Description

Technical Field

[0001] This utility model relates to the field of roller shutter door technology, and more specifically to a garage roller shutter door structure. Background Technology

[0002] In existing garage door rolling shutter technology, the rollers used for rolling up the shutter are generally fixed and cannot be moved. As the shutter rolls up onto the fixed rollers, the thickness of the roll increases, and the space between the shutter and the rollers is gradually compressed. Because there is no position adjustment mechanism, the shutter is prone to jamming during the rolling process, resulting in uneven rolling. The compression during rolling often generates significant noise, disturbing the surrounding environment of the garage. Furthermore, this continuous compression can cause deformation or even damage to the door, severely affecting its integrity, reducing its lifespan, and increasing maintenance and replacement costs for users. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the present invention provides a garage roller shutter door structure to solve the problem that the rollers of the roller shutter door are fixed and cannot be moved.

[0004] To achieve the above objectives, this utility model adopts the following technical solution:

[0005] This utility model provides a garage roller shutter door structure, including: a door frame and a door body, the door body being mounted on the door frame and used to cover the door frame; a winding roller, the winding roller being rotatably mounted on the top of the door frame, one side of the door body being connected to the winding roller, the door body being configured to be able to be wound onto the winding roller or unfolded from the winding roller to cover the door frame; a mounting base, the mounting base being fixed to the top of the door frame, and at least a portion of the mounting base being movable in a horizontal direction; the end of the winding roller being connected to a movable portion of the mounting base to enable the winding roller to move in a horizontal direction.

[0006] According to the above-mentioned technical means, in this utility model, at least part of the mounting base can move horizontally, and the end of the winding roller is connected to the movable part of the mounting base, so that the winding roller can move horizontally. During the door winding process, as the winding thickness increases, the winding roller can move horizontally in a timely manner to avoid friction and jamming between the door and the roller or other components due to space compression, thereby ensuring the smoothness of the door winding and unfolding actions. At the same time, it prevents excessive compression and friction between the door and the roller and other components, reducing noise generation at the source.

[0007] Furthermore, the mounting base includes a first guide and a movable member. The first guide is mounted on the top of the door frame and extends horizontally. The movable member is movably mounted on the first guide and is connected to the end of the take-up roller so that the take-up roller can move horizontally.

[0008] According to the above-mentioned technical means, in this embodiment, the mounting base consists of a first guide member and a moving member. The first guide member is firmly installed on the top of the door frame and extends horizontally, providing a precise horizontal movement track for the moving member. The moving member is movably installed on the first guide member and is tightly connected to the end of the winding roller. During the door's winding and unfolding process, as the winding thickness changes, the moving member can flexibly move horizontally along the first guide member, driving the winding roller to adjust its position synchronously. This effectively avoids damage to the door due to space compression, ensuring the smoothness of the door's winding and unfolding actions and greatly improving the user experience of the roller shutter door.

[0009] Furthermore, the first guide member is a first slide rail, and the moving member is a slider, with the first slide rail and the slider being adapted to each other.

[0010] Based on the aforementioned technical means, the first guide component is designed as a first slide rail, and the moving component is designed as a matching slider. This structure provides highly precise guidance for the horizontal movement of the winding roller. The first slide rail has a clear linear extension characteristic, and the tight fit between the slider and the slide rail ensures that it runs strictly according to the preset trajectory, effectively preventing the winding roller from deviating or wobbling during horizontal movement. This ensures the accuracy of the door's movement trajectory during winding and unfolding, and improves the overall stability of the roller shutter door's operation.

[0011] Furthermore, the mounting base also includes a bracket and a mounting plate, the bracket being supported on the top of the door frame; the mounting plate is fixed on the bracket, and the first guide member is mounted on the mounting plate.

[0012] Based on the aforementioned technical means, the mounting bracket is set on the top of the door frame, constructing a stable basic support structure for the entire roller shutter system. The bracket effectively and evenly transmits various forces generated during the operation of the roller shutter, such as the tension during door winding and unfolding, and the thrust during horizontal adjustment of the winding rollers, to the door frame. Simultaneously, the mounting plate is fixed to the bracket, providing a stable mounting surface for the first guide component, ensuring that the first guide component will not deform or loosen when subjected to the dynamic load brought about by the movement of the slider, thereby greatly improving the stability and reliability of the overall roller shutter structure.

[0013] Furthermore, the bracket includes a crossbar and legs. The crossbar is fixed to the top of the door frame and extends horizontally. The legs are inclined and fixed at both ends to the crossbar and the door frame, respectively.

[0014] Based on the aforementioned technical means, the bracket adopts a combination design of crossbars and inclined legs, which greatly improves the stability of the overall structure. The crossbars are horizontally fixed to the top of the door frame, providing a stable foundation support surface for the entire bracket and effectively distributing the vertical load from the upper installed components (such as mounting plates, first guide components, etc.). The inclined legs are connected to the crossbars and the door frame at their respective ends, forming a stable triangular mechanical structure. Triangles have high stability and can withstand large external forces without deformation, thus significantly enhancing the load-bearing capacity of the bracket and ensuring that the bracket can stably support the upper components during the operation of the roller shutter door, without swaying or being damaged due to excessive force.

[0015] Furthermore, there are two mounting seats, which are respectively installed on opposite sides of the door frame; both ends of the take-up roller are connected to the two mounting seats respectively.

[0016] Based on the aforementioned technical means, this utility model provides two mounting seats, each installed on opposite sides of the door frame. The two ends of the winding roller are connected to the two mounting seats respectively. This layout ensures that the force borne by the winding roller during operation is evenly distributed across both sides of the door frame. During the winding and unwinding of the roller shutter, the winding roller is subjected to various forces, including the weight of the door, the driving force of the motor, and potential friction. The symmetrical support of the two mounting seats prevents structural displacement and instability caused by unilateral force, ensuring smooth horizontal rotation of the winding roller. This, in turn, guarantees the overall stability and reliability of the roller shutter, reducing malfunctions and safety hazards caused by uneven force distribution.

[0017] Furthermore, it also includes a drive unit, which is mounted on the mounting base and connected to the take-up roller to drive the take-up roller to rotate.

[0018] Based on the aforementioned technical means, the drive component is mounted on the mounting base and connected to the take-up roller, ensuring that the power generated by the drive component is accurately and efficiently transmitted to the take-up roller. During the operation of the roller shutter door, the torque output by the drive component is evenly applied to the take-up roller through the stable support of the mounting base, avoiding energy loss and instability during power transmission.

[0019] Furthermore, it also includes a door header panel, which is installed on the top of the door frame and is located on the side of the door body away from the take-up roller.

[0020] Based on the aforementioned technical means, the door header panel is installed at the top of the door frame and located on the side of the door body furthest from the winding roller, which can effectively balance the forces generated by the door body during operation. When the door body opens and closes, one side of the winding roller bears the weight of the door body and the dynamic force generated by the movement, while the presence of the door header panel can provide stable support on the other side, reducing the deformation of the door frame caused by uneven stress, thereby improving the structural stability and service life of the entire roller shutter door system.

[0021] Meanwhile, the top panel at the top of the door frame forms an additional protective layer, which can effectively prevent dust, rain, debris and other external objects from entering the gap between the door and the door frame, reducing the possibility of door malfunction or component damage caused by external factors.

[0022] Furthermore, it also includes a second guide member, which is disposed on the door frame and extends in a vertical direction; the side of the door body is connected to the second guide member.

[0023] Based on the aforementioned technical means, the second guide component is installed on the door frame and extends vertically, connecting to the side of the door body. This structure provides precise vertical guidance for the door body. During the opening and closing of the door, the second guide component effectively limits the horizontal swaying of the door body, ensuring that the door body always runs smoothly along the vertical direction. This avoids problems such as jamming and collisions caused by door body deviation, greatly improving the stability and reliability of door body operation.

[0024] Furthermore, it also includes a manual chain, which is connected to the drive unit.

[0025] Based on the aforementioned technical means, the manual chain is connected to the drive unit, providing a reliable emergency operation mechanism for the roller shutter door. When the drive unit malfunctions due to sudden events such as power failure, mechanical damage, or control system failure, the operator can pull the manual chain to directly act on the drive unit, thus manually opening or closing the door.

[0026] In summary, this utility model has the following beneficial effects:

[0027] The mounting base of this utility model's roller shutter door is at least partially movable in the horizontal direction, and the end of the winding roller is connected to the movable part of the mounting base, allowing the winding roller to move horizontally. During the door's winding process, as the winding thickness increases, the winding roller can move horizontally in a timely manner, avoiding friction and jamming between the door and the roller or other components due to space compression. This ensures the smoothness of the door's winding and unfolding actions, while preventing excessive compression and friction between the door and the roller and other components, thus reducing noise generation at its source.

[0031] The present invention will be further described in detail below with reference to the accompanying drawings.

[0032] To make the objectives, solutions, and advantages of this utility model clearer, the following detailed description of this utility model is provided in conjunction with the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0033] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, it will be apparent to those skilled in the art that these specific details are not necessary to implement the present invention. In other embodiments, well-known structures, circuits, materials, or methods are not specifically described in order to avoid obscuring the present invention.

They are only for the convenience of describing this utility model 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. Therefore, they should not be construed as limiting the scope of protection of this utility model.

[0035] The following is in conjunction with the appendix of this utility model. Figures 1-2 The embodiments of this utility model will be described in detail below.

[0036] Example 1:

[0037] like Figure 1As shown, a garage roller shutter door structure includes: a door frame 1 and a door body 2, the door body 2 being mounted on the door frame 1 and used to cover the door frame 1; a winding roller 3, the winding roller 3 being rotatably mounted on the top of the door frame 1, one side of the door body 2 being connected to the winding roller 3, the door body 2 being configured to be able to be wound onto or unwound from the winding roller 3 to cover the door frame 1; a mounting base 4, the mounting base 4 being fixed to the top of the door frame 1, and at least a portion of the mounting base 4 being movable in a horizontal direction; the end of the winding roller 3 being connected to the movable portion of the mounting base 4 so that the winding roller 3 can be moved in a horizontal direction.

[0038] In existing garage door rolling shutter technology, the rollers of the rolling shutter are fixed and cannot be moved. As the rolling shutter continues to roll onto the fixed rollers, the thickness of the roll increases, and the space between the rolling shutter and the rollers is gradually compressed, making it prone to jamming and causing the rolling action to be unsmooth. In this utility model, the mounting base 4 can be moved at least partially in the horizontal direction, and the end of the rolling roller 3 is connected to the movable part of the mounting base 4, allowing the rolling roller 3 to move horizontally. During the rolling process of the door body 2, as the thickness of the roll increases, the rolling roller 3 can move horizontally in a timely manner, avoiding friction and jamming between the door body 2 and the rollers or other components due to space compression. This ensures the smoothness of the rolling and unfolding action of the door body 2, and at the same time, prevents excessive compression and friction between the door body 2 and the rollers and other components, reducing noise generation at the source.

[0039] The specific usage process of the roller shutter door structure in this embodiment is as follows:

[0040] Closing process:

[0041] As the take-up roller 3 rotates, and since one side of the door body 2 is connected to the take-up roller 3, the door body 2 gradually unfolds from the winding state under the rotation of the take-up roller 3.

[0042] During the unfolding of the door 2, the take-up roller 3 will make minor horizontal adjustments based on the unfolding of the door 2 and the actual state of the door frame 1. Because the mounting base 4 can move at least partially in the horizontal direction, and the end of the take-up roller 3 is connected to the movable part of the mounting base 4, when the door 2 unfolds, if there is a slight deformation of the door frame 1 or a small error during installation that causes the door 2 to unfold unevenly, the take-up roller 3 will drive at least part of the mounting base 4 to move horizontally under the pulling force of the door 2, ensuring that the door 2 can unfold smoothly and without jamming or excessive friction with the door frame 1.

[0043] As the winding roller 3 continues to rotate and level, the door 2 gradually unfolds completely and covers the door frame 1. At this time, the roller shutter door is in a completely closed state, and the interior of the garage is effectively sealed and protected.

[0044] Opening process:

[0045] The take-up roller 3 rotates in the opposite direction. Under the action of the take-up roller 3, the door body 2 begins to be wound upward.

[0046] During the winding process of the door body 2, as the winding thickness increases, the winding roller 3 moves horizontally to a suitable position under the thrust between the door body 2 and the door frame 1 to avoid deformation.

[0047] After a period of winding and horizontal adjustment of the winding roller 3, the door 2 is fully wound up on the winding roller 3. At this time, the roller shutter door is in a fully open state, and users can easily drive their vehicles into or out of the garage.

[0048] It's easy to imagine that although the mounting base 4 is designed to move horizontally, it may become stuck due to dust accumulation and wear of parts during long-term use. When the rewind roller 3 is found to be moving horizontally unevenly, the user should stop using the roller shutter door and inspect and clean the mounting base 4.

[0049] In this preferred embodiment, to prevent excessive friction between the door body 2 and the door frame 1 during the winding process, which could damage the door body 2, an elastic buffer strip (not shown in the figure) is added to the edge where the door body 2 may come into contact with the door frame 1. The buffer strip can be made of a highly elastic and wear-resistant material, such as rubber or silicone. During the winding process, the buffer strip can first come into contact with the door body 2, absorbing part of the impact force through its own elastic deformation, thus reducing the direct collision and friction between the door body 2 and the door frame 1, and effectively protecting the surface of the door body 2 from damage.

[0050] like Figure 1 As shown, the mounting base 4 includes a first guide 41 and a movable member 42. The first guide 41 is mounted on the top of the door frame 1 and extends horizontally. The movable member 42 is movably mounted on the first guide 41 and is connected to the end of the take-up roller 3 so that the take-up roller 3 can move horizontally.

[0051] In this embodiment, the mounting base 4 consists of a first guide member 41 and a movable member 42. The first guide member 41 is securely mounted on the top of the door frame 1 and extends horizontally, providing a precise horizontal movement track for the movable member 42. The movable member 42 is movably mounted on the first guide member 41 and is tightly connected to the end of the winding roller 3. During the winding and unfolding process of the door body 2, as the winding thickness changes, the movable member 42 can move flexibly horizontally along the first guide member 41, driving the winding roller 3 to adjust its position synchronously. This effectively avoids the door body 2 getting stuck due to space compression, ensuring the smoothness of the winding and unfolding action of the door body 2 and greatly improving the user experience of the roller shutter door.

[0052] like Figure 1As shown, the first guide member 41 is the first slide rail, and the moving member 42 is the slider. The first slide rail and the slider are adapted to each other.

[0053] The first guide component 41 is designed as a first slide rail, and the moving component 42 is designed as a matching slider. This structure provides highly precise guidance for the horizontal movement of the winding roller 3. The first slide rail has a clear linear extension characteristic, and the tight fit between the slider and the slide rail can strictly follow the preset trajectory, effectively preventing the winding roller 3 from deviating or wobbling during horizontal movement. This ensures the accuracy of the movement trajectory of the door 2 during winding and unfolding, and improves the overall stability of the roller shutter door operation.

[0054] In this embodiment, the first slide rail is made of a high-strength material, possessing good rigidity and capable of withstanding various forces generated by the slider during movement. The surface of the first slide rail can be finely machined to achieve a smooth surface quality, while the slider can be made of a low-friction coefficient material or undergo special treatment to reduce friction between the two, making the slider move more smoothly on the slide rail and reducing energy loss.

[0055] like Figure 1 As shown, the mounting base 4 also includes a bracket 43 and a mounting plate 44. The bracket 43 is supported on the top of the door frame 1; the mounting plate 44 is fixed on the bracket 43, and the first guide member 41 is mounted on the mounting plate 44.

[0056] Mounting base 4, with bracket 43 supporting the top of door frame 1, provides a stable foundation support structure for the entire roller shutter system. Bracket 43 effectively and evenly transmits various forces generated during roller shutter operation, such as the tension during door body 2 winding and unfolding, and the thrust during horizontal adjustment of winding roller 3, to door frame 1. Simultaneously, mounting plate 44, fixed to bracket 43, provides a stable mounting surface for first guide member 41, ensuring that the first guide member 41 does not deform or loosen when subjected to dynamic loads from slider movement, thereby greatly improving the overall stability and reliability of the roller shutter system.

[0057] like Figure 2 As shown, the bracket 43 includes a crossbar 431 and a support leg 432. The crossbar 431 is fixed to the top of the door frame 1 and extends horizontally. The support leg 432 is inclined and its two ends are fixed to the crossbar 431 and the door frame 1 respectively.

[0058] The bracket 43 employs a combination design of a crossbar 431 and inclined legs 432, which greatly enhances the stability of the overall structure. The crossbar 431 is horizontally fixed to the top of the door frame 1, providing a stable foundation support surface for the entire bracket 43 and effectively distributing the vertical load from the upper mounting components (such as the mounting plate 44, the first guide member 41, etc.). The inclined legs 432 are connected to the crossbar 431 and the door frame 1 at both ends, forming a stable triangular mechanical structure. Triangles have high stability and can withstand large external forces without deformation, thus significantly enhancing the load-bearing capacity of the bracket 43. This ensures that during the operation of the roller shutter door, the bracket 43 can stably support the upper components without swaying or being damaged due to excessive force.

[0059] like Figure 1 As shown, there are two mounting bases 4, which are installed on opposite sides of the door frame 1 respectively; the two ends of the winding roller 3 are connected to the two mounting bases 4 respectively.

[0060] In this embodiment, two mounting bases 4 are installed on opposite sides of the door frame 1, and the two ends of the winding roller 3 are connected to the two mounting bases 4 respectively. This layout ensures that the force on the winding roller 3 during operation is evenly distributed on both sides of the door frame 1. When the roller shutter door is winding and unfolding, the winding roller 3 is subjected to various forces, including the gravity of the door body 2, the driving force of the motor, and possible friction. The symmetrical support of the two mounting bases 4 avoids structural displacement and instability caused by unilateral force, ensuring the smooth rotation of the winding roller 3 in the horizontal direction. This, in turn, guarantees the overall stability and reliability of the roller shutter door operation and reduces malfunctions and safety hazards caused by uneven force.

[0061] like Figure 1 As shown, the garage roller shutter door structure also includes a drive unit 5, which is mounted on the mounting base 4 and connected to the winding roller 3 to drive the winding roller 3 to rotate.

[0062] The drive unit 5 is mounted on the mounting base 4 and connected to the take-up roller 3, ensuring that the power generated by the drive unit 5 is accurately and efficiently transmitted to the take-up roller 3. During the operation of the roller shutter door, the torque output by the drive unit 5 is evenly applied to the take-up roller 3 through the stable support of the mounting base 4, avoiding energy loss and instability during power transmission.

[0063] In this embodiment, the drive unit 5 can be a DC motor. DC motors have good speed regulation performance, and the rotation speed of the winding roller 3 can be easily adjusted by changing the input voltage or current. During the opening and closing of the roller shutter door, operations such as rapid start and slow stop can be achieved according to actual needs, improving the convenience and safety of use. Moreover, the structure of a DC motor is relatively simple, and the control circuit is also relatively mature, making it easy to install and maintain, and effectively reducing the overall cost of the equipment.

[0064] Example 2:

[0065] like Figure 2 As shown, the garage roller shutter door structure of this embodiment also includes a door headboard 6, which is installed on the top of the door frame 1 and is located on the side of the door body 2 away from the winding roller 3.

[0066] The top panel 6 is installed on the top of the door frame 1 and located on the side of the door body 2 away from the winding roller 3. It can effectively balance the forces generated by the door body 2 during operation. When the door body 2 opens and closes, the winding roller 3 bears the weight of the door body 2 and the dynamic force generated by the movement on one side, while the top panel 6 can provide stable support on the other side, reducing the deformation of the door frame 1 caused by uneven force, thereby improving the structural stability and service life of the entire roller shutter door system.

[0067] Meanwhile, the door headboard 6 forms an additional protective layer at the top of the door frame 1, which can effectively block external dust, rainwater, debris and other objects from entering the gap between the door body 2 and the door frame 1, reducing the possibility of the door body 2 malfunctioning or its components being damaged due to external factors.

[0068] In this preferred embodiment, the door panel 6 can be made of polyethylene plastic as the core material and coated aluminum plate as the surface layer to improve corrosion resistance and aging resistance.

[0069] like Figure 1 and Figure 2 As shown, it also includes a second guide member 7, which is disposed on the door frame 1 and extends in the vertical direction; the side of the door body 2 is connected to the second guide member 7.

[0070] The second guide member 7 is mounted on the door frame 1 and extends vertically, connecting to the side of the door body 2. This structure provides precise vertical guidance for the door body 2. During the opening and closing of the door body 2, the second guide member 7 effectively limits the horizontal swaying of the door body 2, ensuring that the door body 2 always runs smoothly along the vertical direction. This avoids problems such as jamming and collisions caused by the door body 2 deviating, greatly improving the stability and reliability of the door body 2's operation.

[0071] In some embodiments, there are two second guide members 7, which are respectively arranged on opposite sides of the door frame 1. The vertical guiding effect of the two second guide members 7 makes the door body 2 more stable during operation and reduces the shaking of the door body 2.

[0072] like Figure 1 As shown, the garage roller shutter door structure also includes a manual chain 8, which is connected to the drive unit 5.

[0073] The manual chain 8 is connected to the drive unit 5, providing a reliable emergency operation mechanism for the roller shutter door. When the drive unit 5 fails to operate normally due to sudden situations such as power failure, mechanical damage, or control system malfunction, the operator can pull the manual chain 8 to directly act on the drive unit 5, thereby manually opening or closing the door.

[0074] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
