Description

Technical Field

[0001] This invention relates to the field of child safety gate technology, and in particular to an automatic reset baby fence safety gate with opening and closing monitoring. Background Technology

[0002] With the continuous upgrading of parenting concepts, parents are paying more and more attention to the safety of infants and young children at home. As a core protective device to ensure the safety of infants and young children in a limited area, the market demand for baby playpens continues to grow. Among them, baby playpens with passage function and protective gates have become an important part of playpens products.

[0003] Most baby playpens and safety gates on the market currently only have basic isolation and protection functions. In actual use, they have gradually revealed many technical defects that urgently need to be addressed, as follows: Firstly, they lack reliable automatic reset capabilities. Traditional baby playpen safety gates are mostly manually operated. When parents are holding infants or moving items, their hands are often occupied and they cannot close the safety gate in time, resulting in the safety gate remaining open for a long time. Infants can easily climb out of the playpen area through the opening, thus facing safety hazards such as bumps, falls, etc.

[0004] Secondly, there is a lack of monitoring methods for the locking status. Most existing safety doors use mechanical latches, relying solely on parents' visual inspection to determine if the door is properly locked. This lack of automated and precise monitoring of the locking status means that parents may inadvertently leave the door partially unlocked without realizing it, while infants or toddlers may accidentally activate the unlocking mechanism and open the door while playing.

[0005] In summary, existing baby fence safety gates suffer from a lack of reliable automatic reset capability and a lack of means to monitor the locking status. Summary of the Invention

[0006] This invention provides an automatic reset baby fence safety gate with opening and closing monitoring, which can solve the problems of existing baby fence safety gates lacking reliable automatic reset capability and lacking locking status monitoring methods.

[0007] An automatic reset baby fence safety gate with opening and closing monitoring, comprising: Door frame; A door body, which is rotatably mounted on a door frame; An automatic reset mechanism is provided at the rotational connection between the door body and the door frame. The automatic reset mechanism is used to drive the door body to automatically rotate back to the closed initial position after the door body is opened. A locking monitoring component includes a latch body, a channel plate, and a U-shaped sensor. A first sliding groove is provided on the door body, and the latch body is slidably disposed in the first sliding groove. A first groove for accommodating the latch body is also provided on the door frame. The channel plate is located on the main body of the latch, and the U-shaped sensor is located inside the door. The channel plate has a channel notch. When the main body of the latch slides in the first groove, the channel notch on the channel plate moves synchronously with the main body of the latch to block or conduct the light path of the U-shaped sensor.

[0008] This invention provides an automatic reset baby fence safety gate with opening and closing monitoring, which has, but is not limited to, the following beneficial effects compared to the prior art: In this automatic reset baby fence safety gate with opening and closing monitoring, the door frame serves as the supporting foundation for the entire safety gate. Its overall structure must possess sufficient strength and stability to withstand the rotation of the door and the impact of external forces from infants and young children. It is typically made of high-strength plastic or metal. The door itself, as the core passage component of the safety gate, is connected to the door frame via hinges, pivots, or other hinged structures, ensuring the door can flexibly open and close around the connection point to meet the passage needs of parents and infants. Furthermore, an automatic reset mechanism is installed at the rotational connection between the door and the door frame. Its core function is to automatically drive the door back to its initial closed position after it has been manually or accidentally opened, preventing the safety gate from being left open for extended periods and creating safety hazards.

[0009] The locking monitoring component is the core component for accurately monitoring the locking status of the security door. The latch body, acting as the actuator of the locking structure, slides linearly within the first groove. When the door rotates to the closed position, the latch body slides into the first groove on the door frame, achieving mechanical locking between the door and the frame. When the security door needs to be opened, external force can drive the latch body to slide out of the first groove along the first groove, releasing the locking state. The channel plate is fixedly connected to the latch body and slides synchronously with it. The U-shaped sensor, as a non-contact monitoring element, has an internal transmitter and receiver to form a stable optical path. Movement of the channel notch on the channel plate blocks or opens the optical path, thus providing feedback on the position of the latch body.

[0010] This invention provides an automatically resetting baby fence safety gate with opening and closing monitoring. Through a combination of mechanical locking and non-contact optical path monitoring, along with an automatic reset mechanism, it specifically addresses the technical pain points of traditional baby fence safety gates, such as lack of automatic reset capability and inaccurate monitoring of the locking status. The core idea is to link the sliding movement of the locking tongue with the on / off state of the optical path of the U-shaped sensor, achieving real-time automated monitoring of the locking status. Simultaneously, the automatic reset mechanism ensures that the gate automatically closes after being opened, improving the safety and reliability of the safety gate from both mechanical structure and monitoring logic perspectives. The non-contact optical path monitoring avoids monitoring failures caused by component wear, while the automatic reset mechanism eliminates the safety hazard of the safety gate being left open by the user.

[0011] Furthermore, the automatic reset baby fence safety gate with opening and closing monitoring also includes an alarm and a controller, the controller being electrically connected to the alarm and the U-shaped sensor respectively; The controller is used to receive the optical path on / off signal from the U-shaped sensor and control the alarm to issue a warning based on the signal status of the optical path on / off signal.

[0012] Furthermore, the bottom of the door frame is provided with anti-slip pads.

[0013] Furthermore, the door frame is U-shaped, and the door body is rotatably disposed within the opening end of the door frame.

[0014] Furthermore, a stop strip is provided on the inner side of the door frame.

[0015] Furthermore, a protrusion is provided on the left side of the door body, and a second groove is provided on the door frame corresponding to the position of the protrusion. Mounting grooves are provided at the top and bottom of the protrusion. The automatic reset mechanism is provided in two parts, and the two automatic reset mechanisms are respectively located in two mounting slots.

[0016] Furthermore, the automatic reset mechanism includes a first mating component and a reset assembly, the first mating component and the reset assembly being respectively disposed on the door frame and the door body; The first mating component has a first inclined surface; The reset assembly includes a mounting housing, a second mating component, an elastic reset component, and an elastic support component, wherein the second mating component, the elastic reset component, and the elastic support component are all disposed within the mounting housing; One end of the elastic reset member is connected to the second mating member, and the other end of the elastic reset member is connected to the elastic support member; The second mating component has a hollow structure. An inclined groove is provided at the end of the second mating component away from the elastic support. The inclined groove has a second inclined surface that matches the first inclined surface. The automatic reset baby fence with opening and closing monitoring has an open state and a closed state. In the closed state, the first ramp surface abuts against the second ramp surface. During the transition from the closed state to the open state, the door body rotates and opens relative to the door frame, and the first ramp surface presses against the second ramp surface to push the second mating component to overcome the elastic force of the elastic reset component and move away from the first mating component. During the transition from the open state to the closed state, the elastic force of the elastic reset member drives the second mating member to move toward the first mating member, causing the door to rotate and close relative to the door frame.

[0017] Furthermore, the second groove is provided with guide posts at the top and bottom, and the mounting housing is provided with mounting holes that cooperate with the guide posts.

[0018] Furthermore, the elastic reset element is a rubber elastomer or a spring.

[0019] Furthermore, a third groove is provided on the rear side of the door body, a lock tongue shell is provided in the third groove, and an unlocking component is provided in the lock tongue shell. The unlocking component is used to drive the lock tongue body to move. The U-shaped sensor is located inside the latch housing. Attached Figure Description

[0028] like Figures 1 to 2 As shown in the figure, an embodiment of the present invention provides an automatic reset baby fence safety gate with opening and closing monitoring, comprising: Door frame 1; Door 2 is rotatably mounted on door frame 1; Automatic reset mechanism 4 is located at the rotational connection between door body 2 and door frame 1. Automatic reset mechanism 4 is used to drive door body 2 to automatically rotate back to the closed initial position after door body 2 is opened. Locking monitoring component 3 includes a latch body 31, a channel plate 32 and a U-shaped sensor 33. A first sliding groove 21 is provided on the door body 2, and the latch body 31 is slidably disposed in the first sliding groove 21. A first groove 11 for accommodating the latch body 31 is also provided on the door frame 1. The channel plate 32 is located on the latch body 31, the U-shaped sensor 33 is located inside the door body 2, and the channel plate 32 has a channel notch 34. When the latch body 31 slides in the first slide groove 21, the channel notch 34 on the channel plate 32 moves synchronously with the latch body 31 to block or conduct the light path of the U-shaped sensor 33.

[0029] In practical applications, the door frame 1 serves as the supporting foundation for the entire protective door. Its overall structure must possess sufficient strength and stability to withstand the rotation of the door body 2 and the impact of external forces from infants and young children. It is typically made of high-strength plastic or metal. The door body 2, as the core passage component of the protective door, is connected to the door frame 1 via hinges, pivots, or other hinged structures, ensuring that the door body 2 can flexibly open and close around the connection point to meet the passage needs of parents and infants. Furthermore, an automatic reset mechanism 4 is installed at the rotational connection between the door body 2 and the door frame 1. Its core function is to automatically drive the door body 2 back to its initial closed position after it has been opened manually or accidentally, preventing the protective door from being left open for extended periods and creating safety hazards.

[0030] The locking monitoring component 3 is the core component for accurately monitoring the locking status of the protective door. The latch body 31, acting as the actuator of the locking structure, can slide linearly within the first slide groove 21. When the door 2 rotates to the closed position, the latch body 31 slides into the first groove 11 on the door frame 1, achieving mechanical locking between the door 2 and the door frame 1. When the protective door needs to be opened, external force can drive the latch body 31 to slide out of the first groove 11 along the first slide groove 21, releasing the locking state. The channel plate 32 is fixedly connected to the latch body 31 and can slide synchronously with it. The U-shaped sensor 33, as a non-contact monitoring element, has an internal transmitter and receiver to form a stable optical path. The movement of the channel notch 34 on the channel plate 32 blocks or opens the optical path, thereby providing feedback on the position status of the latch body 31.

[0031] As a preferred embodiment, the rotating connection between the door frame 1 and the door body 2 can be made using a stainless steel pivot. This pivot must be rust-proof and wear-resistant, and the fit clearance between the pivot and the connection part must be precisely controlled to ensure the flexibility of the door body 2's rotation while avoiding loosening or shaking. The inner wall of the first slide groove 21 can be provided with a wear-resistant coating or wear-resistant pads to reduce frictional loss during the sliding process of the latch body 31 and extend its service life. The U-shaped sensor 33 can be a modulated light slot photoelectric sensor, with its transmitter and receiver located on both sides of the U-shaped opening. It has the advantages of fast response speed, high monitoring accuracy, and strong anti-interference ability, and can adapt to the complex home use environment of baby fence safety gates.

[0032] The innovation of this application lies in its combined design of "mechanical locking + non-contact optical path monitoring," along with an automatic reset mechanism, specifically addressing the technical pain points of traditional baby fence safety gates that lack automatic reset capability and cannot accurately monitor the locking status. The core idea is to link the sliding motion of the latch body with the on / off state of the optical path of the U-shaped sensor, achieving real-time automated monitoring of the locking status. Simultaneously, the automatic reset mechanism ensures that the gate automatically closes after being opened, improving the safety and reliability of the safety gate from both mechanical structure and monitoring logic perspectives. This non-contact optical path monitoring avoids monitoring failures caused by component wear, while the automatic reset mechanism eliminates the safety hazard of the safety gate being left open by the user.

[0033] The working principle of this embodiment is as follows: The protective door achieves accurate feedback on its automatic closing and locking status through the reset drive of the automatic reset mechanism and the optical path monitoring of the locking monitoring component. Specifically, when a parent or infant pushes the door 2 to open it around the rotating connection of the door frame 1, the automatic reset mechanism 4 stores reset potential energy as the door 2 rotates. After the external force disappears, the automatic reset mechanism 4 releases the potential energy, driving the door 2 to rotate back to the initial closed position. During the closing process of the door 2, the latch body 31 can slide in the first slide groove 21 and embed into the first groove 11 of the door frame 1 to complete the mechanical locking. If the protective door needs to be opened, the external force drives the latch body 31 to move away from the first groove 11 along the first slide groove 21. At this time, the channel plate 32 connected synchronously with the latch body 31 also moves. The channel notch 34 on the channel plate 32 will change its relative position with the U-shaped sensor 33: when the latch body 31 is fully embedded in the first groove 11 to achieve locking, the channel notch 34 is exactly between the light paths of the U-shaped sensor 33, the light path is open, and the feedback indicates that the protective door has been locked. When the latch body 31 slides out of the first groove 11 to release the locking, the solid part of the channel plate 32 will block the light path of the U-shaped sensor 33, the light path is broken, and the feedback indicates that the protective door has not been locked. Therefore, the locking and unlocking monitoring component can monitor the locking and unlocking status of the protective door in real time by changing the on and off of the optical path, while the automatic reset mechanism ensures that the door can automatically return to its original position after being opened. The two work together to form a double security protection, eliminating the security loopholes of traditional protective doors.

[0034] like Figures 1 to 3 As shown, in some embodiments of the present invention, the automatic reset baby fence safety gate with opening and closing monitoring also includes an alarm 5 and a controller, the controller being electrically connected to the alarm 5 and the U-shaped sensor 33 respectively. The controller is used to receive the optical path on / off signal from the U-shaped sensor 33, and to control the alarm 5 to issue a warning based on the signal status of the optical path on / off signal.

[0035] Specifically, the controller refers to an intelligent control device capable of receiving sensor signals, performing logical judgments, and outputting control commands. It can be implemented using hardware architectures such as microcontrollers, PLCs (Programmable Logic Controllers), and embedded microcontrollers, and has built-in preset signal processing and control logic programs, enabling rapid response to input signals and command issuance. The alarm 5 refers to a warning execution component capable of emitting audible and visual warning information. It can take the form of a buzzer, LED audible and visual alarm, or voice alarm, and can implement different modes of warning reminders according to the controller's instructions. The U-shaped sensor 33 serves as the signal acquisition end, and its circuit connection to the controller can use wired wiring or low-power wireless communication to ensure stable and real-time transmission of the optical path on / off signal to the controller.

[0036] In detail, in the aforementioned automatic reset baby fence safety gate with opening and closing monitoring, an alarm 5 and a controller are installed, forming a complete locking status early warning control system with the original U-shaped sensor 33, realizing closed-loop protection from status monitoring to safety early warning. When the safety gate is in the normal locked state, the latch body 31 is normally embedded in the first groove 11 of the door frame 1, and the channel notch 34 on the channel plate 32 is exactly between the optical paths of the U-shaped sensor 33, keeping the optical path open. The U-shaped sensor 33 transmits an optical path open signal to the controller. After receiving the signal, the controller determines that the safety gate is locked in place and does not trigger the alarm 5. When the safety gate is opened, the latch body 31 slides out of the first groove 11, and the solid part of the channel plate 32 blocks the optical path of the U-shaped sensor 33, breaking the optical path. The U-shaped sensor 33 transmits an optical path break signal to the controller. Based on the preset control logic, the controller determines that the safety gate is in an unsafe state and then sends a warning command to the alarm 5, driving the alarm 5 to activate the early warning.

[0037] Furthermore, by introducing intelligent control and early warning mechanisms, this solution not only solves the technical problems of traditional baby fence safety gates that can only monitor but not warn, and parents are unable to promptly notice abnormal locking, but also significantly improves the safety protection level and intelligence level of the safety gate. The controller can preset different early warning trigger logics. For example, when the light path disconnection signal lasts for more than a preset time (such as 3 seconds), the alarm 5 will be activated to avoid false alarms caused by brief operations. At the same time, the multi-mode warning design of the alarm 5 can be adapted to different home environments. For example, at night, the light warning is prioritized to avoid noise interference, and during the day, the sound and light synchronous warning is activated to ensure that parents can quickly notice. Thus, the safety gate is upgraded from passive protection to active early warning, providing comprehensive protection for the safety of infants and young children at home.

[0038] like Figures 1 to 3 As shown, in some embodiments of the present invention, the bottom of the door frame 1 is provided with an anti-slip pad 13. The anti-slip pad 13 refers to a protective buffer component installed at the bottom of the door frame 1 to enhance the friction between the door frame 1 and the ground. It can be made of elastic anti-slip materials such as silicone, natural rubber, anti-slip EVA foam, or wear-resistant polyurethane. Some anti-slip pads 13 can also be designed as detachable structures for easy replacement and maintenance. The bottom surface of the anti-slip pad 13 can be provided with anti-slip patterns, such as diamond patterns, cross patterns, or dotted protrusions, to further improve the adhesion and friction with the ground. The door frame 1 is the main supporting body of the protective door, and its bottom has a pre-reserved installation position adapted to the anti-slip pad 13. The anti-slip pad 13 can be fixedly installed through integral injection molding, strong adhesive, or snap-fit ​​connection, ensuring that the anti-slip pad 13 is not easily detached during use.

[0039] In the above-mentioned automatic reset baby fence safety gate with opening and closing monitoring, a stable connection structure between the safety gate and the ground is constructed by setting anti-slip pads 13 at the bottom of the door frame 1, which effectively solves the problem that traditional baby fence safety gates are prone to displacement due to external forces.

[0040] like Figures 1 to 3 As shown, in some embodiments of the present invention, the door frame 1 is U-shaped, and the door body 2 is rotatably disposed within the opening end of the door frame 1.

[0041] Specifically, the U-shaped door frame 1 refers to a support frame that is U-shaped in overall shape. It is composed of two vertical support sections on both sides and a horizontal connecting section at the bottom, which are integrally formed or spliced ​​together. It can be made of high-strength ABS engineering plastic, aluminum alloy profiles, or carbon steel, etc., combining structural stability and lightweight characteristics. The opening end of the door frame 1 is the open side of the U-shaped structure. One of the vertical support sections has a reserved door rotation connection position on the inner side. It can be rotated and connected to the door body 2 through hinge components such as stainless steel pivots and damping hinges, ensuring the smoothness and stability of the door body 2 during rotation. The door body 2 is a plate-shaped or grid-shaped protective component adapted to the size of the opening end of the U-shaped door frame 1. Its width matches the spacing of the opening end of the door frame 1. It can adopt an integrated grid structure of the same material as the door frame 1, which not only ensures protective safety but also maintains the uniformity of the overall appearance. Some door bodies 2 can also be equipped with transparent protective panels to facilitate parents to observe the status of infants and toddlers inside the enclosure in real time.

[0042] In detail, the aforementioned automatic reset baby fence safety gate with opening and closing monitoring, by designing the door frame 1 as a U-shaped structure and setting a rotatable door body 2 at the open end, an integrated protection and passage structure adapted to the baby fence system is constructed, effectively solving the technical problem that traditional straight door frame safety gates are difficult to splice with fence components to form a closed area. The bottom horizontal connecting section of the U-shaped door frame 1 can directly contact the ground, and the vertical support sections on both sides can be spliced ​​with other standard baby fence components to quickly form a closed protective area for infants and toddlers; while setting the door body 2 inside the open end of the U-shaped door frame 1 not only preserves the integrity of the protective area but also achieves convenient passage. The rotation range of the door body 2 is limited by the open end of the U-shaped door frame 1, preventing excessive rotation and interference with other fence components. Meanwhile, the U-shaped door frame 1 has natural mechanical stability. Its vertical support sections on both sides can evenly distribute the backlash force generated when the door 2 automatically resets, avoiding excessive local stress on the door frame and deformation, ensuring the structural strength of the protective door for long-term use. In addition, the symmetrical design of the opening end can make the rotation trajectory of the door 2 more regular, further improving the accuracy of automatic reset.

[0043] like Figures 1 to 3 As shown, in some embodiments of the present invention, a stop strip 12 is provided on the inner side of the door frame 1.

[0044] Specifically, the stop strip 12 refers to the protective component installed on the inside of the door frame 1 to limit the closing position of the door and buffer impact. It can be made of materials with high toughness and buffering properties such as food-grade silicone, soft rubber, and elastic PVC. Some stop strips 12 can be designed as porous buffer structures or surface anti-slip texture structures to improve protection and compatibility. The stop strip 12 is long and strip-shaped, and its length matches the length of the protective area inside the door frame 1. It can be fixed to the inside of the door frame 1 by means of one-piece injection molding, strong traceless adhesive, snap-fit ​​embedded connection, etc., especially the inner edge of the opening end of the U-shaped door frame 1, to ensure that it can accurately contact the edge of the door 2 when the door 2 is closed, and will not protrude from the outside of the door frame 1 after installation, affecting the overall splicing compatibility.

[0045] When the automatic reset mechanism 4 drives the door 2 to rotate to the closed position, the edge of the door 2 will first contact the stop strip 12. The elastic material of the stop strip 12 can buffer the impact force generated by the door 2 resetting, greatly reducing the noise of the door colliding with the door frame and improving the quietness of home use. At the same time, the stop strip 12 can accurately limit the final closed position of the door 2, avoiding the door 2 from over-rotating or deviating due to excessive reset force, ensuring that the latch body 31 can be accurately aligned with the first groove 11 on the door frame 1, and ensuring the stable triggering of the locking structure.

[0046] like Figures 1 to 6 As shown, in some embodiments of the present invention, the left side of the door body 2 is provided with a protrusion 22, and the door frame 1 is provided with a second groove 14 at the position corresponding to the protrusion 22. The top and bottom of the protrusion 22 are provided with mounting grooves 23. There are two automatic reset mechanisms 4, which are respectively located in two mounting slots 23.

[0047] Specifically, the protrusion 22 refers to a protruding structure integrally formed or fixedly connected to the left side of the door body 2, used to guide the rotation of the door body 2 and install the reset mechanism. The whole is a block structure adapted to the second groove 14. Its width and thickness need to meet the structural strength requirements during the rotation of the door body 2, while reserving enough space to open the installation groove 23. The second groove 14 refers to a groove structure opened on the inner side of the door frame 1 corresponding to the position of the protrusion 22. Its shape matches the outline of the protrusion 22, and its depth can accommodate the partial embedding of the protrusion 22, providing guidance and limiting function for the rotation of the door body 2. The installation groove 23 refers to the embedded installation cavity opened on the top and bottom of the protrusion 22. Its size is adapted to the shape of the automatic reset mechanism 4. The groove can reserve connection structures such as buckle positions and threaded holes for fixing the automatic reset mechanism 4.

[0048] In detail, in the above-mentioned automatic reset baby fence safety gate with opening and closing monitoring, by setting a protrusion 22 on the left side of the gate body 2 and a second groove 14 at the corresponding position of the door frame 1, and at the same time, with the symmetrical arrangement of the double automatic reset mechanism 4, a collaborative structure of gate rotation guidance and balanced reset is constructed, which effectively solves the technical problems of uneven reset force, gate rotation jamming, and closing position deviation caused by the single-end arrangement of the traditional reset mechanism.

[0049] like Figures 7 to 12 As shown, in some embodiments of the present invention, the automatic reset mechanism 4 includes a first mating part 41 and a reset component 40, which are respectively disposed on the door frame 1 and the door body 2. The first mating part 41 has a first inclined surface 411; The reset assembly 40 includes a mounting housing 401, a second mating part 402, an elastic reset part 403, and an elastic support part 404, all of which are disposed within the mounting housing 401. One end of the elastic reset member 403 is connected to the second mating member 402, and the other end of the elastic reset member 403 is connected to the elastic support member 404. The second mating part 402 has a cavity structure. The end of the second mating part 402 away from the elastic support 404 is provided with a groove 405. The groove 405 has a second slope surface 406 that matches the first slope surface 411. The automatic reset baby fence with opening and closing monitoring has an open state and a closed state. In the closed state, the first ramp surface 411 abuts against the second ramp surface 406. During the transition from the closed state to the open state, the door body 2 rotates and opens relative to the door frame 1. The first ramp surface 411 presses against the second ramp surface 406 to push the second mating part 402 to overcome the elastic force of the elastic reset part 403 and move away from the first mating part 41. During the transition from the open state to the closed state, the elastic force of the elastic reset member 403 drives the second mating member 402 to move toward the first mating member 41, causing the door body 2 to rotate and close relative to the door frame 1.

[0050] The innovation of this solution lies in the sliding engagement between the first ramp surface 411 and the second ramp surface 406 on the second mating component 402, combined with the energy storage and release of the elastic reset component 403, to achieve a fully automatic reset function after the protective door is opened. The core idea is to utilize the ramp structure to efficiently convert the rotational opening motion of the door 2 into the linear compression motion of the second mating component 402, thereby storing kinetic energy in the elastic reset component 403. When the opening action stops, the stored elastic potential energy is released, driving the mechanism to move in the opposite direction, thus converting the linear motion back into the rotational closing motion of the door 2. Compared to the complex mechanical locking or electromagnetic drive solutions in existing technologies, this solution uses only two mating components with ramps and one elastic element working together, resulting in an extremely simple structure and significantly reduced cost. Furthermore, the reset force can be easily adjusted by replacing the elastic reset component 403 with different stiffnesses or adjusting the ramp angle, effectively solving the problems of complex structure, high cost, and unadjustable reset force in traditional solutions.

[0051] The working principle of this scheme is as follows: This structure achieves automatic reset during the opening and closing process of the protective door by constructing a synergistic mechanism of "sliding ramp surface - energy storage / release of elastic element". The core idea is to use the ramp surfaces that cooperate on the first mating part 41 and the second mating part 402 to convert the rotation of the door body 2 into the linear motion of the reset mechanism and the storage and release of elastic potential energy. Specifically, in the stable closed state, the first ramp surface 411 of the first mating part 41 and the second ramp surface 406 of the second mating part 402 abut against each other, and the structure is at a closed stable point. When the protective door changes from the closed state to the open state, the user pushes the door body 2 to rotate relative to the door frame 1, and the second mating part 402 fixed on one side moves accordingly. During the movement, due to the squeezing action of the first ramp surface on the first mating part 41, the second mating part 402 overcomes the elastic force of the elastic reset element 403 on it and moves away from the first mating part 41. During this process, the elastic reset member 403 is compressed, and part of the rotational kinetic energy of the door body 2 is converted into the elastic potential energy of the elastic reset member 403 and stored.

[0052] At this time, during the transition from the open to the closed state, the compressed elastic reset member 403 begins to release its stored elastic potential energy, which is converted into a restoring force that drives the second mating member 402 to move linearly towards the first mating member 41. Under the action of the restoring force, the second mating member 402 moves towards the first mating member 41, and the first ramp surface 411 and the second ramp surface 406 approach each other. The door body 2 rotates smoothly relative to the door frame 1 until the first ramp surface 411 and the second ramp surface 406 fully re-engage, and the structure returns to the initial closed stable state, thus completing one complete automatic reset cycle.

[0053] Overall, this technical solution achieves automatic door closing without external force intervention through the cooperation of the ramp surface and the elastic reset component 403. The structure is simple and reliable, and the reset force can be adjusted by component selection, fundamentally eliminating the safety hazards caused by the failure to reset in time after the protective door is accidentally opened.

[0054] like Figures 7 to 12 As shown, in some embodiments of the present invention, since the left side of the door body 2 is provided with a protrusion 22, the door frame 1 is provided with a second groove 14 at the position corresponding to the protrusion 22, and the top and bottom of the protrusion 22 are provided with mounting grooves 23; there are two automatic reset mechanisms 4, and the two automatic reset mechanisms 4 are respectively provided in the two mounting grooves 23.

[0055] Therefore, the mounting housing 401 can be securely fixed to the mounting groove 23 of the protrusion 22 by means of bolt connection.

[0056] To facilitate initial positioning during installation, a T-shaped clip 408 is provided on the exterior of the mounting housing 401, while a T-shaped slot 27 matching the T-shaped clip 408 is machined on the end of the door body 2 near the protrusion 22. During installation, the mounting housing 401 is first initially secured to the door body 2 using the T-shaped slot 27, and then bolts are used for final tightening. This design makes the installation process more convenient and accurate.

[0057] like Figures 7 to 12 As shown, in some embodiments of the present invention, the top and bottom of the second groove 14 are provided with guide posts 141, and the mounting housing 401 is provided with mounting holes 407 that cooperate with the guide posts 141.

[0058] Specifically, the guide post 141 refers to the columnar positioning guide component that is vertically fixed to the inner wall of the top and bottom of the second groove 14. It can be made of wear-resistant and rigid materials such as stainless steel or high-hardness engineering plastics. It has a cylindrical or square column structure and the surface can be smooth polished or rust-proofed. Its outer diameter needs to form a precise clearance fit with the inner diameter of the mounting hole 407. The end of the guide post 141 can be chamfered or rounded to facilitate assembly and docking with the mounting hole 407. The mounting hole 407 refers to the through hole structure opened in the mounting shell 401 at the position corresponding to the guide post 141. The inner wall of the hole can be equipped with a wear-resistant bushing to reduce wear caused by long-term relative movement. The opening position of the mounting hole 407 must ensure that the guide post 141 can accurately penetrate the mounting hole 407 after the mounting shell 401 is embedded in the mounting groove 23.

[0059] In detail, in the aforementioned automatic reset baby fence safety gate with opening and closing monitoring, by setting guide posts 141 at the top and bottom of the second groove 14, and simultaneously opening matching mounting holes 407 on the mounting shell 401, a precise positioning and motion guidance coordination structure for the automatic reset mechanism 4 is constructed, effectively solving the technical problems of installation positioning deviation, motion trajectory offset, and insufficient reset fit accuracy of traditional reset mechanisms. During the assembly stage of the automatic reset mechanism 4, the guide posts 141 can accurately position the mounting shell 401 through the mounting holes 407, ensuring that the two symmetrically arranged reset components 40 are on the same axis, avoiding asynchronous reset force output of the upper and lower automatic reset mechanisms 4 due to installation deviation; during the opening and closing rotation of the gate body 2, the sliding fit between the guide posts 141 and the mounting holes 407 can limit the motion trajectory of the mounting shell 401. Meanwhile, the rigid support of the guide column 141 can disperse the impact force generated when the reset assembly 40 is working, and prevent the mounting housing 401 from shaking or deforming in the mounting groove 23, further enhancing the balance of the reset force of the dual automatic reset mechanism 4, and ensuring the accuracy and stability of the door 2 reset and close.

[0060] like Figures 7 to 12 As shown, in some embodiments of the present invention, the elastic reset member 403 is a rubber elastomer or a spring. The elastic reset member 403 is preferably a spring.

[0061] In practical applications, rubber elastomers refer to components that utilize the elastic deformation of polymer materials such as rubber and silicone to store and release energy. They can be made into specific shapes such as cylinders and cubes, with the aim of providing nonlinear or near-linear restoring force through volume compression or shear deformation. Springs, on the other hand, specifically refer to mechanical components that use metal wire wound into a spiral shape to store and release energy through axial compression or tensile deformation. Their purpose is to provide a highly reliable restoring driving force with a clear force-displacement relationship (usually linear).

[0062] Specifically, this solution constructs a predictable, adjustable, and durable elastic energy storage and release core by selecting either a rubber elastomer or a spring as the elastic reset component 5, with a preference for springs. Due to its material properties, the rubber elastomer provides a certain damping effect, making the reset process smoother and quieter. Meanwhile, springs, such as compression springs, offer precise and stable linear elastic force due to their mature manufacturing process and stable metal material properties. Their wide range of stiffness coefficients facilitates accurate selection and matching based on the required reset force and speed.

[0063] like Figure 6 and Figure 13As shown, in some embodiments of the present invention, a third groove 24 is provided on the rear side of the door body 2, a lock tongue shell 25 is provided in the third groove 24, an unlocking component 26 is provided in the lock tongue shell 25, and the unlocking component 26 is used to drive the lock tongue body 31 to move; a U-shaped sensor 33 is provided in the lock tongue shell 25.

[0064] The latch in the locking monitoring component 3 can adopt a standard door lock structure in the prior art. Its interior typically includes a latch body 31 and an unlocking component 26. Both the latch body 31 and the unlocking component 26 can be set inside the latch housing 25 and achieve linear reciprocating movement through guide rails or slides. For example, the unlocking component 26 can be a door handle or button, which converts the external operating force into a push-pull force to drive the latch body 31 to move through mechanical transmission mechanisms such as springs, linkages, gears or cams.

[0065] The following example will provide a more detailed explanation of the above technical solution: In a specific home use scenario, this automatic reset baby gate with opening and closing monitoring is used as a safety barrier for baby activities in the family living room. For example... Figures 1 to 13 As shown, to achieve a compact integration of the door rotation guide and reset mechanism, a protrusion 22 is provided on the left side of the door 2 near the door frame 1. Correspondingly, a second groove 14 is provided on the inner side of the door frame 1 at a corresponding position to accommodate the protrusion 22. In this example, there are two automatic reset mechanisms 4, which are symmetrically arranged vertically and installed in the mounting grooves 23 at the top and bottom of the protrusion 22, respectively. This provides a balanced and stable reset force for the door 2, preventing tilting and jamming during the door reset process.

[0066] Specifically, in the two automatic reset mechanisms 4, two first mating parts 41 are respectively fixedly installed on the top inner surface and bottom inner surface of the second groove 14 of the door frame, and their outer sides are machined with a first slope surface 411. The two reset components 40 are respectively embedded in the top mounting groove 23 and bottom mounting groove 23 of the door body protrusion 22. Each reset component 40 is fitted with a mounting shell 401, which is firmly fixed in the mounting groove 23 by means of snap-fit ​​and bolt connection.

[0067] To achieve precise positioning and motion guidance of the reset assembly 40, guide posts 141 are vertically fixed on the top and bottom inner surfaces of the second groove 14, while mounting holes 407 are provided on the mounting housing 401 at the positions corresponding to the guide posts 141. During installation, the mounting housing 401 is first inserted into the mounting groove 23, allowing the guide posts 141 to accurately pass through the mounting holes 407 for initial positioning. Then, it is pre-fixed by snap-fit ​​and finally locked by bolts. This dual positioning and fastening design ensures installation accuracy and improves assembly efficiency, meeting mass production requirements.

[0068] The internal assembly sequence of the reset assembly 40 is as follows: First, the elastic support 404 is assembled inside the mounting housing 401; then, the elastic reset component 403 (a cylindrical helical spring is used in this example) is assembled on the elastic support 404; finally, the second mating component 402 is connected to the end of the elastic reset component 403 away from the elastic support 404. A clearance is provided between the second mating component 402 and the elastic support 404, allowing the second mating component 402 to reciprocate linearly along the axial direction of the guide post 141 inside the mounting housing 401.

[0069] In this example, the second mating component 402 is specially designed as a cavity structure with an open top. An inclined groove 405 is formed at the end of the component furthest from the elastic support 404. The bottom surface of this groove 405 forms a second inclined surface 406 that matches the first inclined surface 411. Correspondingly, the first inclined surface 411 of the first mating component 41 can extend into the cavity of the second mating component 402. When the door 2 is in the closed state, the first inclined surface 411 and the second inclined surface 406 are in close contact, ensuring the stability of the door closure.

[0070] In addition, an arc-shaped through groove 409 is provided on the mounting housing 401 to allow the first mating part 41 to move as the door rotates. That is, the arc-shaped through groove 104 guides the rotation of the first mating part 41 while also providing space for the rotation of the first mating part 41.

[0071] Meanwhile, at least one limiting groove 410 is provided on the outside of the second mating part 402. The limiting groove 410 extends along the height direction of the second mating part 402. A limiting post is provided on the inner wall of the mounting housing 401 to cooperate with the limiting groove 410. Its shape and size are precisely matched with the limiting groove 410. The limiting groove 410 is used to accommodate the limiting post and slide within its limited range. By setting the limiting post inside the mounting housing 401 and opening the limiting groove 410 on the outside of the second mating part 402, a precise linear guidance and stroke limiting mechanism is constructed. The limiting post acts as a fixed track, and the limiting groove 410 acts as a movable slider. The two cooperate with each other, forcing the second mating part 402 to slide back and forth only along the length direction of the limiting groove 410, i.e., the preset straight path, inside the mounting housing 401. This effectively prevents it from deflecting, jamming, or derailing during movement.

[0072] Meanwhile, to achieve real-time monitoring of the lock status of the protective door, this example has a third groove 24 on the rear side of the door body 2. A lock tongue shell 25 is installed in the groove, and the lock tongue body 31 is assembled inside the lock tongue shell 25. The lock tongue body 31 is slidably disposed in the first sliding groove 21 on the door body 2. The unlocking component 26 is also built into the lock tongue shell 25 to drive the lock tongue body 31 to slide. The channel plate 32 is fixedly connected to the lock tongue body 31, and the U-shaped sensor 33 is embedded inside the lock tongue shell 25 near the channel plate 32. The channel plate 32 has a channel notch 34, which can move synchronously with the lock tongue body 31 to achieve optical path on / off control. In addition, the door body 2 also integrates a controller and an alarm 5. The controller is electrically connected to the U-shaped sensor 33 and the alarm 5 respectively, forming a complete monitoring and early warning closed loop.

[0073] With the above configuration, one side of the mounting housing 401 is fixed to the door body protrusion 22 via the mounting groove 23, and the other side is fitted onto the guide post 141 of the door frame via the mounting hole 407. This ensures smooth rotation of the door body 2 relative to the door frame 1 while restricting its movement trajectory. The locking monitoring component achieves accurate feedback of the locking status through the linkage between the sliding of the lock tongue and the on / off state of the optical path. Its core working principle consists of two parts: first, the door body is automatically reset by the inclined surface cooperation of the first mating part 41 and the second mating part 402, combined with the energy storage and release of the elastic reset part 403; second, the lock tongue body 31 drives the channel plate 32 to move, changing the optical path state of the U-shaped sensor 33, and then the controller links the alarm 5 to achieve a safety warning.

[0074] The specific work process is as follows: I. Automatic Reset Working Process like Figures 7 to 12 As shown, when the security door transitions from the closed state to the open state, the user pushes the door body 2 to rotate around the axis of the guide post 141. The second mating component 402 fixed to the door body moves synchronously, and its internal second ramp surface 406 is squeezed by the first ramp surface 411 on the first mating component 41 fixed to the door frame. This squeezing force forces the second mating component 402 to overcome the elastic force of the elastic reset component 403 and move away from the first mating component 41, thereby compressing the elastic reset component 403 and converting the kinetic energy of the door body rotation into elastic potential energy for storage.

[0075] When the external force is removed and the protective door needs to transition from the open to the closed state, the compressed elastic reset member 403 releases its stored elastic potential energy, generating a restoring force that drives the second mating member 402 to move towards the first mating member 41. The second mating member 402 moves linearly along the axial direction of the guide post 141, and its internal second ramp surface 406 gradually re-engages with and engages with the first ramp surface 411, thereby pushing the door body 2 to rotate smoothly in the closing direction until the first ramp surface 411 and the second ramp surface 406 fully abut again, and the door body 2 returns to a stable closed state, completing one automatic reset cycle.

[0076] II. Locking Monitoring and Early Warning Process

[0077] like Figures 1 to 6 As shown, when the door 2 rotates to the closed position via the automatic reset mechanism 4, the latch body 31 slides along the first slide groove 21 under the pushing force of the door 2 closing, and the latch body 31 is embedded in the first groove 11 of the door frame 1, completing the mechanical locking. During this process, the channel notch 34 on the channel plate 32, which moves synchronously with the latch body 31, moves exactly between the optical paths of the U-shaped sensor 33, and the optical path is connected. The U-shaped sensor 33 transmits the connection signal to the controller, and the controller determines that the protective door is locked in place and does not trigger the alarm 5 to work.

[0078] If the safety door is opened, or if an infant accidentally touches it causing the latch body 31 to slide out of the first groove 11, the solid part of the channel plate 32 will block the light path of the U-shaped sensor 33, breaking the light path. The U-shaped sensor 33 will then transmit a disconnect signal to the controller. Upon receiving the signal, the controller will immediately issue a warning command to the alarm 5 based on preset logic. The alarm 5 will then activate an audible and visual warning to promptly remind parents that the safety door is in an unsafe state, thus eliminating potential safety hazards.

[0079] This specific example demonstrates the high integration and reliability of this baby fence safety gate in a real-world home setting through the guiding engagement of the protrusion 22 and the second groove 14, the symmetrical design of the dual automatic reset mechanism, the precise positioning of the guide post 141 and the mounting hole 407, and the multi-layered protection logic of "mechanical locking + optical path monitoring + audible and visual early warning." The nested design of the cavity-type second mating component ensures the structural compactness of the gate when closed while protecting the core ramp mating surface; the non-contact U-shaped sensor monitoring avoids monitoring failure caused by contact wear; and the coordinated work of the automatic reset mechanism and the monitoring and early warning system completely solves the safety risks of traditional baby fence safety gates—such as forgetting to close the gate or the inability to detect the locked state—from both passive protection and active early warning dimensions, providing comprehensive safety protection for infants and toddlers at home.

[0080] While the present invention has been disclosed above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the scope of protection of the present invention.
