Electric mower with motor protection device

Abstract

The invention provides an electric mower with a motor protection device, which comprises an operating lever; a battery box for loading batteries is arranged on one end of the operating lever and a motor seat is arranged on the other end; a handle is arranged on the operating lever; a motor is arranged in the motor seat and electrically connected with the battery; the motor is provided with a rotating shaft; a weeder which is arranged on an end of the rotating shaft of the motor rotates with the motor; a motor protection device arranged between the weeder and the rotating shaft bears action force, when the weeder is affected by beating or external force, thereby allowing the rotating shaft not to directly bear the force, reducing loss and achieving the effect of protecting the motor.

Description

technical field [0001] The invention relates to an electric lawnmower, in particular to a motor protection device for the electric lawnmower. Background technique [0002] With the development and progress of science and technology, people's requirements for things have changed from the old thinking that can be used to become quite delicate and demanding. Only the idea of ​​continuous improvement or innovation will produce new forms to increase the added value of products. , in order to survive under the test of fierce market competition. [0003] The attached reference is Japanese Utility Model Publication No. 7-5321 patent case, which discloses a portable electric lawn mower 1, which mainly improves the environmental protection problems of engine-type lawn mower noise and black smoke emission. The use of medium and low vibration issues effectively provides user operability. [0004] However, no matter the aforementioned mower 1 uses metal blades or nylon rope 6 as the mo...

AI Technical Summary

Problems solved by technology

[0004] However, no matter whether the aforementioned lawn mower 1 uses metal blades or nylon rope 6 as the lawn mower, because the motor 5A does not have any protection device, it is easy to accidentally touch stones during the mowing work, causing the main shaft of the motor 5A to be touched. Affect the actual working efficiency, relatively increase the load of the motor 5A, and there is a risk of shortening the service life

Wherein, if the lawn mower 1 has adopted the nylon rope 6 as the mower, the user often directly hits the button (not shown in the figure) on the mowing disc 7 and then pulls the nylon rope 6, so that the beating force will be directly transmitted As for the main shaft of the motor 5A, of course, as mentioned above, it is easy to greatly reduce the life of the motor 5A, so it is necessary to develop and improve it.
