Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0030] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0031] Example 1:

[0032] like Figure 1-5 As shown, a portable mobile PD power supply includes multiple power supply units 1.

[0033] The two adjacent power supply units 1 are connected by a connecting member 2, which includes a connecting shaft 9 and a limit assembly 12. The power supply unit 1 includes a shell 3, a connecting ear 1 4 integrally formed on one side of the shell 3, and a connecting ear 2 5 integrally formed on the other side of the shell 3. The connecting shaft 9 is rotatably connected to the inner wall of one group of connecting ears 1 4 and connecting ears 2 5, and the limit assembly 12 is movably arranged on the inner side of the other group of connecting ears 1 4 and connecting ears 2 5.

[0034] Multiple power supply units 1 are movably connected by connectors 2. When in use, if the storage space cannot accommodate the "I"-shaped power supply unit 1, the user can flexibly adjust the angle or position of the power supply unit 1 according to their own needs and the size of the storage space so that it can be folded.

[0035] This device is provided with multiple power supply units 1 to meet the user's charging function. The user can use the connecting piece 2 to rotate and fold the power supply unit 1, thereby changing the shape of the power supply unit 1 so that it can be flexibly adjusted according to the user's needs and storage space, thereby improving the portability of the device.

[0036] In this embodiment, a battery compartment 11 is provided inside the power supply unit 1 , and a compartment door 8 is fixed to the side wall of the power supply unit 1 by bolts.

[0037] The battery compartment 11 has a built-in PD battery cell 14 , and an electrode 1 10 and an electrode 2 13 are fixedly connected to the inner wall of the battery compartment 11 , and both the electrode 1 10 and the electrode 2 13 are electrically connected to the PD battery cell 14 .

[0038] Two adjacent PD cells 14 are connected by a wire 7 , and the wire 7 is electrically connected to electrode 1 10 and electrode 2 13 . A terminal 6 is fixedly connected to a side wall of the housing 3 at the end, and the terminal 6 is electrically connected to the wire 7 .

[0039] Example 2:

[0040] A portable mobile PD power supply. This embodiment makes the following improvements based on the first embodiment: Figure 1-5 As shown:

[0041] The limiting assembly 12 includes a sliding rod 15 and a tooth 16 and a tooth 2 17 integrally formed on the outer wall of the sliding rod 15. The sliding rod 15 is slidably connected to the inner walls of the connecting ear 1 4 and the connecting ear 2 5, and the inner walls of the connecting ear 2 5 and the connecting ear 1 4 are respectively provided with a tooth groove 19 and a tooth groove 2 21 that cooperate with the tooth 1 16 and the tooth 2 17 to limit the position.

[0042] The inner walls of the connecting ear 2 5 and the connecting ear 1 4 are also respectively provided with a make way groove 1 20 and a make way groove 22 which are interconnected with the tooth groove 1 19 and the tooth groove 2 21. The end of the sliding rod 15 is buckled with a spring 18, and the other end of the spring 18 is buckled with the inner wall of the connecting ear 1 4.

[0043] In this embodiment: when the user needs to adjust the angular position of the power supply unit 1, the slide bar 15 is pressed to compress the spring 18, thereby driving the tooth 16 and the tooth 2 17 to leave the tooth groove 19 and the tooth groove 2 21. At this time, the tooth 16 and the tooth 2 17 are respectively located in the make way groove 1 20 and the make way groove 2 22, and the connecting ear 1 4 and the connecting ear 2 5 are no longer restricted and can be rotated at will. After the adjustment is completed, the slide bar 15 is released, and the spring 18 uses its own elasticity to push the tooth 16 and the tooth 2 17 to reset, thereby fixing the connecting ear 1 4 and the connecting ear 2 5.

[0044] In this invention, tooth 16, tooth 2 17, tooth groove 19 and tooth groove 2 21 are provided, and tooth groove 19 and tooth groove 2 21 are used to limit tooth 16 and tooth 2 17, so that connecting ear 1 4 and connecting ear 2 5 cannot rotate relative to each other, thereby achieving limited fixation of the two power supply units 1 and increasing the stability of the device.

[0045] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various modifications or substitutions within the technical scope disclosed in the present invention, and such modifications or substitutions are intended to be within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope of protection of the claims.
