As shown in fig. 2, in an embodiment of the present application, the first motor 100 includes: a motor induction module 110, a motor main body 120, a motor fixing member 130, a driving gear bearing 140, and a driving gear shaft 150;

the motor induction module 110 is connected with the motor main body 120, and the motor induction module 110 acquires an external induction signal and controls the motor main body 120 to work after receiving the external induction signal; specifically, for example, when the motor sensing module 110 senses that there is a human body within a set distance, the motor sensing module 110 is started to operate, and the motor main body 120 is controlled to operate, or the motor sensing module 110 receives a control instruction sent by an external main control module and used for controlling the motor main body 120 to start, and the motor sensing module 110 controls the motor main body 120 to operate.

The motor main body 120 is fixed on the motor fixing member 130, and the motor fixing member 130 is used for fixing the motor main body 120 on the housing 500; as shown in fig. 2, the first end of the motor fixing member 130 is a circular ring-shaped cavity, the circular ring-shaped cavity is fixed outside the housing 500, the second end of the motor fixing member 130 is a square structure, and the motor main body 120 is fixed at the second end of the motor fixing member 130 by a bolt, so that the motor main body 120 is fixed on the housing 500 by the motor fixing member 130, and since the first end of the motor fixing member 130 is a cylindrical cavity structure, the output shaft of the motor main body 120 can penetrate into the interior of the cylindrical cavity at the first end of the motor fixing member 130.

The driving gear bearing 140 is disposed inside the motor fixing part 130, and the driving gear bearing 140 is fixed inside the motor fixing part 130, so that the position of the driving gear bearing 140 is kept unchanged; at this time, if the motor main body 120 rotates, the driving gear shaft 150 is driven to rotate, and since the outer ring of the driving gear bearing 140 is fixed inside the motor fixing member 130, the driving gear shaft 150 rotates at the inner ring of the driving gear bearing 140.

Due to the gear of the drive gear shaft 150 and the teeth of the first shaft structure 300

The gears are engaged, so that the gear rotation speed of the driving gear shaft 150 is consistent with the gear rotation speed of the first shaft structure 300, and the diameter ratio of the gear of the driving gear shaft 150 to the gear of the first shaft structure 300 is set, so that the angular speed increasing rotation, the angular speed decreasing rotation or the angular speed equiangular rotation of the first shaft structure 300 can be realized, and the accurate control of the rotation speed of the first shaft structure 300 is realized.

In one embodiment of the present application, as shown in fig. 3, the first shaft structure 300 includes: a first dead point bearing 310, a first shaft 320, a first inter-shaft fixed bearing 330, a first driven gear 340 and a first limit 350;

The outer ring of the first inter-shaft fixed bearing 330 is fixed on the first shaft 320, and the inner ring of the first inter-shaft fixed bearing 330 fixes the second shaft structure 400, so that the first shaft 320 and the second shaft structure 400 can keep rotating independently; specifically, because the inner ring and the outer ring of the first inter-shaft fixed bearing 330 can relatively keep independent rotation, the first shaft 320 and the second shaft structure 400 can be mutually independent through the first inter-shaft fixed bearing 330, so that the first shaft 320 and the second shaft structure 400 are free of contact, no friction is generated between the first shaft 320 and the second shaft structure 400, and meanwhile, the position between the first shaft structure and the second shaft structure can be relatively fixed, and meanwhile, because the first end of the second shaft structure 400 is arranged in the second shaft 320, the length of a connecting body of the two shaft structures is reduced.

The first end of the first driven gear 340 is connected to the first shaft 320, the second end is connected to the first motor 100, and the first driven gear 340 controls the first shaft 320 to rotate under the driving of the first motor 100. Specifically, since the first end and the second end of the first driven gear 340 are respectively connected to the first shaft 320 and the first motor 100, the first driven gear 340 drives the first shaft 320 to rotate under the control of the first motor 100 under the driving of the first motor 100, and in the embodiment of the present application, due to the isolation effect of the fixed bearing 330 between the first shafts, the second shaft structure 400 is not driven to rotate when the first shaft 320 rotates;

the first limit 350 is disposed on the first driven gear 340, when the first motor 100 drives the first driven gear 340 to rotate, the first limit 350 is used for controlling a rotation angle of the first driven gear 340, and when the first motor 100 stops operating, the first limit 350 is used for controlling the first driven gear 340 to return to an initial state.

The second driven gear 420 is connected to the second motor 200, and the second motor 200 drives the second driven gear 420 to rotate at a predetermined speed. Specifically, since the first end and the second end of the second driven gear 420 are respectively connected to the second shaft 430 and the second motor 200, the second driven gear 420 drives the second shaft 430 to rotate under the control of the second motor 200 under the driving of the second motor 200, and in the embodiment of the present application, due to the isolation effect of the fixed bearing 330 between the first shafts, the first shaft structure 300 is not driven to rotate when the second shaft 430 rotates. I.e., the rotation of the first shaft structure 300 and the second shaft structure 400 are independent of each other. However, since the first end of the second shaft 430 is deep inside the first shaft structure 300, the length of the combination of the first shaft structure 300 and the second shaft structure 400 is much smaller than the sum of the length of the first shaft structure 300 and the length of the second shaft structure 400, and the mutual independence of the rotation of the two is realized;

the second limit 440 is disposed on the second driven gear 420, when the second motor 200 drives the second driven gear 420 to rotate, the second limit 440 is used to control a rotation angle of the second driven gear 420, and when the second motor 200 stops operating, the second limit 440 is used to control the second driven gear 420 to return to an initial state.
