Description

Technical Field

[0001] This invention relates to the field of protective window technology, and more specifically, to a protective window. Background Technology

[0002] Protective windows are typically installed on the outside of glass windows in buildings to protect the windows during extreme weather events such as typhoons.

[0003] Existing protective windows typically consist of multiple sequentially connected protective units. One of these units, located at one end, is a fixed protective unit that is fixedly connected to the window frame. The remaining protective units are slidably mounted on the window frame to move closer to or further away from the fixed protective unit, and adjacent protective units are hinged together. The protective window has a folded state and an unfolded state. When the window is unfolded, the multiple protective units block the glass window. When the window is folded, the multiple protective units slide sequentially toward the side closer to the fixed protective unit and stack with adjacent protective units until they slide to the position of the fixed protective unit.

[0004] However, when existing protective windows are folded, multiple protective units are usually stacked on one side of the glass window, which can easily obstruct the view through the glass window, resulting in a poor user experience. Summary of the Invention

[0005] This invention provides a protective window to solve the problem in the prior art where protective windows obstruct the view when folded, resulting in poor comfort.

[0006] This invention provides a protective window, comprising: a window frame; multiple folding sections arranged in a stacked manner, each folding section having a connecting end and an abutting end arranged opposite each other along its length, the width of the folding section gradually increasing along the direction from the connecting end to the abutting end, each folding section having a first side and a second side arranged opposite each other along its width; the multiple folding sections include a head folding section and an end folding section, the first side of the head folding section being hinged to the inner wall of the window frame, the head folding section having a closed limit position and an open limit position arranged opposite each other, when the head folding section is closed... In the extreme position, the second side of the first folding part is inside the window frame; when the first folding part is in the open limit position, the second side of the first folding part is outside the window frame. A connecting shaft passes through the connecting end of multiple folding parts. The protective window has a fully closed state and a fully open state arranged opposite to each other. When the protective window is in the fully closed state, the end faces of the abutting ends of multiple folding parts and the second side of the end folding part abut against the inner wall of the window frame to seal the window frame. When the protective window is in the fully open state, multiple folding parts are in the folded state and the second side of the first folding part is in the open limit position.

[0007] Furthermore, the multiple folds also include multiple middle folds, which are located between the first fold and the last fold.

[0008] Furthermore, the protective window also includes: a first linkage structure, disposed between two adjacent folding parts, so that multiple folding parts unfold sequentially from the end folding part to the beginning folding part; and a second linkage structure, disposed between two adjacent folding parts, so that multiple folding parts fold sequentially from the end folding part to the beginning folding part.

[0009] Furthermore, the first side of the end fold and the plurality of middle folds bends toward the beginning fold and forms a first bending structure; the second side of the beginning fold and the plurality of middle folds bends toward the end fold and forms a second bending structure; the first bending structure and the second bending structure between adjacent folds can engage with each other and form a first linkage structure.

[0010] Furthermore, the first side of the multiple middle folds is provided with a protrusion structure, which is positioned toward the end fold. The first side of the upper fold and the protrusion structure of the lower fold can abut against each other to form a second linkage structure.

[0011] Furthermore, the protective window also includes a positioning part, which is located on one side of the first folding part near the last folding part, and the positioning part is respectively positioned and engaged with multiple protrusion structures.

[0012] Furthermore, the positioning part is provided with multiple positioning grooves, and the positioning grooves are provided in a one-to-one correspondence with the protrusion structure, and the positioning grooves and protrusion structures are positioned and engaged.

[0013] Furthermore, the end fold is fixedly connected to the connecting shaft, and the remaining folds can rotate relative to the connecting shaft. The protective window also includes a first driving member, which is disposed on the connecting shaft and drivenly connected to the connecting shaft to drive the end fold to rotate through the connecting shaft.

[0014] Furthermore, the protective window also includes: a second driving member disposed on the window frame; a linkage structure including a plurality of linkages hinged to each other, the linkage structure having a first end and a second end disposed opposite to each other, the second driving member being driven connected to the first end of the linkage structure, and the second end of the linkage structure being driven connected to the first end folding part, so that the first end folding part rotates between the closed limit position and the open limit position.

[0015] Furthermore, the window frame is a rectangular frame structure, including a top frame, a first side frame, a bottom frame, and a second side frame arranged sequentially. The first side of the first folding part is hinged to the first side frame. The multiple folding parts include a first folding unit and a second folding unit arranged sequentially from the first folding part to the end folding part. The abutting end of the first folding unit abuts against the bottom frame, and the abutting end of the second folding unit abuts against the second side frame. The protective window also includes a first limiting structure, which is disposed between the second folding unit and the second side frame. When the protective window is in the fully closed state, the first limiting structure can limit the position of the first folding unit relative to the window frame in the thickness direction of the window frame.

[0016] Furthermore, the first limiting structure includes a first limiting groove, which has a sealing end and an opening end that are arranged opposite to each other along the direction from the top frame to the bottom frame. The opening end is set towards the bottom frame. When the protective window is in the fully closed state, the abutting end of the second folding unit is embedded in the first limiting groove and cooperates with the first limiting groove for limiting.

[0017] Furthermore, the protective window also includes a second limiting structure, which is disposed between the bottom frame and the first folding unit. The second limiting structure is used to limit the position of the first folding unit and the bottom frame in the thickness direction of the bottom frame.

[0018] Furthermore, the second limiting structure includes a plurality of second limiting grooves disposed on the outer side wall of the bottom frame. The plurality of second limiting grooves are distributed in a stepped manner along the extension direction of the bottom frame, and the second limiting grooves are mutually limiting and cooperating with the abutting end of the first folding unit.

[0019] By applying the technical solution of this invention, the obstruction of the protective window's view by the window can be minimized when it is not needed, thus improving the user experience. Specifically, in extreme weather conditions such as strong winds, the protective window is fully closed, meaning the first folding part is at its closed limit position, and the end faces of the abutting ends of multiple folding parts and the second side of the last folding part abut against and seal the inner wall of the window frame. When the protective window is not needed, all multiple folding parts are folded, and the second side of the first folding part is at its open limit position, allowing the folding parts to rotate towards the outside of the window to reduce obstruction of the view. In conventional solutions, the protective units of the protective window are slidably mounted on the window frame, and adjacent protective units are hinged together. When the protective window is not needed, multiple protective units accumulate on one side of the window frame, severely obstructing the corresponding end of the window, resulting in a poor user experience. Compared with traditional technical solutions, the design of this application allows the entire structure to rotate outwards towards the glass window after all the folding parts are folded, thereby reducing or avoiding obstruction of the window view and ensuring the user's experience.

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] like Figures 1 to 10 As shown, this embodiment of the invention provides a protective window, which includes a window frame 10, multiple folding sections, and a connecting shaft 30. The multiple folding sections are stacked sequentially, each folding section having a connecting end and an abutting end arranged opposite each other along its length. The width of the folding section gradually increases along the direction from the connecting end to the abutting end. Each folding section has a first side and a second side arranged opposite each other along its width. The multiple folding sections include a first-end folding section 21 and a second-end folding section 22. The first side of the first-end folding section 21 is hinged to the inner wall of the window frame 10. The first-end folding section 21 has a closed limit position and an open limit position arranged opposite each other. When the first-end folding section 21 is in the closed limit position, the second side of the first-end folding section 21 is located inside the window frame 10; when the first-end folding section 21 is in the open limit position, the second side of the first-end folding section 21 is located outside the window frame 10. A connecting shaft 30 passes through the connecting ends of multiple folding parts. The protective window has a fully closed state and a fully open state, respectively. When the protective window is fully closed, the end faces of the abutting ends of the multiple folding parts and the second side of the end folding part 22 abut against the inner wall of the window frame 10 to seal the window frame 10. When the protective window is fully open, the multiple folding parts are folded, and the second side of the first folding part 21 is at its maximum opening position. Specifically, during assembly, the window frame 10 is assembled to the exterior wall of the building and located outside the glass window. When the protective window is fully open, the multiple folding parts rotate towards the outside of the glass window.

[0043] By applying the technical solution of this invention, the obstruction of the protective window's view by the glass window can be minimized when it is not needed, thereby improving the user experience. Specifically, in extreme weather conditions such as strong winds, the protective window is fully closed, meaning the first folding part 21 is at its closed limit position, and the end faces of the abutting ends of multiple folding parts and the second side of the last folding part 22 abut against and seal the inner wall of the window frame 10. When the protective window is not needed, all multiple folding parts are folded, and the second side of the first folding part 21 is at its open limit position, allowing the multiple folding parts in the folded state to rotate towards the outside of the glass window, thereby reducing obstruction of the view. In conventional technical solutions, the protective units of the protective window are slidably mounted on the window frame, and adjacent protective units are hinged to each other. When the protective window is not needed, multiple protective units accumulate on one side of the window frame, severely obstructing the corresponding end of the glass window, resulting in a poor user experience. Compared with traditional technical solutions, the design of this application allows the entire structure to rotate outwards towards the glass window after all the folding parts are folded, thereby reducing or avoiding obstruction of the window view and ensuring the user's experience.

[0044] Furthermore, the multiple folding sections also include multiple middle folding sections, located between the first folding section 21 and the last folding section 22. In this design, the distances between the first and second sides of the multiple middle folding sections, the distances between the first and second sides of the first folding section 21, and the distances between the first and second sides of the last folding section 22 are similar. The arrangement of multiple middle folding sections can correspondingly reduce the distance between the first and second sides of each folding section. When the first folding section 21 is in its open limit position, it ensures that the distance between the second sides of the multiple folding sections and the window frame 10 is sufficiently small, ensuring the stability of the multiple folding sections. This design does not limit the specific number of middle folding sections; in this embodiment, the number of middle folding sections is four.

[0045] like Figure 9 and Figure 10 As shown, the protective window further includes a first linkage structure 41. The first linkage structure 41 is disposed between two adjacent folding sections, allowing the multiple folding sections to unfold sequentially from the end folding section 22 to the first folding section 21. The first linkage structure 41 ensures that the multiple folding sections unfold sequentially from the end folding section 22 to the first folding section 21, guaranteeing smooth opening of the protective window.

[0046] Specifically, the first side of the end fold 22 and the plurality of middle folds bends toward the beginning fold 21 to form a first bending structure 411; the second side of the beginning fold 21 and the plurality of middle folds bends toward the end fold 22 to form a second bending structure 412; the first bending structure 411 and the second bending structure 412 between adjacent folds can engage with each other to form a first linkage structure 41. In this embodiment, when the protective window is fully closed, the first folding part 21 is located outside the end folding part 22, that is, the distance between the first folding part 21 and the glass window is greater than the distance between the end folding part 22 and the glass window; the first side of the end folding part 22 and the multiple middle folding parts bends outward to form a first bending structure 411; the second side of the first folding part 21 and the multiple middle folding parts bends inward to form a second bending structure 412; when the multiple folding parts are unfolded, the first bending structure 411 and the second bending structure 412 between two adjacent folding parts are generally hooked together. In this embodiment, the six folds are arranged sequentially from the first fold 21 to the last fold 22: first fold, second fold, third fold, fourth fold, fifth fold, and sixth fold. When the six folds switch from a folded state to an unfolded state, the sixth fold rotates first until the first bending structure 411 of the sixth fold and the second bending structure 412 of the fifth fold engage. Then, the sixth fold drives the fifth fold to rotate around the connecting shaft 30, and so on, until the first bending structure 411 of the second fold and the second bending structure 412 of the first fold engage. The first bending structure 411 and the second bending structure 412 are simple in structure and are formed by bending the sides of each fold, possessing sufficient length to ensure the stability of the linkage between adjacent folds.

[0047] Furthermore, the protective window also includes a second linkage structure, which is disposed between two adjacent folding sections, so that the multiple folding sections fold sequentially from the end folding section 22 to the beginning folding section 21. The second linkage structure ensures the smoothness of the folding process of the multiple folding sections.

[0048] Specifically, a protrusion structure 42 is provided on the first side of each of the multiple middle folds, and the protrusion structure 42 is positioned towards the end fold 22. The first side of the upper fold and the protrusion structure 42 of the lower fold between adjacent folds can abut against each other to form a second linkage structure. In this embodiment, the inner side of the first side of the second, third, fourth, and fifth folds is provided with a protrusion structure 42. When the multiple folds switch from an unfolded state to a folded state, the sixth fold rotates towards the first fold until the first side of the sixth fold abuts against the protrusion structure 42 on the first side of the fifth fold. The sixth and fifth folds rotate and fold synchronously, and so on, until the first side of the third fold abuts against the protrusion structure 42 on the first side of the second fold, and the second fold rotates to the folded state. The protrusion structure 42 is simple in structure, and by setting the protrusion structure 42 on the first side of the middle folding part, it can ensure that the two adjacent folding parts rotate synchronously after they overlap, thus ensuring the smoothness of the folding part folding.

[0049] Furthermore, the protective window also includes a positioning part 43, which is disposed on the side of the first folding part 21 near the end folding part 22. The positioning part 43 is positioned and engaged with multiple protrusion structures 42. The positioning part 43 is provided so that it can be positioned and engaged with multiple protrusion structures 42 to ensure the stability of multiple folding parts after they are folded and reduce the possibility of multiple folding parts shaking.

[0050] Furthermore, the positioning part 43 is provided with a plurality of positioning grooves 431, and the positioning grooves 431 are provided one-to-one with the protrusion structures 42, and the positioning grooves 431 and the protrusion structures 42 are positioned and engaged. In this embodiment, the positioning part 43 is provided on the inner side of the first end folding part 21 and is provided close to the first side; the positioning part 43 has a mating side, which is perpendicular to the plate surface of the first end folding part 21 and is provided facing the second side of the first end folding part 21. The mating side has a connecting side and a free side that are provided opposite to each other. The connecting side is connected to the plate surface of the first end folding part 21. The plurality of positioning grooves 431 are distributed in a stepped manner along the extension direction of the connecting side, and the distance between the plurality of positioning grooves 431 and the connecting side gradually increases along the direction from the abutment end to the connecting end of the first end folding part 21. The end of the positioning groove 431 closest to the abutment end extends to the side of the first end folding part 21 to form an opening. This configuration ensures that the four protrusion structures 42 are embedded in the corresponding positioning slots 431 in a one-to-one correspondence, avoiding mutual interference and ensuring the stability of the positioning of the four central folding parts.

[0051] like Figures 1 to 8As shown, further, the end folding portion 22 is fixedly connected to the connecting shaft 30, while the other folding portions can rotate relative to the connecting shaft 30. The protective window also includes a first driving member 301, which is disposed on and drivenly connected to the connecting shaft 30 to drive the end folding portion 22 to rotate via the connecting shaft 30. In this embodiment, the first driving member 301 is a first motor, and the second to fifth folding portions are all interference-fitted with the connecting shaft 30. The above configuration ensures the convenience of opening and closing the window and guarantees the stability of the window when it is fully closed.

[0052] Furthermore, the protective window also includes a second driving member 51 and a connecting rod structure 52, wherein the second driving member 51 is disposed on the window frame 10. The connecting rod structure 52 includes a plurality of connecting rods hinged to each other, and the connecting rod structure 52 has a first end and a second end disposed opposite to each other. The second driving member 51 is driven connected to the first end of the connecting rod structure 52, and the second end of the connecting rod structure 52 is driven connected to the first end folding part 21, so that the first end folding part 21 rotates between the closed limit position and the open limit position. In this embodiment, the second driving member 51 is a second motor, and the connecting rod structure 52 includes a first connecting rod, a second connecting rod, and a third connecting rod that are hinged sequentially, wherein the output shaft of the second motor is driven connected to the end of the first connecting rod away from the second connecting rod, and the end of the third connecting rod away from the second connecting rod is fixedly connected to the inner sidewall of the first end folding part 21. This arrangement can ensure the stability and smoothness of the rotation process of the first end folding part 21.

[0053] like Figure 4As shown, specifically, the window frame 10 is a rectangular frame structure, including a top frame 11, a first side frame 12, a bottom frame 13, and a second side frame 14 arranged sequentially. The first side of the initial folding portion 21 is hinged to the first side frame 12. Multiple folding portions include a first folding unit and a second folding unit arranged sequentially from the initial folding portion 21 to the final folding portion 22. The abutting end of each first folding unit abuts against the bottom frame 13; the abutting end of each second folding unit abuts against the second side frame 14. The protective window also includes a first limiting structure 60, which is disposed between the second folding unit and the second side frame 14. When the protective window is fully closed, the first limiting structure 60 can restrict the position of the first folding unit relative to the window frame 10 in the thickness direction of the window frame 10. The first limiting structure 60 ensures the stability of the second folding unit when it is in the unfolded state, preventing or reducing the possibility of the second folding unit reversing towards the inside or outside of the window frame 10, and ensuring the stability of the protective window when it is closed. In this embodiment, the connecting ends of the six folding parts are roughly circular to ensure smooth rotation. The first, second, fourth, fifth, and sixth folding parts are roughly trapezoidal in shape. The abutting ends of the first and second folding parts abut against the bottom frame 13 of the window frame. The abutting ends of the fourth, fifth, and sixth folding parts abut against the second side frame 14 of the window frame. The third folding part has a bottom abutting edge and a side abutting edge connected in sequence, which abut against the bottom frame 13 and the second side frame 14, respectively. That is, the third folding part is diagonally aligned with the window frame. The first, second, and third folding parts form a first folding unit, and the fourth, fifth, and sixth folding parts form a second folding unit.

[0054] Specifically, the first limiting structure 60 includes a first limiting groove, which has a sealing end and an opening end arranged opposite to each other along the direction from the top frame 11 to the bottom frame 13. The opening end faces the bottom frame 13, and the length of the first limiting groove is less than the length of the second side frame 14. When the protective window is fully closed, the abutting end of the second folding unit is embedded in the first limiting groove and engages with the first limiting groove for limiting. When the window is closed, the first driving member 301 is activated. The first driving member 301 drives the sixth folding part to rotate through the connecting shaft 30. Under the action of multiple sets of first linkage structures, the fifth folding part to the second folding part unfolds in sequence. Since the third folding part in this solution is set on the diagonal of the window frame 10, and the third folding part is the longest, all folding parts can only seal the window frame 10 after all folding parts are unfolded. Therefore, after all folding parts are unfolded, the second driving member 51 is activated. The second driving member 51 drives the first folding part to rotate until the third folding part is partially embedded in the window frame. Within frame 10, the second folding unit abuts against the outer wall of the first limiting groove; the first driving member 301 drives the sixth folding part to rotate via the connecting shaft 30 to fold the sixth folding part until the fourth folding part is in a folded state, and the second driving member 51 continues to drive the first folding part to rotate until the third folding part is completely embedded in the window frame 10, and the second folding unit is located below the first limiting groove; then, the first driving member 301 drives the sixth folding part to rotate, and the rotation of the sixth folding part drives the fifth folding part to rotate until the abutting end of the sixth folding part and the abutting end of the fifth folding part are sequentially inserted into the first limiting groove.

[0055] Furthermore, the protective window also includes a second limiting structure 70, which is disposed between the bottom frame 13 and the first folding unit. The second limiting structure 70 is used to limit the position of the first folding unit and the bottom frame 13 in the thickness direction of the bottom frame 13. The setting of the second limiting structure 70 can further ensure the stability of the first folding unit when the protective window is in the fully closed state.

[0056] Specifically, the second limiting structure 70 includes a plurality of second limiting grooves disposed on the outer side wall of the bottom frame 13. The plurality of second limiting grooves are distributed in a stepped manner along the extension direction of the bottom frame 13, and the second limiting grooves are respectively limited and engaged with the abutting end of the first folding unit. The setting of the second limiting grooves is simple in structure and facilitates the abutting and limiting of the folded part of the first folding unit.
