Description

Technical Field

[0001] The utility model relates to the technical field of vehicle seats, in particular to a vehicle armrest structure capable of flipping. Background Art

[0002] To improve the comfort of vehicle seats, middle armrests are integrated in the rear seats of some vehicle models. Generally, the middle armrest of the rear seat is foldable. When the armrest is not needed, it is stored in the rear seat backrest; when the armrest is needed, the armrest is laid flat through a flipping mechanism. The traditional flipping mechanism cannot adjust the flipping speed of the armrest. When the armrest is laid down, there is a large instantaneous impact generated by its own gravity, which is inconvenient to operate and easily causes damage to the armrest. Moreover, the traditional flipping 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 Utility Model

[0003] Aiming at the problems existing in the above-mentioned prior art, the utility model aims to provide a vehicle armrest structure capable of flipping, so as to solve the problems of poor stability of the traditional flipping mechanism, low locking strength, and large impact force during flipping.

[0004] To achieve the above object, the utility model provides a vehicle armrest structure capable of flipping, which includes an armrest assembly and a backrest connection bracket for connecting with the backrest skeleton, and further includes a rotator assembly and a cable assembly. The rotator assembly includes two rotators arranged coaxially. The outer ends of the two rotators are respectively fixedly connected with the backrest connection bracket through rotating shafts. The two rotating shafts are on the same axis. The lower end of the armrest assembly is hinged on the two rotating shafts and is clamped with the inner ends of the two rotators. The inner ends of the two rotators are connected by an unlocking rod. The unlocking rod and the rotator are on the same axis. A cable connection bracket is fixedly arranged on the unlocking rod. The cable assembly is connected with the cable connection bracket. By pulling the cable assembly, the cable connection bracket can be driven to rotate, thereby driving the unlocking rod to rotate, realizing the unlocking of the rotator, and further enabling the armrest assembly to flip downward. The armrest assembly is equipped with a flipping buffer device.

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

[0006] Relative rotation occurs at both the inner and outer ends of the rotator, enabling the unlocking of the rotation function, similar to an angle adjuster.

[0007] In the above solution: The armrest assembly includes an upper armrest housing, a lower armrest housing, and an armrest skeleton wrapped between the upper and lower armrest housings. The armrest skeleton includes two symmetrically arranged longitudinal beams. At the front ends of both longitudinal beams, there are welded skeleton connecting pipes. Between the two skeleton connecting pipes, there is a guide sleeve mounting sheet metal welded. Between the front ends of the two longitudinal beams, there is a cross beam welded. Between the rear ends of the two longitudinal beams, there is a lower connecting plate welded. The inner connecting plate is snap-fitted onto the lower connecting plate so that the lower end of the armrest assembly is snap-fitted with the inner ends of the two rotators. The traditional armrest skeleton has relatively low structural strength. The armrest skeleton of the present utility model is an integral sheet metal, with three connections provided between its two sides. The foremost end is connected through the guide sleeve mounting sheet metal, the front middle part is connected through the cross beam, and the rear end is connected through the lower connecting plate. The overall structure has high strength and strong supporting ability.

[0008] In the above solution: The flipping buffer device includes a gas spring. On one of the longitudinal beams, there is a gas spring bracket. On the gas spring bracket, there is a gas spring link ball head. On one of the outer connecting plates, there is a link pin fixed by threading. The two ends of the gas spring are respectively movably connected to the gas spring link ball head and the link pin. The buffer function is realized through the gas spring to avoid excessive impact force when the armrest assembly flips. Specifically, lugs can be provided on the corresponding outer connecting plate, and the link pin is arranged on the lugs.

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

[0010] In the above solution: The lower armrest housing is connected to the armrest skeleton by bolts, and the bolts are hidden inside the housing of the lower armrest housing. The upper armrest housing is snap-fitted and fastened to the upper end of the lower armrest housing.

[0011] The armrest skeleton of the traditional middle armrest is only snap-fitted onto the armrest outer shell, with poor assembly stability and prone to frictional noise. The armrest skeleton of the present utility model is fixedly connected to the lower armrest housing by bolts, with high stability and not easy to loosen. Moreover, the bolts are hidden inside the lower armrest housing, avoiding the exposure of the bolts outside, which affects the flatness and aesthetics of the appearance of the armrest assembly.

[0012] In the above solution: 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 movably limited on the armrest assembly. Pulling the unlocking handle realizes flipping unlocking, and the rotator automatically locks after the armrest assembly returns to its position.

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

[0014] The beneficial effects of the present utility model are as follows: By pulling the cable assembly, the cable connection bracket can be driven to rotate, thereby driving the unlocking lever to rotate, realizing the unlocking of the rotator, and further enabling the armrest assembly to be turned downward. When the armrest assembly is turned over, 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 turning buffer device cooperate to realize the armrest function. The overall structure is simple, the operation is convenient, and each assembly can be processed separately and then assembled finally. The processing and assembly are convenient, and the maintenance cost is low; the turning of the armrest assembly is controlled by two rotators, with good stability and high strength, and the two rotators are coaxially connected, which is beneficial to ensuring their consistency.
