Description

[Technical Field]

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

[0002] Curtains are widely used in homes, offices, and other places, primarily to adjust the lighting inside a room. Currently, roller blinds, blinds, honeycomb shades, and the like are widely used. Generally, when installing curtains, they must be secured to a window frame using mounting brackets and screws. Screw installation leaves screw holes in the window frame, which requires re-drilling holes when reinstalling or replacing curtains. Since curtains cannot be installed on the spot, multiple screw holes are inevitably left in the wall of the window frame, damaging the wall and affecting the aesthetics. Drilling holes for installation generates dust, making cleaning inconvenient, and time-consuming to install. While many no-drilling installation curtains are available on the market, conventional no-drilling assemblies require manual operation during use. They basically support the window frame with an elastic assembly, and then manually adjust a clamping restrictor to complete the installation. Most curtain installation positions have a certain installation height, requiring a person to climb up to manually install and adjust the curtains, making installation cumbersome and time-consuming.

[0020] It should be noted that the terms "first" and "second" are used merely for descriptive purposes and should not be understood to indicate or suggest relative importance or implicitly specify the number of technical features shown. Thus, a feature qualified by "first" or "second" expresses or implies the inclusion of one or more of said features. Furthermore, in the present invention, unless otherwise stated, "plurality" means two or more, e.g., two or three.

[0021] Unless otherwise specified and indicated in the present invention, the terms "attached," "coupled," "joined," "fixed," etc. should be interpreted broadly, and may refer to, for example, a solid connection, a detachable connection or integration, a mechanical connection, an electrical connection, a direct connection, an indirect connection via an intermediate element, an internal communication between two elements, or an interactive relationship between two elements, unless otherwise clearly limited. Those skilled in the art can understand the specific meaning of the above terms in the present invention according to the specific circumstances.

Furthermore, a first feature described as being "directly above," "above," and "on" a second feature may mean being directly above or diagonally above the second feature, or simply having a higher horizontal height than the second feature. A first feature described as being "directly below," "below," and "below" a second feature may mean being directly below or diagonally below the second feature, or simply having a lower horizontal height than the second feature.

[0023] As shown in Figures 1 to 5, the present invention provides an electric mounting device for mounting curtains that does not require drilling, and includes a housing 1, an end cover 2 connected to one end of the housing 1, a cavity 1.1 formed within the housing 1, a power member 3, a pressing assembly, and an elastic adjustment assembly installed in this order within the cavity 1.1 from the end away from the end cover 2 toward the end cover 2, the power member 3 being fixed within the cavity 1.1, a power output end of the power member 3 being connected to the pressing assembly so as to be able to transmit power, one end of the elastic adjustment assembly abutting the pressing assembly and the other end abutting the end cover 2, a portion of the end of the elastic adjustment assembly abutting the end cover 2 penetrating the end cover 2 and exposed to the outside of the housing 1 for temporary fastening, the elastic adjustment assembly having an elastic extension / contraction stroke, and the power member 3 driving the pressing assembly to compress or release the elastic adjustment assembly.

[0024] Compared with the prior art, the present invention has the following advantages: The elastic adjustment assembly has an elastic extension stroke, which allows temporary installation, and then the power member 3 electrically controls the pressing assembly to compress the elastic adjustment assembly to complete the permanent installation. When removing the curtain, the power member 3 electrically controls the pressing assembly to release the elastic adjustment assembly, allowing the elastic adjustment assembly to elastically extend and retract to adjust the length, thereby removing the curtain. During this process, the power member 3 completes the tightening and loosening, eliminating the need for manual operation, making it easy to use and reducing labor.

[0025] 3 and 4, the pressing assembly includes a screw rod 4 and a slider 5 threaded onto the screw rod 4, the end of the screw rod 4 remote from the slider 5 is connected to the power output end of a power member so as to transmit power, the end of the slider 5 remote from the screw rod 4 abuts against the elastic adjustment assembly, and the slider 5 moves back and forth linearly along the length of the screw rod 4 as the screw rod 4 rotates, thereby compressing or releasing the elastic adjustment assembly. For example, when the power member 3 drives the screw rod 4 to rotate clockwise, the slider 5 on the screw rod 4 moves along the thread toward the elastic adjustment assembly, compressing the elastic expansion and contraction stroke of the elastic adjustment assembly and exerting a clamping action to secure the temporary installation, eliminating the need for manual clamping and making operation convenient. When the power member 3 rotates the screw rod 4 counterclockwise, the slider 5 on the screw rod 4 moves along the thread toward the power member 3, thereby releasing the elastic expansion and contraction stroke of the elastic adjustment assembly, exerting a loosening action, allowing the length of the elastic adjustment assembly to be adjusted within a certain range, and making it easy to remove.

[0026] 2, 3, and 4, the elastic adjustment assembly comprises a tension rod 6, and a first spring 7 and a second spring 8 fitted into the tension rod 6. A stopper piece 9 is provided between the first spring 7 and the second spring 8. The tension rod 6 is provided with an annular protrusion 6.1. In a natural state, one end of the first spring 7 abuts against the annular protrusion 6.1 and the other end abuts against the stopper piece 9, one end of the second spring 8 abuts against the stopper piece 9 and the other end abuts against the slider, the annular protrusion 6.1 abuts against the end cover 2, forming an axial restriction, and a portion of the tension rod 6 penetrates the end cover 2 and is exposed to the outside of the housing 1 and is used for temporary fastening. For example, the tension rod 6 exposed outside the housing 1 can be tensioned against the mounting wall, and the length of the tension rod 6 protruding from the housing 1 can be adjusted through the elastic expansion and contraction of the first spring 7 and the second spring 8 to temporarily install it.Then, the power member 3 drives the screw rod 4, which in turn links the slider 5 to compress or release the first spring 7 and the second spring 8, thereby achieving tightening or loosening.

[0027] The elastic force of the second spring 8 is greater than that of the first spring 7. The first spring 7 is long and thin, while the second spring 8 is thick and short. The first spring 7 has a small elastic force and a wide range of elastic adjustment length, which is mainly suitable for adjusting the extension length of the tension rod 6 during temporary installation. The second spring 8 has a large elastic force and a narrow range of elastic adjustment length, which compensates for deformation caused by long-term use during permanent installation and prevents the spring from falling off easily after a certain period of time has passed since installation. 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 6 during temporary installation, but the elastic force is likely to be lost after a while after installation, causing the curtain to fall. If the elastic force is too large, it is more difficult to adjust the extension length of the tension rod 6, 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 7 and second spring 8, not only can the extension length of the tension rod 6 be easily adjusted during temporary installation, but the problem of the curtain easily falling after a while after installation can be prevented, the lifespan is longer, and it is safer.

[0028] 3, 4, and 5, the slider 5 has a central hole 5.1 for receiving the tension rod 6, and the screw rod 4 has a central channel 4.1 for receiving the tension rod 6. When the tension rod 6 moves back and forth along its length, the central hole 5.1 and central channel 4.1 allow the tension rod 6 to move without obstruction. The screw rod 4 has a male thread 4.2, and the slider 5 has a female thread 5.2 that fits the male thread 4.2. The slider 5 moves linearly back and forth along the length of the screw rod 4 through cooperation between the female thread 5.2 and the male thread 4.2.

[0029] 2, 3, and 4, the power member 3 is a motor equipped with a drive mechanism and a reducer, and the motor supplies power to rotate the screw rod 4. A circuit board 10 is provided within 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, and when the current sensor 11 detects that the operating current of the motor is greater than a set value, the circuit board 10 controls the motor to stop operating. The provision of the current sensor 11 enables the motor to provide a controllable clamping force. As the first spring 7 and the second spring 8 are compressed more strongly, the generated elastic force increases and, at the same time, the motor requires a larger operating current. Therefore, by detecting the operating current of the motor via the current sensor 11, the motor can be controlled to provide a controllable clamping force without excessively driving the screw rod 4 and engaging the slider 5 to compress the first spring 7 and the second spring 8.

[0030] As shown in Figures 6 to 8, the top frame mounting assembly includes a top frame 12 and the no-drilling electric mounting device described above. The no-drilling electric mounting device is attached to one end of the top frame 12, and a first cover cap 13 and a second cover cap 14 are respectively connected to both ends of the top frame 12. The definition of the second cover cap 14 not only includes components commonly used to shield the end of the top frame 12, but also components connected to the end of the top frame 12 and having a shielding effect on the end of the top frame 12, such as the ends of a drive unit, a transmission unit, a power supply unit, etc. The first cover cap 13 is fastened to the no-drilling electric mounting device, and preferably the first cover cap 13 and the end cover 2 are removably connected. The first cover cap 13 is attached to the no-drilling electric mounting device, and a tension block is slidably mounted on the first cover cap 13. The tension block is connected to an elastic adjustment assembly exposed outside the housing and abuts against the mounting wall to achieve temporary fastening. Preferably, the tension block 15 is exposed outside the housing 1 and connected to the end of the tension rod 6, thereby increasing the contact surface that tightly abuts against the mounting wall. The first cover cap 13 is provided with a mounting cavity 13.1 for the tension block 15 to slide linearly, and the mounting cavity 13.1 is provided with a through-hole 13.2 for inserting the elastic adjustment assembly exposed outside the housing 1. Preferably, the through hole 13.2 is used for inserting the tension rod 6 exposed outside the housing 1, and the installation of this structure makes it easy to replace the first cover cap 13, the second cover cap 14 and the tension block 15, and allows the drilling-free electric mounting device to be adapted to different model numbers of top frame 12, making the assembly more flexible and applicable in a wider range, allowing the curtain to be quickly and electrically mounted without drilling, saving effort.

[0031] In use, the drilling-free electric mounting device is connected to the first cover cap 13 and tension block 15, then inserted into one end of the top frame 12, and the second cover cap 14 is connected to the other end of the top frame 12, allowing the curtain body to be attached below the top frame 12. First, the end of the top frame 12 having the tension block 15 is placed against the mounting wall, and then the other end of the top frame 12 is placed against the opposite mounting wall, and the elastic forces of the first spring 7 and second spring 8, which press the tension rod 6 outward, are used to temporarily install the top frame 12 in the window frame, and then the top frame 12 is temporarily installed in the window frame. The motor rotates the screw rod 4, sliding the slider 5 along the screw rod 4 toward the second spring 8 and compressing the first spring 7 and the second spring 8. When the current sensor 11 detects that the motor's operating current has reached a predetermined value, the circuit board 10 controls the motor to stop, compressing the first spring 7 and the second spring 8, tightening the tension rod 6 and fastening the top frame 12 to the window frame. The motor provides a controllable tightening force according to the preset operating current, achieving electric operation and reducing labor. In actual use, the elastic force of the second spring 8 compensates for deformation due to long-term use during installation, preventing the unit from falling off easily after a certain period of time has passed since installation. Furthermore, when removing the top frame 12, the motor is rotated in the reverse direction, which rotates the screw rod 4 and causes the slider 5 to slide along the screw rod 4 in a direction away from the second spring 8, thereby releasing the first spring 7 and the second spring 8 and loosening the tension rod 6, giving the tension rod 6 an adjustable range of length, allowing the top frame 12 to be removed from the window frame. During the process of tightening the tension rod 6, the motor electrically drives the reciprocating movement of the slider 5, eliminating the need for manual operation and making it easy to use and less laborious.

[0032] Materials, reagents and test equipment according to embodiments of the present invention are commercially available products suitable for use in the curtain industry unless otherwise specified.
