Description

Long-stroke electric pedal and vehicle Technical Field

[0001] The utility model relates to the field of automobiles, in particular to a long-stroke electric pedal and a vehicle. Background Art

[0002] In some SUV and MPV models, since their chassis are higher than that of cars, it is not convenient for drivers and passengers to get on and off the vehicle. Therefore, these models are generally equipped with pedals to assist drivers and passengers in getting on and off the vehicle, and the pedals are generally divided into fixed pedals and electric pedals. The fixed pedals are fixedly installed on the vehicle body, and the electric pedals drive the pedal body through an electric drive structure, so that the pedal body can move relative to the vehicle body; however, in order to obtain a longer Y-axis stroke, the existing electric pedals are designed to have a longer swing arm, which accordingly increases the Z-axis stroke of the electric pedal, making the electric pedal occupy a larger space in the Z-axis direction when in the retracted state and the extended state, and the electric pedal with this structure requires a larger swing angle to achieve a long Y-axis stroke, and is prone to scratching against ground obstacles during driving and causing damage; therefore, there is an urgent need for a long-stroke electric pedal and vehicle to solve the above problems.

[0027] 1 to 4 , a long-stroke electric pedal includes a pedal body 10 , a first mounting base 20 , a second mounting base 30 , a driving device 40 , and two transmission assemblies 50 ;

[0028] The first mounting base 20 is connected to one end of the pedal body 10 through a set of transmission components 50;

[0029] The second mounting base 30 is connected to the other end of the pedal body 10 through another set of transmission components 50;

[0030] The driving device 40 is connected to the transmission assembly 50 to drive the pedal body 10 to extend or retract through the transmission assembly 50;

[0031] The transmission assembly 50 includes a first swing arm 51 and a second swing arm 52, one end of the first swing arm 51 and one end of the second swing arm 52 are hinged to the first mounting seat 20 or the second mounting seat 30, and the other end of the first swing arm 51 and the other end of the second swing arm 52 are hinged to one end or the other end of the pedal body 10, and the angle α between the center line A1 of the first swing arm 51 and the center line A2 of the second swing arm 52 when the pedal body 10 is in the retracted state is an acute angle, and the intersection of the center line A1 of the first swing arm 51 and the center line A2 of the second swing arm 52 when the pedal body 10 is in the retracted state is located above the connection point B between the drive device 40 and the transmission assembly 50.

[0032] In the present invention, the first mounting seat 20 and the second mounting seat 30 are mounted on the chassis of the vehicle body, and the driving device 40 is electrically connected to the driving computer. When the driving device 40 receives the control command sent by the driving computer, it will drive one end of the second swing arm 52 to rotate through its output shaft, so that the first swing arm 51 and the second swing arm 52 swing, and then drive the pedal body 10 to extend outward, that is, to change from the state of Figure 3 to the state of Figure 4; it should be noted that there are two groups of transmission components 50, the first group is connected between the first mounting seat 20 and one end of the pedal body 10, and the second group is connected between the second mounting seat 30 and the other end of the pedal body 10. All parameters in the present invention are based on the same group of transmission components 50. Referring to Figure 3, in the first group of transmission components 50, one end of the first swing arm 51 is hinged to the second mounting seat 30, and the other end of the first swing arm 51 is hinged to the pedal body 10, one end of the second swing arm 52 is hinged to the second mounting seat 30, the other end of the second swing arm 52 is hinged to the other end of the pedal body 10, and the angle α between the center line A1 of the first swing arm 51 and the center line A2 of the second swing arm 52 when the pedal body 10 is in the retracted state is an acute angle, and the intersection of the center line A1 of the first swing arm 51 and the center line A2 of the second swing arm 52 when the pedal body 10 is in the retracted state is located above the connection point B between the drive device 40 and the transmission assembly 50, which can enable the first swing arm 51 and the second swing arm 52 to achieve a larger Y-axis stroke with a smaller swing angle when swinging; the advantage of the utility model is that: through the above structure, a larger Y-axis stroke can be achieved with a smaller swing angle, which not only reduces the volume of the electric pedal, but also increases the extended length of the pedal body, which is more convenient for passengers to get on and off the vehicle.

[0033] When the pedal body 10 is in the retracted state, an included angle α between a center line A1 of the first swing arm 51 and a center line A2 of the second swing arm 52 is greater than 5° and less than 90°.

[0034] The angle β between the upper end surface of the pedal body 10 and the horizontal plane when the pedal body 10 is in the retracted state is ≤15°, and the angle γ between the upper end surface of the pedal body 10 and the horizontal plane when the pedal body 10 is in the extended state is ≤5°; in summary, this setting, a smaller angle difference can reduce the movement of the pedal body 10 in the Z-axis direction during the extension process, thereby obtaining more movement in the Y-axis direction, and further achieving an increase in the Y-axis direction stroke.

[0035] As a preferred embodiment of the driving device 40, the driving device 40 is configured as a motor, the output shaft of the motor is connected to one end of the first swing arm 51 or one end of the second swing arm 52, and the rotation angle δ of the output shaft of the motor is ≤130°; this setting enables the output shaft of the motor to achieve an extension distance of the pedal body 10 in the Y-axis direction of ≥100 mm at a smaller rotation angle (the first swing arm 51 and the second swing arm 52 at a smaller swing angle).

[0036] There is a first hinge point C1 between the first swing arm 51 and the first mounting seat 20 or the second mounting seat 30, a second hinge point C2 between the second swing arm 52 and the first mounting seat 20 or the second mounting seat 30, a third hinge point C3 between the first swing arm 51 and one end of the pedal body 10 or the other end of the pedal body 10, and a fourth hinge point C4 between the second swing arm 52 and one end of the pedal body 10 or the other end of the pedal body 10. When the pedal body 10 is in a retracted state, the distance in the Y-axis direction between the two hinge points farthest apart from each other among the first hinge point C1, the second hinge point C2, the third hinge point C3 and the fourth hinge point C4 is ≤98mm; this setting can control the overall width of the pedal body 10 in the Y-axis direction within 98mm when it is in a retracted state, thereby reducing the space in the Y-axis direction of the vehicle body occupied by the electric pedal.

[0037] There is a first hinge point C1 between the first swing arm 51 and the first mounting seat 20 or the second mounting seat 30, a second hinge point C2 between the second swing arm 52 and the first mounting seat 20 or the second mounting seat 30, a third hinge point C3 between the first swing arm 51 and one end of the pedal body 10 or the other end of the pedal body 10, and a fourth hinge point C4 between the second swing arm 52 and one end of the pedal body 10 or the other end of the pedal body 10. When the pedal body 10 is in a retracted state, the distance between the two hinge points farthest apart in the Z-axis direction among the first hinge point C1, the second hinge point C2, the third hinge point C3 and the fourth hinge point C4 is ≤50 mm in the Z-axis direction; this setting can control the overall height of the pedal body 10 in the Z-axis direction within 50 mm when it is in a retracted state, minimize the space occupied by the electric pedal in the Z-axis direction of the vehicle body, maximize the distance between the electric pedal and the ground, and avoid the electric pedal from scraping the ground when the vehicle is driving.

[0038] A vehicle comprises the electric pedal.

Those skilled in the art may make equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications and substitutions are all included in the scope defined by the claims of this application.
