[0029] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0030] In the description of the embodiments of the present application, unless otherwise expressly specified or limited, technical terms such as "installed," "connected," "connect," and "fixed" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; internal connections between two components or interactions between two components. Those skilled in the art can understand the specific meanings of the above terms in the embodiments of the present application based on specific circumstances.

[0031] An embodiment of the present application provides a compact mobile power supply. Figure 4 、 Figure 5 and Figure 6 The mobile power supply includes a circuit board 10 and a display digital tube 20.

[0032] The display digital tube 20 includes a tube body 21 and pins 22 extending from the tube body 21. The tube body 21 has a display screen 211. The tube body 21 is arranged on the circumferential side of the circuit board 10 so that the display screen 211 intersects with the board surface of the circuit board 10. The pins 22 are electrically connected to the circuit board 10.

[0033] Specifically, the display digital tube 20 refers to a component connected to the circuit board 10 and capable of displaying information such as power level and charging status.

[0034] The tube body 21 refers to the main part of the display digital tube 20, including a display screen 211 for displaying information.

[0035] The display screen 211 includes a plurality of LEDs (light emitting diodes) for displaying information such as power level and charging status.

[0036] The circuit board 10 is also called a printed circuit board 10 (PCB), and is a supporting substrate for electronic components such as the display digital tube 20 , on which circuit traces and electronic components are arranged.

[0037] The pins 22 are also called leads, and are used to electrically connect the tube body 21 to the circuit board 10 .

[0038] The display digital tube 20 can be arranged on different sides of the circuit board 10 , and the specific position is determined according to actual conditions.

[0039] The manner in which the pins 22 are arranged on the circuit board 10 is not limited.

[0040] For example, the pins 22 are soldered on the circuit board 10 .

[0041] For example, a portion of the circuit board has multiple through-holes 10b, and the display digital tube 20 includes multiple pins 22, which are disposed in a one-to-one correspondence within the through-holes 10b. Therefore, by disposing the pins 22 within the through-holes 10b, the assembly process of the display digital tube 20 and the circuit board 10 is simplified, the connection stability between the display digital tube 20 and the circuit board 10 is improved, and the possibility of poor contact is reduced.

[0042] Specifically, the through-hole 10 b refers to a small hole prefabricated on the circuit board 10 for passing the pin 40 to achieve circuit connection.

[0043] The number of through-holes 10b and pins 22 is not limited, as long as the number of pins 22 is the same as the number of through-holes 10b and corresponds one-to-one. For example, the number of through-holes 10b and pins 22 is one, and pins 22 are disposed within through-holes 10b. Another example is that the number of through-holes 10b and pins 22 is two or more, and pins 22 are disposed one-to-one within through-holes 10b.

[0044] The size of the through hole 10 b is not limited, as long as the pin 22 can pass through and be fixed on the circuit board 10 .

[0045] The tube body 21 is arranged on a circumferential side of the circuit board 10 , that is, the display digital tube 20 is installed at an edge of the circuit board 10 rather than being directly located on the top or bottom of the circuit board 10 .

[0046] The display screen 211 intersects with the surface of the circuit board 10 , that is, the display screen 211 is installed at a certain angle or perpendicular to the circuit board 10 , rather than being parallel to the surface of the circuit board 10 .

[0047] In the related art, power banks typically use an indicator light to indicate battery charge, but this approach offers poor display quality. Furthermore, some power banks employ a digital tube display flush with the circuit board to indicate battery charge. However, this layout occupies a significant amount of space on the circuit board, further increasing the size of the power bank.

[0048] The embodiment of the present application provides a compact mobile power supply, comprising a circuit board 10 and a display digital tube 20. The display digital tube 20 comprises a tube body 21, and pins 22 extending from the tube body 21. The tube body 21 has a display screen 211. The tube body 21 is arranged on the circumferential side of the circuit board 10 so that the display screen 211 intersects with the board surface of the circuit board 10, and the pins 22 are electrically connected to the circuit board 10. Therefore, on the one hand, by arranging the display digital tube 20 on the mobile power supply, not only can the power information be clearly displayed, but also the overall display effect can be improved. On the other hand, arranging the display digital tube 20 on the side of the circuit board 10 helps to optimize the utilization of the internal space, making the power supply structure more compact, thereby reducing the overall size of the mobile power supply and making it more portable.

[0049] In one embodiment, please refer to Figure 4 and Figure 7 The pins 22 are led out from the side of the tube body 21 away from the display screen 211 and bent toward the side closer to the screen to electrically connect to the circuit board 10. Thus, by leading the pins 22 out from one side of the tube body 21 and bending them, the space occupied by the display digital tube 20 can be reduced, making the design of the mobile power supply more compact.

[0050] Specifically, the bending angle of the pin 22 is not limited, and it can be bent at different angles according to the shape of the product, as long as the display screen 211 can intersect with the board surface of the circuit board 10 and be electrically connected to the circuit board 10.

[0051] For example, the bending angle of the pins 22 is 90°, and the display screen is arranged perpendicular to the surface of the circuit board 10. Thus, the internal space of the mobile power supply is effectively utilized and the volume of the mobile power supply is reduced.

[0052] In one embodiment, please refer to Figure 5 Part of the circumferential side of the circuit board 10 is recessed to form a receiving groove 10a, and at least a portion of the display tube 20 is located within the receiving groove 10a. Thus, by designing the receiving groove 10a on the side of the circuit board 10, on the one hand, space can be effectively utilized, making the internal structure of the mobile power bank more compact and further reducing the overall size of the mobile power bank. On the other hand, the receiving groove 10a limits the position of the display tube 20, preventing it from shifting during assembly.

[0053] Specifically, the receiving groove 10 a can be designed to have different shapes and sizes according to the size and shape of the display digital tube 20 to ensure that the display digital tube 20 can be properly placed in the groove.

[0054] At least a portion of the display digital tube 20 is located in the receiving groove 10a, which means that the display digital tube 20 may be partially located in the receiving groove 10a and another portion protrudes from the receiving groove 10a. Alternatively, the entire display digital tube 20 may be located in the receiving groove 10a.

[0055] In one embodiment, please refer to Figure 1 、 Figure 2 and Figure 3 The power bank includes a housing 30 and a plug 40 rotatably mounted on the housing 30. This eliminates the need for a data cable and allows users to plug the power bank directly into their phone, eliminating the inconvenience of carrying a data cable. Furthermore, rotating the plug 40 reduces damage to the pin 40, thereby extending the power bank's service life.

[0056] Specifically, the housing 30 refers to an external protective structure of the mobile power supply.

[0057] Pin 40 refers to a connector for connecting to an interface of other devices, enabling the mobile power supply to charge other devices.

[0058] The pin 40 can be rotated by different mechanical structures, such as a rotating hinge or a slide rail.

[0059] In one embodiment, please refer to Figure 1 、 Figure 2 and Figure 3 The housing 30 is partially recessed to form a rotation slot 30a, and the pin 40 is rotatably disposed in the rotation slot 30a. Thus, the pin 40 is rotatably disposed in the rotation slot 30a formed in the housing 30, making the mobile power supply more compact and easy to carry and store.

[0060] Specifically, the rotation groove 30 a refers to a recessed portion of the housing 30 for accommodating the pins 40 .

[0061] The rotation slot 30 a can be designed according to the size and shape of the pin 40 to ensure that the pin 40 can rotate smoothly and be stably fixed.

[0062] It is understandable that in order to ensure that the pin 40 can be stably fixed when it is rotated to a specific position, the rotation slot 30a may include a limiting structure, such as a protrusion or a groove, to prevent the pin 40 from rotating accidentally.

[0063] In one embodiment, please refer to Figure 1 、 Figure 2 and Figure 3 The pin 40 has a folded position within the rotation slot 30a and an extended position perpendicular to the slot 30a. The pin 40 rotates to switch between the folded and extended positions. This allows the pin 40 to be perpendicular to the slot 30a when the power bank is in use, facilitating connection between the pin 40 and the device being charged. Furthermore, when the power bank is not in use, the pin 40 remains within the rotation slot 30a, preventing damage to the pin 40 and preventing scratches or other damage to the external structure.

[0064] Specifically, the folded state refers to the state in which the pin 40 is stored in the rotating groove 30a and does not protrude from the housing 30. In this state, the pin 40 can be protected from damage, and the mobile power supply is more convenient to carry and store.

[0065] The extended state refers to the state in which the pin 40 of the mobile power supply extends from the rotation slot 30a and protrudes from the housing. In this state, the pin 40 can be easily aligned with the charging port of the device that needs to be charged, thereby achieving quick connection.

[0066] In one embodiment, please refer to Figure 6 The sidewalls on opposite sides of the rotation slot are provided with rotation openings. Partial areas on opposite sides of the pins 40 protrude to form rotation axes 41. The rotation axes 41 are rotatably inserted into the rotation openings in a one-to-one correspondence. Thus, the pins 40 rotate about the rotation axes 41 to switch between the folded and extended states.

[0067] Specifically, the rotation shaft 41 is disposed in the opening of the rotation slot 30 a so that the pin 40 can rotate within a certain angle range.

[0068] In one embodiment, please refer to Figure 1The mobile power supply includes a housing 30, a portion of which is provided with a display port 30b, and a display screen 211 is located within the display port 30b. Thus, by providing the display port 30b, a user can easily obtain information such as the power level and charging status of the mobile power supply.

[0069] Specifically, the display port 30 b refers to an opening on the housing 30 , which is used to display the display screen 211 and allow the user to view information on the display screen 211 , such as the battery level, charging status, etc.

[0070] The size and shape of the display opening 30b are not limited. According to the size and shape of the display screen, the display opening 30b can be designed into different sizes and shapes to ensure that the display screen 211 can be properly displayed.

[0071] The position of the display port 30 b on the housing 30 is not limited.
