As important assembly components, these vehicle frames and carriage components are used in many places during vehicle preparation. When in use, the vehicle frame is used as the bottom support component of the carriage, and further welding and assembly of the carriage can be carried out on the vehicle frame, making the carriage safer and more stable during assembly and meeting the work requirements of vehicle assembly.

[0003] In the prior art: CN201320891944.3, a new type of electric vehicle frame, includes a front tube, a middle tube, a rear tube, a lower fork, and an upper fork. The front tube, middle tube, and rear tube are connected in sequence from front to back. One end of the lower fork is connected to the rear end of the middle tube, and the other end is connected to the lower end of the upper fork. The upper end of the upper fork is connected to the upper end of the rear tube. A metal frame is welded to the upper end of the middle tube. Folding pedals are embedded on both the left and right sides of the metal frame. A sprocket is provided at the rear of the metal frame. When the pedals are not needed, they can be folded up, which not only makes the driving route narrower and ensures safety.

[0004] In the prior art, the pedals are protected from being exposed to rain or sunlight, thereby increasing the service life of the pedals. However, the vehicle frame in the prior art cannot be assembled efficiently, and at the same time, when in use, it cannot meet the need for routing transmission cables, affecting the overall use effect of the vehicle frame.

[0006] The utility model is realized by adopting the following technical scheme: An easily assembled bottom sub-frame is provided with a main crossbeam, and assembly holes are arranged on the main crossbeam. A front vehicle frame and a rear vehicle frame are arranged in the assembly holes. The front vehicle frame and the rear vehicle frame are symmetrically distributed on both sides of the main crossbeam. An intermediate beam is arranged on the front vehicle frame. Side beams are arranged on both sides of the intermediate beam. Support beams are arranged between the side beams and the intermediate beam. A rear support beam is arranged on the rear vehicle frame. Side brackets are arranged on both sides of the rear support beam. A wire routing component is arranged on the main crossbeam. The wire routing component is a wire routing channel. A locking component is arranged between the wire routing channel and the main crossbeam.

[0007] The locking component is a locking slot. The locking slot is fixedly welded to the main crossbeam, and an assembly space is arranged on the locking slot.

[0008] A wiring duct is snapped into the described assembly space. A locking hole is provided on the described locking slot, and a locking bolt is provided in the locking hole.

[0009] An assembly plate is provided on the described main crossbeam. An assembly position is provided on the assembly plate, and an assembly bracket is provided at the assembly position.

[0010] The assembly bracket and the assembly position are fixed by welding. An assembly round hole is provided on the assembly bracket, and a locking threaded rod is provided in the assembly round hole.

[0011] Compared with the prior art, when the present utility model is in use, the main crossbeam can be used as an intermediate support member. A front frame and a rear frame are provided on both sides of the main crossbeam. The front frame and the rear frame can be used to further improve the supporting force on both sides of the frame. A wiring component is provided on the main crossbeam. The wiring component can facilitate the routing of transmission cables, so that the transmission cables have a fixed routing position, meeting the routing requirements. When the wiring component needs to be further fixed, the locking slot can be used to fix the wiring component, enabling the wiring component to be effectively fixed and providing a certain transmission space for the transmission cables when the frame is in use.
