Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0025] Such as Figures 1-6As shown in the figure, a motor is provided, which includes a driving motor 1 and a gearbox 2. A gear transmission mechanism 3 connected to the driving motor 1 is provided inside the gearbox 2. A transmission output shaft 4 cooperatively connected to the gear transmission mechanism 3 is provided on the gearbox 2. The installation positions of the driving motor 1 and the transmission output shaft 4 are on the same side of the gearbox 2. The gearbox 2 includes a box body 201 and a box cover 202 cooperatively connected to the box body 201. The box cover 202 is fixedly installed on the box body 201 by screws and / or buckles. Specifically, the driving motor 1 and the transmission output shaft 4 are arranged on the same side of the gearbox 2, reducing the overall volume; the detachable box cover 202 can facilitate opening the installation cavity 203 for inspection, maintenance and replacement of the gear transmission mechanism, reducing the maintenance difficulty and time.

[0026] Furthermore, as Figure 3 and Figure 4 shown, a positioning seat 2011 for fixing the driving motor 1 is provided on the box body 201. A first opening 2011a through which the output shaft of the driving motor 1 passes is provided on the positioning seat 2011. The driving motor 1 is installed on the positioning seat 2011 and the output shaft of the driving motor 1 extends into the gearbox 2 through the first opening 2011a and is connected to the gear transmission mechanism 3.

[0027] Specifically, the positioning seat 2011 ensures the position accuracy of the driving motor 1 during installation, enabling the output shaft of the driving motor 1 to be accurately docked with the gear transmission mechanism 3, reducing the installation error and improving the transmission efficiency. The rotational power generated by the driving motor 1 is transmitted to the gear transmission mechanism 3 through the output shaft, and then transmitted by the gear transmission mechanism 3 to the transmission output shaft 4.

[0028] Furthermore, as Figure 3 and Figure 4 shown, an installation cavity 203 for installing the gear transmission mechanism 3 is formed between the box body 201 and the box cover 202.

[0029] Specifically, the installation cavity 203 effectively encloses the gear transmission mechanism 3 between the box body 201 and the box cover 202, providing good protection against the entry of external dust and impurities, and extending the service life of the gear transmission mechanism 3.

[0030] Furthermore, as Figure 3 、 Figure 5 and Figure 6 shown, the motor further includes a dust-proof cover 5 for covering the driving motor 1.

[0033] Specifically, the sequential transmission connection between the multi-stage transmission gears makes the transmission process smoother, reduces vibration and noise, and improves the smoothness and comfort of the transmission system. The drive motor 1 is fixed on the box body 201 through the positioning seat 2011, and the output shaft passes through the first opening 2011a and extends into the installation cavity 203 to be connected to the first-stage transmission gear 301. The first-stage transmission gear 301 drives the second-stage transmission gear 302, the second-stage transmission gear 302 then drives the third-stage transmission gear 303, and so on. Finally, the fifth-stage transmission gear 305 outputs power, and the fifth-stage transmission gear 305 transmits the rotational power to the transmission output shaft 4, and the transmission output shaft 4 outputs the power to the external load.

[0034] Furthermore, as Figure 3 , Figure 5 and Figure 6 shown, fixing parts 204 for fixing the gear shaft 306 are respectively provided on the inner side walls of the box body 201 and the box cover 202, and the front and rear ends of the gear shaft 306 are positioned and installed on the fixing parts 204.

[0035] Specifically, the fixing parts 204 ensure the position accuracy of the gear shaft 306, enabling the multi-stage transmission gears to mesh precisely, and improving the transmission efficiency and transmission accuracy.

[0036] Furthermore, as Figure 5 and Figure 6 shown, a second opening 205 for the transmission output shaft 4 is provided on the gearbox 2, and the transmission output shaft 4 is cooperatively connected with the fifth-stage transmission gear 305 and passes through the second opening 205 and extends towards one side of the gearbox 2.

[0037] Specifically, the transmission output shaft 4 is connected to the five-stage transmission gear 305 in a mating manner, passes through the second opening 205 on the gearbox 2, and extends towards the side of the gearbox 2 to transmit power to an external load; the second opening 205 ensures that the transmission output shaft 4 can smoothly pass through the gearbox 2 and maintains its stability and position accuracy.

[0038] Furthermore, as Figure 5 and Figure 6 shown, a pin 6 is provided at one end of the transmission output shaft 4, and a positioning groove 3051 that mates with the pin 6 is provided on the five-stage transmission gear 305. The transmission output shaft 4 is connected to the five-stage transmission gear 305 in a mating manner through the pin 6.

[0039] Specifically, through the cooperation of the pin 6 and the positioning groove 3051, the connection between the transmission output shaft 4 and the five-stage transmission gear 305 is more stable, reducing the looseness and slippage that may occur during operation, and improving the stability and reliability of the motor.

[0040] Furthermore, as Figure 5 and Figure 6 shown, a bearing 7 is also provided at one end of the transmission output shaft 4, a bushing 8 is provided at the other end of the transmission output shaft 4, a first positioning portion 2013 for fixing the bushing 8 is provided on the housing 201, and a second positioning portion 2021 for fixing the bearing 7 is provided on the cover 202. The transmission output shaft 4 passes through the bushing 8 and extends out from the second opening 205; the central axes of the bearing 7, the bushing 8, and the transmission output shaft 4 are collinear.

[0041] Specifically, the bearing 7 and the bushing 8 provide additional support for the transmission output shaft 4, reducing vibration and swing during operation, and improving the stability and reliability of the system; the bearing 7 and the bushing 8 can reduce friction and wear of the transmission output shaft 4 during operation, extend the service life of the transmission system, and improve the transmission efficiency; the first positioning portion 2013 and the second positioning portion 2021 ensure that the central axes of the bearing 7, the bushing 8, and the transmission output shaft 4 are collinear, improving the transmission accuracy and installation accuracy.

[0042] Furthermore, as Figures 1-4 shown, the transmission output shaft 4 is located below the drive motor 1.

[0043] Specifically, the vertical arrangement design makes the installation and maintenance of the transmission output shaft 4 and the drive motor 1 more convenient, reduces the limitation of the operating space, effectively utilizes the space, makes the entire motor more compact, and is suitable for application scenarios with limited space.
