[0030] 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.

[0031] The utility model embodiment provides a mobile power supply, such as Figures 1 to 5 As shown, the mobile power supply includes a shell 1, a support rod 2 and a mounting seat 3; a receiving chamber 11 for receiving the support rod 2 and the mounting seat 3 is opened on the shell 1, the support rod 2 and the mounting seat 3 are received in the receiving chamber 11, and the mounting seat 3 is fixed in the receiving chamber 11; the support rod 2 includes a mounting end 21, and the mounting end 21 is rotatably mounted on the mounting seat 3; the support rod 2 can be rotatably accommodated in the receiving chamber 11, and can be rotated out of the receiving chamber 11 to support the mobile power supply.

[0032] The mobile power supply of the utility model is provided with a mounting base 3, which is mounted in the accommodating cavity 11 of the housing 1, and the support rod 2 is rotatably mounted on the mounting base 3, so that it can be rotatably accommodated in the accommodating cavity 11 and rotated out of the accommodating cavity 11. Compared with the housing 1 of the mobile power supply, the mounting base 3 provides a mounting structure with stronger structural strength and more reliable for the rotatable mounting of the support rod 2, so that the overall mounting structure of the support rod 2 is sufficiently firm and reliable, the connection is not easily damaged, and the service life is long.

[0033] Specifically, when in use, the support rod 2 is rotated out of the accommodating cavity 11, and the support rod 2 is supported on the placement surface as a supporting component, so that the mobile power supply is in an inclined upright state, and the charging object, such as a mobile phone, can be magnetically attached to the mobile power supply for use, or an additional support arm for supporting the mobile phone is provided on the housing 1, so that the user can use the mobile power supply as a mobile phone holder, and can also support the mobile phone while charging. When the support rod 2 is not in use, it is directly rotated and stored in the accommodating cavity 11.

[0034] like Figure 2 , Figure 3 and Figure 5 As shown, the mounting seat 3 includes a first mounting portion 31, an assembly opening 111 is provided in the accommodating cavity 11, the first mounting portion 31 is assembled in the assembly opening 111, and the mounting end 21 is rotatably mounted on the first mounting portion 31. By providing the assembly opening 111 in the accommodating cavity 11 and assembling the first mounting portion 31 of the mounting seat 3 in the assembly opening 111, the mounting seat 3 can be partially embedded in the interior of the housing 1, making full use of the space, and making the installation of the mounting seat 3 more compact and reasonable.

[0035] Furthermore, if Figures 3 to 5As shown, the mobile power supply also includes a spring piece 4, which is installed in the housing 1. The spring piece 4 includes an elastic arm 41, which extends to the first mounting portion 31 and is arranged corresponding to the mounting end 21; wherein, when the support rod 2 is rotated out of the accommodating chamber 11, the elastic arm 41 interferes with the mounting end 21 to position the support rod 2. The spring piece 4 can position the rotated support rod 2 by the elastic force of its elastic arm 41, so that the support rod 2 is not easy to rotate when opened for use. Specifically, when the support rod 2 is rotated out of the accommodating chamber 11, due to the interference and abutment between the mounting end 21 and the elastic arm 41, the elastic arm 41 is deformed to generate damping, thereby positioning the support rod 2.

[0036] like Figures 4 to 5 As shown, the first mounting portion 31 includes two mounting side edges 311 arranged opposite to each other, and a mounting boss 211 is arranged on the mounting end 21, and the mounting boss 211 is embedded between the two mounting side edges 311 and rotatably mounted on the two mounting side edges 311. The mounting boss 211 is arranged on the mounting end 21 to facilitate the rotational connection of the mounting end 21. The mounting boss 211 can be mounted on the two mounting side edges 311 through the pin 5. Specifically, the two mounting side edges 311 are provided with mounting through holes 311b, and the mounting boss 211 is installed between the two mounting side edges 311 through the pin 5, which sequentially penetrates the mounting through holes 311b and the mounting boss 211. On the inner edge of the assembly opening 111, a blocking protrusion 12 is arranged at the position of the mounting through holes 311b of the two mounting side edges 311. During assembly, the support rod 2 can be mounted on the two mounting side edges 311 through the pin 5, and then the first mounting portion 31 is assembled into the assembly opening 111. At this time, the blocking protrusion 12 corresponds to the corresponding mounting through hole 311b, and the blocking protrusion 12 can play a role in blocking the pin shaft 5 to prevent the pin shaft 5 from escaping from the mounting through hole 311b.

[0037] like Figure 4 and Figure 6 As shown, the mounting boss 211 is provided with a supporting boss 211a corresponding to the elastic arm 41. When the support rod 2 is rotated out of the accommodating cavity 11, the supporting boss 211a interferes with the elastic arm 41 to position the support rod 2. The supporting boss 211a can easily interfere with the elastic arm 41 to improve the positioning of the support rod 2.

[0038] Specifically, Figure 4 and Figure 6As shown, the elastic arm 41 includes a first connecting section 411, a second connecting section 412 and a third connecting section 413. The first connecting section 411 and the second connecting section 412 are bent and connected to form a receiving space 414 facing the mounting boss 211, and the third connecting section 413 is connected to the second connecting section 412. When the support rod 2 is received in the receiving chamber 11, the abutting boss 211a is located in the receiving space 414; when the support rod 2 is rotated out of the receiving chamber 11, the abutting boss 211a is rotated out of the receiving space 414 and interferes with the third connecting section 413. The receiving space 414 formed by the first connecting section 411 and the second connecting section 412 is used to avoid the abutting boss 211a from continuing to abut against the elastic arm 41 after the support rod 2 is received, so as to prevent the elastic arm 41 from fatigue and loss of elasticity. When the elastic arm 41 positions the support rod 2, the third connecting section 413 is used to interfere and abut. More specifically, the elastic sheet 4 further includes a third mounting portion 42 , the third mounting portion 42 is mounted on the inner surface of the housing 1 , and the first connecting section 411 is connected to the third mounting portion 42 .

[0039] like Figure 5 and Figure 7 As shown, two mounting side edges 311 are provided with avoidance grooves 311a corresponding to the mounting ends 21. When the support rod 2 is rotated out of the accommodating cavity 11, the mounting ends 21 are rotated into the avoidance grooves 311a to prevent the first mounting portion 31 from hindering the rotation of the support rod 2 when the support rod 2 is opened. A locking boss 312 is provided on the side of the first mounting portion 31. The locking boss 312 is located in the housing 1 and can interfere with the assembly opening 111. When an external force pulls the first mounting portion 31, the locking boss 312 can interfere with the assembly opening 111. The locking boss 312 can play a limiting role to prevent the first mounting portion 31 from escaping from the assembly opening 111, thereby improving the overall installation firmness of the mounting seat 3. The mounting seat 3 also includes a second mounting portion 32, the first mounting portion 31 is connected to the second mounting portion 32, and the locking boss 312 is arranged on a side of the first mounting portion 31 away from the second mounting portion 32. Specifically, when assembling the mounting seat 3 , the first mounting portion 31 is first assembled into the assembly opening 111 .

[0040] like Figures 3 to 5 As shown, the elastic arm 41 is connected to the third mounting portion 42, specifically, the first connecting section 411 is connected to the third mounting portion 42. The mobile power supply also includes a fastener 6, which passes through the housing 1 and connects and fixes the second mounting portion 32 and the third mounting portion 42. This solution fixes the spring 4 and the mounting seat 3 at the same time by the fastener 6, and has a simple structure and is easy to assemble. Specifically, the fastener 6 is a screw, which passes through the third mounting portion 42 of the spring 4 and the housing 1 in turn, and is threadedly connected to the second mounting portion 32. Two fasteners 6 are provided to improve the fixation of the spring 4 and the mounting seat 3.

[0041] like Figure 3 and Figure 7 As shown, a first interlocking cavity 112 is provided in the accommodating cavity 11, and a first interlocking boss 321 is provided on the side of the second mounting portion 32 facing the accommodating cavity 11, and the first interlocking boss 321 is interlocked in the first interlocking cavity 112, so as to improve the assembly convenience and installation firmness of the mounting seat 3. The fastener 6 can pass through the first interlocking cavity 112 and then be connected to the first interlocking boss 321. Furthermore, on the second mounting portion 32, a first interlocking groove 322 is provided between the first interlocking boss 321 and the first mounting portion 31; in the accommodating cavity 11, a second interlocking boss 113 is provided between the first interlocking cavity 112 and the assembly opening 111, so as to further improve the assembly convenience and installation firmness of the mounting seat 3.

[0042] like Figure 4 and Figure 5 As shown, a slot 421 is provided on one side of the third mounting portion 42 away from the elastic arm 41, and a post 13 is provided on the inner surface of the housing 1, and the post 13 is stuck in the slot 421. The cooperation between the slot 421 and the post 13 can play a pre-positioning role when installing the spring sheet 4, and at the same time improve the firmness of the installation of the spring sheet 4. Specifically, two slots 421 and two posts 13 are provided correspondingly.

[0043] It should be understood that the above embodiments are only used to illustrate the technical solutions of the present utility model rather than to limit it.
