Description
Technical Field
[0001] This invention relates to the fields of power banks, flashlights, and desk lamps; more specifically, it relates to a modular device that has the functions of a power bank, a flashlight, and a desk lamp. Background Technology
[0002] Most portable power banks currently have a fixed capacity. In different usage scenarios, the capacity of the power bank may be too large or too small. If the capacity of the power bank is too large, it means that the user has to carry extra volume and weight. If the capacity of the power bank is too small, it means that the mobile device will run out of power, which will cause inconvenience to the user.
[0003] Currently, there is a type of portable power bank with variable capacity consisting of a main module and several sub-modules. Each of the main module and sub-modules contains a battery, and the capacity is variable by adding or removing sub-modules from the main module. However, since the sub-modules must be connected to the main module to be used, when the main module runs out of power, the user has to carry the depleted battery in the main module, which reduces portability. At the same time, this type of portable power bank does not have flashlight or desk lamp functions, and users need to purchase flashlights and desk lamps separately, which increases costs.
[0004] Currently, there is a type of power bank consisting of a charging head module and a battery module. The battery module is connected to the charging head module to form the power bank. The battery module is detachable. In different usage scenarios, users solve the problems of insufficient or excessive power bank capacity by carrying an appropriate number of battery modules. However, since the charging head module can only connect to one battery module at a time, the battery capacity of a single battery module is insufficient to charge high-capacity mobile devices, leading to the inconvenience of replacing the battery module midway. At the same time, since the charging head module can only charge one battery module at a time, when multiple battery modules need to be charged, the inconvenience of replacing the battery module midway will occur. The current solution is to set up a charging dock for multiple battery modules, but this increases costs. In addition, this type of power bank does not have flashlight or desk lamp functions, and users need to purchase flashlights and desk lamps separately, which increases costs.
[0005] Currently, there is a combination of a flashlight and a power bank. However, since the parts in this combination that are only used for the flashlight function cannot be disassembled, users have to carry the parts that are only used for the flashlight function when they only use the power bank, which reduces portability.
[0006] Currently, there is a type of USB flashlight head that connects to the USB output port of a power bank to form a flashlight. The USB flashlight head is detachable, so users don't need to carry the flashlight head when they only need the power bank. However, most USB flashlight heads lack dimming functionality, which is inconvenient for users. The current solution is to add buttons and dimming circuitry to the USB flashlight head, which increases costs. Since the USB flashlight head occupies a USB output port, a power bank with a single USB output port cannot simultaneously charge mobile devices when connected to the flashlight head, which is inconvenient for users. Because the USB flashlight head and power bank are designed separately and randomly combined, the shape and weight of the power bank and USB flashlight head are uncertain, which may result in a flashlight that is not suitable for the user's hand and may not be aesthetically pleasing. The USB flashlight head is only fixed to the power bank through the USB output port, and it is easy for the flashlight head to fall off the power bank when the user is running with the flashlight in hand, causing inconvenience.
[0007] Currently, there is a combination of a desk lamp and a power bank. However, since the parts in this combination that only function as desk lamps cannot be disassembled, users have to carry the parts that only function as desk lamps when using the power bank, which reduces portability.
[0008] Currently, there is a type of USB desk lamp head that connects to the USB output port of a power bank to form a desk lamp. The power bank acts as the base, and the USB lamp head is detachable, so users only need the power bank and don't need to carry the lamp head. However, most USB desk lamp heads lack dimming functionality. The current solution is to add buttons and dimming circuitry to the lamp head, which increases costs, the button placement is inconvenient for users, and the overall appearance is unsightly. Since the USB lamp head occupies a USB output port, a power bank with a single USB output port cannot simultaneously charge mobile devices when connected to the lamp head, causing inconvenience to users. Because the lamp head and power bank are designed separately and randomly combined, the shape and weight of the power bank are uncertain, which may result in poor stability of the lamp base and make the lamp prone to tipping over.
[0009] Current portable desk lamps use folding or flexible lamp posts. Folding lamps are still quite bulky when folded, making them inconvenient to carry. Flexible lamps, when bent, have an irregular shape, making them difficult to put in a bag, thus resulting in poor portability.
[0010] Currently, there is a type of desk lamp that uses a telescopic lamp post. This telescopic lamp post consists of two parallel metal telescopic rods that extend and retract together. The two metal telescopic rods also serve as wires to electrically connect the lamp head to the base. When the telescopic lamp post is extended, both metal telescopic rods are exposed to the external environment at the same time, making them prone to contact with metal objects simultaneously, which can cause a short circuit and damage the internal circuitry of the lamp.
[0011] Currently, individual power banks, flashlights, and desk lamps often require the entire unit to be discarded if one component fails, resulting in resource waste. Outdoor enthusiasts typically need to carry these items simultaneously, but the combined size of individual power banks, flashlights, and desk lamps is bulky and inconvenient to carry. Furthermore, the individual power supplies of these devices cannot be directly converted, rendering them unusable once one runs out of power, causing inconvenience. Most individual desk lamps and flashlights lack power level indicators, further hindering user experience. Since individual power banks, flashlights, and desk lamps all include charging circuits, batteries, and buttons, and the same applies to individual flashlights, they essentially require additional batteries, charging circuits, buttons, and dimming circuits, increasing costs.
[0012] Currently, there is a combination of a power bank, flashlight, and desk lamp. This combination is small, portable, and low-cost. However, since the parts that only function as a flashlight and desk lamp are not detachable, users have to carry these parts when only using the power bank, reducing portability. In addition, the power bank in this combination has a fixed capacity, which can lead to issues of being too large or too small in different usage scenarios. In order to achieve portability, this combination does not use a desk lamp pole, high-brightness LEDs, or a focusing device, resulting in poor lighting effects for both the flashlight and desk lamp, and it does not have the lighting effects of a high-powered flashlight or reading lamp.
[0013] Currently, some flashlights and power banks have buttons that are conveniently positioned for right-handed use when held in the right hand, making them easy to hold with one hand. However, when held in the left hand, the buttons are not conveniently positioned for left-handed use, which is inconvenient for left-handed users. Summary of the Invention
[0014] This invention provides a modular device that integrates the functions of a power bank, flashlight, and desk lamp, and this device solves all the problems that have arisen in the prior art.
[0015] The technical solution adopted in this invention is:
[0016] This modular device includes a main circuit module, a power supply module, a flashlight module, and a desk lamp module. The main circuit module connects to one power supply module to form a single-capacity portable power bank; the main circuit module connects to two power supply modules to form a double-capacity portable power bank; the main circuit module connects to the flashlight module and one power supply module to form a single-capacity flashlight; the main circuit module connects to the flashlight module and two power supply modules to form a double-capacity flashlight; and the main circuit module connects to one power supply module and one desk lamp module to form a desk lamp.
[0017] The main circuit module includes a first connector and a second connector, both of which can connect to the power supply module and the desk lamp module. The main circuit module also includes a discharge circuit, and the power supply module contains a battery. A first switch and a second switch are respectively installed between the first connector, the second connector, and the input terminal of the discharge circuit. The first switch includes a first PMOS and a second PMOS, which are connected in reverse series. The first switch controls the conduction and cutoff between the first connector and the discharge circuit. The second switch includes a third PMOS and a fourth PMOS, which are connected in reverse series. The second switch controls the conduction and cutoff between the second connector and the discharge circuit.
[0018] The main circuit module includes a charging circuit and a charging interface. The charging interface is used to connect an external power source to power the charging circuit, and it is also used to connect the flashlight module. The power module supplies power to the flashlight module through the charging interface.
[0019] The main circuit module includes an MCU, buttons, and a power indicator LED. The MCU, buttons, and power indicator LED are used to display the remaining power of the single-capacity and double-capacity power banks. The MCU and buttons are also used to switch and dim the single-capacity flashlight, double-capacity flashlight, and desk lamp. The MCU is also used to detect whether the first connector and the second connector are connected to the power module and the desk lamp module. The MCU is also used to detect whether the charging interface is connected to an external power source and the flashlight module. The MCU is also used to control the conduction and cutoff of the first PMOS, the second PMOS, the third PMOS, and the fourth PMOS.
[0020] The first connector and the second connector are respectively located on the front and back of the main circuit module. The front and back of the main circuit module have the same shape. The side shape of the main circuit module is a rounded rectangle. The side shape of the power module includes half a rounded rectangle. The side shape of the single or double capacity power bank is a rounded rectangle.
[0021] The desk lamp module includes a lighting component, a first hinge, a telescopic lamp post, a second hinge, and a drive component. The lighting component is connected to the top of the telescopic lamp post via the first hinge, and the drive component is connected to the bottom of the telescopic lamp post via the second hinge. The lighting component and the drive component can rotate in opposite directions to be parallel to the telescopic lamp post. The first connecting seat and the second connecting seat are located at the middle of both ends of the main circuit module. In the desk lamp, the drive component is perpendicular to the main circuit module and the power supply module. The bottom surfaces of the drive component, the main circuit module, and the power supply module are on the same plane to form the base of the desk lamp, and the base is T-shaped.
[0022] The telescopic desk lamp pole includes an outer telescopic pole and an inner telescopic pole. The inner telescopic pole is located inside the outer telescopic pole. The outer telescopic pole drives the inner telescopic pole to extend and retract together. The outer telescopic pole and the inner telescopic pole are insulated from each other. The outer telescopic pole and the inner telescopic pole each serve as a conductor. The inner telescopic pole can be replaced by a spring wire. The outer telescopic pole drives the spring wire to extend and retract together. At least one conductor is installed inside the spring wire.
[0023] The charging interface is a USB-Type-C female connector, which is located in the center of the side of the main circuit module. There are iron plates at both ends of the power module and a magnetic plate inside the flashlight module. In single or double capacity flashlights, the magnetic plate attracts the iron plate at one end of the power module.
[0024] The beneficial effects of this invention are:
[0025] This invention solves the problems of fixed-capacity portable power banks. The main circuit module connects to one power module to form a single-capacity portable power bank, and the main circuit module connects to two power modules to form a double-capacity portable power bank. The power modules are detachable, so that users can carry an appropriate number of power modules in different usage scenarios without encountering problems of insufficient or excessive portable power bank capacity.
[0026] This invention solves the problem of a portable power bank consisting of a main module and several sub-modules. The main circuit module connects to the power module to form a portable power bank with single or double capacity. The main circuit module does not contain a battery, so users only need to carry the main circuit module and the powered power module when they go out, without having to carry a dead battery, thus improving portability. The main circuit module connects to a desk lamp module and the power module to form a desk lamp, and the main circuit module connects to a flashlight module and the power module to form a flashlight, so users do not need to buy separate flashlights or desk lamps, thus reducing costs.
[0027] This invention solves the problem of power banks composed of charging head modules and battery modules. The main circuit module connects two power modules to form a double-capacity power bank, which is sufficient to fully charge high-capacity devices such as iPads, eliminating the need for users to replace power modules mid-charge. When multiple power modules need charging, the main circuit module can connect two power modules simultaneously, charging both at once, reducing the number of times power modules need to be replaced mid-charge and eliminating the need for charging docks that can charge multiple battery modules at the same time, thus reducing costs. The main circuit module can also connect to a desk lamp module and a power module to form a desk lamp, or connect to a flashlight module and a power module to form a flashlight, eliminating the need for users to purchase separate flashlights or desk lamps, further reducing costs.
[0028] This invention solves the problem of combining a flashlight and a power bank. The flashlight module is connected to a single or double capacity power bank to form a flashlight. The flashlight module is detachable, so users do not need to carry the flashlight module when they only need the single or double capacity power bank, thus improving portability.
[0029] This invention solves the problem of USB flashlight heads. The flashlight module connects to a single or double capacity power bank to form a flashlight. The buttons and MCU within the main circuit module are used to display the power level of the single or double capacity power bank, and also for the flashlight's on / off and dimming functions. This eliminates the need for separate buttons and dimming circuits on the flashlight module, reducing costs. The charging interface of the main circuit module connects to the external power source and the flashlight module, eliminating the need for a separate interface for connecting the flashlight module, resulting in a more aesthetically pleasing design and avoiding the use of the USB output port on the main circuit module. Users can... It can be used as both a flashlight and a power bank. Since the flashlight module and the single-capacity power bank are designed together, the single-capacity power bank serves as the handheld part of the flashlight, with a rounded rectangular shape on the side. The flashlight weighs less than 200g, and its shape and weight are suitable for holding and are also more aesthetically pleasing. Because there are iron plates at both ends of the power module and a magnet inside the flashlight module, when the flashlight module is connected to the single or double-capacity power bank, the magnet in the flashlight module attracts the iron plate at one end of the power module, making the flashlight module less likely to fall off.
[0030] This invention solves the problem of combining a desk lamp and a power bank. The desk lamp module is connected to a single-capacity power bank to form a desk lamp. The desk lamp module is detachable, so users do not need to carry the desk lamp module when using only the single-capacity power bank, thus improving portability.
[0031] This invention solves the problem of USB desk lamp heads. The desk lamp module connects to a single-capacity power bank to form a desk lamp. The buttons and MCU on the main circuit module are used to display the remaining power of the power module and also for turning the desk lamp on and off and dimming it. This eliminates the need for separate buttons and dimming circuits on the desk lamp module, reducing costs. The buttons on the main circuit module are conveniently located for users and are also more aesthetically pleasing. The desk lamp module connects to the single-capacity power bank via a first or second connector without occupying the power bank's USB output port, allowing users to use both the desk lamp and power bank functions simultaneously. The desk lamp module includes a lighting component, a first hinge, a telescopic lamp post, a second hinge, and a drive component. The bottom surfaces of the drive component, main circuit module, and power module are on the same plane, forming the base of the desk lamp. The first and second connectors are located on the front and back of the main circuit module, respectively, at the midpoint between the two ends. The drive component is located at the midpoint between the two ends of the single-capacity power bank. The base of the desk lamp is T-shaped, making it less prone to tipping over.
[0032] This invention solves the problem of inconvenience of folding and flexible desk lamps. The desk lamp module of this invention adopts a telescopic lamp pole. The telescopic lamp pole adopts a design with an inner telescopic rod or spring wire inside the outer telescopic rod, which makes full use of the space inside the outer telescopic rod. Under the same extension length, the telescopic lamp pole is smaller in volume after shrinking and is more portable.
[0033] This invention solves the problem of a desk lamp pole composed of two parallel metal telescopic rods. The telescopic desk lamp pole of this invention adopts a design with an inner telescopic rod or spring wire inside the outer telescopic rod. The outer telescopic rod drives the inner telescopic rod and spring wire to extend and retract together. The outer telescopic rod, inner telescopic rod, and spring wire act as conductors. Regardless of whether the telescopic desk lamp pole is in an extended or retracted state, only the outer telescopic rod is exposed to the external environment and will not short-circuit due to contact with external metal objects.
[0034] This invention solves the problems of standalone power banks, flashlights, and desk lamps. The main circuit module connects to the power module to form a single or double capacity power bank; the main circuit module connects to the power module and the flashlight module to form a single or double capacity flashlight; and the main circuit module connects to the power module and the desk lamp module to form a desk lamp. When a module fails, it only needs to be disassembled and replaced, instead of being discarded entirely, thus saving resources. Since the main circuit module, flashlight module, and desk lamp module are all powered by the power module, as long as the power module has power, the power bank, flashlight, and desk lamp functions of this device can be used. The circuit module, flashlight module, and desk lamp module are all powered by the power module. The remaining power displayed by the power bank is the remaining power of the flashlight and desk lamp, solving the problem that most standalone desk lamps and flashlights do not have a power display. Each standalone power bank, flashlight, and desk lamp includes a total of three batteries, three charging circuits, two dimming circuits, and three buttons, while the main circuit module, power module, flashlight module, and desk lamp module together include one battery, one charging circuit, one dimming circuit, and one button. This invention achieves three functions while reducing costs, making it smaller and more portable.
[0035] This invention solves the problem of combining a flashlight, a desk lamp, and a power bank. The main circuit module and the power module form a single- or double-capacity power bank. The main circuit module connects to the power module and the flashlight module to form a single- or double-capacity flashlight. The main circuit module connects to the power module and the desk lamp module to form a desk lamp. The flashlight and desk lamp modules are detachable, so when the user only uses the power bank, they do not need to carry the flashlight and desk lamp modules, improving portability. In the single- or double-capacity power bank, the power module is detachable, allowing the user to carry an appropriate number of power modules according to different usage scenarios, avoiding the problem of excessive or insufficient power bank capacity. The desk lamp module adopts a telescopic lamp post design, making it small and easy to carry. The flashlight module uses a focusing device and high-brightness LEDs to achieve strong illumination. Because the flashlight module is detachable, it does not reduce the portability of the single- or double-capacity power bank.
[0036] This invention solves the problem that the button positions of some flashlights, desk lamps, and power banks are inconvenient for left-handed users. Since the first and second connectors are respectively located on the front and back of the main circuit module, and the first and second connectors are located in the middle of both ends of the main circuit module, the front and back of the main circuit module are the same. The side shape of the main circuit module adopts a rounded rectangle design with left and right symmetry, and the side shape of the power module adopts a semi-rounded rectangle design. The USB-Type-C charging port is located in the center of the side of the main circuit module. The power bank, flashlight, and desk lamp each have two combination methods, which can meet the usage habits of both left-handed and right-handed users. Attached Figure Description

The desk lamp connector 39 is provided with a first contact 40, a second contact 41, a third contact 42, a fourth contact 43, and a fifth contact 44. When the power connector 21 is connected to the front connector 6, the first, second, third, fourth, and fifth power contacts are electrically connected to the first, second, third, fourth, and fifth front contacts, respectively. When the power connector 21 is connected to the back connector 12, the first, second, third, fourth, and fifth power contacts are electrically connected to the first, second, third, fourth, and fifth back contacts, respectively. When the desk lamp connector 39 is connected to the front connector 6, the first, second, third, fourth, and fifth desk lamp contacts are electrically connected to the first, second, third, fourth, and fifth front contacts, respectively. When the desk lamp connector 39 is connected to the back connector 12, the first, second, third, fourth, and fifth contacts of the desk lamp are electrically connected to the first, second, third, fourth, and fifth contacts on the back, respectively.
[0074] like Figure 30 As shown, a battery is provided in the power module 2. The first power contact 22 is electrically connected to the positive terminal of the battery, the second power contact 23 and the fifth power contact 26 are electrically connected to the negative terminal of the battery, and the third power contact 24 and the fourth power contact 25 are suspended.
[0075] like Figure 31 As shown, the desk lamp module 4 is equipped with a desk lamp LED and a desk lamp driver circuit. The positive and negative output terminals of the desk lamp driver circuit are electrically connected to the positive and negative terminals of the desk lamp LED, respectively. The first contact 40 of the desk lamp is electrically connected to the positive input terminal of the desk lamp driver circuit. The fourth contact 43 and the fifth contact 44 of the desk lamp are electrically connected to the negative input terminal of the desk lamp driver circuit. The third contact 42 of the desk lamp is electrically connected to the dimming terminal of the desk lamp driver circuit. The second contact 41 of the desk lamp is suspended.
[0076] like Figure 32 and Figure 33 As shown, the main circuit module 1 contains an MCU and first, second, and third diodes. The main circuit module 1 also contains a charging circuit and a boost circuit. The positive terminals of the first, second, and third diodes are electrically connected to the Vin+ terminal of the charging circuit, the first contact 7 on the front, and the first contact 13 on the back, respectively. The negative terminals of the first, second, and third diodes are all electrically connected to the VCC pin of the MCU. The fifth contact 11 on the front, the fifth contact 17 on the back, the GND terminal of the charging circuit, the GND terminal of the boost circuit, and the GND terminal of the MCU are all electrically connected together. The power supply module 2 and the external power supply connected to the front connector 6 and the back connector 12 can both supply power to the MCU.
[0077] like Figure 32 and Figure 33As shown, a first PMOS and a second PMOS are electrically connected between the Vout+ terminal of the charging circuit and the first contact 7 on the front side. The first and second PMOS are connected in reverse series to form a bidirectional switch. The gates of the first and second PMOS are both electrically connected to the first level output pin of the MCU. The MCU controls the conduction and cutoff of the charging circuit and the first contact 7 on the front side by controlling the level of the first level output pin. A third PMOS and a fourth PMOS are electrically connected between the Vout+ terminal of the charging circuit and the first contact 13 on the back side. The third and fourth PMOS are connected in reverse series to form a bidirectional switch. The gates of the third and fourth PMOS are both electrically connected to the second level output pin of the MCU. The MCU controls the conduction and cutoff of the charging circuit and the first contact 13 on the back side by controlling the level of the second level output pin.
[0078] like Figure 32 and Figure 33 As shown, the main circuit module 1 is equipped with LED18, which is electrically connected to the MCU to display the remaining power of the power module 2. The first and second voltage detection pins of the MCU are electrically connected to the first contact 7 on the front and the first contact 13 on the back, respectively. The first voltage detection pin is used to detect the voltage of the power module 2 connected to the front connector 6, and the second voltage detection pin is used to detect the voltage of the power module 2 connected to the back connector 12. The MCU converts the voltage of the power module 2 into the remaining power.
[0079] like Figure 32 and Figure 33 As shown, the front second contact 8 and the back second contact 14 are electrically connected to the first and three-level detection pins of the MCU, respectively. Figure 30 As shown, since the second power contact 23 is electrically connected to the negative terminal of the battery, when the front connector 6 is connected to the power module 2, the MCU will detect a low level on the first level detection pin. When the rear connector 12 is connected to the power module 2, the MCU will detect a low level on the third level detection pin.

When the desk lamp module 4 is connected to the front connector 6, the MCU will detect a low level on the second level detection pin. When the desk lamp module 4 is connected to the back connector 12, the MCU will detect a low level on the fourth level detection pin.

The RX1+, RX1-, RX2+, and RX2- pins of the USB-Type-C male connector 49 are electrically connected to the Vin+ terminal of the flashlight driver circuit, and the GND of the USB-Type-C male connector 49 is electrically connected to the Vin- terminal of the flashlight driver circuit. Figure 33 and Figure 34As shown, the RX1+, RX1-, RX2+, and RX2- pins of the USB-Type-C female connector 19 are electrically connected to the Vout+ terminal of the charging circuit. The GND, the fifth contact 11 on the front, and the fifth contact 17 on the back of the USB-Type-C female connector 19 are electrically connected together. When the flashlight module 3 is connected to the main circuit module 1, the power module 2 can supply power to the flashlight module 3.
[0085] like Figure 32 and Figure 34 As shown, the TX1+ and TX2+ pins of the USB-Type-C female connector 19 are electrically connected to the sixth level detection pin of the MCU, as follows. Figure 35 As shown, since the TX1+, TX2+, and GND pins of the USB-Type-C male connector 49 are electrically connected together, as long as the MCU has a power input, when the flashlight module 3 is connected to the main circuit module 1, the MCU will detect a low level on the sixth level detection pin. The MCU determines whether the flashlight module 3 is connected to the main circuit module 1 by detecting the level of the sixth level detection pin.
[0086] like Figure 35 As shown, the TX1- and TX2- pins of the USB-Type-C male connector 49 are electrically connected to the dimming terminal of the flashlight driver circuit, as follows. Figure 32 and Figure 34 As shown, the TX1- and TX2- pins of the USB-Type-C female connector 13 are electrically connected to the second PWM output pin of the MCU. When the flashlight module 3 is connected to the main circuit module 1, the second PWM output pin outputs a PWM signal to realize the switching and dimming of the flashlight module 3.
[0087] When the MCU detects that the first level detection pin is low, and the third, fourth, and sixth level detection pins are not low, such as Figure 2 As shown, the MCU determines that the front connector 6 is connected to the power module 2 to form a first single-capacity mobile power supply. Figure 33 As shown, the first level output pin of the MCU is low, and the first and second PMOS are turned on to realize the charging and discharging of the power module 2. When button 5 is pressed, the MCU detects the voltage of the first voltage detection pin and displays the remaining power of the power module 2 for 1 second. When button 5 is pressed again, the remaining power is displayed again.
[0088] When the MCU detects that the third level detection pin is low, and the first, second, and sixth level detection pins are not low, such as Figure 3 As shown, the MCU determines that the power module 2 is connected to the rear connector 12 to form a second single-capacity mobile power supply. Figure 33As shown, the second level output pin of the MCU is low, and the third and fourth PMOS are turned on to realize the charging and discharging of the power module 2. When button 5 is pressed, the MCU detects the voltage of the first voltage detection pin and displays the remaining power of the power module 2 for 1 second. When button 5 is pressed again, the remaining power is displayed again.
[0089] When the MCU detects that the first and third level detection pins are low, and the sixth level detection pin is not low, such as Figure 4 As shown, the MCU determines that both the front connector 6 and the back connector 12 are connected to power modules 2 to form a double-capacity mobile power supply. Figure 33 As shown, the MCU detects the level of the fifth level detection pin and the voltages of the first and second voltage detection pins to determine whether there is a charging input and the remaining power of each of the two power modules 2: If the MCU detects a charging input and neither power module 2 is fully charged, the MCU turns on the first and second PMOS transistors to charge the power module 2 connected to the front connector 6 until the MCU detects that it is fully charged; if the MCU detects a charging input and one power module 2 is fully charged, the MCU turns on the corresponding PMOS transistor to charge the power module 2 that is not fully charged until the MCU detects that both power modules 2 are fully charged; if the MCU detects a charging input and both power modules 2 are fully charged, the MCU turns on the first, second, third, and fourth PMOS transistors to stop charging; if the MCU detects no charging input and no charging input, the MCU turns on the first and second PMOS transistors to stop charging; if the MCU detects no charging input and no charging input, the MCU turns on the first and second PMOS transistors to stop charging. When charging input is available and both power modules 2 are powered, the MCU turns on the first and second PMOS transistors, discharging the power module 2 connected to the front connector 6 until the MCU detects that it is de-powered. If the MCU detects no charging input and only one power module 2 is powered, the MCU turns on the corresponding PMOS transistors, discharging the powered power module 2 until the MCU detects that both power modules 2 are de-powered. If the MCU detects no charging input and both power modules 2 are de-powered, the MCU turns on the first, second, third, and fourth PMOS transistors to stop discharging. Pressing button 5 first displays the remaining power of the power module 2 connected to the front connector 6 for 1 second, then after a 1-second interval, displays the remaining power of the power module 2 connected to the rear connector 12 for 1 second. Pressing button 5 again displays the remaining power again.
[0090] When the MCU detects that the first and fourth level detection pins are low, and the sixth level detection pin is not low, such as Figure 13 As shown, the MCU determines that the front connector 6 and the back connector 12 are respectively connected to the power module 2 and the lamp module 4 to form the first lamp. Figure 33As shown, when the first and second level output pins of the MCU are low, the first, second, third, and fourth PMOS are turned on, the power module 2 charges and discharges normally, and simultaneously supplies power to the desk lamp module 4. Pressing button 5 displays the remaining power of the power module 2. Pressing the button again within a 2-second interval will adjust the duty cycle of the PWM output from the first PWM output pin each time button 5 is pressed, thus turning the desk lamp on and off and dimming it. If the time interval between pressing the button exceeds 2 seconds, pressing the button again will display the remaining power again.
[0091] When the MCU detects that the second and third level detection pins are low, and the sixth level detection pin is not low, such as Figure 15 As shown, the MCU determines that the front connector 6 and the back connector 12 are respectively connected to the lamp module 4 and the power module 2 to form a second lamp. Figure 33 As shown, when the first and second level output pins of the MCU are low, the first, second, third, and fourth PMOS are turned on, the power module 2 charges and discharges normally, and simultaneously supplies power to the desk lamp module 4. Pressing button 5 displays the remaining power of the power module 2. Pressing the button again within a 2-second interval will adjust the duty cycle of the PWM output from the first PWM output pin each time button 5 is pressed, thus turning the desk lamp on and off and dimming it. If the time interval between pressing the button exceeds 2 seconds, pressing the button again will display the remaining power again.
[0092] When the MCU detects that the first and sixth level detection pins are low, and the third and fourth level detection pins are not low, such as Figure 5 As shown, the MCU determines that flashlight module 3 is connected to the first single-capacity mobile power supply to form the first flashlight, as follows. Figure 33 As shown, pressing button 5 displays the remaining power of power module 2. Pressing the button again within a 2-second interval will adjust the duty cycle of the PWM output from the second PWM output pin, thus enabling the first flashlight to be switched on and off and dimmed. If the time interval between pressing the button exceeds 2 seconds, pressing the button again will display the remaining power again.
[0093] When the MCU detects that the third and sixth level detection pins are low, and the first and second level detection pins are not low, such as Figure 6 As shown, the MCU determines that flashlight module 3 is connected to the second single-capacity mobile power supply to form a second flashlight, as follows. Figure 33 As shown, pressing button 5 displays the remaining power of power module 2. Pressing the button again within a 2-second interval will adjust the duty cycle of the PWM output from the second PWM output pin, thus enabling the second flashlight to be switched on and off and dimmed. If the time interval between pressing the button exceeds 2 seconds, pressing the button again will display the remaining power again.
[0094] When the MCU detects that the first, third, and sixth signals are low, such as Figure 7As shown, the MCU determines that flashlight module 3 is connected to a double-capacity power bank to form a third flashlight, as... Figure 32 As shown, pressing button 5 first displays the remaining power of the power module 2 connected to the front connector 6, then displays the remaining power of the power module 2 connected to the rear connector 12. Pressing the button again within a 2-second interval will adjust the duty cycle of the PWM output from the second PWM output pin, thus enabling the third flashlight to be switched on and off and dimmed. If the time interval between pressing the button exceeds 2 seconds, pressing the button again will reset the remaining power display.
[0095] When the MCU detects that the first, fourth, and sixth level detection pins are all low, the MCU determines that the flashlight module 3 is connected to the first lamp; when the MCU detects that the second, third, and sixth level detection pins are all low, the MCU determines that the flashlight module 3 is connected to the second lamp; pressing button 5 displays the remaining power of the power module 2. Pressing the button again within a 2-second interval will adjust the duty cycle of the PWM output from the first and second PWM output pins each time button 5 is pressed, thus simultaneously turning the flashlight and lamp on and off and dimming them. If the time interval exceeds 2 seconds, pressing the button again will display the remaining power again.

The top fixing structure 35 fixes the innermost hollow metal rods of the outer telescopic rod 36 and the inner telescopic rod 37 together, and the bottom fixing structure 38 fixes the outermost hollow metal rods of the outer telescopic rod 36 and the inner telescopic rod 37 together. The outer telescopic rod 36 thus drives the inner telescopic rod 37 to extend and retract together. The outer telescopic rod 36 and the inner telescopic rod 37 are insulated from each other. Since there is electrical conductivity between the innermost and outermost hollow metal rods of the outer telescopic rod 36 and the inner telescopic rod 37, each of the outer telescopic rod 36 and the inner telescopic rod 37 acts as a conductor.
[0097] like Figure 25 and Figure 31As shown, the desk lamp LED is housed in the lighting assembly 31, and the desk lamp driving circuit is housed in the driving assembly 34.

[0101] like Figure 28 As shown, the flashlight module 3 includes a flashlight cover 45, a flashlight screw 46, a flashlight fixing plate 47, and a circular magnet 48. The flashlight screw 46, in conjunction with the flashlight fixing plate 47, secures the circular magnet 48 within the flashlight module 3. The flashlight cover 45 covers the surface of the flashlight fixing plate 47 for aesthetic purposes. Figure 24 As shown, each end of the power module 2 is provided with a cover plate 27, a screw 28, and an iron fixing plate 29. The screw 28 fixes the iron fixing plate 29 to both ends of the power module 2, and the cover plate 27 covers the surface of the iron fixing plate 29 for aesthetic purposes; Figure 5 , Figure 6 , Figure 7 As shown, in the first, second, and third flashlights, the circular magnet 48 in the flashlight module 3 attracts the iron fixing piece 29 at one end of the power module 2, so that the flashlight module 3 is attached to the power module 2 and is not easy to fall off.
[0102] like Figure 17 , Figure 18 As shown, the front connector 6 and the back connector 12 are respectively located at the middle of the front and back ends of the main circuit module 1, as... Figure 14 , Figure 16 As shown, the bottom surfaces of the drive assembly 34, main circuit module 1, and power supply module 2 are on the same plane.

Figure 13 , Figure 15 As shown, the drive component 34 is perpendicular to the main circuit module 1 and the power supply module 2. The first and second lamp bases are shaped like a "⊥", which makes the lamps more stable and less likely to fall over.
