Abstract
The utility model relates to an automobile frame field, and the front beam aims to provide a front beam which a welding spot between an external board and an internal board is not easy to break when the front end of an automobile suffers low speed collision. The front beam comprises the external board and the internal board, the shapes of the external board and the internal board are arc shape that a protruding surface is in accordance with the front end direction of the automobile, a plurality of liquid leaking grooves are formed in back side surface of the external board along length direction. The front beam is characterized in that a plurality of external wave gears are arranged on the back side surface on the external board along the length direction; a plurality of internal wave gears are arranged on the front side surface of the internal board along the length direction; the external wave gears and the internal wave gears are alternately embedded and welded through the welding spots arranged along a plurality of the external boards and internal boards length direction. The welding spot of the front beam between the external boards and the internal boards are not easy to break when the automobile suffers low speed collision.
Description
Technical field
The utility model relates to the automobile chassis frame field, the front cross rail that the solder joint when especially a kind of automotive front end is subject to low speed collision between outside plate and inner panel is not easy to snap.
Background technology
The utility model of Chinese patent notification number CN202208317U discloses a kind of automobile chassis frame, this automobile chassis frame comprises front vehicle frame and rear vehicle frame, described front vehicle frame is captiveed joint with rear vehicle frame, described front vehicle frame comprises front cross rail and two curb girders, and described two curb girders lay respectively at the both sides of described front cross rail and captive joint with described front cross rail.Common front cross rail is as shown in Figure 2: comprise outside plate 1 and inner panel 2, in order to improve anti-collision ability, the shape of outside plate 1 and inner panel 2 is the convex surface arc consistent with the front extreme direction of automobile, the trailing flank of outside plate 1 is provided with several liquid leakage tanks 11 along its length, and the leading flank of the trailing flank of outside plate 1 and inner panel 2 is along its length by several solder joint spaced apart 3 welding; The trailing flank of the outside plate 1 between per two solder joints 3 and the leading flank of inner panel 2 also are arc, the weak point that this front cross rail exists is: when automotive front end is subject to the distortion of low speed collision outside plate and can produces the opposite conicity force of both direction, the solder joint adjacent with collision place snaps under two conicity force effects easily; Therefore, the front cross rail that the solder joint when designing a kind of automotive front end and being subject to low speed collision between outside plate and inner panel is not easy to snap becomes problem demanding prompt solution.
The utility model content
The purpose of this utility model is to have the deficiency that the solder joint adjacent with collision place snaps easily when automotive front end is subject to the distortion of low speed collision outside plate, the front cross rail that the solder joint when providing a kind of automotive front end to be subject to low speed collision between outside plate and inner panel is not easy to snap in order to overcome present front cross rail.
Concrete technical scheme of the present utility model is:
A kind of front cross rail comprises outside plate and inner panel; The shape of described outside plate and inner panel is the convex surface arc consistent with the front extreme direction of automobile, and the trailing flank of outside plate is provided with several liquid leakage tanks along its length; It is characterized in that the trailing flank of described outside plate is provided with several external wave teeth along its length; The leading flank of described inner panel is provided with ripple tooth in several along its length; Described external wave tooth and Nei Bo tooth replace chimeric and weld along the solder joint that the length direction of outside plate and inner panel is provided with by several.When automotive front end was subject to the distortion of low speed collision outside plate, because the effect of external wave tooth and Nei Bo tooth, two conicity forces that act on the solder joint adjacent with collision place reduced, and make solder joint be not easy to snap.This front cross rail solder joint between outside plate and inner panel when automotive front end is subject to low speed collision is not easy to snap.
As preferably, being shaped as of described external wave tooth is trapezoidal, and being shaped as of interior ripple tooth is trapezoidal.Making and effect are better easily.
As preferably, described liquid leakage tank is positioned at the middle part of external wave tooth small end.Easy to make.
Compared with prior art, the beneficial effects of the utility model are: one. this front cross rail solder joint between outside plate and inner panel when automotive front end is subject to low speed collision is not easy to snap.Two. the shape of described external wave tooth and Nei Bo tooth be trapezoidal easy making and effect better.Three. it is easy to make that described liquid leakage tank is positioned at the middle part of external wave tooth small end.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model;
Fig. 2 is the structural representation of existing front cross rail;
Fig. 3 is the enlarged drawing at A place among Fig. 1.
Among the figure: outside plate-1, liquid leakage tank-11, external wave tooth-12, inner panel-2, interior ripple tooth-21, solder joint-3.
The specific embodiment
Below in conjunction with shown in the accompanying drawing the utility model is described further.
Shown in accompanying drawing 1, accompanying drawing 3: a kind of front cross rail comprises outside plate 1 and inner panel 2; The shape of described outside plate 1 and inner panel 2 is the convex surface arc consistent with the front extreme direction of automobile; The trailing flank of described outside plate 1 has 16 external wave teeth 12 along its length; The leading flank of described inner panel 2 has 17 interior ripple teeth 21 along its length; Described external wave tooth 12 and Nei Bo tooth 21 replace chimeric and weld by 12 solder joints 3 that have along the length direction of outside plate 1 and inner panel 2.The trailing flank of outside plate 1 has 14 liquid leakage tanks 11 along its length, and in the present embodiment, being shaped as of described external wave tooth 12 is trapezoidal; Being shaped as of described interior ripple tooth 21 is trapezoidal; Described liquid leakage tank 11 is positioned at the middle part of external wave tooth 12 small ends.
When automotive front end was subject to 1 distortion of low speed collision outside plate, because the effect of external wave tooth 12 and Nei Bo tooth 21, two conicity forces that act on the solder joint 3 adjacent with collision place reduced, and make solder joint 3 be not easy to snap.
The beneficial effects of the utility model are: this front cross rail solder joint between outside plate and inner panel when automotive front end is subject to low speed collision is not easy to snap.The shape of described external wave tooth and Nei Bo tooth be trapezoidal easy making and effect better.It is easy to make that described liquid leakage tank is positioned at the middle part of external wave tooth small end.
It is apparent to one skilled in the art that the utility model can be changed into various ways, and such change is not thought and broken away from scope of the present utility model.The apparent modification of the technical personnel to described field that all are such will be included within the scope of this claim.
