Abstract
The utility model relates to a safe and firm reinforcement structure of vehicle front pillar with simple structure, belongs to the technical field of machinery and solves the problem that the strength of the existing vehicle front pillar is not enough. The improved reinforcement structure of vehicle front pillar comprises a front pillar outside plate and a front pillar inside plate, and is characterized in that a reinforcement plate is arranged between the front pillar outside plate and the front pillar inside plate, the reinforcement plate and the front pillar inside plate forms a bigger cavity, because the section area of an affordable load is increased, the updated structure can bear the bigger positive load than the existing structure, the intrusion quantity of the front pillar is reduced in a head-on crash, the living space of the passenger can be better ensured, and the optimization method considers the requirements of process, manufacture and the like. The reinforcement structure of vehicle front pillar has simple structure and convenient process.
Description
Technical field
The utility model belongs to field of mechanical technique, relates to the additional strengthening of a kind of automotive front pillar, particularly a kind of automotive front pillar.
Background technology
Modern economy develops rapidly, living standards of the people are greatly improved, and automobile has entered huge numbers of families as a kind of important vehicle, and the safety performance of automobile also receives publicity day by day, and many up-to-date technologys are used to prevent injure taking advantage of circle to produce behind the vehicle collision.The good job of safety performance has become a major criterion weighing the automobile quality, wherein, strengthens the vehicle body crashworthiness, and body distortion is a key index that improves the vehicle passive safety performance to occupant's injury behind the crash-avoidance.
Vehicle causes the injury to chaufeur and passenger easily in offset collision, thereby for the safety of the front pillar of vehicle exacting requirements is arranged.In the prior art, since the strength of material of the side-wall outer-plate that adopts on the front pillar of automobile generally a little less than, front pillar inner panel epimere plate brace panel material is generally high tensile steel plate, mainly be that front pillar outside plate and front pillar inner panel bear head-on crash load in the collision, but since the ability of its bearing load a little less than, the intrusion amount of front pillar is bigger in collision, and occupant's living space reduces, and chaufeur in the collision and occupant exist bigger risk.
Summary of the invention
The purpose of this utility model is to have the problems referred to above at existing technology, has proposed a kind of additional strengthening of simple in structure, the firm automotive front pillar of safety.
The purpose of this utility model can realize by following technical proposal: a kind of additional strengthening of automotive front pillar, comprise front pillar outside plate, front pillar inner panel, it is characterized in that, be provided with a brace panel between front pillar outside plate and the front pillar inner panel, form a crashproof chamber between this brace panel and the front pillar inner panel.
The technical program is optimized preceding rod structure, by a brace panel is set in outside plate and front pillar inner panel, forms a crash-proof cavity body structure in the inside of front pillar, and its section structure is changed, but has increased bearing load amount in the collision.
In the additional strengthening of above-mentioned a kind of automotive front pillar, described brace panel is to front pillar outside plate direction projection.In the technical program, brace panel is to front pillar outside plate direction projection, and the crashproof cavity volume that forms between itself and the front pillar inner panel is further increased, and can bear bigger load, strengthens crashproof effect.
In the additional strengthening of above-mentioned a kind of automotive front pillar, described brace panel is fixed on the joint portion of front pillar inner panel and front pillar outside plate.In the technical program brace panel, front pillar inner panel, front pillar outside plate three's edge stacked together and fixed, make structure compact more, firmly.
In the additional strengthening of above-mentioned a kind of automotive front pillar, described brace panel and front pillar inner panel and front pillar outside plate are fixing by welding.
In the additional strengthening of above-mentioned a kind of automotive front pillar, described brace panel and front pillar inner panel and front pillar outside plate are fixed by fastener.
In the additional strengthening of above-mentioned a kind of automotive front pillar, described brace panel is the integrative-structure that steel plate is made.
In the additional strengthening of above-mentioned a kind of automotive front pillar, described brace panel is provided with reinforced rib.By reinforced rib is set, can strengthen the crashworthiness of brace panel in the technical program.
Compared with prior art, the technical program is by optimizing the front pillar inner structure, brace panel is set, make to form bigger cavity between itself and the front pillar inner panel, but because the cross-sectional area of bearing load increases, the texture ratio existing structure after the renewal can bear bigger forward load, reduce the intrusion amount of front pillar in the head-on crash, guarantee occupant's living space better, and this optimization method taken into full account the requirement of aspects such as technology, making, it is simple in structure, technology is easy.
Description of drawings
Fig. 1 is the utility model middle section structural representation.
Fig. 2 is the structural representation of brace panel 3 in the utility model.
Among the figure, 1, the front pillar inner panel; 2, front pillar outside plate; 3, brace panel; 31, reinforced rib; 4, crashproof chamber.
The specific embodiment
Below be specific embodiment of the utility model and in conjunction with the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.
With reference to accompanying drawing, the brace panel 3 that present embodiment adopts is a bar shaped reinforcement that is formed by the high tensile steel plate integrated punching.Present embodiment is installed in brace panel 3 on the joint portion of front pillar inner panel 1 and front pillar outside plate 2, and the two ends that are about to brace panel 3 are clipped between front pillar inner panel 1 and the front pillar outside plate 2, and are fixing by welding, and makes to form crashproof chamber 4 between brace panel 3 and the front pillar inner panel 1.Brace panel 3 is to front pillar outside plate 2 direction projectioies, and the structure of its cross section structure and front pillar outside plate 2 roughly is complementary, and can enlarge the space in the crashproof chamber 4 to greatest extent, to strengthen the load that can bear.Brace panel 3 can reach 46mm with the maximum spacing place of front pillar inner panel 1 in the present embodiment.
Specific embodiment described herein only is that the utility model spirit is made casehistory.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
Although this paper has used terms such as front pillar inner panel 1, front pillar outside plate 2, brace panel 3, reinforced rib 31, crashproof chamber 4 morely, do not get rid of the possibility of using other term.Using these terms only is in order to describe and explain essence of the present utility model more easily; They are construed to any additional restriction all is contrary with the utility model spirit.
