Embodiment Construction

[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

[0028] Such as Figure 1-4 As shown, the present invention provides a motor linkage braking mechanism, including: a motor 1, a brake disc 2, a first rotating shaft 3, a brake lever 4, a brake pad 5, a spring 6, a power switch 7, a second rotating shaft 8, and a trigger lever 9. The brake disc 2 is fixed on the motor 1 and rotates together with the motor 1; the brake pad 5 is fixed on the brake lever 4, and the brake lever 4 rotates around the rotating shaft 3, and when it rotates to a certain position, the brake pad 5 contacts the brake disc 2 to realize braking; the spring 6 It is fixed on the brake lever 4 to ensure that the brake lever 4 is subjected to a downward force; the trigger lever 9 is connected to the brake lever 4 through the rotating shaft 8, and the up and dow...

Abstract

The invention discloses a linkage brake mechanism for a motor. The linkage brake mechanism comprises the motor, a brake disc, a first rotating shaft, a second rotating shaft, a brake rod, a brake pad, a spring, a power switch and a touch rod; the brake disc and the motor can rotate together, the brake pad is fixed to the brake rod, the brake rod can rotate around the first rotating shaft, and the brake pad touches the brake disc to brake when the brake rod rotates to a certain position; the spring is fixed to the brake rod and can guarantee that the brake rod is stressed by downward acting force; the touch rod is connected with the brake rod through the rotating shafts, and the touch rod can move up and down to drive the brake rod to rotate. In shutdown, the motor can quickly stop rotating through the brake pad. The linkage brake mechanism comprises the power switch, the brake mechanism does not work when the power switch is turned on, and the brake mechanism works when the brake mechanism is turned off, so that the motor can stop rotating in a short time. The linkage brake mechanism solves the technical problems that a motor brake mechanism is complex in structure and low in reliability.

Description

technical field [0001] The invention relates to a brake system of a motor, more specifically, the invention relates to a linkage brake mechanism of a motor. Background technique [0002] Electric tools, especially garden tools, require the whole machine to have a braking function to ensure that the operator will not be injured. Therefore, it is necessary to design a structure so that the motor can stop rotating quickly. [0003] With the improvement of living standards, people have higher and higher requirements for the greening level of living and living, and the large-scale ecological green spaces, residential green spaces, and road green spaces in cities continue to increase. Therefore, various garden tools are also continuously introduced. There are many defects in the mechanical brake mechanism of the tool, such as: the brake fails; the switch trigger is laborious to operate; the internal structure is not compact enough, resulting in a large and bulky appearance; Time ...
