DETAILED DESCRIPTION

[0022] Example 1

[0023] As Figures 1-2The hand-automatic drawer opening and closing device comprises a drawer 1, a bottom plate 2 arranged at the lower side of the drawer 1, a hand-automatic driving device 3 connected to the top surface of the bottom plate 2 and drivingly connected to the drawer 1. The hand-automatic driving device 3 comprises a driving shaft 31 slidably connected to the top surface of the bottom plate 2, a screw rod 32 threadedly connected to the driving shaft 31 along the axial direction, one end of the screw rod 32 connected to the drawer 1, a sliding gear 33 sleeved on the driving shaft 31, the sliding gear 33 axially slidably connected to the driving shaft 31 and radially drivingly connected to the driving shaft 31. A motor 34 is arranged adjacent to the driving shaft 31 and drivingly connected to the sliding gear 33. The motor 34 drives the sliding gear 33 to rotate, and the sliding gear 33 drives the driving shaft 31 to rotate. The drawer 1 is arranged as a hollow cavity with an open top surface. The end of the driving shaft 31 close to the motor 34 is provided with a limiting groove 312 arranged around the axis of the driving shaft 31. The bottom plate 2 is connected with an electromagnet 4 arranged at the lower side of the driving shaft 31, and the armature of the electromagnet 4 extends into the limiting groove 312. When the drawer 1 is in the closed state and needs to be automatically opened, the armature of the electromagnet 4 extends into the limiting groove 312 to axially limit the driving shaft 31, so as to avoid the driving shaft 31 from moving along the axis when the drawer is automatically opened. When the drawer 1 is in the open state and needs to be automatically closed, the armature of the electromagnet 4 extends into the limiting groove 312 to axially limit the driving shaft 31, so as to avoid the driving shaft 31 from moving along the axis when the drawer is automatically opened. The motor shaft of the motor 34 is connected with a driving gear 341 meshing with the sliding gear 33.

[0024] When the drawer needs to be automatically opened, the armature of the electromagnet 4 extends into the limiting groove 312 close to the motor 34, and then the motor 34 is started. The motor 34 drives the sliding gear 33 to rotate through the driving gear 341, the sliding gear 33 drives the driving shaft 31 to rotate, the driving shaft 31 drives the screw rod 32 to extend, and the drawer is opened. When the drawer needs to be automatically closed, the motor 34 reversely rotates, the motor 34 drives the sliding gear 33 to reversely rotate, the sliding gear 33 drives the driving shaft 31 to reversely rotate, and the driving shaft 31 drives the screw rod 32 to retract, and the drawer 1 is closed. When in the power-off state, the armature of the electromagnet 4 retracts, and when the drawer needs to be manually opened or closed, the user moves the drawer 1, the drawer 1 drives the driving shaft 31 to move through the screw rod 32, the driving shaft 31 slides relative to the sliding gear 33, and the drawer 1 is manually opened. When the drawer needs to be automatically closed, the user moves the drawer 1, the driving shaft 31 slides relative to the sliding gear 33, and the drawer is closed.

[0025] As Figure 3The manual and automatic drawer entry and exit device shown in the figure has a first limit plate 21 and a second limit plate 22 on the top surface of the bottom plate 2, and a sliding gear 33 is rotatably connected between the first limit plate 21 and the second limit plate 22. The first limit plate 21 and the second limit plate 22 support and limit the sliding gear 33 to prevent the axis of the sliding gear 33 from moving. The top surface of the bottom plate 2 is connected to a support platform 23, and the top surface of the support platform 23 is set to an arc shape corresponding to the cross-section of the drive shaft 31, and the drive shaft 31 and the top surface of the support platform 23 are in contact. The drive shaft 31 is slidably connected to the top surface of the support platform 23 to ensure that the drive shaft 31 can be both rotated and moved, and the support platform 23 supports the drive shaft 31. Support blocks 24 are connected to both ends of the bottom plate 2, and guide columns 25 are connected between the support blocks 24 at both ends. There are two or more guide columns 25, and the drawer 1 and the guide columns 25 are slidably connected.

[0026] like Figure 4 In the illustrated manual-automatic drawer entry and exit device, the inner ring of the sliding gear 33 is provided with internal teeth 331, and the internal teeth 331 are arranged in an array around the inner side of the sliding gear 33. The outer side of the drive shaft 31 is provided with external teeth 311, and the external teeth 311 are arranged in an array around the axis of the drive shaft 31. The external teeth 311 and the internal teeth 331 are arranged correspondingly, and the external teeth 311 and the internal teeth 331 are meshed. The sliding gear 33 and the drive shaft 31 are connected by the external teeth 311 and the internal teeth 331. When the sliding gear 33 rotates, the external teeth 311 drive the internal teeth 331 to rotate, which in turn drives the drive shaft 31 to rotate, driving the drawer 1 to move, thereby automatically opening or closing the drawer 1. When the drawer 1 is manually opened or closed, the internal teeth 331 slide along the tooth groove between the two external teeth 311, ensuring that the drawer 1 can be manually opened or closed.

[0027] like Figure 5 In the illustrated manual-automatic drawer entry and exit device, a sliding block 11 and a driving block 12 are connected to the bottom of the drawer 1. The driving block 12 is connected to one end of the drawer 1 and is drivingly connected to a screw 32. The sliding block 11 is located at the end of the drawer 1 away from the sliding block 11. A guide post 25 passes through the sliding block 11 and is slidably connected to the sliding block 11. A distance sensor 13 is installed on the side of the driving block 12 near the sliding block 11. This distance sensor 13 continuously measures the distance between the driving block 12 and the drive shaft 31.

[0028] The distance sensor 13 continuously transmits the detected distance signal to the control system, and the control system controls the motor to start according to the received distance signal. Specifically, when the drawer is in a closed state and the distance between the driving block 12 and the driving shaft 31 becomes larger, the control system starts the electromagnet 4, the armature provided on the electromagnet 4 extends into the limiting groove 312, and the motor 34 is started to drive the drawer 1 to open, that is, when the user manually opens the drawer, the distance sensor 13 senses the change in the distance between the driving block 12 and the driving shaft 31, and the control system starts the motor 34 according to the received distance change signal to assist the user to open the drawer. When the drawer is in an automatic opening state, that is, the screw rod 32 extends out of the driving shaft 31, the distance sensor 13 senses that the distance between the driving block 12 and the driving shaft 31 becomes smaller, the control system starts the electromagnet 4, the armature provided on the electromagnet 4 extends into the limiting groove 312, and then the motor 34 is started to drive the drawer 1 to close.

[0029] The above embodiments are exemplary, and the purpose is to illustrate the technical concept and characteristics of the present application, so that those skilled in the art can understand the content of the present application and implement it accordingly, and the protection scope of the present application cannot be limited thereby. Any equivalent changes or modifications made according to the spirit and essence of the present application shall be covered within the protection scope of the present application.
