AI Technical Summary
[0003]现有的三轮车车架包括货箱车架、人员车架以及固定两者的连接架，货箱车架需要承受大部分重量，因此会在货箱车架和连接架之间焊接撑杆，然而由于撑杆仅能够对货箱车架的前端进行加固支撑，当货物集中堆积在货箱的尾部时，货箱车架的后端承重较大，货箱车架存在弯曲断裂的风险
[0019]与现有技术相比，本实用新型具有的有益效果是：在电动三轮车车架上安装加固结构时，加固杆的底端穿过第一加固件上的通孔中，第一加固杆两端安装板上的紧固螺栓分别螺纹插接在货箱车架和连接架中，拧紧加固杆上的螺母使加固杆和第二加固件顶端的支撑架的货箱车架的中间端相支撑，利用加固撑杆、第二加固件和第一加固件分别与货箱车架的前端、中间端和后端进行支撑，提升了货箱车架的承重效果，降低了货箱车架受力过大出现弯曲断裂的情况。

Technical Field
[0001] This utility model relates to the field of tricycle frame technology, specifically a reinforcement structure for an anti-deformation electric tricycle frame. Background Technology
[0002] The frame, as the skeleton of the entire electric bicycle, largely determines the correctness and comfort of the riding posture, and also significantly impacts the rider's safety. Modern bicycle frames are primarily made of metal rods, which are typically hollow inside.
[0003] The existing tricycle frame includes a cargo box frame, a personnel frame, and a connecting frame that secures the two. The cargo box frame needs to bear most of the weight, so a support rod is welded between the cargo box frame and the connecting frame. However, since the support rod can only reinforce and support the front end of the cargo box frame, when the goods are piled up at the rear of the cargo box, the rear end of the cargo box frame bears a large load, and the cargo box frame is at risk of bending and breaking.

[0017] As a preferred embodiment of the anti-deformation electric tricycle frame reinforcement structure described in this utility model, the fastening mechanism includes a washer and a nut threaded onto the bottom end of the reinforcement rod, and the two nuts are respectively tightly connected to both sides of the first reinforcement component.
[0018] As a preferred embodiment of the anti-deformation electric tricycle frame reinforcement structure described in this utility model, the support frame has a U-shaped structure and is fitted into the bottom end of the cargo box frame:
