Embodiment Construction

[0046] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0047] In the present disclosure, unless stated otherwise, the orientation words used such as "inner" and "outer" refer to the contours of the corresponding components. Specifically, refer to figure 1 , when the support beam 20 swings toward the first induction beam 41 or the second induction beam 42, it swings outward; "front" and "rear" are definitions for convenience of description, specifically, refer to figure 1 In the shown support beam 20, one end connected to the first base column 10 is the rear end, and one end connected to the mass block 30 is the front end. The terms "first", "second", and the like used in the present disclosure are for distinguis...

Abstract

The invention relates to an angular acceleration switch and a switch assembly. The angular acceleration switch comprises a first foundation pillar (10), a supporting beam (20), a mass block (30) and first induction beams (41), wherein the supporting beam (20) is connected to the first foundation pillar (10) in a swinging manner; the mass block (30) is fixed to the free end of the supporting beam (20), and a first magnetic film (31) is arranged on one side of the mass block (30) in the swinging direction; the first induction beams (41) are connected to the first foundation pillar (10) and arranged on one side of the supporting beam (20) in the swinging direction at intervals, and each first induction beam (41) is provided with a third magnetic film (411). The angular acceleration switch isclosed when the first magnetic film (31) and the third magnetic film (411) are attracted. Namely, the angular acceleration switch provided by the invention can realize a closing function by directly acquiring the angular acceleration.

Description

technical field [0001] The present disclosure relates to the technical field of sensors, in particular, to an angular acceleration switch and a switch assembly. Background technique [0002] The angular acceleration switch is an inertial sensor, its function is to close when the angular acceleration of the rotating object reaches a certain threshold, and keep the open state when the angular acceleration does not reach the threshold. In related technologies, the angular acceleration switch usually realizes its function by means of the linear acceleration switch. Specifically, the angular acceleration is obtained by detecting the linear acceleration of the object and converting it with the radius of rotation. Control the action of the switch, resulting in low precision of the switch. Contents of the invention [0003] An object of the present disclosure is to provide an angular acceleration switch to solve the problem of low structural accuracy of obtaining angular accelera...
