Embodiment Construction

[0050] see Figure 4 and Figure 5, the seat electric rotating mechanism shown in the figure includes a rotating bracket 100, a rotating disk 200, a fixed disk 300, a pressure plate 400, an upper ball assembly 500, a lower ball assembly 600, a drive motor assembly 700 and a semicircular rack 800 . The above-mentioned rotating bracket 100, rotating disc 200, fixed disc 300, pressure plate 400, semicircular rack 800, upper ball cage 510 in the upper ball assembly 500, and lower ball cage 610 in the lower ball assembly 600 are all stamped. It has the advantages of high strength and light weight.

[0051] see in conjunction figure 1 , there are 6 M10 nuts 200-1, 200-2, 200-3, 200-4, 200-5, 200-6 spot welded on the rotating disk 200, and the seat cushion frame 900 in the seat is screwed in by 6 Bolts 910 of six M10 nuts 200-1, 200-2, 200-3, 200-4, 200-5, 200-6 are fixedly connected with the rotating disk 200 .

[0052] Eight M8 bolts 310 are spot-welded on the fixed plate 300,...

Abstract

The invention discloses an electric rotation mechanism for a seat. The mechanism comprises a rotation support, a rotation disc, a fixing disc, a press disc, an upper ball assembly, a lower ball assembly, a driving motor assembly and a semi-circular rack. The driving motor assembly is installed on the fixing disc and comprises a driving gear; the semi-circular rack is installed on the rotation support, the circle center of the semi-circular rack coincides with the rotation center of the rotation support, and the semi-circular rack is meshed with the driving gear; the driving gear in the drivingmotor assembly drives the rotation support to rotate back and forth within 0-180 degrees through the semi-circular rack. According to the electric rotation mechanism for the seat, just through single-grade transmission of the driving motor assembly, the driving gear and the semi-circular rack, the seat can rotate back and forth within 0-180 degrees, and the mechanism has the advantage of small occupation space. Meanwhile, the situation is avoided that a wire harness of the seat rotates without limit and is twisted off.

Description

technical field [0001] The invention relates to the technical field of car seats, in particular to an electric rotating mechanism for a seat. Background technique [0002] At present, the rotating mechanism used to rotate the car seat around the vertical axis is divided into two types: rolling rotating mechanism and sliding rotating mechanism according to the different rotating medium. The rolling rotary mechanism uses a plurality of hard balls preset in the cage as the rotating medium to make the rotor rotate in the circular track formed by the upper and lower rows of balls. At present, the rolling rotating mechanism has some technical solutions disclosed in Chinese patents CN103661017B, CN205292658U, CN205632178U, and CN206067762U. These technical solutions have the following problems: 1. The structure is complex and the number of parts is large; 2. Multi-stage transmission takes up a lot of space; 3. Non-modularization makes it inconvenient to apply different seat frame...
