Description
Technical field
Field is manufactured the utility model relates to integral new-energy passenger and its parts, it is more specifically a kind of
The Bus Roof Outer Panels structure that aluminium alloy and galvanized steel plain sheet are used in mixed way.
Background technology
In today that integral new-energy passenger industry rapidly develops, kerb weight greatly affects energy consumption of vehicles and battery durable
Mileage, the lightweight of vehicle body are always the important topic of major automobile vendor's research, and aluminum-steel hybrid vehicle body is intended to from cost, assembling
Difficulty, effect three's clock take an equalization point.According to the loss of weight data analysis of all-aluminium body, the weight loss effect of head cover lead-covering is most bright
It is aobvious, by taking 10 meters of cars as an example, zinc (is crossed by Dzn）Covering changes aluminum alloy outer cover about loss of weight 120kg into, compares Dzn covering losss of weight
60%, account for about the 1/3 of entire all-aluminium body loss of weight, and in terms of manufacture and assembling, the application of lead-covering is simpler than aluminium skeleton
It is much easier, and on the manufacture abortive lot of vehicle without influence, tooling device is also required without newly-increased.
So on the basis of vehicle is steel skeleton, the aluminum alloy outer cover structure used on a kind of head cover is provided, it is desirable that right
The structure and manufacture craft of raw steel skeleton do not generate excessive change, you can are mitigated again with reaching drop, and facilitate roof skin solid
The purpose of Dingan County's dress.
Utility model content
Disclosed by the utility model is the Bus Roof Outer Panels structure that a kind of aluminium alloy and galvanized steel plain sheet are used in mixed way, master
Aim to overcome that deficiencies of the prior art and disadvantage.
The technical solution adopted in the utility model is as follows：
The Bus Roof Outer Panels structure that a kind of aluminium alloy and galvanized steel plain sheet are used in mixed way includes that the side top of roll-forming is covered
Covering is pushed up at skin and middle part, and the both sides of side top covering are adapted fitting, and its outside portion with the radian at bus roof outer both ends
It is fixed on the steel skeleton of bus roof outer by welding manner, inside portion and the middle part top covering of side top covering are overlapped in
The upper plane of a longeron outside bus roof outer flash trimming longeron, and be fixedly installed by rivet, rivet sequentially passes through middle part
Push up the upper plane of covering, side top covering and overlapped longeron；The boundary of the side top covering and middle part top covering was all covered
Should overlapped longeron, described overlapped that longeron is steel pipe skeleton, penetrates through from front to back, allows to punish section in head cover arc bar, allow
A small number of locals are without this beam caused by structure limits.
Further, side top covering is installed with the reinforcing rib of perforation setting at overlapped longeron.
Further, the reinforcing rib is in the structure setting that raises up, the width of height of projection 5mm, reinforcing rib
50mm。
Further, the reinforcing rib pushes up the fixed installation slot of the one heavy platform structure of edge formation of covering, institute to side
The left and right both ends cooperation for stating middle part top covering is installed on the fixed installation slot.
Further, also cooperation is filled with joint sealant on the fixed installation slot.
By the above-mentioned description to the utility model it is found that compared to the prior art, the utility model has the advantage of：
The utility model provides the aluminum alloy outer cover structure used on a kind of head cover, the structure to raw steel skeleton and making
Technique does not generate excessive change, you can the purpose for being mitigated again with reaching drop, and roof skin being facilitated to be fixedly mounted, this practicality are new
Zinc-plated top covering of the type in both sides is having one to penetrate through front and back reinforcing rib close at overlap joint longeron, and the reinforcing rib to side pushes up illiteracy
The heavy platform that skin edge is formed can be used as the fixed installation slot of middle part top covering left and right ends, convenient to supplement bonded adhesives in this slot
And fluid sealant, play the role of protecting colloid and waterproof, after covering fixation is pushed up at middle part, covering transition is pushed up without scale, no with side
Easy ponding, simple and beautiful, and easy processing make, versatile.

Fig. 2 is the partial enlargement structural representation of part A in Fig. 1.
Fig. 3 is the structural schematic diagram of the utility model side top covering and middle part top covering.
Specific implementation mode
Illustrate with reference to the accompanying drawings to further explain specific embodiment of the present utility model.
As shown in Figure 1, Figure 2 and Figure 3, the Bus Roof Outer Panels structure that a kind of aluminium alloy and galvanized steel plain sheet are used in mixed way, packet
Include the side top covering 1 and middle part top covering 2 of roll-forming, the arc of the both sides and bus roof outer both ends of side top covering 1
Degree is adapted fitting, and its outside portion is fixed on by welding manner on the steel skeleton of bus roof outer, side top covering 1
Inside portion is overlapped in the upper plane of a longeron 3 outside bus roof outer flash trimming longeron with middle part top covering 2, and passes through 4 riveting of rivet
Connect fixed setting, rivet 4 sequentially passes through the upper plane of middle part top covering 2, side top covering 1 and overlapped longeron 3；The side
The boundary of top covering 1 and middle part top covering 2 all covered should overlapped longeron 3, it is described that overlapped that longeron 3 is steel pipe skeleton, the past
To rear perforation, allow to punish section in head cover arc bar, allows a small number of locals caused by structure limits without this beam.
Further, side top covering 1 is installed with the reinforcing rib 5 of perforation setting at overlapped longeron 3.
Further, the reinforcing rib 5 is in the structure setting that raises up, the width of height of projection 5mm, reinforcing rib
