As an important component to ensure the normal use of the seat and the safety of passengers, the performance and reliability of the positioning device of the vehicle seat rotation mechanism are crucial. However, there are certain defects in the existing positioning devices for vehicle seat rotation mechanisms.

[0003] Firstly, in terms of positioning the seat, existing devices often fail to provide sufficient additional support during positioning. This results in all the pressure acting on the support structure during vehicle driving, especially during sudden braking, sharp turning or encountering bumpy road conditions. The seat support structure often has an excessive working intensity, is prone to fatigue damage, and has a shortened service life. This not only increases the costs of maintenance and replacement, but also brings inconvenience to users. Additionally, the existing seat support mechanism has a buffering function when the vehicle jolts. However, due to the lack of corresponding buffering design on the positioning plate, all the pressure may suddenly concentrate on the positioning plate. This not only easily causes problems such as deformation and damage of the positioning plate due to excessive pressure during long-term use, shortening the service life of the positioning device, but also may suddenly fail in extreme cases, posing a serious safety hazard to passengers.

[0004] Therefore, it is necessary to provide a positioning device for a vehicle seat rotation mechanism to solve the above technical problems. Summary of the Utility Model

This device provides additional support while positioning the vehicle seat, effectively sharing the working strength of the support structure and greatly extending the service life of the support structure.

[0021] A buffer spring 18 is fixedly connected between the upper overlapping plate 12 and the lower overlapping plate 14, a damper 19 is installed between the upper overlapping plate 12 and the lower overlapping plate 14, a protection strip 20 is fixedly connected to the bottom of the upper overlapping plate 12, and rubber pads 21 are fixedly connected to the bottom of the protection strip 20 and the bottom of the lower overlapping plate 14. The positioning plate has a buffer function, can effectively disperse and absorb pressure, avoid all the pressure acting on the positioning plate concentratedly, thereby significantly reducing the risk of damage to the positioning plate. The protection strip 20 determines the maximum compression degree of the buffer spring 18 to protect the damper 19 from being squeezed and damaged.

[0022] The seat chassis 4 includes a chassis body 22, four connecting blocks 23 are evenly and fixedly connected to the side of the chassis body 22, a first fastening hole 24 is opened at the top of the chassis body 22, and a seat connecting column 25 is fixedly connected to the top of the chassis body 22.

Therefore, when the rotating chuck 2 rotates, the seat chassis 4 also rotates accordingly.

[0023] Four connecting card slots 26 are evenly arranged on the inner side of the rotating card slot 3. A second fastening hole 27 is arranged inside the rotating card slot 3. A support plate 28 is fixedly connected to the top of the mounting plate 1. The rotating chuck 2 slides on the support plate 28.

[0024] A rotating shaft 29 is fixedly connected to the rotating chuck 2. A motor 30 is arranged at the bottom of the mounting plate 1. The rotating shaft 29 is fixedly connected to the output end of the motor 30. The motor 30 is not in direct contact with the rotating mounting plate 1.

[0026] The working principle of a positioning device for a rotating mechanism of an automobile seat provided by the present utility model is as follows:

[0027] Four positioning mechanisms 5 are respectively installed at the four corners of the mounting plate 1. The synchronous operation of the four cylinders 7 and the telescopic distance of the telescopic rods 8 are controlled by a vehicle-mounted PLC control board. When the seat needs to be rotated, the cylinder 7 is started, the telescopic rod 8 retracts, and the two positioning plates leave the positioning groove 17. The rotating chuck 2 is not restricted and can drive the seat chassis 4 to rotate. Then the seat starts to rotate. After rotating to the designated position, the cylinder 7 is started again, the telescopic rod 8 extends, and the two positioning plates enter the positioning groove 17 for positioning, so that the rotating chuck 2 stops rotating. At the same time, the upper overlapping plate 12 and the lower overlapping plate 14 on the stroke plate 9 move to the bottom of the rotating chuck 2, which can provide additional support force for the seat chassis 4. And a buffer spring 18 and a damper 19 are arranged between the two overlapping plates. When the vehicle encounters a bumpy road section and the buffering function of the support structure is triggered, the buffering function of the lower overlapping plate is also triggered. The potential energy is stored by the buffer spring 18 and then consumed by the damper 19 to buffer the impact force, avoiding sudden damage to the lower positioning plate 13 due to violent pressure and keeping it in good performance.

[0028] Compared with the related technology, a positioning device for a rotating mechanism of an automobile seat provided by the present utility model has the following beneficial effects:

[0029] While positioning the car seat, the device provides additional support, effectively sharing the working intensity of the support structure and greatly extending the service life of the support structure. This reduces the frequency of frequent repairs or replacements of the seat due to fatigue damage of the support structure, saves the maintenance cost of the car owner, and greatly enhances the stability of the seat; the positioning plate has a buffering function, which can effectively disperse and absorb pressure, avoiding all pressure acting on the positioning plate, thus significantly reducing the risk of damage to the positioning plate. Even in the case of long-term use or extreme pressure, the positioning plate can maintain good performance and ensure the normal operation of the seat.
