Abstract

The present application relates to the field of storage technology, and provides a door assembly and a storage cabinet. The door assembly includes a door body provided with a handle groove; a driving assembly; a rack hinged to the door body and provided with a cover plate assembly; and a first detecting member configured to generate a first detecting signal; where the driving assembly is adapted to drive the rack to switch between a pressing state and a resetting state based on the first detecting signal; and in the pressing state, the cover plate assembly avoids the handle groove, and in the resetting state, the cover plate assembly shields the handle groove.

First claim

What is claimed is:

1. A door assembly, comprising:
a door body, provided with a handle groove;
a driving assembly;
a rack, hinged to the door body and provided with a cover plate assembly; and
a first detecting member, configured to generate a first detecting signal,
wherein the driving assembly is configured to drive the rack to switch between a pressing state and a resetting state based on the first detecting signal, in the pressing state, the cover plate assembly offset from the handle groove, and in the resetting state, the cover plate assembly shielding the handle groove; and
wherein the rack includes a swiveling rack, the swiveling rack including:
a driving shaft hinged to the door body;
a first driven shaft hinged to the cover plate assembly; and
a first transition connecting member, connected between the driving shaft and the driven shaft; and

wherein the driving assembly includes a motor mounted on the door body and connected to the driving shaft.

2. The door assembly of claim 1 , wherein the swiveling rack comprises:
a first swiveling rack, wherein a first end of the first swiveling rack is hinged to the door body, and a second end of the first swiveling rack is hinged to the cover plate assembly; and
a second swiveling rack, wherein a first end of the second swiveling rack is hinged to the door body, and a second end of the second swiveling rack is hinged to the cover plate assembly,
wherein the driving assembly is configured to drive one or more of the first swiveling rack or the second swiveling rack, to move the cover plate assembly in a direction perpendicular to the door body.

3. The door assembly of claim 2 , wherein the first swiveling rack comprises:
a first driving shaft, wherein two ends of the first driving shaft are hinged to the door body;
a first driven shaft, wherein two ends of the first driven shaft are hinged to the cover plate assembly; and
a first transition connecting member, connected between the first driving shaft and the first driven shaft; and
the second swiveling rack comprises:
a second driving shaft, wherein two ends of the second driving shaft are hinged to the door body;
a second driven shaft, wherein two ends of the second driven shaft are hinged to the cover plate assembly; and
a second transition connecting member, connected between the second driving shaft and the second driven shaft.

4. The door assembly of claim 3 , wherein the first transition connecting member is positioned at one or more of the first driving shaft or the first driven shaft through a first limiting structure; and
the second transition connecting member is positioned at one or more of the second driving shaft or the second driven shaft through a second limiting structure.

5. The door assembly of claim 3 , wherein the motor of the driving assembly is connected to one or more of the first driving shaft or the second driving shaft.

6. The door assembly of claim 5 , wherein the motor is connected to one or more of an end of the first driving shaft or an end of the second driving shaft through a shaft coupling; or
the motor is connected to one or more of the first driving shaft or the second driving shaft in a transmission manner through a transmission assembly.

7. The door assembly of claim 3 , wherein the driving assembly comprises the motor and an elastic member;
wherein the motor is connected to one or more of the first driving shaft or the second driving shaft; and
the elastic member is sleeved on the first driving shaft, and two ends of the elastic member abut against the door body and the first transition connecting member respectively; or
the elastic member is sleeved on the second driving shaft, and two ends of the elastic member abut against the door body and the second transition connecting member respectively.

8. The door assembly of claim 3 , wherein the driving assembly comprises a magnetic member, wherein the magnetic member is mounted on the door body, and the magnetic member is configured to drive the rack to switch between the pressing state and the resetting state based on the first detecting signal.

9. The door assembly of claim 1 , further comprising a second detecting member, wherein the second detecting member is mounted on the door body, and the second detecting member is configured to generate a second detecting signal for controlling the motor to stop after detecting that the rack switches to the resetting state.

10. The door assembly of claim 9 , wherein the driving shaft is sleeved with a swing rod, and in the resetting state, the swing rod is configured to trigger the second detecting member to generate the second detecting signal.

11. The door assembly of claim 9 , wherein the door body is provided with a mounting plate, the motor is mounted on the mounting plate, and a shock pad is provided between the mounting plate and the motor;
wherein an output shaft of the motor is connected to an end of the driving shaft through a shaft coupling; or
the output shaft of the motor is connected to the first driving shaft in a transmission manner through a transmission assembly.

12. The door assembly of claim 3 , wherein one or more of the first transition connecting member or the second transition connecting member is limited at the door body through a groove side wall of the handle groove, to prevent the one or more of the first transition connecting member or the second transition connecting member from disengaging from the door body.

13. The door assembly of claim 3 , wherein the cover plate assembly comprises:
a cover plate base, wherein two ends of the first driven shaft and two ends of the second driven shaft are hinged to the cover plate base respectively; and
a cover plate body, mounted on the cover plate base.

14. The door assembly of claim 13 , further comprising a light bar, wherein the cover plate base is provided with a mounting space for mounting the light bar, and the cover plate body is provided with a light transmission area at a position corresponding to the light bar.

15. The door assembly of claim 3 , wherein the door body comprises a supporting base, and the handle groove is provided on the supporting base; and
the first end of the first swiveling rack and the first end of the second swiveling rack are hinged to the supporting base, and the second end of the first swiveling rack and the second end of the second swiveling rack are hinged to the cover plate assembly.

16. The door assembly of claim 15 , wherein the door body further comprises a mounting base, and the supporting base is mounted on the mounting base.

17. A storage cabinet, comprising a body and a door assembly coupled to the body, the door assembly including:
a door body, provided with a handle groove;
a driving assembly;
a rack, hinged to the door body and provided with a cover plate assembly; and
a first detecting member, configured to generate a first detecting signal,
wherein the driving assembly is configured to drive the rack to switch between a pressing state and a resetting state based on the first detecting signal, in the pressing state, the cover plate assembly offset from the handle groove, and in the resetting state, the cover plate assembly shielding the handle groove;
wherein the rack includes a swiveling rack, the swiveling rack including:
