Abstract

An electrically-lifted computer desk and office desk thereof, wherein the computer desk comprises a bottom plate, a driving mechanism, an intermediate support member, a first side-support member, a second side-support member and a face plate, wherein the driving mechanism is fixedly disposed on the bottom plate; the face plate is fixedly disposed on the first side-support member and the second side-support member; and the driving mechanism drives the face plate to rise or fold via the intermediate support member, the first side-support member and the second side-support member.

Claims

1. A desk comprising:

a bottom plate;

a first side-support member coupled to the bottom plate;

a second side-support member coupled to the bottom plate;

a face plate coupled to the first side-support member and the second side-support member;

a transverse link coupled to the first side-support member and the second side-support member;

a driving mechanism, the driving mechanism comprising;

a first guide rod;

a second guide rod parallel to the first guide rod;

a screw rod parallel to the first guide rod; and

a driving source configured to rotate the screw rod, and

a nut sliding rod seat coupled to the transverse link with at least one side-support piece, the nut sliding rod seat configured to move along the screw rod,

wherein the driving mechanism is configured to rotate the screw rod moving the nut sliding rod seat to raise and lower the face plate.

2. The desk of claim 1, further comprising:

a first fixing piece; and

a second fixing piece parallel to the first fixing piece,

wherein the first fixing piece, the second fixing piece, the first guide rod, and the second guide rod form a frame.

3. The desk of claim 2, wherein a first end of the screw rod is connected to the first fixing piece and a second end of the screw rod is connected to the second fixing piece, and wherein the driving source is disposed at the first end of the screw rod.

4. The desk of claim 3, wherein the bottom plate is fixed to the first fixing piece and the second fixing piece.

5. The desk of claim 1, further comprising an intermediate support member, the intermediate support member configured to couple the driving mechanism to the first side-support member and the second side-support member.

6. The desk of claim 5, the intermediate support member further comprising the nut sliding rod seat configured to slide along the first guide rod and the second guide rod.

7. The desk of claim 5, the intermediate support member further comprising the nut sliding rod seat, the at least one side-support piece, and the transverse link,

wherein the at least one side-support piece includes a first side-support piece coupled to the nut sliding rod seat and a second side-support piece coupled to the nut sliding rod seat.

8. The desk of claim 7, wherein the first side-support piece includes a lower end pivotally connected with a first end of the nut sliding rod seat, the second side-support piece includes a lower end pivotally connected with a second end of the nut sliding rod seat, and an upper end of the first side-support piece and an upper end of the second side-support piece are fixedly connected with the transverse link.

9. The desk of claim 1, wherein the nut sliding rod seat is coupled to the first guide rod, the second guide rod, and the screw rod, and wherein the nut sliding rod seat is in threaded engagement with the screw rod for reciprocating motion along the first guide rod and the second guide rod upon rotation of the screw rod.

10. The desk of claim 1, wherein the first side-support member and the second side-support member are each slidably coupled to the face plate.

11. The desk of claim 1, wherein the first side-support member and second side-support member each comprise a side-support piece having an upper end and a lower end, wherein the upper end of each side-support piece is pivotally connected to a respective desktop connecting piece fixedly connected with the face plate and wherein the lower end of each side-support piece is pivotally connected to a transverse link.

12. The desk of claim 1, wherein the first side-support member and second side-support member each comprise a side-support piece having an upper end and a lower end, wherein the upper end of each side-support piece is slidably coupled to a respective desktop connecting piece fixedly connected with the face plate and wherein the lower end of each side-support piece is pivotally connected to the bottom plate.

13. The desk of claim 12, further comprising an intermediate support member, the intermediate support member configured to couple the screw rod to the first side-support member and the second side-support member.

14. The desk of claim 13, wherein the intermediate support member comprises the transverse link extending between the first side-support member and the second side-support member.

15. The desk of claim 14, wherein the first side-support member and second side-support member each comprise a second side-support piece having an upper end and a lower end, wherein the upper end of each second side-support piece is pivotally connected to the respective desktop connecting piece fixedly connected with the face plate and wherein the lower end of each second side-support piece is pivotally connected to the transverse link.

16. The desk of claim 14, wherein the intermediate support member further comprises the nut sliding rod seat that slides along the first guide rod and the second guide rod, and is in threaded engagement with the screw rod.

17. The desk of claim 1, wherein the driving source comprises a motor.

18. The desk of claim 1, further comprising a keyboard plate, the keyboard plate coupled with a first desktop connecting piece and a second desktop connecting piece, wherein the first desktop connecting piece and the second desktop connecting piece are fixedly connected to the face plate.
