Description

Technical Field

[0001] The utility model relates to the technical field of flip mechanisms, in particular to an easy-to-open flip mechanism. Background Art

[0002] As a common household item in daily life, a trash can is used to hold various types of garbage. With the development of society and the progress of technology, trash cans have become increasingly intelligent.

[0003] Existing patent documents, such as the Chinese patent document with the publication number CN112591335A, is an intelligent sorting trash can with a voice-controlled electric push rod. It uses intelligent voice recognition for sorting and an electric push rod to complete household garbage sorting and storage. And based on the principle of infrared induction, the trash can lid automatically opens when a person approaches, and then the garbage is put in. As long as the name of the garbage is spoken, the trash can confirms the type of garbage through voice recognition. After sorting out the garbage type, the garbage tray of the corresponding garbage storage compartment will automatically open, allowing the garbage to fall into the garbage storage compartment, realizing automatic garbage sorting. However, all of the above require the power-on state. If the power is off, the infrared induction cannot be used, and the electric push rod cannot be manually extended and retracted, resulting in the inability to manually open and close the lid. That is, in the prior art, there is a situation where the lid cannot be manually opened and closed when the power is off. Summary of the Utility Model

[0004] Therefore, an easy-to-open flip mechanism is needed to solve the problem of the inability to manually open and close the lid when the power is off.

[0005] To achieve the above object, the utility model provides the following technical solution: An easy-to-open flip mechanism includes a barrel body, a lid, a bracket assembly, a gear motor, a driving gear, a driven gear, a rotating shaft, and a main switch.

The in-place stopper is arranged at the output end of the gear motor, and the gear motor is also used to drive the rotation of the in-place stopper. The in-place switch is used to stop the rotation of the gear motor when touched by the in-place stopper. When the in-place stopper touches the first in-place switch, the lid is in the open state. When the in-place stopper touches the second in-place switch, the lid is in the closed state.

[0007] Further, it further includes an in-place bracket, and the in-place bracket is arranged on the bracket assembly. The first in-place switch and the second in-place switch are respectively arranged on the bracket assembly through the in-place bracket.

[0008] Further, the in-place stopper is sleeved on the output end of the gear motor.

[0009] Further, it further includes a plurality of cylinders, which are dispersedly arranged on the bracket assembly. The in-place bracket is arranged on the bracket assembly through the plurality of cylinders.

[0010] Further, the bracket assembly is arranged on the barrel body through bolt connection or the main switch is a human body induction switch.

[0011] Further, the bracket assembly is dispersedly provided with a plurality of third through holes distributed along the axis of the adaptor shaft, and the shaft passes through the plurality of third through holes to form a rotational connection with the bracket assembly.

[0012] Further, it further includes a plurality of bushings equal in number to the third through holes, which are sleeved on the shaft and located at the rotational connection between the shaft and the bracket assembly.

The gear motor rotates, driving the driving gear to rotate, thereby driving the driven gear to rotate, and then driving the shaft to rotate. The shaft can drive the upper lid to rotate, realizing the opening or closing of the lid. When there is no power, since the gear motor does not restrict the free rotation of the output end when an external force is applied in the case of power-off, when manually opening or closing the lid, the lid can drive the driven gear to rotate, and then drive the driving gear and the gear motor to rotate freely, without hindering the manual opening or closing of the lid, realizing the function of manually opening or closing the lid in the case of power-off.

[0050] Please refer to Figures 1-17 , an embodiment of the present utility model provides an easy-to-open flip cover mechanism, which includes a barrel body 1, a lid 2, a bracket assembly 3, a gear motor 4, a driving gear 5, a driven gear 6, a rotating shaft 7, and a main switch 8. The bracket assembly 3 is arranged on one side of the upper opening of the barrel body 1; the gear motor 4 is arranged on the bracket assembly 3, and a driving gear 5 is sleeved on the output end 41 of the gear motor 4, and the output end 41 of the gear motor 4 is used to drive the driving gear 5 to rotate; the rotating shaft 7 is arranged on the bracket assembly 3 and is rotatably connected to the bracket assembly 3; a driven gear 6 is sleeved on the rotating shaft 7, and the driving gear 5 and the driven gear 6 are engaged with each other; the lid 2 is arranged on the rotating shaft 7; the main switch 8 is arranged on the bracket assembly 3 or the barrel body 1 or the lid 2 and is electrically connected to the gear motor 4. It should be noted that: ① The driving gear 5 and the driven gear 6 are engaged with each other, that is, a gear engagement transmission is formed; ② When the gear motor 4 is powered off, its output shaft can rotate freely under the action of an external force, such as forward rotation or reverse rotation, that is, the internal transmission device of the gear motor 4 does not limit the free rotation of the output shaft in the case of power off.

[0051] Working principle: When there is normal power supply, the main switch 8 controls the gear motor 4 to be powered on, the gear motor 4 rotates, drives the driving gear 5 to rotate, thereby driving the driven gear 6 to rotate, and then driving the rotating shaft 7 to rotate. The rotating shaft 7 can drive the upper lid 2 to rotate, realizing the opening or closing of the lid 2. When there is no power, since the gear motor 4 does not limit the free rotation of the output end 41 when an external force is applied in the case of power off, when manually opening or closing the lid 2, the lid 2 can drive the driven gear 6 to rotate, and then drive the driving gear 5 and the gear motor 4 to rotate freely, without hindering the manual opening or closing of the lid 2, realizing the function of manually opening or closing the lid 2 in the case of power off.

[0052] In some embodiments, it further includes two in-place switches 91 and in-place stoppers 92. The two in-place switches 91 are respectively a first-position switch 911 and a second-position switch 912, which are dispersedly arranged on the bracket assembly 3 and electrically connected to the main switch 8. The in-place stopper 92 is arranged at the output end 41 of the gear motor 4, and the gear motor 4 is further used to drive the rotation of the in-place stopper 92. The in-place switch 91 is used to stop the rotation of the gear motor 4 when touched by the in-place stopper 92. When the in-place stopper 92 touches the first-position switch 911, the lid 2 is in the open state. When the in-place stopper 92 touches the second-position switch 912, the lid 2 is in the closed state. Since the output end 41 of the gear motor 4 drives the rotation of both the driving gear 5 and the in-place stopper 92 at the same time, the rotation angle of the driving gear 5 is the same as that of the in-place stopper 92. The driving gear 5 drives the rotation of the driven gear 6 through meshing transmission, and then drives the rotation of the rotating shaft 7, and further drives the flipping of the lid 2. Therefore, by setting the position of the in-place switch 91, the rotation angle of the in-place stopper 92 can be controlled, and then the reasonable flipping of the lid 2 can be controlled. Such a setting helps to protect the lid 2 and is also more in line with the usage habits.

[0053] In some embodiments, it further includes an in-place bracket 9, and the in-place bracket 9 is arranged on the bracket assembly 3. The first-position switch 911 and the second-position switch 912 are respectively arranged on the bracket assembly 3 through the in-place bracket 9. By installing the in-place bracket 9, the usage space is expanded. The in-place switch 91 is installed on the in-place bracket 9 to better adapt to the in-place stopper 92 in terms of space, realize the function of touching, and is also convenient for maintenance and replacement.

[0054] In some embodiments, the in-place stopper 92 is sleeved on the output end 41 of the gear motor 4. Such a setting helps with disassembly and maintenance.

[0055] Preferably, the in-place stopper 92 is located on the side of the driving gear 5 away from the body of the gear motor 4. Such a setting is more reasonable and more compact.

[0056] Preferably, it further includes a first screw 93. The output end 41 of the gear motor 4 is provided with a threaded hole, and the first screw 93 is threadedly connected to the threaded hole. The cross-sectional area of the head of the screw 93 is larger than the cross-sectional area of the output end 41, and is used to limit the axial sliding of the in-place stopper 92 and the driving gear 5. Specifically, since both the driving gear 5 and the in-place stopper 92 are sleeved on the output end 41 of the gear motor 4, during operation, it is very likely that the driving gear 5 and the in-place stopper 92 will axially slide and disengage from the output end 41, resulting in the gear motor 4 idling and being unable to automatically open and close the lid 2. Therefore, by setting the first screw 93, the axial sliding of the in-place stopper 92 and the driving gear 5 can be limited, and the installation is also made more firm.

[0057] In some embodiments, it further includes a plurality of cylinders 94, which are dispersedly arranged on the bracket assembly 3, and the in-place bracket 9 is arranged on the bracket assembly 3 through the plurality of cylinders 94. By arranging the cylinders 94 and installing the in-place bracket 9, the usable space is expanded.

[0066] In some embodiments, it further includes bushings 71 equal in number to the third perforations 32, sleeved on the rotating shaft 7 and located at the third perforations 32 at the rotational connection between the rotating shaft 7 and the bracket assembly 3. Such a setting helps to reduce the friction and wear at the rotational connection between the rotating shaft 7 and the bracket assembly 3 and reduces the use of lubricating oil.

[0067] In some embodiments, an annular flange 711 is provided on the outer periphery of one end of the bushing 71, and the outer diameter of the annular flange 711 is greater than the inner diameter of the third perforation 32. Due to the provision of the annular flange 711, it can be avoided that during use, the bushing 71 completely enters the third perforation 32 and completely penetrates and slides out of the third perforation 32 along the direction away from the end of the annular flange 711.

Specifically, the number of the snap rings 72 is equal to the number of the bushings 71.

[0070] Optionally, it further includes more than one snap ring 72, sleeved on the rotating shaft 7 and located on both sides of the bushing 71, which helps to prevent the bushing 71 from slipping out of the third perforation 32. Specifically, the number of the snap rings 72 is twice the number of the bushings 71.

[0071] Preferably, the bushing 71 is an oil-free bushing; specifically, the oil-free bushing is an oil-free copper bushing. Such a setting helps to extend the service life.

[0072] Preferably, there are two third perforations 32, which helps to save costs.

[0073] In some embodiments, it further includes a plurality of rotating arms 73. The lid 2 is arranged on the rotating shaft 7 through the plurality of rotating arms 73. One ends of the plurality of rotating arms 73 are dispersedly arranged on the rotating shaft 7, and the other ends are connected to the lid 2. Such a setting helps to adapt to the spatial distribution when the lid 2 and the rotating shaft 7 are connected and also helps with maintenance and replacement.

[0074] Preferably, there are two rotating arms 73, which are respectively arranged at both ends of the rotating shaft 7, helping to save costs.

[0079] Preferably, the induction switch is a human body infrared induction switch. When in use, as long as the human body approaches, the power switch can be realized, facilitating operation.

[0080] Preferably, the main switch 8 is arranged on the side of the bracket assembly 3 away from the barrel body 1. Such a setting is more reasonable and also facilitates operation.

[0081] Preferably, a plurality of lid through holes 21 are arranged on the lid 2 for exhausting air and can also be used as reserved holes for facilitating the installation of other components.
