TECHNICAL FIELD

[0001] The present application relates to the technical field of automobile armrests, in particular to an automobile armrest structure. BACKGROUND

[0002] The automobile armrest is an important part of the seat, which is used for the driver to rest the arm when driving for a long time due to holding the steering wheel. The lower part of the armrest is an armrest box. In order to provide more storage space for the automobile, a storage compartment for storing articles is designed in the armrest box. The armrest is generally connected to the armrest box through a hinge mechanism. The armrest can be opened and closed by rotating the hinge mechanism. At present, the hinge mechanism mostly relies on spring torsion or its own gravity to achieve automatic closing. The armrest cannot be suspended during opening and closing.

[0003] The Chinese invention patent with the application number 2022103671125 discloses a multi-angle suspending automobile armrest hinge mechanism. When the armrest is opened and closed, the suspension controller is used to complete the suspension of the armrest by means of the extension rod on the suspension controller being clamped between the clamping blocks on the suspension angle control disc.

[0004] The Chinese invention patent with the application number 202120568598X discloses an automobile armrest hinge assembly. During use, the limiting spring tension support restricts the position of the limiting toothed rod and the cooperating toothed rod, and the support spring tension support restricts the abutment of the spring rod and the armrest support plate, thereby facilitating the positioning and closing of the armrest and avoiding abnormal noise caused by shaking during driving.
