[0004] 2. Inconvenient battery pack replacement: The lack of a battery replacement structure is not conducive to the rapid operation of new energy vehicles.

[0005] 3. Poor installation accuracy: Deformation is easily generated during the welding process, affecting the installation accuracy of key components such as the battery pack.

[0006] 4. High manufacturing cost: There are many welds and high mold costs, which increase production costs. Utility Model Content

[0007] In order to solve the above problems, the utility model provides a new energy vehicle frame assembly with optimized structure, which has higher safety, installation accuracy, convenient battery replacement function, and lower production cost.

[0008] To achieve the above objectives, the present invention provides the following technical solutions, which mainly include:

[0011] Front longitudinal beam: It is equipped with multiple V-shaped crumple grooves to improve collision energy absorption capacity and enhance vehicle safety.

[0012] Battery pack holder assembly: Installed after welding to the frame, it includes a fixing bracket and a threaded sleeve. The bracket has a movable structure in three directions (X, Y, and Z) and can rotate horizontally and vertically to ensure accurate installation of the battery pack.

[0013] X-shaped reinforcement beam: installed on the front shock absorber bracket to increase the rigidity of the shock absorber mounting point and improve vehicle driving stability.

[0014] Guide groove: gradually shrinks in the longitudinal and transverse directions, and cooperates with the battery pack fixing seat assembly to control the installation position of the battery pack and ensure the convenience of battery replacement operation.

[0039] 1. Frame assembly manufacturing process

[0040] 1. Manufacturing of the main longitudinal beam 9 and the front longitudinal beam 4:

[0041] The main longitudinal beam 9 is processed by a pipe bending process to reduce the number of welds, lower production costs and reduce the risk of welding deformation.

[0042] The front longitudinal beam 4 is processed into a V-shaped crush groove through a precision stamping process to ensure that it can gradually crush and absorb energy during a collision.

[0043] 2. Installation and welding of beams:

[0044] The front crossbeam 7, the middle crossbeam 10, the third crossbeam 16, the fourth crossbeam 20 and the fifth crossbeam 25 are precisely positioned and welded to the main longitudinal beam 9 and the rear longitudinal beam 11 according to the design drawings to ensure the overall rigidity and torsional resistance of the frame.

[0046] An X-shaped reinforcement beam 6 is mounted on the front shock absorber bracket 5 and welded to ensure that the mounting point has high rigidity and stability.

[0047] 2. Installation and adjustment of battery pack bracket

[0048] 1. Frame adjustment before welding:

[0049] After the main frame structure is welded, it is adjusted to ensure that the welding process has not caused any deformation and the accuracy of the mounting holes remains within the tolerance range.

[0050] 2. Installation of battery pack bracket 12:

[0051] The battery pack bracket 12 is installed on the frame structure by welding. During the installation process, the threaded sleeve is used for lateral and longitudinal adjustment to ensure precise alignment between the bracket and the frame.

[0052] The battery pack bracket has the ability to move in three directions (X, Y, and Z) as well as horizontal and vertical rotation, which facilitates multi-directional fine-tuning of the battery pack during installation.

[0053] 3. Use of guide groove 27:

[0054] When installing the battery pack, the guide groove 27 matches the battery pack structure to ensure that the battery pack is automatically aligned in the longitudinal and transverse directions, facilitating rapid installation and replacement of the battery pack.

[0055] 3. Installation of cargo box, charging port and suspension system

[0056] 1. Installation of cargo box connection bracket:

[0057] The front connecting bracket 14, the middle connecting bracket 19 and the rear connecting bracket 22 of the cargo box are welded to the frame structure in sequence to ensure multi-point fixation between the cargo box and the frame.

[0058] 2. Installation of charging port bracket 15:

[0059] The charging port bracket 15 is installed on the side of the frame to facilitate users to quickly find the interface during charging operations.

[0060] 3. Installation of suspension system:

[0061] The leaf spring front lifting eye 18, the leaf spring rear lifting eye 23, the leaf spring limiting seat 21 and the rear shock absorber bracket 26 are installed in sequence to ensure that the vehicle's suspension system can work normally and provide good support and vibration reduction effects.

[0062] 4. Vehicle testing and performance verification

[0063] 1. Crash test:

[0064] After the vehicle is assembled, a collision test is carried out to verify the energy absorption effect of the V-shaped crumple groove, ensuring that the front longitudinal beam gradually collapses and absorbs the impact force during a collision.

[0065] 2. Battery replacement test:

[0066] The installation and removal of the battery pack are tested to verify the convenience of the guide groove 27 during the battery replacement process and the multi-directional adjustment capability of the battery pack bracket 12.

[0067] 3. Driving stability test:

[0068] The vehicle's driving performance under different road conditions is tested to ensure that the X-shaped reinforcement beam 6 improves the rigidity of the front shock absorber bracket and ensures the stability of the vehicle.

[0069] 5. Implementation Effect

[0070] Collision energy absorption: The V-shaped crumple groove design enables the vehicle to effectively absorb energy in the event of a collision, thereby improving safety.

[0071] Precise installation and convenient battery replacement: The multi-directional adjustment structure and guide groove design of the battery pack bracket make the installation and replacement of the battery pack more convenient, improving the operating efficiency of the vehicle.

[0072] High strength and low cost: The bending process of the main longitudinal beam reduces the length of the weld, reduces the cost of molds, and improves the strength and durability of the frame.

[0073] Stability: The installation of the X-shaped reinforcement beam enhances the rigidity of the front shock absorber bracket, ensuring the stability of the vehicle during driving.
