Specific embodiment
Below against attached drawing, by the description of the embodiment, making to a specific embodiment of the invention further details of
Explanation.
Energy-absorbing efp of the present invention, as shown in Figure 1, including that the pedal tread 1, pedal arm 2 and pedal being connected connect
Support 3 is connect, pedal mounting surface 4 and body platform installation connect, which is made of composite glass fiber material, pedal arm 2
It is equipped with the energy-absorbing region of fracture that the power that is hit can be broken.It is broken herein by positive stress, alleviates cushion effect, driven with protecting
The safety of the right leg of member.Material of the PP+GF30 or higher containing glass, the plasticity of this material may be selected in the own material of gas pedal
Intensity is essentially identical with steel, it is ensured that the intensity of gas pedal.
In the present invention, as shown in Fig. 2, the energy-absorbing region of fracture includes the fracture induction slot 6 being located on 2 side wall of pedal arm.It is disconnected
Induction slot 6 is split to be located on 2 side wall of pedal arm, for the semi-circular recesses that are recessed inwardly along its thickness direction, and be broken induction slot 6 by
2 upper end of pedal arm extends downwardly.The effect of fracture induction slot 6 is the structural strength reduced herein, and when receiving impact force, throttle is stepped on
Thus place starts to be broken plate.
In the present invention, to guarantee the structural strength of gas pedal during normal driving, it is preferred that controlled fracturing blasting induces slot 6
Semi-cylindrical canyon radius, fracture induction slot 6 place 2 wall thickness minimum of pedal arm at be 1.3mm to 2.0mm.
As shown in Figure 2, the triangular groove 7 for being located at fracture induction 6 lower section hollow out of slot is additionally provided on pedal arm 2.Triangular groove 7
Upper apex angle connects with fracture induction 6 lower end of slot, and bottom edge is fracture belt 8, is equipped with close to bottom edge medium position along 1 thickness side of pedal arm
To the breaking groove 9 of extension, the 9 position regional fracture of breaking groove along fracture belt 8 is driven with induction.Fracture position is by pedal sheet
The triangular groove 7 on body, which is laid out, to be determined, hollow layout is the intensity to weaken the region of fracture, while triangular layout also functions to
Guarantee the effect of structural strength in 2 normal driving process of pedal arm.
In the present invention, it is preferred that breaking groove 9 is semi-circular recesses, and minimum wall thickness (MINI W.) is 1.3mm to 2.0mm at fracture belt 8,
To guarantee the structural strength of gas pedal during normal driving.
The setting of the gas pedal by inductive cleavage handle so that it is hit the masterpiece used time in fracture belt 8 close
It is broken at middle part breaking groove 9, to obtain optimal fracture energy absorption effect, to avoid on top of the triangular groove 7 far from pedal tread one end
Forced breakage at angle can be equipped with guiding circular hole 10 here, will disperse concentrated force herein, play certain fracture guiding and make
With.
In the present invention, it is preferred that for the structural strength for enhancing entire gas pedal, guarantee that the intensity of normal driving process is wanted
It asks, is equipped with several reinforcing ribs 11 close to the side of pedal mounting surface on pedal arm 2.
Vehicle is in impact test, it is desirable that chief aviation pilot's right crus of diaphragm is placed in gas pedal, so as to come when investigating collision pairs
The injury values of the right leg of driver, to evaluate overall collision result.The impact force formed in collision passes through right leg front
It is first transmitted at fracture induction slot 6 to the power of gas pedal, fracture variation occurs after stress, power passes down at fracture belt 8
Occur to be broken and fall off, as shown in Figure 3.During gas pedal forced breakage, to alleviate the stress value of leg, preferably
Protect the injury of the right leg of driver.
Forced breakage value because being related to fracture induction slot 6 and fracture belt 8 requires, need to be to throttle for region of fracture intensity
Pedal makes a strength test, the fracture position and force value of confirmation fracture belt 8 and fracture induction slot 6, and confirmation normal use feelings
There is a phenomenon where be broken under condition；By the position to fracture induction slot 6, the parameters such as position size of groove depth and triangular groove
Control adjust to obtain the balance of intensity in breaking strength and normally travel.For vehicle performance, need to drive in collision
The injury of the right leg of member carries out 3D data vehicle CAE verifying analysis and real vehicle collision test verifying, to carry out confirmation driver's leg
Whether the injury in portion meets complete automobile collision performance to the technical requirements of human body.
Energy-absorbing efp of the present invention, the lightweight weight of gas pedal, structure sets denaturation and is promoted, with traditional function
Can be identical unchanged, and reduce the purchase cost of components.Weight saving has local material reducing, effectively using injection molding
The weight for reducing electronic throttle assembly, certain contribution is provided for vehicle lightweight；Cost reduces, opposing metallic part cost
It reduces；Structure sets denaturation and is promoted, and effectively, easily can be designed change by changing injection mold, have total member more
The high platform property continued to use；When vehicle collides, it is broken by frontal impact power, cuts off the conduction of power, driving can be effectively protected
The injury of the right leg of member.
The present invention is exemplarily described above in conjunction with attached drawing, but the present invention is not limited to aforesaid way, only
The improvement for the various unsubstantialities to be carried out using the inventive concept and technical scheme of the present invention directly applies to other occasions
, it falls within the scope of protection of the present invention.
