Technical Field

[0001] This utility model relates to the field of displacement sensor technology, specifically to a linear displacement monitoring device integrating multiple Hall effect sensors. Background Technology

[0002] Displacement sensors, also known as linear sensors, are a type of linear device that uses metal induction. The function of a sensor is to convert various measured physical quantities into electrical quantities. Displacement is a quantity related to the movement of an object's position during motion. Small displacements are usually detected using strain gauge, inductive, differential transformer, or eddy current sensors, while large displacements are often measured using sensing technologies such as inductive synchros, optical gratings, capacitive gratings, and magnetic gratings.

[0003] The above-mentioned technical conditions still have shortcomings: most existing displacement sensors only have one monitoring method when in use, and their effect on displacement data monitoring is not accurate enough, which is prone to errors and thus reduces the effectiveness of the displacement sensor.

[0004] Based on this, the present invention designs a linear displacement monitoring device integrating multiple Hall effect sensors to solve the above problems. Utility Model Content

A positioning base is disposed on one side of the connecting base, and a magnet is snapped onto the positioning base. The magnet is adapted to the Hall effect sensors on the circuit board.

[0007] By adopting the above technical solutions, the detection method of its Hall effect sensor can improve the accuracy of displacement monitoring, while the non-contact method can reduce wear during the monitoring process and increase its service life.

[0008] Preferably, the connecting seat has a cross groove, a cross positioning block is fixedly connected to the positioning seat, a locking groove is provided on the cross positioning block, and an installation groove communicating with the cross groove is provided inside the connecting seat.

[0013] By adopting the above technical solution, adhesive can be applied and then the magnets can be bonded.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0024] A linear displacement monitoring device integrating multiple Hall effect sensors includes a housing 1 and a connecting base 2. The connecting base 2 is disposed on the movable structure to be monitored, thereby enabling the monitoring of the movement of the movable structure. A circuit board 3 is disposed inside the housing 1, and multiple Hall effect sensors are disposed on the circuit board 3 to monitor the displacement of the movable structure in the length direction of the circuit board 3. A laser sensor 4 is disposed on the housing 1 and near the connecting base 2. A positioning base 7 is disposed on one side of the connecting base 2, and a magnet 8 is engaged with the positioning base 7. The magnet 8 is adapted to the Hall effect sensors on the circuit board 3. When the position of the magnet 8 changes, the Hall effect sensors on the circuit board 3 can emit a specified electrical signal.

[0025] Furthermore, a cross groove 9 is provided on the connecting seat 2, and a cross positioning block 10 is fixedly connected to the positioning seat 7. The cross positioning block 10 can be fully inserted into the cross groove 9. A locking groove 14 is provided on the cross positioning block 10, and an installation groove 15 communicating with the cross groove 9 is provided inside the connecting seat 2. By inserting a locking bolt into the installation groove 15, the cross positioning block 10 can be firmly locked inside the cross groove 9, thereby realizing the splicing of the positioning seat 7 and the connecting seat 2.

[0026] Furthermore, limit blocks 11 are fixedly connected to both sides of the inner wall of the positioning seat 7, and limit grooves 12 are opened at corresponding positions on the magnet 8, with the limit blocks 11 and limit grooves 12 being compatible.

[0027] Furthermore, an adhesive part 13 is provided on the inner side of the positioning base 7. An appropriate amount of glue is applied to the adhesive part 13 to securely install the magnet 8.

[0028] Furthermore, a data transmission line 5 is provided on the circuit board 3, which extends through the housing 1 to the outside of the housing 1, and one end of the data transmission line 5 is connected to a quick-release connector 6.

[0029] The implementation principle of this embodiment is as follows: During use, the positioning seat 7 is snapped onto the connecting seat 2 on the movable structure to be tested, so that the cross positioning block 10 is fully inserted into the cross groove 9, and then it is locked with bolts. Then, an appropriate amount of glue is applied to the adhesive part 13, and then the magnet 8 is installed on the positioning seat 7, so that the limiting block 11 enters the corresponding limiting groove 12. The magnet 8 is glued to the positioning seat 7. When performing displacement monitoring, the magnet 8 undergoes displacement changes in the magnetic field generated by the Hall sensor, changing the magnetic field state, thereby enabling the monitoring of the distance moved by the movable structure. At the same time, the laser sensor 4 is activated, which emits a monitoring beam. The monitoring beam is reflected back to the laser sensor 4, thereby also monitoring the displacement of the connecting seat 2, increasing the monitoring effect of the displacement sensor.
