Description

Technical Field

[0001] This invention belongs to the field of automotive interior parts technology. Specifically, this invention relates to a double-opening armrest box for automobiles and its assembly method. Background Technology

[0002] Current automotive double-opening armrest boxes typically include a storage compartment, an armrest cover, a torsion spring, and a pivot. The storage compartment connects to the sub-dashboard, and the armrest cover connects to the storage compartment and a damper via the pivot and torsion spring, enabling damped opening and closing. However, current automotive double-opening armrest boxes have the following drawbacks: 1. The handrail cover does not completely cover the damper, which makes the damper prone to shaking or even falling off during assembly, affecting product reliability and user experience.

[0003] 2. The storage box does not have a fixed position for the torsion spring, making it difficult to control when assembling the torsion spring. The torsion spring is prone to displacement, requiring repeated adjustments and resulting in low assembly efficiency. Summary of the Invention

[0004] This invention provides a double-opening armrest box for automobiles and an assembly method thereof, in order to solve the technical problems existing in the background art.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a double-opening armrest box for automobiles, comprising a storage box, an armrest cover plate, a damper, a torsion spring, and a pivot shaft. The storage box is connected to the sub-dashboard. The storage box is provided with a first hinge seat. The lower end of the hinge seat is provided with a torsion spring insertion hole and a lower limiting groove. The first hinge seat is provided with a hollow bushing on one side and a first damping limiting groove on the other side. The armrest cover plate is provided with a second hinge seat, a damping mounting hole, and a second damping limiting groove. The armrest cover plate is also provided with a torsion spring retaining groove. The damper is connected to the damping mounting hole and is limited by the damping limiting groove one and the damping limiting groove two. The torsion spring is sleeved on the hollow shaft sleeve. One end of the torsion spring is inserted into the torsion spring insertion hole. The part of the torsion spring after being bent at 90° is engaged with the lower limiting groove. The other end of the torsion spring is engaged with the torsion spring retaining groove. The rotating shaft passes through the hinge seat two, the hollow shaft sleeve and the hinge seat one in sequence until it is inserted into the damper.

[0006] A method for assembling a double-opening armrest box in a car, the specific steps of which are as follows: Step S1: Insert the damper into the damping mounting hole of the armrest cover plate, and limit it by the second damping limiting groove; Step S2: Place the torsion spring onto the hollow bushing, insert one end of the torsion spring into the torsion spring insertion hole, and engage the part of the torsion spring after it is bent at 90° with the lower limit groove. Step S3: Place the damper axis in the armrest cover plate of step S1 coaxially and collinearly with the hollow bushing axis on one side of the hinge seat, and limit the damper in the damping limiting groove. Step S4: Pass the rotating shaft through the second hinge seat, the hollow bushing, and the first hinge seat in sequence until it is inserted into the damper; Step S5: Insert the other end of the torsion spring into the torsion spring retainer.

[0007] The beneficial effects of adopting the above technical solutions are: 1. The double-opening armrest box of the present invention, by providing damping mounting holes and damping limiting grooves on the armrest cover plate, ensures that the armrest cover plate completely covers the damper, preventing the damper from shaking and falling off during assembly.

[0008] 2. In the double-opening armrest box of the automobile of the present invention, the torsion spring is sleeved on the hollow bushing, one end of the torsion spring is inserted into the torsion spring insertion hole, the part of the torsion spring after being bent at 90° is engaged with the lower limit groove, and the other end of the torsion spring (4) is engaged with the torsion spring slot, so as to ensure that the position of the torsion spring is accurate and will not be offset during assembly. Improve assembly accuracy and efficiency.

[0009] 3. The assembly method of the double-opening armrest box of the automobile of the present invention has a simple assembly process, requires no complicated tools, and reduces production costs and time. Attached Figure Description
