Description

Technical Field

[0001] This invention relates to the field of Bluetooth circuit breaker technology, and in particular to a Bluetooth circuit breaker with ultra-low standby power consumption. Background Technology

[0002] Currently, Bluetooth circuit breakers are technologically mature and highly reliable. However, they are primarily designed for household appliances. Smart IoT energy meters, on the other hand, are emerging products jointly developed by the State Grid Corporation of China and major meter manufacturers. Their main feature is that, while maintaining the same structural size, they make room for modular design instead of built-in relays (for prepaid functions). The built-in relays (for prepaid functions) are replaced by external Bluetooth circuit breakers (for prepaid functions). To ensure functionality, the Bluetooth circuit breaker is installed at the back end of the smart energy meter. The user then bears the power consumption of the Bluetooth circuit breaker itself. However, the standby power consumption of Bluetooth circuit breakers is generally too high, which can easily lead to conflicts between power companies and users, indirectly undermining the government's credibility. Summary of the Invention

[0003] In view of this, the present invention provides a Bluetooth circuit breaker with ultra-low standby power consumption. The Bluetooth circuit breaker is controlled by an AC-DC power chip, which operates at a reduced frequency in standby mode, optimizes the gate drive to reduce switching losses, and outputs a fast dynamic response to meet the starting current requirements of a 12V DC motor. Furthermore, the external absorption circuit reduces switching losses and power consumption, enabling the present invention to achieve ultra-low standby power consumption, reducing steady-state standby power consumption to less than 0.1mA and active power consumption to less than 30mW. Compared with traditional Bluetooth circuit breakers, power consumption is reduced by more than 95%, meeting user needs and avoiding conflicts between power companies and users caused by excessive standby power consumption of Bluetooth circuit breakers.

[0004] This invention provides a Bluetooth circuit breaker with ultra-low standby power consumption, specifically including: a Bluetooth circuit breaker, wherein the internal control of the Bluetooth circuit breaker is achieved using an AC-DC power chip; a marking and mating block is fixedly installed on the right end face of the operating handle of the Bluetooth circuit breaker, the marking and mating block having a rectangular block structure; a pressure cavity A is formed on the left side of the marking and mating block, and a pressure cavity B is formed on the right side of the marking and mating block; both pressure cavities A and B have circular cavity structures and their structural dimensions are consistent; a through-hole is formed on the rear end face of the marking and mating block relative to both pressure cavities A and B; and two through-holes are formed on the front end face of the Bluetooth circuit breaker housing adjacent to the right side of its operating handle.

[0009] Furthermore, the outer peripheral surface of the pressing member B is in contact with the front end face of the limiting post inserted into the pressing cavity B. When the protruding end of the pressing member B is facing the limiting post, the limiting post is completely retracted into the limiting storage groove.

[0010] Furthermore, a rotating communication hole is provided at the axial center of the right side of the pressure chamber A, which passes through the pressure chamber B; a pressure component A is provided inside the pressure chamber A, which is a cam, and a rotating shaft A is fixedly installed on the right end face of the pressure component A, which is rotatably connected inside the rotating communication hole; the outer peripheral surface of the protruding end of the pressure component A is tangent to the inner peripheral surface of the pressure chamber A.

[0011] Furthermore, the outer peripheral surface of the pressing member A is in contact with the front end face of the limiting post inserted into the pressing cavity A. When the protruding end of the pressing member A is facing the limiting post, the limiting post is completely retracted into the limiting storage groove.

[0012] Furthermore, a slot B is provided at the center of the right end face of the rotating shaft B. The slot B has a hexagonal groove structure.

A slot A is provided at the center of the right end face of the rotating shaft A. The slot A has a hexagonal groove structure.

[0013] Furthermore, one of the six side end faces of slot B, which faces the same direction as the protruding end of the pressing member B, adopts an inclined surface structure with the bottom sloping inward, and the sloping angle is ten degrees; one of the six side end faces of slot A, which faces the same direction as the protruding end of the pressing member A, adopts an inclined surface structure with the bottom sloping inward, and the sloping angle is ten degrees.

[0014] Beneficial effects

[0015] 1. The Bluetooth circuit breaker of this invention uses an AC-DC power chip for control. It operates at a reduced frequency in standby mode, optimizes the gate drive to reduce switching losses, and outputs a fast dynamic response to meet the starting current requirements of a 12V DC motor. Furthermore, the external absorption circuit reduces switching losses and power consumption, enabling the invention to achieve ultra-low standby power consumption. It can reduce steady-state standby power consumption to less than 0.1mA and active power consumption to less than 30mW. Compared with traditional Bluetooth circuit breakers, power consumption is reduced by more than 95%, meeting user needs and avoiding conflicts between power companies and users caused by excessive standby power consumption of Bluetooth circuit breakers.

[0016] 2. This invention also includes a 5G module electrically connected to the AC-DC power chip. The 5G module is wirelessly connected to a mobile device for data transmission. The mobile device is the mobile phone of the person in charge of the Bluetooth circuit breaker. Therefore, when the Bluetooth circuit breaker trips due to arrears, the AC-DC power chip will wirelessly transmit data to the mobile device via the 5G module through the sensing of the iron induction block and the proximity switch. This will report to the person in charge of the Bluetooth circuit breaker, thus enabling the Bluetooth circuit breaker to trip and preventing power outages due to a Bluetooth circuit breaker malfunction.

[0017] 3. After the Bluetooth circuit breaker of this invention trips, the marker mating block, which moves with the operating handle of the Bluetooth circuit breaker, will press against the front end of the limiting plug located outside the limiting storage slot. When the rear end face of the marker mating block is in contact with the front end face of the Bluetooth circuit breaker housing, under the reset action of the reset spring, the front ends of the two limiting plugs will be respectively limited and inserted into the two through limiting holes, thereby limiting and fixing the current marker mating block. Because the marker mating block is fixedly connected to the operating handle of the Bluetooth circuit breaker, the Bluetooth circuit breaker cannot be closed before the limiting plugs are released from fixing the marker mating block. Through this design, the user or other personnel can be prevented from performing the closing operation on their own when the circuit breaker is tripped due to unpaid fees.

[0018] 4. This invention achieves the position change of the two limiting pins by using pressing parts A and B of the cam. When it is necessary to release the limiting pins from the marking mating block, it is only necessary to rotate the protruding ends of pressing parts A and B to face the limiting pins to achieve the limiting pins from the marking mating block. However, since pressing parts A and B are located inside pressing chambers A and B respectively, the position of their protruding ends cannot be observed from the outside. This design can also effectively prevent users or other personnel from correctly rotating pressing parts A and B to release the limiting pins from the marking mating block.

[0019] 5. The present invention, through the design of the inclined surface structure inside slots B and A, corresponds to the orientation of the protruding ends of the pressing members A and B, respectively. This allows personnel familiar with the structure to use tools to pull along the inner side surfaces of slots B and A sequentially when the Bluetooth circuit breaker needs to be closed, thereby determining which side surface is the inclined surface and thus knowing the current position of the protruding ends of the pressing members A and B. They can then rotate these surfaces to face the limiting pins, thereby releasing the limiting pins from fixing the marking mating block. Furthermore, the inclined surfaces inside slots B and A are designed with a 10-degree inward tilt at the bottom. This design makes the inclined surfaces completely invisible when viewed from the outside. This design prevents users or other personnel unfamiliar with the structure from noticing the inclined surface structure, thus avoiding their ability to release the two limiting pins from fixing the marking mating block.

[0041] To make the objectives, solutions, and advantages of the technical solutions of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments of the present invention.

[0042] Example: Please refer to Figures 1 to 16 As shown:

[0043] This invention provides an ultra-low standby power Bluetooth circuit breaker, comprising a Bluetooth circuit breaker 1. The Bluetooth circuit breaker 1 is controlled internally using an AC-DC power chip 107. It operates at a reduced frequency in standby mode, optimizes gate drive to reduce switching losses, and provides a fast dynamic response to meet the starting current requirements of a typical 12V DC motor (1.0A~1.4A). Furthermore, an external absorption circuit reduces switching losses and lowers power consumption. A marking and mating block 2 is fixedly mounted on the right end of the operating handle of the Bluetooth circuit breaker 1. The marking and mating block 2 has a rectangular block structure. 2. An internal pressure chamber A202 is provided on the left side of the inner side of the marking mating block 2, and an internal pressure chamber B203 is provided on the right side of the inner side of the marking mating block 2. Both pressure chambers A202 and B203 are circular cavity structures with the same structural dimensions. A through-limiting insertion hole 207 is provided on the rear end face of the marking mating block 2 relative to the pressure chambers A202 and B203. Two limiting storage slots 101 are provided on the front end face of the Bluetooth circuit breaker 1 adjacent to the right side of its operating handle. The limiting storage slots 101 are circular slot structures. When the Bluetooth circuit breaker 1 is operated... With the operating handle in the off-state, the rear end face of the marking mating block 2 is in contact with the front end face of the Bluetooth circuit breaker 1 housing. At this time, the two through-limiting insertion holes 207 are coaxial with the two limiting storage slots 101, and the diameter of the limiting storage slots 101 is larger than the diameter of the through-limiting insertion holes 207. A limiting pin 102 is fixedly connected to each of the two limiting storage slots 101 by a return spring 103. The limiting pin 102 has a cylindrical structure, and its diameter is consistent with the diameter of the through-limiting insertion hole 207. When the return spring 103 is extended, the limiting... The front end of the plug 102 is located outside the limit storage slot 101. When the Bluetooth circuit breaker 1 operating handle is in the closed state, the front ends of the two limit plugs 102 are respectively limited and inserted into the two through limit plug holes 207 to limit and fix the current marking mating block 2. Because the marking mating block 2 is fixedly connected to the Bluetooth circuit breaker 1 operating handle, the Bluetooth circuit breaker 1 cannot be closed before the limit plugs 102 limit and fix the marking mating block 2. Through this design, it is possible to prevent users or other personnel from performing the closing operation on their own when the circuit breaker is closed due to non-payment.

[0044] The Bluetooth circuit breaker 1 also has a 5G module 108 internally connected to the AC-DC power chip 107. The 5G module 108 is wirelessly connected to the mobile device 109, which is the mobile phone of the person currently in charge of the Bluetooth circuit breaker 1. The front surface of the Bluetooth circuit breaker 1 housing is also provided with an embedded groove 105 on the right side of its operating handle. A proximity switch 106 is installed inside the embedded groove 105 and is electrically connected to the AC-DC power chip 107. An iron sensing block 206 is embedded in the rear surface of the marking and mating block 2. When the operating handle of the Bluetooth circuit breaker 1 is in the unclosed state, the embedded groove 105 and the iron sensing block 206 are in the same position, and the iron sensing block 206 is within the sensing range of the proximity switch 106.

[0045] Among them, a rounded arc surface structure 201 is provided at the intersection of the rear end face and the top face of the marking mating block 2. By setting the rounded arc surface structure 201, when the operating handle of the Bluetooth circuit breaker 1 rotates together with the marking mating block 2 during the closing operation, there will be no contact obstruction between the marking mating block 2 and the front face of the housing of the Bluetooth circuit breaker 1, ensuring that the closing operation of the Bluetooth circuit breaker 1 can be carried out normally.

[0046] Each of the two limiting storage slots 101 has eight auxiliary balls 104 rotatably embedded in the adjacent opening ends of its inner circumferential surface. Four auxiliary balls 104 form a group, with each group arranged in a circular array. The auxiliary balls 104 contact the outer circumferential surface of the limiting plug 102. When the Bluetooth circuit breaker 1 operating handle disengages from the closed state, the marking mating block 2, before contacting the front end of the Bluetooth circuit breaker 1 housing, presses against the front end of the limiting plug 102 located outside the limiting storage slot 101, causing the front end of the limiting plug 102 to be pressed into the limiting storage slot 101. Through the contact and engagement between the auxiliary balls 104 and the outer circumferential surface of the limiting plug 102, the limiting plug 102 can be smoothly and unobstructedly pressed into the limiting storage slot 101 when pressed, avoiding friction and jamming that could affect the return operation of the Bluetooth circuit breaker 1 operating handle after disengagement from the closed state.

[0047] The right side of the pressure chamber B203 has a through-marked rotating through hole 205 on the right end of the mating block 2. Inside the pressure chamber B203, there is a pressure member B4, which is a cam. A rotating shaft B401 is fixedly installed on the right end of the pressure member B4 and is rotatably connected to the rotating through hole 205. The outer circumferential surface of the protruding end of the pressure member B4 is tangent to the inner circumferential surface of the pressure chamber B203. The outer circumferential surface of the pressure member B4 is tangent to the front end of the limiting post 102 inserted into the pressure chamber B203. When the protruding end of the pressure member B4 is facing the limiting post 102, the limiting post 102 is completely retracted into the limiting storage groove 101.

[0048] The right side of the pressure chamber A202 has a rotatable connecting hole 204 that passes through the pressure chamber B203. Inside the pressure chamber A202, there is a pressure component A3, which is a cam. A rotating shaft A301 is fixedly installed on the right end of the pressure component A3 and is rotatably connected to the rotating connecting hole 204. The outer circumferential surface of the protruding end of the pressure component A3 is tangent to the inner circumferential surface of the pressure chamber A202. The outer circumferential surface of the pressure component A3 is tangent to the front end of the limiting post 102 inserted into the pressure chamber A202. When the protruding end of the pressure component A3 is facing the limiting post 102, the limiting post 102 is completely retracted into the limiting storage groove 101.

[0049] The right end face of the rotating shaft B401 has a slot B402 at its axial center. The slot B402 has a hexagonal groove structure. A through hole 403, which passes through the left end face of the pressing member B4, is located at the center of the left side of the inner end of the slot B402. The diameter of the through hole 403 is larger than the diameter of the rotating shaft A301. The rotating shaft A301 is inserted into the through hole 403, and the right end face of the rotating shaft A301 is aligned with the left side of the inner end of the slot B402. A vertical plane; a slot A302 is provided at the center of the right end face of the rotating shaft A301. The slot A302 has a hexagonal slot structure. One of the six side end faces of the slot B402, which faces the same direction as the protruding end of the pressing member B4, adopts an inclined surface structure with the bottom sloping inward and the inclination angle is ten degrees. One of the six side end faces of the slot A302, which faces the same direction as the protruding end of the pressing member A3, adopts an inclined surface structure with the bottom sloping inward and the inclination angle is ten degrees.

[0050] The specific usage and function of this embodiment are as follows:

[0051] The Bluetooth circuit breaker 1 of this invention uses an AC-DC power supply chip 107 for control. It operates at a reduced frequency in standby mode, optimizes the gate drive to reduce switching losses, and provides a fast dynamic response, meeting the starting current requirements of a typical 12V DC motor (1.0A~1.4A). Furthermore, the external absorption circuit reduces switching losses and lowers power consumption (see attached diagram). Figure 16 As shown above, based on the above, the present invention achieves ultra-low standby power consumption, which can reduce steady-state standby power consumption to less than 0.1mA and active power consumption to less than 30mW. Moreover, through calculation, in actual application, the user only consumes 1 kWh of electricity every 3.8 years, which is negligible and meets the user's needs. It avoids the occurrence of conflicts between the power supply company and the user due to excessive standby power consumption of Bluetooth circuit breaker 1, and can help the State Grid Corporation to widely popularize the application of grid-connected smart IoT energy meters.

[0052] When the Bluetooth circuit breaker 1 receives a Bluetooth signal due to insufficient funds, the AC-DC power chip 107 controls the Bluetooth circuit breaker 1 to perform a tripping operation. After the Bluetooth circuit breaker 1 performs the tripping operation, the rear end face of the marking mating block 2, which is fixedly connected to the operating handle of the Bluetooth circuit breaker 1, will abut against the front end face of the outer shell of the Bluetooth circuit breaker 1. At this time, the embedded groove 105 corresponds to the position of the iron sensing block 206, and the iron sensing block 206 is within the sensing range of the proximity switch 106. The invention also includes a 5G module 108 electrically connected to the AC-DC power chip 107. Module 108 is wirelessly connected to mobile device 109 for data transmission. Mobile device 109 is the mobile phone of the person in charge of Bluetooth circuit breaker 1. Therefore, when proximity switch 106 senses iron induction block 206, it will give feedback signal to AC-DC power chip 107. AC-DC power chip 107 then wirelessly transmits data to mobile device 109 through 5G module 108, thereby reporting to the person in charge of Bluetooth circuit breaker 1. Bluetooth circuit breaker 1 can then be tripped to avoid the situation where power cannot be cut off due to failure of Bluetooth circuit breaker 1 to trip.

[0053] Furthermore, after the Bluetooth circuit breaker 1 trips, the marker mating block 2, which moves along with the operating handle of the Bluetooth circuit breaker 1, will press against the front end of the limiting post 102 located outside the limiting storage groove 101. This invention, through the contact and engagement of the auxiliary ball bearing 104 with the outer peripheral surface of the limiting post 102, allows the limiting post 102 to be smoothly and unobstructedly pressed into the limiting storage groove 101 when pressed, avoiding friction and jamming that could affect the return operation of the Bluetooth circuit breaker 1's operating handle. When the rear end face of the marker mating block 2 is in contact with the front end face of the Bluetooth circuit breaker 1's housing, the two through-limiting points... The position socket 207 is coaxial with the two limit storage slots 101. At this time, under the reset action of the reset spring 103, the front ends of the two limit plugs 102 will be respectively limited and inserted into the two through limit sockets 207, thereby limiting and fixing the current marking mating block 2. Since the marking mating block 2 is fixedly connected to the operating handle of the Bluetooth circuit breaker 1, the closing operation of the Bluetooth circuit breaker 1 cannot be realized before the limiting fixation of the marking mating block 2 by the limit plugs 102 is released. Through this design, it can be avoided that users or other personnel will perform the closing operation on their own when the circuit breaker is tripped due to non-payment.

[0054] Furthermore, the present invention achieves the position change of the two limiting pins 102 by using the pressing parts A3 and B4 of the cam. When it is necessary to release the limiting pins 102 from the marking mating block 2, it is only necessary to rotate the protruding ends of the pressing parts A3 and B4 to face the limiting pins 102 to achieve the limiting pins 102 from the marking mating block 2. However, since the pressing parts A3 and B4 are located inside the pressing chambers A202 and B203 respectively, the position of their protruding ends cannot be observed from the outside. This design can also effectively prevent users or other personnel from correctly rotating the pressing parts A3 and B4 to release the limiting pins 102 from the marking mating block 2.

[0055] Furthermore, the right end face of the rotating shaft B401 of the present invention has a hexagonal slot B402 at its axial center. One of the six side faces of slot B402, which faces the protruding end of the pressing member B4, has an inwardly inclined surface structure with a tilt angle of ten degrees. Similarly, the right end face of the rotating shaft A301 has a hexagonal slot A302 at its axial center. One of the six side faces of slot A302, which faces the protruding end of the pressing member A3, also has an inwardly inclined surface structure with a tilt angle of ten degrees. Through the design of the inclined surface structures inside slots B402 and A302, the... When the person in charge of the structure needs to close the Bluetooth circuit breaker 1, they can use a tool (such as a wire) to pull along the inner side of slot B402 and slot A302 in sequence to determine which side face is the inclined face, thereby knowing the position of the protruding end of the current pressing part A3 and pressing part B4, and rotate it to face the position of the limiting plug 102. At this time, under the pressure of the protruding end of the pressing part A3 and pressing part B4, the return spring 103 is compressed, and the two limiting plugs 102 are completely pressed and retracted into the limiting storage groove 101, thereby releasing its limiting fixation on the marking mating block 2. Therefore, the person in charge can perform the closing operation at this time.

[0056] Furthermore, the internal inclined surfaces of slot B402 and slot A302 of the present invention are both designed with a 10-degree inward tilt at the bottom. This design makes it impossible to detect the inclined surface when viewing slot B402 and slot A302 from the outside. This design prevents users or other personnel who are unaware of the structure from noticing the inclined surface structure, thereby avoiding the release of the two limiting pins 102 from fixing the marking mating block 2.

[0057] The above description is merely an exemplary embodiment of the present invention and is not intended to limit the scope of protection of the present invention, which is determined by the appended claims.
