The lock fork 4 is fixed on the frame 1, the front end of the lock fork 4 is provided with a clamping groove, one end of the lock fork, which is back to the pedal 2, is taken as the front end, the clamping groove is in an obtuse V shape, and the opening of the clamping groove is slightly deviated downwards towards the right front or the front; the lock pin 31 is fixed on the locking link 3, the lock pin 31 is arranged on the side of the locking link 3 in a protruding mode, and the lock pin 31 can move along the upper edge of the lock fork 4 and can be clamped into the clamping groove. The locking fork 4 is a plate-like structure, the edge of which can contact the locking pin 31 to provide guidance.
Referring to fig. 3, a schematic diagram of the movement path of the pedal parking brake device of the present invention is shown; in the figure, an arrow denoted by a reference numeral (r) indicates a path of the lock pin 31 during the parking brake process, and an arrow denoted by a reference numeral (c) indicates a path of the lock pin 31 during the release of the parking brake process. During parking braking, the pedal 2 is stepped on, the lock pin 31 moves forwards along the lock fork 4, the locking connecting rod 3 rotates correspondingly, when the lock pin 31 reaches the foremost end of the upper edge, the lock pin moves downwards under the action of the elastic force of the second elastic reset piece 32 and is clamped into a clamping groove arranged at the front end of the lock fork 4, the inhaul cable mechanism 22 is tensioned to realize the parking braking function, and the pedal 2 is pulled by the locking connecting rod 3 to keep a stepping state.
When the brake is released, the pedal 2 is repeatedly stepped downwards, the pedal 2 pushes the locking connecting rod 3, so that the lock pin 31 moves downwards under the action of the elastic force of the second elastic resetting piece 32, when the pedal moves to the lowest edge of the clamping groove, the pedal moves out of the clamping groove, the lock pin 31 crosses the lock fork 4 and returns to the original state without being stepped, and the pedal 2 is upwards bounced to return to the original state under the action of the elastic force of the first elastic resetting piece 21; and then the parking brake process of the next cycle can be realized by stepping on again.
The pedal parking brake device realizes parking brake and brake release only by stepping on the pedal 2, the parking brake is realized by stepping on once, the brake is released after stepping on again, the parking brake is realized quickly and simply by pedal operation, and the manual operation is not needed.
On the basis of the scheme, the rack 1 is rotatably provided with the rotary blocking piece 5, the rotary blocking piece 5 can rotate relative to the rack 1, and the rotating shaft of the rotary blocking piece 5 is parallel to the rotating shaft of the locking connecting rod 3.
The rear end of the rotary catch 5 exceeds the rear end of the lock fork 4, and when the pedal 2 is stepped on, the lock pin 31 contacts the upper edge of the rotary catch 5 firstly and can move to the upper edge of the lock fork 4 along the rotary catch 5, and the guide is provided by the lock fork 4 after being guided by the rotary catch 5. The rotating flap 5 is shown in an obtuse V-shaped configuration.
The third elastic reset piece 51 is arranged on the rotary barrier 5, and the third elastic reset piece 51 applies elastic force to the rotary barrier 5, so that the rear end of the rotary barrier 5 has a downward rotation tendency. The upper part of the front end of the rotary catch 5 is blocked and limited by the rotary catch 52, the rotary catch 52 shown in fig. 1 is arranged on the side wall of the lock fork 4, when the lock pin 31 contacts the rear end of the upper edge of the rotary catch 5, the front end of the rotary catch 5 is blocked by the rotary catch 52 and cannot rotate, the upper edge of the rotary catch 5 and the upper edge of the lock fork 4 are overlapped smoothly, and the lock pin 31 can smoothly transit to the lock fork 4 from the rotary catch 5.
Due to the arrangement of the rotary blocking piece 5, the transverse length of the lock fork 4 can be reduced, and the lock fork 4 is prevented from blocking the locking process of the lock pin 31; when the lock is released, the lock pin 31 passes under the lock fork 4 and contacts the rear end of the lower edge of the rotary catch 5 to resist the elastic force of the third elastic reset piece 51, so that the rotary catch 5 rotates counterclockwise, the lock pin 31 is separated from the rotary catch 5 when passing over the rearmost end of the lower edge of the rotary catch 5, the pedal plate 2 returns to the initial position, and the rotary catch 5 rotates clockwise under the elastic force of the third elastic reset piece 51 to contact the rotary catch pin 52 again.
The frame 1 is fixedly provided with a blocking block 11, the blocking block 11 is positioned at the front side of the clamping groove of the locking fork 4, and the blocking block 11 inclines towards the clamping groove to guide the locking pin 31 to be clamped in. When the treading amplitude of the pedal 2 is too large, the lock pin 31 exceeds the front end of the upper edge of the lock fork 4 more, and at the moment, the lock pin 31 contacts the upper surface of the blocking block 11, so that the lock pin 31 is prevented from directly falling below the lock fork 4 to cause the locking failure; since the rear end of the stopper 11 faces the engaging groove, the lock pin 31 moves backward along the stopper 11 when the pedal 2 is released, and it can be ensured that the lock pin 31 is accurately engaged in the engaging groove of the locking fork 4.
The fork 4 is spaced apart from the stop 11 by a distance which at least ensures that the locking pin 31 can pass through. As long as the rotation amplitude of the foot pedal 2 is such that the lock pin 31 goes over the front end of the upper edge of the lock fork 4, the subsequent successful locking must be ensured. The stop block 11 has the meaning of blocking and guiding, and in order to ensure the reliability of the device, the lock pin 31 is firstly contacted with the stop block 11, and after an operator releases the pedal 2, the lock pin is clamped into the clamping groove under the traction of the first elastic reset piece 21 and the second elastic reset piece 32 and the guiding of the stop block 11. The locking link 3 is used for limiting the limit position of the locking link 3 rotating downwards through a link stop pin 23 arranged on the pedal 2, and the second elastic resetting piece 32 pulls the locking link 3 to be pressed against the link stop pin 23 under the condition that the locking link 3 is not subjected to other external force.
Specifically, the first elastic restoring member 21, the second elastic restoring member 32 and the third elastic restoring member 51 of the present invention are springs, respectively; the rear end of the first elastic reset piece 21 is connected with the frame 1, and the front end is connected with the pedal 2; the rear end of the second elastic reset piece 32 is connected with the pedal 2, and the front end is connected with the locking connecting rod 3; the front end that third elasticity resets 51 is connected in the rear end of rotatory separation blade 5, and the rear end is connected in frame 1, when specifically setting up, can set up the connection claw in the side protrusion of the rear end of rotatory separation blade 5 side, and third elasticity resets 51 and installs in connecting the claw, can avoid third elasticity to reset 51 and hinder the lockpin 31 and remove. The pedal 2, the locking link 3 and the rotary catch 5 have a tendency to rotate respectively through the expansion spring.
On the basis of any technical scheme and mutual combination of the technical schemes, the brake sensor 6 is arranged on the frame 1, and the brake sensor 6 is positioned on the rear side of the pedal 2 and can be contacted with the brake sensor 6 in an initial state. When the pedal plate 2 leaves the initial position (the rebound limit position), the brake sensor 6 is triggered, a brake signal can be transmitted to the vehicle control unit, and the vehicle control unit can control the running system to stop working conveniently.
The invention can be used as a brake by controlling the treading amplitude of the pedal plate 2, when the lock pin 31 is positioned on the upper edge of the lock fork 4 to move, the speed reduction is realized by controlling the treading amplitude of the pedal plate 2, and when the lock pin 31 is clamped into the clamping groove of the lock fork 4, the parking is realized.
A limiting mechanism 7 is arranged between the frame 1 and the pedal plate 2, and the limiting mechanism 7 is used for limiting the limit position of the rotation of the pedal plate 2, the initial position of the pedal plate 2 and the limit position of the downward rotation.
Specifically, the limit mechanism 7 of the present invention includes a limit stopper 71 and a limit bolt 72. The limit bolt 72 is connected with the limit stopper 71 through threads, the limit bolt 72 and the limit stopper 71 are respectively arranged in the brake stroke direction and the rebound stroke direction of the pedal plate 2, and limit is realized by abutting against the pedal plate; the adjustment of the brake stroke range of the pedal plate can be realized by adjusting the fastening stroke of the limiting bolt.
