Abstract
The invention discloses a method and a structure for preventing impact on a weak part of a vehicle body shell based on the light weight of the vehicle body shell. A truss structure is taken as a framework, the vehicle body shell consisting of plates is connected with the truss structure framework, and the weak part of the vehicle body shell is arranged at the position of a framework beam forming the truss structure. The truss structure is skillfully combined with the vehicle body shell, and the framework beam of the truss structure reinforces the weak part of the vehicle body shell to prevent the impact, so that on the one hand, the problem of preventing the impact on the weak part of the vehicle body shell is solved, and on the other hand, by connecting the truss structure with the vehicle body shell, the using amount of plate materials and the weight of the vehicle body shell are reduced on the premise of ensuring the strength of a vehicle body, and a basis is provided for reducing the mass center of a vehicle; and the light weight of the vehicle body shell is realized.
Description
Technical field
The invention belongs to automotive technology, be specifically related to a kind of safety method of auto body protecting against shock.
Background technology
Existing bodyshell all is put together by the plate welding.The method of the protecting against shock of this bodyshell is to adopt double-deck plate, the setting of staggering of the weak soldered of outer plate and the weak soldered of internal layer plate, and the while is provided with the filling energy-absorbing material between two-layer plate.This structure can prevent external impact by actv., protection passenger's safety.But this structure makes body quality big, thereby brings the barycenter height of car load that the oil consumption of vehicle is big first, second influences vehicle run stability because the plate material usage is big.
Summary of the invention
The object of the present invention is to provide a kind of method and structure thereof, to address the above problem based on bodyshell lightweight solution bodyshell weak part protecting against shock.
The method that solves bodyshell weak part protecting against shock based on the bodyshell lightweight of the present invention, it is to be skeleton with the truss structure, the bodyshell that is made of plate is connected with the truss structure skeleton, the bodyshell weak part is arranged in the framework beam place that constitutes truss structure.
Describedly in the framework beam of truss structure, fill energy-absorbing material.
Described bodyshell weak part is the soldered place that constitutes the plate of bodyshell.
Of the present invention based on bodyshell lightweight solution bodyshell weak part protecting against shock structure, it comprises the bodyshell that is spliced by plate, it also comprises the skeleton that is made of truss structure, bodyshell is connected with skeleton, and the plate splicing of bodyshell is in the framework beam place that constitutes truss structure.
Described plate splicing is welding, and the weld seam of weld is between the two edges of framework beam.
The framework beam of described plate splicing place comprises Liang Yi, is the channel-section rail body between the beam wing, and plate splicing place is positioned at channel-section rail body place.
Fill energy-absorbing material in the described channel-section rail body.
Described bodyshell outer wall is connected with brace panel.
Open spacing connecting bore on the described bodyshell, spacing connecting bore is connected with adapter sleeve, opens connecting bore on the brace panel, and bolt passes connecting bore and is connected with the tapped bore of adapter sleeve.
A kind of new bodyshell weak part method for arranging is proposed in the inventive method, cleverly truss structure is combined with bodyshell, utilize the framework beam of truss structure to be used as the strong form that adds of bodyshell weak part protecting against shock, solve bodyshell weak part protecting against shock problem on the one hand, utilize truss structure to be connected on the other hand with bodyshell, under the precondition that guarantees bus body strength, reduce the use amount of plate material, reduce the weight of bodyshell, for the barycenter that reduces vehicle provides the foundation; Realize the bodyshell lightweight.Truss structure production and processing in the structure of the present invention is convenient, and the plate splicing of bodyshell is in the framework beam place that constitutes truss structure, arranges that enforcement is simple.

The specific embodiment
The inventive method is that the bodyshell that will be pieced together by plate welding and the skeleton of vehicle body truss structure are formed by connecting, and plate is welded the framework beam place that assembly place is arranged on the vehicle body truss structure, and can fill energy-absorbing material in the framework beam at truss structure.
Concrete structure as shown in Figure 1, 2, the bodyshell 300 that plate welding pieces together is connected with the skeleton 400 of vehicle body truss structure.The skeleton 400 of vehicle body truss structure comprises side vertical beam 401, side transverse beam 402, bottom girder 403, bottom cross beam 404, top longeron 405 and head piece 406, the above-mentioned framework beam that is the vehicle body truss structure, how many arranging of above-mentioned beam determines side vertical beam 401 according to the vehicle specific design, side transverse beam 402, bottom girder 403, bottom cross beam 404, the version of top longeron 405 and head piece 406 can be the same or different.
The structure of the soldered impact weakness of the bodyshell that welding pieces together for plate as shown in Figure 3, weldment is connected between bodyshell plate 301 and the bodyshell plate 302, the position of weld seam 303 is over against answering framework beam, be the structure of the bodyshell plate at side vertical beam 401 places shown in the present embodiment figure, promptly the position of weld seam 303 just in time is in side vertical beam 401 places between bodyshell plate 301 and the bodyshell plate 302; The structure of side vertical beam 401 comprises Liang Yi 402, it between the beam wing 402 channel-section rail body 403, two beam wings 402 of both sides are connected with bodyshell plate 302 with bodyshell plate 301 respectively, and weld seam 303 is in channel-section rail body 403 places between bodyshell plate 301 and the bodyshell plate 302; Be provided with in the channel-section rail body 403 and fill energy-absorbing material 500.
Weld seam between the plate of other of formation bodyshell also is in corresponding framework beam place.This not tired one by one stating.
The weld seam between the above-mentioned bodyshell plate and the positional structure of framework beam make and form a closed section between the framework beam of truss structure and the car body shell plate, both guaranteed the structural strength of car body, weakening the position at the commissure protecting against shock again provides the secondary protective capacities.
For the protecting against shock effect of other weak parts of increasing the bodyshell plate, to also have a method be exactly in plate and/or be externally connected with fibre reinforced materials or brace panel.
Present embodiment is an example with the bodyshell plate 405 of side direction as shown in Figure 4, is illustrated: bodyshell plate 405 inwall bonding connection fibre reinforced materials 407; Offer spacing connecting bore 406 on the bodyshell plate 405, spacing connecting bore 406 is connected with adapter sleeve 410; Adapter sleeve 410 is the blind hole covers that offer internal thread hole; Bodyshell plate 405 outer walls are provided with brace panel 408; Open connecting bore 409 on the brace panel 408, bolt 411 passes connecting bore 409 and is connected with the internal thread hole 412 of adapter sleeve 410.
