Description

A kind of vehicle rear pillar

Technical field

The utility model relates to the car body component of vehicle, relates in particular to a kind of vehicle rear pillar.

Background technology

General auto body has three columns, is followed successively by front pillar (A post), center pillar (B post) and rear pillar (C post) from front to back.Rigidity is the index of Automobile Body Design, and because column plays a part the supported cart top cover, so the rigidity of column has determined the integral rigidity of vehicle body to a great extent.Therefore, in the Automobile Body Design process, make column have enough rigidity.CN1316362A discloses a kind of automotive rear pillar, and as shown in Figure 1, this automotive rear pillar comprises inner panel 1, outside plate 2 and brace panel 3, and described inner panel 1 is captiveed joint with outside plate 2 and constituted die cavity 4, and described brace panel 3 is captiveed joint with inner panel 1.Though obtaining part by the rigidity that brace panel 3 is set makes automotive rear pillar, this automotive rear pillar strengthens, but since in the die cavity 4 that inner panel 1 and outside plate 2 constitutes without any being connected and cutting off, and die cavity 4 possesses bigger space, so cause the insufficient rigidity of this automotive rear pillar, thereby when the generation vehicle body bumps, can not prevent the distortion of vehicle body well, thereby can not guarantee passenger's safety effectively, cause the generation of catastrophic failure.

The utility model content

The purpose of this utility model provides a kind of vehicle rear pillar of good rigidity.

The utility model provides a kind of vehicle rear pillar, and this vehicle rear pillar comprises inner panel 1 and outside plate 2, and described inner panel 1 is captiveed joint with outside plate 2 and constituted die cavity 4, and wherein, described inner panel 1 and outside plate 2 have at least one junction in described die cavity 4.

Because the inner panel 1 and the outside plate 2 of the vehicle rear pillar that the utility model provides have at least one junction in described die cavity 4, so the space of die cavity 4 is cut off, thereby improved the rigidity of vehicle rear pillar, so the vehicle rear pillar that the utility model provides is the support vehicle top cover more stably, and when the vehicle body collision takes place, the distortion of vehicle body can be prevented well, thereby passenger's safety, the generation of the incidents that averts a calamity can be guaranteed effectively.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further described.

To shown in Figure 5, the vehicle rear pillar that the utility model provides comprises inner panel 1 and outside plate 2 as Fig. 2, and described inner panel 1 is captiveed joint with outside plate 2 and constituted die cavity 4, and wherein, described inner panel 1 and outside plate 2 have at least one junction in described die cavity 4.

Described junction can take any-mode to form between inner panel 1 and outside plate 2, and the junction can be connected to form by the contact of inner panel 1 and outside plate 2 as described, also can form by other parts.

When inner panel 1 and outside plate 2 directly carry out contact when being connected, can form a contact, line contact or face contact between inner panel 1 and the outside plate 2.Normally, adopt the mode of welding well known in the art to carry out the contact connection between inner panel 1 and the outside plate 2.In order to simplify connection procedure and further to improve the rigidity of vehicle rear pillar, extremely shown in Figure 5 as Fig. 3, preferably, described inner panel 1 contacts at the die cavity 4 inner lines that form with outside plate 2, and the contact wire 7 between inner panel 1 and the outside plate 2 is divided into a plurality of subtypes chamber 6 with die cavity 4, and more preferably, described contact wire 7 is parallel to the longitudinal axis of die cavity 4, described longitudinal axis is meant when rear pillar is installed on the automobile, the axis of die cavity 4 on the bodywork height direction.Be connected in order to make inner panel 1 form contact with outside plate 2, can make inner panel 1 and/or outside plate 2 to die cavity 4 inner protrusions, the inner panel 1 of described protrusion and/or outside plate 2 can further improve the rigidity of vehicle rear pillar.To shown in Figure 5, described outside plate 2 is to die cavity 4 inner protrusions as Fig. 3.

As shown in Figure 6, the vehicle rear pillar that the utility model provides can also comprise connecting panel 5, described inner panel 1 is connected by connecting panel 5 in die cavity 4 inside with outside plate 2, captive joint with outside plate 2 with inner panel 1 respectively in the both sides of described connecting panel 5, described connecting panel 5 can be provided with arbitrarily in die cavity 4 inside, and die cavity 4 is divided into a plurality of subtypes chamber 6.In order further to improve the rigidity of rear pillar, preferably, described connecting panel 5 is parallel to the longitudinal axis setting of die cavity 4, and described longitudinal axis is meant when rear pillar is installed on the automobile, the axis of die cavity 4 on the bodywork height direction.Described connecting panel 5 can be captiveed joint with outside plate 2 with inner panel 1 by variety of way well known in the art, as adopting the mode of the normally used welding of those skilled in the art.

Described inner panel 1 can be connected at die cavity 4 inner formation 1 place with outside plate 2 or many places connect, and determines as the case may be.

The volume in a plurality of subtypes chamber 6 of formation can equate in the described die cavity 4, also can be unequal, and in order to improve the integral rigidity of vehicle rear pillar, preferably, the ratio of any two volume is 1 in described a plurality of subtypes chamber 6: 1-1: 5.

In order further to strengthen the rigidity of this vehicle rear pillar, as Fig. 2 and shown in Figure 5, preferably, this vehicle rear pillar also comprises brace panel 3, and described brace panel 3 is arranged in die cavity 4 and captives joint with inner panel 1 or outside plate 2.Described brace panel 3 adopts the mode of welding to captive joint with inner panel 1 or outside plate 2 usually.Normally, brace panel 3 is captiveed joint with inner panel 1.As shown in Figure 5, be provided with under the situation of brace panel 3 in die cavity 4 inside, inner panel 1 can form at brace panel 3 places with outside plate 2 and be connected.

Described inner panel 1 can be formed by a slab integral, also can be made of the polylith plate, determines as the case may be.Described outside plate 2 can be formed by a slab integral, also can be made of the polylith plate, determines as the case may be.Described polylith plate is the mode captive joint by welding usually.Described inner panel 1 adopts the mode of welding to captive joint with outside plate 2 usually, thereby constitutes die cavity 4.

Extremely shown in Figure 5 as Fig. 2, described inner panel 1 is welded by first inner panel 8 and second inner panel 9, and outside plate 2 is welded by first outside plate 10 and second outside plate 11, and described first outside plate 10 has projective structure, brace panel 3 is welded on the top of inner panel 1, with first inner panel 8 and second inner panel, 9 weld togethers.When inner panel 1 is connected with outside plate 2, with the front end 2A of outside plate 2, back right-hand member 2B, upper end 2C and lower end 2D respectively with front end 1A, back right-hand member 1B, upper end 1C and the lower end 1D weld together of inner panel 1, so just formed die cavity 4.Because first outside plate 10 has projective structure, contact so first outside plate 10 forms line with inner panel 1, in this contact position with first outside plate 10 and inner panel 1 weld together, thereby die cavity 4 is divided into two sub-die cavities 6.

There is no particular limitation to the shape of inner panel 1, outside plate 2, brace panel 3 and connecting panel 5, can determine as the case may be.In order to improve the rigidity of vehicle rear pillar, preferably, described inner panel 1, outside plate 2 and brace panel 3 are rough plates.

The vehicle rear pillar that the utility model provides is owing to connect and cut off die cavity 4 inner formation, so that the rigidity of whole vehicle rear pillar strengthened, thereby support vehicle top cover more stably, and when bump takes place in vehicle body, can prevent the distortion of vehicle body well, thereby can guarantee passenger's safety effectively, the generation of the incidents that averts a calamity.
