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 and 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 their quick-change mode, have become a key trend in the transformation of the global automotive industry and a key driver of stable global economic growth. During the battery swapping process in electric commercial vehicles, especially when replacing batteries by lifting, failure to properly secure the water and power plugs under the vehicle chassis can cause misalignment between the vehicle's ports and the battery pack's ports. This misalignment not only increases the probability of failure during the swap but can also lead to more serious consequences, such as damage to electrical or cooling system components.

[0003] Given that components such as the battery pack, battery pack bracket, front and rear lifting and load-bearing beams, and transverse support beams need to be arranged longitudinally along the vehicle beam, the vehicle chassis design becomes extremely compact. While pursuing compactness, existing vehicle structural designs also bring new challenges - how to accurately install and secure 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 rapid battery swap mode. This 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 vehicle's performance and endurance.

[0004] To overcome these obstacles, innovative solutions must be found. This requires not only improving the internal space utilization of the battery pack and reducing vehicle weight, but also optimizing the space efficiency of the longitudinal layout of the vehicle body frame. Only in this way can the stability of the water and electricity plugs during the battery swap process be ensured, reducing the risk of failure and thus improving the efficiency and reliability of the entire battery swap system. This is a critical issue currently facing electric commercial vehicle design and is key to promoting the sustainable development of the electric vehicle industry and improving the 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. It can not only improve the spatial layout inside the battery pack, making 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.

The I-shaped front load-bearing crossbeam has two threaded inner holes on its symmetrical center line and a raised structure with an internal thread on its outer side. This raised structure is used to fix the water interface of the vehicle-end battery pack;

[0008] The rear part of the bracket includes a vehicle rear lifting block, a C-shaped rear load-bearing crossbeam and an electric plug fixing support, wherein the vehicle rear lifting block is fixedly connected to the vehicle frame by bolts; the C-shaped rear load-bearing crossbeam is installed from the bottom and fixedly connected to the mounting holes of the vehicle rear lifting blocks on the left and right sides by bolts; the electric plug fixing support is fixedly connected to the mounting hole of the C-shaped rear load-bearing crossbeam through its waist hole.

[0009] The technical solution further defined in the present invention is:

[0010] Furthermore, the I-shaped front load-bearing crossbeam is provided with an elliptical opening in the front area of ​​its symmetrical midline for connection and installation of water pipes.

[0011] Furthermore, the electric plug fixing support is a parallelogram structure, and is provided with four threaded holes at its bottom for installing the vehicle-end electric plug.

[0012] Furthermore, the vehicle front lifting block is connected to the vehicle beam via at least one bolt.

[0013] Furthermore, the C-shaped rear load-bearing crossbeam is connected to the rear lifting block of the vehicle by at least one bolt.

[0014] Furthermore, the electric plug fixing support is connected to the C-shaped rear load-bearing beam by at least one bolt.

[0015] Furthermore, the raised structure on the outer plate surface of the I-shaped front load-bearing crossbeam is used to fix the water interface of the battery pack at the vehicle end and ensure the stability and reliability of the water interface.

[0016] Furthermore, the size of the pair of elliptical openings is adapted to the water pipes, and the design of the elliptical openings takes into account the compatibility and installation convenience of the water system, ensuring a reliable connection between the water pipes and the beams.

[0017] Furthermore, the positions and sizes of the four threaded holes are specifically designed to accommodate a specific vehicle-end electrical plug.

[0018] Furthermore, the overall design of the bracket takes into account the requirements of space compactness and lightweight, which improves the internal space utilization of the battery pack and optimizes the space utilization efficiency of the vehicle body frame in the longitudinal layout.

[0019] The beneficial effects of this invention include improving the utilization of the battery pack's internal space, reducing vehicle weight, and optimizing the longitudinal space utilization of the vehicle's frame. This integrated bracket not only improves the internal spatial layout of the battery pack but also ensures the stability of the water and electricity plugs, effectively reducing potential risks during battery replacement, thereby improving the efficiency and reliability of the vehicle's battery replacement process.

[0036] In the front part of the integrated compact bracket for lifting the water and electricity joints, the left and right vehicle front lifting blocks 2 are fixedly connected to the vehicle beam 1 by bolts, ensuring the stable assembly of the lifting block bracket and the vehicle body.

[0037] The I-shaped front load-bearing crossbeam 4 is installed from bottom to top and fixed with bolts and the mounting holes of the left and right front lifting blocks. The waist holes of the crossbeam are connected to the threaded holes of the lifting blocks, thereby completing the installation of the front lifting bracket.

[0038] Two threaded inner holes are provided at the bottom of the I-shaped front load-bearing crossbeam 4 at the symmetrical midline position.

[0039] In addition, there are two protrusions on the outer plate surface of the beam, and internal threads are provided on the protrusions.
