Description

Technical Field

[0001] The utility model relates to the technical field of electronic equipment, in particular to a three-axis gyroscope. Background Art

[0002] A three-axis gyroscope is a precision sensor that can simultaneously measure an object's angular velocity in the X, Y, and Z directions. Its operating principle is based on the conservation of angular momentum and the Coriolis force, and it determines an object's motion by detecting changes in its angular velocity in each direction.

[0003] Basic three-axis gyroscopes are generally fixed by bolt installation. However, simple bolt and nut installation has the hidden danger of loosening or even detaching as the installation equipment moves and the use time passes, affecting the installation stability and measurement accuracy of the gyroscope. In order to solve the above technical problems, we designed a three-axis gyroscope. Utility Model Content

[0004] The purpose of the utility model is to provide a three-axis gyroscope with the advantage of anti-loosening protection, which solves the problem that the simple bolt and nut installation in the basic three-axis gyroscope may loosen or even fall off as the installation equipment moves and the use time passes, affecting the installation stability and measurement accuracy of the gyroscope.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a three-axis gyroscope, comprising a housing and a mounting substrate, an A / D converter fixedly mounted at the center of the housing surface, a control chip fixedly mounted at the center of the bottom of the housing, filters fixedly mounted on the surface of the housing and on both the front and rear sides of the control chip, a mounting screw fixedly connected to the right side of the housing, the right end of the mounting screw passing through the mounting substrate and being sleeved with an anti-slip locking assembly, the anti-slip locking assembly comprising a pressing nut and a wedge block, and a wedge block fixedly embedded on one side of the pressing nut.

[0006] Preferably, there are two pressing nuts, which are respectively located on the left and right sides of the mounting base.

[0007] Preferably, the pressing nut and the wedge block are both sleeved and mounted on the mounting screw, and the inner ring of the pressing nut is threadedly connected to the connection point of the mounting screw.

[0008] Preferably, the rubber ring is located between the pressing nut and the mounting base plate, and a through hole for use with the mounting screw is opened on the surface of the mounting base plate.

[0009] Preferably, there are four mounting screws, which are distributed at the four corners on the right side of the housing.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0011] The utility model has the advantage of anti-loosening protection by arranging the installation screw and the anti-slip locking component. The rubber ring can be installed between the pressure nut and the installation base plate, and the pressure nut is screwed in. The wedge block cooperates to squeeze the rubber ring, so that the rubber ring is elastically deformed and in close contact with the wedge block and the pressure nut. The elasticity of the wedge block itself is used to increase the friction force that the pressure nut needs to overcome when rotating, thereby achieving the effect of anti-loosening protection.

[0017] See also Figure 1-Figure 4 The three-axis gyroscope includes a housing 1 and a mounting substrate 6. An A / D converter 3 is fixedly mounted at the center of the surface of the housing 1. By setting the A / D converter 3, the analog signal detected by the gyroscope can be converted into a digital signal for subsequent digital circuit processing and transmission. A control chip 4 is fixedly mounted at the center of the bottom of the housing 1. Filters 5 are fixedly mounted on the surface of the housing 1 and on both sides of the front and back of the control chip 4. By setting the filter 5, it can reduce measurement errors and noise and improve the accuracy and stability of the signal. Generally speaking, the filter 5 can effectively remove high-frequency noise and drift error in the gyroscope signal, thereby improving the measurement accuracy. The right side of the housing 1 is fixedly connected to a mounting screw 2. The right end of the mounting screw 2 passes through the mounting base plate 6 and is sleeved with an anti-slip locking component 8. The anti-slip locking component 8 includes a pressing nut 801 and a wedge block 802. A wedge block 802 is fixedly embedded on one side of the pressing nut 801. By setting the wedge block 802, a protrusion and a groove can be formed. In the installed state, the contact area with the rubber ring 803 is increased, and the overall anti-slip and anti-loosening effect is better.

[0018] See also Figure 3 and Figure 4, the number of the pressing nuts 801 is two, and they are respectively located on the left and right sides of the mounting base 6;

[0019] See also Figure 3 and Figure 4 The pressing nut 801 and the wedge block 802 are both sleeved and installed on the mounting screw 2. By setting the rubber ring 803, they can produce elastic deformation when under pressure, which is used to increase the contact friction with the pressing nut 801 and prevent the pressing nut 801 from rotating at will. The inner ring of the pressing nut 801 is threadedly connected to the connection of the mounting screw 2. By setting the mounting screw 2 and the pressing nut 801, a threaded transmission effect can be achieved. When the pressing nut 801 is driven to rotate, the pressing nut 801 will also produce lateral displacement.

[0020] See also Figure 3 and Figure 4 The rubber ring 803 is located between the pressing nut 801 and the mounting base plate 6. The surface of the mounting base plate 6 is provided with a through hole 7 for use with the mounting screw 2. By providing the through hole 7, the mounting screw 2 can pass through the installation space requirement;

[0021] See also Figure 1 and Figure 3 , the number of mounting screws 2 is four, and they are distributed at the four corners on the right side of the housing 1;

[0022] The housing 1 is made of ABS plastic, which has high strength, high toughness, and good impact resistance. It also has good heat resistance, chemical stability, and processing performance. It is a material with excellent comprehensive performance and high cost-effectiveness.

[0023] The inner diameter of the through hole 7 is larger than the outer diameter of the mounting screw 2 , and the outer diameter of the rubber ring 803 is larger than the inner diameter of the through hole 7 .

[0024] When in use, all components are in the initial installation state. First, the wedge block 802 is threadedly sleeved on the mounting screw 2, and the rubber ring 803 is moved onto the mounting screw 2, and the shell 1 is moved. One end of the mounting screw 2 passes through the through hole 7 on the mounting base plate 6, so that the rubber ring 803 is placed between the mounting screw 2 and the mounting base plate 6. Then, on the other side of the mounting base plate 6, the rubber ring 803 is sleeved and the pressure nut 801 is screwed in in sequence. The two rubber rings 803 and the pressure nut 801 are symmetrically arranged on both sides of the mounting base plate 6. Then, with a special tool such as a wrench, the pressure nut 801 is driven to rotate further. Under the threaded transmission of the mounting screw 2, the direct distance between the pressure nut 801 and the mounting base plate 6 is reduced, and the rubber ring 803 is compressed. With the assistance of the wedge block 802, the contact area between the pressure nut 801 and the rubber ring 803 is effectively increased. The elastic performance of the rubber ring 803 is used to further increase the friction force that the pressure nut 801 needs to overcome when rotating, thereby achieving the purpose of anti-slip and anti-loosening protection.

[0025] In summary, the three-axis gyroscope solves the problem that the simple bolt and nut installation in the basic three-axis gyroscope, by providing the installation screw 2 and the anti-slip locking assembly 8, has the hidden danger of loosening or even detaching as the installation equipment moves and the use time passes, affecting the installation stability and measurement accuracy of the gyroscope.
