Description

Technical Field

[0001] The utility model relates to the technical field of electric tricycles, in particular to a novel electric tricycle with an integrated vehicle box and frame. Background Art

[0002] As a green and environmentally friendly means of transportation, electric tricycles have garnered widespread attention and popularity in the domestic market in recent years. With China's increasing emphasis on environmental protection and new energy, the market prospects for electric tricycles are expanding, and their exceptionally high cost-effectiveness and convenience have earned widespread recognition. However, with increasing usage, tricycle accidents have also increased dramatically, placing higher demands on tricycle safety and reliability. With the growing number of domestic users and increased overseas exports, the transportation cost of tricycles has become increasingly sensitive. The unusually shaped frame and carriage design of traditional tricycles results in extremely low space utilization during transportation, resulting in consistently high transportation costs. This is particularly true for export-oriented tricycle companies, where transportation costs have significantly reduced their market competitiveness. Utility Model Content

By setting the tricycle chassis body 3, the tricycle body underframe body 5 and the keel body 6, and by using the thickened steel pipe design for the tricycle chassis body 3, the tricycle body underframe body 5 and the keel body 6, and the tricycle body and the tricycle frame are integrated into one design, the four-point connection method between the old tricycle body and the frame is solved, which causes the tricycle body to directly crash into the tricycle cockpit when hit by the rear end, threatening the safety of the driver.

[0024] Three keel bodies 6 are arranged in sequence from left to right along the surface of the tricycle chassis body 3 bracket. The bottom of the tricycle triangle bracket body 1 is installed at the front end of the tricycle chassis body 3, and the tricycle triangle bracket body 1 is connected to the three keel bodies 6 through the tricycle chassis body 3. By setting the tricycle body frame body 5 and the integrated design of the tricycle body frame, the material used in the body frame is reduced and the structural strength of the tricycle is enhanced, which has both performance ratio and cost performance.

[0025] A tricycle front gear mounting hole 7 is provided on the front of the tricycle chassis body 3 , a tricycle triangle bracket mounting hole 8 is provided on the outside of the tricycle chassis body 3 , and a tricycle seat mounting hole 9 is provided in the middle of the tricycle chassis body 3 .

[0026] The rear portion of the tricycle chassis body 3 is fixedly mounted on the tricycle carriage bottom frame support frame body 10 , and the tricycle carriage bottom frame support frame body 10 is mounted on the back side of the tricycle seat mounting hole 9 .

[0030] Working principle: When installing the integrated box frame of the electric tricycle, first install the tricycle triangle bracket body 1 to the front section of the tricycle chassis body 3 through the tricycle triangle bracket installation hole 8, and then install the tricycle seat bracket 4 to the middle of the tricycle chassis body 3 through the tricycle seat installation hole 9, and then install the tricycle chassis keel installation hole 13 and the bottom of the tricycle box frame body 5 through the riveting process, so that the keel body 6 is fixed to the tricycle box frame body 5, thereby completing the installation of the integrated box frame of the electric tricycle, and all structural parts are designed according to the planarization requirements, which simplifies the production, stacking and transportation, and reduces the cost.

The tricycle chassis body 3, the tricycle body frame body 5 and the keel body 6 are all designed with thickened steel pipes, and the tricycle body and the tricycle frame are designed as one body. This solves the problem of the four-point connection between the old tricycle body and the frame, which causes the tricycle body to directly crash into the tricycle cockpit when it is hit from the rear end, threatening the safety of the driver. Secondly, the integrated design of the tricycle body frame not only reduces the material used in the body frame, but also strengthens the structural strength of the tricycle. It has both performance ratio and cost-effectiveness. The modular design and assembly of the tricycle integrated body frame not only improves the efficiency of the production line, but also saves costs, and provides a convenient foundation for the real mass production and assembly of tricycles.
