[0032] Reference Figures 1 to 4 , a cabinet, comprising: a cabinet body 110, which is a cavity-type structure with one side open;

[0033] The cabinet door 100 is hinged to the top of the cabinet body 110 to form a closed accommodating cavity;

[0034] The cabinet opening unit includes a power assembly 160 and a transmission assembly 150. The power assembly 160 is installed in the cabinet body 110. One end of the transmission assembly 150 is transmission-connected to the power assembly 160, and the other end is transmission-connected to the cabinet door 100. The power assembly 160 drives the cabinet door 100 to move toward or away from the center of the accommodating cavity through the transmission assembly 150.

[0035] The controller is electrically connected to the power assembly 160 , and is used to control the operation of the power assembly 160 .

[0036] The cabinet body 110 and the cabinet door 100 are hinged to each other through the top. Different from the cabinets that open on the left and right sides, the cabinet door 100 that opens on the top can save space, improve space utilization, and is more convenient to install, which can improve the adaptability of the cabinet; the power component 160 set in the cabinet can provide power for the cabinet door 100 when opening and closing, and the transmission component 150 can transmit the power of the power component 160 to the cabinet door 100, so as to realize the automatic opening or closing of the cabinet door 100; the controller can control the action of the power component 160, so as to improve the human-computer interaction, thereby further improving the convenience of using the cabinet; the cabinet that can open and close automatically can make full use of the kitchen space and improve the utilization of space. Even if the cabinet door 100 is in a higher position after opening, the power component 160 can retract the cabinet door 100, which is convenient for people of different heights to use.

[0037] The cabinet body 110 includes a top plate, a bottom plate, a back plate, a first side plate and a second side plate. When the cabinet door 100 is closed, it can form a relatively closed accommodating cavity with the cabinet body 110 .

[0038] It is understandable that the controller can use wireless transmission signals, such as Bluetooth, infrared, WIFI, etc. to control the operation of the power assembly 160. In some embodiments, a start signal is sent to the controller through a remote controller 280, and the remote controller 280 is detachably adsorbed on the bottom plate of the cabinet through a magnet, and the trigger part of the remote controller 280 slightly protrudes from the bottom plate. When the cabinet door 100 needs to be opened electrically, it is only necessary to press the position of the cabinet door 100 corresponding to the trigger part to trigger the remote controller 280. The remote controller 280 sends a start signal to the controller to open the cabinet door 100 automatically. When the cabinet door 100 needs to be closed, the trigger part can also be directly pressed to close the cabinet door 100 automatically.

[0039] Reference Figures 1 to 3The transmission assembly 150 includes a connecting rod group, and the power assembly 160 includes a motor 180. One end of the connecting rod group is connected to the motor 180 for transmission, and the other end is connected to the cabinet door 100. The motor 180 runs to drive the connecting rod group to swing. The motor 180 is used for driving, which is quiet, has low noise, and is easy to install. The motor 180 is used to directly drive the connecting rod group for transmission, which has a simple structure and can convert the rotational motion of the motor 180 into a swinging motion, thereby realizing the actions of opening and closing the cabinet door 100.

[0040] The transmission assembly 150 includes a first gear 210 and a second gear 240 that mesh with each other. The first gear 210 is connected to the motor 180, and the second gear 240 is connected to the connecting rod assembly. The diameter of the second gear 240 is larger than the diameter of the first gear 210. Transmission through the large-diameter second gear 240 can increase the torque, adapt to cabinet doors 100 of different models and sizes, and further improve the adaptability of the cabinet. In some preferred embodiments, the ratio of the diameter of the second gear 240 to the diameter of the first gear 210 is greater than 3:1. By setting a larger transmission ratio, the output speed of the motor 180 can be effectively reduced, thereby increasing the torque. When the weight of the cabinet door 100 is relatively large, the cabinet door 100 can also be successfully raised or closed to ensure that the cabinet door 100 can be successfully opened or closed.

[0041] The output shaft of the motor 180 is connected to the worm 190, and the cabinet 110 is rotatably mounted with a first shaft 220, one end of the first shaft 220 is passed through the middle of the first gear 210 and fixed to the first gear 210, and the other end is fixedly mounted with a worm wheel 200, which is meshed and connected with the worm 190. The use of worm gear transmission can achieve self-locking, avoid danger caused by sudden power failure of the motor 180, and the worm gear transmission is stable and has low noise.

[0042] Reference Figure 5 In some preferred embodiments, a one-way drive turntable 290 is provided between the first gear 210 and the worm gear 220. The one-way drive turntable 290 is composed of a magnet, a ball and a hexagonal cam. The one-way drive turntable 290 can ensure that power is only transmitted from the worm gear 180 to the first gear 210. When the first gear 210 rotates, it will not drive the worm 190 to rotate, which can avoid damage to the motor 180 when the cabinet door 100 is manually opened and closed.

[0043] Reference Figure 4A second shaft 230 is rotatably installed in the cabinet body 110, an angle sensor 270 is passed through one end of the second shaft 230, and a second gear 240 is fixedly installed on the other end, and the angle sensor 270 is electrically connected to the controller. The second shaft 230 rotates coaxially with the angle sensor 270, and the angle sensor 270 obtains the current posture of the cabinet door 100, so as to facilitate the adjustment of the output of the power component 160, and avoid damage to the cabinet opening unit caused by excessive opening of the cabinet door 100. In daily use, if the cabinet door 100 is opened halfway by hand, the angle sensor 270 can obtain the posture of the cabinet door 100, thereby judging the current angle of the cabinet door 100, so as to control the output of the power component 160 and ensure that the cabinet door 100 can be opened or closed stably.

[0046] A hydraulic support rod 120 is provided between the cabinet door 100 and the cabinet body 110, the fixed end of the hydraulic support rod 120 abuts against the cabinet door 100, and the free end of the hydraulic support rod 120 abuts against the cabinet body 110. The hydraulic support rod 120 can ensure the stable opening and closing of the cabinet door 100, and can adjust the resistance when the cabinet door 100 is opened, so as to achieve the function of hovering support. The hydraulic support rod 120 can also achieve the effect of hovering. When the cabinet door 100 is opened manually, the hydraulic support rod 120 can support the cabinet door 100, and after the external force is removed, the cabinet door 100 can still remain in the open state.

[0047] There are two groups of hydraulic support rods 120, and the two groups of hydraulic support rods 120 are symmetrically arranged in the accommodating cavity. The two groups of hydraulic support rods 120 arranged symmetrically can further improve the stability of the cabinet door 100 when opening and closing. In some preferred embodiments, the two groups of hydraulic support rods 120 are respectively arranged on the first side plate and the second side plate, which can balance the force.

[0048] Reference Figure 1 and Figure 2The hydraulic support rod 120 is provided with a buffer 130, and the buffer 130 is arranged toward the cabinet body 110. When the cabinet door 100 is closed, the buffer 130 abuts against the side wall of the cabinet body 110. The buffer 130 can reduce the impact between the cabinet door 100 and the cabinet body 110 when the cabinet door 100 is closed, thereby increasing the service life of the cabinet and avoiding a hard collision between the cabinet door 100 and the cabinet body 110. The buffer 130 can be a hydraulic buffer 130. When the cabinet door 100 is closed, the trigger head of the hydraulic buffer 130 abuts against the first side plate or the second side plate. The hydraulic buffer 130 can make the cabinet door 100 close smoothly, further improving the user experience.
