Abstract
The utility model provides a variable pedal ratio braking pedal structure of an electro-mobile, and belongs to the technical field of the electro-mobile. The variable pedal ratio braking pedal structure comprises a pedal and a braking connecting rod, wherein a pedal shaft is arranged on the pedal; a rotating shaft of the connecting rod is arranged at one end of the braking connecting rod; a fixed braking pushing rod hole is formed in the other end of the braking connecting rod; a pedal head is arranged on the pedal; an arc contacting position is arranged on the braking connecting rod; the pedal head is propped against the arc contacting position. The variable pedal ratio braking pedal structure has the advantage that the braking connecting rod is additionally arranged on the conventional base, so that the braking connecting rod can drive a braking master cylinder to work, and the variable pedal ratio braking pedal structure of which the braking force is enhanced, can be realized without the help of other power sources. Therefore, an ideal braking effect can be achieved under the condition that the electro-mobile does not consume electrical energy and driving staff does not consume too much physical strength.
Description
Technical field
The utility model belongs to automobile brake accessory technical field, relates to a kind of electronlmobil and becomes pedal ratio brake pedal structure.
Background technology
Along with the consumption day by day of oil and the rise of price, the energy source of adding electronlmobil is general, can obtain from a lot of approach, so the universal of electronlmobil will be trend of the times, it is perfect that but the closed-center system of electronlmobil does not also develop, plumbic acid, lithium electricity waits the capacitance of storage of storage battery limited, if the brake system of electronlmobil also adopts force aid system for braking, on electronlmobil, limited electric energy will be braked force aid system and consume a part so, weaken the course continuation mileage of electronlmobil, so adopting the brake system of non-power-assisted is a kind of means that electronlmobil increases course continuation mileage indirectly.But when having saved the energy, braking effect can not weaken, and laborsaving, becoming pedal ratio brake pedal can address this is that.
Summary of the invention
Technical problem to be solved in the utility model is the present situation for prior art, and provides a kind of simple in structure, and braking labour-saving electronlmobil becomes pedal ratio brake pedal structure.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of electronlmobil becomes pedal ratio brake pedal structure, it is characterized in that, comprise pedal and brake connecting rod, on pedal, be provided with pedal shaft, on one end of described brake connecting rod, be provided with connecting rod rotating shaft, on the other end, offer fixing brake push rod hole, on described pedal, be provided with pedal head, on brake connecting rod, be provided with camber line contact position, described pedal head is resisted against on camber line contact position.
The improvement of the utility model maximum is to have increased brake connecting rod, drag master cylinder push rod is to be directly connected with fixing brake push rod hole, existing standard machinery brake pedal is certainty ratio, namely drag master cylinder push rod and pedal are directly connected through the hinge, because each interface point is fixed, thus at push down on the pedal to having braked, the size of its braking force is along with the ratio that is varied to of pedal force changes, in whole process, people does not have laborsaving.The utility model is along with the carrying out of braking, connection location between pedal and brake connecting rod changes, also move to the S. A. direction of stretcher the fixed position that is just equal to drag master cylinder push rod, namely increases pedal ratio, thereby reach labour-saving object.
The measure of taking for optimization such scheme specifically comprises:
Become in pedal ratio brake pedal structure at above-mentioned a kind of electronlmobil, described pedal head and camber line contact between position and are also provided with pulley.Ensure like this this reliability of structure, stretcher is made into friction of rolling with contacting of brake connecting rod, allow cliding friction become friction of rolling.
Compared with prior art, the utility model has the advantage of on original basis and increase brake connecting rod, drive the work of drag master cylinder by brake connecting rod like this, not by other propulsions source in the situation that, can realize the change pedal ratio brake pedal structure that braking force increases, can allow electronlmobil in the situation that not consuming electric energy, reach desirable braking effect, and allow navigating mate not consume too large muscle power.
Brief description of the drawings
Fig. 1 is that this electronlmobil becomes the constitution diagram before the braking of pedal ratio brake pedal structure;
Fig. 2 is that this electronlmobil becomes the constitution diagram after the braking of pedal ratio brake pedal structure;
Fig. 3 is the structural representation with pulley in Fig. 2.
Detailed description of the invention
Be below specific embodiment of the utility model by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.
In figure, pedal 1; Brake connecting rod 2; Pedal shaft 3; Connecting rod rotating shaft 4; Fixing brake push rod hole 5; Pedal head 6; Camber line contact position 7; Pulley 8.
As shown in Figure 1, this electronlmobil becomes pedal ratio brake pedal structure, comprise pedal 1 and brake connecting rod 2, on pedal 1, be provided with pedal shaft 3, here the fixing back step 1 of pedal shaft 3 just can rotate around pedal shaft 3, on one end of brake connecting rod 2, be provided with connecting rod rotating shaft 4, on the other end, offer fixing brake push rod hole 5, fixing brake push rod hole 5 is connected with outside drag master cylinder push rod, on pedal 1, be provided with pedal head 6, on brake connecting rod 2, be provided with camber line contact position 7, pedal head 6 is resisted against on camber line contact position 7.Here key point is, the relative position of pedal shaft 3 and connecting rod rotating shaft 4, and the relative position of pedal 1 and brake connecting rod 2, the setting of the local camber line contacting with pedal 1 on brake connecting rod 2, this camber line arranges and will have influence on the kinematic velocity of drag master cylinder push rod.
As shown in Figure 3, as another kind of mode, pedal head 6 and camber line contact between position 7 and are also provided with pulley 8, ensure like this this reliability of structure, and pedal 1 is made into friction of rolling with contacting of brake connecting rod 2, allow cliding friction become friction of rolling.
In the time of braking, brake connecting rod 2 moves around connecting rod rotating shaft 4, because other end is connected with drag master cylinder push rod, brake connecting rod 2 is pushed as shown in Figure 2, the transmittance process of whole braking force is as follows: pedal 1 passes to brake connecting rod 2 power, brake connecting rod 2 can rotate around connecting rod rotating shaft 4, and the fixing brake push rod hole 5 of other one end of brake connecting rod 2 is connected with drag master cylinder push rod, thereby promote the work of drag master cylinder, at pedal 1 Input Forces constant in the situation that, brake efficiency be common 2.15 times, also explanation will obtain same brake efficiency, this kind of new structure is more laborsaving.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various amendments or supplements or adopt similar mode to substitute described specific embodiment, but can't depart from the defined scope of spirit of the present utility model.
