Description

Technical Field

[0001] The utility model relates to the technical field of new energy vehicles, in particular to a new energy vehicle component structure. Background Art

[0002] In Chinese patent CN110395101B, although the roll-formed frame beam (frame) of the battery pack shell is one-piece, it does not use ultra-high-strength steel (if ultra-high-strength steel is used, a single roll-forming process will also be difficult to produce an integrated frame beam), which is not conducive to the lightweight of the battery pack shell. At the same time, the structure of the frame beam (frame) and the bottom of the battery pack shell can only be connected by a gluing (adhesive) process, but the gluing process has low strength and is prone to aging and fatigue. Therefore, this connection method between the frame beam (frame) and the bottom of the battery pack shell is less safe, not conducive to mass production, and has a high cost. Moreover, it is difficult to disassemble and assemble the shell after gluing, which makes it inconvenient to inspect its internal structure. In view of this, a new energy vehicle component structure is proposed. Utility Model Content

[0026] See also Figure 1-4 The utility model provides a new technical solution: a new type of new energy vehicle component structure, including a new energy battery lower protective shell 1, a new energy battery upper protective shell 2 is arranged on the upper surface of the new energy battery lower protective shell 1, and six hollow columns 3 are symmetrically installed on the lower surface of the new energy battery upper protective shell 2;

[0027] The disassembly and assembly mechanism is arranged on the upper protective shell 2 of the new energy battery, and the disassembly and assembly mechanism is used for disassembling the battery protective shell for inspection and maintenance. The disassembly and assembly mechanism includes six springs 4, and the six springs 4 are respectively fixedly installed in the inner walls of the six hollow columns 3;

[0028] The heat dissipation and cooling mechanism is arranged on the lower protective shell 1 of the new energy battery. The heat dissipation and cooling mechanism is used to cool the battery in the battery protective shell. The heat dissipation and cooling mechanism includes four semiconductor cooling plates 13. The four semiconductor cooling plates 13 are symmetrically installed on the inner walls on the opposite sides of the lower protective shell 1 of the new energy battery.

[0029] Furthermore, the disassembly and assembly mechanism also includes six circular rings 5 ​​and six fixed rods 6. The six circular rings 5 ​​are respectively fixedly mounted on the lower ends of the six springs 4. The six fixed rods 6 are fixedly sleeved in the inner walls of the six circular rings 5, and the six fixed rods 6 are slidably sleeved in the inner wall of the hollow column 3.

[0030] Furthermore, the disassembly and assembly mechanism also includes six pull rings 8 and twelve grooves 7. The six pull rings 8 are fixedly installed on the upper surfaces of the six fixed rods 6, and the twelve grooves 7 are symmetrically opened on the outer surfaces of the six fixed rods 6.

[0031] Furthermore, the disassembly and assembly mechanism also includes twelve round holes 9 and twelve round balls 10 . The twelve round holes 9 are symmetrically arranged on the outer surfaces of the six hollow columns 3 , and the twelve round balls 10 are respectively arranged in the twelve round holes 9 .

[0032] Furthermore, the disassembly and assembly mechanism also includes six slots 11 and twelve latch holes 12 . The six slots 11 are symmetrically arranged on both sides of the lower protective shell 1 of the new energy battery, and the twelve latch holes 12 are symmetrically arranged in the inner walls of the six slots 11 .

[0033] Furthermore, the heat dissipation and cooling mechanism also includes four cooling fins 14 and four cooling fans 15 . The four cooling fins 14 are respectively fixedly mounted on opposite surfaces of the four semiconductor refrigeration fins 13 , and the four cooling fans 15 are respectively fixedly mounted on opposite surfaces of the four cooling fins 14 .

[0034] Furthermore, the heat dissipation and cooling mechanism also includes four heat dissipation fans 16, which are respectively fixedly installed on the opposite surfaces of the four semiconductor refrigeration plates 13. When the new type of new energy vehicle component structure is used, the pull ring 8 is pulled, and the pull ring 8 drives the fixed stick 6 fixedly installed on the lower surface to move upward, and the fixed stick 6 drives the circular ring 5 fixedly sleeved on the outer surface to move upward. While the circular ring 5 moves upward, it applies pressure to the spring 4 fixedly installed on the upper surface to shrink it. At the same time, the groove 7 provided on the outer surface of the fixed stick 6 is aligned with the circular hole 9. At this time, the fixed stick 6 no longer applies pressure to the round ball 10, and the round ball 10 shrinks into the hollow column 3. At this time, the hollow column 3 is inserted into the slot 11, and no tension is applied to the pull ring 8. At the same time, the spring 4 is no longer under force, and the spring 4 expands. The spring 4 applies a downward thrust to the circular ring 5 fixedly installed at the lower end to move it downward. At the same time, the fixed stick 6 hits the round ball 10 to make it protrude from the hollow column 3. And it is snapped into the snap hole 12 for fixation. At this time, the installation is completed. When it needs to be disassembled, fully pull the pull ring 8 to contact the snap-in fixation and disassemble it. When the battery inside the protective shell needs to be cooled, the semiconductor refrigeration plate 13 is used for cooling, and the cold air is transmitted to the protective shell through the cooling plate 14 and the cooling fan 15, and the heat of the semiconductor refrigeration plate 13 itself will be discharged through the cooling fan 16. The new energy vehicle component structure can connect the new energy battery lower protective shell 1 and the new energy battery upper protective shell 2 by snapping for fixation, and it is convenient to disassemble and assemble without the aid of tools. The new energy battery inside the protective shell can be quickly disassembled and assembled for inspection and maintenance, which is more convenient. In addition, the new energy vehicle component structure is cooled by the semiconductor refrigeration plate 13, and the cold air is transmitted to the protective shell to cool the new energy battery in the protective shell, maintain its suitable working temperature, and prevent accidents.

[0035] Working principle: When the new type of new energy automobile component structure is used, the pull ring 8 is pulled, and the pull ring 8 drives the fixed stick 6 fixed on the lower surface to move upward, and the fixed stick 6 drives the circular ring 5 fixed on the outer surface to move upward. While the circular ring 5 moves upward, it applies pressure to the spring 4 fixed on the upper surface to shrink. At the same time, the groove 7 on the outer surface of the fixed stick 6 is aligned with the circular hole 9. At this time, the fixed stick 6 no longer applies pressure to the round ball 10, and the round ball 10 shrinks into the hollow column 3. At this time, the hollow column 3 is inserted into the slot 11. At this time, no tension is applied to the pull ring 8, and the spring 4 is no longer under pressure. The force causes the spring 4 to expand. The spring 4 applies a downward thrust to the circular ring 5 fixed at the lower end, causing it to move downward. At the same time, the fixing rod 6 hits the round ball 10, causing it to protrude from the hollow column 3 and be snapped into the snap hole 12 for fixation. At this time, the installation is completed. When it needs to be disassembled, the pull ring 8 is fully pulled to contact the snap-fit ​​fixation for disassembly. When it is necessary to cool the battery inside the protective shell, the semiconductor refrigeration sheet 13 is used for cooling, and the cold air is transmitted to the protective shell through the cooling sheet 14 and the cooling fan 15, and the heat of the semiconductor refrigeration sheet 13 itself is discharged through the cooling fan 16.
