[0034] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. Now, in conjunction with the accompanying drawings, a preferred embodiment of the present utility model is described in detail.

[0035] The utility model embodiment provides a mobile power supply, such as Figures 1 to 3 As shown, the mobile power supply includes a shell 1, a circuit board 2, a mounting base 3 and a display module 4; the circuit board 2 is installed in the shell 1, the mounting base 3 is installed in the shell 1 or on the circuit board 2, and the display module 4 is installed on the mounting base 3; the display module 4 is electrically connected to the circuit board 2.

[0036] The mobile power supply of the utility model is provided with a mounting base 3, and the display module 4 is mounted on the mounting base 3. In this way, the mounting base 3 and the display module 4 are modularized. For example, the display module 4 can be mounted on the mounting base 3 before being installed in the housing 1, and then modularly installed in the housing 1, thereby improving the convenience of assembling the mobile power supply. At the same time, the mounting base 3 provides a special mounting position for the display module 4, which can more conveniently install the display module 4, and the fixing of the display module 4 is also more stable and reliable.

[0037] The display module 4 can be used to display information such as the power level and charging status of the mobile power source. The display module 4 can be a liquid crystal display screen, such as a TFT display screen.

[0038] Specifically, Figures 2 to 4 As shown, the mobile power supply also includes a heat sink 10, which is arranged in the housing 1; the mounting base 3 is located on one side of the circuit board 2, and the heat sink 10 is located on the other side of the circuit board 2. During the use of the mobile power supply, the circuit board 2 will generate a certain amount of heat. The heat sink 10 can effectively absorb and disperse the heat, accelerate the heat dissipation, thereby preventing the circuit board 2 from overheating and protecting the safety of other components such as the circuit board 2 and the mobile power supply battery module 9. The mounting base 3 is arranged on one side of the circuit board 2, so that the display module 4 can be separated from the circuit board 2 to prevent the heat generated by the circuit board 2 from directly affecting the display module 4. In this way, the display module 4 can be protected and its service life can be extended. The heat sink 10 is arranged on the other side of the circuit board 2, so that the space inside the mobile power supply can be better utilized, so that the circuit board 2, the mounting base 3 and the heat sink 10 can be more compactly configured in the housing 1. This can not only reduce the volume of the mobile power supply and improve its portability, but also avoid the waste of internal space. The heat sink 10 can be an aluminum sheet, a copper sheet, etc.

[0039] like Figures 2 to 5As shown, the circuit board 2 includes a first circuit board 21 and a second circuit board 22, which are stacked up and down and electrically connected, and the display module 4 is electrically connected to the first circuit board 21. In this solution, the circuit board 2 is divided into a first circuit board 21 and a second circuit board 22. This multi-layer circuit board design allows the mobile power supply to allocate different circuit functions to different circuit boards according to the functional requirements of the circuit, and the circuit design of the mobile power supply is more flexible. The stacking of the first circuit board 21 and the second circuit board 22 effectively reduces the volume of the mobile power supply, making the mobile power supply more compact and portable. Specifically, the first circuit board 21 can be mainly used for circuit connection, power distribution and control of the display module 4 and the power output interface 211. The second circuit board 22 can be mainly used for circuit connection, power distribution and control of the power input interface 222 and the mobile power battery module 9. The power input interface 222 can be a type-C charging port for charging the mobile power supply.

[0040] Specifically, the mounting base 3 is mounted on the first circuit board 21, and the heat sink 10 is mounted on the second circuit board 22. In this solution, the first circuit board 21 and the second circuit board 22 are cleverly used to install the mounting base 3 and the heat sink 10, without the need to introduce additional mounting structures, and the structure is simple. At the same time, after the mounting base 3 and the heat sink 10 are respectively mounted on the first circuit board 21 and the second circuit board 22, the mounting base 3, the heat sink 10, the first circuit board 21, the second circuit board 22 and the display module 4 form a modular system for easy assembly and disassembly. Specifically, the mounting base 3 can be snap-connected to the first circuit board 21 by a buckle, and the heat sink 10 can be welded to the second circuit board 22 by the legs arranged thereon. The first circuit board 21 can be fixed to the studs arranged in the housing 1 by screws.

[0041] like Figure 2 As shown, a heat dissipation space 5 is formed between the heat sink 10 and the second circuit board 22; components are installed on the side of the second circuit board 22 facing the heat sink 10, and the components are located in the heat dissipation space 5. By forming the heat dissipation space 5 between the heat sink 10 and the second circuit board 22, the components on the second circuit board 22 that are prone to heat are located in the heat dissipation space 5, which can improve the heat dissipation efficiency, thereby ensuring the normal operation of the components and extending their service life. This design also optimizes the use of space. The components are directly installed on the side of the circuit board 2 facing the heat sink 10, which not only saves space, but also facilitates the direct transfer of heat and improves the heat dissipation efficiency. The components can be, for example, capacitors, inductors, resistors, etc.

[0042] On the other hand, Figure 5 and Figure 6As shown, the top surface of the mounting base 3 is provided with a mounting groove 31, and the display module 4 is installed in the mounting groove 31. The display module 4 is installed in the mounting groove 31, which can make the display module 4 more firmly installed, and also facilitate the rapid positioning and assembly of the display module 4 on the mounting base 3. By providing the mounting groove 31 on the top surface of the mounting base 3, the internal space can be further effectively utilized, making the mobile power supply more compact. Specifically, the display module 4 can be attached to the mounting groove 31 by double-sided tape.

[0043] like Figure 2 , Figure 3 , Figure 5 , Figure 6 As shown, two opposite first side surfaces 32 of the mounting base 3 are provided with ventilation openings 321, which can improve the air circulation in the mounting base 3, improve the heat dissipation effect of the first circuit board 21, avoid the accumulation of heat generated by the first circuit board 21, and avoid damage to components in the event of overheating.

[0044] A component or power output interface 211 is installed on the side of the first circuit board 21 facing the mounting base 3; two second side surfaces 33 opposite to the mounting base 3 are provided with avoidance openings 331, and the component or power output interface 211 is arranged corresponding to the avoidance openings 331. The avoidance openings 331 can avoid the component or power output interface 211, so as to facilitate the installation of the mounting base 3 and the first circuit board 21. The power output interface 211 can be a type-C or type-A charging port, which supplies power to the outside.

The support protrusion 34 can support the edge of the window 11 to improve the structural stability at the edge of the window 11. A plurality of support protrusions 34 can be provided on the first side 32 and the second side 33. A transparent panel 8 can be further provided at the window 11 to seal the window 11 and protect the display module 4.

The detachable bottom plate 12 facilitates the assembly and disassembly of the circuit board, the mounting base 3, the display module 4 and the heat sink 10. For example, during assembly, the modularized circuit board 2, the mounting base 3, the display module 4 and the heat sink 10 are first assembled and installed in the installation space, then installed into the installation space, and then the bottom plate 12 is installed. The bottom plate 12 can be mounted on the bottom of the housing 1 by snapping. It should be noted that the side of the housing 1 where the display area of ​​the display module 4 is exposed through the window 11 is the top of the housing 1, and the side of the housing 1 opposite to the top is the bottom.

[0047] like Figure 2 , Figure 3 and Figure 7 As shown, a first support column 121 is provided on the base plate 12, and the heat sink 10 is supported on the first support column 121. The first support column 121 can provide support for the heat sink 10, thereby improving the installation stability of the heat sink 10, and can also support and limit the modularized circuit board 2, mounting base 3, display module 4 and heat sink 10 as a whole, thereby improving the installation stability of the entire module.

[0048] like Figure 2 and Figure 8 As shown, a second support column 122 is provided on the bottom plate 12, and a first step 121a is provided on the side of the top of the second support column 122; a support hole 221 is provided on the second circuit board 22 corresponding to the second support column 122, and the second support column 122 is inserted into the support hole 221, and the second circuit board 22 is supported on the first step 121a. This solution can provide effective positioning and support for the second circuit board 22 through the cooperation between the second support column 122 and the support hole 221, and the second circuit board 22 is supported on the first step 121a, thereby improving the installation stability of the second circuit board 22 and the overall module of the circuit board 2, the mounting base 3, the display module 4 and the heat sink 10. The first step 121a can be formed by setting a rib with a height lower than the second support column 122 on the side of the second support column 122.

[0049] like Figure 2 , Figure 3 , Figure 4 and Fig. 9As shown, the housing 1 further includes a side plate 13, on which a locking portion 131 is provided, and a locking groove 131a is provided on the locking portion 131; the side plate 13 is mounted on one end of the housing 1 and the locking portion 131 penetrates into the housing 1; the edge of the second circuit board 22 is locked in the locking groove 131a.

[0050] like Figure 2 and Figure 4 As shown, the first circuit board 21 and the second circuit board 22 are both provided with a first row of pin plugs 6 on their mutually facing surfaces.
