The specific embodiment
For technical matters, technical scheme and advantage that embodiments of the invention will be solved is clearer, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
Embodiments of the invention are for moving behind the pedal arm during vehicle collision in the prior art, easily cause the problem of chaufeur shank injury, a kind of safe class folding wall type high, that move behind the pedal arm in the time of can avoiding colliding pedal crumple mechanism is provided and has the automobile of this mechanism.
At first need to prove, owing to the present invention relates to automobile and being arranged in the folding wall type pedal crumple mechanism of automobile, therefore, the directions such as the 'fornt', 'back' of mentioning among the present invention are all consistent with the direction such as forward and backward of automobile.
On the one hand, the invention provides a kind of folding wall type pedal crumple mechanism, as shown in Figure 1 to Figure 3, comprise pedal support 11,31 and be installed in pedal arm 33 on the pedal support 11,31 by S. A. 12,32, S. A. 12,32 two ends are fixed on pedal support 11,31 the two side, pedal arm 33 is connected to S. A. 12,32 middle part, and this folding wall type pedal crumple mechanism can break the Impactor 14,34 of pedal support 11, at least one sidewall of 31 when also being included in collision.
When bumping, Impactor 14 among the present invention, 34 can break pedal support 11, at least one sidewall of 31, S. A. 12,32 is come off, and then pedal arm 33 is also come off, thereby can effectively avoid moving behind the pedal arm injury to the chaufeur shank, improve the vehicle collision score, satisfied the safe class of car load collision.
For conveniently breaking the sidewall of pedal support, preferably adopt the Impactor of wedge shape to push, specifically can adopt following two kinds of frame modes:
(1) front end of pedal support and Impactor are fixed on the vehicle body together, the rear end of Impactor is between the two side of pedal support, rear end one side of Impactor is wedge shape, the shape of the shape of the sidewall of pedal support and the rear end of Impactor adapt (also for wedge shape).This structural principle as shown in Figure 4, wherein, 44 is Impactor, 41 is pedal support, in when collision, Impactor 44 can break a sidewall of pedal support 41.Folding wall type pedal crumple mechanism shown in Fig. 1 and Fig. 2 namely is to adopt this structure.
(2) front end of pedal support and Impactor are fixed on the vehicle body together, and the rear end of Impactor is between the two side of pedal support, and the both sides, rear end of Impactor all are wedge shape, and the shape of the shape of the sidewall of pedal support and the rear end of Impactor adapts.This structural principle as shown in Figure 5, wherein, 54 is Impactor, 51 is pedal support, in when collision, Impactor 54 can break two sidewalls of pedal support 51 simultaneously.Folding wall type pedal crumple mechanism shown in Fig. 3 namely is to adopt this structure.
Like this, because the distance between the pedal support two side is certain, and Impactor is wedge shape, when collision, along with moving behind the Impactor, Impactor pushes and breaks the sidewall (one or both sides) of pedal support gradually, and S. A. is come off, and then pedal arm is also come off, thereby can effectively avoid moving behind the pedal arm injury to the chaufeur shank.
For avoiding that the normal operation of pedal support is caused interference, as shown in Figure 3, the rear end of Impactor 34 does not preferably contact the sidewall of pedal support 31 under normal condition, keep certain distance.In Fig. 3,37 is pedal.
In addition, because front end and the Impactor of pedal support are fixed on the vehicle body together, break the opportunity of the sidewall of pedal support for the control Impactor, the front end of pedal support can be designed with distortion fault structure (fracture port 16 shown in Fig. 1 and Fig. 2) when collision.Move the initial stage during collision, the front-end and back-end of being fixed in the pedal support on the vehicle body are mobile simultaneously, but because the front end generation plastic deformation of pedal support, so that the rear end amount of movement of pedal support is greater than front end, when after move residual quantity when arriving certain numerical value, the failure type fracture occurs in fracture port 16 places of pedal support, and this moment, the front-end and back-end of pedal support broke away from fully, and relative motion occurs at this moment.Because the front end of Impactor and pedal support is fixed together, so relative motion equally also occurs in the rear end of pedal support and Impactor, and then so that Impactor breaks the sidewall of pedal support.
On the other hand, the present invention also provides a kind of automobile, has above-mentioned folding wall type pedal crumple mechanism, as shown in Figure 1 to Figure 3, this folding wall type pedal crumple mechanism comprises pedal support 11,31 and be installed in pedal arm 33 on the pedal support 11,31 by S. A. 12,32, S. A. 12,32 two ends are fixed on pedal support 11,31 the two side, pedal arm 33 is connected to S. A. 12,32 middle part, and folding wall type pedal crumple mechanism can break the Impactor 14,34 of pedal support 11, at least one sidewall of 31 when also being included in collision.
When bumping, Impactor 14 among the present invention, 34 can break pedal support 11, at least one sidewall of 31, S. A. 12,32 is come off, and then pedal arm 33 is also come off, thereby can effectively avoid moving behind the pedal arm injury to the chaufeur shank, improve the vehicle collision score, satisfied the safe class of car load collision.
Similarly, for conveniently breaking the sidewall of pedal support, preferably adopt the Impactor of wedge shape to push, specifically can adopt following two kinds of frame modes:
(1) front end of pedal support and Impactor are fixed on the vehicle body together, and the rear end of Impactor is between the two side of pedal support, and rear end one side of Impactor is wedge shape, and the shape of the shape of the sidewall of pedal support and the rear end of Impactor adapts.
(2) front end of pedal support and Impactor are fixed on the vehicle body together, and the rear end of Impactor is between the two side of pedal support, and the both sides, rear end of Impactor all are wedge shape, and the shape of the shape of the sidewall of pedal support and the rear end of Impactor adapts.
For avoiding that the normal operation of pedal support is caused interference, the rear end of Impactor does not preferably contact the sidewall of pedal support under normal condition, keep certain distance.Preferably, the front end of pedal support can also be designed with distortion fault structure when collision.
The above is preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from principle of the present invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
