Description

Technical Field

[0001] The present invention relates to the technical field of heavy truck battery swap stations, and in particular to an electric heavy truck battery swap station. Background Art

[0002] In recent years, the new energy vehicle industry has developed rapidly, and electric vehicles have rapidly developed into the field of heavy-duty trucks. Heavy-duty trucks require larger battery packs than conventional battery packs due to their heavy weight and large load. The battery packs of electric heavy trucks are often installed behind their cabs. Due to their large storage capacity, conventional charging takes a long time to fully charge. In order to improve the transportation efficiency of electric heavy trucks, battery swap stations are often used to replace the battery packs of electric heavy trucks.

[0003] Due to the special transportation conditions of trucks, they often drive on the road for a long time. Long-term outdoor driving will affect the truck shell. In addition, various factors will cause damage to the battery pack. Damage to the battery pack may cause dangerous situations such as explosion during charging. The battery swap station itself does not have the function of detecting the battery pack. Summary of the invention

[0004] The object of the present invention is to provide an electric heavy truck battery swap station to solve the problems raised in the above-mentioned background technology.

[0005] In order to solve the above-mentioned technical problems, the present invention provides the following technical solutions: an electric heavy-duty truck battery swap station includes an outer shell, a transverse track, a transport module, a bridge, a sliding platform, a charging seat, and a detection and cleaning mechanism.

[0006] The battery swap station is used to replace the battery packs of heavy-duty electric trucks. The truck is driven to the designated workstation, and the original battery pack on the truck is removed by the handling module. The handling module moves the original battery pack along the transverse track to the side of the inspection and cleaning mechanism, which receives the original battery pack and inspects whether there is any obvious damage to the outside of the original battery pack and whether the outer shell is obviously deformed. When deformation damage occurs, the inspection and cleaning mechanism transports the original battery pack out of the outer shell to avoid charging hazards. When the battery is not damaged, the inspection and cleaning mechanism returns the original battery pack to its original position, the sliding table pops up, and the handling module moves the original battery pack to an idle sliding table, where the charging seat charges the original battery pack. The handling module moves the new battery pack that has been fully charged in advance to the truck for replacement.

[0007] Furthermore, the detection and cleaning mechanism includes a box body, a side wall mechanism, a chassis mechanism, and a flaw detection and cleaning mechanism.

[0016] When the direction-changing mechanism controls the torque in the moving direction of the mobile platform, when the original battery is not damaged, the side transmission mechanism transmits the torque to the first tooth column, and the tooth surface meshing between the first tooth column and the double-headed tooth column drives the outer cylinder to rotate, and the outer cylinder transmits the torque to the transmission frame to drive the mobile platform; when the original battery is damaged, the push cylinder pushes the first tooth column, and the double-headed tooth column is pushed by the first tooth column, and the limit buckle breaks through the limit plate, so that the first tooth column no longer contacts the double-headed tooth column, and the double-headed tooth column meshes with the tooth surface of the second tooth column, and the second tooth column transmits the reverse torque to the outer cylinder, driving the mobile platform to slide in the opposite direction.

[0051] Working principle of the present invention: The battery swap station is used to replace the battery pack of a heavy-duty electric truck. The truck is driven to a designated workstation, and the original battery pack on the truck is removed by the transport module 3. The transport module 3 transports the original battery pack along the transverse track 2 to the side of the detection and cleaning mechanism 7. The detection and cleaning mechanism 7 receives the original battery pack and detects whether there is any obvious damage or deformation on the outside of the original battery pack. The acoustic wave flaw detection mechanism 749 is initially in the flaw detection mode, and the acoustic wave oscillator 7491 emits high-frequency vibrations. The shock wave diffuses outward along the arc surface of the arc block 7497 to the entire outer surface of the original battery pack. The shock wave that contacts the outer surface is reflected back and received by the acoustic wave oscillator 7491. When the original battery pack is damaged, the speed angle of the oscillation wave reflected at the damaged position will be different from that in the normal state, and the oscillation wave received by the acoustic wave oscillator 7491 will be different. When the original battery pack is intact, the sonic oscillator 7491 switches to the cleaning mode, and the sonic oscillator 7491 sends an electrical signal to the fourth servo motor 7492. The fourth servo motor 7492 drives the back cylinder 7494 to rotate through the gear mechanism 7493, and the first hinge seat 7495 slides along the inclined groove 74941. Through the hinge relationship between the first hinge seat 7495, the second hinge rod 7496, and the arc block 7497, the arc block 7497 rotates around the sliding rod 7498, and the shock wave emitted by the sonic oscillator 7491 is gathered and emitted along the arc surface of the arc block 7497. The high-frequency gathered shock wave can clean the surface of the original battery pack. The sonic oscillator 7491 sends an electrical signal to the transport module 3 to transport the cleaned original battery pack to the charging seat 6; the transport module 3 transports the new battery pack that is fully charged in advance to the truck for replacement.
