Abstract
The utility model discloses a side wall structure of an urban rail train, which comprises an outermost covering, a covering reinforcing board, a covering support board, doorway vertical posts and window vertical posts. The covering reinforcing board and the outer covering are attached to each other and fixedly welded, the edges of the covering support board and the covering reinforcing board are lapped and fixedly welded, the middle of the covering support board and the outer covering are attached to each other and fixedly welded, the outer sides of the doorway vertical posts are mutually attached to the covering reinforcing board and fixedly welded, and the outer sides of the window vertical posts are mutually attached to the outer covering and fixedly welded. A first mounting step matched with the covering reinforcing board is arranged on the covering support board, and a second mounting step matched with turned edges of the doorway vertical posts is also arranged on the covering support board. The side wall structure is light in weight, more attractive, higher in strength, and applicable to urban rail trains highly requiring on train body structural strength.
Description
Technical field
The utility model relates to carbody structure field, relates in particular to a kind of municipal rail train sidewall structure.
Background technology
The current track vehicle extensively enters urban life, and in the majority with the corrosion-resistant steel vehicle, and the body construction of municipal rail train partly is made of ceiling, underframe, headwall and side wall etc., and side wall is provided with the car door of window and passenger getting on/off.The side wall of municipal rail train at present adopts electronic built-in.In order to improve the safe reliability of municipal rail train side door folding, side door is upgraded to Electric plug sliding door by electronic built-in door gradually, and Electric plug sliding door is heavier than electronic built-in mechanism, and complex structure, mounting condition are slightly high, and this just needs sidewall structure firmer.
Existing sidewall structure roughly comprises side wall column, covering stay bearing plate, exterior skin.In order further to increase intensity, behind the covering stay bearing plate, increase the structure that covering is mended plate, but the covering stay bearing plate is not connected on the window column, causes a little less than the plot structure intensity relative thin, door district steel structure is stable inadequately.Municipal rail train is also very high to the body of wall appearance requirement simultaneously, and is provided with the blank window structure, has restricted the thickness of body of wall.Therefore when satisfying visual effect, improve vehicle intensity and keep light-weight design just to become difficult point.
The utility model content
The technical matters that the utility model solved provides in attractive in appearance and weight-saving prerequisite and makes the higher municipal rail train sidewall structure of side wall intensity.
The technical solution adopted in the utility model is, the municipal rail train sidewall structure, comprise outermost exterior skin, covering is mended plate, the covering stay bearing plate, doorway column and window column, covering benefit plate and exterior skin fit and weld fixing, the covering stay bearing plate overlaps mutually with covering benefit panel edges and welds fixing, covering stay bearing plate middle part fits with exterior skin and welds fixing, described covering stay bearing plate two ends are also fixing with doorway column and the welding of window column, the described doorway column outside and covering are mended plate and are fitted and weld fixingly, and the described window column outside fits with exterior skin and welds fixing.
For covering stay bearing plate and doorway column and window column are better fitted, it is capable that described doorway column cross-section is opening U word toward the outer side, and be folded into 90 ° flange to both sides in port, the covering stay bearing plate is provided with covering and mends the first suitable assembling step of plate, be provided with the second assembling step suitable with the flange of doorway column simultaneously, the first assembling step and the second assembling step are one time punching molded.
Described exterior skin and covering are mended and are spot welding between plate, covering stay bearing plate, doorway column and the window column and are connected.
As preferably, described dot weld nugget diameter is 4.5mm to 6.1mm.
Described covering stay bearing plate thickness is 1.5mm, and it is 1.5mm that described covering is mended plate thickness.
The beneficial effects of the utility model are the intensity that has effectively increased side wall, reach the Electric plug sliding door desirable strength, the thickness that the part has increased side wall improves the car body planeness, avoid the too much weightening finish of tare, it is that independent processing is welded in body of wall then that covering stay bearing plate and covering are mended plate, dimensional accuracy height, good manufacturability.

Be labeled as among the figure: the 1-exterior skin, the 2-covering is mended plate, 3-covering stay bearing plate, the 31-first assembling step, the 32-second assembling step, 4-doorway column, 5-window column.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1, municipal rail train sidewall structure of the present utility model, doorway column 4 places, structure from outside to inside is that exterior skin 1, covering are mended plate 2, covering stay bearing plate 3 and doorway column 4, fixes with spot welding between them; Window column 5 places do not establish covering and mend plate 2, can alleviate car body weight so as far as possible, and exterior skin 1 fits with window column 5 and spot welding is fixed; Covering is mended plate 2 width greater than doorway column 4, and covering stay bearing plate 3 overlaps mutually with covering benefit plate 2 edges and spot welding is fixed; Covering stay bearing plate 3 middle parts and exterior skin 1 fit and spot weld is fixed.Described covering stay bearing plate 3 two ends also extend to doorway column 4 and window column 5 places simultaneously, and spot welding is fixed mutually.Effective like this structural strength that increases the door district can satisfy the requirement of changeing the moving stopping sliding door of distribution, also makes car side exterior skin 1 outward appearance more smooth simultaneously, and visual effect is better.
For covering stay bearing plate 3 and doorway column 4 and window column 5 are better fitted, described covering stay bearing plate 3 is provided with the two stratotypes rank of presenting a theatrical performance as the last item on a programme, and the flange of mending the edge of plate 2 and doorway column 4 respectively at covering is suitable.Wherein the first assembling step 31 is suitable with covering benefit plate 2, and the second assembling step 32 is suitable with the flange of doorway column 4.The first assembling step 31 and the second assembling step 32 are one time punching molded.
Described exterior skin 1 and covering are mended and are electric welding between plate 2, covering stay bearing plate 3, doorway column 4 and the window column 5 and are connected.As preferably, described dot weld nugget diameter is 4.5mm to 6.1mm.Described covering stay bearing plate 3 thickness are 1.5mm, and it is 1.5mm that described covering is mended plate 2 thickness.
