Description
Technical field
The present invention relates to automobile technical field, refer to a kind of crushing type pedal crumple mechanism especially and there is the automobile of this mechanism.
Background technology
At vehicle generation severe crash, when there is larger displacement to driving compartment direction in fireproof brickwork, be fixed on vacuum booster on fireproof brickwork and brake pump assembly, pedal support etc. can together move afterwards, servo-unit push rod moves after driving pedal arm, is very easy to the grievous injury causing chaufeur shank.
In " C-NCAP rule (version in 2012) ", front 40% overlapping deformable obstacle Collision test speed brings up to 64km/h by 56km/h, vehicle deformation can be more serious, and after pedal, the amount of moving also can be larger, and this certainly will cause even more serious injury to chaufeur.When customer is more and more higher to vehicle collision safety requirements, strengthening the protection of chaufeur is the important topic of not allowing to avoid.2.1.1.1.5 shank position scoring in, to chaufeur shank injury judgment criteria made clear and definite regulation:
This position top score is 2 points, so minimum that to be divided into 0 point.
Shank position score produces by measuring dummy's index of correlation, and its critical for the evaluation has: the tibia index (TI) and shank compressive force, and the corresponding best result of each index is 2 points.
High Performance limit value: the tibia index (TI) 0.4 shank compressive force 2kN
Low performance limit value: the tibia index (TI) 1.3 shank compressive force 8kN
Therefore, need a kind of safe class high, can collision free time pedal arm after the automobile that moves, to protect the safety of chaufeur.

Detailed description of the invention
For embodiments of the invention will be solved technical matters, technical scheme and advantage clearly, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
Embodiments of the invention move after pedal arm during vehicle collision in prior art, the problem easily causing chaufeur shank to injure, provide a kind of safe class high, can collision free time pedal arm after the crushing type pedal crumple mechanism that moves and the automobile with this mechanism.
First it should be noted that, owing to the present invention relates to automobile and being arranged in the crushing type pedal crumple mechanism of automobile, therefore, the directions such as the "front", "rear" mentioned in 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 crushing type pedal crumple mechanism, as shown in Figure 1 to Figure 3, comprise pedal support 1 and be arranged on the pedal arm 3 on pedal support 1 by S. A. 2, the two ends of S. A. 2 are fixed on pedal support 1, pedal arm 3 is connected to the middle part of S. A. 2, can break the Impactor 4 of S. A. 2 when this crushing type pedal crumple mechanism is also included in collision.In figure 3,7 is pedal.
When colliding, the Impactor 4 in the present invention can break S. A. 2, and pedal arm 3 is come off, thus moves the injury to chaufeur shank after can effectively avoiding pedal arm, improves vehicle collision score, meets the safe class of complete automobile collision.
For making S. A. 2 more easily be pressed down when meeting normal operating needs, S. A. 2 is preferably hollow rotary shaft.Certainly, S. A. can also adopt other modes to be more easily pressed down, such as, select the suitable material of intensity, design structure of being easily pressed down etc. on the rotary shaft.
For breaking S. A. 2, Impactor 4 can adopt and directly to break or oblique compression such as to break at the mode, in the present invention, the mode that preferred employing oblique compression breaks, particularly: the front end of pedal support 1 is fixed on vehicle body together with Impactor 4, the rear end of Impactor 4 is between the upper surface of pedal support 1 and S. A. 2, and the thickness of Impactor 4 increases progressively from rear end to middle part (Fig. 1 shown in label 5).
Like this, because the distance between the upper surface of pedal support 1 and S. A. 2 is certain, when colliding, move along with after Impactor 4, and because the thickness of Impactor 4 increases progressively from rear end to middle part, the rear end of Impactor 4 will extrude gradually and break S. A. 2, pedal arm 3 is come off, thus moves the injury to chaufeur shank after avoiding pedal arm.
And, under above-mentioned oblique compression breaks mode, be the normal work making Impactor 4 not disturb S. A. 2, the rear end of Impactor 4 does not preferably contact S. A. 2 in normal state, keeps certain distance, and chaufeur is by pushes pedals arm 3, pedal arm 3 normally rotates, and promotes other structures.
In addition, because the front end of pedal support 1 is fixed on vehicle body together with Impactor 4, break the opportunity of S. A. 2 for controlling Impactor 4, the front end of pedal support 1 can be designed with distortion fault structure (fracture port 6 shown in Fig. 2) when colliding.The initial stage is moved during collision, the front-end and back-end being fixed on the pedal support 1 on vehicle body are moved simultaneously, but because plastic deformation occurs in the front end of pedal support 1, the rear end amount of movement of pedal support 1 is made to be greater than front end, when after move residual quantity arrive certain numerical value time, there is failure type fracture in fracture port 6 place of pedal support 1, now the front-end and back-end of pedal support 1 depart from completely, and relative motion occurs at this moment.Because the front end of Impactor 4 with pedal support 1 is fixed together, therefore the rear end of pedal support 1 is same with Impactor 4 also there is relative motion, and then makes Impactor 4 break S. A. 2.
On the other hand, the present invention also provides a kind of automobile, there is crushing type pedal crumple mechanism, as shown in Figure 1 to Figure 3, this crushing type pedal crumple mechanism is comprised pedal support 1 and is arranged on the pedal arm 3 on pedal support 1 by S. A. 2, the two ends of S. A. 2 are fixed on pedal support 1, and pedal arm 3 is connected to the middle part of S. A. 2, can break the Impactor 4 of S. A. 2 when crushing type pedal crumple mechanism is also included in collision.
In the present invention, when colliding, Impactor 4 can break S. A. 2, and pedal arm 3 is come off, thus moves the injury to chaufeur shank after can effectively avoiding pedal arm, improves vehicle collision score, meets the safe class of complete automobile collision.
For making S. A. 2 more easily be pressed down when meeting normal operating needs, S. A. 2 is preferably hollow rotary shaft.
Break S. A. 2 for convenience, the mode that Impactor 4 preferably adopts oblique compression to break, particularly: the front end of pedal support 1 is fixed on vehicle body together with Impactor 4, the rear end of Impactor 4 is between the upper surface of pedal support 1 and S. A. 2, and the thickness of Impactor 4 increases progressively from rear end to middle part (Fig. 1 shown in label 5).For the normal work making Impactor 4 not disturb S. A. 2, the rear end of Impactor 4 does not preferably contact S. A. 2 in normal state.Preferably, the front end of pedal support 1 can also be designed with distortion fault structure (fracture port 6 shown in Fig. 2) when colliding.
The above is the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing 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.
