The specific embodiment
In order to make those skilled in the art person understand better the scheme of the utility model embodiment, below in conjunction with drawings and embodiments, the utility model embodiment is described in further detail.
Simple in structure for car rear in prior art; crashproof intensity difference; can't effectively protect the problem of vehicle body; the utility model provides a kind of car rear; this car rear by changing vertical supporting shape and be provided with horizontal guardrail brace panel; make the crashproof intensity of described car rear stronger, can actv. protection automobile body when bumping.
Fig. 2 is the structural representation of the utility model car rear.
Car rear in the utility model comprises: laterally guardrail 5 reaches at least two vertical supportings 8; One end of described vertical supporting 8 is fixed on described horizontal guardrail 5, and the other end is fixed on the chassis side rail of automobile tail.
Described horizontal guardrail 5 is used for automobile tail is protected, and when the afterbody of described automobile is subject to clashing into, at first strikes horizontal guardrail 5, and described horizontal guardrail 5 relies on the profile of self and intensity to provide the actv. protection to automobile tail.
Described horizontal guardrail 5 is on the basis that guarantees sufficient intensity, also want its weight of reduce, described horizontal guardrail 5 can be rectangular tubular for this reason, the large and inner hollow of the crashproof intensity of described tubulose, like this on the basis that guarantees its crashproof intensity, reduce again weight, be conducive to the installation and removal of described horizontal guardrail 5, be applicable to the protection to full-sized car.
In order further to strengthen the crashproof intensity of described car rear, can be provided with the horizontal guardrail brace panel 6 suitable with its outline in described horizontal guardrail middle part, vertical supporting 8 is connected on described horizontal guardrail brace panel 6.Described horizontal guardrail brace panel 6 is arranged on the middle part of horizontal guardrail 5, has further strengthened again the crashproof intensity of described horizontal guardrail 5 middle parts, and when it bumped, actv. had prevented from boring the generation of hitting phenomenon, has better protected car body.
In order to provide enough bearing forces to the car rear, be provided with vertical supporting 8 on described horizontal guardrail, be used for to support the fixed lateral guardrail, make described horizontal guardrail 5 can keep shape when bumping, to impact resistance, so that vehicle body is protected.
One end of vertical supporting 8 connects horizontal guardrail 5, and the other end is connected on the chassis side rail of tail of body.Can be provided with for both sides the straight plate of bending edges at described vertical supporting 8 like this, be used for the described horizontal guardrail 5 of fixed pedestal.In order further to improve its support strength, the vertical supporting closure plate is set on the bending edges of described vertical supporting sidewall, makes described vertical supporting and vertical supporting closure plate enclose rectangular tubular, so both guaranteed support strength, alleviate again weight of equipment, be conducive to the I﹠M of equipment.
