Description

Technical Field

[0001] This application relates to the field of roller shutter technology, specifically to a heat-insulating roller shutter door. Background Technology

[0002] Roller shutters are a type of movable enclosure system consisting of multiple slats (door panels) connected by side hinges, which rise and fall along a vertical track and roll up to a top roller. They are widely used in commercial stores, industrial plants, underground garages, and residential entrances. Their core advantages are space saving, efficient opening and closing, strong protection, and the ability to integrate anti-theft, fireproof, sound insulation, and heat insulation functions as needed.

[0003] In order to fulfill the rolling function, traditional roller shutters must have a gap between their metal slats, which results in poor airtightness and low thermal insulation performance when closed.

[0004] Because roller shutters have both "dynamic" and "static" states, material is generally not filled at the joints of the slats to ensure normal rolling. Therefore, when the roller shutter is lowered and closed, adjacent slats come into direct contact, forming significant thermal bridges. Roller shutters are generally made of metal materials such as aluminum alloy, which have good thermal conductivity. The insulation material filled in the cavities of the slats only acts on local areas and cannot block the heat conduction path dominated by the metal frame, resulting in poor overall insulation performance.

[0005] Therefore, there is a need for a roller shutter door that can improve heat preservation. Summary of the Invention

[0057] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, illustrates the present invention. Numerous specific details are set forth in the description below to provide a thorough understanding of the invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0058] The heat-insulating roller shutter door of this application can be used in occasions such as adaptive adjustment of the sealing performance of the roller shutter door, and of course it can also be used in other similar application scenarios. The following is a detailed description of a heat-insulating roller shutter door.

[0059] Example 1 See appendix Figure 1 — Figure 7The diagram shown is a structural schematic of one embodiment of a heat-insulating roller shutter door according to this application. The heat-insulating roller shutter door includes a frame 100, a guide groove 110 disposed on the frame 100, a door body formed by multiple curtains 300 connected end to end and located at least partially within the guide groove 110, and a lifting assembly 200 for driving the door body to move up and down along the guide groove 110; wherein, the curtain 300 includes a first plate 310, a second plate 320, and an installation space 330 formed by the first plate 310 and the second plate 320; a connecting structure 400 disposed on the first plate 310 for connecting adjacent first plates 310; a heat-insulating structure 500 installed on the first plate 310 and the second plate 320 and located within the installation space 330 for connecting the first plate 310 and the second plate 320 and blocking heat conduction between the first plate 310 and the second plate 320; and a heat-insulating structure 600 for filling the gaps formed between adjacent curtains 300.

[0060] It should be noted that in this application, the end face of the door that contacts the ground is the bottom surface of the door, the direction perpendicular to the bottom surface is the height direction of the door and the curtain 300, the direction of the minimum distance between the frames 100 on both sides of the door is the length direction of the curtain 300, and the direction perpendicular to the height direction and the length direction is the width direction of the curtain 300; the inner and outer planes of the multiple curtains 300 located in the guide groove 110 are respectively coplanar.

[0061] See appendix Figure 1 — Figure 4 As shown in this application, a guide seal 120 is installed in the guide groove 110. The guide seal 120 includes a guide portion 121 connected to the guide groove 110 by bolts, and a sealing portion 122 disposed in the guide portion 121 and in contact with the outer wall of the door. The sealing portion 122 is made of a material that can be elastically deformed, such as rubber, to ensure that the gap between the guide groove 110 and the door is filled, ensuring that the internal and external air cannot flow through the gap between the guide groove 110 and the door. At the same time, it ensures the stability of the door during the lifting and lowering process, so that the temperature inside and outside the door can only flow and transfer through the gap between adjacent curtains 300.

[0062] See appendix Figure 1 and Figure 2 As shown in the present application, the lifting assembly 200 includes a lifting mounting plate 210 installed on the top of the frame 100 or on the wall, a lifting shaft 220 movably installed on the lifting mounting plate 210 via a shaft seat, a lifting connecting plate 230 installed on the lifting shaft 220 and connected to the bottom of the door, and a lifting power source 240 installed on the lifting mounting plate 210 and connected to the lifting shaft 220.

[0063] This application uses a lifting shaft 220 as a rotation center shaft and a reference for winding the door body. The lifting connecting plate 230 allows the door body to rise and wind around the lifting shaft, or fall, to close the doorway when the lifting shaft 220 rotates. A lifting power source 240, which can be a motor, is used to drive the lifting shaft 220 to rotate. The motor's output shaft can be connected to the lifting shaft 220 via a key, sprocket chain, gear, or drive belt for power transmission.

[0064] See appendix Figure 5 — Figure 7 As shown, in this application, the connection structure 400 includes a first connection portion 410 disposed at the top of the first plate 310 and a second connection portion 420 disposed at the bottom of the second plate 320. Both the first connection portion 410 and the second connection portion 420 are hook-shaped and are connected by hook-fitting, so that adjacent curtains 300 can be connected. See appendix Figure 5 — Figure 7 As shown, the thermal insulation structure 500 in this application includes a first thermal insulation mounting groove 510 disposed on the side wall of the installation space 330, a first thermal insulation strip 530 installed in the first thermal insulation mounting groove 510 by interference fit, and a thermal insulation body 550 filled in the installation space 330 and located between the two first thermal insulation strips 530.

[0065] It should be noted that the thermal insulation strip can be made of thermal insulation material, specifically PA66 nylon material, and the insulation body 550 can be made of thermal insulation material, specifically polyurethane foam filling.

[0066] The application provides installation conditions for the first heat insulation strip 530 by setting the first heat installation groove 510, so that the first heat insulation strip 530 can separate and support the first plate 310 and the second plate 320; by setting the heat insulation body 550, the space for air heat exchange between the first plate 310 and the second plate 320 is reduced, thereby improving the heat insulation performance of the curtain 300.

[0067] See appendix Figure 5 — Figure 7As shown in this application, the first heat insulation strip 530 includes a heat insulation body 533 and a limiting part 534 disposed on the heat insulation body 533 and protruding from the surface of the heat insulation body 533; the first heat insulation groove 510 is provided with an installation groove 511 corresponding to the heat insulation body 533, and a limiting groove 512 disposed on the heat insulation body 533 and connected to the installation groove 511, the limiting groove 512 corresponding to the limiting part 534. It should be noted that the limiting groove 512 is only connected to the installation groove 511 and not directly connected to the installation space 330, ensuring the cooperation between the limiting groove 512 and the limiting part 534, so that the first plate 310 and the second plate 320 can be connected through the first heat insulation strip 530.

[0068] See appendix Figure 5 — Figure 7 As shown, in this application, the thermal insulation structure 600 includes a thermal insulation strip 610 located within the installation space 330. The thermal insulation strip 610 protrudes from the installation space 330, and the protrusion height is not less than the distance between adjacent curtains 300. By limiting the protrusion height of the thermal insulation strip 610 within the installation space 330, it is ensured that the thermal insulation strip 610 can fill the gap between adjacent curtains 300. In addition, since the thermal insulation strip 610 is installed within the installation space 330, when the roller shutter door is closed, the top of the thermal insulation strip 610 will be inserted into the installation space 330 of the previous curtain 300, thereby ensuring sufficient filling of the gap between adjacent curtains 300 and guaranteeing the thermal insulation performance of the roller shutter door.

[0069] See appendix Figure 1 — Figure 7 As shown, this application requires the roller shutter door 100 to close the passageway; The operator can start the lifting power source 240 via an external PLC controller electrically connected to it. The lifting power source 240 rotates, causing the lifting shaft 220 to rotate, lowering the roller shutter door along the guide groove 110 of the frame 100. As the roller shutter door lowers, the top of the insulation strip 610 inserts into the installation space 330 of the previous curtain 300 and abuts against the first insulation strip 530 in the previous curtain 300, until the lifting power source 240 rotates a specified number of times, completely lowering the roller shutter door. The first plate 310 and the second plate 320 in the roller shutter door body are in contact with the internal and external gases respectively. The gases on both sides contact the corresponding components for heat exchange. When the heat exchange reaches the insulation structure 500, a broken bridge is formed due to the influence of the first insulation strip 530 and the insulation body 550, resulting in low heat transfer efficiency. Therefore, the roller shutter door body is insulated. At the same time, the air flow inside or outside is blocked by the insulation strip 610 and the sealing element 120, preventing gas exchange and further improving the insulation effect of the roller shutter door.

[0070] Example 2 See appendix Figure 8 — Figure 20 The diagram shows a structural schematic of another embodiment of an insulated roller shutter door according to this application. The insulation strip 610 of the insulation structure 600 in the insulated roller shutter door is installed on the insulation structure 500 and located within the installation space 330, moving towards the height of the curtain 300, and the insulation structures 600 of adjacent curtains 300 are in contact with each other. The heat-insulating roller shutter door also includes a control component 700 installed at the bottom of the door body and in contact with the heat insulation structure 600 in the bottommost curtain 300 of the door body. The control component 700 has a locked state and an unlocked state. It is detachably connected to the control component 700 and is used to adjust the state of the control component 700.

[0071] It should be noted that the adjusting component 800 controls the adjusting component 700 to adjust in the width direction of the curtain 300, thereby adjusting the state of the adjusting component 700. When the adjusting component 700 is adjusted to the unlocked state, under the action of gravity and the lifting component 200, the bottom of the door is pressed against the ground. At this time, the adjusting component 700 will push the insulation structure 600 to rise, causing the insulation structure 600 to move in the height direction of the curtain 300, filling the gap between adjacent curtains 300.

[0072] The connecting structure 400 also includes a vent 430 disposed on the first connecting part 410 and the second connecting part 420. The vent 430 provides conditions for air flow inside and outside the door, and improves the air flow effect when the user needs air circulation. By disposing of the vent 430 on the first connecting part 410 and the second connecting part 420, it is affected by the heat insulation structure 600. After the heat insulation structure 600 fills the gap between the curtain 300, even if air enters the vent 430, the air inside and outside the door cannot come into contact and undergo heat conversion through the vent 430.

[0073] See appendix Figure 10 — Figure 12 As shown in the present application, the thermal insulation structure 500 further includes a second thermal insulation mounting groove 520 disposed on the side wall of the mounting space 330, a second thermal insulation strip 540 installed in the second thermal insulation mounting groove 520 by interference fit, and the bottom of the second thermal insulation strip 540 is in contact with the top of the first thermal insulation strip 530. The second thermal insulation strip 540 and the first thermal insulation strip 530 together form a thermal insulation cavity, which is filled with a thermal insulation body 550.

[0074] It should be noted that the top surface of the insulation body 550 is not higher than the top surface of the second insulation strip 540.

[0075] See appendix Figure 10 — Figure 12 As shown in the present application, the first heat insulation strip 530 is provided with a first through hole 531, and the second heat insulation strip 540 is provided with a second through hole 532 that communicates with the first through hole 531; wherein, both the first heat insulation strip 530 and the second heat insulation strip 540 include a heat insulation body 533, and the first heat insulation strip 530, and / or the second heat insulation strip 540 further includes limiting portions 534 disposed at both ends of the heat insulation body 533.

[0076] This application connects the first through hole 531 and the second through hole 532, allowing the thermal insulation structure 600 to be installed on the thermal insulation strip and to move along the thermal insulation strip in the height direction of the curtain 300. It should be noted that the diameter of the second through hole 532 is larger than that of the first through hole 531. The orthographic projection of the second through hole 532 on the top surface of the first thermal insulation strip 530 covers the orthographic projection of the first through hole 531 on the top surface of the first thermal insulation strip 530, ensuring that the thermal insulation structure 600 can move normally. The limiting part 534 is used to connect the thermal insulation strip to the first plate 310 and the second plate 320, preventing the thermal insulation strip from separating from the first plate 310 and the second plate 320. The limiting part 534 can be a protrusion or a recess.

[0077] See appendix Figure 10 — Figure 13 As shown, the insulation structure 600 also includes a first connector 620 movably installed in the second through hole 532, and a second connector 630 movably installed in the first through hole 531 and connected to the first connector 620; wherein, a limiting step 621 is provided at the connection between the first connector 620 and the second connector 630, the top of the first connector 620 is connected to the bottom of the insulation strip 610, and the top of the second connector 630 is connected to the bottom of the first connector 620. It should be noted that the maximum movement range of the insulation structure 600 is not less than the gap between adjacent curtains 300, and both the first connector 620 and the second connector 630 are columnar. See appendix Figure 14 — Figure 18 As shown in this application, the control component 700 includes a base block 710 installed at the bottom of the door body, a connection hole 720 provided in the base block 710, a lifting structure 730 movably installed in the base block 710, and a locking structure 740 movably installed in the base block 710 and movably connected to the lifting structure 730.

[0078] It should be noted that the width of the base block 710 is not greater than the width of the curtain body 300; the diameter of the connecting hole 720 is not less than the diameter of the second connecting member 630. The lifting structure 730 protrudes from the bottom surface of the base block 710.

[0079] This application uses a base block 710 to provide installation positions for the lifting structure 730 and the locking structure 740. By limiting the width of the base block 710, it ensures that the base block 710 will not interfere with the sealing element 120 during the rising process of the curtain 300, thus guaranteeing the sealing performance of the sealing element 120 on the door. The connection hole 720 is used to avoid the second connector 630, allowing the second connector 630 in the insulation structure 600 at the bottom of the door to be inserted into the connection hole 720 and contact the lifting structure 730. This allows the lifting structure 730 to lift the second connector 630 in contact with it, thereby lifting all the second connectors 630 and filling the gaps between the curtains 300 with the insulation strip 610. The locking structure 740 is used to control the lifting movement of the lifting structure 730. When the user needs air circulation, the lifting structure 730 can be restricted to prevent it from rising, thus ensuring the gap between adjacent curtains 300.

[0080] See appendix Figure 14 — Figure 18 As shown in this application, the base block 710 is provided with a first mounting groove 711 and a second mounting groove 712. The second mounting groove 712 provides mounting space for the locking structure 740, and the first mounting groove 711 provides mounting space for the lifting structure 730. The slotting directions of the first mounting groove 711 and the second mounting groove 712 are perpendicular. The lifting structure 730 moves along the first mounting groove 711 towards the height of the curtain 300. The adjusting component 800 controls the locking structure 740 to move horizontally along the second mounting groove 712 towards the width of the curtain 300, thereby locking or unlocking the lifting structure 730. It should be noted that the base block 710 is made of PA66 glass fiber reinforced nylon material.

[0081] See appendix Figure 14 — Figure 18 As shown, in this application, the lifting structure 730 includes a movable block 731 movably installed in the first mounting groove 711, a movable column 732 installed on the top of the movable block 731, a first limiting member 733 installed at the opening of the first mounting groove 711, and an abutting column 734 installed at the bottom of the movable block 731 and passing through the first limiting member 733.

[0082] In this application, the height of the movable block 731 is less than the depth of the first mounting groove 711. The movable block 731 can move within the first mounting groove 711 in the groove depth direction, i.e., in the height direction of the curtain 300, and the movable range is not less than the gap between adjacent curtains 300. The moving column 732 transmits the moving power of the movable block 731, causing the second connecting member 630 to move under the action of the moving column 732, and extending the depth of the connecting hole 720, thus strengthening the connection between the second connecting member and the connecting member. The 630 provides a guiding effect; the first limiting member 733 is used to seal the opening of the first mounting groove 711 and limit the travel of the moving block 731. This first limiting member 733 is plate-shaped. The abutment post 734 is used to contact the ground, and the bottom surface supports the abutment post 734, allowing it to move relative to the curtain 300. The abutment post 734 protrudes from the ground of the base block 710 by a length not less than the distance the insulation structure 500 needs to move. It should be noted that a rubber buffer pad can be installed at the bottom of the abutment post 734 to cushion the impact force between the abutment post 734 and the ground, extending the service life of the abutment post 734.

[0083] See appendix Figure 14 As shown in Figure 18, in this application, the locking structure 740 includes a locking member 741 movably installed in the second mounting groove 712, a control member 742 with one end installed on the locking member 741 and the other end detachably connected to the adjustment assembly 800, and a second limiting member 743 installed at the opening of the second mounting groove 712. The second limiting member 743 is provided with a first clearance groove 744 corresponding to the control member 742. It should be noted that the moving block 731 is provided with a movable groove 735 adapted to the locking member 741, the width of the control member 742 is smaller than the width of the locking member 741, and / or the height of the control member 742 is smaller than the height of the locking member 741.

[0084] This application utilizes the locking element 741, in conjunction with the movable slot 735, to prevent the moving block 731 from moving when the locking element 741 is inserted into the movable slot 735, thereby locking the moving block 731 and ensuring that the insulation structure 600 will not move and will not fill the gap between adjacent curtains 300. The control element 742 is used to drive the locking element 741 to move horizontally, separating the locking element 741 from the movable slot 735, releasing the restriction on the moving block 731, and allowing the moving block 731 to move. The second limiting element 743 is used to limit the locking element 741, preventing it from separating from the second mounting slot 712. The size of the control element 742 is used to limit the locking element 741. The first clearance slot 744 is used to allow the control element 742 to pass, allowing the control element 742 to connect with the adjustment assembly 800.

[0085] It should be noted that after the locking member 741 separates from the movable groove 735, if the abutment post 734 is not in contact with the ground, or if other external forces are applied that are sufficient to overcome gravity, the movable block 731 remains stationary, and the locking member 741 can be freely inserted into the movable groove 735, or separated from the movable groove 735; a rubber block is installed on the groove wall of the first clearance groove 744, so that the first clearance groove 744 and the control member 742 form an interference fit, increasing the maximum static friction of the control member 742, and ensuring that the control member 742 will not move arbitrarily during the raising and lowering of the curtain 300.

[0086] See appendix Figure 19 and Figure 20 As shown in this application, the adjustment assembly 800 includes an adjustment mounting bracket 810 mounted on the frame 100 or a wall, an adjustment power source 820 mounted on the adjustment mounting bracket 810, and an adjustment transmission member 830 mounted on the adjustment power source 820 and detachably connected to the control member 742.

[0087] This application provides installation conditions for adjusting the power source 820 by adjusting the setting of the mounting bracket 810 as an installation reference; by adjusting the setting of the power source 820, the power for adjusting the state of the control component 700, namely the power for moving the locking member 741 and the control member 742, is applied; the adjusting power source 820 can be an electric cylinder with a motor encoder that can precisely control the telescopic distance; by adjusting the setting of the transmission member 830, the power of the adjusting power source 820 is transmitted, so that the control member 742 can move. It should be noted that the electric cylinder is electrically connected to an external controller, allowing operators to control the extension distance of the cylinder's telescopic rod. This controller is also electrically connected to the lifting power source 240. Three sets of proximity switches for sensing the base block 710 are installed at both ends of the guide groove 110. The first set is located at the end of the guide groove 110 near the top surface, limiting the upward movement of the curtain 300. The second and third sets are located at the ends of the guide groove 110 near the ground. The second set is farther from the ground than the third set, meaning the second set of proximity switches corresponds to the situation where sealing the gap between adjacent curtains 300 is not required. In this case, the abutment post 734 cannot move, thus the extension distance of the abutment post 734 is set to avoid interference. The third set of proximity switches corresponds to the situation where sealing the gap between adjacent curtains 300 is required. In this case, the abutment post 734 can move along the height direction of the curtain 300, resulting in a lower sensing height for the base block 710. A metal sensing block can be installed on the side of the base block 710 to confirm its position.

[0088] See appendix Figure 14 — Figure 20As shown, the detachable connection structure of the control component 742 and the adjustment transmission component 830 in this application includes a mating protrusion and a mating recess. The mating protrusion and the mating recess are adapted to each other and are respectively disposed on the top surface of the control component 742 and the bottom surface of the adjustment transmission component 830. This allows the adjustment transmission component 830 to be limited by the engagement of the mating protrusion and the mating recess when it moves horizontally, but it is not limited by this structure when the curtain 300 moves in the height direction. In addition, a plane perpendicular to the length direction of the curtain 300 is made, and the orthographic projection of the mating protrusion and the mating recess on this plane is an isosceles trapezoid or an arc, which allows for guidance during connection.

[0089] See appendix Figure 8 — Figure 20 As shown, the use of the roller shutter door in this application is described as follows: When roller shutters require air circulation but do not need good thermal insulation: The user can control the adjustment component 800 to drive the control component 700 to adjust its state through the external controller, so that the control component 700 is in the locked state; then the controller controls the lifting component 200 to control the curtain 300 to descend until the controller receives the signal of the second set of proximity switches, at which point the controller controls the lifting component 200 to stop working. Specifically, the controller controls the extension of the telescopic rod of the adjusting power source 820 in the adjusting assembly 800, which drives the plate-shaped or block-shaped adjusting transmission member 830 to move. The adjusting transmission member 830 drives the control member 742 to move through the cooperation of the protrusion and the recess. The control member 742 drives the locking member 741 to move along the second mounting groove in the width direction of the curtain 300, so that the locking member 741 is inserted into the movable groove 735, limiting the movement of the moving block 731 and ensuring that the moving block 731 cannot move in the height direction of the curtain 300. The adjusting power source 820 precisely controls the movement distance of the adjusting transmission component 830 through the motor encoder, providing a basis for the subsequent resetting engagement; after the adjusting power source 820 completes the movement of the locking component 741, the controller controls the lifting power source 240 in the lifting assembly 200 to start, the lifting power source 240 drives the lifting shaft 220 to rotate, the rotation of the lifting shaft 220 causes the curtain 300 to descend along the guide groove 110 and in close contact with the sealing component 120, until the controller receives the signal from the second set of proximity switches, indicating that the curtain 300 has finished descending.

[0090] When roller shutters need to be insulated to prevent air circulation between the inside and outside: The user can control the adjustment component 800 to drive the control component 700 to adjust its state through the external controller, so that the control component 700 is in the unlocked state; then the controller controls the lifting component 200 to control the curtain 300 to descend until the controller receives the signal of the third set of proximity switches, at which point the controller controls the lifting component 200 to stop working. Specifically, the controller controls the retraction of the telescopic rod of the adjusting power source 820 in the adjusting assembly 800, which drives the adjusting transmission member 830 to move. The adjusting transmission member 830, through the engagement of the protrusion and the recess, drives the control member 742 to move. The control member 742 drives the locking member 741 to move along the second mounting groove in the width direction of the curtain 300, so that the locking member 741 separates from the movable groove 735, removing the movement restriction on the moving block 731 and ensuring that the moving block 731 can move in the height direction of the curtain 300. The adjusting power source 820 precisely controls the movement distance of the adjusting transmission member 830 through the motor encoder, providing a basis for the subsequent resetting engagement. After the adjusting power source 820 completes the movement of the locking member 741, the controller controls the lifting power source 240 in the lifting assembly 200 to start. The lifting power source 240 drives the lifting shaft 220 to rotate. The rotation of the lifting shaft 220 causes the curtain 300 to move along the guide groove 110 and into contact with the sealing member. The curtain 300 descends in a tightly pressed position. After the abutment post 734 contacts the ground, the third set of proximity switches has not yet detected the base block 710. Therefore, the lifting power source 240 continues to move, causing the curtain 300 to continue moving towards the ground. The abutment post 734, supported by the ground, cannot continue to move downwards, thus pushing the moving block 731 to move upwards relative to the curtain 300. The moving block 731 drives the moving post 732 to move, and the moving post 732 drives the second connecting member 630 to move. The second connecting member 630, through the first connecting member 620, drives the insulation strip 610 to move upwards relative to the curtain 300, filling the gaps. The bottom insulation strip 610 pushes the second connecting member 630 in the previous insulation structure 600 it contacts to move, causing the insulation strip 610 in the previous insulation structure 600 to move upwards, filling the gaps. This continues until the third set of proximity switches detects the position of the base block 710, at which point the controller stops the lifting power source 240.

[0091] The above embodiments are illustrative of this application and are not intended to limit this application. Any simple modifications to this application are within the protection scope of this application.
