Description
Technical field
The utility model belongs to body connection structure technical field, and in particular to a kind of car body of aluminum alloy skeleton.
Background technique
With the intensification that the attention of mankind's environmental pollution and energy crisis are realized, the energy resource structure of the entire mankind by
Successive step, automobile industry are also gradually turned to new energy vehicle by conventional fuel oil car therewith, and the purpose that automobile makes the transition to new energy is main
It is the discharge for getting rid of the dependence to traditional energy, reducing energy loss, reducing pollutant.
The transition of automobile industry at this stage is mainly towards electric car direction, and the popularization of electric car is mainly by electricity at present
The influence of pond performance, before the breakthrough that battery performance does not obtain matter, what is mainly faced is as how limited battery capacity is continuous
Increase the course continuation mileage of automobile, the lightweight contribution of automobile should not be underestimated on this problem.
Currently, generally favor comes in the aluminium alloy part of moderate cost, light weight in terms of material for the lightweight of automobile
Traditional steel part is replaced to reach light-weighted purpose, but aluminium alloy weldability is good not as good as steel, weld strength is low, and
It is easy to change the ingredient and mechanical property of former alloy material in high-temperature soldering, it is often broken with cracking, desoldering of welding position etc.
Bad phenomenon；Nowadays more satisfactory aluminium alloy structure connection type has rivets and screw connection.Aluminum alloy materials density is low, bullet
Property modulus it is small, tapping intensity is not high, tapping should not be connected directly on aluminium alloy with screw, therefore by screw connection in a manner of it is normal
The tapping of steel attachment or nut need to be implanted on aluminium alloy part to connect for screw, mode of operation is many and diverse；It is riveted on aluminium alloy
Using relatively broad in the connection of structure, common riveting parts have self-plugging rivet and ring-grooved rivet.Self-plugging rivet applies in general to
In the riveting structure that material thickness is small, riveting intensity demand is low connection；The tension shearing strength of ring-grooved rivet is higher, is suitable for master
The connection of structural member is wanted, riveting material thickness is applied widely.
Currently, for bus body main structure generally select the preferable rectangular pipe fittings of Anti-pull-press, anti-bending strength or other
The pipe fitting of similar closed cavity.Riveting for closed cavity pipe fitting, if strength demand is not high, that self-plugging rivet can be used is directly single
The riveting of sidetracking hole；Select ring-grooved rivet to connect if strength demand is higher, need when connection opposite side hole diameter in connecting side compared with
Big handle hole (being greater than ailhead diameter) is used for drift bolt, and in order to which drift bolt is convenient, the length of rivet need to be longer than structural member cavity depth,
According to the thickness of riveting material, rivet needs to grow very much a part and is pulled off as obsolete material and causes waste of material, in order to protect
Card riveting intensity then needs riveted pipe fitting to have enough wall thickness and increase the quality of structural member, causes vehicle light weight in this way
Change degree is inadequate, if same position pipe fitting two sides require riveting (common connection in body structure) when if can not be applicable in.
The mode of the existing similar cross-section profile riveting of riveting to solve the problems, such as two sides same position, this riveting method two
The connection of part needs two connectors to clamp connection boss to drawing to complete, it is therefore desirable to connector increase and increase vehicle matter
Amount；Since the both ends of riveting profile are solid boss, not only quality is very big, and link position and profiled body Stiffness Distribution are not
Rationally, stress is easy to appear in connection boss and profiled body junction when stress to concentrate, influence structural strength.
For the functional requirement for meeting special part, another bolt connecting mode is also commonly used at present, however, this connection side
Formula is to meet to be bolted required mounting groove, needs to increase aluminium consumption amount, not be consistent with lightweight target.
