Description
Technical Field
The utility model relates to an electric motor car, in particular to lightweight aluminum alloy electric bicycle frame.
Background
The electric vehicle is also one of the main transportation means in China. The electric vehicle comprises a bearing system, an energy system, a driving system, a braking system, a running system and the like, wherein the bearing system comprises a frame of the electric vehicle, and the frame of the electric vehicle is one of core components of the electric vehicle, supports the weight of a vehicle body, a rider and all cargos and plays an important safety role.
The electric vehicle includes an electric vehicle for single person use or for riding a person, wherein a seat of the electric vehicle for single person use is a saddle type. The saddle is matched with a steel pipe on the electric vehicle through the steel pipe to install the saddle. Present steel pipe and electric motor car frame's back vent fixed connection specifically is for leaving the gap between the car back vent, and it is fixed through the welded mode with the car back vent respectively with the steel pipe wall, discovers in the in-service use process because steel pipe and car back vent area are not big, and the welding degree of difficulty is higher, leads to the fracture to take place between steel pipe and the car back vent, leads to the inspection unable to pass through, and the rework rate is than higher.
SUMMERY OF THE UTILITY MODEL
Utility model purpose: the utility model aims at providing a lightweight aluminum alloy electric bicycle frame solves above-mentioned problem.
The technical scheme is as follows: the utility model relates to a portable aluminum alloy electric bicycle frame, which comprises a pair of rear forks and a mounting tube for mounting a saddle; the mounting tube is fixedly connected with a connecting piece, and two ends of the connecting piece are fixedly connected with the tube wall of the corresponding rear fork in a welding mode.
Furthermore, the connecting piece is provided with an arc-shaped groove at the joint with the mounting tube, and the arc-shaped groove is used for increasing the connecting area of the connecting piece and the mounting tube.
Furthermore, a fixing opening is formed in one end, facing the gap between the two rear forks, of the connecting piece, and the edge of the fixing opening is fixedly connected with the pipe wall of the mounting pipe.
Furthermore, a supporting plate for supporting the installation pipe is arranged between the rear forks, a connecting port is formed in the contact part of the supporting plate and the installation pipe, and the heights of the two ends of the supporting plate are higher than the middle part of the supporting plate.
Furthermore, a rib plate used for increasing the connection strength is arranged between the supporting plate and the rear fork.
Has the advantages that: compared with the prior art, the utility model: through increase the connection piece between car back vent and installation pipe in order to improve the installation intensity between installation pipe and the car back vent to through connection piece and backup pad cooperation with the fixed mounting pipe of multi-angle, connection piece and backup pad carry out the fixed area of shape adjustment with increase and installation pipe, further improvement the fixed intensity of installation pipe and car back vent.

Detailed Description
As shown in fig. 1, a portable aluminum alloy electric bicycle frame comprises a pair of rear forks 1 and a mounting tube 2 for mounting a saddle; the mounting tube 2 is fixedly connected with a connecting piece 3, and two ends of the connecting piece 3 are fixedly connected with the tube wall of the corresponding rear fork 1 in a welding mode. On will installing pipe 2 and welding connection piece 3 through the welded mode in advance, then with connection piece 3 weld the pipe wall of car back fork 1 on, connection piece 3 compares in the welding degree of difficulty low and connection piece 3 and the welding area of car back fork 1 bigger with the car back fork 1 between car back fork 1 and the installation pipe 2 with the welding of the pipe wall welding of car back fork 1, and fixed strength is better.
In order to increase the connection area between the connecting sheet 3 and the mounting tube 2, the connecting sheet 3 is provided with an arc-shaped groove 4 at the joint with the mounting tube 2, and the arc-shaped groove 4 is used for increasing the connection area between the connecting sheet 3 and the mounting tube 2.
In order to further increase the connecting area between the connecting piece 3 and the mounting tube 2 and facilitate adjustment of the mounting angle of the opening of the mounting tube 2, a fixing opening 5 is formed at one end of the connecting piece 3 facing the gap of the two rear forks 1, and the edge of the fixing opening 5 is fixedly connected with the tube wall of the mounting tube 2.
As shown in figure 2, in order to fix the mounting tube 2 at a plurality of angles, a supporting plate 6 for supporting the mounting tube 2 is arranged between the rear forks 1, a connecting port 7 is arranged at the contact part of the supporting plate 6 and the mounting tube 2, and the heights of the two ends of the supporting plate 6 are higher than the middle part of the supporting plate.
In order to improve the connection strength between the support plate 6 and the rear fork 1, a rib plate 8 for increasing the connection strength is arranged between the support plate 6 and the rear fork 1.
