Description

Technical Field

[0002] Another name for a gyroscope is an angular velocity sensor. By definition, a gyroscope is a sensor that measures the angular motion or angular velocity of a carrier. The external leads of a quartz micromechanical gyroscope are led out through the lead-out holes on the cover, and the lead-out holes are sealed with glue. However, the sealing effect is poor, and no anti-collision protection can be provided during use.

[0003] According to the quartz micro-mechanical gyroscope disclosed in the patent document with the existing publication number CN114993279A, it includes a gyro flange, a vibration damping body, a first cover body and a second cover body, wherein the vibration damping body is arranged in the gyro flange, and the first cover body and the second cover body are respectively encapsulated at the two ends of the gyro flange; a quartz micro-mechanical gyroscope core is arranged in the vibration damping body; a gyro data acquisition and processing circuit board is arranged in the gyro flange and connected to the quartz micro-mechanical gyroscope core, and when the technical solution is used, it is led out to the outside of the gyroscope through the outlet hole on the cover body, and the position of the outlet hole is sealed by glue. The structural improvement can improve the sealing of the installation space of the gyro data acquisition and processing circuit board, and avoid the quartz micro-mechanical gyroscope from gathering water vapor inside due to poor sealing, so as to affect the working performance of the gyro data acquisition and processing circuit board. With respect to the above technical solution, although the solution avoids the entry of water vapor, once the device collides during use, the device cannot perform displacement buffering, and the device is easily damaged under collision, which is inconvenient during use.

[0010] Furthermore, one end of the support mechanism is fixed on the connecting seat, and a sealing gasket is installed between the connecting seat and the mounting hole.

DETAILED DESCRIPTION

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] See also Figures 1 to 4 The utility model provides a technical solution: a quartz micromechanical gyroscope, comprising a gyroscope body, the gyroscope body comprising a fixed seat 1, a fixed box 2 is fixed on the top of the fixed seat 1, a movable plate 3 is movably installed on the fixed box 2, the movable plate 3 is installed on the fixed box 2 through a fixing mechanism 4, a connecting seat 5 is movably installed on the bottom of the fixed seat 1, a movable seat 6 is fixed on the bottom of the connecting seat 5, a fixing groove 7 is opened on the movable seat 6, a wire 8 is movably installed inside the fixing groove 7, a fixing hole 9 is opened between the fixed box 2 and the fixed seat 1, an arc-shaped electrode sheet 10 is fixed on the inner wall of the fixing hole 9, an electrode column 11 is movably installed inside the fixing hole 9, the electrode column 11 cooperates with the arc-shaped electrode sheet 10, the arc-shaped electrode sheet 10 is respectively at different positions of the fixing hole 9, and the arc-shaped electrode sheets 10 at different positions are connected and cooperated with the electrode column 11 under the movement of the electrode column 11 in the later stage.

[0021] In this embodiment, a support seat 20 is fixed to one end of the electrode column 11, a fixing plate 12 is fixed to the top of the support seat 20, a circuit board is fixedly installed inside the fixing plate 12, one end of the electrode column 11 is fixedly installed on the circuit board, a connecting hole 18 is opened on the support seat 20, a rubber plate 19 is fixed to the side of the fixing plate 12, a limit ring 13 is movably installed on the side of the rubber plate 19, the limit ring 13 is fixed on the inner wall of the fixing seat 1, a mounting hole 16 is opened inside the fixing seat 1, a ring groove 17 is opened on the inner wall of the mounting hole 16, a ring seat 14 is rotatably installed inside the ring groove 17, a supporting mechanism 15 is fixed on the ring seat 14, one end of the supporting mechanism 15 is fixed on the connecting seat 5, a sealing gasket is installed between the connecting seat 5 and the mounting hole 16, the supporting mechanism 15 is a supporting spring, the supporting spring provides the required space for the movement of the connecting seat 5, and after the movable seat 6 is contracted inside the mounting hole 16, the fixed seat 1 can move downward for buffering at a later stage.

[0022] The device provides the required power for the electrical appliances inside the device through an external power supply. When the device is used, the support seat 20 is first fixedly installed in the use position through the connecting hole 18. After the support seat 20 is fixed, the fixing seat 1 is installed on the support seat 20 through the movable seat 6, and the fixing hole 9 on the fixing seat 1 is installed on the electrode column 11. The arc-shaped electrode sheet 10 inside the fixing hole 9 is in contact and squeezed with the electrode column 11, and the arc-shaped electrode sheet 10 is squeezed and deformed, so that the arc-shaped electrode sheet 10 is always connected to the electrode column 11. After the arc-shaped electrode sheet 10 and the electrode column 11 are connected, the circuit connection is realized. The limiting ring 13 contacts the rubber plate 19 on the side of the fixing plate 12. After the limiting ring 13 contacts the rubber plate 19, it applies an extrusion force to the rubber plate 19. The rubber plate 19 is deformed after being squeezed, and the deformation causes the limiting ring 13 and the rubber plate 19 to deform. The rubber plate 19 is annular, and the annular rubber plate 19 and the limit ring 13 cooperate to complete a comprehensive seal. Later, when the fixed box 2 is subjected to a collision force, the fixed seat 1 moves to one side of the movable seat 6, and the connecting seat 5 moves inside the mounting hole 16, and the movement provides a buffer displacement force for the fixed box 2. When the fixed seat 1 moves, the limit ring 13 moves on the rubber plate 19. When moving, the rubber plate 19 generates resistance for the limit ring 13, and the resistance facilitates the limit ring 13 to slowly move back to its position on the rubber plate 19 later. When the electronic components or circuit boards inside the fixed box 2 are damaged, the fixed seat 1 is moved upward, and the arc-shaped electrode sheet 10 inside the fixing hole 9 is separated from the electrode column 11. After separation, the fixed seat 1 and the support seat 20 are separated. The separation facilitates the replacement of unidirectional equipment, effectively reducing the waste of resources and the increase in maintenance costs.
