Description

Technical Field

[0001] The utility model belongs to the technical field of automobile armrests, in particular to a central armrest of a passenger car. Background Art

[0002] In the prior art, the armrests on both sides of the central armrest box of the auxiliary instrument panel of the automobile cannot be opened synchronously, the opening speeds are inconsistent, and there is a time difference between the two sides.

[0003] The patent number is CN211617573U, which discloses a utility model patent named "Automobile auxiliary instrument panel and its split armrests". This patent adopts a set of mechanical structures to enable the armrests on both sides to open and close completely synchronously. Although this mechanism can achieve synchronous opening, the armrests cannot be closed individually, the structure is relatively complex, the dimension chain is long, and the gear transmission has high requirements on the processing accuracy of the parts.

[0004] The patent number is CN117231079A, which discloses a utility model patent named "Opening and Closing Connection Mechanism, Armrest Box and Automobile". The transmission assembly of the patent includes a transmission wheel and a connecting rod. The two transmission wheels are connected in transmission and rotate in opposite directions. Although this mechanism can realize synchronous opening, rotation and sliding exist at the same time, and movement may cause stagnation and noise. Utility Model Content

[0005] In view of the above problems, the utility model provides a central armrest of a passenger car, including a first connecting rod, a second connecting rod, a rotating disk, a third connecting rod, a fourth connecting rod and a return spring. The first connecting rod is hinged to one end of the second connecting rod. When the first connecting rod rotates, it can drive the hinge of the second connecting rod to rotate around the rotating axis of the first connecting rod. The other end of the second connecting rod is hinged to one end of the rotating disk, the other end of the rotating disk is hinged to one end of the third connecting rod, and the other end of the third connecting rod is hinged to the fourth connecting rod. When the fourth connecting rod rotates, it can drive the hinge of the third connecting rod to rotate around the rotating axis of the fourth connecting rod. The rotating disk can rotate around itself as the axis driven by the second and third connecting rods. The return torsion spring is installed and sleeved on the rotating disk, one end of which contacts the second connecting rod, and the other end contacts the third connecting rod. The utility model realizes synchronous movement of the armrests on both sides through the connecting rod structure, and is particularly suitable for products with different weights of the armrests on both sides. When the armrests are in the open state, the armrests can be closed on one side.

[0006] The technical scheme of the utility model is as follows: a central armrest of a passenger car, comprising: an armrest box, a first armrest door, a second armrest door and an opening mechanism, the opening mechanism comprising: a first connecting rod, a second connecting rod, a turntable, a third connecting rod, a fourth connecting rod and a return spring, the armrest box is a hexahedron with an opening on one side, the first armrest door and the second armrest door are arranged at the opening of the armrest box, the first armrest door is hinged to the first side wall of the armrest box, the second armrest door is hinged to the side wall opposite to the first side wall, the first connecting rod is fixedly connected to the rotating shaft of the first armrest door, the fourth connecting rod is fixedly connected to the rotating shaft of the second armrest door, and the turntable is fixed on the side wall adjacent to the first side wall of the armrest box.

[0007] Furthermore, the first link is hinged to one end of the second link, and when the first link rotates, it can drive the hinge of the second link to rotate around the rotation axis of the first link. The other end of the second link is hinged to one end of the turntable, and the other end of the turntable is hinged to one end of the third link. The other end of the third link is hinged to the fourth link, and when the fourth link rotates, it can drive the hinge of the third link to rotate around the rotation axis of the fourth link. The turntable can rotate around itself as the axis driven by the second and third links.

[0008] Furthermore, the return torsion spring is installed and sleeved on the rotating disk, with one end in contact with the second connecting rod and the other end in contact with the third connecting rod.

[0009] The beneficial effects of the utility model are:

[0010] 1. The connecting rod structure is used to achieve synchronous movement of the armrests on both sides, which is especially suitable for products with different weights of the armrests on both sides.

[0011] 2. The armrest doors on both sides are equipped with independent rotating shafts and torsion spring mechanisms. They can be closed on one side by pressing, and the turntable can rotate in both directions. When the armrest is open, the armrest can be closed on one side. BRIEF DESCRIPTION OF THE DRAWINGS
