Referring to fig. 1 to 4, the door assembly according to the embodiment of the present invention includes a first door body 101 and a second door body 102. Wherein, the first door body 101 is formed with a first hidden handle groove 301; the second door body 102 is provided with a second hidden handle groove 201 and is provided with a shielding part 103, and the shielding part 103 is set to be switchable between a concave state and a reset state; the second door body 102 forms an operation avoidance space 202 of a first hidden handle groove 301 and a second hidden handle groove 201 in a recessed state; the shielding member 103 covers the first hidden handle groove 301 and the second hidden handle groove 201 in the reset state.

According to the door assembly of the embodiment of the invention, when the shielding part 103 is in the concave state, the operation avoiding space 202 is formed on the second door body 102, so that a user can select to operate the first hidden handle groove 301 or the second hidden handle groove 201, and the door opening or closing operation of the user is facilitated. When sheltering from part 103 in the reset state, first hidden handle groove 301 and the hidden handle groove 201 of second are hidden and are hidden, and then can't see first hidden handle groove 301 and the hidden handle groove 201 of second from the outside, guarantee that the level and smooth succinct of door subassembly.

When the shielding member 103 is in the recessed state, the first hidden handle slot 301 and the second hidden handle slot 201 are both exposed, and the operation avoiding space 202 can be used for both the operation of the first hidden handle slot 301 and the operation of the second hidden handle slot 201, so that the shielding member 103 is inevitably located between the first hidden handle slot 301 and the second hidden handle slot 201. For example, in fig. 1 to 4, the first hidden handle slot 301 and the second hidden handle slot 201 correspond. Of course, the first hidden handle slot 301 and the second hidden handle slot may be misaligned, as long as the first hidden handle slot 301 and the second hidden handle slot 201 can be opened when the shielding member 103 is in the recessed state.

In general, in the reset state, the shielding member 103 and the second door 102 are completely flush, so as to ensure the flatness of the surface of the door assembly. Of course, it is not excluded that the shielding member 103 and the second door 102 have a certain height difference or the shielding member 103 and the second door 102 are intentionally not flush with each other.

Here, a receiving groove is formed in the second door 102, and the shielding member 103 is mounted in the receiving groove. The holding tank is hidden handle groove 201 intercommunication with first hidden handle groove 301 and second, and at the sunken state, the space is dodged in the operation that the handle groove 201 was hidden to the first hidden handle groove 301 of formation and second in the holding tank.

According to the embodiment of the present invention, the shielding member 103 is connected to a driving member for driving the shielding member 103 to switch between the recess state and the reset state. Under this kind of condition, shelter from part 103 and realize automatic sunkening and automatic re-setting through the drive of driver part, guarantee the convenience of door subassembly operation.

According to an embodiment of the present invention, the door assembly is provided with a sensing part for transmitting a first actuating signal of the driving part when sensing a door opening request operation and transmitting a second actuating signal of the driving part when sensing a door closing demand, the first actuating signal being used to control the driving part to drive the shielding part 103 to move to the recess state, the second actuating signal being used to control the driving part to drive the shielding part 103 to move to the reset state. The door assembly can be opened and closed more simply and more humanized by sensing the specific operation of the user through the arrangement of the sensing part.

According to the embodiment of the present invention, the sensing part for sensing the door opening request operation may be a pressure sensor, an infrared sensor, or another type of sensor. For example, when pressure sensor senses pressure, it means that door assembly senses the operation of requesting to open the door, and then pressure sensor sends first enabling signal this moment, and under first enabling signal's effect, the drive part drive shelters from part 103 and moves to sunken state, and convenience of customers opens the door and operates. For another example, the infrared sensor senses that there is a person near the door assembly, meaning that the door assembly senses a door opening request operation, and then the infrared sensor transmits the first activation signal at this time.

Wherein, when opening the door through pressure sensor response and requesting the operation, pressure sensor can rationally set up based on user's operation habit. For example, a pressure sensor may be disposed at the bottom of the first door 101 and/or the second door 102 in the door assembly, and is convenient for the user to touch by the foot, and then the user touches the position of the door assembly where the pressure sensor is disposed, and the pressure sensor senses the pressure change and sends a first start signal. For another example, a pressure sensor may be disposed at an upper portion of the first door 101 and/or the second door 102 in the door assembly, and is convenient for a user to press with a finger, and then the user presses a position where the pressure sensor is disposed, and the pressure sensor senses a pressure change and sends a first start signal.

In addition, when the door opening request operation is sensed by the infrared sensor, it is possible to judge whether the door opening operation request really exists or not in combination with the movement tendency of the user in order to prevent the erroneous operation. For example, when the infrared sensor senses that the user is stationary near the door body for a first set time period, it is determined that a door opening operation request exists at this time (without additional limitation, the door body in the embodiment of the present invention refers to the first door body 101 and/or the second door body 102); if the infrared sensor senses that the movement speed which is larger than the set speed value exists near the door body of the user, the fact that the user only passes through the door assembly is judged, and the door opening operation request does not exist. The first set time period here may be set to 1 second to 3 seconds, although other suitable values may be selected.

According to the embodiment of the invention, the sensing component for sensing the door closing requirement can also be a pressure sensor, an infrared sensor, or other types of sensors. For example, when pressure sensor senses pressure, it means that the door assembly senses the operation that the demand of closing the door corresponds, and then pressure sensor sends the second start signal this moment, and under the effect of second start signal, the drive part drive shelters from part 103 and moves to the reset state, guarantees to close the level and smooth succinct of the back door body of closing the door. For another example, when the infrared sensor senses that there is no person near the door assembly, it means that the door assembly senses a door closing demand, and then the infrared sensor sends a second activation signal.

Wherein, infrared sensor senses near the door subassembly when not having the people, can set for time length again through the second and just send the second start signal, and then avoid the user to shelter from part 103 automatic re-setting when briefly leaving the door subassembly, convenience of customers' operation. For example, the second set time period may be set to 5 seconds to 15 seconds, but other suitable time periods may be selected based on the operation habit of the user.

Wherein, whether someone sends the second start signal through infrared sensor response door subassembly annex, can realize sheltering from the automatic re-setting of part 103, simplify the control process who shelters from part 103.
