Embodiment Construction

[0028] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0029] The structure of a motor flexible PG board according to the present invention is as follows: figure 1 As shown, including the substrate and the Hall circuit arranged on the substrate, the substrate of the PG board adopts a flexible circuit board 4 (FPC), and the Hall circuit arranged on the substrate is a patch type Hall circuit (SOT23).

[0030] After the Hall circuit is assembled, use commercially available conformal paint for surface treatment to achieve the effect of the existing assembled insulating sleeve. The flexible PG board of the motor saves the link of manual assembly of the insulating sleeve. The outer lead wire of the SMD Hall circuit is very short, and the solder joint 5 assembled on the FPC is very small, and the "pull" can be avoided by using ordinary three-proof paint coating. arc phenomenon". The flexible PG board of the motor real...

Abstract

The invention discloses a motor flexible PG board, which comprises a substrate and Hall circuits arranged on the substrate. The substrate of the PG board adopts a flexible circuit board. The flexible circuit board is in an E-shaped structure comprising three branches. The Hall circuits are arranged on the top ends of the three branches respectively. The three branches are mutually nonparallel; the branches at the two sides converge to the middle and form acute-angle included angles with the middle branch respectively. The motor flexible PG board is in an axisymmetric distribution structure with the branch in the middle as a symmetry axis. The step of manual assembly of an insulating bush is saved; full-automatic SMD process is realized; the flexible PG board has flexible three-dimensional space assembly capability, and the PG boards of the same type can be fit to more motors; the flexibility of the PG board helps to reduce assembly labour intensity of workers effectively; and the motor flexible PG board is compatible with the PG boards of all hub motors, including a 60-degree motor and a 120-degree motor, and hub motors of different wheel diameters.

Description

technical field [0001] The invention relates to a PG board, in particular to a PG board used in an electric vehicle. Background technique [0002] Electric vehicles have become the most convenient means of transportation for Chinese people to travel, and the demand for them is growing rapidly at home and abroad. However, there are still many manual operations in the production process of the hub motor, the key component of electric vehicles, which will threaten the quality of the vehicle, especially the production and assembly of PG boards. [0003] The PG board refers to a printed circuit board equipped with a Hall circuit for in-wheel motor commutation. Generally, the PG board is equipped with 3 Hall circuits, and damage to any one of them will cause the motor to fail. [0004] The hub motor determines the performance and quality of the vehicle, and the PG plate is the key to the performance and quality of the hub motor. The Hall circuit is an integrated circuit with lo...
