Description

Technical Field

[0001] This utility model relates to the field of sensor technology, and in particular to an anti-interference Hall sensor suitable for complex environments. Background Technology

[0002] A Hall sensor is a magnetic sensor based on the Hall effect that can convert magnetic field signals into electrical signals. It has wide applications in many fields such as industry, automobiles, and electronics. Hall sensors are divided into different types according to their needs, including closed-loop Hall sensors. Closed-loop (zero flux) Hall sensors use the Hall effect to detect magnetic fields. When the current being measured passes through the primary winding of the sensor, a magnetic field is generated in the magnetic core. After the Hall element detects this magnetic field, it generates a Hall voltage that is proportional to the magnetic field strength. This Hall voltage is amplified and converted by the signal processing circuit, and then outputs a DC voltage signal that is proportional to the measured current.

[0003] After the wires are installed inside the closed-loop Hall sensor, the environment in which the Hall sensor is installed is greatly affected by vibration. Therefore, under long-term vibration, the installed wires are prone to change position. After the wires are offset, they can easily affect the measurement accuracy of the closed-loop Hall sensor. Therefore, this application proposes an anti-interference Hall sensor suitable for complex environments. Utility Model Content

[0004] The purpose of this invention is to address the problem in the background art that vibration in the environment can affect the detection data of Hall sensors, and to propose an anti-interference Hall sensor suitable for complex environments.

[0005] The technical solution of this utility model is as follows: An anti-interference Hall sensor suitable for complex environments includes a base, a sensor body fixedly connected to the top of the base, a connecting block fixedly connected to one side of the sensor body, a mounting ring fixedly connected to one side of the connecting block, and a mounting plate fixedly connected to the side of the mounting ring away from the sensor body. Two sets of mounting plates are provided and symmetrically distributed. The outer walls of the two sets of mounting plates are fixedly connected by a connecting plate. A limiting sleeve is fixedly connected to one side of one set of mounting rings. A rack is slidably connected to the inner wall of the limiting sleeve. An arc-shaped plate is fixedly connected to the bottom of the rack. A gear is rotatably connected to one side of the sensor body, and the gear meshes with one side of the rack. Limit blocks are rotatably connected to the inner walls of the two sets of mounting rings. A toothed ring is fixedly connected to the inner wall of the limiting block, and the toothed ring meshes with one side of the gear.

[0006] Optionally, a protrusion is fixed to the outer wall of the limiting block. The protrusion is trapezoidal in shape, and the end of the protrusion extends out of the inner wall of the mounting ring. Multiple sets of protrusions are provided and are distributed circumferentially on the outer wall of the limiting block.

[0007] Optionally, the top end of the mounting ring is rotatably connected to a fixing plate via a rotating shaft, and a locking block is fixed to the inner wall of the fixing plate, the locking block being disposed between two sets of protrusions.

[0008] Optionally, a side block is fixed to one side of the mounting ring, a spring is fixed to the inner wall of the side block, a rod is fixed to the top of the spring, the top of the rod penetrates the inner wall of the fixing plate, and a side plate is fixed to one side of the rod.

[0009] Optionally, a gasket is fixed to the inner wall of the arc-shaped plate. The gasket is made of rubber and has an arc shape.

[0010] Optionally, a stop block is fixed to the top of the rack, and the width of the stop block is greater than the width of the rack's cross-section.

[0011] Optionally, the top of the base is fixedly connected to an inclined plate, the top of the inclined plate is fixedly connected to one side of the sensor body, and four sets of inclined plates are provided and symmetrically distributed on the top of the base.

[0014] This application, by setting up gears, racks, and arc plates, allows for the fixing of wires when necessary. By rotating the gear ring, the gear ring drives three sets of gears to rotate, and the rotation of the three sets of gears causes three sets of racks and arc plates to move simultaneously towards the center, thereby clamping both ends of the wire.

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] like Figures 1-5 As shown, this utility model proposes an anti-interference Hall sensor suitable for complex environments, comprising a base 1, a sensor body 2 fixedly connected to the top of the base 1, a connecting block 3 fixedly connected to one side of the sensor body 2, a mounting ring 4 fixedly connected to one side of the connecting block 3, and a mounting plate fixedly connected to the side of the mounting ring 4 away from the sensor body 2. Two sets of mounting plates are provided and symmetrically distributed. The outer walls of the two sets of mounting plates are fixedly connected by a connecting plate 5. A limiting sleeve 6 is fixedly connected to one side of one set of mounting rings 4. A rack 7 is slidably connected to the inner wall of the limiting sleeve 6. An arc-shaped plate 8 is fixedly connected to the bottom of the rack 7. A gear 9 is rotatably connected to one side of the sensor body 2, and the gear 9 meshes with one side of the rack 7. A limiting block 11 is rotatably connected to the inner walls of the two sets of mounting rings 4. A toothed ring 10 is fixedly connected to the inner wall of the limiting block 11, and the toothed ring 10 meshes with one side of the gear 9.

[0023] To address the issue of vibration affecting the Hall sensor's detection data, when wire testing is required, the base 1 can be fixed in place, and the wire can be passed through the interior of the sensor body 2. After the wire passes through, the transmission line used for testing can be inserted into one side of the sensor body 2. Then, the gear ring 10 inside the mounting ring 4 is rotated. The limiting block 11 provides a limit for the gear ring 10. When the gear ring 10 is rotated, it drives the gear 9 meshing on the inner wall to rotate. When the gear 9 rotates, it drives the rack 7 meshing on the other side to slide within the limiting sleeve 6. When the rack 7 moves towards the center, it drives the arc-shaped plate 8 at the bottom to move together. When the gear ring 10 rotates, it can simultaneously drive the three sets of gears 9 to rotate, thereby driving the three sets of racks 7 and arc plates 8 to move towards the center at the same time, until the inner wall of the three sets of arc plates 8 clamps the outer wall of the wire, thus fixing the position of the wire at the center of the inner wall of the sensor body 2. The other side of the sensor body 2 is also provided with three sets of arc plates 8 and racks 7, so it is convenient to fix the wires into the positions on both sides of the sensor body 2, and at the same time keep the part of the wire inside the sensor body 2 in the center. This is beneficial for the sensor body 2 to detect the current in the wire, prevent the wire from frequently changing position in a vibrating environment, and make the detected current data more accurate.

[0024] like Figure 2 The outer wall of the limiting block 11 is fixed with a protrusion 20. The protrusion 20 is trapezoidal in shape, and the end of the protrusion 20 extends out of the inner wall of the mounting ring 4. Multiple sets of protrusions 20 are provided and are distributed circumferentially on the outer wall of the limiting block 11.

[0025] By providing multiple sets of trapezoidal protrusions 20 on the outer wall of the limiting block 11, it is convenient to push the limiting block 11 and the toothed ring 10 to rotate when it is necessary to rotate the limiting block 11 and the toothed ring 10.

[0026] like Figure 5 The top end of the mounting ring 4 is rotatably connected to a fixing plate 12 via a rotating shaft. A locking block 13 is fixed to the inner wall of the fixing plate 12, and the locking block 13 is disposed between two sets of protrusions 20.

[0027] After the position of the wire is fixed, the fixing plate 12 can be flipped to one side by rotating the shaft, and the locking block 13 inside the fixing plate 12 will also be flipped until the locking block 13 is locked between the two sets of protrusions 20. This allows the locking block 13 to fix the position of the toothed ring 10 and the limiting block 11, and at the same time fix the position of the three sets of toothed racks 7 and the arc plate 8, so as to provide stable support for the wire.

[0028] like Figure 4A side block 14 is fixedly connected to one side of the mounting ring 4, a spring 15 is fixedly connected to the inner wall of the side block 14, a plug rod 16 is fixedly connected to the top of the spring 15, the top of the plug rod 16 penetrates the inner wall of the fixing plate 12, and a side plate 17 is fixedly connected to one side of the plug rod 16.

[0029] After the fixing plate 12 and the locking block 13 are flipped to the top of the protrusion 20, the spring 15 can push the insertion rod 16 upward until the insertion rod 16 penetrates the inner wall of the fixing plate 12, thereby fixing the position of the fixing plate 12. When it is necessary to release the fixation, the side plate 17 can be pulled to drive the insertion rod 16 downward and squeeze the spring 15 until the insertion rod 16 is removed from the inner wall of the fixing plate 12, thereby releasing the fixation of the position of the fixing plate 12.

[0030] like Figure 3 The inner wall of the arc plate 8 is fixed with a gasket 18, the gasket 18 is made of rubber and the gasket 18 is arc-shaped.

[0031] By setting a rubber pad 18 on the inner wall of the arc plate 8, the position of the wire can be fixed by the three sets of arc plates 8, and the outer wall of the wire can be protected by the pad 18 to prevent damage to the outer wall of the wire when the arc plate 8 clamps it.

[0032] like Figure 2 A stop 19 is fixed to the top of the rack 7, and the width of the stop 19 is greater than the width of the cross-section of the rack 7.

[0033] By setting a stop 19 at the top of the rack 7, the end of the rack 7 can be limited by the stop 19 when adjusting the position of the rack 7, so as to prevent the rack 7 from sliding out of the limiting sleeve 6.

[0034] like Figure 1 An inclined plate 21 is fixedly connected to the top of the base 1. The top of the inclined plate 21 is fixedly connected to one side of the sensor body 2. There are four sets of inclined plates 21, which are symmetrically distributed on the top of the base 1. The top of the base 1 is provided with mounting holes 22.

[0035] By setting four sets of inclined plates 21 at the top of the base 1, the stability and strength of the connection between the base 1 and the sensor body 2 can be improved after the sensor body 2 is installed. By setting mounting holes 22 at the top of the base 1, the base 1 can be installed in a designated position by screws that fit into the mounting holes 22.

[0036] like Figure 1 A heat dissipation fin 23 is fixed to one side of the sensor body 2. The heat dissipation fin 23 is provided in multiple sets and is distributed in parallel on one side of the sensor body 2.

[0037] By providing multiple sets of heat dissipation fins 23 on one side of the sensor body 2, heat can be easily released from the heat dissipation fins 23 when the sensor body 2 is running, thereby facilitating heat dissipation on one side of the sensor body 2.

[0038] In this embodiment, to address the issue of vibration affecting the Hall sensor's detection data, when wire testing is required, mounting holes 22 are provided at the top of the base 1. This allows the base 1 to be easily installed in a designated position using screws that engage with the mounting holes 22. Four sets of inclined plates 21 are provided at the top of the base 1 to improve the stability of the connection between the base 1 and the sensor body 2 after installation. The wires are then passed through the interior of the sensor body 2. After the wires have passed through, the transmission line used for testing can be inserted into one side of the sensor body 2. When it is necessary to rotate the limiting block 11 and the gear ring 10, multiple sets of trapezoidal protrusions 20 can be used to push the limiting block 11 and the gear ring 10 to rotate. By setting the limiting block 11, the gear ring 10 can be limited. When the gear ring 10 is rotated, it will drive the gear 9 meshing on the inner wall to rotate. When the gear 9 rotates, it will drive the rack 7 meshing on the other side to slide within the limiting sleeve 6. When the rack 7 moves towards the center, it will drive the arc plate 8 at the bottom to move together. When the gear ring 10 rotates, it can drive the three sets of gears 9 to rotate at the same time, thereby driving the three sets of racks 7 and the arc plate 8 to move towards the center at the same time. The inner walls of the three sets of arc-shaped plates 8 clamp the outer wall of the wire, thus fixing the wire's position at the center of the inner wall of the sensor body 2. The gasket 18 protects the outer wall of the wire, preventing damage during clamping by the arc-shaped plates 8. Three sets of arc-shaped plates 8 and a rack 7 are also provided on the other side of the sensor body 2, facilitating the fixing of the wire at both sides of the sensor body 2. This keeps the portion of the wire inside the sensor body 2 centered, enabling the sensor body 2 to detect the current within the wire and preventing frequent displacement of the wire in vibrating environments. To make the detected current data more accurate, after fixing the position of the wire, the fixing plate 12 can be flipped to one side by rotating the shaft, and at the same time, the locking block 13 inside the fixing plate 12 will also be flipped until the locking block 13 is locked between the two sets of protrusions 20. Thus, the position of the toothed ring 10 and the limiting block 11 can be fixed by the locking block 13, and the position of the three sets of toothed racks 7 and the arc plate 8 can be fixed to provide stable support for the wire. The spring 15 pushes the plug rod 16 to move upward until the plug rod 16 penetrates the inner wall of the fixing plate 12, thereby fixing the position of the fixing plate 12.

[0039] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
