[0002] A battery box, also known as a battery tray or battery pack lower housing, is a shell or container structure used to house a battery pack. Its main function is to house the battery pack. With the development of society, two-wheeled electric vehicles have become an important tool for the daily travel of hundreds of millions of people. For some users, there is a great demand for range, which has led to the emergence of the "battery swapping" mode for electric vehicles. The "battery swapping" mode places high demands on the convenience of battery replacement.

[0003] Currently, battery boxes are generally fixed to the bottom of the vehicle seat with bolts or straps. In daily use, the battery box is inconvenient to disassemble and cannot be quickly replaced. Furthermore, after prolonged use, the battery box is prone to loosening, which may lead to power outages or other dangerous situations, and it cannot effectively absorb shocks. Utility Model Content

A limit block 1206 is slidably connected through the fixing block 11 to the outer wall of the fixing rod 1203. The bottom of 6 is fixedly connected to the top of the fixing plate 8. By pushing the push block 1204 set in the fixing component 12, the fixing rod 1203 is driven to slide in the inner cavity of the fixing sleeve 1201, away from the limiting block 1206 and the fixing block 11, the fixing plate 8 can be rotated on the inner wall of the connecting seat 6 through the connecting post 7. At this time, the abutting block 9 fixedly connected to the bottom side of the fixing plate 8 no longer abuts the battery box body 2. The battery box body 2 can be easily taken out or replaced by the handle set on the battery box body 2. The disassembly and installation of the battery box body 2 is more convenient. After the replacement is completed, the fixing plate 8 is rotated and the push block 1204 is released. Under the force of the return spring 1202, the fixing rod 1203 passes through the fixing block 11 and the limiting block 1206 to complete the fixation of the battery box body 2.

[0027] refer to Figure 1 and Figure 3 As shown, a shock-absorbing strip 3 is movably connected to the bottom of the battery box body 2. The bottom of the shock-absorbing strip 3 is fixedly connected to the bottom of the inner cavity of the box base 1. The shock-absorbing strip 3 can absorb the force of bumps generated by complex road surfaces and play a role in shock absorption for the battery box body 2. Multiple heat dissipation holes 4 are opened on the front and back of the inner cavity of the box base 1, and the other end of the heat dissipation hole 4 is opened on the top of the box base 1.

[0028] refer to Figure 2 and Figure 5As shown, a sealing plate 13 is installed on the inner wall of the mounting groove 5 via a hinge. A pressing assembly 14 is provided at the bottom of the sealing plate 13. The pressing assembly 14 includes four fixing sleeves 1401 fixed to the bottom of the sealing plate 13. A pressing spring 1402 is fixedly connected to the top of the inner cavity of the fixing sleeve 1401. A connecting post 1403 is fixedly connected to the other end of the pressing spring 1402. A pressing block 1404 is fixedly installed at the bottom of the connecting post 1403. The bottom of the pressing block 1404 abuts against the top four corners of the battery box body 2. The pressing blocks 1404 provided by the four pressing assemblies 14 will abut against the top four corners of the battery box body 2, and the battery box body 2 will be pressed and fixed under the action of the pressing spring 1402.

[0029] refer to Figure 2 and Figure 5 As shown, a limiting component 15 is provided on one side of the sealing plate 13. The limiting component 15 includes a limiting plate 1501 fixedly connected to one side of the sealing plate 13. A sliding cavity 1502 is formed inside the limiting plate 1501. Limiting posts 1503 are slidably connected to both sides of the inner cavity of the sliding cavity 1502. A second return spring 1504 is fixedly connected to one end of the two limiting posts 1503 facing each other. A slider 1505 is fixedly connected to the outer wall of the limiting post 1503. A second sliding groove 1506 that matches the slider 1505 is formed on the top of the limiting plate 1501. The top of the slider 1505 is fixedly connected to the second sliding groove 1506. The base 1 is fixedly connected with push block 2 1507. The top of the base 1 is provided with a limiting groove 16 that matches the limiting plate 1501.

One end of the two limiting posts 1503 will disengage from the inner cavity of the limiting hole 17, and the sealing plate 13 can be opened. Conversely, by releasing the push block 2 1507, the limiting post 1503 will return to the limiting hole 17 under the force of the reset spring 2 1504 to complete the limiting of the sealing plate 13.

[0030] Working principle: When replacing or removing the housing 1, by pushing the two push blocks 1507 of the limiting component 15 inward, the slider 1505 and the limiting post 1503 fixedly connected to the bottom slide inside the sliding cavity 1502. One end of the two limiting posts 1503 will disengage from the inner cavity of the limiting hole 17, at which point the sealing plate 13 can be opened. Conversely, by releasing the push blocks 1507, the limiting post 1503 returns to the limiting hole 17 under the force of the return spring 1504, thus limiting the sealing plate 13. Then, by pushing the push block 1204 of the fixing component 12, the fixing rod 1203 slides in the inner cavity of the fixing sleeve 1201, moving away from the limiting block 1206 and the fixing block 11, the fixing plate 8 can rotate on the inner wall of the connecting seat 6 via the connecting post 7. At this time, the abutment block 9 fixedly connected to the bottom side of the fixing plate 8 does not... The battery box body 2 can be easily removed or replaced using the handle on it, making disassembly and installation more convenient. After replacement, the fixing plate 8 is rotated to release the push block 1204. Under the force of the return spring 1202, the fixing rod 1203 passes through the fixing block 11 and the limiting block 1206 to fix the battery box body 2. At the same time, after replacing the battery box body 2, the sealing plate 13 is limited and closed by the limiting component 15. The pressing blocks 1404 set by the four pressing components 14 at the bottom of the sealing plate 13 will abut against the four corners of the top of the battery box body 2. Under the action of the pressing spring 1402, the battery box body 2 is pressed and fixed. The shock-absorbing strip 3, which is fixedly connected to the bottom of the inner cavity of the box base 1, can absorb the force of bumps generated by complex road surfaces and play a role in shock absorption for the battery box body 2.
