The electric car main frame is of the integrally-formed metal square tube structure, so the electric car main frame is high in strength and flexibility, breakage and sealing-off can be avoided in the using process, the quality of the electric car is improved, and the service life of the electric car is prolonged.
Description
Technical field
The utility model relates to vehicle technology field, relates in particular to the battery-driven car main body frame that a kind of one-body molded intensity is high.
Background technology
Battery-driven car is divided into alternating current electric vehicle and DC electric car.Usually said battery-driven car is using battery as energy source, by the parts such as controller, motor, is mechanical energy by electric energy conversion, changes the car of speed to control size of current.First battery-driven car produced in 1834, and it is driven by DC machine, and even to this day, great variety has occurred battery-driven car, and type is also varied.The type of drive of battery-driven car mainly contains three kinds: one is that hub-type drives, and one is that middle drives, and last a kind of suspension type drives.On market, Electrical Bicycle is taking wheel hub driving as main, and wheel hub drives with back-wheel drive as well, and f-w-d performance is relatively poor.The riding position of battery, considers from car load balance and HOP ON–HOP OFF, with battery be positioned over vehicle frame inclined tube or standpipe position for well, the battery of configuration is economical and practical lead-acid battery substantially.Most of Electrical Bicycles adopt 36V12AH lead-acid battery; The battery of 24V12AH is because mileages of continuation is shorter, and it is fewer that customer selects.
The vehicle frame of existing Electrical Bicycle or battery-operated motor cycle adopts steel pipe or various section bar to weld according to certain shape mostly, or adopt fastening means to connect, the manufacture of this vehicle frame exists manufacturing process loaded down with trivial details, selection is limited, vehicle frame own wt is large, the defects such as cost of manufacture height, and made vehicle frame exists some position because secondary processing easily occurs that distribution of stress inequality finally causes the hidden danger of quality problems such as rupturing, crack, brings huge threat to riding personnel's the security of the lives and property.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of battery-driven car main body frame, described main body frame is used integrated metal side tube structure, has intensity high, and elasticity is strong, can in the process using, not there is not fracture and snap phenomenon, improve quality and the service life of battery-driven car.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of battery-driven car main body frame, is characterized in that: described vehicle frame adopts integrated metal side tube structure, comprises the first horizontal part that is positioned at the leftmost side; One end is connected with the first horizontal part, the first curve that the other end is connected to downward-extension and with the second horizontal part; One end is connected with the first curve, the second horizontal part that the other end is connected with the second curve; And one end is connected with the second horizontal part, the other end upwards extends to form free-ended the second curve.
Preferably, described metal side tube structure before or after side be provided with reinforced rib.
Preferably, described reinforced rib is linear, curvilinear figure or fold-line-shaped.
Preferably, the angle of described the first horizontal part and the first curve is 45 °-60 °.
Preferably, the angle of described the first horizontal part and the first curve is 60 °.
Preferably, the angle of described the second horizontal part and the second curve is 60 °-75 °.
Preferably, the angle of described the second horizontal part and the second curve is 75 °.
The beneficial effect that adopts technique scheme to produce is: described battery-driven car main body frame adopts a metal side tube to carry out bending manufacture by angle bender and forms, without carrying out other processing, so just, reduced the impact on the load-carrying capacity of part own, bulk strength is high, and the horizontal part on it and curve coordinate, and elasticity is strong, can in the process using, not there is not fracture and snap phenomenon, use safety, quality and the service life of having improved battery-driven car.In addition, be welded with reinforced rib in the outside of described metal side tube structure, further improved the bulk strength of vehicle frame, without welding process, reduced operation, reduced productive costs, there is good popularization and prospect of the application.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is main TV structure schematic diagram of the present utility model;
Fig. 2 is cross-sectional plane sectional structure schematic diagram of the present utility model;
Wherein: 1, the first horizontal part 2, the first curve 3, the second horizontal part 4, the second curve 5, reinforced rib.
Detailed description of the invention
As shown in Figure 1-2, a kind of battery-driven car main body frame, described vehicle frame adopts integrated metal side tube structure, comprises the first horizontal part 1; One end is connected with the first horizontal part 1, the first curve 2 that the other end is connected to downward-extension and with the second horizontal part 3; One end is connected with the first curve 2, the second horizontal part 3 that the other end is connected with the second curve 4; And one end is connected with the second horizontal part 3, the other end upwards extends to form free-ended the second curve 4.Generally, the angle of described the first horizontal part 1 and the first curve 2 is 45 °-60 °, and the angle of described the second horizontal part 3 and the second curve 4 is 60 °-75 °, need to make suitable adjustment according to the integral structure of battery-driven car.In order further to promote bulk strength, side is provided with reinforced rib 5 before or after described metal side tube structure, and described reinforced rib 5 is linear, curvilinear figure or fold-line-shaped.
Described battery-driven car main body frame adopts a metal side tube to carry out bending manufacture by angle bender and forms, without carrying out other processing, so just, reduced the impact on the load-carrying capacity of part own, bulk strength is high, and the horizontal part on it and curve coordinate, and elasticity is strong, can in the process using, not there is not fracture and snap phenomenon, use safety, quality and the service life of having improved battery-driven car.In addition, be welded with reinforced rib in the outside of described metal side tube structure, further improved the bulk strength of vehicle frame, without welding process, reduced operation, reduced productive costs, there is good popularization and prospect of the application.
Applied specific case herein principle of the present utility model and embodiment thereof are set forth, the explanation of above embodiment is just with helping understand method of the present utility model and core concept thereof.It should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not depart from the utility model principle, can also carry out some improvement and modification to the utility model, these improvement and modification also fall in the protection domain of the utility model claim.
