The communication module can transmit relevant data of the BMS chip and microcontroller to the power management APP through WIFI, Bluetooth, etc., and then provide feedback or alarm through the power management APP. At the same time, the power management APP can also adjust the charging protection strategy of the BMS chip and microcontroller through other software.

[0081] The microcontroller is also used to receive the real-time charging information of the battery from the BMS chip, and send the real-time charging information of the battery to the power management APP through the wireless communication module for synchronous display.

[0082] The BMS chip used in this application is a mature chip, which is mainly used for battery monitoring and management, and has the following main functions: 1) Real-time monitoring of battery physical parameters: Real-time acquisition of key physical parameters such as battery voltage, current, temperature, etc. 2) Battery state estimation: Estimate the remaining capacity (SOC), health state (SOH), etc. of the battery through algorithms. 3) Online diagnosis and early warning: When the battery has abnormal conditions, such as overcharging, over-discharging, overcurrent, overheating, etc., the BMS chip can detect and issue early warnings in time. 4) Charge and discharge and pre-charge control and balance management: Ensure the safety and efficiency of the battery during the charging and discharging process. 5) Thermal management: By controlling the battery's heat dissipation and heating system, ensure that the battery operates within an appropriate temperature range.

First, the BMS chip monitors and provides early warnings for battery voltage, capacity, and charge and discharge. This allows for timely detection and resolution of battery anomalies, effectively avoiding safety issues caused by battery failures and ensuring battery charging safety and quality. Secondly, the BMS chip manages charge and discharge, as well as thermally, for overcharge, over-discharge, overcurrent, and overheating. This reduces damage to the battery during charging and extends battery life, effectively protecting electronic devices connected to power strips. Finally, when the battery is overcharged, over-discharged, overcurrent, or overheated, a power-off protection command is generated to stop powering the battery, further ensuring battery charging safety.

[0083] The microcontroller used in this application is mainly responsible for receiving the power-off protection instructions of the BMS chip in the solution, and controlling the power-off state of the charger socket according to the instructions. First, when the battery is overcharged, over-discharged, overcurrent or overheated, the microcontroller can control the charger socket to enter the power-off state and stop supplying power to the battery, thereby further ensuring the safety of battery charging. Secondly, the microcontroller adopts integrated circuit technology, which is suitable for application scenarios of battery power monitoring and protection charging, and effectively reduces the power consumption of the entire power strip structure.

Finally, the microcontroller has a high degree of integration, and the collaboration and stability between functional units are guaranteed, with high reliability.

[0084] This application transmits relevant data of the BMS chip and microcontroller to an external APP through a communication module. First, through the communication module, users can obtain data such as battery status and charging information in real time through the external APP, which is convenient for remote monitoring and management. Secondly, the communication module divides the data transmission function of the entire power strip structure into independent modules, which facilitates modular management and improves the maintainability and scalability of the entire power strip structure.

[0085] In summary, the present application is for a power strip structure for battery power monitoring and protection charging. By collecting real-time charging information of the battery to dynamically monitor the voltage, capacity and charge and discharge process, the battery is protected from overcharge, over-discharge, overcurrent or overheating, so that the battery is maintained at a healthy power level. On the one hand, it effectively improves the situation in which modern families or collectives (units, companies) have many lithium-ion battery products and have long neglected charging, resulting in a reduction in the lifespan or damage to the lithium battery due to power shortage, thereby affecting the damage to the entire electronic product or accidents such as fire caused by charging; on the other hand, by monitoring the battery voltage, capacity and charge and discharge current, the battery power and charge and discharge are intelligently managed, the lithium ion activity is maintained, the life of the electronic product and the safe use of the power strip charger are extended; at the same time, the product can warn and block whether the battery is damaged, avoiding accidents such as fire caused by battery failure. Therefore, the present application thus achieves effective battery protection for electronic devices connected to the power strip, ensures the charging safety and charging quality of the battery, and achieves the purpose of reducing the probability of fire and extending the life of electronic products.

[0086] During the specific implementation process, the BMS chip is also used to identify the type of battery connected to the socket, and determine the optimal power, voltage, current and temperature for battery charging based on the battery type, and combine the real-time charging information of the battery to generate power-off protection instructions for overcharging, over-discharging, overcurrent and / or overheating management.

[0087] In this embodiment, the real-time battery charging information includes the battery type (e.g., lithium-ion, lithium polymer), charge level, voltage, current, and temperature (which can be determined by the charging resistance). When the battery charge level is higher than the optimal charge level, the battery is judged to be overcharged; when the battery voltage is lower than the optimal voltage, the battery is judged to be over-discharged; when the battery current is higher than the optimal current, the battery is judged to be overcurrent; and when the battery temperature is higher than the optimal temperature, the battery is judged to be overheated.

[0088] In a specific implementation, the display screen is also included, wherein the data input terminal is in data communication connection with the display data output terminal of the microcontroller;

[0089] The microcontroller is also used to receive the real-time charging information of the battery from the BMS chip and send the real-time charging information of the battery to the display screen for real-time display.

[0090] This application displays the battery charging information in real time on the display screen, which helps users to understand the battery charging status in a timely and intuitive manner, and thus better manage the charging process of electronic devices, thereby better achieving effective battery protection for electronic devices connected to the power strip.

[0093] The present application intuitively prompts the user to deal with abnormal situations during battery charging by issuing a sound alarm, thereby facilitating better management of the charging process of the electronic device.

[0094] In the specific implementation process, it also includes a one-touch protection button that connects the control signal output terminal to the control information input terminal of the microcontroller for data communication;

[0095] When the one-button protection button is powered on, the microcontroller receives a corresponding charging protection instruction, which is used to control the socket to enter a power-off state when the battery power reaches a preset value to stop supplying power to the battery.

[0096] The user of this application can set the battery charging power through a one-touch protection button, that is, when the battery power is charged to a preset value, the socket is controlled to enter a power-off state, which is conducive to better management of the charging process of electronic devices.

[0097] In a specific implementation process, it also includes a one-touch full button that connects the control signal output terminal to the control information input terminal of the microcontroller for data communication;

[0098] When the full charge button is pressed, the microcontroller receives a corresponding full charge protection instruction, which is used to control the socket to enter a power-off state when the battery is fully charged to stop supplying power to the battery.

[0099] The user of this application can set the battery charging capacity to full charge through a one-touch full charge button, that is, when the battery is charged to full charge, the socket is controlled to enter a power-off state, which is also conducive to better management of the charging process of electronic devices.

[0100] Example 2:

[0101] This embodiment discloses a power strip structure.

[0102] The applicant discovered that traditional power strips only have two- and three-prong jacks, which are arranged crosswise on the power strip. As the world continues to evolve, the use of electronic devices such as smartphones and laptops has increased. Every time people charge their electronic devices, they need to use a power adapter, which is very inconvenient. People often lose the power adapter and cannot charge directly on the power strip.

[0103] To address the above-mentioned issues, Chinese patent publication number CN203242876U discloses a power strip with a USB port. The strip features a power socket and a USB port for directly charging electronic devices such as smartphones and laptops. The applicant discovered that most existing power strips with USB ports electrically connect the USB power supply to the strip's power cord, directly powering the USB port through the strip's power cord. However, electronic devices such as smartphones and laptops require power adapters to protect their batteries and extend their lifespan. Because the batteries of electronic devices like smartphones and laptops require stable direct current (DC) to charge, while the current supplied by the power cord of a power strip is generally AC, directly powering the USB port through the power cord can easily damage the battery and even create safety hazards. Therefore, designing a power strip structure for battery charge monitoring and protective charging that ensures safety when charging the batteries of electronic devices directly through the charging port, while also requiring minimal structural modification to the strip, is a technical problem that urgently needs to be addressed.

[0104] In view of the deficiencies of the above-mentioned prior art, the technical problem to be solved by this embodiment is: how to provide a power strip structure for battery power monitoring and protection charging, which can provide pure and stable AC power for the batteries of electronic devices, improve the problem that the batteries of electronic devices are easily damaged or have safety hazards, thereby improving the safety of the power strip when directly charging the batteries of electronic devices.

[0105] like Figure 2 As shown, a power strip structure includes a plug 1, a power cord 2, a housing 3, and a charger socket disposed inside the housing 3; the power input end of the power cord 2 is electrically connected to the plug 1; the power supply end of the charger socket is electrically connected to the power output end of the power cord 2; and a battery charging component is also disposed inside the housing 3;

[0106] Combine Figure 3 As shown, the battery charging assembly includes:

[0107] A rectifier, wherein the power input end of the rectifier is electrically connected to the power output end of the power line 2;

[0108] In this embodiment, the rectifier may be an existing three-phase bridge rectifier.

[0109] a filter, wherein the power input terminal of the filter is electrically connected to the power output terminal of the rectifier;

[0110] In this embodiment, the filter may be an existing single-phase fully controlled rectifier.

[0111] A voltage stabilizer, wherein the current power terminal of the voltage stabilizer is electrically connected to the power output terminal of the filter;

[0112] In this embodiment, the voltage regulator may be an existing linear voltage regulator, a switching voltage regulator, or the like.

[0113] a charging cable, wherein a power input end of the charging cable is electrically connected to a power input end of the voltage regulator;

[0114] A charging interface, wherein the power supply end of the charging interface is electrically connected to the power output end of the charging cable;

[0115] The housing 3 is provided with a charging window 33 having a size corresponding to that of the charging interface. The charging interface is correspondingly provided on the charging window 33 with its charging insertion end facing the outside of the housing 3 .

[0116] The working logic of the power strip structure in this application includes: inserting the plug into a fixed socket at home or company, and connecting the current through the power cord; the current in the power cord passes through the rectifier to convert AC power (home electricity and company electricity are generally AC power) into DC power, which is used to charge electronic devices such as smartphones or laptops that require DC power; the DC power converted by the rectifier is filtered out by a filter to remove noise and interference signals, because these noise and interference signals can easily damage the battery and charging circuit of the electronic device; the current processed by the filter passes through a voltage regulator to ensure the stability of the output current voltage, because the battery of the electronic device requires a constant voltage when charging, and too high or too low voltage will cause damage to the battery; the current processed by the voltage regulator is transmitted to the charging port through the charging cable, and the electronic device is directly charged through the charging port. The present application uses the rectifier, filter and voltage stabilizer of the battery charging component to rectify, filter and stabilize the current connected to the power cord of the power strip, so that the current finally transmitted to the charging cable and the charging interface is pure and stable AC power. This can better protect the batteries of the electronic devices and extend their battery life, thereby improving the problem that the batteries of the electronic devices are easily damaged or have safety hazards, thereby improving the safety of the power strip when directly charging the batteries of the electronic devices; at the same time, the original socket of the power strip is still powered by the power cord, that is, the improvement of the power strip by the present application does not affect the original function of the socket, and thus can make smaller modifications to the power strip while ensuring the safety of use of the power strip, making the structure of the power strip simpler.

[0117] In actual application, the related functions of battery management can be further developed based on the power strip provided by this application. For example, when an electronic device is charged through a charging interface, the battery data of the electronic device is read, and the charging process of the electronic device is further monitored and managed based on the read battery data, such as monitoring the voltage, capacity and charging and discharging current to ensure that the battery operates within a safe voltage, current and temperature (judged by the charging resistance); or providing overcharge, over-discharge, overcurrent, overheating and other protection functions to prevent battery damage; or controlling the charging and discharging process to ensure that the battery is charged and discharged in the best way and optimize battery performance and life; or supporting fault diagnosis and charge and discharge blocking, and charging blocking is mandatory when a fault occurs to ensure the safety of the battery and the charging place. At this time, the power strip structure used for battery power monitoring and protection charging may also include the following components:

[0118] A signal line, wherein a signal input end of the signal line is connected to a communication port of the charging interface for data transmission;

[0119] BMS chip, the data acquisition interface of the BMS chip is connected to the signal output end of the signal line for data transmission;

[0120] The microcontroller has a data input terminal connected to the data transmission interface of the BMS chip; and a control signal output terminal of the microcontroller is connected to the control terminal of the rectifier, filter and voltage regulator for data transmission.

[0121] At the same time, corresponding software needs to be set up on smartphones or other devices to realize data transmission and permission management.

[0122] In the specific implementation process, combined with Figure 2 and Figure 4 As shown, the shell 3 is a rectangular parallelepiped structure as a whole;

[0123] The front of the housing 3 is provided with a socket 31 corresponding to the outer dimensions of the socket and extending into the interior of the housing 3; the socket is correspondingly provided on the socket 31 with its plug-in end facing the outside of the housing 3;

[0124] It should be noted that the front side mentioned in this application refers to the side of the power strip facing the user when in use, the back side refers to the side opposite to the front side, and the side sides refer to the four sides between the front and the back side, that is, the shell 3 of the rectangular structure has a front side, a back side and four side sides.

[0125] One or more charging windows 33 are provided on the side of the housing 3 ; one or more charging ports corresponding to the charging windows 33 are provided inside the housing 3 .

[0126] like Figure 2 As shown, the power cord 2 is located on one side of the housing 3 after passing through the interior;

[0127] One or more charging windows 33 are provided on the side surfaces of the housing 3 except the side surface where the power cord 2 is located; one or more charging interfaces corresponding to each charging window 33 are provided inside the housing 3 .

[0128] By providing one or more charging ports on multiple sides of the housing 3, the present application can flexibly meet the needs of charging one or more electronic devices simultaneously, making the application range of the power strip wider and more flexible. For example, a power strip with one to three charging ports can be selected for home use, while a power strip with more charging ports can be selected for use in places with high demand, such as companies. In addition, the decentralized arrangement of the charging ports makes it less likely that the charging ports will interfere with each other, thereby improving the practicality of the power strip structure.

[0129] During the specific implementation process, the charging interface includes a Type-C interface, a Lightning interface and / or a USB interface.

[0130] This application can meet the charging needs of most devices through charging interfaces in the form of Type-C interface, Lightning interface and USB interface, thereby improving the practicality of the power strip structure.

[0131] During the specific implementation process, a first button switch is further provided inside the housing 3; the moving contact and the static contact of the first button switch are provided on the power cord 2 between its power input end and power output end, so that the power cord 2 can be turned on and off by opening and closing the first button switch;

[0132] like Figure 4 As shown, a power control hole 34 corresponding to the outer dimensions of the first button switch and extending through the interior of the shell 3 is provided on the front side of the shell 3 next to the socket 31; the first button switch is correspondingly provided on the power control hole 34 and the button cap faces the outside of the shell 3.

[0133] The present invention uses the first button switch to achieve overall power on / off management of the power strip, that is, it can generally power on and off the charging port and the existing socket, thereby improving the convenience of using and controlling the power strip structure. At the same time, the first button switch and its power control hole 34 are positioned so that they are easy to press and use and the overall structure is simple.

[0134] In a specific implementation, a second button switch is further provided inside the housing 3; the moving contact and the static contact of the second button switch are provided on the charging line between its power input terminal and power output terminal, so that the charging line can be turned on and off by opening and closing the second button switch;

[0135] like Figure 4As shown, a charging control hole 35 corresponding to the outer dimensions of the second button switch and extending into the interior of the shell 3 is provided on the front side of the shell 3 next to the socket 31; the second button switch is correspondingly provided on the charging control hole 35 and the button cap faces the outside of the shell 3.

[0136] In this embodiment, the power control hole 34 and the charging control hole 35 are adjacently arranged and their positions do not interfere with each other.

[0137] The present invention utilizes a second push-button switch to manage the power on and off of the charging port, enabling independent power on and off of the charging port while the original socket is functioning normally. This further enhances the flexibility and control convenience of the power strip. Furthermore, the second push-button switch and its power control hole 34 are positioned for ease of use and a simple overall structure.

[0138] In the specific implementation process, Figure 5 and Figure 6 As shown, the back of the housing 3 is provided with a recessed portion 36 that is recessed toward the front of the housing 3;

[0139] A rotating shaft 4 extending away from the back of the shell 3 is provided on the back of the shell 3 in the middle of the recessed portion 36; a limiting baffle 5 is provided on the end of the rotating shaft 4 away from the back of the shell 3, so that when the power cord 2 is wound on the rotating shaft 4, the limiting baffle 5 can limit the power cord 2.

[0140] In this embodiment, a wire hole is provided on the back of the housing 3 beside the rotating shaft 4 , and the power cord 2 passes through the wire hole from the inside of the housing 3 and can be wound around the rotating shaft 4 .

[0141] Combine Figure 7 As shown, the projection area of ​​the limiting baffle 5 along the central axis of the rotating shaft 4 is larger than the cross-sectional area of ​​the rotating shaft 4, so that when the power cord 2 is wound on the rotating shaft 4, the limiting baffle 5 can limit the power cord 2 to a position within the recess 36 between the limiting baffle 5 and the back of the housing 3 (as shown in FIG. Figure 6 and Figure 7 shown).

[0142] During actual use, the power cord 2 improves the scope of use and convenience of the power strip, but an overly long power cord 2 can also cause problems with storage. Therefore, the present application provides a recessed portion 36 and a rotating shaft 4 on the back side (i.e., the bottom) of the housing 3 of the power strip, so that the power cord 2 can be wound around the rotating shaft 4 at the bottom for storage, thereby further improving the flexibility of use and the convenience of control of the power strip structure. At the same time, the limiting baffle 5 can limit the power cord 2 to a position within the recessed portion 36 between the limiting baffle 5 and the back side of the housing 3, that is, it can ensure the storage stability of the wound power cord 2 and improve the problem that the wound power cord 2 is easily loose or falls. In addition, the present application's method of winding the power cord 2 at the bottom of the housing 3, in addition to having a better storage effect, can also further improve the problem that the power cord 2 is easily damaged (for example, if the power cord 2 is stored on the side of the power strip, it is more likely to be damaged), thereby further improving the safety of the power strip structure.

[0143] In the specific implementation process, Figure 8 As shown, a protective sheet 6 is provided on the side of the housing 3 at a position corresponding to the charging window 33;

[0144] The protective sheet 6 slides with the side of the housing 3 and the sliding direction is perpendicular to the axis of the charging window 33; when the protective sheet 6 slides toward the charging window 33 to the first preset position, it can completely cover the charging window 33 (such as Figure 8 When the protective sheet 6 slides to a second preset position away from the charging window 33, the charging window 33 can be completely exposed (as shown); Figure 9 The first preset position and the second preset position can be freely selected as needed, as long as they can completely cover / completely expose the charging window 33.

[0145] In this embodiment, a handle 61 is further provided on the side of the protection sheet 6 facing away from the side of the housing 3 , and the protection sheet 6 can be conveniently slid by the handle 61 in actual use.

[0146] like Figure 10 As shown, the present application has a sliding groove 37 integrally formed on the side of the housing 3, and the protective sheet 6 is stuck in the sliding groove 37 to slide along the side of the housing 3. In order to better arrange the sliding groove 37 and the protective sheet 6 and avoid interference with the charging window 33, the setting plane of the charging window 33 in the present application is recessed toward the interior of the housing 3 (forming a concave platform relative to the side of the housing 3), and the corresponding charging window 33 is set on this concave platform. This can better protect the charging port.

[0147] The present application protects the charging interface by providing a protective sheet 6 next to the charging interface. That is, when the charging interface is not in use, the protective sheet 6 can be slid toward the charging window 33 until it completely covers the charging window 33, thereby minimizing damage to the charging interface and further improving the safety of the power strip structure. At the same time, when the charging interface needs to be used, the protective sheet 6 can be slid away from the charging window 33 until it is completely exposed, without affecting the normal use of the charging interface. This structure is convenient to use and has a simple overall structure.

[0148] In the specific implementation process, combined with Figure 4 As shown, a display screen is also provided inside the housing 3; the power supply end of the display screen is electrically connected to the power output end of the voltage stabilizer;

[0149] When it is necessary to implement the relevant functions of battery management, the data input terminal of the display screen can also be connected to the display data output terminal of the microcontroller for data communication, so as to display some battery-related data and information through the display screen.

[0150] A display window 32 corresponding to the outer dimensions of the display screen and extending through the interior of the housing 3 is provided on the housing 3 beside the insertion hole 31 ; the display screen is correspondingly provided on the display window 32 with the display surface facing the outside of the housing 3 .

[0151] In this embodiment, the display window 32 is adjacent to the power control hole 34 and the charging control hole 35 and their positions do not interfere with each other.

[0152] The present application also includes a display screen (the functions and effects of which can be configured as needed, such as displaying battery data of charging electronic devices. The present application merely provides a display screen to facilitate subsequent functional expansion of the power strip). Furthermore, the current received by the display screen is pure, stable AC power processed by a rectifier, filter, and voltage stabilizer. This better protects the display screen and prevents potential safety hazards, thereby further improving the safety of the power strip structure. Furthermore, the position of the display screen and its display window 32 facilitates use and simplifies the overall structure.

[0153] It should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit the technical solution. Ordinary technicians in this field should understand that those modifications or equivalent replacements of the technical solution of the present invention that do not depart from the purpose and scope of the technical solution of the present invention should be included in the scope of the claims of the present invention.
