Description

Technical Field

[0001] This application relates to the field of roller blind technology, specifically a high-light-blocking roller blind that is easy to adjust and fix. Background Technology

[0002] High-light-blocking roller blinds are widely used in places that require light protection and heat insulation. Their core requirement is to achieve the light-blocking effect while ensuring that the roller blinds are easy to open and close, and that the position adjustment is precise and stable.

[0003] In the prior art, Chinese utility model patent CN216841374U discloses a self-resetting, adjustable, and fixed high-light-blocking roller blind. It achieves self-resetting and maximum position adjustment of the blind fabric through a retractable adjustment and fixing mechanism, while a squeezing mechanism ensures tight winding of the blind fabric and also provides a cleaning function. This solution effectively reduces the difficulty of resetting and adjusting the blind fabric and improves winding stability. However, the above solution only fixes the installation position of the blind fabric and does not limit the lower frame of the blind at the bottom. When the blind fabric is adjusted to a specific length, the lower frame is suspended in the air, and under external force, it is prone to causing the lower end of the blind fabric to swing back and forth, resulting in collisions between the lower frame and the window frame or surrounding structures, generating noise and affecting the user experience.

[0004] Therefore, this application provides a high-light-blocking roller blind that is easy to adjust and fix, in order to solve the above-mentioned problems. Utility Model Content

[0005] This application provides a high-light-blocking roller blind that is easy to adjust and fix, aiming to solve the problems mentioned in the background art, such as existing high-light-blocking roller blinds can only fix the installation position of the roller blind fabric and cannot fix the lower frame of the roller blind, which makes it easy for it to swing under the influence of external forces after adjustment, and cause noise when it hits the window frame.

[0006] To achieve the above objectives, this application provides the following technical solution: a high-light-blocking roller blind that is easy to adjust and fix, comprising a roller blind body, mounting seats on both sides of the roller blind body, an adjustment mechanism for driving the roller blind body to roll up or lower between the two mounting seats, and a roller blind lower frame fixedly connected to the lower end of the roller blind body.

[0007] To facilitate the securing of the roller blind lower frame, a locking mechanism is provided. This mechanism includes symmetrical horizontal openings on the sun-facing side of the lower frame, guide plates inserted into these openings, crossbars fixedly connected to the outer ends of the guide plates for contact with the inner wall of the window frame, and a driving component for moving the two guide plates closer together or further apart. The guide plates and crossbars form an L-shape. When the lower frame needs to be secured, the driving component activates, causing the two guide plates to move away from each other along the horizontal openings, thus synchronizing the movement of the crossbars on the outer sides of the guide plates. The end of the crossbar furthest from the guide plate contacts the inner wall of the window frame. Through the symmetrical contact force of the two crossbars, the lower frame is stably secured between the window frames, thereby limiting its swaying.

[0008] Preferably, to improve the stability of the crossbar against the inner wall of the window frame: an anti-slip pad is fixedly connected to the end of the crossbar away from the guide plate, and the end of the anti-slip pad away from the crossbar is provided with anti-slip texture. Providing an anti-slip pad and anti-slip texture at the end of the crossbar significantly increases the contact friction between the crossbar and the inner wall of the window frame, preventing the crossbar from slipping due to slight shaking caused by external forces, further improving the stability of the roller shutter's lower frame fixation, and ensuring that the locking mechanism maintains a reliable fixing effect during long-term use.

[0009] Preferably, to facilitate the movement of the two guide plates closer to or further apart, the driving component includes a dual-axis motor fixedly installed within the lower frame of the roller shutter. Both output shafts of the dual-axis motor are fixedly connected to lead screws rotatably connected to the lower frame of the roller shutter, and the threads on the two lead screws are arranged in opposite directions. A slider, fixedly connected to the guide plate, is threaded onto the lead screw. This driving structure, employing a dual-axis motor with reverse-threaded lead screws, enables synchronous and stable control of the movement of the two guide plates, offering advantages such as high transmission efficiency, high control precision, and compact structure. Symmetrical extension or retraction of the crossbars on both sides can be achieved without an additional synchronization mechanism, making operation convenient and highly reliable.

[0010] Preferably, to facilitate the supply of power to the dual-axis motor: a photovoltaic panel is fixedly embedded on the sun-facing side of the lower frame of the roller shutter; a control module electrically connected to the photovoltaic panel is installed inside the lower frame; a battery electrically connected to the control module is also installed inside the lower frame; and an inverter electrically connected to the battery is further installed inside the lower frame. The inverter is electrically connected to the dual-axis motor. By integrating the photovoltaic panel and energy storage and conversion system on the lower frame of the roller shutter, solar energy is used to supply power to the dual-axis motor, eliminating the need for an external power supply and achieving self-sufficiency in power supply for the locking mechanism. This design not only simplifies the installation process but also reduces energy consumption, improves the environmental adaptability of the equipment, and conforms to the concept of green energy conservation.

[0011] Preferably, the adjustment mechanism includes a tubular motor fixedly installed between the two mounting bases. A roller shutter tube connected to its output end is sleeved on the tubular motor, and the roller shutter tube is fixedly connected to the upper end of the roller shutter body. The adjustment mechanism using a tubular motor to drive the roller shutter tube can automatically control the rolling and lowering of the roller shutter body, offering advantages such as convenient operation and smooth running. Compared to traditional manual adjustment methods, it significantly reduces the difficulty of user operation and allows for precise control of the roller shutter body's height through motor speed and direction, meeting the shading needs of different scenarios.

[0012] Preferably, to facilitate the protection of the roller blind body after it has been rolled up: a protective sleeve fixedly connected to the mounting base is fitted around the outside of the roller blind tube, and an opening is provided at the bottom of the protective sleeve for the roller blind body to pass through. The protective sleeve on the outside of the roller blind tube provides physical protection for the rolled-up roller blind body, effectively preventing dust, moisture, and debris from entering the roller blind tube area, avoiding contamination or aging of the roller blind body surface due to long-term exposure, extending the service life of the roller blind body, and maintaining its high light-blocking performance.

[0013] This application utilizes a locking mechanism on the lower frame of the roller blind, employing a drive component to move a guide plate and a horizontal bar, causing the horizontal bar to contact the inner wall of the window frame, thus fixing the position of the lower frame. This design effectively solves the impact noise problem caused by the suspended swing of the lower frame in existing technologies, avoids frequent collisions between the lower frame and the window frame, and reduces wear on the edges of the roller blind fabric and loosening of connecting parts caused by swinging, thereby improving the stability of the device.

[0014] This application provides physical protection for the roller shutter body after it is rolled up by installing a protective sleeve on the outside of the roller shutter tube. This effectively blocks dust, moisture, debris and other contaminants from entering the roller shutter tube area, preventing the surface of the roller shutter body from becoming contaminated or aging due to long-term exposure, thus extending the service life of the roller shutter body and maintaining its high light-blocking performance.

[0015] This application integrates photovoltaic panels and an energy storage and conversion system onto the lower frame of the roller shutter, utilizing solar energy to power the dual-shaft motor without requiring an external power cord, thus achieving self-sufficiency in power supply for the locking mechanism. This design not only simplifies the installation process but also reduces energy consumption, improves the equipment's environmental adaptability, and aligns with green energy-saving principles.

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0023] Example 1

[0024] This embodiment provides a high-light-blocking roller blind that is easy to adjust and fix, such as Figure 1-4 As shown, the roller blind includes a roller blind body 1, and mounting seats 2 are provided on both sides of the roller blind body 1. An adjustment mechanism 3 for driving the roller blind body 1 to roll up or lower is provided between the two mounting seats 2. A roller blind lower frame 4 is fixedly connected to the lower end of the roller blind body 1.

[0025] To facilitate the fixing of the lower roller blind frame 4, a locking mechanism 5 is provided on the lower roller blind frame 4. The locking mechanism 5 includes symmetrical horizontal openings 51 on the sun-facing side of the lower roller blind frame 4, guide plates 52 inserted into the horizontal openings 51, a crossbar 53 fixedly connected to the outer end of the guide plates 52 for contact with the inner wall of the window frame, and a driving component 54 for driving the two guide plates 52 to move closer or further apart. The guide plates 52 and the crossbar 53 are combined to form an L-shape. By setting the locking mechanism 5 on the lower roller blind frame 4, the driving component 54 drives the guide plates 52 to move the crossbar 53, causing the crossbar 53 to contact the inner wall of the window frame, thus fixing the position of the lower roller blind frame 4. This design effectively solves the impact noise problem caused by the swinging of the lower roller blind frame 4 in the prior art, avoids frequent collisions between the lower roller blind frame 4 and the window frame, and reduces wear on the edges of the roller blind fabric and loosening of connecting parts caused by swinging, thereby improving the stability of the device. When it is necessary to fix the lower roller shutter frame 4, the drive unit 54 is activated and drives the two guide plates 52 to move away from each other along the transverse opening 51, so that the crossbars 53 on the outer side of the guide plates 52 move synchronously. The end of the crossbar 53 away from the guide plate 52 is in close contact with the inner wall of the window frame. Through the symmetrical contact force of the two crossbars 53, the lower roller shutter frame 4 is stably fixed between the window frames, thereby limiting its swing.

[0026] To improve the stability of the horizontal bar 53 in contact with the inner wall of the window frame, an anti-slip pad 531 is fixedly connected to the end of the horizontal bar 53 away from the guide plate 52. The end of the anti-slip pad 531 away from the horizontal bar 53 has anti-slip textures. The anti-slip pad 531 and anti-slip textures at the end of the horizontal bar 53 significantly increase the contact friction between the horizontal bar 53 and the inner wall of the window frame, preventing the horizontal bar 53 from slipping due to slight shaking caused by external forces. This further improves the stability of the lower roller shutter frame 4 during fixing, ensuring that the locking mechanism 5 maintains a reliable fixing effect during long-term use. The anti-slip pad 531 is made of elastic material, deforming and conforming to the inner wall of the window frame when in contact. Its surface anti-slip textures increase the roughness of the contact surface, enhancing the contact force through friction. When the horizontal bar 53 is subjected to external force, the elastic deformation and texture structure of the anti-slip pad 531 together hinder the displacement of the horizontal bar 53, maintaining its fixed state.

[0027] To facilitate the movement of the two guide plates 52 closer together or further apart, the drive unit 54 includes a dual-axis motor 541 fixedly installed within the lower frame of the roller shutter 4. Both output shafts of the dual-axis motor 541 are fixedly connected to lead screws 542 rotatably connected to the lower frame of the roller shutter 4, with the threads on the two lead screws 542 arranged in opposite directions. Slider blocks 543, fixedly connected to the guide plates 52, are threaded onto the lead screws 542. This drive structure, using a dual-axis motor 541 in conjunction with the reverse-threaded lead screws 542, can synchronously and stably control the movement of the two guide plates 52, offering advantages such as high transmission efficiency, high control precision, and a compact structure. Symmetrical extension or retraction of the crossbars 53 on both sides can be achieved without an additional synchronization mechanism, making operation convenient and highly reliable. After the dual-axis motor 541 starts, the output shafts at both ends drive the lead screws 542 to rotate in the same direction. Because the threads on the two lead screws 542 are in opposite directions, the sliders 543 fitted onto the lead screws 542 will move in opposite linear directions along the lead screws 542 (one to the left, one to the right). The slider 543 is fixedly connected to the guide plate 52, thereby causing the guide plate 52 to move away from or closer to each other within the transverse opening 51, so as to realize the removal and fixing or retraction and reset of the crossbar 53.

[0028] The adjustment mechanism 3 includes a tubular motor 31 fixedly installed between two mounting bases 2. A roller blind tube 32 connected to its output end is sleeved on the tubular motor 31 and fixedly connected to the upper end of the roller blind body 1. The adjustment mechanism 3, using the tubular motor 31 to drive the roller blind tube 32, can automatically control the winding and lowering of the roller blind body 1, offering advantages such as convenient operation and smooth running. Compared to traditional manual adjustment methods, it significantly reduces the difficulty of user operation and allows for precise control of the height of the roller blind body 1 through motor speed and direction, meeting the shading needs of different scenarios. The tubular motor 31 is fixedly installed between the two mounting bases 2, with its output end connected to the roller blind tube 32. When the motor rotates forward, the roller blind tube 32 winds up the roller blind body 1, causing the roller blind to rise; when rotating in the reverse direction, the roller blind tube 32 releases the roller blind body 1, causing the roller blind to lower. By controlling the number of rotations or the time of the motor, the unfolded length of the roller blind body 1 can be precisely adjusted.

[0029] To facilitate the protection of the roller blind body 1 after it is rolled up, a protective cylinder 321, which is fixedly connected to the mounting base 2, is fitted onto the outside of the roller blind tube 32. The bottom of the protective cylinder 321 has an opening for the roller blind body 1 to pass through. The protective cylinder 321 provides physical protection for the rolled-up roller blind body 1, effectively preventing dust, moisture, and debris from entering the roller blind tube 32 area. This avoids contamination or aging of the roller blind body 1 due to long-term exposure, extending its service life while maintaining its high light-blocking performance. The protective cylinder 321 is fixed to the mounting base 2 and fitted onto the outside of the roller blind tube 32, with the bottom opening allowing the roller blind body 1 to pass freely. When the roller blind body 1 is rolled up to the roller blind tube 32, the protective cylinder 321 forms a closed protective space, isolating the roller blind body 1 from the direct influence of the external environment. When lowered, the roller blind body 1 extends out from the opening without affecting normal use.

[0030] Example 2

[0031] Unlike Embodiment 1, to facilitate the supply of power to the dual-axis motor 541, a photovoltaic panel 6 is fixedly embedded on the sun-facing side of the roller shutter lower frame 4. A control module 61 electrically connected to the photovoltaic panel 6 is installed inside the roller shutter lower frame 4, along with a battery 62 electrically connected to the control module 61. An inverter 63 electrically connected to the battery 62 is also installed inside the roller shutter lower frame 4, and the inverter 63 is electrically connected to the dual-axis motor 541. By integrating the photovoltaic panel 6 and the energy storage and conversion system onto the roller shutter lower frame 4, solar energy is used to power the dual-axis motor 541, eliminating the need for an external power supply and achieving self-sufficiency in power supply for the locking mechanism 5. This design not only simplifies the installation process but also reduces energy consumption, improves the environmental adaptability of the equipment, and aligns with the concept of green energy conservation. The photovoltaic panel 6 converts solar energy into electrical energy, which is then rectified by the control module 61 and stored in the battery 62. When the dual-shaft motor 541 needs to be driven, the battery 62 outputs DC power, which is converted into AC power suitable for the motor by the inverter 63, providing power to the drive unit 54. The control module 61 is also responsible for managing the input and output of electrical energy to ensure stable system operation.

[0032] The wiring diagrams of the tubular motor 31 and the dual-shaft motor 541 in this utility model are common knowledge in the field. Their working principles are known technologies. The appropriate model is selected according to actual use. Therefore, the control method and wiring layout of the tubular motor 31 and the dual-shaft motor 541 will not be explained in detail.

[0033] The control method of this application is through a controller. The control circuit of the controller can be implemented by a person skilled in the art through simple programming. The power supply is also common knowledge in the art. Since this application is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail here.

[0034] It should be noted that many of the standard parts used in this application are available on the market, while non-standard parts can be specially customized. The connection method used in this application is also a very common method in the mechanical field, and will not be described in detail here.

[0035] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
