Description

Technical Field

[0001] This utility model relates to the technical field of magnetic induction sensor switch modules, specifically to a single-stance magnetic induction sensor switch module for a two-wheeled electric vehicle. Background Technology

[0002] Chinese patent announcement number CN205769806U, published on December 7, 2016, discloses an electronic induction power-off switch for a single stand on a two-wheeled electric vehicle. The switch includes a positioning turntable with a magnetic sensor, a signal transceiver module, an indicator light, and an external power supply and signal output line. A turntable, which can rotate freely relative to the turntable, has a magnet installed inside. When the magnet on the turntable rotates to the position corresponding to the magnetic sensor, the signal transceiver module outputs an on signal; when the magnet on the turntable moves away from the magnetic sensor's position, the signal transceiver module outputs a off signal. The positioning turntable and the turntable are assembled as a single unit and mounted on the single stand. After installation, the positioning turntable is positioned, and the turntable and the single stand rotate together. The shortcomings of this existing technology are: the overall support consists of a positioning turntable, a turntable, and a mounting base, resulting in a relatively complex structure; and the magnetic field utilization rate is relatively low. Therefore, improvements are urgently needed. Utility Model Content

[0003] To address the above problems, this utility model provides a single-stance magnetic induction sensor switch module for two-wheeled electric vehicles, which simplifies the structure, facilitates assembly and maintenance, has high magnetic field utilization, and reduces signal interference.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a single-stance magnetic induction sensor switch module for a two-wheeled electric vehicle, comprising a housing, a rotor, a hollow shaft, a PCB board, a magnetic induction sensor, and multiple magnets. The rotor is rotatably fitted inside the housing. The housing has a positioning hole, and a hollow guide seat coaxially penetrating the positioning hole is formed on one side of the rotor. A hollow shaft is coaxially fixedly installed inside the hollow guide seat. A limiting boss that contacts a boss on the housing is formed on the free end of the hollow guide seat penetrating one side of the housing. Multiple magnet storage slots are formed on the side of the rotor corresponding to the hollow guide seat, and a magnet is fitted into each magnet storage slot. The depth of the magnet storage slot is set to A, and the thickness of the magnet is set to B, where A > B. The PCB board is plastic-encapsulated and fixed on the side of the housing corresponding to the magnet storage slot. The magnetic induction sensor is integrated on the PCB board and its position corresponds to the magnet. An external power supply and signal output line are connected to the PCB board, and the external power supply and signal output line extend out of the housing.

[0005] Preferably, there are 3 magnet storage slots and 3 magnets.

[0006] Preferably, the outer casing houses the inner cavity of the rotor and is provided with a limiting groove coaxially near the positioning hole, and the side of the rotor with the magnet receiving groove is formed with a guide boss embedded in the limiting groove.

[0007] The beneficial effects of this utility model are:

[0008] 1. The overall support consists of a simplified structure of the outer shell and the rotor. The outer shell is limited by the limiting boss, which facilitates assembly and maintenance while ensuring structural compactness.

[0009] 2. The rotor is equipped with multiple magnets, and the magnetic induction sensor is integrated on the PCB board and its position corresponds to the magnet. On the one hand, it enhances the utilization rate of the magnetic field. On the other hand, the integration of the magnetic induction sensor on the PCB board facilitates optimized wiring, thereby reducing signal interference. Furthermore, it is compatible with multiple signal outputs, such as analog signals, PWM signals, and digital signals.

[0010] 3. By setting a hollow rotating shaft, which is fixed coaxially with the hollow guide seat, the hollow design reduces the moment of inertia;

[0011] 4. The PCB board is plastic-encapsulated and fixed inside the housing, which completely seals the electrical components, thus providing excellent waterproof and dustproof functions and extending its service life. Attached Figure Description

Detailed Implementation

The rotor 11 is rotatably fitted inside the housing 10. The housing 10 has a positioning hole 19. A hollow guide seat 17, coaxially penetrating the positioning hole 19, is formed on one side of the rotor 11. The hollow shaft 12 is coaxially fixedly installed inside the hollow guide seat 17. A limiting boss, which abuts against a boss 22 on the housing 10, is formed on the free end of the hollow guide seat 17 penetrating one side of the housing 10. 23; A plurality of magnet storage slots 16 are formed on one side of the rotor 11 corresponding to the hollow guide seat 17. A magnet 15 is embedded in each magnet storage slot 16. The depth of the magnet storage slot 16 is set as A, and the thickness of the magnet 15 is set as B, where A > B; A PCB board 14 is plastic-encapsulated and fixed on one side of the outer shell 10 corresponding to the magnet storage slot 16. The magnetic induction sensor 21 is integrated on the PCB board 14 and its position corresponds to that of the magnet 15; An external power supply and signal output line 13 are connected to the PCB board 14 and extend out of the outer shell 10.

[0020] In this embodiment, there are 3 magnet storage slots 16 and 3 magnets 15.

[0021] The outer casing 10 houses the inner cavity of the rotor 11 and is provided with a limiting groove 20 coaxially near the positioning hole 19. The side of the rotor 11 with the magnet storage groove 16 has a guide boss 18 embedded in the limiting groove 20.

[0022] In actual use, the positioning groove 23 is embedded in the positioning pin on the single support to achieve positioning. When the single support rotates, the outer shell 10 is fixed, and only the rotor 11 rotates with the single support. The rotor 11 rotates to the corresponding position of the magnetic induction sensor 21 through the magnet 15 to achieve signal output connection.

[0023] In this embodiment, the overall support consists of a simplified structure composed of a shell and a rotor. Limiting bosses constrain the shell, ensuring structural compactness while facilitating assembly and maintenance. The rotor is equipped with multiple magnets, and a magnetic induction sensor is integrated onto the PCB board, its position corresponding to the magnets. This enhances magnetic field utilization and, moreover, optimizes wiring by integrating the magnetic induction sensor onto the PCB board, reducing signal interference. Furthermore, it is compatible with various signal outputs, such as analog signals, PWM signals, and digital signals. A hollow rotating shaft, coaxially fixed with a hollow guide seat, reduces rotational inertia. The PCB board is encapsulated within the shell, ensuring complete electrical sealing and providing excellent waterproof and dustproof capabilities, thus extending its service life.
