Description

Technical Field

[0001] The utility model relates to the technical field of automobile seats, in particular to an automobile seat armrest frame. Background Art

[0002] At present, with the development of science and technology and the improvement of people's living standards, cars have become an indispensable means of transportation for people to travel, and people have higher and higher requirements for car interior parts. Armrests, as one of the interior parts of cars, play an important role. In order to improve the comfort of car seats, some models have integrated center armrests on the rear seats. Usually, the center armrests of the rear seats are foldable. When the armrests are not needed, they are stored in the backrest of the rear seat. When they are needed, the armrests are laid flat through a flip mechanism. However, the skeleton structure of the existing center armrests takes up a large space for installation, the structural design is complex, the angle adjusters on both sides are inconvenient to arrange, and the overall strength of the skeleton is low. Utility Model Content

[0003] In view of the problems existing in the above-mentioned prior art, the present invention aims to provide a car seat armrest frame to solve the problems of complex structural design and low strength of the existing middle armrest frame.

[0004] In order to achieve the above-mentioned purpose, the utility model proposes a car seat armrest frame, including a frame body and two angle adjusters arranged at the lower end of the frame body, the two angle adjusters are arranged on the inner end of the frame body, one on the left and one on the right, and the two angle adjusters are located on the same axis. The outer ends of the two angle adjusters are fixed with a rotating shaft outward, and the rotating shaft is used to connect with the backrest frame after moving through the frame body. The inner ends of the two angle adjusters are connected to an unlocking rod, and a linkage rod is connected between the two unlocking rods, wherein the unlocking rod of the left angle adjuster is fixed to the left end of the linkage rod by welding, and the unlocking rod of the right angle adjuster is fixed to the left end of the linkage rod by welding. The unlocking rod of the side recliner is square in shape, and the right end of the linkage rod is provided with a square hole matching the corresponding side unlocking rod. The unlocking rod of the right recliner is inserted into the square hole and is in contact with it. An unlocking piece is fixed on the linkage rod, and the unlocking piece is equipped with a cable assembly. The inner ends of the two recliners are also fixedly connected to the skeleton body. Pulling the cable assembly can drive the unlocking piece to rotate, thereby driving the linkage rod to rotate, and then driving the inner and outer ends of the two recliners to produce relative movement to achieve unlocking. After unlocking, the skeleton body can flip around the rotating axis.

[0005] In the above solution, the frame body is fixed inside the armrest shell. The cable assembly includes a cable, an adapter plate, and a drawstring. The right end of the adapter plate is hinged to the frame body, and the left end is connected to the drawstring. The other end of the drawstring extends through the upper front end of the armrest shell. One end of the cable is connected to the end of the unlocking plate away from the linkage rod, and the other end is connected to the middle of the adapter plate. The adapter plate is also equipped with a return spring. The drawstring is exposed at the front end of the armrest shell to facilitate passenger pulling. The first pull unlocks the two recliners, and the second pull flips the armrest downward.

[0006] In the above solution, an arc groove is provided on the adapter plate, and a limit column is provided on the skeleton body. The limit column cooperates with the arc groove to limit the rotation stroke of the adapter plate to avoid excessive tension and damage to the adjuster.

[0007] In the above solution, the frame body is equipped with a rollover buffer device, which includes a gas spring. A gas spring bracket is provided on the left inner wall of the upper portion of the frame body. The gas spring bracket is equipped with a gas spring connecting ball head. A connecting pin is fixed to the outer end of the left recliner. The two ends of the gas spring are movably connected to the gas spring connecting ball head and connecting pin respectively. Traditional rollover mechanisms cannot adjust the rollover speed of the armrest. When the armrest is tilted, the instantaneous impact caused by its own gravity is large, which can easily cause damage to the armrest. This structure realizes the buffering function through the gas spring, effectively solving the above problem.

[0008] In the above solution, both rotating shafts are connected to the backrest frame via rotating shaft brackets, the rotating shaft brackets and the rotating shafts are fixed by welding, and the rotating shaft brackets are fixed to the backrest frame via bolts, which has a simple structure and is easy to assemble.

[0009] In the above solution, the left end of the linkage rod is in an arc-shaped flat shape that matches the outer circle of the unlocking rod of the left recliner. The linkage rod is a hollow rod, and its left end can be flattened to form a shape that matches the outer circle of the unlocking rod.

[0010] The beneficial effects of the present invention are: 1. By arranging the two angle adjusters at the inner end of the frame body, the space occupied by the entire armrest frame is saved, and the structural arrangement is more compact, which improves the structural strength of the armrest frame to a certain extent; 2. If the left and right ends of the linkage rod are fixed to the corresponding unlocking rods by welding, when the welding and fixation of one end has been completed and the welding operation of the remaining end is being carried out, since both ends are rigidly connected, the welding operation can easily cause stress to be generated in the unlocking rod, thereby causing relative movement between the inner and outer ends of the angle adjuster to achieve automatic unlocking; based on this, the present invention welds the left end of the linkage rod to the left unlocking rod, arranges the right unlocking rod in a square shape, and provides a square hole matching the unlocking rod at the right end of the linkage rod, so that the right unlocking rod is in contact with the square hole, thereby avoiding the generation of stress and effectively solving the above-mentioned problem.

The two recliners 2 are coaxially located, and each has a rotating shaft 3 fixed outwardly at its outer end. The rotating shaft 3 flexes through the frame body 1 to connect to the backrest frame.

[0016] The inner ends of the two recliners 2 are connected to an unlocking rod 4, and a linkage rod 5 is connected between the two unlocking rods 4. The unlocking rod 4 of the left recliner 2 and the left end of the linkage rod 5 are fixed by welding, and the unlocking rod 4 of the right recliner 2 is square in shape, and the right end of the linkage rod 5 is provided with a square hole matching the unlocking rod 4 on the corresponding side. The unlocking rod 4 of the right recliner 2 is inserted into the square hole and is in contact with it.

The inner ends of the two adjusters 2 are also fixedly connected to the skeleton body 1. Pulling the cable assembly can drive the unlocking piece 6 to rotate, thereby driving the linkage rod 5 to rotate, and then driving the inner and outer ends of the two adjusters 2 to produce relative movement to achieve unlocking. After unlocking, the skeleton body 1 can flip around the rotating axis 3.

[0018] Ideally, the frame body 1 is fixed within the armrest housing 7. The cable assembly includes a cable 8, an adapter plate 9, and a drawstring 10. The right end of the adapter plate 9 is hinged to the frame body 1, and the left end is connected to the drawstring 10. The other end of the drawstring 10 extends through the upper front end of the armrest housing 7. One end of the cable 8 is connected to the end of the unlocking plate 6 away from the linkage rod 5, and the other end is connected to the middle of the adapter plate 9.
