Description

Technical Field

[0001] The invention relates to the technical field of automobile seats, and in particular to an automobile armrest structure capable of realizing smooth flipping. Background Art

[0002] In order to improve the comfort of car seats, some models integrate a middle armrest on the rear seats. Usually, the middle armrest of the rear seat is foldable. When the armrest is not needed, it is stored in the backrest of the rear seat; when the armrest is needed, the armrest is laid flat through the flip mechanism. The traditional flip mechanism cannot adjust the flipping speed of the armrest. When the armrest is laid down, the instantaneous impact caused by its own gravity is large, which is inconvenient to operate and easily causes damage to the armrest. In addition, the traditional flip mechanism has poor stability, and the locking mechanism thereon also has problems such as low locking strength, complex structure, and inconvenient operation. Summary of the invention

[0003] In view of the problems existing in the above-mentioned prior art, the present invention aims to provide a car armrest structure that can achieve smooth flipping, so as to solve the problems of poor stability, low locking strength and large impact force during flipping of the traditional flipping mechanism.

[0004] In order to achieve the above-mentioned purpose, the present invention proposes a car armrest structure that can achieve smooth flipping, including an armrest assembly and a backrest connecting bracket used to be connected to a backrest frame, and also including a rotator assembly and a cable assembly. The rotator assembly includes two coaxially arranged rotators, the outer ends of the two rotators are respectively fixedly connected to the backrest connecting bracket through rotating shafts, and the two rotating shafts are located on the same axis. The lower end of the armrest assembly is hinged on the two rotating shafts and clamped with the inner ends of the two rotators, and the inner ends of the two rotators are connected by an unlocking rod, and the unlocking rod and the rotator are located on the same axis. A cable connecting bracket is fixed on the unlocking rod, and the cable assembly is connected to the cable connecting bracket; when the cable assembly is pulled, the cable connecting bracket can be driven to rotate, thereby driving the unlocking rod to rotate, realizing the unlocking of the rotator, and then enabling the armrest assembly to flip downward, and the armrest assembly is equipped with a flipping buffer device.

[0005] In the above scheme: the inner end of the rotator is the inner connecting plate, and the outer end is the rotator core part. The outer end of the rotator core part is welded with the outer connecting plate and the hollow connecting bracket in sequence from the inside to the outside. The rotating shaft is welded to the hollow connecting bracket, and the unlocking rod is welded to the inner connecting plate. Each rotator is provided with an unlocking rod. The unlocking rods of the two rotators are coaxially welded together, and the cable connecting bracket is welded to one of the unlocking rods. The coaxial welding of the two rotators is conducive to ensuring the consistency of rotation, and after welding, the two rotators can be unlocked by rotating one of the unlocking rods, which is conducive to simplifying the structure.

[0006] The inner and outer ends of the rotator produce relative rotation, which can unlock the rotation function, similar to a recliner.

[0007] In the above scheme: the armrest assembly includes an armrest upper shell, an armrest lower shell, and an armrest frame wrapped between the armrest upper shell and the armrest lower shell, the armrest frame includes two symmetrically arranged longitudinal beams, the front ends of the two longitudinal beams are welded with frame connecting tubes, a guide sleeve mounting sheet metal is welded between the two frame connecting tubes, a cross beam is welded between the front ends of the two longitudinal beams, a lower connecting plate is welded between the rear ends of the two longitudinal beams, and the inner connecting plate is clamped on the lower connecting plate so that the lower end of the armrest assembly is clamped with the inner ends of the two rotators. The traditional armrest frame structure has low strength. The armrest frame of the present invention is an integral sheet metal with three connections between the two sides. The front end is connected by a guide sleeve mounting sheet metal, the front and middle ends are connected by a cross beam, and the rear end is connected by a lower connecting plate. The overall structural strength is high and the supporting capacity is strong.

[0008] In the above scheme: the flipping buffer device includes a gas spring, wherein a gas spring bracket is provided on a longitudinal beam, a gas spring connecting ball head is provided on the gas spring bracket, a connecting pin is threadedly fixed on an outer connecting plate, and the two ends of the gas spring are respectively movably connected to the gas spring connecting ball head and the connecting pin. The buffering function is achieved by the gas spring to avoid excessive impact force when the armrest assembly is flipped. Specifically, a support ear can be provided on the corresponding outer connecting plate, and the connecting pin is provided on the support ear.

[0009] In the above solution: the gas spring bracket and the link pin are located on the same side to ensure smooth extension and retraction of the gas spring.

[0010] In the above scheme: the armrest lower shell is connected to the armrest frame by bolts, the bolts are hidden inside the shell of the armrest lower shell, and the armrest upper shell is snap-fitted to the upper end of the armrest lower shell.

[0011] The armrest frame of the traditional middle armrest is only snapped onto the armrest outer shell, with poor assembly stability and prone to friction noise. The armrest frame of the present invention is fixedly connected to the lower shell of the armrest by bolts, has high stability, is not easy to loosen, and the bolts are hidden inside the lower shell of the armrest, avoiding the bolts being exposed to the outside and affecting the flatness and aesthetics of the armrest assembly.

[0012] In the above scheme: the cable assembly includes an unlocking handle and a cable, the cable is connected between the unlocking handle and the cable connection bracket, and the unlocking handle is movable on the armrest assembly. Pulling the unlocking handle realizes flip unlocking, and the rotator automatically locks after the armrest assembly returns to its original position.

[0013] In the above scheme: the backrest connecting bracket is a U-shaped structure, the top of the backrest connecting bracket is fixed to the backrest frame by bolts, and the two rotating shafts are fixed one by one to the inner sides of the two ends of the backrest connecting bracket. The connection structure is simple and can be quickly assembled on the backrest frame.

[0014] The beneficial effects of the present invention are as follows: pulling the cable assembly can drive the cable connecting bracket to rotate, thereby driving the unlocking rod to rotate, realizing the unlocking of the rotator, and then allowing the armrest assembly to flip downward. When the armrest assembly flips, it is affected by the buffer device and its impact speed can be reduced. That is, the cable assembly, the rotator assembly, the armrest assembly and the flipping buffer device work together to realize the armrest function. The overall structure is simple and easy to operate, and each assembly can be processed separately and then assembled finally. The processing and assembly are convenient and the maintenance cost is low. The flipping control of the armrest assembly is realized by the two rotators, which has good stability and high strength, and the two rotators are coaxially connected, which is conducive to ensuring its consistency.
