Problems solved by technology

Anti-collision security and secure braking, mowing and mowing are optional, and there are wires and a large area. These are easier said than done, and they have always been a long-standing problem with electric lawn mowers.
[0007]Why use a cord reel? Because of the long wires scattered on the ground, when the electric lawn mower mows back and forth, sometimes it is accidentally stepped on by feet or crushed by wheels, which affects safety; If the wire is not long enough, mowing is suspended, or the wire is managed manually, which increases safety hazards
Why put a cord reel on an electric lawn mower?

Embodiment Construction

[0077] Build the computer 3D model first, then engrave the mold; then add anti-collision and brakes to the lawn mower. The technical equation and modeling method are: use PRO / ENGINEER WILDFIRE drawing software, create a new working directory, create new parts, and sketch 2 pieces concentric circles. Open the variable section sweep (Var Sect Sweep) command, select the above 2 circles as the sweep trajectory and the reference trajectory. Draw a straight line parallel to the plane of 2 circles, the length L=(D-d) / 2, and the projection line corresponding to the edge of the circle. Establish parameter (PARAMETER) 1: C is a real number (real number), which can be assigned a value between 0.01-1 according to specific working conditions, such as 0.3; C is also called wave height. Establish parameter (PARAMETER) 2: N integer (integer), select a value between 2-100 according to specific working conditions, such as 13; N is also called wave number. Establish relation (RELATION), be as ...

Abstract

A series motor electric mower with a chassis anti-colliding protector and a function wave disc brake comprises the anti-colliding protector arranged on the front portion of a mower chassis, the brake arranged in the middle of the mower chassis, a grass beating head and a winder. When outer covering rubber skin of a movable support is collided at the front so that a sliding rod of the movable support is retracted, a limit switch is triggered so as to resist collision. The function wave disc brake comprises uneven disc pieces fluctuating according to wave-shape heights so as to be favorable for braking in alternate tension with relaxation, and parameters of the function wave disc brake are formed by computer molding. The brake is further provided with an axial shaft disc of a friction block gradually lifted according to functions, a belt pulley and a radial centrifugal throwing block, wherein the belt pulley is provided with internal multiple inner teeth, and the radial centrifugal throwing block is provided with multiple arc-shaped teeth. The series motor electric mower has the advantages that the anti-colliding safety and braking effect are reinforced, mowing and grass beating are selectable, and a moving area is large.

Description

technical field [0001] The invention relates to a lawn mower used for mowing lawns in gardens, parks, roads and other places. The anti-collision safety device at the front of the lawn mower chassis, and the series-excited motor electric lawn mower with a function wave disc brake in the middle of the lawn mower chassis; the series excitation with a chassis anti-collision safety belt and a function wave disc brake Motor-powered lawn mowers, or series motors with both trimmers and reels, including a bumper in the front of the mower chassis and a brake in the middle of the mower chassis Electric lawn mower. Background technique [0002] Lawn mowers are widely used to mow grass in the manner chosen by people. When some pedestrians like and are used to using lawn mowers, they put a little more force on the rear upper armrest and have a feeling of leaning and pressing down, which virtually increases the possibility of the front wheels being tilted and suspended. ; and the design...
