Abstract
The invention relates to a coach side wall frame structure with an emergency door frame and a coach. The coach side wall frame structure comprises a compartment door upper stringer, a compartment door lower stringer, a side window upper stringer and a side window lower stringer, which all extend horizontally; the coach side wall frame structure further comprises compartment door pillars, middle beam pillars, an emergency door upper stringer and an emergency door lower stringer, and emergency door front pillars and emergency door rear pillars. The mounted emergency door frame destroys the frame structure of the original coach bodywork, thus the upper and lower ends of the emergency door front pillars and the emergency door rear pillars are fixedly connected with the side window upper stringer and the compartment door upper stringer, respectively, and the emergency door lower stringer is fixedly connected to the compartment door upper stringer by bonding welding, so as to compensate for the strength and stiffness losses caused by the discontinuity of the side window lower stringer to the frame structure. By using such reasonable design, the coach side wall frame structure with the emergency door frame and the coach are provided, thus sufficient space of the emergency door is allowed, and reduction in the strength and stiffness of the original frame structure is avoided.

Accompanying drawing explanation
Fig. 1 is the structural representation of an embodiment of a kind of passenger vehicle side wall frame structure with emergency door doorframe of the present invention;
Fig. 2 is that A in Fig. 1 is to cutaway view.
Detailed description of the invention
A kind of structural representation of an embodiment of the passenger vehicle side wall frame structure with emergency door doorframe as illustrated in fig. 1 and 2, comprise length to extend along the longitudinal direction and longeron 11 under longeron 10, hatch door on longeron 5, hatch door under longeron 2, side window on the side window be arranged in juxtaposition up and down, also include waist rail column 7, hatch door column 13 and side window pillar 1.On side window, on longeron 2 and hatch door, longeron 10 all adopts logical root longeron, strengthen the intensity of skeleton, under side window, longeron 5 is separated by emergency door doorframe structure, on side window, under longeron 2 and corresponding side window, longeron 5 to be connected welding by side window pillar 1 and emergency door column 3, side window pillar 1 carries out welding through the upper surface that longeron 5 under side window extends to longeron 10 on hatch door and is connected, and adds the intensity of skeleton.
In order to ensure that emergency door has enough large space, longeron 2 and hatch door are provided with an emergency door doorframe structure between longeron 10 to the side window of Bus Frame structure, this emergency door doorframe structure to comprise on emergency door longeron 12, emergency door column 3 under longeron 8, emergency door, and emergency door column 3 comprises emergency door A-pillar 3-1 and emergency door rear column 3-2.Under side window, longeron 5 disconnects at emergency door doorframe place and is divided into two sections, front and back, in order to avoid reducing the strength and stiffness of skeleton, emergency door column 3 and the upper and lower longeron of emergency door is adopted to carry out the transmission of power, concrete mode is, on emergency door, the front/rear end of longeron 8 carries out being connected welding with two sides of emergency door column 3 respectively, the upper surface of emergency door column 3 is welded with the lower plane of longeron on side window 2, the upper plane-welding of longeron 12 under the lower surface of emergency door column 3 and emergency door, under emergency door longeron 12 with and hatch door on longeron 10 fit and weld, this ensure that the bulk strength of emergency door doorframe structure, due to longeron under side window 5 separate by emergency door doorframe and can not use logical root longeron, under the side window adopting emergency door column place to disconnect, the end of longeron 5 is welded with corresponding emergency door column 3 and is connected, compensate for the intensity that longeron 5 under side window can not use logical root longeron to lose further.Under emergency door, fit with the side of waist rail column 7 and weld in longeron 12 front and rear end, emergency door square frame after assembly welding keeps concordant at direction plane inside vehicle body, under emergency door, longeron 12 size crosses over column before and after emergency door, and length extends to a previous or rear hatch door column 13.Longeron 8 and side window exist gap, welding thin-walled steel plate and backing plate 4 in gap between longeron 2 to emergency door, and backing plate 4 is fitted with the section bar of surrounding respectively and is welded.In other embodiments of the invention, according to actual conditions, on emergency door, longeron 8 and longeron 2 on side window also can also connect in solid welding, there is not gap therebetween.
On hatch door, longeron 10 leads to root longeron for fore-and-aft direction, under hatch door, longeron 11 is fixed on longeron 10 on hatch door by hatch door column 13 welding, hatch door column 13 welds around extending out to longeron on hatch door 10 medial surface to fit with the waist rail column 7 of relevant position or emergency door column 3, ensure the globality of skeleton, improve the strength and stiffness of skeleton.
Emergency door column 3, be two rectangle pipe materials and weld to form, in order to improve the intensity of emergency door doorframe skeleton structure further, under side window, longeron 5 and hatch door are fixed with waist rail column 7 and oblique section bar 6 between longeron 10, and longeron 5 is provided with waist rail column 7 or emergency door column 3 place of being connected and strengthens angle 9 under side window.Emergency door A-pillar 3-1 and longeron under side window 5, waist rail column 7 and strengthen angle 9 and be connected and weld, emergency door rear column 3-2 respectively with longeron under side window 5, strengthen angle 9 and the oblique section bar 6 between waist rail and be connected and weld.
Emergency door column 3 also can be also welded by square pipe to form in other embodiments of the invention, and quantity can adjust according to actual needs; Under side window, longeron 5 and hatch door also can not arrange waist rail column 7 between longeron 10, all replace waist rail column 7 with emergency door column 3, also before and after emergency door, waist rail column 7 can be provided with in column place.
In other embodiments of the invention, above-described attachment, except adopting welding manner, can also adopt other modes such as riveted joint.
The embodiment of a kind of passenger vehicle of the present invention, the side wall frame structure that passenger vehicle comprises is identical with the skeleton structure in described passenger vehicle side wall frame structure specific embodiment, repeats no more herein.
The present invention, by above appropriate design emergency door doorframe structure, provides a kind of body side wall skeleton structure with emergency door doorframe and passenger vehicle, both ensure that emergency door had enough large space, and reduced again the strength and stiffness of former body framwork not significantly.
