Pedal parking braking device and mower

Abstract

The invention discloses a pedal parking braking device and a mower, which are applied to the field of braking, a pedal is hinged to a rack, the pedal can rotate downwards when being treaded down to drive an inhaul cable mechanism to realize parking braking, and the pedal restores to the original position under the elastic force action of a first elastic reset piece after being released; one end of the locking connecting rod is hinged to the pedal, the other end of the locking connecting rod is provided with a lock pin, when the pedal rotates downwards, the locking connecting rod is driven to move, the lock pin can move along the upper edge of the lock fork and is clamped into the clamping groove, and parking braking is achieved; when the pedal plate is treaded again, the pedal plate rotates downwards under the elastic action of the second elastic reset piece, the lock pin moves out of the clamping groove, moves below the lock fork and resets under the action of the second elastic reset piece, and meanwhile the pedal plate resets under the action of the first elastic reset piece and can be treaded again. Parking braking and braking releasing can be achieved only by treading the pedal, and parking braking can be achieved quickly, easily and conveniently through pedal operation without the help of hand operation.

Description

technical field [0001] The invention relates to the braking field, and further relates to a pedal parking brake device. Furthermore, the invention also relates to a lawnmower. Background technique [0002] For zero-turn or riding lawn mowers, traditional braking and debraking are done manually, and the manual driving lever is used to achieve braking deceleration, and then a traditional parking brake (such as a car handbrake mechanism) is used. Realize parking brake, brake deceleration, parking and release of parking all need the driver to use different handles to complete the operation, and the release of parking requires the decomposition of the hand (press the unlock switch with your fingers first, and then use the arm to pull the button). move the operating lever to perform the action of releasing the parking), the whole braking process needs to change the operating parts (from the driving operating lever or the steering wheel to the parking brake operating lever) and th...

Problems solved by technology

[0002] For zero-turn or riding lawn mowers, traditional braking and release of the brakes are done manually, using the manual travel lever to achieve braking deceleration, Then use the parking brake of the traditional structure (such as the mechanism of the car hand brake) to realize the parking brake. The braking deceleration, parking and releasing the parking action all need the driver to use different handles to complete the hand operation, and the release of the parking requires the hand The decomposition action (press the unlock switch with your fingers first, and then pull the operating lever with your arm to release the parking action), the entire braking process needs to change the operating parts (from the driving operating lever or steering wheel to the parking brake operating lever) upper) and hand position, which is cumbersome and labor-intensive. In an emergency, the driver needs to greatly change the hand movement to achieve braking, which has the disadvantages of long reaction time, long operating distance and easy misoperation, which is not conducive to rapid braking in emergency situations.
