[0002] As people's living standards improve, consumers' expectations for car interiors are becoming increasingly demanding, requiring greater comfort and a sense of technology. As a crucial interior component, car armrests now feature dual-opening options. These armrests, with a single button controlling the opening of both arms, experience a definite impact on the synchronization of the armrests' opening due to the different torsion spring torques on the left and right sides, which reduces the user experience.

[0012] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0013] See also Figure 1-3 The utility model provides the following technical solutions: a synchronous adjustment structure of a split armrest, which is installed on the armrest, including a hanging turntable 1, a turntable mounting base 2 and a torsion spring 3. A limit column 21 is provided in the middle of the turntable mounting base 2, and a hollow column 14 is provided in the center of the hanging turntable 1. The hollow column 14 is movably sleeved on the limit column 21. The hanging turntable 1 can rotate clockwise or counterclockwise on the turntable mounting base 2. A plurality of hanging points 11 are evenly spaced around the hanging turntable 1. The torsion spring 3 is installed on the turntable mounting base. Below the base 2, an upwardly extending force arm is provided on one end of the torsion spring 3, and the force arm on the torsion spring 3 is just hung on a hanging point 11. Support ribs 12 are provided between several hanging points 11 and the hollow column 14. The height of the support rib 12 is less than the height of the hanging point 11 and the hollow column 14. The height of the force arm on the torsion spring 3 hanging on the hanging point 11 is controlled by the support rib 12. The height of several support ribs 12 gradually increases in the clockwise direction, and the upward tilt angle of the force arm on the torsion spring 3 increases as the height hanging on the support rib 12 increases. The main part of the torsion spring 3 is installed on the armrest, and the force arm on the torsion spring 3 is hung on the hanging point 11, and the height of the hanging point 11 is the height of the supporting rib 12. After the torsion spring 3 is installed on the armrest and the hanging point 11, there is a thrust to open the armrest. When the force arm of the torsion spring 3 is hung on the hanging point 11 corresponding to the supporting rib 12 with a low height, the thrust to the armrest is small, and the armrest takes a long time to fully open. When the force arm of the torsion spring 3 is hung on the hanging point 11 corresponding to the supporting rib 12 with a high height, the thrust to the armrest is large, and the armrest takes a short time to fully open. Therefore, several hanging points 11 are divided into different gears, and the gears of the hanging points 11 gradually increase in the order of the height of the supporting rib 12 from low to high. After rotating the hanging point turntable 1, it is adjusted to the appropriate gear so that the armrest opens synchronously, thereby improving the user experience.

[0014] Specifically, a guide limit groove 13 is opened in the middle of the bottom surface of several hanging points 11, and a plurality of guide limit ribs 22 matching the guide limit groove 13 are provided on the surface of the turntable mounting base 2. After rotating the hanging point turntable 1 to the appropriate gear, the guide limit rib 22 is in the guide limit groove 13, and the hanging point turntable 1 will not rotate, thereby ensuring the accuracy of the gear position of the hanging point 11.

[0015] Specifically, the number of the hanging points 11 , the supporting ribs 12 , the guide limiting grooves 13 and the guide limiting ribs 22 is the same.

[0016] Specifically, when the number of hanging points 11 is 4, the upward tilt angle of the force arm on the torsion spring 3 increases by 5° as the height of the hanging on the support rib 12 increases by one level, and is divided into four levels A, B, C and D from low to high.

[0017] The movement process of the utility model is: when it is necessary to adjust the synchronization adjustment structure of the split armrests, first rotate the hanging point turntable 1 clockwise or counterclockwise to the appropriate gear position. At this time, the guide limit rib 22 is limited in the guide limit groove 13, and the hanging point turntable 1 cannot rotate. Just hang the force arm of the torsion spring 3 on the hanging point 11.

[0018] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
