The correct sitting posture can effectively prevent the occurrence of cervical spondylosis. Therefore, electric lifting tables are designed.

[0003] Existing electric lifting tables usually use motors to drive the table legs to rise and fall. The motors are usually directly installed on the beams, which easily transmits the vibration of the motor when it is working to the table top, causing the table top to vibrate.

[0004] Therefore, how to avoid desktop vibration during the lifting process is a technical problem that needs to be solved urgently in the field. Utility Model Content

[0008] Preferably, a shock-absorbing gap is provided between the side wall of the shock-absorbing groove and the mounting hole.

[0009] Preferably, the mounting hole is a waist-shaped hole.

[0010] Preferably, the supporting crossbeam is a hollow beam, and an outer side wall of the supporting crossbeam is provided with a mounting notch; the lateral end of the mounting member is connected to the inner side wall of the supporting crossbeam by a bolt, and the bolt is arranged in the mounting notch.

[0013] The utility model also provides a lifting table, which comprises a supporting crossbeam; and the lifting table driving mechanism mentioned above.

[0014] The beneficial effects of the utility model are:

[0015] By providing an "L"-shaped mounting piece on the supporting crossbeam and installing the lifting drive assembly on the longitudinal end of the mounting piece, the lifting drive assembly is prevented from being directly installed on the supporting crossbeam, thereby reducing the transmission of vibration of the lifting drive assembly and thus reducing the vibration of the desktop.

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] like Figures 1 to 4 As shown, at least one embodiment provides a lifting table driving mechanism, which is fixed on the supporting beam 1 and includes: a mounting member 11, which is an "L"-shaped sheet metal member, whose lateral end is connected to the side wall of the supporting beam 1, and a lifting driving assembly 3 is installed on the longitudinal end; the lifting driving assembly 3 includes a driving shell 31, and the side wall of the driving shell 31 is provided with a plurality of connecting holes 311; a plurality of mounting holes 111 are provided on the longitudinal end of the mounting member 11, and the mounting holes 111 are connected to the connecting holes 311 by bolts; a shock-absorbing pad 112 is clamped in the mounting hole 111, and a through hole 1121 is opened on the shock-absorbing pad 112; in short, Specifically, an "L"-shaped mounting member 11 is provided on the supporting crossbeam 1, and the lifting drive assembly 3 is installed on the longitudinal end of the mounting member 11, so as to avoid the lifting drive assembly 3 being directly installed on the supporting crossbeam 1, thereby reducing the transmission of vibration of the lifting drive assembly 3 and thus reducing the vibration of the desktop; further, a driving motor is provided in the driving housing 31, which is suitable for driving the active shaft 2, and a connecting hole 311 is provided on the driving housing 31, and a detachable connection of the driving housing 31 can be completed by bolts, and the structure is simple and reliable; further, a shock-absorbing pad 112 is sleeved on the bolt connecting the mounting hole 111 and the connecting hole 311, so as to absorb the radial vibration of the bolt.

[0035] In some embodiments, the side wall of the shock-absorbing pad 112 is provided with an annular shock-absorbing groove 1122, and the shock-absorbing groove 1122 is clamped in the mounting hole 111, and the two end faces of the shock-absorbing groove 1122 are respectively fitted with the side walls of the longitudinal ends of the mounting member 11; in short, the shock-absorbing groove 1122 is clamped in the mounting hole 111, and the two ends of the shock-absorbing pad 112 are respectively fitted with the bolt and the drive housing 31, which can absorb the axial vibration of the bolt, thereby further reducing the transmission of vibration of the lifting drive assembly 3.

The rotation of the screw rod is realized by the rotation of the driving shaft 2, and finally the nut member is driven to move up and down. However, since there are usually errors in the assembly process, there is a deviation between the driving shaft 2 and the position, which may cause deformation of the driving shaft 2 during rotation. By setting the shock-absorbing gap 1123, the driving shaft 2 can drive the drive housing 31 to fine-tune the position and realize self-alignment; further, the shock-absorbing gap 1123 is preferably mm.
