Description

Technical Field

[0001] The utility model belongs to the technical field of garbage collection devices, and in particular relates to a double-door automatic small cover opening transmission mechanism and an intelligent garbage can. Background Art

[0002] In order to make it more convenient to put out garbage and change garbage bags, smart trash cans are often equipped with a large cover and a small cover. The large cover is located above the barrel of the trash can, and the small cover is rotatably connected to the large cover. There are multiple transmission mechanisms inside the cover, which can automatically open or close to achieve a smart effect.

[0003] Among them, in the transmission mechanism for opening and closing the small cover, the conventional practice is to use gears or racks to realize transmission. For example, in the utility model patent "A lid opening mechanism for a trash can" with publication number CN218752723U, a motor is used to drive, and a cam, a drive rod gear, a reduction gear set, etc. are set to realize the opening or closing of the small cover. The high cost of the gears leads to high production costs of the trash can; and the gear assembly is difficult, which is not conducive to later maintenance; at the same time, the two small covers in the patent are driven to open and close by different transmission mechanisms, which is easy to cause the phenomenon of drive asynchronism, and the transmission reliability of the opening and closing of the small covers is not high.

[0004] Therefore, it is necessary to design a double-door automatic small cover transmission mechanism and apply it to the smart trash can to solve the above technical problems. Utility Model Content

A first rotating connecting plate is provided below the rotating end of the first small cover, and a motor shaft fixing hole and a first connecting hole are provided on the first rotating connecting plate.

[0008] One end of the second small cover is a rotating end, and the other end away from the rotating end is a driven end. A second rotating connecting plate is provided below the rotating end of the second small cover, and a rotating hole and a second connecting hole are provided on the second rotating connecting plate.

[0009] One end of the connecting rod is installed in the first connecting hole, and the other end is installed in the second connecting hole;

[0010] The output shaft of the motor is installed in the motor shaft fixing hole, and the rotating hole is installed on the external fixing frame through the rotating shaft; the driven end of the first small cover and the driven end of the second small cover are also installed on the external fixing frame respectively.

[0011] Furthermore, the motor shaft fixing hole is a blind hole, a coupling is clamped and installed in the motor shaft fixing hole, and the output shaft of the motor is installed in the motor shaft fixing hole through the coupling.

[0012] Furthermore, a first driven connecting plate is provided below the driven end of the first small cover, a first rotating shaft hole is provided on the first driven connecting plate, and the first driven connecting plate is mounted on the external fixed frame through the first rotating shaft hole.

[0013] Furthermore, a second driven connecting plate is provided below the driven end of the second small cover, a second rotating shaft hole is provided on the second driven connecting plate, and the second driven connecting plate is mounted on the external fixed frame through the second rotating shaft hole.

[0018] (1) The double-door automatic small cover opening transmission mechanism of the utility model simplifies the transmission structure and only requires one connecting rod to realize the opening and closing of the small covers on both sides. It has a simple structure, low assembly difficulty, and reduces production costs.

[0019] (2) The double-door automatic small cover opening transmission mechanism of the utility model can realize the synchronous and reliable transmission of the small covers on both sides through the transmission of a connecting rod, and the reliability of the opening and closing of the small covers is high, and the quality of the whole machine is also improved.

[0033] In a specific embodiment, the motor shaft fixing hole 6 is a blind hole, and a coupling 11 is clamped and installed in the motor shaft fixing hole 6 . The output shaft of the motor 3 is installed in the motor shaft fixing hole 6 through the coupling 11 .

[0034] In other embodiments, the motor shaft fixing hole 6 may also be a through hole, and the connection method of the output shaft of the motor 3 is the same as above.

[0035] The motor 3 is mounted on the external fixed frame; similarly, the rotating hole 9 is also mounted on the external fixed frame through a rotating shaft; in addition, a first driven connecting plate 12 is provided below the driven end of the first small cover 1, and a second driven connecting plate 14 is provided below the driven end of the second small cover 2, a first rotating shaft hole 13 is provided on the first driven connecting plate 12, and the first driven connecting plate 12 is mounted on the external fixed frame through the first rotating shaft hole 13, and a second rotating shaft hole 15 is provided on the second driven connecting plate 14, and the second driven connecting plate 14 is mounted on the external fixed frame through the second rotating shaft hole 15. Specifically, the external fixed frame is the large cover of the trash can.

[0036] In a specific embodiment, the first small cover 1 and the second small cover 2 are both rectangular in shape, the rotating end of the first small cover 1 is arranged on the same side as the rotating end of the second small cover 2, and correspondingly, the driven end of the first small cover 1 is arranged on the same side as the driven end of the second small cover 2.

[0037] In other embodiments, the shapes of the first small cover 1 and the second small cover 2 may also be circular, elliptical, triangular, polygonal, irregular, etc.; and the shapes of the first small cover 1 and the second small cover 2 may be the same or different, as long as the first small cover 1 and the second small cover 2 can completely cover the garbage placement hole of the large cover of the trash can when they are closed.

[0038] In a specific embodiment, the widths of the first small cover 1 and the second small cover 2 are different, the width of the first small cover 1 is smaller than the width of the second small cover 2, and the motor 3 is connected to the first small cover 1; in other embodiments, the widths of the first small cover 1 and the second small cover 2 are the same, and the motor 3 is connected to any one of the small covers.

[0039] The above-mentioned double-door automatic small cover opening transmission mechanism can be applied to the large cover part of the intelligent trash can to form a small cover mechanism for throwing garbage.

[0040] Working principle: When the double-door automatic small cover transmission mechanism of the utility model is working, its action process is as follows:

[0041] When opening the cover, the motor 3 is started, and the output shaft of the motor 3 drives the coupling 11 and the first rotating connecting plate 5 to rotate in sequence, thereby driving the first small cover 1 to rotate outward around the motor shaft fixing hole 6 and open; at the same time, the first rotating connecting plate 5 drives the connecting rod 4 and the second rotating connecting plate 8 to rotate, thereby driving the second small cover 2 to rotate outward around the rotating hole 9 and open. The driven ends of the first small cover 1 and the second small cover 2 rotate synchronously to complete the opening action of the small cover.

[0042] When closing the cover, the motor 3 starts to rotate in the reverse direction, and the output shaft of the motor 3 drives the coupling 11 and the first rotating connecting plate 5 to rotate in turn, thereby driving the first small cover 1 to rotate inward around the motor shaft fixing hole 6 to close; at the same time, the first rotating connecting plate 5 drives the connecting rod 4 and the second rotating connecting plate 8 to rotate, thereby driving the second small cover 2 to close inward around the rotating hole 9. The driven ends of the first small cover 1 and the second small cover 2 rotate synchronously to complete the closing action of the small cover.

[0043] The double-door automatic opening and closing small cover mechanism of the utility model comprises a motor, a transmission rod and small covers on both sides. The motor 3 directly drives the first small cover 1, and the first small cover 1 drives the second small cover 2 through the connecting rod 4, which simplifies the transmission structure (reduces the number of connecting rods 4), increases the reliability of the transmission, simplifies the assembly difficulty, and thus improves the reliability of the opening and closing of the small covers, while also achieving a mute effect.

[0044] The above are only preferred embodiments of the utility model and are not intended to limit the utility model. Any modifications, equivalent substitutions, improvements, etc. made within the design concept of the utility model should be included in the protection scope of the utility model.
