Description

Technical Field

[0001] The utility model relates to the technical field of scooters, in particular to a split-type scooter wheel hub motor. Background Art

[0002] Electric scooters are a new type of short-distance transportation tool. They are popular among consumers because they can be carried around. Existing scooters are generally equipped with batteries and wheel hub motors for easy transportation. In order to make the scooter easy to carry, the overall structure of the scooter is required to be relatively compact, and the wheel hub structure is also relatively compact.

[0003] Common wheel hub motors are split type, so the motor can be installed in the wheel hub to form a wheel hub with a motor.

[0004] However, a tire needs to be set on the outside of the wheel hub. When the tire needs to be replaced, the original tire needs to be cut off or pried out with a crowbar, and then replaced with a new tire, which means that the process is very complicated. Of course, the tire can also be removed by disassembling the split hub motor, but disassembling the hub motor is prone to damage and the disassembly process is also relatively complicated.

[0033] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0034] like Figure 1 , 5 The split-type scooter wheel hub motor shown includes a motor shaft 100 and a motor core 110 arranged on the motor shaft 100, and a first hub 200 and a second hub 300 respectively arranged on both sides of the motor core 110; wherein the first hub 200 and the second hub 300 are connected to each other to form a hub structure, wrapping the motor core 110 on the inner side, and the first hub 200 is aligned with the motor core 110 and magnetic steel sheets 101 are evenly distributed circumferentially, that is, the motor core 110 cooperates with the magnetic steel sheets 101 to form a click structure, thereby driving the first hub 200 and the second hub 300 on the outer side to rotate.

[0035] like Figure 1 , 5 As shown, the second wheel hub 300 is provided with a disassembly groove 301 near the outer side, and a wheel cover 310 is installed at the disassembly groove 301. The wheel cover 310 and the outer side of the first wheel hub 200 are provided with a tire 400, that is, the tire 400 is supported by the outer side of the first wheel hub 200 and the wheel cover 310, which is different from the traditional two and a half wheel hub support. Therefore, when replacing the tire 400, it is only necessary to remove the wheel cover 310, and it will not affect the internal structure of the hub motor.

[0036] like Figure 1 , 6 As shown, a light strip 500 is provided between the two sides of the motor core 110 and the first hub 200 and the second hub 300, and a transparent ring 600 is provided at the first hub 200 and the second hub 300 corresponding to the position of the light strip 500 for transmitting the light of the light strip 500.

[0037] Specifically, a connecting frame 111 is provided in the center of the motor core 110, and the connecting frame 111 is fixed on the motor shaft 100, thereby playing the role of fixing the motor core 110 on the motor shaft 100. Support rings 112 are provided on both sides of the connecting frame 111. The two support rings 112 pass through the connecting frame 111 and are clamped to each other. The light strip 500 is installed on the two support rings 112, that is, the support rings 112 are used to prevent the first hub 200 and the second hub 300 from touching the motor core 110 when affected by external force, and at the same time play the role of supporting the light strip 500.

[0038] like Figure 1 As shown, an inclined channel 102 is provided on one side of the motor shaft 100 close to the second hub 300 , and the wires of the motor core 110 and the light strip 500 pass through the inclined channel 102 , thereby realizing power supply for the motor core 110 and the light strip 500 .
