Description

Technical Field

[0001] This utility model belongs to the field of tooling technology, specifically relating to a manual rotational impact testing tooling for MEMS inertial products. Background Technology

[0002] With the rapid development of MEMS inertial devices, MEMS inertial products are widely used in military and civilian fields such as automotive, robotics, consumer electronics, aerospace, and missile guidance due to their small size, low power consumption, low cost, light weight, wide dynamic range, and fast response speed. However, MEMS inertial devices are inevitably used in various harsh working environments, leading to significant reliability issues. During manufacturing, installation, transportation, or use, MEMS inertial devices are frequently subjected to severe shocks or vibration stresses. These harsh environmental stresses can cause changes or failures in some performance characteristics of MEMS inertial devices, resulting in typical failure modes including fracture, delamination, adhesion, fatigue, corrosion, and particulate contamination. MEMS inertial devices are typically used on rotating objects, requiring continuous monitoring of the object's motion under vibration and shock conditions. Traditional test fixtures often only allow for vibration or shock testing in a single direction, failing to meet the testing requirements of MEMS inertial devices in rotating working environments.

[0018] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly or indirectly attached to that other component. When a component is referred to as being "connected to" another component, it can be directly or indirectly connected to that other component.

[0020] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0022] This invention provides a manual rotational impact testing fixture for MEMS inertial products, such as... Figure 1-3 As shown, it includes: a bracket 1, a rotating rod 2 passing through the bracket 1 and rotatably connected to the bracket 1, one end of the rotating rod 2 being inserted into the mounting hole 4 at one end of the fixed base 3, the other end of the rotating rod 2 being provided with a handle 5, a locking screw 6 being provided on the side wall of the fixed base 3, and a base 7 being provided at the other end of the fixed base 3, with bolt holes 8 provided on the base 7.

[0023] A base 9 is provided at the bottom of the bracket 1 to provide stable support. The rotating rod 2 is mounted on the bracket 1 via a bearing 10 to reduce friction between components. The handle 5 is L-shaped for easy gripping and rotation. The corners of the rotating rod 2 are rounded to prevent injury to the user. The base 7 is disc-shaped, with three evenly spaced bases evenly spaced along its circumference. The MEMS inertial product 11 to be tested is stably fixed to the base 7 by multiple bolts.

[0024] The beneficial technical effects of the above technical solution are as follows: The MEMS inertial product 11 to be tested is fixedly installed on the base 7 with three bolts, and the rotating rod 2 is fixed in the mounting hole 4 of the fixed seat 3 with locking screws 6. After the MEMS inertial product 11 is powered on, product data is recorded. While manually rotating the handle 5 to rotate the rotating rod 2, the rotating rod 2 is struck with a metal rod. The impact magnitude and the impact on product performance are analyzed through product data. This fixture has a simple structure, and the base can meet the rapid installation of inertial products with different models and sizes of interfaces. It simulates the impact scenario of MEMS inertial products during rotation, thus improving the testing efficiency.
