Description

Technical Field

[0001] The present invention relates to the technical field of portable charging power supplies, and in particular to a mobile power supply. Background Art

[0002] A power bank is a portable charger that can be carried around by individuals and stores energy, allowing them to power other appliances. It's particularly useful in situations where there's no external power supply. Its main components include a battery for storing energy and a circuit (DC-DC converter) for stabilizing the output voltage. Most power banks come with a charger to charge the internal battery.

[0003] On the one hand, most existing mobile power supplies use non-removable batteries, which have a limited lifespan, resulting in limited replaceability. On the other hand, existing mobile power supplies typically use standard batteries with separate positive and negative electrodes. These batteries typically require a conductive aluminum alloy or other metal body and tail to allow the positive and negative electrodes to be extracted. This limits their size, weight, and cost.

[0043] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the present invention.

[0044] See also Figure 1 and Figure 2 The present invention provides a mobile power supply, including a housing 10 and a PCB board 20, a fixing member 30, a positive electrode connector 40, a negative electrode connector 50 and an elastic telescopic member 60 arranged in the housing.

[0045] The PCB board 20 serves as the main circuit board of the mobile power supply and is provided with a discharge circuit (not shown), a positive electrode (not shown), a negative electrode (not shown), and an output interface 23. The positive electrode, the negative electrode, and the output interface 23 are respectively connected to the discharge circuit. The discharge circuit is used to connect to the positive and negative electrodes of the battery via the positive and negative electrodes and discharge through the output interface 23. In other examples, the PCB board 20 may also be provided with a charging and discharging circuit. In the embodiment of the present invention, the output interface 23 on the PCB board 20 is a Type-C interface. In other embodiments, it may also be one or more other interfaces, such as a micro-USB interface, a mini-USB interface, a Dock interface, and a Lightning interface.

[0046] like Figure 1 As shown, the housing 10 is provided with an opening 12 for accommodating the output interface 23 .

[0047] The fixing member 30 is disposed below the PCB board 20 . Both ends of the elastic member 60 are fixedly connected to the fixing member 30 . The elastic member 60 and the bottom of the fixing member 30 together form a battery installation area 61 .

[0048] The lower end of the positive electrode connector 40 is set at the bottom of the fixing member 30, the upper end of the positive electrode connector 40 passes through the fixing member 30 and is connected to the positive electrode, and the lower end of the negative electrode connector 50 is set at the bottom of the fixing member 30, the upper end of the negative electrode connector 50 passes through the fixing member 30 and is connected to the negative electrode.

[0049] The elastic member 60 is used to fix the battery 70 in the battery installation area 61 so that the positive electrode of the battery 70 is connected to the positive electrode connector 40 and the negative electrode of the battery 70 is connected to the bottom of the negative electrode connector 50. Figure 10As shown, the positive electrode 71 and the negative electrode 72 of the battery 70 are located on the same side, that is, the positive electrode 71 and the negative electrode 72 of the battery 70 are fixed to the bottom of the fixing member 30. In the embodiment of the present invention, the elastic member 60 can be a rubber band or other elastic member with elastic expansion function.

[0050] In this embodiment of the present invention, the power bank uses batteries with positive and negative terminals located on the same side and secures the batteries with an elastic member 60, reducing the overall size and weight of the power bank. Furthermore, the batteries are removably mounted in a battery mounting area 61 formed by the elastic member 60 and the securing member 30, allowing for flexible replacement of the batteries as needed, thus increasing convenience.

[0051] The structure of the fixing member 30 and the fixing method between the fixing member 30 and the elastic member 60 can be implemented in many specific ways. Figure 2 The fixing member 30 includes a front pressing plate 32 and a rear pressing plate 31 fixed to each other from top to bottom, and both ends of the elastic telescopic member 60 are respectively fixed between the front pressing plate 32 and the rear pressing plate 31.

[0052] Please also see Figure 3-6 A first groove 321 and a second groove 322 are provided on the front pressure plate 32, a first end 62 of the elastic telescopic member 60 is provided with an upward first protrusion 621, and a second end 63 of the elastic telescopic member 60 is provided with an upward second protrusion 631. When the elastic telescopic member 60 is fixed between the front pressure plate 32 and the rear pressure plate 31, the first protrusion 621 is inserted into the first groove 321, and the second protrusion 631 is inserted into the second groove 322, thereby fixing the elastic telescopic member 60.

[0053] See also Figure 4 and Figure 5 A third downward protrusion 622 is also provided on the first end 62 of the elastic telescopic member 60, and a fourth downward protrusion 632 is also provided on the second end 63 of the elastic telescopic member 60. An annular wall 311 is provided on the rear pressure plate 31. When the elastic telescopic member 60 is fixed between the front pressure plate 32 and the rear pressure plate 31, the third protrusion 622 and the fourth protrusion 632 abut against the inner side of the annular wall 311, thereby fixing the elastic telescopic member 60 between the front pressure plate 32 and the rear pressure plate 31 from the upper and lower directions.

[0054] During use, when a battery is placed in the battery installation area 61 formed by the elastic telescopic member 60 and the fixing member 30, the battery will tighten the elastic telescopic member 60. Under the elastic force of the elastic telescopic member 60, the first end 62 and the second end 63 of the elastic telescopic member 60 are clamped between the front pressure plate 32 and the rear pressure plate 31, so that the battery is fully and reliably wrapped and supported.

[0055] There are also many specific implementations for the fixing of the front pressing plate 32 and the rear pressing plate 31. In one embodiment, see Figure 4 The rear pressure plate 31 is provided with a first positioning column 313 and a second positioning column 314, and the first positioning column 313 and the second positioning column 314 are both provided with threaded holes; Figure 3 The front pressing plate 32 is provided with a first positioning hole 323 and a second positioning hole 324 correspondingly. Figure 2 The two screws pass through the first positioning hole 323 and the second positioning hole 324 respectively, and are tightened into the threaded holes of the first positioning column 313 and the second positioning column 314 respectively, to achieve a fixed connection between the front pressure plate 32 and the rear pressure plate 31.

[0056] The specific structure of the positive electrode connector 40 can be implemented in many ways. In one embodiment, see Figure 7 The positive electrode connector 40 is a contact nail, and an annular flange 41 is provided at the middle and lower part of the contact nail.

[0057] Please also see Figure 3 and Figure 4 A first central opening 325 and a second central opening 315 are respectively provided at the center of the front pressure plate 32 and the rear pressure plate 31. The diameters of the first central opening 325 and the second central opening 315 are larger than the diameter of the contact pin body and smaller than the diameter of the annular flange 41, so that the contact pin can be inserted into the first central opening 325 and the second central opening 315.

[0058] In a preferred embodiment, see Figure 7 and Figure 8 The bottom of the PCB board 20 is provided with a third groove 22 with an opening facing downward, and the positive electrode is provided at the top of the third groove 22. The front end of the contact pin body is provided with a contact portion 42, and the diameter of the contact portion 42 is smaller than the diameter of the contact pin body and the diameter of the third groove 22.

[0059] A spring 80 is sleeved on the body of the contact pin, and a limiting member 90 for limiting the spring 80 is sleeved on the contact portion 42 . The limiting member 90 is sleeved on the contact portion 42 , and the aperture of the limiting member 90 is smaller than the width of the spring 80 .

[0060] When the battery 70 is fixed to the battery mounting area 61 , the positive electrode of the battery 70 presses the contact pin upward, causing the contact pin to overcome the resistance of the spring 80 , and the contact portion 42 enters the third groove 22 to be electrically connected to the positive electrode.

[0061] In the embodiment of the present invention, the spring 80 is clamped between the annular flange 41 of the contact pin and the front pressure plate 32 , which can ensure effective contact between the contact pin and the positive electrode of the battery 70 and the PCB board 20 .

[0062] The specific structure of the negative electrode connector 50 can be implemented in many ways. In one embodiment, see Figure 2 and Figure 7 The negative electrode connector 50 includes an annular metal sheet, which is arranged between the front pressing plate 32 and the rear pressing plate 31.

[0063] A first negative electrode contact post 51 and a second negative electrode contact post 52 are provided on a pair of opposite sides of the bottom of the annular metal sheet, and a first negative electrode lead-out tab 53 and a second negative electrode lead-out tab 54 are provided on a pair of opposite sides of the upper portion of the annular metal sheet.

[0065] The first negative electrode contact post 51 and the second negative electrode contact post 52 pass through the first negative electrode transfer hole 316 and the second negative electrode transfer hole 317 respectively to connect to the negative electrode 72 of the battery 70 .

[0066] The first negative electrode lead-out tab 53 and the second negative electrode lead-out tab 54 pass through the first negative electrode lead-out hole 329 and the second negative electrode lead-out hole 330 respectively and are connected to two negative electrodes disposed on the side surface of the PCB board 20 .

[0067] There are many ways to connect the PCB board 20 and the fixing member 30. In one embodiment, see Figure 3 The front pressing plate 32 is provided with a slot 328 and a first clamping member 326 and a second clamping member 327. Figure 8 , two positioning grooves 21 are provided on both sides of the PCB board 20, which respectively engage with the first clamping member 326 and the second clamping member 327. During installation, the bottom of the PCB board 20 is inserted into the slot 328, and the positioning grooves 21 on both sides of the PCB board 20 are respectively engaged with the first clamping member 326 and the second clamping member 327.

[0069] In a preferred embodiment, the mobile power supply of the present invention further includes at least one indicator light disposed on the surface of the housing 10, the indicator light being connected to the PCB board 20 and being used to indicate the working status of the battery. Preferably, the indicator light is an LED light.

The inner wall of the shell 10 is provided with four connecting parts (not shown), and the four connecting parts are provided with second threaded holes corresponding to the four first threaded holes 312. The first threaded holes 312, the avoidance grooves 331 and the second threaded holes are positioned relative to each other, and the threads of the first threaded holes 312 and the second threaded holes match. During installation, four screws are used to pass through the four first threaded holes 312 of the front pressure plate 32, pass through the four avoidance grooves 331 of the rear pressure plate 31, and finally screw into the second threaded holes on the inner wall of the shell 10, thereby fixing the front pressure plate 32 and the rear pressure plate 31 inside the shell 10.

[0071] In a preferred embodiment, see Figure 9 The outer periphery of the housing 10 is provided with a flange pattern 13, which serves to improve the touch feeling and prevent slipping.
