Description

Technical Field

[0001] This utility model belongs to the field of household appliance technology, and specifically relates to an embedded automatic door opening and closing mechanism. Background Technology

[0002] With economic development, more and more household appliances need to add automatic door opening and closing functions to meet the needs of automation, intelligence, and improved customer convenience.

[0003] However, to achieve automatic door opening and closing, many auxiliary components are required. For example, a motor drives a reduction gear mechanism and a clutch gear device, which transmit the driving force to a rack. The automatic opening and closing of the door is then achieved through the cooperation of the locking structure at the front end of the rack and the door lock. This structure is complex, has many external components, and occupies a large area, easily encroaching on the usable space of the cabinet. Furthermore, it is even more difficult to meet the installation requirements for built-in cabinets.

[0004] Therefore, it is necessary to design an automatic door opening and closing mechanism that meets the space requirements of embedded cabinets. Utility Model Content

[0005] Purpose of the utility model: In order to overcome the above shortcomings, this utility model provides an embedded automatic door opening and closing mechanism, which is reasonably designed and simple in structure, and can realize the automatic opening and closing of the cabinet door. Moreover, the embedded design does not take up space and meets the installation conditions of embedded cabinets.

[0006] Technical solution: In order to achieve the above objectives, this utility model provides an embedded automatic door opening and closing mechanism, including a cabinet, a cabinet door, a lead screw, a geared motor, a slider and a connecting rod, wherein the cabinet and the cabinet door are rotatably connected; the cabinet door can rotate around the cabinet to complete the opening and closing action.

[0007] The lead screw is rotatably mounted inside the cabinet door, and a nut is fitted on the lead screw. The lead screw is connected to a reduction motor, which is located inside the cabinet door. The slider is slidably mounted on the cabinet door and is connected to the nut. A first rotating shaft is provided on the slider, and a second rotating shaft is provided on the cabinet body. The two ends of the connecting rod are rotatably connected to the first rotating shaft and the second rotating shaft, respectively.

[0008] The geared motor drives the lead screw to rotate, and the nut that mates with the lead screw moves linearly back and forth along the lead screw, thereby driving the slider to slide. The first rotating shaft on the slider then acts on the connecting rod, and the rotation of the connecting rod acts on the cabinet door, thereby realizing the automatic opening and closing of the cabinet door.

[0009] Furthermore, the cabinet door is equipped with a mounting block, which is a hollow structure with an opening on the side facing the cabinet. A mounting cavity is provided at the top of the cabinet door, and this cavity communicates with the mounting block. The opening on the mounting block can accommodate the connecting rod when the cabinet door is closed, without occupying any other space.

[0010] Furthermore, the lead screw and the geared motor are housed in the mounting cavity, and a sliding groove is provided at the upper part of the mounting cavity. The slider is slidably disposed within this groove, and the first rotating shaft on the slider is located within the mounting block. The lead screw and the geared motor are both housed in the mounting cavity inside the cabinet door, further saving installation space and having no impact on the appearance.

[0011] Furthermore, a bearing is also provided inside the mounting cavity. The bearing is mounted on the side of the mounting cavity via a bearing bracket, and the end of the lead screw facing away from the geared motor is connected to the bearing. The bearing supports the lead screw and enables the lead screw to be rotated during installation.

[0012] Furthermore, the cabinet body and the cabinet door are rotatably connected by hinges.

[0013] Furthermore, the cabinet body is provided with a protrusion, the second rotating shaft is located at the lower part of the protrusion, the mounting block is provided with a groove, and the protrusion is inserted into the groove.

[0014] Furthermore, the nut is equipped with an electromagnet, and the bottom of the slider has a socket into which the electromagnet can be inserted. When energized, the electromagnet is inserted into the socket at the bottom of the slider, connecting the nut and the slider. An infrared ranging sensor is mounted on the nut, which measures the distance between the nut and the slider in real time.

[0015] Furthermore, a trend sensor is installed on the left side of the cabinet door. The trend sensor detects the opening and closing trend of the cabinet door, thereby activating the geared motor.

[0016] As can be seen from the above technical solution, this utility model has the following beneficial effects:

[0017] 1. This utility model provides an embedded automatic door opening and closing mechanism, wherein the transmission mechanism such as the geared motor, slider, slide groove and lead screw are all embedded in the cabinet door panel. After closing, the external connecting rod can also be stored inside the cabinet door, which meets the space requirements of the embedded cabinet, does not require extra space, makes full use of the door space, and does not affect the appearance of the cabinet.

[0018] 2. The door opening and closing mechanism in this utility model meets the requirements of use under both power-on and power-off conditions, without affecting the normal opening or closing of the cabinet door. Under power-on conditions, the slider and nut move as a whole, and under power-off conditions, they separate. Under the action of external force, the slider can slide normally in the groove.

[0019] 3. A trend sensor is installed on the left side of the door. When a hand is detected moving inward or outward, the speed reduction motor will be automatically activated to achieve automatic opening and closing. Attached Figure Description
