Abstract
The utility model discloses an electric vehicle frame, including head tube, girder pipe and be located the frame both sides with girder pipe fixed connection's limit pipe, the limit pipe extends to the back upper place and forms rear of a vehicle frame, frame both sides limit pipe middle part directly is provided with cushion pipe, its characterized in that: the frame both sides limit pipe horizontal position section fixedly connected with attaches the pipe, forms two bilateral tubular construction from top to bottom. The utility model discloses an it attaches the pipe to increase on the pipe of both sides limit to connect girder pipe and bilateral pipe through the box core. Make the frame form about bilateral tubular construction, greatly increased the intensity of frame. Can make the frame indeformable in long -time use. Increase the protective capacities that impact the frame side more, guaranteed the safety of vehicle. Because this frame part annex adopts the stamping workpiece, has also increased the intensity of automobile body in the equipment precision that increases the frame.
Description
Technical field
The utility model belongs to vehicle technology field, particularly relates to a kind of electromobile frame.
Background technology
Electromobile frame is generally managed by head tube, main-beam pipe and the limit be fixedly connected with described main-beam pipe that is positioned at vehicle frame both sides.Limit pipe extends to form rear frame rearwardly and upwardly, is directly provided with cushion pipe in the middle part of limit pipe described in vehicle frame both sides.In prior art, limit pipe is each one of both sides, and direct and main-beam pipe is welded together to form vehicle frame entirety.The stressed framework be mainly all made up of limit pipe of vibrations of jolting of road generation during normal vehicle operation bears, and battery-driven car uses back to manage for a long time and easily deforms.In addition, the structure of existing vehicle frame longitudinally has larger intensity when occurring to clash into, but more easily deforms after meeting with shock for side direction, even ruptures, causes car body to damage, affect vehicle safety.In order to increase frame strength, normal increase limit pipe diameter and the thickness of adopting realizes, and will increase the cost of vehicle frame like this, reduce production efficiency.
Summary of the invention
The utility model object is to provide that a kind of intensity is high for the defect of prior art, simple and convenient assembly, electromobile frame that vehicle frame package size error is little.
The utility model for achieving the above object, adopts following technical scheme:
A kind of electromobile frame, the limit be fixedly connected with described main-beam pipe comprising head tube, main-beam pipe and be positioned at vehicle frame both sides is managed, described limit pipe extends to form rear frame rearwardly and upwardly, cushion pipe is directly provided with in the middle part of limit pipe described in vehicle frame both sides, it is characterized in that: described in vehicle frame both sides, limit pipe level attitude section is fixedly connected with attached pipe, forms the bilateral tubular construction of upper and lower two.
It is further characterized in that: described main-beam pipe is "T"-shaped to be connected on pedal bar connection pipe; The limit pipe of described pedal bar connection pipe two ends, vehicle frame both sides is fixedly connected with the box core of attached pipe by vehicle frame both sides.
Further: described main-beam pipe is provided with transverse tube, described transverse tube two ends and box core upper end, both sides form four strong points, and the described strong point is fixedly connected with pedal support.
Its further feature is also: described attached pipe side-lower is connected with side stand adapter plate, and described side stand adapter plate is pressed sheet, is welded on described attached pipe by " C " tee section attaching parts.
Front battery case and rear battery case is provided with, described front battery case and rear battery case arranged in step shape between the bilateral tubular construction of described vehicle frame both sides; Described front battery case and rear battery case integrated punching shaping, the front cabinet plate of described front battery case is fixedly connected on described pedal bar connection pipe, and described rear battery case side is fixedly connected on the attached pipe in both sides; Be fixedly connected on the attached pipe in both sides by a support gusset bottom described front battery case.
The utility model by increasing attached pipe on dual-side pipe, and connects main-beam pipe and bilateral pipe by box core.Make vehicle frame form upper and lower bilateral tubular construction, considerably increase the intensity of vehicle frame.Vehicle frame can be made indeformable in long use procedure.More add the protective capacities of vehicle frame side impact, ensure that the safety of vehicle.Because this frame section annex adopts blanked part, while the assembly precision increasing vehicle frame, too increase the intensity of car body.In addition, battery case integrated punching of the present utility model is shaping, and the frame mode of employing pull-up, subiculum, front company is connected with bilateral tubular construction, thus enhances the load-carrying capacity of battery case greatly, prevent battery case from loading after battery, long-term vibration and the battery that causes come off problem.Further, owing to have employed upper and lower bilateral tubular construction, while guarantee frame strength, the reduction that the diameter of single limit pipe and thickness can be suitable.Thus make vehicle frame more light, reduce vehicle frame cost.

Detailed description of the invention
As shown in Figure 1, 2, a kind of electromobile frame, comprise head tube 1, main-beam pipe 2 and be positioned at the limit pipe 8 be fixedly connected with described main-beam pipe 2 of vehicle frame both sides, described limit pipe 8 extends to form rear frame rearwardly and upwardly, cushion pipe 11 is directly provided with in the middle part of limit pipe 8 described in vehicle frame both sides, described in vehicle frame both sides, limit pipe 8 level attitude section is fixedly connected with attached pipe 9, forms the bilateral tubular construction of upper and lower two.Described main-beam pipe 2 is "T"-shaped to be connected on pedal bar connection pipe 4; The limit pipe 8 of described pedal bar connection pipe 4 two ends, vehicle frame both sides is fixedly connected with the box core 5 of attached pipe 9 by vehicle frame both sides.
Head tube 1 first welds with main-beam pipe 2 and welds in advance, appears in Frame Welding operation after double end bore hole operation with absolute version, ensures the right alignment requirement of head tube to greatest extent.
As shown in Figure 1,3, described main-beam pipe 1 is provided with transverse tube, described transverse tube two ends and box core 5 upper end, both sides form four strong points, the described strong point are fixedly connected with pedal support 3.The each part of pedal support 3 assembly welding in advance, then appears in vehicle frame assembly welding operation with independently form, both enhanced productivity, and can ensure welding precision again.
As shown in Fig. 1,4, described attached pipe 9 side-lower is connected with side stand adapter plate 6, and described side stand adapter plate 6 is pressed sheet, is welded on described attached pipe 9 by " C " tee section attaching parts.The overall cold-punching molding of side stand adapter plate 6, intensity is reliable; And be connected by pipe 9 attached with vehicle frame after a stamping transition, after vehicle can be avoided to use for a long time, this limit, position pipe is by the phenomenon of drawing crack.
As shown in Figure 1,5, between the bilateral tubular construction of described vehicle frame both sides, be provided with front battery case 7 and rear battery case 10, described front battery case 7 and rear battery case 10 arranged in step shape; Described front battery case 7 and rear battery case 10 integrated punching shaping, the front cabinet plate of described front battery case 7 is fixedly connected on described pedal bar connection pipe 4, and described rear battery case 10 side is fixedly connected on the attached pipe 9 in both sides; Be fixedly connected on the attached pipe 9 in both sides by a support gusset bottom described front battery case.The overall punch forming of battery case, adopts the frame mode of pull-up, subiculum, front company, is different from the structure of general vehicle frame battery case only pull-up or subiculum; Avoid the hidden danger that battery case in use procedure comes off.
