Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of brushless motors, in particular to a connecting plate for a brushless motor. Background Art
[0002] A brushless motor is a motor that uses an electronic commutator to control the polyphase current on the stator, thereby generating a rotating magnetic field to drive the permanent magnet in the rotor to rotate. During its operation, there is no physical contact, achieving efficient and low-noise power output.
[0003] For the existing connecting plate of a brushless motor, such as a connection structure of a control circuit board of a brushless motor disclosed in the utility model patent with the application number 202220894713.7, its main structure includes an insulating sheet and a circuit board arranged on the motor. The insulating sheet has a through hole in the center, and a plurality of winding groups are evenly distributed on its inner wall. The outer side walls of each winding group combine to form the hole wall of the through hole. The insulating sheet includes an upper end face and a lower end face. At least two hooks are provided on the upper end face, the hooks are specifically elastic, at least three support members are provided on the upper end face, at least two insertion parts are provided on the lower end face, and the circuit board has a center hole in the center; during use, by providing hooks on the insulating sheet and then providing notches on the circuit board, the detachable assembly of the insulating sheet and the circuit board is realized by the adaptation of the hooks and the notches.
[0004] However, the existing connecting plate of a brushless motor is generally connected by welding. Resistance welding has the risks of virtual welding and unreliable welding, and it is difficult to assemble, with many single parts. Summary of the Utility Model
[0005] To solve the above technical problems, the utility model provides a connecting plate for a brushless motor that can not only integrate U / V / W into one body and separate them individually without contact to ensure the realization of functions, but also the welding of one hook and one wire is more reliable and has lower risks than the welding of one hook and two wires or one hook and multiple wires, and the tooling and welding equipment can more easily achieve the unification of parameters.
[0006] A connecting plate for a brushless motor of the utility model includes a brushless motor; it further includes three groups of connecting mechanisms and an integrating mechanism. The three groups of connecting mechanisms are installed on the brushless motor to avoid the risk of poor welding. The integrating mechanism is installed on the connecting mechanisms and integrates the U / V / W three-phase terminals and the connecting wires into one body; the three groups of connecting mechanisms are arranged vertically, increasing the cross-sectional area, which can adapt to a larger operating power, prevent wire detachment and facilitate resistance welding, improving the welding quality. Then the integrating mechanism integrates the U / V / W three-phase terminals and the connecting wires into one body, and connects the enameled wire and the integrating mechanism through resistance welding. The structure is simple and the installation is convenient.
[0007] Preferably, the brushless motor includes a motor stator, connecting wires, and multiple groups of positioning bolts. The motor stator is installed inside the motor protection housing, the connecting wires are wound around the motor stator, and multiple groups of positioning bolts are all installed on the motor stator. Winding the connecting wires around multiple winding posts on the motor stator facilitates generating electromagnetic force to drive the main shaft to rotate, and setting multiple groups of positioning bolts facilitates fixing the integrated mechanism.
[0008] Preferably, the connecting mechanism includes phase wire terminals, hooks, and insertion plates. The phase wire terminals are installed on the motor stator, the hooks are hooked on the connecting wires, and the insertion plates are installed on the phase wire terminals. Three groups of connecting mechanisms are arranged vertically on the motor stator. Hanging the hooks on the connecting wires facilitates power conduction, and then the phase wire terminals transmit the power to the integrated mechanism through the insertion plates for integration. By arranging the three groups of connecting mechanisms vertically, the cross-sectional area is increased, enabling it to be applicable to high-power operation.
[0009] Preferably, the hook also has an opening of 20°, and an arc-shaped convex platform is designed inside the hook. By setting the arc-shaped convex platform on the hook, wire detachment can be prevented and resistance welding is facilitated, improving the welding quality.
[0010] Preferably, the integrated mechanism includes a connecting plate, three groups of connecting seats, and multiple groups of positioning seats. The connecting plate is installed on the motor stator, three groups of connecting seats are all installed on the connecting plate, slots are opened on the connecting seats, multiple groups of positioning seats are all installed on the connecting plate, and positioning holes are opened on the positioning seats. By setting the arc-shaped convex platform on the hook, wire detachment can be prevented and resistance welding is facilitated, improving the welding quality.
[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows: The three groups of connecting mechanisms are arranged vertically, increasing the cross-sectional area, enabling it to adapt to a larger operating power, preventing wire detachment and facilitating resistance welding, improving the welding quality. Then, the integrated mechanism integrates the U / V / W three-phase terminals and the connecting wires into one body, and connects the enameled wire and the integrated mechanism through resistance welding. The structure is simple and the installation is convenient. Description of the Drawings
