Description

Technical Field

[0001] This utility model belongs to the field of Hall sensor technology, and specifically relates to a Hall sensor structure. Background Technology

[0002] A motorcycle starter-generator mainly consists of a stator and a rotor. The stator is mounted on the engine cover, and the rotor is mounted on the engine crankshaft. The stator comprises a composite iron core, copper wire, wire clamps, wiring harness assemblies, and Hall sensor assemblies. The Hall sensor assembly is fixed to the composite iron core, and its function is to provide ignition and drive signals to the electronic control unit by sensing the changes in magnetic poles caused by the rotor's rotation. This function requires very high precision from the Hall IC element in the Hall sensor assembly.

[0003] To ensure the accuracy of Hall IC elements, additional components are often needed to restrict the position of the Hall IC elements. This structure increases the size of the Hall sensor assembly, and the increase in components also leads to increased costs and more complex manufacturing processes. Utility Model Content

[0004] The purpose of this invention is to provide a Hall sensor structure that solves the problem mentioned in the background art that the existing components used to ensure the accuracy of Hall IC elements increase the size of the Hall sensor assembly, as well as the cost and process complexity.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a Hall sensor structure, the Hall sensor comprising a sensing part and a mounting part;

[0006] The sensing unit is inserted into the mounting part, and a sensing element is mounted on the bottom of the sensing unit in a patch manner, thereby reducing the overall size of the sensing unit.

[0007] The mounting section is provided with multiple limiting parts, which are engaged with the sensing section.

[0008] Preferably, the mounting part is a housing, and the limiting part includes a signal board insertion slot, a buckle, and a signal board receiving foot;

[0009] The signal board insertion slot is located on the inner wall of the housing, and the buckle is fixed in the middle of the housing. The signal board receiving foot is located between every two signal insertion slots.

[0010] Preferably, the sensing unit includes a connection P-board and a signal P-board;

[0011] The connecting P plate has a positioning hole that engages with the buckle; the connecting P plate also has a plug-in interface.

[0012] The signal P-board is provided in multiple parts, each of which extends horizontally at the top and is T-shaped. A connector is fixed at the top of the signal P-board and is connected to the interface through it. To ensure the stability of the connection between the connecting P-board and the signal P-board, they are fixed by soldering at the connection point. The two ends of the top of the signal P-board are inserted into the signal board insertion slot. Through the setting of the signal board insertion slot and the buckle, the connecting P-board and the signal P-board can be fixedly installed respectively.

[0013] Preferably, the top of the buckle has a limiting portion and a contact surface;

[0014] The contact surface is formed in a planar shape on the outer shell, and the limiting part is placed above the contact surface. The limiting part is connected through the positioning hole, and the bottom end of the limiting part abuts against the top surface of the connecting P plate.

[0015] Preferably, the sensing element is a Hall IC element mounted on the bottom of the signal P board, and multiple Hall IC elements on the signal P boards are located on the same side.

[0016] Preferably, the signal P-board is inserted into the signal board receiving foot, and the inner contour of the outer shell has the same shape as the outer contour of the connecting P-board.

[0017] Preferably, the multiple signal P boards are arranged on the side where the connection between the P boards is not straight, and the multiple signal P boards are distributed in an arch shape.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] In this invention, a signal board insertion slot is added to the bottom of the housing. The cooperation between the signal board insertion slot and the signal P board ensures the accuracy of the Hall IC element and eliminates the need for a bracket, thereby improving production efficiency and reducing the number of parts. This not only reduces production costs but also reduces the internal space of the Hall housing, making the overall size of the Hall housing smaller. This allows for effective installation on various sizes of enclosures to meet customer needs. Furthermore, the Hall IC element is changed from a pin-type to a surface-mount type, which simplifies the process, reduces the number of processing steps, and overcomes the shortcomings of existing technologies.
