Abstract

A mower brake structure comprises a base (1). A motor (7) is fixed on the base (1), and the base (1) is rotatablely connected to an output shaft (41). A belt pulley (2) is disposed on the output shaft (41), and the output shaft (41) is driven by the motor (7) through a belt. A belt pulley liner (4) is disposed between the belt pulley (2) and the output shaft (41). The belt pulley liner (4) is fixed with the output shaft (41). A locking structure is disposed between the belt pulley (2) and the belt pulley liner (4). The locking structure enables the rotating belt pulley (2) to drive the belt pulley liner (4) to rotate. A spring (5) is disposed between the belt pulley (2) and the belt pulley liner (4). A friction structure is further disposed between the belt pulley (2) and the belt pulley liner (4). After the belt pulley (2) loses power, the spring (5) releases the elasticity so that the belt pulley liner (4) rotates reversely relative to the belt pulley (2), and the friction structure works. The belt pulley (2) and the belt pulley liner (4) can rotate relatively for certain displacement. During the rotation process, a protruding portion at an inner side of the belt pulley (2) provides pressure to or releases pressure from a movable friction block (3) assembled on the belt pulley liner (4), thereby effectively ensuring the reliable running of the brake structure. Therefore, the brake structure is compact and easy to operate, and the system is stable and reliable.

Description

technical field [0001] The invention relates to a braking device for a lawnmower. Background technique [0002] A lawn mower is a commonly used garden tool suitable for trimming grass. However, due to structural reasons, the mechanical braking structure of the existing lawnmower is unstable and has the disadvantages of large fluctuations in braking time. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a brake structure of a lawn mower with simple structure, low cost, reliable and stable brake. [0004] In order to solve the above-mentioned technical problems, the present invention adopts the following technical solutions: the mower brake structure includes a base, a motor is fixed on the base and an output shaft is connected in rotation, and the output shaft is provided with a belt pulley and the motor through belt transmission, It is characterized in that: a pulley lining is provided between the pulley and the...
