Description

Technical Field

[0001] The utility model relates to the technical field of trash cans, in particular to a buffer-covered intelligent trash can. Background Art

[0002] In a traditional smart trash can, the end of the end cap is driven by a driving mechanism, and the free end deflects and covers the opening of the trash can body;

[0003] In the existing technology, the driving mechanism is generally a micro motor, which controls the end cover to open or close the barrel body by setting a preset rotation angle. However, as the working time of the micro motor increases, the mechanical wear increases and the driving accuracy decreases. Over time, the deflection amplitude of the end cover gradually deviates from the preset value. On the one hand, it may cause the free end of the end cover to fail to fit with the opening of the barrel body, causing odor to be emitted from the barrel body. On the other hand, if the driving amplitude of the micro motor is too large, it will cause the end cover and the opening of the barrel body to be squeezed, causing the end cover to deform, which is easy to damage the end cover or the output end of the micro motor, and urgently needs to be improved. Utility Model Content

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a buffer-covered intelligent trash can to solve the problems in the background art.

[0005] In view of this, the present invention provides a buffer-closing smart trash can, including a barrel body, an end cover, and a gear meshing mechanism for rotating the end cover. The gear meshing mechanism includes gear 1 and gear 2 with mutually meshing elliptical structures. Gear 1 and gear 2 are in a meshing state to maintain equal linear speeds. By adjusting the rotation radius ratio R1 / R2 of the meshing positions of the two sets of gears, speed control is used during the closing process of the end cover.

[0006] Preferably, the transmission ratio of the gear 1 to the gear 2 is variable. When the end cover is closed, R1 gradually increases while R2 gradually decreases.

[0007] Preferably, the barrel body is provided with a driving source for driving the gear meshing mechanism, and the driving source is a servo motor or a stepping motor.

[0008] Preferably, the gear meshing mechanism is used to simulate a damping engagement effect.

[0009] Preferably, a mounting groove is provided on one side of the top of the barrel body, and the gear meshing mechanism and the driving source are both arranged in the mounting groove.

[0010] Preferably: the gear meshing mechanism includes a gear 1 that is rotatably connected to the mounting groove via a rotating shaft, the output end of the driving source is fixedly connected to one end of the rotating shaft fixed on the gear 1, the gear 2 is rotatably connected to the barrel body via a rotating shaft fixed on the main body, and the gear 2 is fixedly connected to the end cover.

[0011] A detachable inner barrel is provided inside the barrel body, and a reinforcement ring is fixedly connected to the upper side of the outer wall of the inner barrel.

[0012] A plurality of shape memory alloy spring elements are fixedly connected to the top of the reinforcement ring, and the shape memory alloy spring elements are supported on the bottom of the end cover.

[0013] A handle is rotatably mounted inside the reinforcement ring.

[0014] A solar panel is fixedly mounted on the top of the end cover 2 .

[0015] It can be seen from the above technical solutions that the embodiments of the present invention have the following advantages:

[0016] 1. The buffer-closing intelligent trash can of the utility model utilizes the elliptical structure and variable rotation radius ratio of gear one and gear two to achieve variable speed control during the closing process of the end cover, ensuring that the end cover can be closed smoothly and accurately, greatly reducing the impact and noise during closing.

[0017] 2. This new intelligent trash can with a cushioned lid closes, utilizing a servo motor or stepper motor as its drive source. This not only improves drive precision but also reduces mechanical wear, extending the life of the entire system. The gear meshing mechanism and drive source are integrated into a mounting slot at the top of the can, saving space and facilitating maintenance and cleaning. The removable inner can and handle further enhance ease of use.

[0026] The following is an explanation and description of the technical solutions of the embodiments of the present invention in conjunction with the drawings of the embodiments of the present invention, but the following embodiments are only preferred embodiments of the present invention and are not exhaustive. Based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention.

[0027] The following is a detailed description of the buffer-covered smart trash can according to an embodiment of the present invention with reference to the accompanying drawings.

[0028] Example

[0029] For easier understanding, see Figures 1 to 5 An embodiment of a buffer-closing smart trash can provided by the utility model includes a barrel body 1, an end cover 2, and a gear meshing mechanism for rotating the end cover 2. The gear meshing mechanism includes a gear 1 41 and a gear 2 42 with mutually meshing elliptical structures. The gear 1 41 and the gear 2 42 are in a meshing state to maintain equal linear speeds. By adjusting the rotation radius ratio R1 / R2 of the meshing position of the two sets of gears, speed control is used during the closing process of the end cover 2, thereby replacing the traditional micro-motor direct drive and improving the driving accuracy and system durability.

[0030] In an optional embodiment, the transmission ratio of gear 1 41 to gear 2 42 is variable. When the end cover 2 is closed, as R1 gradually increases and R2 gradually decreases, even if the output angular velocity W2 of the driving source remains constant, the rotational angular velocity W1 of the end cover 2 will also decrease sharply, thereby achieving a smooth and precise closing action of the end cover 2.

[0031] It should be noted that Gear 1 41 and Gear 2 42 adopt an elliptical structure, and by adjusting the rotation radius ratio R1 / R2 between them, variable speed control is achieved during the end cap closing process. This structural arrangement replaces the traditional micro-motor direct drive method, improving drive precision and durability.

[0032] When the end cover is closed, the transmission ratio of gear 1 41 to gear 2 42 is a variable setting. As R1 gradually increases and R2 gradually decreases, even if the output angular velocity W2 of the driving source remains constant, the rotational angular velocity W1 of the end cover will decrease sharply, ensuring that the end cover is closed smoothly and accurately, and preventing deformation or damage caused by collision between the free end of the end cover and the opening of the barrel body.

[0033] In an optional embodiment: a driving source for driving the gear meshing mechanism is provided on the barrel body 1, and the driving source is a servo motor or a stepping motor.

[0034] It should be noted that the driving source of the driving gear meshing mechanism is preferably a servo motor or a stepper motor. Compared with traditional micro motors, this type of motor can provide more precise control torque and position control, reduce mechanical wear, and improve the stability and service life of the entire drive.

[0035] In an optional embodiment: the gear meshing mechanism is used to simulate the damping covering effect, without the need for an additional damping rotation structure, which not only ensures slow deceleration when the end cover 2 is closed, but also overcomes the disadvantage of short life of the traditional damping structure, thereby improving the overall reliability of the product and user experience.

[0036] In an optional embodiment, a mounting groove 3 is provided on one side of the top of the barrel body 1, and the gear meshing mechanism and the drive source are both provided in the mounting groove 3. The gear meshing mechanism and the drive source are integrated in the mounting groove 3 on one side of the top of the barrel body 1, which not only saves space but also facilitates maintenance and debugging.

[0037] In an optional embodiment: the gear meshing mechanism includes a gear 1 41 that is rotatably connected to the mounting groove 3 via a rotating shaft, the output end of the driving source is fixedly connected to one end of the rotating shaft fixed on the gear 1 41, the gear 2 42 is rotatably connected to the barrel body 1 via a rotating shaft fixed on the main body, and the gear 2 42 is fixedly connected to the end cover 2.

[0038] Gear 1 41 is rotatably connected to the mounting slot 3 via a rotating shaft and is fixedly connected to the output end of the driving source; gear 2 42 is rotatably connected to the barrel body 1 via a rotating shaft on the main body and is fixedly connected to the end cover 2, ensuring smooth deceleration when the end cover is closed.

[0039] In an optional embodiment, a detachable inner barrel 5 is provided inside the barrel body 1, and a reinforcement ring 6 is fixedly connected to the upper side of the outer wall of the inner barrel 5. A plurality of shape memory alloy spring elements 7 are fixedly connected to the top of the reinforcement ring 6, and the shape memory alloy spring elements 7 are supported on the bottom of the end cap 2.

[0040] It should be noted that the interior of the trash can 1 is equipped with a removable inner bucket 5, and a reinforcement ring 6 is fixed to the upper side of its outer wall, enhancing the overall structural strength of the trash can. Several shape memory alloy spring elements 7 are fixedly connected to the top of the reinforcement ring 6. These shape memory alloy spring elements 7 provide additional cushioning force when the end cap 2 is closed, cooperating with the variable speed control of the gear meshing mechanism to ensure a soft closing force, improving the closing experience and durability.

[0041] A handle 8 is rotatably mounted within the reinforcement ring 6. This handle 8 facilitates easy removal of the inner bucket 5 for cleaning and waste disposal. A solar panel 9 is fixedly mounted on the top of the end cap 2. This solar panel 9 provides green energy for the smart trash can's electronic components, extending battery life and reducing environmental impact.

[0042] Working principle: When the end cap begins to close, the rotation radius ratio R1 / R2 between gear 1 41 and gear 2 42 will change. As R1 gradually increases and R2 gradually decreases, even if the output angular velocity W2 of the drive source remains constant, the rotation angular velocity W1 of the end cap will slow down, eventually achieving smooth closing of the end cap, avoiding hard collision between the end cap and the barrel opening, and reducing noise and damage. At the same time, a servo motor or stepper motor is used as the drive source. Compared with traditional micro motors, this type of motor can provide more precise control torque and position control, reduce mechanical wear, improve the stability and service life of the entire drive system, and ensure smooth and precise closing of the end cap. The gear meshing mechanism and drive source are integrated in the mounting groove 3 on the top side of the barrel body 1, which not only saves space but also facilitates maintenance and upgrades of the system. Gear 1 41 is connected to the output end of the drive source via a rotating shaft, while gear 2 42 is connected to the barrel body 1 via the rotating shaft on its body and fixed to the end cap 2, ensuring efficient power transmission and smooth deceleration during the closing process.

[0043] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
