[0031] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0032] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings. Example 1

[0033] Please refer to Figure 1-3 A motor mechanism for a plug door includes a motor 100, a gear box 200, a coupling 300, an upper cover 400, a lower cover 500 and a bracket 600. The motor 100 and the gear box 200 are both installed on the bracket 600.

The upper cover 400 and the lower cover 500 are arranged opposite to each other and form an internal hollow structure after buckling. The coupling 300 is arranged in the internal hollow structure.

[0034] Through the above structural design, the output end of the separate motor 100 is connected to the input end of the separate gear box 200 through the coupling 300. Since the motor 100 is fixed, the wiring harness of the motor 100 is fixed, and the gear box 200 rotates at a certain angle, it is beneficial to enhance the safety of the wiring harness of the motor 100. At the same time, due to the split design, if one of the motor 100 and the gear box 200 fails, there is no need to scrap them together. An upper cover 400 and a lower cover 500 are provided at the connection place of the coupling 300 for protection, which is beneficial to keep the overall rigidity unchanged and to the utilization of resources.

[0035] Please refer to Figure 4Specifically, the gearbox 200 includes a housing 210, an input shaft 220, an output shaft 230, an active bevel gear 240, a transmission bevel gear 250 and a driven bevel gear 260. The input shaft 220 and the output shaft 230 are horizontally arranged in the front and rear of the housing 210, respectively. The active bevel gear 240 is fixed on the input shaft 220, and the driven bevel gear 260 is fixed on the output shaft 230. The transmission bevel gear 250 is transmission-connected with the active bevel gear 240 and the driven bevel gear 260. The housing 210 is filled with lubricating oil 270.

[0036] Specifically, the driving bevel gear 240 and the driven bevel gear 260 are both meshed and driven with the transmission bevel gear 250 .

[0037] Specifically, the lubricating oil 270 is collected in the housing 210 to form a lubricating oil pool, and a portion of the driving bevel gear 240 and a portion of the driven bevel gear 260 are immersed in the lubricating oil pool.

[0038] Through the above structural design, the gearbox 200 has the following functions: 1. Acceleration and deceleration, which is often called the speed change gearbox 200. 2. Change the transmission direction, and use two fan gears to vertically transmit the force to another rotating shaft. 3. Change the torque. Through the cooperation of the active bevel gear 240, the transmission bevel gear 250 and the driven bevel gear 260, the force of the motor 100 is transmitted to the input shaft 220 and the output shaft 230 through the coupling 300, and the lubricating oil 270 is helpful to reduce the friction during the transmission process.

[0043] Through the above structural design, the sensor 290 is set inside the gear box 200, and the buoy 291 floats on the lubricating oil 270 and will rise with the increase of the lubricating oil 270. When the sensor 290 detects that the buoy 291 is within the detection range, it will send an instruction to the controller, and the controller will buzz and stop adding lubricating oil 270.

[0044] Specifically, the sensor 290 is an oil level sensor 290 or a liquid level switch sensor 290 .

[0045] Through the above structural design, in this embodiment, the sensor 290 is an oil level sensor 290 .
