Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of window locking devices, specifically a window locking mechanism with a concealed handle that integrates manual and automatic locking. Background Technology
[0002] Existing door and window locking mechanisms either use manual mechanisms, automatic unlocking mechanisms, or can achieve manual and automatic locking but require a handle, such as the Chinese patent "Manual and Automatic Intelligent Window Opener", with authorization announcement number CN218598015 U. The window opener disclosed in this patent requires a handle to manually open and close the window when it is in manual mode. The handle is a regular handle, and the rack and pinion drive the transmission lock bar (transmission device) on the window and the outer door and window handle to unlock the window.
[0003] Manual locking mechanisms are unsuitable for the requirements of modern smart homes, while fully automatic locking mechanisms are difficult to open and close in the event of a power outage or other malfunctions, and are also difficult to maintain. Furthermore, existing manual-automatic locking mechanisms have a long manual handle, resulting in an unsightly appearance. Utility Model Content
[0004] This utility model provides a window locking mechanism with a hidden handle that integrates manual and automatic locking, taking into account the requirements of smart homes. If the automatic locking mechanism fails, the manual locking mechanism can still be used. The handle of the manual locking mechanism has been improved to a hidden handle, which takes up little space when not in use and does not affect the appearance.
[0005] Therefore, the present invention provides the following technical solution:
[0006] A window locking mechanism with a concealed handle, comprising an automatic locking device and a concealed handle device connected to the window respectively; the automatic locking device includes an output gear and a locking slider rod, the locking slider rod having a rack meshing with the output gear, the locking slider rod being driven by the output gear to move horizontally to complete locking and unlocking; the concealed handle device performs manual locking, including a handle base, a handle cover, and an unlocking linkage rod, one end of the unlocking linkage rod being non-rotatably connected to the output gear, the other end passing through the middle of the handle base and being rotatably connected to the handle base, the inner side of the handle base being connected to the window, the handle cover being configured to fit the shape of the handle base and being magnetically attached to the outer side of the handle base, the handle cover having a central groove in the middle of the side of the handle base that can accommodate the end of the unlocking linkage rod, and the side of the handle cover that is close to the handle base also having a blind hole for unlocking that is non-rotatably connected to the end of the unlocking linkage rod.
[0007] In this solution, the automatic locking device is installed inside the window or door frame, while the concealed handle device is located on the outside of the window or door frame. The two are connected by an unlocking linkage. The output gear of the automatic locking device drives the locking slider to move, thus completing the locking and unlocking actions. If the automatic locking device fails, the concealed handle device can be used for manual locking. The handle base and handle cover of the concealed handle are fitted together, and the handle base is fixed to the window or door frame. When using the automatic locking method, the rotation of the output gear drives the locking slider to move horizontally. Simultaneously, the rotation of the output gear also drives the unlocking linkage to rotate. Since the unlocking linkage is rotatably connected to the handle base, it is not connected to the handle cover at this time. This handle cover is magnetically attached to the outside of the handle base and does not rotate. Its compact size saves space. For manual locking, the handle cover is removed from the handle base, and the blind hole on the handle cover is used to connect with the unlocking linkage without rotation. Rotating the handle cover then causes the unlocking linkage to rotate together, thus locking or unlocking. The blind hole on the handle cover can be located at both ends for easy use on left or right window or door frames. The "non-rotational connection" mentioned in this design means that the two components rotate together without relative rotation. The components can be connected by a triangular rod and triangular hole, a square rod and square hole, or an elliptical shaft and elliptical hole, etc.
[0008] In a preferred embodiment of this utility model, the handle base is provided with a rotating disk, which is rotatably connected to the handle base. One end of the unlocking linkage is not rotatably connected to the inner side of the rotating disk, and a protruding unlocking boss is provided in the middle of the outer side of the rotating disk. When manually unlocking or locking, one end of the unlocking linkage is rotatably connected to the unlocking blind hole of the handle cover through the unlocking boss. In this embodiment, the unlocking linkage is rotatably connected to the handle base through the rotating disk. The friction between the rotating disk and the handle base is relatively large when they rotate, which can increase the rotational resistance of the unlocking linkage and prevent the locking slider from automatically sliding down due to gravity when manually locking, thus avoiding locking failure.
[0009] In a preferred embodiment of this utility model, the handle base is provided with an embedding hole, and symmetrical spring grooves are provided on the outer side of the embedding hole and the inner side of the handle base. A spring is installed in each of the spring grooves. The rotating disc is disposed within the embedding hole, and ball grooves are evenly distributed on the outer side of the rotating disc. A ball is provided at the contact end between the spring and the outer side of the rotating disc. This design fixes the frictional force between the rotating disc and the handle base during rotation as spring resistance, facilitating calculation and setting. The rotating disc needs to overcome the spring resistance to rotate; that is, when the rotating disc rotates, it needs to push the ball from the bottom to the top of the ball groove to enter the next ball groove.
[0010] In a preferred embodiment of this invention, the outer side of the handle base is provided with symmetrical magnetic grooves, each containing a magnet. A protruding positioning ring is located at the opening of each magnetic groove. The side of the handle cover that is flush with the handle base is provided with a second magnetic groove corresponding to the first magnetic groove. A magnet is located in the second magnetic groove, and a positioning groove corresponding to the positioning ring is located at the opening of the second magnetic groove. In this design, the handle cover and handle base are precisely positioned by the positioning ring and positioning groove, ensuring a neat and consistent appearance. They are magnetically connected by magnets, which can be permanent magnets.
[0011] As a preferred embodiment of this utility model, the automatic locking device further includes a housing, a motor, and a gear transmission device. A slide rail is provided on one side of the housing, and the locking slider is slidably connected to the slide rail. The motor and the gear transmission device are located inside the housing. The gear transmission device is a multi-stage transmission gear set, and the output gear is the last stage transmission gear.
[0012] As a preferred embodiment of this utility model, the multi-stage transmission gear set includes a clutch gear set, which includes a V-shaped bracket. The two ends of the V-shaped bracket are respectively provided with a first clutch gear or a second clutch gear. The first clutch gear and the second clutch gear respectively mesh with the next-stage transmission gear close to the motor. The middle part of the V-shaped bracket is rotatably connected to the housing. After the V-shaped bracket rotates in the forward or reverse direction, one of the first clutch gear and the second clutch gear meshes with the next-stage transmission gear. The locking mechanism of a manual / automatic system usually requires switching between manual and automatic modes. This solution uses a clutch gear set as the device for switching between automatic and manual locking modes. The motor can rotate in both directions. When the motor rotates, it drives the multi-stage gears to rotate. The first and second clutch gears at both ends of the V-shaped bracket rotate with the upper-level transmission gear. Since the V-shaped bracket itself is rotatably connected to the housing, the first and second clutch gears, while meshing and rotating with the upper-level transmission gear, will drive the V-shaped bracket to rotate in the same direction as the upper-level transmission gear until one of the first and second clutch gears meshes with the next-level transmission gear. Then, the entire multi-stage transmission gear set begins to rotate, and the output gear drives the locking slider to move. After the locking slider moves to its position, the motor briefly outputs rotation in the opposite direction, causing the first or second clutch gear to disengage from the next-level transmission gear. After this, the automatic locking mode can continue to be used, or the manual locking mode can be used directly.
[0013] In a preferred embodiment of this invention, the locking slider rod is provided with limiting posts at both ends. The function of the limiting posts is to prevent the locking slider rod from deviating after it has moved into position.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] It takes into account the requirements of smart homes. If the automatic locking mechanism fails, the manual locking mechanism can still be used. The handle of the manual locking mechanism has been improved to a hidden handle, which takes up little space and does not affect the appearance when not in use. Attached Figure Description

[0039] The multi-stage transmission gear set includes a clutch gear set, which includes a V-shaped bracket 27. The two ends of the V-shaped bracket 27 are respectively provided with a first clutch gear 28 or a second clutch gear 29. The first clutch gear 28 and the second clutch gear 29 respectively mesh with the previous stage transmission gear close to the motor 24. The middle part of the V-shaped bracket 27 is rotatably connected to the housing 23. After the V-shaped bracket 27 rotates in the forward or reverse direction, one of the first clutch gear 28 and the second clutch gear 29 meshes with the next stage transmission gear.
[0040] Limiting posts 30 are provided at both ends of the locking slider rod 4.
[0041] The specific usage process of this utility model is as follows: When the motor 24 rotates forward, the first clutch gear 28 and the second clutch gear 29 are driven to rotate by the upper-level transmission gear 31, which in turn drives the V-shaped bracket 27 to rotate. The V-shaped bracket 27 rotates until the first clutch gear 28 meshes with the next-level transmission gear 32, which is away from the motor 24. After the output gear 3 drives the locking slider 4 to move into place, the motor 24 reverses. Therefore, the first clutch gear 28 and the second clutch gear 29 are driven to rotate in the opposite direction by the upper-level transmission gear 31, which in turn drives the V-shaped bracket 27 to rotate, until the first clutch gear 28 disengages from the next-level transmission gear 32.
[0042] When the motor 24 reverses, the first clutch gear 28 and the second clutch gear 29 are driven to rotate in the opposite direction by the previous stage transmission gear 31, which in turn drives the V-shaped bracket 27 to rotate. The V-shaped bracket 27 rotates until the second clutch gear 29 meshes with the next stage transmission gear 32, which is away from the motor 24. After the output gear 3 drives the locking slider 4 to move into place, the motor 24 rotates forward. The first clutch gear 28 and the second clutch gear 29 are driven to rotate forward by the previous stage transmission gear 31, which in turn drives the V-shaped bracket 27 to rotate, until the second clutch gear 29 disengages from the next stage transmission gear 32.
[0043] When manual locking is required, remove the handle cover 7 from the handle base 6, connect the unlocking blind hole 10 on the handle cover 7 to the unlocking linkage 8 without rotation, and then rotate the handle cover 7 to rotate the unlocking linkage 8 together to achieve locking and unlocking. The unlocking blind hole 10 on the handle cover 7 can be set at both ends of the handle cover 7, so that the handle cover 7 can be used on the left and right window frames or door frames.
