Along with the development of auto-industry, Federal bumper also moved towards as a kind of important safety device on the road of innovation, occurred plain type bumper/spoiler, hydraulic energy absorption formula bumper/spoiler, bumper/spoiler with various ways such as air cavity type bumper/spoiler and substitute pocket type bumper/spoilers.But plain type bumper/spoiler is simple in structure with it, manufacture and the low advantage of working service cost, remain at present the principal mode of manned vehicle front bumper.And the manned vehicle front bumper of today is except keeping original in automobile self and driver and crew's defencive function, also will pursue harmony and unification, the lightweight of pursuit itself and the defencive function to pedestrian with car body moulding.
Realizing in process of the present utility model, contriver finds that prior art at least exists following problem:
Bumper/spoiler cushion characteristic is bad, and collision shock power can not be absorbed, and automobile can not be effectively protected, and structure is more complicated, and installation and maintenance are inconvenience comparatively.
Summary of the invention
In order to solve the problem of prior art, the utility model embodiment provides a kind of buffer type automobile front bumper.Described technical scheme is as follows:
The utility model embodiment provides a kind of buffer type automobile front bumper, curved plate, oil cylinder, the piston being connected with described oil cylinder that it comprises bumper skin, coordinate with described bumper skin, is assemblied in the bottom girder of described piston and holds riser, is installed on the baffle plate of described piston;
Described buffer type automobile also comprises the first stage clip and the second stage clip that are arranged at described piston with front bumper; Described bumper skin is provided with elastic buffering mechanism.
Particularly, described elastically damping device is set to caoutchouc elasticity shock absorber or synthetic material elastic buffering mechanism, and its inside is solid or hollow.
Particularly, in described bumper skin, be provided with the curved plate that an arcwall face is mated, described curved plate contacts with the piston that several are set up in parallel on the oil cylinder being supported by automotive frame, and on piston, cover has the first stage clip, and the two end supports of curved plate is on the bracing frame that is positioned at shell.
Particularly, described bumper skin is connected with piston, this piston is through bottom girder and force bearing plate, on the piston between bumper/spoiler and bottom girder outside face, the first stage clip is installed, on the piston at bottom girder inside face position, baffle plate is installed, the second stage clip is installed on the piston between baffle plate and force bearing plate, and force bearing plate is fixed on bottom girder by strut.
Preferably, described oil cylinder, described piston all have more than three and three.
The beneficial effect that the technical scheme that the utility model embodiment provides is brought is:
By be arranged at piston stage clip, be arranged at the elastic buffering mechanism of bumper skin; realize bumper/spoiler secondary buffer; collision shock power is absorbed preferably; thereby automobile is effectively protected; the utlity model has simple in structure; installation and maintenance are convenient, and the advantages such as low cost are applicable to various automobiles and install.
Brief description of the drawings
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the buffer type automobile front bumper arrangement schematic diagram that the utility model embodiment provides.
Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, the utility model embodiment is described in further detail.
The utility model embodiment provides a kind of buffer type automobile front bumper, referring to Fig. 1, described buffer type automobile comprises bumper skin 1, the curved plate 2, oil cylinder 3, the piston 4 being connected with oil cylinder 3, the first stage clip 5 that is arranged at piston 4 and the second stage clip 9 that coordinate, is equipped with the bottom girder 6 of piston 4 and holds riser 7, be installed on the baffle plate 8 of piston 4 with bumper skin 1 with front bumper.
Bumper skin 1 end face is provided with elastic buffering mechanism 11; Elastic buffering mechanism 11 use high-tension rubber or high-tension synthetic material are made, and its inside is solid or hollow.
In bumper skin 1, be provided with the curved plate 2 that an arcwall face is mated, curved plate 2 contacts with the piston 4 that several are set up in parallel on the oil cylinder 3 being supported by automotive frame, on piston 4, cover has the first stage clip 5, and the two end supports of curved plate 2 is on the bracing frame 12 that is positioned at shell 1.
Bumper skin 1 is connected with piston 4, this piston 4 is through bottom girder 6, force bearing plate 7, on the piston 4 between bumper/spoiler 1 and bottom girder 6 outside faces, the first stage clip 5 is installed, on the piston 4 at bottom girder 6 inside face positions, baffle plate 8 is installed, the second stage clip 9 is installed on the piston 4 between baffle plate 8 and force bearing plate 7, force bearing plate 7 is fixed on bottom girder 6 by strut 71, in the time that automobile bumps, stressed first stage clip 5 that makes of bumper skin 1 is first compressed, realize first order buffering, piston 4 moves backward, baffle plate 7 is moved thereupon backward, compress the second stage clip 9, realize second stage buffering, collision shock power absorbs through secondary buffer, can reduce to greatest extent injury, obtain actv. protection, the utility model adopts three pistons, the headstock and the tailstock that are suitable for light car are installed, can suitably select the quantity of piston according to different automobile types.
