Description

Technical Field

[0001] The utility model relates to the technical field of doors and windows, in particular to a fault-proof window. Background Art

[0002] Currently, all electric windows on the market are equipped with a clutch device. When there is no power, the clutch device disconnects, allowing users to manually open and close the window. However, when the clutch device malfunctions, the window remains locked, and users cannot manually unlock the window to open it normally, which causes great inconvenience to the user. In the event of a clutch device failure, users can only remove the motor by violently destroying it to repair the clutch device. However, windows that have been violently destroyed will suffer varying degrees of damage, affecting their performance and rendering them inoperable, thus affecting the user experience. Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides a fail-safe window that can be manually unlocked in the event of a malfunction in the electric drive component, allowing for easy disassembly and repair of the electric drive component, preventing subsequent malfunction of the window.

[0004] The present invention provides a fail-safe window having a first direction and a second direction perpendicular to each other, comprising:

[0006] a window sash, which is arranged in the window and movably connected to the window frame;

[0007] A manual locking mechanism comprising a handle, a first transmission lock box, and a first locking member, wherein the handle is rotatably mounted on the window sash, the first transmission lock box is mounted on the window sash, and the handle is configured to drive the first locking member to move in a second direction via the first transmission lock box;

[0008] An electric locking mechanism includes an electric drive component and a second locking component. The electric drive component is provided on the window frame. The second locking component is arranged opposite to the first locking component. The electric drive component is configured to drive the second locking component to move. When the first locking component or the second locking component is activated, the second locking component is snap-connected with the first locking component to lock the window sash to the window frame.

[0009] The fault-proof window provided by the present invention has at least the following beneficial effects: when the electric drive component is in a state where it can be used normally, the fault-proof window can drive the second locking component to be connected with the first locking component through the electric drive component, thereby locking the window sash to the window frame without the need for manual rotation of the handle, thereby realizing automatic window locking. When the electric drive component fails, the second locking member is in a fixed state, and the user can rotate the handle on the window sash to allow the handle to drive the first locking member to move in the second direction through the first transmission lock box, thereby releasing the snap connection between the first locking member and the second locking member, thereby releasing the locked state of the window sash so that the window sash can be opened. Moreover, when the window sash is in the open state, it is convenient to remove the electric drive component and perform maintenance. With such a structural design, there is no need to destroy the window by force to remove the electric drive component, thereby ensuring that the window can be used normally afterwards. In addition, before the electric drive component is repaired, the user can fix the second locking member and manually rotate the handle to drive the first locking member to snap connect or release the snap connection with the second locking member, thereby locking or unlocking the window, making the fault-proof window robust and ensuring a good experience for users when using the window in daily life.

For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0029] Reference below Figures 1 to 5 A fail-safe window according to an embodiment of the present invention is described.

[0030] like Figures 1 to 5As shown, the first embodiment of the present invention provides a fail-safe window. The fail-safe window of this embodiment has a first direction, a second direction, and a third direction, wherein the first direction, the second direction, and the third direction are perpendicular to each other. For a clearer illustration, in this embodiment, it is assumed that the first direction is the front-to-back direction, the second direction is the up-down direction, and the third direction is the left-to-right direction.

[0031] The fail-safe window of this embodiment includes a window frame 100 , a window sash 200 , a manual locking mechanism, and an electric locking mechanism.

[0032] The window frame 100 can be made of materials such as aluminum alloy or plastic steel. The window frame 100 has a window 110 extending along a first direction. One side of the window 110 along the first direction faces the outside, while the other side of the window 110 along the first direction faces the inside. The window frame 100 is rectangular or square in shape. In this embodiment, the window frame 100 is formed by connecting multiple aluminum profiles and forming a rectangular window 110.

[0033] Window sash 200 is positioned within window 110. Its shape matches that of window 110, allowing it to shield and seal window 110 within window frame 100. Furthermore, sash 200 is movably connected to window frame 100, enabling the fail-safe window to be either a casement or sliding window. Window sash 200 is primarily composed of a combination of glass panels and multiple aluminum profiles.

[0034] In some embodiments, one side of the window sash 200 along the third direction is pivotally connected to one side of the window frame 100 along the third direction, and the pivotal structure includes a pivot, a sleeve, and a hinge. The pivot is a solid metal cylindrical shaft, and the hinge is connected to the pivot for connecting the window sash 200 and the window frame 100. The sleeve is installed between the pivot and the hinge to reduce the friction between the pivot and the hinge, making the rotation smoother. The material of the sleeve can be bronze, brass, etc., which has good wear resistance and a low friction coefficient. It is understandable that the fault-proof window can be an outward-opening casement window or an inward-opening casement window. The hinge axis of the window sash 200 can extend in the up-down direction or in the left-right direction.

[0035] In this embodiment, the window sash 200 and the window frame 100 are connected in a hinged manner. A window sash 200 is installed at the window 110 of the window frame 100. The window sash 200 can be rotated toward the outside of the window frame 100 relative to the window frame 100 to open the window sash 200; and can be rotated toward the inside of the window frame 100 relative to the window frame 100 to close the window sash 200.

[0036] In other embodiments, the window sash 200 and the window frame 100 can be connected by a sliding rail, which is arranged on both sides of the window frame 100 along the second direction. The length of the sliding rail extends along the third direction. The window sash 200 can be connected to the sliding rail through rollers. Two window sashes 200 are installed at the window 110 of the window frame 100. The window sash 200 can slide relative to the sliding rail along the third direction, thereby moving within the window 110 of the window frame 100, realizing the push-pull function of the window sash 200 relative to the window frame 100.

[0037] The manual locking mechanism includes a handle 310, a first transmission lock box 320, and a first locking member. The handle 310 is rotatably mounted on the window sash 200, allowing users to rotate the handle 310. When the window sash 200 is closed, the handle 310 is located indoors. The handle 310 is located at one end of the window sash 200 along the third direction, with its rotation axis extending along the first direction. The handle 310 can rotate clockwise or counterclockwise relative to the window sash 200.

[0038] The first transmission lock box 320 is disposed on the window sash 200. Specifically, the aluminum profile of the window sash 200 is provided with a mounting cavity, and the first transmission lock box 320 is embedded and mounted in the mounting cavity of the window sash 200 via bolts. The first transmission lock box 320 is located on a side surface of the window sash 200 along the third direction, adjacent to the handle 310. The first transmission lock box 320 and the handle 310 are connected by a rotating shaft, and the actuating end of the first transmission lock box 320 is connected to the first locking member. The handle 310 is configured to drive the first locking member to move in the second direction via the first transmission lock box 320.

[0039] It can be understood that the first transmission lock box 320 is an existing technology. A first transmission mechanism is provided in the first transmission lock box 320. The first transmission mechanism can be a gear transmission structure or a connecting rod transmission structure. The handle 310 can drive the first transmission mechanism in the first transmission lock box 320 to move through the rotating shaft. The first transmission mechanism of the first transmission lock box 320 can drive the first locking member to move.

[0040] In some embodiments, as Figure 1 、 Figures 3 to 5As shown, the first locking member includes a first locking rod 331 and a locking point 332, with the locking point 332 being disposed on the first locking rod 331. In this embodiment, the first locking rod 331 and the locking point 332 are located on the right side of the window sash 200. The length of the first locking rod 331 extends along the second direction. One end of the first locking rod 331 is fixedly connected to the first transmission mechanism within the first transmission lock box 320, and the locking point 332 is disposed at the other end of the first locking rod 331. The first locking rod 331 and the locking point 332 are fixedly connected. The user can rotate the handle 310 to cause the handle 310 to move the first transmission mechanism within the first transmission lock box 320, thereby causing the first transmission lock box 320 to move the first locking rod 331 in the second direction, allowing the locking point 332 to cooperate with the electric locking mechanism to achieve the locking function of the window sash 200.

[0041] When the window sash 200 is in the locked state, the handle 310 and the first transmission lock box 320 are both located on one side of the window sash 200 along the third direction, and the electric locking mechanism is arranged on the side of the window frame 100 close to the handle 310 along the third direction. The electric locking mechanism and the manual locking mechanism are arranged opposite to each other in the third direction.

[0042] The electric locking mechanism includes an electric drive component 410 and a second locking member. The electric drive component 410 is mounted on the window frame 100. Specifically, the window frame 100 has a receiving cavity, into which the electric drive component 410 is embedded and bolted. The second locking member is positioned opposite the first locking member. The actuator end of the electric drive component 410 is fixedly connected to the second locking member and is configured to actuate the second locking member.

[0043] Furthermore, when the first locking member or the second locking member is activated, a snap connection is established between the first locking member and the second locking member to lock the window sash 200 to the window frame 100, thereby achieving the locking function of the window sash 200. When the first locking member or the second locking member is activated in the reverse direction, the snap connection between the first locking member and the second locking member is released to release the locked state of the window sash 200, thereby facilitating subsequent opening of the window sash 200.

[0044] It is understood that in some embodiments, the window sash 200 can rotate relative to the window frame 100 to achieve opening and closing of the window sash 200. In this case, the electric drive component 410 can drive the second locking member to move linearly in the second direction, causing the second locking member to move relative to the first locking member, thereby enabling the second locking member to establish a snap connection with the first locking member to lock the window sash 200 to the window frame 100. Of course, it is not ruled out that in other embodiments, the electric drive component 410 drives the second locking member to rotate, with the rotation axis of the second locking member extending along the third direction. After the second locking member rotates a certain angle, the second locking member can snap into contact with the first locking member, causing the second locking member to hinder the rotation and opening of the window sash 200, thereby achieving the locking function of the window sash 200.

[0045] In other embodiments, the window sash 200 can slide linearly along a third direction relative to the window frame 100 to achieve opening and closing of the window sash 200. At this time, the electric drive component 410 can drive the second locking member to move linearly along the second direction relative to the first locking member, so that the first locking member and the second locking member can be snap-connected, thereby locking the window sash 200 on the window frame 100 and preventing the window sash 200 from sliding.

[0046] In some embodiments, the electric drive component 410 includes a rotary drive member and a second transmission lock box, the execution end of the rotary drive member is fixedly connected to the second transmission lock box, the execution end of the second transmission lock box is fixedly connected to the second locking member, and the rotary drive member is configured to drive the second locking member to move linearly along the second direction through the second transmission lock box.

[0047] It can be understood that the rotary drive member may include a drive motor and a transmission structure, the transmission structure may be a coupling, a reducer, etc., the second transmission lock box is a prior art, and a second transmission mechanism is provided in the second transmission lock box, the second transmission mechanism may be a gear transmission mechanism or a connecting rod transmission mechanism, the output end of the rotary drive member is fixedly connected to the second transmission mechanism, and the execution end of the second transmission mechanism is fixedly connected to the second locking member.

[0048] In this embodiment, if Figure 1 、 Figures 3 to 5 As shown, the second locking member includes a second locking rod 421 and a locking seat 422. The locking seat 422 is disposed on the second locking rod 421, and the second locking rod 421 and the locking seat 422 are fixedly connected. When the window sash 200 is in the locked state, the second locking rod 421 is disposed opposite the first locking rod 331. Moreover, the first locking rod 331 and the second locking rod 421 can move relative to each other in the second direction, so that the locking point 332 on the first locking rod 331 can be snap-connected to the locking seat 422 on the second locking rod 421.

[0049] It can be understood that under normal circumstances, the handle 310 is in the locked position, that is, the handle 310 is rotated to a position parallel to the second direction. At this time, the first locking rod 331 and the locking point 332 are in a fixed position, and the rotating drive member can drive the second transmission lock box to work, so that the second locking rod 421 moves along the second direction under the driving action of the second transmission lock box, and the second locking rod 421 drives the lock seat 422 to move along the second direction, so that the lock seat 422 can engage with the locking point 332, thereby realizing the locking of the window sash 200.

[0050] When the electric drive component 410 fails, the second locking rod 421 and the lock seat 422 cannot move in the second direction. At this time, the user can rotate the handle 310 and drive the first transmission lock box 320 to work through the handle 310, so that the first locking rod 331 drives the locking point 332 to move in the second direction under the driving action of the first transmission lock box 320, so that the locking point 332 and the lock seat 422 can be snap-connected or snap-disconnected.

[0051] In some examples, the lock base 422 has a slot, and the locking point 332 can move upward relative to the lock base 422 and snap into the slot of the lock base 422. In other examples, the locking point 332 can move downward relative to the lock base 422 and snap into the slot of the lock base 422.

[0052] Of course, it is not ruled out that in other embodiments, the structures of the first locking member and the second locking member are interchangeable, that is, the lock seat 422 belongs to the structural part of the first locking member, and the locking point 332 belongs to the structural part of the second locking member.

[0053] In this embodiment, if Figure 1 、 Figures 3 to 5 As shown, the first transmission lock box 320 is provided with first locking elements on both sides along the second direction. The first transmission lock box 320 is configured to drive the first locking elements on both sides of the first transmission lock box 320 toward or away from each other in the second direction. The second transmission lock box is provided with second locking elements on both sides along the second direction. The second transmission lock box is configured to drive the second locking elements on both sides of the second transmission lock box toward or away from each other in the second direction.

[0054] It is understood that such a design can ensure that both sides of the window sash 200 along the second direction are subjected to a certain snap connection effect, so that the window sash 200 is evenly stressed. Of course, it is not excluded that in other embodiments, the first transmission lock box 320 is provided with a first locking member on one side along the second direction, and the second transmission lock box is provided with a second locking member on one side along the second direction, with the first locking member and the second locking member being on the same side in the second direction and arranged opposite each other.

[0055] In some embodiments, as Figure 1As shown, the fail-safe window also includes a fixing screw 500. The second locking member is detachably connected to the electric drive component 410. Specifically, the second locking rod 421 of the second locking member and the second transmission lock box of the electric drive component 410 can be connected by screws or a pin. The second locking member has a first connection hole, which can be a screw hole or a smooth circular hole. The window frame 100 has a second connection hole, which is a screw hole. Specifically, the first connection hole is provided on the second locking rod 421, and the axial direction of the first connection hole and the axial direction of the second connection hole are aligned. Furthermore, the fixing screw 500 is configured to connect to the first and second connection holes when the electric drive component 410 is removed, thereby securing the second locking member to the window frame 100.

[0056] It is understood that when the electric drive component 410 malfunctions, the user can first rotate the handle 310 to release the snap connection between the first and second locking members, then open the window sash 200 to create space for removing the electric drive component 410 from the window frame 100. While the electric drive component 410 is under repair, to ensure normal use of the window, the user can use a screwdriver to screw the fixing screws 500 into the first and second connection holes, respectively, to secure the second locking member to the window frame 100. The user can then rotate the handle 310 to drive the first locking rod 331 in the second direction, causing the locking point 332 to engage with the lock seat 422, thereby locking the window sash 200 and allowing normal use of the window.

[0057] In the above-mentioned embodiment, the fault-proof window is a casement window or a sliding window. When the window sash 200 is in a locked state, the handle 310, the first transmission lock box 320 and the first locking member are all located on one side of the window sash 200 along the left-right direction, and the electric drive component 410 and the second locking member are both located on one side of the window frame 100 along the left-right direction and are arranged close to the handle 310.

[0058] In addition, it is not ruled out that in other embodiments, when the window sash 200 is in a locked state, the handle 310 and the first transmission lock box 320 are both arranged on one side of the window sash 200 in the left-right direction, and the window sash 200 is provided with a first locking member on one side or both sides in the up-down direction. At this time, the first locking rod 331 of the first locking member includes a first rod body, a connecting rod, and a second rod body. The length of the first rod body extends in the up-down direction, one end of the first rod body is fixedly connected to the execution end of the first transmission lock box 320, the length of the second rod body extends in the left-right direction, one end of the connecting rod is hinged to the other end of the first rod body, the other end of the connecting rod is hinged to one end of the second rod body, and the other end of the second rod body is provided with a locking point 332 or a lock seat 422.

[0059] Then, when the handle 310 is manually driven to rotate, the handle 310 can drive the first rod to move in the up-down direction through the first transmission lock box 320, and the second rod can move in the left-right direction under the connection of the connecting rod. In this case, the second direction is the left-right direction.

[0060] Furthermore, an electric drive component 410 and a second locking member are provided on one or both sides of the window frame 100 in the vertical direction. The electric drive component 410 can drive the second locking member to rotate about an axis extending vertically, thereby engaging the first locking member and preventing the window sash 200 from being rotated and opened. Alternatively, the electric drive component 410 can drive the second locking member to move horizontally, thereby engaging the second locking member with the first locking member and preventing the window sash 200 from being rotated and opened.

[0061] In some embodiments, the fail-safe window further includes an electric window opening mechanism. The window sash 200 is hinged to the window frame 100. When the window sash 200 is in a locked state, the handle 310 is located on one side of the window sash 200 along the first direction, that is, the handle 310 is located on the indoor side, making it convenient for the user to hold it with his hand. The electric window opening mechanism is configured to drive the window sash 200 to swing toward the other side of the window sash 200 along the first direction to open the window sash 200. It is understandable that the electric window opening mechanism can be an existing window opener, such as a chain electric window opener. The electric window opening mechanism is installed on the upper side or the lower side of the window frame 100, and the execution end of the electric window opening mechanism is connected to the window sash 200.

[0062] In this embodiment, if Figures 2 to 5 As shown, the electric window opening mechanism includes a rotary drive component 610, a transmission rod 620, and a slider 630. When the window sash 200 is locked, the rotary drive component 610 is detachably connected to the window frame 100. The rotary drive component 610 is located on one side of the window 110 along the second direction and on the side of the window sash 200 along the first direction that is closer to the handle 310. Specifically, the rotary drive component 610 is located closer to the indoor side, while the window sash 200 is located closer to the outdoor side.

[0063] Furthermore, the window sash 200 is provided with a guide rail 210, which extends in the third direction. The guide rail 210 is located on one side of the window sash 200 in the second direction and is disposed proximate to the rotational drive component 610. A slider 630 is slidably connected to the guide rail 210. The guide rail 210 may be a T-shaped slot, and the slider 630 can only slide along the direction in which the guide rail 210 extends. One end of the transmission rod 620 is detachably connected to the output end of the rotational drive component 610, allowing the transmission rod 620 to rotate about the output end of the rotational drive component 610. The other end of the transmission rod 620 is hingedly connected to the slider 630 via a hinge shaft. The rotation axis and the hinge axis of the transmission rod 620 both extend in the second direction.

[0064] It is understood that the rotary drive component 610 may be a drive motor, with the rotary shaft of the drive motor being connected to one end of the transmission rod 620 via a coupling or key connection, thereby securing the transmission rod 620 to the rotary shaft of the drive motor. A lubricant is present between the slider 630 and the guide rail 210 to reduce friction therebetween, facilitating easy opening and closing of the window sash 200.

[0065] When the rotary drive component 610 is running, the output end of the rotary drive component 610 can drive the transmission rod 620 to swing around the rotation axis extending up and down. At this time, the slider 630 will be driven by the transmission rod 620, so that the slider 630 can slide along the guide rail 210. At the same time, the slider 630 will rotate relative to the transmission rod 620 around the hinge axis extending up and down. In the process of sliding of the slider 630, the window sash 200 can swing clockwise or counterclockwise around the hinge between it and the window frame 100, thereby realizing the opening and closing of the window sash 200.

[0066] The rotary drive component 610 and the window sash 200 are staggered in the first direction. After the window sash 200 is closed, the rotary drive component 610 is located on the indoor side, which can prevent the rotary drive component 610 from being affected by the outdoor side.

[0067] Moreover, when the rotary drive component 610 fails and the window sash 200 is in a closed state, although the locked state of the window sash 200 can be released, since the rotary drive component 610 is connected to the window sash 200 through the transmission rod 620 and the slider 630, the user cannot manually open the window sash 200. At this time, because the rotary drive component 610 is arranged close to the indoor side and forms an inside-outside staggered arrangement with the window sash 200, the user can directly remove the rotary drive component 610 from the window frame 100 and the transmission rod 620 and perform maintenance without damaging the window frame 100, and it is convenient for the user to manually open the window sash 200 later.

[0068] In some embodiments, as Figure 2 and Figure 3 As shown, the electric window opening mechanism further includes a decorative cover plate 640, which is detachably connected to the window frame 100 so that the decorative cover plate 640 and the window frame 100 jointly form a protective cavity 650 for accommodating the rotary drive component 610. The decorative cover plate 640 is located on a side of the window sash 200 that is closer to the handle 310 along the first direction, that is, the decorative cover plate 640 is located on the indoor side. The decorative cover plate 640 is provided with a through hole 641, which is located on the side of the decorative cover plate 640 that is closer to the window sash 200 and communicates with the protective cavity 650. The provision of the through hole 641 enables the transmission rod 620 to pass through and swing.

[0069] It is understood that when the rotary drive component 610 is in normal use, one end of the transmission rod 620 is connected to the output end of the rotary drive component 610 and passes through the through hole 641 of the decorative cover plate 640, so that the other end of the transmission rod 620 can be hinged to the slider 630 on the window sash 200. When the rotary drive component 610 is activated, the transmission rod 620 and the slider 630 cooperate to enable the window sash 200 to open and close automatically without manual operation.

[0070] When the rotating drive component 610 fails, the user can open the decorative cover 640 and remove the rotating drive component 610. At this time, the transmission rod 620 can move in the through hole 641, and the user can manually control the handle 310 to manually open and close the window sash 200, which will not affect the daily use of the window.

[0071] It is understood that a single electric window opening mechanism can be provided for a window, or two electric window opening mechanisms can be provided simultaneously. If there is only one electric window opening mechanism, the electric window opening mechanism can be provided on the upper or lower side of the window 110, without limitation. If there are two electric window opening mechanisms, one electric window opening mechanism is provided on the upper and lower sides of the window 110, respectively. If the rotary drive component 610 in one of the electric window opening mechanisms fails, the failed rotary drive component 610 can be removed, while the other electric window opening mechanism can continue to operate normally, automatically driving the window sash 200 to open and close.
