Detailed Description
The following describes embodiments of the present invention with reference to the drawings.
As shown in fig. 1-4, the downshift structure of a vehicle pedal of the present embodiment includes a pedal base 1, a pedal arm 2 is hinged on the pedal base 1, a wedge-shaped groove 201 is provided on a side of the pedal arm 2 facing the pedal base 1, and a downshift housing 301 is movably connected in the wedge-shaped groove 201; an elastic component 3 is connected between the downshift housing 301 and the pedal arm 2, and the elastic component 3 deforms and contracts towards the interior of the wedge-shaped groove 201 when the downshift housing 301 is pressed by an external force.
The elastic assembly 3 comprises a downshift spring 302, and the downshift spring 302 is perpendicular to the groove depth of the wedge-shaped groove 201; the downshift rollers 303 are provided at both ends of the downshift spring 302.
The downshift roller 303 is movably connected to an end of the downshift spring 302.
The amount of displacement of the two downshift rollers 303 in the wedge-shaped groove 201 in the axial direction of the downshift spring 302 is greater than or equal to the amount of deformation of the downshift spring 302.
The kick-down spring 302 is embedded in the kick-down case 301.
The size of the downshift housing 301 matches the size of the mouth of the wedge-shaped groove 201, and the downshift rollers 303 and the downshift springs 302 are retained in the wedge-shaped groove 201 by the downshift housing 301. A gap h shown in fig. 4 is reserved between the initial state of the downshift housing 301 and the bottom of the wedge groove, and h in this embodiment is set to a distance of 20-25mm, and the end point values may be 20mm and 25mm, or the middle value may be 23mm or 24mm.
The end of the kickdown housing 301 that falls into the wedge slot 201 is shaped to fit the bottom of the wedge slot 201.
Both ends of the kickdown case 301 in the axial direction of the kickdown spring 302 are respectively provided in a convex manner, and the kickdown rollers 303 are dropped on the convex positions.
The pedal base 1 is provided with a limiting surface corresponding to a position where the kickdown housing 301 falls on the pedal base 1 when the pedal arm 2 is depressed.
The specific structure and working process of the embodiment are as follows:
as shown in fig. 1 and 2, the kickdown structure includes a pedal base 1 and a pedal arm 2, and a side of the pedal arm 2 facing the pedal base 1 is recessed to form a wedge-shaped groove 201, and a kickdown case 301 is embedded.
Referring to fig. 3 and 4, the bottom of the kickdown housing 301 is square and fits the shape of the mouth of the wedge groove 201. The end of the down shift housing 301 which falls in the wedge groove 201 is embedded with a down shift spring 302, and both ends of the down shift spring 302 are located at the open position of both ends of the down shift housing 301, which position corresponds to the position of the down shift roller 303. The downshift housing 301 is restricted by a snap structure provided on the pedal base 1, and does not fall out of a wedge-shaped groove of the downshift housing 1 on the premise of not being affected by external force. As shown in fig. 5, a catch extends from the downshift housing 301, and the catch catches the pedal arm 2, so that the downshift housing 301 is connected to the pedal arm 2.
The kickdown case 301, the kickdown spring 302 end face of the initial state form a right angle space for accommodating the kickdown roller 303. When the pedal arm 2 is stepped down, the downshift housing 301 contacts with the limiting surface of the pedal base 1 below, then the driver continues to apply force to step down deeply, at this time, the downshift housing 301 retracts into the wedge-shaped groove 201, the two downshift rollers 303 are pushed to move oppositely along the inclined surface of the wedge-shaped groove 201, and the downshift spring 302 is squeezed, so that the force which the driver needs to overcome actually comprises the force of spring compression, and is different from the previous stepping force, and the driver feels the driving experience of violent stepping down and accelerating.
The above description is for the purpose of explanation and not limitation of the invention, which is defined in the claims, and any modifications may be made within the scope of the invention.
