Description

Electric, no-drill installation device for curtains and its top beam mounting assembly. Technical Field

[0001] This invention relates to the field of curtain technology, and in particular to an electric, non-drilling installation device for installing curtains 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. Furthermore, drilling 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 perform the operation, making installation cumbersome, time-consuming, and labor-intensive.

[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 an electric no-drill installation device for installing curtains and its top beam installation component, which can electrically control the installation of curtains without drilling, making the installation convenient, quick and easy, saving time and effort.

[0005] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: an electric non-drilling installation device for installing curtains, including a housing, one end of which is connected to an end cap, and a cavity inside the housing. A power component, a clamping component, and an elastic adjustment component are sequentially installed in the cavity from the end away from the end cap towards the end cap. The power component is fixed in the cavity, and its power output end is driven to connect to the clamping component. One end of the elastic adjustment component abuts against the clamping component, and the other end abuts against the end cap. The end of the elastic adjustment component that abuts against the end cap partially passes through the end cap and protrudes outside the housing for pre-positioning. The elastic adjustment component has an elastic extension stroke, and the power component drives the clamping component to clamp or release the elastic adjustment component.

[0006] Furthermore, the clamping assembly includes a lead screw and a slider threadedly connected to the lead screw. The end of the lead screw away from the slider is connected to the power output end of the power component. The end of the slider away from the lead screw abuts against the elastic adjustment assembly. The slider reciprocates linearly along the length of the lead screw by rotating the lead screw to clamp or release the elastic adjustment assembly.

[0007] Furthermore, the elastic adjustment assembly includes a push rod and a first spring and a second spring sleeved on the push rod. A baffle is provided between the first spring and the second spring. The push rod has an annular protrusion. In its natural state, one end of the first spring abuts against the annular protrusion and the other end abuts against the baffle. One end of the second spring abuts against the baffle and the other end abuts against the slider. The annular protrusion abuts against the end cover. A portion of the push rod passes through the end cover and protrudes outside the housing for pre-positioning.

[0008] Furthermore, the elastic force of the second spring is greater than that of the first spring.

[0009] Furthermore, the slider is provided with a central hole for avoiding the push rod, and the lead screw is provided with a central channel for avoiding the push rod.

[0010] Furthermore, the lead screw is provided with an external thread, and the slider is provided with an internal thread that mates with the external thread.

[0011] Furthermore, the power component is an electric motor.

[0012] Furthermore, a circuit board is provided inside the housing, and the motor is electrically connected to the circuit board. A current sensor is provided on the circuit board. When the current sensor detects that the operating current of the motor is greater than a set value, the circuit board controls the motor to stop working.

[0013] A top beam mounting assembly includes a top beam and an electric no-drill mounting device as described above. The electric no-drill mounting device is mounted on one end of the top beam. A first cover and a second cover are respectively connected to both ends of the top beam. The first cover is fixedly connected to the electric no-drill mounting device. A top block is slidably mounted on the first cover. The top block is connected to an elastic adjustment component exposed outside the housing for abutting against the mounting wall to achieve pre-positioning.

[0014] Furthermore, the first cover is provided with a mounting cavity for the top block to slide linearly, and the mounting cavity has a through hole for the elastic adjustment component exposed outside the outer shell to pass through.

[0015] Compared with the prior art, the advantages of the present invention are as follows: The present invention achieves pre-positioning installation by means of the elastic adjustment component having elastic extension and retraction stroke, and then the elastic adjustment component is pressed by the power component electrically controlled clamping component to complete the fixed installation. When disassembling, the power component electrically controlled clamping component releases the elastic adjustment component, so that the elastic adjustment component can elastically extend and retract to adjust the length, thereby realizing the disassembly of the curtain. During this process, locking and unlocking are completed electrically by the power component, without the need for manual operation, which is convenient to use and saves time and effort.

Detailed Implementation

[0027] The present invention will be further described below with reference to specific embodiments.

[0028] 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.

[0029] 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.

[0030] 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.

[0031] 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.

[0032] As shown in Figures 1-5, the present invention provides an electric, non-drilling installation device for installing curtains, comprising a housing 1, one end of which is connected to an end cap 2. A cavity 1.1 is provided inside the housing 1. Within the cavity 1.1, a power component 3, a clamping assembly, and an elastic adjustment assembly are sequentially installed from the end furthest from the end cap 2 toward the end cap 2. The power component 3 is fixed within the cavity 1.1, and its power output end is connected to the clamping assembly. One end of the elastic adjustment assembly abuts against the clamping assembly, and the other end abuts against the end cap 2. The end of the elastic adjustment assembly that abuts against the end cap 2 partially protrudes outside the housing 1 for pre-positioning. The elastic adjustment assembly has an elastic extension / retraction stroke. The power component 3 drives the clamping assembly to clamp or release the elastic adjustment assembly.

[0033] This invention achieves pre-positioning installation through the elastic adjustment component with its elastic extension and retraction stroke. Then, the power component 3 electrically controls the clamping component to press the elastic adjustment component to complete the fixed installation. During disassembly, the power component 3 electrically controls the clamping component to release the elastic adjustment component, allowing the elastic adjustment component to elastically extend and retract to adjust its length, thereby realizing the disassembly of the curtain. During this process, the power component 3 electrically completes the locking and unlocking, eliminating the need for manual operation, making it convenient to use and saving time and effort.

[0034] Referring to Figures 3 and 4, the clamping assembly includes a lead screw 4 and a slider 5 threadedly connected to the lead screw 4. The end of the lead screw 4 away from the slider 5 is connected to the power output end of the power component 3. The end of the slider 5 away from the lead screw 4 abuts against the elastic adjustment component. The slider 5 reciprocates linearly along the length of the lead screw 4 to clamp or release the elastic adjustment component through the rotation of the lead screw 4. For example, when the power component 3 drives the lead screw 4 to rotate clockwise, the slider 5 on the lead screw 4 moves along the thread towards the elastic adjustment component, thereby compressing the elastic extension stroke of the elastic adjustment component and playing a locking role. This can further lock and fix the pre-positioned installation without manual locking, making operation convenient. When the power component 3 drives the lead screw 4 to rotate counterclockwise, the slider 5 on the lead screw 4 moves along the thread towards the power component 3, thereby releasing the elastic extension stroke of the elastic adjustment component and playing an unlocking role. This allows the elastic adjustment component to adjust its length within a certain range, facilitating disassembly.

[0035] Referring to Figures 2, 3, and 4, the elastic adjustment assembly includes a top rod 6 and a first spring 7 and a second spring 8 sleeved on the top rod 6. A baffle 9 is provided between the first spring 7 and the second spring 8. The top rod 6 has an annular protrusion 6.1. In its natural state, one end of the first spring 7 abuts against the annular protrusion 6.1 and the other end abuts against the baffle 9. One end of the second spring 8 abuts against the baffle 9 and the other end abuts against the slider 5. The annular protrusion 6.1 abuts against the end cover 2, forming an axial limit. A portion of the top rod 6 passes through the end cover 2 and protrudes outside the outer shell 1 for pre-positioning. For example, by pressing the top rod 6 protruding outside the outer shell 1 against the mounting wall, the elastic extension and contraction of the first spring 7 and the second spring 8 can be used to adjust the length of the top rod 6 extending out of the outer shell 1 for pre-positioning installation. Then, the power component 3 drives the lead screw 4 to link the slider 5 to squeeze or release the first spring 7 and the second spring 8, thereby achieving locking and unlocking.

[0036] The second spring 8 has a greater elastic force than the first spring 7. The first spring 7 is slender and long, while the second spring 8 is short and thick. The first spring 7 has a smaller elastic force and a larger range of adjustable length, which is mainly suitable for the telescopic length of the top rod 6 during pre-positioning installation. The second spring 8 has a larger elastic force and a smaller range of adjustable length, which can compensate for the length deformation caused by long-term use during fixed installation, preventing the curtain from falling off after prolonged installation. For example, if only one spring is used, if the elastic force is too small, although it is convenient to adjust the telescopic length of the top rod 6 during pre-positioning installation, the elastic force is easily lost after prolonged installation, causing the curtain to fall off. If the elastic force is too large, the telescopic length adjustment of the top rod 6 will be more difficult, but the installation and use time can be longer, and it is not easy to fall off. Therefore, the use of the first spring 7 and the second spring 8 in combination can not only facilitate the adjustment of the telescopic length of the top rod 6 during pre-positioning installation, but also prevent the curtain from falling off after prolonged installation, resulting in a longer service life and greater safety.

[0037] Referring to Figures 3, 4, and 5, the slider 5 is provided with a central hole 5.1 to avoid the top rod 6, and the lead screw 4 is provided with a central channel 4.1 to avoid the top rod 6. When the top rod 6 moves back and forth along its own length, the central hole 5.1 and the central channel 4.1 allow the top rod 6 to move without obstruction. The lead screw 4 is provided with an external thread 4.2, and the slider 5 is provided with an internal thread 5.2 that mates with the external thread 4.2. The slider 5 moves back and forth in a straight line along the length of the lead screw 4 through the mating of the internal thread 5.2 and the external thread 4.2.

[0038] Referring to Figures 2, 3, and 4, the power component 3 is a motor, which includes a mechanism and a reducer. The motor provides power for the rotation of the lead screw 4. A circuit board 10 is provided inside the housing 1, and the motor is electrically connected to the circuit board 10. A current sensor 11 is provided on the circuit board 10. When the current sensor 11 senses that the motor's operating current is greater than a set value, the circuit board 10 controls the motor to stop working. The current sensor 11 allows the motor to provide a controllable locking force. Since the tighter the first spring 7 and the second spring 8 are compressed, the greater the elastic force generated, and the motor requires a larger operating current, the current sensor 11 can sense the motor's operating current and control the motor to provide a controllable locking force, preventing the lead screw 4 from being over-driven and the slider 5 from squeezing the first spring 7 and the second spring 8.

[0039] As shown in Figures 6-8, a top beam mounting assembly includes a top beam 12 and an electrically operated, non-drilling mounting device as described above. The electrically operated, non-drilling mounting device is mounted on one end of the top beam 12. A first cover 13 and a second cover 14 are respectively connected to both ends of the top beam 12. The second cover 14 includes not only components commonly used to cover the ends of the top beam 12, but also components connected to the ends of the top beam 12 that provide a covering effect, such as the ends of a drive device, transmission device, or power supply device. The first cover 13 is fixedly connected to the electrically operated, non-drilling mounting device. Preferably, the first cover 13 is detachably connected to an end cap 2. A top block 15 slides onto the first cover 13, and the top block 15 is exposed on the outer casing 1. The external elastic adjustment component is connected to the mounting wall to achieve pre-positioning. Preferably, the top block 15 is connected to the end of the top rod 6 exposed outside the outer shell 1, which can increase the contact surface with the mounting wall. The first cover 13 is provided with a mounting cavity 13.1 for the top block 15 to slide linearly. The mounting cavity 13.1 has a through hole 13.2 for the elastic adjustment component exposed outside the outer shell 1 to pass through. Preferably, the through hole 13.2 allows the top rod 6 exposed outside the outer shell 1 to pass through. This structure facilitates the replacement of the first cover 13, the second cover 14 and the top block 15, making the electric no-drill installation device adaptable to different models of top beams 12, making assembly more flexible, applicable to a wide range of applications, and enabling quick electric no-drill installation of curtains, saving time and effort.

[0040] In use, the electric no-drill installation device is connected to the first cover 13 and the top block 15, and then inserted into one end of the top beam 12. The second cover 14 is connected to the other end of the top beam 12. A curtain can be installed below the top beam 12. First, the end of the top beam 12 with the top block 15 is pressed against the mounting wall, and then the other end of the top beam 12 is pressed against the opposite mounting wall. The elastic force of the first spring 7 and the second spring 8 pushing the top rod 6 outwards is used to position the top beam 12 on the window frame. Then, the motor is driven to work, and the motor drives the lead screw 4 to rotate, causing the slider 5 to slide along the lead screw 4 towards the second spring 8, thereby compressing the first spring 7 and the second spring 8. When the current sensor 11 senses that the motor's working current has reached a predetermined value, the circuit board 10 controls the motor to stop working, thus compressing the first spring 7 and the second spring 8. The motor contracts, thus locking the top rod 6, so that the top beam 12 is fixedly installed on the window frame. The motor can provide controllable locking force according to the preset working current value and can realize electric operation, saving time and effort. In actual use, the elasticity of the second spring 8 can compensate for the length due to deformation caused by long-term use during fixed installation, preventing it from falling off easily after a long time. In addition, when disassembling, the drive motor rotates in the opposite direction, and the motor drives the lead screw 4 to rotate, so that the slider 5 slides away from the second spring 8 along the lead screw 4, thereby releasing the first spring 7 and the second spring 8, unlocking the top rod 6, so that the top rod 6 has an adjustable length range, thereby allowing the top beam 12 to be removed from the window frame. During the locking and unlocking process of the top rod 6, the slider 5 is moved back and forth by electric drive of the motor, without the need for manual operation, which is convenient, time-saving and labor-saving.

[0041] Unless otherwise specified, the materials, reagents, and experimental equipment involved in the embodiments of this invention are all commercially available products in the curtain industry.
