Description

Technical Field

[0001] The utility model relates to the technical field of motors, in particular to an internal electrical connection structure of an integrated motor. Background Art

[0002] A motor with an integrated controller is an advanced electric drive unit that tightly integrates the motor and controller into a compact, high-performance unit. This design promotes the motor's integrity and miniaturization. However, this highly integrated solution also presents the challenge of wiring complexity. Because power and signals need to be transmitted between the controller and the motor, the wiring layout becomes complex, and wiring reliability must also be carefully considered. Therefore, despite the excellent performance of new energy motors with integrated controllers, their wiring difficulty remains a significant drawback.

[0003] In the prior art, patent CN 220754521 U discloses a post-controller motor wiring structure, in which the controller box cover is directly fixed to the tail of the machine base. During installation, it is necessary to first connect the coil winding wiring in the machine base to the winding coil terminal. Output terminals are arranged in the controller box cover, and the winding coil terminal is plug-in electrically connected to the output terminal. In this structure, on the one hand, the operation of connecting the winding wiring to the terminal needs to be completed manually in sequence, which is difficult to automate, affecting the installation efficiency. On the other hand, the plug-in electrical connection structure has poor reliability and may cause poor contact. In addition, the heat generated by the controller part and the motor part will affect each other, affecting the stability of the motor. Utility Model Content

[0004] Purpose of the invention: In order to overcome the deficiencies in the prior art, the utility model provides an internal electrical connection structure of an integrated motor with convenient connection and high reliability.

[0006] The partition plate has a through slot; the stator has three hard connecting units passing through the through slot; three connecting plates are connected to the control board; a connecting block is fixed to the partition plate, and the connecting block has three connecting slots, and each connecting slot has a connecting unit and a connecting plate connected to each other.

[0007] Furthermore, the connected connecting units and connecting pieces are both secured to the connecting block by a single screw. The second housing has a window facing the connecting block, with a removable cover installed on the window. During use, the control board is secured within the second housing. After the motor and controller are mounted on either side of the partition, each connecting unit and connecting piece is inserted into its corresponding connecting slot. Screws are then driven through the window into the connecting block to secure the connecting units and connecting pieces relative to the connecting block.

[0008] Furthermore, the connecting piece is L-shaped, with one end connected to the control board and the other end inserted into the connecting groove. With this structure, it is convenient to connect the connecting ends at different positions of the control board to the connecting groove and establish a connection with the corresponding connecting unit.

Simply screwing in the screws can complete the connection and fix it, avoiding complex wiring. The connection reliability is very high and there is no possibility of poor contact. In addition, the partition plate can fully separate the motor and controller parts, preventing them from affecting each other and maintaining the stability of the motor operation.

[0023] like Figure 3 As shown, the partition plate 1 has a through slot 1a; the stator 3 has three hard connecting units 3a passing through the through slot 1a; the control board 6 is connected to three connecting pieces 6a; the partition plate 1 is fixed with a connecting block 7, as shown Figure 5 As shown, the connection block 7 has three connection grooves 7 a , and each of the connection grooves 7 a has one of the connection units 3 a and one of the connection pieces 6 a connected to each other.

[0024] The connected connecting unit 3a and connecting piece 6a are both secured to the connecting block 7 by a single screw 8. The second housing 5 has a window 5a facing the connecting block 7, with a removable cover 5B mounted on the window 5a. During use, the control board 6 is secured within the second housing 5. After the motor portion A and controller portion B are mounted on either side of the partition plate 1, each connecting unit 3a and connecting piece 6a is placed into its corresponding connecting slot 7a. Screws 8 are then driven through the window 5a into the connecting block 7 to secure the connecting unit 3a and connecting piece 6a relative to the connecting block 7.

[0025] By adopting the electrical connection method of the present invention, the overall layout of the integrated motor can be made compact and easy to install. When the motor part A and the controller part B are respectively installed on both sides of the partition plate 1, the ends of the connecting unit 3a and the connecting piece 6a are simultaneously in place. The connection and fixation can be completed by simply screwing in the screw 8, avoiding complicated wiring. The connection reliability is very high and there will be no poor contact.
