Abstract
The utility model relates to the field of an automobile structure, and particularly discloses an energy absorbing front carling of a car frame. The surface of the front carling is corrugate. The surface of the front carling is provided with protrusions and grooves, and corresponding wave crests and wave troughs of corrugations are formed. The protrusions and grooves are arranged along the length direction of the front carling in sequence. According to the energy absorbing front carling of the car frame, surfaces of a left front carling and a right front carling of an automobile are provided with the corrugations which are capable of absorbing impact energy when impact of the automobile occurs, amount of deformation of an automobile body is controlled, the deformation and impact kinetic energy are enabled to be balanced, integrality of a passenger compartment is kept, and the automobile structure is prevented from deforming, intruding into the passenger compartment and injuring passengers.
Description
Technical field
The utility model relates to the vehicle structure field, relates in particular to a kind of energy-absorbing vehicle frame front side member.
Background technology
Present development along with auto-industry; the recoverable amount of automobile is increasing; the generation quantity of safety misadventure is also in continuous increase; the vehicle structure distortion is invaded the crew module and is directly injured the occupant during collision; so; need to carry out safe design and various protective devices are set vehicle structure, these measures can play a role when accident occurs, reach to reduce as much as possible the degree that occupant on the car and goers outside vehicle come to harm.
Existing vehicle frame left and right sides front side member is trench structure, and rigidity is strong, can not carry out energy absorbing during collision, and the concussion damage that vehicle is subject to is just more serious.
The utility model content
The technical matters that (one) will solve
The purpose of this utility model is, a kind of bellows-type energy-absorbing vehicle frame front side member is provided, and the energy that is produced when absorbing collision happens is controlled the body distortion amount simultaneously.
(2) technical scheme
In order to solve the problems of the technologies described above, the utility model provides a kind of energy-absorbing vehicle frame front side member, and the surface of described front side member is corrugated, has projection and groove on its surface, corresponding crest and the trough that forms ripple, described projection and groove are arranged successively along the front side member length direction.
Preferably, the distance between adjacent two projections or two grooves is the pitch of waves, and the described pitch of waves is 5mm-7mm.
Preferably, described front side member is tubulose or tabular.
Preferably, when described front side member was tubulose, its cross-sectional plane was annular.
Preferably, the cross-sectional plane of described front side member is annular arrangement.
Preferably, when described front side member was tabular, its cross-sectional plane was rectangle.
Preferably, the wall thickness of described bellows is 3mm-8mm.
(3) beneficial effect
The utility model all is set to corrugated by the surface with the left and right vehicle wheel front side member, can be when collision happens, absorb collision energy, control body distortion amount, distortion and impact kinetic energy are balanced each other, the integraty that keeps the crew module, the vehicle structure distortion is invaded the crew module and is directly injured the occupant when preventing from colliding.
Description of drawings
Fig. 1 is the structural representation of embodiment of the invention energy-absorbing vehicle frame front side member.
The specific embodiment
Below in conjunction with drawings and Examples embodiment of the present utility model is described in further detail.Following examples are used for explanation the utility model, but can not be used for limiting scope of the present utility model.
As shown in Figure 1, the energy-absorbing vehicle frame front side member of present embodiment, its surface is corrugated, has projection and groove on its surface, corresponding crest and the trough that forms ripple, described projection and groove are arranged successively along the front side member length direction.Described front side member is tubulose or tabular, and when it was tubulose, its cross-sectional plane was the annular of annular arrangement or the sealing such as three-back-shaped, and at this moment, the structure of described front side member is bellows structure; When its when being tabular, its cross-sectional plane is rectangle etc.When collision happens, described energy-absorbing vehicle frame front side member can absorb collision energy, and control body distortion amount balances each other distortion and impact kinetic energy, keeps crew module's integraty, and the vehicle structure distortion is invaded the crew module and directly injured the occupant when preventing from colliding.
Between two projections that above-mentioned bellows is adjacent or two grooves is the pitch of waves apart from a, and its Numerical Control (NC) is in the 5mm-7mm scope, because when the pitch of waves is too small, its energy absorption ability can be protected, but controls a little less than the ability of deflection; When the pitch of waves was excessive, the ability of its control deflection can be protected, but a little less than its energy absorption ability.
The wall thickness of above-mentioned bellows is controlled in the 3mm-8mm scope, because the too small meeting of thickness makes the front side member remitted its fury, the excessive weight of longeron that can make again of thickness increases.
The material of the energy-absorbing vehicle frame front side member of present embodiment can be this areas such as steel, iron or its alloy longeron material commonly used.
Embodiment of the present utility model provides for example with for the purpose of describing, and is not exhaustively or with the utility model to be limited to disclosed form.Many modifications and variations are apparent for the ordinary skill in the art.Selecting and describing embodiment is for better explanation principle of the present utility model and practical application, thereby and makes those of ordinary skill in the art can understand the various embodiment with various modifications that the utility model design is suitable for special-purpose.
Claims (7)
