Abstract
Description
Technical Field
[0001] The utility model relates to a high-efficiency modular motor assembly mechanism. Background Art
[0002] As the key to controlling carbon emissions, the automotive industry is bound to adopt new energy vehicles. However, unlike traditional vehicles, new energy vehicles are increasingly using brushless DC motors to meet usage needs.
[0003] The existing inner rotor brushless motor assembly technology can meet the production requirements of brushless motors to a certain extent, but it still has obvious processing difficulties.
[0004] Most inner rotor brushless motors are welded with electronic control components and stator enameled wires before installing the rear cover. The process is complex, the processing is difficult, and the consistency of processing cannot be guaranteed. The investment in the motor production line is huge. Therefore, how to quickly assemble the motor has always been a difficult and hot issue in the industry.
[0005] The wiring harness is passed through a two-color injection-molded rubber block and then welded to the PCBA. After completion, the dust cover is fastened and then filled with sealant. The process has many steps and high technological requirements, which can easily lead to poor sealing and reduced waterproof level of the motor. Utility Model Content
[0006] The technical problem to be solved by the utility model is: to provide a high-efficiency modular motor assembly mechanism in view of the problems of complex motor assembly process and poor sealing in the prior art.
[0007] In order to achieve the above object, the utility model is realized by the following technical solutions:
[0008] A high-efficiency modular motor assembly mechanism comprises a stator winding, a terminal, a PCBA board and a rear cover; the rear cover is plugged into the PCBA board, and an electrical connection port is provided on the PCBA board;
[0009] The terminal comprises a terminal body and connectors at both ends of the terminal body, the connector at one end of the terminal is connected to the stator winding, and the connector at the other end of the terminal is connected to the electrical connection port on the PCBA board.
[0010] The connecting piece of the terminal is a hook or a plug interface.
[0011] The back cover is provided with a slot, and the PCBA board is inserted into the slot.
[0012] A connection interface is also provided on the rear cover, and the connection interface is connected to the integrated plastic-coated wiring harness.
[0013] Compared with the prior art, the utility model has the following beneficial effects: the utility model adopts modular assembly, which can avoid welding the stator enameled wire and the electronic control component, and there is no motor failure caused by poor welding. And the wiring harness of the electronic control component will not cause the waterproof level to decrease due to the process out of control. The assembly method of the integrated plastic-coated wiring harness and the stator component terminal inserted into the electronic control component greatly improves the production efficiency and ensures product consistency. BRIEF DESCRIPTION OF THE DRAWINGS
[0014] Figure 1 It is the overall structure diagram of the utility model;
[0015] Figure 2 This is a structural diagram of the integrated plastic-coated wiring harness. DETAILED DESCRIPTION
[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0017] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.
[0018] like Figure 1 As shown, a high-efficiency modular motor assembly mechanism includes a stator winding 1, a terminal 2, a PCBA board 3 and a back cover 4.
[0019] The stator winding 1 is produced separately, and the stator winding 1 is directly hung on the butted terminal 2, so as to ensure the automated processing of the stator as a whole.
[0020] The back cover 4 is provided with a slot 5 into which the PCBA board 3 is inserted, and the back cover 4 is also provided with a connection interface 6 connected to an integrated plastic-coated wiring harness 7 .
[0021] The PCBA board 3 is provided with an electrical connection port, and the terminal 2 is connected to the electrical connection port;
[0022] The terminal 2 includes a terminal body and connectors at both ends of the terminal body, the connectors being hooks or plug interfaces. The connector at one end of the terminal 2 is connected to the stator winding 1, and the connector at the other end of the terminal 2 is connected to the electrical connection port of the PCBA board 3.
[0023] The assembly principle of the utility model is:
[0024] First, the PCBA board 3 is assembled with the back cover 4, and then assembled with the stator winding 1 through the terminal 2. The terminal 2 is directly inserted into the PCBA board 3, and does not need to be led to the PCBA board through welding. In this way, the motor adopts modular assembly, and the stator winding 1 is directly hung on the docking terminal 2, ensuring the automatic processing of the stator as a whole.
[0025] In addition, the utility model adopts an integrated plastic-coated wire harness, and the wire harness is directly installed and processed as a whole, avoiding difficult operations such as threading, and is fastened together with the rear cover 4 by screws after plastic coating.
[0026] This assembly method does not require welding of the stator enameled wire and the electronic control component, and there is no motor failure caused by poor welding. In addition, the wiring harness of the electronic control component will not reduce the waterproof level due to process loss. The assembly method of the integrated plastic-coated wiring harness and the stator component terminals inserted into the electronic control component greatly improves production efficiency and ensures product consistency.
[0027] The above is only a preferred embodiment of the present invention. It should be pointed out that those skilled in the art can make several changes and improvements without departing from the overall concept of the present invention, and these should also be regarded as the protection scope of the present invention.
