[0045] In order for those skilled in the art to better understand the technical solutions in the present specification, the technical solutions in the present specification will be described clearly and completely in the following with reference to the drawings in the present specification. Obviously, the described embodiments are only some of the embodiments of the present specification, not all. Based on the embodiments in the present specification, all other embodiments obtained by those skilled in the art without creative labor should belong to the scope of protection of the present specification.

[0046] In the embodiments of the present application, the terms "first", "second" and the like are used to distinguish different elements, but do not indicate the spatial arrangement or time sequence of the elements, and the elements should not be limited by these terms. The term "and / or" includes any one and all combinations of the associated listed terms. The terms "comprise", "include", "have" and the like mean the presence of the stated features, elements, components or assemblies, but do not exclude the presence or addition of one or more other features, elements, components or assemblies.

[0047] In the embodiments of the present application, the singular form "one", "the" and the like can include the plural form, and should be understood broadly as "one kind" or "one type" rather than the meaning of "one"; in addition, the term "said" should be understood as including both the singular form and the plural form, unless the context clearly indicates otherwise; in addition, the term "according to" should be understood as "at least partially according to", and the term "based on" should be understood as "at least partially based on", unless the context clearly indicates otherwise; in addition, the meaning of the term "a plurality of" is two or more, unless otherwise specified.

[0048] In the embodiments of the present application, the use of adjectival or adverbial modifiers "horizontal" and "vertical", "upper" and "lower", "longitudinal" and "transverse", "clockwise" and "counterclockwise", "front" and "back", "left" and "right", "top" and "bottom", "inner" and "outer" is only for the convenience of relative reference between the two groups of terms, and does not describe any specific directional limitation of the modified terms.

[0049] The embodiments of the present application provide a foldable and overturnable window structure, which comprises a frame, a first window body, a second window body and an overturning driver. The first window body is overturnably connected with the frame, and the second window body is slidably connected with the first window body. The second window body and the first window body are overlapped or unfolded by sliding the second window body along the first window body. The overturning driver is connected with the frame and the first window body, and is used to drive the overlapped first window body and second window body to overturn relative to the frame.

[0050] The second window body of the present application is slidably connected with the first window body, rather than being slidably connected with the frame. Therefore, when the second window body is slid to overlap with the first window body, the second window body can overturn together with the first window body relative to the frame, so that a larger window opening space can be obtained.

[0051] It should be noted that the term "window structure" in the present application should be understood broadly, which refers to any openable and closable structure, including but not limited to windows, doors and the like.

[0052] The embodiments of the present application will be described below with reference to the accompanying drawings.

[0053] As Figure 1 and Figure 2As shown, the foldable and flip window structure comprises a frame 1, a first window body 2, a second window body 3 and a flip driver 4, the inner space of the frame 1 can be covered by the first window body 2 and the second window body 3, by sliding the second window body 3, a part of the inner space can be opened, by flipping the first window body 2 and the second window body 3 by using the flip driver 4, the whole inner space can be opened.

[0054] Figure 1 and Figure 2 As shown, the frame 1 is generally a square frame 1, the frame 1 comprises two opposite and spaced longitudinal support rods 101 and a transverse support rod 102, the two longitudinal support rods 101 are arranged along the vertical direction respectively, the transverse support rod 102 is arranged along the horizontal direction, the opposite ends of the transverse support rod 102 are connected with the top ends of the two longitudinal support rods 101 respectively.

[0055] The material of the frame 1 can be steel, which has high structural strength and can stably support the two window bodies.

[0056] As shown, Figure 1 and Figure 2 As shown, the first window body 2 comprises a first transparent plate 201 and a first window frame surrounded by two first longitudinal rods 202 and two first transverse rods 203, the first window frame is fixed to the periphery of the first transparent plate 201 to support the first transparent plate 201.

[0057] Figure 1 and Figure 2 As shown, the first transparent plate 201 is a square plate, the material of which can be glass, the first window frame is fixed to the inner side of the first transparent plate 201, on the one hand, the outer side of the first transparent plate 201 facing outward is smooth without protruding structure, on the other hand, it is convenient to set the second window body 3 on the outer side of the first transparent plate 201.

[0058] As shown, Figure 1 , Figure 2 and Figure 15 As shown, the first transverse rod 203 at the upper side of the first window body 2 is provided with a plurality of hinges 204, the plurality of hinges 204 are arranged at intervals along the first transverse rod 203, the plurality of hinges 204 are connected with the transverse support rod 102 of the frame 1, so that the first window body 2 can be flipped relative to the frame 1.

[0059] As shown, Figure 1 , Figure 2 , Figure 10 and Figure 18 As shown, the second window body 3 comprises a second transparent plate 301 and a second window frame surrounded by two second longitudinal rods 302 and two second transverse rods 303, the second window frame is fixed to the periphery of the second transparent plate 301 to support the second transparent plate 301.

[0060] Figure 1 andFigure 2 The second transparent plate 301 is a square plate, which can be made of glass. The second window frame is fixed to the inner side of the second transparent plate 301, so that the outer side of the second transparent plate 301 is smooth without protruding structure, and the first window 2 can be connected to the second window 3 conveniently.

[0061] In some embodiments, as shown in Figure 15 The second window 3 is connected to the first window 2 through the slide rail 5. Unlike the prior art, the slide rail 5 is arranged between the first window 2 and the second window 3, and the slide rail 5 is independent of the frame 1, so that the slide rail 5 does not limit the overturning of the first window 2 and the second window 3.

[0062] In Figure 15 the example, the first window 2 and the second window 3 are respectively provided with a group of slide rails 5. Each group of slide rails 5 includes a first guide rail 501 fixed to the longitudinal side edge of the first window 2, a second guide rail 502 fixed to the longitudinal side edge of the second window 3, and a telescopic slide rail 504 arranged between the first guide rail 501 and the second guide rail 502. The first guide rail 501, the second guide rail 502, and the telescopic slide rail 504 all extend along the longitudinal direction of the first window 2 or the second window 3.

[0063] As shown in Figure 15 the first guide rail 501 can be fixed to the inner side of the first transparent plate 201 and arranged side by side with the first longitudinal rod 202. The first guide rail 501 can be fixed to the side of the first longitudinal rod 202, and a guide groove 503 is formed in the first guide rail 501.

[0064] As shown in Figure 15 and Figure 22 the second guide rail 502 can be fixed to the inner side of the second longitudinal rod 302. The second guide rail 502 includes a first side plate 5021, a second side plate 5022, and a connecting plate 5023 connected between the first side plate 5021 and the second side plate 5022. The first side plate 5021 and the second side plate 5022 are substantially parallel, so that the cross section of the second guide rail 502 is substantially U-shaped. The first side plate 5021 is located on the outer side of the first transparent plate 201 and is fixedly connected with the second longitudinal rod 302. The second side plate 5022 is located on the inner side of the first transparent plate 201 and is inserted into the guide groove 503, so that the second guide rail 502 and the first guide rail 501 are inserted and fitted.

[0065] As shown in Figure 23 and Figure 24As shown, the telescopic slide rail 504 is located in the guide groove 503, and the telescopic slide rail 504 comprises a plurality of sliding sections which are sequentially connected in sliding manner, so that the plurality of sliding sections can slide relative to each other, thereby realizing the telescopic extension and contraction of the telescopic slide rail 504. The innermost sliding section is fixedly connected with the first guide rail 501, and the outermost sliding section is fixedly connected with the second guide rail 502, so that the second guide rail 502 can slide along the guide groove 503 relative to the first guide rail 501, and the telescopic slide rail 504 can extend and contract with the sliding of the second guide rail 502, thereby realizing the sliding connection of the first window body 2 and the second window body 3. By arranging two groups of slide rails 5, the sliding of the second window body 3 is more stable.

[0066] By arranging two groups of slide rails, the window structure of the present application can have a closed state and different open states.

[0067] Figure 1 and Figure 2 is a schematic view of the window structure in the closed state, i.e., the second window body 3 does not slide towards the first window body 2, and the first window body 2 and the second window body 3 are in the unfolded state.

[0068] Figure 3 and Figure 4 is a schematic view of the window structure in the first sliding open state, i.e., the second window body 3 slides towards the first window body 2 by a first distance, and the first window body 2 and the second window body 3 are in the partially overlapped state.

[0069] Figure 5 and Figure 6 is a schematic view of the window structure in the second sliding open state, i.e., the second window body 3 slides towards the first window body 2 by a second distance, and the first window body 2 and the second window body 3 are in the partially overlapped state, the second distance being greater than the first distance, and the opening space of the third open state being greater than the opening space of the second open state.

[0070] Figure 7 and Figure 8 is a schematic view of the window structure in the third sliding open state, i.e., the second window body 3 slides towards the first window body 2 by a third distance, and the first window body 2 and the second window body 3 are in the completely overlapped state, the third distance being greater than the second distance, the third distance being substantially equal to the longitudinal width of the second window body 3, which is also the maximum sliding stroke of the second window body 3, and the opening space of the third open state being greater than the opening space of the second open state.

[0071] When the second window body 3 slides to different positions, additional auxiliary positioning means can be used to keep the second window body 3 at the corresponding position, such as the operator can hold the second window body 3 by hand to prevent the second window body 3 from sliding down.

[0072] In order to keep the second window body 3 at any position in the sliding stroke without the aid of external force, in some embodiments, as Figure 2 ,Figure 4 , Figure 6 , Figure 8 As shown, the window structure of this application also includes an elastic component 6 for providing an upward pulling force to the second window 3. The elastic component 6 is connected between the first window 2 and the second window 3. The upward pulling force of the elastic component 6 on the second window 3 is approximately equal to the weight of the second window 3. Therefore, this pulling force can hold the second window 3 at any position within its sliding stroke, such as holding the second window 3 at... Figure 4 or Figure 6 The position shown does not require external force to prevent the second window 3 from slipping.

[0073] In addition, since the tension of the elastic component 6 basically offsets the gravity of the second window 3, the operator only needs to apply a small amount of force to easily slide the second window 3 upward, making the operation effortless and convenient.

[0074] Alternatively, for example Figure 2 , Figure 4 , Figure 6 and Figure 8 As shown, the elastic component 6 includes multiple coil springs 601, and multiple coil spring shafts 602 are provided on the first window 2. One end of each coil spring 601 is wound around the multiple coil spring shafts 602, and the other end of each coil spring 601 is connected to the second window 3.

[0075] exist Figure 15 and Figure 18 In the example, multiple coil spring shafts 602 are located at the lower end of the first vertical bar 202 of the first window frame. The multiple coil spring shafts 602 are arranged at intervals from top to bottom. The multiple coil spring shafts 602 are covered by a housing 603. The upper ends of multiple coil springs 601 are respectively wound around the multiple coil spring shafts 602. The lower ends of multiple coil springs 601 extend out of the housing 603 and are connected to the second horizontal bar 303 below the second window frame.

[0076] Optionally, the window structure includes two sets of elastic components 6, which are respectively disposed on opposite sides of the first window 2 and the second window 3 to provide symmetrical tension from both sides of the second window 3. The sum of the tension of the two sets of elastic components 6 on the second window 3 is approximately equal to the weight of the second window 3.

[0077] To prevent the second window 3 from flipping outwards due to improper force applied during the operator's upward sliding process, in some embodiments, such as... Figure 4 , Figure 6 , Figure 15 , Figure 16 and Figure 17 As shown, the opposite sides of the second window 3 are magnetically attached to the frame 1 so that the second window 3 can slide close to the frame 1 along the side edge of the first window 2 and provide friction for the second window 3.

[0078] In this embodiment, the sum of the frictional force and the elastic component 6 of the upward pulling force on the second window body 3 is substantially equal to the gravity of the second window body 3, so that the second window body 3 can hover at any position within its sliding stroke without the need of external force to prevent the second window body 3 from falling.

[0079] Exemplarily, as shown in Figure 15 , Figure 16 , Figure 17 and Figure 19 , the window structure comprises a magnetic positioning component 7, which comprises a plurality of magnets 701 arranged on the second window body 3, and the plurality of magnets 701 are in contact with and attracted to the frame 1 made of metal, so that the second window body 3 is tightly attached to the frame 1 under the action of the magnetic force, thereby limiting the outward turning of the second window body 3 by the magnetic force and providing frictional damping for the second window body 3.

[0080] For example, the magnetic positioning component 7 is arranged on the sliding rail 5, so that the sliding rail 5 is attached to the frame 1 by magnetic attraction, thereby enabling the second window body 3 to be attached to the frame 1 and to slide tightly against the frame 1. However, the present application is not limited thereto, and the magnetic positioning component 7 can also be arranged on the frame 1, and the sliding rail 5 is made of metal, so that the sliding rail 5 can also be attached to the frame 1 by magnetic attraction.

[0081] Optionally, the plurality of magnets 701 are fixed on the second side plate 5022 of the second guide rail 502, and the plurality of magnets 701 are located outside the guide groove 503 of the first guide rail 501 and are spaced apart along the longitudinal direction of the second window body 3 on the second side plate 5022, so as to increase the range of magnetic force action and increase the magnetic force between the second window body 3 and the frame 1.

[0082] Optionally, the plurality of magnets 701 are spaced apart along the entire longitudinal width of the second window body 3, so that the entire side edge of the second window body 3 is tightly attached to the frame 1.

[0083] Although the window structure can be partially opened by sliding the second window body 3 towards the first window body 2, in some cases it can still not meet the space requirement. In order to provide a larger opening space, it is necessary to turn over the first window body 2 and the second window body 3 as a whole, so when the second window body 3 is slid to be overlapped with the first window body 2 (as shown in Figure 7 ), the first window body 2 and the second window body 3 can be driven to turn over as a whole by the turning driver 4, thereby opening the entire inside space of the frame 1.

[0084] Figure 8An installation example of the turnover driver 4 is provided, two turnover drivers 4 are respectively arranged at opposite sides of the first window body 2, the turnover driver 4 is a gas spring, one end of the gas spring is hinged to the longitudinal support rod 101 of the frame 1, the other end of the gas spring is hinged to the first longitudinal rod 202 of the first window body 2, thus the gas spring can drive the first window body 2 and the second window body 3 to turn over or reset by stretching and retracting.

[0085] Figure 7 And Figure 8 It is a schematic view of the window structure in the non-overturning state, that is, the piston rod 401 of the gas spring is not extended, the second window body 3 is close to the frame 1, and the first window body 2 and the second window body 3 remain in the vertical state.

[0086] Figure 9 And Figure 10 It is a schematic view of the window structure in the first overturning open state, that is, the piston rod 401 of the gas spring is extended by a first length, and drives the first window body 2 and the second window body 3 to overturn by a first angle relative to the frame 1. For example, the first angle is 30° or 45°.

[0087] Figure 11 And Figure 12 It is a schematic view of the window structure in the second overturning open state, that is, the piston rod 401 of the gas spring is extended by a second length, and drives the first window body 2 and the second window body 3 to overturn by a second angle relative to the frame 1, the second length is greater than the first length, and the second angle is greater than the first angle. For example, the second angle is 60°.

[0088] Figure 13 And Figure 14 It is a schematic view of the window structure in the third overturning open state, that is, the piston rod 401 of the gas spring is extended by a third length, and drives the first window body 2 and the second window body 3 to overturn by a third angle relative to the frame 1, the third length is greater than the second length, and the third angle is greater than the second angle. For example, the second angle is 90°.

[0089] When the first window body 2 and the second window body 3 are turned to different positions, the gas spring can keep the first window body 2 and the second window body 3 at the corresponding positions without worrying about the automatic overturning and resetting of the first window body 2 and the second window body 3. The piston rod 401 of the gas spring drives the first window body 2 and the second window body 3 to reset by retracting.

[0090] The gas spring is only an example of the turnover driver 4, which does not limit the scope of the present application, and the turnover driver 4 can also be other extendable driving devices.

[0091] In order to keep the second window body 3 and the first window body 2 in the stacked state and prevent the second window body 3 from sliding downward relative to the first window body 2 during overturning, in some embodiments, as Figure 8 , Figure 16 AndFigure 20 As shown, the window structure of the present application further comprises a first locking mechanism 8 for releasably locking the superposed first window body 2 and second window body 3, the first locking mechanism 8 comprises a first lock tongue 801 and a first lock body 802 which can be mutually clamped, one of the first lock tongue 801 and first lock body 802 is arranged on the first window body 2 and the other is arranged on the second window body 3, the first lock tongue 801 and first lock body 802 lock the first window body 2 and second window body 3 together by clamping to prevent the second window body 3 from accidentally sliding down.

[0092] In some embodiments, as shown in Figure 16 and Figure 20 , the first lock tongue 801 is arranged on the first cross bar 203 below the first window frame, the lower end of the first lock tongue 801 has a first clamping hook 803, the second lock body 902 is arranged on the second cross bar 303 below the second window frame, the first lock body 802 has a second clamping hook 804 which can be popped out and retracted, the second clamping hook 804 has a guide slope towards the first window body 2, when the second window body 3 is slid upwards to be superposed with the first window body 2, the first clamping hook 803 slides along the guide slope to below the second clamping hook 804 and clamps with the second clamping hook 804, thereby locking the first window body 2 and second window body 3 together. When it is necessary to unlock, pressing the button 805 on the first lock body 802 makes the second clamping hook 804 retract, thereby releasing the clamping of the second clamping hook 804 with the first clamping hook 803, so that the second window body 3 can be slid downwards to close the window structure.

[0093] Figure 16 and Figure 20 Only one example of the first locking mechanism 8 is provided, which does not limit the scope of the present application, the first locking mechanism 8 can also be other lockable and unlockable structures.

[0094] In order to prevent the first window body 2 and second window body 3 from being undesirably flipped over, in some embodiments, as shown in Figure 8 , Figure 17 , Figure 21 the window structure of the present application further comprises a second locking mechanism 9 for releasably locking the first window body 2 in the unflipped state with the frame 1, the second locking mechanism 9 comprises a second lock tongue 901 and a second lock body 902 which can be mutually clamped, one of the second lock tongue 901 and second lock body 902 is arranged on the first window body 2 and the other is arranged on the frame 1, the second lock tongue 901 and second lock body 902 lock the first window body 2 and frame 1 together by clamping to prevent the first window body 2 and second window body 3 from accidentally flipping over.
