Description

Technical Field

[0002] Electric vehicles refer to vehicles that use onboard power as power, use motors to drive wheels, and comply with various requirements of road traffic and safety regulations. As their impact on the environment is relatively small compared to traditional vehicles, their prospects are widely optimistic. Their working principle is mainly to drive the motor to rotate after the current in the battery is regulated by the power regulator, and then drive the car through the power transmission system. With the continuous development of electric vehicles, in order to solve the problem of difficult and slow charging, some electric vehicles will achieve continuous power output by directly replacing batteries, and a battery replacement framework is required in this process.

[0003] At present, the battery installation methods of the battery swap frame mainly include side-mounted and top-mounted. After the top-mounted battery is installed, it is difficult to replace the battery, and the upper equipment and battery need to be removed to remove the lower battery. The existing side-mounted type is mainly achieved by pushing the battery into the frame. First, when taking and placing the battery, the friction between the battery and the frame is large, which can easily damage the battery and the frame. In addition, during the pushing process, the battery may be offset, which is not convenient for battery fixation. The battery fixation is also cumbersome and the installation efficiency is low.

[0033] Reference Figure 1 , Figure 4 and Figure 5The air release unit includes a compression chamber 21 opened inside the transverse beam 4, a second spring 22 is fixedly connected to a side of the compression chamber 21 close to the guide fixing member 5, a piston 23 tightly fitted to the inner wall of the compression chamber 21 is fixedly connected to the end of the second spring 22, and a pressing block 24 slidably connected to the transverse beam 4 is fixedly connected to the side of the piston 23 away from the second spring 22, wherein the connecting pipe 1 is fixedly connected to the side of the transverse beam 4 away from the pressing block 24, and the connecting pipe 1 is connected to the compression chamber 21, and the output end of the elastic cylinder 15 is connected to the air pressure valve 20, and the air pressure valve 20 is connected to the end of the connecting pipe 1 away from the transverse beam 4. The specific structure of the air pressure valve 20 can refer to the technical solution in the prior art, and those skilled in the art can know it and will not be repeated here. When the air pressure valve 20 is subjected to a certain air pressure, it will be in an open state.

[0034] Reference Figure 2 The side walls of the battery pack 8 are symmetrically provided with mounting members 9 , the size of the mounting members 9 is smaller than the size of the guide groove 7 , and the size of the battery pack 8 matches the size between two adjacent groups of guide fixing members 5 .

[0035] The battery-swapping vehicle includes the battery-swapping framework mentioned above.

[0036] In the utility model, when taking and placing the battery pack 8, in the initial state, the limit plate 18 is received in the mounting groove 14 under the action of the elastic cylinder 15, and the mounting part 9 of the battery pack 8 is aligned with the guide groove 7 and pushed inward. During the pushing process, no friction is generated between the battery pack 8 and the device, and its main friction force comes from the mounting part 9 and the inner wall of the guide groove 7, which can effectively prevent the battery pack 8 from being damaged during the taking and placing process; when the mounting part 9 contacts the trapezoidal block 12, as the battery pack 8 is pushed, the mounting part 9 will press down the trapezoidal block 12, compress the compression cylinder 11, and the gas inside it will enter the elastic cylinder 15 through the pipeline, and drive the elastic cylinder 15 to extend outward, and at the same time drive the movable part 16 and the tooth plate 17 to move synchronously, and under the action of the gear 19, drive the limit plate 18 to the guide groove 7, the other side of the mounting member 9 can be blocked. It needs to be explained that at this time, although the limit plate 18 on the other side also rotates toward the guide groove 7, due to the obstruction of the mounting member 9 in the corresponding direction, the limit plate 18 will not be completely rotated to the guide groove 7. When the battery pack 8 is rotated between the two sets of limit plates 18, the limit plates 18 on both sides can fix the mounting member 9; when the battery pack 8 needs to be taken out, the pressing block 24 is pressed to discharge the gas in the compression chamber 21 to the air pressure valve 20 through the connecting pipe 1, so that the air pressure valve 20 is in an open state. At this time, the air pressure in the elastic cylinder 15 is discharged through the air pressure valve 20 and shrinks to the initial position at the same time, thereby driving the limit plate 18 to rotate to the mounting groove 14, and then the battery pack 8 can be taken out, and each battery pack 8 can be independently taken and placed.

[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
