Abstract
Description
Technical Field
[0001] This utility model relates to the field of electric vehicle controller technology, and in particular to a motor Hall switching circuit and device. Background Technology
[0002] In the electric bicycle industry, the Hall signals used by motors and controllers of different brands and models vary, mainly in the phase sequence of the Hall signals and the differences in Hall signal characteristics between 60-degree and 120-degree motors. Currently, the common standards for Hall signals of electric bicycle motors on the market are general standards and manufacturer-specific standards.
[0003] Existing technologies typically employ complex methods to address compatibility issues between Hall effect signals from motors of different standards. When adjusting the Hall effect sequence, technicians often need to manually connect different lines to try various phase sequence combinations to determine the appropriate Hall effect phase sequence. This method is not only cumbersome and inefficient but also demands a high level of expertise and experience from the technicians. For example, determining the phase sequence for a 60-degree motor and a 120-degree motor requires a deep understanding of the motor's internal structure and the principles of Hall effect signals to connect the wiring correctly. This results in a heavy workload and high labor intensity for technicians, and is prone to connection errors that can affect the normal operation of the motor. Furthermore, existing technologies lack a convenient and universal adapter cable, making it impossible to quickly and accurately convert between different motor Hall effect signal standards. When the motor or controller of an electric bicycle needs to be replaced with a product of a different standard, it often requires rewiring or replacing the entire control circuit, increasing maintenance and replacement costs and causing inconvenience to users.
[0004] Therefore, there is a need for a technical solution that does not rely on manual wiring and allows for arbitrary switching of Hall effect sensors for different motors. Utility Model Content

[0040] The first output interface J1 is used to output a motor Hall signal of the first target type. Its power supply terminal, ground terminal GND, and motor temperature control terminal TEMP are electrically connected to the power supply terminal, ground terminal GND, and motor temperature control terminal TEMP of the second output interface J2, the first input interface J3, and the second input interface J4, respectively. Its first Hall signal terminal is electrically connected to the first Hall signal terminal of the second output interface J2 as a first common Hall terminal HU and connected to the first output terminal of the button matrix module 11. Its second Hall signal terminal is electrically connected to the second Hall signal terminal of the second output interface J2 as a second common Hall terminal HV and connected to the second output terminal of the button matrix module 11. Its third Hall signal terminal is electrically connected to the third Hall signal terminal of the second output interface J2 as a third common Hall terminal HW and connected to the third output terminal of the button matrix module 11.
[0041] The second output interface J2 is used to output a motor Hall signal of the second target type;
[0042] The first input interface J3 is used to input a first type of motor Hall signal. Its first Hall input phase line is electrically connected to the first Hall input phase line of the second input interface J4 as a first common Hall input phase line A and connected to the first input terminal of the button matrix module 11. Its second Hall input phase line is electrically connected to the second Hall input phase line of the second input interface J4 as a second common Hall input phase line B and connected to the input terminal of the reverse module 12. Its third Hall input phase line is electrically connected to the third Hall input phase line of the second input interface J4 as a third common Hall input phase line C and connected to the third input terminal of the button matrix module 11.
[0043] The second input interface J4 is used to input a second type of motor Hall signal;
[0044] The button matrix module 11 is used to connect the first common Hall terminal HU, the second common Hall terminal HV, and the third common Hall terminal HW to its first input terminal, second input terminal, and third input terminal in a target order through button operation, and its second input terminal is electrically connected to the output terminal of the inverting module 12.
[0045] In this embodiment, the first output interface J1, the second output interface J2, the first input interface J3, and the second input interface J4 can use conventional Hall effect terminals. The motor Hall signal of the first target type can be a general standard motor Hall signal, and the motor Hall signal of the second target type can be a motor Hall signal of a specific manufacturer's standard. The motor Hall signal of the first type can be a general standard motor Hall signal, and the motor Hall signal of the second type can be a motor Hall signal of a specific manufacturer's standard. The first output interface J1 adopts a general standard output, the second output interface J2 adopts a specific manufacturer's standard, the first input interface J3 adopts a general standard input, and the second input interface J4 adopts a specific manufacturer's standard input. The first output interface J1 and the second output interface J2 are used to connect the motor, and the first input interface J3 and the second input interface J4 are used to connect the controller. The output signals of the first output interface J1 and the second output interface J2 include six signals: 5V power supply (corresponding to the power supply terminal), GND ground (corresponding to the ground terminal GND), motor temperature control (corresponding to the motor temperature control terminal TEMP), Hall U (corresponding to the first common Hall terminal HU), Hall V (corresponding to the second common Hall terminal HV), and Hall W (corresponding to the third common Hall terminal HW). The button matrix module 11 can be a 3×3 button matrix. Internally, the button matrix module 11 incorporates electronic switch circuitry. By pressing different button combinations, the connection of the signal lines can be changed, thereby altering the order of the input Hall signals UVW, enabling Hall signal output in six sequences: UVW, UWV, VUW, VWU, WUV, and WVU. The inverting module 12 can be constructed based on conventional transistors and electronic switches. When converting a 60-degree motor to a 120-degree motor (or vice versa), the electronic switch in the inverting module 12 reverses the B-channel Hall signal, achieving signal inversion and ensuring controller compatibility with both 60-degree and 120-degree motors. This application employs manual button operation, eliminating the need for complex automatic detection and feedback systems, resulting in lower costs and easier understanding and control for experienced manual operators. The motor Hall switching circuit in this application not only enables motor Hall signal switching but also serves as a debugging tool and adapter, meeting the needs of various scenarios.

Figure 2 When the angle switching button S1 is not pressed, the B-IN terminal is connected to the B terminal, and there is no reverse operation. After the angle switching button S1 is pressed, when the B terminal outputs a high level, the signal is transmitted to the BT terminal, the base voltage of transistor Q1 increases, transistor Q1 conducts, its collector voltage decreases, the BF terminal is at a low level, and the low-level signal is transmitted to the B-IN terminal; when the B terminal outputs a low level, the signal is transmitted to the BT terminal, transistor Q1 is cut off, the BF terminal is at a high level, and the high-level signal is transmitted to the B-IN terminal.
