Embodiment Construction

[0014] like figure 2 , 3 As shown, arc frame slots 10 are arranged on the left and right A-pillars 6, 7, and the arc frame 8 is erected between the left and right A-pillars 6, 7, and its two ends are respectively arranged on the left and right A-pillars 6, 7. In the arc frame groove 10 of the right A-pillar 6,7, and connect with the left and right A-pillar 6,7 by strong angle piece 9. Both sides of the arc frame 8 are connected with strong corner pieces 9 . The arc frame is connected to the left and right A-pillars through strong corner pieces, which ensures the stability of the skeleton structure of the electric vehicle, makes the skeleton assembly more convenient and fast, and the arc frame positioning is accurate.

[0015] The strong corner piece 9 includes two connecting blocks perpendicular to each other, and the structural strengthening mechanism connects the connecting blocks, and the connecting blocks are provided with installation holes 901 . A group of connection...

Abstract

The invention relates to an electric vehicle framework connection structure. The electric vehicle framework connection structure comprises a left post A and a right post A, wherein a group of arc-shaped frames are erected between the left post A and the right post A; arc-shaped frame grooves are formed in the left post A and the right post A; and the two ends of each arc-shaped frame are respectively arranged in the arc-shaped frame grooves in the left post A and the right post A and are connected with the left post A and the right post A through powerful corner pieces. The arc-shaped frames are connected with the left post A and the right post A through the powerful corner pieces, so that the stability of an electric vehicle framework structure is ensured; the framework is assembled more conveniently and quickly; and the arc-shaped frames are positioned accurately.

Description

technical field [0001] The invention relates to a frame connection structure of an electric vehicle. Background technique [0002] An electric vehicle refers to a vehicle powered by a vehicle-mounted power supply, driven by a motor to drive the wheels, and conforming to the requirements of road traffic and safety regulations. Electric vehicles have no exhaust gas produced by internal combustion engine vehicles, and do not produce exhaust pollution. They are very beneficial to environmental protection and air cleanliness. They are almost "zero pollution". Their prospects are widely optimistic, but the current technology is not yet mature. The skeleton of the current electric vehicle, such as figure 1 As shown, the front windshield FRP part 1, the top cover aluminum profile 2, the rear top FRP part 3 and the rear pillar aluminum profile 4 are spliced ​​into one body, where A and B are bonding points, and the top arc rod 5 is welded when assembling on the skeleton. However, ...
