Description

Technical Field

[0001] This invention relates to the field of window handles, and in particular to an automatically locking door and window handle. Background Technology

[0002] Currently, windows are generally equipped with window locks. Traditional window locks are divided into mechanical and key-operated types. Mechanical window locks mainly use a hook on the outside of the glass and a latch on the inside, with the latch and hook engaging to lock the window. Key-operated window locks are similar to mechanical locks, except that the latch in a key-operated window lock requires a key to operate, engaging and disengaging the latch and hook to lock or unlock. Although mechanical window locks are more convenient to use, they lack child protection features, posing a safety hazard. Furthermore, with key-operated window locks, many users tend to leave the key in the keyhole for extended periods, increasing the risk of children accidentally opening the window. Therefore, their safety performance is not high, and they pose a certain safety hazard.

[0003] Later, a window handle lock was invented that incorporates an identification module and a locking module inside the handle. The identification module recognizes and responds to unlocking and locking signals, while the locking module locks the handle based on these signals. This prevents the handle from being rotated and the window from being opened when no unlocking signal is detected, thus preventing unauthorized unlocking and providing safety features such as protection against falling objects in homes and offices. However, the existing window handle lock has a flawed design. Once authorized, the handle remains unlocked, allowing anyone to turn it at will. There is also the risk of children accidentally touching the handle, causing the window sash to fall off, resulting in poor safety.

[0004] Therefore, it is necessary to design a new technical solution to solve the above problems. Summary of the Invention

[0005] In view of this, the present invention addresses the deficiencies of the existing technology, and its main objective is to provide an automatically locking door and window handle. It utilizes a signal recognition device to identify the unlocking signal and authorize the drive device to control the unlocking of the locking device. In particular, it automatically locks within a preset time after unlocking, avoiding the problem of the handle assembly being rotated at will, preventing problems such as handle loosening and shaking, and has a wide range of applications.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An automatically locking door and window handle includes a mounting base and a handle assembly, wherein the handle assembly includes... A locking device forms a clutch structure with the fixed seat. When the locking device is locked with the fixed seat, it is in a locked mode, at which time the handle assembly is restricted from rotating relative to the fixed seat. When the locking device is unlocked from the fixed seat, it is in an unlocked mode, at which time the handle assembly can rotate relative to the fixed seat. A driving device drives the locking device to achieve locking and unlocking modes; A signal recognition device is used to identify unlocking signals; A control device, upon receiving an unlocking signal from a signal recognition device, controls a drive device to drive a locking device to achieve the unlocking mode, and within a preset time, controls the drive device to drive the locking device to automatically achieve the locking mode.

[0007] As a preferred embodiment, the signal identification device includes one or more of the following devices: a password signal identification device, a fingerprint identification device, a facial recognition device, or a wireless signal identification device.

[0008] As a preferred embodiment, the control device includes a circuit board, a main control chip, and a timing module. The timing module is integrated with the main control chip on the circuit board and is used to trigger timed tasks. After receiving the unlock signal from the signal recognition device, the main control chip controls the drive device to operate, thereby unlocking the locking device from the fixed base and completing the unlocking mode. The timing module triggers a timer after unlocking, and when the timer reaches the preset time, it sends feedback to the main control chip. After receiving the feedback from the timing module, the main control chip controls the drive device to operate, thereby locking the locking device from the fixed base and completing the locking mode.

[0009] As a preferred embodiment, the control device further includes a read-only memory and an erasable memory, wherein the read-only memory is used to store advanced account information that cannot be deleted, and the erasable memory is used to store ordinary account information that can be modified.

[0010] As a preferred embodiment, the handle assembly includes a gripping part and a connecting shaft connected together. The fixed base is provided with a first connecting hole that matches the connecting shaft. The handle assembly is rotatably connected to the first connecting hole of the fixed base through the connecting shaft. The fixed base is provided with a square shaft, and the connecting shaft is connected to the square shaft so that the square shaft rotates together with the handle assembly. The fixed base is provided with two or more locking holes arranged at intervals along the outer periphery of the first connecting hole. The locking device is movably mounted on the connecting shaft. The locking hole is located on one side of the locking device. A first elastic reset member is connected between the locking device and the connecting shaft. The driving device is mounted on the gripping part. The output end of the driving device is connected to a driving slider. The driving slider is located on the other side of the locking device. When unlocking, the drive device controls the drive slider to move in the first direction so that the drive slider moves away from the locking device. Under the action of the first elastic reset member, the locking device moves toward the gripping part to extend out of the locking hole and enter the connecting shaft to complete the unlocking mode, thereby realizing that the handle assembly can rotate in conjunction with the square shaft to rotate relative to the fixed seat. When locked, the drive device controls the drive slider to move in the second direction, so that the drive slider contacts the locking device, so that the locking device extends out of the connecting shaft and enters the locking hole to complete the locking mode, thereby locking the handle assembly to the fixed base and preventing the square shaft from rotating.

[0011] As a preferred embodiment, the locking device includes a locking post, a connecting edge is provided on the outer side of the locking post, the first elastic reset member is sleeved on the outer side of the locking post, and the two ends of the first elastic reset member act on the connecting shaft and the connecting edge respectively.

[0012] As a preferred embodiment, it further includes an auxiliary positioning block and a second elastic reset member. The auxiliary positioning block is movably mounted on the connecting shaft and located on one side of the locking device. The lower end of the auxiliary positioning block is slidably connected to the fixed seat and positioned in a restricted manner by the locking hole. The two ends of the second elastic reset member are respectively connected to the connecting shaft and the auxiliary positioning block. When the locking device enters one of the locking holes to complete the locking mode, the auxiliary positioning block matches and positions itself with the other locking hole.

[0013] As a preferred embodiment, four locking holes are provided, arranged in a ring array around the outer periphery of the first connecting hole.

[0014] As a preferred embodiment, the auxiliary positioning block has a spherical structure.

[0015] As a preferred embodiment, the end face of the drive slider near the locking device is provided with a drive ramp.

[0016] Compared with the prior art, the present invention has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution: Through the design of each component, a signal recognition device is used to identify the unlocking signal and authorize the drive device to control the unlocking of the locking device, preventing unauthorized personnel from unlocking the door. In particular, it will automatically lock after unlocking within a preset time, avoiding the security risks caused by users forgetting to lock the door, and also preventing the handle assembly from being turned by unauthorized personnel or in accidental situations, thus improving the safety of the handle assembly. Specifically, by achieving automatic locking in various positions of the window sash (such as rotating or tilting), it prevents unauthorized personnel or intruders from unlocking it from the outside when it is closed or tilted. At the same time, it prevents the window sash from falling off due to accidental operation (such as children turning the handle) when it is open. The core focus is on intrusion prevention and safety protection against accidental operation by children or others. It has excellent safety, meets the user's needs, and has a wide range of applications. Secondly, the multiple locking holes enable the handle assembly to be locked at multiple angles on the fixed base. Combined with the first elastic reset element, the locking device can extend out of the locking hole under the action of the first elastic reset element to achieve automatic unlocking and reset. At the same time, the driving slope facilitates the linkage contact between the locking device and the driving slider when unlocking or locking, thereby ensuring the stability and usability of the locking device. Furthermore, the auxiliary positioning block is positioned on another locking hole to form a two-point positioning and locking structure for the handle assembly in conjunction with the locking device. This reduces the operating load on the handle assembly, improves the durability and reliability of the locking device, and ensures the precision and smoothness of the handle assembly's rotation and locking action, making it highly practical.

[0020] Please refer to Figures 1 to 10 As shown, it illustrates the specific structure of an embodiment of the present invention.

[0021] An automatically locking door and window handle includes a mounting base 10 and a handle assembly 20, wherein the handle assembly 20 includes... A locking device 21 forms a clutch structure with the fixed seat. When the locking device is locked with the fixed seat, it is in a locked mode. At this time, the handle assembly is restricted from rotating relative to the fixed seat. When the locking device is unlocked from the fixed seat, it is in an unlocked mode. At this time, the handle assembly can rotate relative to the fixed seat. A driving device 22 drives the locking device to achieve locking and unlocking modes; A signal recognition device 23 is used to identify unlocking signals; A control device 24, after receiving the unlocking signal from the signal recognition device, controls the drive device to drive the locking device to achieve the unlocking mode, and controls the drive device to drive the locking device to automatically achieve the locking mode within a preset time. Specifically, the control device 24 includes a circuit board 241, a main control chip 242, and a timing module 243. The timing module 243 and the main control chip 242 are both integrated on the circuit board 241. The timing module 243 is used to trigger timed tasks. After receiving the unlocking signal from the signal recognition device 23, the main control chip 242 controls the drive device 22 to operate, so that the locking device 21 is unlocked from the fixed base 10, thereby completing the unlocking mode. The timing module 243 triggers a timer after unlocking. When the timer reaches the preset time, it feeds back to the main control chip 242. After receiving the feedback from the timing module 243, the main control chip 242 controls the drive device 22 to operate, so that the locking device 21 is locked from the fixed base 10, thereby completing the locking mode. In this embodiment, the signal recognition device 23 includes one or more of the following devices: a password signal recognition device, a fingerprint recognition device, a face recognition device, or a wireless signal recognition device. Preferably, the control device 24 is provided with a green light 246 for indicating successful operation, a red light 247 for indicating failed operation, and a buzzer 248 for emitting an audible prompt. The green light 246, red light 247, and buzzer 248 are all provided on the circuit board 241 of the control device 24. The control device 24 is connected to a power source located inside the handle assembly 20. The control device 24 is provided with a charging interface that protrudes outside the handle assembly 20. like Figure 6 As shown, it illustrates the fingerprint or card unlocking process of the present invention. During the unlocking process, when the signal recognition device 23 recognizes the correct unlocking signal, it feeds back to the control device 24, the green light 246 turns on, the buzzer 248 sounds, and at the same time, the drive device 22 runs and controls the locking device 21 to unlock the fixed base 10, thereby completing the unlocking mode. In addition, the timing module 243 triggers a timer after unlocking. When the timing time of the timing module 243 reaches the preset time, the main control chip 242 controls the drive device 22 to run after receiving feedback from the timing module 243, so that the locking device 21 and the fixed base 10 enter the locking mode, thereby completing the locking mode. When the signal recognition device 23 detects an incorrect unlocking signal or fails to receive the unlocking signal, it feeds the information back to the control device 24. The red light 247 turns on, the buzzer 248 sounds, and the drive device 22 does not run. It should be noted that the timing module 243 triggers a timing period of 5 seconds. This timing period is not limited to 5 seconds and can be set according to the user's actual usage. Furthermore, the door and window handles in this invention are applicable to scenarios such as public buildings, schools, and government agencies. For example, the advanced account information is the mastercard, which is applicable to administrators or property management personnel of agencies / schools. The standard account information is a user card: applicable to authorized personnel; it can also be used as a temporary card for window cleaners, etc. Fingerprint recognition: suitable for multiple authorized personnel in private residences or public buildings, such as teachers, kindergarten staff, office workers, etc. Example of a public building scenario: Property management personnel / administrators: Authorize individual and user cards through the main card; Staff in public buildings: Access is granted via fingerprint recognition; Window cleaners or external company personnel who need window maintenance: Temporary user cards will be issued by the administrator, with the authorization period matching the maintenance work cycle.

[0022] Thus, through the design of each component, a signal recognition device identifies the unlocking signal and authorizes the drive device to control the unlocking of the locking device, preventing unauthorized personnel from unlocking the door. In particular, it automatically locks within a preset time after unlocking, avoiding the security risks caused by users forgetting to lock the door, and also preventing the handle assembly from being turned by unauthorized personnel or in accidental situations, thus improving the safety of the handle assembly. Specifically, by automatically locking in various positions of the window sash (such as in the rotating or tilted state), it prevents unauthorized personnel or intruders from unlocking it from the outside when it is closed or tilted. At the same time, it prevents the window sash from falling off due to accidental operation (such as children turning the handle) when it is open. The core focus is on intrusion prevention and safety protection against accidental operation by children or others, providing excellent security, meeting user needs, and having a wide range of applications.

[0023] Furthermore, the handle assembly 20 includes a gripping part 25 and a connecting shaft 26 connected together. The fixed base 10 is provided with a first connecting hole 11 that matches the connecting shaft. The handle assembly 20 is rotatably connected to the first connecting hole 11 of the fixed base 10 through the connecting shaft 26. The fixed base 10 is provided with a square shaft 12. The connecting shaft 26 is connected to the square shaft 12 so that the square shaft 12 rotates together with the handle assembly 20. The fixed base 10 is provided with two or more locking holes 13 arranged at intervals along the outer periphery of the first connecting hole. The locking device 21 is movably disposed on the connecting shaft 26. The locking holes 13 are located on the lower side of the locking device 21. A first elastic reset member 261 is connected between the locking device 21 and the connecting shaft 26. The driving device 22 is disposed on the gripping part 25. The output end of the driving device 22 is connected to a driving slider 221. The driving slider 221 is located on the upper side of the locking device 21. When unlocking, after the signal recognition device 23 recognizes the correct unlocking signal, it feeds back to the control device 24. The drive device 22 controls the drive slider 221 to move in the first direction so that the drive slider 221 moves away from the locking device 21. Under the action of the first elastic reset member 261, the locking device 21 moves toward the grip part 25 to extend out of the locking hole 13 and enter the connecting shaft 26 to complete the unlocking mode, thereby realizing that the handle assembly 20 can rotate in conjunction with the square shaft 12 to rotate relative to the fixed seat 10 while rotating. When locked, the timing module 243 triggers a timer after unlocking. When the timer of the timing module 243 reaches the preset time, the main control chip 242 controls the drive device 22 to run after receiving feedback from the timing module 243. The drive device 22 controls the drive slider 221 to move in the second direction, so that the drive slider 221 contacts the locking device 21, so that the locking device 21 extends out of the connecting shaft 26 and enters the locking hole 13 to complete the locking mode, thereby realizing that the handle assembly 20 is locked to the fixed base 10 and cannot drive the square shaft 12 to rotate. The following are examples of security performance scenarios: 1. When the windows are closed, the door and window handles are locked to prevent the handles from being pried open and thus prevent the windows from being opened illegally; 2. When the door and window handles are in unlock mode, they control the windows to open and be in an upward-hung state. When the preset time is reached, the door and window handles will switch to lock mode to prevent the handles from being turned by hooks, lassos or other tools from the outside, thus preventing the windows from being illegally opened. 3. When the window is open, the door and window handles are in locked mode. The door and window handles cannot be switched to the top-hung position and will not fall out of the mechanical structure, which can effectively prevent children from operating them accidentally.

[0024] Specifically, the locking device 21 includes a locking post 211, with a connecting edge 212 on the outer side of the locking post 211. The first elastic reset member 261 is sleeved on the outer side of the locking post 211. A first mounting cavity 262, which extends vertically, is provided inside the connecting shaft 26. The locking post 211 and the first elastic reset member 261 are both located on the first mounting cavity 262. The two ends of the first elastic reset member 261 act on the first mounting cavity 262 and the connecting edge 212, respectively. A driving inclined surface 222 is provided on the end face of the driving slider 221 near the locking device. Thus, the multiple locking holes enable the handle assembly to be locked at multiple angles on the fixed base. Combined with the first elastic reset member, the locking device can extend out of the locking hole under the action of the first elastic reset member to achieve automatic unlocking and reset. At the same time, the driving inclined surface facilitates the linkage contact between the locking device and the driving slider when unlocking or locking, thereby ensuring the stability and usability of the locking device.

[0025] It also includes an auxiliary positioning block 27 and a second elastic reset member 271. The auxiliary positioning block 27 is movably disposed on the connecting shaft 26 and located on one side of the locking device 21. The lower end of the auxiliary positioning block 27 is slidably connected to the fixed base 10 and is restricted and positioned by the locking hole 13. The two ends of the second elastic reset member 271 are respectively connected to the connecting shaft 26 and the auxiliary positioning block 27. Specifically, the connecting shaft 26 has a second mounting cavity 263 with an open lower end. The auxiliary positioning block 27 and the second elastic reset member 271 are both disposed in the second mounting cavity 263. The lower end of the auxiliary positioning block 27 passes through the lower opening and protrudes outside the second mounting cavity 263. The upper end of the second elastic reset member 271 is connected to the upper end surface of the second mounting cavity 263, and the lower end of the second elastic reset member 271 is connected to the upper end of the auxiliary positioning block 27. Preferably, the auxiliary positioning block 27 has a spherical structure. When the locking device 21 enters one of the locking holes 13 and completes the locking mode, the auxiliary positioning block 27 matches and positions itself with the other locking hole 13. Thus, the auxiliary positioning block is positioned on the other locking hole to form a two-point positioning and locking structure for the handle assembly in conjunction with the locking device. This reduces the operating load on the handle assembly, improves the durability and reliability of the locking device, and ensures the accuracy and smoothness of the rotation and locking action of the handle assembly, making it highly practical.

[0026] Furthermore, four locking holes 13 are provided, arranged in a circular array around the outer periphery of the first connecting hole 11; at least one auxiliary positioning block 27 is provided. When there is one auxiliary positioning block 27, it is positioned opposite to the locking device 21 on both sides of the connecting shaft 26, or the auxiliary positioning block 27 is positioned beside the locking device 21, with an included angle of 90 degrees between the auxiliary positioning block 27 and the locking device 21; when there are two auxiliary positioning blocks 27, they are positioned opposite to each other on both sides of the connecting shaft 26, with the locking device 21 located between the two auxiliary positioning blocks 27. It should be noted that users can choose to use one or two auxiliary positioning blocks, or use the locking device without auxiliary positioning blocks, depending on the usage environment of the product.

[0027] Furthermore, a second connecting hole 264 is provided on the connecting shaft 26. The first mounting cavity 262 and the second mounting cavity 263 are located around the second connecting hole 264. The upper end of the square shaft 12 is movably connected to the second connecting hole 264. A third elastic reset member 265 is provided in the second connecting hole 264. The two ends of the third elastic reset member 265 are respectively connected to the second connecting hole 264 and the square shaft 12, so that the square shaft 12 moves downward under the action of the third elastic reset member 265 and passes through the first connecting hole 11 and extends into the mounting hole of the door and window. Preferably, the first elastic reset member 261, the second elastic reset member 271 and the third elastic reset member 265 are all springs.

[0028] Furthermore, the control device 24 also includes a read-only memory 244 and an erasable memory 245, which are integrated on the circuit board. The read-only memory 244 is used to store advanced account information that cannot be deleted, and the erasable memory 245 is used to store ordinary account information that can be modified. Preferably, the control device 24 is also provided with a blue light 249 for displaying that the information registration operation is turned on. like Figures 7 to 8 As shown, Figure 7 The process of registering and recording the card into the erasable memory of the present invention is shown. Before registration, the advanced account information is first identified by the signal recognition device 23 and fed back to the control device 24. When the identified advanced account information matches the advanced account information in the read-only memory 244, the blue light 249 turns on and the buzzer 248 sounds. Then, the card with the new ordinary account information is identified by the signal recognition device 23. The signal recognition device 23 identifies the card with the new ordinary account information and feeds it back to the control device 24, and stores the identification information of the card with the new ordinary account information into the erasable memory 245. After successful storage, the green light 246 turns on, the buzzer 248 sounds, and the registration operation ends. Furthermore, when the identification information of the card with the new ordinary account information already exists in the erasable memory 245, the red light 247 turns on and the buzzer 248 sounds to remind the user that the card with the ordinary account information has been registered. Figure 8The process of fingerprint registration and recording into the erasable memory is shown. First, the advanced account information is identified by the signal recognition device 23 and fed back to the control device 24. When the identified advanced account information matches the advanced account information in the read-only memory 244, the blue light 249 turns on and the buzzer 248 sounds. Then, the new user touches the finger to be recorded with the signal recognition device 23 multiple times so that the signal recognition device 23 can collect the new user's fingerprint. When the new user's fingerprint is collected, the green light 246 turns on, the buzzer 248 sounds, and the registration operation ends. When the new user's fingerprint information already exists in the erasable memory 245, the red light 247 turns on and the buzzer 248 sounds twice to remind the registered user that the fingerprint information has been registered. At the same time, when the new user's fingerprint area is large, the red light 247 turns on and the buzzer 248 sounds once to remind the user that the fingerprint collection failed and to re-collect the fingerprint.

[0029] When the signal recognition device 23 identifies incorrect advanced account information or fails to receive advanced account information, the red light 247 turns on, the buzzer 248 sounds, and the operation ends.

[0030] The key design feature of this invention lies in its design of various components. It utilizes a signal recognition device to identify unlocking signals and authorizes the driving device to control the locking mechanism, preventing unauthorized unlocking. Specifically, it automatically locks within a preset time after unlocking, avoiding security risks caused by users forgetting to lock and preventing unauthorized personnel or accidental manipulation of the handle assembly. This prevents handle loosening and wobbling, improving the stability and safety of the handle assembly. Specifically, it automatically locks the window sash in various positions (e.g., rotating or tilted), preventing unauthorized personnel or intruders from unlocking it from the outside when closed or tilted. Simultaneously, it prevents the window sash from falling due to accidental operation (e.g., children turning the handle) when open. The core focus is on intrusion prevention and safety, as well as preventing accidental operation by children or others. It offers excellent safety, meets user needs, and has a wide range of applications. Secondly, the multiple locking holes enable the handle assembly to be locked at multiple angles on the fixed base. Combined with the first elastic reset element, the locking device can extend out of the locking hole under the action of the first elastic reset element to achieve automatic unlocking and reset. At the same time, the driving slope facilitates the linkage contact between the locking device and the driving slider when unlocking or locking, thereby ensuring the stability and usability of the locking device. Furthermore, the auxiliary positioning block is positioned on another locking hole to form a two-point positioning and locking structure for the handle assembly in conjunction with the locking device. This reduces the operating load on the handle assembly, improves the durability and reliability of the locking device, and ensures the precision and smoothness of the handle assembly's rotation and locking action, making it highly practical.

[0031] The above description is merely a preferred embodiment of the present invention and does not constitute any limitation on the technical scope of the present invention. Therefore, any minor modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention shall still fall within the scope of the technical solution of the present invention.

The timing module triggers a timer after unlocking, and when the timer reaches the preset time, it sends feedback to the main control chip. After receiving the feedback from the timing module, the main control chip controls the drive device to operate, thereby locking the locking device from the fixed base and completing the locking mode.

4. The automatically locking door and window handle according to claim 1, characterized in that: The control device also includes a read-only memory and an erasable memory. The read-only memory is used to store advanced account information that cannot be deleted, and the erasable memory is used to store ordinary account information that can be modified.

5. The automatically locking door and window handle according to claim 1, characterized in that: The handle assembly includes a gripping part and a connecting shaft connected together. The fixed base is provided with a first connecting hole that matches the connecting shaft. The handle assembly is rotatably connected to the first connecting hole of the fixed base through the connecting shaft. The fixed base is provided with a square shaft. The connecting shaft is connected to the square shaft so that the square shaft rotates together with the handle assembly. The fixed base is provided with two or more locking holes arranged at intervals along the outer periphery of the first connecting hole. The locking device is movably mounted on the connecting shaft. The locking hole is located on one side of the locking device. A first elastic reset member is connected between the locking device and the connecting shaft. The driving device is mounted on the gripping part. The output end of the driving device is connected to a driving slider. The driving slider is located on the other side of the locking device. When unlocking, the drive device controls the drive slider to move in the first direction so that the drive slider moves away from the locking device. Under the action of the first elastic reset member, the locking device moves toward the gripping part to extend out of the locking hole and enter the connecting shaft to complete the unlocking mode, thereby realizing that the handle assembly can rotate in conjunction with the square shaft to rotate relative to the fixed seat. When locked, the drive device controls the drive slider to move in the second direction, so that the drive slider contacts the locking device, so that the locking device extends out of the connecting shaft and enters the locking hole to complete the locking mode, thereby locking the handle assembly to the fixed base and preventing the square shaft from rotating.
