Abstract
The invention relates to a reinforced part for an automotive longeron. The main body of the reinforce part is a stamped piece with a U-shaped section; two side walls on the left section of the main body are symmetrically provided with a plurality of guide channels along the height direction; the guide channels are parallelly arranged along the length direction; the right section of the main body is lengthened and designed with a protecting section of a cab; the protecting section is wider than the left section of the main body, and extends to the lower part of the cab in arranging process; the front part and the rear part of the guide channels in the left section of the main body are provided with guide wires; and the guide wires are in oblique crossing with the U-shaped bottom plane of the main body. The reinforced part has the advantage that when automobiles carry out head-on collision, the reinforced part can be sufficiently deformed, so that drivers can keep the prior space unchanged and better protect the safety of passengers.
Description
Technical field
The present invention relates to automotive body structure, be specifically related to a kind of automobile stringpiece reinforcement.
Background technology
At present, automobile longitudinal girder reinforcement commonly used is shorter, and to the protection section of operator's compartment, guide channel is not few, often is 3, and its major defect is, undercapacity, and plastic deformation is big, and frame strength is low, and during head-on crash, the occupant is vulnerable in the operator's compartment.
Summary of the invention
For overcoming the existing in prior technology defective, the invention provides a kind of intensity higher, to the better autobody stringpiece reinforcement of passenger protection.
Autobody stringpiece reinforcement main body of the present invention is that a section is the strip shape blanked part of U-shaped, two sidewall upper edge short transverses in main body left side section are symmetrically arranged with many guide channels, these guide channels parallel are along its length shown, right section lengthening design in main body has operator's compartment protection section, and wideer than main body left side section, extend to under-cab during installation always; Design has guide wire, the U-shaped baseplane oblique of guide wire and main body before and after the guide channel of main body left side section.
Described guide wire be arranged on be subjected to force direction first guide channel before and the most last two guide channels between.
Described guide channel runs through whole sidewall along short transverse.
The equidistant arrangement of described guide channel, on each sidewall at least each 4.
Compared with prior art, automobile of the present invention has following advantage with stringpiece reinforcement:
1, owing to increased operator's compartment protection section, reduces the deflection of operator's compartment, improved the impact strength of car load;
2, because guide channel increases, and guiding groove is designed to run through along short transverse the form of whole sidewall, has increased the deformation distance of Vehicular body front on the one hand, during collision, can absorb more energy, also help distortion on the other hand.
3, the design of guide wire when making the longeron distortion, is carried out regularly.
As seen, when this stringpiece reinforcement carries out head-on crash at automobile, can fully be out of shape, thereby make operator's compartment keep original space invariance, can protect occupant's safety better.

Among the figure, 1-main body left side section, 2-operator's compartment protection section, 3-guide channel, 4-guide wire
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail;
See Fig. 1, Fig. 2 and Fig. 3, the main body of this autobody stringpiece reinforcement is that a section is the strip shape blanked part of U-shaped, two sidewall upper edge short transverses in main body left side section 1 are symmetrically arranged with 8 guide channels 3, these guide channels 3 along its length parallel equidistant from arrangement, and before being subjected to first guide channel of force direction and between the most last two guide channels, guide wire 4 being set, guide wire 4 is angled with the U-shaped baseplane oblique of main body.During frontal crash of vehicles; produce very big energy; 4 pairs of guide channels can absorb more collision energy; guide channel is compressed during collision; produce fully distortion, make most of energy be absorbed herein, and have only sub-fraction energy energy to the body tail transmission; avoid vehicle body to produce very large deformation, the protection vehicle body.Right section lengthening design in main body has operator's compartment protection section 2, and wideer than main body left side section 1, extends to under-cab during installation always; when automobile carries out head-on crash,, can not produce distortion because this section is strongr; thereby make operator's compartment keep original space invariance, protection occupant's safety.
