 along the inclined surface. The first clamping block 10 and the second clamping block 11 disengage from the top rod 3. The radial compression and return achieve rapid locking and unlocking. The structure is simple and compact.

[0039] Referring to Figures 3, 5, and 7, the top rod 3 is provided with a clamping section 3.2. Both sides of the clamping section 3.2 are provided with several equally spaced locking teeth 3.3. The first clamping block 10 and the second clamping block 11 are each provided with U-shaped grooves 10.3 and 11.3 for the top rod 3 to pass through. 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 locked state, the first clamping block 10... The second clamping block 11 clamps the top rod 3. The toothed surfaces 10.4 and 11.4 engage with the toothed surfaces 3.3 of the clamping section 3.2, thereby locking the top rod 3 to move axially. In the unlocked state, the first clamping block 10 and the second clamping block 11 disengage from the top rod 3, and the top rod 3 can move between the two opposing U-shaped grooves 10.3 and 11.3, thereby releasing the axial movement of the top rod 3. The setting of the toothed surfaces 10.4 and 11.4 facilitates quick and accurate engagement.

[0040] Referring to Figures 2, 3, 4, 6, and 7, the telescopic adjustment module further includes a second spring 6. The second spring 6 is sleeved on the top rod 3 and located between the first slider 8 and the second slider 9. The elastic force of the first spring 5 is less than that of the second spring 6. The first spring 5 is slender and has a small elastic force, while the second spring 6 is short and thick and has a large elastic force. The placement of the first spring 5 facilitates the pre-positioning installation of the elastically pushing top rod 3, and the small elastic force facilitates the adjustment of the telescopic length. The placement of the second spring 6 further provides elastic stroke compensation, especially... Prolonged fixed installation can easily lead to deformation, causing the curtains to loosen and fall off. The second spring 6 can provide elastic displacement at any time to compensate, preventing the curtains from falling off over time. For example, after the top block 4 on the top rod 3 is pre-installed and abuts against the mounting surface, the electric drive module 2 drives the lead screw 7 to drive the first slider 8 to push the second spring 6. The second spring 6 pushes the second slider 9 until the first clamping block 10 and the second clamping block 11 on the second slider 9 clamp the top rod 3. At this time, the first clamping block 10, the second clamping block 11, and the top rod 3 are interlocked, and the top rod 3 is pressed tightly against the mounting surface. The second slider 9 also stops moving forward, while the first slider 8 continues to move forward, pressing the second spring 6 until it locks. The electric drive module 2 stops working. If only one spring is used, if the elastic force is too small, although it is convenient to pre-position and adjust the telescopic length of the top rod 3, the elastic force is easily lost after long-term installation, the service life of the elastically pressed spring is short, and the problem of the curtain falling off is easy to occur. If the elastic force is too large, it will be more difficult to adjust the telescopic length of the top rod 3, but the installation and use time can be longer and it is not easy to fall off. Therefore, the first spring 5 and the second spring 6 are used in combination, which can both save time and effort. The adjustable top rod 3 allows for convenient pre-positioning and adjustment of its telescopic length, preventing curtains from falling over time and extending its lifespan for enhanced safety. Furthermore, the separate placement of the first spring 5 and the second spring 6—with the first spring 5 positioned at the end of the top rod 3 away from the locking module and the second spring 6 located within the locking module between the first slider 8 and the second slider 9—reduces the drive stroke of the electric drive module 2, resulting in a smaller compression range. This leads to shorter locking time, faster locking and unlocking, and allows for the selection of a lower-power electric drive module 2, resulting in lower costs.

[0041] Referring to Figures 2, 3, and 6, a first signal switch 14 is provided at the end of the first slider 8 near the electric drive module 2, and a second signal switch 15 is provided at the end of the first slider 8 near the second slider 9. The first signal switch 14 is used to sense the travel position of the first slider 8 when it is retracted to unlock, and the second signal switch 15 is used to sense the travel position of the first slider 8 when it is forward to lock. When the first signal switch 14 and the second signal switch 15 sense the set travel position, the electric drive module 2 will stop working, completing the unlocking and locking. The setting of the first signal switch 14 and the second signal switch 15 allows the electric drive module 2 to provide controllable unlocking and locking travel, avoiding excessive compression of the second spring 6 and damage to adjacent components. It can provide controllable locking force, extend service life, and also provide the electric drive module 2 with optimal drive travel, that is, the moving distance of the first slider 8 is controllable, avoiding the electric drive module 2 from over-driving the lead screw 7 to move the first slider 8, saving time and electricity.

[0042] The electric drive module 2 is a motor, which includes a mechanism and a reducer. The motor provides power for the rotation of the lead screw 7, which is stable and labor-saving, and realizes electric operation.

[0043] As shown in Figure 8, a top beam mounting assembly includes a top beam 16. One end of the top beam 16 is connected to a curtain-free electric mounting device as described above. The end face of the end cap 1.2 is in contact with the end of the top beam 16. The other end of the top beam 16 is connected to a cover 17. The cover 17 is not limited to a cover in the ordinary sense, but also includes the side end of a motor device, power supply device, transmission device, etc. When the motor device, power supply device, transmission device are inserted into the top beam, they can cover the end of the top beam.

[0044] During assembly, the electric curtain installation device without drilling is inserted into the top beam 16, and the other end of the top beam 16 is inserted into the cover 17. The curtain body can be installed below the top beam 16. During installation, the top block 4 is pressed against the mounting wall, and the other end of the top beam 16 is pressed against the opposite mounting wall. The top block 4 is pushed by the elastic force of the first spring 5, which allows the top beam 16 to be supported in the installation position to complete the pre-positioned installation. Then the drive motor works, and the motor drives the lead screw 7 to rotate, so that the first slider 8 on the lead screw 7 slides along the lead screw 7 towards the second slider 9. The first slider 8 pushes the second spring 6 and the second slider 9, so that the first clamping block 10 and the second clamping block 11 inside the second slider 9 are subjected to the inclined surface of the trapezoidal groove 13.2 on the limiting member 13 during synchronous movement with the second slider 9. Radial compression occurs when the inclined surfaces of trapezoidal groove 13.2 and trapezoidal blocks 10.2 and 11.2 slide against each other, causing the first clamping block 10 and the second clamping block 11 to move closer together and clamp the top rod 3. Specifically, the toothed surfaces 10.4 and 11.4 on the first clamping block 10 and the second clamping block 11 engage with the toothed surfaces 3.3 on the top rod 3, stopping the second slider 9 from moving forward. At this time, the first slider 8 continues to slide along the lead screw 7 towards the second slider 9, compressing the second spring 6. When the second signal switch 15 on the first slider 8 senses the forward locking position of the first slider 8, the motor stops working, thus locking the top rod 3 and preventing axial movement, completing the fixed installation. After the top beam 16 has been installed for a long time, the elasticity of the second spring 6 can be adjusted according to the situation. The second push pushes the second slider 9, the first clamping block 10, the second clamping block 11, the top rod 3, and the top block 4, ensuring that the top block 4 remains firmly against the mounting wall, preventing it from easily falling off and ensuring stable installation. During disassembly, the drive motor rotates in the reverse direction, causing the motor-driven lead screw 7 to rotate in the reverse direction as well. This causes the first slider 8 on the lead screw 7 to move away from the second slider 9. When the first signal switch 14 on the first slider 8 senses the unlocked travel position of the first slider 8, the motor stops working, releasing the second spring 6. Simultaneously, the second slider 9 loses its axial pushing force. At this point, the springs between the first clamping block 10 and the second clamping block 11 push the first clamping block 10 and the second clamping block 11 away from each other, causing the trapezoidal blocks on the first clamping block 10 and the second clamping block 11 to... 10.2 and 11.2 are reset to the trapezoidal groove 13.2 of the limiting member 13, the first clamping block 10 and the second clamping block 11 disengage from the top rod 3, so that the top rod 3 is unlocked. By squeezing the top block 4, the top rod 3 can be pushed to move axially, thereby removing the top beam 16 from the installation position. During the locking and unlocking process of the top rod 3, the first slider 8 is electrically driven to move back and forth by the motor, and the spring is reset and unlocked. No manual operation is required, which is convenient, time-saving and labor-saving. In addition, the second signal switch 15 on the first slider 8 can sense the forward locking position of the first slider 8, so that the motor can provide a controllable locking force and will not over-compress the second spring 6. In addition, the end cover 1.2 is detachably connected to the limiting member 13 on the housing 1.2. Easy to replace, it can adapt to different sizes of top beams (16), thus accommodating windows of different widths, offering a wide range of installation compatibility. Furthermore, the telescopic length is adjustable, further expanding its applicability. It also features electric, drill-free installation, making it convenient, time-saving, and labor-saving.
