[0033] See also Figure 1-3 As shown, this embodiment is a mobile phone lithium battery that is easy to connect and disassemble, including:

[0034] The lithium battery assembly 1 includes a plastic shell 13;

[0035] The movable assembly 2 includes a support block 21 placed at one side of the plastic shell 13, a conductive contact 22 fixedly connected to the outer surface of the support block 21, a fixed block 23 fixedly connected to the upper end of the support block 21, a first telescopic spring 24 fixedly connected to the inner position of the fixed block 23, a movable block 25 fixedly connected to the top position of the first telescopic spring 24, a movable column 26 fixedly connected to both ends of the inner side of the support block 21, a second telescopic spring 27 fixedly connected to the inner side of the movable column 26, a fixed column 28 fixedly connected to the outer end of the second telescopic spring 27, and a support plate 29 fixedly connected to the outer end of the fixed column 28;

[0036] The support block 21 is used to fix the conductive contact 22, the conductive contact 22 is used to be electrically connected to the battery core 11, the fixed block 23 is used to limit the movable block 25, the movable block 25 is used to limit the support block 21, the first telescopic spring 24 is used to support the movable block 25, the fixed column 28 is used to guide the movable column 26, the movable column 26 is used to drive the support block 21 to move, the support plate 29 is used to support the fixed column 28, and the second telescopic spring 27 is used to support the movable column 26;

[0037] The lithium battery assembly 1 further includes a battery core 11 and a protective shell 12 fixedly connected to the outer surface of the battery core 11, and a plastic shell 13 fixedly connected to both ends of the protective shell 12;

[0038] The battery core 11 is used to store electric energy, the protective shell 12 is used to protect the outer surface of the battery core 11, and the plastic shell 13 is used to protect both ends of the battery core 11;

[0039] The fixed block 23 has a hollow structure inside that is opened relative to the movable block 25, and the movable block 25 is located at an upper end of one side inside the plastic shell 13;

[0040] The movable block 25 can move inside the fixed block 23. When the movable block 25 moves downward, it drives the first telescopic spring 24 to be compressed.

[0041] The support block 21 is a U-shaped structure, and the conductive contact 22 is electrically connected to the battery core 11 through a circuit;

[0042] When the support block 21 moves, the conductive contact 22 is driven to move, and the conductive contact 22 is always electrically connected to the battery cell 11 through the circuit;

[0043] The support plate 29 is fixedly connected to the two sides of the outer end of the plastic shell 13, and the interior of the fixed column 28 has a hollow structure opened relative to the movable column 26;

[0044] The support plates 29 in the fixed column 28 are fixed at two sides of the plastic shell 13, and the movable column 26 can move in the fixed column 28;

[0045] Working principle: When the lithium battery assembly 1 needs to be checked for power connection, the movable block 25 is pressed downward, and the movable block 25 moves downward in the fixed block 23, and drives the first telescopic spring 24 to be compressed. When the movable block 25 moves to the inside of the fixed block 23, the movable block 25 and the plastic shell 13 are not in contact. At this time, under the elastic force of the second telescopic spring 27, the second telescopic spring 27 applies an outward thrust to the movable column 26, so that the movable column 26 and the support block 21 move outward. The outward movement of the support block 21 drives the conductive contact 22 to move outward, so that the conductive contact 22 can be exposed outward.

[0046] When the vehicle inspection is completed, the movable block 25 continues to be pressed downward so that the plastic shell 13 does not block the movable block 25, and an inward force is applied to the support block 21. The support block 21 drives the conductive contact 22 to move inward, and drives the movable column 26 to move inward. The movable column 26 drives the second telescopic spring 27 inward to be compressed. When the support block 21 moves to be flush with the outer end of the plastic shell 13, the movable block 25 moves upward under the elastic force of the first telescopic spring 24, and the plastic shell 13 blocks the movable block 25, thereby limiting the support block 21. Example

[0047] See also Figure 4 As shown, this embodiment is based on the above embodiment 1 and also includes:

[0048] The mounting assembly 3 is fixedly connected to the central position inside the plastic shell 13;

[0049] The mounting assembly 3 includes a third telescopic spring 31 fixedly connected to the central position of the plastic shell 13, a fixed plate 32 fixedly connected to the outer end of the third telescopic spring 31, a movable plate 33 placed at the central position of the plastic shell 13, a fixed shaft 34 rotatably connected to the inner position of the front end of the movable plate 33, and a limit plate 35 fixedly connected to the two ends of the fixed shaft 34;

[0050] The third telescopic spring 31 is used to support the fixed plate 32, the fixed plate 32 is used to contact the outer side of the movable plate 33, the movable plate 33 is used to take out the lithium battery assembly 1, the fixed shaft 34 allows the movable plate 33 to rotate, and the limit plate 35 is used to contact the mobile phone shell;

[0051] The limiting plate 35 penetrates through the plastic shell 13 and extends outward, and the movable plate 33 is an L-shaped structure;

[0052] When the movable plate 33 rotates along the fixed shaft 34, the movable plate 33 is in an inverted L shape;

[0053] Working principle: when the lithium battery assembly 1 needs to be installed inside the mobile phone case, the fixed plate 32 is moved inward, and the fixed plate 32 moves inward to compress the third telescopic spring 31, and the movable plate 33 is rotated to make the movable plate 33 rotate to be flush with the limit plate 35. At this time, the lithium battery assembly 1 is placed inside the mobile phone case, and the force applied to the fixed plate 32 is released. Since the third telescopic spring 31 is compressed to generate elastic force, an outward force is applied to the fixed plate 32. The fixed plate 32 moves outward to drive the movable plate 33 and the limit plate 35 to move outward, so that the limit plate 35 extends outward and extends into the groove inside the mobile phone case, and the installation of the lithium battery assembly 1 can be completed;

[0054] When the lithium battery assembly 1 needs to be taken out from the inside of the mobile phone case, the fixed plate 32 is moved inwardly, so that the fixed plate 32 moves inwardly. Since the fixed plate 32 does not block the movable plate 33, the movable plate 33 is moved inwardly again, so that the movable plate 33 drives the limiting plate 35 to move inwardly, and the movable plate 33 is rotated so that the movable plate 33 is perpendicular to the limiting plate 35. At this time, since the movable plate 33 is in an inverted L shape and the limiting plate 35 does not contact the mobile phone case, the lithium battery assembly 1 can be taken out from the inside of the mobile phone case by pulling the movable plate 33 upwards.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0056] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
