Abstract
A drive device of an adjustable desk, which includes a drive shaft and a drive source. The drive shaft is detachably connected to an elevating device of the adjustable desk. The drive source is connected to the drive shaft and is configured to rotate the drive shaft to drive the elevating device, thereby allowing users to drive the adjustable desk manually or electrically.
Description
- The present invention relates to a drive device and, more particularly, to a drive device of an adjustable desk.
- The adjustable desk can be raised and lowered to adjust the height of the desktop according to the needs, and it is becoming more and more popular, especially the children's adjustable desk, which can be adjustable the height of the desktop correspondingly as the child grows, so that the child can maintain a good sitting posture and a good reading distance at every growth stage.
- However, the present adjustable table is limited to be driven in a manual or electric manner, and cannot be changed arbitrarily according to the needs of users.
- In view of the above, a need exists for a novel drive device for an adjustable desk that mitigates and/or obviates the above drawbacks.
- A drive device of an adjustable desk according to the present invention includes a drive shaft and a drive source. The drive shaft is detachably connected to an elevating device of the adjustable desk. The drive source is connected to the drive shaft and is configured to rotate the drive shaft to drive the elevating device.
- In an example, the drive source is an electric motor.
- In an example, the electric motor is arranged within a housing, and the drive shaft extends out of the housing to detachably connect to the elevating device.
- In an example, two sides of the housing are respectively provided with a buckle portion detachably fastened to an adjustable length post of the adjustable desk.
- In another example, the drive source includes a body and a handle. The drive shaft is detachably connected to a first side of the body. The handle is connected to a second side of the body and is adapted to be manually turned to rotate the drive shaft.
- The present invention will become clearer in light of the following detailed description of illustrative embodiments of this invention described in connection with the drawings.
-
FIG. 1 is an exploded, perspective view of a drive device of an adjustable desk of a first embodiment according to the present invention. -
FIGS. 2 and 3 are cross-sectioned views of the drive device ofFIG. 1 . -
FIG. 4 is an exploded, perspective view of a drive device of an adjustable desk of a second embodiment according to the present invention. -
FIGS. 1-3 show a drive device of an adjustable desk of an embodiment according to the present invention. Thedrive device 30 includes adrive shaft 31 and a drive source. Thedrive shaft 31 is detachably connected to anelevating device 20 of the adjustable desk. The drive source is connected to thedrive shaft 31 and is configured to rotate thedrive shaft 31 to drive theelevating device 20. - The adjustable desk mentioned in this embodiment may include an
adjustable length post 10 and theelevating device 20. Theadjustable length post 10 may include a supportingportion 11, a liftedportion 12 telescopically mounted to an upper end of the supportingportion 11, asupport tube 13 arranged within the supportingportion 11, and anut 14 fixed on a top of thesupport tube 13. The liftedportion 12 is connected with a desktop of the adjustable desk. - Further, the
elevating device 20 may include a threadedrod 21, a firsthelical gear 22, and a secondhelical gear 23. The threadedrod 21 is threaded connected to thenut 14 of theadjustable length post 10. The firsthelical gear 22 is fixed on a top of the threadedrod 21. The secondhelical gear 23 is meshed with the firsthelical gear 22 and is detachably connected to thedrive shaft 31 of thedrive device 30. The firsthelical gear 22 can rotate along the first rotation axis, the secondhelical gear 23 can rotate along the second rotation axis, and the first rotation axis and the second rotation axis do not intersect with each other. The threadedrod 21 can be driven by the firsthelical gear 22 to move axially relative to theadjustable length post 10 along the first rotation axis. The helix angles of the firsthelical gear 22 and the secondhelical gear 23 are both 45 degrees. - In addition, The first
helical gear 22 and the secondhelical gear 23 are arranged in agear box 24, and thegear box 24 may be arranged in the liftedportion 12 in this embodiment. A first bearing 25 is provided between the firsthelical gear 22 and a bottom side of thegear box 24. The top of the threadedrod 21 inserts through the first bearing 25 and extends into thegear box 24 to be fixed with the firsthelical gear 22. Twosecond bearings 26 are provided between the secondhelical gear 23 and two side ends of thegear box 24. Thedrive shaft 31 of thedrive device 30 can insert through the second bearing 26 and extend into thegear box 24 to connect with the secondhelical gear 23. - The aforementioned structure of the
adjustable length post 10 and theelevating device 20 is only used to illustrate the function of thedrive device 30 of the adjustable desk, and is not limited to the structure of theadjustable length post 10 and theelevating device 20 in this embodiment. - Furthermore, the drive source may be an
electric motor 32 arranged within ahousing 33 to provide a modular design, and theelectric motor 32 can be driven by internal power supply or external power supply. Thedrive shaft 31 extends out of thehousing 33 to detachably connect to the secondhelical gear 23 of theelevating device 20. Two sides of thehousing 33 are respectively provided with abuckle portion 34 detachably fastened to theadjustable length post 10 of the adjustable desk for fixing thedrive device 30. -
FIG. 4 shows an exploded, perspective view of a drive device of an adjustable desk of a second embodiment according to the present invention. In this embodiment, the drive source includes abody 32 a and ahandle 33 a. Thedrive shaft 31 a is detachably connected to a first side of thebody 32 a, and thehandle 33 a is connected to a second side of thebody 32 a to be adapted to be manually turned to rotate thedrive shaft 31 a. - Thus, the
drive shafts elevating device 20 so that the user can choose to drive the adjustable desk manually or electrically. For example, when theelectric motor 32 is damaged or out of power, it can be manually driven by thehandle 33 a.
