Abstract
The utility model discloses a pedestrian protects roof beam, the protection roof beam main part that just has the U type including integrative injection moulding, protection roof beam main part include the outer wall and with a plurality of U type grooves of wall connection, and two adjacent U type grooves are reverse connects. The utility model discloses a pedestrian protects roof beam through the structure in a plurality of reverse U type grooves of connecting, when the car bumps with the pedestrian, because the structure atress is even, can reduce stress concentration effectively, while simple structure, the production of being convenient for.
Description
Technical field
The utility model relates to automobile correlative technology field, particularly a kind of pedestrian protecting beam.
Background technology
The vehicle body of automobile generally can be provided with pedestrian protecting beam, to reduce automobile when colliding pedestrian to the infringement that pedestrian lower leg produces.
Current injection moulding pedestrian protecting beam is mainly Ω shaped main body structure, and mould structure is complicated, and pts wt is heavier, the high and function singleness of cost.
Utility model content
Based on this, be necessary the baroque technical matters for prior art pedestrian protecting beam, a kind of pedestrian protecting beam is provided.
A kind of pedestrian protecting beam, comprises integrated injection molding and has U-shaped protection beam main body, multiple U-type groove that described protection beam main body comprises outer wall and is connected with outer wall, and adjacent two U-type groove Opposite direction connections.
Further, the U-type groove between the outer wall of described protection beam main body is two.
Further, reinforced rib is provided with in described U-type groove.
Further, the angle of described reinforced rib and described outer wall vertical direction is 30 ° ~ 45 °.
Further, also comprise covering, described covering is connected with described protection beam main body by the covering mounting bracket being arranged on described protection beam bottom part body.
Further, the cross-sectional plane of described covering mounting bracket is L-type, and the bottom of described covering mounting bracket has covering mounting hole, and covering adopts fastener to be connected by covering mounting hole with the bottom of covering mounting bracket.
Further, described covering mounting bracket is provided with boss, and described fastener is connected with described boss by covering mounting hole.
Preferably, described boss is rhombus.
Preferably, described protection beam main body and described covering mounting bracket one-body molded.
Pedestrian protecting beam of the present utility model, by the structure of the U-type groove of multiple Opposite direction connection, when automobile and pedestrian collision, because structure stress is even, effectively can fall stress concentration, structure is simple simultaneously, is convenient to produce.
Accompanying drawing explanation
Fig. 1 is the integral structure schematic diagram of a kind of pedestrian protecting beam of the utility model;
Fig. 2 is the section drawing of the utility model pedestrian protecting beam;
The covering mounting bracket schematic diagram that Fig. 3 provides for the utility model;
The covering mounting bracket partial enlarged drawing that Fig. 4 provides for the utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
Be illustrated in figure 1 the integral structure schematic diagram of a kind of pedestrian protecting beam of the utility model, comprise:
Integrated injection molding and have U-shaped protection beam main body 1, is illustrated in figure 2 the section drawing of the utility model pedestrian protecting beam, multiple U-type groove that described protection beam main body comprises outer wall 11 and is connected with outer wall, and adjacent two U-type groove Opposite direction connections.
Pedestrian protecting beam of the present utility model, by the structure of the U-type groove of multiple Opposite direction connection, when automobile and pedestrian collision, because structure stress is even, effectively can fall stress concentration, structure is simple simultaneously, is convenient to produce.Meanwhile, pts wt is light, effectively can reduce complete vehicle weight, reduces oil consumption.
Wherein in an embodiment, the U-type groove 12,13 between the outer wall 11 of described protection beam main body 1 is two.
U-type groove can be two or more, as long as adjacent two U-type groove Opposite direction connections, then structure stress just evenly, thus can fall stress concentration effectively.
Wherein in an embodiment, in described U-type groove, be provided with reinforced rib.
The present embodiment is provided with reinforced rib in U-type groove, makes when automobile and pedestrian collision, can provide enough intensity for pedestrian shank protection.
Preferably, the angle of described reinforced rib and described outer wall 11 vertical direction is 30 ° ~ 45 °.
As shown in Figure 3, wherein in an embodiment, pedestrian protecting beam also comprises covering 2, and described covering 2 is connected with described protection beam main body 1 by the covering mounting bracket 3 be arranged on bottom described protection beam main body 1.
The present embodiment is integrated with covering mounting bracket, for covering lower end provides attachment point, saves independent covering mounting support structure.
As shown in Figure 4, wherein in an embodiment, the cross-sectional plane of described covering mounting bracket 3 is L-type, and the bottom of described covering mounting bracket has covering mounting hole 31, and covering adopts fastener to be connected by covering mounting hole with the bottom of covering mounting bracket.
Wherein in an embodiment, described covering mounting bracket 3 is provided with boss 32, described boss 32, and described fastener is connected with described boss 32 by covering mounting hole 31.
By arranging boss structure on covering mounting bracket 3 with the fitting surface of covering 2, the later stage can pass through the installing condition adjusting boss size adjusting covering, and forming process is simple, reduces automobile research cost.
Preferably, described boss 32 is rhombus.
Preferably, described protection beam main body 1 is one-body molded with described covering mounting bracket 3.
Above-mentioned specific embodiment is this practical preferred embodiment just, and the utility model also can have other to be out of shape, such as: the optimization of pair cross-section shape, and the adjustment of covering attachment point position and size.
The above embodiment only have expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
