DETAILED DESCRIPTION

[0025] The present invention can be further understood through the specific embodiments given below, but they are not intended to limit the present invention.

[0026] Embodiment 1: A charging module, comprising: a battery cell 4, a module housing 1 for placing the battery cell 4, and an input interface 16, an output interface 17 and a signal interface 18 are arranged on the outer wall of the module housing 1, a cover plate 14 is arranged above the module housing 1, and a clamping plate 3 is respectively arranged at the front and rear ends of the module housing 1;

[0028] The battery cell is placed inside the module housing. The pressure of the battery cell can cause the pressing plate to rotate, so that the two ends of the battery cell are gradually pressed between the first clamping plates of the clamping plate, and the second clamping plate of the clamping plate gradually enters the bottom groove. At this time, the torsion spring will be deformed and stressed.

[0029] A first fixing hole 10 is formed on the top of the clamping plate 3, a second fixing hole 11 is formed on one end of the module housing 1 close to the clamping plate 3, and a through hole 13 is formed on the cover plate 14 corresponding to the first fixing hole 10 and the second fixing hole 11 respectively;

[0032] The clamping plate 3 comprises a first clamping plate 31 and a second clamping plate 32 . A cushion block 15 is disposed on a side of the second clamping plate 32 opposite to the first clamping plate 31 .

[0033] The depth of the bottom groove 2 is 1.5 times the height of the cushion block 15 .

[0034] A pad 9 is fixedly mounted on one side of the first clamping plate 31 relative to the battery core 4 .

[0035] The cover plate 14 is connected to the module housing 1 via a second screw 12 .

[0036] A torsion spring 6 is arranged between the connecting rod 5 and the fixing groove 7 .

[0037] A second screw 12 is disposed between the through hole 13 and the first fixing hole 10 , and between the second fixing hole 11 and the through hole 13 .

[0038] Embodiment 2: A charging module, comprising: a battery cell 4, a module housing 1 for placing the battery cell 4, and an input interface 16, an output interface 17 and a signal interface 18 are arranged on the outer wall of the module housing 1, a cover plate 14 is arranged above the module housing 1, and a clamping plate 3 is respectively arranged at the front and rear ends of the module housing 1;

[0039] A fixing groove 7 is respectively provided on both sides of the clamping plate 3 and on the module housing 1, and a connecting rod 5 rotatably connected to the fixing groove 7 is fixedly installed on the side wall of the clamping plate 3;

[0040] During the installation process, the battery cell is placed inside the module housing and between the two clamping plates, and the clamping plates are rotatably connected to the fixing grooves through connecting rods. By flipping the clamping plates, the operating space on both sides of the battery cell can be expanded, thereby facilitating the installation of the battery cell.

[0041] A first fixing hole 10 is formed on the top of the clamping plate 3, a second fixing hole 11 is formed on one end of the module housing 1 close to the clamping plate 3, and a through hole 13 is formed on the cover plate 14 corresponding to the first fixing hole 10 and the second fixing hole 11 respectively;

[0042] After the battery cell is placed, the clamping plate is pressed and rotated, so that the battery cell is clamped between the two clamping plates, and connected to the first fixing hole and the second fixing hole on the module shell through the through holes of the cover plate, thereby improving the convenience of personnel operation and helping to reduce the overall volume.

[0043] A bottom groove 2 is disposed on one side of the inner bottom wall of the module housing 1 close to the clamping plate 3 .

[0044] The clamping plate 3 comprises a first clamping plate 31 and a second clamping plate 32 . A cushion block 15 is disposed on a side of the second clamping plate 32 opposite to the first clamping plate 31 .

[0045] The depth of the bottom groove 2 is 3.5 times the height of the cushion block 15 .

[0050] The working principle is:

[0051] When in use, first place the battery cell inside the module shell. The pressure of the battery cell can make the pressing plate rotate so that the two ends of the battery cell are gradually pressed between the first clamping plate of the clamping plate, and the second clamping plate of the clamping plate gradually enters into the bottom groove. At this time, the torsion spring will be deformed and stressed. When the lower part of the clamping plate completely enters into the bottom groove, the pad inside the first clamping plate will fit with the two ends of the battery cell to fix the battery cell. The pad on the bottom wall of the second clamping plate fits with the bottom groove so that the surface of the second clamping plate is flush with the bottom wall inside the module shell. Then the cover plate is placed on the upper part of the module shell so that the first fixing hole and the second fixing hole correspond to the through hole. Then the cover plate is fixed by the second screw to fix the battery cell inside the module shell.

[0052] When the above-mentioned charging module is used, during the installation process, the battery cell is placed inside the module shell and between the two clamping plates, and the clamping plates are rotatably connected to the fixing grooves through connecting rods. By flipping the clamping plates, the operating space of personnel on both sides of the battery cell can be expanded, thereby facilitating the installation of the battery cell. After the battery cell is placed, the clamping plates are pressed and rotated, so that the battery cell is clamped between the two clamping plates, and is respectively connected to the first fixing hole and the second fixing hole on the module shell through the through holes of the cover plate, thereby improving the convenience of personnel operation and also helping to reduce the overall volume.
