Mechanical overload protection device, speed reduction mechanism and electrically-driven flip driver

Abstract

The invention discloses a mechanical overload protection device. The mechanical overload protection device comprises a power disc of a round structure and an overload protection disc, wherein the power disc is provided with a structure piece in power connection with the outside, one side surface of the power disc is provided with a round containing cavity, and the inner wall of the containing cavity is in a continuous closed sinusoid shape; the overload protection disc is used for being connected with the power disc and provided with an arc avoiding groove, and an elastic overload deformationpart is formed between the outer arc surface of the arc avoiding groove and the outer periphery of the overload protection disc; flanges are uniformly distributed in the middle of the outer peripheralwall of the elastic overload deformation part and are consistent with wave troughs of the sinusoid of the inner wall of the containing cavity in shape; one side of the overload protection disc is provided with a power output component; and the overload protection disc is put in the containing cavity of the power disc, and the flanges are located in the wave troughs of the inner wall of the containing cavity. The invention further discloses a speed reduction mechanism and an electrically-driven flip driver. The mechanical overload protection device, the speed reduction mechanism and the electrically-driven flip driver have the characteristics of being small in size, low in weight, high in bearing capacity, long in service life, stable in operation, low in noise and safe in performance, andthe product using safety is greatly improved.

Description

technical field [0001] The invention belongs to the field of smart home furnishing, and in particular relates to a mechanical overload protection device, a deceleration mechanism and an electric flip cover driver. Background technique [0002] With the development of the economy and the improvement of people's living standards, people's requirements for bathroom appliances and even household appliances are getting higher and higher, and intelligent and automated products are becoming more and more popular in today's market. Therefore, the intelligent automation of smart toilets, smart dishwashers, sinks, and washing machines is getting higher and higher today, and the automatic flip function is one of the functions of smart toilets, smart dishwashers, smart sinks, and smart washing machines. One of the manifestations. [0003] There are quite a few electrically-driven flip drivers with drive covers on the market today. The existing electric-driven flip drivers mainly includ...

Problems solved by technology

[0003] There are quite a few electrically-driven flip drivers with drive covers on the market today. The existing electric-driven flip drivers mainly include a motor, a reduction mechanism, and an actuator. In actual use, if the load of the device is too large (that is, when the rotational force of the driven part is too large), the DC motor will stall, which will increase the internal torque of the device and cause the driver to fail. , can no longer be used normally

[0004] In the prior art, in order to solve this problem, electronic components are generally used for overload protection, such as thermal relays for overload protection; however, since the above-mentioned products are applied in the presence of water, electronic components are easy to be damaged; for this purpose, a A mechanical overload protection device with low friction, low noise, stable operation and long service life
