Description

Technical Field

[0001] This utility model relates to the field of window lock technology, and in particular to a window lock. Background Technology

[0002] In the construction industry, windows serve as crucial channels for indoor and outdoor ventilation and lighting, and their safety and convenience have always been core design concerns. Among these, window locks, as key components ensuring the stability of the window sash when closed and preventing accidental opening or unauthorized intrusion, have their structural and functional designs directly impacting the overall performance of the window sash.

[0003] For a long time, most window sashes on the market have used manual locks to achieve the locking function. These manual locks typically include a lock body, bolt, and handle. Users manually operate the lock by rotating the handle or pressing the latch, causing the bolt to engage with the keyhole on the window frame, thus locking or opening the window. Manual locks are widely used in various building doors and windows due to their simple structure, low cost, and high reliability. However, with the improvement of people's living standards and the increasing demand for home convenience, the limitations of manual locks requiring close-range manual operation have gradually become apparent. Especially in high-rise residential buildings and large commercial buildings, manually locking window sashes is not only inconvenient but may also lead to insecure locking due to negligence, posing a safety hazard.

[0004] In recent years, with the rapid development of smart home technology, various smart window openers have gradually emerged on the market to meet users' needs for automated window control. These smart window openers typically use electric push rods, motors, or other drive components, and automatically open or close windows by receiving remote control signals, sensor commands, or linking with smart home systems. The application of smart window openers greatly improves the convenience of window operation, making them especially suitable for the elderly, children, or those with mobility impairments. They can also be used in conjunction with wind and rain sensors, smoke sensors, etc., to achieve automatic emergency opening and closing of windows, further enhancing home security and the level of smart technology.

[0005] However, existing smart window openers still have significant technical shortcomings in practical applications: their drive structure is primarily designed for the opening and closing of window sashes and cannot be effectively adapted to traditional manual locks. Specifically, when the smart window opener drives the window sash to close, the traditional manual lock still requires manual operation by the user to complete the locking, resulting in the smart window opener's automation function not being fully utilized. If the smart window opener's drive components are forcibly used to directly drive the manual lock, the differences in locking stroke and force application between the manual lock and the window sash's opening and closing actions may not only damage the lock due to mismatched drive forces but also lead to problems such as incomplete locking and accidental locking, affecting the window sash's locking reliability. Utility Model Content

[0006] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes an intelligent electric window lock.

[0007] A window lock designed for this purpose includes a lock body, a bolt, a lock housing, and an electric drive assembly. The lock housing has a keyhole, and the bolt is movably disposed relative to the lock body and can extend into the keyhole. A rotating component is rotatably disposed within the lock body, and the rotating component has a lever. The bolt has a lever engagement groove. The lever is movably disposed within the lever engagement groove and can abut against the groove wall, thereby pushing the bolt to move relative to the lock body. The electric drive assembly is disposed within the lock body and is drively connected to the rotating component.

[0008] Preferably, the electric drive assembly includes a drive motor, a drive gear, and a driven gear;

[0009] The drive motor is fixedly mounted in the lock body, the drive gear is fixedly mounted on the motor shaft of the drive motor, and the driven gear is connected to the rotating part and is driven by the drive gear.

[0010] Preferably, the latch is disposed inside the lock body, and the lock body has an opening on the wall facing the lock box; the latch is at least partially disposed in the opening and can move through the opening into the keyhole to form a lock.

[0011] Preferably, the latch is provided with a guide groove, and the lock body is connected to a guide member, which is inserted into the guide groove.

[0012] Preferably, the rotating component is provided with a connecting member, the connecting member is connected to a compression spring, and the other end of the compression spring is connected to the lock body.

[0013] Preferably, the lock box is detachably connected to a mounting pad.

[0014] Preferably, the lock body is provided with a control switch, the lock body is provided with a control circuit board, the control switch is electrically connected to the control circuit board, and the control circuit board is electrically connected to the electric drive assembly.

[0015] Preferably, the lock body is provided with a knob for rotation, and the knob is connected to the rotating component for transmission.

[0016] Compared with the prior art, the window lock provided by this invention has significant technical advantages and practical value, with the following specific beneficial effects:

[0017] Firstly, it achieves efficient compatibility with smart window openers. By integrating an electric drive component into the lock body and utilizing its transmission connection with the rotating parts, it can directly drive the bolt to complete locking or unlocking actions without relying on manual operation. This design solves the technical pain point of existing smart window openers, which can only control the opening and closing of the window sash and cannot be linked with the lock. It enables the window lock to work collaboratively with the smart window opener. When the smart window opener drives the window sash to close, the electric drive component can simultaneously drive the bolt to extend into the keyhole of the lock box, realizing the automatic locking of the window sash and fully utilizing the automation function of the smart control system.

[0018] Secondly, it improves the stability and reliability of the locking action. The solution uses the actuating lever of the rotating component and the actuating groove of the locking tongue to convert the rotational motion of the electric drive assembly into the linear movement of the locking tongue. This results in a simple transmission structure and high transmission efficiency. It effectively avoids problems such as incomplete locking and accidental locking that may occur with traditional manual locks, further enhancing the security of the window sash.

[0019] Third, it has a compact structure and strong applicability. The core components such as the electric drive assembly and rotating parts are all integrated into the lock body. The overall structure is compact and can be installed and used without major modifications to the window sash or frame. It is not only suitable for smart window systems in new buildings, but also easy to upgrade existing window sashes with manual locks, lowering the application threshold and facilitating its promotion and application in various building scenarios.

[0032] See Figures 1-4 A window lock includes a lock body 10, a bolt 20, a lock housing 60, and an electric drive assembly 40. The lock housing 60 has a lock hole 600, and the bolt 20 is movably disposed relative to the lock body 10 and can extend into the lock hole 600. A rotating member 30 is rotatably disposed within the lock body 10, and the rotating member 30 is provided with a lever 310. The bolt 20 is provided with a lever engagement groove 220. The lever 310 is movably disposed within the lever engagement groove 220 and can abut against the groove wall of the lever engagement groove 220, thereby pushing the bolt 20 to move relative to the lock body 10. The electric drive assembly 40 is disposed within the lock body 10 and is kinetically connected to the rotating member 30.

[0033] The working principle of this window lock is based on the coordinated transmission of various components, which realizes the extension and retraction of the bolt to lock and open the window sash. The specific process is as follows:

[0034] When the window sash needs to be locked, the electric drive assembly starts and outputs power, forming a transmission connection with the rotating component, which in turn drives the rotating component to rotate within the lock body. The actuating lever on the rotating component rotates along with it. Because the actuating lever is movably positioned within the actuating groove of the latch, it gradually comes into contact with one side wall of the groove during rotation. As the rotating component continues to rotate, the actuating lever applies a pushing force to the latch through the groove wall, forcing the latch to move relative to the lock body towards the lock housing. Finally, the end of the latch extends into the keyhole on the lock housing, locking the window sash.

[0035] When the window needs to be opened, the electric drive assembly rotates in reverse, causing the rotating part to rotate in the opposite direction. At this time, the actuating lever abuts against the other side of the actuating groove wall, and pulls the bolt relative to the lock body in a direction away from the lock box through the groove wall, so that the bolt exits from the lock hole, thereby releasing the locked state and the window can be opened freely.

[0036] Throughout the process, the electric drive assembly provides the power source, and the rotating component converts the rotational motion of the electric drive assembly into the circular motion of the lever. Then, through the cooperation between the lever and the lever engagement groove, the circular motion is further converted into the linear reciprocating motion of the latch, thereby completing the locking and unlocking actions of the window lock.

[0037] See Figure 3 and Figure 4 The electric drive assembly 40 includes a drive motor 410, a drive gear 420, and a driven gear 430. The drive motor 410 is fixedly disposed inside the lock body 10, the drive gear 420 is fixedly disposed on the motor shaft of the drive motor 410, and the driven gear 430 is connected to the rotating member 30 and is driven by the drive gear 420.

[0038] See Figure 1The bolt 20 is disposed inside the lock body 10, and the wall surface of the lock body 10 facing the lock housing 60 has an opening 110. The bolt 20 is at least partially disposed within the opening 110 and can move through the opening 110 into the lock hole 600 to form a lock. The opening provides a movement channel for the bolt, ensuring that the bolt can pass through the opening and extend into the lock hole to complete the lock, while restricting the direction of movement of the bolt. Its guiding function improves the movement stability of the bolt.

[0039] See Figure 3 The latch 20 is provided with a guide groove 210, and the lock body 10 is connected with a guide member 120, which is inserted into the guide groove 210. In the mating structure of the latch 20 and the lock body 10, the guide member 120 is inserted into the guide groove 210 of the latch 20. In addition to guiding the latch 20 to move smoothly along a predetermined trajectory and avoiding deviation to ensure accurate insertion into the lock hole, the guide member 120 and the guide groove 210 can also effectively constrain the movement stroke of the latch 20. Specifically, the guide groove 210 is set along the movement direction of the latch 20, and the groove walls at both ends form physical limiting boundaries. When the latch 20 moves under the action of driving force, the guide member 120 will slide in the guide groove 210 with the movement of the latch 20 until the guide member 120 abuts against one end of the groove wall of the guide groove 210. At this time, the movement of the latch 20 is restricted and cannot continue to move in that direction.

[0040] See Figure 3 and Figure 4 The left and right sides of the actuating groove 220 are provided with positioning grooves 230, and the actuating rod 310 is inserted into or detached from the positioning groove 230.

[0041] See Figure 3 and Figure 4 The rotating component 30 is provided with a connecting component 320, which is connected to a compression spring 50. The other end of the compression spring 50 is connected to the lock body 10. During the left and right movement of the latch 20, when the latch moves to the right, it gradually approaches the locked position, and when it moves to the left, it gradually approaches the unlocked position. The compression spring 50 is an existing type of compression spring, selected according to different needs to apply different forces to the latch 20.

[0042] One embodiment of the compression spring uses an existing compression spring for applying a force to the latch 20, which is used to push the latch 20 to remain in the locked position.

[0043] In the second embodiment of the compression spring, an existing compression spring is used to apply two opposing forces to the latch 20. Specifically, when the latch 20 moves close to the locked position, the compression spring applies a pushing force to the right, pushing the latch 20 towards the locked position. The other force is a pulling force to the left when the latch 20 moves close to the unlocked position, pulling the latch 20 towards the unlocked position.

[0044] See Figure 2 The lock box 60 is detachably connected to a mounting pad 610. The detachable mounting pad 610 on the lock box 60 effectively improves the adaptability of the window lock to different window track profiles. Because different types and specifications of window track profiles vary in depth, if the lock box height is fixed, there may be a deviation in the relative position between the lock box and the bolt, causing the bolt to fail to accurately enter the keyhole to complete the locking. The mounting pad 610 can be flexibly added or removed according to the actual depth of the window track profile. By changing the overall height of the lock box, the relative position between the lock box and the bolt is adjusted, ensuring that the bolt maintains a precise correspondence with the keyhole during movement, thereby guaranteeing the reliability of the locking action and expanding the applicability of the window lock.

[0045] See Figure 1 The lock body 10 is equipped with a control switch 70, and a control circuit board is disposed within the lock body 10. The control switch 70 is electrically connected to the control circuit board, and the control circuit board is electrically connected to the electric drive assembly 40. The function of the control switch 70 is to allow the user to quickly press and hold the switch, which transmits a command to the electric drive assembly 40 via the control circuit board, directly locking or unlocking the window lock. The control switch 70 and the control circuit board utilize existing technology.

[0046] See Figure 1 The lock body 10 is rotatably equipped with a knob 80, which is connected to the rotating component 30. The function of the knob 80 is that the user can quickly and manually lock or unlock the window lock by rotating it, through the transmission with the rotating component 30.

[0047] In this invention, a control circuit board electrically connected to the electric drive assembly 40 is provided inside the lock body 10, and a sensor is connected to the control circuit board; a sensing element is provided in the lock box 60; when the sensor senses the sensing element, the sensor sends an electrical signal to the control circuit board, and the control circuit board controls the electric drive assembly 40 to drive the bolt 20 to extend into the lock hole 600. The purpose of this embodiment is that, based on the cooperation of the sensor and the sensing element, when the lock box 60 and the lock body 10 are in a preset position, the sensor is triggered by the sensing element and sends an electrical signal to the control circuit board. The control circuit board, based on this electrical signal, controls the electric drive assembly 40 to drive the bolt 20 to extend into the lock hole 600, thereby achieving the locking action.

[0048] Specifically, the sensor is a Hall sensor, and the sensing element is a magnet. Of course, other existing types of sensors and corresponding sensing elements can be used, as long as the lock body 10 moves with the window sash, and the sensor and sensing element are aligned at a preset position, the electric drive assembly 40 is activated via the control circuit board.

[0049] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
