Description

Accelerometer

Technical Field

The utility model relates to the field of sensors, in particular to an acceleration sensor.

Background technique

An accelerometer is a device that senses changes in an object's acceleration and converts it into an electrical signal. Accelerometers, combined with other sensors (gyroscopes, etc.) and related algorithms, can be used to sense conditions related to the movement of an object, including acceleration, inclination, vibration, and motion pattern recognition. They are widely used in mechanical, aerospace, and civil engineering structural vibration testing and long-term vibration monitoring.

When using an accelerometer to measure the vibration response of a structure (i.e., measuring acceleration), the change in voltage under different vibrations of the MEMS micro-electromechanical system is used to measure the change in acceleration, and finally the analog-to-digital signal is output. The final test result is transmitted to the cloud platform for display via wireless transmission. When measuring, the accelerometer is specifically installed on an external plane. However, when the sensor leaves the factory, it is based on an ideal horizontal plane in order to suit the public. However, the plane we use during installation is not necessarily an ideal plane, so we need to adjust the external plane level ourselves.

The existing acceleration sensor is not convenient for adjusting the angle of the sensor body itself, and therefore, is not convenient for measurement when the external plane on which the acceleration sensor is installed is an inclined plane.

1 to 3 , the present invention discloses an acceleration sensor according to an embodiment of the present invention, including an adjustment fitting 220 and an adjustment member 240 located below a sensor body 100 .

The adjusting member 240 matches with the adjusting fitting member 220 , and an adjusting hole 222 is provided on the adjusting fitting member 220 . The adjusting member 240 includes an adjusting column 242 that matches with the adjusting hole 222 , thereby supporting the sensor body 100 . The length of the adjusting column 242 inserted into the adjusting hole 222 is adjusted, thereby adjusting the angle of the sensor body 100 .

Specifically, the adjustment structure 200 includes an adjustment piece 240 and an adjustment fitting piece 220. The adjustment fitting piece 220 is located at the bottom of the sensor body 100. The adjustment piece 240 matches the adjustment fitting piece 220. Specifically, the adjustment fitting piece 220 has an adjustment hole 222. The adjustment piece 240 includes an adjustment column 242. The adjustment column 242 can be inserted into the adjustment hole 222 and fixed in the adjustment hole 222. The staff can adjust the length of the adjustment column 242 inserted into the adjustment hole 222 to adjust the length of the adjustment column 242 outside the adjustment hole 222, thereby adjusting the angle of the sensor body 100.

The sensor body 100 can be placed on any external plane that needs to be measured, and connected to the adjustment fitting 220 through the adjustment piece 240, and the length of the adjustment column 242 extending into the adjustment hole 222 can be adjusted, so that the length of the adjustment piece 240 outside the adjustment hole 222 can be adjusted, and finally the inclination angle of the sensor body 100 can be adjusted. Therefore, the sensor body 100 can also be placed horizontally on an inclined plane, thereby facilitating the operation of the acceleration sensor.

2 and 3 , further, the adjusting column 242 is threadedly connected to the adjusting hole 222 .

2 , further, the bottom surface of the sensor body 100 is rectangular.

Specifically, the bottom surface of the sensor body 100 is square, the adjusting column 242 is provided with an external thread, the adjusting hole 222 is provided with an internal thread, and the adjusting column 242 and the adjusting hole 222 are threadedly connected to facilitate adjusting the length of the adjusting column 242 extending into the adjusting hole 222.

2 , there are two adjusting fittings 220 , each of which is connected to an adjusting piece 240 , and the two adjusting fittings 220 are located on the same side of the rectangle, and the two adjusting fittings 220 are located at the corners of the rectangle.

Specifically, when there are two adjustment fittings 220, the two adjustment fittings 220 are located on the same side of the rectangle and at the corners of the rectangle, and the adjustment pieces 240 are threadedly connected to the adjustment fittings 220 in a one-to-one correspondence. Therefore, the lengths of the two adjustment posts 242 extending into the adjustment holes 222 are adjusted to be the same, and the lengths of the two adjustment posts 242 outside the adjustment holes 222 are also the same, and the angle of the sensor body 100 can also be adjusted.

2 , there are three adjusting fittings 220 , and another adjusting fitting 220 is located in the middle of another side of the rectangle, which is opposite to the side where the two adjusting fittings 220 are located.

Specifically, when there are three adjusting fittings 220 and three adjusting fittings 240, two adjusting fittings 220 are located on the same side of the rectangle and at the corner of the rectangle, while another adjusting fitting 220 is located on the side opposite to the side where the two adjusting fittings 220 are located and is located in the middle of the side plate next to the side. Therefore, the arrangement of the three adjusting fittings 220 can be adjusted in three ways: only the extension length of the adjusting columns 242 corresponding to the two adjusting fittings 220 located on the same side can be adjusted, and the extension length can be kept consistent; only the extension length of the adjusting column 242 corresponding to one adjusting fitting 220 located on the opposite side can be adjusted; and the extension length of the adjusting columns 242 corresponding to the three fittings can also be adjusted.

In one embodiment, the adjusting fitting 220 located in the middle of the side is fixedly connected to the adjusting member 240 , and the other two adjusting members 240 can adjust the length in the adjusting hole 222 .

Specifically, one of the adjustment methods is: only adjust the length of the adjustment hole 222 into which the adjustment columns 242 corresponding to the two adjustment fittings 220 located on the same side extend, and keep the extending lengths consistent.

In another embodiment, the three adjustment members 240 can all adjust the length within the adjustment hole 222 .

Specifically, the lengths of the adjustment posts 242 corresponding to the three matching pieces extending into the adjustment holes 222 are adjusted.

In another embodiment, there are four adjusting fittings 220 , each of which is connected to an adjusting piece 240 , and the four adjusting fittings 220 are located at four corners of the sensor body 100 .

Specifically, the number of the adjustment fittings 220 may also be four, and the four adjustment fittings 220 are all located at the four corners of the bottom rectangle of the sensor body 100 .

In a specific implementation process, it is only necessary to place the sensor body 100 stably on an inclined plane, and to keep the sensor body 100 horizontally placed by adjusting the adjusting member 240 and the adjusting fitting member 220 .

1 , specifically, the sensor body 100 is connected with a signal transmission component 140 and a horizontal display component 120. The signal transmission component 140 is used to transmit signals. The test results are transmitted to the cloud platform for display via the signal transmission component 140 and wirelessly transmitted. When the sensor body 100 is adjusted to a horizontal position, the test results are displayed via the horizontal display component 120.

The sensor body 100 includes a shell 114 and an upper cover 112 , and the shell 114 and the upper cover 112 are detachable. The adjustment fitting 220 and the adjustment hole 222 are both arranged at the bottom of the shell 114 of the sensor body 100 , and the horizontal display member 120 is arranged through the upper cover 112 .

3 , the adjusting member 240 further includes a supporting portion 244 connected to the adjusting column 242 . The supporting portion 244 is located at one end of the adjusting column 242 away from the sensor body 100 . The adjusting column 242 is inserted into the adjusting hole 222 . The supporting portion 244 contacts the outside to support the sensor body 100 .

Furthermore, the support portion 244 is disc-shaped, and an outer ring of the support portion 244 is provided with anti-slip grooves for facilitating twisting of the support portion 244 .

Specifically, the adjusting member 240 includes an adjusting column 242 and a supporting portion 244 . The adjusting column 242 is used to extend into the adjusting hole 222 , and the supporting portion 244 is used to contact with the outside, specifically with the surface to be measured, to support the sensor body 100 .

The disc shape facilitates stable support, while the anti-slip pattern facilitates turning the adjustment member 240 to adjust the length of the adjustment column 242 extending into the adjustment hole 222 .

In summary, when a traditional acceleration sensor is placed on an inclined external plane for operation, the acceleration sensor cannot be adjusted to be horizontal, and the external plane needs to be adjusted to be horizontal, which is inconvenient to operate. In this embodiment, the inclination angle of the sensor body 100 can be adjusted by setting the adjustment member 240 and the adjustment fitting member 220, so that the sensor body 100 can be adjusted to be horizontal on any plane.

The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent application. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
