Description

Technical Field

[0001] The present application relates to the technical field of chassis layout design for quick-change electric commercial vehicles, and more specifically, to a compact bracket integrated design for a water-electricity connection structure and a vehicle lifting and load-bearing crossbeam. Background Art

[0002] With the rapid advancement of industrial technology, electric vehicles (EVs) with fast replacement modes have become an important trend in the transformation of the global automotive industry and have become one of the key drivers for promoting stable growth of the world economy. During the battery replacement process of electric commercial vehicles, especially when replacing batteries by lifting, if the water and electricity plugs under the vehicle chassis are not properly fixed, the relative position between the vehicle port and the battery pack port may be offset. This offset will not only increase the probability of failure during the battery replacement process, but may also lead to more serious consequences, such as damage to electrical system or cooling system components.

[0003] Given that the battery pack, battery pack bracket, front and rear lifting and load-bearing beams, and transverse support beams all need to be arranged along the longitudinal direction of the vehicle beam, the design of the vehicle chassis becomes extremely compact. While the existing vehicle structural design pursues compactness, it also brings new challenges - how to accurately install and fix the water and electricity connectors in such a limited space. The traditional beam layout method can no longer meet the high-precision positioning requirements of the fast battery replacement mode, which not only limits the effective use of the internal space of the battery pack, but also increases the weight of the entire vehicle, affecting the performance and endurance of the vehicle.

[0004] Therefore, an innovative solution must be found to overcome these obstacles. This requires not only improving the utilization of the internal space of the battery pack and reducing the weight of the vehicle, but also optimizing the space utilization efficiency of the longitudinal layout of the vehicle body beam. Only in this way can the stability of the water and electricity plugs during the battery replacement process be ensured, the risk of failure can be reduced, and the efficiency and reliability of the entire battery replacement system can be improved. This is an important issue currently faced in the design of electric commercial vehicles, and it is also the key to promoting the sustainable development of the electric vehicle industry and improving user experience. Summary of the invention

[0005] In order to solve the above problems, the present invention proposes an integrated compact bracket structure for supporting water and electricity sockets suitable for the fast battery replacement mode, which can not only improve the spatial layout inside the battery pack to make it more reasonable and efficient, but also ensure the stability of the water and electricity plugs, and effectively reduce the potential risks in the battery replacement process caused by unstable plugs.

[0032] In the front part of the integrated compact bracket for supporting the water and electricity joints, the left and right front supporting blocks 2 of the vehicle are fixedly connected to the vehicle beam 1 by bolts, so as to ensure the stable assembly of the supporting block bracket and the vehicle body.

[0033] The I-shaped front load-bearing crossbeam 4 is installed from bottom to top, and is fixed with the mounting holes of the left and right front lifting blocks by bolts. The waist holes of the crossbeam are connected with the threaded holes of the lifting blocks, thereby completing the installation of the front lifting bracket.

[0034] Two threaded inner holes are arranged at the bottom at the symmetrical midline position of the I-shaped front load-bearing cross beam 4 .

[0035] In addition, there are two protrusion structures on the outer plate surface of the beam, and internal threads are provided on the protrusions.

[0036] These four threaded holes constitute the fixing groove of the water interface of the vehicle-end battery pack 8, which is specifically used to fix the vehicle-end connector, thereby ensuring the stability and reliability of the water interface connector.

[0037] Two elliptical openings are designed in the front area of ​​the symmetrical midline of the I-shaped front load-bearing cross beam 4 to achieve the connection and installation of water pipes.
