Description

Technical Field

[0001] The present application relates to the technical field of flat wire motors, and in particular to a busbar of a flat wire motor and a flat wire motor. Background Art

[0002] With the development of new energy vehicle industry, the development of its drive motor is also tending towards high voltage, high speed, integration, platformization and miniaturization. Among them, miniaturization will inevitably require a significant increase in the power density of the motor. Flat wire motors use flat copper wire in the stator winding. The winding is first made into a shape similar to a hairpin, inserted into the stator slot, and then the end of the hairpin is welded at the other end. Flat wire is conducive to improving the motor slot fill rate. Generally, the slot fill rate of round wire motors is about 40%, while the slot fill rate of flat wire motors can reach more than 60%.

[0003] For example, a Chinese patent (publication number: CN112186934B) discloses a busbar of a flat wire motor, which includes a first phase busbar, a second phase busbar, and a third phase busbar. The first phase busbar, the second phase busbar, and the third phase busbar respectively include a main body and a first connection part and a second connection part respectively located on both sides of the main body. The first connection part is connected to a first output conductor located at the outermost corresponding phase of the stator winding, and the second connection part is connected to a second output conductor located at the innermost corresponding phase of the stator winding; wherein one or two of the main bodies of the first phase busbar, the second phase busbar, and the third phase busbar are arranged between the first output conductor and the second output conductor. This application solves the problem that the internal space of the winding of the existing flat wire motor is small, which makes it difficult to arrange the busbar.

[0004] The busbar of the above-mentioned flat wire motor still has certain shortcomings. The main body of one or two phases of the three-phase busbar connected to the U-phase lead wire / V-phase lead wire / W-phase lead wire of the stator winding is located between the outermost lead wire conductor of the stator winding and the innermost lead wire conductor of the stator winding. However, since the stator winding needs to be welded to the busbar, once a problem occurs with the busbar, it is inconvenient to disassemble and replace the busbar, and the entire motor needs to be replaced, which is not only time-consuming and labor-intensive, but also costly. Therefore, the present application proposes a busbar of a flat wire motor and a flat wire motor to solve the above-mentioned problems. Utility Model Content

[0010] By adopting the above technical solution, the protective shell can be easily disassembled and assembled through the installation mechanism, and the bus body can be easily replaced.

[0011] Furthermore, two sliding rods are fixed between the left and right sides of the inner cavity of the cavity, and the push plate is slidably connected to the outer surfaces of the sliding rods.

[0017] Furthermore, a rotating handle is fixed on the opposite sides of the two threaded rods, and the lower surface of the patch is attached to the upper surface of the upper flat wire body.

Two slots 211 are provided on the upper surface of the outer shell 1, and a plurality of card slots 210 are provided on the opposite side of the two plug rods 209.

[0036] Among them, two sliding rods are fixed between the left and right sides of the inner cavity of the cavity 201, and the push plate 204 is slidably connected to the outer surface of the sliding rod to increase the stability of the push plate 204 when moving. The insertion rod 209 is slidably connected to the inside of the slot 211 to limit the protective shell 212 for easy installation. The card rod 208 is slidably connected to the inside of the card slot 210 to install and fix the protective shell 212.

[0037] In addition, the opposite sides of the two springs 207 are respectively fixed to the opposite sides of the two movable plates 205, and the opposite sides of the two springs 207 are respectively fixed to the opposite sides of the inner cavities of the two cavities 201.

The lower surface of the patch 213 is attached to the upper surface of the upper flat wire body 3, which facilitates the connection of the flat wire body 3 with the bus body 214 through the patch 213.

[0039] The installation mechanism 2 in this embodiment inserts the insertion rod 209 into the interior of the slot 211, so that the patch 213 abuts against the flat wire body 3, and rotates the rotating handle to drive the threaded rod 203 to rotate, drive the push plate 204 to move, push the moving plate 205 and the clamping rod 208 to move together and squeeze the spring 207, and the clamping rod 208 is inserted into the interior of the clamping slot 210 to fix the protective shell 212, so that the flat wire body 3 is conveniently connected to the bus body 214 through the patch 213, which is beneficial to the use of the bus body 214 and convenient for its disassembly and replacement.

[0040] Please refer again Figure 4 In order to improve the heat dissipation effect, the heat dissipation mechanism 4 in this embodiment includes a temperature detector 401 fixed on the upper surface of the inner cavity of the protective shell 212, the upper surface of the protective shell 212 is provided with two through holes 402, a connecting block 403 fixed inside the through holes 402, a semiconductor heat dissipation plate 404 fixed on the upper and lower sides of the connecting block 403, and a plurality of semiconductor heat sinks 405 fixed on the opposite sides of the two semiconductor heat dissipation plates 404.

At the same time, the lower semiconductor heat sink 405 transfers the heat to the upper semiconductor heat sink 404 and the upper semiconductor heat sink 405 through the lower semiconductor heat sink plate 404 and the connecting block 403, and finally blows away the heat under the action of air, so as to facilitate the heat dissipation of the flat wire body 3.

[0043] A flat wire motor comprises a housing 1 and a busbar of the flat wire motor arranged on the housing 1.

[0044] The working principle of the above embodiment is:

[0045] (1) When the bus body 214 needs to be installed, the insertion rod 209 is inserted into the interior of the slot 211 so that the patch 213 abuts against the flat wire body 3, and the rotating handle is turned. The rotating handle drives the threaded rod 203 to rotate in the threaded hole 202. The threaded rod 203 rotates, driving the push plate 204 to slide on the outer surface of the slide rod. During the movement of the push plate 204, it will push the moving plate 205 to move and squeeze the spring 207 and the telescopic rod 206. The moving plate 205 will also drive the clamping rod 208 to move together, so that the clamping rod 208 is clamped into the interior of the clamping slot 210, fixing the protective shell 212, and facilitating the connection between the flat wire body 3 and the bus body 214 through the patch 213, which is beneficial to the use of the bus body 214 and convenient for its disassembly and replacement.

[0046] (2) When the outer shell 1 drives the flat wire body 3 to work, heat will be generated inside the protective shell 212. The temperature of the flat wire body 3 can be monitored by the temperature detector 401. At the same time, the lower semiconductor heat sink 405 will absorb the heat and transfer the heat to the lower semiconductor heat sink 404. The lower semiconductor heat sink 404 will transfer the heat to the upper semiconductor heat sink 404 through the connecting block 403, and then transfer it to the upper semiconductor heat sink 405. Finally, the heat will be blown away by the action of air, so as to facilitate the heat dissipation of the flat wire body 3.
