[0034] Reference Figures 1 to 5 , is a dual output drive device of an embodiment of the utility model, comprising a base 100, a rotation driver 200, two output gear sets 300 and two output shafts 400. The rotation driver 200 is arranged on the base 100; two output gear sets 300 are arranged on the base 100, each of the output gear sets 300 includes a first spur gear 310, a first bevel gear 320 and a second bevel gear 330, the first spur gear 310 is rotatably arranged on the base 100, the rotation axes of the two first spur gears 310 are parallel to each other, the two first spur gears 310 are meshed, the first bevel gear 320 rotates synchronously with the corresponding first spur gear 310, the second bevel gear 330 is meshed with the corresponding first bevel gear 320, the second bevel gear 330 is rotatably arranged on the base 100, the rotation axes of the two second bevel gears 330 are arranged at an angle, and the rotation driver 200 is used to drive one of the output gear sets 300 to rotate; two output shafts 400 are connected to the second bevel gears 330 one by one, and the rotation axis of the output shaft 400 is colinear with the rotation axis of the corresponding second bevel gear 330.

[0035] One of the output gear sets 300 is driven to rotate by a rotation driver 200. When the rotation axes of the two first spur gears 310 are parallel to each other, the two first spur gears 310 are meshed. Since the second bevel gear 330 is driven to mesh by the first bevel gear 320, the rotation axes of the two second bevel gears 330 can be directed in different directions, so that the rotation axes of the two second bevel gears 330 are set at an angle, so that the rotation axes of the two output shafts 400 are set at an angle and rotate in opposite directions, thereby reducing one rotation driver 200 and reducing the manufacturing cost.

[0036] In the embodiment, the rotation axes of the two output shafts 400 are perpendicular to each other. Specifically, the new trash can is suitable for corners, and the rotation axes of the two flaps are at right angles. Therefore, setting the rotation axes of the two output shafts 400 to be perpendicular to each other can more conveniently adapt to drive the two flaps of the new trash can, and the structural adaptability is better. It is conceivable that the angle between the rotation axes of the two output shafts 400 can also be set to other values, such as an acute angle or an obtuse angle, that is, the angle between the rotation axes of the two second bevel gears 330 is set accordingly, and those skilled in the art can make specific configurations according to actual needs.

[0037] In the embodiment, the base 100 is provided with a shaft hole, the output shaft 400 is passed through the shaft hole, and the hole wall of the shaft hole is provided with an oil storage tank 110. Specifically, grease can be stored in the oil storage tank 110, so that during long-term use of the dual-output drive device, the output shaft 400 and the shaft hole can be lubricated, the friction between the output shaft 400 and the base 100 can be reduced, and the dual-output drive device can operate more stably and extend its service life.

[0038] Specifically, the cross section of the oil storage tank 110 is rectangular, and the depth of the oil storage tank 110 can be specifically configured by those skilled in the art according to actual needs.

[0039] In the embodiment, a protrusion 410 is provided on the outer periphery of the output shaft 400, and an annular groove 120 is recessed on the wall of the rotating shaft hole around its central axis, and the protrusion 410 is slidably connected to the annular groove 120. The protrusion 410 is slidably connected to the annular groove 120, so that the position of the output shaft 400 relative to the base 100 in the axial direction is more stable, so that the matching degree of the first bevel gear 320 and the second bevel gear 330 is maintained better.

[0040] Specifically, the protrusion 410 on the outer periphery of the output shaft 400 is an annular protrusion, which has a high structural strength, and the output shaft 400 has good rotation stability.

[0041] In the embodiment, the two first spur gears 310 have the same number of teeth, the two first bevel gears 320 have the same number of teeth, and the two second bevel gears 330 have the same number of teeth, so that the two output shafts 400 can rotate at the same speed in opposite directions, adapting to the two flip covers rotating at the same speed to mate or open, and the structure is simple and easy to implement.

[0042] In the embodiment, a reduction gear set 500 is further included, and the rotary driver 200 is provided with a driving shaft, which is connected to one of the first spur gears 310 through the reduction gear set 500. Usually, the rotary driver 200 has a relatively high driving speed, and the rotary driver 200 is connected to one of the gears of the reduction gear set 500 through the driving shaft, and after deceleration, it drives one of the first spur gears 310 to rotate, and the first spur gear 310 drives the other first spur gear 310 to rotate in the opposite direction, so that the two output shafts 400 can rotate in the opposite direction at a relatively low speed, so as to meet appropriate use needs and achieve better use effects.

[0043] In the embodiment, the base 100 is provided with a receiving cavity, the reduction gear set 500 and the output gear set 300 are both located in the receiving cavity, the rotation driver 200 is connected to the outside of the base 100, the drive shaft is passed through the base 100 and extends into the receiving cavity, and the output shaft 400 is passed through the base 100 and extends into the receiving cavity. The reduction gear set 500 and the output gear set 300 are both in the receiving cavity, and dust from the outside is not easy to enter the reduction gear set 500 and the output gear set 300, thereby reducing the abrasion of the reduction gear set 500 and the output gear set 300 by dust from the outside; the receiving cavity can also be filled with lubricating oil to maintain the lubrication degree of the reduction gear set 500 and the output gear set 300.

[0044] Specifically, the base 100 includes an upper cover, a middle shell and a lower shell, and the upper cover, the middle shell and the lower shell are enclosed to form a receiving cavity. The base 100 is split into the upper cover, the middle shell and the lower shell, which facilitates the assembly between the rotation driver 200, the reduction gear set 500, the output gear set 300 and the output shaft 400 and the base 100, and simplifies the production and assembly difficulty.

[0045] In the embodiment, the reduction gear set 500 includes a plurality of second spur gears meshing in sequence, the rotation axes of the second spur gears, the rotation axes of the first spur gear 310 and the rotation axes of the driving shaft are parallel to each other, and the rotation axes of the output shaft 400 and the rotation axes of the first spur gear 310 are perpendicular to each other. The above structure facilitates the rotation of the driving shaft of the rotary driver 200 after multiple reductions, and then drives the two output shafts 400 to rotate in the opposite direction, and the rotation axis direction of the output shaft 400 does not need to be parallel to the rotation axis direction of the driving shaft, so as to reduce the overall size of the dual output drive device.

[0046] Specifically, the reduction gear set 500 may include two, three or more second spur gears meshing in sequence, and those skilled in the art may configure the specific configuration according to actual needs.

[0047] Specifically, the rotation driver 200 is a motor, which is relatively convenient to use. It is understandable that the rotation driver 200 can also be other structures, such as an electric cylinder that cooperates with a rack and a gear to output rotational power.

[0048] Specifically, one end of the output shaft 400 is plugged into the second bevel gear 330, and the output shaft 400 is fixedly connected to the second bevel gear 330 by screw locking, so that the two rotate synchronously. It is conceivable that the output shaft 400 can also be fixedly connected to the second bevel gear 330 by bonding, so that the two rotate synchronously.

[0049] In the embodiment, a torsion spring 600 is further included. The torsion spring 600 is arranged on the base 100. The base 100 is provided with five plug-in holes 130. A plug-in rod is arranged at one end of the torsion spring 600, and the plug-in rod can be switched and plugged into different plug-in holes 130. When the torsion spring 600 is arranged, when the dual-output drive device is installed on the trash can, the other end of the torsion spring 600 can be connected to the flip cover to apply a certain auxiliary opening force to the flip cover, so that the flip cover opens more smoothly and slows down the closing of the flip cover; and the plug-in rod of the torsion spring 600 can be switched and plugged into different plug-in holes 130 to adjust the elastic force output by the spring, so as to adapt to trash cans with different specifications and requirements, and has a wide range of applications.

[0050] In the embodiment, two connecting rod assemblies 700 are further included. The two connecting rod assemblies 700 are connected to the two output shafts 400 in a one-to-one correspondence. The connecting rod assemblies 700 include a first connecting rod 710 and a second connecting rod 720. One end of the first connecting rod 710 is pivotally connected to one end of the second connecting rod 720. The other end of the first connecting rod 710 is fixedly connected to the corresponding output shaft 400. The other end of the second connecting rod 720 is provided with a pivoting portion. When the dual-output drive device is installed on the trash can, the two output shafts 400 can respectively drive the two flaps of the trash can to rotate through the two connecting rod assemblies 700. The pivoting portion is pivotally connected to the corresponding flap. The output shaft 400 does not need to be aligned with the rotation axis of the flap, and the dual-output drive device can drive the two flaps to rotate with a lower output power, thereby saving the manufacturing cost of the dual-output drive device.

[0051] Specifically, the dual output drive device of the utility model is suitable for the field of trash cans with two flip covers, especially trash cans with rotation axes of the two flip covers forming an angle with each other. It is understandable that the dual output drive device of the utility model can also be used in equipment in other fields.
