Description

Technical Field

[0001] This invention relates to the technical field of modular power supply interface devices with overload protection for home appliances, specifically a modular power supply interface device with overload protection for smart home appliances. Background Technology

[0002] With the continuous popularization and development of smart home technology, various smart home appliances have been widely used in daily life, providing great convenience for people's production and life. During operation, smart home appliances need to be continuously connected to an external power source through a power interface to obtain a stable power supply. Under actual usage conditions, appliances are prone to circuit overload due to various reasons such as changes in the device's own operating status, insufficient power supply circuit capacity, abnormal circuit contact conditions, complex and variable usage environments, and poor interface compatibility.

[0003] When a line is overloaded, excessive current will continue to flow through parts with poor contact or weak load-bearing capacity, thereby generating a large amount of heat. This will cause obvious overheating and excessive temperature rise in the power connection area, gradually leading to thermal overload problems.

[0004] Prolonged thermal overload can directly lead to softening, deformation, and melting of the power supply interface and surrounding structure. In severe cases, it can cause safety accidents such as interface burnout, short circuits, or even fires, posing a great threat to personal and property safety. It can also affect the normal service life and operational stability of home appliances. Currently, most existing technologies for overload protection during the use of home appliances have obvious defects. They cannot provide timely and effective protection against thermal overload during the operation of home appliances, and it is difficult to avoid safety hazards caused by overheating and overload at the root. The aforementioned problems not only hinder the safe and standardized development of the home appliance industry but also reduce the safety and stability of daily electricity use, adversely affecting people's quality of life and user experience. Therefore, the industry urgently needs a modular power supply interface device with overload protection for smart home appliances that is structurally sound, responsive, safe, and reliable, capable of providing real-time protection against overload and overheating during appliance operation. This device should also have a modular structure and be flexibly adaptable to different appliances to compensate for the shortcomings of existing technologies and improve the safety and versatility of power supply for smart home appliances. Summary of the Invention

[0005] In view of this, a modular power supply interface device with overload protection for smart home appliances is proposed to solve the problems existing in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a modular power supply interface device with overload protection for smart home appliances, comprising: a power supply and a power supply connector, wherein the power supply connector is inserted into the power supply, and further comprising: a first component; The first component includes a housing A, a housing B attached to one side of the housing A, and a sliding groove provided on the sidewalls of both the housing A and the housing B, with an outward expansion member slidably connected within the sliding groove; Both housing A and housing B have a sub-shell at their bottom. A spring A is fixedly connected to the inner cavity of the sub-shell. A locking seat is fixedly connected to the bottom end of the spring A. The top of the locking seat slides within the inner cavity of the sub-shell. The four sub-shells are fixed to housing A and housing B respectively by fasteners and are symmetrically distributed in pairs. Both shell A and shell B have abdominal cavities. A multi-stage telescopic sleeve is inserted and fixed through the abdominal cavity. The tail end of the multi-stage telescopic sleeve is located inside the abdominal cavity, and the tail end of the multi-stage telescopic sleeve has an opening.

[0007] Preferably, a second component is also included; The second component includes a vertical cavity, in which a spring B is fixedly connected, and a stop member is fixedly connected to the bottom end of the spring B. The top of the stop member slides within the vertical cavity. The bottom surface of the abutment is provided with a recessed groove, and a temperature sensor is installed in the recessed groove.

[0008] Preferably, both housing A and housing B are provided with threaded grooves, and a screw ring is threaded into the threaded groove. A connecting piece is symmetrically fixed to the bottom surface of the screw ring, and an electrically controlled telescopic rod is fixedly connected to each connecting piece. A displacement piece is fixedly connected to the bottom end of both electrically controlled telescopic rods.

[0009] Preferably, the housing A and housing B are connected by bolts to form a cover shell; at the same time, both housing A and housing B are provided with through holes for the power supply connection wires to pass through.

[0010] Preferably, the outer expansion member is provided with threaded holes and rope holes; and an auxiliary locking cover is composed of a sub-shell, spring A, and locking seat. The above allows the installation method of this design to be divided into three types: threaded, rope, and locking.

[0011] Preferably, the subshell, spring A, and locking seat constitute an auxiliary locking cover.

[0012] Preferably, the vertical cavity, spring B, abutment and temperature sensor constitute a temperature monitoring group. In this design, two groups are provided, which are fixed to the top wall of the inner cavity of shell A and shell B respectively, and are arranged symmetrically.

[0013] Compared with the prior art, the present invention provides a modular power supply interface device with overload protection for smart home appliances, which has the following advantages: 1. The present invention, through the design of a gas-driven multi-stage telescopic sleeve for adaptive fastening and clamping of the first component, offers the following advantages: Wide range of compatibility, enabling universal clamping of power supply connectors of various specifications: Adopting a gas-driven multi-stage telescopic sleeve structure, the telescopic length and clamping range can be adaptively adjusted according to the external size and structural specifications of the power supply connector. There is no need to customize a special interface for a single home appliance, breaking the limitation of poor compatibility of traditional interfaces, meeting the fastening and clamping needs of various smart home appliance power supply connectors, and greatly improving the versatility and reusability of the equipment. Highly efficient heat conduction and accurate capture of overload temperature rise signals: The multi-stage telescopic sleeve is set close to the power supply connector, and the two form a large-area contact. It can quickly and efficiently conduct the heat generated by the overload of the power supply connector to the connected abdominal cavity, avoid heat accumulation and delay the protection time, realize the real-time response to overload temperature changes, and provide a sensitive and reliable triggering basis for subsequent protection actions. Overload clamping self-locking reinforcement ensures maximum stability under hazardous conditions: Based on the physical principle that the air in the abdominal cavity expands due to overload heating, the thrust generated by the gas expansion acts in the opposite direction on the multi-stage telescopic sleeve, further tightening it against the power supply connector, forming a self-locking reinforcement effect of "the higher the temperature, the stronger the clamping", eliminating problems such as clamping loosening, connector displacement, and contact failure during overload protection, and ensuring the limited stability of the power supply connection part throughout the process; The purely physical linkage structure provides extremely high protection reliability: It integrates gas drive, adaptive clamping, heat conduction, and expansion locking functions into one unit. It does not require electronic components such as electrical control modules and sensor chips throughout the process, avoiding risks such as circuit failure, electromagnetic interference, and power failure. The pure mechanical and pneumatic coordination ensures stable operation and fast response speed. Even in complex and harsh operating environments, it can continuously provide stable clamping and overload protection, extending the overall service life of the equipment.

[0014] 2. The first component of this invention is designed with three fixing methods: threaded, rope-type, and snap-fit. This design offers the following advantages: The installation adaptability has been fully upgraded, and it is compatible with various scene layouts: This design relies on the threaded holes and rope holes opened in the slide, as well as the auxiliary locking cover composed of the sub-shell, spring A and locking seat, to integrate three installation methods: threaded, rope and locking. It can flexibly select the appropriate installation form according to different installation environments, installation positions and different carrier characteristics such as walls, cabinets and home appliances, completely breaking the scene limitations of a single installation method and meeting the installation needs of diversified power use scenarios such as home, kitchen and bathroom, and office. Fixed stability is controllable and adjustable, adapting to different working conditions: For different installation environments with stress and space characteristics, the installation mode can be selected accordingly: threaded type is suitable for long-term fixed and high load-bearing requirements, clip type is suitable for scenarios that need frequent disassembly and relocation, and rope type is suitable for flexible fixing scenarios in narrow spaces and irregular base surfaces. It takes into account both firmness and flexibility, ensuring that the power supply interface does not loosen or shift after installation, maintaining the stability of the power supply connection. The equipment is highly practical and versatile.

[0015] 3. The present invention, by constructing a temperature monitoring group using a vertical cavity, spring B, abutment component, and temperature sensor, offers the following advantages: Strengthening vertical constraint to prevent loose connections: This design combines a vertical cavity, spring B, abutment, and temperature sensor to form a temperature monitoring group, which works in conjunction with an auxiliary locking cover consisting of a sub-shell, spring A, and locking seat. Under the elastic buffer and drive of the two springs, a double vertical limiting structure is formed. This combination can provide a stable pressure on the power supply connector from the vertical direction, effectively offsetting the risk of loosening caused by vibrations during appliance operation and insertion / removal stress, ensuring that the power supply connector is always in a stable and constrained state on the power supply, and avoiding secondary overload and overheating problems caused by poor contact. The accuracy and stability of the sensing and monitoring are both improved: the temperature sensor relies on the contact part to achieve a tight fit with the power supply connector, which not only ensures the real-time and accuracy of temperature monitoring, but also overcomes the changes or displacement of the sensor head gap caused by vibration under the action of vertical constraint, and maintains the long-term stable fit between the sensor and the measured part; this structure eliminates the hidden dangers of sensor misjudgment and missed detection, and provides a highly reliable data foundation for overheating and overload judgment. Mechanical linkage adaptive compensation ensures dynamic and controllable fastening effect: The elastic design of springs B and A gives the entire limiting mechanism adaptive adjustment capability, automatically performing micro-expansion and contraction compensation based on the thermal expansion and contraction of the power supply connector and installation wear. This makes the vertical constraint of the connector not a rigid jam, but a dynamic and close-fitting fastening, avoiding damage to the connector caused by hard compression, and maintaining effective clamping of the connection part during long-term use, improving the durability and reliability of the equipment. Functional integration and optimized structural layout: The temperature monitoring group and the auxiliary locking cover are not independent functional units, but rather integrate the three major functions of temperature sensing, thermal overload response, and physical fixation through a clever combination of mechanical structures. This design eliminates the need for additional independent locking mechanisms, achieving a three-in-one integrated effect of "sensing-protection-fixation" without increasing the overall structural complexity, further aligning with the modular and compact design concept of the equipment.

[0016] 4. Through its overall design, this invention offers the following advantages: The present invention achieves the adaptation clamping function through the first component, which can stably and reliably clamp and fix power supply connectors of different specifications and structures, effectively improving the compatibility and universality of the interface and the power supply end of home appliances, meeting the power supply connection needs of diverse smart home appliances, and has a wider range of applications. The present invention automatically disconnects or cuts off the power supply when the power supply connection is overloaded by the second component. It can quickly cut off the power supply circuit in the early stage of dangerous conditions such as overload and overheating, and avoid damage to the connection parts caused by continuous high current and high temperature from the source. The protection response is timely and the safety protection effect is significant. The component adopts an adaptive clamping and overload power-off separation component structure design. The overall structure layout is reasonable and the operation is stable and reliable. It not only ensures the connection stability under normal power supply, but also realizes rapid protection under abnormal working conditions, which greatly reduces the safety hazards of interface melting, burning and even fire.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. Example

[0021] Please refer to Figures 1 to 7 As shown: To address the problems mentioned in the technical solutions, this application provides a modular power supply interface device with overload protection for smart home appliances, including: a power supply 1 and a power supply connector 2, wherein the power supply connector 2 is inserted into the power supply 1, and further includes: a first component 3; The first component 3 includes a housing A301, a housing B302 attached to one side of the housing A301, and a sliding groove 303 on the side wall of both housing A301 and housing B302. An outward expansion member 304 is slidably connected in the sliding groove 303. A secondary housing 305 is provided at the bottom of both housing A301 and housing B302. A spring A306 is fixedly connected to the inner cavity of the secondary housing 305. A locking seat 307 is fixedly connected to the bottom end of the spring A306. The top of the locking seat 307 slides in the inner cavity of the secondary housing 305. Four secondary housings 305 are fixed to housing A301 and housing B302 respectively by fasteners and are symmetrically distributed in pairs. A cavity 308 is provided in both housing A301 and housing B302. A multi-stage telescopic sleeve 309 is inserted and fixed through the cavity 308. The tail end of the multi-stage telescopic sleeve 309 is located in the cavity 308 and has an opening at the tail end.

[0022] in: Power supply 1 is a device that provides power to smart home appliances.

[0023] One end of the power supply connector 2 is inserted into the power supply 1, and the other end is connected to the smart home appliance.

[0024] The first component 3 is used to adapt to power supply connectors 2 of different sizes, models and installation positions; at the same time, it can stably clamp the power supply connector 2 to ensure that when there is an overload of smart home appliances, it assists the second component 4 in pulling the power supply connector 2 out of the power supply 1.

[0025] The housings A301 and B302 are connected by bolts to form a cover; at the same time, both housings A301 and B302 have through holes for the power supply connector 2 to pass through.

[0026] The expansion member 304 is slidably adapted to the slide groove 303; the expansion member 304 needs to be slid into the slide groove 303 in advance before the housing A301 and housing B302 are spliced.

[0027] The outer expansion member 304 has threaded holes and rope holes; and an auxiliary locking cover composed of a sub-shell 305, a spring A306, and a locking seat 307. The above allows for three installation methods in this design: threaded, rope, and locking. Multiple installation methods can effectively adapt to different installation environments / locations.

[0028] The auxiliary locking cover is composed of the sub-shell 305, spring A306, and locking seat 307. When installed by locking, the auxiliary locking cover can work with the cover to restrict the power supply 1 and the power supply connector 2 plugged into it.

[0029] The mounting base 307 is equipped with a one-way air injection valve and an air vent for air injection and air venting when fixing / unlocking the power supply connection 2.

[0030] The multi-stage telescopic sleeve 309 has a port at its tail.

[0031] When the first component 3 is fixedly clamped and limited to the power supply connector 2, the power supply 1 and the power supply connector 2 are limited by the clamping method. Then, air is injected into the one-way air injection valve by the air pump. As the air is injected, the abdominal cavity 308 will gradually fill with gas. The multi-stage telescopic sleeve 309 will gradually extend through the port at the end of the multi-stage telescopic sleeve 309 to approach and abut the side of the power supply connector 2, and finally achieve the limit, which facilitates the overload protection (pull-out) action of the second component 4.

[0032] When the multi-stage telescopic sleeve 309 is in the state of limiting the power supply connector 2, its position close to the power supply connector 2 can effectively transfer the heat generated by the overload of the power supply connector 2 to the abdominal cavity 308 connected to it; with the rise of the overload temperature of the power supply connector 2, the air in the cavity will be heated and expanded, which will indirectly make the multi-stage telescopic sleeve 309 more closely abut against the power supply connector 2, ensuring that the limitation remains stable under the overload state.

[0033] A further embodiment: Please refer to Figures 2 to 5 , Figure 8 , Figure 9 As shown: The second component 4 includes a vertical cavity 401, a spring B402 fixedly connected inside the vertical cavity 401, an abutment 403 fixedly connected to the bottom end of the spring B402, and the top of the abutment 403 sliding within the cavity of the vertical cavity 401; a recessed groove is formed on the bottom surface of the abutment 403, and a temperature sensor 404 is installed in the recessed groove; threaded grooves are formed on both housing A301 and housing B302, and a screw ring 405 is threadedly connected to the threaded groove; a connecting member 406 is symmetrically fixedly connected to the bottom surface of the screw ring 405; an electrically controlled telescopic rod 407 is fixedly connected to each connecting member 406; and a displacement piece 408 is fixedly connected to the bottom end of both electrically controlled telescopic rods 407.

[0034] in: The second component 4 is used to monitor the temperature of the power supply connector 2 and to disconnect it from the power supply 1 in case of overload.

[0035] The vertical cavity 401, spring B402, abutment 403, and temperature sensor 404 constitute a temperature monitoring group.

[0036] The aforementioned temperature monitoring group and the auxiliary locking cover, consisting of the sub-shell 305, spring A306, and locking seat 307, can cooperate with each other. With the assistance of the springs in both, the vertical restriction on the power supply connector 2 can be improved, preventing it from becoming loose on the power supply 1.

[0037] The temperature sensor 404 can be implemented as an NTC thermistor.

[0038] The housings A301 and B302 are provided with threaded grooves for screwing the screw ring 405.

[0039] The bottom surface of the rotating ring 405 has a T-shaped groove for the sliding of the connector 406; the connector 406 can slide in the T-shaped groove, thereby moving the electrically controlled telescopic rod 407 and the shifting piece 408 to the position of the bottom of the power supply connector 2; furthermore, when using the snap-fit ​​type, the power supply connector 2 is not plugged into the power supply 1 before the above actions are performed. After the above operations are completed, the electrically controlled telescopic rod 407 retracts with the shifting piece 408, so that the shifting piece 408 is tightly attached to the bottom of the power supply connector 2 before the plugging action can be performed.

[0040] When the temperature sensor 404, which is in close contact with the power supply connector 2, detects that the temperature change exceeds the expected stable value / the highest temperature when the power supply connector 2 is not overloaded, the control unit, which is electrically connected to the temperature sensor 404 and the electric telescopic rod 407, will control the electric telescopic rod 407 to retract. When retracting, the electric telescopic rod 407 will pull the power supply connector 2 out of the power supply 1 through the shift piece 408, thereby avoiding damage to smart home appliances or even fire caused by overload.

[0041] The shifting piece 408 associated with the power supply connector 2 can be specifically configured according to the model of the power supply connector 2 available on the market, or it can be attached to the side wall of the power supply connector 2 according to its shape. The second component 4 is used to monitor the temperature of the power supply connector 2 and to disconnect it from the power supply 1 in case of overload.

[0042] The vertical cavity 401, spring B402, abutment 403, and temperature sensor 404 constitute a temperature monitoring group.

[0043] The aforementioned temperature monitoring group and the auxiliary locking cover, consisting of the sub-shell 305, spring A306, and locking seat 307, can cooperate with each other. With the assistance of the springs in both, the vertical restriction on the power supply connector 2 can be improved, preventing it from becoming loose on the power supply 1.

[0044] The temperature sensor 404 can be implemented as an NTC thermistor.

[0045] The housings A301 and B302 are provided with threaded grooves for screwing the screw ring 405.

[0046] The bottom surface of the rotating ring 405 has a T-shaped groove for the sliding of the connector 406; the connector 406 can slide in the T-shaped groove, thereby moving the electrically controlled telescopic rod 407 and the shifting piece 408 to the position of the bottom of the power supply connector 2; furthermore, when using the snap-fit ​​type, the power supply connector 2 is not plugged into the power supply 1 before the above actions are performed. After the above operations are completed, the electrically controlled telescopic rod 407 retracts with the shifting piece 408, so that the shifting piece 408 is tightly attached to the bottom of the power supply connector 2 before the plugging action can be performed.

[0047] When the temperature sensor 404, which is in close contact with the power supply connector 2, detects that the temperature change exceeds the expected stable value / the highest temperature when the power supply connector 2 is not overloaded, the control unit, which is electrically connected to the temperature sensor 404 and the electric telescopic rod 407, will control the electric telescopic rod 407 to retract. When retracting, the electric telescopic rod 407 will pull the power supply connector 2 out of the power supply 1 through the shift piece 408, thereby avoiding damage to smart home appliances or even fire caused by overload.

[0048] The displacement piece 408 associated with the power supply connector 2 can be specifically configured according to the model of the power supply connector 2 on the market, or it can be attached to the side wall of the power supply connector 2 according to the shape of the power supply connector 2.

[0049] The working principle of all the content in the above embodiments is as follows: This device completes modular adaptation and fastening clamping through the first component 3, and completes temperature monitoring and overload power-off protection through the second component 4. The overall working process is divided into five stages: installation and fixing, adaptive clamping, temperature monitoring, overload protection, and reset and reuse. The logic is coherent and the actions are orderly.

[0050] I. Installation and Fixing Stage Assemble the housing: Connect housing A301 and housing B302 with bolts to form a complete enclosure, so that the power supply connector 2's wiring passes through the reserved holes on the housing.

[0051] Choose an installation method: Depending on the usage scenario, select one of the three methods to fix the equipment: threaded, rope, or clip-on. Threaded / rope type: Adjust the position of the outer expansion part 304 in the slide groove 303, and fix it to the carrier such as wall or cabinet through the threaded hole or rope hole; Clip-on type: The auxiliary clip-on cover, consisting of sub-shell 305, spring A306, and clip-on seat 307, is used to clip the cover onto the outside of the power supply 1.

[0052] Assemble the power-off mechanism: Screw the screw ring 405 into the threaded groove of the housing, adjust the position of the connector 406, and align the electric telescopic rod 407 and the shifting piece 408 with the bottom of the power supply connector 2 and make them fit tightly.

[0053] II. Adaptive Clamping Phase Inflatable clamping: Inflate the abdominal cavity 308 through the one-way air injection valve of the clamping seat 307. The gas pushes the sleeve to extend outward through the tail port of the multi-stage telescopic sleeve 309, adaptively fitting the side wall of the power supply connector 2 and completing the fastening clamping.

[0054] Physical self-locking preheating: The multi-stage telescopic sleeve 309 is in close contact with the power supply connector 2, which can quickly conduct its working heat and prepare for subsequent overload response.

[0055] Vertical limiting reinforcement: Spring B402 inside the vertical cavity 401 pushes the abutment 403 downward, so that the temperature sensor 404 is tightly attached to the top surface of the power supply connector 2. Together with the auxiliary locking cover, a double vertical limiting is formed to prevent loosening.

[0056] III. Normal Operation and Temperature Monitoring Phase Power supply operation: Power supply connector 2 is stably plugged into power supply 1 to continuously supply power to smart home appliances.

[0057] Real-time monitoring: Temperature sensor 404 continuously collects the surface temperature of power supply connector 2 and transmits the data to the control unit to determine whether it is within a safe range.

[0058] Dynamic compensation: Springs A306 and B402 automatically fine-tune according to the thermal expansion and contraction of the power supply connector 2 to maintain the stability of clamping and monitoring.

[0059] IV. Overload Protection Execution Phase Overload trigger: When the power supply connector 2 overheats and the temperature exceeds the set threshold, the temperature sensor 404 sends an alarm signal to the control unit.

[0060] Pneumatic self-locking reinforcement: Overload heat is transferred to the abdominal cavity 308 through the multi-stage telescopic sleeve 309. The internal air expands due to heat and pushes the sleeve to further press against the power supply connector 2, so as to achieve "the higher the temperature, the stronger the clamping".

[0061] Automatic power-off: The control unit drives the electric telescopic rod 407 to retract quickly, and the power supply connector 2 is pulled out from the power supply 1 through the shifting piece 408, cutting off the power supply circuit and avoiding overheating, short circuit or fire.

[0062] V. Troubleshooting and Reset Phase Pressure relief and unlocking: After eliminating the overload fault, the gas in the abdominal cavity 308 is released through the vent of the locking seat 307, and the multi-stage telescopic sleeve 309 retracts to release the clamp.

[0063] Mechanism reset: Reinsert the power supply connector 2 into the power supply 1, adjust the shifting piece 408 to fit tightly against the bottom of the connector, inflate the abdominal cavity again to complete the clamping, and the equipment returns to normal working condition.

[0064] Please refer to the above work process. Figures 1 to 9 .
