Therefore, if the customer requires a limited tube size but also wants to obtain greater torque, the design will face great difficulties. To obtain greater torque, the motor size must be increased, which does not meet the customer's requirements. Therefore, further improvements are needed. Utility Model Content

[0022] like Figures 1 to 10 As shown, the present invention discloses a motor structure comprising a first motor 1, a second motor 2, a reducer 3, and a housing 4; the first motor 1, the second motor 2, and the reducer 3 are connected to an external power source; the first motor 1, the second motor 2, and the reducer 3 are all disposed within the internal cavity 7 of the housing 4; the second motor 2 and the reducer 3 are synchronously connected via a first transmission assembly 5; the second motor 2 and the first motor 1 are synchronously connected via a second transmission assembly 6; the synchronous rotation of the first motor 1 and the second motor 2 provides rotational power and rotational torque to the shaft 301 of the reducer 3.

[0023] Specifically, the first transmission assembly 5 includes a gear coupling 501 and a first transition member 502; one end of the second output shaft 201 of the second motor 2 is inserted and fixedly connected to the first transition member 502, the first transition member 502 is also inserted and fixedly connected to the gear coupling 501, and the other end of the gear coupling 501 is also inserted and fixedly connected to the rotating shaft 301 of the reducer 3; wherein, the first transition member 502 is installed inside the gear coupling 501.

[0024] In order to achieve a tighter fit with the gear coupling 501 and prevent slippage, the first transition member 502 is gear-shaped.

[0025] Specifically, to securely install the second motor 2 and the reducer 3, the first transmission assembly 5 further includes a first connecting seat 503; one end of the first connecting seat 503 is inserted and fixedly installed with the second motor 2, and the other end is also inserted and fixedly installed with the reducer 3. That is to say, both sides of the first connecting seat 503 are inserted into the housing of the second motor 2 and the housing of the reducer 3, respectively, and the first connecting seat 503 has a first receiving cavity 505 and a second receiving cavity 506 on both sides.

[0026] In order to achieve the cooperation, fixation and limiting of the reducer 3 and the first connecting seat 503, the first connecting seat 503 is provided with a first notch 504 on the outside, and the reducer 3 is provided with a first protrusion 302 that cooperates with the notch 504.

[0027] Specifically, the second transmission assembly 6 includes a motor coupling 601, a second transition member 602, and a third transition member 603; the second transition member 602 and the third transition member 603 are installed inside the motor coupling 601; one end of the motor coupling 601 is fixedly connected to the second transition member 602 (plug-in), and the other end is fixedly connected to the third transition member 603 (plug-in); the second transition member 602 is also fixedly connected to the first output shaft 101 of the first motor 1 (plug-in); the third transition member 603 is also fixedly connected to the second output shaft 201 of the second motor 2 (plug-in).

[0028] In this embodiment, in order to securely install the first motor 1 and the second motor 2, a second connecting seat 604 is also included; one end of the second connecting seat 604 is fixed to the first motor 1, and the other end is fixed to the second motor 2.

[0029] The second connecting seat 604 includes a left housing 6041 and a right housing 6042; the left housing 6041 is in contact with the right housing 6042; the left housing 6041 is fixedly engaged with the first motor 1; and the right housing 6042 is fixedly engaged with the second motor 2.

[0030] The left housing 6041 has a third receiving cavity 60411 and a fourth receiving cavity 60412 on each side. The third receiving cavity 60411 is inserted and fixed to the housing of the first motor 1, and the fourth receiving cavity 60412 accommodates the motor coupling 601. The right housing 6042 has a fifth receiving cavity 60421 and a sixth receiving cavity 60422 on each side. The fifth receiving cavity 60421 accommodates the motor coupling 601, and the sixth receiving cavity 60422 is inserted and fixed to the housing of the second motor 2.

[0031] In this embodiment, a brake assembly 8 is also included. The brake assembly 8 can control the rotation of the first motor 1 and the second motor 2 (and can control the rotation of the first motor 1 and the second motor 2 to stop at any time). The brake assembly 8 is also disposed in the internal cavity 7 of the housing 4. The brake assembly 8 includes a brake body 801 and a connector 802. The brake body 801 is connected to an external power source. One end of the connector 802 is fixedly connected to the brake body 801 by insertion, and the other end is fixedly connected to the first output shaft 101 of the first motor 1 by insertion.

[0032] To securely mount the brake body 801 and the first motor 1, the brake assembly 8 further includes a fourth connecting seat 803. One end of the fourth connecting seat 803 is fixed to the brake body 801, and the other end is fixed to the first motor 1. The fourth connecting seat 803 has a seventh receiving cavity 8031 ​​and an eighth receiving cavity 8032 on its two sides, respectively. The seventh receiving cavity 8031 ​​is inserted and fixed to the outer shell of the brake body 801, and the eighth receiving cavity 8032 is inserted and fixed to the outer shell of the first motor 1.

[0033] As can be imagined, in order to achieve rotation, the first connecting seat 503, the left housing 6041 and the right housing 6042, and the fourth connecting seat 803 all have hollow channels 10 in the middle to facilitate the rotation of the gear coupling 501, the second output shaft 201, the motor coupling 601, the first output shaft 101, and the connecting piece 802.

[0034] It also has a stroke control component 9 (the stroke control component 9 has different structures, which are existing structures and will not be described in detail here). The stroke control component 9 controls the stroke (i.e., upper and lower limits) of the first motor 1 and the second motor 2, such as controlling the forward and reverse rotation or temporary setting of the first motor 1 and the second motor 2. The stroke control component 9 is also connected to an external power supply. The stroke control component 9 is installed inside the end of the housing 4 (that is, part of the stroke control component 9 is also located inside the cavity 7).

[0035] It is worth mentioning that, in order to ensure a stable installation, the outer surfaces of the first connecting seat 503, the left housing 6041, the right housing 6042, and the fourth connecting seat 803 all have several protruding ribs 11 that help to securely install them into the housing 4.

[0036] Similarly, in order to achieve a tighter fit with the motor coupling 601 and prevent slippage, the second transition piece 602 and the third transition piece 603 are also gear-shaped.

[0037] The working principle of this structure is as follows: the rotation of the first motor 1 and the second motor 2 drives the rotation of the reducer 3's shaft 301, which in turn drives the external curtain assembly (not shown in the figure) to rotate, thereby moving the curtain up and down. Because of the use of dual motors, the rotational torque of the shaft 301 is greatly increased, allowing two small motors to obtain a large rotational torque, which means increasing the output torque and significantly enhancing the product's selling point. For example, when used with very heavy curtains, the curtains can be made even heavier, but the torque will still be sufficient to pull the curtains.

[0038] Furthermore, the brake assembly 8 can control the rotation of the first motor 1 and the second motor 2. The reducer 3 can control the speed of the first motor 1 and the second motor 2, reducing the rotational speed of the first motor 1 and the second motor 2 while increasing the output torque.

[0039] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Any appropriate changes and variations made to the above embodiments within the scope of the essential spirit of the present utility model shall fall within the scope of protection claimed by the present utility model.
