DETAILED DESCRIPTION

[0042] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0043] In one embodiment, Figure 1 As shown, a battery pack is provided, which includes an energy storage power supply 3, a power port 4, a control component 5 and a power indicator light 6, wherein:

[0044] The energy storage power supply 3 is connected to the control component 5; the control component 5 is connected to the power port 4; the power port 4 includes a metal plug port and at least two USB ports, the metal plug port is used to connect to the target power tool, and the USB port is used to connect to external devices;

[0045] The power indicator light 6 is connected to the control component 5; when the power port 4 is connected to the target power tool and / or external device, the control component 5 is used to control the power indicator light 6 to turn on or off.

[0046] The energy storage power supply 3 may be composed of one or more rechargeable battery cells. The power port 4 is used to connect external devices, which may include target power tools and other electrical devices, to achieve physical power transmission.

[0047] The power port 4 includes a metal plug port and a USB port, wherein the metal plug port can be used to connect to the target power tool or the power supply device, and the USB port can be used to connect to other external devices, which can be power-consuming devices or power supply devices.

[0048] When the power port 4 is connected to the target power tool and / or external device, the control component 5 is used to control the power indicator light 6 to be turned on or off. The power indicator light 6 can be turned on directly by the control component 5, or the control component 5 can indirectly turn on the power indicator light 6 through the path of the energy storage power supply 3 when controlling the energy storage power supply 3 to charge or discharge the power port 4.

[0049] A battery pack provided in this embodiment is connected to a control component via a power indicator light; when the power port is connected to a target power tool and / or external device, the control component is used to control the power indicator light to turn on or off, so that the battery pack can display the power status when connected to the device, thereby achieving the effect of improving the visualization of battery pack parameters.

[0050] In one embodiment, the power indicator light includes a first indicator light, and the control component is connected to the first indicator light.

[0051] The first indicator light includes an LED light, and the flashing frequency of the LED light is adjustable;

[0052] When the battery pack is charging, the first indicator light flashes at a first flashing frequency;

[0053] When the battery pack is discharged, the first indicator light flashes at the second flashing frequency.

[0054] The first indicator light is used to indicate the status of charging and discharging. The first indicator light may include two flashing frequencies. The flashing frequency may be the number of times the first indicator light switches between on-off states within a unit of time. For example, the flashing frequency may be 0, that is, during the charging or discharging period, the first indicator light does not switch between on-off states after being turned on during the period; the flashing frequency may also be 1 Hz, that is, during the charging or discharging period, the first indicator light switches between on-off states at a frequency of once per second after being turned on during the period, thereby flashing the first indicator light. The flashing frequency may also be other available flashing frequencies or flashing frequencies that can be recognized by the human eye, which are not limited in this embodiment.

[0055] The battery pack provided in this embodiment can improve the visualization of the battery pack usage status by distinguishing the charging and discharging states using a flashing frequency, thereby achieving the effect of improving user experience.

[0056] In one embodiment, the power indicator light includes a first indicator light, and the control component is connected to the first indicator light.

[0057] The first indicator light includes an LED light, and the color of the LED light is adjustable;

[0058] When the battery pack is charging, the first indicator light is lit in the first color;

[0059] When the battery pack is discharged, the first indicator light is lit in the second color.

[0060] The first indicator light may light up in two colors for indication.

[0061] The flashing frequency can be the number of times the first indicator light switches on and off within a unit time. The specific colors used for the first color and the second color can be set according to actual needs, such as the necessity of warning, cost, etc., and this embodiment does not limit this.

[0062] In another embodiment, the first indicator light may be a combination of LED lights of multiple colors, and when the battery pack is charging or discharging, a single LED light or a combination of LED lights may be turned on, thereby achieving multi-color indication.

[0063] In one embodiment, the power indicator light includes a second indicator light, and the control component is connected to the second indicator light.

[0064] The second indicator light includes an LED light group, and the second indicator light displays the power level of the battery pack.

[0065] The LED light group is composed of multiple LED lights, and each LED light can represent a part of the battery pack status.

[0066] In one embodiment, the LED light group includes four LED lights, each representing 25% of the power level. The control component collects the current state of charge of the energy storage power supply and determines the target number of LED lights to be turned on based on the state of charge. For example, when the power level corresponding to the state of charge is 25%, only one LED light may be turned on.

[0067] The battery pack provided in this embodiment can provide more detailed and intuitive battery status information by displaying the power level of the LED light group, thereby improving the visualization effect of the battery pack parameters.

[0068] In one embodiment, the second indicator light and the USB port are respectively disposed on two sides of the battery pack.

[0069] The second indicator light and the USB port are respectively arranged on both sides of the battery pack, and can be respectively arranged at the front and rear ends of the battery pack, so that the second indicator light is not blocked by the device during charging or discharging.

[0070] In one embodiment, the battery pack is provided with a soft rubber protective cover on one side of the USB port.

[0071] Among them, the soft rubber protective cover can be made of soft, elastic and plastic materials such as silicone and nitrile rubber, so as to prevent external obstacles such as dust and debris from entering the USB port and affecting the normal operation of the battery pack, thereby improving the durability and safety of the battery pack.

[0072] In one embodiment, the USB port includes at least one of a USB-A port, a USB-B port, and a USB-C port.

[0073] USB (Universal Serial Bus) is a serial bus standard and a technical specification for input and output interfaces, widely used in information and communication products such as personal computers and mobile devices. When the power port also includes USB-A, USB-B, and USB-C ports, the battery pack can power not only the target power tool but also a variety of mobile devices such as personal computers, thereby achieving a more extensive power supply.

[0074] The battery pack provided in this embodiment integrates at least one USB port into the battery pack used in the target power tool, so that the battery pack can power a wide range of devices, thereby improving the flexibility and applicability of the battery pack.

[0075] In one embodiment, the battery pack further includes a housing;

[0076] A cavity is formed inside the shell, and an energy storage power supply and a control component are arranged in the cavity; an opening is opened on the shell for the power port to extend out of the shell, so that the target power tool and / or external device can be connected to the power port.

[0077] The housing is the outer frame of the battery pack and can be made of durable materials such as plastic, metal, or composite materials. It protects sensitive components within from external factors such as impact, water, and dust. The cavity formed within the housing houses components such as the energy storage power supply and control components. The housing also features an opening for the power port to extend beyond the housing for connecting external devices and inputting user commands.

[0078] The battery pack provided in this embodiment ensures that the battery pack is strong and durable while facilitating user interaction with the battery pack.

[0079] In one embodiment, the housing includes an upper housing and a lower housing;

[0080] The upper shell and the lower shell are detachably connected; a first positioning portion is provided on the edge of the side wall of the upper shell, and a second positioning portion is provided on the edge of the side wall of the lower shell, and the positions of the first positioning portion and the second positioning portion match.

[0081] The detachable connection between the upper and lower shells makes assembly, maintenance, and upgrades of the battery pack more convenient. The first and second positioning features along the side walls allow for quick alignment of the upper and lower shells during assembly, ensuring a secure connection between the shells.

[0082] A battery pack provided in this embodiment can reduce production and maintenance costs and improve durability and reliability by providing the first positioning portion and the second positioning portion of the upper shell and the lower shell.

[0083] In one embodiment, the battery pack further includes a circuit board, the control component and the power port are disposed on the circuit board, and the energy storage power source is electrically connected to the circuit board; the power port includes a USB port;

[0084] The energy storage power supply is arranged on a side of the cavity close to the lower shell, the circuit board is arranged on a side of the cavity close to the upper shell, and the USB port is arranged on a side of the circuit board facing the energy storage power supply.

[0085] The energy storage power supply is located inside the cavity, near the lower housing. Furthermore, the lower housing may be provided with heat dissipation holes to help the energy storage power supply dissipate heat during operation. The circuit board is used to carry the control components and the power port. The USB port is located on the side of the circuit board facing the energy storage power supply, which can prevent the circuit board from causing the housing to become too large due to accessories. In one specific embodiment, the USB port includes a USB-A port and a USB-C port, and the USB-A port and the USB-C port can be located between the circuit board and the energy storage power supply.

[0086] In order to more clearly illustrate the technical solution of the present application, the present application also provides a detailed embodiment. In one embodiment, Figures 1 to 3 As shown, a battery pack 100 is provided, which includes a housing 1, a circuit board 2, an energy storage power supply 3, a power port 4, a control component 5, a power indicator light 6 and a user command acquisition component 7. The power port 4 includes a metal plug port 41 and a USB port 42, wherein:

[0087] The housing 1 includes an upper housing 11 and a lower housing 12; the upper housing 11 and the lower housing 12 are detachably connected; Figure 4 and Figure 5 As shown, a first positioning portion 111 is provided on the edge of the side wall of the upper shell 11, and a second positioning portion 121 is provided on the edge of the side wall of the lower shell 12. The first positioning portion 111 and the second positioning portion 121 are matching recesses, and the positions of the two match, so that the matching positions of the upper and lower shells can be positioned more quickly through the first positioning portion 111 and the second positioning portion 121, reducing the difficulty and labor cost in assembling the upper and lower shells.

[0088] Furthermore, the upper shell 11 and the lower shell 12 are detachably connected by at least two connecting studs 13. The upper and lower ends of the connecting studs 13 are limited, and the USB port 42 is positioned between two of the connecting studs 13. This can effectively prevent the USB port 42 from being squeezed and damaged when the battery pack 100 falls or is hit.

[0089] The upper housing 11 is also provided with a lock 15 and an elastic member 14 fixed relative to the lock 15. The housing 1 has an opening for the lock 15 to extend from the housing 1. The user can use the lock 15 to detachably secure the target power tool to the battery pack 100. The upper housing 11 is also provided with a ventilation hole 17.

[0090] The battery pack 100 is provided with a soft rubber protective cover 18 on one side of the USB port. The soft rubber protective cover 18 can be made of a soft, elastic and plastic material such as silicone rubber or nitrile rubber.

[0091] The housing 1 defines a cavity within which the energy storage power source 3 and control assembly 5 are disposed. The housing 1 includes a mating recess and an opening for the power port 4 to extend out of the housing 1, allowing the target power tool and / or external device to connect to the power port 4. Furthermore, the target power tool can be aligned using a retaining protrusion 16 provided on the upper housing 11. The user can use this retaining protrusion 16 to push the battery pack 100 into the target power tool for connection.

[0092] The control assembly 5 and the power port 4 are disposed on the circuit board 2, and the energy storage power supply 3 is electrically connected to the circuit board 2. The energy storage power supply 3 is disposed within the cavity on a side close to the lower housing 12, and the circuit board 2 is disposed within the cavity on a side close to the upper housing 11. The USB port 42 is disposed on the side of the circuit board 2 facing the energy storage power supply 3. The USB port 42 includes at least one of a USB-A port, a USB-B port, and a USB-C port.

[0093] For example, Figure 6 As shown, the metal plug port 41 is arranged on the side of the circuit board 2 facing the upper shell 11, and the pin height of the metal plug port 41 is H1. The USB port 42 is arranged on the side of the circuit board 2 facing the energy storage power supply 3, and the height from the metal plug port 41 to the USB port 42 is H2, wherein H2>H1, so that the USB port 42 and the metal plug port 41 are distributed on both sides of the circuit board 2, thereby facilitating the use of the space between the circuit board 2 and the battery pack 100, while retaining the surface shape of the upper shell 11, reducing the changes in the adaptation structure between the tools.

[0094] like Figure 7 As shown, in one embodiment, H2 is less than 20 mm, and 1.6>H2 / H1>1. In one embodiment, when the USB port 42 is a USB-A port, H2 can be 19.83 mm; when the USB port 42 is a USB-C port, H2 can be 17.31 mm, and the pin height H1 is 13 mm.

[0095] The battery pack 100 also includes a power supply bracket 19, and the energy storage power supply 3 is fixed in the cavity through the power supply bracket 19. The energy storage power supply 3 is connected to the control component 5; the energy storage power supply 3 is a rechargeable battery, including a preset number of single cells, which are connected in series and parallel. The size of the housing 1 matches the size of the preset number of single cells connected in series and parallel. In a specific embodiment, Figure 8 As shown, the length of the housing 1 matches the size of five single batteries, which is 119.47 mm.

[0096] like Figure 9 As shown, the control component 5 is connected to the energy storage power supply 3 and the power port 4; the control component 5 includes a Type-C main control MCU and a power protection MCU. The Type-C main control MCU is also connected to a user instruction acquisition component 7 and a USB port 42. The USB port 42 includes an A port and a C port, namely a USB-A port and a USB-C port. The user instruction acquisition component 7 is a button K3, which is used to collect the user's pressing operation. The energy storage power supply and the power indicator light 6 are powered, and the power indicator light 6 is also connected to a switch K1, which can be used to control the power indicator light 6 to be turned on or off; the energy storage power supply 3 includes a B+ port and a B- port. The B+ port is connected to the metal plug port 41 through the filter F1, the filter F2, the switch MOSFET-P QC2, and the switch MOSFET-P QC1 in sequence. The connection point between the filter F1 and the filter F2 is also connected to the P+ end. The power indicator light 6 is also connected to the control component 5, which is not shown in the figure;

[0097] Metal plug port 41 and USB port 42 are arranged in the same direction. This helps protect USB port 42 during use of the target power tool. Metal plug port 41 is used to connect to the target power tool, while USB port 42 is used to connect to external devices. Power port 4 is used to connect to power-consuming devices and / or power supply devices.

[0098] The control component 5 is used to obtain the access signal of the power port 4 and determine the access device corresponding to the access signal; if the access device is a power-consuming device, a control instruction is sent to the energy storage power supply 3 to cause the energy storage power supply 3 to discharge to the power port 4; multiple power ports 4 can discharge simultaneously, thereby providing power to multiple electrical appliances and tools at the same time, allowing multiple devices to be used at the same time.

[0099] When the power port 4 is connected to a power-consuming device and a power supply device at the same time, the power supply device charges the energy storage power supply 3, and the energy storage power supply 3 discharges the power-consuming device. At least two USB ports 42 can be used for charging and discharging respectively. Through the above settings, the emergency use of the battery pack 100 can be achieved without waiting for the energy storage power supply 3 to be fully charged before discharging to the power-consuming device. For example, when the charging power is greater than the discharging power, emergency use can be achieved for low-power electrical appliances. The control component 5 includes a PD protocol chip, which can identify the connected device through the CC communication of the C port, and determine it as a power-consuming device or a power supply device, and discharge as a power source and charge as a powered device respectively. In a specific embodiment, when the metal plug port 41 is used for charging, the battery pack 100 can be discharged through the USB-A port and the USB-C port in the USB port 42.

[0100] When the device connected to the power port 4 is a power supply device, the power supply device charges the energy storage power source 3; multiple power ports 4 can be charged simultaneously, thereby increasing the charging speed and reducing the charging time of the battery pack 100.

[0101] The power indicator light 6 is connected to the control component 5; when the power port 4 is connected to the target power tool and / or external device, the control component 5 is used to control the power indicator light 6 to turn on or off.

[0102] The power indicator light 6 includes a first indicator light, the control component 5 is connected to the first indicator light, and the first indicator light includes an LED light, the color and flashing frequency of the LED light are adjustable; when the battery pack 100 is charging, the first indicator light is lit in a first color and flashes at a first flashing frequency; when the battery pack 100 is discharging, the first indicator light is lit in a second color and flashes at a second flashing frequency.

[0103] In one embodiment, when the USB-C port is charging, the first indicator light flashes to indicate that the device is charging; when the USB-A port or the USB-C port is discharging, the first indicator light is constantly on to indicate that the device is discharging. In one embodiment, when the USB-C port is charging, the first indicator light flashes red to indicate that the device is charging; when the USB-A port or the USB-C port is discharging, the first indicator light is constantly on green to indicate that the device is discharging.

[0104] The power indicator light 6 includes a second indicator light, which is connected to the control assembly 5 and includes an LED light group. The second indicator light displays the battery pack 100's power level, providing a multi-stage power display for the battery pack 100. The second indicator light and the USB port 42 are respectively provided on opposite sides of the battery pack 100.

[0105] The second indicator light displays the power level of the battery pack 100, which can be controlled by the control component 5. The control component 5 is also used to: collect the charge status of the energy storage power supply 3 when the power port 4 is connected to an external device; determine the target number of LED light groups to be turned on based on the charge status; and control multiple LED light groups to be turned on based on the target number of LED light groups.

[0106] The control component 5 is also connected to the user instruction acquisition component 7, and is used to control the battery pack 100 to enter the working mode according to the wake-up instruction input by the user based on the user instruction acquisition component 7; the working mode includes: the control component 5 detects the connected device of the power port 4 in real time, and if the connected device is a power-consuming device, sends a control instruction to the energy storage power supply 3 to make the energy storage power supply 3 discharge to the power port 4.

[0107] The user instruction acquisition component 7 includes an operation button. When the battery pack 100 is in sleep mode: the operation button is used to detect the user's first press operation and generate a wake-up instruction. When the battery pack 100 is in working mode: the operation button is used to detect the user's second press operation and generate a sleep instruction. The control component 5 is also used to control the battery pack 100 to enter sleep mode according to the sleep instruction input by the user based on the user instruction acquisition component 7. When the battery pack 100 is in working mode, the control component 5 is also used to detect the connected device of the power port 4 in real time. If no connected device is detected within a preset time range, the battery pack 100 is controlled to enter sleep mode. The first press operation is a single press within a preset time length, and the second press operation is two presses within a preset time length.

[0108] Correspondingly, when the battery pack 100 enters the sleep mode, the first indicator light and the second indicator light are turned off, the USB-A port and the USB-C port are disconnected, and discharging stops.

[0109] like Figure 10 and Figure 11As shown, the battery pack 100 also includes a converter 8, which includes a converter port 81 and a converter port 82. The converter port 81 is a male terminal, and the metal connector port 41 is a female terminal. The converter 8 can be installed with a retaining groove that mates with the retaining protrusion of the battery pack 100. The converter 8 connects to the metal connector port 41 through the converter port 81. The converter port 82 includes a metal port and a USB port 42 arranged in the sliding direction. The USB port 42 includes at least one of a USB-A port, a USB-B port, and a USB-C port. The USB port 42 can be located on the end face or on the top surface of the battery pack 100. The metal port connects to the target power tool, and the profile of the converter port matches the profile of the target power tool's power port. By configuring the converter, a wider range of devices can be powered, eliminating the need for users to purchase or use additional battery packs 100 corresponding to different device connectors. The shell shape of the conversion part matches the shell shape of the coupling seat of the target power tool, so that the outline of the power supply port of the target power tool matches the outline of the conversion port of the conversion part. After the matching shell and battery pack 100 are matched, the USB port 42 is covered, thereby preventing dust and other debris from entering the USB port 42 during the use of the target power tool, thereby protecting the port from being blocked and damaged.

[0110] like Figure 12 As shown, the battery pack 100 can be pushed into the base of the target power tool 200 through the limiting protrusion on the battery pack 100, so that the battery pack 100 can supply power to the target power tool 200.
