Abstract
The utility model relates to an electric tricycle structure roof beam, back frame (5), front truck frame (6), back frame (5) both sides fixed mounting back longeron (1), fixed mounting back roof beam structure (3) between two back longerons (1), front truck frame (6) both sides fixed mounting front longitudinal beam (2), longeron tie-beam (4) around two front longitudinal beam (2) outside surfaces installed respectively, anterior back longeron (1) fixed connection front and back longeron tie-beam (4) that have certain radian, front longitudinal beam (2) one end fixed connection back roof beam structure (3), can reduce the cost reduction and make the degree of difficulty, can have through structural design reinforcing structure roof beam intensity in the time that does not increase weight.
Description
Technical Field
The utility model relates to a structure roof beam specifically is electric tricycle structure roof beam.
Background
A framework type lower vehicle body and a sheet metal type upper vehicle body combined vehicle body assembly is characterized in that a traditional lower vehicle body is of a stamping sheet metal longitudinal beam and cross beam structure, all parts are connected through spot welding, but the development cost of stamping part dies and clamps is high, the development cost requirements of low-cost three-wheeled motor vehicles and electric vehicles cannot be met, and meanwhile, a rear longitudinal beam and a front longitudinal beam of a normal lower vehicle body are through type integrated beams and are limited by the fact that the materials of the rear longitudinal beam and the front longitudinal beam cannot meet the requirement of heavy-weight loading.
Disclosure of Invention
To the problem that above-mentioned prior art exists, the utility model provides an electric tricycle structure roof beam can reduce the cost reduction and make the degree of difficulty, can have through structural design reinforcing structure roof beam intensity in not gaining in weight.
In order to achieve the above object, the utility model discloses a following technical scheme realizes: electric tricycle structure roof beam, including back longeron, front longitudinal beam, back roof beam structure, front and back longeron tie-beam, back frame, front truck frame, back frame both sides fixed mounting back longeron, fixed mounting back roof beam structure between two back longerons forms the latter half of whole frame, front truck both sides fixed mounting front longitudinal beam, two front longitudinal beam outside surfaces install front and back longeron tie-beams respectively, the front portion has the back longeron fixed connection front and back longeron tie-beam of certain radian, front longitudinal beam one end fixed connection back roof beam structure, form a structure that sinks with the help of the anterior radian of back longeron and back roof beam structure, effectively promote frame structural strength.
The rear longitudinal beam, the front longitudinal beam, the rear beam frame, the front and rear longitudinal beam connecting beam, the rear frame and the front frame are connected in a welding mode, and therefore the overall strength is guaranteed.
The rear longitudinal beam, the front longitudinal beam and the rear beam frame are all made of rectangular tubes, and cost is reduced.
The front and rear longitudinal beam connecting beams are made of steel plates through stamping.
The middle section of the rear beam frame is provided with an arched bend, and the surface of the rear beam frame is provided with a reinforcing rib, so that the structural strength is ensured, and the arrangement of a transmission shaft is not influenced.
Borrow by above-mentioned scheme, the utility model discloses at least, have following advantage: compared with the conventional through type integrated beam, the beam has higher strength under the same weight, and can effectively reduce the production cost.

Detailed Description
The technical solution of the present invention will be clearly and completely described with reference to the accompanying drawings.
In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
As shown in fig. 1 and fig. 2, the structural beam of the electric tricycle comprises a rear longitudinal beam 1, a front longitudinal beam 2, a rear beam frame 3, front and rear longitudinal beam connecting beams 4, a rear frame 5 and a front frame 6, wherein the rear longitudinal beam 1 is fixedly arranged on two sides of the rear frame 5, the rear beam frame 3 is fixedly arranged between the two rear longitudinal beams 1 to form a rear half part of the whole frame, the front longitudinal beam 2 is fixedly arranged on two sides of the front frame 6, the front and rear longitudinal beam connecting beams 4 are respectively arranged on the outer side surfaces of the two front longitudinal beams 2, the front part of the rear longitudinal beam 1 with a certain radian is fixedly connected with the front and rear longitudinal beam connecting beams 4, the rear beam frame 3 is fixedly connected with one end of the front longitudinal beam 2, a sinking structure is formed by means of the front radian of the rear longitudinal beam 1 and the rear beam frame 3, and the structural strength of the frame is effectively improved.
The rear longitudinal beam 1, the front longitudinal beam 2, the rear beam frame 3, the front and rear longitudinal beam connecting beam 4, the rear frame 5 and the front frame 6 are connected by welding, so that the integral strength is ensured.
The rear longitudinal beam 1, the front longitudinal beam 2 and the rear beam frame 3 are all made of rectangular pipes, and cost is reduced.
The front and rear longitudinal beam connecting beams 4 are made of steel plates through stamping.
The middle section of the rear beam frame 3 is provided with an arched bend, and the surface of the arched bend is provided with a reinforcing rib, so that the structural strength is ensured, and the arrangement of a transmission shaft is not influenced.
Has the beneficial effects that: compared with the conventional through type integrated beam, the structural beam has higher strength under the same weight through the improvement of excellent structural design and processing scheme, and the production cost can be effectively reduced.
