Further preferably, the two rotating shaft mounting sections are disposed adjacent to each other with the two mounting posts located between the two mounting brackets.

Further preferably, the substrate is provided with a weight-reducing stripe hole.

Further preferably, the damper adopts a fixed torque damper, and the bearing of the table plate is different through selecting the damper without specification.

Further preferably, the rotating motor is a memory motor, and the memory motor has the characteristics of higher mechanical property and light use.

Further preferably, a start switch is provided which is mounted on the back side of the seat back for starting the operation of the rotating motor.

Further preferably, an angle sensor for detecting the rotation angle of the mounting post is also provided.

Further preferably, a circle of protrusions for preventing objects from falling off are arranged on the outer ring of the top surface of the table plate body.

The utility model has the beneficial effects that: the whole structure comprises a base plate, a mounting bracket, a rotating shaft, a rotating motor and a table plate body, and is simple in structure, and the base plate is only required to be mounted on the back side surface of the seat back when being mounted, so that the mounting is convenient, and a space for mounting the table plate is not required to be reserved on the seat back independently; because of the existence of the damper, the resistance of the damper needs to be overcome when the table body rotates, so that the table can be kept at the original position when the rotating motor does not rotate.

Detailed Description

The utility model is further illustrated by the following examples in conjunction with the accompanying drawings:

as shown in fig. 1 to 5, a seat back electric table mainly comprises a table body 1, a base plate 2, a mounting bracket 3, a rotating motor 4, a rotating shaft 5, a mounting column 6 and a damper 7. Wherein the base plate 2 is installed on the seat back and extends left and right, and the interval is provided with two installing support 3 about on the base plate 2, is provided with rotation motor 4 on one of them installing support 3, and rotation motor 4 output shaft level sets up, is provided with the axis of rotation 5 of relative installing support 3 rotation and axis level on another installing support 3. Two cylindrical mounting columns 6 are arranged at left and right intervals at the front end of the bottom surface of the table plate body 1, a damper 7 is embedded in each mounting column 6, and the rotation shaft 5 and the output shaft of the rotation motor 4 are arranged in the damper 7 at the corresponding side.

When the rotary motor rotates, the damping of the damper can be overcome, so that the table plate body is driven to rotate. Because of the presence of the damper, the resistance of the damper needs to be overcome when the table body rotates, so that the table body can be kept in the home position when the rotating motor does not rotate.

To facilitate the installation of the rotation shaft and the rotation motor, the mounting bracket 3 includes two substrate mounting sections 3a and 3b arranged at right angles, wherein the substrate mounting section 3a is arranged on the rear side of the substrate 2, and the substrate mounting section 3a is used for mounting the mounting bracket 3 on the substrate 2.
