Description

Technical Field

[0001] The invention relates to the field of mobile power supplies and desk lamps, and in particular to a modular device with the functions of a mobile power supply and a desk lamp. Background Art

[0002] Currently, there is a combination of a desk lamp and a mobile power supply. Since the parts in the combination that are only used for the desk lamp function cannot be disassembled, the user has to carry the parts that are only used for the desk lamp function when only using the mobile power supply, which reduces portability.

[0003] Currently, there is a USB desk lamp head that is connected to the USB output interface of a mobile power supply to form a desk lamp. The mobile power supply serves as a base, and the USB desk lamp head is detachable. Users only need to move the power supply without having to carry the USB desk lamp head, thereby improving portability. However, most USB desk lamp heads do not have a dimming function. The current solution is to set buttons and dimming circuits on the USB desk lamp head, which increases costs, and the button position is inconvenient for users to press, and the overall appearance is not beautiful. Since the USB desk lamp head will occupy a USB output interface, a mobile power supply with only a single USB output interface cannot charge a mobile device at the same time after being connected to the USB desk lamp head, which brings inconvenience to the user. Since the USB desk lamp head and the mobile power supply are designed separately and randomly combined, the stability of the desk lamp base may be very poor, causing the desk lamp to easily fall over.

[0004] The current portable desk lamps use folding and hose-type desk lamp poles. The folding desk lamp is still large in size after being folded, and is not convenient to carry; the hose-type desk lamp has an irregular shape after being bent, and is not convenient to place in a bag, resulting in poor portability.

[0005] Currently, there is a desk lamp that uses a telescopic desk lamp pole. The telescopic desk lamp pole is composed of two parallel metal telescopic rods. The two metal telescopic rods are extended together. The two metal telescopic rods also serve as wires to electrically connect the lamp head and the base. When the telescopic desk lamp pole is in an extended state, the two metal telescopic rods are exposed to the external environment at the same time, and it is easy for them to contact metal objects at the same time, thereby causing a short circuit and damaging the internal circuit of the desk lamp. Summary of the invention

[0006] The present invention provides a modular device with mobile power supply and desk lamp functions, which solves all the problems of the background technology. The technical solution adopted by the present invention is:

[0007] A modular device with mobile power supply and desk lamp functions, comprising a mobile power supply and a desk lamp module. The desk lamp module is connected to the mobile power supply to form a desk lamp. The desk lamp module is detachable. The mobile power supply is provided with a button and an MCU. The button and the MCU are used to display the power level of the mobile power supply. The button and the MCU are also used to switch and dim the desk lamp.

[0008] The mobile power supply is provided with a USB input interface, a USB output interface, a battery, and a connection socket. The MCU is also used to detect whether the connection socket is connected to a desk lamp module.

[0009] The desk lamp module includes a lighting component, a first hinge, a telescopic desk lamp pole, a second hinge, and a driving component. The lighting component is connected to the top end of the telescopic desk lamp pole through the first hinge, and the driving component is connected to the bottom end of the telescopic desk lamp pole through the second hinge. The lighting component and the driving component can rotate toward or against the telescopic desk lamp pole in parallel or in a straight line. In the desk lamp, the driving component is inserted into the connecting seat, and the bottom surfaces of the driving component and the mobile power supply are in the same plane. The driving component and the mobile power supply constitute the base of the desk lamp. The connecting seat is set in the middle of the two ends of the mobile power supply, and the shape of the base is "T".

[0010] The telescopic table lamp pole comprises an outer telescopic pole and an inner telescopic pole, wherein the inner telescopic pole is arranged 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 are each used 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, and at least one conductor is arranged inside the spring wire. The beneficial effects of the present invention are:

[0011] The present invention solves the problem of combining a desk lamp and a mobile power source; a desk lamp module is connected to a mobile power source to form a desk lamp; the desk lamp module can be disassembled; when a user only uses the mobile power source, the user does not need to carry the desk lamp module, thereby improving portability.

[0012] The present invention solves the problem of a USB desk lamp head. A desk lamp module is connected to a mobile power source to form a desk lamp. The buttons and MCU in the mobile power source are used to display the power level of the mobile power source and are also used to switch the desk lamp on and off and dim the light. There is no need to set separate buttons and dimming circuits on the desk lamp module, which reduces the cost. The button positions on the mobile power source are convenient for users to press and are more beautiful. The desk lamp module is connected to the mobile power source through a connecting seat and does not occupy the USB output interface of the mobile power source. The user can use the desk lamp function and the mobile power source function at the same time. The desk lamp module comprises a lighting component, a first hinge, a telescopic desk lamp pole, a second hinge, and a driving component. The driving component is connected to the mobile power source. The bottom surfaces of the driving component and the mobile power source are on the same plane. The driving component and the mobile power source constitute the base of the desk lamp. The driving component is located in the middle of the two ends of the mobile power source. The shape of the desk lamp base is "T", which makes it difficult for the desk lamp to fall over.

[0013] The present invention solves the problem that foldable and hose-type desk lamps are not portable. The desk lamp module of the present invention adopts a telescopic desk lamp pole. The telescopic desk lamp pole adopts a design in which an inner telescopic rod or a spring wire is arranged inside an outer telescopic rod, thereby making full use of the space inside the outer telescopic rod. When the extension length is the same, the volume of the telescopic desk lamp pole after contraction is smaller and more portable.

[0014] The present invention solves the problem of a desk lamp pole composed of two parallel metal telescopic rods. The telescopic desk lamp pole of the present invention adopts a design in which an inner telescopic rod or a spring wire is arranged inside an outer telescopic rod. The outer telescopic rod drives the inner telescopic rod and the spring wire to extend and retract together. The outer telescopic rod, the inner telescopic rod and the spring wire act as a conductor. No matter whether the telescopic desk lamp pole is in an extended or contracted state, only the outer telescopic rod is exposed to the external environment and will not be short-circuited due to contact with external metal objects.

DETAILED DESCRIPTION

[0028] like Figure 1 As shown, the device includes a mobile power source 1 and a desk lamp module 2. After the desk lamp module 2 is unfolded, it is connected to the mobile power source 1 to form a desk lamp.

[0029] like Figure 3 As shown, the mobile power supply 1 is provided with a connection socket 6 for connecting the desk lamp module 2; Figure 4 As shown, the connection base 6 is provided with a first contact member 7, a second contact member 8, a third contact member 9, and a fourth contact member 10; Figure 6 , Figure 8 As shown, the desk lamp module 2 is provided with a driving component 15, and the driving component 15 is provided with a connector 16, as shown in FIG. Figure 7 As shown, the connector 16 is provided with a fifth contact 17, a sixth contact 18, a seventh contact 19, and an eighth contact 20. When the connector 16 is connected to the connector base 6, the first contact 7, the second contact 8, the third contact 9, and the fourth contact 10 are electrically connected to the fifth contact 17, the sixth contact 18, the seventh contact 19, and the eighth contact 20, respectively.

[0030] like Figure 3 As shown, the mobile power supply 1 is provided with a USB charging interface 3, and the USB charging interface 3 is used to connect to an external power source; Figure 5 As shown, the mobile power supply 1 is provided with a USB output interface 11, and the USB output interface 11 is used to charge the mobile device; Fig.10 As shown, the mobile power supply 1 is provided with a battery, a charging circuit, a boost circuit, and an MCU. The Vout+ end of the charging circuit, the Vin+ end of the boost circuit, and the positive electrode of the battery are electrically connected together, and the GND end of the charging circuit, the GND end of the boost circuit, the GND pin of the MCU, and the negative electrode of the battery are electrically connected together. The charging circuit is used to charge the battery, and the battery supplies power to the boost circuit. The first and second diodes are electrically connected between the Vin+ end of the charging circuit, the positive electrode of the battery, and the VCC pin of the MCU, respectively, and both the external power supply and the battery can supply power to the MCU.

[0031] like Fig.11 As shown, the desk lamp module 2 is provided with a desk lamp driving circuit and a desk lamp LED, the Vout+ and Vout- terminals of the desk lamp driving circuit are electrically connected to the positive and negative electrodes of the desk lamp LED respectively, and the Vin+ and Vin- terminals of the desk lamp driving circuit are electrically connected to the fifth contact 17 and the eighth contact 20 of the connector 16 respectively; Fig.10 As shown, the first contact piece 7 and the fourth contact piece 10 of the connection socket 6 are electrically connected to the positive and negative electrodes of the battery respectively. When the desk lamp module 2 is connected to the connection socket 6, the battery supplies power to the desk lamp module 2.

[0032] like Fig.11 As shown, the seventh contact 19 of the connector 16 is electrically connected to the eighth contact 20. Fig.10 As shown, the third contact 9 of the connecting socket 6 is electrically connected to the first level detection pin of the MCU. Since the fourth contact 10 of the connecting socket 6 is electrically connected to the negative pole of the battery, when the desk lamp module 2 is connected to the mobile power supply 1, the eighth contact 20 and the seventh contact 19 are at a low level, and the first level detection pin is thus at a low level. The MCU determines whether the desk lamp module 2 is connected to the mobile power supply 1 by detecting the level of the first level detection pin.

[0033] like Fig.11 As shown, the sixth contact 18 of the connector 16 is electrically connected to the dimming end of the desk lamp driving circuit, as shown in FIG. Fig.10 As shown, the second contact piece 8 of the connecting socket 6 is electrically connected to the PWM output pin of the MCU. When the desk lamp module 2 is connected to the mobile power supply 1, the MCU adjusts the PWM signal of the PWM output pin to realize the switching and dimming of the desk lamp.

[0034] like Figure 3 As shown, the mobile power supply 1 is provided with a power display LED 4 and a button 5. Fig.10 As shown, the positive electrode of the battery is electrically connected to the first voltage detection pin of the MCU for detecting the voltage of the battery. The power display LED 4 and the button 5 are electrically connected to the MCU for displaying the power of the battery. The button 5 is also used for turning the flashlight on and off and dimming. If the desk lamp module 2 is not connected to the mobile power supply 1, press the button 5 to display the power of the mobile power supply 1 for 2 seconds. Continue to press the button to display the power again. If the mobile power supply 1 is connected to the desk lamp module 2, press the button 5 to display the power of the mobile power supply 1 for 2 seconds. Press the button again. If the time interval between the two presses is within 2 seconds, the desk lamp is dimmed or turned on. If the time interval between the two presses exceeds 2 seconds, the remaining power of the mobile power supply 1 is displayed again.

[0035] like Figure 6 , Figure 8 As shown, the desk lamp module 2 includes a lighting component 12, a hinge 13, a telescopic desk lamp pole 14, and a driving component 15. The lighting component 12 and the driving component 15 are respectively connected to the top and bottom ends of the telescopic desk lamp pole 14 through the hinge 13. The lighting component 12 and the driving component 15 can rotate toward or against each other and be parallel to or in a straight line with the telescopic desk lamp pole 14.

[0036] like Fig. 9As shown, the telescopic desk lamp pole 14 includes a top fixing structure 21, a bottom fixing structure 22, an outer telescopic rod 23, and an inner telescopic rod 24. The outer telescopic rod 23 is composed of a rounded rectangular hollow metal rod and a copper sheet, and the inner telescopic rod 24 is composed of a circular hollow metal rod and a copper sheet. The outer telescopic rod 23 and the inner telescopic rod 24 are telescopically extended and retracted using the telescopic principle of a pull-rod antenna. The inner telescopic rod 24 is arranged inside the outer telescopic rod 23. The top fixing structure 21 fixes the innermost hollow metal rods of the outer telescopic rod 23 and the inner telescopic rod 24 together, and the bottom fixing structure 22 fixes the outermost hollow metal rods of the outer telescopic rod 23 and the inner telescopic rod 24 together. The outer telescopic rod 23 thereby drives the inner telescopic rod 24 to retract and retract together. The outer telescopic rod 23 and the inner telescopic rod 24 are insulated from each other. Since the innermost and outermost hollow metal rods of the outer telescopic rod 23 and the inner telescopic rod 24 are conductive, the outer telescopic rod 23 and the inner telescopic rod 24 each serve as a conductor.

[0037] like Figure 8 and Fig.11 As shown, the desk lamp LED is arranged in the lighting assembly 12, the desk lamp driving circuit is arranged in the driving assembly 15, the positive and negative electrodes of the desk lamp LED are respectively electrically connected to the innermost hollow metal rods of the outer telescopic rod 23 and the inner telescopic rod 24, and the positive and negative output ends of the desk lamp driving circuit are respectively electrically connected to the outermost hollow metal rods of the outer telescopic rod 23 and the inner telescopic rod 24, so as to realize the electrical connection between the desk lamp LED and the desk lamp driving circuit. The inner telescopic rod 24 can be replaced by a spring wire, which is arranged inside the outer telescopic rod 23, and the two ends of the spring wire are respectively fixed on the innermost and outermost hollow metal rods of the outer telescopic rod 23, and the outer telescopic rod 23 drives the spring wire to extend and retract together, and at least one conductor is arranged inside the spring wire.

[0038] like Figure 4 As shown, the connection socket 6 is arranged in the middle of both ends of the mobile power supply 1. Figure 1 As shown, in the desk lamp, the driving component 15 is located in the middle of the two ends of the mobile power supply 1, as shown in FIG. Figure 2 As shown, the bottom surfaces of the driving assembly 15 and the mobile power supply 1 are in the same plane and constitute the base of the table lamp. The base of the table lamp is in a "T" shape, and the table lamp is not easy to fall over.

[0039] like Figure 1 As shown, when the desk lamp module 2 is in the unfolded state, the lighting height can reach 37 cm, reaching the lighting height of the reading desk lamp on the market. The lighting assembly 12 can move forward and backward and up and down, and the user can adjust the appropriate lighting range, such as Figure 6 As shown, when the desk lamp module 2 is in the retracted state, its length, width and height are only 14.3cm*1.8cm*2cm, which is small in size and easy to carry.
